AIM: To investigate the postoperative changes of binocular visual function in patients with congenital superior oblique palsy.METHODS: Eye position and binocular visual function were examined in 28 patients with congenital superior oblique palsy pre- and post-operatively. The results were statistically analyzed.RESULTS: The normal eye position rate after operation was 89.3%. There were 9 patients who gained simultaneous perception after operation, while 13 patients gained fusion as many as that gained stereoacuity. There was statistically significant difference between postoperative and preoperative eyes (P<0.05). Near stereoacuity was improved after operation. Patients who had better visual acuity and low strabismus degrees as well as fusion had a better recovery.CONCLUSION: The operation could improve the eye position and rebuild the binocular visual function of the congenital superior oblique palsy. The recovery of binocular visual function was related to visual acuity and strabismus degrees of the patients and whether they had fusion function.

The contents of adenosine, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxybenzaldehyde, parishin and sulfur dioxide residue were compared in differently-processed Gastrodiae Rhizoma to provide the basis for a reasonable processing method of Gastrodiae Rhizoma. The analysis was performed on a Merck Purospher STAR column (4.6 mm x 250 mm, 5 μm) with a mobile phase consisting of methanol and water (containing 0.1% formic acid) under gradient elution at a flow rate of 1.0 mL x min(-1). The eluates were detected at 270 nm, and the column temperature was 35°C. The content of adenosin, gastrodin, 4-hydroxybenzyl alcohol, 4-hydroxy-benzaldehyde and parishin in processing of boiling or sulfur-fumigated were lower than that of in processing of steaming. Furthermore, the sulfur dioxide residue of sulphur-fumigated groups exceed 400 mg x kg(-1). This stable and reliable method will contribute to the quality control of different processed Gastrodiae Rhizoma.

Objective To explore the correlations of adult attachment with interpersonal conflict resolu-tions styles and differences between soldiers and employees. Methods Relationship questionnaire (RQ),experi-ence in close relationships (ECR),and Rahim handling interpersonal conflict inventory (ROCI-II) were adminis-tered to 543 employees from different enterprises in Beijing and Liaoning province and 701 soldiers. Results The results suggested the distribution of adult attachment style between soldiers and employees were significantly differ-ent. Compared with employees, there were higher dismissing hat lower secure rate in soldier sample. On handling interpersonal conflict strategy indices, such as integrating, avoiding, dominating and obliging but not compromising (t_((1120))=1.97, P<0.05), there were no significant differences between soldiers and employees. Only on in-tegrating, there were significant ditterenees among four adult attachment styles (F_((3,1009))=10.18, P<0.001).Attachment avoidance had a significantly negative correlation with integrating, obliging and compromising (r=-0.31,-0.11,-0.13 respectively), while attachment anxiety had moderate but significant correlations with a-voiding, dominating and obliging and compromising (r=0. 16,0.35, 0.35, 0.39, 0.30 respectively). Conclu-sion Adult attachment is closely related to handling interpersonal conflict strategies, and there was difference on compromising between soldiers and employees.

AIM AND METHODSThe relation between AT sclerosis (loss of neurons and proliferation of astrocytes) and long-lasting epileptic susceptibility was investigated by thionine staining, GFAP immunohistochemistry and observing the behavior of rats, after scorpion venom (SV) or normal saline (NS) administrated for three week.

RESULTSCompared with NS+ NS group, both the loss of neurons and proliferation of astrocytes were very marked in KA+ NS group (epileptic susceptible rats) (P < 0.05), but those changes were not visible in KA+ NS group (epileptic nonsusceptible rats).

CONCLUSIONSIt suggested that AT sclerosis may be one of important reasons of the long-lasting epileptic susceptibility.

