Objective To compare the efficacy of liver preservation in SX-1 solution,HC-A solution and UW solution in the two-cuff technique orthotopic liver transplantation model in rats.Methods We confected SX-1 solution using of aseptic technique and built up two-cuff technique orthotopie liver transplantation model in rats.The SX-1 solution,UW solution and HC-A solution preserved rats livers in 2 h,8 h and 24 h,then went orthotopic liver transplantation.The various hepatic indices were determined when the rats survived for 6 hours after the operation.Results For the ALT,AST,the SX-1 solution group(2 h,8 h,24 h)and UW solution group went up synchronously,there was no statistical significance,(P＞0.05).Compared with HC-A solution group the SX-1 solution group (2 h,8 h,24 h)has already shown the statistical signifcance(P＜0.05).For the LDH,the SX-1 solution group (2 h,8 h,24 h)and HC-A solution group went up synchronously,there was no statistical significance(P＞0.05).Compared with UW solution group the SX-1 solution group(2 h,8 h,24 h)has already shown the statistical significance(P＜0.05).For the number of liver with bile production,each group didn1 show the statistical significance (P＜0.05).The time of preserving liver increased with the number of liver with bile production reducing.Conclusions Confirmed by the orthotopie liver transplantation model in rat,the SX-1 solution is the same as the UW solution in the indices of hepatic enzymologists.exceeding the HC-A solution.The SX-1 solution is the same as HC-A solution and UW solution in the number of liver with bile production.

Luteinized unruptured follicle syndrome (LUFS), a specific type of ovulation disorder, is for a cause of female infertility. Acupuncture therapy has a good effect for LUFS. In order to understand the clinical effects and research situation of acupuncture therapy for LUFS, the author analyzed and reviewed the relevant literature. It was indicated by the findings that acupuncture therapy and integrative therapy of acupuncture and Chinese herbs have good therapeutic effect for this disease. Acupuncture therapy has the effect to promote ovulation. By the therapeutic principle to tonify the kidney and circulate blood, acupuncture therapy mostly was adopted in the period of ovulation. The acupoints are mostly selected from the lower abdomen and lower limbs, possibly based upon syndrome differentiation at the same time. The needling techniques are of certain characteristics. But, the issues of low quality, un-standardized inclusive, exclusive criteria and effective criteria still exist in the current clinical study.

Objective: To investigate the effect of normoxic acidosis on HIF-1α protein expression and activity in human liver cancer cell line HepG2, so as to assess the role of acidosis in tumor growth. Methods: HepG2 cells were cultured in vitro; the cell growth was assessed by MTT assay after exposure to normoxic acidosis culture media (AP, pH 6.5) for 20 h, and the results were compared with those of the control cells (SD, pH 7.2). Nuclear extractions were performed in the cultured cells, and HIF-1α protein level and HIF-1 DNA binding activities were examined by immunocytochemistry, Western blotting, and HIF-1α Transcription Factor Assay Kit (TransAM™). The protein level of VEGF (vascular endothelial growth factor) was detected in whole cell extractions by Western blotting assay. Results: MTT assay demonstrated that the cell survival rate was (98.71±1.79)% after treatment with normoxic acidosis culture media (AP, pH 6.5). In comparison with SD group, we noted a slight decrease of cell viability in AP group (P>0.05). Western blotting analysis showed that the levels of HIF-1α and VEGF protein increased by (9.34±1.67) folds and (3.42±0.83) folds, respectively (P<0.01). Moreover, normoxic acidosis greatly enhanced HIF-1α DNA-binding activity compared to SD groups (P<0.01). Conclusion: Normoxic acidosis can evidently increase HIF-1α protein level and DNA binding activity in HepG2 cells. Furthermore, the protein level of VEGF, an important target gene of HIF-1, is also increased. Therefore it is suggested that, in addition to hypoxia, acidosis may also play an important role in induction of HIF-1 in cancer.

Objective To investigate the accuracy of liver volume measurement in patients with primary hepatocellular carcinoma by using the 3D + medical imaging visualization processing system. Methods Thirty patients who were clinically diagnosed as primary hepatocellular carcinoma and underwent surgical resection before preoperative assessment were selected from January 2016 to November 2016. Preoperative thin-slice CT images were transferred into the 3D + medical imaging visualization processing system for hepatic volume measurement, the predictive resection volume were measured and statistically analyzed with that of intraoperative specimen according to water measurement method. Results All patients had complete resection of tumor, the average volume of predictive resection calculated by the 3D software was (408.84 ± 177.07) ml, the average volume of intraoperative specimen measured by the water test was (399.95 ± 176.15) ml, the difference was not statistically significant (t=1.502, P=0.144), and the average percentage error was (6.21 ± 4.73) %. Pearson correlation analysis showed that there was significant correlation between them (r=0.983, P<0.05). Conclusion 3D+medical image visualization processing system is a simple, intuitive and accurate method for liver volume measurement, which can provide the basis for the accurate measurement of liver volume and the implementation of complex hepatectomy, and guide the precise hepatectomy.

The secondary development of traditional Chinese medicines (TCMs) is an important content of TCM modernization process, as well as an important path for developing new TCM drugs. Under the guidance of the system theory, in response to the lack of the overall guideline and practical methods for the secondary development of TCMs at present, we introduced the overall thought of the secondary development of major TCM varieties, as well as the roles and contents of clinical research, pharmacology and pharmaceutics in the process of the secondary development of major TCM varieties, so as to provide systematic strategies and methods for the development of major TCM varieties.

The secondary development of major traditional Chinese medicine varieties is one of important links during the modernization, scientification and standardization of traditional Chinese medicines. How to accurately and effectively identify the pharmacodynamic material basis of original formulae becomes the primary problem in the secondary development, as well as the bottleneck in the modernization development of traditional Chinese medicines. On the basis of the existing experimental methods, and according to the study thought that the multi-component and complex effects of traditional Chinese medicine components need to combine multi-disciplinary methods and technologies, we propose the study thought of the material basis of secondary development of major traditional Chinese medicine varieties based on the combination of in vivo and in vitro experiments. It is believed that studies on material basis needs three links, namely identification, screening and verification, and in vivo and in vitro study method corresponding to each link is mutually complemented and verified. Finally, the accurate and reliable material basis is selected. This thought provides reference for the secondary development of major traditional Chinese medicine varieties and studies on compound material basis.
