A total of 120 patients with Ⅲ/Ⅳ degree hemorrhoids were randomly divided into 3 groups.Self-made drainage(A group),traditional device(B group)and stuffing(C group) were used at the end of operation.The patient postoperative complications and satisfaction were observed and compared.The results showed that postoperative abdominal distension,pain,medical dressing dampness and satisfaction were better in A group than those in B and C groups(all P ＜0.01).Postoperative abdominal distention in B group was lighter than that in C group and medical dressing dampness less in C group than that in B group (all P ＜ 0.01).Thus the self-made drainage device may reduce the levels of postoperative abdominal distension,pain and medical dressing dampness and increase postoperative patient satisfaction.

Objective To observe the changes of serum potassium concentration in rectal cancer patients from the admission to before the operation,to provide clinical evidence for preventing serum potassium disorder during and after their operation.Methods Monitoring of the changes of serum potassium concentration of 40 cases of rectal cancer patients according to three time points including the first day of admission,before taking of cathartics and the morning before operation.They were divided into different groups according to their age(young,middle age and elderly group),gender(male and female group),diet(normal,decreased slightly and serious decline group) and course(long,middle and short course group) of disease.The serum potassium concentration was observed between each time point of each group and SPSS13.0 statistical software was used to analyze the changes above.Results The mean of all patients' serum potassium concentration was (4.09 ± 0.62) mmol/L on the first day of admission,was (3.83 ± 0.46) mmoL/L before taking of cathartics that was decreased compared to the former and there was significant difference (P ＜ 0.01),it was (3.36 ±0.40) mmol/L on the morning of operation and had significant difference with the above two groups (P ＜ 0.01).It hadn't significant difference between different gender and age groups at different time points (P ＞ 0.05) except between the young group and the elderly group in the morning of the operation (P ＜ 0.05).There were statistically significant differences between the different diet condition and different course at anytime point (P ＜ 0.01).Conclusions The rectal cancer patients were possiblely in hypokalemia before operation,the causes might be relative to the long course of disease,the decreased diet,the aged and infirm,the diet structure change after admission and taking cathartics cleaning intestinal tract.

Objective In order to provide clinical evidence of reducing postoperative complications of procedure for prolapse and hemorrhoids and observe the effects of constipation on postoperative complications of procedure for prolapse and hemorrhoids.Methods One hundred and sixty cases of hemorrhoid were divided into two groups according to whether suffering from constipation:there were eihgty cases who were suffered from constipation in the experimental group and eighty cases who were not suffered from constipation in the control group.All patients' postoperative bleeding,anal edema,stool impaction and satisfaction were observed within 30 days and these data were compared and analysed by using SPSS 13.0 software.Results In the experimental group,the postoperative bleeding incidence was 37.5 ％ (30/80),the anal edema incidence was 31.3 ％ (25/80),the stool impaction inci dence was 8.6％ (7/80),and the patients' satisfaction rate was 88.6％ (71/80).In the control group,the postoperative bleeding incidence was 18.6％ (15/80),the anal edema's incidence was 15.0％ (12/80),the stool impaction incidence was 1.3％ (1/80),and the patients' satisfaction rate was 97.5％ (78/80).All the indexes above were different statistically in the two groups (P ＜ 0.05).Conclusion constipation could increase complications and reduce the degree of satisfaction after procedure for prolapse and hemorrhoids.

Objective To observe the clinical effect of thrombus removal of external hemorrhoid combined with procedure for prolapse and hemorrhoids(PPH) in the treatment of circumferential mixed hemorrhoid with incarceration.Methods A total of 118 cases of circumferential mixed hemorrhoid with incarceration were divided into two groups:experimental group of 60 cases was treated by thrombus removal combined with PPH;control group of 58 cases was treated by Milligan-Morgan.We observed the differences of postoperative visual analogue scale (VAS)score,edema,bleeding,residual skin tag,wound healing time,anal stenosis,fecal incontinence,anorectal manometry and satisfaction in the two groups.Results There was significant difference between the experimental group and the control group in postoperative edema,bleeding and residual skin tag(χ2=6.63,4.19,6.64,P<0.05),but postoperative anal stenosis and fecal incontinence weren′t statistically significant different(χ2=0.38,1.11,P>0.05).Postoperative VAS score,wound healing time,satisfaction,anal resting and anal maximal squeeze pressure between the two groups were all statistically different(P<0.01).Conclusion The operation of thrombus removal of external hemorrhoid combined with PPH can effectively reduce the postoperative complications and promote recovery.

Objective To observe the Lactulose Oral Solution's influence in PPH postoperative complications and patients′ satisfactory rate for constipation and to find more intervention measures for reducing the complications. Methods A hundred and twenty cases of hemorrhoids with constipation were randomly divided into the two groups: the experimental group, the control group in 60 cases in each group. All patients’ postoperative bleeding, anal edema, stool impaction and satisfaction were observed and compared within 30 days. Results In the control group, the postoperative bleeding’ cases were of 23, anal edema’s were of 20 and stool impaction‘s were of 8. The incidence was 38.3%, 33.3% and 13.3% severally. The satisfactory patients were of 49 and the degree of satisfaction was of 81.7%. In the experimental group, the postoperative bleeding’ cases were of 12, anal edema’s were of 8 and stool impaction's was of 1. The incidence was 20%, 13.3% and 1.7% respectively. The cases who were satisfactory were of 58 and the degree of satisfaction was 96.7%. The postoperative bleeding , anal edema , stool impaction and satisfaction were different statistically in the two groups above (P < 0.05). Conclusion It can reduce PPH postoperative complications and increase patients′satisfaction by using Lactulose Oral Solution in patients with constipation and it will have a certain clinical value if these patients take this oral solution routinely.

We isolated three secondary metabolites by silica gel column chromatography from endophytic fungus 12.3.2 that was isolated from Taxus yunnanensis and could produce taxanes. They were identified as cembrene (3,7,11-trimethyl-14-(1-methylethyl)-1,3,6,10-cyclotetradecatetraene), diisooctyl phthalate (1,2-benzenedicarboxylic acid diisooctylester) and ethyl oleate (9-octadecenoic acid-ethyl ester) by infrared spectra (IR), mass spectra (MS) and 1H-nuclear magnetic resonance (NMR). Their antibacterial activities against Staphylococcus aureus, Bacillus subtilis, Escherichia coli, Pseudomonas aeruginosa and Candida albicans were examined. Results show that all of the three compounds could inhibit the growth of those pathogenic bacteria. Especially, cembrene showed stronger inhibition to S. aureus, B. subtilis and C. albicans. This is the first report on cembrene produced by plant endophytic fungus.
