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.

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 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 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 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.

Objective To investigate the distribution and drug resistance of pathogens of ventilator-associated pneumonia(VAP) in general intensive care unit(ICU).Methods Statistical methods were used to analyze retrospectively the data of pathogens and drug resistance of VAP in general ICU from 2004 to 2006.Results Totally 347 pathogens were isolated from deep-part secretion of lower respiratory tracts of 302 VAP in general ICU.The main pathogens included Pseudomonas aeruginosa(32.3%),Acinetobacter baumanii(31.1%),Staphylococcus aurous(16.7%),Klebsiella(7.5%) and Coagulase-negative Staphylococci(6.1%).Gram-negative bacillus showed a high resistance to piperacillin and Cefotaxime but high susceptibility to carbapenems and the enzyme inhibitor antibiotics.Gram-positive coccobacteria showed a high resistance to Penicillin,Clindamycin and Erythromycin but high susceptibility to Vancomycin and Quinolone.Conclusion Gram-negative bacillus was the main pathogen of VAP in general ICU,multidrug resistance was serious.The rate of methicillin-resistant staphylococcus aurous(MRSA) and methicillin-resistant coagulase-negative staphylococci(MRCNS) was high,with serious drug resistance.According to the data of the bacteria pathogen and antibiotics susceptibity,we can select antibiotics reasonably to control the infection and delay the emergency of new drug-resistant bacteria.

Objective To investigate the relation between VEGF and prognosis of lung carcinoma.Methods ESISA was used to investigate the level of VEGF in lung carcinoma group,pulmonary disease group and normal group,and evaluate the diagnostic efficiency of lung carcinoma transfer or dead.Results The levels of VEGF in lung carcinoma group and pulmonary disease group were significantly higher than those in normal cases(P0.05).The level of VEGF in pulmonary disease group had a degression after treatment.The negative rate of lung carcinoma was 76%.The transfer rate in the increases group of lung carcinoma was 65% in the six month.The dead rate was 10%(P

Objective To explore the value of echocardiography in patients with aortic stenosis who underwent transapical aortic valve implantation (TAAVI).Methods Fifteen high-risk patients with severe aortic stenosis were chosen in the present study,all of which received TAAVI in Fuwai Hospital Chinese Academy of Medical Sciences from June 2014 to March 2015.The left ventricular end-diastolic diameter (LVEDD),left atrial diameter (LAD),left ventricular ejection fraction (LVEF),effective orifice area (EOA),mean aortic pressure gradient (MPG),as well as artificial valve function of patients were measured at different time points (before operation,discharge,1 month and 3-6 months after operation) by echocardiography.The data were analyzed using one-way ANOVA analysis with SPSS software,and multiple comparisons were done using LSD student t test.Results The data from preoperative echocardiography indicated severe aortic stenosis in the 15 patients,with the average level of EOA as (0.55± 0.28) cm2 and MPG as (58.93± 14.96) mmHg (1 mmHg=0.133 kPa).Moderate paravalvular aortic regurgitation was observed in one patients,who was then received a second implantation.There was no significant difference between LVEDD,LAD,and LVEF when the patients were at discharge,1 month and 3-6 months after operation.The prosthetic valves were stable and conformed by echocardiography,while paravalvular leak regurgitation (1-2 mm) was observed in 7 patients.One patient died of other reasons.Compared with preoperative data,the EOA increased while MPG decreased when the patients were at discharge,1 month and 3-6 month after operation (t=6.619,7.357,6.401,all P ＜ 0.001;t=9.523,9.687,5.932,all P ＜ 0.001).Conclusion With careful patient screening and selection,TAAVI can be an effective treatment for high-risk severe aortic stenosis patients,in which echocardiography plays an important role during the surgery and follow up.
