Background: Radiation pneumonitis is one of the most common complications during radiotherapy of thoracic tumors. It impacts the quality of life of the patients and has life-threatening danger. However, there is a lack of drugs for prevention and treatment of this disease. Objective: To evaluate the efficacy of Liangxue Jiedu Huoxue Decoction, a compound traditional Chinese herbal medicine, in prevention of radiation pneumonitis. Design, setting, participants and interventions: A prospective randomized clinical study was conducted. A total of 100 patients diagnosed with lung cancer from Department of Radiotherapy, Chinese PLA General Hospital, who were planning to receive radiotherapy, were randomly assigned into treatment group and control group, with 50 patients in each group. In the treatment group 3 cases were lost to follow-up and one case was excluded, while in the control group 6 cases were lost to follow-up and 2 cases were excluded. Patients in the treatment group were treated with Liangxue Jiedu Huoxue Decoction in addition to radiotherapy, while patients in the control group were treated with radiotherapy alone. Main outcome measures: The incidence rates of radiation pneumonitis in the two groups were calculated. Acute radiation injury scoring criteria by Radiation Therapy Oncology Group (RTOG), clinical-radiographic-physiologic (CRP) score system, and Karnofsky Performance Status Scale (KPS) were used to evaluate the status of the patients. Results: The incidence rate of radiation pneumonitis was lower in the treatment group than in the control group (13.04% versus 33.33%, P<0.05). According to the RTOG scale, the extent of lung injury was improved in the treatment group as compared with that in the control group (P<0.05). The CRP score in the treatment group was significantly lower than that in the control group (P<0.05). The KPS score in the treatment group was significantly higher than that in the control group (P<0.05). Conclusion: Liangxue Jiedu Huoxue Decoction can decrease the incidence rate of radiation pneumonitis, reduce the extent of the lung injury, alleviate the symptoms of radiation pneumonitis, and improve life quality of the patients.

Aim To investigate the inhibitory effects and mechanism of action of isoliensinine (IL) on the proliferation of porcine coronary arterial smooth muscle cells (CASMCs) induced by phenylephrine (Phen) and its mechanisms of action. Methods MTT assay, immunohistochemical method and Western blotting were adopted. Results IL (0.03-3 μmol·L-1) could inhibit the CASMCs proliferation induced by Phen (0.1 μmol·L-1) in a concentration-dependent manner. IL (0.1 μmol·L-1) antagonized Phen-induced overexpression of PDGF-β and bFGF from 0.545±0.026 and 0.47±0.03 to 0.458±0.019 and 0.376±0.017 (P<0.01, P<0.01). IL (0.1 μmol·L-1) also decreased c-fos, c-myc and hsp70 overexpression induced by Phen from 0.57±0.04, 0.44±0.04 and (173±36)% to 0.46±0.05, 0.372±0.021 and (115±35)% respectively (P<0.01, P<0.01, P<0.01). Conclusion IL exerted antiproliferative effect on CASMCs induced by phenylephrine, and its mechanisms were related to decrease the overexpression of growth factors (PDGF-β, bFGF), protooncogene (c-fos, c-myc) and hsp70.

Objective To evaluate the effect of YunKe on bone metabolism of patients with rheumatoid arthritis (RA). Methods A total of 108 RA patients were divided into YunKe group (n = 72), non-YunKe group (n = 36), and 54 controls. The bone mineral densities (BMDs) of the wrists, hips and lumbar spines were measured by dual-energy X-ray absorptiometry. Moreover , the expression of cross-linked N-telopeptides of type I collagen (NTX) in the serum was detected for statistically analyzing the difference between YunKe group and non-YunKe group. Results In RA group, the BMDs of wrist, hip and lumbar spine declined compared with that of control group (P < 0.001, respectively). In YunKe group, the BMDs of wrist, hip and lumbar spine after 6 months all were improved with statistically significance (P < 0.01, respectively); The differences also were statistically significant when compared with those in non-YunKe group (P < 0.01, respectively). In YunKe group, NTX level in the serum declined after 3 months of the treatment. The difference was statistically significant when compared with that in non-YunKe group (P < 0.001), but the difference disappeared 6 months later. Conclusions The BMD of wrist joints is low and declines in RA patients significantly. The treatment withYunKe improves the BMDs of the wrist , hip and lumbar spine and decreases the serum NTX. This study proposed that YunKe could inhibit the chronic loss of bone mass induced by RA.

