Objective To determine the monokine levels of serum and synovial fluid (SF) in patients with JSpAs and estimate the correlation between monokines and inflammatory indices.Methods Serum and SF monokines (IL 1?,IL 1?,IL 6,IL 8,IL 12 and TNF ?) were measured by sandwich ELISA in patients with JSpAs ( n =28) and healthy controls ( n =10).The correlation between serum monokines and inflammatory indeces and between both serum and SF monokine levels was analysed.Results Elevated serum level of IL 6 was found in patients with JSpAs as compared to healthy controls ( P

Objective To increase the preoperative diagnosis rate,reform the operation and improve the prognosis in children with ganglio -nauroma.Methods Clinical data of 20 children with ganglioneuroma hospitalized in Tongji hospital of Huazhong university of science and technology from Nov.1986 to May.2006 were reviewed(male 9,female 11).The biological,clinical and pathological characteristics of patients were analyzed.Results Among these 20 patients,15 cases were discovered to have no clinical symtom.The B ultrasound showed low-echo in all 16 cases.Under CT scan,20 cases showed low to moderate density shadows,and the distinct enhancement in these tumors was noted with enhanced CT scan.Fourteen cases undergoing MRI all showed low signals in T1W1 and inhomogeneous high signals in T2W1.All patients underwent surgical operations,completely removed in 14 cases,partly in 4 cases, and biopsy was performed only in 2 cases.Fifteen cases were followed up from 7 months to 6 years,tumor recurrence happened only in 1 case.Conclusions Ganglioneuroma is mostly found in chest-abdominal sympathetic chain,it grows up slowly and seems to be innocent.The imaging data of B ultrasound,CT and MRI can give helpful information in the diagnosis of ganglioneuroma.We shall pay attention to the choice of incision and avoidance of injuring the important blood vessels during the operation.Children who have neuroblastoma cells should receive prophylactic chemoprophylaxis treatment and the result of long-time follow up is satisfactory.

Objective To study the antitumor effect of toremifene on MCF7 cell lines,and investigate the role of mitogen-activated protein kinase pathway. Methods Inhibitory effect of toremifene alone or combined with MEK inhibitor PD98059 on MCF7 cells was measured by SRB test,and that on phosphorylated ERK was detected by Western blotting.Results Toremifene exhibited a concentration-dependent inhibitory effect on the activity of MCF7 cells.Phosphorylated ERK was significantly inhibited by 5,10 and 20 mmol/L toremifene.Combined with PD98059,toremifene had a significantly enhanced cytotoxity effect,which exceeded that of application alone. Conclusion Mitogen-activated protein kinase pathway may play an important role in the antitumor effect of toremifene which is independent of estrogens.Combined with PD98059,the antitumor effect of toremifene can be reinforced,indicating a synergistic effect of these two drugs.

The regulation mechanism of arecoline on rat hepatic CYP2E1 was studied in vivo. After oral administration of arecoline hydrobromide (AH; 4, 20 and 100 mg x kg(-1) x d(-1)) to rats for one week, the hepatic CYP2E1 mRNA level remained unchanged, but the hepatic CYP2E1 protein content was dose-dependently increased. Additionally, although the hepatic CYP2E1 activity was induced by AH treatment, the induction was attenuated with the increase in dosage. The results indicate that the effect of arecoline on rat hepaticdoes not involve transcriptional activation of the gene, but largely involves the stabilization of CYP2E1 protein against degradation or increased efficiency of CYP2E1 mRNA translation, and additionally involve the post- ranslational modification of CYP2E1 protein. Furthermore, the CYP2E1 response is fairly equal among the different species, the induction of rat hepatic CYP2E1 by arecoline suggests that there is a risk of metabolic interaction among the substrate drugs of CYP2E1 in betel-quid use human.

OBJECTIVETo explore methods and clinical effects of composite external fixtor in treating adult patients with unstable middle 1/3 of clavicular fractures.

METHODSFrom March 2008 to March 2011,36 patients with unstable middle 1/3 of clavicular fractures were treated with composite external fixtor. There were 24 males and 12 females, aged from 18 to 55 years old with an average of 43 years old. Twenty cases on the left side and 16 cases on the right side. Time from injury to operation was 2 to 6 days (averaged 3.5 days). According to Robinson classification, there were 7 cases with type 2A2, 18 cases with type 2B1, and 11 cases with type 2B2. No vessels and nerve damage occurred before opreation. The clinical effects were evaluated according to Neer scoring.

RESULTSAll cases were followed up from 6 to 12 months with an average of 8 months. The mean Neer score was 88.3 +/- 6.2, which included pain 31.6 +/- 3.2, functional score 25.7 +/- 2.2, range of motion score 21.1 +/- 1.7, and anatomy score 8.8 +/- 0.8. There were 22 cases in excellent, good in 13, fair in 1. Two cases occurred pin tract infection.

CONCLUSIONComposite external fixtor is an optional method in treating unstable middle 1/3 of clavicular fracture, and can obtain a good clinical effects.

OBJECTIVETo observe the effect of cold or hot properties of traditional Chinese medicines (TCM) on biological effect indexes, and analyze the contribution of variables on cold or hot properties, in order to preliminarily establish the discrimination mode for the biological effects of cold or hot properties.

METHODRats were randomly divided into the blank control group, cold TCM groups (Coptidis Rhizoma, Scutellariae Radix, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix and Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex and Evodiae Fructus), and orally administered with 10 mL x kg(-1) of corresponding TCM water decoctions for 30 d, twice a day. Altogether 53 biological effect indexes correlated to cold or hot properties of traditional Chinese medicines were founded by searching literatures. The data warehouse were established by using data-mining software Clementine12.0. Data of the blank control group, cold TCM groups (Coptidis Rhizoma, Phellodendri Cortex, Gardeniae Fructus, Sophorae Flavescentis Radix, Gentianae Radix) and hot TCM groups (Aconiti Lateralis Preparata Radix, Zingiberis Rhizoma, Alpiniae Officinarum Rhizoma, Zanthoxyli Pericarpium, Cinnamomi Cortex) were selected into a training set. C5.0 algorithm and C&R classification and regression algorithm were adopted to define the importance of variable, create the decision trees, and test hot or cold properties of Evodiae Fructus and Scutellariae Radix.

RESULTAccording to C&R classification and regression algorithm, SDH activity of livers was the most important hot or cold property, with the significance closed to 30%. It was followed by triglyceride, liver Na' -K' -ATPase enzyme, muscle glycogen and platelet distribution width, with the accuracy up to 97.39% in models. C5.0 algorithm showed that liver SDH activity was the most important hot or cold property, with the significance closed to 40%. It was followed by triglyceride, GOT, muscle glycogen and liver Na(+)-K(+)-ATPase enzyme, with the accuracy up to 98.26% in models. The possibilities that Evodiae Fructus is in hot property and Scutellariae Radix is in cold property were 100. 00% and 77.78% by using both C&R classification and regression algorithm and C5.0 algorithm.

CONCLUSIONThe SDH activity of liver is the most important biological effect index to distinguish cold and hot properties of TCMs. The discrimination pathway or mode of cold and hot properties is closely related to energy metabolism.
