Berbamine ( Ber. ) is a bis-benzyl-isoquinoline alkaloid isolated from the traditional Chinese medical herb, Berberis poiretis, and has Vide pharmacological effects. Clinical studies have demonstrated that Ber. had an effect of ingreasing the number of leukocytes in various leukocytopenia. But, up till now it has not been reported that Ber. take effect on enzymic metablism of inner cell and isoenzyme in the process of increasing leukocyte. The experiment observed the mice dynamic change of LDH in leukocyte and LDH isoenzyme of serum by cytochemistry and plane polyacrylamide gel electrophoresis tech-nigue. The result indicates that LDH enzyme reaction of granulocyte have increased in Ber. group and intensity of enzyme reaction has a positive interralation with the time of administrations. All specimen show 5 zones after LDH isoenzyme pattern analyse. The proportion of LDH-5 was changed and LDH-5 sub-band was detected in control and combination group. The experiment indicated that Ber. can affeet enzymic metablism of inner cell in the process of increasing leukocyte. There was simultaneously with a change in ratio of LDH isoenzyme pattern.

Objective To study the impact of postoperative aerobic exercise on the cardiac function of breast cancer patients during anthracyclines-based chemotherapy. Methods Sixty cases of female breast cancer pa-tients, from June 2014 to December 2015 for anthracyclines-based chemotherapy, were randomly divided into ex-perimental group (n = 30) and control group (n = 30). Four cycles of conventional anthracyclines-based chemotherapy were conducted in control group, while three times of aerobic exercise per week were added in exper-imental group until the end of treatment course apart from conventional treatment. The peak oxygen consumption (VO2max) and maximum heart rate (HRmax) were measured before and after chemotherapy in both groups, ac-companied by ECG monitoring and blood collecting to measure the changes in their N-terminal pro-brain natriuretic peptide (NT-proBNP), serum creatinine (SCr) and kinase isoenzyme (CK-MB). Results No significant differ-ences in various indicators before chemotherapy were reported between two groups (P>0.05). After chemotherapy, VO2 max/kg [(21.9 ± 3.6) vs. (14.5 ± 2.8) mL/(min·kg)], VO2 max [(1 523 ± 186) vs. (911 ± 185) mL/min] and HRmax[(115 ± 15) vs. (129 ± 16) beats/min] in experimental group were significantly improved when com-pared with those in control group; significant differences in hematological levels and ECG changes were also ob-served between two groups. Conclusion Aerobic exercise during chemotherapy can mitigate the cardiotoxicity of anthracyclines to patients, which provides a new idea and therapy to reduce the incidence of clinical cardiovascular events induced by anthracyclines-based chemotherapy.

OBJECTIVE To investigate the reasons and preventive measures of recurrent laryngeal nerve injury during operation in patients with benign thyroid neoplasm. METHODS The clinical data of 2243 cases with benign thyroid neoplasm were reviewed. The relations among different neoplasm regions, different procedures and injury of recurrent laryngeal nerve were analyzed. RESULTS Injury incidence of recurrent laryngeal nerve in this study was 3.0 %. In cases with nodular goiter on the dorsum of thyroid and recurrent laryngeal nerve exposed during operation, injury incidence of recurrent laryngeal nerve was 1.0 %. And there was no recurrent laryngeal nerve injury in cases with nodular goiter on other region of the thyroid. In cases used locality protection during operation, injury incidence of recurrent laryngeal nerve was 7.6 % when benign lesions on the dorsum of thyroid and was 0.17 % when benign lesions on other region of the thyroid. CONCLUSION In cases with nodular goiter or adenoma on the dorsum of thyroid, exposing recurrent laryngeal nerve is necessary during operation and in cases with benign lesions on other region of thyroid, locality protection is useful. There are three major routes for recurrent laryngeal nerve exposure.

BACKGROUND: Telomerase can maintain the telomere length and avoid cel replicative senescence and apoptosis in somatic cells. Its catalytic subunit cal ed telomerase reverse transcriptase has roles in mediating cellsurvival and anti-apoptotic functions. OBJECTIVE: To evaluate the effects of human telomerase reverse transcriptase on amyloid β1-40-induced human embryonic cortical neurons injury. METHODS: Human cortical neurons derived from 12-16 weeks old aborted fetuses were transfected with recombinant adenovirus vector encoding human telomerase reverse transcriptase. Expression of human telomerase reverse transcriptase was evaluated by immunocytochemical staining. Telomerase activity was measured using a PCR-based telomeric repeat amplification protocol enzyme-linked immunosorbent assay kit. Human embryonic cortical neurons were treated with 10 μmol/L ol/L amyloid β1-40 after transfected for 3 days. Cel viability, reactive oxygen species levels and glutathione contents in human embryonic cortical neurons were respectively detected by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, fluorescent probe 2',7'-dichlorodihydrofluorescein diacetate and chromatometry. RESULTS AND CONCLUSION: Expression of human telomerase reverse transcriptase reached peak at 3 days after transfection, and the telomerase activity was rebuilt; 10 μmol/L amyloid β1-40 could significantly reduce the cel viability of neurons and glutathione content (P < 0.05 and P < 0.01), and increase the reactive oxygen species levels (P < 0.05). The neurons transfected with human telomerase reverse transcriptase gene could be significantly against the toxicity of amyloid β1-40 and increase the cel viability and glutathione content (P < 0.05 and P < 0.01), and decrease the reactive oxygen species levels (P < 0.05). The results indicate that human telomerase reverse transcriptase can protect amyloid β1-40-induced human embryonic cortical neurons injury
