ABSTRACT
Objective:To compare the efficacy of combination therapy on cyclic vomiting syndrome(CVS)in children, and improve the efficacy of CVS treatment in the future.Methods:This study retrospectively analyzed patients′ medical records of CVS, which were admitted to Digestive Department of Beijing Children′s Hospital from 2012 to 2019.The treatment regimen was A(Cyproheptadine+ Doxepin+ Valproate), B(Propranolol+ Cyproheptadine), or C(Propranolol+ Amitriptyline). Meanwhile, the patients should take drugs more than three months.The clinical data of 42 cases were analyzed retrospectively, and the treatment effect after discharge was followed up by telephone until October, 2020.Results:Among the 42 cases, 17 were male and 25 were female, whose mean age of onset was (4.65±3.23) years, and the age of diagnosis was (6.79±3.58) years.The main accompanied symptoms were abdominal pain and upper gastrointestinal bleeding.Forty-two patients were moderate/severe CVS.The regimens A, B and C were observed in 7, 11, and 24 patients, respectively.The age at improvement was(8.17±4.12)years.The course of treatment was(1.37±0.96)years.The age at follow-up was(10.32±4.03)years.During the 1-year follow-up, 35 cases were effective, and the efficiency was 83.3%.Among them, 23 cases had no paroxysmal vomiting and 7 cases had no effect.There was no significant difference in therapy effects among group A, B and C. Between the effective group and non-effective group, there were statistical differences in the personal history of hiatus hernia( P=0.024), the weight at follow-up ( P=0.042), and the course of medication( P=0.020). Conclusion:The combination regimen has a higher effective rate in the treatment of CVS.There was no significant difference among the three regimens in the treatment of CVS.For children with refractory CVS, who can not be treated with combination therapy, individualized therapy should be further developed.
ABSTRACT
Objective:To summarize and analyze the clinical features of food protein-induced enterocolitis syndrome (FPIES).Methods:The medical history and follow-up data of 5 children with FPIES diagnosed in Department of Gastroenterology, Beijing Children′s Hospital of Capital Medical University from July 2018 to September 2019 were collected, and their clinical characteristics were summarized and analyzed.Results:Five children with FPIES were all infants, including 3 females and 2 males.Before the onset of the disease, the cases visited multiple departments and the average number of visits before diagnosis was 3.There were 4 cases of milk protein allergy and 1 case of egg white allergy.The patients had acute vomiting [5 cases (100%)], diarrhea [4 cases (80%)], early shock symptoms [5 cases (100%)], transient fever [2 cases (40%)]. Hematogenous leukocytes were increased in 3 cases (60%), C-reactive protein was increased in 1 case (20%), faecal leukocytes(+ )[2 cases (40%)], occult blood (+ ) [1 case (20%)]. Four cases were tested for food allergen specific IgE, of which 2 cases (40%) were positive for milk protein.After avoiding allergens, 3 patients (60%) needed intravenous rehydration treatment and 2 cases (40%) received oral rehydration treatment.The above 5 cases recovered quickly.Three patients (60%) used antibiotics.Four cases (80%) of the first-degree relatives of FPIES had a clear history of allergy.Families of children with FPIES had low awareness of the disease before the diagnosis was made, and the allergens were strictly avoided according to the doctor′s instructions after the diagnosis was made.Similar allergic reactions did not occur again, and complementary foods were gradua-lly added under the guidance of the doctor.Two patients had multiple food allergies.The body weight and length of 2 children with growth retardation were catching up with each other.Conclusions:FPIES is a serious food allergy related gastrointestinal disease which is easy to be misdiagnosed clinically.The diagnosis requires a combination of the family and personal allergy history, diet records, the characteristic performance of disease onset, the effect of diet avoi-dance and the necessary differential diagnosis.The long-term management and monitoring after diagnosis is also very important.
