Objective:To investigate the association of blood lipids and body mass index (BMI) with hyperuricemia (HUA) in the elderly.Methods:It was a cross-sectional study. A total of 114 391 elderly individuals received health examinations at primary healthcare institutions in Wujin District from January to December in 2022. The health examination included questionnaire survey, physical examination and laboratory examination. The multivariate logistic regression and restricted cubic spline (RCS) plots were used to analyze the association and dose-response relationship of blood lipid and BMI with HUA. The mediating effect model was used to explore the mediation effect of BMI on the association between blood lipid and HUA.Results:Among the 112 415 subjects, 18 506 (16.46%) were checked with HUA. After adjusting for relevant confounders, total cholesterol (TC) ( OR=1.20, 95% CI: 1.16-1.23), triglyceride (TG) ( OR=1.46, 95% CI: 1.44-1.49), high density lipoprotein cholesterol (HDL-C) ( OR=0.74, 95% CI: 0.73-0.76), low density lipoprotein cholesterol (LDL-C) ( OR=1.14, 95% CI: 1.12-1.15) and BMI ( OR=1.42, 95% CI: 1.39-1.44) were all associated with HUA (all P0.05). The RCS analysis revealed that TG, HDL-C, and LDL-C each exhibited a nonlinear dose-response relationship with HUA, the inflection points was 3.00 mmol/L, 1.57 mmol/L and 2.50 mmol/L, respectively (all P-nonlinear0.001). The results of interaction showed that there were additive interaction between high TC( S=1.27 , 95% CI: 1.17-1.37), high TG( S=1.32 , 95% CI: 1.25-1.40), high LDL-C( S=1.23 , 95% CI: 1.14-1.34) and overweight/obesity with HUA (all P0.05). The results of mediation effect analysis showed that the mediation effect of BMI on the association between blood lipids (HDL-C, LDL-C, TG and TC) and HUA, from high to low, were as follows: 22.5% (95% CI: 20.8%-24.2%), 13.9% (95% CI: 12.0%-16.2%), 13.5% (95% CI: 12.7%-14.4%) and-3.9% (95% CI:-6.6%--1.8%). Conclusion:The blood lipid levels and BMI are positively correlated with HUA in the elderly.

Objective:To evaluate the efficacy and safety of filiform-needle acupuncture(FA)in the treatment of poststroke urinary incontinence(PSUI).Methods:All published papers in PubMed,Excerpta Medica Database(EMBASE),Cochrane Library,Web of Science,China National Knowledge Infrastructure(CNKI),Chongqing VIP Database(VIP),Wanfang Data Knowledge Service Platform(Wanfang),and China Biology Medicine Disc(CBM)were retrieved by computer.The retrieval time was from each database's inception to December 9,2023.Meta-analysis and sensitivity analysis were performed using the Revman V5.4 software,and GARDE evaluation was performed using GRADEpro GDT.Dichotomous variables were analyzed by the relative risk(RR),and weighted mean difference(WMD)was used for continuous variables.Each effect size was expressed as a 95%confidence interval(CI).Results:A total of 14 studies were included,comprising a total of 1 259 patients.The findings of the meta-analysis showed that the improvements of the maximum bladder capacity[WMD=64.63,95%CI(41.73,87.53),P<0.00001],72 h urination frequency[WMD=-5.27,95%CI(-6.40,-4.13),P<0.00001],and 72 h urinary incontinence frequency[WMD=-1.62,95%CI(-2.60,-0.64),P=0.001]in PSUI patients by FA were superior compared to conventional therapy.FA plus rehabilitation therapy(RT)was superior to RT alone in improving the maximum bladder capacity[WMD=35.17,95%CI(28.31,42.03),P<0.00001],the International Consultation on Incontinence questionnaire short form(ICI-Q-SF)score[WMD=-2.66,95%CI(-3.28,-2.05),P<0.00001],and incontinence quality of life questionnaire(I-QOL)score[WMD=8.07,95%CI(3.28,12.32),P=0.0002].The incidence of adverse reactions in FA was higher than that in RT[RR=21.62,95%CI(4.04,115.71),P=0.0003],but the severity was mild and did not affect the integrity of the treatment.Conclusion:FA has better safety,and its improving effect on bladder urinary storage function and urinary incontinence symptoms in patients with PSUI is clear.Combined with RT,it can better improve the quality of life in the patients.However,more high-quality studies are still needed for further updates and verification.

