Objective To observe the protective effect of anthocyanin on irradiation induced bone marrow c-kit positive cell injury, and further explore its possible mechanism. Methods Mouse bone marrow c-kit positive cells were collected by cell sorting method. There were 2 groups: control group and anthocyanin group, which were sub-divided into three groups and received 0 Gy, 1 Gy and 4 Gy irradiation respectively. The control group was added 700μL cell suspension and an equal volume of serum-free hematopoietic stem/progenitor cell culture medium. The 2 × 10-5 mol/L anthocyanin was co-cultured with mouse bone marrow c-kit positive cells of anthocyanin group half an hour before irradiation exposure, then cells were cultured for 18 hours under the conventional culture conditions (37℃,5%CO2). Mouse c-kit positive cell viability was measured by bioluminescence, and which was reflected by relative light units (RLU). The ability of colony-forming units was reflected by CFU-GM. The reactive oxygen species (ROS) level and mean fluorescence intensity (MFI) ofγ-H2AX were detected by flow cytometry. Results Compared to un-irradiated control group, the cell viability and the number of CFU-GM were decreased significantly, while the ROS level and MFI ofγ-H2AX were increased in c-kit positive cells irradiated with 1 Gy and 4 Gy (P<0.05). Compared to 1 Gy and 4 Gy irradiation groups, c-kit positive cell viability and the number of CFU-GM were increased, the ROS level and MFI of γ-H2AX were decreased in anthocyanin group (P < 0.05). Conclusion Anthocyanin exhibits a promising protective effect on radiation-induced bone marrow c-kit positive cell injury, which may be related to the alleviating ROS and DNA damage in bone marrow cells.

Objective:To evaluate the accuracy and feasibility of sentinel lymph node biopsy (SLNB) marked by 99Tcm-IT-Ritux-imab and to discuss the clinical value of the method in diagnosis and treatment of cutaneous melanoma. Methods:A total of 67 patients with cutaneous malignant melanoma received 99Tcm-IT-Rituximab-tagged SLNB from March 2008 to March 2012. Lymphoscintigra-phy was conducted 30 min to 1 h after intra-dermal injection of 99Tcm-IT-Rituximab. Subsequently, the surgery of SLNB was carried out using gamma probe. The detection and positive rates of SLNB were counted. The relationship between the status and the clinical features of the sentinel lymph node (SLN) was analyzed, such as the T stage, ulceration, age, gender, and location. The influence of SLN status on overall survival (OS) and disease-free survival (DFS) was evaluated. Results:SLNs were detected in all the 67 patients by SPECT and gamma detector, with detection rate of 100%. Fifteen patients had SLN metastasis, and the positive rate was 22.4%. Chi-square indicates that SLN metastasis is associated with age, T stage, and ulceration (P<0.05). A total of 63 patients were followed up for 24-69 months, and the median follow up time was 43 months. Kaplan-Meier survival analysis shows that both OS and DFS in the SLN-negative group are better than those in the SLN-positive group (OS:93.9%vs. 57.1%, P<0.01;DFS:79.6%versus 28.6%, P<0.01). Cox-regression multiple factors analysis suggests that both SLN status and T stage are independent factors that affect the DFS of malignant melanoma. Conclusion:SLNB assisted by 99Tcm-IT-Rituximab can well reflect the state of lymph node metastasis and is es-sential for accurate staging, prognosis judging, and treatment guiding. Its operation procedure is simple with high accuracy, and the im-aging status is stable. Therefore, it is convenient and feasible as a means of SLNB.

Objective:To explore the outcome of soft tissue sarcoma (STS) on patients with soft tissue metastasis. Methods:We ana-lyzed 25 STS patients with soft tissue metastasis primarily localized on extremity and trunk. The study was conducted from June 2010 to June 2016 by retrospective analysis of the clinical and pathological characteristics of the patients. The assessed endpoints were overall survival. Results:Six patients (24%) had synchronous soft tissue metastasis, and 19 patients (76%) had metachronous metasta-sis. The average time for primary tumor recession of metastatic lesions was 45.3 months. Metastases were most common in parts of the trunk in 18 patients (72%), followed by the head and neck in 5 patients (20%). Eleven patients (44%) with lung metastasis had poor prognosis. Conclusion:STS occurred more rarely in soft tissue metastasis than in pulmonary metastasis. Neoadjuvant chemotherapy and surgical treatment were the major therapies employed. Targeted therapy as a new treatment rendered good results.

Water soluble extract (WSE) is an important index for the quality evaluation of Astragali Radix (AR). In this study, the WSE of the wild AR from Shanxi province (SX) and the cultivated AR from Gansu Province (GS) were compared. The WSEs of two types of AR were determined according to the appendix of Chinese pharmacopoeia. Then the WSEs were subjected to NMR analysis, and the obtained data were analyzed using HCA, PCA, OPLS-DA, microarray analysis, and Spearman rank analysis. In addition, the Pearson correlation of differential metabolites were also calculated. The results showed that the WSE content of GS-AR (37.80%) was higher than that of SX-AR (32.13%). The main constituent of WSE was sucrose, and other 18 compounds, including amino acids, organic acids, were also detected. Multivariate analysis revealed that SX-AR contained more choline, succinic acid, citric acid, glutamate, taurine and aspartate, while GS samples contained more sucrose, arginine and fumaric acid. In addition, the Pearson correlations between different metabolites of the two types of AR also showed apparent differences. The results suggested that the WSE of two types of AR differs not only in the content, but also in the chemical compositions. Thus, the cultivation way is important to the quality of AR. This study supplied a new method for the comparison of extract of herbal drugs.

