ObjectiveTo explore the effect of Qingfei Jiangmai decoction (QJD) on the content of mercapturic acids in urine in healthy people amid PM2.5 (particles 2.5 microns or less in size) pollution. MethodA total of 84 healthy students of 18-30 years old in Beijing were recruited and they were randomized into the test group (42 in total, with 1 dropout) and control group (42 in total, with 3 dropouts). During the pollution, the test group and the control group respectively took QJD granules and placebo for 7 days (1 bag/time, 2 times/day), and another 7-day intervention with the same drugs was performed at an interval of 4 weeks. The time-activity patterns were recorded during the intervention. On-line solid phase extraction-liquid chromatography/tandem mass spectrometry (SPE-LC-MS/MS) was performed to detect the content of PM2.5-related metabolites S-phenylmercapturic acid (SPMA), 3-hydroxypropylmercapturic acid (3-HPMA), 3-hydroxy-1-methylpropylmercapturic acid (HMPMA), N-acetyl-S-(2-nitrile ethyl)-L-cysteine (CEMA), and N-acetyl-S-(2-hydroxy ethyl)-L-cysteine (HEMA) in urine before and after intervention. Statistical analysis was followed. ResultThe content of CEMA, HEMA, 3-HPMA, and HMPMA in the test group was all higher after the intervention than before the intervention, with the significant difference in HEMA (P<0.05). After intervention, content of HEMA and SPMA was significantly higher in the test group than in the control group (P<0.05), and the difference in HEMA (Z=-3.614, P<0.01) and HMPMA (Z=-1.988, P<0.05) before and after invention in the test group was significantly larger than that in the control group. After the intervention, HEMA in the test group was significantly higher than that in the control group (F=7.597, P<0.01). ConclusionDuring PM2.5 pollution, QJD can increase the excretion of HEMA, a metabolite of ethylene oxide, in the urine of healthy people in Beijing, and enhance the detoxification process of toxic components in PM2.5, which is of great value in preventing and treating haze-related illnesses.

Atorvastatin is proven to ameliorate cardiac hypertrophy induced by chronic intermittent hypoxia (CIH).However,little is known about the mechanism by which atorvastatin modulates CIH-induced cardiac hypertrophy,and whether specific hypertrophyrelated microRNAs are involved in the modulation.MiR-31 plays key roles in the development of cardiac hypertrophy induced by ischemia/hypoxia.This study examined whether miR-31 was involved in the protective role of atorvastatin against CIH-induced myocardial hypertrophy.H9c2 cells were subjected to 8-h intermittent hypoxia per day in the presence or absence of atorvastatin for 5 days.The size of cardiomyocytes,and the expression of caspase 3 and miR-31 were determined by Western blotting and RT-PCR,respectively.MiR-31 mimic or Ro 31-8220,a specific inhibitor of protein kinase C epsilon (PKCε),was used to determine the role of miR-31 in the anti-hypertrophic effect of atorvastatin on cardiomyocytes.PKCε in the cardiomyocytes with miR-31 upregulation or downregulation was detected using RT-PCR and Western blotting.The results showed that CIH induced obvious enlargement of cardiomyocytes,which was paralleled with increased atrial natriuretic peptide (ANP),brain natriuretic peptide (BNP),and slow/beta cardiac myosin heavy-chain (MYH7) mRNA levels.All these changes were reversed by the treatment with atorvastatin.Meanwhile,miR-31 was increased by CIH in vitro.Of note,the atorvastatin pretreatment significantly increased the mRNA and protein expression of PKCε and decreased that of miR-31.Moreover,overexpression of miR-31 abolished the anti-hypertrophic effect of atorvastatin on cardiomyocytes.Upregulation and downregulation of miR-31 respectively decreased and increased the mRNA and protein expression of PKCε.These results suggest that atorvastatin provides the cardioprotective effects against CIH probably via up-regulating PKCε and down-regulating miR-31.

