RESUMO
Objective:To analyze the clinical characteristics of nail involvement in patients with pemphigus and the correlation between nail damage and the severity of pemphigus.Methods:The clinical data of 23 patients with pemphigus combined with nail damage admitted to the People′s Hospital of Xinjiang Uygur Autonomous Region from January 2011 to August 2019 were retrospectively analyzed, the manifestations of pemphigus combined with nail damage were summarized. The nail damage number of patients with pemphigus complicated with nail damage of different genders were analyzed, as well as the distribution of nail damage in nail and toenail. The titer of anti-desmocoglycoprotein(dsg) antibody was detected in all patients. The relationship between nail damage and disease severity and course in pemphigus patients was analyzed.Results:A total of 132 damage nails were found in 23 patients (14 males and 9 females) with pemphigus, including 66 nails in male, 66 nails in female, 82 nails and 50 toenails. There were 10 forms of nail damage, of which chronic paronychia was the most common. The number of damage nails between different genders in pemphigus patients was statistically significant (χ 2=9.183, P<0.001). The distribution of nail and toenail damage in pemphigus patients was statistically significant (χ 2=10.880, P<0.001). Of the 23 patients, only 3 were positive for dsg1 and 1 was positive for dsg3. There were 19 patients with both positive for dsg1 and dsg3. The titers of dsg1 and dsg3 were compared in 14 patients before and after nail damage. The results showed that the titers of anti-dsg antibody in pemphigus patients after nail damage were significantly higher than before. Thirteen of the 23 patients had nail damage at the time of the initial onset of pemphigus. The nail damage occurred from 6 weeks before the onset to 4 weeks after the onset. The nail damage occurred in 10 patients when the disease recurred. The nail damage occurred within 4 weeks before or at the same time with the blister. Conclusions:The number of damage nails per capita in female patients with pemphigus and nail damage was significantly higher than that in male patients, and nail damage was more common. The titers of anti-dsg antibody will be at a high level when pemphigus patients with nail damage, and the condition gets worse. Nail involvement is positive to the severity of the disease, and it can prolong the time of disease.
RESUMO
Objective:To investigate the influence of echinoside on the expressions of inducible nitric oxide synthase (iNOS) and transforming growth factor-β1 (TGF-β1) in renal tissues of diabetic nephropathy rats.Methods:A total of 60 male SD rats were randomly divided into the normal group, model group, glibenclamide group and low-, medium-, high-dose echinoside treatment group. the rat model of diabetic nephropathy was established through the streptozocin induction and the glibenclamide treatment was applied as control. After molding, glibenclamide group was given 5 mg/(kg?d) of glibenclamide, and low-, medium-, high-dose echinoside treatment group was given 50, 100 and 200 mg/(kg?d) of echinacoside solution. The normal group and model group were intragastrically given equal volume of normal saline. After 4 weeks, the change rate of body weight, kidney weight/body weight, blood glucose, serum TC, TG, BUN, SCR and 24 h urinary protein levels were measured, and the NO release concentration in renal tissue cell culture medium was measured, the renal pathology was observed by HE staining, the expression of iNOS and TGF-β1 proteins in renal tissues was detected by Western blotting.Results:Compared with the model group, the body weight of rats in the medium-dose group significantly increased ( P<0.05); the weight change rate and kidney weight/body weight of rat in the medium-, high-dose group significantly decreased ( P<0.05), and the NO release concentration in the medium-, high-dose group decreased ( P<0.05); the level of blood glucose, TC, TG, BUN, SCr, and 24-hour urinary protein in the low-, medium- and high-dose groups significantly decreased ( P<0.05), and iNOS in renal tissue of rats in the low-, medium- and high-dose groups was significantly lower ( P<0.05). Compared with the model group, the relative expression levels of TGF-β1 (1.35 ± 0.06, 1.15 ± 0.05, 0.91 ± 0.04 vs. 4.58 ± 0.09) and TGF-β1 (1.24 ± 0.04, 1.41 ± 0.05, 0.89 ± 0.04 vs. 3.04 ± 0.05) in the low-, medium- and high-dose groups significantly decreased ( P<0.05). Conclusions:The echinoside can prevent weight loss, reduce blood glucose and triglyceride, inhibit the production of NO in renal tissues, reduce the expression of iNOS and TGF-β1 among diabetic nephropathy rats. It has been proved to play a protective role in diabetic nephropathy pathological tissues.
RESUMO
Objective To explore the effects of Living with Hope Program(LWHP) on family caregivers of patients with advanced lung cancer.Methods Totally 60 family caregivers of patients with advanced lung cancer were randomly divided into the experimental group and the control group.The experimental group received LWHP intervention and routine care knowledge education,the control group only received routine care knowledge education.Hope,self-efficacy,anxiety and depression,and quality of life were evaluated at the first week,the second week,the first month,and the third month.Differences between two groups were compared using variance analysis of repeated measurements.Results The self-evaluation of the intervention was 76.6％,and the main effects of hope level,selfefficacy,anxiety and depression,and mental health were statistically significant (P＜0.05);the time effect on hope level and self-efficacy were statistically significant (P＜0.05);there were interaction effects between intervention and time on hope level,self-efficacy,anxiety and depression,and mental health (P＜0.05).Conclusion LWHP can effectively improve hope level,self-efficacy and mental health status,and alleviate anxiety and depression of family caregivers of patients with advanced lung cancer.
RESUMO
<p><b>OBJECTIVE</b>Dust sample mass gain is too smaller to satisfy the limit of detection (LOD) even in most cases during dust sampling at workplaces nowdays, especially for respirable fraction. Therefore, it is aimed to solve the problem by increasing sample load with high flow rate samplers.</p><p><b>METHODS</b>In A and B two shipyards respirable welding fume was sampled by high flow rate cyclone samplers of FSP-10 (10 L/min) for 2-2.5 hours and normal flow rate FSP-2 (2 L/min) for 3-4 hours with a stratigy of parallele sampling at the same workpalce, in order to compare their mass gain, coincidence rate with LOD, and airborn dust concentration.</p><p><b>RESULTS</b>Sample mass gain of 0.97±0.40 mg and 1.61±0.86 mg respectively in the two factories by FSP-10 was significantly higher than that of 0.29±0.12 mg and 0.51±0.27 mg by FSP-2 (t-test, P<0.05 in both cases) , increasing herewith the coincidence rate with LOD from 26.8% (when sampling with FSP-2, calculated together with samples of the two factories) to 89.7%. However there was no significant difference in dust concentrations by the two different samplers, 0.53±1.88 vs 0.73±1.61 mg/m(3) by FSP-2 and FSP-10 in the shipyard A and 1.14±1.78 vs 1.01±1.63 mg/m(3) in the factory B (t-test, P>0.05 in every case) . In addtion, sample loading by FSP-2 was found to be correlated to sampling time (R(2)=0.7906, y=0.002 6x) , therefore, it has to sample for ≥192.3 min to meet the LOD (0.5 mg) in case of normal flow rate.</p><p><b>CONCLUSION</b>By using of high flow rate cyclone FSP-10 the problem of LOD could be solved, along with increased sample mass and similar respirable dust concentration by the two samplers. Some techincal improvements of FSP-10 and increasing of LOD coincidence rate by other methods was also disscussed.</p>
