RESUMO
To assess the reliability, validity and responsiveness of the Chinese version of the atopic dermatitis control tool (ADCT). After this study obtained authorization for the Chinese version of the ADCT scale. 114 patients with atopic dermatitis were enrolled from the Department of Dermatology, Peking University First Hospital using convenience sampling from October 2022. Patients were surveyed using the General Information Questionnaire, Chinese version of ADCT, patient-oriented eczema measure (POEM),peak pruritus numerical rating scale (PP-NRS),dermatology life quality index (DLQI) and the global patient self-assessment for disease severity. Mann-Whitney rank sum test and Spearman correlation analysis were used for item analysis; content validity was assessed using content validity index (CVI); exploratory factor analysis was used to assess structural validity; Cronbach' alpha coefficient was used to assess internal consistency; Spearman correlation analysis was used to assess the correlation of ADCT with other scales to assess external responsiveness. The results showed that all items were retained by item analysis. I-CVI was 0.9-1, and S-CVI/Average was 0.983; the scale extracted one common factor by factor analysis, the cumulative variance explanation rate was 77.927%; the Cronbach' alpha coefficient of the scale was 0.937; the correlation coefficients of the Chinese version of ADCT with POEM, PP-NRS, and DLQI were 0.805, 0.861, and 0.709 respectively. In conclusion, the Chinese version of the ADCT has adequate reliability, validity and responsiveness, and is suitable for measuring disease control in Chinese patients with atopic dermatitis.

OBJECTIVES@#To study the association between early-life factors (including birth weight, method of birth, gestational age, and history of gestational metabolic disorders) and pubertal timing in girls.@*METHODS@#The stratified cluster sampling method was used to select the girls in grades 2-3 and 7-8 from three primary schools and three middle schools in Guangzhou, China from March to December, 2019, and breast development was examined for all girls. A questionnaire survey was performed to collect the information on early-life factors. The multivariate logistic regression model was used to evaluate the association of gestational metabolic disorders, birth weight, method of birth, and gestational age with pubertal timing in girls. The Bootstrap method was used to assess the mediation effect of body mass index (BMI) (Z score) between high birth weight (≥4 000 g) and pubertal timing.@*RESULTS@#A total of 1 665 girls were enrolled, among whom 280 (16.82%) were judged to have early pubertal timing. The multivariate logistic regression analysis showed that high birth weight was associated with the increased risk of early pubertal timing (OR=2.12, 95%CI: 1.19-3.66, P=0.008). Nevertheless, no significant association was observed between other early-life factors and pubertal timing (P>0.05). The OR for the mediation effect of BMI (Z score) between high birth weight and early pubertal timing was 1.25 (95%CI: 1.09-1.47), accounting for 29.33% of the total effect of high birth weight on early pubertal timing.@*CONCLUSIONS@#High birth weight is associated with the increased risk of early pubertal timing in girls, and overweight/obesity may play a partial mediating role in the association between high birth weight and early pubertal timing in girls.

