ObjectiveTo compare the difference effects on the proximal stomach in rapid(intake rate 100 mL/min) and slow(intake rate 15 mL/min) LNLT.Methods Forty healthy subjects received both the rapid and slow LNLTs.The caloric density of the nutrient was 1 kcal/mL. The TVDRI and MVDRI were recorded,and the corresponding TVPS and MVPS were measured by B-ultrasound.Results(1) There were positive correlation was identified between TVDRI and TVPS,and between MVDRI and MVPS in both slow and rapid LNLTs.(2) TVDRI and MVPS in slow LNLT were significantly smaller than those in rapid LNLT,but MVDRI was significantly larger in slow LNLT than that in rapid LNLT.(3) TVDRI was much closer to TVPS in slow LNLT than those in rapid LNLT.But MVDRI was much closer to MVPS in rapid LNLT than those in slow LNLT.Conclusion Both slow and rapid LNLTs could be used to evaluate the accommodation to a meal and visceral sensitivity of the proximal stomach.The visceral sensitivity is related to the accommodation function.TVDRI of slow LNLT is more sensitive in estimating the visceral sensitivity of the proximal stomach;MVDRI of rapid LNLT is more accurate in estimating the accommodation of the proximal stomach.

Aim To explore the hemodynamic change of elderly isolated hypertension(EISH). Methods Color doppler ultrasonography were applied to examine thirty EISH patients and twenty eight elderly healthy subjects. The left ventricular systolic function as well as hemodynamic parameters were measured. Results The indices of left ventricular systolic function in EISH group such as SV,CO,EF and CI were obviously higher than those of control group(P<0.05),Linear relevant analysis show that pulse pressure was remarkable related to SV,CO,EF and CI in EISH group,with r value 0.43,0.56,0.46,0.45 respectively.Conclusion EISH patients apparently had ventricular systolic dysfunction and hemodynamic abnormality. Pulse pressure may be associated with development of sysytolic dysfunction.

Objective To Investigate correlation between screening assay of human papillomavirus (HPV) and microbial pathogens in gynecology. Methods Cervical samples were collected to search for HPV, bacteria and yeast infections in gynecologic outpatients. HPV typing was carried out by PCR and sequencing on cervical brush specimens. Chlamydia trachomatis was identified by strand displacement amplification (SDA) and the other microorganisms were detected by conventional methods. All data were analyzed to investigate the correlation among them. Results In this cross-sectional study, among 857 enrolled outpatients, there were 266 cases with positive HPV DNA, and the rate of infection was 31.0%(266/857). HPV genotype showed that thirty-five different HPV types were identified, of which HPV16 was the most prevalent ( 14.5%, 38/262), followed by HPV58 (9.2%, 24/262), HPV53 (8.0%, 21/262)and HPV42 (6.1%, 16/262); while other genotypes were present in less than 5% of HPV positive women.According to the reclassification, the aggregated percentage (high-risk and probably high-risk) of detected HPV was 58.8% ( 154/262), 27.9% (73/262) for low-risk and 13.4% (35/262) for unknown-risk HPV types. Among HPV positive women, cervical brush specimens results showed that more than 60% cases with normal cytology, 3.8% (10/266) with high-grade squamous intraepithelial lesions (HSIL), 29. 7% (79/266) with low-grade squamous intraepithelial lesions (LSIL) and 3.0% (8/266) with atypical squamous cells of undetermined significance (ASCUS), respectively. Statistical analyses revealed there was a significant association between the infected HPV and Chlamydia trachomatis or Ureaplasma urealyticum ( >10000 CCU/ml; all P <0.01), while no correlation was found between HPV infection and bacterial vaginosis, streptococcus agalactiae, candida, Trichomonas vaginalis or Ureaplasma urealyticum ( ≤ 10000CCU/ml; all P > 0.05 ). Among the cases with bacterial vaginosis, the positive rate of HPV infected was42.6%. Chlamydia trachomatis was one of the high-risk factors for the infection of HPV ( OR = 2.82, 95%CI: 1.74 -4.57). Mycoplasma hominis was isolated only in 2 cases, no patient was infected with Neisseria gonorrhocae. Conclusions Although bacterial vaginosis was not significantly associated with HPV, it was more common among the HPV positive women. There is the significant association between HPV and Chlamydia trachomatis or Ureaplasma urealyticum which may be increase the infection of HPV. These data suggest that it may be important to screen for the simultaneous presence of different microorganisms which may have synergistic pathological effects.

