Objective:To observe the clinical effect of electroacupuncture(EA)combined with exercise therapy on balance function in patients with knee osteoarthritis(KOA). Methods:Seventy patients with KOA were randomly divided into a treatment group and a control group,with 35 cases in each group.The treatment group was treated with EA combined with exercise therapy.EA was applied to Dubi(ST35),Neixiyan(EX-LE4),Xuehai(SP10),Liangqiu(ST34),Yanglingquan(GB34),and Zusanli(ST 36).Exercise therapy(muscle strength training and knee mobility training)was applied after EA.The control group only received the same exercise therapy as the treatment group.The two groups were treated with the same course of treatment,3 times a week for 4 consecutive weeks,12 times in total,and followed up for 1 month.The Pro-Kin254P balance test system was used to measure the balance function parameters at 4 time points,including before treatment,after 1 session of treatment,after 12 sessions of treatment,and at 1-month follow-up after treatment.The visual analog scale(VAS)and the Western Ontario and McMaster Universities osteoarthritis index(WOMAC)scores were recorded. Results:The markedly effective rate and total effective rate in the treatment group were higher than those in the control group(P<0.01).The Romberg area,Romberg length,and VAS scores of the two groups decreased significantly after 1 session of treatment,12 sessions of treatment,and 1 month after treatment,and the differences between different time points in the same group were statistically significant(P<0.01).There were significant differences between the two groups at the same time point(P<0.05).The total WOMAC scores of the two groups after 1 session of treatment,12 sessions of treatment,and 1 month after treatment decreased significantly,and there were significant differences between different time points in the same group(P<0.05),but there was no significant difference between the two groups at the same time point(P>0.05). Conclusion:EA combined with exercise therapy or exercise therapy alone can enhance the balance function,relieve joint pain,and improve joint function in patients with KOA.EA combined with exercise therapy is superior to exercise therapy alone in improving balance function and pain,but the two treatment protocols have similar effects in improving joint function.

BACKGROUNDInfections caused by gram-negative bacteria (GNB) often lead to high mortality in common clinical settings. The effect of traditional antibiotic therapy is hindered by drug-resistant bacteria and unneutralizable endotoxin. Few effective methods can protect high risk patients from bacterial infection. This study explored the protection of adeno-associated virus 2 (AAV2)-bacteriacidal permeability increasing protein 700 (BPI(700))-fragment crystallizable gamma one 700 (Fc gamma1(700)) chimeric gene transferred mice against the minimal lethal dose (MLD) of E. coli and application of gene therapy for bacterial infection.

METHODSAfter AAV2-BPI(700)-Fc gamma1(700) virus transfection, dot blotting and Western blotting were used to detect the target gene products in Chinese hamster ovary-K1 cells (CHO-K1cells). Reverse transcription-polymerase chain reaction and immunohistochemical assay were carried out to show the target gene expression in mice. Modified BPI-enzyme linked immunosorbent assay was used to identify the target gene products in murine serum. The protection of BPI(700)-Fc gamma1(700) gene transferred mice was examined by survival rate after MLD E. coli challenge. Colony forming unit (CFU) count, limulus amebocyte lysate kit and cytokine kit were used to quantify the bacteria, the level of endotoxin, and proinflammatory cytokine.

RESULTSBPI(1-199)-Fc gamma1 protein was identified in the CHO-K1 cell culture supernatant, injected muscles and serum of the gene transferred mice. After MLD E. coli challenge, the survival rate of AAV2-BPI(700)-Fc gamma1(700) gene transferred mice (36.7%) was significantly higher than that of AAV2-enhanced green fluorescent protein (AAV2-EGFP) gene transferred mice (3.3%) and PBS control mice (5.6%). The survival rate of AAV2-BPI(700)-Fc gamma1(700) gene transferred mice treated with cefuroxime sodium was 65.0%. The bacterium number in main viscera, the levels of endotoxin and proinflammatory cytokine (tumor necrosis factor-alpha and interleukin-1beta) in serum of the AAV2-BPI(700)-Fc gamma1(700) gene transferred mice were markedly lower than that of PBS control mice (P < 0.01).

CONCLUSIONSAAV2-BPI(700)-Fc gamma1(700) gene transferred mice can resist MLD E. coli infection through expressing BPI(1-199)-Fc gamma1 protein. Our findings suggested that AAV2 mediated BPI(700)-Fc gamma1(700) gene delivery could be used for protection and treatment of clinical GNB infection in high-risk individuals.

