1.Determination of telomerase activity in exfoliated cells in urine for the diagnosis of bladder carcinoma
Chinese Journal of Laboratory Medicine 2001;0(04):-
Objective In order to find a more sensitive and specific noninvasive assay for the diagnosis of bladder carcinoma, the authors tested the exfoliated cells from patient′s voided urine for the presence of telomerase activity and evaluated its clinical significance.Methods PCR-ELISA assay was used to determine the presence of telomerase activity in voided urine samples from patients with bladder carcinoma, fhematuria of benign causes and from normal, healthy volunteers.Results Telomerase activity was detected in 14 of 18 tumor samples, while none of the hematuria samples and normal, healthy volunteers′ samples. Conclusions Telomerase activity could be detected in most urine samples of bladder carcinoma patients and it is more sensitive and specific than other assays, therefore, would be a good diagnostic marker.
2.Assessment of family environment of neurosis patients and the relativity analysis with the relapse
Chinese Journal of Primary Medicine and Pharmacy 2006;0(08):-
Objective To assess the family environment of neurosis patients and its affect to the prognosis. Methods The gender,knowledge,contact time for each week,yearly income,city/countryside and the factors of FES-CV were compared between the patients" family and normal family and the correction between the relapse and the family factors of the patients were analysed.Results Expressed emotion and intimacy of the patients' family were evidently lower than those of the normal family,but the factor of control the former was higher than that of the latter.Expressed emotion and intimacy were correlative with the relapse.Conclusion Family environment has the important influence on the maintenance and the relapse of the neurosis.

Objective To investigate the clinical effect by early mechanical ventilation and perfluorocarbons gasification inhala-tion on patients with severe acute pancreatitis (SAP) complicated with acute respiratory distress syndrome (ARDS) .Methods 34 cases of SAP and ARDS patients accepted early mechanical ventilation and vaporization of perfluorocarbon inhalation therapy (ob-servation group) ,and 34 patients received mechanical ventilation for early treatment alone (control group) ,The efficacy ,oxygenation index(PaO2/FiO2 ) and inflammatory cytokines IL-1 ,6 ,8 ,and TNF-a level of two groups were compared .Results The total effi-ciency of the observation group was 94 .12% ,which was significantly higher than the control group that was 76 .47% (P<0 .05) . After treatment ,the arterial oxygen saturation (SaO2 ) ,arterial oxygen pressure (PaO2 ) ,PaO2/FiO2 of the observation group in-creased significantly ,and higher than the control group(P<0 .05) .After treatment ,IL-1 ,6 ,8 ,TNF-αof the observation group were significantly lower than the control group(P<0 .05) .Conclusion The treatment of early mechanical ventilation with perfluorocar-bon inhalation gasification could control the inflammation in patients with SAP complicated with AROS ,which could improve the cure rate .
4.Animal models of Peyronie's disease: An update.
National Journal of Andrology 2016;22(5):446-449
Peyronie's disease is characterized by local fibrosis of the tunica albuginea and relatively rare clinically. Few relevant basic researches could be retrieved, which might be attributed to the absence of a robust animal model of the disease as well as to its rareness. At present, some animal models available for Peyronie's disease have their own merits and demerits. TGF-β1-induced and Fibrin-induced models are lack of penile curvature and calcification/ossification. A surgical model might be established for the acute phase of the disease. The characteristic of a widespread fibrotic process involving many organs in the spontaneous model is quite different from that of human Peyronie's disease. Therefore, choosing the right model is essential for researches. This paper presents an overview of the animal models of Peyronie's disease, meant to provide some reference for the basic research of the disease.

Objective The aim of this paper was to investigate endothelial dysfunction,platelet activation, and inflammation in elderly hypertensive patients and those complicated with cerebral infarction. Methods Twenty-eight elderly hypertensive patients complicated with cerebral infarction(within 72 hours after onset of neurological symptoms),thirty-one Stage Ⅰ~Ⅱelderly hypertensive patients and twenty-eight elderly healthy individuals were selected as subjects.Their plasma concentrations of von Willebrand factor(vWF), alpha granule membrane protein-140(GMP-140), and serum concentrations of C-reaction protein(CRP) were examined. Results Elderly hypertensive patients complicated with cerebral infarction had significantly higher plasma vWF, GMP-140, and serum CRP than elderly hypertensive patients and elderly healthy individuals. Plasma vWF and GMP-140 were higher in elderly hypertensive patients than elderly healthy individuals, whereas serum CRP was increased slightly and there was no significant difference between elderly hypertensive patients and elderly healthy individuals. Conclusion This study suggests that elderly hypertensive patients complicated with cerebral infarction have obvious endothelial dysfunction, platelet activation, and inflammatory change. Stage Ⅰ~Ⅱ elderly hypertensive patients have obvious endothelial dysfunction and platelet activation as well.

AIM: To explore the different inhibitory effect of arsenic trioxide (As_2O_3) on hepatocarcinoma cell growth in SMMC-7721 and BEL-7402 cell lines and its mechanism. METHODS: The cell culture and trypan blue staining were used to study the inhibitory effect of arsenic trioxide on cell growth, and the glutathione (GSH) contents in hepatocarcinoma cells treated with arsenic trioxide were detected. RESULTS: Arsenic trioxide inhibited the growth of BEL-7402 cells in a time and dose-dependent manner. The inhibitory effect was significant at a lower dose of 0.50 ?mol/L for 24 h, however, to SMMC-7721 cells, a higher dose of 2.00 ?mol/L for 96 h was needed. The inhibitory rate of arsenic trioxide (0.25-2.00 ?mol/L) on BEL-7402 cell growth was higher than that on SMMC-7721 cells. The content of GSH in SMMC-7721 cells was much higher than that in BEL-7402 cells [(50.8?5.2) (?mol/g) protein and (18.7?1.4) ?mol/g protein, respectively]. CONCLUSION: There was a significant difference in inhibition of hepatocarcinoma cell growth by arsenic trioxide between BEL-7402 and SMMC-7721 cell lines, the cause of which may be due to the difference in GSH content in BEL-7402 and SMMC-7721 cells.

AIM: To express the synthesized human insul in like growth factor I (hIGF-1) gene in E.coli with high expression level a nd explore the way to increase the efficiency of factor Xa cleavage. METHODS: The gene of hIGF-1 was designed and synthesized accordi n g to the preference of E.coli. A fusion protein with a recognized site of fa ctor Xa between CBD (cellulose binding domain) and hIGF-1 was expressed and puri fied by cellulose affinity chromatography. MTT method was used to assay the bioa ctivity of CBD-IGF fusion protein. hIGF-1 was released by factor Xa. In order to improve the sensitivity of fusion protein to factor Xa, the short flexible pept ide (Gly-Thr-Gly- Gly-Gly-Ser-Gly) was added before the recognized site of fac tor Xa. RESULTS: SDS-PAGE results indicated that the CBD-IGF fusion prot ein was expressed and purified . Biological assay results indicated CBD-IGF fusi on protein could promote the growth of NIH3T3 cell. The short flexible peptide (Gly-Thr-Gly-Gly-Gly-Ser-Gly), which was added before the recognized site of f actor Xa, improved the sensitivity of fusion protein to factor Xa. CONCLUSION: CBD-IGF fusion protein with bioactivite are expresse d and purified. The amio acid sequences changes between the site recognize of fa ctor Xa can help to improve the cleavage efficiency of Factor Xa.
