Objective To discuss the clinical features of HbeAg-negative chronic hepatitis B patients associate with non-alcoholic fatty liver disease (NAFLD), to value the effect of combining treatment on fatty liver influence and antivi-ral therapy. Methods Nighty eight chronic hepatitis B patients with non-alcoholic fatty liver disease (NAFLD) (Liver pa-thology G≥2 or S≥2,HBV DNA>1 × 105 copies/mL), were observed and given antiviral therapy with interferon alpha 1 b for 24 weeks. These patients were divided into combined treatment group (55 cases treated with interferon alpha 1 b combined with Jian Gan Jiang Zhi pills) and control group (43 cases treated with interferon alpha 1 b) in accordance with random num-ber table. All these patients took Leucoson to prevent blood cells reduction. The combined treatment effect was analyzed by observing and comparing biochemical serum change and HBV DNA negative conversion ratio between two groups. Re-sults After 24 weeks of antiviral therapy in Chronic hepatitis B patients with negative HBeAg associated with NAFLD, ALT and AST decreased significantly in both treatment group and control group. And this change is more obvious in treat-ment group than in control group. TC and TG in treatment group and TC in control group were also dropped with treatment (P<0.05). There is significant difference on HBV DNA negative conversion ratio between treatment groupand control group (98.2%vs 86.0%,P<0.05). Conclusion The combination of antiviral treatment and anti fatty liver treatment can obviously improve liver function and blood lipids, increase negative conversion ratio of HBV DNA for chronic hepatitis B patients asso-ciated with NAFLD.

Objective To discuss the method and skill of prenatal diagnosis of fetal isolated pulmonary stenosis and thus to improve prenatal diagnostic ability.

Objective:This study aimed to evaluate the maintenance therapy following an anti-CD19-CAR T-cell therapy for a B-cell acute lymphoblastic leukemia (ALL) patient who relapsed after allogeneic hematopoietic cell transplantation (allo-HSCT) and investigate the effect of donor stem cells and donor T lymphocyte infusion on the amplification of CD19 CAR-T cells.Methods:One refractory B-ALL patient relapsed after murine CD19 CAR-T cell therapy followed by a sibling allo-HSCT. He underwent a humanized CD19 CAR-T cell therapy followed by donor stem cell and donor T lymphocytes infusions as maintenance therapy in our hospital. The level of cytokines, the proportion of CD19 CAR-T cell, the level of CAR19 DNA expression in the peripheral blood, and the proportion of leukemia cells and donor chimerism in the bone marrow were detected. Correspondingly, T lymphocytes from the C57 spleen were separated to modify the CD19 CAR lentivirus and refused into C57 mice, and after 14 days, the B lymphocytes from C57 mice were separated and refused into the same C57 mice. The CD19 CAR T cells, B cells, and CD19 CAR gene counts in the peripheral blood were evaluated at different time points.Results:①The patient achieved a complete response (CR) 14 days after a humanized CD19 CAR-T therapy with grade 1 cytokine release syndrome (CRS) and restored a donor chimerism to 99.76%. ② Following the remission from humanized CD19 CAR-T therapy, the patient received a maintenance therapy of donor stem cell infusion. Mild graft-versus-host disease (GVHD) manifested 24 days after infusion with an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression in the peripheral blood. It fell with the remission of GVHD. The patient maintained CR and 99.69% donor chimerism during this period. ③ Throughout the subsequent donor T lymphocytes maintenance therapy, mild GVHD surfaced12 days after infusion without an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression in the peripheral blood. The patient maintained CR and 99.87% donor chimerism during this period. ④ In vivo experiments on C57 mice confirmed that the proportion of CD19 CAR-T cells and the level of CAR19 DNA expression were upregulated in mice following CAR-T cell infusion, accompanied by depletion of CD19 + B lymphocyte. After infusion of CD19 + B lymphocyte cells, an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression in the peripheral blood were observed again. Conclusions:The infusion of donor stem cells and donor T lymphocytes could be used as a maintenance treatment after CD19 CAR-T cell therapy for B-ALL patients who relapsed after allo-HSCT. Infusion of donor stem cells induced an increased proportion of CD19 CAR-T cells and an increased level of CAR19 DNA expression with the occurrence of GVHD. It might lead to further elimination of minimal residual disease.

