Objective To understand a cancer hospital inpatient care Ningxia quality of service perceived status quo.Methods Servqual model-based,self-designed Expect Inpatient Nursing Service Quality Perception Questionnaire was used to investigate 160 hospitalized patients and expected to build expectations oncology inpatients quality of care and services-dimensional perception matrix (IPA matrix).Results By analyzing sensible quality (SQ) value and IPA matrix of the Servqual questionnaire,all items except for treating equally and recommend the hospital showed SQ＜0,that was,the actual feelings of patients were less than expected,and there was statistical difference between the actual feelings and expected feelings in the quiet ward,health guide,care level (t=2.963,2.020,2.020,P ＜0.05).IPA matrix showed that ward quiet,health guidance,care level was the priority problems for the hospital.Life Care,protection of privacy,psychological care,level of service,pay the money reached care were the minor priority problems.Conclusions Servqual Model and IPA matrix combination can help to understand the gap between expectations and perception of nursing service,identify problems improvement priorities,identify weaknesses in care for hospital managers,and develop fine effective theory.

Paeoniflorin is the main active ingredient of Chinese herbaceous peony. This study is to investigate the protective effect of paeoniflorin (Pae) on acute brain damage induced by lipopolysaccharide (LPS) in mice. The mice were randomly assigned to the normal control, model control (LPS), as well as groups of paeoniflorin and lipopolysaccharide (Pae + LPS). Then the mice were administered intraperitioneally with normal saline or Pae (10, 30 mg · kg(-1)) once daily for 6 d. One hour after intrapertioneally treatment on the seventh day, each group were injected LPS (5 mg · kg(-1)) to establish the endotoxin lipopolysaccharide inflammation model except the normal group. The mice were sacrificed after 6 h and the brain homogenates were prepared and measured. The malondialdehyde (MDA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), total antioxidant capacity (T-AOC), hydrogen peroxide (H2O2), succinatedehydrogenase (SDH), Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase were dectected by the colorimetric method. The levels of HO-1 and Nrf2 protein in subcellular fractions of brain tissue were detected by Western blot. The results demonstrated that the administration with paeoniflorin reduced the levels of the MDA production; significantly increase the activities of antioxidant enzyme (SOD and GSH-PX). In addition, paeoniflorin could enhance the total antioxidant capacity, decrease the level of H2O2, and increase the activities of SDH, Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase. Furthermore, paeoniflorin can increase the expression of HO-1 and activate the nuclear transfer of Nrf2. Taking together, these findings suggest that paeoniflorin alleviate the acute inflammation in mice brain damage induced by LPS, which is related with its antioxidant effect and improvement of energy metabolism.

Tripterygium glycosides preparation which extracted from the traditional Chinese herb Tripterygium wilfordii (TWHY), was widely used to treat the autoimmune diseases. Previous works demonstrated that TWHF had potent anti-inflammatory and immunosuppressive properties. But the different quality and high incident rate of side effects of different manufactures inhibited its clinical application. Since TWHF had been generally known to play a therapeutical effect by synergism of multiple constituents, it was necessary to build the relationship between the HPLC fingerprint and bioactivity so as to ensure the quality safety and efficacy. The HPLC fingerprint showed that description and content of peaks from different manufactures were diverse. Only 11 common peaks were found. In this study, mice spleen cells stimulated by Con A were used to test the proliferation inhibition bioactivity of TWHF preparations, which were incubated with 30, 15, 7.5, 3.75, 1.88 and 0.94 mg x L(-1) TWHF preparations for 48 h. The results showed that mice spleen cells proliferation was inhibited by all TWHF preparations significantly compared with the control group, which suggested the TWHF preparations showed immune suppress activity. The TWHF preparations from 7 manufacture showed different IC50 value, which might belong to different contents which showed in the HPLC fingerprint. Moreover, a relationship between the HPLC fingerprint and the bioactivity were established to identify important constituents by grey relational analysis (GRA). The result showed that all the contents were relative with the IC50, especially No. 5 and 10 peaks, but No. 1 peak, which was proved to be triptolide, had few contribute to the inhibition of mice spleen cells proliferation. The study of relationship between the HPLC fingerprint and the IC50 by GRA could help to investigate mechanism of bioactive and provide an evidence for the quantification of multi-constituents.

