Objective:To explore the latent profile types of capability-opportunity-motivation-behavior in stroke patients and analyze the influencing factors of different latent profiles.Methods:From January to October 2023, totally 596 stroke patients from the Neurology Department of five ClassⅢ Grade A hospitals in Henan Province were selected by stratified random sampling. The patients were surveyed using a general information questionnaire, the Stroke Prevention Knowledge Questionnaire (SPKQ), the Social Support Rating Scale (SSRS), the WHO's Quality of Life Questionnaire- Brief Version (WHOQOL-BREF), the Short Form Health Belief Model Scale (SF-HBMS), and the Health Promoting Lifestyle ProfileⅡ (HPLPⅡ). Latent profile analysis was used to classify the capability-opportunity-motivation-behavior characteristics of stroke patients, and multiple logistic regression was conducted to explore the influencing factors of different latent profiles.Results:Three latent profiles of capability-opportunity-motivation-behavior in stroke patients were identified, including low capability-opportunity-motivation-behavior with high health beliefs (32.4%, 193/596), moderate capability-opportunity-motivation-behavior with insufficient health beliefs (47.5%, 283/596), and high capability-opportunity-motivation-behavior with lack of social support (20.1%, 120/596). Multiple logistic regression analysis showed that educational level, smoking history, family history, body mass index, and Charlson Comorbidity Index score were influencing factors of different latent profiles ( P<0.05) . Conclusions:Stroke patients exhibit distinct classifications of capability-opportunity-motivation-behavior. Targeted interventions should be conducted based on the characteristics of each category to improve health behavior management outcomes in patients.

Objective To investigate the clinical efficacy and safety of 1 565 nm non-ablative fractional laser combined with topical minoxidil and oral finasteride in the treatment of patients with androgenetic alopecia(AGA).Methods Seventy-five male AGA patients with Norwood-Hamilton classification grade Ⅱ-Ⅲ,were randomly assigned into three groups:the control group 1,the control group 2 and the experimental group,with 25 cases in each group.Patients in the control group 1 received topical 5%minoxidil(1 mL,twice daily).Patients in the control group 2 were treated with both topical 5%minoxidil and oral finasteride(1 mg,once daily).Patients in the experimental group received a combined therapy of 1 565 nm non-ablative fractional laser in addition to topical 5%minoxidil and oral finasteride.Hair overall efficacy was evaluated using a 7-point rating scale after 24 weeks of treatment.Hair diameter and density were measured using a dermoscope.Patient satisfaction was assessed post-treatment,and adverse reactions were recorded.Results The overall efficacy of hair in the experimental group was superior to the control group 1 and the control group 2.There were no significant differences in hair density and hair diameter before treatment between the three groups(P＞0.05).After treatment,hair diameter and density increased in all three groups compared to baseline values(P＜0.05),and the hair diameter and hair density of the experimental group were higher than those of the control group 1 and the control group 2(P＜0.05).Patient satisfaction in the experimental group was higher than that in the control group 1 and the control group 2(P＜0.05).Patients in the experimental group experienced tolerable pain and burning sensations during laser treatment,and the symptoms were self-alleviated within a few hours.There were no serious adverse reactions reported in any group.Conclusion The combination therapy of 1 565 nm non-ablative fractional laser,5%minoxidil,and finasteride demonstrates significantly better efficacy in the treatment of AGA than minoxidil and finasteride alone drug therapy.

