Objective To investigate the molecular epidemiology of GJB2 mutations as a causative effect of prelingual deafness in northwestern China. Methods The medical history of 274 deaf-mute students was collected. Blood samples were obtained from them with informed consent. GJB2 gene sequences of genomic DNAs were amplified by polymerase chain reaction (PCR) with a pair of primers, and bidirectional sequencing of PCR products was performed and analyzed with DNAStar Software. Results A total number of 274 deaf-mute students were diagnosed as non-syndromic hearing impairment, and profound prelingual deafness. Two kinds of polymorphism, seven pathologic mutations and one novel mutation were revealed in the GJB2 screenings of them, and 79G→A and 341A→G were polymorphism with high frequency. Conclusion GJB2 gene mutation is the causative gene in the prelingual deafness with a high incidence of 10.95% in northwestern China. Based on the investigation, it is clear that screening of GJB2 gene mutation should play a significant role in early diagnosis of deaf-mutism in this region.

Objective To explore the clinical features of mitochondrial encephalomyopathy lactic acidosis and strokelike episodes (MELAS) syndrome in fratemal twins brothers.Methods The clinical data,the results of laboratory examinations,electroencephalogram (EEG),imaging,and gene detection,and the process of diagnosis and treatment were retrospectively analyzed the fraternal twin brothers with MELAS syndrome.Results The proband,a 7-year-old male,had intermittent headaches,vomit and twitching at onset.He suffered from exercise intolerance,fatigue,accompanied by short stature and hairy.The fasting blood lactic acid level was increased.Multiple video EEG showed the slowdown of background activity.Head MRI showed recurrent lesions with the characteristics of migration and variation.The point mutation rate of mtDNA A3243G was 34.7%.The diagnosis of MELAS was confirmed.At the same time,his fraternal twin brother was screened and found that his point mutation rate of A3243G was 30.0%.Although there was no clinical symptom at that time,he was onset with convulsion after 3 years.Conclusions Gene detection and family screening are helpful for the early diagnosis of MELAS.The mutation rate of A3243G is very high,which can cause an early onset and serious clinical symptoms.

Objective:To study the relationship between genetic polymorphisms of GSTM1 GSTT1 and the susceptibility of laryngeal and hypopharyngeal carcinomas(LHC).Method:The GSTM1 an GSTT1 genotypes were determined by multiplex PCR analysis in 76 LHC patients and 76 population controls.The association be tween the genotypes and LHC risk was measured by odds ratios(ORs)and 95% confidence intervals(95%Cls).Resuit:The frequency of GSTM1 null genotype was 59.2% in the LHC patients and 42.1% in controls(OR=1.935,95%CI=1.069-3.510),the difference was significant(P<0.01).The frequency of GSTT1 null genotype was 57.9% in the LHC patients and 51.3% in controls.The difference was not significant(P>0.05).In smokers,the risk of the LHC increased in subjects of GSTM1 null genotype(OR=5.545,95%CI=2.158-13.528).Conclusion:GSTM1 polymorphisms are associated with susceptibility to the LHC.It has the synergistic effects with smoking in the development of the LHC.GSTT1 genotypes might have no association with risk of the LHC in urban Linyi.

Objective To understand the risk factors of neurogenic pulmonary edema in the patients with severe hand foot and mouth disease(HFMD). Methods According to neurogenic pulmonary edema or not ,79 patients with severe HFMD were divided into two groups. The difference was analyzed on the clinical symptoms, signs,the outcomes of laboratory and electroencephalogram (EEG) examination between the two groups. Then the risk factors of neurogenic pulmonary edema was analyzed by logistic regression analysis.Results There were significant differences of the EV71 infection rate,high body temperature,myoclonia,limb weakness,the disability of eyeball regulation,tachycardia, hypertension or hypotension, the extension of capillary filling time, leucocytosist, creatine kinase isoenzyme, hyperglycaemia between two groups. However, there were no significant differences of fever, fever time, vomiting, somnolence, convulsion, limb tremor, c-reactive protein and EEG between two groups. Tachycardia, hypertension or hypotension, hyperglycaemia were significant risk factors for neurogenic pulmonary edema by logistic regression analysis. And hyperglycaemia was the most significant prognostic factor(odd ratio 27. 075, P = 0. 000 2). Conclusion Tachycardia, hypertension or hypotension,hyperglycaemia are the significant risk factors for neurogenic pulmonary edema. It is especially important for hyperglycaemia to predict neurogenic pulmonary edema.

Objective To explore the potential association of HLA-A alleles and genetic susceptibility with systemic lupus erythematosus (SLE). Methods Polymerase chain reaction-sequence specific primer (PCR-SSP) was used to analyze the distribution of HLA-A alleles among 106 patients with systemic lupus erythematosus and 122 healthy persons. Results Nineteen out of twenty-four kinds of HLA-A alleles were found from the specimens, including 18 kinds in SLE specimens, and 15 kinds in control specimens. Among them, HLA-A*11 allele was positively associated with SLE (RR = 2.4380, EF = 0.1502, ?2 = 12.2440, P = 0.0005, Pc = 0.0095). For A*01 and A*24, although the P values were less than 0.05, the Pc values were more than 0.05 (0.9462 or 0.2356, respectively). Conclusions The results indicate that HLA-A*11 may be the susceptible allele or may be closely linked with the susceptible genes in Chinese SLE patients.

Objective To explore the feasibility and safety of early ambulation in patients with acute deep ve-nous thrombosis. Methods The literatures about early ambulation for acute venous thrombosis were collected and the quality of the literature was evaluated by two investigators independently. Results Thirteen published studies were recruited for systematic review,including 10 RCTs and 3 CCTs. The meta-analysis showed that compared with bed rest,early ambulation did not increase the incidence of secondary pulmonary embolism in patients with acute DVT[early activity:22/1408;bed rest:34/1417;RR=0.62,95%CI(0.37,1.03),and the incidence of DVT progression [early activity:48/1523;bed rest:45/1525;RR=0.85,95%CI(0.58,1.24)]. There were no statistically significant differ-ences in mortality,swelling,and pain relief in acute DVT patients. Conclusion Early ambulation did not increase the incidence of thrombus progression and secondary pulmonary embolism in patients with acute DVT compared with bed rest. Besides,early ambulation cannot relieve symptoms of swelling and pain in DVT patients. However,it can relieve the acute pain of DVT patients with moderate to severe pain.
