To explore the clinical efficacies of narrow-band ultraviolet B (NB-UVB) for atopic dermatitis (AD).Thirty AD patients (observation group) and 30 homochromous healthy volunteers (control group) were compared.The post-treatment scores of Scoring AD (SCORAD) and visual analogue scale (VAS) [(29.4 ± 9.5) & (3.2 ± 1.1) points] were lower significantly those pre-treatment [(60.7 ± 11.4) & 6.3 ± 1.6) points] (P ＜ 0.01).The pre and post-treatment serum levels of 25 (OH) D3 and 1,25 (OH)2D3 were detected with enzyme-linked immunosorbent assay (ELISA).The post-treatment serum levels of 25 (OH) D3 and 1,25 (OH) 2 D3 [(75.36 ± 23.28) mmol/L & (149.28 ± 45.56) nmol/L] were significantly higher than those pre-treatment in observation group [(36.24 ± 18.48) mmol/L & (97.68 ± 32.88)nmol/L] (P ＜0.01).There were no significant differences from those in group control[(69.84 ± 20.64) mmol/L & (147.36 ± 43.68) nmol/L] (P ＞ 0.05).And the pre-treatment serum levels of 25 (OH) D3 and 1,25 (OH)2D3 were all significantly lower in observation group than those in control group (P ＜ 0.01).Thus NB-UVB therapy is both safe and effective for AD and it can boost significantly the serum level of vitamin D3.

Exosomes are vesicles of endocytic origin released from different cell types under both normal and pathological conditions.Proteomics is an emerging discipline for studying composition and mechanics and interac-tion of proteins with regard to disease occurrence、cellular metabolism,etc.Progress of research on exosomes from tumor cell at proteomics technology platforms in aspect of clarifying mechanisms of shaping and sustaining micro-enviroment of tumor growth and survival and metastasis, induce tumor proliferation, Immunosuppressive effects or immune evasion, and discovering biomarker, makes a promising prospect of exsomes in clinical diagnosis and treatment.

Health reconstruction is an important part of post-earthquake reconstruction task. To do a better job in health reconstruction after a disaster, we should, based on previous experience and the characteristics of different periods, properly utilize the health resources for the disaster relief and exercise long-term management. And in a long run, we should, taking into consideration of the future health demands, plan the health reconstruction in the disaster areas. Emphasis should be made on the personnel training for epidemic prevention. Efforts should be made to fully recover the health system in the disaster area and the recovered health system should be better than that before disaster.

Objective:To evaluate the nasal safety of gastrodin nasal temperature-sensitive in situ gel through the studies on cilia toxicity in toads and mucosal irritation in rats. Methods:The toads were randomly divided into four groups, saline group, gastrodin in situ gel group, blank gel matrix group and sodium deoxycholate group, and the cilia toxicity was observed in vivo by a toad palate meth-od. The rats were randomly divided into three groups, saline group, gastrodin in situ gel group and blank gel matrix group, and the mucosal irritation was studied in rats through the observation of nasal mucosal pathological changes and behavioral indices. Results:Compared with the saline group, gastrodin in situ and blank gel matrix showed no notable effect on the cilia movement function in toads, and the effect on cilia movement of sodium deoxycholate showed statistically significant difference when compared with that of sa-line, gastrodin in situ gel and blank gel matrix (P<0. 01). During and after the treatment, no sneezing appeared in the rats. Com-pared with that in the saline group, the number of scratching nose in the gastrodin in situ gel group and blank gel matrix group in-creased (P<0. 05) without difference between the groups (P>0. 05), and after the 2-day withdrawal, that in the gastrodin in situ gel group and blank gel matrix group decreased significantly when compared with that at the last administration (P<0. 05) and showed no notable difference when compared with that in the saline group (P>0. 05). The number of inflammatory cells in the nasal mucosa in the gastrodin in situ gel group and blank gel matrix group increased complicated with congestion and cilia falling off, and after the with-drawal, the mucosal morphology in the three groups showed no significant difference. Conclusion:The local application of gastrodin in situ gel has high security, which is valuable to be studied further.

