A retrospective study of occlusal reconstruction in patients with old jaw fractures and dentition defects.

Purpose: This study evaluated the methods and clinical effects of multidisciplinary collaborative treatment for occlusal reconstruction in patients with old jaw fractures and dentition defects.

Methods: Patients with old jaw fractures and dentition defects who underwent occlusal reconstruction at the Third Affiliated Hospital of Air Force Military Medical University from January 2018 to December 2022 were enrolled. Clinical treatment was classified into 3 phases.

A potential association between Toxoplasma gondii infection and schizophrenia in mouse models.

Schizophrenia is a serious neuropsychiatric disease of uncertain etiology, which causes human mental disorder and affects about 1% of the population. In recently years, some studies showed that some cases of schizophrenia may be associated with Toxoplasma gondii infection. In order to investigate a potential association between Toxoplasma infection and schizophrenia, we investigated the relative clinical symptom of schizophrenia such as learning and memory capability, depression and stereotypy to find some useful information by behavioral test in mouse models.

[Research progress on the molecular pathogenesis of Trichomonas vaginalis].

Trichomonas vaginalis is one of the most common human sexually transmitted pathogens that colonize the urogenital mucosa. This paper reviews those factors in the molecular pathogenesis of the parasite, including cell adhesin, interaction with fibronectin and laminin, G-proteins, pore-forming protein and proteinases.

[In vitro anti-Trichomonas vaginalis effects of a mixture of dihydroartemisinin and metronidazole].

Objective: To observe the effect of a mixture of dihydroartemisinin and metronidazole on ultrastructure of Trichomonas vaginalis trophozoites in vitro for exploring trichomonacidal mechanism of the drug mixture.

Methods: The trophozoites were cultivated with liver extract solution medium that contained 2.5 x 10(6) parasites/ml.

[Effect of dihydroartemisinin on the ultrastructure of Trichomonas vaginalis trophozoites in vitro].

Objective: To observe the effect of dihydroartemisinin (DHA) on the ultrastructure of Trichomonas vaginalis cultured in vitro.

Methods: The trophozoites of T. vaginalis were cultivated with liver extract solution medium containing 1 mg/ml dihydroartemisinin, and were then observed by scanning and transmission electron microscopes after the treatment for 2.
