Objective To elucidate the evaluation of therapeutic effects and surgical treatments of 45 cases of inflammatory bowel disease. Methods Clinical data of 45 cases with inflammatory bowel disease by surgical treatment in recent 6 years were retrospectively analyzed. Results Patients received emergency operation in 16 cases, Crohn' s disease in 9 cases, Ulcerative Colitis( UC) in 7 cases. Among 13 cases of Crohn' s disease, partial enterectomy occured in 6 cases, partial enterectomy and colectomy and anastomosis in 1 patient because of internal fistula, repair of ileal perforation in 1 case, laparoscopic ileocolic resection in 5 cases. Among 32 cases of UC, 25 cases underwent ileal pouch-anal anastomosis operation, 3 cases underwent ileostomy with total colectomy, and 4 cases only underwent ileostomy. Twenty- seven cases were cured by operation, 14 cases were improved and 4 cases died. Conclusion It is the key point to achieve successful operation that the corresponding operative modes for varied manifestations of inflammatory bowel disease should be adopted.

Objective To evaluate the long-term functional outcome after ileal pouch anal anastomosis with modified double-stapled technique.Methods From January 2002 to March 2011,forty-five patients underwent ileal pouch anal anastomosis with modified double-stapled technique.The clinical data of these patients were reviewed.The postoperative anal function was assessed by Kirwan classification and Oresland pouch-specific function score.Results During the median follow-up of 65 months,2 patients with malignant adenomatous polyps died,2 patients were diagnosed dysplasia by biopsy,4 patients developed mild to moderate anastomotic narrowing,1 patient developed persistent anastomotic stricture needing surgical intervention,16 patients developed at least 1 episode of pouchitis.There was no incontinence in these patients,and the median functional Oresland score was 6,3 and 2 after 1 year,2.5 years and 5 years respectively.Conclusion The functional results of ileal pouch anal anastomosis with modified double-stapled technique are promising,with no incontinence in our patients.

Objective To compare the application,safety and theraputic effect of local resection of early rectal tumours by transanal endoscopic microsurgery(TEM) and the conventional transanal excision(TAE).Methods The data of seventy-six patients who were treated by conventional transanal excision from January 2003 to July 2006 and fifty-three patients who were treated by transanal endoscopic microsurgery from September 2006 to February 2010 in Ruijin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine were reviewed.Results Age,sex,tumour size,blood loss,postoperative hospital stay were similar in the two groups(P＞0.05).The median distance from the anal verge was significantly higher in the TEM group ( TEM/TAE =7.0/5.0 cm,P ＜ 0.01 ).The operation time was significantly longer in the TEM group (TEM/TAE =70.00/30.00 min,P ＜ 0.01 ).There was no operation-related mortality in both groups (P ＞ 0.05 ).Two patients in the TEM group developed postoperative haemorrhage,and one patient developed pulmonary infection and retention of urine respectively.There were two secondary haemorrhage cases in the TAE group.On median follow-up of 30 months,there was 7.8％ recurrence rate in the TEM group,compared with 23.2％ the in TAE group.Conclusions Transanal endoscopic microsurgery is a safe and effective mininally invasive surgical technique for the treatment of early rectal neoplasm.It has broader indication,and better theraputic effect than the conventional transanal excision.

