[Objective]To explore the mechanism of bioactive tanshinones in Salviae Miltiorrhiae regulating angiogenesis and lay the foundation for the prevention and treatment of cancer, atherosclerosis, ischemic heart disease and other angiogenesis-related diseases. [Method]Based on angiogenesis mechanisms, infer to recent 10 years of articles from home and abroad, analyze and summarize the angiogenesis regulatory mechanisms of various bioactive ingredients in Danshen on endothelial cells, in vitro tumour cells and in vivo xenograft tumor. [Result] Among various bioactive ingredients of Salvia, Salvianolic acid B, Tanshinone IIA, Cryptotanshinone, Dihydrotanshinone I can promote or inhibit angiogenesis. Furthermore, Salvianolic acid B and Tanshinone IIA are considered to be the most important bioactive ingredients in Danshen and exhibit a dual angiogenic regulating activity through regulating various approaches, such as pro-angiogenic factors, MMPs, HIF-1α, the PI3K/AKT/eNOS signal pathway and so on. [Conclusion]Various bioactive ingredients of Salvia can serve as a regulator of angiogenesis, and it may provide new ideas for the prevention of angiogenesis-related diseases.

Objective To investigate the use of sodium hyaluronate and the preservation of epidural fat in the prevention of epidural scar adhesion after microendoscopic discectomy (MED). Methods A total of 300 patients receiving MED from July 2000 to October 2001 were randomly divided into 2 groups: patients in group A were given sodium hyaluronate with the preservation of epidural fat, while those in group B were on the contrary. Results The mean follow-up duration was 42 months in the group A and 44 months in the group B, respectively. The rate of excellent or good results was 98.6% in the group A (144/146), while 93.8% in the group B (135/144) ( ? 2=4.731, P =0.030). Postoperatively, the pain reappeared in 4 cases in the group A and in 6 cases in the group B, respectively, in which a re-operation was required. Re-operations found the epidural scar adhesion was grade 0 (3 cases) and grade 1 (1 case) in the group A, and grade 2 (2 cases) and grade 3 (4 cases) in the group B ( P =0.005). Conclusions Use of sodium hyaluronate with the preservation of epidural fat can improve the efficacy of MED and effectively prevent epidural scar adhesion.

ve To investigate the effects of clinical relevant concentrations of midazolam on whole-cell N-type calcium currents of sympathetic ganglion neurons trying to assess the involvement of sympathetic ganglion in circulation depression produced by midazolam. Methods 7-10 d SD rats were decapitated and bilateral superior cervical ganglions were rapidly removed and kept in 4℃, oxygen saturated incubation solution. TTX 1?mol/L and nifedipine 10 ?mol/L were added to the solution to block the Na+ and L-type calcium currents. Midazolam was also added to the solution. The final concentration of midazolam were 0.1, 0.3, 3, 10, 50, 100?mol/L.The effects of different concentration of midazolam on the whole-cell N-type calcium channel currents were assessed by patch-clamp technique. Results When the holding potential (Vh) was - 80mV and stimulating votage(Vt) was between - 30mV and 10mV midazolam inhibited the whole-cell N-type calcium currents dose-dependently ( r = 0.964, P

A general situation on research about the endothelins (ET) such as its synthesis, secretion and the mitogenic activity on vascular smooth muscle cells (VSMC), and its effect on restenosis after percutaneous coronary intervention (PCI) was reviewed by the authors.

AIM: To study the effect of IFN-? inhalation on the anti-infection ability of the lungs in the immunocompromised host. METHODS: The immunological factors in the immunocompromised rats and the immunocompromised rats administrated IFN-? via aerosol were investigated after 1, 3, 7 days when they were injected Candida albicans via tracheal The Canidda albicans count of the left lung was also determined after 7 days when injecting pathogen. RESULTS: The Canidda albicans count of the left lung in IFN-? group was significantly less than that of control group. The phagocyting and bactericidal percentages, Ia antigen expression percentages, the levels of TNF-?, IL-1? and IL-6 in the culture supernatant of the AM, the activity of IFN-? and TNF-? in BALF (except the TNF-? on 7 th day) in IFN-? group were markedly higher than those in control group. The expression of IFN-? and IL-1? pulmonary tissues in IFN-? group was higher than that in control group. The expression of TNF-? in IFN-? group was less than that in control group. The expression of IL-6 was no changes between two groups. The levels of IFN-?, IL-1? and IL-6 in the blood (except IL-1? on 3 rd day), and the killing ability of the lymphocytes in blood had no difference between two groups. CONCLUSION: Administration of IFN-? via aerosol obviously enhanced the anti-infection ability of the lungs in the immunocompromised host, but has no influence on the whole body cellular immunity.

