Objective:The present study discussed the clinical diagnosis and treatment of pancreatic body and tail carcinoma. Methods:The data of 52 patients with pancreatic body and tail carcinoma treated in Tianjin Medical University Cancer Institute and Hospital from January 2008 to December 2012 were reviewed retrospectively. The data included historical materials of perioperative examination and therapy. The data of 49 cases were reviewed retrospectively, and the median survival was calculated by the Kaplan-Meier method. The effects of the clinicopathologic parameters on the prognosis of patients with pancreatic body and tail carcinoma were examined by the log rank test. Results:Thirty-eight patients underwent exploratory surgery among which 24 had surgical resection, and the standard procedure was distal pancreatectomy plus splenectomy. The tumor staging was stage I in five patients (13.16%), stage II in nineteen patients (50%), stage III in five patients (13.16%), and stage IV in nine patients (23.67%). The median survival time was 18.0 ± 1.23 months for patients who received radical resection and 10.0 ± 2.71 months for patients who underwent nonspecific treatment or palliative therapy. The radical resection was associated with a longer survival period than the nonspecific treatment or palliative therapy (P<0.01). Conclusion:Early diagnosis is the key to achieving long-term survival. The radical resection plays an important role in improving the surgical treatment.

objective: To develop injectable tissue engineered bone through injection of osteoblasts/alginate composite in rabbits. Methods: Bone marrow cells isolated from iliac bone of New Zealand rabbits were cultured and induced to differentiate into osteoblasts.The osteoblasts were mixed with 25 g/L sodium alginate solution to generate osteoblasts/alginate composite with final cellular density of 5?10 6/ml. 0.17 g of sterilized CaSO 4 powder was then added to 2 ml osteoblasts/alginate. The mixture was injected into the dorsal subcutaneous tissue at left side of 6 New Zealand rabbits. The alginate composite without osteoblasts was injected into the right side as the control. 4 and 8 weeks after implantation, the bone formation was evaluated by means of gross, X ray and histological observation. Results: 4 weeks after implantation, cartilage formation was observed and 8 weeks after implantation,new mature bone was observed in the osteoblasts/alginate composites. No new bone formation was observed in all of the control specimens. Conclusion: Calcium alginate can be used as a carrier in injectable bone tissue engineering, and new bone can be created through injection of osteoblasts/alginate composites in immune animals.

Objective:To assesss the effectiveness of dapoxetine in the treatment of premature ejaculation.Methods:Both English and Chinese studies involving men with prematrue ejaculation who were treated with dapoxetine from the Cochrane Library,MEDLINE,EMBASE and CNKI,CBM,VIP between 1979 and 2009.were included in the randomized controlled trials(RCTs) and the data processed by RevMan.Results:Five RCTs involving 4433 patients were included in the Meta analysis,of which 3 were of grade A and 2 were of grade B according to the quality evaluation of methodology.Intravaginal ejaculatory latency time(IELT),patient-reported global impression of change(PGI),satisfaction with sexual intercourse(SWSI),perceived control over ejaculation(PCOE),personal distress related to ejaculation(PDRE) were used for assessment.Meta analysis based on included studies of patients having been treated with dapoxetine for 9-24 weeks showed that:(1) the difference of the patients' IELT between treatment group and control group was statistically significan [P

OBJECTIVE:To evaluate the effect of Stronger Neo-Mioniphagen C(SNMC)on liver function of the patients with hepatocarcinoma associated with cirrhosis.METHODS:55patients with hepatocarcinoma associated with cirrhosis were allocated to2groups randomly,group A:before operation SNMC(1ml/kg)was dripped intravenously to the patients,group B:before surgery NS(1ml/kg)was administered.On the1st、3rd、6th postoperative day,the index of liver function of the perive?nous blood were analyzed statistically.RESULTS:On the1st、3rd postoperative day,all the value of liver function in both group is higher than the basic,and the value in group A is lower than that in group B(P

The left ventricular apical systolic dysfunction syndrome was a rare acute cardiac syndrome.Its clinical presentation and electrocardiography were similar to acute myocardial infarction.The syndrome was characterized by transient ventricular wall-motion abnormalities involving the left ventricular apex and mid-ventricle in the absence of obstructive epicardial coronary disease.Cardiac enzyme was normal or minor elevation.At present,the cause of the syndrome is unknown.In this paper,we describe a 56-year-old female patient.She was admitted in hospital for acute appendititis and the transient left ventricular apical ballooning syndrome.She developed acute heart failure and septic shock in the hospital.The drainage of the appendiceal abscess was done and the heart failure and septic shock recovered completely in a few days.

Objective To explore the clinical characteristics,pathology,prognosis and proper treatment of tubular carcinoma of the breast. Methods The clinical data of 11 patients with tubular carcinoma of the breast treated in Peking Union Medical College Hospital were retrospectively analyzed.Results The incidence of tubular carcinoma of the breast account for 0.4% of the total breast cancer cases.Eight out of 11 cases had palpable painless lumps in the breast.Six cases received modified radical mastectomy,among which one patient received modified radical mastectomy of both sides.Four patients underwent breast conservation therapy.Sentinel lymph nodes biopsy was conducted in 2 patients.By immunohistochemistry ER was positive in 6 cases,PR was positive in 7 cases,2 cases were axiilary lymph node positive.Three patients received chemotherapy.Two patients received endocrine therapy(tamoxifen or aromatase inhibitor).Other patients received combined therapy including radiation,endocrine therapy and chemotherapy.All the patients have been followed up from 1 month to 7 years and within the period there is no recurrence,metastasis and death. Conclusion Tubulax carcinoma of the breast is a kind of low malignant tumor.Proper surgery and adjuvant therapy is important to improve survival and the quality of life.

Objective To identify significantly differentially expression of rat by genes chip,try to find out the initiating factors and molecular mechanisms that oxidative stress originate or strengthen the steriod-induced necrosis of femoral head(SINFH).Methods Twenty Wistar rats were dived into experimental group and control group randomly.The rats were injected intraperitoneally whith endotoxin,and then injected intramuscularly with high-dose methylprednisolone or saline in experimental group and control group respectively.The mRNA was extracted from the femoral head of rats inevery group,and the cDNA probes were obtained by inverse transcript,and then carried out microarray detection.The quantitative RT-PCR was used to confirm the results of the microarray.Results Histopathological findings revealed that the experimental group rats had femoral head necrosis,trabecular bone disorders,thinning,bone cell necrosis,and the rate of empty lacunae increased,and in control group no femoral head osteonecrosis was found.Total of 27 differentially expressed genes were found,and of which 4 genes(COX6A2,COX4I2,SOD3,and DUSP1)were significantly different.The expression of these 4 genes were down-regulated.The functions of these four genes involved in inhibition of reactive oxygen species(ROS)generation,accelerated removal of ROS and protection tissue from oxidative damage and so on.Conclusion The expression of oxidative stress-related genes in SINFH of rats exist change.COX6A2,COX4I2,SOD3,and DUSP1 are key genes in process of oxidative stress originate or strengthen the SINFH.
