This article summarized the technique research and application status of near-infrared spectroscopy (NIRS), in order to explore hypoxia,qi-deficiency and their connections with typical symptoms. It also discussed NIRS acquired oxygen saturation (SaO2) and its relevant means and methods for information quantification ofqi-deficiency. The accurate obtained SaO2 value was applied in the association with the strength of chest distress in the subjective sensation due toqi-deficiency. According to current data, the normal value,qi-deficiency degree and uncomfortable degree of subjective sensation among patients of different altitudes and ages were summarized. It can be applied to assist TCM physicians in the quick quantification of qi-deficiency.

Cucumber mosaic virus was detected from infected Basella rubra L. with the indirect enzyme-linked immunosorbent assay. Total RNA was extracted from infected leaves and the cDNAs of coat protein gene of CMV-Ba were obtained by RT-PCR. The amplified cDNA fragments were then cloned into pMD 18-T vector and sequenced,the result showed that the CP gene was 657 nucleotides in length. This sequence was aligned with the obtained CP gene and some CMV strains or isolates of subgroup Ⅰ and subgroup Ⅱ in GenBank using DNA MAN software. The results showed that CMV-Ba shared 90.9%~93.8% and 76.1%~76.9% identity with the known CP genes of subgroup Ⅰ and Ⅱ respectively in nucleotide level,on the other hand,amino acids deduced from CMV-Ba CP gene shared 92.7%~97.7% and 72.4%~78.1% identity with the known CP protein of subgroup Ⅰ and Ⅱ,respectively. This suggested that CMV-Ba CP gene belongs to CMV subgroupⅠ.

Objective · To design and build a high-throughput sequencing approach based on targeted panel sequencing (TPS) using for the primary immunodeficiency disease (PID) diagnosis. Methods · By reviewing the literature and querying the relevant databases to determine the known diseasecausing genes of PID, capture probes using for the TPS were designed and customized for all exons and flanking sequences of these genes. A child suspected with PID was diagnosed by the customized TPS. Results · The PID sequencing panel contains a total of 100 known pathogenic genes. The sequencing data of the patient has 16414298 reads. The average coverage depth is 157 X, 98.35% of the target region sequencing depth is greater than 20 X, and 99.97% of the target region sequencing depth is greater than 1 X. Finally, a heterozygous nonsense mutation was found in the exon 2 of the CXCR4 gene (c.1000C>T, p.Arg334*) in the child. The results of Sanger sequencing confirmed the variation in the child and showed that his parents were wildtype at the corresponding sites, indicating the mutation is de novo. Conclusion · This study established a high-throughput sequencing diagnostic approach for PID, with which a case of WHIM syndrome was successfully diagnosed.

Objective To observe the influence of hIL-10-MSCs on rejection of rat discordant liver xenotransplantation. Methods The model of cavia to rat discordant liver xenotransplantation was established. The rats were randomized into the control group, MSCs group, and hIL-10-MSCs group.The survival time and liver function of each recipient were observed and expression levels of E-Selectin, LFA-1, VCAM-1, and NF-κB determined by RT-PCR and ELISA 24 h after transplantation.Results The survival time was prolonged, liver function improved, and expressions levels of E-Selectin, LFA-1, VCAM-1 and NF-κB were significantly decreased in the hIL-10-MSCs group (P＜0.05).Conclusion hIL-10-MSCs are able to protect transplanted liver and decrease the expression of E-Selectin, LFA-1, VCAM-1, and NF-κB in the liver.

Objective To observe the influence of hIL-10-MSCs on apoptosis of rats subject to discordant liver xenotransplantation. Methods The model of guinea pig to rat discordant liver xenotransplantation was set up. The orthotopic liver transplantation model was established by using modified two-cuff technique. Following groups were designed: control group, MSCs group and hIL-10MSCs group. Before and after operation, the recipients in control group were injected with normal sodium (2 ml) and decaesadril (0.5 ml) ;Those in MSCs group were injected with MSCs (4.0× 106/ml)and decaesadril (0.5 ml); Those in hIL-10-MSCs group were injected with hIL-10-MSCs (4.0 × 106/ ml)and decaesadril (0.5 ml). Twelve h after operation, the livers of recipient were observed by HE staining and electron microscope, and apoptosis of the livers was detected by using TUNEL. The expression levels of hIL-10, caspase-3, Fas and FasL were assayed by Western blot or immunohistochemistry. Results As compared with control group and MSCs group, the pathological changes was alleviated, the expression of IL-10 was significantly increased, the expression of FasL was significantly reduced in hIL-10-MSCs group. The positive area size of Fas and Caspase-3 in hIL-10MSCs group was 11.5 % and 25.1 %, respectively, significantly smaller than those in control group (35.3 % and 70.8 % respectively, P＜0.05. Apoptosis index in hIL-10-MSCs group was 32.5 %,which was significantly lower than in control group (74.1%) and MSCs group (50. 3 % ). ConclusionhIL-10-MSCs can notably decrease apoptosis of the transplanted liver probably by inhibiting theexpression of Fas/FasL.

Objective To observe the effects of hIL-10-MSCs on heterologous T cell prolifera-tion. Methods hlL-10 was cloned by RT-PCR and then hIL-10/pLOX-cwGFPs was construct. The lentivirus was transfected into cavy MSCs and cell culture supernatant was tested for IL-10 protein by ELISA assay. The effects of hIL-10-MSCs on heterologous T cell proliferation were determined by CCK-8. The effect of peripheral blood mononuclearcell secretion IFN-γ was tested by EIASA. Results hIL-10/pLOX-cwGFP were constructed successfully and hIL-10-MSCs cell culture supernatant of IL-10 protein were increased obviously, hIL-10-MSCs could inhibit heterologous T cell proliferation sig-nificantly(P<0.05) but could not induce T cell proliferation (P<0.05). Adding IL-2 could reverse this inhibition(P<0.05), hIL-10-MSCs cell culture supernatant could inhibit peripheral blood mono-nuclearcell secretion IFN-γ. Conclusion hIL-10-MSCs may play an important role in significant im-munosuppression of heterologous T cell proliferation and suppression of secretion IFN-γ by peripheral blood mononuclear cells.

BACKGROUND:Extradural cortical stimulation combines the advantages of repetitive transcranial magnetic stimulation, transcranial direct current stimulation, subdural cortical stimulation and deep brain stimulation, which can significantly improve motor and language function after stroke. OBJECTIVE:To review the theoretical research and clinical application of extradural cortical stimulation for stroke recovery. METHODS:An online retrieval of PubMed database and CNKI database between January 1995 and April 2014 was performed for articles on theoretical research and clinical application of extradural cortical stimulation for stroke recovery, with the key words of“cortical stimulation, extradural motor cortex stimulation, extradural cortical implants, extradural cortical stimulation, stroke, rehabilitation”in English and Chinese. RESULTS AND CONCLUSION:Because of implantable cortical stimulation, the advantage of extradural cortical stimulation is its minimal invasiveness, high accuracy and transdural contact with the brain. For lack of effective treatment for the chronic phase of stroke patients with motor and language dysfunction, extradural cortical stimulation may be a new therapeutic method. Motor and language functional improvement must derive from reactivation of plasticity, local enhancement of perilesional areas, enhancement of network function and inter-hemispheric balance function, and amplification of sensory input.
