ABSTRACT
Poria is an important medical herb in clinic. The authors isolated a polysaccharide(PCP-Ⅰ) from Poria in previous studies, which is composed of galactose, mannose, fucose and glucose. PCP-Ⅰ exhibited significant adjuvant effects on H1N1 influenza vaccine, hepatitis B surface antigen and anthrax protective antigen, and its adjuvant activity was stronger than aluminium adjuvant. However, little is known about the chemical structure of PCP-Ⅰ at present. In this study, weak acid hydrolysis was used to obtain the backbone oligosaccharide of PCP-Ⅰ. Then periodate oxidation, Smith degradation, methylation analysis, Fourier transform infrared spectroscopy(FT-IR), nuclear magnetic resonance(NMR) and gas chromatography-mass spectrometry(GC-MS) were performed to investigate the chemical structural features of PCP-Ⅰ and its hydrolytic oligosaccharide(PCP-Ⅰ-hy-1). These results suggested that the backbone of PCP-Ⅰ was composed of galactose with α anomeric carbon and β anomeric carbon. The linking residues of galactan are(1→),(l→6) and(1→2,6).

ABSTRACT
Objective: To observe the clinical efficacy of spleen-invigorating and qi-benefiting pediatric massage (tuina) for treating recurrent respiratory tract infection in children with cerebral palsy due to qi deficiency of spleen and lung. Methods: A total of 70 children with cerebral palsy who suffered from recurrent respiratory tract infection due to qi deficiency of spleen and lung were randomized into an observation group and a control group by the random number table method, with 35 cases in each group. Both groups were treated with conventional rehabilitation training, while the observation group was given additional spleen-invigorating and qi-benefiting pediatric massage, and the control group additionally took oral Yu Ping Feng granule. The clinical efficacy was evaluated by the total effective rate, traditional Chinese medicine (TCM) symptom score, and serum levels of immunoglobulin (Ig) A, IgM and IgG. Results: The difference in total effective rate between the two groups after treatment was statistically significant (P<0.05). After treatment, the TCM symptom scores in both groups decreased to varying degrees than those before treatment, and the intra-group differences were statistically significant (all P<0.01); the differences in the scores of various TCM symptoms between the two groups were statistically significant (all P<0.05). After treatment, the levels of IgA, IgM and IgG of the children in both groups increased to varying degrees, and the intra-group differences were statistically significant (all P<0.05). The between-group differences in the IgA, IgM and IgG levels after treatment were statistically significant (all P<0.05). Conclusion: Spleen-invigorating and qi-benefiting pediatric massage can effectively treat recurrent respiratory tract infection due to qi deficiency of spleen and lung in children with cerebral palsy, relieve the clinical symptoms and improve immune function, and thus is worthy of clinical promotion and application.
ABSTRACT
BACKGROUND@#Hyperbaric oxygen treatment (HBOT) has been demonstrated to influence the keloid recurrence rate after surgery and to relieve keloid symptoms and other pathological processes in keloids. To explore the mechanism of the effect of HBOT on keloids, tumor immune gene expression and immune cell infiltration were studied in this work.@*METHODS@#From February 2021 to April 2021, HBOT was carried out on keloid patients four times before surgery. Keloid tissue samples were collected and divided into an HBOT group (keloid with HBOT before surgery [HK] group, n = 6) and a non-HBOT group (K group, n = 6). Tumor gene expression was analyzed with an Oncomine Immune Response Research Assay kit. Data were mined with R package. The differentially expressed genes between the groups were compared. Hub genes between the groups were determined and verified with Quantitative Real-time PCR. Immune cell infiltration was analyzed based on CIBERSORT deconvolution algorithm analysis of gene expression and verified with immunohistochemistry (IHC).@*RESULTS@#Inflammatory cell infiltration was reduced in the HK group. There were 178 upregulated genes and 217 downregulated genes. Ten hub genes were identified, including Integrin Subunit Alpha M (ITGAM), interleukin (IL)-4, IL-6, IL-2, Protein Tyrosine Phosphatase Receptor Type C (PTPRC), CD86, transforming growth factor (TGF), CD80, CTLA4, and IL-10. CD80, ITGAM, IL-4, and PTPRC with significantly downregulated expression were identified. IL-10 and IL-2 were upregulated in the HK group but without a significant difference. Infiltration differences of CD8 lymphocyte T cells, CD4 lymphocyte T-activated memory cells, and dendritic resting cells were identified with gene CIBERSORT deconvolution algorithm analysis. Infiltration levels of CD4 lymphocyte T cell in the HK group were significantly higher than those of the K group in IHC verification.@*CONCLUSION@#HBOT affected tumor gene expression and immune cell infiltration in keloids. CD4 lymphocyte T cell, especially activated memory CD4+T, might be the key regulatory immune cell, and its related gene expression needs further study.

