1.Inhibitory effect of disodium cantharidinate on human hepatoma cell line HepG_2 and its molecular mechanisms
Journal of Chongqing Medical University 2007;0(11):-
Objective:To observe the inhibitory effect of disodium cantharidinate on human hepatoma cell line HepG2 and investi-gate its possible mechanisms. Methods:HepG2 cells were treated with different concentration of disodium cantharidinate,The in- hibiton of cell proliferation,cell cycle distribution,expression of Survivin and activity of Caspase-3 were respectively evaluated by MTT assay,flow cytometry,immunocytochemistry,and chromatometry. Results:Disodium cantharidinate could inhibit the proliferation of HepG2 cells. The IC50 at 24,48,72 h after intervention were 2.41?0.48,0.72?0.08,and 0.39?0.04 ug/ml,The cells of G2/M phase and activity of Caspase-3 were increased.the expression respectively of Survivin were inhibited after the intervention of disodium cantharidinate. Conclusion:The inhibitory effect of disodium cantharidinate on HepG2 cells may be mediated by the block of cellcycle,enhancement of Caspase-3,and inhibition of Survivin.
2.Clinical Study onYang Xin Huo XueNeedling Method plus Western Medication for Chronic Heart Failure Due to Coronary Heart Disease
Shanghai Journal of Acupuncture and Moxibustion 2017;36(6):676-678
Objective To observe the clinical efficacy of Yang Xin Huo Xue(nourishing the heart and activating blood flow) needling method plus Western medication in treating chronic heart failure due to coronary heart disease (CHD).Method Eighty patients with CHD-induced chronic heart failure were randomized into a treatment group and a control group, to respectively receiveYang Xin Huo Xueneedling method plus Western medicationor Western medication alone for intervention. The heart function was estimated and brain natriuretic peptide (BNP) was detected before and after the intervention in both groups, and the change of heart function was observed.Result Yang Xin Huo Xueneedling method plus Western medication achieved a satisfactory therapeutic efficacy in treating chronic heart failure, and its total effective rate was significantly different from the rate in the control group (P<0.05); compared with the control group, the BNP value declined more significantly in the treatment group, and the difference was statistically significant (P<0.05).Conclusion Yang Xin Huo Xueneedling method plus Western medication can produce a satisfactory efficacy in treating CHD-induced chronicheart failure.

A L-serine producing facuhative methylotroph mutant (Mth~H、Gly~R)was derived from Pseudomonas flava A3 by combination treatment with ultraviolet(UV)and diethylsulfate(DES).It could accumulate 6.2g/L L-serine in the medium containing 30g/L glycine and 1% methanol as carbon source when it was cultured for 3 days,and it has an improvement about 67.6% compared with the origin.The mutant also has a good stability of descendiblity of L-serine producing.
5.Effect of hydroxychloroquine on the expression of suppressors of cytokine signaling in MRL/lpr mice kidney
Chinese Journal of Rheumatology 2014;18(11):773-776
Objective To study the effect of hydroxychloroquine (HCQ) on the suppressors of cytokine signaling (SOCS) in the kidney of MRL/lpr mice and evaluate the protection of HCQ on lupus nephritis.Methods Twenty-six rats were randomly divided into 3 groups:the control group which was consisted of 6 mice; the MRL/lpr group which was consisted of 10 mice; and the HCQ group which was consisted of 10.24-hour urinary protein level and anti dsDNA levels were tested.The expressions of SOCS-1 and SOCS-3 protein were determined by western blot.Analysis of variance was used to determine statistically significant differences between the two groups.A P value less than 0.05 was considered to be statistically significant.Results Compared with the control group,the levels of 24-hour urinary protein [(2 356.6±509.3) mg vs (440.3±90.1)mg] and anti ds-DNA (128.7±32.3 vs 14.9±1.4) were significantly increased in the MRL/lpr group,the expression levels of SOCS-1 and SOCS-3 protein were increased.After treated with HCQ,the levels of 24-hour urinary protein [(70.8±11.1) mg vs (2 356.6±509.3) mg] and anti-dsDNA (111.8±330.1 vs 128.7±32.3)were significantly decreased,the expression level of SOCS-1 and SOCS-3 protein decreased significantly (P< 0.05).Conclusion HCQ can inhibit SOCS expression in the kidney of lupus mice,reduce proteinuria and delay progression of immune disorders and lupus nephritis.
