OBJECTIVE:Neuromuscular exercise is a new comprehensive rehabilitation therapy in recent years,but its effect on knee osteoarthritis is still controversial.The purpose of this paper is to systematically evaluate the efficacy of neuromuscular exercise on knee osteoarthritis pain and function. METHODS:The randomized controlled trials addressing neuromuscular exercise in the treatment of knee osteoarthritis pain and function were retrieved from PubMed,Cochrane Library,Embase,EBSCO,CNKI,Web of Science,China Biomedical Database(CBM),VIP,and WanFang Database.The retrieval time ranged from database inception to October 2023.The neuromuscular training group(experimental group)was given neuromuscular training or neuromuscular training as the main intervention;the control group was a blank group or given conventional rehabilitation.Outcome indicators included the Western Ontario and McMaster Universities Osteoarthritis Index(WOMAC)score,walking time,knee stability,and the maximum number of knee flexion in 30 seconds.The risk of bias was evaluated by the Cochrane Collaboration tool and the Physiotherapy Evidence Database.Meta-analysis was performed using RevMan 5.4 software. RESULTS:A total of 11 randomized controlled trials were included,and 628 samples were extracted.The results of Meta-analysis showed that the experimental group was superior to the control group in terms of WOMAC pain score[standardized mean difference(SMD)=0.38,95%confidence interval(CI):0.08-0.69,P=0.01],knee stability(SMD=0.57,95%CI:0.23-0.92,P=0.001),the maximum number of knee joint flexion in 30 seconds(SMD=0.35,95%CI:0.05-0.65,P=0.02),and WOMAC physical function score(SMD=-0.79,95%CI:-1.30 to-0.28,P=0.002).In both groups,walking speed was increased and walking ability was improved in patients with knee osteoarthritis,but there was no significant difference(walking time:SMD=-0.22,95%CI:-0.48-0.03,P=0.09). CONCLUSION:Neuromuscular exercise can effectively improve knee joint pain,enhance the stability of the knee joint,and promote functional recovery in patients with knee osteoarthritis.However,more high-quality randomized controlled trials are still needed to further confirm the research.

OBJECTIVE:At present,there are a variety of treatment methods for scoliosis using specific exercise therapy,but there is a lack of comparison of efficacy between different specific exercise therapy.This article compared the effectiveness of different specific exercise therapies to treat adolescent idiopathic scoliosis through a network meta-analysis. METHODS:Domestic and foreign electronic databases of relevant studies were searched for randomized controlled trials of specific exercise therapy for adolescent idiopathic scoliosis.Search time was from January 2000 to July 2023.The literature was screened by two reviewers using RevMan 5.4 and Stata 16.0 software to extract data and assess the bias risk of of inclusion studies. RESULTS:(1)This article includes 20 randomized controlled trials with 1 377 patients.Of them,12 studies involved Schroth therapy;2 studies involved BSPTS therapy,and 6 studies involved SEAS therapy.(2)The network meta-analysis indicated that in terms of improving Cobb angle and reducing trunk rotation angle in scoliosis patients,the BSPTS therapy group and Schroth therapy group were better than the conventional control group[WMD=-4.60,95%CI(-8.37,-0.82),P<0.05;WMD=-3.37,95%CI(-4.98,-1.75),P<0.05;WMD=-3.20,95%CI(-5.50,-0.90),P<0.05;WMD=-2.13,95%CI(-3.16,-1.09),P<0.05].The Schroth therapy group performed better than the conventional control group effective in improving the International Society for Scoliosis Research-22 Questionnaire quality of life score[WMD=1.41,95%CI(0.07,2.75),P<0.05]. CONCLUSION:Given the current evidence,BSPTS therapy group and Schroth therapy group were better than the conventional control group in improving Cobb angle and reducing trunk rotation angle.In the comparison of different specific exercise therapies,BSPTS therapy can be preferred to improve Cobb angle and reduce trunk rotation angle in adolescent idiopathic scoliosis patients.In addition,Schroth therapy may be the best treatment to improve the quality of life of adolescent idiopathic scoliosis patients.Limited by the quantity and quality of the included studies,the above conclusions should be interpreted with caution and need more high-quality studies to further validation.

