Kaempferiae Parviflorae Rhizoma is the dried rhizome of Kaempferia parviflora in Zingiberaceae. It is originated and widely distributed in Thailand and other tropical and subtropical regions, where it has been used as food and medicine for thousands of years. K. parviflora is also planted in Yunnan and other places of China, but its traditional Chinese medicine properties are not clear, which greatly limits its compatibility with traditional Chinese medicines. In this article, the English and Chinese literatures of K. parviflora were searched from Web of Science, PubMed, Scopus, CNKI, Wanfang, and VIP databases for research and analysis. The medicinal properties of K. parviflora were preliminarily discussed based on the theory of traditional Chinese medicine under the guidance of clinical application and research literatures. The traditional Chinese medicine properties of K. parviflora were inferred as follows: flat, acrid, sweet. The channel tropisms of K. parviflora included kidney, spleen, stomach, and liver. The function of K. parviflora included tonifying kidney to strengthen essence, tonifying Qi and invigorating spleen, soothing liver and relieving depression. K. parviflora was clinically applied for the diseases such as syndrome of kidney essence deficiency, sex apathy, deficiency of spleen Qi, lassitude and asthenia, a weary spirit, obesity, diabetes, liver Qi stagnation, depression, and restless. The equivalent of dry power is 1.5 g·d~(-1) and the equivalent of decoction is 1.5-6 g·d~(-1). The determination of traditional Chinese medicine properties of K. parviflora has indeed laid a theoretical foundation for its application in the field of traditional Chinese medicine and enriched traditional Chinese medicine resources.

Myrtus communis is a traditional medicinal aromatic plant in the Mediterranean. At present, the plant has been introduced and cultivated in the southern part of China, and it is mostly used for ornamental or cosmetic purposes. Based on literature analysis and the theory of Chinese medicine, we discussed the medicinal parts and properties of M. communis in this paper to provide a theoretical basis for exploring the medicinal value of M. communis and its compatibility with traditional Chinese medicines. Literatures were searched from Web of Science(core collection), PubMed, CNKI, VIP and Wanfang by using the set conditions as key words. Then the obtained literatures were screened and classified. Finally, a total of 376 articles were included, consisting of 44 reviews, 54 germplasm resources, 78 chemical researches, 48 studies on application, extraction, or quality, 18 human trials, 132 pharmacological studies, and 2 safety studies. Based on literature analysis and theories of Chinese medicine, the leaves of M. communis were finally selected as the medicinal part of Chinese medicine, and the traditional Chinese medicine properties of M. communis leaves were deduced as pungent, bitter, and cool. The channel tropisms of M. communis leaves included lung, liver, and large intestine, with functions of detoxifying, resolving a mass, and insecticide. It was used for mouth sores, vaginal itching, hemorrhoids and warts, etc.; appropriate amount shall be applied for external use, and the decoction form shall be used for washing the affected parts; 3-12 g equivalent product shall be used in decoction, and this herb shall be put into the decoction in a later stage. The clarification of the medicinal parts of M. communis, and the determination of the Chinese medicine properties of M. communis leaves would lay a theoretical foundation for its compatibility and application with Chinese medicines, and can do more contribution to the medical and healthcare industry in our country.

Objective@#To investigate the association of poor vision with time spent in outdoor activity among students from primary and middle schools, as well as from universities in Guangzhou, so as to provide targeted scientific basis for prevention and control of low vision.@*Methods@#According to the requirements of National Monitoring of Common Diseases and Health Risk Factors among Students Manual, a total of 2 908 students were selected in 1 urban area and 1 suburban county for monitoring and investigation in Guangzhou.@*Results@#The poor vision rate was 69.2% among students in Guangzhou, with girls (74.4%) > boys (64.2%), suburban country (76.3%) > urban areas (54.1%), university (95.0%) > vocational high school (82.5%) > regular high school (81.1%) > junior high school (73.4%) > primary school (45.6%). With the exception of primary students, the severe poor vision has the largest proportion in each age group. The proportion of spending less than 1 or 2 h for outdoor activities per day: girls>boys, suburban country > urban area, university and regular high school are higher. The poor vision rate of students who spent <2 h(72.3%) for outdoor activities daily was higher than those spent ≥2 h(65.6%). Compared with students who spent ≥2 h/d for outdoor activities, those spent < 2 h/d were at 1.24 times risk of being low vision(OR=1.24, 95%CI=1.04-1.48), controlling for the available confounders.@*Conclusion@#Poor vision rate of students in Guangzhou is high, occurring mainly with severe impairment and in younger age, the daily outdoor activity time is low. Girls, students from suburban country and junior high school should be considered as the emphasis for prevention and control of low vision.

