Intracellular Ca2+ concentration of treatment with Eqi was higher evidently than that of control (P

Background Researches have suggested that the defocus can induce the change of static visual acuity,but whether it produce influence on dynamic visual acuity is not clear.Objective This study was to investigate the impact of myopic defocus on static visual acuity and dynamic visual acuity and explore the essential difierence between static visual acuity and dynamic visual acuity. Methods Forty volunteers were enrolled in this trial.including 20 adults with the age of 27.4±1.64 years and 20 children with the age of 11.70+1.49 years.All the eyes of subjects received regular examined to excluded the eye disease with the best corrected vision of ≥1.0 D,astigmatism of ≤0.75 D and anisometropia ＜1.50 D.+1.00 D,+1.50 D,+2.00 D,+2.50 D slasses were ware respectively for the defocus on the foundation of full correction.Dynamic visual acuity was inspected by using selfmade DVA-I training software.and static visual acuity wag tested by static visual acuity chart (Precision Vision,CAT.NO.2125).This clinical trial complied with the Helsinki Declaration and obtained the approval of Ethic Committee of Wenzhou Medical College.Written informed consent was received from each individual prior to the protocol. Results The dynamic and static visual acuities were gradually decreased with the elevation of defocus (F=506.907,P=0.000).No significant differences were found between static visual acuity and dynamic visual acuity in adult or children at various defocus(P＞0.05).The regression linear analysis showed that a positive correlation between static visual acuity with defoeus(R2=0.819,t=26.72,P=0.000) or dynamic visual acuity with defoeus(R2=0.826,t=27.42,P=0.000).The slope and intercept between defocus with static visual acuity were steeper than that between defocus and dynamic visual acuity (slope:F=34.18,P=0.000;intercept:F=1005.56,P=0.001). Conclusion The effect of defocus on static visual acuity is different from that of dynamic visual acuity.It could be speculated that dynamic visual acuity is related not only to refractive systems but also other factor.

Objective To investigate the relationship between aggrecan and YKL-40 in knee articular cartilage of Sprague-Daw-lay(SD) rats with osteoarthritis (OA) .Methods Fifty-six healthy SD rats were randomly divided into 7 groups ,8 cases per group . The one side of knee joint was randomly selected for performing the anterior cruciate ligment transection (ACLT) and establishing the OA model .The rats in one group were randomly killed on the day of operation and at postoperative 0 ,2 ,4 ,8 ,12 ,16 ,20 weeks . The femoral condyle cartilage samples at different time periods in the operated side were collected for conducting safranin O /fast green staining and HE staining .Meanwhile ,the OA pathological grade was made out according to the modified Mankin scale .The expression of aggrecan and YKL-40 in the cartilage with different stages of OA were analyzed by the immunohistochemistry meth-od ,and the status of expression were measured by average optical density (AOD) .The correlation between aggrecan and YKL-40 was analyzed .Results With the aggravation of OA ,the expression of aggrecan was gradually reduced and the expression of YKL-40 was gradually increased .The differences during the early ,middle and late phases of OA had statistical significance (P<0 .05) .

Objective To compare clinical outcomes in cardiac transplant recipients treated with individualized dosing (ID) and fixed dosing (FD) of mycophenolate mofetil (MMF).Methods Fortyeight de novo cardiac transplant patients in ID group received MMF (2.0 g/day) in combination with calcineurin inhibitors and prednisone.The MMF dosages were adjusted individually based on clinical events and MPA trough levels (MPA-C0).The target range of C0 was maintained within 2.0-4.0rng/L.The FD group included 55 recipients retrospectively from the transplant database who were also treated with MMF (2.0 g/day).In this group,the MMF dose adjustment was performed empirically according to clinical events only.All of the follow-up data were collected up to 12 months post-transplantation.Results The follow-up rate was 95.8％ and the mean MPA-AUC0-12 was (54.37± 17.03) rng h-1 L-1 in the ID group.The mean MPA-C0 on the day 7 post-transplantation was significantly higher in the ID group than that at 12th month [(3.44 ± 0.58) mg/L vs.(2.79 ± 0.54)mg/L] (P＜0.05).The dose of MMF was significantly lower in the ID group at 4th week posttransplantation than in control group [(1.49± 0.48) g/day vs.(1.96 ± 0.39) g/d] (P＜0.05),while there was no significant difference at 12 th month post-transplantation [(1.61 ± 0.77) g/day vs.(1.68 ± 0.84) g/day] (P＞ 0.05).No significant difference was found in the incidence of acute rejection episode between two groups (8.7％ vs.9.1％,P＞0.05).57.6％ of overall side effects were observed within one month postoperatively,and the incidence of MPA-related side effects was significantly lower in the ID group than in the control group (47.8％ vs.67.3％,P＜0.05).Conclusion It was demonstrated that individualized use of MMF based on therapeutic drug monitoring may prevent MMF-related side effect and appears to be valuable to optimize the treatment of cardiac transplantation.

