Objective To investigate the effects of nursing intervention on the rehabilitation of patients with benign paroxysmal positional vertigo (BPPV).Methods 64 BPPV patients were randomly divided into control group and observation group, with 32 cases in each group.The control group received otorhinolaryngology routine nursing, while the observation group was managed with continuously systemic nursing interventions, including manipulative re-duction, psychological nursing intervention, health education, head nursing, follow -up and family nursing interven-tion.The Hamilton Anxiety Scale (HAMA) and Hamilton Depression Rating Scale (HDRS) were applied to evaluate the intervention effects.Results Cure rate of the observation group was significantly higher than that of the control group, and recurrence rate of the observation group was obviously lower than that of the control group(p <0.05).The anxiety and depression assessment of the observation group was significantly lower than that of the control group, with statistical difference (p <0.05).Conclusion Systemic nursing intervention can effectively improve the rehabilita-tion of patients with BPPV, and reduce recurrence rate.

The effects of nicorandil ( NICO ) on the contractility, automati -city, excitability, functional refractory period ( FRP ) & dose-response curves for isoprenaline as well as calcium were studied in guinea pig papillary muscles. NICO could decrease the amplitude of contraction of papillary muscles dose-dependently. Propranolol and NICO might antagonize the inotropic effect of isoprenallne. Verapamil & NICO induced Ca2+ antagonistic effects in a non-competitive manner, & the maximal Ca2+ response of papillary muscles decreased signifi- cantly. The automaticity of papillary muscles was decreased Significantly when the concentration of NICO reached 1.4 mmol/L, but exerted no effect on their excitability & the functional refractory period.

Objective To investigate the distribution of carbapenemase-resistant genes carried by multi-drug resistant Acineto-bacter baumannii .Methods 80 strains of multi-drug resistant Acinetobacter baumannii were collected .Polymerase chain reaction (PCR)wasusedtodetectcarbapenemase-resistantgenes,suchasOXA-23,OXA-24,OXA-51,OXA-58,SIM,IMP,VIM ,GIMand SPM ,in multi-drug resistant Acinetobacter baumannii .Results Drug resistant gene OXA-23 [49 (61 .3% )] ,OXA-51 [73 (91 .3% )] ,OXA-58[7(8 .8% )] ,OXA-24[1(1 .3% )] ,IMP[17(21 .3% )] and VIM[2(2 .5% )] were found in 80 strains of multi-drug resistant Acinetobacter baumannii ,while GIM ,SIM and SPM gene were not found .Conclusion IMP ,OXA ,VIM is the main genotypes carried by multi-drug resistant Acinetobacter baumannii .

Objective To discuss the effect of group social skills training on improving psychiatric symptoms and disability and the family relationship in patients with schizophrenia.Methods 101 followup patients of rehabilitation with schizophrenia in mental health center of a top three hospital and in a community were chosen from June 2011 to August 2012.Based on the principle of voluntary,45 and 56 patients were grouped into the control group and the intervention group,respectively.The scores of psychiatric symptoms,mental disability and family relationship were compared between two groups by independent sample test.Results At the end of six months,the score of positive and negative symptoms and mental disability were lower in the intervention group,and there was significant difference in different measuring time,the interaction existed between the intervention and the measuring time.Meanwhile,the total score of family concern in the intervention group was higher than that in the control group,and there was significant difference in different measuring time,no interaction existed between the intervention and the measuring time.Conclusions Group training of social skills could improve psychiatric symptoms and the family relationship of patients with schizophrenia,reduce mental disability and promote recovery of patients.

Objective: To observe the effects of electroacupuncture (EA) pretreatment on M1 polarization of alveolar macrophages (AMs) in rats with acute lung injury (ALI) induced by lipopolysaccharide (LPS), and to explore the potential protective mechanism of EA.Methods: Forty Sprague-Dawley rats were randomly divided into a normal group, a model group, and three groups of EA pretreatment [including a Chize (LU5) group, a Zusanli (ST36) group and a Chize (LU5) plus Zusanli (ST36) group], with eight rats in each group. The model rats of ALI were established by instilling LPS [2 mg/(kg·bw)] into the trachea of rats for 3 h. The rats in each EA pretreatment group were pretreated with EA for 30 min per day at the corresponding bilateral acupoints 6 d before instilling LPS. Three hours after modeling, the pulmonary function of the rats was tested, and the lung tissue was taken to calculate the ratio of lung wet weight to dry weight (W/D). The pathological lung changes and the injury score were observed by hematoxylin-eosin staining. The contents of tumor necrosis factor (TNF)-α, interleukin (IL)-1β, and myeloperoxidase (MPO) in rat's bronchoalveolar lavage fluid (BALF) were detected by enzyme-linked immunosorbent assay. The mRNA and protein expression levels of M1 macrophage markers clusters of differentiation 86 (CD86), inducible nitric oxide synthase (iNOS), and its signaling pathway factor Toll-like receptor (TLR) 4, and nuclear factor-κB (NF-κB) p65 in the alveoli were detected by fluorescence quantitative polymerase chain reaction and Western blot, respectively. Results: After being induced by LPS, the pulmonary function of the model rats showed that the forced expiratory volume in 0.1 s (FEV0.1), forced expiratory volume in 0.3 s (FEV0.3), and their respective ratios of FEV to forced vital capacity (FVC) (including FEV0.1/FVC and FEV0.3/FVC) were significantly decreased (P<0.01), while the W/D of lung tissue was increased (P<0.01). The score of lung injury was significantly higher (P<0.01). The contents of TNF-α, IL-1β, and MPO in the BALF and the mRNA and protein expression levels of CD86, iNOS, TLR4, and NF-κB p65 in the lung tissue were significantly increased (P<0.01). After EA pretreatment, the FEV0.1, FEV0.3, FEV0.1/FVC, and FEV0.3/FVC were significantly increased, the lung injury score decreased significantly, and the contents of TNF-α, IL-1β, and MPO in the BALF and the expression levels of CD86, iNOS, TLR4, and NF-κB p65 mRNAs and proteins in the alveoli decreased significantly (P<0.05 or P<0.01). Compared with the other two single acupoint groups, the contents of TNF-α, IL-1β, and MPO in the BALF and the expression levels of CD86, iNOS, TLR4, and NF-κB p65 mRNAs in the alveoli in the Chize (LU5) plus Zusanli (ST36) group were significantly lower (P<0.01). Conclusion: EA pretreatment at Chize (LU5) and Zusanli (ST36) can inhibit inflammation and reduce pulmonary injury in ALI rats induced by LPS. The effect of the combination of Chize (LU5) and Zusanli (ST36) is better than that of using these two acupoints separately, and its mechanism may be related to the inhibition of AMs' M1 polarization by down-regulation TLR4/NF-κB signaling pathway.

OBJECTIVETo study the effect of epidermal growth factor(EGF) and different concentrations of gonadotrophin (Gn) on the in vitro maturation of human oocytes.

METHODSEGF was added to the vitro culture medium in order to observe the effect of Gn combined with or without EGF on the result of in vitro maturation. The concentrations of hCG and FSH were changed respectively to observe the difference between the results.

RESULTSAdding EGF to the culture medium improved the maturation rate of oocyte significantly (P < 0.05). There was no difference between the results with different concentrations of hCG and FSH in the culture medium.

CONCLUSIONEGF can improve the results of the in vitro maturation of human oocytes by increasing the maturation rate significantly. Increasing the concentration of Gn does not influence the results of in vitro maturation.
