ABSTRACT
Objective:To evaluate the real-world short-term effectiveness of ixekizumab in the treatment of psoriasis, and to investigate factors influencing the effectiveness.Methods:Baseline data and short-term effectiveness evaluation results were retrospectively collected from patients with psoriasis, who received ixekizumab treatment in Department of Dermatology, Xiangya Hospital from November 2019 to September 2021. A descriptive analysis was performed on the baseline characteristics of patients, continuous data were described as median (lower quartile, upper quartile), and categorical data were described as percentages. Comparisons of disease severity scores before and after the treatment with ixekizumab were performed using Wilcoxon signed-rank test or paired McNemar test. Multivariable logistic regression analysis was conducted to explore factors influencing the effectiveness of 4-week ixekizumab treatment.Results:A total of 118 patients with psoriasis were included, including 94 males and 24 females, and their age [ M ( Q1, Q3) ] was 43.4 (32.5, 53.0) years; plaque psoriasis (99 cases, 83.9%) and severe psoriasis (72 cases, 68.6%) predominated among the 118 patients, and skin lesions were mainly located on the scalp (59/116, 50.9%). Among the 49 patients who had received 2-week ixekizumab treatment, 27 (55.1%) achieved a 50% improvement in the psoriasis area and severity index (PASI) score (PASI50) ; after 4-week treatment, 44 (89.8%), 30 (61.2%), 13 (26.5%) and 10 (20.4%) patients achieved PASI50/75/90/100 respectively, and their PASI scores (2.1 [1.1, 7.1]), involved body surface area (3.9% [0.5%, 14.5%]), dermatology life quality index scores (1.0 [0.0, 2.0]) and physician global assessment (PGA) scores (1.0 [1.0, 3.0]) were significantly lower than the corresponding scores at baseline (12.4 [8.8, 23.2], 22.0% [11.3%, 43.4%], 6.0 [3.0, 11.0], 4.0 [3.0, 5.0], respectively; all P < 0.001]. Multivariable logistic regression analysis showed that the baseline body mass index was significantly associated with the PASI75 response rate ( OR = 0.814, 95% CI: 0.659 - 0.958, P = 0.029) and the proportion of patients with PGA0/1 ( OR = 0.743, 95% CI: 0.562 - 0.917, P = 0.017) after 4-week ixekizumab treatment, and the baseline BSA score was significantly associated with the proportion of patients with PGA0/1 after 4-week ixekizumab treatment ( OR = 0.924, 95% CI: 0.870 - 0.968, P = 0.003) . Conclusion:The 4-week ixekizumab treatment significantly decreased the severity of psoriasis, and may be more effective in patients with lower disease severity and lower body mass index at baseline.

Background/Aims@#Non-alcoholic fatty liver disease (NAFLD) is closely associated with metabolic dysfunction. Among the multiple factors, genetic variation acts as important modifiers. Klotho, an enzyme encoded by the klotho (KL) gene in human, has been implicated in the pathogenesis of metabolic dysfunctions. However, the impact of variants in KL on NAFLD risk remains poorly understood. The aim of this study was to investigate the impact of KL rs495392 C>A polymorphism on the histological severity of NAFLD. @*Methods@#We evaluated the impact of the KL rs495392 polymorphism on liver histology in 531 Chinese with NAFLD and replicated that in the population-based Rotterdam Study cohort. The interactions between the rs495392, vitamin D, and patatin-like phospholipase domain containing 3 (PNPLA3) rs738409 polymorphism were also analyzed. @*Results@#Carriage of the rs495392 A allele had a protective effect on steatosis severity (odds ratio [OR], 0.61; 95% confidence interval [CI], 0.42–0.89; P=0.010) in Chinese patients. After adjustment for potential confounders, the A allele remained significant with a protective effect (OR, 0.66; 95% CI, 0.45–0.98; P=0.040). The effect on hepatic steatosis was confirmed in the Rotterdam Study cohort. Additional analysis showed the association between serum vitamin D levels and NAFLD specifically in rs495392 A allele carriers, but not in non-carriers. Moreover, we found that the rs495392 A allele attenuated the detrimental impact of PNPLA3 rs738409 G allele on the risk of severe hepatic steatosis. @*Conclusions@#The KL rs495392 polymorphism has a protective effect against hepatic steatosis in patients with NAFLD.
