Objective To analyze the prognostic value of serum microRNA(miRNA)-21-5p and miRNA-5189-5p expression levels in elderly patients with prostate cancer after laparoscopic radical prostatectomy(LRP).Methods A total of 213 elderly prostate cancer patients treated with LRP from January 2014 to Sep-tember 2018 in the First Affiliated Hospital of Hainan Medical College were retrospectively selected as the study objects.According to the 5-year follow-up outcome,the patients were divided into good prognosis group(87 cases)and poor prognosis group(126 cases).The preoperative clinical baseline data and the expression levels of serum miRNA-21-5p and miRNA-5189-5p were collected.Logistic regression analysis was used to screen the factors affecting the prognosis of patients.The prognostic prediction model was constructed with independent risk factors,and the predictive value was analyzed by drawing receiver operating characteristic(ROC)curve.Results Multivariate Logistic regression analysis showed that serum prostate specific antigen(PSA)level,positive incisal margin,and expression levels of miRNA-21-5p and miRNA-5189-5p were inde-pendent risk factors for the prognosis of elderly prostate cancer patients receiving LRP(P＜0.05).The com-bined prediction model was established based on independent risk factors,and the area under the curve of each factor alone predicting prognosis of elderly prostate cancer patients receiving LRP was less than that of four combined prediction(P＜0.05).Conclusion The expression levels of serum miRNA-21-5p and miRNA-5189-5p are of high value in predicting the prognosis of elderly prostate cancer patients after LRP.

Recent studies have shown that stress can substantially facilitate breast cancer metastasis,which can be reduced by nonselective β1/β2-adrenergic receptor(β1/β2-AR)blocker.However,several side effects were identified.Thus,it is extremely warranted to explore more effective and better-tolerated β2-AR blocker.Currently,we demonstrated that baicalin(BA),a major bioactive component of Scutellaria bai-calensis Georgi,could significantly attenuate stress hormones especially epinephrine(Epi)-induced breast cancer cell migration and invasion in vitro.Mechanistically,we identified that β2-AR was a direct target of BA via the drug affinity responsive target stability(DARTS)combined with mass spectrum assay,and BA photoaffinity probe with pull-down assay,which was further confirmed by a couple of bio-physical and biochemical assays.Furthermore,we demonstrated that BA could directly bind to the Phe-193 and Phe-289 of β2-AR,subsequently inhibit cyclic adenosine monophosphate-protein kinase A-focal adhesion kinase(cAMP-PKA-FAK)pathway,and thus impede epithelial-mesenchymal transition(EMT),thereby hindering the metastatic progression of the chronic stress coupled with syngeneic and xenograft in vivo orthotopic and tail vein mouse model.These findings firstly identify BA as a potential β2-AR inhibitor in the treatment of stress-induced breast cancer metastasis.

Purpose: The prognosis of patients with hepatocellular carcinoma (HCC) and portal vein tumor thrombus (PVTT) is extremely poor, and systemic therapy is currently the mainstream treatment. This study aimed to assess the efficacy and safety of lenvatinib combined with anti–programmed cell death-1 antibodies and transcatheter arterial chemoembolization (triple therapy) in patients with HCC and PVTT. Materials and Methods: This retrospective multicenter study included patients with HCC and PVTT who received triple therapy, were aged between 18 and 75 years, classified as Child-Pugh class A or B, and had at least one measurable lesion. The overall survival (OS), progression-free survival (PFS), objective response rates, and disease control rates were analyzed to assess efficacy. Treatment-related adverse events were analyzed to assess safety profiles. Results: During a median follow-up of 11.23 months (range, 3.07 to 34.37 months), the median OS was greater than 24 months, and median PFS was 12.53 months. The 2-year OS rate was 54.9%. The objective response rate and disease control rate were 69.8% (74/106) and 84.0% (89/106), respectively; 20.8% (22/106) of the patients experienced grade 3/4 treatment-related adverse events and no treatment-related deaths occurred. The conversion rate to liver resection was 31.1% (33/106), with manageable postoperative complications. The median OS was not reached in the surgery group, but was 19.08 months in the non-surgery group. The median PFS in the surgery and non-surgery groups were 20.50 and 9.00 months, respectively. Conclusion Triple therapy showed promising survival benefits and high response rates in patients with HCC and PVTT, with manageable adverse effects.

