OBJECTIVE:To establish a RP-HPLC method for simultaneously determining 2 components in compound ornidazole suppository.METHODS:The HPLC method was performed on Symmetry C18 column(4.6mm?150mm),a mixture of methanol and 0.01mol/L KH2PO4 as mobile phase,and tinidazole as internal standard.The detection wavelength was set at 305nm,and flow rate was 1.0ml/min.RESULTS:The linear rangs of ornidazole and levofloxacin were 5～80?g/ml(r=0.9 997)and 2.5～40?g/ml(r=0.9 999)respectively.The average recovery(n=5)was (100.65?2.27)%for ornidazole,(98.86?1.28)%for levofloxacin.CONCLUSION:This method is rapid,simple and accurate and can be used for the quality control of compound ornidazole suppository.

OBJECTIVE:To probe the characteristics and regularities of drug-induced allergic shock.METHODS:The case reports of drug-induced allergic shock,published on Chinese medical periodicals during the period of1998to2003,were collected and analysed.RESULTS:Ocurrence rate and mortality of allergic shock induced by antimicrobials,Chinese materia medica and biologicals occupied the front3places in sequence,and drugs for intravenous administration resulted in the highest rate(61.30%).A large proportion of allergic shock was immediate type(78.73%).Drug-induced allergic shock was indepen?dent of sex and age.CONCLUSION:Allergic history should be taken in detail before the use,the indications of drug use strictly controlled and the ADRs observed so as to ensure the safe use of drugs.

OBJECTIVE:To optimize the extraction technology of total saponins from Litchi chinensis.METHODS:The extraction technology of total saponins from Litchi chinensis was optimized by orthogonal experiment taking the content of total saponins and extraction rate as indexes with the extraction solvent,the amount of solvent,the extraction time and extraction times as factors. RESULTS:The optimal extraction technology of total saponins from Litchi chinensis was as follows:70% ethanol as solvent,1 g medicinal powder(per 8 mL solvent),extraction time of 1 hour (extraction for 1 time). CONCLUSION:The optimum extracting technology is simple,feasible and stable,and it provides theoretic basis for the further utilization of Litchi chinensis.

PURPOSE To discuss induction and relation of synchronous multiple primary cancer to adenoma of large intestines. METHODS Continuous observation of resectable and pathologically proved cancer of large intestines of 166 cases. RESULTS We discovered 8 cases (4. 8%) of synchronous multiple primary cancer of large interstines. 43 cases of single primary cancer of concomitant adenoma (27. 7%). The 4 cases of synchronous cancer had merged adenoma (50%). The 4 cases of synchronous cancer had concomitant adenoma of 14 sites. Of these 2 cases had neoplastic change in 3 sites. The rate of neoplastic change was 50% concomitant adenoma. In the whole group, of the 18 cancer sites, 8 nidi were less than 3cm. CONCLUSION Synchronous cancer of large intestines is not rare, and is related to malignant change of adenomas. complete colonoscopy is an important means to improve diagnostic rate.

Purpose:To explore the value of predicting the axillary lymph node(ALN) metastases statu s by sentinel lymph node biopsy(SLNB) with methylene blue subcantaneously inject ion in the breast cancer patient and to provide the scientific basis for selecti ve axillary lymph node dissection(ALND) in breast cancer.Methods :1% methylene blue 2ml was subcantaneously injected at 4 sites of the skin over the tumor in each of 64 patients with breast cancer. Most of these were staged as T 1-2 N 0M 0, and a few were T 3N 0M 0. All patients underwent a S LNB 5 minutes after injection, followed by various ways of radical operation. Pa thohistological examination was assessed in all of SLN which included a frozen s ection intra-operation and a paraffin section after operation, and all other no n-SLN had a paraffin section.Results:The successful detection rate of SLN was 85.9%(55/64), and the accuracy of predi cting ALN metastases was 96.4%(53/55). The sensitivity was 90.9%(20/22), the sp ecificity was 100%(33/33), and the false-negative rate was 9.1%(2/22). The pred ictive value of a positive test and of a negative test were respectively 100%(22 /22) and 94.3%(33/35). In the resected SLN and non-SLN the metastases rates wer e respectively 29.4% and 8.3%(? 2=41.493, P

Objective: To investigate the antagonistic effect of lithium on the neurotoxicity of lead acetate and the possible mechanisms. Method: Wistar rats were randomly divided into control group, Pb group and four Pb+ LiCl groups fed with feed containing 3, 30, 300, 3 000 mg/kg LiCl respectively. All Pb exposed groups were given distilled water containing 0.2% PbAc. The changes of nNOS protein and gene expression in rats hippocampus were studied by ABC immunohistochemistry and the semiquantitative reverse transcription-polymerase chain reaction (RT-PCR) method. Rusults: Compared with the control group, the number of nNOS positive neurons in CA1 area and the nNOS mRNA content of hippocampus of LiCl (3, 30 mg/kg) groups were increased,while those of Pb-exposed rats were significantly decreased. Compared with Pb groups, the number of nNOS positive neurons and the nNOS mRNA content of Pb+LiCl (3,30,300 mg/kg) groups were increased. In dentate gyrus, the changes of the number of nNOS positive neurons coincided with the changes in CA1 area, but those in CA3 area showed little difference. Conclusion: Low dose of lithium could resist the lead neurotoxcity obviously.

Objective To observe the effects of parecoxib sodium on laparoscopic cholecystectomy ( LC ) patients after remifentanil fast track anesthesia.Methods 120 patients underwent general anesthesia for laparoscopic cholecystectomy were divided into two groups using random number table,60 cases in each group.The observation group was injected parecoxib sodium 40mg+saline solution 5 mL,while the control group was injected only saline so-lution 5mL prior to induction of anesthesia.The heart rate,mean arterial pressure,awaked time,pain score,agitation score and adverse reaction were compared.Results 5, 15, 30min after extubation, heart rate were ( 75.7 ± 4.8)times/min,(79.3 ±6.2)times/min,(74.2 ±5.2)times/min in the observation group and (85.2 ±3.8)times/min, (88.2 ±5.9)times/min,(86.1 ±6.2)times/min in the control group,and the mean arterial pressure were (103.5 ± 11.3)mmHg,(104.7 ±12.6)mmHg,(108.4 ±12.7)mmHg in the observation group and (132.3 ±16.3)mmHg, (135.2 ±14.6) mmHg,(133.6 ±11.8) mmHg in the control group,there were statistifically significant differences (t=4.722,4.357,4.236,4.732,4.367,4.063,all P <0.05).The pain score,agitation score were (2.5 ± 0.9)points,(1.4 ±0.8) points in the observation group,which were lower than (4.2 ±1.2) points,(3.2 ± 1.2)points in the control group(t =4.232,5.234,all P<0.05).Conclusion Parecoxib sodium can reduce the fast-track anesthesia agitation and pain,improve hemodynamics and stress response in LC patients.
