OBJECTIVETo explore the functional brain localization with magnetic resonance imaging (MRI) after acupuncturing the Yuan-Source and He-Sea acupoints of Stomach Meridian of Foot-Yangming (ST).
METHODSThe study was performed in 30 healthy volunteers who underwent acupuncture at Yuan-Source acupoint (Chongyang, ST42) and He-Sea acupoint (Zusanli, ST36) (ST group). Ten of these were also underwent acupuncture at the non-acupoints as the control group. Blood oxygenation level dependent functional MRI was performed.
RESULTSIn the ST group, signal increasing areas were demonstrated in bilateral superior temporal gyri (Broadmann 22), bilateral supramarginal gyri (Broadmann 40), bilateral cerebellar hemispheres, bilateral cingulate gyri and isthmus of cingulate gyri (Broadmann 32, 30), bilateral superior parietal lobules (Broadmann 7); signal decreasing areas were shown in bilateral orbital gyri (Broadmann 11), bilateral temporal pole (Broadmann 38), right inferior frontal gyrus (Broadmann 47) and right medial occipitotemporal gyrus (Broadmann 36). In the control group, signal increases areas were demonstrated in superior temporal gyri, precentral gyri, cingulate gyri, thalamus, insula and cerebellum. The size, signal intensity and number of increasing areas in control group are less than in ST group.
CONCLUSIONCombined acupuncture of Yuan-Source and He-Sea acupoints of ST can activate and decrease the multiple brain regions of "splanchnic brain" and thus reach a new functional balance to relieve pain.

OBJECTIVETo determine the number of goblet cells, the change of MUC5AC expression in chronic obstructive pulmonary disease (COPD) patients and the relationship of smoking with goblet cell, MUC5AC, and lung function.
METHODSEighteen patients undergoing lung resections for a solitary peripheral carcinoma were classified by lung function as having COPD. Twenty patients with normal lung function served as the control group. Normal lobe bronchioles far away from the lesion site were taken for paraffin section. Goblet cells were identified by AB/PAS staining and the expression of MUC5AC in the paraffin's section was tested by immunohistochemistry.
RESULTSGoblet cell hyperplasia was observed in the COPD group. The positive rate of goblet cell in COPD group (0.20% +/- 0.10%) was significantly higher than that in the normal lung function group (0.13% +/- 0.06%, P < 0.05). The positive rate of MUC5AC expression in the COPD group (0.27% +/- 0.09%) was higher than that in the normal lung function group (0.20% +/- 0.10%, P < 0.05). The positive rate of goblet cell in smokers (27.93% +/- 9.00%) of the COPD group and normal lung function group was higher than that in non-smokers (17.70% +/- 9.37%, P < 0.05), while MUC5AC expression had no significant difference between smokers and non-smokers (17.88% +/- 6.44% and 10.88% +/- 7.10%, respectively).
CONCLUSIONFor COPD patients with declined lung function, there were goblet cell hyperplasia and increased expression of MUC5AC. MUC5AC expression up-regulation may due to goblet cell hyperplasia. Smoking may be an important factor for goblet cell hyperplasia.

Objective To determine factors affecting postoperative survival of elderly patients with hepatocellular carcinoma (HCC). Methods A retrospective analysis of consecutive 54 elderly patients undergoing hepatectomy for hepatocellular carcinoma from Jan 1995 to Dec 2002 was performed. The data were analyzed by Kaplan-Meier method and Cox regression. Results Univariate analysis and Cox regression showed Child Pugh grading, vessel invasion, satellite nodule formation, Edmondson Steiner grading, intrahepatic recurrence and distant metastasis all related to postoperative overall survival or disease-free survival of the elderly with hepatocellular carcinoma (all P