Objective To explore the value of pelvic CT angiography(CTA)digital three-dimensional reconstruction model(abbreviated as"three-dimensional model")in the diagnosis of female pelvic mass.Methods A total of 98 patients with pelvic mass who were hospitalized and operated in Xi'an People's Hos-pital(Xi'an Fourth Hospital)from January 2021 to April 2023 were selected.All patients underwent B-ultra-sound and CTA examination before operation,and the original data of CTA were collected.The digital three-dimensional model of pelvic mass was established by three-dimensional reconstruction software,and the source of pelvic mass was judged according to the blood supply of pelvic mass.Taking postoperative pathological di-agnosis as the gold standard,the coincidence rate between different preoperative diagnosis methods(B-ultra-sound,CTA examination and three-dimensional model)was compared.The receiver operating characteristic(ROC)curve was plotted to evaluate the efficacy of different preoperative diagnostic methods in judging the ovarian origin of pelvic tumors.Results A total of 130 pelvic masses were included in 98 patients,and the average maximum diameter of the mass was(71.61±3.03)mm,including 83 ovarian masses and 47 non-ovarian masses.Taking postoperative pathological diagnosis as the gold standard,the diagnostic coincidence rate of the preoperative three-dimensional model was 72.31％,which was higher than that of B-ultrasound(58.46％)and CTA(52.31％),and the differences were statistically significant(P＜0.001).The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,Kappa value,and area under the ROC curve were 79.51％,91.49％,94.29％,71.67％,83.85％,0.67 and 0.855,respectively,when the three-dimensional model showed that the blood supply of the mass originated from ovarian artery or uterine artery-ovarian branch.Conclusion The three-dimensional model of pelvic CTA can directly display the blood supply source,characteristics of mass,and the relationship between mass and adjacent organs,which can guide the clinical treatment.It has certain clinical value to judge the ovarian origin of pelvic mass by using ovarian artery and uterine artery-ovarian branch.

Objective To investigate the effect of rehabilitation instruction based on resourceful theory on the execution intention of exercise behaviour in patient with the first-episode stroke.Methods From September 2022 to February 2023,a total of 80 inpatients with first-episode stroke from a general hospital in Anhui Province participated in the study.Patients in Wards Ⅰ and Ⅱ were assigned to an intervention group,while those in Wards Ⅲ and Ⅳ were assigned to a control group,with 40 patients per group.The patients in control group received standard interventions,while those in the intervention group were offered with a rehabilitation instruction based on resourceful theory in addition to the standard interventions.Stroke patient rehabilitation exercise behaviour execution intention questionnaire,resourcefulness scale and modified Barthel were employed for assessments before and after the intervention.Results After the intervention,the intervention group showed significantly higher scores inexecutive intention of exercise behaviour,resourcefulness level and daily living activities compared to those in the control group(all P＜0.01).Conclusion Rehabilitation instruction based on the theory of resourcefulness can effectively increase the executive intention of exercise behaviour in the patients with first-episode stroke,improve the resourcefulness thinking levels and enhance the daily living activity of the patients.

