Objective The purpose of the study was to identify the most frequently used nursing diagnoses,interventions,outcomes and linkages using standardized nursing terminologies for elderly patients with abdominal external hernia surgery.Methods For this study a descriptive design was used.The frequently used NANDA-Ⅰ,NIC,NOC,and NNN linkages were identified through 38 elderly patients with abdominal external hernia surgery who were admitted in hospital from March to August in 2014.Data were analyzed by SPSS17.0.Results The finding showed the most frequently used 5 nursing diagnoses were activity intolerance,impaired tissue integrity,deficient knowledge,chronic pain,and risk for falls,the frequency were 15.51％(38/245),15.51％(38/245),15.10％(37/245),14.69％(36/245) and 14.69％(36/245),the most frequently used 5 nursing outcomes were activity tolerance,ambulation,tissue integrity (skin and mucous membranes),wound healing (primary intention) and knowledge (diet) the frequency were 10.05％(38/378),10.05％(38/378),10.05％(38/378),10.05％(38/378) and 9.79％(38/378); the most frequently used 5 nursing interventions were environmental management (comfort),positioning,exercise therapy (ambulation,) incision site care and environmental management the frequency was all 6.96％(38/546).The most frequently used top 10 NNN linkages were also identified in this study.Conclusions The most frequently used NANDA-Ⅰ,NIC,NOC,and NNN linkages for patients with abdominal external hernia surgery from this study not only offer new knowledge to nurses but also provide scope of evidence-based nursing research in abdominal external hernia clinics.

Objective To investigate the clinical treatment strategy of concomitant diseases and perioperation complications in elderly patients with hip fracture aged ≥ 80 years and the clinical prognosis.Methods A retrospective analysis was conducted in 95 hip fracture patients aged 80 and over years(80～90 years old) undergoing operation.There were 42 cases with femoral neck fractures and 53 cases with intertrochanteric fracture.71 cases (74.7％) had preoperative concomitant medical diseases.Screw fixation was performed in 3 cases (3.2％),hemiarthroplasty in 75 cases (78.9％),total hip replacement in 4 cases (4.2％),proximal femoral nail antirotation (PFNA) in 9 cases (9.5 ％) and reconstruction interlocking nail fixation in 4 cases (4.2 ％).Results No mortality was found during hospitalization.Postoperative anemia was the most common (74.7％),followed by hypoproteinemia (68.4％),digestive disorders (30.5％),electrolyte disturbance (28.4％) and psychiatric symptoms (15.8 ％).At least one-year follow-up was made in 73 cases.39 cases (53.4 ％) acquired independent activities after surgery,48 (65.8％) patients recovered to the preoperative level of activity.The concomitant diseases before surgery (OR =0.23,P =0.011),preoperative ability of activity (OR=0.23,P=0.025),the American Society of Anesthesiology (ASA) classification (OR=0.19,P=0.025) were the related factors influencing the one-year mortality.Conclusions The treatment of concomitant diseases should be emphasized in treating fracture.The active prevention during preoperative,intraoperative,postoperative period could reduce or avoid fatal complications and acquire good functions.

Objective: To observe the joint effect of school and family tobacco control on middle school students, and to explore its effectiveness in reducing second-hand smoke exposure in middle school students’ families, as so asto provide a new way of thinking for controlling smoking among middle school sudents. Methods: A questionnaire survey was conducted on the study of 2 125 primary and high school students in four middle schools in the Dongcheng District of Beijing by means of a stratified group sampling method. Personal information of students, tobacco control environment around the family, school and surrounding ares, as well as the knowledge, attitude and behavior of students related to tobacco control was collected. Results: The exposure rate of second-hand smoke in the families of middle and high school students in Dongcheng District of Beijing was 33.41%. Smoking by at least one parent was positively correlated with second-hand smoke exposure in the student’s home (OR=22.88, P<0.05). Among the students who saw the "clear no-smoking label" on campus, the exposure rate (4.92%) when the smoking restriction was set on the home was lower than that of those who did not have a regulation in the home (58.94%) (χ2=452.57, P<0.01). The results of Logistic regression showed that there was a combination of family smoking restrictions and second-hand smoke exposure in middle and high school students who had seen the smoking ban on campus (OR=0.08) and had the school’s tobacco control education (OR=0.08). Conclusion The joint tobacco control measures between school and family can effectively reduce the exposure rate of second-hand smoke in middle school students’ families, which is better than the effect of tobacco control alone.

