Objective To investigate the factors that induce constipation in bedridden patients undergoing replantation of severed finger and find countermeasures. Methods A retrospective investigation was carried out in 92 patients undergoing replantation of severed finger, their constipation and factors influencing constipation were recorded. Results 61 patients suffered from constipation in total 92 cases,the rate being 66.30%. 76 patients reduced food intake, and 59 cases presented constipation (the rate being 77.63%). Factors influencing constipation included being unaccustomed to defecate in bed (the rate that present with constipation being 87.09%),reluctant to trouble others(75.47%), side effects of drugs(55.56%) and lack of dietary knowledge (71.87%), decreasing food intake was closely bound up with constipation. Conclusions Proper psychological counseling, strengthening of health propaganda, comfortable facility for defecation, improved family support and oral food intake can significantly reduce the proportion of constipation and increase comfort degree of patients.

A temporary demand pacemaker with electrocardiosignal display is introduced in this paper. Double way low-noise electrocardiosignal preamplifier, amplitude limiter, high and low pass filter, 50 Hz notch filter, TTL level generator and stimulating pulse formation circuit are components of the hardware electrocircuit. The demand pacing and the electrocardiosignal display are separately controlled by the software in which the double microcontrollers communications technique is used. In this study, liquid crystal display is firstly used in body surface electrocardiosignal display or intracardial electrophysiologic signal display when the temporary demand pacemaker is installed and put into use. The machine has proven clinically useful and can be of wide appliation.

Objective:To explore the early clinical diagnostic indicators in patients with primary hepatocellular carcinoma (HCC) combined with macrovascular invasion.Methods:The clinical data of 180 cases of HCC diagnosed by histopathology examination in the Second Affiliated Hospital of Chongqing Medical University from 2012 to 2019 were retrospectively analyzed. The factors influencing the development of macrovascular invasion in HCC patients were analyzed. The receiver operating characteristic curve (ROC curve) was used to evaluate the sensitivity and specificity.Results:Serum C-reactive protein (CRP) level was significantly correlated with various clinical characteristics of HCC patients, including the maximum tumor diameter, tumor number, and macrovascular invasion. Further analysis of the risk factors showed that serum direct bilirubin and CRP were independent risk factors for macrovascular invasion in HCC patients, with odds ratios of 1.747 (95% CI 1.119-2.728, P = 0.014) and 2.376 (95% CI 1.495-3.775, P < 0.001). ROC curve analysis showed that serum CRP, direct bilirubin, and the combination of the both had certain diagnostic value for hepatocellular carcinoma combined with macrovascular invasion. The area under the curve, sensitivity and specificity was 0.724, 0.668, 0.743, 79.1%, 70.1%, 79.1%, and 61.9%, 62.8%, 67.3%, respectively. Conclusion:The combination of CRP with direct bilirubin can be used as an important clinical diagnostic indicator for early diagnosis and prevention of hepatocellular carcinoma combined with macrovascular invasion.

Objective:To analyze the clinical characteristics of pesticide poisoning patients and explore the risk factors of acute kidney injury (AKI) .Methods:In September 2020, the clinical data of 155 patients with pesticide poisoning in the department of nephropathy, the Affiliated Hospital of Southwest Medical University from September 2018 to August 2020 were retrospectively analyzed. The patients were divided into AKI group (44 cases) and non AKI group (111 cases) according to the occurrence of AKI. The clinical characteristics, organ or system involvement and auxiliary examination results of the two groups were analyzed. Logistic regression was used to analyze the risk factors of AKI in patients with pesticide poisoning.Results:The types of pesticides causing poisoning mainly included herbicides, insecticides and biochemical pesticides. Compared with non AKI group, patients in AKI group had higher proportion of blood purification treatment and ICU monitoring treatment ( P<0.05) , and were more likely to be complicated with acute respiratory failure, pulmonary fibrosis, myocardial injury, multiple organ dysfunction syndrome (MODS) , acute pancreatitis and coagulation abnormalities ( P<0.05) . The mortality of AKI group (18.2%, 8/14) was significantly higher than that of non AKI group (0.9%, 1/111) ( P<0.05) . Univariate analysis showed that the time from poisoning to treatment > 6 h, high WBC count, neutrophil count, alanine aminotransferase, aspartate aminotransferase, high sensitive troponin T, myoglobin and creatine kinase isoenzyme were the risk factors of AKI in patients with pesticide poisoning ( P<0.05) . Multivariate logistic regression analysis showed that the time from poisoning to treatment >6 h was an independent risk factor for AKI in patients with pesticide poisoning ( P<0.05) . Conclusion:The mortality of AKI secondary to pesticide poisoning is high. Attention should be paid to the time from poisoning to treatment, inflammatory state and changes of liver and myocardial function.
