BACKGROUND: The maximal problem of patient with serious hepatitis and surgical doctor is whether they can get donator and rational therapy timely. Looking for the suitable preoperative therapy method to enhance the success rate of operation and improve patient's prognosis is the focus of this domain.OBJECTIVE: To investigate the therapeutic effect of artificial liver support system (ALSS) combining with allotransplantation of the liver on patients with serious hepatitis.DESIGN: Retrospective case analysis. SETTING: Organ Transplantation Center, the Third Affiliated Hospital of Anhui Medical University.PARTICIPANTS: Five male patients with serious hepatitis who underwent allograft liver transplantation were selected from Organ Transplantation Center, the Third Affiliated Hospital of Anhui Medical University form June 2004 to May 2005. Their age ranged from 25 to 48 years. Inclusion criteria: The diagnosis was in accordance with phase standard established at the National Infectious Disease and Parasitology Academic Meeting in September 2000; all patients had signs of routine liver transplantation; their patients fiercely requested the operation.METHODS: Plasma exchange (PE) combined with continuous veno-venous hemofiltration (CVVH) technique was used in this study. Donor who supplied lives was from 20-38-year patients. All of them and their family agreed to donate their organ and signed the donate file before operation. All of 5 patients were used classical no-by-pass orthotopic liver transplantation (OLT). MAIN OUTCOME MEASURES: They were follow-up visited for 21-32 months for rechecking liver and kidney function,RESULTS: All of 5 patients' operation was succeeded. One continued coma postoperative and his serum creatinine and urea nitrogen raised up progressively and complicated by pulmonary infection 1 week after operation and died 2 weeks after operation although given medical treatment hemodialysis positively. The rest recovered well. All of them discharged one month after operation smoothly.CONCLUSION: Allotransplantation of the liver is an utilizable method to treat serious hepatitis. ALSS can be used as an effective method of supportive treatment preoperatively.

OBJECTIVETo discuss arthroscopic technique of single Kirschner wire and suture avoiding epiphyseal line fixation for tibial intercondylar eminence fracture and its clinical results.

METHODSFrom May 2008 to December 2012, 21 patients (13 males, 8 females, ranging in age from 6 to 14 years old) with tibial intercondylar eminence fracture were treated arthroscopically with single Kirschner wire and suture avoiding epiphyseal line fixation technique. According to Meyers and McKeever classification, 7 patients were type II, 10 patients were type III, and 4 patients were type IV. Active rehabilitation began at one week after operation. The patients were followed up for 10 to 30 months. X-ray films were taken to evaluate fracture healing at 1, 3, 6 months after operation; range of motion, the anterior drawer test, the lachman test and the Lysholm knee score were used to evaluate clinical effects.

RESULTSAll fractures were healed without displacement at 6 weeks after operation. Anterior drawer test and the lachman test were both negative in all patients at 3 months after operation. Lysholm knee score was 95.5 ±2.5 at 6 months after operation, and postoperative X-ray film did not find epiphyseal line broadening or narrowing.

CONCLUSIONArthroscopic treatment for tibial eminence intercondylar fracture with single Kirschner wire and 8-shaped suture avoiding epiphyseal line fixation technique has many advantages, such as firm fixation,early mobilization, less invasive, less injury of physis and satisfactory effect.

OBJECTIVETo verify the pharmacological hypothesis of prescriptions by studying the targeted distribution of major components in stewed rhubarb in the rat model with acute pancreatitis (AP).

METHODNormal SD rats (control group, n = 5) and the AP model induced with intraperitoneal cerulein (model group, n = 5) were taken as the experimental objects. Rats of the two groups were orally administered with stewed rhubarb granules (20 g x kg(-1)). Their heart, liver, spleen, lung, kidney and pancreas were collected two hours after the administration. Such constituents as emodin, chrysophanol, physcion, rhein and aloe-emodin and their concentrations in each tissue homogenate were detected by high performance liquid chromatography-mass-mass.

