ObjectiveTo establish the human periodontal ligament fibroblasts(HPDLFs)that express BMP2 and observe their biologicl characterization. MethodsA phagemid expression vector for BMP2 (pBK-B2) was transfected into HPDLFs by using LipofectAMINE. The BMP2 expression was determined by the immunohistochemical ABC method. The alkaline phosphatase (ALP) activity, osteocalcin (OC) production and capacity of mineralization were measured in the transfected cells. ResultsBMP2 protein was expressed in HPDLFs after gene transfection. The BMP2 gene transfected cells showed prominently elevated ALP activity, OC production and increase in mineralized nodules. ConclusionThe results indicate that BMP2 is expressed in HPDLFs and is involved in inducing differ- entiation of HPDLFs into osteoblast-like cells.

Gray relational analysis is employed to analyze the effects of nano-drug features on phagocytosis of macrophages, including zeta potential, shape factor and scale size of drug particle, the correlation among such factors and macrophage cell is calculated. The results showed that the internalization processe is affected significantly by the zeta potential of the drug in the process of phagocytosis of macrophages, followed by the impact particle shape, and the effect of particle scale behaves relatively small.

A new risk analysis method based upon reliability theory was introduced in this paper for the quality risk management of Chinese medicine injection manufacturing plants. The risk events including both cause and effect ones were derived in the framework as nodes with a Bayesian network analysis approach. It thus transforms the risk analysis results from failure mode and effect analysis (FMEA) into a Bayesian network platform. With its structure and parameters determined, the network can be used to evaluate the system reliability quantitatively with probabilistic analytical appraoches. Using network analysis tools such as GeNie and AgenaRisk, we are able to find the nodes that are most critical to influence the system reliability. The importance of each node to the system can be quantitatively evaluated by calculating the effect of the node on the overall risk, and minimization plan can be determined accordingly to reduce their influences and improve the system reliability. Using the Shengmai injection manufacturing plant of SZYY Ltd as a user case, we analyzed the quality risk with both static FMEA analysis and dynamic Bayesian Network analysis. The potential risk factors for the quality of Shengmai injection manufacturing were identified with the network analysis platform. Quality assurance actions were further defined to reduce the risk and improve the product quality.

Huge amount of data becomes available from the pharmaceutical manufacturing process with wide application of in- dustrial automatic control technology in traditional Chinese medicine (TCM) industry. The industrial big data thus provides golden op- portunities to better understand the manufacturing process and improve the process performance. Therefore it is important to implement data integration and management systems in TCM plants to easily collect, integrate, store, analyze, communicate and visulize the data with high efficiency. It could break the data island and discover useful information and knowledge to improve the manufacturing process performance. The key supporting technologies for TCM manufacturing and industrial big data management were introduced in this paper, with a specific focus on data mining and visualization technologies. Using historic data collected from a manufacturing plant of Shengmai injection of SZYY group, we illustrated the usefulness and discussed future prospects of data mining and visualization technologies.

0.05).Conclusions Neither the new nor old SIRS diagnostic criteria had a high conforning rate with neonatal critical illnesses;There was no significant difference between them in each clinical item.It shows that the new SIRS diagnostic criteria is not superior to the old one,therefore we should improve the neonatal SIRS diagnostic criteria in the future.

This article explored professor Wang Qingqi's clinical experiences in treating gastroesophageal reflux disease(GERD) with traditional Chinese medicine(TCM).According to clinical observation,the key pathogenesis of GERD is abnormal rising and falling of vital energy,presenting in the five aspects of incoordination between the gallbladder and stomach,incoordination between the liver and stomach,stagnation of liver-qi with deficiency of the spleen,weakness of the spleen and stomach and qi-stagnancy and blood stasis.It will get a good curative effect when adopting the TCM methods of acrid-release and bitter-downbearing therapy,worm-like paired Chinese material medica and the opposite complementary relationship therapy.

ObjectiveTo analyze the complications of cerebral palsy (CP) children.Methods195 CP children (113 boys and 82 girls, 7 months to 11 years old) were examined by electroencephalogram, eye consultation, auditory brainstem response and Gesell developmental schedule except routine examinations to detect the complications.Results27(13.8%) CP children had motor delay as the only sign. 168 CP children had one or more complications, 168(86.2%) cases with mental retardation, 92(47.2%) cases with visual disability, 40(20.5%) cases with growth delay, 25( 12.8 %) cases with epilepsy, 12(6.2%) cases with hearing disability, 11(5.6%) cases with microcephaly, 3(1.5%) cases with abnormal behavior. 15(7.7%) cases of CP children had at least two kinds of complications, 123(63.1%) cases had three kinds of complications, 30(15.4%) cases had four kinds of complications.ConclusionMost of the CP children have one or more complications.

