Objective To investigate the value of two-dimensional echocardiography (2DE) in detecting left ventricular regional wall motion abnormality (RWMA) in non-ST-elevation myocardial infarction (NSTEMI) by contrast with coronary angiography (CAG).Methods Totally 68 cases of NSTEMI patients (NSTEMI group)and 50 cases of normal peoples (normal group)were collected.2DE dynamic image and CAG results were comparatively analyzed in two groups.Left ventricular RWMA of all patients were observed through multi-section dynamic images by 2 experienced echocardiographic physicians.Left ventricular wall motion abnormalities were determined according to the 16 segment method of the American Society of echocardiography (ASE).2DE-RWMA was positive if there were one or more segments of motion abnormalities.All NSTEMI patients underwent CAG 2 days after 2DE examination,CAG was positive if the degree of coronary artery stenosis was more than 50％.Results In 68 NSTEMI patients,66 cases were CAG positive and 2 cases were negative,35 cases were 2DE-RWMA positive and 33 cases were negative.Taking CAG as a gold standard,the sensitivity,specificity and accuracy,positive predictive value and negative predictive values of 2DE-RWMA in diagnosis of NSTEMI were 51.52％ (34/66),50.00 ％ (1/2),51.47％ (35/68),97.14％ (34/35),3.03 ％ (1/33).Compared with the 2DE-RWMA negative patients,the rate of three branches of coronary artery stenosis in 2DE-RWMA positive patients was higher (62.85％ vs 39.39％,P＜0.05),the degree of coronary artery stenosis that reached 90％-99％ was higher (68.57％ vs 48.48％,P＜0.05).Conclusion The sensitivity of 2DE is low of NSTEMI in detecting the left ventricle RWMA.The degree of coronary artery stenosis is probably serious if 2DE-RWMA is positive,which is helpful for preliminary clinical judgment.

Objective: To analyze the application of difficulty degree index (DDI) in predicting patients′s fertility outcome after laparoscopic myomectomy. Methods: A retrospective study was carried out on 118 patients with subserous myoma or intramural myoma undergoing laparoscopic myomectomy from January 2005 to December 2014. The rate of post-operative pregnancy, delivery outcome and disease recurrence were investigated. Logistic regression analysis was used to analyze the impact of DDI, the age of patients undergoing surgery, presence of infertility history etc, on the patients′ reproductive outcome following the surgery. Results: Follow-up for 1 to 10 years,118 cases were included in the study, the rate of post-operative pregnancy, live birth, vaginal delivery were 72.9% (86/118) , 52.5% (62/118) and 24.2% (15/62) respectively. No cases of uterine rupture and obstetric complications occurred. Univariate analysis showed that the independent variables of post-operative pregnancy rate were DDI, patient′s age at the time of surgery, presence of infertility history and myoma recurrence (all P<0.05) . In multivariate analysis, the factors of post-operative pregnancy rate were DDI (OR=3.131, 95%CI:1.012-8.894) , patient′s age at the time of surgery (OR=2.722, 95%CI:1.048-7.067) and presence of infertility history (OR=8.509, 95%CI: 2.102-34.445) . Conclusions DDI could be applied to predict post-operative pregnancy rate, with the increasing of DDI the post-operative pregnancy rate decreasing. The patients with high DDI scores, age>35 years old or presence of infertility history should get ready for pregnancy positively.

