ABSTRACT

ObjectiveTo analyze allergen-specific IgE (sIgE) in the serum of patients with allergic diseases, and provide the basis for clinical diagnosis and treatment. MethodsThe serum sIgE of 29 902 patients with allergic diseases in Hangzhou City of Zhejiang Province was detected by ELISA, and the result was analyzed with gender, age, time distribution. ResultsThe positive rate of total IgE (tIgE) in 29 902 patients with allergic diseases was 77.34%. The most common inhaled allergens were dust mite (36.75%), ragweed (11.23%) and tree pollen (9.06%), and the most common food allergens were egg protein (9.90%), milk (8.88%) and crab (4.62%). The positive rate of sIgE in men was higher than that in women. The positive rate of sIgE in people less than 18 years old was higher than that in people more than 18 years old. The positive rates of tree pollen sIgE decreased year by year. Most patients were allergic to one allergen, accounting for 52.52% of the total sIgE positive patients. ConclusionDust mite, ragweed, tree pollens, egg protein and milk are important allergens in Hangzhou. The prevention and treatment of allergic diseases should focus on these allergens. We should understand that the distribution of allergens in different ages and genders is different, so the prevention and treatment should focus on different aspects.

ABSTRACT

Objective To investigate the effects of different stimulation of electroacupuncture on the protein expressions of SOCS1 and SOCS3 in rabbits with acute facial nerve injury; To determine the better stimulation. Methods New Zealand rabbits were treated with special hemostatic forceps for 5 min, and the length of the lesion was about 2.5 cm. The model of facial nerve injury was induced. The experiment was divided into blank group, sham-operation group, model group, and electoracupuncture weak-, medium-, and strong-stimulation group. The model group received no intervention after surgery. After treatment, the damaged facial nerve of each group was intercepted. The protein expressions of SOCS1 and SOCS3 mediated by negative feedback regulation of JAK-STAT were detected by ABC-ELISA. Results Compared with the blank group, the protein expressions of SOCS1 and SOCS3 in the model group increased (P<0.01). Compared with the model group, the protein expressions of SOCS1 and SOCS3 protein in electroacupuncture weak- stimulation group decreased (P<0.01). Conclusion Electroacupuncture can make SOCS1, SOCS3 protein expressions normal for acute facial nerve injury, and acupuncture treatment effect does not increase with the increase of stimulation.

ABSTRACT

Facial nerve injury results in facial muscle movement disorders that interferes with patient's life. Acupuncture is an effective therapy for facial nerve injury, but its mechanism has not been clarified. The evidence supports that acupuncture can accelerate the repair of facial nerve injury by adjusting the electric wave of patient's facial muscle, improving facial blood circulation, and promoting the expression of cell and protein molecule.

