Objective: To investigate the effects of recombinant human growth hormone (rhGH) and 5-fluorouracil(5-Fu) on human colon carcinoma LOVO cells in vitro. Methods: The LOVO cells during exponential growth stage were harvested and divided into control group,GH group, 5-Fu group and GH + 5-Fu group. According to the dose of GH, the GH group was separated into two sub-groups(50 ng/mL and 100 ng/mL) and the GH +5-Fu group was separated into two sub-groups. With different concentrations of rhGH and/or 5-Fu , the cell survive rates were analyzed by MTT assay after 24 h , 48 h and 72 h and cell cycle and proliferation index (PI) were analyzed by flow cytometry after 24 h. Results: Compared with the control group, the survive rates in 5-Fu and GH +5-Fu groups were decreased significantly (P <0. 05). The significant effects of rhGH on cell cycle kinetics were found in the cell line. Compared with the control group, percentage of S phase and proliferation index (PI) significantly increased (P <0.05)and percentage of G_0/G_1 phase decreased (P <0. 05) in GH groups. Percentages of cells of S phase and PI significantly decreased in GH + 5-Fu groups (P < 0. 05). Rate of apoptosis increased in 5-Fu and GH +5-Fu groups (P <0.05). Compared with the 5-Fu group, there were no statistically significant differences in percentages of cells of S phase and PI and rate of apoptosis between two GH+5-Fu groups(P >0. 05). Conclusion-. rhGH does not stimulate the LOVO cells proliferation in vitro, and its use is safe when combined with 5-fluorouracil.

Objective:To retrospectively analyze the incidence, mortality, clinical characteristics and related factors of transient and persistent acute kidney injury in patients with sepsis in emergency department.Methods:Patients with sepsis ≥ 18 years old hospitalized in the Emergency Department of Guangdong Provincial Hospital of Chinese Medicine from June 2018 to May 2020 were selected as the research objects. According to the renal function injury at admission and the renal function recovery at 48 h after admission, patients with sepsis were divided into three groups: non-S-AKI group, transient S-AKI group, and persistent S-AKI group.Results:A total of 197 patients with sepsis were included, including 95 patients with non-S-AKI, 39 patients with transient S-AKI and 63 patients with persistent S-AKI. The mortality in the persistent S-AKI group was significantly higher than that in the non-S-AKI group (36.5% vs. 17.9%, P<0.05), but there was no significant difference between the transient S-AKI group and non-S-AKI group (20.5% vs. 17.9%, P>0.05). Multiple categorical disordered Logistic regression analysis showed that urea was associated with transient S-AKI ( OR=1.440, 95% CI: 1.235-1.680), and age ( OR=1.049, 95% CI: 1.008-1.092), urea ( OR=1.440, 95% CI: 1.277-1.733), and infection site in non-urinary tract ( OR=0.149, 95% CI: 0.050-0.448) were associated with persistent S-AKI. Conclusions:The incidence of persistent S-AKI is higher than that of transient S-AKI. Persistent S-AKI is related to the prognosis of patients with sepsis, and the mortality rate is higher, while transient S-AKI has no significant relationship. The urea of patients with S-AKI would increase significantly, and advanced age and urinary tract infection are related factors for the occurrence of persistent S-AKI. For patients with sepsis with such factors, attention should be paid to early protection of renal function to prevent persistent S-AKI.

Objective:To analyze the impact of gender on prognosis in patients with primary hepatocellular carcinoma (HCC) after hepatectomy.Methods:The data of 1 796 patients with HCC who underwent liver resection at the Guangxi Medical University Cancer Hospital from January 2010 to December 2016 were retrospectively analyzed. There were 1 548 males and 248 females, the average age were 49.6 years. Patients were followed up for recurrence and survival. After propensity score matching, the postoperative survival rates of male and female patients were compared. Univariate and multivariate Cox regression was used to analyze independent factors affecting prognosis of patients with HCC after hepatectomy. The age and menopause were analyzed by subgroup analyses.Results:The 1-, 3- and 5-years cumulative overall and recurrence-free survival rates of male patients were significantly lower than that of female patients (all P<0.05). Multivariate analysis showed that female was an independent protective factor affecting postoperative recurrence ( HR=0.777, 95% CI: 0.615-0.982) and overall survival ( HR=0.669, 95% CI: 0.520-0.856). Using a cut-off value of 50 years old, the patients were divided into <50 years old ( n=915) and ≥50 years old ( n=881). In patients who were less than 50 years old, the 1-, 3- and 5-years cumulative overall and recurrence-free survival rates of male patients were significantly lower than those of female patients (all P<0.05). In patients ≥50 years old, there were no significant difference in the cumulative overall and recurrence-free survival rates between male and female patients (all P>0.05). Female patients were then divided into the postmenopausal group ( n=152) and the premenopausal group ( n=96). There were no significant differences in the cumulative overall and cumulative recurrence-free survival rates between the two groups ( P>0.05). Conclusion:The prognosis of female patients with HCC after hepatectomy was significantly better than that of male patients.
