Objective To discuss the mode of onset,clinical characteristics,treatment and prognosis of children with granulocyte sarcoma (GS),in order to provide guidance for early diagnosis and effective treatment of GS.Methods Six cases of children with GS diagnosed at the Department of Hematology,Children's Hospital Affiliated to Soochow University between June 2009 and June 2014 were analyzed,the data including the mode of onset,clinical manifestation,diagnosis,treatment and outcome.Results There were 2 cases with a painless mass onset (1 case was 2 years old,characterized by right waist mass,about 10 cm × 5 cm;the other case was 6 years old,characterized by axillary lump,about 2 cm × 3 cm),and both of them received surgical removal of the tumor,then the postoperative tumor was examined by pathologic and immunohistochemical method,and at last the primary granulocyte sarcoma was diagnosed.The third case was a 7 years old girl,she was onset characterized by scalp lump,about 2 cm × 3 cm,and was diagnosed by the pathologic and immunohistochemical method,and changes in hematological system appeared a month later and acute myeloid leukemia(AML) was confirmed by bone marrow examination.The onset ages of other 3 cases were in 10 months,1 year and 7 months,13 years and 3 months old respectively,characterized by scalp lump (about 2 cm × 3 cm),spinal canal tumor (about 1.0 cm × 1.5 cm),intracranial tumors (6.0 cm × 4.9 cm),with AML occurring at the same time,which was confirmed by surgical pathology,immunohistochemistry and bone marrow cell morphology,immune classification,chromosome,and fusion gene diagnosis.Four cases were hematopoietic malignancies by pathology,2 cases of then belonging to small round cell tumor.The immune pathology showed 5 cases of myeloperoxidase positive,CD68-positive,3 cases of CD43-positive,CD123-positive.All children CD3,CD20 levels in all children were negative.Four cases underwent surgery combined with chemotherapy,other 2 cases received surgery and then gave up treatment,1 case discontinued follow-up 3 months later,and the other case died of intracranial hemorrhage after 3 months,which induced by thrombocytopenia.The treated 4 cases were followed up 3 to 58 months,and all had disease-free survival.Conclusions Children with GS have low incidence and non-specific diagnostic criteria,its diagnosis depends on immune pathology,and the treatment is mainly in accordance with AML program for high-dose chemotherapy.The systematic chemotherapy helps to prolong overall survival;at the same time,the hematopoietic stem cell transplantation with bone marrow may help to improve the prognosis.

Objective:To investigate the protective effects of Ghrelin on LPS-induced apoptosis of human alveolar epithelial A549 cells,along with the possible molecular mechanisms.Methods: CCK-8 assay was used to examine the cell viability of A549 treated by LPS.Apoptosis of A549 cells was measured by TUNEL.NO(Nitric oxide)production was detected by NO-specific fluorescent probe 3-Amino,4-aminomethyl-2′,7′-difluoresceindiacetate(DAF-FM DA).Western blot was also performed to examine the expressions of iNOS(inducible nitric oxide synthase),AKT,ERK,p-AKT,p-ERK and apoptotic proteins,such as Bcl-2,Bax,and cleaved caspase-3.Results: LPS exposure impaired cell viability and increased apoptosis of A549 cells significantly in concentration-and time-dependent manners accompanied with increased Bax and cleaved caspase-3 production,coupled with decreased Bcl-2 levels.Meanwhile,LPS promoted iNOS expression and the production of NO.Ghrelin pretreatment ameliorated LPS-caused alterations in the ratio of Bax/Bcl-2 and cleaved caspase-3 expression.TUNEL analysis showed that Ghrelin could decrease the apoptosis induced by LPS in A549(P<0.05).Simultaneously,LPS remarkably decreased the expression of p-AKT and p-ERK in A549 cells,which was abrogated by Ghrelin pretreatment.However,Ghrelin had no significant effect on NO production induced by LPS.Conclusion: Ghrelin reduces LPS-induced apoptosis of human alveolar epithelial cells partly through activating the AKT and ERK pathway,but the level of iNOS derived NO could not be reduced.

Objective To study the variation of the pancreatic head arteries and its value in pan- creas transplantation.Methods The DSA data of 300 cases were studied retrospectively:192 cases of celiac trunk angiography,102 cases of superior mesenteric artery angiography,and 6 cases of the com- bined.The distribution and variation of the arteries on the pancreatic head were observed.Results In the celiac angiography cases,typical gastroduodenal artery,superior pancreaticoduodenal artery and its branches were visualized in 73 cases(38%).The posterior superior panereaticoduodenal artery was not anastomosed with the posterior inferior pancraticoduodenal artery in 3 cases.The posterior pancre- aticoduodenal arcade was discontinued in 1 case.The anterior superior pancreaticoduodenal artery, posterior superior pancreaticodoodenal artery,and dorsal pancreatic artery were only distributed across the upper head of the pancreas separately but were not anastomosed each other in 1 case.The variation rate of pancreaticoduodenal arterial arcades was 6.8%(5/73).In 102 cases of the superior mesenteric artery angiography,the inferior pancreaticoduodenal artery was visualized in 42 cases(41%)while its branches were not visualized.In 6 cases of the combined angiography,superior panereaticoduodenal artery was visualized in all of the cases,of which anterior and posterior arcades were visualized in 4 cases(66.7%).The gastroduodenal artery reconstruction was performed in 3 cases of clinical pancre- as transplantation,all of the receivers maintained a normal blood glucose level after transplantation and no surgical complications were found.Conclusions The superior pancreaticoduodenal artery might of- fer more blood supply than inferior pancreaticoduodenal artery in the pancreatic head.The arterial re- construction of the transplanted pancreas should include the gastroduodenal artery because of the pos- sibility of arterial variation on the pancreatic head.

