AIM: To observe the effect ofacacia honey (AH) on serum uric acid level and renal function in potassium oxonate modelrats after drinking AH aqueous solution. METHODS: Sixty male SD rats were selected and randomly divided into control group (CON group), potassium oxonate model group (OA model group), 10% fructose group (10% F group) and different concentration honey groups (25%, 12.5% and 6.25% AH groups). All rats were fed with normal diet.The rats in CON group were subcutaneously injected with 5% sodium carboxymethyl cellulose (CMC-Na) solution and drunk sterile water every day, while rats in other groups were injected with 100 mg / kg OA solution suspended with 5% CMC-Na subcutaneouslyand drunksterile water orfructose solution or AH solution of different concentrations every day. Before and during the 4-week test, rats were weighed and blood was taken once a week. At the end of test, urine and feces specimens or kidney tissues were collected and blood was taken from the abdominal aorta. The uric acid content in blood, urine, and feces and the levels of serum creatinine (Cre) and blood urea nitrogen (BUN) or inflammatory factors in kidney tissues were measured. Renal function and histology were evaluated. RESULTS: Compared with CON group, AH could significantly reduce the body weight of rats (P<0.05), increase the kidney organ coefficient, the levels of serum uric acid, and uric acid in urine or feces, and reduce the level of fecal uric acid (FUA) in rats. AH can down regulate the level of tumor necrosis factor alpha (TNF-a) (P< 0.05) and up regulate the expression of monocyte chemoattractant protein 1 (MCP-1) and transforming growth factor β - 1 (TGF - β1) in rats kidneys; AH can cause slight to mild dilatation of renal tubules and mild to moderate basophilic lesions of renal rubules in rat kidney in a dose dependent manner. CONCLUSION: In the doses rang of present study, AH can cause hyperuricemia, renal tubular dilatation and basophilic lesions, and lead to renal function damage in rats.
RESUMEN
Hepatocellular carcinoma (HCC) is one of the most common malignant tumors in clinical practice and has the features of high incidence rate, poor prognosis, and high mortality rate, and its incidence rate and mortality rate rank among the top malignant tumors in the world. High heterogeneity of HCC affects the evolution and therapeutic response of HCC. Since most HCC patients are in the advanced stage at the time of diagnosis, systemic treatment has become the main treatment option. In recent years, remarkable achievements have been made in molecular targeted therapy and immunotherapy for HCC, and the latest NCCN guidelines for the systemic treatment of HCC show that sorafenib, lenvatinib, and atezolizumab combined with bevacizumab are recommended as the first-line treatment of HCC, and regorafenib, cabozantinib, nivolumab, pembrolizumab, and ramucirumab are the second-line treatment options for HCC. In the era of precision medicine, how to select the optimal individualized systemic treatment regimen is the key problem in the systemic treatment of HCC. This article reviews the advances in the systemic treatment of HCC in the era of precision medicine and discusses the development direction of HCC treatment in the future.
RESUMEN
Objective@#To investigates the role of piwi-interacting RNAs (piRNA) in the occurrence and development of hepatocellular carcinoma.@*Methods@#Second-generation small RNA sequencing was performed on cancer and paracancerous tissues, metastatic and non-metastatic liver cancer tissues of patients with liver cancer, and the sequencing data were filtered out for the common RNA sequences to be repeated. The piRNA predictor was used to forecast the possible new piRNA merged with the downloaded known piRNA to screen out distinction. A miRanda algorithm was used to predict the corresponding target genes and functional enrichment analysis. piRNA was selected for experimental functional (migration) analysis. An independent t-test was used to compare means between the two groups.@*Results@#66 772 piRNAs (known 149) were obtained by sequencing. 241 piRNAs were found in cancer and paracancerous tissues, and 1 634 piRNAs were found in metastatic and non-metastatic tumors. Analysis of the GO and KEGG pathways of the target genes of differential piRNAs revealed that they were mainly involved in cell adhesion. An experimental functional analysis was performed on the selected Pirna (PIR1/97), which showed that it promoted the migration of hepatoma cells (LM3: t = 8.829, P < 0.05; PLC: t = 7.318, P < 0.05).@*Conclusion@#The expression levels of piRNA in hepatocellular carcinoma patients with cancer and paracancerous tissues, metastasis and non-metastatic liver cancer tissues are different and it could be entailed in the metastasis process of hepatocellular carcinoma. Hence, experimental functional analysis is required for research and experimental confirmation.

Objective To observe clinical effects of Guilong decoction combined conventional western medi-cine in the treatment of rheumatoid arthritis with cold-dampness syndrome.Methods 106 cases of rheumatoid arthri-tis with cold-dampness syndrome were randomly divided into the treatment group and the control group,with 53 cases in each group.The control group was orally given methotrexate and hydroxychloroquine,while the treatment group was given Guilong decoction based on the treatment of the control group.The clinical effects of the two groups were observed after a treatment course of 3 months.Results In the treatment group,35 cases were markedly effective, which was significantly higher than the control group(P 0.05).The total effective rate of the treatment group was 88.68%, which was significantly higher than the control group (χ2 =4.810,P =0.028).There were no significant differences of the adverse reaction ratio between the two groups(P >0.05).Conclusion Guilong decoction combined with con-ventional western medicine can obviously improve the rheumatoid arthritis disease severities,the curative effect is re-markable.It is worth popularizing in clinical application.
