OBJECTIVE:The main clinical manifestations of knee osteoarthritis are pain,swelling,stiffness,and limited activity,which have a serious impact on the life of patients.Exercise therapy can effectively improve the related symptoms of patients with knee osteoarthritis.This paper uses the method of network meta-analysis to compare the efficacy of different exercise types in the treatment of knee osteoarthritis. METHODS:CNKI,WanFang,PubMed,Embase,Cochrane Library,Web of Science,Scopus,Ebsco,SinoMed,and UpToDate were searched with Chinese search terms"knee osteoarthritis,exercise therapy"and English search terms"knee osteoarthritis,exercise".Randomized controlled trials on the application of different exercise types in patients with knee osteoarthritis from October 2013 to October 2023 were collected.The outcome measures included visual analog scale,Western Ontario and McMaster Universities Osteoarthritis Index score,Timed Up and Go test,and 36-item short form health survey.Literature quality analysis was performed using the Cochrane Manual recommended tool for risk assessment of bias in randomized controlled trials.Two researchers independently completed the data collection,collation,extraction and analysis.RevMan 5.4 and Stata 18.0 software were used to analyze and plot the obtained data. RESULTS:A total of 29 articles with acceptable quality were included,involving 1 633 patients with knee osteoarthritis.The studies involved four types of exercise:aerobic training,strength training,flexibility/skill training,and mindfulness relaxation training.(1)The results of network meta-analysis showed that compared with routine care/health education,aerobic training could significantly improve pain symptoms(SMD=-3.26,95%CI:-6.33 to-0.19,P<0.05);strength training(SMD=-0.79,95%CI:-1.34 to-0.23,P<0.05)and mindfulness relaxation training(SMD=-0.79,95%CI:-1.23 to-0.34,P<0.05)could significantly improve the function of patients.Aerobic training(SMD=-1.37,95%CI:-2.24 to-0.51,P<0.05)and mindfulness relaxation training(SMD=-0.41,95%CI:-0.80 to-0.02,P<0.05)could significantly improve the functional mobility of patients.Mindfulness relaxation training(SMD=0.70,95%CI:0.21-1.18,P<0.05)and strength training(SMD=0.42,95%CI:0.03-0.81,P<0.05)could significantly improve the quality of life of patients.(2)The cumulative probability ranking results were as follows:pain:aerobic training(86.6%)>flexibility/skill training(60.1%)>strength training(56.8%)>mindfulness relaxation training(34.7%)>routine care/health education(11.7%);Knee function:strength training(73.7%)>mindfulness relaxation training(73.1%)>flexibility/skill training(56.1%)>aerobic training(39.9%)>usual care/health education(7.6%);Functional mobility:aerobic training(94.7%)>mindfulness relaxation training(65.5%)>strength training(45.1%)>flexibility/skill training(41.6%)>routine care/health education(3.2%);Quality of life:mindfulness relaxation training(91.3%)>strength training(68.0%)>flexibility/skill training(44.3%)>aerobic training(34.0%)>usual care/health education(12.3%). CONCLUSION:(1)Exercise therapy is effective in the treatment of knee osteoarthritis,among which aerobic training has the best effect on relieving pain and improving functional mobility.Strength training and mindfulness relaxation training has the best effect on improving patients'function.Mindfulness relaxation training has the best effect on improving the quality of life of patients.(2)Limited by the quality and quantity of the included literature,more high-quality studies are needed to verify it.

