Objective To observe the effects of recombinant human epidermal growth factor ( rhEGF)on wound healing of perianal abscess after operation. Methods A total of 112 cases of perianal abscess after operation were randomly divided into the study group( n=56 )and control group( n=56 ). Patients in the control group were disinfected routinely and treated by metronidazole or rivanol. In the stud-y group,patients were treated by rhEGF after disinfection of saline. Wound edema score was evaluated at the 3rd,7th and 10th day after the surgery. Healing time of the wound was recorded simultaneously. Re-sults Wound edema scores in the study group[(1. 20 ± 0. 70),(1. 00 ± 0. 67),and(1. 05 ± 0. 69)] were significantly lower than those of the control group[(1. 70 ± 0. 66),(1. 90 ± 0. 74),and(1. 70 ± 0. 73)]at the 3rd,7th and 10th day after operation(P﹤0. 05). Conclusion rhEGF can promote wound healing obviously.

Objective To investigate the clinical effect of modified seton therapy with counterparts drainage on high anal fistula.Methods One hundred and forty-four patients with high anal fistula were randomly assigned to the observed group (modified seton therapy with counterparts drainage,74 cases) and the control group (the traditional high hanging line therapy,70 cases).The clinical efficacy,visual analogue scale (VAS),Wexner incontinence score,fecal incontinence quality of life index (FIQLI) score were compared.Results Observed group were cured with 40 cases,improved with 27 cases,ineffective with 7 cases,control group were cured with 25 cases,improved with 43 cases,ineffective with 2 cases,difference between two groups was statistically significant (P ＜ 0.01).The healing time in observed group was significantly shorter than that in control group(P＜ 0.01).The VAS after therapy 1,7 d in observed group was significantly lower than that in control group (P ＜ 0.05).The Wexner incontinence score,FIQLI score before therapy was no significant difference between two groups (P ＞0.05).The Wexner incontinence score,FIQLI-lifestyle score,FIQLI-depression/self-perception score,FIQLI-distress score after therapy 3 months in observed group was significantly higher than that before therapy and control group after therapy 3 months (P ＜ 0.05),there was no significant difference Wexner incontinence score and FIQLI score before therapy compared with therapy 3 months in control group (P ＞ 0.05).Conclusions Modified seton therapy with counterparts drainage may be a valid treatment for high anal fistula.The successful outcome is associated with significant improvement in quality of life.

Objective To observe the effect of saline gauze tamponade of calculus bovis sativus on the level of IL-6 and IL-8 in the tissue of patients with perianal abscess after operation,and to explore its possible mechanism of action in promoting wound healing.Methods Patients with 84 cases of anal abscess surgery,were randomly divided into treatment group(n=42)and control group(n=42).Treatment group calculus bovis sativus research pressed into powder,take 0.10~0.15g evenly scattered in the saline gauze on the wound packing,the control group was treated with physiological saline gauze wound.After treatment,3,7 and 10d were treated with local granulation tissue about 0.2cm×0.2cm×0.1cm size,the IL-6 and IL-8 cytokines in local tissues were detected by enzyme-linked immunosorbent assay.Results There was no significant difference in the expression of IL-6 and IL-8 between the two groups 3 days after treatment(P>0.05),IL-6 and IL-8 in the treatment group(7,10d)were significantly lower than that in control group,and the difference was statistically significant(P<0.05).Conclusion Calculus bovis sativus in the treatment group,IL-6 and IL-8 levels were significantly lower than those of the control group,indicating that calculus bovis sativus can reduce local inflammation response,promote healing of wound after perianal abscess operation.

Objective To discuss the relationship between the substype of peripheral blood CD8 lymphocyte in patients with chronic hepatitis virus B and clinic condition and the replication of HBV. Methods CD45RO, CD45RA and CD28 of peripheral blood CD8 lymphocyte were detected by flow cytometry with multicolor fluorescence technology in 107 patients with chronic hepatitis virus B and 20 healthy volunteers. Results The total quantity of CD8 lymphocyte in patientswith chronic hepatitis virus B was not different from that in controls. The percent of CD3+ CD8+/CD45R0+ cells in patients with chronic active hepatitis was significantly higher than that of the control (15.7?3. 35)% vs( 8. 56?1. 12)% , P

Objective To investigate the variation characteristics of adenovirus type 55 (HAdV-B55) gene on plateaus.Methods Throat swabs were collected from HAdV-B55 infected patients and used for virus isolation in HEp-2 cells.The whole-genome sequence was obtained by PCR and sequencing.HAdV-B55 gene sequence was blast with the previously reported virus.Results HAdV-B55 strains were isolated from throat swabs, which were named LS89/Tibet/2016.The whole-genome sequence was obtained and submitted to GenBank with the accession number of KY002683.No large fragment gene recombination was found between this HAdV-B55 strain and previous strains, and the sequence similarity with QS-DLL strain was 99.9%.Conclusion This study provides more information for the evolution patterns of adenovirus 55 and will contribute to the prevention and control of HAdV-B55 infection in the future.

Chronic Urticaria(CU)is a common skin disease involving autoimmunity and allergies,which brings a heavy burden to patients and society.The theory of traditional Chinese medicine"the Lung is combined with the Large Intestine,and the symptoms of large intestine can be reflected from the skin"has long shown that there is a close physiological and pathological relationship between the function of the Large Intestine and the skin.With the modern advancement of the"gut-skin axis"theory,the correlation between gut microbiome and CU has gradually become an emerging focus of research.Adjusting the imbalance of gut microbiome would be a new trend in the clinical treatment of CU.Acupuncture has a beneficial effect of regulating the gut microbiome,and the definite curative effect on CU.Therefore,this article summarized the research progress between the gut microbiome and CU in recent years,in order to discuss the feasibility of acupuncture to treat CU by regulating the gut microbiome,and provide a new idea for the mechanism research of acupuncture in the treatment of CU from the perspective of"treating skin from intestine".

ObjectiveTo summarize the modeling methods, test indicators, and evaluation methods of the animal models of urticaria and provide a basis for the subsequent research on urticaria models. MethodWith the keywords of "urticaria" and "animal model" and the time interval from inception to July 13, 2022, relevant articles were retrieved from CNKI, Wanfang Data, VIP, CBM, Web of Science, Embase, and PubMed. Two evaluators independently screened the articles and extracted the publishing time, sources, animal conditions, modeling methods, modeling time, and test indicators from the articles meeting the inclusion criteria to establish a data library for quantitative statistics and analysis. ResultA total of 116 articles were included, involving 129 animal experiments (102 in Chinese and 27 in English) of urticaria. In the last three years, the studies about the animal models of urticaria presented an obvious upward trend, and the articles were dominated by dissertations. KM mice and SD rats of both females and males were mainly used for the modeling of urticaria, and the models were mainly established by passive sensitization of skin for 14-16 days. The models were mainly evaluated based on apparent indicators such as blue-stained lesion area and ear swelling, supplemented by the pathological indicators of the skin and serum. ConclusionAlthough the experimental studies of urticaria are increasing, the modeling methods lack unified modeling standards and have low coincidence with clinical symptoms. Therefore, this paper analyzed the modeling elements and evaluation criteria of urticaria animal models, and proposed that both male and female KM mice (6-8 weeks old) or SD rats (8-10 weeks old) of SPF grade should be preferentially selected for modeling. Active and passive sensitization can be combined for the modeling, and the specific modeling elements such as modeling time and sensitization times need to be further explored. The model evaluation should include four aspects of behavior, appearance, pathology, and immunity.
