Open versus closed reduction and internal fixation in treatment of unstable pelvic fractures: a multicenter cohort study of long-term prognosis / 中华创伤骨科杂志

Objective:To compare the long-term prognosis between open versus closed reduction and internal fixation in the treatment of unstable pelvic fractures.Methods:The data of 402 consecutive patients with unstable pelvic fracture were retrospectively analyzed who had been treated at The First Medical Center and The Fourth Medical Center, PLA General Hospital, and Strategic Support Force Specialty Medical Center from March 2011 to March 2017. This cohort was divided into 2 groups according to the reduction methods. In the open group of 194 cases subjected to open reduction and internal fixation, there were 133 males and 61 females with a median age of 43.0 (30.7, 51.0) years, and 35 cases of type B and 159 cases of type C by the Tile classification. In the closed group of 208 cases subjected to closed reduction and internal fixation, there were 115 males and 93 females with a median age of 45.5 (32.0, 56.0) years, and 40 cases of type B and 168 cases of type C by the Tile classification. The 2 groups were compared in terms of 12-items Short Form Health Survey (SF-12) scores [physical component summary (PCS) and mental component summary (MCS)] at the last follow-up, time from injury to operation, frequency of intraoperative X-ray fluoroscopy, intraoperative and postoperative blood transfusion, operation time, and quality of postoperative fracture reduction.Results:There was no statistically significant difference between the 2 groups in the preoperative general data except for the gender, showing the 2 groups were comparable ( P>0.05). This cohort of 402 patients was followed up for 7.8(6.2, 8.8) years. At the last follow-up, the PCS [49.9 (45.4, 55.4) points] and MCS [53.1 (46.4, 57.6) points] in the closed group were significantly higher than those in the open group [48.2 (41.4, 52.7) and 46.5 (40.6, 53.6) points] ( P<0.05). The closed group incurred significantly shorter time from injury to operation [6 (5, 8) d] and operation time [180 (126, 260) min] than the open group [9 (6, 13) d and 240 (165, 334) min], significantly less intraoperative and postoperative blood transfusion [1.5 (0, 4.0) U] than the open group [5.0 (2.9, 8.0) U], significantly higher frequency of intraoperative X-ray fluoroscopy [104.5 (85.0, 132.0) times] than the open group [21.0 (18.0, 26.0) times], and a significantly higher excellent and good rate of postoperative fracture reduction (92.8%, 193/208) than the open group (86.6%, 168/194) (all P<0.05). Conclusion:In the treatment of patients with unstable pelvic fractures, compared with open reduction and internal fixation, closed reduction and internal fixation can not only significantly shorten the waiting time and operation time of patients, reduce the transfusion during operation, but also achieve better fracture reduction to ultimately improve the quality of life of patients.

