To compare the impact of different incision positions of phacoemulsification cataract exaction on corneal astigmatism.
●METHODS: Totally 412 patients ( 456 eyes) who had undergone the phacoemulsification and lOL implantation from June 2006 to June 2013 were randomly divided into two groups (each 228 eyes): observation group (incision above the middle of the limbus for the rule astigmatism, at the temporal for against the rule astigmatism, at the top of the temporal regulation on the maximum curvature of the meridian of the cornea for oblique astigmatism, at the top of the temporal for patients without astigmatism);control group ( incision at top and middle of limbus), using a 3mm cornea scleral tunnel incision without suture, 2mm from the limbus. Corneal refractive status of preoperative and postoperative at different times were detected by corneal refractive, comparing the impact of different surgical incision on postoperative corneal astigmatism.
●RESULTS:The visual acuity of 1, 3mo postoperative of observation group was significantly better than the control group ( P < 0. 05 ). The average astigmatism of 1, 3mo postoperative of observation group was significantly lower than the control group ( P < 0. 05). Corneal astigmatism 3mo postoperative of observation group was significantly lower than preoperative ( P< 0. 05). Corneal astigmatism 3mo postoperative of control group was significantly higher than preoperative (P<0. 05).
●CONCLUSlON:lncision at the corneal curvature of the largest radial could correct preoperative astigmatism and improve visual acuity to a certain extent.

Conclusion Dynamic picture angiography with digital subtraction using non-ionic contrast medium under rapid injection is the key for claiming the high quality imaging diaguosis of congenital heart disease in children.

Objective To observe the clinical therapeutic effect of benazepril plus betaloc in the treatment of chronic congestive heart failure(CHF).Methods 42 cases with CHF were treated with benazepril plus betaloc,the therapeutic effect was compared with 40 cases treated with benazepril alone.Before and after treatment,to observe the changes of systolic pressure(SBP),diastolic pressure(DBP),heart rate(HR),left ventricular end systolic diameter(LVESd),left ventricular end diastolic diameter(LVEDd) and left ventricular ejection fraction(LVEF) were observed.Results The general effective rate in treatment group and control group was 95.2% and 80.0%,respectively.The SBP,DBP,HR,LVESd and LVEDd in treatment group decreased obviously(P

Objective The dynamic accumulation trend of secondary metabolite in cultivated Spatholobus suberectus Dunn at different growth time was studied to provide scientific basis for confirming its reasonable harvesting time. Methods Ethanol-soluble extractives were measured by the method recorded in Chinese Pharmacopoeia ( A) Appendix XA ( 2010 edition). The content of total flavonoids was tested by ultraviolet spectrophotometer. The contents of protocatechuic acid, catechin, and epicatechin in Spatholobus suberectus Dunn were determined by high performance liquid chromatography ( HPLC). Results The contents of ethanol-soluble extractives, total flavonoids and the major components such as protocatechui cacid, catechin and epicatechin in Spatholobus suberectus Dunn showed increasing trend with the prolongation of growth time. The changes of contents of alcohol-soluble extract, total flavonoids and epicatechin in samples collecting at different months in one year showed a parabolic trend, and the contents reached the peak values from July to September. Catechin content kept increasing continually. The content of ethanol -soluble extractives of Spatholobus suberectus Dunn aged 4-6 years met the requirements of the current edition of Chinese Pharmacopoeia when harvested from July to September. Conclusion It is preliminarily recommended that Spatholobus suberectus Dunn cultivated for more than 7 years is suitable for harvesting, but the optimal harvest period and the harvest month still need to be further studied.

Objective To understand the relationship between the requirement and the consumption of the health management, and provide the theoretical basis for the developing of China health management. Methods It took the survey to understand the relationship among 152 medical staffs from the six counties surrounding with Shi Jiazhuang downtown. Results 85.5%of medical staffs always and almost accept health advisory and provide health guidance. There are not the direct relationship between the requirement and the consumption(x2 = 9.39,P＞0.05 ). Health advice and guidance are not translated into the concepts of investment on the health management and disease prevention (x2 = 1.69, P＞0.05 ). The medical staffs don't realize it is important to invest on the health. Conclusions Related industries should strengthen the training on the health management, publicize this profession, promote the development of health management services and improve the national health quality.[ Key words] Health promotion ; Needs assessment; Economics

Objective To investigate the impact of metal plate on radiation dose distribution in surrounding tissues in cadaver specimens.Methods Stainless steel plate, titanium plate, and muscle strip were implanted into the left thigh of a corpse, respectively.All the specimens were irradiated with 6 MV X-ray , SSD = 100 cm.The absorbed dose of surface was measured by thermoluminiscent elements.Results Surface dose distributions differed significantly among the three different materials (F = 57.35, P < 0.01),with the amounts of 1.18 Gy ± 0.04 Gy (stainless steel plate), 1.12 Gy ± 0.04 Gy (titanium plate) and 0.97 Gy ±0.03 Gy (muscle strip), respectively.The surface absorbed doses on incident plane of stainless steel plate and titanium plate were significantly increased by 21.65% and 15.46% respectively as compared with that of muscle strip.The absorbed doses on the exit surface of stainless steel plate, titanium plate and muscle strip were 0.87 Gy ± 0.03 Gy, 0.90 Gy ± 0.02 Gy and 0.95 Gy ± 0.04 Gy, respectively (F =13.37, P <0.01).The doses on the exit surface of stainless steel plate and titanium plate were significantly lowered by 8.42% and 5.26% when compared with that of muscle strip.Using treatment planning system,the differences between dose distribution with and without metal plate were compared.Within 1 cm away from the incident plate, there was an obvious increase in the absorbed dose, while the influence was less than 5% 1cm outside the surface.The effect of dose distribution on exit surface was less than 2%.Conclusions The influence of metal plate on the radiotherapy dose distribution is significant.The deviations ranges from 5% to 29%.Under the same condition, the impact of stainless steel plate is much more than that of titanium alloy plate.

Objective To analyse the mutation of K17 gene in a pedigree with steatocystoma multi-plex. Methods Blood samples were obtained from 3 affected and 3 normal individuals in a family with steatocystoma multiplex, as well as from 50 unrelated healthy individuals. Mutation scanning was carried out by PCR and direct sequencing. Results A heterozygous nucleotide transition (C→T) at position 428 in exon 1 of KI7 gene, which leads to the substitution of CGC (arginine) by TGC (histidine) at codon 94, was detected in the affected individuals, but not in normal family members or the 50 unrelated individuals. Conclusion A missense mutation (428C→T) in KI7 gene has been detected in affected individuals of this family, which seems to be a molecular basis of pathogenesis of steatocystoma multiplex.
