Abstract
The predominant objective of the research is to establish the anti-inflammatory and analgesic spectrum-effect relationship of Chloranthus fortunei (A. Gray) Solms-Laub (CF), to reveal the pharmacodynamic basis of the anti-inflammatory and analgesic effects of CF. The fingerprints of ten batches of CF from various origins were established by high-performance liquid chromatography (HPLC) and evaluated for similarity, hierarchical cluster analysis (HCA), and principal component analysis (PCA). The anti-inflammatory and analgesic effects of CF were evaluated with the xylene-induced ear swelling in mice and the acetic acid torsion test, while the anti-inflammatory and analgesic spectrum-effect relationship of CF was evaluated by gray relational analysis (GRA) and partial least squares regression analysis (PLSR) to effectively elucidate the anti-inflammatory and analgesic substance basis of CF. The ten batches of CF HPLC fingerprints established in this work successfully identified a total of 13 common peaks that refer to 4 components, with peak 1 being neochlorogenic acid, peak 3 being chlorogenic acid, peak 5 being cryptochlorogenic acid, and peak 10 being rosmarinic acid. The HCA results presented that the ten batches of CF samples were clustered into 3 categories, which was consistent with the PCA results. Simultaneously, the results of the spectrum-effect relationship also indicated that neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, and rosmarinic acid were the possible anti-inflammatory and analgesic substances of CF. In order to better understand the anti-inflammatory and analgesic substance basis of CF, this experiment established the anti-inflammatory and analgesic spectrum-effect relationship of CF, which can provide a scientific foundation for the quality evaluation and further research as well as the usage of CF herbs.

Abstract
Dalbergia hancai Benth. (D. hancai) is one of the most frequently utilized traditional Chinese medicine in Zhuang medicine. Simultaneously, it has been included in the "Quality Standard of Zhuang medicine in Guangxi Zhuang Autonomous Region (Vol. 2)" and possessed outstanding pharmacological effects. However, the pharmacodynamic material basis of D. hancai still remains unclear. In this study, the high-performance liquid chromatography (HPLC) method had been employed to establish the fingerprint of 10 batches of aqueous extract of D. hancai originated from different parts of China. At the same time, similarity evaluation, cluster analysis, and principal component analysis (PCA) had also been conducted to evaluate the common peaks. The acetic acid-induced writhing in mice had been employed as an analgesic model, and the carrageenan-induced toe swelling in mice was utilized as an anti-inflammatory model for pharmacodynamic experiments. The gray relational analysis (GRA) and partial least squares regression (PLSR) were applied to correlate the fingerprint and pharmacodynamic data to thoroughly examine its spectrum-effect relationship, whereby its analgesic and anti-inflammatory material basis had been comprehensively explored. The results revealed that the HPLC fingerprint of the aqueous extract of D. hancai had successfully identified 12 common peaks whereby two of which were further identified as protocatechuic acid and vitexin. Subsequently, through the analysis of GRA and PLSR, the chromatographic peaks that possess a critical correlation degree with the analgesic and anti-inflammatory effects of D. hancai had also been successfully discovered. Ultimately, the analgesic and anti-inflammatory effects of the 10 batches of D. hancai aqueous extract had been conclusively proved, and it was evidently indicated that these effects were attributable to the synergistic interactions between various components. Therefore, this study aims to serve as an effective analytical method for screening and predicting the effective substances of traditional Chinese medicine on the basis of the spectrum-effect relationship.

