Objective To explore the relationship of asthmatic patients with Abnormal Savda and ECP,T-IgE,S-IgE and FEV1. Methods Seventy six cases of asthmatic patients were diagnosed according to the body fluid theory of Uygur Medicine. Among them,there were 30 cases of asthmatic patients with Abnormal Savda and 46 cases of asthmatic patients with non-abnormal Savda. The level of serum ECP,T-IgE,S-IgE and FEV1 were tested quantitively. Results There were significant differences on the level of serum ECP,T-IgE,S-IgE in all three groups (P

Purpose To analyze the effects of full length and N-terminal fragment of serum response factor (SRF-Full and SRF-N) on TGF-β1-induced differentiation in c-Kit + cardiac stem cells (CSC).Methods Rat SRF-Full and SRF-N (1-254 aa) coding sequences were obtained from cDNA library and cloned into the linearized lentviral vector GV358 (Ubi-MCS3FLAG-SV40-EGFP-IRES-puromycin) to generate the recombinant vectors,and then positive clones were selected and sequenced after transducing the competent cells with recombinant vectors.The recombinant lentvirus were packaged through transfecting the HEK293T cells with SRF-Full,SRF-N overexpressing plasmids and viral packaging plasmids.Neonatal SD rat cKit + CSCs were isolated via magnetic activated cell sorting,and TGF-β1-induced differentiation in SRF-Full and SRF-N overexpression virus-infected CSCs was assessed by quantitative PCR.Results SRF-Full and SRF-N coding sequences were successfully obtained and properly cloned into the linearized GV358.The positive clones were selected and further confirmed by sequencing.With the help of packaging plasmids,the SRFFull and SRF-N overexpressing plasmids-transfected HEK293T cells successfully produced the lentiviral particles with the titer of 2 × 108 TU/mL,and the SRF-Full-Flag and SRF-N-Flag fusion protein were detected by Western blot in virus-infected HEK293T cells.Addition of TGF-β1 significantly induced upregulated mRNAs in cardiomyocyte markers (Nkx2.5,Gata4,cTnI) and smooth muscle cell marker (SM22α) but not the epithelia cell marker (vWF) in CSCs.Overexpression of SRF-Full facilitated TGF-β1-triggered cardiomyocyte differentiation.However,SRF-N exerted anti-differentiation effects in TGF-β1-treated cells.Conclusion The SRF-Full and SRF-N overexpressing recombinant lentiviral vectors are successfully constructed.SRF-Full facilitates while SRF-N suppresses TGF-β1-induced cardiomyocyte differentiation in c-Kit + CSCs.

BACKGROUNDThe most significant biological change in intervertebral disc degeneration is the decrease of chondrocyte specific gene and protein expression of Sox9 and collagen type II. Interleukin-1 (IL-1) is not expressed in the normal intervertebral disc tissue but increases in the degenerated intervertebral disc tissue. This suggests that IL-1 may play a role in regulation of the expression of Sox9 and collagen type II.

METHODSHuman intervertebral disc cells were isolated and cultured. Sox9 and collagen type II expression during treatment with IL-1, with or without the nuclear factor-kappaB (NF-kappaB) activity inhibitor curcumin, were detected by using reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting, and the activity of the NF-kappaB signaling pathway was detected by the electrophoretic mobility shift assay (EMSA).

RESULTSIL-1 lowered the mRNA level and protein expression of Sox9 and collagen type II in the cultured intervertebral disc cells in a dose dependent manner (P < 0.05), and this effect was attenuated by curcumin. Curcumin alone had no effect on Sox9 and collagen type II expression (P > 0.05). IL-1 at concentrations of 0.1 ng/ml, 1 ng/ml and 10 ng/ml could stimulate the activity of NF-kappaB in the intervertebral disc cells in a dose dependent manner (P < 0.05) that was inhibited by curcumin.

CONCLUSIONSWe demonstrated the previously unknown function of IL-1 in inhibiting Sox9 and collagen type II via NF-kappaB in the intervertebral disc cells. This inhibition can be attenuated by curcumin, which is an effective NF-kappaB activity inhibitor.

Sorafenib is a multi-targeted tyrosine kinase inhibitor that inhibits Raf kinase and the vascular endothelial growth factor receptor intracellular kinase pathway and is the first agent to demonstrate a statistically significant improvement in overall survival for patients with advanced hepatocellular carcinoma (HCC). However, there were few cases of partial or complete response reported in the previous studies. We herein report a case of dramatic partial response in a patient who had advanced HCC with multiple lung metastasis and portal vein thrombosis treated with sorafenib.

