RESUMO
Objective: To evaluate the effect of preemptive analgesia with ibuprofen on postoperative pain following single posterior tooth implantation, aiming to provide a clinical reference for its application. Methods: A multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted. A total of 82 participants were included in the trial, meeting the eligibility criteria from April 2022 to April 2024 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), Beijing Chao-Yang Hospital, Capital Medical University (20 cases). Participants were randomly assigned in a 1â¶1 ratio to either the ibuprofen group or the control group, with each group comprising 41 individuals. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups received the same postoperative analgesic regimen for 3 days. Pain scores were assessed using the Numerical rating scale (NRS) at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h postoperatively, and the additional use of analgesic medication was recorded from days 4 to 6 postoperatively. Results: A total of 82 participants were initially enrolled in the study, with 7 dropouts (4 from the control group and 3 from the ibuprofen group), resulting in 75 participants (37 in the control group and 38 in the ibuprofen group) completing the trial. There were no reports of adverse events such as nausea or vomiting among the participants. The ibuprofen group exhibited significantly lower pain scores at 4 h, 6 h and 8 h [1.0 (0.0, 2.0), 1.0 (0.0, 2.0), 1.5 (0.0, 3.0) ] postoperatively compared to the control group 4 h, 6 h and 8 h [2.0 (1.0, 3.0), 3.0 (1.5, 4.0), 2.0 (1.0, 4.0)] (Z=-1.99, P=0.047; Z=-3.01, P=0.003; Z=2.10, P=0.036). The proportions of patients requiring additional analgesic medication between days 4 and 6 post-surgery were 18.4% (7/38) in the ibuprofen group and 27.0% (10/37) in the control group, with no significant difference (χ2=0.79, P=0.373). The median additional medication usage postoperatively was [0.0 (0.0, 0.0) pills] in the ibuprofen group and [0.0 (0.0, 1.0) pills] in the control group, with no significant difference (Z=-0.78, P=0.439). Conclusions: Preemptive analgesia with ibuprofen effectively reduces postoperative pain following tooth implantation, representing a safe and effective perioperative pain management strategy.
RESUMO
Objective: To understand the prevalence of major chronic diseases of diabetes, cardiovascular disease and malignant tumor in people living with HIV in Taizhou. Methods: The data were collected from China Information System for Disease Control and Prevention and Taizhou Chronic Disease Information Management System. A total of 5 126 people living HIV under follow-up in Taizhou from 1998 to 2022 were included in the analysis. Software SAS 9.4 was used for χ2 test, trend analysis and logistic regression analysis. Results: In the 5 126 people living with HIV, the reported prevalence rates of diabetes,cardiovascular disease and malignant tumor were 10.28% (527/5 126),3.98% (204/5 126) and 6.01% (308/5 126), respectively. 37.00% (195/527) and 48.58% (256/527), 40.20% (82/204) and 48.53% (99/204), 37.66% (116/308) and 48.38% (149/308) were diagnosed as diabetes, cardiovascular disease and malignant tumor before and after confirmation of HIV infection. From 2013 to 2022, the proportion of HIV infected people diagnosed with diabetes, cardiovascular disease and malignant tumor after confirmation increased (trend χ2=79.98,P<0.001; trend χ2=17.44,P<0.001; trend χ2=32.06,P<0.001). Based on the analysis on the factors for complicated chronic diseases in people living with HIV, it was found that women under 60 years old (aOR=0.66, 95%CI: 0.50-0.86) and those with access to antiviral treatment for >5 years before 2016 (aOR=0.54,95%CI:0.37-0.78) were less likely to develop complicated chronic diseases, and those under 60 years old with initial CD4+T lymphocytes counts <200 cells/µl (aOR=1.32, 95%CI: 1.02-1.70), those aged 40-49 and 50-59 years (aOR=2.88, 95%CI:2.20-3.79; aOR=5.43, 95%CI: 4.10-7.21) as well as those without a record of treatment medication use after 2016 (aOR=1.95,95%CI:1.20-3.16) were more likely to develop complicated chronic diseases. The probability of developing complicated chronic diseases might increase with age in people living with HIV. Conclusions: From 1998 to 2022, there was a certain proportion of complicated chronic diseases among HIV infected individuals in Taizhou, and the proportion of diagnosed cases increased after HIV infection was confirmed. It is necessary to conduct early chronic disease screening, behavior intervention and standardized management in people living with HIV.

