Results: For the changes of fingernails,it was found that 80 patients(13.33%) had leukonychia punctata,2 leukonychia striata,1 total finger nails dystrophy,4 pitted nails,40(6.67%) variable numbers and degrees of longitudinal crest,transverse grooves or onycholysis.

Results showed that, pyrolin had obvious action on two species of fungi, and the antifungal effect was positively correlative with concentration. The EC50 was 0.4076 mg/mL and 0.4626 mg/mL respectively after cultured 3 days. The main antifungal period was the fast growth period of fungi, and lead to it lag behind. Observation under SEM revealed that pyrolin caused a series of marked morphological and structural alterations of hyphal. These changes included mutual adhesion of mycelium, the hyphal was irregular in diameter, local denting, some of mycelium was broken, disruption of cell wall, outbreaking of inner cytoplast, and the empty cavity appeared. As a result, pyrolin restrained the growth of these fungi.

结果表明，鹿蹄草素对上述两种真菌均具有明显的抑制作用，抑菌效果与浓度呈正相关，培养3d时的EC50分别为0.4076、0.4626 mg/mL；抑菌时期主要是在真菌的快速生长期，使其快速生长期滞后；扫描电镜显示，鹿蹄草素作用下菌体形态发生异常变化，表现为菌丝体之间相互粘连，菌丝粗细不均匀，细胞壁破裂，局部凹陷，部分菌丝断裂，大量内容物外溢，出现空腔等现象，从而发挥其抑菌作用。

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明：青南凹陷中部的下白垩统烃源岩生油门限深度为4000m（相应的镜质体反射率为0.65％），埋深4000～4400m为低成熟阶段，埋深4400～5200m为成熟生油高峰阶段，因此中沟组烃源岩未成熟，下沟组上部烃源岩低成熟，下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段，赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段，目前尚无烃源岩达过成熟干气阶段。

Results: There were scalp numbness and paraesthesia in 18 cases, incision scar in 9 cases, alopecia in 6 cases, temporal fossa introcession in 4 cases, subcutaneous hematoma in 2 cases, injury of unilateral temple branch of the facial nerve in 2 cases and naso-orbital pachynsis in 1 case.

结果：18例出现头皮麻木及感觉异常，9例有较宽切口瘢痕，6例出现脱发，4例发生颞窝凹陷，2例发生头皮下血肿，2例出现单侧面神经颞支损伤，l例发生鼻眶区肥厚。
