ObjectiveTo construct an outcome set for clinical evaluation of traditional Chinese medicine （TCM） for chronic pulmonary heart disease， and to provide consensus outcomes for the evaluation of the clinical effectiveness of TCM for chronic pulmonary heart disease. MethodsWe searched randomised controlled trials of TCM for chronic pulmonary heart disease on China National Knowledge Infrastructure （CNKI）， Wanfang Data Knowledge Service Platform （WF）， VIP Chinese Science Journals Database （VIP）， Chinese Biomedical Literature Service Database （SinoMed）， PubMed， Cochrane Library， and Embase. We also searched Chinese Clinical Trial Registry Platform and the U.S. Clinical Trial Registry database to obtain the outcome indicators reported in the clinical research protocols of TCM for chronic pulmonary heart disease. The outcome indicators were also collected through semi-structured interviews of clinicians and patients. Then integrated the outcome indicators collected by the above methods to construct the indicator pool. Through two rounds of Delphi surveys and a consensus conference， the core outcome set for clinical evaluation of TCM for chronic pulmonary heart disease was determined. ResultsAfter screening， there were 1313 literature meeting the criteria， and 595 outcome indicators were extracted， then combined with the outcomes from semi-structured interviews which clinicians and patients concerned， finally an indicator item pool containing 369 outcome indicators were formed. After the initial screening of indicators in the pool by the steering committee， 58 indicators were established into the initial list of indicator entries. In the first round of Delphi survey， the expert coordination coefficient for the results was 0.401， and the Cronbach coefficient was 0.989. A total of 35 indicators that did not meet the criteria ［＜70% of the participants rated the outcome as 7~9 （critical） and the mean of the expert ratings ＜7］ were deleted， and 23 were retained， with 7 new indicators added that were open to supplementation by the experts， resulting in a total of 30 indicators that were included in the second round of Delphi survey. In the second round of Delphi survey， the expert coordination coefficient was 0.303， and the Cronbach coefficient was 0.974， with a total of 7 indicators that did not meet the criteria being deleted， and 21 indicators being retained for the consensus conference. After the consensus meeting， the core outcome set for clinical evaluation of chronic pulmonary heart disease in two major categories， acute exacerbation stage and stable stage， was finally determined， in which there were four indicators in acute exacerbation stage： N-terminal B-type natriuretic peptide precursor （NT-proBNP）， blood qi analysis， all-cause mortality rate， and complication rate； and there were eight indicators in the stable stage： pulmonary function index， six-minute walk test distance， New York cardiac function classification， all-cause mortality rate， re-hospitalisation rate， Chronic Obstructive Pulmonary Disease Assessment Test （CAT） score， Short Form 36 Health Survey （SF-36）， and TCM syndrome score. ConclusionThe core outcome sets of TCM clinical evaluation in the acute exacerbation stage and stable stage are constructed， which is helpful to improve the practicability， comparability and transparency of TCM clinical research results in pulmonary heart disease.

OBJECTIVE: To investigate the effect of laparoscopic high ligation of spermatic cord vein in patients with chronic prostatitis and varicocele prostatitis. METHODS: A total of 90 varicocele patients were selected from January 2016 to December 2020, including 33 patients with chronic prostatitis. Changes of white blood cell count, National Institutes of Health chronic prostatitis symptom index (NIH-CPSI) score and serum testosterone level in the expressed prostate secretion (EPS) were observed before and after the operation of laparoscopic high ligation of spermatic vein. RESULTS: All patients were followed up three months after the surgery. There was no significant difference in the white blood cell counts in EPS, NIH-CPSI score, and serum testosterone level in patients with varicocele-only who underwent high ligation surgery after the operation. However, the white blood cell count in the EPS of patients with chronic prostatitis was lower than that before 3 months of operation ( ［12.39±4.23］×109/L vs ［21.36±5.05］×109/L). The NIH-CPSI score was significantly lower than that before operation ( ［12.71±6.21］ vs ［26.76±8.43］). And the serum testosterone level was higher than that before operation (［4.34±1.77］ng/ml vs ［2.36±1.05］ng/ml). CONCLUSION Laparoscopic high ligation of the spermatic vein in patients with chronic prostatitis and varicocele could effectively reduce the number of white blood cells in the EPS, boost the level of serum testosterone and improves symptoms of chronic prostatitis.

