1. The blood supply of the tensor fascia lata myocutaneous free flap comes chiefly from the ascending branch of the lateral circumflex artery (76.74％) or its ascending and the transverse branches (23.26％). In most cases the ascending branch may be served as the vascular pedicle of myocutaneous free flap in transplatation. In a few cases the transverse branch my be used instead of the ascending one.2. The projection of the origin of the lateral circumflx artery on the body surface is at a point averaging 96.5mm below, and 49.2mm medial to the anterior superior iliac spine. This point is the surface landmark of the lateral circumflex artery. 3. The branches of the lateral circumflex artery may be classified into four types. Type 1—32 cases, 74.42％; Type Ⅱ—3 cases, 6.98％; Type Ⅲ—7 cases, 16.28％; Type Ⅳ—1 cases, 2.33％.4. The tensor fascia lata is chiefly supplied by the ascending branch of the lateral circumflex artery, it divides into a short superior and a long inferior twigs. Both twigs enter the muscle and form abundant anastomoses in the subcutaneus tissues. In order to reduce the thick ness of the free flap for the use in plastics, the superior twig with its supplying muscle is cut away and the inferior one's left to supply myocutaneus flap.5. The angle between the ascending branch and the inner surface of the tensor fasca lata varies between 44? to 120?, with an average of 66.5?. The original angle must be kept in transplantation, which favours the survival of the myocutaneus free flap.

ObjectiveTo observe the neuroprotective effect of basic fibroblast growth factor(bFGF)on cerebral diffuse axonal injuries (DAI)of rats.Methods40 male SD rats were randomly divided into control group, DAI injury group, bFGF group and DAI saline group. According to the survival time of rats, DAI injury group were divided into five groups, the 6h, 12h, 24h, 72h and 7th day group, The changes of bFGF expression in cerebral cortex were detected by immunohistochemical method from 6h to 7d after DAI. Two hours before DAI, bFGF 10μl was injected into right ventricle in bFGF group. ResultsThe bFGF expression appeared at 6h after DAI, increased at 12h, reached the highest level at 72h, and kept in a high level at 7d.There were obvious differences between 72h group and other groups in DAI injury group (P<0.01),cerebral cortex neurons were obviously decreased by HE staining. In each time group,injured neurons were decreased in bFGF group combined with DAI injury group(P<0.05). ConclusionsbFGF has obvious neuroprotective effect on cerebral diffuse axonal injuries of rats.

The present study aims to predict the action targets of antidepressant active ingredients of Xiaoyaosan to understand the "multi-components, multi-targets and multi-pathways" mechanism. Using network pharmacology, the reported antidepressant active ingredients in Xiaoyaosan (saikosaponin A, saikosaponin C, saikosaponin D, ferulic acid, Z-ligustilide, atractylenolide I, atractylenolide II, atractylenolide III, paeoniflorin, albiflorin, liquiritin, glycyrrhizic acid and pachymic acid), were used to predict the targets of main active ingredients of Xiaoyaosan according to reversed pharmacophore matching method. The prediction was made via screening of the antidepressive drug targets approved by FDA in the DrugBank database and annotating the information of targets with the aid of MAS 3.0 biological molecular function software. The Cytoscape software was used to construct the Xiaoyaosan ingredients-targets-pathways network. The network analysis indicates that the active ingredients in Xiaoyaosan involve 25 targets in the energy metabolism-immune-signal transmutation relevant biological processes. The antidepressant effect of Xiaoyaosan reflects the features of traditional Chinese medicine in multi-components, multi-targets and multi-pathways. This research provides a scientific basis for elucidation of the antidepressant pharmacological mechanism of Xiaoyaosan.

Objective To evaluate the respiration-induced dosimetric variance in 3DCRT for midthoracic esophageal carcinoma, in order to guide the radiation oncologist to choose the expansion margin. Methods Ten patients with mid-thoracic esophageal carcinoma were scanned by multi-spiral CT simulator respectively in free breathing ( FB), breath-hold after normal inspiration and expiration ( IBH and EBH )with the same scanning range. Then the CT images of three series were transferred to the treatment planning system. The target volume was outlined following the same standard. Plan1 was designed in the images of FB and transported completely to the images of IBH and EBH as Plan2 and Plan3 respectively to observe the dosimetric variance in target volume. Results For GTV, there was a statistical difference only in V100 of the three plans ( H = 6.423, P = 0.040 ) and no significant difference was found in other indexes. For CTV, the V100 and V95 were better in Plan1 (F=3.992, P=0.030; H=9.920, P=0.007) and no significant difference was found in other indexes. While ()TV, the Dmin, V100 and V95 was better in Plan1 ( F = 3.677, P = 0.039; F = 4.539, P = 0.020; H = 6.846, P = 0.033 ) and no significant difference was found in other indexes. There were no significant differences in all the indexes for the spinal cord and lung in the three plans. Conclusions The change in dose distribution was not so much with the standard expansion. It can meet the needs of clinical treatment.