Objective:To construct a prediction model for peripherally inserted central catheter-related upper extremity deep vein thrombosis (PICC-UEDVT) in patients with traumatic brain injury (TBI) and validate its effectiveness.Methods:A case-control study was conducted on the clinical data of 222 TBI patients admitted to Xiangya Hospital of Central South University from January 2019 to December 2021, including 171 males and 51 females, aged 18-86 years [54.5(46.0, 65.0)years]. Glasgow coma scale (GCS) motor score was 4.0(3.0, 5.0)points on the day of catheterization. A total of 82 patients (36.9%) had PICC-UEDVT. The patients were randomly divided with a ratio of 7∶3 into training set ( n=156, including 58 with PICC-UEDVT) and validation set ( n=66, including 24 with PICC-UEDVT) using R programming language. The baseline data of general information, intravenous medication, catheterization, and laboratory indices were compared between the training set and the validation set. Lasso regression analysis was employed to identify those variables, with the diagnosis of PICC-UEDVT as the outcome variable. Variables with non-zero regression coefficients were included in a multifactorial Logistic regression model and independent variables were selected based on the Akaike Information Criterion (AIC) of R programming language. The regression equation was constructed, based on which, the predictive nomogram model was constructed for PICC-UEDVT in TBI patients. Receiver operating characteristic (ROC) curves for the training set and validation set were plotted and the discriminability of the model was assessed. The calibration of the model was evaluated using the Hosmer-Lemeshow (H-L) goodness-of-fit test and calibration curves and the clinical practicality of the model was assessed with decision curve analysis (DCA). Results:The baseline analysis of both the training set and the validation set demonstrated a well-balanced sample distribution. Through Lasso regression analysis, 5 prediction variables were identified: GCS motor score on the day of catheterization, Caprini score on the day of catheterization, use of glucocorticoids, tip position of the catheter, and D-dimer (D-D) level before catheterization. The multivariate Logistic regression analysis revealed that the Caprini score on the day of catheterization ( OR=1.20, 95% CI 1.08, 1.33), use of glucocorticoids ( OR=3.13, 95% CI 0.99, 10.46), and D-D level before catheterization ( OR=1.16, 95% CI 1.07, 1.33) were independent risk factors for PICC-UEDVT in TBI patients. The regression equation was developed as: Logit [ P/(1- P)]=-2.56+0.18×"Caprini score on the day of catheterization"+1.14×"use of glucocorticoids"+0.15×"D-D level before catheterization". In the prediction model which was constructed based on the equation, the AUC values for the training set and validation set were 0.73 (95% CI 0.65, 0.81) and 0.77 (95% CI 0.65, 0.87) respectively. The H-L goodness-of-fit test indicated χ2=3.28, P=0.950 for the training set and χ2=13.05, P=0.160 for the validation set. Calibration curves for both sets demonstrated alignment between the actual and predicted probabilities of PICC-UEDVT in TBI patients. DCA results showed that the net benefit rate of patients was optimal when the threshold probability ranged from 15% to 72% for the training set and from 10% to 81% for the validation set. Conclusion:The prediction model based on the Caprini score on the day of catheterization, use of glucocorticoids, and D-D level before catheterization demonstrates good predictive accuracy, calibration and clinical practicality in predicting PICC-UEDVT in TBI patients.

Objective To compare the efficacy of MRI-transrectal ultrasound(TRUS)software fusion-guided biopsy and cognitive fusion-guided biopsy for detecting prostate cancer(PC).Methods Data of 120 patients with suspected PC(127 lesions)who underwent transperineal prostate biopsy with 2-3 times of target biopsy(TB)and 10 times of system biopsy were retrospectively analyzed.According to TB guidance methods,73 cases(78 lesions)received MRI-TRUS software fusion-guided biopsy were classified into group A,and 47 cases(49 lesions)received cognitive fusion-guided biopsy were classified into group B.The positive rate of PC,clinic significant PC(csPC)and PC in different sized lesions by TB were compared between groups,and the positive rate of PC between 2 or 3 times TB was also compared within each group.Results The positive rate of PC and csPC detected by TB was 55.13%(43/78)and 39.74%(31/78)in group A,53.06%(26/49)and 34.69%(17/49)in group B,respectively,no significant difference was found(all P＞0.05).The positive rate of PC in lesions with the maximum diameter≤10 mm detected by TB in group A was higher than that in group B(P＜0.05),but no significant difference of lesions with the maximum diameter＞10 mm and＜15 mm nor≥15 mm was found between groups(all P＞0.05).No significant difference of positive rate of PC was found between 2 and 3 times TB in group A(P＞0.05),while positive rate of PC of 3 times TB was significantly higher than that of 2 times TB in group B(P＜0.05).Conclusion MRI-TRUS software fusion-guided biopsy had positive rate of PC and csPC similar to that of cognitive fusion-guided biopsy,but was helpful for reducing times of TB and increasing detecting rate for lesions with the maximum diameter≤10 mm.

