Objective To sort out the clinical research evidence on the promotion of wound healing after anal fistula surgery by traditional Chinese medicine in the past decade,and understand the evidence distribution in this field,the evidence map system was used.Methods Computer retrieval of CNKI,VIP,Wanfang,PubMed,Web of Science,EMbase,The Cochrane Library and other databases were searched.Interventional studies,observational studies,systematic review/meta-analysis on the treatment of postoperative anal fistula wounds by traditional Chinese medicine in the past decade were included.The evidence was analyzed and presented in the form of text and graphics.And the quality of clinical RCT was evaluated using Cochrane systematic review manual.AMSTAR was used to evaluate the quality of meta-analysis,and the JBI quality evaluation tool was used to evaluate the methodological quality of retrospective studies.Results A total of 544 articles were included.In recent 10 years,the number of published documents showed an increasing trend.The intervention measures of TCM to promote wound healing after anal fistula operation included single intervention mode and combined intervention mode.The outcome indexes mainly included clinical efficacy,basic wound condition,TCM syndrome score,adverse reactions,quality of life,long-term efficacy and so on.The overall quality of clinical RCT,retrospective analysis and systematic review/meta-analysis is low.Most studies showed that Chinese medicine had advantages in the treatment of vertigo,and more high-quality studies were still lacking.Conclusion More large-sample,multi-center RCTS should be carried out in the future,and the quality of relevant systematic review/meta-analysis should be improved.The advantages of TCM in promoting wound-heal after anal fistula surgery can be fully explored,which provide strong support for the effectiveness and safety of traditional Chinese medicine in improving wound management.

Objective To investigate the expression of T cell subsets in the spleen of BTBR T+Itpr3tf autistic mouse at 4,8,and 12 weeks of age,and to determine the optimal age for studying the relationship between immune abnormalities and autism in BTBR autistic mice.Methods It randomly selected 5～6 male BTBR mouse at 4 weeks,8 weeks,and 12 weeks of age and C57BL/6J mouse of the same gender at corresponding ages for the three-box social interaction test,the self-grooming test,and the marble-burying test;Single cell suspensions were prepared from the spleens of mouse at 8 and 12 weeks of age,and flow cytometry was used to detect 8 subsets of T cells(TH 1,TH2,TH17,TC1,TC2,TC17,TFH,and Treg).Results Compared with C57BL/6J mouse of the same age,BTBR mouse at 4 weeks,8 weeks,and 12 weeks of age showed a decrease in social time(P＜0.001),an increase in grooming time(P＜0.01,P＜0.001),and an increase in the number of marbles buried(P＜0.01,P＜0.001)in BTBR mouse at 8 weeks and 12 weeks of age.As well,the expression of TH 1(P＜0.001),TH2(P＜0.01),TC 1(P＜0.05),TC2(P＜0.001),and TFH(P＜0.01)cells in 8-week-old BTBR mouse were significantly increased,while the expression of Treg(P＜0.001)cells were significantly decreased;The expression of TH 1(P＜0.01),TH2(P＜0.01),TH 17(P＜0.05),TC1(P＜0.01),TC2(P＜0.001),TC 17(P＜0.01),and TFH(P＜0.001)increased in 12-week-old BTBR mouse,while the expression of Treg(P＜0.05)cells decreased.At different age stages(P＜0.050)the ratio of TH 1/Treg and TC 1/Treg in 8-week-old BTBR mouse were significantly higher than those in 12 week old mouse,while the TC 17/Treg ratio decreased.Conclusions BTBR mouse at different developmental stages exhibit varying degrees of abnormal increase in Teff/Treg ratio.Based on result of behavioral test,it is recommended to use 8-week-old BTBR mice for research on autism and immune abnormalities.

