ABSTRACT

OBJECTIVE@#To evaluate the efficacy and safety of Jianpi Jieyu Decoction (JJD) for treating patients with mild-to-moderate depression of Xin (Heart)-Pi (Spleen) deficiency (XPD) syndrome.@*METHODS@#In this multi-center, randomized, controlled study, 140 patients with mild-to-moderate depression of XPD syndrome were included from Xiyuan Hospital of China Academy of Chinese Medical Sciences and Botou Hospital of Traditional Chinese Medicine from December 2017 to December 2019. They were randomly divided into JJD group and paroxetine group by using a random number table, with 70 cases in each group. The patients in the JJD group were given JJD one dose per day (twice daily at morning and evening, 100 mL each time), and the patients in the paroxetine group were given paroxetine (10 mg/d in week 1; 20 mg/d in weeks 2-6), both orally administration for a total of 6 weeks. The primary outcome was the change of 17-item Hamilton Depression Rating Scale (HAMD-17) score at week 6 from baseline. The secondary outcomes included the Hamilton Anxiety Scale (HAMA) score, Traditional Chinese Medicine Symptom Scale (TCMSS), and Clinlcal Global Impression (CGI) scores at the 2nd, 4th, and 6th weekends of treatment, HAMD-17 response (defined as a reduction in score of >50%) and HAMD-17 remission (defined as a score of ⩽7) at the end of the 6th week of treatment. Adverse events (AEs) were also recorded.@*RESULTS@#From baseline to week 6, the HAMD-17 scores decreased 10.2 ± 4.0 and 9.1 ± 4.9 points in the JJD and paroxetine groups, respectively (P=0.689). The HAMD-17 response occurred in 60% of patients in the JJD group and in 50% of those in the paroxetine group (P=0.292); HAMD-17 remission occurred in 45.7% and 30% of patients, respectively (P=0.128). The differences of CGI scores at the 6th week were not statistically significant (P>0.05). There were significant differences in HAMD-17 scores between the two groups at 2nd and 4th week (P=0.001 and P=0.014). The HAMA scores declined 8.1 ± 3.0 and 6.9 ± 4.3 points from baseline to week 6 in the JJD and paroxetine groups, respectively (P=0.905 between groups). At 4th week of treatment, there was a significant difference in HAMA between the two groups (P=0.037). TCMSS decreased 11.4 ± 5.1, and 10.1 ± 6.8 points in the JJD and paroxetine groups, respectively (P=0.080 between groups). At the 6th week, the incidence of AEs in the JJD group was significantly lower than that in the paroxetine group (7.14% vs. 22.86%, P<0.05).@*CONCLUSION@#Compared with paroxetine, JJD was associated with a significantly lower incidence of AEs in patients with mild-to-moderate depression of XPD syndrome, with no difference in efficacy at 6 weeks.

ABSTRACT

Objective@#To investigate the prevalence of scoliosis among primary and middle school students in Jiaxing City, Zhejiang Province, so as to provide insights into scoliosis control among children and adolescents. @*Methods@#Grade 4 to 6 primary school students and grade 1 to 3 junior high school students were recruited using a stratified cluster sampling method in Jiaxing City in 2019. Participants' demographic characteristics, dietary habits and nutritional status, physical activity, learning environments, reading and writing habits were collected using questionnaires. Scoliosis was screened through general examinations, forward bend test and scoliometer, and scoliosis was diagnosed with whole-spine X-ray scans in an erect position. The prevalence of scoliosis was descriptively analyzed among primary and middle school students.@*Results@#A total of 8 026 primary and middle school students were included, 7 304 valid questionnaires were recovered, with an effective recovery rate of 91.00%. The respondents included 3 667 primary school students (50.21%) and 3 637 junior high school students (49.79%), and included 3 776 boys (51.70%) and 3 528 girls (48.30%). There were 659 participants with initial screening positive for scoliosis (9.02%), and the percentages of positive initial screening of thoracic, thoracolumbar and lumbar scoliosis were 2.93%, 4.56% and 4.56%, respectively. A higher percentage of positive initial screening of scoliosis was diagnosed among participants living in Pinghu City (10.45%), junior high school students (11.74%), girls (11.96%), students with a medical history of anemia (22.44%), students with less than 3 days of moderate-intensity physical activity in the past week (9.46%), students with less than 3 days of walking duration of over 10 minutes in the past week (10.18%), students with daily sitting duration of 5 hours and more in the past week (10.74%), students with their class seats exchanged every semester or month (10.28%), students with daily reading and writing duration of 3 hours and more after school (10.93%) and students with less than 10 cm distance from the chest at reading or writing to the edge of the table (9.67%) (all P<0.05). A total of 218 students received whole-spine X-ray scans in an erect position, 132 participants were definitively diagnosed as scoliosis (60.55%), and the estimated prevalence of scoliosis was 5.46%.@*Conclusion@#The percentage of positive initial screening of scoliosis was 9.02% among primary and middle school students in Jiaxing City. Gender, stage of learning, nutritional status, exercise frequency and habits of reading and writing may be factors affecting the development of scoliosis.

