1.Analysis of heart rate variability in the patients with malignant tumor of different phases
Fudan University Journal of Medical Sciences 2009;36(4):413-416
Objective To evaluate the clinical practical value of the heart rate viability test in the patients with malignant tumor during their therapies. Methods Totally 187 cases were analyzed and were divided into three different groups, which included 90 malignant tumor patients before therapy, 45 patients with chemotherapy and 52 non-malignant tumor cases (control group). We compared four HRV indexes(ASDNN5,SDANNS, SDNN and RMSSD) of the patients between the different groups as well as inside each group. Results There were statistical significances in the indexes of ASDNN5, SDANN5 and SDNN of patients at different stages before therapy, the three indexes of the stage Ⅲ group were lower than those of the stage Ⅰ group and the control group as well. The three indexes of the stage Ⅳ group compared with the stage Ⅰ group or the control group (P<0.05) were lower either. There was also statistical significances in SDNN between the stage Ⅲ and the stage Ⅱ of the before-therapy group (P< 0. 05). The indexes of SDANN5 and SDNN of the stage Ⅳ in the chemotherapy group were lower than those of the same stage in the before-therapy group(P<0.05). Conclusions The later the stage of malignant tumor patients is, the more the index of HRV declines. Chemotherapy may affect autonomic nerve function of stage Ⅳ patients with malignant tumor and decrease their HRV.

3.Epithelial cells-stem cells interactions in wound healing
Chinese Journal of Tissue Engineering Research 2010;14(6):1092-1096
BACKGROUND: At the process of wound healing, the epithelial cells and epidermal stem cells interactions is complicated which promoting the mechanisms of wound healing. The abnormities of any fine phase can be result in delayed healing or scarring. OBJECTIVE: To summarize the characterization of epithelial cells and epidermal stem cells and their interaction in wound healing so that we can recognize the mechanisms of scarring from histomorphology, biochemistry and molecular variations. METHODS: A computer-based online search of Pubmed Database was undertaken to identify the relevant articles on epithelial cell and epidermal stem cells interactions in wound healing and results in scarring published from 1974 to 2009 with the key words of "epithelial cells, epithelial stem cells, wound healing, keratinocytes, fibroblasts, hypertrophic scar, keloid" in English. At the same time, Chinese relevant articles were searched in China Journal Full-text Database (CJFD) published between 1999 and 2009 with the same key words in Chinese. A total of 43 articles were collected about the cell structure (3 articles), the cell interactions in wound healing and scarring (16 articles), the relevant on epithelial stem cells (24 articles).RESULTS AND CONCLUSION: The effect of different cells in epithelial tissue is known to all. The keratinocytes and fibroblasts had been on studying frequently, and their closely correlated to scarring. At present, the epithelial stem cells has been confirmed, but the relevant on their location, quality and specific epidermal markers are unclear which need to study and explore. With the rapidly development of science and technology, we maybe control the expression of cells by genic regulation not only culture the cells of our need but to prevent the scarring.

6.Influence of maternal H1N1 influenza on perinatal outcomes
Chinese Journal of Perinatal Medicine 2010;13(5):371-374
Objective To discuss the influence of H1N1 influenza on maternal and fetal outcomes and obstetric management. Methods Totally, data were collected on 19 women, affected by H1N1 influenza and admitted to Shengjing Hospital of China Medical University from November 7, 2009 to December 15,2009, and retrospective analysis was performed on the maternal and fetal outcomes. Results Among the 19 cases, three were( 15. 8%, 3/19) in puerperium, who were all mild cases and recovered. Sixteen (84.2%, 16/19)women were diagnosed as H1N1 influenza during pregnancy, among which two in early pregnancy (12. 5%), seven (43. 8%) in mid-term pregnancy and seven (43. 8%) in late pregnancy. According to the severity of H1N1 influenza, six were mild cases (37. 5% ,6/16), two (12. 5% ,2/16)were severe cases and eight (50. 0% ,8/16)were critical. For these 16 pregnant women, thc two cases in early pregnancy (mild cases) were terminated after recovery from H1N1 influenza. Among the seven mid-term cases, four mild and one of the three severe and critical cases delivered till term, and two of the three severe and critical cases were delivered abdominally because of fetal death intrauterine or maternal severe complications at 27 or 23 weeks of gestation. All of the seven late pregnant cases underwent emergent cesarean section due to maternal or fetal reasons, and two fetuses died in the uterus at late pregnancy and five survived including four preterm babies and one full term baby. Altogether, nine cases (56. 3%, 9/16)underwent emergent cesarean section, and six babies born alive and five survived without any symptom of influenza, two women died (10. 5%,2/19) after the operation. Conclusions Pregnant women during late pregnancy infected by H1N1 influenza are susceptible to develop into severe and critical conditions. Termination of the pregnancy in time is effective in both life-saving of the mothers and babies and prevent neonatal infection against H1N1.