There were 346 males and 395 females, aged 55(range, 17?86)years. Observation indicators: (1) neoadjuvant treatment; (2) surgical and postoperative situations; (3) follow-up; (4) stratified analysis. Follow-up was conducted using outpatient examination or telephone interview. Patients were followed up once every 3?6 months during neoadjuvant therapy and once every 6?12 months after radical surgery to detect tumor recurrence and survival of patient up to April 2022. Measurement data with normal distribution were represented as Mean± SD. Measurement data with skewed distribution were represented as M(range), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using chi-square test or Fisher exact probability. The Kaplan-Meier method was used to draw survival curves and calculate survival rates. Log-rank test was used for survival analysis. The COX regression model was used for univariate and multivariate analyses. Propensity score matching was done by the 1∶1 nearest neighbor matching method, and the matching tolerance was 0.02. Results:(1) Neoadjuvant therapy. Of the 741 patients, 34 cases received neoadjuvant therapy for 8(range, 3?44)months. Cases assessed as partial response, stable disease and progressive disease before the radical surgery of the 34 cases were 21, 9, 4, respectively. The tumor diameter of the 34 patients before the neoadjuvant therapy and before the radical surgery were 8.0(range, 3.0?26.0)cm and 5.3(range, 3.0?18.0)cm, with the regression rate as 31.9%(range, ?166.7% to 58.3%). (2) Surgical and postoperative situations. Of the 741 patients, 34 cases underwent radical surgery after receiving neoadjuvant therapy, and 707 cases underwent radical surgery directly. All the 741 patients underwent radical surgery successfully, in which 633, 102 and 6 cases received open surgery, laparoscopic surgery and endoscopic treatment, respectively. Of the 633 cases receiving open surgery and the 102 cases receiving laparoscopic surgery, cases with surgical resection range as pancreatoduodenectomy (PD) was 238, and cases with surgical resection range as duodenal limited resection, including duodenal wedge resection, distal gastrectomy, segmental duodenal resection, local resection of duodenal tumor or segmental duodenum combined with subtotal gastrectomy, was 497, 226, 55, 204, 12. Of the 741 patients, 131 cases had post-operative complications including 113 cases with grade Ⅰ?Ⅱ complications and 18 cases with ≥ grade Ⅲ complications of the Clavien-Dindo classification. The duration of postoperative hospital stay of the 741 patients was 13(range, 4?120)days. Of the 707 patients receiving direct radical surgery, 371 cases were evaluated as extremely low risk, low risk, medium risk of the modified National Institutes of Health (NIH) risk classification after surgery, and 336 cases were evaluated as high risk in which 205 cases receive postoperative adjuvant imatinib therapy with the treatment time as 24(range, 6?110)months. (3) Follow-up. All the 741 patients were followed up for 58(range, 7?150)months. During the follow-up, 110 patients had tumor recurrence and metastasis. The 1-, 3-, 5-year overall survival rates and 1-, 3-, 5-year disease-free survival rates of the 741 patients were 100.0%, 98.6%, 94.5% and 98.4%, 90.9%, 84.9%, respectively. The 1-, 3-, 5-year overall survival rates and 1-, 3-, 5-year disease-free survival rates of the 707 patients receiving direct radical surgery were 100.0%, 98.5%, 94.3% and 98.4%, 91.1%, 85.4%, respectively. (4) Stratified analysis. ① Analysis of prognostic factors in patients undergoing radical surgery directly. Results of univariate analysis showed that primary tumor location, tumor diameter, mitotic count, modified NIH risk classification and tumor gene information were related factors affecting the overall survival of 707 patients with primary duodenal GIST who underwent direct radical surgery ( hazard ratio=0.43, 0.18, 0.22, 0.06, 0.29, 95% confidence intervals as 0.20?0.93, 0.09?0.35, 0.10?0.50, 0.03?0.12, 0.09?0.95, P<0.05). The primary tumor location, tumor diameter, mitotic count, modified NIH risk classification were related factors affecting the disease-free survival of 707 patients with primary duodenal GIST who underwent direct radical surgery ( hazard ratio=0.65, 0.25, 0.25, 0.10, 95% confidence intervals as 0.41?1.03, 0.17?0.37, 0.15?0.42, 0.07?0.15, P<0.05). Results of multivariate analysis showed that primary tumor located at the horizontal segment of duodenum, mitotic count >5/50 high power field, tumor gene KIT exon 9 mutation were independent risk factors affecting the overall survival of 365 patients with primary duodenal GIST after removing 342 patients without tumor gene information who underwent direct radical surgery ( hazard ratio=2.85, 2.73, 3.13, 95% confidence intervals as 1.12?7.20, 1.07?6.94, 1.23?7.93, P<0.05). Tumor diameter >5 cm and mitotic count >5/50 high power field were independent risk factors affecting the disease-free survival of 707 patients with primary duodenal GIST who underwent direct radical surgery ( hazard ratio=3.19, 2.98, 95% confidence intervals as 2.05?4.97, 1.99?4.45, P<0.05). ② Effect of postoperative adjuvant therapy on prognosis of high-risk patients of modified NIH risk classification. Of the 336 patients evaluated as high risk of the modified NIH risk classification, the 5-year overall survival rate and 5-year disease-free survival rate were 94.6% and 77.3% in the 205 cases with postoperative adjuvant therapy, versus 83.2% and 64.4% in the 131 cases without postoperative adjuvant therapy, showing significant differences between them ( χ2=8.39, 4.44, P<0.05). Of the 205 patients evaluated as high risk of the modified NIH risk classification who received postoperative adjuvant therapy, there were 106 cases receiving postoperative adjuvant therapy <36 months, with the 5-year overall survival rate and 5-year disease-free survival rate were 87.1% and 58.7%, and there were 99 cases receiving post-operative adjuvant therapy ≥36 months, with the 5-year overall survival rate and 5-year disease-free survival rate were 100.0% and 91.5%. There were significant differences in the 5-year overall survival rate and 5-year disease-free survival rate between the 106 patients and the 99 patients ( χ2=13.92, 29.61, P<0.05). ③ Comparison of clinical efficacy of patients with different surgical methods. Before propensity score matching, cases with primary tumor located at bulb, descending, horizontal, ascending segment of duodenum, cases with tumor diameter ≤5 cm and >5 cm were 95, 307, 147, 34, 331, 252, in the 583 patients receiving open surgery with complete clinical data, versus 15, 46, 17, 5, 67, 16 in the 83 patients receiving laparoscopic surgery with complete clinical data, showing no significant difference in the primary tumor location ( χ2=0.94, P>0.05), and a significant difference in the tumor diameter ( χ2=17.33, P<0.05) between them. After propensity score matching, the above indicator were 16, 39, 20, 8, 67, 16 in the 83 patients receiving open surgery, versus 15, 46, 17, 5, 67, 16 in the 83 patients receiving laparoscopic surgery, showing no significant difference between them ( χ2=1.54, 0.00, P>0.05). Cases with postoperative complications, cases with grade Ⅰ?Ⅱ complica-tions and ≥grade Ⅲ complications of the Clavien-Dindo classification, duration of postoperative hospital stay, the 5-year overall survival rate and 5-year disease-free survival rate were 17, 12, 5, 11(range, 5?120)days, 92.0%, 100.0% in the 83 patients receiving open surgery, versus 9, 7, 2, 11(range, 5?41)days, 91.6%, 97.3% in the 83 patients receiving laparoscopic surgery, showing no signi-ficant difference in postoperative complications, duration of postoperative hospital stay, the 5-year overall survival rate and 5-year disease-free survival rate ( χ2=2.91, Z=3 365.50, χ2=3.02, 1.49, P>0.05) between them. There was no significant difference in complications of the Clavien-Dindo classification between them ( P>0.05). ④ Comparison of clinical efficacy of patients with primary tumor located at the descending segment of duodenum who underwent surgery with different surgical resection scopes. Before propensity score matching, cases with tumor diameter ≤5 cm and >5 cm, cases with tumor located at opposite side of mesangium and mesangium were 71, 85, 28, 128 in the 156 patients with primary tumor located at the descending segment of duodenum who underwent PD with complete clinical data, versus 92, 41, 120, 13 in the 133 patients with primary tumor located at the descending segment of duodenum who underwent duodenal limited resection with complete clinical data, showing significant differences between them ( χ2=16.34, 150.10, P<0.05). After propensity score matching, the above indicator were 28, 13, 16, 25 in the 41 patients with primary tumor located at the descending segment of duodenum who underwent PD with complete clinical data, versus 28, 13, 16, 25 in the 41 patients with primary tumor located at the descending segment of duodenum who underwent duodenal limited resection with complete clinical data, showing no significant difference between them ( χ2=0.00, 0.00, P>0.05). Cases with postopera-tive complications, cases with grade Ⅰ?Ⅱ complications and ≥grade Ⅲ compli-cations of the Clavien-Dindo classification, duration of postoperative hospital stay, the 5-year overall survival rate and 5-year disease-free survival rate were 13, 11, 2, 15(range, 9?62)days, 94.2%, 64.3% in the 41 patients with primary tumor located at the descending segment of duodenum who underwent PD with complete clinical data, versus 9, 8, 0, 15(range, 7?40)days, 100.0%, 78.8% in the 41 patients with primary tumor located at the descending segment of duodenum who underwent duodenal limited resection with complete clinical data, showing no significant difference in post-operative complica-tions, the 5-year overall survival rate and 5-year disease-free survival rate ( χ2=0.99, 0.34, 1.86, P>0.05) between them. There was no significant difference in complications of the Clavien-Dindo classification ( P>0.05) and there was a significant difference in duration of postopera-tive hospital stay ( Z=614.50, P<0.05) between them. Conclusions:The clinical efficacy of radical surgery for duodenal GIST are ideal. Primary tumor located at the horizontal segment of duodenum, mitotic count >5/50 high power field, tumor gene KIT exon 9 mutation are independent risk factors affec-ting the overall survival of patients undergoing direct radical surgery and tumor diameter >5 cm and mitotic count >5/50 high power field are independent risk factors affecting the disease-free survival of patients. There is no significant difference in the short-term efficacy and long-term prognosis between patients undergoing open surgery and laparoscopic surgery. For patients with primary tumor located at the descending segment of duodenum, the duration of postoperative hospital stay is longer in patients undergoing PD compared with patients undergoing duodenal limited resection. For patients evaluated as high risk of the modified NIH risk classification, posto-perative adjuvant therapy and treatment time ≥36 months are conducive to improving the prognosis of patients.