OBJECTIVETo explore if CHA2DS2 VASc score can predict substrate for persistent atrial fibrillation ( AF) and outcome post catheter ablation of AF.

METHODSFrom January 2011 to December 2012,116 patients underwent catheter ablation of persistent AF in our department and were enrolled in this study. CHA2DS2VASc score was calculated as follows: two points were assigned for a history of stroke or transient ischemic attack and age ≥ 75 and 1 point each was assigned for age ≥ 65, a history of hypertension, diabetes,recent cardiac failure, vessel disease, female. Left atrial geometry ( LA) was reconstructed with a 3.5 mm tip ablation catheter with fill-in threshold 10 in CARTO system. The mapping catheter was stabled at each endocardial location for at least 3 seconds for recording. The electrogram recordings at each endocardial location were analyzed with a custom software embedded in the CARTO mapping system. Interval confidence level (ICL) was used to characterize complex fractionated atrial electrograms (CFAEs) . As the default setting of the software, ICL more than or equal to 7 was considered sites with a highly repetitive CFAEs complex. CFAEs index was defined as the fraction of area of ICL more than or equal to 7 to the left atrial surface. The CFAEs index and outcome of catheter ablation among different CHA2DS2VASc groups were compared.

RESULTSOf the 116 patients, CHA2DS2VASc was 0 in 33 patients, 1 in 31 patients and ≥ 2 in 52 patients. Left atrial surface ((121.2 ± 18.9) cm2, (133.6 ± 23.8) cm2, (133.9 ± 16.1) cm2, P = 0.008), left atrial volume ((103.6 ± 24.8) ml, (118.3 ± 27.8) ml, (120.9 ± 20.9) ml, P = 0.005) and CFAEs index (44.6% ± 22.4%, 54.2% ± 22.2%, 58.7% ± 23.1%, P = 0.023) increased in proportion with increasing CHA2DS2VASc. ICLmax, ICLmin and CFAEs spatial distribution were similar among the three groups. During the mean follow-up of (13 ± 8) months, the recurrence rate were 36.4%, 35.5%, 55.8% among the three groups (P = 0.025).

CONCLUSIONA high CHA2DS2VASc score is associated with extensive AF substrate and higher recurrence rate post catheter ablation of persistent AF.

Objective: To evaluate the therapeutic efficacy and safety of immunosuppressive therapy (IST) combined with recombinant human thrombopoietin (rhTPO) for severe aplastic anemia (SAA) in pediatric patients. Method: A retrospective case-control study was conducted and the clinical data of 45 pediatric patients with de novo SAA admitted to the Anemia Diagnosis and Treatment Center of Chinese Academy of Medical Sciences & Blood Disease Hospital during the period from December 2009 to December 2014 were analyzed. Among them, 15 patients were treated with the regimen of IST together with rhTPO and 30 patients were given IST treatment only. The variation characteristics of the peripheral blood routine as well as the transfusion of blood products was dynamically observed, and the therapeutic efficacy was assessed respectively after 3, 6 and 12 months after the treatment. In the meantime, adverse effects related to rhTPO application were recorded. Thereafter, the statistics of the two groups were compared by non-parametric rank sum test. Result: Among 45 pediatric patients, there were 26 male and 19 female, and the median age was 11 years (6-14). The number of patients received good hematological response(complete remission (CR) plus good partial response (GPR)) in the combinatory group versus vs. the IST group was 6 vs. 3 patients (χ²=3.906, P=0.048) at the 3rd month, 7 vs. 7 patients (χ²=1.568, P=0.210) at the 6th month, and 13 vs. 14 patients (χ²=6.667, P=0.01) at the 12th month respectively. For those achieved good hematological response at the 3rd month, the amount of platelets transfusion and red blood cells transfusion of the combined group were both less than that of the IST group during the period from the 10th to the 12th weeks (platelets transfusion: 1.4 U vs. 2.9 U, t=-3.523, P=0.002; red blood cells transfusion: 0.8 U vs. 2.6 U, t=-2.392, P=0.026). No serious adverse effect related to rhTPO application was observed in the IST combined with rhTPO group. Conclusion Application of rhTPO can improve the short-term therapeutic efficacy of IST for pediatric SAA, alleviate transfusion dependence, and has a good safety profile.

