ABSTRACT

Objective@#To investigate the atypical computed tomography (CT) features of primary small intestinal lymphoma (PSIL), and its correlation with pathology.@*Methods@#From July 2007 to June 2018, at Ruijin Hospital, Shanghai Jiao Tong University School of Medicine, the clinical features and CT imaging data of 29 histopathologically diagnosed PSIL with atypical CT features were retrospectively analyzed.@*Results@#A total of 29 cases were all confirmed as Non-Hodgkin′s lymphoma including 23 cases of B cell lymphoma and six cases of peripheral T cell lymphoma. In 24 PSIL patients, the intestinal wall was unevenly thickened. While five cases had intra- and extra-intestinal masses. Images of four PSIL patients showed heterogeneous density at unenhanced CT scan, five cases presented with heterogeneous mild to moderate enhancement and five cases demonstrated with obvious enhancement at portal venous phase. Multiple ulcers in mucosa were found in 20 cases, and obviously abnormal mucosal enhancement was found in five cases, and 13 cases showed rough serosa layer of intestinal wall and the fat gap around the intestinal wall disappeared. Adjacent organs were involved in four cases and intestinal obstruction occurred in eight cases.@*Conclusion@#The atypical imaging of PSIL can be heterogeneous density of the lesion, heterogeneous or obvious enhancement at enhanced scan, multiple ulcers on the mucosal surface, thickening of the mucosal surface, blurred peripheral fat space, involvement of adjacent organs and intestinal obstruction.

ABSTRACT

Simulations can mimic the environment that refers to the surgery operation to improve the technical skills of the trainees. In this paper, we designed a new cardiac surgery simulative training system. The isolated pig heart was selected as the heart model. A mechanical device was designed to achieve the beating of heart model. At the same time, adjusting frequencies of mechanical movement could change the rating of heartbeat. In order to validate the rationality of the system, 12 non-medical specialty students and 12 medical specialty students were divided into two groups, which consecutively accepted seven-days of training for off-pump coronary artery bypass grafting using the cardiac surgery simulative training system. The time for completing bypass grafting before and after training were recorded. And the bridging outcomes of each trainee were assessed by 3 surgery cardiac surgeons using the object structured assessments of technical skill (OSATS) criteria. After training, each trainee could finish the bypass suturing in a shorter time than before training, and the scores of each trainee assessed by OSATS criteria were also improved. The results showed that the cardiac surgery simulative training system had better training effect in improving the surgical techniques, operation skills and proficiency of surgical instruments of trainees.

