Objective:To determine the basic characteristics and clinical manifestations of hospitalized patients with psoriasis in Hunan, and to provide reasonable reference for the etiology and treatment of psoriasis.
Methods:Totally 190 patients with psoriasis from January 1, 2012 to December 31, 2012 treated in the Department of Dermatology, the Second Affiliated Hospital of Central South University were retrospectively analyzed. The data were analyzed by SPSS17.0.
Results:The ratio of male to female inpatient numbers was 3.13:1, aged was between 40 and 70 years. The most common subtype of psoriasis was psoriasis vulgaris (64.73%), followed by psoriatic erythroderma (18.42%). The distribution of the subtype of psoriasis did not differ by gender. Nineteen patients recalled clearly the cause of proriasis, 5 of which were caused by medicine, and 4 by drinking. Totally 96 cases accompanied with other diseases, 24.21%of which accompanied with cardiovascular system disease.
Conclusion:There is no season difference in the hospitalization of patients with psoriasis. there are more male than female inpatients. Treatment of psoriasis should consider clinical classification, drug adverse reactions, and individual factors for individual treatment.

Background::Evaluating the impact of digestive system diseases is vital for devising effective prevention strategies. However, comprehensive reports on the burden of digestive system diseases in China are lacking. Our study aimed to provide an overview of the burden and trends of digestive system diseases from 1990 to 2019 in China and its provinces.Methods::This cross-sectional study utilized the Global Disease Burden Study 2019 to estimate the incidence, mortality rate, disability-adjusted life years (DALYs), years of life disability, years of life lost, and changes in the burden of digestive diseases across Chinese provinces from 1990 to 2019. The analysis of disease burden primarily examines the characteristics of sub-disease distribution, time trends, age distribution, and sex distribution. Additionally, we compared provincial age-standardized DALYs for digestive diseases with the expected rates based on the socio-demographic index (SDI).Results::In 2019, there were 499.2 million cases of digestive system diseases in China, resulting in 1,557,310 deaths. Stomach cancer, colon and rectal cancer, and esophageal cancer are the top three diseases associated with mortality and DALY related to digestive system diseases. Meanwhile, cirrhosis and other chronic liver diseases, gastroesophageal reflux disease, and gallbladder and biliary diseases are the top three kinds of diseases with the highest prevalence among digestive system diseases. The risk of gastric cancer sharply increases among men after the age of 40 years, leading to a significant disparity in burden between men and women. As the SDI increased, the DALYs associated with digestive system diseases in China and its provinces showed a downward trend.Conclusion::Our study highlights the inverse correlation between DALYs associated with digestive system diseases and the SDI.

Polyhydroxyalkanoates (PHA) is a family of microbially synthesized polyesters consisting of various 3-hydroxyalkanoate monomers. Aeromonas hydrophila 4AK4 could be able to synthesize PHA copolymer consisting of 3-hydroxybutyrate (3-HB) and 3-hydroxyhexanoate (3-HHx). No data has been reported about the ability to synthesize the PHA with other monomers in A. hydrophila. In this study, propionic acid, valeric acid, heptanoic acid, nonanoic acid and undecanoic acid were used together with gluconate to find out whether A. hydrophila 4AK4 could synthesize the PHA consisting of odd carbon atom number monomers. The result showed that A. hydrophila 4AK4 could not growth when supplied with propionic acid, valeric acid, heptanoic acid and nonanoic acid and only undecanoic acid could be used to synthesize PHA. Wild type and recombinant A. hydrophila 4AK4 harboring phaA (beta-ketothiolase) and phaB (acetoacetyl-CoA reductase) were cultivated with undecanoic acid and glucose or undecanoic acid and gluconate served as carbon sources. PHA consisting of 3-HB and 3-hydroxyvalerate (3-HV) could be produced by both wild type and recombinant A. hydrophila 4AK4 and the latter could produce PHA with more 3-HB monomer. When the ratio of glucose or gluconate to undecanoic acid was 1:1, the cell dry weight (CDW) of A. hydrophila 4AK4 reached 1.14 g/L and PHA content was 60% of the CDW after cultivation for 24 h. When lauric acid and undecanoic acid were served as co-substrate, A. hydrophila 4AK4 could produce copolyester consisting of 3-HB, 3-HV and 3-HHx. Along with the increase of undecanoic acid proportion in the mixed carbon source, the 3-HV content of copolymer was increased while the 3-HB and 3-HHx content were decreased. In all cases, the CDW decreased along with the increase of undecanoic acid concentration, which indicated that undecanoic acid was not very good for A. hydrophila 4AK4 growth.