{L-End}Objective To investigate the current status of long working hours of food-delivery workers from food-delivery platform, and analyze its impact on their health such as occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction. {L-End}Methods A total of 2 145 food-delivery workers from two food-delivery platforms in Guangzhou City were selected as the research subjects using convenience sampling method. The occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and life satisfaction were investigated using the Core Occupational Stress Scale, Patient Health Questionnaire-9 items, Self-sleep Management Questionnaire, Self-diagnosis Questionnaire of Fatigue Accumulation of Workers, and World Health Organization Five-item Well Being Index. {L-End}Results The median and the 25th and 75th percentiles of weekly working hours were 63 (49,77) hours. And 92.2% (1 978/2 145) of workers, who worked more than 40 hours per week, were long working hours workers. While 70.1% (1 504/2 145) workers, who worked 55 hours or more per week, were ultra-long working hours workers. The detection rate of occupational stress, depressive symptoms, insomnia symptoms, fatigue accumulation, and low life satisfaction was 30.1%, 27.5%, 34.7%, 40.8%, and 75.1%, respectively. The longer the weekly working hours of the research subjects, the higher the detection rate of occupational stress and fatigue accumulation (all P<0.01). The results of multivariate logistic regression analysis showed that ultra-long working hours (weekly working hours ≥55 hours) was the influencing factor of occupational stress and fatigue accumulation after excluding the influence of confounding factors among workers (all P<0.05). {L-End}Conclusion The food-delivery workers of food-delivery platforms generally work long hours. Ultra-long working hours is a risk factor for occupational stress and fatigue accumulation among these workers.

{L-End}Objective To explore the status of quality control assessment of pure tone audiometry (PTA) and to analyze its influencing factors in occupational medical examination (OME) institutions in Guangzhou City. {L-End}Methods A total of 41 OME institutions in Guangzhou City were selected as the research subjects from 2021 to 2022 using random sampling method, and its status of on-site quality and PTA quality for individuals exposed to noise were assessed. {L-End}Results A total of 205 rectification items were identified among the 41 OME institutions from 2021 to 2022. Among them, 19, 28, 30, and 28 OME institutions did not meet the requirements of organizational structure, quality management system, quality control of OME, and health examination information reporting, respectively. A total of 1 095 OME reports for individuals exposed to noise were assessed, with 820 reports having correct results and conclusions, resulting in an accuracy rate of 74.9%. The results of the multiple logistic regression analysis showed that OME institutions without meeting the requirements for the quality management system had a higher risk of failing the PTA quality control assessment and having inaccurate hearing test results compared with those meeting the requirements (all P<0.05). OME institutions with a filing period less than one year had a higher risk of having inaccurate hearing test results than those with a filing period of one year or more (P<0.05). OME institutions not meeting the requirements for quality control of OME had a higher risk of having abnormal OME conclusions than those meeting the requirements (P<0.05). OME institutions not meeting the requirements for health examination information reporting had a higher risk of having abnormal conclusions in suspected occupational disease than those meeting the requirements (P<0.05). OME institutions not meeting the requirements for the quality management system had a higher risk of having abnormal conclusions of occupational contraindications than those meeting the requirements (P<0.05). {L-End}Conclusion The quality of PTA in OME institutions in Guangzhou City needs to be improved. And a well-established quality management system for OME is beneficial for improving the quality of PTA.

