ABSTRACT

Neuromyelitis optica spectrum disorders (NMOSD) are a severe autoimmune inflammatory demyelinating disease of the central nervous system. NMOSD complicated with immune thrombocytopenia (ITP) is rare. This paper reports a case of NMOSD who was misdiagnosed as multiple sclerosis for many years, and then developed thrombocytopenia. ITP was diagnosed by perfect examination. After immunosuppression and thrombopoiesis therapy, the platelets returned to normal. The review of the case and literatures can help to improve the understanding of this kind of disease, timely diagnose and treat patients, and avoid serious complications.

ABSTRACT

Sixty general practitioners of in-service training undertaking rotation in gastroenterology department of Qingdao Municipal Hospital from July 2017 to July 2019 were randomized assigned in trial group ( n=30) and control group ( n=30). The problem-oriented mode was applied in trial group and conventional mode was applied in control group for teaching of two typical digestive diseases (upper gastrointestinal bleeding and acute pancreatitis). The formative evaluation and questionnaire survey were used to compare the teaching effects and the results of evaluation were compared with χ 2 test by SPSS 17.0 between two groups. The excellent and good rates of evaluation for the clinical psychological quality, clinical reasoning ability, doctor-patient communication ability and practice-based learning and improvement ability in trial group were significantly higher than those in the control group(χ2=7.38, P=0.03; χ2=12.96, P<0.01; χ2=23.33, P<0.01; χ2=16.14, P<0.01). Questionnaire survey showed more satisfaction towards teaching method in trial group was higher than that in control group(χ2=12.86, P<0.01); and the clinical reasoning ability, learning initiative and self-confidence in trial group were improved more markedly than those in control group(χ2=8.26, P=0.02; χ2=19.48, P<0.01; χ2=21.46, P<0.01). The problem-oriented clinical thinking teaching model demonstrates good effects on clinical comprehensive ability for general practitioners of in-service training during gastroenterology rotation, which is worth further promotion.

ABSTRACT

Objective:To investigate the diagnosis, surgical methods, perioperative treatment and surgical results of Kommerell's diverticulum with double aortic arch in infants.Methods:From December 2014 to December 2019, 22 cases of double aortic arch combined with Kommerell diverticulum were operated in our hospital, 14 males and 8 females, with an average age of (13.7±11.6) months (1-36 months) and mean body mass of (9.8±3.4)kg (5-20 kg). The children had respiratory symptoms such as asthmatic suffocation, shortness of breath, repeated respiratory tract infection and chronic cough before operation. All patients underwent cardiac CT examination. The average diverticulum was 8 mm×9 mm, in the trachea The average compression degree of the lower segment was 56%±16% (30%-80%). The distal part of the left arch was atresia and Kommerell's diverticulum was found in all patients. The operation methods were left aortic arch separation, ligament separation and diverticulectomy. In one case, tracheal stent was placed simultaneously during the operation because of severe tracheal malacia.Results:The average time in the ward was(1.4±0.8)days (1-4)days, and the average time in hospital was (6.7±2.8)days (4-13 days). The average follow-up period was (25.5±16.9) months (2-60 months). During the follow-up period, 18 children had no persistent respiratory symptoms, and 4 children had only slight respiratory symptoms.Conclusion:Kommerell's diverticulum can also be combined with double aortic arch. The operation method is to separate the aortic arch and ligament at the atresia end and resect the diverticulum at the same time. It has a good early prognosis and may eliminate the residual symptoms and late complications.

ABSTRACT

Data of 55 patients with duodenal mass lesions treated by endoscopic submucosal dissection (ESD) were retrospectively analyzed. Risk factors of delayed bleeding after ESD were explored by univariate analysis and multivariate unconditional logistic regression analysis. Duodenal delayed bleeding occurred in 5 patients (9.09%). No closure treatment under endoscopy( P=0.035) was significantly different between the delayed bleeding group and the non-delayed bleeding group. Multivariate non-conditional logistic regression showed no closure treatment under endoscopy was an independent risk factor for delayed bleeding after ESD in duodenal mass lesions ( P=0.029, OR=0.079, 95% CI: 0.008-0.776). Patients older than 60 years and who did not take endoscopic closure treatment have higher incidences of delayed bleeding after ESD. No closure treatment under endoscopy is directly related to postoperative delayed bleeding.

