Objective To assess the cesarean section scar morphology and size with transvaginal ultrasound and the healing of incision diverticulum after the repairing operation.Methods Forty cases with cesarean section scar defects needed repairing operation,40 cases of cesarean section without symptoms and 40 cases of vaginal delivery were involved.The scar condition and measured the size of cesarean section defects were observed.For the 40 cases needed repairing operation,the healing of the scar and measured the size of the defects were observed which still existed before and after the surgery.For the transvaginal delivery cases the thickness of uterine isthmus were measured.Results After the scar defects repairing operation,there were 9 cases who still had diverticulum,but the defects were smaller than that before operation (P <0.05).The symptoms were relieved.Among the 40 asymptomatic cases,there were 1 1 cases had defects,but the diverticulum were smaller than that of needed operation patients (P < 0.05 ). Conclusions The transvaginal ultrasound is a noninvasive and convenient method to observe the cesarean section scar.

Objective To observe the expression of fibroblast specific protein-1 (S100A4) in human lung cancer,and investigate roles of S100A4 in the infiltration and metastasis of lung cancer. Methods Immunohistochemical S-P method was used to detect the expression of S100A4 in 50 lung cancer tissues and 6 normal lung tissues. Results The expression of S100A4 was up-regulated in lung cancer tissues.Significant differences of the expression rates of S100A4 was found between lung cancer and normal groups (P

Objective To determine the expression of indole-2,3 dioxygenase (IDO) in human acute leukemia,and to investigate its correlations with clinicopathological parameters and prognosis in acute leukemia.Methods The expression of IDO in protein and RNA levels was detected by immunohistochemistry and real-time quantitative RT-PCR,respectively,and the correlations of IDO with clinicopathologic features and prognosis of acute myeloid leukemia (AML)-M5 were analyzed.Results The positive rate of IDO protein was 63.3 ％ (38/60) in human acute leukemia,while it in AML (34/49,69.4 ％),especially in AML-M5 patients (29/35,82.9 ％),was significantly higher than that of acute lymphoblastic leukemia (4/11,36.4 ％).The expression of IDO protein in healthy human peripheral blood mononuclear cells was negative.The RNA expression level of IDO in AML-M5 or non AML-M5 patients were significantly higher than that of healthy people (P ＜ 0.001),and AML-M5 patients had significantly higher IDO RNA level than that in non AML-M5 patients (P ＜ 0.05).The IDO gene expression was not correlated with sex,age and drug sensitivity,while it was closely related with these factors in the patients without complication of pulmonary infection.IDO could not act as an independent prognostic marker.Conclusion The expression of IDO in AML-M5 patients is significantly higher than that in non AML-M5 patients and healthy people.The positive expression of IDO is associated with poor prognosis of AML-M5 patients,but it is not an independent poor prognostic indicator.

ObjectiveTo analyze the relationship between expressions of Indoleamine 2,3-dioxygenase (IDO) and B7-H1 with clinico-pathological features and their prognostic significance in pancreatic cancer (PC).Method95 patients who underwent radical pancreaticoduodenectomy for PC were studied.The IDO and B7-H1 expressions in tissue specimens were determined by immunohistochemistry.ResultsIDO and B7-H1 expressions were higher in pancreatic carcinoma tissues than in normal pancreatic tissues (P＜0.05).IDO and B7-H1 expressions positively and significantly correlated with pathological grades and tumour-node-metastasis (TNM) stages (P＜0.05).They were prognostic of poor cancer-specific survival.After adjusting by the Cox proportional hazards regression models (P＜0.05),only a combined IDO/B7-H1 expression served as an independent prognostic marker.ConclusionsIDO and B7-H1 were expressed in PC,and they were important markers for malignant progression of PC.A combined IDO/B7-H1 expression served as an independent prognostic marker for PC.

