Objective: To observe the clinical efficacy of thunder-fire moxibustion for hypomenorrhea after induced abortion. Methods: A total of 74 patients with hypomenorrhea after induced abortion were randomized into two groups, with 37 cases in each group. The control group was treated with conventional hormone sequential therapy, and the observation group was treated with thunder-fire moxibustion. The course of treatment was 3 menstrual cycles. The traditional Chinese medicine (TCM) symptom scores, menstrual volume, endometrial thickness and the sex hormone levels were observed before and after treatment. The clinical efficacy was compared after treatment. Results: The total effective rate in the observation group and the control group was 91.4% and 73.5%, respectively, and the difference between the two groups was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased significantly (all P<0.05), and the scores in the observation group were lower than those in the control group (P<0.05). The menstrual volume, endometrial thickness and each sex hormone level of the patients in both groups were significantly improved after treatment (all P<0.05), and the improvements in the observation group were more significant than those in the control group (all P<0.05). Conclusion: Thunder-fire moxibustion can significantly improve the clinical symptoms of patients with hypomenorrhea after induced abortion; it can increase menstrual volume and endometrial thickness, and regulate the sex hormone levels, producing a better curative effect than the conventional hormone sequential therapy.

Objective To explore the expression and significance of uncoupling protein (UCP)2in rats models of acute liver failure (ALF). Methods Thirty-six healthy male SD rats were randomly divided into normal control group and model group, and the model group was divided into 5 subgroups:6, 12, 24, 36 and 48 hours sub groups with 6 rats in each sub group. The rat model of ALF was established by intraperitoneal injections of D-galactosamine (D-Gal) and lipopolysaccharide (LPS).Sections of liver tissue were stained with hematoxylin and eosin and observed under optical microscope.UCP2 and UCP2 mRNA in rat liver were determined at different time points with immunohistochemical method and reverse transcription-polymerase chain reaction ( RT-PCR ),respectively. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) levels and malondialdehyde (MDA) concentration in the liver tissues were analyzed at the same time points.Comparisons among all the experimental groups were done by SNK test. Results Infiltration of inflammatory cells and necrosis of hepatic cells were marked in model group,and ALT, AST and MDA in model group were significantly higher than those in control group [(24. 0 ± 2. 0) U/L, (82. 3±16. 9) U/L, (2. 55±0. 22)μmol/g] at all time points. And they reached a peak at 24 h [(8346. 7±1363. 1) U/L, (9766. 7±1274. 1) U/L, (8. 34±1. 13) μmol/g; all P<0. 05]. UCP2 and UCP2 mRNA expressed scarcely in the liver tissues of control group, while increased markedly from 6 to 48 hours after D-Gal/LPS challenge in model group (P<0. 05). They both reached a peak at 24 h. And the discrepancy between consecutive experimental group had statistical significance ( P < 0. 05).Conclusions The rat model of ALF was established successfully by intraperitoneal injections of D-gal and LPS. The expression levels of UCP2 mRNA and UCP2 are consistent with the extent of liver injury and the level of oxidative stress in the rat model of ALF.

Objective To establish the in vivo models of adriamycin(ADR)-induced cardiotoxicity in rabbits, investigate the protective effect of oxymatrine (OMT) on ADR-induced cardiotoxicity, and explore the possible mechanism. Methods Twenty-six rabbits were randomly divided into ADR group (n=8, 2 mg/kg ADR), OMT group (n=5, 10 mg/kg OMT), ADR + OMT group (n=8, 10 mg/kg OMT was injected 30 min before ADR injection) and saline group (n=5, same quantity of normal saline), and rabbits in each group were infused with medicine or normal saline through ear marginal vein once a week for 8 weeks. The apoptosis of myocardial cells was detected by TUNEL methods, and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) was determined. Results After treatment, the body weight of ADR group was significantly lower than that of the other groups(P < 0.05), the activity of SOD and GSH-Px significantly decreased and the apoptosis index (AI) was significantly higher than that of the other groups(P <0.01). There were similar while minor changes in ADR + OMT group. There was no significant adverse effects in OMT group. Conclusion OMT protects heart from adriamycin-induced injury in rabbits, which may relate to the decrease in level of antioxidant and apoptosis of myocardial cells.

