However, there remains an argument as to their importance in the onset of AD.Recent studies have shown that axonopathy is considered as an early stage of AD. However, the exact relationship between axonopathy and the origin and development of classic neuropathological changes such as senile plaques （SPs） and neurofibrillary tangles （NFTs） is unclear. The present study aimed to investigate this relationship. Methods Postmortem tracing, combined with the immunohistochemical or immunofluo-rescence staining, was used to detect axonopathy and the formation of SPs and NFTs. Results ＂Axonal leakage＂–a novel type of axonopathy, was usually accompanied with the extensive swollen axons and varicosities, and was associated with the origin and development of Aβ plaques and hyperphosphorylated tau in the brains of AD patients. Conclusion Axonopathy, particularly axonal leakage, might be a key event in the initiation of the neuropathological processes in AD.展开更多

METHODS:A total of 57 patients with previously untreated anisometropic amblyopia without strabismus(range:8-35 years),were measured refractive error,best corrected visual acuity(BCVA),fusion and stereopsis,and 48 patients have completed contrast sensitivity function test.AM was determined by dioptric vector addition model,and the amblyopia depth was determined by the difference of BCVA in logMAR units between the amblyopic and fellow eyes.RESULTS:AM was significantly correlated with both amblyopia depth(Pearson R=0.728,P【0.001) and the inter-ocular difference of the area under the log contrast sensitivity function(AULCSF)(R=0.505,P【0.001).Depth of amblyopia and the inter-ocular difference of AULCSF was also significantly correlated(R=0.761,P【0.001).The more severity of amblyopia,the poorer levels of contrast sensitivity.Most pure anisometropes with AM was less than 3.0D retain fusion and some stereopsis,but when AM were more than 3.0D,especially for the anisometropes whose AM was more than 6.0D,fusion and stereopsis function were seriously impaired.CONCLUSION:In the patients with previously untreated anisometropic amblyopia,higher degree of anisometropia is significantly associated with deeper amblyopia,worse contrast sensitivity,fusion and stereopsis functions.展开更多

Results show that the health-preserving moxibustion has an evident action in lessening aging symptoms and improving physio-logic functions of the senile body. It is held in traditional Chinese medicine that from the middle-aged period on, the decline of kidney Qi is an important cause of senility and deficiency of thespleen and blood stasis also play a role in some degree. Health-preserving moxibustion ofShenque and Zusanli has actions in warming Yang, reinforcing Qi and promoting blood circulationto remove obstruction in meridians. It is thus a method for self health protection.展开更多

文摘AIM:To assess the quantitative association between anisometropia magnitude(AM) and the losses of resolution and contrast sensitivity;and to exemplify how the function of fusion and stereopsis vary with AM in previously untreated anisometropic amblyopia. METHODS:A total of 57 patients with previously untreated anisometropic amblyopia without strabismus(range:8-35 years),were measured refractive error,best corrected visual acuity(BCVA),fusion and stereopsis,and 48 patients have completed contrast sensitivity function test.AM was determined by dioptric vector addition model,and the amblyopia depth was determined by the difference of BCVA in logMAR units between the amblyopic and fellow eyes.RESULTS:AM was significantly correlated with both amblyopia depth(Pearson R=0.728,P【0.001) and the inter-ocular difference of the area under the log contrast sensitivity function(AULCSF)(R=0.505,P【0.001).Depth of amblyopia and the inter-ocular difference of AULCSF was also significantly correlated(R=0.761,P【0.001).The more severity of amblyopia,the poorer levels of contrast sensitivity.Most pure anisometropes with AM was less than 3.0D retain fusion and some stereopsis,but when AM were more than 3.0D,especially for the anisometropes whose AM was more than 6.0D,fusion and stereopsis function were seriously impaired.CONCLUSION:In the patients with previously untreated anisometropic amblyopia,higher degree of anisometropia is significantly associated with deeper amblyopia,worse contrast sensitivity,fusion and stereopsis functions.
文摘Objective To compare the therapeutic effect differences of senile osteoarthritis treated by the combined therapy of acupuncture and Chinese medicine and western medication.Methods Eightytwo cases of senile osteoarthritis were randomly divided into 2 groups.In observation group（42 cases）,puncture at Shènshū （肾俞 BL 23）,Yāoyángguān （腰阳关 GV 3）,Fēngchí（风池 GB 20） and Dàzhuī（大 椎 GV 14） etc.combining with Chinese medicine of Bushen Zhuanggu Decoction for oral administration was applied;in control group （40 cases）,routine western medicine was applied.Pain score and theraputic effect of both groups were observed before and after treatment.Results The total effective rate was 88.1%（37/42） in observation group,and 60.0%（24/40） in control group.The therapeutic effect in observation group was superior to that in control group （P0.01）.The pain score was improved by both therapies （P0.05,P0.01） after treatment,and the improvement in observation group was superior to that in control group （P0.05）.Conclusion The therapeutic effect of senile osteoarthritis by combined therapy of both acupuncture and Bushen Zhuanggu Decoction for oral administration is superior to that by western medication.
文摘The purpose of this study is to determine whether advancing age andheart failure are independent predictors of increased mortality afrer acutemyocardial infarction(AMI)We reviewed the clinical data of 1068 in-patients(344 senile/724 nonsenile)with AMI.The results showed atypicalpresentations of infarction-related symptoms in the elderly are common,with consequent delay in the diagnosis and treatment The elderly patientshad a high proportion of systemic hypertension(43.9%),non Q wave AM/(36%)and heart failure(35.5%),On the contrast,the proportion of that innonsenile patients were 33%,8Vo and 16.4% respectively.In elderlypatients,several complications:of AMI are more common,asinterventricular septum perforation(2%),cardiogenic shock(19.8%),arthythmia(61.9%).Heart failure was more frequent in patients with leftventricular ejection fraction(LVEF)≤35%,previous heart failure ormyocardial infarction,and anterior location infarction.Those with severecongestive heart failure had a mortality of 33.2% compared with 24.5% forthose with moderate heart failure and 13.51% for those with no heart failurein the first eight weeks.The following factors were associated with anincreased risk of death:older age,longer delay before admission to hospital,no prescription of beta-blaekers and a previous history of infarctionOur data suggested that the prognosis after AMI was directly related toadvaneeing age and the severity of congestive heart failure.Thedevelopment of congestive heart failure was an independent predictor ofdeath.The increasing incidence and mortality were closely related toimpaired myocardial reserve.The present benefits,as pointed out by therecent progress in AMI therapy,must be employed in the treatment of olderinfarcted patients More aggressive management in elderly patients shouldoe evaluated for its potential to reduce mortality.
文摘The present paper reports a clinical observation of the effect of health-preservingmoxibustion in the aged people without apparent organic diseases. Results show that the health-preserving moxibustion has an evident action in lessening aging symptoms and improving physio-logic functions of the senile body. It is held in traditional Chinese medicine that from the middle-aged period on, the decline of kidney Qi is an important cause of senility and deficiency of thespleen and blood stasis also play a role in some degree. Health-preserving moxibustion ofShenque and Zusanli has actions in warming Yang, reinforcing Qi and promoting blood circulationto remove obstruction in meridians. It is thus a method for self health protection.

