The initial study of the tumour DNA fingerprints using MYO minisatellite DNA probe wascarried out,and then,by means of DNA recombinant techniques,the fragment of MYO min-isatellite DNA probe obtained from plasmid pUC19-MYO was inserted into plasmid pGEM-4Z containing RNA polymerase promotor,thus a sub-clone refferred as pGEM-4Z-MYOwas constucted.That made an offer of the conditions of preparing RNA probe in order to in-cerase the sensitivities of DNA fingerprinting and laid a foundation for raised the efficiency of de-tecting the polymorphism of the minisatellite DNA.

A description of the implementation strategy and methodology of clinical medicine as a discipline in terms of building clinical technology features, making scientific research centering on clinical questions, building technical and academic branding, and building discipline bases.Authors also emphasized human resource cultivation, and held that the clinical discipline development should be carried out by means of organization and culture management for the discipline.

Objective:To investigate the non-thymoma thymic morphology in patients with Myasthenia Gravis(MG), and provide the theoretical basis for extended thymectomy.Methods:From September 2008 to March 2018, extended thymectomy had been performed for 150 patients with MG in our department. In order to achieve maximal benefit, combined thoracoscopic and mediastinoscopic approach had been adopted to completely remove both thymus and ectopic thymic tissue in the neck and the anterior mediastinum. Cervical and mediastinal tissue including fat from the thyroid isthmus to the diaphragm was swept away from above the phrenic nerve. The regions containing mediastinal fat were divided into 12 stations.Results:There was no mortality. Pathology reports revealed 126(84.0%) patients with MG had hyperplastic thymus, 17(11.3%)cases with involuted thymus and 7 (4.7%)cases with normal thymus. 98 (65.3%)cases had more than two superior horns, and 59(39.3%) patients had ectopic thymic tissue in the mediastinum and in the neck. Positive rates of ectopic thymic tissue in the 12 cervical-mediastinal fat stations were 7.8%, 10.0%, 8.8%, 3.8%, 3.0%, 2.5%, 0, 0, 0.7%, 13.3%, 12.3% and 9.1%, respectively. After a follow-up period of 2-12 years, the rate of complete stable remission was 44.7%(59/132), and the effective rate was 89.4%(118/132).Conclusion:It is very meaningful to study non-thymoma thymic morphology in patients with MG in order to guide the performance of extended thymectomy and improve its outcome. For the purpose of minimally invasion, one side of mediastinal pleural should be carefully protected.

Objective To explore the effect of suledexide on renal injury and podocalyxin expression of podocytes in STZ diabetic desoxycorticosterone acetate (DOCA)-hypertensive rats. Methods Wistar rats were subjected to subcutaneous injection of streptozotocin(STZ), followed by uninephrectomy and subcutaneous administration of DOCA. Diabetic and hypertensive rats were randomly allocated to treatment with sulodexide or a combination of sulodexide and telmisartan for 8 weeks. Blood pressure (BP), 24-hour urinary albumin were measured every 2 weeks. Blood and urinary samples were collected to detect biochemical indexes of plasma and urinary β-acetyl-β-D-glucosaminidase (NAG) at the end of the study. Immunohistochemistry (IHC), RT-PCR and Western blot were performed to examine the expression and distribution of podocalyxin. Results STZ +DOCA-treated rats progressively developed hypertension, albuminuria and hyperglycemia. Hyperlipidemia and hypoinsulinemia were found in diabetic and hypertensive rats compared with controls. Albuminuia was significantly reduced in sulodexide group at week 8 and sulodexide plus telmisartan group at week 6 and week 8. Blood pressure decreased in sulodexide plus telmisartan group. No significant effects on lipid and glucose metabolism were observed in all treated groups. Histopathological index increased in STZ+DOCA-treated rats, but was significantly lower in sulodexide group as well as sulodexide plus telmisartan group. The number of podocytes on glomerular cross-section of the four groups were comparable. Segmental loss and down-regulation of podocalyxin were detected in STZ+DOCA-treated rats, which were greatly attenuated by sulodexinde, meanwhile, combination treatment preserved more podocalyxin expression in glomeruli than sulodexide monotherapy. Conclusion Sulodexide effectively reduces albuminuria, prevents loss of podocyte podocalyxin and alleviates renal damage in STZ diabetic DOCA-hypertensive rats.

The article reviewed the current status, reform measures and progress of the tiered medical services in Zhejiang province, and analyzed main roadblocks in such a system.Proposals made in the paper include such reform measures as further expanding quality medical resources of better talents and equipments to enhance primary medical institutions;forming the gatekeeper practice featuring firstvisit at community health centers with enhanced primary capabilities;insisting on joint reform of medical treatment, medical insurance and drugs, promoting the development of tiered medical services and utilization efficiency of medical resources in the province.

Objective:To observe the effect of diammonium glycyrrhizinate injection on bronchus,lung tissue and amount of eosinophils(EOS)in rats with asthma and to discuss the mechanism of diammonium glycyrrhizinate intervention on airway inflammation in asthma.Methods:To divide 60 male SD rats into 6 groups as following:normal control group,model group,dexameth group,high dose of diammonium glycyrrhizinate group,middle dose of diammonium glycyrrhizinate group and low dose of diammonium glycyrrhizinate group(n=10).After setting up the model of rats with asthma,we detect the EOS in both rats'blood serum and bronchoalveolar lavage and observe the pathological change in bronchus and lung tissue in rats of each group.Results:Not only the amount of EOS of rats in model group is bigger than that in normal control group(P

One hundred and ten college students, 66 males and 44 females, were studied for the evaluation of vitamin C status by use of the ratio of reduced vitamin C to creatinine in a random urine sample. During the experimental period, the dietary source of creatinine was strictly abstained. After voiding in the morning, the volunteers were weighed and their urine were collected at the end of 1st, 2nd, 4th, 8th, 12th and 24th hr respectively. The contents of reduced vitamin C and creatinine in each collected urine sample were analysed, and then the total amounts in 24 hrs were calculated.The experimental results showed:1. The distribution of the creatinine excretion in 24 hrs was nearly constant.2. The percentage of reduced vitamin C excretion per hour to the total 24 hrs excretion was similar in subjects of different vitamin C status and was lowest in 12 hrs of night urine. A curvilinear regression was given for the percentage of reduced vitamin C excretion in relation to the time.3. The ratio of reduced vitamin C (as mg) to creatinine (as gm) and the ratio of reduced vitamin C to creatinine (as mg) per body weight (as kg) were calculated from their contents in 12 hrs urine in those who exc- reted reduced vitamin C in urine less than 80 mg in 24 hrs. The relationship between these two ratios and the excretions of reduced vitamin C in 24 hrs urine was studied and four equations of curvilinear regressions were given.4. According to these equations, the correlated values of vitamin C/ crcatinine and vitamin C/creatinine/body weight in random urine samples in respect of four different grades of vitamin C excretion of 24 hrs urine were recommended.It was shown to be a new simplified method for evaluating the nutritional status of vitamin C in human body. The practical aspect of its application was discussed.
