Objective To study the relation of different TCM syndrome types of hypertension combined with metabolic syndrome (MS) patients with retinal vascular changes and the urinary microalbumin, and provide objective basis for TCM treatment with syndrome differentiation. Methods Seventy-six patients of hypertension combined with MS (divided into four syndrome types) and 20 patients with simple hypertension were selected. General data, biochemical indexes, retinal vascular changes and the urinary microalbumin were detected and compared. Results In patients with hypertension combined with MS, blood lipid disorders and high blood sugar was mainly focused on the type of phlegm and blood stasis mutual and the type of qi and yin deficiency. The incidence of eye and kidney damage in hypertension with MS patients was higher than the simple hypertension patients. The positive rates of retinal blood vessels and renal damage in qi and yin deficiency type and phlegm and blood stasis mutual type were higher than that in other syndrome types. Conclusion Hypertension with MS patients should pay attention to the prevention and control of retinal vascular and renal vascular complications. Fundus examination and detection of early renal damage index can be used as the basis of TCM syndrome differentiation of hypertension with MS.

BACKGROUND:Restoration of tendon integrity and tenacity, and maintenance of ankle joint flexibility, play a crucial role on the rupture of Achiles tendon. OBJECTIVE: To evaluate the muscular force using isokinetic muscle strength test after the ruptured Achiles tendon is repaired, and to assess the repairing effect. METHODS: Muscle power including peak torque, peak torque/body weight, total work, average peak torque, set total work of flexor and extensor of 17 patients with Achiles tendon rupture were assessed after reconstruction using Biodex system 4 at 60 (°)/s and 120(°)/s. RESULTS AND CONCLUSION:The peak torque, peak torque/body weight, total work, average peak torque, set total work of flexor muscle group at the injured side were significantly decreased compared with uninjured side at 60 (°)/s and 120 (°)/s (P < 0.05). Isokinetic muscle strength test can reflect the muscular force after the ruptured Achiles tendon is repaired, and evaluate the repairing effect.

Objective To investigate the difference among neonatal rat models of hypoxia-ischemia induced white matter injury of brain by three different methods and to provide theory basis on choosing the proper animal model for deep study on white matter injury of premature infants.Methods Three different hypoxia-ischemia methods were applied to induce brain white matter injury model of Wistar rats of postnatal 3rd day which were left carotid artery ligation followed by 6％ oxygen for 30 minutes and for 4 hours respectively,and bilateral carotid artery ligation followed by 8％ oxygen for 30 minutes.Compared brain pathological results of rats in different groups,changes in white matter of brain by glial fibrillary acidic protein (GFAP) and myelin basic protein (MBP) immunostaining,and changes in time of opening eyes and eyes appearance.Results Left carotid artery ligation followed by 6％ oxygen for 30 minutes resulted in sparse and vague periventricular white matter without necrotic lesions,and the degree of GFAP intensity [(5 021.63 ± 358.92) OD] increase and MBP intensity [(18 488.63 ± 1 822.62) OD] decrease were lowest (P ＜ 0.000 1),as well as the delay of opening time of the left eye.Left carotid artery ligation followed by 6％ oxygen for 4 hours resulted in necrotic lesions of periventricular white matter,with the degree of GFAP intensity [(6 069.13 ± 458.61) OD] and MBP intensity [(15 003.38 ± 1 559.11) OD],and also the delay of opening time of the left eye.Bilateral carotid artery ligation followed by 8％ oxygen for 30 minutes caused cystic necrosis of bilateral periventricular white matters,and the degree of GFAP intensity [(6 194.50 ±432.69) OD] increase and MBP intensity [(10 119.35 ± 735.16) OD] decrease of the left side were highest(P ＜ 0.000 1),as well as the delay of opening time and cataract in both eyes.Conclusion Left carotid artery ligation followed by 6％ oxygen for 30 minutes is more suitable for investigating mild brain white matter injury.Left carotid artery ligation followed by 6％ oxygen for 4 hours and bilateral carotid artery ligation followed by 8％ oxygen for 30 minutes are more proper for the investigation of severe periventricular leukemacia cases.

Objective We want to study the therapeutic efficiency of autologous ADMSC transplantation in myocardial infarction.And we try to find out a good way to improve the therapeutic efficiency by using the combination of gene therapy and cell therapy.Anti-apoptotic protein XIAP was selected to fight against the ischemic environment of myocardic infaction.Methods ADMSC was isolated from rat inguinal fat tissue.ADMSC was cultivated with DMEM.XIAP experession plasmid was elertco-transduced to ADMSC.The anti-apototic function of XIAP was tested by serum stavation induced apotosis.The method of ligation of the left anterior descending artery was used to prepare the Myocardial infarction model.Then rats were randomly separated into three groups to receive direct epicardial injections of normal saline,or ADMSCs cell suspension or XIAP modified ADMSCs cell suspension at five sites in central zones of myocardial infarction and border zone.Cardiac function and the infarct size were evaluated 4 weeks after ADMSCs transplantation.Results West blotting suggest that,XIAP over-expression block serum starvation induced apotosis.It showed that there are significant statistic difference among XIAP modified ADMSC transplantation group,ADMSC transplantation group and control group 4 weeks after myocardial infarction (P ＜ 0.05).Left ventricular ejection fraction(LVEF) showed a significant improvement in ADMSCs transplantation group compared to control group (P ＜0.05).Left ventricular end systolic diameter(LVDs) and left ventricular end diastolic diameter(LVDd) of ADMSCs group were smaller than control group(P ＜ 0.05).The area of myocardial infarction was significantly reduced in the ADMSCs transplantation group compared to the saline group(P ＜0.05).Compared to ADMSCs transplantation group,effect of the XIAP modified ADMSC in rats with myocardial infarction is more obvious.The reduction of LVEF of XIAP modified ADMSCs group was signific antly lower(9％) than the ADMSCs group(16％) (P ＜ 0.01).Infarction area in XIAP modified ADMSCs group(3.26 ±0.95)％ was smaller than ADMSCs group(5.17 ±2.03)％ (P ＜0.05).Conclusion Autologus ADMSC transplantation is an efficient therapeutic tool in myocardial infarction therapy.Over expression of XIAP can partly inhibit lowserum induced apotosis of ADMSC in vitro,and it can improve left ventricular function better in vivo.Over expression XIAP of ADMSC can improve the therapeutic efficiency compare to ADMSC transplantation.
