Objective:To systematically assess the effectiveness and safety of acupuncture for spastic hemiplegia after ischemic stroke. Methods:Randomized controlled trials(RCTs)of acupuncture treatment for spastic hemiplegia after ischemic stroke meeting the inclusion criteria in Cochrane Library,Medline,Excerpta Medica Database(EMBASE),PubMed,China National Knowledge Infrastructure(CNKI),SinoMed,Chongqing VIP Database(VIP),and Wanfang Data Knowledge Service Platform(Wanfang)published from each database's inception to February 2023 were retrieved by computer.Two reviewers independently extracted data and evaluated the risk of bias using Cochrane's risk of bias tool.Review Manager 5.4 was used for data analysis.Continuous data were evaluated using mean difference(MD)with a 95%confidence interval(CI),and dichotomous data were analyzed using risk ratio(RR). Results:A total of 24 trials,including 1 970 participants,were included in the study.The meta-analysis of 7 trials showed that compared to the rehabilitation therapy,acupuncture therapy was more effective in improving the simplified Fugl-Meyer assessment score after 1-month treatments[MD=10.52,95%CI(7.81,13.23),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.18,95%CI(11.34,27.02),P<0.001],and the 6-month treatment course resulted in better outcomes than the 1-month course.The meta-analysis of 8 trials showed that acupuncture had a better improvement on the Barthel index score than rehabilitation therapy after 1-month treatments[MD=10.78,95%CI(8.91,12.64),P<0.001].The meta-analysis of 2 articles showed the same tendency after 6-month treatments[MD=19.94,95%CI(19.02,20.87),P<0.001],and the 6-month course was better than the 1-month course.The meta-analysis of 2 trials showed that the effective rate of the modified Ashworth scale score improvement was more notable in the acupuncture group after 1-month treatments[RR=1.20,95%CI(1.02,1.40),P=0.020].One trial reported no adverse event,and 1 trial reported 3 adverse events without severe influence. Conclusion:Acupuncture might be an effective and safe therapy for spastic hemiplegia after ischemic stroke,but more high-quality,large-sample objectively-evaluated RCTs are needed to validate the conclusion.

This study was purposed to investigate the expression of RPL36A (ribosomal protein 36a) in the newly diagnosed acute myeloid leukemia (AML) cells and its mechanism at the molecular level. The RPL36A mRNA expression in the newly diagnosed AML cells, U937 cells and normal MNCs was determined by RT-PCR. Small interfering RNA (siRNA) targeting to RPL36A was transfected into U937 cells by Lipofectamine 2000 system. Proliferation, cell cycle, apoptosis of U937 were observed through MTT assay, flow cytometry, acridine orange/ethidium bromide (AO/EB) double staining, TUNEL and Annexin V/FITC respectively. RPL36A mRNA and protein expression levels were detected by reverse transcriptase-polymerase chain reaction (RT-PCR) and Western blot analysis respectively. The results showed that RPL36A expression in the newly diagnosed AML cells and U937 cells was significantly upregulated. The average OD value of U937 cells transfected with RPL36A siRNA was significantly lower as compared with 3 control groups. The cell percentage in G2-and S-phase increased, which indicated the inhibition effect of RPL36A siRNA on cell proliferation. Remarkable cell apoptosis in U937 cells treated with RPL36A siRNA was observed by AO/EB, TUNEL analysis and Annexin V/FITC assay; RPL36A mRNA and protein expression level of U937 cells treated with siRNA were significantly declined in a time-dependent manner (r=0.9813 and 0.9537). It is concluded that the RPL36A expression in the AML cells is significantly enhanced and the RPL36A gene may be involved in regulation of cell cycle and cell apoptosis of AML, which promotes proliferation of AML cells and inhibits apoptosis of cells.

