Objective To investigate the relationship between the serum ghrelin level and β-cell function after treatment of patients with newly diagnosed type 2 diabetes mellitus.Methods 34 patients with newly diagnosed type 2 diabetes mellitus were divided into three groups of pre-treatment(DM0),two weeks after treatment(DM1)and six months after treatment(DM2).Intravenous glucose tolerance tests(IVGTT)were performed and blood glucose,HbA1C,ghrelin,insulin were measured during the study.Insulin sensitivity was assessed by homeostasis model assessment(HOMA).Results(1)Compared with DM0 group,beta-cell function and the mean AUC of insulin were dramatically improved in groups of DM1 and DM2(all P<0.05).(2)Compared with DM1 and DM2,ghrelin levels and the mean AUC of ghrelin in DM0 groups were lower(all P<0.05).(3)Only positive correlation between ghrelin and HOMA-β(r=0.446,P<0.05),and negative correlations of ghrelin with glucose(r=-0.274,P<0.05),insulin(r=-0.35,P<0.05)and BMI(r=-0.276,P<0.05)were found after six months of treatment.Conclusions Ghrelin might play an important role in the pathogenesis and progress of type 2 diabetes mellitus.

Objective To explore the association of serum uric acid (UA) with metabolic syndrome (MS) and its components.Methods A total of 1 512 inhabitants aged 20 years old and above in Zhaiji community of Guiyang urban areas were investigated from November 2009 to February 2010 by adopting stratified cluster sampling method (634 males and 878 females).All subjects were asked to fulfill the questionnaires and to measure the height,weight,waist circumstance (WC),and blood pressure ; and to undertake oral glucose tolerance test.Venous blood samples were drawn to measure UA,fasting plasma glucose,2 h postprandial plasma glucose,triglyceride (TG),total cholesterol,high density lipoprotein cholesterol,low density lipoprotein cholesterol,and fasting insulin.Results (1) Age,body mass index (BMI),WC,TG,and blood pressure,and homeostasis model assessment of insulin resistance (HOMA-IR) increased with UA (all P＜0.05).(2) UA was positively associated with the risk of MS (P＜ 0.05).After adjusting for age,sex,BMI,waist-to-hip ratio (WHR),and HOMA-IR,the risk of MS in individuals with the highest uric acid quartiles was significantly increased compared to those with the lowest quartile (OR =2.86,95 ％ CI 1.70-4.84,P＜0.05),and this finding was especially evident in females (OR=2.80,95％ CI 1.51-5.17,P＜0.05).(3) UA was strongly related to WC (OR =1.76,95％ CI0.95-3.27,P＜0.05),blood pressure (OR =1.66,95 ％ CI 1.13-2.43,P＜0.05),and TG (OR =2.80,95％ CI 1.97-3.96,P＜0.05) after adjustment for age,sex,BMI,WHR,and HOMA-IR.Conclusion The prevalence of MS increased with UA.Higher UA level may be an independent risk factor for MS.

Objective To explore the relationship between serum thyroid-stimulating hormone ( TSH) and dyslipidemia. Methods A total of 1 512 inhabitants in Zhaiji community of Guiyang urban areas were investigated from November 2009 to February 2010 by adopting stratified cluster sampling method, and 1 428 subjects were included in the present study. All subjects were asked to fulfill the questionnaires and to pass a physical examination. The vein blood samples were taken for determination of serum TSH, fasting plasma glucose (FPG), insulin, as well as blood lipid levels. Results Triglyceride ( TG ) , total cholesterol, high density lipoprotein cholesterol, and low density lipoprotein cholesterol levels were significantly increased in woman with subclinical hypothyroidism(SCH) compared to those with euthyroid(all P<0. 05). However, there was no significant difference in man between two groups(P>0. 05). The incidences of hypertriglyceridemia in the euthyroid group from quartile 1 toquartile4ofTSHwere33.3%,35.5%,39.7%,and44.0% respectively(P<0.05). SerumTGlevelwas increased with TSH in woman and total subjects after adjustment for age, sex, body mass index ( BMI) , waist-hip ratio (WHR), and homeostasis model assessment for insulin resistance index(HOMA-IR, P<0. 05). Serum TSH levels in the total sample were positively associated with TG after adjustment for age, sex, BMI, WHR, and HOMA-IR (β=0. 088,P<0. 05). Conclusion Higher serum TSH levels even within normal range seems to be a risk factor of dyslipidemia.

