Objective:To investigate the correlation between microRNA-497 (miR-497) expression and invasion and metastasis and prognosis of colorectal cancer (CRC).Methods:The expression of miR-497 in 93 CRC patients (CRC group), 30 colorectal adenoma polyps (colorectal adenomatous polyp group) and 30 healthy patients (normal control group)were detected by real-time fluorescence quantitative polymerase chain reaction (qRT-PCR); meanwhile, the content of serum carcinoembryonic antigen (CEA) was detected by chemiluminescence; After 3 years follow-up, the expression of miR-497 was measured again; the correlation between the expression of miR-497 and the clinicopathological characteristics and prognosis of CRC was analyzed.Results:The expression of miR-497 in CRC group was significantly lower than that at the end of postoperative treatment, adenomatous polyps group and normal control group ( P<0.01), and the content of CEA in CRC group was significantly higher than that at the end of postoperative treatment, adenomatous polyps group and normal control group ( P<0.01); At the end of postoperative treatment, the expression of serum miR-497 in CRC group was lower than that in normal control group ( P<0.05), and the content of serum CEA was higher than that in normal control group ( P<0.05). The diagnosis positive rate of serum miR497 expression in CRC group was significantly higher than that of serum CEA ( P<0.01), and they showed no correlation ( r=0.232, P>0.05). The pre-and post-operative serum miR-497 expression levels in the recurred and metastasis group were significantly lower than those in the no postoperative recurrence and metastasis group ( P<0.01). The preoperative expression of miR-497 was related to the differentiation degree of CRC, tumor node metastasis (TNM) stage, lymph node metastasis, distant metastasis and survival period ( P<0.01), but not with the age, sex, tumor size and location of the patients ( P>0.05). Cox multivariate analysis showed that tumor differentiation, TNM stage, preoperative miR-497 expression, lymph node metastasis and distant metastasis were all independent risk factors influencing prognosis of CRC patients ( P<0.05); The survival rate of 1, 2, 3 years in the miR-497 low expression group was lower than that in the miR-497 high expression group ( P<0.05). Conclusions:The preoperative low serum miR-497 expression levels are closely relative with invasion and metastasis and poor prognosis of CRC, and can be a prognostic indicator of CRC. The reduced postoperative serum miR-497 expression levels may be a predictor of the postoperative recurrence and metastasis of CRC.

Objective To investigate the effects of Lotensin on inflammatory factors, vascular endothelial function and heart function in patients with acute myocardial infarction. Methods 100 cases with acute myocardial infarction from March 2015 to January 2016 in the fifth central hospital of Tianjin were selected as the research object, which were randomly divided into the control group and the observation group. The control group were given routine treatment, at this basis, the observation group were given Lotensin. After treatment, the cardiac function, the levels of inflammatory factors, the blood vessel endothelial function, the serum NO and endothelin 1 and the therapeutic effect in the two groups were compared. Results LVESV, LVEDV (156.28±3.29、213.45±6.12) mL in the observation group were better than (162.98±4.16、202.83±7.16) mL in the control group (P<0.05). LVEF was (48.72± 2.13)% in the observation, which was higher than (40.62±3.29)% in the control group(P<0.05). Hs-CRP, IL-6 were (2.66±0.68) mg/L、(4.90±0.92) ng /L in the observation group , which were less than (6.35±1.50) mg/L、(9.38±2.01) ng/L in the control group (P<0.05). FMD(10.37±0.62)% in the observation group was bet er than (6.16±0.92)% in the control group (P<0.05)、 NO, ET-1 level (71.52±13.21) μmol/L、(56.27±7.10) ng/L in the observation group were bet er than (60.63 ±10.57) μmol/L、(69.72±9.50) ng/L in the control group (P<0.05). The total effective rate in the observation group was 94.00% (47/50), which was better than 62.00% (31/50) in the control group (P<0.05). Conclusion The effect is significant which Lotensin is used in the treatment of acute cerebral infarction, which can reduce inflammatory factors, improve endothelial function and cardiovascular function.

