Objective To investigate the effect of JUC on the incisions for episiotomy.Methods Three hundred primiparas to undergo episiotomy in our hospital were divided into two groups in equal number.The experiment group was given JUC Spray before suturing and the control group did not use any solution.In the two groups,antibiotics were not used after the operation,and the incisions were only cleaned with 0.5%povidone-iodine 2 times a day.Result There were significant differences between the two groups in terms of postoperative pains,inflammation and healing in the wounds,and hospital stay(P<0.05).Conclusions Application of JUC after episiotomy could be long-acting in antibacteria.It can reduce wound pain,improve wound healing rate, decrease the medical cost and shorten the hospital stay.

OBJECTIVE:To study the effects of Clebopride(CBP)bioadhensive sustained-release tablets on experimental gas-tric ulcer and gastrointestinal motility disorder. METHODS:Gastric ulcer rat model was induced by ethanol and aspirin,and then divided into model group (normal saline),common tablet (CBP tablet 0.072 mg/kg) and sustained-release tablet high-dose and low-dose groups (CBP bioadhensive sustained-release tablet 0.072,0.036 mg/kg);normal rats were included in normal control group (normal saline);they were given relevant medicine intragastrically,twice a day for sustained-release tablet,three times a day for other. Ulcer area were observed 2 and 4 days after medication to calculate healing rate of ulcer(n=6). Gastrointestinal mo-tility disorder mice model was induced by atropine,and then divided into model group (normal saline),common tablet group (CBP tablet 0.1 mg/kg)and sustained-release tablet high-dose,medium-dose and low-dose groups(CBP bioadhensive sustained-re-lease tablet 0.1,0.05,0.025 mg/kg);normal mice were included in normal control group(normal saline);they were given rele-vant medicine intragastrically,once a day,for consecutive 3 days. The rate of gastric emptying and small intestinal propulsion were detected (n=6). RESULTS:Compared with normal control group,ulcer area of rats increased in model group;compared with model group,that of rats decreased in common tablet group and sustained-release tablet high-dose,low-dose groups,with statisti-cal significance (P<0.01);healing rates of gastric ulcer were 32.35%-48.24% 2 days after medication,and those were above 70% 4 days after medication. Compared with normal control group,the rate of gastric emptying and small intestinal propulsion in mice decreased in model group;compared with model group,those of mice increased in common tablet group and sustained-re-lease tablet high-dose,medium-dose,low-dose groups. The effects of sustained-release tablet high-dose and medium-dose groups were better than that of common tablet group;those difference had statistical significance (P<0.01 or P<0.05). CONCLU-SIONS:CBP bioadhensive sustained-release tablets have im-provement effects against gastric ulcer of rats and gastrointesti-nal motility disorder of mice.

OBJECTIVETo clinically investigate and identify the occlusal force as one of factors relative to formation of wedge-shaped defects.

METHODS123 subjects, selected from a group of middle-aged and elderly people in an urban area were divided into four groups: control, light, middle and severe group according to the severity of wedge-shaped defects. Cuspid, first and second premolars, and first molar in maxilla were examined for occlusal force by occlusometer, and the peak value of occlusal contact strain on every maxillary tooth was studied by photocclusion.

RESULTSSignificant reduce of occlusive force in the defected teeth was found than that of in the control teeth. The occlusal contact strain of first premolars with defects by photocclusion was statistically increased. The relative occlusal contact strain of first premolars and first molar of defects was higher than that of their proximate teeth.

CONCLUSIONOcclusal force could have relation to the formation of wedge-shaped defects.
