Solid tumor growth and metastasis depends on angiogenesis.Anti-angiogenesis cancer therapy research has become one of the hot topics.Studies have shown that many kinds of Chinese medicine have an effectiveness of anti-tumor angiogenesis. It is one of the most important mechanisms to anti-tumor Chinese medicine.Chinese medicine on the anti-tumor angiogenesis research in recent years will be reviewed.

Objective The purpose of this study was to evaluate the constrast-enhanced CT features and pathologic findings of mediastinal tuberculous lymphadenitis in adults. Methods 39 patients with 180 lymph nodes diagnosed as mediastinal tuberculous lymphadenitis by operation, mediastinoscopy and biopsy were evaluated on enhanced CT scan, including 20 men and 19 women. The median age of the patients was 26 years(range from 16-67 years). Results Five post-contrast patterns of enhancement were found: (1) inhomogeneous enhancement(28.3%,51 nodes); (2) peripheral rim enhancement(26.1%, 47 nodes); (3) homogeneous enhancement(25.0%, 45 nodes); (4)nonenhancement( 14.4%, 26 nodes); (5) separate enhancement(6.11%, 11 nodes); CT-pathologic correlation demonstrated that patterns of enhancement of mediastinal tuberculous lymphadenitis were correlated with distribution of granulation tissue and caseous areas. 28 patients(71.8%) had a combination of enhancement patterns. 11 patients(28.2%) had a single enhancement pattern. Conclusion Constrast-enhanced CT appearance of mediastinal tuberculous lymphadenitis for diameter of 1.0-2.0 cm was homogeneous enhancement, nonenhancement, inhomogeneous enhancement and peripheral rim enhancement; for diameter of ≥2.0 cm was inhomogeneous enhancement, peripheral rim enhancement, homogeneous enhancement and nonenhancement. Peripheral rim enhancement or separate enhancement can suggest a diagnosis of tuberculosis.

Objective To describe varied features of pulmonary metastases of lung cancer on CT imaging .Methods 194 patients with pulmonary metastases of lung cancer were evaluated on CT scan , including 106 men and 88 women . The median age of the patients was 45 years ( range from 22 to 78 years ) . The histology of the lung cancer included 56 squamous carcinomas(28.9%),107 adenocarcinomas(55.2%),26 small cell carcinomas(13.4%),and 5 adenosquamous carcinomas(2.1%).Results The usual pattern of pulmonary metastases of lung cancer were parenchyma nodules. The unusual form of metastases that were mainly found in adenocarcinomas were cavitary lesions, ground-glass nodules and lesions with unusual signals including lobulated structure, spiculated margin,pleural indentation and air-bronchogram. The manifestations of lymphangial spread to intrapulmonary were extensive uneven thickening of the interlobular septa and fissures, nodular thickening of brochovascular bundles and many fine nodulars distributed along the brochovascular bundles and interlobular septa.Conclusion The manifestations of intrapulmonary metastases of lung cancer are varied morphologic features.

Objective To study the effects of rehabilitative training on motor function and expression of GAP-43 and SYN in rats with local cerebral infarction. Methods A total of 76 male adult Sprague-Dawley rats were randomly divided into a rehabilitative training group(n=32),a control group(n=32),and a sham-operated group(n=1 2).All the rats were subjected to left middle cerebral artery occlusion(MCAO)with the suture occlu sion.Motor training programs including balancing,grasping,rotating and walking exercises were administered to the rats of the rehabilitative training group at 48 hours post-operation,while those of other two groups were reared in their original living status without any special training.The animals were given behavioral tests with Bederson test,balancing wood test,net screen test to assess the functional outcome,and immunohistochemistry staining was employed to evaluate the exDression of GAP-43 and SYN in peri-infarction cortex at the 3rd,7th,21 st,35th days after MACO,respectively. Results The scores of behavioral tests in the rehabilitative training group was better than those in the control group(P＜0.05)at the 7th,21 st,35th day after MCAO,and the immunostaining showed that expression of GAP-43 was higher in the rehabilitative training group than that in the control group(P＜0.05)and the sham operated group(P＜0.01)at the 7th and 21 st days post-operation,respectively,and that the expression of SYN was higher in the rehabilitative training group than that in the control(P＜0.05)and the sham operated groups(P＜0.05)at the 21 st and the 35th days post-operation,respectively. Conclusion Rehabilitative training can improve func tional recovery in rats with local cerebral infarction,and the function enhancement may be partially attributed to the up-regulation of expression of GAP-43 and SYN in peri-infarction cortex.