Objective To evaluate and compare the short-term effects of two kinds of plastic mulch on Oncomelania hupensis snail control in irrigation and drainage ditches with snails in Yunnan Province. Methods The irrigation and drainage ditches with high density of Oncomelania hupensis snails were chosen as the investigation sites,and then 4 groups were set,namely a colorless plastic mulch group,black plastic mulch group,colorless plastic mulch with molluscicide group and black plastic mulch with molluscicide group. The snail situation of the 4 groups was surveyed before the experiment and 7,14,21,30 days after covering plastic mulch,and the snail death rates were compared among the 4 groups. Meanwhile,the hourly temperatures of soil surface,soil surface under plastic mulch and soil layer 5,15 cm under the surface as well as the weather situation during the study period were measured and recorded. Results The average snail mortality rate of the colorless plastic mulch group was only 15.29% that was higher than that of the black plastic mulch group(6.56%)(P < 0.01). The average snail mortality rates of the colorless and black plastic mulch with molluscicide groups were 40.80% and 50.15%,respectively,and there was no statis-tic difference between them(P > 0.05). Both kinds of plastic mulches could raise the temperature of the soil surface under plas-tic mulch and the soil layer below it,and the temperature of soil under the mulches increased over the cover time,and the aver-age temperature of the soil surface under the black mulch in 30 days was higher than that under the colorless mulch. Conclu-sion It is not suitable to use plastic mulch only in irrigation and drainage ditches with snails widely in Yunnan Province be-cause of its low effect,and if necessary,the molluscicide should be added.

Objective To analyze the virulence genes and drug resistance in Vibrio parahaemolyti-cus strains isolated in Nantong City from 2015 to 2016 in order to provide reference for the prevention and treatment of Vibrio parahaemolyticus infection and for rational use of medicines. Methods Virulence genes of tlh,tdh and trh in Vibrio parahaemolyticus strains were detected by fluorescence quantitative PCR. Micro-broth dilution method was used to analyze antimicrobial resistance in these strains to 15 kinds of antibiotics. Results Eighty-two Vibrio parahaemolyticus strains were all positive for tlh gene and negative for trh gene and among them,72 carried tdh gene (87.8%). Antimicrobial resistance rates of these strains to ampicil-lin,cefazolin,tetracycline and chloramphenicol were all 1.2% (1/82). Two strains (2.4%) were resist-ant to trimethoprim/sulfamethoxazole. All strains were sensitive or intermediate to another 10 kinds of antibi-otics. Conclusion From 2015 to 2016,Vibrio parahaemolyticus strains carrying virulence genes of tlh and tdh were prevalent in Nantong and no trh gene-positive strains were reported. Except ampicillin, cefazolin, tetracycline,chloramphenicol and trimethoprim/sulfamethoxazole these five kinds of antibiotics, the remai-ning 10 kinds of antibiotics were effective against Vibrio parahaemolyticus and could be used as the treatment of choice.

Objective: To measure the body mass index (BMI) of secondary school students and analyze its association with the physical fitness index, so as to improve the physical health of middle school students. Methods: Using a randomized cluster stratified sampling method, 3 813 secondary school students from six cities (Ganzhou, Ji an, Fuzhou, Nanchang, Shangrao and Jiujiang) in Jiangxi Province, China, were selected in September 2022. Questionnaire survey was administered to obtain basic information and to assess the nutritional status and physical fitness tests were conducted among secondary school students. The study was stratified by gender and age, and the Kruskal Wallis H test was used to compare the differences in the mean values of grip strength, sit-ups, standing long jump performance and strength quality among secondary school students with different BMI levels, while the correlation between BMI and strength quality index was inferred by using curve regression analysis. Results: There was statistical significance in the strength quality index of middle school students with different BMI level ( H=56.79, 8.84, P <0.05). Except 13 years old group, the difference of physical fitness by BMI grade strength quality index of boys in other age groups was statistically significant ( H =22.21, 16.23, 17.98, 18.21, 8.08), while the difference of physical fitness by BMI of girls at 14 years old was statistically significant ( H =9.11)( P <0.05). The curve fitting using regression showed that the physical fitness index and BMI of middle school students (boys and girls) show an inverted U-shaped curve. The physical fitness index was higher in the middle region of BMI ( Z-score) and lower in the two end regions, while showing a decreasing trend from the middle to the two ends. Conclusion An association is found between BMI and physical fitness among secondary school students in Jiangxi Province, and wasting and overweight/obesity are negatively correlated with physical fitness. Greater attention should be paid to the nutritional status of secondary school students to ensure the normal development of physical fitness.

OBJECTIVETo study the status of loss of heterozygosity (LOH) of chromosome 1p/19q and p53 protein expression in oligodendroglioma, as compared to astrocytoma.

