Objective To investigate the role of proliferating cell nuclear antigen (PCNA) and cyclin dependent kinase 2 (CDK2) in inhibition of vascular smooth muscle cells (VSMCs) proliferation by gax gene. Methods After being transfected by AdCMV-gax, the expression of gax, PCNA and CDK2 in VSMCs were assessed. The effect of gax overexpressions on VSMCs proliferation was observed by 3 H-thymidine incorporation. Results After AdCMV-gax was transfected to VSMCs, the level of Gax protein expression was significantly higher than that before transfection. PCNA and CDK2 expressions were decreased after VSMCs were transfacted with AdCMV-gax. The level of 3 H-thymidine incorporation was decreased significantly in with AdCMV-gax transfected VSMCs compared with that in non-transfected VSMCs. Conclusion The mechanism of inhibition of VSMCs proliferation by gax gene is related with depression of expression of PCNA and CDK2.

HPLC-ESI-MS technology was applied to determine the hydrolyzed peptides of red cubilose and white Abscubilose for the comparison of similarities and differences between different kinds of cubiloses' hydrolysis polypeptide primary structure.SDS-PAGE,capillary high-performance liquid chromatography and ESI-MS were used to detect the purity and peptide mapping of samples.Mascot 2.2 sof tware was used to search the database.The basepeak figure in mass spectrometry analysis showed good consistency of hydrolyzed peptides between red cubilose and white cubilose.The Mascot 2.2 sof tware was used to search the poultry database which had been downloaded from the UniProt.A total of 73 kinds of proteins from white cubilose were identified.And a total of 51 kinds of proteins from red cubilose were identified.There were 30 kinds of same proteins from both cubilose.It was concluded that the hydrolyzed peptides had relatively high similarity between red cubilose and white cubilose.The same proteins from both red and white cubilose can be used as the quality control characteristics of cubilose products.

OBJECTIVETo explore the differential proteomic expression in human liver cells L-02 after exposure to HQ.

METHODSSubcultured L-02 cells were treated by HQ for 24 h at a 1 x 10(-4) mol/L concentration and a blank group was set as the control. Immediately after the treatment, total cellular proteins were extracted and separated by 2-DE, and the images were analyzed by PDQuest software. The experiment was totally repeated 3 times with 3 repetitions for each group every time. The well repeated spots were identified by MALDI-TOF MS and then searched in NCBI human protein database with Mascot.

RESULTSAbout 1,000 spots per gel were found. Compared with the control group, 17, 18 and 24 spots were significantly altered in 3 separate experiments. The 4 well repeated spots were identified by MALDI-TOF MS as Rho GDP dissociation inhibitor GDI alpha, 6-phosphogluconolactonase, erbB3 binding protein EBP1 and lamin A/C, isoform 1 precursor. They were involved in cell skeleton, signal transduction and energy metabolization in functional classification.

CONCLUSIONHydroquinone can change the protein expression in liver cells, which provides clues for exploring the toxic mechanism.

OBJECTIVETo search for an effective therapy for prolapse of lumbar intervertebral disc of yang deficiency and cold coagulation type.

METHODSOne hundred and twenty-six cases were randomly divided into a combined electroacupuncture and Chinese herb group (n=49), an electroacupuncture group (n=42) and a Chinese herb group (n=35). The combined electroacupuncture and Chinese herb group was treated with electroacupuncture at Dachangshu (BL 25), Guanyuanshu (BL 26), Xiaochangshu (BL 27) and Yaoyangguan (GV 3) and oral administration of Chinese herbs for cold-removing and yang-invigorating. The electroacupuncture group was treated with the same electroacupuncture treatment alone and the Chinese herb group with the same self Chinese herbs alone. The therapeutic effects were observed after treatment for 20 days, and the recurrence rates were followed up at 180 days after the last treatment among the three groups.

RESULTSThe cured-markedly effective rate was 79.6% in the combined electroacupuncture and Chinese herb group, 54.8% in the electroacupuncture group and 51.4% in the Chinese herb group, the combined electroacupuncture and Chinese herb group being significantly better than both the electroacupuncture group and the Chinese herb group (both P<0.05) and the therapeutic effect of both the electroacupuncture group and the Chinese herb group being similar (P>0.05). The recurrence rate after 180 days was 15.4% in the combined electroacupuncture and Chinese herb group, 83.3% in the electroacupuncture group and 80.0% in the Chinese herb group, with more obvious decrease in the combined electroacupuncture and Chinese herb group (both P<0.01).

CONCLUSIONElectroacupuncture combined with Chinese herbs is a better therapy for prolapse of lumbar intervertebral disc of yang deficiency and cold coagulation type.

OBJECTIVETo assess the efficacy of quick meridian needling therapy plus scalp acupuncture on infantile cerebral palsy (CP).

