Objective Mild hypothermia provides protection for the brain and improves prognosis in the treatment of severe traumatic brain injury, which is widely acknowledged.The article aimed to analysis the prognosis and complications of long-term and short-term mild hypothermia on patients with severe traumatic brain injury. Methods According to the cochrane systematic review methods, thorough search was carried out in databases including Cochrane, Pubmed, Embase, CBM, CNKI, Wanfang and VIP.Eval-uation was made on the quality of selected documents, and Revman5.2 software was applied for meta analysis after data extraction. Results Long-term mild hypothermia achieved improved prognosis compared to short-term mild hypothermia ( GOS score 4 ~5 ) [RR=1.37, 95%CI (1.14, 1.64), P=0.0006].No significant difference was found between these two therapies in pneumonia in-cidence (P=0.94), arrhythmia incidence ( P=0.54) and stress ulcer incidence (P=0.99). Conclusion In comparison to short-term hypothermia therapy, long-term mild hypothermia therapy improved the prognosis of patients with severe traumatic brain inju-ry without obvious increase in the incidence of pneumonia, arrhythmia and stress ulcer.

Objective:To differentiate human embryonic stem cells ( hESCs ) into keratinocytes ( K-hESCs) and analyse the expression characteristics of biomarkers of K-hESCs.Methods: The hESCs of line H9 were seeded on matrigel in mTeSR1 medium.The hESCs were directly differentiated into kerati-nocytes in epithelial differentiation medium with bone morphogenetic protein 4, retinoic acid and N2 sup-plement.The karyotype of K-hESCs was analyzed, comparing the gene expression differences of K-hESCs with human gingival epithelial cells (HGECs), human immortalized oral epithelial cells (HIOECs) and HaCaT by Real-time PCR.Molecular characteristics of the cell differentiation were observed throughout the process by immunocytochemical techniques.Results:H9-hESCs were successfully differentiated into the cells that exhibited characteristics of keratinocytes in epithelial differentiation medium.The karyotype of K-hESCs was 46, XX; and the keratinocyte gene p63 expression in K-hESCs was significantly lower than that in HaCaT ( P<0.05) , but there was no significant difference of p63 expression in K-hESCs, comparing with that in HGECs and HIOECs ( P >0.05 ) .Conclusion: H9-hESCs could be directly differentiated into K-hESCs.The gene expression of K-hESCs was similar to that of epithelial cells in the early stage of monolayer cells differentiation with high proliferative activity.

Objective: To investigate the changes of peripheral cardiotrophin-1 (CT-1) and brain natriuretic peptide (BNP) concentrations in patients undergoing off-pump coronary artery bypass grafting (OPCABC), and the clinical significance of peripheral CT-1 and BNP in cardiac surgery thereof. Methods:Fifty elective OPCABG patients were included in the study. The concentrations of CT-l and BNP were measured before surgery, and at 6 hours, 72 hours, 1 week and 10 months after the operation respectively. The clinical data of the heart function were also collected in patients . Results:(1 )The peripheral CT-1 levels were significantly higher at 10 months after OPCABC than those before operation. (2 )The concentration of peripheral BNP increased at 6 hours after operation. The peak level was found at 72 hours, and remained higher level until the 1 week after operation. The BNP concentration was returned to the normal level at 10 months after OPCABG. (3 )The baseline levels of CT-1 and BNP were both positively correlated with NYHA rank and the diameter of the left ventricular end-diastolic dimension (LVEED), but negatively correlated with left ventricular ejection fraction (LVEF). However, no correlations were found between CT-1 and BNP and NYHA rank, LVEF or LVEED at 10 months after OPCAB. Conclusion:The perioperative blood BNP levels were increased significantly by OPCABG, while perioperative level of CT-1 increased slowly compared with that of BNP. In cardiac surgery,perioperative concentrations of CT-1 and BNP may reflect the cardiac function in patients before OPCABG. The further studies are warranted to assess the prognosis.

OBJECTIVETo investigate human papilloma virus (HPV) infection and typing in 7 640 cases of women in Shanxi province in order to provide theoretical basis for the prevention and treatment of the cervical cancer.

METHODSTotally, 7 640 cases of cervical cell specimens in Shanxi provincial tumor hospital, screening and physical examination from 2012 January to 2013 May and 23 HPV genotypes were analyzed by PCR and reverse dot blot gene chip technology.

RESULTSA total of 1 441 cases of patients with HPV infection were to be found in 7 640 cases of women with an average age of (42.26 ± 19.15)years old. The total infection positive rate, infection rate of high-risk HPV, infection rate of low-risk HPV and infection rate of mixed high and low risk were 18.86% (1 441/7 640), 16.03% (1 225/7 640, including multiple high-risk of HPV infection), 4.88% (373/7 640, including multiple low-risk of HPV infection) and 2.05% (157/7 640) respectively. The rate of high-risk HPV infection was 85.01% (1 225/1 441) in total infection positive women. The most common subtype was HPV16 (34.70%, 523/1 507) and followed by HPV58 (11.48%, 173/1 507), HPV18 (7.43%, 112/1 507), HPV33 (7.10%, 107/1 507), HPV56 (6.04%, 91/1 507) and HPV52 (5.51%, 83/1 507) respectively in tested 18 high-risk HPV subtypes, and there was no HPV82. The most common subtype was HPV43 (38.13%, 151/396) and followed by HPV42 (22.22%, 88/396), HPV81 (20.45%, 81/396), HPV6 (11.87%, 47/396) and HPV11 (7.32%, 29/396) respectively in tested 5 low-risk HPV subtypes. The HPV infection positive rates were significantly different in different age groups and HPV total infection rate, high-risk infection rate in 41-50 year-old age group was the highest, 23.23%. The infection rates of single subtype of HPV and single high-risk subtype of HPV were 75.71% (1 091/1 441) and 61.35% (884/1 441) respectively in all cases of infection women and single high-risk subtype infection rate was 81.03% (884/1 091) in all cases of single subtype infection women. The infection rate of multiple subtype of HPV was 24.29% (350/1 441) in all cases with HPV infection. The double infections was most common (18.18%, 262/1 441) in which the women of double high-risk infections of HPV were 151 cases (10.48%, 151/1 441). The rates of double infection, triple infection and quadruple or more infection of HPV were 74.86% (262/350), 20.29% (71/350) and 4.89% (17/350) respectively in all cases with HPV multiple infection. The positive rates of HPV infection in different age groups were obvious difference. The positive rate of single infection of HPV was 17.80% (574/3 224) in cases of 41-50 years old group which higher than that in other groups(χ² = 20.18, P < 0.05).

CONCLUSIONThe more common high-risk HPV subtype is HPV16, HPV58, HPV18, HPV33, HPV56 and HPV52 and low-risk HPV subtype is HPV43, HPV42 in Shanxi province. HPV infection is most common in the age group of 41- 50 years old female.
