OBJECTIVE:To study the protective effect of oral Yihuang liquor on the immune liver injury of mice METHODS:The mouse models were established by injecting BCG+LPS qd through caudal veins on 10 successive days,then Yihuang liquor was given to mice through gastric tube The serum ALT,AST and weight of liver and spleen were determined,and the pathological changes of the liver were observed under light microscope before and after administration of Yihuang liquor RESULTS:Yihuang liquor in a large dose or middle dose could markedly decrease the levels of serum ALT and AST,lessen the swelling of liver and spleen,reduce the degeneration and necrosis of hepatic cells and inflammatory cell infiltration in portal area in mice with liver damage On one hand Yihuang liquor in a low dose could inhibit the immunofunction and alleviate delayed hypersensitive reaction in mice with normal or enhanced cellular immunofunction but on the other it could raise immunofunction and enhance the delayed hypersensitive reaction in mice with hypoimmunofunction CONCLUSION:Yihuang liquor can regulate cellular immunofunction and obviously protect the immune liver injury

ObjectiveTo measure levels of serum resistin in patients with nonalcoholic fatty liver disease (NAFLD) and explore the relationship between serum resistin and insulin resistance,and the role of serum resistin in the pathogenesis and progression of NAFLD.Methods 53 patients (including 30males and 23 females) with NAFLD and the 28 control subjects (including 16males and 12females) were enrolled in this study.The height,weight,waist circumstance,hip girth and blood pressure of all subjects were obtained by standard methods.To all the subjects,the parameters including fasting blood glucose (FBG),triglyceride ( TG),total cholesterol (TC),high-density lipoprotein cholesterol ( HDL-c ),lowdensity lipoprotein cholesterol ( LDL-c ),alanine aminotransferase ( ALT),aspartate aminotransferase (AST)and gamma glutamyl transferase (GGT) were measured.Serum resistin was measured by electrochemiluminescence immunoassay (ECLIA) and fasting serum insulin (FINS) were measured by enzymelinked immunosorbent assay (ELISA).Body mass indexes (BMI),waist hip ratio (WHR),body fat percentage ( BF％ ) were calculated with formula.Homeostasis model assessment was applied to assess the status of insulin resistance index (HOMA-IR).The relationships between serum resistin and various parameters in patients with NAFLD were observed and analyzed by statistical methods.ResultsThere were no significant differences in the number of cases,average age,compositions of sex and BF％ between the NAFLD group and the control group ( P ＞ 0.05).In the NAFLD group,systolic blood pressure ( SBP),diastolic blood pressure(DBP).The waist circumference,hip girth and BMI and WHR were higher than those of control group ( t =3.54,3.32,3.56,5.85,5.56,4.10,P =0.001).There were no significant differences on the level of TC,HDL-c,LDL-c between the NAFLD group and the control group ( P ＞0.05).In the NAFLD group,FBG,TG,AST were higher than those of control group ( P =0.001,P =0.004,P =0.001 ).The levels of serum resistin,FINS,HOMA-IR,ALT and GGT in NAFLD group were significantly higher than those of control group,and there was significant difference between two groups ( P =0.0005).There was no significant correlation between serum resistin and age,BMI,WHR,BF％,FBG,TG,TC,HDL-C,LDL-C,AST in NAFLD group ( P ＞ 0.05).The levels of serum resistin in patients with NAFLD were positively correlated with GGT,ALT,FINS,HOMA-IR ( r =0.354,0.391,0.875,0.881,P ＜0.05 or ＜0.01 ).After multiple stepwise regression analysis,the results showed that HOMA-IR was the most important factor for affecting the levels of serum resistin.The levels of serum resistin in male and female patients with NAFLD were higher than those of control group ( P ＜0.05).But no statistical difference was found between males and females in two groups ( P ＞ 0.05).ConclusionsThe levels of serum resistin in patients with NAFLD were significantly higher than those of controls.Serum resistin in patients with NAFLD was closely correlated with insulin resistance,and it may participate in the pathogenetic progress of NAFLD.Serum resistin in patients with NAFLD might be associated with hepatic insulin resistance,and it has no correlations with obesity-related insulin resistance.Serum resistin in patients with NAFLD may participate in the inflammation of fatty liver disease as inflammatory cytokines.

Objective To investigate the expression of human defensin-alpha1-3 (HNP1-3) in breast cancer and in normal tissues and determine whether there exists a relationship between HNP1-3 expression and clinicopathologic features.Methods Immunohistochemical staining was used to detect the expression levels of HNP1-3 in 59 breast cancer specimens,and 20 normal tissues (fibroadenoma of breast or tumor-adjacent tissues).The relationship of the expression levels of HNP1-3 with patient’s age,clinical stage,histological grade,lymph node metastases and expression of PR/ER/C-erB-2 was analyzed.Results High level expression of HNP1-3 (95%) was expressed in those normal breast tissues.Different expression of HNP1-3 was found in breast cancer specimens and closely correlated with tumor histological stage and lymph node metastases (P

