Moreover, attachment anxiety measured by ECR has negative correlation with model-of-self measured by RQ (P

Objective To investigate the clinical efficacy of acupuncture at point Shanzhong(CV17) plus cupping on Back-Shu points in treating migraine. Methods Seventy migraine patients were randomly allocated to treatment and control groups, 35 cases each. The control group received conventional acupuncture and the treatment group, acupuncture at point Shanzhong(CV17) plus cupping on Back-Shu points in addition. The VAS score was counted in the two groups before and after treatment. The clinical therapeutic effects were compared between the two groups. Results The cure and marked efficacy rate and the total efficacy rate were 88.6%and 100.0%, respectively, in the treatment group and 62.9%and 94.3%, respectively, in the control group. There was a statistically significant difference in the cure and marked efficacy rate between the two groups (P＜0.05). There was a statistically significant pre-/post-treatment difference in the VAS score in the two groups (P＜0.05). There was a statistically significant post-treatment difference in the VAS score between the treatment and control groups (P>0.01). The clinical symptom improvement rate was (78.3±10.6)%in the treatment group and (49.8±11.2)%in the control group;there was a statistically significant difference between the two groups (P＜0.01). Conclusion Acupuncture at point Shanzhong plus cupping on Back-Shu(CV17) points is an effective way to treat migraine.

Objeetive To evaluate the protective effects of decorin on the inner blood-retinal barrier function under high-glucose plus hypoxia conditions,and explore its potential mechanism.Methods The human umbilical vein endothelial cells (HUVEC) were cultured,and the effect of decorin with different concentrations on HUVEC viability was determined by using the cell counting kit-8 assay (CCK-8).At different hours after incubation under high-glucose plus hypoxia conditions (25 mmol · L-1 D-glucose + 100 μmol · L-1 CoCl2),the suppression effects of various concentrations of decorin on the vascular endothelial growth factor (VEGF) expression of HUVEC was detected by enzyme-linked immunosorbent assay (ELISA).HUVEC were divided into normal control group (5.5 mmol · L-1 D-glucose),high-glucose plus hypoxia group (25 mmol · L-1 D-glucose + 100 μmol · L-1 CoCl2),mannitol control group(5.5 mmol· L-1 D-glucose +19.5 mmol · L-1 mannitol) and decorin treatment group (25 mmol · L-1 D-glucose+ 100 μmol · L-1 CoCl2 + 100 nmol · L-1 decorin).HUVEC barrier function was evaluated by detecting transepithelial electrical resistance (TER) and permeability of fluorescein isothiocyanate-dextran (FITC-dextran).The content of tight junction proteins (claudin-5,occludin,and ZO-1) and p38 mitogen-activated protein kinase (MAPK) phosphorylation were examined by Western blotting.Results According to the results of CCK-8,the survival rates of HUVEC in all groups were more than 90％,different concentrations of decorin showed no significant effect on HUVEC survival (all P ＞ 0.05).According to the results of CCK-8 and ELISA,the stimulation of hypoxia for 48 hours and 100 nmol · L-1 decorin was taken as the condition of further experiment.At 14 days,TER of HUVEC reached its peak of (170.67 ±9.07) Ω.TER of high-glucose plus hypoxia group (97.33 ±6.11)Ω was significantly lower than that of decorin treatment group (157.67 ± 11.72)Ω (P ＜0.05).The FITC-dextran permeability of high-glucose plus hypoxia group increased to (2.12 ±0.07) times of normal control group(P ＜0.05).Decorin reversed this effect to (1.16 ± 0.03) times of normal control group (P ＜ 0.05).The expression of claudin-5,occludin and ZO-1 in high-glucose plns hypoxia group were 0.38 ±0.05,0.43 ±0.02,0.25 ± 0.02,compared to the normal control group (0.72 ±0.05,0.90 ±0.01,0.75 ±0.02),there were statistical differences (all P ＜0.05).The expression of claudin-5,occludin and ZO-1 m decorin treatment group were 0.65 ±0.08,0.87 ±0.03,0.60 ±0.01,there were statistical differences compared with high-glucose plns hypoxia group (all P ＜0.05).The ration of p-p38 MAPK/p38 MAPK in high-glucose plus hypoxia group (0.88 ± 0.02) was increased,while the decorin treatment group (0.58 ± 0.04) reached the level of the normal control group (0.56 ±0.02),there was statistical difference compared with high-glucose plns hypoxia group (P ＜0.05).Conclusion Decorin can protect the HUVEC barrier function under high-glucose plus hypoxia conditions and inhibit the activation of p38 MAPK signaling pathway.So it may be used to treat diabetic retinopathy.

