The specific fragment of Pneumococcal surface protein A(PspA)and Pneumococcal Surface Adhesin A(PsaA)gene was amplified by PCR from Streptococcus pneumonia 5 and Streptococcus pneumonia 19.The amplified fragnent of PspA and PsaA gene was ligated into pET-27b(+)vector and transformed into BL 21 E.coli for expression and obtain the expressive production of PspA and PsaA.Induced by IPTG,the expression level was as high as 75 % of the total disolube protein.The result showed that the recombinant plasmid could express a specific 75 kDa and 37 kDa fusion protein in E.coli BL 21,which showed the good immunogenicity and a broadly cross reactivity with the other serotypes.

OBJECTIVETo study the autophagy activity between rat bone marrow stem cells (BMSCs) neural differentiation in order to explore the mechanism involve in this process.

METHODSBMSCs were passed by 3 generation, then was induced with the revulsant 2% (DMSO) + 200 µmol/L (BHA), NSE expression was detected by immunocytochemical stain, the mRNA expression of autophagy associated genes L3B, Beclinl, Atg5, Atg7, Atg10 were detected by RT-PCR, the autophagy protein LC3B was examined by Western blot and flow cytometry analysis.

RESULTSBMSCs were passed by 3 generation, the purity of BMSCs could reach more than 90%, the morphology of cells were like fibroblasts, after the revulsant 2% DMSO + 200 µmol/L BRA induced, cells were extended long neurites, like nerve cells, positive rate of NSE staining was (83±5) %, RT-PCR results showed that the expression of autophagy associated genes LC3B, Beclinl, Atg5, Atg7 Atg0 were rised after BMSCs neural differentiation, Western blot analysis showed that the LC3B-II protein expression was increased after neural differentiation and the MFI of L3B was highten by flow cytometry.

CONCLUSIONAutophagy is increased after rat BMSC neural differentiation.

BackgroundIt is important to measure the corneal curvature, anterior chamber depth (ACD) and axial length accurately for calculating IOL power. The interchange outcomes from different measuring methods and apparatus will cause unreliable IOL power. ObjectiveThe present study was to compare the differences of corneal curvature, anterior chamber depth (ACD) measured by IOLMaster and Orbscan Ⅱbefore and after laser in situ keratomileusis(LASIK) and further compare the axial length measured by IOLMaster and A-ultrasound. Methods One hundred and thirty eyes from 65 consecutive myopic patients before LASIK and 56 eyes of 28 cases with 1-month follow-up duration after LASIK in Henan Eye Institute were enrolled in this study. The K value, ACD between IOLMaster and Orbscan Ⅱ as well as results of axial length between IOLMaster and A-ultrasound were compared by using paired t test. The agreements of the measured values among IOLMaster, Orbscan Ⅱ and A-ultrasound were evaluated using Bland-Altman plot. ResultsBefore LASIK,the K value measured by IOLMaster,Orbscan Ⅱ were ( 43.32 ± 1.52 ) D and ( 42.99 ± 1.45 ) D respectively with the difference value of( 0. 33 ±0. 03 ) D, showing a significant difference(t=10. 380,P=0.000) and a positive relation between them(r=0.971,P=0.000). After LASIK,the K value measured by IOLMaster, Orbscan Ⅱwere(39. 02±2. 14) D and ( 38.91 ±2. 04) D with the difference value (0. 12±0. 33 ) D, presenting a significant differences between them (t =2.715, P =0.009). Bland-Altman plots indicated the disagreement in K value and uninterchangeable. Before LASIK, the ACD measured by IOLMaster,Orbscan Ⅱ and A-ultrasound were ( 3.72 ± 0. 22 ) mm, ( 3.69 ±0. 22 ) mm and ( 3.75± 0.27 )mm respectively and no significant differences were found between them (P ＞ 0. 05 ). Axial length measured by IOLMaster significantly prolonged in comparison with A-ultrasound(25.59± 1. 01 mm vs 25.22±0.99 mm ) , and the difference was( -0. 37 ±0. 30 ) mm, showing significant difference ( t =- 14. 098, P =0. 000 ) and positive correlation ( r =0. 954, P =0. 000 ). Axial length values measured by IOLMaster were ( 25.54 ± 1.05 ) mm in preoperation and ( 25.48 ± 1.01 ) mm in postoperation with the difference (0.052±0. 412)mm, showing statistically insignificant difference between them (t=0. 946,P=0. 348). ConclusionsKeratometries measured by IOLMaster,Orbscan Ⅱ are much more different. Therefore,these two methods are not recommended to use interchangely. ACD measured by IOLMaster,Orbscan Ⅱ and A ultrasound are proved to obtain the similar results and is clinically interchange. Axial length measured by IOLMaster is longer than that measured by A-ultrasound.

