With the wide development of intra-arterial thrombolysis,the risk factors and the occurrence mechanism of hemorrhagic transformation have drawn great attention.Hemorrhagic tramformation is the most dangerous complication of intra-arterial thrombolysis.The understanding of the occurrence mechanism of hemorrhagic transformation from macroscopic tO microscopic,it is attributed ultimately to the destruction of vascular wall structure or function.The related mechanisms include oxidative stress reaction,leukocyte infiltration and inflammatory reaction,vascular reaction,and extracellular proteolysis.

Objective To investigate the efficacy of ultrasound guided injection of embryonic inactivation in the treatment of ectopic pregnancy.Methods Eighty cases of ectopic pregnancy were selected in the Second Hospital Affiliated to Fujian Medical College from June 2011 to June 2014, in accordance with the order of admission, they were divided into two group of each 40 cases.The control group carries on the conservative treatment, intramuscular injection of methotrexate (MTX) , while the observation group in transvaginal ultrasonography guided implantation of MTX.The curative effect of two groups was Compared.Results The observation group effective rate of the treatment was 92.5％ (37/40), significantly higher than that of control group(62.5％ (25/40) ,x2=10.32 ,P＜0.01).The patients of two groups with no due mass rupture and transit operation.The observation group mass less than or equal to 2 cm disappear time required was (15.4±2.6) d,significantly shorter in the control group((27.1±3)d,t=18.64,P＜0.01).Serum β-human chorionic gonadotropin decreased to normal time required was (13.7±6.1)d, significantly lower than that of the control group((18.4±7.2) d,t=3.15 ,P＜0.01).The adverse reaction rate in the observation group was 10％ (4/40), significantly lower than that of the control group (32.5％ (13/40), P =0.028).Conclusion Ultrasound guided injection of embryonic inactivation treatment for ectopic pregnancy have curative effect, can effectively improve the clinical symptoms and reduce adverse reaction.

Objective To evaluate the clinical efficacy of different treatments on non-small cell lung cancer (NSCLC) patients with brain metastases and to explore the influential factors of the prognosis.Methods The NSCLC patients with brain metastases treated from Jan.2010 to Dec.2011 were follow-up.The survival time and influences resulted from the treatments were analyzed.Results The average survive time of these patients was (11.93±5.53) months,and the median survive time was 11 months.The 6-month,1-year and 2-year overall survival rates were 90.7 ％,41.1％ and 6.4 ％,respectively.Multivariate analysis showed that control of extracranial lesions,Kamofsky score,target therapy and age were independent predictive factors of survival,and the OR value were 0.358 (95 ％ CI0.217-0.593),0.302 (95 ％ CI 0.182-0.502),0.170 (95 ％ CI 0.098-0.296) and 1.635 (95 ％ CI 1.010-2.647),respectively (all P ＜ 0.01).Conclusions Radiation therapy is an effective treatment on non-small cell lung cancer with brain metastases.Biological target therapy can effectively improve survival.The survival time also is correlated with age,Karnofsky score and control of extracranial lesions.

Objective To investigate the short-term clinical efficacy and complication of esophageal cancer patients with two-field lymph node dissection by thoracolaparoscopic esophagectomy surgery and open surgery. Methods One hundred and fifty esophageal cancer patients with two-field lymph node dissection were selected, and they were divided into control group (using open surgery, 75 cases) and observation group (using thoracolaparoscopic esophagectomy surgery, 75 cases) by random digits table method. The operation time, bleeding amount, hospital staying time, number of lymph node dissection, reoperation rate, intensive care unit (ICU) transferring rate and postoperative complication were compared. Results There was no statistical difference in operation time between 2 groups ( P>0.05). The bleeding amount and hospital staying time in observation group were significantly lower than those in control group: (210.33 ± 30.71) ml vs. (254.59±35.28) ml and (8.45±1.52) d vs. (11.61±2.08) d, there were statistical differences (P<0.05). The number of chest lymph node dissection in observation group were significantly higher than those in control group:(17.20±4.06) pieces vs. (10.44±2.65) pieces, and there was statistical difference (P<0.05). There were no statistical differences in reoperation rate and ICU transferring rate between 2 groups ( P>0.05). There were no statistical differences in incidences of hoarseness and anastomotic stenosis between 2 groups ( P>0.05). The incidences of pulmonary infection and arrhythmia in observation group were significantly lower than those in control group:17.33%(13/75) vs. 30.67%(23/75) and 2.67%(2/75) vs. 14.67%(11/75), and there were statistical differences (P<0.05). Conclusion Compared with open surgery, thoracolaparoscopic esophagectomy surgery with two-field lymph node dissection for esophageal cancer patients can effectively reduce the degree of operative trauma, accelerate postoperative rehabilitation process, improve the effects of lymph node dissection, and reduce postoperative complication risk.

