Abstract
Objective: To observe the incidence and to determine the significance of laryngopharyngeal reflux (LPR) in laryngeal cancer and vocal leukoplakia. Methods: The patients who had been diagnosed as laryngeal cancer or vocal leukoplakia between January 2014 and June 2017 were included in this study. All of them received 24-hour multichannel intraluminal impedance-pH monitoring. The prevalence of LPR and numerous parameters from the 24-hour pH monitoring in laryngeal cancer patient and vocal leukoplakia patient groups were analyzed. The chi-square test was used for counting data, t test and Mann-Whitney U were used for measuring data. Results: In the 91 laryngeal cancer patients, the prevalence of pathologic LPR was 28.6%(26/91), the median number[P(25), P(75), P(95)]of acid reflux events was 0[0, 3, 5], time of acid exposure was 0[0, 14, 234]s, number of weakly acidic reflux events was 3[0, 6, 11]. In the 54 vocal leukoplakia patients, the prevalence of pathologic LPR was 29.6%(16/54), the number of acid reflux events was 0[0, 3, 4], time of acid exposure was 0[0, 13, 118]s, number of weakly acidic reflux events was 1.5[0, 5, 9]. The incidence of LPR did not vary in the laryngeal cancer patient and vocal leukoplakia patient groups, but were both higher than healthy Chinese volunteers according to a report in the other literature. Furthermore, all the three patients with no history of tobacco or alcohol existed acid or weakly acidic reflux episodes. Conclusions: Laryngopharyngeal reflux might play a role as an etiologic factor in laryngeal cancer and vocal leukoplakia.

Abstract
AbstractObjective:To review the demographic characteristics and canalith repositioning efficacy in 907 patients with typical benign paroxysmal positional vertigo(BPPV). Method: The demographic characteristics of 907 patients with typical BPPV were statistically analyzed. According to the type of BPPV, patients were treated with the appropriate repositioning maneuver, and the clinical efficacy of repositioning maneuver was analyzed and summarized. Result: Nine hundred and seven patients of BPPV with typical nystagmus were elected in this study. 585 out of 907 were female and 322 out of were male, and the mean age was 53.10±14.25(13 to 89) years. The lesion located to the posterior semiCIrcular canal was 489 patients(53.9%), horizontal semiCIrcular canal was 312 patients(34.4%), anterior semiCIrcular was 63 patients(6.9%), and multiple semiCIrcular was 43 patients(4.8%). According to Kaplan-Meier survival analysis curve, the median cure time for the modified Semont and Epley repositioning maneuver in PC-BPPV groups was 3 days, and there was no significant difference in survival curves between the two repositioning maneuver. Meanwhile, the median cure time for Barbecue and Li horizontal canal quick repositioning maneuver groups was 3 days, and 1 day for Gufoni repositioning maneuver group in HC-BPPV groups. And there was no significant difference in survival curves among the three repositioning maneuver. In the AC-BPPV, 7 cases, 31 cases, 57 cases, 58 cases were cured with the Li anterior canal quick repositioning maneuver in the 1st day, the 3rd day, 1 week later, and 1 month later, and 5 cases lost to be follow-up. According to Kaplan-Meier survival analysis curve, the median cure time for the Li anterior canal quick repositioning maneuver in AC-BPPV groups was 3 days. Conclusion:Repositioning maneuver represents a simple, safe, rapid and effective approach to the treatment of BPPV. Therefore, repositioning maneuver should be choice for the BPPV treatment.

