[X-ray evaluation of pulp calcification in adult permanent teeth after pulpotomy].

OBJECTIVE: To compare the clinical effects of pulpotomy with two kinds of calcium silicate materials, and to evaluate the formation of dentin bridge and pulp calcification after pulpotomy of adult permanent teeth. METHODS: Patients who visited the General Department of Peking University School and Hospital of Stomatology from November 2017 to September 2019 and planned for pulpotomy on permanent premolars and molars with carious exposed pulp were selected. They were randomly divided into two groups. Bioceramic putty material iRoot BP (iRoot group, n=22) and mineral trioxide aggregate MTA (MTA group, n=21) were used as pulp capping agents, respectively. The patients were recalled after one year and two years. The clinical efficacy, dentin bridge index (DBI) and pulp calcification index (PCI) were recorded. Blinding method was used for the patients and evaluators. RESULTS: There was no significant difference in gender, mean age, dentition and tooth position between the two groups (P>0.05). Seven cases were lost during the first year (4 cases in iRoot group and 3 cases in MTA group). In the iRoot group, 1 case had transient sensitivity at the time of 1-year follow-up. The cure rate of the two groups was 100% at the time of 2-year follow-up. The proportion of dentin bridge formation was 38.9% one year after operation, 55.6% two years after operation. The proportion of partial or even complete disappearance of root canal image was 5.6% before operation, 38.9% and 55.6% one and two years after operation, respectively. The difference was statistically significant by rank sum test (P < 0.05). There was no significant difference in dentin bridge formation and pulp calcification between the two groups (P < 0.05). DBI and PCI after operation was as the same as those before operation (44.4% cases of DBI and 25% cases of PCI) or gradually increased (55.6% cases of DBI and 75% cases of PCI). Spearman's nonparametric correlation analysis showed that age was positively correlated with preoperative pulp calcification index (PCI0, P < 0.05), but not with the dentin bridge index (DBI1, DBI2), pulp calcification index (PCI1, PCI2) and the degree of change (DBI2 vs. DBI1, PCI1 vs. PCI0, PCI2 vs. PCI0) 1-year and 2-year after operation (P>0.05). CONCLUSION: According to this study, good clinical effects were obtained within 2-year after pulpotomy of adult permanent teeth with MTA and iRoot. In some cases, the root canal system had a tendency of calcification aggravation, and there was no statistical difference in the development of this trend between the two groups.

[Efficacy and safety of superpulse thulium laser lithotripsy in the intracavitary treatment of urinary calculi].

Objective: To evaluate the efficacy and safety of superpulse thulium laser lithotripsy in the intracavitary treatment of urinary calculi. Methods: From May 2021 to July 2022, patients diagnosed with urinary calculi were screened in four medical centers. Those who met the criteria were treated with superpulse thulium fiber laser under endoscope. The patients' perioperative conditions were recorded. The main effective index was stone-free rate (SFR) 4 weeks after operation, the main safety index was the failure rate of the experimental instruments during operation, and the secondary safety index was the incidence rate of perioperative complications. Results: A total of 76 eligible patients completed superpulse thulium fiber laser lithotripsy, with an average age of (52.0±11.1) years, 54 males and 22 females. There were 31 renal stones, 43 ureteral stones and 2 bladder stones. Percutaneous nephrolithotomy was performed in 17 patients. Ureteroscopy lithotripsy/flexible ureteroscopy lithotripsy was performed in 57 patients and transurethral bladder lithotripsy was in 2 patients. The lithotripsy time of all patients was (50.9±31.4) minutes. There was no failure of experimental instruments during the operation. Six patients refused follow-up examination after operation. The incidence of postoperative adverse events was 61.8% (47/76). One patient needed hospitalization due to inguinal hernia after operation, and the rest were classified as Clavien-dindo grade 1-2. The SFR was 94.3% (66/70) at 4 weeks after operation. Conclusion: It is effective and safe to use superpulse thulium fiber laser in the treatment of urinary calculi.

[Progress and prospect of clinical application of anti-rabies virus monoclonal antibody preparation].

Rabies is a severe infectious disease caused by the rabies virus, which seriously damages the central nervous system. Once it occurs, the fatality rate is close to 100%. The World Health Organization's position paper on rabies vaccines recognizes that rabies immunoglobulin (RIG) should be used for post-exposure prophylaxis (PEP) in all category Ⅲ exposure for the first time, as well as in category Ⅱ exposure that suffer from severe immune deficiency, long-term massive use of immunosuppressants, and head and face exposure. The anti-rabies virus monoclonal antibody has high purity and specific activity, can be produced on a sustainable scale, and has no risk of blood source virus contamination. Preclinical pharmacodynamic studies and clinical trial results of the anti-rabies virus monoclonal antibody preparation have confirmed that the preparation has a broad-spectrum neutralization effect on the rabies virus. Additionally, its combined application with the vaccine has little impact on the active immunity of the vaccine. Therefore, the anti-rabies virus monoclonal antibody preparation shows great potential for clinical application in PEP.

