Objective To observe the characteristic features of musculoskeletal ultrasound (MSUS) in gouty arthritis (GA) and to assess its value in GA diagnosis.Methods Patients with GA and non-GA who underwent MSUS examination in Chinese PLA General Hospital were enrolled in this study. The synovitis,tenosynovitis,soft tissue swelling,bone erosion,bursitis and ossification were measured by greyscale ultrasound,and the synovial vascularity was measured by power Doppler ultrasound to evaluate the degree of inflammation.Results The ultrasound images of GA were intended to have specific features like tophus,hyperechoic deposition on the surface of the articular hyaline cartilage ( double contour sign ),hyperechoic deposition in the synovium appearing as bright stippled foci,and bright strap in tendons with a significant difference when compared with non-GA group (P ＜ 0.05).The percentage of tenosynovitis and bone erosion in non-GA group was higher than that in the GA group with a significant difference (P ＜0.05 ). Tophus,double contour sign,bright stippled foci or bright stippled foci in tendons together suggested gout with a specificity of 92.4％ and a sensitivity of 60.3％,the AUC of ROC was 0.764 ( P ＜0.05).Conclusion Tophus,double contour sign,bright foci and bright strap detected by MSUS are of diagnostic value on GA and MSUS may be a promising tool in diagnosing GA.

Objective To investigate the clinical value of color Doppler ultrasound in the early diagnosis of acute cholecystitis infection ,in order to improve the diagnosis of acute cholecystitis infection .Methods 36 cases with acute cholecystitis infection were selected as the observation group , and during the same period the healthy people were randomly selected as the control group .The color Doppler performance of ultrasound was observed .The hepatic artery blood flow velocity and the maximum peak of the cystic artery (Vmax) and resistance index(RI) were meas-ured.ROC curve was observed to evaluate the specificity of color Doppler ultrasound for the disease .Results The incidence rates of weak bile sound transmission ,gallbladder wall thickness ,gallbladder enlargement ,ultrasound Mur-phy positive in the control group were 25.0%,16.7%,22.2%,8.3%,which in the observation group were 72.2%, 47.2%,100.0%,94.4%,the differences were statistically significant (χ2 =4.571,4.571,4.589,5.689,all P<0.05).The differences in hepatic artery and the cystic artery Vmax and RI were statistically significant between the two groups(P<0.05).ROC curve comparison showed that the correct rate of gallbladder enlargement in the observa -tion group was the highest (90.7%),the specificity was 90.7%,sensitivity was 90.6%,and other indicators of ultra-sound had no significant difference (χ2 =0.893,P>0.05).Conclusion Color Doppler ultrasound can show the form of acute infectious cholecystitis ,gallbladder wall degree of bile through sound etc .,it can improve the diagnostic value of the disease.

AIM: To investigate the effect of LY980503(a benflumetol derivative)on multidrug resistance of tumor cell line using DNA microarray. METHODS: Total RNA was extracted from multidrug resistant MCF/DOX cell line. cDNA microarray containing 320 cDNAs was used to detect the gene expression profile. RESULTS: 9 down-regulated genes and 1 up-regulated gene were identified after multidrug resistant MCF/DOX cells were treated with LY980503. CONCLUSION: LY980503 can effectively reverse the resistance of MCF/DOX to DOX in vitro by adjusting the expression of multi-genes.

Objective To investigate the changes of blood lipid,endothelin(ET)and carbohydrate tolerance in simple obesity children.Methods Serum total cholesterol(TC),triglyeride(TG),low density lipoprotein(LDL),endothelin(ET) and oral glucose tolerance test(OGTT) of 436 cases(light obesity group 242,moderate obesity group 138,heavy obesity group 56) were detected respectively.Results The levels of TC,TG,LDL,ET and OGTT in 3 simple obesity groups were all higher than those in control group obviously and there were significant differences.The significant positive correlation between the obesity children serum lipids,ET and obese degrees were observed.Four insulin resistant children were found in heavy obesity group and none in other groups.Conclusions The levels of serum lipids and ET increases in obesity children and the OGTT decreases in some heavy obesity children.For preventing the obesity related health problems,the simple obesity children should be paid more attention to earlier.

With building up a clinical modification system model by upgrading the standard disease classification system architecture,to collect those huge amount of diagnosis names and codes in use,based on the model to screen and coordinate the relation of them,the tenth revision of the International Classification of Disease Clinical Modification of Beijing is implemented.This standard has been successfully applied for two years in all those secondary and above level hospitals in Beijing.It could well support the work of deploying Diagnosis Related Groups in Beijing and support not only those traditional applications of disease classification but also those new and advance requirements of information processing.

Objective:To introduce a new style of platysma myocutaneous flap and to evaluate its application value in the restoration of oral-maxiofacial defects.Methods:Platysma myocutaneous flap with apron incision was used for the restoration of oral-maxiofacial defects after oral lesion ablation in 15 cases from January,2014 to September,2015.The platysma muocutaneous flap was harvested with a U shaped apron incision.The skin above the flap pedicle was preserved.The platysma pedicle was widened to ensure the flap survival.All the patients were followed up form 4 to 33 months.Results:Of the 15 platysma myocutaneous flaps,12 survived completely and 3 had partial flap necrosis.The total survival rate of the flaps at the recipient site of buccal mucosa,tongue and alveolar was 8/9,1/3 and 3/3 respectively.Additionally,there were 2 cases of disturbed wound healing in the neck.Except for 1 case of carcinoma of gingiva which had apparent cervical scar and 1 case of tongue carcinoma which had limited tongue mobility,the other cases showed a satisfactory recovery of oral-maxillofacial contour and fucnction.Conclusion:Compared with the traditional platysma myocutaneous flap,the platysma myocutaneous flap with apron incision can provide a larger skin paddle,and is suitable for the restoration of small and medium sized buccal mucosa and alveloar defects,but not for tongue defect.

OBJECTIVE: To clarify the effect of Jisuikang on Nogo-66 receptor NgR expression after spinal cord injury.
METHODS: 144 rats were randomly divided into six groups: sham surgery group, model group, prednisone group, high-, moderate- and low-dose Jisuikang groups (n=24). Animal models of spinal cord injury were established by the modified Allen’s method in the later five groups. Rats in the prednisone group were daily given 0.06 g/kg prednisone acetate by lavage, once a day. Rats in the high-, moderate- and low-dose Jisuikang groups were daily intragastrically given 12.5, 25 and 50 g/kg Jisuikang, once a day. Rats in the sham surgery and model groups were intragastrically daily given 20 mL of saline, once a day. Rats in each group were administered drugs until death.
RESULTS AND CONCLUSION: Compared with the model group, NgR protein and mRNA expression levels were significantly lower in the prednisone, moderate-and low-dose Jisuikang groups. These data suggested that Jisuikang can improve the recovery of neurological function after spinal cord injury and effectively inhibit NgR protein expression at the site of injury so as to suppress the microenvironment factors harmful to nerve regeneration and further improve the microenvironment of nerve regeneration.
