Objective To study the the effectiveness of Entecavir on serum transforming growth factor-β1 (TGF-β1) in patients with decompensated cirrhosis .Methods Eighty patients with decompensated cirrhosis were randomly divided into two groups ,the control group(n=40 cases) and the observation group (n=40 cases).The pa-tients in the control group were treated through the conventional treatmeat ,while the patients in the observation group were treated through the conventional treatment plus entecavir .They were treated for 24 weeks.Liver function,HBV DNA and serum TGF-β1 were detected.Results ALT,Tbil and ALB were improved after treatment in both groups (t=6.724,13.306,3.064,4.172,2.924,3.172,all P<0.05).They were more significantly improved in the obser-vation group than that in the control group (t=2.469,2.160,3.064,all P<0.05).HBV-DNA negative rate in the observation group was higher these in the control group (χ2 =4.82,P<0.05).Serum TGF-β1 in both groups were decreased after treatment(t=6.842,8.062,all P<0.01).There was a significant difference between two groups (t=3.178,P<0.05).Conclusion Entecavir can decrease serum TGF-β1 in patients with decompensated cirrhosis .

Objective To evaluate the expressions and roles of survivin (SVV), bcl-2 and proliferating cell nuclear antigen(PCNA) in cutaneous squamous cell carcinoma (SCC). Methods The expressions of SVV, bcl-2 and PCNA were investigated by SP immunohistochemistry technique in 82 cases of SCC and 18 normal skin samples. Results There were 79.3% of SCC patients with the expression of SVV (P

OBJECTIVE:To further exploit the active components from Loquat leaf and its gruffs.METHODS:The chief components in loquat leaf and its gruffs were extracted by ultrasound extraction and Soxhlet extraction,respectively,the sepa?ration of ursolic acid and other constituents was performed by HPLC,and the relative amounts of which were determined and compared.RESULTS:Soxhlet extraction is superior to ultrasound extraction in the extraction of loquat leaf and8components in gruffs.Under the same extraction method,the content of ursolic acid in loquat leaves is equivalent to that of gruffs.Besides,the contents of6components in gruffs were above those in loquat leaves.CONCLUSION:The essential component-triterpenic acid in loquat leaves suffered no loss after extraction with water,the active components in gruffs can be further exploited.

The mammalian target of rapamycin (mTOR) disorders have a close relationship with autoimmune disease,tuberous sclerosis (TfSC),cancer,obesity and senescence.mTOR inhibitors are wildly used in pediatric renal transplantation and TSC.Growth is an important indicator of children health and safety evaluation of pediatric drugs must include impact on growth.No evidence showed mTOR inhibitors had side effect on growth in children.

OBJECTIVE To compare the detection rates of Ureaplasma urealyticum(Uu),by 4 kinds rits and find out the best one.METHODS Using four kinds of mycoplasma detection kits,namely are French mycoplasmaIST2,Zhuhai Livzon′s ICS,Dark horse′s IES and Shanghai Its Prachanda,under the same conditions,the mycoplasma of the Clinical specimens for 260 cases were tested.RESULTS The detection rate of mycoplasma(Uu) for 48 hours by four kinds of brands kits about mycoplasma liquid culture was as follows 45.4% for French MycoplasmaIST2,36.2% for Zhuhai Livzon′s ICS,37.7% for Dark horse′s IES and 36.8% for Shanghai Its prachanda.The results of susceptibility test: the reagent of IST2 had.the lowest resistance to josamycin,doxycycline,clarithromycin,ofloxacin and azithromycin,and had the better results than the other three kinds of reagents.Mycoplasma reagents form different companies had significant differences in resistance rates to five kinds of antibiotics.CONCLUSIONS The results suggest that when we cultivate clinical mycoplasma should be careful to select of the mycoplasma liquid culture identification kit.

OBJECTIVE To investigate the clinical and etiology characteristics of nosocomial pneumonia. METHODS Patients with nosocomial pneumonia from Jan 2003 to Nov 2003 were chosen to be analyzed. RESULTS There were 241 patients with nosocomial pneumonia,the incidence rate of the nosocomial pneumonia in nosocomial infection patients was 41.77%,and the incidence rate of males was much higher than females(1.87∶1),and it was 43.15% in old person among patients with nosocomial pneumonia which was much higher than others,58.72% patients began to have the symptoms in the first 20 days from the day they accessed the hospital,the incidence rate of patients who had been treated by one antibiotic or two antibiotics combination,Immunosuppressors or glucocorticoids drugs were all higher than 50%,the incidence rate of patients who treated by radiotherapy,chemotherapy,thorax-abdomen operations,tracheotomy and ventilator were also quite high,the main pathogens were Gram-negative bacilli(63.95%). CONCLUSIONS We should make heavier prevention and treatment measures in front of target population and their high risk factors and the related rings,so that we can get the real effects.

Objective To explore the value of multi-slice spiral CT (MSCT) with three dimensional (3D) postprocessing for assessing the lung volume and compare it with pulmonary function test (PFT). Methods In 60 cases, there were 34 healthy controls and 26 patients with emphysema. CT scan and PFT were performed within 3 d in all case. The total lung was respectively scanned at the end of full inspiration and full expiration, using GE Lightspeed 16 slices spiral CT. The total lung volumes and voxel index (VI) at threshold range of -1023 Hu to -900 Hu were measured by pulmonary quantitative software of AW4.2 workstation. Results The full expiration volume(Vex) significantly correlated with residual volume(RV) (r=0.908) as well as the full inspiration volume (Vin) with total lung capacity (TLC) (r=0.897). The value of (Vin-Vex) well correlated with forced vital capacity(FVC), as well as Vex/Vin with RV/TLC, VI Ain with TLC, VI Aex with RV. Conclusion Significant correlation of lung volume accessed by MSCT with 3D technique with PFT is useful for assessing the pulmonary function.

Statin therapy has been shown to play a fundamental role in the treatment of coronary heart disease.Some studies have identified associations between genetic variants and response or toxicity in statin treatment.This review summarizes current knowledge of the pharmacogenomics of statin therapy in order to help to select the best individually adapted statin treatment for patients.

AIM: To establish a HSP90 highly expressing cell line and study the effect of high level of HSP90 on cell stress response. METHODS: The recombined plasimid pSmycHSP, which contains the full length DNA coding for human HSP90?, was introduced into mouse fibroblast cell line NIH-3T3 by electroporation after being subcloned, purified and identified by limited enzyme digestion. Screened by G418, the positive clones were selected and identified by immunofluorescence, immunocytochemistry and Western-blotting. NIH-3T3 cells transfected with empty plasmid served as control, hyperthermia(44 ℃, 20 min, 40 min)was used to simulate oxidative stress. The activity of lactate dehydrogenase (LDH) in supernatant and damage of DNA were detected by automatic biochemistry analyzer and flow cytometer separately to analyze the effect of high-level HSP90 on cell membrane and DNA injuries under stress condition. RESULTS: The rising level of HSP90 was shown by immunofluorescence, immunocytochemistry and Western-blotting in HSP90 overexpressing cell line. There was no difference in the leakage of LDH between HSP90 overexpressing cell line and control, but the damage of DNA was more severe at 44 ℃for 20 min in HSP90 overexpressing cell line than control. Compared with control, the above indices were relieved at 44 ℃ for 40 min in HSP90 overexpressing cell line. CONCLUSION: The NIH-3T3 derived cell line, which stably expressed high level of HSP90, was established. The effect of high-level HSP90 on cells is complex at different intensity of stress, and the protection may be shown at more severe stress circumstance.
