Based on variation of Pinus massoniana families, heritablility and correlation analysis, the contents of shikimic acid and procyanidine (heritability 0.90, 0.70), dry weight of single branch (heritability 0.60) and and leaf length (heritability 0.46) were screened out as quality, yield and harvest cost traits of Folium Pini, respectively. For the different medicinal application of Folium Pini, varied methods were chosen to estimate weight and construct index equation. Weight adjustment based.on equal emphasis were used as economic weight determining method to select the best families, and the index (accuracy 0. 936 4 and heritability 0. 881 6) obtained was a little better than that obtained by equal emphasis, and much better than that by restricted index. The superior families selected with adjustment weight and equal emphasis were No. 46, 43 and 28. Partial regression were used as economic weight determining method to select the best families,and the index obtained had the highest accuracy (0.941 5) , index heritability (0. 889 9) and the genetic gain of shikimic acid content. The superior families selected with this method were No. 46, 27 and 47. No. 46 was the best families with maximal economic benefit. Our study indicated that suitable method for estimate weight and construct index equation can be applied for better accuracy of superior families selection of P. massoniana.

Objective:To observe the clinical efficacy and safety of Sofre injection combined with isosorbide mononitrate in the treatment of refractory heart failure. Methods:Totally 66 cases of patients with refractory heart failure in our hospital were randomly di-vided into the observation group and the control group with 33 cases in each. Each patient received the conventional treatment. On the basis of routine treatment, the control group was treated with isosorbide mononitrate injection (25mg,qd,ivd). On the basis of control group, the observation group was treated with Sofre injection (10ml, qd, ivd). The treatment course was 14 days. Before and after the treatment, the improvement degree clinical symptoms, left ventricular ejection fraction ( LVEF) , left ventricular end diastolic diameter (LVEDD), cardiac index (CI), stroke volume (SV) and 6-min walking distance (6MWD) were observed, and the rate of heart fail-ure hospitalization, heart failure mortality and 6MWT changes were followed up for 6 months in the two groups. The adverse drug reac-tions ( ADR) in both groups during the treatment were recorded as well. Results:After the 2-week treatment, the effective rate and the total effective rate of the observation group were significantly higher than those of the control group (P<0. 05); LVEF, CI, SV and 6MWD of the two groups after the treatment were significantly higher than those before the treatment, and LVEDD significantly de-creased (P<0. 05), and the improvement of the observation group was more obvious than that of the control group (P<0. 05). After the 6-month follow-up, 6MWD was significantly longer in the observation group than that in the control group (P<0. 05), while there were no statistically significant differences in the hospitalization rate and the mortality rate between the groups (P>0. 05). There were no adverse reactions in both groups during the whole treatment. Conclusion:Sofre injection combined with isosorbide mononitrate can significantly improve cardiac function in the patients with refractory heart failure with improved clinical efficacy and good safety.

Genetic studies are traditionally based on single-gene analysis. The use of these analyses can pose tremendous challenges for elucidating complicated genetic interplays involved in complex human diseases. Modern pathway-based analysis provides a technique, which allows a comprehen-sive understanding of the molecular mechanisms underlying complex diseases. Extensive studies uti-lizing the methods and applications for pathway-based analysis have significantly advanced our capacity to explore large-scale omics data, which has rapidly accumulated in biomedical fields. This article is a comprehensive review of the pathway-based analysis methods––the powerful methods with the potential to uncover the biological depths of the complex diseases. The general concepts and procedures for the pathway-based analysis methods are introduced and then, a comprehensive review of the major approaches for this analysis is presented. In addition, a list of available path-way-based analysis software and databases is provided. Finally, future directions and challenges for the methodological development and applications of pathway-based analysis techniques are dis-cussed. This review will provide a useful guide to dissect complex diseases.

OBJECTIVETo establish a nasopharyngeal carcinoma (NPC) cell line CNE1-pLVTHM/BART7 with stable ebv-miR-BART7 overexpression.

METHODSThe recombinant lentivirus pLVTHM/BART7 expression plasmid was packaged into mature lentivirus by 293FT cells and used to infect CNE1 cells. Flow cytometry was employed for sorting the GFP(+) cells. The efficiency of ebv-miR-BART7 overexpression was determined using qRT-PCR.

RESULTSThe recombinant lentivirus plasmid pLVTHM/BART7 was successfully constructed and verified by PCR and sequencing. The expression of ebv-miR-BART7 in CNE1 cells infected with the lentivirus pLVTHM/BART7 was significantly increased as compared with the negative control and the blank control cells.

CONCLUSIONThe recombinant lentivirus vector pLVTHM/BART7 results in high and stable expression of ebv-miR-BART7 in infected CNE1 cells, which provides a useful cell model for further studies of the role of ebv-miR-BART7 in nasopharyngeal carcinoma.

BACKGROUNDSteroid 11beta-hydroxylase deficiency (11beta-OHD), an autosomal recessive inherited disease, accounts for 5% - 8% of congenital adrenal hyperplasia. It was scarcely reported in China. This article reports two Chinese girls with 11beta-OHD.

METHODSThe two patients were sisters and presented with hypertrichosis, skin pigmentation, laryngeal prominence and virilization of external genitalia. The patients were followed up for their clinical symptoms and signs, hormone profile, and adrenal image. The genomic deoxyribonucleic acids of the patients and their parents were isolated. 11beta-hydroxylase gene (CYP11B1) was amplified by polymerase chain reaction and directly sequenced.

