[Objective] To discuss the importance of causa morbi and early diagnosis and treatment on the prognosis and lapsing of hypoglycemia.[Method] Select 33 cases and make detailed enquiry and analysis to their causa morbi, occurrence time length and complications, supplement timely glucose injection, if necessary, administer glucocorticoid for treatment; observe the patients ’clinical symptoms relieve, and compare the usage of glucose and glucocorticoid, the in-hospital period and relative indexes of prognosis and lapsing.[Result] In the group, 28 cases are drug-induced hypoglycemia, occupying 84.85%;30 cases have the period less than 6h from occurrence to diagnosis, among which, 1 had cerebrovascular accident and consulted with neurology department, relieved with treatment, but with sequela of hemiplegia; 1 case had too long time of dizziness before coming to hospital(>24h), couldn ’t be better over treatment, the relatives gave up the treatment and went out of hospital; 1 was tested of islet celltumor and transferred to upper hospital, without recurring hypoglycemia being fol owed up.[Conclusion] Drug-induced hypoglycemia is the main reason for hypoglycemia, with much harm;early diagnosis, remov-ing causa morbi and active rescuing wil have good prognosis.

Liver diseases post great threats to human public health globally.Lacking of appropriate small animal models largely impeded the translational studies on human liver diseases, especially on viral hepatitis and related cirrhosis, hepatocellular carcinoma, etc.By human hepatocyte transplantation, the liver-humanized mice have significantly contribu-ted to the researches of human liver diseases.This review summarizes the currently widely used and representative human-ized mouse models, including uPA, FAH, TK-NOG, AFC8 mice and their applications in studies of human liver diseases.

Objective To investigate the therapeutic effect and its mechanism of pathogenicity of streptozotocin diseased rats treated by the mixture of kelp extract, wolfberry, and Chinese yam. Methods Streptozotocin-diabetic rat model were taken the mixture of kelp extract, wolfberry and Chinese yam with the ratio of 1:1:1 by intragastric administration. positive control group was fed metformin of 83.5mg/kg, the control group and the model group were given the same amount of distilled water. The safety of high dose (1500 mg) of the mixture therapy for the normal rat were evaluated, their blood glucose levels, glucose tolerance, body weight and insulin levels were observed and its possible mechanism were analyzed. Results Compared with the model group, the disease diabetic rats of the administered group (250mg/kg,500mg/kg,1500mg/kg) were significantly alleviated. First of all, coat color was more shiny, the behavior were more physical agility. Followed by the decrease of blood glucose levels and AUC, and body weight and insulin levels were elevated. In cell experiments, the number of islet cells was increased in the administered group by the mixture in a dose-dependent manner. Conclusion The mixture of kelp extract, wolfberry, and Chinese yam had obvious hypoglycemic effect. The hypoglycemic activity of the mixture may be attributed to increase insulin secretion through inhibit apoptosis of islet β-cells.

Objective To evaluate the relationship between ischemic cerebrovascular desease(ICVD) and carotid atherosclerosis and its risk factors.Methods 186 cases with ICVD and 194 cases without cerebrovascular disease or healthy people(control group) were enrolled in this study.Carotid ultrasonagraphy was performed in the two groups and blood biochemical indexes were detected in the meanwhile.The data were compared between the two groups.Results Higher age(69?7years) and higher prevalence of hypertension(66.1%),diabets mellitus(53.4%) and metabolic syndrome(44.6%) were found in ICVD group than in control groups [(61?5)years,48.8%,15.2%,12.9%](all(P

The lipoprotein-associated phospholipase A2 (Lp-PLA2), a subtype of the phospholipase A2 superfamily, is produced primarily by macrophages and lymphocytes. Lp-PLA2specifically hydrolyzes oxidized phospholipids on oxidized low-density lipoprotein particles,resulting in production of lysophosphatidylcholine and oxidized fatty acids. Lp-PLA2 is expressed in atherosclerotic plaques and in macrophages within a fibrous cap of unstable plaque.Studies haw shown that the plasma Lp-PLA2 activity increases significantly in patients with ischemic stroke, and Lp-PLA2 may become an independent risk factor for predicting ischemic cerebrovascular events. The selective Lp-PLA2 inhibitor can reduce the inflammatory response,enhance the stability of plaques, and inhibit the formation of atherosclerotic plaques, and may become a new class of drugs for preventing the formation of atherosclerotic plaques.

With the body senescing,the endocrine function decreased.In the recent more than ten years,a relationship between pituitary-thyroid axis dysfunction and senile psychosis has attracted increasing attention.Thyroxin is thought to be closely related with the cognitive dysfunction and senile dementia.

The most important cause of late mortality after lung transplantation is obliterative bronchiolitis ( OB) . It is clear that a good animal model is indispensable to further unravel and clarify the pathogenesis of bronchiolitis obliterans syndrome ( BOS) .Many animal models have been developed to study BOS, however, so far, none of these models truly mimics the human condition.In recent years mouse models of orthotopic lung transplantation have been established, which provide potential possibilities for further studies of OB/BOS after lung transplantation.The aim of this article was to review the pros and cons of those animal models, and discuss the possible approaches to establish animal models of chronic rejec-tion after lung transplantation.

