AIM:Recently,amnion transplantation has been one of effective methods for curing corneal alkali burn,but its biomechanism is unclear.This study was to discuss the efficiency of different kinds of amnion on rabbit corneal alkali burn and to find the bioactive functions of the amnion.METHODS:The experiment was carried out in the Central Laboratory of Experimental Animals at Chongqing University of Medical Sciences between January and July in 2004.All the disposals were in accordance with the ethical standard of animals.①Placenta from healthy puerperants underwent uterine-incision delivery were offered by Department of Obstetrics in the First Affiliated Hospital of Chongqing University of Medical Sciences.A total of 45 New Zealand rabbits were used for corneal alkali burn models and divided into fresh amniotic membrane(FAM),glycerin preserved amniotic membrane(GPAM),vacuum xeransis amniotic membrane(VXAM),alcolhol preserved amniotic membrane(APAM) and control groups,every group had 9 rabbits.②The FAM was prepared within 24 hours,and the preserved amnion were transplanted after 1 month.③The corneal opacity and corneal neovascularization were observed everyday during days 2-21 after operation and once every three days after days 21;corneal fluorescein staining was conducted to observe the repair of corneal epithelium on days 14,30,60 after operation;2 weeks,1 month and 2 months after operation,we did histopathological examination and scanning electron microscope observation.RESULTS:Forty-three rabbits were involved in the result analysis.①There were no significant differences in the corneal opacity and repair velocity of corneal epithelium among FAM,GPAM and VXAM,which were remarkably superior to APAM and controls.APAM group and control group had not distinct difference.②FAM had better effects on inhibiting corneal neovascularization than GPAM and VXAM.CONCLUSION:After transplantation,VXAM,GPAM and FAM can all accelerate corneal epithelial healing and lighten inflammation.FAM containing more bioactive materials,plays best.

Objective To compare the effects of fresh amniotic membrane (FAM), glycerol-preserved amniotic membrane (GPAM), alcohol-preserved amniotic membrane (APAM) and amniotic membrane preserved under vacuum drying condition (VXAM) on rabbit corneal alkali burn and to observe the outcomes of the grafted amniotic membrane. Methods Thirty-six New Zealand rabbits were used to establish corneal alkali burn models and then divided into 4 groups according different preserved amniotic membrane they received (FAM, GPAM, VXAM and APAM), with 9 rabbits in each group. After transplantation, we observed the changes of amniotic membrane graft, corneal opacity, corneal neovascularization (CNV) with slit lamp microscopy. The amniotic membrane graft was examined by HE staining 10 d, 14 d and 1 month after transplantation. Results One month later, FAM graft, GPAM graft and VXAM graft showed better curative effect than APAM graft. Ten days after transplantation, the amniotic membrane graft began to dissolve and desquamate, and disappeared completely till 14 d after transplantation. Amniotic membrane tissues were not found under light microscope in any rabbit. FAM graft dissolved most quickly, and APAM graft was the most slowly. The dissolution of GPAM graft and VXAM graft had no significant difference. Conclusion After amniotic membrane transplantation, it dissolves and sheds instead of fusing with recipient tissues. Corneal epithelium grows under amniotic membrane graft. Amniotic membrane graft transplantation should be called as amniotic membrane patching.

Objective To exoplore the causes in healing difficulties of osteoporotic fracture, and to study the feasible approaches and methods for clinical treatment of osteoporotic fracture. Methods Forty female Sprague-Dawley rats, used as donor animals, were divided randomly into ovariectomized (OVX) group and control (CON) group, with each group of 20 animals. OVX group was subjected to bilateral ovariectomy and CON group was subjected to sham operation. Four months after surgery, the rats were sacrificed, and long bones of the extremities were harvested respectively for preparation of bone matrix gelatin (BMG) in terms of Urist's method. BMG implants obtained from OVX and CON rats were implanted into left and right femoral muscle pouches respectively of 17 female SD rats. The host rats were killed after 14-day feeding, and tissue block of BMG implants were removed for histologic study, alkaline phosphatase (ALP) activity, and calcium content (CA) determination, respectively. Results ALP activity of BMG tissue block from OVX group was (7.22? 2.59)U/g, and that from CON group was (12.01?6.18)U/g. Significant difference was found between the two groups (P