OBJECTIVE：  To improve the method for the content determination of astragaloside Ⅳ in Xiangju granules， and to evaluate the consistency of relevant preparations with the components of original formulation， so as to provide evidence for the modern preparation of TCM compound. METHODS： HPLC-ELSD method was established for the content determination of astragaloside Ⅳ in Xiangju granules， and compared with original standard TLC scanning. Using critrinin， ferulic acid， calycosin glucoside， liquiritin， glycyrrhizic acid， rosmarinic acid， buddleoside and magnoline as control， HPLC method was used to determine the release components of self-made Xiangju granules， Xiangju capsules， Xiangju tablets in water. Fingerprint characteristics chromatogram of different Xiangju preparations and original formulation extract were compared by using Similarity Evaluation System for Chromatographic Fingerprint of TCM （2012 version）. At the same time， HPLC-ELSD method was used to determine and compare the release rate of astragaloside Ⅳ from different Xiangju preparations and original formulation extract in water. RESULTS： Established HPLC-ELSD method was specific. The linear range of astragaloside Ⅳ was 0.13-2.10 mg/mL. RSDs of precision， repeatability and stability tests were all lower than 3％ （n＝6）， and average recovery was 97.66％ （RSD＝1.01％，n＝6）. Average content of astragaloside Ⅳ by this method was 0.398 mg/g （RSD＝1.01％， n＝3）， which had better reproducibility than TLC scanning. The comparative results of characteristic fingerprints showed that the similarity among Xiangju granules， Xiangju capsules， Xiangju tablets and the original formulation dry extract powder was more than 0.850. Average release rates of astragaloside Ⅳ in Xiangju granules， Xiangju capsules， Xiangju tablets and the original formulation extract were 0.392， 0.358， 0.349， 0.389 mg， respectively. Compared with original formulation extract， there was no statistical significance in release rate of astragaloside Ⅳ in Xiangju granules （P＞0.05）， while there was statistical significance in Xiangju capsules and Xiangju tablets （P＜0.01）. CONCLU- SIONS： Established HPLC-ELSD method is accurate and feasible， and is suitable for the content determination of astragaloside Ⅳ in Xiangju granules. The main components of Xiangju granules are consistent with original formulation.

Objective: To investigate the clinical and microbiological characteristics of Myroides odoratimimus producing MUS-1 carbapenemase. Methods: A strain of gram-negative bacterium isolated from the urine sample of one patient hospitalized in the oncology department of Affiliated Hospital of Xuzhou Medical University was identified by the Vitek 2 automatic microbial analyzer and 16S RNA sequencing, and its bla MUS-1 gene was detected with PCR. The minimum inhibitory concentrations (MICs) of antimicrobial drugs were determined by the broth dilution method. Results: One strain of MUS-1 carbapenemase producing Myroides odoratimimus was found. The drug susceptibility test showed that it was resistant to most of antibiotics conventionally used, but sensitive to minocycline and meropenem, the MIC of imipenem was 8 μg/mL, which was judged as intermediate. Conclusion The bla MUS-1 gene may be the cause leading Myroides odoratimimus to resistant carbapenems drugs.

