OBJECTIVETo explore the clinical effect and mechanism of electroacupuncture at Jiaji (EX-B 2) on drug craving of heroin addicts.

METHODSOne hundred and twenty cases of heroin addicts were randomly divided into 4 groups, 30 cases in each. In acupuncture group 1, the Jiaji (EX-B 2) points of T5-T7 and Shenshu (BL 23) were selected with electroacupuncture; in acupuncture group 2, Neiguan (PC 6), Shenmen (HT 7) and Zusanli (ST 36) etc. were selected with electroacupuncture; in simulation group, Zusanli (ST 36) and Sanyinjiao (SP 6) were selected with analog electrical stimulation, and in blank group no any therapy was applied. The changes of drug craving were evaluated by Visual Analogue Scale (VAS) and the changes of beta-EP and Dyn-A in plasma before and after treatment were tested by radioimmunoassay.

RESULTSThe relapse rate of 77.3% (17/22) in acupuncture group 1 was lower than those of 88.5% (23/26) in acupuncture group 2, 90.5% (19/21) in simulation group and 95.7% (22/23) in blank group (all P < 0.05). At the 8th and 10th week of treatment, the VAS scores in acupuncture group 1 and 2 were much lower than those in blank group and simulation group (all P < 0.01); in which, it was lower in acupuncture group 1 than that in acupuncture group 2 (P < 0.05), and lower in simulation group than that in blank group. After 10 weeks of treatment, compared with the status before treatment, beta-EP and Dyn-A in plasma were increased in acupuncture group 1 and 2 (P < 0.05, P < 0.01), Dyn-A was decreased in both simulation and blank groups (both P < 0. 01) which was less obvious than those in both acupuncture groups (both P < 0.01) and superior in acupuncture group 1 than that in group 2 (P < 0.05).

CONCLUSIONElectroacupuncture at Jiaji (EX-B 2) can suppress the drug craving and reduce the relapse rate, and the mechanism may be related with the content of beta-EP, especially the increase of Dyn-A in plasma.

OBJECTIVETo investigate a method for quantitative differential diagnosis of damp-heat and cold-damp impeding syndrome of rheumatoid arthritis (RA) in Chinese medicine (CM).

METHODSLaboratory parameters were collected from 306 patients with RA. The clinical symptoms and laboratory parameters were compared between patients with these two syndromes (158 with RA of damp-heat impeding syndrome, and 148 with RA of cold-damp impeding syndrome), and a regression equation was established to facilitate discrimination of the two RA syndromes.

RESULTSThere were significant differences in disease activity score in 28 joints [DAS28 (4)], erythrocyte sedimentation rate (ESR), white blood cell count (WBC), C-reactive protein (CRP), platelet count (PLT), albumin (ALB) and globulin (GLB) between the two syndrome of RA (P<0.05). Logistic regression analysis showed that the parameters ESR, WBC, CRP, joint pyrexia, joint cold, thirst, sweating, aversion to wind and cold, and cold extremities were statistically useful to discriminate damp-heat from cold-damp impeding syndrome. The regression equation was as follows: P=1/{1+exp[-(3.0-0.021X (1)-0.196X (2)-0.163X (3)-1.559X (4)+1.504X (5)-0.927X (6)-1.039X (7)+1.070X (8)+1.330X (9))]}. The independent variables X (1)-X (9) were ESR, WBC, CRP, hot joint, cold joint, thirst, sweating, aversion to wind and cold, and cold limbs. A P value > 0.5 signified cold-damp impeding syndrome, and a P value < 0.5 signified damp-heat impeding syndrome. The accuracy was 90.2%.

CONCLUSIONThe regression equation may be useful for discriminating damp-heat from cold-damp impeding syndrome of RA.

BACKGROUNDHypertension often persists after adrenalectomy for primary aldosteronism (PA). Many studies have analyzed the outcomes of adrenalectomy for aldosterone-producing adenomas (APA) to identify predictive factors for persistent hypertension. However, differentially expressed genes in persistent postoperative hypertension remain unknown. Our aim was to describe gene expression profile of persistent postoperative hypertension patients with APA.

METHODSIn this study, we described and compared gene expression profiles in persistent postoperative hypertension and postoperative normotension in Chinese patients with APA using microarray analysis. Confirmation was performed with quantitative real time-polymerase chain reaction analysis. Bioinformatic analysis (gene ontology analysis, pathway analysis and network analysis) was used for further research.

RESULTSMicroarray analysis identified a total of 99 differentially expressed genes, including 18 up-regulated and 81 down-regulated genes. Among the dysregulated genes were fat atypical cadherin 1 as well as fatty acid binding protein 4 and other genes that have not been previously studied in persistent postoperative hypertension with APA. Bioinformatics analysis indicated that differentially expressed genes were associated with lipid metabolic process, metal ion binding, and cell differentiation. Pathway analysis determined that five pathways corresponded to the dysregulated transcripts. The mRNAs-ncRNAs co-expression network was composed of 49 network nodes and 72 connections between 18 coding genes and 31 noncoding genes.