ABSTRACT
Objective@#Recent studies have shown the important influence of various micro factors on the general biological activity and function of endothelial cells (ECs). Vascular endothelial growth factor (VEGF) and angiogenin (ANG) are classic micro factors that promote proliferation, differentiation, and migration of ECs. The underlying pathophysiological mechanisms and related pathways of these micro factors remain the focus of current research.@*Data sources@#An extensive search was undertaken in the PubMed database by using keywords including "micro factors" and "endothelial cell." This search covered relevant research articles published between January 1, 2007 and December 31, 2018.@*Study selection@#Original articles, reviews, and other articles were searched and reviewed for content on micro factors of ECs. Results: VEGF and ANG have critical functions in the occurrence, development, and status of the physiological pathology of ECs. Other EC-associated micro factors include interleukin 10, tumor protein P53, nuclear factor kappa B subunit, interleukin 6, and tumor necrosis factor. The results of Gene Ontology analysis revealed that variations were mainly enriched in positive regulation of transcription by the RNA polymerase II promoter, cellular response to lipopolysaccharides, negative regulation of apoptotic processes, external side of the plasma membrane, cytoplasm, extracellular regions, cytokine activity, growth factor activity, and identical protein binding. The results of the Kyoto Encyclopedia of Genes and Genomes analysis revealed that micro factors were predominantly enriched in inflammatory diseases.@*Conclusions@#In summary, the main mediators, factors, or genes associated with ECs include VEGF and ANG. The effect of micro factors on ECs is complex and multifaceted. This review summarizes the correlation between ECs and several micro factors.

ABSTRACT
Objective To investigate the physicochemical properties and immunomodulatory activities of crude polysaccharides and their fractions from Sophorae Flavescentis Radix. Methods The crude polysaccharide (SFP-100) was obtained successively by boiling Sophorae Flavescentis Radix in water, ethanol precipitating, dialyzing and freeze drying. SFP-100 was separated withDEAE-cellulose column to obtain three fractions, and these fractions were fruther separated with Sephadex G-100 column to obtain their sub-fractions. The sugar content was determined by phenol-sulfuric acid method, the molecular distribution was determined with gel filtration chromatography, and the monosaccharide composition was analyzed with capillary electrophoresis after PMP derivatization. The immunobiological activities were estimated by measuring the proliferation of mouse spleen lymphocytes as well as the IFN-secretion in mouse splenocytes and the TNF-α secretion in mouse peritoneal macrophages. Results The yield of SFP-100 from Sophorae Flavescentis Radix was 4.83％ and sugar content was 71.62％. SFP-100 was separated into three fractions SFP-100-A, SFP-100-B and SFP-100-C, whose yields were 3.5％, 25.6％ and 16.7％, and the sugar content was 85.99％, 72.09％ and 24.30％, respectively.The monosaccharide composition and their molar ratio for SFP-100-A, SFP-100-B and SFP-100-C were Ara∶Glc∶Gal=7.16∶91.02∶1.82, Xyl∶Ara∶Glc∶Rha∶Gal∶GalA=0.05∶1.00∶0.85∶0.04∶0.35∶0.43, and Xyl∶Ara∶Glc∶Rha∶Gal∶GlcA∶GalA=0.20∶1.00∶0.33∶0.36∶0.45∶0.55∶14.37, respectively. SFP-100-B was further separated into two sub-fractions SFP-100-B-a and SFP-100-B-b with Sephadex G-100, and the other two sub-fractions SFP-100-C-a and SFP-100-C-b were also obtained with the same Sephadex G-100 from SFP-100-C. SFP-100-B-a showed a main wide peak, which had the relative molecular weight 1.02×105 and monosaccharide composition Ara∶Glc∶Rha∶Gal = 1.00∶0.06∶0.02∶0.29. Meanwhile, the relative molecular weight and monosaccharide composition were 5.43×104 and Xyl∶Glc =1.00∶3.81 for the main peak of SFP-100-C-a, and 2.75×104 and Ara∶Glc∶Rha∶Gal∶GlcA∶GalA=1.00∶2.10∶0.57∶0.74∶1.09∶33.75 for the main peak of SFP-100-C-b, respectively. The crude polysaccharides SFP-100 and its fractions, SFP-100-B and SFP-100-C, as well as the sub-fractions, SFP-100-B-a, SFP-100-B-b and SFP-100-C-a, increased the proliferation of spleen cells, all in a dose-dependent manner. Further, SFP-100 could improve the secretion of IFN-γ and TNF-α in spleen cells, while SFP-100-B, SFP-100-C, SFP-100-B-a and SFP-100-B-b could stimulate the secretion of IFN-γ. Conclusion The crude polysaccharides of Sophorae Flavescentis Radix and their fractions showed a good immunomodulatory activity, which may be related to the clinical use of Sophorae Flavescentis Radix for the anti-HBV and anti-inflammatory therapy.

