RESUMEN
Objective@#To investigate the incidence and clinical features to probe the risk factors of hemorrhagic cystitis (HC) in children and adolescents with hematological diseases post haplo-hematopoietic stem cell transplantation (haplo-HSCT) .@*Methods@#Medical records of 62 children and 27 adolescents with hematological diseases treated with haplo-HSCT between 2015 and 2016 were analyzed.@*Results@#Of 89 cases (56 boys and 33 girls) , 44 patients were diagnosed with ALL, 33 AML, 3 AHL and 9 MDS. HC occurred in 32 of the 89 patients with an incidence of 36%, including 6 with grade Ⅰ, 16 with grade Ⅱ, 8 with grade Ⅲ, 2 with grade Ⅳ HC, respectively. The median time of HC onset was 25 days (range 2-55 days) after haplo-HSCT with the median duration as 19 days (range 3-95 days) , all of them were cured. The incidence of HC was lower in the group of children than that in the group of adolescents (27.4% vs 55.6%, χ2=6.466, P<0.05) , and the incidence of HC was higher in the group of patients who were ≥5 years old than that in the group of patients who were <5 years old (0 vs 34%, χ2=4.043, P<0.05) .@*Conclusion@#HC is one of common complications in children and adolescents with hematological diseases post haplo-HSCT, older age was associated with increased mortality.

Objective@#To compare the clinical efficacy and safety of bortezomib, cyclophosphamide, dexamethasone (VCD) regimen and bortezomib dexamethasone (VD) regimen in the treatment of the patients with newly diagnosed multiple myeloma (NDMM).@*Methods@#The clinical data of 73 patients with NDMM in Shanxi Dayi Hospital from January 2013 to January 2016 were retrospectively analyzed. According to the chemotherapy regimen, the patients were divided into VCD group (41 cases) and VD group (32 cases). The efficacy and adverse reactions of the two groups were evaluated.@*Results@#The overall response rate of VCD group and VD group was 80.5% (33/41) and 78.1% (25/32) respectively, and the difference was not statistically significant (χ 2= 0.061, P= 0.804); and complete remission (CR) rate was 36.6% (15/41) and 15.6% (5/32) respectively, and the difference was statistically significant (χ 2= 3.970, P= 0.046); the median progression-free survival (PFS) was 27 months and 24 months respectively, and the median overall survival (OS) was 35 months and 33 months respectively, and the differences were not statistically significant (all P > 0.05). Most adverse reactions occurred in grade 1-2, in which peripheral polyneuropathy and thrombocytopenia were the most common. Peripheral neuritis was the most common finding among the adverse reactions of grade 3. The incidence of adverse reactions in both groups was not statistically significant (P > 0.05).@*Conclusions@#VCD and VD regimen could be recommended as a better induction therapy for NDMM patients. Compared with VD scheme, VCD scheme has a higher CR rate.

Objective To explore the effects of modified herringbone-Trendelenburg position during gynecological laparoscopic operation of the elderly. Methods A total of 60 elderly patients undergoing gynecological laparoscopic operation under general anesthesia were recruited and assigned to the observation group (30 cases) and control group (30 cases) by random digits table method with 30 cases each according to admitting time;Patients in the control group were placed in conventional Trendelenburg position, while the patients in the observation group were positioned in modified herringbone-Trendelenburg position .Intraocular pressure (IOP) were measured in the patients at anesthesia induction (T1),5 minutes after general anesthesia in supine position (T2) , and 5 minutes after pneumoperitoneum while in the operation position (T3) , every 30 minutes (times 4 to 11), while supine at the end of pneumoperitoneum (time 12) and before awakening (time 13);Patients were followed up at 24 h and 48 h after surgery, researcher investigate and record the scores of the Operation Position Comfort Questionnaire, the situation of the pain in the shoulder and postoperative complications of the lower limbs. Results There was no statistically significant difference (t=-1.098,-0.772,-0.656, P>0.05) of the IOP at T1, T2, T13. The IOP in the observation group had statistically significant difference compared with the control group at T3 to T12 (t=6.523-19.866, P<0.01). The incidence rate of the postoperative complications of the lower limbs in the observation group was 6.7%(2/30) lower than 26.7%(8/30) of the control group (χ2=4.320, P<0.05) and the VAS scores of the patients in the two groups was statistically significant (t=2.471, P<0.05). The incidence rate of the postoperative shoulder pain in the observation group was 10.0%(3/30) lower than 43.3%(13/30) of the control group (χ2=8.523, P<0.01), and the Visual Analogue Scale scores of the patients in the two groups was statistically significant (t=3.575, P<0.05).The scores of the Operation Position Comfort Questionnaire in the observation group was higher than the control group (t=-2.319, P<0.05). Conclusions Modified herringbone- Trendelenburg position can reduce the elevation of intraocular pressure in elderly patients without affecting the operation ,and effectively improve the comfort of the operation position of the patients, reduce the incidence rate of the shoulder pain and postoperative complications of the lower limbs, is conducive to the operation safety of elderly patients.
RESUMEN
AIM: To investigate the role of fatty acid translocase/CD36 (FAT/CD36) in adipose tissue in-flammation induced by a high-fat diet.METHODS:C57BL/6J mice were fed with a normal-chow diet ( NCD) or a high-fat diet ( HFD) for 14 weeks.The content of free fatty acid ( FFA) in the serum was measured by ELISA.The expression of CD36, cytokines and chemokines at mRNA and protein levels in the adipose tissues was determined by real-time poly-merase chain reaction and Western blotting.Immunohistochemical staining was used to examine the macrophages infiltration in the adipose tissues.The inflammatory responses in CD36 knockout mice and wild type mice with high-fat diet were ana-lyzed.RESULTS:The levels of FAT/CD36 were higher in HFD group than that in NCD group.HFD feeding enhanced the mRNA and protein expression of IL-1β, IL-6, TNF-α, MCP-1 and MIP-1, as well as promoted macrophage infiltration in the adipose tissues.Interestingly, as fed with HFD, the expression of cytokines/chemokines and macrophage infiltration were significantly reduced in adipose tissues of the CD36 knockout mice, compared with the wild type mice.CONCLU-SION:High-fat diet promotes adipose tissue inflammation in the mice in a FAT/CD36-dependent manner.
RESUMEN
Objective To investigate the effect of bortezomib alone and in combination with imatinib on apoptosis of human chronic myeloid leukemia cells of the line K562 ,what is more, to explore the mechanism. Methods K562 was cultured and treated with bortezomib and (or) imatinib in different concentrations for 12, 48, 72 hours. Cell proliferation was analyzed by MTT assay, the apoptosis of K562 cells was observed by flow cytometry, and the expression of Livin mRNA was determined by reverse transcription polymerase chain reaction (RT-PCR). Results MTT assay and flow cytometry showed that bortezomib could inhibit K562 cell proliferation and induce its apoptosis, and it can strengthen cells' lethal effect by imatinib. The expression of Livin mRNA was decreased by bortezomib or imatinib to some extent, and was downregulated significantly when combined treatment was given. Conclusion Bortezomib alone and in combination with imatinib can induce K562 cells apoptosis, in which decrease of the expression of Livin mRNA is the possible mechanism.
