OBJECTIVETo observe the intervening effects of Xuezhikang Capsule (XZK) on levels of blood lipid and other related indices in patients with different Chinese medical syndrome patterns of non-alcoholic fatty liver disease complicated carotid atherosclerosis (NAFLD-CAS), and to seek out the most appropriate pattern to indicate XZK for making guidance of its utilization.

METHODSChinese medical syndrome in 74 patients of NAFLD-CAS were classified into 4 patterns, 34 of Pi-deficiency phlegm-dampness pattern (A), 24 of dampness-heat accumulation pattern (B), 12 of phlegm-stasis intertwined pattern (C), and 4 of Gan-Shen yin-deficiency pattern (D). Excepting those of pattern D were excluded due to too small samples, all patients were treated with XZK for 3 months. Blood levels of blood lipids, including triglyceride (TG), total cholesterol (TC), and low-density lipoprotein cholesterol (LDL-C), as well as high-sensitivity C-reactive protein (hs-CRP), and tumor necrosis factor alpha (TNF-alpha) were detected and compared before and after treatment.

RESULTSThe effective rate of XZK on patients of the three patterns, in A-C order, was 97.06%, 91.67%, 91.67%, respectively, with the optimal overall efficacy showed on pattern A. All the indices detected significantly decreased after treatment in all three patterns (P < 0.01), among them, excepting the difference of TG level between groups showed no significance (P > 0.05), the decrements of others were more significant in pattern A than in other two patterns (P < 0.05 or P < 0.01).

CONCLUSIONXZK could reduce the levels of blood lipids, hs-CRP and TNF-alpha in NAFLD-CAS patients, and the Pi-deficiency phlegm-dampness syndrome pattern was the optimal indication of XZK treatment.

Objective To observe the effectiveness and safety of Linggui Zhugan Decoction in the treatment of metabolic syndrome(MS) induced by antipsychotics.Methods Sixty MS patients were enrolled who also matched the diagnostic criteria for phlegm stagnation type.These 60 patients who were treated in the Second Affiliated Hospital of Xinxiang Medical University were randomly divided into the observation group and control group,each group included 30 patients.The patients in the observation group were given the treatment of Linggui Zhugan Decoction in addition to antipsychotic treatment,while the patients in the control group were only given antipsychotic treatment.After two weeks or four weeks of treatment,the levels of triglyceride (TG),high density lipoprotein (HDL),fasting plasma glucose,insulin,C-peptide and insulin resistance index (HOMA-IR) were compared between the two groups before and after treatment.Results After two weeks or four weeks treatment,the levels of TG,fasting plasma glucose,insulin,C-peptide and HOMA-IR significantly increased and that of HDL decreased significantly in the control group patients compared with those before treatment (P ＜ 0.05),while the results in the observation group were opposite (P ＜ 0.05).In the control group patients,the levels of insulin,HOMA-IR and C-peptide after four weeks treatment were significantly higher than those after two weeks treatment (P ＜ 0.05).However,in the observation group patients,the levels of insulin,HOMA-IR and C-peptide after four weeks treatment were significantly lower than those after two weeks treatment (P ＜ 0.05).Compared with the control group,after two weeks or four weeks treatment the levels of TG,fasting plasma glucose,insulin,C-peptide and HOMA-IR decreased significantly in the observation group patients and that of HDL increased significantly (P ＜ 0.05).The treatment emergent symptom scale score of the observation group was lower than that of the control group at the end of four weeks (P ＜ 0.05).Conclusion Linggui Zhugan Dcoction can improve MS caused by antipsychotics and has good safety.

OBJECTIVETo evaluate the perinatal management and outcome of different types of fetal arrhythmia.

METHODSA retrospective analysis was conducted among the fetuses with arrhythmia identified by M-mode and pulsed Doppler echocardiography in a single institution between October 2003 and December 2010.

RESULTSA total of 130 fetuses were found to have fetal arrhythmia. The most common arrhythmia during pregnancy was extrasystole (n=59), followed by bradycardia (n=23), tachycardia (n=16), atrial flutter (AF, n=3), atrioventricular block (AVB, n=12) and other arrhythmia (n=17). The overall incidence of cardiac anomalies (commonly fetal bradycardia) was 9.2% in these cases. The prognosis of arrhythmia differed significantly between cases of different classifications. The type of fetal arrhythmia (P=0.024), presence of congenital heart defect (CHD, P=0.000) and fetal hydrops (P=0.008) were significant risk factors associated with termination of pregnancy.

