Small molecule inhibitors of RORγt for Th17 regulation in inflammatory and autoimmune diseases / 药物分析学报

As a ligand-dependent transcription factor,retinoid-associated orphan receptor γt(RORyt)that controls T helper(Th)17 cell differentiation and interleukin(IL)-17 expression plays a critical role in the pro-gression of several inflammatory and autoimmune conditions.An emerging novel approach to the therapy of these diseases thus involves controlling the transcriptional capacity of RORyt to decrease Th17 cell development and IL-17 production.Several RORyt inhibitors including both antagonists and inverse agonists have been discovered to regulate the transcriptional activity of RORyt by binding to orthosteric-or allosteric-binding sites in the ligand-binding domain.Some of small-molecule inhibitors have entered clinical evaluations.Therefore,in current review,the role of RORyt in Th17 regulation and Th17-related inflammatory and autoimmune diseases was highlighted.Notably,the recently developed RORyt inhibitors were summarized,with an emphasis on their optimization from lead compounds,ef-ficacy,toxicity,mechanisms of action,and clinical trials.The limitations of current development in this area were also discussed to facilitate future research.

Chinese herbal medicines for treating ulcerative colitis via regulating gut microbiota-intestinal immunity axis / 中草药·英文版

Ulcerative colitis (UC) is one of types of inflammatory bowel disease with high recurrence. Recent studies have highlighted that microbial dysbiosis as well as abnormal gut immunity are crucial factors that initiate a series of inflammatory responses in the UC. Modulating the gut microbiota-intestinal immunity loop has been suggested as one of key strategies for relieving UC. Many Chinese herbal medicines including some of single herb, herbal formulas and the derived constituents have been reported with protective effect against UC through modulating gut microbiome and intestinal immunity. Some clinical trials have shown promising results. This review thus focused on the current knowledge on using Chinese herbal medicines for treating UC from the mechanism aspects of regulating intestinal homeostasis involving microbiota and gut immunity. The existing clinical trials are also summarized.

Effect of posture on total hip arthroplasty through direct anterior approach / 中国骨伤

OBJECTIVE@#To investigate the effect of different postures on direct anterior approach(DAA) total hip arthroplasty.@*METHODS@#Total of 94 patients who underwent DAA total hip arthroplasty from July 2016 to June 2020 were retrospectively analyzed. They were divided into two groups according to different positions during the operation, including 45 cases in lateral position and 49 cases in supine position (with the aid of stent). The general data such as gender, affected limb, body mass index(BMI), incision length, operation time, intraoperative bleeding volume, drainage volume 24 hours after operation, hemoglobin difference before and after operation, first landing time after operation, postoperative hospitalization time, postoperative complications, visual analogue scale(VAS) at 1 day, 1, 2 weeks, 1, 3 and 6 months after operation, Harris score at 1, 2 weeks, 1, 3 and 6 months after operation were observed and compared between the two groups.@*RESULTS@#Patients in both groups were followed up for 6 to 12 months with an average of (8.31±2.22) months. There was no significant difference between two groups in gender, affected limb, age, height, weight, body mass index(BMI), preoperative VAS score and preoperative Harris score(P>0.05). The incision length, operation time, intraoperative bleeding volume, 24-hour drainage volume, hemoglobin difference before and after operation, first time to the ground and postoperative hospitalization time of patients in supine position (assisted by stent) group were all better than those in lateral position group(P<0.05);There was no significant difference in the number of blood transfusions during and after operation(P=0.550). There was no significant difference in anteversion angle and abduction angle in the supine position(with the aid of stent) group during and after operation (P=0.825, P=0.066);There was significant difference in anteversion angle and abduction angle in the lateral position group during and after operation(P<0.05). VAS of patients in supine position (assisted by stent) group were lower than those in lateral position group at 1 day, 1, 2 weeks and 1 month after operation(P<0.05), and there was no statistical difference between two groups at 3 and 6 months after operation(P>0.05). Harris scores of patients in supine position(assisted by stent) group were higher than those in lateral position group at 1 week, 1 month and 3 months after operation(P<0.05), and there was no significant difference between two groups at 6 months after operation(P>0.05).@*CONCLUSION@#Compared with the lateral position, the supine position DAA total hip arthroplasty has the advantages of small incision, short operation time, less bleeding, early landing time, short hospitalization time, and small intraoperative acetabular cup position judgment error. It has the advantage of fast postoperative recovery, but the recovery of hip joint function is the same after 6 months.

