OBJECTIVETo study the effects of Jinhuang Yidan Granule (JYD) on the bile compositions of primary bile duct pigment calculus patients.

METHODSSixty-six patients with primary bile duct pigment calculus were randomly assigned to the control group (who took no Chinese medicine) and the JYD group (who took JYD). The bile from T-tube during the operation, 3, 10, and 40 days after medication were examined. The contents of bile acids, bilirubin (conjugated bilirubin, mono-conjugated bilirubin), glucoprotein, calcium ion, beta-glucuronidase, superoxide radical anion, and other components were detected and compared.

RESULTSThree days after taking JYD, the total bile acids increased, the total bilirubin and beta-glucuronidase decreased, showing statistical significance when compared with the control group (P < 0.05). In the JYD group, the total bile acid increased, the total bilirubin, the conjugated bilirubin, the mono-conjugated bilirubin, glucoprotein, calcium ion, beta-glucuronidase, superoxide radical anions decreased 10 and 40 days after medication, showing statistical significance when compared with the control group (P < 0.05, P < 0.01). The level of the total bile acid increased, the levels of the total bilirubin, the conjugated bilirubin, the mono-conjugated bilirubin, glucoprotein, calcium ion, beta-glucuronidase, superoxide radical anions decreased after 40-day medication in the two groups, showing statistical significance when compared with the peri-operative indices of the same group (P < 0 05, P < 0.01).

CONCLUSIONSJYD could significantly improve the pathologic bile compositions of the bile duct calculus, improve the environment of the biliary tract, showing certain preventive and therapeutic effects on bile pigment calculus of the primary bile duct calculus. Better effects may be obtained by long-term taking.

Purpose To investigate the value of application of D2-40/CD34-CK cocktail antibodies by double immunohistochemical staining for assessment of lymphovascular invasion (LVI) and to determine its prognostic significance in colorectal cancer with insufficient lymph node harvest. Methods Specimens from 133 cases of colorectal cancer with less than 12 lymph nodes were selected. HE staining and double immunohistochemical staining of the cocktail antibodies were performed to compare the difference of the two methods in screening for LVI. The The relationship between LVI confirmed by cocktail antibody immunohistochemical staining and clinicopathological characteristics and overall survival (OS) of patients was analyzed. Results (1) The detection rates of cocktail antibody double immunohistochemical staining and HE staining for LVI were 42.9％ (57/133) and 21.8％ (29/133) with statistically significant difference (P < 0.001). (2) The presence of LVI confirmed by double staining was significantly associated with Dukes staging, depth of invasion, clinical stages, lymph node metastasis and tumor budding (P < 0.05). (3) The presence of LVI, the location and extent of LVI, and the number of tumor cells in thrombus ≥5.5 for cases with LVI ≤2 clusters, were significantly associated with OS (P < 0.05). Conclusion D2-40/CD34-CK cocktail antibodies double staining is superior to routine HE staining in assessing LVI. LVI is intimately associated with tumor stage, lymph nodes metastasis and tumor budding, and it is an independent prognostic factor for CRC patients. It should be a supplementary examination for these patients with insufficient lymph node harvest.