ABSTRACT
Objective:To analyze the epidemiological characteristics of 8 clusters of coronavirus disease 2019 （COVID-19） in Chenzhou City， and provide scientific basis for epidemic prevention and control. Methods:Descriptive epidemiological analysis was conducted for 8 COVID-19 clusters， comparing and analyzing the differences of infection rates among close contacts within and outside the family， and emphatically describing two typical cases. Results:8 COVID-19 clusters were reported in Chenzhou with a total of 31 cases from January to February， 2020. The main source of infection of the family index cases was Hubei Province. Cough symptoms were observed in 67.74% of the cases， followed by fever （54.84%）. The infection rate of close contacts within the family （55.00%） was higher than that outside the family （2.56%）， and the difference was statistically significant （χ2=28.177， P<0.001）. The infection rate of spouse of the family index cases was 85.71%， higher than that of parents （77.78%）， other family members （44.44%） and children （40.00%）， and the difference was not statistically significant （χ2=6.004， P=0.120）. Two typical cases suggested that both COVID-19 pre-symptomatic and asymptomatic patients have the potential to excrete the virus from the body and become sources of infection. Conclusion:Effective family prevention and control measures and early sampling and screening of people in key epidemic areas are conducive to early detection， early isolation and early treatment of infected people， so as to avoid the occurrence and spread of family clusters.
ABSTRACT
Objective To explore the transmission chain of COVID-19 by serum antibody detection, and to provide scientific evidence for the prevention and control of the epidemic. Methods Field epidemiological investigation was used to determine the COVID-19 cases and their close contacts. The 2019-nCoV nucleic acid in throat swabs and anal swabs were examined by RT-PCR. Serum specimens were collected for anti-2019-nCoV IgM antibody detection and combined IgM/IgG detection. Results Case A had no confirmed exposure to COVID-19. However, case C and D had dinner and lived together with case A; they reported contact history and dinner history with other confirmed COVID-19 cases(H, L). Case A tested positive for 2019-nCoV nucleic acid, whereas case C and D were negative. Moreover, case A and C were IgM antibody positive, while case D was negative. Case A, C and D were all positive for combined IgM/IgG. In addition, case D had clinical symptom, while case C did not. Conclusion Serum antibody detection can be used as an effective supplement to the inference of transmission chain of COVID-19, which may facilitate determining the source of infection and improving the evidence.

ABSTRACT
OBJECTIVES@#Psoriasis is a chronic inflammatory skin disease that affects adults and children. The most common subtype is psoriasis vulgaris. This article analyzes the characteristics and clinical features of children with psoriasis vulgaris to strengthen the understanding, treatment, and management for children with psoriasis.@*METHODS@#A total of 208 children with psoriasis vulgaris, who were first admitted to the Department of Dermatology, Xiangya Hospital, Central South University from October 2012 to December 2018, were retrospectively analyzed. Their clinical characteristics, results of laboratory examination, treatment options and efficacy were summarized.@*RESULTS@#The age of the 208 children with psoriasis vulgaris was (11.19±3.97) years old, the peak incidence was 12 years old, the disease duration was (27.46±31.30) months, and the male-female ratio was 1∶0.96. The most common site of the first attack was the scalp (37.98%), followed by the trunk (26.44%) and the limbs (22.12%). The causes leading to exacerbation were more common in infections and diets. There were 33 patients (15.87%) with a family history of psoriasis, showing the higher score of Psoriasis Area and Severity Index (PASI) and the higher Dermatological Quality of Life Index (DLQI) (both <0.05). In all patients, 29 cases (13.94%) were overweight, 19 cases (9.14%) were obese, and the rate of overweight and obesity in children with psoriasis vulgaris was higher than that of normal children in China. In the laboratory test, the serum levels of 25-hydroxyvitamin D (25-OH-VD) were decreased in most patients (47.5%), and the serum 25-OH-VD levels were found to be moderately negatively correlated with PASI score (<0.05). The score of DLQI in the patient was 5.56±3.57, the score of PASI was 7.25±6.83, and they were positively correlated (=0.409, <0.001). In most patients (72.11%), the severity of the disease was mild to moderate. Their treatment was often dominated by topical drugs and Chinese patent medicine (65.67%). Retinoids showed a good effect on children. Cyclosporine and methotrexate were effective in more severe cases.@*CONCLUSIONS@#Children with psoriasis vulgaris are mainly caused by infection and diet. Patients with family history have more serious illness, lower quality of life, and are more likely to have metabolic abnormalities such as overweight and obesity. The serum 25-OH-VD levels in children with psoriasis vulgaris are negatively correlated with the score of PASI.

