Objective To increase the awareness of thyroid diseases through observing the relationship between ultrasound indications of thyroid and thyroid disease,and to enhance the understanding of thyroid disease through outpatient data.Methods Two hundred women aged 25 to 50 with thyroid imaging data were selected from the Department of Ultrasonography,the First Affiliated Hospital of Harbin Medical University.Seven indications including age,body weight,thyroid volume,the number of nodules,nodule size,nature of nodules and thyroid disease were recorded.Thyroid cases were divided into four groups based on their sonographic changes of color Doppler ultrasound:normal group (136 cases):sonographic changes of thyroid were approximately normal ; mild degree group (9 cases):consisting of patients with mild thyroid disease,diffused thyroid enlargement or combined cystic nodules; moderate degree group (38 cases):consisting of patients with moderate thyroid disease,hyperthyroidism or hypothyroidism; severe degree group (17 cases):consisting of patients with severe thyroid disease,thyroiditis and/or with hemorrhage and calcification.Data were analyzed using the method of clinical case observation and SPSS 16.0.Results We found that in mild degree group the discriminant coefficients of thyroid volume,the nature of thyroid nodules and nodule size were 0.085,0.169 and 0.695; but in sever degree group the corresponding values were 0.158,0.344 and 0.484,respectively,and the difference between the two groups was statistically significant (x2 =43.3,df =18,P ＜ 0.01).Conclusions The nature,size and area of thyroid nodules are closely related to the progression of thyroid disease.The color Doppler ultrasound data of outpatients as a part of hospital statistics have important theoretical and practical value.

OBJECTIVETo investigate the relationship between chronic pyelonephritis (CPN) and immune function, and the therapeutic mechanism of Yishenkang granule (YSKG).

METHODSOne hundred and twenty patients of CPN were divided into 3 groups randomly, the YSKG group (treated with YSKG), the control A group (treated with Sanjin tablet) and the control B group (treated with western medicine). Serum levels of immunoglobulin (Ig), complement 3 (C3), interleukin-2 (IL-2), peripheral T-lymphocyte subsets, and urinary secretory immunoglobulin A (sIgA) were determined before and after treatment with monoclonal antibody assay, agar diffusion method, radioimmunoassay (RIA), and radioimmuno-equilibrium method, and compared with normal control.

RESULTSThere were disorders of T-lymphocyte subsets in CPN, lowering of serum Ig, C3 and urinary sIgA, and increase of blood IL-2 (P < 0.05 or P < 0.01). These abnormalities could be normalized after YSKG treatment.

CONCLUSIONFunctional disorders of cellular and humoral immunity exist in CPN patients of chronic stage, YSKG could correct the immune functional disorder, control the recurrence of CPN effectively and alleviate the immunopathological damage.

Objective To observe the expression of matrix metalloproteinases(MMP)-1,MMP-3 and iNOS in cartilage of experimental rabbit osteoarthritis at different time intervals after anterior cruciate ligament transection(ACLT)operation.The aim of this study is to provide the theoritical evidence for using ACLT rabbit model in Osteoarthritis(OA)research.Methods Unilateral ACLT was performed on 27 randomly selected while rabbits and underwent unilateral arthrotomy was performed on the other 9 white rabbits as the control group.Nine randomly selected white rabbits in experimental group were killed and 3 white rabbits in the control group at 4th,8th and 12th week respectively.Cartilage degradation of femoral condyles was evaluated macr-oscopically,mRNA expression level and protein expression level of MMP-1,MMP-3 and iNOS was measured by reverse transcription-polymerase chain reaction(RT-PCR)and immunohistochemistry respectively.Results Forepart OA cartilage degradation was observed at the 4th week and became more severe at the 8th week after ACLF.Afterpart cartilage degradation was evident at the 12th week after ACLT while cartilage still remained normal in the control group,mRNA expression level and protein expression level of MMP-1.MMP-3 and iNOS were increased at the 4th week and became higher gradually at the 8th,12th week after ACLT compared with the control group.Expression distribution of MMP-1,MMP-3 and iNOS bad different patterns respectively.Conclusion It is suggested that the process of OA cartilage degradation can be simulated by ACLT model and MMP-1,MMP-3 and iNOS may be good markers in therapeutical research of OA.

Objective To investigate the efficiency and safety of articulating spacer for severe infected knee arthroplasty in patients with medical comorbidities and local sinus tracts. Methods Ten consecutive patients with medical comorbidities (rheumatoid arthritis, diabetes mellitus, etc) or local sinus tracts,who were complicated with late infected TKA, were included in the study. All the patients underwent twostage revision using articulating spacers. All of the patients were debridement thoroughly and followed by implantation of an antibiotic-loaded cement articulated spacer. Two-stage revisions were not followed untill the infection were controlled. The hospital for special surgery (HSS) knee scoring system and range of motion were used to evaluate the outcomes. Results One patient underwent knee fusion because the infection was not controlled after first-stage surgery. The other 9 patients had no evidence of infection. The mean follow-up was 50 months (range, 24-90 months), no recurrent infection developed for these 9 patients. The mean modified HSS score had improved from 48 points (range, 32-63) before the resection surgery to 79 points (range,62-91) at the end of the spacer period. At the latest follow-up, the modified HSS score averaged 89 points (range, 74-95). The good and excellent rate was 0, 80% and 100%, respectively. The average range of motion had increased from 13°-70° preoperatively to 8°-93° prior to the revision. And at the latest follow-up, the range of motion averaged 3° to 110°. Conclusion The delayed two-stage revision using an articulating spacer is effective in the treatment of chronically infected TKA characterized by simple, good reproducible, high rate of infection control, better joint function after surgeries