ABSTRACT

<p><b>OBJECTIVE</b>To study the clinicopathological features and prognosis of gastric stump cancer (GSC) following subtotal gastrectomy for gastric cancer, to compare the clinicopathologic differences between narrow GSC and generalized GSC, and to compare the prognosis between GSC and primary proximal gastric cancer (PPGC) after radical resection.</p><p><b>METHODS</b>Literatures of GSC-associated clinical study were searched by computer from the Cochrane Library, Medline, PubMed, CNKI, Wanfang and VIP databases, and the retrieval period was from the establishment of database to December 31, 2017.</p><p><b>INCLUSION CRITERIA</b>(1) GSC was defined as a carcinoma arising in the gastric remnant after radical gastrectomy for gastric cancer, and confirmed by the pathological or histological examination, the elapsed time from the initial operation was not considered in the definition. (2) Retrospective or prospective clinical cohort study. (3) Study included at least one of below items: gender, anastomotic type in gastric cancer surgery, the interval between the initial surgery and diagnosis of GSC, the location, treatment, pathological differentiation, pathologic stage, lymph node metastasis rate and prognosis of GSC. (4) When similar studies were reported by the same institution or author, either the better quality study or the newest publication was chosen.</p><p><b>EXCLUSION CRITERIA</b>(1) Abstracts, reviews, case reports, meeting record, editorials and repeated research. (2) Studies including patients with initial non-gastric cancer. In this study, gastric stump cancer(GSC) after gastric cancer was divided into two groups: the incidence without limit interval time (generalized GSC group) and above 10 years (narrow GSC group). Selective trials were Meta-analyzed by the Stata13.0 software and statistical analysis was performed using SPSS 21.0 software.</p><p><b>RESULTS</b>A total of 27 literatures were finally enrolled, which comprised 1463 GSC patients, including 1146 males and 317 females. The generalized group and narrow GSC group had 921 and 542 patients respectively. The generalized GSC group and the narrow GSC group did not significantly differ in terms of previous reconstruction mode, types of differentiation, pathologic T staging, postoperative pathology tumor-node-metastases staging, and distant metastasis rate (χ=2.341, 0.926, 0.350, 0.965, 2.311 respectively, all P>0.05). As compared to generalized GSC group, narrow GSC group had higher ratio of male patients (82.8% vs. 75.7%, χ=9.909, P=0.002), more lesions locating in anastomotic stoma (37.8% vs. 26.1%, χ=18.091, P=0.000), higher ratio of patients undergoing radical resection (84.2% vs. 70.3%, χ=11.738, P=0.001), higher positive rate of postoperative lymph node (45.8% vs. 34.5%, χ=6.319, P=0.012), and larger size of tumor [(5.9±2.2) cm vs. (4.5±1.9) cm, t=9.151, P=0.000]. The overall 5-year survival rate and postoperative pathology stage III(-IIII( survival ratio in narrow GSC group were higher compared to general GSC group (42.7% vs. 30.6% and 27.5% vs. 18.1%, respectively), which were significantly different (χ=10.938, P=0.000; χ=4.128, P=0.042), while the postoperative pathology stage I(-II( survival ratio was not significantly different between two groups (67.3% vs. 67.0% respectively, χ=0.015, P=0.92). There was no significant difference in the 5-year survival rate between GSC with radical resection and PPGC(RR=1.04, 95%CI:0.79-1.36, P=0.805) and the 5-year survival rate of same postoperative pathology stage was not significantly different between two groups (I(-II( stage: RR=1.08, 95%CI:0.93-1.26, P=0.328; III(-IIII( stage: RR=0.59, 95%CI:0.33-1.04, P=0.111).</p><p><b>CONCLUSIONS</b>There are some different clinicopathological features between the generalized and the narrow GSC after gastric cancer surgery. The prognosis of GSC after radical resection is similar to primary proximal gastric cancer.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the prognostic value of the tumor-ratio-metastasis (TRM) staging system for carcinoma in the remnant stomach(CRS).</p><p><b>METHODS</b>Clinicopathological data of 91 CRS patients who underwent surgery at Peking University People's Hospital between March 1992 and December 2017 were retrospectively analyzed. According to the ratio of metastatic lymph node to dissected lymph node, the R staging was obtained, and the pN staging was replaced by the R staging to create the TRM staging. To compare the predictive accuracy of TRM and tumor-node-metastasis (TNM, UICC version 7), the R staging and pN staging were included in the prognostic factor analysis model, and the survival curve, c-index, and 95% confidence interval (CI) of the TRM staging and TNM staging system were compared. A higher c-index value means higher prediction accuracy.</p><p><b>RESULTS</b>Of 91 CRS patients, 77 were male and 14 were female with the mean onset age of (65.2±10.4) years. The mean interval from the first operation to CRS onset was 156(6-600) months. The primary diseases of 49(53.8%) cases were benign and of 42(46.2%) cases were malignant. The median number of retrieved lymph node (RLN) was 8 (0-38), and 64 patients (70.3%) had an RLN ≤15. Lymph node metastasis occurred in 50 patients (54.9%). pN staging result was as follows: 41 cases in N0 stage, 14 in N1 stage, 19 in N2 stage, and 17 in N3 stage. R staging result was as follows: 41 cases in R0 stage, 4 in R1 stage, 19 in R2 stage, and 27 in R3 stage. TNM staging result was as follows: 13 cases in stage I(, 25 in stage II(, 10 in stage III(a, 23 in stage III(b, and 6 in stage III(c. TRM staging result was as follows: 13 cases in stage I(, 24 in stage II(, and 4 in stage III(a, 18 in stage III(b, and 18 in stage III(c. Univariate analysis showed that tumor diameter ≥7 cm (HR=2.696, 95%CI: 1.307-5.563, P=0.007), T3-4 stage (HR=4.350, 95%CI: 1.949-9.707, P=0.000), N2-3 stage (HR=1.883, 95%CI: 1.167-3.038, P=0.009), R2-3 stage (HR=1.642, 95%CI: 1.026-2.628, P=0.039), TNM III(-IIII( stage (HR=2.448, 95%CI:1.490-4.021, P=0.000), and TRM III(-IIII( stage (HR=2.504, 95%CI:1.515-4.137, P=0.000) were related to prognosis. Tumor diameter, pT staging, and pN staging were included in the Cox multivariate analysis, and the result showed that pT staging (HR=5.507, 95%CI:2.254-13.454, P=0.000) and pN staging (HR=1.698, 95%CI: 1.022-2.789, P=0.041) were independent risk factors for overall survival of CRS in this group. While R staging replaced pN staging and was included in the Cox multivariate analysis together with tumor diameter and pT staging, the result showed that R staging was not an independent risk factor for CRS in this group (HR=1.622, 95%CI: 0.866-2.329, P=0.164). Survival curve revealed pN and TNM staging systems provided better stratified curves according to each staging than R and TRM staging systems. The overall survival c-index of TNM and TRM staging systems was 0.813(95%CI: 0.732-0.826) and 0.809(95%CI: 0.741-0.847) respectively, and no significant difference in predictive accuracy was found (P=0.693). In 42 patients with primary malignance, the overall survival c-index of TNM and TRM staging systems was 0.774(95%CI: 0.589-0.901) and 0.761(95%CI: 0.596-0.912) respectively, and there was no significant difference in predictive accuracy as well (P=0.881).</p><p><b>CONCLUSION</b>TRM staging is not superior to TNM staging (7th UICC) in evaluating the resected samples of CRS.</p>

