Objective To observe the effect of Zhuyun Capsule(Pregnant-promoting Capsule)on serum sex hormone and expres- sion of ovarian cytokine of polycystic ovary syndrome(PCOS)rats.Methods Progestogen plus human chorionic gonadotrophin (HCG)was adopted to make PCOS rat models.Totally 40 SD rats were randomized into control group,PCOS model group,Zhuyun Capsule group,and clomiphene citrate group with 10 in each.Radioimmune assay(RIA)was used to measure the sex hormone and immunohistochemical test was done to measure the expression of tumor necrosis factor-?(TNF-?)of ovarian tissue,insulin-like growth factors-1(IGF-1),and leukemia inhibitory factor(LIF)to analyze the relations among these factors.Results Zhuyun Capsule could reduce greatly serum testosterone(T)and luteinizing hormone(LH),decrease expression of TNF-?and IGF-1,but increase expres- sion of LIF.Conclusion Zhuyun Capsule could regulate endocrine function and expression of ovarian cytokine to improve gonad func- tions of PCOS rats and to promote the maturation of follicle and ovulation.

Long-term treatment with an agonist of peroxisome proliferator-activated receptor (PPAR)-γ is associated with bone fractures in the clinical practice. However, the mechanisms underlying the fractures are not fully understood. This study was aimed to examine the effect of rosiglitazone (an agonist of PPAR-γ) of different doses on the proliferation, differentiation, and transforming growth factor beta 1 (TGF-β1)-induced expression of connective tissue growth factor (CTGF) in primary rat osteoblasts in vitro. Osteoblasts were isolated from newly born SD rats and treated with different doses of rosiglitazone (0-20 μmol/L). The proliferation and differentiation of osteoblasts were measured by MTT assay and NPP assay, respectively. The expression of CTGF was determined by RT-PCR and Western blotting. The results showed that most isolated osteoblasts displayed strong alkaline phosphatase (ALP) activity and treatment with different doses of rosiglitazone did not affect their proliferation, but significantly inhibited the differentiation of osteoblasts in a dose-dependent manner. Moreover, treatment with different doses of rosiglitazone significantly reduced the TGF-β1-induced CTGF mRNA transcription and protein expression in a dose-dependent manner in rat osteoblasts. It was concluded that the activation of PPAR-γ may inhibit the differentiation of osteoblasts by reducing the TGF-β1-induced CTGF expression in vitro.

Salvia miltiorrhiza is a traditional Chinese medicine (TCM) and is widely used as a clinically medication for its efficiency in treating cardiovascular disease. Due to TCM is a comprehensive system, the mechanism of S. miltiorrhiza treating cardiovascular disease through integrated multiple pathways are still unclear in some aspects. With the rapid progress of bioinformatics and systems biology, network pharmacology is considered as a promising approach toward reveal the underlying complex relationship between an herb and the disease. In order to discover the mechanism of S. miltiorrhiza treating cardiovascular disease systematically, we use the auxiliary mechanism elucidation system for Chinese medicine, built up a molecule interaction network on the active component targets of S. miltiorrhiza and the therapeutic targets of cardiovascular disease to offer an opportunity for deep understanding the mechanism of S. miltiorrhiza treating cardiovascular disease from the perspective of network pharmacology. The results showed that S. miltiorrhiza treating cardiovascular disease through ten pathways as follows: improve lipid metabolism, anti-inflammation, regulate blood pressure, negatively regulates blood coagulation factor and antithrombotic, regulate cell proliferation, anti-stress injury, promoting angiogenesis, inhibited apoptosis, adjust vascular systolic and diastolic, promoting wound repair. The results of this paper provide theoretical guidance for the development of new drugs to treat cardiovascular disease and the discovery of new drugs through component compatibility.

At present, studies on traditional Chinese medicine (TCM) properties are mostly restricted to a single or two kinds of medicinal properties, but deviated from the holism of the theoretical system of TCMs. In this paper, the characteristics of pharmacological effects of different property combinations of TCMs distributing in the stomach meridian were take as the study objective. The data of properties of TCMs distributing in the stomach meridian was collected from the Pharmacopoeia of the People's Republic of China (2005). The data of pharmacological effects of TCMs distributing in the stomach meridian was collected from all of literatures recorded in Chinese Journal Full-text Database (CNKI) since 1980, Science of Chinese Materia Medica (Yan Zhenghua, People's Medical Publishing House, 2006) and Clinical Science of Chinese Materia Medica (Gao Xuemin, Zhong Gansheng, Hebei Science and Technology Publishing House, 2005). The corresponding pharmacological effects of property combinations of TCMs distributing in the stomach meridian was mined by the method of association rules. The results of the association rules were consistent with the empirical knowledge, and showed that different medicinal property combinations had respective pharmacological characteristics, including differences and similarities in pharmacological effects of different medicinal property combinations. Medicinal property combinations with identical four properties or five tastes showed similar pharmacological effects; whereas medicinal property combinations with different four properties or five tastes showed differentiated pharmacological effects. However, medicinal property combinations with different four properties or five tastes could also show similar pharmacological effects. In this study, the medicinal property theory and the pharmacological effects of TCMs were combined to reveal the main characteristics and regularity of pharmacological effects of TCMs distributing in the stomach meridian and provide a new way of thinking and method for revealing the mechanism action of TCMs distributing in the stomach meridian and discovering the pharmacological effects of TCMs distributing in the stomach meridian.