Objective To construct a recombinant fusion protein with pneumococcal surface pro-tein A (PspA) of Stretococcus pneumonia (SPN) familyⅠclade 1 and 2, and to analyze the immunogenici-ty of the fusion protein.Methods The gene fragments encoding theα-helix of PspA of the two clades were amplified by PCR and then inserted into the expression vector pET-27b(+) to construct the recombinant ex-pression plasmid.The transformed Escherichia coli BL21 strains carrying expression plasmid were induced by IPTG to express the recombinant protein.The titers and affinity of antibodies against PspA protein were measured by ELISA.An opsonophagocytic assay and an animal experiment were performed to evaluate the immunogenicity of the recombinant protein.Results Double enzyme cutting and gene sequencing confirmed the two purpose gene fragments were correctly expressed in the expression vector pET-27b(+).The titers of anti-PspA antibody in the serum of Kunming ( KM) mice immunized with the fusion protein were 1 ×104 . The affinity of anti-PspA antibody reached to 2×105 .The rates of recombinant PspA6B-PspA05 protein me-diated phagocytosis for SPN6B, SPN05 and SPN01 strains were 20%, 15% and 8.8%, respectively.No SPN23F strain was engulfed by macrophages upon the stimulation with PspA6B-PspA05 protein.The survival rates of mice injected with SPN05, SPN6B, SPN01 and SPN23F strains were respectively 75%, 92%, 75%and 33%upon the immunization of PspA6B-PspA05 protein.Conclusion The recombinant fusion protein PspA6B-PspA05, constructed with the PspA proteins of Stretococcus pneumonia familyⅠclade 1 and 2, was successfully expressed in the E.coli prokaryotic system with the advantage of high immunogenicity.High ti-ters of anti-PspA antibodies with high specificity were induced in KM mice upon the stimulation with Ps-pA6B-PspA05 protein.Moreover, a cross-protective immunity was induced in KM mice upon the immuniza-tion with PspA6B-PspA05 protein.

Objective: To evaluate the radiological tumor response patterns and compare the response assessments based on immunebased therapeutics Response Evaluation Criteria in Solid Tumors (iRECIST) and RECIST 1.1 in metastatic clear-cell renal cell carcinoma (mccRCC) patients treated with programmed cell death-1 (PD-1) inhibitors. Materials and Methods: All mccRCC patients treated with PD-1 inhibitors at Henan Cancer Hospital, China, between January 2018 and April 2019, were retrospectively studied. A total of 30 mccRCC patients (20 males and 10 females; mean age, 55.6 years; age range, 37–79 years) were analyzed. The target lesions were quantified on consecutive CT scans during therapy using iRECIST and RECIST 1.1. The tumor growth rate was calculated before and after therapy initiation. The response patterns were analyzed, and the differences in tumor response assessments of the two criteria were compared. The intra- and inter-observer variabilities of iRECIST and RECIST 1.1 were also analyzed. Results: The objective response rate throughout therapy was 50% (95% confidence interval [CI]: 32.1–67.9) based on iRECIST and 30% (95% CI: 13.6–46.4) based on RECIST 1.1. The time-to-progression (TTP) based on iRECIST was longer than that based on RECIST 1.1 (median TTP: not reached vs. 170 days, p = 0.04). iRECIST and RECIST 1.1 were discordant in 8 cases, which were evaluated as immune-unconfirmed PD based on iRECIST and PD based on RECIST 1.1. Six patients (20%, 6/30) had pseudoprogression based on iRECIST, of which four demonstrated early pseudoprogression and two had delayed pseudoprogression.Significant differences in the tumor response assessments based on the two criteria were observed (p < 0.001). No patients demonstrated hyperprogression during the study period. Conclusion Our study confirmed that the iRECIST criteria are more capable of capturing immune-related atypical responses during immunotherapy, whereas conventional RECIST 1.1 may underestimate the benefit of PD-1 inhibitors. Pseudoprogression is not rare in mccRCC patients during PD-1 inhibitor therapy, and it may last for more than the recommended maximum of 8 weeks, indicating a limitation of the current strategy for immune response monitoring.