CONCLUSIONFetal arrhythmias without CHD or hydrops under close monitoring often have good clinical outcome, while fetal bradycardia is associated with a high mortality rate. CHD and the presence of fetal hydrops are significant risk factors for pregnancy termination.

OBJECTIVETo investigate the effects of a high-carbohydrate diet on the lipid and apolipoprotein ratios in healthy young adults with different genotypes of the polymorphism at -75 site in the promoter region of the gene of apolipoprotein AI (APOA1).

METHODSFifty-six subjects aged (22.89 +/- 1.80) years were given a wash-out diet for 7 days, followed by a high-carbohydrate diet for 6 days. The wash-out diet contained 15% protein, 31% fat, and 54% carbohydrate. The high-carbohydrate diet contained 15% protein, 15% fat, and 70% carbohydrate. Twelve-hour fasting serum lipids and apolipoproteins B100 and AI were measured on the mornings of the 1st, the 8th, and the 14th days from the beginning of the wash-out diet. The ratios of triglyceride (TG)/high-density lipoprotein cholesterol (HDL-C), total cholesterol (TC)/HDL-C, low-density lipoprotein cholesterol (LDL-C)/HDL-C, and apolipoprotein B100 (APOB100)/apolipoprotein AI (APOAI) were calculated. The genome DNA was extracted and the polymorphism of APOA1 -75 G/A was determined by polymerase chain reaction followed by restriction fragment length polymorphism assay.

RESULTSAt baseline, the lipid and apolipoprotein ratios showed no significant differences between the GG genotype and the A carriers in males (P > 0.05), whereas the female A carriers had a significantly higher ratio of LDL-C/ HDL-C compared with the female subjects with the GG genotype (P < 0.05). Following the high-carbohydrate diet, significant decreases of TC/HDL-C were found in all the groups, regardless of sex and genotype (P < 0.01). LDL-C/HDL-C experienced significant decreases in both the genotypes in males (P < 0.05), while in females, significant decrease of LDL-C/HDL-C was only observed in A carriers (P < 0.01).

CONCLUSIONThe A allele of the -75 G/A polymorphism in APOA1 may have specific effects on the LDL-C/HDL-C ratio in females.

BACKGROUNDEndovascular stent-grafting is widely used to treat thoracic aortic dissection. However, little information is available regarding outcome following simultaneous exclusion of multiple tears. This report details eight years of experience using simultaneous multi-tear exclusion for treatment of Stanford type B thoracic aortic dissection resulting in successful aortic remodeling without adverse events.

METHODSFrom September 1998 to January 2006, 29 type B thoracic aortic dissection patients (24 men, 5 women; 27 chronic, 2 acute; mean age 58 years, range 45 - 77 years) were treated by simultaneous multi-tear exclusion in our center. Magnetic resonance angiography was used as the preoperative evaluation method. Different kinds of stent-grafts were used. The patients were followed up with contrast-enhanced spiral computed tomography at 6 months postoperatively and yearly thereafter.

RESULTSTwenty-nine surgeries were completed successfully using at least 2 stent-grafts per patient (range: 2 - 6, mean: 2.7). No major procedure-related complications, such as rupture, paraplegia, aortic branch ischemia or cerebral infarction, were observed. During follow-up, favorable remodeling of the aorta was observed.

CONCLUSIONSThe mid-term result of thoracic aortic dissection with simultaneous multi-tear exclusion was satisfactory. With the improvement of stent-grafts, simultaneous multi-tear exclusion should find wider application and become an optimal strategy for thoracic aortic dissection.

