Objective To investigate the difference of effect between interventional treatments and intravenous therapy of lidamycin on VX2 rabbit liver cancer.Methods VX2 Carcinoma cells were surgically implanted into the left liver lobe of 12 New Zealand white rabbits to establish the VX2 rabbit liver tumor model.Tumor size was detected by type-B ultrasonic diagnostic instrument.The rabbits were randomly divided into two groups of six,respectively treated with the hepatic inter-ventional administration of lidamycin (LDM)(1 ml,0.05 mg/kg)under the guidance of digital subtraction angiography (DSA)(group A)and with the auricular intravenous administration of LDMat the same dose (group B).All the rabbits were sacrificed and anatomized on day 10 after treatment,whose liver tumor was fixed with 4% paraformaldehyde solution and embedded in paraffin.Proliferating cell nuclear antigen (PCNA)and CD34 expression in the sample sections of tumor tissue were assessed through immunohistochemical staining.The levels of alanine transaminase (ALT)and aspartate trans-aminase(AST)were detected by Cobas 8000.Finally,the inhibition of VX2 tumor was evaluated.Results The VX2 tumor volumes were all increased at 10 day after LDMtreatment.However,the tumors in group A were smaller than those of group B (P <0.05).The results of immunohistochemistry showed that the intervention therapy of LDM could further lower the expression of CD34 and PCNA compared to group B.Conclusion Hepatic interventional administration of LDM under the guidance of DSA produces a better effect on attenuating the tumor growth than the intravenous administration of LDM.

Objective To investigate the effects of melatonin (MT) on rats with acute paraquat (PQ) poisoning. Method Fifty-four Sprague-Dawley (SD) rats were randomly divided into three groups (each group 18 rats) and given the following treatment: intragastric injection of PQ at 50 mg/kg (PQ); intragastric injection of paraquat followed by intraperitoneal injection of MT at 10mg/kg once a day (MT); intragastric injection of normal saline (Control). Serum assays for malondialdehyde (MDA) levels and superoxide dismutase (SOD) and glu tathione peroxidase (GSH-Px) activities were determined on the 1st, 3rd and 7th day post treatment. Clinical manifestations of poisoning and pathological changes in the lungs were also observed. Results Serum MDA levels were significantly increased (P ＜ 0.01), and SOD and GSH-Px activities significantly decreased (P ＜ 0.05) in the PQ group compared to the control group. Serum MDA levels were significantly decreased, and serum SOD and GSH-Px activities increased in MT group compared to the PQ group (P ＜ 0.05). Clinical manifestations of intoxication and pathological lung changes were also ameliorated in poisoned rats treated with MT. Condutions Administration of MT alleviates clinical manifestations of acute paraquat poisoning in rats by Limiting the damage from lipid peroxidation.

This paper systematically analyzed the ancient monographs of acupuncture and moxibustion and comprehensive medical books from pre-Qin to 1911， and extracted the data according to the etiology and pathogenesis， treatment principles and methods， acupoint selection， needling and moxibustion， and taboos of needling and moxibustion. The pathogenesis of migraine in ancient books and documents is summarized as "the causes are diverse， and phlegm-dampness is the majority". For treatment， the features include "needling has a sequence， and the root and the branch should be treated separately" and "focusing on tonifying deficiency and drain excess". It is also obtained of the rich ideas of acupoints selection， extensive application records of moxibustion， unique application of bloodletting therapy and clear explanation of acupuncture and moxibustion taboos. All mentioned above is expected to enrich the ideas and methods of modern migraine treatment and improve the clinical effects.
