BACKGROUND: The occurrence of sexual and urinary dysfunction is higher in patients who have received rectal cancer surgeries. This could most likely be correlated with the age of the patients and the approach applied in the operation. Therefore, how to preserve the sexual and urinary functions has become a hot point in this field.OBJECTIVE: This study was designed to investigate the influence of differences in age and therapeutical approach on the sexual and urinary function in patients with rectal cancer.DESIGN: Investigation study on patients.SETTING: General Surgery Department, the 309 Clinical Division, General Hospital of Chinese PLA.PARTICIPANTS: Some male patients with rectal cancer hospitalized in the General Surgery Department, the 309 Clinical Division, General Hospital of Chinese PLA were involved from January 1999 to October 2000. All of the 79eligible patients had received a radical surgery for rectal cancer by the time of study. Their sexual and urinary function before surgery were normal and an over-2-year follow-up after surgery was conducted on each of them. The two groups, which were classified into two groups according to surgical ap-proaches they received, contained comparable quantity of sampling and age distributions, which prompts the validity of the comparison.METHODS: By distributing follow-up letters, outpatient inquiries and phone call investigations; the follow-up was conducted to evaluate the sexual functions in these patients, including their penile erection and ejaculation. The erectile function was assessed according to the International Index of Erectile Function Questionnaire-5 (IIEF-5). The assessment on ejaculation was based on whether the patients had a sexual climax and whether they can ejaculate. The definition of urinary function consisted of both short-term and long-term urinary functions.MAIN OUTCOME MEASURES: The sexual desire, erectile function, ejaculation and the urinary function in patients within different age brackets.RESULTS: After Miles operation, 81% patients developed sexual dysfunction, 46% got short-term urinary dysfunction(19/41) and 5 % (2/41) had long-term urinary dysfunction. While after Dixon operation, 55% patients had sexual dysfunction, 29% (11/38) had short-term urinary dysfunction, and none of the patients had long-term urinary dysfunction. The difference between the outcomes of the two operations was significant( P ＜ 0. 05) .Sexual dysfunction occurred at a rate of 38% in the less-than-40 age bracket, 60% in the 40-to-59 age bracket, and 96% in the over-60 age bracket. The overall differences between different pairs of age brackets were significantly ( P ＜ 0. 05 ).CONCLUSION: There is a high rate of postoperative sexual and urinary dysfunction in male population. The age of patients and the approach adopted in the surgery are directly correlated with the rate of dysfunction. An autonomic nerve-preserving radical operation for rectal cancer can reduce the occurrence of sexual and urinary dysfunction effectively.

Objective To analyze the clinical effect and treatment experience of breast conserving surgery.Methods The clinical data of one hundred and twenty-eight cases received breast conserving surgery in 309 Hospital of PLA from April 2006 to April 2011 was analyzed retrospectively.Results The follow-up rate was 95.3%(122/128) and the mean follow-up time was 54 months.The overall survival rate and disease-free survival rate at 5 years were 92.6% and 87.7% respectively.The local recurrence rate was 1.6%.Conclusion Breast conserving surgery is safe and effective for breast cancer treatment.Reasonable surgical indications,clean tumor margin and normative comprehensive treatment are critical for surgical effectiveness.

Objective To observe the analgesic effects of intradermal injection on the cervical-shoulder lesion areas caused by herpes zoster. Method The clinical data of 40 patients suffered from herpes zoster (distribution of skin lesion: C2~C4) were retrospective analyzed. All the cases were divided into two groups, the 20 patients in group A received routine therapies (administered by antiviral drugs, vitamins and calamine lotion) and 2ml 0.75% bupivacaine as well by intradermal injection. The other 20 patients in group B received routine therapy only. The curative effect was evaluated by visual analogue scale (VAS) and quality of sleep (QS). Results After treatment the scores of VAS and QS declined obviously in group A (P0.05). On the day of treatment the scores of VAS and QS in group A were much lower than in group B (P

Objective To evaluate the technique of treating severe tuberculous peritonitis complicated with intestinal obstruction. Method Clinical data covering 44 cases from Jan. 1994 to Dec. 2004 were analyzed retrospectively. All the 44 cases were suffering from severe tuberculous peritonitis complicated with intestinal obstruction for a long time. Among them 36 cases were diagnosed pre-operatively and 8 cases were confirmed post-operatively. All the patients underwent laparotomy, and all intestinal adhesions were divided, then the intestine loops were regularly aligned. Result 43 cases were cured, 2 patients developed postoperative intestinal fistula, and one patient died. Conclusion No curative effect could be obtained if medical treatment only was given for tuberculous peritonitis complicated with complete intestinal obstruction. The present surgical technique offers a better chance to relieve intestinal obstruction as a reult of tuberculous peritonitis.

