Objective To observe the effects of Buyang Huanwu Decoction(BHD)on collateral circulation of patients with acute cerebral infarction(ACI)through transcranial Doppler sonography(TCD). Methods The randomized controlled trial methods were applied, and 80 ACI patients were randomly divided into treatment group and control group, 40 cases in each group. Two cases from each group were dropped out, and the left 38 cases of each group were included into the analysis. The control group was treated with the standardized western medicine regimen, and the treatment group was given BHD orally on the basis of treatment for the control group. The treatment for the two groups covered 7 days. On treatment day 3 and 7, TCD was adopted to investigate the blood flow velocity of the responsible vessels and the improvement of collateral circulation compensation. On treatment day 7, the scores of National Institute of Health Stroke Scale(NIHSS) in the two groups were compared. Results (1) On treatment day 3, collateral circulation improvement occurred in 12 patients(accounting for 31.58%)from the treatment group , and on treatment day 7 , the improved cases increased to 16(accounting for 42.11%). In the control group , 3 cases(7 . 89%) were improved on treatment day 3 , and 4(10 . 53%) improved on treatment day 7. The treatment group had better effect on improving collateral circulation than the control group, the difference being significant(P<0.01). (2) In the treatment group, 9 cases had increased blood flow velocity(Vm) of the responsible vessels on treatment day 3, and 11 cases had the increase on treatment day 7. In the control group, Vm increase occurred in one case both on treatment day 3 and 7. The treatment group had better effect on increasing Vm than the control group, the difference being significant(P<0.05). (3) On treatment day 7, NIHSS scores were decreased in both groups(P<0.05 or P<0.01), and the decrease of the treatment group was superior to that of the control group(P<0.01).(4) No adverse event was shown in the two g roups during the treatment. Conclusion BHD can constantly improve the blood flow velocity of the responsible vessel and promote collateral vessel building , which results into the recovery of the impaired neural function.

The objective of this article was to deliberate the relationship between trace elements and "Qi and blood" theory of traditional Chinese medicine by studying the similarities and differences in the contents of trace elements in SiJunzi decoction and Siwu decoction. Experiments indicate that there were some similarities and differences in the contents of trace elements in SiJunzi decoction and Siwu decoction, and it is very similar to "Qi and blood" theory of traditional Chinese medicine. When the Chinese herbs were decocted, the trace elements of Chinese herbs do not get into medicated solution uniformly. Different elements enter into the medicated solution in different periods of time and batches. It point out that the theory of methods of decocting Chinese herbs has a certain basis. These experiments remain existing some questions and doubts,it is worth to do some further related experiments and to be researched furthe.

Objective To evaluate the feasibility of testing the high methylation of ppENK gene in stool with methylation-specific polymerase chain reaction (MSP) assay in pancreatic cancer diagnosis.Methods Twenty-four fresh stool samples of pancreatic cancer patients and six healthy control samples were collected.The methylation status of ppENK gene in all the stool samples was detected by MSP assay.The positive rate of wild-type ppENK gene in all the stool samples was determined by polymerase chain reaction (PCR).And 10 non wild-type ppENK gene negative pancreatic cancer samples were collected,and K-ras gene mutation was detected by PCR-restriction fragment length polymorphism (RFLP).The single cell suspension of pancreatic cancer PC3 cell line was added into stool sample from the same healthy individual,the positive rate of ppENK gene methylation was detected by MSP assay.The minimum number of pancreatic cancer cell was calculated when methylation was positive.Results The rate of methylation detection in 30 samples was 0 (0/30); and the rate of non-methylation detection was 10％ (3/30).The rate of wild-type ppENK detection was 6.7％ (2/30).By PCR-RFLP assay,eight were successfully amplified and seven had mutation in 12th code of K-ras gene in 10 selected wild-type ppENK gene negative pancreatic cancer samples.The minimum number of pancreatic cancer cells needed for ppENK methylation band positive detected by MSP was 50 cell/ml.Conclusion Detecting ppENK gene methylation status in stool samples of pancreatic cancer patients by MSP assay has not yet become the method of pancreatic cancer screening and diagnosis.

Objective To comprehend the clinical characteristics and treatment of primary hepatic amyloidosis.Methods A total of 10 cases of primary hepatic amyloidosis included. 4 cases from Peking Union Medical College Hospital and 6 cases from other hospitals.reported in the literature in recent 20 years were reviewed,Results (1)The frequent clinical symptoms related to primary hepatic amyloidosis presented as hepatomegaly(90%),abdominal distension(80%),shifting dullness(60%),anorexia(50%),fatigue(40%),edema(40%),weight loss(40%) and abdominal pain(30%).(2)Laboratory tests revealed elevated serum alkaline phosphatase which was (558.3?517.2)U/L,and other liver function involvement were rare:six patients(85.7%)had either a serum or urine monoclonal protein.(3)Liver biopsy is golden standard.The amyloid deposition was mainly located at sinusoida(4 casese,57.1%),and only 2 cases was at vascular(28.6%).Complication of bleeding after liver biopsy was reported(1 case).(4)The classical therapy scheme was melphalan and prednisone,four cases died from liver function failure and infection.Conclusion The clues to the diagnosis of primary hepatic amyloidosis include elevated monoclonal protein,hepatomegaly and an unexplained elevated serum alkaline phosphatase level which is not parallel with other liver functions.Live biopsy is golden standard.The treatment scheme include melphalan and prednisone,but its prognosis is poor.

