Abstract
Objective:To investigate the efficacy of semicircular canal occlusion in the treatment of intractable Ménière's disease in stage 3 or 4.Method:Retrospective analysis of clincal date of twenty-nine patients who were referred to our institute and diagonsed with Ménière's disease. According to the preoperative staging of hearing, there were 12 cases in stage 3 and 17 cases in stage 4, and all patients underwent semicircular canal occlusion. The preoperative and postoperative frequency of vertigo, hearing, caloric test, functional level and tinnitus level were compared. Postoperative following-up period was 6-23 months, with an average of 13 months.Result:Postoperatively, vertigo was controlled effectively in all 29 cases, of which 26 cases(89.7%) were completely controlled and 3 cases(10.3%) were basic controlled. The hearing stabilized in 25 cases(86.2%), worse in 2 cases(6.9%) and improved in 2 cases(6.9%). The semicircular canal function of all patients were in low status by caloric test. The rate of tinnitus relief and functional improvement was 41.4%(12/29) and 96.6%(28/29).Conclusion:Semicircular canal occlusion is an effective measure for treatment of Ménière's disease in stage 3 or stage 4, especially in controlling vertigo and improving functional level, but the long-term follow-up is necessary.

Abstract
Migration and invasion enhancer 1 (MIEN1) is a membrane-anchored protein that is highly expressed in various types of cancer, and is correlated with the PI3K/AKT pathway. The aim of this study was to investigate the expression of MIEN1 and its clinical pathological significance in breast cancer. We used immunohistochemical staining to examine the expression of MIEN1 in 40 samples of human breast cancer tissue and 10 samples taken from regions adjacent to normal breast tissue. The rate of detection of MIEN1 protein was 67.5%, which was significantly higher than that in adjacent non-cancerous breast tissue (0%, P < 0.05). The expression of MIEN1 correlated with age, World Health Organization grade, and lymph node metastasis, but not with tumor size or family history of cancer. Kaplan-Meier survival analysis showed that patients with positive MIEN1 protein expression had a lower overall survival rate than patients who did not express MIEN1. Downregulation of MIEN1 suppressed the expression of matrix metallopeptidase 9 by downregulating the expression of protein kinase B (also known as AKT) in breast cancer cells. Our results indicate that MIEN1 overexpression may facilitate migration and invasion in breast cancer, and MIEN1 is a potential molecular target for cancer chemotherapy.

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
Objective: To explore the impact of patient reported outcome of tyrosine kinase inhibitor (TKI) related side effects on daily life in Chinese patients with chronic myeloid leukemia (CML) in the chronic phase (CP). Methods: From May to November in 2014, anonymous questionnaires were distributed to adult CML patients who were receiving TKI treatment in China. The impact of TKI-related side effects on daily life were assessed by the score of 1 (no impact) to 5 (high impact) from patient self-report. Results: Data from 731 respondents in the CP who reported the score of the impact of TKI-related side effects on daily life were collected. 407 (56%) were male. The median age was 41 years (range, 18 to 88 years). 560 (77%) started TKI treatment within 1 year after diagnosis. With a median treatment duration of 3 years (range, <1 to 13 years), 549 (75% ) respondents achieved a complete cytogenetic response (CCyR) and 301 (41%) achieved a complete molecular response (CMR). The most common TKI-related adverse effects were edema (n=323, 44% ), fatigue (n=277, 38% ), gastrointestinal disorders (n=235, 32% ), skin color changes (n=142, 19% ), muscle cramps (n=137, 19% ), rash (n=105, 14% ), hepatic function abnormalities (n=91, 12%), weight gain (n=86, 12%), and cytopenia (n=59, 8%). Multivariate analyses showed that TKI treatment duration <4 years was the factor associated with fatigue; Edema was more observed in female, ≥40 years old and use of 1st generation TKI; Gastrointestinal disorders in use of 1st generation TKI; Hepatic function abnormalities and rash in use of 2nd generation TKI; Weight gain in female; Muscle cramps in long-term interval from diagnosis to therapy and use of 1st generation TKI; Low blood counts in use of generic TKI. There was no impact of TKI-related side effects on daily life in 218 (30%)respondents (1 score). 375 (51%)respondents reported their daily life were slightly or moderately decreased (2 or 3 score), while 138 (19%) significantly decreased (4 or 5 score). Multivariate analyses showed that female, ≥40 years old, use of generic TKI, TKI treatment duration <4 years were factors associated with negative effect on their daily life. When taking TKI related side-effects into considderation, secondary school and below, use of generic TKI, TKI treatment duration <4 years, edema, fatigue, gastrointestinal disorders, skin color changes, rash and hepatic function abnormalities, were factors associated with negative effect on their daily life. Conclusion: Edema, fatigue, gastrointestinal disorders, rash, skin color changes and hepatic function abnormalities were common TKI-related side effects and influenced CML patients' daily life in China. In addition, female, older age, lower education level, use of generic TKI and shorter TKI treatment duration were associated with negative impact on quality of life.

