?Color vision has been an important part of the human visual function.It is determined by the phytochrome of cone.In many clinical cases of ocular fundus diseases, patients had color vision loss, which shows that color visions tests is necessary and meaningful.At present, doctors have not paid attention to it and adopt the tests rarely. The article summarizes the tests of color in common use and applications on the diagnosis and treatment for common ocular fundus diseases to be a theory basis.

Objective:To investigate the role of melatonin in calcium overload-induced heart injury.Methods:Thirty-two rats were divided into 4 groups:a control group (Control),a melatonin control group (Mel),a calcium overload group (CaP),and a calcium overload plus melatonin group (Mel+CaP).Isolated Sprague Dawley male rat hearts underwent Langendorffperfusion.Left ventricular developed pressure (LVDP) was calculated to evaluate the myocardial performance.Triphenyltetrazolium chloride staining was used to measure the infarct size of myocardium.Lactate dehydrogenase (LDH) activity in the coronary flow was determined.The expressions of caspase-3 and cytochrome c were determined by Western blot.The pathological morphological changes in myocardial fiber were analyzed by HE staining.Results:Compared with the control group,calcium overload significantly induced an enlarged infarct size (P＜0.01),accompanied by the disordered arrangement of myocardial fiber,up-regulation of cytochrome c and caspase-3 (P＜0.01),and the increased activity of LDH (P＜0.01).T hese effects were significantly attenuated by 10 μmol/L melatonin (P＜0.01).Conclusion:Melatonin can alleviate calcium overload-induced heart injury.

Ebola virus-related papers covered in PubMed and CNKI were analyzed by co-occurrence and cluster analysis, respectively. The current situation in research of Ebola virus in China and foreign countries was com-pared. Some suggestions were proposed for research of Ebola virus in China, such as attaching importance to re-search of Ebola virus, enforcing research of its vaccine,and strengthening cooperation between domestic and foreign scholars.

Objective To investigate clinieopathologic characteristics and therapy of local advanced welldifferentiated thyroid carcinoma.Methods Data of 23 cases of advanced well-differentiated thyroid carcinoma treated from Jan.1996 to Dec.2005 were retrospectively reviewed.The data included age,pathologic type,local invasion,operative plan,postoperative complications and survival duration.Results Histology showed there were 15 cases of papillary carcinoma,6 ca8es of follicular carcinoma,and 2 cases of papiIlary follicular carcinoma.8 cases had local invasion into recurrent laryngeal nerve,12 cases had invasion into trachea,3 cases had trachea and esophagus invasion,and 8 cases had suprahyoid muscle invasion.All the 23 cases underwent resection procedure.According to surgical procedure,they were divided into radical resection group(n=6),tumor resection group(n=14)and tumor debulking group(n=3).2 cases received radiotherapy after thyroidectomy in tumor debulking group.All patients were followed up.Overall survival rate after 1 year,3 years and 5 years Was 91.3%(21/23),82.6%(19/23),and 60.8%(14/23)respectively.Prognosis of radical tumor removal group and tumor resection group was obviously better than that of tumor debulking group.Conclusions Prognosis is good for local advanced well-differentiated thyroid carcinoma patients receiving resection.Protection of local organ function Can enhance postoperative life quality.

This study aimed to construct the dual-gene expression vector pHsa-miR16-siRNA which can express human miR-16 and HBV X siRNA,and examine its regulatory effect on HBV gene expression in the HepG2.2.15 cell line.The expression vectors siR-1583 and pHsa-miR16-siRNA were designed and constructed.HepG2.2.15 cells were transfected with the empty vector,siR-1583,pmiR-16 and pHsa-miR16-siRNA,respectively.ELISA was performed to measure the expression of HBsAg and HBeAg in the culture supematant 48 and72 h post transfection.Fluorescence quantitative PCR was used to measure the HBV mRNA degradation efficiency and HBV DNA copy number.The results showed that the expression of HBV genes was significantly inhibited in HepG2.2.15 cells transfected with siR-1583,pmiR-16 and pHsa-miR16-siRNA,respectively,when compared with that in cells transfected with the empty vectors,with the inhibitory effect of pHsa-miR16-siRNA being the most significant.ELISA showed that the inhibitory rates of HBsAg and HBeAg in pHsa-miR16-siRNA transfected cells were correspondingly 87.3％ and 85.0％ at 48 h,and 88.6％ and 86.5％ at 72 h post transfection (P＜0.01vs.control group).RT-PCR showed that the level of HBV mRNA decreased by 80.2％ (t=-99.22,P＜0.01),the genomic HBV DNA by 92.8％ (t=-73.06,P＜0.01),and the supernatant of HBV DNA copy number by 89.8％ (t=-47.13,P＜0.01) in pHsa-miR16-siRNA transfected group.It was suggested that the dual-gene expression vector pHsa-miR16-siRNA can inhibit the replication of HBV more efficiently than a single-gene expression vector.

OBJECTIVETo explore the effect of Jingui Shenqi pill (JGSQP) with various concentrations at different time points on pituitary adrencorticotropic hormone (ACTH) gene expression level in Shen-Yang deficiency rats.

METHODSThe Shen-Yang deficiency rats were randomly divided into the model control group and the high, medium and low dosage of JGSQP groups. Reverse transcriptase polymerase chain reaction was used to observe the effect of JGSQP on the ACTH mRNA of pituitary tissue in rats treated at different time points (10 d, 20 d, 30 d).

RESULTSAs compared with that in the model group, the ACTH gene expression level was significantly higher in the high dose JGSQP group (P < 0.05), and the increment in the medium dosage group was significantly higher in comparing with that in the high and low dosage groups (P < 0.05 or P < 0.01).

CONCLUSIONThrough up-regulation on ACTH gene expression is possibly one of the mechanisms of JGSQP in treating Shen-Yang deficiency.

Through scale-up cultivation of Eriobotrya japonica suspension cells using WAVE bioreactor, the cell growth and ursolic acid (UA) accumulation were studied. The comparison test was carried out in the flask and the reactor with cell dry weight (DW) and UA content as evaluation indexes. The culture medium, DW and UA content were compared in 1 L and 5 L working volumes of bioreactor. The orthogonal test with main actors of inoculation amount, speed and angle of rotation was developed to find the optimal combination, in 1 L working volume of bioreactor. DW of the cell growth and the UA content in bioreactor were higher than those of the shaker by 105.5% and 27.65% respectively. In bioreactor, the dynamic changes of elements in the fluid culture, the dry weight of the cell growth and the UA content in 1 L and 5 L working volumes were similar. Inoculation of 80 g, rotational speed of 26 r · min(-1), and angle of 6 ° was the optimal combination, and the cell biomass of 19.01 g · L(-1) and the UA content of 27.750 mg · g(-1) were achieved after 100 h cultivation in 1 L working volume of bioreactor. WAVE Bioreactor is more suitable than flasks for the E. japonica cell suspension culture, and culture parameters can be achieved from 1 L to 5 L amplification.
