ABSTRACT

Compressed sensing (CS) has been investigated in magnetic resonance (MR) parametric mapping to reduce scan time. However, the relatively long reconstruction time restricts its widespread applications in the clinic. Recently, deep learningbased methods have shown great potential in accelerating reconstruction time and improving imaging quality in fast MR imaging, although their adaptation to parametric mapping is still in an early stage. In this paper, we proposed a novel deep learningbased framework DEMO for fast and robust MR parametric mapping. Different from current deep learning-based methods, DEMO trains the network in an unsupervised way, which is more practical given that it is difficult to acquire large fully sampled training data of parametric-weighted images. Specifically, a CS-based loss function is used in DEMO to avoid the necessity of using fully sampled k-space data as the label, thus making it an unsupervised learning approach. DEMO reconstructs parametric weighted images and generates a parametric map simultaneously by unrolling an interaction approach in conventional fast MR parametric mapping, which enables multi-tasking learning. Experimental results showed promising performance of the proposed DEMO framework in quantitative MR T1ρ mapping.

ABSTRACT

Objective:To identify the risk factors for postoperative central nervous system complications (CNSC) developed in pediatric patients undergoing cardiac surgery under cardiopulmonary bypass (CPB) through determining regional cerebral oxygen saturation (rSO 2C) by near-infrared spectroscopy. Methods:A total of 60 pediatric patients with congenital heart disease undergoing elective orthodontic correction surgery under CPB, of American Society of Anesthesiologists physical status Ⅱ or Ⅲ, of both sexes, aged 6-36 months, weighing 5-19 kg, in our hospital from July 2019 to January 2020 were collected.Intraoperative bilateral rSO 2C was monitored continuously by near-infrared spectroscopy.Blood samples were taken from the central vein at 10 min after induction of anesthesia, immediately after CPB, at the end of CPB, on admission to ICU, at 4 and 8 h after entering ICU and at 1, 2 and 3 days after surgery (T 0-8) for determination of the concentrations of serum S100β protein and neuron specific enolase (NSE). At 12 months after surgery, the Pediatric Cerebral Performance Category (PCPC) score was used to evaluate the prognosis of neurological function.The patients were divided into 2 groups according to whether CNSC occurred: CNSC group and non-CNSC group.Multivariate logistic regression analysis was used to identify the risk factors for development of postoperative CNSC in pediatric patients undergoing cardiac surgery under CPB. Results:Two patients were excluded from the study.Eighteen cases developed postoperative CNSC, and the incidence was 31.0%.Compared with group non-CNSC, the minimal rSO 2 was significantly decreased, the maximal difference between pulse oxygen saturation and rSO 2C (da-rSO 2C) was increased, duration of reduction in rSO 2>25% during CPB, duration of rSO 2C<40% during CPB and duration of da-rSO 2C>50% during CPB were prolonged, and concentrations of serum S100β protein and NSE were increased at T 2-T 8 in group CNSC ( P<0.05). The results of logistic regression analysis showed that prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB were risk factors for development of postoperative CNSC. Conclusion:Prolonged duration of reduction in rSO 2C>25% during CPB, prolonged duration of rSO 2C<40% during CPB and prolonged duration of da-rSO 2C>50% during CPB are the risk factors for postoperative CNCS developed.

