Objective:Under the guidance of " Opinions on Strengthening Party Construction in Public Hospitals" enacted by the Central Committee of the Communist Party of China, the performance evaluation index system for Party-committee secretaries has been released to reflect the overall leadership responsibility of Party committees at public hospitals.Methods:By means of literature review, policy learning and the preliminary work performance of Shanghai Hospital Development Center(SHDC), the framework of the target system was constructed. Three rounds of Delphi method were conducted to score 138 indicators based on eight aspects: result, objectivity, statistics, sensitivity, accessibility, quantifiability, importance and score-oriented. The final indicators were selected and statistically weighted. SPSS 20.0 software was used for descriptive statistical analysis, and Cronbach α evaluation coefficient method and Pearson correlation coefficient were also used to analyze the reliability and validity of indicators. Results:Following three rounds of Delphi research, 18 experts finally constructed a performance evaluation index system for Party committee secretaries that is composed of 4 level-1, 13 level-2 and 25 level-3 indexes. The new index system was used to simulate the scores of 14 hospitals, which was positively correlated with the survey results of third-party patient satisfaction( r=0.897, P<0.01), and was better than the original index system. Conclusions:The index system constructed in this study proves better quantitative objectivity and stronger operability. It has a good reliability and validity among the hospitals that belongs to SSHDC, and could be used for the evaluation of performance of Party-committee secretaries at public hospitals.

Objective:To analyze the clinical effects of intraoperative transesophageal echocardio-graphy(TEE)in different surgical methods for nephrectomy combined with Mayo Ⅲ-Ⅳ inferior vena cave(IVC)tumor thrombectomy.Methods:In the study,28 patients who did surgery of nephrectomy and Mayo Ⅲ-Ⅳ IVC thrombectomys in Peking University Third Hospital from 2022 January to 2024 February were included.Of the 28 patients,16 patients did robotic surgery,2 patients did laparoscopic surgery,and 10 patients did open surgery.All patients'clinical data were collected.Results:Intra-operative TEE was used in 9 robotic surgeries,of which 7 cases showed image changes compared with preoperative image results.Intraoperative TEE indicated that tumor thrombus entered the right atrium in 2 cases,showed that tumor thrombus grade rose from Mayo Ⅲ to Mayo Ⅳ in 2 cases,and indicated that tumor thrombus adhered to IC wall in 3 cases.All of these surgical plans were timely adjusted.Intra-operative TEE was used in 6 cases of open surgery,and 4 cases of them showed Mayo grade changes com-pared with preoperative image results.Intraoperative TEE indicated that tumor thrombus adhered to the IVC wall in 3 cases,and tumor thrombus adhered to the IVC wall with thrombus in one case.The surgi-cal plans were adjusted,and the tumor thrombus was left or segmentally removed.Laparoscopic surgery did not use intraoperative TEE.The effects of intraoperative TEE included:the combination of explora-tion and TEE monitoring was used in open surgery,and tumor thrombus removal process was fully moni-tored by intraoperative TEE in the robotic surgery.Intraoperative TEE real-time monitored circulatory sta-tus and cardiac function changes.Conclusion:In different surgical methods for nephrectomy com-bined with Mayo Ⅲ-Ⅳ tumor thrombectomy,intraoperative TEE can re-determine the tumor thrombus grade and degree of tumor thrombus adhered to IVC,track the tumor thrombus removal process in real-time,and monitor circulatory status and cardiac function changes.Intraoperative TEE plays an important role in different surgical methods,but its clinical application is still insufficient.Intraoperative TEE is recommended to such type of surgeries.