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
Flowers are the main sexual reproductive organs in plants. The shapes, colours and scents of corolla of plant flowers are involved in attracting insect pollinators and increasing reproductive success. The process of corolla senescence was investigated in Ipomoea purpurea (Convolvulaceae) in this study. In the research methods of plant anatomy, cytology, cell chemistry and molecular biology were used. The results showed that at the flowering stage cells already began to show distortion, chromatin condensation, mitochondrial membrane degradation and tonoplast dissolution and rupture. At this stage genomic DNA underwent massive but gradual random degradation. However, judging from the shape and structure, aging characteristics did not appear until the early flower senescence stage. The senescence process was slow, and it was completed at the late stage of flower senescence with a withering corolla. We may safely arrive at the conclusion that corolla senescence of I. purpurea was mediated by programmed cell death (PCD) that occurred at the flowering stage. The corolla senescence exhibited an obvious temporal rhythm, which demonstrated a high degree of coordination with pollination and fertilization.

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 Ubiquitin-specific protease 4 (USP4) is a deubiquitinating enzyme with key roles in the regulation of TGF-β1 signaling, suggesting its importance in tumorigenesis. However, the underlying mechanisms causing this are not entirely clear. In the present study, we investigated the effect of USP4 on invasion and tumorigenesis of breast cancer cells, and explored its mechanism. MATERIALS AND METHODS Effects of USP4 overexpression or USP4 silencing by small interfering RNA (USP4 siRNA) on invasion of breast cancer MDA-MB-231 and T47D cells in vitro was detected. Using siRNAs and inhibitors to examine the USP4 signaling pathway. RESULTS The migration and invasion assays showed that USP4 promotes human breast cancer cell migration and invasion by USP4 overexpression, and knockdown of USP4 by siRNA inhibits human breast cancer cell migration and invasion. Treatment with RLX siRNAs, TGF-β1 siRNAs, Smad2 siRNAs or BB94 (MMPs inhibitor) to USP4-overexpressing breast cancer cells revealed that USP4- induced RLX via TGF-β1 pathway promotes the cell migration and invasion. Further studies demonstrated that USP4-mediated TGF-β1 activation not only enhances the phosphorylation of Smad2 through TGF-β, but also directly upregulate matrix metalloproteinase (MMP)-9-mediated cell migration and invasion of breast cancer cells. CONCLUSIONS Therapies targeting the USP4 inhibits invasion of breast cancer cells via Relaxin/TGF-β1/Smad2/MMP-9 signal. These results indicate that USP4 is an attractive target for breast cancer therapy.

Abstract
The ECT2 (epithelial cell transforming sequence 2) oncogene acted as a guanine nucleotide exchange factor for RhoGTPases, and regulates cytokinesis; thus, it may play a role in the pathogenesis of gastric cancer. In this study, we investigated the expression ECT2 gene in tissues and serum of gastric cancer patients to explore its clinical significance. ECT2 mRNA expression levels in tissues and serum were examined by RT-PCR, and ECT2 protein expression in tissue was evaluated by Western blot, and was further validated by immunohistochemistry and enzyme-linked immunosorbent assay at serum level. ECT2 level was significantly increased in the GC tissues and serum compared to normal control. ECT2 expression was positively correlated with the histologic differentiation, stages of TNM, and lymph node metastasis in GC (P < 0.05). Our results suggest that ECT2 plays an important role during GC progression and it may become a new diagnostic marker and therapeutic molecular target for management of GC.

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
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
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.

Abstract
The aim of this study is to use Y-chromosome gene polymorphism method to investigate regional differences in genetic variation and population evolution history of the Chinese native cattle breeds. Six Y-chromosome short tandem repeat (Y-STR) loci (UMN0929, UMN0108, UMN0920, INRA124, UMN2404, and UMN0103) were analyzed using 1016 healthy and heterogenetic males and 90 females of 9 native cattle breeds (Qinchuan, Jinnan, Zaosheng, Luxi, Nanyang, Jiaxian, Dabieshan, Yanbian, and Menggu) in China. Allele frequency and gene diversity were calculated for the various populations. The results indicated that Y-STRs in the 6 loci have polymorphisms and genetic diversity in Chinese cattle populations. The genetic diversity analysis revealed that the Chinese cattle populations have a close genetic relationship. The analysis of INRA124, UMN2404, and UMN0103 loci revealed the original history of Chinese cattle because of which cattle belonging to Bos taurus or Bos indicus could be determined. Interestingly, a declining zebu introgression was displayed from South to North and from East to West in the Chinese geographical distribution, which implied that cattle population from various regions of China had been subjected to somewhat different evolutionary history. This conclusion supported other evidences such as earlier archaeological, historical research, and blood protein polymorphism analysis.