【Objective】 To analyze the situation of regular whole blood donation in Tianjin between 2013 and 2022, in order to provide data support for improving the recruitment and retention measures of regular blood donors and ensuring safe clinical blood supply. 【Methods】 From 2013 to 2022, 185 639 regular whole blood donors in Tianjin were selected as the study group and 1 015 312 other whole blood donors in the same period were selected as the control group. The demographic data, blood collection volume and blood retest screening of blood donors in the two groups were statistically analyzed. 【Results】 The number of regular blood donors and the volume of blood donated in Tianjin increased year by year from 2013 to 2022, with an average annual growth rate of 6.22% and 6.18%, respectively. From 2013 to 2021, the retention rate of regular blood donors increased first and then decreased. The proportion of male blood donors in the study and control groups showed a decreasing trend but the proportion of female donors showed an increasing trend, with the proportion of male donors in the study group higher than that in the control group and the proportion of female donors lower than that in the control group (both P<0.05). In the study group, the majority of blood donors were in the age of 26-35 years old, followed by those of 36-45 years old; in the control group, the majority of blood donors were in the age of 18-25 years old, followed by those of 26-35 years old; the proportion of blood donors in the study group in the age of 18-25 years old was lower than that in the control group, while the proportion of blood donors of other age group was higher than that in the control group, and the difference was statistically significant (P<0.05). The rates of 200 mL and 300 mL blood donations and insufficient blood donations in the study group were lower than those in the control group, while the rate of 400 mL blood donations was higher than that in the control group, and the differences were statistically significant. Among the blood donors in the study group, the proportion of students, civil servants, medical workers, military personnel, teachers and others was lower than that of the control group, while the proportion of the rest occupations was higher in the study group than that of the control group, and the differences were all statistically significant. There was a significant difference in the proportion of regular blood donors among blood donors of different professions. The re-test deferral rates of ALT and anti-TP in the study group showed a decreasing trend followed by an increasing trend, and the re-test deferral rates of HBV, HCV and HIV showed an increasing trend followed by a decreasing trend, and all the re-test deferral rates in the study group were lower than those in the control group, and the differences were statistically significant (P<0.05) . 【Conclusion】 From 2013 to 2022, the situation of regular blood donors in Tianjin has a certain regularity, and there is certain room for growth. Precise recruitment strategies targeting different populations should be adopted to have more regular blood donors.

ObjectiveTo analyze the effect of different fixation methods on the chemical quality characteristics and antioxidant activity of Rehmannia glutinosa leaves， so as to lay a foundation for the selection of processing technology and quality evaluation of this medicinal materials. MethodR. glutinosa leaves was dried at 55 ℃ after treating by three fixation methods （55 ℃， boiling water， 105 ℃）， and then the fingerprints of R. glutinosa leaves were collected by high performance liquid chromatography （HPLC） and near infrared spectroscopy （NIRS）， and their antioxidant activities were analyzed by the 2，2-biphenyl-1-picrylhydrazyl （DPPH） method. Finally， similarity analysis， principal component analysis （PCA）， orthogonal partial least squares-discriminant analysis （OPLS-DA） and Pearson correlation analysis were used to comprehensively evaluate the quality of R. glutinosa leaves with different fixation methods. ResultThe results of HPLC and NIRS fingerprint analysis indicated that there were differences in the quality characteristics of R. glutinosa leaves by different fixation treatments. The comprehensive score of chemical quality of R. glutinosa leaves by fixation at 55 ℃ was the highest， its average comprehensive score was 2.096， followed by fixation at 105 ℃， and the lowest was fixation with boiling water. The antioxidant activity of sample with fixation at 55 ℃ was the highest， followed by fixation with boiling water. The results of OPLS-DA showed that verbascoside， isoacteoside and catalpol were the main components causing the difference in chemical quality of the leaves from the three treatments， and the three components were positively correlated with the antioxidant activity of R. glutinosa leaves. Among them， the correlation between verbascoside and antioxidant activity was extremely significant， and the isoacteoside was significant. ConclusionThe chemical quality and antioxidant activity of R. glutinosa leaves are affected by the method of fixation， and the fixation at low temperature is the best primary processing method of R. glutinosa leaves.

【Objective】 To investigate the basic situation of blood donation given by university students in Tianjin and provide data to support the sustainable development of college blood donation. 【Methods】 The group blood donation in Tianjin universities from 2012 to 2021 was enrolled as the study group and other whole blood donors in the same period as the control. The statistical analysis of the two groups was conducted. 【Results】 From 2012 to 2021, the number of college blood donations in Tianjin increased from 8.93% to 21.32%, with the average annual growth rate of 12.80%, and the units of blood donated increased from 5.44% to 18.82%, with the average annual growth rate of 17.06%. The repeat donation rate in the study group was significantly lower than that of the control(20.74% vs 25.47%, P<0.05). In 2012, the specification of blood donated by college students were mainly 200 mL(87.38%), then in 2021, gradually transitioned to 400 mL(38.77%), followed by 200 mL(35.19%) and 300 mL(26.03%). The rates of 200/300 mL donation and insufficient blood donation in the study group were significantly higher than those in the control, to the contrary, the rate of 400 mL donation was lower in comparison to the control, with statistically significant differences. The deferral rates of initial screening and ALT among college donors differed significantly over the decade: HBsAg showed a significant downward trend, while Hb increased significantly(P<0.05); the deferral items in the study group was significantly lower than the control(P<0.05), except Hb. During the retest period, the deferral rates of ALT and HBV were decreasing, which was the lowest in 2018 then bounced back slightly; the deferral rate of HIV showed a increasing tendency(P<0.05). The deferral rates of all retest items in the study group were lower than those in the control(P<0.05). In the study group, no significant differences were noticed in the deferral rates of retest items by genders, except for ALT and HCV, as males were higher than females. 【Conclusion】 College student groups are an important force in blood donation. A long-term mechanism should be established to safeguard this special group and to provide targeted health education and personalised services to promote the sustainable and healthy development of blood donation in universities.