[Endovascular therapy accompanied by spontaneous portosystemic shunts for overt hepatic encephalopathy].

Objective: To preliminarily evaluate the safety and efficacy of shunt-related interventional therapy accompanied with spontaneous portosystemic shunts (SPSS) in patients with hepatic encephalopathy (HE). Methods: Case data on six patients who underwent interventional therapy accompanied by SPSS for HE from January 2017 to March 2021 were collected to evaluate the efficacy and postoperative complications. Results: All six patients underwent SPSS. Four patients had hepatitis B cirrhosis; one had alcoholic cirrhosis; and one had hepatic arterioportal fistula-induced portal hypertension. Child-Pugh liver function scores were C and B in three and three cases, respectively. The SPSS type was gastrorenal shunt in two cases; portal-thoracic-azygos venous in two cases; portal-umbilical-iliac venous in one case; and portal-splenic venous - inferior vena cava in one case. Two of them had previously had a transjugular intrahepatic portosystemic shunt (TIPS), and there were SPSS prior to TIPS. Five cases (5/6) successfully underwent shunt embolization, and one case (1/6) underwent stent implantation for flow restriction (portal-umbilical-iliac vein). The technical success rate was 100%. HE did not recur during hospitalization or the three-month follow-up period. However, one case had a recurrence of HE within a year after surgery and was treated symptomatically, while another experienced gastrointestinal bleeding a year after surgery.. Conclusion: SPSS embolization or flow restriction is effective and safe for improving HE patients' symptoms.

[Multicenter real world study on the efficacy and safety of eribulin for the treatment of advanced breast cancer].

Objective: To explore the efficacy and safety of real-world eribulin in the treatment of metastatic breast cancer. Methods: From December 2019 to December 2020, patients with advanced breast cancer were selected from Beijing Chaoyang District Sanhuan Cancer Hospital, Shandong Cancer Hospital, Peking University Cancer Hospital, Baotou Cancer Hospital, Shengjing Hospital Affiliated to China Medical University, and Cancer Hospital of Chinese Academy of Medical Sciences. Kaplan-Meier method and Log rank test were used for survival analysis, and Cox regression model was used for multivariate analysis. Results: The median progression-free survival (PFS) of 77 patients was 5 months, the objective response rate (ORR) was 33.8%, and the disease control rate (DCR) was 71.4%. The ORR of patients with triple-negative breast cancer was 23.1%, and the DCR was 57.7%; the ORR of patients with Luminal breast cancer was 40.0%, and the DCR was 77.8%; the ORR of patients with HER-2 overexpression breast cancer was 33.3%, and the DCR was 83.3%. ORR of 50.0% and DCR of 66.7% for patients treated with eribulin as first to second line treatment, ORR of 29.4% and DCR of 76.5% for patients treated with third to fourth line and ORR of 28.6% and DCR of 71.4% for patients treated with five to eleven line. The ORR of patients in the eribulin monotherapy group was 40.0% and the DCR was 66.0%; the ORR of patients in the combination chemotherapy or targeted therapy group was 22.2% and the DCR was 81.5%. Patients with a history of treatment with paclitaxel, docetaxel, or albumin paclitaxel during the adjuvant phase or after recurrent metastasis had an ORR of 32.9% and a DCR of 69.9% when treated with eribulin. The treatment efficacy is an independent prognostic factor affecting patient survival (P<0.001). The main adverse reactions in the whole group of patients were Grade Ⅲ-Ⅳ neutrophil decline [29.9% (23/77)], and other adverse reactions were Grade Ⅲ-Ⅳ fatigue [5.2% (4/77)], Grade Ⅲ-Ⅳ peripheral nerve abnormality [2.6% (2/77)] and Grade Ⅲ-Ⅳ alopecia [2.6% (2/77)]. Conclusions: Eribulin still has good antitumor activity against various molecular subtypes of breast cancer and advanced breast cancer that has failed multiple lines of chemotherapy, and the adverse effects can be controlled, so it has a good clinical application value.

[Evaluation of bioceramic putty repairmen iRoot and mineral trioxide aggregate in mature permanent teeth pulpotomy].

