With the development of the molecular biology technic in recent years, the research about the relations between the type of gene mutation and the intelligence growth with the Duchenne muscular dystrophy (DMD) was developed.There are some connections in the intelligence and the type of gene mutation of the children with DMD. The children with DMD have lower intelligence when the mutation is after the 45 exon especially the 63 exon than before the 45 exon. It has more possibility to cause the lower intelligence when the the DMD gene mutation is closer to the end of 3'terminal.

OBJECTIVE To discuss rational layout of Sterilizing and Supply Room in the Department of Stomatology and its scientific utilization of sterilizing equipment which ensure safe medical treatment of patients. METHODS Funds should be invested to the Stomatology Department according to plan and environment and equipment should be transformed. RESULTS Transformed conditions of Sterilizing and Supply Room had conformed to Operation Rules of Sterilization of Dental Medical Instruments in Medical Institutions promulgated by the Ministry of Health.One patient could certainly use his own medical goods with absolute sterilization.This not only reduced opportunities of cross infection,but also protected and made things convenient for medical personnel. CONCLUSIONS The fundamental guarantee of safe medical treatment of patients is rational layout of Sterilizing and Supply Room in the Stomatology Department and rational allocation and scientific utilization of sterilizing equipment.

Congenital cystic lung lesions are a group of congenital lung diseases with low incidence. These include congenital cystic adenomatoid malformation,bronchogenic cyst,congenital lobar emphysema and pulmonary sequestration. These malformations occur during the period of lung development stimulated by various factors. Manifestations of the diseases are very similar,but the pathogenesis and pathology are very different. Congenital cystic adenomatoid malformations are thought to be the results of the cessation of bronchiolar maturation with overgrowth of mesenchymal elements and without development of alveoli. There are 5 pathological types of congenital cystic adenomatoid malformations. Bronchogenic cysts are the results of abnormal budding from a segment of the tracheobronchial tree during embryo development,and the buds with no communication with normal tracheobronchial tree. Congenital lobar emphysema is a term reserved for hyperinflation of alveoli from idiopathic reasons or extrinsic compression,as well as pathological changes of the bronchial wall. Pulmonary sequestrations account for parts of nonfunctioning lung tissue that mostly do not communicate with normal bronchoalveolar tree and vascularized by a systemic artery,two types(intralobar and extralobar sequestration)are described.

Objective: To investigate changes of plasma glucagon level in patients with heart failure (HF) caused by coronary heart disease (CHD) and its clinical significance. Methods: A total of 30 HF patients caused by CHD were selected as HF group, another 30 healthy subjects with corresponding age and gender were regard as normal control group. HF patients received comprehensive therapy of enhancing myocardial contractility, diuretic and vasodilator of 7~10d according to Chinese diagnostic and treatment guideline of chronic heart failure. Changes of glucagon level before and after treatment were observed. Results: Before treatment, plasma level of glucagon in HF group was significantly higher than that of normal control group [(205.67±120.22) ng/L vs. (90.53±20.5) ng/L, P<0.05]. After treatment, plasma level of glucagon [(120.42±30.33) ng/L] significantly decreased than before treatment (P<0.05) in HF group. Conclusion: Plasma glucagon significantly increases in patients with heart failure and gradually decreases to near normal level after treatment. Glucagon level may be regard as one of indexes judging patients’ condition.

Objective To evaluate the curative effect of endoscopic sphincterotomy (EST) combined with laparoscopic cholecystectomy (LC) in the treatment of gallstones complicated with common bile duct stones. Methods A total of 36 cases of gallstones complicated with common bile duct stones were enclosed. First EST was performed to remove the bile duct stones. Then LC was applied to resect the gallbladder. Results EST was successfully performed in 34 cases (94.4%) and failed in 2 cases because of the terminal stricture of the bile duct that was afterwards cured by an open choledochojejunostomy. LC was performed following EST in 34 cases, 32 of which were successful (94.1%) and 2 of which required a conversion to open surgery. Conclusions EST combined with LC is the best way for treating gallstones complicated with common bile duct stones. The biliary stricture mainly accounts for the failure of EST and should be treated by choledochojejunostomy as the first choice.

Objective:To investigate the effect of adenosine (Ado) on the unit discharging electricities in habenula nucleus and on the c-fos expression in lateral habenular complex,and the influence of adenosine on the neuron activities and related gene expression involved in affecting sleep in habenula nucleus and the possible mechanisms.Methods:Intraperitoneal injection,brain flakes pouring of rats,immunohistochemistry and other methods were useel.Results:Ado pouring into flakes of brain depressed the unit discharging electricities of neurons in medial habenular complex(MHb),but obviously increased that of lateral habenular complex(LHb).0.5 h after the six rats being injected intraperitoneally with Ado,the c-fos protein expression in lateral habenular nucleus was significantly increased compared to the group with saline injection.Conclusion:Ado may restrain the unit discharging electricities of neurons in medial habenular complex but excite those in lateral habenular complex.At the meantime,Ado may increase the c-fos expression in LHb.This provides the experimental evidence that Ado may improve the sleep quality.