Objective: To compare the effects of 3 treatment strategies (emergent surgery, self-expanding metallic stents, self-expanding metallic stents plus neoadjuvant chemotherapy) on postoperative anal function and quality of life in patients with complete obstructive left hemicolon cancer. Methods: A retrospective cohort study was conducted. Clinical data of patients with complete obstructive left hemicolon cancer admitted to General Surgery Department of Beijing Chaoyang Hospital between January 2017 and October 2019 were retrospectively collected. Patient inclusion criteria: (1) complete obstructive left hemicolon cancer was confirmed through clinical manifestation and abdominal computed tomography; (2) adenocarcinoma was confirmed by postoperative pathology; (3) emergent radical resection of primary tumor was performed with temporary stoma, or radical resection of primary tumor and primary anastomosis was performed without stoma, 7 to 14 days after completion of insertion of self-expanding metallic stents. Patients who did not receive stoma reversion after emergent operation were excluded. According to different therapies, patients were divided into three groups: emergent surgery (ES) group, self-expanding metallic stents (SEMS) group and self-expanding metallic stents plus neoadjuvant chemotherapy (SEMS+NAC) group. Wexner score for incotinence (higher score indicates the worse anal function), Vaizey score (>10 indicates fecal incontinence) and low anterior resection syndrome (LARS) scale (higher score indicates the worse anal function) were applied to evaluate anal function of patients among groups at postoperative 1-, 6- and 12-month. EORTC QLQ-C30 questionnaire was used to assess the quality of life. Risk factors of decreased anal function were identified by logistic regression analysis. Results: A total of 72 patients were enrolled, including 27 (37.5%) patients in ES group, 23 (31.9%) in SEMS group and 22 (30.6%) in SEME+NAC group. The baseline characteristics including age, gender, tumor location, comorbidities, total blood loss, operation time and postoperative complications, were comparable among groups, except that the proportion of laparoscopic surgery was significantly lower in ES group (4/27, 14.9%) than that in SEMS (15/23, 65.2%) and SEMS+NAC group (16/22, 72.7%) with significant difference (P<0.001). The follow-up ended up to October 2020, and the overall follow-up rate was 79.2% (57/72). No significant differences existed in the Wexner score of patients among groups at postoperative 1-, 6- and 12-month (all P>0.05). The Vaizey scores at postoperative 1-month in ES, SEMS and SEMS+NAC group were 7 (0-17), 3 (0-7) and 4 (0-8) respectively with significant difference (H=18.415, P=0.001), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). Vaizey scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The LARS scores at postoperative 1-month in ES, SEMS and SEMS+NAC groups were 20 (0-37), 15 (0-24) and 16 (0-28) respectively with significant difference (H=3.660, P=0.036), and the scores in SEMS and SEMS+NAC groups were significantly lower than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC groups (P>0.05). LARS scores at postoperative 6- and 12-month among 3 groups were not significantly different (both P>0.05). The QLQ-C30 score revealed that the social function of patients in SEMS group and SEMS+NAC group was significantly better than that in ES group (both P<0.05), while no significant difference existed between SEMS and SEMS+NAC group (P>0.05). The logistic regression analysis revealed that only ES was an independent risk factor of decreased anal function (OR=2.264, 95% CI: 1.098-4.667, P=0.027). Conclusion: Compared to ES, SEMS may improve quality of life and short-term anal function of patients with complete obstructive left hemicolon cancer.

BACKGROUNDSurgical treatment of insertional Achilles tendinopathy should be considered when a variety of conservative measures fail. To achieve a satisfactory outcome, thorough debridement of the Achilles tendon is critical, besides excision of the bursitis and the calcaneal exostosis. Central tendon-splitting provides straightforward access to the calcified or degenerative tissue within the Achilles tendon. For Achilles tendon reconstruction if detachment is present, several surgical techniques have been reported. Controversy surrounds the technique can provide maximum security for reattachment of the Achilles tendon. The SutureBridge double-row construct, initially used in rotator cuff repair, is probably a good choice.

METHODSTen consecutive patients with insertional Achilles tendinopathy underwent tendon reattachment using the SutureBridge technique through a central tendon-splitting approach. We retrospectively evaluated the surgical outcomes, which included pre- and postoperative visual analog scale (VAS), postoperative Maryland Foot Score (MFS), postoperative range of motion of the affected ankle, and related complications. Follow-up was performed in the outpatient department.

