We predicted the anti-ulcerative colitis (UC) mechanism of Fructus Amomi based on network pharmacology. The anti-UC activity of Fructus Amomi were investigated by in vivo animal experiment, and the active components of Fructus Amomi were obtained through TCMSP, PubChem database and literature research. Animal welfare and experimental procedures follow the regulations of the Animal Ethics Committee of Institute of Materia Medica of Chinese Academy of Medical Sciences. The potential targets of the active components and UC were predicted by SwissTargetPrediction, GeneCards and TTD databases. The protein-protein interaction (PPI) network was constructed by String database and Cytoscape software was used to construct a visual network of active component-disease target and perform topological analysis. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses were performed using Metascape platform. The molecular docking of key components and core targets was carried out by Sybyl X software. We screened out a total of 12 active components and 189 disease-component overlapping targets. Enrichment analyses obtained 227 related GO items and 168 signaling pathways. According to the results of molecular docking, most active components of Fructus Amomi showed good affinity with the JAKs receptor family. Furthermore, Western blot results verified that Fructus Amomi could effectively inhibit JAK/STAT signaling pathway, indicating that Fructus Amomi might exert the anti-UC activity by regulating JAK/STAT signaling pathway.

OBJECTIVETo observe the effect of Shen warming Pi strengthening method on expressions of serum T cell subsets (C045+%, C03+%, and C04 +/COB+) in diarrhea-predominant irritable bowel syndrome (IBS-0) rats. Methods An IBS-0 rat model was established referring to AL-Chaer's modeling method combined with tail clamp and intragastric administration of sanna leaf. After modeling 30 SO rats were randomly divided into 6 groups according to random digit table, i.e., the model group, the high, middle, low dose Wenshen Jianpi Recipe (WJR) groups, and the Sishen Pill control group, 6 in each group. A normal control group consisting of 6 SO rats were also set up. Rats in high, middle, low dose WJ R groups were administered by gastrogavage with boil-free WJ R at the daily dose of 3. 100, 1. 550, 0. 775 g/kg, respectively. Rats in the Sis hen Pill control group were administered by gastrogavage with boil-free Sis hen Pill at the daily dose of 0. 736 g/kg. Equal volume of normal saline was given by gastrogavage to rats in the model group and the normal control group. All medication lasted for 2 successive weeks. Rats' general state, expressions of T cell subsets (CD45+%, CD3+%, and CD4+ /CDB+) changes were observed.

RESULTSCompared with the normal control group, expressions of CD45+% and CD3+% increased, but CD4+ /CDB+ decreased with statistical difference (P < 0. 05). Compared with the model group, expressions of CD45+% and CD3+% decreased, but CD4+ ICDB+ increased with statistical difference in high, middle, low dose WJR groups, and the Sis hen Pill control group (P <0. 05). Compared with the Sis hen Pill control group, there was statistical difference in all indices except CD45+ value in the low dose SWPSM group (P <0. 05). Compared with the low dose WJ R group, the expression of CD3+% decreased in high and middle dose WJR groups, and the Sis hen Pill control group; CD4+ /CD8+ increased in the Sishen Pill control group and the high dose SWPSM group (all P < 0. 05).

CONCLUSIONSWJR showed better treatment effect. The mechanism of Shen warming Pi strengthening method might be achieved by regulating expressions of CD45+% and CD3+%, and CD4+ /CD8+ ratios.

Objective To discuss the distribution laws of TCM syndromes of early threatened abortion; To analyze the related factors of pregnancy outcome of early threatened abortion. Methods The study included 1010 hospital patients who were diagnosed as early threatened abortion. Excel2010 was used to establish database in order to collect general information such as the age, menstrual history, times of abortion and adverse pregnancy, incidence of solar term and pregnancy week, the type of TCM syndromes and the pregnancy outcome (at least 3 months after being out of hospital) of patients. The distribution laws of TCM syndromes, and related factors of pregnancy outcome were analyzed. Results Among the 1010 cases, 762 cases were with kidney deficiency syndrome (75.4%); followed by blood heat syndrome, a total of 178 cases, accounting for 17.6%; qi and blood deficiency syndrome, a total of 40 cases, accounting for 4%; blood stasis syndrome, a total of 15 cases, accounting for 1.5%; liver stagnation syndrome, a total of 15 cases, accounting for 1.5%. The distribution of TCM syndromes was statistical significance in the different age groups and the incidence of pregnancy week (P<0.01). But there was no statistical significance in menstrual history, times of abortion, times of adverse pregnancy, and the incidence of solar term (P>0.05). Among the 1010 cases, follow-up to 698 cases, 567 cases were successful pregnancies, accounting for 81.2% of the follow-up of patients; 131 cases were failed pregnancies, accounting for 18.8% of the follow-up of patients. In the study, it found that there was statistical significance between different age groups and pregnancy outcomes (P=0.026). The pregnancy outcomes were related to the age groups (P=0.012, OR=1.063), and it was not related to TCM syndromes, times of abortion, times of adverse pregnancy, menstruation, pregnancy week. Conclusion Kidney deficiency syndrome is the main syndrome of early threatened abortion. The distribution of TCM syndromes is related to the age group and the incidence of pregnancy week of patients. Age of patients is the related factor affecting the pregnancy outcome.

