Objective To investigate the clinical significance and effect of total hip arthroplasty (THA) in treatment of bony ankylosis of the hip in patients with ankylosing spondylitis (AS).Methods The study enrolled 23 patients (35 hips) undergone THA for bony ankylosis of the hip in AS between March 2008 and November 2012.Postoperative outcome was measured based on Harris hip score and Xray images.Results Preoperative Harris hip score of (27.6 ± 2.3) points increased to (86.7 ± 2.6)points postoperatively.Hip flexion and adduction deformity presented correction postoperatively.Total hip range of motion (flexion,adduction,abduction,and external rotation) improved from (45.7 ±5.3) o preoperatively to (206.9-±4.7) °postoperatively and mean hip flexion activity was 81 °.Hip activity achieved significant improvement and pain was relieved.X-ray films revealed proper position of prostheses without the presence of loosening or subsidence.Two patients (3 hips) experienced mild pain after a long period of walking.Four patients had heterotypic ossification including Brooker grade Ⅱ in one patient and Brooker grade Ⅰ in three.Conclusion THA is an effective treatment for bony ankylosis of the hip in AS,for it rebuilds joint function,relieves pain of the hip and improves patients' quality of life.

Objective To explore an optimal cut-off value of waist circumference(WC)for identifying metabolic syndrome(MS)in middle-aged and elder residents in an urban community.Methods Database of 1558 residents aged 40-79 years at high-risk in screening for diabetes from Changfeng community,Putuo District,Shanghai during 2005 to 2007 was used to analyze sensitivity and specificity of varied cut-off values of WC for identifying two or more components of MS in men and women,respectively.Receiver operating characteristics(ROC)curve was used to explore the optimal value.Results Optimal cut-off value of WC was 85.0 cm for men and 80.0 cm for women,respectively,for identifying two or more components of MS bv ROC curve,with sensitivity of 72.3%and 74.9%,and specificity of 50.2%and 62.2%,respectively.Based on that optimal cut-off value of WC and definition of International Diabetes Federation(IOF),prevalence of MS was 38.8%in this population,40.7%in men and 37.8%in women,respectively.Conclusion The optimal cut-off value of WC was 85.0 cm in men and 80.0 cm in women,respectively,for identifying MS in the middle-aged and eldedy in an urban community of Shanghai.

Objective To compare the value of clinical application of the ratio of urine albumin to creatinine (ACR) in the community-dwelled middle-aged and elderly at high-risk for diabetes in screening for albuminuria with casual and morning urine specimens. Methods Totally, 443 middle-aged and elderly people (234 men and 209 women) at high-risk for diabetes, with an average age of (59±8) years, were recruited from Changfeng Community of Shanghai in screening for albuminuria with casual and morning urine specimens collected on the same day, as well as another two morning urine specimens collected at an interval of two weeks, for determination of urine ACR. Albuminuria was defined as ACR equal to or more than 30 mg (albumin)/g (creatinnine) in two or more of the three urine specimens collected. Results Overall prevalence of albuminuria was 6. 3% ( 28/443 ) in the middle-aged and elderly according to diagnostic standard mentioned above, significantly higher in casual urine specimens than in morning urine specimens (14. 9% vs. 5.9%, P <0. 05). Urine ACR of casual urine specimens was significantly higher than that of morning urine (7. 1 mg/g vs. 3. 2 mg/g, P<0. 001 ). There was no significant difference in sensitivity and positive predictive value (PPV) between casual and morning urine specimens in screening for albuminuria (96. 4% vs. 92. 9%, and 99.7% vs. 99. 5%, respectively, P >0. 05). Specificity and negative predictive value (NPV) of casual urine specimens was significantly lower than those of morning urine specimens (90.6% vs. 100.0%, and 40.9% vs. 100.0%, respectively, P<0.05). The optimal cut-off value of ACR by casual urine specimens was 40. 0 mg/g in screening for albuminuria, based on receiver operating characteristic (ROC) curve, with sensitivity of 96. 4%, specificity 95.2%, PPV 57.5% and NPV 99. 8%. The middle-aged and elderly with negative albuminuria in morning urine but positive in casual urine had more risk factors for cardiovascular and chronic kidney diseases than those with negative albuminuria in both morning and casual urine specimens. Conclusions Morning urine specimen is better than casual urine for albuminuria screening in the middle-aged and elderly people with risk factors for diabetes in urban community, but casual urine used in screening for albuminuria is very convenient for collection. It is suggested that urine ACR of 40. 0 mg/g be used as an optimal cut-off value for casual urine in albuminuria screening among them.