The LDL/HDL ratio predicts long-term risk of coronary revascularization in ST-segment elevation myocardial infarction patients undergoing percutaneous coronary intervention: a cohort study

Clinical indicators do not adequately predict the long-term prognosis of patients with ST-segment elevation myocardial infarction (STEMI) following percutaneous coronary intervention (PCI). The low-density lipoprotein (LDL)/high-density lipoprotein (HDL) ratio is expected to be a reliable predictor of the long-term prognosis of these patients. This study aimed to explore the correlation between the LDL/HDL ratio and long-term prognosis in STEMI patients undergoing PCI. Patients with confirmed STEMI who underwent PCI in 7 hospitals in China from January 2009 to December 2011 were enrolled. Information about clinical endpoints, including all-cause death and major adverse cardiovascular events, was collected. Overall, 915 patients were included for analysis, the average follow-up time was 112.2 months. According to the LDL/HDL ratio, the patients were divided into 3 groups using the three-quantile method: low (LDL/HDL≤1.963), medium (1.963<LDL/HDL<2.595), and high (LDL/HDL≥2.595) LDL/HDL groups. The rate of coronary revascularization was higher in the high LDL/HDL group (28.52%) than in the low (17.38%, P=0.001) and medium (19.34%, P=0.010) LDL/HDL groups. The hazard ratio of coronary revascularization was significantly higher in the high LDL/HDL group than in the low (P=0.007) and medium (P=0.004) LDL/HDL groups. Increased LDL/HDL ratio was an independent risk factor for long-term coronary revascularization in STEMI patients undergoing PCI (HR=1.231, 95%CI: 1.023-1.482, P=0.028). These findings suggest that an increased LDL/HDL ratio was an independent risk factor for long-term coronary revascularization in STEMI patients undergoing PCI. The risk of coronary revascularization was significantly increased in patients with LDL/HDL≥2.595.

The long-term outcomes of one-stage hybrid procedure for aortic arch pathologies / 中华胸心血管外科杂志

Objective:To analyze the long-term outcomes of hybrid arch repair(HAR) treating aortic arch pathologies.Methods:Between January 2009 and January 2018, 87 consecutive patients underwent HAR for aortic arch pathologies at Beijing Anzhen Hospital. 76 were males. 2 cases were in zone 0, 46 cases were in zone 1, and 39 cases were in zone 2. The zones of the aortic arch were defined following the Ishimaru classification.Results:Five(5.7%) operative death occurred. 13 patients(19.1%) died during the follow-up. The overall survival rate was 88.4%, 83.3%, 83.3%, 49.8% at 1, 3, 5, 10 year, respectively. Multivariate Cox proportional risk analysis showed that stroke( HR=20.626, 95% CI: 2.698-157.685, P=0.004) was an independent risk factor for short-term death. Stroke( HR=16.234, 95% CI: 4.103-64.229, P<0.001) and spinal cord infury( HR=11.060, 95% CI: 2.150-56.893, P=0.004) were independent risk factors for long-term death. Conclusion:In conclusion, HAR could be an alternative procedure for the patients that are not suitable for open repair under the premise of strict control of indications. In the future, the risk assessment system and uniform operational indications for HAR should be further established.