Erythropoietin promotes myocardial infarction repair in mice by improving the function of Sca-1+ stem cells / 生理学报

Myocardial infarction (MI) is one of the leading causes of death in the world. With the improvement of clinical therapy, the mortality of acute MI has been significantly reduced. However, as for the long-term impact of MI on cardiac remodeling and cardiac function, there is no effective prevention and treatment measures. Erythropoietin (EPO), a glycoprotein cytokine essential to hematopoiesis, has anti-apoptotic and pro-angiogenetic effects. Studies have shown that EPO plays a protective role in cardiomyocytes in cardiovascular diseases, such as cardiac ischemia injury and heart failure. EPO has been demonstrated to protect ischemic myocardium and improve MI repair by promoting the activation of cardiac progenitor cells (CPCs). This study aimed to investigate whether EPO can promote MI repair by enhancing the activity of stem cell antigen 1 positive stem cells (Sca-1+ SCs). Darbepoetin alpha (a long-acting EPO analog, EPOanlg) was injected into the border zone of MI in adult mice. Infarct size, cardiac remodeling and performance, cardiomyocyte apoptosis and microvessel density were measured. Lin- Sca-1+ SCs were isolated from neonatal and adult mouse hearts by magnetic sorting technology, and were used to identify the colony forming ability and the effect of EPO, respectively. The results showed that, compared to MI alone, EPOanlg reduced the infarct percentage, cardiomyocyte apoptosis ratio and left ventricular (LV) chamber dilatation, improved cardiac performance, and increased the numbers of coronary microvessels in vivo. In vitro, EPO increased the proliferation, migration and clone formation of Lin- Sca-1+ SCs likely via the EPO receptor and downstream STAT-5/p38 MAPK signaling pathways. These results suggest that EPO participates in the repair process of MI by activating Sca-1+ SCs.

Cross-sectional associations between reproductive lifespan duration and urinary albumin-creatinine ratio / 中华内科杂志

Objective:To investigate the association between reproductive lifespan duration (RLD) and urinary albumin-creatinine ratio (UACR) in a Chinese postmenopausal population.Methods:This cross-sectional study included 11 055 naturally postmenopausal women from seven regions of China from May to December 2011. RLD was divided into four groups. Propensity score matching was performed to reduce bias, and logistic regressions and stratifications were conducted to investigate the association between RLD and increased UACR (≥30 mg/g). Mediation effect analysis was performed to quantify the effect of RLD on cardiovascular disease (CVD) induced by elevated UACR.Results:There were 2 373 participants with a RLD of 18-31 years, 2 888 participants with a RLD of 32-34 years, 2 472 participants with a RLD of 35-36 years, and 3 322 participants with a RLD of 37-50 years. The shortest RLD (18-31 years) group was characterized with older age ( P<0.001), a higher incidence of CVD ( P=0.025), and the highest level of UACR ( P<0.001). After adjusting for confounders, women with a longer RLD (37-50 years group) exhibited a lower risk of UACR elevation compared with those with the shortest RLD (18-31 years group) ( OR=0.72, 95% CI 0.64-0.82, P<0.001). Every 1-year extension in RLD was linked to a 2% reduction in the risk of UACR elevation ( OR=0.98, 95% CI 0.97-0.99, P<0.001). Stratified analysis revealed a more significant association between RLD and UACR in women who were a normal weight ( P=0.003) or overweight ( P=0.001), in those without CVD history ( P=0.001), and in those with impaired estimated glomerular filtration rate ( P=0.004). The mediation casual analysis showed that 3.0% of proteinuria inducing CVD events was mediated by RLD ( P=0.048). Conclusion:A longer RLD (37-50 years) is associated with a lower UACR in Chinese postmenopausal women.

