Objective To study the genetic diversity in Fujian Sanming Sarcandra Glabra from different geographical provenances;To construct genetic relationship diagram.Methods DNA in leaves was extracted by CTAB. Analysis and evaluation of DNA molecular level of 45 samples of different geographical provenances were conducted by ISSR method. POPgen32 software was used to calculate the genetic diversity and establish gene trees. NTSYS software was used to carry out cluster analysis.Results Six ISSR primers amplified 630 bands. Genetic diversity analysis showed that the average effective number of alleles of 45 varieties was 1.620 2;the average Nei's genetic diversity index was 0.364 5;the average Shannon information index was 0.543 2. Each point had different levels of genetic diversity. Nei's genetic diversity index of the maximum value was 0.497 2, and the minimum value was 0.107 8;Maximum Shannon information index was 0.690 3, and the minimum value was 0.219 2. Cluster analysis results showed that 45 varieties and 14 loci band data were the primitive matrix. 630 genetic similarity coefficients between two different species were obtained. The maximum similarity coefficient among different groups was 1.0, and the minimum was 0.516.Conclusion Different varieties of Fujian Sanming Sarcandra Glabra exist abundant genetic variation and has the molecular basis of abundant species. Using 0.610 as the threshold value can divide Sarcandra Glabra from 45 different geographical provenances into 6 groups. The genetic distance and geographical distance was not related.

ObjectiveTo compare the clinical efficacies of acupuncture, auricular point sticking, and the combination of the two methods in treating primary dysmenorrhea by using randomized controlled method, for selecting the optimal treatment in treating primary dysmenorrhea, and to explore the nursing care method for primarydysmenorrhea from the perspective of Chinese medicine. MethodNinety patients with primary dysmenorrhea were randomized into an acupuncture group of 30 cases (group A), an auricular point sticking group of 30 cases (group B), and a combined group of acupuncture plus auricular point sticking of 30 cases (group C). The patients were given treatment 7 d ahead of the menstrual period, a menstrual cycle as a treatment course, totally for 3 courses. The pain score and clinical efficacies were observed and compared among the three groups for statistical analyses.Result The pain scores were significantly changed in the three groups after intervention (P<0.05), there were significant differences in comparing the pain scores among the three groups after intervention (P<0.05), group A and C were superior to group B (P<0.05), and group C was superior to group A (P<0.05). The total effective rate was 96.7% in group A, versus 93.3% in group B and 100.0%in group C, and the rank-sum test showed thatZ=7.675,P=0.022 (P<0.05).ConclusionThe three treatment methods are all effective in treating primary dysmenorrhea, while combining acupuncture and auricular point sticking can approach the optimal effect.

Objective To investigate the autistic symptoms or autistic trait in the children with attention deficit hyperactivity disorder(ADHD) for facilitating the development of appropriate interventions.Methods Sixty-two 6-12-year-old high-functioned autism spectrum disorder (ASD),ADHD and typically developing (TD) children were assessed respectively using Chinese-version social responsiveness scale (SRS),and ADHD core symptoms were assessed in the ADHD children at the same time.Results ASD group＞ADHD group＞ TD group on the SRS total raw score and the five dimensions scores as well(P＜0.01).ASD,ADHD and TD group scored respectively 92.43±19.17,65.66±19.86 and 38.40±10.68 on the SRS total scale.The SRS total raw score of ADHD group exceeded the TD group for 2.55 standard deviant (SD) and with social communication (2.00 SD) and autistic mannerism (2.71 SD) deviating the most.22.58％ (14 out of 62) children with ADHD scored above the threshold on the SRS total raw score which was significantly higher than that in the TD group(P＜0.01).There were nonsignificant differences in the ADHD core symptoms between ADHD± children (with the SRS total raw score ≥85)and ADHD-children(with the SRS total raw score＜85) (P＞0.01).Conclusion Children with ADHD appear more ASD symptoms than the TD children and a considerable proportion of them reach the SRS diagnostic cut-off point.

OBJECTIVETo evaluate the diagnosis and surgical treatment of obstructive azoospermia.

METHODSWe analyzed the clinical data of 56 cases of obstructive azoospermia, 43 of them with ejaculatory duct obstruction (EDO), and the other 13 suspected of epididymal obstruction. The diagnostic methods included semen analyses, measurement of fructose and neutral alpha-glucosidase in the seminal plasma, transrectal ultrasonography (TRUS), and vasography when necessary. The 43 patients with EDO were treated by transurethral resection of the ejaculatory duct (TURED), and 11 of the 13 cases of suspected epididymal obstruction were confirmed by scrotal exploration and underwent either bilateral or unilateral vasoepididymostomy. The patients were followed up for 3 -51 months for postoperative semen quality and impregnation.

RESULTSOf the 43 azoospermia patients with EDO treated by TURED, 36 (83.7%) showed improved semen parameters and 11 (25.6%) achieved pregnancies. Among the 11 cases of azoospermia with confirmed epididymal obstruction treated by vasoepididymostomy, 6 (54.5%) had sperm in the semen assay and 3 (27.3%) achieved pregnancies.

CONCLUSIONSemen analyses, measurement of fructose and neutral alpha-glucosidase in the seminal plasma, TRUS and vasography are important diagnostic methods for obstructive azoospermia. TURED is effective for azoospermia with EDO, while vasoepididymostomy is preferable for the treatment of azoospermia with epididymal obstruction.

OBJECTIVETo investigate the ultrasonographic features of obstructive azoospermia and to evaluate transrectal ultrasonography in the diagnosis of the disease.

