Objective To investigate the expression of Oct-4 as a stem cell marker in gastric carcinoma tissues and its clinical significance. Methods From June 1996 to March 2006, 63 paraffin samples of gastric carcinoma tissues were obtained, and the expression of Oct-4 was examined by immunohistochemical staining. Another 58 normal tissues adjacent to gastric carcinoma and 10 normal gastric mucosa tissues were served as controls. The clinieopathologieal data of 63 patients with gastric carcinoma were retrospectively analysed, and their relationship with the expression of Oct-4 was analysed. Fifty of these 63 patients were followed up for 8 years, Kaplan-Meier method and Log-rank teat were employed to explore the correlation between Oct-4 expression and survival, and Cox Regression analysis was performed to evaluate the possibility of Oct-4 expression as an independent prognostic factor for gastric carcinoma. Results The positive expression rate of Oct-4 in gastric carcinoma tissues was 80.95% (51/63), significantly higher than that of normal tissues adjacent to gastric carcinoma (5.2%, 3/58) and normal gastric mucosa tissues (0) (P < 0.01). The expression of Oct-4 was positively correlated to the clinical stage of gastric carcinoma(P<0.01). There was no significant difference in the expression of Oct-4 among patients with different differentiation, age, and gender (P>0.05). Patients with higher expression of Oct-4 had significantly shorter survival time (P<0.05). The expression of Oct-4 was not significantly correlated with the prognosis of gastric carcinoma(RR, 0.554; 95% CI, 0.209-1.466). Conclusion The expression of Oct-4 is correlated with the clinical stage and survival time of patients with gastric carcinoma, however, it is not an independent prognostic factor for gastric carcinoma.

Objective To observe the effect of estrogen on H2O2-induced apoptosis and to explore the mechanism of protection by estrogen.Methods Setting up the experimental model of apoptosis induced by H2O2 in PC12 cells. The viability of cells was assessed by MTT assay. The activity of lactate dehydrogenase was detected by colorimetry. Hoechst 33258 was used as indicator of apoptosis. Apoptotic cells were measured by flow cytometry (FCM) with propidium iodide stain. The activity of caspase-3 was detected by colorimetry. Results H2O2 significantly decreased the viability of cell, increased LDH release and promoted apoptosis as well as caspase-3 activity in PC12. Estrogen markedly reduced these changes. Conclusion Estrogen reduces apoptosis induced by H2O2, and its mechanisms may be explained by inhibition of activation of caspase-3.

Small non-coding RNA (sRNA) is a kind of newly discovered 50 nt~500 nt small RNAs that do not encode proteins. To date, more than 150 sRNA have been found in bacteria. The small RNA acting by base-pairing with target mRNAs, resulting in post-transcriptionally regulating gene expression, is important regulators in the bacterial response to stress, virulence and metabolism. At present, researches of sRNA mainly based on bioinformatical prediction and molecular biological experiments. The sRNA that obtained through these methods needs confirmation in laboratory, and then study of its functions through a variety of experimental methods.

METHODS By surveying the hand-washing situation of 96 medical staff in our hospital through the method of sampling,the different germ eradication rate between routine soap hand-washing and disinfectant wet towel hand-wiping as well as hand-washing rate in all candidate population during practical work were observed. RESULTS The germ eradication rate after routine soap hand-washing was 86.0%,while by disinfectant wet towel wiping it was increased to 91.3%.The washing rate after above former method was 18.3% and after above two methods combined was increased to 43.6%,and after health propaganding and training was up to 60.6%. CONCLUSIONS Disinfectant wet towel hand-wiping is convenient,practical and effective which would be more suitable for clinical practice when combined with routine soap washing method.

Objective To study the value of laparoscopic cholecystectomy (LC) for treating gallbladder benign diseases in aged patients. Methods Laparoscopy cholecystectomy (3-port or 4-port) was performed in 2335 senile patients with gallbladder benign diseases from December 1992 to May 2005. Results Five patients were found as having the Mirizzi syndrome and were given a subtotal cholecystectomy. In 18 patients with a frozen Callot’s triangle, the anterior wall of the gallbladder was resected and the mucous membrane on the posterior wall was electrocauterized. LC was completed smoothly in the remaining 2312 patients. No conversions to open surgery were needed. The operation time was 8~55 min (mean, 19 min), and the intraoperative blood loss was 1~ 50 ml (mean, 8 ml). An abdominal drainage tube was placed in 213 patients, including double-cannula lavage in 56 patients. The length of hospital stay was 4~16 d (mean, 6 d). Follow-up examinations for 10 days ~13 years in 1859 patients showed no biliary stenosis, gallbladder pouch, or residual stones. Conclusions Laparoscopic cholecystectomy is safe and feasible in aged patients, being the first choice of operative method. Proper perioperative management, careful prevention co-morbidities, and control of operation time as short as possible are important for senile patients.

Objective To learn the incidence of the inherited metabolic diseases in Beijing. Methods Urine samples were analyzed by gas chromatography-mass spectrometry(GC-MS)for inherited metabolic diseases in high risky infants in Beijing . Results Urine samples from 411 high risky infants were analyzed by gas chromatography-mass spectrometry. 269 cases (65.5%) were detected to have metabolic abnormalities, including 19 cases (4.6%) diagnosed of inherited metabolic diseases in which there were 15 cases of methylmalonic academia and 1 case each of propionic academia, hyperphenylalaninemia, urea cycle abnormality and pyroglutamic aciduria. There were 22 suspected cases (5.4%) of inherited metabolic diseases including 13 cases of lactic acidosis, 5 cases of primary glycerol aciduria, 4 cases of fatty acid metabolic disorders including 1 case each of Citrin defects, tyrosinemia, galactosemia 3-methylcrotonoyl coenzyme A carboxylase deifciency and maple syrup urine disease. There were also 228 cases (55.5%) of metabolic abnormalities, such as increasing urine levels of lactic acid, sucrose,lactose, galactose, N-acetyl tyrosine, succinic acid, dicarboxylic acid and abnormal serine/threonine ratio. Conclusions Methylmalonic academia might be the most common inherited metabolic diseases in high risky infants in Beijing. For infants with clinical manifestations but unclear etiology, GC-MS should be performed. MS-MS and gene analysis could be combined if necessary.
