ABSTRACT
Objective:To establish the Ultra-High Performance Liquid Chromatography (UPLC) characteristic chromatogram of different parts of Alpinia oxyphylla Miq., and to compare different parts of the chemical components based on multivariate statistical analysis. Methods:The UPLC was used to establish the fingerprint of Alpinia oxyphylla Miq. . The chromatograms were matched to generate the UPLC charactersistic chromatogram of different parts. Based on the variance analysis of single factor, combined with the Principal Component Analysis (PCA) ,Cluster Analysis (CA) and the Partial Orthogonal Least Square Discriminant Analysis (OPLS-DA) to analyze the differences of different medicinal parts of Alpinia oxyphylla Miq.. Results:16 common peaks of Alpinia oxyphylla Miq. were demarcated in crude drugs, compared with the medicinal materials of Alpinia oxyphylla Miq., the peak 13 (tectochhrysin) was lost in the decoction pieces, and the shell were missing peak 5 and peak 6. The results of PCA and CA showed that 15 batches of different medicinal parts of Alpinia oxyphylla Miq. can be broadly divided into 3 categories. The OPLS-DA result showed that the value of the peak area of peaks 14 (Nootkatone), 4, 7 and 12 were the main factors affecting the chemical composition of different parts of Alpinia oxyphylla Miq. .Conclusion:The fingerprint determination method established in this study is stable and controllable, which could distinguish the different parts of Alpinia oxyphylla Miq. .
ABSTRACT
Gene therapy is expected to restore the function of genetic material fundamentally and it has become a new trend in inherited retinal dystrophy treatment.Antisense oligonucleotide (AON) is a kind of small molecule nucleic acid drug, which can specifically bind to messenger RNA through the base pairing principle, thus interfering or modifying gene expression at the transcription and translation level.Possessing the advantages of high specificity and efficiency, wide targeting range, low immunogenicity and limited adverse effect, AON has become a novel remedy for inherited retinal dystrophy.Currently, three different AON drugs have already been used in clinical trials for inherited retinal dystrophy.In this review, the chemical structure modification, properties and mechanism of AON, and the therapeutic strategies of AON in different inherited retinal dystrophy diseases in recent years were summarized.
ABSTRACT
Objective@#To investigate the etiology, clinical and pathological characteristics of laryngeal leukoplakia and the predictive risk factors of recurrence and malignant transformation.@*Methods@#Clinical data of 263 patients with laryngeal leukoplakia between January 2000 and December 2015 were analyzed retrospectively.@*Results@#The pathological diagnoses included squamous epithelial hyperplasia (54.4%), mild dysplasia (17.9%), moderate dysplasia (12.2%), severe dysplasia and carcinoma in situ (12.5%), and invasive carcinoma (3.0%). Age and the extent of lesion were statistically different among different pathological groups (P<0.05). Gender, smoking and alcohol consumption did not show statistical differences among different pathological groups (P>0.05). Follow-up of 215 patients, excluding 6 cases of invasive carcinoma. The recurrence rate was 20.6%(43/209), and the malignant transformation rate was 5.3%(11/209). Multivariate analysis showed that pathological classification of moderate to severe dysplasia was the independent risk factor for recurrence and malignant transformation of laryngeal leukoplakia (P<0.05). In patients with severe dysplasia and carcinoma in situ, the recurrence proportion of conservative treatment, vocal cords (partial) resection and radiotherapy were 8/10, 0/10 and 2/11 respectively.@*Conclusions@#Laryngeal leukoplakia occurs frequently in elderly men with long-term smoking history. Pathological diagnoses are different. The grade of dysplasia is the predictive risk factor for the recurrence and malignant transformation of laryngeal leukoplakia. More aggressive treatment and closer follow-up should be warranted for patients with moderate dysplasia, severe dysplasia and carcinoma in situ.
ABSTRACT
Objective@#To explore the safety and validity of endoscopic cricopharyngeal myotomy in patients with cricopharyngeal achalasia.@*Methods@#A total of 19 patients with cricopharyngeal achalasia suffered from sustained dysphagia were enrolled in this study. The patients were divided into transcervical cricopharyngeal myotomy(CPM) group and endoscopic CPM (ECPM) group. Swallowing function and complications were evaluated.SPSS7.0 software was used to analyze the data.@*Results@#The swallowing function improved significantly in seven patients in ECPM group, and 9 patients improved in CPM group.The video fluoroscopic swallowing study(VFSS)-swallowing score, VFSS-aspiration score and drinking test score were (3.1±1.1), (3.4±0.8) and (2.0±0.6)in post-ECPM, (3.4±1.4), (3.0±0.9) and (2.2±0.6)in post-CPM. No statistical difference was found in validity between CPM group and ECPM group(t=-0.435, t=1.086, t=-0.607, P>0.05). No statistical difference was observed on the occurrence of complication between two groups. Only one patient had subcutaneous emphysema after operation in ECPM.@*Conclusions@#New surgical instruments and endoscopic surgical technique were safe and effective for cricopharyngeal achalasia. Because these instruments are cheaper, laryngeal endoscopic cricopharyngeal myotomy is easier to be popularized more easily than microscopic laser assistted CPM.
