Abstract
Objective: To evaluate the feasibility of combining simultaneous triple semicircular canal plugging (TSCP) and cochlear implantation (CI) to treat vertigo and hearing loss in advanced Meniere's disease(MD) patients, so as to provide an alternative surgical procedure for treating this disorder. Methods: Data from seven patients, who were referred to our hospital and diagnosed with unilateral MD strictly meeting the criteria issued by Chinese Academy of Otolaryngology-Head and Neck Surgery Committee (2006), from Jan. 2015 to Jan. 2016, were retrospectively analyzed in this work. Seven patients, in whom the standardized conservative treatment had been given for at least one year and frequent vertigo still occurred, underwent simultaneous TSCP and CI under general anesthesia via mastoid approach. Postoperative follow-up time was more than six months. Vertigo control and auditory function were measured. Pure tone audiometry, speech perception scores, caloric test, head impulse test (HIT), and vestibular evoked myogenic potential (VEMP) were performed for evaluation of audiological and vestibular functions. Results: All patients had bilateral severe sensorineural hearing loss preoperatively. One side hearing loss was due to MD and another side was due to reasons including sudden sensorineural hearing loss, mumps and other unknown reason. The total control rate of vertigo in seven MD patients was 100.0% in the six-month follow-up, with complete control rate of 85.7% (6/7) and substantial control rate of 14.3% (1/7). Improved hearing threshold and speech perception scores were observed in all study participants. Postoperative average aided hearing threshold was 32.5 dBHL, the average monosyllabic word score was 42.6% and speech perception scores of sentences tested in quiet was 52.3%. Tinnitus improved in five cases, and no significant change in two patients. Post-operatively, all patients suffered from temporary vertigo and balance disorders. Vertigo was disappeared in all patients within 3-5 days, while, an average recovery time of balance disorders was 19.7 days. Six months after treatment, loss of semicircular canal function by caloric test was found in the operation side of all patients and no change in cVEMP or oVEMP test was noted. All patients had no facial paralysis, cerebrospinal fluid leakage, and other complications. Conclusions: A combined approach of TSCP and CI which could control vertigo effectively and improve hearing loss and tinnitus represents an effective and safe therapy for some advanced MD patients.

Abstract
Chromosomal abnormality is the most common genetic cause of infertility. Infertility, as a psychological problem, has received an increasing amount of attention. Psychological interventions have been shown to have beneficial effects on infertile patients with chromosomal abnormalities. The present study explored reproductive outcome of male carriers of chromosomal abnormalities, who accepted genetic counseling and psychological support. Cytogenetic analysis was performed using cultured peripheral blood lymphocytes and G-banding. The detection rate of chromosomal abnormalities was 10.3% in pre-pregnancy counseled males, with polymorphisms being most common, followed by 47,XXY and balanced translocation. Follow-up of 170 carriers with normozoospermia, after 3 years, showed that 94.7% of the cases resulted in live births. In the carriers of polymorphisms, balanced translocation, inv(9), Robertsonian translocation, inversion, and 47,XYY, live birth rates were 96.8, 85.7, 100, 83.3, 75, and 100%, respectively. Follow-up of 54 carriers with oligozoospermia or azoospermia, after 3 years, showed that 14.8% of the cases resulted in live births. In the carriers of 47,XXY with severe oligozoospermia or azoospermia, 80 or 5.9% of the cases resulted in live births, respectively. Therefore, timely psychological support would be beneficial and multidisciplinary approach should be preferentially considered for the management of individuals with chromosomal abnormalities.

Abstract
Compound homozygous or heterozygous mutations in WFS1 can lead to autosomal recessive Wolfram syndrome (WS), and heterozygous mutations in WFS1 can lead to autosomal dominant non-syndromic low frequency sensorineural hearing loss (LFSNHL). In addition, mutations in the WFS region has relationship with diabetes and psychiatric diseases. In this paper, we provide an overview of genetic research with different phenotypes, including WS and LFSNHL.

