Objective To investigate the relationship between CT performance of Hver cirrhosis and liver fibrosis factors.Methods 89 hospitalized patients were graded for the CT performance of the liver cirrhosis:O class (have no cirrhosis),Ⅰ,Ⅱ,Ⅲ,Ⅳ class.Then to compare the examination data of senlm liver fibrosis factors:type Ⅲ procollagen(Prop),Ⅳ collagen(Ⅳ-C),laminin(LN),hyaluronie acid(HA).Results O class(have no cirrhosis in the sufferer):four index signs all has no increase.Ⅰ class:the Ⅳ-C slightly goes up.Ⅱ class:Ⅳ-C,the HA slishtly goes up.Ⅲ class:the three of Ⅳ-C,HA,LN rises,the HA is distinct.Ⅳ class:four index signs all go up obviously.Conclusion With the CT performance of liver cirrhosis is obvious,the hver fibrosis factors get obvious,too.Both of them get positive correlation.
4.Research progress in parathyroid hormone-related protein and diabetic nephropathy
Chinese Journal of Endocrinology and Metabolism 2014;30(11):1009-1011
Parathyroid hormone-related protein (PTHrP) and its receptor type 1 (PTH1 R) are extensively expressed in the kidney,where they are able to modulate renal function.Animal and human studies have shown that PTHrP acts as an important mediator of diabetic renal cell hypertrophy by a meehanism which involves the modulation of cell cycle regulatory proteins and TGF-β1.Furthermore,angiotensin Ⅱ (Ang Ⅱ) appears to be responsible for PTHrP upregulation in these conditions.These findings provide novel insights into the well-known protective effects of Ang Ⅱ antagonists in renal diseases,paving the wav for new therapeutic approaches.

Chinese Journal of Tissue Engineering Research 2007;0(50):-
BACKGROUND:When leucocytes were activated in the process of lung ischemia-reperfusion,various cell factors will be released,including tumor necrosis factor ?(TNF-?) and interleukin 1?(IL-1?),which lead to ischemia-reperfusion injury.Recent research demonstrates that transforming growth factor-?1 plays a protective role in ischemia-reperfusion injury after lung transplantation OBJECTIVE:To investigate the level changes of TNF-? and IL-1?after interfered with transforming growth factor-?1 after lung ischemic-reperfusion injury DESIGN,TIME AND SETTING:The randomized controlled experiment of animal was performed in the Cardiothoracic Surgery Laboratory of Changhai Hospital,Second Military Medical University of Chinese PLA from August to October 2007.MATERIALS:Thirty Sprague-Dawley rats with clean grade,were randomly divided into the sham operation,ischemia-reperfusion and transforming growth factor?1 groups,with 10 animal in each group.The transforming growth factor?1 was phuchased from Peprotech INC.METHODS:The left lung of rat in the ischemia-reperfusion and transforming growth factor?1 groups was prepared for to ischemia-reperfusion model by blocking pulmonary circulation with hilar vessels ligation for 60 minutes,followed by reperfusion for 2 hours.Animals in the sham operation group were crossed hilar with 10# silk thread.Heparin was administered intravenously through vena cervicalis at 15 minutes before ischemia in each group.Concurrently,10 ?g/kg transforming growth factor?1 was administered in transforming growth factor?1 group.MAIN OUTCOME MEASURES:After 2 hours of ischemia-reperfusion,the tissues of left lung were removed,histomorphological changes,wet-dry weight ratio,the index of histological lung injury and the content of TNF-?and IL-1?were determined by light microscope,enzyme-linked immunosorbent assay(ELISA),respectively.RESULTS:A total of 30 animals were enrolled in the result analysis.There was no obvious pathological change of lung in the sham operation group.Visible tissue edema and neutrophil infiltration could be found in the ischemia-reperfusion group,while,there was mild tissue edema and little neutrophil infiltration in the transforming growth factor?1 group.The wet-dry weight ratio and index of histological lung injury in the ischemia-reperfusion group was obvious greater than that of the sham operation group(P
6.Application of endoscopic ultrasonography in the diagnosis of early esophageal cancer
Journal of International Oncology 2021;48(3):176-179
Esophageal cancer is one of the most common malignant tumors in clinic, and its morbidity and mortality are always high. Staging is the main basis for comprehensive treatment and prognosis evaluation. Accurate staging is essential for proper diagnosis, individualized treatment and good prognosis. Related technologies of endoscopic ultrasonography can determine the depth of tumor invasion and local lymph node metastasis, which makes the diagnosis of esophageal cancer more accurate, and plays an increasingly important role in the diagnosis and treatment of early esophageal cancer.
