Miscanthus sinensis Anderss is a perennial C4-grass. It is a promising bioenergy plant, which has been proposed as general feedstock for biomass and lignocellulosic biofuel production. In this study, the flower and leaf buds transcriptomes of Miscanthus sinensis Anderss were sequenced by the platform of Illumina HiSeq 2000. In total 98 326 Unigenes were generated by de novo assembly with an average length of 822 bp and N50 of 1 023 bp. Based on the NR, NT, Swiss-Prot, KEGG, GO and COG databases (Evalue < le-5), 74 134 (75.40%) Unigenes were annotated. A total of 45 507 Unigenes were mapped into different GO terms. In KEGG pathways identification, 36 710 sequences were assigned to 128 KEGG pathways. Sorghum bicolor (37 731, 60.86%), Zea mays (16 258, 26.22%), and Oryza sativa (3 065, 4.94%) showed high similarity to Miscanthus sinensis Anderss. And 24 photosynthesis-related enzyme genes were identified. The result provides a foundation for further characterizing the functional genes in Miscanthus sinensis Anderss.

Objective To study the effect of early enteral nutrition (EEN) with ω-3 polyunsaturated fatty acid on nutritional status and body immunity of postoperative patients with colorectal cancer.Methods Forty patients with colorectal cancer were randomly divided into EEN group and parenteral nutrition (PN) group by systematic sampling method with 20 cases of each.The patients in EEN group were given complete enteral nutrition with ω-3 polyunsaturated fatty acid 1-7 d after operation,while the patients in PN group only were given nutrient by regular PN.Nutritional status,body immunity before operation and 1-7 d after operation,and intestinal function recovery time,untoward reaction were determined.Results The postoperative anus first exhaust time and defecate time of patients in EEN group were significantly shorter than those in PN group [(48.0±5.6) hvs.(51.0±6.7) h,(53.0±4.8) h vs.(72.0±3.6) h,P＜0.05].Serum albumin and prealbumin 1 d after operation in 2 groups were significantly lower than before operation (P ＜0.05),but 7 d after operation were significantly higher than 1 d after operation (P ＜0.05).Serum albumin and prealbumin 7 d after operation in EEN group were significantly higher than PN group(P ＜ 0.05).IgG,IgA,IgM,CD3,CD4,CD8,CD4/CD8 1 d after operation in 2 groups were significantly lower than before operation (P ＜ 0.05).IgG,IgA,CD4,CD4/CD8 7 d after operation in EEN group were significantly higher than PN group (P＜ 0.05).Conclusions Compared with the PN,EEN with ω-3 polyunsaturated fatty acid can remarkably improve nutritional status and body immunity in postoperative patients with colorectal cancer.It can accelerate the recovery of intestine function and worthy of recommending.

OBJECTIVETo evaluate the role of undermining orbicularis oculi muscle from Orbital rim for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.

METHODS56 cases of lower eye baggy deformity with tear trough deformity and palabromalar groove were treated with the procedure of stripping eye orbicularis oculi muscle from orbital rim by a transcutaneous approach in lower blepharoplasty. The orbital septum was opened along the arcus marginalis for releasing the orbital fat. Some orbital fat was removed if necessary. Then the inferior edge of the orbital septum fat was reset over the orbital rim so as to smooth the infraorbital groove.

RESULTS56 patients were available for 6 to 18 month's follow-up. 54 patients were quite satisfied with the cosmetic result. One developed lower eyelid retraction and another one showed asymmetrical subcutaneous local uneven after 1 month's. They were all corrected by the second operation after 3 months.

CONCLUSIONSStripping orbicularis oculi muscle from orbital rim plays an important role for the correction of tear trough deformity and palabromalar groove in lower blepharoplasty.

OBJECTIVETo observe the effects of cross electro-nape-acupuncture on reflex remodeling of airway protective reflex cough in patients with tracheotomy after cerebral hemorrhage.