OBJECTIVE To investigate the effect and potential mechanism of sodium ferulate （SF） on corneal endothelial dysfunction and corneal endothelial cell （CEC） injury. METHODS The male New Zealand rabbits were divided into control group， benzalkonium chloride （BAK） group and BAK+SF group， with 6 rabbits in each group. Except for control group， the other groups were given BAK into the anterior chamber to induce bullous keratopathy model， and BAK+SF group then given SF solution 200 mg/kg intraperitoneally the next day after surgery， twice a day， for consecutive 14 d. The transparency of corneal and edema of corneal stroma in each group of rabbits （before and on the 1st， 7th， and 14th day after surgery） were observed， and the corneal thickness （14th day after surgery） and intraocular pressure （1st to 14th day after surgery） were measured. On the 14th day after operation， the corneal endothelial structure was evaluated and the expressions of functionally related proteins [phalloidin， zonula occludens-1 （ZO-1）， Na+/K+-ATPase， Ki67] were detected. On the 14th day after surgery， the corneal tissue was collected in BAK group， the primary rabbit CECs were isolated and cultured， and they were divided into blank group and SF groups with different mass concentrations. The cell viabilities after being cultured for different time， and the protein expressions of Ras homologous gene family A （RhoA）， bone morphogenetic protein receptor 1A （BMPR1A） and BMRP2 were determined in each group. RESULTS Compared with BAK group， the transparency of corneal and edema of corneal stroma were gradually improved， and the corneal thickness was significantly decreased in BAK+SF group （P＜0.05）. The rabbit CECs in BAK+SF group were only damaged to zone B and showed a normal hexagonal endothelial cells structure. The protein expressions of phalloidin， ZO-1， Na+/K+-ATPase and Ki67 in BAK+SF group were significantly increased （P＜0.05）. When SF concentration was lower than and equal to 200 mg/L， it could promote the proliferation of rabbit CEC， in concentration manner （P＜0.05） and time-dependent trend. SF at concentrations of 50， 100， and 200 mg/L could up-regulate the protein expressions of RhoA， BMPR1A and BMPR2 in concentration-dependent manner （P＜0.05）. CONCLUSIONS SF can improve the transparency of corneal and edema of corneal stroma in bullous keratopathy model rabbits， reduce corneal thickness， maintain the integrity of corneal endothelium structure， and promote the recovery of corneal endothelial function； this compound can promote the proliferation of CEC， the mechanism of which may be related to the activation of RhoA-ROCK-BMP pathway.

