Objective To study the effect of three-dimensional (3D) animation on preoperative anxiety in patients with lumbar disc herniation (LDH). Methods One hundred and eighty-four LDH patients were randomly divided into experiment and control group in equal number. The control group was educated in traditional method and the experiment group in the form of 3D animation. The self-rating anxiety scale (SAS) was used for the assessment 2 h after admission into the hospital and 1d before operation. Results After the intervention, the score by SAS in the observation group was significantly lower than that before the intervention and control groups (P<0.001). The score by SAS in the control group was significantly lower than that of the control group and that before intervention (P<0.001). Conclusion Health education by 3D animation can relieve preoperative anxiety in the patients with lumbar disc herniation.

Objective To explore the relationship between the change in waist circumference (WC) and new onset diabetes (NOD) in a population of north China.Methods A total of 101510 subjects took part in the health examination from 2006 to 2007 for the employees of Kailuan Group.89364 subjects with fasting plasma glucose (FPG) ＜7.0 mmol/L,no history of diabetes,with complete data of FPG and WC,and without taking hypoglycemic agents were sclected as the observation cohort.Subjects who did not participate in the health examination from 2010 to 2011 and had incomplete data were finally excluded and thus 58426 subjects were included for final analysis.According to the baseline WC measurement and its quartile in the health examination during 2006 to 2007,the observed population was divided into two groups (obese group and non-obese group) or four groups ( first,second,third,and forth quartile groups).Multiple logistic regression analysis was used to test the relation between the change in WC and NOD.Results ( 1 ) The incidence of NOD in obese group was higher than that in non-obese group (8.02％ vs 3.37％,P＜0.01 ).Along with increasing WC in the 4 quartile groups,the incidence of NOD was progressively increased,being 2.32％,3.62％,5.46％,and 8.89％ respectively in the total population ( 2.84％,3.65％,5.32％,and 8.95％ in male,and 1.50％,3.41％,6.22％,and 8.51％ in female).( 2 ) Multiple logistic regression analysis showed that compared with the first quartile group,the second,third,and forth quartile groups had increased risks of NOD after adjusting age,gender,and other risk factors,the OR value being 1.17,1.47,and 1.95,respectively.After adjusting above factors in different genders,the influence of the second group on NOD in males and females was not significant,however,they still increased the risks of NOD,with the OR value being 1.08,1.36,and 1.90 in male,and 1.35,1.70,and 1.88 in female,respectively.Conclusion The incidence of NOD is increased with increasing WC.

Objective To observe expression levels of N-methyl-D-aspartate (NMDA) receptor and cholecystokinin (CCK) in the hippocampus and spinal cord in morphine withdrawal or tolerance mice treated by electroacupuncture or catgut embedding and explore the difference between the regulating effects of electroacupuncture and catgut embedding on morphine withdrawal and tolerance.Methods Fifty-six male C57BL/6J mice were randomly allocated to withdrawal control, withdrawal model, withdrawal catgut embedding and withdrawal electroacupuncture groups, and tolerance control, tolerance model, tolerance catgut embedding and tolerance electroacupuncture groups, 7 mice in each group. A model of morphine withdrawal was made by subcutaneous injection of morphine hydrochloride using 7-day increasing addiction method. The withdrawal control group was injected with an equal volume of normal saline at the same time points. In the withdrawal electroacupuncture group, electroacupuncture at bilateral points Shenshu was performed using a Han’s acupoint nerve stimulation device (HANS-200) at 15 min after an injection of morphine hydrochloride. In the withdrawal catgut embedding group, 0.5 cm chromic catgut was embedded in bilateral points Shenshu at 15 min after an injection of morphine hydrochloride. Addiction was promoted by intraperitoneal injection of naloxone 4 mg/kg at 10 o’clock on the seventh day’s morning and Withdrawal reactions were observed in the mice. The score was recorded using the Ryuta Tomoji opioid withdrawal symptoms evaluation scale. NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by enzyme-linked immunosorbent assay (ELISA). A model of morphine tolerance was made by subcutaneous injection of morphine 10 mg/kg. The tolerance control group was injected with tolerance normal saline 10 ml/kg at the same time. In the tolerance catgut embedding group, catgut was embedded in point Shenshu at the first day after model making. In the tolerance electroacupuncture group, point Shenshu was given electroacupuncture at the first day after model making. After seven days of treatment, NMDA receptor and CCK contents in the hippocampus and spinal cord were measured by ELISA.Results There were statistically significant differences in hippocampal NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There was a statistically significant difference in hippocampal NR2B expression between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the withdrawal catgut embedding or withdrawal electroacupuncture group and the withdrawal model group (P<0.05). There were statistically significant differences in spinal cord NR2A, NR2B and CCK expressions between the withdrawal model and withdrawal control groups (P<0.05). There were statistically significant differences in spinal cord NR2A and NR2B expressions between the withdrawal electroacupuncture and withdrawal model groups (P<0.05). There were statistically significant differences in hippocampal NR2A, NR2B and CCK expressions between the tolerance model and tolerance control groups (P<0.05). There was a statistically significant difference in hippocampal CCK expression between the tolerance catgut embedding and tolerance model groups (P<0.05). There was a statistically significant difference in hippocampal NR1 expression between the tolerance electroacupuncture group and the tolerance model or tolerance catgut embedding group (P<0.05). There was a statistically significant difference in spinal cord CCK expression between the tolerance catgut embedding or withdrawal electroacupuncture group and the tolerance model group (P<0.05).Conclusions Both catgut embedding and electroacupuncture at point Shenshu have a reducing effect on morphine tolerance and withdrawal. The therapeutic effect of electroacupuncture is better than that of catgut embedding.

