ABSTRACT
Puerarin injection is commonly used in clinical treatment of coronary heart disease, angina pectoris, retinal artery, vein occlusion, sudden deafness and so on. This paper is aimed to evaluate the safety of puerarin injection in clinical use and explore the related factors that may cause its adverse reactions (ADRs), so as to find the warning signal of safety medication in time, put forward early warning, make early judgment and treatment, and ensure the safety of drug use. By strengthening surveillance, the best medication plan was established to prevent the occurrence of adverse reactions of puerarin injection and enhance people's awareness on the safety of puerarin injection. Database were searched to collect literature related to ADRs of puerarin injection. The data were extracted and analyzed by decision tree with treeage software and ² test was used to verify the data. A total of 62 papers involving 129 cases were included. The results showed that ADRs occurred mostly in patients aged 50-79 years, with the immune system and blood system accounting for the majority (88.3%), and ADRs occurred mostly 48 h after drug administration (61.1%). The severity of ADRs was not related to the dosage of puerarin, but it was related to the choice of the infusion solvent. In puerarin injection, most of the ADRs were moderate or severe (64.3%), 13 out of 129 cases were of death. Therefore, the indications and methods of use should be strictly controlled, and the allergic history of patients should be carefully questioned before medication to strengthen the monitoring of drug use.

OBJECTIVE@#To observe the effects of blocking and activating chloride channels on hemolysis induced by puerarin injection in rabbits and to investigate the roles of chloride channels in hemolytic reaction induced by puerarin injection.@*METHODS@#Rabbit erythrocyte suspension was incubated with different concentrations of puerarin injection(0.75, 1.5, 3, 6, 12 mg/ml) at 37C for 6 hours. The cell imaging system was employed to observe whether puerarin injection induced hemolysis. The hemolysis rate was detected by microplate reader and flow cytometry. Effects of activating and closing chloride channels on the hemolysis induced by puerarin injection were explored.@*RESULTS@#Puerarin injection could induce the hemolysis of rabbit erythrocytes . In the range of 1.5 mg/ml~12 mg/ml, puerarin injection could induce hemolysis in a concentration-dependent manner (=3, <0.01). The chloride channel blockers tamoxifen (20 μmol/L) and ATP (10 mmol/L) significantly inhibited the hemolysis induced by puerarin injection (=3~5, <0.01). Application of low concentration ATP (50 μmol/L) to activate the chloride channel significantly increased puerarin injection induced hemolysis (=4, <0.01).@*CONCLUSIONS@#The hemolytic effect of puerarin injection is dose-dependent , and the activation of chloride channel is closely related to the hemolysis induced by puerarin injection.

OBJECTIVE:To explore therapeutic efficacy and safety of Puerarin injection for elderly female patients with osteo-porosis and unstable angina pectoris,and its effects on serum inflammatory factors. METHODS:Totally 107 elderly women with osteoporosis and unstable angina were analyzed retrospectively and divided into control group(53 cases)and observation group(54 cases) according to drug use. Control group was given routine treatment as Caltrate D,Alendronate sodium tablet,Glyceryl trini-trate tablet ,Metoprolol tartrate tablet,Atorvastatin calcium tablet,Trimetazidine hydrochloride tablet. On the basis of control group, observation group was additionally given Puerarin injection 4 mL added into 5% Glucose injection 500 mL intravenously,once a day. Treatment course of 2 groups lasted for 2 weeks. Therapeutic efficacies of 2 groups were observed as well as the levels of se-rum inflammatory factors(hs-CRP,TNF-α,MMP-9,sCD40L),and the occurrence of ADR. RESULTS:The total response rates of angina pectoris and osteoporosis pain in observation group were significantly higher than control group,with statistical signifi-cance (P0.05). After treatment,the levels of hs-CRP,TNF-α,MMP-9 and sCD40L in 2 groups were significantly lower than before,and the observation group was significantly lower than the control group,with statistical sig-nificance(P<0.05). No obvious ADR was found in 2 groups during treatment. CONCLUSIONS:Based on routine treatment,Pu-erarin injection shows significant therapeutic efficacy for senile female osteoporosis patients with unstable angina and can significant-ly reduce the levels of serum inflammatory factors with good safety.

