Objective To investigate the effects of serum levels of leptin, IGF-1, BDNF and inflammatory markers in patients with post-stroke depression(PSD). Methods By using Hamilton rating scale for depression (HAMD) ,46 patients with post-stroke depression were recruited and 50 patients without depression as the control group. Two weeks after the onset of stroke, serum levels of leptin, insulin growth factor(IGF-1), hs-CRP, intracellular adhesion molecule (ICAM-1) and brain-derived neurotrophic factors (BDNF) were measured by enzymelinked immunosorbent assay(ELISA). Results The levels of leptin and IGF-1 in patients with PSD were significantly higher than that of the control group (( 57.4 ± 14.32) ng/ml vs (17.53 ± 11.62) ng/ml, P = 0. 002;(120.86 ±28.66) ng/ml vs (66.5 ± 17.51) ng/ml, P=0. 004 respectively). The serum levels of leptin and IGFI were positively correlated with the HAMD score(r=0. 724, P＜0. 01; r=0. 641, P＜0. 01 respectively). There was no significant differences in the levels of hs-CRP((2.3 ±0.42) mg/dl vs (2.2 ± 0.28) mg/dl, P= 0. 767),ICAM-1 (( 182.6 ± 50.27) ng/ml vs (178.7 ± 51.14) ng/ml, P = 0. 812) and BDNF(( 25.8 ± 8.35) ng/ml vs (24.2 ±7.48)ng/ml, P = 0.580)in the two groups. Conclusion The serum levels of leptin and IGF-1 may be associated with post-stroke depression and may be the markers of PSD in the old stroke patients.

Objective To investigate adverse events report intent and its influencing factors in clinical nurses. Methods Questionnaire investigation was conducted among 917 clinical nurses from ten hospitals in Tai'an city using the Intent to Report Questionnaire. Results The score of clinical nurses adverse events report intent was 36.80 ± 19.71. The score of each dimension in descending order were:nurses operation adverse events, system process adverse events, and patient care adverse events. Hospital levels were significant influencing factors of clinical nurses adverse events report intent. Pressure sores were the most frequently reported, and report of patient injury caused by unreasonable nurse manpower allocation was the lowest frequency. Conclusions The level of clinical nurses adverse events report intent need to be improved. Nursing managers should pay attention to improve nurse reporting adverse event in order to better promote the safety of patients and reduce occurrence of adverse event.

Objective To study the effects of community-based rehabilitation on cerebral apoplexy patients with cognitive disorders.Methods 30 cases of cerebral apoplexy patients were enrolled according to relevant standards,who were given standard rehabihtation care in Community Health Service Center(training group) ,while another 30 similar cases from subordinate health service stations (control group) given only rehabilitation guidance once a week.Two groups were not do professional cognitive training.All patients were assessed with Mini Mental State Examination( MMSE), Fugl-Meyer Assessment(FMA) and modified Bathel index rating scale(MBI) to evaluate their cognition ,movement function and activity of daily living(ADL) before training as well as after 4-week and 8-week training.Results There was no signficant difference in cognition,movement functions and ADL between training group and control group before treatment(P>0.05).The differences in the assessment of Brounnstrom scale and MBI between two groups after 4-week training were not significant( P > 0.05 ).The scores of Fugl-Meyer scale, MMSE and Barthel index of the training group after 8-week training were significantly higher than those of control group( all P < 0.05 ).Conclusion Community-based rehabilitation training could improve the movement functions and ADL,and cognitive functions of cerebral apoplexy patients.

Objective To discuss the clinical application value of Omaha system-based targeting nursing care for patients with hepatocellular carcinoma (HCC) who were treated with transcatheter arterial chemoembolization (TACE).Methods A total of 60 advanced HCC patients,who were planned to receive TACE,were prospectively and randomly divided into the control group (n=30) and the observation group (n=30).Routine nursing mode was adopted for the patients in the control group,while Omaha system nursing model was employed for the patients in the observation group.The patients of the observation group were evaluated with Omaha system at the time of admission,the key common problems were screened out and targeted nursing measures were employed.Meanwhile,on the days of admission and discharge all the patients of both groups were asked to fill in the forms of Hamilton depression scale (HAMD-17),Hamilton anxiety scale (HAMA),social support rating scale (SSQ) and numerical pain rating scale (NRS);and the degrees of depression,anxiety,social support and pain were respectively assessed.Results Both nursing modes could improve the degrees of depression and anxiety as well as the social support system of HCC patients,but the curative effect of these two aspects in the observation group were obviously better than those in the control group (P＜0.05).No statistically significant difference in the improvement of pain degree existed between the two nursing models,but Omaha system-based targeting nursing mode could alleviate the patient's pain to a certain extent.Conclusion For patients with advanced HCC,Omaha system-based targeting nursing care can alleviate the patient's negative emotion and promote the patients to establish effective social support system,this nursing mode is superior to conventional nursing mode.Therefore,Omaha system-based targeting nursing has great application potential in clinical practice.

