Objective To investigate the effect of emergency nursing pathway in emergency treatment of patients with questionable sources. Methods A clinical nursing pathway for the treatment for patients with questionable sources was formulated. From February to December 2014, 78 patients with questionable sources treated by clinical nursing pathway were selected as the observation group. From January to November 2013, 75 patients with questionable sources treated by routine nursing care methods were selected as the control group. Differences were compared in duration of staying in the emergency department, nursing complication and fees paid rate between the two groups. Results For the average duration of staying in the emergency department, the observation group was lower than that in the control group [19.35%(9.08) vs. 19.90%(25.20), P< 0.05)]. For the nursing complication rate, the observation group was significantly lower than that of the control group [1.28%(1/78) vs.10.67%(8/75), P<0.05]. For the fees paid rate, the observation group was significantly higher than that in the control group [64.10%(50/78) vs. 33.33%(25/75), P<0.01]. Conclusions By the emergency nursing pathway, emergent patients with questionable sources will be treated with satisfactory result in the shortest time.

Objective To investigate the distribution of androgen receptor (AR) gene CAGrepeats in the Chinese Han nationality and its application in genetic diagnosis for Kennedy's disease (KD). MethodsRT-PCR,denaturing polyacrylamide gel electrophoresis (DPAGE) and gene sequencing were conducted for AR gene CAG repetition among 100 healthy controls and 28 patients diagnosed as motorneuron diseases,and the number of the repetition was counted. Results The healthy controls had a range of 15-31 times of CAG repetition,with an average of (23 ± 3) times.Among patients with motoneuron disease,3 cases with CAG repetition for more than 40 times (namely,46,47 and 47 times) were diagnosed as KD.The main clinical manifestations included slow progress of limb weakness,primarily in the proximal lower limbs,fatigue accompanied by myalgia,muscle jumping,muscle atrophy,elevated serum creatine kinase (CK) levels,neurogenic damage revealed by electromyogram (EMG) and androgen insensitivity.Conclusions The incidence of KDmay be underestimated in the Chinese population.Performing genetic diagnosis in patients with motor neuron disease for AR gene can improve clinical diagnosis and avoid misdiagnosis.

Total HCV-cAg was positive in 71 (35.3%) of 201 samples . There was no significant difference between the detection rate of HCV RNA by PCR and total HCV-cAg by ELISA. Conclusion Detection of total core antigen of HCV is suitable to be used as to diagnose HCV in clinic.

Objective To investigate the level of vitamin D in patients with membranous nephropathy and its correlation with proteinuria. Methods Eighty patients with membranous nephropathy were selected from May 2012 to May 2017 in the Department of Nephrology,Shijiazhuang First Hospital. They were divided into two groups with 40 cases in each group. The control group was given prednisolone acetate orally,while the study group was given prednisolone acetate and active vitamin D orally. All patients were followed up for 1 year. Blood urea nitrogen ( BUN), serum creatinine ( Scr), C-reactive protein ( CRP ), cholesterol (TC),triglyceride (TG),calcium (Ca),phosphorus (P),parathyroid hormone (PTH),urinary protein,1,25-dihydroxyvitamin D3 ( 1, 25 ( OH) 2D3) and transforming growth factor-beta ( TG) were measured monthly. F-beta 1 ) and other related biochemical indicators were recorded. Results Before treatment,the level of 1,25(OH) 2D3 in the control group was (3. 67+3. 67) μg／L,while that in the study group was (3. 69+3. 70) μg／L. There was no significant difference ( t＝1. 259,P＞0. 05) . One year after treatment,the level of 1,25(OH) 2D3 in the control group was (4. 87+2. 92) μg／L,while that in the study group was (19. 58+12. 12) μg／L,which was significantly higher in the study group than in the control group (t＝12. 384,P＜0. 05). Serum 1,25 (OH) 2D3 levels were positively correlated with blood calcium,plasma albumin,podocyte and TGF-β1 (r＝0. 301,0. 387,0. 342 and 0. 181,respectively,P＜0. 05); serum 1,25 ( OH) 2D3 levels were negatively correlated with blood phosphorus content,total cholesterol and 24 h urinary protein quantity (r value was －0. 265,－0. 033 and －0. 265,respectively,P＜0. 05) . Serum albumin was an independent factor of serum 1, 25 ( OH ) 2D3 ( P＜0. 05 ) . Conclusion The serum albumin is an independent risk factor for 1, 25 ( OH ) 2D3 in patients with membranous nephropathy. Vitamin D is negatively correlated with proteinuria. Active vitamin D has a better effect on proteinuria in patients with membranous nephropathy.