Objective To evaluate the antibacterial activities of severalβ-lactam/β-lactam inhibitor combinations in vitro.Methods All the clinical isolates were Enterobacteriaceae collected from hospitals and the susceptibility tests were performed using agar dilution method recom-mended by CLSI.The minimum inhibitory concentration ( MIC ) results were interpreted according to the breakpoints of CLSI (2014) guideline.The data was analyzed by software SPSS17.0.Results A total of 2166 Enterobacteriaceae were collected and were performed MIC tests.Based on the MIC results, the MIC50 and MIC90 of piperacillin to Escherichia coli were 256 , 512 μg · mL-1 , while piperacillin/tazobactam were 2 , 8μg· mL-1 , respectively.The sensitive rates of piperacillin/tazobactam to ESBLs -producing Escherichia coli and Klebsiella pneumoniae were 93.7% and 86.1%, cefoperazone/tazobactam were 91.5% and 82.5%, while cefoperazone /sulbactam were 74.4% and 58.39%. Among ESBLs -non -producing Escherichia coli and Klebsiella pneumoniae, there is not much difference between using β-lactam/β-lactam inhibitor combinations and β-lactams alone.β-lactam antibiotics have higher sensitive rates to Proteus vulgaris than Proteus mirabilis, butβ-lactam/β-lactam inhibitor combinations have no difference against them.The sensitive rate of mezlocillin/sulbactam to Morganella spp.was 97.4%, significantly higher than mezlocillin alone with sensitive rate 76.3%.The MIC90 of cefotaxime/tazobactam and ceftriaxone/tazobactam were lower than using cefotaxime and ceftriaxone alone.Conclusion β-lactam/β-lactam inhibitor combinations have greater antimicrobial activity to Enterobacteriaceae than β-lactams alone, especially for ESBLs-producing Escherichia coli and Klebsiella pneumoniae.Among them, piperacillin/tazobactam has the greatest antimicrobial activity.

Objective:To investigate the regulatory effects of mitofusin 1 (MFN1) on lipopolysaccharide (LPS)-induced Raw264.7 mouse macrophages pyroptosis and to provide reference for further study on the prevention of inflammation and fibrosis caused by macrophage dysfunction.Methods:Raw264.7 mouse macrophages were cultured in vitro and used to construct a model of LPS-induced pyroptosis. CCK-8 staining, PI staining, LDH release assay and Western blot were used to verify the Raw264.7 pyroptosis induced by LPS. MFN1 expression was detected by Western blot. DCFH-DA probe was used to detect the synthesis of total reactive oxygen species (ROS); Mito-SOX was used to detect mitochondrial ROS; JC-1 mitochondrial membrane potential was detected by fluorescence probe to reflect mitochondrial damage. Based on Ubibrowser database, it was predicted that MFN1 could bind to a variety of E3 ubiquitin ligases. Then, immunofluorescence and co-immunoprecipitation (CO-IP) were used to analyze MFN1 ubiquitination. An overexpression plasmid for MFN1 was constructed and transfected into Raw264.7 cells to detect the changes in pyroptosis and mitochondrial function. Results:LPS could induce the pyroptosis of Raw264.7 cells and mitochondrial dysfunction. MFN1 expression was decreased after LPS stimulation. Ubiquitinated MFN1 was detected by CO-IP. Ubiquitination inhibitor MG-132 inhibited LPS-induced expression of pyroptosis-related proteins including NLRP3, Pro-caspase-1, Caspase-1, IL-1β and IL-18 and improved mitochondrial function. MFN1 overexpression relieved the mitochondrial dysfunction and pyroptosis of Raw264.7 cells induced by LPS.Conclusions:The ubiquitination of MFN1 induced by LPS was involved in mitochondrial dysfunction and macrophage pyroptosis, suggesting that MFN1 was a potential target for the treatment of macrophage-induced inflammation and related diseases.

Objective To understand molecular characteristics of Japanese encephalitis virus ( JEV ) isolated from the major Japanese encephalitis epidemic areas in Sichuan Province,and to provide the foundation for JEV prevention.Methods 13 JEV strains were isolated from mosquitoes in Sichuan during 2007-2010,E genes and preM genes were sequenced and phylogenetic analyses were performed using MEGA5 molecular software.Results Phylogeoetic analysis indicated that all 13 JEV strains from Sichuan belonged to genotype Ⅰ,homologies at nucleotide level and deduced amino acid level in PreM gene were 97％-100％ and 98.7％-100％,and 97.8％-99.9％ and 99.6％-100％ in E gene,respectively.Homologies at nucleotide level and deduced amino acid level in PreM gene between 13 JEV strains and JEV isolated in 2004 in Sichuan were 96.2％-99.1％ and 97.5％-98.7％,and were 97.7％-99.6％ and 98.6％-100％ in E gene,respectively.By comparison with vaacine strains P3 and SA14-14-2,homologies at nucleotide level and deduced amino acid level were 84.1％-85.8％ and 93.7％-96.2％ in PreM gene,and were 87.6％-88.3％ and 97％-97.8％ in E gene,respectively.The neurovirulence-related 8 amino acid sites encode by E gene remained unchanged in 13 JEV strains.Conclusion JEV with genotype Ⅰ predominated in Sichuan,nucleotide sequences and deduced amino acid sequences in PreM gene and E gene were highly conserved,key neurovirulence-rerlated sites remained unchanged.It suggested currently used vaccine is still capable of preventing JEV infection.

