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 explore the roles of TIDC(tumor infiltrating dendritic cell)and TIL-T(tumor infiltrating T lymphocyte)in tumor immunity of EBV-associated gastric carcinoma(EBVaGC)and their clinical significance.[Methods]TIDC and TIL-T in EBVaGC(n=49)and EBVnGC(EBV-negative gastric carcinoma)(n=20)were detected by immunohistochemistry method and then their subtypes and their relationships with clinical and pathological factors were analyzed.[Results]Mild infiltration was detected in 29 of 49(59.2%)EBVaGCs and 18 of 20(90%)EBVnGCs,while marked infiltration of TIDC was detected in 20 of 49(40.8%)EBVaGCs and 2 of 20(10%)EBVnGCs.And the difference between the two groups was significant (P=0.013).The number of TIL-T in EBVaGC was hisher than that in EBVnGC(P=0.017),and most of them were CTLs.The number of TIL-T was positively correlated with that of TIDC(r=0.386,n=49,P=0.006).The degree of TIL-T infiltration in EBVaGC had negative relationship with the lymph node metastasis(P＜0.001),while TIDC had no relationship with the clinical features.[Conclusion]TIDC and TIL-T may play important roles in the tumor immunity of EBVaGC;TIDC may contribute to the TIL-T recruitment in EBVaGC.

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.

AIM: To explore the effect of hypertonic sugar eyes drops with local to the oxygen therapy for severe corneal edema after cataract surgery.METHODS: Totally 68 patients (68 eyes) with severe corneal edema after phacoemulsification were selected from January 2014 to December 2015 in our hospital, who were aged 53-80(64.45±4.24), including 30 males and 38 females.According to different treatment, they were divided into treatment group (34 cases) given conventional therapy + hypertonic sugar eyes drops with local to the oxygen therapy, the control group (34 cases) given conventional treatment + hypertonic sugar eyes drops.Visual acuity and corneal situation were observed during the treatment.RESULTS: Corneal edema fade time of treatment group was 11.62+0.53d, that of control group was 15.23±0.62d, the difference between the two groups was significant (P<0.05).Preoperative best corrected visual acuity (BCVA) and corneal endothelial cell count had no significantly difference between the two groups while the corneal endothelial cell count were significantly different compared with postoperative of the two groups (P<0.05).At 7d after treatment, the BCVA and corneal endothelial cell count had significantly difference between the two groups (P<0.05), which did not have significant difference at 1mo after treatment (P>0.05).The effective rates of the two groups was significantly different (P<0.05).CONCLUSION: Hypertonic sugar eyes drops with local to the oxygen therapy is effective for severe corneal edema after cataract surgery.

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 reveal the effect of rotation cropping and bacterial manure on the growth of Chrysanthemum morifolium and screen the beneficial endophytic, the diversity of endophytic and dominant genera of different treatment groups were analyzed. Four different treatments were continuous cropping, rotation, self-made organic fertilizer and commercially available fertilizer, respectively. Endophytic bacterial diversity and dominant genera in different organs were examined using Terminal Restriction Fragment Length Polymorphism (T-RFLP). The results showed that enzyme Hae III was more appropriate than enzyme Hinfl because the number of TRFs digested by enzyme Hae III was more than that of enzyme Hinfl. In comparison of diversity, the endophytic bacterial communities' diversity index in group of cropping rotation and fertilizer was higher than that of continuous cropping which indicated that the addition of exogenous microorganism in soil could increase the diversity of plant endophyte. 18 dominant species were selected, including 3 kinds of Firmicutes, 4 kinds of Actinomycetes and 11 kinds of Proteobacteria. The results of dominant species comparison showed that the number of dominant species in continuous cropping of Ch. morifolium was significantly less than that of the rotation group. Some dominant bacteria in rotation group and fertilizer group such as Arthrobacter, Streptomyces, Streptomyces, Flavobacterium and Mycobacterium were not found in the continuous cropping of Ch. mortfolium group. Dominant species of fertilizer treatment group was similar with the rotation group, and the continuous cropping group's dominant species was more abundant. It indicates that these bacteria may be able to mitigate hindrance in continuous cropping, especially the Flavobacterium which can decompose the pathogenic fungi is worthy of further attention. Compared with leaves, there are more dominant species in roots and stems. The diversity of edophytic bacterial communities in continuous cropping of Ch. morifolium stays below than that in the rotation of Ch. morifolium, and fertilizer treatment can increase the diversity of continuous cropping so that it could mitigate hindrance in continuous cropping.

To explore the mechanism of soil microbial ecology, the differences of fungal diversities in rhizosphere of different provenances of Fritillaria thunbergii were analyzed. The diversities and compositions of rhizo-fungi of the samples were analyzed by using DGGE and 454 pyrosequencing. DGGE results showed the Shannon index of Ninbo provenance planted in Ninbo was the highest one. And its dominant fungi were Ascomycota, Deuteromycota and Zygomycota. Except the same fungi, every provenance planted in Ninbo had its own special ones. From the 454 pyrosequencing, the fungal diversity in Panan producing was the highest which was similar with DGGE result. Among the ten phylum detected in its rhizosoil, Fungi_incertae_sedis, Ascomycota, Mucoromycotina, Basidiomycota and Chytridiomycota almost amounted to 90% of the whole community. The fungal types and amounts in Panan were more than those in Ninbo indicating the differences between producing areas and the advantage of macro genome sequencing. There were 10 phyla, 29 families, 28 genus and 159 species of fungi in Panan provenance, 6 phyla, 20 families, 19 genus, 136 species in Ninbo provenance, 8 phyla, 37 families, 47 genus, 289 species in Nantong provenance and 7 phyla, 25 families, 24 genus, 102 species in the bulk soil. Some genus such as Dothidea, Capnobotryella and Conidiobolus were only existed in Nantong provenance, while Pyrenochae- ta, Glomus and Pseudonectria were only in Panan provenance, which implied these species could grew because F. thunbergii influenced the existence of fungi. Experiments of provenance and producing area of F. thunbergii showed that the fungal diversity of indigenous provenance was higher than that of exotic provenance and each provenance had unique fungal species in the rhizosphere, which indicated that the diversity and structure was shaped cooperatively by the species and soil type. These fungal species are interacted with the soil-rhizhosphere-microbe microecological system, which in turn influence the growth of F. thunbergii.
