Aim To compare the protective effects of gastrodin and melatonin on methamphetamine ( MA )-induced neurotoxicity of cortical neurons. Methods Cortical neuron cells were treated with different concentrations of methamphetamine for 24 h, then the cell viability was detected by CCK-8 kit to choose the optimal concentration of MA. The cells were treated with different concentrations of gastrodin or melatonin 2 h before the treatment of cells with optimal concentration of MA for 24 h. The optimal concentrations of gastrodin and melatonin were determined by CCK-8 kit as well. Cortical neuron cells were randomly divided into con trol group, MA group, gastrodin plus MA group, and melatonin plus MA group. Then the apoptotic rate of cells was detected by TUNEL method . The expression of Caspase-3 in cells was assessed by immunofluorescence. Results The optimal concentration of MA was 0. 5 mmol • L"1. After treating with MA, the numbers of cortical neurons decreased, the length of synapses became shorter, and the cell vacuolation, the number of dead cells increased. The optimal concentration of gastrodin was 25 mg • L'1, and the optimal concentration of melatonin was 10 jimol • L"1. Gastrodin treatment could reduce the apoptosis of cortical neurons induced by MA, and the expression of Caspase-3 decreased as well, and there was no significant difference compared with the intervention effect of gastrodin with melatonin. Conclusions MA has neurotoxic damage to cortical neurons. Gastrodin could attenuate MA-in-duced neurotoxicity via alleviating the apoptosis induced by MA.

OBJECTIVETo compare the clinical effective differences between acupuncture-moxibustion and Chinese herbs for functional dyspepsia with emotional disorder.

METHODSEighty patients were randomly divided into an observation group and a control group, 40 cases in each one. In the observation group, based on the basic treatment Zusanli (ST 36), Yinlingquan (SP 9), Zhongwan (CV 12), Danzhong (CV 17), Neiguan (PC 6), Taichong (LR 3), Ganshu (BL 18), Geshu (BL 17) and Danshu (BL 19) were selected once every day or every other day. The treatment was given 14 times. In the control group, based on the basic treatment individual therapy of Chinese herbs according to syndrome differentiation was applied,one dose a day. Patients were treated for 4 weeks in the two groups. The scores of self-rating depression scale (SDS), the main symptoms and satisfied degree by self-rating for treatment were observed before and after 4-week treatment in the two groups. Also, the rate and the average time of return visit were compared in 6 months after treatment. Results After treatment, the SDS scores and the main symptoms scores were all improved compared with those before treatment in the two groups (all P< 0. 05). After 4-week treatment, the improvement of the SDS score in the observation group was better than that in the control group (48. 9±8. 5 vs 53. 1±8. 0, P<0. 05). After 1-week treatment and 4-week treatment, the improvements of the main symptoms in the observation group were superior to those in the control group (2. 7 ± 1. 0 vs 3. 3±0. 9, 1. 5±0. 9 vs 2. 3±1. 1, both P<0. 05), and the satisfied degree scores by self-rating were better than those in the control group (3. 0±1. 1 vs 3. 8±1. 3, 2. 0±1. 4 vs 2. 9±1. 5, both P<0. 05). In 6 months after treatment,the return visit rate in the observation group was 42. 5% (17/40), and it was lower than 70. 0% (28/40) in the control group (P<0. 05). The average time of return visit in the observation group was less than that in the control group (1. 0±0.8 vs 1. 9±0. 7, P<0. 05).

CONCLUSIONThe effect of acupuncture-moxibustion or functional dyspepsia with emotional disorder is better than that of Chinese medicine.

OBJECTIVETo investigate the effect of histone deacetylase inhibitor suberic bishydroxamate (SBHA) on human acute myeloid leukemia (AML) cell lines.

METHODSAML U937, KG-1 and Kasumi-1 cells were treated with SBHA. Cell growth was measured by MTT assay. Apoptosis was determined using flow cytometry. Activation of Caspase pathway and expression of apoptosis regulator proteins were detected by Western blot.

RESULTSSBHA significantly induced growth arrest and apoptosis in U937, KG-1 and Kasumi-1 cells. Enhanced apoptosis was observed in SHBA group evidenced by strong activation of Caspase-9, Caspase-8 and Caspase-3. SHBA treatment resulted in down-regulation of anti-apoptotic protein Bcl-2 and Bcl-xl expression; down-regulated expression of antiapoptotic proteins survivin, XIAP and cIAP was also detected after SBHA treatment.

CONCLUSIONSBHA can effectively kill AML cells by inhibiting cell growth and inducing apoptosis, which is associated with the activation of Caspase pathway and regulation of apoptotic related proteins.

Objective　To investigate the drug resistance of Enterobacter cloacae isolated from blood samples in 75 member units of the Bacterial Drug Resistance Monitoring Network in Hebei, 2016- 2021, so as to provide a basis for rational drug use in clinic. Methods　WHONET 5.6 software was used to retrospectively analyze drug susceptibility of Enterobacter cloacae isolated from 32 secondary hospitals and 43 tertiary hospitals. SPSS19.0 software was used for statistical analysis. Results After removing the duplicate strains, 1 225 strains of E. cloacae were isolated from blood samples of 75 hospitals during 6 years, including 157 strains from secondary hospitals and 1 068 strains from tertiary hospitals. In this study, the resistance of Enterobacter cloacae to 16 kinds of antibiotics was analyzed. The drug resistance rates to cefuroxime (52.4%-67.8%), piperacillin (27.4%-31.2%), ceftazidime (27.8%-35.5%), ceftriaxone (29.5%-45.0%), aztreonam (22.2%-32.3%), cotrimoxazole (21.6%-28.7%) were higher; the resistance rates to amikacin and tobramycin were lower than 15.0%. The resistance rates to imipenem and meropenem were 3.6%-12.3% and 5.1%-11.4%, respectively. The resistance rate to ciprofloxacin in tertiary hospitals was 22.4%, and the resistance rate to cotrimoxazole was 23.9%. Except for these two antimicrobials, the resistance rates to other antimicrobial drugs in tertiary hospitals were higher than that in secondary hospitals. A total of 121 carbapenem-resistant Enterobacter cloacae strains were detected in the past 6 years, with an increasing detection rate (χ2trend=6.305, P=0.012). Conclusions　Enterobacter cloacae has great differences in antimicrobial resistance to different antibiotics, and is sensitive to carbapenems. The drug resistance in tertiary hospitals is generally higher than that in secondary hospitals. Drug resistance monitoring and drug resistance mechanism research should be strengthened to better guide clinical drug use and curb the rise of drug resistance.
