Clinical observation of Ruyi jinhuang powder combined with ICIs in the treatment of advanced liver cancer complicated with dampness and heat syndrome of liver and gallbladder / 中国药房

OBJECTIVE To explore the clinical efficacy and safety of Ruyi jinhuang powder for external application combined with immune checkpoint inhibitors （ICIs） in the treatment of patients with advanced liver cancer complicated with dampness and heat syndrome of liver and gallbladder. METHODS All patients with advanced liver cancer complicated with dampness and heat syndrome of liver and gallbladder were admitted to our hospital from January 2018 to June 2022 and assigned into observation group and control group according to random number table method. Patients in the control group （n＝56） were treated with ICIs （Navulizumab injection/Sintilimab injection/Camrelizumab for injection） 200 mg， ivgtt， 21 days as a treatment cycle. Patients in the observation group （n＝56） were additionally treated with Ruyi jinhuang powder for external application， once a day， on the basis of control group. The therapeutic effects of 2 groups were compared after a treatment cycle. The levels of interleukin-6 （IL- 6）， matrix metalloproteinase-9 （MMP-9）， cyclooxygenase-2 （COX-2）， prostaglandin E2 （PGE2）， carbohydrate antigen 199 （CA199）， alpha-fetoprotein （AFP） and vascular endothelial growth factor （VEGF） in serum were compared between 2 groups before and after treatment. Karnofsky functional status （KPS） score， digital rating scale （NRS） score， total symptom score of traditional Chinese medicine， and the occurrence of adverse reactions were recorded for both groups of patients. RESULTS After treatment， the levels of IL-6， MMP-9， COX-2， PGE2， CA199， AFP， VEGF， NRS score and total symptom score of traditional Chinese medicine in observation group were significantly lower than control group （P＜0.05）， KPS score was significantly higher than the control group （P＜0.05）. The zypp-04） total effective rate and remission rate of the observation group were 64.29% and 80.36%， those of control group were 60.71% and 73.21%. There was no statistical significance between two groups （P＞0.05）. The adverse drug reactions of both groups were mainly nausea and vomiting， liver function injury， fever hlshli@yeah.net and so on； the incidence of adverse reaction in observation group was significantly lower than that of control group （P＜0.05）. CONCLUSIONS In patients with advanced liver cancer complicated with dampness and heat syndrome of liver and gallbladder， the combination of Ruyi jinhuang powder for external application and ICIs can help inhibit the secretion of pain mediators， regulate vascular endothelial function， reduce the inflammatory response， promote the recovery of cardiopulmonary function， improve clinical efficacy and has good safety.

Simultaneous Determination of 5 Components in Chanlong Dingchuan Mixture by HPLC / 中国药房

OBJECTIVE:To establish a method for the simultaneous determination of psoralen,isopsoralen,epimedin B,epi-medin C and icariin in Chanlong dingchuan mixture. METHODS:HPLC was performed on the column of Welch Materials C18 with mobile phase of acetonitrile- methanol(1∶1,V/V)-water(gradient elution)at a flow rate of 0.9 ml/min,the detection wavelength was 246 nm(psoralen,isopsoralen)and 270 nm(epimedin B,epimedin C and icariin),column temperature was 30 ℃,injection volume was 20 μl. RESULTS:The linear range was 8.24-164.80 μg/ml for psoralen(r=0.999 7),5.15-103.00 μg/ml for isopso-ralen(r=0.999 3),4.06-81.20 μg/ml for epimedin B(r=0.999 6),5.88-117.60 μg/ml for epimedin C(r=0.999 5)and 4.90-98.00μg/ml for icariin(r=0.999 8);the limits of quantitation were 0.385 μg/ml,0.179 μg/ml ,0.124 μg/ml,0.218 μg/ml and 0.348 μg/ml, limits of detection were 0.127μg/ml,0.059μg/ml ,0.041μg/ml,0.072μg/ml and 0.115μg/ml;RSDs of precision,stability and re-producibility tests were lower than 2.0%;recoveries were 97.93%-100.06%(RSD=0.80%,n=6),96.91%-100.16%(RSD=1.37%,n=6),96.95%-99.63%(RSD=0.98%,n=6),96.69%-99.33%(RSD=1.03%,n=6) and 96.76%-98.53%(RSD=0.70%,n=6),respectively. CONCLUSIONS:The method is simple and reliable,and suitable for the simultaneous determination of psoralen,isopsoralen,epimedin B,epimedin C and icariin in Chanlong dingchuan mixture.

One case report on orbital and hepatic metastases from primary pancreatic carcinoma / 实用肿瘤学杂志

Orbital metastases rarely occur in the patients with cancer,especially from a primary pancreat-ic carcinoma.In patients presenting ophthalmologic symptoms such as local pain and periorbital edema,it is im-portant to consider orbital metastatic disease.And it is also crucial to determine the site of the primary tumor for better treatments.The mechanism underlying the orbital metastasis from pancreatic carcinoma remains to be clari-fied.In this report,we describe the clinical characteristics of a case with orbital and hepatic metastases from pri-mary pancreatic carcinoma,providing a reference for clinical diagnosis.Computed tomography of the abdomen and left orbit,in combination with intraorbital biopsy,suggesting a primary pancreatic malignancy with metastatic dis-ease.Surgical pathology and histopathological examination results confirmed the diagnosis.After single agent gem-citabine chemotherapy,the patient′s symptoms relieved.

Tamoxifen and fatty fiver disease / 国际肿瘤学杂志

Tamoxifen has shown definitive effect when used as the adjuvant hormonal treatment in women with estrogen-receptor-positive breast cancer. However, long-term use of Tamoxifen can induce fatty liver disease. It has been proposed that tamoxifen may act throught mechanisms such as inducing triacylglycerol accumulation in mitochondria, abnormal fatty acid oxidation, and antagonizing actions of estrogen on hepatic lipid metabolism. Therefore, it is necessary to monitor lipid profile and liver function, conduct regular ultrasonography and CT examination in patients receiving tamoxifen treatment. Replacing tamoxifen with toremifene oraromatase inhibitors, or using lipid-lowering medicines may help prevent tamoxifen-induced fatty liver disease.
