ABSTRACT
Objective:To explore the initial motivation of nursing students to engage in voluntary service for the aged, and to provide scientific basis for the formulation of strategies and measures of voluntary service for the aged.Methods:Totally 25 nursing students volunteers who regularly participated in the volunteer service for the aged in Changsha First Welfare Home were selected by objective sampling method for semi-structured in-depth interviews, and the data were analyzed by Colaizzi phenomenological 7-step analysis method.Results:Four themes of nursing students' initial motivation to participate in voluntary service for the aged were extracted: self-interest motivation, altruistic motivation, affinity motivation and achievement motivation. Among them, self-interest motivation included two sub-themes: enriching college life and life experience, improving one's own ability and gaining professional experience; altruistic motivation included two sub-themes: accompanying and helping the elderly and eliminating loneliness of the elderly; affinity motivation included two sub-themes: establishing emotional sustenance and making up for the lack of emotion; achievement motivation included two sub-themes: facing challenges bravely, acquiring a sense of achievement, serving society and others, and realizing one's own value.Conclusion:Nursing students have a clear initial motivation to participate in the voluntary service for the aged of the aged care facilities, and schools can strengthen the relevant education for students to participate in voluntary service in the training of nursing talents. The voluntary service for the aged can formulate corresponding development strategies and incentives according to the initial motivation of nursing students, so that promote the expansion and stability of the voluntary service for the aged team, and promote the development and improvement of voluntary service for the aged.
ABSTRACT
Objective@#To explore the relationship among mobile phone addiction, locus of control and anxiety in college students.@*Methods@#Using Mobile Phone Addiction Index (MPAI), Internality, Powerful Others, and Chance Scale (IPC), Self-Rating Anxiety Scale (SAS), 826 college students were surveyed and the data were analyzed by SPSS17.0 and Amos24.0.@*Results@#73.6% college students had mobile phone dependence. College students being addicted to mobile phone got higher scores on chance(20.17±6.65), powerful others(18.74±7.45) and anxiety(45.95±10.41)than non-cellphone dependent students (chance(17.09±6.67), powerful others(15.03±7.65)and anxiety(40.44±8.29)). There were significant differences(all P<0.01). The scores on mobile phone addiction were positively related to chance, powerful others and anxiety (r=0.289, r=0.261, r=0.267, P<0.01). Anxiety played a partial mediating role between chance and mobile phone addiction and the mediating effect was 26.6%.@*Conclusion@#Chance can directly predict mobile phone addiction or indirectly predict cell phone addiction through anxiety.

According to WHO classification of tumors of haematopoietic and lymphoid tissues(2008)and updated classification(2016),the cases were studied by microscopy,immunohistochemistry and in situ hybridization.Results In 20 cases of tumors of haematopoietic and lymphoid tissue,the mean and median age was 48.5 and 56 years old(range:16-77 years old).In cases of lymphoma-like lesion of uterine cervix,the mean and median age was 45.9 and 48 years old(range:23-62 years old).The patients with neoplasm present as fever,fatigue, hypogastralgia, colporrhagia and mass etc. Eight cases had history of acute myeloid leukemia, and 3 had myeloid leukemia while pregnancy. One case of chronic lymphocytic leukaemia/small lymphocytic lymphoma(CLL/SLL)had history of ovary small cell carcinoma and high grade serous carcinoma resected with chemotherapy.One case of diffuse large B cell lymphoma(DLBCL)had history of renal transplantation. Lactic dehydrogenase(LDH)was elevated in 9 cases(9/18).The cases of lymphoma-like lesion present as contact bleeding in most cases and all located in cervix. Four cases of neoplasm located in vulva, 1 in vagina,4 in cervix, 4 in uterine corpus, 8 in ovary and 2 in placenta.Clinical staging of NHL: 4 case was stageⅠ,1 case of stageⅢ,and 4 cases of stageⅣ.Pathological morphology:9 cases were myeloid sarcoma, 2 cases were placenta invaded by myeloid leukemia. Six cases were DLBCL, and 1 case was CLL/SLL, 1 case was mucosa associated lymphoid tissuse lymphoma(MALToma), and 1 case was anaplastic large cell lymphoma. Resected mass, chemotherapy was performed in tumors of haematopoietic and lymphoid tissue. Five cases of myeloid sarcoma and 2 of NHL died. In 13 cases of lymphoma-like lesion of uterine cervix, the general condition was good as following up. Conclusions The clinical history, pathological morphology and immunohistochemistry are very important for diagnosing tumors of haematopoietic and lymphoid tissue in the female productive tract.Resection with chemotherapy is recommended in treatment. The prognosis of lymphoma-like lesion of uterine cervix is good,and should be differentiated from lymphoma.