OBJECTIVE: To evaluate the clinical characteristics and effectiveness of pulpotomy in mature permanent teeth with bioceramic putty repairmen iRoot and mineral trioxide aggregate (MTA). METHODS: Pulpotomy was performed on mature permanent premolars and molars with carious exposures at the Department of General Dentistry of Peking University School and Hospital of Stomatology, from November 2017 to September 2019. The patients were randomly divided into 2 groups, Group iRoot (n=22) and Group MTA (n=21). In Group iRoot, bioceramic putty repairmen iRoot was used as pulp capping agent, while in Group MTA, mineral trioxide aggregate was used as pulp capping agent. All the patients had signed informed consent forms. The clinical efficacy was evaluated by clinical examinations (temperature and electrical activity test) and imaging examinations 3, 6, and 12 months after surgery. Blinding was used for the patients and evaluators, but due to the obvious differences in the properties of the two pulp capping agents, the blinding method was not used for the treatment provider (the attending physician). RESULTS: There was no significant difference in gender, average age, dentition and tooth position distribution between the two groups (P>0.05). In the study, 7 cases were lost to follow-up 12 months after operation (4 cases in Group iRoot, and 3 cases in Group MTA). One case in each of the two groups had transient sensitivity at the end of the 3-month follow-up, and the pulp vitality was normal at the end of the 6-month follow-up. One case in Group iRoot showed sensitivity at the end of the 12-month follow-up. The success rates of the two groups at the end of 12-month follow-up were 100%, and the cure rates were 94.4% (Group iRoot) and 100% (Group MTA), respectively, and the difference was not statistically significant (P>0.05). No cases in Group iRoot had obvious crown discoloration, while 3 cases in Group MTA had. CONCLUSION: The clinical characteristics and effectiveness of pulpotomy in mature permanent teeth with bioceramic putty repairmen iRoot were similar with MTA. Bioceramic putty repairmen iRoot is an acceptable material when used in pulpotomy of mature permanent teeth. Because it is not easy to cause tooth discoloration after treatment and is convenient to operate, bioceramic putty repairmen iRoot has a better clinical application prospect.

Efficacy of erector spinae plane block for analgesia in breast surgery: a systematic review and meta-analysis.

The erector spinae plane block is a new regional anaesthesia technique that provides truncal anaesthesia for breast surgery. This systematic review and meta-analysis was undertaken to determine if the erector spinae plane block is effective at reducing pain scores and opioid consumption after breast surgery. This study also evaluated the outcomes of erector spinae plane blocks compared with other regional blocks. PubMed, Embase, Scopus, the Cochrane Central Register of Controlled Trials and ClinicalTrials.gov were searched. We included randomised controlled trials reporting the use of the erector spinae plane block in adult breast surgery. Risk of bias was assessed with the revised Cochrane risk-of-bias tool. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework was used to assess trial quality. Thirteen randomised controlled trials (861 patients; 418 erector spinae plane block, 215 no blocks, 228 other blocks) were included. Erector spinae plane block reduced postoperative pain compared with no block: at 0-2 hours (mean difference (95% CI) -1.63 (-2.97 to -0.29), 6 studies, 329 patients, high-quality evidence, I2  = 98%, p = 0.02); at 6 hours (mean difference (95% CI) -0.90 (-1.49 to -0.30), 5 studies, 250 patients, high-quality evidence, I2  = 91%, p = 0.003); at 12 hours (mean difference (95% CI) -0.46 (-0.67 to -0.25), 5 studies, 250 patients, high-quality evidence, I2  = 58%, p < 0.0001); and at 24 hours (mean difference (95% CI) -0.50 (-0.70 to -0.30), 6 studies, 329 patients, high-quality evidence, I2  = 76%, p < 0.00001). Compared with no block, erector spinae plane block also showed significantly lower postoperative oral morphine equivalent requirements (mean difference (95% CI) -21.55mg (-32.57 to -10.52), 7 studies, 429 patients, high-quality evidence, I2  = 99%, p = 0.0001). Separate analysis of studies comparing erector spinae plane block with pectoralis nerve block and paravertebral block showed that its analgesic efficacy was inferior to pectoralis nerve block and similar to paravertebral block. The incidence of pneumothorax was 2.6% in the paravertebral block group; there were no reports of complications of the other blocks. This review has shown that the erector spinae plane block is more effective at reducing postoperative opioid consumption and pain scores up to 24 hours compared with general anaesthesia alone. However, it was inferior to the pectoralis nerve block and its efficacy was similar to paravertebral block. Further evidence, preferably from properly blinded trials, is required to confirm these findings.