BACKGROUNDThe study was designed to investigate the status of molecular epidemiology of HCMV in Urumqi through genetic comparison of clinical isolates.

METHODSDNA sequences of 2.0-2.6 kb were amplified by polymerase chain reaction from three relatively conservative gene regions (DNA polymerase, glycoproteins H, and major immediate-early antigen) of 28 clinical HCMV strains and then were analysed by restriction enzymes.

RESULTSThe restriction patterns of the clinical isolates which did not have relation in epidemiology were greatly different, but the patterns of the clinical isolates related in epidemiology such as strains paired in mother and infant were quite similar. Of eight mother and infant pairs, from whom HCMV were isolated, four pairs showed identity of restriction profiles within each pair for all three amplified regions, four pairs showed differences between mother and infant.

CONCLUSIONThese results confirm the high degree of genetic variability among cytomegalovirus strains in Urumqi. Analysis of PCR-RFLP can indicate transmission of HCMV infection and facilitate its molecular epidemiologic studies.

Objective To study the sleep improvement function of DHA-PC.Methods The mice were randomly divid-ed into control, vehicle, DHA+Lecithin (60+200 mg/kg) and DHA-PC(50,100,200 mg/kg) groups.Ten mice were enrolled in each group .The mice of control were administered with normal food , the vehicle group was orally given normal saline at the dosage of 0.2 ml/10 g, while both DHA-PC and DHA+Lecithin were orally given corresponding drugs at the dosage of 0.2 ml/10 g.All the groups were treated for 30 days except control group .The direct sleep-inducing test, the test of lengthening sleep time induced by pentobarbital sodium , the test of pentobarbital sodium subthreshold-hypnosis and the test of barbital sodium sleep latency were conducted to observe the inductive effect of DHA -PC.Results Neither the effect on mice body mass nor directly-induced sleep was observed .DHA-PC (50,100, and 200 mg/kg) could prolong sleep time to (56.2 ±13.7),(57.9 ±25.4) and(64.1 ±18.4) min, respectively,compared to vehicle(32.9 ±10.8)min (P<0.05).DHA+Lecithin could not prolong sleep time (38.6 ±11.7)min compared to (32.9 ±10.8)min of vehicle.There was significant difference compared with DHA-PC at the dosage of 200 mg/kg (64.1 ±18.4)min (P<0.05).DHA-PC (200 mg/kg) enhanced pentobarbital sodium subthreshold-hypnosis (70%) compared to vehicle (10%) (P<0.05),so did DHA+Lecithin (60%) compared to vehicle (10%) (P<0.05).Both DHA-PC (200 mg/kg)[(22.9 ±4.1)min ] and DHA+Lecithin [(19.5 ±2.7) min ]could shorten sleep latency compared to vehicle (31.3 ±6.9) min(P<0.01), and the sleep latency of DHA +Lecithin (19.5 ±2.7) min was shorter than that of DHA-PC(50,100 mg/kg).Conclusion DHA-PC has some effect some sleep improvement in mice .

To construct knockout vectors containing ampicillin resistant gene and partial sequence of hyaluronidase gene(Hyl)so that Hyl can be knock out by transforming the plasmid into Streptococcus zoopidemics mutans.First,partial sequence of Hyl(Hyl-1)was cloned into the vector of pMD19-T by using DNA of Streptococcus zoopidemics as template,and then a knockout vector pMD19T-SA was constructed,in which Hyl-1 gene was disrupted by inserting ampicillin resistant gene(Amp)from reverse PCR.As expected,the vector was proved to be consisted of Hyl-1-Amp-Hyl-1-pMD19-T.Thereafter,DNA fragment of Hyl-1-Amp-Hyl-1 was subcloned into pBR322 vector,the resulting construct was then checked by PCR and restriction analysis for the proper configuration of the knockout vector pBR322-SA.Both of the knockout vectors were used to transform Streptococcus zoopidemics and one recombinant was obtained in result.From results of PCR and Hyl activity assay,it was indicated that in the recombinant the Hyl gene was disrupted completely.

OBJECTIVETo discuss the effect of Taohong Siwu Decoction (TSD) in regulating functions of endothelial cells and treating arteriosclerosis obliterans (ASO).

