Objective:To explore the effects of sitagliptin phosphate combined with metformin on blood glucose control and microinflammation in patients with type 2 diabetes.Methods:One hundred patients with newly diagnosed type 2 diabetes who were treated in the First Affiliated Hospital of Xingtai Medical College from March 2017 to March 2019 were randomly divided into observation group (50 cases) and control group (50 cases). The observation group was treated with sitagliptin phosphate combined with metformin for 8 weeks, while the control group was treated with metformin for 8 weeks. The changes of fasting blood-glucose (FBG) and blood glucose 2 h after meal (2 h-PBG ) in the two groups before and after treatment were observed, and the standard time of FBG and 2 h-PBG in the two groups were statistically analyzed. The levels of interleukin(IL)-1, IL-6 and high-sensitivity C-reactive protein (hS-CRP) were compared between the two groups before and after treatment.Results:After treatment, the levels of FBG and 2 h-PBG in the observation group were significantly lower than those in the control group: (6.32 ± 0.83) mmol/L vs. (7.21 ± 1.03) mmol/L, (8.61 ± 1.26) mmol/L vs. (9.63 ± 1.12) mmol/L, and the standard time of FBG and 2 h-PBG in the observation group were significantly shorter than those in the control group: (3.11 ± 0.86) weeks vs. (4.53 ± 1.31) weeks, (3.26 ± 0.36) weeks vs. (9.63 ± 1.12) weeks, and the differences were statisticlly significant ( P<0.05). After treatment, the serum levels of IL-1, IL-6 and hs-CRP in the observation group were significantly lower than those in the control group: (22.86 ± 4.07) ng/L vs. (35.13 ± 5.92) ng/L, (5.93 ± 0.84) ng/L vs. (9.67 ± 1.11) ng/L, (2.12 ± 0.25) ng/L vs. (3.57 ± 0.48) ng/L, and the differences were statistically significants ( P<0.05). Conclusions:Sitagliptin phosphate combined with metformin in the treatment of type 2 diabetes patients can rapidly and effectively control blood glucose and improve the state of microinflammation in patients.

Objective To explore the effects of different processing parameters of mobile digital radiography (DR) on image quality of bedside chest radiography.Methods Post processing parameter on 150 cases bedside DR chest image like multi frequency laplasse transform (MLT),image processing (IP) were modified,and the optimization scheme of post-processing parameters were analyzed and summarized.The paired sample t test was used to compare the difference of the imaging quality score and optical density between the default parameter group and the post processing parameter optimization group through measure the optical density of lung related area.Results Brightness,contrast and the low density in dynamic range were the main factors affecting the quality of bedside chest radiography.After modifying and optimizing the post-processing parameters,the density value of the second intercostal area was 1.68±0.04,the density value of the hilum was 0.77±0.46,the density value of pulmonary peripheral (near chest wall 1 cm and overlap with a single rib) was 0.62± 0.06,the density value of cardiac shadow was 0.44 ± 0.04,the density value of subphrenic was 0.37 ± 0.04,the lung markings was clearly showed in the lateral field of lung and was visible in the spine and heart shadow area which meet the diagnostic requirement.The density value of those parts before modify were lower than the modify value which was more closer to the reference density value,and the difference had statistically significant.The image quality score of the postprocessing parameter optimization group was 3.53 ± 0.14,which was higher than 3.02 ± 0.23 of the default parameter group,and the difference had statistically significant.Conclusion The appropriate post-processing parameters is the key to guarantee the reasonable density of lung areas image quality and the optimization post-processing parameter can improve the image quality of bedside chest radiography by the mobile DR.

Objective Genomic alterations and potential neoantigens for cervical cancer immunotherapy were identified in a cohort of Chinese patients with cervical squamous cell carcinoma(CSCC). Methods Whole-exome sequencing was used to identify genomic alterations and potential neoantigens for CSCC immunotherapy.RNA Sequencing was performed to analyze neoantigen expression. Results Systematic bioinformatics analysis showed that C>T/G>A transitions/transversions were dominant in CSCCs.Missense mutations were the most frequent types of somatic mutation in the coding sequence regions.Mutational signature analysis detected signature 2,signature 6,and signature 7 in CSCC samples.PIK3CA,FBXW7,and BICRA were identified as potential driver genes,with BICRA as a newly reported gene.Genomic variation profiling identified 4,960 potential neoantigens,of which 114 were listed in two neoantigen-related databases. Conclusion The present findings contribute to our understanding of the genomic characteristics of CSCC and provide a foundation for the development of new biotechnology methods for individualized immunotherapy in CSCC.

OBJECTIVETo study the relationship between body mass index (BMI), hypertension and all-cause mortality in the elderly population in Beijing.