Objective:To summarize and analyze the current application status of oral mucosal graft (OMG) technique in the repair of ureteral strictures in China, and clarify the feasibility, safety and effectiveness of this technique.Methods:The 175 patients who underwent repair of ureteral stricture using oral mucosal patches from June 2015 to February 2022 were etrospectively analyzed in 14 medical centers in China, including 49 cases in Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, 32 cases in Affiliated Seventh Medical Center of PLA General Hospital, 3 cases in The Second Hospital of Anhui Medical University, 6 cases in The First Affiliated Hospital of Zhengzhou University, 56 cases in Peking University First Hospital, 3 cases in Sir Run Run Shaw Hospital, Zhejiang University School of Medicine, 3 cases in Shanghai Sixth People' s Hospital, 4 cases in General Hospital of Estern Theater Command, 4 cases in Lanzhou University Second Hospital, 2 cases in Guizhou Province People 's Hospital, 2 cases in Peking University People' s Hospital, 5 cases in Jinzhou First People's Hospital, 5 cases in The First Affiliated Hospital of Wannan Medical College, 1 case in Shandong Provincial Hospital. In this study, 127 patients (72.6%) used lingual mucosal patches, 32(18.3%) labial mucosa, and 16(9.1%) buccal mucosa. The surgical approach for OMG ureteral reconstruction was mainly minimally invasive, with robot-assisted laparoscopy in 84 patients (48.0%), traditional laparoscopic surgery in 87 patients (49.7%), and open surgery in only 4 patients (2.3%). There were 133 males and 42 females with an average age of (35.0±17.2) years. The mean body mass index (BMI) and stenosis length were (23.1±4.1) kg/m 2 and (4.7±1.8) cm, respectively. The stricture was located in the left ureter in 116 patients, right ureter in 58 case and bilateral ureter in 1 case. The most common causes of ureteral stricture were endoscopic surgery in 88(50.3%)patients, congenital stricture in 55(31.4%)patients, failed ureteroplasty in 29(16.6%)patients, history of extracorporeal shock wave lithotripsy in 13(7.4%)patients, radiotherapy history in 3(1.7%)patients and other causes in 6(3.4%)patients. Strictures were mainly located in the upper ureter, accounting for 61.7% (108/175 cases), followed by 36.0% (63/175) at the ureteropelvic junction and 2.3%(4/175)in the middle ureter. According to the surgical methods, the patients were divided into robot-assisted laparoscopic surgery group ( n=84), traditional laparoscopic surgery group ( n=87)and open surgery group ( n=4). Subgroup analysis of patients in robot-assisted laparoscopic and traditional laparoscopic surgery groups was performed. There were no significant difference in preoperative data between the two groups except for age (32.0±18.3) years vs.(37.0±15.9)years, P=0.040], BMI[(22.5±4.3)kg/m 2 vs. (23.7±3.6)kg/m 2, P=0.028], and etiology of stenosis [endoscopic injury, 34(40.5%) vs. 53(60.9%), P=0.012]. Preoperative hydronephrosis and stricture length were assessed by CTU and ureterography. Ureterography 7-9 weeks after surgery showed patency of the reconstructed segment, or no recurrence of hydronephrosis was judged as success. Evaluate the operation method, operation time, success rate, length of OMG in repairing ureteral stricture between laparoscopic and robot-assisted groups. Results:The overall success rate of oral mucosal graft repair surgery reached 97.7%(171/175). The success rate of ureteral reconstruction in the two groups were 96.4%(81/84)and 98.9%(86/87), respectively ( P=0.351), and the difference was not statistically significant. There was no significant difference for operation time, intraoperative blood loss, and mean oral mucosal length between the robotic and laparoscopic groups[(244.7±85.8) min and (222.7±83.5)min ( P=0.116), (58.9±38.6) ml and (68.4±45.5) ml ( P=0.217), (5.0±2.0) cm and (4.6±1.5) cm ( P=0.350)], respectively.Postoperative complications were reported in 23 (13.1%) patients, such as fever, urinary leakage, lymphatic leakage, infection, but only 2 (1.4%) cases patients had complications of Clavien-Dindo score ≥ Ⅲ. The two patients developed urinary stricture after surgery with failed conservative treatment, and no urinary stricture occurred following endoscopic treatment.The short-term (three months after surgery)incidence of complications in the site where the oral mucosa was taken, such as difficulty in opening mouth, pain, and swelling, was 12.0% (21/175), and there was no significant difference for oral complications between patients harvesting different length of mucosal graft. Conclusions:Ureteroplasty with oral mucosal graft is a safe, feasible and reliable technique for ureteral reconstruction. At present, minimally invasive technology is the main surgical approach for ureteroplasty, and there is no significant difference in operation time and success rate between robotic surgery and laparoscopic surgery.

