Objective　To study the effect of minielctrocholecystectomy(MEC) for gallbladder stone. Methods　The clinical data of 4,200 cases(1991-2000) undergoing MEC were analysed restrospectively; the results of different operotors for the MEC were compared. Results　All 4,200 cases were cured. Of them, 41 cases(0.98%) had serious complications, including intraoperative bleeding in 4 cases(0.09%), biliary tract injury in 18(0.43%); stress ulcer in 8(0.19%), and residual stones of biliary tract in 11(0.26%). Conclusions　MEC has the following advantages: less trauma, short operation time, fast postoperative recovery and lower expense. The different operotors on MEC have distinguish difference in the results. It is important to preven the complications of MEC.

Tutorial System is beneficial to improving the general disposition of undergraduate students,forming better learning atmosphere,enhancing the scientific research ability,broadening the pathway of contacting society,developing students' cognitive ability,and strengthening employment instructive work.Tutorial system for undergraduate students has been carried out for 4 years in our military medical university.After finding some problems of the work,making a summary of the beneficial experience and analyzing the cause of problems,we try to put forward some suggestions and take some optimization measures.

Background and purpose:Somatostatin receptors have been found in a variety of tumors and are therefore amenable to treatment with somatostatin analogs, like octreotide. However, the study of SSTRs expression has been rarely studied in nasopharyngeal cancer.We investigated the expression of somatostatin receptors gene subtypes in human nasopharyngeal cancer cell line CNE_ 2 . Methods:We have harvested cultured human nasopharyngeal cancer cell line CNE_ 2 . Using both techniques, reverse transcriptase-polymerase chain reaction (RT-PCR) and immunohistochemical assay, we analysed mRNA of different subtypes of somatostatin receptors in human nasopharyngeal cancer cell line CNE_ 2 .Results:The positive rate of somatostatin receptors subtype SSTR_ 1 SSTR_ 2 SSTR_ 4 was manifested in the human nasopharyngeal carcinoma cell line CNE_ 2 by RT-PCR and immunohistochemical assay. According to immunohistochemical assay, SSTR_ 1 and SSTR_ 2A showed strongly positive expression and SSTR_ 3 and SSTR_ 5 negative expression,respectively.Conclusions:There are more than one SSTR subtypes expressed in the human nasopharyndeal carcinoma cell line CNE_ 2 . This study demonstrated the presence of SSTR_1,SSTR_ 2 in the human nasopharyndeal carcinoma cell line CNE_ 2 .

OBJECTIVE: To investigate the level of H2-Ab1 in the nasal mucosa of mice with allergic rhinitis. METHOD: Twenty-four female 129/sv mice were divided into 2 groups: ovalbumin (OVA) group and control. The allergic rhinitis models were induced by classical method with OVA. After the last challenge, the pathological differences between the two groups were surveyed. The levels of H2-AB1 were measured by ELISA and quantitative real time PCR. RESULT: The expression of H2-Ab1 is higher in subjects with AR than that in controls (P < 0.05). CONCLUSION The levels of H2-Ab1 were highly increased in allergic rhinitis group, which might be associated with the pathogenesis of allergic rhinitis.