BACKGROUND: Isoniazid (INH) is an important drug in many TB regimens, and unfavorable treatment outcomes can be caused by suboptimal pharmacokinetics. Dose adjustment can be personalized by measuring peak serum concentrations; however, the process involves cold-chain preservation and laboratory techniques such as liquid chromatography (LC)/mass spectrometry (MS), which are unavailable in many high-burden settings. Urine spectrophotometry could provide a low-cost alternative with simple sampling and quantification methods. METHODS: We enrolled 56 adult patients on treatment for active TB. Serum was collected at 0, 1, 2, 4, 6, and 8 h for measurement of INH concentrations using validated LC-MS/MS methods. Urine was collected at 0-4, 4-8, and 8-24 h intervals, with INH concentrations measured using colorimetric methods. RESULTS: The median peak serum concentration and total serum exposure over 24 h were 4.8 mg/L and 16.4 mg*hour/L, respectively. Area under the receiver operator characteristic curves for urine values predicting a subtherapeutic serum concentration (peak <3.0 mg/L) were as follows: 0-4 h interval (AUC 0.85, 95% CI 0.7-0.96), 0-8 h interval (AUC 0.85, 95% CI 0.71-0.96), and 0-24 h urine collection interval (AUC 0.84, 95% CI 0.68-0.96). CONCLUSION: Urine spectrophotometry may improve feasibility of personalized dosing in high TB burden regions but requires further study of target attainment following dose adjustment based on a urine threshold.
CONTEXTE: L'isoniazide (INH) est un médicament important dans de nombreux schémas thérapeutiques contre la TB, et des résultats thérapeutiques défavorables peuvent être dus à une pharmacocinétique sous-optimale. L'ajustement de la dose peut être personnalisé en mesurant les concentrations sériques maximales ; cependant, le processus implique la conservation de la chaîne du froid et des techniques de laboratoire telles que la chromatographie liquide (LC)/spectrométrie de masse (MS), qui ne sont pas disponibles dans de nombreuses régions à forte charge de morbidité. La spec-trophotométrie urinaire pourrait constituer une alternative peu coûteuse avec des méthodes d'échantillonnage et de quantification simples. MÉTHODES: Nous avons recruté 56 patients adultes sous traitement pour une TB active. Le sérum a été prélevé à 0, 1, 2, 4, 6 et 8 h pour mesurer les concentrations d'INH à l'aide de méthodes LC-MS/MS validées. L'urine a été prélevée à des intervalles de 04, 48 et 824 h, et les concentrations d'INH ont été mesurées à l'aide de méthodes colorimétriques. RÉSULTATS: La concentration sérique maximale médiane et l'exposition sérique totale sur 24 h étaient respectivement de 4,8 mg/L et de 16,4 mg*heure/L. L'aire sous les courbes caractéristiques de l'opérateur récepteur a été mesurée à l'aide de méthodes color-imétriques. Les aires sous les courbes caractéristiques des récepteurs pour les valeurs urinaires prédisant une concentration sérique sous-thérapeutique (pic <3,0 mg/L) étaient les suivantes : intervalle 04 h (AUC 0,85 ; IC 95% 0,70,96), intervalle 08 h (AUC 0,85 ; IC 95% 0,710,96), et intervalle de collecte d'urine 024 h (AUC 0,84 ; IC 95% 0,680,96). CONCLUSION: La spectrophotométrie urinaire peut améliorer la faisabilité d'un dosage personnalisé dans les régions à forte charge de TB, mais nécessite une étude plus approfondie de l'atteinte de la cible après l'ajustement de la dose sur la base d'un seuil urinaire.