7.Effects of Aerobic Exercise on Skeletal Muscle Glycogen and Exercise Endurance in Rats with Chronic Heart Failure
Chinese Journal of Rehabilitation Theory and Practice 2015;21(4):426-431
Objective To observe the effects of 8-week aerobic exercise on skeletal muscle glycogen content and exercise endurance and investigate the possible mechanism in rats with chronic heart failure. Methods 30 Sprague-Dawley rats were submitted to heart failure sedentary (H) group, heart failure traning (HT) group and sham operation (S) group. The heart failure model was established with coronary artery ligation. HT group performed an 8-week treadmill running. The skeletal muscle glycogen content was determined with anthracenone, exercise endurance with exhaust duration of graded exhausted exercise test, glucose uptake rate, activity of glycogen synthase (GS) and glycogen phosphorylase (GP) with radicisotope, protein expression of total GS, phospho-GS (p-GS), total GP and phospho-GP (p-GP) with Western Blotting. Correlation analysis was conducted between glycogen content and exhaust duration. Results The skeletal muscle glycogen, exhaust duration, glucose uptake rate, GS activity and p-GP protein reduced (P<0.05), while serum insulin, GP activity and p-GS protein raised (P<0.05) in the H group compared with those in the S group. The skeletal muscle glycogen, exhaust duration, glucose uptake rate, GS activity and p-GP protein increased (P<0.05), while serum insulin, GP activity and p-GS protein decreased (P<0.05) in the HT group compared with those in the H group. There was positive correlation between glycogen content and exhaust duration (P<0.05). Conclusion Prolonged aerobic exercise enhanced skeletal muscle glycogen content and exercise endurance in rats with chronic heart failure, which may be related to the improvement of insulin sensitivity, muscle glucose uptake, increase of glycogen synthesis and decrease of glycogen breakdown.

9.Methods that used to evaluate the visual quality after wearing orthokeratology lens
International Eye Science 2017;17(6):1090-1094
Orthokeratology is a kind of rigid contact lens which have reverse geometric desi, with higher oxygen permeability and security.Overnight wearing of orthokeratology can decrease the central corneal curvature and increase peripheral corneal curvature by flatting the central department of corneal, thus reduce the refraction of myopia.Through a period of time of wearing orthokeratology lens, patients can obtain good eyesight without frame glasses.Insisting on wearing orthokeratology lens can control the development of myopia.Orthokeratology is widely applied in the control of juvenile myopia, so we need scientific evaluation system to measure the visual quality after wearing orthokeratology lens.Here are the methods that used to evaluate the visual quality after wearing orthokeratology lens.
10.Effect of rigid gas permeable lens on the tear film and visual quality in adolescents
International Eye Science 2016;16(11):2099-2102
AIM:To evaluate the effect of rigid gas permeable ( RGP ) lens on the tear film and the visual quality in adolescents with a double-pass system.
METHODS:This was a prospective study comprised 23 myopia patients ( 39 eyes ) wearing rigid gas permeable contact lens ( RGP ) between Jun. 2015 and Aug. 2015 in the Department of Ophthalmology of Jinling Hospital. Uncorrected visual acuity ( UCVA ) , sphere refractive, cylinder refractive, Schirmer I test, tear film break-up time ( BUT ) , the visual quality and the tear film quality with OQAS II were obtained before and 1wk, 1, 3, 6mo after wearing. The data was analyzed using t-test and One-way.
RESULTS:The UCVA in before and after 1wk, 1, 3, 6mo were 0. 23±0. 10, 0. 81±0. 23, 0. 99±0. 11, 1. 01±0. 09, 0. 95±0. 14, the difference was statistically significant ( F=723. 36, P<0.01). The sphere in before and after 1wk, 1, 3, 6mo were (-2. 83±1. 34) D, (-0. 63±0. 82) D, (-0. 12±0. 20) D, (-0. 03±0. 10 ) D, (-0. 10±0. 30 ) D respectively, the difference was statistically significant (F=107. 01, P<0. 01). The refractive cylinder in before and after 1wk, 1, 3, 6mo were (-0. 12±0. 21) D, (-0. 13±0. 22) D, (-0. 12±0. 21) D, (-0. 14±0. 26) D, (-0. 21±0. 27) D respectively, there was no significant difference before and after wearing RGP (F=2. 58, P>0. 05). Schirmer I test showed no statistically significant difference before and after wearing RGP ( F=4.88, P>0. 05). The stability of tear film was reduced after wearing RGP, and the difference was statistically significant (F=135. 11, P<0. 01). The modulate transfer function ( MTF ) cut- off frequency was reduced after wearing RGP, the object scatter index ( OSI ) was increased after wearing RGP, and the difference was statistically significant, the tear film quality OSI was increased after wearing RGP, and the difference was statistically significant (F=6. 16, 19. 23, 10. 62, P<0. 01).CONCLUSION:The UCVA is significantly increased after wearing RGP. However, there was no significant change in the base-line of tear secretion, but BUT is significantly reduced after wearing RGP. The stability of the tear film is reduced, which can lead to a decline in visual quality.
