With the surge of high-throughput sequencing technology, it is becoming popular to perform the phylogenetic study based on genomic data. A bundle of new terms is emerging, such as phylogenomics, pharmacophylogenomics and phylotranscriptomics, which are somewhat overlapping with pharmaphylogeny. Phylogenomics is the crossing of evolutionary biology and genomics, in which genome data are utilized for evolutionary reconstructions. Pharmaphylogeny, advocated by Prof. Pei-gen Xiao since 1980s, focuses on the phylogenetic relationship of medicinal plants and is thus nurtured by molecular phylogeny, chemotaxonomy and bioactivity studies. Phylogenomics can be integrated into the flow chart of drug discovery and development, and extend the field of pharmaphylogeny at the omic level, thus the concept of pharmacophylogenomics could be redefined. This review gives a brief analysis of the association and the distinguished feature of the pharmaphylogeny related terms, in the context of plant-based drug discovery and sustainable utilization of pharmaceutical resource.

Objective To evaluate the effect of health education in controlling the iodine deficiency diserders(IDD) in order to provide reference data for the further prevention and control. Methods Each village of 3 towns in Congjiang County was selected in 2007, where the health education lasting for 10 months had been implemented in the school students of 3-6 grade and the villagers. The school students of 3-6 grade and 30 housewives in the villagers were investigated for their IDD control knowledge, the salt consuming conditions as well as the sales of both rough and fine salt at a salt retail site in each village before and after the health education was implemented. Results The awareness rate of the knowledge of IDD control in the students and housewives was 91.4% (581/636) and 78.3% (282/360), respectively after intervention, which significantly increased (χ2= 532.044, 326.117, both P < 0.01) compared with the rate of 28.2% (184/652) and 11.4% (41/360) before intervention. The proportion of consuming fine salt was 91.8%(146/159) and 95.6%(86/90), significantly inereased(χ2= 236.623, 135.350, both P < 0.01) compared with 6.1%(10/163) and 7.8% (7/90) found before intervention. The selling proportion of fine salt at the salt retail site in the village was 60.0%(900/1500), significantly increased(χ2= 824.176, P < 0.01) compared with 10.0%(150/1500) before intervention. Conclusions Health education and promotion is solid foundation for effectively controlling IDD, through which the students and villagers are actively and voluntarily involved in the program and hence have formed good living and hygiene habits, thus expected effect has been obtained.

OBJECTIVETo determine the difference of post-operative mortality between ORIF (open reduction internal fixation) and hip replacement for the treatment of intertrochanteric fracture in elderly by using survival analysis.

METHODSThe clinical data of 110 patients above 60 years old who underwent surgical treatment (ORIF or hip replacement) for the intertrochanteric fracture between April 2003 and May 2013 were retrospectively analyzed. Among the patients, 83 cases were treated with ORIF (ORIF group), there were 32 males and 51 females, aged from 61.44 to 98.75 years old with an average of (78.52 ± 7.98) years old; and 27 cases were treated with hip replacement (arthroplasty group), there were 8 males and 19 females, aged from 71.82 to 96.54 years old with an average of (79.99 ± 6.11) years old. A survival analysis was performed on the clinical data by using SPSS 110 software. The survival rate of 1-year,2-year, 5-year and the mean survival time for the total patients, the mortality rate of 1-year, 2-year in each group, the survival rate of 1-year, 2-year and mean survival time and survival curve in each group were included.

RESULTSAll wounds achieved primary healing and no deaths were found in stay hospital. All patients were followed up from 1 to 125 months with an average of (46.93 ± 29.53) months. Among all 110 cases, 31 were dead and 79 survived. The survival rate of 1-year, 2-year and 5-year was (90.7 ± 2.8)%, (82.5 ± 3.9)% and (57.6 ± 6.5)%, respectively,while the ensemble mean survival time was (84.137 ± 5.902) months. The mortality rate of 1-year, 2-year in ORIF group was 7.2% and 12.0%, respectively; and in arthroplasty group, there was 14.8% and 25.9%, respectively. There was no significant difference in mortality rate of 1-year and 2-year between two groups. According to the survival analysis of the ORIF group, the survival rate of 1-year, 2-year was (92.6 ± 2.9)%, and (85.8 ± 4.3)%, respectively, and the mean survival time was (87.508 ± 6.063) months. In arthroplasty group, the survival rate of 1-year, 2-year was (85.2 ± 6.8)% and (73.9 ± 8.5)%,and the mean survival time was (67.294 ± 11.180) months. There was significant difference in mean survival time between two groups (P < 0.05).

CONCLUSIONORIF can achieve a better postoperative survival compare with hip replacement in treating intertrochanteric fracture in elderly.

