Oxaliplatin, the third generation of the platinum based chemotherapy agent, is effective in the treatment of multiple solid tumors and is also quite safe. However, there is a high incidence of peripheral neurotoxiciy, which is dose-limiting. Oxaliplatin induces two distinct forms of neurotoxicity: an acute syndrome that is triggered or aggravated by exposure to cold, and chronic cumulative sensory neurotoxicity which in nature resembles characteristics of cisplatin associated neurotoxicity. In this article, the clinical manifestations, electrophysiologic abnormalities, mechanism of neurotoxicity and therapy are reviewed.

BACKGROUND: Animal experiments showed that recruitment maneuver (RM) and protective ventilation strategy of the lung could improve oxygenation and reduce extravascular lung water. This study was to investigate the effects of RM on respiratory mechanics and extravascular lung water index ( EVLWI) in patients with acute respiratory distress syndrome (ARDS). METHODS: Thirty patients with ARDS were randomized into a RM group and a non-RM group. In the RM group, after basic mechanical ventilation stabilized for 30 minutes, RM was performed and repeated once every 12 hours for 3 days. In the non-RM group, lung protective strategy was conducted without RM. Oxygenation index (PaO2/FiO2), peak inspiratory pressure (PIP), Plateau pressure (Pplat), static pulmonary compliance (Cst) and EVLWI of patients before treatment and at 12, 24, 48, 72 hours after the treatment were measured and compared between the groups. Hemodynamic changes were observed before and after RM. One-way ANOVA, Student's t test and Fisher's exact test were used to process the data. RESULTS: The levels of PaO2/FiO2 and Cst increased after treatment in the two groups, but they were higher in the RM group than in the non-RM group (P<0.05). The PIP and Pplat decreased after treatment in the two groups, but they were lower in the RM group than in the non-RM group (P<0.05). The EVLWI in the two groups showed downward trend after treatment (P<0.05), and the differences were signifcant at all time points (P<0.01); the EVLWI in the RM group was lower than that in the non-RM group at 12, 24, 48 and 72 hours (P<0.05 or P<0.01). Compared with pre-RM, hemodynamics changes during RM were significantly different (P<0.01); compared with pre-RM, the changes were not significantly different at 120 seconds after the end of RM (P>0.05). CONCLUSIONS: RM could reduce EVLWI, increase oxygenation and lung compliance. The effect of RM on hemodynamics was transient.

Objective To investigate the feasibility and preventive effect of benign esophageal restenosis by binding 125I seeds to upper esophageal stent through animal experiments.Methods Eight 125I seeds were evenly bound to upper normal esophageal stents for the animal experiments.A total of 32 beagle dogs were randomly assigned to 2 groups:experimental group,implanted with esophageal stents with eight 125I seeds (33.3 MBq),and the control (stents without 125I seeds).Four dogs of each group were killed at the 1 st,2nd,4th,and 8th week after imaging studies.The tissue of 2 cm upper stent underwent pathology analysis.Results All the novel stents were successfully implanted.No radioactive leak was detected by ECT.The lumen diameter of the top stent showed the tract gradually narrowed and at the 4th and 8th weeks,the experiment group narrowed more seriously compared with the control group and the difference was statistically significant (P ＜ 0.05).PCNA,ot-SMA mean optical density were significantly different in the 4th week.Both hydroxyproline and total amino acid increased progressively,with significant difference at the 4th and 8th weeks.The macroscopic and optical findings of the trachea and major vessels were basically the same in both groups.Conclusion The novel stent is feasible and safe for preventing benign esophageal restenosis and preventing benign esophageal stent restenosis.

Objective To investigate the influence factors of non-responsiveness and lowresponsiveness to hepatitis B vaccine of infants born to hepatitis 1 surface antigen (HBsAg) positive mothers.Methods A total of 219 HBsAg positive mothers and their full-term neonates were selected from July 2011 to December 2012 in the Third People's Hospital of Taiyuan.Serologic hepatitis B virus (HBV) markers and HBV DNA load of mothers and their neonates were determined.Neonates were followed up for 12 months to observe the effect of HBV intrauterine infection,hepatitis B e antigen (HBeAg) status,sex,delivery mode,feeding option and suffering from infectious disease during followup period on the immune response to hepatitis B vaccine.Chi-square test was used in univariate analyses and unconditional Logistical regression was used in multivariate analyses.Results There were 16 cases of non-responsiveness and 33 cases of low-responsiveness in all 219 neonates.The rate of non-responsiveness and low-responsiveness was 22.37 ％.In univariate analyses,neonatal HBeAg positivity (x2 =4.895,P=0.027),natural birth (x2 =5.210,P=0.022),suffering from infectious diseases during follow-up period (x2 =4.329,P=0.037) were significantly associated with non-responsiveness and low-responsiveness.There was no relationship between mother HBeAg positivity and the level of response to hepatitis B vaccine.In multivariate analyses,natural birth (OR=2.022,95 ％CI:1.045-3.914) and suffering from infectious diseases (OR=2.324,95 ％ CI:1.058-5.103) were associated with non-responsiveness and low-responsiveness.Conclusion Infants born to HBsAg positive mothers with natural birth or suffering from infectious diseases during follow-up period are more likely to be non-responsiveness and lowresponsiveness to hepatitis B vaccine.

