Abstract
Objective:To analyze the characteristics of sleep quality and its correlation with the clinical features and hearing curative effects in patients with unilateral idiopathic sudden sensorineural hearing loss (ISSHL). Method:Pittsburgh sleep quality index (PSQI) was applied to evaluate the sleep quality of unilateral ISSHL patients in our department. Patient group is divided into poor sleep quality subgroup (total PSQI score>7 points) and normal sleep subgroup (total PSQI score≤7 points). The differences of Patient group and two subgroups between hearing curative effect in the 30 days after treatment and sleep quality scores were compared and analyzed. Questionnaire survey was applied to control group, which contained 70 healthy people with normal hearing level and age matched. Result:A total of 75 cases were collected. To compare with control group, there were statistical difference in the scores of subjective sleep quality, habitual sleep efficiency, sleep disturbance and PSQI before treatment and in the score of habitual sleep efficiency after the treatment for 30 d (P<0.05). The sleep quality between poor sleep quality subgroup and normal sleep subgroup, total therapeutic effect after treatment for 30 d was no significant difference (P>0.05). The proportion for poor sleep quality were no statistically significant differences in the different efficacy of two subgroups (P>0.05). Two subgroups before treatment, in addition to sleep duration, there were statistically significant in all the sleep quality dimensions (P<0.05); after treatment for 30 d, in addition to subjective sleep quality, sleep duration, all have statistical difference (P<0.05). The poor sleep quality subgroup in the case group compared before and after treatment for 30 d, there was statistically significant in subjective sleep quality (P<0.05). The sleep disturbance before treatment, the sleep duration and PSQI scores after treatment for 30 d were associated with clinical features in patients with unilateral ISSHL (P<0.05). Conclusion:The sleep quality of patients with Unilateral SSNHL was significantly lower than that of normal hearing patients, the sleep quality had no significant effect on the general efficacy of unilateral SSNHL, but some sleep quality dimensions are associated with the clinical features before and after treatment.

Abstract
Objective: To prospectively investigate the changes in nutritional status of patients with malignant tumors during hospitalization by using nutritional risk screening (NRS2002), and to analyze the correlation between the nutritional status and clinical outcomes . Methods: This was a prospective and parallel research done by multi-center collaboration from 34 hospitals in China from June to September 2014.Hospitalized patients with malignant tumors inthese departments (Department of Gastroenterology, respiratory medicine, oncology, general surgery, thoracic surgery and geriatrics)were investigated. Only the patients with age≥ 18 years and hospitalization time between 7-30 days were included. During hospitalization, the physical indexes of human bodywere measured, and the NRS 2002 scores, and monitored the nutritional support at the time points of admission and 24 hours before discharge were recorded.And whether there was a nutritional risk in hospitalized patients and its association with clinical outcomes were investigated. Results: A total of 2 402 patients with malignancies were enrolled in this study. Seventy fourpatients who did not complete NRS2002 were eliminated, and 2 328 patients were included. The number of the main diseases was the top five, including 587 cases of colorectal cancer, 567 cases of lung cancer, 564 cases of gastric cancer, 146 cases of esophageal cancer, and 119 cases of liver tumor. At the time of discharge, compared with admission, the BMI, body weight, grip and calf circumferences of patients with malignant tumor were significantly decreased (P<0.05). The total protein, albumin, prealbumin and hemoglobin were significantly lower than those at admission (P<0.05). In 2 328 patients who were completed nutritional risk screening, the rate of malnutrition at admission was 11.1% (BMI =18.5, 258/2 328) and the rate of malnutrition at discharge was 10.9% (BMI =18.5, 254/2 328), there were no significant differences (χ(2)=0.019 7, P=0.888). There were 1 204 patients with nutritional risk at admission (51.7%, NRS2002 score≥3)and 1 352 patients with nutritional risk at discharge (58.1%, NRS2002 score≥3), with significant differences (χ(2)=49.9, P<0.001). The incidence of nutritional risk in patients with colorectal, stomach, and lung tumors at discharge was significantly higher than that at admission (P<0.05). The infective complications and other complications of patients with nutritional risk were significantly greater than those without nutritional risk at admission and at discharge.ICU hospitalization stay of patients with nutritional risk was increased significantly than those without nutritional risk at admission(P=0.042). Hospitalization expenses of patients with nutritional risk was increased significantly than those of patients without nutritional risk at discharge(P<0.01). Conclusion: The patients with malignant tumor have a higher incidence rate of malnutrition at both admission and discharge and malnutritionhas correlation with adverse clinical outcomes.The aboveindicators did not improve significantly at discharge.Doctors should pay more attention to the nutritional status (screening and evaluation)of patients before discharge and use appropriate and adequate nutrition support in order to prevent the weight loss and improve the life quality of patients.

