Objective To investigate the impact of preoperative portal vein thrombosis (PPVT) on living donor liver transplantation (LDLT).Methods In this study,99 patients who underwent LDLT by the same surgical team of Tianjin First Centre Hospital from 2007 to 2011 were retrospectively analyzed.According to whether there was a PPVT,all the patients were divided into PPVT group (26 cases) and non-PPVT group (73 cases).The preoperative risk factors and the impact of PPVT on LDLT and outcomes were analyzed.Results Among 26 PPVT patients there were 23 cases in grade Ⅰ and 3 cases in grade Ⅱ.Splenectomy was found to be an independent risk factor for PPVT (x2 =10.211,P =0.001).PPVT prolonged the anhepatic phase (Z =-2.430,P =0.015),but the incidence of surical complications and mortality were no statistical differences between the PVT group and the non-PVT groups.Meanwhile,there was no statistical difference of 1-and 3-year survival rate between the two groups(x2 =0.505,P =0.477).Conclusions With proper intraoperative treatment and postoperative prevention,PPVT does not affect the outcomes of patients suffering from grade Ⅰ or Ⅱ PPVT.However,PPVT added to difficulties of operation,so the detailed preoperative evaluation and careful intraoperative operation is necessary.

Objective To investigate the serological characteristics and gene mutation mechanism of RhD variant blood donors in Zhengzhou.Methods From January 2023 to December 2023,1 619 RhD-negative blood donors sent to our labora-tory were selected for the study,and RhD negative confirmation test and RhCE phenotype detection were applied by tube method and microcolumn gel indirect antiglobulin test method.RHD gene amplification and Sanger sequencing were used to detect RhD variant sample genotypes.Results A total of 69 cases of RhD variants were detected in the RhD negative con-firmation test,with a proportion of 4.26%(69/1 619).The RhCE phenotypes were ccEe,Ccee,CcEe and CCee.There were 17 genotypes and 15 phenotypes of the D variant.The RHD?weak partial 15 allele was the most frequent(33 cases),with a frequency of 47.83%(33/69),and the main phenotype was the ccEe.This was followed by the RHD?DVI.3 allele in 20 ca-ses with a frequency of 28.99%(20/69)and the predominant phenotype was Ccee.The RHD?weak partial 15/RHD?01EL.01 heterozygote was found in 3 cases with a frequency of 4.35%(3/69),all with the CcEe phenotype.Other rare genotypes were present in 13 cases with a frequency of 18.84%(13/69).Antibody screening was positive in 3 cases with a frequency of 4.35%(3/69).Two cases of female blood donors,both with history of pregnancy and childbirth,were identified as anti-D;one case of male donor was anti-M.Conclusion The RHD?weak partial 15 genotype was the most common among the RhD variants in blood donors in Zhengzhou,followed by the RHD?DVI.3 genotype.It plays an important role in guarantee-ing the safety of blood supply and guiding precision transfusion.

Objective To analyze the application of serological test results in the diagnosis and treatment of anti-M-in-duced hemolytic disease of the fetus and newborn(HDFN),and to explore HDFN prevention strategies.Methods The se-rological test results of 12 cases of HDFN caused by anti-M diagnosed in our laboratory from January 2017 to December 2023 were retrospectively analyzed,including blood group identification of mothers and children,serum total bilirubin/hemoglo-bin/antibody titer test,and three hemolysis tests in newborns.Clinical data of the children and mothers were collected,in-cluding pregnancy history,blood transfusion history,prenatal antibody testing,history of intrauterine blood transfusion and gestational week of delivery,and the prognosis of the children was followed up.Results All 12 cases of fetal neonatal he-molytic disease due to anti-M were RhD+MN phenotype newborn born to RhD+NN mother,with maternal-fetal incompati-blility in MN blood groups.In the ABO blood group system,ABO incompatibility between mother and child accounted for 41.7%(5/12).None of the mothers had a history of blood transfusion,and the median titer of the test at 4℃was 32,and the median titer at 37℃was 4.The mothers of 3 cases had a history of multiple intrauterine blood transfusions,with an inci-dence of 25%(3/12).One case had an abnormal first pregnancy,with an incidence of 8.3%(1/12),and seven cases had an abnormal pregnancy with a miscarriage,with an incidence of abnormal pregnancy and birth history of 58.3%(7/12).There were 6 cases of premature labor,with an incidence of 50%(6/12).The mothers in three cases underwent regular ob-stetric examination and the specificity of the antibodies was determined,accounting for 25%(3/12).Twelve children had free antibodies with a median titer of 6 at 4℃and 2 at 37℃.Two children had anti-M antibodies that were not reactive at 37℃,with a negative rate of 16.7%(2/12).The positive rate of DAT and elution test was respectively 8.3%(1/12)and 16.7%(2/12)in the children.The median minimum hemoglobin value was 75 g/L,and all 12 children received blood transfusions.The median peak total bilirubin value was 157.5 μmol/L,and none of them reached the threshold for blood ex-change.The rate of delayed anemia was16.7%(2/12),the postnatal mortality rate was8.3%(1/12),and 11 children was free of growth and neurodevelopmental delay in prognosis.Conclusion Anti-M can cause severe HDFN,which can also oc-cur in primigravida.The intensity of antibody titer does not correlate with the severity of the disease,and it is prone to cause delayed anemia,which should be monitored regularly according to the serological characteristics of anti-M and clinical symp-toms,and should be treated timely.

