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.

Cervical cancer is one of the most common gynecological malignant tumors in China. Given their lack of obviously early symptoms, more than half of patients with cervical cancer are diagnosed in the middle and late stages of this malignancy, resulting in poor prognosis. Finding new therapeutic targets is the current research direction. Metabolomics, as a new omics technology, is expected to provide new targets for tumor precision diagnosis and treatment through the analysis of the changes and potential mechanisms of metabolites in tumor occurrence and development by chromatography, mass spectrometry, and other technologies. Herein, we review the research methods of metabolomics; metabolic characteristics of cervical cancer; and progress of the research on metabolomics in cervical cancer diagnosis, curative effect prediction, and prognosis evaluation to provide new ideas for the precise diagnosis and treatment of cervical cancer.

ObjectiveTo explore the effects of Bushen Tiaojing Formula （补肾调经方） on the quality of early embryos in repeated controlled ovarian stimulation （COS） and its possible mechanism. MethodsA total of 150 ICR female mice were divided into a normal group， a model group， an inhibitor group， a low-dose and a high-dose Bushen Tiaojing Formula group. Mice in the normal group， inhibitor group and model group were gavaged with distilled water 0.25 ml a day， and mice in the low- and high-dose groups were given 25.6 and 51.2 g/（kg·d） of Bushen Tiaojing Formula， respectively. All groups were gavaged once a day for 13 days as a cycle. Mice in the normal group were injected intraperitoneally with 0.1 ml normal saline on the 11th day of gavage， while mice in the other four groups were used to establish COS models. The inhibitor group was injected with the endoplasmic reticulum stress inhibitor 4-phenylbutyric acid 0.2 ml one hour before modelling. All groups were injected by gavage and intraperitoneal injection for 3 consecutive cycles， with an interval of 4 days between cycles. Immediately after the third intraperitoneal injection， mice were grouped with male mice of the same strain in a ratio of 2∶1， and at 8AM of the second day， the mice were examined， and those with spermatozoa or spermatozoa in the vaginal smears were recorded as pregnant. The mice were executed in the afternoon of the 4th day of pregnancy， and the blastocysts were obtained under an inverted microscope. The morphology of the blastocysts was observed， and the total number of blastocysts and the number of high-quality blastocysts were recorded to calculate the rate of high-quality blastocysts； the apoptosis of blastocyst cells was detected by the Tunel method， and the apoptosis rate was calculated； the endoplasmic reticulum molecular chaperone protein glucose-regulated protein 78 （GRP78）， C/EBP homologous protein （CHOP）， B-lymphoblastoma 2 （Bcl-2）， Bcl-2-associated X protein （Bax）， cystathionin 3 （Caspase-3） and cystathionin 12 （Caspase-12） protein levels and their mRNA expression were detected by immunofluorescent assay and RT-qPCR assay， respectively. ResultsIn the normal group， blastocysts had regular morphology， good morphological development and low fragmentation rate； in the model group， blastocysts were poorly developed， cell morphology was irregular， fragmentation rate was high， and there was some stagnation； in the inhibitor group and high-dose， low-dose Bushen Tiaojing Formula groups， cell morphology could be seen to be better developed， with regular morphology and less fragmentation rate. Compared with the normal group， the rate of high-quality blastocysts in the model group reduced， the rate of apoptosis of blastocyst cells increased， the levels of GRP78， CHOP， Caspase-12， Caspase-3， Bax protein and its mRNA expression in blastocysts increased， while the level of Bcl-2 protein and its mRNA reduced （P＜0.01）. Compared with the model group， the rate of high-quality blastocysts increased， the rate of apoptosis of blastocysts decreased， the levels of GRP78， CHOP， Caspase-12， Caspase-3， Bax protein and their mRNA expression decreased， and the levels of Bcl-2 protein and its mRNA expression increased in the blastocysts in the inhibitor group and the high-dose and low-dose Bushen Tiaojing Formula groups （P＜0.01）. Compared with the inhibitor group， GRP78， CHOP， Caspase-12， Bax protein levels and their mRNA expressions increased in the high-dose Bushen Tiaojing Formula group， and Caspase-12， Caspase-3， Bax protein levels and their mRNA expressions increased in the low-dose formula group （P＜0.05 or P＜0.01）. ConclusionBushen Tiaojing Formula can inhibit the apoptosis of blastocyst cells caused by repeated controlled ovarian stimulation by improving endoplasmic reticulum stress， which plays a role in improving the quality of early embryos.