ABSTRACT
Objective@#To investigate the clinic feature, pathology, therapy and prognosis of the sarcomatoid caricinoma or carcinosarcoma of the larynx.@*Methods@#We reviewed the clinical records of 7 patients with laryngeal carcinosarcoma /sarcomatoid caricinoma who were treated at our hospital between June 1996 and August 2016. All patients were men (mean age, 65.9 years; range, 52 to 94 years). Among 7 patients, 6 had a history of smoking; 2 underwent radiotherapy; and 5 patients who didn′t undergo radiotherapy complained of hoarseness. The glottis was the most frequent site of involvement. Most tumors exhibited a polypold or pedunculated gross morphology. Among the 5 patients who didn′t undergo a radiotherapy, 2 were in stage Ⅰ, 2 in stageⅡ, and 1 in stage Ⅲ. The other 2 cases underwent surgeries and radiotherapy were staged.@*Results@#All 7 patients received surgeries, without lymph node metastasis. All the tumors were pathologically carcinosarcoma/sarcomatoid carcinoma. With immunohistochemistry examination, Vimetin was positive in all tumors, SMA positive in 3 tumors, S-100 positive in 1 tumors, but CD-68, HMB-45 or Myglobin was negative in all tumors. With follows-up from 3 months to 20 years, of 7 patients, 4 survived without recurrent, 1 dead, and 2 lost connection.@*Conclusions@#Both of the carcinosarcoma and the sarcomatoid carcinoma of larynx contain pathologically carcinoma and sarcoma. Surgery is the best choice for laryngeal sarcomatoid carcinoma, and these patients without a undergoing radiotherapy before surgery or these with little sarcoma in tumors show better prognosis.
ABSTRACT
Objective@#To introduce the method of transoral coblation-assisted endoscopic minimally invasive surgery for superficial tongue base tumour.@*Methods@#A total of 15 patients treated with transoral coblation-assisted endoscopic minimally invasive surgery from Mar. 2006 to Aug. 2016 were retrospectively reviewed. There were 9 patients with malignant tumors, 6 patients with benign neoplasms. Adjuvant postoperative radiation therapy was applied in three cases of squamous cell carcinoma, neck was performed in four cases of cancer. One case of non-Hodgkin lymphoma received postoperative chemotherapy.@*Results@#One case with ectopic thyroid gland was treated by subtotal resection and one case with squamous cell carcinoma changed into open surgery because of major lingual artery bleeding. The En bloc resection under edoscope was achieved in 92.86%(13/14)of patients. Fifteen cases of neoplasms were followed-up for 8-50 months(median 20 months), one patient with Cowden syndrome was lost to follow-up because of appendical carcinoid combined pulmonary metastasis, one patient with non-Hodgkin lymphoma died of recurrence in other head neck areas 2 years after chemotherapy.@*Conclusion@#Transoral coblation-assisted endoscopic surgery can successfully treat for the patients with superficial tongue base tumours.
ABSTRACT
Objective@#To explore the feasibility and effectiveness of transoral surgery (TOS) for the treatment of hypopharyngeal carcinoma by means of the radiofrequency coblation(RFC).@*Methods@#Twenty-two patients with hypopharyngeal carcinoma who were treated with TOS using RFC during the years of 2010-2016 were enrolled. Among these patients, 15 suffered from pyriform sinus carcinoma, 4 suffered from postcricoid carcinoma, and 3 suffered from posterior hypopharyngeal wall carcinoma. According to the AJCC 2002 guideline, the tumor stages were T1N0M0 for 3 patients, T2N0M0 for 9 patients, T1N1M0 for 1 patient, T1N2M0 for 1 patient, T2N1M0 for 4 patients, and T2N2M0 for 4 patients respectively. All patients with N+ underwent concurrent neck dissection; 2 patients underwent concurrent prophylactic tracheotomy; 17 underwent post-operative radiotherapy for 50-66 Gy. The follow-up time was 6-72 months with a median 35 months.Two patients were lost to follow-up.@*Results@#All patients except 2 underwent the TOS successfully, while the two patients were treated with open approach surgery due to unsure safe margin. Most patients returned to oral feeding within one week. Among the 18 patients with complete follow up data, 3 had the local recurrence of the tumor (16.7%) and one died due to local recurrence, multiple primary esophageal carcinoma, and distant metastasis 4 years after surgery (5.6%). According to the Kaplan-Meier method, the 5-years local control rate and survival rate were 57.8% and 67.5% respectively. All patients had no disorders in speech, swallowing and respiration during the follow up.@*Conclusions@#The RFC can be applied in TOS for the treatments of hypopharyngeal carcinoma with high cutting efficiency and better control of intraoperative hemorrhage, which is useful in lowering the operation difficulty. The oncologic results are comparable to the open surgery with satisfactory postoperative organ function preservation.