Abstract
OBJECTIVE To explore the association between depressive symptoms and the risks of rapid decline in renal function and chronic kidney disease (CKD) in middle-aged and elderly with normal kidney function. METHODS The residents aged 40- 75 years with eGFR≥60 mL·min-1·1.73 m-2 without proteinuria in Lanzhou region, who participated in the "REACTION" study carried out in 2011, were selected and followed up in 2014. A total of 4961 individuals with complete and qualified data from the two surveys were included in the subsequent analysis. Based on PHQ-9 questionnaire scores, the baseline population was divided into two groups with and without depressive symptoms. Cox proportional hazard analysis was used to compare the incidences of rapid renal function decline and CKD between the two groups and study the association of depressive symptoms with the risk of these renal conditions. RESULTS PHQ-9 questionnaire scores were not found to correlate with baseline SCr, ALB, UACR or eGFR levels among the participarts (P>0.05). After a mean follow-up time of 3.4±0.6 years, 33.9% of the participants with depressive symptoms at baseline experienced a rapid decline in renal function and 3.6% progressed to CKD. During the follow-up, the incidence of rapid decline in renal function and the risk of developing CKD were not found to correlate with depressive symptoms in these participants (P>0.05) regardless of the type of the depressive syndromes. CONCLUSION Depressive symptoms are not associated with the risks of rapid renal function decline or progression to CKD in middle-aged and elderly with normal kidney function.

Abstract
The present study aimed to evaluate the spectrum-effect relationships between high-performance liquid chromatography fingerprints and anti-inflammatory effects of Tetrastigma planicaule(Hook.)Gagnep. Chemical fingerprints of ten batches of Tetrastigma planicaule from various sources were obtained by HPLC. The anti-inflammatory activity was investigated by a model of ear swelling in mice caused by xylene and a model of cotton pellet granuloma. Hierarchical cluster analysis (HCA) results showed that all the samples were clustered into four categories, which was basically consistent with the principal component analysis (PCA) results. The results of the joint grey relational analysis (GRA) and partial least squares regression analysis (PLSR) showed that peaks 1, 2 and 12 were positively correlated with the anti-acute inflammatory effect (ear swelling) in mice, and peaks 3, 5, 6 and 11 were positively correlated with the anti-chronic inflammatory effect (cotton pellet granuloma) in mice. The anti-inflammatory effect of Tetrastigma planicaule is the result of the synergistic effect of multiple components, which provides a basis for further exploring the anti-inflammatory substances and quality evaluation of the herb.

Abstract
Sauropus spatulifolius Beille (S. spatulifolius) is a commonly used medicine of the Bourau and Yao nationalities. However, the composition of S. spatulifolius is complex, and simple chemical fingerprints cannot accurately evaluate the relationship between its composition and efficacy. In this study, high-performance liquid chromatography (HPLC) method was used to establish the fingerprint of the ethyl acetate extract of S. spatulifolius. Based on the evaluation of the similarity of chromatographic fingerprints of traditional Chinese medicine, combined with cluster analysis and principal component analysis (PCA), the common peaks of fingerprints were evaluated. The anti-inflammatory effect data were extracted through the dimethylbenzene-induced ear-swelling model in mice. The gray relational analysis (GRA) combined with partial least squares regression (PLSR) was used to study the spectrum-effect correlation of S. spatulifolius. As a result, the HPLC fingerprint of the ethyl acetate extract of S. spatulifolius was established, and 18 common peaks were identified. Except for S6, the other similarities are all above 0.915. The reference substance control method was used to identify two absorption peaks, namely, protocatechuic acid and caffeic acid. The cluster analysis results showed that 10 samples from different origins were grouped into four categories, which was consistent with the PCA results. Ethyl acetate extract of 10 batches of S. spatulifolius could significantly inhibit the ear swelling of mice (P < 0.01). Through GRA, the order of the contribution of each chemical component to the anti-inflammatory efficacy was obtained. The results of PLSR showed that the VIP values of peaks 3, 4, and 12 were greater than 1 and were positively correlated with anti-inflammatory activity. In this study, the HPLC fingerprint of the ethyl acetate extract of S. spatulifolius was established. Through the study of the spectrum-effect correlation, the anti-inflammatory active substance of the ethyl acetate extract of S. spatulifolius was obtained. The anti-inflammatory effect of S. spatulifolius was the result of the joint action of multiple ingredients. This research helps to quickly and accurately discover the active ingredient groups of traditional Chinese medicine and provides new ideas and methods for studying the effective substances of traditional Chinese medicine.