BACKGROUND@#The association between free triiodothyronine (FT3) and long-term prognosis in dilated cardiomyopathy (DCM) patients has not been evaluated. The purpose of this study was to determine whether the level of FT3 could provide prognostic value in patients with DCM.@*METHODS@#Data of consecutive patients diagnosed with DCM were collected from October 2009 to December 2014. FT3 was measured by fluoroimmunoassay. Other biochemical markers, such as free thyroxin (FT4), thyroid-stimulating hormone, red blood cell, hemoglobin, blood urea nitrogen, and serum creatinine, were tested at the same time. Follow-up was performed every 3 months. The primary endpoint was all-cause mortality. Pearson analysis was used to evaluate the correlation of FT3 and other lab metrics with DCM patients' prognosis. The association of long-term mortality in DCM and FT3 was compared using Cox hazards model.@*RESULTS@#Data of 176 patients diagnosed with DCM were collected. Of them, 24 patients missed FT3 values and six patients were lost to follow-up. Altogether, data of 146 patients were analyzed. During the median follow-up time of 79.9 (53.5-159.6) months, nine patients lost, 61 patients died (non-survival group), and 85 patients survived (survival group). FT3 was significantly lower in non-survival group than that in survival group (3.65 ± 0.83 pmol/L vs. 4.36 ± 1.91 pmol/L; P = 0.003). FT3 also showed a significantly positive correlation with red blood cell and hemoglobin, negatively correlated with age, blood urea nitrogen and serum creatinine (P < 0.05), respectively. Patients in the group of lower FT3 levels (FT3 ≤3.49 pmol/L) suffered from a higher risk of all-cause mortality (P for log-rank = 0.001). In multivariate Cox regression analysis, FT3 level was significantly associated with all-cause mortality (hazard ratio: 0.70, 95% confidence interval 0.52-0.95, P for trend = 0.021).@*CONCLUSION@#Low levels of FT3 were associated with increased all-cause mortality in patients with DCM.
ABSTRACT
Objective To determine the diagnosis value of urinary albumin(mAlb)/creatinine(Ucre) ratio in random urine from patients with early diabetic nephropathy.Methods From March 2015 to December 2016,98 case with simple diabetes and early diabetic nephropathy in Ankang Hospital of Traditional Chinese Medicine were selected,including 47 cases with simple diabetes and 51 cases with early diabetic nephropathy.And 60 healthy people were selected as control group.The mAlb and mAlb/Ucre ratios in morning urine,postprandial urine and random urine were detected for three times in three days,and the resluts were calculated and analyzed.Results In early diabetic nephropathy group,the mAlb concentration varied during different time periods,mAlb in morning urine [(60.5 ± 27.1)mg/L] and postprandial urine [(60.7 ± 26.7)mg/L] were significantly increased compared with that in random urine [(40.9 ± 25.1) mg/L] (F =9.551,P =0.000).The MAlb/Ucre ratios were stable in morning urine,postprandial urine and random urine of each period (P ＞ 0.05).The positive rate of mAlb/Ucre ratio was sharply higher than mAlb alone in random urine (90.2％ vs.62.7％).No statistically significant difference showed in positive rates of mAlb/Ucre ratio in subjects from different groups(the positive rate of morning urine specimen was 92.2％;postprandial urine 88.2％;random urine 90.2％,P ＞ 0.05).Conclusion Positive rate of mAlb/Ucre ratio changed slightly during different test periods,and is superior to mAlb alone in clinic application.Additionally,the positive rate of mAlb/Ucre ratio in random urine could serve as an indicator in early screening of early diabetic nephropathy.