Flavonol synthase (FLS) is one of the key enzymes in flavonoids metabolic pathways. In this study, middle sequence was obtained from Carthamus tinctorius transcriptome sequencing results. Full-length cDNAs of FLS was cloned from petals of C. tinctorius to FLS by using RT-PCR and RACE technology. Its full-length cDNA was 1,201 bp, with an open reading frame of 1,101 bp and 336 encoded amino acids. The phylogenetic analysis showed that, FLS gene encoded amino acids in C. tinctorius were highly homologous with amino acids in congeneric Compositae species, especially Rudbeckia laciniata. The pBASTA-FLS plant expression vector was successfully built by the molecular biology method, which lays a foundation for further studying biology functions of the gene and biosynthesis mechanism of flavonoids.

Objective:To explore the clinical efficacy of CT-guided 125I radioactive seed implantation in the treatment of bone metastases. Methods:The data of 43 patients with bone metastases treated by seed implantation from June 2016 to July 2018 in the 3201 Hospital was retrospectively analyzed. The 52 lesions of 43 patients with bone metastases were treated with 125I radioactive seed implantation. The patients were followed up, and the efficacy was evaluated based on pain relief, quality of life improvement, and whole body bone imaging. Results:The number of pain relief patients in 43 patients with bone metastases at 1, 3, 7, 30, 60, 90, and 180 d after 125I radioactive seed implantation were 19, 32, 39, 36, 36, 34, and 31 cases; the pain relief rates were 44.19%, 74.28%, 90.70%, 83.72%, 79.07%, and 72.09%, respectively. The pain relief rate was highest at 7 d after seed implantation, and the pain degree after seed implantation was significantly lower than that before seed implantation, the difference was statistically significant (Z = -5.216, P < 0.05). The difference in quality of life between patients before and after 125I radioactive seed implantation was statistically significant (Z = -4.308, P < 0.05). The re-examination in 3 to 6 months after treatment showed that the metabolism of 45 bone metastases lesions was reduced and shrunk, and the efficiency rate was 86.54% (45/52). Conclusion:125I radioactive seed implantation has good curative effect in the treatment of patients with bone metastases, which can effectively relieve pain, improve local control rate, and improve patients' quality of life.

Objective: The study aims to examine the prospective association and sex differences of pubertal timing and tempo with behavior problems. Methods: Participants from two primary schools in grade 1-3 were selected through clustering convenience sampling method in Bengbu, Anhui Province was established since 2013 (T1), with informed consent, 2 084 students were recruited, and follow-up surveys were conducted in 2015 (T2), 2017 (T3) and 2019 (T4) respectively. Demographic information, non-suicidal self-injury (NSSI), suicidal ideation, suicide plan, suicide attempt and externalizing symptoms were collected through questionnaire investigation, and pubertal development in boys and girls were evaluated by secondary sexual development (testicular volume for boys and breast development for girls). At T4, externalizing symptoms were evaluated by MacArthur Health & Behavior Questionnaire-Child (HBQ-C). Using SAS PROC NLMIXED to fit nonlinear growth model to estimate pubertal timimg and tempo. Puberty timing was classified into early, on-time, and delayed groups; and the puberty tempo into fast, average, and slow groups. Multivariable logistic regression model was used to analyze the predictive effects of modeling pubertal timing and tempo on multi-disciplinary behavior problems in adolescence boys and girls. Results: There were 1 909 people with complete baseline and follow-up questionnaires and puberty development information. Reported rates of externalizing symptoms, NSSI, suicidal ideation, suicide plan, suicide attempt and were 13.9% (265), 24.4% (466), 14.2% (271), 4.6% (88) and 2.3% (43) respectively. Logistic regression analysis results show that fast pubertal tempo increases the risk of externalization [OR(95%CI)=2.85(1.53-5.31) and NSSI [OR(95%CI)=2.11(1.22-3.65)] for boys, and the risk of suicide attempt [OR(95%CI)=2.99(1.07-8.35)] for girls. Slow tempo can reduce the risk of suicidal ideation and suicide plan for boys [OR(95%CI)=0.40(0.18-0.87), 0.07(0.01-0.67)], the externalizing symptoms and suicidal ideation for girls [OR(95%CI)=0.33(0.13-0.81)，0.38(0.17-0.85)]. Early pubertal timing will increase the risk of suicide plan for boys [OR(95%CI)=3.60(1.04-12.43)], meanwhile late timing can reduce the risk of NSSI in girls [OR(95%CI)=0.39(0.19-0.80)]. Conclusion The tempo of pubertal development may be a useful predictor of adolescent behavioral problems.