ABSTRACT

As a member of the dibenzyl isoquinoline alkaloid family, cepharathine is an alkaloid from the traditional Chinese medicine cepharathine, which is mainly used for treatment of leukopenia and other diseases. Recent studies of the inhibitory effect of cepharathine against SARS-CoV-2 have attracted widespread attention and aroused heated discussion. As the original discoverer of the anti-SARS-CoV-2 activity of cepharanthine, here we briefly summarize the discovery of cepharanthine and review important progress in relevant studies concerning the discovery and validation of anti-SARS-CoV-2 activity of cepharathine, its antiviral mechanisms and clinical trials of its applications in COVID-19 therapy.

ABSTRACT

A 15-year-old female was referred to the hospital with intermittent fever, where multiple systemic abnormalities were found, such as splenomegaly, secondary hypersplenism, retinitis pigmentosa, and ectodermal dysplasia. Medical history revealed that she had suffered recurrent respiratory infections, blurred vision at night, and dysplasia of teeth and nail beds since childhood. Then she was suspected to be experiencing ROSAH syndrome, a rare disease newly recognized in recent years, which was finally confirmed by gene sequencing results. During a course of treatment with tumor necrosis factor inhibitors, recurrent fever with elevated inflammatory markers reappeared, and the child developed headaches. To guide the comprehensive treatment and improve the patient's quality of life, the multidisciplinary team in Peking Union Medical College Hospital discussed together and directed the following treatment.

ABSTRACT

Some kinds of chronic sialadenitis were recognized during the recent years. They have specific pathogenesis, clinical and histopathologic appearances, and require specific treatment. IgG4-related sialadenitis (IgG4-RS) is one of the immune-mediated diseases, characterized by tumefactive lesions. The incidence of IgG4-RS obviously increased during the past 30 years. The study on the potential relationship between occupational exposure to chemical substances and the incidence of IgG4-RS showed that subjects with occupational exposure to agents known to cause IgG4-RD had an increased risk for IgG4-RS. Surgical excision of involved SMG could not control the disease progression, which is not recommended for treatment of IgG4-RS. The combination of glucocorticoid and steroid-sparing agents is effective for treating IgG4-RS, and restores salivary gland function. Radioiodine induced sialadenitis (RAIS) is one of the common complications of postoperative adjuvant treatment of differentiated thyroid cancer by 131I. The incidence of the disease is related to radiation dosage. Clinically, the patients suffered from swelling and tenderness in the buccal or submandibular regions, especially during the mealtime. Imaging appearances are similar to those of chronic obstructive sialadenitis. Conservative managements, such as gland massage, sialagogues, are the mainstream methods in the treatment of RAIS. Sialendoscopy is feasible for RAIS, but not as effective as conventional obstructive sialadenitis (COS). Therefore the prevention of RAIS is crucial. Eosinophilic sialodochitis (ES) is a new type of chronic inflammatory disease of the salivary gland related to allergy. It has characteristics of swelling of multiple major salivary glands, strip-like gelatinous plugs discharged from the duct orifice of the gland, elevated level of serum IgE and eosinophils in peripheral blood, infiltration of eosinophils and IgE positive plasma cells in the tissues, allergic history, increased expression of allergy-related cytokines, such as IL-4, IL-5, IL-13, and eotaxin, which suggest allergic reactions as a potential pathogenesis of the disease. The clinical, laboratory, histological, and immunohistochemical characteristics of ES are significantly different from conventional obstructive sialadenitis (COS). Therefore, it is suitable to separate ES from COS. Conservative managements, such as self-maintenance therapy and anti- allergic modality are the choices of treatment for ES. Based on the results of our comprehensive studies a new classification of chronic sialadenitis is suggested.

