ABSTRACT

Objective:To explore the expression and clinical significance of immunosuppressive receptor T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT) on the peripheral blood mononuclear cells (PBMC) in silicosis patients with Mycobacterium tuberculosis infection. Methods:August 2018, a total of 78 patients with silicosis (all were quarry workers in Sanmen County, Zhejiang Province) were enrolled and divided into silicosis combined with active pulmonary tuberculosis group (APTB group), silicosis combined with latent tuberculosis infection group (LTBI group), and simple silicosis with non-tuberculosis infection group (non-TB group). Flow cytometry was used to analyze the expressions of TIGIT, programmed death-1 (PD-1) and transcription factor T-bet on PBMC from patients. Mann-Whitney U test and Pearson correlations analysis were used for statistical analysis. Results:Among the 78 patients, eight were in the APTB group, 24 in the LTBI group, and 46 in the non-TB group. The expressions of PD-1 and TIGIT on CD8 + T cells in the APTB group (29.45%(16.78%) and 65.40%(12.12%), respectively) were significantly higher than those in the LTBI group (17.40%(11.17%) and 48.30%(28.75%), respectively; U=23.500 and 43.500, respectively, P=0.000 8 and 0.020 5, respectively) and non-TB group (15.95%(12.46%) and 45.30%(19.75%), respectively; U=64.000 and 69.000, respectively, P=0.002 3 and 0.003 8, respectively), and the differences were all statistically significant. The expression of TIGIT was positively correlated with PD-1 on CD8 + T cells in silicosis patients ( r=0.434 3, P<0.01). The proportion of PD-1 + TIGIT + CD8 + T cells in the APTB group (19.90%(22.67%)) was significantly higher than those in the non-TB group (11.55%(11.29%), U=76.500, P=0.007 1) and LTBI group (11.55%(10.53%), U=41.000, P=0.015 4), while the proportion of PD-1 -TIGIT -CD8 + T cells in the APTB group (30.60%(12.90%)) was significantly lower than non-TB group (48.90%(18.98%), U=58.000, P=0.001 3) and LTBI group (47.20%(24.59%), U=41.000, P=0.015 4). The differences were all statistically significant. The expression of T-bet on the peripheral blood CD8 + T cells in the APTB group (29.45%(16.78%)) was higher than that in the non-TB group (15.95%(12.46%)) and the LTBI group (17.40%(11.17%)), and the differences were both statistically significant ( U=46.500 and 46.000, respectively, P=0.000 3 and 0.028 3, respectively). The expression of T-bet on CD8 + T cells was positively correlated with TIGIT on CD8 + T cells ( r=0.456 7, P<0.01). The expression of T-bet on PD-1 + TIGIT + CD8 + T cells in the APTB group (65.40%(12.12%)) was higher than those in the LTBI group (48.30%(28.75%), U=23.500, P=0.000 8) and non-TB group (45.30%(19.75%), U=65.000, P=0.002 6), and the differences were both statistically significant. Conclusion:The immunosuppressive receptor PD-1 and TIGIT are highly expressed on CD8 + T cells in silicosis patients with active pulmonary tuberculosis, which indicates CD8 + T cells exhaustion in these population, while the highly co-expression of T-bet suggests the exhausted subsets may have reversed potentiality.

ABSTRACT

Venous thromboembolism (VTE) is a common perioperative complication in patients with thoracic malignant tumor. Once it occurs, it will not only affect the prognosis of patients, but also occupy a lot of medical resources, which is gradually causing our widespread attention. However, the understanding of VTE in thoracic surgery in our country is relatively late, and the recognition and attention are not enough, and there is still a lack of guidance support for perioperative VTE. Based on the current understanding and preventive measures of VTE in thoracic surgery in China, The China National Research Collaborative Group released the first edition of Chinese experts consensus on the perioperative VTE prophylaxis in 2018. This article will interpret the high-risk patients with perioperative VTE in patients with thoracic malignant tumors, in order to provide a better understanding of Chinese experts consensus for readers.

