Objective To observe and analyze the risk factors of secondary intraocular hypertension in diabetic macular edema (DME) patients after treatment with dexamethasone vitreous cavity implant (DEX). MethodsA retrospective observational study. A total of 352 patients with type 2 diabetes mellitus (T2DM) secondary macular edema diagnosed by ophthalmic examination and treated with DEX in Department of Ophthalmology of Harbin 242 Hospital from January 2016 to March 2022 were included in the study. Among them, 221 were males and 131 were females, with the mean age of (55.56±8.09) years. There were 194 patients with disseminated macular edema, 158 patients with cystoid macular edema. All patients underwent vitreous cavity implantation of DEX. Intraocular pressure (IOP) was measured once a month for 3 months after treatment, with IOP over than 25 mm Hg (1 mm Hg=0.133 kPa) or higher than 10 mm Hg from baseline as secondary intraocular hypertension. The relevant clinical data were collected, and the risk factors of secondary intraocular hypertension in DME patients after DEX treatment were analyzed by binary logistic regression. ResultsAmong 352 patients, 116 patients (32.95%, 116/352) were in the intraocular hypertension. Among them, 29 patients (25.00%, 29/116), 69 patients (59.48%, 69/116) and 18 patients (15.52%, 18/116) occurred intraocular hypertension at 1, 2 and 3 months after treatment, respectively. Compared with the normal IOP group, the IOP in the intraocular hypertension group increased significantly at 1, 2 and 3 months after treatment, with statistical significance (t=10.771, 21.116, 13.761; P＜0.001). Compared with normal IOP group, the patients in the intraocular hypertension group had younger age (t=6.967), longer duration of diabetes (t=5.950), longer axial length (AL) (t=14.989), higher proportion of DME grade 3 (Z=6.284), higher proportion of DEX implantation in pars plana (χ2=23.275), and higher HbA1c level (t=10.764), the differences were statistically significant (P＜0.05). Logistic regression analysis showed that longer AL [odds ratio (OR)=1.428, 95% confidence interval (CI) 1.054-1.934], DEX implantation in pars plana (OR=1.358, 95%CI 1.063-1.735), and higher HbA1c (OR=1.702, 95%CI 1.225-2.366) were the risk factors for secondary intraocular hypertension in DME patients after DEX treatment (P＜0.05), older age was a protective factor (OR=0.548, 95%CI 0.380-0.789, P＜0.05). ConclusionsLong AL, DEX implantation in pars plana and high HbA1c are the risk factors for secondary intraocular hypertension after DEX treatment in DME patients, older age is a protective factor.

Conclusion The training modes require that: a) specific plans and schemes; b) unified organization to integrate educational resources effectively; c) reasonable arrangement of implementation process, and d) innovation of training methods and contents to fully play the role of general hospitals and universities; and well control and feedback to promote the integration and perfection of training modes.
cardiac rehabilitation has evolved over the past decades from a simple monitoring for the safe return to physical activities to a multidisciplinary approach that focuses on patient education, individually tailored exercise training, modification of the risk factors and the overall well-being of the cardiac patients. It has been proven to be an effective tool for the care of the patients with heart disease. Recent research in cardiac rehabilitation has demonstrated that tremendous benefits can be derived from the optimal use of cardiac rehabilitation in patients with various cardiac pathologies including ischemic heart disease, heart failure and post heart surgery. The benefits of cardiac rehabilitation include mortality reduction, symptom relief, reduction in smoking and improved exercise tolerance, risk factors modification and the overall psychosocial wellbeing. Unfortunately, cardiac rehabilitation remains considerably underutilized mainly because of referral problems and poor enrollment. The development of alternate approaches and the use of transtelephonic and other means of monitoring and surveillance will help expand the utilization of cardiac rehabilitation.
ObjectiveTo compare the efficacy of subtotal parathyroidectomy(sPTX) and total parathyroidectomy (tPTX) plus parathyroid autotransplantation(AT) in treatment of secondary hyperparathyroidism(SHPT). MethodsClinical data of 76 cases of uremia SHPT who underwent sPTX(n=19) and tPTX+AT(n=57) in Xinjiang Armed Police Corps Command Military Hospital and The Xinjiang Uygur Autonomous Region People's Hospital were retrospectively analyzed(from Feb. 2005 to Sep. 2012). ResultsOf the 76 cases, 68 cases(89.5%) got successful surgery and 8 cases (10.5%) suffered non-complete resection, all cases had relief on bone pain, and 14 cases had relief on pruritus(26.9%, 14/52). The values of serum calcium on 1 day, 7 days, and 6 months after operation were lower in tPTX+AT group (P<0.05), and value of iPTH in 6 months after operation was lower too(P<0.05). The operation time, blood loss, hospital stay, and hospital cost in tPTX+AT group were all higher or longer(P<0.05). All of the 76 cases were followed up for 6-18 months(the median time was 8.7 months). During the followed-up, 2 cases died and 2 cases recurred in tPTX+AT group, 1 case died and 7 cases recurred in sPTX group, that the recurrence rate was higher in sPTX group (P<0.05). ConclusiontPTX+AT has lower recurrence rate, but with longer operation time and hospital stay, more blood loss, and expensive cost, so the choice of surgery for SHPT should be based on the comprehensive situation.
