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 To monitor the antifungal resistance of clinical isolates of Candida spp.in the East China region.Methods MALDI-TOF MS or molecular methods were used to re-identify the strains collected from January 2018 to December 2022.Antifungal susceptibility testing was performed using the broth microdilution method.The susceptibility test results were interpreted according to the breakpoints of 2022 Clinical and Laboratory Standards Institute(CLSI)documents M27 M44s-Ed3 and M57s-Ed4.Results A total of 3 026 strains of Candida were collected,65.33％of which were isolated from sterile body sites,mainly from blood(38.86％)and pleural effusion/ascites(10.21％).The predominant species of Candida were Candida albicans(44.51％),followed by Candida parapsilosis complex(19.46％),Candida tropicalis(13.98％),Candida glabrata(10.34％),and other Candida species(0.79％).Candida albicans showed overall high susceptibility rates to the 10 antifungal drugs tested(the lowest rate being 93.62％).Only 2.97％of the strains showed dose-dependent susceptibility(SDD)to fluconazole.Candida parapsilosis complex had a SDD rate of 2.61％and a resistance rate of 9.42％to fluconazole,and susceptibility rates above 90％to other drugs.Candida glabrata had a SDD rate of 92.01％and a resistance rate of 7.99％to fluconazole,resistance rates of 32.27％and 48.24％to posaconazole and voriconazole non-wild-type strains(NWT),respectively,and susceptibility rates above 90％to other drugs.Candida tropicalis had resistance rates of 29.55％and 26.24％to fluconazole and voriconazole,respectively,resistance rates of 76.60％and 21.99％to posaconazole and echinocandins non-wild-type strains(NWT),and a resistance rate of 2.36％to echinocandins.Conclusions The prevalence and species distribution of Candida spp.in the East China region are consistent with previous domestic and international reports.Candida glabrata exhibits certain degree of resistance to fluconazole,while Candida tropicalis demonstrates higher resistance to triazole drugs.Additionally,echinocandins resistance has emerged in Candida albicans,Candida glabrata,Candida tropicalis,and Candida parapsilosis.

Objective:To investigate the effects of breast milk to total milk intake ratio during hospitalization on the duration of antibiotic therapy in preterm infants less than 34 weeks of gestation.Methods:Clinical data of preterm infants ( n=1 792) less than 34 gestational weeks were retrospectively collected in 16 hospitals of Jiangsu Province Neonatal-Perinatal Cooperation Network from January 1, 2019, to December 31, 2021. The days of therapy (DOT) were used to evaluate the duration of antibiotic administration. The median DOT was 15.0 d (7.0-27.0 d). The patients were divided into four groups based on the quartiles of DOT: Q 1 (DOT≤7.0 d), Q 2 (7.0 d27.0 d) groups. According to the breast milk intake ratio (breast milk intake to total milk intake during hospitalization×100%), they were also divided into four groups: very-low-ratio breastfeeding group (breast milk intake ratio≤25%), low-ratio breastfeeding group (25%75%). Univariate analysis ( Chi-square test and Kruskal-Wallis rank-sum test) was used to analyze the factors influencing DOT. Spearman correlation analysis and trend Chi-square test were used to explore the relationship between breast milk intake ratio and DOT. After using multiple imputations to address missing data, two models were constructed after adjusting for different factors, and multinomial logistic regression model was applied to evaluate the effects of the breast milk intake ratio on DOT. Finally, sensitivity analysis was conducted to assess the stability of the models. Results:(1) Of the 1 792 preterm infants, there were 507 (28.3%) in the Q 1 group, 422 (23.5%) in the Q 2 group, 438 (24.4%) in the Q 3 group and 425 (23.7%) in the Q 4 group. (2) The median values of DOT in the very-low-ratio, low-ratio, medium-ratio and high-ratio breastfeeding groups were 20.0 d (11.0-31.0 d), 20.0 d (11.0-32.0 d), 13.0 d (6.0-25.8 d) and 10.0 d (4.0-21.0 d), respectively. Compared with the very-low-ratio and low-ratio breastfeeding groups, the medium-ratio and high-ratio breastfeeding groups had shorter DOT (all P<0.05). (3) After adjusting for factors with P<0.1 (prenatal glucocorticoid exposure, antimicrobial use within 24 h before delivery, gestational age at delivery, birth weight, Apgar score≤7 at 1 min, neonatal respiratory distress syndrome, infectious pneumonia and early-onset neonatal sepsis) between the DOT quartile groups, it showed that medium-ratio and high-ratio breastfeeding were protective factors in contrast to very-low-ratio breastfeeding in the Q 2, Q 3 and Q 4 groups as compared with the Q 1 group [Q 2 group: OR=0.50 (95% CI: 0.30-0.85) and OR=0.36 (95% CI: 0.26-0.51); Q 3 group: OR=0.31 (95% CI: 0.18-0.55) and OR=0.20 (95% CI: 0.14-0.29); Q 4 group: OR=0.22 (95% CI: 0.12-0.42) and OR=0.17 (95% CI: 0.12-0.26)]. Conclusion:Breast milk intake accounting for over 50% of total milk intake has a positive impact on reducing DOT in premature infants requiring antibiotics, which suggests that breastfeeding should be actively encouraged.