ABSTRACT

Objective To establish the expression profiles of differentially expressed miRNA and mRNA in oral squamous cell carcinoma(OSCC)and to investigate the roles of miRNA and mRNA associated with the occurrence and development of OSCC. Methods The expression profiles of miRNA and mRNA were constructed using a new generation of high-throughput sequencing techniques. The miRNA and mRNA associated with the occurrence and development of OSCC were predicted by Gene Ontology enrichment analysis and KEGG pathway analysis. Results We successfully constructed the differentially expressed miRNA and mRNA profiles of Chinese hamster buccal pouch squamous cell carcinoma. 11 known and 3 novel significantly differentially expressed miRNAs and 194 differentially expressed mRNAs were found. A miRNA can regulate multiple mRNAs, and multiple miRNAs can control one mRNA. Conclusions Differential expression of miRNA play a an important role in the carcinogenesis and development of OSCC through regulating mRNA and forming a complex regulatory network. It provides theoretical data for the occurrence,pathogenesis,clinical treatment and prognosis of OSCC.

ABSTRACT

Objective@#To analyze the clinical characteristics of community-acquired pneumonia (CAP) in children under five years of age and analyze the safety and efficiency of nasal continuous positive airway pressure (NCPAP) ventilation for CAP in this population.@*Method@#This was a prospective multicenter study. Children who were admitted to these six centers with CAP and met the NCPAP ventilation indications, aged from 29 d to 5 years, were continuously included during November 2013 to October 2015. The baseline data were collected and NCPAP ventilation were then followed up by operation standards, and the vital signs and arterial blood gas change at special time points were observed and recorded. Any side effect associated with NCPAP were recorded. For categorical variables, comparisons were performed using Fisher test. Rank-sum test and t test were performed respectively for abnormal and normal distribution continuous variables. The variables pre-NCPAP and post-NCPAP were analyzed by repeated measures ANOVA analysis.@*Result@#Totally 145 children were included, and 13 children were excluded due to incomplete data. One hundred and two children(77.3%)were ≤12 months; 91 children (68.9%) were from rural area. NCPAP ventilation was effective in 123 children, with a response rate of 93.2%, were all discharged with a better condition; it was ineffective in 9 children(6.8%), and they were all intubated and went on mechanical ventilation, 5 were discharged with a better condition, and 4 died after gaving up treatment. The gender, age, body weight, residence, main symptoms, main signs, imaging diagnosis, medications, partial pressure of oxygen(PaO2), breath and heart rate before NCPAP treatment of two groups had no significant differences(allP>0.05). The rates of combining underlying diseases, trouble with feeding and cyanosis, and the partial pressure of carbon dioxide(PaCO2 ) before NCPAP ventilation were higher in NCPAP ineffective group ((59±11 )vs.( 49±11) mmHg, 1 mmHg=0.133 kPa, t=-2.597, P=0.028); while the PaO2/fraction of inspiration O2 (FiO2 ) before NCPAP was lower((150±37) vs. (207±63) mmHg, t=2.697, P=0.008). The breathing, heart rate and PaCO2 of NCPAP effective group decreased significantly, while the PaO2 and PaO2/FiO2 increased significantly after 2, 8, 24 h of NCPAP ventilation(all P=0.000). PaCO2 in children with hypercapnia before NCPAP ventilation in NCPAP effective group decreased significantly ((48±9), (47±12), (45±11)vs.(58±7)mmHg, all P=0.000). All children tolerated well to NCPAP ventilation, and there were no severe side effects or complications associated with NCPAP ventilation.@*Conclusion@#NCPAP ventilation is safe and effectively improved the oxygenation and hypercapnia in infants with CAP. But it may not work well in children with underlying diseases, manifest as difficulty in feeding/cyanosis and extremely high PaCO2 or low PaO2/FiO2, and they may need early intubation.