Objective:To investigate the correlation between three-dimensional (3D) true acetabular cup coverage and two-dimensional (2D) X-ray acetabular cup coverage in total hip arthroplasty (THA) and identify effective parameters for evaluating acetabular cup coverage.Methods:Sixteen pelvic models were 3D-printed from CT reconstruction data of healthy adult pelvises. Postoperative acetabular models were prepared using standard THA procedures. The postoperative models were centered on the acetabulum and positioned under a C-arm fluoroscope. Fluoroscopy was conducted by rotating the C-arm at different angles (15°, 30°, and 45°) to obtain anteroposterior (AP) and iliac oblique X-ray images of the hip joint. The 2D acetabular coverage at different fluoroscopic angles (AP, 15° iliac oblique, 30° iliac oblique, and 45° iliac oblique) was recorded and compared with the 3D acetabular coverage measured from the pelvic models. Two independent observers assessed related parameters (coverage, abduction angle, anteversion angle) from the 2D X-ray images, and inter-observer reliability was statistically analyzed. Differences between 2D and 3D acetabular coverage were compared, and multiple linear regression analysis was used to assess correlations between acetabular anteversion angle, abduction angle, and both 2D and 3D acetabular coverage.Results:The acetabular coverage for the 2D X-ray groups (AP, 15° iliac oblique, 30° iliac oblique, and 45° iliac oblique) was 87.37%±2.59%, 87.01%±2.53%, 85.39%±2.57%, and 83.20%±2.51%, respectively, with statistically significant differences ( F=6.700, P=0.001). The 45° iliac oblique group had significantly lower coverage than both the 30° iliac oblique group and the AP group, while the 30° iliac oblique group showed significantly lower coverage than the 15° iliac oblique group (all differences, P<0.05). The mean abduction and anteversion angles were 45.33°±2.22° and 14.61°±2.53°, respectively. The 3D acetabular coverage was 85.66%±2.51%. The 45° iliac oblique group had significantly lower coverage than the 3D coverage group ( P<0.05), whereas no significant difference was observed between the AP group and the 3D coverage group ( t=1.893, P=0.062). Multiple linear regression analysis revealed significant negative correlations between the acetabular abduction angle, anteversion angle, and both 2D and 3D acetabular coverage, with the following regression equations: 2D coverage=124.627-0.700× (abduction angle) -0.379× (anteversion angle) ( R2=0.814, P=0.001); 3D coverage=120.291-0.603× (abduction angle) -0.499× (anteversion angle) ( R2=0.917, P<0.001). Conclusion:Acetabular cup coverage rates vary with different X-ray projection angles, with the anteroposterior X-ray view potentially overestimating coverage. Changes in the abduction angle appear to significantly impact the differences between 2D and 3D coverage, thereby increasing errors in assessing true acetabular cup coverage. These discrepancies between 2D and 3D coverage should be carefully considered when evaluating minimal acetabular cup coverage.

Objective To evaluate the colonoscopy surveillance in colorectal cancer patients after surgical removal of the tumor.Methods From June 1986 to June 2007,2762 asymptomatic patients who had underwent operation for colorectal cancer were put into colonoscopy surveillance.They had the first examination 3-6 months after the operation,and were re-examined once a year thereafter for 3 years.The follow-up findings were compared with those from the 218 symptomatic patients who had colorectal cancer surgery from September 1981 to May 1986.Results In 2762 asymptomatic patients,48 cases of multiple primary cancer were detected,in which 39 cases(1.4%) were found at one examination and 9 cases(0.3%)at different examination.The TNM staging of these lesions included stage Ⅰ in 6,stage Ⅱ in 31 and stage Ⅲ in 11.During the surveillance,583 cases(21.1%) of adenoma were detected and endoscopically resected,in which 17(3.2%) were invasive early cancer and 58(9.9%) were high grade dysplasia.In 218 patients with symptoms,29 cases(13.3%) of adenoma and 27 cases( 12.4%) of cancer were detected,including 4 cases of stage Ⅰ cancer,6 of stage Ⅱ and 16 of stage Ⅲ.Conclusion Colonoscopy surveillance in colorectal cancer patients after surgery is important in finding precancerous lesion and early stage cancer,and is recommended in all patients.