ABSTRACT

Objective:To explore the differences in intravascular ultrasound results in elderly coronary heart disease(CHD)patients with different uric acid levels.Methods:A total of 145 elderly patients diagnosed with CHD in our hospital from December 2017 to May 2020 were included as study subjects.Uric acid levels were measured and intravascular ultrasound examination was conducted in all patients.They were divided into different groups based on uric acid levels: Group A(uric acid≤199 μmol/L), Group B(uric acid 200~399 μmol/L)and Group C(uric acid≥400 μmol/L). Data from intravascular ultrasound-derived indexes were analyzed and compared between the three groups.Results:There was no significant difference in the degree of left main stenosis between Group A and Group B, but it was less severe in both groups than in Group C( F=5.625, P=0.039). Plaque fibrous cap thickness showed no significant difference between Group B and Group C, but it was smaller than in Group A( F=7.825, P=0.020). Group C had the largest plaque area and maximum thickness among the three groups, followed by Group B[(11.12±1.73)mm 2 and(1.76±0.24)mm]and Group A[(8.29±3.14)mm 2 and(1.38±0.09)mm]( F=6.384 and 6.827, P=0.028 and 0.015). Conclusions:Elevated uric acid levels in elderly CHD patients can increase the area and thickness of plaques, and reduce plaque fibrous cap thickness, leading to an increased risk of formation of unstable plaques, which can be life-threatening for these patients.Thus, monitoring and managing uric acid levels should be stressed in elderly CHD patients.

ABSTRACT

Objective:To investigate the effect of tegafur combined with oxaliplatin on the life cycle and serum alpha-fetoprotein (AFP) and carbohydrate antigen 242 (CA242) levels in patients with advanced gastric cancer.Methods:A total of 100 patients with advanced gastric cancer admitted to Hefei Third People′s Hospital from October 2016 to October 2019 were selected and divided into two groups according to randomization, with 50 cases in each group. The patients in the control group received calcium leucovorin and fluorouracil and oxaliplatin, and the patients in the observation group was treated with tegafur combined with oxaliplatin. The remission rate, disease control rate, median progression-free survival (PFS), median overall survival (OS), side effects and serum tumor markers AFP, CA242, carcinoembryonic antigen (CEA), carbohydrate antigen 125 (CA125), carbohydrate antigen 19-9 (CA19-9), tumor growth promoting indicators vascular endothelial growth factor (VEGF), matrix metalloproteinase (MMP)-2, MMP-9, insulin-like growth factor-1 (IGF-1), platelet endothelial cell adhesion molecule-1 (PECAM-1), microRNA (miR) 216a, miR95, miR4286 before and after treatment of the two groups were compared.Results:The remission rate in the observation group was higher than that in the control group: 42.0%(21/50) vs. 22.0%(11/50), and the difference was statistically significant ( P<0.05). After treatment, the levels of AFP, CA242, CEA, CA125, CA19-9 in the observation group were lower than those in the control group: (15.04 ± 3.65) μg/L vs. (20.65 ± 4.17) μg/L, (20.88 ± 6.37) kU/L vs.(35.46 ± 7.33) kU/L, (8.65 ± 2.13) μg/L vs.(15.39 ± 3.25) μg/L, (26.15 ± 8.49) kU/L vs. (34.16 ± 7.50) kU/L, (22.29 ± 5.80) kU/L vs. (38.81 ± 6.79) kU/L, and the differences were statistically significant ( P<0.05). The levels of VEGF, MMP-2, MMP-9, IGF-1 and PECAM-1 in the observation group were lower than those in the control group; the level of miR216a in the observation group was higher than that in the control group, and the levels of miR95 and miR4286 were lower than those in the control group, and the differences were statistically significant ( P<0.05). The median PFS in the control group was 3.0 months, the median OS in the control group was 6.6 months, the median PFS in the observation group was 3.3 months, the median OS in the observation group was 7.0 months, and the differences were no statistically significant ( P>0.05). The incidences of myelosuppression and skin damage toxicity in the observation group were lower than those in the control group: 6.0%(3/50) vs. 24.0%(12/50), 4.0%(2/50) vs. 18.0% (9/50), and the differences were statistically significant ( P<0.05). Conclusions:Tegafur combined with oxaliplatin in the treatment of advanced gastric cancer can improve the anti-cancer effect and promote the relief of the disease, and has high safety. The mechanism may be related to the inhibition of tumor growth promotion indexes and the regulation of miR.

