OBJECTIVE: To investigate the effects of intermittent negative pressure therapy on the skin microcirculation perfusion of quadriceps in male rowers, and to provide basis for the practical application of this method. METHODS: Fourteen male rowers were selected from the national rowing team and randomly divided into experimental and control groups. The daily training plans of two groups were the same. The recovery intervention for experimental group was implemented by 20 minutes in the cube of Vacusport Regeneration System (German), 5 times per week for 4 weeks, no recovery intervention for control group. Microcirculation markers were collected by PeriFlux5000 system before and after the 4-week intervention. The markers included microcirculatory blood perfusion(MBP), average velocity of blood cells(AVBC), concentration of moving blood cells (CMBC), and values of the markers included basic values and post-heating values (44℃), difference before and after heating of the values was considered as the reserve capacity of those markers. RESULTS: The test results before the 4 weeks intervention showed there was no statistical difference between the two groups(P＞0.05). After the 4 weeks intervention: ①MBP: The post-heating value and the difference of the experimental group were significantly higher than those of the control group (P＜0.05). But there was no statistical inner-group difference. ②AVBC: The post-heating values and the difference in the experimental group were significantly lower than those in the control group (P＜0.05). Intra-group comparison found that the post-heating values after post-intervention were significantly reduced, compared with those of pre-intervention (P＜ 0.01); the difference after post-intervention was reduced significantly, compared with those in the pre-intervention (P＜0.05). ③CMBC: The post-heating values and the difference in the experimental group were significantly higher than those in the control group (P＜0.01). There were no statistical significant inner-group difference. CONCLUSION Lower limb intermittent negative pressure therapy can improve the skin microcirculation of the quadriceps of the male rowers, which has a positive effect on the rapid recovery of physical fitness.

OBJECTIVETo search for the morphological evidence of five-shu-point so as to explain the theory of the five-shu-point more reasonably.

METHODSCarefully study on Yellow Emperor's Internal Classic and compare with the modern anatomic knowledge.

CONCLUSIONThe theory of five-shu-point is closely related with the theory of blood vessels. The distributional pattern of the superficial vein on the remote parts of the limbs (below the elbow or the knee joints) is the morphological basis for the theory of five-shu-point.

Arteriosclerosis obliterans (ASO) of the lower extremities is a common peripheral vascular disease. Its incidence gradually increased in China in recent years. ASO may severely affect the quality of life, and even be fatal. This article summarizes the author's own experiences, along with literature review, with an attempt to discuss the therapeutic principles, indications, and strategies of the surgical therapy for ASO of the lower extremities.

OBJECTIVETo explore the possibility that the free latissimus dorsi musculo-cutaneous flap to repair the forearm leg wound.

METHODSTo design latissimus dorsi musculo-cutaneous flap which is foundation on T form thoracodorsal artery stalk. To set the short arm into the receiver artery break and anastomos them. It is not only reassure the blood of free musculo-cutaneous flap, but also reconstruct the continuation of the receiver main artery.

RESULTSIn 16 patients, 15 patients success completely, 1 patient main success. The blood supply of receiver is adequate.

CONCLUSIONSThe free T form thoracodorsal artery stalk musculo-cutaneous flap free grafting is a good method to repair the skin and soft tissues defection of forearm and leg.