ABSTRACT

Objective:To summarize the clinical characteristics of adenovirus (HAdVs) pneumonia in children.Methods:The clinical manifestations, laboratory results, imaging features and treatment courses of 541 children with HAdVs pneumonia treated in Shenzhen Children′s Hospital from January 2017 to August 2019 were retrospectively studied.Results:The number of children diagnosed with HAdVs pneumonia increased year by year.A total of 541 patients were included in this study (214 females and 327 males, median age 31 months). The majority of patients (89.3%, 483/541 cases) were less than 6 years of age.Cough (98.3%, 532/541 cases) was the most common symptom, followed by fever (93.7%, 507/541 cases), tachypnea (36.6%, 198/541 cases) and wheeting (32.5%, 176/541 cases). Thirteen point three percent patients (72/541 cases) had existing primary diseases.Severe HAdVs pneumonia was observed in 33.8% of patients (183/541 cases), the most common intrapulmonary complication were pleural effusion(18.6%, 101/541 cases) and respiratory failure (7.0%, 38/541 cases). In co-infection cases, 46.9% of the patients (254/541 cases) suffered from co-infection with mycoplasma pneumoniae, 21.6% of the patients (117/541 cases) suffered from bacterial co-infection.Ninety-eight point five percent of the patients (533/541 cases) were cured, and 1.5% of the patients (8/541 cases) died or discharged voluntarily.Convulsions [ P=0.026, OR=7.312 (95% CI: 1.267-42.191)] and bacterial co-infections [ P=0.030, OR=2.724 (95% CI: 1.101-6.741)] were independently correlated with the occurrence of severe HAdVs pneumonia. Conclusions:Pre-school aged children are at higher risks of developing HAdVs pneumonia.The majority of patients presents with fever and cough as primary manifestations.Tachypnea and wheezing are also common clinical features of HAdVs pneumonia patients.Approximately a third of children with HAdVs pneumonia may develop into severe pneumonia.The presentation of convulsion and the exis-tence of bacterial co-infections may help to predict the development of severe HAdVs pneumonia in pediatric patients.

