ABSTRACT
Objective·To understand the current situation of psychotherapy applied and relevant personnel's working in psychiatric hospitals, and provide advice to facilitate and promote the integrated service team building of domestic mental health institutions and the industry development of psychological treatment. Methods·Ninety-six psychiatric hospitals in China were selected and self-compiled questionnaire was used during the investigation. The actual feedback was collected from 52 hospitals in 25 provinces. Results·① According to the classification criteria of ICD-10 mental disorder, patients mainly suffered from schizophrenia, schizotypal disorder and delusional disorder, followed by affective disorder, in the psychiatric hospitals. ② There were 50 (96.2％) hospitals with psychological outpatient clinics, and 37 (71.2％) hospitals were equipped with mental wards. ③ The main types of patients who came to the psychology department in the psychiatric hospitals were emotional disorders, neurosis, stress-related and physical form disorders. ④ The composition of psychotherapists was 6 physicians, 2 clinical psychologists, and 1 nurse. ⑤ The top five psychotherapy techniques used by the psychiatric hospitals were cognitive therapy, supportive psychotherapy, behavioral therapy, group therapy, and family therapy. ⑥ 44.2％ of the practitioners working in this filed thought that the income had been too low if they only engaged in psychological treatment. Conclusion·In the staffing of mental health agency, compared to previous studies, the number of the psychology specialists increases, but it still makes up a small percentage, which does not match the needs of outpatient and ward patients. Psychological practitioners who rely on psychological treatment alone are in a lower income, and the gap between the expected income and actual income is too large. Government, health administration departments and hospitals should provide more support to psychological services and promote the development of institutions and personnel.
ABSTRACT
It is proved that polydatin has cardioprotection against ischemia-induced arrhythmia, but the electrophysiological mechanism is not clear. The aim of the present study was to investigate the effect of polydatin on action potential (AP) in ventricular papillary muscle and the underlying ionic mechanism in rat using intracellular recording and whole-cell patch clamp techniques. The results showed: (1) In normal papillary muscles, polydatin (50 and 100 µmol/L) shortened duration of 50% repolarization (APD(50)) and duration of 90% repolarization (APD(90)) in a concentration-dependent manner (P<0.01). But polydatin had no effects on resting potential (RP), overshoot (OS), amplitude of action potential (APA) and maximal rate of depolarization in phase 0 (V(max)) in normal papillary muscles (P>0.05). (2) In partially depolarized papillary muscles, polydatin (50 µmol/L) not only shortened APD(50) and APD(90) (P<0.05), but also decreased OS, APA and V(max) (P<0.05). (3) After pretreatment with glibenclamide (10 µmol/L), an ATP-sensitive K(+) channel blocker, the electrophysiological effect of polydatin (50 µmol/L) was partially inhibited. (4) Pretreatment with N(G)-nitro-L-arginine methyl ester (L-NAME, 1 mmol/L), a nitric oxide (NO) synthase inhibitor, failed to abolish the effect of polydatin (50 µmol/L) on AP. (5) Polydatin (25, 50, 75 and 100 µmol/L) decreased L-type Ca(2+) current in ventricular myocytes in a concentration-dependent manner (P<0.05). (6) Polydatin (50 µmol/L) increased ATP-sensitive K(+) current in ventricular myocytes (P<0.05). The results suggest that polydatin can shorten the repolarization of AP in normal papillary muscle and inhibit AP in partially depolarized papillary muscle, which might be related to the blocking of L-type Ca(2+) channel and the opening of ATP-sensitive K(+) channel.
