Abstract?AIM: To analyze the effects of femtosecond laser assisted cataract surgery ( FLACS ) in the treatment of cataract and its effect on prognosis.?METHODS:Forty-two cases (42 eyes) of patients with cataract who were treated in the Department of Ophthalmology in our hospital between January 2012 and December 2014 were selected as the study objects. According to the order of treatment, they were divided into control group and observation group, 21 cases in each. The control group was treated with traditional phacoemulsification cataract surgery ( PCS ) . On the basis, the observation group was treated with femtosecond laser. The effective phacoemulsification time (EPT), cumulative dissipated energy (CDE), fluid flow and monitored pressure of the two groups were recorded.The rate of corneal endothelial loss and the situation of Tyndall phenomenon were statistically analyzed.The two groups were followed up for 1a.The long-term visual acuity recovery was observed.The best corrected visual acuity ( BCVA ) was recorded, and the long-term complications were statistically analyzed.?RESULTS: 1 ) The total response rate in observation group was 95% while in control group was 90% ( P>0.05);2) the surgery time of the observation group was longer than that of the control group ( P<0.05) but EPT was shorter than that of the control group.CDM and liquid flow were less than those of the control group ( P<0.05 ); 3 ) at 1d after surgery, there was no significant difference in intraocular pressure between the two groups (P>0.05); the rates of Tyndall phenomenon and corneal endothelial loss in the observation group were lower than those in the control group ( P<0.05);4) BCVA of the two groups at different time after surgery were significantly higher than that before surgery (P<0.05). However, at 1d, 3mo, 6mo and 1a after surgery, BCVA of the observation group was better than that of the control group ( P <0.05 ); 5 ) the incidence of complications in the observation group after surgery (14%) was lower than that in the control group (43%) (P<0.05).?CONCLUSION: The surgical effects of FLACS in the treatment of cataract are good.After surgery, the visual acuity of patients is improved significantly and the incidence of postoperative complications is low. However, the surgery time is long and cost is high, so it is difficult to popularize.

Objective To investigate new cases of endemic cretinism in high-risk areas of Inner Mongolia, the prevalence of endemic goiter, the implementation of comprehensive measures, and to provide scientific basis for developing control strategies against iodine deficiency disorders (IDD). Methods In 2007 and 2008, a search for new cretin cases was conducted among children under the age of 10 in 11 historical serious epidemic cretinism prevalent areas of Songshan district, Keshiketeng qi, Kalaqin qi, Zhalaite qi, Zhuozi county,Liangcheng county, Qingshuihe county, Helin county, Dongsheng district, Zhungeer qi and Yinjinhuoluo qi. Three to 5 towns were selected in each qi(county, district) and 3 to 5 village primary schools were selected in each town.One hundred and twenty to 200 children aged 8 to 10 were selected in each school to inspect thyroid by B ultrasound and palpation and to test intelligence and urinary iodine. Two villages were selected in each town and 30 households were selected to determine urinary iodine of housewives and salt iodine. Results A total of 56 cases of suspected cases of endemic cretinism were found from the 11 counties but no case was confirmed. The goiter rate of children aged 8 to 10 was 5.2% (309/5922) by palpation and 4.3% (252/5922) by B-ultrasound. The median urinary iodine of children aged 8 to 10 was 241.5 μg/L, and urinary iodine was 100 to 300 μg/L, accounted 65.9%(3901/5920). Median urinary iodine of the 9 Qis(counties, districts) was in the range of 200 and 300μg/L.Higher than 5% of the 11 Qis(counties, districts) with urinary iodine lower than 50 μg/L was zero. Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 1. The median urinary iodine of housewives was 225.6 μg/L, and lower than 50 μg/L accounted for 2.2%(35/1597). Higher than 10% of the 11 Qis(counties, districts) with urinary iodine lower than 100 μg/L was 4. A total of 2109 households were investigated and 97.45%(2055/2109) of them ate iodized salt and 2.55%(54/2109) of them ate non-iodized salt. Conclusions In the 11 investigated counties, goiter rate of children has decreased to less than 10%, and no new cretin was found. It could be concluded that the fulfillment of prevention and control of IDD is effective. The iodine nutrition of children and women of childbearing age is in an adequate level. The coverage rate of iodized salt has maintained at a higher level, the sales network is sound, the salt price is reasonable and salt is easy to get and the children's intelligence is protected effectively. But, the health education about IDD is still weak, need to be reinforced.

