OBJECTIVE: To explore the effect of acupuncture therapy on dysphagia in patients with Parkinson's disease. METHODS: This randomized controlled study lasted 42 days and included 112 patients with Parkinson's disease and dysphagia. Participants were randomly assigned to the experimental and control groups (56 cases each group) using the completely randomized design, all under routine treatment. The experimental group was given acupuncture therapy. The primary outcome was Penetration-Aspiration Scale (PAS). The secondary outcomes were (1) Standardized Swallowing Assessment (SSA), and (2) nutritional status including body mass index (BMI), serum albumin, prealbumin, and hemoglobin. Adverse events were recorded as safety indicators. RESULTS: One participant quitted the study midway. There were no significant differences in baseline assessment (P>0.05). After treatment, both groups showed significant improvement in PAS, SSA and nutritional status except for BMI of the control group. There were significant differences between the two groups in the PAS for both paste and liquid, SSA (25.18±8.25 vs. 20.84±6.92), BMI (19.97±3.34 kg/m²vs. 21.26 ±2.38 kg/m²), serum albumin (35.16 ±5.29 g/L vs. 37.24 ±3.98 g/L), prealbumin (248.33 ±27.72 mg/L vs. 261.39 ±22.10 mg/L), hemoglobin (119.09±12.53 g/L vs. 126.67±13.97 g/L) (P<0.05). There were no severe adverse events during the study. CONCLUSION: The combination of routine treatment and acupuncture therapy can better improve dysphagia and nutritional status in patients with Parkinson's disease, than routine treatment solely.

Oligodendrocyte lineage cells, including oligodendrocyte precursor cells (OPCs) and oligodendrocytes (OLs), are essential in establishing and maintaining brain circuits. Autophagy is a conserved process that keeps the quality of organelles and proteostasis. The role of autophagy in oligodendrocyte lineage cells remains unclear. The present study shows that autophagy is required to maintain the number of OPCs/OLs and myelin integrity during brain aging. Inactivation of autophagy in oligodendrocyte lineage cells increases the number of OPCs/OLs in the developing brain while exaggerating the loss of OPCs/OLs with brain aging. Inactivation of autophagy in oligodendrocyte lineage cells impairs the turnover of myelin basic protein (MBP). It causes MBP to accumulate in the cytoplasm as multimeric aggregates and fails to be incorporated into integral myelin, which is associated with attenuated endocytic recycling. Inactivation of autophagy in oligodendrocyte lineage cells impairs myelin integrity and causes demyelination. Thus, this study shows autophagy is required to maintain myelin quality during aging by controlling the turnover of myelin components.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

Objective To explore the value of MR diffusion tensor imaging(DTI)in evaluating the effect of march training on the thigh muscles of recruits.Methods DTI scans of the right thigh were performed three times in forty recruits:before and after the march training and one month after the rest.Fractional anisotropy(FA)was measured on the cross-sectional images of the thigh muscles,including rectus femoris(RF),vastus medialis(VM),vastus lateralis(VL),vastus intermedius(VI),gracilis muscle(GM),sartorius muscle(SM),semitendinosus muscle(STM),semimembranosus muscle(SMM),long head of biceps femoris(LHBF)and short head of biceps femoris(SHBF).The percentage changes in FA values of each muscle after the training and rest were calculated.Paired samplet-tests were used to analyze the differences in FA among the thigh muscles at different time points,and one-way ANOVA was used to analyze the differences in the percentage changes of FA among the thigh muscles after the training and rest.Results Compared to pre-training,the FA values of all thigh muscles significantly decreased after the training,with statistical differences(P＜0.05).After the rest,the FA values of all thigh muscles recovered,but statistical differences remained in RF(P＜0.001),VM(P＜0.001),VL(P=0.001),STM(P=0.046),and LHBF(P=0.013).After the training and rest,the FA values of the recruits'thigh muscles showed a"decreasing first and then increasing"trend.There were statistical differences in the percentage changes of FA after the training and the recovery percentages of FA after the rest among the thigh muscles(P＜0.001,P＜0.001).Conclusion DTI may reflect the ultra-structure changes in the thigh muscles of recruits after the march training and provide a quantitative and noninvasive assessment of muscle micro-injuries.