ABSTRACT

Galangal (Alpinia officinaruim Hance) is the rhizome of the perennial herb belonging to Zingiberaceae family. There are many active components in galangal, such as volatile oil, flavonoids, terpenoids, phenylpropanoids and glycosides, among which the content of volatile oil is higher. The bioactivities of galangal volatile oil on health effect includesanti-inflammatory, anti-hypertension, anti-oxidation and prevention of cardiovascular diseases. Cardiovascular disease (CVD) is a kind of diseases related to circulatory system, which is also called circulatory system diseases. Over the past decade, the number of people dying from CVD has increased by 12.5% worldwide, and it is now the leading cause of human death worldwide. Studies have shown that galangal volatile oil has good pharmacological effects in treating CVD. ① Regulation of glucose and lipid metabolism: studies have found that abnormal lipid metabolism can lead to obesity, diabetes, CVD and other diseases. The serum total triglyceride (TG) content in liver and serum will increase in patients with abnormal fat metabolism. The results showed that the volatile oil of galangal could increase the excretion of neutral cholesterol, significantly reduce liver TG and serum TG, and thus regulate glucose and lipid metabo?lism, prevent lipid deposition and prevent CVD. ② Improving insulin resistance (IR): inhibition of inflammatory cytokines such as IL-1, IL-6 activation and expression of TNF-α, improves IR, thereby protecting myocardium from IR-mediated damage. Through the establishment of endothelial cell injury model induced by high glucose in vitro, it was found that the volatile oil of galangal can significantly reduce the secretion of pro-inflammatory cytokines TNF-αand IL-8, and inhib?it the expression of ICAM-1 and VCAM-1 induced by high glucose, suggesting that it has protective effect on endothelial dysfunction and inflammation induced by high glucose.③Regulate blood oxygenation:during acute myocardial hypoxia, the activity of free radical scavenging system is decreased, and oxygen free radicals are produced in large quantity, which reacts with unsaturated fatty acids on the cell membrane and forms lipid peroxidation, resulting in myocardial structural damage. The results showed that the water extract of Galangal could reduce the content of MDA in blood and protect the SOD activity of ischemic and hypoxic myocardium.④ Protective effect of vascular endothelial cells (ES):ES injury is the pathological basis of some cardiovascular diseases. The results showed that the volatile oil of galangal had a protective effect on ES apoptosis. Compared with the morphology and activity of ES treated with oxidized LDL, galan?gal volatile oil could ameliorate these morphological changes and improve cell viability. ⑤ Antiplatelet agglutination:inhibit platelet aggregation and thromboxane release, improve blood circulation, and have obvious anti-thrombotic effect, which has a good effect on the treatment and prevention of cardiovascular diseases. The results showed that the volatile oil of galangal had inhibitory effect on platelet aggregation and anticoagulant effect. In conclusion, the volatile oil of galangal can be used to prevent and treat cardiovascular diseases. Based on the mechanism of CVD, this study summa?rized the role of the essential oil of Alpinia officinaruim in CVD, providing basis for the clinical application of alpiniaoffici?nalis essential oil in the prevention and treatment of CVD and the development of new drugs.

ABSTRACT

Objective:To observe the effect of modified Si Junzitang on the level of lactic acid in gastric mucosa and the expression of Carboxylic acid transporter 1(MCT1), monocarboxylic acid transporter 4(MCT4), and extracellular matrix metalloproteinase inducer (CD147)in rats with gastric precancerous lesions(GPL). Method:Seventy-four SD male rats were randomly divided into normal group (12 rats) and model group (62 rats). <italic>N</italic>-methyl-<italic>N'</italic>-nitro-<italic>N</italic>-nitrosoguanidine(MNNG)-ammonia compound method was used to establish GPL rat models, and at the 9<sup>th</sup> week, the model rats were randomly divided into model group, folic acid group(2.7 mg·kg<sup>-1</sup>), modified Si Junzitang high, medium and low dose groups(12.6, 6.3, 3.15 g·kg<sup>-1</sup>), with 12 rats in each group. After intragastric administration for 12 weeks, the general conditions of the rats were observed. Hematoxylin-eosin(HE)staining was used to observe the histopathological changes of gastric mucosa in rats, chemical colorimetry was used to detect the content of lactic acid in gastric mucosa; immunohistochemistry and real-time polymerase chain reaction(Real-time PCR)were used to detect MCT1, MCT4, CD147 protein and mRNA expression in gastric mucosal tissues. Result:Modified Si Junzitang significantly improved the pathological manifestations in GPL rats such as gastric mucosal epithelial gland structure, disorder of arrangement and cell atypia. Compared with the normal group, the lactic acid content of the gastric mucosa tissue in the model group increased significantly(<italic>P</italic><0.01), and the protein and mRNA expressions of MCT1, MCT4, CD147 significantly increased(<italic>P</italic><0.05, <italic>P</italic><0.01). Compared with the model group, the lactic acid content in each dose group of modified Si Junzitang was significantly reduced(<italic>P</italic><0.05, <italic>P</italic><0.01), and the protein expression levels of MCT4 and CD147 were also significantly reduced in each dose group of modified Si Junzitang(<italic>P</italic><0.05, <italic>P</italic><0.01). The mRNA expression of MCT4 was significantly reduced in the middle and high dose groups(<italic>P</italic><0.05, <italic>P</italic><0.01), and the mRNA expression of CD147 was significantly reduced in the high dose group(<italic>P</italic><0.05). Modified Si Junzitang showed no significant regulatory effect on MCT1. Conclusion:Modified Si Junzitang can significantly improve the abnormal histopathology of gastric mucosal epithelium in GPL model rats. Its mechanism may be related to down-regulating the overexpression of MCT4 and CD147, inhibiting lactic acid outflow, and improving the acidic microenvironment of gastric mucosal epithelium.

