OBJECTIVE To observe the clinical efficacy and safety of camrelizumab combined with sorafenib in the treatment of advanced liver cancer. METHODS Sixty patients with advanced liver cancer who were treated in our hospital from March 2020 to November 2021 were selected as the study subjects， and then were randomly divided into study group and control group， with 30 cases in each group. The control group was treated with Sorafenib tosylate tablets orally （0.4 g，bid）， and the study group was additionally given Camrelizumab for injection intravenously （200 mg， every 3 weeks） based on the control group； for all patients， the treatment was stopped until disease progression or intolerable side effects occurred. The clinical efficacy， progression-free survival （PFS）， total survival （OS） and 1-year survival rate of the two groups were compared， and the incidence of adverse reactions in two groups， and immune-related adverse reactions in the study group during treatment were recorded. RESULTS The objective remission rate of the study group was significantly higher than the control group （36.7% vs. 13.3%， P＜0.05）， and the median OS and median PFS were significantly longer than the control group （OS： 12.6 months vs. 7.9 months； PFS： 8.2 months vs. 5.3 months， P＜0.05）. There was no significant difference in the 1-year survival rate and the incidence of elevated aspartate aminotransferase and alanine aminotransferase， rash or pruritus， anorexia， diarrhea， fatigue and hypertension between the two groups （P＞0.05）. The adverse events immune-related in the study group mainly included 21 cases of reactive capillary hyperplasia （70.0%）， 6 cases of hypothyroidism （20.0%）， and 1 case of immune-associated pneumonia （3.3%）， which were improved or tolerable after symptomatic treatment. CONCLUSIONS Camrelizumab combined with sorafenib in the treatment of advanced liver cancer can effectively control and delay the disease progression， prolong the survival period of patients， and the adverse reactions can be tolerated.

【Objective】 To investigate the gene frequency and polymorphism of RBC blood group systems in RhD negtive population in Hunan, so as to lay a foundation for clinical blood transfusion and construction of multiple rare blood group database. 【Methods】 Blood samples were taken from 300 RhD negative blood donors, confirmed by serological method, from June 2019 to June 2020,. RHD genotyping was performed by SSP-PCR. For blood donors with typing results as RhD negative plus RHD gene deletion, antigens genotyping of MNS, Duffy, Kell, Domrock, Diego, Kidd, Sciawnna, Colton, Lutheran and Yt RBC blood group systems were performed by SSP-PCR and analyzed by the chi square test of SPSS 20 statistical software. 【Results】 RHD gene deletions accounted for 58.67% (176 / 300) of serological D negative blood donors. The gene frequencies were as follows: MNS: GYPB^*S=0.045 5(8/176), GYPB^*s=0.954 5(168/176), GYP^*Dane=0.039 8(7/176); Duffy: FY^*A =0.965 6(170/176), FY^*B=0.034 1(6/176); Dombrock: DO^*A=0.082 4(14.5/176), DO^*B=0.917 6(161.5/176); Diego: DI^*A=0.025 6(4.5/176), DI^*B =0.974 4(171.5/176); Kidd: JK^*A=0.485 8(85.5/176), JK^*B=0.514 2(90.5/176); Kell: KP^*A=0.005 7(1/176), KP^*B=0.994 3(175/176); Lutheran: LU^*A=0.005 7(1/176), LU^*B=0.994 3(175/176); Yt: YT^*A=0.002 8(0.5/176), YT^*B=0.997 2(175.5/176). The genotypes of Kell(K+ /k+ ), Scianna and Colton blood groups were KEL^*02 /KEL^*02, SC^*01 /SC^*01 and CO^*A /CO^*B, respectively. The expected frequencies of the combination of type O, RhD negative and other blood group systems were between 1/100 000 to 1/10 000. 【Conclusion】 Among RhD negative blood donors in Hunan, the gene profiles of MNS, Duffy, Domrock, Diego, Kidd, Kell and Lutheran blood group system were polymorphic, and Kell (K+ /k+ ), Colton and Scianna were homozygous. The data of other RBC blood group systems from RhD negative blood donors is of great significance to establish local database of rare blood groups.

Idiopathic pulmonary fibrosis (IPF) is a chronic interstitial pneumonia characterized by progressive accumulation of fibroblastic foci and destruction of the alveolar structure. Due to an incomplete understanding of the mechanism of the occurrence and progression of IPF, currently no effective means have been available for its early screening or treatment. With a poor overall prognosis, the patients with IPF have a median survival of only 2-4 years. In recent years, several studies have confirmed that dozens of molecules are involved in the development of IPF and can be used as potential biomarkers. These biomarkers play important roles in early diagnosis (such as SP-D, MMP-7, and osteopontin), prognostic evaluation (such as telomerase length, KL-6, mtDNA, HSP-70, LOXL2, CXCL13, miRNA, ICAM-1, and CCL18), and guiding treatment of IPF (such as TOLLIP rs3750920 genotype, SAMS score, and SP-D), and also provide potential therapeutic targets (such as TERT, TERR, RTEC, and PARN).

Microtubule inhibitor has been a hot area of anticancer drugs research.Microtubule inhibitor exert an anti-tumor effect by promoting or inhibiting the microtubule aggregation to break the dynamic balance of microtubule,hindering the spindle forma-tion of tumor cells,and then blocking the process of cell divi-sion.Mitotic catastrophe is a cell death phenomenon that is caused by abnormal cell division and damage of spindle structure in cell mitosis phase.In recent years more and more attention has been paid to mitotic catastrophe cell death because it has
been confirmed clinically that microtubule inhibitors can induce mitotic catastrophe death of tumor cells.This paper reviews the latest research progress of microtubule inhibitors,and discusses the molecular mechanisms of mitotic catastrophe cell death tumor cells induced by microtubule inhibitors.

Objective To analyze the curative effect of adult urethrocutaneous fistula after hypospadias repair with X-V dartos flap technique.Methods In the experimental group,the closed fistulas were wrapped with X-V dartos flap in the 22 cases of adult hypospedias fistulas from February 2007 to October 2010.In the control group,the routine fistulas repairs were preformed in the 35 cases of adult hypospadias fistulas from January 2000 to January 2007.The operative effects were compared between the two groups.Results All cases were followed up for 3-49(5.6±12.0)months,no fistula was found in the experimental group,while 7 fistulas(20.0%,7/35)were found in the control group.The fistulas rate had statistic difference between the two groupe(P<0.05).Conclusion The use of the X-V dartos flap technique can prevent adult urethroeutaneous fistula after failed hypospadias fistulas repair and raise the success rate.

Objective To study the anti-tumor effects of humulon on arylamine N-acetyltransferase-1(NAT1)activity.Methods Employing HPLC,using PABA as substrate,in intact SGC-7901 cells and their cytoplasm,making PABA being acetylated to Ac-PABA by NAT1 as the activity of NAT1.Reverse transcriptase polymerase chain reaction(RT-PCR)assay was used to study the expression of the NAT1 mRNA.Results The results show that humulon could inhibit the production of Ac-PABA in intact SGC-7901 cell and the cytoplasm,the production of Ac-PABA was gradually increased with the interaction time increasing.But comparing with corresponding negative control group's,the production of Ac-PABA was decreased evidently and the humulone could inhibit the expression of NAT1 mRNA.Conclusion Humulon could prevent the occurrence and deterioration of cancer.Its mechanisms can be attributed to its effect on decreasing the production of acetylation of carcinogenic aromatic amines,which is acetylated from aromatic amines,and inhibiting the NAT1 activity and expression of NAT1 mRNA.
