Objective To summarize the nursing care experience for right ventricular dysfunction after orthotopic heart transplantation.Methods Clinical data of 67 patients underwent heart transplantation were retrospectively analyzed from January 2007 to December 2010.Results 58 patients were discharged after they were cured,9 patients died.67 patients were affected by different degrees of increasing central venous pressure (CVP)early postoperation and right ventricular dysfunction,28 cases received extracorporeal membrane oxygenation(ECMO) assistant,6 cases received continuous renal replacement therapy(CRRT).Among 58 discharged patients,the heart function level showed class two in 54 cases and class three in 4 cases.Conclusions After heart transplantation,followed with intensive care and close observation of right heart failure symptoms,providing effective care and support,active prevention and treatment for right heart failure,maintaining vital organs function were key to successful heart transplantation.

Objective To investigate the clinical efficacy of joint-corresponding point selection plus exercise acupuncture in treating acute ankle sprain.Method Enrolled 70 patients with acute ankle sprain were randomly allocated to two groups.The treatment group received joint-corresponding point selection plus exercise acupuncture and the control group,elastic bandage fixation.Both groups were given ice compress,mobilizationand elevation as auxiliary measures.Treatment was provided seven days as one coursefor a total of two courses.The pain, tenderness, swelling andrange of activitieswere scored in the two groups of patients before and after treatment.Thetherapeutic effects were compared.Result The total efficacy rate was 88.6% in the treatment groupand54.3% in the control group.The therapeutic effect was significantly better in the treatment group than in the control group (P<0.01). Joint pain, tenderness, swelling and activity scores decreased in the two groups after treatment (P<0.01). Joint tenderness and activity scores were lower in the treatment group than in the control group after treatment (P<0.01).Conclusion Joint-corresponding point selection plus exercise acupuncture has clinically a marked therapeutic effect on acute ankle sprain.

Through a comparison of the differences between China and Australia in the models of hospital management and the roles of hospital managers, the paper expounds the specific features of the model of “decentralized powers” and “professional presidents” and the model of “centralized powers” and “expert-turned presidents”. It argues that under the pressures of both internal and external changes, including rapid socioeconomic development, the deepening of the health care reform, the effect of China's accession to the WTO on the medical and health industry, the development of a contingent of professional health care managers in China has become an inevitable trend.

Vascularization is the basis of tissue regeneration. To get engineered tissue, it is necessary that timely and enough nutrition be available to the seed cells, especially those within the biomaterials. Therefore reconstruction of blood supply is the key step leading from basic research to clinical application. Thee major methods have been used to reconstruct blood supply: promotion of vessel growth by means of VEGF, combined grafting of vascular endothelial cells and osteoblasts and microsurgical techniques. The microsurgical techniques, such as wrapping around with pedicled fascia flap, wrapping around with vascularized muscle flap and blood vessel implanting, can help reconstruct blood supply when engineered tissue is fabricated. When engineered tissue is used in clinic to repair defects in vicinity, vascularization can be done in the defect area. But when no fascia flap, muscle flap or vessel can be used in the defect area, the local defects can be repaired through reconstruction of vascularized engineered tissue in other areas and through second stage transplantation with microsurgical techniques.

Objective To explore the association between the polymorphism in IL-28B gene and the interferon virological response in HBeAg-posi-tive chronic hepatitis B patients. Methods A literature search was performed on PubMed,web of Science,China Bio Medicine(CBM)and wan-Fang database. The references was screened with the inclusion and exclusion criteria,and then data were extracted and methodological quality of the studies was judged. Statistical analysis was carried out with RevMan 5.3 and STATA 11.0. Results Totally 7 publications were recruited for the study,including 1 345 patients. The meta-analysis showed that there was no significant difference of interferon response between HBeAg-positive chronic hepatitis B patients with rs8099917TG/GG alleles and rs8099917TT alleles (P= 0.20). There was no statistical difference between Rs12979860CC and CT/TT allele for the sustained virological response(P=0.75). Conclusion Our current meta-analysis suggests that there was no correlation of rs8099917,rs12979860 polymorphism in IL-28B with the sustained virological response to interferon in HBeAg-positive chronic hepatitis b.