Objective:To investigate the application value of intravoxel incoherent motion (IVIM) imaging in preoperative evaluating perineural invasion (PNI) of esophageal squamous cell carcinoma (ESCC).Methods:The prospective study was conducted. The clinicopathological data of 63 ESCC patients who underwent IVIM imaging before surgery in the Affiliated Cancer Hospital of Zhengzhou University & Henan Cancer Hospital from January 2016 to April 2019 were selected. Patients underwent routine magnetic resonance imaging scan and IVIM sequence examination. The apparent diffusion coefficient (ADC), true diffusion coefficient (D), pseudodiffusion coefficient (D*) and pseudodiffusion fraction (f) values were measured. Observation indicators: (1) situations of enrolled patients; (2) IVIM examination of PNI of ESCC and its diagnostic efficiency. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was analyzed using the independent sample t test. Measurement data with skewed distribution were represented as M( Q1, Q3) or M(range), and comparison between groups was analyzed using the Wilcoxon rank sum test. Count data were described as absolute numbers, and comparison between groups was analyzed using the chi-square test. The interclass correlation coefficient (ICC) was used to evaluate cosistency of results. The receiver operating characrteristic curve was used to evaluate diagnostic efficiency. Results:(1) Situations of enrolled patients. A total of 63 patients were selected for eligibility. There were 41 males and 22 females, aged 60(range, 43?74)years. Of the 63 ESCC patients, 17 cases had PNI and 46 cases had no PNI. Cases with well differentiated tumor, moderate differentiated tumor or low differentiated tumor, cases in stage T1, T2, T3, T4 of infiltra-tion depth, cases with or without lymph node metastasis were 0, 6, 11, 0, 3, 13, 1, 15, 2 in patients with PNI, versus 6, 24, 16, 1, 22, 23, 0, 12, 34 in patients without PNI, showing significant differences between them ( Z=?2.32, ?2.49, χ2=19.58, P<0.05). (2) IVIM examination of PNI of ESCC and its diagnostic efficiency. The ADC, D, D*, f values were (2.21±0.33)×10 ?3 mm 2/s, (1.46±0.31)×10 ?3 mm 2/s, 32.50 (15.55,46.75)×10 ?3 mm 2/s, (0.34±0.09)×10 ?3 mm 2/s in patients with PNI, versus (2.45±0.45)×10 ?3 mm 2/s, (1.72±0.38)×10 ?3 mm 2/s, 34.85(23.43,51.20)×10 ?3 mm 2/s, (0.42±0.13)×10 ?3 mm 2/s in patients without PNI, showing significant differences in the ADC, D and f values between them ( t=?2.03, ?2.52, ?2.34, P<0.05) and no significant difference in the D* value between them ( Z=?0.84, P>0.05). The cosistency of ADC, D, D* and f values in the 63 ESCC patients measured by 2 radiologists was good, with the ICC as 0.96, 0.92, 0.89 and 0.95. The receiver operating characrteristic curve demons-trated the best cut-off value of ADC, D and f values were 2.50×10 ?3 mm 2/s, 1.68×10 ?3 mm 2/s and 0.41, with the areas under the curve as 0.67 (95% confidence interval as 0.54?0.79), 0.70 (95% confidence interval as 0.58?0.81) and 0.69 (95% confidence interval as 0.57?0.80), respectively. The combina-tion of D and f value for diagnosing PNI of ESCC had the area under the curve as 0.74 (95% confidence interval as 0.62?0.84), with the cut-off value as 0.20, sensitivity and specificity as 94.1% and 56.5%. Conclusions:IVIM parameters D and f values can evaluate and predict the PNI of ESCC preopera-tively. The combination of D and f values can further improve the diagnostic efficiency.
RESUMO
β-thalassemia is a single-gene genetic disease caused by β globin gene mutations leading to the fact that red blood cells are unable to form normal adult hemoglobin, and then patients develop hemolytic anemia. Current treatment regimens mainly include allogenetic hematologic stem cell transplantation, symptomatic regular blood transfusions and the use of iron removers to reduce iron load. Some severe patients have quite poor prognoses and deadly consequences if not treated timely. Genetically modified autohematopoietic stem cells can provide a new treatment option for patients with β thalassemia, which may achieve a long-term and stable increase in hemoglobin level through a single dose, making one-time cure β-thalassemia possible. This paper reviews the key elements of clinical trial design for β-thalassemia gene therapy from the aspects of efficacy evaluation endpoints, clinical trial design, enrollment population, and subject monitoring in order to provide a reference for pharma-therapeutic research and development enterprises.

Objective:To investigate the standardized training needs of new nurses in Yunnan province and provide scientific basis for the formulation of standardized training programs for new nurses.Methods:From December 2019 to September 2020, nurses from all 5 provincial tertiary Class A hospitals in Yunnan Province were selected as the research objects. A questionnaire survey was conducted among 712 nurses selected by the convenience sampling method, among which 456 were new nurses and 256 were senior nurses. The questionnaire was designed by the research team based on the Training Outline for Newly Recruited Nurses, which mainly included three dimensions of knowledge, skills and attitude.Results:The total score of new nurses and senior nurses on standardized training requirements for new nurses were (575.32 ± 85.76) points and (583.16 ± 86.32) points, which were above the average level. There was no statistically significant difference between the scores of training theme needs of new nurses and those of senior nurses ( t value was -1.168, P>0.05). Conclusions:The total score of standardized training needs of new nurses is above the average level, and the demand for knowledge dimension in standardized training of new nurses is the strongest. It is suggested to develop a systematic and scientific standardized training plan for new nurses according to the training needs and training methods.