ABSTRACT
Objective To investigate the clinical efficacy ofYinxing-Tongzhi dripping pills combined with clopidogrel in the secondary prevention of non cardiac acute cerebral infarction (ACI).Methods A total of 117 patients met the inclusion criteria in our hospital were divided into the control group (58 cases) and observation group (59 cases). The control group was orally clopidogrel 75 mg/d in prevention of ACI recurrence, and the observation group addedYinxing-Tongzhi dripping pills based on the treatment of control group, each time 50 mg tid. Both groups were fellowed-up 1 year. The color Doppler ultrasound was used for determination of carotid artery interior and medial thickness (IMT), maximum thickness of the common carotid artery, internal carotid artery, external carotid artery plaques for evaluation. The carotid plaque score was introduced into evaluation of crouse plaque; blood rheometer was used for testing of whole blood viscosity (BV) and plasma viscosity (PV); automatic biochemical analyzer was used for testinghigh sensitive protein (hs-CRP), D-dimer and homocysteine (HCY). The patient's infertility response was recorded during the medication,and adverse drug reactions of the two groups were compared.Results The reductions on IMT (0.18 ± 0.07vs. 0.12 ± 0.04,t=5.679)mm and carotid plaque score (1.25 ± 0.31vs. 1.04 ± 0.26,t=5.009) of the observation group after follow-up were significantly higher than the control group (P<0.05). The reductions on low shear BV (0.73 ± 0.19vs. 0.51 ± 0.16,t=6.769) mPa?s and PV (0.37 ± 0.09vs. 0.22 ± 0.05,t=11.117) mPa?s of the observation group after follow-up were significantly higher than the control group (P<0.05). The reductons on hs-CRP (3.67 ± 0.88vs. 2.65 ± 0.75,t=6.742) mg/L, D-dimer (107.6 ± 23.8vs. 89.3 ± 18.7,t=4.629) g/L、Hcy (15.1 ± 2.9vs. 11.7 ± 2.6,t=6.679) mol/L of the observation group were significantly higher than the control group (P<0.05). The observation group with incidences of transient ischemic attack (8.5%vs. 19.0%), ACI recurrence (0vs. 8.6%), cerebrovascular death (0vs. 1.7%) were significantly lowerer than the control group. The ACI recurrences of the two groups with statistically significant difference (P=0.027).Conclusions Based on orally clopidogrel in secondary prevention of ACI,Yinxing-Tongzhi dripping pills combined can reduce blood viscosity, inhibit atherosclerotic plaque growth, reduce ACI recurrence, and with no increase of adverse reactions.

ABSTRACT
Bipolar disorder (BD), characterized by recurrent mood swings between depression and mania, is a highly heritable and devastating mental illness with poorly defined pathophysiology. Recent genome-wide molecular genetic studies have identified several protein-coding genes and microRNAs (miRNAs) significantly associated with BD. Notably, some of the proteins expressed from BD-associated genes function in neuronal synapses, suggesting that abnormalities in synaptic function could be one of the key pathogenic mechanisms of BD. In contrast, however, the role of BD-associated miRNAs in disease pathogenesis remains largely unknown, mainly because of a lack of understanding about their target mRNAs and pathways in neurons. To address this problem, in this study, we focused on a recently identified BD-associated but uncharacterized miRNA, miR-1908-5p. We identified and validated its novel target genes including DLGAP4, GRIN1, STX1A, CLSTN1 and GRM4, which all function in neuronal glutamatergic synapses. Moreover, bioinformatic analyses of human brain expression profiles revealed that the expression levels of miR-1908-5p and its synaptic target genes show an inverse-correlation in many brain regions. In our preliminary experiments, the expression of miR-1908-5p was increased after chronic treatment with valproate but not lithium in control human neural progenitor cells. In contrast, it was decreased by valproate in neural progenitor cells derived from dermal fibroblasts of a BD subject. Together, our results provide new insights into the potential role of miR-1908-5p in the pathogenesis of BD and also propose a hypothesis that neuronal synapses could be a key converging pathway of some BD-associated protein-coding genes and miRNAs.

