OBJECTIVETo investigate the association between the morphological features of biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa and the postoperative pathology.

METHODSFifty-one patients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa were retrospectively analyzed. Thirty-three patients underwent surgery. The morphology of lesions under endoscopy and histopathological findings of the surgical specimens were investigated.

RESULTSOf the 51 patients, 43 had superficial lesions similar to early gastric cancer under endoscopy, 8 were similar to advanced carcinoma. In the 33 surgical cases, high grade intraepithelial neoplasia of gastric mucosa was confirmed on postoperative pathological examination in 13 (39.4%) patients, adenocarcinoma was identified in the remaining 20 patients (60.6%), including 14 early gastric cancers and 6 advanced carcinomas. Thirteen cases with high grade intraepithelial neoplasia confirmed postoperatively were superficial elevated or flat lesions less than 20 mm.

CONCLUSIONSPatients with biopsy-diagnosed high grade intraepithelial neoplasia in the gastric mucosa have a high risk of cancer. Thus aggressive follow-up and appropriate surgical interventions are recommended to avoid misdiagnosis.

Diabetes surgery is a new concept in recent years, which means controlling blood sugar or curing diabetes through some surgical methods. From the commencement of bariatric surgery in the 1950s to the discovery of the special function of decreasing blood sugar after these surgeries in 1970s, and then the fast developing of diabetes surgery in the past 30 years, now there seems be a different answer to the question that if we can cure diabetes. In this article, we review the historical evolution, surgical procedure, potential mechanism and outlook of diabetes surgery.

OBJECTIVETo study the biological behavior of cardial cancer and its influence on surgical management.

METHODSComplete clinicopathologic data of 46 cases with cardial cancer undergoing radical gastrectomy was investigated retrospectively. The relationships between tumor Borrmann type, depth of invasion, growth pattern, lymph node metastasis and 5-year survival rate postoperative were analyzed.

RESULTSOf 46 cases, Borrmann type III, Type IV and Type II was 76% (35/46), 18% (8/46) and 6% (3/46) respectively; 5-year survival rate was 40% (14/35), 0 (0/8) and 100% (3/3) respectively. In respect of the depth of invasion, pT(2) was 31% (14/46) cases with 71% (10/14) lymph node metastasis; and 5-year survival rate was 64% (9/14). pT(3) was 15% (7/46) cases with 86% (6/7) lymph node metastasis; and 5-year survival rate was 57% (4/7). And pT(4) was 54% (25/46) cases with 92% (23/25) lymph node metastasis; and 5-year survival rate was 12% (3/25). The growth pattern in 87% (40/46) cases was infiltrative; and 5-year survival rate was 28% (11/40); the growth pattern in 13% (6/46) cases was expansive; and 5-year survival rate was 100% (6/6).

CONCLUSIOND(2)(+) radical total gastrectomy should be performed on the developed cardial cancer, and if necessary, resection of body and tail of pancreas should be chosen.

OBJECTIVETo investigate the association of SOX9 expression and clinicopathologic factors and prognosis of gastric cancer.

METHODSA retrospective cohort study including 112 gastric cancer patients admitted to the Zhejiang Provincial People's Hospital from 2004 to 2006 was performed. Immunohistochemical analysis was used to evaluate the expression of SOX9 in the 112 specimens of gastric cancer tissues and 70 non-cancerous tissues adjacent to the tumor.

RESULTSLow expression of SOX9 was seen in 5(7.1%) tissues out of 70 non-cancerous tissues adjacent to the tumor. A total of 94(83.9%) patients had varying expression of SOX9, of whom 51(45.4%) had overexpression. Univariate analysis demonstrated that the expression of SOX9 was significantly associated with Lauren classification (P<0.05), tumor invasion(P<0.01), lymph node metastasis(P<0.05), distant metastasis(P<0.05) and tumor stage(P<0.05), however there was no significant association between SOX9 expression and sex, age, histological type, histology differentiation or tumor size. Kaplan-Meier analysis showed that the 5-year survival rate of patients with SOX9 over-expression was significantly lower than that of patients with low expression(29.4% vs. 49.2%, P=0.031). Multivariate Cox regression analysis showed that histology differentiation(P=0.046), tumor invasion(P=0.001), and distant metastasis(P<0.01) were independent prognostic factors for gastric cancer, however the over-expression of SOX9 was not significant(P=0.948).

CONCLUSIONSThe expression SOX9 is associated with the growth, invasion, and metastasis of gastric cancer, as well as the prognosis. However, SOX9 expression is not an independent factor for the prognosis in patients with gastric cancer.

BACKGROUNDRecent studies have revealed that the reason for the low surgical resection rate of pancreatic carcinoma partly lies in its biological behavior, which is characterized by neural infiltration. This study aimed to investigate the clinical significance of radical pancreatoduodenectomy combined with retroperitoneal nerve, lymph, and soft-tissue dissection for carcinoma of the pancreatic head.

