ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong （BL 40）" on neuropathic pain in a rat model of chronic constriction injury （CCI） of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups （8 rats in each group）， sham-operated group， model group， Tuina group， and blockade group. The CCI model was established in the model group， Tuina group， and the blockade group by ligating the sciatic nerve with catgut， while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14， rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong （BL 40）" using a dynamic pressure distribution measurement system （5 N pressure， 2 Hz frequency， 10 min per session， once daily）. The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline （10 mg/kg） once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold （MWT） and paw withdrawal latency （PWL） were measured before surgery and on day 3， 7， 10， and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair， measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 （Iba-1）， CD206， CD68， interleukin-10 （IL-10）， and β-endorphin （β-EP） precursor pro-opiomelanocortin （POMC） in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group， the model group showed significantly reduced MWT and PWL on day 3， 7， 10， and 14 （P＜0.01）. Compared with the model group， the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 （P＜0.05）. Compared with the Tuina group， the blockade group exhibited higher MWT on day 7， 10， and 14， and higher PWL on day 10 （P＜0.05）. Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group， while the model group exhibited myelin collapse， distortion， and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse， whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group， the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn （P＜0.05 or P＜0.01）. Compared with the model group， the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally， the Tuina group showed elevated levels of CD206， IL-10， and POMC， whereas the blockade group had decreased CD206 levels （P＜0.05）. ConclusionTuina at "Weizhong （BL 40）" alleviates neuropathic pain in CCI rats， potentially by regulating microglial activation in the spinal cord， inhibiting M1 polarization while promoting M2 polarization， and activating the IL-10/β-EP pathway to exert analgesic effects.

Objective To analyze the epidemiological characteristics of acute respiratory infections(ARIs)during the autumn-winter season in Beijing,providing evidence for the prevention,control,diagnosis,and treatment of ARIs.Methods A convenience sampling method was employed,enrolling patients who visited Peking Union Medical College Hospital(PUMCH)between September 2023 and February 2024 due to ARIs.Na-sopharyngeal swabs were collected,and real-time fluorescence quantitative PCR was used to detect six common respiratory pathogens[influenza A virus(FluA),influenza B virus(FluB),human rhinovirus(HRV),Myco-plasma pneumoniae(MP),respiratory syncytial virus(RSV),and adenovirus(ADV)],as well as SARS-CoV-2 infection.The distribution patterns of pathogen infections were analyzed.Results A total of 5556 eligible patients were included.The overall positivity rate for the six common respiratory pathogens was 63.7％,with sin-gle-pathogen positivity at 54.0％,dual-pathogen positivity at 8.9％,and triple or more pathogen positivity at 0.7％.The predominant pathogens detected were FluA(16.1％)and RSV(15.7％),followed by ADV(11.1％),MP(11.1％),HRV(10.0％),and FluB(10.0％).No significant difference in overall pathogen positivity was observed between genders.However,significant differences were found between autumn and winter(x2=34.617,P＜0.001)and among pediatric,young/middle-aged,and elderly patients(x2=422.38,P＜0.001).Specifically,MP(x2=8.647,P=0.003),FluA(x2=131.932,P＜0.001),and HRV(x2=174.199,P＜0.001)exhibited significantly higher positivity rates in autumn than in winter,whereas FluB was more prevalent in winter(x2=287.894,P＜0.001).In pediatric patients,MP,RSV,HRV,and ADV positivity rates were significantly higher than in young/middle-aged and elderly patients(all P＜0.001),whereas FluB was more common in young/middle-aged patients(both P＜0.001).The positivity rates of the six common respiratory pathogens significantly declined during the SARS-CoV-2 epidemic period,exhibiting an asynchronous seasonal pattern.Conclusions The prevalence of respiratory pathogens in Beijing is associated with age and season.Tar-geted preventive measures should be implemented in different seasons and for key populations.

