Objective:To establish nursing quality indicator system for freestanding hemodialysis facilities and identify the weight values of indicators.Methods:With the structure-process-outcome quality model as the framework, the literature analysis method, field survey and semi-structure interview were used to form the indicators item pool. Through Delphi method, experts were consulted for two rounds. The indicator weight was calculated by AHP.Results:The indicator system of this study included 3 primary indicators, 15 secondary indicators and 46 tertiary indicators. Among the primary indicators, the process quality indicator had the largest weight (0.493), followed by the outcome quality indicator (0.310), and the structure quality indicator had the smallest weight (0.196).The process quality were the main evaluation contents. According to the indicator weight, the main manpower allocation (0.131) in secondary indicators had the highest weight, and the proportion of nurses with different hemodialysis work experiences (0.108) in the tertiary indicators had the highest weight.Conclusion:The indicator system of this study is scientific and integrated, which can be used as a nursing quality evaluation tool to verify its practicability in clinical nursing practice.

Objective To explore the protective effect of a small balloon on bifurcation lesions by applying a single stent treatment of coronary bifurcation lesions strategy. Methods Fifty patients with coronary bifurcation lesions were randomly divided into A group and B group( 25 cases for each group ). Patients in A group were treated with the pre-entry protection branch guide wire to complete the main branch balloon pre-dilation,stenting,while in B group were treated with the set aside the branches of a small balloon. The information of main branch balloon pre-dilation,stenting were recorded. The blood flow slowed down,the incidence of side branch occlusion or stent placement,and the incidence of postoperative 24 h troponin I( cTnI) levels were measured. Results Nine cases(36%)in A group occurred lower branch blood flow,which due to 4 cases(16% )with significantly narrow branch stenting,2 cases(8%)with complete occlusion. There were only 2 cases(8%)with decrease branching blood flow in B group,and the difference was significant(P=0. 041, 0. 022). The cases with higher cTnI after 24 h in A group were 11( 39%),significantly higher in group B (3(12 %);P =0. 027 ). Conclusion Compared with the traditional protection guidewire,the approach of setting aside a small balloon to protect important branch can effectively prevent important branch occlusion, branch involvement due to lower incidence of myocardial infarction.

Objective To investigate the clinical skill and experience of laparoscopic herniorrhaphy in the treatment of abdominal hernia.

Objective To explore the application of single-person operated mammotome minimally inva-sive surgery in treatment of benign breast lesions. Methods Clinical information of 403 patients were collected and retrospectively analyzed. 262 patients receiving ultrasound guided single-person operated mammotome mini-mally invasive surgery for benign breast masses were selected as the treatment group,141 patients undergoing open surgery for treatment of benign breast masses were selected as the control group.Operative time, introopera-tive blood loss,length of stay,postoperative healing time, as well as the occurrence of complications were com-pared between the two groups. Result Compared with the control group, the operative time was shorter, the in traoperative blood loss was less, the scar size and the postoperative healing time were shorter for the treatment group. The difference had statistical significance (P<0.05).The rate of postoperative pain, local ecchymosis, local infection and breast deformity for the treatment group was significantly lower than those of the control group (P<0.05). The difference had statistical significance (P<0.05). The recurrence rate between the two groups had no sta-tistical significance (P>0.05). Conclusions Single-person operated Mammotome minimally invasive surgery has the advantages of good operative time,good cosmetic effects, small surgical trauma, less blood loss, fast postoper-ative healing and few complications, which is worthy of clinical application.

Objective To explore the influence of hematopoietic growth factors on the TBI patients in the conditioning regimen for stem cell transplantation,and to evaluate the effect of cytokines on treatment of acute radiation disease.Methods The usage of hematopoietic growth factors,implantations and the side-effects of the patients and donors of TBI in the conditioning regimen for stem cell transplantation were retrospectively analysed from 1990 to 2012,and the effect and side-effects of cytokines on the hematopoietic function recovery and stem cell mobilization were observed.Results All patients recovered from their hematopoietic function except one died due to the side-effecs.The median time of white blood cell recover was 10 d in auto-SCT and 12 d in allo-SCT in the G-CSF group.The median day of platelet recovery was 11.67 ± 1.53 in rhIL-11 arm and 13.70 ±6.27 in no rhIL-11 arm in the auto-SCT group.The incidence rates of dental ulcer and diarrhea in the TBI patients were 48％ and 44％,respectively.The occurrence of side-effect was rare in the period of cytokines treatment,but was over 50％ during stem cell mobilization.Conclusions Cytokines play very important roles in the hematopoietic function recovery and stem cell mobilization in the TBI patients.

This study aimed at evaluating the quality of the precise powder decoction pieces (PPDP) of L.japonicae Flos (LJF) compared with the traditional commercial slices with chemical fingerprint methods and DNA molecular identification technology.Different specifications of PPDP were prepared,their dry extract contents were in contrast with that of commercial slices.The three batches of commercial slices were collected,and the content uniformity,fingerprint and similarity evaluation before and after the mixing and pulverization were studied by HPLC-DAD and DNA sequence alignment.As a result,the paste rate of PPDP was slightly higher than that of the traditional commercial slices.The dissolution of chlorogenic acid of PPDP was higher than that of the traditional commercial slices.RSD of inter-assay dissolutions of chlorogenic acid of commercial slices was 11.93％,which was reduced to 8.29％ after mixing and preparing into PPDP.The fingerprint showed that the slimilarity of the fringerprint of the mixed and powdered LJF was elevated with 7 common peaks.All the common peaks were increased at different levels.In conclusion,compared with traditional commercial slices of LJF,PPDP apparently improved the dissolution rate and the quality uniformity,indicating that the boiled powder of CRP obviously presented vantages in clinic.

OBJECTIVETo test the different contrctile responses of extracellular nucleotides, such as ATP, UTP and nucleotide uridine adenosine tetraphosphate (Up4A) in gastric longitudinal muscle (LM) and circular muscle (CM). Examined the effect of P2X and P2Y receptor antagonists (in this study, we used IP5I and suramin) and cyclooxygenase inhibitor (indomethacin) on Up4A induced contractile responses in LM and CM.

METHODSThe rats were sacrificed and the stomachs were opened to gain LM and CM. Using organ bath system to assess contrctile responses of smooth muscle.

RESULTSUp4A could induce contractile responses in both CM and LM, which were similar with ATP and UTP. IP5 did not attenuate Up4A could induce contractions in both LM and CM, but suramin and indomethacin significantly inhibited Up4A contraction in CM, but not in LM.

CONCLUSIONOur results suggest that extracellular nucleosides and their inhibitors induce different responses between LM and CM.