BACKGROUND: Lung adenocarcinoma is an important pathohistologic subtype of non-small cell lung cancer (NSCLC). Invasive non-mucinous pulmonary adenocarcinomas (INMA) tend to have a poor prognosis due to their significant heterogeneity and diverse histologic components. Establishing a histologic grading system for INMA is crucial for evaluating its malignancy. In 2021, the International Association for the Study of Lung Cancer (IASLC) proposed that a new histological grading system could better stratify the prognosis of INMA patients. The aim of this study was to establish a visualized nomogram model to predict INMA IASLC grading preoperatively by means of dual-energy computed tomography (DECT), fractal dimension (FD), clinical features and conventional CT parameters. METHODS: A total of 112 patients with INMA who underwent preoperative DECT were retrospectively enrolled from March 2021 to January 2025. Patients were categorized into low-intermediate grade and high grade groups based on IASLC grading. The clinical characteristics and conventional CT parameters, including baseline features, biochemical markers, and serum tumor markers, were collected. DECT-derived parameters, including iodine concentration (IC), effective atomic number (eff-Z), and normalized IC (NIC), were collected and determined as NIC ratio (NICr) and fractal dimension (FD). Univariate analysis was employed to compare differences in conventional characteristics and DECT parameters between the two groups. Variables demonstrating statistical significance were subsequently incorporated into a multivariate Logistic regression analysis. A nomogram model integrating clinical data, conventional CT parameters, and DECT parameters was developed to identify independent predictors for IASLC grading of INMA. The discriminatory performance of the model was evaluated using receiver operating characteristic (ROC) curve analysis. RESULTS: Multivariate analysis identified smoking history [odds ratio (OR)=2.848, P=0.041], lobulation sign (OR=2.163, P=0.004), air bronchogram (OR=7.833, P=0.005), eff-Z in arterial phase (OR=4.266, P<0.001), and IC in arterial phase (OR=1.290, P=0.012) as independent and significant predictors for IASLC grading of INMA. The nomogram model constructed based on these indicators demonstrated optimal predictive performance, achieving an area under the curve (AUC) of 0.804 (95%CI: 0.725-0.883), with specificity and sensitivity of 85.3% and 65.7%, respectively. CONCLUSIONS The nomogram model based on clinical features, imaging features and spectral CT parameters have a large potential for application in the preoperative noninvasive assessment of INMA IASLC grading.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

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.