ABSTRACT

Objective:To study the soil physical and chemical properties, microorganisms, and metabolites in different culture environments of <italic>Gastrodia elata</italic>, so as to provide scientific basis for subsequent cultivation of <italic>G. elata</italic> in multiple environments. Method:The tubersphere soil of <italic>G. elata</italic> cultured in different environments was collected for analyzing the soil nutrients, microbial numbers, and metabolite differences using the agrochemical method, plate-count method, and gas chromatography-time-of-flight mass spectrometry (GC-TOF-MS)-based non-targeted metabonomic approach. Result:The analysis of soil physical and chemical properties revealed the highest soil moisture, pH, available potassium, and available phosphorus in the spinney and the highest electrical conductivity, total nitrogen, alkali-hydrolyzable nitrogen, and organic matter in the pinewood. As demonstrated by the quantitative analysis of soil microorganisms, the cultivable microorganisms were bacteria, actinomycetes, and fungi, with the bacterial population and total microbial biomass in the spinney and the number of fungi and actinomycetes in the barren slope detected to be the largest. The ratio of bacteria to fungi (B/F value) in the pinewood was the highest, while that in the barren slope was the lowest. The results of metabonomic research demonstrated that the compositions and quantities of soil metabolites in the spinney (Z group), pinewood (S group), and barren slope (HD group) varied. Through comparisons between S and Z groups, between HD and Z groups, as well as between HD and S groups by orthogonal partial least squares discriminant analysis (OPLS-DA), 18, 35, and 24 differential metabolites were separately screened out, and the Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis yielded 5, 9, and 13 metabolic pathways. There existed a significant causal relationship of the soil physical and chemical properties and microbial numbers with the metabolites. Conclusion:The soil physical and chemical properties, microbial numbers, and metabolite changes differed significantly in different culture environments of <italic>G. elata</italic>, which were sorted by the suitability in a descending order as follows: spinney > pinewood >barren slope. The soil physical and chemical properties and microbial numbers are the crucial factors driving changes in soil metabolites, suggesting that regulating the soil physical and chemical characteristics and microbial characteristics in the culture environment is an important mechanism for maintaining the <italic>G. elata</italic>-soil-microbial symbiotic system.

ABSTRACT

OBJECTIVE@#To investigate the value of optic disc retinal nerve fiber layer (RNFL) thickness in the diagnosis of diabetic peripheral neuropathy (DPN).@*METHODS@#Ninety patients with type 2 diabetes, including 60 patients without DPN (NDPN group) and 30 patients with DPN (DPN group), and 30 healthy participants (normal group) were enrolled. Optical coherence tomography (OCT) was used to measure the four quadrants and the overall average RNFL thickness of the optic disc. The receiver operator characteristic curve was drawn and the area under the curve (AUC) was calculated to evaluate the diagnostic value of RNFL thickness in the optic disc area for DPN.@*RESULTS@#The RNFL thickness of the DPN group was thinner than those of the normal and NDPN groups in the overall average ((101.07± 12.40) µm vs. (111.07±6.99) µm and (109.25±6.90) µm), superior quadrant ((123.00±19.04) µm vs. (138.93±14.16) µm and (134.47±14.34) µm), and inferior quadrant ((129.37±17.50) µm vs. (143.60±12.22) µm and (144.48±14.10) µm), and the differences were statistically significant. The diagnostic efficiencies of the overall average, superior quadrant, and inferior quadrant RNFL thicknesses, and a combined index of superior and inferior quadrant RNFL thicknesses were similar, and the AUCs were 0.739 (95% confidence interval (CI) 0.635-0.826), 0.683 (95% CI 0.576-0.778), 0.755 (95% CI 0.652-0.840), and 0.773 (95% CI 0.672-0.854), respectively. The diagnostic sensitivity of RNFL thickness in the superior quadrant reached 93.33%.@*CONCLUSIONS@#The thickness of the RNFL in the optic disc can be used as a diagnostic method for DPN.

ABSTRACT

Standardized residency training is the only way for medical students to grow into qualified doctors. Since the implementation of pediatric standardized residency training nationwide in 2014,the training has been progressing smoothly and has made remarkable achievements. In order to further adapt to the status of residential training,meet the needs of pediatric training nationwide and improve the quality of pediatric training,the Pediatric Professional Committee organized experts to brainstorm and revise the two criteria, "Pediatric Criteria for Standardized Residency Training Base" and "Pediatric Criteria for Standardized Residency Training Contents". The revision of these two criteria follows the principles of continuity,accessibility,advancement and consistency. Revision was focused on lowering the scale of the base,proposing the concept of professional group,making rotation of specialty flexible,and strengthening stratified training. We hope to improve the capability of base to improve the comprehensive ability of residential students without increasing the bed size. It is believed that the pediatric standardized residency training system will provide a solid foundation for the pediatric training through providing good policy guidance,support,and medical and educational cooperation.