ABSTRACT

Aging is the process spontaneously occurred in living organisms. Cardiac fibrosis is a pathophysiological process of cardiac aging. Mangiferin is a wellknown C-glucoside xanthone in mango leaves with lots of beneficial properties. In this study, rat model of cardiac fibrosis was induced by injected with 150 mg/kg/d Dgalactose for 8 weeks. The age-related cardiac decline was estimated by detecting the relative weight of heart, the serum levels of cardiac injury indicators and the expression of hypertrophic biomakers. Cardiac oxidative stress and local inflammation were measured by detecting the levels of malondialdehyde, enzymatic antioxidant status and proinflammatory cytokines. Cardiac fibrosis was evaluated by observing collagen deposition via masson and sirius red staining, as well as by examining the expression of extracellular matrix proteins via Western blot analysis. The cardiac activity of profibrotic TGF-β1/p38/MK2 signaling pathway was assessed by measuring the expression of TGF-β1 and the phosphorylation levels of p38 and MK2. It was observed that mangiferin ameliorated D-galactose-induced cardiac aging, attenuated cardiac oxidative stress, inflammation and fibrosis, as well as inhibited the activation of TGF-β1/p38/MK2 signaling pathway. These results showed that mangiferin could ameliorate cardiac fibrosis in D-galactose-induced aging rats possibly via inhibiting TGF-β/p38/MK2 signaling pathway.

ABSTRACT

Epilepsy is a brain condition characterized by the recurrence of unprovoked seizures. Recent studies have shown that complement component 3 (C3) aggravate the neuronal injury in epilepsy. And our previous studies revealed that TRPV1 (transient receptor potential vanilloid type 1) is involved in epilepsy. Whether complement C3 regulation of neuronal injury is related to the activation of TRPV1 during epilepsy is not fully understood. We found that in a mouse model of status epilepticus (SE), complement C3 derived from astrocytes was increased and aggravated neuronal injury, and that TRPV1-knockout rescued neurons from the injury induced by complement C3. Circular RNAs are abundant in the brain, and the reduction of circRad52 caused by complement C3 promoted the expression of TRPV1 and exacerbated neuronal injury. Mechanistically, disorders of neuron-glia interaction mediated by the C3-TRPV1 signaling pathway may be important for the induction of neuronal injury. This study provides support for the hypothesis that the C3-TRPV1 pathway is involved in the prevention and treatment of neuronal injury and cognitive disorders.

