This study was aimed to develop an ICP-MS method to determine contents of six types of heavy metals, which include Cr, Pb, Cd, As, Hg and Cu, in Pian-Zai-Huang Gan-Bao (PZHGB) tablets. The samples were pro-cessed by microwave digestion. And then, they were determined by ICP-MS. The results showed that the working curves of Cr, Cu, As, Cd, Hg and Pb had good linear relationships with the correlation coefficient which was more than 0.9993. The average recovery rate of Cr was 101.2%. The relative standard deviation (RSD) was 7.6%. The av-erage recovery rate of Cu was 96.4%, with the RSD of 3.5%. The average recovery rate of As was 101.3%, with the RSD of 1.8%. The average recovery rate of Cd was 100.2%, with the RSD of 0.3%. The average recovery rate of Hg was 100.5%, with the RSD of 4.2%. The average recovery rate of Pb was 104.2%, with the RSD of 5.6%. It was concluded that the method was stable and reliable, with high sensitivity and repeatability. This method can be used in the content determination of six types of heavy metals, which include Cr, Pb, Cd, As, Hg and Cu in PZHGB tablets.

BACKGROUND:Biological dressings with sealing negative pressure drainage can promote the healing of acute and chronic wounds. OBJECTIVE:To observe the clinical effects of biological dressings with sealing negative pressure drainage in repair of diabetic foot ulcer. METHODS: Totaly 40 patients with diabetic foot ulcer were enroled and al underwent debridement or debridement plus skin grafting treatment. Wound treatment methods were selected according to the wiling of patients. Patients in the test group (n=20) underwent polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage. Patients in the control group (n=20) underwent regular wound dressing treatment. At the 7th RESULTS AND CONCLUSION: The visual analog scale scores, blood sedimentation, C-reactive protein levels in the test group were lower than those in the control group (P < 0.05). The wound healing time in the test group was shorter than that in the control group (P < 0.05), and the patient satisfaction was higher in the test group than the control group (P < 0.05). There was no significant difference in economic costs between the two groups. There was no local or systemic toxicity, alergy and other adverse reactions in the test group. These results day of repair, visual analog scale scores, blood sedimentation, C-reactive protein levels, wound healing time, patient satisfaction and economic costs at the termination of the treatment in these two groups were compared. demonstrate that polyvinyl alcohol hydration algae salt bubble wound dressings with sealing negative pressure drainage in repair of diabetic foot ulcer is safe and effective to promote wound healing and reduce local inflammatory response.

Objective To study different e mbolization methods in various aneurys ms with metallic coils. Methods In 6 spherical aneurysms, the e mbolization was p erformed with coils in their bodies, discontinuing the total or part of the bloo d supply to the corresponding viscera. While in 6 diverticulum aneurysms, the em bolization with coils was conducted in their bodies only, maintaining the blood supply of the corresponding viscera. For some pseudoaneurysms, both afferent and efferent arteries were embolized and collateral arterial supplies were prevente d. Results All 19 cases 20 aneurysms, of aneurysms were success fully embolized. Among 8 cases of pseudoaneurysms, bleeding had been stopped in 7 cases. Putting coils in the b odies of aneurysms or embolizing both afferent and efferent arteries improved su ccessful rate. Conclusion Embolizing aneurysms with metallic co ils is an efficient, reliable, and simple interventional method for stopping bleeding.

Aim To investigate the protective effects and mechanism of aspirin against focal cerebral ischemia-reperfusion in rats. Methods Right middle cerebral artery was occluded by inserting a thread through internal carotid artery for 2 h, and then reperfused for 72 h. 60 mg?kg -1 dose of aspirin was intragastric administrated at 0 h and 6 h after reperfusion. The brain injured area, the mortality, and cerebral edema were estimated. The apoptotic cells of brain tissue were detected by terminal deoxynucleotidyl transferase mediated dUTP-biotin nick-end labeling (TUNEL) method. Bcl-2 and Bax were detected by immunohistochemical staining method. The activity of calcineurin (CaN) in brain tissue was determined by the inorganic phosphorus method. The content of adenosine 5′-triphosphate (ATP) in brain tissue was separated by capillary electrophoresis. Results By using of aspirin 60 mg?kg -1, all indications were dramatically improved. The injured area of brain [from (10.51?1.12)% to (0.94?0.08)%], the cerebral edema of occluded side [from (82.43?2.0)% to (76.29?0.77)%], and the mortality [from 28% to 0%] were dramatically reduced. In brain tissue of occluded side, 60 mg?kg -1 aspirin helped to reduce the number of apoptotic cells from (26.43?2.0) to (17.53?0.44), increase the ratio of Bcl-2/Bax from (0.61?0.05) to (1.01?0.15), inhibit the activity of CaN from (6.03?1.5) to (3.47?0.96), and improve the ATP level from (10.26?1.02) to (25.65?3.45). Conclusion The neuroprotective effects of aspirin on focal cerebral ischemia-reperfusion injury in rats for 72 h might be attributed to its effects by anti-apoptosis, increasing the ratio of Bcl-2/Bax, inhibiting the activity of CaN, and improving the energy metabolism.