Abstract
To quantify the Li diffusion behavior in nanocrystalline anode materials for lithium-ion batteries (LIBs), a hybrid model of the first principles calculation and diffusion kinetics was developed. The dependence of the Li diffusion on the electronic structure, solute concentration, grain size and temperature was described for the nanocrystalline Li-Si system. In contrast to conventional polycrystalline materials in which the activation barrier for Li diffusion decreases with the increase of concentration before amorphization, there exists a coordination effect of the solute concentration and grain size on the Li diffusion in nanocrystalline materials. A maximum diffusion coefficient can be obtained in the nanocrystalline Li-Si by a combination of the concentration and grain size, which is increased by two orders of magnitude from that in the coarse-grained counterpart. The present work advanced the understanding of the Li diffusion mechanisms during lithiation/delithiation of LIBs and may facilitate the development of nanocrystalline anode materials.

Effect of early embryonic deletion of huntingtin from pyramidal neurons on the development and long-term survival of neurons in cerebral cortex and striatum. Neurobiol Dis 2017; 111:102-117.

Abstract
We evaluated the impact of early embryonic deletion of huntingtin (htt) from pyramidal neurons on cortical development, cortical neuron survival and motor behavior, using a cre-loxP strategy to inactivate the mouse htt gene (Hdh) in emx1-expressing cell lineages. Western blot confirmed substantial htt reduction in cerebral cortex of these Emx-httKO mice, with residual cortical htt in all likelihood restricted to cortical interneurons of the subpallial lineage and/or vascular endothelial cells. Despite the loss of htt early in development, cortical lamination was normal, as revealed by layer-specific markers. Cortical volume and neuron abundance were, however, significantly less than normal, and cortical neurons showed reduced brain-derived neurotrophic factor (BDNF) expression and reduced activation of BDNF signaling pathways. Nonetheless, cortical volume and neuron abundance did not show progressive age-related decline in Emx-httKO mice out to 24 months. Although striatal neurochemistry was normal, reductions in striatal volume and neuron abundance were seen in Emx-httKO mice, which were again not progressive. Weight maintenance was normal in Emx-httKO mice, but a slight rotarod deficit and persistent hyperactivity were observed throughout the lifespan. Our results show that embryonic deletion of htt from developing pallium does not substantially alter migration of cortical neurons to their correct laminar destinations, but does yield reduced cortical and striatal size and neuron numbers. The Emx-httKO mice were persistently hyperactive, possibly due to defects in corticostriatal development. Importantly, deletion of htt from cortical pyramidal neurons did not yield age-related progressive cortical or striatal pathology.

Abstract
Objective: To explore the clinical and electrophysiological features and prognosis of distal myasthenia gravis (MG). Methods: Data of MG patients in Beijing Tiantan Hospital from October 2016 to March 2017 were reviewed, including thorough neurological examinations, nerve conduction studies, repetitive nerve stimulations (RNS) and needle electromyographies. Distal MG patients were included and were analyzed as to their clinical and electrophysiological features and response to treatments. Results: Four patients (7.7%) could be classified as distal type among 52 definitely diagnosed MG patients. They had initial symptoms at age 36 to 64 and developed distal limb muscle weakness in the first month to 6 years after the onset of this disease. Hand muscles were preferentially involved in a non-uniform way. And one patient also had leg weakness on his tibialis anterior muscles. RNS showed a more significant decrement at slow rates in distal muscles, compared with proximal muscles. The baseline compound muscle action potentials (CMAP) of the distal affected muscles presented with slightly decreased or fluctuating amplitudes. Their weakness of ocular, bulbar, proximal and distal limb muscles improved generally after administration of acetylcholinesterase inhibitors or steroids plus acetylcholinesterase inhibitors. Electrophysiological reexaminations revealed increased baseline CMAPs, reduced decrement on RNS, and relief of myogenic changes on needle electromyography. Conclusions: Relatively prominent distal limb muscle weakness can be found in a minority of MG patients. Besides profound decrement on slow rate RNS, the involved distal muscles may have a characteristic decreased baseline CMAP, sometimes with a diurnal fluctuation. Distal MG responds well to regular treatments. Its short-term prognosis seems similar to that of common MG with proximal predominance.