Objective: To investigate the efficacy of gemcitabine in chemotherapy of cervical carcinoma. Methods:10 untreated cervical carcinoma patients had been divided into two groups,5 cases were treated with neoadjuvant chemotherapy and radiotherapy,others were treated only with radiotherapy. All patients were operated and compared the pathologic changes of cancers. Moreover 3 cases with recurrent tumors had been treated with gemcitabine and other agents . Results: The rate of complete response(CR) was 60% in group of neoadjuvant chemotherapy and 20% in patients with only radiotherapy. Only one case achieved partial response (PR) in patients with recurrence. Conclusion: The neoadjuvant chemotherapy in cervical carcinoma with gemcitabine is helpful for achieving good response .As radiation sensitizer or radio-potentiator,gemcitabine can promote efficacy of neoadjuvant chemotherapy in cervical carcinoma.

Objective: To study the factors relating the prognosis of ovarian granulosa cell tumor and the characteristics of its clinical presentations. Methods: The clinical records and pathological sections of 24 cases with granulosa cell tumor of ovary were reviewed retrospectively. The clinical characteristics, the clinical stage, and the therapeutic programs and the results were summarized respectively. Results:The 5-years survival rate showed that the clinical stage influenced the prognosis of ovarian granulosa cell tumor obviously. Conclusion: The early dection is the major factor which influences the patients' survival rate.

Eighteen Chinese mongrel dogs were divided into 3 groups randomly according to the given environment: normal environment (NE) group, hot and humid environment (HHE) group, heat acclimatization (HA) group. The dynamic changes in the lymphocyte subsets with CD4 + , CD8 + ,CD11a + ,CD11b + expressions and neutrophil with CD11a and CD11b expressions in peripheral blood were detected post trauma using mAb FACS immuno fluerescence technique. In HHE group, there was a temporary increase (1h) and prolonged decrease (10h) in CD4 + subset, with an increase in CD8 + subset (4h later), resulting in final decrease in CD4 + /CD8 + ratio. In addition, CD11a + T cell decreased 8h later, with a mild change in CD11b + subset. The mechanism is unclear presently. Adaptive training seemed to raise the level of CD4 + and CD11a + lymphocyte subsets and suppress the expression of CD8 + subset. The expression of CD11a and CD11b in NE group increased immediately after injury, presenting a second peak at 4h. The second peak with a higher level was also observed in HHE group, but its duration was shorter than that of the NE group. Heat acclimatization lowered the level of the second peak, though it was remarkably prolonged. Changes in lymphocyte subsets and adhesion molecules of neutrophil suggested that hot and humid environment might suppress the immunity after gunshot injuries, while adaptive exercise could blunt the immunosuppressive response.

To explore the effect of heat acclimatization to the content of SOD and MDA in dogs with gunshot wound in limbs in hot and humid environment, eighteen Chinese mongrels were divided into 3 groups randomly according to the given environment: heat acclimatization(HA) group, normal environment(NE)group, and hot and humid environment(HHE) group. The contents of superoxide dismutast(SOD) and malonaldehyde(MDA) in muscle tissues of the gunshot wound track were assayed at 0, 1, 3, 4, 6, 8, 10, 14, 18 an 24h respectively after wounding. The results showed that the contents of MDA in both HA and HHE groups began to ascend on postinjury hour(PIH) 1, peaking at PIH10 in HA group and PIH6 in HHE group, with the former lower than the latter. There was no significant difference between the contents of MDA in the three groups at PIH18. The content of SOD in HA group began to rise immediately after injury, which was 1h earlier than that in the other two groups, and it was higher than that in HHE group after PIH4. The content of SOD was too low to be measured at PIH10 in HHE group, and this result was 4h earlier than that in the other two groups. In conclusion, SOD and MDA play an important role in the pathophysiological process of gunshot wound in hot and humid environment. Heat acclimatization can be favorable to mitigate pathophysiological changes, and it might be an effective method to prevent rapid deterioration of gunshot injuries in hot and humid environment.
