Network Meta-analysis was conducted to evaluate the efficacy and safety of different traditional Chinese medicine injections combined with conventional western medicine in treatment of cerebral small vessel disease(CSVD). Computerized searches were conducted in PubMed, Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, VIP, and SinoMed for randomized controlled trial(RCT) published in Chinese or English using traditional Chinese medicine injections to treat CSVD. The search time is from the inception to July 15, 2024. Literature screening and statistical analysis were conducted with NoteExpress 3.0.3, RevMan 5.3.5, and Stata 15.1.6. A total of 45 articles were included, involving 3 717 patients, with 1 944 patients in the treatment group and 1 773 patients in the control group. A total of 15 kinds of traditional Chinese medicine injections were involved. Network Meta-analysis indicated that,(1) in terms of improving clinical total effective rate, the best intervention in SUCRA was Ciwujia Injection + conventional western medicine.(2) In terms of reducing NIHSS scores, the best intervention in SUCRA was Xueshuantong Injection + conventional western medicine.(3) In terms of improving ADL scores, the best intervention in SUCRA was Danshen Injection + conventional western medicine.(4) In terms of improving MMSE scores, the best intervention in SUCRA was Xueshauntong Injection + conventional western medicine.(5) In terms of improving MoCA scores, the best intervention in SUCRA was Salvianolate Injection + conventional western medicine.(6) In terms of reducing plasma viscosity(PV), the best intervention in SUCRA was Danhong Injection + conventional western medicine.(7) In terms of reducing the hematocrit, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(8) In terms of reducing fibrinogen, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(9) In terms of reducing erythrocyte sedimentation rate(ESR), the best intervention in SUCRA was Danshen Injection + conventional western medicine.(10) In terms of reducing total cholesterol(TC), triglycerides(TG), and low-density lipoprotein(LDL), the best intervention in SUCRA was Danshen Injection + conventional western medicine. The radar chart results indicated that the advantage of Salvianolate Injection lies in improving cognitive function, while the advantage of Xueshuantong Injection lies in improving neurological function. The advantage of Xuesaitong Injection lies in improving hemodynamic parameters, and the advantage of Danshen Injection lies in improving behavioral ability, hemodynamics, and blood lipid levels. In terms of safety, there was no significant difference in the incidence of adverse reactions between the traditional Chinese medicine injection treatment group and the conventional western medicine group, and no serious adverse reactions occurred. The results showed that the combination of traditional Chinese medicine injections and conventional western medicine can effectively improve the clinical total effective rate, the neurological and cognitive functions, hemodynamic parameters, and blood lipid levels of patients suffering from CSVD. In addition, more double-blind, multi-center, large-sample RCT is needed to verify these findings and to provide more high-quality evidence on the efficacy and safety of traditional Chinese medicine injections for CSVD.

OBJECTIVES:
To investigate the effects of methylenetetrahydrofolate reductase (MTHFR) rs1801133 and γ-glutamyl hydrolase (GGH) rs11545078 gene polymorphisms on plasma concentrations and toxicity following high-dose methotrexate (MTX) therapy in children with acute lymphoblastic leukemia (ALL).
METHODS:
Children with ALL treated at the Xuzhou Children's Hospital of Xuzhou Medical University from January 2021 to April 2024 were selected for this study. Genotypes of MTHFR rs1801133 and GGH rs11545078 were determined using multiplex polymerase chain reaction. MTX plasma concentrations were measured by enzyme-multiplied immunoassay technique, and toxicity was graded according to the Common Terminology Criteria for Adverse Events version 5.0. The relationships between MTHFR rs1801133 and GGH rs11545078 genotypes and both MTX plasma concentrations and associated toxicities were analyzed.
RESULTS:
In the low-risk ALL group, the MTHFR rs1801133 genotype was associated with increased MTX plasma concentrations at 72 hours (P<0.05). In the intermediate- to high-risk group, the MTHFR rs1801133 genotype was associated with increased MTX plasma concentrations at 48 hours (P<0.05), and the GGH rs11545078 genotype was associated with increased MTX plasma concentrations at 48 hours (P<0.05). In the intermediate- to high-risk group, the MTHFR rs1801133 genotype was associated with the occurrence of reduced hemoglobin (P<0.05), and the GGH rs11545078 genotype was associated with the occurrence of thrombocytopenia (P<0.05).
CONCLUSIONS
Detection of MTHFR rs1801133 and GGH rs11545078 genotypes can be used to predict increased MTX plasma concentrations and the occurrence of toxic reactions in high-dose MTX treatment of ALL, enabling timely interventions to enhance safety.

