Malignant mesothelioma(MM) is a rare but highly invasive carcinoma associated with asbestos exposure.Its incidence is in rising trend and most cases occur in pleura and peritoneum.The majority of patients diagnosed at late stage with poor prognosis that the median overall survival is only 12 months.Accurate diagnosis depends on the histopathology combined with immunohistochemistry.At present, the treatment of MM is mainly based on the tumor reduction or resection surgery combined with chemotherapy and radiotherapy.The potential molecular target needs to be further investigated.In this paper, we summary the incidence, diagnosis and treatment of MM, which will benefit the diagnosis and treatment of MM in China.

Objective To compare the safety of dopamine ( DA) and norepinephrine ( NE) in hypovolemic shock , and the impact on the stability of blood pressure and haemodynamics .Methods Eighty two patients with hypovolemic shock were given fluid resuscitation . All the patients were divided into two groups including DA group (n=41) and NE group(n=41).Recovery of blood pressure, hemody-namic parameters were observed at different time point , and the complications and mortality of two groups were recorded .Results Blood pressure of all the patients returned to normal in 15min after the medication, and became stable after 30min.There was no significant difference in the blood pressure in both groups except that of 15min.Compared with T0, There were higher in the numerous of CVP , CI, ELWI, ITBI.The ELWL at T2 in DA group was higher than that of NE group , while there was no significant difference in the other time points between the two groups(P>0.05).After treatment for 24 h, blood oxygen saturation, urine volume in two groups were significantly increased, blood lactic acid markedly reduced , but lactic acid in NE group was obviously lower than that in DA group (P<0.05).Com-pared with DA group, the incidence of arrhythmia cordis , 2-week mortality in NE group were significantly reduced (P<0.05), while the acute kidney injury in two group was not statistically different (P>0.05).Conclusion The effect of NE and DA in maintaining the stability of blood pressure and hemodynamic are equivalent , and NE did not increase the risk of acute kidney injury , but can effectively improve tissue perfusion , reduce arrhythmia and case fatality rate , improve clinical outcomes .

Objective To explore the establishment methods of animal models of adult growth hormone deficiency, and to provide a good model for experimental research and treatment for abnormal bone metabolism caused by growth hor-mone deficiency.Methods The methods of establishment of animal models of adult growth hormone deficiency were re-viewed and evaluated refering to literature.Results There were three methods including spontaneous lack-of, pituitecto-mized and gene knockout can establish animal models of adult growth hormone deficiency.Conclusions Hypophysecto-mized animal models are inexpensive and easy to create, but not suitable for studying the relationship between growth hor-mone and bone metabolism.Spontaneous lack-of and gene knockout models are specific growth hormone deficiency and of great research significance in exploring the relationship between growth hormone and bone metabolism.

Objective:To investigate the protective effect of Intravenous Injection of Radix Astragali seu Hedysari on acute myocardiac infarction (AMI) in anesthetized dogs. Methods: Twenty health dogs were treated by ligating descending anterior of coronary with two-step method. The changes of electrocardiogram before and after ligation were recorded. After 4 hours myocardium were taken out and dyed with NBT to make sure of the extent of myocardiac infarction.Results: Intravenous Injection of Radix Astragali seu Hedysari could decrease the lethality of AMI, ameliorated ST changes on electrocardiogram induced by AMI, and reduced infarction area. Conclusions: Intravenous Injection of Radix Astragali seu Hedysari is effective in the treatment of AMI in anesthetized dogs.

Background and purpose:The prognostic role of human epidermal growth factor receptor 2 (HER-2) remains controversial in patients with non-small cell lung cancer (NSCLC). This study aimed to evaluate the expression of HER-2 and its prognostic implication in patients with NSCLC.Methods:Four hundred and twenty-ifve NSCLC patients’ specimens were obtained from Zhejiang Cancer Hospital. HER-2 protein expression was determined by immunohistochemistry (IHC). The relationship between HER-2 and clinicopathological parameters and patients’ prognosis was analyzed by Chi-square test and COX proportional hazards regression model.Results:Eighty-three patients were positive expression of HER-2 (83/425, 19.5%). The expression of HER-2 was closely related with histological type (P=0.051), most patients with HER-2 positive were adenocarcinoma, then were squamous carcinoma or other histological types. However, HER-2 was not an independent prognostic indicator for the overall survival of patients with NSCLC.Conclusion:We found that the expression of HER-2 was closely connected with histological type, but it was not a predictive marker for the prognosis in patients with NSCLC.