ABSTRACT

At present, lung cancer ranks second and first respectively in the incidence and the mortality among malignant tumors. It is urgent to find new effective anti-lung cancer drugs with less side effects and relatively defined mechanisms. Endoplasmic reticulum stress (ERS)-mediated apoptosis pathway is an effective way to promote tumor cell apoptosis; diterpenoid tanshinone (DT), an effective part separated from Salviae Miltiorrhizae Radix et Rhizoma, was found to have an anti-lung cancer effect in previous studies via ERS-induced PERK-EIF2α pathway. In this paper, human lung adenocarcinoma PC9 cell line and nude mouse transplantation tumor model were applied to verify the anti-lung cancer effect of DT in vivo and in vitro, and illuminate the potential mechanism via ERS induced IRE1α/caspase 12 apoptosis pathway. The results showed that in vivo, DT could promote PC9 cell apoptosis in a concentration-dependent manner, up-regulate Bip, IRE1 and TRAF2 protein expressions in tumor tissue, reduce tumor weight and alleviate bodyweight loss. In vitro, DT inhibited the proliferation of PC9 cell line in a concentration-dependent manner, and destroyed the structure of mitochondria in PC9 cell, promoted Bax, IRE1α, Bip, TRAF2 and caspase 12 protein expressions, lower Bcl-2 protein expression in a time-dependent manner. DT shows a good effect on anti-lung cancer both in vivo and in vitro. The mechanism is related to the activation of ERS-induced IRE1α/caspase 12 apoptosis pathway and the promotion of cell apoptosis. ERS-mediated apoptosis pathway may be an important target of DT on anti-lung cancer.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the distribution and change of the causes of fever of unknown origin(FUO).</p><p><b>METHODS</b>The clinical data of 500 inpatients with FUO in our center between December 2003 and June 2014 were retrospectively analyzed. The diagnostic methods,etiologies,and their possible relationship with age,sex,fever duration,and period.</p><p><b>RESULTS</b>Of these 500 FUO patients,452(90.4%)were confirmed to be with fever caused by conditions including infectious diseases [(n=231,46.2%;e.g.tuberculosis(32.9%,76/231)],connective tissue diseases(CTD)(n=99,19.8%),neoplasms(n=58,11.6%),miscellaneous causes(n=64,12.8%). The causes were not identified in 48 cases(9.6%).The proportion of CTD in female patients was significantly higher than that in male patients(26.3% vs. 14.5%,P=0.025),whereas the proportion of neoplasms in male patients was significantly higher than that in female patients(14.5% vs. 8.0%,P=0.001). Infectious diseases was the most common cause in all age groups,CTD ranked the second in the 21-39-year group and 40-59-year group,and neoplasm was the second most coomon cause in the over 60 year group. Thus,the distribution of FUO etiologies significantly differed in different age groups(χ(2)=43.10,P=0.000). The duration of fever in patients with neoplasms [60(28,90)d] was longer than that in patients with infectious diseases [28(21,42)d,Z=-4.168,P=0.000] or CTD [30(21,60)d,Z=-2.406,P=0.016)]. Compared with the level in 2003-2008,the proportion of CTD significantly increased in 2009-2014(13.7% vs. 23.8%,χ(2)=8.598,P=0.003),along with the dicrease of the proportions of infectious diseases,neoplasms and miscellaneous diseases were decreased(all P>0.05).</p><p><b>CONCLUSIONS</b>Infectious diseases(in particular,tuberculosis)remains the major cause of FUO. CTD and neoplasms also play important roles in the development of FUO. The distributions of the FUO etiologies have certain differences in terms of age,sex,duration of fever,and period.</p>

ABSTRACT

To identify Salvia shandongensis and its relatives at molecular level, the psbA-trnH intergenic region of three species including Salvia shandongensis, Salvia miltiorrhiza and S. miltiorrhiza f. alba were amplified and sequenced. Sequences were assembled with CodonCode Aligner. The K2P genetic distances between Salvia shandongensis and its relatives were calculated and UPGMA tree was performed by MEGA5.0. The results indicated that the lengths of psbA-trnH regions of Salvia shandongensis were about 391 bp, while the lengths of psbA-trnH regions of Salvia miltiorrhiza and S. miltiorrhiza f. alba were about 386 bp. The psbA-trnH sequences showed considerable variations between species and thus were revealed as a promising candidate for barcoding of Salvia shandongensis and its relatives. The intra-specific genetic distances of Salvia shandongensis were 0, while the intra-specific genetic distances of Salvia miltiorrhiza and S. miltiorrhiza f. alba were 0.002 and 0.001 respectively. Additionally, the genetic distance of Salvia shandongensis and Salvia miltiorrhiza ranged from 0.034 to 0.04, and the genetic distance of Salvia shandongensis and S. miltiorrhiza f. alba ranged from 0.005 to 0.008, the intra-specific genetic distances of Salvia shandongensis were much smaller than that of Salvia miltiorrhiza and S. miltiorrhiza f. alba; clustering results showed that there were obvious differences between Salvia shandongensis, Salvia miltiorrhiza and S. miltiorrhiza f. alba, which was consistent with morphological characteristics. This study not only firstly provides the scientific basis for establishing the taxonomy position in molecular level and revealing their genetic relationships of S. shandongensis, S. miltiorrhiza and S. miltiorrhiza f. alba; but also provides DNA molecular identification scientific basis for the development of new medicinal plant resources of Salvia shandongensis. Our results suggest that the psbA-trnH intergenic spacer region can be used as a barcoding to identify Salvia shandongensis, Salvia miltiorrhiza and S. miltiorrhiza f. alba.

