Application of the ArcherQA three-dimensional dose verification system in intensity-modulated radiotherapy plans for nasopharyngeal carcinoma / 中华放射医学与防护杂志

Objective:To investigate the feasibility of applying the ArcherQA three-dimensional (3D) dosimetric verification system in intensity-modulated radiotherapy (IMRT) plans for nasopharyngeal carcinoma (NPC).Methods:A retrospective analysis was conducted for 105 NPC patients′ IMRT plans developed using the Eclipse treatment planning system (TPS). Dose verification was conducted using the ArcherQA system and through portal dosimetry (PD). Moreover, this study compared γ passing rates (criteria: 3 mm/3%, TH = 10%) between ArcherQA and PD and the doses delivered to the target volume ( Dmean, D90%) and organs at risk (OARs) ( Dmean) between ArcherQA and TPS, and analyzed the 3D γ passing rates of each organ at risk calculated by ArcherQA. Results:The average 3D γ passing rate calculated by ArcherQA was (99.04±1.01)%, and the average 2D γ passing rate measured by PD was (99.49±0.78)%, with statistically significant differences ( t=-3.35, P< 0.05). The dosimetric differences to the target volume between ArcherQA and TPS were as follows: the average difference in Dmean to the gross tumor volume (GTV) was (0.57±0.48)%, and the average difference in D90% was (0.65±0.56)%. For the target volume, the average γ passing rate was (97.67±3.43)% for GTV, (97.80±4.35)% for GTVnd-L, (97.82±4.07)% for GTVnd-R, (97.88±2.44)% for CTV1, and (96.64±4.32)% for CTV2. The mean dose difference of each target volume was CTV1 (0.57±0.46)%, GTVnd-L (0.85±0.55)%, GTVnd-R (0.73±0.55)%, and CTV2 (0.88±0.52)%. For OARs, the mean γ passing rate was (99.93±0.22)% for the brainstem, (99.17±2.82)% for the optic chiasm, (100±0)% for the lens, (99.56±1.05)% for the spinal cord, (99.00±2.06)% for the thyroid, and (87.86±10.42)% for the trachea. Statistically significant differences in the average doses to OARs were observed ( t=-14.62 to 4.82, P<0.05), except for those to the left optic nerve, the right hippocampus, and the right parotid gland. Conclusions:Based on the high-performance GPU platform and the Monte Carlo dose algorithm, ArcherQA can provide accurate 3D dose distribution and 3D γ passing rates inside patients according to CT images and provide the dose volume histogram (DVH) of various regions of interest (ROIs). Therefore, the ArcherQA three-dimensional dose verification system can be applied to IMRT plans for NPC. Moreover, it is inducive to improve the treatment efficiency since it does not occupy the accelerator operation time.

There were 28 children with influenza A and 12 with influenza B. All children initially had fever, and the interval between fever and symptoms of neurological onset was 24 hours (0-120 hours). The most-common symptom of neurological onset was seizures(32 cases), among which 17 patients showed continuous seizures.All children presented encephalopathy at varying degrees, including 33 cases in coma and 7 in drowsiness or cognitive decline.Thirty cases developed central respiratory failure and received mechanical ventilation.Examination results showed 30 cases had elevated aspartate transaminase (AST), 18 cases had elevated alanine transaminase (ALT), 14 cases had elevated creatinine, 31 cases had elevated lactate dehydrogenase, 16 cases had elevated blood glucose and 1 case had significantly lowered blood glucose.Blood ammonia testing was performed in 38 children and 9 cases had elevated level.The whole exon sequencing in 6 cases showed de novo heterozygous mutation of the SCN1A gene in 1 case, and heterozygous mutation of the ATP1A2 gene inherited from the mother in another case.Lumbar puncture was performed in 35 cases, and all of them had a normal range of cerebrospinal fluid leukocyte counts, while 12 cases had elevated cerebrospinal fluid proteins.Abnormal image findings were examined in 33 cases and the acute necrotizing encephalopathy was the most common one (14 cases). All children received Peramivir or Oseltamivir after admission.A total of 28 cases were treated with glucocorticoids, and 29 cases were treated with immunoglobulin.Seventeen cases died, 9 cases had disability at varying degrees, and 14 cases recovered to the baseline.Patients were divided into good prognosis group and poor prognosis group.(1) Patients in good prognosis group presented significantly shorter interval between fever and first neurological symptoms[(22.7±12.2) h vs.(38.6± 30.9) h], higher Glasgow score on admission[(7.6±2.5) points vs.(4.5 ± 1.6) points], lower ALT [15.6 (9.0-1 631.5) U/L vs.140.2 (12.3-3 232.4) U/L] and lower AST [47.6 (25.4-1 721.3) U/L vs.251.8 (21.7-4 991.6) U/L] than those in poor prognosis group (all P<0.05). (2) Glucocorticoids were applied to 17 and 11 cases in good prognosis group and poor prognosis group, while immunoglobulins were applied to 17 and 12 cases, respectively ( P>0.05). (3) Patients were further classified into cytokine storm group, excitotoxicity group and unclassifiable group according to clinical imaging findings.The Glasgow score [ (4.6±1.7) points vs.(7.6±2.2) point vs.(7.3±2.8) points] and median modified Rankin Scale score (6.0 points vs.1.5 points vs.0) were significantly different among 3 groups (all P<0.01). Conclusions:Influenza associated encephalopathy is common in infants and young children.Fever, convulsions and rapidly progressing disturbance of consciousness are the most common clinical manifestations.Acute necrotizing encephalopathy is the most common subtype of clinical imaging syndrome.Acute onset and rapid progression predict the poor prognosis of influenza associated encephalopathy.