ABSTRACT
Objective:To evaluate the clinical efficacy and safety of Infliximab (IFX) in pediatric Crohn′s disease (CD).Methods:The efficacy of IFX therapy in 30 patients suffering from active CD who were not completely improved with traditional medicine and enteral nutrition or had intolerance to the medicine in Beijing Children′s Hospital Affiliated to Capital Medical University from December 2014 to December 2019 were retrospectively analyzed.Pediatric Crohn′s Disease Activity Index (PCDAI), blood biochemistry indices, mucosal healing, nutritional status, and adverse reactions were compared and evaluated.Results:Thirty active CD cases, with 18 males and 12 females, were enrolled, and the average age was (8.63±4.76) years old.Three cases who didn′t complete 3 times of IFX injection and 1 case who lost to be followed up were excluded.A total of 26 cases of CD in active period were enrolled in this study on efficacy.The clinical remission and response rate of 26 cases were 61.5% and 84.6%, respectively, at 14-week of IFX therapy.The clinical remission and response rate of 21 cases were 71.4% and 85.7%, respectively, at 30-week.The clinical remission and response rate of 15 cases were 86.7% and 93.3%, respectively, at 54-week.At week 14 th, PCDAI score [(9.56±8.05) scores vs.(29.02±10.86) scores] decreased compared with before treatment ( t=7.339, P<0.05). The levels of erythrocyte sedimentation rate [(15.54±10.26) mm/1 h vs.(33.77±21.30) mm/1 h] and C-reactive protein [(4.79±12.94 ) mg/L vs.(16.33±23.43) mg/L] were obviously decreased, and the hemoglobin [(126.27±16.51) g/L vs.(110.58±16.45) g/L], hematocrit [(37.03±3.95)% vs.(33.52±4.32)%], and albumin levels [(42.30±3.03) g/L vs.(37.13±5.68) g/L] were remarkably increased compared with those before treatment ( t=3.932, 1.993, -3.398, -3.060, -4.009, all P<0.05). Height for age Z score and body mass index Z score were increased after IFX treatment, without statistically significant differences (all P>0.05). Conclusions:IFX therapy had good clinical efficacy in controlling inflammatorys and inducing clinical remission in pediatric CD.
ABSTRACT
Objective To investigate the protective effect of Carbachol on hyperoxia-induced acute lung injury (HALI) in mice and its related mechanisms. Methods Thirty-two healthy male ICR mice were randomly divided into four groups:control group, hyperoxia exposure three days group (HO3d group), hyperoxia exposure three days + Carbachol group (HO3d+Carba group), and Carbachol group (Carba group), eight mice in each group. The pathological changes of lung tissue in each group were observed under light microscope after the models were completed in each group.The expression of TLR4 and NF-κB protein in lung tissues were detected by Western blot, and the expression of HMGB-1 and TNF-α mRNA in lung tissues by RT-PCR. LSD-t test was used for sample pairwise comparison, and one-way ANOVA for intergroup comparison. P<0.05 was considered statistically significant. Results There was no statistical difference between the control group and the Carba group (P> 0.05), and no obvious abnormal changes in lung tissue structure. The expression of TLR4, NF-κB protein and HMGB-1 and TNF-α mRNA in the HO3d group were significantly higher than those in the control group (P<0.01), and there were obvious bleeding on the surface of the lung tissue and severe pathological damage. The expression of TLR4,NF-κB protein and HMGB-1 and TNF-α mRNA in the HO3d+Carba group were significantly lower than those in the HO3d group(P<0.01), while lung tissue damage degree was also lower than that in the HO3d group. Conclusions Hyperoxia can increase the expression of TLR4 and NF-κB in lung tissues, and cause inflammatory injury in lung tissue. Carbachol can reduce the release of HMGB-1 and TNF-α inflammatory factors in hyperoxia-induced acute lung injury, and its mechanism is related to the inhibition of TLR4/NF-κB signal pathway, which has a protective effect on HALI.
ABSTRACT
With the progress of clinical understanding and examination methods,the incidence of primary intestinal lymphangiectasia in children is gradually increased,congenital lymphatic malformation is the most common pathogen,protein-losing enteropathy is the main clinical feature.In addition to endoscopic and histologic examination,lymphatic radionuclide imaging,has become the common method in diagnosis,especially suitable for infants and young children.The management of lymphangiectasia include:a low-fat diet associated with supplementary medium chain three acyl glycerol,symptomatic treatment,medicine and surgery.Emphasis should be put on long-term management and follow-up work.
ABSTRACT
Objective@#To summarize the clinical data including manifestations, diagnosis, treatment and prognosis of eosinophilic gastroenteritis (EGE) in children.@*Methods@#A retrospective analysis was performed in 71 patients with pathologically proven EGE at Beijing Children's Hospital Affiliated to Capital Medical University from January 2008 to January 2017. Their clinical manifestations, laboratory and imaging examinations, endoscopic findings, histopathological examinations, and treatment were collected and analyzed.@*Results@#Among 71 EGE cases, 47 (66%) cases were male and 24 (34%) cases were female, and the median age was 9.2 (0.2-16.5) years old. The main clinical manifestations included abdominal pain (76%, 54/71), vomiting (68%, 48/71), anorexia (54%, 38/71), weight loss (38%, 27/71), and diarrhea (37%, 26/71). There were 27 cases (38%) with a history of allergic diseases or family history. The median absolute value of eosinophil in peripheral blood of the 71 patients was 0.4 (0-36.8)×109/L, and 27 cases (38%) showed an increase in eosinophil counts. Serum IgE was measured in 52 patients (104.3 (3.4- 3 000.0)×103 U/L), and 30 patients (58%) showed an increase in serum IgE. A large number of eosinophils ((41.0±8.5)/HP) were found in 3 patients' ascites. The endoscopic examination of upper gastrointestinal tract revealed hyperemic edema in 62 cases (87%), plaque in 44 cases (62%), erosion in 17 cases (24%) and ulceration in 16 cases (23%). Histopathologically, in 8 cases (11%) the disease involved both stomach and duodeneum, in 21 cases (30%) involved stomach only, and in 37 cases (52%) involved duodeneum only. In addition, in 6 cases (8%) the disease involved esophagus and in 10 cases (14%) involved colorectum. Microscopically, eosinophil counts averaged 67/HP, 33/HP, 40/HP and 38/HP in esophageal, gastric, duodenal and colorectal mucosa respectively. A total of 34 cases were treated with glucocorticoid, and all these patients had alleviation of symptoms, which occurred within 14.9 days on average, but EGE recurred in 11 cases (32%).@*Conclusions@#The clinical symptoms and endoscopic findings of EGE are diverse and nonspecific. Histopathological examination of gastrointestinal mucosa is particularly important for the diagnosis. Glucocorticoid treatment is effective, but the patients with EGE are prone to relapse.