Objective To probe the differences and similarities of clinical feature between alcoholic and biliary chronic pancreatitis (CP) and their therapy. Methods Retrospective analysis of the clinical features was made in 110 cases of CP in Peking Union Medical College Hospital from 1991 to 2000. Results ① In 110 cases of CP, the clinical manifestations were abdominal pain (85.4%), diarrhea (22.7%), calcification of pancreas (13.6%), and pseudocyst of pancreas (28.2%); 3 cases (2.7%) complicated with pancreatic carcinoma. ② The frequency of the different kind of clinical manifestations in alcoholic CP was higher than in biliary CP.③The frequency of diarrhea (29.1%),diabetes mellitus (41.9%) and calcification of pancreas (22.6%) in alcoholic CP was also higher than in those caused by bile duct system diseases (16.7%, 19.1% and 9.5%).④The response rate of medical treatment was 81.2%. Conclusions The clinical features and complications are more typical and occur earlier in alcoholic CP than those in biliary CP. With regard to management, medical treatment is less used than surgical therapy.

Objective The aim of this study was to investigate the association between methylation of ppENK and S100A4 and pancreatic carcinoma. Methods 31 samples of human tissues of pancreatic cancer and adjacent tissues, five pancreatic carcinoma cell lines and one sample of normal pancreas were collected. ppENK methylation status was detected by MSP and S100A4 methylation status was detected by COBRA. The expression of S100A4 and ppENK protein was investigated by immunohistochemistry and RT-PCR. The association of methylation status of ppENK gene or S100A4 with clinical parameters of pancreatic carcinoma was analyzed. Results No methlation of ppENK was detected in normal pancreatic tissue. SI00A4 gene was highly methylated. Methylation of ppENK was detected in 90.3% of the pancreatic carcinoma tissue in 31 patients; there were no correlation between the status of ppENK methylation with clinical parameters of pancreatic carcinoma. The hypomethylation rate of S100A4 gene was 71%, and it was only related to the serum level of CA 19-9 (P=0.011, OR=0.05) ; the expression rate of S100A4 protein in pancreatic cancer tissue was 87.1%, and the expression rates were correlated with the differentiation of the tumor, namely, poorly differentiated tumor highly expressed S100A4 protein. S100A4 hyomethylation was highly correlated with ppENK methylation (P=0.019). Methylated ppENK was detected in five pancreatic cancer cell lines, and there was no ppENK mRNA expression; S100A4 gene was hypomethylated, while S100A4 mRNA was highly expressed in five pancreatic cancer cell lines. Conclusions ppENK was hypermethylated, while S100A4 was hypomethylated in pancreatic cancer tissue.

Objective To investigate the therapeutic effect of immunodepressant on Crohn's disease (CD).Methods 105 patients with CD were collected from 1983 to 2006 in Peking Union Medical College Hospital.All of their clinical manifestations and therapeutic results were analyzed retrospectively.Results (1)The application of immunedepressant was significantly increased after the year of 2000 (34.7% vs 3.0%,P=0.000).(2)The application of immunodepressant and the clinical features of these patients were as fouows：①The number of patients with modcrate to severe CD were more than that with mild CD in those using immunodepressant (28.9% vs 0).②The use of immunodepressant was not related with the diseased site of CD.because there were no difference among the groups with lesion in small intestine (20.0%),colon(27.3%)and ileocolon(27.1%),P=0.726.③The serum albumin level of CD patients using immunodepressant was significantly lower than that of those not using(31.9 g/L vs 35.1 g/L,P=0.047).④The use of immunodepressant did not decrease the incidenee of operative treatment(38.5% vs 50.0%,P=0.320).(3)The rate of remission in 19 CD patients using azathioprine is 68.4%(13/19)and the percentage of neutrophil in the group with relief was lower than that without relief(0.76 vs 0.65,P=0.032).Conclusions Immunodepressant is playing more important role in the treatment of CD.The patients with moderate and severe CD with as well as lower serum albumin should be treated with immunodepressant as early as possible.Whether immunedepressant is necessary or not is not decided by the diseased site.CD patients with higher percentage of neutrophil have less therapeutic effect than those with lower.
