In recent colleges entrance examination's reform , the subjects and content reform especially catch our eyes and receive favorable effect. But there appear some phenomena, which in fact do harm to education equity. They mostly embody the contradiction of measuring ability and principle of equity and objectivity, and the contradiction of city value's tropism and equity, and the influence that other factors impose on subjects and content reform and so on. In colleges entrance examination's reform, we not only stick to the reform's major direction, but also rightly understand equity problem, and will advance subject and content reform with synthesis and balance state.

Objective To study recent clinical efifcacy and safety analysis of tinidazole and metronidazole in treatment of severe oral infection. Methods, 88 cases with severe oral infection(SOI) collected in the third people's hospital of Wenling from April 2012 to April 2013 were divided into observation group (n=45) and control group (n=43) by random number table. Control group were received metronidazole drug treatment, while observation group were treated with tinidazole medication, The efifcacy, recovery duration and adverse reactions were compared between two groups. Results The efficacy of observation group was significantly better than control group, the difference was statistically significant (P<0.05). The average duration of symptoms and wound healing in observation group were (4.8±0.4)hs and (4.3 ± 0.2)hs, which were signiifcantly less than (5.5 ± 0.2)sh and (5.6 ± 0.1)sh in control group(P<0.05).Adverse reactions in observation group were signiifcantly lower than that in control group (P<0.05). Conclusion Tinidazole has a signiifcant effect and less adverse reactions in treatment of SOI.

Objective: Digital images processing is widely applied in the fields of biology and medicine, and some achievements have been gained by this technique. But there is few reports on measure the parameters of morphology of pathology from the patients which were threated by ovulation induction, by computer processing techniques. The work shows it has significant value in clinical diagnosis and reproductive medicine at present and in the future. Methods: Write the programmeces by Image Processing Toolbox in MATLAB. The original pathology images are preprocessed by 4 steps: step 1: read imagejstep 2: imopen the curve background brightness; step 3: adjust the background; step 4: adjust the contrast. Then segmentation image by 4 steps; step 1: read image; step 2: estimation the image; step 3: remove the noise; step 4: find the boundaries. The end, measure the parameters of morphology. Results: The pathology was studied percase for their area, perimeter, maximum diameter, equivalent diameter and metric. Conclusions: Image Processing Toolbox is useful to measure the parameters of morphology of pathology.

Dihydroartemisinin (DHA), a semi-synthetic derivative of artemisinin, has recently shown antitumor activity in various cancer cells including cancers of cervix, pancreas, prostate, liver and neuroblastoma. Numerous studies in vivo and in vitro indicate that DHA possesses unique antitumor features and appears to be a promising chemotherapeutic agents. Here we systematically review the advances in research of anticancer of dihydroartemisinin, as well as summarize the mechanisms of its inducing apoptosis,delay cell-cycle, inhibitory cell proliferation and downregulate angiogenesis.

Objective To compare the effect and survival period of endoscopic treatment group and non endoscopic treatment group of esophageal gastric varices bleeding in patients with hepatocellular carcinoma and portal vein tumor thrombus, in order to define the significance of endoscopic therapy for prolonging the survival period of patients. Methods 76 patients diagnosed as esophageal gastric varices bleeding with hepatocellular carcinoma and portal vein tumor thrombus from Jan. 2013 to Dec. 2015 were enrolled, of all these cases, 27 were non endoscopic treatment group and 49 were endoscopic treatment group. The medical records were analyzed retrospectively. Then compare the effect of emergency treatment, the main causes of death and survival time of the two groups. Results In the non endoscopic treatment group, 40.7% (11/27) patients died in one week after bleeding, 81.5% (22/27) patients died of esophageal gastric varices bleeding, the mean survival period was (42.03 ± 13.94) days; In the endoscopic treatment group, only 16.3% (8/49) patients died in one week (P < 0.05), 55.1% (27/49) patients died of esophageal gastric varices bleeding (P < 0.05), the mean survival time was (174.24 ± 34.42) days (P < 0.05). Conclusions Endoscopic therapy can effectively reduce the risk of death from acute hemorrhage and prolong the survival time in patients with hepatocellular carcinoma and portal vein tumor thrombus.

Objective To investigate the effects of Lipo-PGE1 on the expression of T-bet and Gata-3,and its potential mechanisms causing the shift of T cells from Th1 to Th2 on Acute lung injury(ALI)induced by Lipopolysaccharide(LPS)in mice.Methods Sixty male BALB-C mice were randomly divided into three groups(n =20 in each group):(1)control group,mice were treated with intravenous injection of NS in dose of 10 ml/kg,(2)LPS group,mice were exposed to LPS with dosage of 5 mg/kg(0.5 g/ml diluted in saline),and(3)LPS + PGE1 group,mice were treated with Lipo-PGE1 in dose of 15μg/kg.Sixhours after injection,the lungs were removed for observing the histopathological changes and determination of wet/dry lung weight(W/D)ratio.The levels of Th1 and Th2 were determined by flow cytometry,and the expressions of T-bet and Gata-3 mRNA were detected by using RT-PCR.One-way ANOVA was used for comparing differences between groups,and all data were presented in((x)± s).Results The histological changes of lung injury were lessened by PGEC ompared with the W/D ratio(5.74 ± 0.31)in LPS group,the one(4.92 ±0.27)in LPS +PGE1 group was lower significantly(P ＜0.01).The levels of Th1 and Th2 and their ratio Were higher in LPS +PGE1 group[(20.31 ±2.20)％,(10.50±0.80)％,(1.93±0.05)]than in LPS group[(16.65 ±1.70)％,(9.40 ±1.25)％,(1.73 ±0.03)](P＜0.01).Compared with control group,the expressions ofT-bet mRNA(1.183 ±0.495),and Gata-3 mRNA(0.693±0.285),and their ratio(1.713 ± 0.131)were lower(P ＜0.01); compared with LPS group,PGE1 significantly increased the expressions of T-bet mRNA(1.827 ± 0.705)and the ratio of T-bet/Gata-3 (2.502 ±0.352)(P ＜0.01),while didn(t)increased the expressions of Gata-3 mRNA(0.7191 ±0.186)significantly(P ＞ 0.05).Conclusions Lipo-PGE1 may up-regulate transcription factor T-bet which participates in the Th1 differentiation ratio,and then improve the inflammatorv svmntom.

Epigenetic modification includes DNA methylation, histone modification, non-coding RNA, etc., and is crucial in determining gene expression. A growing number of recent studies have shown that epigenetic regulation may play a central role in the pathogenesis of sepsis. Due to its explicit mechanism and relatively mature technic, DNA methylation has received extensive attention in sepsis-related researches.
