ABSTRACT

Objective:The purpose of this study was to examine the clinical features and initial treatment outcomes of elderly individuals with idiopathic membranous nephropathy.Methods:This study retrospectively analyzed the clinical characteristics and therapeutic effect of hospitalized patients aged 60 years or older with renal-biopsy-proven idiopathic membranous nephropathy for at least one year.Results:This study enrolled a total of 91 elderly patients with IMN, consisting of 51 males(56.0%)and 40 females(44.0%). The median age of the patients was 67 years.The urinary protein creatinine ratio(uPCR)and urinary albumin creatinine ratio(uACR)of the patients were 4 454.3 mg/g and 2 258.5 mg/g, respectively.The median 24-hour urinary protein and urinary albumin levels were 5 098.2 mg/24 h and 2 800.6 mg/24 h, respectively.The average estimated glomerular filtration rate(eGFR)was(60.5±20.4)ml·min -1·1.73 m -2.Out of the total of 61 patients, 67.0% achieved remission, including complete and partial remission, within a year of renal biopsy.The levels of uPCR and uACR were significantly higher in the non-remission group compared to the remission group(5 462.5 vs.2 271.1 mg/g, P<0.001; 2 774.4 vs.1 320.0 mg/g, P=0.001). Additionally, the levels of 24h urinary protein and urinary albumin were significantly higher in the non-remission group compared to the remission group(6 526.4 vs.3 210.4 mg/g, P=0.002; 3 067.7 vs.2 102.4 mg/g, P=0.007). The remission group had a higher proportion of patients receiving immunosuppressive therapy(85.2% vs.33.3%, P<0.001). The remission rates were higher in patients treated with glucocorticoid combined with cyclophosphamide, glucocorticoid combined with calcineurin inhibitors, or glucocorticoid combined with mycophenolate mofetil compared to those receiving conservative treatment(88.2% vs.31.0%, P=0.001; 80.0% vs.31.0%, P<0.001; 100.0% vs.31.0%, P=0.007). There was no significant difference in remission rate between the three immunosuppressive therapy groups( P>0.05). However, upon further analysis, it was found that the levels of uPCR, uACR, and serum cystatin C(CysC)were higher in the immunosuppressive therapy groups compared to conservative treatment.Additionally, serum total protein and albumin were lower in the immunosuppressive therapy groups, and these differences were statistically significant( P<0.05). Conclusions:The majority of elderly patients diagnosed with IMN have multiple comorbidities.For those at high risk with elevated urinary protein levels, early initiation of immunosuppressive therapy may lead to a higher initial urinary protein remission rate.Therefore, it is advisable to develop individualized treatment plans for elderly patients with IMN based on their clinical characteristics, as well as the risks and benefits associated with immunosuppressive therapy.

ABSTRACT

Objective To investigate the articles on liver diseases published by authors from China (excluding Hong Kong, Macao, and Taiwan regions) in Gastroenterology & Hepatology journals indexed in Science Citation Index Expanded (SCIE) in 2016-2020, to analyze the bibliographic and citation data of these articles, and to understand the contribution and impact of Chinese scholars in the field of liver disease research in recent years. Methods The data for bibliometric analysis came from the SCIE database and Journal Citation Reports (JCR). The SCIE database was searched for the journal articles published in JCR Gastroenterology & Hepatology journals in 2016-2020, with a title or abstract containing "Liver", "Hepatocellular", "Hepatitis", "Cirrhosis", or "Hepatic" and a publication type of Article. Clinical guidelines were excluded, and the records with the corresponding author's affiliation containing institutions in China (excluding Hong Kong, Macao, and Taiwan regions) were screened out. R package bibliometrix was used to calculate the frequency of citations of included articles by liver disease studies published by Chinese and global authors in the Gastroenterology & Hepatology journals in 2016-2020, and R package DescTools was used to perform the Cochran-Armitage trend test to observe the change in composition ratio. Results In the Q1 Gastroenterology & Hepatology journals in 2016-2020, liver disease studies published by Chinese authors accounted for 9.5%. In recent years, the proportion of liver disease studies published by Chinese authors in Q1 Gastroenterology & Hepatology journals continues to increase from 6.0% to 12.2% ( P < 0.001). Among the liver disease studies published by Chinese authors in Q1 Gastroenterology & Hepatology journals, 79.7% were funded by National Natural Science Foundation of China, and there was no significant change in the proportion of studies funded by National Natural Science Foundation of China and published by Chinese authors in each partition of Gastroenterology & Hepatology journals in 2016-2020. The frequency of citations of included articles by liver disease studies published by Chinese and global authors in the Gastroenterology & Hepatology journals showed that liver disease studies published by Chinese authors had a high impact in both domestic and international academic communities. Conclusion In recent years, there has been a constant increase in the number of liver disease studies published by Chinese authors in high-impact Gastroenterology & Hepatology journals indexed in SCIE, and most of these studies have been funded by National Natural Science Foundation of China. The liver disease studies published by Chinese authors in Gastroenterology & Hepatology journals have been widely recognized by domestic and international academic communities.

