This study was aimed to discuss the anti-inflammatory and immunization properties ofRe-Du-Ning (RDN) injection in the treatment of acute exacerbation of chronic obstructive pulmonary disease (AECOPD) with phlegm-heat stagnated in the lung syndrome. A total of 110 in-patients were collected from January 2012 to December 2013. Cases were randomly divided into the treatment group (basic treatment plan + 20 ml RDN injection + 250 mL of 5% GS injection, once a day, intravenous injection) and the control group (basic treatment plan + 20 ml of 0.9% NS injection + 250 mL of 5% GS injection, once a day, intravenous injection), with 55 cases in each group. The treatment course was 14 days. Observations were made on traditional Chinese medicine (TCM) symptom score, clinical effect, blood routine examination, blood gas analysis and T lymphocyte subgroups before and after the treatment in both groups. The results showed that in the aspects of TCM symptom score and clinical effect, the posttreatment TCM symptom score and total integration in the treatment group were obviously improved compared to the control group except for shortness of breath, dry mouth and thirsty, flushing (P < 0.05). The total effective rate was obviously better than that of the control group. In the aspect of anti-inflammation, the total white blood cell (WBC) count and the normal neutrophil percentage of both pretreatment and posttreatment in the treatment group were obviously decreased compared to pretreatment (P < 0.05). However, there were no statistical differences on WBC count and normal neutrophil percentage compared to posttreatment in the control group. In the aspect of blood gas analysis, the posttreatment PaCO2 and PaO2 of the treatment group were obviously better than the control group (P < 0.05). In the aspect of immune regulation, the posttreatment T lymphocyte subgroups CD3+ and CD4+ of the treatment group were higher than the control group. The expression inhibition / cytotoxic lymphocyte (CD8+) was obviously lower than the control group (P < 0.05). The CD4+ / CD8+ was back to the normal reference level. It was concluded that in the treatment of AECOPD with phlegm-heat stagnated in the lung syndrome, on the basis of western medicine symptomatic treatment plan, RDN injection was assisted to clear heat, relieve toxin and remove phlegm. It can obviously improve patient’s clinical symptoms and increase the clinical therapeutic effects. The treatment was especially targeted to infection-induced respiratory failure patients combined low immunity with possible identified therapeutic effects.

The gradient bioceramics coating was prepared on the surface of Ti-6Al-4V alloy by using wide-band laser cladding. And the effect of technological parameters of wide-band laser cladding on microstructure and sinterability of gradient bioceramics composite coating was studied. The experimental results indicated that in the circumstances of size of laser doze D and scanning velocity V being fixed, with the increasement of power P, the density of microstructure in bioceramics coating gradually degraded; with the increasement of power P, the pore rate of bioceramics gradually became high. While P = 2.3 KW, the bioceramics coating with dense structure and lower pore rate (5.11%) was obtained; while P = 2.9 KW, the bioceramics coating with disappointing density was formed and its pore rate was up to 21.32%. The microhardness of bioceramics coating demonstrated that while P = 2.3 KW, the largest value of microhardness of bioceramics coating was 1100 HV. Under the condition of our research work, the optimum technological parameters for preparing gradient bioceramics coating by wide-band laser cladding are: P = 2.3 KW, V = 145 mm/min, D = 16 mm x 2 mm.

The complete genome of encephalomyocarditis virus (EMCV)strain GXLC isolated from swine was sequenced and analyzed. Five overlapped gene fragments covering the entire open reading frame (ORF) were amplified by RT-PCR, and the 3'-untranslated region (UTR) and 5'-UTR were amplified by the 3'-rapid amplification of cDNA ends (RACE) and 5'-RACE method, respectively. The genome sequences of strain GXLC were obtained by assembling the sequences of RT-PCR-generated cDNA fragments. The length of the complete genome was 7 725 nucleotides (nt). The homology comparison and phylogenetic analysis of the nucleotide and deduced amino acid sequences between strain GXLC and other EMCV strains available in GenBank were performed. The results showed that the complete genome identity between GXLC strain and the strains from China, i.e. GX0601, GX0602, BJC3 and HB1 and the strains from other countries, i.e. CBNU, K3, K11, TEL-2887A, EMCV-R and PV21 was over 99%. The phylogenetic trees based on the complete genome, the structural protein or the non-structural protein gene sequences revealed that the tree topology was similar. All the EMCV strains could be divided into two groups: group I and group II, and group I could be subdivided into subgroup Ia and subgroup Ib. The strains from swine belonged to subgroup Ia or Ib, and the strains from mice belonged to subgroup Ia, while the strains from Sus scro fa belonged to group II. Strain GXLC, together with other EMCV isolates from China, belonged to subgroup Ia.

Objective To study the surgical treatment and effects of the lesions in the third ventricle. Methods The data of 15 patients with third ventricular lesion, accepted surgical treatment were retrospectively analyzed. The lesions were removed through transcallosal approach in 11 patients, frontal trans-cortical approach in 2 and trans-terminalis approach in 2,respectively. Postoperative radiotherapy was performed in 5 and chemotherapy in 2. VP shunt was performed in 1. Results The lesions were total-resected in 8 (53.3%), subtotal-resected in 5 (33.3%) and partial-resected in 2 (13.3%) with 1 postoperative death. The hydrocephalus were resolved in all cases. With a follow-up of 3 to 12 months, all the 14 patients recovered without obvious neurological deficits. Conclusion Proper microsurgical approach and perfect surgical skills are the keys to high resection and good prognosis. And postoperative radiotherapy or chemotherapy may be helpful in improving the outcome

OBJECTIVEThrough reviewing the relevant literature from the past decades, to summarize the assessment and management of fractures of the clavicle, and provide an overview of the clinical results of a range of treatment options.