Abstract
Objective: The consistency and characteristics of 24-hour multichannel intraluminal impedance(MII)-pH monitoring and Dx-pH monitoring in the diagnosis of laryngopharyngeal reflux were investigated. Methods: Fifty-two patients with laryngopharyngeal reflux related symptoms or disease between March and October 2017 were included in this study.All patients were evaluated with 24-hour MII-pH monitoring and Dx-pH monitoring at the same time, recording each patient's number of positive laryngopharyngeal reflux events, time of acid clearance and Ryan index.The data was analysed with Mann-Whitney U test and consistency check. Results: Among all 52 patients, 16 patients(30.7%) had a positive MII-pH monitoring result and 14 patients(26.9%) had a positive Dx-pH monitoring results.The consistency of both technique for measurement of laryngopharyngeal reflux was general(κ=0.626). With MII-pH monitoring for reference, the sensitivity and specificity of 24-hour pH monitoring were 68.8% and 91.7%.A total of 62 positive reflux events(pH<4) were measured with MII-pH monitoring, and 50 positive reflux events(upright pH<5.5 or supine pH<5.0)were detected by Dx-pH monitoring.There were 44 positive reflux events detected by both techniques, the mean time of acid clearance was 22.8[13.5; 42.6] s. Correspondingly, 18 reflux events were measured by MII-pH monitoring without positive results of Dx-pH monitoring, the mean time of acid clearance was 5.2[3.5; 6.5] s. There was significant difference in the time of acid clearance between two groups(U=858.5, P<0.05). Conclusions: Dx-pH monitoring can accurately measure the change of pH value in airway, but exists the possibility of misdiagnosis especially when the time of acid clearance in laryngopharynx is short. MII-pH and Dx-pH monitoring can be complementary technique in the diagnosis of laryngopharyngeal reflux.

Abstract
Objective:To provide evidence and strategy for treatment of very old patients with benign paroxysmal positional vertigo (v-BPPV) by retrospective analysis of v-BPPV patients. Method:According to the criteria, 19 v-BPPV patients were collected, aging from 80 to 91 years old, including 10 horizontal semicircular canal BPPV (HC-BPPV), 4 posterior semicircular canal (PC-BPPV) and 5 mutiple semicircular canal BPPV patients. PC-BPPV patients were treated by Epley or Li maneuver, and HC-BPPV patients were treated by Barbecue or Li maneuver. Each patient was treated twice, with an interval of 5 to 10 minutes. Result:Rates of 3-day cure and efficacy were 63.16% and 94.74%, respectively. Rates of 1-week cure and efficacy were 89.47% and 100.00%, respectively. Conclusion:v-BPPV can have good outcomes via proper treatment. Age should not influence BPPV outcomes, while we should pay more attention to v-BPPV patients' physiclal status and systematic diseases which may increase risk to diagnosis and treatment.

Abstract
Objective:To evaluate the efficacy and safety of regional neck dissection in the treatment of cN0 laryngeal carcinoma with positive cervical lymph node. Method:A retrospective analysis of 120 cases with cN0 laryngeal squamous cell carcinoma who received the first time for primary tumor resection and regional neck dissection (Ⅱ-Ⅳ) in our hospital during the period of 2000.01-2016.06 were performed. Twenty-two patients with lymph node positive (pN+) were selected by postoperative paraffin pathology in Ⅱ-Ⅳ region and followed up to 2017.06. The recurrence rate, survival rate and survival related regression analysis of patients with stage cN0 pN+ laryngeal carcinoma were analyzed. Result:The cN0 laryngeal cancer occult metastasis rate was 18.33% (22/120) in regional neck dissection. Local recurrence, regional recurrence, distant metastasis rates of 3 and 5 years were 41.18%, 17.65%, 17.65% and 40.00%, 13.33%, 20.00%, respectively in cN0 pN+ patients. The overall survival rates of 3 and 5 years were 61.2% and 30.6% respectively, and the disease-free survival rate was 31.8% and 22.7%. There was no significant difference in overall and disease-free survival between the T staging or clinical classification (P>0.05). Cox regression analysis showed that overall survival was related to age and local-regional (RR=11.421, P=0.001, RR=5.211, P=0.022). Logistic multivariate regression analysis showed that local-regional recurrence was not related to each factor (P>0.05). Conclusion:Local recurrence rate and mortality rate of cN0 pN+ laryngeal carcinoma are higher, survival rate is lower, however, neck recurrence rate is low.Therefore, Ⅱ-Ⅳ neck dissection is a safe and effective treatment for neck of cN0 pN+ laryngeal carcinoma.

