Human rotavirus (RV) is one of the main pathogens that cause non-bacterial acute gastroenteritis diseases globally. Live attenuated vaccine is an effective method to prevent RV infection. In order to improve the safety of RV vaccines, it is a good choice to develop other forms of vaccines other than live virus vaccines to avoid attenuated vaccine strains to restore virulence through back mutation or cause environmental contamination. This article reviews the research of RV virus like particle(VLP) vaccines.

Objective To analyse CT and MRI features of intracranial chondromas and review the literatures.9 cases of intracra-nial chondromas confirmed by operation and pathology were presented.Methods Among 9 cases,cerebral CT scan was performed in 8 cases(8/9),MRI scan in 4 cases(4/9)with spin-echo T1 WI,T2 WI,FLAIR,DWI sequences and enhanced T1 WI sequences.Results The lesions located at the skullbase in 8 cases,the dural convexity in 1 case.CT showed that the lesions were spot,strip or arc of fringe calcifications in 8 cases.MRI showed that the lesions were inhomogeneous low and moderate signal intensity on T1 WI and in-homogeneous high and moderate signal intensity on T2 WI in 4 cases(4/4).Multinodular or lobed high signal intensity was seen on T2 WI in 2 cases(2/4),coralline septal moderate signal intensity was seen on T2 WI ,which was obvious enhancement after adminis-tration of contrast medium on T1 WI in 2 cases(2/4),the envelope of the lesions was also obvious enhancement in 4 cases.Conclu-sion CT and MRI features of intracranial chondromas are marked.The MRI features of intracranial chondromas can reflect its path-ologic and histologic characteristics.

Objective To compare the effect of traditional open surgery and laparoscopic repair of gastric perforation on postoperative pulmonary function.Methods Fifty patients were divided into two groups according to therapeutic method.Group A underwent traditional open gastric perforation repair(n=25).Group B underwent laparoscopic repair of gastric perforation(n=25).The pulmonary functions were examined at 1 day,3 days and 7 days postoperatively.Results All patients had different degrees of postoperative pulmonary function decline.After operation,the forced vital capacity(FVC)and forced expiratory volume in 1 second(FEV1)and vital capacity(VC)in group A were significantly lower than those in preoperation(P<0.05).The patients in laparoscopic operation group decreased significantly only on the first day postoperative.The postoperative pulmonary function of patients undergoing open surgery was significantly lower than that of patients undergoing laparoscopic surgery(P<0.05).Conclusion Laparoscopic repair of gastric perforation has less damage to the lung function than traditional open gastric perforation repair.Laparoscopic surgery plays an important role in the recovery of postoperative pulmonary function.

Objective To investigate the effect of xenon intervention on delayed neuropsychologic sequelae (DNS)in acute carbon monoxide(CO)poisoning.Method Adult Wistar rats were randomly divided into sustained group,early intervention group,and control group.CO(150 ml/kg)was infused by intraperitoneal injection to produce DNS model.In sustained intervention group(S-group),xenon(150 ml/kg/d)was infilsed by intraperitoneal injection for 2 weeks;in control group(C-group),xenon was replaced by equal volume air;and in early intervention group(E-tvoup),xenon(150 ml/kg/d)was,employed in the first 3 days and air(150 ml/kg/d)was substituted for xenon in the following days until 2 weeks after CO poisoning.Morris maze test was used to evaluate the intelligence of rats.The long-term potentiation(LTP)of hippocampus Was detected by neuroelectricity recording.The apoptosis rates in brain was detected by TUNEL staining.The data were expressed as(x±s)and analyzed with student's test and analysis of variance.A P value less than 0.05 indicated statisfical significance.Results After exposure to CO,poisoned rats showed intelligence decline,demyeliation ofwater matler and cell apoptosis increased,which were consistent with DNS.In S-group and E-group,the rates of DNS and apoptosis were significantly lower than those in C-group,whereas the rote of LTP in S-group and E-group Was significantly higher than those in C-group.Conclusions Early xenon intervention can effectively decrease the rates of DNS occurred after acute CO poisoning.

Chinese traditional culture is the soil for the survival and development of traditional Chinese medi-cine,among them,the concept of A thing is valued if it is rare portal factions and master has influenced the development,communication and popularization of traditional Chinese medicine.But the spirit and thinking of harmony unity of heaven and man comparative state benevolence and self-cultivation and self-re-straint has played an active role in the development of traditional Chinese medicine.Thus this paper put forward the suggestions and opinions of strengthening the cultivation of humanistic spirit of higher traditional Chinese medi-cine talents:establishing a comprehensive evaluation standards of higher traditional Chinese medicine talents,es-tablishing scientific development concept to treat the inheritance and innovation of traditional Chinese medicine cul-ture,perfecting the curriculum provision of relevant professions,creating the conducive environment for the trans-mission of traditional Chinese medicine culture,hoping to provide a reference for the explanation of the relationship between traditional culture and traditional Chinese medicine.

Objective To observe the effect of short-term treatment with metfbrmin on psychological distress and metabolic feature in patients with polycystic ovary syndrome(PCOS).Methods Ninety women were diagnosed as cases of PCOS based on the 2003 Rotterdam criteria.These patients were divided into three groups:group A,consisted of 26 subjects treated with mefformin only; group B,36 cases treated with metformin plus Dane-35 ; and group C,28 cases treated with placebo and Dane-35.The treatment was carried out for 3 months.Clinical and metabolic parameters were observed.The psychological distress was evaluated by the hospital anxiety and depression scale(HAD scale).Results Compared with group C,patients in group A and B showed significantly lower body mass index(BMI),waist circumference (WC),waist-hip ratio (WHR),serum fasting insulin,homeostasis model assessment for insulin resistance (HOMA-IR),total cholesterol (TC),triglyceride (TG),low density lipoproteincholesterol(LDL-C) levels as well as anxiety and depression scores,but higher high density lipoprotein-cholesterol (HDL-C) levels (all P＜0.05).Compared with group A,patients in Group B had significantly higher WC,WHR,and LDL-C levels(all P＜O.05).No significant differences in BMI,TG,HDL-C,anxiety and depression scores were found between group A and B (all P＞0.05).In group A,a positive correlation was found between the changes of metabolic feature (BMI,WHR,and HOMA-IR) and the changes of anxiety and depression scores (all P ＜0.05).Conclusion Short-term treatment with metformin will benefit patients with polycystic ovary syndrome,regarding psychological distress and metabolic features.

Objective To verify the application of anterior segment perfusion culture and trabecular meshwork (TM) organ culture for glaucoma study. Methods TM tissue was cultured by perfused anterior segment and TM organ culture, light microscopy was used to observe the TM cells and intercellular spaces.Results IOP of the porcine anterior segments perfused under constant flow at 0.1 mL/h could bekept in normal range(10～12 mmHg). The IOP was elevated with the increasing of perfusion rate, while the morphology and structure of the tissue were well preserved. TM cultured by TM organ culture could also reserve the tissues well, but the intercelluar spaces collapsed. Conclusion Anterior segment perfusion model could be a short-term high-pressure model and may simulate the normal physical state. Adequate perfusion was necessary for normal TM.