Objective:To evaluate the safety and feasibility of the in-situ needle fenestration combined with the in vitro physician modified fenestration technique to reconstruct supra-aortic branches during thoracic endovascular aortic repair (TEVAR) for aortic arch lesions requiring landing at Z0 and Z1.Methods:From Nov 2017 to Dec 2019, eighteen patients who underwent both the in-situ needle fenestration and the in vitro physician modified fenestration techniques to extend the proximal landing zone to Z0 and Z1 during TEVAR were included in our study.Results:Sixteen patients underwent in vitro physician modified fenestration ,two patients underwent in vitro physician modified fenestration to reconstruct both the left common carotid artery and the innominate artery. All eighteen patients received in-situ needle fenestration to preserve the left subclavian artery. Supra aortic branches were preserved in all patients (38/38, 100%). There was no Type Ⅰ endoleak. Type Ⅱ endoleak was found in four paitnets (4/18). Type Ⅲ endoleak occurred in one patient (1/18). Type Ⅳ endoleak in four patients (4/18). Type Ⅲ endoleak needed open aortic arch repair 6 months later. The median follow-up time was 12 months. One (1/18) died in 12 months and the other patients were doing well.Conclusions:The joint application of the in-situ needle fenestration and the in vitro physician modified fenestration to reconstruct supra-aortic branches during TEVAR for aortic arch pathologies requiring landing at Z0 and Z1 was satisfactory.

Objective:To analyze the clinical prognostic factors of liposarcoma on the extremities and trunk, as well as to retrospectively analyze the effect of adjuvant radiotherapy and chemotherapy on liposarcoma of the extremities. Methods:Patients with liposarcoma of the extremities treated in our hospital from July 1, 2007 to December 31, 2012 were followed up. The relationship of clinical prognostic factors with gender, age, location, depth, and size of the tumors, as well as the histological grade and admission status, were statistically analyzed. The effects of adjuvant radiotherapy or chemotherapy on overall survival (OS) and disease free survival (DFS) were evaluated. Results:A total of 82 patients with extremity liposarcoma received surgery-based comprehensive treatment in our hospital. Of the total patients, 73 received a 24-month to 88-month satisfied follow-up;the median follow-up time was 47 months. The OS rate was 83.6%(61/73), and the DFS rate was 68.5%(50/73). Multivariate Cox regression analysis showed that the tumor location, histological grade, and admission status were the independent correlative factors influencing DFS, and the age and pathologic grading were the independent correlative factors influencing the OS. Kaplan-Meier survival analysis showed that radiation therapy can significantly improve the DFS and OS of the G2 and G3-grade liposarcoma (DFS:59.1 months vs. 28.4 months, P<0.01;OS:70.8 months vs. 55.1 months, P<0.05). Significant difference was not found in the effect of chemotherapy on OS and DFS. Conclusion:The prognosis of liposarcoma was significantly associated with the pathologic grades and subtypes. Auxiliary radiotherapy could improve the survival and prognosis of G2 and G3 liposarcoma of the extremities, but the role of chemotherapy in treating liposarcoma remained unclear.

OBJECTIVETo observe the clinical efficacy of acupuncture at Hegu (LI 4) on central facial nerve paralysis after ischemic stroke, and explore dose-effect relationship among different stimulation intensities of acupuncture at Hegu (LI 4) as well as its optimal treatment plan.

METHODSAccording to different acupuncture stimulation intensities which were based on treatment time and needle insertion direction, fifty patients were randomly divided into a Hegu 1 group, a Hegu 2 group, a Hegu 3 group, a Hegu 4 group and a control group, ten cases in each one. Different stimulation intensities of acupuncture at Hegu (LI 4) combined with facial paralysis acupoints, including Yingxiang (LI 20), Dicang (ST 4), Jiache (ST 6) and Quanliao (SI 18), were applied in Hegu 1 to 4 groups; meanwhile acupuncture at stroke acupoints, including Neiguan (PC 6), Shuigou (GV 26) and Sanyinjiao (SP 6), and medication treatment were adopted. Except acupuncture at Hegu (LI 4), the treatment of the control group was identical as Hegu groups. The treatment duration lasted for 14 days. The House-Brackmann facial never grading systems (H-B), Toronto facial grading system (TFGS), degrees of facial never paralysis (DFNP), facial disability index (FDI) and clinical efficacy were compared among groups.

RESULTS(1) Compared before the treatment, H-B, TFGS, DFNP and physical function score in FDI were all improved significantly in the Hegu 1 to 4 groups (all P < 0.05), but social function score in FDI was not obviously improved (all P > 0.05); all the scores in the control group were not evidently changed (all P > 0.05). (2) Compared with the control group, differences of H-B before and after treatment in the Hegu 1 to 4 groups, differences of TFGS in the Hegu 2 group and differences of DFNP in the Hegu 1 and Hegu 2 group were significantly improved (all P < 0.05). The differences of any scale among Hegu 1 to 4 groups were not significant (all P > 0.05), in which the most evident change was found in Hegu 2 group. (3) The total effective rate was 90.0% (9/10), 100.0% (10/10), 90.0% (9/10) and 80.0% (8/10) in Hegu 1 to 4 groups, which were significantly higher than 60.0% (6/10) in the control group (all P < 0.05).

CONCLUSIONAcupuncture at Hegu (LI 4) has affirmative clinical efficacy on central facial nerve paralysis after ischemic stroke, in which oblique insertion along the opposite direction of meridian for 5 s of twirling manipulation has the best clinical effect.