The authors attempted to analyse the factors influencing the mortality involved in aneurysm surgery based on 38 cases of intracranial surgery for anterior communicating aneurysms, and obtained the following conclusion. 1. The surgical results are much better when the aneurysm surgery is delayed over one week after the occurrence of aneurysmal rupture, if there is no evidence of intracerebral hematoma. Administration of a massive dosage of epsilon aminocaproic acid in the waiting period prior to aneurysm surgery seems to be effective for preventing recurrence of bleeding from the aneurysm. 2. The direction of the anterior communicating aneurysm should be clearly visualized on a cerebral angiogram so that the most effective aneurysmal approach can be selected in surgery. 3. Microsurgery and hypotension in aneurysm surgery minimize brain damage in the exposure of aneurysm and provide accurate isolation of the aneurismal neck from the parent vessel in aneurysmal neck ligation. 4. Proximal ligation of the anterior cerebral artery is also an effective procedure to prevent recurrent hemorrhage from anterior communicating aneurysm.

Background: Intravenous (IV) oxycodone has been used at induction to prevent an intubation reaction. The aims of the current study were to calculate the median effective dose (ED) and the 95% effective dose (ED) of an IV bolus of oxycodone that blunts the hemodynamic response to tracheal intubation with propofol according to gender and to observe the adverse events of induction-dose oxycodone. Methods: Adult patients who required general anesthesia and tracheal intubation were enrolled. Tracheal intubation was performed using unified TD-C-IV video laryngoscopy and an ordinary common endotracheal tube. Dixon's up-and-down method was used to obtain EDdata for women and men separately. The initial dose of oxycodone was 0.2 mg/kg for women and 0.3 mg/kg for men (step size was 0.01 mg/kg). Next, a dose-response curve from the probit analysis was generated to determine the EDand EDto blunt the intubation reaction in female and male patients. Adverse events following oxycodone injection were observed for 5 min before propofol injection. Results: Sixty-three patients were analyzed, including 29 females and 34 males. According to the probit analysis, the ED and EDof oxycodone required to blunt the intubation reaction in women were 0.254 mg/kg (95% confidence interval [CI], 0.220-0.328 mg/kg) and 0.357 mg/kg (95% CI, 0.297-2.563 mg/kg), respectively. In men, the ED and EDwere 0.324 mg/kg (95% CI, 0.274-0.381 mg/kg) and 0.454 mg/kg (95% CI, 0.384-2.862 mg/kg), respectively. Men required 28% more oxycodone than women for induction (P < 0.01). The most common adverse events were dizziness (87.3%), vertigo (66.7%), sedation (74.6%), and respiratory depression (66.7%). Conclusions Oxycodone can be used for induction to prevent intubation reactions. Gender affected the EDand EDof oxycodone for blunting the tracheal intubation reaction.

italic>Acanthopanax senticosus is one of the genuine regional herb in Northeast China. In this study, we identified the germplasm resources of commercial A. senticosus samples based on atpI and atpB_rbcL according to the previous chloroplast genome sequencing results, and determinated the content of syringin by HPLC to evaluated the quality of commercial samples. A total of 80 A. senticosus samples were collected from 47 cities in 24 provinces. DNA was extracted to amplify the products of atpI and atpB_rbcL by PCR. The results showed that 7 haplotypes (H2, H5, H8, H10, H12, H14, H23) were formed by the combined analysis of the two gene fragments. H2 from Yichun in Heilongjiang, Shangzhi in Harbin, Suihua in Heilongjiang, Fushun in Liaoning, Benxi in Liaoning, Changbai in Jilin and Jingyu in Jilin were the dominant genotype, representing 58.75% of the total samples. H14 and H23 were the unique haplotypes of the producing area. It is speculated that the commercial A. senticosus samples with haplotypes of H14 and H23 are from Raohe, Shuangyashan, Heilongjiang and Mingshui, Suihua, Heilongjiang, respectively. HPLC analysis indicated that the content of syringin in 73.96% of the samples met the Pharmacopoeia standards. There was a significant difference in the content of syringin among the samples, ranging from 0.003 7% to 0.524 5%, with a difference of 0.520 8%, indicating that the quality of the samples in the market of A. senticosus was uneven. However, there were no significant differences in the contents of syringin in the commercial A. senticosus among different haplotypes. The content of syringin in the haplotype H23 in the market sample is relatively high, so it may be a germplasm with better quality. This study researched the germplasm resources and medicinal materials quality of commercial A. senticosus samples and will help guide the commercial circulation, reasonable medication of A. senticosus, and the screening of excellent germplasm.
