Objective The kinetic house tree person test has many advantages compare to traditional psychometrics,but also some limits such as scoring subjectively and ambiguous.This research attempted to develop a reliable scoring system.That can distinguish college students with emotional disorder from normal college students by employing kinetic house tree person (KHTP) drawings.Methods 143 College students were invited to partake in the research KHTP drawings,the Beck Depression Inventory Ⅱ (BDI-Ⅱ),the Beck Anxiety Inventory (BAI) were administered to the subjects.Undergraduates with a BDI score of ≥ 14 or a BAI score of ≥8 were classified as the clinical group,while those with a BDI-Ⅱ and a BAI score are minimal were classified as the controis.The researcher and an expert studied and analyzed the KHTP drawings Manual,filtrate 35 indicators correlate to emotional disorder,and then researcher make standard for evaluation of every indicator.The standard for evaluation were then revised by the researcher and another rater then finalized by the expert.Results The results showed that 35 indicators correlate to emotional disorder were found,and there were significant differences in facial expressions (x2 =19.109,P＜0.01) and actions (x2 =13.341,P＜ 0.01) between clinical group and normal group.The Pearson coefficient of concordance showed that the inter-rater reliability and inner-rater reliability was consistent(r=0.932,r=0.913,P＜0.01).The t-test was employed to verify the discriminant validity between the clinical and control groups.The result showed that a significant discriminant validity was found with the scoring system developed in this research(t=14.890,P＜0.01).Conclusion The scoring system developed from this study has good inter-rater reliability,inner-rater reliability and discriminant validity.

Objective To investigate the reasonable anticoagulant therapy for patients over sixty five years old in Yunnan-Guizhou plateau after heart biological valve replacement , and study the standard of reasonable anticoagulant therapy. Methods We collected the recent cases by retrospective way . Low-intensity anticoagulation standard INR (1.5~2.5) was used on 130 patients over sixty five years old. The warfarin dose and anticoagulation INR values in different surgery operation were compared when the patients reached the stable anticoagulation status. The frequency of INR values and warfarin dosage were studied. The differences between the patients with high risk factors and the ordinary patients without the high risk factors in INR values and warfarin dosage were investigated. Results The INR values and warfarin doses showed no significant difference (P > 0.05) in different operation groups when they reached stable anticoagulation status. The INR values was 1.94 ± 0.50 and the daily warfarin dose was (2.45 ± 0.82)mg/d. No significant differences in INR values and warfarin doses were found between the high-risk group and the general group (P>0.05) in steady-state. During follow-up, both the incidence rate of thrombosis and general bleeding were 0.77%. Conclusion The precent study showed that the low-intensity anticoagulation INR values (1.5~2.5) can be the standard of reasonable anticoagulation in Yunnan-Guizhou plateau after heart biological valve replacement with satisfactory anticoagulant effect.

In the past decades, great progress has been made in cartilage regeneration. The traditional techniques for constructing tissue engineering cartilage scaffold mainly include pore agent method (or template method ) , phase separation method, gas foaming method, freeze-drying method , electrospinning method, etc. Cartilage is heterogeneous, and it is difficult for traditional scaffolds to simulate the high anisotropy of cartilage. Therefore, functional regeneration of cartilage is challenging. With the progress of three-dimensional (3D) printing technology, it is possible to prepare functional bionic scaffolds with fine structure and gradient changes through co deposition of biomaterials, cells and active biomolecules, so as to achieve functional cartilage regeneration. This article reviews 3D printing technology of cartilage tissue engineering, and the application of 3D printing technology in cartilage regeneration at different anatomical positions (articular cartilage, auricle cartilage, nasal cartilage) . In addition, the importance of preparing bionic constructs with regional structure gradient and regional composition gradient was discussed. 3D bioprinting technology, 4 D printing techniques, smart biomaterials brought hope for the construction of bionic tissues and organs.

OBJECTIVETo summarize the experience of the chemotherapy regimen cisplatin + fluorouracil + vincristine (C5V) for hepatoblastoma, and analyze the factors associated the outcome.

METHODA retrospective analysis was conducted for the outcome of hepatoblastoma. Sixty-three patients who received the regimen of C5V as the first choice of chemotherapy were reviewed, including 37 males and 26 females. The age at diagnosis ranged from 2 days after birth to 124 months, median 15 months. Four patients with stage I, 16 patients with stage II, 28 patients with stage III, 15 patients with stage IV disease were enrolled in the study. Nine patients had primary tumor resection while the remain by 54 received neoadjuvant chemotherapy. The median follow-up time was 30 months.

RESULTForty patients had delayed surgery, including 35 patients with regimen C5V alone, the others were treated with regimen C5V and cisplatin + adriamycin (CITA). The mean time of neojuvant chemotherapy was (3.4 ± 1.7) cycles. The mean time of chemotherapy after surgery was (5.3 ± 2.0) cycles. In 12 cases the (24.5%) tumor recurred after surgery. The margin of resection less than 0.5 cm , vascular invasion, stage III or IV disease were all the high risks of relapse (P = 0.049,0.001,0.022, respectively). Two-year overall survival (OS) and 5-year OS of the study was 61.1% and 58.7%, respectively. The 2-year OS and 5-year OS of stage I to III were 75.0% and 75.0%, 100.0% and 100.0%, 65.8% and 61.4%. The 1-year OS and 3-year OS of stage IV was 20.0%, 13.3%, respectively. Univariate analysis showed that age at diagnosis less than 60 months, vascular invasion, thrombocythemia at diagnosis, stage III or IV, tumor resection was the prognostic factor (P = 0.019, <0.001,0.011, <0.001, respectively). Multivariate analysis showed that tumor resection and age at diagnosis less than 60 months were both the prognostic factor (P < 0.001, 0.004, respectively ).

CONCLUSIONThe regimen of C5V is useful for hepatoblastoma. Tumor resection is the key factor of treatment. Prognostic factor is composed of age, stage, and clinical sign at diagnosis.
