Cytotoxic substances and ionizing radiation can easily induce DNA damage, and double strand breaks (DSBs) are the main form of DNA damage. DNA damage can activate intracellular DNA damage responses and further induce related biological effects, such as DNA damage repair and cell cycle arrest. Homologous recombination (HR) is the primary DSB repair mechanism in eukaryotes. Abnormal expression of Rad51C, which is a key factor in the HR pathway, may result in DNA repair disorder, genomic instability, and eventually lead to tumor formation. In recent studies, researchers considered Rad51C as a potential target for cancer treatment. We reviewed the research progress on Rad51C in DNA damage repair and radiotherapy.

We developed a rehabilitation system by using the virtual reality technique and the Kinect in this paper. The system combines rehabilitation training with HMI and serious game organically, and provides a game and motion database to meet different patients' demands. Extended interface of game database is provided in two ways: personalized games can be developed by Virtools and Flash games which are suitable for patients' rehabilitation can be download from the Internet directly. In addition, the system provides patients with flexible interaction and easy control mode, and also presents real time data recording. An objective and subjective evaluation method is proposed to review the effectiveness of the rehabilitation training. According to the results of short questionnaires and the evaluation results of patients' rehabilitation training, the system compared with traditional rehabilitation can record and analyze the training data, which is useful to make rehabilitation plans. More entertainment and lower cost will increase patients' motivation, which helps to increase the rehabilitation effectiveness.

Purpurin is a common component ofRubia cordifolia L. The study on its molecular target was useful for elucidating the therapeutic material basis and action mechanism ofR. cordifolia. HT-29 cells were used in the cell culture. The highly expressed G Protein-coupled Receptor-35 (GPR35) agonist was used as target. The label-free optical biosensor cellular assay was used to investigate the agonist activity ofpurpurin at an endogenous receptor. The results showed thatpurpurin can cause DMR response in HT-29 cells. And the DMR response curve type was consistent with zaprinast. Its EC50 was 6.142± 0.189μmol·L-1. In addition,purpurinhad desensitization effect on GPR35 agonist zaprinast in HT-29 cells. GPR35 agonist ML145 blocked the DMR ofpurpurin. It was concluded thatpurpurinwas the GPR35 agonist.

Objective To evaluate the efficacy of light-emitting diode (LED) irradiation at 530 nm,630 nm and 850 nm in the treatment of photoaged skin.Methods A total of 14 adults with photoaged extensor forearm were recruited in this study.Three areas were selected at the extensor forearm in each of these subjects and received LED irradiation at 530 nm,630 nm and 850 nm,respectively,thrice a week for 12 sessions.Dermoscopy was used to visualize these areas before and after the irradiation,the Corueometer CM 825 to measure stratum corneum (SC) hydration,Tewameter TM 300 to determine transepidermal water loss (TEWL),and CM-2600d spectrophotometer to measure L* value and melanin index (MI).Tissue specimens were obtained from these areas irradiated with LED at 530 nm (n =5),630 nm (n =5) and 850 nm (n =4) separately before and 6 weeks after the initial irradiation,and subjected to histopathological examination.Results Both skin texture and pigmentation were improved in 10 and 7 testees after 12 sessions of LED irradiation at 630 nm and 850 nm,respectively,but the skin texture became rougher and pigmentation was increased in 7 testees after LED irradiation at 530 nm.After LED irradiation at 630 nm and 850 nm,the testees experienced an obvious increase in SC hydration ((37.9 ± 7.7) au and (34.5 ± 7.1) au at 6 weeks after the initial irradiation vs.(33.1 ± 6.1) au and (32.0 ± 7.0) au before irradiation,both P ＜ 0.05),but a significant decrease in TEWL value ((9.8-± 2.5) and (10.9 ± 2.5) g·m-2·h-1 at 6 weeks after the initial irradiation vs.(14.0 ± 1.8) and (14.2 ± 2.6) g·m-2·h-1 before irradiation),with no significant changes in L* value or MI (both P ＞ 0.05).No evident alteration was observed in SC hydration or TEWL value (both P ＞ 0.05),while the L* value significantly decreased (P ＜ 0.05) and MI increased (P ＜ 0.05) after LED irradiation at 530 nm.Histopathological examination showed photo-induced denaturation of collagen fibers and elastic fibers in the dermis of these subjects before irradiation,as well as nascent collagen fibers and elastic fibers in a more dense and regular arrangement after irradiation at the three wavelengths.Conclusions LED irradiation at both 630 nm and 850 nm can improve the appearance and barrier function of,and stimulate the proliferation and rearrangement of collagen fibers and elastic fibers in,photoaged skin,while LED irradiation at 530 nm increases skin pigmentation.