Abstract
Bumetanide is a selective inhibitor of the Na+-K+-Cl--co-transporter 1(NKCC1). We studied whether bumetanide could affect axonal growth and behavioral outcome in stroke rats. Adult male Wistar rats were randomly assigned to four groups: sham-operated rats treated with vehicle or bumetanide, and ischemic rats treated with vehicle or bumetanide. Endothelin-1 was used to induce focal cerebral ischemia. Bumetanide administration (i.c.v.) started on postoperative day 7 and continued for 3 weeks. Biotinylated dextran amine (BDA) was injected into the right imotor cortex on postoperative day 14 to trace corticospinal tract (CST) fibers sprouting into the denervated cervical spinal cord. Nogo-A, NKCC1, KCC2 and BDNF in the perilesional cortex and BDA, PSD-95 and vGlut1 in the denervated spinal cord were measured by immunohistochemistry and/or Western blot. Behavioral outcome of rats was assessed by the beam walking and cylinder tests. The total length of CST fibers sprouting into the denervated cervical spinal cord significantly increased after stroke and bumetanide further increased this sprouting. Bumetanide treatment also decreased the expressions of NKCC1 and Nogo-A, increased the expressions of KCC2 and BDNF in the perilesional cortex and enhanced the synaptic plasticity in the denervated cervical spinal cord after cerebral ischemia. The behavioral performance of ischemic rats was significantly improved by bumetanide. In conclusion, bumetanide promoted post-stroke axonal sprouting together accompanied by an improved behavioral outcome possibly through restoring and maintaining neuronal chloride homeostasis and creating a recovery-promoting microenvironment by overcoming the axonal growth inhibition encountered after cerebral ischemia in rats.

Abstract
Objective: To evaluate the value of CT in the risk assessment of thyroid benign nodules (BN) and malignant nodules (MN). Methods: The CT signs of 461 pieces of MN in 447 cases and 548 pieces of BN in 484 cases were retrospectively analyzed, the diagnoses were confirmed by histology, including nodular morphology, cookie bite sign, microcalcification, enhanced range narrow/blurred, cystic changes and enhanced.The signs of CT were analyzed by univariate and multivariate regression analysis.The positive CT signs were calculated to assess sensitivity and specificity in the diagnosis of BN and MN. Results: Univariate and multivariate analysis showed that irregular nodular morphology (χ(2)=509.263, P<0.001, OR=5.297), cookie bite sign (χ(2)=504.619, P<0.001, OR=3.467), microcalcification (χ(2)=97.793, P<0.001, OR=1.730), enhanced range reduction/blur (χ(2)=361.967, P<0.001, OR=5.729) were more common in MN.Cysts changes (χ(2)=223.208, P<0.001, OR=7.537) and enhancement signs (χ(2)=65.983, P<0.001, OR=10.782) were more common in BN.The sensitivity and specificity of irregular nodular morphology in the diagnosis of MN were 80.5% and 90%, those in cookie bite sign were 74.2% and 94.3%, microcalcification were 35.6% and 90.1%, enhanced range reduction/blur were 80.7% and 79.4%.The sensitivity and specificity of capsule-based and high-enhanced BN diagnosis were 42.2% and 98.1%, 19.0% and 97.4%, respectively. Conclusions: Irregular shape, cookie bite sign, microcalcification and enhanced range of narrowing/blur are significant CT signs in the assessment of MN, and cystic changes and enhancement are significant CT signs in the evaluation of BN.The diagnostic efficiency of various CT signs varies greatly, and combination of multiple CT signs can improve the diagnostic efficiency.

