OBJECTIVETo explore the distribution characteristics of basic syndromes and its related factors in patients with chronic functional constipation (CFC).

METHODSThe complete data of 538 patients with CFC were collected and initial database was established with Epidata 3. 0. TCM syndrome typing was performed. The distribution characteristics of basic syndromes were analyzed using SPSS 17. 0 Software. The univariate and multivariate Logistic regression analyses were performed with SPSS 17. 0 Software to determine basic syndrome related factors such as age, engaged professionals, sleep quality, depression, mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation, and so on.

RESULTSThe TCM syndrome frequency of CFC patients was sequenced from high to low as qi deficiency syndrome (380 cases, 70.6%), qi stagnation syndrome (337 cases, 62.6%), blood deficiency syndrome (234 cases, 43.5%), yin deficiency syndrome (220 cases, 40.9%), yang deficiency syndrome (197 cases, 36.6%), and others(58 cases, 10. 8%) . Most patients were complicated with complex syndromes, and the most common complex syndromes were qi deficiency complicated qi stagnation syndrome (275 cases, 51.1%) and qi deficiency complicated blood deficiency syndrome (222 cases, 41.3%). Aging, work fatigue, and exercise conditions were main related factors for qi deficiency syndrome (P <0. 01, P <0. 05). Poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, defecation barriers constipation were main related factors for qi stagnation syndrome (P <0.01). Sleep quality and poor emotional (depression and anxiety tendencies) were main related factors for blood deficiency syndrome (P <0. 01, P < 0.05). Stimulating beverages were main related factor for yin deficiency syndrome (P <0.05). Engaged in mental work and slow transit constipation were main related factors for yang deficiency syndrome (P < 0. 01, P <0. 05).

CONCLUSIONSCFC is featured as complex syndromes. The most common complex syndromes were qi deficiency complicated qi stagnation syndrome and qi deficiency complicated blood deficiency syndrome. Basic syndrome related factors such as age, engaged professionals, sleep quality, poor emotional (depression and anxiety tendencies), mental stress, interpersonal relations, work fatigue, stimulating beverage, exercise conditions, Western medicine type of constipation were associated with the distribution of CFC syndromes.

OBJECTIVETo explore the effect of Bushen Tiaojing Recipe (BTR) on the quality of oocytes, reproductive hormones, and the expression of bone morphogenetic protein-15 (BMP15) of in vitro fertilization-embryo transfer (IVF-ET) patients.

METHODSSixty infertility patients who prepared for IVF-ET were assigned to two groups according to the treatment order, the treatment group [20 cases, treated with BTR + controlled ovarian hyperstimulation (COH)] and the control group (treated with COH alone, 40 cases). Age, the time limit for infertility, basal follicle-stimulating hormone (bFSH) concentration, usage days and the dosage of gonadotropins (Gn), serum levels of estradiol (E2), luteotropic hormone (LH), and progesterone (P) on the HCG injection day, the number of retrieved occytes, the fertilization rate, the number of embryos, the high quality embryo rate, and the clinical pregnancy rate were compared. Concentrations of follicle-stimulating hormone (FSH), LH, E2, testosterone (T), and P in the follicular fluid were detected via chemiluminescence microparticle immunoassay. The mRNA and protein expression of BMP-15 in mature granulosa cells was detected by real-time fluorescent PCR and Western blot.

RESULTSThirty-two patients were pregnant and the total pregnancy rate was 53.3%. Of them, 19 were pregnant and the total pregnancy rate was 47.5% in the control group, while 20 were pregnant and the total pregnancy rate was 65.0% in the treatment group. But there was no statistical difference between the two groups (P > 0.05). Compared with the control group, the Gn dosage was lower and the high quality embryo rate was higher in the treatment group, showing statistical difference (P < 0.05). There was no statistical difference in serum concentrations of E2, LH, or P on the HCG injection day, the number of retrieved oocytes, or the fertilization rate (P > 0.05). Compared with the control group, FSH concentrations in the follicular fluid were significantly lower and LH concentrations were significantly higher in the treatment group (P < 0.05). The LH concentrations in the follicular fluid were significantly higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).There was no statistical difference in E2, T, or P concentrations (P > 0.05). The mRNA and protein expression of BMP-15 in granulosa cells was higher in the treatment group than in the control group (P < 0.05). It was also higher in pregnant patients than non-pregnant patients, showing statistical difference (P < 0.05).

