Objective To investigate the effects of exogenous biliverdin on lung injury induced by brain death (BD) in rats. Methods Twenty-three adult male Wistar rats in which Fogarty balloon catheter was successfully inserted into cranial cavity were randomly divided into 3 groups: group Ⅰ sham operation (group S,n = 7); group Ⅱ brain death (group BD, n = 8) and group Ⅲ biliverdin + BD (group B, n = 8). The animals were anesthetized, intubated and mechanically ventilated. Femoral artery and vein were cannulated for MAP monitoring and drug and fluid administration. Brain death was induced by injecting slowly normal saline into the balloon in group Ⅱ and Ⅲ. BD was confirmed by dilated and fixed pupils, apnea, transient hypertension and EEG changes. In group Ⅲ biliverdin 35 mg/kg was injected intraperitoneally as soon as BD was confirmed. The animals were mechanically ventilated for another 1.5 h during which MAP was maintained at 80-120 mm Hg by iv norepinephrine infusion. Arterial blood samples were obtained before anesthesia, immediately before and at 5, 30,60, 90 min after intraperitoneal biliverdin for blood gas analysis and determination of plasma bilirubin concentration. PaO2/FiO2 was calculated. The animals were sacrificed at 1.5 h after biliverdin administration. The left lung was removed for detection of MDA content, SOD activity, total antioxidant capacity, cell apoptosis and biliverdin reductase expression in lung tissue. Results Brain death significantly decreased PaO2/FiO2, lung SOD activity and total antioxidant capacity and increased lung MDA content and apoptosis as compared with sham operation group. IP biliverdin significantly attenuated BD-induced lung injury in group B as compared with group BD. The plasma bilirubin concentration and biliverdin reductase expression were significantly higher in group B than group BD. Conclusion Exogenous biliverdin can attenuate BD-induced lung injury by inhibiting pulmonary oxidative stress response and apoptosis.

Objective To analyse the clinical efficacy of methotrexate (MTX) combined with intrauterine embryo sac garrotte injection in the treatment of cesarean scar pregnancy (CSP), and discuss its clinical significance. Methods A total of 77 patients with CSP treated in our hospital during June 2013 to December 2016 were selected in this study. Forty patients treated with embryo sac destruction and methotrexate injection were included in the observation group, while 37 cases treated by uterine artery embolization combined with curettage were used as the control group. The time of vaginal bleeding, the time of postoperative blood level of human chorionic gonadotropin (HCG) returned to the normal level, average hospitalization cost and the curative rate were recorded in two groups. All patients were followed up by the outpatient visit. Results In the observation group, the vaginal bleeding time [(22.1±6.7) days vs. (29.5±10.8) days] and treatment cost [(8774.2 ± 714.5) yuan vs. (15258.3 ± 1084.2) yuan] were less than those of the control group (P<0.001). There were no significant differences in the recovery time of HCG [(26.4±9.0) days vs. (25.1±10.4) days] and treatment success rate (87.5%vs. 91.9%) between the two groups (P>0.05). No bleeding or threatened rupture of scar were found in two groups of patients. Conclusion In this study, we take the embryo sac puncture combined with methotrexate injection in the treatment of scar pregnancy. This method has the advantages of low operative difficulty, definite clinical curative effect and low cost

This study aims to perform a survey of genetic variation in neuraminidase (NA) gene of influenza A/H3N2 virus, as well as related resistance to NA inhibitors, in Qinghai Province of China, 2010 to 2012. Strains of influenza A/H3N2 isolated during an influenza survey from 2010 to 2012 in Qinghai were enrolled by random sampling. Viral RNA was extracted and amplified by RT-PCR. Purified PCR products were sequenced thereafter. Genetic analysis of nucleic acid and the derived amino acid sequences was performed by MEGA 4.0. Phylogenetic trees were also constructed. Strains isolated during 2010-2011 in this study clustered closely with World Health Organization (WHO) 2010-2012 reference vaccine strain A/Perth/16/2009 and 2008-2010 reference vaccine strain A/Brisbane/10/2007 on the phylogenetic tree, while the 2012 isolates were located on another branch. In analysis of derived amino acid sequences, the 2010 isolates mutated at K81T, the 2011 isolates mutated at I26V and D127N, while the 2012 isolates mutated at E41K, P46A, I58V, T71N, L81P, D93G, D127N, D151N, and I307M. The D151N mutation added a glycosylation site to the activity center of NA. No significant variation was discovered in H3N2 NA gene of 2010-2011 isolates in Qinghai, China. Isolates of 2012 were found with significant mutation, which has the potential of inducing minor resistance to NA inhibitors like zanamivir and oseltamivir.