Objective To investigate the expression of integrin α6 mRNA in skin lesions of patients with condyloma acuminata. Methods Sixty outpatients with condyloma acuminate, including 30 primary cases and 30 recurrent cases were enrolled in the study;30 non-condyloma acuminate patients undergoing circumcision were used as normal controls. The expression of integrin α6 mRNA in condyloma acuminata lesions of primary and recurrent cases, as well as in skin samples of normal controls were determined by RTPCR. ANOVA was used to compare the differences among the groups, and Student-Newman-Keuls test(q test)was used for pairwise comparisons. Results Relative contents of integrin α6 mRNA(integrin α6/GAPDH)in normal controls, primary and recurrent condyloma acuminata lesions were 0.25±0.10, 0.79±0.16 and 1.07±0.29, respectively, and the difference was of statistical significance(F=127.687, P=0.001). Conclusion Integrin α6 may be associated with the pathogenesis and recurrence of condyloma acuminate, which may provide a new target for prevention and treatment of the disease.

Objective To assess polymerase chain reaction(PCR)combined with restriction fragment length polymorphism(RFLP)and gene sequencing technologies in the detection and typing of HPV DNA.Methods Tissue specimens were collected from skin diseases and venereal disease in perianal or genitals.PCR was performed with HPV DNA general primers(MY09/11)in tissue samples. Positive fragments of HPV DNA were purified and digested by restriction enzymes.The digested fragments were typed by po]yacrylamide gel electrophoresis(PAGE).The Resultswere verified by direct sequencing.Results In 50 clinical samples there were 35 HPV DNA positive,including 26 from patients with condyloma acuminatum,8 from patients with bowenoid papulosis,and 1 from patients with squamous cell carcinoma.In HPV DNA positive samples,19 were HPV6,3 were HPV11,8 were HPV16,4 were HPV6 and HPV 11,and I was HPV62.Sequencing Resultswere in accordance with the PCR-RFLP Results .Conclusion PCRRFLP method is effective in the detection and typing of HPV DNA.

Objective To investigate the clinical value of splenic autotransplantation in patients with severe splenic trauma. Methods A prospective case-control study were performed in 120 patients with traumatic spleen rupture including the treatment group 72 patients and the control group 48 patients. The treatment group were treated with splenectomy plus spleen autotransplantation and the control group merely under splenectomy. Compare the operation time,operative blood loss,postoperative hospital stay,postoperative complications and the immune indexes before and different period after operation. Results Autologous spleen transplantation takes more time than merely splenectomy(P<0.05),but the operative blood loss,postoperative hospital stay and postopera-tive complications were no significant difference. 1 days after operation,the immune indexes of two groups were significantly lower than those before operation(P < 0.05),and 1 week after operation the immune indexes of two groups were significantly elevated(P<0.05).The immune indexes of the treatment group were better than those of the control group 3 months after operation(P < 0.05),and there was no significant difference compared with preoperative. Conclusion Splenectomy cause the decrease in the immune function,but the immune function can quickly rise to a certain level in short term.The splenic autotransplantation can effectively restore the immune func-tion to the preoperative level.
