Literatures on pain intervention with transcutaneous electrical acupoint stimulation (TEAS) were collected by searching the databases both in Chinese and English, and summarized to understand the research progress of TEAS effects on pain mediators in recent years. This will provide a more objective and scientific theoretical basis for clinical practice of TEAS to treat pain syndrome, thus promoting the clinical application of TEAS. Our literature analysis indicated that TEAS effectively regulated the release levels of various pain factors such as prostaglandin, 5-hydroxytryptamine, interleukins, substance P and tumor necrosis factor-α to achieve the analgesic effects by affecting the conduction pathways. TEAS is a safe, non-invasive and effective treatment for pain syndrome. However, further research is necessary due to the lack of rigor of the current clinical trial design.

In this paper, Fourier transform infrared spectroscopy fingerprint analysis of Marsdenia tenacissima samples was used to develop a reliable method of tracing the geographical origins. Forty-eight samples from four provinces of China were analyzed by FTIR. We analyzed and characterized the fingerprints in both the full spectrum peaks and characteristic peaks, then the principal component analysis and the cluster analysis were carried out. The results of fingerprint analysis, correlation analysis, principal component analysis and cluster analysis can identify the geographic origins correctly, which verified and supplemented each other; the identification results and the actual location showed a high degree of consistency, namely the lower the space distance, the greater the similarity of different samples. These results revealed the obvious superiority and practical value in comparison to the more tedious and time-consuming wet chemistry method normally used. Using appropriate metrology methods can trace the geographical source correctly. The M. tenacissima materials from the region of Maguan should be considered as genuine medicinal materials taking into account the good quality.

In order to establish the stable andreliable ISSR-PCR System of Lysimachia christinae, L16 (4(5)) orthogonal design, which based on 7 levels of single factor experiment, were used in this study. The variance analysis was carried out by SPSS 19.0, and 5 main factors affecting the reaction system were optimized in 4 levels. The best annealing temperature was selected by the optimized reaction system. And the stability and reliability of this system was tested by 23 samples from different origins. The results showed that the five factors (DNA template, primer, dNTP, Mg2+ and Taq enzyme) were the most impacts on the amplified results of ISSR-PCR of L. christinae. The order of the influence was: primer > Taq enzyme > DNA template > Mg2+ > dNTP. The optimal system, which was determined by multiple comparison on different levels of each factor, was total volume of 25 microL, including DNA template 60 ng, primer 0.3 micromol x L(-1), dNTP 0.2 mmol x L(-1), Mg2+ 1.8 mmol x L(-1), Taq enzyme 1.25 U. The optimal system was stable and reliable tested by 23 samples from different origins. This study lays the foundation for genetic diversity analysis, fine varieties selection and molecular identification of L. christinae, and provides reference for optimization on ISSR-PCR system of other speciesin future.

An autopsy case of sudden death induced by alimentary tract hemorrhage was presented, which was caused by the unexpected rupture of clinically unrecognized tuberculous abdominal aortic aneurysm (TAAA). The initial diagnosis was made of the syndrome of coronary heart disease and hypertensive disease. The detailed autopsy showed that the alimentary tract hemorrhage was caused by a sudden rupture of the mass after posture changing was ascertained as the cause of death. The diagnosis of TAAA was determined by the autopsy findings. Analysis for the medical dispute of TAAA was described, and the difficulty of the diagnosis and medico-legal implications were also discussed.