Background: There are obvious changes in neuropeptides from plasma and cerebrospinal fluid in patients with vascular dementia (VaD), and regulating the levels of neuropeptides is a key for prevention and treatment of VaD. Objective: To observe the clinical efficacy of moxibustion at head-points in treatment of vascular dementia (VaD), and assess its effects on memory-related neuropeptides. Design, setting, participants and interventions: A total of 65 VaD patients from Acupuncture Hospital, Anhui University of Traditional Chinese Medicine, were randomly divided into moxibustion group (33 cases) and Western medicine group (32 cases). Patients in the moxibustion group were treated with indirect moxibustion with common monkshood cake for 20 min. Patients in the Western medicine group were orally administered piracetam tablets, 0.8 g for three times a day. One treatment course was 4 weeks, and they were treated for 4 treatment courses. Main outcome measures: The scores of Hasegawa's Dementia Scale (HDS), Mini-Mental State Examination (MMSE), and Activity of Daily Living Scale (ADL), as well as the levels of learning and memory-related neuropeptides from cerebrospinal fluid such as somatostatin (SS) and arginine vasopressin (AVP) were measured before and after treatment in the two groups. Results: Total response rate was significantly higher in the moxibustion group than in the Western medicine group (P<0.01). There were significant differences in scores of HDS, MMSE and ADL between before and after treatment in the two groups(P<0.05 or P<0.01). After treatment, the scores of HDS, MMSE and ADL in the moxibustion group were more improved as compared with those in the Western medicine group (P<0.05 or P<0.01). The levels of SS and AVP after treatment were higher than those before treatment in the two groups(P<0.01). After treatment, the increased levels of SS and AVP were higher in the moxibustion group than in the Western medicine group (P<0.01). Conclusion: Moxibustion is effective in improving the clinical symptom scores and regulating the levels of neuropeptides associated with learning and memory in VaD patients.

Objective To explore coping strategies and influence factors in primary glaucoma patients through describing characteristics of their coping strategies.Methods From November 2007 to June 2008,data were collected from 120 primary glaucoma patients in three hospitals in Guangzhou and Shenzhen.The final sample consisted of 100 patients and the data underwent analysis.Results Among different coping styles of primary glaucoma patients,facing was lower than norm,avoiding and yielding were higher than norm.The factors related to coping style were age,different cohabitant,different economic condition,different occupation,different educational level and health payment mode.Conclusions Primary glaucoma patients usually took avoiding or yielding coping styles.Nurses should help patients with low income and education background to face the disease positively.Besides,fully consideration should be given to patients with different age,at the same time,marriage and family support should also exert active function.

Objective To evaluate the clinical efficacy of different treatments on non-small cell lung cancer (NSCLC) patients with brain metastases and to explore the influential factors of the prognosis.Methods The NSCLC patients with brain metastases treated from Jan.2010 to Dec.2011 were follow-up.The survival time and influences resulted from the treatments were analyzed.Results The average survive time of these patients was (11.93±5.53) months,and the median survive time was 11 months.The 6-month,1-year and 2-year overall survival rates were 90.7 ％,41.1％ and 6.4 ％,respectively.Multivariate analysis showed that control of extracranial lesions,Kamofsky score,target therapy and age were independent predictive factors of survival,and the OR value were 0.358 (95 ％ CI0.217-0.593),0.302 (95 ％ CI 0.182-0.502),0.170 (95 ％ CI 0.098-0.296) and 1.635 (95 ％ CI 1.010-2.647),respectively (all P ＜ 0.01).Conclusions Radiation therapy is an effective treatment on non-small cell lung cancer with brain metastases.Biological target therapy can effectively improve survival.The survival time also is correlated with age,Karnofsky score and control of extracranial lesions.

A spectrophotometric method for the determination of calcium in milk, hair and urine was developed using metal complezing dye orthocresolphth-alein complexone(OCPC).The organic matter in the tested sample was destroyed by digestion. An aliquot of the digested solution was mixed with color developing reagent, alkaline OCPC, cantaining 8-quinolinol to suppress interference such as magnesium, and the absorbance was measured at 570 nm.The coefficients of variation were 0.87, 3.6 and 1.2% for milk, hair and urine samples; and the analytical recoveries of calcium from milk, hair and urine averaged 100.4, 101.0 and 98.5% respectively. The calcium content of milk and hair determined by this method was closely correlated with that of the ICP-AES method (r =0.994, p

Objective:To study the diagnostic value of MR diffusion weighted imaging (DWI) and CT and MR perfusion imaging in patients with different degrees of liver cirrhosis.Methods:A total of 60 patients with liver cirrhosis,who were treated in Ziyang Hospital of West China Hospital of Sichuan University from August 2015 to February 2017 were selected.According to the Child-Pugh classification,32 cases of grade A were mild cirrhosis (denoted as group A),16 cases of grade B and 12 cases of grade C were moderate to severe cirrhosis (denoted as group B),30 healthy volunteers were selected as group C in the same period.All the subjects in the three groups were examined by DWI,CT and MR perfusion imaging.The ADC value,hepatic portal perfusion ratio [SSr (CT) and SSr (MR)] were compared among the three groups,and Spearman correlation analysis was used to analyze the correlation between the indexes.Results:There was no significant difference in ADC values among the three groups (P＞0.05),and the ADC values of group A and B were lower than those of group C,but the difference was not statistically significant (P＞0.05).There was no significant difference in ADC values between group A and B (P＞0.05).The levels of SSr (CT) and SSr (MR) in the three groups were compared,the difference was statistically significant (P＜0.05);the levels of SSr (CT) and SSr (MR) in group B were significantly higher than those in group A and C,the difference was statistically significant (P＜0.05).There was no significant difference in the levels of SSr (CT) and SSr (MR) in group A and C (P＞0.05).Spearman correlation analysis showed that SSr (CT) was positively correlated with SSr (MR) in the patients with liver cirrhosis (r=0.687,P=0.000).Conclusion:CT and MR perfusion imaging can reflect the lesion degree of liver cirrhosis,and diagnostic effects of the two are better than DWI imaging,which is worthy of clinical promotion.
