BACKGROUND: Although considerable progress has been made in spinal tuberculosis surgery,considering the particularity of the spine position, the surgical treatment is limited by the body stress and secondary injury due to removal of the internal fixation. Tissue engineering provides a new insight into the treatment of various diseases.Ideal biomaterials instead of traditional internal fixation materials are characterized by non-toxic and non-immune rejections.OBJECTIVE: To explore the biocompatibility and mechanical properties of alginate combined with bone marrow mesenchymal stem cells for repair of spinal tuberculosis.METHODS: Forty New Zealand rabbits were divided into four groups, 10 rats in each group: control group, spinal tuberculosis group, alginate group and titanium alloy group. The control group received no treatment, and in the other groups, boreholes were drilled in the fifth lumbar intervertebral disc and filled with gelatin sponge, and Mycobacterium tuberculosis suspension 0.1 mL (the amount of bacteria, 5 g/L)was then injected to make spinal tuberculosis models.Two months after modeling, simulated L4-5 spinal tuberculosis surgery was performed in the latter two groups, and alginate combined with bone marrow mesenchymal stem cells and titanium alloy internal fixation material were implanted,respectively.RESULTS AND CONCLUSION: One rabbit in the titanium alloy group had local infection and swelling. No rabbit in the alginate group had adverse reactions, such as swelling and local infection. Anteflexion, rear protraction, lateral bending distance and maximum axial pullout force in the alginate group and titanium alloy group were superior to those in the spinal tuberculosis group (P < 0.05), which were close to normal levels (P > 0.05). The above results showed that the alginate gel combined bone marrow mesenchymal stem cells has good biocompatibility with the body after implantation,and the post-implantation spinal stability is good and close to that after implantation of the titanium alloy.

OBJECTIVETo summarize laws of acupoint selection of prescriptions for treatment of cervicogenic headache by acupuncture in modern literature.

METHODSRandomized controlled trials (RCTs) involving acupuncture and moxibustion for treatment of cervicogenic headache were recruited from CBM (1978-2012), VIP (1989-2012), Wanfang Database (1998-2012), CNKI (1979-2012), PubMed (1966-2012), EMbase (1980-2012), and Cochrane Library (Volume 4, 2012). Hand recruitment was also auxiliarily used. The frequency and percentage of common acupoints, the distribution of acupoints along 14 meridians and across each part of the body, the application of specific acupoints, and features of using prescriptions for specific acupoints were statistically described.

RESULTSTotally 37 recruited papers included 42 acupoints and 159 times. Common acupoints covered Fengchi (GB20, 28 times), Jingjiaji (EX-B2, 21 times), Baihui (DU 20, 12 times), Tianzhu (BL9, 1 times), and Ashi point (11 times). Meridians along which acupoints were used mainly covered Foot-shaoyang Gallbladder Meridian, Foot-taiyang Bladder Meridian,and DU meridian. Acupoints were mainly needled from head, neck, and upper limbs. Eight confluence points and luo-connecting point were commonest used as specific acupoints. Acupuncture prescriptions were mostly composed of multiple acupoints. Filliform needle was mainly used in acupuncture methods, followed by electro-acupuncture needle.

CONCLUSIONSModern acupuncture treatment of cervicogenic headache focuses on local specific points and acupoints along meridians. Acupoints were mostly selected from head, neck, and upper limbs by syndrome typing of Chinese medicine.

Objective To research the mechanism of TX0201 abstracted from Heart-Regulating Formula in treatment of rats with Alzheimer's disease (AD). Methods The rat model of AD was induced by A?25-35 injected into the bilateral amygdale. To observe the spatial learning and memory ability, by means of RT-PCR and immunohistochemistry analysis, the expression of ?-amyloid precursor protein (APP), glial filament acid protein (GFAP) in the brain of the model animal were examined. Results In AD model group, the spatial learning and memory ability was damaged significantly, the expression of APP mRNA increased in its cortex and hippocampus. GFAP immunopositive signal, and IL-6 mRNA in cortex and hippocampus and the expression of IL-1? mRNA in hippocampus were upregulated. TX0201 improved the spatial learning and memory disturbance, decreased the expression of APP mRNA and IL-1? mRNA in hippocampus, downregulated GFAP and IL-6 mRNA in cortex and hippocampus. Conclusions The model showed the characteristic of AD such as memory hypofunction. TX0201 could partially ameliorate memory function, decrease the expression of APP mRNA in hippocampus, alleviate inflammation-immunity reaction, that is one of the effect mechanisms of TX0201.

The functions of the top 15 medical APP were compared.Their major functions of medical advice, information service and medical service were analyzed.The key functions of mobile medical APP used in China were described with suggestions for their development.

Objective To observe the function improvement of deep venous valve after superficial vein surgery of lower extremity by ultrasound.Methods Sixty patients(70 lower limbs)with primary deep venous insufficiency were enrolled tO accept surgical management of vein systems.All Datients were detected with color Doppler ultrasonography,their deep venous hemodynamics indices were measured and recorded before operation and 6 months after operation. Results The total improvement rate of the deep venous hemodynamics after superficial vein surgery was 65.7%.The valve function of suPerficial femoral vein and popliteal vein were improved after operation,and there was no significant difference between the two veins in effectiveness.The improvement for deep venous reflux had no significant difference between two surgical methods. Conclusions The superficial vein surgery of lower extremity can improve deep vein valve function in some extent.
