Noninvasive continuous positive airway pressure (CPAP) for the ventilation treatment of obstructive sleep apnea-hypopnea syndrome (OSAHS) is the first-line treatment method. This article aims to describe the effect of surgical operation especially for the UPPP in the individualized comprehensive treatment of OSAHS and the importance of surgical technique. Lower compliance is the bottleneck of CPAP therapy in clinical application, for the OSAHS patients with treatment failure in CPAP or those cannot accept CPAP therapy, when with no other ideal instrument therapeutics, accurate diagnosis of position in airway obstruction with an adequate surgical operation is the treatment,of choice. Surgical operation is particularly important either as a fore-lying means to improve the CPAP treatment compliance or as an independence treatment method of OSAHS. The pharyngeal cavity is the most common obstructive plane in patients with OSAHS. The operation of traditional UPPP aiming at the expansion of pharyngeal cavity is the classics surgery to solve obstruction in this plane, the lower operation effective rate is the main reason of restriction in its development. How to improve the effective rate of surgical treatment of OSAHS is our surgical goal. The effective rate of surgical operation treatment in OSAHS rely on the following sides: to follow the OSAHS individualized comprehensive treatment principle, reasonable choice of surgical operation indication, the precise localization diagnosis of upper airway obstruction, adequate surgical operation and skilled surgical techniques.

Objective To observe the effect of high-dose vitamin C on MMP2 expression and invasive ability in PANC-1. Methods Transwell invasion assay was used to compare the invasive ability of PANC-1 cells in different concentrations of vitamin C treated groups. RT-PCR and Western blot were used to detect and compare the levels of MMP2 mRNA and protein expression in each group. Results Compared with the 0mM vitamin C treated group, the mRNA expression of MMP2 was significantly decreased in 1.0,5.0,10. 0mM group(0. 510 ±0. 004 vs 0. 792 ±0. 006, 0. 391 ±0. 007 vs 0. 792 ±0. 006, 0. 282 ±0. 008vs 0. 792 ± 0. 006, P ＜ 0. 05 ). Compared with the 0mM vitamin C treated group, the protein expression of MMP2 was significantly decreased in 1.0,5.0,10. 0mM group(0. 519 ±0. 004 vs 0. 761 ±0. 014,0. 310 ±0. 007 vs 0. 761 ±0. 014,0. 297 ±0. 008 vs 0. 761 ±0. 014, P ＜0. 05). Compared with the 0mM vitamin C treated group, the invaded cell number was significantly decreased in 1.0,5.0,10. 0mM groups ( 452 ± 22 vs653 ± 28,340 ± 32 vs 653 ± 28,409 ± 33 vs 653 ± 28, P ＜ 0. 05 ). Conclusion High-dose vitamin C can decrease the expression of MMP2 in PANC-1 cells, and weaken its invasive ability.

Objective:In order to prevent misdiagnosis and degrade death rate, we explored the early diagnosis and correct treatment methods of traumatic pseudoaneurysm of internal carotid artery in sphenoid sinus,. Method: The clinic data of 6 cases who had traumatic pseudoaneurysm of internal carotid artery in sphenoid sinus and were admited in our hospital were analyzed retrospectively. Large numbers of literature about the disease were re-viewed. Some early diagnosis methods and optimal treatment schemes were proposed. Result: All patients had a history of cranium trauma and recurrent attacks nasal hemorrhage. There are two patients with a complication of sight loss in single eye. In the six cases, one case was treated with unilateral common carotid artery ligation, three cases were treated with aneurysm and internal carotid artery embolism by using sacculus proprius which is able to shedding , one case was treated with internal carotid artery embolism by using tiny circlip ring . These five pa-tients were crued with no severe complication. One patient death of hemorrhea. His nasal cavity was tamponaded repeatly because repeat nasal hemorrhage. However, he had never treated with internal carotid artery embolism. Conclusion:The patients who have traumatic pseudoaneurysm of internal carotid artery usually die of unmanageable hemorrhea. The patients may be cured if they could obtain an early diagnosis and correct treatment.