ObjectiveTo investigate the feasibility and efficacy of using the hepatoduodenal ligament tension-reduced operation (tension-reduced operation in short) for iatrogenic bile duct injury where the bile duct was severely defective. MethodsBetween March 2006 and May 2009, the authors treated 6 patients with iatrogenic bile duct injury (Bismuth type Ⅱ : 5 patients and type Ⅲ : 1 patient). A no. 7 black silk thread was used to hold the hilar plate tissues and the seromuscular layer of the bulbous part of the duodenum closer together and knots were tied. This method brought the porta hepatis and the duodenal bulb closer together and the hepatoduodenal ligament was shortened. An end to end anastomosis could then be made between the two broken ends of the defective bile duct without tension. ResultsSix patients suffered from bile duct injury and they recovered fully after the tensionreduced operation. There was no complication on follow-up. ConclusionsThe tension-reduced operation was efficacious in the treatment of iatrogenic bile duct injury. This technique should be popularized and more widely used.

Objective To explore the origin of ovarian high grade serous carcinoma(HGSC) through analysing the expression and significance of PAX8,PAX2,p53 and RAS in the ovary and fallopian tube of different types and grades of serous carcinoma. Methods A total of 44 cases tissue samples of ovarian tumor including 34 malignant ovarian tumor and 10 normal normal tissue (as control group) were collected from the admitted patients in Affiliated Tumor Hospital of Guangxi Medical University from January 2015 to January 2016. Fallopian tube tissues were segmented in accordance with the fimbria, ampulla, isthmus and the corresponding ovarian tissues were by the side. There were 34 cases of patients with ovarian cancer including 29 cases of epithelial ovarian cancer (27 serous carcinoma, 1 mucinous carcinoma,1 endometrioid adenocarcinoma)and 5 non-epithelial ovarian cancer(sex cord-interstitial tumor). Among 27 cases of patients with ovarian serous cancer,there were 23 HGSC and 4 low-grade ovarian serous cancer (LGSC). One hundred fifty-three cases of samples were diagnosed as ovarian serous cancer by Shandong University Affiliated Qilu Hospital from 2005 to 2013 and these samples were made tissue microarray.(1)To analyze the expression and differences of PAX8,PAX2,p53 and RAS in the above tissues and tissue microarray from ovarian and tubal of HGSC and control women by immunohistochemistry methods.(2)To compare the expression levels of PAX8,PAX2,p53 and RAS in ovarian and fallopian tubes of ovarian cancer patients with different pathological types. (3) To analyze the correlations of tubal and ovarian tissue in PAX8,PAX2,p53 and RAS expression of HGSC.(4)To analyze the factors of the prognosis of ovarian serous cancer in tissue microarray by single factor analysis method. Results (1)PAX8,PAX2, p53 and RAS expression was negative in normal ovarian epithelium of control group,but the expression of PAX8, PAX2, p53 and RAS were strongly positive brown in secrete cells of normal fallopian tube epithelium.(2)p53 and RAS expression of fallopian tube epithelium in the epithelial ovarian cancer group were significantly higher than those in the non-epithelial ovarian cancer groups(P<0.05),but the expression of PAX8 and PAX2 in fallopian tube and the expression of PAX8,PAX2,p53 and RAS in ovarian tissue was not statistically significant in the groups(P>0.05).PAX8,PAX2 and p53 expression of the ovarian in HGSC group were significantly higher than those in LGSC group(P<0.05),while the expression of RAS was lower in the ovarian of the high-grade group (P<0.05), while the expression of PAX8, PAX2, p53 and RAS in fallopian tube was not statistically significant in the groups(P>0.05).(3)There was a significantly positive correlation between fallopian tube and the corresponding ovary of HGSC in PAX8 and PAX2 expression(r=0.422, P=0.045; r=0.693, P=0.000), but not correlation in p53 and RAS expression (r=0.058, P=0.793; r=-0.190,P=0.384).(4)Univariate survival analysis showed that the progression free survival time in patients with ovarian serous cancer group was significantly correlated with the protein expression of PAX8, PAX2 and RAS(P<0.05),but there were not correlated with age,surgical staging,cell differentiation,lymph node metastasis and preoperative chemotherapy and p53 protein expression (P>0.05). The total survival time in patients with ovarian serous cancer group was significantly correlated with the protein expression of PAX8 (P<0.05),but there were not correlated with age,surgical staging,cell differentiation,lymph node metastasis and preoperative chemotherapy and the protein expression of PAX2, RAS and p53 (P>0.05). Conclusions PAX8, PAX2, p53, RAS are of great significance for the study of origin of HGSC. HGSC may be derived from fallopian tube, but further investigation would be necessary to confirm this. PAX8, PAX2, p53, RAS could be expected to be used as predictors of survival prognosis in patients with ovarian serous cancer.