Objective To investigate the radiographic classification and presentation of atypical spinal tuberculosis in adults.Methods Data of 45 consecutive patients who had suffered from atypical spinal tuberculosis confirmed by surgical interventions and pathologic examinations at our department from February 2000 to August 2012 were retrospectively analyzed.There were 29 males and 16 females,aged from 20 to 71 years (mean,46.2 years).Twenty-five patients presented with low-grade fever,lassitude and loss of weight,and the other 20 patients denied the constitutional symptoms of tuberculosis.An increased erythrocyte sedimentation rate (range,25-107 mm/1 h) was found in 37 patients.All patients were investigated by the following imaging resources:plain X-rays,CT scan and MRI.3D reconstruction CT was performed in 12 patients and PET-CT was performed in 2 patients.All patients were treated surgically and confirmed by pathologic examinations and 3 patients had undergone CT-guided biopsy.Results Atypical spinal tuberculosis presented in different radiographic presentation forms.Nine patients had involvement of a single vertebral body,which was depicted with nonuniformly increased signal intensity on T2-weighted MR images.CT scan showed irregular bony destruction in old patients and solitary osteolytic lesion with well-defined margins in young adults.There were 2 cases of isolated affection in the posterior elements (vertebral appendages type),and the involved vertebral appendages demonstrated hyperintense signal on T2-weighted MR images and bony destruction on CT scan.There were 8 cases of simultaneous affection in the anterior and posterior element of one vertebra (circumferential vertebral involvement type),and CT scan showed multiple bony destruction in vertebral body and neural arch.There were 5 cases of affection in disc (intervertebral disc involvement type),which presented decreased signal in MRI and protruding disc pressing the dural sac could be found.There were 14 cases of multiple vertebral tuberculosis in continuity (contiguous spinal tuberculosis),which presented multiple tuberculosis lesions on 3D-CT.There were 7 cases of multiple vertebral tuberculosis in noncontinuity (noncontiguous spinal tuberculosis),which presented destructive tubercular lesions affected different levels in different regions of the spine on MRI.Conclusion Atypical spinal tuberculosis had multiply radiographic presentation forms and atypical radiographic features.Worm-eaten destruction of bone or vertebral endplate,marrow edema and increased signal intensity of paraspinal ligament are features of radiographic presentation in diagnosis of atypical spinal tuberculosis.

Objective To discussion the feasibility and effect of total hip arthroplasty (THA) of postoperative ankylosis in patients with hip peripheral fracture.Methods From January 2008 to October2013,cementless THA was performed in 23 patients with ankylosis after internal fixation of hip peripheral fracture.There were 16 males and 7 females,aged 23 to 67 years (mean,43 years).Interval between internal fixation and THA was 12 to 73 months (mean,38 months).Results Mean follow-up was 28 months (range,3 to 60 months).All patients presented good press-fit prostheses with mean acetabular valgus of 43.3°,mean acetabular anteversion of 22.5°,and mean femoral anteversion of 16.4°.Primary wound healing was detected with no occurrence of infection,prosthetic loosening or dislocation,and periprosthetic fracture.Femoral vein incomplete embolism was diagnosed in one patient with limb swelling 2 months after operation,but swelling subsided after 3 months of bed rest,elevation of the affected limb and anticoagulant therapy.Length of the bilateral limbs was almost equal in 19 patients with the difference within 0.5 cm,but the affected limb was 0.8-1.4 cm shorter in 3 patients and was 0.8 cm longer in 1 patient.Harris hip score improved from (42.16 ± 3.03)points before operation to (93.08 ± 5.23) points at the last follow-up (P ＜ 0.05).Conclusion THA is associated with good hip function recovery and improved quality of life during the treatment of postoperative ankylosis in patients with hip peripheral fracture.

OBJECTIVETo investigate the association of retinal vascular calibers with hyperuricemia in a middle-aged and elderly population.