ABSTRACT
Objective@#To analyze the clinical manifestations, diagnosis, treatment and prognosis of intestinal lymphangiectasia (IL) in children in order to improve the skills of diagnosis and treatment of IL.@*Method@#Clinical manifestations, laboratory findings, gastroscopic findings, histopathological examinations and lymphatic radionuclide imaging assessments were analyzed retrospectively among 47 IL patients who were hospitalized in the Gastroenterology Department of Beijing Children's Hospital Affiliated to Capital Medical University from June 2007 to December 2015. All patients were followed up by telephone. According to the various causes, the patients were divided into the primary intestinal lymphangiectasia (PIL) group and secondary IL group, and their clinical manifestations were compared by t test, Rank sum test or Chi-square test.@*Result@#In 47 IL patients, there were 38 children (81%) younger than 3 years old. There were 43 PIL patients (91%) and 4 secondary IL patients (9%). Between PIL and secondary IL, there were statistical differences in serum albumin (t=-3.950, P<0.005) , globulin(t=-2.850, P=0.007), age of onset(U=27.000, P=0.024), age at diagnosis(U=29.000, P=0.030) and course of disease(U=26.500, P=0.023), whereas there were no statistical differences in lymphocyte count, IgG, lymphatic radionuclide imaging, histopathology and gender(all P>0.05). Edema (44 cases, 94%), diarrhea (42 cases, 89%), accompanied with infection (35 cases, 74%) and ascites (30 cases, 64%) were the main clinical manifestations. In 47 IL patients, 45 patients were done gastroscopy and histopathological examinations, and there were 31 patients' histopathological examinations(69%) were positive. Forty patients were done lymphatic radionuclide imaging, and there was evidence of protein losing from gut via lymphatic radionuclide imaging in 39 patients(98%). Among 47 patients, 35 patients (74%) were followed up, 32 patients had good prognosis, 2 patient failed to show evidence of improvement, 1 patient died and no patient experienced a relapse till the end of the follow-up. In 35 patients, 28 patients were treated with medium chain triglycerides (MCT) dietary therapy, 26 patients showed improvement in symptoms, and 2 patients had no improvement. Among 35 patients with follow-up, there were 6 patients received surgical treatment, and their symptoms were improved.@*Conclusion@#PIL are the majority of IL in children younger than 3 years old. The main clinical manifestations are edema, diarrhea, accompanied with infection and ascites. For the patients without the evidence of lymphangiectasia from duodenum histopathological examination, further consideration of lymphatic radionuclide imaging, clinical manifestations, and laboratory studies are needed to make a final diagnosis. MCT dietary therapy is the cornerstone of IL medical management.
ABSTRACT
Objective@#To increase the recognition of pancreatic cystic fibrosis (PCF) in children and facilitate diagnosing and treatment of this rare entity.@*Method@#This is a retrospective analysis of children who presented to Beijing Children′s Hospital affiliated to Capital Medical University from January 2010 to December 2015. We describe their clinical features, laboratory testing and management.@*Result@#Eleven children were diagnosed with PCF by genetic testing or sweat chloride test during these 5 years, including 4 boys and 7 girls. Their age ranged from 0.5-14.3 (mean 9.0±3.9) years. Family history was positive in 3 children. Significant clinical findings on presentation were: malnutrition 6, including 2 cases of mild, moderate and severe malnutrition each; diarrhea 4 (yellow mushy or watery stool with frequency ranging from 2-5 times a day), including 1 case of acute diarrhea and 3 of chronic diarrhea, 3 of them had steatorrhea; abdominal pain 3. All of them had pancreatic lesions shown by abdominal ultrasound. Blood tests showed 6 cases had elevated serum amylase and lipase. The main treatment was pancreatic replacement therapy and nutritional support.@*Conclusion@#PCF is rare in children. Malnutrition, diarrhea and abdominal pain are the main clinical manifestations. Treatment is mostly pancreatic enzymes replacement and supportive care.