RESUMO
Objective:To analyze the current status of body composition and development patterns of children and adolescents aged 6-17 years in Guangzhou.Methods:This was a cross-sectional study involving 8 169 school students from 3 elementary schools and 3 middle schools in Guangzhou from March to December 2019.The fat-free mass (FFM) and fat mass (FM) were measured by the bioelectrical impedance analysis.The fat-free mass index (FFMI) and fat mass index (FMI) were calculated via the height standardization. T test was used to compare quantitative variables between groups.The growth pattern of body composition was described using the Hattori chart. Results:A total of 4 431 boys (54.24%) and 3 738 girls (45.76%) were involved in this study.FFM and FM both increased with age between boys and girls.Except for boys aged 11 years, FFM in boys were significantly higher than that in girls with the same age (all P<0.05). In the age of 7-10 years, FM in boys were significantly higher than that in girls with the same age, while it was significantly higher in girls aged 12 years and older than that of boys at the same age (all P<0.05). The Hattori chart showed that the difference in body composition between genders occurred after 11 years old.In contrast to girls, increases in the weight and body mass index (BMI) in boys were mainly attributed to the FFM development. Conclusions:The development of FFM and FM in children and adolescents varies with age, accompanied with the gender-specific features.FFM in boys is higher than that of girls at the same age.The weight gain in boys is mainly attributed to the development of fat-free tissues, and thus the utility of BMI may lead to the overestimation of obesity.
RESUMO
Objective: To investigate the prevalence of dyslipidemia, and to explore the association between extracurricular physical activity and dyslipidemia among primary, middle and high school students in Guangzhou. Methods: This cross-sectional study selected primary and middle school students in Guangzhou by the stratified cluster sampling method from March to December 2019. Physical examination and blood lipid test were performed. Information about students' basic characteristics and extracurricular physical activity was collected by questionnaire. Multivariate logistic regression analysis was used to determine the association between extracurricular physical activity and dyslipidemia in this cohort. Results: A total of 7 797 participants (mean aged (12.2±2.9) years) were included (4 194 (53.79%) boys and 3 603 (46.21%) girls]. The detection rates of high total cholesterol, high triglycerides, low high-density lipoprotein cholesterol, high low-density lipoprotein cholesterol and dyslipidemia were 12.49% (974/7 797), 6.44% (502/7 797), 6.62% (516/7 797), 11.31% (882/7 797) and 23.83% (1 858/7 797), respectively. Dyslipidemia rate was lower in the junior school students (21.39% (675/3 156)) than in primary school students (25.96% (896/3 451)) and high-school students (24.12% (287/1 190)) (P<0.001). The dyslipidemia rates of boys and girls were similar (23.15% (971/4 194) vs. 24.62% (887/3 603), P>0.05). Dyslipidemia rate was lower in students with extracurricular physical activity than in students without extracurricular physical activity (22.50% (923/4 102) vs. 25.30% (935/3 695), P<0.05). Multivariate logistic regression analysis showed that extracurricular physical activity was associated with lower risk of dyslipidemia (OR=0.88, 95%CI=0.79-0.99, P=0.033). Among all types of extracurricular physical activities, participating in extracurricular large ball game was associated with 28% lower risk among junior school students (OR=0.72, 95%CI=0.57-0.91, P=0.006). Conclusion: The prevalence of dyslipidemia is high among primary, middle and high school students in Guangzhou. Extracurricular physical activity is associated with reduced risk of dyslipidemia in this cohort.