Objective To investigate the status of work fatigue of the disabled and the healthy so that we get to know their employment quality and compressive strength, and then provide the theory basis for the national policy formulation and vocational rehabilitation. Methods We randomly investigated 280 employees (220 disabled, 60 healthy people) in 3 companies from 3 provinces with Fatigue Impact Scale (FIS). Results There was no statistically significant difference between disabled and healthy people about work fatigue, and also that of 3 domains including psycho-social, cognitive and physical activity. After comparison of 40 items on FIS，the disabled had higher fatigue than that of the healthy in 4 items which belonged to psycho-social domain (P<0.05). Conclusion Disabled people are no less than healthy people in compression capability and working capability. They should believe in themselves, and their family and the employees should have more confidence about their work capability than before. Government should provide some support with them on job retention.

Objective: To investigate the clinical application and effect evaluation of failure mode and effect analysis (FMEA) in the optimization of vascular recanalization in patients with ST-segment elevation myocardial infarction (STEMI). Methods: A total of 389 STEMI patients admitted to the emergency department of the Fifth Central Hospital in Tianjin from January 2014 to January 2015 were served as the control group, and 398 STEMI patients admitted to the chest pain center of the Fifth Central Hospital in Tianjin from January 2016 to October 2017 were served as the experimental group. In the control group, routine emergency treatment was used. At the same time, the intervention room was 24-hour prepared for emergency vascular recanalization. The experimental group used FMEA. Through the usage of FMEA, the main factors those caused the delay in revascularization treatment were determined, and the revascularization process was optimized for these influencing factors, thereby shortening the "criminal" blood vessel opening time of patients. The door-to-balloon dilatation time (D-to-B time), troponin testing time, placement time of the catheterization room, initiation of the catheterization room to balloon dilatation time, and preoperative and 1 week postoperative N-terminal pro-brain natriuretic peptide (NT-proBNP) levels, heart function parameters [left ventricular ejection fraction (LVEF), left ventricular short axis shortening rate (FS), left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD)] within 1 week, 3 months and 6 months after intervention, and the incidence of main cardiovascular adverse events within 1 month after intervention, hospital mortality, the length of hospital stay, and readmission within 1 year in the patients of two groups were recorded. Results: D-to-B time (minutes: 70.6±3.6 vs. 79.4±8.7), troponin testing time (minutes: 17.1±2.3 vs. 65.2±6.5), placement time of the catheterization room (minutes: 28.9±9.8 vs. 52.3±12.2) and activation of the catheterization room to balloon expansion time (minutes: 47.3±9.3 vs. 65.1±7.2) in the experimental group were significantly shorter than those in the control group (all P < 0.01). The NT-proBNP levels at 1 week after intervention in the two groups were lower than the preoperative levels, slightly lower in the experimental group, but the difference was not statistically significant. There was no significant difference in cardiac function at 1 week and 3 months after intervention between the two groups. The LVEF and FS at 6 months after intervention in the experimental group were significantly higher than those in the control group [LVEF: 0.622±0.054 vs. 0.584±0.076, FS: (38.1±4.3)% vs. (35.4±6.2)%, both P < 0.01], and LVESD and LVEDD were decreased significantly [LVESD (mm): 31.2±3.8 vs. 34.7±4.2, LVEDD (mm): 49.2±5.3 vs. 52.4±5.6, all P < 0.01]. The length of hospital stay in the experimental group was significantly shorter than that in the control group (days: 8.3±3.2 vs. 13.2±6.8, P < 0.01), the incidence of major cardiovascular adverse events within 1 month after intervention [13.6% (54/398) vs. 19.8% (77/389)], hospital mortality [1.8% (7/398) vs. 4.9% (19/389)], and readmission rate within 1 year [9.5% (38/398) vs. 14.5% (56/389)] in the experimental group were significantly lower than those in the control group (all P < 0.05). Conclusion The usage of FMEA to optimize the vascular recanalization procedure can shorten the emergency treatment time of STEMI patients, reduce the occurrence of adverse events, and improve the prognosis.

