Objective To investigate the therapeutic effect of Bidouyan Oral Liquid(BOL) on acute suppurative max-illary sinusitis(ARMS) in rabbits.Methods Modified Hinni's method was used to inducing the ARMS rabbit models.The high and low-dosage of BOL was administered by gastric gavage and penicillin V was used for the positive medicine.The white blood cells(WBC)count,neutrophil percentage,serum C-reactive protein(CRP)level,inflammatory changes of mucosa of nasal sinuses under light microscope and bacteria culture of secretion in ARMS rabbit models were observed.Results Inflammatory changes were shown in the experimental ARMS rabbits as follows:white blood cells count and neutrophil percentage increased,mucosa of nasal sinuses congested and swollen with the exfoliation of pili.After the treatment with high-and low-dosage of BOL,the above parameters in the rabbits recovered to normal,the difference being insignificant compared with penicillin V.Conclusion BOL in clinical dose can control the general and local inflammatory reaction in ARMS rabbits.

Objective To investigate the relationships between serum concentration of RBP-4 and inflammatory factors,insulin resistance in patients with gestational diabetes mellitus.Methods20 patients newly diagnosed with impaired glucose tolerance (IGT),27 patients newly diagnosed with gestational diabetes mellitus(GDM) and 50 subjects with normal glucose tolerance(NGT) were enrolled in this cross-sectional study.Additionally,another subset analysis was performed,subjects were divided on the basis of BMI into normal weight (NW) and overweight or obesity (OW/OB).Serum RBP-4 was measured with ELISA;serum concentrations of hs-CRP,free fatty acids (FFA),triglyeride(TG),total cholesterol (TC) and insulin were measured in fasting status.Insulin resistance was assessed by HOMA-IR.ResultsLn(HOMA-IR) and the concentrations of FFA,ln(hs-CRP) in IGT or in GDM were significantly higher than that of NGT(P＜0.05).In the group of OW/OB,FFA[(0.90±0.31)mmol/L vs (0.71±0.28)mmol/L,t＝2.73,P＜0.05)],ln(hs-CRP)(0.62±1.00 vs -0.17±1.07,t＝2.90,P＜0.05),ln(HOMA-IR),lnRBP(0.56±0.27 vs 0.30±0.14,t＝2.86,P＜0.05)were significantly higher than that of NW.In the group of GDM,lnRBP-4 showed a positive relationship with FFA (r＝0.231,P＜0.05)and ln(hs-CRP) (r＝0.237,P＜0.05).There was a positive relationship between lnRBP-4 and FFA(r＝0.371,P＜0.05) or ln(hs-CRP)(r＝0.247,P＜0.05) in the group of OW/OB,but no association in the group of NGT,IGT or NW.There was no relationship between lnRBP-4 and ln(HOMA-IR) in IGT,GDM and NW,while in the group of NGT and OW/OB,lnRBP-4 showed a positive relationship with ln(HOMA-IR) (r＝0.276,0.290,P＜0.05).In a multiple linear regression analysis,ln(hs-CRP),FFA or ln(HOMA-IR) was not the independent factor of lnRBP-4 in any group.ConclusionsIn patients with gestational diabetes mellitus,lnRBP-4 may be a new marker of inflammation.

One strain of Hantavirus(HV) was isolated from patients with hemorrhagic fever with renal syndrome (HFRS) in Zhejiang province and its S-segment was cloned and submitted to nucleotide sequence analysis in order to determine the type of strain and extent of genetic variation for further study on its evolution and mutation .The HV antigen was detected from mouse lungs in endemic area by direct immunofluorescene test and the HV-positive sample of mouse lung was inoculated to Vero-E6 cells to isolate virus. The total cellular RNA was extracted from infected cell culture and the S segment gene was amplicated by RT-PCR. Then, the purified PCR product was cloned into T vector for sequencing. The result showed that the full-length sequence of the S segment was 1 700 bp with one open reading frame (ORF) encoding 429 amino acids. Comparison with Hantavirus HTN type showed 85.7%-91.9% homology at the nucleotide level. In comparison with the SEO type of viruses, the homology at nucleotide level was shown to be 71.2%-75%. This new HV strain may be typed as to HTN virus and may be a new subtype of this virus.

