Objective The relationship between the clinicopathological features and the prognosis of breast cancer patients was evaluated by the expression of EPB41L4A-AS2 in breast cancer tissues.Methods The relationship between the expression of EPB41L4A-AS2 and the clinical features of breast cancer was evaluated by using the genome meta analysis,TCGA and Gene Expression Library(GEO) datasets.The correlation between EPB41L4A-AS2 and apoptotic pathway was verified by Western blotting.Results The results from Meta -analysis,TCGA and GEO datasets showed that EPB41L4A-AS2 was low in breast cancer tissues and was positively correlated with poor clinical and pathological features.EPB41L4A-AS2 was confirmed an association with the classical apoptosis pathway in breast cancer cell lines.In the meta-analysis of GEO,we found the high expression of EPB41L4A-AS2 with good prognosis.Conclusion EPB41L4A-AS2 inhibits tumor formation and has a high value in clinical prognosis of breast cancer.

Objective To detect the salivary levels of IgA,alpha-amylase and acetylcholinesterase (AChE) and saliva flow rates of IgA in normal controls versus Parkinson disease (PD) patients,and to analyze the correlation of these salivary biochemical indexes with disease duration,H&Y rating scale,SCOPA-AUT score,sialorrhea score,dry mouth score and the use of levodopa.Methods Thirty-eight PD patients including twenty-two patients treated with levodopa,and twenty-one normal controls were selected in our study.About 3 ml saliva was collected from each subject.Salivary IgA was detected by immunoturbidimetry.Alpha-amylase and AChE were tested by enzymatic colorimetry.The protein concentration was analyzed by BCA kit to normalize ACHE.The salivary flow rate and IgA flow rate were also calculated.Results Salivary flow rate (ml/min) was (0.39±0.22) in normal controls,and (0.35±0.28) in PD groups;the level of IgA (mg/L) was (148.3±86.1) in normal controls,and (183.7±126.3) in PD groups;IgA flow rate (μg/min) was (47.8±25.9) in normal controls,and (46.9±27.1) in PD groups;the level of alpha-amylase (U/L) was (1.63 ± 1.21) × 105 in normal control,and (1.35 ± 9.87) × 105 U/L in PD group;and the level of AChE (U/mg) was (0.12±0.08) in normal controls,and (0.09±0.05) in PD group.No statistically significant differences in above indexes were found between PD group and controls.There were negative correlations between salivary flow rate and dry mouth score (r =-0.445,P =0.005) and between alpha-amylase concentration and sialorrhea score (r=-0.327,P=0.045).The positive associations were found between IgA concentration and the SCOPA-AUT score (r =0.438,P =0.006),and between IgA flow rate and sialorrhea score (r =0.411,P =0.01).Conclusions Salivary flow rate and level of alpha-amylases tend to be decreased in PD patients,while IgA concentration has an upward tendency.Salivary alpha-amylases concentration and IgA flow rate are correlated with the symptom of sialorrhea,while IgA concentration correlates with the degree of autonomic symptoms.These measurements can be used as indexes for evaluating the lesions of the autonomic nervous system.

Splenic cyst is clinically rare.It can be classified as either true or false.Ultrasound,CT and MRI scan are helpful in diagnosing splenic cyst.Indication for a treatment depends mainly on clinical symptoms and diameter of the cyst.Now,there is a more conservative attitude on splenic surgery and the patient should be offered laparoscopic approach.Both nonoperatively treated patients and surgically treated patients should be given ultrasound examination regularly,in order to check the cyst size and exclude reappearance.

Objective A meta-analysis was conducted to figure out the effects of anesthetic methods on postoperative myocardial infarction in noncardiac surgery patients.Methods We searched PubMed, Embase, Ovid, Cochrane Library, Google scholar, CNKI, Wang-fang data and VIP Database (by September 2016) to identify relevant studies that focused on the effect of intrathecal blockade on postoperative myocardial infarction and mortality in non-cardiac surgery.Meta-analysis was performed using software of RevMan 5.3.Results A total of 21 859 patients from 10 RCTs were enrolled.The meta-analysis showed that there were no differences in myocardial infarction within 7 postoperative days (OR=0.44, 95%CI 0.13-1.46, P=0.18) or 30 days (OR=1.49, 95%CI 0.89-2.49, P=0.13) and all-cause mortality (OR=1.26, 95%CI 0.84-1.88, P=0.26) between epidural anesthesia combined with general anesthesia and general anesthesia.Furthermore, there were no differences in myocardial infarction within postoperative 7 days (OR=1.14, 95%CI 0.31-4.17, P=0.84) and all-cause mortality within postoperative 30 days (OR=0.88, 95%CI 0.43-1.79, P=0.73) between spinal anesthesia alone and general anesthesia alone.Conclusion Intrathecal blockade cannot affect the incidence of myocardial infarction and mortality in high-risk cardiac patients undergoing intermediate or high-risk non-cardiac surgery.

Objective To explore the efficacy and safety of transcatheter intra-arterial hyperthermo-chemotherapy for advanced ovarian carcinoma. Methods 36 patients with unresectable or recurred ovarian carcinoma were divided into two groups randomly: treatment group(n=20) and control group(n=16). Transcatheter intra-arterial infusion warmed to 62 degree chemo-agents via the ovarian tumor supplied artery was performed in the treatment group while routine intraarterial chemotherapy was done in the control group. The CA125 level dynamic change, short-term efficacy and side effect after the interventional procedure were compared between two groups.Results The CA125 level decreased significantly in the treatment group more than that in the control group(?

Objective To understand hand hygiene(HH) among health care workers(HCWs) in primary medical institutions in Shijiazhuang,and evaluate HH compliance,so as to formulate the strategy for HH management.Methods In 2015,one county-level comprehensive medical institution and two township medical institutions from each of seven counties of Shijiazhuang city were randomly selected,HH qualified rates of HCWs in all divisions of internal medicine before clinical procedures and after HH were analyzed statistically.Results 118 HCWs before clinical procedures and 130 HCWs after HH were monitored.The qualified rate of HH of physicians and nurses before clinical procedures were 44.26％ (27/61) and 40.35％ (23/57) respectively;HH qualified rate of nurses in township hospitals before clinical procedures were higher than county-level hospitals(x2 =6.447,P =0.011);the qualified rate of HH of physicians and nurses after HH were 98.41 ％ (62/63) and 98.51 ％ (66/67) respectively;there were significant differences in the qualified rates before clinical procedures as well as after HH in HCWs at different levels and types of medical institutions(all P＜0.05).Conclusion The qualified rate of HH among HCWs in primary medical institutions in Shijiazhuang before clinical procedures is low,medical institutions should improve the HH compliance among HCWs from various aspects.

Objective To understand the house-dust mite fauna in the school dormitory in Guangzhou city.Methods With the direct smear method and saturation solution of NaCl floatation method,a total of 970 bed-dust samples collected from the five school dormitory buildings were examined,from Oct.to Dec.in 2006.The house-dust mite in the samples were counted and classified.Results The prevalence rate of mite was 98.76%.About 72% of the samples,the number of mites was 500 and 3 000/g dust.Mean number of the mites in bed-dust samples showed a significant difference between the male and female student dormitory,and among five dormitory buildings.The mean number of mites usually decreased as the floor increased.Dermatophagoides pteronyssinus,Dermatophagoides farinae,gamasid mites,scab mites and pyemotidae etc were found in the samples.Conclusion House-dust mites universally exist in bed-dust of the school dormitory in Guangzhou city and the number is larger.Dermatophagoides pteronyssinus,Dermatophagoides farinae are the dominant kinds among the mites.