Objective To study the directional migration of bone rnarrow-derived stenl cells (BMSCs)towards the glioma and the distribution of tbe migrated BMSCs in the brain. Methods In vitro cultured BMSCs isolated from the bone marrow of male Wistar rats were identified using immunofluorescence technique. and their stem cell properties wcrc assessed by means of induced differentiation in vitro into adipocytes and osteoblasts.Wistar rat models bearing glioma were established by stereotactic injection of C6 glioma cells into the basal ganglia,and 7 days later.Brdu-labeled BMSCs werc injected stereotaetically into the contralateral hemisphere or the contralateral ventricle, or intravenously via the tail vein.The rats were sacrificed 14 days afterthe BMSC injection,and coronal paraffin sections(5 μm thick)of the brain tissue were prepared.HE staining was used to observe the extent of intracranial glioma growth,and the distribution of the BMSCs in the glioma tissue as well as in the brain tissue was identified With immunofluorescent staining. ResuIts The BMSCs implanted into either the contrahteral hemisphere or the contralateral ventricle were found to migrate towards the glioma mostly along the needle tract,and distinct green fluorescence emitted by the labeled BMSCs Was detected on the boundary between the glioma and the normal brain tissue.A few fluorescent BMSCs were also seen around the glioma tissue after intravenous injection of the cells. Conclusion BMSCs injected into the cerebral parenchyma,contralateral ventricle,or the tail vein are capable of directional migration into the glioma tissue,suggesting their potential as a new vehicle for delivering therapeutic genes into the glioma tissue.

OBJECTIVETo identify the candidate auto-antigen of rheumatic heart disease as a molecular marker for this disease.
METHODSThe total RNA of the heart tissue of patients with rheumatic heart disease was extracted and reverse-transcribed into long cDNA to construct the phage expression library. The library was screened using the serum from patients with active rheumatic fever, and the positive clone was identified and analyzed by bioinformatics and expressed in vitro. The expressed products were evaluated with Western blotting and its cross-reactivity was assessed.
RESULTSThe phage expression library of the heart tissue of patients with rheumatic heart disease was constructed, with the titer of the primary library of 3.3×10(6) pfu/ml, recombinant rate of 99%, and 81% of the inserted segments were larger than 1 kb. An auto-antigen RHDAG1 was identified by screening, which was homologous to keratin 18. RHDAG1 was detected in the serum of patients with active rheumatic fever and of those with rheumatic heart disease, but not in the serum of healthy subjects.
CONCLUSIONPhage display library can be an effective strategy to screen the auto-antigens of rheumatic heart disease. The auto-antigen RHDAG1 can be a candidate molecular biomarker of rheumatic heart disease and/or rheumatic fever.

OBJECTIVESTo explore the clinical value of functional neuro-navigation and high-field-strength intraoperative magnetic resonance imaging (iMRI) for the resection of intracerebral gliomas involving eloquent language structures.
METHODSFrom April 2009 to April 2010, 48 patients with intracerebral gliomas involving eloquent language structures, were operated with functional neuro-navigation and iMRI. Blood oxygen level dependent functional MRI (BOLD-fMRI) was used to depict both Broca and Wernicke cortex, while diffusion tensor imaging (DTI) based fiber tracking was used to delineate arcuate fasciculus. The reconstructed language structures were integrated into a navigation system, so that intra-operative microscopic-based functional neuro-navigation could be achieved. iMRI was used to update the images for both language structures and residual tumors. All patients were evaluated for language function pre-operatively and post-operatively upon short-term and long-term follow-up.
RESULTSIn all patients, functional neuro-navigation and iMRI were successfully achieved. In 38 cases (79.2%), gross total resection was accomplished, while in the rest 10 cases (20.8%), subtotal resection was achieved. Only 1 case (2.1%) developed long-term (more than 3 months) new language function deficits at post-operative follow-up. No peri-operative mortality was recorded.
CONCLUSIONSWith functional neuro-navigation and iMRI, the eloquent structures for language can be precisely located, while the resection size can be accurately evaluated intra-operatively. This technique is safe and helpful for preservation of language function.

Objective To analyze the cost-effectiveness of hospital rehabilitation and hospital-family rehabilitation in children with cere-bral palsy. Methods From January to December, 2016, 60 cases of children aged one to three years with cerebral palsy were divided into hospital rehabilitation group and hospital-family rehabilitation group, with 30 cases in each group. The hospital rehabilitation group received rehabilitation of traditional Chinese and Western medicine treatment, including exercise therapy, physical therapy and Chinese Medical ther-apy; while the hospital-family rehabilitation group received family rehabilitation. The Gross Motor Function Measure (GMFM) and Pea-body Developmental Motor Scale-fine Motor (PDMS-FM) were used to evaluate the motor function and fine motor function before and af-ter treatment. Results The GMFM score was higher (t=5.333, P<0.001), and the total medical cost was higher (t=23.614, P<0.001) in the hospital rehabilitation group than in the hospital-family rehabilitation group. However, the cost of medical care was significantly lower for every 1-point increase in GMFM and visual-motion integration of PDMS-FM in the hospital rehabilitation group than in the hospital-family rehabilitation group (t>2.065, P<0.05). Conclusion The hospital rehabilitation model may be a more economical and effective treatment for younger age children with cerebral palsy, and the hospital-family rehabilitation model could be used as an effective complementary rehabili-tation model for this age group.