【Objective】 To analyze the infection characteristics and prevalence of HIV among college group voluntary blood donors in Tianjin, China, so as to provide data support for improving the promotion and recruitment strategies of voluntary blood donors, ensuring the safety of blood for clinical use, and formulating HIV prevention and control strategies for adolescents. 【Methods】 The college donors with anti-HIV(+ ) and HIV RNA(+ ) results in Tianjin from January 1, 2012 to December 31, 2021 were selected and analyzed. The relationships among HIV positive rate(anti-HIV+ or HIV RNA+ ), solo anti-HIV positive rate(anti -HIV+ and HIV RNA-), solo HIV RNApositive rate(anti-HIV- and HIV RNA+ ) and double positive rate(anti-HIV+ and HIV RNA+ ) between different years, gender, residence status, age and blood donation history(primary or repeated blood donation) were counted. 【Results】 The HIV positive rate and solo HIV RNA positive rate of college group blood donors from 2012 to 2021 showed a trend with significant increasing(χ²=49.266, 71.379, P<0.05). The HIV positive rate in the controls was significantly higher than that in the college blood donors(χ²=92.414, P< 0.05). The HIV positive rate and solo anti-HIV positive rate showed no differences by genders, but the male presented significant higher positive rate in solo HIV RNA and double positive results than the females(χ²=6.059, 10.900, P<0.05). The HIV positive rate of local resident was significantly lower than those nonlocal students(χ²=47.523, P<0.05). The HIV positive rate differed significantly by ages, with the highest at the age of 18 and the lowest at the age of 21(P<0.05). The difference of HIV double positive rates between the first-time and repeated donors was marginal, while the other three positive rates in thefirst-time donors were significantly higher than those in the repeated donors (P<0.05). 【Conclusion】 In recent years, the HIV positive rate and solo HIV RNA positive rate of college group blood donors present an increasing tendency. The consultation and education on HIV-related issues should be strengthened among college students during blood donation publicity, so as to ensure the safety of blood use and prevent the spread of AIDS in schools.

Objective:To investigate the present situation of unintended pregnancy within two years postpartum and its influencing factors in China.Methods:Participants who delivered a live birth at 60 hospitals in 15 provinces in the eastern, central and western regions of China during July 2015 to June 2016 were interviewed by using structured questionnaire. Information on occurrence of unintended pregnancy within 2 years after delivery, postpartum contraceptive use, sexual resumption, breastfeeding, and women′s socio-demographic characteristics, and so on, were collected. Life-table analysis, cluster log-rank tests and a 2-level Cox regression model were used for data analysis.Results:A total of 18 045 postpartum women were investigated. The cumulative 1- and 2-year unintended pregnancy rates after delivery were 5.3% (95% CI: 4.5%－6.1%) and 13.1% (95% CI: 11.3%－14.8%), respectively. Cox regression model analysis showed that the risk of unintended pregnancy within 2 years postpartum were increased in younger women, ethnic minorities, women with abortion history, and those who had a vaginal delivery with short lactation time and late postpartum contraceptive initiation (all P<0.01). The risk of postpartum unintended pregnancy was not associated with geographic regions and hospitals where women gave a birth (all P>0.05). Conclusions:In China, the risk of unintended pregnancy within 2 years after delivery is relatively high. Service institutions and service providers should improve the quality of postpartum family planning services, promote the use of high effect contraceptive methods, and educate women to use a method at the time of their sexual resumption or even before.