Objective To investigate the image quality and radiation dose of 640-slice CT coronary arteriography(CTCA) with adaptive iterative dose reduction three-dimensional (AIDR3D)reconstrucction algoritym.Methods 640-slice CTCA with auto-matic exposure was performed on 84 consecutive patients.The original image data were reconstructed with AIDR3D and the filtered back-projection (FBP)algorithms at the image postprocessing workstation.Two experienced radiologists without knowing clinical information and reconstruction algorithms independently measured and calculated the image noise,signal-to-noise ratio and contrast-to-noise ratio with AIDR3D and FBP reconstruction algorithms.The qualitative image quality was assessed by using the 4-point scale.The radiation dose was calculated based on dose-length product exported on CT scanner.The quantitative and qualitative im-age quality with two kinds of reconstruction algorithm was analyzed statistically.Results The CTCA image noise was (27.20± 4.40)HU with AIDR3D and (60.00±12.40)HU with FBP,which with AIDR3D was decreased by 46.10% than that with FBP;the signal-to-noise ratio was 21.10 ± 5.10 with AIDR3D and 11.40 ± 2.80 with FBP,which with AIDR3D was increased by 84.70% than that with FBP;the contrast-to-noise ratio was 24.70±5.10 with AIDR3D and 13.50±3.20 with FBP,which with AIDR3D was raised by 82.20% than that with FBP,the differences in 3 indexes between the two kinds of reconstruction algorithm were statistically significant(P < 0.05 ).The CTCA qualitative image quality scores of proximal,middle and distal parts with AIDR3D were (3.90±0.30),(3.70±0.50)and (3.60±0.60)respectively,which all were higher than (2.60±0.60),(2.30± 0.60)and (2.10±0.70)with FBP respectively,the differences in 3 items between 2 kinds of algorithm had statistical significance (P <0.05).The total segments which could be used to diagnose the CTCA images with AIDR3D and FBP algorithms were 1 216 segments (96.50%)and 504 segments (40.00%),respectively,the difference had statistical significance(P <0.05).The mean ef-fective radiation dose was (2.10±1.00)mSv.Conclusion 640-slice CTCA with AIDR3D reconstruction algorithm not only signifi-cantly reduces the image noise than the conventional FBP algorithm,improves the quantitative and qualitative image quality,but also decreases the effective radiation dose.

Objective To detect the impairment of response inhibition and working memory in patients with alcohol dependence.Methods A total of forty-eight alcohol dependent patients and fifty age,gender,IQ,education matched controls were recruited.Neuropsychological tests were applied to measure the differences of response inhibition and working memory between the two groups.Results In the response inhibition task,the patient group had more commission errors ((7.02± 3.48) vs (3.45± 1.52)) and longer reaction time ((605.45 ± 142.56)ms vs (435.72±51.18)ms) compared to the control group (t=6.534,P=0.000; t=7.781,P=0.000).In the spacial working memory task,the patient group also had more commission errors ((4.58± 3.45) vs (0.43± 0.88)) and longer reaction time((10566.16±2455.61) ms vs (9185.44±2677.52) ms) than control (t=8.085,P =0.000; t=2.657,P=0.009).Conclusion There are significant deficiencies in response inhibition and working memory in patients with alcohol dependence.

Hereditary spastic paraplegia is a heterogeneous group of genetic neurodegenerative disorders of the nervous system. It is classified into four subtypes based on the mode of inheritance; and among them, most autosomal recessive hereditary spastic paraplegia cases are due to type SPG11 and SPG15 gene mutations. Autosomal recessive hereditary spastic paraplegia cases with SPG30 gene mutation have never been reported in China. Herein, we present our experience with a case of hereditary spastic paraplegia with SPG30 gene mutation in our hospital from North East China. In this patient we detected a missense mutation of c.499 C>T (p.Arg167Cys) in gene KIF1A, a causative gene of type SPG30.

Objective To discuss the levels of evidence provided by different study designs.Methods Websites of N Engl J Med, JAMA, Lancet, and BMJ were accessed to identify research articles (systematic review and meta-analysis included) published in 2009. A standardized data collection form was established using Epidata 3. 1 software to extract the "title", "country of lead author", "clinical problem" (such as treatment, diagnosis, etc. ) and "study design" of eligible studies. Descriptive statistics was conducted with SPSS 13.0. Results Over all, 844 studies were included, among which 35.7% were RCT,9. 4% systematic review and Meta-analysis, and 54. 9% other types of studies. Regarding clinical problems,34. 2%, 19. 7%, 13.7%, 6. 0% and 5. 1% of the included researches addressed the issues of treatment,etiology/risk factors, prevention, disease frequency and prognosis, respectively. The study designs that were most frequently adopted to explore these problems were RCT (70.6%), cohort study (44. 6% ), RCT (68. 1% ), cross-sectional study ( 56. 9% ), and cohort study ( 93.0% ), respectively. Conclusions High-level evidence does not come exclusively from RCT and systematic review, as each type of study may have its unique value in health related research. The clinical problem of interest, the previous work that has been done to approach the same issue, as well as other factors should be taken into account when deciding whether the selected study design is appropriate.

