Objective To analyse effects of the serum levels of thyroid peroxidase antibodies (TPOAb) on antithyroid drugs (ATD) treatment in patients with incipient Graves disease (GD). Methods A total of 121 patients with incipient GD, who were used anti thyroid drugs for 12 months, were included in this study. Patients were dvided into two groups:TPOAb negative group (TPOAb≤35 IU/mL, n=49) and TPOAb positive group (TPOAb>35 IU/mL, n=72). According to the degree of TPOAb drops the TPOAb positive group was sub-divided into low level positive group (35 IU/mL1 000 IU/mL, n=20). The ATD total dosage for 12 months and thyroid-stimulating hormone (TSH), which returned to normal rate after treatment of 3, 6 and 12 months, were compared between groups. Results ATD total dose was lower in TPOAb positive group (1 743.82±265.38) mg than that of negative group (1 889.18 ±125.51) mg. The ATD total dosages were (1 759.71±230.29) mg, (1 793.75±299.02) mg, (1 731.54± 236.44) mg and (1 710.00 ± 290.73) mg for low level TPOAb positive group, medium level TPOAb positive group, high level TPOAb positive group, and very high level TPOAb positive group respectively. The recovering ratio of TSH was significantly higher in TPOAb positive group than that of TPOAb negative group after 3-month treatment (P<0.05). Conclusion TPOAb positive serum can lead to shorten the course of ATD treatment and reduce the total amount of ATD treatment in GD patients.

Aim To observe the effects of Breviscapine (Bre) on the contractions induced by noradrenaline (NA) and high potassium in rabbit aorta strips and to investigate the relationships of these effects to the changes of intracellular free calcium( i). Methods The effects of Bre on the concentration-response curves for NA and high potassium, and on the transient contractions induced by NA and caffeine in Ca 2+-free medium and the sustained contraction by NA after replenishing Ca 2+ were surveyed using rabbit aorta strips; the changes of i increased by NA and high potassium in the presence of Bre were determined using fura-2/AM loaded cultured smooth muscle cells of rabbit aorta. Results Bre shifted the concentration-response curve for NA to right in a dose-dependent manner , but shifted that for high potassium to left; it inhibited the transient contraction induced by NA and caffeine in the Ca 2+-free medium and the sustained contraction induced by NA after replenishing Ca 2+; Bre inhibited the i increased by NA, but enhanced that increased by high potassium in the smooth muscle cells of rabbit aorta. Conclusion Bre inhibits the contraction induced by NA through its inhibition effects on Ca 2+-influx and Ca 2+-release ; it enhances the Ca 2+-influx induced by high potassium, but the mechanism by which Bre enhances the high potassium inducing Ca 2+ -influx is not known.

Objective To investigate the distribution of 16S rRNA methylase genes in Klebsiella pneumoniae strains producing Klebsiella pneumoniae ealbapenenase type 2(KPC-2).Methods A total of 37 Klebsiella pneumoniae isolates producing KPC-2 were collected.The minimal inhibitory concentrations (MICs)of these strains to amikacin,gentamyein and netilmicin were determinated by agal dilution method.Six 16S rRNA methylase genes(armA,rmtA,rmtB,rmtC,rmtD and npmA)were detected by PCR.Results The resistant rates to amikacin,gentamycin and netilmicin were 97.3%(MIC50≥1024μg/mL).Among those resistant strains,8 were armr/A positive,25 were rmtB positive,4 were both armA and rmtB positive.and no other 16S rRNA methylase genes were found.The total positive rate of 16S rRNA methylase genes was 78.4%(29/37).Conclusion 16S rRNA methylase genes armA and rmtB ale prevalent in Klebsiella pneumoniae strains producing KPC-2.

OBJECTIVETo compare the effect and impact of holmium laser enucleation of the prostate (HoLEP) and 120-W thulium: YAG vapoenucleation of the prostate (ThuVEP) on erectile function in the treatment of benign prostatic hyperplasia (BPH).

METHODSWe retrospectively analyzed 93 cases of symptomatic BPH treated by HoLEP or 120 W ThuVEP. We made comparisons between the two groups of patients in the baseline and postoperative clinical and surgical indexes as well as their IPSS, quality of life (QOL), maximum flow rate (Qmax), postvoid residual urine volume (PVR), and IIEF-EF scores before surgery and during the 12-month follow-up.

RESULTSThuVEP, in comparison with HoLEP, achieved a significantly shorter operation time ([57.6 +/- 12. 8] vs. [70.4 +/- 21.8] min, P = 0.001) and a higher laser efficiency ([0.71 +/- 0.18] vs. [0.62 +/- 0.19] g/min, P = 0. 021). At 1, 6, or 12 months of follow-up, no significant differences were observed in IPSS, OOL, Omax, and PVR between the two groups (P > 0.05). Both the HoLEP and ThuVEP groups showed low incidences of complications and remarkably improved IIEF-EF scores at 12 months postoperatively, but with no significant differences (both P > 0.05). However, in those with relatively normal erectile functions before operation, the mean IIEF-EF score was reduced from 22.8 +/- 2.2 preoperatively to 21.0 +/- 2.7 after HoLEP, (P = 0.036).

