Efficacy of erzhu jiedu recipe on hepatitis B cirrhosis with hyperalphafetoproteinemia: A randomized, double-blind, placebo-controlled clinical trial.

BACKGROUND: Hepatitis B cirrhosis with hyperalphafetoproteinemia is the intermediate stage of liver cirrhosis progressing to hepatocellular carcinoma (HCC), there is no effective way to treat precancerous lesions of liver in modern medicine. In recent decades, clinical and experimental evidence shows that Chinese medicine (CM) has a certain beneficial effect on Hepatitis B Cirrhosis. Therefore, this trial aims to evaluate the efficacy and safety of a CM erzhu jiedu recipe (EZJDR) for the treatment of Hepatitis B Cirrhosis with Hyperalphafetoproteinemia. METHODS: We designed a randomized, double blind, placebo-controlled clinical trial. A total of 72 patients of Hepatitis B Cirrhosis with hyperalphafetoproteinemia were randomized in 2 parallel groups. Patients in the control group received placebo granules similar to the EZJDR. In the EZJDR group, patients received EZJDR twice a day, after meals, for 48 weeks. The primary efficacy measures were changes in serum alpha-fetoprotein (AFP) and alpha-fetoprotein alloplasm (AFP-L3); The secondary indicators of efficacy are changes in liver function indicators, HBV-DNA level; Liver stiffness measurement (LSM); Hepatic portal vein diameter; T lymphocyte subgroup indexes during treatment. All data will be recorded in case report forms and analyzed by Statistical Analysis System software. Adverse events will also be evaluated. RESULTS: The results showed that EZJDR can significantly inhibit the levels of AFP and AFP-L3 in patients with hepatitis B cirrhosis and hyperalphafetoproteinemia and have good security. ETHICS AND DISSEMINATION: The study protocol was approved by the Medical Ethics Committee of Shuguang Hospital, affiliated with University of Traditional Chinese Medicine, Shanghai (NO.2018-579-08-01). TRIAL REGISTRATION: This trial was registered on Chinese Clinical Trial Center (NO.ChiCTR1800017165).

Mechanism of Modified Liuwei Dihuangtang in Bone Protection of CKD-MBD Model Rats： An Exploration Based on Klotho-FGF23 Axis / 中国实验方剂学杂志

Objective:To observe the effects of modified Liuwei Dihuangtang on serum fibroblast growth factor 23 （FGF23）， full-length intact parathyroid hormone （iPTH）， and 1，25-dihydroxyvitamin D₃［1，25（OH）₂D₃］ levels and Klotho and FGF23 protein expression in renal and bone tissues of rats exposed to high phosphorus combined with adenine， so as to explore the mechanism of modified Liuwei Dihuangtang against renal osteopathy. Method:One hundred and thirty healthy adult SD rats were randomly divided into five groups， namely normal group（<italic>n</italic>=10），high phosphorus group（<italic>n</italic>=30），model group（<italic>n</italic>=30），modified Liuwei Dihuangtang group（<italic>n</italic>=30） ， and calcitriol group（<italic>n</italic>=30），and rats in each group were further classified based on three time points， namely 8，10， and 12 weeks. Rats in the normal group were fed with normal diet， the ones in the high phosphorus group with high phosphorus diet， and those in the other groups with adenine and high phosphorus diet for inducing renal osteopathy. Rats in the normal group，high phosphorus group， and model group were intragastrically administered with distilled water （10 mL·kg^-1·d^-1），the ones in the modified Liuwei Dihuangtang group with modified Liuwei Dihuangtang （2.556 g·kg^-1·d^-1） ， and those in the calcitriol group with calcitriol （0.09 μg·kg^-1·d^-1）. Result:Compared with the normal group and high phosphorus group at the weeks of 8，10 and 12，the model group displayed significantly elevated blood urea nitrogen（BUN），serum creatinine（SCr），serum phosphorus，iPTH，FGF23，renal interstitial fibrosis score， and FGF23 expression in renal and bone tissues， but lowered serum calcium and 1，25（OH）₂D₃ and Klotho protein expression in renal and bone tissues（<italic>P</italic><0.05 ，<italic>P</italic><0.01）. Compared with the model group at the weeks of 8，10 and 12， the modified Liuwei Dihuangtang and calcitriol both significantly decreased the serum BUN，SCr，serum phosphorus，iPTH， FGF23， tubulointerstitial semi-quantitative score， and FGF23 expression in renal and bone tissues， while increased the serum calcium，1，25（OH）₂D₃， and Klotho protein expression in renal and bone tissues （<italic>P</italic><0.05，<italic>P</italic><0.01）. There was no significant difference in the above-mentioned indexes between the modified Liuwei Dihuangtang group and the calcitriol group at the same time point. Conclusion:Klotho-FGF23 axis is probably involved in renal osteopathy. The modified Liuwei Dihuangtang effectively improves renal function，alleviates pathological changes in renal and bone tissues，and regulates calcium and phosphorus metabolism to protect the bone， which is related to its regulation of Klotho-FGF23 axis.