CONCLUSIONDuring the IVF-ET process, BTR could elevate the quality of oocytes, and increase the sensitivity of ovarian follicles to exogenous Gn, which was correlated with the mRNA and protein expression of BMP-15 in granulosa cells, and changing concentrations of FSH and LH.

The rice gall dwarf disease, caused by the Rice gall dwarf virus (RGDV) is a serious disease occurring in rice in many regions of Guangdong province. As a basis to control the disease we have studied the genomic diversity of a variety of isolates from different locations. Genome segment 8(S8), encoding a main outer capsid protein (Pns8) of RGDV five isolates (BL, CH, DQ, GZ, XY) from Guangdong province was cloned and sequenced. The results revealed that all the S8 segments of the five isolates consisted of 1 578 nucleotides and had a single open reading frame (ORF) extending for 1 301 nucleotides from nucleotide 21 which encoded a polypeptide of 426 amino acids with an estimated molecular weight of 47.4 kDa. The S8 full-length sequence and the ORF sequence shared 97.3%-98.8% and 97.3%-99.1% nucleotide sequence identities within the five Chinese isolates, and shared 94.8%-95.6% and 95.0%-96.0% identities with those of the Thailand isolate respectively. The deduced amino acid sequence of Pns8 in GZ isolate was identical to that in the Thailand isolate, while the amino acid sequence variability of Pns8 within five Chinese isolates ranged from 0.5% to 2.1%. These results indicate that the S8 segment of RGDV is highly conserved in different isolates from different locations. The S8 cDNA from the XY isolate was cloned into the plasmid vector pET-28b(+) and a fused expression protein with an apparent molecular mass of 51kDa was specifically detected in an analysis of Escherichia coli Rossetta(DE3)Ⅱcells. To our knowledge, this is the first report on analysis of the RGDV segment 8 sequence and genetic comparison of different RGDV isolates and their protein expression.

BACKGROUNDTumor involving the septum pellucidum is uncommon. Surgery as the main therapeutic procedure for this lesion is a challenge to neurosurgeons. We analyzed the clinical characteristics and pathological features of septum pellucidum tumor in 41 patients and compared the curative effects of frontal transcortical, trans-sulcal and interhemispheric transcallosal approaches.

METHODSClinical characteristics and the pathological features of septum pellucidum tumor were investigated retrospectively in 41 patients. The differences in postoperative residual rates, extents of tumors and resection of normal brain tissues after use of the three approaches in these patients were analyzed statistically.

RESULTSSeptum pellucidum tumor is more likely to attack young or middle-aged persons. The tumor mainly presents itself as a central neurocytoma or cerebral low-grade glioma in pathology and manifests as intracranial hypertension clinically. No difference was found in the extent of tumor resection but significant difference in the extent of normal brain tissue resection and in postoperative disability rate among the three approaches. The transcortical approach brought about the most serious injury to brain tissue and the highest disability rate, Whereas the frontal transcallosal approach the lightest injury and the lowest disability rate. The injury to brain tissue and the disability rate brought about by the front trans-sulcus approach were between the above two approaches.

CONCLUSIONSOperation is still regarded the major treatment for septum pellucidum tumor. Transcallosal and trans-sulcus approaches are fit with the concept of minimally invasive surgery, and transcallosal approach is the first choice for septum pellucidum tumor.

Aeroto-Niu-O16, an oxygen-tolerant bovine rumen bacterium, is capable of aerobically reducing isoflavones daidzein and genistein to dihydrodaidzein and dihydrogenistein through catalytic hydrogenation. In this study, it was found that bacterium strain Aeroto-Niu-O16 was able to cleavage the C-ring of liquiritigenin (LG), which is one of the main biologically active components of licorice roots, in the presence of atmospheric oxygen. LG was prepared by acid hydrolysis of the crude extract of licorice roots. The metabolite of LG obtained in strain Aeroto-Niu-O16 was identified as davidigenin (DG) based on the data of UV, MS, 1H and 13C NMR. The maximal concentration of LG that the strain Aeroto-Niu-O16 was able to transform effectively was 0.8 mmol x L(-1) and the average productivity of the metabolite DG was 71.7%. Furthermore, when 0.1% (m/v) of L-cysteine or sodium thiosulfate was added in the cultural medium, the average bioconversion rate of LG was increased from 71.7% to 78.3% and 77.2%, respectively. The in vitro antioxidant investigation showed that 1, 1-diphenyl-2-picrylhydrazyl (DPPH) radical-scavenging activity of DG was significantly or extremely significantly higher than that of LG at the concentrations from 0.2 mmol x L(-1) to 1.6 mmol x L(-1). We discoverd for the first time that LG can be converted to DG, which has stronger and wider biological activities, through microbial biotransformation method.