Objective:To study the pharmacokinetic parameters of gastrodin nasal in situ gel ( ISG) with the base of TMC-P407-P188-carbomer, and evaluate its brain-targeting ability preliminarily. Methods:Rats were used as the model animals. The experiment group was treated with gastrodin nasal in situ gel, and the control group was treated with gastrodin solution with intravenous administra-tion. The plasma sample and brain tissue ( cerebrum and cerebellum) were taken out at the predetermined time points, and the concen-tration of gastrodin in plasma and gastrodigenin in brain tissues were determined by HPLC to draw the curve of concentration vs time. The pharmacokinetic parameters such as MRT and AUC were calculated by 3P97 software. The bioavailability F (%) and the brain-targeting index BTI were compared between the groups. Results:The concentration of gastrodigenin in the brain tissues of grastrodin in situ gel was higher than that of gastrodin solution with intravenous administration (P<0. 05). AUC of cerebrum and cerebellum both increased significantly with BTI of 2. 38 and 1. 93, respectively. MRT increased by nearly two-fold in the gel group when compared with that in the control group, and F(%) increased significantly in cerebrum and cerebellum as well. Conclusion:Gastrodin nasal in situ gel with the base of TMC-P407-P188-carbomer has promising effectiveness. Meanwhile, it can improve the brain-targeting ability of gastrodin with sustained release.

With the developments of endoscopic and interventional techniques, the role of surgical treatment in some diseases is gradually replaced by endoscopic or interventional treatment.The word surgery may not preserve only for surgeons, therefore it is redefined.According to different interventional pathways, digestive surgery can be divided into two categories, although both are with similar surgical essentials as resection and repair. Serosa surgery is traditional surgery,characterized for its pathway from skin to visceral serosa and cavity, either by open or laparoscopic platform. Mucosa surgery performs endoscopic operations from natural orifice then mucosa surface.The intercrossing or merging of different disciplines is an inevitable trend for modern medical science, traditional disciplines may be replaced by disease-centered medical model combined with multiple disciplines and techniques.Facing challenges, digestive surgeons should be confidential and inclusive;facing competitions, digestive surgeons should be brave enough for innovation and cooperation, and always regard patients' interest as his first priority.A universal norm for various disciplines should be set up on the practice of evidencebased medicine;surgeons in different specialties should learn from each other, and reinforcing comple-mentary advantages from each other;creating a novel disease-centered multidisciplinary heahhcare model on the basis of fusion of different disciplines is the development direction of digestive surgery.

The degradation kinetics of chlorogenic acid (5-CQA), cryptochlorogenic acid (4-CQA), and neochlorogenic acid (3-CQA) in aqueous solution at 37 degrees C and different pH values (7.05, 7.96, 9.25) were investigated in the present work. The results indicated that 3-, 4- and 5-CQA tended to remain stable in acidic pH circumstance, and unstable in neutral and alkaline pH circumstance. With the increase of the alkalinity, the degradation of 3-, 4- and 5-CQA was increased leading to a less amount of total CQA and was satisfactorily described by the Weibull equation. Meanwhile, caffeic acid was not detected after the degradation of CQA. Moreover, the degradation of 3-CQA and 5-CQA tended to be converted to 4-CQA, and the degradation of 4-CQA tended to be converted to 3-CQA rather than 5-CQA. The comparison of the degradation kinetics parameters of 3-, 4- and 5-CQA at neutral and alkaline pH values showed that the orders of the rate constant (k) values were 4-CQA > 3-CQA > 5-CQA, while the orders of the degradation half life (t½) values were 4-CQA < 3-CQA < 5-CQA, indicating the orders of the stabilities of 3-, 4- and 5-CQA at 37 degrees C and neutral and alkaline pH values were 4-CQA < 3-CQA < 5-CQA.