Growth arrest DNA damage-inducible protein 45 β (GADD45B) has been reported to be a regulatory factor for active DNA demethylation and is implicated in the modulation of synaptic plasticity and chronic stress-related psychopathological processes. However, its precise role and mechanism of action in stress susceptibility remain elusive. In this study, we found a significant reduction in GADD45B expression specifically in the ventral, but not the dorsal hippocampal CA1 (dCA1) of stress-susceptible mice. Furthermore, we demonstrated that GADD45B negatively regulates susceptibility to social stress and NMDA receptor-dependent long-term potentiation (LTP) in the ventral hippocampal CA1 (vCA1). Importantly, through pharmacological inhibition using the NMDA receptor antagonist MK801, we provided further evidence supporting the hypothesis that GADD45B potentially modulates susceptibility to social stress by influencing NMDA receptor-mediated LTP. Collectively, these results suggested that modulation of NMDA receptor-mediated synaptic plasticity is a pivotal mechanism underlying the regulation of susceptibility to social stress by GADD45B.

Objective:To explore the effect of group education intervention strategy based on harmonious nursing theory on understanding and application of pelvic floor knowledge and exercise skills in first gestation women, so as to promote the early recovery of pelvic floor function in postpartum women.Methods:This study was a quasi-experimental study. A total of 80 first gestation women in the pregnant women′s school of the First Hospital of Shanxi Medical University were selected as the research objects, 40 women from April to May 2023 were involved in the control group and 40 women from June to July 2023 were involved in the intervention group. The control group was given routine health education, while the intervention group was given group educational nursing intervention based on harmonious nursing theory. The Primary Prevention of Female Pelvic Floor Dysfunction-self-care Ability Scale was used to evaluate and compare the primary prevention self-care ability of pelvic floor dysfunction among pregnancy 1-4 weeks between the two groups before and after pregnancy intervention. Pelvic floor muscle strength was measured and pelvic floor function exercise compliance was evaluated during outpatient follow-up at 42-49 days postpartum (hereinafter referred to as postpartum 42 days) to evaluate and compare the rehabilitation effect of pelvic floor skills exercise between the two groups at 42 days postpartum.Results:Finally, the control group was (29.97 ± 3.68) years old involved 38 cases, and the intervention group was (29.79 ± 3.66) years old involved 38 cases. There was no significant difference in self-care ability score of primary prevention of pelvic floor dysfunction between the two groups before intervention ( P>0.05). After pregnancy intervention, the scores of self-care knowledge, self-care responsibility, self-care skills, self-regulation and total score of the intervention group were (58.13 ± 6.46), (11.73 ± 1.18), (10.16 ± 0.86), (29.21 ± 2.74) and (109.21 ± 8.92) points, respectively, which were higher than the control group (47.76 ± 4.25), (11.05 ± 1.09), (8.82 ± 1.78), (27.34 ± 2.18), (94.97 ± 6.46) points, and the differences between the two groups were statistically significant ( t values were - 8.26 - - 2.63, all P<0.05). In the intervention group, the maximum value of the fast muscle stage and the mean value of the slow muscle stage of the comparison of pelvic floor muscle strength between the two groups 42 days after delivery were 48.25(44.75, 53.45)μV and 31.00 (27.33, 34.23) μV, respectively, which were higher than the control group 36.80 (32.25, 44.28) μV and 22.40 (19.28, 25.88) μV, the differences between the two groups were statistically significant ( Z = - 4.98, - 5.37, both P<0.01). There was no significant difference in the average value of the pre-resting stage and the average value of the post-resting stage between the two groups ( P>0.05). Comparison of pelvic floor functional exercise compliance between the two groups showed that in the intervention group, the proportion of good compliance was 73.7% (28/38), and the proportion of general compliance was 26.3% (10/38), while in the control group, the proportion of general compliance was 86.8% (33/38) and the proportion of good compliance was 7.9% (3/38). The difference between the two groups was statistically significant ( χ2 = 34.46, P<0.01). Conclusions:Application of the theory of harmonious nursing group educational nursing intervention was carried out on the first gestation women, can effectively improve the first gestation women during pregnancy pelvic floor functional exercise primary prevention self-care ability level, strengthen puerperal women pelvic floor muscle, improve the puerperal pelvic floor functional exercise adherence, coordination and optimization of the first gestation women early for pelvic floor functional rehabilitation nursing process.

