?Acute retinal necrosis syndrome ( ARN) is a serious eye disease, which caused by Herpes virus mostly, with unknown pathogenesis. Because of the aggressive progression, treatment of ARN is difficult, and the blindness rate is extremely high. Current treatment strategies are the combination of the drug therapy and the operative treatment. Drugs commonly used are antiviral drugs, glucocorticoids, and antiplatelet drugs, and the operative treatment includes laser photocoagulation and vitrectomy.

This paper aims to investigate the regulatory mechanism of blood-activating and stasis-dissipating drugs on fecal metabolic characteristics of rhubarb-peach kernel in mice with adenomyosis (AM) using fecal metabolome method. Adenomyosis was modeled by pituitary transplantation, and after the end of modeling administration, fecal samples were collected from mice. Non-targeted metabolomics studies were performed using liquid chromatography-mass spectrometry (LC-MS) to compare the metabolic characteristics of the feces of mice in each group and to find intestinal differential metabolites and potential differential metabolic pathways. The results showed that compared with the normal group, 5-hydroxy-L-tryptophan, histidine, L-acetylcarnitine, 16-hydroxy hexadecanoic acid, thromboxane B₂, etc. were significantly up-regulated, L-urobilin and prostaglandin D₃ were down-regulated in the feces of the model group, and were reversed after treatment with the rhubarb-peach kernel. The results of metabolic pathway enrichment analysis showed that tryptophan metabolism and histidine metabolism were the main intervention pathways of the rhubarb-peach kernel on AM intestinal metabolism. This study found that the underlying mechanism of the rhubarb-peach kernel in the treatment of AM is related to the intervention of intestinal metabolism of tryptophan, histidine, bile acid, choline and arachidonic acid, and the regulation of pro-inflammatory microenvironment and fatty acid metabolic homeostasis. This study has been approved by the Experimental Animal Ethics Committee of China Three Gorges University (No. 20190801).

Objective To investigate the features of digital subtraction angiography(DSA) of meningioma and the application of therapy in preoperative embolization.Methods DSA in 36 cases with meningioma proved pathologically was performed.Of them,22 cases which the blood supply of tumor was mostly by external carotid artery were undergone external carotid artery embolization and surgical incision 3~10 days after embolization.Results Among 36 cases,the blood supply of tumor was only from external carotid artery in 9 cases,both of external and internal carotid artery supply in 25,and only internal carotid artery in 2.Among 22 cases undergone embolization of supplying artery the tumor stain absolutely disappeared in 16,evidently decreased in 6.22 cases undergone surgical incision after embolization,the tumors were wholly resected,average bleeding 150~500 ml during surgery.Conclusion The blood supply of meningioma can be only by external or internal carotid artery,or both.Preoperative cerebral angiographies and embolization are beneficial for the total resection of meningioma and reduction of bleeding during surery.

Objective To explore the risk factors for intracranial hemorrhage caused by late vitamin K deficiency bleeding(VKDB),in order to prevent and reduce the incidence of intracranial hemorrhage caused by late VKDB.Methods A retrospective analysis of the risk factors of late VKDB and intracranial hemorrhage was applied to 2 groups of patients in PICU and department of neurology of Beijing children's Hospital from Jan.2002 to Dec.2007.In group Ⅰ,there were 90 patients suffering from intracranial hemorrhage caused by late VKDB;while in group Ⅱ,there were 23 patients of late VKDB without intracranial hemorrhage.Within 12 hours of hospitalization,the following 9 items were checked:the cranial CT,blood calcium concentration,liver function,serum sodium,blood glucose,prothrombin time,partial thromboplastin time,fibrinogen concentration,and platelet.Ten possible relevant risk factors of gender,age,birth situation,feeding patterns,recent diarrhea,cytomegalovirus(CMV)infection,hypocalcemia,dysglycemia,hyponatremia,and abnormal liver function were analyzed by the method of non-conditional Logistic regression analysis.Results Statistically significant difference had been found in the 3 factors of hypocalcaemia,recent diarrhea,abnormal liver function(Pa

Their specific chemical structure and biological activity have attracted a lot of attention in recent years. This article briefly reviews their biochemical characteristics, isolation, gene cloning, biological and neuropharmacological activities, as well as their potential applications.