We herein reported a 27-year-old woman with a right renal mass for two years. She underwent laparoscopic partial nephrectomy. Immunohistochemical examination of the specimen confirmed the diagnosis of solitary fibrous tumor by revealing its positive staining for cluster of differentiation (CD)34, epithelial membrane antigen (EMA), B-cell lymphoma-2 (Bcl-2) and CD99 in the tumor cells. No adjuvant treatment was carried out. The patient was in good health without local recurrence or metastasis during 2 years of follow-up. Laparoscopic partial nephrectomy for renal solitary fibrous tumor is an alternative treatment to radical nephrectomy. It can provide a good outcome. However, further follow-up and more cases of renal solitary fibrous tumor treated with laparoscopic partial nephrectomy are necessary to compare the oncological outcome with radical nephrectomy.

To analyze and compare the protective effects of active components in different ethyl acetate extracts (EAEEPs) from Eclipta prostrate, in order to study the comparison of materials bases protecting normal human bronchial epithelial (NHBE) cells. The MTT assay was taken to compare the protective effect of different EAEEPs on cigarette smoke extracts (CSE) -induced NHBE cells. The ultra-performance liquid chromatography (UPLC) was applied to analyze the content of phenolic acid, coumaric grass ether and flavonoid in EAEEPs. According to the results, all of the eight EAEEPs (0-200 mg x L(-1)) showed certain protective effect on NHBE cells, with statistical difference. Specifically, the total mass of EAEEP VII (89.15 mg x L(-1)) and EAEEP VIII (57.44 mg x L(-1)), which showed the strongest activity, was not the highest, while EAEEP III (132.25 mg x L(-1)) displayed the highest total mass. In the combination with the "component structure" theory, the analysis showed a significant difference in the mass structure among phenolic acid, coumaric grass ether and flavonoid in EAEEP VIII and EAEEP VIII, which were 1.0: 1. 0: 0.5 and 1.0: 1.9: 0.8, respectively. The results suggested a specific optimal "component structure" relationship may exist in EAEEP, which could provide reference for the material base study and quality control.

To explore the relationship between microecological environment and Paeonia lactiflora the effects of growth years of P. lactillora on rhizosphere bacterial communities were studied by PCR-DGGE and the paeoniflorin content determined by HPLC. Results showed that the soil pH increased with growing years of P. lactillora. In the fourth year, soil pH and enzyme activity reached the highest level, while organic matter content was the lowest. The bacterial diversity had a positive correlation with growing years varied from 3.38 to 3.61. Sequencing results demonstrated that Gammaproteobacteria, llphaproteobacteria, Actinobacteria, Acidobacte- ria and Firmicutes were predominant bacteria kinds in the soil of P. lactillora. Gammaproteobacteria was only detected in the bulk soil, while llphaproteobacteria, Acidobacteria G1l, Actinobacteria were only in the rhizosphere soil and the bacterial community among different growing years were similar except few species. HLPC results showed that paeoniflorin content was 3.26%, 3.30%, 3.36%, 3.41% separately from one to four-year-old P. lactiflora with an upward trend. The correlation analysis indicated that the paeoniflorin content had a positive correlation with soil pH and bacterial diversity, conversely, had a negative correlation with organic matter con- tent. During the growth years the rhizosphere bacterial diversity increased without changes of predominant bacteria and the paeoniflorin content increased without significant differences while its production increased significantly, which was different from the plants showing replanting diseases. This is in line with the farming practice choosing 4-year-old P. lactllora, but not the 1-3 year old one. In addition, the accumulation of paeoniflorin is closely related to soil pH, organic matter content and bacteria diversity, confirming that the geoherblism of P. lactiflora is closely related with microbial environment in the soil.