<p><b>OBJECTIVE</b>To investigate the clinical value of localization of upper airway obstructive site with the method of combination of nasopharyngeal airway and polysomnography (PSG).</p><p><b>METHODS</b>Forty-seven patients diagnosed as obstructive sleep apnea hypopnea syndrome (OSAHS) by PSG were enrolled. Each patient was examined by Somte PSG for the first night, underwent repeated PSG examination with the nasopharyngeal airway in place for the second night and received airway continuous pressure measurements (ApneaGraph) examination for the third night. The standard of treatment success was defined as apnea-hypopnea index (AHI) less than 20/h and a reduction of 50% or more. The patients were divided into success group and failure group. The PSG indices and ApneaGraph data of the two groups were compared. Correlations between AHI with nasopharyngeal airway in place by PSG and lower AHI and constituent ratio of lower obstruction by ApneaGraph were calculated. SPSS 17.0 software was used to analyze the data.</p><p><b>RESULTS</b>Forty-two patients completal three-night examination. With the nasopharyngeal airway in place, AHI, the lowest oxyhemoglobin saturation (LSaO2), average oxyhemoglobin saturation, percent of sleep time with oxyhemoglobin saturation <0.90 (SaO2 < 0.90T%) were improved obviously (P < 0.001). Twenty-nine patients (69.0%) achieved treatment success. There were statistical differences (t = 2.670, P = 0.011; Z = -3.252, P = 0.001 and t = -4.556, P < 0.001) of LSaO2 by PSG, lower AHI and constituent ratio of lower obstruction by ApneaGraph compared success group with failure group. The correlations between AHI with nasopharyngeal airway in place by PSG and lower AHI and constituent ratio of lower obstruction by ApneaGraph were 0.616 (P < 0.001) and 0.526 (P < 0.001).</p><p><b>CONCLUSION</b>The method of combination of nasopharyngeal airway with PSG is a reliable method of localization of upper airway obstructive site and can be used as a simple means to find out if there's any retroglossal obstruction.</p>

OBJECTIVE@#To investigate the relevance and clinical value of synchronous monitoring with Apnea Graph (AG) and micro movement sensitive mattress sleep monitoring system (MSMSMS) for the patient with obstructive sleep apnea-hypopnea syndrome before surgery.@*METHOD@#One hundred and fifteen patients diagnosed as OSAHS by PSG were synchronous examined by two methods: MSMSMS and AG with continuous upper airway pressure recording at night in Peking Union Medical College Hospital. The apnoeic and oxygen desaturation events during sleep determined by the two methods were compared. The correlation between MSMSMS and AG were analyzed.@*RESULT@#According to the OSAHS severity grading: the mild, moderate and severe were 6, 16, 93 for AG and 8, 26, 81 for MSMSMS respectively, and the hypoxemia severity grading:the mild, moderate, severe were 14, 70, 27 for AG and 6, 72, 37 for MSMSMS respectively. There were no statistically difference in the severity grading of OSAHS and hypoxemia during sleep determined by AG and MSMSMS. According to the parameters of the two methods, the AHI are (51.5 +/- 21.2) times/h (x +/- s, similarly hereinafter) and (48.1 +/- 24.2) times/h, r = 0.947; the LSaO2 are 0.736 +/- 0.110 and 0.710 +/- 0.108, r = 0.935; the correlation coefficient (r) of apnea index and obstructive apnea and hypopnea index were 0.856 and 0.841, P < 0.01 respectively, the data monitored by the two methods is positively correlated.@*CONCLUSION@#There is no significant difference in determining the severity of OS AHS between the AG and MSMSMS. The two methods had good correlation in respiratory disturbance index and oxygen decline index, and revealed well-prospects of preoperative assessment in patients with OSAHS.

Objective To assess the value of upper airway narrowing with MSCT under quiet respiration in patients with the obstructive sleep apnea-hypopnea syndrome (OSAHS). Methods CT scan of upper airway was performed in 63 patients with OSAHS during inspiration, expiration and quiet respiration respectively with 16-slice spiral CT. The state of the soft palate, the area of the smallest cross-sectional area of retropalatal and retroglossal space of the upper airway during the different respiratory phase were compared. The correlation between these dimensions and the polysomnography (PSG) results were analyzed. Results Some particular pattern of events occurred in 14 patients during the different phase of respiration, such as hooking of the soft palate, raising of the soft palate, artifacts, etc. These events occurred more often in the expiration phase. The cross-sectional area of the retropalatal space was the smallest during quiet breathing. There were statistically significant differences in the smallest cross-sectional area of retropalatal space among different phases of respiration (F=4.602, P＜0.05), also between inspiration and expiration, quiet breathing groups. No statistically significant difference was found between expiration and quiet breathing, nor in the smallest cross-sectional areas of retroglossal space among the three groups (P＞0.05). There was positive correlation between the smallest area of retropalatal space and LSaO_2 in quiet breathing and expiration groups (r=0.511, 0.300, P＜0.05). Conclusion MSCT scan of upper airway may be a better way to evaluate upper airway narrowing under quiet breathing when patients failed to carry out the required mode (keeping exhalation) or some undesirable events occurred.