OBJECTIVE:To provide reference for prevention of nosocomial drug-induced liver injury(DILI),early diagnosis of DILI and appropriate disposal of DILI.METHODS:4 975 medical records were randomly collected from a grade three class A hospital during 2008～2009.The incidence of DILI,hospitalization costs,extended time of hospital stay and prevention of DILI were analyzed retrospectively and economic evaluation was carried out.RESULTS:DILI occurred in 63 cases with the incidence rate of 1.27%.Among these cases,10 cases(15.87%) were preventable.For each DILI,average increased medical cost was 3 220.26 yuan and average extended time of hospital stay was 4.38 d.For the preventable DILI,the average increased medical cost was 6 239.85 yuan,and average extended time of stay was 8.30 d.The top 3 drugs which caused liver injury were anti-infective drugs(including antitubercular agent,41.27%),antineoplastic agents(28.57%) and cardiovascular drugs(7.94%).Types of DILI were as follows:live cell injury accounted for 65.08%,cholestasis accounted for 25.40%,and mixed type accounted for 9.52%.CONCLUSION:DILI is characterized with high incidence rate among patients and high medical cost.Some of DILI cases are preventable.Therefore,There is advantage both in clinical and economic aspects to reduce the incidence rate of preventable DILI by emphasizing rational use of drugs.

Objective To summarize the pathological features of nonalcoholic fatty liver disease(NAFLD)in China based on a histological scoring system for NAFLD designed by the Pathology Committee of NASH Clinical Research Network(NASH-CRN).Methods The specimens of liver needle biopsy from 130 patients with NAFLD were examined with light microscopy after haematoxylin eosin,reticular fiber,and Masson trichrome staining.Immunohistochemistry staining of the sections,combined with clinical data,was used to exclude non-NAFLD cases.Results Hepatic steatosis,lobular inflammation,hepatocyte ballooning and fibrosis existed extensively in 130 cases NAFLD liver tissues.Furthermore,macrovesicular steatosis predominantly located in acinar zone 3 was the main pathological feature of NAFLD,and lobular inflammation was usually mild.Hepatocyte ballooning was observed in 94.6 percent of 130 cases.Mild perisinusoidal fibrosis and periportal fibrosis were often observed in stage 1.According to the statistic analysis,hepatic steatosis was positively correlated with lobular inflammation,hepatocyte ballooning and fibrosis(r=0.587,0.488,0.374,respectively;all P value

Objective To investigate changes and the clinical significance of serum 25-Hydroxyvitamin D level in patients of Xinjiang Uygur and Han nationalities with mild cognitive impairment.Methods On the base of early stage of epidemiological survey of Xinjiang Uygur and Han population over 60 years old,adopting multi-stage stratified random cluster sampling method and referencing DSM-Ⅳ,206 cases of MCI patients (study group)were selected and 412 healthy elderly subjects (control) matching for age,nationality and gender were recruited for case-control study.The serum level of 25(OH) D was measured by enzyme-linked immunosorbent assay (ELISA).Results The serum level of 25(OH)D was significantly lower in MCI group of two nationalities (7.89±0.29 μg/L) than in normal control group [(8.65± 0.21) μg/ml,P＜0.05].The serum level of 25(OH)D was (8.41±0.34) μg/L in Han group,and (8.37±0.32)μg/L in Uygur group,with no significant difference (P＞0.05).The 25 (OH)D level was significantly lower in female[(8.23± 0.32) μg/L] than in male [(8.70±0.42) μg/L,P＜0.05].The serum level of 25(OH)D was lower in female MCI group [(7.56±0.34) μg/L] than in female control group [(8.41 ±0.31)μg/L],with significant difference (P＜0.05).While there was no significant difference between male MCI and male control group (P＞0.05).Multivariate Cox regression analysis showed that the risk factors of MCI might include low serum 25 (OH) D levels (OR =1.163,95 ％ CI:0.978-1.447),a decreased physical labor (OR=1.420,95％ CI:1.10-1.860),low education degree (OR =1.504,95％ CI:1.129-2.130),celibacy (OR=1.293,95％CI:0.845-1.440),hypertension (OR=1.954,95％CI:1.342-2.670),diabetes (OR =1.320,95％ CI:1.145-1.710),smoking history (OR =1.350,95％ CI:1.101-2.293),high BMI (OR=1.329,95％CI:1.068-1.781).Conclusions The serum 25(OH)D level is lower in MCI patients in Xinjiang Uygur and Han populations than in normal people,but there is no significant difference.The 25 (OH)D deficiency is associated with increased odds for cognitive impairment in the elderly Xinjiang population,which is more obvious in the female.The occurrence and development of MCI is affected by multiple risk factors.
