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.

In 54 cases of pulmonary hypertension, the PaCO2 was markedly lowered, PaO2 and SaO2 elevated, HR, CO and mPAP, PVR all lowered in the treatment group (P0. 05), but SBP was significantly different (P

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.

0.05).It was revealed by ROC curve analysis that P-LAP≤38.12 U/L and IL-6≥3.40 pg/mL could be adopted as criteria to predict the inevitable preterm labor,and the Youden's index of the combination use of the parameters of P-LAP and IL-6 was significantly higher than that of the single use of each parameter(P

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.

AIM:Todetecttheeffectofspironolactoneonhyperthyroxine-inducedatrialremodeling.METH-ODS:New Zealand rabbits were divided into control group ( C ) , hyperthyroxine group ( H ) and spironolactone group ( S) .Thyroxin was given to the rabbits in group H and group S by intraperitoneal injection for 4 weeks , and then spirono-lactone was given in group S by gavage for 2 weeks.Atrial fibrillation (AF) was induced by burststimulation after ad-ministration.The inducing rate of AF and atrial effective refractory period ( AERP) were tested by intra-cardiac electro-physiologic instrument.The expression of AF-related Ca2+channel (Cav1.2), K+channels (Kv1.5 and Kv4.3) and con-nexins (Cx40 and Cx43) at mRNA and protein levels was detected by real-time PCR, immunohistochemistry and Western blot.RESULTS:Spironolactone reduced the inducing rate of AF .No significant difference of AERP between group H and group S was observed (P>0.05).Compared with group H, the protein expression of Cav1.2 was significant increased in group S (P<0.05).The expression of Kv1.5 at mRNA and protein levels in group S was significantly lower than that in group H (P<0.05), while the protein expression of Kv4.3 in group S was significantly decreased compared with group H (P<0.05).The mRNA expression of Cx43 in group S was significantly decreased compared with group H (P<0.01), whereas the protein expression of Cx 40 in group H was significantly higher than that in group S ( P<0.05 ) .CONCLU-SION:Spironolactone attenuates the hyperthyroxine-induced atrial remodeling in rabbits , and reduces the susceptibility of the myocardium to AF .

The article describes the current situation of training mode of community nurses in community health service institutions in Hubei province from several aspects,including training object,training target,training base,teaching staff,training organization and government,training method and time,training curriculum,training effect evaluation and certification.The article suggests a multitude of factors influencing the training quality,such as formal training,dominant job training,and monotonous community training content and less training time.Overall,the government should be done something to increase government support and funding and accelerate the community nursing services and community nursing education.It is also essential to establish community nursing personnel training mechanism,improve and perfect the community health personnel training system,increase the construction of community nursing practice base and facilities and strengthen clinical practice skills.

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.