ABSTRACT

Objective@#To understand the situation and characteristics of out-patient utilization of urban and rural pneumoconiosis patients in Jiangsu province, and to provide a reference for the formulation of relevant policies.@*Methods@#Using a questionnaire on patients with pneumoconiosis and their influencing factors, 120 patients with pneumoconiosis were randomly selected in Nanjing, Wuxi, Suzhou, Yancheng Vocational Defense Institute or CDC. The rate of outpatients with pneumoconiosis in urban and rural areas and the choice of out-patient hospitals were analyzed.@*Results@#Of the 75 patients with severe pneumoconi-related symptoms such as chest tightness and dyspnea in the first two weeks of the survey, 36 (48.0%) lived in cities and 39 (52.0%) lived in rural areas. Patients with pneumoconiosis who live in urban and rural areas have different aggravating conditions within two weeks. Two weeks of aggravated symptoms in outpatient consultations accounted for36 (48.0%) . Of the 36 patients who used outpatient treatment, rural residents mainly chose 8 people from a hospital and a township health hospital, accounting for 34.8%, while 10 people from urban residents chose a nursing home or nursing home, accounting for 40.0%. The main reason why urban and rural pneumoconiosis patients did not go to the doctor is "conscious symptoms are lighter" and "feel that the doctor is useless."@*Conclusion@#The rate of outpatients with pneumoconiosis in Jiangsu province within two weeks is lower than that of ordinary elderly residents. There may be differences in treatment behavior patterns of urban and rural pneumoconiosis patients.Economic factors have a certain influence on the outpatient treatment behavior of pneumoconiosis patients. The recognition of outpatient service is the main factor affecting the outpatient treatment of pneumoconiosis patients. It is very important to popularize the knowledge of pneumoconiosis and do a good job in propaganda of occupational diseases and health education for pneumoconiosis patients. Focusing on the outpatient treatment of pneumoconiosis patients and making targeted medical policies is very important to standardize and improve the rehabilitation of pneumoconiosis patients.

ABSTRACT

Objective@#To study the main factors that influencing Pneumoconiosis patients' healthcare seeking behaviors.@*Methods@#Conducting a descriptive analysis to analyze the relationship between the annual hospitalization rate and social security status (medical insurance, location of medical insurance, proportion of insurance used for reimbursement of pneumoconiosis, whether there is employment injury insurance at work, whether to apply for compensation after diagnosing pneumoconiosis, whether they receive social assistance and a minimum allowance) , social relationship status of patients (whether there is pneumoconiosis in the family or relatives, whether there is a pneumoconiosis in a friend or a colleague, and whether or not he/she has received financial assistance) , life quality of patients (subjective feelings) and living standard of patients (dietary level) based on data acquired from 120 pneumoconiosis patients.@*Results@#The results of single factor analysis reveal that the location of medical insurance, the proportion of insurance for reimbursement of pneumoconiosis, whether there is employment injury insurance at work, whether to apply for compensation after diagnosing pneumoconiosis are statistically significant in pneumoconiosis patients' hospital utilization ratio (P<0.05) . The place where medical insurance is located is the current place of residence, the reimbursement ratio of medical insurance for pneumoconiosis is listed as 50%-70%, the work unit has medical insurance, those who have not applied for compensation for pneumoconiosis have a higher utilization rate of hospitalization services. The annual hospitalization rate was 73.3%, 80.0%, 60.6%, 63.0%, respectively.@*Conclusion@#The location of patient medical insurance, the proportion of insurance used for reimbursement of pneumoconiosis, whether there is employment injury insurance at work, and whether to apply for compensation after pneumoconiosis are the influencing factors of the patients' annual hospitalization rate.