Objectives: To investigate the expression of phosphoserine aminotransferase 1 (PSAT1) in pancreatic cancer tissues, and its potential role in pancreatic cancer. Methods: The expression of PSAT1 in 98 human pancreatic cancer tissues, which were collected from the People＇s Hospital of Guizhou, between July 2013 to July 2017, and the corresponding adjacent normal tissues was analyzed by immunohistochemical staining. Additionally, the relationship between the expression of PSAT1 and the clinicopathological parame-ters, overall survival (OS), and disease-free survival (DFS) of patients with pancreatic cancer was evaluated. The human pancreatic can-cer cell lines, BxPC-3 and SW1990, were transfected with PSAT1-siRNA, to investigate the effect of PSAT1 knockdown on cell prolifera-tion, migration, and invasion. Additionally, we performed Western blot to assess the expression of PI3K/Akt/mTOR-related proteins in PSAT1-knockdown cells. Results: The percentages of PSAT1-positive cells in pancreatic cancer and adjacent non-tumor tissues were 69.4% (68/98) and 5.0% (5/98), respectively, indicating a significantly higher expression of PSAT1 in pancreatic cancer tissues com-pared to adjacent non-tumor tissues (P<0.05). The increased expression of PSAT1 in pancreatic cancer tissues correlated with lymph node metastasis and TNM stage. Kaplan-Meier analysis suggested that a high expression of PSAT1 correlated with a poor OS and DFS compared to a low expression of PSAT1 (P<0.05). Cox regression analysis showed that the expression of PSAT1 is an independent prog-nostic marker for OS and DFS in pancreatic cancer patients (P<0.05, all). Transient transfection of BxPC-3 and SW1990 cells with PSAT1-siRNA markedly reduced the cell proliferation, migration, and invasion abilities of these cells compared to transfection with NC-siRNA (P<0.05). Knockdown of PSAT1 in pancreatic cancer cells also inhibited the expression of p-Akt and p-mTOR (P<0.05). Conclusions: The expression of PSAT1 increases in human pancreatic cancer tissues and cell lines. Additionally, PSAT1 regulates cell proliferation and in-vasion through the PI3K/Akt/mTOR pathway.

Objective To evaluate the effect of an emollient containing Prinsepia utilis Royle oil extracts and other extracts on clinical symptoms and disease recurrence in children aged 2-12 years with atopic dermatitis (AD) in the remission period.Methods A multicenter,randomized,parallel-group,controlled clinical trial was conducted from December 2017 to September 2018.A total of 297 children aged 2-12 years with moderate AD were enrolled from 5 hospitals in China,and randomly divided into the test group (148 cases) and control group (149 cases).In the acute stage,the two groups were both topically treated with mometasone furoate cream once a day on the skin lesions,and with an emollient containing Prinsepia utilis Royle oil extracts and other extracts twice a day throughout the whole body for 2-4 weeks.The children would be enrolled into the remission stage if their Investigator's Global Assessment (IGA) score was ≤ 1 at following visits.In the remission stage,the test group was only topically treated with the emollient twice a day throughout the whole body,while mometasone furoate cream and the emollient were both withdrawn in the control group.At weeks 4,8 and 12 in the remission stage,the recurrence of AD,eczema area and severity index (EASI),children's dermatology life quality index (CDQOL) and adverse events were evaluated.Statistical analysis was carried out with SAS 9.4 software by using t test for comparison of normally distributed continuous data between two groups,chi-square test for comparison of unordered categorical data,Kaplan-Meier method for analysis of survival rates,Cox regression analysis for evaluating the effect of different therapies on AD recurrence in children in the remission stage,and Logistic regression analysis for analysis of odds ratio (OR) of EASI or CDQOL at week 4 in the remission stage between the test group and control group.Results Of the 297 children with AD,31 breached the clinical trial protocol,and 266 were included in the per protocol set (PPS),including 132 in the test group and 134 in the control group.In the PPS,114 and 106 patients completed the follow-up in the test group and control group respectively,and the recurrence rate was significantly lower in the test group (47,41.23％) than in the control group (84,79.25％;x2 =32.96,P ＜ 0.001).The time to recurrence was significantly longer in the test group(61.99 d ± 2.80 d)than in the control group(39.17 d ± 2.54 d,t =6.03,P ＜ 0.001),and the recurrence risk was significantly lower in the test group than in the control group (Log rank test,x2 =32.02,P ＜ 0.001).After adjustment for age and gender,Cox regression analysis showed that the recurrence risk in the test group was 0.35 times that in the control group (HR =0.35,95％ CI:0.24-0.51,P ＜ 0.01).At week 4 in the remission stage,the EASI score at P50-P75 and P75-P100 in the test group were 0.42,0.25 times that in the control group respectively (95％ CI:0.20-0.86,0.12-0.54 respectively;P =0.02,＜ 0.01respectively).Moreover,the CDQOL score at P75-P100 in the test group was 0.33 times that in the control group (95％ CI:0.17-0.65,P ＜ 0.01).No significant difference in the incidence of adverse events was observed between the two groups (P ＞ 0.05).Conclusion Maintenance treatment with the emollient containing Prinsepia utilis Royle oil extracts and other extracts can markedly reduce the recurrence risk in AD children,improve clinical symptoms,and enhance the quality of life.