This study examined the dynamic characteristics of upper airway collapse at soft palate level in patients with obstructive sleep apnea/hypopnea syndrome (OSAHS) by using dynamic 3-Dimensional (3-D) CT imaging. A total of 41 male patients who presented with 2 of the following symptoms, i.e., daytime sleepiness and fatigue, frequent snoring, and apnea with witness, were diagnosed as having OSAHS. They underwent full-night polysomnography and then dynamic 3-D CT imaging of the upper airway during quiet breathing and in Muller's maneuver. The soft palate length (SPL), the minimal cross-sectional area of the retropalatal region (mXSA-RP), and the vertical distance from the hard palate to the upper posterior part of the hyoid (hhL) were compared between the two breathing states. These parameters, together with hard palate length (HPL), were also compared between mild/moderate and severe OSAHS groups. Association of these parameters with the severity of OSAHS [as reflected by apnea hypopnea index (AHI) and the lowest saturation of blood oxygen (LSaO(2))] was examined. The results showed that 31 patients had severe OSAHS, and 10 mild/moderate OSAHS. All the patients had airway obstruction at soft palate level. mXSA-RP was significantly decreased and SPL remarkably increased during Muller's maneuver as compared with the quiet breathing state. There were no significant differences in these airway parameters (except the position of the hyoid bone) between severe and mild/moderate OSAHS groups. And no significant correlation between these airway parameters and the severity of OSAHS was found. The position of hyoid was lower in the severe OSAHS group than in the mild/moderate OSAHS group. The patients in group with body mass index (BMI)≥26 had higher collapse ratio of mXSA-RP, greater neck circumference and smaller mXSA-RP in the Muller's maneuver than those in group with BMI<26 (P<0.05 for all). It was concluded that dynamic 3-D CT imaging could dynamically show the upper airway changes at soft palate level in OSAHS patients. All the OSAHS patients had airway obstruction of various degrees at soft palate level. But no correlation was observed between the airway change at soft palate level and the severity of OSAHS. The patients in group with BMI≥26 were more likely to develop airway obstruction at soft palate level than those with BMI<26.

OBJECTIVE: It was aimed to investigate the effect of plasma radiofrequency ablation on obstructive sleep apnea hypopnea syndrome. METHOD: Fifty-four patients with OSAHS were treated with plasma radiofrequency ablation on soft palate, tonsil, uvula and root of tongue in light of needs. RESULT: All these cases were reevaluated with PSG by the end of postoperative period lasted for three month. Among them, 6 were cured, 24 had significant therapeutic effect, 19 had effective outcome, and 5 had no effective, with a total effective rate of 90.74%. No serious complications occurred. CONCLUSION This method was safe and effective, and patients had mild lesion, less bleeding, less painful and the advantages of simple operation.

Objective: To analyse monitoring absenteeism due to respiratory symptoms/diseases among preschoolers in Guangzhou, and to provide reference for risk prevention and control of respiratory infectious diseases in kindergartens. Methods: Data of absenteeism due to symptoms and diseases in kindergartens were collected from "Guangzhou Student Health Monitoring System", and was analyzed by using R 4.1.3 software. Results: During 2018-2020 academic year, there were 1 965, 2 019, 2 236 kindergartens being monitored respectively. The absenteeism rate of kindergarten s children due to respiratory symptoms and diseases in Guangzhou were 3.08‰ and 2.02‰. The absenteeism rates due to respiratory symptoms were 3.75‰, 4.17‰, 2.97‰ and 2.09‰ in baby class, junior class, middle class and senior class, respectively. The absenteeism rates due to respiratory diseases were 2.34 ‰, 2.60‰, 1.94‰ and 1.50‰, respectively. The absenteeism rate in higher grade was lower than that in lower grade( χ 2= 65 197.95 ，27 929.44， P <0.01). The absenteeism rates of boys (3.11‰, 2.05‰) due to respiratory symptoms/diseases were significantly higher than those of girls (3.06‰, 1.97‰)( χ 2=57.71，229.45， P <0.01). The absenteeism of preschoolers due to respiratory symptoms/diseases showed two peaks in December of the this year and May of the following year. At the beginning of the second semester of 2019 academic year (after the outbreak of Coronavirus disease 2019), the absenteeism rate due to respiratory symptoms/diseases were lower than those of the same period in previous years. Conclusions The absences due to respiratory symptoms or diseases not only accounted for half of the total absences due to illness, but also had seasonal characteristics. Children in the youngerage group and most boys are treated as a focus group for absence due to respiratory symptoms/illnesses. It s necessary to give full use of timely warning function of health monitoring system.

