This paper reflected Physician-Patient Relationship from the "Jing Liang-affair" and concluded four views:Part of medical professionals also belong to vulnerable groups,medical organizations belong to strong groups;compared to those reasonless patients who have over expectations on medicine,medical professionals belong to vulnerable groups too;The medical system should be the root of the deterioration of Physician-Patient Relationship;The burnout of medical professionals is very serious.

0.05).Statistical analysis showed that there was a correlation between the expression of CTGF and TGF-?RⅡ,FN,and collagen Ⅰ and Ⅲ protein,respectively. Conclusions The expression of CTGF and TGF-?RⅡ protein is up-regulated in PRM of PVR,which suggests that the activation of TGF-?RⅡ is involved in the production of CTGF,and CTGF is closely related to the production of ECM and play an important role in the pathogenesis of PVR.

?Objective: To estimate the effect of carboplatin activiated carbon particle delivery system (CP CH) in the treatment of oral carcinoma and its cervical lymph node metastasis. Methods: CP CH was prepared by absorption of carboplatin with activated carbon particles and injected into the submucosa around the tumors 72 h before operation in 6 patients with tongue or buccal squamous cell carcinoma (SCC) and metastasis in cervical lymph nodes,then extensive tumorectomy with neck dissection was conducted. The specimens of lymph nodes,primary carcinoma and blood were analyzed by microscope and plasma emitting spectrometry. Results:60 out of 70 (83.33%) lymph nodes obtained from the CP CH treated cases were found to be stained black by carboplatin.The carboplatin concentrations in lymph nodes and blood were (23.36 ?2.58) ?g/g and (1.76?0.32) ?g/ml respectively.Necrosis and degeneration were observed in SCC tissue.Conclusion:CH CP may be effective in the treatment of oral SCC with cervical lymph metastasis by providing high concertration and long lasting carboplatin in the lessions.

Objective To evaluate the parametric features of image textures on 18F-FDG PET/CT for the differentiation between malignant and benign pulmonary nodules and compare the diagnostic performance of these parameters with SUVmax.Methods 18F-FDG PET/CT images of 170 patients (102 males,68 females,age range:29-81 (mean 59)years) with pulmonary nodules were retrospectively evaluated.Eightynine pulmonary nodules (230 slices) were malignant and 81 (193 slices) were benign.The pulmonary nodules were contoured on CT images and mapped to the co-registered PET images.Thirteen parameters of textural features were extracted and SUVmax was measured.Logistic regression analysis was used to identify the significant texture parameters and create a regression model.The efficacy of the textural features and SUVmax to distinguish between malignant and benign pulmonary nodules was evaluated by ROC curve analysis.The textural features of squamous cell carcinoma and adenocarcinoma were compared via the Mann-Whitney u test.The sensitivity and specificity of the textural features and SUVmax for the differential diagnosis were compared with x2 test.Results Logistic regression model identified 4 textural features (skewness (β =1.7058),kurtosis (β =-1.0989),angular second moment (ASM,3 =-4.4140) and strength (β =0.5626) ; all P ＜ 0.05) to have significant correlation with the malignancy of lung nodules.The AUC of ROC curve was 0.775 (95％ CI0.732-0.819; P＜0.001) with the sensitivity of 89.6％ (206/230) and specificity of 50.8％ (98/193).ASM and strength had statistically significant differences between squamous cell carcinoma and adenocarcinoma [ASM:0.0303 (95％ CI 0.0392-0.0724) vs 0.0594 (95％ CI 0.0721-0.0947) ; strength:2.4714 (95％ CI 2.4632-4.1050) vs 1.5945 (95％ CI 1.9003-2.4652) ; u =3082.0 and 3115.0,both P＜0.01].The AUC of SUVmax-based diagnosis was 0.757 (95％ CI 0.711-0.802 ; P ＜ 0.001) with the sensitivity of 80.9 ％ (186/230) and specificity of 50.3 ％ (97/193) at a cut-off value of 2.5.The sensitivity of the textural features was superior to SUVmax in differentiating malignant from benign pulmonary nodules (x2 =6.903,P ＜ 0.01).Conclusions Image textural parametric features extracted from 18 F-FDG PET/CT are more sensitive to differentiate between malignant and benign pulmonary nodules compared to SUVmax.They might also be useful to discriminate between different pathological types of lung cancers.

