In order to meet the accuracy requirements of hospitals for abnormal detection of fetal monitor data,a hospital fetal monitor data anomaly detection method based on Euclidean distance was proposed.In this method,according to the abnormal detection method of fetal monitor data in hospitals,the ultrasound Doppler detector was used to collect fetal heart rate signal data,and the fetal heart rate signal denoising method based on adaptive filtering was used to remove the noise components of the collected fetal heart rate signal.The denoised fetal heart rate signal was used as the identification sample of the abnormal fetal heart rate signal identification method based on Euclidean distance method.The Euclidean distance Euclidean distance between the denoised fetal heart rate signal and the normal fetal heart rate signal was analyzed by combining the Euclidean distance method and the strong classifier to analyze whether the virtual sinusoidal distance between the denoised fetal heart rate signal and the normal fetal heart rate signal was greater than the tuned Euclidean distance threshold.Fetal heart rate signal samples greater than the threshold were classified and diagnosed as abnormal monitoring data.The fetal heart rate information collected by the fetal monitor in the hospital was accurate,and the abnormal detection results were valid and reliable.

Objective To investigate the effects of nicorandil combined with rosuvastatin calcium on monocyte-to-high density lipoprotein cholesterol ratio (MHR), systemic immune-inflammation index (SII), and cardiac function in patients with coronary slow flow (CSF). Methods A group case-control study was used to select 240 patients with CSF confirmed by coronary angiography, and they were randomly divided into observation group and control group, with 120 patients in each group. On the basis of conventional drug treatment, the control group was treated with rosuvastatin calcium, while the observation group was treated with nicorandil combined with rosuvastatin calcium for 6 months. Clinical efficacy, inflammatory markers[high-sensitivity C-reactive protein (hs-CRP), MHR, SII], corrected TIMI frame count (CTFC) of major coronary branches [left anterior descending branch (LAD), left circumflex branch (LCX), right coronary artery (RCA)], cardiac function indicators[left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVEDD), global longitudinal strain (GLS)], and the occurrence of major adverse cardiovascular events (MACE) were compared between the two groups. Results The total effective rate in the observation groupwas significantly higher than that in the control group (95.00% versus 80.00%, P < 0.05). After treatment, the duration, severity, andfrequency of angina pectoris attacks were reduced or shortened in both groups, with more changes observed in the observation group (P < 0.05). Serum levels of hs-CRP, MHR, and SII were lower in both groups after 6 months of treatment, and the observation group with significantly was lower compared to the control group (P < 0.05). CTFC values of LAD, LCX, and RCA were also lower in both groups after 6 months, with the observation group showing significantly lower values (P < 0.05). The absolute values of LVEF and GLS increased in both groups after 6 months of treatment, and the observation group was higher than the control group (P < 0.05). However, no significant difference was observed in LVEDD and occurrence of MACE between the two groups (P>0.05). Conclusion The application of nicorandil combined with rosuvastatin calcium in the treatment of CSF patients can significantly improve the overall treatment efficacy, reduce hs-CRP, MHR, and SII levels, enhance cardiac function indicators such as LVEF, LVEDD, and GLS, and effectively alleviate the severity of angina pectoris attacks.

Objective:To evaluate the safety of ensartinib in the treatment of anaplastic lymphoma kinase (ALK) -positive non-small cell lung cancer (NSCLC) in the real-world clinical setting.Methods:Clinical data of 2 221 patients with ALK-positive locally advanced or metastatic NSCLC who received ensartinib treatment (225 mg/d) from December 16, 2020 to December 16, 2021 were collected and analyzed to assess drug adverse reactions in all population including elderly patients (≥ 65 years old) .Results:Among the total 2 221 patients, 511 patients (23.01%) experienced adverse events, including 8 patients (0.36%) who experienced serious adverse events. Adverse events led to dose modification in 67 patients (3.02%) and discontinuation in 18 patients (0.81%). The common adverse events were rash (407/2 221, 18.33%), pruritus (41/2 221, 1.85%), constipation (41/2 221, 1.85%), and facial edema (31/2 221, 1.40%). Thirty-six patients (1.62%) experienced ≥grade 3 adverse events. After symptomatic treatment of 511 patients with adverse reactions, 50 patients (9.78%) were healed, 271 patients (53.03%) were improved, 120 patients (23.48%) were persisted, and 70 patients (13.71%) were unknown due to loss of follow-up or other reasons. Forty-three patients (1.94%) reported 57 unintended adverse reactions. Among the 599 elderly patients, 116 patients (19.37%) experienced adverse events, including 1 patient (0.17%) who experienced serious adverse events. Adverse events led to dose modification in 25 patients (4.17%) and discontinuation in 5 patients (0.83%). The common adverse events of elderly patients were rash (88/599, 14.69%), constipation (14/599, 2.34%), facial edema (12/599, 2.00%), and pruritus (10/599, 1.67%). Twelve patients (2.00%) experienced ≥grade 3 adverse events. Among the 116 elderly patients with adverse reactions following the symptomatic treatment, 11 patients (9.48%) were healed, 58 patients (50.00%) were improved, 28 patients (24.13%) were persisted, and 19 patients (16.39%) were unknown due to loss of follow-up or other reasons. During the treatment, 1 patient (0.05%) experienced grade 2 interstitial lung disease, and no patient died due to adverse events.Conclusion:Ensartinib has a favorable safety profile in the real-world populations, with the most frequent adverse events being rash, mostly mild, and low incidence of ≥grade 3 adverse events. Overall, adverse reactions were tolerable and manageable.