To analyze statistically the situation of the National Natural Science Foundation of China (NSFC) from 2007 to 2016 in the field of acupuncture and moxibustion for supporting the national Universities colleges of traditional Chinese medicine on the General Program (GP) and the National Science Fund for Young Scholars (NSFYS). In view of five aspects, named fund, supporting units, key words, method, disorder and signal path, the differences were compared between GP and NSFYS, the following characteristics were summarized. ① The fund aid was increased from 2007 through 2013 and down-regulated from 2013 through 2016. In recent ten years, the funding condition was fluctuated, but increasing in tendency generally. ② The relevant projects of the same research direction had been approved continuously for over 3 years in a part of TCM universities, in which, the research continuity was the hot topic. ③ Regarding the therapeutic methods, acupuncture was the chief therapy; electroacupuncture, moxibustion and acupoints were involved as well. ④ The disorders involved in the research were cerebral ischemia, myocardial ischemia and reperfusion injury. It is suggested that the ischemic disorder is predominated in the research. ⑤ The signal path occupied the main research index system, including cell proliferation, metabolism, immune, apoptosis and autophagy. The researches on the other aspects were less.

[摘 要] 目的：探究益气活血汤对恶性肿瘤患者癌痛及癌因性疲乏（CRF）的疗效。方法: 选取2020年1月至2022年12月间安徽省中医药大学第二附属医院收治的82例确诊发生CRF的恶性肿瘤患者（气血亏虚证），采用随机数字表余数分组法将其分为对照组与观察组，每组各41例。对照组患者采用常规止痛、止吐、化痰等对症治疗及健康、心理指导，观察组患者在对照组干预的基础上联合益气活血汤治疗，4周为1个疗程。治疗前及治疗4周后，对两组患者进行中医证候积分评估，以积分变化评估中医临床疗效；采用修订版Piper疲乏量表（RPFS）评估CRF的改善情况；采用数字疼痛分级法（NRS）评分比较癌痛情况；检测患者外周血纤维蛋白原（FIB）、D-二聚体（D-D）评价凝血功能差异，检测患者肝、肾功能指标以评估益气活血汤治疗的安全性。结果：治疗前，两组患者在中医证候积分、RPFS评分、NRS评分及外周血FIB、D-D方面的差异均无显著统计学意义（均P>0.05）。治疗4周后，两组患者在神疲乏力、面色淡白或萎黄、自汗、失眠健忘、手足麻木的证候评分及总积分均较治疗前明显降低（均P<0.05），且观察组各项评分均低于对照组（均P<0.05），中医临床疗效明显高于对照组（P<0.05）；两组患者RPFS各维度评分及总分均较治疗前降低（均P<0.05），观察组行为、情感、感觉维度RPFS评分及总分均低于对照组（均P<0.05），观察组CRF的改善明显优于对照组（P<0.05）；两组患者NRS评分及外周血FIB、D-D指标均较治疗前降低（均P<0.05），且观察组均低于对照组（均P<0.05）。两组患者治疗期间均未发生肝功能、肾功能等明显异常，说明益气活血汤安全性良好。结论：益气活血汤可纠正气血亏虚之证，改善机体凝血功能，促进恶性肿瘤患者CRF及癌痛的减轻，临床应用价值较高。