Objective To investigate the early effect of medium-dose ionic irradiation on the expression of Fos protein in the rat brain. Methods Fos protein was observed in rat brains at times ranging from 24 hours to 4 weeks after hemispheric irradiation (single-fraction maximal dose of 20Gy) with the immunohistochemical technique. Results Compared with that of the un-radiated rats,the expression of Fos protein in the irradiated brain decreased distinctly 24 hours and 1 week after irradiation.However,the quantity of Fos immunopositive cells increased gradually afterwards.At four weeks after radiation,expression of Fos protein recovered progressively in medulla oblongata and pons,in which Fos immunopositive cells were more than those in control group.In contrast,expression level of Fos protein in mesencephalon,diencephalons or telencephalon was still less compared with that of the un-irradiated rats.Conclusion The result suggested that the neuronal activity might be inhibited in certain nuclei of the rat brain in early stages after hemisphere irradiation,and this inhibitory phenomenon was more obviously in higher neural centers.

Objective To study the role of lipase in inflammation in patients with acute pancreatitis.Methods Acute pancreatitis patients (n =200) were enrolled in the study.The patients were examined by computerized tomography and the severity of AP is determined by Blathazat Score.We assess the muhivariate-adjusted association of amylase and lipase with inflammatory markers of AP.We identified that lipase was more specifically correlated with AP progression than amylase,lactate dehydrogenase and creatitine kinase.Results We demonstrated that in AP patients,a doubling of lipase excretion was associated with 6.8％ increase of white blood cells (95％ CI,3.06％-10.5％,P ＜ 0.01),10.3％ (95％ CI,5.7％-14.9％,P ＜ 0.01) increase of neutrophil number but 14.8％ (95％ CI,2.3％-27.3％,P ＜0.05) decrease of lymphocytes in the blood,respectively.By contrast,amylase has no association with these cells.Both amylase and lipase had no relationship with triglyceride level in AP patients.Conclusions Lipase serves as an indicator for the severity and treatment of AP.

Objective To explore the feasibility and efficacy of posterior minimally invasive scoliosis surgery in Lenke 5C adolescent idiopathic scoliosis (AIS).Methods From November 2012 to March 2014,a total of 16 patients underwent posterior minimally invasive scoliosis surgery assisted by O-arm three-dimensional CT navigation were included.There were 14 female and 2 male,with an average age of (16.7± 1.6) years (ranged from 14 to 18 years).The mean Cobb angles of lumbar and thoracic curve were 48.7°±5.6°and 24.1°±5.4°,respectively.Results 16 patients were successfully completed the operation,the average operation time was (246±89) min,the average intraoperative blood loss was (192± 105) ml,and the fusion level was 4.9±0.5 on average.A total of 155 screws were inserted in the 16 patients,with a mean implant density of 98.9％±4.9％.All the patients were followed up for (26.4±3.9) months on average.The following radiographic parameters were evaluated before surgery,immediately after surgery and at the last follow-up:curve magnitude,apical vertebral translation (AVT),apical vertebral rotation (AVR),trunk shift,thoracic kyphosis (TK),thoracolumbar kyphosis (TLK),lumbar lordosis (LL) and sagittal vertical axis (SVA).The accuracy of pedicle screw placement was assessed according to postoperative CT scans.SRS-22 scores and complications were also recorded during the follow-up.Immediately after surgery,the correction rate of main lumbar curve was 80.1％±8.3％,and thoracic curve was 59.3％±8.7％,and a obvious improvement was noted in terms of AVT,AVR,trunk shift and TLK.At the last follow-up,except the increase of SVA from (-27.6± 19.5) mm to (-12.3±6.6) mm,no obvious changes of AVT,AVR,trunk shift,TK,TLK and LL were observed during the follow-up.According to CT evaluation,the satisfactory rate of pedicle screw placement was 94.2％,while the perforation rate was 5.8％ (9/155).Fusion across the facet joint were satisfactory.In SRS-22 assessment,the mean scores of functional,pain,self-image,mental state and satisfaction were (4.3 ± 0.5) points,(4.7 ± 0.6) points,(4.2 ± 0.7) points,(4.2 ± 0.5)points and (4.4 ± 0.6) points.No wound infection,implant failure and neurologic complications were found after surgery.Conclusion Wiltse approach assisted by O-arm three-dimensional CT navigation has the characteristics of small injury,less bleeding,high accuracy placement of pedicle screws and high self-satisfaction of patients.It is a feasible,safe and effective way to treat Lenke 5C AIS.

Objective To examine the independent effect of depression on activities of daily living of patients with mild cognitive impairment (MCI). Methods Data were obtained through the face-to-face interview. Totally 154 elderly patients that were screened from 552 old people by the Montreal Cognitive Assessment (MoCA) were diagnosed as MCI. They were investigated with the Geriatric Depression Scale, and instrumental ability of daily living (IADL) were measured by the Functional Activities Questionnaire. The effect of depression on IADL of patients with MCI was analyzed by logistic regression analysis. Results The prevalence of depressive symptoms among Chinese elders with MCI was 31.82％. The scores of Medical Outcomes Study Social Support Survey, and Functional Activity Questionnaire of depression group and non-depression group were significantly different (P<0.05) . Logistic regression analysis showed that scores of Functional Activity Questionnaire was positively associated with the scores of Memory Inventory for the Chinese (OR=1.36, 95％ CI: 1.15-1.61) and depression (OR=6.19, 95％ CI:2.07-18.55) . Conclusion The prevalence of depression in elderly patients with MCI was high. Depression would significantly reduce the IADL of the old patients with MCI. Medical workers should be aware of the extent and impact of depressive symptoms in MCI and take active measures in evaluating and treating the depressive symptoms.
