·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 To investigate the association of lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms with metabolic syndrome among Kazakh and Han ethnicities in Xinjiang.Methods PCR-RFLP was used to detect 802 subjects' lipoprotein lipase Hind Ⅲ and S447Xgenotypes (including 201 controls and 200 metabolic syndrome patients in Kazakh and Han ethnicities, respectively). Results (1) Frequencies of H + H-/H-H- genotype (32.50% vs.47.76%), H- allele( 18.00% vs. 28.86%), SX/XX genotype (8.00% vs. 22.39%) and X allele (4.00%vs. 12.44% ) for metabolic syndrome in Hah ethnicity were all significantly lower than those in controls (P＜ 0.01 ). (2) The frequencies of H + H-/H-H- genotype (33.50% vs. 46.80% ), H- allele (22.00% vs. 28.60%), SX/XX genotype (10.50% vs. 22.90%) and X allele (5.50% vs. 12.44% ) in patients with metabolic syndrome in Kazakh were all significantly lower than those for controls (P＜0.01). (3) The frequencies of lipoprotein lipase gene Hind Ⅲ and S447X genotypes and alleles in Kazakh were not significantly different from Han (all P＞0.05). (4)The levels of waist circumference, systolic blood pressure, diastolic blood pressure, triglyceride and FPG in H + H-/H-H- and SX/XX genotype were significantly lower than those in H + H + and SS genotype.HDL-C was significantly higher than that in H + H + and SS genotype (P＜0.05). (5) The frequencies of H + H + and SS genotype increased along with the increase in number of metabolic syndrome component. Conclusion The lipoprotein lipase gene Hind Ⅲ and S447X polymorphisms were associated with metabolic syndrome risk in Kazakh, and H + H-/H-H- genotype, H- allele, SX/XX genotype and X allele might have served as protective factors of metabolic syndrome. H + H-/H-H- and SX/XX genotype seemed to have had beneficial effects for all the metabolic syndrome components, and the frequencies of H + H + and SS genotype were increasing along with the increase of number in the metabolic syndrome components.

This study was aimed to investigate the effect of baicalin on proliferation and apoptosis of HL-60 cells and its mechanism. Cell proliferation was assayed by using Cell Counting Kit-8. The morphological changes of HL-60 cells were examined by light microscopy and nucleolus morphological changes were observed by fluorescent microscopy after Hoechst 33342 staining. The early cell apoptosis was detected by using flow cytometry with Annexin V-FITC/PI double staining. The expression of caspase-3, caspase-9, Bcl-2 and Bax mRNA was detected by RT-PCR and Western blot assay was carried out to examine Bax, Bcl-2, caspase-8 and cleaved caspase-3 expression. The results showed that Baicalin inhibited the proliferation of HL-60 cells in a time- and concentration-dependent manner. HL-60 cells exhibited typical morphological features (for example, cell shrinkage, membrane blebbing and formation of apoptotic bodies). Cell apoptosis in early stage could be detected, the expression of caspase-3, caspase-9 and Bax mRNA was obviously up-regulated, while the Bcl-2 expression down-regulated, and accordingly Bcl-2/Bax ratio decreased. Such results were consistent with the expression of these proteins. In addition, the expression of cleaved caspase-8 protein was induced significantly after treated with baicalin. It is concluded that baicalin can significantly inhibit the proliferation of HL-60 cells and induce the apoptosis of HL-60 cells, which may occur through decreasing Bcl-2/Bax ratio by intrinsic pathway and through extrinsic pathway. It suggests that baicalin may be a promising drug for the therapy of acute myeloid leukemia.