ABSTRACT

OBJECTIVE@#To assess the association of polymorphisms of receptor of advanced glycation end products (RAGE) gene, monocyte to high-density lipoprotein cholesterol ratio (MHR) and variability of heart rate among patients with coronary heart disease (CHD).@*METHODS@#120 patients with CHD and 120 healthy individuals were respectively selected as the observation group and the control group. Allelic and genotypic differences of -429T>C, 1704G>T, 82G>S, MHR ratio and heart rate variability between the two groups and patients with different severity were analyzed. The correlation between their genotypes and MHR ratio and heart rate variability was analyzed.@*RESULTS@#The 82G>S polymorphism of the RAGE gene and the allelic difference between the two groups and patients with different severity were statistically significant (P< 0.05). Compared with the control group and patients with mild to moderate phenotype, monocyte, total cholesterol, triglyceride, low density lipoprotein, MHR, low frequency in the observation group and patients with severe symptoms were significantly higher, while their high density lipoprotein, standard deviation of NN intervals (SDNN), standard deviation average of NN intervals (SDANN), root mean square successive differences, percentage of differences exceeding 50ms between adjacent normal number of intervals (PMN50), high frequency (HF) were significantly lower. The gene frequencies of G-Gly-T, T-Gly-T, G-Ser-T and G-Gly-C were correlated with SDNN, SDANN, rMSSD, PMN50, HF and MHR, but negatively correlated with low frequency.@*CONCLUSION@#Polymorphisms of the RAGE gene in patients with coronary heart disease are associated with the MHR ratio and heart rate variability, which can be used as markers for the diagnosis and efficacy evaluation.

ABSTRACT

OBJECTIVE@#To explore the influencing factors of perioperative blood transfusion in the treatment of elderly femoral intertrochanteric fractures with proximal femoral nail antirotation(PFNA).@*METHODS@#The clinical data of 109 elderly patients with intertrochanteric fractures who received PFNA treatment from July 2018 to January 2020 were retrospectively analyzed. Both pelvic hip X-rays and CT plain scans were performed before surgery. All patients were diagnosed by X-ray and CT plain scan of pelvis and hip before operation. Through the statistical analysis of the basic data of patients before and during operation, the risk factors of perioperative blood transfusion were explored.@*RESULTS@#Logistic regression analysis showed that age (@*CONCLUSION@#Age, fracture type, diabetes history, and preoperative hemoglobin are independent risk factors for perioperative blood transfusion in the treatment of elderly intertrochanteric fractures with PFNA. The older the patient, the history of diabetes, the more unstable the fracture, and the lower preoperative hemoglobin, the more likely it is to require a blood transfusion, which may provide a reference for clinical perioperative blood transfusion decisions.

ABSTRACT

OBJECTIVE:To know about the co gnition level and self-medication behavior of antibiotics among urban and rural residents in Lu ’an city of Anhui province ,and to investigate its influential factors and to provide reference for promoting rational use of antibiotics. METHODS :Totally 684 urban and rural residents aged 18-80 years in Lu ’an city were randomly selected as the research objects by stage sampling method. A self-designed questionnaire was used for household survey ,involving general demographic characteristics ,antibiotics related cognitive level ,antibiotics use behavior and related influential factors ,etc. RESULTS:A total of 657 questionnaires were collected ,with effective rate of 96.1%. Among them ,305 were from urban residents and 352 from rural residents. Among the 657 respondents,38.2% were male and 61.8% were female ;their age was (50.30±13.26)years old ;44.7% of them were educated in primary school or below. 7.8% of the respondents correctly recognized that antibiotics were not effective to the virus ;12.6% knew antibiotic resistance ;55.1% thought that frequent use of antibiotics would reduce the sensitivity of bacteria to it ;23.1% said they knew the difference between prescription drugs and over-the-counter drugs;58.0% could tell at least one case of not using antibiotics. For 7 knowledge items ,75.3% of the residents in the survey area had a total score of less than 3;the cognition level of antibiotics was higher in urban areas and people with higher education level. 66.5% of the respondents had used antibiotics in the past one year,of which 61.0% obtained antibiotics by prescription 65161220。E-mail: from doctors ,50.7% purchased antibiotics by themselves in pharmacies, and 13.1% used the above two ways both. Among the people who have used antibiotics in the past year , 81.9% said they could buy antibiotics without prescription. Among the 657 respondents,49.0% said that they had to obtain prescription from doctor when taking antibiotics ;68.9% said that they would stop taking antibiotics when their symptoms improved;19.3% would increase their dosage in order to enhance the curative effect ;28.3% would change drugs frequently. Compared with urban residents ,rural residents were more likely to take antibiotics based on prescriptions by physicians [odds ratio (OR)=1.693,95% confidence interval (CI)(1.191,2.407)]. The higher the cognitive score ,the lower the behavior rate of having to prescribe antibiotics by doctors [OR =0.882,95%CI(0.785,0.991)],and they were more likely to stop taking antibiotics when symptoms improved [OR =1.163,95%CI(1.025,1.319)],and male were more inclined to increase the dosage of antibiotics to enhance the efficacy [OR =1.841,95%CI(1.214,2.792)]. The higher the cognitive score was ,the less likely they were to increase drug dosage to enhance the curative effect [OR =0.894,95%CI(0.773,1.034)],nor were they inclined to change drugs frequently [OR =0.873,95%CI(0.767,0.992)]. CONCLUSIONS :The cognition level to antibiotics of urban and rural residents in Lu ’an city needs to be improved urgently ,and reasonable antibiotic use behavior needs to be standardized. Pure knowledge of antibiotics is not necessarily related to the expected rational drug use behavior. Therefore ,in addition to health promotion for the rational use of drugs for residents ,it is also necessary to create a systematic environment that promotes the rational use of antibiotics and provide residents with multi-channel services for rational use of drugs.