ABSTRACT
ObjectiveTo explore the curative effects of Puerarin Injection associated with Irbesartan on decompensated chronic cor pulmonale heart failure. MethodsA total of 168 cases conforming to the diagnostic standards were randomized into control group (92 cases) and therapy group (76 cases). In the control group: Based on the results of sputum and X-ray, broad-spectrum antibiotics were firstly selected and used for 3 days after admission. Then sensitive antibiotics were selected according to the results of sputum culture and drug sensitivity test. Medicine for relieving cough and asthma, and apophlegmatisant were used routinely. Patients with heart failure were treated with Digoxin or diuresis. In addition to the above treatments, the therapeutic group were treated with Puerarin Injection 600mg and Irbesartan 75mg once a day. The two groups were both treated for 20 days. Results①The incipient slope, 0.8 slope, 0.5 slope and the minimal surplus were all significantly changed (P＜0.01) in therapeutic group after the treatment. There were significant difference in the incipient slope, 0.8 slope, 0.5 slope and the minimal surplus before and after treatment both in the control group and therapeutic group. ②The plasma viscosity and blood viscosity decreased observably (P＜0.01) after the treatment in the therapeutic group, and more obviously than that in the control group (P＜0.01). ③The arterial oxygen pressure (PaO2) and arterial oxygen saturation (SaO2) in the therapeutic group were enhanced more prominently than that of the control group (P＜0.01). ④The mean pulmonary arterial pressure (mPAP) and pulmonary vascular resistance (PVR) decreased obviously in the therapeutic group after the treatment, and more observably than those in the control group (P＜0.01). ⑤The cardiac output and cardiac index were improved prominently in the therapeutic group after the treatment, and more obviously than that of the control group (P＜0.01). ⑥The heart functional capacity (NYHA) improved significantly after the treatment both in the control group and the therapeutic group (P＜0.05). ConclusionsPuerarin Injection and Irbesartan could remarkablely change the erytlu'ocyte deformabifity, improve the hemorheology, lower pulmonary hypertension, and improve the cardiac function and the clinical efficacy in decompensation stage.
ABSTRACT
[ Objective ] To observe the therapeutic effect of acupuncture on cleft acupoints combined with puerarin intervention for the treatment of prolapse of lumbar intervertebral disc with blood stasis. [ Methods ] Sixty cases were divided into two groups by using random number: group A (n = 30) was treated by acupuncturing the Jiaji points from 4th lumbar vertebrae to 1st sacral vertebrae and specific points such as Waiqiu (GB36), Weizhong (BL40) and Xiaxi (GB43), and with intervention of puerarin Injection into the region of affected lumbar intervertebral foramen; group B (n = 30) was treated by acupuncturing the same acupoints as group A and with routine acupoint injection of puerarin Injection. After a 30-day treatment , the therapeutic effect in the two groups was evaluated by symptoms and signs scoring and pain visual stimulation scoring method. Peripheral blood interleukin 6 (IL-6) and blood rheology parameters before and after treatment were also observed to investigate the therapeutic mechanism. [Results] After one treatment course, the therapeutic effect in group A was better than that in group B (Z = 2.525, P = 0.012) and the mean treatment course was shorter (P 0.05). [Conclusion] The synergistic action of acupuncture combined with puerarin intervention for the treatment of prolapse of lumbar intervertebral disc with blood stasis is better than that of routine acupoint injection of puerarin Injection. The mechanism may be related to the fact that intervention treatment can introduce the drug to the affected area, which benefits the improvement of peripheral blood IL-6 and blood rheology parameters, and thus relieve radiculitis.
ABSTRACT
OBJECTIVE:To probe into the regular pattern,related factors and prognosis of hemolytic reactions induced by Puerarin injection.METHODS:A total of 44 hemolytic cases induced by Puerarin injection reported in 26 papers of domestic journals published since 1994 were analyzed.RESULTS:Of the 44 cases collected,31 were males and 13 females,with a mean age of(67.5?9.6) years.The hemolytic reactions were induced either by Puerarin injection or Puerarin for injection with a mean dose of(445.2?123.8)mg and a mean concentration of puerarin(in infusion) of(1.55?0.52) mg?mL~(-1).The hemolytic reactions occurred chiefly after administration of puerarin for 7 consecutive days(7.96?3.84 days on average) and appeared as acute hemolytic anemia.The puerarin specific antibody was noted in immunological test.10 patients including 9 males and 1 male died at a mean age of(72.1?5.7) years.CONCLUSION:The occurrence and turnover of Puerarin Injection - induced hemolytic reactions are related to many factors,to which great attention should be paid.
