ObjectiveTo investigate the effect of TPN and Ulinastatin(UTI) on acute phase proteins (APP) metabolism in postoperative patients with advanced gastrointestinal carcinoma.MethodsSixty postoperative patients were randomly divided into four groups: control group( n =15) receiving routine iv infusion; UTI group( n = 15) receiving iv infusion and UTI; TPN group( n =15) and UTI+TPN group( n =15). The serum acute phase proteins and nitrogen balance were observed. ResultsThe decrease of serum APP was greater in control group and TPN group than in UTI group and UTI+TPN group( P

Objective To report the clinical features and inwardly rectifying potassium channel 18 (KCNJ18) gene mutation in a group of patients with thyrotoxic periodic paralysis (TTP).Methods Fiftyseven TTP cases (55 male and 2 female) were collected in our clinic from July 2002 to October 2011.The KCNJ18 gene was directly sequenced in 57 TTP patients and 50 health Chinese controls through the nested PCR.According to the results of gene screening,the clinical features of KCNJ18 patients and non-KCNJ18 patients were retrospectively summarized and analyzed.Results In 4 male patients with TPP,we found 3 novel heterogeneous mutations (p.Q126X,p.K360T,p.E388K) and 1 reported mutation (p.A200P) in the KCNJ18 gene.The age of onset was 19-25 years old,and the duration ranged from 2 to 8 hours.The 4 patients all presented severe muscle weakness.The attacks of muscle weakness preceded overt symptoms of hyperthyroidism in the 4 patients. Three patients showed recurrent weakness during the 13-28 months follow-up,while the episodic weakness never appeared when patients got euthyroid. Conclusions The mutations in the KCNJ18 gene are responsible for a part of Chinese patients with TPP.The patients with KCNJ18 mutations have a shorter disease course,severer manifestation,and higher prevalence of recurrence as compared with those TPP patients without KCNJ18 mutations.

Objective To explore the clinical effects of pedicled omentum in preventing anastomotic leakage after resection of colorcctal cancer complicated with intestinal obstruction.Methods The clinicopathologic data and anastomotic leakage rate of 102 patients with colorectal cancer undergoing resection from Dec.2012 to Dec.2015 were analyzed.Results Seven patients in the control group developed anastomotic leakage.Only 1 patient in the experimental group developed anastomotic leakage.The incidence of anastomotic leakage in the control group was 12％,while that in the experimental group was 2％ (x2 =4.250,P =0.039).Of the 7 patients complicating anastomotic leakage in control group,1 died of multiple organ failure,1 was cured with conservative treatment,and 5 were done with diverting stoma.The one leakage in experimental group was cured by conservative treatment.Conclusion Pedicled omentum is useful in the prevention of anastomotic leakage after resection of colorectal cancer in settings of intestinal obstruction.

Objective To investigate the clinical efficacy of combination treatment of Ambroxol,Ipratropium and Budesonide during perioperative period in elderly patients with cardiac adenocarcinoma and chronic obstructive pulmonary disease(COPD).Methods A total of 126 elderly patients aged over 65 years diagnosed as cardiac adenocarcinoma and COPD were selected,and no chemotherapy was given to them before operation.Patients were randomly divided into experimental group(n＝ 62)and control group(n＝ 64).Intravenous infusion of Ambroxol hydrochloride and atomizing inhalation of Ipratropium were given in both groups,and the experimental group received budesonide additionally.The pulmonary function,postoperative pulmonary atelectasis,pulmonary infection,antibiotics application and hospitalization after operation were compared between the two groups.Results The forced expiratory volume at the first second(FEV1),forced vital capacity(FVC)and FEV1/FVC were higher in experimental group than in control group [(1.79 ± 0.52)1 vs.(1.33 ± 0.38)L,(2.44 ±0.43)Lvs.(1.93 ± 0.36)L and(73.91 ± 8.17)％ vs.(62.87 ± 7.23)％,respectively,allP＜0.05].The postoperative pulmonary atelectasis and pulmonary infection were lower in experimental group than in control group(4.8％ vs.15.6％,6.5％ vs.18.8％,respectively,both P＜0.05).The time for antibiotics application after operation had no difference between the two groups[(4.81±1.20) days vs.(5.98 ± 1.17)days,P ＞ 0.05].There was a significant difference in postoperative hospitalization between the two groups [(8.37 ± 0.27) days vs.(11.80 ± 0.33) days,P ＜ 0.05].Conclusions The combination treatment of Ambroxol hydrochloride,Ipratropium and Budesonide during perioperative period achieves better therapeutic effects than does the combination treatment of ambroxol hydrochloride and ipratropium in elderly patients with cardiac adenocarcinoma and COPD.