RESULTSOne patient was lost to follow-up. Nine patients (two male and seven female; 12 feet) were reviewed with a minimum follow-up of six months (range 6-30 months). The postoperative VAS pain scores were markedly lower than the preoperative scores. Postoperative MFS was 92.1±8.0 (range 74-100). No intra- or postoperative complications were found, except for one case of delayed healing incision. At last follow-up, all affected ankles achieved their normal range of motion, and patients were able to resume daily activities without any assistive device.

CONCLUSIONSAlthough a randomized control trial with a larger sample may be necessary to compare the central tendon-splitting combined with the SutureBridge technique with other techniques, our results confirmed that it was a promising alternative for treatment of insertional Achilles tendinopathy.

OBJECTIVETo make a preliminary assessment of the feasibility of Endo GIATM Radial Reload with Tri-StapleTM Technology(Radial Reload) in laparoscopic anterior resection of low rectal cancer.

METHODSClinical data of 21 low rectal cancer patients undergoing laparoscopic anterior resection with the Radial Reload in our department between July 2014 and July 2015 were retrospectively analyzed.

RESULTSAll the rectums were achieved complete transection by the first stapler device firing and all the operations were performed successfully. No patient were converted to open surgery. The operative time ranged from 110.0 to 180.0(140.5±16.6) minutes, the blood loss ranged from 50.0 to 100.0(66.8±11.4) ml, and the distal resection margin ranged from 1.0 to 3.0(1.8±0.7) cm. Tumor cells were not discovered in all the postoperative pathological samples of distal resection margin. Among 21 cases, stage I( was found in 14 cases, stage II( in 4 cases and stage III( in 3 cases. There were no anastomotic bleeding and anastomotic leakage. There was no local recurrence and distant metastasis during a median follow-up of 6 months(1 to 13 months) postoperatively.

CONCLUSIONThe application of Radial Reload in laparoscopic anterior resection of low rectal cancer is feasible with satisfactory efficacy.

OBJECTIVETo explore the safety and curative effect of per anus intersphincteric rectal dissection and direct coloanal anastomosis (PIDCA) for patients with very low rectal cancer.

METHODSNineteen patients were prospectively studied from June 2002 to October 2004. There were 11 males and 8 females, with a median age of 56 (range, 41 - 74) years. Nineteen patients had T(1) to T(4) tumors (T(1), n = 4; T(2), n = 10; T(3), n = 4; T(4), n = 1) located between 3.5 and 5.0 cm above the anal verge.The rectum, including the entire width of the internal analsphincter, was transected circumferentially via the anal route to secure the surgical margin of safety under direct vision and was mobilized proximally as far as possible through the intersphincteric plane. Per anus coloanal anastomosis was performed following transabdominal resection of the rectum.

RESULTSThere was no operative mortality. Of nineteen patients, two (10.5%) had anastomotic leakage. Median follow-up duration was 16 (range, 3 - 29) months. Up to now, one patient developed recurrence (5.3%). Acceptable anal function results were obtained in most patients.

CONCLUSIONSCurability and anal function was obtained by PIDCA combined with preoperative or postoperative radiotherapy and postoperative chemotherapy. PIDCA is ideal and safe for selected patients with tumor located below 5 cm from the anal verge.

OBJECTIVETo evaluate the safety and efficacy of individual cylindrical abdominoperineal resection (CAPR) for locally advanced low rectal cancer.

METHODSFrom June 2011 to February 2012, 11 patients with locally advanced low rectal cancer underwent individual CAPR. There were 7 male and 4 female patients, aged from 32 to 74 years with a median of 64 years. Forty-seven patients underwent classic CAPR from January 2008 to February 2012. Preoperative and postoperative parameters such as clinical information of patients, tissue morphometry and complications were compared.

