Objective To evaluate the anti-tumour effect of 60℃ LipiodoI in the embolization of VX_2 hepatocarcinoma in rabbits.Methods VX_2 carcinoma cells were surgically implanted into the left liver lobe in 30 male New Zealand white rabbits,which were randomly divided into 3 groups by figure and table method with 10 rabbits in each group.Physiological saline,Lipiodol(37℃),and Lipiodol(60℃)were injected in each group via hepatic artery and liver cancer was embolized.The volume of tumour and serum level of aspartate aminotransferase(AST)were observed after one week,and the survival period of VX_2 rabbits was also observed.Results In the group of Lipiodol(60℃),the growth rate of tumour(0.92? 0.21)was significantly lower than that of control group(3.48?1.17)and Lipiodol(37℃)groups (1.69?0.26),respectively(F=34.95,P0.05),but was significantly higher than the control group(68.6?6.6)U/L(t=19.24,P

AIM To study the protective effects of Jingqi Capsules (Cordycps Militaris,Rehmanniae Radix Praeparata,Lycii Fructus,) on the damage to rat reproductive system induced by cyclophosphamide.METHODS After low and high dose groups of Jingqi Capsules and positive group were administered for two weeks in advance,cyclophosphamide [25 mg/(kg · d)] modeling was conducted consecutively by intraperitoneal injection for five days except the normal group,while the treatment groups were administered consecutively.All the rats were executed the day after the end of the modeling.Serum testosterone content was measured by radioimmunoassay;body weight,testis,epididymis and prostate of rats were weighed and organ coefficient was calculated;morphology of testis was observed by HE;sperm count and sperm motility were detected by CASA;apoptosis of cells was observed by TUNEL.RESULTS Compared with the model group,each dose group of Jingqi Capsules increased in the level of serum testosterone and organ coefficient of testis,epididymis and prostate.The damage to seminiferous epithelium relieved and the number of all spermatogenic cells increased.Sperm count and sperm motility increased.Decrease in apoptosis of cells was demonstrated by TUNEL.CONCLUSION Jingqi Capsules has protective effects on damage to rat reproductive system induced by cyclophosphamide.

BACKGROUND: Stellate ganglion block (SGB) is known to increase blood flow to the innervations area of the stellate ganglion. Near infrared spectroscopy reflects an increased blood volume and allows continuous, non-invasive, and bedside monitoring of regional cerebral oxygen saturation (rSO2). We investigated the influence of SGB on bilateral cerebral oxygenation using a near infrared spectroscopy. METHODS: SGB was performed on 30 patients with 1% lidocaine 10 ml using a paratracheal technique at the C6 level and confirmed by the presence of Horner's syndrome. The blood pressure (BP), heart rate (HR) and rSO2 were measured before SGB and 5, 10, 15 and 20 minutes after SGB. Tympanic temperature of each ear was measured prior to SGB and 20 minutes after SGB. RESULTS: The increments of the rSO2 on the block side from the baseline were statistically significant at 5, 10, 15 and 20 minutes. The rSO2 on the non-block side compared with the baseline, however, decreased at 15 and 20 minutes. The difference between the block and the non-block sides was significant at 15 and 20 minutes. The BP at 10, 15 and 20 minutes was increased and the HR was increased at 10 and 15 minutes. CONCLUSIONS: We observed an increment of the rSO2 on the block side from the baseline; however, the rSO2 on the non-block side decreased.

OBJECTIVETo analyze the electrical activity property changes in nucleus accumbens (NAc) of heroin-induced conditioned place preference (CPP) rats during different stages of heroin dependence and to explore NAc's roles in the formation of drug dependence.

METHODSRecording electrodes were bilaterally embedded into the NAcs of rats with the aid of stereotaxic apparatus, followed by establishment of heroin-dependent rat model. The NAc electrical activity during 3 different stages of heroin dependence, including heroin pre-exposure, immediate post-exposure and heroin withdrawal, were respectively recorded using EEG wireless telemetry techniques. The frequency distribution (ranging from 0.5 to 30 Hz) and the amplitude of NAc electrical activity were analyzed and measured.

RESULTSHeroin-dependent rat models were successfully established and their withdrawal symptoms were evident. All rats showed a conditioned place preference (CPP) for the white box after 5-10 days of heroin-exposure, and displayed a maximum withdrawal symptoms on 2d after heroin- withdrawal. During all statges of heroin-dependence, the NAc electrical activity contained the highest proportion of delta rhythm and the lowest proportion of alpha2 rhythm. The discharge frequence band was similar across different stages. There was a significantly increased ratio of low-frequency discharges (delta rhythm) and decreased ratio of high-frequency discharges (beta rhythm) in NAc of rats during the immediate post- heroin exposure stage when compared with that during pre-exposure and heroin withdrawal stages. During the withdrawal stage, the ratio of at rhythm was significantly lower than during pre- and post-heroin exposure stages (P < 0.01). Further, the mean discharge amplitude in NAcs during immediate post-exposure and withdrawal stages was significantly increased relative to pre-exposure stage. However, the mean discharge amplitude during heroin withdrawal stage was significantly lower than during immediate post-exposure stage.