ABSTRACT
The antisense transcript long non-coding RNA (1ncRNA) (antisense non-coding RNA in the INK4 locus,ANRIL) is an antisense of the cyclin-dependent kinase inhibitor 2B (CDKN2B) gene on chromosome 9p21 that contains an overlapping 299-bp region and shares a bidirectional promoter with alternate open reading frame (ARF).In the context of gene regulation,ANRIL is responsible for directly recruiting polycomb group (PcG) proteins,including polycomb repressive complex-1 (PRC-1) and polycomb repressive complex-2 (PRC-2),to modify the epigenetic chrornatin state and subsequently inhibit gene expression in cis-regulation.On the other hand,previous reports have indicated that ANRIL is capable of binding to a specific site or sequence,including the Alu element,E2F transcription factor 1 (E2F1),and CCCTC-binding factor (CTCF),to achieve trans-regulation functions.In addition to its function in cell proliferation,adhesion and apoptosis,ANRIL is very closely associated with atherosclerosis-related diseases.The different transcripts and the SNPs that are related to atherosclerotic vascular diseases (ASVD-SNPs) are inextricably linked to the development and progression of atherosclerosis.Linear transcripts have been shown to be a risk factor for atherosclerosis,whereas circular transcripts are protective against atherosclerosis.Furthermore,ANRIL also acts as a component of the inflammatory pathway involved in the regulation of inflammation,which is considered to be one of the causes of atherosclerosis.Collectively,ANRIL plays an important role in the formation of atherosclerosis,and the artificial modification of ANRIL transcripts should be considered following the development of this disease.
ABSTRACT
Objective: To investigate the relationship between genetic factor and prostate cancer (Pca) risk and the possible cause in it. Methods: The polymorphisms of cytochrome P450 family 17 (CYPl7) rs743572, p27 V109G and androgen receptor (AR) gene CAG repeat length in peripheral blood from 70 cases and 70 controls were detected through the polymerase chain reaction-restriction fragment length polymorphism technique or short tandem repeat-polymerase chain reaction technique. Then, according to the results of case-control study, the recombinant plasmids containing the wild/mutant p27 gene were constructed and transfected Pca LNcap cells. After 24 and 72 h of transfection, the cell proliferative activity was determined by MTT method, cell cycle distribution and apoptosis was detected by flow cytometry, and the expression level of bcl-2, caspase-3 and p27 protein was determined by Western-blot. Results: In three target polymorphisms, only p27 V109G polymorphism was related to Pca risk (P = 0.030, OR = 0.202, 95% CI = 0.042-0.973). Pca risk of p27-109G allele was lower than -109V allele (P = 0.006, OR = 0.285, 95% CI = 0.110-0.737). Cells transfected with wild/mutant p27 gene both showed the higher cells apoptosis rate and the lower cell proliferative activity than mock cells (P < 0.05 or 0.01), the regulatory effect of mutant p27 on cell proliferation and apoptosis was stronger than the wild p27 (P < 0.05). Conclusions: p27-109G allele that could cause higher p27 protein expression than -109V allele in LNcap cells, maybe is the protective factor of Pca.