Objective:To investigate the difference in left ventricular dysfunction between type 2 diabetes mellitus (T2DM) patients with hyperlipidemia and those without hyperlipidemia, and analyze the application value of three-dimensional speckle tracking technology.Methods:The clinical data of 70 patients with T2DM admitted to Heji Hospital Affiliated to Changzhi Medical College from January 2020 to June 2021 were retrospectively analyzed. Among these patients, 35 patients had hyperlipidemia and 35 patients had no hyperlipidemia. At the same time, 40 healthy subjects who concurrently underwent health checkups in the same hospital were included as healthy controls. All subjects underwent routine cardiac ultrasound and 3D-STE examinations. General clinical information and left ventricular function-related parameters, including global longitudinal strain, global circumferential strain, global area strain, and global radial strain were compared between healthy controls and T2DM patients with hyperlipidemia and those without hyperlipidemia.Results:The proportion of left ventricular remodeling increased in T2DM patients without hyperlipidemia, and the proportion of left ventricular hypertrophy was the highest in T2DM patients with hyperlipidemia. Global longitudinal strain and global circumferential strain in T2DM patients without hyperlipidemia were (-16.97 ± 2.59)% and (-17.41 ± 2.50)%, respectively, which were significantly higher than (-18.86 ± 2.46)% and (-18.71 ± 2.92)% in healthy controls ( t = 0.95, 0.57, both P < 0.05). Global longitudinal strain, global circumferential strain, and global area strain in T2DM patients with hyperlipidemia were (-14.98 ± 3.15)%, (-15.80 ± 3.16)%, (-27.17 ± 4.54)%, respectively, which were significantly higher than (-18.86 ± 2.46)%, (-18.71 ± 2.92)%, (-30.62 ± 4.02)% in healthy controls ( t = 0.46, 1.37, 0.98, all P < 0.05) and (-16.97 ± 2.59)%, (-17.41 ± 2.50)%, (-30.06 ± 3.59)% in T2DM patients without hyperlipidemia ( t = 0.37, 1.02, 0.77, all P < 0.05). Global radial strain in T2DM patients with hyperlipidemia was significantly higher than [(51.49 ± 8.94)%, t = 1.35, P < 0.05] in healthy controls and [(47.71± 8.46)%, t = 0.98, P < 0.05] in T2DM patients without hyperlipidemia. In patients with T2DM, fasting blood glucose and hyperlipidemia were independently correlated with all strain-related parameters. Conclusion:Hyperlipidemia can aggravate left ventricular remodeling and dysfunction in patients with T2DM and 3D-STE is one of the examination methods for subclinical left ventricular remodeling and dysfunction in T2DM patients with or without hyperlipidemia.

Performance evaluation of administrative personnel is challenging for performance reform of public hospitals. Constructing a reasonable performance evaluation plan for such personnel is conducive to promoting the high-quality and efficient development of hospitals. Hospital H has been exploring the implementation of performance evaluation reform for administrative personnel since 2019. Firstly, it clarified the responsibilities of various administrative management positions throughout the hospital and adopted the Hay position evaluation method for job value evaluation. Secondly, based on this, a performance evaluation index system covering common indexes, personality indexes, and implicit ability indexes was constructed, and the calculation and distribution methods of performance bonuses were clarified. The development of common indexes was based on the hospital′s " 14th Five Year Plan" , while individual indexes were used as key performance evaluation points of each department formulated according to the hospital′s annual key work breakdowns and the " 14th Five Year Plan" . The implicit ability index was constructed based on the competency model to guide and promote the personal development of employees. Finally, the hospital established a feedback and monitoring mechanism to ensure the steady operation of the performance evaluation plan. Thanks to the performance reform of administrative personnel based on job value evaluation, Hospital H has eliminated the phenomenon of " egalitarianism" in the distribution of administrative personnel performance, played a guiding and motivating role in performance evaluation for employees, and achieved better implementation of the hospital′s strategic goals. This can provide reference for the performance reform of administrative personnel in other medical institutions.