Objective To investigate the relationship between the serum SRC-3 levels and the bone loss severity in postmenopausal women. Methods Fifty-eight PMW with osteopenia or osteoporosis and nineteen healthy PMW were enrolled in this study from June 2012 to September 2013. BMD at the lumbar spine and femoral neck were observed by DXA Lunar Prodigy Vision. The levels of serum SRC-3 were detected by ELISA. The diagnosis value was evaluated by the ROC curves analysis. Results The levels of serum SRC-3 were significant higher in the normal group than those in the osteopenia or the osteoporosis groups (P<0.001 for both), no statistical significance was found between the osteopenia and the osteoporosis group(P=0.056). The levels of serum SRC-3 were negatively correlated with the BMD diagnosis grading (r=-0.543, P < 0.001). By using the ROC curve analysis, the serum level of SRC-3 for PMW with osteoporosis and osteopenia were found to be 0.297 ng/mL and 0.347 ng/mL, respectively. The levels of serum SRC-3 were positively associated with BMI (r=0.395, P<0.001) and LS-BMD (r=0.503,P<0.001) in the postmenopausal women. Conclusion SRC-3 might be an useful index to reflect the severity of lumbar spine bone loss.

Objective To study whether the effects of bone mineral density by a kidney-tonifying herbal fufang treatment in senile osteoporosis mice (P6) is by the mechanism of improving the expression level of GH mRNA and IGF-1 mRNA. Methods The experimental points four groups as following:SAMR1 mice which feed saline lavage,SAMP6 divid as saline lavage group,subcutaneous injection of rhGH group and a kidney-tonifying herbal fufang treatment group. All intervention is one time everyday. After 3 months and 6 months intervention,we measure the BMD and the expression level of the GH mRNA and of IGF-1 mRNA. Results After 3 months intervention,the BMD of R1 group and the Kidney group were higher than the P6 blank group;but there is no difference in BMD between RhGH group and the P6 blank group. The effect of GH mRNA and IGF-1 mRNA expression levels:the R1 group,rhGH and kidney group were higher than the P6 blank group. After six months intervention,the BMD of the rhGH group and kidney group are higher than the P6 blank group. GH mRNA and IGF-1 mRNA expression levels:GH group and kidney group are higher than the P6 blank group. The expression level of GH mRNA and IGF-1 mRNA in four groups has positive correlation. After six months intervention ,we found the positive correlation between the expression level of GH mRNA and IGF-1 mRNA and each part of the whole body BMD. Conclusion A kidney-tonifying herbal fufang can improve the bone mineral density of P6,and its mechanism may be related to improve expression level of GH mRNA and IGF-1 mRNA.

Risk factors of hyperamylasemia in 152 diabetic ketoacidosis(DKA)patients who had no acute pancreatitis were examined.Serum levels of hemodiastase,natrium,kalium,chlorine,calcium,phosphonium,creatinine,carbon dioxide combining power,osmotic pressure,blood glucose,blood lipids and uric acid were measured.With hemodiastase and other 14 factors as independent variables,the multiple linear regression analysis was performed and the partial regression coefficient was estimated.Blood glucose,serum natrium,osmotic pressure and triglyceride entered the regression equation,and their partial coefficients were 10.26,10.35,2.21 and 8.00,respectively.The constant quantitv was -2162.06.Compared with amylase-normal group,hyperamylasemia group showed statistically significant difference in blood glucose,serum natrium,osmotic pressure and triglyceride levels.Higher blood glucose and triglyceride might be the primary causes of hyperamylasemia.