Objective:To compare the characteristics of MSM with different types of primary sexual partners and to analyze the factors associated with MSM not being tested for HIV in the last six months.Methods:MSM were recruited in nine cities of Shandong Province from April to July 2021, and face-to-face questionnaires were conducted to collect information on sociodemographic characteristics, high-risk behaviors, and HIV testing of MSM. Blood samples were taken for serological tests of HIV and syphilis antibodies.Results:A total of 3 008 men who had anal sex with men in the last six months were divided into three groups according to the type of primary sexual partner in the last six months: the fixed sexual partner group (36.83%, 1 108/3 008), the commercial sexual partner group (3.06%, 92/3 008), and casual sexual partner group (60.11%, 1 808/3 008). There were statistically significant differences in the distribution of age, local residence time, education level, the primary place to find male sexual partners, use of new-type drugs in the last six months, consistent condom use every time during same-sex anal sex in the last six months, group sex in the last six months, no HIV testing in the last six months, having had a sexually transmitted disease in the last year, receiving peer education in the last year, and frequency of syphilis testing in the last year among different groups ( P<0.05). Multivariable logistic regression analysis showed that related factors of not being tested for HIV in the last six months in MSM were those aged less than 30 years old (a OR=1.39, 95% CI: 1.06-1.83), married/cohabiting (a OR=1.74, 95% CI: 1.39-2.16), high school education or less (a OR=1.39, 95% CI: 1.15-1.67), had not used new-type drugs in the last six months (a OR=2.27, 95% CI: 1.89-2.71), had not received peer education in the last year (a OR=1.59, 95% CI: 1.28-1.98), had never been tested for syphilis (a OR=11.30, 95% CI: 8.15-15.66), had not been tested in the last year but had been previously tested for syphilis (a OR=5.65, 95% CI: 4.19-7.62), the type of primary sexual partner in the last six months being a commercial sexual partner (a OR=1.80, 95% CI: 1.01-3.20), and the type of primary sexual partner in the last six months being a casual sexual partner (a OR=1.50, 95% CI: 1.26-1.80). Conclusions:The characteristics of MSM with different types of primary sexual partners are different, and the proportion of HIV testing still needs to be improved. In the future, we should make full use of the Internet and peer education to expand the coverage of HIV testing for MSM, targeting the characteristics of MSM with different types of primary sexual partners.

Objective:To analyze the status of first viral load (VL) suppression for newly diagnosed HIV/AIDS on antiretroviral therapy (ART) from 2014 to 2016 in Shandong province, to provide theoretical evidence for improvement of ART effectiveness.Methods:Based on a retrospective cohort study, logistic regression model was used to identify influencing factors about VL suppression.Results:There were 4 833 newly diagnosed HIV/AIDS cases who received ART from 2014 to 2016 in Shandong province, and 3 449 cases achieved VL suppression at the first VL testing. The rate of first VL suppression was 71.36%. The possibilities of first VL suppression among patients on ART with education at junior high school, junior college and above were higher than those with education at primary school and below, with OR values at 1.75 and 2.00, separately. The possibilities of first VL suppression for patients treated at medical institutions was higher than those by CDC, with OR value 1.29. The possibilities of first VL suppression among patients whose CD4 count level at 201-350, 351-500 and ≥501 cells/μl were higher than that of the patients whose CD4 count level at ≤200 cells/μl, with OR values at 2.36, 2.11 and 2.66, respectively. The possibilities of first VL suppression among patients who missed doses was lower than those who did not miss doses, with OR value at 0.55. All the Pvalues for the above comparisons was <0.05. Conclusions:The suppression of viral load for HIV/AIDS on ART was influenced by culture level, CD4 count level at the entry of ART, treatment institutions and adherence to the therapy. Earlier diagnosis, treatment services provided by medical institutions and improvement of drug adherence can enhance ART effectiveness.

Objective: To analyze the epidemiological characteristics of HIV/AIDS infected students in Shandong Province, to provide a basis for the prevention and control of AIDS transmission in the student population. Methods: All 863 HIV/AIDS students cases during 2010-2019 were collected in Shandong Province. Epidemiological characteristics was described and the trends in the 10 years since 2010 was analyzed. Results: These 863 HIV/AIDS students were mainly transmitted through homosexual sex (763 cases, 88.41%), and the samples were mainly from voluntary consultation testing (433 cases, 50.17%). From 2010 to 2019, the proportion of student cases in the total number of cases showed an increasing trend ( χ 2 trend =30.21, P <0.01). Among them, the proportion of homosexual transmission cases increased year by year ( χ 2 trend =6.35, P =0.01), the proportion of cases aged 18-22 years increased year by year ( χ 2 trend =6.10, P =0.01), the proportion of cases with college degree or above increased year by year ( χ 2 trend =4.26, P =0.04). At present, voluntary consultation testing were the main source.There was no significant difference between the years of sample sources ( χ 2 trend =2.97, P =0.09). Conclusion The report number of students in Shandong Province are on the rise in recent years, especially those infected by same sex transmission, mainly with high education background, which calls for targeted strategies and intervention measures.