ABSTRACT

Objective:To observe the results of electroacupuncture (EA) on the resuscitation of a rat model of asphyxia cardiac arrest (CA). And to explore its effect on the neurologic deficits and hemodynamic instability of post-cardiac arrest syndrome (PCAS).Methods:A total of 107 male SD rats were randomly divided into sham, CA, and EA groups. Each group received arterial catheterization and tracheal intubation. The sham group was not induced asphyxia. Asphyxial cardiac arrest was established by endotracheal tube clamping. Rats in the CA group received basic respiratory support and fluid resuscitation in return of spontaneous circulation (ROSC) and rats in the EA group received EA at Baihui based on the treatment of CA group after ROSC, with a dense-dispersed wave at frequencies of 4-20 Hz, while the current intensity was adjusted minimum to induce a twitch of the scalp, the course of treatment was 30 minutes. The baseline data, hemodynamics after ROSC, neurological deficit score (NDS), pathological changes of brain tissue, and levels of serum biomarker were recorded and compared among the three groups. The 72-hour survival of rats was analyzed by Kaplan-Meier survival curve. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of necrotic neurons in the hippocampal CA1 region of rat brain. Meanwhile, Nissl staining and TdT-mediated dUTP nick-end labeling (TUNEL) were used to detect cell apoptosis and injury.Results:Compared with the CA group, the mean arterial pressure (MAP) in the EA group increased significantly at 15 minutes after ROSC [mmHg (1 mmHg≈0.133 kPa): 125.00 (94.00, 136.25) vs. 92.00 (72.00, 122.50), P < 0.05]. There was no significant difference in the NDS score between the EA group and the sham group. Still, the NDS score of the rats in the CA group at 6 hours after ROSC were significantly lower than that in the sham group (46.00±10.61 vs. 80.00±0.00, P < 0.05). Kaplan-Meier survival curve analysis showed that EA did not improve the 72-hour survival rate of rats (100% in the sham group, 25% in the CA group, and 30% in the EA group, P > 0.05). The analysis by TUNEL showed that the apoptosis rate of neurons in CA1 region of the hippocampus in EA group at 6 hours after ROSC was significantly lower than that in CA group [(62.84±2.67)% vs. (71.29±3.70)%, P < 0.05]. Compared with the CA group, the level of serum S100 calcium binding protein B (S100B) in the EA group at 6 hours after ROSC was significantly lower (ng/L: 19.30±13.87 vs. 132.28±31.67, P < 0.05), but there were no significant differences in the levels of tumor necrosis factor-α (TNF-α) and interleukin-6 (IL-6) between these two groups. Conclusions:In the present study, EA at Baihui can stabilize the hemodynamic, moreover, it has a particular neuroprotective effect on PCAS rats. Still, EA at Baihui does not reduce the systemic inflammatory response and improve the survival rate of rats, and its mechanism remains to be verified in further research.