METHODSThe ASO model was prepared by using high-fat diet plus intimal injury. They were randomly divided into the model group (n = 10), the normal control group (n = 9), the low dose TSD group (group A, n = 12), the middle dose TSD group (group B, n = 10), and the high dose TSD group (group C, n = 9). Eight weeks after modeling, the limb blood perfusion was observed using laser Doppler flowmetry. The arterial morphology was observed using light microscope and transmission electron microscope. The number of circulating endothelial cells (CECs) was determined using Percoll density gradient centrifugation method. Serum levels of TNF-alpha, IL-1, ET-1, and NO were detected using double antibody sandwich assay of enzyme linked immunosorbent assay (ELISA).

RESULTSThe ASO rat model was successfully established. Blood lipids levels significantly increased, the blood perfusion of left hind limbs significantly decreased, the number of CECs in the peripheral blood significantly increased, the arterial lumen was irregularly narrowed, the ultra-structure of vessel walls was damaged, serum levels of TNF-alpha, IL-1, and ET-1 significantly increased, and the serum level of NO significantly decreased in the model group, showing statistical difference when compared with the normal control group (P < 0.01). Compared with the model group, significant improvement in the aforesaid indices was shown in group B and C (P < 0.05, P < 0.01).

CONCLUSIONSThe injury and abnormal functions of endothelial cells is an important pathological process of ASO. As an effective recipe for treating ASO, TSD could protect vascular endothelial cells and improve the secretion function of vascular endothelial cells.

Nonunion of femur is a common complication after intramedullary nail operation of femoral fracture, with an incidence of 1% to 12.5%. At present, the treatment of femoral nonunion is mainly divided into surgical treatment and non-operative treatment, and surgical treatment is the first choice. The gold standard for surgical treatment of femoral nonunion is replacement of intramedullary nail, but for non-isthmus femoral nonunion, larger diameter intramedullary nail could not solve the problem of rotation and angular displacement of the broken end of nonunion. For malnourished nonunion, atrophic nonunion and bone nonunion with large bone defect, the replacement of intramedullary nail and autogenous bone graft are not enough to eliminate the gap between the broken ends and increase the contact area between the broken ends. It cannot provide a good biological environment for the broken ends. Because the replacement of intramedullary nail does not expose the broken ends of bone nonunion, and the corresponding tissue cannot be taken for bacteriological culture, so it is difficult to judge whether the broken end sare complicated with infection. The double plate technique is to find the site of bone nonunion under direct vision, and two plates are placed with different angles. This paper reviews the literature related to the treatment of femoral nonunion with double plate technique published at home and abroad in the past 10 years, and concludes that double plate fixation combined with autogenous iliac bone graft provides a three-dimensional fixation model for the healing of nonunion. It has the characteristics of strong stability and plays an active role in improving the biological behavior and mechanical stability of the fracture ends. The operation is beneficial to the flexion and extension of the knee joint, with the characteristics of high healing rate, low complication rate, effective pain relief and so on.

Objective To establish competent characteristic system and a level standard model for orthopedic specialized nurses.Methods From October 2016 to March 2017, a total of 40 medical and nursing specialists from 10 provinces and cities were selected by convenience sampling methods as specialist consultants. Two rounds of Delphi specialist consultation were conducted on 7 primary indexes and 58 secondary indexes of the competent characteristic system for orthopedic specialized nurses which was primarily confirmed by literature search. The index names were modified, merged or deleted according to experts' opinion and statistical analysis results. At last, 12 experts in Beijing area were selected, and the typical behavior event interview method was adopted to determine the level standards of the secondary indexes.Results The experts' authority coefficient was 0.91. The effective recovery rates of questionnaires of the two rounds expert consultation were 95.00％ and 92.11％ respectively. The primary indexes consists of 7 indicators: clinical decision (0.1500), nursing practice (0.1543), management (0.1356), communication(0.1422), legal ethics(0.1289), professional development (0.1364) and education(0.1322). Twenty-eight items of secondary index were confirmed, and Likert Scale was applied to determine the level standards of secondary index and describe typical behavior. Level 1 to 5 of Likert Scale was corresponding to the levels to orthopedic specialist nurse's career planning respectively, including entry-level, qulified, competent, proficient, and expert level.Conclusions The evaluation indicators recommended in specialist consultation meet the specialized nurse competent characteristics, and quantitative evaluation of specialized nurses can be achieved by the level standard system. The evaluation and level standard system can analyze the strengths and weaknesses of the subjects, to achieve evaluation, education, management and career planning for orthopedic specialized nurse.