Analysis of the 10-year survival results of patients with esophageal squamous cell carcinoma achieving clinical complete remission after radical radiotherapy / 中华放射肿瘤学杂志

Objective:To investigate the long-term prognosis and failure mode of patients with esophageal squamous cell carcinoma who achieved clinical complete remission (cCR) after receiving radical radio (chemo) therapy.Methods:Clinical data of 183 patients with esophageal squamous cell carcinoma eligible for inclusion criteria who received treatment in our hospital from January 2009 to December 2012 were retrospectively analyzed. The factors that affected the long-term prognosis of patients were identified, and the failure mode of cCR patients and the prognosis after failure were analyzed. SPSS 19.0 statistical software was used for data analysis.Results:As of the follow-up date, the 1-, 3-, 5-, and 10-year overall survival (OS) rates and disease-free survival (DFS) rates of the entire group were 83.1%, 53.4%, 36.2%, 12.8% and 68.9%, 45.9%, 30.5%, 12.0%, respectively. The median OS and DFS were 41.3 months and 33.4 months. The results of multivariate analysis showed that cT staging, cN staging and prescribed dose were the independent factors affecting the OS ( P=0.001, <0.001, 0.003); hoarseness, lesion length, cT staging, cN staging and prescribed dose were the independent factors that affected the DFS ( P=0.002, 0.033, 0.009, <0.001, 0.003). In the whole group, 72 cases (39.3%) had local regional recurrence, 58 cases (31.7%) had distant metastasis, and 26 cases (14.2%) had local regional recurrence with distant metastasis. Among 104 patients after treatment failure, the prognosis of patients receiving salvage treatment was significantly better than that of their counterparts receiving maintenance treatment ( χ2=39.153, P<0.001). Conclusions:The long-term prognosis of patients with esophageal squamous cell carcinoma who achieved cCR after receiving radical radio (chemo) therapy is still unsatisfactory. Clinically, it is necessary to strengthen the clinical observation and follow-up of these patients. The main treatment failure mode of cCR patients is local regional recurrence. Active salvage treatment can significantly improve clinical prognosis of these patients.

Effect of Shenmai Injection on Long-Term Prognosis of Patients with Chronic Heart Failure: A Multicenter, Large Sample Capacity, Long-Term Follow-Up Retrospective Cohort Study / 中国结合医学杂志

OBJECTIVE@#To explore the effect of Shenmai Injection (SMI) on the long-term prognosis of patients with chronic heart failure (CHF).@*METHODS@#The Hospital Information System was used to extract data of CHF patients, and the retrospective cohort study was conducted for analysis. In non-exposed group, standardized Western medicine treatment and Chinese patent medicine or decoction were applied without combination of SMI while in the exposed group, SMI were applied for more than 7 days. Evaluation indicators are followed with New York Heart Association functional classification (NYHA classification), left ventricular ejection fraction (LVEF), N-terminal brain natriuretic peptide precursor (NT-ProBNP), cardiogenic death and heart failure (HF) readmission. Statistical analysis includes Kaplan-Meier analysis and Cox regression which are used to explore the relationship between SMI and outcome events.@*RESULTS@#A total of 1,211 eligible CHF patients were involved and finally 1,047 patients were followed up successfully. After treatment, the cases of NYHA classification decline in the exposed and non-exposed groups accounted for 64.30% and 43.45%, respectively; the improvement values of LVEF were 8.89% and 7.91%, respectively; the improvement values of NT-ProBNP were 909 pg/mL and 735 pg/mL, respectively. After exposure on SMI, the rates of cardiogenic death and HF readmission reduced from 15.43% to 10.18% and 38.93% to 32.37%. According to Kaplan-Meier analysis, the log-rank P value of SMI and cardiogenic death was 0.014, while the counterpart of SMI and HF readmission was 0.025. Cox regression analysis indicated that for cardiogenic death, age, cardiomyopathy, diabetes, and NYHA classification were risk factors while β-blockers, aldosterone receptor antagonists, Chinese patent medicine/decoction and SMI were protective factors. Likewise, for HF readmission, age, cardiomyopathy, and NYHA classification were risk factors while SMI was a protective factor.@*CONCLUSION@#Combination with SMI on the standardized Western medicine treatment can effectively reduce cardiogenic mortality and readmission rate in CHF patients, and thereby improve the long-term prognosis.

Clinical value of hemoglobin in the assessment of long-term prognosis of stroke after rehabilitation treatment / 中国基层医药

Objective:To investigate the clinical value of hemoglobin in the assessment of long-term prognosis of stroke after rehabilitation treatment.Methods:A total of 168 patients with stroke who received treatment in Ruian People's Hospital, China between January 2018 and January 2019 were included in this study. All of them received rehabilitation treatment. They were divided into Hb < 120 g/L group ( n = 36 and Hb ≥ 120 g/L group ( n = 132) according to Hb level before rehabilitation treatment. All patients were followed up for 12 months. General data, and simplified Fugl-Meyer Assessment (FMA) score and modified Barthel Index (MBI) before and after treatment were compared between the two groups. Pearson correlation was used to analyze the correlation between Hb level and simplified FMA score and MBI. The area under the receiver operating characteristic (ROC) curve was used to evaluate the efficacy of Hb level in predicting stroke recurrence. Results:There were no significant differences in gender, age and body mass index between the two groups (all P > 0.05). After treatment, simplified FMA score and MBI in the Hb ≥ 120 g/L group were (85.39 ± 8.27) points and (87.14 ± 8.85) points, respectively, which were significantly higher than those in the Hb < 120 g/L group [(79.82 ± 6.18) points, (80.06 ± 6.97) points, t = 5.625, 6.012, both P < 0.05). Pearson correlation results revealed that Hb level before rehabilitation was positively correlated with FMA score and MBI ( r = 0.425, 0.362, both P < 0.05). During the follow-up period, stroke recurred in 27 (16.07%) out of 168 patients. The area under the ROC curve for Hb level before treatment as a predictor of stroke recurrence was 0.915, which was significantly greater than the National Institutes of Health Stroke Scale score 0.630 ( Z = 2.652, P < 0.05). Conclusion:The long-term prognosis of stroke patients with low Hb level before rehabilitation treatment is poor, and monitoring Hb level is highly effective for predicting stroke recurrence. This study is greatly innovative and scientific. Findings from this study deserve further investigation.