ABSTRACT

Objectives To investigate the efficacy of the shear wave velocity (SWV) based on acoustic radiation force impulse (ARFI) elastography in the differentiation of normal population with chronic kidney disease (CKD) and acute kidney injury (AKI) in middle aged and elderly patients.Methods Sixty-four middle aged and elderly patients referred to China-Japan Friendship Hospital and Zhejiang Provincial People's Hospital with AKI or CKD were enrolled in this study from February 2015 to December 2016 (kidney disease group).Among them,43 patients were CKD (CKD group),and 21 patients were AKI (AKI group,15 patients combined with prior CKD,6 patients without prior CKD).Twenty-nine middle aged and elderly healthy volunteers from China-Japan Friendship Hospital were enrolled at the same time (healthy control group).The SWV values of the renal middle pole cortex were acquired using the ARFI elastography.The differences of the kidney length,cortical thickness and SWV values among healthy control group,AKI and CKD group were compared by variance analysis.The LSD-t analysis was used for the advanced comparison between any two groups.The differences of cortical SWV values among healthy control group,AKI combined with prior CKD group,AKI without prior CKD group and CKD group were compared by variance analysis.The LSD-t analysis was used for the advanced comparison between any two groups.The receiver operating characteristic (ROC) curves of the cortical SWV values for diagnosing kidney disease was drawn.Results The mean cortical SWV values of healthy control group,AKI and CKD groups were (2.88±0.63),(2.42±0.83) and (2.06±0.72) m/s,respectively.The SWV values of AKI and CKD groups were significantly lower than that of healthy control group (t=2.158,P=0.033;t=5.234,P < 0.001).The SWV values of CKD group were lower than that of AKI group,but there were no significant differences.The SWV values of AKI without previous CKD group and AKI combined with prior CKD group were (2.60±0.84) and (1.80±0.45) m/s,respectively.The SWV values of AKI combined with prior CKD group and CKD group were significant lower than that of healthy control group and AKI without prior CKD group (compared with healthy control group:t=2.916,P=0.004 and t=5.318,P < 0.001;compared with AKI without prior CKD group:t=2.054,P=0.043 and t=-2.517,P=0.013).But there were no significant differences between AKI combined with prior CKD group and CKD group,so as to the AKI without prior CKD group and healthy control group.The cutoff value of cortical SWV for diagnosing kidney disease was 2.40 m/s,with an area under ROC curve was 0.767 (95% CI 0.689-0.898,P=0.000).The sensitive and specificity were 57.1% and 81.9%,respectively.Conclusions The SWV values of kidneys in middle aged and elderly CKD and AKI patients were significantly lower than those of apparently normal kidneys.The SWV values of AKI patients combined with prior CKD were lower than AKI patients without prior CKD.Determining cut-off SWV values based on ARFI elastography between normal and damaged renal parenchyma can help in the diagnosis of kidney disease in middle aged and elderly patients.

ABSTRACT

Objective To study the expression and significance of apoptosis-related genes caspase-3,caspase-9,Bax and Bcl-2 in oral normal mucosa,oral simple hyperplasia,oral epithelial dysplasia and oral squamous cell carcinomas (OSCC) in Chinese hamsters.Methods The expressions of mRNA and protein of caspase-3,caspase-9,Bax and Bcl-2 in the oral normal mucosa,oral simple hyperplasia,oral epithelial dysplasia and OSCC tissues in Chinese hamsters were examined by immunohistochemistry and RT-PCR.Results During the process of oral carcinogenesis,the expression of Bcl-2 protein was significantly higher in OSCC than in oral normal mucosa,oral simple hyperplasia,and oral epithelial dysplasia (P<0.05).In dysplastic epithelia,the protein expressions of caspase-3,caspase-9 and Bax were more than that of normal epithelia,and along with the increased dysplasis,the expression level was decreased.Further analysis showed that expression of Bcl-2 was negatively related with the expressions of Bax,caspase-3 and caspase-9 (P<0.05).The result of RT-PCR showed that Bcl-2 was significantly increased in OSCC compared with normal mucosa,while the expressions of caspase-3,caspase-9 and Bax were decreased (P<0.05).Conclusions In the Chinese hamster squamous carcinoma,the expressions of caspase-3,caspase-9 and Bax are reduced and the Bcl-2 expression are increased,indicating that the expressions of caspase-3,caspase-9,Bax and Bcl-2 are closely related with the occurrence and development of oral squamous cell cancinoma.This study can offer some clues for gene therapy of OSCC,or can provide a reference for evaluating the biological characteristics and prognosis of OSCC.

