Objective:To investigate the effects of recombinant adenovirus with human vascular endothelial growth factor 165 (Ad-hVEGF 165) and recombinant adenovirus with human tissue inhibitor of metalloproteinase 1 (Ad-hTIMP-1) on rats with myocardial infarction (MI) and its mechanism. Methods:A total of 30 healthy 8-week-old male Wistar rats were randomly divided into 5 groups: sham-operated group (sham), virus control group (Ad-Track), Ad-hVEGF 165 group, Ad-hTIMP-1 group and Ad-hVEGF 165+Ad-hTIMP-1 group (hVEGF 165+hTIMP-1) ( n=6 per group). Except the sham group, all rats were ligated the left anterior descending coronary artery to induce MI model with ST-segment elevation and Q waves or T-wave inversion on electrocardiogram and local myocardial whitening. The corresponding recombinant adenovirus comprising 100 μL (1×10 10 VP/100 μL) combined with NaCl solution was injected into the myocardial infarction area at four points respectively. The sham group received no treatment. After 4 weeks, all rats were sacrificed after echocardiography was completed and heart tissues were collected. The expression of hVEGF 165 and hTIMP-1 were detected by immunohistochemistry. The mRNA expression of apoptosis-related factors were detected by real-time PCR. The protein expression of apoptosis-related factors were detected by immunohistochemistry. Differences between groups were determined by One-way analysis of variance. Multiple comparisons between groups were performed using the least significant difference t-test. Results:(1) Both heart rate (HR) (480.83±24.09) beats/min, left ventricular end-diastolic dimension (LVEDD) (6.88±0.44) mm and left ventricular end-systolic dimension (LVESD) (4.85±0.42) mm were increased in the Ad-Track group than those in the sham group (433.16±17.86) beats/min, (6.20±0.45) mm, (4.06±0.70) mm (all P<0.05), and left ventricular ejection fraction (LVEF) (62.70±3.17) % and left ventricular fractional shortening (LVFS) (29.52±1.88) % were significantly decreased in the Ad-Track group than those in the sham group (72.78±5.44)%, (29.52±1.88) % (both P<0.01). Compared with the Ad-Track group, LVEF (71.50±6.23) % and LVFS (36.17±5.27) % in the hVEGF 165-hTIMP-1 group were significantly increased (both P<0.01), and LVEDD (6.22±0.39) mm and LVESD (4.13±0.23) mm were decreased (both P<0.05). LVEF and LVFS in the hVEGF 165-hTIMP-1 group were increased significantly than those in the Ad-hVEGF 165 group (64.65±4.00) %, (30.95±2.57) % (both P<0.05). The mRNA expression of BCL2-associated X protein (Bax), cysteine aspartate specific proteinase 3 (Caspase-3) and BCL-xL/BCL-2-associated death promoter (Bad) in the hVEGF 165-hTIMP-1 group were decreased than those in the Ad-Track group ( P<0.01 or P<0.05), and B-cell lymphoma/leukemia-2 (Bcl-2) in the hVEGF 165-hTIMP-1 group were increased than those in the Ad-Track group ( P<0.01). The mRNA expression levels of Bax and Caspase-3 in the hVEGF 165-hTIMP-1 group were decreased than those in the Ad-hVEGF 165 group (both P<0.05). There was no statistically difference in the mRNA expression of Bax, Caspase-3, Bad, and Bcl-2 between the hVEGF 165-hTIMP-1 group and the sham group (all P>0.05). The protein expression of Bax and Caspase-3 in the hVEGF 165-hTIMP-1 group were significantly decreased than those in the Ad-hVEGF 165 group, the Ad-hTIMP-1 group and the Ad-Track group (all P<0.01), and the protein expression of Bcl-2 in the hVEGF 165-hTIMP-1 group was increased than those in the Ad-hVEGF 165 group, the Ad-hTIMP-1 group and the Ad-Track group (all P<0.05). There were no statistically differences in the protein expression of Bax, Caspase-3 and Bcl-2 between the hVEGF 165-hTIMP-1 group and the sham group (all P>0.05). Conclusions:Ad-hVEGF 165 and Ad-hTIMP-1 can improve cardiac contractile function of MI rats and the beneficial effects are largely attributable to inhibiting myocyte apoptosis. The combination of hVEGF 165 and hTIMP-1 may have a synergistic effect on MI.