ObjectiveTo explore the evolution principles of symptoms including deficiency， phlegm and blood stasis， and of the functional near-infrared spectroscopy （fNIRS） cerebral hemodynamic characteristics at various stages in patients of Alzheimer's disease. MethodsA total of 497 patients with complaint of memory loss were included， and were divided into subjective cognitive decline （SCD） group （198 participants）， mild cognitive impairment （MCI） group （228 participants） and dementia （AD） group （71 participants）. Neuropsychological evaluation， traditional Chinese medicine （TCM） syndrome investigation， and fNIRS data collection of prefrontal cortex were performed in each group. Descriptive statistics were used to analyze the distribution of TCM syndromes and the difference of TCM syndrome scores in each group； logistic regression was used to analyze the influence of TCM syndromes on the incidence of the patients； association rules were used to analyze the TCM syndromes of the patients； the hemodynamic characteristics of fNIRS in the prefrontal cortex of each group were compared. ResultsKidney essence deficiency syndrome was the dominant syndrome in all stages of AD. There were statistically significant differences in the distribution frequency of kidney essence deficiency， phlegm turbidity obstructing orifices， blood stasis obstructing collaterals， qi and blood deficiency， heat toxin in the interior， and fu-organ stagnation and turbidity retention syndromes among the three groups （P＜0.01）， and the scores of kidney essence deficiency syndrome among the three groups were statistically significant （P＜0.01）. Logistic regression analysis showed that kidney essence deficiency， and qi and blood deficiency syndromes were the main risk factors for the SCD group （P＜0.05）， phlegm turbidity obstructing orifices syndrome was the main risk factor for the MCI group （P＜0.05）， and heat toxin in the interior， and fu-organ stagnation and turbidity retention syndromes were the main risk factors for the AD group （P＜0.05）. The association rule analysis showed that the combination of kidney essence deficiency plus phlegm turbidity obstructing orifices had the highest support （33.33%） in the SCD group， and the combination of kidney essence deficiency plus blood stasis obstructing collaterals had the highest support （32.90% and 52.13%） in both the MCI and AD group. The prefrontal fNIRS results showed that the mean ∆HbO₂ concentration in the left dorsolateral prefrontal cortex （LDLPFC） decreased sequentially among the three groups （P＜0.05）， and the mean ∆HbO₂ concentration in the LDLPFC was negatively correlated with the MoCA score among the three groups （r = -0.142， P＜0.05）. Further analysis showed that the mean ∆HbO₂ concentration in the LDLPFC of patients with kidney essence deficiency syndrome were statistically significant differences among the three groups （P＜0.05）. ConclusionKidney deficiency is the basis of the pathogenesis of AD， and the key brain area damaged is the LDLPFC. Turbid pathogens such as phlegm and blood stasis are the pathological factors that aggravate the disease， and the syndromes of AD show the evolution law of deficiency and excess as “kidney deficiency→phlegm turbidity→blood stasis→turbid toxin”. The changes in prefrontal hemodynamics based on fNIRS are consistent with the changes in the characteristics of symptoms， which can be used to assess the degree of cognitive impairment in AD patients.

Integrase inhibitors (INSTIs) are the newest class of antiretroviral drug which are available to people living with the human immunodeficiency virus (HIV). Since 2007, five types of INSTIs have been marketed: Raltegravir, Elvitegravir, Dolutegravir, Bictegravir and Cabotegravir, all of which were approved by the US Food and Drug Administration (FDA) for use in the initiation of antiretroviral therapy (ART) in treatment-na?ve individuals. Compared with other types of antiretroviral drugs, INSTIs have better efficacy and tolerability, so many countries around the world have listed INSTIs-containing regimens as the preferred regimen for HIV ART. In recent years, with the widespread use of INSTIs, some research data suggest that INSTIs may have some adverse effects (AEs), such as central nervous system symptoms, abnormal lipid metabolism, weight gain, abnormal liver and kidney function, etc. This review summarizes the current use of INSTIs in people living with the HIV, and highlights the clinical efficacy and their AEs among the five types of INSTIs in China.

The specific binding of T cell receptors (TCRs) to antigenic peptides plays a key role in the regulation and mediation of the immune process and provides an essential basis for the development of tumour vaccines. In recent years, studies have mainly focused on TCR prediction of major histocompatibility complex (MHC) class I antigens, but TCR prediction of MHC class II antigens has not been sufficiently investigated and there is still much room for improvement. In this study, the combination of MHC class II antigen peptide and TCR prediction was investigated using the ProtT5 grand model to explore its feature extraction capability. In addition, the model was fine-tuned to retain the underlying features of the model, and a feed-forward neural network structure was constructed for fusion to achieve the prediction model. The experimental results showed that the method proposed in this study performed better than the traditional methods, with a prediction accuracy of 0.96 and an AUC of 0.93, which verifies the effectiveness of the model proposed in this paper.

