Objective To introduce the standard procedure of Cattell Braasch maneuver and evaluate the complication and clinical value of this maneuver as a important exploration method in the surgery of pancreatic tumors. Method The clinical data of 13 cases of pancreatic tumors explored by Cattell Braanch maneuver before undergoing tumor resection were analyzed. Results Among these 13 cases there were 6 cases of tumors of the head (the pancreatic adeuocarcinoma in 4 cases, solid pseudo-papillary tumor and endocrine tumor in one each cases) and 7 cases of tumor of the body and tail of the pancreas (adenocarcinoma in 4 cases, solid pseudo-papillary tumor in 1 case, endocrine tumor in 2 cases) Pancreaticoduodenectomy was performed in 6 cases, including segmental resection of the tumor invading the superior mesenteric vein( SMV )with length varying from 3 to 7 cm and direct end-to-end reanastomosis in 3 cases. Distal pancreatectomy plus spleuectomy was performed in the other 7 cases, including the case in which extended tumor resection demanded left nephrectomy. Operations lasted from 2. 5 hrs to 11 hrs, in which only 10 ～ 15 mins were needed for Cattell Braasch maneuver . The blood lose was from 300 ml to 1000 ml. There were neither mortality nor severe complications in these series. Conclusion Cattell Braasch maneuver facilitates the exploration and tumor resection in patients suffering from pancreatic neoplasms especially malignances with better view of the operation field,it helps to avoid incidental iatrogenic injury, and also to the nongraft PV/SMV end-to-end anastomosis after the resection of tumor invaded segment.

Objective To explore the feasibility of a novel incisionless laparoscopic technique in the treatment of colorectal tumor, and evaluate the preliminary clinical result of this technique. Methods The clinical data of 12 consecutive resected specimens of high located rectal or sigmoid tumor removed by traditional laparoscopic surgery were analyzed to probe the indication of this technique and the first 2 cases received incisionless laparoscopic anterior resection. Postoperative follow up was made to evaluate the clinical feasibilities. Results Among 12 explanted fresh specimens there were 1 adenoma and 3 adenocarcinoma cases in which the key steps of the new technique were successfully demonstrated. In two cases, the bowel above the tumor was cut and the distal end was inverted and pulled through the anus laparoscopically, the tumor along with the bowel resected, the stump pushed hack, and intralumen sigmoidproctostomy fashioned. In these two patients, one of sigmoid cancer and one of large rectal adenoma with focal canceration, the mean operation time was 200 min, mean blood lose was 50 ml, mean bowel function recovery time was 1.5 days. After 13 and 15 respective months fullow up there was no complications nor tumor recurrence. Conclusions Ineisionless laparoscopic surgery, while in line with tumor free principles, has the advantage of safety, cost-effectiveness and being cosmetic in selected cases.

Objective To identify the effect of specialized language training on the speech rehabilitation of total laryngectomy (TL)patients.Methods Twenty-seven TL patients were trained for esophageal speech by specialized speech-language pathologists from October 2005 to December 2006.Then the participants were followed and evaluated their esophageal speech level after one cycle of training program,1 month,3 months,6 months and 12 months after training program.Results The score of participants' esophageal speech was steadily improved during the 12 months after participating the training program.The score of esophageal speech greatly increased in the third month,and this significant improvement was kept until 12 months after the training program.The esophageal speech quality was negatively correlated with age and surgery area of patients.Conclusions Specialized speech-language training showed positive effect on esophageal speech rehabilitation,and esophageal speech training by specialists is worthy of wide application.

Objective To explore the hospitalization status of patients with chronic obstructive pulmonary disease ( COPD ) . Method In total, 12,838 COPD patients hospitalized from January 2008 to December 2014 were involved in the study and their hospitalization status were analyzed. Results Among the 12,838 patients, 2,499 were hospitalized for critical conditions (19.47%), 5,455 for acute attack (42.49%), 4,884 for acute exacerbation (38.04%). The ratio of male/female was 5.32:1. Those in 71 to 80 years old were at the highest risk. They were hospitalized at least for 1 time, at most for over 38 times, averaged (3.52 ± 4.05) times. Conclusions The COPD patients were hospitalized due to acute attack and acute exacerbation. The patients'age ranged from 71 to 80 years. The male patients had a predominant incidence than the female ones. The times of hospitalization were related with possible complications of other chronic diseases. Therefore, nursing staff should draw up individual continuing nursing strategies based on the patients′ hospitalization reasons to reduce the hospitalization rate of acute attack and acute exacerbation. Meanwhile, we should formulate the pre-hospital rescue plan for the hospitalized patients at the peak age and implement prospective nursing.

ObjectiveTo explore the relationship among 25-hydroxyvitamin D,serum calcium,calcium-sensing receptor,and breast cancer. Methods The expressions of calcium-sensing receptor (CaSR) in primary breast cancer,breast benign tumors,and normal breast tissue beside tumors were determined by immunohistochemistry S-P method as well as the concentration of serum 25 (OH) D and serum calcium in breast cancer and breast benign tumors by Enzyme-linked immunosorbent assay (ELISA),Tribromoarsenazo Ⅲ method.ResultsSerum 25 (OH) D level of breast cancer was significantly lower than the breast benign tumors [ (34.13 ± 14.14) nmol/L vs (50.29 ± 25.65 ) nmol/L,t =2.870,P =0.001 ].Serum level of 25 ( OH ) D in lymph node metastasis positive patient was lower than that in negative group [ (30.8 ± 9.71 ) nmol/L vs (43.7 ± 23.59) nmol/L,t =2.467,P =0.021 ].The positive expression of CaSR in breast cancer(88.9％ )was higher than breast benign tumors(60％,x2 =6.717,P ＜ 0.01 ) and normal breast tissue beside tumors (60％,x2 =5.628,P ＜ 0.05 ).ConclusionsConcentration of serum 25 (OH)D and expression of calcium-sensing receptor in the tissues may be associated with occurrence,development and prognosis of breast cancer.

