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.

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.

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 explore the association of -1195G > A genetic variant in the promoter region of cyclooxygenase 2 genetic (COX2) with the genetic susceptibility of lung cancer and its interaction with smoking.
METHODSTotally, 956 lung cancer patients recruited between January 2000 and December 2008 at Cancer Hospital, Chinese Academy of Medical Science as the case group, and 994 frequency-matched controls were randomly selected from a pool of cancer-free subjects recruited from a nutritional survey. All subjects were ethnic Han Chinese. There was no sex, age restrictions. Case group and control group were matched. Informed consent was obtained and 2 ml peripheral blood was collected from each subject. All samples were genotyped by polymerase chain reaction-restriction fragment length polymorphism method, smoking status of the subjects was surveyed.While the OR and 95% CI were estimated by logistic regression to evaluate the relation of COX2 -1195G > A variant and the risk of lung cancer.
RESULTSThe genetic allele COX2 -1195AA of control group and case group were 24.9% (247/994) and 28.3% (271/956) . Case-control analysis showed an increased risk of developing lung cancer for -1195AA genotype carriers (OR = 1.36, 95% CI: 1.03-1.79), compared with -1195GG carriers. When stratified by smoking status, the significant increased risk of lung cancer was found among smokers with COX2-1195AA genotype, with the OR (95%CI) was 1.56 (1.08-2.25); while among non-smokers, difference of lung cancer risk was not found among different genotypes (OR = 1.17; 95%CI: 0.77-1.61). Among heavy smokers (pack-year >20), -1195AA and -1195AG genotype carriers have significant increased risk of lung cancer with 1.85 (1.16-2.95) and 1.62(1.08-2.43) of OR (95%CI), respectively; among light smokers (pack-year ≤ 20), the OR (95%CI) of lung cancer risk in -1195AG and -1195AA genotype carriers were 0.78 (0.47-1.30) and 1.08 (0.60-1.94), respectively.
CONCLUSIONGenetic polymorphism in the promoter of COX2 gene interacting with smoking factor plays an important role in the development of lung cancer.

OBJECTIVETo observe the clinical effect and mechanism of migraine treated with pine needle moxibustion.
METHODSForty-three patients were randomly divided into 2 groups of pine needle moxibustion group (group A, 21 cases) and medicated thread moxibustion of Zhuang medicine group (group B, 22 cases). Same acu-points were selected as the main points for both groups, namely Fengchi (GB 20), Baihui (GV 20), Taiyang (EX-HN 5), Shuaigu (GB 8), Cuanzhu (BL 2), Sizhukong (TE 23), Yanglingquan (GB 34), Waiguan (TE 5) and Ashi points. Pine needle moxibustion was applied for the group A. Processed lighted pine needles were banded together with one even head to do moxibustion on acupoints or pain points. While, lighted medicated thread was adopted for the group B to do moxibustion. Therapeutic effects, the content of high-sensitivity C-reactive protein (hs-CRP), Mg2+ in the serum and the degree of pain of the two groups were compared.
RESULTS(1) In the group A, the complete remission rate was 47.6% (10/21) and the effective rate was 90.5% (19/21). In the group B, the complete remission rate was 13.6% (3/22) and the effective rate was 50.0% (11/22). The two rates in the group A were superior to those in the group B (both P < 0.01); (2) In the group A, the content of hs-CRP was decreased from (4.29 +/- 0.98) mg/L to (2.11 +/- 0.87) mg/L, and Mg2+ was increased from (0.67 +/- 0.28) mmol/L to (1.07 +/- 0.16) mmol/L. In the group B, the contents of the above mentioned indices were respectively decreased from (4.30 +/- 1.07) mg/L to (3.38 +/- 1.15) mg/L and increased from (0.68 +/- 0.21) mmol/L to (0.88 +/- 0.25) mmol/L. There were significant differences between the two groups after treatment (both P < 0.05). (3) The degree of pain in the group A after treatment was much lower than that in the group B (P < 0.05).
CONCLUSIONThe clinical effect of migraine treated with pine needle moxibustion is better than that with the medicated thread moxibustion of Zhuang medicine. And it has obvious regulation effect on the levels of hs-CRP and Mg2+ in the serum of patients.