Abstract?AIM:To evaluate the efficacy of photocoagulation alone or combined with intravitreal Bevacizumab for radiation retinopathy ( RR) .?METHODS: There were 43 patients ( 43 eyes ) with RR were collected at the Fifth Affiliated Hospital Sun Yet-Sen University between Jan.2009 and Jan.2014.Twenty-one patients received the photocoagulation treatment combined with intravitreal bevacizumab and 22 patients received the treatment of photocoagulation alone.All the patients would complete ophthalmologic examinations, including best -corrected visual acuity ( BCVA ) , intraocular pressure, optical coherence tomography, fundus fluorescein angiography before and after the treatment.?RESULTS:BCVA:In monotherapy group, there were no statistically difference about BCVA before and after treatment ( P>0.05).In combined therapy group, the BCVA had been increasing gradually in 2wk, 1, 3, 6mo after treatment ( P <0.05 ). There was no significant difference about BCVA before and 1a after treatment ( P>0.05).In the comparison of BCVA in these two groups in 2wk, 1, 3, 6mo after treatment, the combined therapy group were better than monotherapy group in each time point (P<0.05), but no statistically significant difference was observed in these two groups at 1a after treatment (P>0.05).Central macular thickness (CMT):in monotherapy group, the CMT had been decreasing gradually in 2wk, 1, 3, 6mo after treatment ( P <0.05 ). There was no significant difference about CMT before and after 1a treatment ( P>0.05).In combined therapy group, the CMT had been decreasing gradually in 2wk, 1, 3, 6mo after treatment ( P<0.05 ). There was no significant difference about CMT before and 1a after treatment ( P>0.05).In the comparison of CMT between these two groups in the 2wk, 1, 3, 6mo after treatment, those of combined therapy group were thinner and difference were statistically significant ( P <0.05 ), but no statistically significant difference was observed in two groups at 1a after treatment (P>0.05).? CONCLUSION: Photocoagulation combined with intravitreal bevacizumab for the treatment of radiation retinopathy both have an effect on reducing the macular edema in a short time (6mo).But the long-term efficacy is poor.

Objective To investigate the accuracy for absolute quantification of brain creatine (Cr) concentration using long time echo (TE) point resolved spectroscopy (PRESS) sequence performed with an external standard and postprocessed with the linear combination of model spectra (LCModel).Methods Ten swine (3.1±0.6 kg) and an external standard phantom containing detectable compounds of known concentration were investigated in this study by using 1.5 T GE Signa scanner and a standard head coil. The single-voxel proton magnetic resonance spectroscopy (1H-MRS) data were acquired from the two ROIs (2 cm×2 cm×2 cm) placed in swine brain and external standard solution using PRESS sequence with TE 135 ms,TR 1500 ms,and 128 scan averages.The in vivo quantification of Cr was accomplished by LCModel.After 1H-MRS examination,each animal was sacrificed immediately.In vitro Cr concentration was analyzed by high performance liquid chromatography (HPLC).Results In the 1H-MRS group,the Cr concentration was (9.37±0.14)mmol/kg.In the HPLC group,the Cr concentration was (8.91±0.13)mmol/kg.Good agreement was obtained between these two methods (t=9.038,P=0.491).Conclusion The long echo time PRESS sequence performed with an external standard and processed with LCModel iS proven to be an accurate technique to detect the in vivo brain Cr concentration.

Retinal vein occlusion (RVO) is a common clinical disease causing vision loss. Risk factors such as diabetes, atherosclerosis are closely associated with RVO. Xuesaitong injection is used extensively in clinical treatment of RVO, however the mechanism is still unclear. In this study, we investigated the protective effect of Xuesaitong injection on RVO rat model. Using a compound-target network of Xuesaitong on anti-RVO constructed by literature mining, we aim to elucidate the multi-compound, multi-target effect of Xuesaitong injection. Fifteen potential targets of Xuesaitong injection associated with inflammation, angiogenesis, apoptosis, and coagulation were identified in this study. VEGF, IL-1beta and IL-6, three important targets in the compound-target network were further experimentally validated. This study provided experimental evidence for Xuesaitong injection being effective in treating RVO and a network view on its anti-RVO mode of action through a multi-compound and multiple-target mechanism.