Objective:To evaluate the risk factors of acute kidney injury (AKI) in patients with multiple wasp stings.Methods:Patients with multiple wasp stings were retrospectively enrolled in Hanzhong Central Hospital from September 2010 to November 2020. Based on whether the patients developed AKI, the patients were divided into AKI group and non-AKI group. The general characteristics and laboratory examinations between the two groups were compared. The logistic regression model was used to analyze the risk factors of AKI.Results:A total of 356 patients with multiple wasp stings were recruited in this study, with 196 males (55.1%). The age was 56.0(45.0, 64.0) years old. There were 59 patients (16.6%) with hypertension and 13 patients (3.6%) with diabetes. There were 51 patients (14.3%) in the AKI group and 305 patients (85.7%) in the non-AKI group. Baseline data and biochemical examinations indicated that the two groups showed significant differences in gender, age, sting sites (systemic or local), sting needles, proportions of gross hematuria, leukocyte count, hemoglobin, creatine kinase, alanine transaminase, aspartate aminotransferase, total bilirubin, proportions of urinary protein, and proportions of urine occult blood (all P<0.05). The multivariate logistic regression analysis results showed that the increasing number of sting needles (every 10 needles increase, OR=1.866, 95% CI 1.289-2.071, P=0.001), gross hematuria ( OR=9.770, 95% CI 2.586-36.910, P=0.001), decreasing hemoglobin (every 1 g/L increase, OR=0.016, 95% CI 0.001-0.355, P=0.009), increasing aspartate aminotransferase (every 100 U/L increase, OR=1.311, 95% CI 1.144-1.502, P<0.001), and increasing total bilirubin (every 10 μmol/L increase, OR=1.200, 95% CI 1.008-1.430, P=0.041) were independent influencing factors of AKI. Conclusions:The increasing number of sting needles, gross hematuria, decreasing hemoglobin, increasing aspartate aminotransferase, and increasing total bilirubin are independent risk factors of AKI in patients with multiple wasp stings.