METHODSOne hundred and forty-seven cases of CP were randomly divided into a quick meridian needling therapy plus scalp acupuncture group (group A), a conventional acupuncture group (group B) and a scalp acupuncture group (group C), 49 cases in each one. In group A, quick needling was applied to the Conception Vessel, Governor Vessel, Hand-Yangming, Hand-Jueyin, Foot-Yangming and Foot-Taiyin meridians distributed on four limbs and trunk. One pricking point was 10 mm far from the other one. In scalp acupuncture, motor area, equilibrium area, sensory area, tremor-control area, foot-motor-sensory area, speech No. 2 area, speech No. 3 area, Baihui (GV 20), Sishencong (EX-HN 1), etc. were selected. The needles were stimulated with rotating manipulation and remained for 30-60 min. In group B, the conventional acupuncture was adopted mainly at Dazhui (GV 14), Shenzhu (GV 12), Fengfu (GV 16) and others. In group C, the scalp acupuncture was used and the points selected were same as those in group A for scalp acupuncture treatment. The scores of Gross Motor Function Measure (GMFM) were observed before and after treatment for children. The clinical efficacy of each group was evaluated. By follow-up for 12 months, the condition of independent walking was observed.

RESULTSThe total effective rate in group A was 79.6% (39/49), which was superior to that of group B [49.0% (24/49)] and group C [51.0% (25/ 49)] respectively (both P < 0.05). After treatment, GMFM scores of children were all improved significantly in 3 groups (P < 0.001, P < 0.05), of which, the improvement extent in group A was superior to that of other two groups (both P < 0.05). It was found after follow-up for 1 year that 31 cases could walk independently in group A, which was more than group B (17 cases) and group C (16 cases).

CONCLUSIONThe quick meridian needling therapy plus scalp acupuncture can improve significantly limb motor function of children with cerebral palsy and its therapeutic effect is superior to conventional acupuncture and simple scalp acupuncture.

OBJECTIVETo investigate the changes of gene expression in rat neurons induced by 1.8 GHz radiofrequency electromagnetic fields (RF EMF) and to screen for the RF EMF-responsive genes.

METHODSNewly-born SD rats in 24 hours were sacrificed to obtain cortex and hippocampus neurons. The cells were divided randomly into two groups: the experiment group (the irradiation group) and the control group (the false irradiation group). In the irradiation group, after twelve days' culture, neurons were exposed to 1.8 GHz RF EMF modulated by 217 Hz at a specific absorption rate (SAR) of 2 W/kg for 24 hours (5 minutes on/10 minutes off) while in the false control group, the neurons were put in the same waveguide as in the irradiation group, but were not exposed to any irradiation. The total RNA was isolated and purified immediately after exposure. The affymetrix rat neurobiology U34 assay was used for detecting the changes in gene expression profile according to the manufacturer's instruction. RF EMF-responsive candidate gene was confirmed by using ribonuclease protection assay (RPA).

RESULTSAmong 1200 candidate genes, the expression levels of 34 genes were up or down regulated. Microtubule associated protein 2 (Map2) gene was selected as the candidate and subjected to further analysis. RPA data clearly revealed that Map2 was statistically significantly up-regulated after neurons were exposed to the RF EMF (P < 0.05).

CONCLUSIONThe modulation of gene expression and function of Map2 as a neuron specific cytoskeleton protein is crucial to maintain the normal framework and function of neurons. The finding that 1.8 GHz RF EMF exposure increases the expression of Map2 might indicate some unknown effects of RF EMF on neurons.

Objective:To explore the relationship between occupational stress and metabolic syndrome (MS) in operating room nurses.Methods:In July 2019, 179 nurses in the operating room of a third-class A hospital in Shandong Province were selected as the research objects. The self-designed questionnaire was used to investigate the general situation, and "Nurse Job Stressor Scale" was used to investigate the occupational stress level of nursing staff. The height, weight, waist circumference, blood pressure, fasting blood glucose, total cholesterol, triglycerides, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, ischemia-modified albumin, lipoprotein associated phospholipase A2 were measured. The nursing staff were divided into MS group and non-MS group, and the occupational stress levels of the two groups were compared. Chi square test or Fisher test were used to compare the counting data between groups; the measurement data were expressed by Mean±SD, and the comparison between groups was performed with t test. Multiple logistic regression analysis was used to analyze the influencing factors of MS.Results:The overall occupational stress level of nurses in operating room was (450.58±141.77) points, which was significantly lower than the norm score ( P<0.05) ; Compared with non-MS group, the overall occupational stress level, work nature, workload and patient related factors in MS group were significantly higher, and the differences were statistically significant ( P<0.05) ; The prevalence of abdominal obesity, hypertriglyceridemia, hyperglycemia and hypertension were significantly different among the groups with different occupational stress levels ( P<0.05) . After adjusting waist circumference, triglyceride, systolic blood pressure, high density lipoprotein, ischemia modified albumin and lipoprotein associated phospholipase A2, the total score of occupational stress was the risk factor of MS in operating room nurses ( P<0.05) . Conclusion:The occupational stress level of nurses in operating room is related to the prevalence of MS.
