Chemical constituents in Dolomiaea plants and their pharmacological activities: a review / 中国中药杂志

Dolomiaea plants are perennial herbs in the Asteraceae family with a long medicinal history. They are rich in chemical constituents, mainly including sesquiterpenes, phenylpropanoids, triterpenes, and steroids. The extracts and chemical constituents of Dolomiaea plants have various pharmacological effects, such as anti-inflammatory, antibacterial, antitumor, anti-gastric ulcer, hepatoprotective and choleretic effects. However, there are few reports on Dolomiaea plants. This study systematically reviewed the research progress on the chemical constituents and pharmacological effects of Dolomiaea plants to provide references for the further development and research of Dolomiaea plants.

[Textual research on Bambusae Concretio Silicea].

By studying various ancient texts such as herbal classics and medical literature from different eras, it was found that there were discrepancies in the records about Bambusae Concretio Silicea(Tian Zhu Huang). In order to establish an accurate foundation, this research was based on ancient herbal literature and combined with plant morphology and investigative studies to examine its earliest mentions in ancient texts, nomenclature, medicinal properties, indications, and quality assessment standards. In the early records, Bambusae Concretio Silicea was referred to by several different names, such as "Zhu Huang" "Tian Zhu Huang" "Zhu Gao" "Zhu Tang", and "Zhu Huang". The earliest known formal usage of the name "Tian Zhu Huang" was found in the book Ri Hua-zi's Materia Medica(Ri Hua Zi Ben Cao). Throughout various ancient texts, the earliest recorded information about Bambusae Concretio Silicea also appeared in Ri Hua-zi's Materia Medica, not in Materia Medica of Sichuan(Shu Ben Cao) or other ancient texts. Ri Hua-zi's Materia Medica provided relevant descriptions of its origin, medicinal properties, and indications, albeit with some errors due to limited knowledge. However, this has been a valuable starting point for future research on Bambusae Concretio Silicea and holds pioneering significance in forming a mature system. As the research delved deeper, the medicinal properties of Bambusae Concretio Silicea have been consistent since Ri Hua-zi's Materia Medica, and the understanding has gradually improved through years of clinical verification. During the investigation process, the authors found limited records on the quality evaluation of Bambusae Concretio Silicea in ancient texts. Although the information is scarce, it serves as a foundational basis for establishing corresponding quality grading standards for Bambusae Concretio Silicea in the future.

Socioeconomic status influences on bone mineral density in American men: findings from NHANES 2011-2020.

The association between socioeconomic status (SES) and bone mineral density (BMD) in men remains controversial. We showed that SES was positively associated with BMD in American men. Confounding factors like race/ethnicity and age could affect the association. INTRODUCTION: Based on the data from the National Health and Nutrition Examination Survey (NHANES), 2011-2020, this article aims to investigate the association of SES (poverty income ratio (PIR) and education level) with the BMD in American men. METHODS: We evaluated the association of SES with BMD in 4446 men aged ≥ 20 years (mean age, 41.0 ± 13.4 years) from the NHANES 2011-2020. BMD was measured by dual-energy X-ray absorptiometry (DXA) at the lumbar spine. We used multivariate linear regression models to examine the relationship between SES and total spine BMD, adjusted for a large range of confounding factors. RESULTS: Compared with other PIR quarters, individuals in the highest quarter of PIR were more likely to be older and white and had fewer smoking or drinking behaviors. After adjusting for race/ethnicity, age, drinking and smoking behavior, body mass index (BMI), total protein, serum calcium, serum uric acid, cholesterol, serum phosphorus, and blood urea nitrogen, PIR was positively correlated with total spine BMD (ß = 0.004 95% CI: 0.001-0.007, P = 0.006). Individuals with the highest degree (college degree or above) had a 0.057 g/cm2 greater BMD than that of the lowest degree (less than 9th grade) (ß = 0.057 95% CI: 0.037-0.077, P < 0.001). CONCLUSIONS: Our study indicates that SES was positively associated with the lumbar BMD among American men. Clinicians, healthcare providers, and policymakers should consider the unequal SES of men when implementing osteoporosis prevention and treatment strategies.

