Objective To investigate the effects of magnesium isoglycyrrhizinate on liver regeneration and hepatic function following partial hepatectomy in thioacetamide induced cirrhotic rats.MethodsForty-five cirrhotic Wistar rats undergoing 2/3 hepatectomy were randomly assigned to control group ( Group A), Group B and Group C starting the day of hepatectomy, rats in Group B were injected 60mg per kg body-weight magnesium isoglycyrrhizina daily intraperitoneally until the day of sacrifice. Rats in Group A recevied same dose of sodium chloride. In Group C, magnesium isoglycyrrhizina was administered daily 3 days before hepatectomy until the rats were sacrificed. Liver function, serum HGF, serum PLA2,BrdU labelling index and percentage of intial liver weight on days 1, 2 and 7 post hepatectomy were assessed. ResultsRats in Group A had significantly lower BrdU labelling index and serum HGF level than Group C ( t = 2. 831, P ＜ 0.05; t = 3.427, P ＜ 0.05 ) and a markedly higher level of serum PLA2 than the other groups on day 1 posthepatectomy ( Group B t = 2. 794, P ＜ 0.05; Group C t = 2. 902, P ＜ 0.05 ).Rats in Group A had a lower BrdU labelling index and a more increased level of serum PLA2 than Group B and Group C on day 2 posthepatectomy ( BrdU labelling index: Group B t = 2. 736, P ＜ 0.05; Group C t =3.083, P＜0.05; PLA2: Group B t =2.794, P＜0.05; Group C t =2.902, P＜0.05), but had no significant difference in HGF level with the other two groups. The three groups were similar in ALT, AST,TP and intial liver weight on days 1,2 after operation. On the 7th day posthepatectomy, rats in Group A had a higher level of AST ( Group B t = 4. 508, P ＜ 0.05; Group C t = 2. 967, P ＜ 0.05 ) and a lower level of TP ( Group B t = 2. 838, P ＜ 0.05; Group C t = 2. 743, P ＜ 0.05 ), lower liver weight than the other two groups ( Group B t = 3.316, P ＜ 0.05; Group C t = 4. 093, P ＜ 0.05) but there was no difference between the three groups in BrdU labelling index, HGF and PLA2 level. Rats in Group C had significantly higher BrdU labelling index and serum HGF level than the rats in Group B on day 1 after hepatectomy( t = 2. 831, P ＜0.05; t = 2. 836, P ＜ 0.05 ).ConclusionsMagnesium isoglycyrrhizinate inhibits aminopherase release and enhancing liver regeneration in cirrhotic rats after partial hepatectomy.

Objective To investigate the value of global longitudinal strain (GLS) in detecting severe coronary artery stenosis (SCAS) in patients with coronary artery disease. Methods Fourty-two patients with SCAS confirmed with coronary arteriongraphy (CAG) underwent two-dimensional strain echocardiography. GLS, wall motion score index (WMSI) and left ventricular ejection fraction (LVEF) were obtained. Taking CAG as gold standard, the sensitivity, specificity and areas under the ROC curve (AUC) of definition of SCAS with GLS, WMSI and LVEF were calculated, respectively. Fifteen healthy volunteers were recruited as control. Results ①Definition of one or more branches with severe stenosis: The sensitivity and specificity was 77.51% and 100% with GLS of -17.50% as a cutoff value, 70.01% and 100% with WMSI of 1.00, and 57.51% and 100% with LVEF of 59.21%. ②Definition of two or more than two branches with severe stenosis: The sensitivity and specificity was 62.52% and 80.81% with GLS of -11.05% as a cutoff value, 56.22% and 65.31% with WMSI of 1.60 and 56.21% and 65.42% with LVEF of 54.31%. ③The correlation coefficient was 0.78 between GLS and LVEF, and -0.82 between WMSI and LVEF. The AUC of detecting one or more branch with severe stenosis with GLS, WMIS and LVEF was 0.87, 0.80 and 0.78, respectively, and AUC of GLS was more than that of LVEF (P＜0.01). AUC of detecting two or more than two branches with severe stenosis with GLS, WMIS and LVEF was 0.76, 0.64 and 0.64, AUC of GLS was more than that of LVEF and WMSI (all P＜0.01). Conclusion GLS can be used in detecting SCAS, and the value of GLS is better than that of WMIS and LVEF.

Observation revealed the abnormalities (increased CD 4 and Th, decreased Tc) in patients of Graves′ disease, and these abnormalities were not significantly adjusted after 6 weeks of treatment with methimazole (MMI), or with MMI and methotrexate (MTX), though the soluble interleukin-2 receptor and thyroid autoantibodies slightly decreased in both groups. However, the addition of MTX did not show any better effects than MMI alone in the treatment.

