ABSTRACT
Objective To compare the clinical effect of surgery with longitudinal incision and transverse suture in the treatment of anal fissure excision of anal fissure.Methods 60 patients with anal fissure who required surgery were selected,and they were randomly divided into two groups according to the digital table.30 patients in the control group received anal fissure resection,30 cases in the observation group received anal fissure longitudinal incision and transverse suture treatment.The clinical curative effect was compared between the two groups.Results The effective rate of the control group was 93.33％,which of the observation group was 96.67％,there was no significant difference between the two groups (P ＞ 0.05).The postoperative pain score of the control group was (3.89 ±1.30) points,which of the observation group was (1.33 ± 1.20) points,there was significant difference between the two groups(t =8.449,P＜ 0.05).The incidence rate of complication of the control group was 6.67％,which of the observation group was 23.33％,there was significant difference between the two groups (x2 =9.524,P ＜ 0.05).Conclusion The surgical treatment of anal fissure,surgery and excision of anal fissure anal fissure joints have advantages and disadvantages according to the treatment of transverse slitting,the specific patient should select the specific surgical methods.
ABSTRACT
Objective To design experimental conditions of Riboflavin combining with ultraviolet light illumination for pathogen inactivation and to verify its effect.Methods The effects of multi-factors,such as Riboflavin concentrates,dosage of ultraviolet irradiation,pH value and medium,were observed on E.coli inactivation by photochemical method when it was used as an indicating germ in phosphorus solution(PBS)and taken count by smearing Mac-lonkey agar plates for colony-forming units.Results The reduction of E.coli reached 3.87 logs when the system was treated with 12.5 umol/L riboflavin and 3.0mJ/ml of ultraviolet light at 254nm in PBS medium.Conclusion E.coli in PBS medium was sensitized to low concentrates of Riboflavin and low dosage of ultraviolet irradiation.