METHODSForty-six patients with pancreatic head cancer were treated in our hospital from 1995 to 2005. The patients were divided into two groups: radical pancreatoduodenectomy combined with retroperitoneal nerve, lymph and soft-tissue dissection (group A, n = 25) and routine Whipple's operation (group B, n = 21). There were no significant differences between the two groups in relation to age, gender and preoperative risk factors, and perioperative conditions, pathological data and survival rates were studied.

RESULTSThere were no significant differences in tumor size, surgical procedure time, postoperative complications, and time of hospitalization. However, the number and positive rate of resected lymph nodes in group A were significantly higher than those in group B (P < 0.05). The 1- and 3-year survival rate in group A were 80% and 53%, respectively, which was higher than those in group B (P < 0.05). There were significant differences in the survival rates between patients with and without nerve infiltration in group A (P < 0.05).

CONCLUSIONSRadical pancreatoduodenectomy combined with retroperitoneal nerve, lymph and soft-tissue dissection, can effectively remove the lymph and nerve tissues that were infiltrated by tumor. Meanwhile, this method can reduce the local recurrence rate so as to improve the long-term survival of patients.

OBJECTIVETo evaluate the serum concentrations of E- selectin, integrinbeta(1) subunit and intercellular adhesion molecule-1 in gastric cancer patients and their clinicopathological significance.

METHODSThe serum levels of adhesion molecules E- selectin,intercellular adhesion molecule- 1 (ICAM- 1), and integrinbeta(1) were measured by enzyme-linked immunosorbent assay (ELISA) in 47 health subjects (control group) and in 57 patients with gastric cancer (gastric cancer group) before operation and 7 days after operation. Serum levels of above three factors were compared between the two groups.

RESULTSThe serum concentrations of E- selectin, integrinbeta(1) subunit and ICAM- 1 were higher in gastric cancer group with positive rate of 24.6% ,33.3% ,28.1% respectively. ICAM- 1 and integrinbeta(1) were significant higher in gastric cancer group than that in the control group (P< 0.01),but there was no significant difference in E- selectin between two groups (P=0.64). Serum concentrations of E-selectin, ICAM-1,and integrinbeta(1) were significantly correlated with clinicopathological features as following: clinicopathological stage,invasion depth,lymph node involvement,and presence of distant metastases(P< 0.05,P< 0.01). The serum levels of E- selectin, ICAM- 1, and integrinbeta(1) were decreased significantly after radical resection of gastric cancer,but not in patients with unresectable tumor. Elevated levels of three molecules were significant prognostic factors for patients with gastric cancer,but it could not independently be used to evaluate tumor stage.

CONCLUSIONSSerum concentrations of E- selectin, ICAM- 1,and integrinbeta(1) may reflect tumor progression and metastasis.

OBJECTIVETo explore the pathogenesis, clinical features, diagnosis and treatment of Wernicke encephalopathy after major abdominal surgery.

METHODSClinical data of 10 patients with Wernicke encephalopathy after major abdominal surgery in the Zhejiang Provincial People's Hospital from 2000 to 2012 were retrospectively analyzed.

RESULTSWernicke encephalopathy occurred during 5 to 36 days (mean 22.9 days) after surgery. The main symptoms included vertigo, vagueness, blurred vision, and gait incoordination. MRI showed bilaterally symmetrical enhancement of T1 and T2 signal in thalamus, third ventricle, lateral ventricle and periaqueductal region. With treatment of vitamin B1, 6 patients were completely recovered, and 2 partly recovered, but 2 died.

CONCLUSIONSSurgeons should be aware of Wernicke encephalopathy when treating patients undergoing major abdominal operation who need prolonged fasting postoperatively. Early detection and timely supplement of vitamin B1 can avoid irreversible brain damage.

OBJECTIVETo study the cost-effectiveness, benefit and utility of infant hepatitis B vaccination in Shanghai from 1992 to 2001.

METHODSTo calculate the cost of hepatitis B vaccination by cost analysis method. Both the numbers of persons with HBsAg positive and patient with hepatitis B, cirrhosis and liver cancer decreased as the index of direct effect. To study the sick-time and the cost of treating hepatitis B, cirrhosis and liver cancer patients, a face to face questionnaire was used and quasi method was adopted to understand the effect of cure and the course of hepatitis B. The cost benefit analysis method was also used to calculate the cost benefit of HBV vaccine. The disability adjusted life years (DALY) was regarded as an index of utility to measure the disease burden.

RESULTSInput of 501,129.49 Yuan might have the result of reducing one liver cancer patient, ten cirrhosis patients, one hundred chronic hepatitis B patients and one thousand HBsAg positive people. The cost of hepatitis B vaccination was 0.24 hundred million Yuan during the past ten years in Shanghai, which had obtained the total benefit value of 41.22 hundred million Yuan, with a cost benefit ratio of 1:172 Yuan. It was estimated that the total disease burden of hepatitis B, cirrhosis and liver cancer patients was 59,762.55 DALY in order to reduce one DALY loss cost of 402.50 Yuan.

CONCLUSIONHBV vaccine inoculation in infants seemed to be a low-cost input and high-effect output strategy.
