Objective In this article,we report and discuss the clinical presentation of antithyroid drug(ATD)-induced agranulocytosis.Methods We retrospectively studied 36 cases of ATD-induced agranulocytosis over the past 14 years in PUMC hospital.Results ATD-induced agranulocytosis patient's age ranged of 16-62 years old.88.9％ of ATD-induced agranulocytosis occured with a large ATD treatment.91.7％ patients occured in the first three month of drug therapy.A case occured agranulocytosis when 8 months duration.94.4％ patients occurs secondary infections.Conclusion This study showed that ATD-induced agranulocytosis considered to be dose dependent,not irrelevant to sex,age and the drug.

The epidemic characteristics of differentiated thyroid cancer(DTC)are changing, thyrotropin(TSH)suppressive therapy is also improving in recent years. The risks of recurrence and the death of patients, as well as the adverse effects of levothyroxine sodium treatment should be fully considered during thyroid hormone administration for patients of DTC. Hence, the degree of TSH suppression should be individualized in patients with DTC.

T),resulting in His to Leu(CAT→CTT) substituted at codon 435(H435L).No mutation was identified in the patient's parents.HT occurred in the patient during following-up.Conclusion H435L mutation in exon 10 of TR? gene leads to resistance to thyroid hormone.Meanwhile,consistent RTH might lead to HT.

Langerhans cell histiocytosis is an uncommon disease, involvement of the thyroid by langerhans cell histiocytosis is rare. Two cases of Langerhans cell histiocytosis of the thyroid confirmed by pathology were reported in this paper. The main clinical feature was enlargement of the thyroids. One patient had hypothyroidism. Meanwhile, the lungs and pituitaries of the two patients were affected. Langerhans cell histiocytosis of the thyroid had no typical symptoms and specific laboratory examination, and might be clinically diagnosed as chronic lymphocytic thyroiditis, benign or malignant thyroid tumors. Thyroid fine needle aspiration cytology might be useful in confirming the diagnosis. The effective treatments include systemic chemotherapy, local radiation therapy and surgical excision. The chemotherapy is still the major technological approach. Most patients can relieve partially after receiving the systemic chemotherapy.

Objective To explore the clinical features and endoscopic manifestations of eosinophilic gastroente-ritis(EG)in children.Methods A retrospective analysis was conducted of the clinical manifestation,laboratory examination,endoscopy(upper and/or colonoscopy)performance,diagnosis and treatment of 49 cases of patients who were diagnosed as EG in Children's Hospital of Nanjing Medical University from July 2013 to July 2015.Results The common clinical manifestations of EG in children were hematochezia(23 cases),diarrhea(20 cases),vomiting(18 cases)and abdominal pain(15 cases).The ages of children admitted to hospital for the first time ranged from 1 month and 7 days old to 13 years and 7 months old,and the mean age was 59.4 months old,in which most patients were younger than 1 year old,accounting for 38.77％(19 cases)of all.Peripheral blood eosinophilia was present in 20 cases(40.82％)of the patients,and only 6/18 cases(33.33％)of the patients had elevated serum IgE.Upon endoscopic analysis,the lesions involved esophagus(4 cases),stomach(14 cases),duodenum(20 cases),small intestine(15 cases),colon(28 cases)and rectum(6 cases),and the most common manifestation under gastroscopy was mucosal hyperemia edema(27 cases)and erosion(9 cases),while the most common manifestation under colonoscopy was mucosal hyperemia edema(25 cases)and nodular hyperplasia(24 cases).All patients improved with food restriction,in which 8 cases were treated with glucocorticoid while 9 cases with oral Singulair and 9 cases with oral Loratadine.All children with symptoms were alleviated somewhat,but 5 cases of them relapsed after drug withdrawal.Conclusions The clinical manifestations of EG in children varied and were mainly hematochezia,vomiting,diarrhea and abdominal pain.Some patients had the elevated peripheral blood eosinophilia and serum IgE.The most common manifestations under gastroscopy were mucosal hyperemia edema and erosion while the most common manifestations under colonoscopy were mucosal hyperemia edema and nodular hyperplasia.

Objective To determine the association of acanthosis nigricans(AN) with values for estimating insulin resistance and adipocytokine levels in simple obese children. Methods These subjects concluded 38 simple obese children. AN was present in 17 of 38 children. Height, weight and abdominal circumference were recorded and fasting blood sample was obtained for measurement of blood glucose, plasma insulin, leptin, and plasminogen activator inhibitor 1 (PAI-1) levels which were known as the risk factors of cardiovascular disease. We obtained homeostasis model assessment insulin resistance index (HOMA-R) by fasting blood glucose and plasma insulin levels. Results The severity of obesity, abdominal circumference, fasting insulin levels and HOMA-R were significantly higher in obese children to AN compared to those without AN. There was the tendency that children with AN had higher levels of leptin and PAI-1 compared to children without AN. Conclusions These results suggest that obese children with AN may have a risk of cardiovascular disease as well as type 2 diabetes mellitus.

