ABSTRACT
Objective To investigate the effect of miR-130a targeting phosphase and tensin homology deleted on chromosome ten(PTEN)/phosphoinositide 3 kinase(PI3K)/protein kinase B(AKT)pathway on renal tissuecell apoptosis in diabetic kidney disease(DKD)rats.Methods The DKD rat model was constructed by feeding high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin(STZ).72 rats were divided into normal control group(NC),DKD model group(DKD),miR-130a agonist negative control group(NC agomir),and miR-130a agonist group(miR-130a agomir),miR-130a agomir+ PTEN overexpression negative control group(miR-130a agomir+pcDNA),and miR-130a agomir+ PCDNA-PTEN overexpression group(miR-130a Agomir + PCDNA-PTEN),with12 rats in each group.Urinary microalbumin kit was used to detect 24 h urine albumin(UAlb).Fasting blood glucose(FBG),serum creatinine(Scr)and blood urea nitrogen(BUN)were detected by automatic biochemical analyzer.Pathological changes of renal tissue were detected by HE staining.The levels of serum IL-6 and TNF-α were detected by ELISA.The apoptosis of renal tissue was detected by TUNEL staining.The expression of miR-130a was detected by qRT-PCR,and the expression of B-cell lymphoma-2-associated X protein(Bax),B-cell lymphoma-2(Bcl-2)and PTEN/PI3K/AKT pathway were detected by Western blot.Dual luciferase reporter gene experiment was used to verify the targeting relationship between miR-130a and PTEN.Results Compared with DKD and NC agomir groups,24 h UAlb,FPG,Scr,BUN,IL-6,TNF-α,renal cell apoptosis rate,Bax protein expression and PTEN protein expression in miR-130a agomir group were decreased(P<0.05).The expressions of miR-130a,Bcl-2,p-Akt/AKT protein were increased(P<0.05).Compared with miR-130a agomir group,24 h UAlb,FPG,Scr,BUN,IL-6,TNF-α,renal cell apoptosis rate,Bax protein expression and PTEN protein expression were increased in miR-130a agomir+pcDNA-PTEN group(P<0.05).The expression of Bcl-2,p-Akt/AKT protein decreased(P<0.05).Conclusion Overexpression of miR-130a may inhibit renal cell apoptosis in DKD rats by down-regulating PTEN to activate PI3K/AKT pathway.
ABSTRACT
Objective·To investigate the causal relationship between atrial fibrillation(AF)and cognitive impairment.Methods·A two-sample Mendelian randomization(TSMR)analysis was used to assess the potential causality of AF on cognitive dysfunction.Single nucleotide polymorphisms(SNPs)strongly associated with AF were extracted as instrumental variables by using a dataset of a large-scale genome-wide association study(GWAS)on AF.The associations of SNPs with Alzheimer's disease dementia,Parkinson's disease dementia,vascular dementia,Lewy body dementia,frontotemporal dementia,undefined dementia,and overall cognitive function assessment were extracted separately from publicly available GWAS data on cognitive dysfunction.The inverse variance-weighted(IVW)method was used for the main analysis,and sensitivity analyses were conducted by using Cochran's Q test,MR-Egger regression,and leave-one-out method.To verify the robustness of the results,replicate analyses and meta-analyses were performed by using different GWAS data.Results·In the initial analysis,101 SNPs were extracted as instrumental variables from a meta-analysis of a genome-wide association study involving up to 1 030 836 individuals.The IVW analysis showed no evidence for causal associations between AF and dementia[dementia(OR=1.032;95%CI 0.973-1.094;P=0.290),Parkinson's disease dementia(OR=1.004;95%CI 0.780-1.291;P=0.977),vascular dementia(OR=1.123;95%CI 0.969-1.301;P=0.125),or unspecified dementia(OR=1.013;95%CI 0.910-1.129;P=0.807)].In the replication analysis,27 SNPs were extracted as instrumental variables from the FinnGen AF GWAS data,and the 1VW analysis were consistent with the initial analysis[cognitive function(OR=0.999;95%CI 0.982-1.016;P=0.874),Alzheimer's disease dementia(OR=0.977;95%CI 0.943-1.012;P=0.193),Lewy body dementia(OR=1.014;95%CI 0.898-1.145;P=0.826),or frontotemporal dementia(OR=0.996;95%CI 0.745-1.333;P=0.980)].Both Mendelian randomization analyses and meta-analyses showed no evidence of an association between genetically predicted AF and different types of dementia or overall cognitive function assessment.MR-Egger regression suggested no horizontal pleiotropy and leave-one-out analysis showed stable results after individually removing each SNP.Conclusion·No evidence of a causal relationship between AF and cognitive impairment was found.The associations observed in observational studies can be partially attributed to confounding factors such as shared biology or co-morbidities.
