The complete chloroplast genome of medicinal plant Asarum caudigerum Hance and its close relative A. cardiophyllum Franchet were sequenced using Illumina Hiseq technology, and assembled, annotated, and characterized by bioinformatic methods in this study. Then phylogenetic analysis of the complete chloroplast genomes of A. caudigerum, A. cardiophyllum, and twelve published species was conducted. The results indicated that the chloroplast genomes ranged from 186 215-186 985 bp in length, with a large single copy (LSC, 89 445-90 169 bp) and two inverted repeats (IRa/IRb, 48 387-48 408 bp). The overall GC content was 37.4%-37.5%. A total of 144 chloroplast genes were annotated, including 98 protein coding genes, 38 tRNA genes and 8 rRNA genes. In addition, complex genomic rearrangements were detected in the chloroplast genome of Asarum. Meanwhile, visual evaluation of the discrete type of the sequence indicated that the variation level of non-coding region was higher than that of coding region. Phylogenetic analyses suggested that A. caudigerum and A. cardiophyllum were clustered into a single clade and A. cardiophyllum, A. sieboldii var. seoulense, A. misandrum and A. maculatum were clustered into another single branch. These two clade were sister species. This study provides a scientific basis for the identification, phylogenetic relationship, molecular breeding of Asarum species.

Objective To summarize the ultrasonographic features and differential diagnosis of uterine cornual pregnancy.Methods Trans-abdominal and trans-vaginal ultrasound were performed in 93 uterine cornual pregnancy patients before surgery,ultrasonographic findings of uterine cornual pregnancy through different two approaches were analyzed and compared with surgical and pathologic findings.ResultsIn contrast with surgical and pathological diagnosis,66 cases(82.5%,66/80) of uterine cornual pregnancy were accurately diagnosed by ultrasonography before surgery,these cases were divided into gestational sac pattern (55 cases) and mixed mass pattern(11 cases); 11 cases were misdiagnosed as interstitial tubal pregnancy,2 cases were misdiagnosed as pregnancy in rudimentary horn,1 case was misdiagnosed as choriocarcinoma,misdiagnosed rate were 17.5%(14/80); uterine cornual pregnancy presented as adnexal mass in ultrasound in 13 cases,while ruptured uterine cornual mass were found in surgery,in which location and type of the masses couldn't be accurately diagnosed by ultrasound.Ultrasonographic features of uterine cornual pregnancy presented as a gestational sac located in extended cornual of uterus,surrounded by thin myometrium,and connected with endometrium.The misdiagnosed causes were: (1) Uterine cornual mass was not connected with endometrium or surrounded by thin myometrium,which were misdiagnosed as interstitial tubal pregnancy.(2) Uterine cornual pregnancy with thick lateral myometrium were misdiagnosed as pregnancy in rudimentary horn.(3)Uterine cornual pregnancy presented as cornual mass with abundant blood flow was misdiagnosed as choriocarcinoma.Conclusions Uterine cornual pregnancy can be accurately diagnosed by trans-abdominal and trans-vaginal ultrasound.Ultrasonographic features are helpful in differential diagnosis of uterine cornual pregnancy.

·AIM:To determine the effect of anterior-posterior joint surgery on choroidal thickness in patients with proliferative diabetic retinopathy (PDR). · METHODS: A retrospective, case - control study enrolled 60 eyes of 60 patients with PDR diagnosed at Qingdao Municipal Hospital. The patients, who had conditions that warranted anterior - posterior joint surgery,were divided into a clinically significant macular edema group (PDR/CSME+;31 patients,31 eyes) and a non-CSME group (PDR/CSME-;29 patients,29 eyes). Twenty-seven eyes of 27 normal patients were included in the control group. All affected eyes underwent anterior - posterior joint surgery. After surgery, the subfoveal choroidal thickness (SFCT), and the nasal choroidal thickness (NCT) and temporal choroidal thickness (TCT), which were obtained at a distance of 1500μ m from the fovea in the nasal and temporal directions, respectively, were measured in the control and PDR groups by enhanced depth imaging spectral domain optical coherence tomography (EDI-SDOCT) at 1wk,1,3, and 6mo after surgery. Changes in choroidal thickness after anterior - posterior joint surgery were compared between the groups. ·RESULTS:The SFCT,NCT,and TCT were significantly thicker at 1mo than at 1wk, 3, and 6mo after surgery in the PDR/CSME+ and PDR/CSME- groups(P<0.05). The SFCT, NCT, and TCT were significantly thinner at 6mo than at 1wk,1,and 3mo after surgery in the PDR/CSME+and PDR/CSME- groups(P<0.05). The SFCT,NCT,and TCT in the PDR/CSME+ and PDR/CSME- groups at 1wk, 1, and 3mo after surgery were significantly thicker than those in the control group (all P<0.05), but the SFCT, NCT, and TCT at 6mo after surgery showed no significant difference compared with the control group (all P>0.05). There was no significant difference in the SFCT,NCT, or TCT at 1wk, 1, 3, or 6mo between the PDR/CSME+ and PDR/CSME- groups (P>0.05). ·CONCLUSION:The choroidal thickness of PDR patients increases within 1mo after surgery, and decreased after 1mo,but is not significantly different between the control group and the PDR groups at 6mo after surgery. Whether PDR is associated with CSME has no effect on the choroidal thickness after surgery.

