Objective: To study the relationship between the level of hyaluronic acid(HA) in peritoneal fluid in patients with gastric cancer and the invasion or diffusion of the cancer. Methods: The concentration of peritoneal fluid hyaluronic acid (PFHA) was determined by RIA in 48 patients with gastric cancer prior to and after operation. The PFHA from 23 non carcinoma patients were taken as control. The peritoneal fluid was obtained by the implantable Infuse Port. Results: The average PFHA level of gastric cancer group[(913.01?170.69) ?g/?g] was significantly higher than that of the non carcinoma control [(362.39?168.82) ?g/?g]. The PFHA concentration were significantly higher in groups of pTNM Ⅲ+Ⅳ [(1 094.42?127.65) ?g/?g] than that in groups of pTNM Ⅰ+Ⅱ [(814.03?232.22) ?g/?g]. The PFHA level in the radical resection group was significantly reduced a month after operation, and there were no significantly changes in patients received palliative resection. Conclusion: These findings suggest that the elevation of PFHA may be related to the peritoneal invasion and diffusion potential of gastric cancer. The PFHA level shows a decreasing tendency in patients received radical resection.

BACKGROUND:Titanium-niobium al oy holds high biomechanical strength and low elastic modulus that is close to the human cortical bone, so it has been extensively used as implant materials of dental, orthopedics and artificial hip joints. OBJECTIVE:To observe the biomechanical strength and cytocompatibility of porous titanium-niobium al oys with different porosities. METHODS:Porous titanium-niobium al oys with the porosity of 40%and 70%were prepared using powder metal urgy technology. Afterwards, the pore size, elasticity modulus and compressive strength of the two al oys were detected. Then the rabbit bone marrow mesenchymal stem cel s were seeded onto the 40%and 70%porous titanium-niobium al oys, and cel adhesion and proliferation were observed at 3, 24 and 72 hours after inoculation, respectively. RESULTS AND CONCLUSION:Pore size of porous titanium-niobium al oys with rough surface was 200-500μm, and both main pore size was 350 and 400μm, and there was three-dimensional connectivity between the pores;in the 70%group, honeycombed pores were partly fractured, and connected mutual y;pores distributed unevenly and there was little communication between the pores in the 40%group. In addition, both groups had high compressive strength and low elastic modulus, but there was no difference between the two groups. Furthermore, both two al oys promoted cel adhesion, and the number of cel adhesion in the 70%group was significantly higher than that in the 40%group (P<0.05), and extracel ular matrix could be found in the 70%group. These results show that porous titanium-niobium al oy with the porosity of 70%is significantly conducive to cel adhesion.

Objective To explore the value of biopsy of lymph nodes alongside of internal jugular vein in surgery for papillary thyroid carcinoma(PTC) patients at CN 0 stage.Methods Clinical data of 103 PTC patients with operation at CN 0 stage were retrospectively analyzed.The lymph node ratio alongside of internal jugular vein was counted,and factors,such as gender,age,tumor size,capsular foreign invasion were analyzed.Results Of all 103 cases of papillary thyroid carcinoma at CN 0 stage,32 cases had lymph node metastasis alongside of internal jugular vein(31.1％).Meanwhile 31 cases had the thyroid capsule invasion,and 21 cases had lymph node metastasis alongside of internal jugular vein(67.7％).The rest 72 cases had no the thyroid capsule invasion,and 11 cases had lymph node metastasis alongside of internal jugular vein(15.3％),the difference was statistically significance(x2 =27.85,P ＜ 0.05).Conclusion Routine biopsy of lymph nodes alongside of internal jugular vein is necessary of papillary thyroid carcinoma patients at CN 0 stage.Whether the thyroid capsule is invased which is important factors affecting lymph node metastasis alongside of internal jugular vein.

Objective:To investigate the clinical characteristics, diagnosis, and treatment of primary pancreatic lymphoma (PPL). Methods:Clinical data of six PPL cases diagnosed and treated in the Tianjin Medical University Cancer Hospital were retrospectively analyzed. Results:In all cases, the primary clinical manifestations were abdominal pain, jaundice, and weight loss. The tumor marker level, including CA19-9, of all the cases was within the normal range, with five of the cases misdiagnosed as pancreatic cancer and one misdiagnosed as stomach cancer. In three cases, the pancreatic mass was located at the head of the pancreas, whereas in the other three, the mass was located at the body or tail. Pancreaticoduodenectomy was conducted in one case, laparotomy and biopsy in three cases, and B ultrasound-guided biopsy in the other two cases. All cases were diagnosed as PLL (B cell type non-Hodgkin's lymphoma). Ex-cept for one patient who left the hospital after surgery, the other five underwent chemotherapy. In addition to the death in one case be-cause of postoperative gastrointestinal bleeding, the survival times were 133, 73, 35, 12, and 10 months in the remaining cases. Conclu-sion:PPL is extremely rare in clinical practice, and the treatment methods and prognosis for the disease significantly differ from those for pancreatic cancer. PPL is easily misdiagnosed in clinical practice, which results in unnecessary treatment measures.

Objective To investigate the efforts of CD4+ CD25+ regulatory T (Treg) cell adjustment of Treg cells proportion in peripheral blood of patients with gastric cancer before or after surgery.Methods The peripheral blood samples were collected from 10 healthy volunteers,58 gastric cancer patients 2 days before and 7 days after operation.The proportion of Treg cells in peripheral blood were detected by flow cytometry.Results CD4+ CD25+ Treg cell in peripheral blood of patients with gastric cancer increased significantly compared with that of healthy control group (1.1±0.4) ％ / (1.5±0.5) ％ (P ＜ 0.05),and further increased after operation (1.5±0.55) ％ / (1.9±0.8) ％ (P ＜ 0.01).Conclusion The anti-tumor activity in gastric cancer patients is inhibited and surgery may be involved immune defection to decrease this effort.
