Objective To evaluate the prognostic value of dynamic delta model of end stage liver disease(MELD)in patients with decompensated liver cirrhosis.Methods Ninty-seven patients with decompensated liver cirrhosis were enrolled in the study and followed for 1 year followed up.Child-Turcotte- Pugh(CTP)score and MELD score were calculated twice for each patient on the first day of admission and one month later.The difference between two MELD scores represented the delta MELD.The predictive value related with delta MELD,MELD and CTP scores was determined by the area under receiver operating characteristic(ROC)curve.Results Ten patients died within 3 months,whose delta MELD(3.23?2.77) were higher than those of survivors(0.15?0.39)(P

0.05). The relative bioavailability of tested capsules to reference tablets was (99.3?13.1)% Conclusion Both formulations are of bioequivalence.

Objective To investigate the relation between the characteristics of body fat distribution and the cardiovascular risk factors in some patients with type 2 diabetes mellitus (T2DM)in Xinjiang region.Methods The percentage of body fat (PBF)and visceral fat area(VA)were determined in 155 cases of T2DM by using the Inbody 720 body composition analyzer.At the same time triglycerides(TG),total cholesterol(TC),high density lipoprotein(HDL-C),low density lipoprotein(LDL-C),blood pressure(BP), glycosylated hemoglobin HbA1c,body weight(W),body height,waist circumference ratio(WC)and hip circumference(HC)were also determined.The body mass index(BMI)and the waist to hip ratio was calculated.Results In both men and women,BMI in the subjects with visceral fat obesity(VFO)was higher than that with subcutaneous fat obesity(SFO).In males,TG in VFO was signif-icantly higher than that in SFO.PBF,TC and LDL-C in the female T2DM patients were significantly higher than those in the male T2DM patients.VA and PBF in the minority male patients were significantly higher than those in the Han nationality male patients (P <0.05).After correcting the age,course of disease and BMI,WHR in the female patients was positively correlated with DBP and PBF was positively correlated with LDL-C.In the male patients,there were correlations between BMI with SBP,between VA with DBP,and between VA with PBF and HDL-C;in the female patients,there were correlations between BMI with SBP and be-tween WHR with DBP.Conclusion The body fat distribution in the patients with T2DM in Xinjiang region is dominated by VFO. The cardiovascular risk factors are not only associated with the increase of body fat content,but more closely associated with VFO, moreover the differences in genders and nationalities exist.

BACKGROUND:L-type calcium channels, as a kind of voltage-dependent calcium channel, is the main way of extracellular calcium ions into the cell, and play an important role in maintaining cellmorphology and physiological activities, characterized by a large single-channel conductance, slow channel attenuation, and longer duration of channel opening. Previous studies showed that basic fibroblast growth factor can promote the proliferation of chondrocytes cultured in vitro.
OBJECTIVE:To explore the effect of the L-type calcium channels on regulating chondrocyte proliferation and differentiation in response to basic fibroblast growth factor with patch-clamp.
METHODS:The chondrocytes were harvested from the joints of 3-day-old New Zealand rabbits. The second passage of chondrocytes was divided into experimental group and control group. Chondrocytes were incubated in media containing 10μg/L basic fibroblast growth factor and media alone separately. The opening of L-type calcium channels under the action of basic fibroblast growth factor was detected by patch-clamp. The intracellular calcium concentration was detected with laser confocal microscopy in the chondrocytes after 2 weeks of culture with basic fibroblast growth factor. Chondrocyte proliferation was analyzed by cellTiter kit after 8 days of culture. Type Ⅱ col agen was assessed quantitatively by immunohistochemistrical staining after 10 days of culture.
RESULTS AND CONCLUSION:Basic fibroblast growth factor has an inhibitory effect on the opening of the L-type calcium channels, resulting in a decrease in intracellular free calcium concentration (P<0.01). cellnumber was higher after culture with basic fibroblast growth factor than that cultured under conventional condition (P<0.01), and staining area of type II col agen significantly increased (P<0.05). Results verified that basic fibroblast growth factor can maintain intracellular Ca2+concentration at a low level by inhibiting the opening of L-type calcium channels, which can promote the proliferation and differentiation of chondrocytes.

Objective To analyze the antimicrobial susceptibility of Mycoplasma isolates for rational antimicrobial therapy. Methods BioM?rieux IST kit was used for identification and susceptibility testing of Mycoplasma strains.Results Mycoplasma was positive in 49.5% of the specimens tested.Of the Mycoplasma detected,Ureaplasma urealyticum(Uu)alone accounted for 74.7%,Mycoplasma huminis(Mh)alone accounted for 18.1%,and Uu+Mh was identified in 7.2% of the patients.The results of antimicrobial susceptibility testing showed that the Mycoplasma isolates were most susceptible to doxycycline (98.1%).Ciprofloxacin was the least active (17.3%).Conclusions Doxyeycline,josamycin,and clarithromycin can be used in the treatment of urinary tract infections caused by Mycoplasma.

Bioimprinting is a new developed technique to improve the characteristics of enzymes.Bioimprinting by lauric acid was conducted to improve the esterification activity of lipase PS in sol-gel immobilization process with methyltrimethoxysila(MTMS) and tetramethoxysila(TMOS) as the precursors.Results generated by checking the esterification activity and scanning electron microscope showed that bioimprinting can enhance the specific activity and thermal stability of lipase PS.The bioimprinting system was optimized by orthogonal experiment,and the optimal condition for lipase bioimprinting is water/silane molar ration(R) 12,polyethylene glycol(PEG) 120?l,and lauric acid 0.15 mmol.Compared with the free enzyme and the non-imprinted enzymes,the specific activity of imprinted enzymes has been improved 44.3 fold and 2.4 fold,respectively.Imprinted lipase show better thermal stability,and the relative activity is 58% after incubated in 80 ℃ for 0.5 h,while no activity was detected for the free enzyme.

AIM: To probe into the genetic susceptibility of HLA-DRB1 alleles to esophageal neoplasm in Hubei Han Chinese. METHODS: HLA-DRB1 gene polymorphism in 42 patients with esophageal neoplasm and 136 normal control subjects was studied by PCR and sequence. RESULTS: Allele frequency of HLA-DRB1 *0901 allele was significantly higher in esophageal cancer patients than those in normal controls (0 2500 vs 0 1397,P =0 028; the odds ratio 2 053; etiologic fraction 0 1282).There were no association between the rested HLA-DRB1 alleles with patients. CONCLUSION: Individuals carrying HLA-DRB1 *0901 may be susceptible to esophagealo carcinoma, its nucleotide sepuence approachs to the corresponded allele sequence(exon 2)published in GenBank.

0.05).Conclusion The result suggests that T1 locus genetic polymorphism is weakly associated with asthma.

control group from the high to the low. When the typeⅢand type Ⅳglomerular function was changed (BUN and BCr in high value),the drainage quantity of the enzymes evidently increased.Conclusions Urine enzyme series can sensitively reflect the damage of renal tubules in early stage, even if BUN and BCr value is on the normal level , and the drainage quantity of these enzymes are changed more or less, which show that renal tubule damage exists. The value of BUN and BCr is positively correlated with the drainage quantity of these enzymes.the more urine enzymes are drained out, the more renal tubule function is involved, therefore, the more renal globe function is damaged.