The present study employed UPLC-MS/MS to analyze and identify compounds in the raw powder of Tongluo Shenggu capsules. An HPLC method for the determination of vitexin content was established. The analysis of this drug was performed on a 30 ℃ thermostatic Acquity UPLC® BEH C18 (2.1 mm×100 mm,1.7 μm) column, with the mobile phase comprising 0.2% formic acid-methanol flowing at 0.3 mL /min in a gradient elution manner. Mass spectrometry was detected by ESI sources in both positive and negative ion modes for qualitative identification of chemical constituents. 12 flavonoid and 3 stilbenes compounds in the raw powder of Tongluo Shenggu capsules were successfully identified. Additionally, an HPLC method for the determination of vitexin content was established using a XBridge C18 column (4.6 mm × 250 mm, 5 µm) with a mobile phase of 0.05% glacial acetic acid in methanol for gradient elution, at a column temperature of 30 °C, a flow rate of 1.0 mL/min, and an injection volume of 20 μL. The method demonstrated good linearity in the concentration range of 10 µg/mL to 40 µg/mL (R=1.000) with an average recovery rate of 96.7%. The establishment of these methods provides a scientific basis for the quality control and development of the raw powder of Tongluo Shenggu capsules.

OBJECTIVE To evaluate the efficacy， safety and economy of inclisiran in the treatment of atherosclerotic cardiovascular disease with hypercholesterolemia. METHODS A rapid health technology assessment （HTA） approach was employed. HTA reports， systematic reviews（SR）/meta-analyses， and pharmacoeconomic studies related to inclisiran were systematically identified through comprehensive searches of Chinese and English databases， including PubMed， Embase， the Cochrane Library， CNKI and Wanfang database， supplemented by HTA institutional repositories. The search timeframe spanned from database inception to April 2025. The results of the studies were descriptively analysed and summarized through literature screening， data extraction and literature quality assessment. RESULTS The final analysis included 22 studies， comprising one HTA report， 15 SR/meta-analyses， and 6 pharmacoeconomic evaluations. Regarding therapeutic efficacy， compared with control group， inclisiran could significantly reduce the levels of low-density lipoprotein cholesterol， proprotein convertase subtilisin/kexin type 9， total cholesterol， triacylglycerol， apolipoprotein B， and lipoprotein（a）， increase the level of high-density lipoprotein cholesterol， and reduce the risk of adverse cardiovascular events. In terms of safety， the inclisiran group showed no significant difference compared with the control group in the risk of total adverse events， serious adverse events， or non-serious adverse events； however， an increased incidence of injection site reactions was observed， most of which were mild. In terms of cost-effectiveness， there were discrepancies in research conclusions both domestically and internationally. More studies indicated that inclisiran did not demonstrate cost-effectiveness advantage and would require an appropriate price reduction to meet cost-effectiveness criteria. CONCLUSIONS Inclisiran demonstrates favorable efficacy and acceptable safety in treating atherosclerotic cardiovascular disease with hypercholesterolemia， though its economic profile requires improvement.

Aim To preliminarily evaluate the effects of hypobaric hypoxia on organism damage in rats with post-traumatic stress disorder(PTSD),with a view to laying a foundation for drug research in plateau PTSD.Methods The rats were randomly divided into four groups,namely,the control(Control)group,the sin-gle-prolonged stress(SPS)group,the hypobaric hy-poxia(HH)group and the single-prolonged stress combined with hypobaric hypoxia(SPS+HH)group.The PTSD model was firstly constructed using the SPS method for rats in the SPS and SPS+HH groups.On the second day,rats in the HH group and SPS+HH group were placed in a low-pressure hypoxia chamber at a simulated altitude of 6000 m for 14 days.General condition,behavior,blood tests,and histomorphology were examined in order to evaluate the damage caused by low pressure hypoxia in PTSD rats.Results The body mass of rats in the SPS+HH group was signifi-cantly reduced;the feces were partly hard and lumpy,and some of them were seen to have high viscosity.Anxiety-like and depression-like behaviors were ob-served in all groups except in the control group,in which hypobaric hypoxia aggravated the behavioral ab-normalities in SPS rats.Rats in both the SPS and SPS+HH groups had coagulation dysfunction and abnor-mally increased blood viscosity,which was significantly abnormal in the SPS+HH group;erythrocytes,hemo-globin,and erythrocyte specific volume in whole blood of rats in the SPS+HH group were significantly in-creased compared with those of rats in the SPS group;and serum TP,LDH and GLU levels were abnormal in rats in the SPS+HH group.Dilated and congested blood vessels were seen in hippocampal tissue,conges-ted central veins were seen in hepatic tissue,and dilat-ed and congested liver sinusoids with mild granuloma-tous degeneration of hepatocytes were seen in rats of the SPS+HH group.Conclusion Hypobaric hypoxia exacerbates depression-like and anxiety-like behaviors in PTSD rats,as well as hematological indices and his-tomorphometric abnormalities in PTSD rats.

