Objective To investigate the life quality of children with intractable epilepsy and observe the effect of psychological intervention on them.Methods Thirty-nine children with intractable epilepsy,42 children with drug respond epilepsy and 40 healthy children were employed and tested by using of the child self-report scale of quality of life for children with epilepsy.Scores of quality of life were compared among 3 groups.Children with intractable epilepsy were divided randomly into 2 groups:psychological intervention group(19 cases)and non psychological intervention group(20 cases).Only drug treatment was given in non psychological intervention group,drug treatment and psychological intervention were given in psychological intervention group,quality of life was valuated before and 1 month after psychological intervention,then scores of quality of life were compared after and before psychological intervention in psychological intervention group,total scores of quality of life were compared between psychological intervention group after and before psychological intervention and non psychological intervention group.Results Compared with children with drug respond epilepsy and healthy children,the children with intractable epilepsy had lower scores of quality of life(Pa

Kinematical alignment during total knee arthroplasty is an emerging process, and draws more and more attentions from scholars. Knee joint is close to normal joint after TKA through kinematical alighment, which has good clinical results and functional scores, and not increase failure probility. Thus, it may increase joint stress of patella-femur joint, lead to patellar maltracking and increase abrasion. The paper summarized defination and basical principle, operative method, clinical outcomes and deficiency of kinematical alignment during total knee arthroplasty, in order to choose a better way for kinematical alignment during total knee arthroplasty.

A high performance liquid chromatography-electrospray ionization mass spectrometry- charged aerosol detection ( HPLC-MS-CAD) method was established for the simultaneous quantitative analysis of four Lignans in Magnoliae Flos extract. The components were separated on a YMC-Pack ODS-A column (250 mm× 4. 6 mm, 5 μm) by gradient elution with methanol and water as the mobile phase at aflow rate of 1. 0 mL/min. Then the elution solution was routed into MS equipment at a flow rate of 0. 3 mL/min and CAD detector at a flow rate of 0. 7 mL/min by a split ratio of 3:7 for the further detection. The column temperature was 25 ℃ and the detection wavelength was 278 nm. A method was developed for the quantitative analysis of muti-components by single maker ( QAMS) to determine pinoresinol dimethylether, magnoli, 1irioresinol B dimethylethe and epi-magnoli A . Magnoli was selected as internal standard and the relative correction factors ( RCF) of the four Lignans were calculated. The contents of the four Lignans in Magnoliae Flos extract were determined by both external standard method and QAMS. The QAMS method was evaluated by comparison of its assay result and that of external standard method. Under the selected chromatographic condition, the limits of detection of pinoresinol dimethylether, magnoli, lirioresinol B dimethylethe and epi-magnoli A were 0. 34, 0. 55, 0. 50 and 0. 58 mg/L, respectively, while the linear range were within 6. 8-270 mg/L, 11-546 mg/L, 2. 0-101 mg/L and 2. 3-116 mg/L. The recoveries ( n=9 ) were 98. 2%-99. 5%, and the correlation coefficient were 0 . 9995-0 . 9998 . No significant differences were found between the quantitative results of external standard method and QAMS method. The developed method is accurate, feasible, and can be used for quality evaluation of Magnoliae Flos .

Leucine zipper tumor suppressor 2 (LZTS2) is a novel tumor suppressor gene that has been increasingly recognized in recent years. Currently, many studies illustrate that LZTS2 gene, the important candidate tumor suppressor gene, is already involved in the inhibition of tumorigenesis and aberrant proliferation of tumor cells, and other functions of tumor cells. Information from these stud-ies can contribute to the formulation of new strategies for the treatment of tumors.

AIM:To observe and compare clinical effects of coaxial 1. 8mm microincision phacoemulsification and 3. 2mm small incision phacoemulsification.
●METHODS:A total of 117 eyes of 85 patients with age-related cataract in our hospital were divided randomly into two groups:43 patients (59 eyes) in the coaxial 1. 8 mm microincision cataract surgery group ( C - MlCS ) , 42 patients (58 eyes) in the coaxial 3. 2 mm traditional small incision cataract surgery group (C-SlCS). A total of 117 eyes were received phacoemulsification with intraocular lens implantation. Uncorrected visual acuity was recorded preoperatively and postoperatively at 1, 7, 30 and 90d. The effective phacoemulsification time and average ultrasound energy were recorded in surgery. Corneal endothelial cell and corneal topography were recorded preoperatively and postoperatively at 90 d.
●RESULTS:Uncorrected visual acuity ( logMAR) was no overall statistical significance difference between C-MlCS group and C-SlCS group (P>0. 05), but was significant statistical difference in different time-point within both groups(P<0. 05). Uncorrected visual acuity in different time-point had nothing to do with corneal wound size in cataract surgery(P>0. 05). On the 1 day after surgery, uncorrected visual acuity was 0. 16±0. 11 in C-MlCS group and 0. 22±0. 18 in C-SlCS group(P<0. 05). AVE was (7. 00± 2.72)% in C-MlCS group and (6. 16±3. 16)% in C-SlCS group (P>0. 05). EPT was (3. 09±1. 61)s in C-MlCS group and (3. 20±1. 92)s in C-SlCS group (P>0. 05). At 90 d after surgery, corneal endothelial cell loss percentage was (5. 81±2. 28)% in C-MlCS group and (5. 69±2. 38)% in C-SlCS group (P>0.05), SlA was (0.35±0.11) Din C-MlCS group and (0. 61±0. 13) D in C-SlCS group (P<0. 05).
● CONCLUSION: Compared with coaxial 3. 2mm traditional small incision cataract surgery, 1. 8mm coaxial microincision cataract surgery can get earlier visual rehabilitation and significantly reduce SlA. The coaxial 1. 8mm microincision cataract surgery is safe, effective and deserves further clinical applications.