An inclusive rehabilitation model had been established in Shenzhen in light of international concepts of rehabilitation, in which the functions of medical rehabilitation, education, employment, assistive technology, care, right protection, accessible environment and culture had been integrated. The comprehensive services had been provided through this model and the target of inclusive development had been realized.

Objective:To discuss the dosimetric contribution of the ovoid in the cervical cancer brachytherapy through the intracavity combined with interstitial(IC/IS)technique.Methods:The data on 20 patients with FIGO(2009)stageⅡ A, Ⅱ B or Ⅲ Bcervical cancer treated with radical radiotherapy in China-Japan Union Hospital of Jilin University during 2015-2017 was collected. External irradiation treatment was 45 Gy/1.8 Gy× 25 fractions. Brachytherapy was MRI-guided IC/IS brachytherapy with a prescription of 28 Gy/7 Gy× 4 fractions. All of 20 patients developed two kinds of plans, the ovoid group and the non-ovoid group. The original MRI-guided brachytherapy treatment plan was set(80 fractions)to the ovoid group. As contrast model that removed the ovoid and consisted of tandem combined with needles set to the non-ovoid group was built, and the same physicist designed the plan to make the dose of D90% for high-risk clinical target volume(HR-CTV)similar to the ovoid group. The dosimetric differences of the D90% and D98% for HR-CTV, D90% and D98% for intermediate-risk clinical target volume(IR-CTV)and D2 cm 3 for the bladder, rectum, sigmoid colon and small intestines between two groups of plans were analyze by paired t-test. Results:Compared with the ovoid group, the non-ovoid group showed no significant difference on HR-CTV D90%( P>0.05), but the HR-CTV D98%(6.99±0.60 vs. 6.78±0.76), IR-CTV D90%(4.71±0.58 vs. 4.26±0.57) and D98%(3.77±0.58 vs. 3.26±0.59) of the non-ovoid group decreased significantly( t=3.906, 9.860, 8.636, P<0.05). The sigmoid colon showed no significant difference( P>0.05), while the bladder (5.29±0.67 vs. 4.92±0.74), rectum (3.72±0.69 vs. 3.35±0.92) and small intestines (3.05±1.37 vs. 2.98±1.34) D2 cm 3of the non-ovoid group decreased significantly( t=8.758, 7.543, 8.059, P<0.05). Conclusions:Ovoid is very important for IC/IS technique in cervical cancer brachytherapy. Reasonable optimization of the dose weight ratio of the ovoid and the needle can bring better clinical benefits.

Objective To assess the reliability and validity of the Somatic Self-rating Scale(SSS). Methods The sample consisted of 589 outpatients and 64 inpatients, which all the patients completed Zung's Scales at the same time to test criterion validity of the SSS. And 24 inpatients were selected randomly to take a retest after two weeks without antidepressant treatment. Result The test-retest reliability of the SSS was 0.96 and the Cronbach' s αcoefficients was 0.89. The correlation coefficients of the four factors with the total scale score ranged from 0.76 to 0.88, the correlation coefficients of the four factors ranged from 0. 56 to 0.70. The confirmatory factor analysis showed that the fit index for GFI, NFI, NNFI, CFI, IFI were all approaching 0.9, REMEA = 0. 064,x2/df = 3.67. The factor loadings ranged from 0. 427 to 0.732. Correlations with Zung's Scales were in range of 0.74to 0. 80 while the four factors were in range of 0.55 to 0.74. Drawing the ROC curve and the area under the curve was 0.841. Conclusion The SSS has a high reliability and a good validity and can be used in general hospital.
