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.

BACKGROUND: Human allogenic acellular dermal matrix, as a kind of permanent dermal scaffold, has widely used in the fields of burn wound reparation and aesthetic medicine. However, it is limited due to insufficient resources. OBJECTIVE: To prepare porcine acellular dermal matrix (PADM) dermal matrix, in addition, to estimate its in vitro biocompatibility. DESIGN, TIME AND SETTING: An in vitro cytology contrast experiment. The Experiment was performed at the laboratory of Biomaterials and Pharmacy Technology Institute, China Institute for Radiation Protection between August 2007 and June 2008. MATERIALS: The experiment pigs were supplied by experimental animal center of China Institute for Radiation Protection. Human fibroblasts were obtained from prepuce tissues of healthy children who underwent circumcision at the Shanxi Provincial General Hospital, Chinese People's Armed Police Forces. METHODS: The PADM was prepared from porcine skin by removing epidermis with a hypertonic salt solution and excluding cellular components in dermis with sodium dodecyl sulfate, and trypsin in hypersonic conditions. Human fibroblasts were cultured in vitro, and the biocompatibility of PADM was estimated with MTT method and contact method. MAIN OUTCOME MEASURES: ①Histological morphology of PADM. ②In vitro biocompatibility of PADM. RESULTS: The prepared PADM was a kind of matrix with normal structure and organization of collagen without epidermis and any cellular components in the dermis. The extraction of the porcine acellular dermal matrix had no effect on proliferation of the cultured human fibroblast. The cultured human fibroblasts could attach and proliferate on PADM. CONCLUSION: The PADM effectively removed epidermis and all cellular components with excellent biocompatibility can be obtained by this preparation method.

Objective To investigate the risk factors of hemorrhagic transformation (HT) following thrombolytic therapy in acute cerebral infarct patients. Methods The clinical data of 246 cases with acute cerebral infarct treated with rt-PA within 4.5 h from the onset were reviewed. According to the results of brain CT imaging after intravenous thrombolysis for 24-36 h, the patients were divided into HT group and non HT group. The factors including age, gender, NIHSS scores, drinking, smoking, hypertension, diabetes, atrial fibrillation. The univariate analysis and Losgistic regression analysis were further assessed. Results The results of univariate analysis indicated that there were no significant differences between the two groups in age, gender, smoking , drinking, time from onset to thrombolysis, diabetes (P > 0.05), but there were significant differences between two groups in NIHSS scores [(14.53 ± 6.06) scores vs.(9.98 ± 6.26) scores, P = 0.000], hypertension [86.1%(31/36) vs.70.0%(147/210), P = 0.046] and atrial fibrillation [63.9%(23/36) vs. 24.3%(51/210), P = 0.000]. Logistic regression analysis showed that NIHSS scores (OR = 1.079, 95% CI = 1.014- 1.147, P = 0.016) and atrial fibrillation (OR=3.298, 95%CI=1.481-7.345, P=0.003) were the risk factors associated with hemorrhagic transformation after intravenous thrombolysis for acute cerebral infarction. Conclusions NIHSS scores and atrial fibrillation are the risk factors associated with HT after thrombolytic therapy in acute cerebral infarct patients.