Abstract
Objective: To investigate the prognostic factors relevant to acute low-tone sensorineural hearing loss (ALHL). Methods: 196 adult ALHL patients, including 82 males and 114 females with mean age of (43.1±14.3)years old were included. All patients received the same therapy and were evaluated the curative effect. To evaluate the impact factors on the prognosis of hearing, inclusive of age, gender, time delay before the first visit, degree of deafness, vestibular function, electrocochleogram, and the serum levels of thyroxines by SPSS 18.0 software. Results: Of those 196 patients with ALHL, 124(63.3%) were recovery, 5(2.6%) were excellent better, 42(21.4%) were better, and 25 (12.8%) were poor, with a total effective rate of 87.2%. Among 15 (12.1%) who recurred the hearing loss, 2 developed into Meniere's disease during the follow-up. The mean age of patients with poor hearing effect was significantly older than that of other patients (P<0.05). No relativity was found between gender and hearing curative effect. There existed a statistical difference in total effective rate among subjects with different histories (P<0.05). In addition, the recovery rate was significantly different between groups, i. e., the course of disease was less than 14 days, between 14 days and 6 months, and between 6 months and 2 years (P<0.05). There was no statistical significance in total effective rate among different degrees of deafness (P>0.05). However, in term of the recovery rate, the difference was statistical significance (P<0.05). The recovery rate in patients with mild hearing loss was higher than that in middle or heavy hearing loss (both P<0.05). Among patients with mild deafness, the recovery rate in patients whose history was less than 3 months was significantly higher than that more than 3 months (P<0.05). For moderate deafness patients, the recovery rate in patients whose history was less than 7 days was significantly higher than that more than 1 month (P<0.05). There were statistical differences in hearing effect of 130 (66.3%) patients with abnormal vestibular function in comparison to that with normal vestibular function (χ2=15.1, P<0.05). There were 17(8.7%) patients with abnormal electrocochleogram combined with abnormal vestibular function, and the hearing effects were all poor. There were 45 (23.0%) patients with abnormal thyroxine levels in serum, which was significant higher than that in health adults of 5.9%(χ2=7.26, P<0.01). There was no significant difference in hearing prognosis between patients with abnormal and normal thyroxine levels (χ2=2.51, P>0.05). Conclusions: With respect to ALHL, the hearing effect is associated significantly with the history. The severity of hearing loss is negative prognostic factor for hearing recovery. Age, vestibular function, and electrocochleogram might predict hearing recovery. Gender and thyroxine levels couldn't predict the hearing prognosis, although there is a high incidence rate in patients with ALHL.

Abstract
Estrogen receptor (ER) and progesterone receptor (PR) are two important members of steroid receptors family, an evolutionarily conserved family of transcription factors. Upon binding to their ligands, ER and PR enter cell nucleus to interact with specific DNA element in the context of chromatin to initiate the transcription of diverse target genes, which largely depends on the timely recruitment of a wide range of cofactors. Moreover, the interactions between steroid hormones and their respective receptors also trigger post-translational modifications on these receptors to fine-tune their transcriptional activities. Besides the well-known phosphorylation modifications on tyrosine and serine/threonine residues, recent studies have identified several other covalent modifications, such as ubiquitylation and sumoylation. These post-translational modifications of steroid receptors affect its stability, subcellular localization, and/or cofactor recruitment; eventually influence the duration and extent of transcriptional activation. This review is to focus on the recent research progress on the transcriptional activation of nuclear ER and PR as well as their physiological functions in early pregnancy, which may help us to better understand related female reproductive diseases.

Abstract
The aim of this paper is to analyze the probabilistic structure for a rather general class of bilinear models systematically. First, the sufficient and necessary conditions for stationarity are given with a concise expression. Then both the autocovariance function and the spectral density function are obtained. The Yule–Walker-type difference equations for autocovariances are derived by means of the spectral density function. Concerning the second-order probabilistic structure, the model is similar to an ARMA model. The third-order probabilistic structure for the model is discussed and a group of Yule–Walker-type difference equations for third-order cumulants are discovered.