Comparison of short-term rehabilitation and long-term prognosis between laparoscopy and traditional laparotomy for colon cancer / 中国医师进修杂志

Objective:To compare the short-term recovery and long-term prognosis of patients with colorectal cancer by laparoscopy and traditional open surgery.Methods:The clinical data of 86 patients with colon cancer treated by the Changshu NO.1 People′s Hospital from April 2017 to April 2019 were retrospectively analyzed. According to different surgical methods, they were divided into observation group (laparoscopic radical resection of colon cancer, 41 cases) and the control group (traditional laparotomy underwent radical resection of colon cancer, 45 cases). The surgical indicators, short-term recovery, complications, serum anti-inflammatory and pro-inflammatory factor levels, and 3-year tumor-free survival rate between two groups were compared.Results:Compared with the control group, the observation group had less intraoperative blood loss and shorter hospital stay: (120.32 ± 32.43) ml vs. (178.43 ± 39.98) ml, (9.65 ± 2.17) d vs. (12.35) ± 2.68) d; the time to get out of bed for the first time, the time of anal exhaust and the time of eating semiliquid in the observation group were earlier: (2.10 ± 0.23) d vs. (3.03 ± 0.54) d, (3.45 ± 1.02) d vs. (4.29 ± 1.03) d, (4.54 ± 1.09) d vs. (5.30 ± 1.05) d, the differences were statistically significant ( P<0.05). The incidence of complications in the observation group was lower than that in the control group: 12.20% (5/41) vs. 31.11% (14/45), the difference was statistically significant ( χ2 = 4.695, P<0.05). Serum interleukin (IL)-6 and tumor necrosis factor (TNF)-α levels in the observation group were lower than those in the control group: (23.12 ± 6.09) μg/L vs. (31.05 ± 5.3) μg/L, (57.87 ± 10.6) μg/L vs. (62.43 ± 6.8) μg/L; serum IL-4 and transforming growth factor (TGF)-β levels were higher than those in the control group: (155.03 ± 14.53) ng/L vs. (127.87 ± 12.09) ng/L, (26.32 ± 3.09) ng/L vs. (20.87 ± 3.87) ng/L, the differences were statistically significant ( P<0.05). There was no significant difference in the tumor-free survival rate between the two groups at 3-year after operation ( P>0.05). Conclusions:Laparoscopic treatment of colon cancer has the advantages of less trauma, fewer complications, and mild postoperative inflammatory reaction, and has a long-term prognosis comparable to traditional laparotomy.

Objective:To investigate the clinical characteristics, long-term prognosis and changes of pulmonary function in children with idiopathic pulmonary fibrosis (IPF).Methods:The clinical data, long-term prognosis and changes of pulmonary function of children with IPF admitted to the Department of Pediatric Respiratory Center in Children′s Hospital of Chongqing Medical University from January 2008 to December 2018 were retrospectively analyzed.Results:A total of 28 cases were included, with the median age of 3.9 years (range: 0.5 to 15.7 years). Cough (28 cases, 100.0%), tachypnea (25 cases, 89.3%), cyanosis (19 cases, 67.9%), dyspnea (11 cases, 39.3%), Velcho rales (12 cases, 42.9%), inspiratory three concave sign (11 cases, 39.3%), clubbed fingers and toes (6 cases, 21.4%) and diminished breath sounds (5 cases, 17.9%) were main clinical manifestations.Chest high-resolution computed tomography (HRCT) mainly displayed grid shadow, irregular sac-like light-transparent shadow with ho-neycomb changes and dense shadow, partial (7 cases) pulmonary interstitial emphysema/emphysema/pneumomediastinum.Three cases of lung biopsy showed hyperplasia and consolidation of alveolar space and alveolar septal fibrosis, thickening of alveolar wall and coexistence of new and old lesions.In this group, 4 cases did not receive drug therapy due to other reasons (3 cases abandoned therapy, and 1case died of respiratory and circulatory failure during hospitalization). Twenty-four cases were treated with single or combination of oral Prednisone, N-acetylcysteine and Azithromycin.Eleven cases had improved symptoms when discharged, and 13 cases showed no improvement.Twenty-four cases continued to receive oral medication therapy according to the original protocol.Eight cases were followed up for chest HRCT for 3 months to 4 years, the chest HRCT lesions of 7 cases were similar to before, and those of 1 case increased than before.All cases received telephone follow-up for 2 to 7 years; the maximum duration of medication was 4 years.Twelve cases were lost to follow-up, 7 cases had motion limitation, 3 cases died, and 2 cases had no clinical symptom.Three cases were followed up for pulmonary function for 2 to 3 years, among which 2 cases had pulmonary function decreased than before; 1 case had improvements in forced vital capacity as a percentage of the predicted value and peak expiratory flow as a percentage of the predicted value, but decline in forced expiratory volume in the first se-cond as a percentage of the predicted value.Conclusions:The clinical manifestations of children with IPF are lack of specificity.Chest HRCT is of great value in the diagnosis of IPF and preliminary monitoring of the activity of lesion.In the long-term follow-up, some of cases have improvements in symptoms; pulmonary function mostly decreases, but part of indexes can be improved.