Objective To investigate the effect of intraoperative renal artery resistance index(RI)in predicting postoperative acute kidney injury(AKI)in patients undergoing cardiac surgery with cardiopul-monary bypass(CPB).Methods Forty-four patients undergoing elective cardiac surgery with CPB,21 males and 23 females,aged ≥18 years,BMI 18.5-30.0 kg/m2,ASA physical status Ⅰ-Ⅲ,were select-ed.Left renal artery peak systolic velocity(PSV)and end-diastolic velocity(EDV)were measured by transesophageal echocardiography(TEE)20 minutes after general anesthesia induction(T1)and 30 minutes after CPB cessation(T2).RI was calculated as(PSV-EDV)/PSV.Patients were divided into two groups:the AKI group and the non-AKI group,according to whether occurred AKI by the diagnostic criteria of the kidney disease:improving global outcomes organization(KDIGO).Logistic multivariate regression analysis was performed to identify the risk factors for AKI occurrence.Results Sixteen patients(36％)oc-curred AKI.Compared with the non-AKI group,the CPB duration and aortic cross-clamp duration were sig-nificantly prolonged(P＜0.05),the renal artery RI at T,and T2 were significantly increased in the AKI group(P＜0.05).Multivariate logstic analysis showed that RI at T2 was an independent risk factor for AKI occurrence after cardiac surgery,the AUC was 0.893(95％CI 0.794-0.991,P＜0.010),the sensitivity and specificity were 84.5％and 78.6％,respectively,and the cut-off value was 0.720.Conclusion Intra-operative renal artery RI in patients undergoing cardiac surgery is an independent risk factor for AKI after cardiac surgery,and renal artery RI＞0.720 at 30 minutes after CPB cessation can serve as a predictive in-dicator for AKI after cardiac surgery.

Objective:To investigate the influence of curative-intent resection with textbook outcomes of liver surgery (TOLS) on long-term prognosis of gallbladder carcinoma (GBC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 824 patients with GBC in the national multicenter database of Biliary Surgery Group of Elite Group of Chinese Journal of Digestive Surgery, who were admitted to 15 medical centers from January 2014 to January 2021, were collected. There were 285 males and 539 females, aged (62±11)years. According to the evalua-tion criteria of TOLS, patients were divided into those who achieved TOLS and those who did not achieve TOLS. Measurement data with normal distribution were represented as Mean± SD, and com-parison between groups was conducted using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. Comparison of ordinal data were conduc-ted using the Mann-Whitney U test. The Kaplan-Meier method was used to calculate survival rate and draw survival curve, and the Log-rank test was used for survival analysis. The COX stepwise regression model with backward Wald method was used for univariate and multivariate analyses. Results:(1) Achievement of TOLS. Of the 824 patients undergoing curative-intent resection for GBC, there were 510 cases achieving TOLS and 314 cases not achieving TOLS. (2) Follow-up. Of the 824 patients undergoing curative-intent resection for GBC, after excluding 112 deaths within 90 days after discharge, 712 cases were included for the survival analysis. The median follow-up time, median overall survival time and 5-year overall survival rate of the 510 patients achieving TOLS were 22.1(11.4,30.1)months, 47.6(30.6,64.6)months and 47.5%. The median follow-up time, median overall survival time and 5-year overall survival rate of the 202 patients not achieving TOLS were 14.0(6.8,25.5)months, 24.3(20.0,28.6)months and 21.0%. There was a significant difference in overall survival between patients achieving TOLS and patients not achieving TOLS ( χ2=58.491, P<0.05). (3) Analysis of factors influencing prognosis of patients. Results of multivariate analysis showed that TOLS, carcinoembryonic antigen (CEA), CA19-9, poorly differentiation of tumor, T2 stage of eighth edition of American Joint Committee on Cancer (AJCC) staging, T3 and T4 stage of eighth edition of AJCC staging, N1 stage of the eighth edition of AJCC staging, N2 stage of the eighth edition of AJCC staging, adjuvant therapy were independent factors influencing overall survival time of patients undergoing curative-intent resection for GBC ( hazard ratio=0.452, 1.479, 1.373, 1.612, 1.455, 1.481, 1.835, 1.978, 0.538, 95% c onfidence interval as 0.352-0.581, 1.141-1.964, 1.052-1.791, 1.259-2.063, 1.102-1.920, 1.022-2.147, 1.380-2.441, 1.342-2.915, 0.382-0.758, P<0.05). Conclusion:Patients under-going curative-intent resection for GBC with TOLS can achieve better long-term prognosis.