Objective To observe the relationship between morphology of ciliary body and glaucoma with ultrasound biomicroscopy (UBM). Methods Eighty shallow-anterior chamber patients and 80 normal-anterior chamber patients were enrolled as shallow-anterior chamber group and control group, respectively. All patients were greater than 40 years old. The shallow-anterior chamber group included 28 patients of acute angle-closure glaucoma (AACG subgroup), 26 patients of chronic angle-closure glaucoma (CACG subgroup), and 26 patients of primary angle-closure suspects (PACS subgroup). Both eyes of all patients were checked with UBM, and position of each eye on sagittal and coronal section of superior, nasal, inferior and temporal were recorded. Then ciliary process height (CPH), ciliary process thickness (CPT), ciliary process interval (CPI), ciliary process number (CPN), A angle and α angle were measured. Furthermore, the difference between shallow-anterior chamber group and control group, the difference between AACG, CACG and PACS subgroup were compared, as well as the difference between PACS subgroup and control group, and the correlation between A angle and α angle was analyzed. Results Compared with control group, CPH and CPT of shallow-anterior chamber group increased, while CPI, CPN, A angle and α angle decreased (P＜0.05). Except CPH and CPN between CACG and PACS subgroup, there were significant differences of parameters between subgroup of AACG, CACG and PACS (P＜0.05). CPH of PACS subgroup increased than those of control group, while CPI, CPN, A angle and α angle decreased (P＜0.05). There was positive correlation between A angle and α angle. Conclusion Morphologic parameters of ciliary process may be sensitive indexes which can early screen primary angle-closure glaucoma.

Objective To study the expression of Stat5,E-cadherin and Vimentin in thyroid carcinoma and the correlation among them. Method The expression of Stat5,E-cadherin and Vimentin in 149 cases of thyroid specimens(including 23 cases of nodular goiter and 126 cases of thyroid carcinoma)was detected by immunohisto-chemistry SP method and the correlation analysis was conducted with the main clinical pathological parameters. Results The positive rate of Stat5 and Vimentin in thyroid carcinoma was 85.71% and 77.78% respectively, which was significantly higher than that in nodular goiter(26.09%and 8.70%)(P<0.05)and the positive rate of E-cadherin in thyroid carcinoma was 25.40%,lower than that in nodular goiter(86.96%)(P<0.05). Three kinds of protein expression were not significantly correlated with gender and age (P > 0.05),but obviously with lymph node metastasis and pathological type(P<0.05). Stat5 was negatively correlated with the expression of E-cadherin (r=-0.335,P=0.000)but positively with the expression of Vimentin(r=0.218,P<0.05). Conclusion The high expression of Stat5 and EMT in thyroid carcinoma tissues indicate that Stat5 may be involved in the EMT process of thyroid carcinoma ,thus it can promote the invasion and metastasis of thyroid carcinoma.

Objective To investigate the effects of glucagon like peptide 2(GLP 2) on the mRNA expressions of GLP 2 receptor (GLP 2R) and proglucagon gene(PG) in postburn rats. Methods A total of 55 Wistar rats were randomly divided into three groups including burn group, GLP 2 treatment group(treated with GLP 2, 200 ?g/kg, b.i.d ) and normal control group. Rats were sacrificed at 6, 12 h and 1, 3 and 5 d after burn injury. The proliferating cell nuclear antigen(PCNA) expression and the histological changes of the intestinal mucosa were determined by immunohistochemical staining. mRNA expressions of GLP 2R and PG were detected by RT PCR at 6, 12 h and 1, 3 and 5 d after burn injury. Results The expression of PCNA in rat intestinal mucosa decreased at 1 d after burn injury, but it was stronger in GLP 2 treatment group than that in burn group. Histological observation revealed that intestinal villi in GLP 2 treatment group were regularly arranged without obvious epithelial shedding. PG mRNA expression peaked at 12 h, 1 and 3 d after burn injury. No change of PG mRNA expression was found after treatment with GLP 2. Decreased GLP 2R mRNA expression was found in postburn rats, but after treatment with GLP 2, increased GLP 2R mRNA expression was found. Conclusion GLP 2 supplementation can keep the structure of the postburn rat intestinal mucosa without affecting PG gene expression. The mechanism may probably be related to the promotion of the mRNA expression of GLP 2R of the intestinal mucosa in rats.
