Human height, a complex trait with over 80% heritability, is determined by genetic and environment factors. Currently, a certain amount of specific variants about human height have been found, especially with the widely used of genome-wide association studies (GWAS) in genetics research, making it a great progress for the discovering of height associated genes. However, single nucleotide polymorphisms (SNPs) found by GWAS can only explain a minority of the heritable. This article reviews the progress of GWAS about height associated genes and missing heritability domestic and overseas.

Objective:To determine the function of miR-30b in the metastasis of colorectal cancer cells. Methods:RT-qPCR was performed to test miR-30b expression in 20 fresh primary colorectal cancer tissues and their corresponding adjacent tissues. Transwell and wound healing assays were performed to test the invasion and migration of colorectal cancer cells after miR-30b overexpression or inhibition. Bioinformatics assay was performed to predict miR-30b targets. Western Blot and Dual Luciferase reporter assay were per-formed to test the expressions of Snail and downstream target genes in colorectal cancer cells. Results:The results reveal that miR-30b expression decreased in cancer tissues compared with normal tissues. Transwell and wound healing assays reveal that miR-30b overex-pression inhibited cell invasion and migration, whereas miR-30b inhibition promoted the invasion and migration of colorectal cancer cells. Bioinformatics analyses reveal that miR-30b targets the 3'-UTR of Snail. Dual Luciferase reporter assay confirms that miR-30b af-fects the 3'-UTR of Snail. Western Blot analyses show that Snail and Vimentin expressions were significantly downregulated, whereas E-cadherin expression obviously increased after miR-30b overexpression. However, Snail and Vimentin expressions increased, but E-cadherin expression decreased after miR-30b inhibition. Conclusion:The miR-30b gene is downregulated in colorectal cancer tis-sues. The miR-30b protein may be important in the regulation of cell invasion and migration by targeting Snail in colorectal cancer cells.

Objective To explore the common bleeding location, disease features, and the management strategies of intractable aged epistaxis. Methods 134 serious epistaxis patients were examined step by step according to nasal anatomic structure and treated by a stepwise way under endoscopy. Results The bleeding location of the intractable aged epistaxis were found as follows:2 cases (1. 49%) in anterosu-perior area, 44 cases (32. 84%) in anteroinferior area, 18 cases (13. 43%) in posterosuperior area, 22 cases (16. 42%) in posteroinferi-or area, 3 cases (2. 24%) in nasopharynx, and the bleeding site of the other 45 cases (33. 58%) were not found. All the patients were healed. The final treatment way were:46 cases (34. 33%) with pharmacotherapy or cauterization (grade Ⅰ~Ⅲ), 88 cases (65. 67%) with anterior nasal packing (grade Ⅳ), 9 cases (6. 72%) with posterior packing(gradeⅤ),1 case (0. 75%) with selective angiographic embolization (grade Ⅵ). There were 82 cases (61. 19%) succeed with the initial hemostasis methods while 52 cases (38. 81%) succeed with the upgrade therapy. Both hemostasis methods and upgrade therapy had statistical significance in different nasal position groups ( hemo-stasis methods:χ2 =16. 35,P=0. 00; upgrade therapy: χ2 =16. 35,P=0. 00). Conclusion Compartmental examination and classified treatment steps by using endoscope may locate and stop nose bleeding promptly while decrease patients' pain and medical cost.

Objective To explore the effect of nurse-social worker-college student volunteer team guide on care-giving competence of the primary caregivers for the long-term bedridden elderly. Methods The research was conveniently focused on a total of 60 long-term bedridden elderly and 30 primary caregivers, pension caregiver in welfare home from March to May 2015. The nurse-social worker-college student volunteer team guide for the primary caregivers included distributing health manual, training skill, psychological support, respite care and so on. The intervention lasted for 3 months, twice a month, 150 minutes each time. This was a self comparison study. The care competence for the primary caregivers and self-care ability of daily activities for the long-term bedridden elderly were conducted before and after intervention. Results Before intervention, the total score of care-giving competence was 59.07 ± 13.42. After intervention, the total score was 66.64 ± 14.16. Before intervention, the scores of caring knowledge, operation technique, behavior and attitudes, decision-making and self-efficacy were as follows:18.48±3.46, 17.95±3.98, 12.16±3.08, 7.98±2.56. Whereas, after intervention, the scores were as follows:20.32±3.58, 20.48±2.74, 14.29±3.03, 9.65±2.07. Each dimension score after intervention was significantly higher than that before intervention (t=-2.87--2.02, P<0.01). For bathing, dressing, indoor transferring and eating in self-care ability of daily activities, the numbers of people in 60 long-term bedridden elderly were 8, 13, 21, 18 before intervention and 17, 24, 43, 29 after intervention. The self-care ability of daily activities of the primary caregivers such as bathing, dressing, indoor transferring and eating after intervention were significantly higher than that before intervention (χ2=4.093-4.857, P<0.05). Conclusions Nurse-social worker-college student volunteer team guide can enhance the care-giving competence of the primary caregivers as well as improve the self-care ability of daily activities for the long-term bedridden elderly.

Objective:To develop a biotin-streptavidin system (BAS)-mediated folate receptor (FR)-targeted quantum dot (QD) fluorescent probe and preliminarily validate the targeting ability and signal amplification effect of the probe. Methods: Streptavidin (SA) was covalently coupled with QD through the active ester method;the physical characteristics of the prepared QD-SA were veri-fied. Biotinylated folate was synthesized through the carrier bovine serum albumin using the same method and then reacted with QD-SA to form the special probe. The probe was used to identify SKOV3 cells and FR-negative A549 cells to verify its targeting speci-ficity. QD-SA was used as the contrast. SKOV3 cells were imaged using the BAS-mediated FR-targeted QD probe with a biotinylated folate incubation time of 1 or 4 h. Various reaction times were also tested between the probe and the QD-FA that was formed without BAS mediation. Results:The BAS-mediated FR-targeted QD probe specifically recognized FR-positive SKOV3 cells. The probe ob-tained higher fluorescent intensity after 4 h than after 1 h of biotinylated folate incubation. The BAS-mediated FR-targeted QD probe al-so had a stronger fluorescent signal than the QD-FA probe. Conclusion:The proposed probe presents a great potential in the early diag-nosis of ovarian cancer because of its high specificity and sensitivity.

Objective To evaluate the outcomes of children with stage Ⅳ malignant extracranial germ cell tumors. Methods Twenty-five patients were enrolled in the retrospective analysis. Event-free survival (EFS) and overall survival (OS) rates were estimated by Kaplan-Meier method with SPSS 13.0. Results Of the 25 children, there were 13 males and 12 females. The mean age at diagnosis was 2 years old (ranged 1 to 11). Five patients receiving chemotherapy in another hospital before (n=1), or giving up treatment after confirmed diagnosis (n=1), or giving up effective treatment after received less than 2 cycles (n=3) were excluded from this analysis. Of the 20 patients, 90.0% (18/20) achieved complete remission and 5.0% (1/20) achieved partial remission after treatment. The 5-year EFS rate and 5-year OS rate were 70.0%±10.2% and 82.4%±9.2% respectively. There was no death occurred due to complications. Conclusions The effect of this treatment program is positive. The cumulative dose of the drugs is not high, compared with other schemes such as PEB, but there are more drugs involved. Whether these drugs may cause long-term adverse reactions needs further research.
