In recent years, the incidences of male infertility and recurrent abortion are increasing. The causes of the conditions are varied and complex, but the affected stability of the genetic material in the sperm is an important etiological factor. Environmental pollutants may invade the body through respiration, diet and other channels, resulting in infertility and abortion or even affecting the reproductive system development of the offspring by changing the epigenetics of sperm DNA. In this paper, we propose the idea of using traditional Chinese medicine to prevent environmental pollutant-induced epigenetic changes of sperm DNA, hoping to provide a new insight into the protection against genetic material damage, male infertility, and recurrent abortion caused by environmental pollutants.

Source data and its source documents are the foundation of clinical research. Proper source data management plays an essential role for compliance with regulatory and GCP requirements. Both paper and electronic source data co-exist in China. Due to the increasing use of electronic technology in pharmaceutical and health care industry, electronic data source becomes an upcoming trend with clear advantages. To face new opportunities and to ensure data integrity, quality and traceability from source data to regulatory submission, this document demonstrates important concepts, principles and best practices during managing source data. It includes but not limited to: (1) important concepts of source data (e.g., source data originator, source data elements, source data identifier for audit trail, etc.); (2) various modalities of source data collection in paper and electronic methods (e.g., paper CRF, EDC, Patient Report Outcomes/eCOA, etc.); (3) seven main principles recommended in the aspect of data collection, traceability, quality standards, access control, quality control, certified copy and security during source data management; (4) a life cycle from source data creation to obsolete is used as an example to illustrate consideration and implementation of source data management.

Objective In order to explore the roles of TLR2 and TLR4 in the hepatocyte dam- age caused hy hepatitis B virus infection,and to find whether LPS can affect the damage of hepato- cytes pre-and pos-HBV infection,we detected the changes of TLR2 and TLR4 expressions in hu- man hepatocyte lines HepG2 cells and 2.2.15 cells.Methods HepG2 ceils are most similar to normal human hepatocytes and 2.2.15 ceils are HepG2 cells infected with HBV.We selected these two cell lines to study the differences of TLR2 and TLR4 expression between HepG2 cells before and after HBV infection.In this research,both HepG2 and 2.2.15 cells were stimulated with 0?g/ml, 1?g/ml,10?g/ml,100?g/ml,1 mg/ml and 10 mg/ml LPS.Then the expression of protein of TLR2 and TLR4 were examined by immuno-histochemistry(IHC).The cnRNA of HepG2 and 2.2.15 ceils stimulated with 0?g/ml and 10 mg/ml LPS were examined by reversal transcription-pol- ymerase chain reaction(RT-PCR).Thereafter,the apoptosis of HepG2 and HepG2.2.15 cells were examined by flow cytometry(FC),and the expressions of HBsAg and HBeAg of HepG2.2.15 cells tested with Abbott kits.Results IHC and RT-PCR analysis revealed that TLR2 and TLR4 expres- sions could he detected in both HepG2 and 2.2.15 cells.Moreover,without immune activation, TLR2 and TLR4 expressions were higher in the presence of higher concentrations of LPS.FC analy sis revealed that no apoptosis detected in HepG2 ceils stimulated with LPS in this research,but apop- tosis could be detected in 2.2.15 cells when treated with the same factors.Furthermore,the apoptosis ratios increased with the increase of LPS concentrations.When concentrations of LPS were 1?g/ml, 10?g/ml,100?g/ml,1 mg/ml and 10 mg/ml,the apoptosis ratios were 1.94%,3.03%,3.50%, 3.72%,5.30%,respectively.Abbott analysis revealed that expressions of HBsAg and HBeAg of 2.2.15 cells stimulated with LPS were lower than those not stimulated with LPS.Conclusion HBV can affect the expressions of TLR2 and TLR4 in HepG2 cell lines.LPS can lead 2.2.15 cells to apop- tosis but not HepG2 cells.Although LPS cannot damage normal hepatocytes,it might aggravate hep- atocytes damage when their microenvironment was changed by HBV infection.

