Anastomotic leakage is one of the most serious complications following colorectal surgery. Occurrence of anastomotic leakage is concealed and numerous risk factors might relate to anastomotic leakage, which greatly affect the postoperative outcomes and life quality of patients. Therefore, it is necessary to recognize risk factors to predict anastomotic leakage in advance and adopt available treatments to reduce the incidence. This review summarized the risk factors of postoperative anastomotic leakage base on two aspects, and so on. Perioperative related factors and biological markers, aiming to provide a theory for predicting anastomotic leakage then improving the treatment outcomes of colorectal cancer patients .

Gut microbiota plays an important role in the development of colorectal cancer, such as Fusobacterium Nucleatum, Peptostreptococcus and Streptococcus thermophilus. At present, Surgery is the mainly treatment strategy of colorectal cancer patients, supplemented by postoperative radiotherapy and chemotherapy. The influence of gut microbiota on colorectal cancer is not limited to the tumor itself. After tumor resection, gut microbiota is still in a state of disorder, which will affect the short-term and long-term prognosis of patients. Therefore, understanding the relationship between gut microbiota and prognosis of colorectal cancer is helpful to improve the prognosis of patients and reduce postoperative complications. In this review, the author will summarize the influence of gut microbiota on short-term and long-term prognosis of colorectal cancer patients.

Objective To evaluate the diagnostic value of endoscopic ultrasonography (EUS ) combined with detection of immunoglobulin (Ig ) and T‐cell receptor (TCR ) gene rearrangements in primary gastrointestinal lymphoma (PGIL) .Methods From 12nd January ,2012 to 23rd May ,2014 ,the clinical data of 24 patients with suspicious PGIL under endoscopy (regular biopsy negative and without treatment) and underwent further EUS examination was retrospectively analyzed .All patients received EUS‐guided biopsy or EUS‐guided fine needle aspiration (FNA) and the tissue specimens were detected for Ig and TCR gene rearrangements .Considering biopsy result ,surgical pathological diagnosis and follow‐up result as gold standard ,the clinical significance of sensitivity ,specificity ,positive predictive value (PPV) , negative predictive value (NPV ) and accuracy of EUS combined with Ig /TCR gene rearrangements in PGIL were explored .Results Among 24 patients ,19 patients were finally diagnosed as PGIL ,which were all non‐Hodgkin′s lymphoma (NHL ) ;monoclonal gene rearrangement was found in 13 cases of the 19 cases .The left five cases were not lymphoma lesions (three cases of gastritis ,one case of leather stomach and one case of malignant melanoma) with no monoclonal gene rearrangement .In cases diagnosed as PGIL , 14 were B cell NHL ,which included eight cases of muscosa‐associated lymphoid tissue (MALT) lymphoma and six cases of diffuse large B cell lymphoma .Of which ,immunoglobulin heavy chain (IgH)/immunoglobulin kappa (IgK) gene rearrangement was found in 11 cases .A total of five cases were T cell NHL including one case of anaplastic large cell lymphoma , one case of NK /T cell lymphoma and three cases of enteropathy‐associated T‐cell lymphomas . TCR gene rearrangement was found in two cases .Because theoretically ,there was no gene rearrangement in natural killer (NK )/T cell lymphoma ,so NK /T cell lymphoma was excluded from statistical analysis .The sensitivity ,specificity ,PPV ,NPV and accuracy of EUS combined with Ig /TCR gene rearrangements detection in PGIL were 72 .2% ,100 .0% ,100 .0% , 50 .0% and 78 .3% ,respectively .Conclusion The detection of monoclonal gene rearrangement in tissues from EUS‐guided biopsy or EUS‐guided FNA had better diagnostic value in PGIL ,which improved the objectivity and accuracy of lymphoma diagnosis .