RESUMO
Objective: To evaluate the impact of preemptive analgesia with ibuprofen on postoperative pain following the extraction of impacted mandibular third molars in a Chinese population, aiming to provide a clinical reference for its application. Methods: This multicenter, randomized, double-blind, placebo-controlled parallel-group trial was conducted from April 2022 to October 2023 at the Capital Medical University School of Stomatology (40 cases), Beijing TianTan Hospital, Capital Medical University (22 cases), and Beijing Chao-Yang Hospital, Capital Medical University (20 cases). It included 82 patients with impacted mandibular third molars, with 41 in the ibuprofen group and 41 in the control group. Participants in the ibuprofen group received 300 mg of sustained-release ibuprofen capsules orally 15 min before surgery, while the control group received a placebo. Both groups were instructed to take sustained-release ibuprofen capsules as planned for 3 days post-surgery. Pain intensity was measured using the numerical rating scale at 30 min, 4 h, 6 h, 8 h, 24 h, 48 h, and 72 h after surgery, and the use of additional analgesic medication was recorded during days 4 to 6 postoperatively. Results: All 82 patients completed the study according to the protocol. No adverse events such as nausea, vomiting, or allergies were reported in either group during the trial. The ibuprofen group exhibited significantly lower pain scores at 4 h [2.0 (1.0, 4.0) vs. 4.0 (3.0, 5.0)] (Z=-3.73, P<0.001), 6 h [2.0 (1.0, 4.0) vs. 5.0(2.5, 6.0)] (Z=-3.38, P<0.001), and 8 h [2.0 (1.0, 4.0) vs. 5.0 (2.0, 6.0)] (Z=-2.11, P=0.035) postoperatively compared to the control group. There were no statistically significant differences in pain scores between the groups at 30 min, 24 h, 48 h, and 72 h postoperatively (P>0.05). Additionally, 11 out of 41 patients (26.8%) in the ibuprofen group and 23 out of 41 patients (56.1%) in the control group required extra analgesic medication between days 4 and 6 post-surgery, with the ibuprofen group taking significantly fewer additional pills [0.0 (0.0, 1.0) vs. 1.0 (0.0, 3.0)] (Z=-2.81, P=0.005). Conclusions: A pain management regimen involving 300 mg of oral sustained-release ibuprofen capsules administered 15 minutes before surgery and continued for 3 d postoperatively effectively reduces pain levels and the total amount of analgesic medication used after the extraction of impacted mandibular third molars. Considering its efficacy, safety, and cost-effectiveness, ibuprofen is recommended as a first-line drug for perioperative pain management, enhancing patient comfort during diagnosis and treatment in a feasible manner.

The unique eco-environment of the Qinghai-Tibet Plateau breeds abundant microbial resources. In this research, Bacillus amyloliquefaciens GL18, isolated from the rhizosphere of Kobresia myosuroides from an alpine meadow, and the antagonistic activity, bacteriostatic hydrolase activity, and low temperature, salt, and drought resistance of it were determined and analysed. The seedlings of Avena sativa were root-irrigated using bacteria suspensions (cell concentration 1 × 107 cfu/mL) of GL18, and the growth-promoting effect of GL18 on it was determined under cold, salt and drought stress, respectively. The whole genome of GL18 was sequenced, and its functional genes were analysed. GL18 presented significant antagonistic activity to Fusarium graminearum, Fusarium acuminatum, Fusarium oxysporum and Aspergillus niger (inhibition zone diameter > 17 mm). Transparent zones formed on four hydrolase detection media, indicating that GL18 secreted cellulase, protease, pectinase and ß-1,3-glucanase. GL18 tolerated conditions of 10 °C, 11% NaCl and 15% PEG-6000, presenting cold, salt and drought resistance. GL18 improved the cold, salt and drought tolerance of A. sativa and it showed significant growth effects under different stress. The total length of the GL18 genome was 3,915,550 bp, and the number of coding DNA sequence was 3726. Compared with the clusters of orthologous groups of proteins, gene ontology and kyoto encyclopedia of genes and genomes databases, 3088, 2869 and 2357 functional genes were annotated, respectively. GL18 contained gene clusters related to antibacterial substances, functional genes related to the synthesis of plant growth-promoting substances, and encoding genes related to stress resistance. This study identified an excellent Bacillus strain and provided a theoretical basis for improving stress resistance and promoting the growth of herbages under abiotic stress.

