Purpose: To observe the clinical efficacy on acupuncture treatment of functional dyspepsia. Methods: Major points including Zusanli (ST 36) were selected on the basis of meridian theory to treat functional dyspepsia with even reinforcing-reducing manipulations and electric stimulation. While commonly-used western medication domperidone was used in a control group. Results and conclusions: The total effective rate and the markedly effective rate were 93.8% and 63.3% respectively in the acupuncture group and 82.2% and 43.1% respectively in the medication group. The curative effect on nonspecific functional dyspepsia was better in the acupuncture group than in the medication group (P<0.05).Both treatments had marked effects on the dyskinetic type without a significant difference (P>0.05).

ObjectiveTo evaluate the clinical value of magnifying endoscopy in diagnosis and treatment of colorectal benign neoplastic lesions.Methods78 colorectal lesions in 61 patients were examined with magnifying colonoscopy after indigo carmine dye, and a pit pattern diagnosis was made for every lesion according to Kudo's classification.All the lesions were totally resected, and the specimen were sent for pathologic examinations.ResultsThe diagnostic sensitivity of neoplastic lesions was 98.4% and specificity was 85.7% when types Ⅰ and Ⅱ represented the pit pattern of nonneoplastic lesions, whereas types Ⅲ, Ⅳ, and Ⅴ represented adenoma and early colorectal cancer. The overall accuracy in differentiating adenoma and early colorectal cancer from nonneoplastic lesions was 96.2%.94.5% of adenomarous lesions were treated by colonoscopy.ConclusionThe magnifying colonoscopy can provide an instantenous accurate diagnosis of tumorous lesions in colon and rectum. Synchronize, minimally invasive and curative treatment is possible to be completed by using it for a large number of lesions.

Objective To determine serum vascular endothelial growth factor (s-VEGF) and serum endostatin (s-endostatin) levels in patients with colorectal cancer after preoperative regional intraarterial chemotherapy (PRAC). Methods Peripheral venous blood was sampled preoperatively and postoperatively, and was assayed for VEGF and endostatin by ELISA. Results Patients' preoperative level of s-VEGF and s-endostatin elevated significantly, which was in close correlation with Dukes' stage. The level of s-VEGF and s-endostatin before chemotherapy elevated significantly compared with that on day 7 after chemotherapy and on postoperational day 1 and 14 after operation. In patients undergoing palliative resection, only the level of s-endostatin before chemotherapy was significantly higher than that on day 1 after operation. Conclusions PRAC, inhibiting angiogenesis, is of antitumor effect, the decrease of s-endostatin after chemotherapy may suggest the combination of chemotherapy and antiangiogenesis for a better antitumor effect.

Extralevator abdominoperineal excision (ELAPE) has been described to improve the outcomes of advanced low rectal cancer, probably because of more pelvic dissection and less positive circumferential resection margin (CRM). Recent improvements of ELAPE have focused on the reconstruction of the large pelvic defect. Different approaches have been focused on the reconstruction including primary closure, uterus retroversion, omentoplasty, myocutaneous flaps, and biological mesh. The optimal method is still controversial. Recent reviews showed that the perineal wound complications of biological mesh reconstruction were comparable to those of myocutaneous flaps. Moreover reviews suggested the use of biologic materials to close the perineal defect because it offers a significant cost saving mostly attributable to reduction in hospital length of stay. The combination of different techniques may be the best way to reconstruct the pelvic defect following ELAPE.

Objective: To evaluate the long-term healing rate of transsphincteric anal fistula treated with anal fistula plug procedure and the risk factors affecting the healing of anal fistula. Methods: A retrospective case-control study was conducted to analyze the clinical data of 207 patients with transsphincteric anal fistulas who received anal fistula plug procedure at the Department of General Surgery, Beijing Chaoyang Hospital of Capital Medical University from August 2008 to September 2012. Inclusion criteria: (1) consistent with the diagnosis of transsphincteric anal fistula: the anal fistula passed through the internal and external sphincter; (2) complete data; (3) initial treatment with anal fistula plug procedure. Exclusion criteria: (1) acute rectal or perianal infection or poorly controlled focal infection; (2) recent incision and drainage of perianal abscess or spontaneous rupture of abscess; (3) patients with malignant tumor; (4) patients with Crohn′s disease or ulcerative colitis; (5) patients with heart, liver, brain, lung or renal insufficiency; (6) cachexia due to various chronic wasting diseases; (7) patients could not tolerate surgery. Patients were followed up for anal fistula healing. The cumulative healing rate of patients with transsphincteric anal fistula was plotted using the Kaplan-Meier method, and the factors affecting anal fistula healing were explored by univariate and multivariate logistic regression analysis. Results: There were 186 males and 21 females with age of 15 to 69 (mean 38) years. The duration of anal fistula was 3-60 (mean 15) months. Three patients had a history of previous episodes of perianal abscess and underwent incision and drainage of perianal abscess (all more than 3 months). During follow-up ending on October 31, 2018, 72 patients (34.8%) were lost to follow-up. Among 135 patients who were successfully followed up, the average follow-up period was 96 (75-124) months. Seventy-five patients had anal fistula healing, with healing rate of 55.6%. Kaplan-Meier survival curve showed that the healing time of anal fistula was prolonged and finally stabilized at 55.6%. In the patients who failed initial treatment with anal fistula plug packing, there were 6 cases whose anal fistula healed spontaneously without other treatment. Among them, 3 cases healed spontaneously 2 years and 3 cases 3 years after operation without recurrence. From 2008 to 2012, the annual healing rates of anal fistula plug treatment were 3/6, 61.5% (24/39), 42.1% (24/57), 12/15 and 12/18, respectively. Multivariate logistic regression analysis showed that the duration of anal fistula≥6 months (OR=3.187, 95% CI: 1.361-7.466, P=0.008) was an independent risk factor for anal fistula healing after treatment with anal fistula plug. Conclusion The long-term efficacy of anal fistula plug procedure in the treatment of transsphincteric anal fistula is positive, and this procedure should be implemented as soon as possible.

