Objective To investigate the long-term curative effect of the radiotherapy combined uterine arterial interventional chemoembolization for cervical cancer.Methods Records of 632 patients with cervical cancer stage Ⅱ-Ⅳa proved by pathology in Lanzhou Command General Hospital from January 1st,1999 to August 31st.2009 were retrospective analysed.One hundrand and twenty-six cases of them were treated with radical radiothempy combined uterine arterial interventional chemoembolization(arterial chemoembolization+radiotherapy group).506 cases of them were treated with radical radiotherapy only (radiotherapy group);the evaluation of the late radiation injury was done,according to Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer(RTOG/EORTC)advanced radiation injury criteria.Prognosis and complications were compared between two groups,relative risk factors of radiothempy complications were identified by method of logistic regression.Results (1)Survival:the total survival mtes of 1-year,2-year,5-year and 8-year were 94.4%,82.3%,48.8%,29.1%,respectively.The survival rates of arterial chemoembolization+radiotherapy group were 96.0%.82.1%,37.2%,25.7%,while the survival rates of radiotherapy group were 94.1%,80.8%,51.1%,31.5%,in which there were significant differences between two groups (x2 = 0.009, P= 0.993; x2 =0. 158, P =0.691;X2 =11. 197,P=0. 001;x2 =9. 649,P =0.002). During the follow-up period, the rate of recurrence and metastasis in arterial chemoembolization + radiotherapy group were 77. 0% (97/126), while 73. 3% (371/ 506) in radiotherapy group ( x2 = 0. 705,P = 0. 401). (2) Radiotherapy complications and relative risk factors; the total incidence of tardive bladder injury higher than RTOG/EORTC stage II was 5.5% (35/632), while it was 11. l%(14/126)in arterial chemoembolization + radiotherapy group, 4.2% (21/506) in the radiotherapy group(x2 =9.344,P =0.002). The results of logistic regression showed that the uterine arterial interventional chemoembolization was relative risk factors of the tardive bladder injury ( x2 =6. 440, OR = 2. 869,P=0. 011). Conclusions Compared with the simple radiotherapy, there are a similar short-term survival rate and significant poor 5-year, 8-year survival rate in the patients treated with the uterine arterial interventional chemoembolization combined with radiotherapy, which also may be strong dangerous factor for the occurrence of tardive bladder injury. The results shown that the uterine arterial interventional chemoem bolization do not recommend to be routine adjuvant therapy for the radical radiotherapy of cervical cancer.

BACKGROUND: Qiangji jianli liquid plays a key role in prevention and cure of myasthenia gravis; however, whether changes of nucleic acid and protein are related to its mechanism or not should be studied further.OBJECTIVE: To observe the effect of qiangji jianli liquid on synthesis of nucleic acid and protein in mice with experimental spleen deficiency syndrome, and investigate the effect on myasthenia gravis and the molecular biological basis.DESIGN: Randomized controlled animal study.SETTING: Testing Center and Basic Medical College of Guangzhou University of Traditional Chinese Medicine.MATERIALS: Healthy male NIH mice, aged 4 weeks, of clean grade, weighing 17-21 g, were provided by Medical Experimental Animal Center of Guangdong Province. Qiangji jianli liquid (Guangdong Dongfang Shencao Pharmaceutical Factory); serpate solution (Guangdong Bangmin Pharmaceutical Factory); [5-methyl-3H] TdR, [5-3H] uridine and L-[4,5-3H]leucine (Atom High-nuclear Technology Application Limited Company).METHODS: The experiment was carried out in the Laboratory of Nuclear Medicine of Guangzhou University of Traditional Chinese Medicine from June to November 2005. A total of 180 healthy male NIH mice were randomly divided into normal control group, model group, 26 g/kg qiangji jianli liquid group, 13 g/kg qiangjijianli liquid group and sijunzi decoction group with 36 in each group. Except normal control group, serpate was used to establish animal models of spleen deficiency syndrome. 0.2 mg/(kg ·d) serpate was intraperitoneally injected into mice. ① 0.1 mL/(mouse·d) saline was intraperitoneally injected into mice in normal control group. ② 26 g/kg and 13 g/kg were perfused into mice in 26 g/kg and 13 g/kg qiangji jianli liquid groups, respectively, once a day. Qiangji jianli liquid consisted of beiqi, dangshen, shengma,baizhu, gaicao, etc., with 1.204 g raw drugs a milliliter. ③ 26 g/kg sijunzi decoction, which consisted of dangshen,baizhu, fuling, jiugancao, etc., was perfused into mice with the dosage of 0.5 mL/mouse in si junzi decoction group once a day. After 16 successive days, contents of DNA, RNA and protein were measured in spleen and kidney tissue; meanwhile, body mass, ratio between spleen mass and body mass, and ratio between kidney mass and body mass were also measured before modeling and after administration.MAIN OUTCOME MEASURES: ① Changes of body mass before modeling and at 16 days after administration; ② changes of mass of spleen and kidney tissues; ③ Comparisons of DNA, RNA and protein in spleen and kidney tissues at 16 days after administration.RESULTS: All 180 mice were involved in the final analysis without any loss. ① There was no significant difference of body mass (17.4-21 g) among groups before experiment (P =0.993); however, after experiment, body mass in model group was lower than that in normal control group (Q =22.84, P ＜ 0.01); 16 days after administration, body mass was higher in qiangji jianli liquid groups (26 g/kg, 13 g/kg) and sijunzi decoction group than that in model group (Q =8.66-10.24, P ＜ 0.01). ② Values of spleen mass/body mass and kidney mass/body mass were decreased in model group as compared with those in normal control group (Q =4.02-12.93, P ＜ 0.01); masses of spleen and kidney tissues were increased in qiangji jianli liquid groups (26 g/kg, 13 g/kg) and sijunzi decoction group as compared with those in model group (Q =3.21-9.69, P ＜ 0.05-0.01); ratios in 13 g/kg qiangji jianli liquid group were higher than those in model group (Q =4.07, 5.92; P ＜ 0.05, 0.01). ③ Contents of DNA, RNA and protein in spleen tissue and contents of RNA and protein in kidney tissue were lower in model group than those in normal control group (Q =7.15-19.2, P＜ 0.01); however, content of DNA in kidney tissue was higher in model group than that in normal control group (Q =4.19, P ＜ 0.05). Contents of DNA, RNA and protein in spleen tissue and contents of RNA and protein in kidney tissue were higher in 26 g/kg qiangji jianli liquid group and sijunzi decoction group than those in model group (Q =2.91-14.12, P ＜ 0.05-0.01 ).CONCLUSION: Qiangji jianli liquid can accelerate synthesis of nucleic acid and protein; additionally, onset of spleen deficiency syndrome may be related to decreasing synthesis of nucleic acid and protein.