OBJECTIVE To study the clinical curative effect of Qigui Yishen decoction in the treatment of patients with chronic kidney diseases of spleen and kidney deficiency.METHODS Patients with chronic kidney diseases met the diagnosis criteria were divided into two groups.Both groups were given the high quality low protein,low salt,low fat,low phosphorus diet,and also given basic treatments such as correcting water and electrolyte disorders,acidosis,anemia,lowering blood pres-sure,anticoagulation and regulating lipid.On the basis of this,the treatment group was also given Qigui Yishen decoction o-rally.Objective indexes including kidney function,serum plasminogen activator inhibitor-1(PAI-1),transforming growth fac-tor-β1(TGF-β1)and changes of TCM syndrome scores were observed after four weeks.RESULTS After the treatment,TCM syndrome scores in two groups decreased significantly compared with pre-treatment(P<0.05~0.01),and the treatment group was better than the control group(P<0.05~0.01).PAI-1,ALB/Cr,TGF-β1 and IL-6 levels in two groups decreased significantly after treatment(P<0.05~0.01),and the treatment group was better the control group(P<0.05~0.01). CONCLUSIONS Qigui Yishen decoction has definite curative effect on protecting renal function and alleviating the progress of renal fibrosis,and its therapeutic effect may be related to the improvement of blood coagulation and endothelial cell function.

Objective To explore the impact and regularity of snail population after changing of water level and to develop effective control and prediction programs. Methods A typical snail habitat closed to Changjiang county in Yueyang city, Hunan province was selected as the survey field.Data on water level and the changing trend of snail population during 2001-2009 including the average water level, maximum and minimum water levels, snail and infected snail densities,proportion of sampling frames with living and infected snails etc. were collected. The distribution of water level and snail indexes were described and a general additive model(GAM)for the relationships between these indexes were also fitted. Results Impacts of the average water level and the watered-out days in current year in the surveyed field on the snail density were statistically significant(P＜0.01), showing a quadratic curve association. The snail density remained at the lowest level when the average water level was at 25.0 m and the surveyed field watered-out days was 120. The average water level in current year and the field watered-out days in the past year showed statistically significant impacts on the infected snail density(P＜0.001), the proportion of sampling frames with infected snails(P＜0.05)and living snails(P value neared 0.05), presented a quadratic curve, a cubic curve or even a more complicated piecewise curve association. Both the infected snail density and the proportion of sampling frames with infected snails remained at the lowest level when the average water level was at 25.0 m and the watered-out days in the past year was 110, while the proportion of sampling frames with living snails kept the lowest level when the average water level was at 25.0 m and the watered-out days in the past year was 160. Conclusion The water level and the field watered-out days affected the development of snail population directly. The changing water level had an impact on snail population change, which mainly presented as nonlinear smooth function relation. Impact of the field watered out days on the infected snail density and the proportion of sampling frames with living snails and infected snails showed a hysteresis effect. The snail density was predicted to be retaining a high level when the water level was 24.0 m and the field watered-out days was 3 months. It had obvious advantages to fit the relationship of the changing water level and the snail indexes with a GAM which could get closer to the reality as well as easier to find and explain the potential associations and regulations.

OBJECTIVETo investigate the possible roles of adenosine and the cytokines TNF-alpha and IL-10 in the pathogenesis of acute bacterial prostatitis (ABP) in rats.

METHODSForty-eight male Wistar rats were randomly divided into groups A (ABP), B (ABP + theophylline intervention), C (sham) and D (blank control). ABP models were established by injecting Escherichia coli 0157 into the prostate, and those in group B were treated by intraperitoneal injection of theophylline immediately after modeling. At 4 and 14 days, the prostate tissues of the rats were collected for detection of the expressions of TNF-alpha and IL-10 by immunohistochemistry and the concentration of adenosine by high-performance liquid chromatography.

RESULTSAt 4 and 14 days, the concentrations of adenosine were significantly higher in group A ([48.38 +/- 17.27] and [26.54 +/- 11.22] microg/g) than in C ([0.45 +/- 0.25] and [0.46 +/- 0.29] microg/g) and D ([0.41 +/- 0.23] and [0.43 +/- 0.27] microg/g) (P < 0.05), and so were the expressions of TNF-alpha in A (0.23 +/- 0.08 and 0.21 +/- 0.03) than in C (0.07 +/- 0.03 and 0.07 +/- 0.01) and D (0.07 +/- 0.06 and 0.07 +/- 0.06) (P < 0.05), and those of IL-10 in A (0.13 +/- 0.03 and 0.25 +/- 0.01) than in C (0.07 +/- 0.03 and 0.07 +/- 0.03) and D (0.07 +/- 0.01 and 0.07 +/- 0.02) (P < 0.05). Compared with group A, the rats in group B showed significant increases at 4 and 14 days in the severity of inflammation, concentration of adenosine ([86.64 +/- 32.87] and [51.17 +/- 22.96] microg/g, P < 0.05) and expression of TNF-alpha (0.37 +/- 0.08 and 0.32 +/- 0.06, P < 0.05), but exhibited no remarkable difference in the expression of IL-10 (0.12 +/- 0.06 and 0.15 +/- 0.06, P > 0.05).

CONCLUSIONAdenosine may affect the progression of inflammation by regulating the expressions of the cytokines TNF-alpha and IL-10 in ABP rats through the adenosine receptor signaling pathway.