[Management of complex renal stones by a novel ureterorenoscope with vacuum suctioning system combined with flexible ureteroscope].

Objective: To evaluate the feasibility and safety of Sotn ureterorenoscope combined with flexible ureteroscope on managing complex renal stones. Methods: Patients treated with the Sotn ureterorenoscope combined with flexible ureteroscope between January 2010 and December 2019 were employed from the Sun Yat-sen Memorial Hospital of Sun Yat-sen University and Jiangmen Wuyi Traditional Chinese Medicine Hospital. The patients' information of age, gender, comorbidities, stone characteristics (stone size, hounsfield units, stone composition, stone location, etc.), operative time and console time, stone-free rate (SFR), and perioperative complication rate were collected. The primary outcome was defined as primary SFR in 1 month of operation, and the secondary outcome was the perioperative complication rate. The differences in preoperative and postoperative data between patients with different kinds of stones were compared. Results: A total of 347 patients were included in the study, with 220 males and 127 females. The age [M(Q1,Q3)] was 51 (42, 58) years. There were 94 patients suffered from multiple renal stones and 253 patients with staghorn renal stones. The operative time and console time age [M(Q1,Q3)] for all patients were 87 (55, 115) min and 59 (27, 75) min, respectively. The primary SFR was 81.3% [83.8% for multiple renal stones and 74.5% for staghorn renal stones (P=0.048)]. Complications occurred in 80 patients (23.1%), of which 79 cases were classified as Clavien-Dindo grade 1-2, and 1 case (0.3%) was grade 3-4. For patients with multiple renal stone, compared with the residual stone group, the complete stone-free group had smaller stone size [15.5 (12.0, 21.0) vs 22.0 (17.5, 28.1) mm, P<0.001], and lower hounsfield units [920.0 (658.0, 1 172.5) vs 1 125.0 (944.9, 1 247.5), P=0.022]. Patients with complications had longer operative time than those without complications [60.0 (38.5, 90.0) vs 75.0 (51.3, 110.0) min, P=0.022]. The SFR was higher in patients with stones size ≤ 20 mm compared to those with stones size > 20 mm (91.8% vs 67.5%, P<0.001), while the difference in complication rate was not statistically significant (P>0.05). In the staghorn renal stones group, compared with the residual stone group, the complete stone-free group had smaller stone size [35.0 (25.8, 45.3) vs 53.5 (39.3, 67.5) mm, P<0.001]. Patients with complications had larger stone size than those without complications [43.5 (34.8, 56.5) vs 36.0 (27.0, 50.0) mm, P=0.007]. Patients with stone size ≤ 40 mm had higher SFR (87.5% vs 55.3%, P<0.001) and lower complication rate(10.7% vs 31.6%, P=0.012) compared to those with stone size >40 mm. Conclusion: Sotn ureterorenoscope combined with flexible ureteroscope is an effective and safe choice for the treatment of complex renal calculi.

[The variation of serum uric acid levels among patients with myocardial infarction treated with ticagrelor and the association between serum uric acid and platelet reactivity].

Objectives: To compare the impact of ticagrelor or clopidogrel on serum uric acid levels among patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) and further evaluate the effects of variation of serum uric acid levels on platelet reactivity. Methods: STEMI patients who admitted to Fuwai Hospital from April 2017 to January 2020, and underwent primary PCI and discharged alive with aspirin and ticagrelor or clopidogrel were included in this study. Patients were divided into ticagrelor group and clopidogrel group. The baseline clinical data were collected. Serum uric acid and creatinine levels at baseline and 30 days post-PCI were measured. Light transmittance aggregometry was used to assess maximum aggregation rate induced by adenosine diphosphate and arachidonic acid. The changes of serum uric acid and creatinine were compared between the two groups. Multivariate logistic regression was performed to evaluate independent related factors for rise in the uric acid levels, and the effect of variation of serum uric acid level on platelet reactivity was analyzed. Results: A total of 967 patients were included, the age was (59.4±12.1) years, and 163 case were female. There were 550 cases in ticagrelor group (56.9%) and 417 cases in clopidogrel group (43.1%). Baseline serum uric acid and creatinine levels were similar between the 2 groups. At 30 days, the serum uric acid level [(347.2±96.5) mmol/L vs. (341.2±105.3) mmol/L, P=0.009] and absolute [46.4 (-2.4, 88.1) mmol/L vs. 25.0 (-21.9, 73.0) mmol/L, P=0.001] and percentage [13.2 (-0.01, 29.0) % vs. 7.9 (-5.7, 25.0) %, P=0.007] increase in the serum uric acid levels were significantly higher in ticagrelor group than in clopidogrel group. The level of serum creatinine at 30 days was significantly lower in ticagrelor group than in clopidogrel group [(89.7±21.3) µmol/L vs. (94.4±43.9) µmol/L, P<0.05], whereas there were no differences in absolute [8.0 (-1.4, 16.6) µmol/L vs. 7.8 (-2.0, 16.6) µmol/L] and percentage [10.5 (-1.7%, 22.6%) vs. 9.8 (-2.4%, 22.1%)] change in the serum creatinine between the 2 groups (all P>0.05). Logistic regression analysis showed that, after adjusting for confounding factors, ticagrelor therapy was an independent related factor of serum uric acid elevation (OR=1.582, 95% CI:1.023-2.447, P=0.039). The variation of the serum uric acid levels did not affect platelet aggregation and the percentage of high platelet reactivity in both groups. Conclusions: Ticagrelor use is related to a significant increase in the serum uric acid levels at 30 days post-PCI in this patient cohort. The variations in the uric acid levels do not increase the percentage of high platelet reactivity in STEMI patients treated with ticagrelor or clopidogrel.

