OBJECTIVETo evaluate the effects of prenatal stress on neurological functions after middle cerebral artery occlusion (MCAO) in adult offspring rats.

METHODSPregnant rats were randomly assigned to prenatal stress treatment, which was exposed to restraint three times daily in the last week of pregnancy, and no prenatal stress treatment. Adult male offspring rats were subjected to transient focal cerebral ischemia by MCAO. They were randomly divided into four groups: sham group, prenatal stress + sham group, MCAO group and prenatal stress + MCAO group (n = 10). After 24 hours of reperfusion, the neurological deficits were evaluated. The infarct size, cell apoptosis and expression of Caspase 3, cleaved Caspase 3 and Bcl-2 were detected.

RESULTSCompared with MCAO group, the neurological deficits, infarct size and apoptotic cells in prenatal stress + MCAO group were increased significantly (all P < 0.05). The expressions of Caspase 3 and cleaved Caspase 3 were much greater in prenatal stress + MCAO group than those of MCAO group, while the expression of Bcl-2 was significantly decreased in prenatal stress + MCAO group compared with MCAO group (all P < 0.05).

CONCLUSIONPrenatal stress might exacerbate neuroloeical deficits in the offspring rats after MCAO by increasing cell apoptosis.

OBJECTIVETo explore action mechanism of electroacupuncture (EA) at "Fenglong" (ST 40) for treatment of hyperlipidemia.

METHODSForty SPF-grade SD rats were randomly divided into a normal group (group A), a model group (group B), a model diet-control group (group C), a model + EA group (group D) and model diet-control + EA group (group E), 8 cases in each one. The rats in group A were fed with normal diet continuously while those in the rest 4 groups were fed with high-fat diet to establish hyperlipidemia model. Afterwards, the rats in group C and group E were fed with normal diet, while EA at "Fenglong" (ST 40) was applied in group D and group E, 30 min per time, once a day. After 28 days of treatment, macrophage was collected in each group. Oil red O-staining was applied to detect the formation of foam cells, and enzyme-linked immunosorbent assay (ELISE) was adopted to measure the contents of total cholesterol (TC) in macrophage and analyze the rate of cholesterol efflux.

RESULTSThe counts of positive cells of oil red O-staining and the contents of TC in the group B, group C and group D were significantly increased compared with those in the group A (all P < 0.01). The counts of positive cells and contents of TC in the group C, group D and group E were significantly clecreased compared with those in the group B (all P < 0.01), and the decline in group D was more obvious than that in the group C (all P < 0.01). Compared with group C and group D, the counts of positive cells and contents of TC in the group E was obviously decreased (all P < 0.01), which was not statistically different from group A (P > 0.05). In the meantime, compared with group C, the rate of cholesterol efflux in group D and group E was significantly increased (both P < 0.01), and the rise in group E was more obvious than that in the group D.

CONCLUSIONThe electroacupuncture at "Fenglong" (ST 40) could significantly prohibit the transformation of macrophage into foam cell and increase rate of cholesterol efflux in macrophage, which could prevent and reverse the formation of foam cell and play an essential role in treating hyperlipidemia and stopping it from developing into a further level.

Objective : To understand the current situation and characteristics of narcotic drugs and psychotropic drugs abuse or dependence among hospital patients and to provide reference for strengthening the management of narcotic drugs and psychotropic drugs. Methods : We collected clinical data from hospitals in Shandong and Guizhou provinces in 2016 and selected patients with history of narcotic drugs and psychotropic drugs. We investigated them through telephone or face-to-face interview,then described the characteristics of demographic information and abuse or dependence of narcotic drugs and psychotropic drugs in diagnosed drug abusers. Results : A total of 280 patients with drug abuse or dependence were recruited,of which 223 cases from nine hospitals in Shandong and 57 cases from five hospitals in Guizhou. There were 170 male patients,accounting for 60.71%; 193 patients aged 45 years and above,accounting for 68.93%; 223 married patients,accounting for 80.51%; 166 patients with a education level of junior high school and below,accounting for 61.25%; 125 patients engaged in agriculture,accounting for 48.64%. Benzodiazepine was the main drugs abused or dependenced by hospital patients,accounting for 73.57%（206 cases）. There were also 83 cases of polydrug abuse,accounting for 29.64%. Among the patients with drug abuse or dependence,45.71% had no special feelings,41.07% had symptoms or felt uncomfortable after withdrawal; 64.64% was for improving their sleep quality. Conclusion Most patients with abuse or dependence of narcotic drugs and psychotropic drugs are middle- or senior-aged and have polydrug abuse. Benzodiazepine are the main abused drugs. The common reason for narcotic and psychotropic drug abuse or dependence is to have a good sleep.

