Objective To investigate the clinical diagnostic value of extra-spindle pole-like protein 1(ESPL1)in the progression of hepatitis B virus(HBV)-related liver fibrosis.Methods A total of 228 patients with HBV infection who were admitted to The First Affiliated Hospital of Guangxi Medical University from June 2017 to August 2023 were enrolled.The transient elastography system FibroScan was used to determine liver stiffness measurement(LSM)for all patients,and according to the LSM value,they were divided into non-liver fibrosis group with 80 patients,mild liver fibrosis group with 83 patients,advanced liver fibrosis group with 30 patients,and liver cirrhosis group with 35 patients.ELISA was used to measure the serum level of ESPL1.The Kruskal-Wallis H test was used for comparison of the serum level of ESPL1 between the four groups;the Spearman correlation analysis was used to investigate the correlation between ESPL1 and LSM;the receiver operating characteristic(ROC)curve was used to analyze the value of serum ESPL1 in predicting the progression of liver fibrosis.Results The liver cirrhosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group and the mild liver fibrosis group(both P<0.05),and the advanced liver fibrosis group and the mild liver fibrosis group had a significantly higher serum level of ESPL1 than the non-liver fibrosis group(both P<0.05).The correlation analysis showed that there was a positive correlation between serum ESPL1 and LSM in the patients with HBV infection and varying degrees of liver fibrosis(r=0.515,P<0.001).Serum ESPL1 had an area under the ROC curve(AUC)of 0.809 in predicting liver cirrhosis and an AUC of 0.638 in predicting advanced liver fibrosis,with a sensitivity of 87.5%and 100%,respectively,and a specificity of 59.7%and 31.3%,respectively.Conclusion There is a certain correlation between serum ESPL1 and HBV-related liver fibrosis,and higher serum ESPL1 may indicate a higher degree of liver fibrosis.Serum ESPL1 is expected to become one of the serum markers for assisting in the diagnosis of liver cirrhosis and an important clinical method for dynamically monitoring the progression of liver fibrosis in patients with HBV infection.

OBJECTIVE：To investigate the effects of the integration of field processing and decoction piece processing （hereinafter called “Integration”for short ）on chemical composition of Ligusticum chuanxiong decoction pieces. METHODS ：Fresh L. chuanxiong were collected from Dujiangyan and Pengzhou of Sichuan ；integrated decoction pieces of L. chuanxiong were prepared after washing ，drying in the shade （to about 28％ moisture content ），slicing and drying ；traditional decoction pieces was prepared after drying in the shade ，adding water to moisten （to the core ），slicing and drying. HPLC fingerprints of two kinds of decoction pieces samples （with 10 batches in each type ）were established. The determination was performed on WondaSil C 18 column with mobile phase consisted of 1％ formic acid solution-acetonitrile （gradient elution ）at the flow rate of 1.0 mL/min. The column temperature was 30 ℃. The detection wavelength was set at 285 nm，and the sample size was 10 μL. Using ligusticolide A as reference ，HPLC fingerprints of 20 batches of samples were drawn. The similarity of the fingerprints was evaluated with Similarity Evaluation System for Chromatographic Fingerprint of TCM （2004A edition ），and then common peaks were confirmed. The contents of chlorogenic acid ，ferulic acid and ligusticolide A were determined by above chromatographic condition. Single factor variance analysis was performed for comparison of the contents. RESULTS ：The similarity of HPLC fingerprints among 20 batches of samples was above 0.900. A total of 16 common peaks were determined ，7 of which were chlorogenic acid ，ferulic acid，ligusticolide Ⅰ，pine cypress ferulinate ，ligusticolide A ，n-butylphthalide and ligustilide ，respectively. The linear range of chlorogenic acid ，ferulic acid and ligusticolide A were 0.008-0.200 mg/mL（r＝0.999 9），0.010-0.140 mg/mL（r＝0.999 2）and 0.100-0.600 mg/mL（r＝0.999 3）；the limits of quantification were 0.002 8，0.000 6 and 0.005 0 mg/mL，respectively；the limits of detection were 0.000 8，0.000 1 and 0.001 0 mg/mL，respectively；RSDs of precision ，reproducibility and stability tests were all lower than 3％，and average recoveries were 96.27％-102.02％（RSD＜2％，n＝6）. The contents of above compositions in the integrated decoction pieces and traditional decoction pieces were（1.677 0±0.311 0），（1.562 7±0.124 5），（9.494 0±1.351 3）mg/g and（1.300 2±0.469 2），（1.388 0±0.209 9），（9.811 7±1.098 9）mg/g，respectively；there was no statistical significance between 2 groups（P＞0.05）. CONCLUSIONS ：The chemical composition of each batch of samples of L. chuanxiong integrated decoction pieces and traditional decoction pieces is consistent ，and the content of index components as chlorogenic acid ，ferulic acid and ligusticolide A in the decoction pieces is not affected by the integration processing. This process is feasible to a certain extent.

