Abstract
Cleft palate is one of the most common maxillofacial birth defects, which can occur alone or accompany with many known deformities. Palatal selves need to complete the process of vertical growth, elevation, adhesion and fusion in a specific time window of embryo development. Any abnormality in this process will lead to cleft palate. Although previous studies have identified many molecular networks that regulate the growth, location and fusion of palatal selves, there are still many unknown mechanisms for palatal development. The pathogenesis of cleft palate has not been clarified so far. In recent years, the molecular research on palate development has been deepened continuously. Here we summarize major recent advances and integrate the genes and molecular pathways with the cellular and morphogenetic processes of palatal shelf growth, patterning, elevation, adhesion, and fusion, in order to comprehensively understand the genotype-phenotype functional relationship and provide assistance in formulating effective prevention strategies for cleft palate disease.

Abstract
Objective: To explore the safety and reliability of retrosigmoid approach BONEBRIDGE implantation in patients with auricle reconstruction using skin expansion flap. Methods: A retrospective analysis was conducted on 43 congenital aural atresia cases (43 ears) who underwent BONEBRIDGE implantation from September 2019 to January 2023 in Beijing Tongren Hospital. 30 males and 13 females were included in this work. The implantation age was 9-36 years old (median age=10 y/o). All cases underwent auricle reconstruction surgery using the posterior ear flap expansion method, with 36 cases using the single expanded postauricular flap method and 7 cases using two-flap method. BONEBRIDGE implant surgery was performed during the third stage of auricle reconstruction or after all stages. The hearing improvements were evaluated by comparing the changes in pure tone hearing threshold and speech recognition rate of patients before and after BONEBRIDGE implantation. Routine follow-up was conducted to observe the hearing results and complications. SPSS 14.0 software was applied for data statistical analysis. Results: All 43 patients healed well and had no surgical complications when discharge. The average bone conduction hearing threshold after surgery was (8.2±6.6) dBHL, and there was no statistically significant difference compared to the preoperative [(8.1±5.7) dBHL] (P=0.95). After surgery, the threshold of hearing assistance with power on was significantly lower than that without hearing assistance [(32.8±4.6) dBHL vs (60.5±5.5) dBHL], and the difference was statistically significant (P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased to 72%, 84%, and 98% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words, and short sentences in noise environment was significantly increased by 70%, 80%, and 92% respectively (P<0.001). After a follow-up of 4 to 47 months (median=24 months), the hearing results were stable and the aesthetic outcomes were satisfying. One patient had delayed hematoma around coil of the implant. After aspiration and compressed dressing for one week, hematoma was not recurrent. Conclusion: For patients after auricle reconstruction using expanded postauricular flap, the preference of retrosigmoid approach is a good choice in terms of safety and reliability of operation, as well as aesthetic appearance.

Hyperbaric oxygen ameliorates neuronal injury and neurological function recovery in rats with intracerebral hemorrhage by silencing microRNA-204-5p-targeted chloride channel protein 3. JOURNAL OF PHYSIOLOGY AND PHARMACOLOGY : AN OFFICIAL JOURNAL OF THE POLISH PHYSIOLOGICAL SOCIETY 2023; 74. [PMID: 37661186 DOI: 10.26402/jpp.2023.3.09] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Received: 03/03/2023] [Accepted: 06/30/2023] [Indexed: 09/05/2023]
Abstract
Hyperbaric oxygen (HBO) therapy is of clinical utility in patients with transient cerebral ischemia. The investigatory study was to identify the potential regulatory mechanism of HBO treatment on neuronal injury and neurological function recovery in rats with intracerebral hemorrhage (ICH). Firstly, the rat model of ICH was established by collagenase, and the experimental rats were treated with HBO at 2.5 absolute atmospheres for 60 min each time. Next, lentivirus interfering with microRNA (miR)-204-5p or chloride channel protein 3 (CLCN3) expression was injected via the tail vein. Afterward, neurological function assessment was conducted, serum S100β and NSE contents were detected by enzymer-linked immunosorbent assay, and pathological conditions of brain tissue were observed by hematoxylin-eosin staining. Terminal deoxynucleotidyl transferase mediated dUTP nick end labeling staining was used to detect neuronal apoptosis. The results showed that HBO alleviated neuronal injury and neurological function recovery in ICH rats and reduced serum S100β and NSE content (all P<0.05). At the same time, overexpressing miR-204-5p or depleting CLCN3 further promoted the therapeutic effect of HBO on ICH rats (all P<0.05), while silencing miR-204-5p or elevating CLCN3 did oppositely (all P<0.05). In conclusion, HBO alleviates neuronal injury and neurological function recovery in ICH rats by silencing miR-204-5p-targeted CLCN3.

