Objective To investigate the remote effects of epidermal growth factor(EGF)and early removal of eschar combined with skin grafting for the treatment of skin lesion produced by mustard gas.Methods A 3-year follow-up survey was condueted in 39 patients with skin lesion produced by mustard gas.The condition of healing was observed and evaluated.Results Good epithelial healing with pigmentation was observed in all the surveyed patients,and only in a few of them showed local recurrence of wound.Itching and paresthesia in the wounded parts were the main complaints.The sequelae remained unpredictable.Conclusion The early use of epidermal growth factor and early removal of eschar followed by skin grafting for the treatment of skin lesion produced by mustard gas may achieve satisfactory therapeutic effect.

Objective To study the morphological changes in peripheral blood cells and bone marrow cells of the patients suffering from mustard gas poisoning and their relationship with the degree of poisoning. Method The peripheral blood cells and marrow cells were examined morphologically after mustard gas poisoning. Results The total WBC count was reduced progressively in 44 patients, among them 10 patients showed granulocytopenia or agranulocytosis. Severe injury to eosinophils was seen also in the early period, and the percentage and absolute value of lymphocytes were significantly lowered too. However, platelets were not significantly influenced. The red cell count and hemoglobin level were elevated because of hemoconcentration. Blood marrow cells showed marked morphological changes. WBC became swollen with appearance of poisonous granules and vacuoles in their cytoplasm. Deformed lymphocytes (LY) could be found in the marrow cells of all the patients, mainly in the form of immature lymphocytes. It was shown that mustard gas produced serious damage to the hematopoitic cells of the bone marrow in the early period. Conclusions The examination of pheripheral blood and bone marrow cells is an important measure to determine the degree of mustard gas poisoning. The decrease in the absolute value of lymophocyte count and the time of its recovery, and degree of inhibition of hematopoiesis are closely related to the degree of mustard gas poisoning.

Objective To analyze the clinical characteristics and prognosis of 4 rare types of non -Hodgkin lymphoma(NHL)in children,and to discuss the progress in treatment.Methods Clinical data of 1 4 patients with rare types of NHL at Shanghai Children′s Medical Center,Shanghai Jiaotong University School of Medicine between January 2004 and December 201 4 were retrospectively analyzed,and their clinical features,treatment and prognosis were dis-cussed.Results Fourteen cases were reported including 6 subcutaneous panniculitis -like T -cell lymphoma (SPTCL),3 hydroa vacciniforme -like cutaneous lymphoma(HVLL),2 pediatric follicular lymphoma(PFL)and 3 ex-tranodal NK/T -cell lymphoma,and nasal type(ENKTL).Ten patients (71 .4%)primarily presented with skin lesions and underwent a long course of illness before they were finally diagnosed (the median was 1 0 months),71 .4%(1 0 /1 4 cases)of them associated with fever and 50.0%(7 /1 4 cases)with liver and spleen enlargement,and no evidence of central nervous system (CNS)and bone marrow (BM)involvement was observed,while 28.6% patients (4 /1 4 cases) had more than two lines′abnormalities in peripheral blood examination.Since there were no standard treatment guide-lines,most patients received CHOP (Cyclophosphamide +Adriamycin +Vincristine +Prednisone)and /or mature B -cell NHL -like therapy,and 50.0%(7 /1 4 cases)of them received interferon therapy in addition,while 1 patient re-ceived allogeneic hematopoietic stem cell transplantation after recurrence.The complete remission was achieved in 71 .4%(10 /14 cases)of all the patients.Two of them died,3 lost follow -up,and 1 relapsed.The 3 -year overall survi-val and event free survival rates were 0.84 and 0.57,respectively,after a median follow -up of 26 months (range 12 -64 months).Conclusions Pediatric rare types of NHL show atypical clinical manifestation,low incidence of CNS /BMinfil-tration and long course.It is hard to make pathological diagnosis and differentiation.It is also inappropriate to apply the commonly used staging system to these rare types of NHL.No standard treatment has been found by now.SPTCL,HVLL and PFL have relatively good outcomes when treated with mature B -cell NHL -type therapy plus interferon therapy.

