OBJECTIVE:To investigate the effect of rapid rehabilitation surgery assisted to fluorouracil,oxaliplatin,leucovo-rin(FOLFOX)on postoperative recovery,complications and quality of life in patients with colorectal cancer. METHODS:60 pa-tients with colorectal cancer were randomly divided into control group(30 cases)and observation group(30 cases). After resection of colorectal cancer,control group received 85 mg/m2 Oxaliplatin for injection,2 h intravenous infusion,d1+200 mg/m2 Calcium le-vofolinate for injection,intravenous infusion,once a day,d1-2+400 mg/m2 Fluorouracil injection,intravenous infusion,once a day, d1-5 then 600 mg/m2 for 22 h intravenous infusion,d1-2. Observation was additionally given rapid rehabilitation surgery. 2-week was regarded as 1 course,it lasted 12 courses. Urinary retention time,anal exhaust time,first defecation time,postoperative hospital-ization time,scores of life quality (overall health,emotional function,mental health,physiological functions,physical function,so-matic pain,vitality,social function)in 2 groups were observed,and the incidence of postoperative complications was recorded. RE-SULTS:The urinary retention time,anal exhaust time,first defecation time,postoperative hospitalization time in observation group were significantly shorter than control group,the incidence of postoperative complications in observation group was signifi-cantly lower than control group,overall health,emotional function and mental health score were significantly higher than control group,the differences were statistically significant(P<0.05),but there were no significant differences in physiological functions, physical function,somatic pain,vitality,social function score in 2 groups (P>0.05). CONCLUSIONS:Rapid rehabilitation sur-gery assisted to FOLFOX chemotherapy can reduce the incidence of postoperative complications in patients with colorectal cancer, improve quality of life,shorten hospitalization time and promote postoperative recovery.

ObjectiveTo explore the expression of hemopoietin(EPO) mRNA on cerebral ischemia-reperfusion injury in rats brain tissue and the effect of Tongxinluo on it.Methods The model of rat (MCAO) were perfused with Tongxinluo,the changes of neural stem cell proliferation and differentiation related cell factors of EPO mRNA were detected after ischemia-reperfusion injury 3、5、7、14 d by means of reverse transcriptase polymerase chain reaction(RT-PCR).ResultsEPO mRNA of ischemia-reperfusion models showed expression in different period,the expression enhanced in the third day,reached the highest in the fifth day; the ischemia side EPO mRNA expression enhanced in the third day after give Tongxinluo,in the 5,7 and 14 day,PCR expression gray values were higher than the model group.ConclusionEPO mRNA expression enhanced after cerebral ischemia,this expression can be strengthened by Tongxinluo,and may further induce neural stem cell proliferation and differentiation.

【Objective】 To compare the supply data of red blood cells(RBCs) from 18 blood centers in China before and after the outbreak of COVID-19 during 2018 to 2021. 【Methods】 Eight indicators related to RBCs supply from 18 blood centers in China during 2018-2021 were collected retrospectively, including the storage of total amount of qualified RBCs (referred to as the total amount of storage), the distribution of total amount of RBCs (referred to as the total amount of distribution), the distribution amount of RBCs per 1 000 population (referred to as the amount of distribution per 1 000 population), the distribution amount of RBCs from 400 mL original blood per 1 000 population [referred to as the amount of distribution per 1 000 population (400 mL)], the average daily distribution amount of RBCs (referred to as the average daily distribution amount), the average daily storage amount of RBCs (referred to as the average daily storage amount), the average storage days of RBCs when distribute (referred to as the RBC storage days), and the expired amount of RBCs (referred to as the expired amount). Based on the outbreak time of COVID-19, the data of 2018 and 2019 were the pre-pandemic group, and the data of 2020 and 2021 were the post-pandemic group. 【Results】 Data on RBCs supply in 18 blood centers from 2018 to 2021(comparison of the pre-pandemic group and the post-pandemic group): the amount of distribution per 1 000 population (median 14.68 U>13.92 U) decreased, the amount of distribution per 1 000 population (400 mL) (median 10.16 U>9.21 U) decreased, and the difference was statistically significant (P<0.05); data comparison between 2019 and 2020:the total amount of distribution (median 117 770.38 U>99 084.08 U) decreased, the amount of distribution per 1 000 population (median 15.04 U>12.19 U) decreased, the amount of distribution per 1000 population (400 mL) (median 10.11 U>8.94 U), the average daily distribution amount(322.66 U>270.73 U) decreased and RBC storage days (median 10.50 d<11.45 d) increased, the difference has statistical significance (P<0.05); data comparison between 2020 and 2021:the total amount of storage (median 101 920.25 U<120 328.63 U), the total amount of distribution (median 99 084.08 U<118 428.62 U), the amount of distribution per 1 000 population (median 12.19 U<15.00 U), the amount of distribution per 1 000 population (400 mL) (median 8.94 U<9.46 U), the average daily distribution amount (270.73 U>324.46 U), the average daily inventory (median 3 222.00 U<4 328.00 U) increased, the expired amount (median 1.50 U>0.00 U) decreased, the difference has statistical significance (P<0.05). The results of ANOVA showed that there were significant differences on the data related to RBCs supply (except expired amount) in different blood centers (P<0.05). The ratio of average daily stock to average daily distribution in the post-outbreak group (median 12.36 d) was higher than that in the pre-outbreak group (median 10.92 d), the difference has statistical significance (P<0.05), with significant difference among different blood centers (P <0.05). 【Conclusion】 The COVID-19 pandemic has a significant impact on RBCs supply in different blood centers. In the second year of the pandemic, the supply capability had recovered to some extent, and there were differences in RBCs supply in different blood centers.
