Recognition of traditional Chinese medicine for the structures of channels and collaterals is possibly related with the tactics of human early general medical study, characterized by "inner", sub-micro, entirety, etc. The mechanisms are possibly involved in direct communication pathway of the cell junction (specially keeping the relevant cellular direct communication relation in individual development), the extra-cellular matrix stress network system and its biophysical message transmission--force--meridian signs transformation--inter-cellular massage integration, and "generalization" of the structures and activities of channels and collaterals in acupuncture serum phenomenon, etc. Thus, the hypothesis of multi-factors about channel structures-mechanisms is proposed.

Objective To investigate the predicting value of Notch1 levels expressed in peripheral blood mononuclear cell (PBMC) for coronary artery calcification.Methods 300 consecutive patients with coronary artery disease (CAD) who hospitalizing in the department of cardiology in Guangzhou first people's hospital from January 2016 to June 2017 were enrolled.All Patients received 320-slice multi-detector row computed tomography scanning and coronary artery calcium sore(CCS)were measured.Patients were divided into three groups:control group (CCS =0),Low CCS group (CCS ＜97.6) and high CCS group (CCS ≥97.6) according to the mean value of CCS (CCS =97.6).Notch1 expressed in PBMC,serum interlekin-6 (IL-6) and high sensitivity C reactive protein (hs-CRP)of patients were examined and compared among three groups.Results The levels of Notch1 in PBMC and serum IL-6,hs-CRP of patients in high CCS group were significant higher than the other two groups [Notch1:7.02 ± 0.86 vs 6.32 ± 0.78 vs 5.49 ± 0.71;IL-6:(133.66 ± 10.18) μg/L vs (127.49 ± 10.79) μg/L vs (111.62 ± 9.87) μg/L;hs-CRP:(3.98 ± 1.02) mg/L vs (3.11 ±0.95)mg/L vs (2.56 ±0.76)mg/L] (P ＜0.05).The Spearman correlation analysis showed that the levels of Notch1 in PBMC were positive correlated with the levels of serum IL-6 and hs-CRP in enrolled patients with coronary calcification (P ＜ 0.05).Multivariate logistic regression analysis showed that the levels of Notch1 in PBMC and serum IL-6 were two strong independent risk factors for severity of coronary calcification in patients with CAD (P ＜ 0.05).Conclusions Notch1 expression in PBMC of patients with CAD was valuable to predicate the severity of coronary calcification.That the Notch1 signal path regulating the inflammation conditions in patients may be one of the most important mechanisms in the formation and progress of coronary calcification.

Objective Investigation of the significance for applying the percentage of neutrophils, neutrophil to lymphocyte ratio combined with contrast enhanced ultrasonography in the diagnose of coronary artery disease through examining the percentage of neutrophils, neutrophil to lymphocyte ratio on peripheral blood. Methods 130 patients with acute coronary syndrome (ACS group) , 90 patients with stable angina (SAP group) and 50 nonCAD patients (control group were observed. The neutrophils counts of all the patients were detected and Neut％, NLR were calculated; all the patients were asked to examine enhanced carotid contrast echocardiography. The plaque enhancement (DE) , and luminal enhancement ratio (Ratio) were recorded. The differences in neut％, NLR and CEUS were compared among the three groups. The Pearson correlation analysis was used to analyze the correlation between Ratio and Neut％, NLR. Multivariate logistic regression analysis was used to evaluate the predictive value of Neut％, NLR and CEUS for ACS. Results (1) The value of Neut％, NLR of the peripheral blood, DE, and Ratio in both ACS group and SAP group were higher than those in control group, and the value of ACS group was higher than that in SAP group (P < 0.05 or P < 0.01); (2) The analysis of Linear correlation showed that the ratio of CEUS in ACS patients was positively correlated with Neut％ (r = 0.422, P = 0.001) and NLR (r = 0.407, P = 0.001). (3) The ROC results showed that circulating Neut％, NLR and DE, Ratio play a significant role in the diagnose of unstable plague in CAD patients; (4) Multivariate logistic regression analysis showed that Neut％, NLR, DE, Ratio were independent indicators of the ACS patients (P< 0.05 or P < 0.01).Conclusions Contrast enhanced carotid examination combined with leukocyte analysis on peripheral blood were useful to detect plaque instability and inflammatory response in CAD patients, and it also provide lots of objective evidence for predicting and intervening unstable plaque in CAD patients.