Advance in factors affecting the long-term quality of life in children with craniopharyngioma / 国际儿科学杂志

Craniopharyngioma mainly occurs in children aged 5 to 14 years.It′s one of the most common intracranial tumors for children.Although the overall survival rate of pediatric patients with craniopharyngioma has been significantly improved, the long-term quality of life still couldn′t be missed due to the fact that it could invade the important structures around the sellar area, such as the hypothalamus, pituitary gland, and so on.The downward trend is observed among the 5-, 10- and 20-year overall survival rates.Compared with adult-onset patients, childhood-onset patients are at higher risk of hypothalamic involvement, endocrine dysfunction, obesity, have a lower long-term quality of life.In addition to a variety of physical diseases, pediatric patients with craniopharyngioma after surgery may also develop the psychological diseases.Craniopharyngioma should be recognized as a frequently chronic disease which requires constant monitoring of the consequences and medical resources for treatment in order to provide optimal quality of life for pediatric patients.This article reviews the craniopharyngioma-related researches in recent years on the long-term prognosis of childhood-onset patients.

Long term prognostic significance of thrombolysis in myocardial infarction risk score after revascularization in non-ST elevation acute coronary syndrome

Background: Non-ST elevation acute coronary syndrome (NSTE-ACS) patients are complex and varied population. Primarily thrombolysis in myocardial infarction (TIMI) risk score was developed to guide therapy and assess the short term (14 days) prognosis of these patients. However, few studies have evaluated the long term prognostic significance of TIMI risk score after revascularization. This study aims at assessing the long term prognostic significance of TIMI risk score, 36 months after revascularization in NSTE-ACS.Methods: This was a retrospective observational cohort study of consecutive NSTE-ACS patients (n=150) treated by percutaneous coronary intervention between January 2017 to June 2017 in a tertiary care center. TIMI risk score was calculated for each patient at admission. The primary endpoint was a composite of MACE (death, repeat target-vessel revascularization, and non-fatal recurrent MI) at the end of 36 months of follow up. Clinical secondary endpoints included the individual components of the primary endpoint, death, nonfatal recurrent MI, and repeat target vessel revascularization.Results: Baseline characteristics for 150 participants were as follows, age 56±9.5 years, 78.7% male, 25% diabetics, 82% hypertensives, and 36% had hypercholesterolemia. The event rates of the primary endpoint and its components after 36 months were 26.6%. Event rates increased significantly as the TIMI risk score increased as determined by regression analysis (p=0.004). The relative risk increased by 66% as the TIMI risk score increased from low risk category (TIMI score 0-2) to high risk (TIMI score 5-6).Conclusions: TIMI risk score can be used for long term prognostication of NSTE-ACS patients after revascularization, and thus can be used by clinicians for therapeutic decision making.

The incidence and related factors of coronary events among 40-49 years old patients undergoing cardiac thoracotomy without preoperative CAG / 中华心血管病杂志

Objective: To investigate the long-term incidence of coronary events and related factors in patients undergoing cardiac thoracotomy without preoperative coronary angiography (CAG). Methods: This was a retrospective study. The clinical data of patients, aged between 40 and 49 years old, who underwent cardiothoracic surgery, including heart valve surgery, congenital heart disease surgery, cardio great vessels surgery and other non-coronary artery disease (CAD) surgery, in Nanjing Drum Tower Hospital from December 2009 to May 2017, were enrolled. Patients with suspected CAD, or patients with coronary CTA defined calcified coronary arteries received CAG examination prior operation, and the rest patients did not receive routine CAG examinations. The patients who did not receive routine CAG examinations were followed up by telephone. The primary endpoints include death related to coronary arteries, coronary artery bypass graft (CABG) or percutaneous coronary intervention (PCI). The secondary endpoints include the new onset angina, clinically diagnosed CAD or receiving the first and second prevention for CAD. The other outcome events included cardiac death and all-cause mortality. The primary and secondary endpoints were all regarded as coronary events. The patients without preoperative CAG were divided into two groups: the positive group and the negative group, according to the incidence of coronary events during follow-up. Clinical data were compared between the two groups. Results: A total of 952 patients were included. The age was (45.2±2.7) years old, 406(42.65%) patients were male. Preoperative CAG was performed in 73 patients, among whom 9 (12.32%) patients underwent simultaneous CABG. Among the 879 cases who did not undergo coronary angiography before the operation, 18(2.05%) died during perioperative period (hospitalization and within 30 days after discharge). The patients were followed up for (61.6±25.8) months, and 28(3.25%) patients were lost to follow up. During long-term follow up, there were no fatal cases due to severe coronary events and no cases of CABG or PCI. Only 4.41% (38/861) patients had the secondary endpoints, namely the occasional onset of atypical angina. The incidence rate of the long-term coronary events, all-cause mortality and cardiac death were 4.41% (38/861), 1.16% (10/861), 0.46% (4/861) during long-term follow-up. The prevalence of hypertension was significantly higher in positive group than negative group (34.21% (13/38) vs. 20.89% (164/785), P=0.045). Conclusions: It is feasible not to perform preoperative CAG examination for non-CAD patients aged 40-49 years who will undergo cardiac thoracotomy. However, we need to be aware the risk of coronary events in the patients complicating with risk factors of CAD, such as hypertension.