Objective To investigate the effect of preoperative regional intra-arterial chemotherapy on apoptosis and apoptosis-regulating genes in advanced breast cancer.Methods 56 patients were divided into 2 groups:Preoperative regional intra-arterial chemotherapy group(treatment group,28 cases)and non-preoperative chemotherapy group(control group,28 cases).Apoptotic cells were examined by TUNEL and bcl-2 expression,and bax was detected by immunohistochemical techniques.Results Apoptotic index(AI)of breast cancer in the treatment group was 8.74%,while that of the control group was 4.65%.The bcl-2 expression in treatment group was 0.68?0.06,while in control group was 2.24?0.36.Expression of bax in treatment group was 0.72?0.06,while in control group was 0.38?0.04(P

Through the qualitative study of peritoneal cavity free cancer cells of patients with gastric cancer, to evaluate the rational of exercising intraoperative no touch isolation technique, routine peritoneal and warm perfusion chemotherapy after the operation. 102 patients in PLA 309 Hospital with gastric cancer were included into the study. 100 ml peritoneal fluid were collected respectively before the investigation and before close peritoneal cavity,and rapidly sent for free cancer cells examination. Results: Before the investigation, the positive rate of free cancer cells is 36.3%, and the positive rate before close peritoneal cavity is 52.9%. The free cancer cells positive rate is concerned with tumor infiltration depth, serous membrane infection area and the type of the histopathology。Conclusions: Inside the peritoneal cavity of patients with gastric cancer, free cancer cells are able to survive and have a high degree of activity. Although all kinds of intraoperative no touch isolation technique are used, it still cannot be avoided that some cancer cells will exfoliate and slip into the peritoneal cavity. The wound stimulation during the operation will certainly increase the exfoliation. So, it is quite necessary in the course of operation to adopt no touch isolation technique and to use a great deal of normal saline to give peritoneal cavity lavage. And what's more important is, to give these patients who show positive in the free cancer cell examination perfusion chemotherapy after the operation.

To evaluate the effect of local resection plus axillary dissection in the treatment of early breast cancer, 112 cases of early breast cancer were divided into 2 groups: quadrant resection plus axillary dissection group(66 cases) and Halsted′s method group(46 cases).Their survival rate, local recurrence rate, metastasis rate,cosmetic effect of breast were observed for a prolonged period. The results showed that the 3,5,8 year survival rates in the first group were respectively 97 0%,87 9% and 71 2%. The 3,5,8 year survival rates in the second group were respectively 97 8%,80 5%,76 1%. The rate of local recurrence was 6 1% in the first group and 4 3% in the second group.The metastasis rate of the first group was 16 7%,and that of the second group was 21 6%.In 83 8% of patients in the first group,the breasts retained a satisfactory cosmetic form.It suggested that similar to the Halsted's method,the quadrant resection plus axillary dissection method is an ideal method to treat early breast cancer.

To evaluate the effect of intra arterial infusion chemotherapeutic medicine and immunizator in treatment of later gastro intestinal carcinoma, 86 cases suffering from irremovable gastro intestinal carcinoma were divided into treatment group(group A) and control group (group B). 46 cases in group A were treated with intra arterial chemo immunotherapy, 40 cases in group B were treated only with chemotherapy. Effective rates of group A and group B were 82 6% and 52 5% ( P

To study the treatment of peritoneal and hepatic recurrence of advanced gastric carcinoma after operation, 218 patients were divided into treatment group and control group.Treatment group: (hyperthemic peritoneal perfusion and intraarterial infusion chemotherapy)126 cases. Control group (peripleral veins): 92 cases. The peritoneal and hepatic recurrence and 3 year survival rate of each group were analyzed. The peritoneal and hepatic recurrence and 3 year survival rate in treatment group were 27%, 12 7% and 69 5%. and were 44 5%, 26 1% and 47 8% in control group. Hyperthermic peritoneal perfusion and intraarterial infusion chemotherapy are effective in control of the recurrence of advanced gastric cancer after operatin.
