AIM: To observe the tear film changes after phacoemulsification combined with intraocular lens implantation in age - related cataract patients and to compare the therapeutic effect of hydroxyl-glucoside and sodium hyaluronate on the postoperative dry eye.
METHODS:A total of 49 patients ( 70 eyes ) with age-related cataract suffering from dry eye after phacoemulsification combined with IOL implantation were divided into treatment group 1 ( group A, 23 eyes with conventional therapy and hydroxyl - glucoside at 7d postoperatively) , treatment group 2 ( group B, 22 eyes with conventional therapy and sodium hyaluronate at 7d postoperatively) and control group ( group C, 25 eyes with conventional therapy only ) . Questionnaire score of dry eye symptoms, SchirmerⅠtest ( SⅠt) , tearfilm break up time ( BUT ) and corneal fluoresce in staining ( CFS ) were measured at 2d preoperatively and 7, 14, 30, 90d postoperatively.
RESULTS: No statistical differences existed among the three groups of preoperative 2d ( P > 0. 05 ). At 2d preoperatively and 90d postoperatively, the results of questionnaire score of dry eye symptoms, SⅠt, BUT, and CFS displayed no statistical differences in the patients of three groups (P>0. 05). While there was statistical significance among preoperatively and 7, 14, 30d postoperatively of the three groups (P<0. 05). At 14, 30d postoperatively, the questionnaire score of dry eye symptoms, SⅠt, BUT, CFS in group A and B were better than in group C, which displayed statistical differences ( P<0. 05). At 30d postoperatively the questionnaire score of dry eye symptoms , SⅠt, BUT in group B were better than in group A, which displayed statistical differences ( P<0. 05).
CONCLUSION: At the early stage after phacoemulsification combined with IOL implantation, the tear film stability is decreased, which may promote eyesymptoms. Management with hydroxyl-glucoside or sodium hyaluronate plays a role in relief of the structure and stability of the tear film and improves dry eye symptoms, while sodium hyaluronate eye drops is more effective.

To obtain single chain variable fragment (scFv) and bivalent single chain variable fragment (bsFv) against transferrin receptor, up-stream and down-stream primers were designed according to the complementary sequences of FR1 region of variable heavy (VH) and FR4 of variable light (VL), respectively, which contained inter-linker G4S and the restriction endonuclease SfiI, AscI and NotI. Two pieces of scFv fragments were first amplified through PCR and then inserted into plasmid pAB1, which could express scFv protein once induced by IPTG in the host bacteria. To express scFv and bsFv, E. coli TG1 was cultured in LB broth and was induced by IPTG. The restriction enzyme digestion map and DNA sequencing demonstrated that scFv and bsFv genes were successfully inserted into the expression plasmid. SDS-PAGE and Western blotting revealed the protein band at 35kD and 60kD, which were consistent with the molecular weight of scFv and bsFv respectively. Flow cytometry showed that scFv and bsFv harbored the specific binding activity with TfR expressed in various tumor cells, and the avidity of bsFv was higher than that of the parent scFv.

Objective To establish a mouse model of kidney-yin and kidney?yang deficiency after oral administra?tion of hydrocortisone, and to explore the related evaluation factors. Methods The model was established by oral adminis?tration of hydrocortisone to induce kidney?yin and kidney?yang deficiency in mice. The survival and body weight of the mice were observed. The serum content of adrenal cortical hormone ( ACTH) , cortisol ( Cor. ) in the hypothalamic?pituitary?ad?renal (HPA) axis, and thyroid stimulating hormone (TSH), triiodothyronine (T3), thyrox (T4) in the hypothalamic?pi?tuitary?thyroid (HPT) axis, follicle?stimulating hormone (FSH), estradiol (E2), testosterone (T) in the hypothalamic?pituitary?gonadal ( HPG) axis were determined by radioimmunoassay. Results The body weight of kidney?yin and kidney?yang mice were decreased, the serum ACTH, Cor, TSH, T3, T4 contents were decreased, the serum FSH, E2, T contents were increased in the kidney?yang deficiency model mce ( P<0. 01 ) , and those parameters in the kidney?yin deficiency model mice were changed in opposite direction. Conclusions It is found that the hormone levels of ACTH, Cor, TSH, T3, T4, FSH, E2 and T in kidney deficiency mice are changed, and cortisol can be used as an important index to evaluate the model of kidney deficiency induced by glucocorticoid.

Objective To evaluate the synchrony of heart after catheter-based renal denervation by two dimensional speckle tracking imaging.Methods Each renal sympathetic nerve of 20 dogs were ablated,and the index of heart and blood pressure were detected 6 weeks later.Standard 2D images were acquired in the 2-,3-and 4-apical views.The times from QRS onset to peak-systolic strain rate and to peak-diastolic strain rate were measured for the longitudinal 16-segments in Qlab software,and the standard deviation were calculated.The time to peak longitudinal strain rate and time to peak contraction strain rate of left atrium were measured for each segment contained septal,latera,anterior and posterior in the level of the basal segments,middle sections and apical in Qlab software,and the standard deviation were calculated.Parameters were compared among the before and after of the ablation.Results The systolic pressure and diastolic pressure had no changes after the ablation of renal sympathetic nerve (P ＞ 0.05).The R-R showed a increasing trend,but no significant differences(P ＞0.05).The peak time of LV systolic and diastolic strain rate had a extended trendency too,but no differences(P ＞0.05),and standard deviations of the peak times had no significant differences(P ＞0.05).The peak time of LA longitudinal strain rate and contraction strain rate had a extended trendency,but no obvious change (P ＞0.05),and the standard deviations of the peak times had no significant differences (P ＞0.05).The size of the heart cavity had no differences(P ＞0.05).Conclusions The systolic pressure and diastolic pressure have no changes after the ablation of renal sympathetic nerve,and the synchrony parameters of LV and LA have no significant differences,demonstrate that the synchrony of heart is not affected by the renal sympathetic denervation.

This study was aimed to establish a quality evaluation method, quantitative analysis of multi-components with a single-marker (QAMS) to determine the contents of five saponins in Yao-Bi-Tong (YBT) capsules. Ginseno-side Rg1 was used as the internal standard; the relative correction factor (RCF) of notoginsenoside R1, ginsenoside Re, ginsenoside Rb1 and ginsenoside Rd were calculated and evaluated. The contents of 5 saponins were determined by the external standard method and QAMS, respectively. Rationality, feasibility and repeatability of the QAMS method were verified by comparing the results obtained from two different methods. The results showed that RCFs of notoginsenoside R1, ginsenoside Re and ginsenoside Rb1 to ginsenoside Rg1 against YBT capsules were 0.999, 1.228, 0.990 and 1.094, respectively, indicating good reproducibility. These results of two methods had no significant dif-ference. It was concluded that the QAMS method can be accurately, rapidly and reasonably used as a new quality assessment model for ginsenosides in YBT capsules.