Objective To analyze the risk factors of gastrointestinal bleeding in patients with type A aortic dissection(TAAD)after Sun's operation.Methods The clinical data of 87 patients who underwent TAAD Sun's operation in our hospital from March 2021 to June 2022 were retrospectively analyzed.They were divided into the bleeding group and the non-bleeding group according to whether there was gastrointestinal bleeding after operation.The clinical data of patients in the two groups was compared and analyzed.The binary Logistic regression analysis was used to analyze the risk factors of gastrointestinal bleeding.The clinical predictor of postoperative gastrointestinal bleeding was analyzed by receiver operating characteristic(ROC)curve.Results In this study,there were 40 cases of postoperative gastrointestinal bleeding(the bleeding group)and 47 cases of non-bleeding(the non-bleeding group).Compared with the non-bleeding group,the bleeding group had a shorter onset time,a higher proportion of patients with hypertension history,a higher preoperative creatinine abnormality rate,more intraoperative blood loss,longer postoperative mechanical ventilation time,higher postoperative infection rate,and higher poor prognosis rate,with statistically significant differences(P<0.05).There was no statistically significant difference in the gender,age,gastrointestinal diseases history,smoking history,preoperative platelets,preoperative international normalized ratio(INR),preoperative alanine aminotransferase(ALT),preoperative aspartate aminotransferase(AST),preoperative γ-glutamyl transpeptidase(GGT),preoperative dissection involving abdominal aorta,operation time,intraoperative cardiopulmonary bypass time,intraoperative circulatory arrest time,intraoperative aortic occlusion time or intraoperative blood transfusion rate.Logistic regression analysis showed that hypertension history(OR=2.468,95%CI:0.862 to 7.067,P=0.037),preoperative creatinine>105 μmol/L(OR=3.970,95%CI:1.352 to 11.659,P=0.011),long postoperative mechanical ventilation time(OR=1.015,95%CI:0.094 to 1.018,P=0.041)and postoperative infection(OR=3.435,95%CI:0.991 to 11.900,P=0.012)were the independent risk factors for postoperative gastrointestinal bleeding in TAAD patients.ROC curve showed that the postoperative mechanical ventilation time exceeding 64 hours were the clinical predictor of postoperative gastrointestinal bleeding in TAAD patients.Conclusion The prognosis of TAAD patients with postoperative gastrointestinal bleeding after Sun's operation is poor.Hypertension history,preoperative acute renal insufficiency,long postoperative mechanical ventilation time and postoperative infection are closely related to postoperative gastrointestinal bleeding in TAAD patients after operation,which should be paid more attention to,and corresponding evaluation,early identification and early intervention should be made to improve the prognosis of patients.

The health insurance fund acts as the resource for the survival of medical institutions.However,it has shown a development trend of structural friction in the county.By analyzing the relationship between strategic purchasing and the function of health insurance system,this study clarifies the central position of payment and the roles of fund allocation and service compensation.By analyzing the reasons of the imbalance between the health insurance fund and primary services in the county,this study proposes that the strategic purchasing of health care services in the county needs to take into account both the front-end of payment-allocation,and the front-end of service--primary.On this basis,this study put forwards the strategic purchasing of primary health services,which aims to cut off the fund"competition"channel between hospitals and primary health care institutions by changing the fund distribution method;to guide the primary health care to proactively identify and satisfy the changes of the county's residents'service needs by adjusting the service compensation method;and supplemented with joint advocacy and collaborative supervision.The strategic purchasing of primary health services will gradually promote the development of primary health services in the county from sustainable to high-quality.