Controllable reduction of NiCoO 2@NiCo core-shell nanospheres on CNTs for high-performance electrochemical energy storage. J Colloid Interface Sci 2023; 645:154-164. [PMID: 37148681 DOI: 10.1016/j.jcis.2023.04.134] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/14/2023] [Revised: 04/13/2023] [Accepted: 04/24/2023] [Indexed: 05/08/2023]
Abstract
The performances of energy storage devices are strongly dependent on the electrode materials. Owing to the high theoretical capacity, NiCoO2 is a promising transition metal oxide for supercapacitors. Despite many efforts have been devoted, it still lacks of effective methods to overcome its shortcomings such as low conductivity and poor stability, in order to achieve its theoretical capacity. Herein, utilizing the thermal reducibility of trisodium citrate and its hydrolyzate, a series of NiCoO2@NiCo/CNT ternary composites in which NiCoO2@NiCo core-shell nanospheres deposited on CNT surface with adjustable metal contents are synthesized. Benefiting from the enhanced synergistic effect of both metallic core and CNTs, the optimized composite exhibits an extremely high specific capacitance (2660 F g-1 at 1 A g-1, the effective specific capacitance of the loaded metal oxide is 4199 F g-1, close to the theoretical value), an excellent rate performance and stability, when the metal content is about 37%. After depolarized calculation, the energy storage mechanism of the composite is reasonably analyzed. By controlling the contents of hexamethylenetetramine, trisodium citrate and CNTs in the reactant, the roles of them are distinguished. This study reveals an efficient novel strategy for transition metal oxides to maximize the electrochemical performances.

Abstract
Objective: Our study aims to determine histological regression and clinical improvement after long-term antiviral therapy in hepatitis B virus-related cirrhosis patients. Methods: Treatment-naïve chronic hepatitis B patients with histologically or clinically diagnosed liver cirrhosis were enrolled. Liver biopsies were performed after 5 years entecavir-based antiviral treatment. Patients were followed up every 6 months. Cirrhosis regression was evaluated based on Metavir system and P-I-R score. Clinical improvement was evaluated before and after the long-term treatment. Kruskal Wallis test and Wilcoxon signed-rank test were used for continuous variables, Fisher's exact test was used for categorical variables and multivariate analysis was performed using logistic regression analysis. Results: Totals of 73 patients with HBV-related liver cirrhosis were enrolled. Among them, 30 (41.1%) patients were biopsy proved liver cirrhosis and the remaining 43 (58.9%) cirrhotic patients were diagnosed by clinical features. Based on Metavir system and P-I-R score, 72.6% (53/73) patients attained histological regression. Furthermore, 30.1% (22/73) were defined as significant regression (Metavir decrease ≥2 stage), 42.5% (31/73) were mild regression (Metavir decrease 1 stage or predominantly regressive by P-I-R system if still cirrhosis after treatment) and 27.4% (20/73) were the non-regression. Compared to levels of clinical characteristics at baseline, HBV DNA, ALT, AST, liver stiffness(decreased from 12.7 to 6.4 kPa in significant regression, from 18.1 to 7.3 kPa in mild regression and from 21.4 to 11.2 kPa in non-regression)and Ishak-HAI score significantly decreased after 5 years of anti-HBV treatment, while serum levels of platelets and albumin improved remarkably (P<0.05). In multivariate analysis, only the pre-treatment liver stiffness level was associated with significant regression (OR=0.887, 95%CI: 0.802-0.981, P=0.020). Conclusions: After long-term antiviral therapy, patients with HBV-related cirrhosis are easily to attain improvements in clinical parameters, while a certain percentage of these patients still cannot achieve histological reversal.

Abstract
Objective: To clarify the effect and related factors of antiviral therapy on the change of esophageal varices in patients with hepatitis B virus-related cirrhosis. Methods: Fifty-two cases with hepatitis B virus-related cirrhosis who underwent endoscopy before and after antiviral therapy were selected from prospective cohorts. Patients were divided into three groups: no, mild, and moderate-severe based on the degree of esophageal varices. The changes in the severity of esophageal varices in each group were compared after antiviral therapy. Clinical characteristics (platelet, liver and kidney function, liver stiffness, and virological response) of patients with different regressions were analyzed. Measurement data were analyzed by independent sample t-test, one-way ANOVA, Mann-Whitney U test and Kruskal-Wallis H test, and Chi-Square test was used for count data. Results: All patients received entecavir-based antiviral therapy. The median treatment time was 3.1 (2.5-4.4) years. The proportion of patients without esophageal varices increased from 30.8% to 51.9%, the proportion of mild esophageal varices decreased from 40.4% to 30.8%, and the proportion of patients with moderate-to-severe esophageal varices decreased from 28.8% to 17.3% (χ2=14.067, P=0.001). A total of 40.4% of patients had esophageal varices regression, and 13.5% had esophageal varices progression. The progression rate was significantly higher in patients with moderate-severe esophageal varices than patients with mild and no esophageal varices (χ2=28.126, P<0.001), and 60.0% of patients with moderate-severe esophageal varices still remained in moderate-severe state after antiviral treatment. Baseline platelet count and 5-year mean change rates were significantly lower in patients with progressive moderate-to-severe esophageal varices than in those without progression (+3.3% vs. +34.1%, Z=7.00, P=0.027). Conclusion: After effective antiviral treatment, 40.4% of patients with hepatitis B virus-related cirrhosis combined with esophageal varices has obtained esophageal varices regression, but those with moderate to severe esophageal varices still have a considerable risk of progression while receiving mono antiviral treatment only. Thrombocytopenia and without significant improving are the clinical signs of progression risk after receiving antiviral treatment.