Correlation between hemoglobin level and diabetic retinopathy in patients with type 2 diabetes mellitus / 中华内分泌代谢杂志

Objective:To evaluate the relationship between hemoglobin(Hb) level and the risk of diabetic retinopathy(DR) in patients with type 2 diabetes mellitus(T2DM).Methods:This study was a prospective cohort study. A total of 1 730 T2DM patients without DR, who received regular management at the Li′s Clinic in Taiwan, China starting from 2002, were selected as the study population. All patients underwent annual dilated fundus examination by professional ophthalmologists. General patient information and laboratory results were collected and analyzed. Based on the occurrence of DR during patient follow-up, patients were divided into the DR group and the non-DR(NDR) group. The impact of Hb levels on DR was explored using a generalized linear mixed model, and the relationship between Hb levels and DR was studied using Cox proportional hazards regression model.Results:After an average follow-up of 9.79 years, 481 patients with DR were detected. Compared with NDR group, DR group displayed a longer course of diabetes, higher rates of cataract, insulin use, and anemia, and higher systolic blood pressure, HbA 1C, and UACR as well as lower Hb. The results of the generalized linear mixed model showed a negative correlation between Hb and the occurrence of DR( β=-0.015, P<0.001). The Cox proportional hazards regression model showed that, after adjusting for confounding variables and based on quartiles of average Hb levels during follow-up, the risk of developing DR increased by 56.9% in the Q1 group(Hb≤127 g/L) compared to the Q4 group(Hb≥142 g/L). The cumulative risk plot showed that, after adjusting for confounding variables, the Q1 group had the highest cumulative risk of developing DR, and the difference was statistically significant( P<0.05). Conclusion:Hb was negatively correlated with DR, and the lower Hb levels were associated with the occurrence of DR, independent of other influencing factors.

ObjectiveTo obtain the prevalence of sarcopenia in middle-aged and elderly people in Urumqi based on the 2020 updated based on the 2020 updated Consensus Report 2019 of Asian Working Group for Sarcopenia （AWGS2019）， and to further explore the association between sarcopenia and metabolic syndrome （MS）. MethodsA total of 1 438 middle-aged and elderly people （aged≥50 years） in Urumqi from July 2018 to January 2019 were selected as the research subjects. Data were collected by questionnaire survey， physical examination and laboratory test. Skeletal muscle mass，grip strength and 4 m walking speed were used to represent muscle mass， muscle strength and body function， respectively. Bioelectrical impedance analysis （BIA） was used to measure human body components. Based on the diagnostic criteria of sarcopenia recommended by AWGS2019， the prevalence of sarcopenia in people over 50 years old was obtained. Multivariate logistic regression model was used to explore the correlation between sarcopenia and MS in middle-aged and elderly people of different genders. ResultsThere were 194 patients with sarcopenia， with a prevalence of 13.49%. The prevalence was 15.56% in males and 12.12% in females. There was no significant difference in the prevalence of MS between male sarcopenia group （40.45%） and non-sarcopenia group （38.92%）， while the prevalence of MS in female sarcopenia group （39.04%） was higher than that in non-sarcopenia group （27.56%）. Multivariate logistic regression analysis showed that sarcopenia was a related factor of MS. Compared with non-sarcopenia， the risk of MS in male sarcopenia group was higher （OR=2.11，95%CI： 1.15‒3.88 ）. ConclusionSarcopenia increases the risk of MS in middle-aged and elderly people， with a greater risk in men. Fully understanding of sarcopenia is helpful to early identify high-risk groups of MS and prevent the occurrence of MS.

