Objective To explore the relationship between acute organophosphate poisoning and atrial fibrillation (AF). Methods Three hundred and twenty-two acute organophosphorus poisoning of elderly patients treated from January 2000 to June 2008 in our hospital were analyzed. Among these patients, 36 cases with AF were selected as case group and 38 age-gender-matched cases without AF were selected as control group. Serum cholinesterase (ChE), myocardial damage markers such as creatine kinase (CK), creatine kinase-MB isoenzyme (CK-MB) and Troponin- Ⅰ (cTn-Ⅰ) were compared between the two groups. Results ChE was decreased in the two groups, and ChE was lower in case group than in control group [(1126. 42±1047.02) vs. (1604.82±934.06)U/L, t= 2.07, P=0. 0414]. CK, CK-MB and cTn-Ⅰ were increased in different degree in the two groups. There was no difference in CK between the two groups [(609.97±597.84) U/L vs. (462.84± 530. 71)U/L, t= 1. 121, P= 0. 266]. CK-MB and cTn-I were higher in case group than in control group [(97.31±104.50) vs. (55. 16±69.62)U/L, t=2. 052,P=0. 0438; (2.39±0. 88) vs. (1.81± 1.38) μg/L, t = 2. 132, P = 0. 036, respectively9 . Conclusions AF caused by acute organophosphate poisoning may be related to the decrease of ChE activity, acetylcholine accumulation and myocardial injury.

Objective: Astragalus mongholicus could promote angiogenesis.Microemulsion has been widely used in the researches of traditional Chinese medicine in recent years.This study aimed to investigate the effect of Astragalus mongholicus microemulsion modified-collagen on angiogenesis of rats in vivo.Methods: Fifty SD rats were randomly divided into 5 groups: blank collagen,blank microemulsion modified-collagen,vascular endothelial cell growth factor(VEGF) modified-collagen,Astragalus mongholicus microemulsion modified-collagen and Astragalus mongholicus microemulsion plus VEGF modified-collagen.Then four collagen samples were imbedded in each rat.After the establishment of the models,the rats were executed at 3,7 and 14 days.The weights of the collagen samples were measured,and their hematoglobin and hydroxyproline levels were determined by the hemiglobincyanide colorimetric and sampler alkaline hydrolysis methods.The color of the wound surface was observed and the surrounding tissues were examined by HE staining for those killed at 14 days.Results: Both Astragalus mongholicus microemulsion and Astragalus mongholicus microemulsion plus VEGF significantly increased the production of hematoglobin and hydroxyproline(P0.05).Conclusion: Astragalus mongholicus microemulsion might promote angiogenesis by increasing the number of micrangia and the production of hematoglobin and hydroxyproline.

Objective To evaluate the effect of a community-based nutrition education program on the dietary quality of the elderly with diet balance index(DBI). Methods Eighty-three volunteers from Zhujing Town of Jinshan District of Shanghai with age ≥60 years were served as study objectives,and a total of 70 people completed the program.They were given nutritional guidance bimonthly in combination with measures such as community publications,panel discussions and individual interviews.Measurements of dietary intakes,which lasted for 3 d, were performed before intervention and 12 months after intervention,respectively.Diet quality was evaluated with DBI scoring system,and the parameters were compared before and after intervention. Results There were significant differences in DBI-Total Score(DBI-TS),DBI-Lower Bound Score(DBI-LBS)and DBI-Diet Quality Distance(DBI-DQD)before and after intervention for these 70 people (P<0.05).The proportion of subjects with adequate milk and soy product consumption increased from 7.1% before intervention to 20.0% after intervention,that with proper amount of salt intake from 22.9%to 51.5%.and that with diverse diet from 20.0%to 49.9%.The major DBI pattern changed from pattern B (47.1%) and pattern E(34.3%)to pattern B (34.3%) and pattern A (32.9%). Conclusion The community-based nutrition education program for the elderly can improve the diet quality of the elderly.