Objective To assess the safety, efficacy, temporary side effects and feasibility of oral ibuprofen suspension in the treatment of patent ductus arteriosus (PDA) with hemodynamic significance in premature infants. Method A randomized controlled trial including seventy-four premature infants with PDA was performed from February 2007 to May 2008. Infants were randomly assigned to two groups: testing group (36 patients) received three doses of oral ibuprofen suspension (10 mg/kg at 24-hour intervals) and control group (38 patients) did not receive such treatment. The cure rate of PDA, relative side effects of ibuprofen and complications during treatment were recorded.Results The closure rate of ductus arteriosus in the testing group was 52.8% (19/36), which was higher than that of control group (18.4%, 7/38) (χ2=9.575, P=0.002). The severe side effects did not occur in testing group, such as oliguria, renal impairment, prone of bleeding, gastrointestinal perforation and novel appearing or deteriorative of intraventricular hemorrhage (IVH). Compared with the infants in control group (26.3%, 10/38), the morbidity of abdominal distension or gastric retention in testing group (33.3%, 12/36) was higher, while there was no statistically significant difference (χ2=0.436, P=0.509). The hospital stay [(22.8±14.8) d vs (24.1±17.1) d], mechanical ventilation rate [5.6% (2/36) vs 2.6% (1/38)] and oxygen supplement time [(8.3±9.3) d vs (8.8±8.3) d] between the testing and control groups remained no significant difference (P>0.05). Conclusions Oral ibuprofen suspension could be effective in closing PDA of preterm infants; no significant complications and side-effects occurred during oral ibuprofen treatment. It is suggested that oral ibuprofen suspension treatment was safe, effective and well tolerated for preterm infants with PDA.

OBJECTIVETo explore the application of protective appendicostomy after sphicter-preserving surgery for patients with low rectal carcinoma who are at high-risk of anastomotic leakage.

METHODSClinical data of 74 low rectal cancer cases with high-risk anastomotic leakage undergoing laparoscope-assisted total mesorectal excision(TME) sphincter-preserving operation in our department from September 2013 to September 2014 were analyzed retrospectively. Patients were randomly divided into two groups: 36 patients received appendicostomy and catheter was removed 4 to 6 weeks after operation when sinus tract formation in abdominal wall was identified; 38 patients received traditional ileostomy and stoma closure was performed 3 to 6 months after operation.

RESULTSThe operation time was (149.2±9.4) min vs. (146.7±12.7) min, postoperative complication morbidity was 8.3%(3/36) vs. 13.2%(5/38), anastomotic leakage rate was 2.8%(1/38) vs. 2.6%(1/36), mean drainage volume of 1-week stoma was (203.2±76.9) ml vs. (195.8±76.5) ml, intestinal function recovery time was (25.5±5.6) h vs. (24.0±5.8) h in intubation colostomy group and ileostomy group respectively, and these differences were not significant (all P>0.05). While total hospital stay was shorter and cost was less in intubation colostomy group as compared to ileostomy group [(8.8±1.7) d vs. (18.0±1.7) d, (32 000±3000) yuan vs. (51 000±4000) yuan], and these differences were significant (all P<0.05).

CONCLUSIONFor low rectal cancer patients who are at high-risk of developing anastomotic leakage undergoing sphincter-preserving anterior resection, protective appendicostomy can decrease anastomotic leakage rate, avoid second stoma closure, shorten hospital stay and reduce hospital cost.

creatinine concentration. Conclusion Bisphosphonates can decrease serum total calcium levels in hypercalcemia crisis caused by PHPT effectivelywith mild adverse events.

Objective:To explore the influencing factors of hospitalization cost of acute myeloid leukemia, to group the cases based on decision tree model and to provide reference for improving the DRG management in this regard.Methods:Homepage data were retrieved from the medical records with acute myeloid leukemia as the main diagnosis (the top four ICD codes were C92.0, C92.4, C92.5, and C93.0). These patients were discharged from the clinical hematology department of the Fujian Institute of Hematology from January 2020 to December 2021. Then the influencing factors of hospitalization expenses were identified using Wilcoxon rank sum test or Kruskal-Wallis rank sum test and multiple linear stepwise regression analysis, with such factors used as classification nodes. The decision tree model of χ2 automatic interactive testing method was used to group the cases so included. At the same time, the included cases were grouped according to the trial run C-DRG version in Fujian province, for comparison of the differences between the two grouping methods. Results:The length of stay, the type of treatment, whether associated complications and age of patients were found as the influencing factors for the hospitalization costs of patients with acute myeloid leukemia, and such factors were included in the decision tree model to form 9 case mixes. The variance reduction of this model was 75.77%, featuring a high inter-group heterogeneity, and the coefficient of variation was 0.33-0.61, featuring a low in-group difference. The patients were divided into two groups according to the C-DRG version in Fujian province. The variance reduction of this method was 27.57%, featuring a low inter-group heterogeneity, and the coefficients of variation were 0.59 and 1.25, featuring high in-group difference.Conclusions:The cases of acute myeloid leukemia were grouped based on length of stay, type of treatment, whether accompanied by complications, and age proved reasonable enough to serve as reference for DRG management and cost control of this disease.
