Objective: To optimize the ultrahigh pressure extraction ( UPE) process for forsythoside from Forsythia suspensa by Box-Behnken experimental design. Methods:On the basis of single factor screening, a three-factor and three-level Box-Behnken ex-perimental design was employed with liquid/material ratio( X1 ) , extraction pressure ( X2 ) and extraction time ( X3 ) as the independent variables. The response variable was the extraction yield of forsythoside. Results:The optimal UPE conditions for forsythoside were as follows:the ratio of solvent to material (ml·g-1) was 70, the extraction pressure was 151 MPa, and the extraction time was 114 s. With the optimal extraction process, the extraction yield of forsythoside was 13. 15 mg·g-1 . Conclusion:As a novel extraction tech-nology for Chinese herbal medicines, UPE procedure has higher extraction yield, lower extraction temperature, shorter extraction time and less power consumption, which provides a brand-new method for the extraction of forsythoside from Forsythia suspensa.

Objective:To investigate the efficacy and safety of bronchoscopic lavage in children with severe adenoviral pneumonia.Methods:Patients with severe adenovirus pneumonia who were admitted to ICU department of Hunan Children′s Hospital for bronchoscopy were collected from February to June 2019 and divided into lavage group( n=36) and non-lavage group( n=15) in line with whether lavage was performed.Their results, namely, bronchoscopic diagnosis, blood gas analysis before and 2 hours, 24 hours and 48 hours after bronchoscopy, improvement time of clinical symptoms(fever and pulmonary moist rales), the positive rate of pathogen detection and mortality rate, main vital signs such as heart rate, respiratory rate, mean arterial pressure and bronchoscopy-related complications were recorded before and 1 hour, 2 hours and 24 hours after bronchoscopy. Results:A total of 51 children were collected, all of whom suffered from endobronchitis.More secretions were observed in the airways of 36 patients in the lavage group, and only a little or no secretions were observed in 15 patients in the non-lavage group.P/F value and PCO 2 at 2 hours, 24 hours and 48 hours after treatment in the lavage group were improved comparing to those before treatment and were superior to those in the non-lavage group( P<0.05). P/F values at 24 hours and 48 hours after treatment in the non-lavage group increased and PCO 2 decreased at 48 hours after treatment( P<0.05). The thermal duration, time to resolution of moist rales in the lungs in the lavage group were shorter than those in the non-lavage group( P<0.05). The mortality rate in the lavage group was lower than that in the non-lavage group[2.8%(1/36) vs.26.7%(4/15), P<0.05]. The positive rate of pathogen detection in lavage group was higher than that in non-lavage group[55.6%(20/36) vs. 20.0%(3/15), P<0.05]. There was no significant difference in heart rate, respiratory rate, and mean arterial pressure at each time point before and after bronchoscopic treatment( P>0.05). Associated complications were 11 cases of intraoperative transient hypoxemia, four cases of bronchial mucosal bleeding, and one case each of postoperative hypoxemia, intraoperative hypertension and hypotension.There was no significant difference in the incidence of complications between the two groups( P>0.05). Conclusion:Bronchoscopic lavage, in treating children with severe adenovirus pneumonia, may improve clinical symptoms, respiratory function, and rate of pathogen detection, reduce mortality, and is effective and safe.

OBJECTIVETo understand the incidence of drop out of antiretroviral therapy (ART) in people living with AIDS/HIV and related factors in Nanjing, Jiangsu province, and Yuncheng, Shanxi province.

METHODSRetrospective cohort analysis was conducted. The cumulative incidence curves of drop out of ART, mortality and drug withdrawal were drawn with Kaplan-Meier method. The related factors were identified with Cox proportional hazards regression model.

RESULTSA total of 1 006 patients were included in Yuncheng, the median length of ART follow-up was 49.59 months (QR: 20.02-92.84), and 976 patients were included in Nanjing, the median length of ART follow-up was 19.93 months (QR: 11.48-34.07). The cumulative incidence of drop out of ART at 3 months, 6 months, 1 year, 2 years, 4 years, 8 years after ART was 8.19%, 9.23%, 11.08%, 13.75%, 17.74%, 27.66% in Yuncheng, and 3.01%, 5.17%, 7.47%, 10.97%, 17.45%, 28.72% in Nanjing respectively. Age, marital status, infection route, baseline CD4 cell count, the clinical stage classified by WHO at the end of the observation were correlated with the drop out of ART.

CONCLUSIONIn order to reduce the drop out of ART among people living with AIDS/HIV, it is necessary to conduct effective interventions targeting the patients with young age, the patients who divorced/widowed, the patients who were intravenous drug users, the patients with higher CD4 cell count at the beginning of ART and clinical stage III or IV at the end of the follow-up and increase the coverage of HIV test.

OBJECTIVETo understand the economic burden caused by antiretroviral treatment for people living with HIV/AIDS and influencing factors in Nanjing.

METHODSPeople living with HIV/AIDS were divided into two groups, HIV infected patients and AIDS patients. The data about their direct medical expenditure, direct non-medical expenditure and indirect economic loss in the past year were collected. Univariate and multivariate analysis were conducted to identify the potential influencing factors.

RESULTSThe median of direct medical expenditure and total costs for 133 HIV infected patients were 1,200 yuan RMB and 1,972 yuan RMB respectively. The median of direct medical expenditure and total costs for 145 AIDS patients were 1 060 yuan RMB and 2 826 yuan RMB respectively. The differences in direct medical expenditure and total costs between HIV infected patients and AIDS patients showed no statistical significance. The results from univariate analysis indicated that the sample source influenced total costs significantly. Multivariate analysis showed that onset time and CD level were negatively correlated with direct medical expenditure. The patients infected through heterosexual contact had more direct medical expenditure than those infected through homosexual contact. The patients receiving HIV test in hospitals had more direct medical expenditure than those receiving volunteer counseling and testing.

CONCLUSIONFurther efforts should be made to expand HIV testing and treatment coverage in order to detect HIV infections as early as possible. Early antiretroviral treatment should be given to HIV infected patients to maintain their immunity and reduce their medical expenditure.
