Abstract
Traumatic carotid-cavernous fistula (TCCF) with perimedullary venous drainage and delayed myelopathy is a relatively rare clinical lesion. Endovascular embolization using embolic agents is the preferred treatment for patients with a poor collateral circulation. The present study describes the case of a 45-year-old male with TCCF, who presented with progressive cervical myelopathy for 1 month. A previous history of the patient included an anterior skull base fracture induced by a traffic accident 2 years prior. Cervical spinal magnetic resonance imaging (MRI) revealed dilated perimedullary veins and cervical spinal cord edema. Cerebral digital subtraction angiography revealed a direct CCF with perimedullary venous drainage. The patient received endovascular treatment with coils and an Onyx liquid embolic system to occlude the fistula, and his symptoms were relieved when he was discharged 3 weeks later. The patient then felt normal and a cervical spinal MRI revealed the disappearance of the perimedullary veins dilation and spinal cord edema at the 6-month follow-up. To the best of our knowledge, only three cases of CCFs with perimedullary venous drainage presenting with myelopathy have been previously reported. The present study also discussed the possible pathological mechanisms for this rare presentation. Moreover, it is suggested that the possibility of CCFs as a cause of cervical myelopathy needs to be taken into consideration.

Abstract
Objective: To investigate the intervention effect of SB431542, which inhibits the TGF-β/Smad3 signaling pathway, on silicotic fibrosis in rats. Methods: A total of 40 specific pathogen-free Sprague-Dawley rats were divided into normal saline control group, model group, SB431542 inhibitor group, and SB431542 inhibitor control group using a random number table, with 10 rats in each group. All rats except those in the normal saline control group were given non-exposed single intratracheal instillation of free silicon dioxide dust suspension 1 mL (50 mg/mL) ; the rats in the SB431542 inhibitor group were given intraperitoneal injection of SB431542 (5 mg/kg) on days 7 and 30 after dust exposure, those in the SB431542 inhibitor control group were given intraperitoneal injection of SB431542 cosolvent (5 mg/kg) on days 7 and 30 after dust exposure, and those in the normal saline control group were given intratracheal instillation of an equal volume of normal saline (5 mg/kg). On day 60 after dust exposure, the paraffin-embedded section of the right upper lobe of lung was collected for HE staining; the left upper lobe of lung was collected to measure the mRNA levels of fibronectin (FN) , collagen type I (COL-I) , and collagen type III (COL-III) by quantitative real-time PCR; the right inferior lobe of lung was collected to measure the protein levels of FN, COL-I, COL-III, phosphorylated Smad3 (p-Smad3) , and Smad3. Results: Compared with the normal saline control group, the model group had nodules with various sizes in lung tissue, with rupture of some alveolar septa, emphysema changes, and pulmonary interstitial fibrosis, as well as significant increases in the mRNA expression of FN, COL-I, and COL-III and the protein expression of FN, COL-I, COL-III, p-Smad3, and Smad3 in lung tissue (P<0.05) . Compared with the SB431542 inhibitor control group, the SB431542 inhibitor group had a relatively complete structure of lung tissue without marked nodules and with a small amount of exudate in alveolar space and the lumen of bronchioles, as well as significant reductions in the mRNA expression of FN, COL-I, and COL-III and the protein expression of FN, COL-I, COL-III, p-Smad3, and Smad3 in lung tissue (P<0.05) . There were no significant differences in the mRNA expression of FN, COL-I, and COL-III and the protein expression of FN, COL-I, COL-III, p-Smad3, and Smad3 between the model group and the SB431542 inhibitor control group (P>0.05) . Conclusion: SB431542 exerts an intervention effect on silicotic fibrosis by blocking the TGF-β/Smad3 signaling pathway and reducing the expression of the downstream fibrosis factors FN, COL-I, and COL-III.