OBJECTIVE：To compare the an ti-hepatocarcinoma effects of curcumin （CUR）and its derivative hydrazincurcumin （HZC），and to explore the mechanism. METHODS ：MTT assay was used to detect the effects of CUR or HZC （2.5，5，10，20， 40，80 μmol/L）on the proliferation of HepG 2 cells. Flow cytometry was used to detect the effects of CUR or HZC （10，20，40 μmol/L）on cell cycle distribution and apoptosis of HepG 2 cells. Western blotting assay was used to detect the effects of CUR or HZC（10，20，40 μmol/L）on the expression of apoptosis-related protein in HepG 2 cells. The male SD rats were randomly divided into normal control group （n＝10），CUR control group （n＝10），HZC control group （n＝10），model group （n＝30），CUR protection group （n＝30）and HZC protection group （n＝30）. CUR control group and HZC control group were given CUR 85917439。E-mail：zhaoji-an-88@163.com or HZC （80 mg/kg） intraperitoneally. Model group ，CUR protection group and HZC protection group were given diethylnitrosamine （50 mg/kg）intraperitoneally to establish hepatocarcinoma model ；at the same time ，2 protection groups were given CUR or HZC （80 mg/kg）intraperitoneally，twice a day，for consecutive 12 weeks. During medication ，the change of body weight and death of rats were recorded. Twenty four weeks later，liver index of rats was calculated and appearance was observed ；the number of cancer nodules was counted ；HE staining was used to observe the pathological changes of liver tissue and calculate the nuclear division index of hepatocarcinoma ；the proliferating cell nuclear antigen （PCNA）index was detected by immunohistochemistry. RESULTS ：CUR and HZC could increase the inhibitory rate of HepG 2 cells（P＜0.05），and increased the percentage at G 0/G1 phase and apoptotic rate of HepG 2 cells（P＜ 0.05）. CUR and HZC could significantly decrease the protein expression of p-JAK 2，p-STAT3，Bcl-2 and Bcl-xl ，while increased the protein expression of Bax ，Cyt-c，Caspase-9，Caspase-3 and PAPR （P＜0.05）. Above effects of HZC were significantly better than those of CUR （P＜0.05）. The results of animal experiment showed that there was no death ，no liver canceration and no pathological changes in liver appearance and tissue section of the three control groups ；there was no statistical significance in body weight and its increased weight ，liver index ，nuclear division index of carcinoma or PCNA index （P＞0.05）. Compared with model group， survival rate of rats were increased significantly in CUR protection group and HZC protection group ， while hepatocarcinoma incidence and the number of cancer nodules were decreased significantly （P＜0.05）；body weight and its increased weight were increased significantly ，while liver index ，nuclear division index of carcinoma and PCNA index were decreased significantly （P＜0.05）. There were some pathological changes in liver appearance and tissue section ；cancerous lesions with focal necrosis or cancerous lesions with patchy necrosis were observed. There was no statistical significance in the improvement of above indexes in 2 protection groups （P＞0.05）. CONCLUSIONS ：HZC could inhibit the proliferation and induce apoptosis of HepG 2 cells by inhibiting JAK 2/STAT3 signaling pathway and regulating the activation of mitochondrial endogenous pathway，which shows stronger anti-hepatocarcinoma effect in vitro than CUR. On the other hand ，there was no significant difference in the improvement of liver caner indexes in hepatic cancer model rats between HZC and CUR.

Objective: To investigate the current status of professional identity among the undergraduates majoring in public affairs management and the related influence factors. Methods: A stratified cluster sampling method was used to conduct a questionnaire survey among the 115 undergraduates majoring in public affairs management in a medical university in Harbin, China, and the contents of the questionnaires included general status and professional identity. The t-test, one-way analysis of variance, and multiple linear regression analysis were used to analyze the influencing factors of professional identity. In-depth interviews were conducted for some students to explore the profound influencing factors for professional identity among the students majoring in public affairs management. Results: The overall level of professional identity was low among the undergraduates majoring in public affairs management in the medical university in Harbin, and the score of professional identity was 3.25±0.56. The scores of cognitive dimension, emotional dimension, behavioral dimension, and applicable dimension were 3.41±0.69, 3.21±0.78, 3.24±0.71, and 3.13±0.72, respectively. The multivariate analysis showed that grade, academic performance, major selection, and children number in family had significant influence on their professional identity. The students who were at grade four, who had high academic record (b=-0.276, P<0.01), who chose this major independently (b=-0.277, P<0.01), and who were the only child (b=-0.233, P<0.05) had a high score of professional identity. As for the undergraduates at different grades, the undergraduates at grades two and three had a significantly lower score of professional identity than those at grade four (b=-0.296 and -0.369, P<0.05), while there was no significant difference between the undergraduates at grades one and four (b=-0.008, P>0.05). Furthermore, the students with a high score of professional identity had higher possibility to pursue the job related to this major than those with a low score (3.39±0.53 vs. 2.92±0.49, t=4.414, P<0.01). Conclusion Universities should strengthen the publicity of the major of public affairs management, optimize the curriculum, and add job experience, so as to enhance professional identity among students with this major and provide talent for the field of public health management.