Objective:To evaluate the efficacy of adjusted Narcotrend Index (NI) value guidancecombined with small-dose esketamine for program-controlled closed-loop target-controlled infusion (TCI) system.Methods:Forty-eight American Society of Anesthesiologists Physical Status classificationⅠ or Ⅱpatients, regardless of gender, aged 18-55 yr, with body mass index of 18-25 kg/m 2, scheduled for elective laparoscopic surgery under general anesthesia, were assigned to control group (group C, NI baseline value median 36) and esketamine group(group E, NI baseline value median 46) using a random number table method, with 24 cases in each group. Anesthesia induction and maintenance were carried out using effect-site concentration TCI(Schnider model for propofol infusion and Minto model for remifentanil infusion). After the NI value was maintained at 26-46 during anesthesia maintenance, a small dose of esketamine was given (as an intravenous bolus 0.2 mg/kg, followed by an infusion of 5 μg·kg -1·min -1for 30 min) in group E, and the equal volume of normal saline was given instead in group C. Program-controlled closed-loop TCI was then started, and the target effect-site concentrations of propofol and remifentanil were adjusted every 5 min according to the corresponding preset NI baseline value. The main outcome measures were the percentage of time of NI value maintained in the target range within 1 h after administration of esketamine. Secondary outcome measures were the consumption of propofol and remifentanil, postoperative recovery time, incidence of nausea and vomiting, pain and shivering within 1 h after surgery. Patients were followed for intraoperative awareness on 2nd day after operation. Results:The performance of the program-controlled closed-loop TCI systems was within the safe clinical threshold, with no intraoperative awareness occurred in both groups. The consumption of propofol and remifentanil was significantly reduced in group E as compared to group C( P<0.05). There were no statistically significant differences in the percentage of time of NI value maintained in the target range, postoperative recovery time and incidence of adverse reactions between the two groups ( P>0.05). Conclusions:Adjusted NI value guidance combined with small-dose esketamine provides better efficacy when used for program-controlled closed-loop TCI system.

Objective:To investigate the effects of Xiongcan Yishen Formula(XYF)on ferroptosis in mouse TM3 Leydig cells after oxidative stress injury(OSI)induced by H2O2.Methods:An oxidative stress injury model was established in mouse TM3 Leydig cells using H2O2 induction.The modeled TM3 cells were randomly divided into OSI group,XYF group,the ferroptosis inhibitor Ferrostatin-1(F-1)group,and F-1+XYF group,which were respectively intervened with blank serum,20%drug-containing serum,2μmol/L F-1,and2μmol/L F-1+20%drug-containing serum.A control group(normal TM3 cells+blank serum)was also set up.The morphology of cells in each group was observed,and the levels of testosterone,superoxide dismutase(SOD),reactive oxygen spe-cies(ROS),malondialdehyde(MDA),ferritin heavy chain 1(FTH1),solute carrier family 7 member 11(SLC7A11),glutathione(GSH),glutathione peroxidase 4(GPX4),fatty acid CoA ligase 4(FACL4),total iron ions,and ferrous ions were detected.Re-sults:Compared with the model group,the control group showed significantly decreased expression of ROS,MDA,FACL4,total iron,and ferrous ions(P<0.05),and significantly increased levels of testosterone,SOD,GSH,FTH1,SLC7A11,and GPX4(P<0.05).The male silkworm kidney-tonifying formula group significantly promoted testosterone secretion by TM3 cells and upregulated the expression of FTH1,SLC7A11,GPX4,GSH,and SOD in TM3 cells(P<0.05),while significantly downregulating ROS,MDA,FACL4,total iron ions,and ferrous ions(P<0.05).Conclusion:Following H2O2 exposure,oxidative stress can induce ferroptosis in mouse TM3 Leydig cells.XYF can antagonize OSI and ferroptosis in TM3 cells by activating the SLC7A11/GSH/GPX4 axis,which may underlie the mechanism of XYF in the treatment of male late-onset hypogonadism.