RESUMO
Objective:To explore the value of intravoxel incoherent motion (IVIM) DWI in preoperative prediction of angiolymphatic invasion in esophageal squamous cell carcinoma (ESCC).Methods:From April 2016 to April 2019, 63 ESCC patients who planned to undergo resection of esophageal cancer were prospectively collected at Henan Cancer Hospital.According to the postoperative pathological results, 63 patients were divided into angiolymphatic invasion group (30 cases) and no angiolymphatic invasion group (33 cases). All patients underwent IVIM sequence and routine MRI examination before operation. The ADC, true diffusion coefficient (D), pseudodiffusion coefficient (D *) and pseudodiffusion fraction (f) were measured. The differences of parameter values between ESCC with and without angiolymphatic invasion were analyzed using Student′s t test or Wilcoxon rank sum test.The logistic regression was used to analyze the significance of various parameters. For the parameters with statistical significance, the ROC curves were performed to evaluatethe diagnostic performance of parameters for identifying angiolymphatic invasion.The Z test was used to compare the area under the ROC curves(AUC) of parameters. Results:The difference of ADC, D and f values between angiolymphatic invasion group and no angiolymphatic invasion group were statistically signi?cant ( t=4.476, 5.033 and 5.712 respectively, all P<0.001). The D * values showed no statistically signi?cant di?erence ( Z=0.184, P=0.854). The logistic regression analysis showed that D (OR=9.042) and f (OR=26.221) were in correlation with angiolymphatic invasion. The ROC analyses demonstrated that the AUCs of ADC, D and f values in predicting angiolymphatic invasion of ESCC were 0.787, 0.822 and 0.853, respectively. D combined with f had highest AUC (0.917) in predicting the angiolymphatic invasion of ESCC, sensitivity and specificity were 93.3% and 75.8%. D combined with f showed better diagnostic performance than the D and the f value, and the difference were statistically significant ( Z=2.403, 2.289, P=0.016, 0.022). Conclusions:IVIM can be used as an effective functional imaging modality for preoperative evaluation and prediction of the angiolymphatic invasion of ESCC. D value combined with f value can further improve prediction performance of angiolymphatic invasion.

OBJECTIVE：To establish c harge-by-dose model for pediatric drugs in our hospital ，so as to provide reference for reducing patients ’expenditure，saving medical insurance funds and reducing drug proportion. METHODS ：Since June 2019，a total of 12 kinds of drugs with heavy usage ，high price and large savings in our hospital were selected to establish pediatric charge-by-dose list. The drugs included in the list were split into 1/2 or 1/5 small-sized drug for charge-by-dose model. The process，quality control standards and surplus （loss）drug record of charge-by-dose model were formulated to coordinate the use of pediatric drugs between pharmacies and pediatric departments. The quantity and amount of drugs which were split ，and the drug proportion in pediatric departments were compared between charge-by-dose model and charge-by-unit model （theoretical value of dosage conversion in the same period ）during Jun.-Dec. 2019. RESULTS ：From Jun. to Dec. 2019，the quantities of split drugs each month with charge-by-dose model and charge-by-unit model were （3 346.43±734.73）and（6 821.71±1 468.81）；the amounts of split drugs each month with two models were （53 576.03±10 958.78）yuan and （112 642.75±21 308.77）yuan， respectively，with statistical significance （P＜0.05）. The drug proportion in four pediatric internal medicines departments and one neonatal medicine department had decreased to varying degrees. CONCLUSIONS ：Pediatric drug charge by dose can reduce the use and amount of drugs ，save medical insurance expenditures ，decrease the drug proportion of department.
