OBJECTIVETo investigate the pathological diagnostic features and the differential diagnosis of radial sclerosing lesions of the breast.
METHODSMorphological observation and immunohistochemistry were applied to forty-four cases of radial sclerosing lesions of the breast.
RESULTSAll forty-four patients were females, the mean age was 40.3 years (range 17 to 54 years). In the 31 consultation cases, 13 were misdiagnosed as carcinoma. The lesions had a radiating outline, and a central scar area where squeezed or pressed irregular shaped tubules were frequently seen. Dilated tubules and proliferated ducts or lobules were seen radically arranged at the periphery accompanied sometimes with the apocrine glands or columnar cell metaplasia and hyperplasia. Aside, there were 14 cases displaying necroses and 8 cases showing atypical ductal hyperplasia. Immunostaining showed myoepithelial cells around the pseudo-infiltrating tubules, and the florid proliferating epithelial cells were positive for CK5/6.
CONCLUSIONSRadial sclerosing lesions of the breast possess characteristic histological features, and may be misdiagnosed as carcinoma. The lesions should be differentiated from ductal carcinoma in situ, lobular neoplasia, tubular carcinoma and invasive ductal carcinoma.

Tumorous cells are characterized by distinctive metabolic reprogramming and living conditions. Understanding drug metabolizing features in tumor cells will not only favor the estimation of metabolic rate, elimination half life and the assessment of potency, but also facilitate the optimal design of anti-tumor drugs/prodrugs. This article reviewed the expression and activity features of major drug metabolizing enzymes (DMEs) in solid tumorous tissues, such as liver, intestine, breast and lung, and the difference from the correspondingly normal tissues, exemplified by the metabolic properties of some classic antitumor-agents in tumorous tissues. In combination with the data retrieved in vitro tumor cell lines, we discussed the similarities and differences of DMEs expression and function between tumor tissues (in vivo) and tumor cells (in vitro), and proposed the possible factors that cause the differences.

UNLABELLEDOBJECTIVE To observe the clinical efficacy by Qingying Huoxue Decoction (QHD) combined ursodeoxycholic acid (UDCA) in treating patients with early and mid-term primary biliary cirrhosis (PBC). METHODS Totally 78 patients were randomly assigned to the treatment group and the control group, 39 in each group. All patients received basic treatment and took UDCA (at the daily dose of 13-15 mg/kg). Patients in the treatment group took QHD, one dose per day. The treatment course for all was 6 weeks. Clinical efficacy, gamma-glutamyl transferase (γ-GGT), alkaline phospatase (ALP), TBIL, alanine aminotransferase (ALT), and aspartate transaminase (AST) were observed before and after treatment. RESULTS Totally 21 (53. 8%) patients obtained complete response in the treatment group, with statistical difference when compared with that of the control group (11 cases, 30. 8%). Levels of GGT, ALP, ALT, AST, and TBIL decreased in the two groups after treatment (P < 0.01). Levels of ALP, GGT, and TBIL were obviously lower in the treatment group than in the control group (P < 0.05).
CONCLUSIONSQHD combined UDCA in treating early and mid-term PBC patients was superior to the effect of using UDCA alone. It also could improve patients' liver function.

We revisited the "Xiao Chaihu Decoction event (XCHDE)" occurred in late 1980s in Japan and the Bupleuri Radix related adverse drug reaction (ADR) reports in China After careful review, comparison, analysis and evaluation, we think the interstitial pneumonitis, drug induced Liver injury (DILI) and other severe adverse drug envents (ADEs) including death happened in Japan is probably results from multiple factors, including combinatory use of XCHDE with interferon, Kampo usage under modern medicine theory guidance, and use of XCHD on the basis of disease diagnosis instead of traditional Chinese syndrome complex differentiation. There are less ADE case reports related to XCHD preparation in China compared to Japan, mostly manifest with hypersensitivity responses of skin and perfuse perspiration. The symptoms of Radix Bupleuri injection related ADEs mainly manifest hypersensitivity-like response, 2 cases of intravenous infusion instead of intramuscular injection developed hypokalemia and renal failure. One case died from severe hypersensitivity shock. In Chinese literatures, there is no report of the interstitial pneumonitis and DILI associated with XCHDG in Japan. So far, there is no voluntary monitoring data and large sample clinical research data available. The author elaborated the classification of "reevaluation" and clarified "re-evaluation upon events" included the reaction to the suspected safety and efficacy events. Based on the current status of the clinical research on the Radix Bupleuri preparations, the author points out that post-marketing "re-evaluation upon suspected event" is not only a necessity of continuous evaluation of the safety, efficacy of drugs, it is also a necessity for providing objective clinical research data to share with the international and domestic drug administrations in the risk-benefit evaluation. It is also the unavoidable pathway to culture and push the excellent species and famous brands of TCM to the international market, in that it enhances the pharmaceutical manufactures the ability to control enterprise risk and eliminate the negative impact on traditional Chinese medicine. With the widely used and ADR report concentrated Radix Bupleuri injection as an example, the author provide a new approach to post-marketing clinical research.

