Basic medical theory integrating with clinical practice is the motivation of medical development.In our country,basic medical theory research levels has been low because of mismatch between clinic practice and basic research in lots of affiliated hospitals of medical colleges.In this paper,according to analysize the basic medical research status of several affiliated hospitals of Shantou University Medical College,we think that it is key for enhancing basic research levels to strengthen building clinical research platform,standardize management of scientific research and guide medical staffs carrying out basic theory research from clinic practice.

Environmental endocrine disrupting chemicals (EDC) may interfere with thyroid function by affecting the synthesis,release,transport,metabolism,and clearance of thyroid hormone as well as its receptor binding,etc.Thyroid hormones are essential for normal fctal brain development and for many aspects of normal adult physiology.This paper is to provide a brief overview of recent findings on thyroid disruptionly EDC.It would contribute to the development of new strategies against thyroid dysfuction.

The dynamic changes about vasoactive intestinal peptide (VIP), angiotension Ⅰ (AⅠ)and angiotension Ⅱ (A Ⅱ)concentrations in plasma, cerebral spinal fluid (CSF) and brain extracts were studied in the experimental high-velocity missile wound models, which were produced on both hind legs of dogs. The findings were as follows: (1) Plasma VIP, AⅠ and AⅡ concentrations started to increase from 30 rain after the wound and the elevation had been continuing at 4 h after the wound. Their highest points of post-trauma were 2,9, 11.5 and 4.9 times as much as that of pre-trauma. (2) CSF VIP elevated at 4 h after the wound, but AⅠ and AⅡ concentrations reduced tempo tarily at 1 h and 2 h after the wound respectively. (3) The changes of VIP, AⅡ concentrations in the brain extracts tented to be consistent with that of the CSF. The signifcance and machanism of these changes of VIP and AⅡ concentration remain to be clarified.

Objective: To study the morphologic and functional changes of the valve after tricuspid valve prosthesis. Methods: Sixty five patiens whose ages averaged (44.6?10.6) years underwent valve replacement and tricuspid value reconstruction. Color Doppler echocardiography were performed before and after operation. Results: Follow up averaged 12 months after operation, the morphology of tricuspid valve was normal. The diameter of the annulus decreased to (2.2?0.2) cm ( P

Objective: To evaluate the surgical results of aortic valve replacement with autologous pericardial valve. Methods: Nine patients underwent aortic valve replacement with autologous pericardial valve were studied by color Dopplor echocardiography (HP 1000 type). The mobility, thickness, opening amplitude, valve orifice areas, regurgitant stroke volume and transorifice pressure gradient of the autologous pericardial valves were measured and analysed intraoperatively and postoperatively. Results: 10 days postoperation, there was no significant difference in above mentioned indices between patients and normal group. Two years after operation, the mobility, thickness, opening amplitude, valve orifice areas, regurgitant stroke volume and transorifice pressure gradient of the autologous pericardial valves showed no significant changes, the EDV and LVEDD significant reduced as compared with 10 days postoperatively. Conclusion: Two years after operation, the structure and function of the autologous pericardial valve may maintain good condition.

Objective To study the clinical features, laboratory index and therapy of hypoplastic myelodysplastic syndrome. Methods 8 patients with hypoplastic MDS by using the method of bone marrow smear and bone marrow biopsy were studied. T lymphocyte subsets were analyzed by flow cytometry. 8 patients were treated with personalized therapy. Results All the patients of this group had hypoplastic bone marrow with more than two parts, bone marrow hypocellularity and characteristics of ineffective hematopoiesis. The analysis of T lymphocyte subsets showed that 5 of 8 patients had abnormal CD+4/CD+8 ratios. After personalized treatment, there were 2 obvious remission cases, 3 partial remission cases, 2 progression cases and 1 inefficacy case. Conclusion Hypoplastic MDS is characterized by bone marrow hypocellularity and ineffective hematopoiesis, which showed immunological abnormalities. Personalized therapeutic strategy may prolong survival in patients with hypoplastic MDS.

Patients with non-alcoholic fatty liver disease (NAFLD) have unhealthy diets, sedentary behavior and lack of physical activity. This lifestyle triggers liver disease and probably favors its progression. It is now the most common significant cause of end-stage liver disease and hepatocellular carcinoma. From the perspective of non-pharmacological intervention, lifestyle modifications including diet, exercise, and weight loss remain the most effective therapy for nonalcoholic fatty liver disease. Bariatric surgery in morbidly obese individuals who have failed to lose weight through lifestyle modifications can improve steatosis, inflammation, and fibrosis. Comprehensive treatment measures can produce synergistic effect, but long-term adherence is particularly critical.