Objective To observe the of changes of cerebral blood flow and electroencephalography in chronic cerebral circulation insufficiency (CCCI) treated with fastigial nucleus stimulation (FNS) and hyperbaric oxygen (HBO). Methods 144 cases of CCCI were divided into 4 groups: 36 cases were treated with FNS and HBO, 36 cases with FNS, 36 cases with HBO, 36 cases without any treatment as control group. The blood velocity of anterior, middle, posterior cerebral arteries, vertebral artery and basilar artery were measured with transcranial Doppler (TCD) and the brain waves （α, β, δ, θ） were recorded with electroencephalography (EEG) before and after the treatment. Results Compared with the control, the brain blood velocity and α wave increased in all the treatment groups, especially in the HBO+FNS group, while β, δ, θ waves decreased (P<0.05). Conclusion FNS and HBO can increase cerebral blood flow and improve the cerebral function respectively.

Objectives To analyze the relationship between the multi-organ hypoxia damage and the death of acute high altitude sickness severe case. Methods 3220 cases from 1956. 06 to 2005.06 in the hospital were reviewed by questionnaire and the cases in MODS or death were screened out. The cause of death and feature were analyzed by the data as clinical symptom, physical signs and auxiliary examination. Results 281 cases complicated by MODS (include 35 dead cases) were found out by review. The incidence with MODS is 8.73% , and the death rate was 1.09%. The masculine incidence rate of the clinical symptom, physical signs and auxiliary examination in death were 2. 86% ~65. 71% , 2. 86% ~ 100% and 14. 29% ~ 100% , respectively. The MODS incidence in dead cases was 100%. Compared with the curing group, the MODS number, cardiac functional disturbance, brain disorder and renal functional disturbance in the death group had a significantly high incidence rate in all the 281 cases with MODS( P <0.05). With dependability analysis, there were a significantly direct correlation relationship between the death in the severe cases with acute high altitude sickness and the number of MODS ( r = 0. 3473, P < 0.001). Conclusion Hypoxia to the damage of multi-organ function play an important role in death of the severe cases with acute high altitude sickness in high attitude area, and the functional disturbance of important organs as heart, brain and kidney is the most important cause to death.

OBJECTIVETo study the influence of CD34(+) and T cells doses in grafts on prognosis after HLA-identical sibling allogeneic peripheral blood stem cell transplantation (allo-PBSCT).

METHODSSixty-five patients received HLA-identical sibling allo-PBSCT were studied. The numbers of CD34(+), CD3(+), CD3(+)CD4(+) and CD3(+)CD8(+) T cells in the grafts were measured by fluorescence-activated cell sorting (FACS). The doses of MNC, and the above cells in grafts were calculated as per kilogram of recipient's body weight. The patients were divided into high-dose (HD) or low-dose (LD) groups according to median dose of those cells, respectively. Hematopoiesis reconstitution, incidence of graft versus host disease (GVHD), transplant-related mortality (TRM), overall survival (OS), and disease-free survival (DFS) were analyzed.

RESULTSHD CD34(+) cells significantly accelerated neutrophil and platelet reconstitution (P < 0.05). There seems a trend toward increasing incidence of grade II approximately IV acute GVHD (aGVHD) in HD CD3(+)CD4(+) and CD3(+)CD8(+) T cells groups compared with those LD groups (P = 0.089 and 0.098, respectively). The TRM rates were significantly higher and OS rates were significantly in HD CD3(+)CD4(+) and CD3(+)CD8(+) T cells groups than in LD groups, respectively (both P < 0.05). Multivariate analyses showed that CD3(+)CD4(+) and CD3(+)CD8(+) T cells doses in grafts were significant risk factors for TRM \[relative risk (RR) were 13.12 and 25.90, respectively, both P < 0.05\] and for OS (RR were 3.71 and 3.01, respectively, both P < 0.05). The DFS rate was significantly lower in HD CD3(+)CD4(+) T cells groups than in LD groups (P < 0.05). Multivariate analyses showed that CD3(+)CD4(+) cells dose in grafts was a significant risk factor for DFS (RR = 6.91, P = 0.011).

CONCLUSIONSHigh dose CD34(+) cells in grafts significantly accelerate hematopoietic reconstitution. Transfusion of high doses CD3(+)CD4(+) and CD3(+)CD8(+) cells increases TRM, but decrease OS or DFS.

Syphilis, a chronic bacterial infection caused by the spirochete Treponema pallidum subsp. pallidum, remains a public health concern worldwide. Syphilis control is largely dependent upon early identification and prompt treatment. The diagnosis of syphilis is mainly based on laboratory tests, especially serology and dark-field microscopy. In recent years, recombinant Treponema pallidum antigen-based rapid tests, polymerase chain reaction, and immunoglobulin M antibody detection have also shown certain sensitivities and specificities for syphilitic patients at different stages.