Objective: To explore the relationship between weight change and the changes in blood pressure, blood glucose and blood lipid profiles in middle-aged and elderly Chinese people. Methods: All participants were from the Dongfeng-Tongji cohort study. The study included 16 606 middle-aged and elderly Chinese people with complete information in the baseline survey in 2008 and the first follow-up survey in 2013. We collected the data on demographic characteristics, lifestyle, history of diseases and medication, and the results of medical health examinations, including height, weight, blood pressure, fasting blood glucose and lipid profiles. We divided the weight change into five groups, moderate or above weight loss (<-8.0%), slight weight loss (-8.0%, -3.1%), weight maintenance (-3.0%, 3.0%), slight weight increased (3.1%, 8.0%), and moderate or above weight increased (>8.0%). Generalized linear regression model was used to analyze the relationship between weight change and the changes in systolic blood pressure (SBP), diastolic blood pressure (DBP), fasting blood glucose (FBG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and triglyceride (TG). Subgroup analyses were used to explore the influences of gender, age and baseline BMI level on the relationship between weight change and the above-mentioned metabolic indicators. Results: The average age of participants in baseline survey was (62.19±7.28) years with a range of 45 to 89 years. During the five-year period, there were 18.86% (2 633), 28.03% (4 655), 35.87% (5 956), 13.96% (2 319), 6.28% (1 043) people with moderate or above weight loss, slight weight loss, weight maintenance, slight weight increased, and moderate or above weight increased, respectively. Regression analyses showed that body weight change were positively correlated with changes in SBP, DBP, FBG, TC, LDL-C and TG, and negatively correlated with change in HDL-C (all linear trend P values were<0.05); As every 10% of weight changed, the β (95%CI) of changes in SBP (mmHg) (1 mmHg=0.133 kPa), DBP (mmHg), FBG (mmol/L), TC (mmol/L), LDL-C (mmol/L), HDL-C (mmol/L) and TG (mmol/L) were 4.94 (4.32, 5.55), 2.50 (2.11, 2.88), 0.05 (0.02, 0.08), 0.13 (0.11, 0.16), 0.14 (0.12, 0.16), -0.05 (-0.07, -0.04) and 0.16 (0.14, 0.18), respectively. Furthermore, subgroup analyses showed that weight change can lead to greater changes in blood pressure in older and overweight or obesity elderly people (all P for interaction<0.05). Conclusion Weight loss was beneficial for middle-aged and elderly people to improve the blood pressure, blood glucose and blood lipid profiles, regardless of the weight at the baseline, while weight gain was not.

Objective To analyze the mammographic, MRI, and clinicopathological characteristics of primary breast lymphoma ( PBL ) . Methods Clinicopathological characteristics were retrospectively reviewed and analyzed in 32 patients with histopathologically proven PBL. All cases were female ( mean age, 50 years;median age 46 years;range, 30?68 years) . Results In the 32 cases, there were bilateral tumors in 5 cases and 27 cases of unilateral involvement. The patients presented with a painless mass in 25 cases and with pain in 7 cases. Rapid enlargement was observed in 6 cases. Mammograms of 17 tumors showed a round, circumscribed mass with high density or iso?density in 9, asymmetry in 7 and no abnormality was found in one. 37 lesions were detected on dynamic contrast?enhanced magnetic resonance imaging ( DCE?MRI) in 29 patients, among which 25 ( 67. 6%) lesions appeared as enhancing masses and 12 ( 32. 4%) lesions as non?mass enhancements. All lesions showed iso? or hypo?intense signal on the T1WI and hyper?intense signal on the T2W1. Analysis of the enhancing masses based on the 2013 ACR BI?RADS lexicon revealed that among the mass descriptors in 25 lesions, the most common features were circumscribed or irregular margin in 24 ( 96. 0%) and homogeneous internal pattern in 19 ( 76. 0%) . Of the 12 non?mass enhancing lesions, the most common descriptors included regional or multiple regional distribution in 6 (50.0%), and heterogeneous internal pattern in 8 (66.7%). The tumors showed early enhancement with penetrating vessels on DCE?MRI in 16 lesions, associated with skin thickening in 14, and axillary lymphadenopathy in 19. The time?signal intensity curve ( TIC) in 14 patients was mainly of typeⅢ( 7/14, 50.0%) . Conclusions Some imaging features may alert the diagnosis of primary breast lymphoma, but final diagnosis depends on histopathology. Early diagnosis is helpful for selecting appropriate treatment regimens.

Objective:To assess the efficacy and safety of 100 units of botulinum toxin A (BTX-A) intradetrusor injection in patients with overactive bladder.Methods:From April 2016 to December 2018, 17 tertiary hospitals were selected to participate in this prospective, multicenter, randomized, double-blind, placebo-controlled study. Two phases of study were conducted: the primary phase and the extended phase. This study enrolled patients aged 18 to 75 years who had been inadequately managed by anticholinergic therapy (insufficient efficacy or intolerable side effects) and had spontaneous voiding with overactive bladder. Exclusion criteria included patients with severe cardiac, renal and hepatic disorders, patients with previous botulinum toxin treatment for 6 months or allergic to BTX-A, patients with urinary tract infections, patients with urinary stones, urinary tract tumors, diabetes mellitus, and bleeding tendency. Eligible patients were randomly assigned to BTX-A group and placebo control group in a ratio of 2∶1. Two groups of patients received 20 intradetrusor injections of BTX-A 100U or placebo at the depth of the submucosal muscle layer respectively under cystoscope, including 