Communicable disease among people experiencing homelessness in California.

California has a large population of people experiencing homelessness (PEH) that is characterised by a high proportion of people who are unsheltered and chronically homeless. PEH are at increased risk of communicable diseases due to multiple, intersecting factors, including increased exposures, comorbid conditions including substance use disorder and mental illness and lack of access to hygiene and healthcare facilities. Data available for several communicable diseases show that PEH in California experiences an increased burden of communicable diseases compared to people not experiencing homelessness. Public health agencies face unique challenges in serving this population. Efforts to reduce homelessness, increase access to health care for PEH, enhance data availability and strengthen partnerships among agencies serving PEH can help reduce the disparity in communicable disease burden faced by PEH.

[Comparison of myotomy and coronary artery bypass grafting in surgical treatment of symptomatic left anterior descending myocardial bridges].

Objective: To compare the effect of myotomy and coronary artery bypass grafting (CABG) to treat symptomatic myocardial bridges (MBs) of the left anterior descending artery (LAD). Methods: From January 2009 to December 2017, a total of 54 eligible patients [34 males, 20 females, with a median age of 60 (51, 64) years old] with symptomatic MBs of LAD who underwent myotomy (31 patients) or CABG (23 patients) at the Department of Cardiovascular Surgery of Zhongshan Hospital, Fudan University were included in the study. Surgical effect of the two groups were compared and multivariate logistic regression models were used to analyze the risk factors of major adverse cardiac events (MACE). Results: No significant differences between the two groups were observed with respect to age, gender, risk factors of coronary artery disease (CAD), symptoms, angiographic findings of MBs and preoperative cardiac status, and 0 surgery-associated death was observed. Among the 31 myotomy patients, 4 patients underwent off-pump myotomy (including one patient who underwent urgent conversion from off-pump to on-pump surgery due to massive hemorrhaging secondary to the right ventricular perforation), and the remaining 27 cases received myotomy under cardiopulmonary bypass with cardiac arrest. All 23 bypass surgery patients underwent off-pump CABG surgery with in situ left internal mammary artery (LIMA) grafting to the distal LAD. After LIMA grafting, the median graft flow was 14 (11, 20) ml/min. During a median follow-up of 26 months, 11 patients developed MACEs (7.4% for myotomy vs 40.9% for bypass surgery, P=0.007). Surgical strategy (CABG surgery vs myotomy) was an independent risk factor for MACE (OR=3.681, 95% CI: 1.812-8.685, P=0.011). Compared with myotomy, CABG surgery had a significantly higher incidence of adverse angiographic results (3.7% of residual compression vs 40.9% of LIMA graft failure, P=0.003). Among 10 CABG surgery patients with LAD-MBs and proximal coronary obstruction, all LIMA grafts were patent, though one case reported recurrent angina pectoris 2 years after the surgery which was relieved after drug therapy. Conclusions: For patients with symtomatic LAD-MBs, myotomy may be associated with favorable mid-term outcomes and angiographic results. However, CABG surgery should be recommended for those with concomitant proximal obstruction of LAD.

[Research progress of terlipressin in the treatment of cirrhotic ascites-related complications].

Ascites is the most common clinical symptom in the decompensated stage of patients with liver cirrhosis, and its co-existence in complex conditions, such as refractory ascites, hyponatremia, hepatorenal syndrome and other complications may harm seriously. Splanchnic vasodilation is the key pathological link of cirrhotic ascites-related complications and the treatment of this link can help to eliminate the symptoms of ascites and prevent the further deterioration of decompensated cirrhosis. This paper summaries the pharmacological basis, clinical evidence and application characteristics of a vasocative drugs-terlipressin in the treatment of cirrhotic ascites-related complications, and further analyzes the problems existing in the current research, then proposes a prospect.