METHODSWe performed transrectal ultrasonography for 248 patients with obstructive azoospermia, observed the sonographic features of the prostate gland, seminal vesicle and ejaculatory duct.

RESULTSThe average volume of the prostate gland of the studied group was 13.2 ml. A total of 111 cases showed normal sonographic features, 39 cases bilateral seminal vesicle defect, 33 cases bilateral seminal vesicle aplasia, 23 cases unilateral seminal vesicle defect and contralateral seminal vesicle aplasia, 28 cases bilateral and 14 cases unilateral seminal vesicle dilatation. Of the 42 cases of seminal vesicle dilatation, 18 had ejaculatory duct dilatation and 17 had cysts in the midline of the prostate.

CONCLUSIONObstructive azoospermia varies in kind. Transrectal ultrasonography can reveal the details of the prostate, seminal vesicle and ejaculatory duct and help to classify obstructive azoospermia and determine the location of the lesion.

OBJECTIVETo investigate the antiviral effect of targeted antisense oligodeoxynucleotides (asODN) in HBV transgenic mice.

METHODSasODN phosphorothioated (5'-CATGCCCCAAAGCCAC-3') targeted to HBV pre-C/C region was synthesized. Gal15-PLL was used as drugs carrier which targeted asODN to mice liver. Twelve mice with positive serum HBsAg, HBV-DNA were divided into the Gal15-PLL-asODN-treated group or the control group randomly. In Gal15-PLL- asODN-treated group, each mouse was injected i.v. asODN 15mug/g weighty/day via tail vein for 12 days successively; while in the control group, each mouse received the same volume normal saline by the same way.

RESULTSIn the Gal15-PLL- asODN-treated group, serum HBsAg decreased at the 6th day (P<0.05), and decreased significantly at the 12th day vs pretreatment (P<0.01). The serum HBV DNA of 4/6 mice became negative. Immunohistochemistry test showed lowered HBsAg, HBcAg content in the liver. In contrast, the control group showed no apparent changes.

CONCLUSIONSGal15-PLL-asODN targeted to pre-C/C region could inhibit HBV replication and gene expression.

OBJECTIVETo study the safety, effectiveness and feasibility of suprapubis-assisted umbilical laparoendoscopic mini-dual-site surgery (SAU-LEMDS) in the treatment of varicocele.

METHODSThis study included 80 varicocele patients aged 24 - 44 (mean 28.5 +/- 2.6) years, 25 cases of grade I, 45 cases of grade II and 10 cases of grade III, 58 cases in the left side, 6 in the right and 16 in both sides, and all with asthenospermia. The patients were treated by SAU-LEMDS under subarachnoid anesthesia combined with general anesthesia in a supine position with a head-down-feet-up slope of 15 degrees. Two 5 mm trocars were inserted bilaterally at the umbilical edge, one with a 5 mm 30 degrees laparoscope placed in it, and another into the abdominal cavity below the pubic hairline with a 5 mm laparoendoscopic clipper placed in it. The operation procedure was similar to that of standard laparoscopic ligation of spermatic veins, with reservation of the spermatic artery and double-ligation of spermatic veins. And the procedure was repeated for the contralateral lesion in the bilateral cases. Postoperative follow-up was conducted for the incidences of orchiatrophy and testicular hydrocele and changes of seminal parameters.

RESULTSAll the operations were successful, with the mean operation time of (10 +/- 5.0) min (range 8 to 25 min) for the unilateral cases and (18 +/- 6.5) min (range 15 to 30 min) for the bilateral cases, the mean blood loss of (1.5 +/- 0.5) ml (range 1 to 2 ml), and the mean postoperative hospital stay of (2 +/- 0.5) d (range 1.5 to 3 d). The patients were followed up for 6 -24 (12 +/- 2.5) months, which showed significant improvement in sperm motility as compared with the baseline ([28.53 +/- 5.21] vs [19.62 +/- 3.56]%, P < 0.05), with 28 cases (35.0%) restored to normal. Recurrence was found in 4 cases (5.0%). Testicular hydrocele occurred in 7 cases (8.75%), but orchiatrophy in none. The scars in the umbilicus and suprapubis were invisible because of the wrinkles and pubic hair.

CONCLUSIONSAU-LEMDS is safe, effective and feasible for the treatment of varicocele. It is superior to umbilical laparoendoscopic single-site surgery (U-LESS) for its less invasiveness, simpler operation, and better cosmetic appearance.

OBJECTIVETo investigate the histological changes in the vestibular endorgans of Smad4 gene conditional knockout mice and to explore the influence of the Smad4 gene on vestibular development.

METHODSHistological changes of periphery vestibular organs in inner ear of Smad4 conditional knockout mice were investigated by frozen sections, immunofluorescence, confocal microscopy, scanning electron microscopy and transmission electron microscopy.

RESULTSThere was no Smad4 expression in the inner ear cartilage capsule of Smad4-/- mice. In Smad4+/- mice, Smad4 expression in the same cartilage capsule was positive, and it was strong positive in Smad4+/+ mice. Smad4 expression in vestibular sense epithelium, crista ampullaris and macula, was positive. And no difference was found among these three genotypes. Studying at scanning electron microscopy and transmission electron microscopy levels and anti-filament immunofluorescence showed that no pathological changes were observed in all the three genotype mice.

CONCLUSIONAlthough the Smad4 gene was knockout effectively in the auricular cartilage capsule of Smad4 conditional knockout mice,the histological changes of Smad4 conditional knockout mice in vestibulum auris internal were slightly.