Abstract
BACKGROUND Frozen-thawed embryo transfer (FET) has become a routine procedure in assisted reproductive technology (ART). In FET, although blastocysts cultured from thawed cleavage-stage embryos are associated with better perinatal outcomes. it may increase cycle cancellation due to no suitable embryo to transfer. The overall clinical outcomes following transfer of thawed cleavage-stage FET and blastocysts cultured from thawed cleavage-stage embryos in young and advanced age patients remains unclear. Therefore, we aimed to identify the optimal FET strategy in young and advanced age women who undergo FET. METHODS This retrospective study included 16,387 thaw cycles. We retrospectively analyzed data of couples who had completed the first FET cycle. Two FET strategies were studied: transfer of thawed cleavage-stage embryos (strategy A) or blastocysts cultured from thawed cleavage-stage embryos (strategy B). The clinical and neonatal outcomes of two FET strategies were compared in young (<35 years) and advanced (≥35 years) age women. RESULTS In young women, the clinical outcomes per transfer cycle were better in strategy B than strategy A. While the clinical pregnancy (59.29%, 52.60%) and live birth rates (49.37%, 43.88%) per thaw cycle were significantly higher in strategy A than in B. In women of advanced age, the clinical outcomes per transfer cycle were still better in strategy B than in A, and the clinical pregnancy (36.44%, 39.66%) and live birth rates (25.70%, 30.00%) per thaw cycle were significantly higher in strategy B than in A. CONCLUSIONS FET of blastocysts cultured from cleavage-stage embryos showed higher efficiency for per transfer cycle whether in younger or advanced age women. Whereas, when cycle cancellations due to no suitable embryo to transfer were considered, cleavage-stage FET was found to be more suitable for younger women, while FET of blastocysts cultured from cleavage-stage embryos was better suited for women of advanced age.

Abstract
To evaluate the efficiency and safety of SperMagic medium on stimulating the immotile spermatozoa in testicular sperm extraction (TESE) and absolute asthenozoospermia, 96 patients with TESE and 106 patients with absolute asthenozoospermia were enrolled in this study. The motile spermatozoa were detected in 47 TESE patients and 68 absolute asthenozoospermia and these patients were assigned to control group. The immotile spermatozoa in 49 TESE patients and 34 absolute asthenozoospermia were stimulated with SperMagic medium. Patients were treated by standard intracytoplasmic sperm injection (ICSI). There were no significant differences in fertilisation, cleavage, implantation, pregnancy, live birth and neonatal outcomes. SperMagic medium does not increase incidence of adverse neonatal outcomes and is a reliable tool for selection of viable spermatozoa in ICSI.

Abstract
Background The use of assisted reproductive technology (ART) has been reported to increase the incidence of monozygotic twinning (MZT) compared with the incidence following natural conception. It has been hypothesized that splitting of the inner cell mass (ICM) through a small zona hole may result in MZT. In this study, using a cohort of patients undergoing preimplantation genetic diagnosis/screening (PGD/PGS), we compared the clinical and neonatal outcomes of human 8-shaped blastocysts hatching with ICM incarceration with partially or fully hatched blastocysts, and attempted to verify whether this phenomenon increases the incidence of MZT pregnancy or negatively impact newborns. Methods This retrospective study included 2059 patients undergoing PGD/PGS between March 1, 2013, and December 31, 2015. Clinical and neonatal outcomes were only collected from patients who received a single blastocyst transfer after PGD/PGS (n = 992). A 25- to 30-μm hole was made in the zona of day 3 embryos by laser. The blastocysts were biopsied and vitrified on day 6. The biopsied trophectoderm (TE) cells were analyzed using different genetic methods. One tested blastocyst was thawed and transferred to each patient in the subsequent frozen embryo transfer cycle. All the biopsied blastocysts were divided into three types: 8-shaped with ICM incarceration (type I), partially hatched without ICM incarceration (type II), and fully hatched (type III). ICM/TE grading, clinical and neonatal outcomes were compared between the groups. Results The percentage of grade A ICMs in type I blastocysts (22.2%) was comparable to that in type III blastocysts (20.1%) but higher than that in type II blastocysts (4.5%). The percentage of grade A TEs in type I blastocysts (4.2%) was comparable to that in type II (3.6%) but lower than that in type III (13.5%). There were no significant differences in clinical pregnancy, MZT pregnancy, miscarriage, live birth, MZT births, and neonatal outcomes between the groups. Conclusions Compared to partially and fully hatched blastocysts, 8-shaped blastocysts with ICM incarceration showed relatively higher ICM and lower TE grades. ICM incarceration in 8-shaped blastocysts does not increase the incidence of MZT and has no negative effects on newborns in PGD/PGS patients.

