Objective To study the reliability and validity of measuring hip joint range of motion(ROM) with mobile APP (Goniometer Pro,G-pro). Methods The hip joint ROM was measured with a protractor and iPhone APP (G-pro), 12 subjects participated in this trial. Tester A used a protractor and iPhone APP (G-pro) to measure the flexion angle of the hip joint. Tester B used the mobile APP to measure the hip flexion angle again. Twenty-four hours later, tester A used the mobile APP to measure the hip flexion angle again under the same conditions. The validity was evaluated by analyzing the measurement results of protractor and mobile APP. The inter group and intra group reliability was studied by comparing the two measurements of tester A and tester B, and twice measurements of tester A. Results There was no significant difference between the measurements of protractor and iPhone APP by the same tester (P＞0.05). There was no significant difference in the twice measurements of tester A using iPhone APP (P＞0.05), and there was no significant difference in measurements of tester A and tester B using iPhone APP (P＞0.05). Conclusions The iPhone APP (Goniometer Pro) has good reliability and validity in measuring hip ROM.

Objective To evaluate the value of ultrasonography scoring system in differential diagnosis of well-differentiated liposarcomas (WDLPS) and benign lipoma (LP), and to provide evidence for the differential diagnosis and treatment choice. Methods Fourteen WDLPS cases (total of 15 masses) and 37 LP cases (total of 40 masses) were diagnosed by surgical histopathology, which clinical data and the ultrasound images were analyzed retrospectively. The parameters including age, gender, region, mass length, length/width ratio, shape, margin, envelope echoes, echogenicity, texture, location, blood flow were compared between the groups above. A scoring system was established by analyzing the parameters with statistical differences, and the ROC curve was plotted to calculate the best cut-off value and evaluate the diagnostic efficiency of the scoring system. Results There were statistically significant differences between two groups in the following six parameters: age, mass length, length/width ratio, envelope echoes, location, blood flow(P＜0.05). The scoring system was established by assigning 0 or 1 point to each factor, and the total score was 0～6 points. The highest diagnostic efficiency of WDLPS was observed at the cut-off value ≥ 3. The sensitivity, specificity, accuracy, the positive predictive value and the negative predictive value was 86.7%, 77.5%, 80%, 59.1%, 93.9% respectively. Conclusions The ultrasonography-based scoring system has a better diagnostic efficacy in differentiating WDLPS and LP, which can provide an important reference basis for the selection of clinical treatment, and is worthy of promotion and application.

Objective To compare the efficacy and safety of remimazolam tosilate and propofol in painless ultrasonic gastroscopy. Methods In a randomized, single-blind controlled study, 60 patients undergoing ultrasonic gastroscopy were selected and divided into observation group (31 cases) and control group (29 cases). Observation group was anesthetized with remimazolam tosilate, while control group was anesthetized with propofol. Two groups' hemodynamic index, perioperative adverse events, changes of MOAA/S score, awakening and departure time were observed at different time points during anesthesia. Results The observation group had less changes on hemodynamics. The observation group had enough depth of sedation, while the control group had a deeper degree of sedation. The onset time of the two groups was similar and both awoke quickly and left, but the awakening time and leaving time in the observation group were slightly shorter. Adverse events in the control group were more than those in the observation group. Conclusions Remimazolam tosilate for painless ultrasonic gastroscopy had little effect on hemodynamics, which can generate enough depth of sedation, and make patients wake up quickly. In addition, the incidence of its adverse events was low, and the overall effectiveness and safety were superior to those of propofol.

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. Results The levels of CD4⁺, CD4⁺CD25⁺ and IFN-γ/IL-4 in patients with AECOPD and patients with stable COPD were lower than those in control group (P<0.05), while the levels of IL-4 and IL-10 were higher than those in control group (P<0.05). The IFN-γ level of AECOPD patients was higher than that of control group (P<0.05). The levels of CD4⁺ and CD4⁺CD25⁺of AECOPD patients were lower than those of stable COPD patients (P<0.05), while the levels of IL-4, IL-10 and IFN-γ were all higher than those of stable COPD patients (P<0.05). 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). CD4⁺, IL-4, IL-10 and IFN-γ were effective indicators in predicting bacterial infection in COPD patients (P<0.05), and IL-4 and IFN-γ had higher efficacy. Conclusions CD4⁺, CD4⁺CD25⁺ T cell and related cytokines are involved in the occurrence and development of COPD and bacterial infection in patients. Monitoring changes of those levels is helpful to provide information for clinical diagnosis and treatment.

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%.