Role of p38 MAPK/CREB signaling pathway in tetramethylpyrazine-induced reduction of hippocampal inflammatory responses in mice with sepsis-associated encephalopathy / 中华麻醉学杂志

Objective:To evaluate the role of p38 mitogen-activated protein kinase (MAPK)/cyclic adenosine monophosphate response element-binding protein (CREB) signaling pathway in tetramethylpyrazine-induced reduction of hippocampal inflammatory responses in mice with sepsis-associated encephalopathy (SAE).Methods:Sixty healthy male C57BL6 mice, weighing 24-27 g, were divided into 4 groups ( n=15 each) using a random number table method: sham operation group (group Sham), sepsis group (group Sep), tetramethylpyrazine group (group TMP) and p38 MAPK inhibitor SB203580 group (group SB). The model of SAE was established by cecal ligation and puncture in anesthetized mice.Tetramethylpyrazine 10 mg/kg was injected intraperitoneally once a day at 3 days before the establishment of the model in TMP group, and SB203580 2.0 mg/kg was intraperitoneally injected at 30 min after the establishment of the model in SB group.The equal volume of normal saline was given intraperitoneally in Sham and Sep groups.At 1 day after operation, cognitive function was assessed by Morris water maze, and the escape latency and ratio of time spent in the target quadrant were recorded.The animals were sacrificed after the test, and hippocampal tissues were taken for determination of the contents of interleukin-1beta (IL-1β), tumor necrosis factor-alpha (TNF-α) and IL-6 (by enzyme-linked immunosorbent assay) and for detection of the expression of phosphorylation of p38 MAPK, GSK3 and CREB and expression of brain-derived neurotrophic factor (BDNF) (by Western blot). Results:Compared with group Sham, the escape latency was significantly prolonged, the ratios of time spent in the target quadrant were decreased, the contents of IL-1β, TNF-α and IL-6 were increased, the phosphorylation of hippocampus p38 MAPK was increased, the phosphorylation of GSK3 and CREB were decreased, and the expression of BDNF was down-regulated in Sep, TMP and SB groups ( P<0.05). Compared with group Sep, the escape latency was significantly shortened, the ratios of time spent in the target quadrant were increased, the contents of IL-1β, TNF-α and IL-6 were decreased, the phosphorylation of hippocampus p38 MAPK was decreased, the phosphorylation of GSK3 and CREB were increased, and the expression of BDNF was up-regulated in TMP and SB groups ( P<0.05). Compared with group TMP, no significant change was found in the parameters mentioned above in group SB ( P>0.05). Conclusion:p38 MAPK/CREB signaling pathway is involved in the process of tetramethylpyrazine-induced reduction of hippocampal inflammatory responses in mice with SAE.

Surgical methods and clinical efficacy of different types of cesarean scar pregnancy / 中国基层医药

Objective:To compare surgical methods and clinical efficacy among different types of cesarean scar pregnancy (CSP).Methods:A total of 158 patients with CSP who received treatment in Yuncheng Central Hospital from January 2016 to June 2019 were included in this study. According to Expert Consensus on Diagnosis and Treatment of Cesarean Scar Pregnancy (2016 version), type I CSP was found in 55 patients, type II in 86 patients and type III in 17 patients. These patients were divided into groups A (ultrasound-guided suction curettage), B (uterine artery chemoembolization + ultrasound-guided suction curettage) and C (laparoscopic scar pregnancy lesion resection + scar repair) according to different surgical methods. The amount of intraoperative blood loss, the difference in human chorionic gonadotropin (HCG) level between before and after surgery, the time to postoperative HCG level returning to normal level, menstruation recovery, and re-pregnancy were compared between groups.Results:The amount of intraoperative blood loss in the groups A, B and C was (43.33 ± 72.31) mL, (34.41 ± 17.16) mL, (65.71 ± 70.52) mL, respectively. There was significant difference between groups ( F = 8.51, P = 0.014]. The difference in HCG level between before and after surgery in groups A, B and C was (0.64 ± 0.18), (0.79 ± 0.10), (0.76 ± 0.19), respectively. There was significant difference in the difference in HCG level between groups ( F = 19.21, P < 0.001). There was significant difference in the incidence of postoperative menstrual volume reduction between group B and the other two groups ( χ2 = 6.73, P = 0.003). After surgery, intrauterine pregnancy occurred in 12 patients, including 8 patients in group A (type I CSP in 2 patients, type II CSP in 3 patients, type III CSP in 3 patients), 4 patients in group B (type I CSP in 3 patients, type II CSP in 1 patient). Finally, full-term fetus delivery by cesarean section was performed in 6 patients (4 patients in group A and 2 patients in group B). Conclusion:Uterine artery chemoembolization combined with uterine curettage had less blood loss, during surgery and leads to an obvious decrease in HCG level, but it can result in reduction of menstrual volume. Ultrasound-guided suction curettage is preferred for type I and type II CSP. Balloon compression can be used to stop bleeding if massive bleeding occurs. Laparoscopic scar pregnancy lesion resection plus scar repair is recommended for type III CSP.

