Objective The efficacies of nedaplatin-combined chemotherapy were compared with those of cisplatin-combined chemotherapy in patients with advanced malignant tumors. Methods Two hundred and sixty-two patients were divided into two groups randomly, the nedaplatin(NDP) group (M94, F36, median age 58y) and the eisplatin(Cis) group (M95, F37, median age 57y). Cycles were repeated every 4 weeks. Effects were assessed after 2 cycles. First-line schedules were chosen, and nedaplatin and cisplatin were used respectively. Results The results showed that the remission rate (50.8 %) in NDP group was significantly higher than that (40.2 %) in Cis group (P<0.05). The NDP had better efficacy than Cis especially in treating ovary cancer and esophageal cancer. The toxicity of NDP was milder for gastro-intestinal tract but more serious for bone marrow than that of Cis(P<0.01). Conclusion As a new broad-spectrum anti-tumor agent, NDP could be a better choice than cisplatin in the treatment of malignant tumors. It is especially of better efficacy in treating ovary cancer and esophageal cancer, and could be recommended as the first-line drugs.

Objective To investigate the effect of carbon dioxid insufflation on cerebral blood flow (CBF) during laparoscopic cholecystectomy. Methods Thirty patients ASA grade Ⅰ- Ⅱ undergoing laparoscopic cholecystectomy were selected. The values of jugular venous oxygen partial pressure(PjvO2 ) jugular venous oxygen saturation (SjvO2 ), arterial partial pressure of carbon dioxide (PaCO2), oxygen (PaO2) and saturation (SaO2 ) were measured before the insufflation, 10 min and 30 min after the insufnation, respectively. Results Compared with those before the insufflation, SjvO2 and PacO2 were increased significantly, and arterial--jugular venous oxygen content difference (Ca-jvDO2 ) decreased markedly 10 min and 30 min after insufflation (P

Objective To investigate the recurrence and metastasis patterns of gastric cancer after curative resection and to guide target definition of prophylactic radiotherapy.Methods In the past 8 years,130 gastric cancer patients with treatment failure after radical resection were retrospectively analyzed.The failure sites were confirmed by B ultrasonography, CT or MRI imaging.Ten of 28 patients with ascites were found to have adenocarcinoma cells in the ascites.All superficial node and abdominal wall metastases were diagnosed pathologically by biopsy.And 27 patients with gastric remnant and/or anastomotic recurrence were diagnosed pathologically by biopsy.Results Of 130 patients, 53 were presented with multiple recurrences or metastases, 27 with gastric remnant and/or anastomostic recurrence, 28 with peritoneal metastases, 22 with liver metastases, 9 with pancreatic metastases, 60 with abdominal lymph node (LN) metastases, 8 with abdominal wall metastases, 5 with pelvic implantations, 6 with lung metastases, 5 with brain metastases, 5 with bone metastases, 8 with cervical lymph node metastases, 9 with mediastinal lymph node metastases and 8 with other metastases.Of 60 patients with abdominal LN metastases, 35, 16 and 9 had peri-gastric LNs,peri-pancreatic LNs and para-aortic LNs metastases.Abdominal LN metastases were found in 33 from 77 patients with primary gastric fundus or cardiac carcinoma, 20 from 40 patients with gastric body carcinoma,and 7 from 13 patients with pyloric carcinoma, respectively.Conclusions The failure sites of gastric cancer after radical resection are mainly the gastric stump/stoma, peritoneum, liver and abdominal LN.The perigastric, peri-pancreatic and/or para-aortic LN metastases are the most common failure of LNs.Thus, the peri-gastric, peri-pancreatic and para-aortic LN regions and gastric stump/stoma should be included in postoperative radiotherapy, and current chemotherapy is recommended.

Objective:To investigate the incidence trends and clinicopathologic characteristics of papillary thyroid cancer (PTC). Methods:A retrospective analysis was conducting using the following data:3,766 cases with thyroid disease in the People's Hospital of Wuhan University between January 2001 and July 2013;and 977 cases with thyroid cancer in the Hubei Cancer Hospital between Janu-ary 2006 and July 2013. Results:The incidence of thyroid cancer increased significantly since 2008, ranging from 14.94%to 18.10%(P<0.05). In particular, the PTC cases ranged from 85.33%to 90.89%(P<0.05). A total of 1,416 cases were diagnosed as PTC with a male to female ratio of 1:3.75. The positive rate of neck lymph node metastasis (NLNM) was significantly different in terms of gender and age (P<0.05). Significant differences were also found between the unifocal group and the multifocal group;the positive rate of NL-NM was 77.94%in the latter group. The rate of NLNM in PTC was 72.29%, which had higher significance compared with Hashimoto's thyroiditis or with nodular goiter. Conclusion: The incidence of thyroid cancer is increasing. Cases involving males aged below 45 years old and with>1 cm tumor diameter and multifocal PTC are more likely to be complicated with NLNM.