ABSTRACT
Objective To study the epidemiological characteristics of imported malaria in Chenzhou City, Hunan Province, so as to provide the reference for consolidating the malaria elimination and formulating the prevention and control strategies of imported malaria. Methods The epidemiological characteristics of imported malaria were statistically analyzed in Chenzhou City from 2010 to 2017. Results Totally 46 malaria cases, which were all imported, were reported in Chenzhou City from 2010 to 2017, with an average annual incidence of 0.12/105. The reported malaria cases were mainly falciparum malaria, accounting for 60.87% of the total number of cases. There was no obvious seasonal distribution of malaria cases, but the top of reported cases were in June. Totally 73.91% of malaria cases were concentrated in Beihu District, Suxian District, Guiyang County and Zixing City. These cases were mainly the young and middle-aged and 69.57% of the cases were from 36 to 60 years old. There was a statistically significant difference in the distribution of malaria patients among the age groups (χ2 = 47.80, P < 0.01). The median time from onset to diagnosis was 6 days, and the case confirmed institutions were dominated by municipal and above medical institutions, accounting for 52.17% of the total number of cases. There was a statistically significant difference in the proportion of confirmed cases among medical and health institutions at all levels ( χ2 = 41.96, P < 0.01). Conclusions The importation of malaria in Chenzhou City is still severe. The awareness of malaria diagnosis and treatment in primary medical institutions, malaria patients' serum tests, and the health education of malaria control and prevention knowledge should be strengthened to consolidate the malaria elimination results.

ABSTRACT
Objective:To investigate the correlation of the concentrations of valproic acid (VPA) and 2-propyl-4-pentenoic acid (4-ene-VPA) with their adverse reactions,and to guide the clinical safety and rational use of VPA.Methods:We collected 254 epilepsy outpatients who took long-term use of sodium valproate oral solution single or combined with other antiepileptic drugs from Xiangya Hospital.The plasma concentrations of VPA and 4-ene-VPA in patients were determined by gas chromatography-mass spectrometry (GC-MS).The double variable correlation analysis was performed to analyze the effect of plasma 4-ene-VPA and VPA concentrations on adverse reactions.Results:The correlations between the PLT level and the dosage ofVPA (P＜0.01 and P＜0.05,respectively),and the RBC level and the concentration of VPA (All P＜0.01) were significant negatively.The concentrations of 4-ene-VPA,VPA,ALT,and AST in the polytherapy group were much higher than those in the monotherapy group (All P＜0.05).In the monotherapy group,the ALT and AST levels in patients younger than or equal to 2 years old were significantly higher than those over 2 years old (P＜0.001).In the polytherapy group,the levels of AST,WBC,and PLT in patients younger than or equal to 2 years old were higher than those over 2 years old (P＜0.05).The levels of AST did not show positive correlation with the concentrations of 4-ene-VPA and VPA (r=0.031,r=0.035,all P＞0.05),and the levels of ALT also did not show positive correlation with the concentrations of 4-ene-VPA and VPA (r=-0.064,r=-0.089,all P＞0.05).Conclusion:VPA may affect blood routine indexes.Age and combination therapy with the non-enzyme-induced anti-epileptic drugs are risk factors for VPA-related liver dysfunctions and renal impairment.The determination of VPA and 4-ene VPA is not a suitable tool for early warning of the VPA-induced liver dysfunction.
ABSTRACT
@#Objective To explore the safety and effectiveness of video-assisted thoracoscopic surgery (VATS) pneumonectomy for bronchiectasis. Methods The clinical data of 164 patients undergoing VATS pneumonectomy or open thoracotomy for bronchiectasis in our hospital from March 2002 to July 2012 were retrospectively analyzed. Patients were divided into two groups according to different surgical methods: a thoracotomy group (122 patients, 63 males, 59 females) and a thoracoscopic surgery group (42 patients, 15 males, 27 females). Surgical and follow-up indicators were compared between the two groups. Results There was no difference between the two groups in the blood loss, operation time, perioperative mortality or complication. However patients undergoing VATS had shorter length of postoperative stay than those undergoing thoracotomy (6.9±2.6 d vs. 8.1±3.1 d, P=0.030). In the thoracoscopic surgery group, 3 patients were lost to follow-up and in the thoracotomy group, 5 patients were lost to follow-up. In a median follow-up of 51 months (ranging from 2 to 116 months), 36 patients (92.3%) fully recovered with no sputum or haemoptysis and 3 (7.7%) partially recovered with a reduced sputum or haemoptysis in the thoracoscopic surgery group; 105 (89.7%) fully recovered with no sputum or haemoptysis, 10 (8.5%) partially recovered with a reduced sputum or haemoptysis while 2 (1.7%) without any improvement in the thoracotomy group with no statistical difference (P=0.700). Conclusion VATS pneumonectomy for bronchiectasis is equivalent to thoracotomy in terms of safety and effectiveness, and can be used as an alternative surgical procedure for the treatment of bronchiectasis.