Objective To investigate the influence factors of quantitative changes of dendritic cells (DC) in neonate born to HBsAg positive mother.Methods Sixty HBsAg positive mothers and their newborns were enrolled from the Third People's Hospital of Taiyuan from July 2011 to March 2012.The serum hepatitis B virus (HBV) markers and HBV DNA in mothers and newborns before vaccination were determined by chemiluminescence immunoassay (CLIA) and fluorescence quantitative polymerase chain reaction (PCR).The circulating frequencies of DC subsets were determined in the newborns by flow cytometry (FCM).The comparison of data was done by Mann-Whitney test and t test.The correlation analysis was done by Spearman rank correlation analysis and chi square test.Results Among 60 newborns,5 were HBsAg positive and HBV DNA negative.Among 60 HBsAg positive mothers,21 were HBeAg positive and 29 were HBV DNA positive.There was no significant quantitative difference of neonatal myeloid dendritic cells (mDC) and plasmacytoid dendritic cells (pDC) between intrauterine infection group and intrauterine non-infection group (Z=-0.535,P=0.59 and Z=-0.027,P=0.98,respectively).However,mother's HBeAg positive status was closely related with neonatal HBeAg positive status (Pearson contingency coefficient was 0.928,P＜0.01).The frequencies of mDC in newborns born to HBeAg positive mothers were significantly lower than those born to HBeAg negative mothers (0.60±0.57 vs 0.87±0.58; Z=-2.085,P＜0.05).However,there was no significant quantitative differences of mDC and pDC between newborns born to HBV DNA positive mothers and born to negative mothers (Z=-1.272,P=0.20 and Z=-0.806,P=0.42,respectively).The frequencies of pDC were significantly lower in newborns born to mothers with HBV DNA＞ 1 × 107 copy/mL compared to newborns born to HBV DNA negative mothers (0.30±0.18 vs 0.64±0.55; t=-2.996,P=0.005).Conclusions HBeAg positive status of mothers may reduce neonatal frequencies of mDC.Neonatal frequencies of pDC may be reduced when the mothers' HBV DNA loads are more than 1 × 107 copy/mL.

OBJECTIVETo study the clinical and radiographic results of tatal hip arthroplasty (THA) with an uncemented femoral component after 6 to 10 years follow-up, and to investigate factors effecting their efficacy.

METHODSFrom January 2000 to December 2003, 58 patients were treated with primary total hip arthroplasty. Among the patients, 27 patients were male and 31 patients were female, ranging in age from 25 to 73 years, with an average of 56 years. The 58 patients were clinically and radiographically followed up including before operation, postoperative 1.5, 3, 6 and 12 months, and then once a year. Therapeutic evaluation was measured by using Harris scoring system. The incidence of osteolysis around the components in different Gruen zones was radiologically determined. The data were analyzed by SPSS 16.0 software.

RESULTSAll the patients were followed up, and the duration ranged from 6 to 10 years, with a mean of 8.2 years. The Harris hip score of the patients improved from preoperative mean of (54.0 +/- 7.8) to (88.3 +/- 6.1) at the latest follow-up. There were 32 patients with an excellent result, 22 good, 3 fair and 1 poor. Radiological analysis showed that 48 patients had stable bone in growth, 10 patients got stable fibrous in growth and nobody showed unstable fixation with aseptic loosening. Subsidence (1 to 3 mm) was observed in 4 patients. Osteolysis of the femoral cortex was seen in 4 patients without progressive development, and the latest follow-up radiographs showed a significantly greater incidence of osteolysis in Gruen zone I, VI, VII compared with others (P = 0.031). All the patients with low Harris score had received prostheses which were undersized in the intramedullary canal, and these differences were statistically significant.

CONCLUSIONThe uncemented femoral component has good medium-term clinical follow-up results because of high stability and no aseptic loosening.

OBJECTIVETo observe the protective effect of Panax Ginseng (PG), Aconitum Carmichaeli (AC), and their combination (PG-AC) on myocardial ischemia/reperfusion injury in rats.

METHODSRat's ischemia reperfusion injury model was established by ligating left anterior descending coronary artery for 60 min followed by reperfusion for 240 min. Forty male rats were randomly divided into five groups, the sham operation group, the model group, the three treated groups. The three treated groups were treated with PG, AC and PG-AC respectively by given the drugs 10 min before ischemia reperfusion, and to the sham operation group and the model group, saline was given instead. The infarction area, pathologic changes of myocardial tissue (under light and electron microscopy), activity of creatine phosphokinase (CK) and lactate dehydrogenase (LDH) in serum, content of malondialdehyde (MDA) and superoxide dismutase (SOD) in myocardial tissue were observed to evaluate the protective effect of treatment.

RESULTSThe area of acute myocardial infarction was lesser, activity of LDH and CK were lower in the three treated groups than those in the model group. Content of SOD was significantly higher and that of MDA was markedly lower in the former three than those in the model group. Light and electron microscopic examination showed that the necrotic degeneration and pathologic changes of myocardiocytes in the treated groups were significantly milder than that of the model group. As comparing the effect between the three treated groups, PG-AC showed the best, and insignificant difference was shown between PG and AC.

CONCLUSIONBoth PG and AC, and their combination have obviously protective effects on myocardium against ischemia reperfusion injury, which of PG-AC is superior to that of PG or AC used singly.