Objective To investigate the effect of fluid shear(FS)on apoptosis of glomerular epithelial cells(GECs)and the role of Piezo 1 protein in it.Methods GECs(glomerular epithelial cells)of SD rat were cul-tured.Fluid shear stimulation was simulated by a Flexcell-T5000 tensiometer.Apoptosis level was detected by flow cytometry.The expression of Piezo 1 proteins in GECs was detected by immunofluorescence staining.The activating of Piezo 1 channels by fluid shear was observed using Ca2+indicator(Cal-590 AM).The effect of Piezo 1 on apop-tosis in GECs was analyzed after modulating the function or expression of Piezo 1 protein using the chemical activa-tor Yoda1,the inhibitor GsMtx 4 was regulated by lentivirus Lv-shPiezo 1.Results Compared with the blank controlgroup,apoptosis increased in the fluid shear group(P＜0.05).The rate of apoptosis increased with the enhancing of fluid shear strength;Piezo 1 was commonly expressed in GECs.Fluid shear activated Piezo 1 chan-nel and enhanced expression of Piezo 1.The agonist Yoda1 promoted the apoptosis of GECs GsMtx 4 inhibited the apoptosis induced by fluid shear.Lv-shPiezo 1 knocked down the expression of Piezo 1 in GECs and the apoptosis rate of GECs in the knockdown group was reduced as compared to that in the control group and Lv-Ctrl group(P＜0.05).Conclusions Fluid shear may promote apoptosis of GECs by activation of Piezo 1 and by enhancing expression of Piezo 1.

Primary sclerosing cholangitis(PSC)is a cholestatic disease characterized by chronic progressive bile duct inflammation and has a low incidence rate and poor prognosis in China.There is still no drug therapy that can change the course of PSC,and liver transplantation is the only effective treatment for PSC,with a 5-year survival rate of 85%after transplantation.Drug therapy for PSC is facing great challenges based on the current status of PSC.At present,drugs for the treatment of PSC are in the stage of clinical trials and have shown certain application prospect,among which ursodeoxycholic acid is the most widely studied and commonly used drug.In addition,there are many emerging drugs in the pipeline.This article summarizes the latest advances in drug therapy for PSC.

BACKGROUND:Proximal humeral fracture in older adults is one of the three major osteoporotic fractures.Anatomic locking plate fixation is the first choice for most scholars to treat difficult-to-reduce and complex fracture types.However,the probability of reduction failure after the operation is high,which seriously affects patients'quality of life. OBJECTIVE:To investigate the correlation between deltoid tuberosity index and postoperative reduction failure of proximal humeral fractures in the elderly,analyze and filter preoperative independent risk factors for reduction failure of proximal humeral fractures in the elderly,and construct and verify the effectiveness of a clinical prediction model. METHODS:The clinical data of 153 elderly patients with proximal humeral fractures who met the diagnosis and inclusion criteria and received open reduction and locking plate surgery in Foshan Hospital of TCM from June 2012 to June 2021 were collected.The patients were divided into the reduction failure subgroup and the reduction maintenance subgroup.The independent risk factors were selected by multivariate Logistic regression analysis,and the nomogram was constructed by R language.After 1000 times of resampling by Bootstrap method,the Hosmer-Lemeshow goodness of fit correlation test,receiver operating characteristic curve,calibration curve,clinical decision,and influence curve were plotted to evaluate its goodness of fit,discrimination,calibration ability,and clinical application value.Fifty-five elderly patients with proximal humeral fractures from June 2013 to August 2021 were selected as the model's external validation group to evaluate the prediction model's stability and accuracy. RESULTS AND CONCLUSION:(1)Of the 153 patients in the training group,44 patients met reduction failure after internal plate fixation.The prevalence of postoperative reduction failure was 28.8%.Multivariate Logistic regression analysis identified that deltoid tuberosity index[OR=9.782,95%CI(3.798,25.194)],varus displacement[OR=4.209,95%CI(1.472,12.031)],and medial metaphyseal comminution[OR=4.278,95%CI(1.670,10.959)]were independent risk factors for postoperative reduction failure of proximal humeral fractures in older adults(P<0.05).(2)A nomogram based on independent risk factors was then constructed.The Hosmer-Lemeshow test results for the model of the training group showed that χ2=0.812(P=0.976)and area under curve=0.830[95%CI(0.762,0.898)].The calibration plot results showed that the model's predicted risk was in good agreement with the actual risk.The decision and clinical influence curves showed good clinical applicability.(3)In the validation group,the accuracy rate in practical applications was 86%,area under curve=0.902[95%CI(0.819,0.985)].(4)It is concluded that deltoid tuberosity index<1.44,medial metaphyseal comminution,and varus displacement were independent risk factors for reduction failure.(5)The internal and external validation of the risk prediction model demonstrated high discrimination,accuracy,and clinical applicability could be used to individually predict and screen the high-risk population of postoperative reduction failure of proximal humeral fractures in the elderly.The predicted number of patients at high risk is highly matched to the actual number of patients who occur when the model's threshold risk probability is above 65%,and clinicians should use targeted treatment.