Objective:To investigate the relationship between serum homocysteine (HCY), folate (FOL) and methylenetetrahydrofolate reductase (MTHFR) C677T, A1298C gene polymorphism in patients with type 2 diabetic nephropathy (DN).Methods:A total of 161 patients with type 2 diabetes diagnosed in Jiangsu Shengze Hospital between January 2017 and December 2018, including 81 DN (41 males, 40 females; age: (61.5±14.2) years), 80 diabetic mellitus without nephropathy (DM; 42 males, 38 females, age: (57.7±10.8) years), and 77 normal controls (NC; 39 males, 38 females, age: (58.2±16.3) years) were retrospectively analyzed. The serum levels of HCY and FOL were detected by enzyme circulation and electrochemiluminescence respectively. TaqMan genotyping technique was used to detect MTHFR 677T&A1298 gene polymorphism. The serum levels of HCY and FOL were compared with one-way analysis of variance (the least significant difference t test), and the distribution differences of MTHFR gene were analyzed by χ2 test. Results:The difference of HCY level among DN, DM and NC groups was significantly different ((19.76±7.81), (15.62±5.01) and (8.09±3.74) μmol/L; F=81.738, P<0.001). The FOL level among the 3 groups was also significantly different ((12.18±3.01), (13.50±2.71) and (15.43±2.95) μg/L; F=26.978, P<0.001). The frequencies of 677T allele (51.2%, 83/162), 677TT/1298AA genotype (25.9%, 21/81) in DN group were significantly higher than those in DM (33.1%, 53/160; 11.2%, 9/80) and NC (33.8%, 52/154; 10.4%, 8/77) groups ( χ2 values: 10.821, 9.099, both P<0.05), but the 1298C allele frequency was not significantly different among the 3 groups (21.6%(35/162, DN) vs 16.9%(27/160, DM) vs 18.2%(28/154, NC); χ2=1.269, P>0.05). The levels of HCY and FOL in individuals with 677TT/1298AA genotype were significantly higher than those in individuals with other genotypes ( F values: 12.955, 15.504, all P<0.05). Conclusion:The abnormal metabolism of HCY and FOL caused by MTHFR C677T&A1298C gene polymorphism may be the genetic risk factor of DN.

Research progress in pachychoroid spectrum disease / 国际眼科杂志(Guoji Yanke Zazhi)

@#Choroidal thickening spectrum diseases include pachychoroid pigment epitheliopathy(PPE)central serous chorioretinopathy(CSC), pachychoroid neovascularization(PNV)and polypoidal choroidal-vasculopathy(PCV). PPE refers to permanent abnormal increase in choroidal thickness. It is manifested as dilatation of large choroidal vessels(Haller layer)oppressing the surrounding middle vascular layer(Sattler layer)and capillary layer(Choriocapillaris layer), resulting in insufficient blood supply to the retinal pigment epithelium and causing a series of retinitis pigmentosa. The other three diseases can progress from the pachychoroid pigment epitheliopathy. The study of the pathogenic characteristics and imaging changes of choroidal thickening spectrum diseases will help to explore the diseases' pathogenesis, providing reference for early clinical diagnosis, prevention and treatment.