ABSTRACT
Neuromyelitis optica spectrum disorder (NMOSD) is an autoimmune demyelinating disease in central nervous system,mainly involving the optic nerves and spinal cord.NMOSD is a relapsing disease with severe residual disability,therefore,prevention of attacks is critical for the preservation of visual and neurologic function.The conventional immunosuppressants,including prednisone,azathioprine,mycophenolate mofetil and methotrexate,can be used to prevent relapse of NMOSD.And immunotherapeutics such as rituximab,tocilizumab and eculizumab are increasingly used in recent years.This review summarizes the current status and the future strategies in treatment of NMOSD based on the progress of NMOSD pathogenesis.
ABSTRACT
Objective To explore the static postural balance in individuals with or without functional ankle instability (FAI)by identifying and quantifying the spatial characteristics of center of pressure (COP),as well as rambling and trembling trajectory properties.Methods Twelve FAI patients was selected into the FAI group,while another 14 healthy students were chosen into the control group.The single-leg standing test with and without vision was conducted on the unstable side of the FAI group and the non-dominant side of the control group 3 trials with each trial lasting 30 s.The displacement of COP and the time and frequency domain of rambling and trembling were analyzed and compared between the two groups.Results There was no significant difference in the displacement of COP with opened eyes(P>0.05).The area and the anterior-posterior length of COP of the FAI group were larger than those of the control group with eyes closed (P<0.05).For the rambling and trembling trajectory,no significant differences were found in all the time domains between the two groups with eyes open or closed(P>0.05),except the mean sway amplitude(MSA)(P<0.05).Moreover,the mean square root and standard deviation of MSA of the FAI group were significantly bigger than the control group(P< 0.05).Significant differences were found in the MSA frequency between open and closed eyes(P>0.05),but not between the FAI and control groups(P<0.05).Conclusions The FAI patients are weaker than healthy people not only in the peripheral control,but also in the central control of the static postural balance.Therefore,injuries in the central neural system must also be considered when analyzing the reason for FAI.The imbalance of the FAI patients can be avoided by opening eyes.

ABSTRACT
BACKGROUND: Jieyuanshen decoction (JYAS-D) - a traditional Chinese medicine was invented by Professor Nie based on classic formulas, chaihu jia longgu muli decoction has been proved as having favorable curative effects on depression in clinical practices. The aim of this study was to investigate the antidepressant effects and its molecular mechanism of JYAS-D. MATERIALS AND METHODS: The model of depression was established by Chronic Unpredictable Stress. Different doses (8.2 g/kg, 16.3 g/kg, 32.7 g/kg) of JYAS-D was orally administered; Fluoxetine was orally administered with 10mg/kg. All treatments lasted for 28 days. Sucrose preference and open-field tests were adopted to observe the behavior of rats. OPA (ortho-phthalaldehyde) derivatization method was used to detect the contents of amino acid neurotransmitter. RIA (Radiation immunity analysis) method was used to measure the serum concentrations of CORT (Corticosterone), ACTH (Adrenocorticotropic hormone) and CRH (Corticotropin-releasing hormone). ELISA (Enzyme linked immunosorbent assay) method was adopted to examine the contents of Glucocorticoid receptor (GR) and Mineralocorticoid receptor (MR) in hippocampus. RESULTS: Compared with the model group, sucrose preference was increased in all treatment groups. The concentration of serum CORT was reduced in the middle dose of JYAS-D and control groups; the concentration of serum ACTH was reduced in the low and high-dose of JYAS-D; the concentration of serum CRH was reduced in the middle and high-dose of JYAS-D. The content of hippocampus GR was increased in the middle and high-dose of JYAS-D; the content of hippocampus Glu (Glutamic acid) was reduced among the low, middle and high-dose of JYAS-D and fluoxetine group, the ratio of Glu/γ-GABA (y-aminobutyric acid was reduced in the low and high-dose of JYAS-D. CONCLUSION: JYAS-D had a significant antidepressant-like effect on rat model through regulating serum concentration of CORT, ACTH and CRH, increasing the content of hippocampus GR and regulating the equilibrium of amino acids neurotransmitter.

