Objective To observe the clinical efficacy of procedure for prolapse and hemorrhoids ( PPH) for treatment of rectal mucosa prolapse.Methods The 100 patients who suffered from rectal mucosa prolapse and were planning to take surgical treatment for the first time in our hospital from June 2013 to June 2015 were randomly divided into the treatment group and the control group .Patients in the treatment group(n=50) underwent PPH while patients in the control group (n=50) underwent traditional simplified mucosal plication technique .To observe the therapeutic effect of the two groups ,the average operation time ,average length of stay in hospital ,postoperative pain within 72 hours,postoperative anal function and postoperative complications of the two groups .Results There was no significant difference in the over-all treatment effect between the two groups(P>0.05).The average operation time, average length of stay in hospital,postoperative pain with-in 72 hours and postoperative anal function of the treatment group were lower than those of the control group ,and the differences were significant (P<0.05).Bleeding and anal bearing-down occurred much less in the treatment group compared with the control group ,and the differences were statistically significant(P<0.05).But there was no significant difference in postoperative complications such as recurrence ,rectal steno-sis and anal incontinence (P>0.05).Conclusion Compare to the traditional simplified mucosal plication technique ,PPH technique has more advantages such as shorter operation time ,less anguish of patients,less complication,shorter hospitalization time,and higher security, which indicates PPH could become the preferred method for treatment of rectal mucosa prolapse .

Objective To explore the difference of the curative effect between incision-thread-drawing procedure and traditional incision drainage in the treatment of perianal abscess.Methods A total of 150 patients diagnosed with perianal abscess and treated at the first time from June 2015 to June 2016 in our department were selected as the research object in this experiment,who were divided into the observation group(75 cases) and control group(75 cases) according to the surgical method.Patients in the observation group were performed with incision-thread-drawing procedure,while the control group were treated by traditional incision drainage.The overall treatment effect,operation time,postoperative recovery time,hospital stay,hospital costs,wound healing time and postoperative complications between the two groups were observed and compared.Results The difference of the overall treatment effects between two groups were not statistically significant(P>0.05).The operation time,the postoperative recovery time,the hospitalization time and the cost,the time of wound healing of observation group were significantly better than the ones of the control group,the differences were statistically significant(P<0.05).The recurrence rates of anal fistula,abscess and other complications in patients of observation group were significantly lower than the ones of control group.The differences were statistically significant(P<0.05).Conclusion Compared with traditional incision drainage,the incision-thread-drawing procedure is more effective with less complications and lower recurrence rate,which should be the first choice for the treatment of perianal abscess.

AIM: To study the effects of angiotensin converting enzyme inhibitor(ACEI) on elastase after balloon injury. METHODS: The carotid arteries and aortas twelve-weeks-old Wistar male rats were injured by balloon catheter. The rats were divided into experimental and control groups in which ACEI (temocapril-HCl,10 mg?kg -1 ?d -1 ) and the vehicle were administered 2 days before injury respectively and the animals were sacrificed on day 2, 3, 5 and 10, respectively. In situ hybridization, immunohistochemistry and elastase activity bioassay were used for studying elastase . RESULTS: The intimal area on day 10 in the experimental group was significantly suppressed compared to that in the control rats( P

Objective To investigate the clinical safety of preoperative lymphatic chemotherapy in the treatment of reetal cancer.Methods The regional and systemic symptoms,postoperatwe stoma healing,haematogenesis.functions of hean,liver and kidney after lymphatic chemotherapy,and the level of CD3+,CD4+,CD8+,CD4+/CD8+,CD(16+56)+in blood 30 minutes before and 48 hours after lymphatic chemotherapv were detected.Results There were no significant effects of lymphatic chemotherapy on the regional and systemic symptoms,postoperative stoma healing,haematogenesis and the functions of heart,liver and kidney.The level of CD4+/CD8+48 hours after lymphatic chemotherapy was significantly increased(t=7.145,P＜0.05),while no significant changes of CD3+,CIM+,CD8+,CD(16+56)+were detected(t=1.782,1.151,1.184,0.955,P＞0.05),when compared with those 30 minutes before lymphatic chemotherapy.Conclusions Preoperative lymphatic chemotherapy is safe and can enhance patients'immunity in early stage.

Objective To compare the treatment effects between lymphatic chemotherapy and regional extended release chemotherapy (RERC) for rectal cancer lymph node metastasis. Methods The lymph nodes at or beside colon (first station), beside (second station) and at the root of mesentery blood vessel (third station) of the patients with rectal cancer in control group (20 cases), lymphatic chemotherapy group (20 cases) and RERC group (20 cases) were removed to compare proliferation index (PI), apoptotic index (AI) and AL/PI of cancer cells in the lymph nodes. Results The PI, AI, and AI/PI of cancer cells in correspondent lymph nodes were not statistically different between lymphatic chemotherapy group and the other 2 groups (F=4.973-7.394, 5.372-8.694, 4.527-5.436, P<0.05; t=3.128-7.688, 3.388-9.615, 6.518-13.180, P<0.05). The PI, AI, and AI/PI of cancer cells in the first and second station lymph nodes in RERC group were significantly different from those in control group (t=5.103, 4.927; 6.938, 6.450; 8.839, 9.021; P<0.05), and from those in the third station lymph nodes in RERC group (F=6.572, 8.964, 5.845, P<0.05; t=3.505, 3.353; 5.397, 4.701; 9.039, 8.629; P<0.05). Sorted by the treatment effects for cancer cells in lymph nodes, the first is each station of the lymphatic chemotherapy group, followed by the first and second station of the RERC group, and then the third station of the RERC group which was almost equal to any station of the control group. Conclusion Lymphatic chemotherapy is better than RERC in the treatment of rectal lymph node metastasis in the aspect of scale and degree.