AIM: To study the efficacy and safety of Ultra Q- YAG vitreolysis for vitreous floaters.
METHODS: Retrospective case series study. From September 2014 to May 2015 in Beijing Aier - Intech Eye Hospital, 263 cases (340 eyes) with vitreous floaters were involved. All patients underwent visual acuity, intraocular pressure, slit lamp, mydriatic fundus, B ultrasonic examination, and recorded the form of a vitreous opacity excluded pathological fundus lesions. All the patients were divided into two groups: Group A (<30 years old) 78 cases (82 eyes); the morphology of vitreous opacity were dot, filiform and mesh. Group B ( > 45 years old), 185 cases (258 eyes), the morphology of vitreous opacity was Weiss ring, translucent flocculent clouds or dense fibrous membrane. Patients in 30 - 45 years old were eliminated because of the untypical opacity factor. The treatment was done by the same physician. Vision changes was analyzed before and after the treatment.
RESULTS: Questionnaire survey was done. According to the scores of the questionnaires, patients were divided into 3 groups: no improvement ( 1 - 2 points), partial improvement (3-5 points), significant improvement (6-10 points ). At 1mo after treatment, Group A: no improvement in 9 eyes (11. 0%), partial improvement in 57 eyes (69. 5%) and significant improvement in 16 eyes (19. 5%); Group B: no improvement in 0 eyes, partial improvement in 23 eyes ( 8. 9%) and significant improvement in 235 eyes (91. 1%); all the patients had no complications.
CONCLUSION: The treatment with YAG vitreolysis for vitreous floaters is safe and effective, especially for the patients more than 45 years old whose vitreous floaters caused by posterior vitreous detachment.

Objective:To investigate the efficacy and major adverse cardiovascular events(MACE)in elderly patients with ischemic cardiomyopathy-induced heart failure with reduced ejection fraction(HFrEF)treated with Sacubitril-valsartan at 3 years of follow-up.Methods:This was a single-center retrospective cohort study.The elderly patients with ischemic cardiomyopathy-induced HFrEF aged 60-85 years were diagnosed and treated in Beijing Anzhen Hospital from January 2018 to January 2020.A total of 120 continuously included elderly HFrEF patients treated with sacubitril valsartan were enrolled as the observation group, and 120 age-, gender-and B-type natriuretic peptide-matched elderly HFrEF patients treated with angiotensin converting enzyme inhibitor/angiotensin receptor blocker(ACEI/ARB)were enrolled as the control group.Structure and function of the heart were detected at 1-year follow-up.The MACE was observed, including cardiogenic death, readmission due to heart failure worsening and malignant arrhythmia at 3-year follow-up.Results:During follow-up(23.5±11.6)months, the visit of 18 cases was lost.There were no significant differences in the age, medical history, blood pressure between the two groups( P>0.05). Follow-up results showed that the improvement was better in observation group than in control group as follows: the left ventricular ejection fraction(45.8±9.4)% vs.(40.7±8.5)%, left ventricular end-diastolic diameter(56.5±8.3)mm vs.(59.2±7.3)mm, left ventricular end-systolic diameter(42.5±11.2)mm vs.(45.7±9.6)mm, left atrium inner diameter(49.1±8.7)mm vs.(51.2±7.7)mm, and left ventricular mass index(111.3±34.3)g/m 2vs.(119.7±31.5)g/m 2( t=4.41, 2.68, 2.38, 1.98 and 1.98, respectively, P<0.01 or 0.05). The rates of readmission due to heart failure worsening and the incidence of MACE were lower in the observation group than in the control group(21.7% or 26/120 vs.36.7% or 44/120, and 45.0% or 54/120 vs.71.7% or 86/120, χ2=6.54 and 17.55, P<0.05 or 0.01). In patients with the grade Ⅲ and Ⅳ New York Heart Association(NYHA)cardiac function, the incidence of MACE were lower in the observation group than in the control group(75.0% or 9/12 vs.100.0% or 14/14, χ2=5.10, P<0.05). Conclusions:Sacubitril-valsartan can improve cardiac structure and function, and decrease the incidence of MACE in elderly patients with HFrEF induced by ischemic cardimyopathy.

OBJECTIVE:To investigate the effects of Periplogenin, a compound extracted and purified from traditional Chinese medicine Cortex Periplocae, on mast cell degranulation and histamine release in mice and rats. METHODS: Sensitization was induced by injecting pertussis vaccine injected in rats' abdominal cavity and ovalbumin injected in mice's hind leg to detect mast cell degranulation reaction and prepare anti-serum; rats were injected intraperitoneally with the diluted serum sample taken form sensitized rats to detect mast cell degranulation reaction; and the concentration of histamine was determined by fluorescence spectrophotometry. RESULTS: Periplogenin showed significant inhibitory effect on histamine release of mast cell cultured in vitro, and at experimental dose it could decrease histamine release by(69.4?8.6)% in an obvious dose-depe-ndent manner. Periplogenin also showed obvious inhibitory effect on histamine release of mast cells in antigen-sensitized rats,and at a concentration of 20 ?g?mL-1,it could decrease histamine release by 73.55%, and at an oral dose of 50 mg?kg-1, it could dose-dependently reduce histamine release by above 80% in sensitized rats. CONCLUSION: Periplogenin showed significant inhibitory effects on histamine release of mast cells either cultured in vitro or in antigen-sensitized rats. Oral administration of Periplogenin can result in the significant reduction of histamine release of mast cells in rats. In view of the role that the mast cell histamine release and degranulation play in inflammation reaction, periplogenin can be regarded as one of the active anti-inflammation components of traditional Chinese medicine Cortex Periplocae.