Abstract
Beef cattle breeding programs focus on improving important economic traits, including growth rates, and meat quantity and quality. Molecular marker-assisted selection based on genetic variation represents a potential method for breeding genetically improved livestock with better economic traits. Smoothened (SMO) protein is a signal transducer that contributes to the regulation of both osteogenesis and adipogenesis through the hedgehog pathway. In this study, we detected polymorphisms in the bovine SMO gene of Qinchuan cattle, and we analyzed their associations with body measurement traits (BMTs) and meat quality traits (MQTs). Using DNA sequencing and polymerase chain reaction-restriction fragment length polymorphism, 3 novel single nucleotide polymorphisms were identified in the SMO gene of 562 cattle: 1 G > C mutation on exon 9 (G21234C) and 2 C > T mutations on exon 11 (C22424T and C22481T). Association analysis showed that polymorphisms on both the G21234C and C22424T loci significantly affected certain BMTs and MQTs (P < 0.05 or P < 0.01), whereas those on the C22481T locus did not (P > 0.05). Therefore, the SMO gene could be used as a candidate gene to alter BMTs and MQTs in Qinchuan cattle or for marker-assisted selection to breed cattle with superior BMTs and MQTs.

Abstract
We constructed a prokaryotic expression vector expressing the Mycobacterium tuberculosis protein TB16.3, as well as 3 other proteins, including TB15.3, CFP-10, and Rv2626C, which were purified and analyzed for their effectiveness as detection antibodies. The TB16.3 genes of M. tuberculosis H37Rv genomic DNA were amplified by polymerase chain reaction, inserted into the expression vector pET-30a, and expressed in Escherichia coli. An enzyme-linked immunosorbent assay was used to detect the 4 M. tuberculosis antibodies. Engineered E. coli bacteria expressing TB16.3 and the 3 other proteins were constructed and found mainly to be soluble. For recombinant TB16.3 proteins, serum samples of 118 tuberculosis (TB) patients and 96 healthy controls were analyzed. Sensitivity, specificity, and adjusted concordance rate for the TB16.3 antibody were 72.9, 86.5, and 79.6%, respectively. The positive rate of Rv2626C antibody in TB patients (44.1%) was significantly lower than that in normal controls (75.0%, χ(2) = 20.8, P < 0.01). TB15.3 and TB16.3 were used for simultaneous detection and showed sensitivity, specificity, and repeatability rates of 69.4, 96.9, and 83.7%. The antibody positive rate and specificity for patients with lung disease was 9.6 and 90.4%, respectively. TB15.3 and TB16.3 were mixed and detected simultaneously. Combined with the results for TB15.3, the sensitivity, specificity, and concordance rates were 82.2, 95.9, and 88.9%, respectively. The concordance rate was the highest value observed. Target genes were cloned into a host strain and expressed successfully. The TB16.3 recombinant protein may be used as a new serological antigen for tuberculosis diagnosis.

Abstract
The female reproductive cycle is gated by the circadian timing system and may be vulnerable to disruptions in the circadian system. Prior work suggests that vasoactive intestinal peptide (VIP)-expressing neurons in the suprachiasmatic nucleus (SCN) are one pathway by which the circadian clock can influence the estrous cycle, but the impact of the loss of this peptide on reproduction has not been assessed. In the present study, we first examine the impact of the genetic loss of the neuropeptide VIP on the reproductive success of female mice. Significantly, mutant females produce about half the offspring of their wild-type sisters even when mated to the same males. We also find that VIP-deficient females exhibit a disrupted estrous cycle; that is, ovulation occurs less frequently and results in the release of fewer oocytes compared with controls. Circadian rhythms of wheel-running activity are disrupted in the female mutant mice, as is the spontaneous electrical activity of dorsal SCN neurons. On a molecular level, the VIP-deficient SCN tissue exhibits lower amplitude oscillations with altered phase relationships between the SCN and peripheral oscillators as measured by PER2-driven bioluminescence. The simplest explanation of our data is that the loss of VIP results in a weakened SCN oscillator, which reduces the synchronization of the female circadian system. These results clarify one of the mechanisms by which disruption of the circadian system reduces female reproductive success.

Abstract
We constructed a Mycobacterium tuberculosis vector expressing CFP-10 and Rv2626c to examine the expression of these proteins in Escherichia coli as well as their immunoreactivity. The CFP-10 and Rv2626c genes were amplified from tuberculosis H37Rv genomic DNA using polymerase chain reaction. They were ligated into the expression vector PET30a and expressed in E. coli. Histidine tag nickel column chromatography was used to purify the recombinant protein. An enzyme-linked immunosorbent assay (ELISA) was used for detection. In our E. coli-engineered bacteria containing a CFP10 and Rv2626c plasmid, the target protein was found mainly to be in the soluble form. We formed mixed antigens of the recombinant CFP10 and Rv2626c proteins. ELISA results showed that in 214 blood samples, the positive rate was 77.1%. The target gene was successfully expressed in the host strain. Mixed antigens of the recombinant CFP-10 and Rv2626c proteins can be used as a combination antigen in the serological diagnosis of tuberculosis.