Abstract
Objective: To investigate the feasibility and safety of auricle reconstruction combined with Bonebridge implantation for bilateral aural atresia patients. Methods: A retrospective analysis was conducted for 36 cases(72 ears) who underwent Bonebridge implantation combined with bilateral auricle reconstruction from February 1, 2017 to January 15, 2020. All cases were bilateral congenital aural atresia and underwent Nagata auricle reconstruction for both sides simultaneously. Bonebridge implantations were performed during the second stage of auricle reconstruction. Results: All 36 patients healed well and had no surgical complications when discharged. The preoperative average bone conduction threshold of the patients was(8.5±5.8) dB HL and postoperative bone conduction threshold was (8.4±5.2) dB HL. There was no significant change after the implantation (P=0.724). The preoperative average air conduction threshold of was(64.9±7.4)dB HL and postoperative air conduction threshold was (24.0±5.3) dB HL, which had a significant change after the implantation (P<0.001). The hearing threshold with Bonebridge significantly decreased by 40.9 dB HL compared with the preoperative air conduction threshold(P<0.001). The speech recognition rate of monosyllable words, disyllabic words and short sentences in quiet environment increased by 62.5%, 63.5% and 72.2% respectively. The differences were statistically significant (P<0.001). The speech recognition rate of monosyllabic words, disyllabic words and short sentences in noise environment were significantly increased by 55.9%, 58.9% and 69.9% respectively (P<0.001). After a follow-up of 18.3 months in average, the hearing results were stable and the aesthetic outcomes were satisfied. One patient had implant rupture and healed after revision surgery. Conclusions: With an integrated surgical procedure, patients with bilateral congenital aural atresia can complete bilateral auricle reconstruction and hearing implantation within six months. This integrated surgical procedure is safe and efficient, with a stable hearing improvement and good appearance.

Abstract
Objective: To study the effects on learning and memory, mitochondrial energy metabolism and ATPase activity of hippocampus in mice with subacute exposure to n-hexane. Methods: The SPF 40 Kunming mice were randomly divided into low, middle and high dose groups and control groups according to different dosages. Each group consisted of 10 mice. The mice were given n-hexane by gavage, the mice in the low, middle and high dose groups were given 0.2 ml/d of n-hexane at concentrations of 500, 1000 and 2000 mg/kg respectively, while the mice in the control group were given 0.2 ml/d of cooking oil once a day for 28 days. The y-type maze test, the activity of ATP Enzyme, mitochondrial respiratory chain enzyme complex Ⅰ-IV, the mrna of mitochondrial fusion gene (MFn1, Mfn2) and fission gene (FIs1) in brain tissues were performed. Results: Except for the wrong reaction times of low-dose exposure group in the first test, there existed significantly different in the first and second Y-maze tests in exposure groups and control group (P<0.05) ; in low, middle and high-dose group, the Na(+)-K(+)-ATPase activities were (8.27±2.65) , (5.38±1.55) , (3.55±1.69) μmol/gprot/h, and Ca(2+)-Mg(2+)-ATPase activities were (10.32±2.96) , (7.19±1.94) and (4.49±1.33) μmol/gprot/h, respectively. Compared with those in control group, the activities of Na(+)-K(+)-ATPase and Ca(2+)-Mg(2+)-ATPase decreased significantly in middle-dose group and high-dose group (P<0.05) . Compared with those in control group, the activities of mitochondrial respiratory chain enzyme complex I-IV in each dose group were significantly decreased (P<0.05) . The expressions of Mfn1mRNA and Mfn2mRNA in each dose group was significantly lower than those in control group (P<0.05) . Conclusion: Subacute exposure to n-hexane can result in the decrease of activities of mitochondrial respiratory chain enzyme complex in hippocampus of mice, which may lead to the disorder of mitochondrial energy metabolism by the decrease of ATPase activity and the imbalance of mitochondrial fusion-division, which must be one of the mechanisms of impairment of learning and memory of mice induced by n-hexane.

Abstract
OBJECTIVE To explore the cytidine-phosphate-guanosine (CPG) sites associated with fas-ting plasma glucose (FPG) and glycated haemoglobin (HbA1c) in twins. METHODS In the study, 169 pairs of monozygotic twins were recruited in Qingdao, Zhejiang, Jiangsu, Sichuan and Heilongjiang in June to December of 2013 and June 2017 to October 2018. The methylation was detected by Illumina Infinium HumanMethylation450 BeadChip and Illumina Infinium MethylationEPIC BeadChip. According to the Linear Mixed Effect model (LME model), fasting plasma glucose and HbA1c were taken as the main effects, the methylation level (β value) was taken as the dependent variable, continuous variables, such as age, body mass index (BMI), blood pressure, components of blood cells, surrogate variables generated by SVA, and categorical variables, such as gender, smoking and drinking status, hypoglycemic drugs taking, were included in the fixed effect model as covariates, and the identity numbers (ID) of the twins was included in the random effect model. The intercept was set as a random. Regression analysis was carried out to find out the CpG sites related to fasting blood glucose or HbA1c, respectively. RESULTS In this study, 338 monozygotic twins (169 pairs) were included, with 412 459 CpG loci. Among them, 114 pairs were male, and 55 pairs were female, with an average age of (48.2±11.9) years. After adjustment of age, gender, BMI, blood pressure, smoking, drinking, blood cell composition, and other covariates, and multiple comparison test, 7 CpG sites (cg19693031, cg01538969, cg08501915, cg04816311, ch.8.1820050F, cg06721411, cg26608667) were found related to fasting blood glucose, 3 of which (cg08501915, ch.8.1820050f, cg26608667) were the newly found sites in this study; whereas 10 CpG sites (cg19693031, cg04816311, cg01538969, cg01339781, cg01676795, cg24667115, cg09029192, cg20697417, ch.4.1528651F, cg16097041) were found related to HbA1c, and 4 of which(cg01339781, cg24667115, cg20697417, and ch.4.1528651f) were new. We found that cg19693031 in TXNIP gene was the lowest P-value site in the association analysis between DNA methylation and fas-ting plasma glucose and HbA1c (PFPG=2.42×10-19, FDRFPG<0.001; PHbA1c=1.72×10-19, FDRHbA1c<0.001). CONCLUSION In this twin study, we found new CpG sites related to fasting blood glucose and HbA1c, and provided some clues that partly revealed the potential mechanism of blood glucose metabolism in terms of DNA methylation, but it needed further verification in external larger samples.