CONCLUSIONSThis study revealed differentially expressed genes in persistent postoperative hypertension with APA and provided a resource of candidate genes for exploration of possible drug targets and prognostic markers.

OBJECTIVETo evaluate the long-term efficacy of microwave ablation in the treatment of small renal cell carcinoma (RCC).

METHODSWe retrospectively analyzed 140 cases of small cell renal carcinoma (151 lesions with a mean diameter of 2.8±0.8 cm) treated between April, 2006 and October, 2015 with ultrasound-guided microwave ablation with cooled-shaft needle antenna. One microwave ablation antenna was used for tumors less than 2 cm in diameter and 2 antennas were used for larger tumors. The patients received enhanced ultrasound and CT/MRI examinations at 1, 3, and 6 months after the operation and every 6 months thereafter. The overall survival, disease-free survival, and local tumor progression rate of the patients were evaluated.

RESULTSThe response rate of treatment (complete ablation at one month on enhanced images) was 100% in these patients. The local tumor progression rates at 1, 3, and 5 years were 0.9%, 2.0%, and 7.1%, respectively, and the 1-, 3-, and 5-year distant metastasis rates were 1.6%, 2.5%, and 7.9%, respectively. The overall survival rates of the patients at 1, 3, and 5 years were 98.4%, 94.8%, 89.5%, respectively, with disease-free survival rates of 98.4%, 93.0%, and 83.1%, respectively. No major complications occurred in these cases, and multivariate analysis showed that the tumor number (P=0.015) and tumor growth patterns (P=0.049) were independent risk factors that adversely affected the long-term outcome after surgery.

CONCLUSIONOur data show that microwave ablation is a safe and effective modality for treatment of renal cell carcinoma.

OBJECTIVETo evaluate the clinic information of coronary artery bypass grafting (CABG) combined with concomitant valve operation.

METHODSRetrospectively analyze the information of morbidity and mortality of 126 cases patients who underwent combined valve and bypass procedures between December 2000 and January 2005. These patients had been divided into 2 groups according to sex.

RESULTSThere were significant differences in the clinic characteristic such as weight and diabetes mellitus and mitral valve stenosis and three disease vessels of coronary artery between 2 groups (P < 0.05). The rate of the number of bypass grafts and morbidity and mortality of complication were significant differences (P < 0.05). The number of mitral valve replacement of female was more than that of male (P < 0.05). Five males died after operation, 1 case of heart failure, 1 case of high blood sugar, 2 cases of arrhythmia, 2 cases of organs failure; Seven females died after operation, one case of heart failure, one case of alimentary tract haemorrhage, three cases of arrhythmia, two cases of organs failure.

CONCLUSIONSCoronary artery bypass grafting (CABG) combined with concomitant valve operation is safe and effective. The rate of morbidity and mortality of complication of female is more than that of male. The study demonstrates that female gender is an independent risk factor for combined morbidity and mortality during and after combined valve and coronary bypass surgery. That is related to low weight and mitral valve stenosis of female.

OBJECTIVETo study the effect of polyamine biosynthesis inhibition on growth characteristics of human lung carcinoma cells and its correlation with the expression of human lung carcinoma associated antigen ALT-04ag gene.

METHODSThe gene expression was detected by RT-PCR and immunocytochemical tests. The cell growth characteristics were studied by cell growth curves, morphological observation, FCM analysis and DNA electrophoresis.

RESULTSHuman lung squamous carcinoma cells L78 treated with 5 mmol/L alpha-difluoromethylornithine (DFMO) for 5 days showed significant growth inhibition and apoptosis induction. The mRNA and protein expressions of ALT-04ag gene in the cells were downregulated, while these changes resulted from DFMO treatment were prevented by provision of DFMO along with exogenous putrescine.

CONCLUSIONThe effect of polyamine biosynthesis inhibition induced by DFMO restrains the growth characteristics and promotes apoptosis of human lung carcinoma L78 cells, which is associated with down regulation of ALT-04ag gene expression.

HCAP1 is a novel hepatic cancer related gene located on human chromosome 17p13.3. The loss of heterozygosity occurred at 17p13.3 in various human cancers. In order to investigate the effects of exogenous HCAP1 gene products on cell proliferation of T lymphoma Jurkat cell line, HCAP1 gene! was transfected into Jurkat cells mediated by liposome, and the cells stably expressing exogenous HCAP1 were screened with G418. The effects of HCAP1 products on cell proliferation were assessed by viable cell count, cell growth curve and colony formation assay in soft agar. The results showed that the HCAP1 transgenic Jurkat cells displayed slow growth rate, extended doubling time and reduced colony formation capability, as compared with the cells transfected with pBK/CMV empty vector (P < 0.01). It is concluded that exogenous HCAP1 gene products could inhibit the proliferation of Jurkat cells.