Objective To study the effects of adjuvant Huaier on long-term survivals after curative partial hepatectomy for primary liver cancer.Methods 175 patients with primary liver cancer who received curative partial hepatectomy from January 2002 to January 2006 were divided into two groups:the treatment group (group A,n =87) and the control group (group B,n=88).Group A was treated with Huaier (60 g per day for 6 months) after the operation while group B received no Huaier treatment.Results The overall 1-,3- and 5 year survival rates and disease-free survival rates were 91.90％,73.90％,and 56.0％ and 68.1％,48.4％ and 40.2％,respectively.The overall 1-,3-and 5-year survival rates in group A were significantly higher than group B (91.80％,79.30％,65.2％ vs 92.0％,68.3％,46.6％,P 0.038).In addition,the 1-,3-and 5-year survival rates after tumor recurrence in group A was also significantly higher than group B (78.6％,46.9％,38.2％ vs 69.0％,16.8％,12.6％,P=0.040).Multivariate analysis showed that the use of Huaier,hepatitis infection,severity of cirrhosis,vascular cancer thrombus were the most important prognostic factors for overall long-term survival (P＜0.05).Blood transfusion and histological grade were independent risk factors for disease free survival.The use of Huaier and the clinicopathological type were significantly co-related to the survival from recurrence/metastasis to death.Conclusion The use of Huaier improved disease free survival and the survival from recurrence or metastasis for patients with primary liver cancer following curative hepatectomy.

OBJECTIVETo investigate the effect of the secretory proteins of the ventral prostate on the glycoproteins in the oviductal fluid of golden hamsters.

METHODSMale golden hamsters were divided into four groups: sham operation (SH), total removal of accessory sex glands (TX), and retainment of the ventral prostate only (VP). Oviductal fluid was collected from female hamsters at 0.5, 2, 4 and 6 h after mating with the males of different operated groups with or without ventral prostate. Glycoproteins were probed with a panel of lectins and their changes in the oviductal fluid were analyzed by Western blot.

RESULTSThe 47 000, 52 000, 81 000 and 128 000 WGA-binding proteins were observed in the oviductal fluid of the 6 h TX group, the 32 000, 35 500, 47 000 and 52 000 WGA-binding glycoproteins noted in the 6 h VP group, the 47 000, 68 000, 95 000 and 128 000 pisum sativum agglutinin (PSA)-binding glycoproteins shown in the 6 h TX and VP groups, two extra 32 000 and 37 500 bands detected in the 6 h VP group, the 47 000 and 52 000 dolichos biflorus agglutinin (DBA)-binding glycoproteins present in the 6 h VP but absent in the 6 h TX group.

CONCLUSIONVentral prostate secretory proteins affect acetylglucosamine, N-acetylgalactosamine/galactose and mannose in the oviductal fluid collected 6 hours after mating. And these glycoproteins may play an important role in the development of embryos.

OBJECTIVETo investigate the binding of secretory proteins in the ventral prostate to the surface of sperm.

METHODSWe used different techniques to demonstrate the possibility of ventral prostate secretory proteins binding to sperm in golden hamsters. Polyclonal antibodies against crude secretion of the ventral prostate cultured in rabbits were used to detect the antigens in hamster epididymal, uterine and oviductal spermatozoa by indirect immunofluorescence technique. The uterine and oviductal spermatozoa were collected after mating with the males with or without ventral prostate glands. The ventral prostate secretory proteins were isolated and transblotted to the membrane, which was incubated with the biotinylated epididymal sperm membrane proteins, and then the biotinylated binding proteins were stained.

RESULTSAn immunoreaction restricted to the middle piece was observed in the sperm incubated with the ventral prostate secretion and ejaculated sperm recovered from the uteri and oviducts. The rate of the epididymal sperm bound with the ventral prostate secretory proteins was (80 +/- 5) %, and the rats of the sperm binding to the ventral prostate secretory proteins were (30.0 +/- 4.6) % from the uterus and (16.0 +/- 3.6) % from the oviduct after mating with the males with ventral prostate glands, significantly higher than after mating with those without prostate glands (P < 0.01). Five bands were identified by Western blot analysis in vitro of the ventral prostate secretory proteins incubated with biotinylated epididymal sperm membrane proteins.

CONCLUSIONThe present data indicate that ventral prostate secretory proteins bind to the middle piece of sperm in golden hamsters.

Toxoplasma gondii, an obligate intracellular protozoan parasite of the phylum Apicomplexa, can infect all warm-blooded vertebrates, including humans, livestock, and marine mammals. The aim of this study was to investigate whether superoxide dismutase (SOD) of T. gondii can be used as a new marker for genetic study or a potential vaccine candidate. The partial genome region of the SOD gene was amplified and sequenced from 10 different T. gondii isolates from different parts of the world, and all the sequences were examined by PCR-RFLP, sequence analysis, and phylogenetic reconstruction. The results showed that partial SOD gene sequences ranged from 1,702 bp to 1,712 bp and A + T contents varied from 50.1% to 51.1% among all examined isolates. Sequence alignment analysis identified total 43 variable nucleotide positions, and these results showed that 97.5% sequence similarity of SOD gene among all examined isolates. Phylogenetic analysis revealed that these SOD sequences were not an effective molecular marker for differential identification of T. gondii strains. The research demonstrated existence of low sequence variation in the SOD gene among T. gondii strains of different genotypes from different hosts and geographical regions.