Objective To investigate the correlation between insulin resistance and interleukin-6 (IL-6), chemerin, total cholesterol (TC)/high density lipoprotein cholesterol (HDL-C) ratio, triglyceride (TG)/HDL-C ratio, low density lipoprotein cholesterol (LDL-C)/HDL-C ratio and insulin resistance in obese patients with type 2 diabetes mellitus (T2DM), and to provide scientific basis for T2DM prevention and control. Methods A total of 355 obese T2DM patients in Songjiang Hospital Affiliated to Shanghai Jiaotong University School of Medicine were selected from January 2021 to December 2023. IL-6, chemerin and lipids were detected, and the assessment of insulin resistance was conducted through the homeostasis model assessment of insulin resistance (HOMA-IR). Results Among the 355 obese T2DM patients, there were 280 cases of insulin resistance, with the incidence rate of 78.87%. The BMI, IL-6, chemerin, TC/HDL-C, LDL-C/HDL-C, and TG/HDL-C in the insulin resistance group were higher than those in the non-insulin resistance group (P<0.05). The above insulin resistant patients were divided into 4 subgroups by means of insulin resistance, and there were significant differences in BMI, IL-6, chemerin, and TG/HDL-C among the subgroups (P<0.05). IL-6, chemerin, and TG/HDL-C were positively correlated with HOMA-IR in obese T2DM patients (P<0.05), while TC/HDL-C and LDL-C/HDL-C had no significant correlation with HOMA-IR (P>0.05). BMI, IL-6, chemerin, and TG/HDL-C were all influencing factors of insulin resistance in obese T2DM patients (P<0.05). Conclusion IL-6, chemerin and TG/HDL-C are correlated with insulin resistance in obese patients with T2DM and are influencing factors for the occurrence of insulin resistance.

【Objective】 To compare the outcomes of robot-assisted laparoscopic transperitoneal and retroperitoneal operation for huge (>6 cm) adrenal tumors. 【Methods】 The clinical data of 45 patients with huge adrenal tumors who underwent robotic surgery during Jan.2017 and Dec.2021 were retrospectively analyzed, including 28 cases via the transperitoneal approach and 17 cases via the retroperitoneal approach. 【Results】 No patients were converted to open operations. There were no significant differences in postoperative drainage time (2.24±0.44 vs. 2.36±0.49) d, operation time (130.88±5.96 vs. 136.61±8.39) min, blood loss (189.41±13.91 vs. 192.5±12.36) mL and postoperative hospital stay (7.06±0.56 vs. 7.46±0.69) d between the retroperitoneal and transperitoneal approaches. Retroperitoneal approach was better than transperitoneal approach in early postoperative feeding [(38.82±6.75 vs. 74.14±6.57) h, P<0.01] . 【Conclusion】 Robotic surgery is safe and effective in the treatment of large adrenal tumors. The choice of surgical approach should be based on patients’ condition, tumor volume and location.

OBJECTIVE To study the moderation effect of water extract of Farfarae Flos on blood lipid and glucose regulation in obese mice. METHODS Chemical method was used to identify the components of the water extract of Farfarae Flos. The contents of total terpenes in the water extract of the Farfarae Flos were determined by UV-VIS spectrophotometry. The mice were randomly divided into blank group, model group, orlistat group, and low-dose, medium-dose, and high-dose groups of water extract of Farfarae Flos. The blank group was fed with ordinary diet, while the other groups were fed with high-fat and high-sugar diet to establish an obese animal model, and they were administration while molding for 45 d. At the end of the experiment, the contents of serum triglyceride(TG), cholesterol(CHO), high-density lipoprotein-C(HDL-C), low-density lipoprotein-C(LDL-C), glucose(GLU), and glycosylated serum protein(GSP) were detected. Hematoxylin-eosin(HE) and oil red O staining were used to observe the morphological changes and lipid droplet distribution of liver tissue in mice. RESULTS There were flavonoids and terpenoids in the water extract of the flower. Compared with the blank group, the levels of TG, CHO, LDL-C, GLU and GSP in the model group were significantly increased(P<0.05 or P<0.01), HDL-C was significantly decreased(P<0.05), and the area of lipid droplets in the liver was significantly increased(P<0.01). Compared with the model group, TG, LDL-C, CHO, GLU and GSP levels in the Farfarae Flos water extract groups were significantly decreased, HDL-C was increased, and lipid droplet accumulation were reduced. Compared with the model group, the blood lipid and blood glucose levels in the treatment groups were significantly decreased, among them, the high-dose group of the water extract of Farfarae Flos had the best effect. CONCLUSION The water extract of farfara can improve glucose and lipid metabolism in obese mice by reducing blood lipids, CHO, and improving the pathological morphology of liver tissue.

Although NPM1 mutations are frequently found in acute myeloid leukemia patients, therapeutic strategies are scarce and unsuitable for those who cannot tolerate intensive chemotherapy. Here we demonstrated that heliangin, a natural sesquiterpene lactone, exerts favorable therapeutic responses in NPM1 mutant acute myeloid leukemia cells, with no apparent toxicity to normal hematogenous cells, by inhibiting their proliferation, inducing apoptosis, causing cell cycle arrest, and promoting differentiation. In-depth studies on its mode of action using quantitative thiol reactivity platform screening and subsequent molecular biology validation showed that the ribosomal protein S2 (RPS2) is the main target of heliangin in treating NPM1 mutant AML. Upon covalent binding to the C222 site of RPS2, the electrophilic moieties of heliangin disrupt pre-rRNA metabolic processes, leading to nucleolar stress, which in turn regulates the ribosomal proteins-MDM2-p53 pathway and stabilizes p53. Clinical data shows that the pre-rRNA metabolic pathway is dysregulated in acute myeloid leukemia patients with the NPM1 mutation, leading to a poor prognosis. We found that RPS2 plays a critical role in regulating this pathway and may be a novel treatment target. Our findings suggest a novel treatment strategy and lead compound for acute myeloid leukemia patients, especially those with NPM1 mutations.