Objective: To observe the effects of recombinant adenovirus with human tissue inhibitor of metalloproteinase-1(Ad-hTIMP-1) on the inflammatory response in rats with myocardial infarction (MI) and explore the related mechanisms. Methods: The male Wistar rats were randomly divided into sham-operated group, saline group, Ad-Track group and Ad-hTIMP-1 group according to the random number table (n=8 each group). MI was induced by ligation of the left anterior descending coronary artery and MI rats were injected with saline, Ad-Track and Ad-hTIMP-1, respectively. Sham-operated rats received similar surgical procedure without ligation of the left anterior descending coronary artery. After 4 weeks, the cardiac function was measured by echocardiography, then rats were sacrificed and hearts were removed for morphological and biological analysis. The morphology of myocardial tissue in each group was detected by HE staining and Masson staining. The mRNA expressions of tumor necrosis factor (TNF)-α, interleukin (IL)-6, IL-10 and C-reactive protein(CRP) were detected by real-time PCR. Immune histochemical staining was performed to observe the protein expression levels of IL-6 and CRP. Results: (1) Left ventricular end systolic dimension derived from echocardiography was increased in saline group ((5.10±0.72) mm) and Ad-Track group ((4.88±0.64) mm) compared to sham-operated group ((4.25±0.46) mm), which was reduced in Ad-hTIMP-1 group ((4.13±0.35) mm, all P<0.05). The left ventricular ejection fraction was (72.46±5.74)%, (64.27±8.52)%, (64.65±3.90)%, and (71.55±6.95)%, the fractional shortening was (36.90±4.97)%, (29.03±3.40)%, (30.95±2.51)%, and (36.31±5.68)% in sham-operated group, saline group, Ad-Track group and Ad-hTIMP-1 group, respectively. The left ventricular ejection fraction and fractional shortening in saline group and Ad-Track group were lower than those in sham-operated group and Ad-hTIMP-1 group (all P<0.05). (2) Necrosis of myocardial cells was not found and a small amount of immune cell infiltration and interstitial fibrosis were observed on HE and Masson stained myocardial sections of Ad-hTIMP-1 group. (3) Real-time PCR showed that mRNA expressions of TNF-α, IL-6, IL-10 and CRP were lower in Ad-hTIMP-1 group than in saline group. mRNA expressions of TNF-α, IL-10 and CRP were lower in Ad-hTIMP-1 group than in Ad-Track group (all P<0.05). (4) Immune histochemical staining showed that protein expressions of IL-6 and CRP were higher in saline group and Ad-Track group than those in Ad-hTIMP-1 group (all P<0.05). Conclusion Recombinant adenovirus Ad-hTIMP-1 can improve cardiac function in rats with myocardial infarction via inhibiting the inflammatory response and downregulating the expression of TNF-α, IL-6 and CRP.

Objective To investigate the therapeutic effect of Ad-hVEGF165 on the endothelial cells dysfunction induced by homocysteine (Hcy) and related molecular mechanisms.Methods Human umbilical vein endothelial cells CRL-1730 were treated with Hcy at different concentrations (0,0.05,1.00 mmol/L) for 24 h.The same concentration of Hey,Ad-Track and Ad-hVEGF165 were added to the cells in the following groups:blank group,Hcy0.05 group,Hcy1.00 group,Ad-Track group,Hey0.05 + Ad-Track group,Hcy1.00 + Ad-Track group,Ad-hVEGF165 group,Hey0.05 + Ad-hVEGF165 group,Hcy1.00 + AdhVEGF165 group for 48 h.The mRNA and protein expressions of eNOS and DDAH2 were detected by realtime PCR and Western blot.The correlations of mRNA and protein expressions between endothelial nitric oxide synthase (eNOS) and dimethylarginine dimthylaminohydrolase (DDAH)2 were evaluated by Pearson correlation analysis.Results Compared with blank group and Ad-hVEGF465 group,the mRNA and protein expressions of eNOS were decreased in Hcy0.05 group and Hcy0.05 + Ad-hVEGF165 group (both P ＜ 0.05),and the mRNA and protein expressions of DDAH2 in cells treated with 0.05 mmol/L and 1.00 mmol/L Hcy were reduced as well(all P ＜ 0.05).DDAH2 mRNA and protein expression are increased (all P ＜ 0.05) in Ad-hVEGF165 group compared with the blank group and Ad-Track,Hcy0.05 + Ad-hVEGF165 and Hcy0.05 group compared with Hcy0.05 + Ad-Track group,Hcy1.00 + Ad-hVEGF165 and Hcy1.00 group compared with Hcy1.00 + Ad-Track group.The mRNA and protein expressions of eNOS and DDAH2 were uncorrelated under the effect of Hcy(r =0.057 and 0.449,both P ＞0.05) and VEGF (r =0.284 and 0.432,both P ＞ 0.05).Conclusion Recombinant adenovirus Ad-hVEGF165 could reverse Hcy-induced endothelial cells dysfunction via upregulating the expressions of eNOS and DDAH2.

Objective This paper investigated the clinical application of CRT+ARC technique in locally advanced lung cancer. Methods A total of 100 patients with locally advanced lung cancer who underwent radiotherapy in our hospital from March 1,2016 to March 1,2017 were randomly assigned to the experimental and control groups. Each group consisted of 50 patients. The CRT+ARC plans were made for the experimental group,and the CRT + intensity-modulated radiotherapy(IMRT)(CRT+IMRT) plans for the control group. According to the World Health Organization( WHO) criteria,the short-term efficacy of patients was as-sessed. According to the imaging examination and the Radiation Therapy Organization Group(RTOG)standard,the occurrence of major side effects of radiation pneumonia was identified. Results The effective rate of treatment was 82% in the experimental group and 76% in the control group. There was no difference in the effective rate between the two groups(χ2 =0. 542,P=0. 461). The incidence of pneumonia in the experimental group was 22% ,and 18% in the control group. There was also no difference in the incidence of pneumonia between the two groups(χ2 =0. 250,P=0. 617). Conclusion In the clinical application of locally advanced lung cancer, CRT+ARC technique has no difference in the short-term efficacy and the main side effects of radiation pneumonitis compared with CRT+IMRT.