Objective:To explore the effect of revision endoscopic sinus surgery (RESS) on quality of life in the patients with chronic rhinosinusitis with nasal polypsis (CRSwNP).Method:To survey and evaluate 60 cases of RESS patiens (treatment group) and 120 normal ones with physical examination (Control group) through the medical outcomes survey short form questions (MOS SF-36) and the Sino-Nasal Outcome Test-20 (SNOT-20), and comparison and analysis of the two groups results which we got were carried out.Result:With SF-36 scales for evaluation of quality of life, the results show that: the scores of CRSwNP patients (treatment group) without surgical treatments with RESS were significantly lower than that of the control group(P<0.05); while use of SNOT-20 scales in evaluation of the properative treatment group patients, the results were significantly higher than that of the control group(P<0.05). While the CRSwNP patients with surgical treatments with RESS for 6 monthes, not only with SF-36 scales but also with SNOT-20 scales,there was no significant difference between the two groups(P>0.05 ).Conclusion:RESS may obviously improve the clinical symptom of CRSNP patients. The SF-36 and SNOT-20 assessment scales could reflect the patient's QoL change.

The arterial source of the flap,the anastomoses of cutaneous arteries in theskin and subcutaneous tissue and nervous distribution in the flap were observed andsurveyed in 42 upper limbs of adult cadavers.1.The arterial source of the flap comes mainly from the cutaneous branches ofprofund brachial artery,radial collateral artery,lateral humeral cutaneous artery andcutaneous branches of the posterior circumflex humeral artery.In most cases theprofund brachial artery and radial collateral artery may be served as the vascularpedicle of the flap of lateral brachium in transplantation.2.The cutaneous arteries in this flap anastomose each other to from a networkin the skin and subcutaneous tissue.Cutaneous arteries arising from the medial brac-hial region and the upper part of forearm also participate in the formation of thisvascular network.3.The veins of the flap contain both superficial and deep groups:The superfi-cial group is the cephalic vein of brachium which goes upward along the lateralsulcus of m.biceps brachii and its outer caliber is somewhat wider;the deep groupfollows the profund brachial artery or radial collateral artery as their venae comit-antes.Both groups may be sutured together or separately with veins of the recipientin skin grafting.4.The lateral brachial cutaneous nerve and posterior antebrachial cutaneousnerve pierce through the lateral intermuscular septum at various levels,and innervateover the skin in lateral brachial and posterior forearm regions.Since the posteriorbrachial cutaneous nerve is accompanied closely by the radial collateral artery,muchattention should be paid to it in cutting skin flap.5.The extent of cutting a skin flap in lateral brachial region can be enlargeddue to free anastomoses with arteries of adjacent regions which was demonstrated byperfusing red ink into profund brachial artery.The flap of lateral brachium maybe subdivided into following three parts:the upper,middle and lower,the vascularpedicle of which are the cutaneous branch of posterior circumflex humeral artery,lateral humeral cutaneous artery and profund brachial artery(or radial collateralartery)respectively.

Objective To evaluate the impact of gross tumor volume(GTV)on prognosis of three-dimensional conformal radiotherapy(3DCRT)in esophageal carcinoma.Methods From Jan.2004 to Oct.2007,131 stageⅠ-Ⅲb patients with unreseetable esophageal carcinomas who received 3DCRT with 60 Gy/ 30f/6w were analyzed retrospectively.The effectiveness of related prognostic factors on survival was evaluated by univariate and multivariate analyses.Results The following-up rate was 100%.By univariate analysis,the 1-,2-and 3-year local tumor control rates were 71%,64%and 60%for patients with GTV volume≤40 cm3,and 43%,32%and 28%for those with GTV volume>40 cm3(X2=13.16,P=0.000).respectively.The 1-,2-and 3-year local tumor control rates were 67%,59%,59%for T1+2 patients,62%,53%,50%for T3 patients,and 41%,28%,19%for T4 patients,respectively(X2=13.25,P=0.001).The 1-,2-and 3-year survival rates were 78%,53%,46%for patients of GTV volume≤40 cm3 and 45%.27%and 7%for patients of GTV volume>40 cm3(X2=21.55,P=0.000).The 1-,2-and 3-year survival rates were 71%,50%and 39%for patients with T1+2,68%,46%and 25%with T3,and 36%,18%and 15%with T4,repectively(X2=14.35,P=0.001).The 1-,2-and 3-year survival rates for patients with tumor length≤5 cm were 75%,50%and 44%,compared with 53%,35%and 18%with tumor length>5cm(X2=5.99,P=0.014).By multivariate analysis,GTV volume and T stage were likelv to be independent prognostic factors for local tumor control rates(X2=7.07,P=0.008;X2=6.63,P=0.036).Only the GTV volume was associated with the overall survival rate(X2=15.82,P=0.000).Conclusions GTV volume is independent prognostic factor.The larger the GTV volume is,the worse the prognosis will be.

