C8orf32 is a gene which has not been functionally characterized,the mRNA level of this gene is significantly higher in breast cancer tissues than that in normal breast tissues.The amplified cDNA fragment was inserted into the pGEX-6P1 vector fused with the upstream GST gene.The expression vector was transformed into the E.coli BL21(DE3) strain and expression of GST-C8orf32 fusion protein was induced by IPTG..After removal of GST tag by site-specific protease,the C8orf32 protein fused with an eight amino acid peptide tag was obtained.The purity of recombinant C8orf32 protein was about 95%.The identity of the purified protein was confirmed by N-terminal sequencing and tandem mass spectrometry.The polyclonal antibody was prepared by immunizing the New Zealand white rabbits with C8orf32 protein.The polyclonal antibody was proved to recognize the C8orf32 protein correctly.The purified C8orf32 protein can be used for structural and functional studies and the polyclonal antibody can be used for tissue specific protein expression profiling.

OBJECTIVETo observe effects of Ligustrazine on serum S100p protein and neuron-specific enolase (NSE) in elderly patients undergoing orthopedics operations.
METHODSTotally 60 patients undergoing selective total hip replacement, 65-80 years old, who were in line with American Society of Anesthesiologists (ASA) grade I or II, were randomly assigned to the Ligustrazine group (Group L) and the normal saline control group (Group S). The right internal jugular vein catheters were placedcephalad and ensured theirs tips in jugular venous bulbs after anesthesia induction and tracheal intubation. Patients in Group L received 2 mg/kg Ligustrazine Injection (40 drops within one minute) and those inGroup S received equal volume of normal saline via central veins before operations. Other medicines were the same for all patients during and after operation. Five millimeter blood sample was collected frominternal jugular venous bulbs before operation (T0), 24 h (T1), 72 h (T2), 168 h (7th day, T3) after operation. Serum was collected after centrifuge. S100β protein and NSE concentration were analyzed usingELISA. Mini-mental state examinations (MMSE) were scored by the same doctor at T0, T1, T2, and T3,respectively.
RESULTSThere was no statistical difference in MMSE scores, serum S1000 protein, or NSE at TO (P > 0.05). Compared with TO, S100 P protein and NSE concentration increased and MMSE scores decreased at T1, T2, and T3 in the two groups. All indices except S100P protein and NSE at T3 were statistically different between Group L and Group S (P < 0.05).
CONCLUSIONSerum S100P protein and NSE could be changed by pre-operation injecting Ligustrazine at certain dose in elderly patients undergoing orthopedics operations.

OBJECTIVETo study the chemical components of the essential oil of the Semen Sinapis with the different processing methods.
METHODThe essential oils of the crude Semen Sinapis and the roasted Semen Sinapis were extracted by steam distillation. The chemical components were analyzed by means of GC-MS-DS. The relative content of each component was calculated by area normalization.
RESULTThe main chemical components of the essential oil of the crude Semen Sinapis and the roasted Semen Sinapis were similar. The main chemical components were allyl isothiocyanate and 4-isothio-cyanato-1-butene. The chemical components of the essential oil of the crude Semen Sinapis were more than that of the roasted Semen Sinapis.
CONCLUSIONThe effect of different processing methods on the chemical components of the essential oil of Semen Sinapis was significant. Certain chemical components such as isothiocyanato-containing substances, were found in the crude Semen Sinapis.

ObjectiveTo investigate the value of 18F-FDG SPECT myocardial imaging in evaluating haemodynamic change,treatment outcome and prognosis for idiopathic pulmonary arterial hypertension (IPAH).MethodsAll 24 patients with IPAH underwent 18 F-FDG SPECT myocardial imaging.Right ventricle/left ventricle (RV/LV)-FDG uptake was calculated by ROI method drawing over the central areas of left and right ventricular free walls.All patients underwent right heart catheterization within 3 days after imaging studies.Mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) were recorded.After six month pharmaceutical treatment,15 IPAH patients were re-examined with 18F-FDG SPECT myocardial imaging followed by repeated right heart catheterization within 3 days.Plasma N-terminal pro-brain naturetic peptide (NT-proBNP) and endothelin-1 ( ET-1 ) were measured in 17 patients using electrochemiluminescent immunoassay and enzyme immunoassay respectively.All patients were followed up for 12 months at least.Correlations between RV/LV-FDG uptake and mPAP and PVR were determined by simple linear regression analysis.Change of RV/LV-FDG before and after treatment was calculated using Student's t-test.Survival in groups with RV/LV FDG uptake ≥ 1.15 and RV/LV-FDG uptake < 1.15 were compared using Log-rank test.ResultsSignificant correlations were found between RV/LV-FDG uptake and mPAP (r =0.562,P < 0.01 ),and between RV/LV-FDG uptake and PVR ( r =0.574,P < 0.01 ).There were no significant correlation between RV/LV-FDG uptake and NT-proBNP( r =0.18 1,P > 0.05 ),but a significant correlation between RV/LV-FDG and ET-1 was observed (r =0.669,P < 0.01 ).The RV/LV-FDG uptake in patients with positive treatment outcome ( n =6) decreased from 1.38 ± 0.52 to 0.92 ±0.26 (t =4.018,P < 0.05) after 6 months treatment.In contrast,no significant change of RV/LV-FDG uptake was seen in those patients (n =9) with negative treatment outcome ( t =1.861,P > 0.05 ).The mean follow-up time was (21 ±8) months.Mean survival time for the patients with RV/LV- FDG uptake ≥ 1.15was 28 months (95% confidence interval:24-32 months),which was significantly lower than 34 months survival (95% confidence interval:33-35 months) for the patients with RV/LV-FDG < 1.15 (x2 =3.956,P <0.05 ).Conclusions Detection of right ventricle myocardial glucose metabolism level with 18F-FDG SPECT may be a practical method for evaluating haemodynamic change,treatment outcome and prognosis of IPAH.

OBJECTIVE To illuminate the adenoid bacteria distribution in children with adenoid hypertrophy. METHODS PubMed, Embash, Medline, CNKI, VIP Information and Wanfang data were searched for studies on the adenoid bacteria distribution and adenoid hypertrophy. Random effects meta-analysis was used to pool data. RESULTS Nine studies were included in this meta analysis. The pooled detection rates of haemophilus influenza, staphylococcus aureus and streptococcus pneumonia were 0.21 (95%CI, 0.09-0.32), 0.14 (95%CI, 0.09-0.20) and 0.15 (95%CI , 0.08-0.22) respectively. CONCLUSION Haemophilus influenzae, staphylococcus aureus, and streptococcus pneumoniae are three main kinds of pathogenic bacteria of adenoid hypertrophy in children.
