Objective To compare the alaryngeal speakers'voice acoustic parameters and intra-tracheal pressure when they spoke different vowels.Methods 24 patients after tracheo-esophageal shunt phonation by the anastomosis of the membranous portion of the tracheal section with the anterior wall of esophagus after total laryngectomy and 16 esophageal speakers enrolled in this study. The voice acoustic parameters were measured when they spoke soft /a/ and soft /i/. The intra-tracheal pressure of 20 TE speakers was measured when spoke /a/ and /i/.Results There were no significant differences between vowel /a/ and /i/ in the two alaryngeal speaker group. The pressure of TE speakers after Shang's procedrue for comfortable /i/ was higher than that for /a/, and there was significant difference.Conclusion There were the same clinical meanings in evaluating alaryngeal voice acoustic aspect. when using vowel /a/ and /i/. However when using different vowel, the intrtracheal pressure was different in TE speakers.

Objective To explore the effects of sole desensitization physical therapy on standing balance and walking function among recovering stroke patients.MethodsStroke patients who met the inclusion criteria were randomly assigned to the observation group (40 cases) or the control group (40 cases). All patients received traditional rehabilitation. In addition, the observation group received sole densensitization physical therapy. The total course of treatment lasted for 1 month. The Berg balance scale (BBS) and Holden's functional ambulation classification (FAC) were used to evaluate balance and walking ability before and after treatment. The Fugl-Meyer assessment (FMA) was used to assess the motor function of the affected ankle, and footprint analysis was used to measure and record any changes in time and distance walked and to analyze improvements in gait.ResultsAfter the sole desensitization training, the BBS (37.41 ± 8.14), FAC ( 3.91 ±0.92) and FMA motor function (6.42 ± 1.12) results of the observation group were all significantly better than before training. Walking time and distance also improved.ConclusionsSole desensitization can affect foot proprioception. As a result, stroke patients' soles adapt to the surroundings, recover their ability to provide physiological support and promote improved motor function of the ankle.Sole desensitization can thus improve the standing balance and walking of stroke patients.

OBJECTIVE: To perform a Meta-analysis of all randomized controlled trials that compared the efficacy and adverse events profile of Mabs for LA HNSCC. METHOD: Several databases were searched, including CBM, PUBMED, EMBASE, and CENTRAL. Primary outcomes included overall response rate (ORR), overall survival (OS), progression-free survival (PFS). Secondary outcomes included serious adverse events, such as grade 3-4 skin reaction, dysphagia, mucositis, and nausea/vomiting. The results were expressed as relative ratio (RR) or hazard rate (HR) with their corresponding 95% CI. RESULT: The final analysis included 10 trials. The primary analyses indicated that Mabs did not improve ORR and PFS, except OS for locoregionally advanced (LA) HNSCC [ORR 1.21, 95% CI (0.97 - 1.49); PFS 0.87, 95% CI (0.75 - 1.01); OS 0.82, 95% CI (0.71 - 0.95)]. Analysis of adverse effects demonstrated that grade 3 - 4 skin reaction ERR 1.87, 95% CI (1.11 - 3.16)] was statistically significantly associated with Mabs except dysphagia ERR 0. 95, 95% CI (0.75 - 1.19)], Mucositis ERR 1.03, 95% CI (0.67 - 1.57)], and nausea/vomiting ERR 1.15, 95% CI (0.71 - 1.86)]. CONCLUSION Anti-EGFR Mabs may be satisfactory for improving OS of LA HNSCC. During the Mabs therapy, skin reaction should be much more monitored.

Objective To understand the children health care and the prevention of lead pollution in Panyu in the future by re-search on the detection result of blood lead from Panyu children during 2011 and 2012.Methods The detection of whole blood lead was by atomic absorption spectrometer from body examination in 6 308 children in Panyu Center Hospital be-tween 2011 and 2012:①The blood lead result from assigned children were divided into five age groups:infancy group (1~12 months,1 511 cases),toddler age group (1~2 years,1 558 cases),preschool age group (3~6 years,1 704 cases),school age group (7~11 years,1 076 cases)and adolescence group (12~18 years,459 cases).②Based on different age group,each group was separated by male and female.③According to the detection year,each group was also put into 2011 and 2012 re-spectively.Results The overall level of children blood lead in Panyu,Guangzhou in 2011 and 2012 was 37.01±29.18μg/L, and the total poisoning rate was 1.2 9%.Along with the growth of age,the overall level of children blood lead was in up-wards trend but the poisoning rate kept in a stable level beginning from infant stage.The blood lead level of boys in Panyu was 38.87±30.18μg/L,and the poisoning rate was 1.91%;the blood lead level of girls was 34.13±27.32μg/L,and the poisoning rate was 1.29%.The blood lead levels and the poisoning rates of boys were higher than girl’s in most of age groups.Conclusion Compared with other big cities like Guangzhou,the blood lead level of children in Panyu was declined but it’s not the standard performance,and there’s a certain extent of lead pollution.So in addition to reinforce pollution con-trol from government,parents and children should enhance the knowledge,education and precaution of lead poisoning.

