Objective To observe the effects of the third-stage community-based rehabilitation program on functional recovery of stroke patients with hemiplegia. Methods 158 stroke patients with hemiplegia were divided into rehabilitation group and control group. Besides normal medicine and first-stage institution-based rehabilitation similar with that of control, rehabilitation group received a standardized third-stage community-based rehabilitation. They were assessed with the National Institutes of Health Stroke Scale (NIHSS), Fugl-Meyer Assessment (FMA), Modified Barthel Index (MBI) and Modified Rankin Scale (MRS) before, 1 month and 6 months after treatment. Results The scores of the FMA and the MBI of the rehabilitation group were higher than that of the control group (P<0.01), while were lower of the NIHSS and MRS in the rehabilitation group than in the control group at the end of the sixth month (P<0.01). Conclusion The third-stage community-based rehabilitation may improve the recovery of the stroke patients with hemiplegia.

BACKGROUND: Anterior and lateral columns of the femoral head integrity and stability have been reported to present a positive correlation with the prognosis of the osteonecrosis of the femoral head (ONFH) and efficacy of hip preserving. China-Japan Friendship Hospital Classification stressed that the retention of the anterior and lateral columns of the femoral head was of great importance to avoid the femoral head collapse, but there is little reported on its three-dimensional (3D) digital model.OBJECTIVE: To explore the method of establishing highly-simulated 3D model of China-Japan Friendship Hospital Classification for ONFH.METHODS: 3D reconstruction of normal and necrotic femoral head was established according to the CT and MRI of individuals with normal femoral head. A healthy adult male volunteer was selected and his CT image was collected; three adult male patients with types L1, L2 and L3 ONFH were selected, whose MRI images were obtained, respectively. 3D solid models were established based on CT and MRI data on Mimics 15.0, Geomagic Studio 13, Geomagic Design X, Solidworks2014 and Abauqus6.14 software. RESULTS AND CONCLUSION: A highly-simulated 3D model of L type ONFH was established, including the corticaland cancellous bones of ilium and proximal femur, articular cartilage, necrotic articular cartilage, muscles, joint capsuleand ligaments. It clearly showed the spatial structures of L type ONFH, by which different surgical programs could be compared in a virtual environment for selecting an appropriate treatment strategy to improve the success rate of hip preserving. The highly-simulated 3D model paves ways for surgical simulation and biomechanical analysis.

To evaluate the value of two histological quantitative methods of hepatic fibrosis: semiquantative scoring system (SSS) and image analysis by computer. The prophylactic and therapeutic effect of Ganzhifu on hepatic fibrosis induced by CCl4 were studied on a total 73 of specimens from liver tissue of rats. All specimen were analyzed quantatively by two methods of SSS marks and image analysis respectively. Difference between groups was compared and hydroxyproline (Hyp) content of each liver tissue was examined. Correlation analysis was done between SSS marks, image analysis and Hyp content. Both prophylactic and therapeutic study showed the same information. Results of SSS marks, image analysis and Hyp content were coincidence. It suggest that both SSS marks and image analysis were interrelated well with Hyp content (P < 0.01). The result suggests that both SSS marks of hepatic fibrosis and image analysis by computer can be taken as reliable histological quantitative method of hepatic fibrosis.

OBJECTIVE：To optimize the extraction technology of Zhideke granules. ME THODS：The extraction technology （water extraction ，alcohol extraction ，water extraction and ethanol precipitation ）of Zhideke granules was initially screened by ammonia-induced cough experiment and xylene-induced ear swelling experiment in mice. Based on its preparation route ，the immersion time of medicinal materials containing volatile oil was investigated with water absorption as index firstly. The single factor test was adopted to investigate the amount of water added and the extraction time taking the volatile oil yield as index to optimize the extraction technology of medicinal materials containing volatile oil. Taking the contents of irisflorentin and total flavonoids as indicators ，on the basis of single factor investigation ，orthogonal test was adopted to examine the influence of three factors including the amount of water added ，extraction time and extraction frequency ，so as to optimize the water extraction technology of Zhideke granules and the validation tests were conducted. RESULTS ：The results of pharmacodynamics experiment showed that the cough latency of mice in water extract low-dose and high-dose groups （6.34，12.68 g/kg，by crude drug ）and water-extraction alcohol-precipitation extract high-dose group （12.68 g/kg，by crude drug ）were significantly longer than those inmodel group ，and the number of cough within 2 minutes was significantly reduced （P＜0.05 or P＜0.01）. Compared with model group ， the ear swelling of mice in water extract low-dose and high-dose groups （6.34，12.68 g/kg，by crude drug），ethanol extract high-dose group （12.68 g/kg，by crude drug） and water-extraction alcohol-precipitation extract hig dose group （12.68 g/kg，by crude drug ） were decreased significantly （P＜0.05 or P＜0.01）. The swelling inhibition rates were 42.26％，55.08％，33.49％，51.56％，39.57％ and 44.36％ in low-dose and high-dose groups of water extract ，alcohol extract ， water-extraction and alcohol-precipitation extract respectively ，indicating that the water extract had better antitussive and anti-inflammatory effects. The optimal extraction technology of volatile oil was adding 5-fold water ，soaking for 30 minutes，and extracting for 3 hours. The optimal water extraction technology was adding 12-fold water ，extracting for 3 times after soaked for 50 min，lasting for 1 h each time. Results of 3 times of validation tests showed that average content of irisflorentin in the extract obtained by optimal technology was 76.47 μg/g（RSD＝ 2.15％，n＝3）and the average content of total flavonoids was 92.45 mg/g（RSD＝0.48％，n＝3）. CONCLUSIONS ：The optimal extraction technology of Zhideke granules is stable and feasible.

OBJECTIVE To analyze the metabolites of Zhideke granules and speculate its metabolic pathway in rats in vivo. METHODS Male SD rats were randomly divided into blank group and administration group （Zhideke granules， 9.45 g/kg）； they were given ultrapure water or relevant medicine， twice a day， every 6-8 h， for 3 consecutive days. Serum， urine and feces samples of rats were collected， and their metabolites were identified by UPLC-Q-Exactive-MS technique after intragastric administration of Zhideke granules； their metabolic pathways were speculated. RESULTS After intragastric administration of Zhideke granules， 16 prototype components （i.g. irisflorentin， baicalin， chlorogenic acid） and 11 metabolites （i.g. hydration products of kaempferol or luteolin， methylation products of chlorogenic acid， and hydroxylation products of baicalin） were identified in serum， urine and feces of rats. Among them， 8 prototype components and 4 metabolites were identified in serum samples； 10 prototype components and 7 metabolites were identified in urine samples； 8 prototype components and 5 metabolites were identified in the fecal samples. CONCLUSIONS The metabolites of Zhideke granules in rats mainly include baicalin， irisflorentin，chlorogenic acid， and the main metabolic pathways included methylation， hydroxylation， glucuronidation.
