1.Clinical analysis of 15 patients with thrombotic microangiopathy induced by malignant hypertension
Chinese Journal of Interventional Cardiology 2017;25(2):102-106
Objective To explore clinical characteristics and treatment of the thrombotic microangiopathy (TMA) induced by malignant hypertension, and provide a better understanding of the disease. Methods The clinical manifestations, laboratory examinations, therapeutic methods and prognosis of 15 TMA patients induced by malignant hypertension were analyzed retrospectively. Results The clinical manifestations were characterized by microangiopathic hemolytic anemia, thrombocytopenia and kidney injury. None of the patients required plasma exchange therapy. After antihypertensive treatment, all of 15 patients were discharged with improved clinical condition, remoglobin levels and platelet count. Conclusions The TMA induced by malignant hypertension is different from the classic TMA. Improving the understanding of TMA induced by malignant hypertension will contribute to early diagnosis and targeted treatment.

International Eye Science 2006;6(5):984-987
AIM: To study the antiproliferation of vitamin E succinate (VES) on pterygium fibroblasts in vitro and to find a potential agent for prevention and treatment of primary and recurrence pterygium.METHODS: Primary culture and subculture of pterygium fibroblasts were established in vitro ,and different concentrations of VES (0, 10 and 20mg/L) were added to subcultured fibroblasts, respectively. Influence of VES on the growth curve of fibroblast was observed at day 2, 4 and 7 after treatment of VES. 3- [4,5-Dimethylthiazolzyl]-2,5-Diphenyl Tetrazolium Bromide (MTT) assay at 490nm was used to evaluate the effect of the cells proliferation.RESULTS: The addition of VES to culture caused the marked descent of growth curve in comparison with the control group, and the inhibiting rate of 10 and 20mg/L of VES was 33.2% and 46.7%, 67.9%, and 76.8%, 81.7% at day 2,4 and 7, respectively. VES could obviously inhibit the fibroblast proliferation in dose-dependent manner by MTT assay.CONCLUSION: VES can significantly inhibit the proliferation of pterygium fibroblast in vitro.

OBJECTIVE:To evaluate the bioequivalence of the domestic pidotimod granules with the imported pidotimod syrup as control.METHODS:20 healthy male volunteers were treated with a single dose(800 mg)of pidotimod granules(test formulation)or pidotimod syrup(reference formulation)by a randomized crossover design,with plasma concentrations of pidotimod determined by HPLC and pharmacokinetic parameters of pidotimod computed,and the bioequivalence between two formulations was evaluated using DAS2.0 program.RESULTS:The pharmacokinetic parameters of the reference formation vs.the test formulation of pidotimod were expressed as follows:t1/2(2.70?0.80)h vs.(2.62?0.84)h;Cmax(4.04?0.59)?g?mL-1 vs.(3.87 ?0.66)?g?mL-1;tmax(2.28?0.44)h vs.(2.13 ?0.43)h;AUC0~14(22.11?4.20)mg?h?L-1 vs.(23.00?4.25)mg?h?L-1;AUC0~∞(22.85?4.42)mg?h?L-1 vs.(23.83?4.52)mg?h?L-1.The relative bioequivalence of the test formulation as against the control was(106.08?22.05)%.CONCLUSION:The pidotimod granules and pidotimod syrup are bioequivalent.

ObjectiveTo investigate the mechanism by which tetracycline inhibits the development of experimental abdominal aortic aneurysms (AAA).MethodsMale Wistar rats underwent intraluminal perfusion of the abdominal aorta with 50 units of porcine pancreatic elastase followed by treatment for 14 days with tetracycline (25?mg/day, subcutaneously; n=10) or with NS alone (n=10). Aortic wall elastin and collagen concentrations were measured with image analysis system and fixed aortic tissues were examined by light microscopy for inflammation. The expression of MMP-2 and MMP-9 were observed in aortic tissues using immunohistochemistry and molecular in situ histohybridization technique. Results AAAs developed in all NS-treated rats, and only 1/10 of tetracycline-treated rats at 14 days(P

BACKGROUND:At present, there is no relevant systematic research about the effects of ankle-foot orthoses on lower limb muscles. OBJECTIVE:To extract the main features of the surface electromyography signals of the lower limbs from normal people with ankle-foot orthoses and to analyze the effects of the fixed ankle-foot orthoses on lower limb muscle fatigue. METHODS:Each of five male healthy young adults was respectively required to walk with and without special ankle-foot orthoses for three times. (1) Group 1, walking in a nature gait without orthoses. (2) Group 2, walking in a natural gait with ankle-foot orthoses (the ankle center was packaged over 1.0 cm by the orthoses that was recorded 1.0 cm); wearing the same orthoses but 1.0 cm in the ankle was removed and the ankle plastic edge was just through the ankle center to colect the data (recorded as 0 cm); after 1.0 cm was removed again in the ankle, walking in a natural gait (recorded as-1.0 cm). (3) Group 3, wearing 1.5 cm heel-height ankle-foot orthoses and walking in a natural gait; wearing the same orthoses but with 1.0 cm and 2.0 cm heel-height and walking in a natural gait. During walking, surface electromyography signals were colected from the biceps femoris muscle, rectus femoris muscle, tibialis anterior muscle, and gastrocnemius of the lower limbs. RESULTS AND CONCLUSION: (1) Without orthoses, the surface electromyography signals were the weakest. (2) For any muscle, the electrical activity of subjects without orthoses was weaker than that of subjects wearing orthoses at different hardness. (3) For the biceps femoris muscle, the integral electrical value without orthoses was very close to that wearing orthoses with normal heel height. Meanwhile, these two values were lower than that wearing orthoses with abnormal heel height. These findings indicate that the fixed plastic ankle-foot orthoses could cause the fatigue of the biceps femoris muscle, rectus femoris muscle, tibialis anterior muscle, and gastrocnemius; and the orthoses with abnormal heel height can further increase the fatigue of the biceps femoris muscle.

The medical education has long paid great attention to students' specialized knowledge education and neglected the humanities education for all-around development excessively. Diagnostics is a bridge curriculum between basic medicine and clinical medicine. Enhancing the quality education by fully combining the process of diagnostics teaching plays an important role in qualified medical talents training.
