Objective To investigate the diagnostic value of serum soluble transferrin receptor(sTfR) in children with iron deficiency anemia(IDA).Methods Sixty-three children with microcytic hypochromic anemia were divided into IDA and non-IDA(n-IDA)groups,on which sTfR and other iron metabolism related indexes such as serum ferritin(SF) and serum iron(SI) were measured,and(t-test) between groups and analysis of ROC curve were carried out.Results The mean concentration of sTfR in the group of IDA was above normal value and t-test difference was extremely significant compared with n-IDA group(P

Objective To investigate the expression of human macrophage metalloelastase(HME) both in gastric cancer cell lines and gastric cancer tissues,and to find the role of HME in gastric carcino genesis.Methods Fifty eight patients who were operated in our hospital during April to Aug.2003 were enrolled.The samples taken from cancer,paracancer or normal tissues of these patients and cancer cell lines(MGC-803,SGC-7901,AGS)were detected for HME protein and HME mRNA expressions by Western blot and immunohistochemistry,RT-PCR and fluorescence quantitative PCR,respectively. Results Both HME mRNA and HME protein expressions were found in all three gastric cancer cell lines.The expressions of HME mRNA and HME protein in gastric cancer tissues was increased signifi- cantly compared with that in normal tissues(P0.05).Conclusions The increased HME expression in gastric cancer tissures compared with normal tissue indicate that HME may be a potential tumor marker for gastric cancer.

Objective To evaluate the effect of nitrous oxide(N2O) on the cuff pressure of ProSeal laryngeal mask airway(PLMA) in pediatric anesthesia. Methods Thirty-two pediatic patients were enrolled and divided into two groups randomly.PLMA cuffs were inflated with air(Group A) or 50% N2O/oxyen(Group N) to 20 mmHg as initial pressure.The intracuff pressure was monitored during anesthesia with 50% N2O in oxygen. Results Intracuff pressure increased to(40.6?9.3) mmHg in Group A and slightly decreased in Group N.Deflation volume in Group A was much more than that in Group N[(4.4?2.3) mL vs(2.6?1.0) mL,P

Inhibitors of kinesin spindle protein (KSP) are a promising class of anticancer agents that cause mitotic arrest and induce apoptosis of tumor cells. A series of novel tetrahydro-beta-carboline derivatives were synthesized as kinesin spindle protein inhibitor and evaluated as potential antitumor agents. All compounds showed promising KSP inhibitiory activity. Compounds 8 and 9 exhibited better antitumor activity (Lung/A549, Stomach/AGS) than CK0106023 with GI50/IC50 values (1.07/1.62 and 1.46/3.27 micromol x L(-1), 1.09/>10 and 1.22/6.33 micromol x L(-1), respectively).

Objective To investigate the daily total fluoride intake in relating to the prevalence of skeletal fluorosis in two villages in Jiangsu Province,in order to provide the scientific evidences for the control and prevention of endemic fluorosis.Methods Adults sampled from a high-fluoride Village,Wamiao,and a low-fluoride Village,Xinhuai,were surveyed in this study according to the fluoride concentration in their household shallow well.The average daily total fluoride intake from difierent sources and the skeletal fluorosis were investigated in each subject.Then the subjects from two villages were allocated into five subgroups(＜2.00,2.00～,3.00～,4.00～,≥5.00 mg/d),the relation fluoride intake and prevalence of osteofluorosis was analyzed.Results The prevalence of skeletal fluorosis in Wamiao Village was 31.06%(41/132),but no skeletal fluorosis case(0/35)was found in Xinhuai Village.According to the daily total fluoride intake,subjects with higher daily total fluoride intake tended to associated with a higher prevalence of skeletal fluorosis in a significant dose-response relationship(regression equation:y=2.624-6.855x+3.424x2:r=0.997).The benchmark dose lower limitation of daily total fluoride intake with 95% confidencewas 2.50 mg/d calculated according to this dose-response relationship,the reference dose(RfD)was 2.50 mg/d.In Wamiao Village a significant difference was also found between daily total fluoride intake in 41 subjects[(5.09±1.20)mg/d]with X-ray detectable skeletal fluorosis and in 91 subjects[(3.08±1.12)mg/d]without X-ray detectable skeletal fluorosis(t=-9.32,P＜0.01).Conclusions These findings indicate that the daily total fluoride intake has a significant dose-response relationship with the prevalence of skeletal fluorosis in an endemic fluorosis area associated with high-fluoride drinking water;and the RfD in this study was lower than that in the national standard of"Chinese hygienic standard for daily total fluoride intake(WS/T 87-1996)"(3.50 mg/d).

OBJECTIVETo compare clinical effect of T-shaped locking internal fixation and external fixation in treating dorsal Barton's fracture,and investigate selective strategy of internal fixation.

METHODSFrom January 2008 to January 2013, 100 patients with dorsal Barton's fracture were randomly divided into two groups. In treatment group, there were 30 males and 20 females with an average age of (33.8±3.6) years old;30 cases were type B, 20 cases were type C;and treated with T-shaped locking internal fixation. In control group, there were 32 male and 18 females with an average age of (32.9±3.4) years old; 29 cases were type B, 21 cases were type C; and treated with external fixation. Volar tilt, ulnar deviation and radial height at 3 months after operation were detected and compared between two groups. Mechara functional evaluation were used to evaluate postoperative clinical effects. Clinical cure time, postoperative complications,joint mobility and function score were recorded and compared between two groups.

RESULTSIn treatment group,volar tilt was (11.9±2.7)°, ulnar deviation was (20.8+ 2.9)°,and radial height was (10.9±1.8) mm; while volar tilt was (9.1±1.6)°, ulnar deviation was (17.1±2.9)°, and radial height was (8.1±1.5) mm in control group. Treatment group was better than control group in volar tilt, ulnar deviation and radial height. Clinical cure time in treatment group was(12.0±2.3) weeks, shorter than control group (18.0±4.1) weeks. The incidence of complications in treatment group was lower than control group. According to Mehara functional evaluation,20 cases got excellent results, 25 good, 3 moderate and 2 poor in treatment group; 16 cases got excellent results, 14 good, 10 moderate and 10 poor in control group. Treatment group was better than control group in clinical effects.

CONCLUSIONT-shaped locking internal fixation with postoperative functional exercise for the treatment of dorsal Barton's fracture fits for biomechanics demands,and has advantages of stable fixation,rapid recovery, less complications and good functional recovery, it has better clinical effects.

The safety of drugs has been the important issue that has caught the mutual attention of clinicians and patients. Kidney is one of the important organs in drug metabolism. The study is based on hospital information system (HIS) data from 20 nationwide general hospitals, indicated by Scr and BUN. Generalized boosted models (GBM) based on propensity score method were used to balance confounding factors. The study contrasts changes on renal function between used Shuxuening injection patients and the unused to explore whether Shuxuening injection affects renal function in clinical. The results showed that Shuxuening injection is likely to affect Scr in logistic regression (P value is 0.035); after the logistic regression based on propensity score method (P value became 0.513, 0.590), no differences were found between the two groups; before and after the logistic regression based on propensity score method (P value was less than 0.05), Shuxuening injection possibly affects BUN. Nevertheless, this study is a retrospective analysis. Logistic regression based on propensity score method can control the known confounding factors very well, while there may be the unknown ones. Therefore, the further exploration is required to monitor whether Shuxuening injection affects really BUN, which will provide clinical guidance for Shuxuening injection safe application.
