Objective To study the compatibility of TCM prescriptions of TCM practitioners of all dynasties of Alzheimer disease (AD). Methods Amnesia, forgetting, dementia, and idiot were set as search words to retrieve relevant literature in Encyclopadia of Traditional Chinese Medicine. Prescription information was screened and standardized to build database. Frequency analysis and association rules were used to mine TCM prescriptions and compatibility rules. Results Totally 449 AD related prescriptions were selected, involving 682 Chinese medicinal herbs. The individual herb with the highest frequency was Ginseng Radix Rhizoma (192);the herbal pair with the highest frequency was Ginseng Radix Rhizoma-Polyhalae Radix (182);the herbal combination with 3 Chinese medicinal herbs with the highest frequency was Poria with Hostwood-Ginseng Radix Rhizoma-Polyhalae Radix (79);the herbal combination with 4 Chinese medicinal herbs with the highest frequency was Polyhalae Radix-Ginseng Radix Rhizoma-Poria with Hostwood-Glycyrrhizae Radix et Rhizoma (37). The results of association rules showed that Ginseng Radix Rhizoma-Polyhalae Radix, Ginseng Radix Rhizoma-Glycyrrhizae Radix et Rhizoma, and Ginseng Radix Rhizoma-Poria with Hostwood were commonly used compatibilities in AD related prescriptions. Conclusion Treatment of TCM practitioners in all dynasties for AD mainly chooses Chinese medicinal herbs with the efficacy of tonifying qi and soothing nerves. The compatibilities and combinations are reasonable and with certain representativeness.

Objective To investigate the value of retention rate of indocyanine green at fifteen minutes(ICGR15)during hemihepatectomy for evaluation of residual liver reserve function in patients with primary liver carcinoma.Methods During hemihepatectomy,ICGR15 was tested in 44 patients after the hepatic artery and portal vein of resected side were ligated.Child-Pugh score,Child-Pugh classification,and MELD score before operation were tested.After operation,the liver function condition was estimated.Results The incidence of liver dysfunction was significantly lower in ICGR150.05).ICGR15 and MELD score in normal liver function group were statistical lower than those in mild insufficiency of liver function group and severe insufficiency of liver function group(P

Objective To investigate the effect of auxiliary heterotopic partial liver transplantation in treating acute ischemic liver failure. Methods Auxiliary heterotopic partial liver transplantation was performed on pigs.The pigs were divided into two groups.Group I: The host′ liver was preserved in situ, liver artery was ligated, portal vein was constricted,and donor patial right liver was transplanted under the right lobe of the liver of the host.Portal venous blood supply was constructed only, and arterial blood supply was not constructed .Group B:Except both arterial blood supply and portal venous blood supply of the donor liver were constructed, and the other operative procedures were as the same as in Group A. The living condition, liver function, blood supply, pathology and bile secretion of the donor liver were observed. Results The survival rates in Group B before and after operation were higher than that in Group A .Serum bilirubin(SB) after the operation was higher than that before the operation in Group A, but showed no change in Group B.After the operation, SB in Group A was higher than that in Group B. In Group A, the donor liver didn't secret bile,and hepatocytes were necrosis.In Group B, the bile secretion and blood supply of donor liver were good,and hepatocyte of the donor liver were alive and proliferating actively.The hosts' liver was necrosis obviously in both groups. Conclusions Hosts' liver artery ligation and portal vein constriction can result in acute ischemic liver failure.Auxiliary heterotopic partial liver transplantation is effective in correcting liver failure.The good arterial blood supply must be constructed in the donor liver to get good donor liver quality.

Objective To explore the methods and outcome of comprehensive therapeatic for primary liver cancer. Methods Various therapeutic methods and outcome of 265 patients with primary liver cancer admitted in the last five years, were analyzed retrospectively .The group consisted of 238 male, and 27 female patients. The average age 47.5 years. Operation was performed in 215 cases and non-operative treatment is 50 cases. Operative treatment included resection of hepatic cancer and/or adjuvant therapy. Non-operative therapy included transcatheter hepatic chemo-embolization(TACE),percutaneous ethanol injection (PEI)、drug delivery system(DDS)、cryosurgery、radiofrequency ablation(RFA). Results The resection rate, and mortality and morbidity rates were 57%(215/377), 74.9%(161/215), 0.5%(1/215), and 19% respectively. The overall 1-,2-,3-year survival rate were 78.9 %,59.3%,33.5%, respectively, in patients who received comprehensive treatment centered around surgical resection, and 62.3%,32.3%,22.8%, respectively, in 45 patients who received non-surgical resection treatment. Conclusions Liver resection combined with other nonoperative modalities are ideal ways to treat primary liver cancer at the present time, and for different stages of primary liver cancer different treatment modalities are used.

