ABSTRACT
Objective:To retrospectively analyze the clinical and serological characteristics in rehabilitated patients with common novel coronavirus pneumonia(COVID-19).Methods:A total of 165 patients with common COVID-19 were enrolled in this retrospective study, in which clinical data was collected from February 23 to March 15, 2020 in Leishenshan Hospital(Wuhan, China). The patients with COVID-19 were divided into elderly group and non-elderly group according to their age, and the differences in the clinical and serological metabolic characteristics between these two groups were analyzed.Results:49.7% patients were over 60 years old. The most common clinical symptoms were fever, cough, and fatigue, followed by muscle soreness. Expectoration and digestive tract symptoms were rare. Dyspnea occurred more frequently in the elderly group than in non-elderly group(47.56% vs 25.30%, P<0.01). Hypertension was the most common concomitant disease(accounting for 29.1%)followed by diabetes. Hypertension was more common in the elderly group than in non-elderly group(41.46% vs 16.86%, P<0.01), but without significant difference in diabetes between the two groups. The counts of leukocytes and lymphocytes in all patients were in the normal range, and no difference was observed between the groups. The comparison of serological indicators showed that serum creatinine in the elderly group was higher than that in the non-elderly group( P<0.01)while serum albumin, glomerular filtration rate, and serum calcium were lower in the elderly group. After serum albumin correction, the levels of albumin corrected calcium in all patients were in the normal range, without significant difference between these two groups. There was no significant difference between the two groups when the length of hospital stay was taken as the index of outcome [(34.01±10.24) vs(30.97±10.51)d, P>0.05]. Conclusion:Fever, cough, and fatigue are the most common clinical symptoms in patients with ordinary COVID-19. The elderly are more likely to develop dyspnea. The blood routine and metabolic characteristics in patients with common COVID-19 are normal, but serum albumin level is more likely to decrease in elderly patients with COVID-19.
ABSTRACT
Objective To investigate the expression of circular RNA (circRNA) in peripheral blood of gravidas with gestational diabetes mellitus (GDM) using gene chip technology, and to provide evidence for studying pathogenesis of GDM. Methods A prospective cohort-based nested case-control study was used to select 1 018 pregnant women who were examined and delivered in Guangzhou Women and Children's Medical Center from September 2014 to April 2016. The information of prenatal examination was recorded and the outcome of delivery was followed up. Six pregnant women diagnosed as GDM were selected as the GDM group. Six normal pregnant women who were collected blood samples by 1 ∶ 1 were selected as the control group. The difference of gestational week was less than 7 days, the number of previous pregnancies was less than 2 times, and the difference of previous delivery times as same as the control group. The expression of circRNA in maternal peripheral blood was analyzed by chromosome microarray technique, and the function and the regulation network forecast were analyzed by GO (http://www.geneontology.org/), KEGG PATHWAY (http://www.genome.jp/kegg/pathway.html) and CircNet(http://circnet.mbc.nctu.edu.tw/). t-test was used for data analysis. ResuLts Compared to the normal pregnant women, 2 678 circRNAs were identified to be differentially expressed >2.0 times in GDM women, among which 1 532 were up-regulated and 1 146 were down-regulated. Functional analysis showed that the up-regulated circRNA was enriched in the biological processes of insulin response, gene silencing regulation, glucagon response and cell senescence. Signal pathway analysis showed that circRNA involved in insulin pathway. Taking has_circ_0042852 and has_circ_0004001 as center, the possible GDM-related regulatory networks were predicted. ConcLusions The peripheral blood of GDM women is rich in circRNAs, which might involve in many biological processes, insulin signaling pathway and possibly induding GDM-related regulatory networks.
ABSTRACT
The changes of carotid intima media thickness (cIMT) in type 2 diabetic patients with vitamin D insufficiency and subclinical macrovascular disease after 12 months' intervention therapy with calcitriol were observed.86 patients with vitamin D insufficiency [25 (OH) D＜30 ng/ml] and subclinical macrovascular disease were randomized to group A (n =44,treated with 0.5 μg/day calcitriol) or group B (n =42,blank control) for 12 months.40 patients in each group completed the follow up.After 12 months of therapy with calcitriol (0.5 μg.qd.po.),levels of high sensitive-Creactive protein,sCD36,and cIMT were significantly decreased,while 25 (OH) D and ankle brachial index were significantly increased (P＜0.05) in group A,suggesting that calcitriol could improve cIMT in patients with vitamin D insufficiency and subclinical macrovascular disease.
ABSTRACT
Objective To evaluate the levels of high-sensitivity-CRP(hs-CRP),interleukin-10(IL-10) in patients with obstructive sleep apnea-hypopnea syndrome (OSAHS).Methods Fifty cases with obstructive sleep apnea-hypopnea syndrome from Jul.2012 to Dec.2013 in the People's Hospital of Pudong New Area were selected as our subjects,of which,22 patients were with mild-moderate OSAHS and 28 patients were with severe OSA.Twenty-seven health people were served as control group.The levels of hs-CRP,IL-10 were measured.Information of sleep study and other clinical characteristics were collected.Results There were no significant differences in terms of age,hip circumference and waist-to-hipratio (WHR) among three groups (P ＞0.05).Body mass index (BMI),neck circumference,waist circumference,Apnea-Hypopnea Index (AHI),the lowest arterial oxygen saturation(SaO2％) and hs-CRP in mild,severe OSA and control group were (28.01 ±3.41),(28.55±2.87) and (5.51±3.28) kg/m2,(41.18±4.37),(41.46±3.32) and (38.76±2.66) cm,(101.86±8.05),(102.32±7.97) and (94.56±10.25) cm,(44.55±16.26),(10.54±7.08) and (2.02 ±1.51) time/h,(85.05±6.40)％,(72.85±15.07)％,(88.59±3.43)％,(8.35±2.71),(9.19±2.85),(7.06 ± 1.30) mg/L,and the differences were significant(P＜0.05).In patients with OSA,SaO2％ was related to BMI (r =-0.274,P =0.027) and AHI (r =-0.651,P ＜ 0.001).Level of hs-CRP was associated with AHI (r =0.336,P =0.006) and BMI (r =0.247,P =0.047),and weakly associated with IL-10 concentrations.Conclusion Levels of hs-CRP is an important inflammation marker of OSAHS severity.However,levels of IL-10 shows an increasing in mild-moderate OSA patients,then decreasing in patients with severe OSA.

