OBJECTIVETo observe and evaluate the clinical effects of surgical treatment for the accessory navicular syndrome with simple excision.

METHODSFrom November 2006 to December 2008, 23 patients (twenty-five feet) with accessory navicular syndrome received simple excision of the accessory navicular bone. The chief complains were intermittent pain of feet after running or walking. Physical examination showed local tenderness on palpation in the region of the navicular bone. X-ray or CT showed there was an accessory navicular bone. The present history ranged from 6 months to 12 years. There were 14 males and 9 females. The mean age was 14.6 years, ranging from 8 to 35 years. About 2 cm long incision was made at the tip of the medial prominence of the navicular bone. After partial dissection of the posterior tibial tendon, the accesssory navicular bone was exposed and excisied. The prominence of the tuberosity of the navicular bone was cut and shaved. The posterior tibial tenden was repaired before closing the wound. The foot was immobilized with cast or brace in inversion position and no weight-bearing for 2 weeks. Strenuous jumping or dancing must be avoided in 3 months after surgery. The patients with residual symptoms and signs received physical therapy and an arch support for shoes without flatfoot deformity.

RESULTSThe average clinical follow-up during was 12 month (ranged, 3 to 18 months). The excellent results in 21 feet and good in 4 feet (3 feet with mild flat deformity and 1 foot with old sprain injury). The average hospital stay was 5 days and no wound infection occurred. All patients resumed the normal life and study after operation.

CONCLUSIONSurgical treatment of the accessory navicular syndrome with simple excision has the advantages of less invasive to the posterior tibial tenden and the medial longitudinal arch of the foot, shorter time of immobilization of the foot and stay in hospital, small incision and good clinical results. This procedure is one of the best selective treatments for the accessory navicular syndrome, especially for the patients without flatfoot deformity and old sprain injury.

OBJECTIVETo sum up the follow-up outcomes of endoscopic modified Lothrop procedure (EMLP) and retrospectively analyze the indications, methods and prognostic factors of EMLP.

METHODSThe collected data of 73 cases who received EMLP with frontal sinus diseases were analyzed in this paper. The mean age was 45.6 (ranging from 14 to 72 years). There were 52 males and 21 females. Only patients with follow-up time greater or equal to 6 months were included. Paranasal sinus CT scan was adopted for all cases and MRI for tumor patients. All patients were followed under endoscope.

RESULTSThere were 21 inverted papilloma in the frontal sinus, 16 chronic sinusitis with asthma, 12 frontal sinusitis, 9 chronic sinusitis with or without polyps, 7 osteoma of the frontal sinus, 4 frontal mucocele, 3 allergic fungal sinusitis and 1 congenital encephalocele. Sixty-one cases had prior surgical history (1.8 times on the average). Their mean follow-up was 25.0 months, (ranging from 6 to 122 months). At the end of follow-up, 44 cases (60.3%) had well opened frontal drainage pathway. Twenty-five (34.2%) was re-stenosed and 4 (5.5%) closed. Seven cases (9.6%) underwent revision surgeries. There were no surgical complications.

CONCLUSIONSEMLP is an effective and salvage procedure in dealing with tumor of frontal sinus and recurrent frontal sinusitis. Combined with medical treatment, EMLP will have a better results for chronic sinusitis with or without polyps and asthma. The degree of diseases, mucosal loss, anatomic variability and prior surgeries are important prognostic factors.

OBJECTIVETo explore the impact of 36-hour sleep deprivation (SD) on the brain electrophysiological indicators of visuo-motor coupling in young soldiers.

METHODSDuring the 36-hour SD, 10 healthy young soldiers were tested on visuospatial rotation tasks by event-related potentials system before and after SD. The incubation period and amplitude of P500 as well as their error number and reaction time were measured.