Objective:To evaluate the diagnostic efficacy and practicality of the Jaundice color card (JCard) as a screening tool for neonatal jaundice.Methods:Following the standards for reporting of diagnostic accuracy studies (STARD) statement, a multicenter prospective study was conducted in 9 hospitals in China from October 2019 to September 2021. A total of 845 newborns who were admitted to the hospital or outpatient department for liver function testing due to their own diseases. The inclusion criteria were a gestational age of ≥35 weeks, a birth weight of ≥2 000 g, and an age of ≤28 days. The neonate′s parents used the JCard to measure jaundice at the neonate′s cheek. Within 2 hours of the JCard measurement, transcutaneous bilirubin (TcB) was measured with a JH20-1B device and total serum bilirubin (TSB) was detected. The Pearson′s correlation analysis, Bland-Altman plots and the receiver operating characteristic (ROC) curve were used for statistic analysis.Results:Out of the 854 newborns, 445 were male and 409 were female; 46 were born at 35-36 weeks of gestational age and 808 were born at ≥37 weeks of gestational age. Additionally, 432 cases were aged 0-3 days, 236 cases were aged 4-7 days, and 186 cases were aged 8-28 days. The TSB level was (227.4±89.6) μmol/L, with a range of 23.7-717.0 μmol/L. The JCard level was (221.4±77.0) μmol/L and the TcB level was (252.5±76.0) μmol/L. Both the JCard and TcB values showed good correlation ( r=0.77 and 0.80, respectively) and agreements (96.0% (820/854) and 95.2% (813/854) of samples fell within the 95% limits of agreement, respectively) with TSB. The JCard value of 12 had a sensitivity of 0.93 and specificity of 0.75 for identifying a TSB ≥205.2?μmol/L, and a sensitivity of 1.00 and specificity of 0.35 for identifying a TSB ≥342.0?μmol/L. The TcB value of 205.2?μmol/L had a sensitivity of 0.97 and specificity of 0.60 for identifying TSB levels of 205.2 μmol/L, and a sensitivity of 1.00 and specificity of 0.26 for identifying TSB levels of 342.0 μmol/L. The areas under the ROC curve (AUC) of JCard for identifying TSB levels of 153.9, 205.2, 256.5, and 342.0 μmol/L were 0.96, 0.92, 0.83, and 0.83, respectively. The AUC of TcB were 0.94, 0.91, 0.86, and 0.87, respectively. There were both no significant differences between the AUC of JCard and TcB in identifying TSB levels of 153.9 and 205.2 μmol/L (both P>0.05). However, the AUC of JCard were both lower than those of TcB in identifying TSB levels of 256.5 and 342.0 μmol/L (both P<0.05). Conclusions:JCard can be used to classify different levels of bilirubin, but its diagnostic efficacy decreases with increasing bilirubin levels. When TSB level are ≤205.2 μmol/L, its diagnostic efficacy is equivalent to that of the JH20-1B. To prevent the misdiagnosis of severe jaundice, it is recommended that parents use a low JCard score, such as 12, to identify severe hyperbilirubinemia (TSB ≥342.0 μmol/L).

Objective:To explore the sleep status and impact factor analysis of patients in clinical trials of antineoplastic drugs, and provide a basis for improving the sleep status and impact analysis of patients in clinical trials of antineoplastic drugs.Methods:From April to May 2023, 107 oncology patients in the Phase I Clinical Trial Ward of the Affiliated East Hospital of Tongji University were selected as the research objects by convenient sampling method. The general information questionnaire, Pittsburgh Sleep Quality Index Scale (PSQI), Numeric rating scale (NRS), Generalized Anxiety Disorder Scale (GAD-7) and Depression Self-Ration Tool Scale (PHQ-9). Multivariate Logistic regression analysis methods were used to carry out a cross-sectional investigation and the relevant factors affecting patients′sleep.Results:Totally 103 questionnaires were effectively collected. The 103 patients′ age ranged from 20 to 75 years old, including 61 males and 42 females. 47.57% (49/103) patients in clinical trials of antineoplastic drugs had abnormal sleep. The average score of patients (PSQI) (7.66 ± 3.93) was higher than the average score of the domestic norm (3.88 ± 2.52), and there was significant statistical difference ( t = 9.76, P<0.01). Logistic regression analysis showed that pain ( OR = 3.004, 95% CI 1.135-7.948, P<0.05) and trial cycle ( OR = 0.432, 95% CI 0.191-0.978, P<0.05) were significant risk factors for abnormal sleep quality. Conclusions:The incidence of abnormal sleep quality in patients of clinical trials of antineoplastic drugs is high, but the sleep quality is poor. The factors that affect the sleep quality of patients in clinical trials of antineoplastic drugs are mainly related to the patient′s trial cycle and cancer pain. According to these characteristics, individualized programs should be developed to improve the sleep quality of patients with advanced cancer, so as to improve the quality of life of patients with advanced cancer.