Recent advances of traditional Chinese medicine on the prevention and treatment of COVID-19 / 中国天然药物

Coronavirus disease-2019 (COVID-19) is a new highly infectious disease caused by a novel coronavirus. Recently, the number of new cases infected pneumonia in the world continues to increase, which has aroused great concern from the international community. At present, there are no small-molecule specific anti-viral drugs for the treatment. The high mortality rate seriously threatens human health. Traditional Chinese medicine (TCM) is a unique health resource in China. The combination of TCM and Western medicine has played a positive and important role in combating COVID-19 in China. In this review, through literature mining and analysis, it was found that TCM has the potential to prevent and treat the COVID-19. Then, the network pharmacological studies demonstrated that TCM played roles of anti-virus, anti-inflammation and immunoregulation in the management of COVID-19 via multiple components acting on multiple targets and multiple pathways. Finally, clinical researches also confirmed the beneficial effects of TCM on the treatment of patients. This review may provide meaningful and useful information on further drug development of COVID-19 and other viral infectious diseases.

Clinical effect of tacrolimus in the treatment of myasthenia gravis in children / 中国当代儿科杂志

OBJECTIVE@#To evaluate the efficacy and safety of tacrolimus in the treatment of children with myasthenia gravis (MG).@*METHODS@#A total of 28 children with MG were treated with tacrolimus. MG-Activities of Daily Living (MG-ADL) scale was used to assess clinical outcome and safety after 1, 3, 6, 9, and 12 months of treatment.@*RESULTS@#After tacrolimus treatment, the MG-ADL score at 1, 3, 6, 9 and 12 months was lower than that at baseline (P<0.05), and the MG-ADL score showed a gradually decreasing trend. The response rates to tacrolimus treatment at 1, 3, 6, 9, and 12 months were 59%, 81%, 84%, 88%, and 88% respectively. At 6, 9, 12, and 18 months of treatment, 4, 13, 14, and 15 children respectively were withdrawn from prednisone. No recurrence was observed during treatment. Major adverse reactions/events were asymptomatic reduction in blood magnesium in 5 children and positive urine occult blood in 1 child, which turned negative without special treatment, and tacrolimus was not stopped due to such adverse reactions/events. One child was withdrawn from tacrolimus due to recurrent vomiting. According to CYP3A5 genotypes, all of the patients were divided into two groups: slow metabolic type (n=19) and non-slow metabolic type (fast metabolic type + intermediate type; n=9). The non-slow metabolism group received a higher dose of tacrolimus, but had a lower trough concentration of tacrolimus than the slow metabolism group (P<0.05). The slow metabolism group had a higher response rates to tacrolimus treatment than the non-slow metabolism group (P<0.05).@*CONCLUSIONS@#Tacrolimus appears to be effective and safe in the treatment of children with MG and is thus an option for immunosuppressive therapy. CYP3A5 genotyping has a certain guiding significance for determining the dosage of tacrolimus.