RESULTSCompared with subjects in SD 0-hour,subjects in SD 36-hour had significantly increased error rate [(9.7 ± 3.9)% vs. (18.3 ± 4.5)%, P<0.05] and significantly increased reaction time [(632.5 ± 53.6) ms vs. (693.6 ± 65.7) ms, P < 0.05]. Subjects in SD 36-hour showed significantly reduced amplitudes than those in SD 0-hour [(8.7 ± 2.3) ΜV vs. (5.2 ± 1.6) ΜV, P < 0.05]. Additionally, subjects in SD 36-hour showed significantly increased P500 latencies than did those in SD 0-hour [(489.6 ± 42.6) ms vs .(530.2 ± 51.9) ms, P < 0.05]. Compared with subjects in SD 0-hour, the deficit was an absence of a mental rotation function SD 36-hour in subjects.

CONCLUSIONSThe 36-hour SD in young soldiers can harm the processing mechanism of visuo-motor coupling in a certain extent. SD can affect the fixed position ability of visual space cognition in young soldiers.

OBJECTIVETo provide evidence for more accurate diagnosis of birth defects based on the pathoanatomy of congenital malformations.

METHODSData used in this study were obtained from Luliang City Hospital and three county hospitals of Shanxi province between February 2004 and March 2006. Autopsy and pathological examination of 160 dead fetuses and stillbirths were performed. Photos of dead fetuses and stillbirths were taken, tissues were cut into sections for pathological examination under microscope, all pathological information was recorded, and percentage of birth defects was calculated.

RESULTSThe proportion of dead fetuses and stillbirths with or without congenital malformations was 84.4% (135/160) and 15.6% (25/160), respectively. There were 16 categories of major external and internal birth defects in 135 cases of such defects. Congenital heart defects, anencephaly and spina bifida had a higher prevalence rate in the study period. The prevalence rate of non-malformation death and birth defects < 28 gestational weeks and internal anomalies > or = 28 gestational weeks was 14.61% (61/4175) and 17.25% (72/4175), respectively. A total of 413 in situ anomalies were found in 135 cases of autopsy. Spina bifida, anencephaly, congenital heart defects, aplasia or accessory lobe of lung, renal agenesis and dysplasis and congenital hydrocephaly were more closely associated with severe malformations than with mitis malformations. The cases of dead fetuses and stillbirths with multiple malformations (> or = 2 in situ anomalies) had a higher proportion (74.1%), whereas those with isolated malformations had a lower proportion (25.93%).

CONCLUSIONThe occurrence of congenital malformations in different embryonic developmental stages affects multiple organs. Postmortem examination of internal and multiple malformations of fetal deaths and stillbirths can provide more accurate diagnostic information for birth defects.

BACKGROUNDAdenoid hypertrophy (AH) is associated with pediatric chronic rhinosinusitis (pCRS), but its role in the inflammatory process of pCRS is unclear. It is thought that innate immunity gene expression is disrupted in the epithelium of patients with chronic rhinosinusitis (CRS), including antimicrobial peptides and pattern recognition receptors (PRRs). The aim of this preliminary study was to detect the expression of innate immunity genes in epithelial cells of hypertrophic adenoids with and without pCRS to better understand their role in pCRS.

METHODSNine pCRS patients and nine simple AH patients undergoing adenoidectomy were recruited for the study. Adenoidal epithelium was isolated, and real-time quantitative polymerase chain reaction (RT-qPCR) was employed to measure relative expression levels of the following messenger RNAs in hypertrophic adenoid epithelial cells of pediatric patients with and without CRS: Human β-defensin (HBD) 2 and 3, surfactant protein (SP)-A and D, toll-like receptors 1-10, nucleotide-binding oligomerization domain (NOD)-like receptors NOD 1, NOD 2, and NACHT, LRR and PYD domains-containing protein 3, retinoic acid-induced gene 1, melanoma differentiation-associated gene 5, and nuclear factor-κB (NF-κB). RT-qPCR data from two groups were analyzed by independent sample t-tests and Mann-Whitney U-tests.

RESULTSThe relative expression of SP-D in adenoidal epithelium of pCRS group was significantly lower than that in AH group (pCRS 0.73 ± 0.10 vs. AH 1.21 ± 0.15; P = 0.0173, t = 2.654). The relative expression levels of all tested PRRs and NF-κB, as well as HBD-2, HBD-3, and SP-A, showed no statistically significant differences in isolated adenoidal epithelium between pCRS group and AH group.

