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

The clinical data of a patient with maturity-onset diabetes of the young 11 (MODY11) caused by B lymphocyte kinase( BLK) gene mutations in Children′s Hospital Affiliated to Nanjing Medical University in August 2018 were retrospectively analyzed.The diabetes mellitus epidemiologic investigation was carried out on the patient′s family.The 13-year-old boy was diagnosed with type 1 diabetes at the local hospital 6 months ago.Physical examination showed that he was 65.5 kg in weight, 169.2 cm in height and 22.9 kg/m 2 in the body mass index.He was overweight without acanthosis nigricans.Laboratory measurements revealed fasting blood glucose 11.79 mmol/L, fasting insulin 18.05 mmol/L, and fasting C-peptide 1.12 mmol/L.The glycosylated hemoglobin was 12.0%, while the islet antibodies were all negative.Among 4 consecutive generations of this family, 11 members presented with diabetes, 8 cases of who were treated with insulin and 3 cases with oral hypoglycemic drugs.The whole exome sequencing identified a heterozygous mutation in exon 9 of BLK (c.809C>T) in this patient and his mother.This mutation caused the amino acid change p. T270M (threonine>methionine). Many cases of MODY are misdiagnosed as either type 1 diabetes or type 2 diabetes.MODY11 is rare, mostly characterized by overweight or obesity, insufficient serum insulin secretion and commonly insulin dependence.

Objective:To evaluate the efficacy and safety of dexamethasone intravitreal implant (Ozurdex) in treating the refractory macular edema caused by retinal vein occlusion (RVO).Methods:An observational case series study was conducted.Twenty-one eyes of 21 patients diagnosed as refractory macular edema secondary to RVO and treated with Ozurdex implant in Beijing Aier-Intech Eye Hospital from March 2016 to September 2019, who was with a course lasting longer than 3 months and received at least 2 times of anti-VEGF treatments, had recurrent macular edema and no visual improvement or even deteriorated, were included.Best corrected visual acuity (BCVA) was examined using standard visual chart and was converted to logarithm of the minimal angle of resolution (LogMAR) units and intraocular pressure (IOP) was examined.Optical coherence tomography (OCT) was used to measure central retinal thickness (CRT) in all eyes before and at 1, 2, 3 and 6 months after intravitreal injection of Ozurdex.The changes of BCVA, IOP and CRT before and after Ozurdex injection were observed and analyzed.During the 6-month follow-up, re-injection of Ozurdex or ranibizumab was adopted among those with macular edema recurrence or poor efficacy according to the subjects' conditions.Ocular adverse effects and potential systemic complications were observed.This study followed the Declaration of Helsinki and the study protocol was approved by an Ecthics Committee of Beijing Aier-Intech Eye Hospital (No.BJAIER2020IRB01).Results:The mean CRT at 1, 2, 3, 6 months after Ozurdex injection was (295.76±49.19), (280.33±39.44), (321.29±73.46), (300.29±75.10)μm, respectively, which were significantly decreased in comparison with (458.52±174.61)μm at baseline (all at P<0.05). There was no significant difference in mean BCVA at different time points before and after Ozurdex injection ( F=1.975, P>0.05). During the follow-up, 10 eyes had macular edema recurrence at 2 to 6 months after first Ozurdex injection, with an average of (4.1±1.5) months.Among them, 8 eyes received second Ozurdex injection, and CRT was significantly reduced and BCVA was significantly improved at 6 months after the second Ozurdex injection in comparison with those at recurrence ( t=5.254, P=0.001; t=4.277, P=0.004). The IOP was significantly elevated at 2 months after first Ozurdex injection in comparison with that at baseline ( P=0.01). Ocular hypertension (IOP≥25 mmHg) was oberserved in 3 (14.3%) eyes during the follow-up period but were well controlled after local application of eye drops.No vitreous hemorrhage, retinal detachment, endophthalmitis or other serious adverse effects or systemic complications were observed. Conclusions:One dose of intravitreal Ozurdex injection can significantly improve the structure and function of macula in refractory macular edema caused by RVO for 4 to 6 months and maintain the baseline visual acuity.Second administration of Ozurdex is still effective for recurrent RVO macular edema.Transitional IOP elevation is the main adverse event.

OBJECTIVE: To discuss the pressure changing characteristics of upper esophageal sphincter (UES), lower esophageal sphincter (LES) and the esophagus kinetic characteristics of pharyngeal paraesthesia patients. METHOD: To take high resolution manometry in 44 cases of pharyngeal paraesthesia patients and 23 normal subjects separately. According to the RSI score,the 44 patients were divided into group A (the group without reflux, RSI < 13, n = 25) and group B (the group with reflux, RSI ≥ 13, n = 19). RESULT: The UES average resting pressure and average residual pressure of patients group were higher than the control group (P < 0.05); The UES average resting pressure and average residual pressure of group B were higher than group A (P < 0.05); The LES average resting pressure and average residual pressure of group B were lower than group A and the control group (P < 0.05); The comparison of LES average resting pressure and average residual pressure between group A and the control group was not statistically significant (P > 0.05). The esophagus DCI of group B was lower than that of group A and control group (P < 0.05). The esophagus DCI comparison between group A and control group was not statistically significant (P > 0.05). CONCLUSION The pharyngeal paresthesia symptoms of'patients was associated with the increasing of UES pressure. The pharyngeal paresthesia symptoms of group with reflux was related to low pressure of LES and high pressure of UES. The last part of esophagus of group with reflux had obstacles in powers, which weaken the peristalsis and declined the ability to clear the bolus and gastric reflux material.

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.

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 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.