Abstract
BACKGROUND Sedum emarginatum Migo(S. emarginatum) has anti-tumor and anti-oxidant effects. This study aimed to screen the extractions of S. emarginatum against liver cancer in vitro and explore its anti-liver cancer mechanism. METHODS The CCK-8(Cell Counting Kit-8) method was used to detect the inhibitory effect of different extracts of S. emarginatum on the proliferation of liver cancer HepG2 cells. The morphological changes of the cells after administration were observed with microscopy, cell apoptosis was detected by flow cytometry, and the expression of Bax, Bcl-2 and Caspase-3 mRNA in the cells were detected by RT-PCR (Reverse Transcription-Polymerase Chain Reaction) to explore the mechanism of action. RESULTS CCK-8 method test results showed that among the different extracts of S. emarginatum, the ethyl acetate extract(1000 μg/ml, 2000 μg/ml, 2500 μg/ml, 3000 μg/ml) and n-butanol extract(1000 μg/ml, 2000 μg/ml, 2500 μg/ml, 3000 μg/ml) have the strongest inhibitory effect on the proliferation of HepG2 cells. In these 4 concentrations, the inhibitory effect increased as the concentration increased. The IC50 of the ethyl acetate extract on HepG2 cells was less than that of the n-butanol extract, so the ethyl acetate extract has a better proliferation inhibitory effect on HepG2 cells than the n-butanol extract, followed by the 70% ethanol extract(3000 μg/ml) and the water extract(3000 μg/ml), petroleum ether extract was the weakest. The results of microscopy showed that ethyl acetate extract caused hepatocarcinoma HepG2 cell morphology changed, cell density decreased, and suspension cells increased. Moreover, the results of flow cytometry showed that the ethyl acetate extract of S. emarginatum could induce HepG2 cell apoptosis at the concentrations of 2500μg/ml and 3000μg/ml. RT-PCR results showed that the expression of Bax mRNA was up-regulate by the middle(2500 μg/ml) and high(3000 μg/ml) dose groups of ethyl acetate extract. The expression of Caspase-3 mRNA was up-regulated by the low(2000 μg/ml), medium(2500 μg/ml) and high(3000 μg/ml) dose groups of ethyl acetate extract. The expression of Bcl-2 mRNA was down-regulated by the high(3000 μg/ml) dose group of ethyl acetate extract. CONCLUSION The ethyl acetate extract of S. emarginatum has the best effect on human liver cancer HepG2 cells. Its anti-hepatocellular mechanism may be related to affect the expression of apoptosis genes (Bax, Bcl-2 and Caspase-3mRNA) and promote the apoptosis of liver cancer cells. It provided a reference for the research and development of drugs for the treatment of liver cancer.

Abstract
OBJECTIVE To investigate the correlation of baseline serum 25(OH) D level with the risk of type 2 diabetes mellitus (T2DM) and blood glucose control in diabetic patients among the middle-aged and elderly individuals in Chengguan District of Lanzhou, Gansu Province. OBJECTIVE Residents aged 40 to 75 years in Lanzhou were selected from the "REACTION" study conducted in 2011 and had been followed up since 2014. A total of 5044 subjects with complete data from the two surveys were analyzed. Participants were divided into Q1, Q2, Q3, and Q4 subgroups based on quartiles of serum 25(OH)D level for comparison of the incidence of T2DM and blood glucose control. OBJECTIVE Baseline 25(OH)D level was not found to correlate with FPG, 2h-PG or HbA1c levels among the residents (P>0.05). The participants were followed up for a mean of 3.4±0.6 years, and compared with those in Q1 group, the participants in Q2, Q3 and Q4 groups did not show significantly lowered risk of prediabetes or diabetes regardless of glucose tolerance status. Among the patients with T2DM, the compliance rate of glycemic control after the follow-up was significantly higher than that before the follow-up (63.4% vs 60.6%), and the levels of HbA1c, FPG, and 2h-PG decreased obviously after the follow-up. But compared with Q1 group, Q2, Q3 and Q4 groups showed no significant changes in glycemic control compliance rate or levels of HbA1c, FPG and 2h-PG after the follow-up (P>0.05). OBJECTIVE There is no evidence that baseline 25(OH)D levels are associated with the risk of diabetes and blood glucose control in patients with T2DM.