ABSTRACT

ObjectiveTo investigate the value of red blood cell distribution width-to-platelet ratio (RPR), platelet-to-lymphocyte ratio (PLR), and neutrophil-to-lymphocyte ratio (NLR) in predicting chronic hepatitis C (CHC)-related compensated liver cirrhosis by comparing serological markers between CHC patients and patients with compensated hepatitis C cirrhosis. MethodsThe patients with CHC in two townships of Fuyu County were screened for liver cirrhosis and liver cancer from September to December in 2019 and 2020, respectively. General information was collected; HCV RNA quantification, liver function, and routine blood test results were measured; liver transient elastography and abdominal ultrasound were performed at the same time. RPR, PLR, NLR, fibrosis-4 (FIB-4), and aspartate aminotransferase-to-platelet ratio index (APRI) were calculated. The Mann-Whiney U test was used for comparison between groups. The chi-square test was used for comparison of categorical data between groups. The receiver operating characteristic (ROC) curve was plotted to determine the optimal cut-off values of RPR and PLR. A multivariate unconditional logistic regression analysis was used to investigate the risk factors for CHC-related liver cirrhosis. The linear regression trend test was used to investigate the changing trend of RPR, PLR, FIB-4, and APRI in hepatitis C patients with different fibrosis stages. ResultsA total of 968 CHC patients were enrolled, among whom 123 (12.7%) were diagnosed with compensated liver cirrhosis (liver cirrhosis group). Compared with the CHC group, the liver cirrhosis group had a significant increase in RPR and a significant reduction in PLR (P<0.001). The multivariate logistic regression analysis showed that age >60 years (odds ratio [OR]=1.79, 95% confidence interval [CI]: 1.12-2.86, P=0.015), albumin <40 g/L (OR=1040, 95% CI: 3.47-31.18, P<0.001), RPR >0.081 (OR=3.83, 95% CI: 2.19-6.69, P<0.001), PLR <91.11 (OR=225, 95% CI: 1.31-3.89, P=0.004), FIB-4 >3.25 (OR=3.14, 95% CI: 1.74-5.67, P<0.001), and APRI >2 (OR=360, 95% CI: 110-11.78, P=0.035) were associated with the development of CHC-related compensated liver cirrhosis. With the aggravation of liver fibrosis, RPR, FIB-4, and APRI gradually increased and PLR gradually decreased (all P<0.001). ConclusionRPR and PLR are associated with the development and fibrosis progression of CHC-related compensated liver cirrhosis. Elderly patients with CHC (age >60 years) should be monitored for the changes in albumin and liver fibrosis indicators, and RPR and PLR should also be monitored regularly to identify liver cirrhosis in the early stage, give timely treatment, and reduce the incidence rate of liver cancer.

ABSTRACT

Objective:To examine the concordance between bioelectrical impedance analysis (BIA) and dual energy X-ray absorptiometry (DXA) in determining body composition of children aged between 3 and 6.Methods:A total of 230 children aged 3-6 from a kindergarten in Jinnan, Tianjin were enrolled in this study from November 16 th to December 8 th, 2017.The soft lean mass (SLM) and the body fat mass (BFM) of the children were measured by using BIA and DXA.The children were divided into several groups by sex, age and body mass index (BMI). The consistency of the body composition results between BIA and DXA in each group was analyzed. Results:The SLM and BFM assessed by BIA were significantly correlated with those measured by DXA ( R2=0.951, 0.947, all P<0.001). The Bland-Altman plots suggested that the SLM measured by BIA was 0.70 kg(95% CI: -1.78-0.38) higher in that by DXA, and the BFM measured by BIA was 1.36 kg (95% CI: 0.19-2.52) lower in that by DXA.A similar trend could be seen in children stratified by age, sex and BMI.The SLM of boys and girls measured by BIA was 0.57 kg (95% CI: -1.63-0.49) and 0.84 kg (95% CI: -1.88-0.20) higher than those by DXA, respectively.The BFM of boys and girls measured by BIA was 1.23 kg (95% CI: 0.11-2.36) and 1.49 kg (95% CI: 0.34-2.64) lower than that by DXA, respectively.The SLM measured by BIA was 0.67 kg (95% CI: -1.74-0.41), 0.76 kg (95% CI: -1.65-0.13), 0.69 kg (95% CI: -1.85-0.47) and 0.67 kg (95% CI: -1.75-0.41) higher than those by DXA in the 3 to 6-year-old groups, respectively.The BFM measured BIA was 1.09 kg (95% CI: -0.12-2.30), 1.44 kg (95% CI: 0.60-2.28), 1.39 kg (95% CI: 0.15-2.64)and 1.43 kg(95% CI: 0.38-2.48)lower than that by DXA in the 3 to 6-year-old groups, respectively.Moreover, the smallest difference of the SLM and BFM were observed between BIA and DXA in the obese child.The SLM deviation between BIA and DXA was estimated within ± 0.39 kg and the BFM deviation was within ± 0.93 kg. Conclusions:There is high consistency between BIA and DXA in the assessment of the SLM and BFM of children aged from 3 to 6.

