[Objective]To compare curative effects of radial head resection with internal fixation in treatment of Mason type-Ⅱ、Ⅲ fracture of radial head.[Method]Forty-five patients with Mason type-Ⅱ、Ⅲ fracture of radial head were dividered into 2 groups(A and B).The patients in group A(n=23) were performed with radial head resection.The patients in group B(n=22) were performed with open reduction and internal fixation.The results of the two groups were assessed for statistical analysis on the following aspects: pain,motion,strength and X-ray finding.Broberg and Morrey criterion were used to compared curative effect of elbow function between the two groups.[Result]The patients in the two groups were followed up for a mean time of 8 years(group A) or 3 years(group B).The difference of the pain VAS score,mean flexion/extension of the elbow,Broberg and Morrey elbow scores,carrying angle and shift of radius between the two groups were with statistical significance(P0.05).[Conclusion]In comparing with the radial head resection,open reduction and internal fixation can obtain more satisfactory elbow motion,greater muscle strength and better joint function m the treatment of Mason type-Ⅱ、Ⅲ fracture of radial head.

Objective To compare the prognosis of ST elevation acute myocardial infarction(STEMI) of delayed emergency per‐cutaneous coronary intervention(PCI) and elective PCI following the thrombolysis with reteplase ,and to investigate the clinic value of the former solution .Methods One hundred and twenty STEMI patients were reviewed retrospectively and were divided into 2 groups according to PCI .Eighty two cases were divided into emergency group :thrombolysis with reteplase offered within 6h was followed by elective PCI;38 cases were divided into delayed group:PCI was done after 12-24 h after ATEMI′occurring .The clini‐cal features and CTG changes were recorded ,TIMI class of IRA was conducted before and after PCI ,and their prognosis were com‐pared .Results There was no statistical differences in the class of thrombolysis of myocardial infarction(Class 0 -1 ,2 -3) of in‐farction relative artery (IRA)(4 .88% ,95 .12% vs .5 .26% ,94 .74% ) after PCI(P>0 .05) .There was no statistical difference in LVEF ,LVEDVI and LVESVI 3 months after attack between two groups(P>0 .05) .There was statistical difference in the severe cardiac failure and malignancy arrhythmia between two groups(P<0 .05) ,while no statistical difference exist in angina after infarc‐tion as well as cardiac mortality after attack between two groups(P>0 .05) .Conclusion Delayed emergency PCI to remove the ob‐struction in the coronary artery has no significant difference with elective PCI following thrombolysis in the incidence of composite end point events in STEMI .

Objective To evaluate the effect of total alkaloids of Sophora alopecuroides L on the nervous behavior and the expression of neurotransmitters in rats. Methods 48 male SD rats were randomly divided into 4 groups:blank group,total alkaloids of Sophora alopecuroides L treatment with 4 mg·kg-1 ·d-1 ( low dose group) ,8 mg·kg-1 ·d-1( medium dose group) and 16 mg·kg-1 ·d-1( high dose group) groups. After successive intragastric administration for 30 days,the locomotor activity was applied to test the nervous behavior and emotional state of rats in each group. After behavioral tests were finished,the contents of trypto-phan (Trp),5-hydroxytryptophan (5-HTP),5-serotonin (5-HT),5-hydroxyindoleacetic acid (5-HIAA), norepinephrine (NE),epinephrine (E) and dopamine (DA) were detected by ELISA in serum and brain. Results In the experiment of locomotor activity,compared with blank group ((95.33±12.75) times),the numbers of horizontal movement of Sophora alopecuroides L in medium and high dose group ( ( 61. 64 ± 5.91),(64.62±5.79)times both P<0.05) were significantly reduced (P<0.05, P<0.01).Compared with the blank group ((4.33±0.66) times),the numbers of vertical motion of Sophora alopecuroides L in medium and high dose group ((3.05±0.09)times,(3.77±0.69)times) were significantly reduced (P<0.05, P<0.01). Compared with blank group ((2.25±0.39) number),the granule number in high dose group ((3.38±0.40) number) were significantly increased (P<0.05, P<0.01),and emotional stress degree increased. Meanwhile,compared with blank group,the content detection of 5-HT,5-HIAA in different dose groups of the total alkaloids of Sophora alopecuroides L was improved obviously(P<0.01),but there was no significant effect on the content of Trp,5-HTP,NE,E,DA(P>0.05). Correlation analysis indicated that the degree of au-tonomic activity in rats with the content of 5-HT,5-HIAA and DA in serum was negatively correlated (P<0.05, P<0.01) ,the degree of emotional stress and the content of 5-HT,5-HIAA in brain was negatively cor-related (P<0.05, P<0.01) . Conclusion The total alkaloids of Sophora alopecuroides L can reduce the ac-tivity of rats and increase the degree of emotional stress. And the mechanism may be correlated with the in-creasing level of 5-HT and 5-HIAA in serum and brain.

