Objective To observe the clinical effects of prostaglandin E1 on liver cirrhosis patients and evaluate its security. Methods 68 cases with liver cirrhosis admitted in Luqiao hospital were randomly divided into experimental group(34 cases)and control group(34 cases)equally. Patients in control group were received normal therapy,while in experimental group were added prostaglandin E1 on basis of normal therapy. The efficacy and adverse reactions were observed and compared. Results Compared with before treatment,the average value of albumin in two groups were increased obviously,which in experimental group from (27.9 ±4.1)g/L to (36.5 ±4.3)g/L,control group from (27.8 ±4.0)g/L to (31.7 ±4.2)g/L,the differences were significant(P<0.05 ),and the difference between two groups was significant(P<0.05 ),too. The content of alanine aminotransferase and aspartase aminotransferase in two groups were decreased significantly(P<0.05 ),and experimental group was more lower than control group(P<0.05 ). The number of effcacy in experimental group was 28 and account for 82.35%,while in control group was 1 1 and account for 32.35%,the difference was significant(P<0.05). Conclusion Prostaglandin E1 can improve liver function,and has good clinical effects and high security in treatment with liver cirrhosis patients.

BACKGROUND:Fractures of shafts of the tibia and fibula are the most common diaphyseal fractures among al long bones. The clinical significance of fibula fixation in treatment of distal third shaft fractures is controversial, and the studies are also different. OBJECTIVE:To explore the clinical significance of fibular fixation in treatment of distal third tibia shaft fractures. METHODS:A retrospective review has been performed on the clinical data of sixty-four cases with distal third tibia shaft fracture in Department of Orthopedics, China National Offshore Oil Corporation General Hospital from January 2006 to March 2010. Al cases were divided into two groups based on whether the fibula was fixed or not: fibula fixation group (n=36) and fibula non-fixation group (n=28). Union rate of fracture, bone union time and tibial valgus angle were compared between the two groups. According to Merchant-Dietz criteria, the ankle range of motion and ankle evaluation score were evaluated and compared between the two groups. RESULTS AND CONCLUSION: No significant difference in union rate of fracture, bone union time and ankle range of motion was detected between two groups. Tibial valgus angle was smaler in the fibula fixation group (5.42±1.16)° than in the fibula non-fixation group (7.54±1.90)°(P=0.006). Ankle function score was higher in the fibula fixation group (93.58±0.97) than in the fibula non-fixation group (90.57±3.92) (P=0.000). Three cases in the fibula fixation group suffered from superficial wound infection, and achieved good healing after treatment of anti-infection and changing dresses. Above results verify that fibular fixation can reduce tibial valgus angle and improve ankle joint function in treatment of distal third tibia fractures.

Recently,the detection of circulating tumor cells(CTCs)in peripheral blood is used in clinical practice as a form of‘ liquid biopsy’. The self-seeding mechanism of CTCs provides a novel approach to explore the growing mechanism of malignant tumor and developing corresponding targeting therapies. A decade ago,the CellSearch system, which can capture and enumerate CTCs,has been validated by Food and Drug Administration( FDA)as an aid for monitoring the relapse of tumor after radical operation in patients with breast,prostate and colorectal cancer. In recent years,although the separation and detection technique of CTCs has been promoted significantly,the clinical significance of CTCs in tumors of digestive system is still under investigation. This article reviewed the research progress of peripheral blood CTCs in digestive system tumors.

Objective To systematic evaluate the prevalence of secondhand smoke among Chinese mainland rural residents by meta?analysis,so as to provide reference for making relevant smoking control regulations and the carry out of targeted tobacco control action. Methods The related stud?ies were searched and collected from PubMed,CNKI,Wanfangdata,VIP and CBM database,which were published between 2001 and 2015 about the prevalence of secondhand smoke among Chinese mainland rural residents. Meta?analysis was tested by software CMA V2. Results The pooled prevalence of secondhand smoke among Chinese mainland rural residents was 46.6%(95%CI 40.5%?52.8%). Stratified analysis showed that the prevalence of secondhand smoke were 45.7%and 47.5%for male and female,45.7%and 51.1%for eastern and midwest China,22.1%、34.2%and 71.3%for public place,workplace and family,respectively. The prevalence among sex,regions,and places were statistically significant. Conclusion The prevalence of secondhand smoke among Chinese mainland rural residents was relatively high,and the prevalence of secondhand smoke was higher in women than in men,in midwest area than in eastern area,and at family than at public place and at workplace.

Objective To compare and determine the reproducibility of apparent diffusion coefficient (ADC)values of the normal liver parenchyma in respiratory-triggered,breath-hold,and free-breathing diffusion weighted magnetic resonance imaging (DWI). Methods 11 volunteers did three times of breath-hold (excitation number is 1,at the end of the expiration,thickness/gapping=5 mm/1 mm), respiratory-triggered (excitation number is 2,at the end of the expiration,thickness/gapping=5 mm/1 mm),free-breathing (excitation number is 4,thickness/gapping=5 mm/1 mm)and for a total of nine axial liver DWI,the gradient factor was 800 s/mm2 .Then they were all coronally reconstructed (thickness/gapping=8 mm/1 mm).The nonparametric test was used to compare all axial and coronally reconstructed liver ADC values;and the Bland-Altman method was used to evaluate the ADC values’repeatability in coronally reconstructed images.Results The breath-hold DWI’s mean ADC value was (1.09±0.07)×10-3 mm2/s significantly lower than the respiratory-triggered DWI(1.16± 0.09)×10-3 mm2/s and the free-breathing DWI(1.19±0.10)×10-3 mm2/s(P<0.005),the axial and coronal images’results were similar.The ADC values’average difference and scope of consistency of coronal image were (-0.09 to -0.01±0.09 to 0.48)for breath-hold DWI,(-0.04 to 0.01±0.11 to 0.17)for respiratory-triggered DWI,(-0.07 to -0.02±0.11 to 0.18)for free-breathing DWI,respectively.Conclusion The breath-hold DWI’s ADC value of normal liver parenchyma is lower than the respiratory-triggered and free-breathing DWI,and showed more poorer repeatability.It is suggested that the measurement of ADC values of the liver parenchyma should be done within the respiratory-triggered or free-breathing DWI.