ABSTRACT

Teaching in experiments of biology is important for the cultivation of life science talents. In view of the rapid development of life science and the increasing demand for research-oriented talent training, teaching in experiments of biology should set up a variety of learning outcomes: to train experimental skill, to cultivate students' experimental design and operation abilities, and to improve students' scientific thinking and innovative consciousness. We have carried out an educational reform on experimental genetic engineering blended course. In this paper, we introduced our methods of organizing online materials, the curriculum design of the blended course, the implementation details, and a preliminary analysis of teaching effects. We found that experimental genetic engineering blended course could support students' active learning and a learning-centered teaching model. Moreover, it could facilitate students' achievement of improving experimental skills, cultivating a rigorous scientific attitude, professional research quality and academic innovation ability.

ABSTRACT

Objective:To investigate the effects of pressure gradient controlled carbon dioxide (CO 2) pneumoperitoneum establishment in patients with gynecological laparoscopic surgery on early circulatory and respiratory function. Methods:From November 1, 2018 to March 31,2019,100 case of gynecological laparoscopic surgery who were scheduled to undergo elective surgery in Jiangsu Hospital of Traditional Chinese Medicine were enrolled and divided into experimental group(50 cases) and control group(50 cases) by random number table method. The experimental group used pressure gradient control method to establish CO 2 pneumoperitoneum, that is, the pneumoperitoneum pressure was set to 5, 9, 12 mmHg(1 mmHg=0.133 kPa) gradually rising three gradients, and after reaching the corresponding gradient, they were maintained for 1 minute to 12 mmHg; the control group used conventional method, that was, the pneumoperitoneum pressure was set directly to 12 mmHg, and began to inflate until reaching the preset pressure. Systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), end-of-breath partial pressure of CO 2 (P ETCO 2), peak airway pressure (P peak), arterial blood partial pressure of CO 2 (PaCO 2) and the intervention of cirulation and respiration were compared between the two groups before and within 15 minutes after pneumoperitoneum. Results:The max values of SBP, DBP, MAP, HR, P ETCO 2, Ppeak and PaCO 2 within 15 minutes after pneumoperitoneum in the experimental group were (117.08±13.07) mmHg, (77.08±9.43) mmHg, (90.06±10.33) mmHg, (69.04±9.10) times/min, (36.00±3.37) mmHg, (20.18±2.74) cmH 2O(1 cmH 2O=0.098 kPa), (40.65±3.31) mmHg, higher than that of the control group (140.63±18.34) mmHg, (91.90±11.79) mmHg, (107.25±12.85) mmHg, (77.67±13.57) times/min, (38.31±4.31) mmHg, (24.81±4.26) cmH 2O, (45.19±4.49) mmHg, the differences were statistically significant( t values were-7.269--2.945, all P<0.01). The amplitudes of SBP, DBP, MAP, HR, P ETCO 2, Ppeak and PaCO 2 fluctuations before and after pneumoperitoneum in the experimental group were (10.14±6.34) mmHg, (8.98±5.88) mmHg, (9.14±5.44) mmHg, (5.80±2.48) times/min, (3.27±1.43) mmHg, (2.65±1.54) cmH2O, (4.08±1.74) mmHg, while the control group were (33.65±14.87) mmHg, (26.17±9.73) mmHg, (28.04±9.97) mmHg, (17.63±9.77) times/min, (6.98±2.89) mmHg, (7.44±2.35) cmH 2O, (9.52±3.92) mmHg, the differences were statistically significant( t values were -11.841--8.048, all P<0.01). Within 15 minutes after pneumoperitoneum, circulatory intervention was 4.08% (2/49) in the experimental group, lower than that in the control group 22.92% (11/48), the difference was statistically significant( χ2=7.412, P<0.01). Respiratory intervention in the experimental group was 0 (0/49), lower than that in the control group 10.42%(5/48), the difference was statistically significant(Fisher test, P<0.05). Conclusions:In gynecological laparoscopic surgery, using pressure gradient control method to establish CO 2 pneumoperitoneum is conducive to reducing the effect of early pneumoperitoneum on circulatory and respiratory function, maintaining the relative stability of circulatory and respiratory function, effectively reducing anesthesia-related interventions after circulatory and respiratory fluctuations, and is conducive to the safety of patients.

