ABSTRACT
Objective:To investigate the clinical efficacy and adverse reactions of pemetrexed disodium in the maintenance treatment of advanced lung adenocarcinoma after chemotherapy with pemetrexed disodium and platinum.Methods:The clinical data of 35 patients with stage Ⅳ lung adenocarcinoma who received chemotherapy with pemetrexed disodium and platinum and were well treated in Beijing Huairou Hospital from January 2013 to August 2020 were retrospectively analyzed. Maintenance therapy with pemetrexed disodium was initiated after the completion of combination chemotherapy until disease progression. The clinical characteristics, therapeutic effects, adverse reactions, progression-free survival, and overall survival of the 35 patients were evaluated.Results:Among the 35 patients, no patients had complete remission, 11 patients had partial remission, 22 patients had stable disease, and 2 patients had progressive disease. The objective remission rate was 31.4%, disease control rate was 94.3%, median progression-free survival was 9.53 months, median overall survival was 18.21 months, 1-year survival rate was 68.6%, 2-year survival rate was 31.4%, and 3-year survival rate was 11.4%. Gender, age, smoking, and the baseline characteristics of patients undergoing first-line pemetrexed disodium or second-line pemetrexed disodium treatment had no effects on progression-free survival (all P > 0.05). Positive gene mutation and receiving four or more chemotherapy cycles had a protective effect on progression-free survival (both P < 0.05). Chemotherapy-related adverse reactions mainly included myelosuppression, nausea, elevated transaminase, and nephrotoxicity, all of which were mild and were relieved after symptomatic treatment. Conclusion:Pemetrexed disodium is effective and safe in the maintenance treatment of advanced lung adenocarcinoma. The results of this study are scientific.
ABSTRACT
Objective:To investigate the effects of self-made Hezhong-Jianpi Decoction on gastrointestinal motility and level of inflammatory cell factors in patients with reflux esophagitis. Methods:A total of 102 patients with reflux esophagitis who met the inclusion criteria in our hospital from May 2016 to September 2018 were divided into two group according to the random number table method, 51 cases in each group. The control group was treated with conventional western medicine. The intervention group was treated with self-made Hezhong-Jianpi Decoction based on the control group. Both groups were treated for 8 weeks. The levels of serum gastrin (GAS) and motilin (MTL) were detected by radioimmunoassay, the levels of TNF-α, IL-6 and IL-17 were detected by ELISA, the adverse reactions during the treatment were recorded, and the clinical efficacy was evaluated. Results:The total effective rate of the experimental group was 92.1% (47/51) and that of the control group was 72.5% (37/51). The difference between the two groups was statistically significant ( χ2=6.746, P=0.009). After the treatment, the levels of serum GAS (152.93 ± 26.85 ng/L vs. 134.30 ± 29.88 ng/L, t=3.312), MTL (291.58 ± 29.75 ng/L vs. 262.40 ± 38.71 ng/L, t=4.268) in the intervention group were significantly higher than those in the control group ( P<0.05), and serum TNF-α, IL-6, IL-17 levels were significantly lower than those in the control group ( t value were 4.653, 5.362, 4.759, respectively, all Ps<0.01). During the treatment, the incidence of adverse reactions was 9.8% (5/51) in the control group and 12.0% (6/51) in the intervention group, and there was no significant difference between the two groups ( χ2=0.102, P=0.750). Conclusions:The self-made Hezhong-Jianpi Decoction combined with the conventional western medicine can promote the gastrointestinal motility of patients with reflux esophagitis, reduce the inflammatory reaction and improve the clinical efficacy.
ABSTRACT
We aimed to identify the effect of positive stool cultures (PSCs) on the clinical outcomes of patients undergoing haploidentical hematopoietic stem cell transplantation (haplo-HSCT) (n = 332). PSCs were observed in 61 patients (PSC group, 18.4%). Enterobacteriaceae in stool specimens was associated with a higher risk of bloodstream infection, and Candida in stool specimens was related to a higher risk of platelet engraftment failure. The cumulative incidence of infection-related mortality 1 year after haplo-HSCT in the PSC group was higher than that of the patients who showed persistently negative stool cultures (NSC group; 19.2% vs. 8.9%, P = 0.017). The probabilities of overall survival (71.4% vs. 83.8%, P = 0.031) and disease-free survival (69.6% vs. 81.0%, P = 0.048) 1 year after haplo-HSCT for the PSC group were significantly lower than those for the NSC group, particularly for patients who had Candida in their stool specimens. In multivariate analysis, Candida in stool specimens significantly increased the risk of mortality and was associated with poorer survival. Our results showed that PSC influenced the clinical outcomes after haplo-HSCT, particularly those who had Candida in their stool specimens.