Abstract
Objective:To investigate the ultrahigh-frequency(UHF) hearing thresholds in middle-aged and elderly healthy subjects .Method: Healthy subjects(age range: 50-69 ) were divided into two groups,i.e.50-59 year-old group and >59-69 year-old group.Each subject was tested with both conventional-frequency(0.25,0.50,1.00,2.00,4.00,6.00 and 8.00 kHz) and ultrahigh-frequency(9.0,10.0,11.5,12.5,14.0,16.0,18.0,and 20.0 kHz) audiometry.UHF was performed twice to evaluate the reliability.The best hearings among 20-29 aged healthy adults were considered as normal controls.Results:Seventy five middle-aged and elderly subjects were included,with 39 subjects(78 ears) being 50-59 years old and 36(72 ears) being >59-69 year-old.Eighteen subjects(36 ears) aging from 20 to 29 were considers as controls.For the conventional-frequency,the hearing thresholds in middle-aged and elderly people were significantly higher than those in young people(all P<0.05),especially at ≥4 kHz.Although the conventional-frequency thresholds in >59-69 year-old group were higher than those in 50-59 year-old,the difference was significant just at 4 kHz(P<0.05).The UHF thresholds in middle-aged and elderly people were significantly higher than those in young people(all P<0.05).The thresholds at 9,10,11.5 and 12.5 kHz in >59-69 year-old people were significantly increased than those in 50-59 year-old counterparts(all P<0.05).Hearing threshold at ≥12.5 kHz couldn't be detected in some subjects in middle-aged and elderly group.The response rate at UHF in >59-69 year-old people were just higher than that in 50-59 year-old counterparts (P>0.05),and none responded at 18 and 20 kHz.The standard deviations(SDs) for <14 kHz in 50-59 year-old and for <11.5 kHz in >59-69 year-old subjects,were both higher than that in 20-29 year old counterparts.Above 6 kHz,the SDs in 50-59 year-old subjects were significantly higher than those in >59-69 year-old subjects(all P<0.05).Conclusion:For middle-aged and elderly people,the hearing loss may occur from 4 kHz.Hearing thresholds at UHF were increased with age,and it might be used as an early indicator for age-induced hearing loss.However,the UHF sensitivity decreased as the frequency increased beyond 14 kHz.

Abstract
Objective:To investigate frequency and position characteristics of the vestibular dysfunction in vestublar neuritis patients. Method:Colaric test (CT), head impulse test (HIT), cervical vestibular evoked myogenic potential (cVEMP) and ocular vestibular evoked myogenic potential (oVEMP) were applied in 43 vestublar neuritis patients to assess their vestublar dysfunction. Superior vestublar nerve (S-VN), inferior vestibular nerve (I-VN), total vestibular nerve (T-VN) and each vestibular end organ incidence rate were calculated and statistically analyzed. Result:CT incidence rate (93.0%) was statistically higher than that of HIT (72.1%) (P<0.01). Total frequency incidence rate (72.1%) was statistically higher than that of low frequency (20.9%) (P<0.01). No high frequency only case was observed. The incidence rate of S-VN only, I-VN only and T-VN was 44.2%, 4.7% and 51.2% respectively. Among them, the incidence rate of I-VN was significantly lower than the others (P<0.01). The incidence rate of vestibular end organs was 17.4% (S-SCC), 44.2% (H-SCC), 20.9% (P-SCC), 39.5% (utricule) and 26.7% (saccule) respectively. The incidence rate of H-SCC was remarkably higher than the other semicircular canals (P<0.01). The difference between utricule and saccule was not statistically significant. Conclusion:The semicricular canal dysfunction in vestibular neuritis patients mainly involves total frequency of vestibular function, low frequency is more common than high frequency. Total vestibular nerve and single S-VN are mostly involved in vestibular neuritis.

Abstract
Background Extra-nodal marginal zone B cell lymphoma of mucosa-associated lymphoid tissue originating in the liver is less common. Case presentation We described the clinical presentation, immunohistochemistry, and immunophenotypes of this lymphoma, which was misdiagnosed with tiny hepatic carcinoma in a 44-year-old woman with hepatitis C; the patient underwent left lateral sectionectomy. The immunophenotype identified the most of the lymphoid cells as positive CD20, CD34, Ki67, CD3, CD4, CD79a, CD45RO, MUM-1, and CD5 and negative CD10, CD15, CD30, ACT, CK, CRO, DES, and HMB45. The diagnosis of primary hepatic mucosa-associated lymphoid tissue (MALT) was made by histology after surgery; the patient went through the excellent recovery with no chemotherapy and is disease free for 27 months. Conclusions Primary hepatic MALT is less common with incidental finding; local resection is beneficial due to its oncological indolence.

