Objective: To understand the association between beverage and snack intake and insufficient serum 25 hydroxyvitamin D [25(OH)D] among primary and secondary school students, so as to provide a scientific basis for targeted intervention measures. Methods: From October to December 2021, a stratified random sampling method was used to select 2 477 primary and secondary school students aged 8 to 15 years old from 9 counties in Yunnan Province implemented the Nutrition Improvement Plan for Rural Compulsory Education Students. The intake of beverages and snacks was investigated using the Rural Student Nutrition Monitoring Questionnaire from Chinese Center for Disease Control and Prevention. The snack intake intensity was calculated and classified into no intake, extremely low, low, medium, and high intensity. Serum 25(OH)D levels were measured in the laboratory, and levels <20 ng/mL were defined as insufficient. Chi square tests, LASSO regression, random forest and binary Logistic regression were used to analyze the association between 20 types of beverages and snacks and serum 25(OH)D insufficiency. Results: Insufficient serum 25(OH)D was detected in 564 boys (45.9%) and 855 girls (68.5%), with a total of 1 419 cases (57.3%). Binary Logistic regression results showed that extremely low intake intensity of carbonated beverages ( OR =1.51), plant protein beverages ( OR =1.61), and milk tea beverages ( OR =1.39) increased the risk of insufficient serum 25(OH)D, while protective factors were fruits and vegetables ( OR =0.77) and pure milk and yogurt ( OR =0.74) (all P <0.05). Subgroup analysis showed that extremely low intake intensity of carbonated beverages, milk containing beverages, tea beverages, fruit and vegetable juices, and plant protein beverages increased the risk of insufficient serum 25(OH)D in girls ( OR =2.22, 1.72, 1.67, 1.74, 1.92), and high intake intensity increased the risk of insufficient serum 25(OH)D in boys ( OR =1.73, 1.48, 1.52, 1.49, 1.97) (all P <0.05). Extremely low intake intensity of carbonated beverages, plant protein beverages, and milk tea beverages in junior high school students ( OR =1.92, 2.54, 1.68) and low intake intensity in primary school students ( OR =1.40, 1.33, 1.45) increased the risk of insufficient serum 25(OH)D (all P <0.05). Conclusions Frequent intake of beverages and highly processed snacks increases the risk of insufficient serum 25(OH)D in primary and secondary school students, while natural foods such as fruits, vegetables, pure milk and yogurt can reduce the risk. Girls and junior high school students are more susceptible to these effects.

Maple syrup disease (MSUD) is a rare autosomal recessive disorder caused primarily by mutations of branched-chain keto acid dehydrogenase complex (BCKDC). BCKDC includes at least four pathogenic genes of BCKDHA, BCKDHB, DLD and DBT. The clinical manifestations of MSUD are complex, and the main symptoms at the early stage include difficulty in feeding, drowsiness, change in muscle tone and special urine flavor of maple syrup. As the disease progresses, convulsion, hypoglycemia, coma and systemic failure may occur. MSUD is easily missed or misdiagnosed during the neonatal period. This paper provides a review for recent progress made in research on MSUD including etiology, physiopathology, clinical manifestation, auxiliary examination and treatment, with a particular emphasis on genetic testing and treatment.

To today of its development,the tenacious vitalities of traditional Chinese medicine (TCM) beyond doubt.From this point of view,it has a positive meaning to analyze and understand TCM,from which to find its advantages and characteristics for better improvement and development of TCM-theory,so that better for the benefit of mankind.Therefore,they were discussed from the perspective of philosophy of science with the conclusion as follows:1.It is a major current Chinese medicine theory Features that the conceptual system of metaphysical nature made the organic combination of syndrome differentiation and treatment,and the Chinese herbal medicines and other therapy as a means of feedback to verify and correct TCM's theory.2.The theory of current Chinese medicine is different from the theory of TCM,because its theoretical deduction and its argument are different from the focus of ancient Chinese medicine.These development and innovation in current Chinese medicine needs to be studied and summarized.3.Chinese medicine and Western medicine should be parallel to the two medical theory systems,both of which enrich the prevention and treatment of diseases.4.As an independent medical theory system,Chinese medicine theory must also need to develop and even revolution.And this process depends on the overall level of development and improvement of science and technology.

Objective: To synthesize roxatidine acetate and its salt. Methods: Using orthogonal test method, reactant ratio was made. Roxatidine acetate was synthesized. Excel was used to synthesize data and make statistics chart. Result: Salt of roxatidine ac?etate was synthesized in four steps with overall yield of 28?8%. Conclusion: The process is moderate and simple and the production cost is low.

AIM To explore pharmacokinetics of Berberine in YL2000 in normal and febrile rats. METHODS The levels of Berberine in plasma were measured through HPLC and secondary parameters were obtained by fitting the dose time data of Berberine making use of 3P87 programme. RESULTS In normal and febrile rats, the plasma concentration of Berberine was peaked at (3 4?0 3) h vs (0 3?2 1) h( P
