BACKGROUND: The effects of acupuncture have varied in different randomized controlled trials (RCTs), and there are many factors that influence treatment effect of acupuncture in different outcomes, with conflicting results. OBJECTIVE: To identify factors and their impact on the treatment effect of acupuncture in different outcomes. METHODS: Acupuncture RCTs were searched from 7 databases including Medline (PubMed), Embase, Cochrane Central Register of Controlled Trials, China National Knowledge Infrastructure, Wanfang Database, VIP Database, and China Biology Medicine disc between January 1st, 2015 and December 31st, 2019. Eligible studies must compare acupuncture to no acupuncture, sham acupuncture, or waiting lists, and report at least 1 patient-important outcome. A multi-level meta-regression was conducted using a 3-level robust mixed model and univariate analyses were performed for all independent variables, even those excluded from the multivariable model due to collinearities. We used thresholds of 0.2 and 0.4 for the difference of standardized mean differences (SMDs), categorising them as small (<0.2), moderate (0.2-0.4), or large (>0.4) effects. RESULTS: The pain construct analysis involved 211 effect estimates from 153 studies and 14 independent variables. High-frequency acupuncture treatment sessions produced larger effects compared to low-frequency sessions [large magnitude, the difference of adjusted SMDs 0.46, 95% confidence interval (CI) 0.07 to 0.84; P=0.02]. The non-pain symptoms construct analysis comprised 323 effect estimates from 231 studies and 15 independent variables. Penetrating acupuncture showed moderately larger effects when compared to non-penetrating acupuncture (0.30, 95% CI 0.06 to 0.53; P=0.01). The function construct analysis included 495 effect estimates from 274 studies and 14 independent variables. Penetrating acupuncture and the flexible acupuncture regimen showed moderately larger effects, compared to non-penetrating acupuncture and fixed regimen, respectively (0.40, 95% CI 0 to 0.80; P=0.05; 0.29, 95% CI 0.06 to 0.53; P=0.01). CONCLUSIONS High-frequency acupuncture sessions appear to be a more effective approach to managing painful symptoms. Penetrating acupuncture demonstrated greater effect in relieving non-painful symptoms. Both penetrating acupuncture type and flexible acupuncture regimen were linked to significant treatment effects in function outcomes. Future studies should consider the factors that are significantly associated with the effects of acupuncture in patient-important outcomes.

Objective To observe the alteration of thoracic and lumbar physiological curvature in adolescent idiopathic scoliosis(AIS)and the difference of physiological curvature between different types of scoliosis.Methods A retrospective analysis was conducted on 305 adolescent patients taken full spine X-ray in our hospital from January 2017 to December 2021.The patients were divided into normal group and scoliosis group.The normal group was composed of 179 patients,79 males and 100 females,aged 10 to 18 years old with an average of(12.84±2.10)years old,with cobb agle less than 10 degrees.The scol-iosis group was composed of 126 patients,33 males and 93 females,aged 10 to 18 years old with an average of(13.92±2.20)years old.The gender,age,Risser sign,thoracic kyphosis(TK)and lumbar lordosis(LL)in 2 groups were compared,and the TK and LL were also compared between different genders,different degrees of scoliosis and different segments of scoliosis.Re-sults The female ratio(P=0.001)and age(P＜0.001)in scoliosis group were higher than them in normal group;the ratio of low-grade ossification was higher in normal group than in scoliosis group(P=0.038).TK was significantly smaller in scoliosis group than in normal group(P＜0.001),but there was no significant difference in LL between the 2 groups(P=0.147).There were no significant difference in TK and LL between male and female.The TK was significantly bigger in mild AIS patients than in moderate AIS patients(P＜0.05),but there was no significant difference in LL between mild and moderate patients(P＞0.05).The TK and LL in different segments scoliosis were not found significant difference.Conclusion The physiological curvature of thoracic and lumbar spine is independent of gender.The thoracic physiological curvature becomes smaller in AIS patients,but lumbar curvature remains unchanged.The thoracic physiological curvature in mild AIS patients is greater than that in moderate AIS patients,but the lumbar curvature is almost unchanged between mild and moderate scoliosis and is similar with that in normal adolescent.The alteration of thoracic and lumbar physiological curvature in AIS patients may be related to relative an-terior spinal overgrowth,and the specific detailed mechanism needs to be further studied.