5 injections at the base of the bladder, 3 injections to the bladder triangle, 5 injections each to the left and right walls and 2 injections to the top, sparing the bladder neck. As a placebo control group, patients received same volume of placebo containing no BTX-A and only adjuvant freeze-dried preparations for injection with the same method. A combination of gelatin, sucrose, and dextran served as adjuvants. Average micturition times per 24 hours, urinary incontinence (UI) episodes per day, average micturition volume per day, OAB symptom score(OABSS), and quality of life (QOL) score were recorded at baseline and the 2nd, 6th and 12th week after treatment. The primary efficacy endpoint was the change from baseline in the average micturition times per 24 hours at the 6th week after treatment. The secondary efficacy endpoints included the change from baseline in the average micturition times per 24 hours at 2nd and 12th week, as well as the change from baseline in the OABSS, QOL score, average frequency of urgency and UI episodes per day, urgency score, average micturition volume per day at 2nd, 6th and 12th week after treatment. Patients were followed for 12 weeks to assess adverse events (AEs). After assessed at week 12, if the micturition times has decreased less than 50% compared to baseline and the patient is willing to receive retreatment, then patients could enter the extended trial phase. In that phase, patients in both groups were injected with 100 units BTX-A from 12th week onwards and then followed up the same indicators for 12 weeks.Results:216 patients were enrolled in this trial (144 cases in the BTX-A group and 72 cases in the placebo control group). Baseline characteristics such as age (47.75±14.20 in the BTX-A group and 46.39±15.55 in the control group), sex (25 male/117 female in the BTX-A group and 10/61 in the control group), and disease duration (0.51 years in the BTX-A group and 0.60 years in the control group) were balanced between the two groups( P>0.05). A marked reduction from baseline in average micturition times per 24 hours was observed in all treatment groups at the 6th week and the reduction of the two groups was statistically different ( P<0.001 and P=0.008 respectively). Compared with the baseline, the average micturition times per 24 hours at the 6th week decreased from baseline by 2.40(0.70, 4.60)times for the BTX-A group and 0.70(-1.00, 3.30) times for the placebo control group respectively, and the difference between the two groups was considered to be statistically significant ( P=0.003). The change rates of average micturition times per 24 hours from baseline at the 6th week of the two groups were (16±22)% and (8±25)% respectively, and the difference between the two groups was statistically significant ( P=0.014). Compared with the baseline, the average micturition times per 24 hours at 2nd and 12th week decreased by 2.00(0.00, 4.00)and 3.30(0.60, 5.03)for the BTX-A group, 1.00(-1.00, 3.00)and 1.70(-1.45, 3.85)for the placebo control group respectively. The difference between two groups was considered to be statistically significant ( P=0.038 and P=0.012); the changes of average urgency times per day for the BTX-A group and the control group at the 2nd, 6th and 12th week were 2.00(0.00, 4.30)and 2.40(0.30, 5.00), 3.00(0.30, 5.70)and 0.70(-1.30, 2.70), 0.70(-1.30, 3.00) and 1.35(-1.15, 3.50), respectively. There were significant differences between two groups at the 2nd, 6th and 12th week, ( P=0.010, P=0.003 and P=0.025, respectively). The OABSS of the BTX-A group and the control group at the 6th week decreased by 1.00(0.00, 4.00)and 0.50(-1.00, 2.00) compared with the baseline, and the difference between the two groups was statistically significant ( P=0.003). 47 cases of BTX-A group and 34 cases of placebo control group entered the extended trial phase, and 40 and 28 cases completed the extended trial phase, respectively. The average micturition volume per 24 hours changed by -16.60(-41.60, -0.60)ml and -6.40(-22.40, 13.30)ml, (-35.67±54.41)ml and(-1.76±48.69)ml, (-36.14±41.51)ml and (-9.28±44.59)ml, (-35.85±43.35)ml and(-10.41±40.29)ml for two groups at the 12th, 14th, 18th and 24th week, and the difference between two groups was statistically significant at each follow-up time ( P=0.01, 0.006, 0.012 and 0.016, respectively). There was no significant difference in other parameters( P>0.05). However, adverse reactions after intradetrusor injection included increased residual urine volume (27 in the BTX-A group and 3 in the control group), dysuria (21 in the BTX-A group and 6 in the control group), urinary infection (19 in the BTX-A group and 6 in the control group), bladder neck obstruction (3 in the BTX-A group and 0 in the control group), hematuria (3 in the BTX-A group and 1 in the control group), elevated alanine aminotransferase (3 in the BTX-A group and 0 in the control group), etc. During the follow-up period, there was no significant difference in the other adverse events between two groups except the increase of residual urine volume( P<0.05). In the primary trial phase, among the 27 cases with increased residual urine volume in BTA group, only 1 case (3.70%) with PVR more than 300 ml; the PVR of 3 patients in the placebo group was less than 100 ml. The increase of residual urine volume caused by the injection could be improved or disappeared with the passage of time. Conclusions:Intradetrusor injection of Chinese BTX-A improved the average micturition times per 24 hours, the average daily urgent micturition times, OABSS, and average micturition volume per time, and reduced the adverse effects in patients with overactive bladder.Chinese BTX-A at dose of 100U demonstrated durable efficacy and safety in the management of overactive bladder.