Objective To investigate the efficacy and safety of Tripterygium wilfordii Hook F (TwHF) combined with renin-angiotensin system (RAS) blockers in chronic kidney disease (CKD) stages 2~3 of IgA nephropathy. Methods 109 patients were randomized into the observation group and the control group. On the basis of taking RAS blockers, patients in the observation group received TwHF, and patients in the control group received methylprednisolone. The proteinuria, renal function and adverse effect were observed during treatment. Results At 3, 6, 9 and 12 months of treatment, proteinuria in the two groups was lower than the baseline(P <0.05). During follow-ups, there was no significant difference of eGFR between the two groups and baseline (P >0.05). Besides, there was no significant difference in terms of proteinuria, eGFR and effective rate in the two groups. The occurrence rate of adverse effects was 9.8% vs 27.4% and there was significant difference in the two groups (P < 0.05). Conclusions TwHF combined with RAS blockers can decrease proteinuria, protect renal function and have less adverse effects, and it is a useful therapeutic options for CKD stages 2 ~ 3 of IgAN.

To compare the differences of the active ingredient contents and the sulfur dioxide residue in Astragali Radix before and after sulfur fumigation and provide a basis for establishing an alternative processing method. Astragali Radix, harvested at the same time in Longxi Gansu, were processed with different methods. high performance liquid chromatography (HPLC) was used to determine the contents of the active ingredients in Astragali Radix and the revised method of the pharmacopoeia of China in 2011 was applied to determine the sulfur dioxide residue. The results show that the three-fold sulfur-fumigation group has the highest level of astragaloside IV and the dried sulfur-fumigation group with 10% water has the lowest level; the content of calycosin-7-O-β-D-glucoside is the highest in naturally dried group and the lowest in the group of sulfur fumigating for 3 times; the sulfur dioxide residue of all sulfur-fumigation groups exceeds certain limit significantly and the group of sulfur fumigating for 3 times reaches the highest level.

Sulfur fumigation (SF) is a universal phenomenon in primary processing of Traditional Chinese Medicine (TCM) in modern times. In the process, fumigation, sulfur or both of them act on the TCMs. Some active components of TCMs change quantitatively or qualitatively during the processing. At the same time, the sulfur dioxide and heavy metal would remain and cause a serious influence on quality and future development of TCM. This article reviews the chemical compositions change after SF to study the change law and their influence on quality. This article provide references for SF in TCMs' processing for a better and safer quality.

Background The domestic and international researches discovered that many proteins and enzymes of the extracellular matrix (ECM) participate in the sclera remodeling by affecting the collagen typeⅠand fibronectin.Objective This study was to investigate the effect of matrixmetalloproteinase-2 (TIMP-2) on expression of collagen typeⅠand fibronectin of ECM in the posterior sclera by injecting liposomes containing tissue inhibitor of TIMP-2 gene into suprachoroidal space of the form-deprivation myopia in guinea pig.Methods Form-deprivation myopia was induced by translucent goggles in 36 clean guinea pig for 2 weeks.Then the animals were randomly assigned to TIMP-2 group,empty plasmid group,saline group and 12 for each group.Liposomes of 5μl containing TIMP-2 gene,empty plasmid and saline were suprachoroidally injected in the right eye respectively,and the left eyes without any treatment were used as self-control group.Other 12 matched guinea pigs only covered the right eyes through out the experimental duration as model control group.The guinea pigs were sacrificed and the posterior sclera tissue of the eyeballs were collected at 2,7 and 14 days after injection of drug.The expressions of collagen typeⅠmRNA and fibronectin mRNA were detected by semi-quantitative reverse transcription polymerase chain reaction (RT-PCR).This study followed the Regulation for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission.Results The expression level of collagen type Ⅰ mRNA in the posterior sclera of guinea pig was lower but that of fibronectin mRNA was higher in TIMP-2 group than self-control group,showing significant differences between them (P＜0.05).The expression level of collagen type Ⅰ mRNA in the posterior scleral tissue began to increase from the 2nd day after drug injection and was obviously elevated at the 7th day and then gradually decreased at the 14th day.However,the expression level of fibronectin mRNA in the posterior scleral tissue showed the opposite pattern.The expression levels of collagen typeⅠmRNA and fibronectin mRNA at the 7th after drug injection were significantly lower than that at the 2nd day or 14th day (P＜0.01).Conclusion Suprachoroidal injection of TIMP-2 in form-deprivation myopia could up-regulate the expression of collagen typeⅠmRNA and down-regulate the expression of fibronectin mRNA in the posterior scleral tissue.It may slow down the sclera remodeling of form-deprivation myopia in guinea pig in the early stage.