ABSTRACT
Objective To study the relationships between androgen receptor (AR)expression and the clinicopathological features and prognosis of young patients (age≤35 years)with early-onset breast cancer in Xinjiang.Methods One hundred and forty-five young patients (age≤35 years)with invasive breast cancer who underwent surgery in Affiliated Cancer Hospital of of Xinjiang Medical University from January 201 0 to December 201 2 were collected.The expressions of AR in 1 45 patiens with early-onset breast cancer were detec-ted by immunohistochemical method.The relationships between AR expression and the clinicopathological fea-tures and prognosis of patients with early-onset breast cancer were retrospective analysed.Results The posi-tive rate of AR expression of patients with early-onset breast cancer in Xinjiang was 69.0% (1 00 /1 45).Single factor analysis showed that AR expression was related with neurovascular invasion (χ2 =5.309,P =0.021 ) and lymph node metastasis (χ2 =6.073,P =0.01 4),but it was not related with ethnicity (χ2 =0.097,P =0.755),age (χ2 =0.045,P =0.831 ),feeding history (χ2 =0.066,P =0.797),family history of cancer (P =0.556),histological grade (P =0.469),tumor size (χ2 =1 .006,P =0.605)and clinical stage (χ2 =4.381 ,P =0.223).The median follow-up time was 47 months.There was no significant difference between AR expression and disease-free survival of patients with early-onset breast cancer (χ2 =1 .972,P =0.1 60). Conclusion Early-onset breast cancer patients with AR positive are more likely to appear lymph node metasta-sis and neurovascular invasion than the patients with AR negative,which has certain guidance means for the treatment of early-onset breast cancer with lymph node metastasis positive.
ABSTRACT
Background and purpose:The incidence of esophageal cancer of Kazakh race is higher than that of Han people. EphA2, as a member of Eph protein family, is related to a variety of malignant tumors. This study used immunohistochemical method and enzyme-linked immunoassay to detect EphA2 in tissues and serums of Kazakh and Han patients. Therefore to analyze the expression differences of EphA2 in esophageal squamous cell carcinoma (ESCC) tissues and serum of Kazakh and Han patients in Xinjiang, and the relationship with pathological features. Methods:The expression of EphA2 protein was detected by immunohistochemistry method in 100 cases of ESCC tissues and adjacent normal esophageal tissues;Then was tested by ELISA in those cases’ serum and 60 healthy persons. Results:The positive expression rate of EphA2 protein in ESCC and corresponding adjacent tissues were 72.0%, 28.0% in Kazakh, and 62.0%, 26.0% in Han people, respectively, and the differences were statistically significant (P=0.000) in the 2 nations. EphA2 protein levels in serum of ESCC and healthy persons, and Kazakh were (58.36±12.60) and (29.39±7.34) pg/mL, Han Chinese were (58.79±13.29) and (29.39±7.34) pg/mL respectively, there were statistical signiifcance (P=0.000). In ESCC of Kazakh and Han people, EphA2 protein expression had relationship with lymph node metastasis, TNM stage and tumor depth of invasion (P0.05). Conclusion:The high expression of EphA2 protein may contribute to the occurrence, invasion and metastasis of Kazakh and Han ESCC patients. EphA2 protein expression in tissues and serum of patients with ESCC may be related to the primary tumor invasion, lymph node metastasis and TNM stage. The expression of EphA2 protein in peripheral blood of patients with esophageal cancer in Kazakh may be related to depth the of invasion.
ABSTRACT
Objective To estimate the effect of pedicle screw fixation of thoracolumbar fractures via paraspinal approach and compare it with the conventional posterior midline approach.Methods Forty-two cases of thoracolumbar monosegmental fractures subjected to single posterior pedicle screw fixation and reduction from December 2008 to May 2010 were included in the study.Among the patients,19 cases were operated through paraspinal muscular-sparing approach (paraspinal approach group) and 23 cases through posterior midline surgical approach (conventional approach group).Surgical incision length,operation time,intraoperative blood loss,postoperative drainage volume,postoperative hospital stay,pre-and post-operative VAS and other perioperative indices as well as fracture reduction outcome were compared between the two groups.Oswestry disability index (ODI) was assessed after operation.Results There were no statistical differences between the two groups in aspects of surgical incision length,operation time,postoperative hospital stay,height restoration of fractured vertebra (P ＞ 0.05),but intraoperative blood loss (148.5 ± 26.5) ml,postoperative draining loss (72.9 ± 17.3) ml,postoperative VAS (1.1 ± 0.3) points and ODI (13.4 ± 2.7) points in paraspinal approach group showed statistical differences from those in conventional approach group (P ＜ 0.05).Conclusion Paraspinal muscle-sparing approach is characterized by minor trauma,less bleeding,slight pain and quick recovery as compared with conventional posterior midline approach and hence may be the preferred choice for the treatment of thoracolumbar fracture without spinal canal decompression.