Objective To study the hemoprotective effects of a rotary magnetic field (RMF) to radiation-injured mice. Methods 132 male BALB/c mice were randomly divided into four groups: a normal group (N), a magnetic treatment group (M), an irradiation group(R) and an irradiation combining magnetic treatment group (R + M). Mice in the N group received no treatment. Mice in the R and R + M groups received total body irradiation with 6.0 Gy 60Co γ/rays. Mice in the M and R + M groups were treated with a RMF for one and half an hour at a time, twice a day, totally for 30 days. The survival rate was observed for 30 days. On days 0, 5, 9, 15, 21, 30, the subjects' peripheral blood cells were counted. On day 9, 23 and 30, the number of bone marrow nucleated cells (BMNCs), colony forming unit-spleen (CFU-S), spleen-body ratio, the cell cycle and apoptosis of bone marrow cells were measured. The pathological sectioning of the femur was performed and the expression level of bone morphogenetic proteins (BMP2/4) in the bone marrow was evaluated. Results ①No mice died in the N and M group. The RMF treatment increased the survival rate and survival days among the irradiated mice (P < 0.01). ②The RMF treatment increased the number of blood cells in their peripheral blood of the R + M group. ③The number of BMNCs, CFU-S and the proportation of G2 + M stage in the R + M were markedly higher than that of the R group, but the proportation of the apoptosis was lower than that of the R group on the 9th day (P < 0.05). Furthermore, the spleen index in the R + M group was also higher than that of the R group on the 23rd day (P < 0.05). ④RMF could improve the expression level of BMP2/4 in the radiation-injued mice. Conclusion The RMF treatment had an obvious protective effect against the effects of irradiation and it accelerated the recovery of hematopeiesis and the hematopoietic microenvironment in mouse bone marrow.

Objective To study early treatment strategy for brain hernia combined with hemorrhagic shock and the effect on prognosis of patients with severe head injury.Methods 252 cases of patients with severe head inju-ry and brain hernia combined with hemorrhagic shock in the mergency intensive care unit were divided into the obser-vation group and control group according to the stochastic indicator method,each group in 126 cases.The two group were treated with early treatment strategy and traditional treatment mode,respectively.The advantages and effect of two modes were analyzed.Results The majority of patients had united injury,such as soft tissue injuries,pelvis and spine fractures.There were 136 cases of patients with mild brain hernia and the rate of patients with hemorrhagic shock was 62.30%(157/252).The mortality was 34.13% in the observation group and 48.41% in the control group.There was significant difference(χ2 =5.306,P=0.021).The ratio of patinents with mild disability was 56.35%(71/126) in the observation group and the control group was 35.71%(45/126).The severe disability,vegetative state and death was 43.65%(55/126) in the observation group after the follow-up of 6 months.It was significantly lower than that of the control group(χ2 =5.306,P=0.001).Conclusion The early strategy treatment has a positive effect on reducing the mortality of brain hernia combined with hemorrhagic shock of patients with severe head injury the GOS for the prognosis disability increases significantly.

We established an ELISPOT for bovine interferon-gamma (BoIFN-γ), and applied it in the diagnosis of bovine tuberculosis (bTB). Monoclonal antibodies that can bind with native BoIFN-γ were screened as the coating antibody and detecting antibody. After optimization of detecting conditions including coating antibody concentration, cell number, and detecting antibody concentration, the ELISPOT assay was established. Peripheral mononuclear cells (PBMCs) isolated from 30 cows were co-cultured with PPD, and detected with the ELISPOT assay. The optimal conditions of ELISPOT assay were 2.5 μg/mL coating antibody 2G5, 2.5 x 10(5) cells/well, and 1 μg/mL detecting antibody Bio-5E11. In these 30 cows tested both with the ELISPOT assay and the BOVIGAM kit, 11 cows were proved to be positive in ELISOPT assay with the sensitivity of 78.6%, and 12 cows were proved to be negative in ELISOPT assay with the specificity of 75%. The ELISPOT assay for BoIFN-γ could be used to detect bTB efficiently and it might be an alternative method for the diagnosis of bTB.

PURPOSE: The purpose of this study was to test the reliability and validity of the Behavior Assessment for Children (BAC) in a community of school-aged children in Taiwan. METHOD: A school-based sample comprising third grade and fourth grade students was recruited from Taichung City in Taiwan. The parents (n = 248) and teachers (n = 15) of these students completed structured questionnaires, including the Child Behavior Checklist (CBCL) and the proposed BAC. Content validity, concurrent validity, construct validity, internal consistency, and inter-rater reliability of the BAC were assessed. RESULTS: The BAC comprised three subscales (attention, emotion, and self-control) that included 17 items. The content validity index (CVI) score was 0.98. The result of the confirmatory factor analysis (goodness of fit = .90, root mean square of residual = .03, root mean square error of approximation = .06, and comparative fit index = .94) supported the construct validity of the three BAC subscales. The concurrent validity of the BAC subscales significantly correlated with the compatible CBCL subscales (r = .59-.78, p < .001). Cronbach α of the subscales of the BAC ranged from .78 to .92. The intraclass correlation coefficient between the parents and teachers ranged from .31 to .44, and the joint probability of agreement ranged from 31.4% to 92.2%. CONCLUSIONS: The BAC is a valid and reliable instrument for evaluating behavioral problems in schoolaged children.

OBJECTIVETo investigate the efficiency of blockage of constitutively activated STAT3 signaling by small interfering RNA (siRNA), and to explore the inhibitory effects on the proliferation of human esophageal squamous carcinoma cells (EC9706 and Eca109).

METHODSEC9706 and Eca109 were transfected with chemical synthesized STAT3 siRNA (100 nmol/L). RT-PCR and Western blot were used to detect STAT3 mRNA and protein expression, including phosphorylated-STAT3 (p-STAT3) before and after the transfection respectively. The changes of DNA-binding activity and cell proliferation were evaluated by electrophoretic mobility gel shift assay and MTT, respectively. Stages of cell cycle were determined by flow cytometry.

RESULTSExpression levels of STAT3 mRNA and STAT3, p-STAT3 proteins were progressively inhibited by STAT3 siRNA at various time points after transfection. STAT3-DNA-binding activity was suppressed after transfection evidenced by electrophoretic mobility gel shift assay. The cell cycle was arrested at G(0)/G(1) phase along with a significant inhibition of cell proliferation after STAT3 siRNA treatment.

CONCLUSIONSTAT3 siRNA specifically and efficiently blocks the constitutively activated STAT3 signaling pathway in human esophageal squamous carcinoma cells, resulting in cell cycle arrest and proliferation inhibition.
