The clinical effects of 3 groups were evaluated and compared at baseline,and 1,6,12 months after restoration using modified USPHS criteria.The results were analyzed statistically by SPSS 13.0.Results It was not found that 110 defective teeth were debonded at 12 months after restoration.There were significant differences in assessment results of secondary caries,marginal fitness,appearance and color matching at 12 months after restoration by different restoration methods (χ2 =6.705,7.768,6.910,11.624,all P <0.05).Conclusion The dental restorations with CAD/CAMzirconia all -ceramic crowns and CAD/CAM zirconia all -ceramic onlays show satisfactory clinical performance in short time.

Objective] To explore the evolution of the names of smallpox. [Method] Reviewing the names and symptoms of rash diseases in ancient medical works, clarify the history of smallpox.[Result] The original name of smallpox is“ luchuang”“ wandouchuang”, referring to a single disease; in Songjinyuan Periods, the name was changed to “ chuangzhen”“ douzhen”, confusing with other rash diseases; in Ming Dynasty, the name was changed to“ douchuang”“ douzheng”, referring to a single disease again;smallpox appeared in Qing Dynasty. [Conclusion] Smallpox, a single disease at first, was confused with other rash diseases such as measles, and then differentiated from other rash diseases gradually. The evolution reflects the progress of traditional Chinese medicine in practical experience and theoretical summary.

BACKGROUND:There is a close relationship between tumor stem cels and tumor occurrence and recurrence, but there are stil some disputes in the presence of tumor stem cels in al tumors.
OBJECTIVE:To investigate the differentiation and culture of tumor stem cels in human primary gastric cancer cels.
METHODS:Primary gastric cancer cels isolated from fresh gastric cancer tissues were stained with hematoxylin-eosin and identified by immunohistochemical detection of carcinoembryonic antigen. The CD44 expression of the cels was detected using immunofluorescence method. Magnetic activated cel sorting was used to isolate CD44+gastric cancer cels that were then seeded subcutaneously behind the armpit of mice. Growth of implanted tumor cels was observed.
RESULTS AND CONCLUSION:Human primary gastric cancer cels were isolated in serum-free medium. Compared with the routine culture group, the number of CD44+cels(P< 0.05)and the tumor volumewere significantly increased in the spheroid culture group. Furthermore, at 90 days after transplantation, the tumor volume of mice in spheroid culture group was significantly higher than that in the routine culture group. These experimental findings indicate that gastric cancer cels with certain tumorigenicity can be successfuly isolated from gastric cancer cels using serum-free culture method and magnetic activated cel sorting method.

ObjectiveTo obtain data related to various periods of acupuncture treatment for rat focal ischemia and reperfusion and infer the optimal time point of acupuncture treatment by examining cerebral ROCK expression on the ischemic side in different periods of acupuncture for rats with focal ischemia and reperfusion.MethodOne hundred andeighty male adult Wistar rats were enrolled and randomly allocated to blank, sham operation, model and acupuncture groups. The model and acupuncture groups were separately divided into 5 subgroups: the 6 h, 24 h, 48 h, 72 h and 2 w subgroups. There were atotal of 12 groups, 15 rats each. An animal model of focal cerebral ischemia was made using a thread occlusion method for obstructing rat right middle cerebral artery. The carotid artery was only separated in the sham operation. Materials were taken in the blank and sham operation groups on day 2 after model making. Materials were taken for examination in every subgroup of the model group at 6, 24, 48 and 72 hours and 2 weeks after model making. Materials were taken for examination after acupuncture at Baihui(GV20), Dazhui(GV14)and Zusanli (ST36)in every subgroup of the acupuncture group at 6, 24, 48 and 72 hours and 2 weeks after model making.ResultAcupuncture markedly improved neurological deficits in rats with cerebral ischemia and reperfusion. Areduction in the neurological deficit score was largest in the 6 h acupuncture group and there was a statistically significant difference compared with the other acupuncture groups (24 h, 48 h and 72 h) (P<0.05). There was no statistically significant difference in ROCK expression between the sham operation and blank groups (P>0.05). There was a statistically significant difference in ROCK expression between the model (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and blank groups (P<0.05). ROCK expressionreached the peak value at 6 hours after ischemia and reperfusion. There was a statistically significant point-to-point difference in ROCK expression between the acupuncture (ischemia-reperfusion 6 h, 24 h, 48 h and 72 h) and model (ischemia-reperfusion 6h, 24 h, 48 h and 72 h) groups (P<0.05). ROCK expression was down-regulated most markedly in the ischemia-reperfusion 6 h acupuncture group.Conclusion Acupuncture has an inhibitory effect on Rho/Rock in a rat model of cerebral ischemia and reperfusion. Six hours after ischemia and reperfusion is the optimal time point of acupuncture treatment. Acupuncture at that time can protect and improve post-ischemic injured brain tissue to the largest extent.

Objective To investigate the effects of Nicergoline on swallowing function,substance P level and cognitive function in stroke patients.Methods A total of 60 patients developing stroke within 1-3 months with swallowing and mild to moderate cognitive impairments were selected and randomly divided into Nicergoline group (n=30,patients taking Nicergoline 20 mg,tid,for 4 weeks) and control group (n=30,patients taking placebo for 4 weeks).The swallowing function was evaluated,change of serum P substance level and the improvement of cognitive function were observed after 4 weeks of treatment.Results The swallowing function was improved in Nicergoline group after 4 weeks of treatment as compared with pre-treatment [(7.15 ± 1.76) scores vs.(5.42±1.89) scores,t=3.669,P=0.001],while it had no significant difference in the control group before versus after treatment (t=0.115,P=0.909).The substance P level was increased in Nicergoline group after 4 weeks of treatment as compared with pre-treatment [(189.6 ± 41.3) ng/L vs.(112.3±38.5) ng/L,P＜0.01],and it was slightly increased in control group after treatment,but there was no significant difference (t=0.933,P=0.355).In Nicergoline group,MMSE and MoCA scores were higher after treatment than before treatment [(24.77±5.75) vs.(19.22±2.36),(18.53±5.42) vs.(14.02±3.52),t=4.891 and 3.822,both P=0.000],while they had no significant differences in control group before versus after treatment (both P＞0.05).Conclusions Nicergoline can improve swallowing function and reduce the incidence of aspiration pneumonitis as well as improve the cognitive function in stroke patients.
