BACKGROUND: The size of the baseplate used in reverse total shoulder arthroplasty (RTSA) tends to be larger than the average size of the glenoid in the Korean population. The mismatch between the sizes of the baseplate and the patient's glenoid may result in improper fixation of the glenoid baseplate. This in turn may lead to the premature loosening of the glenoid component. Thus, we evaluated the short-term results of using a 25-mm baseplate in RTSA. METHODS: Seventeen patients with cuff tear arthropathy underwent RTSA with a 25-mm baseplate. The mean age of the patients was 70.1 years, and the mean follow-up period was 14.0 months. We evaluated clinical outcomes preoperatively and postoperatively: the range of shoulder motion, the American Shoulder and Elbow Surgeons (ASES) score, and the Korean Shoulder Society (KSS) score. RESULTS: We found that the mean ASES score and KSS improved from 35.0 to 74.4 (p<0.001) and from 46.9 to 71.8 (p<0.001) with RTSA. The mean forward elevation and abduction, external rotation also improved from 78.6degrees to 134.3degrees (p<0.05) and from 66.6degrees to 125.0degrees (p<0.05), from 20.2degrees to 28.4degrees (p=0.43). Postoperative complications were seen in 12% of patients, but neither the loosening of the glenoid baseplate nor inferior scapular notching were observed. CONCLUSION: In sum, the results of using a 25-mm baseplate in RTSA were similar to those of previous reports. Even though the outcomes are those of a short-term follow-up, neither the loosening of the glenoid baseplate nor the scapular notching were observed.

0.05).Conclusions The expression of PBMC IP-10 mRNA increases in KD.IP-10 may participate in the pathogenesis of KD and CAL in KD.Perhaps the inhibition to the expression of PBMC IP-10 mRNA is one of the mechanisms of IVIG.

Objective To evaluate CT and MRI features of brain lesions in CO poisoning and to compare the ability of detecting rate of lesions by CT and MRI.Methods CT and MRI appearances in 52 cases with CO poisoning were analysed and compared.Results Necroses and degenerations of globus pallidus in 9 cases,cerebral white matter demyelination in 3 cases and brain atrophy in 3 cases were showed by CT.The detecting rate was 28.8% by CT while,necroses and degeneration of glodus pallidus were observed in 24 cases and white matter change in 7 cases were observed by MRI,the detecting rate was 59.6% which was higher than that of CT (?

Forty-two patients with type 2 diabetes mellitus (DM) were refered to 3 groups:type 2 DM without diabetic nephropathy (DN),type 2 DM with DN in the initial stage and type 2 DM with DN in the clinical stage.Ten healthy subjects were served as control group.Plasma adrenomedullin (ADM),urinary?_1- microglobulin (MG) and?_2-MG were detected.The results showed that the level of plasma ADM rose gradually with the development of DN and was positively correlated with markers of tubulointerstiial injury such as urinary?_1- MG and?_2-MG (both P

Objective To probe into the treatment effect and the influencing factors of early goal directed therapy(ECDT)in patients with septic shock.Method One hundred and twenty-six patients with septic shock were assigned into the treatment group(n=62)and the control group(n=64).The treatment group was administrated with EGDT,while the control group used conventional therapy for cycle and capacity support.Then sequential organ failure assessment(SOFA)score,APACHE Ⅱ score before treatment and 28-dav-mortality were respectively recorded before the above-mentioned treatment and at 24 hours after the therapy in the two groups.The treatment group was again subdivided into two groups after 6 hours recovery according to the resuscitation results:the sufficiently resuscitated group(n=40)and insufficiently resuscitated group(n=22).Age,genders,correlated haemodynamic parameter,SOFA score,APACHE Ⅱ score and serum lactic acid concentration before resuscitation and 28 d mortality were compared between the two groups.Results There was no significant difference in SOFA score and APACHE Ⅱ score before resuscitation between the treatment group and the control group[SOFA:(12.26±4.37)vs.(12.54±5.21);APACHE Ⅱ:(21.26±6.03)vs.(21.64±6.80)].The two scores at 24 hours after resuscitation[SOFA:(9.18±3.63)vs.(10.62±4.27);APACHEⅡ:(14.92±3.81)vs.(18.21±4.25);P＜0.05]and 28-day-mortality rate(48.39%vs.76.56%,P＜0.05)of the treatment group were significantly lower than those in the control group.There was significant difference in the age,mean arterial pressure (MAP),APACHEⅡ score between the sufficiently restoring group and the insufficiental resuscitated group.The 28-day-mortality of the sufficiently restoring group was significantly lower than that in the insufficiently restoring group.Conclusions EGDT can improve the prognosis in patients with septic shock.Ages,MAP and APPCHE Ⅱ score before resuscitation can be the important factors of EGDT.

We are reporting a case of 25-year-old male patient with elastosis perforance serpiginosa who showed multipte serpiginous plaques on his neck. Some of the lesions showed hypopigmented, hard, scar-tissue like plaques in the central part. Histologic examination showed hyperplasia and transepidermal elimination of elastic tissue. By electron microscopy, also, we could prove that the elastic fibers were increased in the dermis.