The M and S segment cDNAs of hantavirus Z5 strain was amplified by RT-PCR,and the purified PCR products were cloned into vector pGEM-T and then sequenced.It was demonstrated that the M genome segment of Z5 was found to be 3 616 nucleotides in length with a single open reading frame encoding 1 135 amino acids.And the S genome segment was 1700 nucleotides in length with a single open reading frame encoding 429 amino acids.As demonstrated by the homologous analysis of nucleotides and amino acids,it was showed that the Z5 strain belonged to hantaan viruses HTN type and was the same subtype of the Z10 strain.It is conclouded that difference in nucleotide sequence exists between Z5 strain with other Hantavirus strains but high level of homology in amino acid sequences is still present.

Objective To investigate the clinical significance the clinical significance of the changes of ser-um tumor necrosis factor-α(TNF-α),nitric oxide(NO),interleukin-1β(IL-1β),and interleukin-6(IL-6)in pa-tients with colorectal cancer during perioperative period.Methods A total of 73 patients with colorectal cancer who underwent radical surgery in our hospital during December 2014 to December 2016 were selected as the observation group.At the same time,42 cases of healthy persons in our hospital from December 2014 to De-cember 2016 were selected as control group.The 5 mL of peripheral venous blood was collected 2 days after admission and 3 days after admission,and serum was separated.The levels of TNF-,IL-1 and IL-6 were meas-ured by enzyme-linked immunosorbent assay(ELISA).The level of NO was measured by nitric acid reduction method(mL).Results The serum levels of TNF-α,IL-1β,IL-6 content in the observation group were higher than those in the control group,and the content of NO was lower than that of control group,and the difference was statistically significant(P<0.05);there were no significant differences between the serum TNF-α,NO, IL-1β,IL-6 levels of colon and rectal cancer patients(P>0.05);TNF-α,IL-1β,IL-6 levels of patients at I and II phase were lower than those of patients at III and IV phase,while the content of NO was higher than that of patients at III and IV phase,and the difference was statistically significant(P<0.05);serum TNF-α,IL-1β, IL-6 levels after the operation were lower than those before operation,and the content of NO was higher than that before operation,and the difference was statistically significant(P<0.05).Conclusion The levels of ser-um TNF-a,IL-1 beta and IL-6 in the patients with colorectal cancer were increased with the severity of the disease,w hile the NO decreased with the severity of the disease.

Objective To study the complete genome sequence of Hantavirus ZT71 strain gene isolated in Zhejiang province and explore its evolution. nethods The total RNA was prepared from ZT71 virus infected cells and the RT-PCR products were cloned into T vector, sequenced and analyzed. Results The L, M and S segments of the strain ZT71 genome were 6530,3651 and 1753 nucleotides in length with a single open reading frame individually encoding 2151,1133 and 429 amino acids. The sequence analysis of nucleotides showed that the homology of L, M and S segments of strain ZT71 between those of other strains of Seoul virus could reach 95.5%-99.7%, 84.1%-99.6% and 88.7%-99.5%, respectively. The analysis of the deduced amino acids showed the similar result. The source of strain ZT71 could be traced from the analysis of the phylogentic trees of nucleotides and amino acids, and it should belong to Seoul type of Hantavirus which was also verified serologically. Conclusion The nucleotide sequences and deduced amino acid sequences of L, M and S segments of strain ZT71 are similar to that of those of Seoul type of Hantavirus. And Hantaan type virus used to be prevalent primarily in Zhejiang province,and it would be an endemic area of mixed type of Hantavirus since the discoveries of the viruses of Soeul type in recent years.

Objective To explore the value of transthoracic echocardiography in diagnosis of univentricle and analyze the sonogram typing. Methods The results of 66 patients with univentricle were reviewed retrospectively,and analayzed their typing connected with the reports in the literature. Results There were 3 ultrasonic types in 66 cases:①Type A(single left ventricle) 19 cases,single ventricle with left ventricular shape,residual cavity in front of it. ②Type B(single right ventricle) 38 cases, single ventricle with right ventricular form,and residual cavity in the rear.③Type C (solitary single-ventricle) 9 cases,there was only one ventricle. Thirty-one of them were treated surgically, 5 cases without operation had MRI or cardiac catheterization examination and the remaining 26 patients were only observed by echocardiography,the positive rate of diagnosis in type was 100%, the results were compared with cardiac catheterization or MRI examination and the operation: 1 cases of mixed type total anomalous pulmonary venous connection was misdiagnosed as heart-type total anomalous pulmonary venous drainage. But 1 case of descending aorta limitations narrow complicated patent ductus arteriosus(PDA), PDA was missed. The rest were completely correct diagnosis. Conclusions The transthoracic echocardiography can be used to evaluate types and all containing malformations of univentricle,and offers reliable information for operation.