Objective To analyze the prevalence of metabolic syndrome (MS) in Kazakh population, using the NCEP-ATP Ⅲ, CDS, IDF MS standards. Methods Questionnaire-based survey,physical examination and blood testing were conducted according to cluster random samplings in Kazakh residents in Xinjiang. 2745 samples were collected and diagnosed by NCEP-ATP Ⅲ, CDS,IDF standards to analyze the prevalence, with the distribution of its main components of MS, among the Kazakhs population. Results The prevalence rates of MS diagnosed by NCEP-ATP Ⅲ, CDS,IDF standards were 18.5%, 14.2% and 26.6%, while they became 14.2%, 10.9% and 20.1% after standardized by age. The prevalence of MS diagnosed by NCEP-ATP Ⅲ and IDF standard in males were higher than in females, while CDS was in the opposite situtation. The prevalence of MS by these three standards increased with age. Among all the main components of MS diagnosed after these three standardization process, the prevalence of obesity, blood pressure rising and the abnormity of HDL-C were rather high. The prevalence of MS main components ≥1, ≥2, ≥3, ≥4, 5 ranked the highest compared to the lowest as to the IDF, ATP Ⅲ ' and CDS diagnostic. standards Conclusion The prevalence rates and gender distribution of MS diagnosed by different standards among Kazakhs were different. The prevalence of IDF standard was the highest, with the IDF standard better than the others in early identifying the risk factors of cardiovascular disease.

OBJECTIVETo investigate the failure mechanisms of revision hip arthroplasties and evaluate the effects of surgical technique, prosthesis design and patient-related risk factors on different failure mechanisms.

METHODSA review of all revision hip arthroplasties from November 1995 to June 2008 identified 30 patients who underwent 30 revisions with 18 males and 12 females. The overall mean age for primary arthroplasties was 49 years (range 25-68 years) and 53 years (range 27-72 years) for index revision arthroplasties and the average interval between these two operations was 43.8 months (0-156 months). The failure mechanisms of index revision arthroplasties and primary arthroplasties were assessed and compared. Direct comparisons were made of data for the different age categories in terms of time to failures and reasons for failures.

RESULTSRegarding revision or prosthesis removal as the end point of the study, the reasons for 30 revision arthroplasties were aseptic loosening in 22 hips (73.3%), infection in 4 hips (13.3%), periprosthetic fracture in 3 hips and instability in 1 hip (3.3%). The overall mean age for last arthroplasties or prosthesis removal was 58 years (range 38-77 years) with an average interval of 78.8 months (range 1-216 months) from previous revision arthroplasties. The mean time to failure for patients above 60 years of age was significantly shorter than patients below 60 years of age (P < 0.01).

CONCLUSIONThe majority of failure mechanisms of revision hip arthroplasties are ineffective fixation of revisional implants and recurrence of local infection, which reveals the limitations to joint reconstruction philosophy and surgical technique.

OBJECTIVETo evaluate the short-term outcomes of patients receiving orthopedic surgery with posterior pedicle screw fixation for degenerative lumbar scoliosis.

METHODSBetween March, 2006 and August, 2009, 36 patients with degenerative lumbar scoliosis (19 males and 17 females) underwent procedures of decompression, bone implantation and pedicle screw fixation. Fifteen patients were also treated by PLIF and 21 cases received posterior-lateral fusion. The JOA scores, Oswestry disability index (ODI), and Cobb angle were recorded before and after the operation, and the surgical complications were also observed.

RESULTSThe JOA scores increased significantly by 83.3% after the operation (P<0.05). The procedures resulted in significantly lowered ODI from (67.1∓11.4)% before the operation to (32.1∓10.8)% after the operation (P<0.01). A significant improvement of the coronal Cobb's angle was achieved after the operation (26.7° preoperatively vs 12.3° postoperatively, P<0.01), and the lordosis angle was improved from 10.7° to 36.6° after the operation (P<0.01). All the patients were followed up for 12 to 50 months (mean 38 months), and no implant loosening, displacement or fragmentation, or pseudarthrosis was found at the final follow-up.

CONCLUSIONPosterior pedicle screw fixation shows good short-term therapeutic effect in treatment of degenerative lumbar scoliosis. Individualized surgical plans and adequate preoperative evaluation are keys to successful operations.
