Objective:To explore the essence of Radix Morindae Officinalis in strengthening bones through observing the effect of medicated serum of Radix Morindae Officinalis on cultured osteoblast in vitro. Methods:The medicated serum of Radix Morindae Officinalis was added to the osteoblasts which were separated from the cranium of 24-hours newborn SD rat,in order to determining the effect of TGF-?1 and the proliferation and secreting of alkaline phosphatase and osteocalcin of the osteoblasts. Results:The proliferation of the osteoblasts were signifi cantly stimulated by the alcohol and the n-butanol extract from the Radix Morindae Officinalis; and the n-butanol extract from the Radix Morindae Officinalis could promote differentiating OB excreting the ALP and OC;in addition,the ability of the osteoblasts expressing TGF-?1 was promoted by the n-butanol extract from the Radix Morindae Officinalis. Conclusion:The n-butanol extract from the Radix Morindae Officinalis can promote the ability of the osteoblast in expressing TGF-?1 mRNA and excreting the ALP,and further promote the growth of bone.

Objective To investigate the effects of orphanin FQ (OFQ) on simple and norepinephrineactivated cardiac function in isolated rat heart.Methods Male SD rats aged 3-4 months weighing 250-280 g were anesthetized with intraperitoneal 25% urethane 1.4-1.8 ml.Their hearts were excised and passively perfused with K-H solutionin a Lanngendorff apparatus.A fluid-filled latex balloon was inserted into left ventricle for measurement of developed pressure.Left ventricular systolic pressure(LVSP),left ventricular end-diastofic pressure(LVEDP),left ventricular developed pressure(LVDP=LVSP-LVEDP),HR and±dp/dtmax were measured.Sixty isolated rat hearts were randomly divided into 10 groups(n=6 each):Ⅰ control group (group C);Ⅱ,Ⅲ,Ⅳ OFQ1,OFQ2,OFQ3 group--OFQ 10-6,10-7,10-8 mol/L were administered via perfusion system respectively;Ⅴ OFQ+UFP group--OFQ 10-6 mol/L+UFP-101 (all OFQ antagonist) 10-6 mol/L were administered;Ⅵ NE group--norepinephrine 10-5 mol/L;Ⅶ,Ⅷ,Ⅸ NE+OFQ groups--NE 10-5 mol/L+OFQ 10-6,10-7,10-8 mol/L were administered respectively;Ⅹ NE+OFQ+UFP group--NE 10-5 mol/L+OFQ 10-6mol/L+UFP-101 10-6mol/L.Results LVSP,LVDP and±dp/dtmax were significantly increased while HR was significantly decreased in the 3 OFQ groups as compared with control group.LVSP,LVDP±dp/dt max and HR were significantly increased in the 3 NE+OFQ groups as compared with NE group.Conclusion OFQ has positive inotropic action and negative chronotropic effect on the isolated rat heart.OFQ Can enhance the positive inotropic and chronotropic effect of NE on the heart.

Objective To find the optimal stimulation parameters of electroacupuncture for incision pain and visceral dragging pain after surgery.Method Databases including the China National Knowledge Infrastructure (CNKI), WanFang (WF), VIP and PubMed were retrieved by using computer. The eligible literatures related to the clinical and experimental studies on electroacupuncture for post-operative pain were summarized and the frequencies of the involved electroacupuncture parameters were counted.Result For incision pain, electroacupuncture was used after surgery, with continuous wave, usually a low frequency ranged 2~15 Hz and a current of 2~5 mA; for visceral dragging pain, electroacupuncture was used before surgery, with sparse-intense wave, alternate frequencies majorly at 2/100 Hz and a medium or low current intensity within patient’s endurance. Conclusion In clinical application, the elctroacupuncture parameters should be chosen carefully according to the type of post-operative pain.

Objective To evaluate the clinical applicational value of color doppler flow image(CDFI)to perforation of ventricular septum resulting from myocardial infarct.Methods Before 7 cases confirmed perforation of ventricular septum though DSA,were examined by CDFI.The two results were compared to study the difference of bothes.Results All patients' results though CDFI were as the same as those though DSA,and accuracy rating was 100%.Conclusion CDFI may be applicated to early diagnose perforation of ventricular septum.

· AIM: To investigate the complications of intravitreal triamsinolone acetonide (TA) injection in vitrectomy for proliferative diabetic retinopathy (PDR).· METHODS: From February 2005 to January 2007, 18patients (18 eyes) with PDR who were injected with TA in vitrectomy were observed retrospectively after surgery.· RESULTS: During a postoperative follow-up period of 3 to 6 months (mean 4.6 months), some complications including deposit of TA granules on the macular region and surface of the retina (3 eyes), postoperative vitreous hemorrhage (3eyes), elevated intraocular pressure (2 eyes) and pseudohypopyon (1 eye)were observed.· CONCLUSION: The complications after surgery such as deposit of TA granules on the macular region and surface of the retina and pseudohypopyon could be cured without any special treatment. All eyes with elevated intraocular pressure after surgery were controlled by drug. Re-operation may be an effective method for patients with unabsorbable vitreous hemorrhage after vitrectomy.

The big-data era has arrived, which involves all professions and trades. Its impact on the medical field has gradually revealed. With the characteristics of big data "4V" (volume, velocity, variety, value) and its theory generality with TCM (holistic thinking, correlativity) as well as regularity of disease development, combined with present status of acupuncture clinical research, the influences of big-data era on trial design, data collection, analysis and sharing of acupuncture clinical research are discussed in this paper, aiming to provide references for solving the difficulties of study design and determining the future research direction of acupuncture clinical research.

Mitochondrial dysfunction plays an important role in the process of PD, DJ-1 participates in regulating the function of mitochondria,which has an effect on the protection of mitochon-dria. DJ-1 mutations can lead to the decrease of the activity of mitochondrial complex Ⅰ, the decrease of mitochondrial mem-brane potential and then mitochondrial fragmention and mitoph-agy, and then further damage neurons and trigger PD. This re-view presents the role of DJ-1 in regulating the function of the mitochondria in the pathogenesis of Parkinson's disease(PD).

Objective To investigate the effect of costimulatory molecules 4-1BB/4-1BBL on T cell activation with systemic lupus erythematosus(SLE)patients.Methods The expression of NF-kB mRNA and p38 MAPK mRNA of T cells with 20 SLE patients and 20 normal controls before activation,after activation and blocked bv 4-1BB/4-1BBL were detected bv RT-PCR.The protein levels of p-p38 MAPK and NF-kB were detected by Western blot.Results The expression of NF-kB mRNA and p38 MAPK mRNA and the protein expression of NF-kB and p-p38 MAPK of T cell with SLE patients were higher than that of normal controls(P＜0.01).There were more expression of NF-kB mRNA,p38 MAPK mRNA,NF-kB protein and p-p38 MAPK protein of T cell with SLE patients stimulated by anti-CD3 monoantibody(P＜0.01).In anti-4-1BB monoantibody blockage group,there were decreased expression of p38 MAPK mRNA and p-p38 MAPK protein(P＜0.01).but not the decreased NF-kB mRNA and protein expression.Conclusion Costimulatory molecule 4-1BB plays a critical role in T cell activation of SLE by p38 MAPK signal pathway.