Objective To investigate the diagnosis value of p16 combined with Ki67 protein in cervical lesions.Methods Totally 1 542 women with previous liquid-based cytology smear result of abnormality underwent a colposcopy-directed biopsy excision procedure.Biopsy specimens were detected by p16 and Ki67 immunostaining alongside hematoxylin and eosin (H&E) staining.A four-semiquantitative class was used to describe the immunohistochemical results.Results Biopsy results revealed 1 542 women included 473 women with negative for dysplasia (NEG),629 women with cervical intraepithelial neoplasia (CIN) Ⅰ,206 women with CIN Ⅱ,206 women with CINⅢ and 28 women with cervical squamous cell carcinoma (SCC).The averageage of this study population was 34.47 years.CINs mainly occurred in women aged 20-29 years and 30-39 years.The positive rates of p16 in NEG,CIN Ⅰ,CIN Ⅱ,CINⅢ and SCC were 15.22％,60.25％,98.06％,99.51％,100.00％ respectively,and the positive rates of Ki67 were 12.05％,63.12％,96.12％,98.06％,100.00％ respectively.p16 expression and Ki-67 expression significantly increased with disease progression (p16:r =0.758,P =0.000 ; Ki67:r =0.773,P =0.000).Expression level of p16 was positively related with Ki-67 (r =0.774,P =0.000).The positive expression rates of p16 and Ki-67 of NEG were significantly lower than those of CIN and SCC (p16:x2 =1 127.46,P =0.000;Ki67:x2 =1 316.85,P =0.000).The positive expression rates of p16 and Ki-67 were markedly higher in CIN Ⅰ than those in CINⅡ,CINⅢⅢ and SCC (p16:x2 =500.19,P =0.000;Ki67:x2 =603.23,P=0.000).Conclusion Women aged 20-39 years are key subjects for cervical cancer screening.p16 and Ki67 immunohistochemistry is important in the ancillary diagnosis of cervical lesions.

AIDS antiviral therapy (ART) has achieved great success.Originaly,AIDS had been regarded as a fatal disease,but it has become a kind of infectious disease that could be cured and administrated.Global HIV / AIDS cases were still up to about 38 million,but more than half have been effectively treated.In addition to drug treatment,at present,some new technologies and new methods,such as genome editing,have also been involved in the treatment of AIDS,and in the humanized animal experiment has shown very good results.There is no doubt that AIDS will eventually be stopped its epidemic.However,with the continuous development of AIDS antiviral treatment,the most fundamental problem is that HIV latent library has become increasingly prominent one,whether molecular therapy and hybrid cure have being developed for AIDS treatment,there are still such problem existence.Great efforts shoud be made to continuously search for new markers of latent viral cells and to reduce the latent pool.In addition,despite the prevention and treatment of AIDS has made great achievements,but the world still produces nearly 6000 cases of HIV/AIDS every day.Therefore,the development of safe and effective vaccine,whether in the field of prevention,or in clinical treatment,has its positive significance.

Hand, foot, and mouth disease (HFMD) caused by enterovirus-A71 (EV-A71) has posed heavy disease and economic burdens to young children under 5 years of age and families. Elucidating the pathogenesis of EV-A71 will provide better evidence for prevention and control for EV-A71 infection. miRNAs are a class of non-coding RNA that regulate many biological processes of host cells through manipulating mRNA translation to control the protein levels by direct binding to mRNA, meanwhile, participating the virus-host cell interaction. Here, we mainly review the current knowledge on the biogenesis of miRNA, alterations of miRNA profiles induced by EV-A71, regulation of EV-A71 replication, anti-EV-A71 innate immunity and apoptosis by miRNA direct binding EV-A71 genome or host genes. All these will facilitate understanding the role of miRNA in EV-A71-host cell interaction and pathogenesis of disease caused by EV-A71.
