Objective To explore the association between maternal methylene tetrahydrofolate reductase (MTHFR) C677T polymorphism and neural tube defects (NTDs). Methods CBM, VIP, CNKI, Wanfang, PubMed and Web of Science databases from set up to March, 2014 were electronically searched to identify case-control studies on the relationship between maternal MTHFR C677T polymorphism and NTDs. The data were quantitatively analyzed by RevMan 5.0 software. Results A total of 25 studies were selected including 2 282 cases and 3 420 controls. Overall, the pooled OR (with 95%CI) under co-dominant model and allele contrast were 2.28(1.60-3.24), 1.25(1.02-1.53) and 1.42(1.21-1.67). Subgroup analysis showed significant association between maternal MTHFR C677T polymorphism and NTDs susceptibility in Asian populations. Conclusion The present meta-analysis suggests that MTHFR C677T polymorphism is significantly associated with maternal risk for NTDs, especially in Asian populations.

To screen and identify the possible pathogen of the firstly confirmed human case of avian influenza A in Beijing, the throat swabs and tracheal aspirates of this case were collected and the H5N1 viral nucleotide was tested with real time RT-PCR. The certification of result, screening of other pathogens in respiratory tract and sub-typing of influenza viruses were made by using re-sequencing microarray. It was found that the H5N1 viral nucleic acid was positive in the tracheal aspirate of this case by means of detection with real time RT-PCR and the specific sequence of the non-structural protein (NS) gene of H5N1 virus was obtained through the detection with re-sequencing clip. Through the comparative study with the sequence in Genbank, it was proved to be the H5N1 nucleic acid of avian influenza viruses and excluded the possibility of infections with 30 subtypes of influenza viruses and 33 other respiratory tract pathogens. It is apparent that the pathogen detection with re-sequencing clip shows the high sensitivity and specificity and it plays an important role in the pathogen screening and identification for the firstly confirmed human case of avian influenza A in Beijing.

Objective To evaluate the impact of early enteral nutrition (EEN) compared with parenteral nutrition (PN) on patients after hepatectomy. Methods Seventy-eight patients undergoing liver resection were randomized prospectively into two groups: EEN group receiving early enteral nutrition (n=35) and PN group receiving parenteral nutrition (n=43). The patients in both groups received isocaloric and isonitrogenous nutritional formulas 24 h after operation and the formulas were stopped on postoperative day 7. The general conditions, liver function tests, clinical complications,and clinical nutritional variables at three time points that included preoperative phase, postoperative day 1 (POD 1) and postoperative day 8 (POD 8) were observed. Results No significant differences were found in length of hospital stay, liver function and clinical nutritional variables between the 2 groups. In the EEN group, the serum prealbumin level almost returned to the preoperative level on POD 8. The nutritional complication rate of the EEN group was increased significantly but it was milder than that of the PN group. The time of gut function recovery in the EEN group was shorter than that of the PN group. The costs of nutritional drugs showed a significant decrease in the EEN group.Conclusion Early enteral nutrition is safe, rational and effective in patients who have undergone hepatectomy. Early enteral nutrition is better than parenteral nutrition in promoting liver function recovery, liver protein synthesis, postoperative recovery of gut function and decreasing costs of nutritional drugs.

Objective To comparing the diagnostic and therapeutic strategies for patients with benign prostatic hyperplasia(BPH) between doctors in general hospitals and community hospitals,and to provide scientific clues for the standardization in medical practice.Methods General and community hospitals in urban China were selected via the stratified sampling.127,325 outpatients in these hospitals from December 2011 to December 2012 were randomly recruited.Results The average age of patients was(67.82±8.62) years.There were significant differences in I-PSS,prostate volume,urinary flow rate(UFR) and result of digital rectal examination(DRE) between patients in general and community hospitals.The rates of diagnostic applications were different between doctors in the two kinds of hospitals except I-PSS.Compared with community hospitals,DRE was more frequently applied while ultrasonic inspection and UFR test were less used in general hospitals in North China.A totally opposite situation was observed in East China as compared with the north.The application rates of DRE and UFR test were lower and ultrasonic inspection rate was higher in community hospitals than in general hospitals in South China.Pharmacotherapy was the most common treatment for BPH patients in both types of hospitals(97.53 ％).The rates of drug combinations were statistically different but both were close to 75％ in the two types of hospitals.In community hospitals,the percentage of patients receiving watchful waiting with severe symptoms and signs were lower than that of patients receiving watchful waiting with moderate symptoms and signs,but the percentage of patients receiving operation was not significantly increased.On the contrary,the percentage of patients receiving operation with severe symptoms and signs was higher than that of patients receiving operation with moderate symptoms and signs in general hospitals,but the percentage of patients receiving watchful waiting was not decreased.Conclusions Applications of diagnostic methods are significantly different between doctors in general hospitals and community hospitals and vary among regions.Therapeutic strategies are correlated with the severity of obstructive symptoms or signs.The medication strategy is similar between the two types of doctors.

Objective To observe the effects of rosuvastatin on the homocysteine (Hcy)-induced expression of matrix metalloproteinase 2 (MMP 2) and cell migration in rat vascular smooth muscle cells (VSMCs), and to explore the possible mechanism of Hcy-induced atherosclerosis and the role of statins in reversing atherosclerosis. Methods In one cell culture plate, the cultured rat VSMCs were incubated with different concentrations of Hcy (0, 50, 100, 500, 1000 μmol/L and 5000 μmol/L) in vitro for 24 h, 48 h and 72 h. And in another cell culture plate, the different concentrations of rosuvastatin (10-9, 10-8, 10-7, 10-6, 10-5 mol/L and 0 mol/L) were added to the cultured rat VSMCs (while the concentration of Hcy was 1000 μmol/L). The MMP 2 expression and enzyme activity were determined by gelatin zymography and Western blotting. The effects of Hcy and rosuvastatin on cell migration and invasiveness of VSMCs were observed. Results Hcy (50-5000 μmol/L) increased the protein expression, and Hcy (50-1000 μmol/L) increased enzyme activity of MMP 2 significantly. But Hcy (5000 μmol/L) inhibited activity of MMP 2 (F=9.31, 6.44 and 5.97, all P＜0.05). Rosuvastatin (10-9-10-5 mol/L) inhibited Hcy-induced expression and enzyme activity increasing of MMP 2. The counts of cell migration of VSMCs were 18.32±2.17, 32.68±4.34, 44.75±4.08, 61.39±5.21, 79.74±5.54 and 90.78±5.83, while the concentration of Hcy was 0, 50, 100, 500, 1000 μmol/L and 5000 μmol/L respectively (F=5.31, P＜0.05). The counts of cell migration of VSMCs were 79.74±5.54, 62.53±6.41, 48.37±5.66, 31.41±4.79, 19.27±3.62 and 11.17±2.33, while the concentration of rosuvastatin was 10-9, 10-8, 10-7, 10-6 and 10-5 mol/L respectively (F=4.99, P＜0.05). Rosuvastatin could decrease the stimulation of Hcy-induced migration of VSMCs. Conclusions Hcy can influence the MMP 2 protein expression/activity in VSMCs, and rosuvastatin can inhibit augmentation of Hcy-induced MMP 2 expression/activity and migration of VSMCs. It may be one of the multiple-effects of rosuvastatin reducing atherosclerosis.