RESULTSIn the individual surgical group, 6 patients were treated with one side levator ani muscle totally or partially reserved, 3 patients with sacrococcyx reserved, and 2 patients with dissection close to the anterior rectal wall. Compared with classical surgery, the individual surgical specimens of horizontal section area ((2197 ± 501) mm(2)) and intrinsic muscle layer outer area ((1722 ± 414) mm(2)) were small, but the difference was not statistically significant (P = 0.150 and 0.167). The operative time, intraoperative blood loss, circumferential resection margin, total cross sectional tissue area, cross sectional tissue area outside the muscularis propria and bowel perforation rate between the two groups were not significantly different. Individual CAPR showed less incidence of chronic perineal pain (2/11, χ(2) = 6.116, P = 0.013) and sexual dysfunction (2/9, χ(2) = 4.412, P = 0.036) compared with classic CAPR.

CONCLUSIONSIndividual CAPR has the potential to reduce the risk of chronic perineal pain and sexual dysfunction without influencing the radical effect when compare with classic CAPR for the treatment of low rectal cancer.

BACKGROUNDIt was reported that telomerase expression is closely associated with cellular immortality and cancer. This study was designed to investigate the relationship between telomerase expression and the carcinogenesis of cervical cancer, the possible use of telomerase as a marker of cervical intraepithelial neoplasia (CIN) progression or regression, and the natural history of CIN.

METHODSTelomeric repeat amplification protocol (TRAP) assay was used to measure telomerase activity in cervical scrapings and biopsy samples obtained from 105 cases affected with various cervical conditions, including chronic cervicitis (n = 20), CIN (n = 64, 16 cases of CIN I, 20 cases of CIN II, and 28 cases of CIN III), and invasive squamous cell carcinoma (n = 21).

RESULTSIn exfoliated cell samples, telomerase activity was detected in 5 of 20 (25.0%) cases of cervicitis, 10 of 16 (62.5%) cases of CIN I, 11 of 20 (55.0%) cases of CIN II, 23 of 28 (82.1%) cases of CIN III, and 13 of 21 (61.9%) cases of carcinoma. In cervical biopsy samples, telomerase activity was detected in 6 of 20 (30.0%) cases of cervicitis, 8 of 16 (50.0%) cases of CIN I, 9 of 20 (45.0%) cases of CIN II, 27 of 28 (96.4%) cases of CIN III, and 20 of 21 (95.2%) cases of carcinoma. Telomerase activation was significantly higher in CIN samples than in cervicitis samples. Telomerase activity was detected at similar frequency in samples from cervical scrapings and cervical biopsies.

CONCLUSIONThese results seem to suggest that telomerase expression may be associated with carcinogenesis of the cervix. TRAP assay of cervical scraping samples could be used to monitor and predict the development of CIN in clinical practice.

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.

BACKGROUNDObstructive sleep apnea (OSA) syndrome has a negative impact on the health of millions of adolescents and youth. The aim of this study was to evaluate the associations of OSA syndrome with obesity and cardiometabolic risk factors among adolescents and youth at risk for metabolic syndrome (MS).

METHODSA total of 558 subjects aged 14-28 years were recruited from the Beijing Child and Adolescent Metabolic Syndrome Study. Each underwent a 2-h oral glucose tolerance test (OGTT), echocardiography, and liver ultrasonography. Anthropometric measures, blood levels of glucose, lipids, and liver enzymes were assessed. Subjects with high or low risk for OSA were identified by Berlin Questionnaire (BQ).

RESULTSAmong the subjects in obesity, 33.7% of whom were likely to have OSA by BQ. Subjects with high risk for OSA had higher neck and waist circumference and fat mass percentage compared to those with low risk for OSA (P < 0.001). Moreover, significant differences in levels of lipids, glucose after OGTT, and liver enzymes, as well as echocardiographic parameters were found between the two groups with high or low risk for OSA (P < 0.05). The rates of nonalcoholic fatty liver disease (71.0% vs. 24.2%), MS (38.9% vs. 7.0%), and its components in high-risk group were significantly higher than in low-risk group.

CONCLUSIONSThe prevalence of OSA by BQ was high in obese adolescents and youth. A high risk for OSA indicates a high cardiometabolic risk. Mechanisms mediating the observed associations require further investigation.