Abstract
Based on the living times, native places and medical works of Xin'an TCM physicians described in the Xin an ming yi kao(Textual Research of Famous Physicians of Xin'an Region), the geographical distribution of ancient TCM physicians was analyzed by using Excel software. It is found that Xin'an medicine was originated from the Eastern Jin Dynasty and highly developed in the Qing Dynasty, and the number of its TCM physicians in the Ming and Qing Dynasties was large than the summation of those from the Eastern Jin Dynasty to the Ming Dynasty. In regard to the district, the distribution of Xin'an TCM physicians was characterized by more in the southeastern and less in the northwestern parts, forming a distribution area concentrated in the three counties of Shexian, Wuyuan and Xiuning. The reasons of such concentration of Xin'an TCM physicians are closely related to the economic growth, the influence of Neo-Confucianism and the density of population.

Abstract
Objective:To investigate the clinical significance and value of the sleep apnea monitoring management platform in the treatment of patients with obstructive sleep apnea hypopnea syndrome (OSAHS) by comparing with the traditional continuous positive airway pressure (CPAP) card reader mode.Method:A total of 48 severe adult OSAHS patients from Department of Otorhinolaryngology Head and Neck Surgery-Sleep Medical Center of the Third People's Hospital of Honghe during the period of Nov. 2015 to Aug. 2016 were collected in this prospective study. All of them were diagnosed by PSG and treated with nasal continuous positive airway pressure. They were randomly divided into group A (n=24) and group B (n=24). Group A and B were treated with the traditional CPAP card reader mode and the sleep apnea monitoring management platform respectively. During the follow-up, the compliance, mean blood oxygen saturation, titration pressure, Epworth sleepiness scale after 1, 3, 6 and 12 month treatment were compared between two groups. Ttest was used to analyze the difference. Statistical significance was set at P <0.05.Result:Statistical analysis showed that there were significant difference in the compliance of using CPAP, mean blood oxygen saturation and Epworth sleepiness scale score between the two groups (P < 0.05), but the titration pressure had no difference between the two groups (P>0.05).Conclusion:Compared the sleep apnea monitoring management platform with traditional CPAP card reader mode in the treatment of OSAHS patients, the former could solve the problems during the CPAP use in time, improve the compliance of using CPAP, and which could increase the efficacy of CPAP. Thus, the sleep apnea monitoring management platform is of more clinical value and deserve promotion.

Abstract
In recent 20 years, the rapid development of acute Stanford type A aortic dissection in China has been mainly due to three aspects: (1) the refined classification of aortic dissection based on Stanford classification, (2) right axillary artery canal and selective cerebral perfusion technology become basic cardiopulmonary bypass strategy for Stanford type A aortic dissection, and (3) total aortic arch replacement and descending aortic stent graft surgery (Sun's surgery) become the standard treatment of Stanford type A aortic dissection. However, there are still many problems in the diagnosis and treatment of aortic dissection in China, such as: (1) unstandardized, lack of comprehensive guidelines of aortic dissection, (2) immature, perioperative organ protection and intraoperative blood protection technology remains a big flaw, and (3) it takes a long time to get patient prepared for surgery. In conclusion, as to the issue of the management of acute Stanford type A aortic dissection, there will be a long way for Chinese doctors to go. Peers should pay more attention to this problem and take more efforts, so that the outcome of acute Stanford type A aortic dissection surgical patients can be improved.

Abstract
Objective: To evaluate the consistency between 24-hour pH monitoring, reflux symptom index(RSI) and reflux finding score(RFS) when using pH<4 or pH<5 as threshold for 24-hour pH monitoring in the diagnosis of laryngopharyngeal reflux. Methods: Patients who presented with suspicious laryngopharyngeal reflux between February 2014 and December 2015 were included in this study. pH<4 and pH<5 reflux episodes, RSI and RFS were collected. The consistency between 24-hour pH monitoring and scale results were analyzed when pH<4 or pH<5 as threshold respectively. The sensitivity and specificity of 24-hour pH monitoring were calculated separately. Results: Median number(M[P25, P75, P95]) of reflux events were 0 [0, 3.0, 5.5] when using pH<4 as pathological threshold and 0 [0, 4.0, and 8.5] using pH<5 as pathological threshold. Laryngopharyngeal reflux was determined in 34.5% patients depending on 24-hour pH monitoring when pH<4 was used as threshold, chi-square revealed medium consistency (κ=0.483) between pH monitoring and scale result. If pH<5 was used as threshold, 41.8% patients were detected with laryngopharyngeal reflux, and the consistency of pH monitoring and scale result was medium(κ=0.540). With RSI and RFS for reference, the sensitivity and specificity of 24-hour pH monitoring were 54.7% and 93.4% respectively when pH<4 was used as threshold. If pH<5 was used as threshold, the sensitivity and specificity of 24-hour pH monitoring were 65.6% and 91.3% respectively. Conclusions: Compared with pH<4 as pathological threshold, the consistency of pH monitoring and scale results was a little better using pH<5 as pathological threshold.

