In this paper, literature about adverse reaction induced by Puerarin injection published in recent years were reviewed and analyzed. It was reported that Puerarin injection can not only induce adverse reactions on multiple systems, such as immune, blood, urinary, digestive and cardiovascular system, but so far as to cause death. Therefore, it should be administered rationally and strictly according to the direction and the course of medication should be rigorously monitored to prevent the occurrence of adverse reactions.

Objective To study the tolerance to 188Re-1-hydroxy-1 ,1-ethylidene disodium phosphonate(HEDP) in patients with bone pain caused by osseous metastases. Methods Thirty-one patients(10with prostate cancer, 9 with breast cancer, 3 with lung cancer, 5 with liver cancer, 2 with rectal cancer, 1with esophageal cancer and 1 with renal cancer) received a single injection dose of 188Re-HEDP. The patients were divided into four groups according to the injection dose: 20 MBq/kg (6 patients), 30 MBq/kg(6 patients), 40 MBq/kg (9 patients), and 50 MBq/kg (10 patients). Haematological toxicity (WHO grading) of grade Ⅲ- Ⅳ was considered unacceptable. Vital signs and adverse effects after injection were recorded for 8 weeks. Blood counts were measured weekly during a period of 8 weeks. Biochemical parameters and electrocardiogram were assayed at week 4 and 8. Statistical analysis was performed for per-protocol (pp) population (t-test). Results Twenty-seven patients belonged to PP population with 5 in the group of 20 MBq/kg, 5 in the group of 30 MBq/kg, 8 in the group of 40 MBq/kg and 9 in the group of 50 MBq/kg.No obvious adverse effects and no significant change of vital signs, electrocardiogram, liver and renal function were found after injection. Alkaline phosphatase was slightly higher than baseline at week 4 and 8 after therapy, but the difference was not statistically significant. In the 20 MBq/kg group, reversible grade Ⅰ leucopenia was noted in 1 patient. In the 30 MBq/kg group, 2 patients showed reversible grade Ⅰ leucopenia including 1 alone with reversible grade Ⅲ thrombopenia. In the 40 MBq/kg group, reversible grade Ⅰ leucopenia and thrombopenia was observed in 1 patient and reversible grade Ⅱ leucopenia and thrombopenia in another patient. In the .50 MBq/kg group, 3 patients showed reversible grade Ⅱ leucopenia. The lowest level of thrombopenia was at week 4(143.5 × 109/L), leucopenia at week 6 (5.4 × 109/L) and anaemia at week 8(t = 3.1325, 3.3156, 3.4917, all P ＜ 0. 05 compared with baseline). At week 8, the mean level of platelet and leucocyte recovered to baseline. "Bounce pain" was found in 2 of 27 patients (7.41%).Conclusions The dose of 20 MBq/kg, 30 MBq/kg, 40 MBq/kg or 50 MBq/kg of 188Re-HEDP do not cause significant side effects on cancer patients with bone metastases, though there is a tendency that the haematological toxicity may increase as the dose of 188Re-HEDP increases.

AIM: To systematic review the effectiveness of refractive multifocal intraocular lens ( MIOL ) ReZOOM vs diffractive MIOL ReSTOR in the treatment of cataract.
METHODS: Randomized controlled trials comparing refractive MIOL ReZOOM with diffractive MIOL ReSTOR were identified by searching CENTRAL, MEDLINE, EMbase, WANFANG MED ONLINE, CMJD, SinoMed, and CNKI. Related journals also were hand-searched. Methodological quality of randomized controlled trials ( RCTs ) was evaluated by simple evaluate method that recommended by the Cochrane Collaboration. Data extracted by two reviewers with designed extraction form. RevMan software ( release 5. 2 ) was used for data management and analysis.
RESULTS:A total of 7 trials (846 eyes) were included for systematic review. Subgroup analyses were used according to different model comparison of ReSTOR MIOL. The results showed a significant difference in the mean of the best distance corrected intermediate visual acuity ( BDCIVA) in the ReZOOM MIOL group with WMD=-0.11, 95% CI (-0.16, -0.06) (P<0.0001). It showed a significantly difference in the mean of the uncorrected near visual acuity ( UCNVA ) , complete spectacle independent rate, halo rate and glare rate in the ReSTOR MIOL group with WMD= 0. 09, 95% CI (0. 05, 0. 14) (P<0-00001), WMD= 2. 62, 95%CI (1. 76, 3. 91) (P<0. 00001), WMD=1. 35, 95% CI (1. 15, 1. 60) (P=0. 0004) and WMD=1-29, 95% CI (1. 09, 1. 53) (P= 0. 003). There was no significant difference between the two groups in the mean of the uncorrected distance visual acuity ( UCDVA ) , the uncorrected intermediate visual acuity ( UCIVA) , the best corrected distance visual acuity ( BCDVA ) and the best distance corrected near visual acuity ( BDCNVA ) with WMD-0.03, 95% CI (-0.06, 0.01) (P=0.15), WMD= -0.04, 95% CI (-0. 09, 0. 01) (P=0. 10), WMD= -0. 01, 95%CI (-0. 04, 0-02) (P=0. 55) and WMD= 0. 06, 95% CI (-0. 06, 0. 17) (P=0. 32).
CONCLUSION: Patients implanted with ReZOOM MIOL can provide better BDCIVA; patients implanted with ReSTOR MIOL show better UCNVA, are less likely to appear light halo, glare and other visual adverse reactions; correction in spectacles cases, patients implanted with ReZOOM or ReSTOR MIOL have considerable performances in the far and near visual acuity.

