[Objective] To investigate the effect of Dengzhan Xixin Injection (DXI) combined with photon-autotransfusion therapy in treating diabetic peripheral neuropathy (DPN). [ Methods ] Sixty-one cases of DPN were randomized into 2 groups. Group A ( n=31) was given DXI 30 - 40 mL (intravenous drip, qd) and photon-autotransfusion therapy (once every 2-3 days). Group B (n = 30) was treated with anisodamine 10 - 20 mg (intravenous drip, qd) and vitamin B] 100 mg and B12 500 ?g (intramuscular injection, qd) . Changes of symptoms and signs and neural conductive velocity were observed to evaluate the curative effect after treatment. [ Results ] The markedly effective rate and total effective rate were 58.07% and 93.55% respectively in group A, which were higher than those in group B (16.67% and 63.34% respectively) , the difference being significant ( P

Objective To observe the effects of angiotensin Ⅱ(AngⅡ) AT 1 receptor antagonist,valsartan and mineralocorticoid receptor antagonist,spironolactone on growth factors and type Ⅰ collagen in aorta in spontaneously hypertensive rat(SHR).Methods Six-week male SHRs were divided into three groups at random:SHR control group,valsartan group and spironolactone group;six homogenous Wistar Kyoto(WKY) rats was served as normal control group.Valsartan 30mg?kg -1 ?d -1 ,spironolactone 20mg?kg -1 ?d -1 were respectively administered to rats in valsartan group and spironolactone group.Expressions of transforming growth factor ? 1(TGF ? 1),hepatocyte growth factor(HGF) and type Ⅰ collagen gene mRNA in aorta were determined by RT-PCR.Results Compared with those of untreated SHR group,levels of TGF?1 and type Ⅰ collagen gene mRNA expression in aortas treated with valsartan and spironolactone for 13 weeks were significantly reduced(P

Objective To investigate the effect of cetuximab (C225) combined with radiation on the expressions of Ku80 and ATM in CNE-2 nude mice xenograft tumor model.Methods The CNE2 nude mice xenograft tumor model was established and divided into control group,conventional radiotherapy (CRT) group,simulated intensity modulated radiation therapy (sIMRT) group,C225 group,CRT + C225 group and sIMRT + C225 group with 8 mice in each group.The dose of radiation was 20 Gy,and 1mg C225 per mice in abdominal cavity was applied for the drug treatment.The transcriptional levels of Ku80 and ATM were assayed by RT-PCR and Western blot.Results Compared with control group,the transcriptional and translational levels of Ku80 and ATM in CRT group,sIMRT group,CRT + C225 group and slMRT + C225 group were decreased (P ＜ 0.05).Compared with CRT group,the down-regulation of transcriptional and translational ATM level in sIMRT group was obvious (P ＜ 0.05),and further strengthened in the CRT + C225 group and sIMRT + C225 groups (P ＜0.05),but there was no significant difference of ATM expression between sIMRT + C225 group and CRT group (P ＞ 0.05).Conclusions C225 alone can restrain the transcriptional and translational level of ATM,and the transcriptional and translational level of Ku80 and ATM are also restrained after megadose.ATM is down-regulated by sIMRT but up-regulated by the combination of C225 and radiation.

Objective To provide the scientific evidence for studying Alzheimer's disease (AD) and decision-making for its management by analyzing the strategic information of hotspots in studies on AD.Methods Citation strategic coordinate diagram was plotted by describing the history of studies on AD with co-citation clustering for further understanding the novelty and concern of hotspots in studies on AD.The current hotspots in studies on AD were discovered by co-words clustering and their strategic coordinates were analyzed to reveal their development periods.Results The current hotspots in studies on AD were substance metabolism in AD patients, etiology of AD and therapies for AD.The diagnosis of AD according to its clinical characteristics and hypothesis on amyloid cascade in AD patients were greatly concerned.Conclusion Citation strategic coordinate analysis and co-words strategic coordinate analysis can display the hotspots in studies on AD and their development history.

