Objective:To construct a vector containing human vascular endothelial growth factor,VEGF 121 (VEGF 121 ) with green fluorescence protein as the reporter gene,and then to observe its expression in osteoblast.Methods:VEGF 121 gene was amplified from foetus brain library by PCR,then ligated with pEGFP-C1 to form recombinant plasmid pEGFP-VEGF and transfected into osteoblast by liposome.The green fluorescence protein expression was observed by fluorescence microscopy and the VEGF expression was last detected by immunocytochemistry and ELISA.Results:VEGF 121 gene fragment was amplified by PCR and ligated to pEGFP-C1,then transfected into osteoblast successfully.The strong expression of green fluorecensce protein was observed by fluorecensce microscopy,and the expression of VEGF protein was detected by immunocytochemistry and ELISA.Conclusion:Recombinant plasmid pEGFP-VEGF is effectivly expressed after being transfected into osteoblast in vitro,which provides theoretical support for further study with its simple and reliable detecting methods.

Objective To explore the role of estradiol decline in the early luteal phase (the 2nd day after oocyte retrieval) in the prediction of in-vitro fertilization outcomes. Methods A total of 236 cases under in vitro fertilization-embryo transfer (IVF-ET)/ intracytoplasmic sperm injection-embryo transfer(ICSI-ET) cycles were included in this retrospective study of their medical records. The cases were divided into three groups according to the levels of estradiol decline on the 2nd day following OPU: group A (n = 70) with the decline rate of less than 70%, group B (n=114) with the decline rate of 70%~80%and group C (n=52) at the decline rate of more than 80%. The comparisons were done among the three groups in terms of the number of oocyte retrieval, the rate of fertilization, the rate of best oocytes and the rate of miscarriage. Results There were no significant differences statistically in the number of oocyte retrieval, the rate of fertilization, the rate of best oocytes and the rate of miscarriage (P > 0.05). But the rates of clinical pregnancy rate in groups A and B were significantly higher than that in group C (68.6% and 68.4% vs. 44.2%) (P < 0.05). Conclusion The levels of estradiol declines in the early luteal phase may be important in the prediction of IVF outcomes.

Total 2625 cases of pulmonary sequestration were collected from literatures of Chinese National Knowledge Infrastructure from 1998 to 2008. The age, gender, clinical symptoms, chest CT scan,chest X-ray findings, lesion location, supplying artery, venous reflux, and preoperative misdiagnosis of 2625 cases were retrospectively reviewed. The male: female ratio of all cases was 1.58: 1. The main clinical symptoms of pulmonary sequestration were cough, sputum, fever, hemoptysis and chest pain, but 13.36% patients were asymptomatic. Chest CT scan showed pulmonary massive lesions (49.00%), pulmonary cystic lesions (28.57%), pulmonary cystic-solid lesions ( 11.57% ), and flaky shadows (7.96%). Pulmonary sequestration mainly located in the lower lobe; 66. 43% located in the left posterior basal segments, and 20. 16% located in the right posterior basal segments. Pulmonary sequestrations were divided into three types, intralobar sequestration (83. 84% ), extralobar sequestration ( 16.03% ), and mixed sequestration (0.13% ). The arterial supply was mainly from branches of thoracic aorta (76. 55% ) and abdominal aorta (18.47%). The clinical manifestations of pulmonary sequestration were various, so the preoperative misdiagnosis rate was as high as (59 ± 20) %. We should take full advantage of clinical symptoms, imaging findings and location characteristics to improve the preoperative diagnosis rate.

Objective To investigate the secondary metabolites of the South China Sea sponge Acanthella cavernosa. Methods The acetone extract of A. cavernosa was purified by repeated column chromatography on silica gel, sephadex LH-20, and high-performance liquid chromatography (HPLC). Structures of the extract were determined by spectroscopic analysis and comparison with previously reported data. Results and Conclusion A total of 7 compounds were isolated and their structures were identified as kalihinene X-Z (1 - 3), (R)-3,5-diethyl-5-((S,E)-2-ethylhex-3-en-1-yl)furan-2(5H)-one (4), methyl(2Z,6R,8S)-4,6-diethyl-3,6-epoxy-8-methyldodeca-2,4-dienoate (5), methyl(2Z,6R,8R,9E)-3,6-epoxy-4,6,8-triethyl-2,4,9-dodecatrienoate (6), and methyl(2Z,6R,8S)-3,6-epoxy-4,6,8-triethyldodeca-2,4-dienoate (7); and compounds 4 - 7 were identified from the genus Acanthalla for the first time.

A high incidence of esophageal cancer exists in China. Surgical resection remains the dominant therapeutic intervention for patients with operable esophageal carcinoma. However, alternative strategies are actively applied to reduce the frequency of post-op-erative local or distant disease recurrence and to prolong survival. These strategies include neoadjuvant and adjuvant therapies. This review discusses the current knowledge, as well as available data and information, with regard to neoadjuvant and adjuvant therapies for patients with locally advanced esophageal cancer.

Objective To study the calculating model of military medical equipment readiness rate and the main affecting factors in order to make a valuable reference to the decision -making of medical organization for the further medical support. Methods Based on analysis of the problems in calculating method of military medical equipment readiness rate at present, a new improved calculating model and the analysis method relating to assigning mission was put forward by combining the technical requirements of GJB5338-2005 and the actual of medical equipment management. The factors affecting readiness rate in process of manufacturing, operation and maintenance support were analyzed. Results A new improved calculating model of military medical equipment readiness rate was established and the evaluating method was made by adjusting those correlated parameters in the calculation formulas. Conclusion The solution of the model is simple and convenient and the analyzing results show that the readiness rate is close to the reality. It is a practical method for achieving quality state information of medical equipment, so it can meet the requirements of military medical equipment organization in peacetime.

Objective To explore the relation between serum Hcy,Cys C levels and type2 diabetic macro-vascular complications and its clinical significance.Methods The serum levels of Hcy and Cys C were measured with immunoturbidimetry in 80 cases of type 2 diabetic patients with macrovascular complications and 80 cases of type 2 diabetes without macrovascular complications,and in 80 healthy subjects which was seleted as control.Results Serum levels of Hcy and Cys C of type 2 diabetic patients with macrovascular complications were (26.42 ± 5.75)μmol/L and (2.30 ±0.40)μmol/L,which were higher than those of patients without macrovascular complica-tions for (15.31 ±3.13)μmol/L and (1.51 ±0.27)μmol/L(t =15.17,14.64,all P <0.05);Moreover,which were also higher than those in the healthy control group for (8.86 ±1.62)μmol/L and (0.85 ±0.14)μmol/L(t =26.29, 30.56,all P <0.05).The serum levels of Hcy and Cys C of type 2 diabetic patients with carotid arteries increased were (32.53 ±6.46)μmol/L and (2.83 ±0.52)μmol/L,which were higher than those of patients without carotid arteries for (18.46 ±3.63)μmol/L and (1.65 ±0.30)μmol/L(t =11.64,12.06,all P <0.05).In patients of type 2 diabetic with macrovascular complications,Hcy was positively correlated with serum Cys C(r =0.617,P <0.05). Conclusion sCD40L and YKL -40 may have important role in the pathogenesis of type 2 diabetic patients with ma-crovascular complications,which can be used as a valuable reference target in the diagnosis and monitoring of vascular complications in elderly type 2 diabetes,and it may be one of the important independent risk factors of patients with type 2 diabetes.