ObjectiveTo analyze the relationship between clinical characteristic pathology and prognosis in infant with intra-abdominal solid tumor.MethodsFifty-two infants(less than 1 year old) with abdominal solid tumor from Apr.1998 to Feb.2007 in Shanghai Children's Medical Center and from Jan.2001 to Feb.2007 in Shanghai Xinhua Hospital were reviewed.The history of these children were reviewed.Features and clinical pathology of these children with their prognosis were analyzed and followed up by telephones and children return visit records from 5 months to 8 years.ResultsLess than 1 month,7 cases;1 month to 1 year old,45 cases.Teratoma 23 cases(44.23%),neuroblastoma 9 cases(17.31%),nephroblastoma 6 cases(11.54%),hepatoblastoma 5 cases(9.62%),epithelioid hemangioendothelioma of the liver 3 cases(5.77%),congenital mesoblastic nephroma 3 cases(5.77%),fusiform cell epithelioid hemangioendothelioma of pancreas 1 case(1.92%),hamartoma of the liver 1 case(1.92%),retroperitoneal small cell malignant tumor 1 case(1.92%).Benign:malignant=1:1.Among the benign tumor,male:female=1:1.Among the malignant tumor,male:female=2.33:1.0.All children were treated with tumor resection,and combined with chemotherapy for those whose tumors were malignant.ConclusionsAmong infant abdominal solid tumors,teratoma and neuroblastoma are much more than other tumors.The cases of benign tumors are almost as much as the malignant tumors.The benign tumors did not have sex differences,and had good prognosis after surgical resection.However,in malignant tumors,the incidence rate of male is obviously higher than female.Completely resection of those malignant tumors with chemotherapy would get little incidence of recrudescence and low case fatality rate.Early diagnosis and early treatment play an important role in prognosis.

Objective: Our aim was to investigate the effects of phenylephrine (PH) and angiotensin Ⅱ (AT) on reperfusion arrhythmias in the isolated rat heart and its mechanism. Methods: Isolated rat hearts were subjected to dual coronary perfusion. After 15 minutes of aerobic perfusion of both coronary beds, flow to the left coronary bed infused selectively into that bed. Ventricular tachycardia (VT) and fibrillation (VF) were analyzed 5 minutes after reperfusion. Results: The reperfusion arrhythmias was significantly exacerbated by PH; however, AT alone did not have the same effect. The selective Na+/H+ exchanger (NHE) inhibitor, HOE642, which was infused along with PH, reversed the proarrhythmic effects of PH. The specific protein kinase C (PKC) inhibitor GF109203X (GF) infused along with PH can only partially reverse the proarrhythmic effect of PH. The AT2 receptor inhibitor PD123319 (PD) alone increased the incidence of reperfusion-induced arrhythmias. However, no statistical significance showed. Combination of PD and AT significantly increased the incidence of reperfusion-induced arrhythmias. Conclusion: Activation of α1-adrenoceptor can exacerbate reperfusion-induced arrhythmias. The AT1 receptor activated by AT can exacerbate reperfusion-induced arrhythmias. The activation of AT2 receptor may reduce reperfusion-induced arrhythmias.

Objective :To develop an agent that is more active against receptor-bearing target cells without increasing the toxic effect on non-target cells. Methods :By the use of molecular biology techniques,we designed and constructed a fusion protein 5＇IL6-TNF△ by connecting the human interleukin-6 (hIL-6) gene and a human tumor necrosis factor α derivative (TNF△) gene througha synthetic linker sequence followed by subsequent expression in E. Coli. Results: In cytotoxicity assay with myeloma cell line U266, the normal type of 5＇ IL6-TNF△ showed an antitumor activity 3 times higher than that of TNF△;and the antitumor activity of 5＇IL6-TNF△ blocked by IL-6Rwas only 1/30 of that of normal type of 5＇ IL6-TNF△. Meanwhile,the 5＇IL6-TNF△ blocked by an ti-TNF antibody did not show any cytotoxicity to U266 cells. In activity assay with L929 cells ,the toxic effect of the fusion protein was found 1/22 of that of TNF△. Conclusion: The 5＇IL6-TNF△fusion protein might be a useful cytotoxic agent in cancer treatment.

