Objective To investigate the significance to separate acute and chronic wards in a rehabilitation medicine department of generalhospital. Methods The patients discharged from acute wards from August 2012 to April 2013, when acute and chronic wards has beenseparated, were as group A (n=289), those from chronic wards were as group B (n=108). The patients discharged a year before the separation were as the control (group C, n=402). Their activities of daily living (ADL) when discharged, satisfaction and the time in the acute wards were observed. Results There was no significant difference in ADL between group A and group C (P>0.05), but it was between group B and group C (P<0.05). The patients more satisfied after separation (P<0.05), while the time in the acute wards decreased. Conclusion Separating the acute and chronic wards may improve the use of the medical resources and serve more patients. However, it improve the quality of care and satisfaction of the patients.

“Multi-component Chinese medicine” was derived from effective clinical prescriptions, which is similar to natural medicines, and its form is similar to the fixed-dose compounds. The adaptable indications mainly cast chronic, intractable, and complex diseases. Its research targets of pharmacology mostly are diseases, symptoms or pathological process. Vivo and vitro experiments can be used in its researches. Its dose-effect relationship mostly shows non-linear relationship, and three elements (dose, efficacy and syndrome) are involved. However, the comprehensive evaluation method is still in the exploratory stag. In the safety evaluation, there were few general pharmacological researches, and the basis of toxicity and the relationship between amount and toxicity need further study. In combined optimization aspect, including identification of components and component ratio optimization, many methods have been developed, but it still needs to be developed in theory and systemic integration. Pharmacological mechanism researches focus on the multi-component, multi-target, multi-pathway, and multi-pharmacodynamics aspects, combined with new ideas and new technologies, such as systems biology, network pharmacology, etc. But as multi-component medicine, it should also be studied about the correspondence and network relationships of component and target, with a purpose to explain the contribution of each component in overall mechanism.

Objective To determine the expression of cancer stem cell markers, CD133, CD44 and OCT-4, in small cell lung cancer cell line NCI-H82 and confirm the specific markers. Methods NCI-H82 cells were cultured, and the expressions of markers (CD133, CD44 and OCT-4) were detected by immunofluorescence staining. The immunohistochemistry was performed to detect the expressions of CD133, CD44 and OCT-4 in 79 tissues with small cell lung cancer. Results In NCI-H82 cells, the florescence was positive in CD133 and CD44 and negative in OCT-4. In the tissues, the expression of CD133 and CD 44 was related with tumor size, lymph node metastasis and clinical stage (P< 0.05), while OCT-4 was negative expression. Conclusion CD133 and CD44 might be the cancer stem cell markers of small cell lung cancer, which maybe have clinical significance on diagnosis and treatment.

Objective To assess the feasibility, safety and curative effect of permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy for the treatment of non-small cell lung carcinoma (NSCLC) in aged patients. Methods CT-guided permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy was performed in 46 patients with NSCLC, of whom 26 received primary treatment and 20 underwent renewed treatment. During the procedure, ~(125)I seeds were embedded into the tumor in all the patients. Three to five days after the implantation, GP scheme chemotherapy started. GEM (1 000 mg/m~2) was given (intravenously dripping for 30 min.) on the 1st, 8th and 15th day; DDP (30 mg/m~2) was employed on the 1st, 2nd and 3rd day, and recombinant human endostatin (Endostar, 7.5 mg/m~2) was administered (intravenously dripping for 3-4 hours) from the 1st to the 14th day. Every 28 days completed one treatment course. Two months after ~(125)I seed implantation, at this time the patient had received two courses of treatment, the short-term effect and the toxic side-effect were evaluated. Results Two months after the ~(125)I particles were embedded in the tumor, all the 46 cases were able to be evaluate for the curative effect. Of 46 patients, complete relief (CR) was seen in 12, partial relief (PR) in 24, stable (SD) in 6 and progression (PD) in 4, with an effective rate of 78.26%. Of 26 patients in the primary treatment group, CR was obtained in 7, PR in 15, SD in 3 and PD in 1, with an effective rate of 84.6%. Of 20 patients in the renewed treatment group, CR was seen in 5, PR in 9, SD in 3 and PD in 3, with an effective rate of 70.0%. Conclusion Permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy is an effective, safe and feasible treatment for NSCLC in aged patients.

This study aims to detect early changes of kidney in patients with primary hypertension by 3.0 T functional magnetic resonance imaging (fMRI). 26 patients with primary hypertension (hypertension group) and 33 healthy volunteers (control group) underwent conventional and functional magnetic resonance scans, which included blood oxygen level-dependent (BOLD) MRI, diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI). We measured renal cortical thickness (CT), parenchymal thickness (PT), and functional values of renal cortex and medulla including R2* value, apparent diffusion coefficient (ADC) value and fractional anisotropy (FA) value in each group, and then calculated the cortical/parenchymal thickness ratio (CPR). Compared with those in the control group, CT and CPR in hypertension group were larger (P < 0.01), cortical and medullar R2* values increased (P < 0.01) whereas medullar FA values decreased (P < 0.05). It could be well concluded that noninvasive 3.0 T functional MRI would have important clinical significance in identifying early abnormalities of kidney in hypertension patients.