Objective To investigate the effect of the protein kinase RNA-like endoplasmic reticulum kinase(PERK)/eukaryotic initiation factor 2α(eIF2α)pathway in endoplasmic reticulum stress on the activation of hepatic stellate cells(HSC).Methods Pathological sections of normal liver tissue after surgery were collected from 11 patients with hepatic fibrosis(S1-S4)and 9 patients with hepatic hemangioma and hepatic adenoma confirmed by liver biopsy,and immunohistochemistry was used to measure the protein expression levels of PERK,eIF2α,and C/EBP homologous protein(CHOP).Human HSC-LX2 cells were treated with different concentrations of the endoplasmic reticulum stress inducer thapsigargin(0,125,250,500,and 1 000 nmol/L),and qRT-PCR was used to measure the mRNA expression level of PERK,while Western blot was used to measure the protein expression levels of PERK,inositol requiring protein 1(IRE1),activating transcription factor 6(ATF6),CHOP,and α-smooth muscle actin(α-SMA).The method of lentivirus transfection was used to construct a PERK stable overexpression LX-2 group and a control group;qRT-PCR was used to measure the mRNA expression levels of PERK,eIF2α,and α-SMA,Western blot was used to measure the protein expression levels of PERK,phosphorylated eIF2α(p-eIF2α),and α-SMA,and immunofluorescence assay was used to measure the expression of collagen type Ⅰ alpha 1(COL1A1).The independent samples t-test was used for comparison of normally distributed continuous data between two groups;a one-way analysis of variance was used for comparison between multiple groups,and the least significant difference t-test was used for further comparison between two groups.The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups.Results Compared with normal liver tissue,the liver tissue of patients with hepatic fibrosis had significantly higher expression levels of PERK,eIF2α,and CHOP(Z=-3.56,t=-5.75,Z=-3.52,all P<0.001).Compared with the solvent group,the groups treated with different concentrations of thapsigargin had significant increases in the expression levels of the endoplasmic reticulum-associated proteins PERK,CHOP,IRE1,ATF6,and α-SMA(all P<0.05).Compared with the control group,the PERK stable overexpression group had significant increases in the mRNA expression levels of PERK,eIF2α,and α-SMA and the protein expression levels of PERK,p-eIF2α,and α-SMA(all P<0.05),and immunofluorescence assay showed a significant increase in the expression level of COL1A1 in the PERK stable overexpression group(P<0.05).Conclusion PERK overexpression can induce the expression of α-SMA and COL1A1 in LX-2 cells,suggesting that the PERK signaling pathway might be one of the important mechanisms of HSC activation.

Objective:To analyze the image characteristics of gastrointestinal stromal tumor(GIST) and leiomyoma under white-light endoscopy and ultrasound endoscopy, so as to establish a nomogram model and to validate its performance.Methods:From August 1, 2019, to December 1, 2022, the clinical data of 224 patients with GIST or leiomyoma who underwent endoscopic ultrasound examination at the First Affiliated Hospital of Soochow University were retrospectively analyzed. The 224 patients were divided into the modeling group of 145 cases (78 cases of GIST and 67 cases of leiomyoma), and the validation group of 79 cases (41 cases of GIST and 38 cases of leiomyoma). The basic data of patients, parameters of white-light endoscopy and ultrasound endoscopy were screened to establish a binary logistic regression model and draw a nomogram. The receiver operating characteristic curve (ROC) was drawn, and the area under the curve (AUC) was used to evaluate the diagnostic efficiency of the model, and calibration curve was used to evaluate the consistency of predicted and observed probabilities. The model′s performance was compared with the diagnostic results of junior physicians (attending physicians) and senior physicians (associated chief physician). Decision curve analysis (DCA) was performed to evaluate the net benefit of the model. Independent sample t-test and chi-square test were used for statistical analysis. Results:Under white-light endoscopy, there were statistically significant differences in the lesion locations (esophagus: 0 vs. 56.7% (38/67); cardia: 11.5% (9/78) vs. 13.4% (9/67); gastric: 88.5% (69/78) vs. 29.9% (20/67)) and tumor morphyology (spherical or spheroid: 80.8% (63/78) vs. 28.4% (19/67); shuttle: 19.2% (15/78) vs. 71.6% (48/67)) between GIST and leiomyoma in the modeling group ( χ2=64.51 and 46.37, both P<0.001). Under ultrasound endoscopy, the proportion of patients with GIST whose lesions originated from the muscularis propria layer, with indistinct borders and with internal hyperechoic area were all higher than those of patients with leiomyoma (96.2% (75/78) vs. 62.7% (42/67); 53.8% (42/78) vs. 13.4% (9/67); 35.9% (28/78) vs. 10.4% (7/67)), and the differences were statistically significant ( χ2=25.91, 25.82 and 12.75, all P<0.001). Based on the logistic regression model, a nomogram model was established with age, tumor morphology, lesion origin, boundary clarity, and hyperechoic foci as predictive indicators. In the modeling group, the accuracy of nomogram model in the diagnosis of GIST and leiomyoma was 89.7% and 83.6%, respectively. In the validation group, the sensitivity, specificity, and accuracy in GIST and leiomyoma diagnosis of the nomogram model and senior physicians were all higher than those of junior physicians in differentiating GIST from leiomyoma (90.2%, 87.8% vs. 82.9%; 81.6%, 84.2% vs. 78.9%; 86.1%, 86.1% vs. 81.0%, respectively), and the sensitivity, specificity, and accuracy of the nomogram model were equal to those of senior physicians in differentiating GIST from leiomyoma. The AUCs of the nomogram model in the modeling group and validation group were 0.932 (95% confidence interval 0.891 to 0.974) and 0.916 (95% confidence interval 0.854 to 0.978), respectively. The calibration curves of the model indicated that the consistency between the predicted probabilities and observed probabilities was good, and DCA suggested good clinical net benefits of the model. Conclusion:The model exhibits good test efficiency, discrimination, prediction consistency and clinical net benefit when age, tumor morphology, lesion origin, boundary clarity, and hyperechoic foci are selected as indicators.

