1.STUDIES ON THE EFFECTIVE COMPONENTS IN PROTECTIVE SEKA AGAINST PLASMODIUM YOELII INFECTIONS IN MICE
Chinese Journal of Parasitology and Parasitic Diseases 1987;0(02):-
Sera were collccted from mice immunized separately with schizonts, merozoitcs or different parasite stages, or from mice which had been recovered from Plasmodium yoelii yoelii infection. The effect of protection of cach serum against P. y. infection was assayed by passivc transfer technique. It was shown that only sera collected from mice which either had been trcated with chloroquine or had been naturally recovcred from P. y. infections can transfer certain dcgree of resistance to normal mice. The cffectivc sera delayed the appearance and the peak of parasitemia, and prolonged the survival time of the challenged mice. After these sera were fractionatcd by 50%(NH4)2SO4 precipitation, the prccipitated fraction showed similar degree of protection as the non-fractionated sera. Chloroquine-treated serum was shown to be able to inhibit the invasion of new erythrocytes by marozoite in vitro. 35S-methionine-labelcd antigens were precipitated by protective or non-protective sera and the bands were compared on SDS-PAGE and autoradiogram. Since thc antigcn bands of 245, 210, 190, 156 and 130 KD can only bc precipitated by protective sera but not by non-protectivc sera, it is possible that the protection of chloroquine-treated serum is induced by the specific antibodies against the above antigens.
2.Preliminary Research on Anti-fatigue Effect of Tibet Maca in Mice
China Pharmacist 2015;(3):511-513
Objective:To explore the anti-fatigue effect of Tibet maca in mice. Methods: The mice were respectively given the powder or the alcohol extract of Tibet maca. The lactic acid concentration in blood, serum lactate dehydrogenase ( LDH) , the time of weight loading swimming and serum urea ammonia level after the exercise in the mice were detected, and the anti-fatigue effect of the powder and the alcohol extract of Tibet maca was compared. Results: After the 30-day feeding, the serum LDH activity of the mice taking the powder or alcohol extract of Tibet maca was obviously higher than that of the mice in the control group(P<0. 05), the time of weight loading swimming was significantly longer than that in the control group (P<0. 05), and the blood lactic acid concentration after the exercise was obviously lower than that in the control group (P<0. 05). Conclusion: Tibet maca can improve the time of weight loading swimming of mice, and reduce the level of serum urea ammonia after exercise and blood lactic acid concentration, sug-gesting the powder and alcohol extract of Tibet maca have obvious anti-fatigue effect.

4.Tension-free Vaginal Tape Obturator Inside-outside for Treating Female Stress Urinary Incontinence
Journal of China Medical University 2010;(3):231-233
Objective To explore the clinical efficacy of tension-free vaginal tape obturator inside-outside(TVT-O)in the treatment of female stress urinary incontinence.Methods In this study,we enrolled the patients with stress urinary incontinence who were treated with TVT-O(n=72)or midodrine hydrochloride(n=72).The patient self-evaluation and the Results of pad test and urodynamic test 6 and 24 months after the treatment were compared.Results These 2 kinds of treatment significantly improved the symptoms in patients with stress urinary incontinence,and in patients treated with TVT-O the clinical efficacy 24 months after the treatment was better.Conclusion TVT-O is safe and effective in treating female stress urinary incontinence,and the long-term follow-up and the improvement of urodynamic indices show it is better than simple drug treatment.

Purpose:To evaluate the clinical effect of late-course hyperfractionated (LCH) radiotherapy and conventionally fractionated (CF) radiotherapy for local advanced non-small cell lung cancer (NSCLC). Methods:From August 1995 to April 1998, 74 patients with inoperable stage Ⅲ NSCLC were randomized into two groups: CF and LCH. 37 patients in CF group received a fraction of 2 Gy daily, 5 days per week, to the total dose of 65~70 Gy /6.5~7 weeks. 37 patients in LCH group were treated with the same fractionation as CF group to the dose of 40 Gy, and then followed by LCH radiotherapy: 1.2Gy, twice daily, with the interval of 6 hours between fractions, to the total dose of 64 Gy/6 weeks. Results:The overall response rate in LCH group and CF group were 78.4%(29/37) and 62.2%(23/37) respectively, the difference was significant (P

BACKGROUND: Tongxinluo acts on benefiting qi, promoting circulation in collateral, activating blood circulation and resolving stasis, which is well effective in treatment of ischemic cerebral vascular disease. Single-photon emission computed tomography (SPECT) provides reliable reference evidence objectively and sensitively for clinical evaluation of therapeutic effects.OBJECTIVE: SPECT and clinical neurofunctional defect score (NDS)were used to observe the therapeutic effect of tongxinluo capsule on cerebral infarction.DESIGN: Case analysis was designed.SETTING: Internal Department of Neurology of First Affiliated Hospital of Chongqing Medical University.PARTICIPANTS: Totally 22 cases of acute cerebral infarction were admitted in Internal Department of Neurology of First Affiliated Hospital of Chongqing Medical University from March 2002 and July 2003, in which 12 cases were male and 10 cases were female, aged varied from 40 to 78 years, sick duration in range from 3 hours to 3 days.METHODS: Voluntarily, 22 cases of acute cerebral infarction were randomized in tongxinluo capsule group (capsule group)(11 cases) and the control (11 cases). In the control, danshen tablet was administrated,4 tablet/time, 3 times/d. In capsule group, tongxinluo capsule group was administrated, 4 pills/time, 3 times/d. The drugs were administrated for 15 days in two groups. Before and after treatment, SPECT ROI technique was used to assay ROI average radioactive counts on the affected and healthy sides to understand local blood flowing volume of brain in two groups. Neurofunctional defect evaluation was done before and after treatment on each patient.in two groups.RESULTS: Totally 22 cases of cerebral infarction all entered result analcontrol after treatment [(49.182±5.344 5), (28.364±4.610 3) score P < 0.001].the affected side of the control and treatment group before treatment was decreased. Fifteen days after treatment, the volume in original decreased flowing area of brain was improved after taking the capsule (66.536±18.676,ter administration of the capsule reflected in SPECT radionuclide, but it was not improved remarkably in the control.CONCLUSION: Tongxinluo capsule improves definitely cerebral blood flow in patients with cerebral infarction. With improvement of blood flowing in brain, the neurofunctional defect score is promoted clinically, too. It is explained that the capsule promotes the recovery of nerve function.