We report a case of primary cutaneous cryptococcosis on the left knee of a 67 year-old woman. She had a large ulcerated and indurated plaque with yellowish purulent exudates on her left knee. A histopathological examination from the lesion showed numerous encapsulated, round spores. Cultures from the lesion showed the presence of Cryptococcus neoforrnans. This may have resulted from an immunosuppressive state due to long-term use of oral corticosteroids.

Objective To retrospectivel y analyze the abdominal CT findings and pathological results of the chronic schist osomiasis so as to improve the diagnostic accuracy of the disease. M ethods The plain abdominal CT scanning was performed in 103 cases an d enhanced CT scanning in 81 cases. The pathological specimen which was consist ent with the section of CT scan was obtained in each cases. Results On CT scanning, liver cirrhosis was seen in 84 cases, various calci fication in liver in 71 cases, liver cancer in 12 cases, enlargement of sple en in 78 cases, calcification in spleen in 13 cases, wall-thickening in colon i n 27 cases, calcification in colon in 31 cases, and colon cancer in 9 cases. Pa thological examination revealed various fibrosis and formation of pseudolobule. The eggs and calcification could be seen in pseudolobule and septa, colonic sub mucosa, and regional lymph nodes. Fibrous hyperplasia in colonic wall and hyper plasia in mucous membrane were obvious. Fibrous hyperplasia and calcification w ere seen in spleen, but the eggs were not found. Conclusion The liver and colon are the major organs affected by chronic schistosomias is in abdomen, and the CT findings are obvious too. The pathological features o f spleen are accompanied with liver cirrhosis. CT is the important imaging meth od in diagnosing chronic schistosomiasis and pathological changes.

Objective Overexpressions of epidermal growth factor(EGF)and EGF receptor have been associ- ated with progression and invasive phenotype of pancreatic cancer.However,the underlying molecular mechanism by which EGF worked in pancreatic cancer cells has not been completely understood.In this study,effect of EGF on the invasion and metastasis of pancreatic cancer cells and its regulatory mechanism were investigated.Methods The effects of EGF on the proliferation,adhesion and invasion of pancreatic cancer cells were detected by WST-1 prolif- eration assay,adhesion assay and invasive assay,respectively.The activity and expression of MMP-2 and MMP-9 were examined by zymography,Western blot and RT-PCR,respectively.The activity of NF-?B was examined by EMSA.Results EGF could significantly promote the invasiveness of pancreatic cancer cells but did not affect cell proliferation or adhesion.The expressions of NF-?B and MMP-9 were significantly increased by EGF,but EGF did not affect the activity and expression of MMP-2.Furthermore,EGF stimulated the NF-?B binding activity.Pre- treatment with NF-?B inhibitors,pyrrolidine dithiocarbamate(PDTC),could significantly inhibit the activity of NF-?B induced by EGF.Meanwhile,the EGF-induced expression and activity of MMP-9,as well as cell invasiveness were also inhibited by NF-?B inhibitor.Conclusion EGF could increase the expression and promote the invasiveness of MMP-9 via the activation of NF-?B in pancreatic cancer cells,which implies that NF-?B inhibitant,such as PDTC,may diminish the invasiveness of pancreatic cancer cells.

Objective To investigate diagnostic efficiency of vascular parameters in the diagnosis of BI-RADS Ⅳ breast masses using three-dimensional power Doppler ultrasound (3D-PDUS).Methods After adjusting the ultrasonic instrument under property conditions,3D-PDUS were applied to scan BI-RADS Ⅳ breast masses before surgery with QLab software,the following parameters of breast masses were obtained:total tumor volume,vascularization index (VI),flow index (FI),and vascularization flow index (VFI).According to the pathological results,the diagnostic value of vascular parameters from 3D-PDUS were assessed with receiver operating characteristic (ROC) curve,and the diagnostic efficiency were analyzed by best cut-off limits of various vascular parameters.Results The volume and vascular parameters of benign group were remarkably lower than those of malignant group (all P ＜0.001).The area under the ROC curve (AUC) of VI (0.873) ＞VFI (0.866) ＞FI (0.778).AUC of FI was significantly smaller than that of VI (P =0.016) and of VFI (P =0.039),while no statistical difference between that of VI and of VFI (P =0.294).The diagnostic accuracies of VI (cut-point:1.2,sensitivity:84.1％,specificity:83.3 ％,accuracy:83.8 ％) and of VFI (cut-point:0.5,sensitivity:82.5 ％,specificity:85.2％,accuracy:82.9％) were higher than that of FI (cut-point:35.3,sensitivity:74.6％,specificity:70.4 ％,accuracy:72.6 ％).AUC of VI (P =0.001) and of VFI (P =0.033) in small-volume group (＜2cm3) were both larger than those of large-volume group (≥2 cm3),no significant difference in AUC of FI between these two groups (P =0.09).Conclusions Vascular parameters obtained using 3D-PDUS have affirmative value in the diagnosis of BI-RADS Ⅳ breast masses,especially in masses less than 2 cm3 in volume.
