Chinese Journal of Current Advances in General Surgery 2004;0(06):-
Objective:To investigate the proper method for treating traumatic chyloperitoneum. Methods: A retrospective analysis was performed on clinical data of 4 cases of traumatic chyloperi- toneum admitted to our hospital in recent 26 years. Results: All 4 cases were cured after conserva- tive treatment. Conclusion: Perdominantly integrated therapy including absolute diet,total parrenter- al nutrition(TPN) and abdominal cavity drainage can be the effective method for the treatment of trau- matic chyloperitoneum.

Journal of International Oncology 2017;44(4):257-261
Objective To investigate the biological effects of nonthermal plasma (NTP) combined with X-ray irradiation on human hepatocellular carcinoma in nude mice.Methods By subcutaneous inoculation, tumor models of human hepatocellular carcinoma HepG2 in nude mice were established, and these mice were divided into control group, NTP treatment group, X-ray irradiation group, combined treatment group.The changes of tumor microenvironment were observed using hematoxylin-eosin (HE) staining.The terminal deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) was used to determine the level of neuronal apoptosis in tumor tissues.The expression of metal matrix proteinase-2 (MMP-2) was detected by immunohistochemical assay.Transmission electron microscope was used to observe cell structure changes.Results The final tumor volumes of control group, NTP treatment group, X-ray irradiation group, combined treatment group were (543.96±108.45), (436.54±65.49), (351.66±56.68), (281.97±35.60)mm3, with a statistically significant difference (F=9.63, P=0.01), and the difference between X-ray radiation group and the combination treatment group was significant (P=0.05).HE staining showed that there was a larger area of necrosis in the combined treatment group compared with the other groups.TUNEL showed that the apoptotic indexes were (0.95±0.13)%, (5.82±0.26)%, (7.53±0.43)%, (11.07±0.35)% respectively, with a statistically significant difference (F=547.76, P=0.00), and the difference between X-ray radiation group and the combination treatment group was statistically significant (P=0.00).The immune scores of each group were 12, 9, 9, 2.Electron microscopic observation showed that there were more apoptotic bodies in the combined treatment group than those in the other groups, accompanied by mitochondrial edema.Conclusion NTP and X-ray irradiation therapy in the treatment of human hepatocellular carcinoma in nude mice model has a synergistic effect.Probably, it can be a new type of treatment in curing cancers.
3.Re-osseointegration of peri-implantitis affected and failed implants
STOMATOLOGY 2023;43(1):35-38
Peri-implantitis and implant failure are common issues in the implant dentistry. The contaminated implant can be treated with mechanical, chemical and assisted methods for the formation of re-osseointegration. Re-osseointegration is achievable with valid bone regeneration strategies. The survival rate of implant into the site of previous failure is lower than that of the initial implant. For the hopeless and failed implant, it is necessary to remove the implant with corresponding technique.
4.Mechanical test and two variable regression analysis of cavity design
Journal of Practical Stomatology 2000;0(06):-
Objective: To study the relationship between the depth and width of cavity design and to analyze the tendency of breaking load in preparations. Methods:Plaster models of mandibular first molar were prepared and magnified by 150%. Cavity on occlusal surface was designed and prepared in a cylinder shape with the depth(mm) of 3.0,4.5 and 6.0,and diameter(mm) of 3.0,4.5 and 6.0,respectively. 8 cavity samples were prepared for each design. The breaking load of the tooth models before and after restoration with self-curing resin was measured by Instron tester.Mechanical model static load test and two variable regression analysis were applied to study the mechanical property of the cavity design. Results:Before restoration, with the increase of depth and diameter, the incidence rate of tooth fracture increased. The width was the main factor. After restoration, the load was undertaken by restoration directly, and could be transfered to tooth and periodontal tissue through restoration uniformly. When the diameter of the cavity increased, the diameter of restoration also increased, and thus decreased the load on local structure of the tooth. With two-regression analysis, the regression equation and regression curve were obtained. Conclusion: The fracture of tooth before and after restoration is related to the diameter and depth of cavity design in cylinder shape. The regression equations of changing tendency of breaking load (Y) in preparation caused by the change of depth(X 1) and diameter(X 2) of cavity obtained by two-regression analysis are presented as follows: Before restoration: Y=1593.317-51.178 X 1-79.489X 2.After restoration:Y=1802.928 -192.461X 1+225.128X 2.

Knowledge management, as a new managerial concept, is the specific embodiment of knowledge based economy in the field of management while technological innovation, constituting the core of technological progress, is the effective extension and application of scientific and technological knowledge. Hospitals, which are knowledge based institutions, possess good foundations and advantages of implementing knowledge management and technological innovation. There is a close link between knowledge management and technological innovation in hospitals, the former being the basis and primary guarantee of the latter and the latter being the result and manifestation of the former. Hospital managers should take measures to promote the sound interaction between the two so as to enhance the core competency of their hospitals.

Chongqing Medicine 2014;(11):1281-1283
Objective To study the influence of splenectomy on the surgical efficacy in the patients with gastric cancer in the up-per and middle portion and entire stomach .Methods 86 patients with gastric cancer in the upper and middle portion and entire stomach receiving the gastric cancer D 2 radical operation in the two hospitals from April 2003 to January 2008 were selected and di-vided into the observation group(47 cases) and the control group(39 cases) .The observation group accepted the modified lymph-adenectomy with spleen-preserving ,while the control group accepted the D2 total radical gastrectomy with splenectomy .The long-term effects were compared between the two groups .Results The total hospitalization time and the occurrence rate of postoperative complications were(20 .62 ± 7 .93)d and 10 .64% in the observation group ,which were less than (27 .51 ± 12 .44)d and 30 .77% in the control group ,and the differences between the two groups showed the statistical significance (t=3 .128 ,χ2 =5 .446 ,P=0 .000) . The 5-year survival rate in different TNM stages had no statistical difference between the two groups (P>0 .05) .Conclusion For the patients with gastric cancer in the upper and middle portion and entire stomach without spleen or splenogastric ligament metas-tasis ,the modified spleen-preserving lymphadenectomy could make the patients to get the same prognosis as the gastrectomy com-bined with splenectomy ,which reduces the occurrence rate of complications and is worth promoting clinically.