[Observation of the therapeutic and characteristic effects of terlipressin on refractory cirrhotic ascites].

Objective: To observe the therapeutic effect of terlipressin on refractory ascites (RA) in cirrhosis, and its role and impact on acute kidney injury (AKI). Methods: A non-randomized controlled clinical trial data of 111 hospitalized cases of liver cirrhosis accompanied with RA was collected from Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine, Zhongshan Hospital of Hubei Province, The First Affiliated Hospital of Zhengzhou University, The First Affiliated Hospital of Medical School of Zhejiang University, and People's Hospital of Pudong New Area of Shanghai between March 2015 and March 2017. 26 cases of conventional treatment group (control group) were divided into two subgroups: RA without AKI (RA-NAKI) and RA with AKI (RA-AKI), and each subgroup consisted 13 cases. Patients with bacterial infection were treated with diuretics, albumin supplementation and antibiotics. 85 cases were presented in terlipressin combined treatment group, of which 27 cases were of RA-NAKI and 58 cases were of RA-AKI. Control group was injected terlipressin 1mg of intravenous drip or static push (once q6 h ~ 12 h) for more than 5 days. The treatment duration lasted for 2 weeks with 4 weeks of follow-up. Body weight, 24-hour urine volume, abdominal circumference, mean arterial pressure (MAP), liver and kidney function, anterior hepatic ascites, deepest point of ascites, and ultrasonographic detection of ascites in supine position before treatment, one and two weeks after treatment and 4 weeks after follow-up were compared. Count data were tested by χ (2). Samples of four groups at baseline were compared. One-way analysis of variance was used for normal distribution data and Kruskal-Wallis H test for non-normal distribution data. Repeated measures analysis of variance was used to compare the difference in efficacy between different time points before and after treatment in the group. The LSD method of one-way ANOVA was used to compare the two groups. A t-test of independent samples was used to compare the efficacy of different time series between the two groups. Mann-Whitney rank- sum test was used to compare the data of non-normal distribution between the two groups. Results: (1) Baseline data were compared among 4 subgroups of terlipressin RA-NAKI and control RA-AKI. Control group age was higher than that of terlipressin group, and the serum creatinine (SCr) of the RA-AKI group was higher than RA-NAKI group, and there was no significant difference in the rest of the baseline data and the combined medication (P > 0.05). (2) An intra-group comparison between control and trelipressin before and after treatment showed that all patients had lower body mass, abdominal circumference and deepest ascites, and higher serum albumin (P < 0.05). 24-hour urine volume and MAP was significantly increased in the terlipressin group, while the pre-ascites, SCr and child Turcotte Pugh (CTP) scores were decreased. Body weight, abdominal circumference, pre-ascites, and deepest ascites of the terlipressin group were decreased, while MAP was increased during the treatment and follow-up periods. The differences were statistically significant when compared with the control group at the same time (P < 0.05). There was a statistically significant difference in the increase of 24-h urine volume in the terlipressin group compared with the control group (P < 0.05). The decrease in SCr and CTP in the terlipressin group after 2 weeks of treatment and 4 weeks of follow-up was statistically significant compared with the control group (P < 0.05). (3) Among the two subgroups of RA-AKI and RA-NAKI in the terlipressin group, the baseline SCr value of the former was higher than that of the latter. After treatment, the body weight, abdominal circumference, pre-ascites, deepest ascites and CTP scores were decreased. In the RA-AKI group, 24-hour urine volume, MAP, SCr and serum albumin concentration were significantly increased. The difference between the two subgroups before and after treatment was compared, and the body weight of RA-AKI group at 1, 2 weeks of treatment and 4 weeks of follow-up was significantly lower than RA-NAKI group, which were (- 2.3 ± 0.2 vs. - 1.5 ± 0.2) kg, (- 4.1 ± 0.2 vs. - 2.6 ± 0.2) kg, (- 4.2 ± 0.3 vs. - 2.4 ± 0.3) kg, respectively. RA-NAKI group urine volume was significantly increased at 2 weeks of treatment and 4 weeks of follow-up, which was (468 ± 42 vs. 110 ± 131) ml, (272 ± 34 ml vs. 11 ± 112) ml, respectively. SCr reduction (18.3 ± 4.7 vs. 0.9 ± 2.4) µmol/l at 4 weeks of follow-up was apparent in RA-NAKI group, and the difference was statistically significant (P < 0.05). Conclusion: Addition of terlipressin to conventional treatment may significantly increase MAP, 24-h urine volume, improve renal function and promote ascites resolution in patients with refractory cirrhotic ascites. Moreover, its combination effect is more obvious in AKI patients, and adverse reactions are mild.