OBJECTIVETo investigate the regional anatomy of the inguinal region and abdominal ring and provide accurate anatomic basis for the clinical application of total peritoneum intraperitoneal onlay mesh (TPIPOM).
METHODSThe structures of the inguinal region and those surrounding the abdominal ring of 18 cadavers (11 males and 7 females, 36 sides) were dissected to measure the lengths from the nerves and vessels to the corresponding anatomical landmarks.
RESULTSThe average distances from the point where the iliohypogastric nerve (IHN) ran through the obliquus internus abdominis to anterosuperior iliac spine and from the point where the IHN ran through the aponeurosis of the external oblique muscle of the abdomen to the superior margin of the symphysis pubica were 4.10±0.89 cm and 5.02±1.46 cm, respectively. The average distances from the point where the ilioinguinal nerve (IGN) ran through the obliquus internus abdominis to the anterosuperior iliac spine and from the point where IGN ran through the aponeurosis of the external oblique muscle of the abdomen to the superior surface of the tuberculum pubicum were 3.09±0.81 cm and 3.84±0.89 cm, respectively. We established the regional anatomy model of the structures surrounding the abdominal ring.
CONCLUSIONThe quantitative measurement of important structures of the inguinal region and establishment of the regional anatomy model of the surrounding structures of the abdominal ring can provide a valuable reference to reduce intraoperative and postoperative complications of TPIPOM.

OBJECTIVETo investigate the effect of iodine-125 implantation on immune cell subsets and cytokine production in patients undergoing hepatocellular carcinoma (HCC) resection.
METHODSSixty-eight patients with resectable HCC were randomly divided into intrahepatic iodine-125 embedding group and control group. The percentages of T lymphocyte phenotypes (CD3(+), CD4(+), CD8(+)), NK cells, and the plasma concentrations of IL-4, IL-10, IL-12 and IFN-gamma of the patients were determined with flow cytometry and ELISA, respectively.
RESULTSIn the control group, the postoperative CD3(+) and CD4(+) immunocytes were (39.38-/+6.98)% and (24.34-/+3.18)%, significantly lower than the preoperative levels [(62.58-/+8.67)% and (30.63-/+4.19)%, respectively, P<0.05)]. The postoperative concentrations of IL-4 and IL-10 were (29.83-/+7.99) and (87.54-/+2.89) ng/L, significantly higher than the preoperative levels (10.35-/+8.76 and 64.25-/+2.54 ng/L, respectively, P<0.05). In the treatment group, the percentages of the immunocytes and cytokine concentrations underwent no significant changes after the operation, but postoperative IL-12 (89.46-/+11.43 ng/L) and IFN-gamma (47.78-/+5.45 ng/L) levels were significantly higher than the preoperative levels (36.13-/+9.16 and 7.14-/+2.17 ng/L, respectively, P<0.05). Significant differences were found between the two groups in the postoperative CD3(+) and CD4(+) immunocytes and IL-4, IL-10, IL-12 and IFN-gamma levels.
CONCLUSIONIodine-125 implantation can strongly stimulates the anti-tumor immune response in HCC patients by increasing CD3(+) and CD4(+) immunocytes and promoting Th2/Th1 deviation.

The proteins encoded by the Brassica juncea chitinase gene BjCHI1 and its derived genes BjCHI2 and BjCHI3 were expressed by Multi-copy Pichia expression system. The chitinase activity of FPLC purified BjCHI1, BjCHI2 and BjCHI3 were tested and the results showed that all the three proteins degraded both CM-chitin-RBV and colloidal chitin. The Km values of BjCHI1, BjCHI2 and BjCHI3 for CM-chitin-RBV were estimated as 0.799 mg/mL, 0.544 mg/mL and 0.793 mg/mL, respectively. When the colloidal chitin was used as substrate, the Km values were 0.281 mg/mL, 0.388 mg/mL and 1.643 mg/mL, respectively, indicating chitin-binding domain can increase affinity of chitinase to insoluble substrate. In the agglutination activity assay, only BjCHI1 shows activity when the protein concentration was more than 33 micrograms/mL, while BjCHI2 and BjCHI3 without agglutination activity even when the concentration was increased as high as 800 micrograms/mL. This means that the two chitin-binding domains in BjCHI1 are essential for agglutination and BjCHI1 is the first protein which shows both chitinase and agglutination activity identified so far in plants.
