Objective To investigate serum leptin levels in maintenance hemodialysis (MHD) patients with chronic renal failure and the relationship between serum leptin levels and nutriture.Methods After hemodialysis,the brachial triceps skin fold was determined in MHD patients,then counted the body mass index(BMI) Serum leptin levels of 55 MHD patients and 40 normal controls were measured by radioimmunossay (RIA) .Simultaneously, other biochemical parameters;BUN, creatinine, serum albumin, triglyceride, cholesterol ,HLD,LDL etc also were mensured.Results ⑴Serum leptin levels in MHD patients were significantly higher than that in normal controls(P

Objective The goal of the present experimental study is to investigate effects on the injection of a-dult rabbit autologous skeletal myoblasts into the thyroarytenoid(TA)muscle after recurrent laryngeal nerve (RLN) damage and traumatic vocal cords .Methods 20 adult New Zealand white rabbits were used for the establishment of an animal model simulating the cut -off of the left recurrent laryngeal nerve and the left vocal cord trauma scar for-mation after traumatic damage .Then from the rabbits ,the sternocleidomastoid muscle cells were cultured ,separa-ted and expanded .After 12 weeks ,the 20 animals were randomly divided into group A ,group B with 10 in each group .Group A(myoblast injection group) in the left vocal cord thyroarytenoid muscle injection of myoblasts 0 .3 ml ,the right vocal cord without any treatment served as normal controls ;Group B(saline injection control group) in the left vocal cord thyroarytenoid muscle was injected with normal saline ,the right vocal cord without any treatment as normal controls ,respectively ,were observed after 12 weeks of bilateral thyroarytenoid muscle fiber diameters and vocal cord volumes .Results After 12 weeks ,Group A's left thyroarytenoid muscle injection of bilateral thyroaryten-oid muscle fiber diameter and the vocal volume size was not significantly different (P>0 .05) ,thyroarytenoid muscle fiber diameter and the vocal cord volume on Group B's injected side was significantly smaller than Group A (P<0 .05) .Conclusion The thyroarytenoid muscle injection of autologous myoblasts can effectively treat recurrent la-ryngeal nerve (RLN) injury and traumatic vocal cords .

Objective:To evaluate the short-term economic effects of four kinds of premixed insulin in newly diagnosed type 2 dia-betes mellitus. Methods:A total of 120 newly diagnosed patients with type 2 diabetes mellitus were divided into four groups according to the kind of premixed insulin, group A was treated with insulin aspart 30 injection, group B was treated with insulin lispro 25 injec-tion, group C was treated with isophane protamine biosynthetic human insulin injection and group D was treated with protamine zinc re-combinant human insulin injection. The course of treatment was three months. The therapy efficacy was assessed by the remission rate in three months. The short-term economic effect was evaluated by the cost-minimization analysis method. Results:The remission rate of group A, B, C and D respectively was 48. 39%, 48. 28%, 51. 61% and 51. 72% without significant difference (P>0. 05). The average cost per person of the four groups was 1195. 52, 1202. 41, 1220. 69 and 1258. 84 yuan, and the average medicine cost per person was 750. 52, 689. 41, 754. 69 and 764. 34 yuan, respectively. There was no significant difference in cost among the four groups (P >0. 05). Conclusion:All the four kinds of premixed insulin can be used for the starting treatment with the similar total cost, and in relative terms, aspart 30 injection and insulin lispro 25 injection are better for the initial treatment of diabetes.

Since the fecal bacteria transplantation (FMT) had been exist for a long time, it attracted more attention in recent years because this therapy could adjust the bacteria disturbance rapidly in clinical settings. Recent studies demonstrated that fecal microbiota transplantation (FMT) has great clinical value in the treatment of Clostridium difficile infection, inflammatory bowel disease, Intractable functional constipation and other diseases. But the FMT is not as perfect as we expect, so we did this article to review the history and terminology of FMT, and summarized the progress in nursing methods of FMT.

Objective The CT features of hepatic abscess (HA) were studied to differentiate form hepatocellular carcinoma(HCC).Methods The CT and operative-pathological findings of 78 cases with HA were analyied and compared with the CT appearances of a series proven cases of HCC.Results None of 25 cases had the so-called typical findings such as the marginal"double-target sign"and the even liquidizing necrotic area and containing gas zone within the lesion,53 cases had the central even liquidizing necrotic area,the marginal "Double-target sign",and containing gas zone within the lesion.Most of a typical hepatic abscess were early HA,and the precontrast CT showed nonspecific features.There were characteristic features on contrast CT.They were peripheral multicyst sign,sharp-edged sign spider-like sign,continued enhancement sign.Conclusion The CT features of HA are very valuable for the diagnosis of HA and the differential diagnosis from HCC.

AIM: To study the prognositic value of PTEN and Her-2 expression in primary breast cancer.METHODS: 81 breast cancer specimens with 15 years follow-up were obtained from 1989 to 2004.Immunohistochemical methods were used to detect the expression of PTEN and Her-2 in 81 paraffin-embedded specimens.The correlation between expression of PTEN and clinipathological factors was discussed with the Chi-square test.The survival rate analysis results were calculated with Kaplan-meier method.Long-rank test and Cox model by SPSS 10.0 software.RESULTS:(1) PTEN expression significantly affects 5-year and 10-year survival rate of breast cancer(P

With the increasingly strengthening of economic globalization and higher education internationalization,medical imageology as an important intersecting science in life sciences has more and more international communion and cooperation.In China many hospitals and medical colleges require large quantities of medical imageology professionals,and it is very necessary and important to develop the bilingual education in medical imageology,though a series of problems appear in the process.

The developing situation of "big image" makes the medical imaging become an increasingly huge and complicated system.It offers higher request to the medical imaging teaching.The internship of last term is always influenced by attending the graduate student's entrance examination and looking for job,the effect of teaching can't be assured,and it especially important to do well in field trip,thus it can reduce or avoid the phenomenon of "practice after graduate".

With development of medical imaging,especial the wide application of CT,MRI and so on,traditional education method can not meet the needs of the intern-clinical students.Fairly satisfying teaching effects has been achieved for the effective combination of traditional teaching methods with net-work educational method.

Objective To evaluate the short-term and mid-to-long-term clinical effectiveness of endovascular isolation technique with covered-stent in treating Stanford type B aortic dissection. Methods A total of 183 patients with Stanford type B aortic dissection, who were admitted to authors’ hospital during the period from January 2005 to December 2013 to receive endovascular isolation treatment with covered-stent under general anaethesia, were enrolled in this study. The clinical data, including post-operative symptoms, complications, retention time in ICU, hospitalization days, 30-day mortality, etc. were retrospectively analyzed. After discharged from hospital, the patients were followed up to check the situation, position and shape of the stent, the diameter of dissection false lumen, the internal leakage, etc. The survival rate and the quality of life were determined. Results Endovascular isolation procedure with covered-stent was successfully accomplished in all the 183 cases. The retention time in ICU was (3.08 ± 1.93) days, the mean hospitalization time was (3.08 ± 1.93) days, and the 30-day mortality was 1.09%. After discharged from hospital, the patients were followed up regularly, and no collapse or displacement of stent was observed, and the stent remained in its normal shape. No recurrence of dissection, rupture or reversal tear was observed. No long existing internal leakage could be detected. During the follow-up period 4 patients died, among them three died from cerebral infarction and one died of natural death. The 5-year survival rate was 97.82% and the patient’s quality of life did not become apparently worse. Conclusion For the treatment of Stanford type B aortic dissection, endovascular isolation therapy with covered-stent has excellent short-term effect and stable mid-to-long-term result.
