Objective To evaluate the value of MRI used in the shoulder pain. Methods 34 cases with complaint of shoulder pain underwent MR scanning, the findings of both MRI and surgery were analyzed comparatively.Results MRI of shoulder in 34 cases showed full-thickness and partial-thickness tears of the rotator cuff, tendinitis, glenoid labrum tear, synovitis, biceps tendinitis, biceps dislocation and tumors. In 13 patients received arthroscopy or operation. MR findings of 11 cases were correlated to surgical result, one case diagnosed as tendonitis by MRI was showed partial-thickness tears of the rotator cuff during operating, one case in which the MRI showed normal was found biceps tendonitis by arthroscopy. Conclusion MRI can show complex anatomy of shoulder and has high accuracy in diagnosis of shoulder pain, it is a value method for shoulder pain.

[Summary] With the rapid development of endoscopic thyroidectomy for its advantages of hidden incision and good cosmetic effects, it becomes a significant issue to reduce surgical adverse effects.Recurrent laryngeal nerve ( RLN) injury is among the most important complications and is paid much attention to by clinical researchers.Reasons leading to RLN injury include accidental injury, ligation and intraoperative blood loss. An appropriate way to expose RLN, skilled operation performance, precise anatomy, individualized operation scheme and intraoperative neuromonitoring can prevent RLN injury.

BACKGROUND:Hepatocyte transplantation can improve biochemical parameters and survival of animals with acute liver failure.However,cell sources.immunological rejection,distribution and histomorphological alternation of transplanted hepatocytes are important issues for its wide application in clinic.OBJECTIVE:To observe early-stage histomorphological and ultrastructural changes of SV40LT antigen gene transfected hepatocytes after transplanted into rat spleen.DESIGN,TIME AND SETTING:Randomized controlled animal trial was performed at Laboratory of National Hepatobiliary and Enteric Surgery Research Center.Ministry of Health from March to December 2001.MATERIALS:Sixty male Wistar rats were selected for hepatocyte transplantation.METHODS:Sixty rats were randomly divided into 4 groups(n=15).Primary cell group and primary cell plus cyclosporine A group were intrasplenically transplanted with primarily cultured hepatocytes;SV40LT antigen gene group and SV40LT antigen gene plus cyclosporine A group were intrasplenic transplanted with SV40LT antigen gene transfected hepatocytes.Twenty-four hours before and 14 days after transplantation,the rats in primary cell group and SV40LT antigen gene group were injected with 0.5 mL normal saline through tail vein daily,while the other groups were injected with cyclosporine A (10mg/kg per day).MAIN OUTCOME MEASURES:The spleen of one rat was harvested every day postoperatively for light microscopic and electron microscopic examinations to observe survival rate,histomorphological and ultrastructural features of transplanted hepatocytes for 14 days.RESULTS:Compared with primary cell group and SV40LT antigen gene group,the survival rate of transplanted hepatocytes in the other groups was significantly increased(P<0.05),but the histomorphological and ultrastructural changes were minor.There were no significant differences in the survival rate between SV40LT zntigen gene transfected hepatocytes and primarily cultured hepatocytes during the first week after transplantation(P>0.05),while the survival rate in SV40LT antigen gene transfected hepatocytes was significantly higher than primarily cultured hepatocytes 8-14 days postoperatively(P<0.01).CONCLUSION:Under treatment of cyclosporine A,the SV40LT antigen gene transfected hepatocytes can maintain a stable ultrastructure and a long survival rate.

BACKGROUND: Hepatocyte transplantation can improve biochemical parameters and survival of animals with acute liver failure. However, cell sources, immunological rejection, distribution and histomorphological alternation of transplanted hepatocytes are important issues for its wide application in clinic. OBJECTIVE: To observe early-stage histomorphological and ultrastructural changes of SV40LT antigen gene transfected hepatocytes after transplanted into rat spleen. DESIGN, TIME AND SETTING: Randomized controlled animal trial was performed at Laboratory of National Hepatobiliary and Enteric Surgery Research Center, Ministry of Health from March to December 2001. MATERIALS: Sixty male Wistar rats were selected for hepatocyte transplantation. METHODS: Sixty rats were randomly divided into 4 groups (n=15). Primary cell group and primary cell plus cyclosporine A group were intrasplenically transplanted with primarily cultured hepatocytes; SV40LT antigen gene group and SV40LT antigen gene plus cyclosporine A group were intrasplenic transplanted with SV40LT antigen gene transfected hepatocytes. Twenty-four hours before and 14 days after transplantation, the rats in primary cell group and SV40LTor antigen gene group were injected with 0.5 mL normal saline through tail vein daily, while the other groups were injected with cyclosporine A (10 mg/kg per day). MAIN OUTCOME MEASURES: The spleen of one rat was harvested every day postoperatively for light microscopic and electron microscopic examinations to observe survival rate, histomorphological and ultrastructural features of transplanted hepatocytes for 14 days. RESULTS: Compared with primary cell group and SV40LT antigen gene group, the survival rate of transplanted hepatocytes in the other groups was significantly increased (P 0.05), while the survival rate in SV40LT antigen gene transfected hepatocytes was significantly higher than primarily cultured hepatocytes 8-14 days postoperatively (P