BACKGROUND:Most bone marrow mesenchymal stem cel s are infused intravenously and have very low efficiency of homing to the bone marrow. However, cel infusion via the femoral approach is little reported. OBJECTIVE:To explore the distribution of luciferase gene modified red fluorescent protein transgenic bone marrow mesenchymal stem cel s in vivo through different infusion routes. METHODS:Luciferase gene modified bone marrow mesenchymal stem cel s at different gradients (5×106, 1×106, 1×105, 1×104) were seeded or injected into the in vitro pore plate or free femurs to observe the fluorescence imaging and select the best concentration of cel s. Luciferase gene modified bone marrow mesenchymal stem cel s at the best cel concentration were injected into the mice via the femur and the tail vein, respectively. The distribution of fluorescence and cel number in the mice were explored by using bioluminescence, pathological examination, flow cytometry and quantitative PCR. RESULTS AND CONCLUSION:Ex vivo fluorescence intensity of luciferase gene modified bone marrow mesenchymal stem cel s was positively correlated with the cel concentration;fluorescent cel s in vivo appeared in the femur first and then quickly spread to the lungs in the femur group, while fluorescent cel s in the tail vein group spread to the lungs quickly after cel infusion. Fluorescent cel s could be seen in the spleen, liver and other organs 24 hours later in the two groups. The distribution and migration of cel s in mice could be observed successful y by bioluminescence;5 minutes after cel infusion, the lungs of mice in the two groups began to emit fluorescence that could spread to the liver, spleen and other tissues 24 hours later, and the fluorescence intensity reached its peak after 15 minutes. The distribution of bone marrow mesenchymal stem cel s in mice had no significant difference between the femur group and the tail vein group. To conclude, cel injection through the bone marrow cavity and tail vein fails to promote the homing of bone marrow mesenchymal stem cel s to the bone marrow.

ABSTRACT
BACKGROUND:At present, the study to balance ability of functional ankle instability patients is less. The balance ability deficiency may also be one of the important reasons for ankle repeated injury, so the research can effectively reduce the damage probability. OBJECTIVE:To explore the static balance ability characteristics of functional ankle instability patients. METHODS:Ten male subjects with unilateral functional ankle instability were enrol ed as the experimental group in the study, and other 10 healthy match-paired subjects were served as the control group. Their static balance ability was measured under double feet standing and single foot standing using win-pod system, the double feet testing lasted for 30 seconds and the single foot testing lasted for 10 seconds. Evaluation parameters of balance ability were obtained. RESULTS AND CONCLUSION:During double feet testing, there were no significant differences in balance ability parameters between the experimental group and the control group whether eyes be opened or closed (P>0.05), but the index values of double feet testing were obviously less than those of single foot testing. So we concluded that in the double feet standing, there was no significant difference in the static balance ability between functional ankle instability patients and normal persons. Moreover, the static balance ability of double feet was better than that of single feet. In the single foot standing of the affected foot, the static balance ability of functional ankle instability patients was slightly worse than that of the normal persons, especial y with eyes closed. Comparison of the average swing between the X-axis and Y-axis found that in the process of maintaining balance posture, the swing direction of the body center of gravity was mainly in the anteroposterior direction.