Abstract
OBJECTIVE To study the effect of sub-anesthetic doses of isoflurane and propofol on the postoperative cognitive function of rats with mild cognitive impairment (MCI) following orthopedic operation. METHODS Male sprague-dawley rats (n=100) were randomly divided into sham group and model group.Bilateral carotid artery was separated with no bilateral narrowing in the sham operation group while bilateral carotid artery was occluded in model group.After 30 days, Morris Water Maze test were used to select MCI rats. The proportion of the value that average escape latency in model group minused average escape latency in sham group less than 20% was marked as MCI rats. After 36 days, the rats with mild cognitive impairment were randomly divided into 4 groups (n=18). Iso group: Isoflurane (1.9%) 3 h, combination group: propofol (20 mg·kg(-1)·h(-1))+ isoflurane (1%) 3 h. Inhibitor with these two groups were respectively used the selective KCC2 inhibitor-DIOA 30 μg 15 min before anesthesia. Then rats received an open tibial fracture on the hind paw with an intramedullary fixation. The rats in sham group were only sutured skin incision. At the day 7 postoperatively, the Y maze test were used to test the change of cognition, nissl staining was used to observe the neurons apoptosis. Immunofluorescence was adopted to observe the neurons expressing GAD67/KCC2 and Western blot were applied to observe the protein level of KCC2 in hippocampus. RESULTS The rate of time spent in novel arm, the number of surviving neurons, the number of neurons expressing GAD67/KCC2 and protein expression levels of KCC2 in hippocampus in combination group were (52.94±2.04)%, (176.81±13.07), (196.72±8.02), (80.67±3.46)% respectively. The indexes in sham group were (53.44±2.45)%, (183.79±10.88), (207.45±13.17), (81.42±3.59)%, respectively. There was no significant difference compared with the sham group (all P>0.05). However these indexes in above two groups were higher than that in Iso group( (36.10±1.57)%, (97.21±8.23), (158.94±13.47), (43.22±4.91)%, all P<0.05). The indexes in inhibitor with Iso groups, combination group was lower compared with groups without inhibitor respectively (all P<0.05). CONCLUSION Compared with isoflurane, sub-anesthetic doses of isoflurane and propofol has no significant effect on postoperative cognition in rats with MCI, and its mechanism is to maintain KCC2 expression in hippocampus.

Abstract
OBJECTIVE Pyruvate can reduce lipid peroxidation, which plays a critical role in organ injury, in various models. However, it is not fully understood if this inhibition occurs in resuscitation of hemorrhagic shock (HS). This study examines effects of pyruvate Ringer solution (PR) in this respect in rats. METHODS Rats, subjected to 45% blood loss, were randomly allocated to the 3 groups (n = 18): HS with no fluid resuscitation (group NR), HS resuscitated with lactated Ringer solution (LR) (group LR), and HS resuscitated with PR (group PR). Mean arterial pressure, plasma levels of thiobarbituric acid reactive substances (TBARS), and superoxide dismutase were measured at various time points until 360 minutes after hemorrhage. Visceral organs were harvested at the end for evaluations of the TBARS, antioxidant enzyme, and tissue water content. Other 54 rats with identical procedures without sampling were documented for 24-hour survival rates (n = 18) after fluid resuscitation. RESULTS Pyruvate Ringer solution significantly increased mean arterial pressure and decreased blood TBARS levels after lethal HS. It also reduced TBARS concentrations and glutathione peroxidase activities but significantly enhanced glutathione reductase activities in most organs and greatly improved the ratios of reduced glutathione over oxidized glutathione in various organs in group PR, compared to group LR. Furthermore, PR significantly improved various organ function and water contents relative to LR. Group PR showed a more than 2-fold higher 24-hour survival rate of group LR. CONCLUSIONS Pyruvate Ringer solution alleviated organ edema and injury and prompted survival partially through inhibition of lipid peroxidation in various organs in severe HS rats.

Abstract
Several studies have focused on the association between the ERCC2 rs13181 polymorphism and glioma risk, but the results were inconclusive. We aimed to conduct a meta-analysis to investigate the role of ERCC2 rs13181 on the risk of glioma. We searched and collated the relevant studies in both Chinese and English through the PubMed, Web of Science, Cochrane Library, and EMBASE databases published through June 1, 2014. A total of 11 studies for ERCC2 rs13181 were selected; these included 3456 glioma cases and 4957 controls. Using fixed-effects model analysis, we found that no significant difference could be identified between the ERCC2 rs13181 polymorphism and the risk of glioma. Subgroup analysis showed that the ERCC2 rs13181 GT and TT genotypes were significantly associated with an increased risk of glioma in the Chinese population [odds ratio (OR) = 1.47, 95% confidence interval (CI) = 1.17-1.85; and OR = 1.50, 95%CI = 1.02-2.22, respectively], but no significant increased risk of glioma was detected with these genotypes in the Caucasian populations. No publication bias was identified in this meta-analysis. Our meta-analysis strongly suggested that ERCC2 rs13181 was associated with a higher susceptibility to glioma in the Chinese population.