AlM:To analyze and compare the effect of femtosecond laser micro - incision corneal stromal lens excision ( SMlLE) and excimer laser in situ keratomileusis ( LASlK) in the treatment of myopia after operation, to explore the safety, operability and prediction of SMlLE.METHODS:ln this prospective clinical controlled study, 100 cases ( 200 eyes ) received SMlLE and 100 cases ( 200 eyes) undergone LASl in our hospital in the same period were selected. Uncorrected visual acuity, diopter, corrected visual acuity, slit lamp examination, intraocular pressure and corneal anterior segment OCT, corneal topography (Obscan ll) of two groups in 1d, 1wk, 1, 3, 6mo, 1a were compared. lndependent samples t test was used for data analysis.RESULTS:1) Postoperative slit lamp examination:after 1d in SMlLE group, there were less eyes had corneal layer between mild cloudy or edema; postoperative 1wk corneal layer disappeared, cornea became clear and transparent. 2 ) Postoperative vision recovery: 1d after operation, vision recovery in LASlK group was better than that in SMlLE group, the difference was statistically significant (P<0. 01), there were no significant differences at 1wk, 1, 3, 6mo, 1a after operation ( P>0. 05 ). 3 ) Obscan ll examination: graphics in the SMlLE group was more regular and placed in the center, no eccentric and irregular graphics, better than that in the LASlK group. 4) Anterior segment OCT examination:postoperative corneal flap in the SMlLE group was more uniform and accurate, but it was thin in the center and slightly thick the peripheral part in the LASlK groups. 5 ) Postoperative visual quality assessment used subjective questionnaire survey. The two groups had statistically significant difference on 4 points and 1 points (P<0. 05). Complains in the LASlK groups were more that that in the SMlLE group. While, no complain of the SMlLE group was higher than that of the LASlK group. Glare of postoperative patients with night vision and dark environment in the SMlLE group was better than that of the LASlK group.CONCLUSlON: SMlLE is safe, effective, stable and predictable for the correction of myopia.

Objective:To determine the derivative chromosome 9 by the method of detecting the ASS gene,and to explore the relationship between the deletion of derivative chromosome 9 and the efficacy and prognosis of the chronic myeloid leukemia (CML)patients. Methods:The materials of 34 CML patients with positive BCR-ABL fusion gene whose ASS genes were detected were retrospectively analyzed. All patients were treated with Extra-signal (ES)probe to detect the derivative chromosome 9.All patients were divided into two groups according to whether they carried the derivative chromosome 9.The blastic phase or the accelerated phase rates in two groups were compared by using Fisher exact probability. Results:All patients were detected by FISH (BCR-ABL ES probe),and all the BCR-ABL fusion signals were positive.6 of 34 patients were found the deletion of ASS gene, among them 1 case blonged to chronic phase,and 5 cases developed into blastic phase or accelerated phase. In the patients without ASS gene deletion,there were 22 cases in chronic phase,and 6 cases in plastic phase or accelerate phase,there was significant difference of blastic phase rate/accelated phase rate between them (P<0.05).A total of 26 patients were treated with tyrosine kinase inhibitors (TKI).5 of 26 patients belonged to the ASS gene deletion group,1 of 5 patients treated with TKI got molecular remission,4 of 5 patients developed into blastic phase or accelerated phase.21 of 26 patients belonged to the group without ASS gene deletion,and among them,19 cases got molecular remission,2 cases developed into plastic phase or accelerated phase after treatment of TKI,there was significant difference between them (P < 0.05 ). 6 patients were treated with traditional chemotherapy (hydroxyurea,interferon);1 of 6 patients belonged to the ASS gene deletion group,finally developed into the blastic phase or accelerated phase;5 of 6 patients belonged to the group without ASS gene deletion,2 cases got the hematological remission,and 3 patients developed into blastic phase or accelerated phase after treatment,and there was no significant difference of blastic phase rate/ accelerated phase rate between them (P > 0.05 ). Conclusion:The CML patients with derivative chromosome 9 (ASS gene deletion)prone to get disease progression, and have a higher proportion in the blastic phase or accelerated phase patients.Derivative chromosome 9 is related to the bad treatment efficacy of TKI and the poor prognosis of CML.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.

OBJECTIVETo study the selective dilatation effects of iptakalim (Ipt) on basilar and pulmonary arterioles, and endothelial cell function of these arterioles in hypoxic rats.

METHODSSD male rats were divided into 2 groups:control and hypoxic group fed in normobaric hypoxic environment (O2 7.8%, 8 h). Arteriole rings about (204 + 5) pm were isolated and the tension of hypoxic arterioles pre-contracted by 6 nmol/L endothelin-1 (ET-1) was observed with wire myograph system model (DMT 610 m). The relaxing response of hypoxic arterioles induced by different concentration of Ipt were detected and endothelial activity was also tested by acetylcholine.

RESULTS10(5) mol/L acetylcholine (ACh)-mediated vasodilatation of basilar and pulmonary arterioles was greatly reduced in the hypoxic group than those in control group (P < 0.05). Compared with normal group, a novel ATP-sensitive potassium channel opener Ipt at the concentration ranging from 10(-11) mol/L to 10(3) mol/L, caused stronger dose dependent vasodilatation on hypoxic pulmonary arterioles, and there was no significant difference between control and hypoxic basilar arterioles.

CONCLUSIONThe endothelial function of basilar and pulmonary arterioles was damaged under hypoxic state, and Ipt selectively increased dilatation effects on hypoxic pulmonary arterioles, but not on hypoxic basilar arterioles which could improve high altitude pulmonary edema pathological state and be the novel drug in the treatment of pulmonary hypertension.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).

METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.

RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).

CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.