Objective To investigate the effect of Salvia miltiorrhiza extracts on morphine physical dependence in mice. Methods The physical dependence model was induced by repeated sc morphine daily in mice and then withdrawal symptom was induced by ip naloxone. Different doses of S. miltiorrhiza extracts were administrated by ip during or after the induction phase of morphine dependence, and effects of S. miltiorrhiza extracts both by preventive and acute administration on naloxone-precipiated withdrawal symptom in mice were investigated. The potential physical dependence of S. miltiorrhiza extracts was studied. Results Compared to morphine model group, preventive administration of S. miltiorrhiza extracts (100—200 mg/kg) could reduce the number of naloxone-induced withdrawal jumps (P

Objective To investigate the effect of lipid soluble fraction in the radix of Salvia miltiorrhiza (FSM) on conditioned place preference (CPP) in mice induced by morphine and preliminarily identify the fraction in the radix of S. miltiorrhiza. MethodsMorphine or NS was sc injected every other day to induce the obvious CPP in mice for 6 d. Before 30 min of sc injecting morphine, mice were ip administered different doses of lipid soluble fraction in the radix of S. miltiorrhiza. RP-HPLC method was used to identify the major component in the lipid soluble fraction in the radix of S. miltiorrhiza. ResultsThe staying time in morphine-paired white compartment was significantly prolonged. After treatment with lipid soluble fraction in the radix of S. miltiorrhiza (40 mg/kg, ip), the staying time in morphine-paired white compartment was significantly shortened (P

AIM To study the protective effects of melatonin(MT) on acute cerebral ischemia reperfusion injury.METHODS The model of cerebral ishemia-2 h/reperfusion-24 h was induced by middle cerebral artery occlusion(MCAO) in SD rats. Melatonin (10,20 mg?kg -1 ip)was administered four times in an animal:At 0, 1, 2, 6 h of reperfusion. After 24 h reperfusion, the content of malondialdehyde(MDA),the activities of superoxide dismutase(SOD)and myeloperoxidase (MPO)in brain tissue, the content of thromboxane B 2(TXB 2) and 6-keto-prostaglandin F 1?(6-keto-PGF 1?)in plasma were measured. RESULTS Compared with vehicle group, MT 10, 20 mg?kg -1 protected the activity of SOD, reduced the content of MDA, MT 20 mg?kg -1 also inhibited the increase of MPO in brain tissue ,and attenuated the disequilibrium of TXB 2 /6-keto-PGF 1?.CONCLUSION The protective effects of MT on acute cerebral ischemia reperfusion injury may be related to its increasing antioxidase activities,decreasing lipid peroxidative damage and inhibiting inflammations.

AIM To investigate the effects of ondansetron, a selective 5 Hydroxytryptamine3 (5 HT 3) receptor antagonist, on morphine physical dependence. METHODS The morphine dependent models in mice and in isolated Guinea pig ileum were used. RESULTS Pretreatment of ondansetron for 12 days significantly reduced morphine withdrawal symptoms in mice ,such as body weight loss(Groups 2～100 ?g?kg -1 ?d -1 ) or reduced both body weight loss and jumping times (Group 100 ?g?kg -1 ?d -1 ). In addition, concomitant treatment with ondansetron(1～20 ?mol?L -1 ) dose dependently suppressed the contraction induced by naloxone in Guinea pig ileum. CONCLUSION The chronic pretreatment of ondansetron can prevent morphine physical dependence to some extent.