Abstract
The composites of NiCo2O4 with unique structures are extensively explored as promising electrodes. In this work, core-shell structured nanowires anchored on nickel foam are synthesized by the hydrothermal synthesis of NiCo2O4 as core and subsequent electrodeposition of α-Co(OH)2 as shell. The core-shell composites exhibit enhanced electrochemical performances ascribing to the synergistic reactions from both materials, showing higher specific capacitance than any single component. By changing the deposition time, the mass loading of α-Co(OH)2 can be easily controlled. The electrochemical performances of the hybrid electrodes are diverse with the mass loading of Co(OH)2. The optimized hybrid electrode with 3 mins electrodeposition exhibits the highest specific capacitance (1298 F g-1 at 1 A g-1) among all electrodes. The redox reaction is a main contributor to the total specific capacitance through electrochemical kinetics analysis. An asymmetric supercapacitor assembled by the optimized material as positive electrode and activated carbon as negative electrode can achieve a relatively high energy density of 39.7 Wh kg-1 at a power density of 387.5 W kg-1 (at 0.5 A g-1) in a voltage of 1.55 V.

Abstract
Objective: Meta-analysis was used to compare the long-term efficacy and laryngeal function preservation rate of patients with advanced hypopharyngeal cancer treated with surgery plus radio(chemo)therapy (SRT) or non-surgery chemoradiotherapy (CRT). Methods: We searched publicly published articles on case-control studies of surgical and non-surgical comprehensive treatment of advanced hypopharyngeal cancer in PubMed, the Cochrane Library, Wanfang Database, Chinese Journal Full-text Database, and Chinese Science and Technology Periodical Database. The search language was limited to Chinese and English, and the period was from 1990 to 2018. These literatures were rigorously screened by inclusion and exclusion criteria. The data needed for this study were extracted and the Meta analysis was performed using RevMan 5.3 software. Results: A total of 13 literatures were included, and the overall quality of the literature was relatively high, and no significant publication bias was suggested. A total of 1 994 subjects, including 720 in the SRT group and 1 274 in the CRT group. The average 3-year overall survival rates were 42.9% in SRT group and 44.8% in CRT group,with no significant difference (OR=1.14, 95%CI: 0.62-2.06, P=0.68). The average 5-year overall survival rate (OR=1.42, 95%CI: 1.10-1.84, P<0.01), 5-year local recurrence-free survival rate (OR=1.68, 95%CI: 1.11-2.55, P=0.01) and 5-year local control rate (OR=2.17, 95%CI: 1.52-3.12, P<0.01) of SRT group were 46.4%, 47.4% and 71.2%, respectively, which were higher than those of non-surgical group (37.9%, 32.0%, and 52.2% respectively). The average laryngeal function preservation rate was 19.8%,being significantly lower than 80.6% of the non-surgical group(OR=0.03, 95%CI: 0.01-0.07, P<0.01). Conclusions: SRT has better long-term efficacy, while CRT has better preservation of laryngeal function.

Abstract
Liver cirrhosis is the end stage of chronic liver disease and as the disease progresses to decompensated stage cirrhosis, the mortality rate of patients' increases significantly. The goal of controlling the etiology or treatment in decompensated stage cirrhosis is to improve the liver function of patients, stabilize the disease condition or reverse decompensation, reduce the recurrence of decompensated events and reduce the mortality rate. However, presently, there are few studies on the reversal of cirrhotic decompensation/ re-compensation. Moreover, the effect of prophylactic treatment on re-compensation, evaluation indicators and duration of re-compensation, structure of hepatic lobules and whether microvessels can be reconstructed are unclear, so require further research.

Abstract
CONTEXT Calenduloside E (CE), one of the primary natural products found in Aralia elata (Miq.) Seem. (Araliaceae), possesses prominent anti-apoptotic potential. A previous study found that one of the anti-apoptotic CE targets is heat shock protein 90 AB1 (Hsp90AB1) by probe CE-P, while the other targets of CE still need to be identified with more efficient probes. OBJECTIVE This study investigates CE analogue (CEA) as one clickable activity-based probe for use in exploring anti-apoptotic CE targets. MATERIALS AND METHODS Pretreatment of HUVECs with CEA (1.25 μM) for 8 hr, followed by ox-LDL stimulation for 24 h. Flow cytometry analysis and JC-1 staining assays were performed The kinetic constant measurements were tested by the Biacore T200, CM5 Sensor Chip which was activated by using sulpho-NHS/EDC. Ligands were dissolved and injected with a concentration of 12.5, 6.25, 3.125, 1.56, 0.78 and 0 μM. RESULTS CEA was confirmed to possess an anti-apoptotic effect. The probable targets of CE/CEA were calculated, and as one of the higher scores proteins (Fit values: 0.88/0.86), Hsp90 properly got our attention. Molecular modelling study showed that both CE and CEA could bind to Hsp90 with the similar interaction, and the docking scores (S value) were -7.61 and -7.33. SPR assay provided more evidence to prove that CEA can interact with Hsp90 with the KD value 11.7 µM. DISCUSSION AND CONCLUSIONS Our results suggest that clickable probe CEA could alleviate ox-LDL induced apoptosis by a similar mechanism of anti-apoptotic CE, and afforded the possibility of identifying additional anti-apoptotic targets of CE.

