Objective Analysis of clinical features and treatment of nasal type NK/T cell lymphoma, to improve the understanding of this special type of lymphoma.Method The clinical data of 34 patients with nasal type NK/T cell lymphoma confirmed by pathology were retrospectively analyzed.Result In 31 cases, 26 cases were EB virus (EBV) infection positive, recent Treatment Effectiveness in the positive group was significantly lower than the negative group (38.46%vs. 87.50%;P<0.05) . Follow up showed until October 2015, 19 of 34 patients died. Among them, 17 cases died of disease relapse or progression, 2 cases died of other diseases. 15 patients survived (11 of them were disease-free) and the median overall survival time was 37 months. The 2 year overall survival was related to clinical stage, B symptoms, EBV infection (the P values were 0.017/0.001, 0.005, and 0.039 respectively).Conclusion EBV infection is associated with patient's treatment response in NK/T-Cell Lymphoma; and the prognosis is associated with clinical features such as clinical stage, B symptom, and EBV infection.

OBJECTIVETo compare clinical efficacy of anatomic locking plate and Gamma nail in treating unstable femoral intertrochanteric fractures with external wall fractures.

METHODSFrom June 2010 to June 2014,clinical data of 44 patients with intertroehanteric fractures associated with lateral wall fractures (type 31A2.2-3.3) followed more than 12 months,which treated with Gamma nail or anatomic locking plate,were retrospective analyzed. Sixteen patients were treated with anatomic locking plate, including 6 males and 10 females aged from 32 to 83 years old with an average of 56.5 years old. Twenty-eight patients were treated with Gamma nail including 17 males and 11 females aged from 26 to 87 years old with an average of 60.4 years old. Operative time, intraoperative fluoroscopy times, blood loss (intraoperative and hidden blood loss), hospital stays were observed and compared. PPMS and HHS scoring were used to evaluate postoperative clinical effect.

RESULTSAll patients were followed up from 12 to 24 months with an average of 16.2 months. Operative time in Gamma nail was shorter than anatomic locking plate; while blood loss( intraoperative and hidden blood loss) and intraoperative fluoroscopy times in anatomic locking plate were less than that of in Gamma nail. There was no significant meaning in hospital stays between two groups. Postoperative full weight-bearing time in anatomic locking plate was prolonged than Gamma nail. At the final following-up, PPMS in Gamma nail was 7.50 ± 1.78 and 6.82 ± 1.38 in anatomic locking plate, and there was no obvious meaning between two groups (t = 2.341, P = 0.132); there was no significant differences in HHS score between Gamma nail (83.25 ± 11.18) and anatomic locking plate (86.14 ± 12.36) (t = 1.923, P = 0.243). The incidence of complications in Gamma nail was less than anatomic lock-ing plate (P = 0.005).

CONCLUSIONAnatomic locking plate for intertrochanteric fractures with external wall fractures could avoid re-injury of external wall, especially for severe comminuted fractures, difficult for intramedullary nailing, and there was no significant meaning in hip joint function compared with Gamma nail, while postoperative incidence of complications was higher than Gamma nail, so early weight-bearing was not stress.

