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 investigate the clinical value of multiband mucosectomy (MBM) for the treatment of early esophageal cancer and precancerous lesions.Methods The clinical data of 43 patients with early esophageal cancer or precancerous lesions (including 13 cases of early esophageal cancer and 30 cases of precancerous lesion) who were admitted to the Tengzhou Central People's Hospital from January 2010 to January 2011 were retrospectively analyzed.A total of 51 lesions were confirmed by preoperative endoscopy and mucosal biopsy,and then were treated by MBM.Results A total of 52 MBM procedures were carried out,and 180 lesions were resected.The sizes of the lesions ranged from 10 mm × 8 mm to 25 mm × 23 mm,and the mean operation time was (37 ± 5)minutes.The complete resection rate was 92.2％ (47/51).The submucosal layer of 1 patient was invaded by squamous cell carcinoma postoperatively,and the patient was treated by operation;1 patient wth squamous epithelium carcinoma was treated by radiotherapy at 2 weeks after MBM ; the other 2 lesions were treated by argon plasma coagulation (APC).Four lesions with bleeding were detected during 52 MBM procedures,and no esophageal perforation was detected during MBM.Early complications consisted of delayed bleeding (1 patient,cured by APC) and slight esophageal stenosis (1 patient,recovered at postoperative month 6).The accurate rate of pathological examinations was 51.0％ (26/51).Forty-three patients were followed up for 1 year,3 patients with tumor recurrence were treated by MBM or APC.No death occurred during the followup.Conclusion MBM is a safe and effective technique for the treatment of early esophageal cancer and precancerous lesions.

Objective To study the influence on primipara's second stage of labor with the methods of Changqiang-pressing and Vaginal-pressing. Methods 180 primipara in the second stage of labor were randomly divided into 3 groups of 60 each, in which Changqiang-pressing, Vaginal-pressing and general guidance (the control group) were used respectively. The duration of uterine contraction and second stage of labor, vaginal bleeding amount in 2 hours after delivery, mode of delivery, perineal injury and birth case would be evaluated. Results The results in both Changqiang-pressing group and Vaginal-pressing group were statistically significant when compared with the control group, but there was no significant difference between Changqiang-pressing group and Vaginal-pressing group. Conclusions Using Changqiang-pressing and Vaginal-pressing can promote the progress of the second stage of labor for primipara, reduce the rate of cesarean section and neonatal asphyxia, and improve the quality of obstetric department.

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.

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.

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.
