Objective: To study the significance of intracellular free calcium levels ([Ca 2+]i) and protein kinase C(PKC) levels in the process of human salivary gland mucoepidermoid carcinoma MEC-1 cell apoptosis induced by adriamycin. Methods: MEC-1 cells were treated with adriamycin at 10 ?mol/L for 30 s~24 h.Apoptosis of the cells was investigated by light and electron microscopy, agarose gel electrophoresis and flow cytometry. [Ca 2+]i was determined by flow cytomerty, PKC by Bardford method. Results: The results showed that MEC-1 cells presented classic morphologic features of apoptosis. [Ca 2+]i in the treated cells was increased from (36.63?0.61) nmol/L to (84.00?0.45) nmol/L after 30 s~24 h treatment,while that in the control cells was 17.43?0.47 (P

Objective To investigate the transactivating effect of hepatitis C virus(HCV)core protein on inducible nitric oxide synthase(iNOS)gene promoter and the molecular biological mecha- nisms of HCV pathogenesis.Methods Polymerase chain reaction(PCR)technique was employed to amplify the sequence of iNOS promoter by using HepG2 genomic DNA as template,and the product was cloned into pGEM-T vector.The iNOSp gene was cut from T-iNOSp by KpnⅠand XhoⅠ,and then was cloned into pCAT3-Basic,the constructed vector was named as pCAT3-iNOSp,pCAT3-iN- OSp was transfected into the LO_2 cell line.LO_2 cell was also cotransfected with pcDNA3.1(-)-core and pCAT3-iNOSp by FuGENE 6 transfection reagents.The LO_2 cells transfected with pCAT3-Basic was used as negative control.The activity of CAT in LO_2 cells was detected by an ELISA kit after 48 hours,which reflected the transactivating function of HCV core protein to iNOS gene promoter.Re- sults The expressive vector pcDNA3.1(-)-core and report vector pCAT3-iNOSp had been construc- ted and confirmed by restriction enzyme digestion and sequencing.The expression of CAT in LO_2 cells transfected with pCAT3-iNOSp and peDNA3,1(-)-core was 11 times as higher as that of pCAT3-bas- ic,and 6 times as higher as that of pCAT3-iNOSp.Conclusion It is suggested that HCV core protein can transactivate iNOS gene promoter.

Objective To study the feasibility of laparoscopic cholecystectomy accompanied by simultaneous umbilical hernia repair.Methods Twenty-four adult patients received laparoscopic cholecystectomy accompanied by simultaneous umbilical hernia repair in our hospital from November 2003 to April 2008.An incision was made in navel defect and entered the abdominal cavity under a direct vision.LC was performed by 3-trocar technique.Umbilical hernia was repaired by Mayo' style.Results The operation was successfully completed in all the cases.The operation time ranged from 35 to 65 minutes (mean,48 minutes),the blood loss was 5-30 ml(mean,16 ml),and hospital stay after the operation was 3 -4 days.No patient dereloped wound infection or skin necrosis.No recurreme was found during a 1-to 54-month follow-up(mean,28.6 months).Conclusions Laparoscopie cholecystectomy accompanied by simultaneous umbilical hernia repair is a safe and effective procedure.Mayo repair is simple and effective for umbilical hernia with less fascial defects.

In order to make a rational and effective cure measure for lung cancer,people need to establish suitable animal model.Spontaneous or induced model needs long time to form tumor and the rate is not steady.Xenograft mouse model is widely used in laboratories because of its steady tumor formation rate and less time in oncogenesis.Engineered mouse model which is based on genetic technology not only helps us to understand pathological process of lung cancer,but also can provide an ideal preclinical model of targeted therapy experiment,and it will be the important development direction of lung cancer animal model.

We have reported previously a peculiar type of neurons in the submucous nerve plexus in the intestine of guinea pigs, and named them tentatively the ′paralymphatic neurons′. In order to further study this type of neurons, the immunohistochemical observation for neuron specific enolase (NSE) reactivity of the enteric nerve plexus in guinea pigs was carried out in this investigation. We found that all the neurons in the enteric nerve plexus showed NSE positive reaction. The paralymphatic neurons located closely against to lymphatic vessels in submucous nerve plexus in small intestine and colon also exhibited same NSE positive reaction as other neurons. All the smooth muscle and connective tissue cells were NSE negative. Most of the paralymphatic neurons exhibited typical morphological features of neurons. Although some cells did not show obvious neuronal characters, but they all presented the same positive reactivity. Hence, this study provide another reliable evidence to confirm the exact neuronal nature of the paralymphatic neurons.
