Cisplatin,carpolatin and oxaliplatin are platinum-based drugs that are widely used in cancer chemotherapy. Peripheral neuropathy is major dose-limiting side effect of platinum-based drug. Accordingly, this side effect restrict its clinic application. This review will focus on the research advancement on the mechanism of dorsal root ganglia neurons apoptosis in cellular and molecular biology.

Bilirubin is the final product of aging red blood cells when they were destroyed and degraded. Recent studies have demonstrated that it is a kind of endogenous antioxidant, which plays an important role in anti-atherosclerosis, scavenging free radicals and protecting the tissues and organs from damage. More and more studies have focused on the correlation between bilirubin and ischemic stroke. This article summarized the relationship between the antioxidant system of bilirubin and the occurrence, development and prognosis of atherosclerosis and ischemic stroke.

Objective Severe preeclampsia (sPE), which is usually complicated by small-for-gestational-age (SGA) and immature labor , remains a leading cause of maternal and neonatal mortality and morbidity. This study was to investigate the risk factors of SGA in sPE. Methods We retrospectively analyzed 100 cases of sPE, 35 with SGA (the case group) and the other 65 without it ( the control group ) .We conducted single-factor analysis on the general characteristics and potential impact factors of the patients , i-dentified the independent risk factors of SGA using the un-conditional stepwise logistic model , and assessed the value of umbilical arter-y S/D ratio and proteinuria ration in the diagnosis of sPE with SGA with the ROC curve . Results Compared with the control group , the case group had more cases of early-onset sPE ( P =0.010 ), earlier gestational and delivery weeks (P<0.001), lower neonatal weight at birth ( P<0 .001 ) , higher rate of admission to and longer stay in the neonatal ICU (P<0.001), and higher incidence of neo-natal complications (P<0.05).The case group also showed signifi-cant increases in comparison with the control in the umbilical artery S/D ratio (2.95 ±0.75 vs 2.31 ±0.47, P<0.05), frequency of S/D ratio ≥95th percentile (22.86% vs 6.15%, P<0.01), and rate of proteinuria ≥5 g/24 h (42.86% vs 20.00%, P<0.05).The S/D ratio ≥95th percentile (OR=6.02, 95%CI:2.32-16.78) and proteinuria≥5 g/24 h (OR=1.65, 95%CI:1.56-3.01) were found to be the risk factors of sPE with SGA.The area under the curve was 0.852 for the combination of S/D ra-tio and proteinuria ration in the diagnosis of sPE with SGA (P<0.05). Conclusion Umbilical artery S/D ratio≥95th percentile and proteinuria ≥5 g/24 h contribute to the early prediction, prevention, and prognosis of sPE, and is valuable for the diagnosis of sPE with SGA.

Objective To observe the effects of fenofibrate and pioglitazone on the expressions of PPAR- α, PPAR-γ, and intracellular signaling molecules in pancreatic islets of obese rats induced by high-fat diets. Methods SD obese rat models were established with high-fat diet, and 40 male rats were assigned to 4 groups including high-fat diet (HF group), high-fat diet with fenofibrate (FF group), pioglitazone (FP group) treatment, and control rats with normal diet (NC group). After 8 weeks intervention, immunohistochemistry was performed to evaluate the expressions of various proteins in islets; At the same time, islets mass were scored in tissue slides. Results Islets mass enlarged in HF group. The compositions of islet cells were the same as the control. The expression of insulin was lower in HF group than the control, but after using pioglitazone, less islets mass and more insulin expression were found in FP group. Compared with the control group, expressions of PPAR-α, PPAR-γ protein were reduced in HF group, and the expression of PPAR-α protein increased in FF group, and the expression of PPAR-γ protein was increased in FP group. The levels of NF-кB, p38 mitogen-activated protein kinase (MAPK), ERK1 proteins increased significantly in HF group, the expressions of NF-кB, p38 MAPK decreased in FF and FP groups, and the level of ERK1 decreased only in FP group, the protein level of I-кB showed no difference among control, HF group, and FF groups. Conclusion Fenofibrate and pioglitazone may partially protect islet cells function and improve survival by correcting the disturbance of intracellular signaling molecules.

[Summary] Thoracic paravertebral block ( TPVB) can offer intra-postoperative analgesia for thoracic , cardiac, and breast operations .In recent years , the development of ultrasonic technology provides a platform for real-time and visual never block , which can further improve the success rate and reduce the incidence of complications .In this article, we reviewed the various approaches of ultrasound guidance for thoracic paravertebral blockade , and explored the latest progress of different technologies .

OBJECTIVE:To investigate the concepts and contents of the Chinese precision medicine,and to provide reference for the development of precision medicine in China.METHODS:By evidence-based evaluation method,using jingzhun yixue jingzhun yiliaoprecision medicineas keywords,all literatures were retrieved from CBM,CNKI,Wanfang,VIP,PubMed and Ovid EMBase databases up to Nov.17th,2015.The relevant information were extracted,including researchers (first author or correspondence author's unit belonged to China),domains and concepts.The concepts and contents of the Chinese precision medicine based on China's national condition were summarized and analyzed,and the difference between precision medicine and personalized medicine was compared.RESULTS:54 studies were included,the results indicated most studies (51 literatures) were published in 2015 by hospitals (28 literatures) and high schools (14 literatures);most literatures (23 literatures) presented the concept of precision medicine,followed by disease precision medicine (19 literatures) and relevant technology of precision medicine (7 literatures);a total of 39 literatures presented the specific concept of precision medicine.Besides genetic information involved in American precision medicine,the Chinese one expanded the disease diagnosis and treatment technology,as well as the application.Personalized medicine and precision medicine were in common partially,however,the latter one underlined the disease classification and diagnosis,which was more practicable.CONCLUSIONS:Chinese precision medicine involves disease diagnosis and treatment technology as well as influential factors based on genetic information,and includes disease classification and diagnosis so as to perform personalized precision intervention.The Chinese precision medicine is overall developed and focused.

AIM:To construct the recombinant eukaryotic expression plasmid pEGFP-C1-SR-A I for the high expression in 293T cells in order to identify functions of savenger receptor-A I(SR-A).METHODS:The primer was designed according to MSR1 cDNA and pEGFP-C1-SR-A I was constructed by standard molecular cloning technique and enzyme digestion.After sequencing,the plasmid was transfected into 293T cells by lipidosome method.The expression of scavenger receptor-A I was identified by RT-PCR and Western blotting.The foam cells were evaluated by the formation of lipid granules in the cells with oil red staining.Cell adhesion was analyzed by cell adhesion assay.RESULTS:24 h after transfection,SR-A I mRNA was highly expressed and the high level of the protein was detected.The ratio of foam cell formation was doubled,the efficacy of cell adhesion was enhanced two times compared to the control group and the empty vector group.CONCLUSION:The recombinant eukaryotic expression plasmid has been constructed successfully with enhancing the function of uptake ox-LDL and adhesion in 293T cells by overexpression of SR-A I.
