OBJECTIVE:To study the time-effect and dose-effect of paeonol on the apoptosis of knee osteoarthritis(OA)artic-ular chondrocyte in rabbits and the mRNA expression of its related protein Bcl-2 and Bax. METHODS:60 big-ear rabbits were ran-domly divided into normal (normal saline) group,model (normal saline) group,paeonol high-dose,medium-dose and low-dose groups and triamcinolone acetonide(positive drug)group,with 10 rabbits in each group. Except for normal group,OA model was induced by right knee anterior cruciate ligament (ACLT) and the medial meniscus 1/3 resection in those groups. After modeling, different doses of paeonol(0.8,0.4,0.2 mg/kg),triamcinolone acetonide 0.2 mg/kg were injected into right articular cavity twice a week. 4 weeks and 8 weeks after administration,articular cartilage specimens were collected. Ultrapathological structure changes of articular chondrocytes were observed by electron microscope. Apoptosis of cartilage cell was observed by TUNEL and apoptotic index was calculated. mRNA expression of apoptosis related genes of Bcl-2 and Bax in articular cartilage tissue of rabbits were de-tected by in situ hybridization technique. RESULTS:Compared with normal group,articular chondrocyte of model group showed early and middle stage apoptosis morphology change after 4 and 8 weeks,and apoptosis index increased significantly and the mRNA expression of Bcl-2 and Bax was up-regulated (P<0.01);4 and 8 weeks later after administration,compared with model group,apoptosis index decreased and mRNA expression of Bax was down-regulated in paeonol groups,while mRNA expression of Bcl-2 was up-regulated(P<0.05 or P<0.01). Electron microscopy ultrastructural observation showed articular chondrocyte of pae-onol high-dose and middle-dose groups were in early stage of apoptosis.CONCLUSIONS:Paeonol can slow down articular chondro-cyte degeneration and destroy in OA model rabbits in time and dose dependently. Its mechanism may be associated with expression up-regulation of Bcl-2 and expression down-regulation of Bax.

Objective To investigate the effects of four interior-warming drugs( galangal,cinnamon,evodia rutaecarpa,and dried ginger)on the tension of ileum smooth muscle and Ca2+-ATPase on the cell membrane in rabbits. Methods The effects of galangal,cinnamon,evodia rutaecarpa,and dried ginger were examined on normal ileum smooth muscle,in vitro intestinal muscle contraction caused by acetylcholine(ACh),barium chloride(BaCl2 )and histamine(His), and ACh-induced calcium release by using BL-420E+ biological signal collection and processing system.The average tension was measured within 1 min before delivery and within 3 minutes after the treatment,and the inhibition rate was calculated according to the average tension value.The effects of sera containing galangal,cinnamon,evodia rutaecarpa,and dried ginger on Ca2+-ATPase activity on the cell membrane of the intestinal smooth muscle were examined by phosphorus method. Results Galangal,cinnamon,evodia rutaecarpa,and dried ginger at high concentrations could restrain in vitro intestinal contraction in normal circumstances(P<0.05 or P<0.01).Significant inhibitory effects on intestinal contraction caused by ACh,His and BaCl2 were found in low,medium and high concentration groups(P<0.01).There was a dose-effectiveness relationship between the inhibition rate and final drug concentrations.The ACh-induced intracellular and extracellular calcium dependent contraction were significantly inhibited by the four interior-warming drugs( P < 0. 05 or P < 0. 01). The Ca2+-ATPase activities were( 0. 384 ± 0.070),(0.302±0.016),(0.307±0.016),(0.296±0.016),(0.313±0.003)U·mg-1 ,respectively,in intestinal smooth muscle in normal control group and high concentration groups of galangal,cinnamon,evodia rutaecarpa,and dried ginger(P<0.01). Conclusion Interior-warming drugs may relax intestinal smooth muscle by reducing the intracellular calcium release and the extracellular calcium inflow via receptor-controlled calcium channels,and inhibiting the Ca2+-ATPase activity in smooth muscle.

Objective: To determine the potency of QN-2013, a derivative of quinoxaline 1,4-N-oxide, as a hypoxia-selective cytotoxin or a radiosensitizer. Methods: In vitro cytotoxicity and radiosensitization, as well as in vivo antitumor activity were determined by colony formation and tumor growth delay respectively. The changes in the cell cycle, DNA damage and repair of damaged DNA were assayed by FCM and “comet” assay, separately. Results: ICN250 and ICair50 of QN-2013 for HeLa-S3 cells were 0.08 and 1.7 mmol*L－1 respectively, namely, HCR=21. This suggested that QN-2013 was a fairly hypoxic cytotoxin, but inferior to SR-4233. QN-2013 had an evident radiosensitization either in vitro or in vivo. It was noted, however, that the value of in vitro SERs increased exponentially with increasing concentration of the drug, but the in situ antitumor activity seemed to be independent of doses of the drug. The systemic toxicity of QN-2013 was superior to an LD50 of 265　mg*kg－1 compared with 80　mg*kg－1 for SR-4233. In hypoxic condition QN-2013 induced S retension effect and G2M block in HeLa-S3 cells, caused DNA double strand break, and inhibited the repair of radiation-induced DNA damages. All of these reactivenesses might be involved in the action mechanism of QN-2013. Conclusion: QN-2013 is a fair hypoxia-selective cytotoxin, and has shown improved antitumor activity in vivo in combination with radiation. In general, These results suggest that the series of quinoxaline di-N-oxide derivatives hold out bright prospect for the development of novel bioreductive antitumor drugs.

The clinical data of 113 early pregnant (11-14 weeks) women with high risk of placenta accreta undergoing ultrasound examination in Jinhua Maternal and Child Health Hospital from June 2013 to June 2018 were retrospectively analyzed.Among them,there were 21 cases of placenta accreta (implanted group) and 92 cases without placenta accreta (non-implanted group).The diagnostic value of different μltrasound signs for placenta accreta was assessed.The sensitivity of loss of clear zone was 71％(15/21),and the specificity was 87％ (80/92);the sensitivity of placental lacunae and bladder wall interruption was 67％(14/21) and 62％(13/21),and the specificity was 78％(72/92) and 95％(87/92),respectively.The uterovesical hypervascularity has the lowest sensitivity (38％,8/21),but the highest specificity (98％,90/92).When combination of 2 sings was used for diagnosis,the sensitivity of the ultrasound examination was 76％ (16/21) and the specificity was 65％(60/92);when the combination of 3 signs was used,the sensitivity and specificity were 76％ (16/21) and 93％ (86/92),respectively.It is suggested that ultrasound examination in early pregnancy may find all types of placenta implants with good diagnostic accuracy.
