Twenty-nine thyroid tissue samples were collected from patients with thyroid nodules.The total RNA were extracted,the gene expressions of TFF3,HMGA2,C1orf24,and DDIT3 were detected by RT-PCR.In comparison with normal thyroid tissues,the expression of C1orf24 mRNA was decreased in the follicular thyroid adenoma (FTA) group,but increased in the follicular thyroid carcinomas (FTC) group.The expressions of DDIT3 and HMGA2 mRNA were increased in both FTA and FTC groups,and were even higher in the latter.The expressions of TFF3 mRNA level were decreased in FTA and FTC.The data suggested that molecular markers C1ort24,DDIT3,HMGA2,and TFF3 in thyroid tissue seem to be helpful in the differential diagnosis between follicular adenomas and carcinomas.

Objective To investigate the correlation between the mutation in serum lipoprotein-associated phospholipase A2(Lp-PLA2) Ile198Thr, Val279Phe and cerebral infarction in Chinese Han population of Jiangsu Province. Methods One hundred fifty patients with cerebral infarction and 100 healthy controls in Chinese Han population of Jiangsu Province were recruited. The correlation between Val279Phe and Ilel98Thr mutation in Lp-PLA2 gene and cerebral infarction was analyzed using polymerase chain reaction and denaturing high performance liquid chromatography. Results The Val279Phe genotype and the mutant allele frequency in the cerebral infarction group were significantly higher than those in the control group (χ2 were 6. 31and 5. 32, respectively, all P ＜0. 05), and there was no significant difference between the Ile198Thr genotype and the mutant allele frequency in the control group (χ2 were 0. 039 and 0. 037, respectively, all P ＞0. 05). Conclusions The Val279Phe mutation in Lp-PLA2 gene may be a genetic risk factor for cerebral infarction in Chinese Han population of Jiangsu Province.

Objective To investigate the expression of brain-derived neurotrophic factor (BDNF) and nerve growth factor (NGF) after cerebral infarction and treatment with curcumin combined with electroacupuncture.Methods Middle cerebral artery occlusion was successfully introduced to simulate cerebral infarction in 60 healthy,male Wistar rats.They were then randomly divided into a control group,an electroacupuncture group,a curcumin group and a curcumin combined with electroacupuncture group (the observation group),each of 15.After the modeling,the four groups were given the planned interventions for 2 weeks,with the control group receiving no intervention.All of the rats were sacrificed after neurobehavioral scoring and immunological staining of brain tissue from the infarction area was used to detect the expression of BDNF and NGF.Results The average Bederson score in the observation group was significantly lower than those of the other groups.Cells expressing BDNF and NGF were significantly more numerous in the observation group than in the other three groups.Conclusion Curcumin combined with electroacupuncture can significantly improve the expression of BDNF and NGF in the infarcted area,and this may play a neuroprotective role.

Objective The aim of this study was to evaluate the feasibility of three-dimensional printing (3DP) for the preparation of porous titanium implant and to investigate the impacts on microstructure and mechanical properties with different sintering temperatures.Methods The CAD model of the specimens was designed to be 25 mm in diameter,20 mm in height,and with 0.5 mm pore size mesh.On every cross-section,80％ bonding area was designed.Titanium powder (purity of 98.5％,75 μm diameter) was selected as raw material.Polyvinyl alcohol powder (160 μm diameter) was selected as a binder,and polyvinylpyrrolidone powder was selected as an auxiliary binder.The green porous titanium implants were fabricated by 3DP followed by sintering at 1 200,1 300,1 400 ℃,separately,under the protection of argon gas.After sintering,the properties of porous titanium implants were evaluated,including the porosity,microstructure,microhardness,compressive strength and elastic modulus.Results After sintering,the specimen had uniform contraction and no obvious distortion.The specimen sintered at 1 200,1 300 and 1 400 ℃ sintering temperatures had porosity of (65.01±1.03)％,(46.73±0.73)％ and (41.06±0.31)％,hardness of 115.2±0.6,148.6±1.1 and 182.8±2.1,elastic modulus of (5.9±0.5),(16.2±0.9) and (34.8±1.5) GPa,compressive strength of (81.3±4.3),(135.4±8.5) and (218.6±7.1) MPa,respectively.A porous structure with three-dimensional network of connected pores was observed under scanning electron microscope.Conclusion It is feasible to fabricate porous titanium implants by three dimensional printing technique.The mechanical properties of the porous titanium implants match well with bone tissue which has excellent biomechanical compatibility.