Objective To compare the different effects of 1% diatrizoate meglumine,2.5% mannitol and water as oral contrasts in PET/CT scan in gastrointestinal tract delineation and 18F-fluorodeoxyglucose (FDG) uptake. Methods Sixty-one patients referred for PET/CT scan without gastrointestinal diseases were divided into three groups randomly ( random number method). One liter of 1% diatrizoate meglumine,2.5% mannitol,or water was orally taken by groups 1 (25 cases),2 (20 cases) and 3 ( 16 cases),respectively before scan. The scan was performed with GE Discovery LS PET/CT scanner in two-dimensional (2D) mode 50 min after 18F-FDG (5.55 MBq/kg) injection. Patients with abdominal lesions were excluded from this study. The degree of gastrointestinal filling and 18F-FDG uptake was evaluated by 3 nuclear medicine physicians using visual analysis according to a 4-grade classification method:none,mild,moderate,and high. Statistically analysis was performed by Kruskal-Wallis,Mann-Whitney and paired t tests.Results Both the differences of serum glucose and insulin levels were not significant before and after contrast taken in group 2. Group 2 had better gastrointestinal filling than that of group 1 and also better than group 3 except in rectum. The stomach,jejunum,ascending,and transverse colon were better filled in group 1 than in group 3. The degree of 18F-FDG uptake of group 3 was significantly higher than that of group 2 in stomach,jejunum and ileum (z= -3. 192,-3.290,-3.290,all P＜0.05),and was also significantly higher than that of group 1 (z = - 3. 603,P ＜ 0.05) in jejunum. The degree of 18 F-FDG uptake of group 3 was significantly lower than that of group 1 in ascending colon (z = - 2. 706,P ＜ 0. 05 ) and was significantly lower than that of group 1 and 2 in transverse and descending colon (z= - 3. 503,- 2.403,- 4.225,-4. 027,all P ＜0.05),and was also significantly lower than that of group 2 in rectum (z = -4. 128,P ＜0. 01 ). The maximum CT values in stomach,jejunum,ileum and ascending colon in group 1 were ( 132 ±23),(191 ±31),(313 ±47) and (374±53) HU,respectively,whose difference was significant (t = -7.088--1.781,all P ＜0. 01 ). Conclusion Oral iso-osmotic mannitol intake has better gastrointestinal filling and less physiological 18F-FDG uptake compared to diatrizoate meglumine and water.