The first genetic linkage map of Salvia miltiorrhiza was constructed in 94 F1 individuals from an intraspecific cross by using simple sequence repeat (SSR), sequence-related amplified polymorphism (SRAP) and inter-simple sequence repeat (ISSR) markers. A total of 93 marker loci in the linkage map, consisting of 53 SSR, 38 SRAP and 2 ISSR locus were made up of eight linkage groups, covered a total length of 400.1 cm with an average distance of 4.3 cm per marker. The length of linkage groups varied from 3.3 -132 cm and each of them included 2-23 markers, separately. The result will provide important basis for QTL mapping, map-based cloning and association studies for commercially important traits in S. miltiorrhiza.

<p><b>OBJECTIVE</b>To compare effects of valsartan and benazepril on erythropoietin (EPO) levels in essential hypertensive patients with normal renal function.</p><p><b>METHODS</b>Sixty essential hypertensive patients were randomly divided into valsartan group (n=30, valsartan 80 mg/day) and benazepril group (n=30, benazepril 10 mg/day). Plasma EPO and hemoglobin (Hb) levels were measured at the start of and at 4 and 8 weeks during the treatments.</p><p><b>RESULTS</b>EPO and Hb levels were all in normal range in the two groups. Valsartan decreased EPO levels from 14.179∓3.214 U/L (baseline) to 12.138∓2.926 U/L (P<0.05) and Hb levels from 144.32∓13.84 g/L (baseline) to 135.16∓14.78 U/L (P<0.05). Benazepril treatment did not resulted in any obvious changes in EPO or Hb levels (P>0.05).</p><p><b>CONCLUSION</b>Valsartan may lower EPO and Hb levels in patients with essential hypertension, while benazepril does not have such effects. The safety of valsartan in anemic hypertensive patients should be further investigated.</p>

Chronic myelogenous leukemia (CML) is a clonal myeloproliferative disease of transformed hematopoietic progenitor cells. The expressions of JunB and CDH13 (cadherin-13) gene as tumor suppressor gene were inactivated by promoter methylation in CML patients. This study was purposed to investigate the methylation difference of JunB and CDH13 gene promoter and the expression levels of JunB and CDH13 gene in CD34(+)CD38(-) cells in CML patients vs normal individuals. CD34(+)CD38(-) cells from 8 cases of CML and 5 normal individuals were selected by flow cytometry. The methylation status of JunB and CDH13 genes were detected by MS-PCR in selected CD34(+)CD38(-) cells. The expression levels of JunB and CDH13 gene was detected with real time polymerase chain reaction (RT-PCR). The results showed that no methylation of JunB and CDH13 gene was detected in CD34(+)CD38(-) cells of 5 normal individuals. Methylations of JunB and CDH13 promoter were found in 87.5% (7/8) and 50% (4/8) CML CD34(+)CD38(-) cells, percentages of which were significantly higher than those in normal individuals. The difference was statistically significant (p < 0.05). The relative expression levels of JunB and CDH13 mRNA in CD34(+)CD38(-) cells of CML patients were significantly lower than those in normal individuals (2(-DeltaDeltaCT) were 1/5.21 and 1/10.63 respectively). It is concluded that the high methylation of JunB and CDH13 gene promoter occurs in CD34(+)CD38(-) cells of CML patients, their mRNA expression level is significantly lower, thus the methylation of JunB and CDH13 gene promoter probably plays a role in the pathogenesis of CML and may have clinical significance in predicting prognosis of CML.
