Objective: To discuss the application principle in tuina manipulation for lumbar intervertebral disc herniation (LIDH) in Chinese literatures published in recent 30 years. Methods: The three major Chinese databases, Wanfang Academic Journal Full-text Database (Wanfang), Chongqing VIP Database (CQVIP) and China National Knowledge Infrastructure (CNKI), were searched to collect the studies of tuina manipulations in treatment of LIDH published in recent 30 years. Clustering analysis was applied to analyze the top 20 tuina manipulations for LIDH. Results: The top 20 most frequently used manipulations for LIDH were Gun-rolling, Rou-kneading, Dian-digital pressing, oblique Ban-pulling, An-pressing, Tanbo-plucking, Bashen-pulling and extending, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Dou-shaking, Yao-rocking, Ca-scrubbing, Pai-patting, post-extension Ban-pulling, Mo-rubbing, Zhen-vibrating, Nie-pinching, fist-back Ji-tapping, and dorsal Shen-extending methods. The involved manipulations can be divided into two categories by the treated body areas. One category is applied to the soft tissues, including Gun-rolling, Rou-kneading, Dian-digital pressing, An-pressing, Tanbo-plucking, horizontal Tui-pushing, Na-grasping, Anrou-pressing and kneading, Ca-scrubbing, Pai-patting, Mo-rubbing, Zhen-vibrating, Nie-pinching, and fist-back Ji-tapping methods. The other category is applied to bones and joints, including oblique Ban-pulling, Bashen-pulling and extending, Dou-shaking, Yao-rocking, post-extension Ban-pulling, and dorsal Shen-extending methods. Conclusion: Based on the treated body area, the tuina manipulations applied to treat LIDH are predominated by the ones performed on soft tissues, assisted by those on bones and joints. From the way of force exertion, the involved manipulations are majorly the swinging methods, followed by squeezing and pressing ones. The manipulations applied to bones and joints are predominated by the Ban-pulling ones, followed by the Bashen-pulling and extending ones.

BACKGROUNDAn increasing incidence of Crohn's disease has been found in China in recent years. Our study has been focused on evaluating the diversity of the clinical manifestations of Crohn's disease in order to improve early diagnostic accuracy and therapeutic efficacy.

METHODSThirty patients with active Crohn's disease were enrolled and their clinical data, including diagnostic and therapeutic results, were analyzed. Endoscopy combined with histological examination of biopsy specimens provided characteristic features of the disease. Transabdominal bowel sonography (TABS) was used for detecting intestinal complications. Nutritional supportive therapy was given to 20 subjects with active cases of the disease.

RESULTSMost patients were young adults with a higher proportion of females to males (ratio: 1.14:1). The disease affects any segment or a combination of segments along with the alimentary tract (from the mouth to the anus). In this study, the colon and small bowel were the major sites involved. Recurrent episodes of abdominal pain in the right lower quadrant and watery diarrhea were the most common symptoms. Granulomas were identifiable in nearly one-third (30.8%) of all biopsy specimens. In moderate cases of the disease, remission was achieved more quickly through the use of oral prednisone therapy than with SASP or 5-ASA. Beneficial effects on the host's nutritional status were observed. Immunosuppressives were used on an individual basis and showed variable therapeutic effects. Sixteen patients had surgery due to intestinal obstruction or failure to respond to drug therapies. Rapid improvement after surgery was reported.

CONCLUSIONEndoscopy (with biopsy) and TABS were both crucial procedures for diagnosis. SASP (or 5-ASA) and prednisone were effective as inductive therapies. Azathioprine has demonstrable benefits after induction therapy with prednisone. Surgery, as an alternative treatment, provided another effective choice in selected patients.

OBJECTIVETo observe the therapeutic effect of acupoint magnetic medicated plaster therapy on cirrhosis after hepatitis.

METHODSOne hundred and twenty patients with cirrhosis after hepatitis were randomly divided into 2 groups. The control group (n=60) were treated by the hepatic protective therapy (diammonium glyeyrrhiznate, Silymarin, compound Tanshin, vitamin E), and the treatment group were treated by the liver-protective therapy and acupoint magnetic medicated plaster therapy, for 2-6 therapeutic courses. Clinical symptoms, hepatic function, serum markers of hepatitis B virus and indexes of hepatic fibrosis were investigated.

RESULTSThe markedly effective rate and the total effective rate were 65.0% and 95.0% in the treatment group, and 43.3% and 91.7% in the control group, and the serum indexes of hepatic fibrosis decreased signficantly, with significantly diferences (all P < 0.05).

CONCLUSIONAcupoint magnetic medicated plaster therapy can improve clinical symptoms, rapidly restore hepatic function, decrease serum indexes of hepatic fibrosis in the patient of cirrhosis after hepatitis.

OBJECTIVETo evaluate the roles of total prostate specific antigen (tPSA), PSA density (PSAD) and biopsy Gleason score in predicting the pathologic stage of prostate cancer.

METHODSWe retrospectively analyzed the clinical data of 124 cases of pathologically confirmed prostate adenocarcinoma, and divided them into Groups A (n=48) and B (n=76) based on the results of bone scanning, CT, MRI, tPSA, PSAD and postoperative biopsy Gleason score, the former with extraprostatic infiltration or distant metastasis, while the latter without. We compared the above parameters between the two groups, screened the main factors that influenced the pathologic staging of prostate cancer by multivariate logistic regression analysis, and appraised the value of each of the parameters in predicting the pathologic stage of prostate cancer with a relative operating characteristic (ROC) curve.

RESULTSThe tPSA level and biopsy Gleason score were significantly higher in Group A than in B (P < 0.05). Multivariate logistic regression analysis showed that only tPSA could predict the pathologic stage of localized prostate cancer. The ROC curve exhibited that the combined use of tPSA and Gleason score had a better predicting value than other parameters (Gleason score + tPSA > tPSA > PSAD + tPSA + Gleason score).

CONCLUSIONTotal PSA remains a valuable predictor of the pathologic stage of prostate cancer, and its combination with Gleason score can further improve the predictive accuracy and contribute much to the treatment and prognosis of the disease.

OBJECTIVETo investigate the renal protective activity of Hsian-tsao Mesona procumbens Hemsl. water extracts in diabetic rats.

METHODSThirty Sprague-dawley female rats were randomly divided into three groups (n = 10 each), "control group" with intraperitoneal saline injection, "diabetic group" with 60 mg of intraperitoneal streptozotocin injection per kg of body weight and "Hsian-tsao group" with intragastric administration of Hsian-tsao extraction everyday for 4 weeks after intraperitoneal streptozotocin injection. The body weight and blood sugar were measured before and after model induction in the three groups. Thrombospondin-1 (TSP-1) expressions in the kidney were monitored by immunohistochemistry. Kidney ultrastructural changes were also analyzed by using transmission electron microscopy.

RESULTSBefore diabetic model induction, there were no significant differences among the three groups in body weight and blood sugar. Four weeks after the induction of diabetes, the differences became statistically significant. Electron microscopy also revealed disruption of the foot processes of the podocytes and other damages in diabetic group. These damages were significantly less severe in Hsian-tsao group when compared with the diabetic group. TSP-1 expressions in the kidney were significantly increased in both the diabetic group and Hsian-tsao group, but it was relatively lower in Hsian-tsao group than in diabetic group.

CONCLUSIONOur results showed that Hsian-tsao treatment in the diabetic rats effectively prevented the pathological alterations in the kidney and decreased the TSP-1 expression. It was suggested that Hsian-tsao had protective effect on the kidneys of the diabetic rats.