Objective To investigate the expression of COX-2 and angiogenesis in colorectal carcinoma tissue.Methods The expressions of COX-2 and MVD of 88 cases of colorectal carcinoma and 20cases of control tissue were examined by immunohistochemical staining. Results Compared with normal control,positive expression rates of COX-2(3/20 vs 64/88),and CD34(7/20 vs 74/88)of colorectal carcinoma tissue increased significantly(P＜0.05).MVD in COX-2 positive expressed tissue(63.24-20.4)was higher than that in COX-2 negative expressed tissue(41.2±29.8)(P＜0.01).Conclusion COX-2 is overexpressed in colorectal carcinoma tissue,which may have a strong relationship with MVD.

Objective To study the effects of rehabilitation training on angiogenesis and its ultrastructure and expression of CD32 in the peri-infarction region of rats with focal cerebral infarction. Methods Sixty-six Spra-gue-Dawley rats with experimental left middle cerebral artery occlusion (MCAO) were used as subjects in this study. All the rats were randomly divided into three groups: a rehabilitation training group (n=30), which was given bar rotating, balancing and rolling exercises everyday after 48 hours post MCAO; a control group (n = 30) and a sham-operated group (n=6), which were fed in cages with no special training exercises. Then brain tissues were fixed on the 3rd d, 7th d, 14th d after MCAO, for observing the morphological alterations of microvessels in peri-infarction re-gion using transmission electron microscope, immunohistochemistry and Western blotting were used to measure the ex-pression of CD31, which acted as the marker of the neogenetic microvessels. Results (1) It showed that the capil-lary endothelial cells were less edematous in the rehabilitation training group, and there were less pinocytosis bullae in basal membrane more integral nucleus of endothelial cells in rehabilitation training group when compared with those in the control group. (2) Expression of CD31 can be observed in peri-infarction region in both groups from the 3rd d on-wards, and peaked on the 7th d, and then gradually went down after the 14th d. Comparison between the 2 groups showed that the expression of CD31 in rehabilitation training group was higher than that in the control group at every time point, but statistical difference between the 2 groups in this regard could be revealed only on the 7th d (P< 0.05), Conclusion Rehabilitation training could promote ultrastruetural recovery of microvessels and induce an-giogenesis in peri-infaretion region, and it might be one of the mechanisms of neural functional recovery in rats after MCAO.

Objective To explore the clinical value of combined detection of serum beta human chorionic gonadotropin (β-hCG),estradiol (E2),progesterone (P) and antiphospholipid antibodies (ACA) in predicting the outcomes of early threatened abortion.Methods 80 pregnant women were chosen from six to eight weeks singleton pregnancies,50 cases of threatened abortion and 30 cases of normal pregnancy.The serum levels of β-HCG,estradiol,progesterone and ACA-IgG,ACA-IgM and ACA-IgA were detected.The threatened abortion patients were given intramuscular progesterone 20 mg/day/time for 1 week,then,the pregnancy outcomes were analyzed and the serum levels of β-HCG,estradiol and progesterone were explored.Results The serum β-HCG,estradiol and progesterone of the threatened abortion group [(5 140.77 ± 2 365.47) IU/L,(680.28 ± 306.06) pg/mL,(15.59 ± 3.65) pg/L]were lower than those of the normal pregnant women [(14 520.4 ± 11 016.24) IU/L,(1 142.81 ± 670.57) pg/mL,(27.6 ± 4.78) pg/L] (t =3.224,P =0.003 ; t =2.43,P =0.022 ; t =7.72,P =0.001).According to pregnancy outcome,patients with threatened miscarriages were divided into the two groups,including 45 patients with continuing pregnancies and 5 patients with inevitable miscarriages.The serum levels of β-HCG,estradiol and progesterone in ongoing pregnancies group [(10 829.42 ± 6 926.28) IU/L,(832.9 ± 397.91) pg/mL,(25.62 ± 4.51) pg/L] were higher than those in inevitable miscarriages [(6 310.14 ± 2 593.19) IU/L,(487.14 ± 275.47) pg/mL,(13.6 ±4.84) pg/L] (P ＜ 0.05) ;The serum levels of ACA-IgG,ACA-IgM and ACA-IgA in 80 cases tested,only 2 cases who appeared in the threatened abortion group were detected with the positive of serum ACA-IgG,accounted for 4％ (2/50) (x2 =68.05,P =0.000),occurred spontaneous abortion in the end.Conclusion Combined detection of serum ACA,β-HCG,estradiol and progesterone may be helpful for prognosis of threatened abortion.However,the clinical predictive value of ACA needs further study in the early threatened abortion.