Abstract
The present study aimed at detecting the association of ovine major histocompatibility complex class II (Ovar II) DRB1 gene second exon and susceptibility or resistance to hydatidosis in three sheep breeds of Sinkiang. The MHC-DRB1 second exon was amplified by polymerase chain reaction (PCR) from DNA samples of healthy sheep and sheep with hydatidosis. PCR products were characterized by the restriction fragment length polymorphism (RFLP) technique. Five restriction enzymes, Mval, Haelll, Sacl, Sacll, Hin1l, were used, yielding 14 alleles and 31 restriction patterns. Frequencies of patterns Mvalbc, Hin1lab, Sacllab, Haelllde, Haellldf, Haellldd (P < 0.01) in Kazakh sheep, Saclab (P < 0.05) in Duolang sheep, and Haelllab, Haelllce, Haelllde, Haelllee (P < 0.01) in Chinese Merino (Sinkiang Junken type) sheep, were significantly higher in healthy sheep compared with infected sheep. These results indicated a strong association between these patterns and hydatidosis resistance. In contrast, the frequencies of Mvalbb, Saclaa, Hinl lbb, Haelllef (P < 0.01) and Haelllab (P < 0.05) in Kazakh sheep, Saclbb, Haelllae, Hin1lab (P < 0.05), Haelllaa, Haelllbe, Haelllef (P < 0.01) in Duolang sheep, Sacllaa (P < 0.05) and Haelllbd, Hin1lbb, Haelllcf, Haelllef (P < 0.01) in Chinese Merino sheep (Sinkiang Junken type) were significantly lower in healthy sheep compared with infected sheep. This indicated a strong association between these patterns and hydatidosis susceptibility. In addition, sheep with the pattern of Haelllef demonstrated a high hydatidosis susceptibility (P < 0.01) in all three breeds, while sheep with the pattern Haelllde demonstrated significant hydatidosis resistance (P < 0.01) in Kazakh and Chinese Merino sheep (Sinkiang Junken type). These results suggest that the Ovar-DRB1 gene plays a role in resistance to hydatidosis infection in the three sheep breeds.

Abstract
The dwarf gene Rht3 derived from Tom Thumb variety, a Tibetan wheat of China, is a dominant gene with the insensitivity to gibberellic acid. Rht3 shows to depress alpha-amylase activity and hence enchance the resistance to preharvest sprouting mainly through its effect on the expression of alpha-Amy1. Near isogenic lines with Rht3 and their segregating population were analyzed by PCR and RFLP techonology. In RAPD analysis, out of 310 random primers (10 bp) screened, only three primers of UBC389, OPV-06 and S1060 revealed polymorphisms in NIL from 310 random primers. Fragments S1060(1900) and S1060(2000) amplified by primer S1060 were shown to be linked to Rht3 with a genetic distance 7.1 cM and 9.2 cM. Fifty-three probes specific for short arms of homoeologous group 4 were screened in RFLP analysis. Xpsr584, XksuF8 and Xcdo38 showed polymorphisms between the NIL. The linkage analysis indicateded that Xpsr584 was linked to Rht3 with a genetic distance 8.0 cM.
