ObjectiveTo explore the best treatment method for patients with pancreatic cancer by analyzing the clinical and survival features.MethodsThe clinical data of 74 patients with pancreatic cancer diagnosed by pathology diagnosis(surgical pathology or biopsy) or clinical diagnosis(imaging + tumor marker CA19-9) were collected.The cases were divided into 5 groups according to different therapy methods:surgery alone group(11 cases),postoperative chemotherapy group(20 cases),palliative chemotherapy group ( 13 cases),palliative radiotherapy group ( 13 cases),untreated group ( 17 cases).The clinical features and overall survival time of patients with pancreatic cancer were analyzed.ResultsThe median overall survival time of postoperative chemotherapy group was longer than that of untreated group (300 d vs.119 d,P ＜ 0.01 ) ; The median overall survival time of surgery alone group,palliative chemotherapy and palliative radiotherapy group had no significant difference compared with that of untreated group (120,164,109 d vs.119 d,P＞ 0.05 ).The patients with advanced pancreatic cancer often suffered from abdominal pain,jaundice,nausea,vomiting,weight loss and other associated symptoms.The incidence of jaundice of patients undergoing surgery was lower compared with non-surgical patients,but the difference was not significant [ 19.35％ (6/31 ) vs.37.21％ (16/43),X2 =2.75,P =0.10 ].The incidence of abdominal pain of patients with radiotherapy was lower than that of non-radiotherapy patients[ 23.08％ (3/13) vs.68.85％(42/61 ),x2 =12.59,P =0.00 ].The ascites incidence rate was 75.68％ (56/74) which shortened the overall survival time,and untreated group had the highest risk rate of ascites.ConclusionsOperation combined with chemotherapy is a better treatment that can improve the overall survival time of patients with pancreatic cancer.Radiotherapy can obviously relieve the abdominal pain.Ascites is a signal of poor prognosis during the treatment process.

ObjectiveTo analyze the prevalence and epidemic trend of human brucellosis between 2007 -2010 in Qian'an county,and to provide a basis for future prevention and control measures. Methods Epidemiological data of brucellosis between 2007 - 2010 were obtained from the national disease surveillance report on management information system, population data were from the national disease surveillance information management system for basic information reporting system, and descriptive epidemiological methods was used for statistical analysis. Results A total of 86 cases were infected with brucellosis in Qian'an county from 2007 to 2010, with 68 cases of male and 18 cases of female, and male to female ratio was 3.78 : 1. Patients were mainly in the age of 20 - 55, with 40 - ＜ 45 year-old group the highest. All patients were local residents. Most professional were livestock acquisition, processing and aquaculture personnel. The majority of patients lived in Jianchang town,with 51 cases, accounting for 59.30％. Thirteen patients were reported in 2007, incidence was 0.0201‰(13/ 647 983). Thirty-nine patients were reported in 2010, and incidence was 0.0563‰(39/657 380). There was a fluctuations increase from 2007 to 2010. In 2007 brucellosis occurred in only two townships(towns), which spread to eight townships (towns) and urban areas in 2010. ConclusionsThe epidemic of human brucellosis in Qian'an is in a spreading trend. We recommend the government to strengthen the quarantine of livestock, and the infected livestock should be timely treated. Strengthen the prevention and control in Jianchangying. At the same time increase the brucellosis propaganda, and enhance self-protection awareness of the occupational groups.

OBJECTIVETo compare the efficacy of internal fixation (including PFNA and PFN) versus hip replacement (including FHR or THA) in the treatment of trochanteric fractures in adults.

METHODSReports of studies using randomized controlled trials (RCT) to compare internal fixationg with hip replacement in the management of intertrochanteric fractures were retrieved (up to January 1, 2013) from the Cochrane Library, PUBMED Data, CNKI (China National Knowledge infrastructure), Elsevier, the Chinese Biomedical Database, Wanfang Data, and manually. Methodological quality of the trials was critically assessed, and relevant data were extracted. Statistical software RevMan 5.0 was used for data-analysis.

RESULTSSeven articles were included in the meta-analysis. The results showed that,compared internal fixation with hip replacement,there were statistical significance in the duration of surgery time [WMD = -2.66, 95% CI (-5.25,-0.06), P = 0.05], intra-operative blood loss [WMD = -24.20, 95% CI (-30.38, -18.02), P < 0.000 01], hospital stays time [WMD = -4.72, 95% CI (-5.18, -4.25), P < 0.000 01], bearing load time [WMD = -29.54, 95% CI (-30.77, -28.31), P < 0.000 01], total complications rate [WMD = 0.15, 95% CI (0.11, 0.22), P < 0.000 01], the good rate of Harris scores [WMD = 1.09, 95% CI (0.54,1.32), P < 0.05]. However, there were no statistical significance in the rate of deep venous thrombosis [WMD = 1.09, 95% CI (0.47, 2.55), P > 0.05]. CON- CLUSION: Hip replacement (containing FHR or THA) for the treatment of intertrochanteric fractures is superior to internal fixa- tion in regards to the duration of surgery time, the mean duration of hosipital stays, mean post-operative down time, intra-opera- tive blood loss, the rate of post-operative good Harris scores. But there is not enough evidence to show any difference between hip replacement (containing THA or FHR) and internal fixation in regards to the rate of deep venous thrombosis. However, internal fixation for the treatment of intertrochanteric fractures is superior to hip replacement (containing FHR or THA) in regards to total complications rate.

To investigate the effect and possible mechanism of echinacoside-containing serum on the osteogenic differentiation in rat bone marrow mesenchymal stem cells. Rat bone marrow mesenchymal stem cells were cultivated by the whole bone marrow adherence method. The 3rd generation of cells were divided into 3 groups: the blank control group, the classic osteogenic-induced group and the 10% echinacoside-containing serum group. The expression of alkaline phosphatase and osteocalcin were detected by ELISA. The ex- pression of ZHX, protein was detected by Western blot technique. RT-PCR technique was used to detect the expression of ZHX₃mRNA. According to the result, the expressions of the alkaline phosphatase and osteocalcin in the classic osteogenic-induced group and the 10% echinacoside-containing serum group were significantly higher than that of the blank control group (P <0. 01). And expressions of the alkaline phosphatase activity and osteocalcin in the 10% echinacoside-containing serum group were significantly higher than that in the classic osteogenic-induced group (P < 0.01). Meanwhile, the classic osteogenic-induced group and the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the black control group, with significant differences (P < 0.01); the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the classic osteogenic-induced group, with a significant difference (P < 0.01). In conclusion, 10% echinacoside-containing serum can promote the differentiation of the bone marrow mesenchymal stem cells cultured in vitro. Its mechanism may be correlated with the increase in the ZHX₃expression.
