AIM: To discuss the effect of wearing customized curvature soft corneal contact lens to dry eye degree of flight attendants.
METHODS:Eighty cases (160 eyes) of flight attendants from China Southern were divided into two groups:control group 40 cases ( 80 eyes ) wearing ready-made Bausch soft corneal contact lens ( curvature 8. 4 ); the experiment group 40 cases ( 80 eyes ) , wearing Bausch soft corneal contact lens with customized curvature. Tear break-up time ( BUT ) , Schirmer Ⅰ test ( SⅠt ) and fluorescein ( FL ) staining were as dry eye evaluation index. The results was statistically analyzed.
RESULTS: BUT, SⅠt average shortening value of the experimental group were less than that of the control group, there was statistical significance (P<0. 01). FL staining positive increase, the number of experimental group was fewer than that of control group, with statistical significance (P<0. 05).
CONCLUSION: Wearing customized curvature soft corneal contact lens can prevent the flight dry eye more effectively than fixed curvature product.

Objective To investigate the infection sites,the offending species,diagnosis and prognosis of deep fungal infections (DFI) in patients with systemic lupus erythcmatosus (SLE).Methods Fifty-one patients with fungal infections in 1466 SLE patients admitted to Peking Union Medical College (PUMC) Hospital from 2000 to 2006 were reviewed retrospectively.Results Candida albicans was ranked the first pathogen,followed by ncoformans and Aspergillus species.The infection sites were lungs,cerebral meninges and blood in the order of prevalence.The overall mortality was 20%(10/51).Aspergillasis carried the highest mortality which couht be as high as 80%.Hypoproteinemia,multiple focus of fungal infections,Aspergillasis and fungemia might he the independent risk factor for mortality.Conclusion Candida albicans is the most frequent species of fungal infections in SLE patients.Iungs are the most prevalent location of infection.Earlier diagnosis is important.Special attention should be paid to aspergillasis.

OBJECTIVE:To observe clinical efficacy and safety of Brucea javanica oil combined with gemcitabine and cisplat-in in the treatment of advanced non small cell lung cancer(NSCLC). METHODS:Totally 131 advanced NSCLC patients selected from Huanggang Hospital of TCM during Feb. 2014 to Jan. 2016 were divided into observation group(71 cases)and control group (60 cases)according to random number table. Control group was given Gemcitabine for injection(1st and 8th day)+Cisplatin injec-tion (2nd day),every 21 days,twice as a treatment course. Observation group was additionally given Breucea javanica oil oral emulsion 20 mL,po,2-3 times/d,for consecutive 14 d (3 days before chemotherapy). Both groups received treatment for 87 d and followed up until Jul. 1,2016. Clinical efficacy,the levels of T cell subsets (CD3+,CD4+,CD8+),survival time were ob-served in 2 groups. Single factor and multiple factor analysis was conducted for survival time. The occurrence of ADR was record-ed. RESULTS:The total response rate of observation group (32.39%) was higher than that of control group (25.00%),without statistical significance(P>0.05). Before treatment,there was no statistical significance in the levels of CD3+,CD4+ and CD8+ be-tween 2 groups(P>0.05). After treatment,the levels of CD3+ and CD4+ in observation group were increased significantly,while CD8+ level was decreased significantly;there was statistical significance compared to control group at corresponding period (P<0.05). Four patients withdrew from the study in observation group and 3 patients in control group. The survival time of observation group [(14.02 ± 4.10) months] was longer than control group [(13.21 ± 5.22) months],without statistical significance (P>0.05). Single factor analysis showed that the survival time of patients aged <70 were significantly longer than those of patients aged ≥70;those of patients with pleural effusion were significantly shorter than those of patients without pleural effusion;there was statis-tical significance (P<0.05). Multiple factor analysis showed that with or without pleural effusion,age were influential fac-tors for survival time of patients with advanced NSCLC(OR=1.685 and 0.647,P=0.012 and 0.043). There was no statistical significance in the incidence of ADR between observation group (50.70%) and control group (53.33%)(P>0.05). CONCLU-SIONS:Brucea javanica oil combined with gemcitabine and cisplatin in the treatment of advanced NSCLC patients,although not significantly improve the therapeutic effect,but can significantly improve the cellular immune function. With or without pleural effu-sion and age are infuential facters for survival time of advanced NSCLC patients.

The treatment and signaling pathway regulation effects of kidney- tonifying traditional Chinese medicine on osteoporosis have been widely studied, but without a systematic summary currently. This review comprehensively collected and analyzed the traditional Chinese medicine on the treatment and signaling pathway regulation of osteoporosis in recent ten years, such as Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen and Dipsacus. Based on the existing findings, we concluded the following conclusions: (1) kidney-tonifying traditional Chinese medicine treats osteoporosis mainly through BMP-Smads, Wnt/β-catenin, MAPK, PI3K/AKT signaling pathway to promote osteoblast bone formation and through OPG/RANKL/RANK, estrogen, CTSK signaling pathway to inhibit osteo?clasts of bone resorption. ① Epimedium, Drynariae Rhizoma, Cnidium and Psoralen up-regulate the key proteins and genes of BMP-Smads and Wnt/β-catenin signaling pathways to promote bone formation.② Epimedium, Drynariae Rhizoma, Cnidium, Eucommia, Psoralen, Dipsacusinhibit the bone resorption by mediating the OPG/RANKL/RANK signaling pathway. (2) Kidney-tonifying traditional Chinese medicine prevent and treat osteoporosis through a variety of ways: Icariin, Naringin, Osthol, Psoralen can regulate BMP-Smads, Wnt/β-catenin signaling pathway to promote bone formation, but also activate OPG/RANKL/RANK, CTSK and other signaling pathway to inhibit bone resorption. (3) The crosstalk of the signaling pathways and the animal experiments of the traditional Chinese medicine on the prevention and treatment of osteoporosis as well as their multi-target mechanism and comprehensive regulation need further clarification.

Diversified teaching methods including traditional teaching,problem based learning,interactive teaching and team cooperation teaching were adopted in the process of teaching.Problem based learning can stimulate students' learning interests; interactive teaching can improve the students' hands-on ability and team cooperation teaching can cultivate students' cooperation spirits.Diversified teaching mode made different teaching methods integrated and complemented each other,forming a special teaching mode for the course of functional experiment.

Objective:It intended to examine whether there is BDV infection in the human tumor tissues of central nervous system in China and investigate the correlation between BDV infection and tumom of central nervous system.Methods:Nested reverse transcriptase polymerase chain reaction(nRT-PCR)and fluorescence quantitative polymerase chain reaction(FQ-PCR)was used to detect the BDV p24 fragments in 60 samples of human tumor tissues of central nervous system and 14 normal brain tissues.Results:The study indicated the positive rate of the BDV p24 fragment in human tumor tissues of the central nervous system (6.67%)was higher than that in normal brain tissues(0),but no statistical significance(P>0.05).Concluswn:It suggests that the BDV infection is present in the human tumor tissues of central nervous system in China.while the sample size wa.sn't large enough and we could not certify the possible correlation between BDV infection and cenfral nervous system tumors.