Objective To explore methods of diagnostic and treatment for renal cortical abscess to reduce its misdiagnosis.Methods Eleven cases of renal cortical abscess diagnosed and treated at Beijing International Airport Hospital during 1991 to 2003 were reviewed and analyzed.Results Among the 11 patients with renal cortical abscess,diagnosis was established in nine(82%)before treatment,seven were cured by incision and drainage,one was cured by incision and drainage only after failure in percutaneous nephropuncture,and one was cured by intravenous injection of antibiotics.Two cases(18%)were misdiagnosed as renal cancer and radical nephrectomy were performed for them.Conclusions Diagnosis for renal cortical abscess should be based on combination of patients clinical manifestation,laboratory examinations and imaging findings.Incision and drainage is the choice of treatment for renal cortical abscess.

Objective To investigate the role of S100 calcium binding protein A12 (S100A12) in the pathogenesis of preeclampsia. Methods Sixty patients with preeclampsia were recruited from March 2013 to December 2013 in the First Affiliated Hospital of Zhengzhou University. Among them, thirty cases were defined as the mild preeclampsia group and thirty cases were defined as the severe preeclampsia group. The other thirty healthy pregnant women were recruited in the healthy pregnant women group. The levels of S100A12 protein in maternal peripheral blood were detected by enzyme-linked immunosorbent assay (ELISA). Immunohistochemistry of streptavidin peroxidase biotin (SP) method was used to measure the protein expression of S100A12. The trophoblast cells were cultured in vitro with plasma from the three groups, and a blank control group was set up as well. Transwell was used to detect the cytotrophoblast invasion ability. Western blot was used to measure the protein expression level of receptor for advanced glycation end products (RAGE). Results (1) The levels of S100A12 in maternal peripheral blood of patients with preeclampisa [mild group:(30.8 ± 2.7)μg/L, severe group:(49.3 ± 4.1)μg/L] were significantly higher than that of the control group [(15.8 ± 1.4) μg/L]. In addition, compared with the mild preeclampsia group, the level of S100A12 in the severe preeclampsia group was significantly higher (P<0.05). (2)Positive immunostaining of S100A12 was observed in the cytoplasm of cytotrophoblast, decidual cells and the placentas from the three groups. The positive rate in the mild preeclampisa group was 77%(23/30);in the severe preeclampsia group it was 93%(28/30);and in the healthy pregnant women group it was 23%(7/30). The positive rates of placenta in the mild and severe preeclampsia groups were significantly higher than that in the healthy pregnant women group (P<0.05). In addition, compared with the mild preeclampsia group, the positive rate of immunostaining of S100A12 in the severe group was significantly higher (P<0.05).(3) Cytotrophoblast invasion ability and the expression of RAGE in the mild preeclampsia group were 29.1±3.2 and 0.479 ± 0.038, respectively;in the severe preeclampsia group they were 16.8 ± 2.5 and 0.652 ± 0.059;in the healthy pregnant women group they were 38.6 ± 24.3 and 0.327 ± 0.024; and in the blank control group they were 42.6 ± 5.6 and 0.194 ± 0.011. Cytotrophoblast invasion ability and the expression of RAGE protein in the mild and severe preeclampsia groups were significantly higher than those in the healthy pregnant women group and the control group(P<0.05). Conclusions The expression of S100A12 increased in materal peripheral blood and placenta, and the receptor protein of S100A12 RAGE also had high expression. It suggested that the S100A12 may have some effect on the pathogenesis of preeclampsia.

Objective To investigate ultrasonography imaging feature of intravenous leiomyomatosis (IVL).Methods Analysing 34 cases of IVL retrospectively,which had been treated and diagnosed in the hospital from Jan,1998 to Dec,2003.Results Among 34 cases,2 cases were diagnosed as IVL,20 cases were diagnosed as uterine leiomyoma or uterine leiomyoma with degeneration and 12 cases as uterine leiomyoma with adenomyosis.Conclusions Knowledge shortage on the clinical feature of IVL causes the low rate of accurate diagnosis of IVL by ultrasonography imaging.