ABSTRACT
Objective To investigate the relationship between miR-411 and breast cancer,and the expression of miR-411 and its effects and mechanism research on proliferation and metastasis in breast cancer.Methods Real-time polymerase chain reaction (RT-PCR) was used to detect the expression of miR411 in breast cancer cells and tissues.Methyl thiazolyl tetrazolium (MTT),clone formation assay and Transwell assay were used to detect the effect of miR-411 expression on the proliferation,migration and invasion in breast cancer cells.The effect of miR-411 on growth factor receptor-bound protein 2 (GRB2) expression in breast cancer cells was detected by RT-PCR and Western blot.The direct effect of miR-411 target on GRB2 was detected by dual luciferase reporter assay.MTT,clone formation assay and Transwell assay detect the effect of GRB2 expression on the proliferation and invasion in breast cancer cells.Detection the effect high expression of miR-411 on GRB2 downstream signaling pathway related molecules expression in breast cancer cell with Western blot.Results The expression of miR-411 in breast cancer tissues was significantly lower than that in adjacent non-cancerous tissues (P ＜ 0.05).The expression of miR-411 in breast cancer cells SK-BR-3,BT-549 and MDA-MB-231 was significantly lower (P ＜ 0.05).Compared to the negative control group,the transfection of miR-411 mimic inhibited the proliferation,migration and invasion of MDA-MB-231 breast cancer cells (P ＜ 0.05).Targetscan showed that miR-411 could bind to GRB2 3'UTR at position 741-747.Compared with the negative control group,GRB2 3'UTR wild-type plasmid and miR-411 co-transfection reduced the fluorescence activity (P ＜ 0.05).Transfection of siGRB2 significantly reduced the expression of GRB2 protein in MDA-MB-231 breast cancer cells (P ＜ 0.05).Compared to the negative control group,the inhibition of GRB2 expression reduced the proliferation and the number of colony formation of MDA-MB-231 breast cancer cells (P ＜ 0.05).Transwell assay showed that transfection of siGRB2 significantly reduced the number of invasive cells in MDA-MB-231 breast cancer cells (P ＜ 0.05).Conclusions miR-411 is related closely to the occurrence and development of breast cancer,miR-411-GRB2-Ras axis is expected to become a new target for biological treatment of breast cancer.

ABSTRACT
Objective To observe the efficacy and untoward reactions of FOLFOX4 regimen and XELOX regimen in the treatment of patients with advanced colorectal cancer.Methods Fifty four advanced colorectal cancer patients were randomly divided into two groups.Group A (FOLFOX4):28 patients were treated with oxaliplatin 85 mg/m2 on day 1,LV 200 mg/m2 as a 2h infusion followed by bolus 5 -FU 400 mg/m2 and a 24h infusion of 5 -Fu 600 mg/m2 ,repeated for consecutive days every 2 weeks.One cycle was 14 days and efficacy was evaluated after 4 cycles.Group B(XELOX):26 patients were treated with oxaliplation 130mg/m2 on day 1,capecitabine 1 000 mg/m2 orally daily for 14 days.One cycle was 21 or 28 days and efficacy was evaluated after 2 cycles.Efficacy of the two groups was evaluated at 2 cycles.Results All 54 patients were available for evaluating objective response.In A group,the overall response rate was 46.4%,and the overall response rate was 42.3% in B group.The overall response rate of A group was slightly higher than B group,but there was no statistically significant difference(χ2 =0.093,P =0.791 ).Adverse reactions:thrombocytopenia incidence rate and the peripheral nerve toxicity had no significant differences between the two groups(χ2 =0.552,0.108,P =0.550,0.787).The incidence rates of nausea, vomit,diarrhea and leucocytopenia in B group were lower than those in A group(χ2 =9.495,4.862,6.273,P =0.003,0.033,0.108).The incidence rate of hand -foot syndrome was higher in B group than in A group(χ2 =13.389,P =0.000),but the severity was less(grade Ⅰ ~Ⅱ).Conclusion The response rate in the treatment of advanced colorectal cancer was similar between XELOX and FOLFOX4 regiments,but XELOX regiment has the advantages of more convenience,better safety.Thus,XELOX regiment is worth recommending as a first -line therapy for the treatment of patients with advanced colorectal cancer.
ABSTRACT
Objective To investigate the effect of exogenous hydrogen sulfide (H2S) on neuronal apoptosis during focal cerebral ischemia-reperfusion (I/R) in rats.Methods One hundred eight male Sprague-Dawley rats,aged 6-8 weeks,weighing 250-270 g,were randomly divided into 3 groups (n =36 each) using a random number table:control group (group C),I/R group and H2S group.Focal cerebral ischemia was induced by middle cerebral artery occlusion in anesthetized rats.A nylon thread with a rounded tip was inserted into the left internal carotid artery and advanced intracranially to block blood flow into the middle cerebral artery.Middle cerebral artery occlusion was maintained for 90 min followed by reperfusion.In group H2S,0.25％ NaSH (a donor of exogenous H2S) 10 mg/kg was injected intraperitoneally at the onset of reperfusion.The equal volume of normal saline was given in C and I/R groups.At 1,3 and 7 days of reperfusion,neurological deficit was scored,and corner test was performed.Brains were removed for determination of myocardial infarct size,Bax-,Bcl-2-and caspase-3-positive cells,and cell apoptosis.The percentage of myocardial infarct size,rate of Bax-,Bcl-2-and caspase-3-positive cells and apoptosis rate were calculated.Results Compared with group C,the neurological deficit score was significantly decreased,and the corner score,percentage of myocardial infarct size,rate of Bax-,Bcl-2-and caspase-3-positive cells and apoptosis rate were increased at each time point of reperfusion in I/R and H2S groups (P＜0.05).Compared with group I/R,the neurological deficit score and Bcl-2-positive cells were significantly increased,and the corner score,percentage of myocardial infarct size,rate of Bax-and caspase-3-positive cells and apoptosis rate were decreased at each time point of reperfusion in group H2S (P＜0.05).Conclusion The mechanism by which exogenous H2S attenuates focal cerebral I/R is related to inhibition of neuronal apoptosis in rats.