DATA SOURCESThe data analyzed in this review are mainly from articles included in PubMed and EMBASE, published from 1960 to 2015.

STUDY SELECTIONStudies involving assessment of fractures of the clavicle were reviewed. Further literatures were gathered regarding the conservative and surgical treatment of these fractures, including the methods of fixation and the surgical approaches used. Both conservative and surgical treatments were then compared and contrasted.

RESULTSThrough retrieving and reading the abstract, a total of 42 representative articles were selected, which covered all aspects of the conservative treatment and surgical treatment, and compared the advantages and disadvantages of different treatment options.

CONCLUSIONSAlthough the majority of recent data suggest that surgery may be more appropriate as it improves functional outcome and reduces the risk of complications, we recommend that the treatment should be individually assessed.

Objective:To investigate the clinical characteristics of carotid webs and prevention measurements of cerebral ischemic stroke caused by carotid webs.Methods:The clinical data of three patients with carotid webs admitted to our hospital from October 2017 to January 2019 were retrospectively studied, and publications (208 patients with carotid webs) reported from January 1, 2014 to June 30, 2019 in PubMed, Embase, Wanfang and CNKI databases were collected. The demographic and clinical characteristics of carotid webs and secondary prevention measurements of ischemic stroke caused by carotid webs were analyzed.Results:A total of 211 patients with carotid webs were enrolled, including 68 male (32.2%) and 143 female (67.8%), with an median age of 48 years. Prevalence of risk factors for cerebrovascular disease reported in 148 patients was as follows: hypertension ( n=43, 29.1%), dyslipidemia ( n=19, 12.8%), diabetes mellitus ( n=14, 9.5%), and smoking ( n=12, 8.1%); 89.8% of carotid webs(44/49) caused mild stenosis of carotid artery (stenosis degree<50%). In secondary stroke prevention, the recurrence rate of stroke patients treated with anticoagulation plus antiplatelet was obviously lower than that of patients treated with antiplatelet alone (11.1% vs. 49.3%). No ischemic stroke or surgical complications were noted in 23 patients underwent carotid endarterectomy and 54 patients underwent carotid stent implantation during the mean follow-up period of 12 months (one-60 months) and 11 months (3-144 months), respectively. Conclusions:Carotid web may be a vital risk factor for cryptogenic stroke. Anticoagulation plus antiplatelet is superior to antiplatelet alone in preventing stroke recurrence. Carotid endarterectomy and carotid stent implantation may be the perfect choices for carotid web patients with high risk of stroke recurrence.

Objective::To explore the pharmacological mechanism of Xiao Xianxiongtang in treating type 2 diabetes mellitus (T2DM) by network pharmacology. Method::The main active ingredients, corresponding targets and target genes of Xiao Xianxiongtang were searched on Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) website. Relevant target genes of T2DM were obtained through Gene Cards. The targets of drug active ingredients were mapped to the targets of T2DM, and the intersection targets were obtained as the predictive targets of Xiao Xianxiongtang on T2DM. Cytoscape 3.7.1 software was used to construct the drug active ingredient-intersection target network model and select the key active ingredients. Interactive protein-protein interaction network (PPI) was constructed by STRING website, and key target genes were selected. Gene function analysis (GO) and enrichment analysis based on the Kyoto encyclopedia of genes and genomes (KEGG) pathway were performed on the intersecting targets using DAVID6.8 online tool. Result::Xiao Xianxiongtang had 30 active ingredients, 156 relevant targets, 14 key active ingredients and 18 key target genes on T2DM. GO analysis showed that the biological functions of Xiao Xianxiongtang in the treatment of potential genes of T2DM mainly involved transcriptional regulation, oxidative stress, protein binding and inflammatory reaction. KEGG pathway enrichment showed that the main pathways of Xiao Xianxiongtang in the treatment of T2DM were hypoxia inducible factor-1 (HIF-1) signaling pathway, tumor necrosis factor (TNF) signaling pathway, Toll-like receptor signaling pathway and thyroid hormone signaling pathway, phosphatidylinositol 3 kinase/protein kinase B (PI3K/Akt) signaling pathway, hepatitis B, hepatitis C, tyrosine kinase receptor2(ErbB) signaling pathway, calcium signaling pathway and nuclear factor-kappa B (NF-κB) signaling pathway. Conclusion: Xiao Xianxiongtang is a multi-component, multi-target and multi-pathway process in the treatment of T2DM. It plays an important role in the treatment of T2DM by regulating transcription, oxidative stress, protein binding and inflammatory reaction. Conclusion::The mechanism of Xiao Xianxiongtang in treating T2DM may alleviate insulin resistance, increase insulin sensitivity and reduce blood sugar by inhibiting the secretion of inflammatory factors, participating in anti-inflammatory response, reducing oxidative stress, increasing intracellular calcium concentration, blocking glucagon signaling pathway and activating PI3K/Akt pathway.