Objective: To compare the prevalence of frailty and related factors in middle-aged and elderly people aged ≥45 years in island and mountainous areas of Taizhou, Zhejiang Province. Methods: Based on cross-sectional design, stratified cluster sampling and quota sampling methods were adopted. One administrative district was randomly selected from each of six coastal and three inland administrative districts in Taizhou during July to August, representing two different geographical terrains. In the island area (Jiaojiang District), all residents aged ≥45 years were included by cluster sampling. In the mountainous area (Xianju County), participants were selected through quota sampling, with same gender and age distributions. Data about their demographic characteristics, lifestyle and health-related factors were collected through questionnaire surveys and laboratory examinations. The prevalence of frailty was assessed using the Fried frailty phenotype scale. Hierarchical analysis and multivariate logistic regression analysis were used to compare the influencing factors of frailty. Results: A total of 1 011 local residents were studied, in whom island and mountainous residents accounted for 48.1% (486/1 011) and 51.9% (525/1 011) respectively; men and women accounted for 45.9% (464/1 011) and 54.1% (547/1 011) respectively. Middle-aged (45-49 years), younger elderly (60-74 years), and older elderly (≥75 years) residents accounted for 38.6% (390/1 011), 44.6% (451/1 011), and 16.8% (170/1 011) respectively. The overall prevalence rate of frailty was 3.6% (36/1 011), the prevalence rate was 3.7% (17/464) in men and 3.5% (19/547) in women. The prevalence rates in age groups 45-59,60-74 years and ≥75 years were 0.3% (1/390), 2.2% (10/451), and 14.7% (25/170), respectively. The prevalence rates of frailty and pre-frailty in island area were 6.0% (29/486) and 39.1% (190/486), respectively, which was higher than those in mountainous area (1.3%, 7/525) and (30.9%, 162/525). After adjusting for potential confounding factors, the risk for frailty in island residents was significantly higher than that in mountainous residents (aOR=1.55,95%CI: 1.07-2.25,P=0.019). In island area, older age (60-74 years:aOR=2.52,95%CI: 1.56-4.13; ≥75 years:aOR=11.65,95%CI:5.38-26.70), being women (aOR=1.94,95%CI: 1.20-3.17), suffering from depression (aOR=1.09,95%CI:1.02-1.17) were associated with frailty symptoms. In mountainous area, older age was also associated with an increased risk of frailty symptoms, but the OR value was lower than those in island area (60-74 years: aOR=1.74,95%CI:1.04-2.94;≥75 years: aOR=4.78,95%CI:2.45-9.50). Polydrug use (aOR=2.08,95%CI: 1.14-3.80) and suffering from depression (aOR=1.10,95%CI: 1.02-1.18) had significant positive association with frailty symptoms. Higher education level had significant negative association with frailty symptoms (junior high school: aOR=0.40,95%CI: 0.21-0.75; senior high school and technical secondary school: aOR=0.29,95%CI: 0.15-0.53; college or above:aOR=0.22,95%CI: 0.11-0.42). Conclusions: The prevalence of frailty in middle-aged and elderly community residents was significantly higher in island area than in mountainous area in Taizhou. The frailty-related factors varied with area. The elderly people (≥75 years) and women in island area had higher risk for frailty. Older age and suffering from depression were the independent risk factors for frailty. It is necessary to pay attention to the health risk factors and special environment in island area, and take comprehensive intervention measures to delay the process of debilitation and improve the quality of life of middle-aged and elderly people.

BACKGROUND: The surgical treatment of recurrent nasopharyngeal carcinoma (rNPC) involving the internal carotid artery (ICA) is challenging, as the massive bleeding caused by intraoperative rupture of the ICA is life-threatening. We reported that ICA embolization is an effective pretreatment to avoid fatal bleeding, but some patients cannot tolerate the procedure. We used endovascular vascular protection (ICA stents), vascular sacrifice (bypass grafting) and extravascular vascular protection (transcervical external stent placement) of the ICA to provide alternative options for these patients. METHODOLOGYy: This study enrolled patients with rNPC adjacent to or invading the ICA who were unsuitable for ICA embolization from January 2015 to June 2020. ICA pretreatment combined with endoscopic nasopharyngectomy (ENPG) was performed for the 30 patients. We report the survival outcome and incidence of complications after ICA pretreatment. RESULTS: ICA pretreatment was performed for the 30 enrolled patients, among whom 8 underwent endoscopic-assisted transcervical protection of the parapharyngeal ICA combined with ENPG, 6 underwent bypass grafting, and 16 underwent ICA stent implantation followed by ENPG. After pretreatment, at a median follow-up of 43 months (range, 2-80 months), the 3-year locoregional overall survival (OS), progression-free survival (PFS), locoregional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) were 62.9%, 61.3%, 70.2%, and 71.4%, respectively. CONCLUSIONS: ICA pretreatment combined with salvage ENPG enables the feasible and effective resection of rNPC lesions involving the ICA in patients who cannot tolerate ICA embolization. Therefore, this treatment may be an effective method for improving outcomes. Multidisciplinary therapy is needed to reduce operation-related complications.