OBJECTIVETo investigate the feasibility and application value of improved anvil placement in laparoscopic resection of low rectal cancer with resection of anal eversion.

METHODSA retrospective study was performed on 17 patients who were operated by improved extracorporeal anvil placement in laparoscopic resection of low rectal cancer with resection of anal eversion at Huaihe Hospital of Henan University during June 2015 and June 2017.

INCLUSION CRITERIA(1) distance from tumor low margin to anal edge was 4 to 6 cm; (2) protrusive type tumor with a circumferential diameter of less than 3 cm; (3) ulcer type tumor with circumferential bowel infiltration of less than 1/2; (4) no distant metastasis(M0) and preoperative MRI of pelvic floor indicating T1-3N0. Patients with BMI>35 kg/m, or insufficient length of sigmoid and mesentery, or thickening sigmoid and mesentery were excluded. According to total mesorectal excision(TME) principle, rectum and its mesentery was resected completely; the sigmoid colon was cut off at the superior margin of tumor; the oval forceps was placed through anus to clamp and evert the rectum out of the anus; the rectum was transected at 1-2 cm from the lower edge of the tumor; the distal sigmoid colon was pulled out through anus; purse string suture was made after insertion of anvil and was restored to the abdominal cavity; end-to-end anastomosis of the rectum and sigmoid colon was performed after closing rectal stump.

RESULTSOf 17 low rectal cancer patients, 10 were male and 7 were female with age of 42 to 71 (median 58) years old and BMI of 20.6 to 33.5(median 26) kg/m. Preoperative staging indicated 2 cases of stage I, 15 cases of stage II. Distance from tumor low margin to anal edge was 4 to 6(median 5.0) cm and diameter of tumor was 3.4 to 4.8 (median 4.2) cm. All the patients completed operations successfully without conversion to laparotomy. The operation time was 124 to 182 (median 136) minutes. Distal sigmoid colon was difficult to pull out in 1 patient due to the insufficient free of the mesosigmoid, which was then successful after the mesosigmoid was dissociated with laparoscopy thoroughly again. The intraoperative blood loss was 10 to 50 (median 20) ml. Postoperative pathology reveled 2 cases of stage I, 12 cases of stageII and 3 cases of stage III; 1 case of poorly differentiated adenocarcinoma, 15 cases of moderately differentiated adenocarcinoma and 1 case of highly differentiated adenocarcinoma. The postoperative exhaust time was 24 to 128 (median 36) hours and hospital stay was 5 to 15 (median 8) days. No anastomotic leakage and intra-abdominal infection was found. Fifteen patients were followed up for 5 to 24 months without local recurrence or distant metastasis.

CONCLUSIONThe improved anvil placement in laparoscopic resection of low rectal cancer with resection of anal eversion without abdominal incision is safe and feasible.

【Objective】 To investigate the clinical application of self-developed magnetic anchoring device for assisting thoracoscopic pulmonary resection. 【Methods】 Eleven patients underwent thoracoscopic pulmonary assisted with resection magnetic anchoring technique at the Department of Thoracic Surgery, The First Affiliated Hospital of Xi’an Jiaotong University, from March to May 2019. Their clinical data were retrospectively analyzed. The operation time, blood loss, blood transfusion volume, postoperative hospital stay, and postoperative complications were recorded. 【Results】 There were seven male and four female patients, with the average age of (51.6±13.9) years (range from 22 to 69 years). Three single-port and eight single-utility-port thoracoscopic surgeries were performed. Magnetic instruments provided good surgical field exposure in all operations. Among 11 surgeries, one was converted to thoracotomy and one to three-hole surgery due to enlargement and adhesion of hilar lymph nodes. The operation time was (107.8±63.1) minutes (range of 27-182 minutes). The blood loss was 50 (10-50)mL (range of 5-1 000 mL). No blood transfusion was needed during the operation. The postoperative hospital stay was (5.0±1.8) days (range of 3-9 days). No postoperative complications occurred in all the patients. 【Conclusion】 Magnetic anchor technique can effectively alleviate the "chopstick effect" in thoracoscopic surgery. Magnetic anchor technique is safe and feasible in assisting thoracoscopic pulmonary resection.