Objective:To investigate the correlation between complement C3 and urine protein level and proteinuria remission status in patients with primary membranous nephropathy (PMN), and better guide individualized clinical treatment.Methods:It was a single-center retrospective study. The clinical data of PMN patients who underwent renal biopsy in the First Affiliated Hospital of Nanjing Medical University from January 2017 to June 2022 were collected. Patients with 24 h urinary protein ≥ 3.5 g were followed up after receiving standard treatment, and the last outpatient or inpatient review was used as the end point of follow-up. 24 h urine protein was collected to evaluate the remission status of proteinuria. Kaplan-Meier method was used to analyze the correlation between serum and renal complements and proteinuria remission. Cox regression analysis method was used to analyze the correlation between serum C3 level and renal tissue C3 deposition and proteinuria remission.Results:This study included 507 PMN patients with 312 (61.54%) males, aged 54 (43, 64) years old. Compared with 24 h urinary protein < 3.5 g group, proportion of males ( χ2=22.479, P<0.001), age ( Z=-2.521, P=0.012), systolic blood pressure ( Z=-4.148, P<0.001), diastolic blood pressure ( Z=-4.084, P<0.001), serum anti-phospholipase A2 receptor (PLA2R) antibody titer ( Z=-7.019, P<0.001), total cholesterol ( Z=-8.796, P<0.001), triglyceride ( Z=-6.158, P<0.001), low density lipoprotein cholesterol ( Z=-8.716, P<0.001), serum creatinine ( Z=-7.368, P<0.001), serum C3 ( Z=-3.663, P<0.001), serum C4 ( Z=-6.560, P<0.001), proportion of glucocorticoid use ( χ2=116.417, P<0.001) and proportion of immunosuppressant use ( χ2=53.839, P<0.001) were all higher, while serum albumin ( Z=12.518, P<0.001), estimated glomerular filtration rate ( Z=6.345, P<0.001) and serum IgG ( Z=7.321, P<0.001) were all lower in 24 h urinary protein ≥3.5 g group. There were 268 patients included in the follow-up cohort with baseline 24 h urinary protein of 7.15 (5.14, 10.24) g, serum anti-PLA2R antibody titer of 61.44 (14.35, 193.24) RU/ml, serum C3 of 1.005 (0.864, 1.150) g/L, and serum C4 of 0.260 (0.214, 0.317) g/L. Kaplan-Meier survival curve showed that the incomplete remission rate of proteinuria in serum C3 > 1.005 g/L group was lower than that in serum C3 ≤ 1.005 g/L group (log-rank χ2=4.757, P=0.029). There was no significant difference in the incomplete remission rate of proteinuria between serum C4 ≤ 0.260 g/L group and serum C4 > 0.260 g/L group (log-rank χ2=3.543, P=0.060). Renal C1q (log-rank χ2=0.167, P=0.683) and C4 (log-rank χ2=1.927, P=0.165) deposition had no significant effects on proteinuria remission in PMN patients. The incomplete remission rate of proteinuria in patients with renal C3 deposition was higher than that in patients without renal C3 deposition (log-rank χ2=7.018, P=0.008). Univariate Cox regression analysis showed that serum C3 level and C3 deposition in renal tissues were influencing factors of incomplete remission of proteinuria (both P<0.05), while adjusting for gender, age, mean arterial pressure, serum anti-PLA2R antibody, serum albumin and 24 h urinary protein, serum C3 ≤ 1.005 g/L ( HR=1.374, 95% CI 1.021-1.849, P=0.036), C3 deposition in renal tissues ( HR=1.949, 95% CI 1.098-3.460, P=0.023), and serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues ( HR=1.472, 95% CI 1.093-1.983, P=0.011) were independent influencing factors of incomplete remission of proteinuria. Conclusions:The serum C3 level and C3 deposition in renal tissues are closely related to urinary protein level and proteinuria remission status in PMN patients. The patients with higher urinary protein have higher serum C3. For patients with massive proteinuria, serum C3 ≤ 1.005 g/L, C3 deposition in renal tissues, serum C3 ≤ 1.005 g/L combined with C3 deposition in renal tissues are independent risk factors of incomplete remission of proteinuria.