Objective:To construct a primary health care institutions performance evaluation index system from the perspective of health value orientation under the background of countywide medical alliances construction.Methods:From May 2021 to February 2022, preliminary screening was made on core performance evaluation indexes via literature review; purposive sampling was used to select the dean/vice dean, persons in charge of medical service, and those in charge of public health service responsible for performance evaluation at the community health service center. Then semi-structured interviews were made on the existing performance evaluation and assessment plans as well as existing problems of primary medical and health institutions. Based on the " input-process-output" performance evaluation model, the thematic framework analysis method was used to analyze the interview data, and combined with literature research results, a preliminary performance evaluation index system for primary medical and health institutions was built under the guidance of health value. From March to May 2022, the Delphi expert consultation method was used to evaluate the importance and operability of indexes. The threshold method was used to screen indexes, and analytic hierarchy process was used to calculate the weights of evaluation indexes.Results:The health value oriented performance evaluation index system for primary healthcare institutions included 3 first-level indexes, 9 second-level indexes, and 50 third-level indexes. The first-level indexes were output (0.377 3), input (0.336 3), and process (0.286 4) in descending order of weight. The top three weighted second-level indexes were health manpower(0.177 8), health literacy and health outcomes (0.157 6), as well as responsiveness and satisfaction (0.142 6). The third-level indexes included 17 medical indexes, 16 prevention indexes, and 17 medical prevention integration indexes. The top three weighted indexes for inpatient services were resident satisfaction with medical treatment (0.052 4), medical staff satisfaction (0.050 1), and responsiveness of residents seeking medical treatment (0.040 1); The top three weighted third-level indexes excluding inpatient services were resident satisfaction with medical treatment (0.052 4), medical staff satisfaction (0.050 1), and surplus funds used for personnel incentives (0.045 5).Conclusions:The performance evaluation index system of primary health care institutions built under the health value orientation is scientific, conducive to promoting the health-orientated transformation and improving the efficiency of primary health care services.

Objective:To study the risk factors for diabetic retinopathy(DR)in patients with coronary artery disease(CAD).Methods:353 patients with diabetes mellitus hospitalized at Beijing Anzhen Hospital between 2013 and 2015 were enrolled, including 96 patients with coronary artery disease(27%)and 156 patients with DR(44%).Medical history and examination/laboratory results of all patients were collected for analysis.Coronary artery disease was diagnosed according to coronary angiography.DR was diagnosed via ophthalmological examinations.The clinical characteristics of patients with and without DR were compared and contrasted between the groups.Results:Compared with patients without DR, patients with DR had a longer duration of diabetes, [15 years(10, 20) vs.8 years(4, 13), P<0.001]and a higher urine albumin/creatine ratio(UACR)[12.1 mg/g(3.2, 71.9) vs.4.8 mg/g(2.2, 3.5), P<0.001].Logistic regression analysis suggested that duration of diabetes( OR=1.107, 95% CI: 1.063~1.153, P<0.001)and UACR( OR=0.003, 95% CI: 1.001~1.006, P=0.008)were independent risk factors for DR.ROC curves revealed that a duration of diabetes >9.5 years or UACR>7.1 mg/g was significantly associated with DR.Also, of all patients with CAD, those with DR had a longer duration of diabetes[15 years(10, 20) vs.10 years(6, 15), P=0.002]and a higher percentage with hypertension(88.1% vs.67.6%, P=0.014).Hypertension history( OR=4.049, 95% CI: 1.099~14.925, P=0.036)and duration of diabetes( OR=1.159, 95% CI: 1.044~1.287, P=0.005)were independent risk factors for DR in patients with CAD.History of hypertension or a duration of diabetes>11.5 years was significantly associated with DR. Conclusions:In patients with coronary heart disease, hypertension history or a long duration of diabetes is significantly associated with an increased risk of DR.