BACKGROUND:Calcium phosphate cement and recombinant human bone morphogenetic protein-2 both have bone osteoinductivity. Maybe both of them could promote repair of tendon-to-bone interface damage. OBJECTIVE:To evaluate the effect of calcium phosphate cement-II containing recombinant human bone morphogenetic protein-2 on tendon-to-bone interface healing after rotator cuff injury . METHODS: Twenty-seven adult healthy rabbits were enroled in the study. The tendon-to-bone interface of the bilateral shoulder joints was taken from three rabbits as normal group, and the bilateral shoulder joints of the other 24 rabbits were subjected to acute rupture of the rotator cuff and tendon-to-bone reconstructive surgery as experimental group (n=12) and control group (n=12). Rabbits in the experimental group were treated with calcium phosphate cement-II, while those in the control group treated with nothing. Specimens were colected at 2, 4, 8 postoperative weeks for biomechanical test. RESULTS AND CONCLUSION:The maximum tensile strength of the rotator cuff in the experimental group was higher than that in the control group (P < 0.001), but lower than that in the normal group (P < 0.001). At postoperative 8 weeks, the rigidity of rotator cuff of the experiment group was higher than the control group (P < 0.001) but lower than the normal group (P < 0.001). These findings indicate that calcium phosphate cement-II can improve the maximum tensile strength and rigidity of rabbit tendon-to-bone interface in the early postoperative period, enhance tendon-to-bone interface binding force, and promote tendon-to-bone interface healing.

Objective:To develop the Abusive Behavior Scale for Superiors under the Chinese context (ABSSC) and test its validity and reliability.Methods:Based on literature analysis and the open questionnaire survey in 32 employees,this study defined the construct of ASBSS,and compiled the preliminary questionnaire.A sample of 200 employees coming from companies was selected for item analysis.A sample of 445 employees was investigated with this questionnaire,223 of them were assessed for exploratory factor analysis and 222 of them were assessed for confirmatory factor analysis and internal consistency test with 2 week interval.Results:The ABSSC consisted of 11 items in 3 factors,which were neglect and slander,obstructionism and hard on subordinates.The 3 factors explained 55.45％ of the total variance.Furthermore,the result of CFA indicated that the model fitted the data with well constmct validity (RMSEA =0.06,GFI =0.94,NFI =0.92,CFI =0.96,IFI =0.96).The Cronbach α coefficient of the whole scale and its three facts were 0.87,0.79,0.78,and 0.76,respectively.Conclusion:It suggests that the Abusive Behavior Scale for superiors under the Chinese context (ABSSC) is reliable and valid enough to be applicable to measure superiors' abusive behavior under the background of Chinese culture.

The secretion and localization of epididymal specific proteins ESP-1, ESP-2 were systematically studied by the PAGE-western blot and ABC immunocytochemical technique in the epididymis of the rabbit. The results indicated that ESP-1 and ESP-2 represented the rabbit epididymal specific proteins of 42 kd and 20 kd, respectively. They were immunoeytochemically negative in the testis, heart, liver, spleen, lung, kidney and skeletal muscle of the rabbit as well as testis and epididymis of the rat. However, in the rabbit epididymis, except the initial segment ESP-1 and ESP-2 were started to be positive from caput segment. The ESP-1 was displyed in the supranuclear area of the principle cells, while the ESP-2 was distributed evenly in the whole cytoplasm of it. Subsequently, the most heavy positive reaction was demonstrated in the corpus epididymis and the proximal segment of cauda. In contrast of the caput, the stereocilia of principle cells and lumen sperms of the cauda epididymis were positive also. However, in the distal segment of cauda the positive reaction in cytoplasm of principle cells was gradually decreased and became disappeared completely soon, while the stereocilia of it still remained heavy positive even in that of vas deferens. The epithelium of prostate gland and seminal vesicle were negative. These results indicated that both ESP-1 and ESP-2 were secretory proteins produced mainly in the principle cells of the corpus epididymis. After releasing into the lumen, they took part of epididymal fluid and might bind on the sperm to regulate sperm maturation. The possible physiological significance of ESP-1 and ESP-2 was discussed.

Objective To investigate the clinical characteristics and surgical treatment for primary presacral tumors.Methods The clinical data of 42 patients of primary presacral tumors from January 2013 to May 2015 were analysed retrospectively.Results Of the 42 patients,16 cases were asymptomatic while 26 patients had discomfort at the sacral or abdominal region,or difficulty in urinating or defecation.90％ of the cases were digital rectum examination (DRE) positive.Among the 42 patients 36 cases underwent surgical treatment,1 case underwent radiotherapy,5 cases refused surgical treatment.Among those receiving surgical resection,28 cases had trans-abdominal surgery and 4 cases had trans-sacral surgery,while 3 cases had trans-abdominal & trans-sacral surgery,1 case had trans-abdominal and perineal surgery.Tumors were completely resected in 31 cases,and palliatively resected in 5 cases.3 cases suffered from intra-operative presacral hemorrhage.1 case with delayed hemorrhage required surgical intervention.2 cases from incision infection recovered after wound disinfection and dressing.3 cases had postoperative hip or leg numbness;1 case with high fever was cured by intensive antibiotics treatment.Conclusion The low incidence of presacral tumors makes early detection difficult.A diagnosis can be obtained by a positive DRE combined with CT or MRI results.Resection is a therapy of choice after biopsies.
