Objective To observe the clinical efficacy of duloxetine in the treatment of malignant neuropathic pain with depression.Methods 60 patients were randomly divided into two groups as study group(30 cases) and contrdl group(30 cases) and treated for 4 weeks.The patients of study group were treated with duloxetine and oxycontin,and the patients of control group were treated with oxycontin only.Numberical rating scale (NRS) on pain,criteria of pain relief and Hamilton depression scale(HAMD,17 items) score were used to assess the therapeutic effect before and after treatment.Results By the end of the fourth week of treatment,the average usage of oxycontin of the study group was significantly less than control group((45.6±8.5) mg vs (88.2±5.2)mg,P＜0.05).The effective rate of pain relief in the study group was significantly higher than that in control group (93.3％ vs 73.3％,P＜0.05).Comparing pre-treatment,the score of HAMD of the study group had a remarkable decrease ((11.45±4.56) vs (23.07±5.47),P＜0.01).In comparison to the score of control group,study group had a significant effect ((11.45±4.56) vs (18.75±4.21),P＜0.01).Conclusion Duloxetine is one of effective agents in the treatment of malignant neuropathic pain with depression,which can alleviate depression and relieve pain.Duloxetine have mild adverse effects and good tolerance.

Objective To present and summarize the data concerning the treatment and prognosis of acute limb arterial embolism in West China Hospital.Methods Forty three patients with 52 limbs of acute arterial embolism were treated in West China Hospital from January 2003 to March 2006.There were 15 males and 28 females,aging from 26 years to 77 years 〔(58.88?13.90) years〕.The diagnosis was based on clinical manifestations and results of color Doppler sonography or DSA.The follow-up ranged from 1 month to 39 months.The following factors,which might influence the prognosis,were analysed through multiple linear regression of SPSS 10.0:age,sex,uper limb or lower limb,location of embolus,ischemic time,clinical categories of acute limb ischemia,history of smoking,atherosclerosis and other combined diseases,pervious history of acute limb arterial embolism,operative or nonoperative treatment,and postoperative complications.Results Clinical categories of acute limb ischemia include:Ⅰ(n=0),Ⅱa(n=16),Ⅱb(n=29),Ⅲ(n=7).The ischemic time varied from 3 h to 2 weeks.The sources of embolus:heart(n=39),vessle(n=7),iatrogenic origin(n=1),unidentidied origin(n=5).The therapies included embolectomy(n=38),catheter-directed thrombolysis(n=2) and medical treatment(n=12).The following postoperative complications occured:compartment syndrome(n=12),respiratory failure(n=3),alkalolsis(n=3),acute renal failure(n=2),wound infection(n=2) and pulmonary infection(n=1).Two patients died of cerebral infarction in hospital and one patient died of heart failure 3 months after discharge.Thirty-eight patients with 45 diseased limbs were followed up.The results were excellent in 13 limbs,good in 15 ones,fair in 8 ones and poor in 9 ones.The statistically significant influencing factors of prognosis include ischemic time,clinical categories of acute limb ischemia and history of smoking(P

BACKGROUND:Ligamentum flavum hypertrophy is one of the most important factors of lumbar spinal stenosis, but the molecular mechanism is stil not very clear. OBJECTIVE:To explore the role of basic fibroblast growth factor, connective tissue growth factor and transforming growth factor β1 in hypertrophy of the lumbar ligamentum flavum. METHODS: The ligamentum flavum samples were divided into three groups according to different diseases: control group (acquired from the patients with lumbar spinal canal tumor,n=6), lumbar disc herniation (LDH) group (acquired from the patients with LDH,n=6) and lumbar spinal stenosis (LSS) group (acquired from the patients with LSS,n=6). Then the mRNA expressions of basic fibroblast growth factor, connective tissue growth factor, transforming growth factor β1 and colagen I, III, V of the ligamentum flavum were detected using real-time quantitative RT-PCR method. The roles of basic fibroblast growth factor, connective tissue growth factor and transforming growth factor β1 were explored. RESULTS AND CONCLUSION:The expression of basic fibroblast growth factor mRNA in the LSS group was significantly higher than that in the LDH and control groups (bothP < 0.05); the expression of connective tissue growth factor mRNA was not found statisticaly different among the three groups, although it was slightly higher in the LSS group (P> 0.05); the expression of transforming growth factor β1 mRNA was significantly higher in the LSS group than in the LDH and control groups (bothP < 0.01). The colagen I mRNA expressed significantly higher in the LSS group than the LDH and control groups (bothP < 0.05), but both the colagen III and V mRNA showed no significant difference among the three groups (P> 0.05). This study indicate that both basic fibroblast growth factor and transforming growth factor β1 play important roles in the formation process of the lumbar ligamentum flavum hypertrophy, and the main type of the colagen in the hypertrophied ligamentum flavum is colagen I.

