Objective To compare the curative effects of different ideas for application of vasoactive drugs in patients of congenital heart disease with SPAH during perioperative period and to choose a method to improve the survival rate of patients with high-risk SPAH.Methods Thirty two patients were separated into two groups randomly,one group was treated by vasodilator to dilate the pulmonary artery and decrease the pulmonary pressure as conventional therapeutic strategy,the other was treated by vasoactive drugs to decrease the right cardiac output,which maintain the normal vessel resistance and cardiac output and reduce right heart failure.Indexes were recorded respectively,including hemodynamic,right cardiac working index(RCWI),the time of using respirator and postoperative complications to compare the differences.Results Indexes were recorded in two groups as following:Aortic/pulmonary artery pressure inversion(6.25％ vs.56.25％),RCWI (1626.87 ±411.23 vs.3808.99 ± 275.52),incidence of right heart failure (6.25％ vs.93.75％),respirator applying time[(68.00 ± 7.17) h vs.(115.00 ± 13.68) h],ICU time[(5.0 ± 0.8) d vs.(8.0 ± 1.5) d],incidence of postoperative pulmonary complications (6.25％ vs.81.25％),mortality(0 vs.12.5％).Conclusion The new therapeutic idea that using vasoactive drugs to reduce RCW1 and to maintain peripheral vessel resistance and appropriate cardiac output is superior for postoperative complications and mortality reduction.

Objective To explore the effect of bundle hand hygiene intervention in controlling healthcare-associated infec-tion(HAI)in a primary comprehensive hospital,so as to improve hand hygiene compliance and correct rate,and reduce AHI rate. Methods In January-June 2014,bundle hand hygiene intervention among health care workers (HCWs)in a hospital was performed,hand hygiene knowledge awareness rate,hand hygiene compliance and correct rate,hand sanitizer usage and HAI rate before and after intervention were compared. Results After performing intervention for six months,the awareness rate of hand hygiene knowledge(concept,significance,indications,methods,sanitizer use)of HCWs improved com-pared with before intervention (P<0.05);hand hygiene compliance and correct rate were significantly higher than before inter-vention (77.92% vs 49.78% ;76.47% vs 37.72% )(P<0.05). Hand sanitizer usage increased from 2.14mL/bed-day to 4.63 mL/bed-day ,HAI rate decreased from 1.97% to 1.54% (P<0.05).Conclusion Bundle hand hygiene intervention can improve HCWs’knowledge awareness,compliance and execution rate of hand hygiene,and effectively reduce HAI rate.

Objective To explore the effect of DR on the expression of inhibitory neurotransmitter ,γ-aminobutyric acid ( GABA) and brain derived neurotrophic factor ( BDNF) in the primary visual cortex of young cats .Methods Totally 6 cats were wsed in this study . Nissl staining was used for cortical layer identification and cell counting . Immunohistochemical techniques were utilized to label GABA-and BDNF-positive neurons .Sections were observed under an Olympus light microscope and photographed with a digital camera .The cell density and absorbance of immunoreactivity were measured with Image-Pro Express 6.0 softwares .Results Our results showed that the mean density of Nissl-stained neurons in the primary visual cortex ( V1) of the DR group showed no significant difference from that of the control group . However , the mean density of GABA-immunoreactive neurons in each cortical layer of V 1 in DR cats was significantly higher than that in control cats .The mean immunoreactive intensity of GABA-positive neurons , as indicated by the average absorbance , increased significantly in DR cats relative to control ones . Accompanied with the elevation of GABA expression, DR enhanced BDNF expression in V1, as indicated by an increased mean density of BDNF-positive neurons and BDNF-immunoreactive average absorbance in DR cats relative to controls .Conclusion These results indicate that dietary restriction leads to a concurrent expression upregulation of GABA and BDNF , which may likely compensate for brain functional degradation during senescence and thus delay aging process .