ObjectiveTo investigate the value of MRI in the diagnosis of central nervous system lymphoma (CNSL). MethodsWe retrospectively analyzed the clinical data of 20 cases of primary CNSL (PCNSL) and 13 cases of secondary CNSL (SCNSL) from the Second People's Hospital of Chengdu and Chengdu 363 Hospital from January to December 2013, and analyzed their clinical data and MRI image data. We observed the tumor location, tumor size and signal, and carried out the statistical analysis. ResultsTwenty patients had PCNSL in the brain, including single lesion in 9 (45.0%), and multiple in 11 (55.0%). Among the 48 lesions, there were 23 (47.9%) nodular lesions, 21 (43.8%) crumb lesions, and 4 (8.3%) dot patch lesions; MRI showed slightly low T1 signal and slightly high T2 signal in most lesions, and showed significant even enhancing, and mild to moderate edema around the tumor. SCNSL lesions were mainly meningeal disseminated with 3 cases (23.1%) of single lesions and 10 cases (76.9%) of multiple ones, and there were a total of 30 lesions. MRI manifested that T1 and T2 mainly showed equal signals, and showed an obviously even enhancing status, and mild to moderate edema around the tumor. ConclusionThe central nervous system lymphoma has a certain characteristic MRI image, and MRI images of the primary and secondary central nervous system lymphoma were similar.
Secondary and tertiary hyperparathyroidism are common complications in patients with chronic kidney disease, especially in end stage renal disease. Surgery is an important method for the treatment of secondary and tertiary hyperparathyroidism. The American Association of Endocrine Surgeons Guidelines for the Definitive Surgical Management of Secondary and Tertiary Renal Hyperparathyroidism is the first evidence based guideline focus on renal hyperparathyroidism surgical management. Recommendations using the best available evidence by a panel of 10 experts in secondary and tertiary renal hyperparathyroidism constructed this guideline, which provides evidence-based, individual and optimal surgical management of secondary and tertiary renal hyperparathyroidism. This paper made a guideline interpretation on the indications of surgery, imaging examination, preoperative and perioperative management, relevant evaluation and treatment during perioperative period, and intraoperative parathyroid hormone monitoring during operation, and so on.
Twenty-three patients (28 extremities) suffering secondary ulcer after high ligation and stripping of great saphenous vein were chosen to receive muscle flap formation of potiteal vein. Of which, 21 patients (25 extremities) ulcer scabbed within one week and healed in 2 weeks after operation. The other s were cured in 5 weeks. All patients were followed up 6-12 months with no recurrence and satisfactory results.
ObjectiveTo study the brain tissue oxygen and prognosis index of the postoperative patients with hypertensive intracerebral hemorrhage (HICH) associated with secondary brain insults. MethodsA total of 120 patients with HICH from January 2006 to June 2013 were treated by neurosurgical intervention. Postoperative monitoring of factors affecting the secondary brain insults in the 120 patients and of brain tissue oxygen in 10 patients was performed and statistically analysis was carried out. ResultsSecondary brain insults had a significant influence on the prognosis of postoperative patients with hypertensive intracerebral hemorrhage, and was correlated with brain tissue oxygen metabolism. ConclusionAbnormal secondary brain insults affect brain tissue oxygen metabolism, which may further deteriorate the brain damage and can lead to poor prognosis.
Objective To study the diagnosis and treatment of portal hypertension in secondary biliary cirrhosis(PHSBC). MethodsTwenty-five cases of PHSBC within recent 16 years in our hospital were analyzed. Their clinical, pathological and follow-up data were reviewed retrospectively. They were divided into 4 groups according to their primary diseases:13 patients with hepatolithiasis, 6 with postoperative stricture of biliary duct, 4 with malignancy of biliary duct and 2 with others.Results All patients were diagnosed clinically, and 4 were further pathologically confirmed. Eight cases were treated conservatively, while the remaining 17 underwent operations according to their primary diseases, and one combined with splenectomy and esophagogastric devascularization. The rate of discharge with improvement by surgical and non-surgical treatment was 64.7% and 37.5%, and hospital mortality was 17.6% and 12.5% respectively. Conclusion The diagnosis of PHSBC mainly depends on its characteristic clinical manifestations. The early surgical resolution of bile duct obstruction is the key to good prognosis. If complicated with rupture and hemorrhage of oesophagofundal varices, the surgical procedure should be considered carefully.