OBJECTIVETo investigate the water intake sources of adults in the four cities of China in summer.

METHODSA total of 64 adults aged 18 - 60 yrs from the four cities (Beijing, Shanghai, Chengdu and Guangzhou) were selected using convenient sampling method. The information on amounts and types of daily drinking water was recorded by subjects for three consecutive days using a quantitative measurement. The food samples were collected by using duplicate portion method and the water content of food samples were determined.

RESULTSThe median of daily total water intake of 63 subjects was 3045 ml, while daily total drinking water was 1600 ml, the median ratio of which accounting for 55.8% of total water intake. Water from food was 1157 ml, the median ratio of which accounting for 41.4% of total water intake. The median of daily total water intake (3566 ml) and the ratio of water from food (55.3%) of subjects in Chengdu was significantly higher than subjects in Guangzhou (2929 ml, 45.4%), Shanghai (2748 ml, 33.1%) and Beijing (2743 ml, 31.3%) (daily total water intake: χ² = 10.42, P = 0.015;the proportion of water: χ² = 28.48, P < 0.01). Daily total water intake in men (3302 ml) was significantly higher than that in women (2900 ml) (Z = 2.35, P = 0.019).

CONCLUSIONDaily total water intake of subjects in summer was more than the current Chinese recommended total water intake (2200 ml), with the main part of drinking water and water from food.

BACKGROUNDIdiopathic pulmonary fibrosis (IPF) is a progressive diffuse parenchymal disease with a poor prognosis. A variety of cytokines and chemokines are involved in its pathophysiology. The aim of this study was to evaluate the clinical features in IPF patients with the expression of suppressor of cytokine signaling 1 (SOCS-1), which acts as a negative regulator of cytokine signaling.

METHODSIPF patients (n = 20) and healthy controls (n = 16) were included in this study. The expression of SOCS-1 was analyzed in peripheral blood mononuclear cells (PBMC) of subjects using RT-PCR. Interleukin 4 (IL-4), transforming growth factor β1 (TGF-β1) and type I collagen expression were also analyzed in each individual using enzyme-linked immunosorbent assay (ELISA). The clinical characteristics of IPF patients were delineated. These results were analyzed by SPSS13.0 statistics software.

RESULTSSOCS-1 mRNA expression was significantly decreased in the PBMC of IPF patients compared with healthy controls; serum levels of IL-4 and TGF-β1 were higher in IPF patients. The patients with lower expression of SOCS-1 developed lower percentage of forced vital capacity (FVC%) and DLCO/VA. A patients' SOCS-1 mRNA level was negatively correlated with serum levels of IL-4, and negatively correlated with their high-resolution computed tomography (HRCT) scores.

CONCLUSIONSSOCS-1 mRNA can be detected in PBMC, and it is down-regulated in IPF patients. The expression of SOCS-1 is associated with the severity of IPF patients' symptoms, so it might be the predictor of disease severity. SOCS-1 might play an important role in IPF by reducing the expression of the T helper type 2 (Th2) cell-related cytokine IL-4.