RESUMO
Objective To investigate the correlation between quantitative parameters of dynamic contrast?enhanced MRI (DCE?MRI) after neoadjuvant chemotherapy and pathological grades in esophageal squamous cell carcinoma. Methods Fifty?six patients with esophageal squamous cell carcinoma who were confirmed by esophagoscope and received neoadjuvant chemotherapy before operation between September 2015 and December 2017 in the Affiliated Cancer Hospital of Zhengzhou University were prospectively analyzed, and MRI examination was performed within one week before operation. All patients underwent routine chest MRI and DCE?MRI scanning, and quantitative parameters of DCE?MRI, including volume transfer constant (Ktrans),exchange rate constant (Kep) and extravascular extracellular volume fraction (Ve) were measured. Pathological grading was assessed as highly differentiated, moderately differentiated, poorly differentiated,and undifferentiated. Intraclass correlation coefficient (ICC) was calculated from the results of two radiologists. Kruskal?Wallis H test was used to compare the differences of quantitative parameters between different pathological grade groups of DCE?MRI,and Mann?Whitney U test was utilized to compare the intraclass differences among pathological grades. Spearman rank correlation analysis was performed for evaluating the correlation between DCE?MRI parameters and pathological grade of esophageal squamous cell carcinoma. The receiver operating characteristic (ROC) curves were used to evaluate the diagnosis accuracy of different DCE?MRI parameters in pathological grade of esophageal squamous cell carcinoma after neoadjuvant chemotherapy. Results The 56 patients were divided into four groups according to pathological findings: well differentiated group (n=8), moderately differentiated group (n=39), poorly differentiated group (n=9) and undifferentiated group (n=0). The differences of Ktransmean,Ktrans75%,Kepmax, Kepmean,Kep75% between different pathological grading groups were statistically significant (all P<0.05),and these parameters showed positive correlation significantly with pathological grading (r values were 0.778, 0.632, 0.594, 0.725, 0.489 respectively, all P<0.05). The ROC curve area of Ktransmean, Ktrans75% in the diagnosis of pathological grade for esophageal squamous cell carcinoma was 0.750,0.856,respectively. The diagnostic efficiency of Ktrans75% was the best with the diagnostic threshold of 0.693/min,sensitivity of 87.5%, specificity of 78.5%, respectively. Conclusion The quantitative parameters of DCE?MRI after neoadjuvant chemotherapy in esophageal squamous cell carcinoma have the potential value for predicting pathological grade.
RESUMO
Objective To evaluate the operative outcomes of a triple procedure including simultaneous penetration keratoplasty (PKP),extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation,and to investigate the relationship between postoperative corneal refractive power and preoperative lens diopter.Methods This retrospective analysis study involved 15 patients who had undergone a triple procedure surgery in Beijing You'an hospital from April to October 2016.Outcomes including the best corrected visual acuity (BCVA),intraocular pressure (IOP),corneal refractive power,axial length,postoperative complications,corneal endothelial cell counts and the survival of corneal graft were determined one year after surgery.Results All corneal grafts were transparent and corneal endothelium were (1974.20 ±472.82) cell · mm-2.The mean postoperative LogMAR visual acuity (0.80 ±0.27) had a significant improvement compared with the mean preoperative LogMAR visual acuity (2.63 ±0.62) (t =13.042,P ＜0.001).There were no statistically significant differences in preoperative IOP (15.27 ± 2.37) mmHg (1 kPa =7.5 mmHg) and postoperative data (14.53 ± 3.04) mmHg (t =0.685,P =0.505),preoperative axial length (23.69 ±2.01) mm and postoperative data (23.62 ±2.12)mm (t =-0.138,P=0.893)and preoperative keratometry (45.01 ± 1.66) D of the control eye and postoperative data (42.56 ± 5.48) D (t =1.202,P =0.260).The postoperative spherical equivalent refractive was (0.40 ±4.65) D,and the target refraction was (0.58 ±0.25)D.Conclusion The triple procedures are safe and effective for the treatment of patients with coexisting corneal pathologies and cataracts.Selection of emmetropia lens diopter may result in the satisfactory postoperative visual acuity.However,unpredictable postoperative corneal curvature changes will still affect the final refractive state.
RESUMO
Objective To investigate the current status of mouse euthanasia methods in China,and to provide the reference and basis for the administrative authorities of laboratory animal management to master the implementation of"euthanasia"and formulate related policies. Methods Research papers containing the terms of"mouse"and"execution"in Chinese characters during the period from 2015 to 2016 were searched in Wanfang database,and statistical analysis was performed with the articles meeting the searching criteria. Results A total of 890 research articles met the searching criteria,of which 351 articles clearly described the killing method, accounting for only 39.44%. The mouse-killing methods included cervical dislocation, decapitation, exsanguination and sampling after anesthesia, excessive anesthesia,abdominal aorta bleeding and carbon dioxide asphyxiation, among them cervical dislocation accounted for the highest rate,75.78%. Conclusions The current implementation of mouse euthanasia methods in our country has been far from optimistic. The mouse euthanasis methods have often been ignored in scientific articles and the description of the methods is not standardized. In order to promote the effective implementation of the regulations related to mouse euthanasia,it is needed to promote the study of related techniques and to strengthen personnel training.

