In order to study the spectral reflectance differences of Glycyrrhizae Radix under different growth conditions and lay the foundation for quantitative monitoring of Glycyrrhizae Radix remote sensing images, spectra of Glycyrrhiza species under different growth period and different varieties and different regions were measured by a portable spectrometer. The results showed that the reflectivity of annual G. uralensis was obviously higher than that of the two years plant in the visible light band own to the contents of crown layer chlorophyll. The reflectivity of two years G. pallidiflora was higher than that of G. uralensis in the near infrared band own to the leaf area index and the content of leaf water. The red edge spectrum of annual plant fluctuated largely than that of two years plant due to vegetation coverage and leaf area index. G. pallidiflora grew well than G. uralensis. Under different regions of the Glycyrrhiza species, spectral data analysis showed that within a certain range, the average annual precipitation and average annual evaporation were the major factors to affect the differences of Glycyrrhiza species spectral data under different regions owe to the leaf water content, the higher leaf water content, the lower spectral reflectance. The principal component analysis and continuum-removed method of the spectral data under different regions found that, within a certain range, the average annual precipitation and average annual evaporation were the major factors caused by the differences of Glycyrrhiza species spectral data under the different regions, Glycyrrhiza species spectral similarity related to the spatial distance.

A series of cycloberberine derivatives were designed, synthesized and evaluated for their anti-cancer activities in vitro. Among these analogs, compounds 6c, 6e and 6g showed strong inhibition on human HepG2 cells. They afforded a potent effect against DOX-resistant MCF-7 breast cells as well. The primary mechanism showed that cell cycle was blocked at G2/M phase of HepG2 cells treated with 6g using flow cytometry assay. It significantly inhibited the activity of DNA Top I at the concentration of 0.1 mg mL-1. Our results provided a basis for the development of this kind of compounds as novel anti-cancer agents.

OBJECTIVETo evaluate the intervention effect of diet, exercise and Jiangtang Bushen Recipe (JBR, a Chinese herbal recipe) in preventing the progress of patients with impaired glucose tolerance (IGT) to diabetes mellitus (DM) type 2.
METHODSFifty-one patients with IGT, with their diagnosis conformed to the diagnosis standard of WHO, 1999, were randomly divided into the control group (n = 26) and the TCM group (n = 25). Patients in the control group attended to the educational course for DM and received dietotherapy and kinetotherapy, and to those in the TCM group, under these treatments, JBR was given additionally. Oral glucose tolerance test (OGTT), body weight index (BWI), levels of blood lipids and fasting insulin of all the patients were examined after 3 months, 6 months and 12 months of treatment. The total observation time was 1 year.
RESULTSExcept the 6 cases out of the 51 patients (11.7%), on whom the observation discontinued, in the control group, as compared with before treatment, levels of fasting insulin and fasting blood glucose after treatment were not changed significantly (P > 0.05), also insignificant difference was shown in levels of total cholesterol (TC) and triglyceride (TG), though the two indexes lowered slightly after treatment (P > 0.05), but significant difference was shown in comparison of OGTT/2 h, blood glucose and BWI (P < 0.05). While in the TCM group, fasting blood glucose was changed insignificantly (P > 0.05), but there was significant difference in comparison of fasting insulin, TC, BWI, OGTT/2 h and plasma glucose levels (P < 0.01) respectively before and after treatment. At the end of the study, the cumulative cases with conversion to diabetes were 3 (13.6%) in the control group, and 1 (4.3%) in the TCM group, chi 2 test showed insignificant difference in comparison of diabetes conversion rate between the two groups (P > 0.05), however, the TCM group showed a better year conversion rate of normal glucose tolerance than that in the control group (chi 2 = 8.31, P < 0.01).
CONCLUSIONTCM intervention is possibly effective in delaying the conversion of IGT to DM type 2, and plays integrative effeciency in impelling IGT patients to health. The favorable education and treatment of DM controlling, including dieto- and kineto-therapy may also be advantageous in IGT intervention, but could not be effective in blocking the advance of IGT.

OBJECTIVETo observe the millimeter wave therapy responses in patients with burning mouth syndrome.
METHODSEighty patients were randomized divided into 4 groups. The first group was treated with both millimeter wave irradiation and routine medication, the second group with millimeter wave irradiation, the third with pretending millimeter wave irradiation and routine medication and the fourth with routine medication. Pain, extravasated blood level and autonomic nerve system condition were double-blindly evaluated either before or after the treatment.
RESULTSStatistically significant difference (P < 0.05) was found as the degree of pain was compared before and after treatment of all the 4 groups. The first and second group, which were affected by the millimeter wave irradiation, had obvious improvements in the extravasated blood level and autonomic nerve system condition (P < 0.05). When the 4 groups were compared with each other, there were significant differences (P < 0.05) between the first and the fourth groups, and the second and the fourth groups regarding the reduction of pain. According to extravasated blood level, significant differences (P < 0.05) were found in the first and third or fourth groups, the second and third or fourth groups.
CONCLUSIONSThe irradiation of holographic point by millimeter wave can improve the patients' pain, extravasated blood level and autonomic nerve system condition. It might provide a new treatment method for burning mouth syndrome.

OBJECTIVETo study therapeutic effects of comprehensive traditional Chinese medicine therapy for preventing postsurgery stiffness after operation for terrible triad of the elbow.
METHODSFrom December 2008 to December 2013,32 patients with elbow triad were randomly divided into two groups: therapy group and control group. There were 17 patients in control group including 12 males and 5 females with a mean age of (41.0 ± 7.1) years old. The patients in control group were received the past procedure therapy. There were 15 patients in therapy group, including 10 males and 5 females with a mean age of (41.3 ± 7.6) years old. The patients in therapy group were received comprehensive traditional Chinese medicine therapy, including passive exercise training at early stage (0 to 2 weeks after operation), transition from passive to active exercise training at middle stage (3 to 4 weeks after operation), and active exercise training at late stage (5 to 12 weeks after operation). Other treatment methods, such as orally taking or externally use of Chinese herbal medicine, manipulation and physiotherapy, were used at all stages. The Mayo Elbow Performance Score, patient satisfaction and complications were evaluated and analyzed.
RESULTSAll the patients were followed up, and the mean duration was 7.5 months. There were no complications such as internal fixation loosing, obvious displacement fracture and heterotopic ossification occurred. The Mayo score and patient satisfaction in therapy group were higher than those in control group (t = 12.78, P = 0.00; χ2 = 8.719, P = 0.003). Seven patients needed reoperation in control group, compared with 1 patient in therapy group (χ2 = 4.626, P = 0.032).
CONCLUSIONThe comprehensive traditional Chinese medicine therapy is effective to prevent postoperative stiffness after operation for terrible triad of the elbow by using different methods at different stages, which is worthy of spread and application.