OBJECTIVETo compare the difference in the clinical efficacy on primary trigeminal neuralgia (PTN) between the comprehensive therapy of electroacupuncture (EA) at qi streets acupoints combined with spinal regulation method and medication with carbamazepine (CBZ).

METHODSSixty patients were randomized into a comprehensive therapy group (30 cases) and a medication group (30 cases). In the comprehensive therapy group, the acupoints at qi streets on the head such as Taiyang (EX-HN 5) and Sishencong (EX-HN 1) and those at qi streets on the chest and abdomen such as Shenshu (BL 23), Zhongwan (CV 12) and Guanyuan (CV 4), etc. were selected. After arrival of qi, EA was attached on 2 to 4 groups of acupoints. After acupuncture, the spinal regulation method was applied. This comprehensive therapy was given once a day. In the medication group, CBZ was used for oral administration, 100 mg at the first time, twice a day, and 400 to 600 mg each day as the maintenance dose. Separately, before and after treatment, in 2 and 6 months in follow-up, pain rating index (PRI), life satisfaction index B (LSI-B) and hamilton depression scale (HAMD) were adopted to evaluate comprehensively the clinical efficacy in the two groups and compare the adverse reaction during the treatment between the two groups.

RESULTSAfter treatment, the curative and markedly effective rate in the comprehensive therapy group was 76.7% (23/30), which was better than 63.3% (19/30) in the medication group (P < 0.01). The difference in PRI was not significant after treatment between the two groups (all P > 0.05). In 2 and 6 months follow-up, PRI grade in the comprehensive therapy group was superior to that of the medication group (both P<0. 05). After treatment and in follow-up, HAMD score was all reduced in the two groups (P < 0.01, P < 0.05) and the result in follow-up in the comprehensive therapy group was significant as compared with that in the medication group (all P<0. 05). After treatment, LSI-B score was increased obviously in the two groups (all P < 0.05) and the result in the comprehensive therapy group was better than that in the medication group (P < 0.05). The incidence of adverse reaction in the comprehensive therapy group was 16.7% (5/30), which was lower than 30.0% (9/30, P < 0.01) in the medication group.

CONCLUSIONThe comprehensive therapy of EA at qi streets acpoints combined with spinal regulation method achieves the long-term efficacy on PTN as compared with oral administration of CBZ in terms of the improvement of psychological condition, analgesia and life quality. It is the safe, effective and stable therapy.

Polymeric micelles have exhibited attractive properties as drug carriers, such as high stability in vivo and good biocompatibility, and been successfully used to dissolve various drugs of poor aqueous solubilities. In this study, we developed a new type of polymeric micelles with mannose-mediated targeting and pH-responsive drug release properties for anticancer drug delivery. The polymeric micelles were prepared from an amphiphilic polymer, poly (glycidyl methacrylate)-g-mannose (PGMA-Mannose). An anticancer drug, doxorubicin (DOX), was encapsulated into the micelles during the micellization, and could be released rapidly under acidic condition. The specificity of cellular uptake of the micelles by two different cell lines was studied using confocal laser scanning microscopy and the MTT assay. DOX-loaded micelles were efficiently trapped by mannose-receptor-overexpressing cancer cells MDA-MB-231, whereas mannose- receptor-poor cells HEK293 showed much lower endocytosis towards the micelles under the same conditions. Thus, DOX-loaded micelles displayed higher cytotoxicity to MDA-MB-231 cancer cells as compared with free DOX. The present study demonstrates that PGMA-Mannose micelles are a promising targeted drug delivery system for cancer therapy.
