ABSTRACT
OBJECTIVE：To study the effect s of Bifidobacterium combined with L-carnitine on intestinal flora of dysbacteriosis diarrhea model rats. METHODS ：Totally 30 SD rats were randomly divided into blank control group ，model group ，probiotics group（Bifidobacterium triple viable enteric coated capsules 70 mg/mL），L-carnitine group （L-carnitine injection 50 mg/mL）and L-carnitine+probiotics group （L-carnitine injection 50 mg/mL+Bifidobacterium triple viable enteric coated capsules 70 mg/mL）. Except for blank control group ，the rats in other groups were given 50 mg/mL clindamycin phosphate intragastrically （2 mL/rat， once a day ，for 4 consecutive days ）to establish the model of dysbacteriosis diarrhea. On the 5th day of the experiment ，the rats in administration groups were given corresponding drugs intragastrically ，blank control group and model group were given equal volume of normal saline intragastrically ；with the dosage volume of 1 mL/rat，once a day ，for consecutive 7 days. The general situation of rats in each group was observed during the experiment. The feces of normal control group and model group at the end of the modeling and the feces of the rats in administration group after the last administration were collected for genomic DNA extraction，polymerase chain reaction amplification ，library construction and high-throughput sequencing. After processing ，the effective data were analyzed by operational taxonomic unitsclustering and species annotation ，as well as Alpha and Beta diversity of compared with blank control group ，grade 1 feces and grade 2feces were found in model group. The diversity and richness of intestinal flora ，the ratio of Firmicutes/Bacteroidetes and zhongjuanwang7@163.com the abundance of probiotics such as Lactobacillus， Bifidobacterium and Ackermann were significantly decreased （P＜0.05），while the abundance of pathogenic bacteria such as Enterococcus was significantly increased （P＜0.05）. At the end of the recovery period ，compared with model group ，the activity，fecal morphology and color of rats in probiotics group ，L-carnitine group and L-carnitine+probiotics group returned to normal，and the diversity and richness of intestinal flora had no significant difference （P＞0.05）. However ，the abundance of Lactobacillus in intestinal tract was increased to a certain extent ，and the abundance of Ackermann in intestinal tract of rats in L-carnitine+probiotics group was significantly increased （P＜0.05）. CONCLUSIONS ：Although Bifidobacterium combined with L-carnitine have no significant effect on improving the diversity and richness of intestinal flora in dysbacteriosis diarrhea model rats，it could increase the abundance of probiotics to a certain extent.
ABSTRACT
Objective To investigate the clinical features of pulmonary lymphoma and to get a better understanding of this disease. Methods Clinical data of 253 lymphoma patients in the Department of Lymphoma and Hematology in Jilin Cancer Hospital from October 2014 to March 2017 were retrospectively analyzed. The patients were divided into 30 cases of pulmonary lymphoma (lung lymphoma group) and 223 cases of non-pulmonary lymphoma (the control group). Rate assay and latex turbidimetry was used to detect lactic dehydrogenase (LDH) and β2macroglobulin (β2-MG) respectively. The expressions of programmed death 1 (PD-1), programmed death ligand 1 (PD-L1) and cytotoxic T lymphocyte-associated antigen 4 (CTLA-4) in peripheral blood CD4 +CD8 +T lymphocytes were detected by using flow cytometry. The count and measurement data of both groups were compared by using χ 2test and t test respectively. Results The patients in pulmonary lymphoma group showed secondary lesions. The proportion of smoking people in pulmonary lymphoma group was higher than that in the control group [43.3 % (13/30) vs. 24.2 % (54/223), χ 2＝ 4.964, P＝ 0.026]. The proportion of the patients in Ⅲ-Ⅳ stage in pulmonary lymphoma group was higher than that in the control group [93.3 % (28/30) vs. 57.0 % (127/223), χ2＝ 14.750, P < 0.001]. The proportion of the patients with higher international prognostic index (IPI) score in pulmonary lymphoma group was higher than that in the control group (χ2＝ 21.888, P < 0.001). The proportion of the patients with increased expression of β2-MG in pulmonary lymphoma group was higher compared with the control group [66.7 % (20/30) vs. 50.2 % (112/223), χ2＝6.682, P ＝0.091]. The proportion of the patients with the increased LDH was higher compared with the control group [63.3 % (19/30) vs. 41.5 % (86/223)], and the difference was statistically significant (χ2＝ 6.682, P ＝ 0.010). Diffuse large B-cell lymphoma (DLBCL) was the common pathological type in pulmonary lymphoma group (15 cases), followed by Hodgkin lymphoma (7 cases); imaging showed single mass or nodular type, multiple masses or nodular type, bilateral pulmonary infiltration, pleural effusion were 36.7 % (11/30), 30.0 % (9/30), 63.3 % (19/30) and 36.7 % (11/30), respectively. There were no statistical differences in the protein expression of immune check points such as PD-1, PD-L1 and CTLA-4 in both groups (all P ＞ 0.05). Conclusions Pulmonary DLBCL should be considered a secondary disease, but not a primary lesion. Smoking history is a risk factor for lymphoma patients with pulmonary involvement. Pulmonary lymphoma is similar to other extra-nodal lymphoma with high IPI scores, advanced stage and elevated LDH.
ABSTRACT
Objective: Secondary malignancy is a major life-threatening complication facing patients afflicted with acquired immunodeficiency syndrome [AIDS]. This study aimed to retrospectively review clinical features and treatment course of five patients with AIDS-associated non-Hodgkin lymphoma [A-NHL] in Jilin Tumor Hospital
Methods: Five A-NHL patients were retrospectively and consecutively hospitalized at our oncological unit between January 2012 and June 2014. All patients received pre-emptive highly active antiretroviral therapy [HAART] and chemotherapy, and were subsequently followed up at the outpatient clinic. All five patients were male, aged 27-53 years, and afflicted with A-NHL involving upper jaw, right inguinal region, right-side gingiva, mediastinum, or right-side neck. Histology showed diffuse large B-cell lymphoma [n = 3] or plasmablastic lymphoma [n = 2]
Results: Two patients achieved complete remission after HAART and chemotherapy, whereas other three patients required a second-line treatment, with two achieving stable disease and one dying within a follow-up period of 0.5-2 years
Conclusion: The findings of the present study showed that A-NHL is a disease often diagnosed in the middle-to-late stages, with diverse clinical manifestations and short overall survival. In the cases reviewed in this study, HAART in combination with standard dose or high-dose chemotherapy, HAART and molecular targeted chemotherapy was administered, and these treatments proved to be effective for improving the prognosis of these patients. Moreover, the CD4+ cell count was important for determining the prognosis of patients
ABSTRACT
OBJECTIVE:To provide reference for rational drug use in pediatric department. METHODS:The utilization of pe-diatric prescription drugs in inpatient department of our hospital during 2008 to 2014 was analyzed in respects of number,consump-tion sum,DDDs,etc. RESULTS:The consumption sum of antimicrobial drugs increased from 657 000 yuan in 2008 to 1 453 000 yuan in 2014. The consumption sum of creatine phosphate sodium increased from 384 000 yuan in 2012 to 889 000 yuan in 2014. The consumption sum of Lysine hydrochloride and sodium chloride injection entered the top 5 in 2014,reaching 205 000 yuan. The consumption sum of essential medicines changed greatly due to varieties. Top 5 antimicrobial drugs in the list of DDDs mainly wereβ-lactam,showing a descreasing trend on the whole. CONCLUSIONS:There are some problems in use of part drugs. It is need to strengthen propaganda and intervention of rational drug use.