This article collected and reported the related literature at home and abroad in recent years, found that pharmacological active ingredients of Herba Hedyotis Diffusae show consistency of polysaccharides and flavonoids to varying degrees, and summarized the pharmacological effects and extraction and purification process. The author believed that, the study about Herba Hedyotis Diffusae has made relatively great achievements, but the research mainly focused on polysaccharides or flavonoids, and efficacy of Herba Hedyotis Diffusae was not in enough in-depth exploration. The indicator of extraction and purification process is relatively single. This study estimated the mechanism of Herba Hedyotis Diffusae from the aspects of absorption and metabolism of intestinal flora and relationship between medicine structure and exert efficacy, hoping to optimize the extracting processes by multiple indexes, and provided references for further exploitation and utilization of Herba Hedyotis Diffusae.
RESUMO
Objective To study and compare the metabolism of Hedyotis diffusa flavonoid extract in intestinal flora from human, normal rats and pseudo germ-free rats in vitro. Methods Intestinal flora of human, normal rats and pseudo germ-free rats were incubated with Hedyotis diffusa extract, rutosid, isoquercitrin and quercitrin under anaerobic conditions at 37℃.High-performance liquid chromatography with diode-array detection ( HPLC-DAD ) was used for the analysis of components and metabolic products.The trends of metabolic transformation of the various components were analyzed according to the changes in chromatographic peak areas at different incubation time points. Results The components of Hedyotis diffusa extract and its monomer were quickly metabolized by human and normal rat intestinal flora and the main metabolite was quercetin.However, they were hardly metabolized by intestinal flora from pseudo germ-free rats. The metabolism effect of intestinal flora was weaker on components than on the corresponding monomers. Conclusion By comparing flavonoids metabolism in intestinal flora from human, normal rats and pseudo germ-free rats, the important role of intestinal microflora in the metabolism of flavonoids is further confirmed.

Conclusion:Based on a mobile phone short message technology platform, indi-vidualized clinical pharmaceutical guidance can significantly improve the medication compliance in diabetic patients.
RESUMO
<p><b>OBJECTIVE</b>To study expression of regucalcin (RGN) and prohibitin (PHB) genes in cirrhotic rat liver and to investigate the related effects of compound glutathione inosine injection (CGII) intervention.</p><p><b>METHODS</b>Forty male Wistar rats were randomly divided into a control group (n=12) and a model group (n=28).The model was established by injecting sterile porcine serum (0.5 mL) into the rat abdominal cavity, twice weekly for 8 consecutive weeks; the control group rats were treated with physiological saline injection (0.5 mL) into the abdominal cavity with the same frequency and time span. During the modeling period, four rats from the model group were randomly selected at different time points to examine changes in liver pathology. Upon pathology confirmation of liver cirrhosis, the porcine serum injection was terminated. The remaining 24 rats in the model group were randomly divided into a fibrosis group and a CGII treatment group.The CGII group received CGII (intramuscular injection of 0.018 mL 100g-1 body weight) once a day for 6 continuous weeks; the fibrosis rats were treated with the same dosage of physiological saline with the same frequency and time span.Liver tissue morphology was examined by both hematoxylin-eosin and Masson's staining. RGN and PHB expression at the mRNA and protein levels in liver tissues were detected by real time RT-PCR and immunohistochemical staining, respectively.</p><p><b>RESULTS</b>Both the mRNA and protein expression levels of RGN and PHB were significantly lower in the liver tissues of the fibrosis group than in the control group.CGII intervention led to significant alleviation of the liver fibrosis severity; moreover, the mRNA and protein expression levels of RGN and PHB were significantly higher than those in the fibrosis group.</p><p><b>CONCLUSION</b>Down-regulation of regucalcin and prohibitin gene expression might contribute to the pathogenesis of liver cirrhosis.</p>