【Objective】 To analyze and master the serological and genetic characteristics of the samples with CisAB subtype and their genetic background. 【Methods】 From January 2018 to January 2022, blood samples with discrepant ABO blood typing results, from Zhengzhou voluntary blood donors and hospital patients, were subjected to phenotypic classification using micro column gel card and tube method, as well as amplification of exons 6 and 7 in ABO gene using PCR. The pedigrees of individuals with the same CisAB subtype but different serological typing results in the same family were analyzed. 【Results】 11 The forward typing of 12 samples was AB type, and unexpected antibodies against weaker antigens were found in 11 serum samples, including 9 cases with strong antigen A, 2 cases with strong antigen B, and 1 case with consistent forward and reverse typing results. Gene sequencing confirmed that 11 cases were CisAB01 subtype and 1 case was CisAB05 subtype.Among them, 7 cases had the genotype of CisAB01/O and serological phenotype of A2B3; 2 cases had the genotype of CisAB01/B and phenotype of A2B; 2 cases had the genotype of CisAB01/A and serological phenotype of A1Bx and A1B3; 1 case had the phenotype of AxB. In the CisAB01 family, 1 case of CisAB01/O with A2B3 phenotype and 1 case of CisAB01/B with A2B phenotype were detected. In the CisAB05 family, 2 CisAB05/O01 and 1 CisAB05/O02 were detected. 【Conclusion】 The serological phenotypes of different individuals in the same CisAB01 family can be different when paired with different ABO alleles. It is advisable to accurately identify the CisAB subtype genes with molecular biological methods to ensure blood transfusion safety.

【Objective】 To carry out serological and molecular biological identification of B (A) subtype, and discuss the rational blood transfusion strategy. 【Methods】 Serological and direct sequencing methods were used to detect serotype and genotype of 7 cases of B (A) subtype, and cross matching was performed by saline medium and anti human globulin card to analyze the red blood cells(RBCs) transfusion strategy. 【Results】 The serology results of blood type of 7 samples were similar, with B(A)04/O01 in 3 cases, B(A)04/O02 in 2 cases and B(A)02/O01 in 2 cases. 7 cases of B (A) subtypes were matched with randomly selected blood donors of type O and B on the major side. 【Conclusion】 B(A) subtypes should be identified by genotyping techniques. Washed RBCs of type B and O can be used for B(A) blood type transfusion.

Type 2 diabetes (T2D) is characterized by the malfunction of pancreatic β cells. Susceptibility and pathogenesis of T2D can be affected by multiple factors, including sex differences. However, the mechanisms underlying sex differences in T2D susceptibility and pathogenesis remain unclear. Using single-cell RNA sequencing (scRNA-seq), we demonstrate the presence of sexually dimorphic transcriptomes in mouse β cells. Using a high-fat diet-induced T2D mouse model, we identified sex-dependent T2D altered genes, suggesting sex-based differences in the pathological mechanisms of T2D. Furthermore, based on islet transplantation experiments, we found that compared to mice with sex-matched islet transplants, sex-mismatched islet transplants in healthy mice showed down-regulation of genes involved in the longevity regulating pathway of β cells. Moreover, the diabetic mice with sex-mismatched islet transplants showed impaired glucose tolerance. These data suggest sexual dimorphism in T2D pathogenicity, indicating that sex should be considered when treating T2D. We hope that our findings could provide new insights for the development of precision medicine in T2D.