CONCLUSIONSDown-regulated SP-D levels in adenoidal epithelium may contribute to the development of pCRS. PRRs, however, are unlikely to play a significant role in the inflammatory process of pCRS.

OBJECTIVETo present the changes of surgical approaches for the resection of juvenile nasopharyngeal angiofibromas (JNA) and the follow-up results.

METHODSThe clinical records of 59 patients with JNA treated under endoscope between 2002 and 2009 were reviewed retrospectively. The patients were divided into two groups: Group A (Radkowski I a-II b) and Group B (Radkowsik II c-III b). The tumor stages, feeding vessels, operating time, complications and recurrence were observed and recorded.

RESULTSThere were 7 patients with stage I a, 3 patients with stage I b, 5 patients with stage II a, 6 patients with stage II b, 4 patients with stage II c, 23 patients with stage III a, 11 patients with stage III b. The average age at diagnosis in Group A (21 cases) was 23.9 years old. The average operating time was (106.0 +/- 43.7) min. The follow-up ranged from 3 months to 74 months (median 36 months) except for 3 missing cases. The average age at diagnosis in Group B (38 cases) was 16.2 years old and the average operating time was (152.9 +/- 58.0) min. The follow-up ranged from 3 months to 87 months (median 25 months) except for 5 missing cases. During follow-up, 6 patients in group B recurred. Infarction of thalamencephalon happened in 1 patient in group B who recovered totally afterwards. The difference in operating time between two groups was statistically significant (t = -3.232, P = 0.002). The life table was used to evaluate the survival curves and Log-rank test showed that the difference of recurrent time between two groups was statistically significant (P = 0.03).

CONCLUSIONSThe key techniques to remove tumor are bleeding control, drilling-out the bone that tumor invaded. Transpterygoid or posterolateral wall of maxillary sinus approach are recommended for tumors that extend to infratemporal fossa. Small and intermediate-sized JNA which have no deep invasion of skull base (RadkowskiIa-II b) have a low morbidity. JNA at Radkowski stage IIc and above have residual and recurrent risk.

Air pollution, climate change, and reduced biodiversity are major threats to human health with detrimental effects on a variety of chronic noncommunicable diseases in particular respiratory and cardiovascular diseases. The extent of air pollution both outdoor and indoor air pollution and climate change including global warming is increasing-to alarming proportions particularly in the developing world especially rapidly industrializing countries worldwide. In recent years, Asia has experienced rapid economic growth and a deteriorating environment and increase in allergic diseases to epidemic proportions. Air pollutant levels in many Asian countries especially in China and India are substantially higher than are those in developed countries. Moreover, industrial, traffic-related, and household biomass combustion, indoor pollutants from chemicals and tobacco are major sources of air pollutants, with increasing burden on respiratory allergies. Here we highlight the major components of outdoor and indoor air pollutants and their impacts on respiratory allergies associated with asthma and allergic rhinitis in the Asia-Pacific region. With Asia-Pacific comprising more than half of the world's population there is an urgent need to increase public awareness, highlight targets for interventions, public advocacy and a call to action to policy makers to implement policy changes towards reducing air pollution with interventions at a population-based level.

There are geographical, regional, and ethnic differences in the phenotypes and endotypes of patients with drug hypersensitivity reactions (DHRs) in different parts of the world. In Asia, aspects of drug hypersensitivity of regional importance include IgE-mediated allergies and T-cell-mediated reactions, including severe cutaneous adverse reactions (SCARs), to beta-lactam antibiotics, antituberculous drugs, nonsteroidal anti-inflammatory drugs (NSAIDs) and radiocontrast agents. Delabeling of low-risk penicillin allergy using direct oral provocation tests without skin tests have been found to be useful where the drug plausibility of the index reaction is low. Genetic risk associations of relevance to Asia include human leucocyte antigen (HLA)-B*1502 with carbamazepine SCAR, and HLA-B*5801 with allopurinol SCAR in some Asian ethnic groups. There remains a lack of safe and accurate diagnostic tests for antituberculous drug allergy, other than relatively high-risk desensitization regimes to first-line antituberculous therapy. NSAID hypersensitivity is common among both adults and children in Asia, with regional differences in phenotype especially among adults. Low dose aspirin desensitization is an important therapeutic modality in individuals with cross-reactive NSAID hypersensitivity and coronary artery disease following percutaneous coronary intervention. Skin testing allows patients with radiocontrast media hypersensitivity to confirm the suspected agent and test for alternatives, especially when contrasted scans are needed for future monitoring of disease relapse or progression, especially cancers.