<p><b>OBJECTIVE</b>To investigate the relationship between serum sex hormone levels, liver function, and pathogenic mechanisms related to cutaneous lesions involving the facial skin in male patients with liver cirrhosis.</p><p><b>METHODS</b>Fifty male cirrhotic patients with facial skin lesions, including spider angiomas, angiotelectasis and special type rash, (mean age: 48.1 +/- 12.2 years) were randomly selected for study and enrolled as the case group. Thirty cirrhotic male patients without facial skin lesions (mean age: 44.5 +/- 11.7 years) were enrolled as the control group. Serum levels of luteinizing hormone (LH), follicular stimulating hormone (FSH), prolactin (PRL), estradiol (E2), progesterone (PRGE), and testosterone (T) were detected and compared between cases and controls by the t-test. All patients were sub-categorized according to severity of cirrhosis (Child-Pugh classification) and comparisons between cases and controls were carried out by single factor analysis of variance. Logistic regression modeling was used to evaluate whether the presence of skin lesions is related to changes in markers of liver impairment, including alanine aminotransferase (ALT), aspartate aminotransferase (AST), total bilirubin (TBil), serum albumin (Alb), prothrombin time (PT-SEC), creatinine (CREA), platelet count (PLT), and alcoholism.</p><p><b>RESULTS</b>In the cases with spider veins, LH level was significantly elevated (t = 2.01) and T level was significantly decreased (t = -2.20) (both, P less than 0.05 vs. controls). In the cases with telangiectasia, the LH level (t = 3.76, E2 (t = 2.08) and E2/T ratio (t = 2.98) were significantly elevated and T level was significantly decreased (t = -3.77) (all, P less than 0.05 vs. controls). In the cases with special type rash, FSH level was significantly elevated (t = 2.03) and T level was significantly decreased (t = -2.01) (both, P less than 0.05 vs. controls). In the case group, E2 levels decreased as severity of liver damage increased, while in the control group, E2 levels increased as severity of liver damage increased; however, the difference in average E2 values of the two groups did not reach statistical significance (P more than 0.05). In both cases and controls, the T levels were decreased as the severity of liver damage increased (F = 3.70, P less than 0.05). Multivariate logistic regression analysis showed that increased incidence of facial skin lesions is associated with alcoholism (odds ratio (OR) = 4.46, 95% confidence interval (CI) = 1.45-13.7, P less than 0.05) and elevated serum levels of AST (OR = 11.87, 95% CI = 1.24-113.1, P less than 0.05).</p><p><b>CONCLUSION</b>Alcoholism, impaired liver function, and perturbed levels of circulating sex hormones are associated with cirrhosis-related facial lesions and may play important roles in the pathogenesis of cutaneous lesions in patients with cirrhosis.</p>

<p><b>OBJECTIVE</b>To evaluate the effect of CYP11B2 gene -344T/C polymorphism on renin-angiotensin-aldosterone system (RAAS) activity and blood pressure in response to hydrochlorothiazide (HCTZ) treatment in Han Chinese patients with essential hypertension.</p><p><b>METHODS</b>Eight hundred and twenty-nine patients with mild/moderate essential hypertensive were enrolled. All subjects had their antihypertensive medications withdrawn. After two weeks of wash-out period with placebo, each patient was given 12.5 mg of HCTZ per day for the next six weeks. Physical, biochemical measurements, and the activity of RAAS were taken at the end of the wash-out period (baseline) and 6-week diuretic therapy period. Changes in systolic and diastolic blood pressure were analyzed for association with interaction between genotypes at CYP11B2 -344T/C polymorphism and gender.</p><p><b>RESULTS</b>A total of 776 patients completed the study. 