Traditional medicine (herb medicine) began to prevail again over last two decades, and it is about 70% of the world population taking herb medicine as supplement or alternative medicine according to a recent survey. The consumption of herb medicine increased exponentially in Canada, Australia and Europe during last 10 years. Since concomitant administration of herbal and western medicine has become a trend, it requires paying close attention to the problem. Herb-drug interactions have been extensively investigated worldwide, and there is an increasing concern about the clinical herb-drug interaction. In this review we introduced the current progress in the herb-drug interactions including evidence-based clinical studies and establishment of levels of evidence for herb-drug interaction; and in the related mechanisms including the induction and inhibition of metabolic enzymes, inhibition and induction of transport and efflux proteins, alteration of gastrointestinal functions, and alteration in renal elimination. We also analyzed both the achievements and the challenges faced in the concomitant administration of traditional Chinese medicine and western medicine.

4.Progress of studies on microenvironment of lymphoma.
Journal of Experimental Hematology 2011;19(5):1310-1313
Many studies indicate that lymphoid neoplasms are related with chromosome translocations and the molecular alterations involving in the cell cycle and/or apoptotic pathways. However, survival of B and T tumor cells also depends on interactions of these cells with the accompanying cells comprising the lymphoma microenvironment. Immune cells, stromal cells and numerous molecular together make up the microenvironment and have functional interaction with tumor cells, promoting tumor growth and drug resistance. Different types of lymphoma have various clinical courses, therapy responses and prognoses, which show a close relationship with the microenvironment. This review summarizes several components of lymphoma microenvironment including macrophages, adhesion molecules and chemokines and the roles of microenvironment in classic non-Hodgkin's lymphoma, follicular lymphoma, diffuse large B-cell lymphoma, suggesting that the microenvironment influence the prognosis of lymphoma, targeting microenvironment may be a potential method in lymphoma therapy.

Objective To evaluate the follow-up results of patients with cervical intraepithelial neoplasia Ⅲ(CIN Ⅲ)after surgical treatment.Methods A retrospective analysis of consecutive patients with CIN Ⅲ after surgical treatment between Jan 1st,1999 and Jun 30 th,2004 was performed.The follow- ups of the patients after surgical treatment were assessed.Results In the follow-up of patients with CINⅢ after surgical treatment,the rate of abnormal cytology was 9.3%.The rate of follow-up was higher in patients with cervical conization than in patients with initial hysterectomy and in patients of the oncological group than of the non-oncological group.The rate of follow-up was lower in patients over 40 years old.There was no difference in the residential areas of the patients.Conclusions Cytological follow-up of patients with CINⅢ after operation is varied.The rate of follow-up is lower in patients over 40 years old,in patients having initial hysterectomy and in patients of the non-oncological group.The rate of follow-up is associated with the knowledge about CIN of both surgeons and patients.

To determine the optimum conditions of supercritical CO2 extraction of Xiaoyaosan, and establish its fingerprint by gas chromatography-mass spectrometry (GC-MS), the yield of extract were investigated, an orthogonal test was used to quantify the effects of extraction temperature, pressure, CO2 flow rate and time, and fingerprint analysis of different batches of extracts were by GC-MS. The optimal extraction conditions were determined as follows: extraction pressure 20 MPa, extraction temperature 50 degrees C, CO2 flow rate 25 kg x h(-1), extraction time 3 h, and average yield 2.2%. The GC-MS fingerprint was established and 27 common peaks were found, whose contents add up to 81.89% of the total peak area. Among them, 21 compounds were identified, accounting for 53.20% of the total extract. The extraction process is reasonable and favorable for industrial production. The GC-MS method is accurate, reliable, reproducible, and can be used for quality control of supercritical CO2 extract from Xiaoyaosan.