ABSTRACT

Purpose@#Progressive familial intrahepatic cholestasis (PFIC) is a rare genetic autosomal recessive disease caused by mutations in ATP8B1, ABCB11 or ABCB4. Mutational analysis of these genes is a reliable approach to identify the disorder. @*Methods@#We collected and analyzed relevant data related to clinical diagnosis, biological investigation, and molecular determination in nine children carrying these gene mutations, who were from unrelated families in South China. @*Results@#Of the nine patients (five males, four females) with PFIC, one case of PFIC1, four cases of PFIC2, and four cases of PFIC3 were diagnosed. Except in patient no. 8, jaundice and severe pruritus were the major clinical signs in all forms. γ-glutamyl transpeptidase was low in patients with PFIC1/PFIC2, and remained mildly elevated in patients with PFIC3. We identified 15 different mutations, including nine novel mutations (p.R470HfsX8, p.Q794X and p.I1170T of ABCB11 gene mutations, p.G319R, p.A1047P, p.G1074R, p.T830NfsX11, p.A1047PfsX8 and p.N1048TfsX of ABCB4 gene mutations) and six known mutations (p.G446R and p.F529del of ATP8B1 gene mutations, p.A588V, p.G1004D and p.R1057X of ABCB11 gene mutations, p.P479L of ABCB4 gene mutations). The results showed that compared with other regions, these three types of PFIC genes had different mutational spectrum in China. @*Conclusion@#The study expands the genotypic spectrum of PFIC. We identified nine novel mutations of PFIC and our findings could help in the diagnosis and treatment of this disease.

ABSTRACT

Objective:To evaluate the efficacy and safety of endoscopic trans-gastric gallbladder-preserving polypectomy in treatment of gallbladder polyps.Methods:A retrospective analysis was performed on data of 25 patients with gallbladder polyps who underwent endoscopic trans-gastric gallbladder-preserving polypectomy in the endoscopy center of Zhongshan Hospital from September 2017 to August 2019. Completion of operation, operation time, postoperative hospital stay, complications and follow-up results of patients were obtained and analyzed.Results:There were 13 cases of single polyp and 12 cases of multiple polyps, 13 cases of simple gallbladder polyps, and 12 cases of polyps and gallstones. The maximum diameter of polyps was 0.2-1.5 cm. The procedure failed in 1 patient (4%) because of the severe adhesion of abdominal cavity and disappearance of gallbladder when passing through the gastric wall. Twenty-four patients (96%) were successfully treated with endoscopic trans-gastric gallbladder-preserving polypectomy. The operation time was 67.1±26.8 min (35-140 min). The median hospital stay was 4 d (2-5 d). No severe adverse events including delayed bleeding, delayed perforation, diffuse peritonitis or abdominal abscess occurred. During the median follow-up time of 8 months (0-23 months), no patient was lost, no recurrence of polyps and no severe adverse events related to metal clips occurred.Conclusion:Endoscopic trans-gastric gallbladder-preserving polypectomy shows good short-term efficacy and is technically feasible, however, long-term outcome still requires further research.