RESUMO
OBJECTIVE: The c-Jun N-terminal kinases (JNK) signaling pathway may be involved in the regulation of osteoclast development. The purpose of this investigation was to investigate whether SB600125, a JNK inhibitor, could attenuate titanium-particle-induced inflammatory osteolysis in vivo. MATERIALS AND METHODS: A total of 45 mice were randomly divided into a Sham group, a Titanium group, and a Titanium + JNK inhibitor group, 15 mice per group. After establishing an air pouch bone graft model, we injected phosphate-buffered saline (PBS), titanium particles, or titanium particles + JNK inhibitor into the air pouch of the three groups. The pouch membranes containing bone implants were taken for morphological and molecular analysis 14 days after the mice were sacrificed. RESULTS: General morphological structure observation results, Hematoxylin and Eosin (H&E)-Stained Sections, anti-tartaric acid phosphatase (TRAP) staining, and the transmission electron microscope showed that SB600125, by inhibiting the expression of JNK, attenuated titanium particle-induced inflammatory osteolysis (p<0.05). Immunohistochemical appearance results and reverse transcription-polymerase chain reaction (RT-PCR) results showed SB600125 reduced expression of IL-6, and TNF-α in osteolytic sites stimulated with wear debris (p<0.05). The Western blot results showed the expression of the p-JNK protein in the titanium particle + SB600125 group was significantly reduced compared to the titanium particle stimulation group (p<0.05). CONCLUSIONS: Interfering with the JNK signaling pathway may be beneficial in reducing osteolysis, providing a therapeutic target for preventing and treating aseptic loosening caused by debris-induced inflammatory osteolysis.

Proliferative verrucous leukoplakia (PVL) is one of the oral potentially malignant disorders (OPMD) with the highest malignant potential. PVL tends to be easily misdiagnosed owing to the resemblance in clinical manifestations between PVL and other diseases such as oral leukoplakia or oral lichen planus. PVL is considered as a special type of oral leukoplakia by some scholars, which is characterized by its tendency of recurrence and metastasis, along with its high risk of malignant transformation. So far, the accurate clinic diagnosis and management of PVL are still intractable due to the lack of definite histopathological definition, unified diagnostic criteria and effective treatment modalities. This review aims to provide the clinical practitioners with a series of advices on the clinical diagnosis and management of PVL by systematically reviewing the diagnostic logistics, therapeutic strategies, malignant transformation detection based on tremendous relevant data and evidence-based medicine.

BACKGROUND: Post radiation nasopharyngeal necrosis (PRNN) invading the internal carotid artery (ICA) contributes to the death of 69.2-72.7% of PRNN patients. ICA occlusion is an effective treatment to avoid fatal bleeding, while some patients are intolerant. We present a novel method that allows for these patients without interrupting blood flow through the ICA. METHODOLOGY: This study enrolled patients with PRNN-invaded ICA who were not suitable for ICA occlusion from April 2020 to November 2022. ICA stent pretreatment was performed in the 36 patients and followed the endoscopic nasopharyngectomy (ENPG) or conservative treatment for PRNN. We report the survival outcome and incidence of complications after stent implantation and compare the survival outcomes of ENPG and conservative treatment for PRNN followed by stent implantation. RESULTS: ICA stent pretreatment was performed in the 36 enrolled patients, among which 14 underwent ENPG, and 22 received conservative treatment. 27.8% patients died after a median follow-up of 15 months. The Kaplan-Meier estimates of overall survival were higher in the ENPG group than in the conservative treatment group. Karnofsky performance status (KPS) was significantly higher in the ENPG group than in the non-ENPG group. CONCLUSIONS: The innovative application of ICA stents is a promising treatment to improve outcomes in patients with PRNN invading the ICA who are unsuitable for ICA embolization, especially when followed by endoscopic surgery. However, methods to avoid postoperative cerebral ischemia and nasopharyngeal hemorrhage still require further study.