Objective To explore diagnosis and treatment of biliary hypoplasia with huge choledochal cyst in infants.Methods From Feb 2003 to Dec 2011,278 choledochal cyst cases were treated in our hospital.There were 3 infant cases of biliary hypoplasia with huge extrahepatic choledochal cyst diagnosed and treated during this period.All patients underwent cholangiogram demonstrating patent,but markedly diminutive extrahepatic biliary structures.After excision of the cyst,hepatic duct was injured in 1 case.The cyst wall was removed,a stent was put inside of hepatic duct,and Roux-en-Y hepaticojejunostomy was porformed.Results All three patients (ages from 1 month to two months) received the Roux-en-Y hepaticojejunostomy,none of our patients has developed stenosis and fistula of the Roux-en-Y hepaticojejunostomy.Intraoperative cholangiogram showed the huge choledochal cyst and diminutive intrahepatic ducts.All three cases were followed-up for 1-5 years,there was no jaundice and nor stones formation.Conclusions In cases of huge choledochal cyst when intraoperative cholangiogram demonstrates a diminutive biliary tree with huge choledochal cyst,great care is required during cyst excision in order not to injury the hepatic duct.Stent placement into hepatic duct helps bile flow at early stage after surgery.

Objective To compare the tumor sizes of primary lesions in pancreatic cancer based on CT scan and postoperative pathological analysis and measure the extent of filtration under a microscope,and to determine the CTV in radiotherapy target delineation.Methods A total of 19 patients with pancreatic cancer who were admitted to PLA General Hospital and Air Force General Hospital,PLA from 2013 to 2014 were analyzed.In 15 patients,the maximum diameters of tumor cross-section were measured based on the images of preoperative multi-slice spiral CT and postoperative gross samples,respectively.In 19 patients,the extent of tumor infiltration was measured on pathological sections under a microscope and the actual extent of infiltration was calculated.The paired t-test was applied to analyze the differences in the results of different measurement methods.Results In the 15 patients,the maximum tumor diameters measured with gross samples and CT scan were 33.6 mm and 30.1 mm,respectively (P=0.000),and the median and mean of the differences were 3.1 mm (1.2-8.0 mm) and 3.6±2.0 mm,respectively (95％ CI 1.2-6.0).In the 19 patients,the maximum actual infiltration distance and the maximum distance measured were 3.50 mm and 3.19 mm,respectively (P=0.000),and the median and mean of the differences were 0.31 mm (0.15-0.50 mm) and 0.30±0.09 mm,respectively.The maximum distance between the margin of primary lesions and the infiltrating lesions was 5.21 mm,with a median of 3.34 mm (2.19-5.21 mm) and a mean of 3.50± 0.88 mm (95％ CI 2.19-5.06).Conclusions Contrast-enhanced CT scan underestimates the actual size of primary lesions in pancreatic cancer,and an extension of 5 mm outside gross tumor volume (GTV) as CTV may not be sufficient.It is recommended to extend another 1-3 mm outside GTV as CTV.