ABSTRACT

Immunoglobulin G4-related sialadenitis (IgG4-RS) is a newly recognized immune-mediated disease and one of immunoglobulin G4-related diseases (IgG4-RD). Our multidisciplinary research group investigated the clinicopathological characteristics and diagnosis of IgG4-RS during the past 10 years. Clinically, it showed multiple bilateral enlargement of major salivary glands (including sublingual and accessory parotid glands) and lacrimal glands. The comorbid diseases of head and neck region including rhinosinusitis, allergic rhinitis, and lymphadenopathy were commonly seen, which could occur more early than enlargement of major salivary glands. Internal organ involvements, such as autoimmune pancreatitis, sclerosing cholangitis, and interstitial pneumonia could also be seen. Thirty-five (38.5%) patients had the symptom of xerostomia. Saliva flow at rest was lower than normal. Secretory function was reduced more severely in the submandibular glands than in the parotid glands. Serum levels of IgG4 were elevated in almost all the cases and the majority of the patients had increased IgE levels. CT, ultrasonography, and sialography showed their imaging characteristics. Histologically it showed marked lymphoplasmacytic inflammation, large irregular lymphoid follicles with expanded germinal centers, prominent cellular interlobular fibrosis, eosinophil infiltration, and obliterative phlebitis. Their immunohistological examination showed marked IgG-positive and IgG4-positive plasma cell infiltration and high IgG4/IgG ratio. The disease could be divided into three stages according to severity of glandular fibrosis. The serum IgG4 level was higher and the saliva secretion lower as glandular fibrosis increased. IgG4-RS should be differentiated from other diseases with enlargement of major salivary gland and lacrimal gland, such as primary Sjögren syndrome, chronic obstructive submandibular sialadenitis, and eosinophilic hyperplastic lymphogranuloma.

ABSTRACT

Nowadays, the cultivation of traditional Chinese medicinal materials is faced with the problems of pesticides illegal uses and pesticides residues. In the early period of eco-agriculture of Chinese materia medica, the uses of pesticides in special time is still inevitable. However, the registration of pesticides for Chinese medicinal materials now is far from enough to meet demand. So it is necessary to publish policies to expand the pesticides registration for Chinese medicinal materials. We collected and analyzed the data of pesticide registration for Chinese medicinal materials, the results showed that till March 2018, there were 10 kinds of Chinese medicinal materials, 91 pesticide products and 46 kinds of pesticide ingredients registered. Based on the current status of the pesticide management in China and the experience of the registration pesticide for minor crops in countries around the world, we point out that the pesticide registration for Chinese medicinal materials should be carried out in the form of minor crops and some specific methods are also provided in this paper.

ABSTRACT

Objective To monitor the environmental contamination with avian influenza virus (AIV) in Henan Province. Methods Environmental samples were collected every month from seven moni-toring sites in Henan from 2013 to 2017. Real-time RT-PCR method was performed to detect the nucleic acid of influenza A (Flu A), H5, H7 and H9 viruses in poultry environmental samples. Results A total of 2538 environmental samples were collected and 202 (7. 96% ) of them were positive for Flu A nucleic acid, including 16 positive for H5 (0. 63% ), eight positive for H7 (0. 32% ) and 161 positive for H9 (6. 34% ). The detection rate of Flu A increased dramatically from 2013 to 2017 except for a small fluctuation in 2015. However, H7 subtype AIV was detected only in 2015 and 2017. The highest detection rate of AIV was in February, followed by that in January. Among different environments, the highest detection rate of Flu A was in live poultry market, which was 13. 69% , followed by that in poultry slaughtering plant (2. 58% ) and poultry farm (0. 58% ). The detection rates of Flu A in swab samples of poultry plucker and cutting board, stool specimens and poultry drinking water were 28. 57% , 13. 76% , 5. 70% and 5. 26% , respectively.Conclusion Contamination of H5 / H7 / H9 AIV did exist in poultry environment in Henan and was getting worse. Increasingly diversified sources and sale channels were the main causes of serious contamination of AIV. In order to effectively prevent and control human infection with AIV, live poultry in areas where human infection with AIV was confirmed should be blocked and banned to be sold to others areas.