Objective To investigate the therapeutic effect of Zuojin Jiawei Formula combined with acupuncture and moxibustion in gastroesophageal reflux disease (GERD) of liver-stomach stagnation heat type and its impact on brain-gut peptides. Methods A total of 160 patients with GERD of liver-stomach stagnation heat type who were diagnosed and treated at the outpatient department of spleen and stomach of Yangzhou Hospital of Traditional Chinese Medicine from July 2021 to December 2022 were randomly divided into four groups: western medicine group, traditional Chinese medicine group, acupuncture group, and traditional Chinese medicine combined with acupuncture group, with 40 patients in each group. The western medicine group was treated with rabeprazole as the main drug, the traditional Chinese medicine group was treated with Zuojin Jiawei Formula alone, the traditional Chinese medicine combined with acupuncture group was treated with acupuncture at Zusanli, Zhongwan, Taichong, and Neiguan on the basis of Zuojin Jiawei Formula, and the acupuncture group was treated with acupuncture at Zusanli, Zhongwan, Taichong, and Neiguan alone. All four groups were treated for 8 weeks, and the clinical efficacy along with Reflux Disease Questionnaire score, main symptoms score of traditional Chinese medicine, esophageal mucosa score, and vasoactive intestinal peptide level before and after treatment were compared among the four groups. Results After treatment, the total effective rate of the traditional Chinese medicine combined with acupuncture group was higher than the other three groups, and the scores of main symptoms of traditional Chinese medicine, Reflux Disease Questionnaire score, esophageal mucosa score, and plasma vasoactive intestinal peptide levels were lower than the other three groups and before treatment(P < 0.05). Conclusion Zuojin Jiawei Formula combined with acupuncture can effectively alleviate the clinical symptoms of GERD, promote mucosal healing, and improve treatment outcomes.

Objective:To analyze the disease spectrum of lysosomal storage disorders(LSDs) and explore the prevalent distributions of different LSD types in one center in Shanghai.Methods:A retrospective analysis was made.A total of 5 476 suspected LSD patients, including 3 415 males and 2 061 females, with a median age of 4 years(1 day to 72 years), were collected from Xinhua Hospital, Shanghai Jiaotong University School of Medicine from August 2008 to May 2022.The activity of different lysosomal enzymes was detected by fluorescent and biochemical methods.Results:A total of 1 520 patients were diagnosed with LSDs, including 972 males and 548 females, with a median age of 4 years(1 day to 59 years), involving 19 different subtypes.Mucopolysaccharidosis(MPS) was the most common type among LSDs, with a frequency of 45.46%(691/1 520), followed by sphingolipidoses [33.88%(515/1 520)] and glycogen storage disease type Ⅱ [16.05%(244/1 520)] successively.MPS Ⅱ was the most common type in MPS, with a frequency of 45.73%(316/691), followed by MPS ⅣA [22.87%(158/691)]. Niemann-Pick A/B, Gaucher, and Krabbe diseases were common in Sphingolipidoses patients, with frequencies of 37.09%(191/515), 34.37%(177/515), and 10.29%(53/515), respectively.Conclusions:LSDs are common genetic metabolic diseases, especially MPS and sphingolipidoses.Newborn screening for LSDs should be carried out timely so that the patients can be treated early and their prognosis can be improved.