Single-balloon Enteroscopy for Diagnosis of Meckel Diverticulum in Adults / 胃肠病学

Background: Meckel diverticulum is one of the most common congenital malformations of the gastrointestinal tract. It is relatively rare in adults and is difficult to make a preoperative diagnosis. Aims: To analyze the clinical characteristics of Meckel diverticulum in adults and to investigate the diagnostic value of single-balloon enteroscopy for adult Meckel diverticulum. Methods: A retrospective study was performed in patients diagnosed as adult Meckel diverticulum by single-balloon enteroscopy at Renji Hospital, School of Medicine, Shanghai Jiao Tong University from Apr. 2011 to Jan. 2019. Results: A total of 30 adult Meckel diverticulum patients were enrolled. Of them, 26 were male and 4 were female with a mean age of (36.1±14.6) years. The mean duration of symptoms ranged from 6 days to 30 years. The prevalence of gastrointestinal bleeding, abdominal pain/diarrhea, and anemia was 73.3% (22/30), 40.0% (12/30), and 50.0% (15/30), respectively. All the diverticula were detected by retrograde single-balloon enteroscopy. The mean distance of diverticulum from the ileocecal valve was (98.7±29.5) cm, and the size of diverticulum opening was 3.25 cm on average. Ulcer was found in 11 cases. Sixteen cases underwent surgical resection, and 12.5% and 18.8% of them were proved to contain ectopic gastric mucosa and ectopic pancreas, respectively. The diagnostic yield of capsule endoscopy and imaging modalities were relatively low (39.1% and 20.7%, respectively). Conclusions: Single-balloon enteroscopy has a high diagnostic value for Meckel diverticulum in adults and may provide guidance for clinical treatment. For adults suspected of Meckel diverticulum, retrograde single-balloon enteroscopy is recommended.

Diagnosis and treatment of 40 cases of gastritis cystica profunda / 中华消化内镜杂志

Objective To investigate the clinical,endoscopic and pathological features of gastritis cystica profunda (GCP).Methods A total of 40 patients with GCP confirmed by pathology who received endoscopic or surgical treatment at Renji Hospital,School of Medicine,Shanghai Jiaotong University from May 2013 to May 2018,were included in the retrospective analysis.The clinical data such as population composition,clinical manifestations,endoscopic findings and pathological results were summarized and analyzed.Results Among the 40 patients were predominantly males (75.0％,30/40),and the mean age of onset was 61.2 years.The most common sites were cardia (32.5％,13/40) and gastric antrum (30.0％,12/40).The clinical symptoms of the patients were atypical and it was difficult to diagnose GCP with routine endoscopy examination.The endoscopic findings were mostly type 0-Ⅱ (50.0％,20/40).GCP with neoplastic lesions accounted for 55％ (22/40).Unconditional logistic regression analysis showed that male (P =0.013,OR =31.093,95％ CI:2.079-464.976) and Helicobacter pylori infection (P =0.041,OR =10.225,95％ CI:1.096-95.411) were risk factors for GCP with neoplastic lesions.Conclusion GCP commonly occurs in middle-aged and elderly men,and varies in different manifestations under white light endoscopy.GCP is not a benign lesion,but can also coexist with neoplastic lesions,which are mostly differentiated intramucosal cancer.

Clinical characteristics and follow-up of Hashimoto encephalopathy in children / 临床儿科杂志

Objective To explore the clinical characteristics of Hashimoto encephalopathy (HE) in children. Methods The clinical data of 4 children with HE were analyzed retrospectively. Results All the 4 cases were school-age children and 3 of them were girls. They were physically healthy before onset. The main clinical manifestations were epileptic seizures in 3 cases, mental symptoms in 2 cases, disturbance of consciousness in 2 cases, stroke like symptoms in 1 case, decreased memory and decreased sleep in 1 case. Electroencephalogram showed that the background activity was decreased in 4 cases, and MRI showed abnormal in 3 cases. Serum thyroid antibodies were significantly increased in 4 cases, and were returned to normal in 2 cases when clinical symptoms disappeared, while they were significantly reduced, but not completely back to normal in another 2 cases. Only one out of 4 cases had abnormal thyroid function. All the 4 cases responded well to corticosteroid therapy. One of them relapsed after discontinuation of the therapy, but it was still effective when the therapy was reassumed. Conclusions HE is rare in children. When there are manifestations of unknown cause, such as epileptic seizures, mental disorders, cognitive impairment, movement disorders and disturbance of consciousness, HE should be considered. In addition, the increase of serum thyroid antibody should be considered as a necessary condition for diagnosis.

Clinical observation of fluorescence endoscopy in medical diagnosis / 中国医疗器械杂志

It's difficult to diagnose precancerous lesion and early cancer for a long time, because both of them haven't typical morphological characteristics. As a novel diagnostic modality, fluorescence endoscopy can accurately reflect minimal changes in human's tissue, thus making a meaningful progress for cancer diagnosing. 200 patients were examined by fluorescence endoscopy to evaluate the diagnostic value. The overall accuracy, sensitivity and specificity for detecting malignant gastrointestinal tumor was 94.0%, 94.6% and 93.5%, respectively. Thus, fluorescence endoscopy can be used to diagnose malignant gastrointestinal tumors with high validity and reliability, and is advantageous over conventional white light endoscopy especially in detecting the atypical and suspicious lesions. Furthermore, fluorescence endoscopy can also guide target biopsy, is significant to improve the early cancer detection rate, has a broad development prospect.
