Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Severe insulin resistance syndrome associated with mutations in the insulin receptor(INSR) gene is rare in clinical practice. We report a 13-year-old female patient with insulin resistance, acanthosis nigricans, and Class Ⅱ malocclusion, whose family history included hyperinsulinemia in both her mother and grandmother. Whole-exome sequencing and PCR-Sanger validation identified a novel INSR mutation, c. 637delA(p.S213Vfs*69), resulting in a pathogenic variant that substitutes serine at position 213 with valine. This case highlights a clinical phenotype that is challenging to differentiate between Rabson-Mendenhall syndrome and A-type insulin resistance syndrome. Long-term follow-up is crucial to assess disease progression and prognosis.

Objective: To examine the feasibility and surgical approach of removing type D trigeminal schwannoma through nasal cavity and nasal sinus under endoscope. Methods: Eleven patients with trigeminal schwannoma who were treated in the Department of Otorhinolaryngology, Qilu Hospital of Shandong University from December 2014 to August 2021 were analyzed retrospectively in this study. There were 7 males and 4 females, aged (47.5±13.5) years (range: 12 to 64 years). The neoplasm involved the pterygopalatine fossa, infratemporal fossa, ethmoidal sinus, sphenoid sinus, cavernous sinus, and middle cranial fossa. The size of tumors were between 1.6 cm×2.0 cm×2.0 cm and 5.7 cm×6.0 cm×6.0 cm. Under general anesthesia, the tumors were resected through the transpterygoid approach in 4 cases, through the prelacrimal recess approach in 4 cases, through the extended prelacrimal recess approach in 2 cases, and through the endoscopic medial maxillectomy approach in 1 case. The nasal endoscopy and imaging examination were conducted to detect whether neoplasm recurred or not, and the main clinical symptoms during follow-up. Results: All the surgical procedures were performed under endonasal endoscope, including Gross total resection in 10 patients. The tumor of a 12-year-old patient was not resected completely due to huge tumor size and limited operation space. One patient was accompanied by two other schwannomas located in the occipital region and the ipsilateral parotid gland region originating from the zygomatic branch of the facial nerve, both of which were removed concurrently. After tumor resection, the dura mater of middle cranial fossa was directly exposed in the nasal sinus in 2 cases, including 1 case accompanied by cerebrospinal fluid leakage which was reconstructed by a free mucosal flap obtained from the middle turbinate, the other case was packed by the autologous fat to protect the dura mater. The operation time was (M(IQR)) 180 (160) minutes (range: 120 to 485 minutes). No complications and deaths were observed. No recurrence was observed in the 10 patients with total tumor resection during a 58 (68) months' (range: 10 to 90 months) follow-up. No obvious change was observed in the facial appearance of all patients during the follow-up. Conclusion: Type D trigeminal schwannoma involving pterygopalatine fossa and infratemporal fossa can be removed safely through purely endoscopic endonasal approach by selecting the appropriate approach according to the size and involvement of the tumor.

ObjectiveTo understand the physical development level of 3-7 years old children in Zhag′yab， and to provide reference for local health decision-making. MethodsA cross-sectional study was conducted between June 2021 and July 2021， with a sample of 1 247 Tibetan children aged 3-7 years from kindergartens in 13 districts of Zhag′yab. Their height and weight were measured and the hemoglobin was detected by a unified method. Standard statistical method was adopted （Z-score method）. Z-scores of length /height-for-age （HAZ）， Z-scores of weight-for-age （WAZ）， Z-scores of body mass index （BMI）-for-age （BAZ） and Z-scores of weight-for-height （WHZ） were calculated by WHO Anthro v3.2.2 and WHO Anthro Plus. The nutritional status of children was evaluated according to WHO diagnostic criteria for malnutrition and anemia. ResultsThe average WAZ and HAZ of children aged 3 to 7 in Zhag′yab were lower than the WHO standards，except for the WAZ of 4-year old， the differences were statistically significant （P<0.05）. The overall detection rate of malnutrition was 25.7%， stunting， underweight， wasting， overweight， obesity and anemia were 11.6%， 11.8%， 10.8%， 3.3%， 1.8% and 29.3%， respectively. The detection rates of all indicators in boys were higher than those in girls， and the differences were not statistically significant （P>0.05）. The overweight rate and obesity rate of rural children were lower than those of urban children， and the other detection rates were higher than those of urban children. The differences of underweight rate， obesity rate and anemia rate were statistically significant between urban and rural children （P<0.05）. Among the detection rates of all indicators in different age groups， there were statistically significant differences in the overweight rate and the anemia rate （P<0.05）. The overweight rate of children aged 4 and the anemia rate of children aged 5 were the highest. ConclusionsThe physical development of children aged 3 to 7 in Zhag′yab is poor， and the prevalence of malnutrition and anemia is high. Underweight and anemia are more serious in rural children， and the overweight and obesity problem of urban children is emerging. More attention should be paid to promote their nutritional status. The prevention and intervention of children’s malnutrition should be strengthened in Zhag′yab.