Abstract
Seeking to optimize a novel method of isolating rare fetal erythroid cells in cultures from maternal blood, we have explored the effects of serum supplement on fetal and adult erythropoiesis. We used flow cytometry and sorting after labelling with antibodies to fetal haemoglobin (HbF) and adult haemoglobin (HbA). In adult blood-derived cultures, most nucleated red cells accumulated either only adult haemoglobin (F-A+) or a combination of fetal and adult haemoglobin (F+A+). Only a few were F+A-. Serum affected the proportions of adult cells expressing fetal haemoglobin (both F+A- and F+A+), which were minimized, but not eliminated altogether, with the use of charcoal-treated sera at low concentrations. In contrast, the expansion of fetal red cells, which made only fetal haemoglobin (F+A-) during at least one week of culture, was strongly increased with the use of charcoal treated sera, due to the removal of a charcoal-absorbable inhibitor. In co-cultures of fetal and adult erythroid cells, fetal cells could be enriched in the order of 200-fold by flow sorting with the F+A- criterion. However, since adult F+A- cells could not be suppressed completely, the purity of sorted fetal cells still depended on the relative numbers of fetal and maternal erythroid clonogenic cells in the blood sample. Thus, we demonstrate a method by which fetal nucleated red cells potentially present in maternal blood cultures can be identified and isolated from the vast majority of maternal erythroid cells, based on their correlated contents of fetal and adult haemoglobin.

Abstract
Fetal cells in maternal peripheral blood are a source of fetal DNA for prenatal genetic diagnosis, but their numbers are so small and variable that a reliable isolation procedure has yet to be demonstrated. The problem of scarcity may be overcome by amplification of fetal progenitor cells in cultures from maternal blood samples. One challenge is to identify post-culture fetal cells and colonies. We have found that the progeny of fetal and adult erythroid progenitors developed differential haemoglobin profiles in co-culture. Fetus-derived cells initially made only fetal haemoglobin (HbF) and began to express adult haemoglobin (HbA) only after intracellular HbF had reached maximum levels, which occurred after c 7 d in culture. By this time the large majority of adult-derived erythroid cells contained already high levels of HbA alone or combined with HbE Using the HbF+ HbA- criterion, we were able to flow-sort fetal cells with up to nearly 50% purity from some post-termination blood cultures, and with >90% purity in cultures from maternal blood spiked with 1% blood from the fetus. Fetal cell purity depended on culture time and serum supplement. After 7-10 d, purity was higher in low concentrations of human cord serum (1-3%) than in the standard 30% fetal calf serum. This was reversed at later times. Thus, if fetal clonogenic erythroid cells were present in maternal blood. their progeny could be isolated from most adult erythoid cells based on haemoglobin profiles. Cultures using CD34+ cells could be performed complementary to other methods targeting more mature fetal cells in the same maternal blood samples, thus increasing the overall chances of finding fetal cells and potentially providing clonal isolation of such cells.

