Background Researches showed that multifocal electroretinogram (mfERG) is able to assess the retinal function in the eyes with acute Vogt-Koyanagi-Harada ( VKH ) syndrome. But the mfERG characteristics of convalescence stage of VKH are still below clear. Objective Present study was to compare and follow up the variation process of visual acuity and mfERG in acute and recovery stages of VKH syndrome. Methods This was a clinic-based retrospective study. Visual acuity, mfERG and fundus fluorescence angiography ( FFA ) were recorded from 35 eyes of 18 acute VKH cases. The period of follow-up in recovery stage lasted about 18 months with the repetitive recording results for 4 times. Results In this study, the visual acuity range in acute stage VKH was 0. 01 to 1.0, and 91.4% (32/35 eyes) was below 0.6. Compared with normal control group, the visual acuity was significantly decreased (P＜0.01). The response densities (amplitudes) of N1 ,P1 waves of the first-order kernel were significantly lowed in all the 6 rings,and the implicit times of 1-4 rings of both waves were significantly prolonged in acute VKH eyes(P＜0. 05). The abnormalities of retinal function showed a regional difference at the posterior pole retina with the dominant change in the first ring,showing a cutting off78% in the P1 amplitude. The abnormal degree of mfERG was more serious as the the increase of retinal eccentricity. In 2 months of convalescence after glucocorticosteroids therapy,the range of visual acuity were 0. 1-1.2 ,and the amplitudes of N1, P1 of 1-2 rings were greatly elevated in comparison with acute on-set (P＜0. 05 ). However, there was still a remarkable difference in the amplitudes of from 1 through 6 rings,comparing with normal. The response density of P1 wave from whole recording region was only 44% of normal. Though the visual acuity was stable during the follow-up duration, a decreasing tendency in N1 and P1 amplitudes were seen. The implicit times of both wave shortened only in 1-3 rings in recovery stages of VKH (P＜0.05). Conclusion VKH syndrome cause serious damage of posterior retinal function.Macular region is the site with greater retinal functional lesion and restore before and after medication. This hardly recovery of retinal function can last over one and half year,even satisfied visual acuity is stable after proper treatment.

OBJECTIVETo compare clinical effects of spinal leveraging manipulation and medicine for the treatment of degenerative scoliosis in pain and function.

Objective To investigate the differences on lymphatic vessel density (LVD) among esophageal adenocarcinoma (EAC),esophageal squamous cell carcinoma (ESCC) and normal esophageal tissues,and analyze the clinical significance.Methods Twenty samples of EAC,24 samples of ESCC and 20 cases of normal esophageal tissues were obtained at the Affiliated Hospital of North Sichuan Medical College from January 2004 to January 2011.D2-40 was used for immunostaining of lymphatic vessels in EAC,and antibodies of D2-40 and Ki-67 were used together to detect proliferation of lymphatic vessels.The differences in the LVD among EAC,ESCC and normal esophageal tissues were analyzed.All data were analyzed using the analysis of variance or t test.Results D2-40 staining could identify the lymphatic vessels,and antibodies of D2-40 and Ki-67 could detect the proliferation of lymphatic vessels.The LVD of EAC,ESCC and normal esophageal tissues were (3.3 ± 1.7)/0.17 mm2,(4.6 ± 1.2)/0.17 mm2 and (3.8 ± 1.2)/0.17 mm2,respectively,with significant differences (F =5.44,P ＜0.05).The LVD of EAC was significantly lower than that of ESCC (t =3.074,P ＜ 0.05),while there was no significant difference in the LVD between the EAC and normal esophageal tissues (t =-1.022,P ＞ 0.05).There were significant differences in the LVD between the ESCC and normal esophageal tissues (t =2.395,P ＜ 0.05).There were significant differences in the LVD between EAC patients with deglutition discomfort and those with pain (t =3.092,P ＜ 0.05).There were significant differences in the LVD between EAC patients with course ＜6 months and those with course≥6 months (t =3.092,P ＜ 0.05).No statistical difference in clinicopathological parameters including gender,age,site of lesion,tumor diameter,pathological morphology,T stage,N stage,G stage,TNM clinical stage and lymph node metastasis were detected (t ＝ 1.130,1.020,F =0.082,t =0.799,F =0.692,t =0.694,1.820,0.353,0.969,0.969,P ＞ 0.05).Conclusions The LVD of EAC is lower than that of ESCC,but is similar to that of normal esophageal tissues.The LVD of EAC is correlated with the symptoms and course of patients.