Application of metabonomics in study of traditional Chinese medicine syndrome:a review / 中国中药杂志

Syndrome is a nonlinear "internal-excess external-deficiency", "dynamic spatial-temporal" and "multi-dimensional" complex system and thus only by using a versatile method can the connotation be expounded. Metabonomics, which is dynamic, holistic, and systematic, is consistent with the overall mode of traditional Chinese medicine(TCM)(holistic view and syndrome differentiation and treatment). Therefore, metabonomics is very important for the research on the differentiation, material basis, and metabolic pathways of syndromes, and efficacy on syndromes. This study reviewed the application of metabonomics in the study of TCM syndromes in recent years, which is expected to objectify the research on TCM syndromes.

Di'ao Xinxuekang alleviates non-alcoholic steatohepatitis in mice by up-regulating Nrf2/HO-1 signaling pathway / 中国中药杂志

The present study investigated the therapeutic effect and mechanism of Di'ao Xinxuekang(DXXK) on non-alcoholic steatohepatitis(NASH) in mice. Sixty-five C57 BL/6 J mice were randomly divided into a normal group and an experimental group for model induction with the high-fat diet for 16 weeks. Then the mice in the experimental group were randomly divided into a model group, an atorvastatin group(4 mg·kg~(-1)·d~(-1)), and high-(200 mg·kg~(-1)·d~(-1)), medium-(60 mg·kg~(-1)·d~(-1)), and low-dose(20 mg·kg~(-1)·d~(-1)) DXXK groups, with 10 mice in each group. Drugs were administered by gavage for eight weeks. Serum lipid, liver lipid, serum alanine aminotransferase(ALT), aspartate aminotransferase(AST), malondialdehyde(MDA), superoxide dismutase(SOD), and glutathione reductase(GSH-Px) were determined. Interleukin-1β(IL-1β) and tumor necrosis factor-α(TNF-α) were measured by enzyme-linked immunosorbent assay(ELISA). The liver index was calculated. The liver pathological change and lipid accumulation were observed by HE and oil red O staining. The liver ultrastructure was observed by the transmission electron microscope. The mRNA and protein expression of nuclear factor-erythroid 2 related factor 2(Nrf2) and heme oxygenase-1(HO-1) was detected by real-time fluorescence-based quantitative PCR and Western blot, respectively. The results showed that compared with the normal group, the model group displayed serum lipid and liver lipid metabolism disorders, elevated transaminase, lipid deposition, steatosis, and inflammation, suggesting that the NASH model in mice was properly induced. Compared with the model group, the DXXK groups showed decreased serum lipid, liver lipid, ALT, AST, MDA, IL-1β, and TNF-α, increased SOD and GSH-Px, alleviated hepatic steatosis, ballooning, and inflammation, and up-regulated Nrf2 and HO-1 gene and protein expression. In conclusion, DXXK can significantly alleviate NASH in mice, which is related to the inhibition of oxidative stress and inflammatory damage by up-regulating the Nrf2/HO-1 signaling pathway.

Effects of total lignans from Eucommia ulmoides barks prevent bone loss in vivo and in vitro.

ETHNOPHARMACOLOGICAL RELEVANCE: The present study systematically investigate the in vivo and in vitro effect of total lignans (TL) extracted from Eucommia ulmoides Oliv. barks on bone formation using ovariectomy rat model and primary cultures of rat osteoblasts. MATERIALS AND METHODS: Eighty 3-month-old female Sprague-Dawley rats were used and randomly assigned into sham-operated group (SHAM) and five ovariectomy (OVX) subgroups, i.e. OVX with vehicle (OVX); OVX with 17α-ethinylestradiol (E2, 25 µg/kg/day); OVX with TL of graded doses (20, 40, or 80 mg/kg/day). The treatment began 4 weeks after the surgery and lasted for 16 weeks. in vitro experiments were performed to determine the potential mechanisms of the anti-osteoporotic effect of TL. RESULTS: Treatment with TL significantly prevent OVX-induced decrease in biomechanical quality of femur such as maximum stress and Young׳s modulus. The mechanical changes were associated with the prevention of a further BMD decrease or even with some improvements in microarchitecture. TL inhibited BMD decrease in the femur caused by OVX, which was accompanied by a significant decrease in skeletal remodeling, as was evidenced by the decreased levels of the bone turnover markers. µCT analysis of the femoral metaphysis showed how to prevent the deterioration of trabecular microarchitecture. TL induced primary osteoblastic cell proliferation and differentiation, inhibition of osteoclastogenesis through an increase in osteoprotegrin (OPG) and a decrease in NF-κB ligand (RANKL) expression in vitro. CONCLUSIONS: We concluded that TL treatment can effectively suppress the loss of bone mass induced by OVX and in vitro evidence suggests this could be through actions on both osteoblasts and osteoclasts.