ABSTRACT

Objective@#To investigate the risk factors of postoperative acute kidney injury (AKI) in patients aged between 40 and 50 years old undergoing cardiac valvular surgery and the impact on outcome.@*Methods@#The clinical data of 286 patients aged between 40 and 50 years old undergoing cardiac valve surgery in Guangdong Provincial People′s Hospital from January 2012 to December 2016 were analyzed retrospectively. Preoperative coronary angiography was performed in all patients. All patients enrolled were divided into AKI group and non-AKI group according to the existence or not of postoperative AKI. Patients with AKI were further divided into AKI stage 1, stage 2, and stage 3 groups according to KDIGO guideline. Demographic characteristics, preoperative clinical data including serum creatinine, estimated glomerular filtration rate, hemoglobin, uric acid, urinary protein, presence or absence of chronic kidney disease, left ventricular ejection fraction, pulmonary artery pressure, New York Heart Association (NYHA) functional classification, preoperative co-morbidity (hypertension, diabetes, anemia, cerebrovascular disease, peripheral artery disease), preoperative medication(vasoactive drugs, diuretic, renin-angiotensin system inhibitor (RASI), surgical data (contrast dosage in coronary angiography, type of cardiac valve surgery) were recorded and analyzed in this retrospective study. The risk factors for postoperative AKI and its impact on clinical outcomes (mortality, hospitalization expenses and Intensive Care Unit stay duration) were evaluated. Logistic regression analysis was used to determine the risk factors for postoperative AKI and the adjusted variables with P<0.2 were selected for the multivariate logistic regression analysis to define the independent determinants for AKI.@*Results@#AKI was defined in 106 out of 286 enrolled patients, including 96 patients with AKI stage 1, 10 patients with AKI stage 2 and no patients with AKI stage 3. The proportion of coexisting cerebrovascular diseases was higher in AKI group than in non-AKI group (9(8.49%) and 5(2.78%), χ2=4.677, P=0.031), while there was no difference among other baseline data between the two groups. Multivariate logistic regression analysis showed that preoperative complications of cerebral vascular disease was an independent risk factor of postoperative AKI (OR=3.578, 95%CI 1.139-11.242, P=0.029). Five out of 106 AKI patients died during hospitalization while there was only 1 patient died among 180 patients without AKI. Patients with AKI after cardiac valve operation experienced higher mortality than patients without AKI (χ2=5.625, P=0.028). Further analysis showed that there was no difference in hospitalization mortality between patients with AKI stage 2 and stage (χ2=0.686, P=0.408) while the hospitalization mortality in patients with AKI stage 2 was higher than those without AKI (χ2=8.113, P=0.004). The hospitalization expenses in patients with AKI were 10.38(8.59,12.54) ×104 RMB, significantly higher than that in patients without AKI (9.72(8.03,11.93) ×104 RMB)(P=0.043). There was no difference in hospitalization expenses between patients with AKI stage 1 and without AKI (P=0.635). The hospitalization expenses in patients with AKI stage 2 was higher than those without AKI (P=0.023). Intensive Care Unit stay duration in patients with AKI was 3(1,4) days, significantly higher than those without AKI (P=0.044). There was no difference in Intensive Care Unit stay duration in patients with AKI stage 1 and without AKI (P=0.978), while Intensive Care Unit stay duration in patients with AKI stage 2 was significantly longer than those without AKI (P=0.006).@*Conclusions@#Preoperative complications of cerebral vascular disease is an independent risk factor of postoperative AKI. Non-senile patients with AKI after cardiac valvular surgery is associated with a higher proportion of mortality, hospitalization expenses and Intensive Care Unit stay duration as compared patients without postoperative AKI.