Objective To evaluate the relationship between neoadjuvant chemotherapy (combination of taxanes and anthracyclines ) induced-neutropenia and the efficacy of neoadjuvant chemotherapy and long-term survival in operable breast cancer patients. Methods Two hundred and eleven patients received 4 cycles of neoadjuvant chemotherapy (combination of taxanes and anthracyclines).Clinicopathological characteristics were compared between patients with neoadjuvant chemotherapy-induced neutropenia and patients without neutropenia. The efficacy of neoadjuvant chemotheray and long-term survival rate were analyzed. Results Among 211 patients there were 51 (24. 2% ) cases suffering from neutropenia and 160 (75.8%) cases were of no-neutropenia. The response to chemotherapy in patients with neutropenia were more effective than in no- neutropenia ones ( P ＜ 0. 05 ). The 5-year disease-free survival (DFS) in patients with neutropenia was 82. 4%, while the 5-year disease-free survival ( DFS) with nonneutropenia was 60% ( P ＜ 0. 01 ). Additionally, the 5-year overall survival ( OS ) in patients with neutropenia was 90. 2% and in patients with non-neutropenia patients was 67. 5% ( P ＜ 0. 01 ).Conclusions Chemotherapy-induced neutropenia during neoadjuvant chemotherapy combination of taxanes and anthracyclines in patients with operable breast cancer has a better prognosis. The sensitivity of tumors given to chemotherapeutic drugs could be evaluated by chemotherapy-induced neutropenia.

This study was aimed to distinguish Leonurus japonicus samples produced from different regions and growth environments in Sichuan by electronic nose. The sensor response value of odors of Leonurus japonicus sam-ples were obtained through electronic nose. Principal component analysis (PCA) and discriminant factor analysis (DFA) were used to combine the optimum feature parameters. The results showed that the PCA distinguish index was 82, and the DFA comprehensive classification rate was 97.96% among samples from different regions. The PCA distin-guish index was 84, and the DFA comprehensive classification rate was 100% among samples from different growth environments. The distinguishment and differentiation were effective. It was concluded that electronic nose can be ap-plied to identify the origin and growth environment of Leonurus japonicus from Sichuan to provided reference for odor differentiation.

Objective To analyze the epidemiological features and trends of glenoid fractures from 2003 through 2012 in the Third Affiliated Hospital to Hebei Medical University.Methods The clinical data were collected of the patients with glenoid fracture who had been treated between January 2003 and December 2012 in our hospital.The patients' gender,age and fracture type of Ideberg classification were documented.The data from January 2003 to December 2007 were assigned into group A and those from January 2008 to December 2012 into group B.The 2 groups were compared to find out the general epidemiological characteristics and trends in the recent 10 years.Results A total of 225 patients with glenoid fracture were collected,including 176 males and 49 females.The total male/female ratio was 3.59∶ 1.The glenoid fractures predominated in an age range of 31 to 40 years (23.56％).According to Ideberg classification,there were 35 cases (15.56％) of type Ⅰ,58 ones (25.78％) of type Ⅱ,64 ones (28.44％) of type Ⅲ,21 ones (9.33％) of type Ⅳ,30 ones(13.33％) of type Ⅴ and 17 ones(7.56％) of type Ⅵ.The male/female ratio was 5.29∶1 in group A of 107 patients and 2.69∶1 in group B of 118 patients.The mean age of group A was 40.2 ± 16.0 years and that of group B 47.5 ± 14.8 years.The differences in male/female ratio,mean age and distribution of age were statistically significant between the 2 groups (P ＜ O.05).The fractures predominated in an age range of 31 to 40 years (28.97％) in group A and in the age group of 51 to 60 years (27.12％) in group B.The most frequent fracture type was type Ⅲ in both groups,accounting for 29.91％ and 27.12％ respectively.There was no significant difference between the 2 groups in distribution of Ideberg classification (P ＞ 0.05).Conclusions The peak age of glenoid fractures was from 31 to 40 years.There was an increasing trend in the mean age.There were more male patients than female ones.The high-frequency type was Ideberg type Ⅲ.