Objective To understand the malaria situation of Shandong Province in 2013,so as to provide the evidence for formulating targeted prevention and control strategy and measures. Methods The data of malaria cases of Shandong Province in 2013 were collected from the Information Management System for Infectious Diseases Report and Information Management Sys-tem for Parasitic Diseases Control and Prevention. The data of epidemiological characteristics of malaria situation and the diagno-sis and treatment of malaria cases were analyzed by Microsoft Excell2007. Results There were 131 malaria cases reported in 2013,all of them were imported cases,and 127 cases(96.95%)were imported from African countries. A total of 116 cases (88.55%)were falciparum malaria cases. Totally 97.71%of the cases were male and the average age of malaria cases was 39 years. A total of 61.83%of the cases were peasants and 65.65%of the cases only received junior high school education. The dis-tribution of malaria cases was concentrated in Tai’an City(32 cases),Yantai City(19 cases)and Weihai City(17 cases),total-ly acounting for 53.13%. There was no significant seasonal variation in the reporting time of the cases. The median time from on-set to seeing doctor was four days and the median time from seeing doctor to being diagnosed was one day. Totally 35.88%of the cases were misdiagnosed when the first visit to a doctor. All of the cases were laboratory confirmed and 100%of them received the standard treatment after diagnosis. Conclusions All of the malaria cases were imported cases in Shandong Province in 2013. To control the imported malaria in Shandong Province,it is necessary to further strengthen the multi-sectoral cooperation, health education,malaria screening and professional training.

Objective To explore the active immunotherapeutic effects of whole-cell leukemia vaccine combined with 1-methyl-tryptophan (1-MT, inhibitor of idoleamine 2,3-dioxygenase, IDO) treatment on leukemia. Methods The tumor-bearing mice model was made by hypodermic injection of FBL-3 cells. Then these mice were divided into 5 groups, normal group, PBS control group, CTX chemotherapy group, vaccine treated group and vaccine combined with 1-MT treated group (1-MT group), respectively. The main outcome measures including general condition, response rate, tumor size, metastasis and survival time were investigated. Results The mice of PBS control group were slow to move and much heavier (including tumor nodules) than the other groups. No obvious difference was observed in activity, eating behavior and weight between normal group, vaccine treated group and 1-MT treated group. The mice of CTX chemotherapy group were observed epilation, arched body and worn, and those weights decreased significantly compared with other group. The treatment-related mortality of vaccine-treated group and 1-MT group was lower than that of CTX chemotherapy group significantly (0, 0 vs 40 %). There were no significant difference in complete remission rates between vaccine treated group and 1-MT group (61.1 % vs 70.0 %, χ2 = 0.221, P >0.05). But the recurrence rate of 1-MT group was lower than vaccine treated group (0 vs 36.36 %). The tumor nodules growth of recurrent mice could be inhibited by 1-MT. The mean survival time of vaccine treated group and 1-MT group were longer than that in CTX chemotherapy group and PBS control group (χ2 = 52.13, P <0.01). Conclusion Whole-cell leukemia vaccine can inhibit tumor growth and prolong tumor-bearing mice survival time with remarkable curative effects and few side effects. Vaccine combined with 1-MT treatment can significantly reduce tumor recurrence rate, and 1-MT was still effective in inhibiting recurrence of tumor nodules growth after vaccine treatment.

Objective To study the surgical diagnosis and treatment of renal tuberculosis(TB). Methods The clinical data of 42 cases with renal TB were analyzed retrospectively and the experiences of clinical diagnostic and treatment were summarized. Results Cystic irritation symptoms(78.6% ,33/42)and gross hematuria(64. 3%,27/42)were the most common symptoms in these patients. Abnormal urine were found in 83.3 % cases. Acid-fast stains on urinary sediment were positive in 28.6%(12/42)of cases. The diagnostic accuracy of B-ultrasonicgraphy,IVU,retrograde pyelography and CT examination in these patients were 19.0%(8/42),33.3% (14/42),26.2%(11/42)and 71.4%(30/42)respectively. Among all cases enrolled in the study,6 patients received antiphthisic medicine treatment,3 of them were cured and the other 3 accepted nephrectomy and partial ureterectomy after 6-12 months because of severe renal function impairment 36 cases received surgical treatment. In the 39 cases treated with operation,all of them were proved to carry renal tuberculosis by the postoperative pathological examinations. Conclusions The medical history,urine analysis,image examination should be considered synthetically in the clinical diagnosis of renal tuberculosis. The patients should be followed up closely during antiphthisic treatment period. Seriously damaged or nonfunctioning kidney should be removed promptly.