Objective To evaluate right ventricular (RV)systolic function in type-2 diabetes mellitus (T2DM)patients.Methods Fifty T2DM patients and fifty normal controls were included in the study and underwent echocardiographic examinations.The following parameters were measured:1 ) Right heart dimensions,pulmonary artery (PA)diameter,pulmonary acceleration time (AT)and PA systolic pressure (PASP);2)RV systolic function:RV fractional area change (RVFAC),tissue Doppler-derived tricuspid lateral annular systolic velocity (S'),tricuspid annular plane systolic excursion (TAPSE),longitudinal strain of six RV segments by 2-dimensional speckle tracking imaging (2D-STI);3 )RV diastolic function:E,A ratio of the tricuspid inflow spectrum (E/A),E,E'(peak early diastolic velocity of the tricuspid annulus) ratio (E/E');4)RV Tei index.Results Statistic analysis showed that T2DM patients had thicker RV walls,wider PAs and shorter AT than the control group (P =0.000,0.001 and 0.000),while their right heart chamber sizes and PASP remained unchanged.Among systolic parameters,absolute values of RV longitudinal strain at the lateral wall-mid (lat-m),septum-mid (sep-m)and septum-basal (sep-b)segments were significantly lower in the diabetic group than the control group (P =0.001 ,0.000 and 0.005),whereas strain of the other three RV segments and RVFAC,TAPSE.S'were not significantly different.Moreover, E/A,E/E'and Tei index were all significantly different between the two groups (P = 0.000,0.000 and 0.006),indicating declined diastolic and general function of RV in the T2DM group.Conclusions RV myocardial strain by 2D-STI is more sensitive in detecting RV systolic dysfunction than TAPSE,S' and RVFAC.Among the six segments of RV walls,lat-m,sep-m and sep-b are better locations for 2D-STI than the other three.

The possibility that a recombinant protein vaccine based on xenogeneic homologous FGFR-1 of chicken induces production of autoantibodies against self-FGFR-1 in BALB/c mice was examined by using ELISA, Western blot analysis and ELISPOT assay respectively. Autoantibodies against mouse FGFR-1 were identified by Western blot analysis and ELISA. Compared with the two control groups, the number of APBCs, which were detected by ELISPOT assay, was significantly increased in the spleens of mice immunized with cFR1 (P < 0.05). IgG1 and IgG2b, which were detected by ELISA, were the major subclasses and were substantially increased in response to chicken FGFR-1 when compared with control group. The recombinant chicken FGFR-1 protein used as a vaccine can induce autoantibodies against self-FGFR-1 in mice and provide a basis for the active immunotherapy of tumor angiogenesis.

Objective To observe and analyze the application of ultrasonography to clinical treatment and diagnosis of patients with hemodialysis before and after artificial arteriovenous fistula. Methods A total of 72 cases with uremia hemodialysis treated in our hospital received ultrasonography before and after artificial arteriovenous fistula. The suit-able blood vessels were selected, and the functions of artificial arteriovenous fistula were evaluated and analyzed. Re-sults The ultrasound indicated that the success rate of fistulization with low blood flow was 25.00%, and that with nor-mal blood flow was 55.56%, and that with high blood flow was 19.44%. The success rate of the normal group was evi-dently higher than that of the high or low blood-flow group. The blood flow and blood velocity of patients 1 week, 2 weeks and 4 weeks after operation increased steadily. Conclusion Applying ultrasonography to diagnose and monitor the patients with hemodialysis of artificial arteriovenous fistula can improve the diagnostic level and treatment level for the disease, which can be promoted and applied in clinical practice.

Objective To assess the value of transesophageal echocardiography (TEE) in left atrial appendage (LAA) closer with Amplatzer Cardiac Plug (ACP).Methods Consecutive 32 atrial fibrillation patients (CHADS2≥1) with high risk bleeding underwent LAA occlusion with ACP LAA occlusion device under the guidance of TEE.Measurements of LAA anchoring area diameter (AAD) and LAA anatomical orifice diameter (AOD) including maximum,minimum values,and LAA depth on 2 dimentional TEE (2D TEE) were conducted before closer device implantation.The outcomes of LAA occlusion were analyzed.Results Among 32 patients,27 cases achieved successful LAA occlusion,including 2 cases with peripheral leakage ≤5 mm,and 5 cases failed occlusion.Among 5 failed closed patients,3 cases with LAA AAD≥ 30 mm,1 case with LAA of short depth,and 1 case with anatomical variation of LAA of low position that access sheath could not be positioned in the LAA.LAA AAD maximum,minimum and LAA depth were (25.9±4.9)mm,(20.0±3.8)mm,(31.0±5.6)mm,respectively,and LAA AOD maximum,minimum diameters were (26.2±6.2)mm,(19.4±4.3)mm,respectively.Among 10 cases with LAA AAD≥30 mm,7 cases achieved successful LAA occlusion,but 3 cases failed.The implanted device diameter was (26.4±3.8)mm,and device compression rate was (7.6±5.5)%.The coefficient of correlation between device diameter and large LAA AAD and AOD is 0.770 and 0.717,respectively.There was no complication but 1 case with pericardial effusion.Conclusions Two dimentional TEE measurements of LAA have clinical guiding significance in the selection of proper size of ACP LAA occluder.The AAD of 2D TEE has the good correlation with ACP occluder′s size,the AADs are important factors which affect the success of LAA occlusion.