Objective To evaluate the skeletal stability of joint orthognathic and orthodontic treatment for cleft patients compared with non-cleft patients.Methods Fifteen cleft patient diagnosed with dental facial deformities underwent joint orthognathic and orthodontic treatment.Cephalometric analysis was carried out at T0 (before treatment),T1 (2 weeks after surgery),T2 (6 months after surgery) and T3 (24 months after surgery).The comparison of maxillary anterior-posterior and superiorinferior movement was performed with non-cleft orthognathic group (n =15) at the same follow-up time point.Results The maxilla was move forward for (3.8 ± 1.5) mm and downward for (2.4± 0.8) mm of cleft group.The relapse distance was (1.2±-0.7) mm (T1-T2:31.6％) in AP direction and (0.9±0.6) mm (T1-T2:37.5％) in vertical direction.At the time of 24 months after operation,the relapse distance was (1.0±0.5) mm (T1-T3:26.0％) in AP direction and (0.8±0.8) mm (T1-T3:33.3％) vertically.In non-cleft group,the maxilla was move (4.3±1.2) mm anteriorly and (2.2± 1.9) mm vertically.The relapse distance was (0.9±1.2) mm (T1-T2:20.9％) anteriorly and (0.8± 0.9) mm (T1-T2:36.6％) vertically at 6 months post-operatively.At 24 months after surgery the relapse distance was (1.1±0.6) mm (T1-T3:25.6％) anteriorly and (0.9±0.5) mm (T1-T3:40.9％) vertically.There were no statistical significant in both 6 months and 24 months follow-up between cleft and non-cleft group (P＞0.05).Conclusions There is no statistic difference of post-surgical relapse rate between cleft and non-cleft orthognathic and orthodontic treatments,although the relapse distances are greater than that in cleft group.

Objective:To investigate the correlation between tooth movement and profile change in patients with class Ⅱ division 1 malocclusion.Methods:Pre- and post-treatment lateral cephalograms of 42 patients [10 males and 32 females, (23.8±6.3) years old, mean treatment time: 1.9 years] with class Ⅱ division 1 malocclusion were collected in Department of Oral & Cranio-Maxillofacial Surgery, Ninth People′s Hospital, Shanghai Jiao Tong University School of Medicine from June 2012 to November 2017. The patients were treated with extraction of four first premolars or two maxillary first premolars. Cephalometric analysis was carried out before and after treatment. Thirty parameters were measured. The changes of soft and hard tissue after orthodontic treatment and their correlations were analyzed using bivariate linear regression. Related factors affecting the upper and lower lip, nasolabial angle (NLA) and mentolabial angle (MLA) were analyzed according to the standardized regression coefficient ( Beta). Results:Among all the 30 parameters, 18 parameters were statistically different before and after treatment. After treatment, upper central incisor sagittal distance [(63.87±7.14) mm] and upper lip sagittal distance [(77.73±7.60) mm] were significantly decreased ( P<0.05). The changes in 14 parameters after treatment showed linear relationship including strong positive correlation between upper lip sagittal retraction and upper central incisor sagittal retraction ( r=0.649, P<0.01). There were moderate positive correlations between upper lip and upper central incisor vertical movement ( r=0.544, P<0.01). While the sagittal change of gnathion and the Y-axis angle showed moderate negative correlations ( r=0.537, P<0.01). The stepwise multiple linear regression showed that the retraction of upper lip process was correlated with the retraction of upper central incisor, the increase of occlusal plane angle and the increase of upper central incisor angle, which was most correlated with the retraction of upper central incisor ( Beta=0.79). The downward displacement of upper lip process was correlated with the downward displacement of upper incisor, the decrease of upper central incisor angle, the decrease of the distance between maxillary first molar and palatal plane, and the increase of occlusal plane angle, which was more correlated with the downward displacement of upper incisor and the increase of occlusal plane angle ( Beta=0.59). The downward displacement of lower lip process was correlated with the downward displacement of upper incisor and lower incisor, which was more correlated with the upper incisor ( Beta=0.36). Conclusions:The relationship among nose, lips and chin was more coordinated. Incisor retraction had significant influence on lip prominence, and the lower lip position was highly related to the movement of upper incisor in sagittal and vertical dimension after orthodontic treatment in patients with class Ⅱ division 1 malocclusion. However, tooth movement had limited impact on the chin position.