Objective:To investigate the clinical features, risk factors, treatment and prognosis of dermatomyositis (DM) patients with positive anti-melanoma differentiation associated gene 5(MDA5) antibody with rapidly progressive interstitial lung disease (RPILD).Methods:The clinical data of 88 DM patients from June 2019 to June 2020, at the rheumatology department of Guangdong Provincial People's Hospital were collected and retrospectively analyzed. T-test, non-parametric Mann-Whitney U test, Chi-squared test, Fisher exact probability and Logistics regression analysis were used for data analysis. Results:① 37%(36/88) DM patients were positive for anti-MDA5 antibody. The frequency of ulcerative rash, Gottron's sign, arthritis, clinically amyopathic dermatomyositis (CADM), and erythrocyte sedimentation rate (ESR) was significantly higher in patients with anti-MDA5 antibody ( P<0.05). The cell count of white blood cell, neutrophil, lymphocyte, and serum creatine kinase (CK) level were significantly lower in the anti-MDA5 antibody positive group than those in the negative group ( P<0.05). Of anti-MDA5 antibody positive DM patients, 100% developed ILD, 34% (11/32)developed RP-ILD, 16%(5/32) died, which were significantly higher than those of anti-MDA5 antibody negative patients ( P<0.05). ② Of anti-MDA5 antibody positive DM patients, the C reactive protein (CRP) level, positive rate of anti-Ro-52 antibody and mortality rate were significantly higher RPILD group than those in the non-RPILD group [15.70(4.49, 29.00) vs 3.22 (1.66, 7.15), Z=-2.440, P=0.014; 91% vs 43%, P=0.011; 46% vs 0, P=0.002]. Logistics regression analysis indicated that positive anti-Ro-52 antibody [ OR=4.561, 95% CI (1.797, 11.580), P=0.001] might be a risk factor for anti-MDA5 antibody positive DM-RPILD. ③ Among patients with anti-MDA5 antibody with RPILD, serum ferritin and D-dimer level was significantly higher and oxygenation index was significantly lower in the non-survival group than those in the survival group [1 931 (1 377, 7 379) vs 638(196, 876), Z=-2.556, P=0.009; 2 760(1 995, 4 854) vs 985(533, 1 588), Z=-2.379, P=0.017; 230(140, 256) vs 309(262, 382), Z=2.191, P=0.030]. In addition, the delayed intensive treatment time was significantly longer in the non-survival group than those in the survival group [(14.0±2.6) vs (4.5±1.4), t=7.899, P<0.01]. Furthermore, the proportion of combined therapy with two disease modifying antirheumatic drug (DMARDs) was significantly lower in the non-survival group than those in the survival group (0 vs 83%, P=0.015). Conclusion:Anti-MDA5 antibody may be associ-ated with characteristic clinical manifestations of DM, ILD, RPILD and high mortality rate. Positive anti-Ro-52 antibody may be a risk factor for anti-MDA5 antibody positive DM-RPILD. High serum ferritin and D-dimer level and low oxygenation index in RPILD patients may be associated with poor prognosis. Early treatment with two DMARDs may improve the prognosis of RPILD.

Objective To study the pelvic fascia related to pelvic autonomic nerve and detect the anatomical localization of pelvic autonomic nerve by marker in adult male.Methods Twelve pelvises of adult male harvested from cadavers were studied by dissection.Results Hypogastric nerve was embedded in the posterior leaf of the visceral pelvic fascia.Pelvic plexus was situated between vesicohypogastric fascia and visceral fascia.Pelvic nerve branch of seminal vesicle and prostate was located at the anterolateral part of Denonvilliers fascia.Sacral promontory,ureter,junction of Denonvilliers fascia,visceral fascia and seminal vesicle could be regarded as anatomical markers for pelvic autonomic nerve.Conclusion The anatomical characteristics of pelvic autonomic nerve can be used for protecting and isolating pelvic autonomic nerve in total mesorectal excision of adult male.

Objective To evaluate the long-term therapeutic results of intersphincteric resection (ISR) in the treatment of ultra-low rectal cancer.Methods Sixty cases of ultra-low rectal cancer with the inferior border of the tumor within 5 cm to the edge of anus underwent intersphincteric resection (ISR),and the clinical data were analyzed retrospectively.There were 39 males,21 females and their average age was 55 years old (range from 30 to 77 years old).The inferior border of the tumor were from 28 to 50 mm to the edge of anus,averaging 42 mm.Results Sixty patients underwent intersphincteric resection successfully with 3 cases developing anastomotic leakage and 2 cases anastomotic stenosis postoperatively.After a median follow-up period of 49 months (range from 18 to 90 months),local and distant recurrence were observed in 6 and 4 patients respectively.Five-year overall survival rate and disease-free survival rate were 88.3％ and 83.3％ respectively.The mean stool frequency were (3.8 ± 1.3) times in each day based on data from 53 patients,and the stool control function of 73.6％ of all patients was preserved satisfactorily according to Kirwan classification.Conclusions This study indicated that intersphincteric resection might be a candidate technique in the treatment of early stage ultra-low rectal cancer restricted within rectal wall and could achieve satisfactory long-term results in both oncologic and functional respects.