ABSTRACT

Objective@#To investigate the number and distribution of dendritic cells (DCs), macrophages and M2 macrophages in renal tissues of patients with IgA nephropathy (IgAN) and their correlation with clinicopathological parameters, and explore its role in the progression of IgAN.@*Methods@#Renal tissue samples from 42 patients aged ≥18 years with IgAN were collected by kidney biopsy in Guangdong Provincial People's Hospital from January 2018 to June 2018. The patients were divided into different groups according to Oxford classification and Lee grade classification criteria. The distribution and number of DCs (CD209), macrophages (CD68) and M2 macrophages (CD68 and CD206) were detected by immunohistochemistry. Spearman correlation test was used to analyze the correlation between the number of DCs and macrophages in renal tissues and clinical pathological parameters.@*Results@#The number of DCs in the glomeruli of the M1, T0 and C1 groups increased significantly compared with the M0, T1 and C0 groups, and the number of DCs in the renal interstitium of the T1 group increased significantly compared with the T0 group (all P<0.05). The number of glomerular macrophages in group C1 was significantly higher than that in group C0. The number of macrophages in S1, T1 and Lee IV-V tubulointerstitial groups was significantly higher than that in S0, T0 and Lee II-III groups (P<0.05). The number of M2 macrophages in the S1, T1 and Lee IV-V groups was significantly higher in the tubulointerstitial group than in the S0, T0 and Lee II-III groups (all P<0.05). The blood urea nitrogen, serum creatinine and 24 h urine protein levels in the T1 and Lee IV-V groups were significantly higher than those in the T0 and Lee II-III groups, and the serum albumin levels in the Lee IV-V group were significantly lower (all P<0.05). Spearman correlation analysis showed that the number of DCs in renal interstitium was positively correlated with the proportion of tubulointerstitial fibrosis. There were a positive correlation between the proportion of glomerular segmental sclerosis and tubulointerstitial fibrosis and renal interstitial macrophages and M2 macrophages. The number of M2 macrophages was positively correlated with serum creatinine and 24 h urine protein (both P<0.05).@*Conclusions@#The number of DCs and M2 macrophages in kidneys are positively correlated with the clinicopathological features of IgAN patients, which indicates that they may be associated with disease progression.

ABSTRACT

Objective To investigate the incidence of hyperkalaemia and analyze the risk factors in pa-tients with acute kidney injury(AKI)in cardiology department.Methods We conducted a retrospective case-con-trol study,using the electronic medical information of the patients in Guangdong General Hospital. Results A to-tal of 37 837 patients were included in this study and 1 571(4.3%)patients with AKI were detected.Hyperkalae-mia occurred in 517 patients(1.4%).The incidence of hyperkalaemia in AKI patients was higher than that in non-AKI patients(10.1% vs. 1.0%,P < 0.001)and the incidences of hyperkalaemia at AKI stage 1~3 were 2.6 %, 13.9% and 20.6 %,respectively. Multiple logistic regression analysis demonstrated that AKI stages,chronic kid-ney disease and heart failure were risk factors for hyperkalaemia.AKI and hyperkalaemia were related to increased hospitalization expenses,delayed hospital stay,renal replacement therapy and in-hospital mortality. Based on AKI,the combination of hyperkalemia could significantly increase clinical burden and adverse outcomes. Conclu-sion In cardiology department,the monitoring of serum creatinine and potassium level should be emphasized.

ABSTRACT

Epidemiology shows that the most common psoriasis is psoriasis vulgaris. The common traditional Chinese medicine (TCM) syndrom is the blood-heat type, which is equivalent to the progressing stage of psoriasis. This article summarized the experimental research of TCM in treating psoriasis vulgaris which is considering as the blood-heat type on the basis of the differentiation of symptoms and signs. The mechanism of clinical efficacy on treating psoriasis vulgaris which is at the blood-heat type was explained in different layers such as Th lymphocytes subgroups, Notchsignalpathway, PTH and hemorheology. This study aimed to help scholars to understand the mechanism of therapeutic effect of TCM on the treatment of psoriasis vulgaris.

ABSTRACT

Objective To assess the epidemiology and clinical correlates of acute kidney injury(AKI)on patients in department of dermatology. Methods A total of 4710 patients hospitalized in dermatology department with at least two creatinine tests within 7 days were selected as research objects.AKI was defined and staged accord-ing to Kidney Disease Improving Global Outcomes criteria. Results The incidence of AKI was 6.3%. AKI inci-dences of psoriasis with systemic reaction(14.8%),erythroderma(12.8%),drug eruption(12.6%)and systemic lupus erythematosus (12.5%) were significant higher than the total incidence. In multivariate logistic regression model,these 4 skin diseases were independent risk factor of AKI incidence. The OR(95% confidencel interval) was 2.970(2.047~4.310),1.932(1.005~3.717),2.446(1.752~3.415)and 2.254(1.287~3.946). The in-hospital mortality was much higher in patients with AKI than those without(3.1% vs 0.1%,P < 0.001). And the AKI was related to in-hospital death after adjusted by age and comorbidities(Odds ratio 24.630,95%confidencel interval 7.385~82.149 ). Conclusion AKI is common in patients hospitalized in department of dermatology and is associated with patiensts′medical burden ,which shoule be noticed.