METHODSIn 1992, a cohort of 3 257 people above 55 years old was selected from 3 different areas of Beijing, i.e. urban and suburbs (both plain and mountain areas). Information on physical condition, history of chronic diseases, self-perceived health, as well as smoking and drinking status was collected. Blood pressure, body height and weight were measured among 2 086 of 3 257 subjects.

RESULTSBMI was decreasing with age, while the prevalence of hypertension increased with age. Meanwhile the prevalence of hypertension increased with age as well as with BMI. There was a reverse relationship between BMI and all-cause mortality, i.e. the risk of death was 39.0% lower for those with BMI = 20.0 - 24.9 kg/m(2) (Hazard ratio: 0.61, 95% Confidence interval: 0.49 - 0.75) and 62% lower for those with BMI >/= 25.0 kg/m(2) (Hazard ratio: 0.38%, 95% Confidence interval: 0.29 - 0.49) than those with BMI < 20.0 kg/m(2). After controlling for age, gender, residential place, hypertension as well as self-perceive health status and cognition function, low BMI remained a significant and independent predictor to death.

CONCLUSIONThe distribution of BMI was different in elderly from the youth. The findings suggested that it was important to control the body weight among the elderly hypertensives.

The inflammatory response is involved in the pathogenesis of the most common types of heart disease.Sanguinarine (SAN) has various pharmacological properties such as anti-inflammatory,antioxidant,antibacterial,antitumor,and immune-enhancing properties.However,few studies have investigated the effects of SAN on lipopolysaccharide (LPS)-induced inflammatory and apoptotic responses in H9c2 cardiomyocytes.Therefore,in this study,H9c2 cells were co-treated with SAN and LPS,and the mRNA levels of pro-inflammation markers and the apoptosis rate were measured to clarify the effect of SAN on cardiac inflammation.The underlying mechanism was further investigated by detecting the activation of Toll-like receptor (TLR)4/nuclear factor-κB (NF-κB) signaling pathways.As a result,increased mRNA expression of interleukin (IL)-1 β,IL-6,and TNFα induced by LPS was attenuated after SAN treatment;LPS-induced apoptosis of H9c2 cardiomyocytes and cleaved-caspase 8,9,3 were all significantly reduced by SAN.Further experiments showed that the beneficial effect of SAN on blocking the inflammation and apoptosis of H9c2 cardiomyocytes induced by LPS was associated with suppression of the TLR4/NF-κB signaling pathway.It was suggested that SAN suppressed the LPS-induced inflammation and apoptosis of H9c2 cardiomyocytes,which may be mediated by inhibition of the TLR4/NF-κB signaling pathway.Thus,SAN may be a feasible therapy to treat sepsis patients with cardiac dysfunction.

OBJECTIVE: To detect pathogenic variant in a juvenile with severe type Cornelia de Lange syndrome (CdLS). METHODS: A 12-year-old female presented with comprehensive developmental retardation and deformity of lower limbs. Genomic DNA was extracted from peripheral blood sample of the patient. Whole exome sequencing was performed to identify pathogenic variants. Putative variant was verified by Sanger sequencing. The impact of variants was predicted and validated by bioinformatic analysis. RESULTS: A de novo missense variant, c.1507A>G (p. Lys503Glu), was found in the NIPBL gene of the proband. The variant was unreported previously and predicted to be pathogenic by PolyPhen-2, MutationTaster and SIFT. Using HomoloGene system, the 503 loci in the NIPBL protein are highly conserved. The change of amino acid (Glu), locating in 503 locus, was found to cause the Neuromodulin_N superfamily domain destroyed, resulting in severe damage to the function of NIPBL protein. CONCLUSION The de novo missense variant c.1507A>G (p. Lys503Glu) of the NIPBL gene probably underlies the disease in this patient.

