ObjectiveTo investigate clinical effect of eradication of helicobacter pylori in patients with idiopathic thrombocytopenic purpura(ITP). Methods145 cases with HP-positive ITP paitients were divided into two groups( platelet counts results ＜ 50 × 109/L and platelet counts results ＞ 50 × 109/L). 95 cases with platelet counts ＜50 × 109/L were divided into two groups and treated with prednisone and Hp eradication(48 cases) or with prednisone without Hp eradication(47 cases). 95 cases with platelet counts ＞ 50 × 109/L were divided into two groups and treated with Hp eradication 25 cases)or follow-up without any treatment(25 cases). ResultsThe total effective rate in group treated with prednisone and Hp eradication was significantly higher than that in group with prednisone without Hp eradication( 92％ vd 75％, x2 ＝ 5.01 ,P ＜ 0.05 ). The recurrence rate in two year in group treated with prednisone and Hp eradication was significantly lower than that in group with prednisone without Hp eradication( 19％ vs 49％,x2 ＝ 9. 69, P ＜ 0. 01 ). HP eradicatiaon single can improve platelet counts in HP-positive ITP paitients.ConclusionThe detection and eradication of H pylori infection should be considered in patients with ITP. H. pylori eradication could be used for initial treatment in HP-positive ITP paitients.

Objective To explore the mechanism of therapeutic action of needle knife “regulating sinews and treating bones” on knee osteoarthritis (KOA) by observing the effect of needle knife intervention on KOA rabbit behaviors, mechanical characteristics of patellar ligament (PL), and expressions of interleukin-4 (IL-4), matrix metalloproteinase-3 (MMP-3) and aggrecan in knee cartilages.Methods Forty New Zealand rabbits were randomly allocated to blank, model, needle knife and electroacupuncture groups, 10 rabbits each. A rabbit model of KOA was made by the modified Videman method of immobilization in extension position. After model making, the needle knife and electroacupuncture groups received needle knife and electroacupuncture treatments, respectively. A behavioral assessment was made using the modified Lequesne MG knee grade evaluation method in every group after model making and treatment. The samples were taken after treatment. PL tension, stress relaxation and creep state were tested using a Bose Electro Force 3300 protracted test machine. Cartilage cell IL-4 expression was examined by ELISA. MMP-3 mRNA and aggrecan mRNA expressions were detected by real-time PCR.Results After model making, there was a statistically significant difference in the Lequesne MG score between the model and blank groups (P<0.01); there was no statistically significant difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P>0.05). There was a statistically significant post-treatment difference in the Lequesne MG score between the needle knife or electroacupuncture group and the model group (P<0.01,P<0.05) and between the needle knife and electroacupuncture groups (P<0.05). There were statistically significant post-treatment differences in PL maximum stress, maximum displacement, elastic modulus, stress relaxation rate and creep rate between the model and blank groups (P<0.01,P<0.05). There were statistically significant post-treatment post-treatment differences in PL maximum stress, maximum displacement, elastic modulus, stress relaxation rate and creep rate between the needle knife and model groups (P<0.01,P<0.05). There was a statistically significant post-treatment difference in elastic modulus between the electroacupuncture and model groups (P<0.01). The IL-4 content and aggrecan mRNA expression decreased significantly and MMP-3 mRNA expression increased significantly in the model group after model making and there were statistically significant differences compared with the blank group (P<0.01,P<0.05). After treatment, the IL-4 content increased significantly in the needle knife and electroacupuncture groups compared with the model group (P<0.01,P<0.05) and aggrecan mRNA expression tended to increase in the two groups. The regulation of aggrecan mRNA and MMP-3 mRNA expressions was better in the needle knife group than in the electroacupuncture groups, but there was no statistically significant difference compared with the model group (P>0.05).Conclusion The mechanism of action of needle knife treatment on KOA may be that it improves ligament mechanical characteristics, regulates intra-articular stress environment, and modulates aggrecan mRNA and MMP-3 mRNA expressions and inhibits cartilage degeneration through IL-4 mechanical signal pathway, to produce the therapeutic effect of “regulating sinews and treating bones”.

ObjectiveTo explore influence of emergency nursing process reengineering on the satisfac-tion degree of patients, quality of rescue, rescue time and success rate of rescue. MethodsEvidence-based nursing method was used for emergency nursing process reengineering. The first 30 types of acute and sever diseases and the first 6 large emergency events in 2008 were chosen as the rescue objectves, and they received new emergency nursing process. Influence of classic emergency nursing process in 2007 was retrieved and revalued. The satisfaction degree of patients, quality of emergency nursing and success rate of emergency before and after process reengineering were compared and analyzed. ResultsCompared with that before process reengineering, the satisfaction degree of experts, doctors and nurses, and patients was higher, the quality of emergency nursing greatly improved, the rescue time was less, and the success rate of rescue was higher after process reengineering. ConclusionsEmergency nursing process reengineering was more hu-man oriented. It can rescue patients with acute and severe diseases with lest time, reduce disputes between nurses and patients. It is worthy of application in clinic and the process should be reengineered and im-proved constantly in the future.

