Objective To study on the relationship between insulin resistance and thyroid nodule in the patients of normal glucose metabolism. Methods The clinical data of 105 patients of normal glucose metabolism were analyzed. The patients were divided into nodules group (54 patients) and non- nodules group (51 patients). The age, sex, body mass index (BMI), fasting plasma glucose (FPG), postprandial 2 h blood glucose (2 h PG), fasting insulin (FINS), postprandial 2 h (2 h INS), fasting C peptide (FC-P), postprandial 2 h C peptide (2 h C-P), glycosylated hemoglobin (HbA1c), blood uric acid (BUA), homeostatic model assessment insulin resistance index (HOMA-IR) were compared between two groups. According the level of HOMA-IR, 105 patients were divided into different subgroups, the detection rate of thyroid nodules was compared. The influencing factors of thyroid nodules were analyzed by multi-factor Logistic regression analysis. Results The age and sex between two groups had no significant differences (P>0.05). The levels of BMI, BUA, HOMA-IR, FPG, FINS, 2 h INS, FC-P, 2 h C-P and HbA1c in nodules group were significantly higher than those in non-nodules group (P<0.05). The detection rate of thyroid nodules in HOMA-IR 3. 01- 4.00 group (12/14) and HOMA-IR > 4.00 group (20/20) was higher than that in HOMA-IR 0- 1.00 group (0), HOMA-IR 1.01- 2.00 group (39.5%, 17/43) and HOMA-IR 2.01-3.00 group (5/17), there were significant differences (P<0.01). Multi-factor Logistic regression analysis showed that the detection rate of thyroid nodules had positive correlation with levels of HOMA-IR, BUA and BMI (OR=0.278, 0.004 and 0.115, 95%CI 1.695-5.043, 1.001-1.015 and 1.046-1.644). The detection rate of thyroid nodules had no correlation with level of FPG (P>0.05). Conclusions The detection rate of thyroid nodules in HOMA-IR>3.00 patients is significantly higher. The insulin resistance, higher BMI and hyperuricemia are the independent risk factors of thyroid nodules.

Objective To understand the side-effects of cyclophosphamide (CTX) in the treatment of systemic autoimmune diseases and the possible risk factors. Methods Two hundred and forty-one patients with systemic autoimmune diseases were recruited from the Rheumatology Division of Peking University First Hospital during January 1st, 2009 and March 31, 2012. All the patients received oral or intravenous cyclopho-sphamide. The data were collected by medical record review as well as telephone follow-up. Logistic regression analyses were used for statistical analysis. Results Statistical analysis for age, sex, disease, cumulative dose, treatment duration and mode of administration were included in the factor analysis that would impact the CTX related side-effects. Age ( x2=14.8, P=0.002), gender ( x2=11.2, P=0.001), the underlying disease ( x2=26.1, P<0.01), cumulative dose ( x2=9.8, P=0.007) and mode of administration of CTX ( x2=19.5, P<0.01) were all correlated with the incidence of CTX side-effects. Multivariate analysis showed that women [OR=2.32, 95%CI (1.15, 4.70), P=0.02], intravenous-oral sequential use of CTX [OR=5.25, 95%CI (2.30, 11.97), P<0.01] and systemic lupus erythematosus [OR=4.02, 95%CI (2.24, 7.21), P<0.01] as the underlying disease were independent risk factors for CTX side-effects. Conclusion Alopecia, gastrointestinal discomfort and gonads toxicity ware com-monly seen in Chinese patients with systemic autoimmune diseases receiving CTX. Hemor-rhagic cystitis is very rare. Women, intravenous-oral sequential use of CTX and the systemic lupus erythematosus are indepen-dent risk factors for CTX side-effects.

Abstract Incomplete combustion of solid fuels produces a large amount of pollutants, which are associated with the incidence and mortality risks of various chronic diseases, making it one of the significant environmental and public health issues in China. Studies have shown that air pollutants generated by the use of solid fuels in households may increase the risk of diabetes by interfering with glucose metabolism and altering insulin resistance, and may also increase the risk of hypertension by inducing vascular oxidative stress and inflammatory responses. This article reviews relevant literature published domestically and internationally from 2001 to 2024, focusing on the impacts of household solid fuel use on diabetes and hypertension, as well as suggestions for reducing household solid fuel use, providing the reference for the prevention of related chronic diseases.

OBJECTIVE: To investigate the effect of Salvia Miltiorrhiza injection (SMI) on peritoneal dialysis solution (PDS) induced injuries of peritoneal structure and function in a rat model, and to observe the relationship between the failure of peritoneal dialysis and expressions of aquaporin-1 (AQP-1) and zonula occluden-1 (ZO-1) in peritoneal tissues. METHODS: Fifty-six SD rats were randomly divided into normal control group, 1.5% PDS group, 4.25% PDS group, 1.5%PDS+1% SMI group, 1.5%PDS+2% SMI group, 4.25% PDS+1% SMI group and 4.25% PDS+2% SMI group. Two-hour peritoneal dialysis test was performed in rats in different groups by intraperitoneal injection for 8-week. Then rats were killed on the 8th week, and the bloods and peritoneal tissues were gathered. The rate of ultrafiltration, clearance rates of urea nitrogen, creatinine and glucose of peritoneum and content of total protein in PDS were detected. Peritoneal membrane histology was evaluated by light microscopy and transmission electron microscopy. Expressions of ZO-1 and AQP-1 proteins in peritoneal tissues were detected by immunohistochemical method, and AQP-1 protein expression was also detected by Western blotting technique. RESULTS: Compared with normal control group, using of 1.5% PDS and 4.25% PDS caused the changes of structure and function in peritoneum, such as pathological change of peritoneum, decreasing of the rate of ultrafiltration (P<0.05), clearance rates of creatinine and glucose (P<0.01) and the expression of ZO-1 protein (P<0.05), and increasing of the expression of AQP-1 protein (P<0.05). Compared with the simple PDS groups, the pathological damage of peritoneum was lessened and the rate of ultrafiltration and clearance rates of creatinine and glucose were increased in the 1.5% PDS+2% SMI group and 1.5% PDS+2% SMI group. Expression of AQP-1 protein was decreased by 1.5% PDS+2% SMI as compared with 1.5% PDS (P<0.05).[JP] CONCLUSION: SMI can relieve the injuries of function and structure of peritoneum by down-regulating the expression of AQP-1 protein.

The compatibility of kanamycin with sodium citrate for the formulation of kanamycin sulfate injection was determined, including optimization of the amount of sodium citrate in the injection and the sterilization process. An HPLC coupled with an evaporative light scattering detector (ELSD) was used to measure the amount of sodium citrate and the impurity profiles. A validated post-column derivatization HPLC coupled with a fluorescence detector (FLD) was used to determine the correlation between specific impurities in a domestic factory and sodium citrate, and then the formulation was evaluated by HPLC coupled with mass detector (MS) characterization of degradation products. The results show that the amount of sodium citrate in kanamycin sulfate injection from a domestic factory is about 40 times higher than that of the Meiji formulation. Several specific impurities can be detected in solutions heated under simulated sterilization conditions (121 ℃), which were correlated with the amount of sodium citrate. Impurities were characterized by HPLC-MS/MS, and data showed that the identified impurities were interaction products of kanamycin and sodium citrate. These results indicate that greater attention should be directed at formula optimization in domestic factories, as it is crucial to the safety and efficacy of the preparations. Drug-excipient chemical compatibility should also be evaluated in the development of pharmaceutical dosages forms especially when the active pharmaceutical ingredients have a primary amine group.