Objective:To investigate the effect of iguratimod (IGU) on transforming growth factor-β 1 (TGF-β 1)-induced primary human lung fibroblasts (pHLFs) activation and collagen secretion. Methods:Mice pulmonary fibrosis (PF) models were established in vivo and were divided into three groups: the control group (CTR group), the Bleomycin (BLM) group and the BLM+IGU group, hematoxylin-eosin (HE) staining was used to observe lung morphology, and Masson staining was used to observe the degree of collagen accumulation in lung. Fibronectin and smooth muscle 22 (SM22) were detected by immunofluorescence, and the content of hydroxyproline in lung tissue was detected by chloramine-T method. In vitro, pHLFs were used to assess the effect of IGU on TGF-β 1 stimulation in four groups: CTR group, IGU group, TGF-β 1 group and TGF-β 1+IGU group, the apoptosis of cells was detected by flow cytometry, and the mRNA expression of collagen type Ⅰ (COL-Ⅰ) and collagen type Ⅲ (COL-Ⅲ) was detected by quantitative real-time polymerase chain reaction (qRT-PCR). The protein levels of α-smooth muscle actin (α-SMA), fibronectin, p-Smad2, p-Smad3 and transcription coactivator p300 were detected by Western blot and immunofluorescence. One-way ANOVA was used for all data, and LSD- t test or Kruskal-Wallis test was used for pair comparison. Results:The content of hydroxyproline in CTR group, the BLM group and the BLM+IGU group was (0.552±0.075) μg/mg, (1.293±0.081) μg/mg and (0.833±0.053) μg/mg ( F=169.672, P<0.01) respectively. IGU reduced the content of hydroxyproline in the lung tissue of mice, reduced the accumulation of collagen in the lung, and thus reduced the degree of BLM-induced pulmonary fibrosis, and improved the pathological changes in the lung of mice. In cell experiments, IGU had no significant effect on apoptosis ( F=0.83, P=0.54). The relative expression levels of COL-Ⅰ mRNA in the CTR group, TGF-β 1 group and TGF-β 1+IGU group were (100.4±1.2), (299.0± 13.0) and (202.5±7.0) respectively ( F=468.7, P<0.01). The relative expression levels of COL-Ⅲ mRNA in the CTR group, TGF-β 1 group and TGF-β 1+IGU group were (99.8±1.9), (350.6±8.0) and (220.3±9.9) respectively ( F=468.7, P<0.01). The relative expression levels of α-SMA protein were (0.193±0.038) in CTR group, (0.530±0.061) in TGF-β 1 group, and (0.410±0.065) in TGF-β 1+IGU group ( F=35.620, P<0.01); The relative expression levels of fibronectin in CTR group, TGF-β 1 group, and TGF-β 1+IGU group were (0.200±0.020), (0.700±0.020) and (0.410±0.066) respectively ( F=123.326, P<0.01). The relative expression levels of p-Smad3 protein in CTR group, TGF-β 1 group, and TGF-β 1+IGU group were (0.120±0.020), (0.573±0.586) and (0.327±0.252) respectively( F=92.987, P<0.01); The relative expression levels of p300 in CTR group, TGF-β 1 group and TGF-β 1+IGU group were (0.180±0.055), (0.923±0.025) and (0.650±0.050) respectively ( F=207.676, P<0.01). IGU significantly decreased the mRNA expression levels of COL-Ⅰ and COL-Ⅲ induced by TGF-β 1, inhibited the protein expression levels of α-SMA, fibronectin, p300, and phosphorylation of Smad2/3. Conclusion:Our results revealed the beneficial effect of IGU on the inhibition of TGF-β 1-mediated pHLFs activation and collagen secretion via the Smad3/p300 pathway, thus suggest that it might act as an effective anti-fibrotic agent in preventing the progression of PF.

Objective To investigate the feasibility and efficacy of laparoscopic subtotal colectomy and modified Duhamel procedure combined with transanal endoscopic microsurgery (TEM) in the treatment of severe functional constipation (SFC). Methods The clinical data of 10 patients with SFC treated by laparoscopic surgery combined with TEM between May 2010 and October 2012 in Ruijin Hospital of Shanghai Jiaotong University School of Medicine were retrospectively analyzed. The gastrointestinal quality of life index (GIQLI), Wexner constipation scale and daily frequency of defecation postoperatively during follow-up were collected. Results All the 10 operations were successfully accomplished laparoscopic subtotal colectomy combined with TEM without abdominal incision. There was no conversion to open procedure. One case had preventive terminal ileum stoma. The mean operative time was (256±58) min. The mean blood loss was (178±67) ml. The mean time to first flatus was (40 ±11) h. There were no ureteric injury, anastomotic leak, pelvic sepsis and other complications postoperatively. There was one case of insufficient small bowel obstruction which was released by conservative treatments. The patients were discharged from the hospital in (9.0 ±1.5) d postoperatively. The GIQLI in one year postoperatively was (112 ±10) points, which indicated good results compared to (75 ±12) points preoperatively (P=0.000). The Wexner constipation scale was 20.8 ±2.2 preoperatively and decreased to 5.2 ±1.8 at one year follow-up (P=0.000). Conclusion Laparoscopic subtotal colectomy and modified Duhamel procedure combined with TEM provides SFC patients a safe and feasible minimally invasive surgery.