Overweight and obesity have emerged as a significant public health concern globally.While factors such as genetics,diet,and physical activity are insufficient to fully account for the rise in overweight and obesity,recent studies have indicated a link between environmental pollutants and the development of obesity.Microplastics,a novel type of environmental pollutant,are pervasive in various environmental media and daily life,entering organisms through multiple pathways including the digestive tract,respiratory tract,skin,among others.Evidence from studies has revealed the presence of microplastics in human tissues,organs,and biological samples,suggesting potential health risks to humans.This review outlines the pathways and distribution of microplastics within the human body while summarizing current research progress in relation to obesity.This article aims to raise awareness within society regarding the detrimental effects of microplastics and provide a theoretical foundation for medical professionals addressing public health issues.

BACKGROUND:Resistance exercise increases muscle mass and improves muscle strength,but there is a lack of conclusive evidence on its effects on body composition.Controversial results from randomized controlled trials and multiple Meta-analyses pose a problem for clinical decisions on exercise interventions. OBJECTIVE:Based on the methodological paradigm of umbrella review,to explore the efficacy and safety of resistance exercise in improving the body composition of overweight and obese people. METHODS:We searched PubMed,Cochrane Library,Web of Science,and CNKI for systematic reviews on the effect of resistance exercise in overweight and obese people published from database inception to August 31,2022.Chinese search terms included"anti-resistance,resistance,self-weight,Meta,Meta-analysis,body composition,body fat percentage,fat mass,lean body mass,body mass."English search terms included"resistance training,strength training,weight-lifting strengthening program,body composition,body fat distribution,Meta-analysis,data pooling,overviews,clinical trial,clinical trial overviews."PRISMA was used to evaluate the methodological quality of the included studies,and a GRADE evaluation system was used to grade the quality of evidence. RESULTS AND CONCLUSION:A total of 14 Meta-analyses were included,and GRADE evidence quality evaluation showed that 2 outcome indicators were intermediate,12 were low,and 14 were extremely low.Compared with the control group,23 of the 32 outcome measures showed significant improvement.The intervention effect of resistance exercise on body fat percentage has reached a consensus,but the intervention effects on lean body mass,body mass index and visceral fat still need further confirmation.Resistance exercise is an effective and safe method to improve the body composition of overweight and obese people.The overall quality of the research and the evidence quality of the outcome indicators included in the systematic evaluation are generally low.In the future,the initial state,exercise goal and willingness of the subjects should be fully combined on the basis of clarifying the sample characteristics and refining the scheme design.Through multiple,scientific and personalized exercise prescription designs of water,air and elastic resistance,the safety and compliance of resistance exercise can be improved,providing clear evidence-based support and decision-making basis for resistance exercise intervention.

OBJECTIVE: To analyze variants of SMN gene in a Chinese pedigree affected with Spinal muscular atrophy (SMA). METHODS: A Chinese pedigree diagnosed at the Nanchang First Hospital in January 2020 was selected as the study subject. Peripheral blood samples were collected for the extraction of DNA. All exons of the SMN gene were detected by multiple ligation-dependent probe amplification (MLPA). Potential variants of the SMN gene were also detected by Whole exome sequencing (WES), and the result was verified by Sanger sequencing. cDNA extracted from fresh blood sample was used as a template to verify the location of variant on the SMN genes. RESULTS: The proband was found to harbor a heterozygous deletion of the SMN1 Exon7+Exon8, and a heterozygous c.81G>A variant. The SMN1 Exon7+Exon8 deletion was inherited from her father and grandmother, whilst the c.81G>A variant was inherited from her mother and maternal grandfather. Her aunt was also a carrier of the heterozygous deletion, while her paternal aunt, her husband, and their daughter were not. cDNA amplification and Sanger sequencing confirmed that the c.81G>A variant was located in the SMN1 gene. CONCLUSION MLPA combined with NGS and Sanger sequencing can identify compound heterozygous variants of the SMN gene in the SMA patients.