Objective: To investigate the association of poor vision with time spent in outdoor activity among students from primary and middle schools, as well as from universities in Guangzhou, so as to provide targeted scientific basis for prevention and control of low vision. Methods: According to the requirements of National Monitoring of Common Diseases and Health Risk Factors among Students Manual, a total of 2 908 students were selected in 1 urban area and 1 suburban county for monitoring and investigation in Guangzhou. Results: The poor vision rate was 69.2% among students in Guangzhou, with girls (74.4%) > boys (64.2%), suburban country (76.3%) > urban areas (54.1%), university (95.0%) > vocational high school (82.5%) > regular high school (81.1%) > junior high school (73.4%) > primary school (45.6%). With the exception of primary students, the severe poor vision has the largest proportion in each age group. The proportion of spending less than 1 or 2 h for outdoor activities per day: girls>boys, suburban country > urban area, university and regular high school are higher. The poor vision rate of students who spent <2 h(72.3%) for outdoor activities daily was higher than those spent ≥2 h(65.6%). Compared with students who spent ≥2 h/d for outdoor activities, those spent < 2 h/d were at 1.24 times risk of being low vision(OR=1.24, 95%CI=1.04-1.48), controlling for the available confounders. Conclusion Poor vision rate of students in Guangzhou is high, occurring mainly with severe impairment and in younger age, the daily outdoor activity time is low. Girls, students from suburban country and junior high school should be considered as the emphasis for prevention and control of low vision.

Objective:To investigate the safety and efficacy of drug-eluting stents(DES)in patients with acute coronary syndrome(ACS)complicated with diabetes and multivessel disease.Methods:A total of 80 patients with ACS who received XIENCE V Everolimus stent implantation in the heart center of the 82nd army hospital from January 2017 to October 2018 were retrospectively enrolled and analyzed.Patients were divided into the diabetic group(35 cases)and the non-diabetic group(45 cases)according to whether they were complicated with diabetes or mltivessel lesions.Stent implantation status within 12 months after PCI were compared between the groups.Results:(1)All stents were successfully implanted in the two groups.After coronary angiography re-examination within 12 months, there were no significant differences in the rate of stent restenosis(0.0% vs 2.2%), non-fatal myocardial infarction(2.9% vs.2.2%), or MACEs(2.9% vs.4.4%)between the diabetic and non-diabetic groups(all P>0.05). No patients died from cardiogenic causes in the two groups.(2)During the follow-up period, one patient was hospitalized for acute myocardial infarction in the diabetic group and one case died of an ascending aorta rupture. Conclusions:The safety and efficacy of XIENCE V DES in patients with diabetes and multivessel lesions are good, and the incidence of MACEs is low.

We analyze the epidemiology,clinical features,and outcome of the patients with Creutzfeldt-Jakob diseases (CJD) in Guizhou Province from 2010 to 2015.The epidemiology,clinical characteristics and follow-up data of CJD suspected patients obtained from Guizhou CJD surveillance network were analyzed.The testing results of cerebrospinal fluid (CFS) and blood from the patients were also collected and analyzed.Results showed that a total of 11 CJD cases was found from 23 reported CJD suspected patients in Guizhou from 2010 to 2015,including 8 probable sporadic CJD(sCJD) cases,2 possible sCJD cases and 1 genetic CJD(gCJD) case.In 11 cases,rapidly progressive dementia was the major initial symptom,following by mental symptoms,extrapyramidal symptoms,signs and cerebellum cortical blindness.Clinical symptoms of progressive dementia were the main symptoms,following by visual or cerebellar dysfunction,myoclonus,cone system/extrapyramidal dysfunction,and akinetic mutism.Most of cases were abnormal in MRI (45.45％) and 14-3-3 protein detection in CSF(70％).The 14-3-3 blood samples of prion gene 129 amino acids (PRNP)polymorphisms were M/M type,excepting for 1 case gCJD confirmed diagnosis cases with D178N mutation in PRNP gene.Eleven CJD cases did not show season and regional clusterings and vocational tendency.The majority of the cases were male,the median age was 65,and mainly were the Han nationality.For all cases of CJD reported during that year for follow-up,the lost-tofollow-up rate was 27％,and the majority of cases died within one year.The sCJD cases were the majority in CJD cases of Guizhou Province,2010-2015.The epidemiological characteristics were similar to the national monitoring cases in the same period.
