RESUMO
Objective:To explore the clinical characteristics and risk factors of concurrent infection in adult patients with hypopituitarism (HP).Methods:Clinical data of patients diagnosed with HP in Fuyang People′s Hospital from October 2016 to August 2020 were collected. Patients were divided into infected group and non-infected group according to whether they were co-infected, and the differences in clinical characteristics between the two groups were compared. The risk factors of infection in HP patients were analyzed by binary logistic regression.Results:The top three clinical manifestations of 64 HP patients were decreased libido; lack of energy, fear of cold, and poor appetite; hyponatremia. Etiological analysis of 64 HP patients: 23 cases of Sheehan′s syndrome, 14 cases of postoperative brain tumors (pituitary adenoma, craniopharyngioma, meningioma), 8 cases of idiopathic, 7 cases of pituitary adenoma, 8 cases of pituitary volume and morphology changes, and 4 cases of empty sella turcica. 40.32%(25/62) of patients with adrenal axis dysfunction received glucocorticoid replacement therapy, with 80%(20/25) receiving prednisone and 20%(5/25) receiving hydrocortisone. The replacement dose was 2.5-25(6.77±3.90)mg of prednisone equivalent dose. 37.70%(23/61) of patients with low thyroid axis function received thyroid hormone replacement therapy, of which 52.17%(12/23) free thyroxine (FT4) levels were still lower than the lower normal limit. 20%(2/10) of males ≤60 years old and 5.56%(1/18) of females≤50 years old received hormone replacement therapy for patients with hypogonadism of the gonadal axis. Among 64 HP patients included, 29 were co-infected (infected group) and 35 were not co-infected (non infected group). There was no significant difference between the infected group and the non infected group in gender, etiology, number of pituitary axis involved, glucocorticoid replacement therapy dose, thyroid hormone replacement therapy dose, and sex hormone replacement therapy rate (all P>0.05). Compared with the non infected group, the infected group was older, had a longer course of disease, lower diastolic blood pressure (DBP) and albumin levels, with statistically significant difference (all P<0.05), while the other indicators showed no statistically significant difference (all P>0.05). The results of binary logistic regression analysis showed that age, course of disease, occupation, and albumin level were the influencing factors of HP complicated infection (all P<0.05). Conclusions:The most common cause of pituitary dysfunction in adults is Sheehan′s syndrome; Adult HP patients who are older, have a longer course of disease, work as farmers, and have hypoalbuminemia are more likely to develop concurrent infections.
RESUMO
Objective:To investigate the value of renal glucose threshold and related factors in patients with type 2 diabetes mellitus.Methods:According to the cut-off point of normal renal glucose threshold(RT G 8.9-10 mmol/L), 107 patients with type 2 diabetes mellitus hospitalized in the Endocrinology Department of our hospital were divided into three groups: high RT G group(RT G>10 mmol/L), medium RT G group(8.9 mmol/L≤RT G≤10 mmol/L), and low RT G group(RT G<8.9 mmol/L). The clinical data and biochemical characteristics of each group were collected and analyzed. Results:The proportions of patients with high, medium, and low RT G of type 2 diabetes mellitus were 56%, 29%, and 15%, respectively. There were significant differences in RT G value, age, course of disease, body mass index(BMI), fasting plasma glucose(FPG), HbA 1C, total cholesterol(TC), serum creatinine, mean blood glucose(MBG), and 24-hour urine glucose between high and medium RT G groups. RT G, gender, BMI, FPG, HbA 1C, TC, and MBG in patients with high RT G group were different from those in low RT G group. Only RT G revealed a difference between medium and low RT G groups. Correlation analysis showed that RT G was positively correlated with gender, age, BMI, HbA 1C, TC, and low density lipoprotein-cholesterol(LDL-C). Regression analysis showed that BMI, HbA 1C, and LDL-C were the related factors affecting the RT G of patients with type 2 diabetes. Conclusion:There is a larger proportion of patients with high RT G in type 2 diabetes mellitus. Their BMI, HbA 1C, and LDL-C are associated with RT G in the patients with type 2 diabetes mellitus.
RESUMO
Objective:To investigated the effects of storage temperature and storage state on the immunoregulatory activities of wild Artemisia rupestris L. crude polysaccharides (WARCP) and cultivated Artemisia rupestris L. crude polysaccharides (CARCP). Explore the optimal storage conditions for WARCP and CARCP.Methods:WARCP and CARCP were stored at different temperatures (4, -20 and -80 ℃) and in different states (powder and solution) for 6 months. Different doses (10, 50, 100 μg/ml) of WARCP and CARCP were used to stimulate mouse bone marrow dendritic cells (DCs) for 24 h in vitro. The lipopolysaccharide with a dose of 100 ng/ml were used as positive control, and RPMI-1640 medium was used as negative control. Flow cytometry was used to detect the proportions of CD40 and CD86 on the surface of DCs.Results:At different temperatures, the differences in immunomodulatory activity of WARCP and CARCP stored in powder state and WARCP stored in solution state were not statistically significant (all P>0.05). The immunomodulatory activities of CARCP stored in solution state at -20 ℃ and -80 ℃ were significantly better than that stored at 4 ℃ (all P<0.05). Conclusions:After 6 months of storage, the immunomodulatory activity of WARCP and CARCP is not affected by the storage state, and can maintain good immunomodulatory activity at different storage temperatures.