BACKGROUND: Heme oxygenase-1 (HO-1) promotor region has a pair of dinucleotide(guanosine thymidine, GT) repeats with a lengthy polymorphism, also named microsatellite polymorphism. Experiments in vitro have shown that we can indirectly learn about the level of gene transcription by measuring the number of GT repeats.OBJECTIVE: To investigate if an association exists between restenosis after percutaneous coronary intervention(PCI) and microsatellite polymorphism in HO-1 gene promoter.DESIGN: A case-control study based on the observation of the patients with coronary heart disease after undergoing coronary stenting.SETTING: Wards of the department of cardiology of a university hospital.PARTICIPANTS: A total of 118 patients were admitted from April 1996 to May 2002 at the Department of Cardiology of the First Hospital of Peking University who underwent successful coronary stenting. Inclusion criteria: The patients with coronary heart disease who underwent coronary stent implantation for more than 3 months now came to perform coronary angiography in follow-up. Exclusion criteria: Angiography showed that the stenosis of lumen in diameter in the patients with coronary heart disease was less than 50%and the follow-up in angiography was less than three months. There were 92males and 26 females aged(62±10) years old and the informed consents were obtained. The patients were divided into two groups according to the criteria stipulated by American Heart,Lung and Blood Association: in-stent restenosis(68 cases) and non-restenosis (50 cases).METHODS: DNA of the peripheral blood was isolated from the whole blood. The length of GT repeat was confirmed by PCR amplification and Spreadex Gel electrophoresis. Selected samples were sequenced with Sanger's method.MAIN OUTCOME MEASURES: Microsatellite gene frequency of HO-1promoter and its relationship with restenosis RESULTS: Patients with GT repeats <25 GT in the HO-1 gene promoter on either allele had significantly less often restenosis than patients without (47.5% vs. 68.4% ,P<0.05). After controlling some possible confound ing factorsfor coronary heart diseases, multivariate analysis indicated that still there was a significant difference between the two groups in restenosis rate(odd ratio 0. 418,95% CI: 0. 197 to 0. 887,P<0.05).CONCLUSION: The present study indicated that short(GT) n repeats of HO-1 gene promoter is associated with reduced post-PCI restenosis, which suggests the genetic contribution to in-stent restenosis after stent implantation. It may have important meanings to prevent the occurrence of restenosis.

Objective To investigate the clinical and pathological characteristics of patients with chronic hepatitis B virus(HBV)infection in immune tolerant phase.Methods Ninety-eight chronic HBV carriers in immune tolerant phase were enrolled in this study.The age,gender,serum HBV DNA level,hepatic inflammatory activity and fibrosis,hepatic HBsAg and HBcAg expressions were analyzed.The grade of inflammatory activity and stage of fibrosis were also compared in patients with different levels of serum alanine aminotransferase(ALT).Data analysis was done by chi-square test. Results In 98 patients,83(84.7%)were＜30 years old and 15(15.3%)were≥30.Patients whose mother was HBsAg positive were 48.0%.High levels of serum HBV DNA were found in all patients, with 78.5% were＞1×107 copy/mL.Only 5 cases(5.1%)were G0 of the inflammatory grade;whereas,64 cases(65.3%)were G1,29(29.6%)were G2.There were 56 patients(57.1%)had no significant liver fibrosis;and 23 cases(23.5%)were S1,14(14.3%)were S2,5(5.1%)were S3;none of patients had cirrhosis.The HBsAg and HBcAg in liver tissues were positive in 79(80.6%)and 80(81.6%)cases,respectively.The fibrosis stages of patients with higher ALT levels were significantly greater than patients with lower ALT levels(X2=8.112 3,P=0.043 7).Conclusions Most of patients with chronic HBV infection in immune tolerant phase present mild inflammation in liver,some of them have already developed fibrosis.Therefore,liver pathology is recommended for these patients to help understand the patients' conditions and make correct therapeutic decisions.