文摘BACKGROUND Constipation is one of the chronic gastrointestinal functional diseases.It seriously affects the quality of life.Cistanche deserticola(C.deserticola)can treat constipation obviously,but its mechanism has not been clarified.We supposed that mechanism of it improved the intestinal motility by stimulating interstitial Cajal cells(ICC).Activation of the C-kit receptor on the surface of ICC is closely related to ICC function,and the stem cell factor(SCF)/C-kit signaling pathways plays an important role on it.To investigate the mechanism of how C.deserticola treats constipation,this study aimed to establish a constipation model in rats and explore the role of SCF/C-kit signaling pathway in the treatment.AIM To explore the SCF/C-kit signaling pathways in the role of C.deserticola for treatment of constipation by a constipation rat model.METHODS Forty-eight 8-mo-old Sprague–Dawley rats were divided into 4 groups by random weight method:Normal group(n=12),model group(n=12),C.deserticola group(n=12)and blocker group(n=12).The normal group received normal saline by gavage;the model group received loperamide by gavage;the blocker group received loperamide and C.deserticola by gavage,and STI571 was injected by intraperitoneally.During treatment,the weight,fecal granules and fecal quality were recorded every 10 d.On day 20 after model induction,the colon tissues of each group were removed.Hematoxylin and eosin staining was used to observe pathological changes.Expression levels of SCF,C-kit and Aquaporin genes were detected by immunohistochemistry,western blotting,and real-time-quantitative polymerase chain reaction.The colonic epithelial mitochondria and goblet cells were observed by transmission electron microscopy.RESULTS Compared with the normal group,as treatment progressed,the weight of rats in the model and blocker groups decreased significantly,the stool weight decreased,and the stool quality was dry(P<0.05).C.deserticola reversed the decrease in body weight and stool weight and improved stool quality.Histopathological analysis indicated that the colonic mucosal epithelium in the model group was incomplete,and the arrangement of the glands was irregular or damaged.Treatment with C.deserticola improved the integrity and continuity of the epithelial cells and regular arrangement of the glands.The blocking agents inhibited the effects of C.deserticola Immunohistochemistry and real-timequantitative polymerase chain reaction showed that expression of SCF and C-kit protein or genes in the colonic tissue of the model group was decreased(P<0.05),while treatment with C.deserticola increased protein or gene expression(P<0.05).Western blotting showed that expression of aquaporin APQ3 was increased,while the expression of Cx43 decreased in the model group.Treatment with C.deserticola inhibited expression of APQ3 and promoted expression of Cx43.Transmission electron microscopy showed that the mitochondria of the colonic epithelium in the model group were swollen and arranged disorderly,and microvilli were sparse.The condition was better in the C.deserticola group.Mice treated with STI571 blocker confirmed that blocking the SCF/C-kit pathway inhibited the improvement of constipation by C.deserticola.CONCLUSION C.deserticola improved defecation in rats with constipation,and the SCF/C-kit signaling pathway,which is a key link of ICC function,played an important role of the treatment.