Objective:To investigate the effect of pelvic motion in late pregnancy on the outcome of first trimester delivery.Methods:A total of 127 first-borns admitted to the midwifical clinic of Nanjing Maternal and Child Health Hospital from November 1, 2019 to March 10, 2020 were selected as the research objects, and they were divided into the walking group and the pelvic motion group according to the random number table method. In the end, 62 cases were included in the walking group and 65 cases in the pelvic motion group. The walking group did brisk walking in the third trimester. In the pelvic motion group, the motion in the third trimester consisted of the combined pelvic motion involving the two planes of the upright spine and the horizontal spine, and multiple peripelvic joints. The changes of fertility, birth canal and fetus before and after exercise were observed, and the outcomes of childbirth were compared between the two groups.Results:Indicators reflecting productivity: persistence time of "air bike" on the day before delivery was (27.12±7.73) seconds in the pelvic motion group and (20.56±6.60) seconds in the walking group, the difference was statistically significant ( t value was 5.12, P<0.01). The time of contractions after exercise before delivery was (269.38±123.70) seconds in the pelvic motion group and (591.29±201.82) seconds in the walking group, the difference was statistically significant ( t value was 10.89, P<0.01). The indicators reflecting the situation of the maternal birth canal were as follows: "sitting forward flexion level", pelvic motion group was (33.64±5.91) cm, walking group was (29.50±5.28) cm, the difference was statistically significant ( t value was 4.15, P<0.01). The cervical score during regular contractions was 8.01±1.69 in the pelvic motion group and 7.30±1.40 in the walking group, the difference was statistically significant( t value was 2.56, P<0.05). At the beginning of regular contractions, the proportion of fetal "occipital position" was 93.85% (61/65) in the pelvic motion group and 72.58%(45/62) in the walking group, the difference was statistically significant ( χ2 value was 10.41, P<0.01). The "no pain rate after exercise the day before delivery" was 72.31% (47/65) in the pelvic motion group and 29.03% (18/62) in the walking group, the difference was statistically significant ( χ2 value was 25.30, P<0.01). Time of the first labor was (395.84±165.24) min in the pelvic motion group and (574.35±152.23) min in the walking group, the difference was statistically significant ( t value was 6.32, P<0.01). The second stage of labor was (25.98±9.88) min in the pelvic motion group and (33.62±13.94) min in the walking group, the difference was statistically significant ( t value was 3.57, P<0.01). Conclusions:Pelvic motion in middle and late pregnancy can affect labor force, birth canal, fetus and other delivery factors, reduce movement pain and shorten the time of labor.

Objective To assess the diagnostic potential of circulating galactomannan (GM),(1,3)-β-D-glucan (BG), and a combination of both biomarkers among high-risk pediatric patients.Methods Circulating GM antigen was detected by ELISA kits (Platelia~(TM) Aspergillus) and BG antigen by a turbidimetric kinetic method (GKT-5M Set Kinetic Fungus Detection Kit).Positive tests were defined by two consecutive values of GM index ≥0.5 or by a single value ≥0.8, and by BG detection ≥ 10 pg/ml.Results A total of 130 patients were enrolled.Two was identified with proven IFI, twenty probable IFI.Sensitivity, specificity were 81.8%, 82.4% for plasma BG detection, respectively; 75.0%, 94.4% for GM detection, respectively; 50.0%, 96.3% for combined GM and BG detection, respectively.Conclusions Both circulating GM and BG detections are available for most of the common pathogens and demonstrated desirable sensitivity and specificity among pediatric high-risk population.Both assays can be used as prospective screening tools.Combination of detections of both biomarkers would improve specificity for IA diagnosis.

Objective To improve understanding of the clinical manifestations, diagnosis and treatment of childhood Kasabach-Merritt phenomenon (KMP). Methods The clinical data of 13 patients admitted for KMP to XXX from January 2010 to January 2016 was retrospectively analyzed, with a review of relevant literature. Results The patients were 10 males and 3 females. The age of presentation varied from newborn to 5 months. 12 patients had cutaneous manifestations, like petechiae, ecchymosis, jaundice, skin masses, etc, 1 patient had pleural effusion. The location of lesions varied. The laboratory hallmark consists of profound thrombocytopenia and hypofibrinogenemia with elevated D-dimers. The median time from initial presentation to diagnosis was 60 days. After approaches like surgery, corticosteroids, propranolol, interferon, sirolimus, etc, 10 patients got remission while 3 patients died. 6 patients treated with sirolimushad complete response. Conclusions KMP is characterized with vascular tumor, severe thrombocytopenia and consumptive coagulopathy. Clinically, KMP often presents with early-onset and delay in diagnosis. Surgery is an effective approach for KMP. Sirolimus appears to be a promising treatment for KMP.
