ObjectiveTo study the effect of heat stress on the cytoskeleton and cell cycle of human umbilical vein endothelial cell (HUVEC) in vitro.Methods HUVEC was cultured in vitro in 5%CO2 medium at 37℃ (control group) or 43℃ (heat stress group) for 1 hour. Coomassie brilliant blue R-250 staining was used to determine the effect of heat stress on the cytoskeleton. The cells in heat stress group were subsequently cultured at 37℃in 5%CO2 medium after heat stress for 1 hour, and cell cycle of HUVEC was determined at 0, 6, 12, 18 and 24 hours with flow cytometry.Results Under light microscopy normal cytoskeleton was observed in control group, but thicker and shorter cytoskeleton was found after a rise of temperature, and stress fibers were found in heat stress group. The DNA content of HUVEC at all time points in G0/G1 stage was 38.07%-55.19% after heat stress. The DNA content in control group was 48.57%, and it was 54.06%, 55.19%, 48.23%, 38.07%, and 41.03% at 0, 6, 12, 18, 24 hours in G0/G1 stage in heat stress group. DNA content in S phase was 35.33%-48.18%. The DNA content in control group was 44.62%, and it was 35.33%, 39.50%, 42.50%, 48.18%, and 47.99% at 0, 6, 12, 18, 24 hours in S stage in heat stress group. DNA content in G2/M phase was 5.31%-13.75%. The DNA content in control group was 6.81, and it was 10.61%, 5.31%, 9.27%,13.75%, and 10.98% at 0, 6, 12, 18, 24 hours in G2/M stage in heat stress group. It was demonstrated that compared with control group, the DNA content in G0/G1 stage was significantly increased when the HUVEC were separated from heat stress within 6 hours, and it recovered at a similar level as control group at 12 hours.Conclusion Heat stress can change the cytoskeleton of HUVEC, and cause stagnation at G0/G1 stage in cell cycle.

Performing CPAP treatment before operation had a beneficial effect to the avoidance of emergency-event.

Objective To analyze the prognosis of advanced esophageal carcinoma treated with paclitaxel and different platinum?based chemotherapy regimens plus intensity?modulated radiotherapy ( IMRT) , and to explore an optimal chemotherapy regimen. Methods A total of 242 patients with advanced esophageal carcinoma who were admitted to our hospital and treated with paclitaxel and cisplatin ( 68 patients), nedaplatin (85 patients), lobaplatin (58 patients), or oxaliplatin (31 patients) plus IMRT from 2008 to 2014 were enrolled as subjects. The prognosis of the four groups was analyzed after 2, 3, and ≥4 cycles of chemotherapy. The survival rates were calculated by the Kaplan?Meier method and analyzed by the log?rank test. The Cox model was used for the multivariate prognostic analysis. Results The sample number of 3 years was 168 cases. In all the 242 patients, the medium survival time was 31. 1 months and the 3?year overall survival ( OS) rate was 47. 4%. There was no significant difference in the 3?year OS rate between the cispaltin, nedaplatin, lobaplatin, and oxaliplatin groups ( 46. 2% vs. 56. 4% vs. 45. 7% vs. 29. 0%, P=0. 090) . The stratified analysis showed that the cisplatin, nedaplatin, and lobaplatin groups had a significantly higher OS rate than the oxaliplatin group ( 50. 1% vs. 29. 0%, P=0. 021 ) . There was no significant difference in the 3?year OS rate between patients receiving 2, 3, and≥4 cycles of chemotherapy ( 40. 1% vs. 49. 5% vs. 50. 8%, P=0. 264) . The multivariate analysis showed that esophageal tumor volume and the maximal size of metastatic lymph node were independent prognostic factors. Conclusions Combined with IMRT, paclitaxel plus cisplatin, nedaplatin, or lobaplatin?based chemotherapy achieves improved survival rates than paclitaxel plus oxaliplatin?based chemotherapy. Esophageal tumor volume and the maximal size of metastatic lymph node are independent prognostic factors.