ABSTRACT

<p><b>BACKGROUND</b>Periodontitis and osteoporosis are one of the frequently encountered diseases in post-menopausal women. Estrogen receptors (ERs) regulated bone metabolism. To investigate the possible effect of ER-alpha (α) gene polymorphisms on bone mineral density (BMD) in pre- and post- menopausal Chinese women with chronic periodontitis (CP), we provided sufficient quantitative information concerning the correlation between ER gene polymorphisms and BMD in periodontitis.</p><p><b>METHODS</b>Sixty-five post-menopausal and eighty pre-menopausal CP women, and sixty post-menopausal healthy individuals were recruited in this study. Genomic DNA was extracted from oral mucosa swab sample of each subject by the Chelex-100 method. Determination of the ER-α polymorphisms was performed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) technique with XbaI and PvuII enzyme. The index for periodontal examination includes clinical attachment loss (CAL) and probing pocket depth (PPD). BMD was measured by dual-energy X-ray absorptiometry (DEXA).</p><p><b>RESULTS</b>There were no significant differences between the ER-α genotypes of PvuII and XbaI and BMD in post-menopausal and pre-menopausal CP patients, respectively (P >0.05). However, there was association between pre- and post-menopausal CP patients at BMD of lumbar spine L2–L4 (P=0.027) and Ward's BMD (P=0.004). Furthermore, the post-menopausal CP women who carried PvuII TT genotype presented significantly lower Ward's BMD than the pre-menopausal CP women (P=0.007), meanwhile, the post-menopausal CP women who carried XbaI AA genotype presented significantly lower spine L2–L4 BMD than the pre-menopausal CP women (P=0.003).</p><p><b>CONCLUSIONS</b>ER-α gene polymorphisms may be a susceptible indicator for BMD variation of lumbar spine L2–L4 and Ward in Chinese pre- and post-menopausal women patients with CP.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To study the mechanism underlying the inhibitory effect of the anti-HIV peptide VIR576 on antigen-specific T cell activation.</p><p><b>METHODS</b>CCK-8 assay was used to investigate the effect of VIR576 on the proliferation of splenocytes of OVA-specific DO11.10 Tg mice in response to chicken OVA. Hemolysis test, hemolysis inhibition assay and fluorescence binding assay were used to investigate the interaction of VIR576 with the transmembrane domain (TMD) of the T cell receptor (TCR).</p><p><b>RESULTS</b>VIR576 inhibited HIV glycoprotein gp41 fusion peptide-mediated antigen specific T cell activation, and VIR576 itself also inhibited splenocyte proliferation in responses to OVA (P<0.05). Hemolysis test, hemolysis inhibition assay and fluorescence binding assay demonstrated that VIR576 suppressed TCR-TMD-mediated hemolysis and competitively inhibited Rho-VIR576 binding to TCR-TMD peptide.</p><p><b>CONCLUSION</b>VIR576 is effective in suppressing the antigen-specific T cell activation via TCR and can interact with TCR-TMD. VIR576 may serve as a potent microbicide candidate to block sexual transmission of HIV due to of its inhibitory effect on both HIV entry and antigen-specific T cell activation.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To identify the overall anatomical characteristics and the clinical value of the lumbar nerves under CT multiplanar reconstruction.</p><p><b>METHODS</b>Fifty normal subjects and 30 patients with LN diseases (51 sides) were selected, including 10 patients with lumber intervertebral disk hernia, eight patients with spinal stenosis, 5 patients with spondylolisthesis, 1 patient with tethered cord syndrome, 1 patient with lumbar scoliosis, and 5 patients with spinal trauma The 16-slice helical CT (Light Speed, GE Company) was used for scanning the lumbar vertebra with multiplanar reconstruction in Workstation (ADW4.1) with UNIX System in DICOM format. The image was set on the same slice for the overall anatomy and manifestations of the lesions.</p><p><b>RESULTS</b>The same-slice imaging showed the strip-like LN slightly lower than the surrounding muscle in density. Each LN went out of the dural sac at an acute angle. The course of the lumbar plexus and its major branches, including the obturator nerve, femoral nerve and reproductive nerve, and their relations to the adjacent structures were clearly revealed. The percentage of the segments displayed was well associated with the reconstruction angle, with the order being oblique coronal > outward-rotated oblique coronal > oblique sagittal > coronal > sagittal section. The major manifestations of abnormal LN included compression and displacement (50 sides, 98.0%), morphological changes (49 sides, 96.1%), adhesion (41 sides, 80.4%).</p><p><b>CONCLUSIONS</b>The CT multiplanar reconstruction is ideal for the imaging of the overall size, shape, running and tension of the LN root; it is valuable in clinical diagnosis.</p>