Abstract
6,666 children under 3 years of age were selected from 231 villages in 25 townships of the Sichuan Province using a stratified random sampling design. The subjects consisted of 3,356 boys (50.3%) and 3,310 girls (49.7%); 2,510 from plain areas (37.8%),1,857 from hill areas (27.9%), and 2,299 from mountain areas (34.4%). All the children in this study had four anthropometric variables measured: body weight, length, head circumference (HC), upper-arm circumference (UAC). Three anthropometric indicators were used to measure the prevalence of malnutrition: weight-for-age (underweight), length-for-age (stunting) and weight-for-length (wasting). The prevalence of malnutrition and Z scores were calculated for male and female, respectively, by age to compare the Chinese rural children with the Chinese standard (1985) and NCHS Standard. The prevalence of moderate plus severe underweight, stunting and wasting were 20.8%,40.7% and 1.78% in boys and 19.5%, 38.3% and 2.26% in girls. The prevalence of malnutrition also varied with age. The group with the highest prevalence of malnutrition was in the first year of life, with weaning time proving to be a critical period influencing child growth and development. Z score indicated that the growth and development of Chinese rural children was behind the Chinese Urban and NCHS populations, especially after 6 months of age. Furthermore, the mean head circumference and upper arm circumference was lower in mildly malnourished children in each age gr 1000 oup than in normal children, and much lower still in moderately and severely malnourished children. The influences of malnutrition were also manifested on bone and muscle development.

Abstract
Fetal nucleated erythrocytes (FNRBC) flow sorted from maternal peripheral blood, using monoclonal antibodies (mAb) that bind fetal cell surface antigens, are a noninvasive source of fetal DNA for prenatal diagnosis. These mAbs, however, also bind antigens shared by maternal cells. In sorted populations, this results in maternal cell contamination and low fetal cell purities, which complicates genetic analysis by fluorescence in situ hybridization (FISH) and polymerase chain reaction (PCR). Fetal hemoglobin, (alpha 2 gamma 2), has been proposed as a useful fetal marker. To improve fetal cell enrichment from maternal blood, we developed an intracellular staining protocol that combines anti-gamma mAb with Hoechst 33342 to identify and flow sort FNRBC. Artificial mixtures of male umbilical cord cells (as a source of fetal hemoglobin) and female adult, non-pregnant peripheral blood mononuclear cells were stained and flow sorted using this protocol. FISH analysis was performed using chromosome X and Y specific probes. Fetal cell purities were calculated by microscope confirmation of anti-gamma staining and counting the number of X and Y signals present after FISH. Results from microscope analyses showed a fetal cell yield of 39-100% and fetal cell purities of 59-73%. These purities are significantly higher than the .001-4.8% previously reported by us in maternal samples using cell surface staining protocols. FISH results demonstrated that 83-100% (mean = 98%) of anti-gamma positive cells were male, whereas 82-100% (mean = 92.5%) of anti-gamma negative cells were female. These results confirmed that the anti-gamma mAb is highly fetal specific. When applied to maternal blood samples, this protocol should lead to increased sensitivity for prenatal diagnosis.

Abstract
Monoclonal antibody to fetal haemoglobin (alpha 2 gamma 2) has been proposed as a fetal-specific reagent. We developed an intracellular staining protocol that combines fluorescein isothiocyanate or phycoerythrin conjugated anti-gamma with the DNA binding dye Hoechst 33342 to identify and flow sort fetal erythroblasts from maternal blood. Our preliminary observations on anti-gamma-positive cells sorted from four different pregnant women are described here, using fluorescence in situ hybridization (FISH) with chromosome-specific probes to identify fetal cells. Our data demonstrate that far fewer candidate fetal cells are sorted with this protocol than by current cell surface staining methods that employ the monoclonal antibody CD71. This results in increased fetal cell sorting purities. With this protocol, standard FISH techniques require modification due to the rigorous fixation with 4 per cent paraformaldehyde. Our initial data indicate the promise of this approach.

Abstract
Irradiation with UVA light of the anti-inflammatory drug diclofenac [2-(2,6-dichloroanilino)phenylacetic acid] in aqueous buffer or methanol solution leads to sequential loss of both chlorine substituents and ring closure to carbazole-1-acetic acid as the major product. Minor products result from substitution by the solvent. The photosensitizing properties of diclofenac and its major photoproduct were tested with singlet oxygen substrates and in the free radical polymerization of acrylamide. Although the major carbazole product is a weakly phototoxic agent, able to generate singlet oxygen more efficiently than diclofenac, the free radical photodechlorination process is postulated as the probable initiation step of in vivo photosensitivity responses.
