Objective To explore and analysis the electrocardiogram manifestations,related clinical manifestations and pathological vascular characteristics of acute occlusion of the circumflex branch. Methods A total of 46 cases of acute myocardial infarction caused by circumflex branch occlusion diagnosed and treated in Hebi People's Hospital from January 2018 to June 2023 were selected as the study subjects,and the electrocardiographic manifestations,related clinical manifestations and characteristics of diseased blood vessels of the patients were detected and investigated,and the prognosis of the patients was followed up. Results Among the 46 patients,23 cases were diagnosed with proximal mid-segment occlusion（proximal mid-segment group）and 23 cases were diagnosed with distal segment occlusion（distal segment group）by coronary angiography．There was no significant difference in the comparison of the general data of the two groups（P>0.05）．The ECG features of ST V1- V3 depression,ST Ⅱ,Ⅲ,aVF elevation,ST Ⅱ,Ⅲ,aVF depression,TV2>TV5,ST I-aVL depression,ST I-aVL elevation and ST V7-V9 elevation in the proximal mid-segment group were 60.87%,47.83%,8.70%,43.48%,and 69.57%,17.39%,60.87%,and 4.35%,82.61%,0%,17.39%,30.43%,8.70%,60.87% in the distal segment group;there were similarities in the electrocardiographic manifestations of the proximal mid-segment group and the distal segment group as well as their respective characteristics．All patients were followed up until August 1,2023,and the mean follow-up time of the proximal mid- and distal segment groups was 32.69±4.20 months versus 32.92±3.28 months,and the incidence of adverse cardiovascular events was 26.09% in the proximal mid-group．There was no difference in the incidence of cardiovascular adverse events between the two groups（P>0.05）．ROC curve analysis showed that the area under the prediction curve of electrocardiogram for patients with acute occlusion of the proximal circumflex artery were 0.793（95% CI：0.678-0.914,P<0.001）,sensitivity was 78.22% and specificity was 81.91%．Conclusions Electrocardiogram has important predictive value in diagnosing acute myocardial infarction in which the infarct related artery is a circumflex branch．It can auxiliary determine the infarct site of patients and also auxiliary evaluate the prognosis of acute myocardial infarction patients．

Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ²=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ²=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P＜0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.

Objective To explore the clinical effect of super gamma knife in the treatment of advanced pancreatic cancer. Methods 46 patients with advanced pancreatic cancer admitted to our hospital from January 2015 to January 2019 were randomly divided into control group (23 cases)and observation group (23 cases). The control group received chemotherapy only; the observation group received super gamma knife treatment. We collected the clinical benefit response (CBR)and other indicators of treatment efficiency and survival time of the two groups for comparative analysis. Results One month after the intervention of different treatment measures, the total effective rate of the two groups was compared. The total effective rate of the observation group was 60.87%, which was higher than that of the control group (13.04%)(P<0.01). The positive rate of pain degree improvement, KPS physical strength improvement, body weight improvement in the observation group were all higher than those in the control group (P<0.05), but there was no statistical significance between the two groups in the positive rate of analgesic consumption improvement (P>0.05). The median time of progression free survival was 4 months (95% CI, 2.124±5.274)in the observation group and 3 months (95% CI, 1.804±4.851)in the control group. The median time of progression free survival in the observation group was longer than that in the control group (P = 0.042<0.05). Conclusion The super gamma knife based on the stereotactic gamma ray systemic therapy system uses the medium dose segmentation method to treat the advanced pancreatic cancer. Its clinical effect is practical, the side effects are relatively low, and the survival treatment of patients has a significant improvement effect, which is worthy of clinical promotion.

Objective To evaluate clinical application of using Turbohawk atherectomy device in combination with drug-coated balloon in treatment of atreriosclerosis obliterans in lower extremity. Methods Turbohawk atherectomy device and DCB was performed in 8 patiments with atreriosclerosis obliterans in lower extremity. All patients were diagnosed by ultrasound and CTA. Routine anticoagulation drugs were used after the operation. Follow-up was carried out with color Doppler ultrasound. Results Revascularization was gained in 8 patients. The technically successful rate was 100% and ischemic symptoms relieved significantly immediately after the operation. The post-operative ankle brachinal index(ABI) was 0.78±0.06,which was higher than that of before operation(0.31±0.12). No obvious complications occurred after operation. The follow-up range was 3~18 months and limbs were salvaged successfully. Conclusion With minimal invasive, safe and few complications, Turbohawk atherectomy device in combination with drug-coated balloon is proved to be a very effective treatment atreriosclerosis obliterans in lower extremity and it is worth to popularize.
