Objective To investigate the changes of iodide uptake and the expression of thyroidspecific genes in poorly differentiated follicular thyroid carcinoma (FTC) cells after transfection of human TSH receptor (hTSHR) gene in vitro. Methods The recombinant eukaryotic expression plasmid PcDNA3. 1/hTSHR-cDNA was transformed into DH5a bacterial for amplification and then the recombinant plasmid was extracted. The recombinant was identified with PCR amplifying, restriction enzyme digestion analysis and DNA sequencing. The recombinant plasmid pcDNA3.1/hTSHR was transfected into FTC-133 cell line by lipofectin methodin vitro. Immunofluorescence, iodide uptake studies and real time-PCR were applied to detect target protein expression. Statistical analysis was performed with t-test using SPSS 13. 0 software. Results Kpn Ⅰ and Xba Ⅰ restriction enzyme digestion, PCR amplifying and DNA sequencing confirmed that pcDNA3. 1/hTSHR was successfully constructed. After transfection of the recombinant plasmid pcDNA3. 1/hTSHR-cDNA and the stimulation of hTSH, the tumor cells displayed the expression of hTSHR protein at cell surface and cytoplasm. The iodine uptake in pcDNA3. 1/hTSHR transfected cells was 2. 9 times higher than that of control(pcDNA3.1(+) transfected cells) group(t = 28.63, P <0. 01). The expression of TSHR,NIS, TPO and Tg (mRNA levels) in pcDNA3. 1/hTSHR transfected cells were also significantly elevated by 1.74 (t =5.959, P<0.01), 7.2 (t =3.807,P<0.05), 2.88 (t=4.769,P<0. 01) and 2.67 times (t=6.388,P <0.01) respectively compared to those of the control group. Conclusion The study demonstrates that iodide uptake may be reactivated by hTSHR receptor gene transfection in poorly differentiated FTC cell.

Objective To summarize the incidence and treatment experience of the effectiveness and adverse reactions of the different immunosuppressive protocols and to increase the long-term survival rate in kidney recipients. Methods Single-center retrospective analysis was performed on 3102 cases of kidney transplant recipients in effectiveness and adverse reactions of different immunosuppressive protocols. The immunosuppressive protocols were as follows: CsA + Aza + Pred,low dose CsA + MMF + Pred, low dose Tac + MMF + Pred, low dose CsA + SRL + Pred, and low dose Tac+ SRL+ Pred. Results The 1-, 5-, 10-year survival rate of patients/kidney in low dose CsA + MMF + Pred protocol was higher than that in CsA + Aza + Pred protocol. The incidence of adverse reactions, such as hypertension, hyperuricemia, kidney and liver toxicity, and leukopenia was significantly lower, but the incidence of diarrhea was significantly higher in CsA + MMF + Pred protocol than in CsA + Aza + Pred protocol (all P<0. 01). The incidence of hyperglycemia was significantly higher (P<0. 05), and that of hairy and gingival hyperplsia was significantly lower (P<0. 05) in low dose Tac+ MMF+ Pred than in low dose CsA+ MMF+ Pred protocol. The incidence of hyperlipidemia in low dose CsA (or Tac)+ SRL + Pred was significantly higher than in CsA (or Tac)+ MMF+ Pred protocol (P<0. 05). The incidence of hirsutism in low dose Tac + SRL + Pred was significantly lower than that in CsA + SRL + Pred protocol (P < 0. 05). The incidence of hyperglycemia in low dose Tac + SRL + Pred was significantly higher than that in low dose CsA + SRL + Pred protocol. Conclusion The triple drug protocol with a low dose of CsA (or Tac)+ MMF+ Pred significantly improved the survival of renal transplant recipients and graft, and reduced the incidence of adverse reactions, especially Tae + MMF + Pred protocol. Adjustment of the immunosuppressant dosage and protocol, improvement of eating habits, exercise, reduction of blood pressure, reduction of blood lipid, and control of blood glucose were particularly important in preventing and controlling adverse reactions during kidney transplantation.
6. Study on technology of innovative component structure in chinese materia medica preparation based on enhanced bioavailability
Chinese Traditional and Herbal Drugs 2017;48(16):3280-3287
Modernization of Chinese materia medica (CMM) is the main direction of development of CMM. As a complex system, CMM has the whole characteristics with multi-component, multi-channel and multi-target. However, the lack of material base of CMM and the unknown mechanism of action restrict the development of modern medicine. Strengthening the theoretical exploration of Chinese medicine components, which could improve the technical level of component preparation and promote the development of CMM component preparation, is the key to realize the modernization of CMM. This paper reviews the preparation technology of CMM component combined with components of biological pharmacy classification system for the purpose of improving the bioavailability of components based on the “component structure” theory.

Objective To compare the safety and efficacy of direct and remedial rotational atherectomy in the treatment of heavily calcified coronary artery lesions.Methods We retrospectively reviewed 58 patients admitted in the Shanghai Chest Hospital and Liaocheng People Hospital from May 2012 to July 2015 who had received stent implantation and rotational atherectomy.The 58 patients were divided into two groups which were the direct atherectomy group (n =27) and the remedial atherectomy group (n =31).General clinical date,lesion and procedural characteristics,intraoperative complications,in-hospital and follow-up MACCE were compared between the two groups.Results There were no differences between the two groups in general clinical date intraoperative complications,amount of contrast agent used,proceduraltime,rates of in-hospital and follow-up MACCE.Nevertheless,compared with the direct artherectomy group,the remedial group had more number of balloon dilations during procedure [3 (1,5) vs.2 (1,2),P < 0.001] and higher peak cardiac troponin levels [1.1 (0.3,3.0) μg/L vs.0.5 (0.1,2.3) μg/L,P =0.032].Conclusions Remedial rotational atherectomy with drug-eluting stent had the same safety and efficacy as direct atheretomy with drug-eluting stent in treating patients with heavily calcified coronary lesions.It is reasonable and safe to transform routine PCI to remedial rotational atherectomy when the 2.0 mm semi compliant balloon or/and 2.5 mm non-compliant balloon cannot pass through or dilate the lesions.

Objective To investigate the effects of HLA matching on long survival of patients with kidney transplantation. Methods In 2508 cases of renal transplants, based on Ag M standard, in 0 MM-6 MM (7 groups), the effects of HLA matching on the survival rate of 1 year, 5 years and 10 years, and the incidence of renal acute rejection (AR) in renal allografts were analyzed. Results Only 7 cases had 0-missmatches, and most cases had 2 or 3 missmatches. In the group of zero antigen mismatches, the incidence of renal AR was 5 %, lower than other groups (P<0. 01); in the group of six antigen mismatches, the incidence of AR was 23 %, obviously higher than other groups (P<0. 01). The 1-year, 5-year and 10-year survival rate was 97 %, 90 %, 88 % in the group of zero antigen mismatches; 94 %, 86 %, 83 % in the group of one antigen mismatches; 94 %, 84 %, 82 % in the group of two antigen mismatches; 93 %,85 %, 81% in the group of three antigen mismatches; 91%, 82 %, 74 % in the group of four antigen mismatches; 90 %, 81%, 72 % in the group of five antigen mismatches; 88 %, 80 %, 70 % in the group of six antigen mismatches. Conclusion Good HLA matching can significantly reduce the incidence of AR of renal allografts and increase the survival rate. If recipients are offered to choose those with HLA antigen mismatches ≤3, it is good for the effective use of donor kidneys, the prevention of rejection, and the improvement of the transplantation results.
