Peripheral blood mononuclear cells from 32 cases of osteosarcoma and 20 normal controls were separated and induced by lipopolysaccharide, followed by 48 hour incubation in vitro, then the supernatant were collected. The levels of IL-6 were measured by enzyme linked immunosorbent assays, the concentrations of NO were measured by Griess methods. The results were as follows: The concentrations of IL-6 and NO were significantly higher than those in normal contrls (P<0.01). There were positive correlation between the levels of IL-6 and NO in patients with osteosarcoma (r=0.652, P<0.01). The results suggest that the immune function of peripheral mononuclear cell in patients with osteosarcoma was disordered. It may activate peripheral mononuclear cells to produce high levels of IL-6 and NO, which may take part in the pathogenesis of osteosarcoma.

Objective To investigate the efficacy and side effects of new combination of high-dose methotrexate (MTX),cisplatin (DDP),pirarubicin (THP),and ifosfamide (IFO) in the treatment of extremity osteosarcoma patients.Methods A retrospective analysis was conducted for 125 osteosarcoma patients treated with the optimized neo-adjuvant chemotherapy combined with the four drugs mentioned above (MTX 200 mg/kg iv 6 h d1,CF 9 mg at one time,12 times; DDP 100 mg/m2,THP 30 mg iv,d8-10;IFO 3.0 g/m2 iv d16-18,mesna after IFO for 0,3,6,9 h).The efficacy and side effects of the therapeutic scheme were evaluated.Results The effective salvage rates of Ⅱ a and Ⅱb schemes were 36.4％ (8/22) and 79.6％ (82/103) with a statistical significance (P ＜ 0.05).The 2-year survival rate of schemes was 62.4％,and the survival time was(17.7 ± 8.3)months.The main side effects were myelo-suppression,nausea,and vomiting,etc.The incidence rate of myelo-suppression,nausea,and vomiting with grade Ⅲ-Ⅳ accounted for 71.2％,37.6％,and 13.6％,respectively.Conclusions The optimized neo-adjuvant therapy strategy based on high-dose MTX,DDP,THP,and IFO is effective in the treatment of osteosarcoma.

Objective To explore the value of Toll-like receptor 2(TLR2) on the diagnosis of neonatal septicemia especially for the early diagnosis.Methods Twenty-two newborns with septicemia were divided into 2 groups according to the time of onset:early-onset group(n=12) and late-onset group(n=10).Another 14 non-infectious newborns were collected as control group.The TLR2 mRNA in peripheral blood was detected by real-time polymerase chain reaction,and mononuclear cells were isolated by the density gradient centrifuga-tion;the C reaction protein(CRP) was detected,and the co-relationship of the indexes was analyzed by Pearson correlation analysis.Results 1.The level of CRP in early-onset group were(157.89?32.96) ng?L-1,and(89.78?16.24) ng?L-1 in late-onset group,and there was significant difference between both groups(P=0.001);(6.91?1.20) ng?L-1 in control group,which was significantly lower than that in early-onset group and late-onset group(P=0.000,0.001).2.The expression of TLR2 mRNA in early-onset group and late-onset group was(57.38?10.72)?1012 copies?L-1and(32.74?4.65) ?1012 copies?L-1,which was significantly higher than that in control group[(4.12?0.68) ?1012 copies?L-1].3.CRP is positively correlated with TLR2 mRNA(C=0.972,P=0.000).Conclusions TLR2 expression is proven to be related to both the level of CRP and the stage of onset and may play a key role in the pathogenesis of neonatal septicemia.Detection for TLR2 may assist the earlier diagnose of atypical neonatal septicemia.

Background Aspheric intraocular lens (IOL) is designed to reduce the spherical aberration of the eye after cataract surgery and to obtain better visual quality.However,the selection of a personalized aspheric IOL is a problem to be solved.Objective This study was to compare the wavefront aberration and quality of vision of patients between the implantation of negative spherical aberration IOL and non-aberration IOL,and to investigate the relationship between corneal Q values and postoperative spherical aberration.Methods One hundred and four eyes of 90 patients with age-related cataract were randomized into two groups.Fifty-two eyes of 46 patients who received a Tecnis Z9001 IOL implantation were assigned as the negative spherical aberration IOL group and 52 eyes of 44 patients who received Akreos AO IOL without aberration were assigned as the non-aberration IOL group.The preoperative corneal Q values were measured and the mean Q value(Q)was computed.Then the patients in the two groups were further divided into 2 subgroups,respectively,based on their Q values were over or below (Q）.The corneal Q values,root mean square(RMS) of ocular spherical aberration,coma and total higher-order aberrations(HOAs) for 5 mm diameter pupil,scotopic contrast sensitivity with or without glare at 6 mm pupil diameter were measured 3 months after surgery.Results The pre-and post-operative corneal Q values were insignificantly changed (t =1.447,P =0.151).The spherical aberration in the negative spherical aberration IOL group was(0.059-±0.047)μm,and that in the non-aberration IOL group was(0.110±0.066)μm,with a statistically significant difference between them (t =-4.567,P=0.000).Scotopic contrast sensitivities at intermediate and high frequencies were significantly better in the negative spherical aberration IOL group than in the non-aberration IOL group (t =2.495,t =2.359,P ＜ 0.05).There was no significant difference in coma and HOAs between the two groups after operation (P ＞ 0.05).Weak positive correlations were seen between the pre-and post-operative corneal Q values and spherical aberration in the two groups(r=0.277,0.292,0.285,0.325,all at P＜0.05).However,no significant differences were found in spherical aberration,contrast sensitivity and scotopic contrast sensitivity between the different subgroups (P ＞ 0.05).Conclusions Negative spherical aberration IOL has lower spherical aberration and better scotopic contrast sensitivity than non-aberration IOL.The results suggest that it may be not enough to choose the corneal Q value only as the single reference criterion for selection of aspheric IOL.

Objective To investigate the teaching effectiveness of preventive medicine and ask the students for feedback on the curriculum in order to reform the teaching methods.Methods Questionnaire survey.Sampling survey.Results 89.2％ of students have realized the importance of preventive medicine.Respectively 16.4％ and 7.5％ of students have no interesting on the curriculum due to teachers'matter and students' idea that the course is uselessness for their major and future career.75.1％ of students are interest in Nutrition and Food Hygiene,35.2％ of students dislike Medical Statistics,and 45.3％ of students think the most tough part is Medical Statistics.78.9％ of students wish to have more practice lessons.30.5％ of students do not ask teachers questions because of no communication with teachers after class.Conclusions Preventive Medicine is still ignored by a few students.The more tough the content is,the less interest the students have. Repeatedly emphasizing the importance of Preventive Medicine in medical education,adopting and combining with the community practical cases in class lectures and frequently communicating between teachers and students after class are suggested.