17.5% of subjects have achieved blood pressure normalization after six weeks treatment. For male patients, the aldosterone level with CC genotype was significantly higher than that of those with TT or TC genotype. Following the HCTZ treatment, the blood pressure response in patients with CC genotype was less obvious than that in others, whilst the increase of aldosterone level was greater. For female patients, no association was found between CYP11B2 -344T/C polymorphism and aldosterone level. Following the HCTZ treatment, the blood pressure response in patients with CC genotype was greater than others, whilst the increase of aldosterone activity was less apparent.</p><p><b>CONCLUSION</b>In males, the -344T/C polymorphism of CYP11B2 gene is associated with aldosterone level, and the change of aldosterone level was greater, the blood pressure response was weaker after HCTZ treatment. In females, there was no association between this polymorphism and aldosterone level. The change of aldosterone level and blood pressure response to HCTZ were different from that in males.</p>

<p><b>OBJECTIVE</b>To study the protective effects of blueberry against rat immune hepatic fibrosis, specifically through the expression of hepatic cytochrome P450 2E1.</p><p><b>METHOD</b>Fifty Wistar rats were randomly divided into five study groups (n = 10 each): Group A: normal control group, Group B: hepatic fibrosis model group, Group C: preventive group administered blueberry juice, Group D: preventive group administered Fu-Fang-Bie-Jia-Ruan-Gan tablet, and Group E: preventive group administered a combination of blueberry juice and Fu-Fang-Bie-Jia-Ruan-Gan tablet. The hepatic fibrosis model was established by intraperitoneal injection of porcine serum once daily for 12 weeks. Simultaneously, rats in preventive groups (Groups C-E) were perfused with blueberry juice or Fu-Fang-Bie-Jia-Ruan-Gan tablet or combinations of blueberry juice and Fu-Fang-Bie-Jia-Ruan-Gan tablet, respectively, for 12 weeks. The normal control group was perfused with saline for 12 weeks. All animals were sacrificed at the end of the 12 weeks, and serum levels of alanine aminotransferase (ALT) were measured and activities of superoxide dismutase (SOD), malondialdehyde (MDA), and hydroxyproline (Hyp) in liver homogenates were determined. Pathology of hepatic fibrosis was evaluated by hematoxylin-eosin (HE) and Masson staining. Expression of CYP2E1 was detected by real-time RT-PCR, immunohistochemical techniques, and Western blotting.</p><p><b>RESULTS</b>Serum ALT levels were not significantly different in the control and treatment groups (F=4.056, P more than 0.05): A: 37.87+/-4.53 U/L, B: 49.23+/-9.81 U/L, C: 39.94+/-6.32 U/L, D: 40.50+/-5.70 U/L, and E: 38.24+/-8.43 U/L. Compared with Group B, the pathological stages of hepatic fibrosis were significantly reduced in the prevention groups (C-E) (F=95.097, P less than 0.05). Hyp and MDA in liver homogenates of groups C-E were significantly lower than those of Group B (Hyp: C: 472.68+/-44.14 mug/g, D: 416.12+/-39.38 mug/g, E: 429.51+/-55.14 mug/g vs. B: 603.16+/-68.92 mug/g, F=39.315, P less than 0.05; MDA: C: 0.83+/-0.06 nmol/mg, D: 0.96+/-0.08 nmol/mg, E: 0.85+/-0.06 nmol/mg vs. B: 1.24+/-0.15 nmol/mg, F=46.376, P less than 0.05). In contrast, SOD activities in Group C-E were significantly higher than those in Group B (C: 2.47+/-0.38 U/mg, D: 1.95+/-0.45 U/mg, E: 2.16+/-0.23 U/mg vs. B: 1.56+/-0.41 U/mg, F=25.557, P less than 0.05). Compared with Group A, the mRNA and protein expressions of CYP2E1 were increased in groups B-E, however the differences did not reach statistical significance (mRNA: F=0.897, protein: F=0.492, both P more than 0.05). The mRNA and protein expressions of CYP2E1 in groups C-E were lower than those of Group B, however the differences did not reach statistical significance (mRNA: F=0.897, protein: F=0.492, P more than 0.05).</p><p><b>CONCLUSION</b>Blueberry exhibits certain protective effects against porcine serum-induced hepatic fibrosis in rats. The expression of hepatic cytochrome P450 2E1 in rats with immune hepatic fibrosis is not significantly different from the normal rats. Blueberry has no effect on the expression of hepatic cytochrome P4502E1.</p>