Objective:In order to compare the effect of ascending medial open-wedge high tibial osteotomy and descending medial open-wedge high tibial osteotomy on patellar height.Methods:Our group analyzed 77 patients of medical cases which were closely associated with medial open-wedge high tibial osteotomy for the treatment of knee varus deformity and medial compartment osteoarthritis from May 2011 to December 2018 and 77 cases were effectively followed up, including 36 males and 41 females with an average age of 59.4±10.5. By the way, there are 51 cases of ascending osteotomy and 26 cases of descending osteotomy. During these treatment, we adopted some scientific methods full-length standing anteroposterior radiograph,Miniaci method, Insall-Salvati index (ISI), Caton-Deschamps index (CDI) and Blackburne-Peel Index (BPI) to measure the corresponding parameters and changes in patellar height (PH) at different stages.Results:77 patients were enrolled, the mean follow-up time was 20.6 months (range, 12-60 months), ascending and descending high tibial osteotomy (HTO) show the average degree of varus correction (10.43°±2.67° and 11.16°± 2.80°) respectively. And at the same time, in these cases of ascending HTO, PH decreased by 8.1% (CDI method), 2 cases of low PH (the patellar height decreased by 10%, which is the low patellar) were measured (ISI method), 7 cases of low PH occurred (CDI and BPI). Instead, PH decreased by 4.5% (CDI method) in descending HTO,the difference was significant ( t=2.101, P=0.040). 22 cases of ascending HTO with varus correction less than 10 degrees, the PH decreased by 6.9%. By the way, the ISI method did not detect the occurrence of low PH, but we found one by CDI and BPI. The 29 cases with varus correction of more than 10 degrees in ascending HTO, and PH decreased by 10.4%. There were 2 low PH (ISI method), and 6 low PH (CDI and BPI), the difference was significant ( t=2.310, P=0.028). Conclusion:In ascending HTO, the low PH is closely related to the degree of varus correction. Conversely, The descending HTO did not influence PH.

Objective To investigate the correlation between family cohesion and adaptability and quality of life in patients with enterostomy. Methods Using Chinese version of Family Adaptability and Cohesion Scale (FACESⅡ-CV) and Chinese version of Stoma-Quality of Life (STOMA-QOL-C) to investigate the status of family cohesion and adaptability, family type and their impact on quality of life of 110 patients with enterostomy. Results Scores of family cohesion and adaptability averaged 59.15 ± 11.94, 47.32 ± 9.40,were significantly lower than 63.90 ± 8.00 and 50.90 ± 6.20 in the norm,and the difference was statistically significant (t=-4.171,-3.990, P<0.01).The family cohesion was positively correlated with the score of quality of life, social interaction and psychological burden(r=0.274, 0.284, 0.263, P<0.05), and the family adaptability was positively correlated with the score of quality of life,social interaction and psychological burden(r=0.316, 0.338, 0.228, P<0.05 or 0.01). The balance type family was 30 cases;scores of quality of life averaged 45.10±7.26, the intermediate type family was 50 cases;scores of quality of life averaged 43.48±9.98, the extreme type family was 28 cases;scores of quality of life averaged 43.37 ± 16.68, and difference between the three was no statistically significant(F=0.442, P=0.665). Conclusions In the nursing process of patients with enterostomy, health care workers should pay attention to improve family cohesion and adaptability, as to achieve the purpose of improving the quality of life of the patients.

BACKGROUND:Stem cells have been shown to not only replace damaged cells, but also secrete trophic factors, bringing a bright future for the treatment of clinical spinal cord injury.
OBJECTIVE:To review the latest advances of bone marrow mesenchymal stem cells in animal and clinical research.
METHODS:A computer-based search of Kjmed and Wanfang databases was done for relevant articles published from April 2004 to April 2014 using the keywords of“stem cells, spinal cord injuries, embryonic stem cells, neural stem cells, mesenchymal stem cells”in English and Chinese, respectively.
RESULTS AND CONCLUSION:Total y 2 745 articles were initial y retrieved, and only 50 articles were included in result analysis. Bone marrow mesenchymal stem cells have become one of the most promising sources of stem cells in the treatment of spinal cord injury. Although the bone marrow mesenchymal stem cellin the treatment of spinal cord injury is stil in its infancy, it has certain effects on the repair of spinal cord injury. The mechanism of action of bone
marrow mesenchymal stem cells in the treatment of spinal cord injury is possibly related to the substitution effect, neurotrophic effects, suppression of the immune response and promoting axonal regeneration.