Enamel demineralization, the formation of white spot lesions, is a common issue in clinical orthodontic treatment. The appearance of white spot lesions not only affects the texture and health of dental hard tissues but also impacts the health and aesthetics of teeth after orthodontic treatment. The prevention, diagnosis, and treatment of white spot lesions that occur throughout the orthodontic treatment process involve multiple dental specialties. This expert consensus will focus on providing guiding opinions on the management and prevention of white spot lesions during orthodontic treatment, advocating for proactive prevention, early detection, timely treatment, scientific follow-up, and multidisciplinary management of white spot lesions throughout the orthodontic process, thereby maintaining the dental health of patients during orthodontic treatment.

OBJECTIVE:
This study aimed to explore the association between body mass index (BMI) and mortality based on the 10-year population-based multicenter prospective study.
METHODS:
A general population-based multicenter prospective study was conducted at four sites in rural China between 2013 and 2023. Multivariate Cox proportional hazards models and restricted cubic spline analyses were used to assess the association between BMI and mortality. Stratified analyses were performed based on the individual characteristics of the participants.
RESULTS:
Overall, 19,107 participants with a sum of 163,095 person-years were included and 1,910 participants died. The underweight (< 18.5 kg/m 2) presented an increase in all-cause mortality (adjusted hazards ratio [ aHR] = 2.00, 95% confidence interval [ CI]: 1.66-2.41), while overweight (≥ 24.0 to < 28.0 kg/m 2) and obesity (≥ 28.0 kg/m 2) presented a decrease with an aHR of 0.61 (95% CI: 0.52-0.73) and 0.51 (95% CI: 0.37-0.70), respectively. Overweight ( aHR = 0.76, 95% CI: 0.67-0.86) and mild obesity ( aHR = 0.72, 95% CI: 0.59-0.87) had a positive impact on mortality in people older than 60 years. All-cause mortality decreased rapidly until reaching a BMI of 25.7 kg/m 2 ( aHR = 0.95, 95% CI: 0.92-0.98) and increased slightly above that value, indicating a U-shaped association. The beneficial impact of being overweight on mortality was robust in most subgroups and sensitivity analyses.
CONCLUSION
This study provides additional evidence that overweight and mild obesity may be inversely related to the risk of death in individuals older than 60 years. Therefore, it is essential to consider age differences when formulating health and weight management strategies.

OBJECTIVE:
To investigate the relationship between physical activity and genetic risk and their combined effects on the risk of developing chronic obstructive pulmonary disease.
METHODS:
This prospective cohort study included 318,085 biobank participants from the UK. Physical activity was assessed using the short form of the International Physical Activity Questionnaire. The participants were stratified into low-, intermediate-, and high-genetic-risk groups based on their polygenic risk scores. Multivariate Cox regression models and multiplicative interaction analyses were used.
RESULTS:
During a median follow-up period of 13 years, 9,209 participants were diagnosed with chronic obstructive pulmonary disease. For low genetic risk, compared to low physical activity, the hazard ratios ( HRs) for moderate and high physical activity were 0.853 (95% confidence interval [ CI]: 0.748-0.972) and 0.831 (95% CI: 0.727-0.950), respectively. For intermediate genetic risk, the HRs were 0.829 (95% CI: 0.758-0.905) and 0.835 (95% CI: 0.764-0.914), respectively. For participants with high genetic risk, the HRs were 0.809 (95% CI: 0.746-0.877) and 0.818 (95% CI: 0.754-0.888), respectively. A significant interaction was observed between genetic risk and physical activity.
CONCLUSION
Moderate or high levels of physical activity were associated with a lower risk of developing chronic obstructive pulmonary disease across all genetic risk groups, highlighting the need to tailor activity interventions for genetically susceptible individuals.

Hypertension and osteoporosis(OP)are common diseases in middle-aged and elderly people,and the number of patients with both diseases has gradually increased in recent years.Because the onset of the disease is hidden,it is easy to cause fractures and serious complications of heart,brain and kidney in the later stage,which not only seriously damages the quality of life of patients,but also increases the difficulty of clinical treatment.Therefore,it is particularly necessary to strengthen the research on this disease.More and more studies have found that the disorder of intestinal flora will lead to the occurrence of OP,while the intestinal flora of patients with hypertension is obviously out of balance.Therefore,this paper thinks that intestinal flora may be the key influencing factor of hypertension complicated with OP,and the imbalance of intestinal flora will lead to the imbalance of short-chain fatty acid metabolism,immune inflammatory reaction and increased sympathetic nerve activity,thus causing the imbalance of bone homeostasis and promoting the occurrence of OP.Therefore,it is suggested that regulating intestinal flora may be a new way to intervene hypertension complicated with OP.
