Objective To compare effects of laparoscopic versus open anterior resection of rectal carcinoma on immune functions.Methods A total of 38 patients were given either laparoscopic(18 patients) or open(20 patients) anterior resection of rectal carcinoma from April 2004 to June 2005 in this department.The percentages of T-lymphocytes(CD_3,CD_4,and CD_8) and natural killer cells were calculated by using the flowcytometry.The levels of immunoglobins(IgG,IgA,and IgM) and complements(C_3 and C_4) were detected by using the immunonephelometry.Results In levels of T-lymphocytes,immunoglobins,and complements,there were no statistically significant differences between open and laparoscopic groups 24 and 96 hours after operation.In levels of natural killer cells,no differences were observed in laparoscopic group before and after operation(24 and 96 postoperative hours) while a significant decrease were found in open group after operation.Conclusions As compared with open surgery,laparoscopic anterior resection of rectal carcinoma has less influence on natural killer cells.

Objective To investigate the safety and feasibility of laparoscopic total/subtotal proctocolectomy. Methods Laparoscopic total/subtotal proctocolectomy was performed in 8 cases from March 2003 to November 2005, including 1 case of multiple colorectal tumors, 3 cases of ulcerative colitis, 2 cases of familial adenomatous polyposis, and 2 cases of slow transit constipation. The operation included ileal pouch-anal canal anastomosis in 3 cases, ileal pouch-rectum anastomosis in 3 cases, and cecum-rectum anastomsis in 2 cases. A prophylactic ileostomy was conducted in 5 cases. Results The operation was laparoscopically conducted in all the 8 cases, without conversions to open surgery. No fatal case was encountered. The operative time was 5.5~7.5 h (median, 6 h). The intraoperative blood loss was 150~400 ml (median, 200 ml). There was no intra- or post-operative blood transfusion. The patients began to take diet at 48 h postoperatively. Follow-up observations in 8 cases for 4~31 months (median, 25 months) showed 1 case of intraabdominal infection and 1 case of anastomsis stenosis. Conclusions Laparoscopic total/subtotal proctocolectomy is safe and feasible.

Modern medicine makes it possible to turn those former impossible ideas into reality.Meanwhile,more and more social and ethical issues are also drawing public attention arising from the development of modern medicine.This paper explores reasonable and feasible countermeasures to cope with the ethical issues brought by modern medical development from a cultural perspective.

20?10 6/L were observed in the blood. No patients presented bone pain, fever, abnormal function of liver and kidney, and so on. Conclusions:Our results indicated that rhG-CSF is efficacious and safe in auto-PBSCT for patients with plasma cell diseases. Therefore, the expense of hospitalization would be reduced significantly.

Objective To observe clinical efficacy of laparoscopy combined with gonadotropin-releasing hormone agonist (GnRH-a ) in the treatment of endometriosis (EMs).Methods 158 patients who underwent laparoscopic surgery and were diagnosed endometriosis in our hospital during Sep.2010 to Dec.2010 were chosen and divided into three groups:control group were treated with pure laparoscopic surgery,group A were treated with laparoscopic surgery and follow-up GnRH-a medication,and group B were treated with laparoscopic surgery,follow-up GnTH-a medication and add-back therapy.The total effective rates,recurrence rates,the changes of hormone levels before and after the treatment and adverse reaction rates after treatment were compared and analyzed to evaluate the efficacy of different treatments.Results The total effective rates of group A and group B (84.6%,86.2%) were significantly higher than that of control group (58.3%),and the difference was statistically significant (P=0.032,P=0.032).The recurrence rates of group A and group B (15.4%,13.8%)were significantly reduced compared with that of control group (41.6%)(P=0.012,P=0.012).The hormone levels decreased dramatically after treatment in three groups.The adverse reaction rate of group B was apparently reduced compared with that of group A,and the difference was statistically significant (P=0.001 ).Conclusion Laparoscopy combined with GnRH-a medication was a safe and effective treatment for endometriosis.The application of GnRH-a after laparoscopy can significantly increase the total effective rate of the operation and reduce the postoperative recurrence rate.For the patients who need to take long-term GnRH-a treatment,add-back therapy need to be given to decrease its adverse reaction and recurrence rate,or to delay its recurrence,thus could improve patients' living qualities significantly.