Objective To compare the clinical results of femoral head replacement for femoral in- tertrochanteric fractures and femoral neck fractures in aged patients.Methods Forty cases of femoral in- tertrochanteric fractures and 45 cases of femoral neck fractures (aged over 80 years) underwent femoral head re- placement from August 1996 to April 2002 in our department.The clinical results of the two groups were retro- spectively compared and analyzed statistically.Their follow-up periods,ranging from 3 to 7 years,averaged 4.6 years in the intertrochanteric fracture group and 5.5 years in the neck fracture group.Results The differences in time of hospitalization,perioperative blood loss,postoperative drainage,ambulation trine,early compiications be- tween the two groups were of no statistical significance (P＞0.05).The differences in operation time and inequality in leg length after operation between the two groups were of statistical significance (P＜0.05).The operation time was longer and more limb-length inequality occurred in the intertrochanteric fracture group than in the neck fracture group.There was no significant difference in Harris score at the last follow-up between the two groups.The X-ray at the final follow-up showed that there was insignificant difference in postoperative hip joint space,hip pain,or stem loosening between the two groups (P＞0.05).The stem revision incidences were of no statistical significance be- tween the two groups (P＞0.05).The two groups reported no acetabular protrusion.Conclusion With standard cemented prostheses,femoral head replacements can achieve as similar functional outcomes for patients with in- tertrochanteric fractures as for those with femoral neck fractures.

Abstract: Objective　In order to explore the application prospects of the phenyl pyrazole insecticide fipronil for mosquito control and identify potential target genes involved in the resistance of Aedes aegypti to fipronil, and lay the foundation for an in-depth study of the resistance mechanism of Aedes aegypti to fipronil. Methods　Using Aedes aegypti sensitive strains as experimental materials, Aedes aegypti larvae were treated with fipronil, and the differences in gene expression of Aedes aegypti larvae before and after drug administration were compared at the transcriptome level using transcriptome sequencing combined with bioinformatics analysis, and the differential genes were analyzed. Results　A total of 757 differentially expressed genes were identified between the fipronil-treated group and control group, including 217 and 540 up- and down-regulated genes, respectively. Among these, the expression of glutamate-gated chloride channel (GluCls) genes varied significantly before and after treatment. Gene ontology analysis revealed that differentially expressed genes were enriched in catalytic activity, binding, metabolic processes, and membrane-related functions, while KEGG pathway analysis indicated enrichment in biosynthesis, metabolism, and life regulation processes, while the glutathione metabolic pathway was enriched in 15 differentially expressed genes. Conclusions The transcriptome results revealed that GST gene expression was significantly upregulated in fipronil-treated Aedes aegypti larvae, indicating that GST gene is involved in the development of fipronil resistance in Aedes aegypti larvae. In addition, GluCls gene expression was also significantly different before and after treatment, suggesting that GluCls migh be a potential target receptor for fipronil resistance in Aedes aegypti. As GluCls is an ideal target receptor found only in invertebrates, this discovery provides a reference and basis for further exploration of the toxicological mechanism of fipronil on Aedes aegypti.

