Objectives : This study investigated oriental diagnosis and treatment of reflex esophagitis (RE) such as syndrome differentiation and herbal medicine by reviewing Chinese journals. Methods : A journal search was performed using China National Knowledge Infrastructure (CNKI) from January 2006 to December 2010. The keywords were the various combinations of 'reflex esophagitis', 'Chinese medicine', 'syndrome differentiation', and 'herbal medicine'. All types of journal entries that explained or referred to herbal medicines and definite syndrome differentiations were included. The Types of the journals were randomized clinical trials (RCT), reviews, essays, case series and reports. Vague syndrome differentiations and experimental studies were excluded. Selected journals were extracted and summarized by two researchers independently. Results : 47 Chinese entries were finally selected. 61% of them were case-control trials that had non-randomized, active controlled clinical trials. 36 kinds of syndrome differentiations about RE were investigated. We summarized and divided them into 10 syndrome differentiation groups. 肝胃不和(syndrome of liver qi invading the stomach) in syndrome differentiation, 和胃降逆 (harmonize the stomach and direct qi downward) in method of treatment, and Jwa kum-whan (左金丸) were cited with high frequency in RE. Conclusions : We find that many kinds of syndrome differentiation groups and herbal medicines for reflex esophagitis are used in China, compared with Korea. Further studies will be required about oriental syndrome differentiation and treatment of this disease.

Introduction Jaundice is one of the most common conditions found in neonatal period. Phototherapy is one of the main treatments for neonatal jaundice. However, several adverse effects of the phototherapy have been reported, including DNA damage recently. Therefore, a variety of treatments have been conducted to shorten the duration of phototherapy. Meanwhile, it has been hardly tried to prevent neonatal jaundice, but diverse approaches have been tried in traditional Chinese medicine (TCM) for many years. Therefore, this study aims to analyze the studies for the treatments to prevent neonatal jaundice based on TCM. Materials and Methods Various literatures have been searched via CNKI, and PubMed using the terms "neonatal jaundice" (新生儿黄疸, 胎黃, 胎疸) in category of 'Traditional Chinese Medicine', 'Traditional Chinese Medicinal Herbs' and 'Combination of Traditional Chinese Medicine With Western Medicine'. The search range included randomized controlled trials (RCTs), controlled clinical trials (CCTs), case reports, reviews and animal experiments published from 2013 to 2015. Results A total of 104 studies were found. 93 articles were excluded by reviewing the titles and abstracts. Out of the remaining 11 studies, 9 articles were RCTs, 2 articles were CCTs. The treatment used in neonatal babies in the studies were, using herbal remedies (meditation 5, bath 3 and retention enema 1) and the acupressure. All treatments were initiated within the first 24-48 hours after their birth. Then, there was a study that the subjects taken the herbal medicine were women during pregnancy. The outcome assessments used were the serum total bilirubin (TB), transcutaneous bilirubin measurement (TCB), the incidence of the hyperbilirubinemia, the duration time of the jaundice. Especially, TB, TCB and the incidence of the hyperbilirubinemia have decreased significantly more than that of the control group in the most of the results. No severe adverse events were reported in all articles reviewed. Conclusions Conventional treatment such as, herbal medicine in TCM, seems to be the effective way to prevent neonatal jaundice or hyperbilirubinemia. Therefore, the conventional treatment may be favorable choice for preventive treatment for neonatal jaundice.

Licorice, a traditional Korean medicinal plant, is recognized for its main active ingredient, glycyrrhizin. The level of glycyrrhizin in Chinese licorice (Glycyrrhiza uralensis) is lower than the reference level (2.5%) set by the Korean Pharmacopoeia, reducing its value as a medicinal herb. In this study, we aimed to overcome this problem by generating an interspecific licorice hybrid by crossing European licorice (G. glabra) with Chinese licorice, resulting in the production of 32 $F_1$ lines. A comparison of genetic traits revealed variations in glycyrrhizin content among lines, ranging from 1.5 to 5.6%, with a mean value of 3.2%; these values are higher than that of the parental plants. Additionally, 25 lines (78.1%) had a glycyrrhizin content greater than 2.5%, which is higher than the reference level set by the Korean Pharmacopoeia. Four of these lines had glycyrrhizin levels higher than the WHO recommended level of 4.0%. A comparison of phenotypic characteristics showed that the leaves of the hybrids possessed all of the characteristics of European and Chinese licorice; however, the stems of most hybrids had characteristics of European licorice. Finally, we determined the genetic distances of 34 samples of Glycyrrhiza plants (parents, 32 $F_1$ lines) by random amplified polymorphic DNA (RAPD); the $F_1$ lines showed a close genetic distance. We plan to develop to a cultivar using five of these lines (glycyrrhizin content < 4.0%).

Leaves from Panax ginseng Meyer (Korean origin and Chinese origin of Korean ginseng) and P. quinquefolius (American ginseng) were harvested in Haenam province, Korea, and were analyzed to investigate patterns in major metabolites using HPLC-based metabolic profiling. Partial least squares discriminant analysis (PLS-DA) was used to analyze the the HPLC chromatogram data. There was a clear separation between Panax species and/or origins from different countries in the PLS-DA score plots. The ginsenoside compounds of Rg1, Re, Rg2, Rb2, Rb3, and Rd in Korean leaves were higher than in Chinese and American ginseng leaves, and the Rb1 level in P. quinquefolius leaves was higher than in P. ginseng (Korean origin or Chinese origin). HPLC chromatogram data coupled with multivariate statistical analysis can be used to profile the metabolite content and undertake quality control of Panax products.

