ABSTRACT
Objective:To evaluate the predictive value of neutrophil-to-lymphocyte ratio (NLR) for adult severe tetanus by comparing the NLR in patients with severe and mild tetanus.Methods:A total of 65 adult tetanus patients from the Linyi Central Hospital from January 2009 to December 2020 were enrolled. The patients were divided into two groups including mild group and severe group according to the Ablett classification. The general conditions, laboratory data, and NLR of patients in two group were retrospectively compared using independent samples t test. Multivariate logistic regression analysis was used for the analysis of risk factors for severe tetanus. Spearman correlation method was used for the analysis of the correlation between risk factors and Ablett grades. Receiver operator characteristic (ROC) curve was used for the evaluation of the predictive value. Results:Among the 65 tetanus cases, 34 was in mild group and 31 in severe group. The latency period of patients in severe group was (7.00±3.19) d, which was shorter than that in mild group ((9.18±2.59) d), and the difference was statistically significant ( t=3.03, P=0.004). The NLR of patients in severe group was 4.251±1.936, which was higher than that of mild group (2.533±1.026) , and the difference was statistically significant ( t=4.41, P<0.001). Multivariate logistic regression analysis showed that NLR and latency period were independent risk factors for tetanus severity (odds ratio ( OR)=2.359, 95% confidence interval ( CI) 1.415 to 3.934, P=0.001 and OR=0.748, 95% CI 0.599 to 0.936, P=0.011, respectively). In tetanus patients, the NLR level was positively correlated with Ablett grade ( r=0.644, P<0.001). The ROC curve showed that NLR had good predictive value for adult severe tetanus at a cut-off value of 2.471 (area under the curve (AUC)=0.787), with the sensitivity and specificity of 87.1% and 61.8%, respectively. When combining NLR with latency period (cut-off value of 7.5 d), predictive efficiency was further improved (AUC=0.832) with the sensitivity of 87.1% and specificity of 67.6%( Z=3.43, P<0.001). Conclusions:NLR has a good predictive value for adult severe tetanus, and the predictive efficiency is further improved when combined with latency period.
ABSTRACT
Objective:To investigate the differential diagnostic value of intravoxel incoherent motion diffusion-weighted imaging (IVIM-DWI) combined with serum indicators for prostate cancer.Methods:We recruited 97 patients with prostate diseases who received treatment in Zhuji People's Hospital from March 2018 to September 2020 for this study. Patients with prostate cancer were included in the study group ( n = 46) and patients with benign prostatic hyperplasia in the control group ( n = 51). All patients were subject to IVIM-DWI and serum early prostate cancer antigen-2 level detection alone or in combination. The sensitivity, specificity, accuracy, and diagnostic efficacy of IVIM-DWI and serum early prostate cancer antigen-2 level detection alone or in combination were compared between the two groups. Results:D and f values in the study group were (0.50 ± 0.14) × 10 -3 mm 2/s and (0.35 ± 0.11), respectively, which were significantly lower than those in the control group [(0.71 ± 0.12) × 10 -3 mm 2/s, (0.59 ± 0.08), t = 7.95, 12.37, both P < 0.001]. D* value and serum early prostate cancer antigen-2 level in the study group were (6.24 ± 1.90) × 10 -3 mm 2/s and (62.5 ± 18.3) μg/L, which were significantly higher than those in the control group [(4.08 ± 1.34) × 10 -3 mm 2/s, (17.3 ± 6.8) μg/L, t = -6.52, -16.43, both P < 0.001]. The overall detection rate, sensitivity, specificity, and accuracy of IVIM-DWI combined with serum early prostate cancer antigen-2 level detection for prostate cancer were 53.6% (52/97), 97.8% (45/46), 74.5% (38/51), and 85.6% (83/97), respectively. A receiver operating characteristic curve analysis showed that the sensitivity of IVIM-DWI combined with serum indicators in the diagnosis of prostate cancer and the area under the curve were greater than those produced by IVIM-DWI and serum early prostate cancer antigen-2 level detection alone (both P < 0.05). Conclusion:IVIM-DWI combined with serum early prostate cancer antigen-2 level detection has a higher sensitivity in the diagnosis of prostate cancer than monotherapy. The combined therapy provides a new perspective for the differential diagnosis of prostate cancer and has a certain clinical value.