BACKGROUND:Internal fixation and open reduction with locking plate is the main treatment for proximal humeral fractures with medial column instability.However,reduction failure is one of the main postoperative complications,and accurate risk factor assessment is beneficial for screening high-risk patients and clinical decision selection. OBJECTIVE:To construct four types of prediction models by different machine learning algorithms,compare the optimal model to analyze and sort the risk variables according to their weight scores on the impact of outcome,and explore their significance in guiding clinical diagnosis and treatment. METHODS:262 patients with proximal humeral fractures with medial column instability,aged(60.6±10.2)years,admitted to Foshan Hospital of Traditional Chinese Medicine between June 2012 and June 2022 were included.All patients underwent open reduction with locking plate surgery.According to the occurrence of reduction failure at 5-month follow-up,the patients were divided into a reduction failure group(n=64)and a reduction maintenance group(n=198).Clinical data of patients were collected,and model variables and their classification were determined.The data set was randomly divided into a training set and a test set according to a 7:3 ratio,and the optimal hyperparameters were obtained in the training set according to a 5-fold cross-over test.Four machine learning prediction models of logistic regression,random forest,support vector machine,and XGBoost were constructed,and the performance of different algorithms was observed in the test set using AUC,correctness,sensitivity,specificity,and F1 scores,so as to comprehensively evaluate the prediction performance of the models.The best-performing model was evaluated using SHAP to assess important risk variables and to evaluate its clinical guidance implications. RESULTS AND CONCLUSION:(1)There were significant differences between the two groups in deltoid tuberosity index,fracture type,fracture end with varus deformity before operation,fragment length of inferior metaphyseal of humerus,postoperative reduction,cortical support of medial column of proximal humerus,and insertion of calcar screw(P<0.05).(2)The best-combined performance of the four machine models was XGBoost.The AUC,accuracy,and F1 scores were 0.885,0.885,and 0.743,respectively;followed by random forest and support vector machine,with both models performing at approximately equal levels.Logistic regression had the worst combined performance.The SHAP interpretation tool was used in the optimal model and results showed that deltoid tuberosity index,medial humeral column cortical support,fracture type,fracture reduction quality,and the status of the calcar screw were important influencing fators for postoperative fracture reduction failure.(3)The accuracy of using machine learning to analyze clinical problems is superior to that of traditional logistic regression analysis methods.When dealing with high-dimensional data,the machine learning approach can solve multivariate interaction and covariance problems well.The SHAP interpretation tool can not only clarify the importance of individual variables but also obtain detailed information on the impact of dummy variables in each variable on the outcome.

Objective:To investigate the prevalence of cataracts, the surgical coverage, and postoperative visual acuity of adults in Ningxia.Methods:A cross-sectional study using multistage cluster random sampling was conducted.Ten survey sites in Ningxia were selected and the population aged 18 years and over was surveyed with questionnaire, height and weight measurements, visual acuity, intraocular pressure, fundus photography and slit-lamp examinations.Cataract prevalence and its influencing factors were analyzed.Cataract prevalence, surgical coverage and presenting visual acuity (PVA) and best corrected visual acuity (BCVA) after surgery were investigated in different age groups of the examined population.The study adhered to the Declaration of Helsinki and was approved by the Ethics Committee of the People's Hospital of Ningxia Hui Autonomous Region (No.[2023]-LL-010).Participants signed informed consent prior to the examination.Results:A total of 6 145 people should be examined, and 5 721 people were actually examined, with an examination rate of 93.10%.The study population consisted of 2 558 males, accounting for 44.71%, and 3 163 females, accounting for 55.28%, with ages ranging from 18 to 93 years old and an average age of (64.27±13.48) years.Among them, 1 180 patients diagnosed with cataract, with a cataract prevalence of 20.62%.The prevalence of cataract increased with age and decreased with education level, showing statistically significant differences ( χ2=1 091.32, 581.92; both at P<0.01).The prevalence of cataract was significantly higher among people with hypertension, diabetes mellitus, hyperlipidemia, and coronary heart disease than those without these diseases ( χ2=274.65, 118.15, 78.05, 182.71; all at P<0.01).Cataract surgery was performed in 245 cases in the cataract patient population, with a surgical coverage rate of 20.76%.Of the 245 cases, 229 cases were implanted with IOLs, with an implantation rate of 93.40%.The social burden rate of cataract blindness was 2.29%, and increased with age.Of the 339 eyes that underwent cataract surgery, 241 had a PVA≥0.3, accounting for 71.09%, and 272 had a BCVA≥0.3, accounting for 80.24%. Conclusions:In Ningxia, cataracts are still the main cause of vision impairment and blindness in the elderly, and the social burden rate of cataract blindness is high.Moreover, the coverage rate of cataract surgery is low, so both the coverage and quality of surgery need improvement.
