Abstract: Objective To explore the value of real-time shear wave elastography in evaluating the severity of liver fibrosis in hepatitis B, and to analyze the factors that affecting its accuracy. Methods A total of 196 chronic hepatitis B patients, who admitted to the Third Affiliated Hospital of Chengdu Medical College from February 2018 to October 2020, were selected for retrospective analysis. Demographic indicators such as gender, age, body mass index(BMI), and laboratory indicators such as fasting blood glucose, liver function, and blood lipid composition were collected. The patients were detected by real-time shear wave elastography. Taking the pathological test results as the gold standard, the diagnostic value of real-time shear wave elastography in the severity of liver fibrosis in chronic hepatitis B was analyzed, and the comprehensive effect of various factors on the diagnostic accuracy of real-time shear wave elastography was evaluated by Logistic regression analysis. Results The differences in real-time shear wave elastography of patients with different severity of liver fibrosis in hepatitis B were statistically significant, and F0 grade
2.Advances in the studies of platelet glycoprotein VI (GPVI): review.
Journal of Experimental Hematology 2006;14(5):1040-1044
Platelet glycoprotein VI (GPVI) is a major receptor for collagen on the platelet surface. It mediates the initial platelet contact with collagen, generates intracellular signals, increases the affinity of integrin receptor, and causes platelet aggregation and thrombosis. Suppression of GPVI function can significantly inhibit collagen-induced platelet adhesion, aggregation and thrombosis, so GPVI has become a novel target for antiplatelet therapy. Within the last few years, major advances have been made in understanding platelet-collagen interactions. In this paper, the advances of study on GPVI, including composition of GPVI, functions of GPVI, factors related with functions of GPVI, GPVI and clinic were summarized.

4.Skin tissue engineering in China.
Chinese Journal of Burns 2008;24(5):362-364
Great progress has been made in the basic research and clinical application of skin tissue engineering in China over the past 20 years. It includes culture of epithelial cells and their preliminary clinical use, research and development of various dermal substitutes such as acellular dermal matrix, spongiform collagen membrane and high molecular weight polymer membrane, and modification of physical properties of dermal substitutes for the sake of raising their bioaffinity and vascularization, based on which composite skin containing epithelial cell layers has been constructed and used successfully in the repair of full-thickness skin defects. More recently, greater efforts have been made in the study of new epithelial seeding cells such as epithelial stem cell and hair follicle stem cell. With the work going into the center, it is hopeful into constructing an artificial skin that mimics the normal human skin in terms of structure and function with better viability of the transplant, so that it can eventually be used in clinical practice as a skin source for large area deep burn patients to improve the wound healing quality.

OBJECTIVETo investigate the analgesic and sedative effects of inhaling a mixture of nitrous oxide and oxygen on burn patient during and after dressing change.
METHODSA total of 240 burn patients hospitalized in the Institute of Burn Research of Changhai Hospital Affiliated to the Second Military Medical University, Department of Burns of the First People's Hospital in Zhengzhou, and Department of Burns and Plastic Surgery of General Hospital of Ningxia Medical University from October 2011 to September 2012 were enrolled in our study, and they were all in accordance with the inclusion criteria. The 240 patients were divided into control group (n = 60, treated with inhalation of oxygen during dressing change) and treatment group (n = 180, treated with inhalation of a mixture of 65% nitrous oxide and oxygen during dressing change) according to the computer-generated list of random number. The other treatments in control group and treatment group were the same. Before, during, and after dressing change, heart rate (HR), systolic blood pressure (SBP), diastolic blood pressure (DBP), oxygen saturation (SO2), and adverse effects were observed. The degree of pain and anxiety felt by the patients were respectively evaluated with the visual analogue scale (VAS) and Chinese version of the burn specific pain anxiety scale (C-BSPAS) at the same time points as above. Data were processed with analysis of covariance, chi-square test, analysis of variance, and rank sum test.
RESULTSThere were no significant differences between control group and treatment group in the levels of HR, SBP, DBP, and SO2 before dressing change (with F values respectively 0.76, 0.06, 1.11, 0.70, P values all above 0.05). Compared with those of control group, the levels of HR, SBP, DBP, and SO2 in treatment group were significantly ameliorated during dressing change (with F values respectively 81.78, 146.36, 226.44, 205.62, P values all below 0.01). After dressing change, the levels of DBP in the two groups were close (F = 0.31, P > 0.05), but the levels of HR, SBP, and SO2 showed statistical differences (with F values respectively 7.02, 8.69, 12.23, P < 0.05 or P < 0.01). Before dressing change, the VAS scores were approximate between control group and treatment group (Z = 0.21, P > 0.05). Compared with those in control group (9.4 ± 0.7, 1.7 ± 2.5), the VAS scores were significantly lowered in treatment group during and after dressing change (1.6 ± 1.3, 0.7 ± 1.1, with Z values respectively 11.84, 3.35, P values all below 0.01). There was no significant difference in C-BSPAS score between control group and treatment group before dressing change (Z = 0.62, P > 0.05). Compared with those in control group (75 ± 13, 73 ± 12), the C-BSPAS scores in treatment group were decreased during and after dressing change (9 ± 15, 9 ± 14, with Z values respectively 11.91, 12.28, P values all below 0.01). There were no obvious adverse effects in two groups before, during, and after dressing change.
CONCLUSIONSA mixture of nitrous oxide and oxygen seems to have obvious analgesic and sedative effects on burn patients during dressing change, and it can be widely used.

Objective To investigate the characteristics and distribution of human eehinococcosis in Hobukesar Mongolian Autonomous County (HMAC) in Xinjiang. Methods Using cluster sampling methods, the 2 counties (Tiebukenwusa and Narenhebuke) in HMAC were chosen as focusing areas for investigation. A survey of human echinococcosis including questionnaire, serological test and abdominal ultrasonic scan was carried out. Results The prevalence of human echinococcosis was 9.0% (64/712) by ultrasound and surgical history, including 8.7% (62/712) for cystic eehinococcosis(CE), 0.3%(2/712) for alveolar echinococcosis(AE) and 15.6%(111/712) for total of serological positives in HMAC. CE prevalence rate of different occupations, age, family slaughtering livestock and drinking water source had significant differences(P<0.05). Herdsmen as the highest risk group showed a CE prevalence of the 13.4% (27/201) in comparison with other occupations. The ages between 20 to<40 year-old were at the highest risk stage with 12.8% incidence. But CE prevalence rate of different gender, ethnic and education groups had not significant differences(P>0.05). Conclusions HMAC could be considered as a high endemic human CE region in Xinjiang. The current study reported the main risk factors may include occupations, age difference and drinking water source.
