OBJECTIVE:To study the optimum conditions for extracting the effective components in Yansheng oral liquidMETHODS:Using orthogonal design L9(34),the content of total solid was taken as the screening indexInfluence of the concentration of alcohol on effective components was observedRESULTS:The number of times of extraction(D) had significant influence on the content of total solid(P

Objective To observe the effects of phlorohlucinol on cervical dilatation. Methods Totaling 250 normal parturients were randomized into four study groups (50 in each group) and control group (n=50). Phloroglucinol was given in the study groups(group1,2,3 and 4)at the dose of 40 mg to the cervix and/or 160 mg and 200 mg intravenously during the latent phase. The control group (group1) received only atropine (0.5 mg) intravenously. Results The overall speed of cervical dilatation in the study group was (2.82?1.82) cm/h and (1.78?1.01) cm/h in the control group. The mean time of the first stage of labor was (14.23?1.11) h and (17.71?2.23) h in the study and control group, respectively (P

Objective To evaluate the different effect of 50 g glucose challenge test (GCT) on screening the glucose intolerance at different gestational age. Methods Two thousand pregnant women were divided into 2 groups(1000 in each). Women in group A received 50 g GCT at 14 and 28 gestational weeks respectively and 75 g oral glucose tolerance test (OGTT) were performed in those cases with abnormal 50 g GCT. 50 g GCT was performed after fasting at 14 gestational weeks and repeated one hour after a meal at 28 gestational weeks. Women in group B were screened by 50 g GCT at 28 gestational weeks and followed by 75 g OGTT for those with abnormal 50 g GCT. The diagnostic effect of 50 g GCT for screening at different weeks of gestation with different ways was evaluated. Results (1)The rate of abnormal result of 50 g GCT was higher in fasting cases than that of cases testing after meal (15.6% vs 12.2%, P

Objective To observe the effects of diazepam on the cervix in relieving spasm, eliminating edema and improving dilation during the latent phase of labor. Methods One hundred normal parturients were randomly devided into study group ( n =50) and control group ( n =50). The study group was injected diazepam 10 mg in the cervix during the latent phase. The control group was given 10 mg of diazepam by intravenous injection. Results The dilating speed of cervix in study group was 2.81?1.92 cm/h. The mean time of the first stage of labor was 11.13?1.21 h, while the control group was 1.98?0.92 cm/h and 13.34?0.44 h respectively. The differences between two groups were statistically significant ( P

Objective To discusses the effect of different nursing methods on anastomotic healing after low colorectal surgery. Methods 60 patient with colorectal cancer undergoing low anastomosis were randomly divided into the experimental group and the control group with 30 cases in each.The experimental group adopted modified nursing care,while the control group received routine nursing care.The defecation times and incidence of complications were observed between the two groups.Results The defecation frequency of the experimental group was less than the control group,and the incidence of rectal stimulation sign,anastomotic fistula and obstruction was less in the experimental group.Conclusions Modifed nursing methods have certain effects on preventing postoperative complications of low colorectal anastomosis.

Objective　To review the anatomic and visual outcomes of a series of patients with macular holes who underwent vitreous surgery without adjunctive therapy.Methods　We performed a retrospective review of 16 patients who underwent vitrectomy, fluid-gas exchange and perflu oropropane(C3 F8) gas temponade for 14 eyes with idiopathic and 2 eyes with traumatic macular holes.Results　Anatomical closure of the macular holes was achieved in 15(93%) of 16 eyes with an average follow-up of 7 months. Only one eye needed performing second surgery. Three(19%) eyes achieved postoperative visual acuity of 0.4, four (25%)eyes 0.2～0.3,and nine(56%)eyes 0.1 or worse. Conclusions　Vitreous surgery without adjunctive therapy with intraocular gas tamponade and postoperative posturing is a well tolerated and effective intervention for idiopathic or some traumatic macular holes. Anatomical closure of the macular hole is associated with a significant improvement in visual acuity in most eyes.

Objective:To study the influence of different methods on serum soluble intercellular adhesion molecule1 (sICAM1) in patients with acute cerebral infarction. Methods: Double antibody enzyme-linked immunoadsorbent assay was used. Results and Conclusion: Scalp point-to-point acupuncture has a significant reducing effect on abnormally elevated serum sICAM1 in patients with acute cerebral infarction. Its curative effect is superior to that of simple Western medicine. There is a significant difference between them (P＜0.05).

The authors punctured the acupoints Jianyu (LI 15), Jianliao (TE 14), Jianzhen (SI 9), Binao (LI 14), Quchi (LI 11), Shousanli (LI 10) and Hegu (LI 4) and applied massage to the affected regions to treat 32 cases of the myotenositis of long head of biceps brachii. The results showed 8 cases were cured, 10 cases were remarkably effective, 11 cases were effective and 3 cases got no effect; the total effective rate was 90.6%.

OBJECTIVETo explore the induction of L-forms of Mycobacterium abscess using isoniazid.

METHODSMycobacterium abscess were cultured in aqueous culture media in the presence or absence of 128 µg/ml isoniazid. The culture media containing isoniazid were filtered with 0.45 µm membrane, and the filtrate was subcultured in nutrient agar media for reversion. The isoniazid-free and isoniazid-containing media and the reversion bacteria were observed for cell wall integrity by cell wall staining and transmission electron microscopy, and the microstructures of the cell surfaces were observed by scanning electron microscopy. The isoniazid-containing culture was subcultured in L-form agar media, and the isoniazid-free culture and the reversed bacteria in nutrient agar media to observe the colony morphology. The reversed and non-induced bacteria were identified for 16S rDNA.

RESULTSThe bacteria induced with 128 µg/ml isoniazid showed cell wall defect, presenting with a spherical cell morphology and typical fried egg-like colonies in L-form agar media, while in isoniazid-free cultures, the cells showed intact cell walls with rod-like shapes and round colony morphologies on nutrient agar. The reversed bacteria, showing also intact cell walls with rod-like shapes and round colonies on nutrient agar, had identical 16S rDNA with the non-induced bacteria.

CONCLUSIONIsoniazid can induce the L-forms of mycobacterium abscess for use in studies of multidrug resistance and treatment of the bacteria.
