Objective To investigate the predictive value of serum procalcitonin (PCT) combined with anion gap (AG) detection on the prognosis of patients with sepsis. Methods One hundred and seventeen patients with sepsis treated in our hospital from January 2019 to January 2021 were selected as study subjects and divided into survival group (78 patients) and death group (39 patients) according to their prognosis at 28 d of admission. The general data of the two groups was compared, multi-factor Logistic analysis of high-risk factors of sepsis patients was performed, area under the ROC curve was applied to assess the predictive value of serum PCT combined AG detection on the prognosis of sepsis patients. Results After comparing the general data of the two groups, the differences in age, neutrophil count, C-reactive protein (CRP), PCT, AG and APACHE II scores were statistically significant (P<0.05); multi-factor Logistic regression analysis showed that age, CRP, PCT and AG levels were risk factors for death in sepsis patients; the results of ROC curve analysis showed that the area under the curve of serum PCT was 0.737, with an optimal cut-off value of 9.595; the area under the AG curve was 0.791, with an optimal cut-off value of 21.695;the area under the curve of serum PCT combined with AG was 0.933, and the optimal cut-off value was 1.3442. Conclusions Serum PCT combined with AG assay had a high predictive value for the prognosis of patients with sepsis.

Objective To analyze the correlation between the expressions of inflammatory factors in vaginal lavage fluid and persistent infection of high-risk human papillomavirus(HR-HPV). Methods A total of 80 patients with HR-HPV persistent infection in our hospital from March 2019 to March 2021 were selected as the experimental group. According to the pathological examination results, 19 patients with cervical cancer were selected as the experimental group 1, 30 patients with CIN grade I were selected as the experimental group 2, and 31 patients with CIN grade II and III were selected as the experimental group 3. Thirty healthy women in the same period were selected as the control group. HR-HPV load, TGF- β, IFN-γ, IL-17 and IL-6 levels were detected and were compared among the four groups. Pearson analysis of correlation between TGF- β, IFN-γ, IL-17, IL-6 levels and HR-HPV load was carried out. Results There were significant differences in the levels of inflammatory factors in vaginal lavage fluid and HR-HPV load among the four groups (P<0.05). TGF- β、IL-17 and IL-6 levels were positively correlated with HR-HPV load and negatively correlated with IFN-γ (P<0.05). Conclusions There is a certain correlation between inflammatory factors in vaginal lavage fluid and HR-HPV load in patients with HR-HPV persistent infection. HR-HPV load is negatively correlated with IFN-γ, and positively correlated with TGF-β, IL-17 and IL-6. The degree of HPV infection could be evaluated by detecting the inflammatory factors in vaginal lavage fluid.

Objective To investigate the correlation between the expressions of negative regulatory cell CD4⁺CD25⁺T and its related cytokines in peripheral blood and bacterial infection of patients with chronic obstructive pulmonary disease (COPD). Methods Sixty-six COPD patients admitted between January 2018 and December 2019 were included as the research subjects, including 36 patients with acute exacerbation of COPD (AECOPD) and 30 patients with stable COPD. Another 30 healthy people undergoing physical examination during the same period were included in control group. The expression levels of CD4⁺CD25⁺ regulatory T cell and its related cytokines [interleukin-4 (IL-4), interleukin-10 (IL-10), interferon-γ (IFN-γ)] in the peripheral blood samples were detected among the included subjects. The relationship between levels of related indicators and presence or absence of bacterial infection in COPD and the efficacy of predicting infection were analyzed.

The levels of CD4⁺ and CD4⁺CD25⁺were negatively correlated with IL-4 and IFN-γ (P<0.05), and the CD4⁺level was negatively correlated with IL-10 (P<0.05). The CD4⁺ level in COPD patients with infection was lower than that in patients without infection (P<0.05), while the levels of IL-4 and IFN-γ were higher than those in patients without infection (P<0.05). The CD4⁺CD25⁺level of COPD patients with Gram-negative bacteria infection was lower than that of patients without infection (P<0.05), while the IL-10 level was higher than that of patients without infection (P<0.05).

Methods The data of 30 patients with pathologically diagnosed with colorectal cancer were collected. All patients were treated with mFOLFOX6 (5-fluorouracil+oxaliplatin+calcium leucovorin) chemotherapy. The self-control study was carried out before, during, and after chemotherapy, and cardiac ultrasound was performed to obtain conventional parameters, and three-dimensional dynamic images of the left ventricular apex four-chamber, three-chamber, two-chamber section, short-axis mitral valve, papillary muscle, and apical sectionare were acquired.

Results No matter before or after chemotherapy, there was a transmural gradient in each layer of myocardium. Compared with those before chemotherapy, the absolute values of myocardial strain parameters of each layer were reduced after chemotherapy, and GLSendo and GCSendo and ΔGLS decreased more significantly (P<0.05),while the area under the ROC curve of GLSendo was 0.766, P<0.001.Selecting 25.3% as the diagnostic boundary, the sensitivity was 83.3%, and the specificity was 70%.The area under the ROC curve of ΔGLS was 0.749, P<0.001. Selecting 4.1% as the diagnostic boundary, the sensitivity was 76.7%, and the specificity was 73.3%. Conclusions The myocardial layer-specific strain analysis is helpful for early detection of changes in the myocardial function of the left ventricle, which caused by mFOLFOX6 in patients with colorectal cancer. GLSendo and ΔGLS are sensitive indicators in this technique.

Objective To observe the application of failure mode and effect analysis (FMEA) in monitoring analysis and protection countermeasures of blood-borne occupational exposure of medical personnel. Methods FMEA was used to retrospectively analyze the high risk factors of blood-borne occupational exposure of medical staff in our hospital from January 2018 to June 2019, to calculate the risk priority number (RPN), to give priority to the highest risk factor, to formulate improvement measures. The improved scheme was adopted from July 2019 to December 2020. The RPN value of failure mode, blood-borne occupational exposure and Chinese Hospital Safety Atmosphere Scale (C-HSCS) before and after the implementating of the scheme were compared and analyzed. Results After implementating FMEA, RPN and weight coefficient (W_i) decreased, and the RPN scores were 2 633 and 853 before and after implementation, with a decrease of 67.60%, W_i was 0.729 9 before implementation and 0.268 0 after implementation, with a decrease of 63.28%. Before FMEA, the blood-borne occupational exposure rate was 28.74%, and after FMEA, the rate was 4.65%. After the implementation, the scores of safety work obstruction was (11.99±2.16), cleanliness and tidiness was (11.48±1.89), management and support was (28.58±3.24), conflict and communication was (22.54±2.83), feedback and training was (13.82±2.55), which were higher than those before the implementation: (10.67±2.68), (10.06±2.36), (26.80±3.86), (20.85±2.62), (12.52±1.19), P<0.05. Conclusions Using FMEA in the management of blood-borne occupational exposure of medical personnel could refine high-risk steps, improve the pertinence of improvement measures and reduce occupational exposure.