Brain development requires a delicate balance between self-renewal and differentiation in neural stem cells (NSC), which rely on the precise regulation of gene expression. Ten-eleven translocation 2 (TET2) modulates gene expression by the hydroxymethylation of 5-methylcytosine in DNA as an important epigenetic factor and participates in the neuronal differentiation. Yet, the regulation of TET2 in the process of neuronal differentiation remains unknown. Here, the protein level of TET2 was reduced by the ubiquitin-proteasome pathway during NSC differentiation, in contrast to mRNA level. We identified that TET2 physically interacts with the core subunits of the glucose-induced degradation-deficient (GID) ubiquitin ligase complex, an evolutionarily conserved ubiquitin ligase complex and is ubiquitinated by itself. The protein levels of GID complex subunits increased reciprocally with TET2 level upon NSC differentiation. The silencing of the core subunits of the GID complex, including WDR26 and ARMC8, attenuated the ubiquitination and degradation of TET2, increased the global 5-hydroxymethylcytosine levels, and promoted the differentiation of the NSC. TET2 level increased in the brain of the Wdr26^+/- mice. Our results illustrated that the GID complex negatively regulates TET2 protein stability, further modulates NSC differentiation, and represents a novel regulatory mechanism involved in brain development.

Hip fracture is considered as the most severe osteoporotic fracture characterized by high disability and mortality in the elderly. Improved surgical techniques and multidisciplinary team play an active role in alleviating prognosis, which places higher demands on perioperative nursing. Dysfunction, complications, and secondary impact of anaesthesia and surgery add more difficulties to clinical nursing. Besides, there still lack clinical practices in perioperative nursing for elderly patients with hip fracture in China. In this context, led by the Orthopedic Nursing Committee of Chinese Nursing Association, the Expert consensus on clinical practice in perioperative nursing for elderly patients with hip fracture ( version 2023) is developed based on the evidence-based medicine. This consensus provides 11 recommendations on elderly patients with hip fracture from aspects of perioperative health education, condition monitoring and inspection, complication risk assessment and prevention, and rehabilitation, in order to provide guiding advices for clinical practice, improve the quality of nursing and ameliorate the prognosis of elderly patients with hip fracture.

Objectives:To explore the association between different blood pressure levels at baseline and early-onset heart disease among young adults under 40 years in China. Methods:This prospective cohort study included 35 993 subjects who participated in the physical examination of the employees of Kailuan Group for the first time from 2006 to 2012 and were younger than 40 years,with complete blood pressure data and had no history of heart disease.Participants were followed up to the end of 2021.The primary endpoint was early-onset heart disease(including coronary heart disease,atrial fibrillation,and heart failure).According to 2018 Chinese guidelines for the management of hypertension,the participants were divided into four groups:normal blood pressure group(n=13 208),elevated blood pressure group(n=16 576),stage 1 hypertension group(n=4 357),and stage 2-3 hypertension group(n=1 852).The cumulative incidence of heart disease among participants with different blood pressure levels at baseline was compared using log-rank test.Multivariate Cox proportional hazard regression model was used to analyze the impact of different blood pressure levels at baseline on early-onset heart disease in this cohort. Results:After a mean follow-up of(12.5±2.6)years,the cumulative incidence of early-onset heart disease in normal blood pressure group,elevated blood pressure group,stage 1 hypertension group,stage 2-3 hypertension group were 0.47%,0.97%,3.56%and 4.42%respectively(log-rank P<0.01).After adjusting for confounding factors such as age and sex,Cox regression analysis showed that the HR(95%CI)of heart disease in the elevated blood pressure group,hypertension grade 1 group and hypertension grade 2-3 group were 1.59(1.12-2.24),2.08(1.41-3.08)and 3.20(2.11-4.85)(all P<0.01),respectively,compared with the normal blood pressure group. Conclusions:Elevated blood pressure is a risk factor for early-onset heart disease among young Chinese population.

Objective: To understand changes and health equity of low vision in children and adolescents in Chongqing, and to provide reference for student myopia prevention and control. Methods: Using longitudinal studies, all school students in grades 1 to grade 12 in Chongqing were examined for visual acuity during 2018 to 2021, and the prevalence as well as changes of low vision were analyzed. In 2021, stratified random sampling was used to evaluate the health equity of uncorrected visual acuity and diopter(spherical equivalent, SE). Results: The prevalence of low vision for children and adolescents in Chongqing from 2018 to 2021 was 54.12%, 58.17%, 60.03% and 58.20% respectively. Low vision showed an increasing trend in the first three years and decreased by 1.83% in 2021 as compared with 2020( χ 2 trend =13 870.45, P <0.01). The difference in the detection rate of poor vision among students in different grades was statistically significant( χ 2=17 396.36, 2 093.95, 771.87, P <0.01). From 2018 to 2021, the detection rate of low vision in girls was higher than that of boys( P <0.01). The Gini coefficient was 0.054 57 for uncorrected visual acuity in urban area, higher than in rural areas (0.035 94). Meanwhile, the Gini coefficient of urban and rural SE was 0.065 82, higher than the country (0.049 30). The results showed that myopia in children and adolescents was more uneven in urban areas. Conclusion The adjustment of myopia prevention and control strategies in the late stage of the novel coronavirus pneumonia epidemic is related to the reduction of the detection rate of poor vision in children and adolescents in Chongqing. Low vision varied by grade and gender, suggesting tailored myopia prevention and control strategy. The detection rate of poor vision in cities is more uneven than in rural areas, and different myopia prevention and control measures need to be implemented according to regional characteristics.