Objective: To investigate the current status of fear of cancer recurrence in bladder cancer patients, and to explore the correlation between fear of recurrence and quality of life. Methods: A total of 96 bladder cancer patients were recruited by convenience sampling method from April 2017 to July 2017. They were investigated through general information questionnaire, Chinese version of Fear of Progression Questionnaire Short Form and Functional Assessment of Cancer Therapy-Bladder cancer form respectively. Results: The total score of fears of recurrence was 28.76±10.33, the total score of quality of life was 123.66±20.63. A total of 28 patients had a dysfunctional level of fears of recurrence (total score ≥34), the incidence was 29.2% (28/96). There were significant differences in the total scores of fears of recurrence at different ages, fears of recurrence were not related to another sociodemographic factors (gender, educational attainment and income) or disease, treatment related factors. The total scores of fears of recurrence and the total score of quality of life showed a high degree of negative correlation (r=-0.726, P < 0.01), the quality of life in physical, social and family, emotional, functional well being were negatively correlated with fears of recurrence (r=-0.841--0.592, P < 0.01). Conclusions Bladder cancer patients have a higher incidence of fears of recurrence and had an impact on quality of life from the physical, psychological and social domains, nurses should perceive the fears of recurrence of patients as soon as possible and give corresponding intervention measures to improve the quality of life of bladder cancer patients.

Objective:To identify the healing effect of electrospun silk fibroin-BMP-2 as a biologic pulp capping agent to inflammatory pulp in rat caused by lipopolysaccharide ( LPS) .Methods:A total of 30 healthy adult male Wistar rats were randomly divided into five groups:(1) normal control group without operation;(2) blank control group without capping agents;(3) calcium hydroxide capping group;(4) electrospun silk fibroin capping group;(5) electrospun silk fibroin-BMP-2 capping group .Bilateral up-per first molars of each rat in group 2-5 were drilled to expose the pulp to LPS which was used to estab-lish a model of inflammatory pulp .The exposed pulp was capped with different capping agents or without capping agents.Then the hole was sealed.The animals were sacrificed on days 3, 7, and 14 post-opera-tion and histological analysis was carried out , including HE stain and CD 14 immunohistochemical stain . Results:On day 7 and 14 , the lowest inflammatory reaction score in HE stain among pulp capping groups was that of silk fibroin-BMP-2 group .The next were calcium hydroxide group and silk fibroin group .That of blank control group was the highest .The ranking of reparative dentine scores of those groups was just reversed.The D values of immunohistochemical stain of CD 14 were not significantly different in groups applied pulp capping agents but significantly lower than blank control group on days 3 and 7.However, the D value of silk fibroin-BMP-2 group ( 0 .145 ±0 .011 ) was significantly lower than blank control group (0.287 ±0.019), calcium hydroxide group (0.170 ±0.017) and silk fibroin group (0.175 ± 0 .018 ) on day 14 .Conclusion:Electrospun silk fibroin compounded with BMP-2 promoted wound hea-ling of exposed pulp and had better potential to stimulate formation of reparative dentine to establish a suitable environment for pulp recovery .

Uncontrolled fibrosis of skin and internal organs is the main characteristic of scleroderma, and collagen is a major extracellular matrix protein that deposits in the fibrotic organs. As the chaperone of collagen, heat shock protein 47 (HSP47) is closely related with the development of fibrosis. To explore the potential function of HSP47 in the pathogenesis of scleroderma, the clinical, in vivo and in vitro studies were performed. In clinical, the increased mRNA level of HSP47 was observed in the skin fibroblasts and PBMC from scleroderma patients, and the enhanced protein level of HSP47 was also detected in the skin biopsy and plasma of the above patients. Unexpectedly, the enhanced levels of HSP47 were positively correlated with the presence of anti-centromere antibody in scleroderma patients. Moreover, a high expression of HSP47 was found in the skin lesion of BLM-induced scleroderma mouse model. Further in vitro studies demonstrated that HSP47 knockdown could block the intracellular and extracellular collagen over-productions induced by exogenous TGF-β. Therefore, the results in this study provide direct evidence that HSP47 is involved in the pathogenesis of scleroderma. The high expression of HSP47 can be detected in the circulatory system of scleroderma patients, indicating that HSP47 may become a pathological marker to assess the progression of scleroderma, and also explain the systemic fibrosis of scleroderma. Meanwhile, collagen over-expression is blocked by HSP47 knockdown, suggesting the possibility that HSP47 can be a potential therapeutic target for scleroderma.
