The current document is based on a consensus reached by a panel of experts from the Chinese Society of Allergy and the Chinese Society of Otorhinolaryngology-Head and Neck Surgery, Rhinology Group. Chronic rhinosinusitis (CRS) affects approximately 8% of Chinese adults. The inflammatory and remodeling mechanisms of CRS in the Chinese population differ from those observed in the populations of European descent. Recently, precision medicine has been used to treat inflammation by targeting key biomarkers that are involved in the process. However, there are no CRS guidelines or a consensus available from China that can be shared with the international academia. The guidelines presented in this paper cover the epidemiology, economic burden, genetics and epigenetics, mechanisms, phenotypes and endotypes, diagnosis and differential diagnosis, management, and the current status of CRS in China. These guidelines—with a focus on China—will improve the abilities of clinical and medical staff during the treatment of CRS. Additionally, they will help international agencies in improving the verification of CRS endotypes, mapping of eosinophilic shifts, the identification of suitable biomarkers for endotyping, and predicting responses to therapies. In conclusion, these guidelines will help select therapies, such as pharmacotherapy, surgical approaches and innovative biotherapeutics, which are tailored to each of the individual CRS endotypes.

PURPOSE: We aim to examine nasopharyngeal carcinoma (NPC) characteristics and survival outcomes in patients aged 70 years and older in the intensity-modulated radiotherapy (IMRT) era. MATERIALS AND METHODS: From 2006 to 2013, 126 non-metastatic NPC patients aged ≥ 70 years who were treated with IMRT +/‒ chemotherapy were included. Adult Comorbidity Evaluation 27 (ACE-27) was used to measure patient comorbidities. The overall survival (OS) and cancer-specific survival (CSS)were calculatedwith the Kaplan-Meier method, and differenceswere compared using the log-rank test. The Cox proportional hazards model was used to carry out multivariate analyses. RESULTS: For the entire group, only two patients (1.6%) presented stage I disease, and up to 84.1% patients had stage III-IVB disease. All patients had a comorbidity score of 0 in 24 (19.0%), 1 in 45 (35.7%), 2 in 42 (33.3%), and 3 in 15 (11.9%) patients. The main acute grade during radiotherapy was 3-4 adverse events consisting of mucositis (25.4%), bone marrow suppression (16.7%), and dermatitis (8.7%). After treatment, four patients (3.2%) developed temporal lobe injury. Five-year CSS and OS rates were 67.3% (95% confidence interval [CI], 58.6% to 77.4%) and 54.0% (95% CI, 45.6% to 63.9%), respectively. Five-year OS was significantly higher for ACE-27 score 0-1 than ACE-27 score 2-3 (72.9% and 39.9%, respectively; p < 0.001). Multivariate analyses showed ACE-27 score 0-1 was significantly associated with superior OS (hazard ratio [HR], 3.02; 95% CI, 1.64 to 5.55; p < 0.001). In addition, the rate of OS was higher for stage I-III than that of stage IV, with borderline significance (HR, 1.67; 95% CI, 0.99 to 2.82; p=0.053). But no significant advantage was observed in OS when chemotherapy was used (p > 0.05). CONCLUSION: Our findings suggest IMRT +/– chemotherapy has a manageable toxicity and provides an acceptable survival in patients aged ≥ 70 years with NPC. ACE-27 score was significantly associated with survival outcomes in this group population.

