ABSTRACT
Objective To study the evolutionary trends in the stature of Pleistocene hominins from China. Methods We took the indirect method of stature estimation from fragments of long bones; maximum length of the long bones was directly estimated from measurements of its fragments, and thereafter the stature was reconstructed from the estimated maximum length. Results The result showed that the stature variation was 155.4-169.2 cm for H. erectus (n = 4) and 155.2-171.7 cm for early modem humans (n = 12) , and only 166. 1 cm for one female in archaic Homo sapiens. The stature of Liujiang and Lijiang hominins located in the southeast was lower than other early modern humans from North China. Conclusion The stature variation is similarly from H. erectus to early modern humans, while the average stature seems to have increased continuously. We find that the geographical variation observed in modern humans has appeared in early modern humans. In addition, there is no significant difference between early modern humans and Neolithic populations.
ABSTRACT
Objective: To review the physical characteristics in modern Chinese populations, and to exploring the relationships between physical traits and the geo-environmental factors. Methods: This paper took the principal component and cluster analysis of the craniofacial physical characters of 134 populations in China (65 Han nationalities, 59 minority nationalities and 10 unidentified populations) with 15 measurements. We also focused the linear relationship between the craniofacial measurements and 8 geo-environmental factors. Results: The physical characteristics of Modern Chinese was divided into the northern and southern groups: North Han was close to north minority nationalities; Han nationalities were close to each other in southern region, as well as the minority nationalities. In addition, the physiognomic ear length and physiognomic ear breadth decreased when the annual mean temperature increases, which was not consistent with Allen's rule. Conclusion: The differentiation of northern and southern Chinese population is a result of the physical adaptation which may be caused by the selective pressures under different regional environments. And the north-south demarcation zone (Qinling mountain - Huaihe river) can be considered as the most suitable boundary between the southern and northern Chinese.
ABSTRACT
Objective To observe the effect of alteplase intra-arterial thrombolysis combined with continuous monitoring of transcranial Doppler (TCD) in patients with acute cerebral infarction. Methods Fifty-four patients with acute cerebral infarction were divided into TCD group and control group by random digits table method. The patients of 2 groups were given alteplase intra-arterial thrombolysis, and the patients of TCD groups were combined with continuous monitoring of TCD. The degree of clinical neurologic impairment was evaluated by National Institutes of Health stroke scale (NIHSS) and Barthel index (BI). The condition of vascular recanalization was evaluated by the change of blood flow signal of TCD. CT was performed within 1 d after thrombolysis to detect intracranial hemorrhage and other adverse reaction. The degree of clinical neurologic impairment, blood vessel recanalization rate after thrombolysis and recanalization time and incidence of intracranial hemorrhage and other adverse reaction were compared between 2 groups. Results There were no statistical difference in NIHSS score before thrombolysis and 1 h after thrombolysis between 2 groups (P>0.05). The NIHSS scores 7 and 30 d after thrombolysis in TCD group were significantly lower than those in control group:(8.1 ± 4.9) scores vs. (12.1 ± 4.2) scores and (6.9 ± 3.1) scores vs. (10.9 ± 3.9) scores, there were statistical differences (P<0.05). The BI scores 7 and 30 d after thrombolysis in TCD group were significantly higher than those in control group: (78.5 ± 13.8) scores vs. (60.8 ± 12.4) scores and (82.6 ± 13.5) scores vs. (63.2 ± 12.9) scores, and there were statistical differences (P<0.05). The blood vessel recanalization rate 24 h after thrombolysis in TCD group was significantly higher than that in control group: 70.4% (19/27) vs. 44.4% (12/27), the recanalization time after thrombolysis was significantly shorter than that in control group: (36.4 ± 9.5) min vs. (58.5 ± 12.4) min, and there were statistical differences (P<0.05). No adverse reaction like intracranial hemorrhage and so on was found by CT detection within 1 d after thrombolysis in the 2 groups. Conclusions Alteplase intra-arterial thrombolysis combined with continuous monitoring of TCD in acute cerebral infarction has good curative effect, and no obvious adverse reaction.
ABSTRACT
Objective To explore a reasonable therapeutic plan for treating HIV/AIDS with traditional Chinese medicine plus western medicine. Methods Twenty-nine patients with HIV/AIDS were selected and recruited into a HIV group and a AIDS group according to the clinical diagnosis. Each group was further divided into comparison stage and treatment stage. In HIV group, observations and statistics of observation indexes were performed during the comparison stage; while TCM treatment was applied in the treatment stage. In AIDS group, HAART was applied in the comparison stage, and HAART combined with TCM therapy were used in the treatment stage. Both comparison stage and the treatment stage lasted 12 months. Results In HIV group, self control results showed that immune and virus indexes did not have significant changes, but also with no side or toxic effects, In the AIDS group, contrasting between the comparison stage and the treatment stage showed that there were significant improvement of symptoms (χ2=4.9231, 2.5000, P<0.05) , anti-toxic effects (χ2=9.333、 16.4091、10.2273, P<0.01) and immune indexed(t=3.1990,P<0.01) after treated additionally with traditional Chinese medicine. Conclusion Traditional Chinese medicine could improve the immunity function and clinical symptoms, reduce side effect of HAART medicine and stabilize CD4+ T cells of patient with HIV/AIDS.