ABSTRACT

Objective The clinical manifestations of Parkinson''s disease (PD) are divided into non-motor symptoms and motor symptoms.Constipation is one of the common symptoms of non-motor symptoms of the disease.Constipation symptoms in PD generally occur earlier for 5~20 years, while drug treatment for PD constipation can lead to gastrointestinal damage.This study investigated the improvement in the treatment of anorectal dynamics and constipation symptoms in Parkinson''s disease by oral mosapride and press-needle therapy of Shu-Mu point.Methods 60 patients diagnosed as constipation of Parkinson''s disease were randomly divided into control group and treatment group, 30 cases in each group;patients in the control group were treated with oral mosapride tablets, while patients in the treatment group received press-needle therapy, three times per week.The observation course in both groups last for three months and follow-up visits were conducted before and after the course.Efficacy evaluation, PAC-QOL scale and anorectal dynamic examination were applied in the follow-up visit.Results The efficiency of treatment group was 81.7%, significantly higher than control group (70%), representing significant difference between the two groups (P0.05).As to the anorectal dynamics, significant difference was found before and after the treatment in both groups (P0.05).Conclusion Both oral mosapride and press-needle can improve the quality of life and anorectal dynamics for PD patients, representing no significant difference.However, compared with mosapride, the overall efficacy of press-needle is better in improving the symptoms of constipation in PD, featuring more convenience, higher safety, less pain and no side effect, and it is worthy of clinical application.

ABSTRACT

Objectives To explore the route of ESBL producing bacteria in neonatal faeces, and to investigate the gene and drug resistance of ESBL producing bacteria in intestinal tract of neonates. Methods Fecal samples of healthy newborns and their mothers were collected, and bacterial cultures were carried out using selective ESBL medium. The positive strains were identified by Time-of-flight mass spectrometry. ESBL genotyping and resistance gene detection were performed by whole genome sequencing technique. Results In 146 neonatal fecal specimens, the positive rate of ESBL producing bacteria was 8.90%,and the positive rate in the first time stool was 3.23%. Seventy-two hours after birth, the positive rate of fecal ESBL producing bacteria was 13.10%. Among the 13 ESBL producing strains, there were 9 strains of CTX type, 3 strains of TEM type and 1 strain of SHV type. Nine strains of CTX include five types such as CTX-M-24, CTX-M-18, CTX-M-27, CTX-M-42 and CTX-M-15. The positive rate of ESBL producing bacteria was 21.6% in 167 mothers' fecal specimens. The ESBL genotype included 24 strains of CTX type, 6 strains of TEM type, 4 strains of SHV type and 2 strains of QnrS type. Twenty-four strains of CTX include CTX-M-24, CTX-M-14, CTX-M-18, CTX-M-27, CTX-M-42 and CTX-M-15. There were 2 or 3 ESBL genotypes in 12 maternal and neonatal specimens. It was detected to have 6 types of resistance gene such as aadA5, strA, strB, sul1, sul2 and dfrA17 in 49 strains of ESBL producing bacteria in maternal and neonatal strains. Resistance genes were exactly the same in the neonates as in mothers who were detected to have ESBL producing bacteria. A variety of resistance genes were detected in feces in 7 neonates and 23 mothers. Conclusions The neonates in hospital may be detected to have ESBL produing bacteria in the intestinal tract at the same time as their mothers or separately. However, there are many ways for neonates to have ESBL producing bacteria in intestinal tract. There are many genotypes and resistance genes of ESBL producing bacteria.