Objective To evaluate the efficacy of Chinese botulinum toxin A(CBTX-A)injection in the treatment of motor tics in patients with tic disorder.Methods Twenty-five patients(20 male,5 female)were treated with CBTX-A in the sites of their most problematic motor tics.Before treatment the data of Yale Global Tic Severityb Scale(YGTSS)was collected.All patients were assessed at least 3 times after 1 week,4 weeks and within 12-month period.At each visit the following data were collected:YGTSS,Jankovic clinical rating scale,time to response,duration of response,global impression of changes by patients,presence of premonitory sensory tic component and side effects.Results Total number of treatment sessions was 29.The mean response time was 5.0 days.The mean duration of response was 4.6 months.The mean peak effect response in Jankovic clinical rating scale was 3.4.Based on YGTSS,62.1% (18/29)was rated as marked improvement,34.5%(10/29)as moderate improvement and only 3.4% (1/29)as no effect.85.7%(18/21)patients had less premonitory sensation symptoms(mean benefit 72.4%(20%-100%)).Weakness in the site of injection and rash were the main side effect. Conclusion CBTX-A is an effective and safe treatment for motor tics associated with tic disorder.

Objective To study the relation between p38 MAPK pathway and multidrug resistance of stomach cancer. Methods The activity of p38 MAPK in gastric cancer cell SGC7901 and multidrug resistant cell SGC7901/VCR was examined by immunoprecipitation after treating with vincristine for 0,2,15,30,60 minutes. Results Vincristine could activate the activity of p38 MAPK in gastric cancer cell SGC7901 and multidrug resistant cell SGC7901/VCR. The difference between them was that in cell SGC7901 vincristine activate the p38 MAPK rapidly whereas in cell SGC7901/VCR slowly. Conclusion Vincristine could affect the activity of p38 MAPK in gastric cancer cell SGC7901 and multidrug resistant cell SGC7901/VCR.

Objective To summarize the experiences on clinical application of flexible cystoscopy,and evaluate the significance of applying flexible cystoscopy in urologists' daily practice.Methods A total of 379 patients underwent examination with flexible cystoscopy,of them 74 patients were with the aim of therapy or related operation.The operation time was counted and the patients' discomfortableness was recorded according to a visual analog scale(VAS).What's more,a satisfaction questionnaire was made by no doctor presenting to check the patients' response to cystoscopy operation.36 male patients were undergone both rigid and flexible cystoscopy operation.The statistical significance of the differences was analyzed after reading the VAS scores and the results of questionnaires were evaluated.Results 223 patients were found to have relative diseases by the examination of flexible cystoscopy.The mean operation time in using flexible cystoscopy was 7.8?0.27 minutes.The median pain scores of male and female patients were 2.9 and 1.3,respectively.The maximum pain was felt by male patients when the cystoscopy went through the membran of urethra.Satisfactory rate in male patients was 99%,and it was 100% when evaluating the questionnaires answered by female patients.For the 36 male patients undergone both rigid and flexible cystoscopy operation,the median pain score was 2.1(0.5-4.5) for flexible cystoscopy,and was 5.7(1.0-10.0) for rigid cystoscopy.After flexible cystoscopy examination,all the 36 patients were satisfied by the operation.However,only 61.1%(22/36) patients were satisfied by the rigid cystoscopy operation.Statistical analysis showed significant difference(P

Objective To investigate the effect of antiserum against VEGF on angiogenesis and growth of bladder cancer in a mouse model in order to explore a novel strategy for the treatment of bladder cancer. Methods Antiserum against VEGF was prepared by using recombinant human VEGF and was identified for its specific affinity with VEGF by ELISA.The bladder carcinoma cell lines BST739 were implanted in T739 mice which were randomly divided into 2 groups:the control group receiving normal mice serum intraperitoneally,and the experimental group receiving antiserum against VEGF intraperitoneally.All the animals were sacrificed at last.Then all the bladder carcinomas were weighted and the microvessel density (MVD) in them was studied by immunohistochemical staining. Results The antiserum against VEGF was prepared and demonstrated with high specificity. The MVD in the antiserum group was lower than that in the control group. But the average weight of tumors was not significantly less in the antiserum group. Conclusions The study shows that to inhibit the activity of VEGF may reduce the angiogenesis in bladder cancer and supports the antiangiogenic therapy for bladder cancer.Inhibition of VEGF activity might become an important way of adjuvant therapy for bladder cancer.