OBJECTIVETo explore the effect of Telbivudine (LDT) Tablet combined with Jianpi Bushen Recipe (JBR) on serum hepatitis B virus (HBV) specific cytotoxic T lymphocyte (CTL) and HBeAg seroconversion in chronic hepatitis B (CHB) patients.
METHODSTotally 90 HBeAg-positive and human leukocyte antigen (HLA)-A2 positive CHB patients were randomly assigned to the treatment group and the control group, 45 cases in each group. Patients in the treatment group took LDT Tablet (600 mg, once per day) combined with JBR granule (twice per day), while those in the control group took LDT Tablet alone. The therapeutic course for all was one year. HBV DNA negative conversion rate, HBeAg seroconversion rate, and level of HBV specific CTL were compared after 1 year treatment; liver function, drug resistance mutations, and adverse reactions were also compared between the two groups.
RESULTSAfter 1 year treatment, HBV DNA negative conversion rate and HBeAg seroconversion rate were 88.89% (40/45) and 40.00% (18/45) in the treatment group, higher than those of the control group [68.89% (31/45) and 20.00% (9/45)], with statistical difference (P < 0.05). Level of HBV specific CTL in the treatment group was 0.78% +/- 0.09% after treatment, higher than that of the control group after 1 year treatment (0.54% +/- 0.11%) and that before treatment (0.36% +/- 0.07%), with statistical difference (P < 0.01). Level of HBV specific CTL in 27 patients with HBeAg seroconversion was 0.81% 0.10%, higher than that of 63 patients without HBeAg seroconversion (0.60% +/- 0.09%), with statistical difference (P < 0.01). ALT returned to normal in 44 cases of the treatment group (97.78%), while it was 42 cases (93.33%) of the control group, with no statistical difference between the two groups (P > 0.05). Total bilirubin (TBil) in the two groups all turned to normal. rtM204I variation occurred in 1 case (2.22%) of the treatment group and 2 cases (4.44%) in the control group. No obvious adverse reaction occurred in the two groups.
CONCLUSIONLDT Tablet combined with JBR could elevate levels of HBV specific CTL and HBeAg seroconversion in CHB patients.

OBJECTIVETo investigate the relationship between the genetic polymorphisms of CYP3A5 and the clinical effectiveness of Bicyclol on patients with chronic hepatitis B to make individual medication possible.
METHODS34 cases of chronic hepatitis B were treated by bicyclol tablets for 24 weeks. Liver function indexes (ALT and AST) were determined before and after treatment. Blood CYP3A5 genotyping of each patient was determined by the PCR-RFLP analysis.
RESULTSAll subjects were genotyped for the CYP3A5*3 gene and divided into different group. The groups comprised subjects with CYP3A5*3 carriers (n=18) and CYP3A5*1 carriers (n=16) which include CYP3A5*1/*1 (n=2) and CYP3A5*1/*3 (n=14). Compared with pre-treatment, the serum ALT and AST levels were decreased obviously in all patients. The mean percentage reduction of serum ALT and AST levels were significantly greater in subjects with CYP3A5*3 carriers (79.73% and 74.76%) than in those with CYP3A5*1 carriers (65.90% and 49.63%; P < 0.05) The recovery rates of ALT and AST were significantly highter in CYP3A5*3 carriers than those in CYP3A5*1 carriers (P < 0.05).
CONCLUSIONCYP3A5 genotype has an impact on the therapeutic effects of Bicyclol. The subjects with CYP3A5*3 carriers is more effective than the subjects with CYP3A5*1 carriers. CYP3A5 genotyping may be helpful in predicting therapeutic effects of Bicyclol especially in the terms of decreasing ALT and AST.