Objective To investigate the correlation between serum Irisin,long pentraxin 3(PTX3),human metas-tasis-associated lung adenocarcinoma transcript 1(MALAT1)levels and the severity of diabetic retinopathy(DR)and the value of combined diagnosis.Methods Eighty-five patients with type 2 diabetes mellitus(T2DM)combined with DR at Cangzhou Central Hospital from April 2022 to April 2023 were selected as the DR group,85 patients with T2DM alone were selected as the non-DR group,and 85 healthy volunteers were selected as the control group during the same period.Pa-tients in the DR group were further divided into the proliferative DR(PDR)group(38 patients)and the non-PDR group(47 patients)based on whether DR was in the proliferative phase.Clinical data of patients in the DR group were collected,including gender,diastolic pressure,age,systolic pressure,disease course,fasting plasma glucose(FPG),body mass in-dex,hemoglobin A1c(HbA1c),smoking history,triglyceride(TG),drinking history,peak systolic velocity(PSV),peak end-diastolic velocity(PEDV),resistance index(RI),fasting insulin(FINS),family history of diabetes,total cholesterol(TC),and homa-insulin resistance(HOMA-IR).Enzyme-linked immunosorbent assay was used to detect serum levels of Irisin and PTX3 in each group of patients,and real-time quantitative polymerase chain reaction was used to detect the ser-um level of MALAT1.The correlations between serum levels of Irisin,PTX3 and MALAT1 and the severity of DR were ana-lyzed using the Pearson correlation coefficient.The influencing factors of the DR severity were identified using the Logistic regression.The value of serum Irisin,PTX3,and MALAT1 levels in diagnosing DR alone was analyzed using the receiver operating characteristic(ROC)curve.The value of regimens containing and not containing serum Irisin,PTX3,and MAL-AT1 levels in diagnosing DR was analyzed using the ROC curve,net reclassification index(NRI),and integrated discrimina-tion improvement(IDI)index.Results The serum levels of Irisin,PTX3,and MALAT1 were compared among the three groups of patients,and the differences were statistically significant(all P＜0.001).The disease course of patients in the PDR group was longer than that in the non-PDR group,the PSV,PEDV and serum Irisin level were lower than those in the non-PDR group,while the RI,FPG,HbA1c,TG,FINS,HOMA-IR,and serum PTX3 and MALAT1 levels were higher than those in the non-PDR group(all P＜0.05).The serum Irisin level in DR patients was negatively correlated with the severity of DR(r=-0.512,P＜0.001),while the PTX3 and MALAT1 levels were positively correlated with the severity of DR(r=0.497,0.573,both P＜0.05).The Logistic regression analysis showed that the disease course,FPG,HbA1c,TG,FINS,HOMA-IR,PSV,PEDV,RI,and serum levels of Irisin,PTX3 and MALAT1 were influencing factors for the DR progression(allP＜0.05).The area under the curve(AUC)of serum Irisin,PTX3,and MALAT1 levels in diagnosing DR was 0.743,0.811,and 0.773,respectively.Compared with conventional diagnostic protocols,the AUC of the new diagnostic protocol containing serum levels of Irisin,PTX3,and MALAT1 significantly increased(Z=2.708,P=0.007),and the NRI and IDI were 0.039(95％CI:0.022-0.069)and 0.026(95％CI:0.014-0.047),respectively(all P＜0.05).Conclusion The serum Irisin level in DR patients decreases,while the serum PTX3 and MALAT1 levels increase,which are closely related to the severity of DR.Diagnostic plans containing serum Irisin,PTX3,and MALAT1 indicators have high diagnostic value.
