Clinical efficacy of targeted therapy, immunotherapy combined with hepatic artery infusion chemotherapy (FOLFOX), and lipiodol embolization in the treatment of unresectable hepatocarcinoma.

To evaluate the clinical efficacy of targeted therapy and immunotherapy combined with hepatic arterial infusion chemotherapy (HAIC) of FOLFOX and lipiodol embolization in the treatment of unresectable hepatocellular carcinoma. Patients included in the study were those who received targeted therapy and immunotherapy combined with HAIC of FOLFOX and lipiodol embolization in Zhongshan People's Hospital from December 2020 to June 2021 for unresectable hepatocellular carcinoma. Evaluation indicators included objective response rate (ORR), median progression-free survival (mPFS), median duration of response (mDOR), 1-year overall survival rate (OS), surgical conversion rate, and adverse events. Treatment response was assessed using Response Evaluation Criteria in Solid Tumors (mRECIST and RECIST v1.1). A total of 35 patients were included in this study, 30 of whom completed treatment evaluation. According to mRECIST evaluation criteria, the objective response rate (ORR) was 83.3% (25/30); the complete response (CR) was 60% (18/30); the partial response (PR) was 23.3% (7/30), and stable disease (SD) was 16.7% (5/30). The mDOR was 10.3 months (95% Cl: 8.27-NE), and the mPFS was 13.2 months (95% CI: 10.3-NE); the surgical conversion rate was 30.0% (9/30). The 1-year OS was 96.7%. There were no serious surgical complications and grade 4 or 5 adverse events of targeted therapy, immunotherapy and HAIC. Some patients had grade 3 adverse reactions in gastrointestinal toxicity or hepatotoxicity, and the adverse reactions were improved after corresponding symptomatic treatment. We concluded that HAIC of FOLFOX and lipiodol embolization combined with targeted therapy and immunotherapy had a significant curative effect in the treatment of unresectable hepatocellular carcinoma, with no serious adverse reactions and a high rate of surgical conversion rate.

Genetic characteristics of non-Hodgkin lymphoma in ethnic Uighur people, and their clinical significance.

The incidence of non-Hodgkin lymphoma (NHL) in China is increasing and is attracting attention as a topic of research. The percentage of NHL cases in ethnic Uighur people is also gradually increasing. We therefore recruited Uighur people with NHL to investigate the correlation between genetic alternations and clinical/pathological features in an attempt to determine their clinical significance. A total of 60 NHL patients were recruited from our hospital for a microscopic examination of their tumor cell morphology. Further analysis of chromosome karyotypes revealed the relationship between genetic alternations and clinical/pathological features. Microscopic examination revealed increased numbers of tumor cells with altered morphology. The recruited patients all exhibited abnormal karyotypes. Chromosomal breakages were detected at 14q32, 18q21, 6q21-25, +3, +, +18, and short tandem repeat 17 (str17) in 18.3, 25, 25, 18.3, 15, and 21.7% of patients, respectively. Karyotype change was not related to age, gender, performance status score, or pathological type (P > 0.05), but was correlated with clinical stage, average lactate dehydrogenase (LDH) level, extra-lymphatic metastasis, median survival time, and efficacy of radio- or chemotherapy (P < 0.05). Independent risk factors for genetic change in Uighur NHL patients included clinical stage, average LDH level, extra-lymphatic metastasis, median survival time, and efficacy of radio- or chemotherapy (P < 0.05). Uighur NHL patients exhibited genetic changes including t(14:18), 6q21-25, +3, +7, +18, and str17. Clinical stage, average LDH level, extra-lymphatic metastasis, median survival time, and efficacy of radio- or chemotherapy were all independent risk factors for NHL.

[Studies on the early development of nucleocytoplasmic hybrid embryos between mouse and rabbit by nuclear transplantation].

Nuclear transplantation has been proved to be a very powerful method in researching the relationship between nucleus and cytoplasm during embryogenesis. Electrofusion is a new means of cell fusion which is being improved in the past nearly ten years. In this study, we produced interorder nucleocytoplasmic hybrid embryos between mouse and rabbit with these two techniques. Two phenomena, i.e. premature chromosome condensation (PCC) and nuclear swelling, were observed after mouse 8-cell stage blastomeres were fused into rabbit enucleated oocytes. After 4.5-days cultured in mouse oviducts, 5.4% reconstituted embryos developed into blastocysts. By karyotype examination, it was known that only mouse chromosomes were presented in the blastomeres, one blastocyst even had a normal mouse karyotype (2 n = 40, XX). As a conclusion, we consider it is possible to obtain normal early development of interspecies nucleocytoplasmic hybrid embryos between mouse and rabbit.

[Relation among syndrome of spleen deficiency and stagnation of liver-qi and electrogastrogram, gastric mucosal pathology and pulse-cardiovascular function in chronic gastric diseases].

In this research, Syndrome of Deficiency of Spleen (DS) and Stagnation of Liver-Qi (SLQ) as well as observations of electrogastrogram (EGG), gastric mucosal pathology and pulse cardiovascular examination were investigated in 56 cases of chronic gastric diseases (CGD). The results showed: (1) In SLQ with DS the amplitude of EGG was significantly higher than that of the control group (P < 0.01), it often indicated the active period of pathologic change, but in DS with SLQ, the amplitude of EGG was significantly lower than that of the control group (P < 0.01), it frequently denoted the static period. In case that DS equalled to SLQ, the amplitude of EGG was significantly higher than that of the control group (P < 0.01). It revealed that there were no significant difference between the patient's number of static and active periods (P > 0.05). It is valuable in Syndrome Differentiation of Deficiency and Excess and analysis of Superficiality and Origin in CGD. (2) Cardiovascular function was also affected in Syndrome differentiation of DS and SLQ. DS with SLQ manifested itself as reduction of left ventricle pump and declination for metabolism of microcirculation, they had significant difference as compared with the control group (P < 0.05), while SLQ with DS or equality between DS and SLQ had the normal function of left ventricle pump and metabolism of microcirculation, even though cardiac output were higher than that of control group (P < 0.05). It showed that the traditional Chinese medicine theory of interrelation among Heart and Spleen, Liver had their own hemodynamic bases.