Objective To analyze the differences of biochemical and immunological indicators in gender or Lee′s classification of IgA nephropathy ( IgAN) to provide laboratory evidence for clinical diagnosis and treatment of IgAN.Methods Retrospective cohort study.The information of biochemical and immunological indicators of 213 in-hospital patients which were admitted in Chinese PLA General Hospital in June to December, 2012.The data were collected and analyzed with t-test, non-parameter analysis, Pearson correlation analysis, ROC curves analysis and Logistic regression analysis according to gender or Lee′s classification ( Lee′s≤3 group and Lee′s>3 group).Results In this study, the average age and sex ratio of patients with IgAN was ( 35.0 ±10.6 ) years old and 2.04∶1.00.T-test and non-parameter analysis indicated homocysteine(HCY), immunoglobulin E (IgE), immunoglobulin M (IgM), prealbumin (PA), ceruloplasmin ( CP) ,α1-acidoglycoprotein(α1-AGP) , albumin ( Alb) ,α2-globulin(α2-G) andγ-globulin (γ-G) had significant difference in gender (P<0.05).And cystantin-C (CYS-C), HCY, complement 4 (C4),β2-microglobulin(β2-MG), PA, α1-AGP, α1-globulin(α1-G), immunoglobulin G (IgG), IgM and transferrin ( TF ) had significantly different in Lee′s classification ( P<0.05 ).ROC curves analysis showed that the areas under curves of CYS-C andβ2-MG were 0.891 and 0.839 respectively;the sensitivity was 90.2%and specificity was 75.3% when cutoff value of CYS-C was 1.56 mg/L; the sensitivity was 80.3%and specificity was 78.8% when cutoff value of β2-MG was 0.275 mg/dl.Logistic regression analysis showed that CYS-C ( OR: 31.380, 95% CI: 10.808 -91.113, P=0.000 ) and HCY ( OR:1.035, 95%CI:1.002-1.069, P=0.040) were introduced into the model after twice variable selections.ROC curve of CYS-C combined with HCY for classifying Lee′s classification showed that the sensitivity, specificity, Jorden index and AUC were 0.843, 0.862, 0.705 and 0.894 ( P=0.000 ) , respectively.Conclusions CYS-C,β2-MG, PA and HCY were valuable indicators for Lee′s classification.CYS-C andβ2-MG had high correlation with Lee′s classification, which indicated that these two tests were related to the severity of IgAN.CYS-C combined with HCY could improve the diagnostic efficiency of IgAN Lee′s classification.Combination of biochemical and immunological indicators could improve the accuracy of Lee′s classification and provide effective laboratory evidence for clinical treatment of IgAN.

Objective: To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA. Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system. Results:The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (allP<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05). Conclusion: Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.

Objective To study the effects of postnatal overfeeding and high-fat diet on blood pressure of rats,and to explore the pathophysiological mechanism underlying hypertension induced by continuous early postnatal overfeeding.Methods Male Sprague-Dawley rats were randomly divided into normal feeding group (10/litter) and overfeeding group (3/litter) on postnatal day 3 with a random number table.After weaning at postnatal week 3,the rats were randomly given standard chow or high-fat (HF) diet until week 16.Hence four groups were analyzed,namely normal feeding group,breastfed overfeeding group,post-weaning overfeeding group,and continuous overfeeding group.Body weight was continuously monitored in each week.Visceral fat pad (retroperitoneal and perigenital),systolic pressure,and heart rate were observed at week 3 and week 16.Thoracic aorta was sampled for measurement of vascular endothelial dilation function.Histological morphology was observed with HE staining,nitric oxide content of thoracic aorta was detected with nitrate reductase method.The mRNA expression of endothelial nitric oxide synthase (eNOS) in thoracic aorta was determined by real-time polymerase chain reaction.The protein expressions of eNOS and phosphorylated eNOS were determined by Western blot.Results At week 3,breastfed overfeeding rats displayed significantly larger body weight [(77.80 ± 0.57) g vs.(62.80 ±0.85) g,t =14.576,P ＜ 0.01] and visceral fat [retroperitoneal:(8.19 ± 0.49) mg/g vs.(4.92 ± 0.31) mg/g,t =5.629,P＜0.01;perigenital:(3.50 ±0.29) mg/g vs.(2.08 ±0.13) mg/g,t =4.552,P ＜0.01] compared with normal feedindg rats,and the protein expression of phosphorylated eNOS in aortic tissues was significantly reduced to week 16 (F =15.215,P ＜0.01);high-fat diet feeding after weaning further increased the body weight and fat mass in breastfed overfeeding rats.At week 16,continuous overfeeding rats showed hypertension [(149 ± 1.94) mmHg (1 mmHg =0.133 kPa),F =22.834,P ＜0.01],impaired vascular endothelial dilation function (F =7.648,P ＜ 0.05),and reduced protein expression of phosphorylated eNOS (F =15.215,P ＜ 0.01),while the post-weaning overfeeding group only had elevated blood pressure.Conclusions Overfeeding in breastfeeding period and high-fat diet after weaning leads to hypertension.The continuous decrease in phosphorylated eNOS in vascular tissues may be an important molecular process participating in the occurrence of vascular endothelial dysfunction in adults induced by postnatal overfeeding.

Objective To investigate the significance of glomerular deposition of C4d in accessing the severity and prognosis of IgA nephropathy. Methods A total of 131 patients were recruited for the study. Immunofluorescence was used to detect the deposition of C4d in renal tissue of pa?tients with IgA nephropathy,and the relationship between C4d deposition and clinical and pathological parameters and renal remission was ana?lyzed. Results Totally 30 patients had glomerular deposition of C4d. Compared with the patients without C4d deposition,the patients with C4d deposition had significantly higher levels of serum creatinine,urinary protein excretion and C4d and higher prevalence of hypertension,but had sig?nificantly decreased levels of glomerular filtration rates. With the histopathological phenotypes segregated by Lee 's classification,the ratios of C4d deposition presented an increase(P=0.005). The patients with C4d deposition had more severe mesangial proliferation,endocapillary hypercellu?larity,segmental glomerulosclerosis and tubular?interstitial injury. The rates of renal remission were significantly lower in IgA nephropathy patients with C4d deposition than those without C4d deposition(P<0.001). Conclusion IgA nephropathy patients with C4d deposition have more se?vere clinical and pathological manifestations and lower rate of renal remission. Glomerular C4d deposition is expected to be an important pathologi?cal prognostic factor for predicting the prognosis of IgA nephropathy.
