Background Measurement of ciliary sulcus distance is important for phakic intraocular lens implantation.Suowei panoramic 50-MHz digital ultrasound biomicroscopy makes it possible for the direct measurement of ciliary sulcus distance.Objective The aim of this study was to investigate the correlation between anterior chamber(AC)angle diameter and ciliary sulcus distance in different AC depth population and offer a clinical guide.Methods The anterior chamber angle diameter and ciliary sulcus distance were measured in 30 right eyes with shallow anterior chamber caused by suspect glaucoma and 30 right eyes with deep anterior chamber dut to the high myopia with Suowei panoramic 50-MHz digital ultrasound biomicroscopy.Three horizontal B-scans with the focal plane approximately at a depth corresponding to the iris plane were acquired for each eye.The differences of the anterior chamber angle diameter and ciliary sulcus distance were calculated and compared between the two groups.The correlation of the anterior chamber angle diameter and ciliary sulcus distance were evaluated in respective group.Results In shallow AC group,the mean angle diameter was(11.49+0.75)mm,the mean ciliary sulcus distance was (10.97±0.86)mm with the mean standard deviation of the difference of(-5.14± 0.55)mm,showing a statistically significant difference(t =-5.092,P =0.000).In shallow AC group,linear regression analysis showed a statistically significant correlation between ciliary sulcus distance and angle diameter(R2=0.593,P=0.000)and the Pearson's correlation coefficient was 0.767.In deep AC group,the angle diameter was(12.69±0.67)mm;while ciliary sulcus distance was(12.31 ± 0.61)mm with the mean slandard deviation(-0.38 ± 0.17)mm,which was statistically significantly different(t=-5.531,P=0.000).The ciliary sulcus distance was found to be linear correlation with the angle diameter(R2 =0.699,P=0.000)and Pearson' s correlation coefficient of 0.836.Conclusions Panoramic ultrasound biomicroscopy is an useful tool to the measurement of ciliary sulcus distance.This study exhibited that the ciliary sulcus distance is significant associated with the anterior chamber angle diameter,which may offer a guide for phakic intraocular lens implantation.

BACKGROUND:Posterior lumbar interbody fusion is a typical therapeutic method of lumbar degenerative disease. Present studies suggested that adjacent segment degeneration occurs after fusion. Recently, more and more scholars paid attention to the development of non-fusion of the spine. ＜br> OBJECTIVE:To compare clinical effects of Dynesys dynamic stabilization system fixation and posterior lumbar interbody fusion in treatment of lumbar degenerative disease. ＜br> METHODS:From July 2009 to July 2011, clinical data of 56 patients with lumbar degenerative disease were retrospectively analyzed. There were 28 cases of Dynesys dynamic stabilization system fixation, and 28 cases of posterior lumbar interbody fusion. Operation time, bleeding volume, and postoperative hospitalization time were compared in both groups. Visual analog scale was used to assess pain. Oswestry disability index was utilized to evaluate clinical effects. ＜br> RESULTS AND CONCLUSION:A total of 56 patients were fol owed up for 18-24 months. Visual analog scale and Oswestry disability index scores were significantly improved at 12 months after treatment in both groups (P＜0.01). Significant differences in operation time, bleeding volume, and postoperative hospitalization time were detected between both groups (P＜0.01). Dynesys dynamic stabilization system group was better than posterior lumbar interbody fusion group. Range of motion was better in the Dynesys dynamic stabilization system group than in the posterior lumbar interbody fusion group (P＜0.01). During fol ow-up, nail rope system and polyester sleeve loose were not detectable in the Dynesys dynamic stabilization system group. These results verified that compared with posterior lumbar interbody fusion, Dynesys dynamic stabilization system for lumbar degenerative diseases has a high safety and smal trauma, and can keep advantages of a fixed segment, and exert a certain effect on degeneration of intervertebral disc in the adjacent segment.

Objective: To observe the clinical efficacy of application in canicular days plus enteral nutrition in treating cough variant asthma (CVA) in kids, and to explore its action mechanism. Methods:Following a randomized controlled single-blind parallel-group design, 138 eligible kids with CVA were randomized into an observation group, a canicular-day application group, and an enteral nutrition group, 46 kids in each group. The canicular-day application group was intervened by application in canicular days, the enteral nutrition group was by enteral feeding, and the observation group was by both canicular-day application and enteral feeding. The therapeutic efficacies were evaluated after a treatment course. Results: The recovery rate and total effective rate were respectively 50.0% and 98.0% in the observation group, versus 23.9% and 91.3% in the canicular-day application group, and 13.0% and 78.6% in the enteral nutrition group. The observation group was significantly superior to the other two groups (bothP<0.05). In comparing the global symptom score, peak expiratory flow (PEF), forced expiratory volume in one second (FEV1), CD3+, CD4+, CD4+/CD8+, CD8+, hemoglobin (Hb), total protein (TP), albumin (ALB), eosinophil cationic protein (ECP), lipid peroxide (LPO), leukotriene (LT), body weight (BW), triceps skin-fold (TSF), and arm muscle circumference (AMC), the observation group was significantly better than the other two groups (bothP<0.05). Conclusion:Application in canicular days plus enteral nutrition can significantly improve the pulmonary function and symptoms in children’s CVA, and the effect is possibly produced by regulating cellular immune system, enhancing Hb, TP, ALB, BW, TSF, AMC, and inhibiting the production of ECP, LPO, and LT.