OBJECTIVE:To explore the spasmolytic effect of baked Radix Vladimiriae on in vitro intestinal muscle in rabbits. METHODS:Magnus in vitro intestinal muscle accumulative dose method was adopted to observe the dose-effect relationship of petroleum ether parts of baked Radix Vladimiriae with in vitro intestinal muscle of rabbits and its impact on the spasm of rabbit intestinal muscle induced by acetylcholine, histamine phosphate and Bacl2. RESULTS:There was a certain dose-effect relationship between petroleum ether parts of baked Radix Vladimiriae and spasmolytic mechanism of rabbit in vitro intestine. It showed the effect of acetylcholine, histamine phosphate and Bacl2. CONCLUSION:The inhibition effect of petroleum ether parts of baked Radix Vladimiriae on normal in vitro intestinal muscle increase as long as dose increase. The inhibition mechanism may be associated with acetylcholine competing with histamine to block M receptor and H1 receptor as well as to inhibit excitability of intestinal muscle.

Objective To explore the inhibiting effect of valsartan and spironolactone on cardiac fibrosis and the expression of integrin ? 1 and fibronectin in the heart of spontaneously hypertensive rats. Methods Eighteen 6 week old SHR were randomly divided into 3 groups with 6 in each: SHR control group, valsartan treating group(30 mg?kg -1 ?d -1 ) and spironolactone treating group ( 20 mg?kg -1 ?d -1 ). Six homogenous male WKY rats served as normal group. After 14 weeks of treatment, systolic blood pressure, left ventricular mass, the ratio of left ventricular mass to body weight (LVM/BW), collagen volume fraction(CVF) and perivascular collagen area(PVCA) were determined and compared among these groups. The expression of integrin ? 1 and fibronectin were also examined by immunohistochemical method. Results Compared with the untreated SHR S, systolic blood pressure was significantly decreased in both treatment groups. LVM/BW〔(2 84?0 14)?10 -3 vs(3 22?0 15)?10 -3 〕, CVF〔(3 21?0 22)%vs(4 00?0 28)%〕, PVCA〔(0 62?0 15)%vs(0 94?0 56)%〕 were lower in both treatment groups, these parameters in SHR V group were even lower than those in SHR S group. Compared with the untreated SHR S, the expression of integrin ? 1 was significantly reduced in SHR V group, while the expression of fibronectin was markedly reduced in both treatment groups. Conclusions Both valsartan and spironolactone could control blood pressure, and effectively inhibit the cardiac fibrosis. Valsartan could also inhibit the expression of cardiac integrin ? 1 and fibronectin, which might be the reason that valsartan is better than spironolactone in inhibiting cardiac fibrosis.

ObjectiveTo investigate the association of hypertensive target organ damage with abnormal ankle brachial index (ABI) in high-risk hypertensive patients.MethodsDuring December 2008 to May 2009,a cross-sectional study was conducted to investigated the prevalence of abnormal ABI (ABI ＜ 0.90) in 2674 community-dwelling,hypertensive patients,who aged ＞ 40 years,without coronary heart disease,stroke/transient ischemic attack or known arteriosclerosis,from 18 centers in China. Data were acquired through history,physical examination,laboratory and other diagnostic tests.ResultsThere were 2615 subjects eligible for the full analysis set. The high-risk hypertensive patients with arterial wall thickening,arterial wall thickening and slightly elevated serum creatinine had a higher prevalence of abnormal ABI than their counterparts respectively ( P ＜ 0.05 ). Compared with the normal group,the abnormal ABI group had a higher serum creatinine level on average (P ＜ 0.01 ).After adjustment for certain factors including investigation center,demographic factors,cardiovascular disease (CVD) risk and CVD risk factors using an unconditional logistic regression model,arterial wall thickening ( OR 2.416,95％ CI 1.395-4.183,P =0.0016 ) and slightly elevated serum creatinine ( OR 3.377,95％ CI 1.267-8.997,P =0.0149) were positively associated with abnormal ABI. However,arterial wall thickening (OR 0.988,95％ CI 0.576-1.695,P=0.9664) and microalbuminuria (OR 1.389,95％ CI0.685-2.817,P=0.3621)were irrelevant to abnormal ABI.Conclusions So far as a high-risk hypertensive patient is concerned,there are significant statistical correlations between arterial wall thickening and/or slightly elevated serum creatinine and an abnormal ABI,but no significant statistical correlations between arterial wall thickening or microalbuminuria and an abnormal ABI is observed.