Efficacy of capecitabine and oxaliplatin regimen for extrahepatic metastasis of hepatocellular carcinoma following local treatments.

AIM: To investigate the efficacy and safety of capecitabine and oxaliplatin (CapeOx) for extrahepatic metastasis after local treatment of hepatocellular carcinoma (HCC). METHODS: Thirty-two patients with extrahepatic metastasis of HCC after local treatment were prospectively enrolled. The CapeOx regimen consisted of capecitabine 1000 mg/m(2) taken orally twice daily on days 1-14, and oxaliplatin was administered at a total dose of 100 mg/m(2) on day 1. The treatment was repeated every 3 wk until disease progression or unaccetablle toxicity. Efficacy and safety were assessable for all enrolled patients. The primary objective of this study was to assess the overall response rate. The secondary objectives were to evaluate the overall survival (OS), the time to tumor progression (TTP) and the toxicity profile of the combined strategy. TTP and OS were assessed by the Kaplan-Meier method and differences between the curves were analyzed using the log-rank test. The statistical software SPSS version 15.0 for Windows (SPSS Inc., Chicago, IL, United States) was used for statistical analysis. All P values were 2-tailed, with statistical significance defined by P ≤ 0.05. RESULTS: Thirty-two patients were assessable for efficacy and toxicity. The median follow-up duration was 15 mo (range, 12-20 mo). At the cut-off date of March 31, 2012, 27 patients died due to tumor progression and one patient died of myocardial infarction. Four patients were still alive (three patients with disease progression). OR was 21.9% (n = 7), the stabilization rate was 40.6% (n = 13), and the disease control rate was 62.5%. The responses lasted from 4 to 19 mo (median, 6 mo). Median TTP was 4.2 mo (95%CI: 2.5-7.4), and the median OS time was 9.2 mo (95%CI: 6.5-17.8). The 1-year survival rate was 43.6% (95%CI: 29.0-66.0). In a multivariate analysis, OS was significantly longer in patients with a Child-Pugh class A compared with class B patients (P = 0.014), with a median OS of 10.1 mo vs 5.4 mo, and there were trends towards longer OS (P = 0.065) in patients without portal vein tumor thrombosis. There were no significant effects of age, gender, performance status, cirrhosis, metastatic sites, and level of alpha fetoprotein (AFP) or hepatitis B virus-DNA on OS. Among the 22 patients with elevated AFP levels at baseline (≥ 400 ng/mL), the level fell by more than 50% during treatment in 6 patients (27.3%). The most frequent treatment-related grade 3 to 4 toxicities included leucopenia/neutropenia, transient elevation of aminotransferases, hand-foot syndrome and fatigue. CONCLUSION: CapeOx showed modest anti-tumor activity in metastatic HCC. However, the manageable toxicity profile and the encouraging disease control rate deserve further study for these patients.

[Vascular endothelial cells targeted Tyr-RGD-PEG-PEI nano-drug synthesis and its biological activity].

The study is designed to synthesize nano-carrier Tyr-RGD (cyclo-[Arg-Gly-Asp-d-Tyr-Lys]) and poly(ethylene glycol) modified polyethylenimine (Tyr-RGD-PEG-PEI) targeting vascular endothelial cells, then analyze its nanoparticle properties and the characteristics of drug carrying and targeting properties in vivo / in vitro tumor. The nano-carrier Tyr-RGD-PEG-PEI was synthesized with the method of chemical synthesis and the properties of this nanoparticle and drug carrying characteristics were identified. Its effect of targeting vascular endothelial cells in vitro was studied with the method of competitive binding assay. The fluorescent labeled nano-drug was injected into tumor-bearing nude mice to observe its tumor-targeting. The mean size of nano-carrier Tyr-RGD-PEG-PE was about 145 nm, good in encapsulation efficiency of siRNA. After incubation in plasma for half an hour, only about 3 percent of siRNA out. It was confirmed that it was a single spot with TLC analysis, the R(f) value was 0.65. Receptor competition experiments showed that the nano could effectively compete with RGD in binding the receptors on endothelial cells. Tumor-bearing nude mice experiments showed that when containing a fluorescent-labeled siRNA of Tyr-RGD-PEG-PEI nano-drug was injected into mice, after 24 hours this nano-drug mainly distributed within the tumor tissue. However, nano-drug without Tyr-RGD appeared in tumor tissue as well as other organs such as livers, lungs, etc. The Tyr-RGD-targeted gene vector Tyr-RGD-PEG-PEI synthesized in this study has good nanoparticle properties and high efficiency of gene-drug encapsulation. Study of nude mice shows that the ability of its tumor-targeting is significantly better than nano-drug without Tyr-RGD.
