Objective To investigate the role of glargine in glucose metabolism improvement and antiinflammation of skeletal muscle in Caveolin-1 silenced type 2 diabetic mice.Methods Multiple low doses of streptozotocin (STZ) intraperitoneal injection and high-fat high-glucose (HFHG) were used to induce type 2 diabetic mice model.The mice were divided into normal control group (NC group) and type 2 diabetic model group (T group).Then according to virus injection and glargine treatment,T group were further divided into type 2 diabetes group (T2DM group),type 2 diabetes with insulin treatment group (insulin group),Caveolin-1 silenced with insulin treatment group (LV-CAV1 group),and scramble virus with insulin treatment group (LV-GFP group).Glucose metabolism was accessed by the fluctuation of blood glucose.TNF-α protein expression in skeletal muscle was detected by Western blot.Results The glycemic control of LV-CAV1 group needed more dosages of glargine (P ＜ 0.05).The expression of TNFαin skeletal muscle was elevated in LV-CAV 1 group than that in LV-GFP and insulin group (P ＜ 0.05).Conclusion The anti-inflammation function and glycemic metabolism improvement of glargine may be associated with the expression of Caveoin-1 in skeletal muscle.

Objective To study the intestinal microflora changes in children with Henoch-Sch?nlein purpura (HSP). Methods The feces of 64 children with HSP (the experimental group) and 25 healthy children (the control group) were collected. 16S rRNA/DNA fluorescent quantitative polymerase chain reaction were performed to detect bacterial content of Lactobacillus, Biifdobacterium and Escherichia coli in feces. Results The amounts of Lactobacillus, and Biifdobacterium in the HSP group were lower than those of the healthy group, and the amounts of E.coli were higher, but the differences were not statistically signiifcant. The amounts of Lactobacillus and Biifdobacterium in the HSP children with gastrointestinal symptoms (abdominal pain, vomiting, e.g.) were signiifcantly lower than those in HSP children without gastrointestinal symptoms and in the healthy group. The difference was signiifcant (P<0.05). Conclusions It suggests that intestinal microlfora in children with HSP in acute phase may exist disorders, especially in the HSP children with gastrointestinal symptoms.

Abstract: Objective　To analyze the epidemiological characteristics of 151 cases of melioidosis and the drug resistance of Burkholderia pseudomallei (BP), in order to provide the basis for diagnosis, treatment and reasonable prevention of melioidosis. Methods　A total of 151 inpatients and outpatients from the Second Affiliated Hospital of Hainan Medical University from January 1, 2013 to August 31, 2022 were collected, and clinical specimens were submitted for examination to isolate and identify BP strains. The clinical data of 151cases of melioidosis and the drug resistance characteristics of pathogenic bacteria were retrospectively analyzed, and using SPSS26.0 software for statistical analysis. Results　Among 151 cases with BP infection, there were 138 males (91.4%) and 13 females (8.6%); the most patients were aged from 45-<60 years old, accounting for 74 cases (49.0%); melioidosis incidence was concentrated in October (19.2%), November (19.2%), August (9.9%) and July (8.6%), and; the number of confirmed cases showed an increasing trend and the time for confirmation was <10 d; Internal medicine system (31.1%), surgery system (26.5%) and intensive care department (20.5%) were the common departments for treating melioidosis; blood (49.0%), sputum (9.9%) and wound secretion (8.6%) were the main clinical specimens for detecting BP; pulmonary infection (68.2%), sepsis (35.1%) and local suppurative infection (23.8%) were the top clinical manifestations in patients with BP infection; the effective rate of treating melioidosis was 74.8%; abnormal liver function was a risk factor for the curative effect of melioidosis (χ2=5.010, P<0.05); the sensitivity rates of BP strains to sulfamethoxazole-trimethoprim (SXT), doxycycline (DOX), imipenem(IPM), ceftazidime (CAZ), amoxicillin/clavulanate (AMC) and tetracycline (TCY) were generally more than 90%, with sensitivities of 98.7%, 97.2%, 96.7%, 94.0%, 93.2% and 90.7%, respectively. Conclusions　It can be concluded that misdiagnosis or missed diagnosis of melioidosis is easy to occur, and the understanding of the epidemiological characteristics and risk factors in this area should be strengthened. The sensitivity of BP to commonly used antibiotics has shown a certain downward trend, clinical use should be standardized, and drug resistance monitoring should be strengthened to improve the efficacy of melioidosis treatment.

· ATM:To analyze bacterial spectrum and drug sensitivity in conjunctival sac of cataract patients of Kazak.
· METHODS:A total of 538 cases of conjunctival sac secretion in cataract patients of Kazak were collected.The samples were cultured and their sensibilities to antibiotics were tested.
· RESULTS: The bacterial culture was positive in 214 cases.The positive rate was 39.8%. The variety of pathogenic bacteria were mainly made up of gram positive cocci ( 88.3%), and most of them were Staphylococcus epidermidis ( 66.4%), followed by Micrococcus(9.8%).Sex had no effect on conjunctival bacteria rate in the cataract patients of Kazak, while age, place of residence had an effect on camier rate. The camier rate of conjunctival bacteria was significantly higher in people over 60 years old than that in people with age between 40 to 59 years old.And the people from city had a significant lower bacteria positive rate than those from countryside and pastoral. Most of grams were sensitive to Vancomycin, Teicoplanin, Rifampicin, Duly cloth mildew mutual and Amikacin, the tolerance was less than 20%, and they usually had higher tolerance to Penicillin, Erythromycin, Tetracycline and Chloramphenicol (>70%) .
·CONCLUSlON:Gram positivecocci is the most common bacteria in conjunctival sac in cataract patients of Kazak. Staphylococcus epidermidis was most common, followed by Micrococcus.The germ-carrying rate of conjunctival SAC in Kazakh population is associated with the patient’s age and area of residence.The clinical use of antibacterial drugs should be strictly grasp the indications, to reduce the incidence of bacterial resistance.