With the development and application of microarray and high-throughput sequencing technology, it is possible to genomi-cally scan breast cancer associated CNV and SNPs. Multiple researches showed that the frequent aberrance of 8q24 was associated with breast cancer. Oncogenes such as MYC, PSCA and breast cancer associated loci are located in 8q24, and frequent amplification of 8q24 was proposed to be related with breast cancer development and prognosis. This review summarizes the association of the 8q24 amplification and SNPs with breast cancer by correlated genes on this locus.

Objective To analyze the effect of haploidentical hematopoietic stem cell transplantation (HID-HSCT) on high-risk acute lymphoblastic leukemia (ALL),and to explore the influence of minimal residual disease (MRD) before transplant on the outcomes.Methods A retrospective analysis was performed on 39 high risk ALL patients receiving HID-HSCT in our hospital from Jan.2013 to Jan.2018.The clinical features,stem cell engraftment,complications,survival and recurrence were compared between patients with pretransplant MRD + and MRD-.Results All the 39 patients presented with successful engraftment.The overall survival (OS) was 54.67％;the disease free survival (DFS) was 40.96％;the incidence rate of acute graft versus host disease (aGVHD) was 53.8％,including 23.1％ Ⅱ-Ⅳ degree aGVHD and 2.6％ Ⅲ-Ⅳ degree aGVHD.There was no significant difference in stem cell engraftment,GVHD,cytomegalovirus infection and hemorrhagic cystitis between MRD + and MRD-patients.DFS and OS in MRD + patients were significantly lower than those in MRD-patients;the cumulative RR rate increased significantly,and there was no significant difference in cumulative TRM.Conclusion HID-HSCT was an effective method to treat high-risk ALL,but MRD + patients had high recurrence rate and poor prognosis.Strategy adjustment should be considered to reduce tumor residual and the transplantation strategy should be optimized for these kinds of high risk patients,so as to improve long-term outcomes.

Objective To study the diagnostic value of endoscopic ultrasound guided fine needle aspiration (EUS-FNA) combined with the new category of papanicolaou society of cytopathology in solid pancreatic lesions (SPL) rapid on-site evaluation (ROSE).Methods From February 2011 to October 2014,225 patients with SPL who underwent EUS-FNA and obtained the cytological diagnosis were enrolled.The lesions were finally diagnosed according to pathological results,imaging and follow-up data,and then the sensitivity,specificity,and accuracy of EUS-FNA in the diagnosis of SPL were calculated based on the new papanicolaou society of cytopathology terminology.Logistic stepwise regression analysis was performed to analyze the risk factors.Results Among 225 patients with SPL,96 cases (42.7％)had uncertain cytological diagnosis,17.3％ (39/225) could not be diagnosed,8.0％ (18/225) were atypical lesions,and 17.3％ (39/225) were suspicious malignant carcinomas.Among 129 cases (57.3％)with certain cytological diagnosis,15.1％ (34/225) were benign lesions,14.7％ (33/225) were tumors (benign or others) and 27.6％ (62/225) were malignant tumors.When atypical lesions were added into non-tumor lesions or tumor lesions,the sensitivity,specificity and accuracy of diagnosis were 87.3 ％,91.7％,88.2％,and 94.7％,72.2％,90.3％,respectively.Serum CA125≥14 kU/L (odds ratio (OR) =7.13,95％ confidence interval (CI) 2.02 to 25.22,P=0.002) and history of biliary disease (OR=3.85,95％CI 1.22 to 12.51,P=0.022) were two independent risk factors of pancreatic tumors.Conclusions Despite of a high percentage of uncertain cytological diagnosis,EUS-FNA still has high diagnostic value in SPL when combined with the new papanicolaou society of cytopathology terminology.Furthermore,serum CA125≥14 kU/L and history of biliary disease may help to diagnose pancreatic tumors.