Objective:To analyze pathogenic variant s of KMT2A gene in a child with Wiedemann-Steiner syndrome (WDSTS) and provide reliable evidences for clinical diagnosis of WDSTS. Methods:Whole-DNAs were extracted from an 9 years-old boy and his parents. Trio-whole exome sequencing (trio-WES) was performed to identify candidate pathogenic variants that can explain the boy’s condition and sanger sequencing was conducted to prove it. The impact of detected variants were predicted and validated by bioinformatics tools.Results:A de novo frameshift variant c. 10488dupG (p.Leu3498Thrfs*41) in exon 27 of KMT2A gene was detected and this de novo variant (PS2) had not been reported in the world previously. This frameshift variant was absent in major allele frequency databases (PM2) and had been predicted to be pathogenic based on MutationTaster. Through HomoloGene and CD-search system, the 3498 locus (Leu) in KMT2A protein, which was an important histone modifying enzyme that regulated gene expression in early embryonic development and encoded by the KMT2A gene, was predicted as a high conserved locus (PP3), and that replacement of Lue3498 may result in frame-shifts with premature termination in 3539 locus by introducing stop codon, causing deletion of multiple functional domains which all played important roles on histone modifications and recognition (PVS1+ PM1). According to the American College of Medical Genetics and Genomics variant classification guideline, the variant c. 10488dupG (p.Leu3498Thrfs*41) in KMT2A was classified as pathogenic variant (PVS1+ PS2+ PM1+ PM2+ PP3). Conclusion:The patient’s condition may be attributed to the de novo frameshift variant c. 10488dupG (p.Leu3498Thrfs*41) in KMT2 A gene. This study reported a pathogenic KMT2A variant that had not been reported previously in WDSTS, it expanded the genotypic spectrums of KMT2A variants.

Prepulse inhibition (PPI) is suppression of the startle reflex when an intense startling stimulus is preceded by a weaker sensory stimulus (the prepulse). It is an operational measurement of sensorimotor gating mechanism to help human adapt to complex environment. This weak prepulse protect central cognitive processing by damping the effect of intense stimuli. Autistics cannot select out behaviorally important information from a lot of irrelevant resources and reflect abnormal gating mechanism and attentional abnormalities. Previous studies have not made agreement on whether autistic patients demonstrated deficits in PPI, because the results depend on age, sex, severity of the disease as well as the experimental parameters used. Moreover, these studies have not covered whether autistics have suffered deficits in higher-order processing. In this review, the "top-down" modulation of selective attention and subjective emotion are introduced into the PPI experiment. We also introduce fear conditioning and perceived spatial separation paradigm to further explore the interaction between autistic cognitive process and gating mechanism.

BACKGROUNDUroacitides is a group of cell differentiation inducers, which is purified from fresh human urine. Preclinical studies of Uroacitides have showed that cancer cells could be induced to differentiate, and the growth of cancer cells could be inhibited by Uroacitides. The aim of this study is to compare the efficacy and toxicity between Uroacitides combined with NP regimen and NP alone in treatment of advanced non-small cell lung cancer (NSCLC).

METHODSForty-two cases of advanced NSCLC were randomized into Uroacitides+NP and NP groups. NP group: NVB 25mg/m² on days 1 and 8, DDP 75mg/m² on day 1. Uroacitides combined with NP group: Uroacitides of 300mL was given through subclavian catheter daily for 7 days prior to the NP chemotherapy, then concurrently with NP regimen for 2 cycles, except the days of administration of chemotherapy.

RESULTSIn the Uroacitides+NP group, the overall response rate was 44.4%, and 20.0% in the NP group (P > 0.05). The median survival time was 9 months in the Uroacitides+NP group and 6 months in the NP group (P=0.0287). The main toxicities were myelosuppression, gastrointestinal reaction and alopecia, and there was no significant difference in incidences of toxicities between the two groups (P > 0.05).

CONCLUSIONSUroacitides combined with NP regimen shows a good curative effect and low toxicity, and may significantly prolong the median survival time for advanced NSCLC.

BACKGROUNDMany studies have reported the benefit of hepatic resection for solitary and metachronous metastases from gastric cancer. However, indications and surgical results for synchronous hepatic metastases from gastric carcinoma have not been clearly defined. This study was performed to assess the benefits and limits of simultaneous combined resection of both primary gastric cancer and synchronous hepatic metastases, as well as to identify prognostic factors affecting the survival.

METHODSBetween January 2005 and June 2008, 13 patients with synchronous hepatic metastases underwent simultaneous combined resection. The clinicopathologic features and the surgical results of the 13 patients were retrospectively analyzed. Patient, tumor (primary and metastatic carcinoma), and operative parameters were analyzed for their influence on survival.

RESULTSNo patient died and two patients (15.4%) developed complications during peri-operative course. The actuarial 6-month, 1-year, and 2-year survival rates after hepatic resection were 76.9%, 38.5%, and 30.8%, respectively, and two patients survived for more than 2 years after surgery without any signs of recurrences until latest follow-up. In univariate analysis, hepatic tumor distribution (P=0.01) and number of hepatic metastases (P=0.003) were significant prognostic factors that influenced survival. Factors associated with the primary lesion were not significant prognostic factors.

CONCLUSIONSSatisfactory survival may be achieved by simultaneous combined resection of both primary gastric cancer and synchronous hepatic metastases in strictly selected patients. The number of hepatic metastases and hepatic tumor distribution are significant prognostic determinants of survival.
