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.

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 validate the predictive power of the 5th and 6th editions of TNM staging system (TNM-5, TNM-6) in a Chinese patient cohort with hepatocellular carcinoma (HCC) sized > or = 5 cm after radical hepatectomy.
METHODSConsecutive 121 patients with HCC sized > or = 5 cm undergoing radical hepatectomy between January 1995 and December 2002 were included. The impact of clinicopathological variables on prognosis was determined by univariate and multivariate analyses, after excluding 2 perioperative deaths.
RESULTSIn univariate analysis, TNM-5 stage did not show prognostic significance for overall or disease-free survival, as opposed to TNM-6 stage, Edmondson-Steiner grade, portal vein tumor thrombosis (PVTT), vascular invasion, satellite nodule, Child-Pugh grade, and hepatitis B surface antigen (HBsAg) positivity. When these significant variables were entered in multivariate analysis, Edmondson-Steiner grade was the sole independent prognosticator for both overall and disease-free survival, whereas Child-Pugh grade independently influenced disease-free survival. However, TNM-6 stage lost its predictive potential in multivariate analysis.
CONCLUSIONSNeither TNM-5 nor TNM-6 staging system is revealed to be independently prognostic in patients with HCC sized > or = 5 cm after radical hepatectomy. Therefore, TNM-6 calls for more support in many subsets of HCC patients.

OBJECTIVETo summarize the experience of surgical treatment for cervical esophageal carcinoma.
METHODSClinical and follow-up data of 82 patients with cervical esophageal carcinoma undergone surgical treatment in Henan Provincial Cancer Hospital from Dec. 1993 to Dec. 2005 were analyzed retrospectively. The difference of the therapeutic regimen and 5-year survival rate of these patients were evaluated.
RESULTSBefore 1997, patients mainly underwent surgical therapy solely (27 cases). After 1997, 50 cases received surgical therapy following neoadjuvant radiotherapy (multimodality group), except 5 early-stage cases received surgical therapy solely. Seventy-three patients underwent esophagectomy without thoracotomy, including 21 cases of invert-stripping of the esophagus, and 52 cases of blunt denudation of esophagus. Nine patients underwent transthoracic esophagectomy. Concurrent monolateral or bilateral cervical lymph node dissection accounted for 14 cases and combined organ resection 12 cases. No serious hemorrhage and tracheal or bronchial tearing occurred. No hospital death occurred. Postoperative complications were found in 14 patients, and the incidence of complication was 19.5%. In sole surgery group, upper incised margins of 5 patients were confirmed to be positive. The laryngeal function of 26 patients in sole surgery group was preserved, while 47 patients in multimodality group preserved. Lymph node metastasis occurred in 14 cases, including 13 cases cervical lymph node metastasis (monolateral 9, bilateral 4) and 1 case of upper mediastinal lymph node metastasis. During follow-up, 3 patients were lost. The total 5-year survival rate was 43%. The patients in multimodality group had higher 5-year survival rate as compared to those in sole surgery group. (50.2% vs 33.9%,chi(2 )=7.17,P=0.007). The 5-year survival rates of patients with transthoracic esophagectomy, esophagectomy plus concurrent monolateral or bilateral cervical lymph nodes dissection or combined organ resection were 36.5%, 45.8% and 33.3% respectively. All the 5-year survival rates of these subgroups were lower as compared to multimodality group.
CONCLUSIONSFor patients with early stage cervical esophageal carcinoma and with proximal end of residual normal esophagus longer than 2 cm, the optimal therapy should be surgery. For most of the patients, surgery combined with neoadjuvant radiotherapy is the ideal therapeutic strategy, which can lower the risk of positive revised margin, improve the possibility of preserving the laryngeal function and result in the improvement of 5-year survival rate. Esophagectomy without thoracotomy should be preferred. Combined organ resection or bilateral lymph node dissection should be chosen carefully because these operating procedures may lead to severe injury and function lose.
