To investigate the diagnosis and treatment of renal trauma, a retrospective analysis of 300 patients with renal trauma was carried out. Among them, 274 (91 3%) had blunt renal injuries and 26 (8 7%) had penetrating injuries; 123 (41%) had multiple complicated intraabdominal injuries and 56 (18%) had concomitant shock. The positive rate was 48 7% by regular dose IVU examination and 90 9% by double dose IVU, 79 3% by ultrasonography, and 95 7% by CT. One hundred and eighty five patients were cured by conservative treatment. Fourteen patients died. B ultrasound could be conveniently used for primary assessment of renal injuries, while CT showed rapid and accurate condition of a renal trauma patient. The treatment depends on the severity of the injury. The conservative treatment was employed in most cases which present slight or moderate injury with no evident massive bleeding. Severe injury required surgical exploration. The operative approach was done through a transabdominal incision, which made it relatively easy to explore the abdominal contents and to manage the injured kidney. It was also very important to control shock and prevent other severe complications in the early stage of the treatment.

AIM:To observe the preliminary efficacy of conbercept injected intravitreally for the treatment of wet age-related macular degeneration(wAMD).METHODS:Seventeen wAMD patients (18 eyes) were selected to receive conbercept injection.All patients were given a single conbercept injection every month,3 times.Before and after 1,2,3mo of the injection,the best corrected visual acuity (BCVA),intraocular pressure (IOP,measured by Non-contact tonometer),fundus photography,fundus fluorescein angiography(FFA),indocyanine green angiography(ICG),optical coherence tomography(OCT) examination and the complications incidence were compared.RESULTS:Three months after conbercept injection,the BCVA improved in 15 eyes (83%),stable in 3 eyes (17%).Before treatment,the average central macular thickness was 421.72±54.43μm,at 1 and 2 and 3mo after treatment,the average central macular thickness was 337.89±25.88μm,293.56±26.87μm,266.89±19.10μm respectively.There were significant differences compared with before and after injection(P<0.05).In the final follow up,FFA and ICG showed that the leakage in macular area disappeared in 15 eyes (83%),still existed in 3 eyes (17%),in those 3 eyes the injection was given for one or two times till the leakage disappeared.Elevated intraocular pressure occurred in 2 cases (26mmHg,23mmHg),after 1d down to normal.Another patient showed postoperative envy,given left ofloxacin eye drops after 2d,then back to normal.There was no serious ocular adverse reactions.CONCLUSION:Intravitreal injection conbercept for wAMD can significantly improve the visual function,reduce the macular edema and the leakage with higher safety and less complications.However the prolonged efficacy needs further observation.

A method of simultaneous determination of the eleven phenol and aniline dyes in oxidative hair dyes by ultrasonic-assisted extraction and high performance liquid chromatography-tandem mass spectrometry was developed. The orthogonal and single-factor experiments were designed to and optimize the ultrasonic-assisted extraction conditions, and the samples were extracted using 10 mL of 5% methanol under the conditions of ascorbic acid as an antioxidant for 10 min. The gradient elution program and the electrospray ionization mode change were together used for the optimization of the measurements, and the determinations were completed by using the multi-reaction monitoring scan. The detection limits were 1. 15-9. 43 μg/g, the recoveries of spiked samples were 88. 0%-118. 1%. The method can be used to determine trace prohibited and restricted dyes in hair dyes.

Purpose:To study whether the inhibition of phosphatidylinositol 3-kinase (PI3K)/Akt survival pathway could sensitize the response of tumor cells to some chemotherapyeutic agents. Methods:The different tumor cells has been treated with the combination of isoform specific Akt inhibitor and either adriamycin or camptothecin; the quantitation of the induction of apoptosis by drugs has been estimated with caspase 3 assay; immunoprecipitation western blotting has been used to evaluate the inhibition of the phosphorylation of different isoforms of Akt after the treatment. Results:①The inhibitors could reduce the phosphorylation of Threonine 308 and Serine 473 of isoform specific Akt. ②The inhibition of any one isoform specific Akt could not reverse the resistance of tumor cells tested to chemotherapeutic drugs, but it is not the same case if blocking of two isoforms of both Akt1 and Akt2 was done at the same time. ③The synergistic effects of Akt inhibitors is maybe relative to the level of endogenous PTEN(phosphatase and tensin homolog deleted on chromosome 10) expression. Conclusions:It is required to inhibit two isoforms of both Akt1 and Akt2 in order to maximally sensitize the tumor cells to chemotherapy.