Long-term prognosis of Japanese patients with biologic-naïve Crohn’s disease treated with anti-tumor necrosis factor-α antibodies

BACKGROUND/AIMS: Few reports have described the long-term treatment outcomes of the anti-tumor necrosis factor-α antibody for Japanese Crohn’s disease (CD) patients. The aim of this study was to evaluate them and clarify the clinical factors that affect the long-term prognosis of the anti-tumor necrosis factor-α treatments. METHODS: This was a retrospective, observational, single-center cohort study. Japanese CD patients treated with either infliximab or adalimumab as a first-line therapy were analyzed. The cumulative retention rates of the biologics, relapse-free survival, and surgery-free survival were analyzed using Kaplan-Meier methods. The clinical factors associated with the long-term outcomes were estimated by both the log-rank test and Cox proportional hazard model. RESULTS: The cumulative retention rate was significantly higher in the group with a concomitant elemental diet of ≥900 kcal/day, baseline C-reactive protein (CRP) levels < 2.6 mg/dL, and baseline serum albumin levels ≥3.5 g/dL, respectively. The baseline serum albumin levels were also associated with both relapse-free and surgery-free survival. The lack of concomitant use of an elemental diet ≥900 kcal/day was identified as the only independent risk factor for the withdrawal of the biologics. CONCLUSIONS: Baseline CRP levels and serum albumin levels could affect the long-term outcomes in CD patients. Concomitant elemental diet of ≥900 kcal/day could have a positive influence on clinical treatment course.

A follow-up study on the clinical characteristics among patients with diabetes mellitus combined with acute myocardial infarction / 中华流行病学杂志

Objective@#To investigate the clinical characteristics of diabetic patients combined with acute myocardial infarction (AMI) and to compare the prognosis between diabetic and non- diabetic patients in 4-5 years after the onset of AMI.@*Methods@#Followed the certain inclusive and exclusive criteria, a total of 420 patients with acute myocardial infarction were included and divided into diabetes group (group D) and non-diabetes group (group N) with numbers as 161 people and 259 respectively. Baseline data, clinical information, short-term outcome and long-term prognosis of the two groups were compared and analyzed.@*Results@#Among the patients with diabetes, the average age was older (65.65±11.33 vs. 63.30±15.34), with fewer males (64.59% vs. 79.92%); and more likely to have other complications as hypertension (64.60% vs. 53.28%) or hyperlipidemia (42.24% vs. 26.25%). 59.29% of the patients in group D showed pathological changes in 3 major coronary arteries, which were significantly more than its counterpart (40.83%). The proportion of patients that had undergone the coronary artery bypass, grafting (11.11% vs. 5.31%) appeared also higher. There was no significant difference seen in the short-term outcomes between the two groups, but results from the long-term follow-up program showed that both the incidence of Major Adverse Cardiovascular Events (MACE) (50.67% vs. 27.72%) and the all-cause mortality (20.00% vs. 9.90%) in group D were higher than those appeared in group N (27.72%).@*Conclusions@#Patients suffered from the combination of both diabetes and acute myocardial infarction appeared older in age, more in females, with more complications and the coronary artery lesions were more severe and wider. During hospitalization, no significant difference was seen regarding the short-term outcomes between the two groups but the results from long-term follow-up process showing that the risk of MACE events was significantly higher in patients with type2 diabetes.

Investigation for the Effect of jingizai on Long-term Prognosis and Differences Between Histopathological types in 139 Cases of Ovarian Cancer / 日本東洋医学雑誌

Using the data of 139 ovarian cancer cases at our hospital, we investigated the effect of jingizai on prognosis when it was combined with standard therapy for ovarian cancer and prognosis by histopathological types. Combining jingizai with standard therapy was not effective in cases of stage I-II ovarian cancer, but it was effective in cases of stage III-IV ovarian cancer. Upon examination the effectiveness of jingizai according to histopathological types, we observed some improved prognosis in serous adenocarcinoma and mucinous adenocarcinoma cases ; however, prognosis didn't improve in endometrioid adenocarcinoma and clear cell adenocarcinoma. These results indicate that the effectiveness of combining jingizai with standard therapy may differ depending on histological type of ovarian cancer. When we investigated the difference between the distribution of histopathological types by cancer staging, we frequently found clear cell adenocarcinoma in stage I-II cancer cases. Also, serous adenocarcinoma and poorly differentiated adenocarcinoma had a high frequency among stage III-IV cancer cases. This difference may be the reason that the effectiveness of jingizai is different depending on the advances of each stage. However, no statistical difference was confirmed due to the small number of subjects analyzed. Analysis of larger sample size, which can be collected by performing collaborative studies with other facilities, will be required for more detailed investigation.

Recurrent Painless Thyroiditis in Patients with History of Postpartum Thyroiditis

It is well known that the long-term prognosis of postpartum thyroiditis (PPT) is excellent except recurrent PPT in subsequent pregnancies and risk of progression to permanent hypothyroidism in some patients. However, the prospective observation of PPT patients who have neither consecutive gestation nor any evidence of hypothyroidism were limited. We describe three patients who have history of PPT and showed repeated painless thyroiditis in the span of more than ten years. The clinical courses of repeated painless thyroiditis were the transient thyrotoxicosis, self-limited, and not related to pregnancy. Based on the clinical courses of our three patients, it is recommended to remember that transient painless thyroiditis could be repeated as a possible long-term course of the patients with history of PPT.

