This paper introduces a statistics method for the segmentation evaluation for the head MRI. A new evaluation scheme proposed, the evaluation result is analyzed objectively by the statistic method. Genetic neural network algorithm proves with a stronger antinoise ability than other ones. The statistic method is helpful for evaluating the segmentation objectively.

Acupoint,as the special body surface part where the qi of zang-fu and meridians infuses, arouses the effect of acupuncture and moxibustion. Through the exploration for the origin and the evolution of acupoint, and the integration of the related data about acupuncture-moxibustion theory and modern research, it is believed that acupoint is not fixed and it may be in a state of dynamic change. Also, it is bound up with body function. Acupoint is relatively static and the location is immobile while the body is in normal physiological status. When the body is under pathological condition,however, it is activated and the position is correspondingly changed.

Gene vector is defined as a tool which can carry and transfer gene or other nucleic acid material into cells. Its chemical nature can be protein or polypeptide, nucleic acid, lipide, carbohydrate, and other polar molecule or its compound. As an.important part of gene therapy, gene delivery system is also the bottleneck of gene therapy. There are two existent gene vectors defined as viral vectosr and non-viral vectors. Generally, high transfection efficiency can be achieved by the application of viral vectors. But the application of viral vectors has been restricted by its immunogenicity and mutngenic potential as side effects. As a novel gene delivery system, non-viral vectors have the advantages of low toxicity, low immunogenicity, and relative targeting effect. This article provides a review on the latest research progress about various kinds of vectors.

Objective To compare the differences in the efficacy of Bifidobacterium tetravaccine tablets.Bifidobacterium triple viable capsules and live Bacillus licheniformis capsule in the treatment of persistent and chronic diarrhea.Methods From September 2015 to June 2016,a total of 484 outpatients with persistent and chronic diarrhea were enrolled and divided into observation group (treated with Bifidobacterium tetravaccine tablets) and control group (treated with the combination of Bifidobacterium triple viable capsules and live Bacillus licheniformis capsule).Before and after treatment,the frequency of defecation and the characters of stool were observed and the differences in the treatment efficacy in persistent and chronic diarrhea between two groups were compared.Paired t test and Chi square test were used to compare the difference before and after treatment in each group,and independent sample t test was used for comparison between groups.Results There were a total of 256 patients in the observation group (four cases lost and 256 cases were completed).Meanwhile there were 228 patients in the control group (30 cases lost and 228 cases completed).In the observation group,after treatment the frequency of defecation was (2.13±1.06) times,which was less than that before treatment ((3.83±0.95) times),and the difference was statistically significant (t=29.149,P＜0.01).In the control group,after treatment the frequency of defecation was (2.19 ± 1.06) times,which was less than that before treatment ((3.87 ±0.98) times),and the difference was statistically significant(t =27.800,P＜0.01).There was no statistically significant difference in the frequency of defecation before and after treatment between two groups (t=-0.460 and-0.662,both P＞0.05).Furthermore there was also no statistically significant difference in the rate of normal bowel movements between observation group and treatment group after treatment (50.8％(130/256) vs 57.9％(132/228;x2=2.458,P=0.117).There was no significant difference in effective rate (64.8％(166/256) vs 69.7％ (159/228) and excellence rate (47.7％ (122/256) vs 51.3％ (117/228)) between two groups (P=0.253 and 0.422);besides,no severe adverse events were reported.Conclusion In the aspect of improving of times of defecation and characters of stool in patients with persistent and chronic diarrhea,single medication of multi bacteria strains Bifidobacterium tetravaccine tablets has the same satisfied efficacy and good safety as the combination of Bifidobacterium triple viable capsules and live Bacillus licheniformis capsule.

Objective To explore the effect of telbivudine on serum interleukin-18(IL-18),IL-12, IL-37 and tumor necrosis factor α(TNF-α) levels in patients with HBV-related hepatocirrhosis.Methods 66 cases of patients with HBV-related hepatocirrhosis were collected and divided into treatment group and control group according to the different treatment method , 34 cases in control group were treated with routine treatment , 32 cases in treatment group were treated by telbivudine on the basis of routine treatment.The serum IL-18, IL-12, IL-37, TNF-αlevels and adverse reactions were compared post-treatment.Results Compared with control group, the levels of IL-18, IL-12, IL-37 and TNF-αdecreased significantly post-treatment (P<0.05).The above levels were significantly lower in treatment group post-treatment than that in control group(P<0.05).Conclusion Telbivudine adjuvant therapy could suppress viral replication, and improve liver function and immune response in patients with HBV-related hepatocirrhosis.

β-Catenin is an adhesion molecule that mediates intercellular adhesion.It can be activated by the classical Wnt signaling pathway and promote cell survival.During cerebral ischemia,the stability of β-catenin decreases and the phosphorylated β-catenin level increases.Up-regulation of β-catenin can inhibit the schemia-induced neuronal apoptosis,promote neurogenesis,maintain the stability of blood-brain-barrier,and protect against cerebral injury.

Thymidine kinase 1 (TK1),an enzyme of the pyrimidine remedial pathway,can catalyze phosphorylation of thymidine to thymidine monophosphate.It is closely related to cell cycle regulation and cell proliferation.A number of experiments show that TK1 can be used for physical examination,tumor screening,routine testing,effect monitoring and prognosis evaluation,which is considered to be a sensitive and useful marker for human tumor growth.

Objective To explore the effects of patient mutual help-oriented nursing model on social support and hope level in lung cancer patients.Methods Totally 72 lung cancer patients were recruited into the study and divided into the experimental group and the control group with 36 patients in each group.The control group was given routine care,while the experimental group received additional patient mutual help-oriented nursing interventions:physically and psychologically well recovered patients were asked to give emotional communication and interaction to patients newly diagnosed with lung cancer,The Social Support Scale and Herth Hope Index were used for evaluation after the intervention.Results The patients' social support and hope level of the intervention group were significantly better than those of the control group after intervention.Conclusions Patient mutual help-oriented nursing model can improve social support and hope level of lung cancer.

Objective To translate the English version of Career Needs Questionnaires-Short Form (CNQ-SF) into Chinese and to test the reliability and validity of the Chinese version of CNQ-SF in cancer patients.Methods Totally 232 patients with cancer were recruited and were investigated by the Chinese version of CNQ-SF.Results The internal consistency coefficient of the Chinese version of CNQ-SF ranged from 0.792 to 0.937.The content validity index was 0.94.Factor analysis got five factors,which explained 69.8％ of the total variance.Conclusions The Chinese version of CNQ-SF has been proved to be reliable and valid.h can be used as a valid tool for the measurement of information needs of cancer patients.
