Purpose To study the effects of p57kip2, Cyclin D1 on the carcinogenesis and progression of endometrial carcinoma. Meth-ods 100 cases of endometrial adenocarcinoma ( EA) , 20 cases of endometrial intraepithelial neoplasia ( EIN) , 20 cases of hyperpla-sia lesion, 20 cases of endometrial proliferative phase were selected. Different endometrial cells ( well-differentiated endometrial cancer cells Ishikawa, moderately differentiated endometrial cancer cells JEC, poorly differentiated endometrial cancer cells KLE and normal endometrial cells ESC) were cultured. Protein expression of p57kip2, Cyclin D1 was measured by immunohistochemical EliVision meth-ods. The expression of p57kip2, Cyclin D1 protein in different endometrial cells was detected by Western blot. Results The highest expression of p57kip2 protein was in EIN, the higher expression was in endometrial proliferative phase, the low expression was in EA and the lowest expression was in hyperplasia lesions, but only the expression of p57kip2 protein in EIN was higher than that in hyperplasia le-sions (P<0.05). The highest expression of Cyclin D1 protein was in EA and the lowest expression of Cyclin D1 protein was in endom-etrial proliferative phase, expression of Cyclin D1 protein increased gradually in hyperplasia lesions and EIN, p57kip2, Cyclin D1 pro-tein expression in the tissue of EA increased along with the histological grade, all present decreasing trend, but only p57kip2 protein ex-pression related to histological grade ( P<0.05 ) . The highest expression of p57 kip2 protein was in KLE and the lowest expression of p57kip2 protein was in ESC, but only the expression of p57kip2 protein in KLE was higher than that in ESC (P<0.05). The expression of Cyclin D1 in JEC, Ishikawa higher than that in ESC (P<0.05). Conclusion p57kip2, Cyclin D1 are involved in the occurrence and development of endometrial carcinoma, Cyclin D1 is an early event in endometrial carcinoma, but there may also be have abnormal p57kip2 protein by synthesized, synergistically. Cyclin D1 promoting endometrial malignant transformation. Combined detection of p57kip2, Cyclin D1 expression in endometrial carcinoma, to predict the prognosis of endometrial carcinoma has a certain clinical signifi-cance.

OBJECTIVE:To investigate the effects of different operation methods on the residual amount of docetaxel. METH-ODS:60 Docetaxel injections were selected and divided into two groups,i.e. standard operation method was adopted in group A (30 injections),and clinical common operation method was used in group B(30 injections). Docetaxel injections were placed for 5,10 or 15 minutes respectively,and drained. Residual liquid was collected to calculate residual amount. The difference of residual amount,due to preparation method and standing time,were compared between two groups. RESULTS:After placing for 5,10 or 15 min,the volume and amount of residual liquid in group B were significantly higher than in group A(P<0.05). In same group, the volume and amount of residual liquid after placing for 10 and 15 min were all lower than that after placing for 5 min(P<0.05 or P<0.01);the volume and amount of residual liquid after placing for 15 min were lower than that after placing for 10 min(P<0.05). CONCLUSIONS:The standard operation of pharmacy dispensing staff is very important to reduce the residual amount of docetaxel,and guarantee safe,effective and sufficient medication. It is suggested that clinical staff should abide by standard opera-tion method.

Objective To observe the levels of neutrophil CD64 expression in prostatic fluid of patients with chronic prostatitis and different degrees of infection,to evaluate the value of CD64 in diagnosis and treatment of chronic bacterial prostatitis.Methods 100 subjects were divided into two groups according to chronic prostatitis symptom index (CPSI) established by the National Institutes of Health (NIH):CPSI high score group and CPSI low group,bacterial infection group,and 30 healthy controls.CD64 expression of neutrophils in prostatic fluid was detected by flow cytometry and prostate fluid routine microscopy inspection.Results The expression of CD64 in severe group (high score) was (4857.25±278.45) molecules / cell,which was significantly higher than that in the mild group (P＜0.05).There was significant difference between the mild group and the nonbacterial infection group or the healthy control group (P＜0.01).There was no significant difference between nonbacterial infection group and healthy control group.The expression of CD64 was positively correlated with some white blood cells in the bacterial infection group,but not the whole.ROC curve was drawn according to the data of the subjects.When CD64 was 2135.2 molecules/cell,the sensitivity was 92.9％ and the specificity was 91.7％.Conclusion Quantitative detection of CD64 in prostatic fluid can be used as a sensitive index for diagnosis of chronic bacterial prostatitis and has clinical value.

