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.

[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 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.

Objective To compare the characteristics of intrahepatic cholangiocarcinoma (ICC) and different differentiated hepatocellular carcinoma (HCC) by CEUS and evaluate the diagnostic value of CEUS.Methods The cases who underwent CEUS and were pathologically demonstrated as ICC (n=34) and HCC (n=136) were observed.The characteristics of ICC and different differentiated HCC in conventional ultrasound and CEUS were analyzed,and the diagnostic efficiency of wash out time were calculated.Results ICC had higher percentage (24/34,70.59％) of washout emerging in early portal phase than those of HCC.And ICC had lower percentage (0;4/34,11.76％) of washout emerging in middle and late portal phase than poorly and moderate differentiated HCC.Poorly differentiated HCCs had higher percentage (16/41,39.02％) of washout emerging in middle portal phase than well differentiated HCC.The sensitivity,specificity,positive predictive value,negative predictive value,accuracy,positive likelihood ratio and negative likelihood ratio of washout time in diagnosis of ICC were 82.35 ％ (28/34),91.18％ (124/136),70.00％ (28/40),95.38％ (124/130),89.41％ (152/170),9.4,0.2,respectively.The rise time of ICC and well,moderate and poorly differentiated HCC were (13.03 ± 3.49) s,(13.80 ± 3.04)s,(14.89±4.12)s,(16.00±3.38)s,respectively,and the difference was significant (F=4.369,P＜0.05).The rise time of ICC was significantly higher than that of well differentiated HCC (P＜0.05).Conclusion The CEUS performances are different significantly among ICCs and different differentiated HCCs,which has value for the differential diagnosis.

Objective To provide evidence for diagnosis and treatment by investigating the pathogens and drug resistance of immunocompromised host (ICH)pneumonias.Methods Statistical method was used to analyze retrospectively the data of pathogens and drug resistance of ICH pneumonia treated in our hospital in 2014. Results We confirmed 187 cases of ICH pneumonia by pathogen study of 324 patients.Gram-negative bacillus (68.42%)was the main pathogen of ICH pneumonia.Acinetobacter baumanii (AB)accounted for the first place. Staphylococcus aureus infection was still the first of Gram-positive coccus.Conclusion Gram-negative bacillus was the main pathogen of ICH pneumonia in our hospital and the isolated bacteria show strong antibiotic resistance. Therefore,it is necessary to strengthen dynamic monitoring of pathogens in the secretions from ICH pneumonia patients’ lower respiratory tract and drug resistance.It is suggested that clinicians make anti-infection treatment cover drug-resistant bacteria.
