BACKGROUND:Stroboscopic visual training can force sensory reweighting to restore the original weights by increasing sensitivity to proprioceptive information,which may be an effective method to improve proprioception. OBJECTIVE:To determine the effects of balance training in three conditions,low frequency,high frequency and normal vision,on ankle proprioception in patients with chronic ankle instability. METHODS:Thirty-six patients with chronic ankle instability recruited from the students of Southwest Medical University were randomly assigned to a low-frequency vision training group,a high-frequency vision training group,and a normal vision training group,with 12 subjects in each group.Subjects in the three groups underwent progressive hop stabilization and balance training,in which the low-frequency vision training group and the high-frequency vision training group wore stroboscopic spectacles during the training,with a stroboscopic frequency of 1.75 and 5 Hz,respectively.The training in each group was performed three times a week for 4 consecutive weeks.Assessments,including ankle proprioception,ankle stability self-assessment and dynamic postural stability,were performed before training and within 1 week after the completion of training. RESULTS AND CONCLUSION:There was a significant main effect of time factor in ankle proprioception(P<0.05).Compared with the pre-training period,subjects in the low-frequency vision training group and the high-frequency vision training group showed significant improvement in ankle proprioception after 4 weeks of training(P<0.05);and subjects in the low-frequency vision training group showed a significant improvement in ankle proprioception compared with that of the normal vision training group after 4 weeks of training(P<0.05).There were significant main effects of time factor and group×time interaction in ankle proprioception(P<0.05).Compared with the pre-training period,the ankle stability self-assessment in all three groups was improved after 4 weeks of training(P<0.05).And the ankle stability self-assessment in high-frequency visual training group was higher than that in normal vision training group after 4 weeks of training(P<0.05).Compared with the pre-training period,subjects in the low-frequency vision training group and the high-frequency vision training group showed significant improvements in forward dynamic postural stability,posteromedial dynamic postural stability,and posterolateral dynamic postural stability after 4 weeks of training(P<0.05),while in the normal vision training group,forward dynamic postural stability and posterolateral dynamic postural stability were significantly improved after 4 weeks of training(P≤0.05).To conclude,balance training under stroboscopic visual conditioning improves proprioception,ankle stability self-assessment,and dynamic postural stability in patients with chronic ankle instability regardless of frequency.

This article systematically analyzes the historical evolution of the name， origin， quality evaluation， harvesting， processing and other aspects of Picrorhizae Rhizoma by referring to the medical books， prescription books， and other documents of the past dynasties， combined with relevant modern research materials， in order to provide a basis for the development and utilization of famous classical formulas containing this medicinal herb. The research results indicate that Picrorhizae Rhizoma was first recorded in New Revised Materia Medica from the Tang dynasty. Throughout history， Huhuanglian has been used as its official name， and there are also aliases such as Gehu Luze， Jiahuanglian and Hulian. The main source of past dynasties is the the rhizomes of Picrorhiza kurrooa and P. scrophulariiflora. In ancient times， Picrorhizae Rhizoma was mainly imported by foreign traders via Guangzhou and other regions， and also produced in China， mainly in Xizang. In ancient times， it was harvested and dried in early August of the lunar calendar， while in modern times， it is mostly harvested from July to September， with the best quality being those with thick and crispy rhizomes without impurities， and bitter taste. Throughout history， Picrorhizae Rhizoma was collected， washed， sliced， and dried before being used as a raw material for medicine， it has a bitter and cold taste， mainly used to treat bone steaming， hot flashes， infantile chancre fever， and dysentery. There is no significant difference in taste and efficacy between ancient and modern times. Based on the research results， it is recommended that the rhizomes of P. scrophulariiflora in the 2020 edition of Chinese Pharmacopoeia， or the rhizomes of P. kurrooa， can be used in famous classical formulas containing this medicinal herb， which can be processed according to the processing requirements marked by the original formula. For those without clear processing requirements， the dried raw products are used as medicine.

Objective: To explore effects and maintenance of school based sexual abuse prevention programs for minors, so as to provide scientific evidences for optimizing intervention design and policy making. Methods: Six Chinese and English databases were searched, including CNKI, Wanfang Database, Medline (via PubMed), Embase, Cochrane Library and Web of Science, with the time frame set from database inception to December 31, 2024. Studies on school based sexual abuse prevention programs for minors were selected, and data on knowledge, attitudes and skills related to sexual abuse prevention were extracted. Meta analysis was performed using Stata 17. Results: A total of 26 studies were included. The Meta analysis results showed that school based sexual abuse prevention programs improved participants knowledge ( SMD=1.24, 95%CI =0.96-1.52), attitudes ( SMD=0.62, 95%CI =0.19-1.04) and skills ( SMD=0.66, 95%CI =0.50-0.83) (all P <0.01). During the overall follow up, the maintenance rates for knowledge, attitudes, and skills were 0.97(95% CI =0.95-1.00), 0.99(95% CI =0.95-1.04) and 1.01(95% CI =0.99-1.04), respectively, with no statistically significant differences (all P >0.05). However, knowledge retention declined significantly when follow up exceeded three months ( R=0.91, 95%CI=0.83-0.99, P <0.01), while skills retention ( R=0.94, 95%CI=0.87-1.02, P = 0.23) remained higher than knowledge and attitudes ( R=0.98, 95%CI=0.96-1.00, P =0.13), demonstrating stronger long term effects. Conclusion School based sexual abuse prevention programs are effective in enhancing participants knowledge, attitudes and skills, but the intervention effects diminish over time, particularly in knowledge retention.

