BACKGROUND: Cassia seed acts on decreasing blood pressure and blood lipid, protecting liver and inhibiting bacteria. It is worth to carry on a further discussion on its effect of weight loss.OBJECTIVE: To observe the influence of cassia seed decoction drunk naturally on body mass of nutritional obese rats in physiological state.DESIGN: Completely randomized grouping was designed, in which, control experiment, analysis of variance and q test were applied in comparison among groups.SETTING: Cardiovascular Institute, Second Affiliated Hospital, Henan University of Science and Technology.MATERIALS: The experiment was performed in Cardiovascular Instutute,Second Affiliated Hospital, Henan University of Science and Technology from March 2004 to September 2004, in which, 27 male SD rats were employed and randomized into 3 groups, named normal control group, model group and cassia seed group, 9 rats in each one.METHODS: [1] In normal control, the rats were bred with basic forage(the contents of protein, fat, carbohydrate were 18.2%, 4.5% and 55.2%successively, with 14.54 kJ caloric each gram) and drank water naturally.In model group, the rats were bred with high nutritive forage (the contents of protein, fat, carbohydrate were 23.7%, 21.6% and 39.0% successively,with 19.56 kJ caloric each gram) and drank water naturally. In cassia seed group, the rats were bred with high nutritive forage and drank cassia seed decoction of various concentration naturally. The concentration of cassia seed decoction started at 10 g/L (equally contained 10 mg raw cassia seed each milliliter) and was increased by 100% concentration each day (10 g/L)till to 60 g/L on the 6th day. Since the 7th day, the concentration of 60 g/L was maintained till to the 7th weekend. [2] It was to record appetite and drinking quantity at definite time every day and calculate absorbed caloric(intake mass × caloric contained each gram). It was to measure body mass at definite time each week. On the 7th weekend, the body length of rat was measured and Lee's index was calculated [ 3√body mass (g)×103/body length (cm)]MAIN OUTCOME MEASURES: Influences of cassia seed on body mass, Lee's index, appetite, caloric and drinking quantity in nutritional obese rats.RESULTS: Twenty-seven rats all entered result analysis. [1] Body mass:that in model group from the 3rd to 7th week in experiment group was higher remarkably than normal control group (P < 0.05-0.01). That in cassia seed group from the 2nd to 7th week was lower remarkably than that in the model group (P < 0.05-0.01). [2] Lee's index: that in model group and cassia seed group on the 7th week of experiment was higher remarkably than that in the normal control group [(358.60±8.55), (341.84±7.29), (322.00±6.89) g/cm, P < 0.05-0.01] and that in cassia seed group was lower remarkably than that in the model group (P < 0.05). [3] Appetite: that in model group and cassia seed group was lower remarkably than that in the normal control group (P < 0.05-0.01) and that in cassia seed group was near to the control group (P > 0.05). [4] Absorbed caloric: that in model group and cassia seed group was higher remarkably than that in the normal control group (P < 0.05-0.01) and that in cassia seed group was near to the control group (P > 0.05). [5] Drinking quantity: that in cassia seed group was basically near to that in the model group and the control group (P > 0.05) and that in model group was near to the control group. It was indicated that cassia seed decoction at mass concentration of 60 g/L did not affect appetite.CONCLUSION: Cassia seed decoction at mass concentration of 60 g/L inhibits remarkably the increased body mass of nutritional obese rats and is free from influence on appetite.

Objective? To investigate the feasibility and safety of vacuum modelling pad for patients with lateral position in thoracic surgery to improve the convenience and comfortable experience for medical staff and patients. Methods? From May 2017 to March 2018, 100 patients who underwent thoracic surgery under general anesthesia with lateral position in the operating room of Sun Yat-sen University Cancer Center were randomly selected and divided into observation group(n=50) and control group (n=50) according to random number table. The polyurethane vacuum modelling pad was used for to secure the patients' position in the observation group, while the sand bag baffle was used to secure the patient's position in the control group. Position placement time and skin pressure blisters were recorded in both groups. Questionnaires were sent out after operation to collect the satisfaction of medical staff with this position. The patients' comfort was followed up within 24 hours after operation. Results? The position placement time in the observation group was (183.56±10.36) s, shorter than the control group with (290.80±14.71)s and the difference was statistically significant(P< 0.01); there were 11 cases of skin reddening under pressure and 2 cases of blister in the observation group, which is statistically different from the control group with 24 cases of skin reddening under pressure and 9 cases of blister(P< 0.05). Patients' comfort score was(6.72±0.39) in the observation group, higher than the control group with (6.02±0.44) and the difference was statistically significant(P< 0.01). In terms of the 4 items of "the convenient operation", "comfortable standing position", "patient safety" and"overall evaluation", the observation group scored higher than the control group with statistical differences (P<0.01); in terms of the "surgical field exposure" and "fasten effects", there was no statistical difference (P>0.05). Conclusions? The use of modelling pad for patient lateral position in thoracic surgery can not only prevent organ and skin damage and ensure patient safety, but also simplify the operation procedure, improve the comfort of standing position and the working efficiency and satisfaction of the medical staff.

【Objective】 To explore the correlation between CSAG1 expression and the prognosis and tumor-infiltrating lymphocytes in renal clear cell carcinoma (RCCC), and to predict the survival and tumor progression. 【Methods】 The gene expression profiles and clinical information of CSAG1 were downloaded from the Cancer Genome Atlas (TCGA). Based on the differential mRNA expression, GO annotation and KEGG pathway analysis were performed. The relationship between CSAG1 and tumor immune infiltration was assessed with Tumor Immunoassay Resource (Timer 2.0) database. The mRNA expression of CSAG1 in human RCCC specimens was validated with qRT-PCR. 【Results】 CSAG1 expression was significantly higher in RCCC tissues than in normal tissues (P<0.05). The qRT-PCR results revealed that the mRNA level of CSAG1 was consistent with that predicted by bioinformatic analysis. The KEGG analysis and GO annotation indicated high GSAG1 expression in RCCC was related to transmembrane transport, tricarboxylic acid cycle and lysosome. CSAG1 expression was positively related to the infiltration of pDC, aDC, CD8+ T cells, cytotoxic cells, TFH, TH1 cells, Tem, NK CD56dm cells, Treg and T cells, but negatively correlated with macrophage infiltration. 【Conclusion】 CSAG1 may be associated with poor prognosis of RCCC and become a potential immunotherapy target.