In plants, UDP-L-rhamnose is one of the major components of cell wall skeleton. Rhamnose synthase plays a key role in rhamnose synthesis which converts UDP-D-glucose into UDP-L-rhamnose in plants. In this study, we isolated the 1058 bp promoter region of the rhamnose synthase gene AtRHM1 from Arabidopsis genome by PCR, and created a series of deletions of AtRHM1 promoter ranging from -931 bp to +127 bp. The full length of the promoter and its deletion derivatives fused with GUS reporter gene were introduced into wild-type Arabidopsis by Agrobacterium-mediated transformation respectively. The GUS staining and GUS enzymatic activity assay showed that the expression of AtRHM1 is induced at transcriptional level by glucose and the regulatory elements involved in the glucose response are located in the region of -931 bp - -752 bp which contains three G-box motifs.

BACKGROUNDThe management of Barcelona Clinic Liver Cancer (BCLC) stage B hepatocellular carcinoma (HCC) is controversial due to the early recurrence after curative hepatectomy, and many variables were related to the prognosis. The purpose of this study was to predict the tumor recurrence in early postoperative period of the patients with BCLC stage B HCC.

METHODSFrom January 2004 to January 2012, 104 patients with BCLC stage B HCC underwent hepatectomy. Clinicopathological factors and follow-up data were statistically analyzed to establish a predicting scoring system.

RESULTSThe overall survival rates for one, three, and five years were 69.2%, 52.7%, and 42.3%, and the disease-free survival rates for one, three, and five years were 52.9%, 47.3%, and 37.5%, respectively. The multiple factors analysis showed that the micro-vessel invasion, lymph nodes metastasis, multiple lesions, and the high expression of HMGB1 were independent factors (P < 0.05). A scoring system was established to predict the early recurrence within one year after the surgery for BCLC stage B HCC, according to the analysis results with a specificity of 85.1% and a sensitivity of 80.3%.

CONCLUSIONVariant clinicopathological factors were associated with early postoperative recurrence for BCLC stage B HCC and recurrence early after hepatectomy was more likely in patients with a higher score of the scoring system.

Objective: To summarize the characteristics of abdominal-pelvic unplanned reoperation (URO) in a cancer hospital. Methods: Retrospectively descriptive cohort research was adopted. The classification of diseases was based on ICD-10, and surgical classification was based on ICD-9-CM-3. Medical record summary database from 2008 to 2018 in Beijing Cancer Hospital was collected, and all URO information of abdominal-pelvic surgery was retrieve. The time of URO, disease type, surgery type and cause were statistically analyzed. Distribution of main disease incidence and constituent ratio, and the application of major surgery and surgery type composition ratio were analyzed as well. Results: From 2008 to 2018, a total of 46854 cases underwent abdominal-pelvic surgery (including gastrointestinal, hepatic-biliary-pancreatic, gynecological, urological, or esophageal cancer surgery) and 713 patients received URO (1.52%), including 486 males and 227 females (2.14:1.00) with a mean age of (58.1±12.2) years. A total of 246 patients (34.50%) had comorbidity, and with comorbidity: without comorbidity was 1.13:1.00. The hospital stay was (44.5±43.0) days, and the total cost was (178000±112000) yuan. There were 22 deaths (3.09%). The median interval between URO and the first operation was 8 (0 to 131) days. The highest rate of URO was 2.45% (89/3629) in 2012, while the lowest was 0.95% (53/5596) in 2015. The top 3 major cancer types of URO included colorectal cancer (222 cases, 31.14%), gastric cancer (166 cases, 23.28%) and esophageal cancer (45 cases, 6.31%). The cancer types with the highest URO rate included pancreatic cancer (3.97%, 30/756), gastric cancer (1.81%, 166/9171) and colorectal cancer (1.80%, 222/12333). The top 3 surgical procedures resulting in URO were rectal resection (109 cases, 15.29%), total gastrectomy (79 cases, 11.08%), and total pancreatectomy (64 cases, 8.98%). Focusing on 497 URO cases from 2012 to 2018, 465 cases (93.56%) followed relatively difficult grade III and IV surgery, while only 32 cases (6.44%) followed grade I and II surgery. The top 5 main causes of URO were bleeding (225 cases, 31.56%), anastomotic leak (225 cases, 31.56%), infection (89 cases, 12.48%), intestinal obstruction (53 cases, 7.43%), and wound dehiscence (35 cases, 4.91%), adding up to a total of 87.94% of all URO. Conclusion This study summarizes the epidemiology of abdominal - pelvic URO in our cancer institution, providing the solid baseline for future investigation of URO and the subsequent formulation of corresponding prevention and intervention measures.
