Résumé
Acute abdomen in pregnancy can be divided into pregnancy-related and non-pregnancy-related type. This article reviewed the different types of acute abdomen caused by gynecological problems during pregnancy. Also, the progress of laparoscopic surgical technique and the perioperative management and the influence of the operation on pregnancy outcomes in patients who developed acute abdomen and underwent laparoscopic surgery in pregnancy were also analyzed, to provide information for the application of emergency laparoscopic surgery in pregnancy.

OBJECTIVE:To study the anti-tussive and anti-inflammatory effects of aqueous extract of Pegaeophyti Radix Et Rhizoma(P. Radix Et Rhizoma). METHODS:In the experiment,there were a model group,a positive control group [30 mg/kg co-deine for mice,18.38 mg/kg codeine for guinea pigs,20 mg/kg indometacin for mice and 15 mg/kg indometacin for rats] and P. Ra-dix Et Rhizoma low-dose,medium-dose and high-dose groups [2.0,4.0 and 8.0 g(medicinal materials)/kg for mice;1.2,2.4 and 4.8 g (medicinal materials)/kg for guinea pigs;1.4,2.8 and 5.6 g (medicinal materials)/kg for rats],with 10 animals in each group. The above-mentioned animals were given corresponding drug ig for 4 consecutive days,and then strong ammonia spraying method and sulfur dioxide stimulation method were employed to induce cough in mice and citric acid spraying method to induce cough in guinea pigs to observe the incubation period and times of cough,auricular swelling method to observe xylene-induced au-ricular swelling in mice and pedal swelling method to observe carrageenin-induced pedal swelling in rats. RESULTS:Compared to the model group,Aqueous extract of P. Radix Et Rhizoma could prolong the incubation period and reduce times of cough induced by strong ammonia spraying and sulfur dioxide stimulation in mice of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups;it could prolong the incubation period of and reduce times of cough induced by citric acid spraying in guinea pigs of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups;it could alleviate xylene-induced auricu-lar swelling in mice of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups;it could alleviate carra-geenin-induced pedal swelling in rats of positive control group and P. Radix Et Rhizoma medium-dose and high-dose groups. There were statistically significances (P<0.01 or P<0.05). CONCLUSIONS:Aqueous extract of P. Radix Et Rhizoma has anti-tussive and anti-inflammatory effects on the experimental animals.
Résumé
Objective To analyze the genotypes of clinical varicella-zoster virus(VZV) isolates in Tibet.Methods The samples of vesicular fluid from patients with chickenpox or zoster were collected to isolate VZV in human embryonic fibroblast cells.Furtherly,the isolated VZV were identified by indirect immunofluorescence assay and the positive ones were continuely cultured in vitro to get their genome DNAs.Then,PCR and nucleotide sequencing were performed on the part of open reading frames 1,21,50,54.To confirm the genotypes of isolated virus strains,the gene sequences obtained from PCR products were compared with that in GenBank of VZV Dumas strains,and their restriction enzyme sites were analyzed via Primer 5.0.Results Ten clinical isolates of VZV were obtained from sixteen specimens,the positive isolation rate was 62.5％.Gene analysis showed that among all the ten clinical isolates of VZV in Tibet,three strains are genotype A1,four are genotype A2 and the other three are genotype J1.Conclusion The VZV genotype distribution in Tibet was tightly related to their special geographic locations.
Résumé
With the change of medical mode and deepening of the medical education reforms,such educational idea as giving prominence to practice is widely used to improve students' comprehensive quality and innovative ability and practice ability. The medical shool of Tibet university has established long-term apprentice mechanism during the before class and playtimes and found four county hospitals, five health clinics in towns and townships and gradually improved the construction of mutual win-win 9clinical teaching bases. In this way it has been cultivating many advanced medical personnels, who are reliable, available, able to stay, and highly praised by the employers.