OBJECTIVE: To investigate the effect of folic acid coated-crosslinked urethane-doped polyester elastomer (fCUPE) nerve conduit in repairing long distance peripheral nerve injury. METHODS: Thirty-six 3-month-old male Sprague Dawley rats weighing 180-220 g were randomly assigned to 3 groups, each consisting of 12 rats: CUPE nerve conduit transplantation group (group A), fCUPE nerve conduit transplantation group (group B), and autologous nerve transplantation group (group C), the contralateral healthy limb of group C served as the control group (group D). A 20-mm-long sciatic nerve defect model was established in rats, and corresponding materials were used to repair the nerve defect according to the group. The sciatic function index (SFI) of groups A-C was calculated using the Bain formula at 1, 2, and 3 months after operation. The nerve conduction velocity (NCV) of the affected side in groups A-D was assessed using neuroelectrophysiological techniques. At 3 months after operation, the regenerated nerve tissue was collected from groups A-C for S-100 immunohistochemical staining and Schwann cell count in groups A and B to compare the level of nerve repair and regeneration in each group. RESULTS: At 3 months after operation, the nerve conduits in all groups partially degraded. There was no significant adhesion between the nerve and the conduit and the surrounding tissues, the conduit was well connected with the distal and proximal nerves, and the nerve-like tissues in the conduit could be observed when the nerve conduit stents were cut off. SFI in group A was significantly higher than that in group C at each time point after operation and was significantly higher than that in group B at 2 and 3 months after operation ( P<0.05). There was no significant difference in SFI between groups B and C at each time point after operation ( P>0.05). NCV in group A was significantly slower than that in the other 3 groups at each time point after operation ( P<0.05). The NCV of groups B and C were slower than that of group D, but the difference was significant only at 1 month after operation ( P<0.05). There was no significant difference between groups B and C at each time point after operation ( P>0.05). Immunohistochemical staining showed that the nerve tissue of group A had an abnormal cavo-like structure, light tissue staining, and many non-Schwann cells. In group B, a large quantity of normal neural structures was observed, the staining was deeper than that in group A, and the distribution of dedifferentiated Schwann cells was obvious. In group C, the nerve bundles were arranged neatly, and the tissue staining was the deepest. The number of Schwann cells in group B was (727.50±57.60) cells/mm ², which was significantly more than that in group A [(298.33±153.12) cells/mm ²] ( t=6.139, P<0.001). CONCLUSION The fCUPE nerve conduit is effective in repairing long-distance sciatic nerve defects and is comparable to autologous nerve grafts. It has the potential to be used as a substitute material for peripheral nerve defect transplantation.

Objective:To compare the knowledge of endoscopic screening of gastrointestinal cancers between digestive healthcare workers and new chatbots (chatGPT and new Bing).Methods:A test with twenty-three questions of endoscopic screening of gastrointestinal cancers was conducted, focusing on the appropriate age of screening, high-risk factors, the follow-up time, and the advantages and risks of digestive endoscopy. Digestive healthcare workers were invited to complete the test through electronic questionnaires. New Bing and chatGPT were used to answer each question for 10 rounds. The primary endpoint was the correct rate of all answers. The answer accuracy between digestive healthcare workers and new chatbots were compared using variance analysis, and the factors that affected the accuracy of the answers in digestive healthcare workers were explored using univariate and multivariable liner regression analysis.Results:The results of the test completed by 76 digestive healthcare workers (21 residents, 28 digestive nurses, and 27 digestive doctors) were analyzed. The accuracies were 36.4%±10.9%, 34.5%±10.2%, 52.2%± 12.6%, 46.3%±9.8% and 67.1%±9.3% in residents, digestive nurses, digestive doctors, chatGPT, and new Bing, respectively, with significant difference ( F=22.6, P<0.001). The accuracy was highest in new Bing ( P<0.001). The accuracy was comparable between chatGPT and digestive doctors (LSD- t=-1.398, P=0.166), and both higher than that of digestive nurses (LSD- t=2.956, P=0.004; LSD- t=5.955, P<0.001) and residents (LSD- t=2.402, P=0.018; LSD- t=4.951, P<0.001). Furthermore, the accuracy was comparable between digestive nurses and residents (LSD- t=-0.574, P=0.567). Compared with new Bing, digestive doctors had lower accuracy in answering questions related to adverse events of screening, follow-up recommendation of intestinal metaplasia, high risk factors and screening methods for colon cancer ( P<0.05), but higher accuracy in answering questions related to endoscopic adverse events and screening methods for esophageal cancer ( P<0.05). Multivariable liner regression analysis showed that being digestive doctors ( β=11.7, t=3.054, P=0.003) and questionnaire response time (≥7.6 min) ( β=7.8, t=2.894, P=0.005) were independent factors for the answer accuracy of digestive healthcare workers. Conclusion:Compared with digestive healthcare workers, New chatbots—new Bing has higher accuracy in answering gastrointestinal cancer screening-related questions, but performs poorly in answering questions such as adverse events of endoscopy and screening methods for esophageal cancer.