Objective To investigate the clinical value of cardiopulmonary resuscitation (CPR) with abdominal lifting and compression on patients with breathing and cardiac arrest induced by severe chest trauma.Methods Sixty-six breathing and cardiac arrest patients induced by severe chest trauma admitted to the General Hospital of Jingyuan Coal Industry Group Company from October 2011 to October 2016 were enrolled,and they were divided into abdominal lifting and compression group (n =32) and unarmed abdominal compression group (n =34) by random number table.The patients in both two groups were given the airway open,respiration support,defibrillation treatment,venous access establishment,vasoactive drugs application and other conventional treatments.On the basis of the routine treatment,the patients in abdominal lifting and compression group were given application of abdominal lifting and compression device with 100 times/min frequency and continuously alternating press down to lift the abdomen,the amplitude of pressing and pulling were 3-5 cm below or above the original level of the abdomen.Those in unarmed abdominal compression group were given abdominal CPR pressing method by hand,the frequency of pressing and depth of subsidence was the same as abdominal lifting and compression group.Heart rate (HR) and arterial blood gas at 30 minutes after CPR as well as the success rate of resuscitation were compared between the two groups.The changes in HR,mean arterial pressure (MAP) and pulse oxygen saturation (SpO2) before and 30 minutes and 60 minutes after CPR were dynamically observed in patients with restoration of spontaneous circulation (ROSC) after abdominal lifting and compression CPR treatment.Results Compared with the unarmed abdominal compression group,HR (bmp:136.13±6.14 vs.148.45±5.16) and arterial partial pressure of carbon dioxide [PaCO2 (mmHg,1 mmHg =0.133 kPa):48.51 ±2.60 vs.62.51 ±2.50] at 30 minutes after CPR in abdominal lifting and compression group were significantly lowered,and arterial partial pressure of oxygen (PaO2) was significantly increased (mmHg:88.07±3.92 vs.74.12±2.12,all P ＜ 0.05).Four patients with ROSC were found in abdominal lifting and compression group,and 2 in unarmed abdominal compression group.The success rate of resuscitation in abdominal lifting and compression group was significantly higher than that of unarmed abdominal compression group (12.50％ vs.5.82％,P ＜ 0.05).In 4 patients with ROSC after abdominal lifting and compression CPR showed a downward trend in HR and an upward trend in MAP and SpO2 with CPR time prolongation.Conclusions The effect of abdominal lifting and compression CPR is better than that of unarmed abdominal compression CPR,which is of great value for the life saving of patients with breathing and cardiac arrest induced bv severe chest trauma.

Objective To investigate the risk of hemorrhagic transformation and the curative effect in patients with atrial fibrillation(AF)treated by intravenous thrombolysis with alteplase after acute cerebral infarct. Methods The clinical data of 246 patients with acute cerebral infarct treated with intravenous alteplase within 4.5 h from the onset were analyzed.According to the presence or absence of AF, the patients were divided into AF group (74 cases) and non AF group (172 cases). The outcomes were the incidence of hemorrhagic transformation within 36 h and the curative effect after 2 weeks. Results The incidence of hemorrhagic transformation in AF group was 31.1%(23/74), in non AF group was 7.6%(13/172),and there was significant difference(χ2=22.917,P=0.000).The effective rate in AF group was 54.1%(40/74), in non AF group was 76.7%(132/172), and there was significant difference (χ2=12.665,P=0.000).Conclusions Patients with acute cerebral infarction combined with AF have a high risk of hemorrhagic transformation and poor prognosis after intravenous thrombolysis.

Short-lasting unilateral neuralgiform headache attacks with conjunctival injection and tearing (SUNCT) is a primary headache syndrome with an unclear pathogenesis. However, there is increasing evidence in the literature for secondary SUNCT being attributable to certain known lesions. We explored the possible neurobiological mechanism underlying SUNCT based on all reported cases of secondary SUNCT for which detailed information is available. Here we report a case of neuromyelitis optica spectrum disorders that had typical symptoms of SUNCT that might have been attributable to involvement of the spinal nucleus of the trigeminal nerve. We also review cases of secondary SUNCT reported in the English-language literature and analyze them for demographic characteristics, clinical features, response to treatment, and imaging findings. The literature review shows that secondary SUNCT can derive from a neoplasm, vascular disease, trauma, infection, inflammation, or congenital malformation. The pons with involvement of the trigeminal root entry zone was the most commonly affected region for inducing secondary SUNCT. In conclusion, the neurobiology of secondary SUNCT includes structures such as the nucleus and the trigeminal nerve with its branches, suggesting that some cases of primary SUNCT have underlying mechanisms that are related to existing focal damage that cannot be visualized.