Objective To evaluate the effectiveness of thoracic electrical bioimpedance(TEB)in monitoring the cardiac function of peritoneal dialysis patients.Methods One hundred and one patients with continuous ambulatory peritoneal dialysis (CAPD) and 30 healthy persons (control group)were included in the study.Thoracic electrical bioimpedance (TEB) noninvasive hcmodynamic monitoring and echocardiography were taken to analyze the correlation between indexes.Results Echocardiography showed that left atrial diameter (LAD),left ventricular end diastolic diameter (LVDd),left ventricular end systolic diameter (LVDs),interventricular septal thickness （IVST),interventricular septal thickness (PAP),left ventricle weight index (LVMI) of CAPD group were higher than that of the control group (all P ＜ 0.05),early and late wave of mitral valve flow (E/A) of CAPD group was lower than that of control group (P ＜ 0.05).TEB monitoring showed that cardiac output (CO),stroke volume (SV),acceleration index (ACI),ejection fraction (EF),velocity index (Ⅵ) of CAPD group were significantly lower than that of control group (all P ＜ 0.01),systolic time ratio (STR),SVR,TFC of CAPD group were significantly higher than that of control group (P ＜ 0.01).Correlation analysis show that left ventricular ejection fraction (LVEF) was negatively correlated with BNP (r =-0.467,P ＜ 0.01),LVMI was positively correlated with BNP (r=0.416,P ＜ 0.01),PEP,STR and TFC were positively correlated with BNP (r =0.404,P ＜ 0.01; r =0.572,P ＜ 0.01; r=0.471,P ＜ 0.01),EF was negatively correlated with BNP (r =-0.664,P ＜ 0.01).Correlation analysis between echocardiogaphy and TEB monitoring index showed there was significant correlation between EF and LVEF (r =0.451,P ＜ 0.01),SVR and TFC were positively correlated with LVMI (r =0.232,P ＜ 0.05; r =0.284,P ＜ 0.05),SV was positively correlated with E/A (r =0.285,P ＜ 0.05),pre-ejection period (PEP) and STR were negatively correlated with LVEF (r =-0.389,P ＜ 0.01; r =-0.446,P ＜ 0.01),TFC was positively correlated with LAD (r=0.279,P ＜ 0.05).Conclusion TEB monitoring can accurately evaluate the cardiac function with the advantage of dynamic monitoring and simple operation.It can partly replace the echocardiography test.

Objective To investigate the renoprective effect and its possible mechanism of Niaoduqing on the adriamycin(ADR)-induced nephropathy rats. Methods Forty eight male Sprague-Dawley rats were randomly divided into normal control(n=12), ADR-induced nephropathy(model, n = 12), Benazepril-treated ADR nephropathy(Benazepril, n=12)and Niaoduqing-treated ADR nephropathy(Niaoduqing, n =12)groups. The rat nephropathy model was established by adriamycin injection and unilateral nephrectomy. The rats were sacrifficed per batch at the 4th and 8th weekend.The pathological change of nephridial tissue, the 24-hour urinary protein excretion and renal function were examined. Immunohistochemistry was used to meassure the expression of fibronection(FN), collagenⅣ(COLⅣ), osteopontin(OPN). Results The 24-hour urinary protein excretion, BUN, Scr, triglyeride(TG), cholesterol(Cho)in model group were significantly higher than those in normal group(P<0.01), as well as more server glomerulosclerosis in kidney were observed in model group than those in control group(P<0.01), while the albumin(Alb)was lower (P<0.01). Compared with model group, the 24-hour urinary protein excretion, BUN, Scr, TG, Cho were significantly reduced and renal glomerulosclerosis was improved in Niaoduqing group(P< 0.01), while the Alb was higher(P<0.01). Conclusion Niaoduqing palys an important role in the prevention and treatment for nephropathy.