Objective:Based on the cost-effectiveness,it aimed to assess the health benefits amd economic value of screening,di-agnosis,treatment,and optimal delicacy management of liver disease in hepatocellular carcinoma(HCC)patients.Methods:A Deci-sion tree-Markov model was developed to compare the cost-effectiveness of HCC screening and long-term surveillance versus no screening in population at risk from the health care system perspective.Results:It is found that HCC screening was a cost-effective approach compared to no screening(Incremental Cost-Effectiveness Ratio[ICER]:17 790 yuan/QALY).Scenario analyses suggested that initiating HCC screening at the age of 40,as recommended by clinical guidelines,and implementing long-term surveillance based on risk stratification were more cost-effective.Conclusions:For the implementation of HCC screening programs,attention should be paid to improving participation and compliance among the population at risk,incorporating advanced screening methods,improving management efficiency with digital tools,and introducing innovative payment methods to reduce economic burden.

Objective To analyze the incidence of prehypertension (PHTN) and hypertension of male workers in a coal mine and investigate the influencing factors. Methods A total of 10 155 male workers in a coal mine in Shanxi Province were selected as the study subjects using the judgment sampling method. Occupational medical examination was carried out to examine the prevalence of abnormal blood pressure (including PHTN and hypertension) and its influencing factors. Results The prevalence of abnormal blood pressure was 69.9%, with a PHTN prevalence of 44.2% and a hypertension prevalence of 25.7%. The results of multinomial logistic regression analysis showed that the risk of PHTN and hypertension increased with age, drinking frequency and body mass index (all P<0.05). Workers with a pulse rate≥100 times/min had a higher risk of PHTN and hypertension than those with a pulse rate of 60-100 times/min (all P<0.05). The risk of PHTN and hypertension in workers exposed to noise, silica dust or other dust was higher than those without such occupational hazard exposure (all P<0.05). The risk of hypertension in workers with abnormal blood glucose was higher than that in workers with normal blood glucose (P<0.05). Exposure to organic solvents was associated with a higher risk of hypertension (P<0.05). Conclusion The prevalence of PHTN and hypertension among male coal miners in this mine is relatively high. The individual factors such as age, alcohol consumption, pulse rate, and body mass index, along with occupational exposure factors such as noise, silica dust, and other dusts, are influencing factors for PHTN and hypertension.

Objective:To establish a real-time fluorescence quantitative PCR method for detection and identification of Ochrobactrum anthropi ( O.anthropi) and Brucella, and to apply the method in the detection of clinical samples. Methods:The gene nucleotide sequences of 16S ribosomal RNA (16S rRNA) of Ochrobactrum spp. and strains which were adjacent to Ochrobactrum spp. were downloaded from the GenBank database of the National Center for Biotechnology Information (NCBI) website in the United States. A phylogenetic tree was constructed by using MEGA 5.1 software. The primers and probes for the real-time fluorescence quantitative PCR assay, which were specific to O.anthropi were designed using DNAstar (V7.1) software, the sensitivity and specificity of the method was verified. And the method was applied to detect O.anthropi infection in blood samples of clinical patients in pastoral areas. Results:A total of 37 strains of 16S rRNA gene nucleotide sequences from 17 species of Ochrobactrum spp. and 15 strains from 8 species of Brucella spp. were downloaded from the NCBI website. The phylogenetic tree of 16S rRNA gene revealed a high degree of homology (similarity of 100.0%) between O.anthropi, O.cytisi, O.lupini and O.tritici in Ochrobactrum spp. The similarity was 99.1% between O.anthropi and 8 species of Brucella spp. The similarities was 84.5% - 98.6% between O.anthropi and other 13 species of Ochrobactrum spp. The real-time fluorescence quantitative PCR method (nested PCR) was successfully established. For the detection of O.anthropi standard strain DNA, the minimum detection limit of single real-time fluorescence quantitative PCR was 3.67 fg nucleic acid DNA, with a cycle threshold (CT) of 36.40, and a nested PCR detection CT of 14.67, Brucella spp. and other non- Ochrobactrum spp. strains were not detected. Totally 126 blood samples from clinical patients were collected and tested, and the detection rate of O.anthropi was 17.46% (22/126). Conclusion:A real-time fluorescence quantitative PCR method has been established to detect O.anthropi, which has high sensitivity and specificity and can be used for the identification of O.anthropi and Brucella, as well as clinical sample detection.