ABSTRACT
<p><b>BACKGROUND</b>The double kissing (DK) crush technique is a modified version of the crush technique. It is specifically designed to increase the success rate of the final kissing balloon post-dilatation, but its efficacy and safety remain unclear.</p><p><b>METHODS</b>Data were obtained from the DKCRUSH-I trial, a prospective, randomized, multi-center study to evaluate safety and efficacy. Post-procedural and eight-month follow-up intravascular ultrasound (IVUS) analysis was available in 61 cases. Volumetric analysis using Simpson's method within the Taxus stent, and cross-sectional analysis at the five sites of the main vessel (MV) and three sites of the side branch (SB) were performed. Impact of the bifurcation angle on stent expansion at the carina was also evaluated.</p><p><b>RESULTS</b>Stent expansion in the SB ostium was significantly less in the classical crush group ((53.81 ± 13.51)%) than in the DK crush group ((72.27 ± 11.46)%) (P = 0.04). For the MV, the incidence of incomplete crush was 41.9% in the DK group and 70.0% in the classical group (P = 0.03). The percentage of neointimal area at the ostium had a tendency to be smaller in the DK group compared with the classical group ((16.4 ± 19.2)% vs. (22.8 ± 27.1)%, P = 0.06). The optimal threshold of post-procedural minimum stent area (MSA) to predict follow-up minimum lumen area (MLA) < 4.0 mm(2) at the SB ostium was 4.55 mm(2), yielding an area under the curve of 0.80 (95% confidence interval: 0.61 to 0.92).</p><p><b>CONCLUSION</b>Our data suggest that the DK crush technique is associated with improved quality of the final kissing balloon inflation (FKBI) and had smaller optimal cutoff value of post-procedural MSA at the SB ostium.</p>

<p><b>OBJECTIVE</b>To evaluate risk factors and clinical outcome of coronary artery aneurysms (CAA) developed after drug-eluting stent implantation evidenced by coronary angiographic follow-up.</p><p><b>METHODS</b>This study analyzed 4500 consecutive patient with de novo coronary artery stenosis receiving drug-eluting stent (DES) implantation from January 2004 to May 2009. Seven hundred and sixty patients with angiographic follow-ups at 6 - 8 months and 28 - 48 months after the index procedure were enrolled. CAA was defined as a localized dilatation exceeding 1.5 times the diameter of the adjacent artery. The independent risk factors and major adverse cardiac events (MACE) including cardiac death, myocardial infarction, target-vessel revascularization (TVR) and in-stent thrombosis were analyzed.</p><p><b>RESULTS</b>CAA was detected in 70 patients with 70 lesions (9.2%, 70/760). Logistic analysis showed that lesion in an infarct-related artery (OR: 5.9, P < 0.01), lesion in the left anterior descending artery (OR: 4.5, P < 0.01), lesion with chronic total occlusion (OR: 3.4, P < 0.05), and lesion length > 33 mm (OR: 2.9, P < 0.05) were independent risk factors for CAA. Follow-up duration was (1131 ± 478) days. MACE was found in 19 patients and all received TVR. There were 11 patients with myocardial infarction and 8 patients with evidence of in-stent thrombosis. Mortality was zero during follow-up.</p><p><b>CONCLUSIONS</b>The risk factors for the development of CAA after DES are lesions in an infarct-related artery, in the left anterior descending artery, with chronic total occlusion, and with lesion length > 33 mm. MACE is not uncommon in patients with CAA and long-ferm clinical follow-up is warranted for patients with CAA.</p>

<p><b>OBJECTIVE</b>To observe the effects of Qiangjing Capsule (QC) on the oxidative amd antioxidative system in the epididymis of varicocele rats in comparison with those of Shaofuzhuyu Capsule (SC) and Wuziyanzong Capsule (WC), and to explore its possible mechanism of enhancing epididymal sperm maturation.</p><p><b>METHODS</b>Ten of 100 adolescent male SD rats were randomized to a sham-operation group, and varicocele models were successfully established in 72 of the other 90 by narrowing of the left renal vein. Then the model rats were equally assigned to 6 groups: model control, high-dose QC (0.216 g/ml), medium-dose QC (0.108 g/ml), low-dose QC (0.054 g/ml), SC (0.146 g/ml), and WC (0.130 g/ml). After 4 weeks of treatment, we determined the activity of glutathione peroxidase (GPx) and the level of malondialdehyde (MDA) in the left epididymis of different groups of rats.</p><p><b>RESULTS</b>Compared with the sham-operation group, the model group showed a significant decrease in GPx activity (P < 0.01) and a marked increase in the MDA level (P < 0.05). And the high-dose QC group exhibited a significantly hither GPx activity and lower MDA level than all the other groups (P < 0.01 and P < 0.05).</p><p><b>CONCLUSION</b>Varicocele can reduce the activity of GPx and elevate the level of MDA in the epididymis of rats, while Qiangjing Capsule can increase the former and decrease the latter, and thereby may improve epididymal microenvironment, enhance epididymal sperm maturation and promote fertility.</p>
