Objective To investigate the effects of different body temperatures on the neuromuscular block induced by different doses of cisatracurium in rabbits. Methods Seventy-two healthy New Zealand white rabbits of both sexes weighing 2.0-2.2 kg were randomly divided into 3 groups (n=24 each): hypothermia group (L), normothermia group (N) and hyperthermia group (H). The rectal temperature was set at 34.5℃, 38.5℃ and 41.8℃ in group L, N and H respectively. Each group was further divided into 4 subgroups (n=6 each) receiving intravenous cisatracurinm 0.33, 0.66, 0.99 and 1.32 mg/kg respectively after rectal temperature was stabilized for 20 min. The animals were anesthetized with iv 20% methane 1 g/kg, tracheostomized and mechanically ventilated (VT 12 ml/kg, RR 60 bpm, I:E = 1:2;FiO2 100% ). TOF was monitored. The onset time, the duration of action (from the end of cisatracurium injection to the recovery of T1 to 5%, 25% and 95% of control height) and recovery index (recovery of T1 from 25% to 75% of control height) were recorded. MAP, HR and rectal temperature were recorded at 5 min before alteration of the body temperature, at 2 min before and 5, 10, 30, 60 and 90 min after administration of cisatracurium. Results (1) With the same dose of cisatracurium the onset time and duration of action were significantly shorter in group H, longer in group L and recovery from N-M block faster in group H, slower in group L as compared with group N. (2) At the same body temperature the onset time was significantly shortened and the duration of action and recovery were significantly prolonged as the dose of cisatracurium increased. (3) There was significant difference in the effect of interaction between different doses of cisatracurium and different temperatures on the onset time. (4) With the same dose of cisatracurium MAP was significantly decreased in group H, increased in group L, while HR was significantly increased in group H, decreased in group L. Conclusion The neuromuscular blocking effect of cisatracurium is decreased when the body temperature is increased and vice versa. The neuromuscular blocking effect of cisatracurium (0.33-1.32 mg/kg) is dose-dependent at the same body temperature. There is interaction between the two factors.

Objective To explore the relationship between the levels of plasminogen activator inhibitor-1(PAI-1) and type 2 diabetes mellitus (T2DM) with vascular complication. Methods The plasma concentrations of PAI-1 were determined by ELISA in 34 control subjects (Control group) and 134 diabetic patients (T2DM group),which were further subdivided into 4 subgroups based on body mass index (BMI) and with or without macro-vascular complication. Results The PAI-1 levels in four diabetic subgroups were significantly increased compared with those of the control. The PAI-1 level in T2DM with macroangiopathy was significantly higher than that in T2DM patients without macroangiopathy (P

BACKGROUND:Human skin-derived precursors can be cultured for a long term in vitro, and differentiated into neurons, glial cel s, smooth muscle cel s, Schwann cel s and cel s with peripheral neurons phenotype.
OBJECTIVE:To investigate the culture conditions and multiple differentiation capacity of multipotential stem cel s from human skin, especial y the potentials of differentiating into neurons and osteoblasts.
METHODS:Human skin-derived precursor cel s were cultured with trypsin digestion method, and identified with immunocytochemistry. Cel s at passages 3-4 were induced to differentiate into neurons and osteoblasts, and underwent von Kossa staining protocol for calcium, chondrocyte induction, toluidine blue staining, immunohistochemical staining and Sudan black staining. The expression of nestin, vimentin,βIII-tubulin, S100 and col agen II in the human skin-derived precursors was detected.
RESULTS AND CONCLUSION:The human skin-derived precursor cel s cultured with trypsin digestion method could proliferate and form suspending spheres, and nestin positive cel s were detected at any time point of the culture. Al the cultured cel s expressed vimentin, and some adherent cel s expressedβIII-tubulin. Human skin-derived precursor cel s were induced with Salvia miltiorrhiza to differentiate into neuron-like cel s, and expressed marker of nerve cel s. Skin-derived precursors could be induced to differentiate into osteoblasts and von Kossa staining displayed black calcified nodules in the culture dish. Skin-derived precursors could also be induced to differentiate into chondrocytes, and toluidine blue staining was strongly positive, and some cel s expressed col agen II, which suggested that, the differentiated cel s contained chondrocytes. Experimental findings indicate that, skin contains multipotential stem cel s that are capable of differentiating into osteoblasts, chondrocytes, Schwann cel s and oligodendrocytes.

Objective:To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods:Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.0.
Results:The ratio of male to female inpatient numbers was 3.13:1, aged was between 40 and 70 years. The most common subtype of psoriasis was psoriasis vulgaris (64.73%), followed by psoriatic erythroderma (18.42%). The distribution of the subtype of psoriasis did not differ by gender. Nineteen patients recalled clearly the cause of proriasis, 5 of which were caused by medicine, and 4 by drinking. Totally 96 cases accompanied with other diseases, 24.21%of which accompanied with cardiovascular system disease.
Conclusion:There is no season difference in the hospitalization of patients with psoriasis. there are more male than female inpatients. Treatment of psoriasis should consider clinical classification, drug adverse reactions, and individual factors for individual treatment.

BACKGROUND:There are myoblasts in human embryonic skeletal muscle. It remains poorly understand whether myoblasts in vitro can form myotube and what are the corresponding markers for identifying myoblasts and myotubes. OBJECTIVE:To investigate whether in vitro cultured myoblasts from human embryonic skeletal muscle can form myotube and whether they can express neural markers. METHODS:Human embryonic muscle-derived myoblasts were cultured in serum-containing medium. When the primary culture was established, cultured cel s were identified with immunocytochemistry for neural markers, such asβ-tubulin markers (desmin, myogenin, smooth muscle actin and myosin). RESULTS AND CONCLUSION:A population of myoblasts could migrate from human embryonic muscle tissues. They could express the markers for skeletal muscle such as desmin and myogenin, and they could express neuron specific enolase, nestin and neurofilament 200. They could form myotubes in vitro, and myotubes expressedβⅢ-tubulin, neurofilament 200 and glial fibril ary acidic protein. The data support the hypothesis that myoblasts from human embryonic muscle express neural markers and muscle markers, and cultured myoblasts and myotubes expressed neuron specific enolase,β-tubulin Ⅲ, nestin, neurofilament 200 and glial fibrillary acidic protein. This indicates that these markers could not be used for cel identification of trans-differentiation study from muscle origin to nervous system.