Objective:To explore effect of Glioma-associated oncogene family zinc finger 1(GLI1)on hypoxia induced trans-formation of NR8383 to M1 phenotype and development of pulmonary hypertension(PH).Methods:Fifteen adult male Wistar rats were randomly divided into control group,hypoxia PH model group and hypoxic PH with GANT61 treatment group,with 5 rats in each group.PH related indexes of rats were detected by small animal ultrasound and right cardiac catheter experiment to determine effect of GLI1 specific inhibitor GANT61 on progression of PH.Pulmonary arterial thickness was measured by HE staining.α-SMA and M1 polarization markers TNF-α and IL-1β expressions were determined by immunohistochemistry.M1 polarization markers CD86 and TNF-α expressions were determined by immunofluorescence.GLI1 expression and NF-κB protein were detected by Western blot.mRNA expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 were detected by qRT-PCR.CHIP-PCR verified that GLI1 regulates NF-κB promoter activity.IL-12 content was detected by ELISA.Rat pulmonary artery smooth muscle cells proliferation was detected by CCK-8.Results:GLI1 inhibitor GANT61 could alleviate symptoms of PH in hypoxic rats(P<0.05).Compared with hypoxic group,inhibition of GLI1 reduced expressions of TNF-α and IL-1β in rat lung tissue(P<0.05).In cell experiments,hypoxia induced M1 polarization of NR8383 by up-regulating GLI1 to activate NF-κB pathway,GLI1 overexpression increased expressions of iNOS,CD86,TNF-α,IL-1β and IL-12 in M1 macrophages(P<0.05).NR8383 culture supernatants could stimulate pulmonary artery smooth muscle cell proliferation(P<0.05)and contribute to development of PH.Conclusion:Hypoxia activates NF-κB pathway by up-regulating GLI1 to induce M1 polarization of macrophages contributes to development of PH.

OBJECTIVE: To investigate the incidence rate and risk factors for metabolic bone disease of prematurity (MBDP) in very low birth weight/extremely low birth weight (VLBW/ELBW) infants. METHODS: The medical data of 61 786 neonates from multiple centers of China between September 1, 2013 and August 31, 2016 were retrospectively investigated, including 504 VLBW/ELBW preterm infants who met the inclusion criteria. Among the 504 infants, 108 infants diagnosed with MBDP were enrolled as the MBDP group and the remaining 396 infants were enrolled as the non-MBDP group. The two groups were compared in terms of general information of mothers and preterm infants, major diseases during hospitalization, nutritional support strategies, and other treatment conditions. The multivariate logistic regression analysis was used to investigate the risk factors for MBDP. RESULTS: The incidence rate of MBDP was 19.4% (88/452) in VLBW preterm infants and 38.5% (20/52) in ELBW preterm infants. The incidence rate of MBDP was 21.7% in preterm infants with a gestational age of < 32 weeks and 45.5% in those with a gestational age of < 28 weeks. The univariate analysis showed that compared with the non-MBDP group, the MBDP group had significantly lower gestational age and birth weight, a significantly longer length of hospital stay, and a significantly higher incidence rate of extrauterine growth retardation ( CONCLUSIONS A lower gestational age, hypocalcemia, extrauterine growth retardation at discharge, and neonatal sepsis may be associated an increased risk of MBDP in VLBW/ELBW preterm infants. It is necessary to strengthen perinatal healthcare, avoid premature delivery, improve the awareness of the prevention and treatment of MBDP among neonatal pediatricians, and adopt positive and reasonable nutrition strategies and comprehensive management measures for preterm infants.
