Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

The pharmaceutical manufacturing model is gradually changing from intermittent manufacturing to continuous manufacturing and intelligent manufacturing. This paper briefly reviewed the supervision and research progress in continuous pharmaceutical manufacturing in China and abroad and described the definition and advantages of continuous pharmaceutical manufacturing. The continuous manufacturing of traditional Chinese medicine(TCM) at the current stage was summarized in the following three terms: the enhancement of the continuity of intermittent manufacturing operations, the integration of continuous equipment to improve physical continuity between units, and the application of advanced process control strategies to improve process continuity. To achieve continuous manufacturing of TCM, the corresponding key technologies, such as material property characterization, process modeling and simulation, process analysis technology, and system integration, were analyzed from the process and equipment, respectively. It was proposed that the continuous manufacturing equipment system should have the characteristics of high speed, high response, and high reliability, "three high(H~3)" for short. Considering the characteristics and current situation of TCM manufacturing, based on the two dimensions of product quality control and production efficiency, a maturity assessment model for continuous manufacturing of TCM, consisting of operation continuity, equipment continuity, process continuity, and quality control continuity, was proposed to provide references for the application of continuous manufacturing technology for TCM. The implementation of continuous manufacturing or the application of key continuous manufacturing technologies in TCM can help to systematically integrate advanced pharmaceutical technology elements and promote the uniformity of TCM quality and the improvement of production efficiency.

Objective To explore the influencing factors of glycemic variability in 217 cases of hospitalized patients with type 2 diabetes. Meth-ods A total of 217 cases of hospitalized patients with type 2 diabetes,whom received continuous glucose monitoring from January 2013 to Janu-ary 2016,were enrolled for the study. The evaluation variables of glycemic variability included mean amplitude of glycemic excursion(MAGE) and standard deviation of blood glucose(SDBG). Results The difference of glycemic variability was compared by gender,age,diabetic duration, HbA1c,BMI. The values of MAGE and SDBG in females were higher than those in males(P<0.05). There was no significant difference between various age groups and various diabetic duration. The level of glycemic variability increased gradually with the extension of HbA 1c(P<0.05). The level of glycemic variability increased gradually with the extension of body mass index(BMI)(P<0.05). Logistic regression analysis showed that gender(OR=0.67,P=0.02),HbA1c(OR=0.8,P=0.02),diastolic blood pressure(OR=0.9,P=0.03),triglycerides(OR=4.6,P=0.007),cholesterol(OR=0.6,P=0.007). HDL-C(OR=0.09,P=0.006)were significant influencing factors of glycemic variability in hospital-ized patients with type 2 diabetes. Conclusion Gender,HbA1c,BMI,and blood fat are significant influencing factors of glycemic variability while age and duration are not related to the glycemic variability in hospitalized patients with type 2 diabetes.

This study investigated the relationship between serum thyrotrophin levels and dyslipidemia in subclinical hypothyroid and euthyroid subjects. A total of 110 subjects with subclinical hypothyroidism and 1,240 euthyroid subjects enrolled in this study. Patients with subclinical hypothyroidism had significantly lower high density lipoprotein cholesterol (HDL-C) levels than those who were euthyroid. The lipid profiles were each categorized and mean thyrotrophin levels were higher in subjects in the dyslipidemia subclasses than subjects in the normal subclasses. Thyrotrophin was positively associated with serum triglyceride and negatively associated with serum HDL-C in women. Thyrotrophin was also positively associated with total cholesterol (TC) in the overweight population along with TC and LDL-C in overweight women. In the euthyroid population, thyrotrophin was positively associated with TC in the overweight population. In conclusion, serum thyrotrophin was correlated with dyslipidemia in subclinical hypothyroid and euthyroid subjects; the correlation was independent of insulin sensitivity.

Objective To verify the criteria proposed by National Academy of Clinical Biochemistry(NACB)guidelines in investigating the factors that affect serum TSH determination, and to determine the reference range of serum TSH in iodine-sufficient areas of China. Methods In 2007, 5 348 inhabitants were enrolled from 3 iodine-sufficient areas of Liaoning Province, and were asked to fulfill the questionnaire. Serum TSH, thyroid peroxidase antibody(TPOAb), and thyroglobulin antibody(TgAb)were determined, and thyroid ultrasonography was carried out. Results The distribution of TSH levels was skewed in healthy people and closely fit the curve of Gaussian distribution after logarithmic transformation. The levels of TSH in subjects of 12-19 years of age were significantly higher than those of other age groups(P＜0.01), and no significant difference was found among the latter groups. TSH level in females [(1.68±1.90)mIU/L] was higher than in males[(1.45±1.92)mIU/L, P＜0.01]. The reference range of TSH was 0.43-4.74 mIU/L in males, and 0.48-5.39 mIU/L in females. Family history of thyroid disease, abnormal thyroid ultrasonography, and positive thyroid antibodies were the factors that influenced TSH level. Conclusion The reference range of serum TSH in iodine-sufficient areas of China is established.

Objective To investigate the relationship between serum thyrotrophin(TSH)and dyslipidemia in subclinical hypothyroid and euthyroid subjects. Methods An epidemiological study on diabetes and thyroid diseases was performed in Dadong community, Shenyang city, in 2007. 110 subjects with subclinical hypothyroidism(SCH)and 1 240 euthyroid subjects were enrolled in the study. Neither history of thyroid diseases nor administration of thyroid-related and lipid-regulating medicines were reported in these subjects. The levels of serum thyroid hormones, lipids, fasting plasma glucose(FPG), and insulin were determined. Results (1)Patients with SCH had significantly lower HDL-C levels than those who were euthyroid.(2)According to the guideline of treatment of adult dyslipidemia in China, the lipid profiles were each categorized. Mean TSH levels were higher in subjects in the dyslipidemia subclass than subjects in the normal subclass. The differences were significant in high LDL-C subclass in overweight individuals. In euthyroid overweight women, mean TSH levels were significantly higher in high LDL-C subclass. In the euthyroid population, TSH was positively associated with total cholesterol in overweight population. The association was not modified by the homestasis model assessment for insulin resistance(HOMA-IR)values.(3)TSH was associated positively with serum triglycerides and negatively with serum HDL-C in women. TSH was positively associated with total cholesterol in overweight population and positively associated with total cholesterol and LDL-C in overweight women after adjustment for age, sex, and body mass index. Conclusion Raised serum TSH seems to be a risk factor of dyslipidemia in subclinical hypothyroid and euthyroid subjects, which is independent of insulin sensitivity.