Objective To establish the method for isolation and culture of urine-derived stem cells (USCs) from female patients with interstitial cystitis/bladder pain syndrome (IC/BPS).Methods The USCs were collected from fresh midstream urine samples from 6 female IC/BPS patients admitted to our hospital from June 2018 to December 2018.The 6 patients were 33-55 years old (average 41.5 years old),and their course of illness was 2-18 years (average 8 years).The USCs were isolated from the urine through times of centrifugation and cultured in specific medium.Growth curve and cell cycle of USCs were observed.The expression of surface markers of USCs was analyzed by flow cytometry and immunofluorescence,the smooth muscle and epithelial differentiation potential of USCs were detected by immunofluorescence staining of surface markers of smooth muscle cells and epithelial cells.Results USCs were successfully extracted from 3 of 6 female patients,and the success rate reached 50％ by once extraction.USCs showed a "rice-grain" spindle appearance and showed logarithmic growth.USCs expressed surface markers associated with mesenchymal stem cells (e.g.CD44,CD73,CD105,CD133) and embryonic stem cells [e.g.stage-specific embryonic antigen 4 (SSEA4)] and pericytes[e.g.CD146,platelet derived growth factor beta receptor (PDGFRB) and NG2],but didn't express hematopoietic stem cell surface markers(e.g.CD31,CD34 and CD45).When induced to smooth muscle cells or epithelial cells,the cells expressed the surface markers of smooth muscle cells [e.g.desmin,myosin,alpha-smooth muscle actin(otSMA) and vimentin] and epithelial cells(e.g.uroplakin 1A,uroplakin 3B,AE1/AE3 and cytokeratin 13).Conclusions The method of isolation and culture of USCs from female IC/BPS patients was successfully established,and it provides a preliminary technical method for exploring the application of USCs in the clinical study of IC/BPS patients with autologous treatment.

Objective To evaluate the effect of local flaps on repair of defects after surgical removal of nasal skin tumors.Methods A total of 65 patients with nasal skin tumors were enrolled from Department of Dermatology,People's Hospital of Xinjiang Uygur Autonomous Region between March 2015 and August 2016,and subjected to surgical removal of the nasal skin tumors.According to the location,size,shape and surrounding skin of the nasal defects,nasolabial fold flaps,modified rhomboid flaps,bilobed flaps or frontal nasal flaps were chosen to repair skin and soft tissue defects.Results Of the 65 patients with nasal skin tumors,38 had basal cell carcinoma,20 pigmented nevus,5 keratoacanthoma,and 2 had squamous cell carcinoma.The lengths of the defects after resection were all below 2.5 cm.Nasolabial fold flaps were used in 32 cases,modified rhomboid flaps in 16,bilobed flaps in 12,and frontal nasal flaps in 5.All the flaps survived after the surgery,and no obvious deformation of the nose was observed.No recurrence was observed during 1 year of follow-up.Conclusion For skin defects with the length ≤ 2.5 cm after resection of nasal skin tumors,nasolabial fold flaps,modified rhomboid flaps,bilobed flaps and frontal nasal flaps can be used to repair wounds,with satisfactory efficacy.

Objective To acquire the basic information on diagnostic radiology and radiotherapy institutions and the frequency of medical radiation of Hebei province in 2016.Methods A survey was made using questionnaires for basic information on medical X-ray diagnosis,interventional radiology,radiotherapy and clinical nuclear medicine.Values of frequencies were derived for each type of medical X-ray procedure by dividing the total population.Results In 2016 there were 2 951 institutions at province level and 6 966 pieces of equipment involved in diagnostic radiology and radiotherapy treatments.Frequency values were estimated to be 379.25 examinations per 1 000 population in medical X-ay diagnosis,2.31 per 1 000 in interventional radiology,0.55 per 1 000 in radiotherapy and 1.65 per 1 000 in clinical nuclear medicine.The frequency for CT examination was 136.39 per 1 000,accounting for 36％ of the total frequencies in the province,with average annual growth rate of 12.4％.The highest value of frequency in clinical nuclear medicine was from Shijiazhuang among all types of medical procedures in different regions,11 times higher than the lowest value found in Hengshui city.Although the number of tertiary hospitals only accounted for 2.3％ of the total number of institutions,they contributed 25.5％,by examination number,of the medical X-ray diagnosis and 35.3％ of the CT examination.Interventional radiology and radiotherapy contributed more than 70％ of the total frequencies in the province,and clinical nuclear medicine was as high as 97.7％.Conclusions The basic information on diagnostic radiology and radiotherapy institutions and the frequency of medical procedures in Hebei in 2016 have been preliminarily made clear.Medical exposure could maintain a long-term growth trend.The frequency distribution of medical procedures in various regions and medical institutions is highly unbalanced.It is desirable to enhance the macroeconomic regulation and the management of medical radiation protection in order to rationally perform all types of diagnostic radiology and radiotherapy treatments to protect the health and safety of the patients and the examined individuals,and to promote the sustainable development of the health care services.