A total of 1512 adult inhabitants were randomly recruited in Zhaiji district of Guiyang city in September2009.The levels of triglyceride (TG),systolic blood pressure,diastolic blood pressure,and the prevalences of abdominal obesity and hypertension increased significantly in the subclinical hypothyroidism group conpared to the euthyroid group (P＜0.05).The prevalences of high TG,low high density lipoprotein-cholesterol,and metabolic syndrome (MS) in the subgroup Ⅳ were higher than the subgroup Ⅰ (P＜0.05).Correlation analysis revealed that TSH was positively related to TG (P＜0.05).Logistic regression demonstrated that TSH was a risk factor for MS.Either in the euthyroid or total subjects serum TSH levels in the MS group were significantly higher than those in non-MS group(P＜0.05).

Objective To investigate the effects of ginsenoside Rg3 on growth and apoptosis of gastric cancer cell line MKN-45 and SGC-7901 in vitro. Methods MKN-45 and SGC-7901 cells at logarithmic growth phase were obtained, and were cultured with ginsenoside Rg3 of different concentrations (20, 30, 40, 50 μg/mL) for 24, 48 h or 24, 48 and 72 h. Cells cultured without ginsenoside Rg3 were served as controls. The inhibition rates of ginsenoside Rg3 on MKN-45 and SGC-7901 cells were detected by MTT assay, apoptosis rate of SGC-7901 cells was determined by Annexin V/PI double staining flow cytometry, cell cycles of SGC-7901 cells were analysed by flow cytometry, and morphological changes of SGC-7901 cells in 50 μg/mL ginsenoside Rg3 treatment group were observed by transmission electron microscopy. Results The inhibition rates on MKN-45 and SGC-7901 cells in each ginsenoside Rg3 treatment group were significantly higher than those in control group (P < 0.05), and the inhibition rates increased with the concentrations of ginsenoside Rg3 and time of culture ( P < 0.05). Compared with control group, the apoptosis rates of SGC-7901 cells and percentages of cells in G_1/G_1 cell cycle in each ginsenoside Rg3 treatment group were significantly increased in a concentration and time dependent manner. Typical morphology of SGC-7901 cell apoptosis was observed by transmission electron microscopy in 50 μg/mL ginsenoside Rg3 treatment group. Conclusion Ginsenoside Rg3 has significant inhibition effect on gastric cancer cell lines in vitro with a concentration and time dependent manner, the mechanism of which may involve the induction of gastric cell line apoptosis.

Objective To investigate the change of prevalence of autoimmune thyroiditis in Guiyang city after adjustment of salt iodine content, and to study the link between the level of iodine intake and the development of autoimmune thyroiditis. Methods With cluster sampling method, a cross-sectional study was conducted among adults aged 20 years old or above in Guiyang in 2009 (before adjustment, n=1 509) and 2015 (after adjustment, n=1 368). After an overnight fasting, thyroid stimulating hormone (TSH), thyroid peroxidase antibody (TPOAb), and thyroglobulin antibody (TgAb) were measured. The serum FT4 and FT3 were determined for the subjects with abnormal TSH. Meanwhile, urine iodine levels of children aged 8-10 years old in the same community were measured after an overnight fasting in these two studies. Results In 2009, the median level of 8-10 years old children′s urinary iodine was 228.7 μg/L. The prevalence of positive TPOAb, positive TgAb, and thyroid autoantibodies (TAAs) were 14.38%, 13.59%, 18.89%, the standardized prevalence were 14.35%, 13.59%, 18.89% respectively. The prevalence of subclinical hypothyroidism, autoimmune thyroiditis were 14.12% and 4.44%, with the standardized prevalence were 14.12%, 4.42% respectively. In 2015, the median urinary iodine level of 8-10 years old children was 190.1 μg/L, the prevalence of positive TPOAb, positive TgAb, and TAAs were 8.77%, 7.82%, 11.77%, the standardized prevalence were 8.98%, 7.97%, 12.13% respectively; the prevalence of subclinical hypothyroidism, autoimmune thyroiditis were 22.89%, 2.92%, with the standardized prevalences of 23.19%, 3.02% respectively. Conclusion After adjustment of salt iodine content, the iodine nutrition in Guiyang is at the appropriate level, and the values of TPOAb, TgAb, TAA, and autoimmune thyroiditis in adults of Guiyang city were all decreased.