To develop an analytic method for qualitative and quantitative analysis of dodecatetraenamides A, B in 42 samples of two official species of Asari Radix et Rhizoma( ARR) (37 samples of Asarum heterotropoides var. mandshuricum with different collection time and 5 samples of Asarum sieboldiivar. seoulense). The HPLC-IT-TOF-MS/MS methods for the qualitative and UPLC-PDA methods for the quantitative analysis were established. Dodecatetraenamides A, B were identified by comparing the retention time, UV absorption spectrum and quasi-molecular ion peak [ M + H]+ with the reference compound using HPLC-IT-TOF-MS/MS. The content of dodecatetraenamides A and B in ARR were determined by UPLC-PDA. The separation was successfully carried out on a ACQUITY UPLC BEH C18 (2.1 mm x 100 mm, 1.7 µm) column eluted with mobile phases of water (A) and acetonitrile (B) in gradient program (0-3 min, 35% B; 3-5 min, 35%-36% B; 5-6 min, 36%-43% B; 6 min-11 min 43% B; 11-12 min, 43%-100% B). The column temperature was 45 °C, and the detection wavelength was set at 254 nm. The flow rate was 0.6 mL · min(-1). On one level mass spectrometry scanning, the results showed that the quasi-molecular ion [M + H] + of both dodecatetraenamides A and B were m/z 248.20. The quantitative method with UPLC-PDA has made the baseline separation of the constituents, which were reported as mixtures in the most literatures. The average recovery of dodecatetraenamides A and B were 97.90% and 99.86%, the relative standard deviation were 0.4% and 1.1%, respectively. The contents of dodecatetraenamides A, B in all ARR samples was in the range of 0.11-3.89 and 0.24-6.65 mg · g(-1). Their contents reduced with the extension of storage time. Compared with the samples of 2013, the average content of the two constituents in the samples collected in year 2002-2003 reduced 34% and 36%, respectively (P < 0.05). Compared the A. sieboldii var. seoulense and A. heterotropoides var. mandshuricum with the same collective time and production area, the average contents of the two constituents in latter were up to (1.59 ± 0.75) mg · g(-1) and (2.90 ± 1.17) mg · g(-1), respectively, significantly higher than that in A. sieboldii var. seoulense (dodecatetraenamide A were (0.78 ± 0.52) mg · g(-1), dodecatetraenamide B were (1.69 ± 0.83) mg · g(-1)) (P < 0.05). The content of the dodecatetraenamide A in overground part was in the range of 0.11-0.33 mg · g(-1), dodecatetraenamide B was 0. 24-0.60 mg · g(-1), which were much lower than that of the underground part of ARR (dodecatetraenamide A was in the range of 0.73-3.89 mg · g(-1), dodecatetraenamide B was 2.11-6.24 mg · g(-1)). The method was certified to be simple, accurate and reliable and could be used for qualitative and quantitative analysis of dodecatetraenamide A and B in different species of ARR, also can be used for the comprehensive quality control of traditional Chinese medicine, Asari Radix et Rhizoma.

OBJECTIVETo investigate the expression dynamics and significance of matrix metalloproteinase-2 (MMP-2) membrane type-matrix metalloproteinase-2 (MT-MMP-2) in hepatic fibrosis and its reversal counterpart.

METHODSAn experimental CCl4 induced hepatic fibrosis rat model was established by intraperitoneal administration of carbon tetrachloride for 2, 4, 6, 8, 10 weeks, and normal rats were used as a control group. The immunohistochemical methods and in situ hybridization were used to detect MMP-2,MT-MMP-2 mRNA and related antigens in the liver.

RESULTSMMP-2,MT-MMP-2 mRNA and related antigens were expressed in mesenchymal cells and parts of hepatocytes besides active pathological changes, especially in the fibrous septum and portal area. Expression of MMP-2,MT-MMP-2 mRNA and related antigens were increased in hepatic fibrosis and decreased gradually in its reversal counterpart.

CONCLUSIONThis study suggested that mesenchymal cells are the main cellular origins of MMPs. The levels of MMP-2 and MT-MMP-2 antigens and gene expression were closely related to hepatic fibrosis. MMP-2 and MT-MMP-2 may play important roles in hepatic fibrosis and its reversal counterpart.

OBJECTIVETo explore the effects of the magnetic c-erbB-2 antisense probe of different concentrations on the morphology and expression of SK-Br-3 cancer cells in vitro.

METHODSBreast cancer SK-Br-3 cells were transfected for 24 h by antisense probe at an iron concentration of 5, 10, 25, 50, and 100 mg/L, respectively. The distribution and content of iron particles in SK-Br-3 cells was determined by Prussian blue staining, electron microscopy, and atomic absorption spectrometry. Cell viability was observed by trypan-blue exclusion and CCK-8 test. The protein expression of c-erbB-2 was assessed by the Western blot analysis. The changes of the signal strength were considered by magnetic resonance imaging (MRI).

RESULTSc-erbB-2 antisense probe was uptake by SK-Br-3 cells in a concentration-dependence manner within a certain range (5, 10, and the Medicine Scientific Research Project of Chongqing Health Bureau (062025)25 mg/L). When the probe concentration was 25 mg/L, iron content in cells was (18.38±0.28) pg, the cell vitality, survival, and c-erbB-2 protein expression were reduced significantly (all P<0.05), and the T2 value was lower significantly (P<0.05). However, the results of 50 mg/L or 100 mg/L group showed no significant difference with the 25 mg/L group (P>0.05).

CONCLUSIONThe magnetic c-erbB-2 antisense probe can effectively transfect and specifically inhibit the expression of SK-Br-3 cell lines at the iron concentration of 25 mg/L.