Abstract
Obstructive sleep apnea hypopnea syndrome(OSAHS) as a common frequentlyoccurring disease, it can cause repeated episodes of hypoxaemia and hypercapnia during sleep. With long period of hypoxaemia, obvious pathological changes and dysfunction emerged in heart,brain and lung then all kinds of clinical symptoms appear. Because of the middle ear and inner ear themselves anatomical characteristics and blood supply of regulating mechanism, they often has been damaged before the other important organ damage. As scholars have indepth study of the auditory system complications in patients with OSAHS, various influence of OSAHS on the middle ear,inner ear also gradually be known.This paper will review the effect of OSAHS on middle ear, inner ear and vestibule function, hope to have some application value for clinical work.

Abstract
Objective:To study the risk factors related to level Ⅵ lymph node metastasis in clinical N0 (cN0) papillary thyroid carcinoma (PTC). Method:A total of 107 cases with cN0 PTC treated in the same group were analyzed retrospectively. The frequency and risk factors for level Ⅵ lymph node metastasis in these patients were analyzed. Result:Level Ⅵ lymph node metastasis existed in 51.40% (55/107) cases. In univariate analysis, level Ⅵ lymph node metastasis was associated with age (χ²=9.090,P<0.01), gender (χ²=5.061,P<0.05), tumor maximum diameter (χ²=8.772,P<0.01), tumor multifocality (χ²=8.120,P<0.01), capsular invasion (χ²=4.960,P<0.05), and surrounding tissue invasion (χ²=3.858,P<0.05), but not with nodular goiter or Hashimoto's thyroiditis. Multivariate logistic analysis indicated that age,tumor maximum diameter, multifocal tumors and surrounding tissue invasion were independent risk factors for level Ⅵ lymph node metastasis. Conclusion:A high risk level Ⅵ lymph node metastasis exists in DTC with clinical N0. Prophylactic level Ⅵ neck dissection is strongly recommended in patients with PTC who are younger, tumor size more than 2 cm, multifocal tumor and surrounding tissue invasion.

Abstract
The expression of glucocorticoid receptor-α and -β (GR-α and GR-β) in the tonsil tissues of children with and without obstructive sleep apnea hypopnea syndrome (OSAHS) was evaluated. A total of 30 children with OSAHS who underwent tonsillectomy in the Navy General Hospital from June 2012 to June 2014 were enrolled as the experimental group, and 30 non-OSAHS children were enrolled as the control group. The diagnosis of OSAHS was confirmed by preoperative sleep monitoring. The expression of GR-α and GR-β in tonsil tissues was detected using western blot and immunohistochemical analyses. GR-α and GR-β were both expressed in the tonsil tissues of OSAHS and non-OSAHS patients. The expression of GR-α in the tonsil tissues of OSAHS children was significantly lower than that in the tonsil tissues of non-OSAHS children, while the expression of GR-β in the tonsil tissues was similar between the two groups of children. Since it has been reported that GR-α expression is correlated to glucocorticoid therapy sensitivity, the sensitivity of children with OSAHS to glucocorticoid treatment may be lower than that in children who do not have OSAHS. However, the function of GR in children with OSAHS still requires further investigation.

Abstract
We investigated the expression characteristics of matrix metalloproteinases (MMP)-2 and MMP-9 in the ovaries of normal adult guinea pigs during the estrous cycle. The estrous cycle was classified according to the appearance of the vaginal orifice and by vaginal exfoliated cell smears. Guinea pigs that had experienced at least two normal estrous cycles were selected. Ovaries were collected from guinea pigs at proestrus or metestrus (N = 6). The expression characteristics of steroidogenic acute regulatory protein (StAR), MMP-2, and MMP-9 were investigated by hematoxylin and eosin staining and immunohistochemical staining. The results showed that MMP-2, MMP-9, and StAR were significantly expressed in the granulosa and thecal cells of the ovarian atretic follicles during proestrus, and were strongly expressed in the corpus luteum during metestrus.