6.Recent advances on treatment of primary central nervous system lymphoma
Journal of Leukemia & Lymphoma 2012;21(5):312-314
Primary CNS lymphoma (PCNSL) is a rare malignancy with peculiar clinical and biologic features,aggressive course,and unsatisfactory outcome.the particular microenvironment of this malignancy,and sanctuary sites where tumor cells grow undisturbed, strongly affects treatment efficacy. The execution of prospective trials is also difficult because of the rarity of the tumor and the impaired general condition and poor performance status of patients. Chemotherapy is indispensable for the treatment of PCNSL. High-dose methotrexate is the most effctive drug.PCNSL is sensitive to irradiation,but responses to radiotherapy alone are short-lived. MTX-based chemotherapy followed by whole-brain radiotherapy prolonged survival but is associated with delayed neurotoxicity especially in patients older than 60 years. A new approach is attempted to treat PCNSL with chemotherapy alone with defered radiotherapy in old patients with similar survival rencenfly. High-dose chemotherapy with autologous stem cell transplantation HDC/ASCT yielded promising results for recurent PCNSL.Clinical investigation with Temozolomide or rituximab have been reported.Further studies with these new drugs are needed.

8.Transcatheter treatment of postoperative pulmonary stenosis:current status and future perspectives
Chinese Journal of Applied Clinical Pediatrics 2014;29(10):725-727
Postoperative pulmonary artery stenosis is one of the popular complications.The disappointing results of surgical treatment for such lesions led to the introduction of interventional procedures (balloon angioplasty and stent implantation).Balloon angioplasty is applicable for branch pulmonary artery stenosis,however,balloon dilation alone rarely been effective in the long-term for these lesions.Since pulrmonary artery stenting was introduced in 1991,indications and use of stents for dealing with pulmonary artery stenosis have played a leading role in recent times.Intravascular stents are effective for stenotic artery dilation,can reduce right ventricle pressure and improve heart function.Excellent mid-and long-term results after stenting of postoperative pulmonary artery stenosis are demonstrated by numerous researches,with the new developments in stent design,indications for pulmonary artery stent implantation are likely to widen in the future.
9.Local recurrence of rectal carcinoma: diagnosis and treatment
International Journal of Surgery 2009;36(11):789-792
Rectal carcinoma is a common malignant tumor in China. Although it decreased greatly after the introduction of total mesorectal excision and preoperative radiotherapy, the local recurrence rate of rectal carcinoma after curative surgery is still up to 11.3%. Surgery is the most effective treatment for local recurrence of rectal carcinoma. If excised radically, the five-year survival of patients with rectal carcinoma could be more than 35%. Only a few patients will benefit from ex-tended radical surgery because of its extremely high postoperative morbidity and mortality. Strict selection of patients by mul-tiple preoperative examinations makes extended radical surgery more reasonable. For the unresectable advanced recurrent rectal carcinoma, multimodality palliative therapy could lead to symptom relief, elevated quality of life and prolonged surviv-al. We discuss the diagnosis and treatment of recurrent rectal carcinoma in this review.
10.Progress of colorectal neuroendocrine neoplasm
Journal of International Oncology 2011;38(9):693-696
Colorectal neuroendocrine neoplasm (NEN) is originated from colorectal neuroendocrine cells.The incidence of colorectal NEN is low,however it has been increasing in recent years.As the research work has gone further,WHO has graded colorectal NEN to neuroendocrine tumor,neuroendocrine carcinoma,mixed gland-neuroendocrine carcinoma and hyperplastic and pre-neoplastic lesions.Although colorectal NEN cells can produce hormones and have endocrine functions,the clinical symptoms may not be shown.The diagnosis and treatment for colorectal NEN are different according to different classifications and stages.
