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 develop the method for simultaneous identification and quantification of morphine,6-monoactylmorphine,codeine,heroin,ketamine,3,4-Methylenedioxyamphetamine (MDA),3,4-methylenedioxymethamphetamine (MDMA),amphetamine and methylamphetamine in human plasma.Methods UPLC-MS/MS was adopted to analyze plasma with protein precipitated using 10％ trichloroacetic acid.Plasma samples were separated on ACQUITY UPLC HSS C18 column with aqueous solution (0.01％ formic acid)-methanol (0.01％ formic acid) as the mobile phase,and at a flow rate of 0.3 mL·min-1.The multiple reaction monitoring (MRM) mode was performed combined with the positive ion mode for quantification in four sections.Results The retention time,the characteristic fragment ions,and the relative abundance ratio of the molecular ion peak could be used to identify these nine compounds sensitively.The liner calibration curve of morphine,codeine,heroin,ketamine,6-monoacetylmorphine,MDA,MDMA,amphetamine and methamphetamine were obtained in the concentration range of 5.00×10-3～5.00 (r=0.9934),1.00× 10-2～ 10.00 (r=0.9905),1.00× 10-2～ 10.00 (r=0.9929),2.50× 10-3 ～2.50 (r=0.9960),5.00× 10-3 ～ 5.00 (r=0.9925),5.00× 10-4 ～ 5.00 (r=0.9910),5.00× 10-4 ～ 5.00 (r=0.9924),5.00× 10-4 ～ 5.00 (r=0.9920) and 5.00×10-4～5.00 μg·mL-1 (r=0.9900) respectively.The lowest detection limit was 1.00,1.00,1.00,0.50,0.50,0.10,0.10,0.10 and 0.10 ng· mL-1 respectively.The relative standard deviation (RSD) of the inter-day and intra-day were less than 18％.The relative recovery was more than 60％,and the RSD were less than 15％.Conclusion The method is accurate,sensitive and suitable for identification and quantification of 9 drugs of opiates,ketamine and amphetamines in human plasma.

Objective To analyze the effects of the mumps virus on testicular function and evaluate the value of blood testosterone in acute orchitis condition and prognosis by observing the testosterone levels of peripheral blood in the mumps orchitis patients.Methods Thirty patients with acute mumps orchitis (mumps orchitis group)and 28 patients with mumps only without any major complications (mumps group)were enrolled in the study.At the same time,we selected 20 healthy males in our hospital as healthy controls.All cases were treated by ribavirin (10mg/kg). The testosterone was tested by chemiluminescence method,in 0,7,14 days respectively.The variance analysis and LSD -t test were used to compare differences of blood testosterone in each group,and Pearson method was used to analyze the correlation of blood testosterone and testicular swelling day times,blood amylase,level of neutrophils,IL -6 and CRP.Results The testosterone of acute orchitis [(1.51 ±0.26)ng/mL]was lower than mumps group and healthy controls.The difference was significant(F =99.36,P <0.01).The level of blood testosterone was significantly increased in the treatment for 14 days (t =13.03,P <0.01),and there was no significant difference compared with healthy controls (t =1.23,P =1.23).Pearson correlation analysis found that blood testosterone levels were negatively correlated with the days of testicular swelling,the levels of IL -6 and CRP(r =0.678,P <0.01 and r =0.528,P =0.000;r =0.442,P =0.000).Conclusion This study showed that MuV infection inhibited testosterone synthesis in Leydig cells.In other words,the level of blood testosterone is related to the severity of the orchitis,which can be widely used in clinical.

I. Under scanning electron microscope, the vascular network of the cutaneous, subcutaneous, and deep fascia in planta can be divided into five layers according totheir vascular morphological characteristics. They are as following: the papillary layer, the subpapillary layer, the deep dermal layer, the subcutaneous layer, and the deep fascia layer. 2. The papillary layer is the most superficial one, it is easy to recognize that there are five types of capillary network: the single loop, the multiple loop, the tower-like type, the finger-like type, and irregular type. 3. The network in the subpapillary layer is polygon-like, parallel to the surface of skin. 4. In the deep dermal layer, there are many vascular balls in the vascular trunks. 5. The subcutaneous layer: The vascular networks are limited by fat lobules. 6. The vascular-trunks run across each other and anastomose each other in deep fascia layer.

On the basis of systematicly reviewing the developmental history of acupuncture and moxibustion and profoundly understanding its academic connotations,the authors of the present article make a summary and analysis on the key factors influencing the development of acupuncturology. These key factors are 1) the emergence of "microacupuncture needle regulating-Qi" and the establishement of their corresponding theory system,2) a large number of practitioners who inherited the learnings of acupuncturology generations by generations,and abundant medical classical works which recorded the valuable academic thoughts and clinical experience of the predecesors,3) the application of acupuncture charts and manikins,and 4) modernizing changes of acupuncture learnings after introduction of western medicine to China. Just under the influence of these key factors,the acupuncture medicine separates itself from the level of the simple experience medicine,and has formed a set of special theory system and developed into a mature subject.

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 LOH at regions on chromosomal arm 8p22,11p15,17p13 and its relationship with clinicopathological parameters. Methods:Thirty-four paraffin-embedded tumor and corresponding noncancerous tissues were analysed. PCR was used to amplified three microsatellite markers D8S136,D11S988 and TP53 located at these chromosomal regions. PCR products were electrophoresed on 6%polyacrylamide gel and detected using silver staining. The P53, c-erBb-2,PR,ER status were determined by immunohistochemistry. Results:Of the three markers we studied, D8S136 was detected LOH at a frequency of 12 in 34 tumors(35.29%). D11S988 and TP53 were detected LOH at a frequency of 5 in 34 tumors(14.71%). There were no obvious associations between LOH at D11S988、TP53 and clinicopathological parameters, but the tumors with LOH at D8S136 were significant larger than that without LOH(P=0.0049). Conclusion: Invasive ductal carcinoma of the breast has a frequent LOH on chromosome 8p22. The loss or inactivation of putative tumor suppressor genes on 8p22 may contribute to the excessive growth of the tumors.

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.