Abstract
AIM: To investigate whether dimethyl sulfoxide (DMSO) inhibits gut inflammation and barrier dysfunction following zymosan-induced systemic inflammatory response syndrome and multiple organ dysfunction syndrome.
METHODS: Sprague-Dawley rats were randomly divided into four groups: sham with administration of normal saline (SS group); sham with administration of DMSO (SD group); zymosan with administration of normal saline (ZS group); and zymosan with administration of DMSO (ZD group). Each group contained three subgroups according to 4 h, 8 h, and 24 h after surgery. At 4 h, 8 h, and 24 h after intraperitoneal injection of zymosan (750 mg/kg), the levels of intestinal inflammatory cytokines [tumor necrosis factor-alpha (TNF-α) and interleukin (IL)-10] and oxides (myeloperoxidase, malonaldehyde, and superoxide dismutase) were examined. The levels of diamine oxidase (DAO) in plasma and intestinal mucosal blood flow (IMBF) were determined. Intestinal injury was also evaluated using an intestinal histological score and apoptosis of intestinal epithelial cells was determined by deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The intestinal epithelial tight junction protein, ZO-1, was observed by immunofluorescence.
RESULTS: DMSO decreased TNF-α and increased IL-10 levels in the intestine compared with the ZS group at the corresponding time points. The activity of intestinal myeloperoxidase in the ZS group was higher than that in the ZD group 24 h after zymosan administration (P < 0.05). DMSO decreased the content of malondialdehyde (MDA) and increased the activity of superoxide dehydrogenase (SOD) 24 h after zymosan administration. The IMBF was lowest at 24 h and was 49.34% and 58.26% in the ZS group and ZD group, respectively (P < 0.05). DMSO alleviated injury in intestinal villi, and the gut injury score was significantly lower than the ZS group (3.6 ± 0.2 vs 4.2 ± 0.3, P < 0.05). DMSO decreased the level of DAO in plasma compared with the ZS group (65.1 ± 4.7 U/L vs 81.1 ± 5.0 U/L, P < 0.05). DMSO significantly preserved ZO-1 protein expression and localization 24 h after zymosan administration. The TUNEL analysis indicated that the number of apoptotic intestinal cells in the ZS group was much higher than the ZD group (P < 0.05).
CONCLUSION: DMSO inhibited intestinal cytokines and protected against zymosan-induced gut barrier dysfunction.

Abstract
Here, we detected 2 SNPs, A85C and T335C, that were located on the 3rd exon and the 3 untranslated regions of the bovine Osteocrin gene, respectively, using 413 Qinchuan cattle DNA samples. PCR-SSCP and DNA sequencing methods were specifically used. Three genotypes (AA, AC, and CC) were found at A85C; yet, only 2 genotypes (TC and CC) were found at T335C. Association analysis showed that both loci were associated with certain meat quality traits, including back fat thickness and loin muscle area. At the A85C locus, individuals with the CC genotype had greater back fat thickness. In comparison, at the T335C locus, individuals with the TC genotype had greater back fat thickness and a larger loin muscle area. Therefore, these 2 SNPs could be used as genetic markers to enhance Qinchuan cattle breeding programs.

Abstract
Compared with conventional DGA (dissolved gas analysis) method for on-line monitoring of power transformers, FBG (fiber Bragg grating) hydrogen sensor represents marked advantages over immunity to electromagnetic field, time-saving, and convenience to defect location. Thus, a novel FBG hydrogen sensor based on Pd/Ag (Palladium/Silver) along with polyimide composite film to measure dissolved hydrogen concentration in large power transformers is proposed in this article. With the help of Pd/Ag composite coating, the enhanced performance on mechanical strength and sensitivity is demonstrated, moreover, the response time and sensitivity influenced by oil temperature are solved by correction lines. Sensitivity measurement and temperature calibration of the specific hydrogen sensor have been done respectively in the lab. And experiment results show a high sensitivity of 0.055 pm/(μl/l) with instant response time about 0.4 h under the typical operating temperature of power transformers, which proves a potential utilization inside power transformers to monitor the health status by detecting the dissolved hydrogen concentration.