OBJECTIVETo evaluate the laparoscopy combined with transperineal extralevator abdominoperineal excision (TP-ELAPE) for locally advanced low rectal caner.

METHODSClinical data of 12 patients with locally advanced low rectal cancer undergoing laparoscopy combined with TP-ELAPE in our department from May 2013 to March 2015 were retrospectively analyzed. There were 8 male and 4 female patients with median aged of 63 (46 to 72) years. The median distance from tumor lower margin to anal verge was 3.5(2.0 to 4.0) cm. A self-made transanal suit for minimally invasive operation was used to make a sealed lacuna outside the sphincter, thus laparoscope can be applied to perform transperineal operation.

RESULTSAll the patients underwent operations successfully without conversion to open abdominal operation. The median operating time was 206 (180 to 280) minutes with perineal operating time 95(80 to 120) minutes. The median intraoperative blood loss was 120(50 to 200) ml. The median postoperative hospital stay was 12(9 to 18 ) days. Postoperative pathology revealed that all circumferential margins (CRM) were negative. The area of sample horizontal section was (2 824±463) mm(2), and of outer muscularis propria was(2 190±476) mm(2). Postoperative complications included chronic sacrococcygeal region pain in 2 cases, urinary retention in 3 cases, perineal wound infection in 1 case. No perineal seroma, perineal hernia, wound dehiscence and sinus tract formation were observed. Among 8 patients with preoperative normal sexual function, sexual dysfunction occurred in 2 patients. There was no local recurrence and metastasis during a median follow-up of 21(12 to 34) months.

CONCLUSIONLaparoscopy combined with TP-ELAPE has the potential to simplify the operation procedure for low rectal cancer, can ensure the radical treatment and safety of operation, and may be carried out in experienced centers.

Objective:To explore the effect of peripheral blood T lymphocyte subsets on locally advanced rectal cancer after neoadjuvant chemoradiotherapy.Methods:108 patients were included at the Department of General Surgery of Beijing Chaoyang Hospital from Jun 2016 to Jun 2017. Peripheral blood was collected within one week before neoadjuvant therapy and one week before rectal surgery. Flow cytometry was applied to detect the CD3 + 、CD4 + 、CD8 + 、CD45RA + 、CD45RO + expression. Receiver operating characteristic (ROC) curve analysis was performed to determine the best cut-off value of the ratio of lymphocytes. A logistic regression model was obtained in multivariate analysis. Results:The values of CD3 + , CD4 + and CD8 + T lymphocytes in peripheral blood of the patients decreased compared with that before neoadjuvant treatment (all P<0.05). There was no significant decrease in the proportion of CD4 + , CD8 + , CD45RA + T and CD45RO + lymphocytes in patients′ peripheral blood (all P>0.05). The CD45RO in peripheral blood decreases during neoadjuvant therapy for locally advanced rectal cancer, and it is associated with better tumor regression( P<0.05). The best cut-off value for the ratio changes of CD45RO was 1.07. The ratio changes of CD45RO were the only significant factor for tumor regression in multivariate analysis ( P=0.005, OR=26.867, 95% CI: 1.530-471.635). Conclusion:The percentage of peripheral blood CD45RO may predict the sensitivity of neoadjuvant therapy in rectal cancer patients.

Objective:To investigate the clinical effect of modified atlantooccipital decompression combined with occipitocervical internal fixation on Chiari type I malformation combined with syringomyelia and atlantoaxial dislocation.Methods:Twenty-five patients with Chiari I malformation combined with syringomyelia and atlantoaxial dislocation accepted by modified atlantooccipital decompression combined with occipitocervical internal fixation in our hospital from January 2011 to March 2019. The clinical data of these patients were retrospectively analyzed. The changes of peak velocity of cerebrospinal fluid in the dorsal part of the spinal cord, electrophysiological results, atlantodental interval (ADI) values, sizes of syringomyelia, and Chicago Chiari outcome scale (CCOS) scores before and after operation were compared.Results:The peak velocity of cerebrospinal fluid in the dorsal spinal cord after surgery ([3.25±0.47] cm/s) was statistically higher in these patients than that before surgery ([2.13±0.19] cm/s, P<0.05). As compared with the preoperative results, ADI values, sizes of syringomyelia, and proportion of patients with abnormal electrophysiological monitoring at 6 months after surgery were significantly decreased, and CCOS scores at 6 months after surgery were significantly increased ( P<0.05). There were no new nerve function damage, infection, cerebrospinal fluid leakage, paralysis, respiratory failure or death. Conclusions:Modified atlantooccipital decompression combined with occipitocervical internal fixation plays effective role in atlantooccipital decompression and atlantoaxial anatomical reduction in patients with Chiari malformation type I combined with syringomyelia and atlantoaxial dislocation. The remission rate of syringomyelia is high, the symptoms and signs improve obviously, and the postoperative complications are less.