Abstract
Objective: To explore the clinical efficacy of ladder neoadjuvant therapy in treatment of advanced mid-low rectal cancer. Methods: We performed a retrospective study of one hundred and eighty mid and low rectal cancer patients who underwent ladder neoadjuvant therapy(neoadjuvant chemotherapy followed by surgery if neoadjuvant chemotherapy was effective; neoadjuvant chemotherapy followed by neoadjuvant chemoradiotherapy if neoadjuvant chemotherapy was ineffective)(n=90) or neoadjuvant chemoradiotherapy (n=90). Results: In the ladder neoadjuvant therapy group, the descent stage rate was 85.6% (77/90), the anastomosis rate was 50.0% (45/90), the pre-sacral infection rate was 4.4% (4/90), the pathological complete remission (pCR) was 13.3%(12/90), R0 resection rate was 85.6% (77/90), the 2-year disease control rate was 76.7% (69/90), and the 2-year survival rate was 90.0% (81/90). In the control group, the descent stage rate was 88.9% (80/90), The anastomosis rate was 45.6% (41/90), the rate of pre-sacral infection was 11.1% (10/90), pCR was 16.7% 15/90), R0 resection rate was 88.9% (80/90), the 2-year disease control rate was 78.9% (71/90), and the 2-year survival rate was 87.8% (79/90). The difference was not statistically significant (P>0.05). The ladder neoadjuvant therapy group had lower prophylactic transverse colostomyrate(10.0% vs 34.4%), lower radiation injury rate (6.7% vs 27.8%), and lower sexual dysfunction rate (38.9% vs 87.8)compared to the control group. Conclusions: The ladder neoadjuvant therapy might reduce side injury caused by radiotherapy, improve compliance of patients, and reduce treatment costs. Moreover, the RO resection rate, 2-year local control rate and 2-year survival rate of ladder neoadjuvant therapy group was comparable with neoadjuvant chemoradiotherapy.

Abstract
We describe here innovative processing of low alloy medium-carbon steel with a duplex microstructure composed of nanoscale spheroidized cementite (Fe3C) in an ultrafine-grained (UFG) ferritic steel. After multi-pass rolling and intermittent annealing at 550 °C for 300 s, the obtained UFG-1 steel showed an average ferrite grain size of ~430 nm, containing nanoscale spheroidized cementite (Fe3C) particles with an average size of ~70 nm. On annealing at 600 °C for 300 s, the average size of ferritic grains was increased to ~680 nm and the average size of spheroidized Fe3C particles increased to ~90 nm, referred as UFG-2 steel. Tensile tests indicated that UFG-1 steel had high yield strength (σy) of 1260 MPa, and ultimate tensile strength (σUTS) of 1400 MPa. These values are higher than that of UFG-2 steel (σy = 1080 MPa and σUTS = 1200 MPa), suggesting that the strengthening contribution is a cumulative effect of decrease in ferrite grain size and nanoscale cementite. The incoherent interfaces between nanosized particles and the matrix acted as a strong barrier to dislocation motion. The study underscores that nanosized precipitates not only provide strength but also contribute to ductility, which is very encouraging for improving the ductility of medium-carbon steels.