METHODSA cross-sectional design was applied in this study and 869 participants aged =40 years from a high-risk group for diabetes were recruited. All participants received the anthropometrical measurements and laboratory tests. Retinal arteriolar and venular caliber of the participants were measured with a semi-automated system. Hyperuricemia was defined as a serum uric acid level >420 μmol/L in men and >360 μmol/L in women. Linear regression models were used to assess the association of hyperuricemia with retinal vascular calibers. These models were additionally adjusted for age, central obesity, hypertension, dyslipidemia, weekly activity, smoking status, and education.

RESULTSAmong the 869 participants, 133 (15.3%) suffered from hyperuricemia. The crude mean serum uric acid level was 312.3 μmol/L (Standard Deviation 79.5); mean concentration was 355.0 μmol/L (SD 75.5) in male participants, and 288.0 μmol/L (SD 71.1) in female participants (age-adjusted difference 58.1 μmol/L, 95% Confidence Internal 48.5, 67.6). After adjusting for additional covariates, male participants with hyperuricemia had 3.77 μm (95% CI -0.46, 8.00) smaller arteriolar caliber and 6.20 μm (95% CI 0.36, 12.04) larger venule than those without hyperuricemia; the corresponding numbers among female participants were 1.57 μm (95% CI -1.07, 4.21) for retinal arteriolar caliber and 2.28 μm (95% CI -1.72, 6.27) for retinal venular caliber.

CONCLUSIONHyperuricemia was associated with smaller retinal arteriolar caliber and larger venular caliber mainly in male participants in this study.

Objective To investigate prevalence of metabolic syndrome (MS) in population at high-risk for diabetes in Changfeng community of Shanghai. Methods Totally, 982 persons aged 40-79 years without previous history of diabetes, but with risk factors for diabetes from Changfeng community in Shanghai were screened by questionnaire, physical examinations, lipid profile and oral glucose tolerance test. Prevalence of MS and its clinical characteristic were observed. Results Overall prevalence of MS was 44. 6% (438/982) in Changfeng community, significantly higher in women of 48.6% (341/701) than that in men of 34. 5% (97/281) (P<0.01). Prevalence of MS increased with age in women (P <0. 01 ), but not in men (P>0.05). Components of MS ranking from high to low were hypertension of 66. 5% (653/982), abdominal obesity of 62.8% (617/982), decreased high-density lipoprotein-cholesterol (HDL-C) of 49. 4% (485/982), increased triglyceride (TG) of 46. 0% (452/982) and increased fasting glucose of 35.7% (351/982). There were 55.9% (245/438) of MS patients with three or more MS components in addition to abdominal obesity. Conclusions Prevalence of MS is higher in community population at high-risk for diabetes and more than half of the MS patients have three or more risk factors for cardiovascular disease.

Objective:To investigate the diagnostic value of nucleic acid matrix-assisted laser desorption ionization-time of flight mass spectrometry（MALDI-TOF MS）in sputum smear-negative patients with nontuberculous Mycobacterial（NTM）pulmonary disease.Methods:Clinical data of 123 patients suspected of NTM pulmonary disease admitted in Public Health Clinical Center Affiliated to Shandong University between July 2022 and November 2023 were retrospectively analyzed. Bronchoalveolar lavage fluid（BALF）specimens were collected for MALDI-TOF MS assay and MGIT 960 culture. The diagnostic efficacy of MALDI-TOF MS for NTM pulmonary disease in patients with negative sputum smears for acid-fast bacilli was evaluated with receiver operating characteristic（ROC）curve. Statistical analysis was performed using SPSS 26.0 software and MedCalc statistical software.Results:Diagnosis of NTM pulmonary disease was finally confirmed in 66 out of the 123 suspected patients. It took 8 to 24 h for MALDI-TOF MS to identify NTM species and resistance. By MALDI-TOF MS，72 NTM strains were identified，with the Mycobacterium avium complex being the most prevalent（34 strains，47.22%），followed by the Mycobacterium abscessus complex（13 strains，18.06%）；resistance to macrolides was detected in 6 cases，while no resistance to aminoglycosides was found. It took 9 to 45 days for BALF MGIT 960 culture to identify NTM，and took 7 to 15 days for NTM typing and drug sensitivity testing. By BALF MGIT 960 culture，28 NTM strains were identified；and 1 case was found to be resistant to macrolides. Using confirmed diagnosis as the gold standard，MALDI-TOF MS demonstrated higher sensitivity，negative predictive value，and agreement rate compared to MGIT 960 culture（84.85% vs. 42.42%，81.13% vs. 56.32%，80.49% vs. 62.60%， χ2=25.667，8.998，9.664， P<0.05 or <0.01）. The area under ROC curve（AUC）for MALDI-TOF MS was significantly higher than that of MGIT 960 culture（0.801 vs. 0.642， Z=3.300， P=0.001）. Conclusion:Compared to MGIT 960 culture，MALDI-TOF MS exhibits superior diagnostic efficiency in detecting NTM pulmonary disease in patients with acid-fast bacilli smear-negative sputum，with advantage of rapidly identifying NTM species and resistance.