Background Mitochondrial dynamin-related protein 1 (DRP1) regulates mitochondrial division and plays an important role in maintaining hepatocyte function. However, the role of DRP1 in cadmium exposure-induced maternal liver damage in pregnant mice remains unclear. Objective To investigate the role and mechanism of DRP1 in maternal liver damage induced by cadmium exposure during pregnancy. Methods This study consisted of animal experiments and cell experiments. (1) Animal experiments. Mice at 14 days of gestation were randomly divided into three groups: a control group, a low-dose cadmium group (LCd group: 2.5 mg·kg⁻¹), and a high-dose cadmium group (HCd group: 5 mg·kg⁻¹). The pregnant mice were intraperitoneally injected with cadmium chloride (CdCl₂) for 6 and 24 h in the next morning. The weights of pregnant mice, uterus, maternal liver, and fetal mice were recorded after sacrifice. Serum and liver of pregnant mice were collected, the levels of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in serum were detected, and liver tissues were stained with HE to observe changes in liver function and liver tissue structure. The expressions of oxidative phosphorylation-related proteins, hypoxia inducible factor-1α (HIF-1α) and DRP1 proteins in liver of pregnant mice were detected by Western blotting. (2) Cell experiments. AML12 cells were treated with CdCl₂ (10 μmol·L⁻¹) for 0, 2, 6, 12, and 24 h. The expressions of oxidative phosphorylation-related proteins, DRP1, and hypoxia inducible factor-1α (HIF-1α) proteins were detected. AML12 cells were pretreated with DRP1 inhibitor Mdivi-1 for 1 h and then CdCl₂ (10 μmol·L⁻¹) for 12 h to detect the expression of oxidative phosphorylation-related proteins and DRP1 protein. AML12 cells were treated with Hif-1α siRNA for 48 h and CdCl₂ (10 μmol·L⁻¹) for 6 h to detect the expression of HIF-1α and DRP1 proteins. Results The results of animal experiments showed that cadmium exposure in pregnant mice had no effects on maternal liver weight and liver coefficient. However, the histomorphological changes and necrosis in hepatocytes were observed. Compared with the control group, the serum ALT and AST levels of pregnant mice in the LCd group were significantly increased after 6 h (P＜0.05), and the levels in the HCd group were significantly increased after 6 and 24 h (P＜0.05). Cadmium exposure during pregnancy significantly up-regulated HIF-1α and DRP1 expressions and down-regulated the expressions of oxidative phosphorylation-related proteins in maternal livers. In vitro cell experiments showed that the expressions of oxidative phosphorylation-related proteins was significantly decreased and HIF-1α and DRP1 protein expressions were significantly increased in the AML12 cells treated with CdCl₂ for 6 h. Mdivi-1 pretreatment significantly antagonized the inhibitory effect of cadmium on the expressions of oxidative phosphorylation-related proteins in AML12 cells, while Hif-1α siRNA pretreatment significantly antagonized the up-regulative effect of cadmium on DRP1 expression in AML12 cells. Conclusion Cadmium exposure in pregnant mice may up-regulate DRP1 expression by activating HIF-1α signaling, then inhibit oxidative phosphorylation level of hepatic cells, and ultimately lead to maternal liver damage.

AIM: To establish individualized drug therapy strategy for patients with rejection and hyperglycemia after liver transplantation. METHODS: Clinical pharmacist collaborated with the surgeons and participated in the diagnosis and treatment of rejection and hyperglycemia after liver transplantation. Taking together liver function, therapeutic drug monitoring, drug-drug interactions between tacrolimus and wuzhi capsule, individualized drug therapy was adapted to improve the prognosis. RESULTS: The patient recovered well and survived in good health till now. CONCLUSION: It is highly suggested that clinical pharmacists actively involved in treatment of more severe and difficult-to-treat disease and design the individualized dosing regimens. This will largely contribute in reduced adverse drug reaction, improved safety and effectiveness in drug use as well as the quality of life in the "post-transplantation era".

Objective To determine how inter-semispinal plane block(ISPB)affects how well in-dividuals recover after having posterior cervical surgery.Methods Seventy-two patients chosen for elective posterior cervical surgery from January to April 2023,41 males and 31 females,aged 18-64,BMI 18-28 kg/m2,ASA physical status Ⅱ or Ⅲ,were divided into two groups using randomized block design:the ISPB group(group I)and the control group(group C),36 patients in each group.Before anesthesia induc-tion,all patients were positioned at the 5th cervical vertebra plane using ultrasound,and 0.25％ropivacaine 20 ml or the same volume of physiological saline were injected into the fascia plane between the bilateral semispinalis cervicis and semispinalis capitis muscles.Anesthetic induction began 15 minutes after injection.QoR-40 and Pittsburgh sleep quality index(PSQI)were recorded 1 day before surgery,1 day and 2 days after surgery,and pain numerical scores(NRS)were recorded 1,6,12,24,and 48 hours after surgery.The number of effective PCIA compressions,the total number of PCIA compressions,the number of relief analgesia,the dosage of sufentanil,remifentanil intraoperatively and postoperatively,and dosage of pentazo-cine postoperatively were recorded.The occurrence of postoperative nausea and vomiting(PONV),the time of first independent walking and oral feeding after surgery,and puncture related complications,such as he-matoma,infection,and local anesthetic poisoning were recorded.Results Compared with 1 day before sur-gery,the total QoR-40 scores and various dimensional scores in the two groups were significantly decreased,while PSQI were significantly increased 1 day and 2 days after surgery(P＜0.05).Compared with group C,the total QoR-40 scores and various dimensional scores except self-care capacity were significantly in-creased,while PSQI were significantly decreased 1 day and 2 days after surgery(P＜0.05),NRS were significantly decreased 1,6,12,and 24 hours after surgery(P＜0.05),the number of effective PCIA compressions,the total number of PCIA compressions,the number of relief analgesia,the dosage of remifentanil intraoperatively,the dosage of pentazocine postoperatively and the occurrence of PONV were significantly decreased(P＜0.05),the time of first independent walking and oral feeding after surgery were significantly shortened in group Ⅰ(P＜0.05).There were no puncture related complications occurred in the two groups.Conclusion Bilateral ISPB can effectively improve the postoperative sleep of patients undergoing posterior cervical surgery,reduce postoperative pain and the incidence of PONV,and improve the postoperative recovery quality.