Objective To investigate the change in antimicrobial susceptibility of Enterococcus faecalis (E.faecalis) and Enterococcus faecium (E.faecium) isolated from clinical urine specimens, so as to provide laboratory evidence for clinical anti-infective treatment.Methods Antimicrobial susceptibility of E.faecalis and E.faecium isolated from urine specimens from 20 tertiary hosptials in China between 2004 and 2014 were analyzed, drug-resistant genes of vancomycin-resistant Enterococcus(VRE)were detected with polymerase chain reaction (PCR).Results A total of 788 Enterococcus strains were isolated in 2004-2014, 371 strains were E.faecalis strains, 417 were E.faecium strains.Susceptibility rates of E.faecalis to ampicillin, nitrofurantoin, fosfomycin, vancomycin, and teicoplanin were all>90%, susceptibility rates to rifampin, minocycline, and erythromycin were all<20%, there was significant difference in the susceptibility rate of E.faecalis to fosfomycin betwen July 2011-June 2012 and July 2009-June 2010(P<0.0167).Susceptibility rates of E.faecium to vancomycin and teicoplanin were 96.9% and 97.4% respectively, susceptibility rates to nitrofurantoin, minocycline, and fosfomycin were 41.7%, 51.8%, and 78.2% respectively, susceptibility rates to ampicillin, levofloxacin, rifampicin, and erythromycin were all<10%;susceptibility rates of E.faecium to nitrofurantoin had decreased tendency in different years (any two group comparison, all P<0.0167), susceptibility rates to fosfomycin in July 2011-June 2012 and July 2013-June 2014 both decreased compared with July 2009-June 2010(both P<0.0167),there were no significant changes in antimicrobial usceptibility rates in different years.14 strains of VRE all carried vanA resistance gene.Conclusion E.faecalis strains isolated from urine are susceptible to ampicillin, nitrofurantoin, and fosfomycin, E.faecium are not susceptible to most antimicrobial agents;E.faecalis and E.faecium are both susceptible to vancomycin and teicoplanin, only a few strains are resistant to antimicrobial agents.

Objective To evaluate the clinical effectiveness of perioperative fast-track surgery(FTS)program and nutrition support in the elderly patients with gastric cancer.Methods Totally 42 patients were equally randomized into FTS group(receiving perioperative FTS program)and control group(receiving a conventional therapy).The postoperative first defecation time,postoperative hospital stay,hospitahzation expenditure,and postoperative complications were compared between these two groups.Results The postoperative first defecation time and postoperative hospital stay were(75.4±24.3)hours and(11.2±3.2)days in FIS group and(98.0±22.6)hours and(14.4±4.6)days in control group(P=0.0165,P=0.0004;respectively).The hospitalization expenditure was significantly lower in FTS group than in control group[(3.66±0.48)×104 vs.(4.56±0.78)×104 RMB yuan;P=0.0001].The incidence of postoperative complications in FTS group was also significantly lower than that in control group(9.5% vs.28.6%,P=0.0422).Conclusion Perioperative FTS program can accelerate postoperative rehabilitation,shorten hospital stay,lower hospitalization expenditure,and reduce the incidence of postoperative complications.

Objective To summarize the treatment experiences in gastrointestinal leaJcage atter gastrectomy for gastric cancer. Mehods From January 1997 to December 2006 the clinical data of 37 cases of gastrointestinal leakage including anastomotic leakage in 19 cases and duodenal stump leakage in 18 after gastrectomy for gastric cancer in People's Liberation Army General Hospital were analyzed retrospectively. Results All of the Cases were treated with abdominal drainage,continuous gastrointinal decomnression and parenteral nutrition combined with enteral nutrition.There were 32 cases receiving glutamine enrichment nutrition support,31 ases used somatostatin,13 cases received supplemented recombinarlt human growth hormone.Fistula healed in 21～30 d in 9 cases after gastrectomy,in the other 24 cases fistula healed in 30-60 d,while it healed in 60～81 d in the remaining 2 cases.Two died of leakage associated complications after gastrectomy for gastric cancer including anastomotlc leakage follwing esophagojejunostomy complicated by severe thoracic and lung infection in one and duodenal stump leakage complicated by severe abdominal cavity sepsis and hemorrhage in the other. Conclusion Patent and effective abdominal cavity drainage,continuous gastrointestinal decompression,parenteral nutrition combined with enteral nutrition,glutarnine,somatostafin and recombinant human growth hormone are the'mportant factors for the healing of gastrointestinal leakage after gastrectomy tor gastric cancer.

