Objective To explore the clinical significance of combined detection of plasma BNP and cTnⅠin predicting the prognosis of patients with acute heart failure.Methods 88 patients with acute heart failure were selected in emergency department of our hospital.According to the outcomes of patients'condition,the patients were divided into improved and discharged group (n =58)and died group (n =30).And 50 healthy people were selected as control group during the same period in our hospital.The changes of cTnI and BNP levels in the three groups were compared and analyzed.Results Compared with the control group,in the improved and discharged group and died group,the levels of cTnI were (1.09 ±0.91)ng/mL and (3.07 ±1.35)ng/mL,the levels of BNP were (182.76 ± 34.19)pg/mL and (226.84 ±51.73)pg/mL,which were significantly increased,the differences were statistically significant (t =9.15,9.90,26.11,13.99,all P <0.05 ).Compared with the control group,the patients before discharge in improved and discharged group,the levels of cTnI and BNP were (0.09 ±0.05)ng/mL and (65.33 ± 20.61)pg/mL,which were increased,the differences were not statistically significant (t =1.35,0.83,all P >0.05). Compared with the control group,the patients before death in died group,the levels of cTnI and BNP were (4.38 ± 1.59)ng/mL and (254.39 ±62.81 )pg/mL,which were significantly increased,the differences were statistically significant (t =12.09,13.52,all P <0.05).Compared with the improved and discharged group,the patients in died group admitted to hospital and before death,the levels of cTnI and BNP were increased significantly,the differences were statistically significant (t =6.16,3.59,12.06,13.25,all P <0.05).Compared with the cardiac function in patients with grade Ⅲ,the cardiac function in patients with grade Ⅳ,the levels of cTnI increased significantly,the difference was statistically significant (t =6.64,P <0.05).Conclusion Combined detection cTnⅠ and BNP has a guiding value for the prognosis of patients with acute heart failure.It provides a reference for clinical treatment.

OBJECTIVETo investigate the feasibility and short-term efficacy of laparoscopic resection of primary localized gastric gastrointestinal stromal tumors (GIST) by comparing with open surgery.

METHODSClinicopathological data of 167 gastric GIST patients undergoing operation in Zhongshan Hospital from June 2008 to December 2013 were retrospectively analyzed, among whom 55 received laparoscopic surgery and 112 underwent open surgery for primary local gastric GIST. Efficacy of different size and different location of GIST was compared between laparoscopic and open groups.

RESULTSThere was no conversion to open surgery in laparoscopy group. Compared with open surgery, laparoscopic resection for gastric GIST smaller than 5 cm or located at anterior wall, greater curvature, lesser curvature, was associated with similar operation time(P>0.05), but less blood loss, shorter post-hospital stay or flatus time(all P<0.05). The operative outcomes were similar between laparoscopic and open resection for gastric GIST bigger than or equal to 5 cm or located at posterior wall(all P>0.05), except the longer operation time in laparoscopy group(P<0.05). The incidence of postoperative complication did not differ between two groups. Laparoscopic group had 2 patients with gastroparesis and open group had 2 gastroparesis, 2 pulmonary infection, and 1 poor wound healing(all P>0.05), which all recovered after conservative treatment. During 7 to 84 months(median 35) of follow-up, no recurrence or hepatic metastasis was found in laparoscopy group, and 3 hepatic metastases in open group. There was no significant difference of recurrence-free survival between two groups(P>0.05).

CONCLUSIONLaparoscopic resection for gastric GIST is safe and effective in selected patients, especially for those with tumors smaller than 5 cm, or located at anterior wall, greater curvature, lesser curvature, whose short-term outcomes are better than open resection.

OBJECTIVETo explore the clinicopathological characteristics, efficacy, and prognostic factors for patients with duodenum gastrointestinal stromal tumor(GIST).

METHODSClinicopathological and follow-up data of 80 patients with duodenum GIST in the Zhongshan Hospital from January 2000 to December 2013 were analyzed retrospectively.

RESULTSThere were 38 male and 42 female patients with a median age of 54 years. The major symptoms were upper alimentary tract hemorrhage and abdominal pain. Thirty-nine patients received local tumor excision, 18 patients underwent segmental duodenectomy, 23 patients were subjected to pancreaticoduodenectomy, all these operations were R0 resection. Thirty patients received imatinib treatment after operation, and 11 among them had metastasis relapse. Recurrence-free survival rates of 1-, 3-, and 5-years were 96.2%, 90.6%and 78.6% retrospectively. Overall survival rates of 1-, 3-, and 5-years were 100%, 98.3% and 96.1%. Multivariate Cox analysis showed tumor size >5 cm, mitotic count >5 mitosis/50 HPF and intermediate/high NIH risk classification were associated with an increased risk of recurrence. The significant difference was not detected between the limited resection group and pancreaticoduodenectomy group in OS and RFS.

