Objective To investigate the clinical value of bone scintigraphy for the diagnosis of synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome. Methods The characteristics of SAPHO syndrome on 99Tcm-MDP imaging of 8 cases were retrospectively analyzed. Results The 99TcmMDP bone scan was positive for all patients. Seven cases were found lesions in the costoclavicular region, 3cases involved with unilateral sacroiliac joint, 2 cases involved with spine and 1 patient with extremity. Four lesions were found without relevant clinical symptoms. Conclusion Bone scintigraphy is useful for the diagnosis of SAPHO syndrome, especially for those lesions with no clinical symptoms.

Objective To use the AU2700 biochemical analyzer to evaluate the performance of the reagent kit for determining se-rum glycated albumin(GA)by the enzymatic method.Methods On the basis of the relevant documents of CLSI-EP,the perform-ance evaluation of the Lucica GA-L reagent kit for detecting GA was performed on the precision,accuracy,linearity range and refer-ence range;the correlation between the results detected by the two kinds of reagent kit (enzymatic method)was analyzed.Results The reagent had high precision(CV<3%);the dilution had good linearity;the average recovery rate of GA was 97.7%,the average recovery rate of albumin(ALB)was 96.43%;the detection results by the two kinds of reagent kit had good correlation (r2 =0.976, P <0.01).Conclusion The Lucica GA-L reagent kit shows the good analytical performance on the AU2700 biochemical analyzer, which is consistent to the manufacturers statement and can be better used in clinic.

Objective To evaluate the effect of Rab23 on the proliferation of a squamous cell carcinoma cell line Sa3,and to investigate its mechanisms.Methods Cultured Sa3 cells were classified into four groups:normal control group transfected with green fluorescent protein (GFP),Rab23-overexpressing group transfected with a GFP-labelled Rab23-overexpressing plasmid,Rab23-silencing group transfected with a plasmid carrying a Rab23-targeting shRNA,empty vector group transfected with an empty vector.After additional culture for different durations,plate colony formation assay and flow cytometry were performed to evaluate the proliferative activity of Sa3 cells,and Western blot was conducted to detect the expression of Erl/phosphorylated-Erk in Sa3 cells.Statistical analysis was carried out by t test,one-way analysis of variance and Bonferroni's multiple comparison test.Results Stable Sa3 cell lines with overexpression or silencing of Rab23 were established by plasmid construction and lentivirus-mediated transfection.The plate colony formation assay showed that the colony formation rate was significantly lower in the Rab23-overexpressing group than in the normal control group (2.3％ ± 0.2％ vs.3.6％ ± 0.3％,P ＜ 0.05),but higher in the Rab23-silencing group than in the empty vector group (4.1％ ± 0.2％ vs.1.8％ ± 0.03％,P ＜ 0.01).Rab23 overexpression induced G1 phase arrest in Sa3 cells.The proliferation index was significantly decreased in the Rab23-overexpressing group compared with the normal control group (0.581 ± 0.035 vs.0.698 ± 0.018,P ＜ 0.05),but increased in the Rab23-silencing group compared with the empty vector group (0.567 ± 0.015 vs.0.444 ± 0.014,P ＜ 0.01).As Western blot showed,there were no significant changes in the expression of Erk in the Rab23-silencing or-overexpressing group compared with the normal control group,whereas the expression of p-Erk was attenuated in the Rab23-overexpressing group compared with the normal control group,but enhanced in the Rab23-silencing group compared with the empty vector group.Conclusions Rab23 could inhibit the proliferation of Sa3 cells,which may be associated with the Erk pathway.

Xanthii Fructus is a traditional medicine for the treatment of nasal diseases in clinic, mainly come from the burs of Xanthium sibiricum with a worldwide distribution. By sorting and studying literature of Chinese medicine and comparing different figures recorded with the morphological description of several species from Xanthium (Asteraceae) in the Flora of China, combining the biological investigation in resource survey, the article pointed out that the burs or the whole herbs of X. mongolicum, as well as X. sibiricum, has been used by the traditional Chinese medicine in ancient time. It provides a reference for further studies in the future.

Objective To analyze the clinical presentation and maternal-neonatal outcome of HELLP syndrome.Methods 32 cases with HELLP syndrome from January 2003 to January 2009 were analyzed retrospectively.Results The incidence of HELLP syndrome in preeclampsia was 3.7%.Complete HELLP were 17 cases,partial HELLP were 15 cases.Two pregnant women died(one case of intracranial hemorrhage,one case of acute left cardiac failure),the mortality was 6.3%.Five newborns died,the mortality was 15.6%.The main materal complications were DIC(8 cases),placental abruption(2 cases),intracranial hemorrhage(2 cases).The main perinatal complications were preterm labor(20 cases),newborn asphysia(17 cases),SGA(15 cases).Conclusion HELLP syndrome is one of the most serious obstetric complications,early diagnosis,early therapy,controlling hypertension and termination of pregnancy in time are most important for treatment.

OBJECTIVETo explore the effect of Shenxiong Huayu Capsule (SHC) on the cerebral ischemia-reperfusion (IR) injury and the expression of growth associated protein 43 (GAP43) after total cerebral IR in the hippocampal CA1 region of rats.

METHODSTotally 100 male adult SD rats were randomly divided into five groups, i.e., the control group, the model group, the group A (by taking SHC once daily), the group B (by taking SHC twice daily), and the group C (by taking SHC thrice daily), 20 in each group. The total IR model was prepared by improved Pulsinelli's 4-vessel occlusion method. Morphological changes of the hippocampal CA1 region were observed by HE staining at day 1, 3, 7, and 14. The expression of GAP43 in the hippocampal CA1 region was detected using immunohistochemical assay at day 1, 3, 7, and 14. Meanwhile, the behavioral score was determined. The expression of GAP43 in the hippocampal CA1 region was detected using Western blot at day 14.

RESULTSCompared with the control group, the expression of GAP43 increased in the model group, the behavioral score was elevated, degenerated neurons increased, and survival neurons decreased in the model group (all P < 0.05). Compared with the model group, the expression of GAP-43 increased (with the most significant difference seen in the group C, P < 0.01), the behavioral score significantly decreased, degenerated neurons decreased, and survival neurons increased in each HSC group (all P < 0.05). Survival neurons obviously increased at day 14, of which, most number of survival neurons and highest contents of GAP43 protein could be seen in the group C, showing statistical difference when compared with those of the group A and the group B (P < 0.01).

CONCLUSIONSHC had protective effect on total cerebral IR in the hippocampal CA1, which might be associated with increased expression of GAP43.