Among them, there were 27 cases of bacterial infection NP (bacterial infection group) and 42 cases of MP infection NP (MP group). The clinical symptoms and signs, extrapulmonary complications, laboratory examination, imaging examination, treatment, outcome and follow-up were compared between 2 groups.Results:There were no significant differences in the rale rate, respiratory tone reduction rate and total fever time between 2 groups ( P>0.05); the incidence of shortness of breath in bacterial infection group was significantly higher than that in MP group: 77.8% (21/27) vs. 14.3% (6/42), and there was statistical difference ( P<0.01). There were no significant differences in the incidence of extrapulmonary complications between 2 groups ( P>0.05). The white blood cell, C-reactive protein (CRP), procalcitonin (PCT) and interleukin (IL) -10 in bacterial infection group were significantly higher than those in MP group, the tumor necrosis factor (TNF)-α and interferon (IFN) -γ in bacterial infection group were significantly lower than those in the MP group, and there were statistical differences ( P<0.05). There were no significant differences in neutrophils, lactate dehydrogenase (LDH) and IL-6 between 2 groups ( P>0.05). The time of necrosis in bacterial infection group was significantly earlier than that in MP group: (14.5 ± 4.2) d vs. (21.7 ± 6.4) d, and there was statistical difference ( P<0.05); there was no significant difference in the incidence of pleural effusion between 2 groups ( P>0.05), but the incidence of pleural effusion separation in bacterial infection group was significantly higher than that in MP group: 70.4% (19/27) vs. 2.4% (1/42), and there was statistical difference ( P<0.01). There were no significant differences in antibiotic application time, CRP recovery time and hospital stay between 2 groups ( P>0.05); the oxygen uptake rate and closed thoracic drainage rate in bacterial infection group were significantly higher than those in MP group: 88.9% (24/27) vs. 35.7% (15/42) and 25.9% (7/27) vs. 11.9% (5/42), the recovery times of WBC and PCT in bacterial infection group were significantly longer than that in MP group: (12.8 ± 4.1) d vs. (9.2 ± 2.0) d and (10.5 ± 2.5) d vs. (7.6 ± 1.9) d, the bronchoalveolar lavage rate was significantly higher than that in MP group: 25.9% (7/27) vs. 76.2% (32/42), and there were statistical differences ( P<0.01 or <0.05). There was no significant difference in the absorption time of necrotic lesions between 2 groups ( P>0.05). Conclusions:Compared with MP infection, the clinical process of bacterial infection NP is serious, the necrosis time appears earlier, and the course of disease is longer. However, most of the children with NP can obtain a good prognosis after active symptomatic and antiinfective treatment.

ABSTRACT

Objective:To analyze the causes, influencing factors and trends of dead on arrival cases in children′s Hospital in the past 5 years, aiming to provide direction and basis for reducing the dead on arrival cases of children.Methods:We collected the dead on arrival cases in the department of emergency at Shanghai Children′s Hospital from January 2015 to December 2019, classifed and analysed the gender, age, native place, death season, time of death, and possible causes of death, and then studied the correlation between above factors and the cases.Results:A total of 151 dead on arrival cases were collected.The annual number decreased year by year, and boys were more than girls in gender.Most of them were infants under 1 year old, and nonlocal children were more than Shanghai native.The above differences were statistically significant, but there was no significant difference in the distribution of death season and death time.In terms of the cause of death, perinatal diseases accounting for 33.8%(51/151), those accompanied with severe underlying diseases accounting for 39.1%(59/151), accidental death accounting for 14.6%(22/151), unexplained deaths accounting for 12.6%(19/151). Those distribution differences were statistically significant( χ2=32.497, P<0.001). Meanwhile, there were statistic differences in gender and age of the cases with severe underlying diseases( χ2=4.898, P=0.027; χ2=32.169, P<0.001), and the year and age distributions of the accidental death cases also had significant differences( χ2=16.636, P=0.002; χ2=14.727, P=0.002). Conclusion:To reduce dead on arrival cases of children, we should do a good job in perinatal health care and screening, reduce premature birth and birth defects, actively conduct propaganda to prevent children′s accidental injuries, popularize medical first aid knowledge, and strengthen children′s transport system.

