Objective To investigate the expression levels of selenoprotein genes in the patients with coronavirus disease 2019(COVID-19)and the possible regulatory mechanisms.Methods The dataset GSE177477 was obtained from the Gene Expression Omnibus,consisting of a symptomatic group(n=11),an asymptomatic group(n=18),and a healthy control group(n=18).The dataset was preprocessed to screen the differentially expressed genes(DEG)related to COVID-19,and gene ontology functional annotation and Kyoto encyclopedia of genes and genomes enrichment analysis were performed for the DEGs.The protein-protein interaction network of DEGs was established,and multivariate Logistic regression was employed to analyze the effects of selenoprotein genes on the presence/absence of symptoms in the patients with COVID-19.Results Compared with the healthy control,the symptomatic COVID-19 patients presented up-regulated expression of GPX1,GPX4,GPX6,DIO2,TXNRD1,SELENOF,SELENOK,SELENOS,SELENOT,and SELENOW and down-regulated ex-pression of TXNRD2 and SELENON(all P＜0.05).The asymptomatic patients showcased up-regulated expres-sion of GPX2,SELENOI,SELENOO,SELENOS,SELENOT,and SELENOW and down-regulated expression of SELP(all P＜0.05).The results of multivariate Logistic regression analysis showed that the abnormally high expression of GPX1(OR=0.067,95％CI=0.005-0.904,P=0.042)and SELENON(OR=56.663,95％CI=3.114-856.999,P=0.006)was the risk factor for symptomatic COVID-19,and the abnormally high expres-sion of SELP was a risk factor for asymptomatic COVID-19(OR=15.000,95％CI=2.537-88.701,P=0.003).Conclusions Selenoprotein genes with differential expression are involved in the regulation of COVID-19 development.The findings provide a new reference for the prevention and treatment of COVID-19.

Objective:To investigate any anti-aging effect of repeated transcranial magnetic stimulation (rTMS) and explore the relationship between the effect and relief of clinical symptoms in patients with Parkinson′s disease (PD).Methods:A total of 108 PD patients were randomly divided into an rTMS group and a control group, each of 54, while another 54 healthy counterparts were selected to form a normal group. In addition to anti-PD drug therapy, the rTMS group was given daily rTMS treatment, 5 days a week for 4 weeks, while the control group received sham rTMS treatment, with no treatment of the normal group. Before the treatment and after 4 weeks of treatment as well as and 1 month after the ending of the treatment, the subjects′ clinical exercise symptoms were evaluated using the Unified Parkinson′s Disease Rating Scale (UPDRS), a timed exercise test and the 10m re-entry exercise test. Non-exercise symptoms were assessed using the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA) and the Mini-mental State Examination (MMSE). Fasting venous blood samples were analyzed to quantify the serum levels of tumor necrosis factor (TNF), interleukin-6 (IL-6), interleukin-1β (IL-1β) and matrix metalloproteinase-3 (MMP-3).Results:Four weeks and 1 month after the treatment, the average UPDRS scores, exercise test times and 10m re-entry exercise test results of the rTMS group were significantly better than those before treatment and significantly better than those of the control group at the same time point. The rTMS group′s average HAMA, HAMD and MMSE scores, as well as its average P300 latency and amplitude were also significantly better than those of the control group at the same time point and significantly better than those before treatment. After 4 weeks, the average MMP-3 content in the rTMS group was significantly lower than the control group′s average, and after a month the average levels of TNF, IL-6, IL-1β and MMP-3 of the rTMS group were all significantly different from those before treatment and those of the control group. The TNF, IL-6, IL-1β and MMP-3 levels were all positively correlated with the average UPDRS total score.Conclusion:High-frequency rTMS therapy can change the phenotypes related to cell senescence, and thus has good therapeutic effect on motor and non-motor symptoms of PD.

Nonalcoholic fatty liver disease (NAFLD) has become one of the main causes of chronic liver diseases worldwide and is closely associated with metabolic syndrome. In-depth studies on the pathogenesis of NAFLD in recent years have shown that autophagy is a highly conservative process in eukaryotes and plays an important role in the progression of NAFLD, and therefore, it is expected to become a new target for the treatment of NAFLD. This article reviews the research advances in autophagy-related signal molecules in NAFLD, in order to provide new ideas for the treatment of NAFLD.

Objective To discuss the predisposing causes and echocardiographic findings of abnormal cardiac calcifications in fetuses.Methods The echocardiographic and pathological data of 12 fetuses with abnormal cardiac calcifications were retrospectively reviewed,and the pregnancy outcome,predisposing cause and echocardiographic features were analyzed.Results Associated maternal positive anti-SSA/SSB antibody was found in 8 fetuses.The echocardiographic findings of these 8 fetuses were extensive hyper-echogenic thickened atrial wall,interatrial septal and atrioventricular roof.Cardiac myocardium dystrophic calcification was found in 3 fetuses with focal or extensive hyper-echogenic of myocardium.Idiopathic infantile calcification with thickening and hyper-echogenic wall of main pulmonary artery and aorta with obvious stenosis of artery were observed in 1 fetus.One fetus with dystrophic myocardium calcification was continued in pregnancy,1 maternal anti-SSA/SSB antibody (+) baby was born,and 10 fetuses were terminated.Conclusion Maternal anti SSA/ SSB antibody (-) is predominantly associated with fetal cardiac calcification.Fetal abnormal cardiac calcification with different predisposing causes have different echocardiographic features.