7.The development of mechanism and prevention of Adriamycin-induced cardiotoxicity
Cancer Research and Clinic 2008;20(4):285-288
Adriamycin is an effective and broad-spectrum anthracycline antineoplastic agent.However,long-term therapy with adriamycin is associated with a high incidence of cumulative and irreversible cardiomyopathy. Mechanisms about adriamycin-induced cardiotoxieity are complicated, including oxidative stress,mitochondrionopathy,cardiac apoptosis,and so on.For the past few years,a series of measures aye used,which attenuate the cardiotoxicity and uninfluence the antitumor effects.The review focuses on the mechanism and prevention of adriamycin-induced cardiotoxicity in order to improve the long term survival rate of neoplastic patient.
8.Allotransplantation of fetus parathyroid after radiated with 60Co and cultured in nude rats
Chinese Journal of Organ Transplantation 1998;19(1):42-44
Allotransplantation with fetus parathyroids was performed in 4 cases of hypoparathyroidism after the grafts had been radiated with 6 Gy of 60Co and cultured in Balb/c nude rats for 14 davs.The recipients took 4 days of cyclosporine A(dose of 20~25mg·kg-1/d),one day preoperation and 3 days postoperation.The patients were followed up for 5~60 months.Traced observation on the patients'clinical symptoms and signs,the changes in the doses of Calcium and Vitamine D and in the levels of serum Calcium and parathyroid hormone was conducted to determine the grafts'survival.The results were satisfactory with all cases surviving for the follow-up period.It is considered that this method is much better than any we did previously.
9.Prevention of recurrence and metastasis of hepatocellular carcinoma following liver transplantation: a systematic review
International Journal of Surgery 2010;37(5):335-339
At present, about one third organ transplantation recipients were hepatocellular carcinoma (HCC) patients even in the most advanced transplant center in the world. HCC especially the early primary HCC has been listed as one of the indications of liver transplantation(LT) in the most organ transplant center in the world. However, due to the tumor recurrence and metastasis following LT, many patients would be dead following transplantation in about 2 years later. Their five-year survival rate was only 50 percent in benign final phase liver disease patients. The current researches for this phenomenon were still shallow both in mechanisms and treatments. How to prevent tumor recurrence has become serious challenges and must be faced in liver transplantation surgery. Obviously, to discover the molecular mechanisms and predisposing factors of following LT recurrence, to explore appropriate standards for LT in HCC patients and to strengthen perioperative management are the only way for increasing LT efficacy.
10.Thyroid autoimmunity and miscarriage: a meta-analysis
Chinese Journal of Endocrinology and Metabolism 2010;26(3):203-208
Objective To investigate the association between thyroid autoimmunity (TAI) and miscarriage.Methods A systematic review of both case-control and cohort studies on the association between TAI and miscarriage published before March 2009 was performed.All the literatures were abstracted based on the defined selection criteria by two independent investigators.Publication bias was tested by funnel plot.The odd ratios of case-control studies and relative risks of cohort studies were pooled respectively,depending on the result of heterogeneity test among the individual studies.The software Review Manager (version 4.3.1) was used for meta analysis.Results Electronic search yielded 23 articles,4 of which were reviews and were excluded.The remaining 19 clinical studies met the selection criteria,of which 7 were case-control studies and 12 cohort studies.A clear association between the presence of thyroid autoantibodies (TA) and miscarriage was found with a pooled odds ratio of 2.72 (95% CI 1.27-5.80,P = 0.01) in 7 case-control studies,and a pooled relative risk of 2.41 (95% CI 1.96-2.96,P<0.01) in 12 cohort studies.Women with TA were found to have slightly older age (age difference,1.29 years,95% CI 0.43-2.16,P = 0.003) and raised TSH levels (TSH difference,0.61 mIU/L,95% CI 0.51-0.71,P<0.01) compared with those without TA.Conclusion TAI is significantly associated with miscarriage,which can be interpreted as the direct involvement of TA.Alternatively,the association can be partially explained by the slightly older age in women with TA compared with those without.A third possibility is mild thyroid failure,as TSH levels in TA-positive but euthyroid women are higher than in TA-negative women.
