1.Primary culture and hepatocelluar specific protein expression in human amniotic epithelial cells
Journal of Shanghai Jiaotong University(Medical Science) 2006;0(03):-
Objective To optimize the method of primary culture for human amniotic epithelial cells (AECs) and detect the expression of hepatocelluar specific proteins in AECs. Methods AECs were obtained by collagenase and trypsin digestion method. 10,20,40 ng/mL epidermal growth factor (EGF) and 10 ng/mL basic fibroblast growth factor were added separately to the culture media,inverted microscope was used to observe the cell growth and proliferation,and the optimal condition for primary culture of AECs was obtained. The primary cells cultured without growth factors were served as controls. The expression of hepatocelluar specific proteins such as albumin,cytokeratin-18 (CK-18),alpha-1 antitrypsin (AAT) and alpha-1 foetoprotein (AFP) in cultured cells and histological sections were detected by immunohistochemical staining. Results The AECs available were relatively pure,with only a few mesenchymal cells. EGF of 10 ng/mL was chosen as an ingredient of culture medium as the growth and proliferation of AECs significantly accelerated with 10 ng/mL EGF. The expression of albumin,CK-18,AAT and AFP was detected in amnion tissues and AECs cultured in vitro. Conclusion Collagenase and trypsin digestion method and culture medium with 10 ng/mL EGF are favourable conditions for primary culture of AECs. Hepatocelluar specific proteins are expressed in human amnion tissues and AECs cultured in vitro,indicating that AECs have some characteristics of hepatocytes.

Objective To summarize the perioperative care experience in patients with benign prostatic hyperplasia (BPH) treated by transurethral electrovaporization of the prostate (TVP). Methods A retrospective analysis of 693 cases of BPH treated by TVP from June 1998 to September 2002 was conducted. Results The operation time ranged (25~130) min (mean, 54 min). Four patients intraoperatively presented with the early symptoms of the transurethral resection syndrome (TURS) and were treated promptly, without deaths during operations. Follow-up checkups for (3~9) months in 422 cases showed that, from the preoperative period to the 3rd postoperative month, the I-PSS declined from (24.8?3.2) points to (11.4?1.9) points ( t=5.48; P
4.Evaluation of serum CA125 in literatures of ovarian neoplasms based on evidence-based medicine
Chinese Journal of Laboratory Medicine 2001;0(02):-
Objective To assess the serum CA125 in literatures of ovarian neoplasms based on evidence-based medicine.Methods The relating reports published in the years of 1996—2003 were collected and evaluated according to the evidence-based medicine principles. Main outcomes include design methods,sample screening,establishment of control group,blind method,criteria of diagnostic trials.Results In the reports collected, gold standard was adopted in 62 reports and independent blind method was adopted in 23 reports, criteria of diagnostic trials such as sensitivity, specificity and likelihood ratio were incomplete and there was no descriptions okf potential bias controlling. As for the literatures sharing the same method ,their conclusion did not totally accord with each other.Conclusion There is no evidence to implicate that serum CA125 was considered an independent predictor of the diagnosis of ovarian cancer.

Objective To explore the effects of mechanical ventilation on the treatment of acute severe left heart failure.Methods While the routine drug therapy was used,25 patients with severe acute left heart failure received mechanical ventilation treatment.The changes of their artery blood gas,vital signs and clinical symptom were observed before and after mechanical ventilation.Results The parameters of their blood gas and clinical symptom were dramatically improved after the mechanical ventilation therapy in 21 patients(P<0.01).19 patients were saved successfully and 6 patients died.Conclusion The mechanical ventilation could effectively improve the clinical symptoms and respiratory function of patients with acute severe left heart failure,which is an effective method in the adjuvant treatment of patients with acute severe left heart failure.
6.Meta-analysis of the safety of Yangzhengxiaoji capsule for the treatment of cancer and precancerosis
Chinese Journal of Clinical Oncology 2013;(21):1318-1323
Objective:To evaluate the safety of Yangzhengxiaoji capsules for the treatment of cancer and precancerosis. Methods:Clinical trials and studies were collected by searching Chinese and English databases, including CNKI, WANFANG database, VIP information database, Pubmed, ScinenceDirect Online, and MEDLINE@EBSCO. The clinical data of Yangzhengxiaoji capsule for the treatment of cancer and pre-cancerosis were included. The quality of the included studies was then evaluated. Related data were extracted with reference to Cochrane Handbook 5.0. Afterward, meta-analysis was conducted using Revman 5.0 software. Results:A total of 19 studies focusing on 2 125 patients receiving Yangzhengxiaoji capsules were included and investigated in this meta-analysis. Results showed that the adverse reaction rates of myelosuppression, WBC and platelet decrease, gastrointestinal reaction, nausea/vomiting, and hepatotoxicity were sig-nificantly lower in the trial groups with Yangzhengxiaoji capsule-assisted chemotherapy/radiotherapy than in the control groups with chemotherapy/radiotherapy only (P<0.05). The adverse reaction rates of nephrotoxicity, cardiotoxicity, and neurotoxicity were not statistically different between the trial groups and the control groups (P>0.05). Conclusion:Yangzhengxiaoji capsule could be safely administered to treat cancer and precancerosis.
7.Healthcare Reform should Prioritize Equality while Maintain Efficiency
Chinese Medical Ethics 1994;0(06):-
By equality in the healthcare retorm we mean equal access to healthcare protection.Future reiorm should establish a fair value concept and make great efforts to solve the serious lack of fairness in the current healthcare system.Efficiency in the healthcare refers to not only higher revenue income of medical institutes but also to utmostly meet the citizens" needs for medical service.For the sake of the most cost - effective distribution of the insufficient budgets and medical resources,medical services have to be diversified for an improved efficiency. In the framework of the healthcare reform,relations between equality and efficiency is the unity of opposites,and top priority shall be given to equality while maintain efficiency.

Objective To evaluate the efficacy of endovenous laser treatment(EVLT) plus punctiform stripping therapy for lower extremity varicose veins.Methods Sixty-eight limbs in fifty patients with varicosed vein underwent EVLT plus punctiform stripping therapy in department of vascular surgery of the first affiliated hospital of Anhui medical university.Results All patients were followed for 2~27 months and all the patients had successful occlusions of varicosed veins with no recurrence were observed.Local skin paresthesia were found in 2 patients.No local recurrence and deep vein thrombosis were found.Conclusion EVLT plus punctiform stripping therapy is a simple and effective treatment for lower extremity varicosed veins with fewer complications and recurrences.
9.Evaluation of Chinese cobra venoms in preventing the kidney from ischemia/reperfusion injury
Chinese Journal of Nephrology 2005;0(08):-
Objective To investigate the renal protection of Chinese cobra venoms (CCV) and its mechanism in renal ischemia/reperfusion (I/R). Methods Thirty-two rats were divided into four groups. 0.1% CCV was separately infused into abdominal cavity at 0.5 h, 24 h before reperfusion in group Ⅰ and Ⅱ . Group Ⅲ suffered from kidney I/R was served as pathological control. Group Ⅳ was sham operation group. BUN and Scr were measured before ischemia and 24 h after reperfusion. Complement C3 was observed at 0, 0.5, 2, 24 h after reperfusion. The kidney samples were examined by HE stain under light microscopy. Apoptosis was detected by terminal deoxynucleotidyl transferase mediated dUTP-biotin in situ nick-end labeling(TUNEL). Results Significant histological damage, apoptosis of tubular cell and impaired renal function were found in group Ⅰ and Ⅲ.The above indexes decreased to a less extend in group Ⅱ (P