RESULTAloe-emodin and physcion in stewed rhubarb whose concentrations in liver and kidney of normal rats were higher than that in pancreatic tissues, while the distribution spectrums and concentrations of the remaining components in pancreatic tissues had no significant difference with that of other organs. The concentrations of emodin, aloe-emodin, rhein and chrysophanol in stewed rhubarb in pancreatic tissues of the AP model group were higher than that in other tissues and organs, while their concentrations in pancreatic, renal and splenic tissues were notably higher than that in the normal group.

CONCLUSIONIn the conditions of AP, effective components in stewed rhubarb show a targeted distribution feature in pancreas, which provides experimental basis for the pharmacological hypothesis of prescriptions.

Objective　To explore the relationship between hemolymph phenol oxidase and the melanization of Plasmodium yoelii oocysts in Anopheles dirus. Methods　An Anopheles dirus-Plasmodium yoelii system was used Anopheles dirus were divided into 3 groups, that is, non-blood-fedding (N), normal-blood-fedding (B) and infected-blood-fedding (I). The activities of MPO and o-DPO in hemolymph from 3 groups were determined with native polyacrylamide gel electrophoresis (PAGE) and density scanning at 5, 7, 11 and 15 d after blood feeding. Results　Both MPO and o-DPO activity were significantly higher in group I than group N and B (P<0.05). But with the melanization of Plasmodium yoelii oocysts, both MPO and o-DPO activity in group I were decreased in comparison with group N, especially on the 15 th day after infected-blood feeding. MPO and o-DPO activity in group B were significantly stronger than those of group N. Conclusion　Blood feeding and infection of Plasmodium yoelii both can activate the cascade. The heamolymph phenol oxidase may play an important role in the melanization of Plasmodium yoelii oocysts in Anopheles dirus.

OBJECTIVETo study the clinical and pathologic characteristics of primary angiosarcoma of breast.

METHODSFive cases of primary angiosarcoma of breast were reviewed. Immunohistochemical study (SP method) for factor VIII-related antigen, CD31, CD34, estrogen receptor, progesterone receptor and c-erbB-2 was performed. The clinical data were also analyzed.

RESULTSAll of the 5 patients had a history of a painless breast lump. Ultrasound examination and mammogram did not reveal any specific findings. Histologically, various degree of cellular pleomorphism was noted. Immunohistochemical study showed a positive expression of endothelial associated antigens of the tumors cells in all the 5 cases. The staining result for estrogen receptor, progesterone receptor and c-erbB-2 was negative.

CONCLUSIONSPrimary angiosarcoma of breast is a rare entity. The diagnosis is rather difficult owing to the lack of specific clinical findings and histological heterogeneity. Application of Positive expression of endothelial associated antigens of the tumors cells is helpful in making a pathological diagnosis morphologically.

Objective To investigate the effect of arctigenin on the apoptosis of FBL-3 cells and its mechanisms.Methods The mouse erythroleukemia FBL-3 cells were taken as subjects.The untreated FBL-3 parental cells were taken as the control group,and the FBL-3 cells treated with 20 mg/L arctigenin for 24 h were taken as the experimental group.The effects of arctigenin on the apoptosis of the mouse erythroleukemia FBL-3 cells were determined by agarose gel electrophoresis and flow cytometry assay.The changes of apoptosis-related genes were analyzed by reverse transcriptase-polymerase chain reaction(RT-PCR).Results The agarose gel electrophoresis results revealed that the " DNA ladder" was displayed in the experimental group compared to the control group.The flow cytometry data demonstrated that the apoptosis number of FBL-3 cells in the experimental group was markedly increased compared to that in the control group (t =60.681,P =0.000).The RT-PCR assay results suggested that the expressions of Bcl-2 and IAP-1 gene were down-regulated in the experimental group compared to the control group (t =14.732,29.702,all P =0.000),while the expressions of Bax and Smac gene were up-regulated(t =6.721,8.499;P =0.003,0.001),but the expression of Bcl-XL did not change(t =0.209,P =0.844).Conclusions Arctigenin can induce the apoptosis of the mouse erythrolenkemia FBL-3 cells.Apoptosis of the mouse erythrolenkemia FBL-3 cells induced by arctigenin may be correlated to the down-regulation of Bcl-2 and IAP-1 and up-regulation of Bax as well as Smac.