Objective To evaluate the effects of different depths of sedation on postoperative cognitive function in elderly patients with mild cognitive impairment.Methods A total of 100 patients with mild cognitive impairment before surgery,aged 65-75 yr,weighing 55-75 kg,of American Society of Anesthesiologists physical status Ⅱ or Ⅲ,scheduled for elective gynecological surgery under general anesthesia,were divided into Ⅰ and Ⅱ groups (n =50 each) using a random number table method.Propofol was given by closed-loop target-controlled infusion,and the target plasma concentration was automatically regulated.The bispectral index value was maintained at 40-50 in group Ⅰ and at＞50-60 in group Ⅱ.Mini-Mental State Examination (MMSE) and Montreal Cognitive Assessment (MoCA) were used to evaluate the cognitive function at 1 day before operation (T0) and 7 days after operation (T1),and the development of postoperative cognitive dysfunction (POCD) was recorded.Venous blood samples were collected at T0 and T1 for determination of the concentrations of serum interleukin-10 (IL-10) and tumor necrosis factor-alpha (TNF-α) by enzyme-linked immunosorbent assay.Results Compared with the baseline value at T0,MoCA and MMSE scores were significantly decreased at T1,and the serum concentrations of IL-10 and TNF-α were increased in both groups (P＜0.05).Compared with group Ⅰ,MoCA and MMSE scores were significantly decreased at T1,and the incidence of POCD was increased,the serum concentration of TNF-α was increased,and the serum concentration of IL-t0 was decreased in group Ⅱ (P ＜ 0.05).Conclusion Maintaining BIS value at 40-50 during operation can decrease the development of POCD in elderly patients with mild cognitive impairment,which may be related to reduced systemic inflammatory responses.

Objective To analyze literature related to quality of life of inflammatory bowel disease (IBD) patients from 2006 to 2016 in China, and to provide information service and reference for further clinical research.Methods Chinese databases such as China BioMedical Literature Database (CBM), China Knowledge Resource Integrated Database (CNKI), Wanfang database and Dayi Medical Database were retrieved for literature from January 2006 to December 2016 about IBD patients' quality of life. Literature area distribution, age distribution, literature types and other aspects were analyzed through literature metrology. Results Through retrieval, 55 articles were screened in the quality of life of patients with IBD related literature. The number of papers showed a linear upward trend from 2006 to 2016, and first authors were mostly from Jiangsu Province, Beijing city and Zhejiang Province, accounting for 43.64％ of the total literature. The number of descriptive literature was the largest in the literature types, 17 of the total (30.91％). The number of coauthors was up to eight, and the rate of coauthors was 1.82％. There were 5 articles cited more than 10 times (10.91％). The research content was mostly relevant to reflect self-efficacy, anxiety, depression and quality of life (16.36％). A total of 18 papers were funded (32.73％). The top 5 journals in the number of documents belong to the statistical source journals.Conclusions In the past 10 years, IBD patients' quality of life has attracted the attention of researchers in our country, but the overall degree of recognition still needs to be improved. At the same time, the overall quality of the literature is not high, and the dominant strength of research has not yet been formed. In the future, we should enrich the research methods and improve the output of high-quality literature.

Objective To observe the neural protection of 3-n-butylphthalide (NBP) injection in focal cerebral ischemia-reperfusion rats. Methods 160 male Sprague-Dawley rats were randomly divided into sham group (n=10), ischemia-reperfusion group (IR group, n=50), high-dose NBP treatment group (high-dose group, n=50), middle-dose NBP treatment group (middle-dose group, n=25) and low-dose NBP treatment group (low-dose group, n=25). The later 4 groups were occluded the middle cerebral artery for 2 hours and reperfused. The sham group was sacrificed 24 hours after operation, and the other groups at 6, 12, 24, 48 and 72 hours after reperfusion, in which 5 of them were stained with TdT mediated dUTP Nick End Labeling (TUNEL) to observe the neuronal apoptosis, and immunohistochemistry to observe the expression of silent information regulation 2 homolog 1 (SIRT1) and peroxisome proliferator-activated receptorγcoactivator-1α(PGC-1α);the other 5 of sham group, IR group and high-dose group were observed with quantitative real-time PCR of SIRT1 and PGC-1α. Results Compared with the IR group, the number of apoptotic cells decreased and the SIRT1 and PGC-1αpositive cells increased in all NBP groups at each time (F>160.60, P<0.001), and it was the least of apoptotic cells and most of SIRT1 and PGC-1α positive cells in the high-dose group (P<0.05), while there was significant difference between the low-dose group and the middle-dose group, excluding 6 hours after reper-fusion (P<0.05). Compared with IR group, the expression of SIRT1 and PGC-1αmRNA increased in the high-dose group at each time (t>4.13, P<0.01). Conclusion NBP can protect brain from apoptosis in focal cerebral ischemia-reperfusion rats, which may relate to more ex-pression of SIRT1 and PGC-1α.