Objective To explore the improving effect of L-leucine on memory impairment in plateau and the mecha-nism. Methods After successfully trained in the 8-arm radial maze,50 male Kunming mice were selected and randomly divid-ed into normoxic control group (NC group),model group,and L-leucine (low,medium and high dose) groups.Animals in L-leu-cine groups were intragastrically given 0.473 g?kg-1 ,0.945 g?kg-1 and 1.89 g?kg-1 L-leucine for 7 days and those in NC and model control groups were administered the same volume of purified water for the same period of time.At the 4th day of the treat-ment,the mice in the model control group and L-leucine groups were placed in a large low-pressure and low-oxygen chamber to simulate low-pressure hypoxic environment of the plateau (7 500 m,3 d).The 8-arm radial maze was used to measure the spatial learning and memory ability of mice and dry-wet method to measure the water content of brain tissue.HE staining was employed to observe the cell morphological changes in CA1 region of the hippocampus.The expression levels of mTOR,P70S6K and 4E-BP1 mRNA in the hippocampus were detected by SYBR Green real-time PCR. Results The reference memory error ( RME) ,total error ( TE) ,testing time ( TT) ,and water content of brain tissue were significantly increased,the neuron injury was exacerbated in CA1 region of the hippocampus,and the expression levels of mTOR and P70S6K mRNA were markedly decreased in model control group when compared with those in NC group (P<0.05 or P<0.01).These indexes,however,were significantly improved in L-leu-cine groups,especially in high-dose group. Conclusion L-leucine can improve memory impairment in plateau,and the mecha-nism may involve the activation of mTOR and its downstream substrates (4E-BP1 and P70S6K).

AIM To observe the changes of blood glucose level, plasma insulin level and liver glycogen content and regulatory effects of rehmannia glutinosa oligosaccharides(ROS) on glucose metabolism in thymectomized rats. METHODS ①Plasma glucose level, liver glycogen content and plasma insulin level of thymectomized rats were determined three,four, eight and fifteen month after thymectomy operation; ②Effects of ROS (250 mg?kg -1 , po ,?60 d) on spleencyte proliferation,blood glucose level,liver glycogen content, plasma insulin level and plasma corticosterone level in thymectomized rats were investigated seven month after thymectomy. RESULTS From 8 months after thymectomy liver glycogen content and plasma insulin level increased in thymectomized rats, though no obvious changes in blood glucose level were found during the experiment; ②Changes of glucose metabolism in thymectomized rats were largely reversed and normalized with ROS: Increased liver glycogen content turned to be normal,increased plasma insulin level,decreased corticosterone level and decreased splenocyte proliferation in thymectomized rats became normal. CONCLUSION Some changes in glucose metabolism are induced by thymectomy in rats, which can be largely reversed by ROS.

Objectives In this retrospective study we investigated the causes of misdiagnosis and incorrect treatment of hepatic cholangiocarcinoma and ways helpful in the improvement of correct diagnosis.Methods There were altogether pathollgy proved 40 cases of hepatic cholangiocarcinoma. The preoperative diagnostic procedures and surgical measurcs adopted were reviewed. Results The primary misdiagnosis rate was 68%. Patients were misdiagnosed as cholelithiasis complicated by intrahepatic inflammatory mass, hepatic abscess, hepatic hydrocyst, and hepatic adenoma;The surgical procedure performed were: choledocholithotomy, hepatophyma incision drainage or liver puncture drainage on B mode ultrasound localization, and hepatic cyst fenestration. Conclusions The hepatic cholangiocarcinoma can mimic many other benign diseases leading to misdiagnosis and improper surgery. Hence clinical features,history and laboratory evidence characteristic of the cancer must be sought preoperatively and intraoperative biopsy should be taken before definite surgical procedure. [

Objective To explore the ideal choice of feeding artery which is used for regional arterial infusion (RAI) in severe acute pancreatitis. Methods Forty-five patients with SAP were treated with RAI. The ideal feeding artery was that can supply entire pancreas according to arteriography and can maximize concentration of drug at pancreatic tissue. The pancreatic arteriography was considered as the final objective evidence for choice. Results (1)Gastroduodenal artery was chosen as feeding artery in forty-four cases, and superior mesenterlc artery was chosen in only one case because of vascular abnormity. (2)According to splenic arteriography, blood of splenic artery was supplied to spleen chiefly, and only partial tail of pancreas was applied by splenic artery. (3)According to celiac trunk arteriography, blood of celiac trunk could be supplied to entire pancreas, but a considerable proportion of the total blood was supplied to spleen through splenic artery and liver through hepatic artery proper.Therefore, the drug utilization index was lower. (4)According to gastroduodenal arteriography, blood of gastroduodenal artery could be supplied to entire pancrea, and almost all of the blood that contains drug flowed into pancreas. Therefore, the drug utilization index was higher. Conclusions Gastroduodenal artery is the ideal choice of artery which is used for regional intra-arterial infusion in sever acute pancreatitis. Pancreatic arteriography should be applied routinely when yever acute pancreatitis was treated with RAI.

SD rats were injected with streptozotocin and fed with high fat diet,used as type 2 diabetic model. Transcription factor Fox01 [in nucleus (15.00±1. 15 vs 6.45±0. 62) %, P<0.05], Caspase-3 [(23.73 ±1.48 vs 6.30±2.20)% ,P<0.01] expressions in pancreatic istet β cells and the positive rate of islet β cells apoptosis[(22.29±1.84 vs 6.25±2.42) %, P<0.01] in diabetic rats were higher than those of control rats. The islet cells which highly expresed Fox01 (in nucleus)and caspase-3 were just the apoptotic islet cells. Therefore,Fox01 may be involved in regulating apoptosis of islet β cells in type 2 diabetes.
