Objective To describe the hemodynamic characteristics of normal pancreas and pancreatic tumors by 64 slices helical CT perfusion imaging, to evaluate the role of CT perfusion in the diagnosis of pancreatic tumors. Methods Perfusion CT scan was performed in 149 patients, including 36 patients with normal pancreas, 105 patients with pancreatic tumors and 8 patients with duodenal papillary carcinoma. The parameters including blood flow (BF) ,blood volume (BV) and permeability surface area product (PS) were measured. Results The mean value of BF, BV and PS of normal pancreas were (135.24±48.36) ml· min-1·kg-1, (200.55±54.96)ml/kg and (49.75±24.27) ml·min-1·kg-1, respectively. Pancreatic carcinoma has a lower BF, BV and PS,whieh were 31.77±19.36 ml·min-1· kg-1, (66.84±39.49)ml/kg and (37.64±27.14) ml·min-1·kg-1, respectively. The aforementioned parameters in pancreatic cysts were close to zero. The parameters in pancreatic carcinoma were significantly lower than those in normal pancreas(P<0.05); the BF and BV in duodenal papillary carcinoma were significantly lower than those in normal pancreas(P<0.05), while the value of PS was not significantly different from that in normal pancreas; the aforementioned parameters in pancreatic cysts were significantly different from those in normal pancreas(P <0.01). Conclusions In perfu sion CT, normal pancreas was an organ with symmetrical BF,BV and PS. Pancreatic carcinoma was a tumor with low perfusion and decreased PS. Duodenal papillary carcinoma had decreased BF and BV with no significant change in PS. Pancreatic cyst had no blood perfusion. The 64 slice helical CT peffusion imaging was invaluable in differential diagnosis of pancreatic tumors.

Objective: To compare the inhibitory effect of carmustine(BCNU) and bleomycin on craniopharyngiomas in vitro. Methods: Cells were successfully cultured in vitro from the fresh specimens, then the culture medium with bleomycin or BCNU at different concentration was added. The tumor inhibitory curve-line was drawn based on the cell number at different time points. After cultured for 144 h, ATP-luminescence assay was applied to test the antitumor effect. Results: The cell number decreased rapidly when the medium was added. The decreasing speed was faster in BCNU medium than that in bleomycin medium at the same concentration. The bleomycin medium showed no significant inhibitory effect except for the one at 1.00 g/L. However, regardless of the concentration, BCNU medium inhibited the cells effectively. Conclusion: BCNU has stronger inhibitory effect on craniopharyngiomas cells than bleomycin, it can be used to treat this tumor

Objective To confirm the correlation between pre or post processing semen parameters and clinical pregnancy rate in infertile couples with male factors undergoing intrauterine insemination (IUI) .Methods The pregnancy rate based on ovulation in‐ducing agent in infertile couples with male factors infertility per the 2010 world health organization criteria treated with IUI was e‐valuated .One hundred and twenty eight cycles were divided into pregnant group (16 cycles) and non‐pregnant group(112 cycles) . The pre or post processing semen parameters were retrospectively evaluated .Results The overall pregnancy rate was 12 .5% .All parameters in this study has no statistically significant difference between the two groups (P>0 .05) .Logistic multivariate analysis showed that there was no significant correlation between semen parameters and clinical pregnancy rate (P> 0 .05) .Conclusion There are no significant correlations between semen parameters and clinical pregnancy rate when the normal forms of patients with male infertility was 4% or higher .No semen parameters could predict results of clinical pregnancy .

Objective:
To explore the effect of applying the digital technology in the reconstruction of congenital microtia.
Methods:
CT data of 40 patients with congenital microtia were collected by using software (Mimics 17.01) and three-dimensional printing. And the three-dimensional reconstruction of costal cartilage and ear model was performed. The effectiveness and feasibility of the digital assisted technology in the reconstruction of congenital microtia could be established, by contrasting the pre-three-dimensional reconstruction and the morphology of the costal cartilage harvested during surgery and comparing the imaging data of the auricles before and after surgery.
Results:
40 patients were satisfied with the appearance of the auricle after the restoration. The rib cartilage obtained during the operation was consistent with the preoperative data simulation. The trauma of the operation and the operation time were reduced. There was no statistically significant difference between both auricle length and width for the reconstructed ear and those of the normal ear, auricle length mean (62.10±6.82)mm vs (60.31±6.18)mm, auricle width mean (26.10±2.26)mm vs (25.40±2.32)mm,

Objective:
To explore procedure of the one-stage surgery with prolonged tissue expansion in microtia reconstruction and treatment of related complications.
Methods:
211 patients had undergone the one-stage surgery of microtia reconstruction with prolonged tissue expansion in Department of Aesthetic Plastic and Maxillofacial Surgery, the First Affiliated Hospital of Xi′an Jiaotong University from June 2016 to June 2017. A retrospective study of these data was conducted for standardization of surgical procedure, treatment of postoperative complications, improvement of the existing technology.
Results:
211 patients had finished the follow-up, of which 10 had complications. The complications included 4 cases of hematomas, 3 cases of expander exposures, 2 infections, and disorder on blood supply of the flap with severe headache in 1 case. We removed hematoma by washing and drainage, repositioned the exposed expander by standard debridement surgery again, controlled infection by systemic or topical application of effective antibiotics, andrelieved severe headache by reducing injection volume. After these treatments, all the patients were able to undergo the next stage surgery of ear reconstruction.
Conclusions
Emphasizing standardization of surgical procedure, appropriate treatment of postoperative complications and improvement of tissue expansion was beneficial for performing the next stage surgery of ear reconstruction.

Objective:To explore the pathogenesis of primary hemophagocytic syndrome with UNC13D and MYO5A gene mutations.Methods:A case of adult hemophagocytic syndrome with gene mutation of UNC13D and MYO5A admitted to The 940th Hospital of the Joint Logistic Support Force of the PLA on January 28, 2022 was retrospectively analyzed in terms of laboratory examination, gene atlas of its close relatives and prognosis, and related literature was reviewed.Results:The patient was finally diagnosed with primary hemophagocytic syndrome, and chemotherapy was performed twice with hemophagocytic lymphohistiocytosis(HLH)-2004 regimen. The HLA matching of his cytoplasm was semi-compatible. Considering that his cytoplasm carried blood-macrophage related genes, it was not suitable to be selected as a donor, and there were no other suitable relatives. He was transferred to another hospital for allogeneic hematopoietic stem cell transplantation, but failed to receive allogeneic hematopoietic stem cell transplantation during telephone follow-up, and died.Conclusion:The gene mutation of primary hemophagocytic syndrome is the gold standard for the diagnosis of primary HLH. There may be dual gene inheritance pattern in primary HLH, and the combination of immune disorder caused by viral infection and genetic factors may lead to the pathogenesis of primary HLH.