Twenty-five hybrid dogs were injected intravenously with oleic acid of the dose 0.3 ml/kg of body weight to prepare a model of respiratory distress syndrome (RDS) . The animals were killed 24 hours after injection. PaO2, PaCO2 and pH of the arterial and mixed venous blood were determined before and immediately, 0.5, 1?2, 4, 6, 22 and 24 hours after injection. The average pulmonary arterial pressure was measured hourly. The chest x-ray films were taken 2,4, 6 and 24 hours after injection. The electrolytes T3, T4, the hematocrit and RBC count, and the serum corticosteroid level were measured before and 24 hours after injection.25 dogs were divided into two groups; the control group consisted of 8 dogs and the therapeutic group consisted of 17 dogs, among which nine were treated with hyosine hydrobromide and 8 with dexamethasone. The histologic specimens of the animals of the control group and hyosine hydrobromide treated group were examined with both light and electron microscopes but the specimens of the animals of dexamethasone treated group were examined with light microscope only.It was found that dexamethasone is effective in the treatment of RDS produced with oleic acid injection while hyosine hydrobromide is of no value.

OBJECTIVETo develop an experimental rat model of inflammatory bowel disease (IBD) by administration of dextran sulfate sodium (DSS), and to observe changes in the tight junction protein expression and permeability of colon mucosa.
METHODSMale Sprague-Dawley (SD) rats were randomly divided into control (n=27) and IBD model groups (n=27). In the IBD model group, IBD was induced by 6-day administration of 3% DSS in water followed by 14-day administration of water only. The control group was fed with water only. Pathological changes in colon mucosae were observed on days 7, 14 and 21 after DSS administration. Colon tissue specimens were collected on day 21 for measuring myeloperoxidase (MPO) activity. The transepithelial electric resistance (TEER), transepithelial potential difference (TEPD) and short circuit current (Isc) of the specimens were measured by Ussing chamber. Real-time PCR and Western blot were used to measure the mRNA and protein expression of tight junction proteins in colon epithelia.
RESULTSIn the IBD model group, diarrhea, hemafecia and weight loss were seen. Inflammation occurred mainly in the distal colon and was characterized by crypt abscess and inflammatory cell infiltration. The IBD model group showed significantly increased MPO activity (P<0.01), significantly decreased TEER (P<0.01) and TEPD (P<0.01), and significantly increased Isc (P<0.01) compared with the control group. No claudin 2 expression of mRNA and protein was detected in the control group, and they were expressed in the IBD model group. The expression levels of claudin 3, occludin and ZO-1 in the IBD model group were significantly decreased compared with in the control group (P<0.01).
CONCLUSIONSIBD rats show colonic barrier dysfunction and changes in the expression of tight junction proteins. The changes in the expression of tight junction proteins may contribute to colonic barrier dysfunction in cases of IBD in the chronic recovery stage.

Objective To compare the diagnostic value of renal ultrasound scan (RUS) and 99Tcmdimercaptosuccinic acid (DMSA) renal scintigraphy in children with acute pyelonephritis (APN). Methods In all, 165 children with initial clinical diagnosis of APN, aged from 1.5 months to 11 yrs ( median 20 months), were included in the study, all of which were examined with RUS and DMSA renal scientigraphy. The diagnosis with DMSA renal scientigraphy results was taken as the standard reference to evaluate the diagnostic sensitivity and specificity of RUS. Results Of 99 out of all 330 kidneys that were found abnormal on DMSA renal scientigraphy, 31 were abnormal on RUS. Of the rest normal kidneys on DMSA scans renal scientigraphy, 4 were abnormal on RUS. Thus diagnostic sensitivity of RUS for APN was 31.3%(31/99) and specificity was 98.3% (227/231). Conclusions Although RUS provides with high diagnostic specificity for children with APN, its low sensitivity may underestimate the clinical evaluation of APN.More often than not, 99Tcm-DMSA renal scientigraphy is a clinical necesscity for the definite RUS diagnosis.
