Objective: To observe the effect of electroacupuncture plus drug anesthesia on pain and stress response in patients after radical surgery for stomach cancer.Methods: A total of 60 patients were randomized into a control group and an observation group by the random number table, with 30 cases in each group. The control group was given conventional drug anesthesia. The observation group was given additional electroacupuncture intervention. Before anesthesia and 2 h, 12 h and 24 h after surgery, the visual analog scale (VAS) was scored, the heart rate, the mean arterial pressure, and the levels of serum β-endorphin (β-EP) and adrenocorticotrophic hormone (ACTH) were measured. Results: Two hours, 12 h and 24 h after surgery, the VAS scores of both groups were higher than those before anesthesia (all P<0.05), and the VAS scores in the observation group were lower than those in the control group at the same time points (all P<0.05). Two hours, 12 h and 24 h after surgery, the heart rates and mean arterial pressures in the control group were significantly higher than those before anesthesia (all P<0.05), while there were no significant intra-group differences in the observation group (all P>0.05), and the indicators were lower than those in the control group at the same time points (all P<0.05). Two hours, 12 h and 24 h after surgery, the serum β-EP levels in the observation group were significantly higher than those before anesthesia (all P<0.05), and significantly higher than those in the control group at the same time points (all P<0.05). Two hours, 12 h and 24 h after surgery, the serum ACTH levels in the control group were significantly higher than those before anesthesia (all P<0.05), and were significantly higher than those in the observation group at the same time points (all P<0.05). Conclusion: Electroacupuncture plus drug anesthesia can significantly relieve pain and stress response in patients after radical surgery for stomach cancer.

Objective To perform a biomechanical study on and compare the stability of internal fixation with closed Kirschner wire in different spots from the epicondylus medialis to sulcus nervi ulnaris and epicondylus lateralis of humerus in the treatment of GartlandⅢsupracondylar fractures of humerus in children in order to provide basis for avoiding cubitus varus in clinic.Methods Twenty models of su- pracondylar fractures were made from ten humerus samples,then divided into two groups(group A and group B).They were fixed with closed Kirschner'wires.Ulnar Kirschner wire varied.In group A five spots were selected averagely from the epicondylus medialis to the sulcus nervi ulnaris.Kirschner wires entered from one of the five spots into another spot of humerus.In group B Kirschner wires entered defferent spots of humerus from the central spot of sulcus nervi ulnaris.Biomechanical tests were carried out,such as axial load,axial displacement,stress intensity,axial rigidity and anti-twisty ability.Forty-six children with Gart- landⅢsupracondylar fracture of humerus were treated and followed up for more than one year.Results In beth groups,with the angle of Kirschner wires and fracture side increasing,the strain and the vertical displacement decreased,the stress intensity and the axial rigidity increased,and the anti-twists ability was enhanced.There was statistic difference(P＜0.05).The follow-up of the 46 patients showed the elbow joint function recovered well with no cubitus varus malformation.Conclusion Internal fixation with closed Kirschner wires in sulcus nervi ulnaris from the epicondylus medialis and the epicondylns lateralis of humerus for GartlandⅢsupracondylar fracture of humerus in children has the advantages of enhancing bio- mechanical stability,effective prevention of secondary replacement of outlying black of the fracture and a- voidance of cubitus varus.It can be widely used clinically.

A RP-HPLC method was established for simultaneous determination of phellodendrine hydrochloride (PH1), magnoflorine hydrochloride (MH), jatrorrhizine hydrochloride (JH), palmatine hydrochloride (PH2) and berberine hydrochloride (BH) in Phellodendri Chinensis Cortex by using ionic liquids as mobile phase additives. The separation was performed on a Kromasil C18 (4.6 mm x 250 mm, 5 μm) coupled with ultraviolet (UV) detection. The effect of extraction solvent, detection wavelength, length of alkyl chain on different imidazolium ionic liquids and concentration of ionic liquids on the separation and determination of alkaloids were investigated. Ionic liquid, [BMIm] BF4, can obviously improve the resolution and peak shape. This ILs-HPLC method is simple, rapid, and reliable, which can be used for determination of alkaloids in Phellodenddri Chinensis Cortex.

