1.Effect of various hormones on structure and function of lacromal gland
Chinese Journal of Experimental Ophthalmology 2012;(12):1148-1152
Normal function of lacrimal gland plays an important role in the dry eye syndrome-More and more attention had been given to the impact of hormones,especially sex hormones,on lacrimal structure and function.Sex hormone replacement therapy is also considered as a new approach to the treatment of dry eye syndrome.But other hormones,example coming from hypothalamic-pituitary axis such as prolactin,promote black hormone,adrenocorticotropic hormone and luteinizing hormone,follicle-stimulating hormone,thyroid stimulating hormone and growth hormone as well as thyroid element,insulin,glucocorticoid,glucagon coming from endocrine glands also are involve in growth,differentiation,organization and functional activities of lacrimal gland.A variety of hormones-related structure and function of lacromal gland are reviewed in this paper.

4.Recurrent implantation failure: gamete and embryo factors.
National Journal of Andrology 2014;20(6):544-547
Despite the immense achievement in the field of IVF in recent years, many patients still suffer from recurrent implantation failure. Therefore, much attention has been drawn to its etiology and treatment. Chromosomal abnormality, sperm DNA damage, zona hardening, and inappropriate culture conditions are important factors that lead to recurrent implantation failure. Results of studies suggest that preimplantation genetic screening does not improve the rate of implantation or live birth. Comparative genomic hybridization array and single nucleotide polymorphism array could offer a more comprehensive screening of chromosomes. Assisted hatching may help to solve the problem of zona hardening in some situations. Co-culture and blastocyst transfer could be conducive to the improvement of the rates of implantation and pregnancy. Cytoplasmic transfer may give a solution to ooplasmic composition anomalies.

OBJECTIVE:To establish the quality standard of Compound niubangzi buccal tablets.METHODS:Lonicerae japonica and Paeonia suffruticosa in the formulation were identified by TLC,and the content of arctiin in the tablets was determined by HPLC.RESULTS:The TLC spots were clear,well-isolated and distinctive.The linear range of arctiin was 0.586~5.274 ?g(r=0.999 9)and its average recovery was 98.94%(RSD=1.68%,n=9).CONCLUSION:The established quality standard can be used for the quality control of Compound niubangzi buccal tablets.

Objective To assess the clinical effect of anterior transposition of the inferior oblique muscle (ATTO) with and without resection in the treatment of dissociated vertical deviation (DVD). Methods Thirty-six patients ( 59 eyes ) with DVD were divided into the standard group ( 30 eyes) and the resection group (29 eyes) by random digits table undertaking ATIO with and without a 7-mm resection. The vertical deviation degree in primary position and the eyeball motility were recorded and evaluated. Results The vertical deviation degree in primary position were 0△-10△ (3.5 △± 2.7△) after 3 months operation in the standard group,while 0△-12△ (3.3△±3.6△) in the resection group. There were no significant differences between two groups (P> 0.05). In the standard group, 2 cases revealed +2 inferior oblique muscle overaction (IOOA), 7 cases revealed +1 and 21 cases revealed 0 after 3 months operation. In the resection group, 1 case revealed +2 IOOA, 4 cases revealed +1 and 24 cases revealed 0 after 3 months operation. There were no significant differences between two groups(P> 0.05 ). The presence or absence of IOOA did not influence the result of ATIO for either group. Conclusions ATIO is an effective treatment for DVD and can be used to treat DVD in patients without IOOA. A 7-mm resection with the standard ATIO has no advantage to improve the surgery outcome.

Objective To explore the association between clinical pathological characteristics and the expressions of epidermal growth factor receptor (EGFR) and protein kinase B (AKT) in gastric carcinomas.Methods The expressions of EGFR and AKT were measured with immunohistochemical method in the cancer tissues and cancer-adjacent normal tissues from 153 cases of patients with gastric cancer.The association between clinical pathological characteristics and their expressions were analyzed.Results The expressions of AKT and EGFR in gastric cancer tissues had no relationship with gender,age,pathological type,and the degree of differentiation (P > 0.05).A positive correlation was existed between the EGFR and TNM stages (x2 =5.43,P <0.05).The AKT was positively related to the size,T stage,and TNM stage of the tumor,respectively (x2 =4.73,4.95,5.32,P <0.05 orP <0.01).The levels of AKT (x2=4.83,4.75,P <0.05) and EGFR(x2 =4.67,4.58,P <0.05) in the gastric cancer tissues with lymph node and/or distant metastasis were significantly higher than the gastric cancer tissues without metastasis,respectively.Conclusions The over-expressions of AKT and EGFR would benefit the diagnosis and stages of a gastric cancer and the determination of its metastasis.

Objective To study the vulnerability of astrocytes bearing mutant SOD1 under the oxidative stress.Methods The cytotoxicity of the serum deprived astrocytes was measured by MTT.The level of ROS was shown by fluorescence of DCF through confocal microscopy.The expression of Nrf2,HO1 and NQO1 in the different cells was detected by Western blot.Results The level of cellular toxicity was higher in the astrocytes bearing mutant SOD1 exposed to the oxidative stress than the astrocytes hearing wild type SOD1.In the astrocytes bearing mutant SOD1,the expression of Nrf2,HO1 and NQO1 decreased.In the presence of mutant SOD1,an unexpected 44 per-cent decrease of Nrf2 was detected.This was associated with a decreases in multiple downstream phase Ⅱ detoxif-ying enzymes and antioxidant enzymes,known as NQO1 and HO1.Furthermore,our results showed that the ex-pression of NQO1 increased 1.5 and 2.5-fold by EGCG at 5 and 10 μmol/L.EGCG also elevated the expression of total Nrf2.Confocal microscopy showed that EGCG caused Nrf2 translocation from the cytoplasm to the nucleus.Conclusion Decrease in Nrf2 expression is the mechanism to explain the vulnerability of astrocytes bearing mutant SOD1 and EGCG strengthened antioxidation function by upregulating the activity of Nrf2.