BACKGROUND:In oral warm and moisture circumstance, al oy which contains Be is easily to be eroded to release Be2+. But there is stil no research focusing on beryl ium influence on genotype of Porphyromonas gingivalis fimbriae gene cluster. OBJECTIVE:To investigate Be 2+effect on genotype of Porphyromonas gingivalis fimbriae gene cluster. METHODS:The revived Porphyromonas gingivalis was resuscitated for 48 hours in the anaerobic culture medium with different concentration of Be 2+(10×10-6, 5×10-6, 1.25×10-6). Through PCR amplification and sequencing, we investigated the effects of Be2+RESULTS AND CONCLUSION:(1) When Be on genotypes of Porphyromonas gingivalis fimbriae gene cluster. 2+concentration was 5×10-6, we found the peak of 217 and 257 sites on DNA sequence expressing G/A overlap peak, different from G single peak of the other groups, suggesting the suspicious bases changes, part of the single base G mutated into A. (2) On al concentrations, we found a base group composed of seven A bases was inserted into the 101 site of DNA sequence. Up to now, there is no direct contacts of the mutations occurring to Be2+concentration. Changes of gene may lead to the shifting of the reading frame, the abnormal synthesis of proteins, the change of Porphyromonas gingivalis fimA gene toxicity, and lastly the unbalance of the micro-ecological environment.

BACKGROUND: The study of tissue-engineered cartilage with predetermined shaping and regeneration has provided novel ideas and techniques for repair of laryngeal cartilage erosion; however, due to the special natures of the morphology, location and function of laryngeal cartilage, tissue engineering research has not, to date, exhibited its ful advantages in the reconstruction of laryngeal cartilage. OBJECTIVE:To explore the feasibility of building tissue-engineered larynx-shaped cartilage using poly(3-hydroxybutyrate-co-3-hydroxyhexanoate) (PHBHH) as a scaffold filed and encapsulated with pedicled myofascial flaps. METHODS:Porous PHBHH was prepared and formed into a holow like larynx-shape, and the cel PHBHH composites were cultured for 1 weekin vitro prior to implantationin vivo. The cel-PHBHH composite was filed and encapsulated with myofascial flaps with the pedicle forin situ implantation in nine rabbits as experimental group. PHBHH scaffold with no chondrocytes was implanted alone in three rabbits as control group. Cartilage regeneration was assessed at 6, 12 and 18 weeks after surgery through morphological observation, histological and immunohistochemical detection. RESULTS AND CONCLUSION: In the experimental group, the shape and porosity (> 90%) of the material were ideal, the cels exhibited good adhesion with the material and the blood supply within the myofascial flap with pedicle was rich for effective filing and encapsulation of the cel PHBHH composite. Tissue-engineered laryngeal cartilage with the holow, semi-trumpet shape was idealy formed at 6 weeks after the surgery. Further maturation of the cartilage was observed at 12 and 18 weeks after the surgery. However, there was no cartilage tissue in the control group. This study shows that PHBHH is a suitable material for the formation of a holow, semi-trumpet shape with good celular compatibility. Myofascial flap filing and encapsulating can be used to build tissue-engineered laryngeal cartilage with a holow, semi-trumpet shape.

Objective To investigate the effect of massaging Changqiang acupuncture point during the second labor course of primiparas. Methods 124 primiparas were randomized into the observation group(63 cases)and the control group (61 cases). In the observation group, after entering the second stage of labor, Changqiang point was massaged upwards by using index finger and middle finger, and at the same time primiparas were guided to hold breath to coordinate with uterine contraction to make effort to the anus point which was massaged. While the control group were directed with routine way of correctly using abdominal pressure during process of uterine contraction in the second stage of labor. Results The lasting time of uterine contraction was significantly longer in the observation group than in the control group, the time of second stage of labor was shorter, and the amount of postpartum hemorrhage in the observation group was less than those in the control group. Conclusions Application of massaging Changqiang acupuncture point could prolonge the time of uterine contraction, advance the progress of second stage of labor, and decreased the amount of postpartum hemorrhage.

Objective To discuss the influence of parturition balloon on the labor course of primi-paras. Methods We divided 160 primiparas into the observation group and the control group with 80 cases in each group.We gave the observation group parturition balloon intervention with the help of midwife. Nursing measures in the control group were the same as those of the observation group except for the appli-cation of parturition balloon. We observed and compared the psychological status,pain;labor course,dehvery manner and postpartum hemorrhage between the two groups. Results The patients in the observation group got alleviation of psychological condition and pain.The rate of caesarean operation rate,postpartum hemorrhage and time cost of labor course were shortened,which were statistically different from those of the control group(P < 0.01 ). Conclusions Nursing intervention with parturition balloon for primiparas could alleviate pain of the patients, shorten time cost of labor course,improve rate of natural parturition and de-crease caesarean operation rate.It is a service model for delivery worthy of application.
