Objective To investigate the efficacy and toxicity of neoadjuvant regional arterial chemotherapy in the treatment of advanced gastric cancer. Methods The clinical data of 158 patients with advanced gastric cancer and with the same clinical stages who were admitted to Renji Hospital of Shanghai Jiaotong University from February 2002 to May 2005 were retrospectively analysed. Preoperative regional arterial chemotherapy was applied to 76 patients (test group) and the remaining 82 patients only received surgical treatment (control group). The chemotherapy regimen was epirubicin (50 mg/m2) + cisplatin (60 mg/m2) + 5-fluorouracil (1000 mg/m2).This regimen was modified to oxaliplatin (130 mg/m2) + 5-fluorouracil (1000 mg/m2) since 2003, and surgery was performed 6-11 days after the chemotherapy. All patients received postoperative intravenous chemotherapy.The clinical effects, radical resection rate, operative complications and long-term survival of the two treatment methods were evaluated. All data were analysed using the chi-square test and Kaplan-Meier analysis. Results The radical resection rate was significantly higher at 86% (65/76) in the test group compared with 71% (58/82)in the control group ( x2 = 5.01, P ＜ 0. 05 ). The toxicity of the chemotherapy in the test group was mild. The postoperative complication rate was 20% (15/76) in the test group and 16% (13/82) in the control group, with no significant difference between the two groups (x2 = 0.41, P＞0.05). The median survival time was 41 months in the test group and 23 months in the control group. The 5-year overall survival rate was higher in the test group (44.6%) than that in the control group (29.1%) (x2 =3.95, P＜0. 05). Conclusions Neoadjuvant regional arterial chemotherapy is well tolerated by patients with advanced gastric cancer. It is also effective for increasing the radical resection rate and improving the long-term survival.

AlM: To evaluate the effect of rigid gas permeable contact lens ( RGP ) in correcting high myopia and astigmatism.METHODS: Forty-one patients ( 65 eyes ) with myopia (-9. 03 ± 6. 19DS, maximum -23. 00DS) and astigmatism (-1. 41 ± 1. 32DC, maximum -5. 50DC) were fitted with RGP after strict routine ophthalmological examination, objective refraction and subjective refraction. All these patients were followed after 1wk, 1, 3mo and half one year.RESULTS:Sixty-five eyes were fitted with RGP (-9. 92± 5. 96DS). RGP base curve ( BC) was majorly located within the range 7. 20 ~8. 25mm. 46. 2% eyes with RGP achieved 1. 0 ( BCVA ) and 80. 1% achieved above 0. 6 ( BCVA) . However, with spectacles, the percent was 28%(1. 0) and 60% (>0. 6), respectively. BCVA of RGP was 0. 81 ± 0. 22, but BCVA with spectacles was 0. 66 ± 0. 28, there was statistical significance (P<0. 01). There were 40 eyes (62%) fitted with RGP whose vision were enhanced more than 1 line, 24 eyes ( 37%) whose vision were not changed and 1 eye (2%) whose vision were dropped 1 line.CONCLUSlON:RGP effectively improves visual acuity of high myopia and astigmatism compared with spectacles.

AIMTo explore the effect of ligustrazine injection on the expression of heme oxygenase-1 (HO-1) in rabbits with pulmonary ischemia/reperfusion injury after.

METHODSSingle lung ischemia/reperfusion injury animal model was used in vivo. Twenty rabbits were randomly divided into two groups( n = 10, in each), pulmonary ischemia/reperfusion injury (I/R) group and I/R + ligustrazine injection (LGT) group. The tissue slides were stained by immunohistochemistry (IHC) and in situ hybridization (ISH) for HO-1 to detect the expression of HO-1 in lung and to analyze the absorbance, wet to dry ratio of lung tissue weight (W/D) and the injured alveoli rate (IAR) were measured at 180 minutes after lung reperfusion. Meanwhile the lung tissue slide was prepared for electron microscopic observation at 180 minutes after reperfusion.

RESULTSHO-1 expression was upregulated in two groups in the pulmonary endothelial cells, part of pulmonary vascular smooth muscle cells, extima of vessels and epithelial cells of airway, the absorbance was 0.168 +/- 0.016 (0.148 +/- 0.013), 0.186 +/- 0.014 (0.158 +/- 0.012) respectively.The LGTI group showed higher absorbance than those of the I/R group (P < 0.01), lower W/D and IAR values than those of the I/R group (P < 0.01) significantly and lighter abnormal changes of the lung tissue in morphology than those of the I/R group.