ObjectiveTo observe the effect of Xuebijing injection pretreatment on systemic inflammatory response induced by severe heat-stroke, and to investigate the mechanism of alleviation of intestinal injury in rats. Methods Thirty-six healthy adult male Wistar rats with grade SPF were randomly assigned into three groups with randomized number method, namely sham group, severe heat-stroke model group, and Xuebijing pretreatment group (XBJ group), with 12 rats in each group. The animals were placed in a pre-warm chamber [temperature (40±2)℃, humidity (65±5)%] in order to induce typical heat-stroke. The duration of heat-stress was 60 minutes, while the animals in sham group were exposed to ambient temperature of 25℃. Arterial blood samples were collected at the beginning and the end of heat-stress, the concentrations of tumor necrosis factor-α(TNF-α), interleukins (IL-1β, IL-6), and lipopolysaccharide (LPS) in peripheral blood were determined by enzyme linked immunosorbent assay (ELISA). The intestinal tissues were harvested after heat-stress, and the pathological changes in intestine tissues were observed after hematoxylin-eosin (HE) staining and under optical microscope. The pathological injury scores were calculated. Immunohistochemistry was performed to determine inducible nitric oxide synthase (iNOS) expression in intestinal tissue. Apoptosis was determined by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) staining. Western Blot was used to measure the tight junction protein occludin expression.Results The concentrations of TNF-α, IL-1β, IL-6 and LPS in blood of the rats after heat-stress in model group were significantly higher than those of sham group [TNF-α (μg/L): 443.00±110.10 vs. 98.36±44.61, IL-1β (μg/L): 436.37±163.64 vs. 64.24±16.15, IL-6 (μg/L): 342.70±92.42 vs. 54.40±13.22, LPS (μg/L): 0.68±0.22 vs. 0.09±0.02, allP< 0.01], but the levels of these parameters in XBJ group were significantly lower than those of model group [TNF-α (μg/L):340.45±68.57 vs. 443.00±110.10, IL-1β (μg/L): 191.33±82.78 vs. 436.37±163.64, IL-6 (μg/L): 192.21±37.89 vs. 342.70±92.42, LPS (μg/L): 0.43±0.17 vs. 0.68±0.22, allP< 0.01]. Infiltration of inflammatory cells, necrosis and hemorrhage in intestinal mucosa were found in the intestine of heat-stroke animals in model group. The pathological lesions in XBJ group were milder than those of model group, with a decreased pathological injury score compared with model group (2.10±1.15 vs. 3.20±0.67,P< 0.01). The expression of iNOS and apoptosis of cells in intestinal tissue in model group were increased compared with that of sham group, but they were significantly less marked in XBJ group compared with model group [iNOS (adjustedA value): 0.32±0.15 vs. 0.74±0.17, apoptotic index: 0.23±0.08 vs. 0.56±0.07, bothP< 0.01]. The order of expression for occludin protein from high to low was sham group, XBJ group and model group (A value was 0.96±0.25, 0.62±0.20, 0.33±0.11, respectively). Furthermore, there was significant difference in the expression of occludin protein between model group and both XBJ group and sham group (bothP<0.01).Conclusions Xuebijing injection alleviates inflammation and endotoxemia produced by severe heat-stroke in rats. The mechanism may be related to amelioration of oxidative injury, apoptosis, and dysfunction of tight junction protein occludin expression.

Objective To study the biomechanical mechanism of Essex-Lopresti injury, and provide biomechanical basis for diagnosis and treatment of Essex-Lopresti injury. Methods Twelve fresh frozen adult upper limbs were addressed. Firstly, 12 samples ("complete state group") were loaded 100 N of a compressive force lasting 30 seconds in pronation, supination and neutral position on the mechanical testing machine. Secondly, 12 specimens were randomly divided into 2 groups. In the group named resection of radial head, the radial head was removed and interosseous membrane (IOM)was intact. In the group named the section of interosseous membrane, IOM was cut off. Finally, the radial head were removed and IOM was cut off in all specimens. The group was named as resection of radial head and IOM. Each sample was tested according to the method as described. Results The forearm rotation or single excision of the IOM had no effect on radial longitudinal displacement. Simple radial head excision or resection of the IOM and the radial head increased the vertical displacement of the radius. The radial stiffness had a gradual decline in forearm supination, neutral position and pronation. Simple excision IOM has no effect on the radial stiffness. The radial stiffness had decreased under the condition of excision of radial head or resection of the IOM and the radial head. Conclusion These in vitro measurements validate that the radial head fracture with IOM injury may be important reason for complications of the Essex-Lopresti injury. Radial head fracture play a key role for Essex-Lopresti injury and the injury of IOM is secondary cause. IOM is responsible for maintaining the vertical stability of the forearm after radial head resection.