Objective To compare the resonance acoustic characteristics between 7~16 years old Down syn-drome children and normal children .Methods A total of 29 cases of 7~16 years old Down syndrome children and 90 cases of 7~16 years old normal children pronuanced /a/,/u/,/i/,each sound for 3 times ,every time 1 to 2 sec-onds .The oral resonance acoustic parameters ,including F1 (a) ,F2 (a) ,F1 (i) ,F2 (i) ,F1 (u) ,F2 (u) ,the distance of tongue and the distance of jaw ,were recorded by real analysis .Analysis of variance was used for the voice acous-tic .Results With age ,there was a significant decrease tendency of the value of F2 (a) and a very significant growth tendency of the values of F2 (i) and the distance of tongue in normal children .The value of F2 (i) inrcreased signifi-cantly in Down syndrome children .The values of every oral resonance acoustic parameters were not different signifi-cantly on sex in normal children .The values of F1 (i) and F1 (u) in Down syndrome boys were significantly less than those of in the Down syndrome girls ,but the the distance of jaw in Down syndrome boys were significantly greater than those of in the Down syndrome girls .The values of F2 (u) and F1 (i) in Down syndrome children were signifi-cantly greater than those of in normal children ,but the distance of tongue was significantly less than those of in nor-mal children .Conclusion With age ,in normal children ,the amplitude of the tongue forward movement and the range of tongue back and forward movement were increased significantly ,the oral focus moved forward gradually .In Down syndrome children ,the amplitude of the tongue back movement ,and the range of tongue back and forward movement ,were poor than those of in normal children .The Down syndrome children were easier to suffer from oral resonance disorder than normal children .

Objective:To observe the effect of Bailing capsules adjuvant therapy on urinary monocyte chemoattractant protein-1( MCP-1), microalbuminuria(mAlb) and 24h urinary protein(Up)in the children with henoch-schonlein purpura nephritis(HSPN). Methods:Totally 64 cases of HSPN children were randomly divided into two groups with 32 cases in each .The normal group was given the conventional hormone , dipyridamole and loratadine etc .The Bailing group was orally treated with Bailing capsules additionally .The therapy course was 4 weeks, the changes of MCP-1,mAlb and 24hUp in the groups before and after the treatment were observed .Re-sults:Before the treatment, the levels of MCP-1,mAlb and 24hUp were similar between the groups (P>0.05).After the 4-week treatment, the levels of MCP-1,mAlb and 24hUp were lower than those before the treatment (P<0.05),and the decrease in Bailing group was more significant than that in the normal group (P<0.05).Conclusion:Bailing capsules adjuvant treatment for HSPN can significantly reduce albuminuria and improve renal function .

Objective To investigate the changes of plasma microRNA-223 (miR-223) in pediatric severe pneumonia patients and its relationship with severe pneumonia.Methods There were 50 children with severe pneumonia enrolled in the study (observation group),and 50 healthy children were selected as control group (normal control group).The expression levels of plasma miR-223 were detected by real time polymerase chain reaction.The relationship between miR-223 and procalcitonin (PCT),C-reactive protein (CRP),tumor necrosis factor-α (TNF)-α,and interleukin (IL)-10 were analyzed.The predictive value of miR-223 in plasma,PCT,and CRP to severe pneumonia was evaluated by receiver operating characteristic (ROC) curve.The relationship between miR-223,T cells,TNF-α,and IL-10 was analyzed.Results The plasma miR-223 expression levels in observation group were upregulated compared to those in the normal control group [(16.01 ± 5.17) × 10-4 mg/L vs (5.44 ± 2.21) × 10-4 mg/L,t =7.46,P ＜ 0.01].The CRP and PCT expression levels in severe pneumonia patients were higher than those of the normal control group [z =5.496,5.198,P ＜0.05,orP ＜0.01].The expressions of CD4+ CD25+Treg,miR-223,and IL-10 in observation group were higher than those of normal control group (P ＜0.05).The expression of CD4 + CD25 + Treg,miR-223,and IL-10 in the death children were higher.There was a positive correlation between miR-223 and IL-10 (r =0.335,0.571,P ＜ 0.01).The sensitivity and specific degrees to predict the severe pneumonia in mir-223,PCT,and CRP were 83.79％,86.12％,66.68％,91.05％,78.01％,and 44.23％,respectively.miR-223 was better than PCT and CRP to predict severe pneumonia in children.Conclusions The expression levels of plasma miR-223 in children with severe pneumonia could reflect the immunity,and it can be used as early prognostic markers to reflect the severity of inflammation in some degree.
