Objective To investigate the changes of fractional exhaled nitric oxide (FENO)) and their relation with lung function in bronchial asthma.Methods FENO and forced expiratory volume in the first second (FEV1) were measured during the periods of acute onset,chronic persistence and paracmasis in 54 patients with asthma and 19 healthy persons.Results There were significant differences in the levels of FENO and FEV1 among the course of acute onset [(57.59 ± 32.24) ppb and (1.72± 0.33) L],chronic persistent course [(40.02 ± 15.68) ppb and (2.41 ± 0.23) L],paracmasis [(26.71±6.07) ppb and (2.82±0.29 )L]and control[(14.74±3.42 ) ppb and (2.93±0.13)L] (F=19.555,163.096,P＜0.01) except for the levels of FEV1 between paracmasis and control group(P＞0.05).The negative correlation between FENO and FEV1 was found in the course of acute onset(r=- 0.666,P =0.005 ),but not in the chronic persistent course ( r =- 0.288,P =0.176) and paracmasis(r=-0.246,P=0.457).Conclusions The level of FENO is increased and may be useful to evaluate control degree in patients with asthma.

Objective:to do clinical study on effect of sleep-related behavior modification and relaxation training on insomnia.Method:44 outclinic patients with insomnia received sleep-related behavior modification and relaxation training for 8 weeks. Using self-designed inventory to assess the outcome.Result:the time of sleep increased since the third week, and increased continuously. After the intervention, the rate of satisfaction about sleep increased from 23% at the baseline to 86.1%. 36 of the 44 patients completed the 8-week clinical study. Conclusion:sleep-related behavior modification and relaxation training can improve sleep of patients with insomnia.

Objective To explore the efficacy of comprehensive community-based rehabilitation on chronic schizophrenia and assess in the view of health economy. Methods 80 chronic schizophrenic patients accepted comprehensive community-based rehabilitation for 1 year and were followed up for 1 year. Other 80 chronic schizophrenics were as the controls. They were observed with outcome and the cost. Resultsn The social function, compliance, stability rate, burden on family caregiver, satisfaction of living, psychiatric symptoms, hospitalization were all better in the rehabilitation group than in the control group (P<0.01), and the total cost in the 2 years was less, especially that on hospitalization,maintenance treatment, work loss of caregivers, public prevention (P<0.01). Conclusion Comprehensive community-based rehabilitation can improve the outcome of chronic schizophrenics with less cost.

Objective To explore the influential factors on the medication compliance of patients with cancer pain, so as to provide the basis for improving the medication compliance .Methods Thirteen patients with cancer pain were surveyed by the semi-structured interview , and the data were analyzed by the Colaizzi phenomenological analysis .Results The influential factors on the medication compliance of patients with cancer pain were classified into three themes through interviews:the patient's own factors;the effect of social and family support system;and the effect of support factors on health information needs .Conclusions We should strengthen targeted health education and psychological nursing , and bring the family and social support systems into full play, and establish a good nurse-patient relationship , and pay attention to health information demands of patients in order to improve medication compliance of patients with cancer pain .

Objective:To understand the use of post-exposure prophylaxis (PEP) and analyze related factors among men who have sex with men (MSM) in Qingdao, and provide a reference for the AIDS prevention and control in this population.Methods:A cross-sectional survey conducted from April 2022 to February 2023. Relying on MSM social groups in Qingdao, a snowball sampling method was applied to recruit research subjects who met the inclusion criteria of age ≥18 years old, having had homosexual anal or oral sex in the past six months, and HIV-negative or infection status unknown. The sample size was estimated at 566. Data on demographic characteristics, sexual behavior characteristics, PEP use, and others of the research subjects was collected through on-site questionnaires. The logistic regression model was used to analyze the factors associated with using PEP.Results:A total of 811 participants were recruited, mainly aged 25-34 (53.6%, 435/811), unmarried (74.7%, 606/811), with an average monthly income of ≥5 000 yuan (52.2%, 423/811), and having lived in Qingdao for ≥10 years (75.6%, 613/811). The proportion of those who knew the HIV status of their sexual partners in the last six months was 67.1% (544/811), and those with HIV-positive partners were 3.6% (29/811). In the last six months, the proportion of participants who had group sex (86.4%, 701/811), unprotected anal sex (98.2%, 796/811), and use of club drugs (80.3%, 651/811) was high. Moreover, 28.4% (230/811) had used PEP. The multivariate logistic regression analysis showed that the factors related to the use of PEP included divorced or widowed (a OR=5.46,95% CI:1.96-15.17), average monthly income ≥5 000 yuan (a OR=2.04,95% CI:1.44-2.89), same-sex sexual orientation (a OR=0.40,95% CI:0.22-0.71), having HIV-positive sexual partners in the last six months (a OR=2.54,95% CI:1.13-5.71) and having been tested for HIV ≥3 times in the last six months (a OR=1.46,95% CI:1.04-2.06). Conclusions:The prevalence of risk behaviors among MSM in Qingdao was high, and the use of PEP was low. In the future, it is essential to increase HIV/AIDS prevention education among MSM, promote MSM to know the HIV status of their sexual partners, and reduce the prevalence of risk behaviors among this population. Additionally, explore medical insurance reimbursement plans for PEP to reduce utilization costs and promote the use of PEP by MSM after HIV exposure occurs as soon as possible.
