Background and Purpose. The vascular morphology in crowd with family history of stroke remains unclear. The present study clarified the characteristics of the intracranial vascular CoW and prevalence of intracranial aneurysms in subjects with family history of stroke. Methods. A stratified cluster, random sampling method was used for subjects with family history of stroke among rural residents in Jixian, Tianjin, China. All the subjects underwent a physical examination, head computed tomography (CT) scan, and cephalic and cervical computed tomography angiography (CTA) scan. Anatomic variations in the Circle of Willis and cerebrovascular disease in this population were analyzed. Results. In the crowd with similar living environment, stable genetic background, and family history of stroke and without obvious nerve function impairment (1) hypoplasia or absence of A1 segment was significantly different in gender (male versus female: 9.8% versus 18.8%, p=0.031), especially the right-side A1 (male versus female: 5.9% versus 16.4%, p=0.004). (2) Hypoplasia or absence of bilateral posterior communicating arteries was more common in men than women (58.2% versus 45.3%, p=0.032). Unilateral fetal posterior cerebral artery was observed more often in women than men (17.2% versus 8.5%, p=0.028). (3) The percentage of subjects with incomplete CoW did not increase significantly with age. Compared to healthy Chinese people, the crowd had a higher percentage of incomplete CoW (p<0.001). (4) No obvious correlation between risk factors and CoW was found. (5) The prevalence of aneurysm was 10.3% in the special crowd. Conclusions. The certain variations of CoW showed significant relation to gender, but not to age in people with family history of stroke. The incomplete circle may be a dangerous factor that is independent of common risk factors for stroke and tend to lead to cerebral ischemia in the crowd with family history of stroke. The prevalence of intracranial aneurysm is comparatively high in the present subjects compared to other people. [ABSTRACT FROM AUTHOR]

Objective: To confirm the anticancer effect of total annonaceous acetogenins (TAAs) abstracted from Annona squamosa Linn. on human hepatocarcinoma. Methods: The inhibitory effect of TAAs was demonstrated in H-bearing mice. The potency of TAAs was confirmed as its 50% inhibiting concentration (IC) on Bel-7402 cell under Sulfur Rhodamine B staining. Both underlying mechanisms were explored as cellular apoptosis and cell cycle under flow cytometry. Mitochondrial and recipient apoptotic pathways were differentiated as mitochondrial membrane potential under flow cytometry and caspases activities under fluorescence analysis. Results: The inhibitory rate of TAAs in mice was 50.98% at 4 mg/kg dose. The IC of TAAs on Bel-7402 was 20.06 µg/mL (15.13-26.61µg/mL). Effective mechanisms of TAAs were confirmed as both of arresting cell cycle at G phase and inducing apoptosis dose- and time-dependently. Mitochondrial and recipient pathways involved in apoptotic actions of TAAs. Conclusion: TAAs is effective for hepatocarcinoma, via inhibiting proliferation and inducing apoptosis.

The article presents the findings of an experimental work and research on the effects of L. F04, the active fraction of the herb Lycopus lucidus, on erythrocytes rheological property, conducted by Shi Hong-zhi, Li Yong-zhi et al. Lycopus lucidus has effects in resisting coagulation and thrombosis. Cell rheology detector type LG-B-190 manufactured by Shidi Scientific Instrument Co. is one of the instruments used in the study. After being injected with dextran 500, rats in the model group showed characteristics of blood stasis.