Objective To scale the frequencise of medical X-ray diagnosis based on the survey conducted in 58 hospitals to the all hospitals in Henan province,in order to make them available for providing the basis for reasonable application of diagnostic radiology.Methods Stratified sampling method was used to select medical institutions at different levels in 6 cities in the province as sample hospitals.The information of examined patients on sex,age,diagnostic type and exposure category were gathered and the results were analyzed.Results The sex ratio of male and female examined patients was close to 1∶1.The largest proportion,60.47％,of examined patients was from the age group of above 40 years old among the three age groups.Medical diagnositc medical X-ray examinations mainly include conventional X-ray photography and CT examination,accounting for 52.15％ and 40.31％,respectively.Chest examination contributed the largest propotions,23.84％,of conventional diagnositic X-ray examination and,13.25％,of CT examination respectively.CT examinations were mainly concentrated in the secondary and tertiary hospitals,accounting for 21.54％ and 72.99％ of the total CT examinations,respectively.Contrast examination,mammography and extracorporeal lithotripsy were concentrated in the tertiary hospitals,accounting for 77.82％,95.01％ and 100％ of the same type of examinations,respectively.Conventional photographic examinations were mainly conducted in primary hospitals,accounting for 74.56％ of all types of examinations in the primary hospitals.By using multiple linear regression model,the diagnostic examination frequency in 2016 was estimated to be 826 examinations per 1 000 population,of which the frequency of dianostic X-ray examination and CT examination were 541 per 1 000 and 285 per 1 000,respectively.Conclusions The frequency of diagnostic radiology in Henan has increased rapidly in recent years.All types of diagnostic radiology equipment are unevenly distributed in hospitals at different levels which posed a challenge for health care.Relevant departments should make efforts to reallocation of diagnostic radiology equipment in such hospitals and make utilization of health resources more reasonable.

Objective To explore the cognitive process of cognitive flexibility in obsessive-compulsive disorder patients. Methods Thirty-two patients with obsessive-compulsive disorder (OCD) and thirty-two healthy controls were included. The Task Switch paradigm and event-related potentials were used to assess cognitive flexibility. Results The accuracy rate was lower in the OCD than in control group in both repeat and switch trials (P＜0.05). Reaction time analysis revealed significant differences in both repeat and switch between the OCD and controls ( P＜0.05). ERPs revealed significant differences in N2 and P3 amplitudes between OCD and controls (P＜0.05). There was no significant correlation between cognitive flexibility (accuracy rate and reaction time of repeat and switch, and N1, N2 and P3 amplitudes) and clinical forced symptoms in OCD (P＞0.05). Conclusion Obsessive-compulsive disorder of cognitive flexibility by injured.

OBJECTIVE: To investigate the effect of a modified Wuzi Yanzong Pill (, WZYZP) on the male rats' testis after microwave radiation, as well as its potential mechanism. METHODS: Forty-five male rats were randomly assigned to three groups: the control group, the radiation group, and the WZYZP group. The rats in the radiation group and WZYZP group were exposed to microwave radiation for 15 min once, while the rats in the control group were not exposed to any radiation. The rats in the WZYZP group were given a modified of WZYZP by gavage daily for 7 days. Apoptosis in the testis was evaluated using terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. Histopathological alterations of the testis were observed by haematoxylin-eosin (HE) staining. Tat-interactive protein, 60kD (Tip60) and p53 expressions were determined by Western blotting. RESULTS: The apoptosis index (AI) in the radiation group was higher than that of the WZYZP group and control group on day 1 (D1), day 7 (D7) day 14 (D14) after radiation (P<0.05). The seminiferous tubules were of normal morphology in the control group. In the radiation group, the partial seminiferous tubules were collapsed, basement membranes of the seminiferous epithelia became detached. WZYZP could restore the morphological changes. There was no expression of Tip60 among the three groups on D7 and D14. The expression of p53 was higher in the radiation group than in the control group (P<0.05). WZYZP could down-regulate the rising p53 induced by radiation on D7 and D14 (P<0.05). CONCLUSION A modified WZYZP may affect germ cells, and its protective effects may partly result from its ability to intervene in Tip60 mediated apoptosis.