The compatibility of Chinese medicine and western medicine is becoming more and more common,but the changes in efficacy and adverse reactions of drug interaction caused by drug interaction has attracted more and more attentions.This article mainly expounds the interaction between Chinese medicine and western medicine in four aspects:absorption,distribution,metabolism and excretion of drugs.Among them,Chinese medicine can affect western medicine absorption by changing the gastrointestinal pH,gastrointestinal motility and gastric emptying time changes,the chelate complexes,and the precipitate formation;it can change the distribution of the main active ingredients in western medicine;it can change liver microsomal enzyme and non-microsomal enzyme to affect western medicine metabolism,the western medicine excretion through the bile and kidney,and western medicine transport process in vivo by P-glycoprotein.The article explains the pros and cons of Chinese medicine and western medicine from the pharmacokinetic process,which provides the basis for the clinical guidance for the combination therapy of Chinese medicine and western medicine.

OBJECTIVE To study the effects of Liuweidihuang Formula (LWDHF) on the ovariectomized ApoE-/-AS mice and the proliferation and migration of vascular smooth muscle cell (VSMCs) in vitro,and to elucidate the roles of estrogen receptor β (ERβ) and heat shock protein 27 (HSP27) phosphorylation in the context.METHODS The artery injury of ApoE /-mice was observed by HE staining and the phosphorylation of HSP27 in vessels was detected by immunohistochemistry.VSMC proliferation and cell cycle were examined by MTT assay and flow cytometry,respectively.VSMC migration was observed by wound-healing assay and F-actin staining.The levels of HSP27,pHSP27,cyclin D1,protein phosphatase 2 (PP2A) and ERβ were determined by Western blot analyses.Transfection with ERβ siRNA and ERα shRNA was carried out to investigate their roles in LWDHF effects,respectively.RESULTS LWDHF improved the arterial lesion,inhibited HSP27 phosphorylation,and increased the expression of PP2A and ERβ in ovariectomized ApoE / AS mice.In in vitro experiments,angiotensin Ⅱ (Ang Ⅱ) at 1 × 10-7 mol/L obviously induced VSMC proliferation and migration,increased the expression of cyclin D1 and cell number in the S phase,but these effects were significantly inhibited by LWDHF (12μg/mL).Further molecular examinations showed that LWDHF up-regulated PP2A expression through ERβ to inhibit HSP27 phosphorylation,contrib uting to inhibition of VSMC proliferation and migration.CONCLUSION LWDHF reduced menopause AS in vivo and inhibited proliferation and migration of VSMCs by regulating ERβ-inhibition of HSP27 phosphorylation in vitro.These discoveries provided novel molecular insights into LWDHF as potential therapy for AS.

Objective To investigate the effectiveness and safety of rosuvastatin and simvastatin in the treatment of hyperlipidemia. Methods The database including CNKI, VIP, Wanfang data base and CBM were retrieved to search the clinical randomized controlled trials (RCT) of rosuvastatin and simvastatin in the treatment of hyperlipidemia, and the data were analyzed with Review Manager 5.2. Results Eighteen RCTs were included with a total sample size of 1819 cases with hyperlipidemia, in which there were 917 patients in rosuvastatin group and 902 in simvastatin group. The Meta-analysis results showed that there were significantly lower serum levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), triglyceride (TG) and significantly higher level of high-density lipoprotein cholesterol (HDL-C) in rosuvastatin group compared with those of simvastatin group [(MD=-0.15, 95%CI:-0.22--0.09, P<0.01), (MD=-0.18, 95%CI:-0.25--0.11, P<0.01), (MD=-0.23, 95%CI:-0.28--0.19, P<0.01) and (MD=-0.11, 95%CI:-0.06--0.15, P<0.01)]. There was no significant difference in the incidence of gastrointestinal adverse reaction between the two groups. Conclusion The current clinical evidences show that rosuvastatin has a better effect on the treatment of hyperlipidemia, and has no adverse reactions.