ABSTRACT

Objective To investigate the effects of Panax notoginseng saponins (PNS) on the cerebral water content and thrombin in the rats with intracerebral hemorrhage (ICH), and explore its mechnism for treating ICH. Methods SD male rats were randomly divided into blank group, sham operation group, model group and treatment group, and time points of 6, 24, 48, 72 h and 7 d were observed. ICH rat model was induced by collagenase and heparin in saline solution injected into caudate nucleus. The treatment group was injected PNS intraperitoneally once a day, and the cerebral water content was assessed by dry-wet weight method. Both content of fibrinogen (FIB) and thrombin clotting time (TT) in 48 h were measured. Results The cerebral water content of model group increased at every time point compared with blank group and sham operation group (P0.05). Conclusion PNS may play a role in treating ICH by decreasing cerebral water content, FIB and TT of ICH rats.

ABSTRACT

@#Objective To investigate the physiological and psychological symptoms of drug abusers under rehabilitation period through labor.Methods A self-designed clinical symptoms questionnaire and Eysenck Personality Questionaire (EPQ) were used to evaluate 1 004 drug abusers under rehabilitation period through labor, and the related symptoms were analyzed.Results The mainly physiological symptoms were fatigue, forgetfulness, aching pain of joints, arrhythmia and discomfort of limbs, and the mainly psychological symptoms are drug craving, insomnia and anxiety. The mean scores of P and E were higher in those who had the drug craving symptoms ( P<0.01), and the mean scores of N were higher in those who had the insomnia or anxiety symptoms ( P<0.01).Conclusion The mainly physiological symptoms of drug abusers under rehabilitation period through labor are fatigue, forgetfulness, aching pain of joints, arrhythmia and discomfort of limbs, which are probably caused by the unbalance of the nervous and internal secretive systems, and the plastisity of the nervous system. The psychological symptoms may due to the effect of morphine and the personality of the drug abusers.