Objective To summarize the characteristics of ecthyma gangrenosum and explore its significance in early diagnosis of pseudomonas aeruginosa sepsis in children.Methods We retrospectively reviewed the medical records of 11 children with ecthyma gangrenosum who were hospitalized at Guangzhou women and children's medical center between May 2008 and Apr 2011.Results Eight cases were male and 7 were less than twelve months,the oldest was 2 years old,all of them were diagnosed as Pseudomonas aeruginosa spesis.Two patients had a single lesion,and the others had multiple lesions.Ecthyma gangrenosum located on the trunks in 7 cases,on anogenital areas in 5 cases,on extremities in 5 cases and on faces in 3.The lesions appeared on day 2 to day 10.On average,they developed on day 5.Seven patients developed ecthyma gangrenosum before admission,the course of the illness before admission was 6 days.Fever and multiple organ dysfunction occurred in all the patients and their cultures grew pseudomonas aeruginosa,blood cultures were positive in 8 cases,the others were isolated psudomonas aeruginosa from tissue of the lesion,discharge,ascites,pleural effusion,respectively.The time of ecthyma gangrenosum appeared was earlier than the time of the culture results reported.All of the patients were started empiric antibiotics therapy on admission,the initial antibiotic regimen was appropriate in 9 patients,8 needed surgical intervention,4 were treated with continuous blood purification.Ten patients survived and 2 died,the hospital stay was from 1 to 63 days,the average was 30.Conclusion Ecthyma gangrenosum is a known cutaneous manifestation of pseudomonas aeruginosa sepsis,which is helpful for early diagnosis and treatment,and then the outcome will be improved.

Objective To study the effect of serum leptin in “two hits” of nonalcoholic fatty liver disease (NAFLD).Methods Fasting serum leptin(LEP) ,malondialdehyde(MDA) ,hyaluronic- acid(HA) ,type Ⅲ procollagen ( PCⅢ), laminin ( LN), and type Ⅳ collagen ( Ⅳ-C ) were detected in 43 simple nonalcoholic fatty liver( NAFL ) patients ,41 NASH patients and 40 healthy subjects. Insulin resistance was estimated by HOMA value and its relatio nship with leptin level in NAFLD was analyzed. The severity of lipid peroxidation was estimated by MDA and its relationship with leptin level in NAFLD was analyzed. The relationship of serum fibrosis markers with leptin level in NAFLD also was analyzed. Results Serum leptin, HOMA value in NAFLD were higher than those of healthy controis. MDA,PC Ⅲ 、Ⅳ-C 、LN 、HA in NASH were higher than those of healthy controls or simple NAFL patients. ,HOMA value, in NAFLD positively correlated with leptin. MDA, PC Ⅲ、 Ⅳ-C 、LN、HA in NASH positively correlated with leptin. Conclusion Serum leptin closely correlated with insulin resistance which results in “First hit” of NAFLD. There was certain relationship of leptin with “Second hit” of NAFLD. Leptin should be one of the factors which result in liver fibrosis.

Objective To establish a PCR sequencing-based typing (PCR-SBT) method for simultaneous genotyping of human platelet antigen HPA-1 to HPA-16w.Methods All DNA polymorphism sites of HPA-1 to HPA-16w were obtained from the immuno polymorphism database.The specific primers were designed using Primer Premier 5.0 software to amplify nucleotide acid fragments encompassing each HPA polymorphism site.The primer sequence and PCR condition were optimized to obtain specific and single amplification product.The PCR product was purified and then sequenced to determine the HPA genotypes.Two standard DNA samples were detected using the HPA PCR-SBT method to examine the accuracy d this method.Sixteen reference samples (including 6 interference samples with HPA gene mutations) provided by 14th platelet immunology workshop of international society of blood transfusion (ISBT) in 2008 were also tested by this home-brew HPA PCR-SBT method.Results Total eleven pairs of primers were designed to amplify and sequence the sixteen HPA systems.The HPA genotypes of two standard samples were 1aa/2aa/3ab/4aa/5ab/6aa/7aa/8aa/9aa/10aa/11aa/12aa/13aa/14aa/15aa/16aa and 1aa/ 2aa/3aa/4aa/5aa/6aa/7aa/8aa/9aa/10aa/11aa/12aa/13aa/14aa/15aa/16aa,respectively.The 256 HPA genotypes of 16 reference samples were clear.128 genotypes among them were completely accordance with the results provided by ISBT report.Conclusions The PCR-SBT assay combining high-throughput DNA sequencer established in the study provides a simple,rapid and accurate method for HPA-1 to HPA-16w systems genotyping.The assay is suitable for routine clinical HPA genotyping and shows a broad prospect in further applications.