RESULTSHormone tests showed that serum cortisol was in the low limit of normal range, whereas the concentrations of adrenocorticotropic hormone, testosterone and progesterone were much higher than those of normal adult females. There were obvious adrenal hyperplasia and advance of bone age. After 11 months of treatment with dexamethasone, the skin pigment became regressed; the breast, uterus and ovary gradually developed and normal menstrual cycle started while the manifestations of virilization did not change. A single point mutation of CYP11B1 (R454C, GGC --> TGC) in all the members of this family was detected. The sisters were homozygous and their parents were heterozygous.

CONCLUSIONSThe clinical manifestation of 11beta-OHD is complicated. The manifestation of virilization could not regress after treatment with dexamethasone. The novel missense mutation of CYP11B1 (R454C, GGC --> TGC) is the pathogenesis of 11beta-OHD at least in some Chinese patients.

METHODSThirty two patients with OSAHS, age ranged from 27 to 54, mean value (x +/- s) 39.1 +/- 7.8, male, body mass index (BMI) ranged from 22.9 to 36. 7 kg/m2, mean value (29.0 +/- 3.6) kg/m2, preoperative apnea and hypopnea index (AHI) was 11.7/h to 113.7/h, mean value (61.8 +/- 21.9)/h, the lowest blood oxygen saturation was 0.10 to 0.85, mean value 0.64 +/- 0. 13. With preoperative endoscopic technique, bony nasopharynx cavity narrowing were present, 14 patients had concomitant tonge-base obstruction. Cephalometric result, SNA ranged from 72.9 degrees to 87.0 degrees, mean value (80.7 +/- 4.1) degrees; SNB 69.50 to 85.0 degrees, mean value (76.8 +/- 4.5) degrees; PAS 0.5 cm to 2.1 cm, mean value (1.2 +/- 0.5) cm; MP-H: ranged from 1.2 cm to 3.5 cm, mean value (2.2 +/- 0.7) cm; PNS ranged from 2.4 cm to 3.5 cm, mean value (2.8 +/- 0.4) cm. All the patients had H-UPPP and concomitant transpalatal advancement pharyngoplasty. Fourteen patients with tonge-base obstruction had chin advancement. Results Six months after the operations, the patients were evaluated the response to the operations using Epworth sleep scale, OSAHS filtration questionnaire scale and polysomnography (PSG). There were 27 patients with the decrease percent of AHI reaching or more than 25% and 22 patients with the decrease percent of AHI reaching or more than 50% including 8 patients with AHI less than 5. The other 5 patients were ineffective. After operation, the Epworth sleep scale decreased from (9.2 +/- 4.5) to (4.7 +/- 2. 8) and OSAHS filtration questionnaire scale decreased form (56.0 +/- 15.3) to (17.5 +/- 11.5). Both of the differences were obvious (P < 0.01).

CONCLUSIONSCombination of transpalatal advancement pharyngoplasty and H-UPPP can improve the efficacity and in some patients with pure retropalatal airway narrowing, the cure rate can be improved.

ObjectiveTo investigate the potential pharmacological mechanism of Xinmaikang tablets in the treatment of atherosclerosis cardiovascular disease by using network pharmacology and cell experimental validation. MethodThe components of Xinmaikang tablets were searched by BATMAN-TCM database and the active ingredients and potential targets were screened. The atherosclerosis related disease targets were searched in GeneCards and online mendelian inheritance in man（OMIM） disease databases. The therapeutic targets were obtained by mapping the intersection of the tablets and disease targets. Therapeutic targets were uploaded to STRING database to construct protein-protein interaction（PPI） network. Cytoscape software was used to create a "drug-active component-therapeutic target" network map， and a network topology algorithm was used to screen key action targets. David software was used for gene ontology（GO） and Kyoto encyclopedia of genes and genomes（KEGG） function enrichment analysis. The key targets of drug therapy were validated by in vitro cell assay. ResultA total of 19 active ingredients， 132 potential targets and 4703 atherosclerotic disease-related target genes of Xinmaikang tablets were retrieved and screened， and 84 intersection targets were obtained. 3 key therapeutic targets of Xinmaikang tablets in the treatment of atherosclerotic diseases were screened， including Calmodulin 1（CALM1）， voltage-dependent L-type calcium channel subunit alpha-1C（CACNA1C） and Phosphatidylinositol 4，5-bisphosphate 3-kinase catalytic subunit alpha isoform（PIK3CA）. A total of 313 biological processes， 89 molecular functions and 53 cell components were obtained by GO enrichment. A total of 40 pathways were obtained from KEGG functional enrichment， including purine metabolism， renin secretion， CGMP/PKG signaling pathway and so on. In vitro cell experiment results verified that Xinmaikang tablets can up-regulate the expression of CALM1 and CACNA1C， down-regulate the expression of PIK3CA， so as to inhibit the activity of inflammatory response， and play a therapeutic role in atherosclerotic diseases. ConclusionXinmaikang tablets may treat atherosclerosis cardiovascular disease through betulin， methyleugenol and other compounds， through purine metabolism， renin secretion， cGMP/PKG signaling pathway and other pathways， which acts on CALM1， CACNA1C， PIK3CA and other targets.
