Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.

Objective To study the characteristics of event-related potentials P300 in patients with anxiety disorder(AD). Methods P300 tests were carried out in 30 patients with AD and 30 healthy adult controls. ResultsPatients with AD had significantly delayed P3 latency ([326?16] ms vs [339?19]ms, P

OBJECTIVETo observe the effect of tetrandrine on reversion of mice S180's obtained multi-drug resistance tumor cell induced by chemotherapy by PFC. And then discuss the molecular mechanism of it for the use of TCM in clinic to restrain the drug-resistant of chemotherapy, thereby improve the curative effect.

METHODBy the methods of less dosage of chemotherapy PFC, give the mouse cisplatin 3 mg x kg(-1) i.p., once a week; CTX and 5-FU 3 mg x kg(-1) i.g. four weeks, set up the mice models of multi-drug resistance of S180 tumor cell, and then observe the P170, Fas, CD54 and apoposis by flow cytometry.

RESULTTetrandrine can obviously lower the express of P170 increase the express of Fas and the apoposis of drug resistant tumor cell. And at the same time it can obviously reduce the express of intercellular adhesion molecule (CD54).

CONCLUSIONTerandrine, with its adjustment of correlated biotic active matter, can intervene the occurrence of the multi-drug resistance of tumor cells induced by chemotherapy.

This paper summarized the Chinese literatures in the previous 5 years about the pre-clinical animal researches on the application of electro-acupuncture (EA) treatment for depression, searched in China National Knowledge Infrastructure (CNKI). The efficiency of EA treatment for depression and the mechanism of it were discussed, to shed light on new ideas and new fronts for the further research on depression in clinical or pre-clinical fields.

OBJECTIVETo investigate the expression dynamics and significance of matrix metalloproteinase-2 (MMP-2) membrane type-matrix metalloproteinase-2 (MT-MMP-2) in hepatic fibrosis and its reversal counterpart.

METHODSAn experimental CCl4 induced hepatic fibrosis rat model was established by intraperitoneal administration of carbon tetrachloride for 2, 4, 6, 8, 10 weeks, and normal rats were used as a control group. The immunohistochemical methods and in situ hybridization were used to detect MMP-2,MT-MMP-2 mRNA and related antigens in the liver.

RESULTSMMP-2,MT-MMP-2 mRNA and related antigens were expressed in mesenchymal cells and parts of hepatocytes besides active pathological changes, especially in the fibrous septum and portal area. Expression of MMP-2,MT-MMP-2 mRNA and related antigens were increased in hepatic fibrosis and decreased gradually in its reversal counterpart.

CONCLUSIONThis study suggested that mesenchymal cells are the main cellular origins of MMPs. The levels of MMP-2 and MT-MMP-2 antigens and gene expression were closely related to hepatic fibrosis. MMP-2 and MT-MMP-2 may play important roles in hepatic fibrosis and its reversal counterpart.

This study was aimed to investigate the efficiency of modified methylation-specific polymerase chain reaction i.e. nested methylation-specific polymerase chain reaction, used to detect the promoter methylation of p16 gene in six hematological malignant cell lines, and to explore the application in selection of hematological malignant cell lines with promoter hypermethylation, and make them to be an idel cell models for studying the relationship between gene methylation and expression. DNAs were denatured by NaOH and then were subjected to bisulfite modification and a nested-MSP was used to amplify the promoter region, nested MSP product of p16 gene promoter was analyzed and sequenced. The results showed that the hypermethylation of p16 gene was detected in CA46 and U266, however, Molt4, K562, HL-60 and Jurkat cell lines were unmethylated. In conclusion, p16 gene methylation in hematological malignant cell lines can be perfectly detected by nested-MSP method, which is simple, sensitive and specific for screening all kinds of hematological malignant cell lines with p16 gene methylated.

OBJECTIVETo investigate the chromosomal aberration in sporadic colorectal carcinoma and its association with clinicopathological features.

METHODSComparative genomic hybridization(CGH) was used to screen the changes in the number of DNA sequence copies in 40 sporadic colorectal cancer patients in order to identify regions that contain genes important for the development and progression of colorectal cancer.

RESULTSIn 40 sporadic colorectal cancer, frequent gain at 20 q, 12 q, 13 q, 7 p, 7 q and 16 q were found, while loss was also found at 18 q, 5 q, 4 q, 8 pand 17 p. The number of chromosomal aberration was closely associated with tumor stage(P<0.05). No significant association was found between the number of chromosomal aberration and tumor site, histopathologic type and histologic grade.

CONCLUSIONSChromosomal aberration exists generally in sporadic colorectal carcinoma. The number of chromosomal aberration and gain of 20q are closely associated with tumor stage.

OBJECTIVETo evaluate the feasibility and stability of chemically conjugating IgM on collagen films.

METHODSIgM was labeled with 125I using the chloramine-T method. Six collagen films were randomly divided into two groups. In chemical coupling group 125I-labeled IgM was chemically coupled with the films through N-succinmiclyl-3- (2-pyridyl-dithio) propionate reaction. In control group 125I-labeled IgM was absorbed onto collagen films. The amount of IgM on the collagen films and the amount of IgM remained on the films after extensive rinsing with phosphate buffered saline were monitored by counting the radioactivity of 125I.

RESULTSThe amount of antibodies loaded onto collagen films in the chemical coupling group was 15 times higher than that on the control films, showing significant statistical difference (P < 0.01). And the stability of conjugation antibodies on collagen films was significantly better than the control films.

CONCLUSIONChemical coupling is an effective approach to immobilize antibodies on collagen for further plasmid DNA tethering.

OBJECTIVETo determine the effects of Chinese herbal monomers such as baicalin, berberine, and matrine on the androgen receptor (AR) mRNA expression in SZ95 sebocytes in vitro and to explore the possible mechanism of using traditional Chinese medicines to treat acne.

METHODSSZ95 sebocytes were cultured and then treated with berberine, baicalin, matrine, and 13-cis-retinoic acid for 24 hours. Reverse transcription polymerase chain reaction was applied to detect the changes of AR.

RESULTAR mRNA was downregulated by 13-cis-retinoic acid of 1 x 10(-5) mol/L and 1 x 10(-6) mol/L, and by baicalin of 1 x 10(-4) mol/L (P < 0.05).

CONCLUSION13-cis-retinoic acid and baicalin may exert antiandrogenitic action by inhibiting AR mRNA expression in human sebocytes.
