Objective To find out the relationship between lymph node metastasis and clinical pathological specificity, the prognostic factors for the purpose of improving survival of early gastric cancer (EGC) and quality of life. Methods The clinical data of the 338 EGC patients from July 1999 to June 2009 was analyzed retrospectively, includirg the possible relationship of lymph node metastasis, the size of tumor,types of histopathology,depth of infiltration. Using Kaplan-Meier method to process suvival rate,immunohistochemistry method to detect the micrometastasis. Results Lymphnode metastasis was relative to the size of tumor, depth of infiltration (P < 0.05 or < 0.01). Total 5-year survival rate was 92.1%, intramucosa 5-year survival rate 97.1%, submucosa 5-year survival rate was 85.7% in 63 followed up patients, the survival rate of EGC was related with depth of infiltration and size of tumor (P = 0.043,0.004). Conclusion By precisely estimating depth of infiltration, the size of tumor and correct estimating the state of lymph node metastasis, choosing right 5-year surgical protocol can improve EGC survival rate and prognosis.

Objective To explore the characteristics of lymph node metastasis in gastric stump cancer and the efficacy of surgical treatment. Methods The clinical data of 42 patients with gastric stump cancer (test group) and 56 patients with primary cancer in the upper stomach (control group) who were admitted to The First Affiliated Hospital of Dalian Medical University from January 1994 to January 2008 were retrospectively analyzed. All data were analyzed by t test and chi-square test. The survival of the patients and lymph node metastasis rate were analyzed using the Kaplan-Meier method and Log-rank test, respectively. Results The metastasis rates of lymph nodes 1-3 of the test group and control group were similar (43%-61%), with no significant difference between the 2 groups (χ2 = 0.752, 0. 833, 0. 678, P > 0. 05). The metastasis rates of lymph nodes 7-9 of the test group and control group were 22% , 18% , 25% and 46% , 25% , 30% , respectively, and this was signifi-cantly different between the 2 groups (χ2 = 2. 168, 3. 263, 5. 761, P < 0. 05). The metastasis rates of lymph nodes 10-14 were 47% , 36% , 31% , 20% and 25% in the test group, which were significantly higher than 33% , 34% , 19% , 6% and zero in the control group, respectively (χ2 =3.225, 1.883, 3.945, 4.137, 6.823, P <0.05). The metastasis rate of lymph node no. 16 was zero in the test group and 23% in the control group. The metastasis rate of jejunal mesenteric lymph nodes was 27% in the test group and zero in the control group. The accumulative 5-year survival rate of patients was 38% in the test group and 48% in the control group, and this was significantly different (χ2 =4. 165, P<0.05). The overall 5-year survival rate of patients with radical resection was not significantly different between degree A (54%) and B (57%) (χ2 = 0. 622, P > 0. 05). Conclusions Gastric stump cancer has a unique pattern in lymph node metastasis. Surgical resection is effective in improving the prognosis of patients with gastric stump cancer.

Objective To discuss the effect of pylorus-preserving gastrectomy for early gastric cancer(EGC). Methods Between August 1995 and December 2005, 52 cases of EGC underwent pyloruspreserving gastrectomy(PPG) and 159 cases of EGC underwent distal gastrectomy(DG), Clinicopathlogic data and follow-up results of the two groups were analyzed retrospectively, and gastric emptying and gallbladder function of 15 cases PPG and 17 cases DG were compared at the same time.Results Compared with DG group, patients in PPG group maintain the body weight, gastric emptying and gallbladder function. There was no significant difference between PPG group (92. 3% ) and DG group (93.1% ) in overall 5-year survival rate ( P = 0. 881 ). The 5-year survival rate of the the PPG group with lymph node dissection was D1 100%, D1+α 92. 3%, D1+β 88.9%, D2 87. 5% respectively.Conclusions For early gastric cancer, the pylorus-preserving gastrectomy is effective for maintaining the postoperative function with similar long term survival as that of distal gastrectomy.

