The academic thoughts of Lingnan acupuncture and moxibustion have been an essential part of Lingnan medicine. By exploration and arrangement of Lingnan medicine and books, journals and literatures regarding acupuncture and moxibustion, the ancient and modern acupuncturists and their academic contributions in Lingnan area were reviewed. As a result, the number of Lingnan acupuncturists and their works was low before Qing Dynasty, while from the Republic of China era to People's Republic of China, a considerable amount of acupuncturists emerged with quite a lot of works. By exploration and arrangement of Lingnan acupuncturists and their works and academic opinion, the acupuncture-moxibustion school characterized by Lingnan could be formed and developed.

OBJECTIVETo introduce a new technique for the treatment of helical keloid.

METHODSThe procedure consisted of two steps. In the first step, a kidney-shaped expander of 50 ml was placed subcutaneously in the retroauricular area. Routine inflation with normal saline followed. In the second step, about two months afterwards, the expander was taken out and the helical keloid was excised. The expanded flap was advanced to cover the wound.

RESULTSThe operation has been performed on 12 patients of 16 sites of helical keloid since 2000. Postoperative follow-up from 3 months to 2 years revealed satisfactory results. The reconstructed ear maintained a good contour.

CONCLUSIONThe technique creates a retroauricular flap rich in blood supply, which can be used to close the defect left by helical keloid excision. It provides a good treatment for the helical keloid replaced with normal skin from the mastoid region.

OBJECTIVETo investigate the correlation between expression of A-kinase anchoring protein 95 (AKAP95) and protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

METHODSFifty-one cases of lung cancer were included in the study. The protein expression of AKAP95, cyclin E1, and cyclin D1 were measured by immunohistochemistry.

RESULTSThe protein expression of cyclin E1 in lung cancer tissues was significantly higher than that in para-cancerous tissues (positive rate: 75.56%vs 20%, P < 0.01); its expression showed no relationship with histopathological type, lymph node metastasis, and cellular differentiation (P > 0.05). The protein expression of cyclin D1 in lung cancer tissues was higher than that in para-cancerous tissues (positive rate: 69.39% vs 14.29%); its expression showed a significant relationship with histopathological type (P < 0.05). The expression of AKAP95 was correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissues (P < 0.01).

CONCLUSIONCyclin E1 and cyclin D1 are highly expressed in lung cancer tissue, suggesting that they play an important role in the development and progression of lung cancer. The protein expression of cyclin E1 has no relationship with cellular differentiation, lymph node metastasis, and histopathological type of lung cancer, and the protein expression of cyclin D1 has a significant relationship with histopathological type. The expression of AKAP95 is correlated with the protein expression of cyclin E1 and cyclin D1 in lung cancer tissue.

OBJECTIVETo evaluate the therapeutic effects and adverse effects of transarterial oily chemoembolization combined with interstitial laser thermotherapy (TOCE+ILT) in the treatment of hepatocellular carcinoma.

METHODSTotally 120 patients with hepatocellular carcinoma were randomized into two groups and received interventions with TOCE+ILT or TOCE combined with percutaneous ethanol injection (TOCE+PEI). The treatment was repeated when necessary until the tumor was completely ablated, after which the therapeutic effects were evaluated and the patients were the followed up for observing long-term clinical outcome.

RESULTSOf the 120 patients enrolled in this observation, 105 were followed up for two years (54 in TOCE+ILT group and 51 in TOCE+PEI group). The complete tumor necrosis rate of TOCE+ILT group was significantly higher than that of the TOCE+PEI group (84.8% vs 73.9%,Chi(2)=4.405, P=0.036), and TOCE+ILT was associated with a significantly higher negative conversion rate of AFP positivity (77.8% vs 56.1%, Chi(2)=4.592, P=0.032). The 1-year survival rate were similar between two groups, but the 2-year survival rate was significantly higher in patients with TOCE+ILT (79.6% vs 60.8%, Chi(2)=4.477, P=0.034). The hepatic function was comparable between the two groups before treatment, and 1 week after treatment, the ALT level in patients undergoing TOCE+ILT was significantly lower than that in patients with TOCE+PEI (95.90-/+56.06 U/L vs 116.31-/+45.27 U/L, t=2.04, P=0.043). Post-embolization syndrome was observed in the patients in two groups, but no severe adverse events were found.

CONCLUSIONTOCE+ILT has good therapeutic effects and mild side effects in the treatment of hepatocellular carcinoma.

OBJECTIVETo construct a pcDNA3.1-AML1-ETO expression vector and investigate its effects on proliferation and differentiation of U937 leukemic cells.

METHODSAML1-ETO gene was amplified by PCR from pCMV5-AML1-ETO and inserted into eukaryotic expression plasmid pcDNA3.1/V5-His-TOPO. The recombinant plasmid was transfected into U937 cells by Lipofectamin 2000. Individual clones selected with G418 were isolated. The integration and the expression levels of AML1-ETO in transfectants were determined by PCR, RT-PCR and Western blot analysis respectively. Trypan blue refusal staining method was used to detect the proliferation of U937 cells. Light microscope was applied to observe the morphologic changes of the cell. The expression of myeloid cell differentiation antigen was detected using flow cytometry.

RESULTSThe recombinant pcDNA3.1-AML1-ETO was confirmed by enzyme digestion and sequencing. The highly expressing AML1-ETO subclone was established. AML1-ETO was expressed in U937 cells transfected with pcDNA3.1-AML1-ETO. The growth of the monoclonal cells was inhibited evidently (P < 0.05). The expression of CD11b in transfected group \[(4.17 ± 0.31)%\] was lower than that in empty plasmid transfected group and non-transfected group \[(11.40 ± 0.17)% and (11.03 ± 0.15)%\] respectively (P < 0.001). Transfected cells displayed morphology of less differentiation. The expression level of CDl1b was unchanged in transfected cells treated with TPA (P > 0.05).

CONCLUSIONThe eukaryotic expression vector for AML1-ETO gene was successfully constructed and expressed in U937. AML1-ETO inhibits the proliferation and differentiation of transfected cells. It provides the basis for further study of mechanisms of AML1-ETO in leukemogenesis.

OBJECTIVETo test the accuracy of real-time three-dimensional echocardiography (RT3DE) imaging system for evaluating left ventricular mass (LVM) in phantom and excised canine heart.

METHODSTen left ventricular (LV) wall phantoms made of two rubber-bursas, ten excised canine hearts underwent RT3DE and two-dimensional echocardiography (2DE). In RT3DE "full volume" imaging, the myocardial volume was measured using 2, 4, 8, and 16-plane method with the analysis software of RT3DE. Mass was then calculated by multiplying the resulting myocardial volume by specific density of myocardial tissue. In 2DE the masses were measured by area-length method. The true LV wall phantom mass was measured by water displacement and the canine LVM was weighed by anatomy, which served as a reference standard. We compared RT3DE or 2DE with true mass.

RESULTSIn LV wall phantoms, RT3DE correlated with true masses strongly (r = 0.813-0.994) and weakly correlated between 2DE and true masses (r = 0.628). In excised canine hearts, there is an excellent correlation between RT3DE and true masses (r = 0.764-0.991), while 2DE value showed a lesser correlation (r = 0.514). There are no difference between RT-3DE and true masses (P > 0.05) but different between 2DE and true masses (P < 0.05). In different planes, there was no difference between 8-plane and 16-plane (P > 0.05) but different between 8-plane and 2, 4-plane (P < 0.05).

CONCLUSIONRT3DE can accurately quantify LVM and provide a new tool to evaluate LV function. For LVM by RT3DE, 8-plane measurement method is the best choice for accuracy and convenience.