Participants were divided into an intervention and control group by independent registration, with 50 patients in each group. The control group received routine health guidance and telephone follow-ups. The intervention group underwent the health management mode of the WeChat platform combined with family participation beginning in September for six months. Dyslipidemia was managed through joint participation of family members and medical care, and the professional health management and medical team conducted real-time consultation, monitoring, follow-ups, and answered questions. A t-test was performed to compare total cholesterol, triacylglycerol, and LDL cholesterol in the two groups, and a χ 2 test was used to compare improvements in living habits in the two groups. Results:There were no statistically significant differences between the two groups before intervention ( P>0.05). After 6 months of intervention, fasting total cholesterol (6.18±0.93) mmol/L, low-density lipoprotein cholesterol (2.96±0.67) mmol/L and triglyceride (2.20±0.35) mmol/L were all lower in the intervention group than in the control group (7.17±1.07) mmol/L, (3.26±0.57) mmol/L and (2.41±0.36) mmol/L, respectively, with statistically significant difference ( P<0.05). After 6 months of intervention, the proportion of people in the intervention group (18% irregular diet, 22% lack of exercise, 26% insomnia, 14% smoking and 18% drinking) was significantly lower than that in the control group (58% irregular diet, 74% lack of exercise, 54% insomnia, 38% smoking and 42% drinking), and the difference was statistically significant ( P<0.05). Conclusions:Dyslipidemia is closely related to living habits. Through the help of the WeChat platform, family members and medical staff can participate together and effectively improve the living habits of people with dyslipidemia, so as to improve the indicators of lipid metabolism.

ABSTRACT

OBJECTIVE@#To explore the tensile mechanics and anatomical characteristics of the posterior hip capsule, and provide biomechanical and anatomical evidence for capsule repair in total hip replacement.@*METHODS@#Six bone-capsule-bone specimens were obtained from posterior hip joint of fresh frozen cadavers. The maximum strain, load, elastic modulus and load strain curves of the capsule ligament complex specimens were recorded by Instron Universal Material Testing Machine. Twelve cadaveric hip specimens were dissected to the capsule. The tensile strain of normal capsule and conventionally reconstructed capsule at 90 degrees of hip flexion were documented. The suture area of the posterior capsule was divided into nine sections, and the thicknessof different sections was measured and compared. Posterior capsule of the cadavers was repaired in conventionally way and anatomical way separately and simulated rehabilitation was conducted. The effect of rehabilitation on the repaired capsule was observed.@*RESULTS@#The load-strain curve of capsule ligament complex conforms to rheological and viscoelastic characteristics. The maximum tensile strain of the complex was (39.21±5.23)%, the maximum load was (142.06± 34.15) N, the tensile strength was (1.65±0.38) MPa, and the elastic modulus is (14.23±5.62) MPa. At 90 ° hip flexion, the tensile strain of repaired capsule was higher than that of normal capsule, and the difference was statistically significant (< 0.05). Tensile strain of conventionally reconstructed capsule is:upper part (37.0±4.9)%, middle part ( 53.3±1.1)%, lower part (68.3±6.2)%, tensile strain of normal capsule is:upper part (17.0±2.6)%, middle part (24.1±1.4)%, lower part (26.0± 4.3)% . The thickness of the posterior joint capsulein different sections is statistically significant (<0.05), and capsule at 0.5cm proximal to the femoral insertion is suitable for suture. There the average thickness of capsule is:upper part (3.48 ± 0.11) mm, middle part (2.36 ± 0.09) mm, lower part (1. 59±0.24) mm. The posterior inferior joint capsule is thinnest at (1.42± 0.02) cm proximal to the femoral insertion, and sutures should be avoided here. After simulating rehabilitation, avulsion occurred in the lower part of the posterior capsule repaired conventionally (10/12), and the anatomically repaired capsule remained intact.@*CONCLUSION@#The lower part of conventionally repaired capsule is overstretched and tends to fail. Anatomically repaired capsule conforms to tensile mechanics and is helpful to reduce the failure rate of repair.