Abstract
OBJECTIVE To explore the correlation between effect of PIO (pioglitazone, PIO) on learning as well as memory and ERK1/2 (extracellular signal regulated kinase 1/2, ERK1/2) pathway in T2DM (type 2 diabetes mellitus, T2DM) rats, further to elucidate the potential mechanism of PIO in improvement of learning and memory. METHODS 12-week-old male SD rats (number of 10 per group) were randomly divided into control group (CON), T2DM group (DM) and T2DM +PIO group (DM+PG). Rats in DM and DM+PG groups were given high fat diet for 20 weeks, then treated with Streptozotocin (27mg/kg) by intraperitoneal injection at 21week. After 72h, the FBG (fasting blood glucose, FBG) was greater than 7.0mmol/L can considered T2DM rats. DM+PG group was treated with PIO (10 mg·kg-1·d-1) by gavage daily. After Hyperinsulinemic-Euglycemic Clamp Study and Morris water maze test at 30-week, all of animals were sacrificed. The expressions of RKIP (Raf-1 kinase inhibitor protein, RKIP) and ERK1/2 in hippocampus were detected using Western Blot and real-time PCR. RESULTS The FBG level: DM group (7.68±0.54mmol/L) was higher than CON group (5.35±0.63mmol/L) and DM+PG group (6.07±0.84mmol/L), the differences were considered statistically significant (P <0.05). Hyperinsulinemic-Euglycemic Clamp Studies: GIR (glucose infusion rate, GIR) of DM group (21.02±5.10 mg·kg-1·d-1) was less than CON group (27.64±3.87 mg·kg-1·d-1) and DM+PG group (26.04 ±5.41 mg·kg-1·d-1), the differences were considered statistically significant (P <0.05). Morris water maze training: The escape latencies and searching platform performance of DM group (24.54±5.02s) decreased significantly compared with CON group (16.73±4.02s) and DM+PG group (18.05±4.12s) (P <0.05). Changes of RKIP, ERK, p-ERK protein relative content in rat hippocampus: Compared with CON groupand DM+PG group, the relative content of RKIP in DM group remarkably increased (P<0.01); ERK protein levels were not considered statistically significant among the three groups (P>0.05); The relative content of p-ERK1/2 protein in CON group and DM+PG group rats dorsal were higher than those in group DM, the difference was considered statistically significant (P<0.01). Changes in hippocampus of rat RKIP and ERK gene relative content: Compared with CON group and DM+PG group, levels of RKIP mRNA in DM group were significantly increased (P<0.01); ERK mRNA levels were not considered statistically significant among the three groups (P>0.05). CONCLUSION Activation of ERK1/2 signal transduction pathway via reducing RKIP in the hippocampus may be one of the mechanisms of PIO to improve the learning and memory of the T2DM rats.

Abstract
The prevention of chemotherapy‐induced nausea and vomiting was one of the most challenging supportive care issues in oncology, especially to highly emetogenic chemotherapy (HEC). A total of 645 patients were randomized into fosaprepitant group (fosaprepitant/placebo 150 mg d1 in combination with granisetron and dexamethasone) or aprepitant group (aprepitant/placebo 125 mg d1; 80 mg d2‐d3 plus granisetron and dexamethasone).The primary endpoint was the percentage of patients who had a complete response (CR) over the entire treatment course (0–120 hr, overall phase [OP]). It was assessed by using a non‐inferiority model, with a non‐inferiority margin of 10%. The difference of the CR rate was compared between two groups with chi‐square analysis. Six hundred and twenty‐six patients were included in the per protocol analysis. The percentage of patients with a CR in the fosaprepitant group was not inferior to that in the aprepitant group (90.85% versus 94.17%, p = .1302) during OP. Whether the cisplatin‐based chemotherapy or not, the CR rate of the fosaprepitant group was not inferior to that of the aprepitant group. Both regimens were well tolerated. The most common adverse event was constipation. Fosaprepitant provided effective and well‐tolerated control of nausea and vomiting associated with HEC in Chinese patients.