Objective To explore the relationship between metabolic syndrome(MS) and glomerular filtration rate(GFR).Methods A total of 10 140 adults aged 40 years and older inhabitants in Zhaiji community of Guiyang urban areas were investigated from May 2010 to August 2010 by adopting stratified cluster sampling method.The venous blood sample was drawn for the measurements of serum creatinine(Cr), fasting plasma glucose(FPG), OGTT 2hPG, fasting insulin, triglyceride(TG), total cholesterol(TC), high-density lipoprotein-cholesterol(HDL-C), low-density lipoprotein-cholesterol(LDL-C), and fasting plasma insulin.The definition of MS in our study was modeled after the Adult Treatment Panel Ⅲ(ATP-Ⅲ).Decreased GFR was defined as an estimated GFR<60 ml·min-1·(1.73 m2)-1.Results The prevalence of GFR less than 60 ml·min-1·(1.73 m2)-1 were 3.0% and 1.2% in participants with and without MS, respectively.The multivariate-adjusted odds ratios[95% confidence interval(CI)] of MS, which were independently associated with decreased GFR, were with elevated blood pressure, higher TG, lower HDL-C, and elevated FPG, their statistically odds ratios were 1.78, 2.96, 1.06, and 1.22, respectively.The prevalence of GFR decreased with the increase of MS components by 0.56%, 1.10%, 1.50%, 2.87%, 3.23%, and the odds ratios were 1.00, 1.57, 1.93, 3.07, and 2.89, respectively.Conclusion With the increase of MS components the risk of GFR decline increased.The occurrence of chronic renal dysfunction(CKD) might integrate multiple different risk factors of MS.

OBJECTIVETo explore the therapeutic effects of internal fixation with Herbert screws for the treatment of Pipkin type I and type II femoral head fractures.

METHODSFrom January 2008 to December 2012, 23 patients with Pipkin type I and type II femoral head fractures were treated with open reduction and internal fixation by Herbert screws through Kocher-Langenbeck approach. Twenty-three patients (aged 18 to 52 years with a mean of 35.5 years, including 18 males and 5 females patients, 8 left hips and 15 right hips) with femoral head fractures and posterior hip dislocation. The fracture was classified according to Pipkin classification based on the radiographic findings, 5 patients had type I and 18 had type II fractures. The duration time from admission to the operation ranged from 6 to 72 h (averaged 32 h). The clinical and radiographic outcomes of the patients were measured using Thompson-Epstein scoring scale. The Harris hip score(HHS) was used to evaluate and compare hip functions at the latest follow-up between affected and healthy sides.

RESULTSAll the patients were followed up, and the duration ranged from 20 to 48 months (averaged 30 months). According to Thompson-Epstein system, 12 patients got an excellent result, 6 good, 4 fair and 1 poor. The average HHS at the finial follow-up was 87.80 ± 8.46 (ranged from 66 to 95), which is similar to that in the healthy side 90.10 ± 6.35 (ranged from 72 to 98) (t = 1.044, P = 0.302). The complications such as deep infection, and deep vein thrombosis were not found. At the 3rd year during follow-up,4 patients had avascular necrosis of femoral head. At the 1st year of follow-up, 1 patient had hip pain after walking,screws loosening and shift after trauma,and serious complications of traumatic arthritis. All the 5 patients were treated with total hip arthroplasties.

CONCLUSIONThe treatment of internal fixation with Herbert screws through the Kocher-Langenbeck approach is effective for Pipkin type I and type II femoral head fracture. The method is reliable and valuable for recommendation. However, such fracture may have avascular necrosis of femoral head and complication of traumatic arthritis, which should be observed carefully in clinic with preparation of the prevention and treatment measures.
