Moyamoya disease is a chronic progressive cerebrovascular disease. Its main manifestation is bilateral internal carotid artery progressive stenosis w ith abnormal vascular netw ork formation of the compensatory hyperplasia in brain base. The pathological mechanism of moyamoya disease is not clear. Grow ing evidence has suggested that immune inflammation may play an important role in its occurrence and development process. Abnormal expression of various inflammatory cytokines and immune proteins can be observed in patients w ith moyamoya disease. This article review s the possible mechanism of immune inflammation in moyamoya disease in recent years.

Medical students' education of medical ethics is now influenced by many unfavorable factors,such as absence of humanities quality,weakening belief in ideality and shock from the market economy.General education may play an important role in strengthening humanities quality and belief in ideality among medical students,and correcting their cognition of the market economy.Therefore,it is necessary to deepen general education on strengthening medical students' education of medical ethics.

Objective To observe the effect of omeprazole combined with Kangfuxin liquid on immune function,gastrin family and NO levels in patients with gastric ulcer.Methods 120 cases of patients with gastric ulcer from October 2014 to September 2016 in our hospital were selected and randomly divided into the observation group and the control group with 60 cases in each group.The control group was given omeprazole based on conventional treatment, and the observation group was given Kangfuxin liquid based on the control group.For four weeks, to observe the differences of immune function (CD3 +,CD4 +,CD8 +,CD4 +/CD8 + and CD4 +CD25 +FoxP3 +Treg), gastric gastrin family (GAS, CCK, MTL) and NO levels between the two groups.Results After treatment, the CD3 +, CD4 +, CD8 +, CD4 +/CD8 +and CD4 +CD25 +FoxP3 +Treg levels of the two groups were compared, the difference was statistically significant (P<0.05), CD3 +, CD4 +, CD4 +/CD8 + of the groups showed a gradually increasing, the difference was statistically significant (P<0.05) and CD8 +, CD4 +CD25 +FoxP3 +Treg showed a gradually decreasing, the difference was statistically significant (P<0.05), and the change range of the observation group was more than that of the control group, the difference was statistically significant (P<0.05), the GAS,CCK,MTL levels of the two groups were compared, the difference was statistically significant (P<0.05), the GAS, CCK of the two groups showed a gradually decreasing, the difference was statistically significant (P<0.05), and MTL showed a gradually increasing, the difference was statistically significant ( P<0.05 ) , and the change range of the observation group was more than that of the control group , the difference was statistically significant (P<0.05), the NO levels of the two groups were compared, the difference was statistically significant (P<0.05), NO of the groups showed a gradually increasing, the difference was statistically significant (P<0.05), and the change range of the observation group was more than that of the control group, the difference was statistically significant (P<0.05).Conclusion Omeprazole combined with Kangfuxin liquid can get better regulating results of immune function and gastrin family, NO in patients with GU, and have more effective than omeprazole alone.

The expression of transforming growth factor-beta1 (TGF-beta1) in placental tissue of pregnancy-induced hypertension (PIH) and the relationship between the level of expression of TGF-beta1 and the amount of vascular cell adhesion molecule-1 (VCAM-1) in serum was studied. Immunohistochemistry ABC was used to detect the expression and distribution of TGF-beta1 in placental tissues in 40 PIH women and 20 normal pregnancy women. High resolution pathological image analysis system was used to determine the quality of TGF-beta1. The VCAM-1 in serum was examined by enzyme linked immunoabsorbent assay (ELISA). The results showed that TGF-beta1 could be express in syncytiotrophoblast. The levels of TGF-beta1 expression in placental tissues of the patients with moderate and severe PIH were significantly higher (P < 0.05), while the serum VCAM-1 was significantly lower than in normal group (P < 0.01). There was a significant positive correlation between the expression of TGF-beta1 in placental tissues and the serum VCAM-1 (r = 0.969, P < 0.01). It was concluded that the level of TGF-beta1 expression in PIH was increased and was positively correlated with the amount of serum VCAM-1, indicating that they might be involved in the pathogenesis of PIH.

Objective To examine the differentially expressed invasion-related genes in two anchorage-independent uterine cervical carcinoma cell lines derived from the same patient using a cDNA array. Methods Two human uterine cervical carcinoma subclonal cell lines CS03 and CS07 derived from a single donor line CS1213 were established by limited dilution procedure. The two cDNA samples retro-transcribed from total RNA derived from CS03 and CS07 cells were screened by a cDNA microarray carrying 234 human cell-cycle related genes and 1011 human signal transduction and membrane receptor -associated genes, scanned with a ScanArray 3000 laser scanner. Results The cDNA microarray analysis showed that 12 genes in CS03 were up-regulated compared to CS07, and 24 genes in CS07 were up-regulated. The function of a number of differentially expressed genes was consistently associated with cell-cycle, cell proliferation, migration, apoptosis, signal transduction and tumor metastasis, including p34cdc2, TSC22, plasminogen activator inhibitor I (PAI-1)and desmosome associated protein(Pinin). Conclusion Multiple genes are differentially expressed in uterine cervical carcinoma cell lines even came from the same patient. It is suggested that these genes are involved in the different phenotypic characteristics and development of cervical carcinoma.

Objective To explore the characteristics of uhrasonography of hepatobiliary cystadenoma. Methods The ultrasonographic characteristics of 5 cases with hepatobiliary cystadenoma were retrospectively analysed, and compared with the operation and pathology. Results The ultrasonography of 5 cases was multilocular cystic mass,which seems to be,but not indeed communicating with the biliary tree,in which irregular septation was demonstrated in two-dimensional structure and also with perforator vessels along in color Doppler flow imagineg. And in some cases small papillary tuft and small loci of calcification was noted on the septation. Conclusions Muhilocular cystic mass,locating along the biliary tree, however not communicating with the the biliary tree, is an important diagnostic basis of biliary cystadenoma. And it should be distinguished with other cystic tumor in the liver.

Epidemics of hand, foot and mouth disease (HFMD) have mainly been caused by Coxsackievirus A16 (CVA16) and Enterovirus A 71 (EV-A71), which circulated alternatively or together in the affected area. CVA16 has caused numerous outbreaks and epidemics in multiple countries and geographical regions, and has become an important public health problem. Based on an analysis of the complete VP1 coding region, all CVA16 strains can be divided into genotypes A, B1, and B2. Furthermore, genotype B1 can be divided into subgenotypes B1a, B1b, and B1c. After 2000, no reports of genotype B2 virus strains have been reported. All of the CVA16 strains reported in mainland China have belonged to subgenotypes B1a and B1b. Most CVA16-associated infections cause only mild symptoms; however, some CVA16 infections can lead to severe complications and even death. Vaccination is considered to be the most effective method to control the transmission and infection rate of this virus. A number of research groups are studying various vaccine types, including inactivated vaccines, genetic engineering vaccines, and DNA vaccines, amongst others. In this review, an overview is provided of the research advances in molecular epidemiology and vaccines of CVA16.