[The hearing self-protection behavior and internal factors of workers exposured to occupational noise].

Objective: To analyze the hearing self-protection behavior patterns and internal factors of workers exposured to occupational noise in an aircraft manufacturing industry based on health belief model, so as to provide reference for further health promotion programs and intervention measures. Methods: A total of 1600 front-line workers were selected from 10 units of an aircraft manufacturing enterprise by cluster sampling method. The basic and occupational information of employees were collected, and a self-reported questionnaire was designed according to the health belief model to acquire the hearing self-protection behaviors of workers. Results: There were significant differences in the perceived severity, perceived benefit, perceived impairment, self-efficacy and behavioral incentive scores of different hearing self-protection behaviors among the noise-causing workers (P<0.05). There were significant differences in the distribution of hearing self-protection behaviors among different genders, ages, education levels, length of service, initial noise exposure time and cumulative noise reception time (P<0.05). The perceived benefits, perceived barriers, behavioral incentives, self-efficacy scores, and educational attainment of the noise-causing workers were all related to the type of hearing self-protection behavior (P<0.05) . Conclusion: The educational level and health belief model can predict the hearing self-protection behavior patterns of front-line workers to some extent, more attention should be paid to the monitoring of the well-educated employees.

[The efficacy of immunoadsorption with Infliximab theraepy on the modulation of disease activity in patients with severe rheumatoid arthritis].

Objective: To evaluated the efficacy of additional immunoadsorption therapy (2 times) besides infliximab (IFX) ondisease remission in patients with severe rheumatoid arthritis (RA). Methods: 90 patients with serve RA were included in this study.There were 43 patients in the control group who were treated with IFX 3 mg/kg+ methotrexate (MTX) therapy, and other 47 patients were experimental group, who were previous given 2 times additional immunoadsorption therapy before IFX 3 mg/kg+ MTX therapy.IFX 3 mg/kg was infused at weeks 0, 2, 6, 14, 22 and 30.Age, sex ration, mean disease duration and core index of disease activity in two treatment groups were collected at weeks 0, 2, 6 and 30 weeks to compare the efficacy and safety of combined immunosorbent therapy in the treatment of severe RA. Results: The baseline age, sex ration and core indexes of disease activity were comparable between the two treatment groups (P>0.05). After treatment, the core indexes of disease activity of all patients decreased significantly compared with their baseline levels (P<0.05) and the difference of sustainable maintenance to 30 weeks (P<0.05). After 2 and 6 weeks of treatment, patients' ACR20 remission rates of the experimental group were 46.81% and 68.08%, significantly higher than the control group; after 30 weeks of treatment, patients' ACR20 remission rates of the experimental group was more than 90%, while the number was 79.07% in the control group.At the same time DAS28-ESR clinical remission and low disease activity also reached 72.34% in the experimental group, higher than the control group(P<0.05). Conclusion: Additional immunoadsorption therapy can rapid relive the disease activity of serve RA patients, and the remission rate of 30W was significantly higher than only IFX treatment.

[Contemporary use of ticagrelor in patients with acute coronary syndrome after discharge].

Objective: To investigate the degree and determinants of using ticagrelor among discharged patients with acute coronary syndrome (ACS). Methods: Patients with ACS in Fuwai hospital who were given ticagrelor after discharge between Jan. 2015 to Jun. 2015 were analyzed.The clinical characteristics and adherence to ticagrelor of these patients were collected by reviewing the electronic medical records and telephone interview.Date were statistically-analyzed. Results: Among all screened 404 patients, 158 (39.1%) patients prematurely stopped ticagrelor within 12 months, while 119(29.5%) patients switched from ticagrelor to clopidogrel.Unavailable locally (34.8%), economic reasons (17.7%) and hemorrhagic events (18.4%) were the main causes of the premature discontinuation of ticagrelor.Univariate analysis showed left main disease (P=0.04) and the frequency of outpatient follow-up (P<0.01) as relative factors for prematurely stopping ticagrelor outside hospital after discharge.Multivariate analysis revealed medical insurance payment (OR 1.79, 95%CI 1.03-3.11) and the frequency of outpatient follow-up (OR 0.61, 95%CI 0.43-0.86) as independent predictors of prematurely stopping ticagrelor outside hospital.Prematurely stopping ticagrelor has no significant effect on the ischemic events (myocardial infaction or stroke) (P=0.76). Conclusion: Social cinditions is the main factor for the persistence to ticagrelor among ACS patients after dischcrge.Medical insurance payment and low frequency of outpatient follow-up were independent predictors of prematurely stopping ticagrelor and it may not have impact on ischemic events.