AIM: Using simvastatin and vitamine E (Vit-E) treatment to coronary artery disease (CAD) patients with low HDL, to investigate the relationship between Ox-LDL, platelet activation and HDL. METHODS: 40 CAD patients with low HDL were divided into two groups (A and B): A group oral simvastatin, B group oral simvastatin and Vit-E. The level of serum Ox-LDL, TXB 2 and GMP-140 were measured before and after treatment. The relationship between Ox-LDL, TXB 2, GMP-140 and HDL were analysed. RESULTS:The level of serum HDL was significantly increased in A and B group after treatment and attained normal level. The level of serum Ox-LDL, TXB 2 and GMP-140 were decreased significantly after simvastatin and Vit-E treatment and neared normal. CONCLUSIONS:This study confirmed that HDL can effectively refrain LDL oxidation. It also revealed that Vit-E and simvastatin treatment were more effectively refrained platelet activation by increasement of HDL and decreasement of Ox-LDL.

Objective To investigate the in vivo transduction capability of fusion protein PEP-1-EGFP with mice.Methods Two prokaryotic expression plasmids pET15b-EGFP and pET15b-PEP-1-EGFP were constructed and transformed into E.coli BL21(DE3) to express EGFP and fusion protein PEP-1-EGFP,respectively.The expressed EGFP and PEP-1-EGFP were purified with Ni2+-resin affinity chromatography.Five hundred micrograms of EGFP and PEP-1-EGFP fusion protein were injected into mouse through caudal vein,respectively,the mice were euthanized and perfused with PBS 2 hours after administration.Then,the heart,brain,liver,spleen and kidney were removed and sectioned with a cryostat at 7 ?m for visualization with a inverted fluorescent microscope.ResultsThe brain,heart,liver,spleen and kidney injected with PEP-1-EGFP showed bright and homogenous green fluorescence whereas that with EGFP showed no green fluorescence at all.Conclusion The successful expression and purification of PEP-1-EGFP fusion protein and its efficient transduction into mice in vivo provide a basis for the research on transmembrane delivery of macromolecule drugs mediated by the cell-penetrating peptide,PEP-1.

OBJECTIVE: To evaluate the clinical application value of nasal airway obstruction objectively and quantificationally by acoustic rhinometry (AR) in children with adenoid hypertrophy. METHOD: Thirty patients with adenoid hypertrophy were examined with AR and questionnaire at preoperative and eight weeks after surgery. The values of AR were compared with those of 27 normal controls. RESULT: There were significant differences between preoperative and postoperative in NAR and NPV (P < 0.01), no significant difference was observed between preoperative and postoperative in MCSA (P > 0.05); There were significant differences in NAR, NPV, MCSA between the patient group and the control group (P < 0.01); There were significant differences between postoperative and the control group in NPV and MCSA (P < 0.01), no significant difference was observed between postoperative and the control group in TNAR (P > 0.05); There was negative correlation between MCSA and symptom scores (r = -0. 519, P < 0.05). No significant correlation was observed between NAR and NPV and symptom scores (P > 0.05). CONCLUSION Acoustic rhinometry was an objective and quantitative method for evaluating nasal airway in children with adenoid hypertrophy. In interpretation the relationships of the results of acoustic rhinometry reflection measurements and subjective symptoms, MCSA should be the main reference.

Objective: To quantitatively measure biological parameters of nanophthalmos and analyze the correlation between axial length (AL) and the other biological parameters. Methods: The clinical data of 71 eyes of 43 patients identified with nanophthalmos (AL≤20 mm) from September 2012 to August 2018 in Zhongshan Ophthalmic Center were retrospectively analyzed.All enrolled patients underwent ophthalmological examinations including best-corrected visual acuity, refraction, slit-lamp biomicroscopy, fundus examination, Goldmann applanation tonometry, A-scan ultrasound examinations, ultrasound biomicroscopy, spectral domain optical coherence tomography (SD-OCT) and nonmydriatic fundus photography.Pearson correlation analysis was used to analyze the relationship between AL and all biological parameters.This study followed the Declaration of Helsinki and was approved by the Ethics Committee of Zhongshan Ophthalmic Center (NO.2017KYPJ092). All patients signed informed consent. Results: Of the 43 patients, the average age was (46.00±12.75) years, the mean intraocular pressure was (24.97±14.87)mmHg (1 mmHg=0.133 kPa). The mean best corrected visual acuity was 1.14±0.79, the mean refraction was (11.61±4.09)D.The mean AL, central corneal thickness (CCT), central anterior chamber depth(ACD), anterior chamber width (ACW), len thickness(LT) and vitreous cavity length(VCL) was (17.13±1.57)mm, (550±60)μm, (1.64±0.37)mm, (11.17±0.61)mm, (5.01±0.51)mm and (10.10±1.80)mm, respectively.The average retinal nerve fiber layer thickness (mRNFLT), macular foveal retinal thickness (FRT) and subfoveal choroidal thickness (SFCT) was (98.51±40.93), (294.46±116.83) and (488.72±133.06)μm, respectively.The ratio of ACD to AL, LT to AL, and VCL to AL was 9.6%, 29.4% and 59.3%, respectively.The ACW and VCL were positively correlated with AL(r=0.432, 0.978; both at P<0.001); whereas, LT and FRT were negatively correlated with AL(r=-0.272, P=0.027; r=-0.679, P<0.001). There was no correlation between CCT, central ACD, mRNFLT, SFCT and AL (r=0.153, -0.053, -0.322, 0.063; all at P>0.05). Conclusions Nanophthalmos has the characteristics of narrow anterior and posterior segment structure.The ratio of LT to AL is increased and the ratio of VCL to AL is decreased.The AL is positively correlated with ACW and VCL, negatively correlated with LT and FRT.