OBJECTIVETo investigate the changes in characteristics of periodontal pathogens in subgingival plaque of patients with puberty gingivitis and its relevance with clinical symptoms.

METHODSA total of 108 subgingival plaque samples were collected from 30 patients with puberty gingivitis (Group G), 9 cases of chronic periodontitis (Group P) and 15 healthy controls (Group H). The age of the 54 participants was from 11 to 17. The black-pigmented bacteria (BPB), Fusobacterium nucleatum (Fn), Actinobacillus actinomycetemcomitans (Aa), Actinomyces were detected using bacterial culture. The probing depth (PD), gingival index (GI), bleeding index (BI) and attachment loss (AL) were also recorded.

RESULTSIn all these three groups, the detection rates of black-pigmented bacteria were: 3%, 30% and 100%; Fn were: 30%, 68% and 94%, statistically significantly different (P < 0.01). The lgCFU/ml of black-pigmented bacteria and Actinomyces was higher in mild-moderate group [(3.8 +/- 0.7) and (5.3 +/- 0.9)] than in Group H (P < 0.001). The lgCFU/ml of black-pigmented bacteria and Fn significantly was higher in severe inflammation group [(4.7 +/- 1.2) and (4.4 +/- 0.8)] than in the mild-moderate group (P < 0.01). The lgCFU/ml of black-pigmented bacteria, Fn and Aa was higher in severe gingivitis group [(6.6 +/- 1.0), (5.5 +/- 1.0) and (4.2 +/- 1.7)] than in mild gingivitis group (P < 0.01). The detection rate and lgCFU/ml of black-pigmented bacteria, Fn and Aa were both positively correlated with BI, PD and AL.

CONCLUSIONSIn the stage of severe gingivitis, the periodontal pathogens increased markedly, suggesting that risk of further destruction of periodontal tissue may exist.

Objective To isolate and identify the adult neural stem cells from the parenchyma of spinal cord in adult mouse.Methods The parenchymal spinal cord from adult mouse was dissected and dissociated by mechanical trituration.The tissue suspension was cultured in serum-free DMEM/F12 medium supplemented with EGF and B27.The cell colonies generated from a single cell were screened by limited dilution and incubated with BrdU.The cell colonies were transferred into medium with serum to induce differentiation.The cells were identified with antibodies to Nestin,BrdU,MAP2 and GFAP by immunofluorescence staining.Results The cells were cultured for seven days to generate proliferative neurospheres.The majority of cells in these neurospheres expressed Nestin and were differentiated into MAP2-positive cells and GFAP-positive cells in medium containing with fetal bovine serum.Conclusion A significant number of neural stem cells are present in the parenchymal adult mouse spinal cord and can proliferate and also give rise to neurons and glia in vitro.

Objective To investigate the association of angiotensinogen(AGT)gene A-6G、T174M and G-217A polymorphisms with the risk of essential hypertension(EH)in the elderly of Han nationality.Methods Genotypes of AGT gene A-6G,T174M and G-217A polymorphisms in 177 aged EH patients and 86 sex and age-matched controls were analyzed with gene chip technology.Results The A-6G and T174M polymorphisms of AGT gene were significantly associated with EH.The numbers of the three genotypes of A-6G were 113,58 and 6 in the patient group and 70,15 and 1 in the control group(P= 0.014)and those of T174M were 94,77 and 6,60,25 and 1(P=0.031),respectively.G-217A polymorphism was not related to EH.Individuals carrying A-6G AA and T174M CC genotypes showed 57% and 56% lower risk of EH(OR=0.43;95%CI=0.23-0.82 and OR=0.44;95%CI=0.25-0.79, respectively).Conclusions The A-6G AA and the T174M CC genotype may be related with decreased risk of EH and G-217A polymorphism may have little role in the etiology of EH in Han nationality.