Animal survival necessitates adaptive behaviors in volatile environmental contexts. Virtual reality (VR) technology is instrumental to study the neural mechanisms underlying behaviors modulated by environmental context by simulating the real world with maximized control of contextual elements. Yet current VR tools for rodents have limited flexibility and performance (e.g., frame rate) for context-dependent cognitive research. Here, we describe a high-performance VR platform with which to study contextual behaviors immersed in editable virtual contexts. This platform was assembled from modular hardware and custom-written software with flexibility and upgradability. Using this platform, we trained mice to perform context-dependent cognitive tasks with rules ranging from discrimination to delayed-sample-to-match while recording from thousands of hippocampal place cells. By precise manipulations of context elements, we found that the context recognition was intact with partial context elements, but impaired by exchanges of context elements. Collectively, our work establishes a configurable VR platform with which to investigate context-dependent cognition with large-scale neural recording.

Human use experience(HUE) is important for the research and development of Chinese medicine. For the sake of more reliable data, the Professional Committee for Clinical Evaluation of Chinese Medicine of Chinese Pharmaceutical Association drafted the Expert Consensus on Human Use Experience Research of Traditional Chinese Medicine. It highlights that the research on HUE should have clear purposes, describe the theoretical basis of traditional Chinese medicine(TCM) for the clinical indications and prescriptions and the clinical value of prescriptions, especially the advantages or characteristics in clinical orientation and target population, evaluate the dosages and number of medicinals of prescriptions, verify the accordance with the preparation process of new Chinese medicine, analyze feasibility of the process for large-scale production and the rationality of the dosage form, and assess the medicinal material resources. Moreover, such research should have reasonable protocol and the collection of clinical data on HUE must comply with medical ethics and avoid conflicts of interest. The collection method should be selected depending on the characteristics of clinical data. Quality control measures should be formulated to ensure the authenticity, accuracy, completeness, reliability, and traceability of clinical data. The definitions on the clinical data should be uniform and clear, and methods should be adopted to avoid bias. The data can be statistically analyzed after the processing. Through the study of HUE, the clinical orientation, target population, commonly used dosage, course of treatment, preliminary efficacy and safety of Chinese medicine prescriptions will be clarified. On this basis, the data on the HUE should be discussed and conclusions will be drawn. Finally, a standardized report will be formed.

Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.

Cartilage and giant cell-related neoplastic lesions originating in the temporomandibular joint region have similar clinical, imaging and pathological manifestations, making the diagnosis of these disorders challenging to varying degrees. Diagnostic findings can influence treatment procedures and a definitive pathological diagnosis is important for the prognosis of these conditions. In this article, we discuss the pathological diagnosis and differentiation of four benign cartilage and giant cell related tumors and tumor-like lesions that occur in the temporomandibular joint, namely synovial chondromatosis, tumoral calcium pyrophosphate deposition disease, pigmented villonodular synovitis and chondroblastoma, taking into account their clinical features and histological manifestations, with a view to providing a basis for clinical management.