Objective To investigate the clinical value of improved percutaneous tramhepatic cholangiographic drainage(PTCD)and percutaneous placement of biliary metallic stents on the treatment of malignant obstructive jaundice.Methods Thirty three patients with malignant biliary obstruction were treated by the improved PTCD guided by ultrasound followed by pereutaneous placement of biliary tract metallic stcnts 1～3 weeks later.Results Improved PTCD WaS succeeded in all the patients,30 patients(90.9%)accepted percutaneous placement of biliary metallic stents successfully,3 patients who failed in stents placement accepted PTCD again for palliative management of iallndice.Thofle who failed in stent placement were found to have bleeding from the PTCD tube,but recovered several days later.Jaundice alleviated in all the patients.The patients were followed up for 1～29 months,medium follow-up period is 14.8 months.Six cases were found lever and jaundice,among that,two ageepted improved PTCD again,one recovered after antibioic treatment,the remaining 3 patients failed in further treatment due to the metastasis of the tumor.Condusion Pereutaneous placement of biliary metallic stents after improved PTCD is a safe and effeetive method to relieve malignant biliary obstruction,it can improve life quality,prolong survival time.This method could be a good choice for treating the patients with mnlignant biliary obstruction without operation.

Objective To summarize the experience of diagnosis and treatment of solid-pseudopapillary tumor of pancreas (SPTP).Methods The clinical data of 15 patients with SPTP who were treated in our hospital from March,2003 to March,2006 were analyzed retrospectively.Results The 15 cases were all women, and the average age was 29.4 years.The chief manifestations were abdominal mass, abdominal pain or other abdominal discomfort. None of the 15 cases had history of pancreatitis or abdominal trauma, and no long history of drinking or smoking. Six cases were negative for CEA,CA50,CA199,CA125 and other tumor markers.Solid and solid-cystic masses in pancreas or solid and solid-cystic tumors in retroperitoneum were found both by B-mode ultrasonography and CT examinations. Preoperative fasting blood sugar was within normal limits. The tumor in 8 cases was located in the pancreatic head, in 6 cases was in the body and tail of pancreas, and in 1 case was in the neck of pancreas. The diameter of the tumors was 2.5-10 cm. No metastasis was found in the abdominal cavity or liver. Local excision was performed in 6 cases, distal pancreatectomy was performed in 5 cases, including 2 cases combined with splenectomy, and pancreaticoduodenectomy was performed in 3 cases, segmental pancreatectomy was performed in one patient with tumor in the neck of pancreas. The 15 cases showed typical pathologic manifestation of SPTP by microscopy. At followed up for 16-52 months, no evidence of recurrence or metastasis in these cases was found.Conclusions Solid-pseudopapillary tumor of pancreas primarily affects young women, and it may be located in any part of pancreas. Surgical resection is recommended as the treatment of choice, and the prognosis is good.

Objective To investigate the effect ot ionizing radiation (IR) on the expressions of HMGB1 in the radiation-sensitive and radiation-resistant human cervical cancer cells and to analysis the role of HMGB1 in the regulation of radiosensitivity.Methods Human cervical cancer cells HeLa and its radioresistant strain HeLaR cells were irradiated with different doses of X-rays.The cells were collected at different time points after irradiation.The expressions of protein and mRNA of HMGB1 were detected by Western blot and real-time quantitative PCR.Results At the protein level,the expression of HMGB1 in HeLaR cells was significantly reduced at 6-36 h after 2,5 and 10 Gy X-ray irradiation (t =3.574-9.754,P ＜0.05),and then it was recovered to the control level at 48 h after IR.On the contrary,the expression of HMGB1 in HeLa cells was significantly increased at 6,12,48 h after 2 Gy IR (t =3.945-4.864,P＜0.05),at 6,36,48hafter5 GyIR (t=-2.875-3.295,P＜0.05),and at 36,48 h after 10 Gy IR (t =-4.480,-4.517,P ＜ 0.05).At mRNA level,the trend of HMGB1 expression alteration was consistent with that of protein expression.Conclusions The changes of HMGB1 expression can be differently induced by X-rays in the human cervical cancer radiation-sensitivity cells and radiation-resistant cells.HMGB1 may be involved in the radioresistance of human cervical cancer.