Objectives:To summarize the clinical and genetic characteristics of the patients with isolated methylmalonic acidemia and investigate the strategies for the diagnosis, treatment and prevention.Methods:Three hundred and fourteen patients (180 males, 134 females) with isolated methylmalonic acidemia were ascertained from 26 provinces or cities across the mainland of China during January 1998 to March 2020. Genetic analysis was performed by Sanger sequencing, gene panel sequencing, whole exome sequencing, multiplex ligation-dependent probe amplification or quantitative PCR. According to the age of onset, the patients were divided to early-onset group (≤12 months of age) and the late-onset group (>12 months of age). They were treated by cobalamin, L-carnitine and (or) special diet and symptomatic treatment. Statistical analysis was done using Chi-square test.Results:Fifty-eight of 314 (18.5%) patients were detected by Newborn screening using liquid chromatography tandem mass spectrometry. Five cases (1.6%) had a postmortem diagnosis. Two hundred and fifty-one patients (79.9%) were clinically diagnosed with an age of onset ranged from 3 hours after birth to 18 years. One hundred and fifty-nine patients (71.0%) belonged to early-onset groups, 65 patients (29.0%) belonged to the late-onset group. The most common symptoms were metabolic crises, psychomotor retardation, epilepsy, anemia and multiple organ damage. Metabolic acidosis and anemia were more common in early-onset patients than that in late-onset patients (20.8%(33/159) vs. 9.2% (6/65), 34.6% (55/159) vs. 16.9% (11/165), χ 2=4.261, 6.930, P=0.039, 0.008). Genetic tests were performed for 236 patients (75.2%), 96.2%(227/236) had molecular confirmation. One hundred and twenty-seven variants were identified in seven genes (MMUT, MMAA, MMAB, MMADHC, SUCLG1, SUCLA2, and MCEE), of which 49 were novel. The mut type, caused by the deficiency of methylmalonyl-CoA mutase, was the most common ( n=211, 93%) cause of this condition. c.729_730insTT, c.1106G>A and c.914T>C were the three most frequent mutations in MMUT gene. The frequency of c.914T>C in early-onset patients was significantly higher than that in late-onset patients (8.3% (18/216) vs. 1.6% (1/64), χ 2=3.859, P=0.037). Metabolic crisis was more frequent in mut type than the other types (72.6% (114/157) vs. 3/13, χ 2=13.729, P=0.001),developmental delay and hypotonia were less frequent in mut type (38.2% (60/157) vs. 9/13, 25.5% (40/157) vs. 8/13, χ 2=4.789, 7.705, P=0.030, 0.006). Of the 58 patients identified by newborn screening, 44 patients (75.9%) who were treated from asymptomatic phase developed normally whereas 14 patients (24.1%) who received treatment after developing symptoms exhibited varying degrees of psychomotor retardation. Conclusions:The characteristics of phenotypes and genotypes among Chinese patients with isolated methylmalonic acidemia were analyzed. Expanded the mutation spectrum of the associated genes. Because of the complex clinical manifestations and severe early onset of isolated methylmalonic acidemia, Newborn screening is crucial for early diagnosis and improvement of prognosis. MMUT gene is recommended for carrier screening as an effort to move the test earlier as a part of the primary prevention of birth defects.
