Objective To investigate and analyze the relationship of clinicopathological stages characteristics and surgical proce-dures of perforation of gastric cancer .Methods Data of clinicopathological stages characteristics of 50 patients with perforation of gastric cancer in this hospital were retrospectively analyzed ,and the correlation between of the different clinicopathological stages and surgical procedures was analyzed .Results Fifty patients were with clinical stage Ⅱ - Ⅳ ,there were 2 cases of stage Ⅱ ,19 ca-ses of stage Ⅲ ,29 cases of stage Ⅳ .Surgical approach were simple perforation repair ,palliative surgery ,first radical resection and second radical resection ,and the number of cases were 16 cases(6 cases of stage Ⅲ ,10 cases of stage Ⅳ) ,19 cases(6 cases of stageⅢ ,13 cases of stage Ⅳ) ,4 cases(one case of stage Ⅱ ,3 cases of stage Ⅲ) and 11 cases(4 cases of stage Ⅱ ,7 cases of stage Ⅲ) . Conclusion It indicated that making reasonable choice of surgical approach according to the clinical staging can improve patients′outcomes .

Objective To analyze the multi-slice spiral CT(MSCT) angiographic features of hepatic hemangioma accompanied with peripheral arterial-portal shunt(APS),and to assess the MSCT diagnostic ability and clinical value for peripheral APS.Methods 12 cases of hepatic hemangioma accompanied by peripheral APS underwent triphase enhanced MSCT scan,the images were post-processed with maximum intensity projection(MIP),volume rendering(VR) and then analysed.Results During hepatic arterial phase,the peripheral APS and transient hepatic parenchymal enhancement(THPE) could be visualized on MIP and VR.APS were classified into four types according to the findings on VR and MIP.TypeⅠ: Branch of the portal veins early enhancement in peritumoral wedge-shaped enhanced area,more frequently appeared as parellel track sign;TypeⅡ: Showed early opacification of small portal branchs near tumors,APS more frequently found in peritumoral wedge-shaped enhanced area;Type Ⅲ:Included both typeⅠand typeⅡ signs;Type Ⅳ: Only showed peritumoral THPE.Conclusion MSCT angiography provides a new effective technique for demonstrating and understanding peripheral APS and THPE.

Objective To investigate the effects of high density lipoprotein (HDL) on thrombin-activated platelet al-pha-granulemembrane protein (CD62P) and lysosome intact membrane protein (CD63) expressions in vitro. Methods The equivalent volume of washed platelets prepared by hand was preincubated with HDL (1 g/L) in 37℃water for 15 minutes, which was then stimulated with different concentrations of thrombin (0.5 U/mL, 1 U/mL and 10 U/mL) for 10 minutes in wa-ter of 37℃. Meanwhile another three groups of washed platelets were incubated with thrombin (0.5 U/mL, 1 U/mL and 10 U/mL) for 10 minutes, respectively. The CD62P and CD63 from each sample were analyzed by flow cytometry (FCM). Results The CD62P positive rates of HDL-preincubated groups were significantly lower than those of different concentrations of thrombin groups (0.5 U/mL,1 U/mL and 10 U/mL) in the absence of HDL (11.55%± 1.34% vs 18.14%± 1.50%, 17.19%± 0.17% vs 26.24%± 0.77% and 19.79%± 0.32% vs 80.38%± 5.66%,P ＜ 0.01). Meanwhile, The CD63 positive rates of HDL-preincubated groups were also significantly lower than those of thrombin-treated (0.5 U/mL, 1 U/mL and 10 U/mL) groups without HDL, namely,2.92%±0.22%vs 8.09%±0.48%(P＜0.001), 4.20%±0.98%vs 14.15%±1.39%(P＜0.001) and 5.12%± 0.09% vs 24.48%± 1.71%(P ＜ 0.01). Conclusion HDL inhibits the expression of CD62P and CD63 on throm-bin-stimulated platelets in vitro.

The development and wide application of assisted reproductive techniques(ART) help many couples suffered from infertility and/or sterility to get baby.Meanwhile,the usage of ART led to much ethic problem.We,hence,investigate the strategies to deal with the ethic problem in ART correctly.

Objective To observe the effect of the Intelligent Clinical Gait Evaluation System on hemiplegic gait and walking ability of the stroke patients. Methods 60 patients were divided into training group (n=30) and control group (n=30). The control group received routine rehabilitation training, while the training group received rehabilitation under the Intelligent Clinical Gait Evaluation System. They were evaluated with the Intelligent Clinical Gait Evaluation System before and 6 weeks after treatment. Results The walking ability improved in both groups after training (P<0.05), and improved more in the training group than in the control group (P<0.05). Conclusion Intelligent Clinical Gait Evaluation System can be used to guide the rehabilitation of hemiplegic gait.

Objective To evaluate the effects of an optimized resuscitation bundle on prognosis of emergency patients with septic shock.Methods 65 patients with septic shock,admitted into emergency intensive care unit (ICU),were randomly divided into the treatment group(treated by an optimized resuscitation bundle)and the control group(treated by surviving sepsis campaign classics methods)by using random number table.The scores of sepsis-related organ failure assessment(SOFA) scores,the vasoactive agent application times,the mechanical ventilation times,the stay days of ICU,and 28-day mortality of the two groups were observed and compared.Results 3,7 day after erollment the SOFA score of the treatment group was (9.1 ± 2.5) points,(8.2 ± 2.8) points,respectively,which was lower than that of the control group[(10.1 ± 3.3) points,(9.5 ± 3.1) points] at the same time(t =4.52,3.99,all P ＜ 0.05) ; 8-day mortality rate of the treatment group was 28.1％,which was lower than that of the control group (48.5％) (x2 =12.84,P ＜ 0.05).Conclusion Application of an early optimized resuscitation bundle can significantly improve the prognosis of emergency patients with septic shock.

Objective To evaluate the internal irradiation biological effects of 125I-UdR chitosan nanoparticles in hepatoma cells.Methods The accumulation and distribution of 125I-UdR-CS-DLN in hepatoma cells HepG2 and human liver tissue cells HL-7702 were observed with a confocal microscopy.The internal irradiation biological effects were evaluated by MTT assay,flow cytometry and single cell gel electrophoresis.The apoptosis of in situ rabbit liver tumor treated with 125I-UdR-CS-DLN was assayed by TUNEL staining technique.Results After 30 min of nano-particle treatment,its accumulation in the cytoplasm of HepG2 cells was significantly greater than that in HL-7702 cells.When the concentrations of 125I-UdR-CS-DLN was higher than 37 kBq/ml,the cell viability of HepG2 was significantly lower than that of lL-7702 at 24 and 48 h post-treatment(t =-4.46-6.31,P＜0.05),and the HepG2 cells were arrested at G1 phase and significantly impaired at G2/M phase.In addition,the degrees of DNA doublestrand break of both cell lines irradiated by 125I-UdR-CS-DLN were significantly higher than those treated with 125I-UdR,and the DNA repair capacity of HepG2 cells was significantly lower than that of HL-7702 cells(OTM:t =2.94,P ＜0.05;TDNA％:t =10.64,P ＜0.01).TUNEL staining showed that cell apoptosis could be induced in the rabbit liver carcinoma by 125I-UdR-CS-DLN but not by 125I-UdR.Conclusions The amount of 125I-UdR-CS-DLN absorbed by hepatoma cells is significantly higher than that of 125I-UdR,which suggests that 125 I-UdR-CS-DLN induces more stronger internal radiation biological effects of apoptosis and DNA damage on hepatoma cells.
