Stereochemical insights into neuroprotective alkaloids from the aerial parts of Emilia sonchifolia.

A new alkaloid featured with a dibenz[c,e]azepin-5-one scaffold, namely emililactam A (3), together with a known pyrrolidine alkaloid (emilisonchine, 1) and a known flavonoid alkaloid [8-(2″-pyrrolidinone-5″-yl)-quercetin, 2] were isolated from the aerial parts of Emilia sonchifolia. Compounds 1 and 2 were isolated as racemic forms which were further separated, for the first time, to their corresponding enantiomers [(+)-1/(-)-1 and (+)-2/(-)-2], respectively, by using chiral-phase HPLC. The structure of new compound 3 was elucidated by extensive spectroscopic analysis.

A nomogram for predicting rectovaginal fistula after low anterior resection for rectal cancer.

Purpose: Rectovaginal fistula (RVF) is a complicated and troublesome complication of low anterior resection (LAR) for rectal cancer. We aimed to investigate the risk factors for post-LAR RVF and develop a predictive nomogram.

Methods: We performed a retrospective analysis of 821 female patients with rectal cancer who underwent LAR between October 2010 and October 2018.

Patient-doctor concordance of perceived mental health service needs in Chinese hospitalized patients: a cross-sectional study.

Background: To assess the subjective concordance on mental health service needs in hospitalized patients between patients and doctors in China.

Methods: A cross-sectional study was performed in one day. All hospitalized inpatients from selected departments of West China Hospital were recruited as potential participants.

Why is the recognition rate of psychological distress under-estimated in general hospitals? A cross-sectional observational study in China.

This study aimed to investigate the recognition rate of psychological distress in general hospitals in China and to examine the main associated factors.Using a cross-sectional study design, the questionnaires were administered to a total of 1329 inpatients from a tertiary hospital. The Patient Health Questionnaire-9 (PHQ-9), the Generalized Anxiety Disorder 7-item scale (GAD-7), the Patient Health Questionnaire (PHQ-15) and the Whiteley-7 (WI-7) were used to assess patients' mental health status.

Prevalence and strong association of high somatic symptom severity with depression and anxiety in a Chinese inpatient population.

Background: The prevalence of the high somatic symptom severity (HSSS) and its associations with sociodemographic factors, depression, and anxiety has not been surveyed in inpatient populations at general hospitals.

Methods: A sample including 1329 inpatients in a Chinese general hospital was surveyed using Chinese version of 15-item patient health questionnaire (PHQ-15), 9-item patient health questionnaire, and generalized anxiety disorder 7-item scale.

Results: A total of 27.

The development and validation of Huaxi emotional-distress index (HEI): A Chinese questionnaire for screening depression and anxiety in non-psychiatric clinical settings.

Background: Depression and anxiety among general hospital patients are common and under-recognized in China. This study aimed toward developing a short questionnaire for screening depression and anxiety in non-psychiatric clinical settings, and to test its reliability and validity.

Methods: The item pool which included 35 questions about emotional distress was drafted through a comprehensive literature review.

Impacts of semi-transparent window on reflectance from metallic gratings at oblique incidence.

This work both numerically and experimentally investigates the reflectance from the smooth side of a semi-transparent 508-µm-thick window with metallic gratings attached on the other side. The incident light is oblique and linearly polarized, and its wavelength ranges from 2.5 to 25 µm.

[Study on sustainable development of industy of ethnic medicine in minority area].

Ethnic medicine industry is facing many problems such as narrow market, exhaustion of resource, decline of ethnic medicine and no qualified successors. Sustainable development theory was utilized to analyse the elements and problems of ethnic medicine industry, and the counter measures were put forward to get rid of the predicament and to realize the sustainable development which depends on the ethnic medicine resources, national medicine, industrial policy, personnel training and modern technology. The development issues of ethnic medicine industry can be solved by the coordination of enterprise, government and public.
