Background and purpose: Langerhans cell histiocytosis (LCH) is a rare complex reticulocndotheliai disease that often invades the head and neck. There in no consensus of treatment. Radiation is one of the treatment options for the localized lesions. Our aim in the study was to analyze the radiotherapeutic efficacy for LCH in the head and neck region. Methods: 8 patients with eosinophilic granuloma (EG) and 1 case with Hand-Schuller-Christian disease (HSC) were treated with radiotherapy in our hospital from July 2000 to May 2007. Their clinical data were retrospectively analyzed. Results: 5 cases of EG were treated with tumor partial excision and radiation, while the other 3 cases of EG were given radiation alone after biopsy. The HSC was administered with radiation and endocrine therapy. All the patients were followed up for 1.5-8 years. The response rate was 89%. Conclusion: Radiotherapy of LCH is an effective modality, but the optimal dose needs to be further studied.

Purpose To explore the findings and diagnostic values of apparent diffusion coefficient (ADC) and diffusion weighted image (DWI) of the portal venous tumor thrombus (PVTT) caused by hepatic carcinoma.Materials and Methods Thirty-one patients with hepatic carcinoma (43 lesions) with 63 PVTT in the main branches and trunks diagnosed by clinical and MRI were enrolled. All patients underwent conventional MRI (cMRI) imaging, DWI and ADC imaging, the features of cMRI, DWI and ADC were observed, the relevance of ADC values between the hepatic carcinoma lesion and PVTT were analyzed.Results Among the total 43 lesions, DWI image showed low signal, iso-signal and high signal in 1, 4 and 38 lesions, respectively; and ADC image showed low signal, iso-signal and high signal in 36, 5 and 2 lesions, respectively. In the total 63 PVTT, DWI showed low signal, iso-signal and high signal in 4, 7 and 52 lesions, respectively;while their ADC images showed low signal, iso-signal and high signal in 54, 6 and 3 branches, respectively. There was good consistency for the results of two observers on the findings of ADC of tumor lesions (Kappa=0.8334,P<0.05), and a moderate consistency on that of PVTT (Kappa=0.5215,P<0.05). The average ADC value of tumor lesion and PVTT was (1.127±0.268)×10-3 mm2/s and (1.021±0.363)×10-3 mm2/s, respectively; there was a correlation of the mean values of ADC between tumor lesion and PVTT (r=0.246,P<0.05). Conclusion The features such as low signal and low value on ADC image and high signal on DWI obtain a certain clinical application value for qualitative diagnoses of PVTT.

Objective:To observe the changes of blood glucose,insulin and dipeptidyl peptidase-Ⅳ(DPP-Ⅳ/CD26)on type 2 diabetes mellitus in rabbits after HUCBSC( human umbilical cord blood stem cells) transplantation. Methods:18 rabbits were randomly divided into normal control group (6 rats,Group C) and diabetic model group (12 rats). After preparation model of type 2 diabetes,and 6 rats of them were treated with HUCBSC ( CD45+,CD34-) transplantation by ear vein transfusion ( Group A) ,and 6 rats were treated with PBS(Group B). All three groups of rabbits were fed for 4 weeks,and the blood glucose was monitored every day,and the level of blood insulin and DPP-IV/CD26 were measured every week. Results:The negative expression rate of CD34 in HUCBSC was 96. 5%. The positive expression rate of CD45 in HUCBSC was 100%. Compared with non transplantation group,the blood glucose and DPP-IV/CD26 in the umbilical cord blood stem cell transplantation group were gradually decreased,and insulin level was gradually increased, the difference was statistically significant (P<0. 01). Conclusion:HUCBSC were round or oval,with adherent growth,HUCBSC trans-plantation can significantly reduce blood glucose, increase insulin secretion, reduce the level of DPP-IV/CD26, the immunological phenotype of HUCBSC was CD45+,CD34-,thus providing a new theoretical basis for the clinical treatment of diabetes and its complica-tions.

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.

Objective To evaluate the clinical curative effect of ulinastatin combined with CRRT in the treatment of multiple organ dysfunction syndrome(MODS).Methods Sixty eight patients with MODS who were admitted to ICU from July 2013 to July 2015 were randomly divided into three groups:control group,CRRT group,combined group;Patients' APACHE Ⅱ,SOFA scores level of inflammatory markers were recorded before treatment and after treatment of 72 hours and 7 days.The mortality of the three groups in ICU were compared.Results After 72 hours and a week of treatment,the level of IL-10,IL-6,TNF-α,WBC、PCT、CRP in CRRT group and combined group were significantly better than that of control group(P＜0.05),and combined group were significantly better than that of CRRT group.Compared with the control group,the oxygen index,lactic acid,ALT significantly im proved in CRRT group and combined group were better than control group,after 72 hours and a week of treatment(P＜0.05),and the cornbined group was the most obvious.After a week of treatment,the mortality rate of CRRT group and combined group was significantly better than the control group (P＜0.05),while there was no statistical differences between CRRT group and combined group(P＞0.05).Conclusion Ulinastatin combined with CRRT is an effective method for the treatment of MODS.

Objective To investigate the changes of serum cardiac-specific troponin I (cTnI) level in patients after lung transplantation. Methods Clinical data of patients undergoing lung transplantation in our hospital from December 2016 to December 2022 were retrospectively analyzed. The relationship between postoperative serum cTnI level and clinical characteristics were explored. Results Finally 20 patients were collected, including 15 males and 5 females with an average age of (51.65±12.79) years. The serum cTnI level was significantly increased after lung transplantation. The serum cTnI reached the highest level on the first day after transplantation, and significantly decreased from the third day after transplantation. The serum cTnI levels in patients with obstructive pulmonary disease and bilateral lung transplantation were significantly higher than those in patients with restrictive pulmonary disease and unilateral lung transplantation on the day after surgery and on the first day after transplantation. Conclusion Transient myocardial injury can occur after lung transplantation, which is characterized by an abnormal increase in serum cTnI level.