Objective:Healthy life expectancy (HLE), which combines life expectancy with health, is an essential comprehensive measure of life length and quality. This article aimed to systematically review the methods for defining and measuring HLE and describe application studies published, providing a reference for decision makers to select and develop methods suitable for China's conditions to measure HLE.Methods:Seven Chinese and English literature databases were searched up to May 7, 2022, and several related reviews and bibliography were manually retrieved. Systematic reviews and empirical research were included concerning HLE indicators and measurement of HLE. Information including the study area, type of the study, study population, HLE index, measurement method, data sources, and results from application studies published in the last five years were extracted. The evolution of the definition of HLE, the scope of different indicators, the measurement scale of health, and measurement methods, were all collected. Results of the empirical research related to measurement methods of indicators were summarized. The study followed the scoping review framework and was written according to the PRISMA-ScR statement.Results:A total of 84 articles were included, including 13 reviews, 17 original studies related to HLE index definition, ten original studies related to index measurement, and 44 empirical studies conducted in the past five years. There were as many as 20 indicators related to HLE, and each scale had its emphasis. A total of ten methods measuring HLE were identified, which vary in the definition of health, whether using weight, and the data type. The most commonly used indicators in the past five years were disability-free life expectancy and HLE. For the method of HLE calculation, Sullivan's method was mainly used for cross-sectional data, and the multistate life table was mainly used for longitudinal data.Conclusions:There are various definitions and measurement methods of HLE, but none are suitable for all scenarios. To summarize the HLE concept, health evaluation techniques, measurement methods, and application studies published worldwide can provide a reference for the localization of HLE measurement in China.

Objective:To characterize the epidemiology of severe hand, foot and mouth disease (HFMD) in China from 2008 to 2018 and provide evidence for the prevention and control of severe HFMD.Methods:The incidence data of severe HFMD cases from 2008 to 2018 were collected from the National Notifiable Infectious Diseases Reporting System of Chinese Center for Disease Control and Prevention. Descriptive epidemiological methods were used to analyze distributions, pathogen constituent and change of severe HFMD. Joinpoint regression model was used to analyze the trends of severity rate, proportion of severe cases and severe fatality rate.Results:From 2008 to 2018, a total of 157 065 cases of severe HFMD were reported in China, with an average annual case-severity rate of 1.05/100 000, a severe case proportion of 0.76 % and a severity-fatality rate of 2.34 %. The severity rate and the proportion of severe cases showed a downward trend after 2010, and severe fatality rate decreased significantly after 2014. The severe cases mainly occurred in infants aged ≤3 years (91.47 %), more boys were affected than girls (1.78∶1). The median age of severe HFMD cases caused by EV-A71 was highest (1.99 years) and increased year by year, other enterovirus infection cases accounted for a higher proportion in infants aged ≤1 year (66.56 %). The incidence peak occurred during April-July, other enteroviruses replaced EV-A71 as the predominant serotype in 2018 (61.97 %). The incidence of severe HFMD were high in some provinces in southwestern, central and eastern China. Conclusion:The overall severity rate, proportion of severe cases and severe fatality rate of HFMD in the mainland of China have shown a downward trend. The predominant pathogen in some provinces has changed from EV-A71 to other enteroviruses. It is necessary to strengthen the prevention and control of HFMD in key population, high incidence seasons and areas and carry out the surveillance of various pathogens of HFMD.

Objective:To evaluate the incidence intensity of hand, foot, and mouth disease (HFMD) in 2018/2019 season in southern China by Moving Epidemic Method (MEM), and compare the intensity among provinces, so as to provide basis for optimizing the allocation of public health resources.Methods:The weekly incidence data of HFMD of children under 5 years old in 15 provinces of southern China from March 1, 2012 to February 28, 2019 were collected from Disease Surveillance Reporting System of Chinese Center for Disease Control and Prevention, and the epidemic intensity threshold of each province in southern China during this period was calculated and evaluated by MEM.Results:In the first incidence peak of 2018/2019 HFMD season, in 15 provinces in the south China, 6 provinces (Jiangsu, Zhejiang, Jiangxi, Chongqing, Sichuan and Yunnan) reported very high incidence rates in children under 5 years old while Guangdong, Guangxi and Hainan provinces had low incidence level. In the second incidence peak, the incidences in 6 provinces (Shanghai, Jiangsu, Zhejiang, Chongqing, Sichuan and Yunnan) reached very high levels. The incidences in remaining provinces also reached medium or high levels. In most provinces, the thresholds in the first incidence peak were higher than those in the second incidence peak, but Chongqing and Sichuan were different. The results of model validation showed that the sensitivity and specificity of MEM were higher than 70% except for Hainan, Chongqing and Yunnan.Conclusions:For southern provinces with two incidence peaks in HFMD season, MEM can be used to determine the epidemic intensity thresholds of different incidence peaks by dividing the disease season to analyze the incidence intensity of HFMD in different stages. The epidemic intensity threshold established by MEM integrates the historical data, and the province (city) with extremely high epidemic level identified represents that the province (city) has an abnormal increase compared with the historical incidence level, which requires more attention from all areas and timely implementation of prevention and control measures.