Abstract
Guanosine 3',5'-cyclic monophosphate (cGMP), as a second messenger, plays potential roles in ovarian functions. To elucidate the role of phosphodiesterase (PDE) in cGMP signaling during ovarian follicular development, the present study was conducted to investigate ovarian cGMP level and cGMP-PDE activity by radioimmunoassay (RIA) in postnatal rats, immature rats during gonadotropin-primed follicular development, ovulation and luteinization, adult rats during normal estrous cycle, and aged rats that spontaneously developed persistent estrus (PE). All four rat models were confirmed by histological examination of one ovary, and the other ovary was used for RIA. In postnatal rats, cGMP level was high at birth and decreased dramatically by Day 5, and then, it increased maximally at Day 10 and declined at Day 21. However, cGMP-PDE activity did not significantly change during Days 1 to 10, but increased significantly on Day 21. In immature female rats, cGMP level markedly decreased upon treatment with equine chorionic gonadotropin (eCG), while cGMP-PDE activity did not show any significant changes; however, ovarian cGMP level and cGMP-PDE activity increased after injection of an ovulatory dose of human chorionic gonadotropin (hCG) for induction of ovulation and luteinization. In adult rats during normal estrous cycle, cGMP level was high on proestrus and metestrus days, while cGMP-PDE activity was high on estrus day. In PE rats, ovarian cGMP level was similar to that in adult rats on estrus and diestrus days but lower than that on proestrus and metestrus days; ovarian cGMP-PDE activity was lower than that on estrus days but similar as the other estrous cycle days. In addition, there was a significant negative correlation between ovarian cGMP level and cGMP-PDE activity during normal estrous cycles in the adult rat (r = -0.7715, N = 16, P < 0.05), but not in the postnatal rat (r = -0.1055, N = 20, P > 0.05). Together, the results of our present study indicated that ovarian cGMP levels were not dependent on cGMP-PDE activity during early postnatal development, but highly dependent on cGMP-PDE activity in the adult rat. This implies that mechanisms of cGMP signaling involved in ovarian functions are stage-specific in the rat.

Abstract
A series of Polyurethane/Chitosan composite foam with different chitosan content of 5–25 wt% was prepared, and their adsorption performance of malachite green (MG) in aqueous solutions was investigated by pH values, contact time, temperatures and chitosan content. It was observed that Polyurethane/Chitosan composite foam exhibited well-developed open cell structures. Malachite green adsorption capacities of the composite foam increased with the increment of chitosan content in composite foam. Polyurethane/Chitosan composite foam with 20% chitosan content exhibited a maximum removal capacity of 16.67 mg/g and 95.60% MG removal efficiency. In addition, MG adsorption capacities of composite foam increased with pH value increase, 30℃ was the optimum temperature, which affects the adsorption process, and the adsorption maximum was attained within 12 hours. The result of SEM showed the prepared composite foam possess well-developed open cell structures. The MG adsorption kinetics and equilibrium isotherm of the composite foam were well described with the pseudo-second order kinetic model and Langmuir isotherm model, respectively. This work provided an attractive adsorbent for removing of the hazardous materials from water.

Abstract
This study compared the accumulation of Zn²⁺ and Cu²⁺ in the ovaries and ova of loaches under different concentrations of Zn²⁺ (1.00, 2.50 and 5.00 mg/L respectively) and Cu²⁺ (0.10, 0.25 and 0.50 mg/L respectively). The results showed that both Zn²⁺ and Cu²⁺ accumulated in the ovaries, and that the relationship between accumulation and time was linear over 20 days of exposure. The accumulation of the metals in ovaries was closely related to the concentration of exposure in the solutions (P<0.05), and was obviously affected by the time and doses. However, the Cu²⁺ concentration was significantly higher than Zn²⁺ (P<0.05). The development level of ova in the ovaries also correlated with the concentration and exposure period in the Zn²⁺ and Cu²⁺ solutions. This study compared the accumulation of Zn2+and Cu2+ in the ovaries and ova of loaches under different concentrations of Zn2+ (1.00, 2.50 and 5.00 mg/L respectively) and Cu2+ (0.10, 0.25 and 0.50 mg/L respectively). The results showed that both Zn2+ and Cu2+ accumulated in the ovaries, and that the relationship between accumulation and time was linear over 20 days of exposure. The accumulation of the metals in ovaries was closely related to the concentration of exposure in the solutions (P<0.05), and was obviously affected by the time and doses. However, the Cu2+ concentration was significantly higher than Zn2+(P<0.05). The development level of ova in the ovaries also correlated with the concentration and exposure period in the Zn2+ and Cu2+ solutions.

