The control group was treated with prostaglandin synthetic inhibitor, and the treatment group was treated with modified Shenghua decoction on the basis of control group. Results The total effective rate of the treatment group and the control group was 90% and 73.3%, respectively, showing significant difference (X2=4.011, P <0.05 ) . Conclusion Modified Shenghua decoction plus western medicine is effective in treating, primary dysmenorrheal.

Objective To establish a method for simultaneous determination of 12 kinds of organophosphorus pesticides in water. Methods Organophosphorus pesticides in the water were extracted by liquid-liquid extraction, then analyzed with DB-1701 capillary column. In the same time, they were determined with GC by controlling the temperature and the speed of nitrogen. Retention time of the peaks was used for qualitative analysis, while external standard method was used for the quantitative analysis. Results The linear ranges of organophosphorus pesticides were 0.2～50.0 ?g/L, r≥0.999 1. The lowest detection limit was 0.009～0.04 ?g/L, the rate of recovery were 78.4%～93.9% and RSDs were 3.4%～7.5%. Conclusion This method is simple, rapid, sensitive and can efficiently separate and determine 12 kinds of organophosphorus pesticides in the water with 32.5 minutes of operation only.

Insulin resistance induces multiple metabolic disorders and are the common risk factors of diabetes mellitus and cardiovascular diseases.Since the causes are complex,the medical management should be integrated to treat insulin resistance.Lifestyle change is the first choice,and the appropriate agents can be selected if needed.

Objective To summarize the experience of laparoscopic appendectomy(LA).Methods A retrospective analysis was carried out on clinical data of 162 cases of laparoscopic appendectomy in this hospital from August 2002 to April 2005.Results Laparoscopic operation was completed in all the cases but 1 case of intestinal tuberculosis.The operative time was 30~90 min(mean,42 min) and the intraoperative blood loss was 5~10 ml.No complications were noted.Conclusions Laparoscopic appendectomy has advantages of little invasion,less blood loss,rapid recovery,and fewer complications,being a safe and ideal surgical alternative.

Objective To investigate the protective effect of ginsenoside Rb1 and Re on injury of the neonate rat cardiomyocyte induced by aconitine alkaloids.Methods The influence of aconitine and ginsenoside Rb1,Re together in neonate rat cardiomyocyte was observed respectively.The influence of these components in neonate rat cardiomyocyte was examined by myocard zymogram.The expression of Ca2+ channel gene Cav1.2 mRNA of neonate rat cardiomyocyte after treatment was observed by RT-PCR.Results The ginsenoside Rb1 and Re were able to decrease the release of AST and LDH,reverse Cav1.2 mRNA abundance induced by aconitine.Conclusion The ginsenoside Rb1 and Re which together with aconitine can alleviate the side effects and boost up the therapeutic effects of aconitine.The action mechanism may be relation with that the ginsenoside Rb1 and Re can decrease injuries of the neonate rat cardiomyocytes and abundant expression of Cav1.2 mRNA induced by aconitine.

Objective To explore clinical curative effect of microsurgery of petroclival tumors by transpetrosal presigmoid approach. Methods A series of 23 patients of petroclival tumors resected by microneurosurgery were analyzed retrospectively, including tumors histological types, clinical and preoperative MRI features, operative approaches, surgical technique and common postoperative complications. Results Total resection of the tumor was achieved microsurgically in 16 cases, subtotal resection in 4 cases, partial resection in 3 cases. No patient died in this series. 8 patients presented worsening crainal nerves palsies postoperatively. CSF leaks were uncommon, occuring in 2 patients. Conclusion The tumors in petroclival region can be totally resected by transpetrosal presigmoid approach. The advantages were offered by this approach such as the temporal lobes and cerebellum are minimally retracted; the operative distance of petroclival tumors is shortened with exposure of clivus and juxta-clival region.

AIM　To study the synthesis and anticancer activity of 3-［(3′-methyl-4′-(substituted phenyl)-1′,3′-butadienyl］ indole derivatives. METHODS　Electrophilic-substitution, aldol-condensation, selective-reduction, phase-transfer Wittig reaction and hydrolysis reaction were used in the synthesis of the title compounds. RESULTS　Eleven compounds of 3-［(3′-methyl-4′-(substituted phenyl)-1′,3′-butadienyl］ indole were synthesized. They are new compounds. Compound 8 showed different inhibitory effects on HL-60, HCT-8 and Bel7402 cell lines in vitro, and its inhibitory rate of antiinflammation was 100％ at 10-5 mol*L-1 concentration. CONCLUSION　Compound 8 showed high anticancer and antiinflammatory activities, and is worth further studying.

It has been demonstrated by animal and human experiments that the growth promoting effect of soybean milk substitute formula 5410 is comparable with that of human milk or cow's milk formula commonly used in infant feeding. It was assumed that such a favorable effect is due in part to the inclusion of 5% of egg yolk powder in the formula. However, such an assumption remains to be confirmed.In the present animal experiment, the 5% egg yolk powder was either removed (diet 5700), or substituted with 5% whole egg powder (diet 5411), 5% whole cow's milk powder (diet 5720), 10% whole cow's milk powder (diet 5721).It was fouad that the growth promoting effect of diet 5411 is the, same as that of 5410, while that of the other, diets are all significantly inferior than that of 5410. The role played by the definite amount of egg yolk in the soybean milk substitute is postulated.

AIM: To study the effects of different dose proportioning the danggui-shaoyao powder (DS) on learning and memory and the content of NO in brain in mice. METHODS: The ability of learning and memory was measured by the step-through task and the water maze task. The content of NO in brain was determined referring to the reagent manual. RESULTS: All different dose proportion of DS promoted the memory of normal mice. And only DS 1 (1 5.4) and DS 3 (1 1.34) obviously improved the scopolamine-induced mice passive avoidance handicap, prolonged the latency, and decreased number of errors. DS 3(1 1.34) obviously improved reserpine-induced mice spatial orientation handicap and prolonged the latency; others had no remarkable effect on spatial orientation handicap of mice. And all different dose proportions of DS could reduce the content of NO in the brain of passive avoidance disruption mice induced by scopolamine. CONCLUSION: DS 3 (1 1.34) improves passive avoidance handicap and spatial orientation handicap of mice, and reduced the content of NO in the brain of passive avoidance handicap mice induced by scopolamine. The effect of DS 3(1 1.34) is the best on benefiting memory.

OBJECTIVE: To optimize the preparation technology of phloroglucinol phospholipids complex and study its physicochemical properties.METHODS: The preparation technology for phloroglucinol phospholipids complex was optimized taking the molar ratio of phloroglucinol to phospholipids(A),reaction temperature(B) and reaction time(C) as factors and complex ratio of phloroglucinol and phospholipid as index.The dissolubility and oil/water partition coefficient of the complex in different solvents were determined and compared with crude drug,and the new complex's physicochemical properties were validated by UV and IR(infrared spectra).RESULTS: The optimized preparation conditions for phloroglucinol phospholipids complex were obtained as follows: A was 1∶2;B was 60 ℃ and C was 2 h.The complex ratio remained at above 98%.Compared with phloroglucinol crude drug,the phloroglucinol phospholipids complex in water or chloroform showed increase in both dissolubility and oil/water partition coefficient.UV and IR confirmed that no new complex had been formed from phloroglucinol and phospholipids.CONCLUSION: The optimized technology greatly enhanced the dissolubility and lipotropy of the phloroglucinol phospholipids complex.