The development of acupuncture-moxibustion and Tuina in Namibia was introduced in the article. The history of acupuncture in Namibia is only 15 years, and there are 3 acupuncturists and Tuina practitioners with permanent resident permit in Namibia. The University of Namibia has already established a medical college, which is now cooperating with the concerning Chinese medical university of China and carrying out education for the undergraduate students. The development of acupuncture-moxibustion and Tuina has a great potential in Namibia with an extensive indication involving diseases of internal medicine, surgery, gynecology, pediatrics, orthopedics, and neurology.

OBJECTIVETo preliminary study the long term therapeutic effects of repeat the whole lung lavage (RWLL) in the treatment of silicosis.

METHODSA total of 60 patients with silicosis in the same stone mine were randomly and equally divided into repeat the whole lung Lavage (RWLL) group and whole lung Lavage (WLL) group based on silicosis staging, age and working age of dust exposure. Comparative analysis was performed to evaluate the long-term therapeutic efficacy and safety of RWLL. The cell count and SiO2 content were measured in twice right lung bronchoalveolar lavage fluid(BALF) of the RWLL group.

RESULTSFour years after treatment, the cough and asthma improvement rates of the RWLL group were 68.4% and 75.0% higher than those (52.4%and 57.9%) of the WLL group (P > 0.05). Six years after treatment, the asthma improvement rate (70.0%) of the RWLL group was significantly higher than that (36.8%) of the WLL group (P < 0.05). The RWLL group showed slight decrease in forced vital capacity (FVC) and forced expiratory volume in one second (FEV1.0) after treatment (P > 0.05), while the WLL group showed significant decrease in FVC and FEV1.0 in the six years after treatment (P<0.05). Four and Six years after treatment, the RWLL group had higher no change rate and lower progression rate and significant progression rate than the WLL group in terms of chest X-ray (P>0.05). In the RWLL group,the first time the right lung BALF test showed a number of cells 6.71×10(7)∼2.14×10(9)/L, average 4.50×10(8)/L, pulmonary alveoli macrophages (PAM) ratio of 0.873∼0.980, average 0.954 and SiO2 content of 18∼104.7 mg, average 93.7 mg; the second test showed a number of cells 5.71×10(6)∼1.30×10(9)/L, average 9.12×10(7)/L; PAM ratio 0.710∼0.926, average 0.870 and SiO2 content of 6∼90.2 mg, average 46.2 mg. The RWLL group happened hemoptysis, chest pain one case in perioperative period, the incidence of 6.7%. The RWLL group complicated by left pneumothorax, pulmonary infection one case and the WLL group complicated by one case of lung cancer in a year of follow-up.

CONCLUSIONRWLL is reasonable and safe treatment which could help to further improve the long-term effects of WLL for silicosis.

To observe the effects of phenylallyl compounds on prostaglandin E2 (PGE2) release in mouse cerebral microvascular endothelial cells (bEnd. 3) stimulated by IL-1beta, and to analyze their structure-activity relationship. Different concentrations of phenylallyl compounds were added separately, and the content of PGE2 induced by IL-1beta in the culture media was measured by ELISA assay. The 50% inhibitory concentration (IC50) of PGE2 was calculated. Studies showed that phenylallyl compounds could affect the PGE2 release differently in bEnd. 3 cells induced by IL-1beta. Close relationships were shown between the inhibitory activities and the location and number of the substituent groups. In conclusion, phenylallyl compounds exhibited inhibitory activities at different extent on PGE2 release in bEnd. 3 cells stimulated by IL-1beta and presented certain structure-activity relationship.