ABSTRACT
Objective:To assess the therapeutic effects and adverse reactions of MS Contin in the treatment of acute myocardial infarction (AMI). Methods: 42 AMI patients were divided into experiment group and control group. Experiment group were given oral administration of MS Contin for 1 week besides the routine treatment of AMI for patients in the control group. Results: Between the two groups, the differences in the product of heart rate and blood pressure ( HR?BP) , the frequency of angina pecto-ris attack, the recovery time of the ST segment and the incidence of acute arrhythmia were significant. The most common side effects observed were: vomiting, constipation, hallucination, and the most severe toxic side effect was respiratory inhibition. Conclusion : In the treatment of AMI, MS Contin could relieve the pain effectively, reduce the incidence of angina pectoris attack and severe arrhythmia, decrease myocardial oxygen consumption, have tolerable side effects in the majority of patients. It is preferable to use MS Contin as a concurrent treatment of AMI.
ABSTRACT
In terms of technology,modern development of a hospital is increasingly reliant on the update of medical equipment,the fixed assets of which have now taken up 50%～70%of the total,increasing from 20～30% formerly.It is not unusual that a hospital promotes the overall level of technology in one aspect through introducing an advanced equipment.So the revenue brought by the adoption of medical equipment has increased inevitably,and will keep the trend with more momentum.Therefore,it is becoming more and more important to do the maintenance of the equipment well.This article presents the requirements,goal and procedure of enterprise-pattern management of medical equipment in a hospital and makes exploration in the field of hospital modern management concerning medical equipment.
ABSTRACT
OBJECTIVE: To investigate the therapeutic mechanism of tetromethylpyrazine and aminoguanidine on diabetic nephropathy. METHODS: Diabetic rats were induced by streptozotocin. They were divided into 5 groups: normal control group (group C), untreated diabetic group (group DM), tetromethylpyrazine treated group (group TMP), aminoguanidine treated group (group AG) and tetromethylpyrazine and aminoguanidine treated group (group TMP+AG). The expression of vascular endothelial growth factor (VEGF) in renal cortex of the rats in each group was observed by immunohistochemical staining after 12 weeks. RESULTS: The expression of VEGF in renal cortex of the rats in group TMP+AG and group C was alike. The expression of VEGF in renal cortex of group TMP and group AG decreased significantly as compared with that of group C, but was still above normal level. CONCLUSION: The therapeutic mechanism of tetromethylpyrazine and aminoguanidine on diabetic nephropathy may be inhibiting the over-expression of VEGF in kidney of diabetic rats.

ABSTRACT
Objective:To investigate the couse of 24 cases AVB during RFCA and 5 cases after RFCA in total 94 AVNRT patients. Methods:94 AVNRT patients received RFCA in which time, the energy and power were gradually discussed. The correlation among AVB and both different anatomical positions (upper, middle and lower zone) and A/V, H-value in intraventricular ablation mapping were studied respectively. Results: With the elevation of ablation zone, the AVB risk was also increased. The intraventricular ablation mapping showed that:①Increase of A/V and H-value means higher AVB risk;② Simultaneous increase of A/V and H-value would lead to the most dangerous result. Conclusion:It is of great importance to perform RFCA under such situation:middle and lower zone as ablation positions multiple-peak A wave, A/V(0.1-0.25) and no H or slightest H(≤0.02?0.03)mV are present in intraventricular ablation mapping, which could significantly lower the risk of RFCA-related AVB.

ABSTRACT
Objective:Atrioventricular nodal reentrant tachycardia(AVNRT) is a common type of arrhythmia,for which radiofrequency ablation(RFCA) is the first therapeutic option.This study is to investigate the causes of 16 cases of temporary atrioventricular block(AVB) during RFCA and 2 cases of permanent AVB after RFCA in common and refractory AVNRT.Methods: We performed RFCA for 77 AVNRT patients by gradually increasing the ablation time,energy and frequency.Generally we chose the lower zone as the first position of ablation and,if invalid,moved the catheter gradually up to the middle or upper zone.Then we analyzed the correlation of AVB with A/V and H-wave in different positions.Results: The AVB risk was increased with the upward movement of the ablation zone and increase of A/V or H-wave(P 0.05). Conclusion: The method of gradually increasing the ablation time,energy and frequency can prevent temporary from permanent AVB.In the common AVNRT group,the middle and lower zone ablation,the multiple-peak A wave,small A wave and big V wave(A/V ≤ 0.45?0.37) with no H wave or H≤0.003?0.01 mV could significantly decrease the risk of RFCA related AVB,but the risk of AVB remains among the refractory AVNRT patients with CSO abnormality or expansion,even if with ablation in the lower zone.