Objective To investigate the application value of functional exercise pathway in enhanced recovery of patients undergoing hepatectomy.Methods Fifty primary hepatic carcinoma patients who had undergone liver resection in Anhui Province Hospital from December 2014 to August 2015 were randomly divided into experimental group (n =25) and control group (n =25).Postoperative length of hospital stay,hospitalization charges,complications,postoperative pain score,postoperative ambulation and intestinal ventilation time were compared between these groups.Measurement data with normal distribution were represented as ((x) ± s) and comprison between groups was analyzed using the t test.Comparisons of count data were analyzed by the x2 test.Results Postoperative length of hospital stay of the experimental group [(7.00 ± 2.27) days] were shorter than control group [(9.36 ± 4.58) days] (t =3.090,P =0.003),and hospitalization expense was lower in the experimental group [(28 184.57 ± 8 675.65) yuan] (t =2.281,P =0.025).Compared with control group (40％),the experimental group (20％) had lower overall complication incidence (t =4.286,P =4.286),and general complications incidence (8％) is lower than that in control group (24％),however,the incidence of operation characteristic complications had not statistical significance in two groups.Besides,the intestinal recovery time in the experimental group was shorter than control group (experimental group 36.56 hours,control group 45.24 hours,t =2.390,P =0.019).Conclusion The application of functional exercise pathway in postoperative enhanced recovery exercise of patients undergoing hepatectomy is safe and effective,which can reduce the patients' postoperative hospital stay,hospital costs,and the general incidence of complications incidence,and be helpful for the intestinal function recovery.

Objective To understand the epidemic characteristics of an outbreak of panresistance Klebsiella pneumoniae occurred between 2006 and 2009 in a university hospital of Shanghai, China. Methods A total of 57 panresistance K. pneumoniae isolates were collected from August 2006 to December 2009.Antibiotic susceptibility of the isolates were determined by Kirby-Bauer disc diffusion method and microbroth dilution (MBD). ESBLs-producing initial screen test and phenotypic confirmatory test and carbapenemase-producing modified Hodge test ( MHT) were performed to detect the resistance phenotype of the isolates. Be-ta-lactamases were studied by IEF, PCR and the product sequencing. While conjugation assay were conducted to understand the transferability of these genes. The genetic relationship between isolates was established by ERIC-PCR and multilocus sequence typing (MLST). Except for the antibiotics recommended by CLSI guideline in the routine test, the other antibiotics were added to find out the effective drugs to treat the infection. Results All 57 isolates were highly resistant to all examined antibiotics. All isolates produced ESBLs and carbapenemase. IEF revealed that each isolate produced four beta-lactamases. All isolates carried blaKPC-2,blaCTX-M-14,blaSHV12,blaTEM-1,qnrB and aac(6') - I b-cr. Forty-four of the 57 (77.2% ) isolates were successful to transfer their resistance genes to E. coli recipient J53 by conjugation assay. By RAPD, all 57 isolates were grouped into two genotypes that were further identified as members of MUST types 423 and 11.Sequence types 423(ST423) only occurred before May 2008 and ST11 occurred (52 isolates) after May 2008. Most of isolates of the outbreak were ST11 (91. 2% ). A part of isolates were susceptive to added antibiotics. Conclusion The outbreak of panresistance K.pneumoniae was caused by those isolates which carried multiple resistant genes. There is a different ability of dissemination between different ST types K. pneumoniae isolate. It was necessary to add the antibiotics to find out the effective drugs to treat the infection.

Objective To reduce the turnaround time for laboratory diagnosis of bacteremia, the feasibility of rapid identification and susceptibility testing using samples taken directly from positive blood culture bottles was evaluated. Methods The growth of microorganisms in blood culture bottles was screened by the BACTEC 9000 blood culture system. 65 positive blood culture bottles containing gram-negative bacteria were adopted to test. Culture fluid was injected into BD SST vacutainer and centrifuged to pellet blood cells. After collecting required McFarland units, they were cultured on Phoenix 100 NMIC/ID-4(identification-gram-negative bacteria and susceptibility testing) cards using 0.25 McF and 0.5 McF methods respectively. They were also evaluated by the standard method, involving subculture tests from positive blood culture bottles. Results 63 of 65 gram-negative bacteria (96. 9% ) were correctly identified with 0. 25 McF method. 59 of 65 gram-negative bacteria(90.8% ) were correctly identified with 0.5 McF method. For antimicrobial susceptibility testing, the 0.25 McF direct method had an agreement rate more than 94% , the 0.5 McF method was more than 85.7% and direct blood sample KB method was more than 93.8% compared to the standard method. But the overall minor error rate in susceptibility testing of direct blood sample KB method is higher than other methods. Conclusion Applying 0. 25 McF and 0. 5 McF rapid identification and susceptibility test was practical. During to possessing more prominent advantages, laboratory put the 0. 25 McF direct method into practice had a timely, remarkable significance.
