BACKGROUND:At present,most general hospitals in China treat patients with neurosis and mental diseases merely by means of clinical psychological consultation,which cannot meet the requirements of social service for metal disorders. Is it feasible to establish open psychology wards?OBJECTIVE:To investigate the feasibility of establishing open psychology ward in general hospitals for patients with neurosis and mental diseases.DESIGN:Case analysis based on patients.SETTING:Department of Psychology of Guangdong Medical College Affiliated Hospital.PARTICIPANTS:Totally 900 patients with various types of neurosis were admitted to the Department of Psychology of Guangdong Medical College Affiliated Hospital between July 2000 and March 2003.There were 688 patients with different kinds of psychoneurosis and112 cases of mental diseases. Of them,there were 523 men and 377women aged from 11 to 80 years.with the mean age of (42±8) years and hospitalization duration of(17.0±6.5) days.METHODS:Open management consisting of open ward,supporting system,humanized restriction,collective physical exercise and psychological support was adopted.Symptom checklist (SCL-90) was used by trained psychological doctors to assess the therapeutic effects in the 900 patients with neurosis and mental diseases after two-month rehabilitation.Meanwhile,169 patients with depression were examined with Hamilton rating scale for depression(HAMD) at 2,4,8 weeks of treatment.patients.RESULTS:Open psychology ward could provide an environment for patients to live and make free contact with the outside world. Of the 900patients with various neurosis and metal diseases,531 (59.0%) had recovery to normal,264(29.4%) had obvious improvement,81(9.0%) had improvement,and 24 (2.6%) had no therapeutic effect,with the total effective rate of 97.4% .None of the patients had any accident. HAMD score of the 169 patients with depression was (32.3±3.6) before treatment,was obviously lower at 2,4 and 8 weeks of treatment [(17.4±4.2),(11.5±4.8) and(5.8±3.6),respectively](P ＜ 0.01).CONCLUSION:The therapeutic effect of the open psychology ward in the general hospital on various neuropathies and mental diseases was 97.4% in the 900 cases,with no accident occurring during hospitalization.Depression of the 169 patients was obviously improved,indicating that it isfeasible to establish open psychology ward in general hospitals.

OBJECTIVE:To provide reference for rational use of antibiotics in the clinic of our hospital. METHODS:Drug re-sistance of Gram-negative bacillus in the inpatients of our hospital were analyzed retrospectively during May 2013-Dec. 2015 as well as the situation of producing metallo-β-lactamase(MBLs). RESTUTS:A total of 2089 strains of Gram-negative bacillus were detected in our hospital during 2013-2015,among which there were 1456 strains of enterobacteria (69.70%) and 633 strains of non-fermentative bacteria,mainly involving Escherichia coli,Pseudomonas aeruginosa,Klebsiella pneumoniae,Acinetobacter bau-mannii and Enterobacter cloacae. A total of 406 strains of carbapenems-resistant bacteria were detected (19.44%),including 367 strains of non-fermentative bacteria and 39 strains of enterobacteria. The resistant rates of carbapenems-resistant strains to 16 antibi-otics were all higher than 50%,but those of non-carbapenems-resistant strains were in relative low level. Except for aztreonam,re-sistant rates of carbapenems-resistant strains to other 15 antbiotics were all higher than those of non-carbapenems-resistant strains, with statistical significance(P<0.05). A total of 36 strains of producing MBLs were detected(8.87%),including 13 strains of pro-ducing MBLs drug-resistant P. aeruginosa and 23 strains of producing MBLs drug-resistant A. baumannii;producing MBLs drug re-sistant enterobacteria had not been found. CONCLUSIONS:Gram-negative bacillus are mainly enterobacteria in our hospital;car-bapenems-resistant strains are mainly non-fermentative bacteria,resistant rate of them are commonly higher than that of non-drug-re-sistant strain. The situation of producing MBLs is serious,and enzyme producing strains are mainly non-fermentative bacteria. It is necessary to strengthen drug resistance of pathogen and enzyme producing strain monitoring,avoid the generation and spreading of drug-resistant strains due to irrational use of antibiotics.

The present study examined the protective effect of the ethanol extract of Sarcopyramis nepalensis (EESN) on agents-induced hepatotoxicity in mice and the possible mechanism. Acute liver injury was induced by administration of either CCl(4) or D-GalN. The animals were divided into 5 groups in terms of different treatment: normal group, CCl(4) or D-GalN group, silymarin or bifendate group, low dose EESN group (10 mg/kg) and high dose EESN group (30 mg/kg). Liver function was evaluated by detecting the levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST). The oxidize stress markers were measured, including malondialdehyde (MDA), glutathione peroxidase (GSH) and superoxide dismutase (SOD). Liver tissues were histopathologically examined by hematoxylin-eosin (H&E) staining. The acute toxicity study revealed that there was no toxicity of EESN at the dose of 5 g/kg in mice. The levels of ALT and AST in serum, and the MDA level in live tissues were significantly increased and the activities of SOD and GSH substantially decreased in mice after CCl(4) or D-GalN treatment. These biochemical and oxidize stress markers were profoundly improved after treatment with EESN at different doses, which was similar to the results of silymarin or bifendate treatment. The histophathological examination revealed the significant improvement in the pathological changes of the liver in EESN-treated mice as compared to those in CCl(4) or D-GalN group. It was concluded that EESN possesses potential antioxidant and hepatoprotective properties and has therapeutic potential for liver diseases.