ABSTRACT

Objective:To evaluate the inpatient PE incidence and thromboprophylaxis after thoracic surgery according to adjusted Caprini VTE risk assessment model.Methods:The study selected consecutively 500 patients who received thoracic surgery from first of June in consecutive three years of 2015, 2016 and 2017. We retrospectively assessed these 1 500 patients using Caprini VTE risk model and recorded baseline characteristics, postoperative prophylaxis, and PE incidence.Results:Only 19.4% of 2015-year patients received pharmacologic prophylaxis, while the rate reached up to 65.2% in 2016 and 77.2% in 2017. PE occurred on 4 cases in 2015, 1 case in 2016, and 0 case in 2017. The overall incidence of PE was 0.3%(5/1 500). The PE incidence negatively correlated with the implementation of prophylaxis( r=-0.04, P=0.07). The PE risk(odds ratio) increased 4.68 times(95% CI: 0.525-41.800) when patients did not receive prophylaxis in PE cohort. Postoperative pharmacologic prophylaxis with current dosing did not affect the drainage of chest tube after surgery. Conclusion:Implementation of an adjusted Caprini risk assessment protocol can be useful for the thoracic postoperative patients to receive appropriate thromboprophylaxis. Current pharmacologic prophylaxis protocol should be safe and enough to prevent PE after thoracic surgery.

ABSTRACT

Objective: To observe the effect of moxa-stick moxibustion plus recombinant human granulocyte-colony stimulating factor (rhG-CSF) in preventing chemotherapy infection in gastric cancer and its effect on immune function. Methods: A total of 70 patients with gastric cancer treated by chemotherapy were randomly divided into an observation group and a control group, with 35 cases in each group. The control group was given rhG-CSF, and the observation group was given additional moxa-stick moxibustion on the basis of rhG-CSF. Both groups were treated for 2 chemotherapy cycles, totally 6 weeks. The number of patients with infection, the duration of infection and the duration of continuous use of antibiotics were observed. The leukocytes and granulocytes counts, the levels of tumor necrosis factor-α (TNF-α) and interferon-γ (IFN-γ) were measured before and after treatment, and the levels of CD4, CD8 and natural killer (NK) cells were analyzed. Results: The infection rate of the observation group was significantly lower than that of the control group (P<0.05), and the duration of infection and the duration of continuous use of antibiotics were also shorter (P<0.05). After treatment, the leukocytes and granulocytes counts in the two groups were higher than those before treatment (all P<0.05). After treatment, the levels of TNF-α and IFN-γ of the patients in the two groups were improved (all P<0.05), and there were significant differences between the observation group and the control group (P<0.05). After treatment, the numbers of CD4, CD8, and NK cells in the observation group increased significantly (all P<0.05), but the changes in the control group were not significant (P>0.05). Conclusion: Moxa-stick moxibustion plus rhG-CSF can significantly reduce the incidence and severity of chemotherapy infection in gastric cancer, increase the leukocytes and granulocytes counts, and regulate the levels of inflammatory factors, which may be related to the improvement of the immune function of the patients.

ABSTRACT

Objective To analyze the identification, drug resistance and clinical significance of a rare bacterium of Bordetella holmesii ( B. holmesii) to improve its detection and clinical diagnosis and treat-ment. Methods A strain isolated from a bacteremia case was identified by bacterial culture, biochemical tests and 16S rRNA gene sequencing. Mega 7. 0 software was used to conduct a similarity analysis of 16S rRNA gene sequences between the type strains of Bordetella spp. and the isolate, and then a phylogenetic tree was constructed. Antibiotic resistance of the isolate was determined by E-test. Changes in bacterial growth were measured after adding different concentrations of riboflavin or its inhibitor lumiflavin to the cul-ture medium. Results B. holmesii ABD2 was the pathogen causing bacteremia in the immunocompetent pa-tient. It was deposited under the number of CGMCC 1. 13721 in China General Microbiological Culture Col-lection Center (CGMCC), and the 16S rRNA gene sequences were deposited in National Center for Biotech-nology Information ( NCBI) with the accession number of KT828544. 1. Unrooted tree showed that the B. holmesii strain was highly homologous with B. pertussis. Antibiotic susceptibility test showed that the mini-mum inhibitory concentrations ( MIC) of piperacillin, ceftazidime, cefepime, imipenem, meropenem, cipro-floxacin, levofloxacin, gentamicin, amikacin, erythromycin, tetracycline and polymyxin B against the isolate were low, while the MIC values of cefazolin, cefuroxime, cefoxitin, cefotaxime, aztreonam and trime-thoprim-sulfamethoxazole were high. Riboflavin accelerated the growth of B. holmesii ABD2, while its inhibi-tor lumiflavin had an inhibitory effect. Conclusions As B. holmesii is hard to isolate and identify, limited clinical, microbiological and epidemiological data are available. It is an under-recognized pathogen with a considerable amount of information that remains to be studied.