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

Electrochemiluminescence(ECL)refers to the process of luminescence triggered by high-energy electron transfer between intermediate products during the oxidation-reduction reaction on the electrode surface.In the co-reactants involved ECL process,the presence of co-reaction accelerators can effectively catalyze the decomposition of co-reactants,leading to the generation of abundant free radical intermediates,thereby significantly enhancing the ECL signals.This plays a critical role in constructing simple,sensitive,and efficient ECL sensing platforms.This review focused on the novel co-reaction accelerators developed in recent years.Based on different types of co-reaction accelerator materials,including single atom catalysts,metal-based nanomaterials,polymers and other materials,the ECL reaction process and signal enhancement mechanisms,as well as their relevant applications in constructing ECL sensing platforms,were elucidated.Furthermore,the current research challenges and development prospect of co-reaction accelerators were also discussed.

Objective To explore the postmortem diffusion rule of Aconitum alkaloids and their metabo-lites in poisoned rabbits,and to provide a reference for identifying the antemortem poisoning or post-mortem poisoning of Aconitum alkaloids.Methods Twenty-four rabbits were sacrificed by tracheal clamps.After 1 hour,the rabbits were administered with aconitine LD50 in decocting aconite root powder by intragastric administration.Then,they were placed supine and stored at 25℃.The biological samples from 3 randomly selected rabbits were collected including heart blood,peripheral blood,urine,heart,liver,spleen,lung and kidney tissues at 0 h,4 h,8 h,12 h,24 h,48 h,72 h and 96 h after intragastric administration,respectively.Aconitum alkaloids and their metabolites in the biological samples were ana-lyzed by high performance liquid chromatography-tandem mass spectrometry(HPLC-MS/MS).Results At 4 h after intragastric administration,Aconitum alkaloids and their metabolites could be detected in heart blood,peripheral blood and major organs,and the contents of them changed dynamically with the preservation time.The contents of Aconitum alkaloids and their metabolites were higher in the spleen,liver and lung,especially in the spleen which was closer to the stomach.The average mass fraction of benzoylmesaconine metabolized in rabbit spleen was the highest at 48 h after intragastric administration.In contrast,the contents of Aconitum alkaloids and their metabolites in kidney were all lower.Aconi-tum alkaloids and their metabolites were not detected in urine.Conclusion Aconitum alkaloids and their metabolites have postmortem diffusion in poisoned rabbits,diffusing from high-content organs(stomach)to other major organs and tissues as well as the heart blood.The main mechanism is the dispersion along the concentration gradient,while urine is not affected by postmortem diffusion,which can be used as the basis for the identification of antemortem and postmortem Aconitum alkaloids poisoning.

Objective To investigate the independent risk factors of comprehensive complication index(CCI)≥26.2 after radical resection of colon cancer,and use these factors to establish and verify a dynamic web-based nomogram model.Methods The clinical data of colon cancer patients who underwent radical resection in the Affiliated Hospital of Jiangnan University from November 2020 to April 2022 were retrospectively collected,and divided into main cohort(November 2020 to October 2021,n=438)and validation cohort(November 2021 to April 2022,n=196).CCI scores of all patients were obtained based on CCI calculator(http://www.assessurgery.com).Univariate and multivariate logistic regression analysis were performed to identify the risk factors for CCI≥26.2,and a nomogram model was constructed.Receiver operator characteristic curve(ROC),C index and calibration curve were used to evaluate the differentiation and consistency of predictive nomogram model,and the decision curve analysis was conducted to assess the clinical benefits of the model.Internal validation of the model is performed in the validation cohort.Results A total of 438 patients were identified in present study,of which 63 cases(14.4%)had CCI≥26.2.Multivariate logistic regression analysis revealed that age≥60 years(OR=2.662,95%CI 1.341-5.285,P=0.005),low third lumbar spine skeletal muscle mass index(L3MI;OR=4.572,95%CI 2.435-8.583,P<0.001),NRS2002≥3(OR=4.281,95%CI 2.304-7.952,P<0.001),and preoperative bowel obstruction(OR=3.785,95%CI 1.971-7.268,P<0.001)were significant independent risk factors for postoperative CCI≥26.2.Based on these results,a static and web-based dynamic nomogram was established(https://jndxfsyywcwksyf.shinyapps.io/DynNomCCI/).The C-index and area under the curve(AUC)of the nomogram were 0.742 and 0.787,respectively.The calibration curve indicated a good consistency between the predicted probability and the actual probability.In the validation cohort,the nomogram also presented good discrimination(C-index=0.722,AUC=0.795)and predictive consistency.The decision curve analysis indicated the clinical benefit and application value of the nomogram prediction model.Conclusion This easy-to-use dynamic nomogram based on 4 independent risk factors can conveniently and reliably predict the probability of CCI≥26.2 after radical resection of colon cancer,which helps optimize the preoperative evaluation system,formulate precise individualized treatment strategies,and enhance recovery after surgery.

