BACKGROUND: This meta-analysis of randomized controlled trials aimed to systematically evaluate the value of albuterol in the treatment of patients with acute respiratory distress syndrome (ARDS). DATA SOURCES: Randomized controlled trials on albuterol treatment of ARDS from its inception to October 2014 were searched systematically. The databases searched included: PubMed, Ovid EMBASE, Ovid Cochrane, CNKI, WANFANG and VIP. The trials were screened according to the pre-designed inclusion and exclusion criteria. We performed a systematic review and meta-analysis of the randomized controlled trials (RCTs) on albuterol treatment, attempting to improve outcomes, i.e. lowering the 28-day mortality and ventilator-free days. RESULTS: Three RCTs involving 646 patients met the inclusion criteria. There was no significant decrease in the 28-day mortality (risk difference=0.09;P=0.07,P for heterogeneity=0.22, I2=33％). The ventilator-free days and organ failure-free days were significantly lower in the patients who received albuterol (mean difference=-2.20;P<0.001,P for heterogeneity=0.49,I2=0％ and mean difference=-1.71,P<0.001,P for heterogeneity=0.60,I2=0％). CONCLUSIONS: Current evidences indicate that treatment with albuterol in the early course of ARDS was not effective in increasing the survival, but significantly decreasing the ventilator-free days and organ failure-free days. Owing to the limited number of included trails, strong recommendations cannot be made.

OBJECTIVETo investigate the feasibility and clinical application value of selecting viable spermatozoa by noncontact diode laser.

METHODSWe obtained immotile spermatozoa from 2 infertile men with obstructive azoospermia or severe asthenospermia and selected viable spermatozoa using a single laser shot at the sperm tail. Those that responded to the laser shot by a curling reaction of the tail were regarded as presumably viable and used for intracytoplasmic sperm injection (ICSI).

RESULTSThe mean fertilization rate was 88.89% after ICSI with the laser-selected viable spermatozoa. Both of the embryo transfers resulted in a single pregnancy.

CONCLUSIONNoncontact diode laser is a useful alternative for the assessment of sperm viability, which may help to achieve successful pregnancy.

OBJECTIVE: To explore alcohol pharmacokinetics as well as acetaldehyde level in peripheral blood in human subjects with different ALDH2 genotypes after drinking. METHODS: Venous blood samples of 14 unrelated volunteers were collected. Polymerase chain reaction-restriction fragment length polymorphism technology was adopted for DNA extraction and ALDH2 genotyping. The volunteers were asked to drink beer at certain doses. The concentration of alcohol and acetaldehyde were assayed by headspace gas chromatography method at different time. The pharmacokinetic parameters were calculated. RESULTS: According to the results of electrophoresis, 5 people carried ALDH2*1/*1 as wild group and 9 people carried ALDH2*1/*2 as mutation group. The good linear range of alcohol and acetaldehyde were 0-1 570.7 microg/mL and 0-5.1772 microg/mL, respectively. The AUC values of alcohol and acetaldehyde and the t1/2Z value of alcohol were higher in the mutation group than that in the wild group. But the CL/F value of alcohol was lower in the mutation group than that in the wild group (P<0.05). CONCLUSION After the consumption of alcohol, alcohol and acetaldehyde metabolism in blood slow down in ALDH2*1/*2 mutation group influenced by the inhibition of enzyme activity, leading to the accumulation of acetaldehyde in peripheral blood, thus reinforcing their effects in the body.

OBJECTIVETo explore the effects of different fertilization methods on the outcomes of elective blastocyst culture.

METHODSWe retrospectively analyzed the outcomes of elective blastocyst culture for 1 153 cycles of IVF and 205 cycles of ICSI performed between january 2009 and December 2012.

RESULTSA total number of 14 748 embryos in the IVF group and 2 655 embryos in the ICSI group underwent sequential blastocyst culture, with 7 871 blastocysts formed in the former and 1 210 in the latter. No cycles were canceled for no blastocyst formation in either of the two groups. The rates of quality embryos, blastocyst formation and embryo utilization were significantly higher in the IVF than in the ICSI group (64.77 vs 58.72%, 53.37 vs 45.57%, and 60.06 vs 52.17%, all P < 0.05), but the rates of implantation, clinical pregnancy and abortion showed no significant differences between the two groups (48.94 vs 51.43%, 49.03 vs 52.02%, and 11.69% vs 15.56, all P > 0.05).

CONCLUSIONWith the same inclusion criteria of selective blastocyst culture, IVF has a lower risk of cycle cancellation due to no blastocyst formation and therefore may effect higher rates of blastocyst formation and embryo utilization than ICSI. Our study suggested that appropriate inclusion criteria of selective blastocyst culture should be laid down according to different fertilization methods.

Objective·To analyze the basic medical insurance policies for children in Shanghai in 2011 and 2017, and compare with those of the other three municipalities to understand the basic medical security status of children in four municipalities in China and analyze the existing problems. Methods?·?The current effective children's basic medical insurance policies and child critical illness insurance policies and related insurance systems in four municipalities were collected systematically. The types of basic medical insurance for children in various municipalities and their funding standards, their own expenses and the proportion of government subsidies, the proportion of outpatient emergency payoff lines and reimbursement at all levels of medical institutions, and the coverage and coverage of major illness insurance reimbursement were collected and compared mainly. Results?·?The basic medical insurance for children in Shanghai is a "double insurance" system, which contained children's hospitalization fund and basic medical insurance for urban and rural residents. The basic medical insurance for children in other municipalities mainly consisted of basic medical insurance for urban (rural) residents. Compared with 2011, the level of financing and the reimbursement of the basic medical insurance for urban and rural residents and of the children's hospitalization fund in Shanghai in 2017 was increased. In 2017, the level of financing of basic medical insurance for urban and rural residents in Shanghai was 1?100 yuan, which was slightly lower than that of Beijing medical insurance for urban residents and new rural cooperative medical insurance and was higher than that of basic medical insurance for urban and rural residents in Tianjin and Chongqing, and the individual payment level of Shanghai was the lowest. The hospitalization payoff lines in Shanghai were lower than those of other municipalities. Shanghai's outpatient and inpatient reimbursement levels were higher those of than other municipalities. There wasn't a capping line in Shanghai. There were capping lines in other municipalities. There was a great difference in the insurance policy of the major diseases in four municipalities. Conclusion?·?According to their own actual conditions, models for children's medical care systems that suited each municipalities’ social and economic development have been established. Shanghai children's basic medical insurance basically meets the needs of children's growth but needs improvement in terms of the type and level of medical security for major illnesses.