Objective To investigate the change of the basic fibroblast growth factor(bFGF) leve in human detrusor muscle(DM)in bladder outlet obstruction(BOO)due to benign prostatic hyperplasia(BPH)and its implication.Methods Fifty-four patients with BPH were divided into two groups:the obstructive DM stability and instability groups;and 15 men with bladder tumor who underwent operation in the same period were enrolled in the control group.The bFGF mRNA level in DM was measured by reverse transcription and polymerase chain reaction(RT-PCR)and the bFGF protein level was measured by immunohistochemical staining method.Results The bFGF-mRNA expression level of bladder smooth muscle cells was significantly lower in the control group than that in the obstructive DM stability and instability groups(all P＜0.05),but there was no significant difference between the obstructive DM stability and instability groups(P＞0.05). Conclusions The expression level of bFGF mRNA in bladder DM is elevated in BOO due to BPH,but there is little or no correlation between the increased expression of bFGF mRNA and detrusor muscle instability.

Objective To compare the efficacy and safety of zoledronic acid and alendronate in the treatment of postmenopausal osteoporosis and to provide a clinical basis for the safe use of zoledronic acid.Methods Two hundred and ten female patients with postmenopausal osteoporosiswomen in Xuanwu Hospital Capital Medical University from January 2013 to January 2014 were selected as research objects,they were randomly divided into zoledronic acid group(105 cases)and alendronate group(105 cases),patients in the zoledronic acid group were given intravenous infusion of zoledronic acid injection 5 mg one time a year,the alendronate group were given alendronate 70 mg one week,both group had been treated for 24 months.The bone mineral density of the lumbar spine and hip was measured by dual energy X-ray absorptiometry before and after treatment,and the VAS score of the pain status was measured.The chest and lumbar spine were examined by X-ray,and the adverse reactions were recorded.Results After treatment,the BMD of the lumbar spine and hip of the zoledronic acid group and alendronate group were(-1.56 ± 0.35)g/ cm2and(-2.21 ± 0.54)g/ cm2, (-1.91±0.32)g/ cm2 and(-2.16 ± 0.26)g/ cm2,which were higher than those before treatment.The differences were statistically significant(t=6.253,3.633,5.834,3.251,P<0.05).But the BMD of the lumbar spine and hip in the zoledronic acid group was significantly higher than that in the alendronate group,the difference was statistically significant(t=4.421,5.262,P<0.05).The VAS scores of the alendronate group and the zoledronic acid group at 12 months,24 months after treatment were(4.02±0.50)points and(3.01±0.44) points,(2.95 ± 0.36)points and(1.82 ± 0.24)points,which were significantly lower than those before the treatment,the differences were statistically significant(P<0.05).The VAS score of zoledronic acid group at 12 months,24 months after treatment were significantly lower than those of the alendronate group,the differences were statistically significant(t=3.513,3.647,P<0.05).The fever incidence of the alendronate group was 2.86%(3/105),lower than that of the zoledronic acid group(30.48%(32/105)),the difference was statistically significant(χ2=32.901,P<0.01).Conclusion Zoledronic acid injection and alendronate are effective in the treatment of PMOP,but zoledronic acid has better effect on increasing bone density,reducing the degree of bone pain,with better compliance.Although it has increased the incidence of adverse reactions,it is well tolerated.

OBJECTIVETo analyze the codon usage of chloroplast genome and the influencing factor in Eleutherococcus senticosus.

METHODCodon of 52 genes, which were selected from the chloroplast genome sequence of E. senticosus, was multivariate statistical and correspondence analyzed using CodonW and SPSS software.

RESULTGC content at the three position of codons by turns was 46.46%, 38.26%, 29.88%, whereas GC1 and GC2 had a significant correlation coefficient (P < 0.01). The correlation coefficient with GC12, and GC3 was 0.205 and was not significant correlated. There were 30 codons which relative synonymous codon usage was greater than 1 and 29 codons end with A and T. In the corresponding analysis, the first axis shows 10.35% variation. And there was significant correlation coefficient between ENC and GC3. The correlation coefficients with GC3 and ENC were -0.288 and 0.353, respectively. We defined 16 codons from 16 amino acids as the major preference codons in chloroplast genome of E. senticosus.

CONCLUSIONThe third positions for all codon are preferred to ending with A and T. The codon usage bias is formed under effect of mutation and selection, as well as other factors. But the selection will have a far greater impact than others.