Radiography study on osteotome sinus floor elevation with placed implant simultaneously with no graft augmentation / 北京大学学报(医学版)

OBJECTIVE@#To investigate the change of endo-sinus bone height and bone volume in osteotome sinus floor elevation (OSFE) without bone graft but placing implants simultaneously by using cone beam computed tomography (CBCT) and three dimensional analysis, and to find the impacting factors on endo-sinus bone augmentation.@*METHODS@#OSFE was performed in 38 edentulous patients with missing teeth at posterior maxillary region, and 44 implants were placed and referred for OSFE using no graft materials. CBCT was performed pre-surgery and 9－68 months post-surgery when the patients encountered another implant surgery. The gained bone height at mesial, distal, buccal and palatal sites around the implant in sinus were measured, volumetric measurements of the endo-sinus gained bone volume (ESGBV) in the elevated region were calculated by Mimics software. Univariate analysis and multiple linear regression were performed to investigate the impacting factors on the gained bone height and ESGBV. Marginal bone loss was recorded according to the periapical radiography after implant restoration.@*RESULTS@#The mean residual bone height (RBH) pre-surgery was (3.41±1.23) mm, the mean protruded length (PL) into sinus of implant post-surgery was (3.41±1.28) mm, the mean endo-sinus gained bone height was (2.44±1.23) mm at distal sites, (2.88±1.20) mm at mesial sites, (2.83±1.22) mm at buccal sites and (2.96±1.16) mm at palatal sites, the mean endo-sinus gained bone height at distal sites was significantly lower than the other three sites (P < 0.05). The average endo-sinus gained bone height was (2.78±1.13) mm. The mean ESGBV was (122.15± 73.27) mm3. Univariate analysis showed the more RBH, the less bone height gained in sinus, which existed at buccal, lingual, mesial and distal sites (P < 0.001), and the more RBH, the smaller ESGBV gained (P=0.012). The ESGBV was significantly higher in the subjects whose bone generation period was more than 24 months than those whose bone generation period less than 24 months (P=0.034). The more PL, the more bone height and ESGBV gained (P=0.008). Multivariate analysis showed after adjusting factors of gender, age, smoking, width of sinus floor, thickness of sinus membrane pre-surgery, diameter and length of the implant, PL and bone generation period was positively correlated with mean endo-sinus gained bone height and ESGBV, while RBH negatively correlated with mean endo-sinus gained bone height. During the follow-up, the mean marginal bone loss was 0 (0－1.41) mm and all the implants loaded successfully.@*CONCLUSION@#OSFE without bone graft but with placed implant simultaneously can increase endo-sinus gained bone height and ESGBV. RBH, PL and bone generation period are the significant factors impacting endo-sinus bone augmentation.

And dry eye symptom score, Schirmer I test(SⅠt), tear film break-up time(BUT)and corneal fluorescein staining(CFS)results were obtained before treatment, at the 1 and 3mo after initiation of treatment. <p>RESULTS: No statistically differences were observed in any of the indexes between the control group(dry eye symptom score: 13.52±2.15, SⅠt: 5.22±2.23, BUT: 5.02±1.58, CFS:2.82±0.81)and the treatment group(dry eye symptom score: 13.75+3.05, SⅠt: 5.54+2.89, BUT: 5.14+1.84, CFS: 2.73±0.45)before initiating treatment. One month later, the dry eye symptom score of the control group(12.22±2.64)and the treatment group(11.42±2.06)improved after treatment; the SⅠt of the control group(7.94±2.15)and the treatment group(8.63±2.78)also improved after treatment, and result of the treatment group was better than that of the control group, and the difference was statistically significant; the BUT of the control group(5.32±1.34)and the treatment group(5.46±1.45)were better after treatment, but the difference was not statistically significant. After 3mo treatment, the dry eye symptom score, SⅠt, BUT and CFS of the control group were 11.57±2.98, 8.44±2.35, 5.92±1.75, 1.92±0.44, respectively, and the dry eye symptom score, SⅠt, BUT and CFS of the control group were 9.23±2.34, 10.45±2.65, 5.92±1.75, 8.69±1.78, 1.59±0.79, respectively(<i>P</i><0.05).<p>CONCLUSIONS: Combination therapy of sodium hyaluronate eye drop and cyclosporine A eye drops treatments are effective for the treatment of mixed dry eye syndrome.

