Objective To study the expression of neuroglobulin(Ngb) in cortex of frontal lobe,hippocampus,cerebrospinal fluid(CSF) and plasma of rats during the process of brain edema induced by endotoxin(LPS).Methods Seventy SD rats were randomly divided into the control group(n=10) and the LPS groups(10 each at six time points).An intraventricular injection of LPS(0.1mg/kg,0.2ml) was given to rats in LPS groups,while the same amount of normal saline was given in control group.The plasma,CSF,hippocampus and the cortex of frontal lobe of rats were collected 3,6,12,24,48 and 72 hours after the injection.Ngb was detected by ELISA,Western blotting and immunohistochemical(IHC) method.The brain water content was measured by wet/dry method.The swelling of organelles in hippocampus and the cortex of frontal lobe were observed by transmission electron microscopy(TEM).Results The brain water content was significantly higher in LPS groups than in control group(P

One hundred and twenty four patients with type 2 diabetes mellitus (T2DM) admitted to the Department of Endocrinology of Chuzhou First People's Hospital from April to October 2019 whose blood glucose levels were not controlled after treatment with metformin (2.0 g/d) for more than 3 months were enrolled in the study. The patients were randomly divided into oral drug group and liraglutide group with 62 cases in each group. On the basis of metformin, the oral drug group was treated with acarbose (300 mg/d); the liraglutide group was treated with liraglutide (1.2 mg/d). The course of treatment was 3 months. The body weight, fasting blood glucose (FPG), 2-h postprandial blood glucose (2 hPG), glycosylated hemoglobin (HbA1c), cholesterol (TC) and triglyceride (TG) levels were compared between the two groups before and after treatment, and the gastrointestinal symptoms and the incidence of hypoglycemia were analyzed. After 3-month treatment the body weight, FPG, 2 hPG, HbA1c of the two groups were lower than the baseline levels ( P<0.05). Compared with the oral group, the body weight, FPG, 2 hPG, HbA1c and TG in liraglutide group were more markedly decreased ( P<0.05). The gastrointestinal reaction of liraglutide group was significantly higher than that of the oral drug group, and there was no hypoglycemia in both groups. The data indicate that liraglutide combined with metformin can significantly improve the blood glucose, blood lipid and body weight of T2DM patients and no hypoglycemia occurs during the treatment.

OBJECTIVETo explore the effect of SF-36 scale being applied in different countries under different culture and to describe the quality of life of pulmonary tuberculosis patients in China and Thailand.

METHODSSF-36 scale was applied to pulmonary tuberculosis patients in both countries using face to face interview.

RESULTSMany coefficients among domains were greater than 0.5 when quality of life of tuberculosis patient in both countries was measured. Cronbach's coefficient of all domains were greater than 0.7 for tuberculosis patients in China while cronbach's Coefficient of most domains were equal or greater than 0.7 for tuberculosis patients in Thailand except for vitality and social domains. The score of social domain for patients in Thailand was greater than that of China.

CONCLUSIONStructure validity was not good for tuberculosis patients in both countries since there were some items overlapped in different domains. However, the reliability was good for measuring quality of life of tuberculosis patients both in China and in Thailand.

Intravenous leiomyomatosis (IVL) is a rare benign neoplasm which originates from the smooth muscle cells and is usually confined to the pelvic venous system. Rarely, intracaval and intracardiac extension has been described. Death can occur as a result of intracardiac involvement. We reported 4 cases of IVL with right heart involvement (intracardiac leiomyomatosis, ICL). Three of them suffered recurrent sudden syncope, and the other one was totally asymptomatic. All of them were successfully treated through one-stage operation under extracorporeal circulation.

Background Intravitreal injection of triamcinolone acetonide (TA) can effectively eliminate central vein occlusion macular edema and improve visual acuity, and photopic negative response (PhNR) can reflect the inner retinal function of RGCs and their axons. It is possible there is a correlation between these two observations.Objective This study was to evaluate the changes of PhNR of flash electroretinogram (F-ERG) after intravitreal injection of TA for macular edema in central retinal vein occlusion ( CRVO ). Methods Thirteen eyes of 12 patients with macular edema caused by CRVO received an injection of 0. 1 ml (4 rg) of TA. PhNR,visual acuity and retinal thickness of macular area were assessed with Roland RETI scan 3. 15 system,decimal visual chart and Stratus optical coherence tomography (OCT) before and 4 weeks after the administration of TA. Written informed consent was obtained from each subject before any medical procedure. Results Visual acuity was improved in 12 eyes and stable in 1 eye 4 weeks following the intravitreal injection of TA. OCT showed that the retinal thickness of the macular area was reduced ;meanwhile,elevation of the amplitude of PhNR also was seen in the F-ERG after the administration of TA in comparison with before the administration of TA. The calculated results determined that the visual acuities were 0. 32t0. 12 and 0. 48±0. 09 (t=6. 325 ,P=0. 000) ,and the retinal thickness values of the macular area were (459.46± 131.31 ) μm and ( 297.54 ±43.31 ) μm ( t = 5.961, P = 0. 000 ), and the average amplitude of PhNR were ( 80. 23±22.96 ) μV and (61.28 ±20. 16 ) μV ( t = 4. 438, P = 0. 001 ) before and after the intravitreal injection of TA, respectively,showing significant differences. No significant correlation was found between PhNR amplitude and retinal thickness of the macular area both before and after the administration of TA ( before: r = 0. 587, P = 0. 035; after:r=-0. 011 ,P = 0. 971 ). Conclusion PhNR can be used for evaluating the status of inner retina after intravitreal injection of TA for macular edema of CRVO.