OBJECTIVETo observe the law of the meridian abnormal changes and the correlation with acupuncture efficacy based on the effectiveness study of electroacupuncture (EA) in treatment of severe functional constipation.

METHODSSeventy patients of severe functional constipation were randomized into an EA group and a sham-EA group, 35 cases in each one. In the EA group, Tianshu (ST 25) and Fujie (SP 14) were punctured deeply and stimulated with EA (dense-disperse wave, 2Hz/15 Hz, 0. 1 to 1. 0 mA), and Shangjuxu (ST 37) was needled. In the sham-EA group, the sites lateral to Tianshu (ST 25) and Fujie (SP 14) were punctured shallowly and stimulated with electricity. The site lateral to Shangjuxu (ST 37) was punctured shallowly. The treatment was given continuously for 8 weeks in the two groups, 5 times weekly in the first 2 weeks and 3 times weekly in the rest 6 weeks. WANG Juyi's meridian examination method was applied to detect the abnormalities of the spleen, stomach and large intestine meridians before treatment, and in 2, 4, 6 and 8 weeks among 70 patients separately. The frequency of complete spontaneous bowel movement (CSBM) every two weeks, meridian abnormal value and the relativity with CSBM change rate were compared in the patients between two groups.

RESULTSRegarding the increase of CSBM frequency, the effect started since the 2nd week in the EA group, with the treatment going on, CSBM frequency was increased apparently (all P<0. 05). In the sham-EA group, after 6 and 8-weeks of treatment, CSBM frequency was increased apparently as compared with that before treatment (all P<0. 05). The increase of CSBM frequency in the EA group was remarkably as compared with the sham-EA group at every time point (all P<0. 05). The abnormal value of the large intestine meridian in 2 weeks of treatment and the values of the stomach and spleen meridians and the relevant meridians in 4 weeks of treatment were all reduced apparently as compared with those in the baseline in the EA group (all P<0. 05). With the treatment time going on, the abnormal reflections on the large intestine and stomach meridians were reduced gradually (all P<0. 05), and the total change rate of abnormalities on the large intestine, stomach and spleen meridians presented the negative correlation with the total change rate of CSBM frequency (P<0. 01, P<0. 05).

CONCLUSIONIn the EA group, the efficacy on CSBM frequency in severe functional constipation is advantageous and stable as compared with the sham-EA group. Acupuncture at the relevant acupoints of the spleen, stomach and large intestine meridians achieves the definite regulation to the meridian abnormalities. It is discovered that the abnormal changes in the spleen, stomach

Objective To study the preventive effect of nursing risks management for pancreatitis after ERCP. Methods From August 2012 to July 2014,a total of 200 patients treated with endoscopic retrograde cholangiopancreatography ( ERCP) in our hospital were selected and divided into control group using the routine nursing intervention and observation group using the risk nursing management of nursing intervention. We compared the incidence of pancreatitis and nursing effects between two groups after ERCP. Results After operation, patients of observation group occurred no incidence of pancreatitis, while nursing satisfaction was 99. 0%; the incidence of pancreatitis was 6. 0% and nursing satisfaction was 71. 0% in the control group (χ2 =6. 19, 31. 75;P<0. 05). After nursing interventions, the length of hospitalization was (6. 8 ± 2. 5)d in the observation group compared (10.7 ±4.1)d in the control group (t=6.45, P<0.05). The anxiety score in the observation group was (42. 7 ± 5. 9), lower than (53. 2 ± 7. 1) in the control group (t=4. 69, P < 0. 05 ). Conclusions The nursing risks management can significantly reduce the incidence of pancreatitis after ERCP and the total incidence of complications, shorten the hospitalization time of patients, improve the patient′s level of anxiety and the patients′satisfaction of nursing.

Objective To study the relationship between the semen quality and age in infertile men in Qingyuan.Methods 727 cases of infertile men from Reproductive Medicine Center outpatient were enrolled and divided into 5 groups:≤ 25,> 25 - 30,>30-35,>35-40,>40 age groups.The semen characteristics were carried out by calculator assistance sperm analysis(CASA) technique and Diff-Quick staining method.Results The sperm density of >30 -35 age group was the highest,but there was no significantly difference from other groups(P >0.05).Semen analysis showed that the rates of PR,PR+NP and survival sperm were on downward trends with the increase of age,but not statistically significant(P >0.05).38.19% of >25 -30 age group reached WHO′s semen parameters standard,which was the highest proportion among 5 groups.And the proportion in >40 age group was the lowest,which counted for 27.42%.Conclusion The semen quality shows a down trend with the increase of age,however,the infertility could occur in the reproductive men at any stage.