Objective To investigate the imaging diagnosis and surgical treatment of intestinal malrotation in adult patients. Methods The clinical data of 11 adult patients with intestinal malrotation who had been admitted to General Hospital of PLA from January 2003 to December 2007 were retrospectively analyzed. Multiple imaging modalities, including barium enema, gastrointestinal radiography, B sonography, computed tomography (CT) scan and mesenteric angiography were applied for diagnosis. All patients received Ladd procedure. Results Two patients were diagnosed by gastrointestinal radiography +B sonography, 4 by gastrointestinal radiography +CT scan, 1 by angiography, 1 by B sonography + CT scan, 1 by iodine radiography + CT scan and 2 by intraopera-tive examination. After the operation, 2 had renal insufficiency, 1 had intestinal fistula and 1 had short bowel syndrome and died at the third month after operation. Conclusion Combined application of multiple imaging modalities can improve the diagnostic rate, and Ladd procedure is effective and safe for adult patients with intes-tinal malrotation.

Background and purpose: With the increase of aging population, elderly patients (age ≥70 years) with esophageal squamous cell carcinoma occurred more and more. However, few studies have focused on elderly esophageal squamous cell carcinoma patients. This study aimed to assess the outcomes and prognostic factors for elderly patients with esophageal squamous cell carcinoma treated after deifnitive chemoradiotherapy. Methods:We retrospectively analyzed 53 patients (age≥70 years) with esophageal squamous cell carcinoma and treated with deifnitive radiotherapy with or without chemotherapy from Fudan University Shanghai Cancer Center from Mar. 2009 to Dec. 2011. Results:Median age was 74 years. Twenty-nine patients underwent radiotherapy, 24 patients underwent radiochemotherapy. 1-, 2-, 3-, and 5- year survival was 62%, 44%, 33% and 19% respectively. Grade 2 and above acute radiation-induced esophageal toxicity and radiation pneumonitis occur rate was 6% and 9% respectively. No treatment-related deaths occurred and no patients experienced any grade 4 and above toxicities. Multivariate analysis identiifed treatment modality, tumor site and smoking history as independent prognostic factors for overall survival. Conclusion:Radiotherapy may be an acceptable treatment option for elderly patients with esophageal squamous cell carcinoma. In appropriately selected patients, concurrent chemotherapy could bring a better overall survival.

Objective To analyze the genotype distribution of human papillomavirus( HPV) strains and their epidemiological characteristics in cervixes of Chinese females. Methods Pertinent litera-tures published during 2004 to 2013 were screened from PubMed,China National Knowledge Infrastructure (CNKI)and Wanfang database for data analysis. Results There were 245 studies screened out for the me-ta-analysis. A total of 661 658 cases met the inclusion criteria,ranging from 16 to 87 years old. All prov-inces and territories of China were covered by the data. The overall rate of HPV infection in cervix was 25. 0% among Chinese females. The predominant high risk genotype of human papillomavirus strains was HPV16,followed by HPV52,HPV58,HPV18,HPV33 and HPV31. HPV52 and HPV58 genotypes were more prevalent than HPV18 genotype. HPV35 and HPV45 genotypes were less popular. Conclusion The study suggested that the HPV infection showed obvious regional differences in genotypes. The genotype dis-tribution of HPV infection in China was different from that in other regions of the world. There were differ-ences with genotype distribution of HPV strains among seven geographic regions of China.

Objective To explore the effect of preservation of inclined fractured permanent molars by transverse fixation with screw post,and provide a practical method for reserving the inclined fractured permanent molars.Methods Clinical data of 50 patients with inclined fractured permanent molars by transverse fixation with screw post in the Department of Stomatology of Tianjin First Central Hospital between January 2010 to December 2011 were reviewed retrospectively.After fixing the crown with steel-wire binding and root canal treatment,the molars were drilled a hole buccolingually and placed screw post.The flowable light-curing composite resin was used to seal the crack and bond screw post to prevent the relative movement.All treated molars were restored with full crown.All patients were followed up for 10-60 months.The therapeutic effects were observed.Results After 5 year-follow-up,41 cases were cured completely,6 cases were cured clinically,and 3 cases failed treatment.Conclusion The transverse fixation with screw post and bonding technique can preserve the inclined fractured molars to gain chewing function and avoid or reduce the extraction of affected teeth,which provides a better restoration effect.