This study explored the possibility that the components in melanoma cytoplasm induce murine BMSCs transformation and expression of Melan-A by morphologically observing the changes of BMSCs and immunocytochemically detecting Melan-A in the cells after culturing BMSCs in medium containing melanoma cytoplasm components (MCC). MCC of B16 melanoma cells was prepared and BMSCs were cultured and induced by adding the MCC into culture medium. The cells were morphologically observed and Melan-A was immunohistochemically detected to confirm BMSCs transformation. MCC-induced BMSCs underwent morphological changes. A number of melanin granules appeared in the cytoplasm of the cells and some were released into surrounding areas. Several cells that might come from one cell formed a cluster, and their granules, together with those secreted by other induced BMSCs, formed a so-called "sphere-formed structure". The induced BMSCs expressed Melan-A. We are led to conclude that there might be some factors in the cytoplasm of melanoma cells that might induce BMSCs transformation toward melanogenic cell, or even melanoma.

Objective To investigate the association between cumulative exposure blood to pressure (cum BP) and new-onset chronic kidney disease (CKD).Methods In this prospective cohort study,101 510 employees of Kailuan Group receiving annual health examination during 2006 to 2007 were observed.The participants received the second,third,and fourth annual health examinations during 2008 to 2009,2010 to 2011,and 2012 to 2013 year respectively.Their urinary and serum creatinine were tested,and participants with incomplete SBP,DBP data and CKD were excluded.Further excluding those who somehow failed to take annual health examination,with incomplete data,or new-onset CKD 27 809 participants were selected in the analysis.According to cum BP exposure quintile grouping:Q1 ＜ 3.70 scores;Q2:3.70-6.16 scores;Q3:6.17-8.45 scores;Q4:8.46-10.95scores;Q5 ≥ 10.96 scores.Multivariate Logistic regression was used to analyze the association between cum BP level and new-onset CKD by cum BP exposure quintile grouping.Results The rise of cum BP exposure level caused the increased incidence of CKD.The incidences of CKD in the five quintile groups were 2.59％,3.11％,4.19％,5.81％,and 7.73％ respectively (P＜ 0.01).Compared with Q1 group,multivariate logistic regression analysis showed that after the adjustment of age,gender,education,income,smoking,drinking,BMI,FBG,TC,TG,LDL,HDL,UA and CRP,the incidences of CKD gradually increased in the Q2,Q3,Q4,and Q5 cum BP quintile groups,and OR(95％CI) values were 1.08(0.86-1.35),1.26(1.01-1.58),1.57(1.27-1.95),1.78(1.43-2.21) respectively (P for trend ＜0.01).Similar results were obtained in different genders.For each single point increase of cum BP exposure level,the incidence of CKD increased 6％ in the general population (P for trend ＜ 0.01),increased 8％ in male (P for trend ＜ 0.01),and 3％ in female (P for trend=0.12).Conclusion As the cumulative exposure to blood pressure increases,the risk of CKD incidence rises,especially in men.

Objective To explore the effects of application of self-made assessment card for spinal nerve motor function in clinical nursing.Methods An assessment card for spinal nerve motor function was designed and produced according to "spinal cord injury grading standards" by American Spinal Injury Association(ASIA).A total of 40 nurses working in orthopedic ward of our hospital were selected as study subjects,and divided into the experimental group and the control group with 20 nurses in each group.Theoretical and practical training regarding spinal nerve motor function was provided to nurses in both groups.Then totally 398 patieuts with spine or spinal cord diseases hospitalized in our orthopedic ward were recruited from June to September 2016 as subjects for assessment.The experimental group used self-made assessment card for spinal nerve motor function as guidance;the control group performed routine assessment for spinal nerve motor function.Results There were no significant differences between the experimental group and the control group in scores of theoretical and practical examinations (P＞0.05);compared with the control group,the error of assessment in the experimental group was reduced by 9.5％,missed assessment rate decreased by 16.2％;and the time for assessnent in the experimental group was significantly shorter than that in the control group(P＜0.05).Conclusion The assessment card for spinal nerve motor function can reduce the error of assessment,save the time for assessment,enhance the capacity of specialist nurses and improve work efficiency.

Objective To explore the effects of application of standard evaluation process of spinal cord motor function in patients with thoracic or lumbar diseases. Methods Selected 60 patients with thoracic and lumbar disease treated in the orthopedic ward of Henan Provincial People's Hospital from April 2016 to June 2016 as the experimental group. We retrospectively analyzed 60 cases of patients with thoracic or lumbar diseases treated with routine nursing evaluation process admitted between January to March 2016. We compared before and after the standardization evaluation process of spinal cord motor function, the theory and operation achievements of nurses, satisfaction of doctors with nurse specialist ability, mean hospitalization days and average cost of two groups.