Objective To explore the feasibility of the adjustable brace asymmetric tethering in concave side for establishing a porcine scoliosis model.Methods Six minority piglets (aged 8-10-week-old, weight 8-10 kg) were selected and the adjustable brace asymmetric tethering in concave side were applied during the procedure.Roentgenography was performed before and immediately after the operation, and 1, 2 and 3 months after the procedure.Cobb angles were measured based in the plain radiograph.Results A piglet died for narcotic drug overdose and the other 5 pigs succeeded in modeling.The cobb angles were (9.0 ±1.6) ° in one month, (11.8 ±1.3) ° in two months and (21.6 ±2.4) ° in three months after the operation . Conclusion It's is an effective way to establish the porcine model of rapidly progressive structural scoliosis by the adjustable brace asymmetric tethering in concave side.It avoids the damage to the spinal elements and could be an ideal model for further study on corrective techniques.

Objective To evaluate the value of third-generation dual-source CT scanner in application of high-pitch aorta CT angiography(CTA). Methods Totally 59 patients clinically indicated for whole aorta angiography were divided into 2 groups using a simple random method:in group 1 there were 28 patients who underwent the examination on a third-generation dual-source CT device,with a collimation of 2×192×0.6 mm and a rotation time of 0.25 s;in group 2 there were 31 patients who underwent the examination on a second generation dual-source CT device,with a collimation of 2×128×0.6 mm and a rotation time of 0.28 s. Both groups were given the examination operated in dual-source high-pitch ECG-gating mode with a pitch of 3.0,a tube voltage of 100 kV,and automated tube current modulation using a reference tube current of 288 mA. A contrast material bolus of 45 ml with a flow of 4.5 ml/s followed by a 50 ml saline chaser in 5.0 ml/s was used. CTA scan was automatically started using a bolus tracking technique at the level of the original part of aorta after a trigger threshold of 100 HU was reached. The start delay was set to 6 s in both groups. Effective dose(ED),signal to noise ratio (SNR),contrast to noise ratio (CNR),and subjective diagnostic quality of both groups were evaluated. Results The mean ED were 19.44% lower (t=-3.989,P=0.000) in group 1 [(3.15±0.86)mSv] than in group 2 [(3.91±0.60)mSv]. These two groups showed no significant differences in SNR or CNR (all P >0.05). The subjective diagnostic quality values also showed no significant difference between two groups [(1.39±0.50)scores vs. (1.45±0.51)scores;W=814.5,P=0.651].Conclusion Compared with the second-generation dual-source CT scanner,the third-generation dual-source CT scanner in whole aorta CTA can remarkably reduce the radiation dose without affecting image quality.

Objective To evaluate the application of automated tube potential selection technique in high-pitch dual-source CT aortic angiography on a third-generation dual-source CT scanner. Methods Whole aorta angiography were indiated in 59 patients,who were divided into 2 groups using a simple random method:in group 1 there were 31 patients who underwent the examination with automated tube potential selection using a vascular setting with a preferred image quality of 288 mA/100 kV;in group 2 there were 28 patients who underwent the examination with a tube voltage of 100 kV and automated tube current modulation using a reference tube current of 288 mA. Both groups were scanned on a third generation dual-source CT device operated in dual-source high-pitch ECG-gating mode with a pitch of 3.0,collimation of 2×192×0.6 mm,and a rotation time of 0.25 s. Iterative reconstruction algorithm was used. For group 1,the volume and flow of contrast medium and chasing saline were adapted to the tube voltage. For group 2,a contrast material bolus of 45 ml with a flow of 4.5 ml/s followed by a 50 ml saline chaser at 5 ml/s was used. CTA scan was automatically started using a bolus tracking technique at the level of the original part of aorta after a trigger threshold of 100 HU was reached. The start delay was set to 6 s in both groups. Effective dose (ED),signal to noise ratio (SNR),contrast to noise ratio (CNR),and subjective diagnostic quality of both groups were evaluated. Results The mean ED were 21.3% lower (t=-3.099,P=0.000) in group 1 [(2.48±0.80) mSv] than in group 2 [(3.15±0.86) mSv]. Two groups showed no significant difference in attenuation,SD,SNR,or CNR at all evaluational parts of aorta (ascending aorta,aortic arch,diaphragmatic aorta,or iliac bifurcation)(all P>0.05). There was no significant difference in subjective diagnostic quality values of two groups [(1.41±0.50) scores vs. (1.39±0.50) scores;W=828.5,P=0.837]. Conclusion Compared with automated tube current modulation,the automated tube potential selection technique in aorta CT angiography on a third-generation dual-source CT can dramatically reduce radiation dose without affecting image quality.