Abstract
OBJECTIVE To observe the influence of lumbar sympathetic ganglion radiofrequency thermocoagulation on the activation of spinal microglia in rats with diabetic neuropathic pain (DNP). METHODS Thirty-six painful diabetic Sprague-Dawley rats induced by 60 mg/kg streptozotocin (STZ) intraperitoneal injection were randomly divided into diabetic neuropathic pain group (group DNP, n=12), Sham operation group (group Sham, n=12) and radiofrequency thermocoagulation group (group R, n=12). Meanwhile another 12 age-matched rats were allocated as normal control group (group N), rats in group N received intraperitoneal injection of equal volume of normal saline. Twenty-eight days after STZ injection, rats in group R received L3 lumbar sympathetic ganglia radiofrequency thermocoagulation on the left side under X-ray guideline after anesthesia with damage time 60 s and damage temperature 60 ℃. Rats in group Sham received puncture positioning, but not thermocoagulation therapy. The mechanical paw withdrawal threshold (PWT) were performed before STZ injection, 7, 14, 21, 28 days after STZ injection and 1, 3, 5, 7, 14 days after radiofrequency thermocoagulation, respectively. Blood glucose were performed before STZ injection, 3, 28 days after STZ injection and 1, 14days after radiofrequency thermocoagulation. After the final behavioral testing, L3-L5 spinal cord tissues were removed to exam the expression of microglia marker OX42 by Western blotting and immunofluorescence technique, and the changes in the expression of inflammation factor IL-1β, IL-6, TNF-α were detected by ELISA technique. RESULTS Compared with group N, after 14, 21, 28 days of STZ injection and 1, 3, 5, 7, 14 days of radiofrequency thermocoagulation, the PWT of group DNP and group Sham decreased significantly (P<0.05); Before radiofrequency thermocoagulation, the PWT of rats in group DNP was (3.84±0.83) g, the PWT of rats in group R was (4.45±0.88) g, there was no statistically significant difference between group DNP and group R (t=1.514, P>0.05), but after radiofrequency thermocoagulation, compared with DNP group, the PWT of rats in group R increased significantly (P<0.05), and lasted to 14 d after radiofrequency thermocoagulation. The ratio of spinal microglia marker OX42 and GAPDH, the expression of inflammation factor IL-1β, IL-6, and TNF-α in group N were 0.074±0.023, (35.93±6.16) pg/ml, (92.11±13.23) pg/ml, and (169.50±22.64) pg/ml, respectively. The ratio of spinal microglia marker OX42 and GAPDH, the expression of inflammation factor IL-1β, IL-6, and TNF-α in group DNP were 1.023±0.185, (73.82±9.25) pg/ml, (155.33±21.82) pg/ml, and (298.30±33.21) pg/ml, respectively. The ratio of spinal microglia marker OX42 and GAPDH, the expression of inflammation factor IL-1β, IL-6, and TNF-α in group Sham were 0.951±0.103, (73.00±7.54) pg/ml, (151.02±24.26) pg/ml, and (294.01±36.37) pg/ml, respectively. The ratio of spinal microglia marker OX42 and GAPDH, the expression of inflammation factor IL-1β, IL-6, and TNF-α in group R were 0.563±0.019, (51.81±7.36) pg/ml, (123.24±16.13) pg/ml, and (229.23±29.16) pg/ml, respectively. Compared with group N, the expression of spinal microglia marker OX42 and inflammation factor IL-1β, IL-6, and TNF-α in group DNP, group Sham and group R increased significantly (F=7.501, 348.698, 568.021, 145.110, all P<0.05). Compared with DNP group, the expression of spinal microglia marker OX42 and inflammation factor IL-1β, IL-6, and TNF-α of group R reduced significantly (all P<0.05). CONCLUSION The lumbar sympathetic ganglion radiofrequency thermocoagulation can alleviate diabetic neuropathic pain. The mechanism may relate with the inhibition of spinal microglia activation and the lower expression of inflammation factor.

Abstract
Objective:To investigate the long-term efficacy and safety between induction chemotherapy and concurrent chemotherapy in patients with locally advanced nasopharyngeal carcinoma.Method:From January 2006 to January 2011, 190 patients with nasopharyngeal carcinoma were enrolled in the study. Among them, 92 patients received induction chemotherapy and radiotherapy who were classified as the study group, while 98 cases received concurrent radiotherapy and chemotherapy plus adjuvant chemotherapy who were classified as the control group. The general data, overall survival rate, progression free survival rate, acute and chronic adverse reactions were compared between the two groups, and the prognostic factors of local advanced nasopharyngeal carcinoma were analyzed.Result:The 5 year progression free survival (70.7%, 67.3%, P= 0.591) and overall survival (78.3%, 78.6%, P= 0.635) did not differ significantly between the two groups. There was no significant difference in recurrence or metastasis rate between the two groups (29.3%, 35.7%, P= 0.435). The incidence of grade Ⅲ-Ⅳ leukopenia and nausea and vomiting was significantly lower in the study group than that in the control group (P< 0.05), while there was no significant difference in the incidence of late adverse reactions between the two groups (P 0.05). Multivariate analysis showed that age (P= 0.000) and N stage (P= 0.003) were independent prognostic factors for overall survival in patients with locally advanced nasopharyngeal carcinoma.Conclusion:The effect of induction chemotherapy combined with radiotherapy and chemoradiotherapy plus adjuvant chemotherapy was equivalent to locally advanced nasopharyngeal carcinoma, however, the acute adverse reaction rate of induction chemotherapy+radiotherapy was lower. Therefore, induction chemotherapy+radiotherapy may be more effective and safe treatment for patients with local advanced nasopharyngeal carcinoma.

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
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
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.

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.
