OBJECTIVETo observe the clinical efficacy of treating chronic persistent bronchial asthma (CPBA) children with abnormal myocardial enzyme spectrum (AMES) by Yupingfeng Powder (YP) combined routine therapy.
METHODSFrom January 2010 to December 2012, 156 CPBA children patients with AMES were randomly assigned to the treatment group (80 cases) and the control group (76 cases). All patients received routine treatment (inhaled corticosteroids and/or leukotriene regulator). Besides, those in the treatment group took YP. The treatment duration was 3 months. The scores of children asthma control test (C-ACT), pulmonary function (FEV,% and PEF%), myocardial enzyme spectrum were observed before and after treatment, and 3 months before and after treatment. The myocardial enzyme spectrum of 40 healthy children at the baby clinics during the same period were recruited as the control.
RESULTSCompared with the control group, creatine kinase isoenzyme (CK-MB), creatine kinase(CK), and lactate dehydrogenase (LDH) increased in the two treatment groups (P <0.01), but there was no statistical difference in AST (P >0.05). Compared with before treatment in the same group, CK-MB, CK, LDH, and AST decreased in the treatment group after treatment and 3 months after treatment (P <0.01). CK-MB, CK, LDH, and AST decreased in the control group 3 months after treatment (P <0.01, P <0.05).Compared with after treatment, CK decreased in the control group 3 months after treatment (P <0.01). C-ACT score, FEV(1),%, and PEF% all increased in the two groups after treatment and 3 months after treatment (P <0.01, P <0.05). Compared with after treatment in the same group, CK decreased in the control group 3 months after treatment (P <0. 01). Compared with the control group in the same period, post-treatment CK-MB and CK decreased (P <0. 01, P <0. 05), while post-treatment C-ACT score, FEV, %, and PEF% increased (P <0.05) in the treatment group (P <0.05).
CONCLUSIONYP could strengthen specific and non-specific immunity of the organism, and improve clinical symptoms and the level of myocardial enzyme spectrum.

After testing the resistance of Streptomycin to the strain NS-41-80 which is the Meilingmycin producer- Streptomyces nanchangensis , a lot of streptomycin-resistant ( str ) mutants were screened after the spores regenerated on the lethal media when they were treated with 4 different dosage of super-mutagent EMS. We have abtained the high-yield strain 80-5. 11-221 from these str mutants which only produces Meilingmycin and no Nanchangmycin in the rotation-flask experiments. The productivity of 80-5. 11-221 is 1521?g/mL 77. 9% higher than CK's 855?g/mL. After the shake flask fermentation experiment of 80-5. 11-221 for six generations, the productivity of F 2 and F 3 is stable and the productivity of F 4?F 5?F 6 decreases hastily with the increment of generations. It was showed that the chemical-resistance mutation of the strains had closely relation with yield mutation and the EMS dosage of the yield mutation was higher than the resistance-chemical mutation's through the statistical analysis between the dosage of mutation and the chemical-resistance mutational frequency?the variate capacity of the mutants' yield. A model of the resistance-chemical mutational labelling rational selection of the strain producing Meilingmycin was established.

OBJECTIVETo observe the difference in the analgesic effect on primary dysmenorrheal between acupuncture and sham acupuncture at Sanyinjiao (SP 6) during menstrual pain and evaluate the impact of psychological effect on acupuncture analgesia.
METHODSSixty subjects were randomized into an acupuncture group and a sham acupuncture group, 30 cases in each one. The conventional acupuncture and sham acupuncture were applied to Sanyinjiao (SP 6) on bilateral sides when menstrual pain began to attack and needles were retained for 30 min each time. Three menstrual cycles were required. The visual analogue scale (VAS) was adopted to determine the scores before and 0. 5 h, 1 h, 3 h, 6 h and 12 h after acupuncture during menstrual pain in each cycle separately.
RESULTSIn the acupuncture group, VAS score at each time point after acupuncture was reduced as compared with that at the previous one during menstrual pain in each menstrual cycle, indicating the significant difference (all P<0. 05). In the sham acupuncture group, the scores in 6 h and 12 h of acupuncture were reduced as compared with the previous one, indicating the significant difference (all P<0. 05). After acupuncture, VAS score at each time point in the acupuncture group was lower than that in the sham acupuncture group (all P<0. 05).
CONCLUSIONThe conventional acupuncture at Sanyinjiao (SP 6) achieves the significant analgesic effect on primary dysmenorrheal. The psychological placebo effect of sham acupuncture has no obvious impact on acupuncture analgesia.