ABSTRACT
To explore the role of methotrexate (MTX) in regulating the number of regulatory T cells (Treg) and the mRNA expression of transcription factor Foxp3. Methods: 1) We analyzed the number of Treg and the mRNA expression of Foxp3 by flow cytometry (FCM) and quantitative real-time PCR (qRT-PCR) respectively in patients with psoriasis vulgaris, patients with psoriasis vulgaris after the 8-week treatment of MTX, and healthy people. 2) BALB/c female mice were smeared with imiquimod (IMQ) cream for 6 days. We recorded the change of the lesion in mice every day. The morphological changes of lesion in mice were evaluated by the psoriasis area and severity index (PASI) and HE staining. 3) The mouse model was randomly divided into a control group and an MTX group. The MTX group was treated with different doses of MTX (38.5 and 77.0 nmol/L) on the third day of this experiment. The morphological changes of lesion in mice were evaluated by PASI and HE staining. We tested the number of Treg and the expression level of Foxp3 mRNA in splenic lymphocytes. Results: 1) The number of Treg and the expression level of Foxp3 mRNA were lower in psoriasis vulgaris patients than those in the healthy control group (P<0.05). After 8-week treatment of MTX, the number of Treg was increased (P<0.05) and Foxp3 mRNA level was up-regulated (P<0.01). 2) Typical psoriasis-like skin lesions, such as red scaly skin plaque were found after topical application of IMQ. Both the number of Treg in the splenic lymphocytes of mice and the Foxp3 mRNA level of Treg were reduced by IMQ (P<0.01 and P<0.05). 3) Different doses of MTX for mice showed the ability to improve skin lesion, increase the number of Treg in the spleen of mice and Foxp3 mRNA level in psoriatic dermatitis of mice (P<0.05). Conclusion: MTX is able to regulate the number of Treg and Foxp3 mRNA expression in psoriasis.

The applied value of serum hepcidin in differential diagnosis of infection fevers versus tumor fevers was explored.A total of 432 fever patients were selected according to the domestic fever of unknown origin (FUO) diagnostic criteria from our hospital between June 2010 and November 2013.Venous blood samples were taken on the day 1,5,10 after admission.The infection group (98 cases) and the tumor group (50 cases) were set up based on the clinical and laboratory findings.ELISA was used to determine the serum hepcidin and IL-6 levels.SPSS 13.0 was used for statistical analysis.Hepcidin showed obvious descending trend on the 10th day in both the bacterial infection group (66 cases) and the virus infection group (32 cases),and the descending trend was similar to that of inflammatory indexes such as procalcitonin (PCT),hypersensitive C-reactive protein (h-CRP),erythrocyte sedimentation rate (ESR),white blood cell (WBC),and ferritin.Serum hepcidin showed no obvious differences in the tumor group on the day 1,5,10 after admission.In the infection groups,serum hepcidin was positively correlated with IL-6 (r=0.687,P=0.000) and CRP (r=0.487,P=0.026),but had a poor correlation with blood sedimentation,ferritin,PCT and WBC (P＞0.05).Monitoring dynamic changes of hepcidin and related inflammatory factors in patients with fever is expected to be used for clinical identification of infection fever and tumor fever.
ABSTRACT
OBJECTIVE@#To realize the risk factors, clinical features, and treatments of Staphylococcal scalded skin syndrome (SSSS). @*METHODS@#The clinical features, laboratory findings, and treatment were retrospectively analyzed in 290 patients from Hunan Children's Hospital. @*RESULTS@#Of the 290 patients, less than 3 years old children were 76.6%. One hundred and nine patients had induced factors, and 177 patients had elevated white blood cell count. There were 168 patients with SSSS accompanied with fever, 34 patients accompanied with diarrhea, and 58 patients associated with septicemia. Eighty-five patients performed the bacterial cultures of the skin secretions, 21 did the throat swab, and 13 did both of the skin secretions and throat swab. Bacterial culture results showed that 119 samples were positive for Staphylococci. All patients were cured after antimicrobial therapy. The skin lesions were improved in 3.26 d. The mean hospital stay was 6.55 d. Recovery time of the body temperature was 3.48 d in average. @*CONCLUSION@#SSSS predominates in infants and children under 3 years old, and has tendency to combine with multi-organ symptoms. The early diagnosis and active antimicrobial treatment are the keys of successful treatments.