Protective effects of baicalin against bromocriptine induced abortion in mice.

The Chinese herbal medicine Huang Qin (Radix Scutellariae) had been used for restless fetus for hundreds of years in China, however, little attention had been given to the components of the herb, specifically its ability to exert abortion-preventing effects at the maternal fatal interface. The present study was carried out to investigate the protective effects of baicalin and the possible mechanisms on pregnancies. Baicalin (at 10, 20, and 50 mg/kg BW respectively) was gavaged to bromocriptine-treated mice from gestation day (GD) 1 through GD 7. Abortion rates were calculated and the changes of interferon-gamma (IFN-gamma), interleukin-10 (IL-10) and progesterone were assayed on different gestation days. Results showed that the embryonic death rates were significantly decreased in groups supplemented with 20 or 50 mg/kg BW of baicalin, accompanied with reduced IFN-gamma and enhanced progesterone contents. Moreover, the highest levels of IFN-gamma appeared on GD 5 both in the control and in baicalin treated groups. It is concluded that baicalin can exert an anti-abortive effect by cutting down the production of IFN-gamma and elevating the levels of progesterone in a dose dependent manner and IFN-gamma is involved in an inflammatory reaction which is beneficial for a successful implantation.

[Pulse wave: the bridge connecting traditional Chinese medicine with Western medicine].

Pulse wave, a research focus in both traditional Chinese medicine and Western medicine, which contains a wealth of human physiological and pathological information, has always been the concern of medical practitioners. On the basis of the review on the development of the pulse wave theory and its applications, the existing problems in this field are discussed in this paper. On the basis of the status quo of pulse wave information extraction methods and the utilization of pulse wave in traditional Chinese and Western medicine, a more in-depth study on pulse wave is proposed to make it a bridge connecting traditional Chinese medicine with Western medicine.

Effects of Radix scutellariae and Rhizoma atractylodis on LPS-induced abortion and the uterine IL-10 contents in mice.

In the present study, lipopolysaccharide (LPS) was injected i.v. via the tail vein (0.1 microg per mouse) to induce abortion (embryo resorption) in Kunming mice. The interleukin 10 (IL-10) contents in the uterus were assayed by ELISA. The results revealed that the IL-10 level was significantly decreased in the LPS-induced abortion group of mice compared to the controls. Use of Pentoxifylline (PXF), or a combination of Radix scutellariae and Rhizoma atractylodis reversed the LPS effects: bringing down the fetal resorption rate, and increasing the IL-10 level significantly. The study indicates that the anti-abortive effects of PXF and the combination of Radix scutellariae and Rhizoma atractylodis are closely related to up-regulation of the Th2 cytokine IL-10 at the maternal fetal interface.

Classical and molecular cytogenetic abnormalities in 124 pediatric patients with acute lymphoblastic leukemia / 中华儿科杂志