CONCLUSIONLigustrazine injection possesses notable protective effects on I/R in rabbits by increasing the expression of HO-1 in lung.

OBJECTIVETo study the relationship between fetomaternal cellular traffic and hepatitis B virus (HBV) intrauterine infection.

METHODSMaternal DNA and fetal DNA were amplified by short tandem repeat (STR)-polymerase chain reaction (PCR), allele-specific PCR (As-PCR) and heminested PCR (hemi-nPCR). Cell transfer from mother-to-fetus or fetus-to-mother was determined by detecting the existence of TH01, GSTM1 and ACE. The relationship between cell transfer from mother-to-fetus and HBV intrauterine infection was analyzed by nested case-control study.

RESULTS26 of the 42 informative mother-baby pairs indicated mother-to-fetus cell traffic, 32 of the 40 informative mother-baby pairs indicated fetus-to-mother cell traffic and two-way cell traffic occurred in 10 mother-baby pairs. Statistical analysis demonstrated that the mother-to-fetus instead of fetus-to-mother cell traffic presented the association with HBV intrauterine infection. There was no significant correlation between mother-to-fetus cell traffic or the fetus-to-mother cell traffic. Both mother-to-fetus cell traffic and PBMC HBV DNA positivity appeared in pregnant women were risk factors of HBV intrauterine infection but the two did not manifest the interaction. The positive risk factors of positivity PBMC HBV DNA in newborns would included mother-to-fetus cell traffic and PBMC HBV DNA in pregnant women, also did not display the interaction.

CONCLUSIONThe cell traffic from HBsAg positive mother to fetus had more contribution to HBV intrauterine infection, which was possibly one of the HBV routes of intrauterine infecting.

Abstract: The demand for reliable toxicological data of chemicals runs through every link of occupational health work. The prevention of occupational diseases involves high requirements for the standardization of chemical toxicity assessment in occupational health institutions. Good laboratory practice (GLP) emphasizes the integrity of the test process to trace and supervise the whole process of the test, which is conducive to the standardization of chemical toxicity identification. Therefore, the standardized construction of GLP laboratories is an important starting point for occupational health institutions to carry out chemical toxicity identification. In the construction and management process of GLP laboratories for chemical toxicity identification, occupational health institutions need to build a sound organization and operation system, carry out systematic training and assessment of personnel, establish standard operating norms and emphasize their importance, strengthen the management of facility environment and laboratory, pay attention to quality control and process supervision, and constantly improve their own ability level. To actively adapt to social development and market demand, to provide strong support for occupational health work.

OBJECTIVETo investigate the HCV genotypes distribution in northern and southern cities in China and the difference between patients infected with HCV by transfusion and non-transfusion routes.

METHODSThe HCV genotypes of the patients with chronic hepatitis C from 9 cities belonging to different regions were genotyped by the PCR products of 5 prime untranslated region NTR digested with restriction endonucleases, and the HCV genotypes distribution among different cities or between the patients infected with HCV through transfusion and other routes was analyzed.

RESULTSThe HCV genotypes of 214 in 219 cases were determined; 197 patients were infected with monogenotype HCV. The major epidemic genotypes of HCV isolates in China were 1b (76.64%) and 2a (18.22%), but 5.14% of patients were infected with HCV belonging to genotype 3b and this was the first report that there is genotype 4a in China. The HCV genotype distribution was not different in northern and southern areas, but was significantly different between patients infected with HCV through transfusion and non-transfusion routes (P=0.036). In patients infected trough transfusion, the rates of monogenotype HCV infection and genotype 1b were 93.88% and 76.87%, respectively, which were higher than those (86.57% and 58.21%) in the patients infected with HCV through non-transfusion routes. The rate of patient infected with mixed genotype HCV strains in non-transfusion group was 13.43%, which was higher than that (6.12%) of patients in transfusion group.

CONCLUSIONThe HCV genotype distribution in northern and southern regions were similar, but was significantly different between the patients infected through transfusion and other routes.