Objective: To assess the application value of CT scanning in percutaneous pulmonary valve implantation (PPVI). Methods: A total of 19 patients with severe pulmonary regurgitation planed to receive PPVI in our hospital from 2014-05 to 2016-07 were studied. CT scan and transthoracic echocardiography (TTE) were conducted to collect the data of pulmonary root anatomy and to compare the difference of pulmonary annulus size measured by CT and TTE. The accuracy of pre-operative measurement was evaluated by the follow-up study at (1-26) months after the operation. Results: In all 19 patients, the mean anatomic measurements by CT were as follows: diameter of pulmonary annulus (24.3±3.5) mm, diameter of pulmonary sinotubular junction (25.4±4.0) mm, diameter at distal of main pulmonary artery (27.5±4.8) mm, diameter of right ventricular outflow tract (36.8±7.3) mm, length of main pulmonary artery (45.5±7.0) mm, diameter of left pulmonary artery (17.9±1.5) mm and diameter of right pulmonary artery (18.5±3.6) mm. The diameter of pulmonary annulus measured by CT was larger than TTE, P<0.05. During (1-26) months follow-up period, no patients suffered from stent fracture or translocation, peri-pulmonary valve regurgitation, obvious pulmonary regurgitation or coronary stenosis; 1 patient had increased flow rate at right pulmonary artery opening by stent blocking and 2 patients had residue mild stenosis of pulmonary valve. Conclusion: Pulmonary annulus size measured by CT and TTE was different; CT may precisely assess the morphology of pulmonary root with adjacent area which is important for pre-operative evaluation in PPVI patients.

Objective: To evaluate the changes of left and right ventricular function in patients after percutaneous pulmonary valve implantation (PPVI). Methods: A total of 8 patients with successful PPVI in our hospital from 2014-05-27 to 2015-03-25 were studied. The patients received pre-operative evaluation including clinical symptoms, plasma BNP levels, ECG, chest X-ray, echocardiography, CT and MRI examinations. Post-operative follow-up study was conducted at 6 months after PPVI to compare the ventricular functional changes. Results: The average age in 8 patients was 14-42 (25.4±8.1) years including 7 with tetralogy of Fallot correction and 1 with pulmonary stenosis plasty for 24 years. Echocardiography found that 3 patients with mid to large pulmonary regurgitation and 5 with large regurgitation. Compared with pre-operation, at 6 months after PPIV, all patients had decreased right ventricular end-diastolic diameter (RVEDD) as (44.0±4.8) mm vs (33.6±7.1) mm, right ventricular end-diastolic volume index (RVEDVI) (150.1±25.7) ml/m2 vs (111.4±39.1) ml/m2, RVESVI (107.8±21.5) ml/m2 vs (80.7±22.2) ml/m2 and right ventricular cardiac output (RV-CO) (6.8±1.3) L/min vs (4.9±0.8) L/min, but right ventricular ejection fraction (RVEF) was similar (40.5±6.2) % vs (39.5±9.9) %, P>0.05; while
increased LVEDD (42.9±4.4) mm vs (46.1±3.0) mm, P<0.05, but LVEDVI (61.8±15.0) ml/m2 vs (72.4±17.6) ml/m2, LVESVI (47.8±12.4) ml/m2 vs (41.0±10.4) ml/m2, LVEF (50.9±5.5) % vs (52.8±6.7) % and LV-CO (3.7±1.0) L/min vs (4.2±1.0) L/min were similar, allP>0.05. Conclusion: PPVI may decrease right ventricular preload, improve its reverse remodeling and maintain systolic function at normal level in relevant patients; while the impacts on left ventricular function and geometry should be further studied.

Objective: To explore the short and mid-term efficacy of device closure of patent foramen ovale (PFO) for treating the patients with PFO combining cryptogenic stroke (CS) and transient ischemic attack (TIA). Methods: A total of 56 PFO patients with CS and TIA receiving device closure in our hospital from 2009-05 to 2015-12 were retrospectively studied. Transthoracic echocardiography (TTE), electrocardiogram (ECG), chest X-ray were examined at 24h, 1 month, 3 and 6 months after theoperation; telephone visit was conducted every 6 months thereafter. Results: There were 54/56 PFO patients combining CS and 2 combining TIA; 53 (94.6%)patients received PFO occluder from Starway medical technology. Aspirin was used for 6 months after the operation. The patients were followed-up for the average of (34.67±23.24) months. No body suffered from post-operative stroke and TIA; no residual shunt was observed. Conclusion: The short and mid-term efficacy of device closure has been satisfactory for treating the patients with PFO combining CS and TIA; its overall clinical value should be further investigated in large population and long-term study.