Aim To observe the effect of hemodialysis on pharmacokinetics of sparfloxacin in thepatients contracting chronic renal failure. Methods Sparfloxacin concentrations inserum and urine of hemodialysis and non-dialysis patients were measured with a highperformance liquid chromatography method after administration a single oral dose of 200mg sparfloxacin. The pharmacokinetic parameters were computed with the programPKBP-N1.Results The main pharmacokinetic parameters in hemodialysis group wereT1/2(ka) - (1. 25 ?0. 57) h, T1/2(?) = (11. 88?4. 13) h, Tpeak = (4. 18 ? 0. 78) h,Cmax = (0.80 ? 0. 17) mg? L-1 and AUC0-= (6. 90 ? 3. 25) mg?h?L-1, while innon-dialysis group were T1/ 2(ka) = (1. 12 ? 0. 42) h, T1/ 2(?) = (15. 93 ? 5. 20) h, Tpeak =(3. 88 ? 0. 75) h, Cmax = (0. 69 ? 0. 37) mg?L -1, AUC0-= (10.05 ? 4. 13) mg?h?L-l. The original sparfloxacin discharge rats in urine within 24 h were (8. 98 ? 3. 92) % and(10. 58 ? 5. 64) % separately. T1/2(?) and AUC in hemodialysis group were markedly lowerthan in non-dialysis group (P

In recent years, more and more research shows that the pharmacokinetic parameter of traditional Chinese medicine can be affected by the disease states. It's possible that drug metabolic enzymes, transporters, cell membrane permeability and the change of microbes group could be interfered with physiological and pathological changes, which enables the pharmacokinetics of traditional Chinese medicine in the body to be altered, including the process of absorption, distribution, metabolism and excretion, and then the pharmacokinetic parameters of traditional chinese medicine are altered. It's found that investigating the pharmacokinetic of traditional Chinese medicine in the pathological state is more useful than that of in normal state because the great part of traditional Chinese medicine is mainly used to treat disease. This article reflects the latest research on the pharmacokinetic of traditional Chinese medicine in the disease state such as diabete, cerebral ischemia, liver injury, inflammatory disease, nervous system disorders and fever in order to provide certain reference for clinicians designing reasonable administration dose.

OBJECTIVETo explore the mechanism of Astragalus injection (AI) in repairing mucous membrane by observing its effects on the proliferation, differentiation, migration as well as on intracellular content of ornithine decarboxylase (ODC) and polyamine in rat's small intestinal crypt-like cell line (IEC-6) in vitro.

METHODSAI was added in the IEC-6 cells after they had been cultured for 24 hours. Twelve hours after adding AI, the cells were collected to test the ODC mRNA level, ODC protein, ODC activity and the intracellular content of putrescine. Twenty-four hours after adding AI, the condition of cell proliferation and differentiation was observed. Another group of IEC-6 cells were injured after being cultured for 72 hours, and AI was added, the cell migration was observed at 24 hours, 48 hours and 72 hours after medication.

RESULTSAI could inhibit IEC-6 cell proliferation, promote the cell differentiation, but with no apparent effect on injured IEC-6 cell migratin. AI of 62.5-250 micrograms/ml concentration could increase the ODC mRNA level, as compared with control, the difference was significant (P < 0.05-0.01). ODC activity and intracellular content of putrescine could be gradually increased by AI in a dose-dependant manner. No effect of AI was shown on ODC protein in various dosage of AI groups.

CONCLUSIONAI could promote IEC-6 cell differentiation by means of inducing the ODC activity and biosynthesis of polyamine, but without significant effect on cell migration.

In order to clarify material basis of effective parts of liangxue tongyu prescription, blood-heat and blood-stasis rat model induced by dry yeast was established. The changes of rectal temperature, blood viscosity and plasma viscosity were used to evaluate the cooling-blood and activating-blood effects of liangxue tongyu prescription and its parts. Compared with the model group, the extract from liangxue tongyu prescription, its volatile oil and n-butanol part could significantly reduce rectal temperature (P<0.01), and also reduce blood viscosity and plasma viscosity to various degrees (P<0.01 or P<0.05). So volatile oil and n-butanol part were primarily identified as effective parts of liangxue tongyu prescription. By using GC-MS with normalization method of area to analyze volatile oil of liangxue tongyu prescription, 70 compounds were identified, accounting for about 92.54%, mainly as β-asarone, paeonol, α-asarone and shyobunone. 42 compounds such as peony glycosides, tannins, and iridoid glycosides were identified by HPLC-MS techniques and standard comparison. The study determined the effective parts of liangxue tongyu prescription and clarified the chemical composition providing the foundation for further studies on material basis of liangxue tongyu prescription.
