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.

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 anti-tumor effect of adenovirus-mediated Bcl-XL shRNA on colon cancer cells in vitro.

METHODSA recombinant Bcl-xl adenovirus was constructed, amplified, and purified. The effect on mRNA expression of Bcl-XL was assessed by RT-PCR, and the effect on apoptosis-induction of colon cancer(Lovo cell line) in vitro was assessed by MTT assay and cell clonogenic assay.

RESULTSRT-PCR showed that Ad/Bcl-XL shRNA significantly down-regulated the mRNA expression of Bcl-XL in Lovo cells. Ad/Bcl-XL shRNA suppressed the proliferation of Lovo cells in a dose-dependent as well as a time-dependent manner compared with Ad/GFP (P<0.05). Treatment with Ad/Bcl-XL shRNA dramatically suppressed the colony formation of Lovo cells in a dose-dependent manner (P<0.05). Ad/Bcl-XL shRNA showed no effect on normal human fibroblast.

CONCLUSIONAd/Bcl-XL shRNA exhibits cytotoxic effect on Lovo cells and may have the potential value in the treatment of colon cancer.

It has been demonstrated that neural cell adhesion molecule (NCAM) is critical for the induction and maintenance of long term potentiation (LTP) in the CA1 region of rat hippocampus. In the present study, we investigated the changes in NCAM mRNA expression and NCAM protein level after the induction of LTP in vitro using the techniques of in situ hybridization and Western blot. The results showed that the number of NCAM mRNA positive labelled neurons significantly increased (76.6+/-11.5 neurons) 10 min after tetanus when the slope of fEPSP markedly increased. The level of NCAM protein also increased significantly (7.190+/-0.64 arbitrary unit/50 microg protein) 10 min after tetanus. The number of NCAM mRNA positive labelled neurons no longer changed (73.3+/-14.0) 1 h after tetanus, however, the NCAM protein level (9.031+/-0.71) at 1 h after tetanus was higher than that at 10 min after tetanus. Moreover, the NMDA receptor inhibitor AP-5, which blocked LTP, prevented the increase in NCAM mRNA expression and NCAM protein level. The results demonstrate that NCAM mRNA expression maintains a high level, whereas NCAM protein changes from a low level to a high level during induction and maintenance of LTP.

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 investigate the protective effect of six Kaixin San formulas on simulated cells model of depression, Alzheimer's disease and Parkinson's disease.

METHODThe in vitro simulated cells model of depression, Alzheimer's disease and Parkinson's disease was established by injuring SH-SY5Y cells with corticosterone (0.4 mmol x L(-1)) , injuring PC12 cells with neurotoxic amyloid peptide (Abeta25-35) (20 micromol x L(-1)) and injuring SH-SY5Y cells with 1-methyl-4-phenylpyridinium ion (MPP+) (250 micromol x L(-1)). The cell survival rate was assayed with MTT method and the degree of cell injury was detected with LDH.

RESULT100, 500 mg x L(-1) Dingzhixiao Wan prepared as mentioned in Beiji Qianjin Yaofang could significantly increase the survival ratio of SH-SY5Y cells injured by corticosterone and reduce LDH concentration released. All of the Kaixin San formulas could significantly increase the survival ratio of PC12 cells injured by Abeta25-35 and reduce LDH concentration released. Particularly, Kaixin San (10, 100, 500 mg L(-1)) prepared as mentioned in Beiji Qianjin Yaofang shown the best effect. And 500 mg x L(-1) Fushen Wan prepared as mentioned in Gujin Luyan could significantly increase survival ratio of SH-SY5Y cell injured by MPP and reduce LDH concentration released.

CONCLUSIONDingzhixiao Wan prepared as mentioned in Beiji Qianjin Yaofang could protect corticosterone-induced SH-SY5Ycells injury, showing a potential antidepressant effect. All of the six Kaixin San formulas could protect Abeta25-35-induced PC12 cells injury, but Kaixin San prepared as mentioned in Beiji Qianjin Yaofang shown the best potential effect for Alzheimer's disease. Fushen Wan prepared as mentioned in Gujin Luyan could protect MPP(+)-induced SH-SY5Y cells injury to some extent.

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.