Abstract
Summary Allergic rhinitis(AR), a common and frequente disease, has attracted global attention in recent years. The imbalance between Th1 and Th2 cellular immune responses is the immunological basis of AR. Studies have found that vitamin D plays an important role in the occurrence of AR, and IL-33/ST2 is a newly discovered cytokine and signaling pathway in AR. There are certain specific associations between vitamin D and IL-33/ST2 in the pathogenesis of AR. This paper mainly analyzes the studies on the expression of vitamin D, IL-33/ST2 and Th1/Th2 cytokines in AR, so as to clarify the role of the above two factors in the pathogenesis of AR.

Abstract
Surgical margin principle is one of the central surgical principles for head and neck cancers. Negative surgical margin is the primary purpose of surgery for head and neck cancers. This paper is based on the current clinical application of surgical margins of head and neck cancers, and it is proposed that surgical margins of head and neck cancers may be classified into three types: surface margin, deep margin, and tissue interface margin in consideration of surgical exposure of tumors. The classification of surgical margins can make the clinical application and the research of surgical margins of head and neck cancers more systematic and clear.

Abstract
At present, there are many monitoring devices for vital signs parameters for clinical selection, but urine monitoring has not received enough attention. The traditional manual visual measurement, intermittent measurement of urine pH value, and other methods are still in use, so the authors designed a multifunctional urine bag. The urine bag can set up an alarm system per unit time according to patient's age and condition as well as set up urine pH value detection area in hard plastic measuring bottle. This device can not only accurately monitor urine volume per unit time, but also hopefully realize the alarm automation of abnormal urine volume per unit time, as well as real-time dynamic monitoring of urine pH value. It is helpful for medical staff to make accurate judgment on patients' condition changes, to guide the formulation and modification of clinical treatment plans, and to reduce the workload of clinical nursing staff to a certain extent.

Abstract
Most of the common dizziness/vertigo diseases in otology clinic are peripheral vertigo diseases, and while about 20% -30% of all vertigo diseases are caused by central nervous system diseases. Pseudo vestibular neuritis, acute ischemic stroke with audiovestibular loss, and central paroxysmal positional vertigo are the three types of central "malignant vertigo" diseases which are most easily misdiagnosed by otologists. This article described the clinical characteristics and bedside physical performance of these three diseases, and summarized the differential diagnosis points for clinical reference.

Abstract
Objective:To investigate the clinical features of LC-BPPV with direction-fixed horizontal nystagmus in the primary Roll test. Method:Nine patients of LC-BPPV with bilateral direction-fixed horizontal nystagmus in the first Roll test were treated by repositioning maneuvers after judging the affected side and the prognosis was observed. Result:The affected side of eight patients was the side of the apogeotropic nystagmus. Barbecue or Gufoni maneuvers was effective for reposition. The other one had no conversion of nystagmus and could not judge the affected side. Conclusion:The nystagmus performance of patients with LC-BPPV is complicated. It is necessary to carefully analyze the nystagmus performance of each position. Combining with bow and lean test, lying down test and null plane, the position of the otolith is inferred. Comprehensive use of the Barbecue or Gufoni maneuvers, forced side lying on the affected side, mastoid sniper, shaking head method is effective to complete the reposition treatment.

Abstract
Objective: To investigate the methods for qualitative pathological assessment of dynamic changes in liver fibrosis/cirrhosis after antiviral therapy in patients with chronic hepatitis B (CHB), since antiviral therapy can partially reverse liver fibrosis and cirrhosis caused by hepatitis B and semi-quantitative, rather than qualitative, pathological assessment is often used for the research on liver fibrosis regression. Methods: Previously untreated CHB patients with liver fibrosis and cirrhosis were enrolled, and liver biopsy was performed before treatment and at 78 weeks after the antiviral therapy based on entecavir. The follow-up assessment was performed once every half a year. Based on the proportion of different types of fibrous septum, we put forward the new qualitative criteria called P-I-R classification (predominantly progressive, predominantly regressive, and indeterminate) for evaluating dynamic changes in liver fibrosis. This classification or Ishak fibrosis stage was used to evaluate the change in liver fibrosis after treatment and Ishak liver inflammation score was used to evaluate the change in liver inflammation after treatment. Results: A total of 112 CHB patients who underwent liver biopsy before and after treatment were enrolled, and among these patients, 71 with an Ishak stage of ≥3 and qualified results of live biopsy were included in the final analysis. Based on the P-I-R classification, 58% (41/71) were classified as predominantly progressive, 29% (21/71) were classified as indeterminate, and 13% (9/71) were classified as predominantly regressive; there were no significant differences between the three groups in alanine aminotransferase, aspartate aminotransferase, albumin, HBeAg positive rate, HBV DNA, and liver stiffness (P < 0.05). After treatment, the proportion of predominantly progressive, indeterminate, or predominantly regressive patients changed to 11% (8/71), 11% (8/71), and 78% (55/71), respectively. Among the 35 patients who had no change in Ishak stage after treatment, 72% (25/35) were classified as predominantly regressive and had certain reductions in the Laennec score, percentage of collagen area, and liver stiffness. Conclusion: This new P-I-R classification can be used to assess the dynamic changes in liver fibrosis after antiviral therapy in CHB patients.