This study was aimed to investigate the efficiency of 4 different culture media for in vitro culture and expanding adult human bone marrow mesenchymal stem cells (ahBM-MSCs) so as to establish a protocol of culturing and expanding hBM-MSCs and provide exprimental basis for hematopoietic blood stem cell transplantation combined with BM-MSCs. BM-MSCs were obtained from 16 fresh adult human bone marrow aspirate by gradient centrifugation with Ficoll Paque, then cultured in DMEM/F12 with 10% umbilical cord blood serum, 10% fetal calf serum (FCS), human blood serum, and MesenCult culture medium. The surface antigens of BM-MSCs were detected by flow cytometry. BM-MSCs were differentiated into osteoblasts and adipocytes under culture in the conditioned medium special for osteogenesis, and adipogenesis and the differentiated MSCs were identified by morphological observation, immunophenotype and immunohistochemical staining. The results showed that BM-MSCs could be isolated from adult human bone marrow and cultured by all culture media. The effect of umbilical cord blood serum on BM-MSC proliferation and their purity were similar to that of MesenCult culture medium, but better than that of FCS and human blood serum. The positive rate of CD29, CD73, CD105 on BM-MSCs cultured in umbilical cord serum and MesenCult medium was higher than that in FCS and adult human serum (p < 0.05), and the positive rate of CD31 was lower than that in FCS and adult human serum (p < 0.05). The positive rate of BM-MSCs differentiated into osteoblasts and adipocytes under culture in the conditioned medium for osteogenesis and adipogenesis with umbilical cord blood serum and MesenCult culture medium was also higher than that in FCS and adult human serum (p < 0.05). It is concluded that BM-MSCs can be obtained by all the four methods. DMEM/F12 with 10% umbilical cord blood serum and MesenCult culture medium are better than the others for the purification and differentiation potency of BM-MSCs in vitro. The medium with umbilical cord serum is valuable for clinical application in HSCT.

OBJECTIVETo study the feasibility and validity of multi-modal serial therapy for primary liver cancer in senile patients.
METHODS153 senile primary liver cancer patients (>or= 60 years) were given multi-modal serial therapy from June 1993 to December 2000. Hepatectomy was performed in 37, deep cryosurgery in 32 and non-operative therapy in 84 (intervention as chief therapy in 81, combined local and intervention therapy in 3). The multi-course intervention therapy was given postoperatively in hepatectomy and cryosurgery groups, while bioimmunotherapy and traditional Chinese medicine were used in all groups.
RESULTSThe 1-, 3- and 5-year survival rates in the hepatectomy group were 78.4%, 46.4% and 35.7%, without operative mortality. The 1- and 3- and 5-year year survival rates in the cryosurgery group were 64.5%, 40.9% and 25.0% with mortality of 3.1%. Among patients with non-operative therapy, the 1- and 3- and 5-year year survival rates in intervention group were 47.5%, 23.5% and 4.3%. The operative mortality was 1.2%. The 3 patients who received combined local and intervention therapy have survived for 2.5, 3.8 and 7.1 years.
CONCLUSIONMulti-modal serial therapy with surgical treatment as the chief means, being precise in the effect and good in safety, is feasible and valid for primary liver cancer in senile patients.

OBJECTIVEMicroRNAs (miRNAs) play important roles in cell proliferation, differentiation and apoptosis. 1, 3, 4-tri-O-galloyl-6-O-caffeoyl-β-D-glucopyranose (BJA32515) is a new natural ellagitannin compound extracted from Balanophora Japonica MAKINO. The effect of BJA32515 on the expression of miRNAs in cancer cells has not yet been explored. Objective The present study was carried out to examine the changes in miRNA expression profiles in human HepG(2) hepatocarcinoma cells following BJA32515 exposure.
METHODSThe proliferation of BJA32515-exposed HepG(2) cells was assessed using a colorimetric assay (cell counting kit-8). The miRNA expression profile of the cancer cells was analyzed using a miRNA array and quantitative real-time PCR. Apoptosis was assessed by annexin V and propidium iodide staining.
RESULTSBJA32515 inhibited the cell proliferation and increased apoptosis in HepG(2) cancer cells. The exposure to BJA32515 also caused alterations in the miRNA expression profile in the cells, with 33 miRNAs upregulated and 59 down-regulated. The up-regulation of let-7a and miR-29a and the down-regulation of miR-373 and miR-197 were verified by quantitative real-time PCR. CONCLSION: BJA32515-modifed miRNA expression may mediate the antiproliferative effect of this compound in HepG(2) cancer cells.
