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.

Neuroanatomy knowledge is the key to improve the teaching quality of neurosurgery and anatomy teachers' participation in neurosurgery teaching can obviously improve teaching effect. Combined with case-based teaching, we enabled medical students to master the system knowledge from the basic to the clinical , cultivating their clinical thinking ability and the ability to solve clinical problems. Cooperation between clinical medicine teachers and basic medicine teachers can promote the update of knowledge, work out teaching plans together, and improve the quality of teaching.

Objective To investigate the significance of myelography for selecting operation methods in microendoscopic discectomy(MED).Methods A total of 196 patients with lumbar disc herniation diagnosed by CT/MRI received a myelography before MED.According to their clinical manifestations,signs,and outcomes of myelography,the patients were given three different operation methods.①Simple discectomy was performed in 105 patients with patent spinal canal,lateral impression at intervertebral level,and shift of the nerve root sleeve;②Discectomy with spinal decompression was performed in 70 patients with patent spinal canal and compression of the nerve root sleeve;③Discectomy with semilaminectomy was performed in 21 patients with patent spinal canal,semispherical compression of the nerve root sleeve,and 7-shaped nerve root.Results The operation time was 30~90 min(mean,50 min) and the intraoperative blood loss was 30~120 ml(mean,50 ml).No intraoperative complications occurred.Conversions to open surgery were required in 21 patients,including partial spinal stenosis in 16 patients and thickened vertebral plate in 5 patients.Follow-ups were carried out in 196 patients for 3~58 months(mean,34 months).According to the Japanese Orthopedic Association(JOA) scoring system,the final scores significantly increased postoperatively(25.86?2.96) than preoperatively(13.21?4.96)((t=)38.24,P=0.00).According to the Macnab and Watts standard,the rate of excellent or good results was 93.7%(164/175).Conclusions Myelography has an important reference value for selecting operation methods of microendoscopic discectomy in patients with lumbar disc herniation.

Fascin,an actin cross-linking protein found in membrane ruffles,microspikes,and stress fibers,induces membrane protrusions and increase cell motility in various transformed cells.The expression of fascin in epithelial neoplasms has only been described recently,and fascin overexpression may play an important role in the progress of neoplasms.This article reviews the current situation and the up to date progress of study concerning fascin and epithelial neoplasms.

Objective To analyze the clinical effects, as well as its advantages and disadvantages, of laparoscopic surgery for appendicitis in obese patients. Methods Clinical data of 80 obese patients receiving appendectomy, including 38 cases of open appendectomy and 42 cases of laparoscopic appendectomy, were analyzed retrospectively.The operative time, blood loss, analgesic and antibiotic use, postoperative fever, postoperative complications, length of hospital stay, and hospitalization cost were compared between the two operative methods. Results Conversions to open surgery were required in 2 patients in the laparoscopic group. There was no significant difference in operative time between the 2 groups (P >0.05).Compared with the open group, the laparoscopic group had less blood loss [(14.98 ±12.77) ml vs.(31.58 ±19.00) ml, t=-4.550, P=0.000], shorter time of postoperative antibiotic use [(2.7 ±1.0) d vs.(4.1 ±1.2) d, t=-5.470, P=0.000], less postoperative analgesics needed [5.0%(2/40) vs.26.3%(10/38),χ2 =6.802, P=0.009], less drainage [2.5% (1/40) vs.18.4% (7/38), χ2 =5.367, P=0.021], less postoperative fever [5.0%(2/40) vs.23.7%(9/38),χ2 =5.616, P=0.018], less postoperative wound healing [5.0%(2/40) vs.21.1%(8/38),χ2 =4.493, P=0.034], and shorter hospital stay [(5.9 ±3.2) d vs.(8.7 ±4.1) d, t=-3.345, P=0.001], but the higher cost of hospitalization [(7800 ±396) yuan vs.(4914 ±434) yuan, t=30.716, P=0.000]. Conclusion For obese patients with appendicitis, laparoscopic appendectomy has less surgical trauma, faster recovery, less postoperative pain, fewer complications,and shorter hospital stay, being a preferred method of treatment.

Objective To detect the expression of HSPA2 mRNA and protein in pancreatic cancer and corresponding adjacent nontumorous tissues, and investigate the expression of HSPA2 protein in pancreatic cancer and its association with clinicopathological characteristics.Methods Western blot and qPCR (real-time quantitative PCR) was used to evaluate HSPA2 expression in pancreatic cancer and corresponding adjacent nontumorous tissues.Immunohistochemistry was used to investigate the HSPA2 expression in pancreatic cancer and its association with clinicopathological characteristics.Results Both the mRNA and protein levels of HSPA2 were significant higher in pancreatic cancer tissues than those in their paired adjacent nontumorous tissues.High HSPA2 expression was detected in 68.8% (55/80) of pancreatic cancer tissues.HSPA2 protein expression was significantly associated with tumor differentiation, vascular invasion, and status of metastasis (P=0.011,0.005,0.012).Conclusion HSPA2 expression is elevated in pancreatic cancer, and positively correlated the process of invasion, metastasis and progression of pancreatic cancer.