Abstract
Objective:To study the differences in cognitive function between patients with laryngeal carcinoma and healthy volunteers. Method:Patients with laryngeal carcinoma who have been first diagnosed with laryngeal carcinoma, but not received treatment at the Department of Otolaryngology in two hospitals in Shanxi Province and healthy volunteers of the same age, gender-matched and similar education were studied for the purpose to evaluate the cognitive status by using the Wechsler memory scale.Result:No significant difference of age, gender and educational level was found between both groups(P>0.05).The score of Memory Quotient was significantly lower in the laryngeal carcinoma group than that in healthy control group (P<0.05). There were significant differences in the results of Wechsler memory scale except for Experience, Orientation and Association test (P<0.05).Conclusion:The memory, attention and computing power of patients in the laryngeal carcinoma group were not as good as those of patients in the healthy control group. Patients with laryngeal carcinoma have cognitive impairment or lower ability , so we need to pay more attention to the patients during their rehabilitation. The early detection of cancer-related cognitive impairments can help patients improve their cognitive function early, reduce the burden on their families and society, and promote better return of patients to society.

Abstract
Objective:The aim of this study is to investigate the clinical features of the patients with postviral olfactory dysfunction (PVOD). Method:Clinical information of 141 consecutive outpatients with PVOD were collected and analyzed based on a questionnaire, including age, gender, months of onset, and symptoms. Sniffin'Sticks Test was used as a psychophysical olfactory test to evaluate olfactory function. Result:Retrospective analysis of 141 patients with PVOD, the male to female ratio of patients was 1.0:2.3. The severity of olfactory dysfunction was found no significant difference between the man and the women (χ2=0.05,P>0.05). Patients aged from 30 to 40 years old and 50 to 60 years of age were vulnerable to PVOD. The most common nasal symptoms at the times of upper respiratory infection (URI) were nasal obstruction, rhinorrhea and sneezing, together with other symptoms, such as sore throat, sputum and cough. Conclusion:Analysis of clinical characteristics in a large sample shows that gender, age may be related to PVOD. However, our understanding of this complex disease is still limited and much more studies are necessary.

Abstract
Objective:To investigate effects of four different types of nasal packs after endoscopic sinus surgery. Method:Sixty patients with chronic rhinosinusitis who underwent endoscopic sinus surgery were evaluated preoperatively using visual analog symptom scale, Lund-Kennedy endoscopy scoring scale, and Lund Mackay CT scoring scale.All patients received nasal packing after operative, and divided into four groups based on the nasal packs used: nasopore group (16 cases), merocel group (16 cases), vaseline gauze group(16 cases) and merocel with vaseline gauze group(12 cases). All packs were removed 48 to 72 hour after the surgery. Clinical effects of four nasal packs were evaluated based on following indexes: pain after twelve hours of nasal packing, bleeding during nasal packing, pain and bleeding during packing removal, difficulty of packing removal. Result:The lowest degree of forementioned five different indexes was found in Nasopore group, and was significantly different with other three groups(P <0.05), merocel produced the highest bleeding during nasal packing,which had significant difference with other three groups(P <0.05), vaseline gauze produced the highest pain during nasal packing and packing removal, which had significant difference with other three groups(P <0.05), merocel combined vaseline gauze had no significant difference with merocel on the pain during nasal packing and packing removal(P >0.05), and it had no significant difference with vaseline gauze on bleeding during nasal packing, bleeding upon packing removal and degree of difficulty or ease upon packing removal(P >0.05).Conclusion:As a new type of high expansion absorbable nasal packing products applied after FESS, nasopore has the advantages of good hemostatic effect,higher nasal comfort level,least bleeding upon packing removal and so on. At the same time, the implementation of personalized mixed nasal packing of different materials could make up for the various defects when used alone,gained better clinical effect and worthy of clinical popularization and application.

Abstract
OBJECTIVE To explore the DNA methylation sites correlated with blood pressure (systolic blood pressure, diastolic blood pressure, mean arterial pressure, pulse pressure) in adult twin population. METHODS A total of 476 twins from the Chinese National Twin Registry were selected as the research population. Questionnaires were used to collect demographic characteristics, lifestyle, disease status and other information, and blood pressure, height, weight and other anthropometric indicators were measured. The genome-wide DNA methylation of whole blood samples was detected by using Infinium HumanMethylation450 BeadChip. The DNA methylation sites correlated with blood pressure were analyzed by constructing mixed effect model with adjusting potential confounding factors, and the significant level was false discovery rate <0.05. RESULTS After data quality control, 465 twins (122 pairs of monozygotic twins, 104 pairs of dizygotic twins, 13 individuals from 13 pairs of twins) aged (44.8±13.2) years were finally enrolled. There were more males and more monozygotic twins, and the current smokers and current regular drinkers both accounted for more than 30%. No significant CpG site was found after multiple testing in the correlation study between genome-wide DNA methylation and blood pressure by using the collected twins. However, the cg07761116 located on chromosome 10 had low P value in the correlation analysis of 3 blood pressure indices (systolic blood pressure, diastolic blood pressure, mean arterial pressure), suggesting that this site might be correlated with blood pressure. The other 7 sites had low P value in the correlation analysis of the two blood pressure indices, respectively, which pointed to genes involved in neurological development, protein homeostasis, inflammatory reaction and other pathways. CONCLUSION There is no sufficient evidence to support any DNA methylation site correlated with blood pressure, which may be caused by insufficient sample size and other reasons. This study could provide a reference for subsequent similar twin studies, and subsequent studies can focus on the cg07761116 located on chromosome 10 and other sites with low P values.