ABSTRACT
Objective To explore the clinical features,efficacy and prognosis of different treatments for children with achalasia of cardia(AC).Methods In this retrospective study,the clinical features,laboratory examination and treatment of 36 children with AC who had been admitted to Department of Gastroenterology,Beijing Children's Hospital,Capital Medical University from August 2006 to September 2015 were reviewed,and the efficacy and prognosis of different treatments were compared.The symptoms of the children were graded using the AC clinical symptom score(Eckardt score),and the Eckardt score ≤ 3 scores was defined as the effective treatment.SPSS 19.0 statistical software was used to analyze the data,and P<0.05 for the difference was statistically significant.Results Thirty-six children with AC included 24 boys and 12 girls.Ages ranged from 1.4 to 15.5 years old,with a mean age of(10.0±3.4)years old.Course of disease ranged from 1 month to 9 years,with a mean course of 0.5(0.2,3.0)years.In the 36 children,33 cases(91.7％)had vomiting,23 cases(63.9％)had dysphagia,16 cases(44.4％)had weight loss,and 9 cases(25.0％)had chest pain.The effective rates of treatment in surgical treatment group and drug treatment group were 100.0％(13/13 cases)and 71.4％(5/7 cases),respectively in 3 months,and there was no significant difference between the 2 groups(P=0.111).The effective rates of treatment were 100.0％(13/13 cases)and 50.0％(3/6 cases),respectively in 6 months,and the difference was statistically significant between the 2 groups(P=0.021).Within 12 months,there was no recurrence in surgical treatment group and the effective rate was 100.0％.Children in drug treatment group had 1 case who stopped taking medicine,while the other children received surgical treatment in other hospitals due to poor drug treatment.Conclusions Drug and surgical treatment of AC both have good short-term effect,however,the medium and long-term efficacy of surgical treatment is higher than that of drug treatment in children.Symptomatic relief is more stable,and symptom is not easy to relapse for the children with surgical treatment.
ABSTRACT
Objective To investigate the etiology and clinical characteristics of chronic pancreatitis (CP) in children,so as to improve its diagnosis and treatment.Methods The etiology,clinical characteristics,radiological records and therapy were retrospectively analyzed in children with CP who were admitted to Beijing Children's Hospital Affiliated to Capital Medical University from July 2006 to May 2014.Results A total of 29 medical records of children with CP,including 19 male and 10 female,with a mean age of (8.5 ± 3.7) years,and the youngest case was a 2-year-old child,the oldest case was a 15-year-and-2-month-old child.The main etiological factor was idiopathic pancreatitis (51.7％,15/29 cases),and 9 cases were caused by anatomical anomalies (31.0％,9/29 cases).The main symptoms included abdominal pain (89.7％,26/29 cases),malnutrition (48.3％,14/29 cases),nausea and vomiting (31.0％,9/29 cases),and chest distress and dyspnea (17.2％,5/29 cases).The serum amylase level in 18 cases (62.1％) increased.The positive diagnostic rate of transabdominal ultrasound was 96.6％ (28/29 cases),and dilations of pancreatic ducts or/and intraductal stones were 82.8％ (24/29 cases).The positive rate by magnetic resonance cholangio-pancreatography (MRCP) for morphological changes in pancreas was 88.5％ (23/26 cases),and dilations of the pancreatic ducts were 80.8％ (21/26 cases).A total of 10 endoscopic retrograde cholangio-pancreatography (ERCP) procedures were performed on 6 children,and pancreatic ductal stenosis or dilations were detected in them.All the patients were treated conservatively at first,and then 7 cases of them had surgical therapy (oledochojejunostomy,choledochoduodenostomy,choledochocystectomy,etc.),aud 6 cases had stent insertion by ERCP.Conclusions The main causes of CP in children are idiopathic and anatomical anomaly,and its diagnosis is based on symptoms and imaging changes;surgical or endoscopic therapy can be used if internal therapy is not effective.

ABSTRACT
The pulmonary capillary vessels and alveoli of rats were injected by methyl methacrylate and investigated by means of a scanning electron microscope. The network of subpleural capillary was sparse and the holes of vascular rings were large. Some vessels turned back to be acute angles and some were observed as blind channels.The ne-twork of alveolar capillary enlarged flatly and fused together as a dense sheetlike network.The alveolar casts were polyhedrons and different in size and shape.There were markes of alveolar type cell in the surface of alveolar casts.The alveolar holes connected with two alveoli were like bridges or three-connectd tubes