OBJECTIVE: To assess the association of genomic instability of epithelial cadherin 1 (CDH1) gene and clinicopathological characteristics of gastric cancer. METHODS: In total 120 paraffin-embedded gastric cancer tissue specimen were prepared, and genomic DNA was extracted. The genomic instability of the CDH1 gene was analyzed by immunohistochemistry and silver staining PCR-single-strand conformation polymorphism. RESULTS: The number of information individuals (heterozygotes) was 98 for the D16S752 locus. The detection rates for microsatellite instability (MSI) and loss of heterozygosity (LOH) at the D16S752 locus and the positive rate of CDH1 protein were 19.39%, 16.33% and 51.02%, respectively. The detection rate of MSI in TNM stages I or II was significantly higher than that in stages III or IV (P<0.05) while the detection rate of LOH was significantly lower than that in stages III or IV (P<0.05). The positive rate of CDH1 protein in TNM stages III or IV was significantly lower than that in stages I or II (P<0.05). The detection rate of MSI of cases with lymph node metastasis was significantly lower than that of without lymph node metastasis (P<0.05) while the detection rate of LOH was significantly higher than that without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in patients with lymph node metastasis was significantly lower than that in patients without lymph node metastasis (P<0.05). The positive rate of CDH1 protein in MSI-positive group was significantly higher than that in MSI-negative group (P<0.05), and the positive rate of CDH1 protein in the LOH-positive group was significantly lower than that the LOH-negative group (P<0.05). CONCLUSION The genomic instability of the CDH1 gene is associated with the progression of gastric cancer. MSI at the D16S752 locus may be used as a molecular marker for early gastric cancer, while LOH at this locus mostly occurs in advanced gastric cancer and can be regarded as an effective indicators for malignancy evaluation and prognosis.

Objective To investigate the effects of miR-325-3p on the EMT, invasion and metastasis of gastric cancer cells by targeting CLDN1 gene. Methods We selected human gastric epithelial cell lines GES-1 and gastric cancer cell lines HGC27, SGC-7901, MKN-45 and MGC-803, and detected the expression of miR-325-3p and CLDN1. The targeting relation between miR-325-3p and CLDN1 were verified by dual luciferase report experiments, and the expression of miR-325-3p and CLDN1 in gastric cancer cells were intervened. qRT-PCR and Western blot were adopted to detect N-cadherin, vimentin and MMP2 expression in cells. CCK-8 assay, Transwell assay, flow cytometry were utilized to detect cell proliferation activity, invasion and apoptosis, respectively. Results Compared with GES-1 cells, miR-325-3p expression was decreased while CLDN1 expression was increased in MGC-803 cells (P < 0.05). CLDN1 was a target gene of miR-325-3p. Overexpression of miR-325-3p could inhibit the proliferation, invasion and EMT of gastric cancer cells, while promote the apoptosis of gastric cancer cells. However, the inhibition of miR-325-3p had the opposite effect (P < 0.05). The overexpression of CLDN1 could reverse the effect of miR-325-3p overexpression on the biological behavior of gastric cancer cells. Conclusion miR-325-3p can suppress CLDN1, inhibit the invasion, metastasis and EMT while promote the apoptosis of gastric cancer cells. miR-325-3p is expected to be a new target in gastric cancer treatment.

OBJECTIVETo compare the efficacy of proximal gastrectomy(PG) and total gastrectomy(TG) for adenocarcinoma of esophagogastric junction.

METHODSClinical trials comparing PG with TG for adenocarcinoma of esophagogastric junction published from 1990 to 2012 were searched in Cochrane library, Medline, Embase and China National Knowledge Infrastructure (CNKI), Wanfang Data. Review manager 5.0 was used for meta-analysis and outcome measures included mortality and complication morbidity, as well as nutritional state.

RESULTSA total of 10 studies including 2481 patients were identified and analyzed. The results showed no significant differences in the mortality(OR=1.00, P=0.99) and complication morbidity(OR=2.14, P=0.12) between PG and TG. However, anastomotic stenosis(OR=5.40, P<0.01) and reflux esophagitis(OR=7.12, P=0.01) were more frequently observed in PG group. The nutritional state in TG group was comparable with PG group(WMD=2.09, P=0.57).

CONCLUSIONTG is superior to PG in reducing the morbidity of anastomotic stenosis and reflux esophagitis.