Objective To investigate the relationship between the expression of MAGE-1,SSX-1,and CTp11 mRNA in the peripheral blood of patients with hepatocellular carcinoma (HCC) receiving orthotopic liver transplantation (OLT) and the prognosis of these patients. [WT5”HZ]Methods The expression of the three genes in the peripheral blood mononuclear cells (PBMCs) was detected by nested RT-PCR,and a follow-up was carried out in 26 patients. Results Before OLT,the positive rate of MAGE-1,SSX-1 and CTp11 transcripts was 40.0% (14/35),37.1% (13 /34),and 31.4% (11/35),respectively in the PBMC samples of HCC patients;Sixty percent (21/35) of the PBMC samples were positive for at least one of the three gene transcripts. The follow-up of 26 patients showed that,the tumor recurrence/metastasis rate after OLT (75.0%) in 16 patients with positive preoperative PBMC samples of at least one gene transcripts was significantly higher than that of the other 10 patients who was negative preoperatively for gene transcripts (30.0%)( P = 0.043).Postoperative tumor recurrence or metastasis developed in 15 out of 20(75%) patients with persistently perioperative positive MAGE-1,SSX-1 and /or CTp11 transcripts in PBMC samples or swithing from negative to positive perioperatively,in contrast to no recurrence nor metastasis in the other 6 patients with the gene transcripts switching from positive to negative postoperatively,or negative perioperatively ( P =0.002). [WT5”HZ]Conclusions MAGE-1,SSX-1 and CTp11 transcripts may act as combined tumor-specific makers to detect tumor cells in the peripheral circulation of HCC patients,and the detection is valuable for selecting OLT candidates and predicting the postoperative prognosis.

A growing body of evidence suggests that p300 histone acetyltransferase plays important roles in cancer cell differentiation and proliferation. Here, we employed structure-based hierarchical virtual screening method to identify novel lead compounds of p300 histone acetyltransferase. From a screening library containing approximate 100 000 diverse druglike compounds, 33 compounds were chosen for experimental testing and one compound, 4-acetyl-2-methyl-N-morpholino-3,4-dihydro-2H-benzo[b][1, 4]thiazine-7-sulfonamide (17), showed as micromolar inhibitor. Based on its predicted binding pose, we investigated its binding characteristics by designing two series of structural modifications. The obtained structure-activity relationship results are consistent with the predicted binding model. We expect that the identified novel p300 histone acetyltransferase inhibitors will serve as starting points for further development of more potent and specific histone acetyltransferase inhibitors.

Objective To investigate the effect of all-trans retinoic acid (ATRA) on expression of gap junction genes 26, 32 and 43 in two human hepatocellular carcinoma cell lines. Method Human hepatocellular carcinoma cell lines SMMC-7721 and BEL-7404 were cultured and inoculated in culture plate. Cells were divided into 2 groups and cultured respectively with normal medium and medium contains ATRA at a concentration of 10-mol/L. After 24, 48 and 72 hours, cells were collected and total mRNA were extracted. RT-PCR was used to detect the transcription of gap junction genes 26, 32 and 43. Result SMMC-7721 and BEL-7404 cultured under condition of normal medium do not express CX26 mRNA and CX32 mRNA. With the effect of ATRA for 48 and 72 hours, SMMC-7721 cell expressed CX26 mRNA and CX32 mRNA. BEL-7404 expressed CX26 mRNA and CX32 mRNA while cultured with ATRA for 72 hours. CX43 mRNA expression of the two cell lines was not altered by ATRA. Conclusion ATRA affects the expression of CX26 and CX32 in HCC cell lines SMMC-7721 and BEL-7404 at the transcription level.

Objective:To identify the cerebral activation patterns associated with the processes that occur during viewing Chinese and English words in native Chinese English learners.Methods:12 right-handed Chinese English hamers were divided into two groups equally,namely English majors and non-English majors,and took semantic judgement tasks of both English and Chinese words,for whom the fMRI images were coUected.Results:To various degrees,all subjects demonstrated activation of associated cerebral regions in both hemispheres and the left hemisphere activation was more significant for most subjects.Except for elassieal regions involved in language processing,such as Wemicke areas and Broca areas,there were other activated cerebral regions,including cerebellum,limbic system and basal ganglia nucleus,etc.To sum up,there were apparent overlap for cerebral activation distribution and no specific processing areas for both tasks.The analysis of ROI(region of interest)suggested that subjects in specialized group were more dependent on right hemisphere to perform English words task.Conclus/on:Language cognition is dominated by left hemisphere,which is also shared by the right hemisphere to various degrees and thus two hemispheres work by ways of both dissociation and coordination.It is possible that working strategy of the right hemisphere in English task is related to proficiency of the second language.A variety of distinctions are shared by each subject for language cognitive patterns.
