AIM: To study the effects of body position on the physiological and pathological changes in an oleic acid-induced acute lung injury (ALI) model. METHODS: One control group and three experimental groups were set up in which the rabbits were put on supine, prone and rotation, respectively. The changes of blood pressure, heart rate and partial pressure of arterial oxygen, lung mechanics, cytokines in the course of experiment and pathologic changes were observed. RESULTS: At the end of experiment, heart rate in rotated rabbits was lower than that in prone rabbits [(176.13?26.55) beats/min vs (217.75?14.44) beats/min, P

Objective To analyze the allele frequencies of 5 short tandem repeat(STR)loci(D12S313,D12S304,D12S1640,D12S1708 and D12S1583)on chromosome 12 among Kashin-Beck disease(KBD)patients and the control population living in the area suffered from KBD.Methods Fifty KBD patient8 and 50 non-KBD patients were chosen in endemic afea of Shaanxi Province,5 STR loci on chromosome 12 were genotyped by the technology of polymerase chain reacfion(PCR)and capillary electmphoresis.The pelymorphisms of STR in these popIllations were analyzed.The allele and genotype frequencies of each STR in the corresponding groups were caleulated and compared. Results In KBD group,the 5 STR loci had 8,6,7,5 and 11 types ofalleles and 17,11,15,8 and 28 genotypes, respectively;while in the control group,the number of aUele types of 5 STR loci were 6,8,6,4 and 10,the number of genotype of those loci were 13,21,14,8 and 23,respectively The allele frequence of D12S304 locus was statiBtically significant between KBD patients and controls(P<0.05),especially for the 319 bp allele(P<0.006 25). Conclusion There is an association between D12S304 locus and KBD.The 319 bp allele might play the key role.

·AIM:To report a case of entry of antibiotic ointment into the anterior chamber following sutureless clear corneal incisions phacoemulsification.·METHODS:A 62-year-old man had uneventful phaco-emulsification with clear corneal incisions with intraocular lens(IOL) implantation. Postoperative medication included antibiotic/steroid ointment; the eye was firmly patched at the end of the procedure. On the first postoperative day, the patient was seen an oily droplet floating in the anterior chamber. Immediate surgical removal of the ointment without IOL exchange was performed.·RESULTS:During follow-up for six months after irrigation/aspiration of the anterior chamber and removal of the oily droplet, visual acuity and intraocular pressure (IOP) were unchanged and anterior segment was formed and quiet.·CONCLUSION:Ophthalmic ointment may ingress into the anterior chamber through unstable clear corneal incisions. The case highlights the importance of appropriate wound construction and integrity, as well as the risk of tight eye patching following placement of ointment.

Objective The aim of this paper is to know about the pollution of microcystin-LR(MC-LR)in Fenhe First reservoir and Fenhe Second reservoir in Taiyuan and provide reference for making the policy of prevention microcystin-LR pollution.Methods During the low water period(May,2005)and common period(Oct,2005),5 liter water was sampled in the entrance,the center and the exit in Fenhe First reservoir and Fenhe Second reservoir respectively.The concentrations of MC-LR in two reservoirs were determined by the high-performance liquid chromatography(HPLC).Results The average concentration (0.875 ?g/L)of MC-LR in low water period was 3 time of that(0.283 ?g/L)in common period in Fenhe First reservoir.The average concentration(0.815 ?g/L)of MC-LR in low water period was 17 time of that(0.048 ?g/L)in common period in Fenhe Second reservoir.The level of MC-LR in the entrance was the highest,that in the exit was the lowest,that in the center was middle. The concentration of MC-LR of the entrance in low water period was more than the MC-LR limit(1 ?g/L)in Life drinking water hygienic guide(2001).Conclusion MC-LR pollution has been found in Fenhe First reservoir and Fenhe Second reservoir and the pollution is serious in low water period.

Objective To explore the mechanisms of posterior pilon fractures and evaluate the curative effects of different types of fixation on the treatment of posterior pilon fractures.Methods We included in this retrospective study 20 patients with posterior pilon fracture who had been treated from January 2012 to January 2015 at our department.They were 10 men and 10 women,from 23 to 77 years of age (average,50.6 years).According to the classification by Yu Guangrong,5 cases belonged to type Ⅰ,3 to type Ⅱa,4 to type Ⅱb,and 7 to type Ⅲ.One was not indentified because of lacking CT examination.The mechanisms included ground level fall in 2 cases,motor vehicle accident in 7,fall off stairs in 5,sport injury in 2,fall from a bike in one and fall from a height in 3.More than 25% of the articular surface was involved in 13 patients.Syndesmosis injury was identified in 6 patients by Cotton test during operation.Internal fixation varied accordingly.We recorded the mechanism,classification,proportion of the articular surface involved (more or less than 25%),and syndesmosis injury to figure out the characteristics of posterior pilon fractures.We used the Burwell-Charnley radiographic criteria to assess the postoperative reduction of the articular surface,and the Olerud-Molander scoring scale and visual analogue scale (VAS) to assess the ankle function.The curative effects of different types of fixation on the treatment of posterior pilon fractures were compared.Results Of the 20 patients,17 were available for follow-up for 6 to 36 months (average,17.8 months).Two patients received reoperation because of implant failure after cannulated screw fixation from anterior to posterior.The Burwell-Charnley radiographic evaluation revealed 12 anatoinical reducations and 8 fair reductions.The mean Olerud-Molander score for the 17 patients at the final follow-ups was 81.5 (range,from 35 to 100) and the mean walking VAS was 1 (from 0 to 3).Conclusions Posterior pilon fractures are mostly caused by medium to high energy violence,resulting from a combination of rotational and vertical forces.Since there is a high risk of implant failure,the cannulated screw fixation from anterior to posterior is not recommended.Good clinical outcomes are observed in the cannulated screw fixation from posterior to anterior and the plate/cannulated screw fixation for posterior pilon fractures.

Objective To conduct a meta?analysis of literatures to explore the relationship of UGT1A1*6 gene polymorphism and irinotecan toxici?ty,so as to guide clinical treatment. Methods Papers were searched by PubMed database and manual search. The inclusion and exclusion criteria of studies were formulated and the methodologies quality was assessed,data were extracted and the statistical analysis was made using STATA12.0 software. Results A total of 12 articles were included according to the inclusion and exclusion criteria. Patients with mutated UGT1A1*6 showed an increased risk for neutropenia compared to wild UGT1A1*6(OR=2.37,95%CI 1.58?3.55,P=0.001). Both homozygous and heterozygous muta?tion showed an increased risk for neutropenia compared to wild type and the homozygous mutation(OR=5.09,95%CI 2.74?9.45,P<0.001) showed an even higher risk for neutropenia compared to the heterozygous mutation(OR=2.07,95%CI 1.37?3.13,P=0.001). For severe diarrhea, mutated UGT1A1*6 showed an increased risk compared to wild type(OR=1.48,95%CI 0.86?2.55,P=0.153),though without statistical signifi?cance. The homozygous mutation performed a significantly increased risk(OR=3.51,95%CI 1.33?9.25,P=0.011)and the heterozygous mutation also showed increased risk,however,the difference between them was not statistically significant. Conclusion UGT1A1*6polymorphisms can pre?dict irinotecan toxicity,especially for incidence of neutropenia.