CONCLUSIONSSurgery is still the main treatment for duodenum GIST. The surgical program is mainly determined by the location and size of tumor. Imatinib therapy should be used if necessary.

OBJECTIVETo investigate the clinicopathological features of small gastrointestinal stromal tumors(GISTs) and to evaluate the efficacy of endoscopic therapy for GISTs.

METHODSClinicopathological and follow-up data of 418 patients with GISTs undergoing endoscopic therapy in the Zhongshan Hospital between January 2009 and July 2014 were analyzed retrospectively. All the cases were evaluated by the NIH risk classification and AIFP classification, and were grouped according to the tumor size and location. Nuclear atypia and mitotic count were used to evaluate the biological behavior of small GIST. Efficacy of endoscopic therapy was analyzed with follow-up data.

RESULTSOut of 418 patients, GISTs located in the esophagus was 14(3.3%), in the stomach 389(93.1%), in the duodenum 5(1.2%), in the rectum 10(2.4%). A total of 412(98.6%) patients were mainly spindle cells, and mitosis was not found in 320(76.5%) patients. In 389 small stomach GIST, 245(58.6%) were in fundic region. Cases were divided into four groups according to the size and the result revealed the bigger the size, the more the mitotic count. Nuclear atypia in the 1.5-1.9 cm group was significantly higher compared to other groups. Cases were divided into four groups according to the location and the result revealed the mitotic count was not associated to the location. While the nuclear atypia of stomach GIST was significantly higher than that of esophageal GIST and the nuclear atypia of rectum GIST was significantly higher than that of other positions. The median follow-up was 32(4-69) months. One case(gastric fundus GIST, >1.5 cm) presented local recurrence 23 months after operation and underwent endoscopic resection again. No recurrence or metastasis was found in other patients.

CONCLUSIONSEndoscopic resection technique is effective for small GISTs patients. The small GISTs with 0.4 cm diameter or less are often benign and should be followed up for long time. The small GISTs with 0.5 cm diameter or more possess the risk of malignancy, then surgical resection should be performed. Rectum small GISTs (except for 0.4 cm diameter or less) have worse biological behavior and should be removed.

OBJECTIVETo investigate the efficacy of targeted therapy combined with surgery in the treatment of recurrent and metastatic gastrointestinal stromal tumor(GIST).

METHODSClinicopathological and followed-up data of 318 patients with recurrent and metastatic GIST admitted in Zhongshan Hospital between January 2000 and December 2015 were analyzed retrospectively. According to different treatment methods, the patients were divided into four groups: surgery group (operation alone, 44 cases), target therapy group (imatinib alone, 108 cases), target therapy combined with surgery group (imatinib plus operation, 139 cases), other therapy group (chemotherapy, Chinese medicine and others, 27 cases). The progression-free survival (PFS) and overall survival (OS) of four groups were compared.

RESULTSThe baseline informations, such as age, gender, primary site, et al, were not significantly different (all P>0.05), but the recurrent and metastatic site was significantly different among 4 groups (P=0.000). The medial PFS of surgery group, target therapy group, target therapy combined with surgery was 16(95%CI: 4.9 to 27.0) months, 44 (95%CI: 30.9 to 57.1) months, 35 (95%CI: 26.5 to 43.5) months, respectively, and the latter 2 groups had significantly longer PFS than surgery group(P=0.000), while no significant difference was found between target therapy group and target combined with surgery group (P=0.251). The median OS of surgery group, target therapy group, target therapy combined with surgery, and other therapy group was 24 (95%CI: 9.0 to 39.0) months, 69(95%CI: 40.8 to 97.2) months, 92(95%CI: 78.0 to 106.0) months, 12(95%CI: 9.5 to 14.5) months. Target therapy group and target therapy combined with surgery group had significantly longer OS than surgery and other therapy groups (P=0.000), while the target therapy combined with surgery group had significantly longer OS than target therapy group(P=0.028).

CONCLUSIONTarget therapy combined with surgery can prolong the survival of recurrent and metastatic GIST patients.