ABSTRACT

Objective:To compare the image quality between motion-corrected of phase sensitive inversion recovery SSFP (PSIR SSFP MOCO) sequences and segmented phase sensitivity inversion recovery turbo fast low angel shot PSIR (PSIR segmented turbo Flash) sequences in MRI myocardial enhancement.Methods:A total of 56 patients with PSIR segmented and PSIR SSFP MOCO for myocardial enhancement were retrospectively studied.Subjective quality score (gradel-4),signal to noise ratio (SNR) and relative SNR of normal myocardium,abnormal enhancement of myocardium and left ventricular chamber images were paired and compared between 2 different LGE techniques.Results:Subjective quality scores in PSIR segmented group were as 4 points 28.6%,3 points 41.1%,2 points 28.6%,1 point 1.8% respectively.In PSIR SSFP MOCO group,4 points was 96.4% which was higher than PSIR segmented group,P<0.001,3 points 3.6%,2 points and 1 point were both 0%.The following SNRs were higher in PSIR MOCO SSFP group than PSIR segmented group as in normal myocardium (4.70±3.47) vs (3.64±3.2),P=0.074;in abnormal myocardium (52.58±36.58) vs (27.65±18.47),P<0.001 and in left ventrieular chamber (40.52±33.97) vs (23.14±11.46),P<0.001 respectively.The following relative SNRs were higher in PSIR MOCO SSFP group than PSIR segmented group as in normal to abnormal myocardium (47.46±33.97) vs (23.75±16.68),P<0.001;abnormal myocardium to left ventricular chamber (8.53±17.77) vs (4.54±10.10),P=0.181 and left ventricular chamber to normal myocardium (35.82±25.72) vs (19.49±9.44),P<0.001 respectively.Conclusion:Compared with PSIR segmented sequence,PSIR SSFP MOCO technique can obtain better quality of delay-enhanced myocardial images.

ABSTRACT

Objective:To explore the clinical characteristics of the co-morbidity of vasovagal syncope (VVS) and postural tachycardia syndrome (POTS) with allergic diseases in children.Methods:A retrospective analysis was launched to summarize the clinical data of children with VVS and POTS.They were divided into allergic group and non-allergic group according to the history of allergic diseases.The participants' clinical characteristics were compared between allergic group and non-allergic group using independent sample t test or rank sum test;composition comparisons were completed by Chi-square test.Bi-variate correlation analysis was used to explore the association between eosinophil percentage/count and symptom scores/frequency of syncope episodes.A P value < 0.05 was defined as statistically significant.Results:Sixty-seven children complaining of orthostatic intolerance (43 patients diagnosed as VVS and 24 cases diagnosed as POTS) were enrolled.Totally 21 cases (31%) had allergic diseases,inclu ding allergic rhinitis,atopic eczema,asthma,as well as food allergy.And allergic rhinitis is the most common co-morbidity.There were no significant differences between the two groups in age,gender ratio,height,body weight and basement blood pressure.Compared with the non-allergic group,the allergic group showed later onset age (year) (11 ± 2 vs.9 ± 3,P < 0.05) of orthostatic intolerance and shorter course of the diseases (month) [8.0 (0.1,0.1) vs.24.0 (0.1,144.0),P<0.05].The frequency of syncope episodes in the allergic group among VVS children (times per month) [2.50 (0.08,30.00) vs.O.25 (0.03,5.00),P < 0.05] was much higher than that in the non-allergic group.Additionally,the eosinophil percentage (%) [3.50 (0.70,0.59) vs.1.65 (0.30,6.20),P<0.001] and eosino phil count (×109) [0.18 (0.05,0.71) vs.0.10 (0.02,0.38),P<0.001] were increased in the allergic group.However,there were no remarkable differences in the results of head-up tilt test in children with VVS or in the maximum change of heart rate during standing test in children with POTS were involved.Conclusion:Allergic diseases are common co-morbidities in children with both VVS and POTS.Allergic rhinitis is the most common co-morbidity.Children with co-morbidity of VVS/POTS and allergic diseases had a later onset of symptoms of orthostatic intolerance,and were more likely to be hospitalized for intensive attacks of symptoms during a short period when compared with those without allergic diseases.Children diagnosed as VVS combined with allergic diseases had more frequent episodes of syncope.
