OBJECTIVETo evaluate the short-term efficacy and safety of Bushen Shuji Granule (BSG) in treating ankylosing spondylitis (AS) patients.

METHODSA prospective randomized controlled clinical trial was carried out in 62 active stage AS patients with Shen deficiency Du-channel cold syndrome (SDDCS), who were randomly assigned to the BSG group (treated with BSG) and the control group (treated with Celecoxib Capsule). Twelve weeks consisted of one therapeutic course. Therapeutic effects were evaluated by ASAS20 and ASAS40 (set by Assessments in Ankylosing Spondylitis working group) , BASDA150, Chinese medical (CM) syndrome efficacy evaluation standards. BASDAI, the Bath Ankylosing Spondylitis Functional Index (BASFI), the Bath AS Metrology Index (BASMI), scores for spine pain, scores for pain at night, patient global assessment (PGA) , erythrocyte sedimentation rate (ESR) , and C reactive protein (CRP) were observed before and after treatment.

RESULTSAfter three-month treatment by BSG, ASAS20 standard rate was 63. 33% (19/30 cases) in the BSG group and 66.67% (20/30 cases) in the control group with no significant difference between the two groups (χ2 = 0.073, P > 0.05). The efficacy for CM syndromes was 70.00% (21/30 cases) in the BSG group, higher than that in the control group [40.00% (12/30 cases), χ2 = 5.455, P < 0.05]. Scores for CM syndromes, BASDAI, night pain index, spinal pain index, PGA, CRP were improved in the BSG group (P < 0.05, P < 0.01). The incidence of adverse events in the BSG group was lower than that of the control group.

CONCLUSIONBSG based on Shen supplementing, Du-channel strengthening, blood activating, and channels dredging method had good short-term clinical efficacy and safety in treating AS.

Metabolomics is an omics subject which studies on the metabolic network of organism and the intrinsic metabolic change of entirety with the aim of clarifying the mechanism of medicinal effect and pathogenesis of disease, is similar to the whole concept theory of Chinese medicine. The mectabolomics technology helps to promote the modern process of traditional Chinese medicine. This article illustrated the application research on the concept of metabolomics, the syndrome of Chinese medicine, quality and components of traditional Chinese medicine, traditional Chinese medicine compounds and so on, explored the problems on the current research and the prospect meanwhile.

AIMTo compare the antagonistic effects of 6 beta-naltrexol and naltrexone against morphine analgesia.

METHODSThe effects of 6 beta-naltrexol and naltrexone against morphine analgesia were observed in mouse heat radiant tail-flick assay and in mouse (55 +/- 1) degrees C hot plate test. The displacement of 6 beta-naltrexol and naltrexone on binding to CHO-mu receptor was observed by radioligand binding study.

RESULTS6 beta-naltrexol antagonized morphine analgesia but the potency was (6.1 +/- 1.7)% that of naltrexone. The effective duration of 6 beta-naltrexol was 3-4 times that of naltrexone and the peak time of the response was about 0.5-1 h after s.c. equivalent efficacy dose (ED95) in two models. Like naltrexone, 6 beta-naltrexol was effective by oral administration and the potency ratio of p.o./s.c. was 1/3. As an antagonist to opioid receptor, the displacement of 6 beta-naltrexol was about 12.5% that of naltrexone, which was almost in agreement with the efficacies against morphine analgesia in mouse.

CONCLUSIONCompared with naltrexone, 6 beta-naltrexol was less potent but duration was longer.

BACKGROUND: Airway management in intensive care unit (ICU) patients is chalenging. The aim of this study was to compare the rate of successful first-pass intubation in the ICU by using the direct laryngoscopy (DL) and that by using the video laryngoscopy (VL). METHODS: A randomized, non-blinded trial comparing first-pass success rate of intubation between VL and DL was performed. Patients were recruited in the period from August 2014 to August 2016. All physicians working at ICU received hands-on training in the use of the video and direct laryngoscope. The primary outcome measure was the first-pass intubation success. RESULTS: A total of 163 ICU patients underwent intubation during the study period (81 patients in VL group and 82 in DL group). The rate of successful first-pass intubation was not significantly different between the VL and the DL group (67.9％ vs. 69.5％,P=0.824). Moreover, the overall intubation success and total number of attempts to achieve intubation success did not differ between the two groups. In patients with successful first-pass intubation, the median duration of the intubation procedure did not differ between the two groups. The Cormack-Lehane grades and the percentage of glottic opening score were similar, and no significant differences were found between the two groups. There were no statistical differences between the VL and the DL group in intubation complications (all P>0.05). CONCLUSION: Among ICU patients requiring intubation, there was no significant difference in the rate of successful first-pass intubation between VL and DL.

OBJECTIVETo construct the cloning vector of glycoprotein G2 gene of hantavirus (HV), to analyze the sequence of G2 gene by the phylogenetic tree, and to study the differences among glycoprotein G2 genes from the world around.

METHODSEnvelope glycoprotein G2 gene was amplified from four specimens of Shandong province by RT-PCR, and the product recombined into the PMD-18T vector. The clones that carry the G2 gene were identified. After sequencing, the gene sequence was handled with the software DNASTAR, compared with 24 strains worldwide and the phylogenetic tree was drawn.

RESULTSHV G2 gene was amplified by RT-PCR from 4 specimens, named GM04-38.G2, ZB8.G2, JUN5-14.G2, RCH5.G2, respectively. The map of the phylogenetic tree showed that all the 4 strains belonged to SEO-type hantavirus. The analysis of the sequence showed that all the four HV strains had the highest rates of homology with Z37 strain. The sequence homology of SEO-type HV strains was from 82.3% to 99.8%.

CONCLUSIONThe four cloning vectors containing the glycoprotein G2 genes were successfully constructed. Envelope glycoprotein G2 gene of four specimens from Shandong province had high homology rates.

OBJECTIVETo study the clinical significance of CD163 in the diagnosis and the evaluation of severity and prognosis of childhood hemophagocytic lymphohistiocytosis (HLH).

METHODSNinety-four children were classified into Epstein-Barr virus (EBV)-positive (n=55) and EBV-negative groups (n=39; control group). The EBV-positive group was subgrouped into infectious mononucleosis (IM; n=47) and HLH (n=8). Serum levels of soluble CD163 were measured using ELISA. Expression of CD163 on mononuclear cells was detected by flow cytometry.

RESULTSThe serum levels of soluble CD163 were>10 000 ng/mL in all eight HLH patients (>30 000 ng/mL in 3 cases). The mean serum levels of soluble CD163 in the HLH group were significantly higher than in the control and IM groups (P<0.05). The serum levels of soluble CD163 in EBV-positive children were positively correlated with EBV-DNA copies and serum levels of ferritin and LDH, but were negatively correlated with white blood cell count, neutrophil count, hemoglobin and platelet count. The follow-up after treatment for three HLH patients showed that serum levels of soluble CD163 were significantly reduced, but the soluble CD163 levels rebounded in one patient who was complicated by fungal pneumonia infection.

CONCLUSIONSThe levels of serum soluble CD163 may be related to the severity in children with HLH. The EBV-positive children with soluble CD163 levels >10 000 ng/mL should be considered the possibility of HLH.