A break-even analysis for dementia care collaboration: Partners in Dementia Care.

BACKGROUND: Dementia is a costly disease. People with dementia, their families, and their friends are affected on personal, emotional, and financial levels. Prior work has shown that the "Partners in Dementia Care" (PDC) intervention addresses unmet needs and improves psychosocial outcomes and satisfaction with care. OBJECTIVE: We examined whether PDC reduced direct Veterans Health Administration (VHA) health care costs compared with usual care. DESIGN: This study was a cost analysis of the PDC intervention in a 30-month trial involving five VHA medical centers. PARTICIPANTS: Study subjects were veterans (N = 434) 50 years of age and older with dementia and their caregivers at two intervention (N = 269) and three comparison sites (N = 165). INTERVENTIONS: PDC is a telephone-based care coordination and support service for veterans with dementia and their caregivers, delivered through partnerships between VHA medical centers and local Alzheimer's Association chapters. MAIN MEASURES: We tested for differences in total VHA health care costs, including hospital, emergency department, nursing home, outpatient, and pharmacy costs, as well as program costs for intervention participants. Covariates included caregiver reports of veterans' cognitive impairment, behavior problems, and personal care dependencies. We used linear mixed model regression to model change in log total cost post-baseline over a 1-year follow-up period. KEY RESULTS: Intervention participants showed higher VHA costs than usual-care participants both before and after the intervention but did not differ significantly regarding change in log costs from pre- to post-baseline periods. Pre-baseline log cost (p ≤ 0.001), baseline cognitive impairment (p ≤ 0.05), number of personal care dependencies (p ≤ 0.01), and VA service priority (p ≤ 0.01) all predicted change in log total cost. CONCLUSIONS: These analyses show that PDC meets veterans' needs without significantly increasing VHA health care costs. PDC addresses the priority area of care coordination in the National Plan to Address Alzheimer's Disease, offering a low-cost, structured, protocol-driven, evidence-based method for effectively delivering care coordination.

Removable uterine compression sutures for postpartum haemorrhage.

In 1997, B-Lynch and colleagues introduced the B-Lynch uterine compression suture for postpartum haemorrhage. Since then, various uterine compression sutures have been used and postpartum hysterectomy has been avoided in many women. However, some complications have emerged in years. In this article we discuss two types of uterine compression sutures in which stitches can be removed. The procedures have been successfully applied with no problems and no observed complications to date. This is a novel concept, with the potential to reduce morbidity related to compression sutures, but needs further evaluation.

Efficacy of percutaneous radiofrequency ablation for the treatment of hepatocellular carcinoma.

In this study, we sought to evaluate the efficacy of transcatheter arterial chemoembolization (TACE) plus radiofrequency ablation (RFA; experimental group) versus RFA treatment (control group) in patients receiving palliative treatment for hepatocellular carcinoma. To summarize the available evidence, we used the Review Manager 5.1 software to perform a meta-analysis of English-language articles published in public databases prior to 2014. Based on 6 studies that met the inclusion criteria, a total of 531 (experimental group, 272; control group, 259) patients with hepatocellular carcinoma were included in the meta-analysis. The meta-analysis demonstrated that the experimental group had a higher 3-year survival rate [risk ratios (RRs) = 1.41; 95% confidence interval (CI) = 1.03-1.94; P < 0.05] and a higher 2-year survival rate (RR = 1.11; 95%CI = 1.01-1.23; P < 0.05) than the control group. In the overall meta-analysis, the overall RRs were 2.02 (95%CI = 1.40-2.91; P < 0.05) and 1.63 (95%CI = 1.06-2.51; P < 0.05) for 3- and 5-year recurrence-free survival, respectively. Furthermore, the overall meta-analysis showed an overall RR of 0.75 (95%CI = 0.60-0.93; P < 0.05) for the incidence of tumor progression and an overall RR of 1.19 (95%CI = 0.33-4.33; P > 0.05) for the major complication rate. In a sensitivity analysis, the above mentioned meta-analytic estimates were unchanged by the removal of 1 study at a time. The meta-analysis suggested that the experimental group had a higher survival rate, a higher recurrence-free survival rate, and a lower incidence of tumor progression than the corresponding control group.