CONCLUSIONBoth HoLEP and 120W ThuVEP are effective and safe in the treatment of BPH. Compared with HoLEP, 120 W ThuVEP has even a higher laser efficiency. However, neither can significantly improve erectile function, and HoLEP may have a short-term negative impact on the relatively normal erectile function of the patient.

OBJCETIVETo investigate the method of separation of culture of bone microvascular endothelial cells (BMECs) of human femoral head in vitro.

METHODSFrom October 2013 to January 2014,15 femoral heads without pathologic change from patients resected during hip replacement were selected involving 2 males and 13 females with a mean age of 71.2 years old ranging from 38 to 92. Cancellous bone in femoral head was bited into broken bone grain and transfered into medium in aseptic contidion. Cells were isolated by the methods of enzymic digestion and density gradient centrifugation,purified by differiential attachment. The characteristics of cells was observed by inverted microscope. vWF and CD31 immunofluorescence analysis was applied for identification of cells.

RESULTSThe number of cells was positively correlated with patients' age after 24 hours in primary culture. The older patients had the less cells numbered. After 4 to 5 days' culture, primary cells appeared short spindle,polygon shaped and cobblestone-like morphology. After 7 to 10 days' culture, primary cells proliferated densely, became fusion, arranged in swirl, and contact inhibition appeared significantly. Immunofluorescence staining revealed the cells were 100% positive for vWF and CD31, and it showed that the cultured cells were BMECs.

CONCLUSIONIt was a simple, steady, effective method with good reproducibility, by which highly purified human BMECs can be obtained.

Traditional Chinese medicine is a treasure of Chinese culture, absorbing the wisdom of the Chinese people. Continuous application of new technologies makes traditional Chinese medicine research advance with the times. After several years of development, high-throughput transcriptome study has become a mature research tool in biology. This paper reviewed the advances in medicine transcriptome study, and compared two sequencing platforms, Roche's GS FLX platform and Illumina's HiSeq 2000 platform. Moreover, this paper introduced medicine transcriptome analysis process, with Panax quinquefolius and Lonicera japonica for examples, showing the characteristics of traditional Chinese medicine transcriptome studies. High-throughput transcriptome studies facilitate traditional Chinese medicine research with overall understand of functional genes, give clear elucidation of metabolic pathways, lay molecular foundation for the traditional Chinese medicine research and offer modern interpretation for traditional Chinese medicine theory. However, the current study faces several difficulties, including weak molecular basis, high sequencing cost and staff shortages in data anaysis. In the future, with the development in sequencing technology, the combination of transcriptome and other genomics, such as proteome and metabolome, will lay a solid foundation for the new high-throughput screening and developing model for the traditional Chinese medicine industry.

Objective To explore protective effect of Heme oxygenase-1(HO-1) on irradiation-induced endothelial cell apoptosis.Methods Human endothelial cell line EA.hy926 were administered with or without HO-1 activator Copp and/or HO-1 inhibitor Znpp,respectively.Then,cells were treated with or without 8 Gy radiation.The HO-1 protein expression of cells were assessed with Western blotting and apoptosis of cells treated with irradiation were evaluated with flow cytometry.Moreover,cytochrome C releasing into cytosol were also determined by Western blotting. Results In PBS+R group,HO-1 protein expression of EA.hy926 was low posterior to irradiation.When cells were preconditioned with Copp and/or Znpp,then recieved with 8Gy irradiation,the HO-1 protein expression of EA.hy926 increased significantly in comparision with the PBS+R group(P

OBJECTIVETo explore the correlationship between platelet count and efficacy of traditional Chinese medicine (TCM) or Western medicine (WM) in treating rheumatoid arthritis (RA) patients.

METHODSA total of 356 patients with confirmed diagnosis of active RA from 9 clinical centers were randomly assigned to the TCM group (184 cases) and the WM group (172 cases). The TCM group was treated with basic therapy (administration of glucosidorum tripterygll totorum and Yishen Juanbi Pill) and TCM syndrome differentiation dependent treatment, while the WM group was treated with non-steroidal anti-inflammatory drugs and slow-acting anti-rheumatic drugs. The therapeutic efficacy was assessed with ACR20, the joint damage degree of both hands was evaluated by X-ray.

RESULTSThe platelet count was positively correlated to the X- ray grading of joint damage, namely, patients with a more severe joint damage often presented a higher platelet count. After treatment, in patients with joint damage of X-ray grade II or III and effectively treated with TCM, also in patients with joint damage of grade III and effectively treated with WM, the platelet count was lower than that in those treated ineffectively.

CONCLUSIONPlatelet count is closely correlated to the efficacy of drug therapy, therefore, it may be taken as an important index for judging the curative effect of therapeutic approach in treating RA patients.