OBJECTIVETo investigate the best choice of operation opportunity and operation plan for limb fractures combined with severe craniocerebral trauma in children.

METHODSFrom January 2005 to July 2012,36 patients with limb fractures and severe craniocerebral trauma were received,including 24 males and 12 females aged from 1 to 13 years old (mean, 6.1 +/- 3.0). The time from injury to hospital was (18.0 +/- 15.0) h. Glasgow coma score were less than 8 with an average of 6.4 +/- 1.3. AIS-ISS score were 25.9 +/- 8.1. Thirteen patients were open fracture, 23 were closed fracture. Patients were divided into immediate operation group (21 patients) received fracture fixation with 24 h, the average time was (15.0 +/- 7.4) h, and delayed operation group (15 patients) received fracture fixation after 24 h, the average time was (165.4 +/- 114.6) h. All patients were treated by open reduction, and 33 cases by internal fixation, 3 cases were external fixation. Operative time, blood loss, fracture healing time and brain trauma,physical trauma, postoperative rehabilitation situation were observed and evaluated.

RESULTSAll patients were healed at stage I ,and no dead, aggravating of coma, disorders of breathing and circulation occurred during operation. Operative time,blood loss,healing time in immediate operation group was (44.5 +/- 25.3) min, (47.1 +/- 36.5) ml, (2.7 +/- 0.5) months, respectively; while in delayed operation group was (87.0 +/- 40.0) min, (112.7 +/- 67.5) ml, (3.8 +/- 1.2) months,respectively; and there were obvious differences between two groups. There was no siginificant meaning in Glasgow coma score and Fugl-Meyer motor function between immediate operation group (4.7 +/- 0.6, 97.9 +/- 2.7) and delayed operation group (4.7 +/- 0.5, 97.7 +/- 3.9) (t = 0.23, P > 0.05; t = 0.11, P > 0.05).

CONCLUSIONThe condition of limb fractures combined with severe craniocerebral trauma in children is seriously, comfortable surgical opportunity should according to particular case, and immediate operation can performed on the condition of stabled vital signs.

BACKGROUND/OBJECTIVES: D. candidum is a traditional Chinese food or medicine widely used in Asia. There has been little research into the anticancer effects of D. candidum, particularly the effects in colon cancer cells. The aim of this study was to investigate the anticancer effects of D. candidum in vitro and in vivo. MATERIALS/METHODS: The in vitro anti-cancer effects on HCT-116 colon cancer cells and in vivo anti-metastatic effects of DCME (Dendrobium canidum methanolic extract) were examined using the experimental methods of MTT assay, DAPI staining, flow cytometry analysis, RT-PCR, and Western blot analysis. RESULTS: At a concentration of 1.0 mg/mL, DCME inhibited the growth of HCT-116 cells by 84%, which was higher than at concentrations of 0.5 and 0.25 mg/mL. Chromatin condensation and formation of apoptotic bodies were observed in cancer cells cultured with DCME as well. In addition, DCME induced significant apoptosis in cancer cells by upregulation of Bax, caspase 9, and caspase 3, and downregulation of Bcl-2. Expression of genes commonly associated with inflammation, NF-kappaB, iNOS, and COX-2, was significantly downregulated by DCME. DCME also exerted an anti-metastasis effect on cancer cells as demonstrated by decreased expression of MMP genes and increased expression of TIMPs, which was confirmed by the inhibition of induced tumor metastasis in colon 26-M3.1 cells in BALB/c mice. CONCLUSIONS: Our results demonstrated that D. candidum had a potent in vitro anti-cancer effect, induced apoptosis, exhibited anti-inflammatory activities, and exerted in vivo anti-metastatic effects.
