OBJECTIVETo investigate the effect of miRNA-101 on the expression of the enhancer of zeste homolog 2 (EXH2) in human androgen-independent prostated cancer LNCaP cells.

METHODSWe divided LNCaP cells into a blank control, a negative control, and a miRNA-l01 transfection group, constructed the vector by transfecting synthetic miRNA-101 mimics into the LNCaP cells, and evaluated the efficiency of transfection by fluorescence microscopy. Then we determined the expression level of EZH2 mRNA by qRT-PCR in the three groups of cells and that of the EZH2 protein in the negative control and transfection groups by Western blot.

RESULTSGreen fluorescence signals were observed in over 70% of the LNCaP cells in the transfection group after 24 hours of transfection. At 72 hours, the expression of miRNA-101 was significantly upregulated in the transfected cells (P < 0.01), that of EZH2 mRNA was remarkably lower in the transfection group (0.01 ± 0.10) than in the blank control (0.95 ± 0.40) and negative control (0.86 ± 0.30) groups (both P < 0.01), and that of the EZH2 protein was increased in the negative control but decreased in the transfection group with the extension of culture time.

CONCLUSIONmiRNA-101, with its inhibitory effect on the expression of EZH2 in LNCaP cells, is a potential biotherapeutic for prostate cancer.

Objectives To assess the clinical efficacy, safety, and feasibility of autologous transplantation of mobilized peripheral blood mononuclear cells (PBMNCs) for patients with peripheral arterial occlusive disease (PAOD) of the lower extremity. Methods A total of 152 patients with PAOD of the lower extremity were enrolled into this non-controlled observational study from November 2003 to March 2006. All patients received subcutaneous injections of recombinant human granulocyte colony-stimulating factor (G-CSF, 450600 μg/day) for 5 days in order to mobilize stem/progenitor cells; their PBMNCs were collected and transplanted by multiple intramuscular injections into ischemic limbs. Patients were followed up for at least 12 weeks. Results At 12 weeks, primarymanifestations,including lower limb pain and coldness, were significantly improved in 137 (90.1%) of the patients; limb ulcers improved or healed in 46 (86.8%) of the 53 patients, while 25 of the 48 (47.9%) patients with limb gangrene remained steady or improved. Ankle-brachial index (ABI) improved in 33 (22%) of the cases, and TcPO2 increased in 45 (30%) of the cases. Angiography before treatment, and at 12 weeks after treatment, was performed in 10 of the patients and showed formation of new collateral vessels. No severe adverse effects or complications specifically related to cell transplantation were observed. Conclusion Autologous transplantation of G-CSF-mobilized PBMNCs might be a safe and effective treatment for lower limb ischemic disorder.(J Geriatr Cardiol 2006; 3:178-80.)

Objective To investigate the distribution of water-borne fluoride and the current situation of endemic fluorosis in Yan'an city in 2006, and to evaluate the effect of water defluoridation project by improving driking water quality. Method In 2006 in Yan'an city, 5 samples from water source were collected in each selected village that was chosen according to 5 directions of East, West, South, North, and Central. Meanwhile, 1 sample from water source, 1 sample from water processing factory and 2 tap water samples were collected from each water defluoridation project. Water fluoride was determined by spectrophotometric method, teeth and skeletal fluorosis examination were performed by Dean method and "national criteria of endemic skeletal fluorosis diagnosis of China" in children aged 8-12 year and adults, respectively if water fluoride level > 1.00 mg/L Results Of 726 water samples from 293 villages tested, samples from 25 villages had higher fluoride( > 1.00 mg/L), and these villages covered a population of 11 610 people and most of these people were in Wuqi and Yanchuan counties. Water fluoride ranged from 0.10 mg/L to 3.50 mg/L, with median being 0.59 mg/L. Of 100 water samples from 25 water defluoridation projects, only 1 sample exceeded the national criteria in Yanchuan, and Wuqi counties, respectively,with fluoride level being 1.85 mg/L and 1.60 mg/L, respectively, and population exposed was 3083 and 708, respectively, with water fluoride ranged 0.30 - 2.00 mg/L In the examination of 1281 children aged 8 - 12, we detected 238 cases of dental fluorosis, and the detection rate reached 18.58%; 13 900 adults were checked, and 375 cases were confirmed of skeletal fluorosis, a detection rate reached 2.70%. Conclusions Yan'an has a wide range of water with high fluoride and severe fluorosis people. The water defluoridation projects need to be further improved. The task of prevention of endemic fluorosis is still arduous, and we should speed up the implementation of comprehensive water defluoridation measures.