Abstract
Ballistic thermal transport properties by phonons in three dimensional (3D) periodic nanostructures is investigated. Results show that thermal transport properties in 3D periodic nanostructures can be efficiently tuned by modulating structural parameters of systems. When the incident frequency is below the first cutoff frequency, the quasi/formal-periodic oscillations of the transmission coefficient versus the periodic number/length can be observed. When the incident frequency is above the first cutoff frequency, however, these quasi/formal-periodic oscillations cannot be observed. As the periodic number is increased, the thermal conductance undergoes a prominent transition from the decrease to the constant. We also observe other intriguing physics properties such as stop-frequency gaps and quantum thermal conductance in 3D periodic nanostructures. Some similarities and differences between 2D and 3D periodic systems are identified.

Abstract
Tuberculosis (TB) outbreak occurred in a boarding middle school of China. We explored its probable sources and quantified the transmissibility and pathogenicity of TB. Clinical evaluation, tuberculin skin testing and chest radiography were conducted to identify TB cases. Mycobacterium tuberculosis isolates underwent genotyping analysis to identify the outbreak source. A chain-binomial transmission model was used to evaluate transmissibility and pathogenicity of TB. A total of 46 active cases were ascertained among 258 students and 15 teachers/staff, an attack rate of 16.8%. Genetic analyses revealed two groups of M. tuberculosis cocirculating during the outbreak and possible importation from local communities. Secondary attack rates among students were 4.1% (2.9%, 5.3%) within grade and 7.9% (4.9%, 11%) within class. An active TB case was estimated to infect 8.4 (7.2, 9.6) susceptible people on average. The smear-positive cases were 28 (8, 101) times as infective as smear-negative cases. Previous BCG vaccination could reduce the probability of developing symptoms after infection by 70% (1.4%, 91%). The integration of clinical evaluation, genetic sequencing, and statistical modeling greatly enhanced our understanding of TB transmission dynamics. Timely diagnosis of smear-positive cases, especially in the early phase of the outbreak, is the key to preventing further spread among close contacts.

Abstract
The foreign-body response to biomaterials compromises the performance of many biomedical devices by severe fibrosis and limited neovascularization. Mesenchymal stem cells are known to secrete cytokines for treating inflammatory conditions. In this study, we aim to investigate whether the paracrine products of adipose-derived mesenchymal stem cells (ADSCs) can affect the microenvironment of biomaterials and improve tissue responses to biomaterial implants. A model system was built by loading ADSC spheroids into a macroencapsulation device composed of polytetrafluoroethylene (PTFE) filtration membranes. Soluble ADSC factors that diffused out of the device in vitro promoted the angiogenetic activity of endothelial cells and affected the secretion pattern of macrophages. In vivo study was carried out by subcutaneously embedding blank or ADSC-laden devices in rats. Following a 4 week implantation, the ADSC-laden devices were better vascularized and induced significantly less fibrotic tissue formation in comparison to the non-cellular controls. This study may facilitate our understanding of foreign-body responses and suggest new ways to improve the tissue reaction of biomedical devices for cell-based therapy.

Abstract
Sonic hedgehog (Shh) functions as a conserved morphogen in the development of various organs in metazoans ranging from Drosophila to humans. Here, we have investigated the potential roles and underlying mechanisms of Shh signaling in murine placentation. Immunostaining revealed the abundant expression of the main components of Shh pathway in both the trophectoderm of blastocysts and developing placentas. Disruption of Shh led to impaired vascularogenesis of yolk sac, less branching and malformation of placental labyrinth, thereby leading to a robust decrease in capacity of transplacental passages. Moreover, placenta-specific gene incorporation by lentiviral transduction of mouse blastocysts and blastocyst transplantation robustly knocked down the expression of Gli3 and Gli2 in placenta but not in embryos. Finally, Gli3 knockdown in Shh−/− placentas partially rescued the defects of both yolk sac and placental labyrinth, and robustly restored the capacity of transplacental passages. Gli2 knockdown in Shh+/− placentas affected neither the capacity of tranplacental passages nor the vascularogenesis of yolk sac, however, it partially phenocopied the labyrinthine defects of Shh−/− placentas. Taken together, these results uncover that both Shh/Gli2 and Shh/Gli3 signals are required for proper development of murine placentas and are possibly essential for pregnant maintenance.