We performed a simultaneous pancreas-kidney transplantation (SPK) for type 2 diabetes complicated with end-staged renal disease (ESRD) in March, 2007. The recipient was a 65-year old male, who suffered type 2 diabetes for 15 years and renal dysfunction for 5 years and other diabetic complications such as retinopathy and peripheral neuropathy. SPK was performed successfully for him, in which the kidney was placed in the left iliac fossa, while the pancreas in the right iliac fossa, with an entedc drainage for pancreas exocrine and a systemic drainage for endocrine. Serum C-peptide, creatinine and blood urea nitrogen reached normal levels on day 1,4 and 11 post-transplant, respectively. Blood glucose became stabilized gradually to normal level and therefore the injected insulin was stopped on day 16 post-transplant. Oral glucose tolerance test (OGTT) showed the function of grafted pancreas was normal after 3 weeks of transplant, and no transplant-related complications occurred. With the recipient followed up for 20 months, both his blood glucose level and renal function maintained normal without using insulin.

Objective: To explorer factors related to spontaneous reduction in twin pregnancy following assisted reproductive technology. Methods: 2 848 twin pregnant women with treatment of vitro fertilization-embryo transfer (IVF-ET) or intra cytoplasmic sperm injection (ICSI) cycles were enrolled at Assisted Reproductive Centre of the First Affiliated Hospital of Nanjing Medical University, Nanjing Maternity Hospital and Shengjing Hospital of China Medical University from January 2013 to December 2016 respectively. Basic features of subjects, relevant clinical indicators, factors of assisted reproductive therapy and pregnancy outcome were collected from clinical assisted reproductive technology management system. According to the pregnancy outcome, the subjects with spontaneous reduction were classified as case group (n=686), and those with normal twin birth were classified as control group (n=2 162). The features of subjects in the two groups were compared. Non-conditional logistics regression model was used to analyze the related factors of the occurrence of spontaneous reduction. Results: The age of case group and control group were (30.6±4.3) and (30.2±4.0) years old respectively. After the adjustment of male sterile factor, compared to the subjects with luteinizing hormone level on the day of human chorionic gonadotropin administration (HCG) <1.43 IU/L, OR (95%CI) of the subjects with value at 2.59-5.10 IU/L was1.62 (1.08-2.42).Compared to the subjects with number of transferred embryo as 1, OR (95%CI) of the subjects with value as 3 was 0.23 (0.07-0.74). Compared to the subjects with stage of transferred embryo as cleavage stage, OR (95%CI) of the subjects with blastula stage was 0.42 (0.27-0.67). Conclusion Luteinizing hormone level on day of HCG, number and stage of embryo transfer are related factors to spontaneous reduction in twin pregnancy following assisted reproductive technology.

In this study, we used next-generation sequencing methods to screen 300 individuals for BRCA1 and BRCA2. A novel mutation (c.849dupT) in BRCA2 was identified in a female patient and her unaffected brothers. This mutation leads to the truncation of BRCA2 functional domains. Moreover, BRCA2 mRNA expression levels in mutation carriers are significantly reduced compared to noncarriers. Immunofluorescence and western blot assays showed that this mutation resulted in reduced BRCA2 protein expression. Thus, we identified a novel mutation that damaged the function and expression of BRCA2 in a family with breast cancer history. The pedigree analysis suggested that this mutation is strongly associated with familial breast cancer. Genetic counsellors suggest that mutation carriers in this family undergo routine screening for breast cancer, as well as other malignancies, such as prostate and ovarian cancer. The effects of this BRCA2 mutation on drug resistance should be taken into consideration during treatment.

OBJECTIVETo assess the prevalence of colorectal cancer (CRC) in Beijing and the reliability of the sequential fecal occult blood test (SFOBT) for CRC screening.

METHODSOf the natural population (48 100 persons) in several Beijing communities, we screened 26 827 persons with age over 30 using the SFOBT screening program, Guaiacum Fecal Occult Blood Test (GFOBT), Immuno Fecal Occult Blood Test (IFOBT), and colonoscopies.

RESULTSThe screening rate of the population was 74%. The positive rate of SFOBT was 5.6%. The prevalence of CRC in the entire population of Beijing was therefore calculated to be 36.57/10(5). Of 12 CRC detected patients, 4 cases were in stage Dukes A (33.33%), 7 cases in stage Dukes B (58.33%), only 1 case (8.34%) in stage Dukes C.

CONCLUSIONSThe prevalence of CRC in Beijing is one of the highest in China. Individuals at high risk for CRC or those over 50 years of age should be considered as primary candidates for screening. SFOBT screening is a cost-effective and reliable method for early detection of CRC.