ABSTRACT

Non-coding RNAs (ncRNAs) are genomic transcripts that do not encode proteins.They are also closely associated with tumor initiation and progression,as they play regulatory roles in gene transcription,post-transcription,and translation.Moreover,ncRNAs may enter circulatory system in the form of microvesicles or exosomes,or in combination with protein.The circulating ncRNAs are stable and widely existed in body fluids such as blood and urine.Certain circulating ncRNAs are differentially expressed in tumors,suggesting that they have potential value as novel tumor biomarkers.This article briefly reviews the progress of circulating microRNA (miRNA),long non-coding RNA (lncRNA) and circular RNA (circRNA) as breast cancer biomarkers,and discusses the clinical value of circulating ncRNA as a novel biomarker for breast cancer diagnosis and prognosis.

ABSTRACT

Objective@#To investigate the clinicopathological characteristics of SMARCA4- deficient thoracic sarcomas.@*Methods@#The clinical features and CT scans of SMARCA4-deficient thoracic sarcomas (n=5) diagnosed at Fudan University Cancer Hospital from December 2016 to October 2018 were reviewed. Hematoxylin-eosin staining, immunohistochemistry and targeted next generation sequencing were performed in available cases along with a literature review.@*Results@#All 5 patients were males with age ranging from 32 to 65 years (average 54 years; median 61 years). Four patients were smokers except one with unknown smoking history. The average maximum diameter of tumor was 5.6 cm. Tumor primary sites included thoracic wall,thoracic cavity,lung and mediastinum. Histologically,tumor cells formed solid sheets or anastomosing islands with brisk mitotic figures accompanying with large areas of necrosis. Three cases focally exhibited rhabdoid morphology and vesicular chromatin. Immunohistochemically, SMARCA4, SMARCA2 and Claudin-4 were negative in all cases and all tumors demonstrated SOX2 and SMARCB1 nuclear positive staining. Among 3 cases analyzed by targeted next generation sequencing, concurrent SMARCA4 and p53 mutation was detected in all three cases. Mutations of STK11, ERBB4, NF2, GNAS, MTOR,MET and FGFR1 amplification were also detected among the three cases. The follow-up information was available in all 5 cases. Two patients died of the tumor. One relapsed multiple times after surgeries but was alive with disease. Two patients received radical excisions without relapse.@*Conclusions@#SMARCA4-deficient thoracic sarcoma is a rare but highly-aggressive tumor with dismal prognosis. The tumor is featured by rhabdoid morphology histologically and distinctive immunohistochemical and molecular phenotype.

ABSTRACT

Objective Nanobacteria are one of the factors for urinary calculi and its exact pathogenic mechanism is not yet clear.The aim of this study was to investigate the role of the CaSR -Claudin-14 regulatory channel in the formation of calculi . Methods Sixty Wistar male rats were equally randomized into a normal control group and nanobacterial group , the former injected via the tail vein with 1.2 mL of 0.9% sodium chloride solution while the latter with 1.2 mL of nanobacterial suspension , both for once.Three of the rats in each group were sacrificed every week in the first 10 weeks after injection.Histopathological examination was performed every week to evaluate the stone formation in the kidneys of the rats , and the expressions of the CaSR and Claudin -14 proteins were determined by immunohistochemistry. Results From the 1st to the 10th week after injection, crystal particles were observed in the rat kidneys of the nanobacterial group, but not in the normal controls (52.4% vs 0%, P<0.01).The expressions of CaSR and Claudin -14 showed no statistically significant differences between the nanobacterial and control groups in the first 3 weeks (P>0.05) but both gradually in-creased in the former group from the 4th to the 10th week as compared with the latter, mainly in membrane of the renal tubular epithelial cells. Conclusion The increased activity of the CaSR -Claudin-14 regulatory channel may play an important role in the formation of nanobacterial renal stone .