ABSTRACT

The abnormality of mitochondrial morphology and function is closely related to the pathogenesis of many diseases. Mitochondrial fusion-fission dynamics are critical to maintain normal morphology, distribution and quantity of mitochondria, and ensure the normal activity of cells. In addition, mitochondrial autophagy (mitophagy) plays an important role in maintaining mitochondrial quality by degrading aging or damaged mitochondria. Many previous studies showed that mitochondrial dynamics and mitophagy can regulate each other to sustain mitochondrial network homeostasis. Clarifying regulatory mechanisms of mitochondrial dynamics and mitophagy is of great significance for revealing the molecular mechanism of various diseases and for the development of new drugs targeting mitochondrial dynamics proteins or mitophagy regulatory proteins. This review focuses on the role of mitochondrial dynamics and mitophagy in mitochondrial quality control, regulatory mechanism, the interplay between those two processes, and their roles in human-related diseases.

ABSTRACT

Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which first affected humans in China on December 31, 2019 (Shi et al., 2020). Coronaviruses generally cause mild, self-limiting upper respiratory tract infections in humans, such as the common cold, pneumonia, and gastroenteritis (To et al., 2013; Berry et al., 2015; Chan et al., 2015). According to the Report of the World Health Organization (WHO)-China Joint Mission on COVID-19 (WHO, 2020), the case fatality rate of COVID-19 increases with age, while the rate among males is higher than that among females (4.7% and 2.8%, respectively). Since an effective vaccine and specific anti-viral drugs are still under development, passive immunization using the convalescent plasma (CP) of recovered COVID-19 donors may offer a suitable therapeutic strategy for severely ill patients in the meantime. So far, several studies have shown therapeutic efficacy of CP transfusion in treating COVID-19 cases. A pilot study first reported that transfusion of CP with neutralizing antibody titers above 1:640 was well tolerated and could potentially improve clinical outcomes through neutralizing viremia in severe COVID-19 cases (Chen et al., 2020). Immunoglobulin G (IgG) and IgM are the most abundant and important antibodies in protecting the human body from viral attack (Arabi et al., 2015; Marano et al., 2016). Our study aimed to understand the aspects of plasma antibody titer levels in convalescent patients, as well as assessing the clinical characteristics of normal, severely ill, and critically ill patients, and thus provide a basis for guiding CP therapy. We also hoped to find indicators which could serve as a reference in predicting the progression of the disease.

ABSTRACT

Objective To evaluate the safety, feasibility, perioperative and long-term efficacy of peroral endoscopic myotomy ( POEM) for achalasia ( AC) in geriatric patients. Methods Data of 41 patients aged over 65 diagnosed with achalasia and treated with POEM in Zhongshan Hospital from August 2010 to December 2014 were retrospectively studied. Perioperative complications, preoperative and postoperative Eckardt score and pressure of the lower esophageal sphincter, esophageal reflux and clinical failure were analyzed. Results All 41 patients underwent POEM successfully, with median operation time of 42 min. Median hospitalization was 3 days. Major perioperative adverse events occurred in 4 cases ( 9. 75%) , whose hospitalization was longer than 5 days for perioperative adverse events. During median follow-up period of 40 months ( interquartile range 24-57 months) , median Eckardt score decreased from 8 to 1( P<0. 001 ) and pressure of the lower esophageal sphincter decreased from 23. 85 mmHg ( 1 mmHg=0. 133 kPa) to 9. 05 mmHg (P=0. 005). Clinical reflux occurred in 12 cases (29. 27%) and the 5-year success rate of POEM was 87. 80% (36/41). Conclusion POEM is a safe and reliable treatment for geriatric AC patients with confirmed short-term and long-term effectiveness.