Objective To analyze the clinicopathologic features,effect of surgical treatment and prognosis of elderly patients with gastric cancer.Methods The records of 84 elderly patients(aged 80 years or above) with gastric cancer who underwent operation in our hospital from 2000-2008 were analyzed retrospectively.Results Ten patients had early gastric cancer(1a,8 cases,1b,2cases),stage II 12 cases,stage III 45 cases(53.6%) and stage IV 17 cases.Among them,81% patients had one or more co-morbidities.Cardiovascular disease was present in 43 cases(51.2%).Resection rate was 85.7%(72/84).Radical resection rate was 60.7%(51/84).Limited nodal dissection(

In this study, the time-dependent changes on dynamic computed tomograph (CT) of radiation-induced liver injury in gastric cancer patients was examined. The CT images of 52 gastric cancer patients who had received chemoradiotherapies were reviewed on the PACS system. Dynamic CT scan was performed in all the subjects. Our results showed that 18 patients were found to have radiation-induced liver injury. The CT findings of radiation-induced liver injury in gastric cancer patients tend to show up one month after radiation treatment. The damaged area was of low density on all three phases, and then it was enhanced on portal vein phase or delay phase. The focal radiation reaction of liver without basic disease vanished 9-11 months later after treatment. We are led to conclude that dynamic CT is of help in the diagnosis of CRT-induced liver injury, and it may be the method of choice for following up the whole course of the CRT-induced liver injury, i.e., form hepatic damage to healing. The classification of CT findings we recommend can avoid the influence of technological factors, and thereby serve as a better guide for treatment of CRT-induced liver injury.

OBJECTIVE: To evaluate the relation between the incidence of sinusitis and the position of the inferior border of the middle concha related to the semilunar hiatus. METHOD: Clinical data of 94 cases (185 sides of paranasal sinus) diagnosed by CT detection, operative findings and clinical features were analyzed. The middle concha was divided into 3 types according the position of its inferior border related to the semilunar hiatus: superior hiatus type (the inferior border of the middle concha superior to the semilunar hiatus), hiatus type (the inferior edge of the middle concha at the level of the semilunar hiatus) and inferior hiatus type (the inferior edge of the middle concha inferior to the semilunar hiatus). Statistic analysis were taken for comparing the incidence of sinusitis among the position of the middle concha and other anatomical variations such as deviation of nasal septum, pneumatization of middle concha, paradoxical curve of the middle concha, variations of the uncinate process, ethmoidal bulla enlargements, Haller cells and agger cell pneumatization. RESULT: There was no significant difference of the anatomic variations by comparing the superior hiatus type together with the hiatus type versus the inferior hiatus type (P > 0.05). But the incidence of sinusitis in each type was remarkably different, the superior hiatus type and hiatus type had more sinusitis than the inferior hiatus type. Furthermore, the second and third type of sinusitis in the superior hiatus type and hiatus type weighted over the inferior hiatus type (P < 0.01), while the first type didn't (P > 0.05). CONCLUSION There is no association between the position of the middle concha and the anatomic variations of the nasal cavity and paranasal sinus. The poorly developed middle concha may acts as a risk factor for sinusitis and nasal polyps.

Objective To investigate the use of parenteral nutrition preparations in Jiangsu Province,and to provide reference for the standardized management of parenteral nutrition preparations.Methods 720 cases using parenteral nutrition preparations from January 2017 to June 2017 in the department of general surgery of 12 hospitals in Jiangsu province were selected.The rate of nutritional risk screening,the indications of parenteral nutrition,the way of infusion,the rationality and economy of the prescriptions were retrospectively evaluated.The calorie,amino acid content,non-protein calorie/nitrogen ratio,glycolipid ratio and cation concentration of the patients received total parenteral nutrition were calculated.Results The total costs of parenteral nutrition preparations of 720 cases were 1.614 1 millions,and 346 cases did not have the indications for parenteral nutrition.The results of prescription comment showed that only 16 patients were screened for nutritional risk by Nutritional Risk Screening 2002 tool at admission.544 cases were intravenous dripped with amino acid and fat emulsion from peripheral vein.In the 176 total parenteral nutrition prescriptions,there were 39 non-protein calorie/nitrogen ratio cases,15 glycolipid ratio cases,69 cation concentration cases,61 calorie cases and 32 amino acid content cases failing to comply with the recommendation of the guidelines.Only 31 total parenteral nutrition prescriptions were completely reasonable.Conclusion The costs of parenteral nutrition preparations used in hospitals of Jiangsu are high but the rate of rationality is low.Nutrition support team should be established to regulate the use of parenteral nutrition preparations and save medical resources.