ABSTRACT
Objective To investigate the effectiveness of simple peritoneal lavage combined with venous-venous hemofiltration therapy for severe acute pancreatitis (SAP). Methods Needles were inserted into abdominal cavity and tee was connected, then normal saline was administrated and discharged, followed by lidocaine, dexamethasone and antibiotics once daily until bloody peritoneal drainage became clear. At the same time venous-venous hemofiltration was used. Results 61 SAP patients were randomly divided into peritoneal lavage + hemofiltration group (treatment group, n =31) and control group (n = 31). The time to abdominal pain relief, abdominal distention relief, nausea and vomiting disappearance, peritoneal irritation disappearance was (1.5 ±0.3)d,(2.7 ±0.3)d, (1.9 ±0.3)d, (1.5 ±0.2)d, and the time to cure was (11.0 ±2.0)d in the treatment group, which was significantly shorter than that in the control group [(3.9 ± 0. 3) d, (4.5 ±0.6)d, (3.7 ±0.2)d, (5.3 ±0.4)d, (18.0 ±2.5)d, P＜0.05]. At the 1st day of treatment, serum ALT,AST was significantly lower than that in the control group; at the 3rd day of treatment, the serum and urine amylase and serum levels of TNF-α, IL-6 and IL-8 level were significantly lower, but the serum level of IL-10,HCO3-was significantly higher than that in the control group (P ＜ 0.05 or ＜ 0. 01); at the 5th day of treatment, the serum Bun and Cr level were significantly lower than those in the control group (P ＜ 0. 05).Conclusions Simple peritoneal lavage combined with venous-venous hemofiltration therapy can effectively eliminate the inflammatory factors, which is more rational and effective for the treatment of severe acute pancreatitis.
ABSTRACT
Objective To study changes of endothelin (ET),nitric oxide (NO) in plasma and treatment effect of puerarin on acute pancreatitis (AP). Methods Seventy-three patients with AP were randomly divided into 2 groups: puerarin group (38 cases, puerarin plus basic treatment) and non puerarin group (35 cases, basic treatment ). ET was measured by radioimmunoassay, NO was measured by nitrate reductase and plasma amylase and uric amylase were determined by Somogyi before and after the treatment.Twenty healthy persons were recruited as control group. Results The levels of ET[(40.6±15.8) ng/L]and NO[(62.3±27.6) mmol/L] decreased after treatment in puerarin group, which were significantly lower than those in non puerarin group[(82.3±20.6) ng/L, (92.6±24.8 ) mmol/L]( P < 0.05 ). Compared with those in non puerarin group[(1182.0±520.0), (5623.0±1326.0) U/L and (5.12±0.76)d], plasma amylase and uric amylase [(802.0±170.0), (4102.0±1126.0) U/L], the time of abdominal pain relief [(2.20±0.72) d] was lower in puerarin group (P<0.05). Conclusions The plasma ET and NO might play a key role in the development of AP. Therapeutic effect of puerarin is sure in AP.
ABSTRACT
Objective To investigate the clinical effect and pathogenesis of tiopronin in treating acute pancreatitis complicated with liver damages. Methods Eighty-one patients with acute pancreatitis complicated with liver damages were randomly divided into two groups. The control group (40 cases) received routine treatment, and the treatment group (41 cases ) received routine treatment and tiopronin. The liver function, pancreatic enzyme indexes and C-reactive protein (CRP), the length of hospital stay was recorded. Results After 8 days' treatment, the liver function improved, and the levels of pancreatic enzyme indexes and CRP were decreased significanfly in both groups, and these changes were more obvious in treatment group (P <0.05). The length of hospital stay of mild acute pancreatitis in treatment group was significantly shorter than that in control group [ (8.6 ± 2.7 ) d vs. ( 13.8 ± 3.5 ) d ] (P < 0.05 ). Conclusions Tiopronin has beneficial effects in treating acute pancreatitis complicated with liver damages,and it has a therapeutic effect in acute pancreatitis at the same time. The mechanism may be related with the inhibition of inflammatory mediators, oxygen free radicals scavenging and other effects.

Objective Develop a reversed-phase high performance liquid chromatography (HPLC) methodfor detecting isoniazid in vitreous humor and spinal fluid.Method Vanillin, as a derivative reagent, was added to the vitreous humor and spinal fluid samples. Isoniazid and vanillin reacted to form isonicotinoyl hydrazone which was separated and detected. The pretreatment method of sample, the linear range, the precision, the recovery of isoniazid were all established by using rabbit's vitreous humor and spinal fluid spiked with standard isoniazid. The HPLC method has then been applied to investigate the concentration of isoniazid in intoxicated rabbits'vitreous numor and spinal fluid respectively.Results As established in the method, the linear range was 0.2?g/ml～12.0?g/ml (for vitreous humor ?=0.9990, for spinal fluid ?=0.9988). The detective limit was 0.2?g/ml. The intra and inter-day precision of assay for isoniazid were less than 4.9%( n =5) in vitreous numor and spinal fluid. The average recoveries of isoniazid were more than 97.1%. The concentration of isoniazid was 74.60?7.40?g/ml in vitreous humor, 88.95?10.12?g /ml in spinal fluid.Conclusion The HPLC method is suitable for analyzing isoniazid in the vitreous numor and spinal fluid.