Objective:To study the effect of Helicobacter pylori (HP) infection on the standardized dose of postoperative thyrotropin suppression of differentiated thyroid carcinoma.Methods:A total of 82 patients diagnosed with differentiated thyroid carcinoma and receiving total thyroidectomy in Beijing Rehabilitation Hospital affiliated to Capital Medical University from Jan. 2019 to Jun. 2020 were enrolled in this study prospectively.19 patients with higher standardized dose of the thyrotropin suppression (>2.5 μg·kg -1·d -1) were selected as the experimental group, and 63 patients with the lower standardized dose of the thyrotropin suppression (≤2.5 μg·kg -1·d -1) were selected as the control group. The presence of HP infection was measured by C13 method, and the HP infection rate was compared between the two groups. The patients with HP infection in the experimental group received standard quadruple therapy to eradicate Helicobacter pylori. The standardized dose before and after treatment were observed and compared. Results:The HP infection rate in the experimental group (73.7%, 14/19) were significantly higher ( P<0.05) than those in the control group (31.7%, 20/63). In the experimental group, 14 patients with HP infection in the experimental group received standard quadruple therapy to eradicate HP. HP was successfully eradicated in 11 patients after the treatment (one patient quit the treatment before completion, the actual eradication rate was 84.6%) ; Eight weeks after the treatment, the dose adjustment of thyrotropin suppression reached steady-state in 13 patients completed the therapy. The average standardized dose was (2.15±0.25) μg·kg -1·d -1, significantly lower than that before treatment [ (2.89±0.21) μg·kg -1·d -1] ( P<0.05) . Conclusions:HP infection may be an important factor affecting the standardized dose of thyrotropin suppression in postoperative patients with thyroid cancer. For those patients with HP infection, eradication treatment of HP can significantly reduce the standardized dose and treatment-related complications.

Objective:To investigate the efficiency, safety and complication of 0.7 mg dexamethasone sustained release agent (Ozurdex ?) vitreous cavity implantation for macular edema secondary to vitrectomy. Methods:A total of 15 patients (16 eyes) were included in this retrospective case series study. There were 7 males (8 eyes) and 8 females (8 eyes). Age ranged from 47 to 72 years old with an average age of (60.2±8.6)years. Among them, 8 cases were diabetic retinopathy (6 cases combined cataract surgery). 4 cases were silicone oil removal after retinal detachment surgery (all combined cataract surgery). 2 cases were epi-macular membrane (all combined with cataract surgery) and 1 case was vitreous hemorrhage (combined with cataract surgery). Ozurdex ? was implanted for macular edema after vitrectomy. The number of implantation was from 1 to 3 times (mean 1.67 times). The follow-up time was from 3 to 12 months, with an average of (7.33±3.50)months. Results:The best corrected visual acuity (BCVA) was improved in 10 cases (11 eyes), unchanged in 4 cases and decreased in 1 case within 3 months after Ozurdex ? implantation in the 15 cases (16 eyes). The macular edema was significantly improved in all cases. The central macular thickness (CMT) measured by optical coherence tomography (OCT) was from 350 to 1 370 γm before surgery with average thickness (621.60±235.48)γm, and the CMT postoperative was 118 to 556 γm with average thickness (269.87±118.14)γm, with statistically significant difference ( P<0.001). Cataract was not progressive after Ozurdex ? implantation. Macular edema was recurrent in 7 cases after first implantation and stable for additional 1-2 injections. Intraocular pressure elevation occurred in 3 cases 1 to 2 months after implantation with the highest intraocular pressure of 36 mmHg, which were controlled by local anti-glaucoma eye drops. Drugs entered into the anterior chamber in 2 cases and was taken out in 1 case. Conclusions:The efficiency of Ozurdex ? vitreous cavity implantation is definite and the complications are controllable, so it is a safe and effective method to treat macular edema after vitrectomy.