Objective To investigate the antimicrobial resistance of clinical isolates from a hospital in Chongqing during one year according to CHINET project.Methods Disc diffusion test (K-B method) was employed to study the antimicrobial resistance. WHONET5 was used for data analysis.Results In one year period from 2004 to 2005,690 non-duplicate isolates were collect- ed.Enterobacter isolates showed the lowest resistance rate to imipenem and meropenem.About 37.5% of E.coli and 31.4% of K.pneumoniae isolates produced ESBLs,respectively.All ESBLs-producing strains were susceptible to imipenem and mer- openem.About 37.2%,39.4% and 48.9% of P.aeruginosa isolates were resistant to imipenem,meropenem and ceftazidime, respectively.Pandrug-resistant (PDR) P.aeruginosa was isolated from our hospital.All strains of A.baumannii were sus- ceptible to imipenem and meropenem.About 37.7% of A.baumannii were resistant to cefoperazone-sulbactam.Twenty-nine strains showed the same resistant pattern among non-susceptible strains of A.baumannii,mainly derived from 2 clones by PFGE analysis.Conclusions The surveillance results suggest that prevalent strain resistant to cefoperazone-sulbactam may pres- ent in some ICUs.Resistance rate to cefoperazone-sulbactam increased significantly.

Objective:To investigate the expression of wild type estrogen receptor(wER)and the ex-on-5 deleted ER(variant ER,vER)in human hepatocellular carcinoma(HCC)samples,and thereafteranalyze the possibility of HCC treatment by endocrine therapy.Methods:The mRNA expressions of wERand vER were analysed from 28 cases of HCC by RT-PCR.The expression of ER at the protein level wasdetected by immunohistochemistry(IHC).Results:IHC results showed that 39.3% of the HCC speci-mens expressed ER.The mRNA of wER was detected in 89.3%(25/28)of the HCC specimens whilethat of vER was detected in 96.4%(27/28).Twenty four out of 28 HCC cases(85.7%)expressedboth wER and vER.One out of 28 patients(3.5%)expressed only wER whereas 3 patients out of 28(10.7%)expressed vER only.Conclusion:Ninety six percent(27/28)of the HCC patients expressedvER,which suggests that the expression of vER is an important event in the development of HCC.

Objective:To investigate the electrocardiographic characteristics of left and right ventricles origin of premature ventricular contractions(PVCs) during V3 transition of precordial leads, right ventricular outflow tract (RVOT) anterior septum and right coronary sinus (RCC), and RVOT middle-posterior septum and left coronary sinus (LCC).Methods:From January 2017 to September 2019, 91 patients with ventricular extrasystole of outflow tract who had V3 transition in precordial lead and had successful radiofrequency ablation in RVOT anterior septum, middle posterior septum, LCC and RCC were selected for retrospective case control study.The electrocardiography measurements of PVCs were compared between the anteroseptal RVOT group and RCC group, as well as the middle-posterior septal RVOT group and the LCC group, respectively.The measurements included the R-wave amplitude in lead Ⅰ, Ⅱ, Ⅲ and aVF, R amplitude ratio in leads Ⅲ to Ⅱ, Q-wave amplitude in lead aVL and aVR, Q amplitude ratio in leads aVL to aVR, R-wave and S-wave amplitude from leads V1 to V3, the V2S/V3R index, the transition zone index, and the V2 transition ratio.Results:Thirty-six cases originated from the anteroseptal RVOT, and 11 from the LCC.Lead I R-wave amplitude in anterior septal RVOT was higher than LCC group((0.22±0.25) mV vs.(-0.17±0.33) mV; P=0.003). R-wave amplitude in lead Ⅱ was lower than that in the LCC group((1.59±0.35) mV vs.(1.76±0.27) mV; P=0.035). R-wave amplitude in lead aVF was lower compared with the LCC group((1.53±0.35) mV vs.(1.78±0.39) mV; P=0.050). The V2S/V3R index showed a significant difference between these two groups(1.99±0.66 vs.0.76±0.38; P<0.001). The V2 transition ratio also appeared a significant difference between the two groups(0.69±0.43 vs.1.05±0.35; P=0.005). PVCs arose from the middle-posterior septal RVOT in 32 cases, and from the RCC in 12 cases.Compared with RCC group, lead Ⅰ R-wave amplitude showed lower ((0.25±0.31) mV vs.(0.57±0.12) mV; P<0.001); R amplitude ratio in leads Ⅲ to Ⅱ higher (0.89±0.14 vs.0.72±0.18; P=0.002); Q amplitude in lead aVL((0.72±0.24) mV vs.(0.51±0.16) mV; P=0.002)higher, and Q amplitude ratio in leads aVL to aVR higher in the middle-posterior septal RVOT(0.76±0.23 vs.0.50±0.21; P=0.002). Conclusion:Among the cases with lead V3 transition, PVCs originated from the anteroseptal RVOT show significantly different R wave in lead Ⅰ, Ⅱ, aVF, V2S/V3R index, and the V2 transition ratio compared with those from the LCC.The PVCs from the middle-posterior septal RVOT and the RCC have different R wave in lead Ⅰ, R amplitude ratio in leads Ⅱ and Ⅲ, Q amplitude ratio in leads aVL and aVR.Combined with its different characteristics, it can help to identify the origin of left and right ventricles.