Purpose: In patients with acute left-sided colonic obstruction, stenting can convert an emergency operation into a semi-elective procedure. However, its use continues to be debated. We performed a cost-effective analysis using our institution’s experiences. Methods: Endoscopic, surgical, and financial details were prospectively collected for patients who presented with acute colonic obstruction and underwent stenting between 2019 and 2022. Outcomes were defined as technical/clinical success and successful surgical resection. The financial cost of stenting was compared with the expected cost without stenting. Results: Forty patients were included, with 29 undergoing definitive resection. The most common pathology was primary colon cancer (27 patients, 93%). Endoscopic stenting had high technical (90%) and clinical (83%) success rates, with low rates of complications such as perforation (2 patients, 7%) and migration (0 patients, 0%). As a bridge to surgery, the median procedure time was 226 minutes and the surgical outcomes also showed a low rate of complications (3 patients, 11%), such as anastomotic leakage (0 patients, 0%), intraabdominal abscesses (2 patients, 7%), and 30-day postoperative mortality (0 patients, 0%). The cumulative costs with colonic stenting were $32,900, while the expected costs with emergency surgery, including stoma reversal, were $40,700 (healthcare cost-savings of $7,800 per person). The difference was mainly due to the avoidance of upfront emergency surgery. The incremental cost-effectiveness ratio was 0.81, favoring colonic stenting over upfront emergency surgery. Conclusion Colonic stenting as a bridge to surgery is safe and cost-effective for treating left-sided colonic obstruction with high success rates and low complication rates.

bstract: Objective To elucidate the distribution characteristics of mosquito species and the population genetic diversity of important mosquito species in the Wuyi Mountain Nature Reserve, with the aim of providing a scientific basis for the prevention and control of mosquito-borne diseases in the region. Methods Within Wuyi Mountain Nature Reserve 2022- 2023, 16 sampling sites were selected, where larvae were collected using the pipette method and adult mosquitoes were collected using the mosquito trap lamp method. Mosquito species identification was accomplished by integrating morphological characteristics and molecular identification techniques based on CO Ⅰ and CO Ⅱ gene sequences. Software tools such as ClustalX, DnaSP v5.0, and Network v4.6.1.0 were utilized to analyze the genetic differentiation (Fst), gene flow (Nm) among populations of Aedes japonicus, Aedes albopictus and Armigeres subalbatus. Results The mosquito specimens collected from the Wuyi Mountain Nature Reserve were identified as 30 species belonging to 8 genera within the Culicidae family. Among them, there were 10 species of Aedes, 13 species of Culex, 1 species each of Armigeres, Orthopodomyia, Uranotaenia, Tripyeroides, and Anopheles, and 2 species of Toxorhynchites. Analysis of the genetic structure of important mosquito populations showed that the haplotype diversity index (Hd) of Ae. japonicus was 0.994 7, with a generally moderate degree of differentiation between populations and a higher degree of genetic differentiation between populations 6 and 12; Aedeslbopictus had a haplotype diversity index of 0.634 0, with significant genetic differentiation between populations 1 and 2 compared to other groups; Armigeres subalbatus had a haplotype diversity index of 0.703 3, with substantial genetic differentiation and limited gene flow between population 2 and populations 3, 4, 6, and 7. Conclusions The mosquito species are rich in Wuyi Mountain Nature Reserve. A comprehensive survey of the composition and distribution of mosquito populations was carried out, and the characteristics of the population genetic structure of the important species of Ae. japonicus, Ae. Albopictus, and Ar. subalbatus populations were analyzed, providing valuable scientific data reference for local mosquito-borne ecological research and disease prevention and control.