OBJECTIVE To investigate the dynamic changes in urine metabolic profiles in rats induced by D-galactose (D-Gal),and to study the correlations between the differential metabolites and behavior indicators using the proton nuclear magnetic resonance (1H-NMR)-based metabonomics.METHODS Subcutaneous injection of D-Gal 100 mg· kg-1 for 10 weeks was adopted in the model group.The sample of urine was collected at day 0 (dO),d14,d28,d42,d56 and d70.NMR metabonomics technique was used for acquisition of data,which was analyzed by multivariate statistical analysis.The ability of learning and memory were measured by Morris water maze test from d70.After the behavioral test,the rats were sacrificed and the hippocampus was observed by hematoxylin-eosin staining.RESULTS Principal component analysis (PCA) results revealed that there was considerable difference between the model group and the normal control group at d70.According to the varible importance plot (VIP) calculation and S-plot scores,a total of 12 metabolites were screened and identified as potential biomarkers at d70.The differences of metabolites and Morris water maze test were subjected to correlation analysis,and the results showed that the levels of choline,lactate and dimethylglycine in the model group were significantly increased and negatively correlated with the times of crossing the platform (r =-0.90,-0.50 and-0.52;n=10).Formate was significantly negatively correlated with the time spent in the target area (r =-0.51,n=10),but choline and formate were significantly positively correlated with the escape latency (r =0.72 and 0.53;n=10).However,the levels of creatine and taurine decreased in the model group,which was significantly positively correlated to the times of acrossing platforms (r =0.89 and 0.71;n=10),while alanine was significantly positively correlated to the time spent in the target area(r =0.74,n=10).Taurine,alanine and creatine were significantly negatively correlated with the escape latency (r =-0.66,-0.50 and-0.85;n=10).The correlations between the differential metabolites and the behavioral indicators were further proved.CONCLUSION The metabolic profile changes in urine from D-Gal induced aging model rats are significantly correlated with impairement of ability in learning and memory.1H-NMR metabonomics in urinary metabolic profile changes may be used as an evaluation index in the D-Gal induced aging rats model.

Objective To explore the relations between pulse pressure and LDL-C for elderly patients with hyperten-sion. Methods A total of 451 elderly patients with hypertension were selected and divided into four groups. Group A was 65 to 69 years of age, group B was 70 to74 years of age, group C was 75 to 79 years of age, and group D was ≥80 years of age. They were also divided into four groups according to PP levels: PP1 group ≤40 mm Hg, PP2 group 41 to 60 mm Hg, PP3 group 61 to 80 mm Hg, and PP4 group>80 mm Hg. They were divided into LDL-C group 1 (≥2.6 mmol/L) and LDL-C group 2 (<2.6 mmol/L) according to their LDL-C levels. Distribution of different age groups in four PP groups and the effects of different levels of LDL-C on pulse pressure were analyzed. Results (1) The propor-tions of PP2 group among the four age groups were 59.41%, 48.84%, 55.45% and 51.67%. The proportions of PP4 a-mong the four age groups were 4.95%, 3.88%, 3.96% and 7.50%. (2) Compared with PP1 group, the proportion of LDL-C ≥2.6 mmol/L in PP2 group, PP3 group and PP4 group was significantly increased. Conclusion (1) PP levels in different ages groups are concentrated on 41-60 mmHg. Among elderly patients with hypertension>80 mmHg, the pro-portion of patients with advanced age (≥years of age) is relatively higher. (2) LDL-C is the risk factor of increased pulse pressure for elderly patients with hypertension.