Objectives:To explore health-related quality of life (HRQoL) and identify its associated variables in Chinese patients with Philadelphia-negative myeloproliferative neoplasms (MPNs) .Methods:In this cross-sectional study, anonymous questionnaires were distributed to adult patients with MPNs to assess symptom burden measured by MPN-10 and HRQoL measured by Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) and the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) .Results:The data from 1405 respondents with MPNs, including 645 (45.9%) with essential thrombocythemia (ET) , 297 (21.1%) with polycythemia vera (PV) , and 463 (33.0%) with myelofibrosis (MF) , were analyzed. 646 (46.0%) respondents were male. The median age was 56 (range, 18-99) years. The mean MPN-10 scores were 13.0±12.7, 15.0±14.7, and 21.0±16.6 ( P<0.001) , and the physical component summary (PCS) and mental component summary (MCS) scores were 48.0±8.5, 47.0±9.0, and 42.0±10.0 ( P<0.001) and 51.0±11.0, 50.0±10.8, and 49.0±11.1 ( P=0.002) for respondents with ET, PV, and MF, respectively. Respondents with MF reported the lowest score of physical functioning, role functioning, emotional functioning, cognitive functioning, social function, and global health status (all P<0.01) and the highest score of fatigue, pain, dyspnea, appetite loss, diarrhea, and financial problems (all P<0.05) in EORTC QLQ-C30. Multivariate analyses revealed that higher MPN-10 scores were significantly associated with lower PCS (-0.220 to -0.277, P<0.001) and MCS (-0.244 to -0.329, P<0.001) scores; increasing age (-1.923 to -4.869; all P<0.05) , lower PCS score. Additionally, comorbidity (ies) , symptom at diagnosis, splenomegaly, anemia, unknown driver gene, and higher annual out-of-pocket cost were significantly associated with lower PCS and/or MCS scores. However, age ≥ 60 years, urban household registration, concomitant medication, and receiving ruxolitinib therapy in respondents with MF were associated with higher MCS scores. Weak correlations were found between MPN-10 score (except the subscale of appetite loss and constipation) and EORTC QLQ-C30 score in majority of subscales in respondents with ET (| r| = 0.193-0.457, all P<0.001) , PV (| r| = 0.192-0.529, all P<0.01) , and MF (| r| = 0.180-0.488, all P<0.001) , respectively. Conclusions:HRQoL in patients with MPN was significantly reduced, especially in patients with MF. Sociodemographic and clinical variables were significantly associated with the HRQoL in patients with MPNs.

Objectives:To investigate the clinical and genetic features of young Chinese patients with myeloproliferative neoplasms (MPN) .Methods:In this cross-sectional study, anonymous questionnaires were distributed to patients with MPN patients nationwide. The respondents were divided into 3 groups based on their age at diagnosis: young (≤40 years) , middle-aged (41-60 years) , and elderly (>60 years) . We compared the clinical and genetic characteristics of three groups of MPN patients.Results:1727 assessable questionnaires were collected. There were 453 (26.2%) young respondents with MPNs, including 274 with essential thrombocythemia (ET) , 80 with polycythemia vera (PV) , and 99 with myelofibrosis. Among the young group, 178 (39.3%) were male, and the median age was 31 (18-40) years. In comparison to middle-aged and elderly respondents, young respondents with MPN were more likely to present with a higher proportion of unmarried status (all P<0.001) , a higher education level (all P<0.001) , less comorbidity (ies) , fewer medications (all P<0.001) , and low-risk stratification (all P<0.001) . Younger respondents experienced headache (ET, P<0.001; PV, P=0.007; MF, P=0.001) at diagnosis, had splenomegaly at diagnosis (PV, P<0.001) , and survey (ET, P=0.052; PV, P=0.063) . Younger respondents had fewer thrombotic events at diagnosis (ET, P<0.001; PV, P=0.011) and during the survey (ET, P<0.001; PV, P=0.003) . JAK2 mutations were found in fewer young people (ET, P<0.001; PV, P<0.001; MF, P=0.013) ; however, CALR mutations were found in more young people (ET, P<0.001; MF, P=0.015) . Furthermore, mutations in non-driver genes (ET, P=0.042; PV, P=0.043; MF, P=0.004) and high-molecular risk mutations (ET, P=0.024; PV, P=0.023; MF, P=0.001) were found in fewer young respondents. Conclusion:Compared with middle-aged and elderly patients, young patients with MPN had unique clinical and genetic characteristics.
