AIM: To investigate the effect of erigeron on intercellular adhesion molecule-1 (ICAM-1) and mRNA expression during cerebral ischemia/reperfusion. METHODS: The rat models of middle cerebral artery (MCA) focal cerebral ischemic reperfusion were established with the suture method in the study. The ICAM-1 mRNA and protein expression were measured by RT-PCR and immunohistochemistry techniques, respectively. RESULTS: By down-regulating the expression of ICAM-1 protein and mRNA and alleviating inflammation in cerebral ischemic region, erigeron exerted a protective effect in cerebral ischemia and reperfusion. CONCLUSION: The results suggest that erigeron protects the brain against cerebral ischemia and reperfusion injury via inhibiting ICAM-1 expression. [

Objective To make recommendations on the development of private hospitals,by means of investigation and analysis of their business operations.Methods Quantitative and descriptive analysis were used to study business operation data from 2011 to 2013 of the 172 private hospitals,in order to learn their present status and development trends.These data were compared with public hospitals in average to identify problems.Results The revenue and expenditure of theses private hospitals increased at a fast pace,with a revenue growth rate of 22.0% and an expenditure growth rate of 15.7% in 2013.Number of visits gradually improved,with an increase of 12.9%.But the rate of bed occupancy was only 68.1%,lower than the average of public hospitals.Conclusions In view of the low resource utilization,the authors recommend such hospitals to improve hospital management systems,and uphold the integrity of business,so as to compete with public hospitals differentially.

Objective To detect TCRγ gene rearrangements in skin lesions and peripheral blood of patients with parapsoriasis, and to study their clinical significance. Methods Totally, 20 patients with parapsoriasis were included in this study. BIOMED?2 multiplex PCR was performed to detect TCRγgene rearrangements in lesional skin (n=20)and peripheral blood(n=11)samples from the patients with parapsoriasis. Statistical analysis was performed to assess the relationship of TCRγ gene rearrangements with clinical types of parapsoriasis as well as general information and histopathological manifestations(including non?specific manifestations and atypical manifestations)of patients. Results TCRγ gene rearrangements were positive in lesional skin from 7 of the 20 patients, in peripheral blood from 3 of 11 patients, and in both lesional skin and peripheral blood from 2 patients. Positive TCRγ gene rearrangements in skin lesions were significantly correlated with mycosis fungoides(MF)?related atypical histopatho?logical manifestations(P<0.05), but those in neither skin lesions nor peripheral blood were correlated with gender and age of patients or clinical course and types of parapsoriasis(all P>0.05). During an average follow?up time of 44.85 ± 18.48 months, 1 case progressed into MF, and 2 were cured. Conclusions Positive TCRγgene rearrangements in skin lesions of patients with parapsoriasis may be correlated with MF?related atypical manifestations. The presence of TCRγgene rearrangements and atypical histopathological manifestations may suggest the possibility of progression from parapsoriasis into MF.

The article presented the drugs supply management mode reform in place since 2009 in the one district of Shanghai.Authors analyzed and commented the implementation and outcomes,and studied the potentials of successful promotion nationwide.They hold that such a mode works to some extent in terms of reducing management costs of medical institutions,lowering drug purchase price,encouraging rational drug use of such institutions,and reforming the compensation manner for medical institutions.This mode,however,calls for an operating environment in need of not only funding support,but also new concepts and economic development strength of the society as a whole.This means that such a mode is only recommended in developed areas in China.

Objective To understand the clinical characteristics during clinical diagnose and treatment of young women patients under 35 years with cervical cancer. Methods The clinical data of 95 cervical cancer patients under 35 years was reviewed and analysed retrospectively. Results The percentage of the patients at this age set was 18. 59% ,accounting for almost one fifth of all the same period patients with cervical cancer. The most common primary clinical representation was sexual bleeding of vigina (90.53% ,86/95) ;28 cases (29. 47%, 28/95) were misdiagnosed by naked eye examination and local treated as cervicitis; 13 cases (13. 68%, 13/95) with severe pathological changes were missed diagnosed by biopsy under colposcopy ;53 cases (55. 79% ,53/95) had their ovary preserved by one or two and had no metastasis or recurrence with carcinoma. Conclusions Sexual intercourse bleeding is the most common manifestation of young women with cervical cancer,which demands more attention. The biopsy under colopscopy has certain limitations,and should be performed along with conization while necessary. It is safe and feasible to retain ovary in cervical cancer patients before Ⅱ stage.