Abstract
Glioma is the most common primary tumor in the brain, accounting for about 40~50% of intracranial primary tumors. Most chemotherapeutic drugs have difficulty in penetrating the blood-brain barrier, and their clinical applications are greatly limited. We evaluated the effects of methylmercury-L-cysteine (MeHg-L-cys) and methylmercury chloride (MMC) on apoptosis of C6 glioma cells. L-type amino acid transporter (LAT1) was used to investigate the targeted transport function and cytotoxicity of MeHg- L-cys in glioma. MeHg-L-cys enhanced the ability of targeting glioma cells and reduced the adverse reactions to normal brain tissues. Therefore, it is significantly important to develop new anti-glioma drugs targeting the blood-brain barrier.

Abstract
Modulation of apoptosis is therapeutically effective in cardiomyocytes damage. Calenduloside E (CE), a naturally occurring triterpenoid saponin, is a potent anti-apoptotic agent. However, little is known about its synthetic analogues on the protective effects in apoptosis of cardiomyocytes. The present research was performed to investigate the potential protective effect of CE analogues against H2O2-induced apoptosis in H9c2 cardiomyocytes and the underlying mechanisms. Sixteen novel CE anologues have been designed, synthesized and biological evaluation. Among the 16 CE anologues, as well as the positive control CE tested, compound 5d was the most effective in improving cardiomyocytes viability. Pretreatment with anologue 5d inhibited ROS generation, maintained the mitochondrial membrane potential and reduced apoptotic cardiomyocytes. Moreover, exposure to H2O2 significantly increased the levels of Bax, cleaved caspase-3, and cleaved PARP, and decreased the level of Bcl-2, resulting in cell apoptosis. Pretreatment with anologue 5d (0.02-0.5 μg/mL) dose-dependently upregulated antiapoptotic proteins and downregulated proapoptotic proteins mentioned above during H2O2-induced apoptosis. These results suggested that CE analogues provide protection to H9c2 cardiomyocytes against H2O2-induced oxidative stress and apoptosis, most likely via anti-apoptotic mechanism, and provided the basis for the further optimization of the CE analogues.

Abstract
Objective: To observe the outcome of breast reconstruction with autologous fat grafting in the patients following treatment for breast cancer. Methods: The clinical data of 22 patients after breast cancer modified radical mastectomy with fat grafting for breast reconstruction from January 2012 to March 2015 at Department of Body Contouring and Liposuction Center of Plastic Surgery, Hospital of Peking Union Medical College were analyzed retrospectively. The age of 22 patients (all female) was 28 to 54 years. Fifteen patients were performed breast modified radical mastectomy 5 to 16 year ago without radiotherapy, 7 patients were performed breast modified radical mastectomy following regular radiotherapy 2 years ago. Low negative pressure liposuction technical was applied to harvest fat tissue for 400 to 800 ml which was filtrated and purified by cotton pad method in low temperature environment. Fat grafting was performed with multi-level and multi-tunnel and in multi-point injection ways. All patients were followed up by regular imaging evaluation with MRI or ultrasonography after operation every 3 months. Results: All breast reconstruction were successfully performed in 22 patients, no severe complications occurred. Among 15 patients without radiotherapy, 12 patients were performed with autologous fat grafting for breast reconstruction, 3 patients with prosthetic implantation for breast augmentation after autologous fat grafting. Among 7 patients with radiotherapy, 6 patients were performed with autologous fat grafting for breast reconstruction, 1 patient with prosthetic implantation for breast augmentation after autologous fat grafting. The volume of fat grafting was 104 to 380 ml. It took 2.5 hours to finish the operation including 1.0 to 1.5 hours for liposuction and 40 minutes for fat grafting. Next fat grafting were performed after 3 months. The fat of the breast were survived well detecting by MRI, only 1 patient had a cystic nodule which had been resected during nipple reconstruction. Ultrasonography screened several cystic nodules with the major axis of 0.1 to 0.2 cm in the breast, which couldn't be found by palpating in 18 patients. The patients were followed up for 18 to 36 months, the outcome were satisfactory. Conclusion: Autologous fat grafting for breast reconstruction simplifies the operation program with satisfied results and avoids the complications of breast reconstruction with skin flap.

Abstract
Vocal nodules in children is one of the common diseases in children, characterized as the hoarse voice of the children, which is mainly due to improper use of sound long-term or excessive use of the voice. The hoarseness of children's voice undermine not only the physical and mental health of children, but also the quality of life of children and their families. In recent years, the incidence of vocal nodules in children has been increasing. There are considerable differences between the children's own characteristics and adults such as bronchial lumen and cognitive and cooperate aspects, which lead to a large number of difficulties for clinical diagnosis and intervention. Based on a large number of literatures, this paper reviews the risk factors, diagnosis, voice assessment and intervention strategies of vocal nodules in children, in order to provide more comprehensive reference for the medical workers.