The emerging and re-emerging arthropod-borne infectious diseases pose a serious threat to global public health security. Field and laboratory studies of arthropods of medical importance are essential and critical for the prevention and control of arthropod-borne infectious diseases. Various institutions or universities in China have been conducting research in the field or laboratory study of arthropods of medical importance, but up to 2023, it is still lacking detailed biosafety guidelines or recommendations that can guide the related work for arthropods of medical importance. In order to proactively address potential biosafety issues in the field or laboratory activities related to arthropods of medical importance, improve the standardization of arthropod biosafety classification, operations, and protection, and ensure the safety of practitioners, an expert consensus on the biosafety recommendation of arthropods of medical importance in field and laboratory has been developed, aiming to guide the future work of arthropods and ensure the national biosafety and biosecurity of China.

Objective To compare the application effect of intermittent androgen deprivation(IAD)and continued androgen deprivation(CAD)on advanced prostate cancer and influence on prognosis.Methods The patients with advanced prostate cancer were divided into treatment group(86 cases)and control group(62 cases)according to the cohort method.The treatment group was given IAD regimen(subcutaneous injection of 3.6 mg goserelin once every 28 days)combined with oral administration of flutamide(250 mg every 3 times a day)or combined with oral administration of bicalutamide(50 mg once a day),and the control group was treated with CAD regimen(bilateral orchiectomy combined with continuous flutamide or bicalutamide orally,with the same dosage as the treatment group).The observation follow-up time of both groups was ≥9 months.Efficacy,serum total testosterone(TT),prostate specific antigen(PSA)and vascular endothelial growth factor(VEGF)were compared between the two groups after treatment,and the side effects of treatment,quality of life[Functional Assessment of Cancer Therapy-Prostate(FACT-P)]and disease progression were evaluated.Results At 9 months after treatment,the objective response rates(ORR)in treatment group and control group were 30.99％(22 cases/71 cases)and 29.09％(16 cases/55 cases),and the disease control rates(DCR)were 71.83％(51 cases/71 cases)and 69.09％(38 cases/55 cases)respectively(P＞0.05).Serum TT levels in treatment group and control group were(25.53±9.44)and(22.51±8.28)ng·dL-1,PSA levels were(4.48±1.02)and(4.32±0.95)ng·mL-1,and VEGF levels were(121.03±35.26)and(118.65±33.42)pg·mL-1 respectively(all P＞0.05).The incidence rates of hot flash in treatment group and control group were 21.13％and 56.36％,the incidence rates of breast swelling pain were 16.90％and 34.55％,and the incidence rates of osteoporosis were 8.45％and 25.45％respectively(all P＜0.05).The scores of physical condition of FACT-P in treatment group and control group were(24.15±4.22)and(20.28±3.71)points,the scores of life condition were(20.28±2.94)and(17.81±2.84)points,scores of prostate cancer specific(PCS)module were(33.21±6.32)and(28.42±5.43)points,respectively,the difference were all statistically significant(all P＜0.05).The cumulative progression-free survival rates in treatment group and control group were 61.97％and 58.18％(P＞0.05).Conclusion IAD is as effective as CAD in the treatment of advanced prostate cancer and has a similar effect on the prognosis of patients,but the former one has fewer side effects of treatment and helps to improve the quality of life of patients.