<p><b>OBJECTIVE</b>In childhood acute lymphoblastic leukemia (ALL), cytogenetics plays an important role in diagnosis, allocation of treatment and prognosis. On the basis of the conventional cytogenetic analysis, molecular methods have improved pediatric hematologists/oncologist's ability to accurately and rapidly perform risk-stratification on patients with childhood ALL during the last few years. The aim of the present study was to assess the demography of cytogenetic abnormalities in childhood ALL.</p><p><b>METHOD</b>The study subjects consisted of 124 newly diagnosed ALL patients younger than 16 years of age, who were diagnosed at the Department of Pediatric Hematology/Oncology, Soochow University Children's Hospital. The diagnosis and FAB subtypes of ALL was determined by Wright-Giemsa-stained bone marrow smears and cytochemical staining. Immunophenotyping of the bone marrow samples was performed by flow cytometry. Multiplex polymerase chain reaction (Multiplex PCR) analysis was performed to detect the 29 most common leukemia translocations for routine molecular diagnostic hematopathology practice, and complement the information gained from conventional cytogenetic analysis.</p><p><b>RESULTS</b>Cytogenetic analysis was successful in 112 of 124 children with ALL. Sixty-eight (60%) of them had clonal chromosomal abnormalities. Numerical imbalances consisted of hyperdiploid (> 47 chromosomes, 36 cases), hypodiploid (< 46 chromosomes, 14 cases), pseudodiploidy (18 cases). Chromosomal translocations were observed in 13 patients by conventional cytogenetic analysis. Three cases were found positive for 4; 11 translocation, 3 cases for 9; 22 translocation, 1 case for 1; 19 translocation and 6 cases for other rare translocations. Multiplex-PCR analysis detected 116 of the 124 ALL patients. Thirteen cases of TEL-AML1, 10 cases of rearrangement in the MLL gene, 4 cases of E2A-PBX1, 4 cases of E2A-HLF, 3 cases of BCR-ABL, 2 cases of TLS-ERG, 32 cases of HOX11 were detected by Multiplex PCR in B-lineage leukemias. SIL-TAL1 had been found in 4 of 7 of T-lineage leukemias.</p><p><b>CONCLUSIONS</b>Sixty-eight cases of ALL showed chromosomal aberrations. Multiplex PCR positivity was detected in 59 (50%) of the 116 ALL patients studied. Multiplex PCR combined with chromosomal analysis uncovered chromosomal abnormalities in 95 of 124 (77%) of ALL patients and supplemented each other in detecting chromosomal abnormalities.</p>

Effects of Tongxinluo-facilitated cellular cardiomyoplasty with autologous bone marrow-mesenchymal stem cells on postinfarct swine hearts / 中华医学杂志(英文版)

<p><b>BACKGROUND</b>Treatment of ischemic heart disease remains an important challenge, though there have been enormous progresses in cardiovascular therapeutics. This study was conducted to evaluate whether Tongxinluo (TXL) treatment around the transplantation of mesenchymal stem cells (MSCs) can improve survival and subsequent activities of implanted cells in swine hearts with acute myocardial infarction (AMI) and reperfusion.</p><p><b>METHODS</b>Twenty-eight Chinese mini-pigs were divided into four groups including a control group (n = 7); group 2, administration of low-dose TXL alone from the 3rd day prior to AMI to the 4th day post transplantation (n = 7); group 3, MSCs alone (n = 7) and group 4, TXL + MSCs (n = 7). AMI models were made by occlusion of the left anterior descending coronary artery for 90 minutes. Autologous bone marrow-MSCs (3 x 10(7) cells/animal) were then injected into the post-infarct myocardium immediately after AMI and reperfusion. The survival and differentiation of implanted cells in vivo were detected by immunofluorescent analysis. The data of cardiac function were obtained at baseline (1 week after transplantation) and endpoint (6 weeks after transplantation) by single photon emission computed tomography (SPECT) and magnetic resonance imaging (MRI). Apoptosis was detected by TUNEL assay and the oxidative stress level was investigated in the post-infarct myocardium at endpoint.</p><p><b>RESULTS</b>At endpoint, there was less fibrosis and inflammatory cell infiltration with more surviving myocardium in group 4 than in the control group. In group 4 the survival and differentiation of implanted MSCs were significantly improved more than that seen in group 3 alone (P < 0.0001); the capillary density was also significantly greater than in the control group, group 2 or 3 both in the infarcted zone (P < 0.0001) and the peri-infarct zone (P < 0.0001). MRI showed that parameters at baseline were not significantly different between the 4 groups. At endpoint, regional wall thickening and the left ventricular ejection fraction were increased while the left ventricular mass index, dyskinetic segments and infarcted size were decreased only in group 4 compared with control group (P < 0.0001). SPECT showed that the area of perfusion defect was significantly decreased at endpoint only in group 4 compared with control group (P < 0.0001). TUNEL assay indicated that TXL administration significantly decreased cell apoptosis in peri-infarct myocardium in groups 2 and 4. Furthermore, superoxide dismutase (SOD) significantly increased and malondialdehyde (MDA) decreased in groups 2 and 4 by the administration of TXL.</p><p><b>CONCLUSIONS</b>Our study demonstrates the following: (1) immediate intramyocardial injection of MSCs after AMI and reperfusion resulted in limited survival and differentiation potential of implanted cells in vivo, thus being incapable of beneficially affecting post-hearts; (2) TXL-facilitation resulted in a significant survival and differentiation potential of implanted cells in vivo via inhibition of apoptosis and oxidative stress, accompanied by significant benefits in cardiac function.</p>