Abstract
Objective:To investigate the effects of hsa-miR-193b on the proliferation and apoptosis of Hep-2 cells.Method:The experiment was divided into Blank, NC, and miR-193b inhibitor. We used the qRT-PCR to identify the expression of miR-193b in Hep-2 cells. Cell proliferation was monitored using the MTT assay kit. Cell cycle and apoptosis were analyzed by flow cytometry. Cell invasion was monitored using the Transwell assay staining. The target of miR-193b was forecasted by bioinformatics.The expression level of SMAD3 protein was detected by Western blot. Result:After miR-193b inhibitor transfection, qRT-PCR showed that the expression of miR-193b was downregulated significantly (compared with Blank and NC,P<0.01),and there was no significant difference between Blank and NC(P>0.05). Compared with NC, miR-193b inhibitor induced a significant inhibition of cells growth at 24 h, 48 h and 72 h(P<0.05,P<0.01 and P<0.01), and flow cytometry revealed that miR-193b inhibitor significantly promoted cell apoptosis(P<0.01) and cell cycle was blocked in G1/S stage(P<0.01), meanwhile miR-193b inhibitor also inhibited the invasive property of Hep-2 cells(P<0.01). Predicting outcomes indicated that SMAD3 was a target of miR-193b. Furthermore, the over-expression of miR-193b down-regulated the expression of SMAD3(compared with NC,P<0.05). Conclusion:miR-193b inhibitor can inhibit the proliferation, migration and invasion abilities, and promote the apoptosis of Hep-2 cells. It indicates that miR-193b acts as an "oncogene" for laryngal squamous cell carcinoma and may serve as a novel antitumor target of therapy.

Abstract
Objective: To explore the association between DNA methylation and body mass index (BMI) using Mendelian randomization analysis. Methods: A total of 469 participants were selected from the Chinese National Twin Registry in 2013, who were living in Shandong, Jiangsu, Zhejiang, and Sichuan provinces, and at least 18 years of age. A questionnaire survey and physical examination were conducted to collect demographic, clinical, and behavioral information. Peripheral blood cells were collected to detect genotype and methylation status. Association analyses between DNA methylation and BMI and between CpGs and cis-SNP were conducted. With rs748212 as the instrumental variable, the association between cg15053022 and BMI was explored using the Mendelian randomization method. Results: A total of 469 participants were selected. The mean age of participants was (44.8±13.2) years and the BMI was (25.0±3.8) kg/m(2). Nine BMI-related DNA methylation sites were found and DNA methylation site cg15053022 in the ATP4A gene was negatively associated with cis-SNP rs748212 (β=-0.020); the mean methylation level of AA, AC, and CC were 0.212±0.025, 0.242±0.024, and 0.264±0.028, respectively. rs748212 was associated with BMI (β=0.04, P=0.007) and closely related to cg15053022 (F=237.66, P=0.143). Mendelian randomization analysis showed lower methylation levels at cg15053022 were associated with higher BMI (β=-1.97, P<0.001). Conclusion: This study supported the impact of cg15053022 methylation in the ATP4A gene on BMI using Mendelian randomization analysis and provided the basis for using Mendelian randomization analysis in methylation studies.

Abstract
Objectives In order to screen the altered gene expression profile in peripheral blood mononuclear cells of patients with osteoporosis, we performed an integrated analysis of the online microarray studies of osteoporosis. Methods We searched the Gene Expression Omnibus (GEO) database for microarray studies of peripheral blood mononuclear cells in patients with osteoporosis. Subsequently, we integrated gene expression data sets from multiple microarray studies to obtain differentially expressed genes (DEGs) between patients with osteoporosis and normal controls. Gene function analysis was performed to uncover the functions of identified DEGs. Results A total of three microarray studies were selected for integrated analysis. In all, 1125 genes were found to be significantly differentially expressed between osteoporosis patients and normal controls, with 373 upregulated and 752 downregulated genes. Positive regulation of the cellular amino metabolic process (gene ontology (GO): 0033240, false discovery rate (FDR) = 1.00E + 00) was significantly enriched under the GO category for biological processes, while for molecular functions, flavin adenine dinucleotide binding (GO: 0050660, FDR = 3.66E-01) and androgen receptor binding (GO: 0050681, FDR = 6.35E-01) were significantly enriched. DEGs were enriched in many osteoporosis-related signalling pathways, including those of mitogen-activated protein kinase (MAPK) and calcium. Protein-protein interaction (PPI) network analysis showed that the significant hub proteins contained ubiquitin specific peptidase 9, X-linked (Degree = 99), ubiquitin specific peptidase 19 (Degree = 57) and ubiquitin conjugating enzyme E2 B (Degree = 57). Conclusion Analysis of gene function of identified differentially expressed genes may expand our understanding of fundamental mechanisms leading to osteoporosis. Moreover, significantly enriched pathways, such as MAPK and calcium, may involve in osteoporosis through osteoblastic differentiation and bone formation. Cite this article: J. J. Li, B. Q. Wang, Q.

Abstract
Vocal fold nodules is the common cause of the hoarseness,which seriously affected people's living standard.At present,the treatment of the vocal fold nodules should be based on conservative treatment,surgical treatment as a supplement.Conservative treatment mainly includes:rest the voice,drug treatment,intervention and voice therapy.Surgical treatment is mainly the laryngomicrosurgery in suspension laryngoscope. The purpose of this study is to summarize the diagnosis and the treatment of vocal fold nodules,improving the reference of clinical workers.