Different centers collected and summarized their data in 2017 and sent back the questionnaires for summary.@*RESULTS@#A total of 8 766 AA patients were enrolled from 43 medical centers, including 4 711 males (53.7%) with median age of 39 years and 958 (10.9%) patients over 65 years old. Of 8 776 patients, 5 677 cases (64.6%) received one or more imaging examinations, and the other 3 099 (35.4%) did not receive any imaging examination. A total of 1 858 (21.2%) cases received medical treatment, mainly a combination of nitroimidazoles (1 107 cases, 59.8%) doublet regimen, followed by a single-agent regimen of non-nitroimidazoles (451 cases, 24.4%), a nitroimidazole-free doublet regimen (134 cases, 7.2%), a triple regimen of combined nitroimidazoles (116 cases, 6.3%), nitroimidazole alone (39 cases, 2.1%) and nitroimidazole-free triple regimen (3 cases, 0.2%). Of the 6 908 patients (78.8%) who underwent surgery, 4 319 (62.5%) underwent laparoscopic appendectomy and 2589 (37.5%) underwent open surgery. Ratio of laparotomy was higher in those patients under 16 years old (392 cases) or over 65 years old (258 cases) [15.1%(392/2 589) and 10.0%(258/2 589), respectively, compared with 8.5%(367/4 316) and 8.0%(347/4 316) in the same age group for laparoscopic surgery, χ²=91.415, P<0.001; χ²=15.915,P<0.001]. Patients with complicated appendicitis had higher ratio of undergoing open surgery as compared to those undergoing laparoscopic surgery [26.7%(692/2 589) vs. 15.6%(672/4 316), χ²=125.726, P<0.001].The cure rates of laparoscopic and open surgery were 100.0% and 99.8%(2 585/2 589) respectively without significant difference (P=0.206). Postoperative complication rates were 4.5%(121/2 589) and 4.7%(196/4 316) respectively, and the difference was not statistically significant (χ²=0.065, P=0.799). The incidence of surgical site infection was lower (0.6% vs. 1.7%, χ²=17.315, P<0.001), and hospital stay was shorter [6(4-7) days vs. 6(5-8) days, U=4 384 348.0, P<0.001] in the laparoscopic surgery group, while hospitalization cost was higher (median 12 527 yuan vs. 9 342 yuan, U=2 586 809.0, P<0.001).@*CONCLUSIONS@#The diagnosis of acute appendicitis is still clinically based, supplemented by imaging examination. Appendectomy is still the most effective treatment at present. Laparoscopic appendectomy has become the main treatment strategy, but anti-infective drugs are also very effective.

Objective:To investigate the clinical application value of nano-carbon tracer technology in lymph node dissection and postoperative pathological examination in laparoscopic mid-low rectal cancer resection.Methods:Fifty-two patients with mid-low rectal cancer were randomly divided into experimental group (n=27) and control group (n=25).Before surgery,the Nano-group were injected nano activated carbon suspension liquid under the mucosa.Both groups were accepted the same principles of open colorectal cancer radical surgery.The total number of lymph nodes,number of tiny lymph nodes,number of black dye and number of metastasis lymph node confirmed by pathology in the two groups were statistical analysised.Results:There were 905 pieces of lymph node seized in two groups toally,including (20.67 ± 5.751) medals in Nano-carbon group and (13.88 ±4.466) medals in control group.Lymph node number in nano carbon group was more than control group (P＜0.01).Nano-carbon group seized 113 tiny lymph nodes,significantly higher than 49 in the control group (P＜0.05).The metastasis rate of lymph node was no significant difference in the two groups (P＞0.05).Nano-carbon group seized lymph node metastasis was no significant difference in the rate of the control group (P＞0.05).Nano-carbon group seized 341 black dyed lymph nodes and 217 not black dye lymph nodes.And 67 cases of metastasis lymph nodes in Black dye lymph nodes,15 cases of metastasis lymph nodes in not the black dye lymph nodes.The metastasis rate of black dye lymph node was higher(P＜0.01).Conclusions:Nano-carbon tracer technique can guide the surgeon to accurately lymph nodes dissection during the operation,and can add to the number of lymph nodes in the postoperative surgical specimens,improve lymph nodes in patients with colorectal cancer radical seized quantity.Nano-carbon tracer technique can ensure the accuracy of the pathological staging,there was important clinical significance to lymph node dissection in Mid-low colorectal cancer,which provide an important basis for the development of postoperative adjuvant therapy programs.
