Purpose To investigate clinicopathological features, immunohistochemical findings and differential diagnosis of papillary glioneuronal tumor ( PGNT) . Methods The clinical features, imaging, histological and immunohistochemical findings were analyzed in three cases of PGNT, along with review of the related literatures. Results Two patients were female adults, and the other was male adults. One presented with dizziness, and the other exhibited intractable seizures. Magnetic resonance imaging ( MRI) revealed a cyst-ic space-occupying mass in brain parenchyma of left temporal lobe or right parietal lobe. Microscopically, it was characterized by pseu-dopapillary structures composed of hyalinized vessels rimmed by cuboidal glial cells, oligodendrocyte-like cells and the proliferation of neuronal cells. On immunohistochemical staining, the perivascular cuboidal cells were GFAP-positive, the oligodendrocyte-like cells were Olig-2-positive, and the neuronal cells were synaptophysin-and nuclear protein-positive. Conclusion PGNT is a rare and new variant of mixed neuronal-glial neoplasm, the natural evolution of this tumor is one of low malignant potential and it has a good progno-sis. The distinctive pathologic features help to differentiate this entity from other neoplasm of the central nervous system which has pa-pillary structures.

Developments in science and technology include the use of laser as an auxiliary device in treating oral diseases. Nd:YAG laser is convenient and safe to use. Nd:YAG laser irradiation leaves no scabby area on the wound surface, causes a mild reaction postoperation, and promotes high comfort. Therefore, this treatment has attracted increasing attention in the clinical setting. This review enumerates the applications of water-cooled pulsed Nd:YAG laser in hard and soft tissues in oral medicine. Nd:YAG laser in hard tissues can be applied in cavity preparation, acid etching, root canal preparation and sterilization, and dentin desensitization therapy. Meanwhile, the applications of this laser in soft tissues include adjunctive therapy in basic periodontitis treatment, gingival aesthetic treatment, and resection. This review suggests the importance of Nd:YAG laser as an auxiliary device in the clinical diagnosis and treatment of oral diseases.

It is to observe the therapeutic action of Guizhi Fuling capsule and the combination of active ingredients on model rats with uterine leiomyoma. The hysteromyoma rats models was established in rats by loading eatrogen, to observe the effect on pathological condition of uterus, uterus wet weight, the content of estradiol and progesterone. Guizhi Fuling capsule and the combination of active ingredients remarkably decreased uterus weight, restrained the excess proliferation of the smooth muscle of uterus, decreased the estraiol and progesterone in blood serum. Guizhi Fuling capsule and the combination of active ingredients can restrain the formation of hysteromyoma in a dose-dependent manner. Perhaps the combination of active ingredients is the material foundation of antihysteromyoma.

This study was aimed to observe the effects ofTian-ShuDripping Pills (TSDP) on cerebral hemodynamics among anesthetized dogs, in order to demonstrate its clinical treatment functional correlation on angioneurotic headache. A total of 25 hybrid dogs were randomly divided into the normal saline (NS) group, TS capsule (positive control: 0.4 g·kg-1 crude medicine) group, low-dose TSDP (0.2 g·kg-1 crude medicine) group, middle-dose TSDP (0.4 g·kg-1 crude medicine) group, and high-dose TSDP (0.8 g·kg-1 crude medicine) group.Intraduodenal administration was given once under anesthesia. Changes of mean arterial blood pressure, blood flow of vertebral artery and internal carotid artery blood flow were detected and the cerebral blood flow and cerebral vascular resistance were calculated. The results showed that TSDP of low-dose, middle-dose and high-dose group can significantly reduce the cerebral vascular resistance and increase the cerebral blood flow within 180 min after medication. It was concluded that TSDP can improve the cerebral blood circulation of anesthetized dogs. Its mechanism may be through the reduction on cerebral vascular resistance and increasing of cerebral blood flow.