Objective:To evaluate the efficacy and safety of limited pars plana vitrectomy(LPPV), pressure-controlled phacoemulsification(PCP), intraocular lens implantation(IOL), and posterior capsulotomy (PC) in treatment of nanophthalmic glaucoma eyes which intraocular pressure(IOP) were still out of control after peripheral iridectomy.Methods:All 24 patients(29 eyes) with nanophthalmic glaucoma whose IOP failed to be reduced after peripheral iridectomy and needed LPPV plus PCP plus IOL plus PC were recruited from July 2017 to April 2021. The age of these patients was(44.6±11.0) years old. Preoperative and postoperative IOP, best corrected visual acuity(BCVA), anterior chamber depth(ACD) and number of glaucoma medications were recorded by chart review and compared by using paired t-test or Wilcoxon signed rank-sum test. P<0.05 was considered as statistical significant. IOP could be controlled in normal range(≥5 mmHg and≤21 mmHg), without both of disease progression and serious complications were regarded as the success criteria of the operation. Surgical success rate was evaluated. Surgery-associated complications were recorded. Results:The average follow-up time was(11.52±12.44) months. After the microsurgery, IOP decreased from(33.12±9.25) mmHg to(14.23±3.44) mmHg( P<0.01); The ACD increased from(1.23±0.46) mm to(2.86±0.62) mm, and the median number of glaucoma medications dropped from 3(3,4) to 3(0,3) at final follow-up visit( P<0.05). There were no significant differences in BCVA( P=0.196) and the degrees of angle closure(AC) ( P=0.478) before and after operation. The total surgical success rate was 86.2%(25/29) at the final follow-up visit. Two eyes suffered from local choroidal detachment which recovered within 2 weeks with medical treatment. Conclusion:LPPV plus PCP plus IOL plus PC is a safe and effective novel surgical procedure in the treatment of nanophthalmic glaucoma patients with uncontrolled IOP after peripheral iridectomy. It could significantly decrease IOP, increase the depth of ACD, reduce the number of glaucoma medications and maintain BCVA. It can be considered as a first choice for the surgical management for patients with a such condition.

OBJECTIVETo investigate the clinicopathologic features and associated risk factors for bilateral neck node metastasis (BNM) in head and neck squamous cell carcinoma (HNSCC).

METHODSTwo hundred eighty-six cases with HNSCC were retrospectively studied, including 83 cases of oral tongue cancers, 101 cases of hypopharyngeal cancers and 102 cases of supraglottic laryngeal cancers. All patients had unilateral or bilateral cervical lymph node metastasis confirmed by postoperative pathologic examinations. The following factors were evaluated to determine the risk for BNM in HNSCC: T staging, size, location, trans-midline condition, growth pattern, pathologic grading and infiltration of primary tumors; N staging; the size, number and extracapsular spread (ECS) of ipsilateral metastatic nodes; the number of involved levels on the ipsilateral neck. Chi-square test and logistic regression test were used for statistical analysis.

RESULTSBNM was found in 86 (30.1%) of 286 patients with HNSCC, including 52 (18.2%) cases of contralateral occult neck node metastasis. The incidence of BNM was 35.6% (36/101) in hypopharyngeal cancer, 31.4% (32/102) in supraglottic laryngeal cancer and 21.7% (18/83) in oral tongue cancer, respectively. N staging, the number and ECS of ipsilateral metastatic nodes, and the number of involved levels on the ipsilateral neck were important factors contributing to BNM. Multiple logistic regression analysis revealed that midline passing of primary tumor was associated with BNM in oral tongue cancer. The midline passing and ECS of ipsilateral metastatic node were key factors for BNM in hypopharyngeal and supraglottic laryngeal cancers. T staging, size and midline passing of primary tumor were closely related to BNM in oral tongue cancer. T staging and midline passing were associated with BNM in hypopharyngeal cancer. Midline passing was an important factor related to BNM in supraglottic laryngeal cancer.

CONCLUSIONMidline passing of primary tumor is the most important factor determining BNM in hypopharyngeal, supraglottic laryngeal and oral tongue cancers, whereas ECS of ipsilateral metastatic node is the most important factor impacting BNM in hypopharyngeal and supraglottic laryngeal cancers.