Abstract
Wheat-Dasypyrum villosum translocated chromosomes T6V#2S•6AL and T6V#4S•6DL are known to confer excellent resistance to wheat powdery mildew (PM). However, it is difficult to distinguish the two sources of PM resistance genes through multi-pathotype testing because to date no virulence for them has been found. To reveal the relationship between the PM resistance genes from the two translocations, the sequence of the Stpk-V gene, a key member of powdery mildew resistance locus Pm21, was used as a reference to isolate homologous genes from a D. villosum accession No.1026 and its derivatives 6V#4(6D) disomic substitution (DS) line RW15 and T6V#4S•6DL translocation line Pm97033. Two genes Stpk-V2 and Stpk-V3 were cloned from No.1026. Sequence alignment showed that Stpk-V2 and Stpk-V3 shared 98.2 % and 96.2 % of their DNA and 99.3 % and 100 % of their amino acids in identity with Stpk-V. Compared with Stpk-V, a 22-bp direct sequence repeat and a miniature inverted-repeat transposable element (MITE) were found in the intron 4 of Stpk-V2 and Stpk-V3, respectively. However, Stpk-V2 was not present in DS line RW15 and translocation line Pm97033 based on the PCR result, indicating that Stpk-V2 did not contribute to the PM resistance of RW15 and Pm97033. In the promoter region, a 78-bp insertion was found not only in Stpk-V2 and Stpk-V3, but also in its orthologous gene Stpk-A of wheat. In addition, there was a 17 bp/8 bp deletion/insertion in the putative promoter of Stpk-V3 in comparison with that of Stpk-V/Stpk-V2. Real-time quantitative RT-PCR analysis indicated that the expression levels of Stpk-V and Stpk-V3 genes in the translocation lines were induced by the pathogen, but Stpk-V had a higher expression level than Stpk-V3 at 12 h after inoculation with Bgt. The diversity of Stpk-V gene will help to explore new resistance genes to PM in D. villosum for wheat breeding.

Abstract
OBJECTIVES This study was to explore the independent influence of menopause on cardiovascular disease (CVD) and its risk factors in rural Chinese females. STUDY DESIGN This cross-sectional population-based study enrolled 2245 premenopausal and 2498 postmenopausal women aged 40-59 years in Fangshan district, Beijing, China. Data was collected by face-to-face interview, physical examination and biochemical examination during 2009 and 2010. General liner models were employed to calculate age-adjusted means of cardiovascular risk factors (CRFs). The comparisons of CVD and it risk factors according to menopausal status, and calculation of adjusted odds ratios/coefficients and their 95% confidence intervals for the associations of quartiles of elapsed time since menopause and age at menopause with CVD and its risk factors was performed by multivariate logistic/liner regression models separately. RESULTS After adjustment for age and other confounders, no statistically significant association of menopause with CVD was observed in our participants; however, dyslipidemia prevalence and levels of waist-to-hip ratio, triglycerides, total cholesterol and low-density lipoprotein cholesterol were presented higher in postmenopausal group, compared to the premenopausal one (P<0.05). Compared to women who had been menopausal for less than1 year, those with the elapsed time since menopause of 2-3 years had higher CHD prevalence, higher triglycerides level and lower high-density lipoprotein cholesterol level (P<0.05). CONCLUSIONS Postmenopausal women in rural China had worse CRFs profile than the premenopausal ones, which implied menopause might aggravate the CRFs epidemic beyond effects of aging, and would increase the CVD burden during and after their middle ages.