To study the relation between drug release and the drug status within curcumin-loaded microsphere, SPG (shirasu porous glass) membrane emulsification was used to prepare the curcumin-PLGA (polylactic-co-glycolic acid) microspheres with three levels of drug loading respectively, and the in vitro release was studied with high-performance liquid chromatography (HPLC). The morphology of microspheres was observed with scanning electron microscopy (SEM), and the drug status was studied with X-ray diffraction (XRD), differential scanning calorimetry (DSC) and infrared analysis (IR). The drug loading of microspheres was (5.85 ± 0.21)%, (11.71 ± 0.39)%, (15.41 ± 0.40)%, respectively. No chemical connection was found between curcumin and PLGA. According to the results of XRD, curcumin dispersed in PLGA as amorphous form within the microspheres of the lowest drug loading, while (2.12 ± 0.64)% and (5.66 ± 0.07)% curcumin crystals was detected in the other two kinds of microspheres, respectively, indicating that the drug status was different within three kinds of microspheres. In the data analysis, we found that PLGA had a limited capacity of dissolving curcumin. When the drug loading exceeded the limit, the excess curcumin would exist in the form of crystals in microspheres independently. Meanwhile, this factor contributes to the difference in drug release behavior of the three groups of microspheres.

Objective To explore the molecular basis of the characteristics of the serum auto-fluorescent spectrum in patients with ovarian cancer and the changes that might be induced by surgery. Methods Using fluorospectrophotometer and 300nm excitation light,the serum auto-fluorescent spectrum of 84 patients with ovarian cancer before and after the surgery and 30 healthy people were detected. Meanwhile, the serum tumor signs (CEA, CA199 and CA125), hemoglobin and plasma albumin level of all patients with ovarian cancer were detected. Their correlation with the fluorescence spectral characteristic parameters were analyzed. Results Compared with healthy people, the serum auto-fluorescent spectrum in patients with ovarian cancer exhibited purple-shifted position of λ2 peak and red shift in λ4 peak,had higher peak extent inλ1, λ2, λ4 and λ6 peak, and larger peak area of λ1, λ2, λ3, λ4 and λ6. Compared with those in ovarian cancer patients before surgery, the serum auto-fluorescent spectrum in these patients after operation had red shifts in λ1, λ2 and λ3 peak, lower peak extent in λ1, λ2, λ3 and λ4, and smaller peak area in λ1, λ2, λ3,λ4 and λ6 peak. In ovarian cancer patients, the serum level of CEA was positively correlated with the λ2 peak extent and the peak area of λ2 and λ3, while the serum level of CA125 was positively correlated with the peak extent of λ1-λ4 and λ6 and the peak area of λ1-λ3. The serum level of CA199 was negatively correlated with the λ2 position and positively correlated with the peak extent of λ1-λ6 and the peak area ofλ1-λ3 and λ6 in patents with ovarian cancer. Besides, the serum albumin was positively correlated with theλ2 peak position and negatively with the peak extent of λ1-λ6 and the λ1-λ3 peak area, while the level of hemoglobin was positively correlated with λ1 peak position. Conclusions The elevated serum tumor markers and lower albumin (plasma) level lead to the changes of the serum autofluorescence spectra characteristic parametersin in patients with ovarian cancer.These changes can be modestly corrected by surgery.

During professor SHAO Jing-ming's academic research and medical practice, his academic opinion of focusing spirit is gradually developed. In terms of nurturing the spirit, attention should be paid on persistence as well as everyday health maintenance and exercise to nurture the spirit of physician. In terms of clinical diagnosis and treatment, patients' psychology, employment and life status should be observed and experienced, which could bring more methods to take essential care of patients' spirit. The treatment should work with psychological counseling, advocating that based on patients' qi and spirit, various forms of treatment methods should be properly used, such as acupuncture or moxibustion or combination of acupuncture and medicine, along with simple acupoint selection and harmony medication. Before clinical treatment of acupuncture, calming the mind is critically emphasized to make a clear diagnosis. During the acupuncture, calming and focusing the mind is necessary as well as emphasizing the details, so acupuncture could be integrated with Chi Gong to create a new warming-sensation technique. In a word, the academic opinion of focusing spirit is shedding an inspiring light upon further study.
