Achalasia is a primary esophageal motility disorder, with the main symptom of dysphagia; and caused by the tonus increase and abnormal relaxation of the lower esophageal sphincter(LES). The etiology remains unclear, the objective of the current treatment approaches for achalasia containing the reduction of the LES tone and obstruction to relieve the patients' symptoms; including pharmacologic treatment, botulinum toxin treatment, surgical myotomy, pneumatic dilatation and cardia stent dilatation. The temporary cardia stent dilatation possesses some better advantages and effects; and ought to be the first choice of minimal invasive interventional management for achalasia.

Objective:To investigate the changes of humoral and cellular immunity markers in various liver disease by ABO blood group,the reliable evidences were provided.Methods:The cases of 500 health men (NC) as contrals,various acute and chronic liver disease with the positive index of hepatitis B which include acute hepatitis (ASC) 140 cases,chronic hepatitis (CH) 192 cases,post-hepatitis cirrhosis (LC) 160 cases,primary hepatocellular carcinoma (PHC) 70 cases were examined by immune-spresding assay,APAAP immune-bridge assay and so on in the study,the changes of serumal IgG,IgM,IgA,IgD,Ige,complement C_3(C_3),total complment (CH50),circulatory,immune complex (CIC),E-rosetter formation rate (E-RFC) and T-lymphocyte subsets in the group of NC,ASC,CH,LC and PHC were investigated respectively. Results:Compared to contrals,the humoral immune markers of all groups of liver disease changed markedly,Ige increased changed apparently and IgG increased.Secondly from ASC,CH,LC, to PHC,mean while,C_3 and CIC increased obviously and E-RFC decreased obviously in the group of PHC.Compared to the group of other blood type incresed markedly (P

Objective To evaluate the necessity and feasibility of nucleic acid test for donors blood screening .Methods From July 1 ,2011 to December 31 ,2014 ,a total of 170 316 blood samples which were negative in enzyme-linked immunosorbent assay (ELISA)and qualified in aianine aminotransferase detection ,were selected in this study stochastically .All the samples were detected hepatitis B virus(HBV) ,hepatitis C virus(HCV) ,human immunodeficiency virus(HIV) by nucleic acid amplification technology (NAT) .NAT positive samples were reconfirmed in National Center for Clinical Laboratories(NCCL) .Results A total of 160 cases of nucleic acid reactive samples were found out ,the total response rate was 0 .09% ,The response rate of Roche nucleic acid detec-tion system was 0 .10% ,response rate of David nucleic acid detection system was 0 .08% ,there was no significant difference be-tween the two methods(P>0 .05) .In 27 cases of specimens ,14 cases were confirmed as HBV DNA positive ,no HCV RNA and HIV RNA were detected ,the confirmed positive rate was 51 .85% .There were 2 samples detected by chemiluminescence HBsAg reactivity .Conclusion ELISA screening of blood donors has missing phenomenon ,nucleic acid detection method could be used as an effective supplement of the ELISA ,could improve the safety of blood for clinical use ,detection sensitivity is better than ELISA .

AIM:To investigate the correlation between chronic dry eye and refractive regression after laser in situ keratomileusis (LASIK)for myopia.METHODS:Two hundred and twenty-five eyes of 225 patients were enrolled in this study.Examinations including Schirmer test,tear break-up time(BUT),corneal sensation,and ocular surface staining were performed before and 6 months after LASIK.Dry eye symptoms were assessed using the McMonnies Dry Eye Symptom Survey.Data were analyzed on history and treatment response.RESULTS:Refractive regression after LASIK was related to chronic dry eye.It occurred in 8(25.0%)of 32 patients with chronic dry eye and in 18(9.3%)of 193 patients without dry eye(P＜0.01).CONCLUSION:The risk of refractive regression was increased in patients with chronic dry eye.

Myopia is one of the three main school public health problems in China, the prevalence of which has been showing a rising and low-aging tendency in the past few decades. High myopia can cause several vision -threatening problems such as degenerative retinal conditions, cataracts, retinal detachment, and choroidal neovascularization. Its related complications are the leading causes of visual impairment and blindness, adversely impacting the afflicted individual's quality of life. Therefore, the prevention and control of myopia have become a common concern of family, school and health department. The purpose of this review is to summarize the progression of a variety of intervention methods used to prevent and control childhood myopia in recent years.