METHODSWith the method of completely random design, according to treatment order, 60 patients who received tracheotomy after cerebral hemorrhage accompanied with cough reflex difficulty were randomly divided into a cross electro-nape-acupuncture group and an acupuncture group, 30 cases in each group. Both groups were treated with basic treatment, including anti-inflammation, eliminating phlegm, improving cerebral metabolism and so on. The acupuncture group was treated with acupuncture at Yifeng (TE 17), Fengchi (GB 20), Lianquan (CV 23), Baihui (GV 20), Touwei (ST 8), Dicang (ST 4) through Jiache (ST 6), Hegu (LI 4), Quchi (LI 11), and motor area on the affected side, and the needles were retained for 30 min. Based on the treatment of acupuncture group, the cross electro-nape-acupuncture group was additionally treated with cross electro-nape-acupuncture (continuous wave) for 30 min per treatment. The treatment was both given twice a day from Monday to Friday and once a day on Saturday and Sun day for 4 weeks. Tracheostomy cough reflex grading score (TCRGS) and clinical pulmonary infection score (CPIS) were observed before and after treatment in the two groups, and the clinical efficacy of two groups was evaluated.

RESULTSCompared before the treatment, TCRGS and CPIS were both reduced in two groups (both P < 0.01); after treatment, there were significant differences of TCRGS and CPIS between two groups (both P < 0.01), indicating cross electro-nape-acupuncture group was superior to acupuncture group. Regarding the effects of cough reflex remodeling, the cured and markedly effective rate was 96.7% (29/30) in the cross electro-nape-acupuncture group, which was significantly different from 55.2% (16/29) in the acupuncture group (P < 0.01).

CONCLUSIONCross electro-nape-acupuncture could effectively improve the remodeling of cough reflex and promote the recovery of lung infection in patients with tracheotomy after cerebral hemorrhage, leading to an increased quality of life.

OBJECTIVETo investigate the role of single nucleotide polymorphisms of the gene of diacylglycerol kinase κ (DGKK) in hypospadias in Chinese children.

METHODSWe performed direct sequencing on 2 hypospadias-related candidate single nucleotide polymorphisms of the DGKK gene (rs1934179 and rs7063116, never previously reported in the Chinese population) from 300 children with sporadic hypospadias and 200 healthy controls, and compared the results between the two groups.

RESULTSThe mutation frequencies of rs1934179 and rs7063116 were 5.0% (15/300) and 5.67% (17/300) respectively in the hypospadias patients, significantly higher than 1.5% (3/200) and 2.0% (4/200) in the normal controls (P <0.05). The mutation frequencies of rs1934179 and rs7063116 in the cases of distal and middle hypospadias were also remarkably higher (6.5%, [13/200] and 7.5% [15/200], P <0.05), but those in the proximal cases (both 2.0% [2/100]) showed no statistically significant difference from the control (P >0.05).

CONCLUSIONThe polymorphisms of the DGKK gene may be associated with hypospadias, particularly distal and middle hypospadias, in Chinese children.

OBJECTIVETo explore the characteristics of B cell-activating factor (BAFF) secreted by peripheral blood monocyte-derived dendritic cell (MoDC) in chronic idiopathic thrombocytopenic purpura (cITP) and the function of MoDC on B cell proliferation.

METHODSTen cITP patients were studied dynamically before and after treatment. The BAFF levels in serum and the supernatant of LPS stimulated MoDC were tested with ELISA. The BAFF gene expression in LPS stimulated MoDC was tested with RQ-PCR, the B cell proliferation co-cultured with the supernatant of LPS stimulated MoDC for 5 days was tested with flow cytometry for CFSE and (3)H thymidine incorporation.

RESULTSThe BAFF level in serum (serum BAFF) \[(2461 ± 483) ng/L\], and supernatant of LPS stimulated MoDC (supernatant BAFF) \[(1113 ± 113) ng/L\] and BAFF mRNA in LPS stimulated MoDC (BAFF mRNA) (1.70 ± 0.23) before treatment were higher than that after treatment \[(621 ± 53) ng/L, (490 ± 49) ng/L and 0.37 ± 0.12\] and normal group \[(742 ± 77) ng/L, (582 ± 63) ng/L and 0.52 ± 0.08\]. There was a positive correlation among serum BAFF, supernatant BAFF and BAFF mRNA, and a negative correlation among serum BAFF, supernatant BAFF and BAFF mRNA and blood platelet count (BPC) in all ITP patients. The supernatant of LPS-stimulated MoDC from untreated patients enhanced B cell proliferation as compared with the supernatant of LPS-stimulated MoDC from treated patients and normal group.