Prognostic analysis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma / 肿瘤研究与临床

Objective:To compare the prognosis of fluoroucil combined with cisplatin and paclitaxel combined with cisplatin regimens with concurrent radiotherapy in treatment of esophageal squamous cell carcinoma.Methods:A total of 120 patients with esophageal squamous cell carcinoma who were admitted to Anyang Tumor Hospital of Henan Province from December 2012 to November 2018 were randomly divided into group A and group B by using a random number generator. Group A was given cisplatin combined with 5-fluorouracil, and group B was given cisplatin combined with paclitaxel. Both groups had the same radiotherapy regimen, and both used intensity-modulated radiation therapy (IMRT). Completions of 50 Gy radiotherapy and at least one cycle of chemotherapy were considered to be in line with the plan. Survival data was analyzed in the term of intention-to-treat (ITT) and per-protocol (PP) set.Results:Of the 120 patients, 114 patients were treated and the adverse reactions could be evaluated, including 55 cases in group A and 59 cases in group B. The incidence of grade Ⅲ-Ⅳ leukopenia in group B was higher than that in group A [49.2% (29/59) vs. 25.5% (14/55)], and the difference was statistically significant ( χ2 = 6.805, P = 0.012), and there were no statistical differences in the other adverse reactions between the two groups (All P > 0.05). A total of 113 cases can be analyzed for survival. According to ITT analysis, the median progression-free survival (PFS) time in group A and group B was 28.0 months (95% CI 15.5-34.5 months) and 27.0 months (95% CI 17.0-41.0 months), the median overall survival (OS) time was 28.0 months (95% CI 15.8-34.2 months) and not reached, the differences were not statistically significant (both P > 0.05). According to PP analysis, the median PFS time in group A and group B was 28.0 months (95% CI 15.8-34.2 months) and 29.0 months (95% CI 14.9-45.1 months), the median OS time in group A and group B was 28.0 months (95% CI 3.7-52.3 months) and not reached, the differences were not statistically significant (both P > 0.05). Conclusions:The fluorouracil combined with cisplatin regimen and paclitaxel combined with cisplatin regimen with concurrent radiotherapy have similar PFS and OS time in treatment of esophageal squamous cell carcinoma, the adverse reactions are different, but they are all tolerable. In individualized clinical practice, the toxicities and costs of the two regimens can be comprehensively considered.

Research on the evaluation system of Party building work in public hospitals based on target management theory / 中华医院管理杂志

Establishment of an appraisal system in line with the Party building work of the new era, is imperative for implementation of the Party building responsibility system and furthering Party building quality. In September 2019, the authors customized a questionnaire and surveyed 629 in-job Party members of 10 tertiary public hospitals. By means of literature review, questionnaire surveys and expert interviews, they studied the current Party building appraisal system and existing problems. In addition, they probed into the significance of applying target management theory in the appraisal of Party building work at public hospitals, and applied such a theory in setting up a Party building appraisal system in line with the requirements of the Party in the new era, in such aspects as appraisal goal setting, management of the appraisal process, improvement of the appraisal system, and feedback of appraisal results.

Efficacy and safety of tranexamic acid in total hip arthroplasty via direct anterior approach / 中国骨伤

OBJECTIVE@#To evaluate the efficacy and safety of local application of tranexamic acid (TXA) in reducing perioperative blood loss in total hip arthroplasty via direct anterior approach (DAA).@*METHODS@#From July 2013 to September 2018, 46 patients with avascular necrosis of the femoral head were divided into tranexamic acid group (@*RESULTS@#The incision healed well and no obvious complications occurred in the two groups. All patients were followed up for 12 to 59 months(averaged 31.11 months). No hip pain was found in the follow-up patients. Hip joint function was improved effectively and no prosthesis loosening occurred. The total perioperative blood loss in tranexamic acid group and normal saline group was(740.09±77.14) ml and (1 069.07±113.53) ml respectively, 24 hours after operation, the drainage volume was (87.61±9.28) ml, (233.83±25.62) ml, the hidden blood loss was (409.65±38.01) ml and (588.33±57.16) ml. the difference of hemoglobin before and after operation was (24.78±2.19) g / L and (33.57±2.95) g / L, the difference was statistically significant (@*CONCLUSION@#local application of tranexamic acid in total hip arthroplasty through direct anterior approach can safely and effectively reduce perioperative blood loss, and does not increase the risk of thrombosis, and does not affect the normal recovery of joint function.