Wumeiwan are recorded in the Jueyin chapter of Treatise on Cold Damage and Miscellaneous Diseases （《伤寒杂病论》）， and many doctors in the past dynasties believed that they had the effects of calming intestinal ascarid by warming Zang organs. The clinical application was limited. Since KE Qin， a doctor in the Qing dynasty， proposed that Wumeiwan were the primary prescription against Jueyin diseases， Wumeiwan have been valued by doctors， and their clinical application has also been expanded. The syndrome indicated for Wumeiwan is attributed， not only to the ascarid internal harassment， but to the abnormal Qi movement of wind and wood in Jueyin and the dysfunction of Yin and Yang. According to the functions of six meridians based on the theory of "open-close axis" in Huangdi's Internal Classic （《黄帝内经》） and the original texts of Treatise on Cold Damage and Miscellaneous Diseases， Yinshu refers to Jueyin. Wumeiwan， the primary prescription against Jueyin diseases， have the function of connecting Yin and Yang， and they can treat diseases caused by Qi disturbance of Jueyin and cold and heat in complexity. Sharing the same resource， the Secrets for Auxiliary Cultivation Life： The Essential Method of Using Herbal Medicine for the Differential Treatment of the Five Zang Organs （《辅行诀五脏用药法要》） and Treatise on Cold Damage and Miscellaneous Diseases both consult Models of the Classic of Decoction （《汤液经方》）. The formulation rules of tonic/purgative and collapse-saving prescriptions in Secrets for Auxiliary Cultivation Life follow the recorded "Tang Ye Jing Fa Tu" （an image revealing the compatibility principles of Chinese herbal drugs） and are closely related to the five elements theory. By exploring the formulation rules in "Tang Ye Jing Fa Tu" and the five elements of drugs， this study analyzed Wumeiwan and proved that Wumeiwan mainly acted on the liver， spleen， and heart. According to the Five Zang-organs Storing Spirit theory from Huangdi's Internal Classic， the above three organs are closely related to emotional adjustment. Therefore， the treatment of emotional disorders caused by qi disturbance of Jueyin and cold and heat in complexity with Wumeiwan is supported by evidence. At the end of this article， the reports on the treatment of emotional disorders with Wumeiwan in recent years were listed and reviewed. This article provides new ideas for the clinical application of Wumeiwan in the treatment of emotional disorders and expands the application range.

【Objective】 To study the therapeutic effects of tetrahydrocurcumin(THC) via intraperitoneal(i.p.) injection on the respiratory symptoms and inflammatory responses in asthmatic mice. 【Methods】 BALB/c mice were randomly divided into 4 groups, including normal control group, ovalbumin(OVA) -induced model group, positive group and THC administration group. The latter two groups were treated with 2.5 mg/kg of dexamethasone(DEX) or 20 mg/kg of THC via i.p. injection from Day 21 to Day25. The weight changes and nasal symptoms were recorded before and after OVA challenge. The mice were sacrificed at the end of the experiment and the lung tissue and broncho-alveolar lavage fluid(BALF) were collected for assessment of histopathological alterations, Th cell subsets and related cytokine level. 【Results】 After THC treatment via i.p. injection, the asthmatic mice’s rubbing frequencies were reduced(P < 0.05) with a difference of 5.2 between the two means(95% CI = 0.66 to 9.74), lungs’pathological scores were reduced(P < 0.05) with a difference between the two means being 1.6(95% CI = 0.32 to 2.88), mucus production induced by hyperplasia of goblet cells was alleviated(P < 0.0001) with a difference between the two means being 9.56(95% CI = 5.05 to 14.07). Besides, compared with OVA group, the percentages of Th2 and Th17 cells were reduced(P < 0.01) with a difference between the two means being 1.49 and 2.15(95% CI = 0.50 to 2.49 and 0.72 to 3.58), respectively. The levels of interleukin(IL) -4, IL-5, IL-13 and IL-17A in BALF were decreased(P < 0.05) with a difference between the two means being 5.45, 4.13, 5.17 and 2.44 (95% CI = 1.95 to 8.94, 1.08 to 7.19, 0.80 to 9.54 and -0.30 to 5.17), respectively. The further comparison between THC and DEX groups showed no significant difference(P > 0.05) in the lung pathological change, Th17 cells, IL-13, and IL-17A levels. 【Conclusions】 It is concluded that i.p. injection of THC could effectively alleviate the respiratory symptoms and inhibit inflammatory reaction in asthmatic mice in short time with high safety. Therefore, i.p. injection of THC has the potential value to be the alternative therapeutic strategy for asthma.