ABSTRACT
BACKGROUND:One-legged standing with eyes closed is a method to test the muscle strength and the ability of body balance, it is considered to be an important quality indicator for evaluation of adults and elderly balancing capability in our country. A lot of works have been done in many provinces and cities, but there is a lack of in-depth studies. OBJECTIVE:To review the research progress of one-legged standing with eyes closed, to analyze its problem used in the physical fitness test and to prospect the future direction of the related researches. METHODS:A computer-based search on CNKI database and Elsevier database was undertaken to identify the article of balance capacity. The key words were“eyes closed and single legged standing, balance ability, physical fitness test”. Total y articles were searched and checked primarily, and those meeting the criteria were looked up. RESULTS AND CONCLUSION:The standard of one-legged standing with eyes closed for the male is higher than that for the female. Some elderly just stand for a short time in the test, and thus it is difficult to distinguish the balance ability. Elderly balance is significantly lower than that in young people. The same test method for adults and elderly people is employed, but whether it is scientific or not should be further studied. Various indicators in the test of one-legged standing with eyes closed have low correlation. For the above reasons, further studies should be made before the test of one-legged standing with eyes closed becomes a valuable measurement of the balance ability in the national physique.
ABSTRACT
This study was aimed to observe the improvement of Qiju Runmu Tie (QRT) on experimental dry eye syndrome in rats. The fourth day after the bleomycin hydrochloride (8 g·mL-1) was injected into the intraorbital lacrimal gland (0.06 mL) and extraorbital lacrimal gland (0.12 mL), QRT of large, medium, and small dosage (0.276 g·mL-1, 0.138 g·mL-1, 0.069 g·mL-1) was applied on rat's eyes continuously for 10 days, once a day, 1 hour every time. Rats in the control group and model group were applied with a patch containing distilled water in the same operation. The tear secretions, time of tear film break-up and pathological changes of lacrimal gland were observed from the eleventh day to the thirteenth day after injection. The results showed that compared with the control group, bleomycin hydrochloride can induce atrophy of lacrimal gland, hyperplasia and decrease bubbly mucus in the acinar lumina, significant reduce of tear secretion, and significant shorten the time of tear film break-up. Compared with the model group, QRT can significantly increase the amount of tear secretion (P <0.05), extend the tear film break-up time (P < 0.01). And the medium dosage of QRT can obviously reduce lacrimal gland tissue injury. It was concluded that external application of QRT can improve symptoms of experi-mental dry eye syndrome in rats.
ABSTRACT
BACKGROUND: There was no uniform criterion for muscle force sense test of the sagittal plane of the ankle joint.OBJECTIVE: To explore the test-retest reliability of the ankle muscle force sense (MFS) under different target force.METHODS: The target force of the muscle was 25%, 50% and 75% maximal voluntary isometric contraction to measure MFS.Consistency degree of the repeated measures was evaluated by intra-class correlation (ICC) and standard error of measurement(SEM).RESULTS AND CONCLUSION: Interclass correlation coefficients of variable errors and absolute errors in MFS were more than0.75, and SEM of them were lower. ICCs of constant error of them were less than 0.75, and SEMs of them were greater. Thetest-retest reliability for variable errors and absolute errors of MFS was better when the target force was smaller.

Glycosylated hemoglobin was measured at the 16th weeks after STZ injection. Results: Glycemia, serum lipids, serum creatinine were higher at the 8th, 12th and 16th week compared with normal group. Serum creatinine was higher at the 12th and 16th week, and glycosylated hemoglobin was also highter than that of the normal group. Xiaokekang reduced these changes. Conclusion: Xiaokekang can reduce glycemia, serum lipids and protect renal function.
ABSTRACT
Thirty-four articles about the biomechanical characters of ankle joint dated between January 1989 and October 2007 weresearched in Medline and Elsevier SDOS databases to analyze and review the influential factors for dynamic characters of the anklejoint. The kinetics characters of the ankle joint include: The absolute value of the kinetics character of female is smaller than that ofthe male. However, there are few differences or even no differences between them for the relative value of the kinetics character. Thekinetics characters of the ankle joint become weak as the aging of adults. Foot length and instep height have great impact on thekinetics character of the ankle joint. The kinetics characters of the anklebone will change with its angular velocity. Thesuper-isometric concentric-eccentric contraction shows the best effect in strength training on the ankle joint. There are many factorsthat influence the dynamic characters of the ankle joint, and partial conclusions are still uncertain.