Clinical efficacy and long-term outcome of transcatheter occlusion for rupture of valsalva aneurysm ruptured into right atrium / 中国介入心脏病学杂志

Objective To evaluate the clinical safety, efficacy and long-term outcome of transcatheter occlusion for ruptured aortic sinus of valsalva aneurysm (RASA) into the right atrium.Methods Between January 2006 and April 2013, fifteen patients [11 males and 4 females,aged from 21 to 48 years with an mean age of (35.50±8.79) years] with RASA ruptured into the right atrium were enrolled in this study.Domestic made patent ductus arteriosus (applied in six patients) or small waist double-disk ventricular septal defect (applied in nine patients) occluders were used for transcatheter closure.All the patients were followed up for any change in cardiac rhythm,and residual shunt,occluders morphology and possible valve regurgitation by echocardiography.Results All RASA were confirmed by aortography,including eleven cases with rupture of right coronary sinus of valsalva and four cases with rupture of the noncoronary sinus of valsalva shunting into the right atrium.NYHA function class was(2.56±0.63)before the occlusion.Cardiac catheterization showed mean pulmonary arterial pressure and Qp/Qs ratio were (25.38±8.21)mmHg (1 mmHg=0.133 kPa) and 1.34-2.81(1.93±0.39), respectively.Aortic angiography showed that the RSA was 4-10(6.42±1.92)mm at its narrowest end.There was no serious complication during the operation and all the patients had successful transcatheter closure without residual shunt.After transcatheter RASA occlusion, mean pulmonary artery pressure decreased to (16.1±5.3) mmHg (P<0.05).The diameter of right atrium,right ventricle, left atrium and pulmonary artery diameter and left ventricular end-diastolic dimension all showed significant decrease (P<0.01).All patients were followed up for 35-132(78.6±28.57)months.All patients presented with a NYHA function class Ⅰ to Ⅱ cardiac function in their last follow up which was significantly improved compare to pre-occlusion level (P<0.01).There were no infective endocarditis,device displacement and embolism,serious aortic regurgitation,myocardial ischemia,serious arrhythmia or death in any of the patients during follow up.Conclusions Transcatheter closure of Valsalva aneurysm ruptured into right atrium with the domestic made patient ductus arteriosus and small-waist ventricular septal defect occluder is safe and effective with a good long term prognosis.

Intraoperative Motor-Evoked Potential Disappearance versus Amplitude-Decrement Alarm Criteria During Cervical Spinal Surgery: A Long-Term Prognosis

BACKGROUND AND PURPOSE: We studied the clinical significance of amplitude-reduction and disappearance alarm criteria for transcranial electric muscle motor-evoked potentials (MEPs) during cervical spinal surgery according to different lesion locations [intramedullary (IM) vs. nonintramedullary (NIM)] by evaluating the long-term postoperative motor status. METHODS: In total, 723 patients were retrospectively dichotomized into the IM and NIM groups. Each limb was analyzed respectively. One hundred and sixteen limbs from 30 patients with IM tumors and 2,761 limbs from 693 patients without IM tumors were enrolled. Postoperative motor deficits were assessed up to 6 months after surgery. RESULTS: At the end of surgery, 61 limbs (2.2%) in the NIM group and 14 limbs (12.1%) in the IM group showed MEP amplitudes that had decreased to below 50% of baseline, with 13 of the NIM limbs (21.3%) and 2 of the IM limbs (14.3%) showing MEP disappearance. Thirteen NIM limbs (0.5%) and 5 IM limbs (4.3%) showed postoperative motor deficits. The criterion for disappearance showed a lower sensitivity for the immediate motor deficit than did the criterion for amplitude decrement in both the IM and NIM groups. However, the disappearance criterion showed the same sensitivity as the 70%-decrement criterion in IM (100%) and NIM (83%) surgeries for the motor deficit at 6 months after surgery. Moreover, it has the highest specificity for the motor deficits among diverse alarm criteria, from 24 hours to 6 months after surgery, in both the IM and NIM groups. CONCLUSIONS: The MEP disappearance alarm criterion had a high specificity in predicting the long-term prognosis after cervical spinal surgery. However, because it can have a low sensitivity in predicting an immediate postoperative deficit, combining different MEP alarm criteria according to the aim of specific instances of cervical spinal surgery is likely to be useful in practical intraoperative monitoring.

Long-term post-liver-transplantation hyperuricemia and treatment of renal function damage: Report of 27 adult cases / 中华器官移植杂志

Objective To study long-term post-liver-transplantation hyperuricemia (HUA) and the influence of urate-lowering therapyon renal functions of adult patients.Methods Among 428 cases undergoing liver transplantations during March 2011 to December 2013,206 patients,whose followup periods were above 1 year,were selected as the objects of study.Those whose two-time serum uric acid (SUA) levels tested not in the same day one year after operation ＞420 μmol/L (male),or female ＞360 μmol/L (female) were divided into HUA group,and non-HUA group.The serum creatinine (SCr) concentrations and glomerular filtration rate (eGFR) were analyzedin the two groups at their peak SUA to find whether there was any difference between the two groups.Meanwhile,27 HUA patients with abnormal renal function were given urate-lowering therapy and the differences in SCr and eGFR after the therapy were observed.Results 49.5％ patients sufferedlong-term HUA after liver transplantations.As compared with non-HUA group,SCrconcentrations were increased statistically (P＜0.05),and eGFR was reduced statistically in HUA group (P＜0.05).After 8-week uratelowering therapy among 27 patients,SUA level in 24 cases (88.9％,24/27) returned to the normal standard and SCr concentrations in 21 cases (77.8％,21/27) decreased for a certain degree.SUA levels were decreased to (349.93 ± 22.85)μmol/L from (532.94 ± 93.91) μmol/L (P＜0.001).SCr concentrations were decreased to (129.52 ± 19.06)μmol/L from (144.95 ± 13.51) μmol/L (P =0.016).The eGFR increased to (56.30 ± 11.46) ml · min-1 · 1.73 m-2 from (46.46 ± 8.11) ml·min-1 ·1.73 m-2(P =0.012),which showed a certain degree of improvement in their renal functions.Conclusion HUA is a long-term common complication in liver transplanted adult patients,which has a negative influence on patients' renal functions,so we need to pay enough attention to this.Urate-lowing therapy has a positive influence on the improvement of renal function if other factors were excluded from the treatment.
