BACKGROUND: Geshu (BL 17) is one of eight influential points of blood, acting on tonifying blood, nourishing blood, activating blood circulation and resolving stasis.OBJECTIVE: To explore the effect of Geshu (BL 17) on activating blood circulation and resolving stasis in blood stagnation syndrome with acupuncture.DESIGN: Randomized controlled and normal controlled observations were designed.SETTING: Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.PARTICIPANTS: Totally 65 cases of blood stagnation syndrome were selected from inpatients in Department of Acupuncture and Moxibustion in Union Hospital affiliated to Tongji Medical College of Huazhong University of Science and Technology.METHODS: Totally 65 cases were randomized into experiment group (33cases) and the control (32 cases). In the control, the patent Chinese drug,longxuejie was administrated orally for activating blood circulation and resolving stasis, 4 tablets/time, 3 times/day, 15 days made 1 course of treatment. In experiment group, Geshu (BL 17) was localized bilaterally; after routine sterilization on the points, a filiform needle, 25 mm in length was inserted and manipulated with even technique after arrival of qi for 5 minutes. In 15 minutes of needle retaining, the needle was manipulated for another 5 minutes and retained for 10 minutes, and then, the needle was withdrawn. The treatment was given once a day. Radioimmunoassay (RIA)was applied to determine the levels of 6-K-P and thromboxane B2 (TXB2)in plasma. Criteria on clinical therapeutic effects: Being cured is determined by slight red tongue, retarded and forceful pulse, disappearance of limb pain, skin and mucosal ecchymosis and dysmenorrhea, basic recovery of motor function in hemiplegia and disappearance of numbness. Being effective is by dark red tongue, slightly hesitant pulse, alleviation of limb pain, reducing of skin and mucosal ecchymosis, alleviation of dysmenorrhea, partial recovery of motor function in hemiplegia and alleviation of numbness. No effect is by none of any change of clinical symptoms in comparison before and after treatment.MAIN OUTCOME MEASURES: ① Observation of therapeutic effects between two groups. ② Observation of plasma 6-K-P and TXB2 levels and 6-K-P/TXB2RESULTS: Totally 65 cases were all in the result analysis. ① Observation of therapeutic effects between two groups: The therapeutic effect in experiment group was higher remarkably than that in the control [be cured:(15,10); be effective: (13,11)]. ② Comparison of plasma 6-K-P levels: In experiment group, it was higher remarkably after treatment compared with that before treatment [(159.28±16.48), (117.25±16.47) μg/L, P < 0.05]. In the control, it was higher remarkably after treatment compared with that before treatment [(133.51±13.97), (114.64±16.39) μg/L, P < 0.05]. ③Comparison of plasma TXB2 level: In experiment group, it was lower remarkably after treatment compared with that before treatment [(98.21±11.38), (110.45±1067) μg/L, P < 0.05]. In the control, it was lower remarkably after treatment compared with that before treatment [(101.15 ±12.14), (109.21±11.58) μg/L, P < 0.05]. ④ Plasma 6-K-P/TXB2: In experiment group, it was higher remarkably after treatment compared with that before treatment (1.621±0.203, 1.101±0.316, P < 0.05). In the control,it was higher remarkably after treatment compared with that before treatment (1.322±0.216, 1.234±0.305, P < 0.05).CONCLUSION: Acupuncture on Geshu (BL 17) increases 6-K-P level and 6-K-P/TXB2 and reduces TXB2 level. It is explained that acupuncture on Geshu (BL 17) regulates imbalance of PGI2-TXA2 system in blood stagnation syndrome so that the blood circulation is activated and stasis is resolved.

OBJECTIVETo study the role of mitogen-activated protein kinase (MAPK) pathway in the action mechanism of PYM-induced KB cell apoptosis.
METHODSWestern blot analysis was used to investigate the expression of the mitogen-activated protein kinase.
RESULTSWhen treated with PYM in cultured KB cells, the extracellular signal-regulated kinase (ERKl/2) showed a dose-and time-dependent decreasing in phosphorylation status of these proteins through a western blot analysis, whereas protein levels of p38 MAPK remained unchanged.
CONCLUSIONSThe mitogen-activated protein kinase (MAPK) pathway may play an important ro1e in PYM-induced apoptosis of KB cells.

We studied immune modulation and antioxidant effects of wheat peptides on immunosuppressed mice. Mice were administrated with wheat peptides orally for 10 days and treated with cyclophosphamide at the 8th day. The indexes including serum hemolysin, plaque forming cells, spleen cells proliferation, liver antioxidant enzymes activties, malondialdehyde (MDA), scavenging serum 2,2-Diphenyl-1-picrylhydrazyl and *OH and macrophage phagocytic ability in vitro were measured to assess the immune functions and antioxidation abilities. In vivo study shows that cyclophosphamide significantly decreases serum hemolysin (HC50) and phagocytic function of macrophages. Simultaneously, liver superoxide dismutase, catalase activity and total oxidation capacity were decreased and malondialdehyde was increased. Wheat peptides could recover HC50 and spleen cell proliferation when orally administrated. Furthermore, they could also enhance serum 2,2-Diphenyl-1-picrylhydrazyl and *OH scavenging. In conclusion, wheat peptides can help body resist the stress related disorders in immune and antioxidant system.

Objective:To investigate whether the nutrition support team (NST) benefits esophageal carcinoma (EC) patients who are concurrently undergoing chemoradiotherapy. Methods: Between June 2012 and December 2013, 40 EC patients undergoing chemoradiotherapy were divided into the NST group and routine treatment (RT) group, with 20 patients in each group. At the end of chemoradiotherapy, the nutritional status, incidence of complications, and completion rates of radiotherapy were evaluated. The length of hospital stay (LOS) and cost were also compared between the two groups. Results:The nutrition and blood parameter values of the NST group were better (P<0.05) than those of the RT group. The incidence of complications was lower in the NST group (P<0.05) than that in the RT group. In addition, all patients in the NST group achieved the treatment plan, whereas five of the patients in the RT group interrupted or delayed the plan (P<0.05). The average LOS decreased by 3.8 d (P<0.05), and the hospitalization costs were reduced to 6300 RMB person-times (P>0.05) for the patients of the NST group. Conclusion: NST could maintain the nutritional status and improve the treatment compliance and tolerance of EC patients undergoing chemoradiotherapy, thereby shortening the LOS time and reducing the costs.

In search of the optimal preparation method for large-scale purification of human plasma fibronectin, we adopted affinity chromatography with gelatin and the Sepharose 4B activated with cyanogen bromide to purify fibronectin from type "C" plasma of healthy males, and scanned the best method under the conditions of different amount of plasma loading and different residence time in column. In a given column volume of gelatin, the absorbent was related with the plasma residence time in column and the total amount of plasma loaded. As a result, the optimal loading amount of plasma is 150 ml, and the residence time is 20 minutes. The preparation method, herein, has been proved to require small amount of plasma and yield large amount of fibronectin.

The postoperative symptom burden in patients with lung cancer is severe and adversely impairs their quality of life. Symptom management is the cornerstone of medical care. Patient-reported outcome (PRO)-based symptom management is being increasingly recognized as the best "patient-centered care" model in clinical practice. However, the precise implementation of this model in patients undergoing lung cancer surgery is hindered by the lack of a lung cancer surgery-specific scale, implementation standards, clinical application parameters and high-quality researches. The use of a precise and simple PRO scale and an electronic PRO platform may greatly improve the feasibility of implementing this model. Currently, the application of PRO-based symptom management in lung cancer surgery is still being explored and needs to be improved in clinical research and practice.