OBJECTIVE: To investigate the inhibitory effect of gonadotropin-releasing hormone II(GnRHII) and gonadotropin-releasing hormone I agonist (GnRH Ia) on the proliferation of endometrial stromal cells in vitro from endometriosis patients. METHODS: Different concentrations of GnRHII or GnRH Ia were added into the cultured endometrial stromal cells in vitro to detect the cell proliferation inhibition by MTT test. RESULTS: The inhibitory rate of GnRHII or GnRH Ia on eutopic and ectopic endometrial stromal cells in vitro was both dose- and time-dependent (P<0.05). Effect of GnRHII or GnRH Ia on the inhibitory rate of ectopic endometrial stromal cells was significantly higher than that of eutopic (P<0.05). GnRH II had a higher inhibitory rate on the endometrial stromal cells in vitro than did GnRH Ia (P<0.05). CONCLUSION GnRHII has more antiproliferative effect on endometrial stromal cells than GnRH Ia in vitro, especially on ectopic endometrial stromal cells, suggesting that GnRHII may be more effective than GnRH Ia on endometriosis.

Objective:To investigate the risk factors for the occurrence and poor in-hospital prognosis in patients with peripartum cardiomyopathy (PPCM).Methods:The clinical data of 35 patients with PPCM and 35 healthy pregnant women in Xuanwu Hospital, Capital Medical University and Beijing Friendship Hospital Affiliated to Capital Medical University from January 2003 to January 2022 were retrospectively analyzed. The personal histories, laboratory examination, imaging examination, cardiac function outcome, etc were collected. According to the left ventricular ejection fraction (LVEF) at discharge, the patients with PPCM were divided into in-hospital recovery group (LVEF≥50%, 18 cases) and prolonged disease group (LVEF<50%, 17 cases). Multivariate Logistic regression analysis was used to analyze independent risk factors of poor in-hospital prognosis in patients with PPCM.Results:Among 35 patients with PPCM, the age was (29.81 ± 5.37) years old, 17 cases (48.57%) complicated with gestational hypertension, 6 cases (17.14%) complicated with gestational diabetes mellitus, 24 cases (68.57%) of New York Heart Association (NYHA) cardiac function classification was Ⅲ to Ⅳ class, and 4 cases died (11.43%). The gestational age in patients with PPCM was significantly shorter than that in healthy pregnant women: (36.26 ± 4.27) weeks vs. (38.54 ± 4.59) weeks, the rates of multiple pregnancy and gestational hypertension were significantly higher than those in healthy pregnant women: 17.14% (6/35) vs. 2.86% (1/35) and 48.57% (17/35) vs. 11.43% (4/35), and there were statistical differences ( P<0.05 or <0.01). Compared with hospital recovery group, the patients in protracted disease group had shorter gestational age, larger left ventricular end-diastolic diameter, higher serum creatinine, C-reactive protein and amino-terminal pro-brain natriuretic peptide (NT-proBNP), worse NYHA cardiac function classification, and there were statistical differences ( P<0.05 or <0.01); but there were no statistical difference in LVEF at the first diagnosis and troponin I between two groups ( P>0.05). Multivariate Logistic regression analysis result showed that elevated creatinine was an independent risk factor for poor in-hospital prognosis in patients with PPCM ( OR = 4.554, 95% CI 1.536 to 13.684, P = 0.018). Conclusions:The gestational hypertension may be a risk factor for PPCM. The gestational hypertension, earlier onset time, enlarged left ventricular end-diastolic diameter, high NT-proBNP, high C-reactive protein, high creatinine and high cardiac function NYHA classification may be risk factors for poor in-hospital prognosis in patients with PPCM; and elevated creatinine is an independent risk factor for poor in-hospital prognosis in patients with PPCM.
