The paper is aimed to study the difference in yield and quality at different harvest time and determine the optimum harvest of planting Gentiana in Ludian traditional harvest period. The authors analyzed the variation in fresh weight, dry weight, dry discount rate, length, diameter, volume and the content of gentiopicroside, loganin acid, alcohol-soluble extract and total ash and made a comprehensive appraisal of yield, appearance quality and intrinsic quality by gray relational distance ideal Comprehensive Evaluation method. The results showed that there is a big difference in yield and quality both 2-year-old and 3-year-old Gentiana harvested in traditional harvest period and the comprehensive evaluation more better when harvested more later. It can be seen, Gentiana harvested the later had a better yield and quality in Ludian traditional harvest period. The harvest of Gentiana can be appropriate delayed depending on the particular circumstances of production.

Objective To study the imaging of inner ear malformations in children with congenital sensorineural hearing loss(SNHL).Methods CT and MRI examinations were performed on children with SNHL diagnosed by audiological test.One hundred and eighty-eight patients with complete imaging information were obtained.The imaging of inner ear malformations was analyzed according to Sennaroglu's classification. Results Thirty-five patients(54 ears) were found with inner ear malformations by CT and MRI,3 of whom(5 ears) were accompanied by outer and middle ear malformations.Among the 35 patients,2(4 ears) were found to be common cavity deformity,1(1 ear) cochlear hypoplasia,13(26 ears) incomplete partition II(Mondini deformity),4(7 ears) vestibule dilation,13(19 ears) semicircular canal deformity and 19(34 ears) large vestibular aqueduct.Internal auditory canal was found narrow in 7 patients(10 ears) and wide in 1(2 ears) with classic Mondini deformity. Conclusion CT and MRI examinations are of great importance to the diagnosis and treatment of inner ear malformations in children with congenital SNHL,especially for the candidates of cochlear implantation.

Maspin belongs to the serine protease inhibitor (serpin) family and has been proven to be a suppressor of tumor growth and metastasis in many types of tumors. The purpose of this study was to investigate the expression of maspin in non-small cell lung cancer (NSCLC) and its relationship to vasculogenic mimicry (VM). A total of 160 specimens of NSCLC were involved in this study and 20 specimens of normal lung tissue served as controls. VM, microvessel density (MVD) and the expression of maspin were detected by using immunohistochemical staining. The results showed that the positive rates of maspin and VM in the NSCLC group were 48.1% (77/160) and 36.9% (59/160), respectively, which were significantly different from those in the control group with the positive rates of maspin and VM being 100% and 0% respectively (P<0.05). VM, MVD and the expression level of maspin were significantly related to tumor differentiation, lymph node metastasis, clinical stages and postoperative survival time (all P<0.05). The maspin expression in patients with squamous cell carcinoma was significantly higher than that in those with adenocarcinoma (P<0.05). The maspin expression was negatively correlated with VM and MVD, and there was a positive correlation between VM and MVD. Maspin-negative expression, VM and high MVD score were negatively related to the 5-year-survival rate. PTNM stages, VM, MVD and maspin expression were independent prognostic factors for NSCLC (P<0.05). It was suggested that the loss of expression of maspin may participate in the invasion and metastasis of NSCLC and it has a positive relationship to VM in NSCLC. Combined detection of maspin, VM and MVD may help predict the progression and prognosis of NSCLC.