Objective: To investigate the current status of myopia in children and adolescents in Qamdo, Tibet, and analyze related influencing factors, so as to provide a basis for the prevention and control of adolescents in plateau areas. Methods: A cross sectional study was conducted among 959 children and adolescents randomly selected from one district and two counties in Qamdo (from the fourth grade of elementary school to the second grade of high school) for visual acuity and refraction tests and filled out a vision related behavior questionnaire to analyze the incidence of myopia among adolescents in the region and its associated factors. Results: The myopia rate of adolescents in grades 4-11 was 54.43%, the rate of undercorrection of refractive errors was 85.25%, and the percentage of students wearing eyeglasses was 34.67%,fully vision correction rate was 42.54%. The myopia rate of students in grades 4-6 was 35.14%, 64.71% in grades 7-9, and 73.48% in grades 10-11. The myopia rate increased with grades( χ 2= 101.18 , P <0.01). The myopia rate (70.40%) of urban students (grades 4-9) was higher than that of county level(41.45%), and the myopia rate of students with myopia from either parent (68.24%) was higher than that of students without myopia (51.91%) , the myopia rate of girls (59.96%) was higher than that of boys (48.36%)( χ 2=53.19，13.46，12.98， P <0.01). Use electronic products for more than 2.5 hours per day, electronic devices usage after bedtime, the light low indoor brightness when studying on a sunny day, and only use one of the table lamps or roof lights when studying at night, preference for fried food, poor sleep quality, in the morning the students who still feel tired are at higher risk of myopia( χ 2=10.35, 10.91, 6.87, 4.25, 4.97, 5.71, 12.11, P < 0.05). Multivariate regression analysis showed that the occurrence of myopia was related to region, grade, gender, parental myopia, time spent on electronic products every day in the past 5 months, and sleep quality( P <0.05). Conclusion The high rate of myopia in children and adolescents in Qamdo may be related to the quality of sleep, the length of time electronic products are used, the eye environment, and the frequency of eating fried foods. Outdoor activities do not show significant differences.

Objective:To analysis the expression of CD7 in NK/T-cell lymphoma as well as study the correlations between CD7 and clinical survival and prognosis.Methods:The clinical and pathological indicators of 112 NKTCL patients who were admitted to or consulted at the First Affiliated Hospital of Zhengzhou University between May 2008 and December 2019 were analyzed retrospectively. The CD7 expression in the tumor tissues was detected using immunohistochemistry staining, and the influence of CD7 expression on the survival and prognosis in the patients was analyzed.Results:The CD7 expression rate was 84.82% in 112 NKTCL patients, and its expression was not influenced by sex, age, and the primary site. An analysis of the complete clinical data of 72 patients showed that the CD7 expression was significantly correlated with the PINK score, tumor metastasis, and peripheral blood EBV-DNA level. However, the Ann Arbor stage, bone marrow involvement, B symptoms, IPI/aaIPI score, Ki-67, EBER, TIA-1, Granzyme B, LDH, and β 2-MG were not associated with the CD7 expression. The 1-year, 3-year, and 5-year overall survival (OS) rates of the 72 patients were 81.2%, 61.8%, and 58.8%, respectively, and the progression-free survival (PFS) rates were 53.5%, 29.4%, and 24.0%, respectively. The median overall survival (median-OS, mOS) was 81 mon, and the median progression-free survival (median-PFS, mPFS) was 14 mon. The 3-year OS rates in the CD7-positive group and the CD7-negative group were 58.1% and 83.9%, respectively, ( P>0.05) . The 3-year PFS rates were 21.7% and 51.9%, respectively ( P<0.05) . The univariate analysis showed that age, primary tumor site, Ann Arbor stage, IPI/aaIPI score, PINK score, LDH, β 2-microglobulin, EBV-DNA, Ki-67, and CD7 influenced patient prognosis. The multivariate analysis showed that Ann Arbor stage and CD7 were independent prognostic factors for PFS, while PINK score and Ki-67 were independent prognostic factors for OS. Conclusions:The expression rate of CD7 in NKTCL was high and was closely related to poor patient prognosis. The patients with high levels of EBV-DNA, metastatic disease, or high PINK score were more likely to express CD7.