ABSTRACT
Objective To evaluate the changes of the upper airway of the patients with obstructive sleep apnea syndrome (OSAS) before and after operations and to know the effects of operations by MSCT. Methods The upper airway dimensions of 26 patients with OSAS were measured on multiplanar reformatted (MPR), curved-planar reformatted (CPR), volume rendering(VR) images of 16-slice spiral CT. The measurements include the anteroposterior calibres and the areas on the reformatted axial images on the pharyngeal cavity levels, the calibres and the minimum areas in retropalatal and retroglossal regions, the areas of the soft palate and uvula on the reformatted sagittal view with maximum thickness, the maximum wall thickness of the right and left the upper airway on the coronary images, the volume of the upper airway before and after the operations. The measurements were correlated with the polysomnography (PSG) records. The data were analyzed paired-samples t-test and Pearson correlations. Results By comparison, the anteroposterior calibres and the cross-sectional areas on the reformatted axial view of the lower retropalatal region (slice 4) of the upper airway increased significantly after operations. The anteroposterior diameter increased from 5. 9 mm before operations to 12.8 mm after operations, where t = - 5.506, P < 0.05. The areas increased from 51.0 mm~2 before operations to 275.0 mm~2 after operations, where t = -5.011, P <0.05. In the higher retropalatal region (shce 2) of the upper airway, the anteroposterior diameter decresased from 14.8 mm before operations to 9.2 mm after operations, where t = 2.867, P < 0.05. The areas decreased from 241.0 mm~2 before operations to 128.0 mm~2 after operations, where t = 3.087, P < 0.05. The anteroposterior calibres of retroglossal region (slice 7) decreased from 12.7 mm before operations to 10.3 mm after operations,where t = 3.718, P <0.05. The L-R calibres and the minimum areas of of retropalatal increased significantly from 6.4 mm, 33.0 mm~2 before operation to 10.9 mm, 76. 0 mm~2 after operation, where t = -3.413, -2. 216, respectively and P < 0.05. Of the 9 cases whose apnea and hypopnea index (AHI) ≤5 events/hour after operations, the minimum areas of retropalatal region, the anterio-posterior diameter, L-R calibres increased significantly. The areas increased from 41.0 mm2 before operations to 76.0 mm~2 after operations, were t = -4. 932, P <0.05. The anteroposterior calibres increased from 4.6 mm before operations to 6.6 mm after operations, where t = - 7. 308, P < 0.05. The L-R calibres increased from 8.3 mm before operations to 13.6 mm after operations, where t = - 4.320, P < 0.05. Conclusions MPR、CPR、VR of MSCT can evaluate the not only the morphology but the function changes of the upper airways on the OSAS patients. The increasing of the minimum cross-sectional area may be one of the important indications for evaluating operations. The narrowing of the higher retropalatal region of the upper airway after operations should be an alert to the clinicians.
ABSTRACT
OBJECTIVE@#To investigate the dynamic changes in the upper airway that cause the obstructive sleep apnea-hypopnea syndrome by measuring the variations of upper airway pressures in the palatal segment of oropharynx and in segment of laryngopharynx.@*METHOD@#The two pressure sensors of the manometer: Apnea Graphs were positioned below uvula and upper esophagus. By comparing the difference between the two sites with the reference of outer atmospheric pressure and using two temperature sensors to determine the air flow through the nose and mouth, we got apnea and hypopnea index (AHI) of 21 patients of obstructive sleep apnea-hypopnea syndrome at the supine position and siding position and obtained the information about the site of upper airway collapse and obstruction.@*RESULT@#1. The AHI was (47.83 +/- 18.05) per hour for supine position, while (35.11 +/- 18.88) per hour for lateral position in the studying group. The difference between these two groups is statistically significant (P < 0.05). 2. The apnea events were mainly caused by the collapse and obstruction of palatal segment of oropharynx which constitute 84.48% of the obstruction. The collapse at the segment of laryngopharynx was responsible for 12.58% of the obstruction.@*CONCLUSION@#The upper airway pressure measurements could provide direct informations about the obstructive sleep apnea-hypopnea syndrome. These informations help choosing appropriate operation for apneic patients.