To provide a scientific evidence for the quality control of Codonopsis Radix, a method was established for determining the content of three free carbohydrates of Codonopsis Radix. The developed method showed good linearity. The calibration curves were linear within the range of 2.312 5-18.500 0 μg for sucrose, 1.500 0-12.000 0 μg for glucose, and 2.000 0-16.000 0 μg for fructose, resgectwely. The recoveries varied between 96.31%-101.8%. The method is simple, accurate and reproducible, and can be used for determining the content of sucrose, glucose and fructose of Codonopsis Radix. The results showed that different cultivation measures had an effect on the content of three free carbohydrates of Codonopsis Radix. According to the content of sucrose, using Zhuanggenling>not using Zhuanggenling. While, not pinching, shelving>not pinching, not shelving>pinching, not shelving>pinching, shelving. According to the content of glucose and fructose, not using Zhuanggenling>using Zhuanggenling. While, pinching, shelving>not pinching, not shelving>not pinching, shelving>pinching, not shelving. In consideration of the differences of sweetness and content of the three free carbohydrates in Codonopsis Radix, we recommend that the content of free carbohydrates could be considered as the marker to evaluate the quality of Codonopsis Radix.

Objective: To summarize the follow-up outcomes of frontal drill out procedures (draf Ⅱb, extended draf Ⅱb and draf Ⅲ) using mucosal flaps, and discuss the surgical indications of different mucosal flaps and their potential benefits to the opening of the frontal neo-ostium. Methods: A total of 48 patients with chronic rhinosinusitis or frontal mucoceles treated by draf Ⅱb, extended draf Ⅱb and draf Ⅲ between 2013 and 2019 in Beijing TongRen Hospital were enrolled in this study. Twenty-four patients who were treated with mucosal flaps were considered as mucosal flap group (including 19 males and 5 females, aging from 19 to 71 years), and the other 24 patients who didn't have neo-ostium reconstruction were considered as control group (including 18 males and 6 females, aging from 21 to 63 years). The frontal neo-ostium crosssectional area was measured with osiriX^® 7 days and 1 year postoperatively. Lund-Kennedy score (LKS) was also completed to analyze the difference of therapeutic effect between mucosal flap group and control group. SPSS 23.0 software was used for statistical analysis. Results: The postoperative follow-up time was 18 to 102 months. The postoperative epithelialization time in the mucosal flap group and the control group was (2.5±0.9) months and (3.0±0.7) months (Mean±SD), respectively, with statistically significant (t=1.97, P=0.024). At the end of follow-up, 23 cases (95.8%) had well opened frontal neo-ostium, 1 case (4.2%) was re-stenosed, and there was no revision surgery in the mucosal flap group. In the control group, 16 cases (66.7%) had well opened frontal neo-ostium, 8 cases (33.3%) were re-stenosed, 4 cases (16.7%) had revision surgery. The mucosal flap group had much fewer stenosis cases than control group (χ²=4.92, P=0.027). The neo-ostium area in the mucosal flap group and the control group was reduced by (0.87±0.58) cm² and (1.54±1.15) cm² 1 year after operation respectively, with statistically significant (t=1.72, P=0.046). There was no case of frontal sinus atresia and no surgical complication in both groups. The two-factor repeated measurement analysis of variance after surgery showed that the average LKS of the mucosal flap group was 0.78 points lower than that of the control group. In other words, the influence of grafting technique on LKS was statistically significant (F=5.33, P=0.035). Conclusions: The application of mucosal flaps to cover the denuded bone during frontal drill out procedures can prohibit mucosal scar and new bone formation, and significantly reduce the stenosis rate of frontal neo-ostium.