CONCLUSIONThe electrical activity properties in rat NAcs showed a significant change during different stages of heroin-dependence, which suggested that neuronal activities in NAcs might contribute to the modulation of drug-dependence.

OBJECTIVE To investigate the prevalence of the antimicrobial and disinfectant-resistant genes from the clinical isolates of meticillin-resistant Staphylococcus aureus(MRSA) and meticillin-resistant Staphylococcus haemolyticus(MRSH).METHODS The identification and antimicrobial susceptibility test of MRSA and MRSH isolates were determined by MicroScan auto SCAN4.PCR was used for detecting antimicrobial and disinfectant-resistant genes.The minimal inhibitory concentration(MIC)and minimal bactericidal concentration(MBC)of benzalkonium bromide to staphylococci that carried qacA/B gene were determined by broth dilution method.RESULTS The positive rates of qacA/B,aac(6′)/aph(2″),aph(3′)-Ⅲ,ant(4′,4″),TEM,erm,and tetM from 24 MRSH strains were 37.5%,87.5%,33.3%,29.2%,95.8%,and 94.4%;and 91.7%.respectively,and 30.6%,91.7%,72.2%,8.3%,100%,94.4% and 91.7%,respectively.The MIC of benzalkonium bromide for MRSH and MRSA were both 32-128 mg/L,MBC for MRSH was 256-512 mg/L and for MRSA was 512-1024 mg/L.The MIC and MBC of benzalkonium bromide for standard strain ATCC25923 were 16 mg/L and 32mg/L,respectively.CONCLUSIONS Antimicrobial and disinfectant-resistant genes are commonly prevalent in MRSA and MRSH isolates.

OBJECTIVES: This study was conducted to identify differences in job stress, satisfaction and commitment of cooking employees working in hotel kitchens with and without HACCP systems. METHODS: Culinary employees of 12 five-star hotels were surveyed and 504 valid data were used for SPSS analysis. Sub factors of working environment factors (job stress, job satisfaction, and job commitment) were examined for analysis. RESULTS: The results showed that hotels that implemented the HACCP system had significantly higher values for the five sub factors of employee job stress (job demand, relationship conflict, organizational system, lack of job autonomy, and job instability; p < 0.001). For the sub factors of job satisfaction (internal and external satisfaction) statistic showed a statistically significant value in hotels that did not implement the HACCP system (p < 0.001). Job attachment and job importance, which are sub factors of job commitment, showed no difference in relation to the implementation of HACCP system, and job responsibility showed a higher p-value in hotels that did not implement HACCP (p < 0.05). CONCLUSIONS: The results of the study indicate that culinary employees working at venues with HACCP systems have more job related stress, lower job satisfaction and partially less job commitment. Based on this outcome, venues that have already implemented or are planning to implement HACCP systems should consider the implications regarding their management of employees. Managerial policies that enhance autonomy, job stability, achievement, self-development, promotion, and compensation should also be implemented. Finally, meticulous attention and high investments into the work environment and human resources are necessary.

OBJECTIVETo compare the intervention effects of four traditional Chinese medicines (TCMs) with typical cold or hot property on body temperature and temperature-sensitive transient receptor potential ion channel proteins (TRPs) of rats with yeast-induced fever.

METHODThe pyrexia model was induced by injecting yeast suspension subcutaneously. Totally 108 male SD rats were randomly divided into the normal group, the model group, the Rhei Radix et Rhizoma treated group, the Coptidis Rhizoma treated group, the Euodiae Fructus treated group, and the Alpiniae Officinarum Rhizoma treated group, with 18 rats in each group. At the 4 h, 8 h and 12 h after injection of yeast, the rats were sacrificed to collect their hypothalamus and dorsal root ganglion. The expressions of TRPV1 and TRPM8 were detected by immunohistochemistry and Western blot method.

RESULTCompared with the normal group, after injection of yeast, the temperature of rats in the model group notably increased, and reached the peak at 8 h (P < 0.01). The TRPV1 level in hypothalamus and dorsal root ganglia (DRG) of the model group significantly increased, whereas the TRPM8 level significantly reduced. Compared with the model group, the Rhei Radix et Rhizoma group and the Coptidis Rhizoma group showed significant decrease in the high body temperature of rats caused by yeast, down-regulation in the expression of TRPV1, and up-regulation in the expression of TRPM8 (P < 0.05 or P < 0.01). Euodiae Fructus and Alpiniae Officinarum Rhizoma had no significant effect on either temperature or TRPs of fever rats.

CONCLUSIONRhei Radix et Rhizoma and Coptidis Rhizoma, both are TCMs with cold property, can reduce the temperature of fever rats induced by yeast, which may be related to their effective regulation of TRPV1 and TRPM8 in hypothalamus and DRG, while Euodiae Fructus and Alpiniae Officinarum Rhizoma had no relevant effect.