Objective To explore the influence of different feeding methods on feeding tolerance and nutritional status of preterm infants.Methods Forty-eight cases of preterm infants were randomly divided into experiment group and control group,24 cases in each group.The experiment group adopt 24 hours continuous feeding by infusion pump,and the control group with syringe injection,with injection time of 3~5mins every 2 hours.The two groups were compared in terms of feeding tolerance,body weight and nutritional status.Results The feeding intolerance of experiment group was lower than that in the control group,weight and prealbumin were higher than those in the control group(P<0.05 or P<0.01).Conclusion The continuous feeding is the ideal feeding method,which can improve growth,feeding tolerance and nutritional status of preterm infants.

Zebrafish was selected as model animal, and glucocorticoid dexamethasone was used as a model compound to establish a rapid and high efficient osteopenia model. Zebrafish larvae at 4 days post fertilization (dpf) were exposed to a serial concentrations of dexamethasone solutions, and 0.5% DMSO was selected as the vehicle control group. All groups were incubated in 24-well plates (28.5 degrees C) until 9 dpf. In addition, effects of 10 micromol x L(-1) dexamethasone on preventing against osteopenia induced by etidronate disodium were also investigated. Zebrafish bones at 9 dpf were stained with alizarin red. Quantitative analysis of the stained area was performed by microscopic inspection and digital imaging methods to reflect the amount of bone mineralization. Results showed that dexamethasone group at 2.5, 10 and 25 micromol x L(-1) can decrease the staining area and the staining optical density values of zebrafish head bones when compared with the vehicle control group (0.5% DMSO), which suggested that dexamethasone can significantly reduce the zebrafish mineralized bone and the bone mineral density. Results also showed that 15 and 30 microg x mL(-1) etidronate disodium can increase the mineralized matrix of zebrafish head bone and prevent against osteopenia induced by dexamethasone. In conclusion, the study indicated that zebrafish can be an idea osteopenia model induced by dexamethasone.

Prednisolone-induced zebrafish osteoporosis model was used to explore the bone-strengthening effect of Jie-Gu-Tang (JGT). Zebrafish larvae of 5 days post fertilization (d.p.f.) were co-exposed with 25 μmol·L-1 pred-nisolone and a series of JGT solutions with a range of concentrations (0.025, 0.25, 2.5, 25 and 100 mg crude herb per liter). The 25 μmol·L-1 prednisolone was selected as the model group. Etidronate disodium (15 and 30 mg·mL-1) with 25 μmol·L-1 prednisolone was used as the positive group. And 0.5% DMSO was used as the vehicle control group. All groups were incubated in 24-well plates (28.5℃) until 10 d.p.f. Zebrafish skeleton at 10 d.p.f. was anes-thetized and fixed for staining with alizarin red. Quantitative analysis of the stained area was performed by microscop-ic inspection and digital imaging methods to reflect the amount of zebrafish head skeleton mineralization. The results showed that prednisolone group at 25 μmol·L-1 concentration can obviously decrease the staining area and the stain-ing optical density values when compared with the vehicle control group (0.5% DMSO). Compared with the model group, both etidronate disodium (15 and 30 mg·mL-1) and JGT (2.5, 25 and 100 mg crude herb per liter) can in-crease the mineralized matrix and integrated optical density (IOD) of zebrafish head skeleton significantly with dose-effect relationship. It was concluded that zebrafish osteoporosis model was successfully used in the evaluation on bone loss prevention and bone formation promotion of JGT, which provided basis for the reliability and reasonability of zebrafish model.