CONCLUSIONBAFF might contribute to disease development in cITP. MoDC may directly increase B cell proliferation by secreting BAFF without T cell help, playing an important role in the antibody production in cITP.

Objective To explore the clinical value of second polar body (Pb2) exclusion monitoring by timelapse in predicting the fertilization and embryo development efficiency for intracytoplasmic sperm injection ( ICSI). Methods A retrospective research was performed on 278 patients treated with ICSI, the clinical data and Time-lapse monitoring embryo culture data were collected and analyzed, to explore the exclusion of Pb2 after ICSI and the relationship between the specific exclusion time and the outcome of fertilization and embryo development. Results The average time of Pb2 exclusion after ICSI was ( 3. 03 ± 1. 21) hours; The fertilization rate, 2 pronucleus(PN) fertilization rate and 5 days ( D5) blastocyst formation rate in the Pb2 exclusion group were significantly higher than those in the without Pb2 exclusion group (99.95% vs f. 75%, P < 0 . 001; 97.18% vs 0.66%, P< 0.001; 60.50% vs 16.67%, P < 0 . 0 5 ) ; The 2PN fertilization rate in Pb2 exclusion time >3-4 hours group was significantly higher than that in 0-2 hours group and >5 hours group (98.80% vs 9 3 . 8 1 % , P<0. 05; 98.80% vs 95.40%, P<0. 0 5 ) ; The exclusion time of Pb2 was significantly correlated with the average number of blastomeres in D3 embryos (P<0. OOf). The D5 blastocyst formation rate of 3-4 hours group was significantly lower than that of > 2-3 hours group ( 56. 23% vs 67. 23%, P < 0. 05 ) , > 4-5 hours group was significantly lower than 0-2 hours group and >2-3 hours group ( 46. 6f % vs 62. 30% , P<0. 05; 46. 6f % vs 67. 23% , P< 0. 05) , and D5 blastocyst formation rate of >5 hours group was 7. f 4 % , which were significantly lower than that of the other four groups (P<0. 05). The fonnation rate of D5 high-quality blastocysts in 3-4 hours group was significantly lower than 0-2 hours group and > 2-3 hours group ( 9. 92% vs 16. 39% , P<0. 05; 9. 92% vs 20. 72% , P<0. 05) , and D5 highquality blastocysts formation rate in > 4-5 hours group was significantly lower than that in > 2-3 hours group (11. 02% vs 20.72%, P<0. 05). Conclusion Monitoring Pb2 exclusion by Time-lapse can accurately predict fertilization outcome. The time of Pb2 exclusion is significantly correlated with embiyo development potential. It is a valuable morphological index to predict fertilization and embiyo development outcome in ICSI.

OBJECTIVETo investigate the role of the MAMLD1 gene mutation in the pathogenesis of hypospadias in the Chinese population.

METHODSWe collected peripheral venous blood from 150 Chinese children with hypospadias (the case group) and another 120 normal healthy ones (the control group), aged 0.5 to 6 years. We obtained their DNA samples and performed DNA sequencing on the single-nucleotide polymorphisms of MAMLD1, followed by comparative analysis.

RESULTSA known missense mutation polymorphism p. N589S was identified in 12 (8.0%) of the hypospadias patients and 4 (3.0%) of the normal controls, and a novel missense mutation polymorphism p. N567S was identified in 4 (2.7%) of the patients and 3 (2.5%) of the controls, neither with statistically significant differences between the two groups (P > 0.05).

CONCLUSIONThe results re-emphasized the importance of replication in genetic association approaches, and might reveal a real difference in susceptibility genes among different populations. The single-nucleotide polymorphisms of MAMLD1 bear no obvious correlation with hypospadias, and MAMLD1 is not a candidate gene in its pathogenesis in the Chinese population.
