RESUMO
Objective:To investigate the clinical effect of free fibular flap of great toe without vein in repairing soft tissue defect of finger pulp.Methods:From June 2020 to January 2021, 8 cases of finger pulp soft tissue defect were repaired with free flap of fibular side of great toe without vein, including 6 males and 2 females, with an average age of 32(18-42) years old. The defect area of finger pulp was 1.0 cm×0.5 cm-1.8 cm×0.8 cm. The proper digital artery and digital nerve of the affected finger were anastomosed. All flaps did not carry reflux veins. The donor site of the toe was directly sutured. Postoperative routine anti infection, anti spasm and anticoagulant treatment was performed. Postoperative outpatient regular follow-up.Results:All flaps survived without vascular crisis, and the donor and recipient sites healed in the first stage. All patients were followed-up for an average of 6.4(4-12) months. At the last follow-up, the TPD was 6-8 mm, the hand function was evaluated according to the Trial Standard of Upper Limb Function Evaluation of Hand Surgery Society of Chinese Medical Association. Seven cases were excellent and 1 case was good.Conclusion:The free fibular flap of the great toe can be used to repair the small wound of finger pulp without carrying the draining vein, the flap can still survive. And it can provide a certain reference for the failure of anatomic separation of the draining vein.
RESUMO
Vertical one-and-a-half syndrome (VOHS) is a rare ophthalmoplegia syndrome caused by unilateral thalamo-mesencephalic infarct. It is manifested as a conjugate upgaze palsy and a monocular paresis of downward gaze. Recognition of VOHS helps clinical localization. No cases of VOHS with photos or videos of ocular motility have been reported in China. Herein a case of VOHS caused by unilateral thalamo-mesencephalic infarct is reported, in order to improve awareness about the ocular sign.
RESUMO
<p><b>OBJECTIVE</b>To study the morphological variations of Paris polyphylla var. yunnansensis in different population for genetic diversity and breeding.</p><p><b>METHOD</b>The characters of roots, stalks, leave and flowers were observed. The results were analyzed by DPS software.</p><p><b>RESULT AND CONCLUSION</b>P. polyphylla var. yunnansensis showed plenty genetic diversity, there existed obvious differences in morphological characters of different population. Principal components analysis showed that the number of calyces, petal, carpels, stamens is main factor,which causes the morphological variations in different population. Cluster analysis shows that 26 populations are incorporates in two types as 45.08 Euclidean distance. Leaf area index is distinct different in this two types.</p>

Objective The main economic qualities of natural triploid were evaluated and the result laid a foundation to culture new triploid variety of Dioscorea zingiberensis. Methods The ploidy level of series of D. zingiberensis from some areas of Yunnan Province were identified and the qualities of outputs per plantlet,propagation ratio,and diosgenin content etc. were measured. Results Five natural triploids were found and the qualities of the triploids all displayed diversity,output per plantlet 1 090.00—628.57 g,propagation ratio (ploidy) 72.43—29.43,dry substance ratio 36.95%—24.06%,and diosgenin content 4.40%—1.50%. The outputs of series 1 and series 3 exceed 1 000 g,the diosgenin content of series 2 reached to 4.40%,and series 3 displayed excellent quality of outputs per plantlet,propagation ratio,and diosgenin content. The synthetical index is maximum. Conclusion The series comprising good quality are obtained by the discovery of triploid and evaluation of qualities. The triploid variety is to be created with judgment and selection of progeny.