Objective To study the effects of aqueous extracts of cultivated Cistanche deserticola Y. C. Ma (AECCD) on T cell responses and the duration of antibody response and to investigate its immunoen-hancing activities in mice. Methods Two batches of female ICR mice were used in this study with 30 from each batch. Each batch of mice was randomly divided into six groups (n=5). Low, medium and high doses of AECCD in combination with ovalbumin ( OVA) were used to set up three experimental groups, while 0. 9% NaCl, OVA alone and aluminium adjuvant were respectively used as blank, negative and positive controls. All mice were intramuscularly injected twice at an interval of two weeks. Flow cytometry was used to detect the ex-pression of T lymphocyte subsets, cytokines and surface molecules of dendritic cells (DC). Indirect ELISA was used to detect IgG antibody levels. Results AECCD could significantly increase the percentage of CD4+and CD8+T lymphocytes in spleen (P<0. 05), up-regulate the expression of CD4+CD44+and CD8+CD44+effector T lymphocytes (P<0. 05), promote the secretion of IFN-γ in T lymphocytes and enhance the expression of CD40 and CD80 on the surface of DC (P<0. 05). ELISA results showed that high-dose AECCD could significantly prolong the duration of IgG antibody response induced by OVA (P<0. 05). Conclusion AECCD could en-hance the T lymphocyte immune response induced by OVA and keep it maintained at a high level, which might help to improve the body′s immune response.
RESUMO
Objective To investigate the immunopotentiating effects of cultivated Cistanche deser-ticola (C.deserticola) crude polysaccharides (CCDCP) as an adjuvant on the model antigen ovalbumin (OVA). Methods Low,medium and high doses of CCDCP in combination with OVA were intramuscularly injected twice into ICR mice at an interval of two weeks,respectively. Aluminum adjuvant was used to set up positive control group. Levels of IgG,IgG1 and IgG2a antibodies were detected by ELISA. Splenocyte prolif-eration was detected by MTT assay. Growth conditions of the immunized mice were observed. Results IgG level was significantly increased in the high dose group 7 days after the first immunization(P<0.05),espe-cially on the 21st and 28th days (P<0.01) as compared with that of the aluminum adjuvant group. High dose of CCDCP in combination with OVA significantly up-regulated the levels of IgG1 and IgG2a in mice as compared with immunization with OVA alone (P<0.05). Moreover, IgG2a level in mice immunized with high dose of CCDCP and OVA was higher than that of the aluminum adjuvant group(P<0.05). Splenocyte proliferation was significantly enhanced in the medium and low dose groups in comparison with that of the OVA group (P<0.05) and the aluminum adjuvant group (P<0.01). No significant difference in mouse body weight was observed in different groups(P>0.05). Conclusion CCDCP as an adjuvant of OVA pro-tein vaccine can enhance Th1 and Th2 immune responses,especially the early antibody production and Th1 immune response. These results will provide some information for further studies of CCDCP as a vaccine ad-juvant.
RESUMO
Objective To explore the effect of smoking on the triglyceride ( TG ) , cholesterol ( TC ) , high density lipoprotein-cholesterol(HDL-C) and low density lipoprotein-cholesterol(LDL-C) with the male type 2 diabetes. Methods Selected 144 male patients with type 2 diabetes, then divided them into four groups, including non-smokers, former smokers,current mild(≤20 per day) smokers and current heavy ( >20 per day) smokers. All of them were investigated about the age, diabetes pathogenesis, exercise, diet, smoking, lipid-lowering drugs used and checked with TG, TC, HDL-C, LDL-C and so on. The difference of TG, TC, HDL-C, LDL-C among these four groups was compared by the methods of covariance analysis, regression analysis and partial correlation to evalu-ate the relationships of smoking with blood lipid. Results TG of heavy smokers was higher than the non-smokers and HDL-C was lower after correcting the effects of other possibly relative factors(P<0. 05). HDL-C of the former smokers was higher than smokers and TG was lower than heavy smokers(P<0. 05). Smoking was an independent risk factor for HDL-C ( P<0. 05 ,β= -0. 213 ) , and there was a significantly negative relationship between daily cigarette consumption and HDL-C ( r= -0. 223 , P<0. 05 ) . Conclusion Smoking is an important risk factor for the diabetic male patients’ metabolism of the TG and HDL-C,independent of age, body mass index, blood pres-sure,exercise,diabetes pathogenesis, percentage of body fat and blood glucose. Smoking promotes the type 2 diabet-ics’ disorder of blood lipid and smoking cessation is of significance for the diabetics’ regulation of blood lipids.
