Objective To investigate the prevalence and distribution of pre-diabetes and diabetes mellitus in Han population aged over 60 years in Urumqi. Methods The physical examination and 75 g oral glucose tolerance test (OGTT) were performed in 2210 people, including 1231 elderly people aged over 60 years (old age group) and 951 people aged 40-59 years (middle age group). The diagnosis of diabetes mellitus was established according to WHO criteria in 1999. Results In Han ethnic people, the prevalence rates of diabetes mellitus and pre-diabetes were 32.2% and 29.0% respectively in old age group, and were significantly higher than in middle age group ( 12.3% and 20.9%,x2= 192.62, P<0.05). The prevalence rates of impaired glucose tolerance (IGT) were higher in old age group than in middle age people (21.6% vs. 13.9%, x2 = 20.97, P<0.05), but there was no significant difference in the prevalence rate of impaired fasting glucose (IFG) between the two groups. The prevalence rate of metabolism syndrome (MS) was higher in old age group than in middle age group (52.2% vs. 33.7%, x2 =73.77, P<0.05). The multivariable analysis showed that hypertriglyceridemia, hypertension, family history of diabetes mellitus were risk factors for development of diabetes mellitus in elderly Han population (x2 =44.34, P<0.05). Conclusions The prevalence rates of diabetes and pre-diabetes are considerably high in the current state. It should be strengthened to prevent and treat diabetes mellitus and pre-diabetes in Urumqi Han population,especially in residents aged over 60 years.

OBJECTIVETo evaluate the clinical effect of Dusuqing (DSQ) in treating senile bacterial pneumonia and to explore its possible mechanism.
METHODSPatients were randomly divided into two groups, the treated group treated with conventional western therapy (CWT) and the combined treated group treated with CWT plus DSQ respectively. The changes of serum cytokines, interleukin-2 (IL-2) and tumor necrosis factor-alpha (TNF-alpha), before and after treatment were observed.
RESULTSIn the 33 patients of the combined treated group, the total effective rate being 93.9%. While in the 31 patients of treated group, the total effective rate being 83.9%. The difference of the total effective rate between the two groups was significant (P < 0.05). The scores of principal symptoms, secondary symptoms and total scores were all obviously lowered in both groups, particularly in the combined treated group. The peripheral blood IL-2 level was lower and TNF-alpha higher in senile patients than those in healthy aged subjects respectively. All the two parameters approached normal level in the combined treated group but with insignificant change in the CWT treated group.
CONCLUSIONDSQ showed obvious effect in treating senile bacterial pneumonia. The mechanism might be related with the lowering of inflammatory cytokines such as oversecreted TNF-alpha, as well as the improvement of immune function (elevation of IL-2) of organism.

Objective To explore the best time point for the ipsilateral hepatocellular apoptosis and the contralateraI hepatic hypertrophy after selective portal vein embolization(SPVE)in rabbit.Methods In a randomized study design,forty rabbits were divided into 5 groups with 8 rabbits per-group,including one as the control and the other 4 were treated with SPVE during open surgery.The rabbits were killed postoperatively,in 3,7,14,21 days respectively after the embolization.The hepatic lobes volume,the ipsilateral hepatocellular necrosis rates and apoptosis index,and liver functions were determined as well. Results In the treatment groups,the average amount of the right liver volumes decreased from 46.4 cm~3 preoperatively to 46.0,44.4,42.0,39.7 cm~3 in groups of 3,7,14,21 days postoperatively;meanwhile,the left liver volumes increased from 54.0 cm~3 preoperatively to 54.5,56.3,61.7,63.9 cm~3 respectively during 3, 7,14,21 days after the procedures.The rates of future remaining live volumes(FRLV)increased from 53.8% preoperatively to 54.2%,55.9%,59.0%,61.0% at 3,7,14,21 days postoperatively.The apoptosis indexes of hepatocells from group A to E were 8.1%,12.2%,19.4%,20.1%,14.2% respectively.Conclusions SPVE leads to atrophy of the ipsilateral hepatic lobe and hypertrophy of contralateral lobe,indicating that hepatocytes undergone apoptosis,rather than necrosis.The time point is 7 to 14 days.

This study is to evaluate the therapeutic effect of fibroblast growth factor 21 (FGF21) on NAFLD in MSG-IR mice and to provide mechanism insights into its therapeutic effect. The MSG-IR mice with insulin resistance were treated with high dose (0.1 micromol.kg-1d-1) and low dose (0.025 micromol.kg-1d-1) of FGF21 once a day for 5 weeks. Body weight was measured weekly. At the end of the experiment, serum lipids, insulin and aminotransferases were measured. Hepatic steatosis was observed. The expression of key genes regulating energy metabolism were detected by real-time PCR. The results showed that after 5 weeks treatment, both doses of FGF21 reduced body weight (P<0.01), corrected dyslipidemia (P<0.01), reversed steatosis and restored the liver morphology in the MSG model mice and significantly ameliorated insulin resistance. Additionally, real-time PCR showed that FGF21 significantly reduced transcription levels of fat synthetic genes, decreased fat synthesis and promoted lipolysis and energy metabolism by up-regulating key genes of lipolysis, thereby liver fat accumulation was reduced and liver function was restored to normal levels. In conclusion, FGF21 significantly reduces body weight of the MSG-IR mice, ameliorates insulin resistance, reverses hepatic steatosis. These findings provide a theoretical support for clinical application of FGF21 as a novel therapeutics for treatment of NAFLD.

OBJECTIVETo study the impacts of tetramethylpyrazine (TMP) intervention on hemorheology and blood coagulation before and after free skin flap transplantation, in order to provide new clues of applying Chinese drugs for activating blood circulation and removing stasis in microsurgery.
METHODSSixty patients undergoing free skin flap transplantation were randomly and equally assigned to two groups, the treatment group administered with tetramethylpyrazine, the control group with low molecular dextran, both were treated for 7 days. The survival rate of transplanted flap, hemorrheologic parameters and four blood coagulation associated indices (prothrombin time, thrombin time, activated prothrombin time and fibrinogen) were detected before and after treatment.
RESULTSComparisons of clinical efficacy and hemorrheologic indices showed no significant difference between the two groups (P > 0.05), but TMP showed less impacts on the four blood coagulation associated indices at the 24, 48 and 72 h after operation (P < 0.05).
CONCLUSIONTMP could prevent blood vessel crisis after free skin flap transplantation, so it is valuable in microsurgical clinical application.

Thermogravimetry (TG), TG-MS, Fourier transform infrared spectroscopy (FTIR), scanning electron microscope (SEM)-energy dispersive spectrometer(EDS) were adopted to investigate the pyrolysis characteristics of calamina. According to the findings of the qualitative and quantitative studies on the changes in the content of relevant elements, the whole shape, the functional groups, and the volatile components of calamina before and after being pyrolyzed, the 200-360, 580-750 degrees C were two sensitive temperature ranges related to the changes in effective component during calamina processing. Thermal weight loss was observed for ZnCO3, Zn(OH)2 and ZnCO3-2Zn(OH)2-H2O under 200-360 degrees C and for CaCO3 under 580-750 degrees C. The results of studies on chemical reaction kinetics showed good linear relations. This experiment integrated relevant methods and theories of physical chemistry and science of traditional Chinese medicine processing, and interpretes calamina processing techniques and mechanism, in order to provide a good example for modem studies on other traditional Chinese medicine processing.