METHODSOne hundred and ninety-one cases of glioma of different histologic types and grades, including 116 cases of low-grade of oligodendroglioma (86 paraffin-embedded and 30 fresh tissues), 45 cases of anaplastic oligodendroglioma (all paraffin-embedded tissues) and 30 cases of astrocytoma of various grades (all paraffin-embedded tissues), were enrolled into the study. The LOH of chromosome 1p/19q was investigated by polymerase chain reaction (PCR)-based microsatellite analysis. The p53 protein expression was demonstrated by immunohistochemical staining.

RESULTSThe rates of 1p loss, 19q loss and 1p/19q loss were 69.8%, 64%, and 57.0% respectively in the 86 paraffin-embedded low-grade oligodendroglioma samples, as compared to 71.1%, 60.0% and 55.6% respectively in the 45 paraffin-embedded anaplastic oligodendroglioma samples. There was no difference of LOH of 1p/19q between low-grade oligodendroglioma and anaplastic oligodendroglioma (P>0.05). In the 30 cases of low-grade oligodendroglioma with fresh tissues available, the rates of 1p loss, 19q loss and 1p/19q loss were 70.0%, 63.3% and 60.0% respectively. The LOH of 1p/19q between paraffin-embedded and fresh samples was not statistically significant (P>0.05). In the 30 cases of astrocytoma, the rates of 1p loss, 19q loss and 1p/19q loss were 23.3%, 33.3% and 20.0% respectively, which were significantly less than those in oligodendroglioma (P<0.05). The expression of p53 protein was significantly lower in low-grade oligodendroglioma (8.1%) than in anaplastic oligodendroglioma (31.1%, P=0.007). The expression of p53 protein in oligodendroglioma was also lower than in astrocytoma (P=0.001). Furthermore, p53 protein expression negatively correlated with 1p/19q loss in anaplastic oligodendroglioma (P<0.05).

CONCLUSIONSBoth paraffin-embedded and fresh tissues are suitable for analysis of LOH of chromosome 1p/19q. Oligodendroglioma demonstrates a higher frequency of LOH of chromosome 1p/19q and lower expression of p53 protein than astrocytoma. The LOH of chromosome 1p/19q negatively correlates with the expression of p53 protein. These parameters have both diagnostic and prognostic values.

OBJECTIVE: To study the clinical features of vasovagal syncope (VVS) and postural orthostatic tachycardia syndrome (POTS) in children with neurological symptoms at disease onset. METHODS: A retrospective analysis was performed on the medical data of 88 children with the initial symptoms of the nervous system, such as transient loss of consciousness, dizziness, headache, and convulsion, who were finally diagnosed with VVS or POTS. RESULTS: Of the 88 children, there were 35 boys (40%) and 53 girls (60%), with an age of 4-15 years. The peak age of onset was between 10 and 13 years. All the children had the initial symptoms of transient loss of consciousness, dizziness, headache, and convulsion. Nervous system diseases were excluded by electroencephalography, cerebrospinal fluid examination, and cranial MRI. Of the 88 children, 53 (60%) were confirmed with VVS, and 35 (40%) with POTS, according to the results of head-up tilt test (HUTT). Five children with the initial symptom of transient loss of consciousness were misdiagnosed with epilepsy. Predisposing factors were determined for 59 children (67%), and prolonged standing was the most common factor, followed by change in body position and strenuous exercise. Premonitory symptoms were observed in 66 children (75%), among which chest discomfort was the most common symptom, followed by gastrointestinal symptoms (nausea, vomiting, and abdominal pain) and pale complexion. All 88 children received health education and exercise for autonomic nerve function, among whom 53 children with VVS were given oral rehydration salts and 35 children with POTS were given oral rehydration salts and metoprolol. All 88 children were followed up for 18 months, and the response rates to the above treatment at 3, 6, 12, and 18 months of follow-up were 87%, 93%, 93%, and 90% respectively. CONCLUSIONS In addition to nervous system diseases, functional cardiovascular diseases including VVS and POTS should be considered for children with the initial symptoms of transient loss of consciousness, dizziness, headache, and convulsion. HUTT can be used to make a confirmed diagnosis, and the early treatment can achieve a good outcome.