OBJECTIVE To investigate the effect and mechanism of AngongNiuhuang Pill(AGNH) on neurological function and intestinal mucosal barrier in intracerebral hemorrhage (ICH). METHODS Male CD-1 mice were randomly divided into sham, ICH, AGNH 0.1 g·kg-1, AGNH 0.2 g·kg-1, and AGNH 0.4 g·kg-1groups. The ICH mice models were prepared by intrastriatal injection with collage-nase using a stereotaxic frame.Garcia test was used to evaluate the neurological function of mice.The brain water content was measured with dry/wet weight method.The permeability of intestinal mucosa was detected by FITC-D method. H&E staining was used to observe the pathological changes of intestine. The content of endotoxin in blood and the expressions of ZO-1,occludin in intestinewere also investigated.RESULTS After AGNH administration,the neurological score of mice was increased,and the brain water content was decreased(P<0.01).AGNH attenuated the ICH-induced increase of perme-ability of intestinal mucosa(P<0.01).Treatment with AGNHnot only alleviated the pathological changes of the intestine but alsoreduced the endotoxin content in blood (P<0.01).The expressions of ZO-1, occludinin AGNH groups were significantly increased compared with that of ICH group (P<0.05). CONCLUSION AGNH improves the neurological dysfunction in ICH mice and the mechanism of action is implicated in protecting the intestinal mucosa.

Objective To investigate the presence of occult brain tissue damage in patients with relapsing neuromyelitis optica(RNMO)and its possible mechanism by using diffusion tensor imaging (DTI).Methods DTI scans were performed in 16 patients with RNMO and 16 sex-and age-matched healthy controls.Histogram analysis of mean diffusivity (MD)and fractional anisotropy (FA)was performed in brain tissue (BT),white matter (WM)and gray matter (GM)to detect the presence of occult brain tissue damage in RNMO patients.Region of interest(ROI )analysis of MD and FA was also performed in 6 dedicated regions with or without direct connection with spinal cord or optic nerve to determine the relationship between occult brain tissue damage and the damage of spinal cord and optic nerve.Results Patients with RNMO had a significantly higher average MD of the BT[RNMO(0.95?0.02)? 10~(-3)mm~2/s,controls (0.91?0.03)?10~(-3)mm~2/s,t = 3.940,P

Objective To determine the relationship between abnormal blood glucose and lipid levels and body mass index in patients with chronic respiratory diseases. Methods This research was conducted in Urumqi baseline survey population from "Xinjiang multi-ethnic cohort study" in which patients with chronic bronchitis, emphysema and chronic obstructive pulmonary disease (COPD) were screened.The patients were defined as angular, normal, overweight, obesity groups according to body mass index (BMI), and were compared with blood levels of lipid and glucose, and rate of abnormal metabolism. Results A total of 6 046 subjects were included in the 2018 Urumqi cohort study, including 545 patients with chronic respiratory diseases.The prevalence of chronic respiratory diseases in different age groups and at different physical activity levels was different, and the prevalence of emaciation group was significantly higher than that of the other three groups.However, there were no statistically significant differences among people with different genders, nationalities, educational levels and whether they smoked or not.There were statistically significant differences in fasting glucose, serum cholesterol (TC) and serum high-density lipoprotein (HDL) levels among respiratory patients with different BMI (P < 0.05).The detection rates of hyperglycemia, high TG and low HDL increased with the increase of BMI.The result of multi-factor analysis showed that blood glucose, TG and HDL were the influencing factors of BMI. Conclusion Increase of body mass index in patients with chronic respiratory diseases is associated with abnormal glucose and lipid metabolism, which is not significantly different from that in patients with non-respiratory diseases.However, the body mass index and nutritional status of patients with long-term diseases should be closely monitored, and timely intervention measures should be taken to delay the disease process.

OBJECTIVETo summarize clinical outcomes of locking compression plate (LCP) combined with minimally invasive percutaneous plate osteosynthesis (MIPPO) for the treatment of Pilon fracture.

METHODSFrom January 2009 to December 2012, Pilon fracture patients treated by LCP with MIPPO were retrospectively analyzed. All open fractures, pathologic fractures and those who had limb vascular disease or nerve injury were excluded. Thirty-eight patients were enrolled, including 29 males and 9 females aged from 21 to 78 years old with an average of 48 years old. According to AO classification, 20 cases were type B, 18 cases were type C. Operative time, blood loss, reduction quality, time of fracture healing complications and postoperative ankle joint function were applied for evaluating clinical outcomes, AOFAS scoring were used for assessing postoperative clinical effects.

RESULTSAll patients were followed up from 13 to 24 months (averaged 18 months). All patients obtained bone union without any plate failures or loss of fixation/reduction. One patient occurred superficial wound infection, and resolved with antibiotics and local wound care. Postoperative average AOFAS score was 81 (ranged 65 to 97).

CONCLUSIONLCP with MIPPO for Pilon fratcure has advantages of less invasion, fewer complications and satisfactory ankle function.
