BACKGROUND:The non-specific immune suppression method is generaly used for treatment of systemic lupus erythematosus, but poor prognosis, such as infection and high recurrence rate, exists.
OBJECTIVE:To evaluate the therapeutic effect of bone marrow mesenchymal stem cel transplantation on systemic lupus erythematosus in mice.
METHODS:Sixteen mice with systemic lupus erythematosus were equivalently randomized into control and experimental groups, or then subjected to passage 3 bone marrow mesenchymal stem cel transplantation or the equal volume of normal saline via the tail vein, respectively. Mouse urine samples were colected to detect urine protein levels by Bradford method. Blood samples from the tip of the mouse tail were extracted to detect serum anti-ds-DNS antibody concentration by radioimmunoassay. Mouse kidney tissues were taken and observed pathohistologicaly through hematoxylin-eosin staining and immunohistochemistry staining under microscope. Flow cytometry was used to detect the expression of CD4+CD25+T cels in the inner canthus blood, fresh spleen and thymus.
RESULTS AND CONCLUSION:Within 10 weeks after cel transplantation, the urine protein levels in the two groups were gradualy increased, and the rising velocity was higher in the control group than in the experimental group. From the 4th to 10th week, the urine protein levels in the experimental group were significantly lower than those in the control group (P < 0.05). In the control group, lymphocyte infiltration was visible in the kidney tissues with a few of plasmocytes, and pathological findings showed the mice presented with interstitial nephritis; in the experimental group, the mice had no pathological changes in the kidney. In the two groups, immune complexes were found in the mesangial area, which showed a patch-like distribution in the control group and a punctate distribution in the experimental group; the relative proportion of the occupied area in the experimental group was significantly lower than that in the control group. The expression level of CD4+CD25+T cels in the blood and thymus were significantly higher in the experimental group than the control group (P < 0.05), and the expression level of CD4+CD25+T cels in the spleen was slightly higher in the experimental group than the control group with no significant difference (P > 0.05). The serum anti-ds-DNA antibody concentration in the experimental group was significantly lower than that in the control group (P < 0.05). Taken together, bone marrow mesenchymal stem cel transplantation can improve the pathological damage in systemic lupus erythematosus mice, and has a certain therapeutic effect on systemic lupus erythematosus.

The purpose of this study was to develop a robotic system for image-guided percutaneous interventions using ultrasound (US) or computed tomography (CT) for needle biopsy, ablation, cryotherapy, and other needle procedures. The conventional operation of puncture was analyzed firstly, and a compact robot was then designed for manipulating a needle or other slender surgical instrument in the confined space. Its distinctive characteristic is the decoupled motion capability correlated to the positioning and orientation steps of the percutaneous intervention. This approach allowed each step of the intervention to be performed using a separate mechanism of the robot. One major advantage of this kinematic approach was patient safety.

ObjectiveTo observe the effect of Integrated Chinese-western three-stage rehabilitation on activities of daily living (ADL) in stroke patients. Methods60 stroke patients were randomly divided into the trial group and control group with 30 cases in each group. Patients of control group were treated with routine neurological interventions and three-stage rehabilitation, while those of trial group were administered resuscitating acupuncture therapy, scalp and body acupuncture in addition. All the patients were assessed with modified Barthel index (MBI) at the beginning, 1 month, 3 months, 6 months respectively after stroke. ResultsThere was no significant difference in ADL between the trial and control groups at the beginning, and both improved at the following period (P<0.01). At each of the following period, either the ADL scores (P<0.05) or the increase of the ADL scores (P<0.05) of the trial group were significant higher than those of the control group. ConclusionIntegrated Chinese-western three-stage rehabilitation could improve the ADL further for the stroke patients.

China Journal of Chinese Materia Medica 2004;29(11):1094-1098
By collecting and analyzing the information of the processing of Flos Sophorae in ancient and recent literatures, we discovered that such methods as steaming, boiling, stir-frying and baking had been used before Qing Dynasty. There were more than 10 kinds of different decoction pieces due to different subsidiary agents and distinction of processing degree. In modern times, besides stir-frying with vinegar used in Jilin, stir-flying with honey used in Henan and Shandong, being crude, yellowing by stir-frying and carbonizing by stir-frying are used in other places. This research has provided useful information for the modern processing study by summarizing the previous experiences earnestly.

BACKGROUNDPatient trust in physicians, which can be considered a collective good, is necessary for an effective health care system. However, there is a widespread concern that patient trust in physicians is declining under various threats to the physician-patient relationship worldwide. This article aimed to assess patient trust in physicians through a quantitative study in Shanghai, China, and to provide appropriate suggestions for improving the trust in China.
METHODSThe data from a survey conducted in Zhongshan Hospital and Shanghai Tenth People's Hospital, which are two tertiary public hospitals in Shanghai, were used in this study. Patient trust in physicians was the dependent variable. Furthermore, a 10-item scale was used to precisely describe the dependent variable. The demographic characteristics were independent variables of trust in physicians. Binomial logistic regression was employed to analyze the factors associated with the dependent variable, which was divided into two categories on the basis of the responses (1: Strongly agree or agree and 0: Strongly disagree, disagree, or neutral).
RESULTSThis study found that 67% of patients trusted or strongly trusted physicians. The mean score of patient trust in physicians was 35.4 from a total score of 50. Furthermore, patient trust in physicians was significantly correlated with the age, education level, annual income, and health insurance coverage of the patients.
CONCLUSIONSPatient trust in physicians in Shanghai, China is higher than previously reported. Furthermore, the most crucial reason for patient distrust in physicians is the information asymmetry between patients and physicians, which is a natural property of the physician-patient relationship, rather than the so-called for-profit characteristic of physicians or patients' excessive expectations.

ObjectiveTo investigate the expression of CD90 in human intrahepatic cholangiocellular carcinoma and its association with lymph node metastasis and poor prognosis. MethodsA total of 49 samples of intrahepatic cholangiocellular carcinoma tissue and 49 samples of adjacent tissue were collected after surgical resection in The Affiliated Hospital of Chengde Medical College from March 2013 to March 2016, and 40 normal liver tissue samples were selected as control. Immunohistochemistry was used to measure the expression of CD90 in each sample, and its association with clinical indices, survival, and prognosis of patients with intrahepatic cholangiocellular carcinoma was analyzed. The t-test was used for comparison of continuous data between two groups; the chi-square test was used for comparison of categorical data between two groups, the Kruskal-Wallis H test was used for comparison between three groups and further comparison between two groups. The Kaplan-Meier curve was used to analyze postoperative recurrence and survival, and the log-rank test was used for comparison. Results The moderately positive expression rate of CD90 was 65.31% in intrahepatic cholangiocellular carcinoma tissue, 30.61% in adjacent normal tissue, and 0% in normal liver tissue, suggesting that the intrahepatic cholangiocellular carcinoma tissue had a significantly higher moderately positive expression rate of CD90 than adjacent normal tissue and normal liver tissue (P<0.05). The expression of CD90 was associated with TNM stage and hilar lymph node metastasis in the patients with intrahepatic cholangiocellular carcinoma (χ2=12837 and 17.824, both P<0.001). The patients with negative/weakly positive expression of CD90 had significantly higher relapse-free survival rate and overall survival rate after surgery than those with moderately/strongly positive expression (χ2=3.845 and 4.152, P=0025 and 0.021). ConclusionCD90 is highly expressed in human intrahepatic cholangiocellular carcinoma tissue, which is associated with hilar lymph node metastasis and poor prognosis and plays an important role in tumor development, progression, and metastasis.