OBJECTIVETo observe clinical efficacy of using free anterolateral thigh flaps with iliotibial tracts in repairing skin and soft tissue defects around the knee joints with patellar ligament defects.

METHODSTwelve patients with skin and soft tissue defects around the knee joints and patellar ligament defects were hospitalized from June 2010 to June 2014. The defects of skin and soft tissue ranged from 7 cm × 6 cm to 16 cm × 12 cm in area, and patellar ligament ranged from 5 to 12 cm in length and 2.5 to 4.0 cm in width. Free anterolateral thigh flaps with iliotibial tracts were used to repair these defects. During reconstruction of patellar ligament, both ends of iliotibial tract were successively folded to form tendon-like three-layer structure at first, and then the newly formed structure was wrapped around the broken ends of patellar ligament and fixed with suture. The flap size ranged from 9 cm × 8 cm to 18 cm × 14 cm. The iliotibial tract ranged from 7 to 14 cm in length and 8 to 12 cm in width. The donor sites were closed by grafting with autologous split-thickness skin harvested from thigh or trunk, and parked with gauze. Immediately after operation, the knee joints were fixed in extension with orthosis for 6 weeks. Weight bearing training of affected limbs being kept in extension position was started from 2 weeks after operation, and flexion and extension exercise of affected knee joints was begun from 6 weeks after operation. Before operation and 12 months after operation, the degree of pain around the knee joints and knee joint function were evaluated with the international knee documentation committee knee uation form, and the ranges of flexion and extension of knee joints were also evaluated. The integrity of reconstructed patellar ligament was assessed by color Doppler ultrasound from 6 to 12 months after operation. The occurrence of surgery-related complications was observed in all patients within 12 months after operation.

RESULTS(1) After operation, all flaps survived well, and all wounds healed well. (2) The average score of pain around the knee joint was increased from 31 points before operation to 77 points in 12 months after operation. The average score of knee joint function was increased from 14 points before operation to 65 points in 12 months after operation. Before operation, the average ranges of flexion and extension of knee joint were respectively 89° and 65°, and they were respectively increased to 130° and decreased to 15° in 12 months after operation. From 6 to 12 months after operation, color Doppler ultrasound showed that the condition of reconstructive patellar ligaments in all patients was good without the need for further surgical intervention; the superficial sensation of the flaps was recovered in different degrees. No surgery-related complication was observed in all patients within 12 months after operation.

CONCLUSIONSFree grafting of anterolateral thigh flap with iliotibial tract is an effective and reliable method for repairing skin and soft tissue defects around the knee joints combined with patellar ligament defects, and the surgical procedure can recover function and appearance of knee joint satisfactorily.

Arrhythmogenic right ventricular dysplasia/cardiomyopathy (ARVD/C) is a genetic cardiac muscle disease that accounts for approximately 30% sudden cardiac death in young adults. The Ser358Leu mutation of transmembrane protein 43 (TMEM43) was commonly identified in the patients of highly lethal and fully penetrant ARVD subtype, ARVD5. Here, we generated TMEM43 S358L mouse to explore the underlying mechanism. This mouse strain showed the classic pathologies of ARVD patients, including structural abnormalities and cardiac fibrofatty. TMEM43 S358L mutation led to hyper-activated nuclear factor κB (NF-κB) activation in heart tissues and primary cardiomyocyte cells. Importantly, this hyper activation of NF-κB directly drove the expression of pro-fibrotic gene, transforming growth factor beta (TGFβ1), and enhanced downstream signal, indicating that TMEM43 S358L mutation up-regulates NF-κB-TGFβ signal cascade during ARVD cardiac fibrosis. Our study partially reveals the regulatory mechanism of ARVD development.
