Objective In this research,the relationship between blood estrogen level and periodontitis in rats was studied. Methods Twenty-four female Wister rats were randomly divided into three groups:control group,sham operation group and ovariectomized group. Rat chronic periodontitis model was established by ligating the rat's second molar with a steel wire in the sham operation group and ovariectomized group. Serum estrogen level of the rats was detected respectively. Dental X-ray observation,histological examination and immunohistochemistry were employed for the characterization of rat's chronic periodontitis. Results Compared with both control group and sham operation group,a significant decrease in scrum estrogen level was observed in ovariectomized group (P

With the understanding of tumor metabolism, the process and mechanism of tumor metabolic reprogramming gradually attracted much attention in recent years.Oncogenes and tumor suppressor genes are constantly changing the pathway and flux of tumor metabolism in tumorigenesis to meet the needs of tumor growth and proliferation.The role of c-MYC, TP53, HIF-1αas well as the related signal pathways in tumor metabolic reprogramming would be discussed.

Objective To inquire into the changes of learning and memory ability and the level of SP, VIP in the brain of the model of Spleen insufficiency. To observe the influence invigorating spleen and restoring virility on above changes. Methods Establishing the spleen insufficiency model of rat by adopting bitter decline diarrhea, wild eating and overworking, to examine influence of invigorating spleen and restoring virility on the ability of learning and memory with the change of SP and VIP in the brain. Results In the period of study and remember of the water maze experiment, the swim whole distance time was long and mistake number was many in the model group; the swim whole distance time was short and the mistake number was little in the group of invigorating the Spleen and restoring virility. In the period of study and remember of the diving platform experiment, the mistake number of times is more and the incubation period was short in the model group; the mistake number was less and the incubation period was long in Spleen invigrating group. At the period of remember mistake number was more. In the model group, the immunoreaction masculine substance of SP level decrease obviously in the hypothalamus ventral kernel, the hippocampi CA1 area and forehand cortex; on above mentioned parts, the group of invigorating spleen and restoring virility increases distinctly, in the group of restoring virility increases distinctly in the hippocampi CA 1 area and forehead cortex, but decreased in hypothalamus ventral kernel. In the model group, the immunoreaction masculine substance of VIP level decreased obviously;in the hippocampi CA1 area and cortex;on above mentioned parts, the groups of invigorating spleen and restoring virility increases obviously. Conclusion In the model group, the ability of learing and memory with SP and VIP level in the brain changed. Invigorating spleen and restoring virility can improve above changes remarkably.

Objective To observe the change of umbilical artery S/D value in the third trimester pregnant women with overt hypothyroidism(OH) or subclinical hypothyroidism(SCH).Methods We collect the data of 37-42 weeks pregnancy from January 2014 to December 2015.We devided them into OH group,SCH group and contral group.We compared the umbilical artery S/D value in these three groups and analyzed the relativity between S/D value and thyroid hormone.Results The S/D value was 2.46 ± 0.31 in OH group,2.48 ± 0.27 in SCH group and 2.32 ± 0.17 in control group.The differences were statistically significant between OH group and contral group (P =0.000),SCH group and contral group (P =0.000).There was no statistically significant between OH group and SCH group (P =0.907).The proportion of cases number during different S/D value range in these three groups had difference (P =0.000).The S/D value was positively correlated to TSH in OH group (r =0.186,P =0.037) and SCH group (r =0.146,P =0.015).There was no correlation between FT3 and S/D value(P ＞ 0.05) or FT4 and S/D value(P ＞ 0.05) in both OH and SCH group.There was no correlation between thyroid hormone and S/D value in the contral group either.Conclusion Both OH and SCH can effect umbilical artery S/D value in the third trimester pregnancy.

Objective To investigate the clinical study of sarcoside combined with tamsulosin in the treatment of type Ⅲ prostatitis. Methods 84 patients with type Ⅲ prostatitis who were treated and diagnosed in Jishuitan Hospital from November 2015 to December 2016 were randomly divided into experimental group and control group according to the time of hospitalization, 42 cases in each group. The control group was treated with tamsulosin hydrochloride sustained-release capsules, and the experimental group was treated with the addition of the new drug. The maximum urinary flow rate and mean urinary flow before and after treatment were recorded, compared and analyzed before and after treatment. Results The maximum urinary flow rate and mean urinary flow rate were increased in both groups after treatment, and there was significant difference between the two groups (P<0.05). The data of the maximum urinary flow rate and the mean urinary flow rate in the experimental group were significantly better than those in the control group. The data of the two groups were statistically significant (P<0.05). In addition, the experimental group after treatment of prostate symptom score was significantly better than the control group score, the two groups of data were significantly different, the data were statistically significant (P<0.05). In addition, the total effective rate of the experimental group was significantly higher than the control group(80.95%vs. 73.81%). The data were statistically significant (P<0.05). Conclusion The clinical efficacy of sorbenaside combined with tamsulosin in the treatment of type Ⅲ prostatitis is better than that of the original treatment. The treatment can improve the patient's urination and prostate symptoms and improve the patient's comfort.

Objective To compare the Poser and the McDonald diagnostic criteria for multiple sclerosis (MS).Methods Sixty-seven patients with clinical features suggestive of MS were re-evaluated by 2 neurologists utilizing both the Poser and the McDonald criteria.The Fisher' s exact test was used to statistically analyze the data from assessment by these two criteria.Results By the Poser criteria, 34 patients were classified as clinically definite MS, 24 patients as laboratory supported definite MS and 9 patients as possible MS.Under the new McDonald criteria, MS was diagnosed in 36 patients and 31 patients had possible MS.The results revealed significant differences in diagnosing MS between these 2 criteria (OR=5.549, 95% CI 2.37-13.00, P<0.01).Conclusions These 2 criteria showed remarkable differences in diagnosing MS, in particular definite MS, possibly due to greater reliance on paraclinical evidences in the Poser criteria and more stringent gnidlines of magnetic resonance imaging (MRI) in the McDonald criteria.The analysis of cerebrospinal fluid may increase the diagnostic rate of MS and specify pathologic abnormalities in MRI to some degree.