0.05).Conclusions Laparoscopic resection of colorectal carcinoma is feasible and safe for elderly patients.The method can reduce the rate of postoperative complications.

Objective To study the feasibility of laparoscopic radical gastrectomy.Methods From August 2006 to May 2007,31 patients with gastric cancer received laparoscopic radical gastrectomy(radical distal gastrectomy in 26 cases and radical total gastrectomy in 5).Results Among the cases,1 was converted to an open surgery,2 were treated completely by laparoscopic radical gastrectomy;and in the other 28 cases,the radical gastrectomy was performed under the assistance of laparoscopy.Lymph node dissection of D1+? was performed on 2 patients and D2/D2+ was adopted in the other 29.One case was done in combination with partial liver dissection.The median operative time was 5 h(range 4.5-7 h).The median blood loss was 150 ml(range,100-600 ml).One patient received blood transfusion during the operation.Intraoperative spleen injury occurred in one case.The median number of harvested lymph nodes was 20(range,14-33).No patient died after the surgery.The median time for gastrointestinal function recovery was 4 d(range 3-6 d).One patient developed gastroparalysis after the operation and was cured by conservative therapy.One of the patients had bleeding of the jejunal pouch after total gastrectomy.And one showed subluxation of the articulatio cricothyroideus.No anastomotic leakage and lung infection occurred after the surgery.And no recurrence or metastasis was found during a 2-to 8-month follow-up(median,5).Conclusion Laparoscopic radical gastrectomy is feasible and safe.

Objective To study the safety of laparoscopic total mesorectal excision for middle and lower rectal cancer.Methods A retrospective comparison was made between 52 cases of open total mesorectal excision from December 2002 to December 2005(Open Group) and 49 cases of laparoscopic mesorectal excision from January 2003 to June 2006(Laparoscopic Group).Results There was no difference in baseline parameters between the two groups.As compared with the Open Group,the Laparoscopic Group presented less blood loss [for anterior resection: 160?106 ml(n=37) vs 298?186 ml(n=36),t=-3.908,P=0.000;for abdominoperineal resection: 180?153 ml(n=10) vs 356?170 ml(n=14),t=-2.604,P=0.016].The recovery time of bowel functions was shorter in the Laparoscopic Group than in the Open Group(2.4?1.8 d vs 3.6?1.5 d;t=-3.648,P=0.000).The overall complication rate in the Laparoscopic Group(14.3%,7/49) was lower than that in the Open Group(44.2%,23/52)(?2=10.834,P=0.001).No significant difference was seen between the two groups in the number of lymph node resected(12.7?6.5 vs 13.6?7.0;t=-0.668,P=0.505),with negative margins in both groups.Follow-up observations were carried out in 45 cases in the Laparoscopic Group(91.8%) for 2～42 months and in 47 cases in the Open Group(90.4%) for 6～42 months,respectively.The local recurrence rate was respectively 4.4% in the Laparoscopic Group(2/45) and 4.3% in the Open Group(2/47). Conclusions Laparoscopic total mesorectal excision for middle and lower rectal cancer is safe and feasible.

Objective NAC therapy was used to observe the effect of TNF-?,hs-CRP,PaO2,PaCO2and lung function in patients with COPD,so as to evaluate the therapeutic effect. Methods 65 patients with COPD were recruited and the patients were randomly divided into 2 treatment groups:control group (n=31) and experimental group (n=34). Patients in the two groups received the conventional treatment of COPD in unchanged dosage for the duration of the study except stopping using antibotic drug after infection was resolved. NAC tablets were taken orally at a dose of 600mg once a day in experimental group. After 8 weeks treatment,we appraised lung function and the plasma level of TNF-?,hs-CRP,PaO2 and PaCO2. Results Compared with normal controls,the plasma levels of TNF-? and hs-CRP increased significantly. The higher level of those ,the higher lung function class was in 65 COPD patients,and there was significant effect(P