OBJECTIVETo study the relationship between life style and metabolic syndrome (MS).

METHODSUsing identical protocol and questionnaire, 173 patients with MS and 173 without MS selected from the general population undergoing physical examinations in Guangdong General Hospital were surveyed for the risk factors of MS in their life style, and logistic regression analysis was performed to identify the risk factors.

RESULTSMS was significantly related to overweight, prolonged maintenance of sitting posture, and heavy life or work stresses, among which overweight was the most important factor contributing to MS (OR=11.442, P<0.000). Regular exercise, long exercise time, and anxiety were protective factors for MS. Meat intake, smoking, time of getting sleep and insomnia were not found to relate to MS.

CONCLUSIONMS is correlated to some general habits in daily life, and a healthy life style may help in the prevention and treatment of MS.

OBJECTIVETo provide an appropriate angle and depth of needle insertion in acupuncture at Zusanli (ST 36) and avoid injuring the nerve and blood vessel and exert the most effect.

METHODSEighty adult lower-limb samples were used to dissect and observe the relative layered structures and adjoining important nerves and blood vessels in needling Zusanli (ST 36) according to the national standard.

RESULTSThe needling depth from the skin to the interosseous membrane and from the skin to posterior border of tibialis posterior is (2.22 +/- 0.31) cm and (4.42 +/- 0.53) cm, respectively. There are flabellate branches of anterior tibial arteries and deep peroneal nerves around the needle in the superficial layer of interosseous membrane. The vessel and nerve bundles containing tibial nerve and posterior tibial vessels can be touched when the needle body past through tibialis posterior.

CONCLUSIONIt is recommended that ideal average depth of acupuncture is 2.22 cm and the maximum depth is 4.42 cm for oblique needling Zusanli (ST 36). When it is injected, the needle should be perpendicularly inserted or deviated slightly to the direction of tibia and paralleled to medial surface of tibia. And the safe needling depth is generally less than 5 cm. The point of the body surface between tibialis anterior and extensor digitorum longus at 3 cun below Dubi (ST 35) is also an effectively stimulating point.

OBJECTIVETo investigate the methods and effects of secondary intervention for mid-long term complications of endovascular repair (EVR) in aortic diseases.

METHODSFrom May 1999 to Jun 2007, 21 patients with mid-long term complications after EVR were treated in our center. Of these cases, 15 cases received first EVR for abdominal aortic aneurysm (AAA), 3 cases for thoracic aortic aneurysm (TAA) and 3 cases for aortic dissection (TAD). The mid-long term complications included 11 cases of type I endoleak, 4 cases of type II endoleak, 2 cases of type III endoleak and 4 cases of migration of stent grafts. Proximal or distal extensions were used for type I and III endoleak in 9 cases. Fenestrated, scallop and bifurcated stent grafts were used to reconstruct the aortic arch in 3 cases. Emboli technique was used in treating type II endoleak. Thrombectomy and bypass technique were used in 4 cases with stent graft limb occlusion. One ruptured AAA accepted open surgery.

RESULTSSecondary endovascular technique were undergone in 20 (95.2%) cases. One case died in 30 days after the secondary intervention and endoleak remained after the secondary operation in 5 cases. Three cases died of the secondary intervention.

CONCLUSIONSEndoleak and limb occlusion were the chief mid-long complications after EVR. Secondary endovascular technique can be used in most cases and carries great challenges in aortic arch lesions.