Objective To further improve level of severe chest trauma care in the elderly pa-tients. Methods A retrospective study was done on data of 148 elderly patients (≥65 years with se-vere chest trauma (AIS≥3 points) (elderly group) treated in Chongqing Emergency Medical Center from June 1995 to May 2005. A total of 1669 patients at age less than 65 years and with AIS≥3 points were set as control group in the same research period (control group). Results The main injury mechanism was blunt trauma, which aceouted for 83.8% (124/148) in elderly group, higher than 69.3% (1 157/ 1 669) in control group (P < 0. 01). The injury causes were mainly traffic accidents, slip and fall from a height. Traffic accidents and slip accounted for 66.2% (98/148) and 14.9% (22/148) respectively, which was significantly higher than 50.6% (845/1 669) and 3.1% (52/1 669) respectively in control group (P < 0. 01). There was no statistical difference upon ISS, RTS, GCS and prehospital time between both groups (all P value > 0.05). The fatality rate and indicence rate of complication in the elerly group were 15.5% (23/148) and 25.7% (38/148), which was significantly higher than 6.5% (108/1 669) and 10.4% (174/1 669) respectively in control group (P <0.01). The fatality rate in elderly group with complications was significantly higher than that in control group (51.7% vs 26.7%) (P < 0.01), while those without complications showed no statistical difference between two groups (6.7% :3.5%) (P >0. 05). Conclusions The patient' s age and complications are relative independent factors to es-timate the trauma care outcome. To raise risk awareness and strengthen the management of complications and supportive treatments for organ function are key to improve survival rate of the elderly patients with se-vere chest trauma.

Objective To explore the feasibility, safety and effectiveness of mobile intensive care and pre-hospital surgical service for patients with severe thoracic injuries so as to further improve success rate of treatment of severe thoracic trauma. Methods A retrospective study was done on the clinical data of 72 patients with severe thoracic injuries (AIS≥3) treated by surgeons from Chongqing Emergency Medical Center (CEMC) from April 1998 to August 2008. The patients were divided into pre-hospital group (n = 36) and in-hospital group (n = 36) according to the time that the definite surgery performed. Results (1) There was no significant statistical difference upon arrival time from scene to primary hospital between two groups (P > 0.05). For patients in pre-hospital group, the time to receive definite surgery was (3.9±4.1) hours, which was significant shorter than (9.6±8.2) hours in in-hospital group (P < 0.05). (2) There were no statistical significant differences upon blood loss volume and blood transfusion volume between two groups (P > 0.05). (3) There was no significant statistical difference upon ISS value between two groups (P > 0.05), but the RTS value of pre-hospital group was significantly lower than that of in-hospital group (P < 0.05). The incidence rate of shock in pre-hospital group was 86.1%, which was significantly higher than 41.7% in in-hospital group (P < 0.05). (4) The percentage of patients who received thoracic close drainage in pre-hospital group was 16.7%, which was significantly higher than 5.6% in in-hospital group. There was no significant statistical difference upon thoracic close drainage plus thoracotomy, thoracic close drainage plus laparotomy and thoracic close drainage plus other operations between two groups. However, the operative rate of thoracic close drainage plus thoracotomy for penetrating injury was 4.8 times higher than that for blunt injury in pre-hospital group, and 1.9 times higher than that for blunt injury in-hospitai group. The operative rate of thoracic close drainage plus laparotomy for blunt injury was 5 times higher than that for penetrating injury in prehospital group, and 4.5 times higher than that for penetrating injury in in-hospital group. The overall survival rate was 95.8% (69/72). Five of eight moribund patients were saved in pre-hospital group, the prevented death rate accounted for 13.9% (5/36) in this group. Conclusions It is flexible, safe and effective to implement mobile intensive care and definite lifesaving surgical interventions for patients with severe thoracic injuries in primary hospitals. After the condition of the patient is stabilized, a quick transportation of the patients to a higher level trauma centers (hospitals) for further treatment may reduce the pre-hospital death rate.