Objective:To understand the epidemiology of rubella and the genetic characteristics of the virus circulating during the period 2021-2022, providing basic scientific data for rubella prevention and control in China.Methods:National rubella incidence data for the period 2021-2022 were obtained from the Infectious Disease Surveillance System module and the Surveillance Report Management module of the China′s Disease Prevention and Control Information System. Positive rubella virus(RuV)isolates were obtained from the National Measles/Rubella Laboratory Network. Two nucleotide (nt) fragments [F1-480 (8 633-9 112 nt) and F2-633 (8 945-9 577 nt)] located in the E1 gene were amplified and determined by reverse transcription polymerase chain reaction (RT-PCR), and the target gene (E1-739) was obtained after collating and splicing. The sequences obtained in this study were used to construct a phylogenetic tree with the reported reference strains for genotype and lineage identification. Additionally, the phylogenetic analysis was performed to assess their genetic relatedness of RuV strains prevalent in China during 2018-2020 from GenBank database.Results:In 2021-2022, the rubella incidence in China was 0.06/100, 000 (2021: 840 cases; 2022: 784 cases), with cases primarily concentrated in the western and southern provinces. Age distribution analysis showed that rubella cases in 2021-2022 was mainly in children under 5 years of age (2021: 34.17%, 287/840; 2022: 42.09%, 330/784), with the highest proportion in children aged 0-2 years. Further analysis of the immunization history of cases revealed that in the 8-23 months age group, a significant proportion of cases had received only one dose of rubella containing vaccine (RCV); cases in the 2-14 years age group were mainly among children who had received two or more doses of RCV; however, cases over 15 years of age were primarily found in individuals who had not received RCV or had unknown immunization history. National virological surveillance data showed that totally 22 RuV virus isolates were obtained, from 6 provinces in China during 2021-2022, which belonged to lineage 1E-L2 (11 strains) and 2B-L2c (11 strains). And these viruses displayed high genetic homology with RuV prevalent from 2018 to 2020.Conclusions:The incidence of rubella in China was maintained at a low level during 2021-2022, and the prevalent RuV strains were lineage 1E-L2 and 2B-L2c.

Objective: To observe the changes of extracellular histones and pulmonary microvascular endothelial cells, and study the activating role of extracellular histones to pulmonary microvascular endothelial cells in the pathogenesis of acute respiratory distress syndrome (ARDS) . Methods: The correlation of the severity of acute lung injury with extracellular histones and pulmonary endothelial damage was studied through mice model, and acute lung injury was produced by aspiration of different concentrations of hydrochloric acid (0.01、0.1、0.3 and 0.5 mol/L, 2 ml/kg). Tumor necrosis factor-α (TNF-α), soluble thrombomodulin (sTM) and lung pathological change were measured. The pro-inflammatory role of extracellular histones was tested by injecting calf thymus histones (CTH) or specific anti-H4 antibody through tail vein. The direct activating role of extracellular histones to pulmonary microvascular endothelial cells was studied through pulmonary endothelial model. Results: The extracellular histones in plasma were increased obviously 6h after aspiration of different concentrations of hydrochloric acid in mice. A positive correlation was seen between extracellular histones and concentrations of aspirated hydrochloric acid (r=0.9180, P<0.05). The sTM in plasma also showed a positive correlation with concentrations of aspirated hydrochloric acid (r=0.8701, P<0.05). Merely administering CTH could not only increase TNF-α and sTM in plasma but also cause obvious lung injury, while specific anti-H4 antibody could relieve the inflammation and lung damage caused by CTH. Extracellular histones could directly damage pulmonary endothelial cells to release sTM in pulmonary endothelial model in vitro, while anti-H4 antibody could protect the endothelial cells. Conclusion Extracellular histones are the key endogenic inflammatory mediators during the pathogenesis of ARDS caused by aspiration of hydrochloric acid, which could promote inflammation by directly activating pulmonary endothelial cells.