Objective:To investigate the effects of Porhyromonas endodontalis(P.e)liopolysaccharide(LPS)on the expression of IL-23mRNA and protein in mouse osteoblasts MC3T3-E1 and the role of phosphatidylinositol 3-Kinases (PI3K)signaling pathway in this process.Methods:MC3T3-E1 cells were treated with different concentrations of P.e LPS for different hours,or pretreated with LY294002,a special PI3K inhibitor.The IL-23 mRNA and protein expression levels were detected by real-time PCR and Western blot respectively.Results:The level of IL-23 mRNA increased in MC3T3-E1 cells with the increase of concentration and the treatment time of P.e LPS(P <0.05).The IL-23 protein expression was increased by P.e LPS in a time dependent manner(P <0.05).The mRNA and protein of IL-23 decreased(P <0.05)after pretreatment with LY294002.Conclusion:P.e LPS can induce the expression of IL-23 mRNA and protein in MC3T3-E1 cells,and the PI3K signaling pathway may play a part in this process.

Objective To investigate the role of fibroblasts in nonunion fracture healing using extracorporeal shock wave(ESW) treatment. Methods Thirty healthy rabbits were selected to make the models of non-union fractures of the right tibias, which were then held apart by external fixation. 12 weeks after the operation, hypertrophic non-unions were confirmed in 27 of the rabbits by radiography. These 27 were divided randomly into a treatment group and a control group. The test animals were treated with ESW under general anaesthesia. The two ends of the nonunion fracture were shocked 1 000 times at 0.54 mJ/mm2 and a frequency of 60 times/minute. The nonunions of the control group were treated with external fixations only. Histological examination and transmission electron microscopy(TEM) were conducted after 2 and 6 weeks. Standardized radiographs were taken after 12 weeks of the shock wave treatment. Results ESW induced microfractures, which initiated the healing process of the nonunionfractures. X-rays showed that 8 of the 9 fractures of the treatment group had healed after 12 weeks of EWS treatment, but only 3 of the 9 in the control group had healed. Statistical analysis showed that this difference was significant at the 5% level. After 2 weeks of ESW treatment, TEM showed many collagen fibers around the fibroblasts in the treatment group, with characteristic and periodic transverse lines. This indicated that the fibroblasts had been secreting collagen fibers as osteoblasts. Six weeks later, osteoblasts and fibroblasts had formed bone lacunes, and they had become osteocytes. However osteogenetic activates were not found in the control group. Conclusions Fibroblasts are activated by ESW to better form bone tissue. This process plays an important role in rebuilding broken bones.

OBJECTIVE To investigate the effect of quercetin on primary cultured newborn rat cortex neuron cell which is estrogen depletion, and discuss the possible mechanism, to provide new ideas and strategies for developing a drug of neurodegenerative disease. METHODS Rat cortex neurons were isolated from one day old Sprague Dawley rats and treated with estrogen, quercetin and estrogen receptor antagonists (ICI182,780). Cell viability was determined by MTT assay, neurite outgrowth was measured by fluorescent microsope and estrogen receptors were determine by Western blot. RESULTS Quercetin functions like estrogen to increase cortex neuronal cell viability, the Que (50, 100 μmol·L-1) group compared with the control group could significantly improve the activity of the cortical neurons(P<0.05). It can also increase neurite out growth, the Que (50,100 μmol·L-1) group significantly promoted the formation of synapse, most of the neurons were full, and the synapses of neurons became thick, growth, and connect to a dense neural network. And in the Western blot experiments, Que (50, 100 μmol·L-1) group could obviously increase the expression of estrogen receptor alpha protein, in addition, the neural protective effect of quercetin can be inhibited by ICI182,780. CONCLUSION Quercetin like estrogen can protected cortex neuronal and the effect of quercetin on cortex neuronal cells was mediated by estrogen receptor alpha.