ABSTRACT

Objective We aimed to investigate the clinical values of combination of blood creatinine and cystatin C for acute kidney injury(AKI)diagnosi. Methods Total 7 627 patients were studied retrospectively. The AKI was classified by creatinine or cystatin C according to the Kidney Disease:Improving Global Outcomes criteria. Results The maximum levels of cystatin C and creatinine were correlated(Spearman′s rank coefficient 0.699,P < 0.001). The area under a receiver operating characteristic curve of maximum cystatin C value for pre-dicting in-hospital death was 0.761(95% confidence interval 0.693 ~ 0.828). Total 1 004 and 173 patients were classified into AKI by blood creatinine or by cystatin C(13.2% vs.2.3%,P<0.001),respectively.The total inci-dence of AKI was 14.7% diagnosed by the combination of the two markers.In multivariable logistic model,the cre-atinine negative plus cystatin C positive group was associated with a higher in-hospital death compared with the cre-atinine and cystatin C double negative group(OR 15.524,95% confidence interval 5.110 ~ 47.166,P < 0.001). Conclusion Combination of cystatin C increased sensitivity of creatinine for AKI diagnosis and facilitated to iden-tify in-hospital patients with high risk.

ABSTRACT

Nonconvulsive status epilepticus (NCSE)is a peculiar kind of status epilepticus,which is not un-common in children,but it always be misdiagnosed due to its unnoticeable clinical signs.So far,there is no international unifying diagnose standard of NCSE.Therefore,electroencephalography(EEG)monitoring is recommended.Now,the progress in this field of clinical manifestation and EEG features of NCSE was reviewed.

ABSTRACT

OBJECTIVE@#To determine the relationship between the ear protective measures during winter swimming and the prevalence, severity of the incidence of external auditory canal exostoses.@*METHOD@#Three hundred and fifteen people who enjoyed swimming were recruited as research subject (62.2% males and 37.8% females; age distribution: 4.4% were ≤ 40, 40.3% were 41 to 60, and 55.2% were > 60 years). People fill in the questionnaires including personal information, the ear protection measures, the time of winter swimming, the history of ear infections and so on, and questionnaires were correlated with otoscopic findings. We classify external auditory canal exostoses according to the degree of the stenosis of external auditory canal s. Grades of normal,mild, moderate and severe corresponded to 100%, 99% to 66%, 65% to 33%, and less than 33% respectively.@*RESULT@#Of 110 ears with exostoses, 63.6% were mild, 23.6% were moderate, and 12.7% were severe. Among the group of without ear protection during winter swimming, about 33.0% have auditory canal exostoses and 4.6% were severely affected. In comparison, in the group that had ear protection, only 2.8% had external auditory canal exostoses and no one had severely obstructed auditory canal.@*CONCLUSION@#A negative association exists between the ear protection measures during winter swimming and the prevalence and severity of exostoses of the external auditory canal. That means taking ear protective measures when having winter swimming can prevent the onset of the external auditory canal exostoses and reduce its severity.

ABSTRACT

Objective To evaluate the in vitro effect of ferulic acid on the proliferation of,as well as melanin synthesis,tyrosinase activity and expressions of c-kit and ERK proteins in cultured normal human epidermal melanocytes.Methods Cultured normal human epidermal melanocytes were treated with various concentrations of ferulic acid for different durations,and those remaining untreated served as the control.Then,3-(4,5-dimethylthiazol2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium,inner salt (MTS) assay was performed to estimate cell proliferative activity at 24,48 and 72 hours,sodium hydroxide solubilization method to quantify melanin content in melanocytes at 72 hours,dopa oxidation assay to evaluate tyrosinase activity at 72 hours,Western blot to measure the expressions of c-kit and ERK1/2 proteins at 72 hours.Results Cellular proliferative activity was significantly inhibited in melanocytes treated with ferulic acid of 0.01,0.1 and 1 mg/ml for 24,48 and 72 hours compared with untreated melanocytes (all P < 0.05),and the 72-hour treatment with ferulic acid of 1 mg/ml showed the strongest inhibitory effect.Ferulic acid at 0.01,0.1 and 1 mg/ml all markedly suppressed melanin synthesis and tyrosinase activity,decreased the expressions of c-kit and ERK1/2 proteins in melanocytes,with significant differences in these parameters between ferulic acid-treated and untreated melanocytes (all P < 0.05).Conclusions Ferulic acid could downregulate the proliferation of,as well as melanin synthesis,tyrosinase activity,and expressions of c-kit and ERK proteins in cultured human epidermal melanocytes.