Objectives: The purpose of this study is to review the trend of chinese clinical studies of herbal treatment for infertility caused by Polycystic Ovary Syndrome (PCOS). Methods: We searched the clinical studies published from 1979 to 2013 through CAJ (Chinese Academic Journal) with keywords of "PCOS and 不孕" or "多囊卵 巢綜合證 and 不孕". We analyzed the intervention type of clinical studies. In addition, We researched randomized controlled trials (RCTs) published from 2009 to 2013, assessed the quality of RCTs using the Jadad Scale and reanalyzed the intervention type of RCTs. Results: One hundred and seventeen clinical studies were finally selected. Clinical studies of herbal treatment for infertility caused by PCOS increased remarkably after the 2000s in China. Combined herbal medicine and western medicine was used the most frequently. RCTs published from 2009 to 2013 were fifty. Average of Jadad score of RCTs was 1.2. Combined herbal medicine and western medicine was also the most frequently used as intervention in RCTs. Conclusions: Clinical studies on effect of combined herbal medicine and western medicine for infertility caused by PCOS were mostly published in China. But Quality of studies was generally low. Further research on effect of herbal treatment for infertility caused by PCOS is needed.

Herbal medicines have been used worldwide, particularly in the Far East countries, for thousands of years. Herbal medicines comprise complex mixtures of different phytochemical substances, and their nature may vary substantially depending on many factors related to the cultivation condition, area and harvest time. The processing of the herbal medicines significantly affects their pharmacological and toxicological properties. In this paper, we discuss current research that deals with the techniques for processing Chinese herbal medicines. These results will provide a scientific basis for developing new techniques for the processing of herbal medicines.

Clubroot caused by the protist Plasmodiophora brassicae is one of the most destructive diseases of Brassica crops. Developing Chinese cabbage cultivars with durable clubroot resistance (CR) is an important goal of breeding programs, which will require new genetic resources to be identified and introduced. In this study, we evaluated resistance to P. brassicae race 4 using 26 Chinese cabbage (B. rapa ssp. pekinensis ) cultivars compared to the clubroot-susceptible Chinese cabbage inbred line 'BP079' and the clubroot-resistant European turnip (B. rapa ssp. rapifera ) inbred line 'IT033820'. No symptoms of clubroot disease were found in 'IT033820' infected with P. brassicae race 4, whereas the Chinese cabbage cultivars exhibited disease symptoms to various degrees. The Chinese cabbage cultivars that were reported to be clubroot-susceptible were susceptible to P. brassicae race 4; however, seven of the 20 cultivars reported to be clubroot-resistant were susceptible to this race of P. brassicae to varying degrees. Resting spores of P. brassicae were abundant within the infected root tissues of 'BP079', as revealed by light microscopy and scanning electron microscopy (SEM), but they were not detected in root tissues of 'IT033820'. Although resting spores were not detected by light microscopy in root tissues of the clubroot-resistant Chinese cabbage cultivar 'Kigokoro 75', a few spores were observed by SEM. The $F_1$ hybrids from a cross between 'IT033820' and 'BP079' showed no disease symptoms, and all $BC_1P_1$ progenies from a cross between the $F_1$ hybrid and 'IT033820' exhibited a resistance phenotype. In the $BC_1P_2$ population from a cross between the $F_1$ hybrid and 'BP079', this trait segregated at a ratio of 3(R):1(S) (${\chi}^2=1.333$, p = 0.248) at a 5% significance level. Inoculated $BC_1P_2$ plants were either highly resistant or highly susceptible to the pathogen, indicating that the CR to race 4 of P. brassicae carried by 'IT033820' is dominant. In the $F_2$ population, this trait segregated at a ratio of 15(R):1(S) (${\chi}^2=0.152$, p = 0.696) at a 5% significance level, suggesting that CR in 'IT033820' is mainly controlled by two dominant genes. Therefore, 'IT033820' represents a promising genetic resource for developing durable CR breeding lines in Chinese cabbage.

Polygoni multiflori Radix has been used as a tonic medicine. In Korea, Cynanchi wilfordii Radix have been used too. Their names are resembled, but their plant origines are different. Polygoni multiflori Radix is called 何首烏 or 赤何首烏, and Cynanchi wilfordii Radix is 白何首烏 or 白首烏. They are suggested that they had been confused using at the early days in drug history. Polygoni multiflori Radix is enclosed in the pharmacopoeias of Korea, North Korea, Chinese and Japan. The nomina of pharmacopoeias are 赤何首烏 at North Korea and 何首烏 at other countries; Korea, Chinese and Japan. Cynanchi wilfordii Radix is just enclosed in Korea and North Korea. It means that Cynanchi wilfordii Radix has been commonly prescribed in Korea and North Korea than other countries. The nomina of pharmacopoeias are 白首烏 in Korea and 白何首烏 in North Korea. The characteristics of 何首烏 in ancient herbal records are confused of Polygoni multiflori Radix and Cynanchi wilfordii Radix. But Polygoni multiflori Radix is fixed at 何首烏 later. In Korea (south and north) Cynanchi wilfordii Radix has been recorded to using in 東醫寶鑑 that was Korea traditional Medicinal book and wrote at 1613. The 白首烏 is named in chinese about 20 century, but 白何首烏 is in korea about 19 century. In these consequences, prescription of Cynanchi wilfordii Radix in Korea is earlier than Chinese and Japan, and more common consumption too. So the nomen of 白何首烏 is better properly than 白首烏 in Korean Herbal pharmacopoeia.