Journal of Experimental Hematology 2012;20(3):792-795
The effects of conventional treatment for myelodysplastic syndrome (MDS) are not remarkable to date, while only a minority of patients was eligible for allogeneic stem cell transplantation. As epigenetics plays a significant role during the occurrence and development of MDS, and histone deacetylase inhibitors (HDACI), a class of gene expression modulating drugs, are currently being developed for therapy of several types of solid tumor, more attention is paying to HDACI as potential therapy of MDS. This review summarizes briefly the rationale for HDACI use in MDS, the common mechanism of HDACI, the present state of the clinical efficiency, and future development in this field.

OBJECTIVETo investigate the effects of Tangzhiping Granule (TZPG) on blood lipids and free fatty acids (FFA) in rats with insulin resistant diabetes (IRD).
METHODSA blank control group consisted of randomly selected normal rats was set up. The remaining rats were established to IRD model by high-fat high-sugar diet feeding and streptozotocin injection. Then the 32 successfully modeled rats were randomized into the model group (treated by saline), the Tangmaikang group (treated with Tangmaikang Granule 1.35 g/kg), and the two TZPG groups treated with high dose (2.70 g/kg) and low dose TZPG (1.35 g/kg) respectively through intragastric infusion for 4 weeks. The body weight (BW), fasting blood glucose (FBG), insulin (INS), blood lipids including triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), and FFA were detected, and the insulin sensitivity index (ISI) calculated.
RESULTSCompared with the blank control group, BW, FBG and INS increased while ISI decreased in the model group (P < 0.05 or P < 0.01). All the above-mentioned abnormal indices were improved in the three treated groups (Tangmaikang, high and low dose TZPG group), but the improvements in the high dose TZPG group were more significant than those in the other two groups (P < 0.05 or P < 0.01). Similar outcomes were also seen in blood lipids detection, in which TG, TC, LDL-C and FFA were higher and HDL-C were lower in model rats than those in blank controls, they were improved in the three treated groups (P < 0.05), and the best improvements were seen in the high dose TZPG group (P < 0.05).
CONCLUSIONTZPG could reduce levels of BW, FBG, INS, TC, TG, LDL-C and FFA, and increase levels of ISI and HDL-C in rat model of insulin resistant type 2 diabetes, so as to improve the insulin resistance in them.

OBJECTIVETo investigate if the duration from poisoning to treatment (no treatment period) is related to the prognosis of patients with severe acute organophosphorus pesticide poisoning (SAOPP).
METHODSOne hundred and seventy-four patients with the pre-hospital systematic treatment served as the treatment group while 160 patients going to the hospital by themselves without treatment or rejecting gastrolavage served as the control group. Patients in both groups were treated by gastrolavage, pralidoxime chloride, atropine and other expectant treatment. The duration of no treatment period, death, and severe complication were observed. The time of disappearance of symptoms, the recovery time of acetyl cholinesterase (AChE), atropinization time, atropine dosage, pralidoxime chloride dosage, naloxone dosage, hospitalization days and other targets were also observed.
RESULTSThe duration of no treatment period in treatment group [(1.2 +/- 0.3) h] was significantly shorter than that in control group [(2.8 +/- 0.5) h, (P < 0.01)]. The mortality rate in treatment group was 6.32% while that in control group 22.5% (P < 0.01). The incidence of respiratory failure, heart injury, brain injury, atropine poisoning, intermediate syndrome, liver injury in treatment group (12.64%, 5.75%, 8.62%, 1.72%, 4.60%, 5.17% respectively) were lower than those in control group (25.63%, 13.75%, 17.50%, 6.25%, 7.50%, 9.38% respectively, P < 0.05 or P < 0.01). The time of symptoms disappearance, the recovery time of AChE, atropinization time, atropine dosage, pralidoxime chloride dosage, naloxone dosage, hospitalization days in treatment group were significantly superior to those in control group (P < 0.05 or P < 0.01).
CONCLUSIONThe pre-hospital systematic treatment can improve the prognosis of the patients with SAOPP, which is worth popularizing and using.