RESUMO
PURPOSE: Prolactinoma is the most common type of pituitary adenoma. Most prolactinoma need medical treatment, but some of them are aggressive and require surgery. In previous decades, some miRNAs have been manifested as oncogenes or tumor suppressors. Consequently, miRNAs' abnormal expression involves tumorigenesis, invasion, and metastasis of different types of tumors, including pituitary tumors. The current study aim to explore the aggressiveness-associated miRNAs in prolactinoma and underlying molecular mechanisms based on the bioinformatic analysis and fundamental experiment studies. METHODS: GSE46294 miRNA expression profile from the Gene Expression Omnibus (GEO) database was downloaded. Differentially expressed miRNAs (DEMs) were filtered from this data. Subsequently, the target genes of downregulated miRNAs were analyzed by Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment. RT-qPCR, western blot, and CCK-8 assays were used to validate the effect of miR-137 on the proliferation of MMQ cells through AKT2. Finally, the binding site of rat miR-137 to AKT2 were predicted by Targetscan and Bibiserv database, and verified by double luciferase reporter assay. RESULTS: Twenty-four changed DEMs (fourteen upregulated and ten downregulated) were identified. Target genes of downregulated DEMs were classified into three groups by GO terms. KEGG pathway enrichment analysis revealed these target genes enriched in the PI3K-Akt pathway. We also confirmed that miR-137 can target AKT2 and inhibit the proliferation of MMQ cells induced by AKT2. CONCLUSION: MiR-137 suppressed prolactinomas' aggressive behavior by targeting AKT2.

Objective: To investigate the effect of continuous intravenous infusion of subanesthetic dose of esketamine intraoperatively on postoperative opioid consumption in patients undergoing thoracoscopic surgery. Methods: A total of 71 patients with elective thoracoscopic lung surgery in the First Affiliated Hospital of Zhengzhou University from December 2020 to December 2021 were selected. Patients who were classified as grade â or â ¡ by the American Society of Anesthesiologists (ASA) and aged 18-70 years were included, including 32 males and 39 females, with a body mass index (BMI) of 18.5-30.0 kg/m2. The patients were randomly divided into three groups: (1) Control group (group C, n=24): continuous intravenous infusion of normal saline at the same rate during surgery; (2) Subanesthetic dose of esketamine 0.125 mg·kg-1·h-1 group (group ES1, n=23): continuous intravenous infusion of esketamine at a rate of 0.125 mg·kg-1·h-1 during surgery; (3) Subanesthetic dose of esketamine 0.250 mg·kg-1·h-1 group (group ES2, n=24): continuous intravenous infusion of esketamine at a rate of 0.250 mg·kg-1·h-1 during surgery. The main outcome measures were the total consumptions of hydromorphone of 3 groups within 24 and 48 hours after surgery. The secondary outcome measures were the extubation time, length of postanesthesia care unit (PACU) stay, the time of first feeding, and the incidences of adverse effects within 24 h after surgery in 3 groups. Results: The 24 h postoperative consumption of hydromorphone in group C, ES1 and ES2 was (5.4±1.0) mg, (4.5±1.5) mg and (4.0±0.8) mg, respectively. Likewise, the 48 h postoperative consumption of hydromorphone was (9.7±2.2) mg, (9.0±3.0) mg and (7.7±1.8) mg, respectively. Compared with group C, the 24 h postoperative hydromorphone consumptions were significantly reduced in group ES1 and ES2 (both P<0.05). The extubation time, length of PACU stay and the time of first feeding after surgery in group C were (23±10) min,(70±12) min,(17±3) h,in group ES1 were (22±4) min,(69±11) min,(14±5) h,in group ES2 were (16±8) min,(58±12) min,(14±3) h, respectively. Compared with group C and group ES1, both of the extubation time and length of PACU stay were shortened in group ES2 (both P<0.05). Compared with group C, the first postoperative feeding time of group ES1 and ES2 was shortened (both P<0.05). There were no differences in the incidences of adverse effects at postoperative 24 h among 3 groups (all P>0.05). Conclusion: Continuously intravenous infusion of subanesthetic esketamine at a rate of 0.250 mg·kg-1·h-1 can significantly reduce the postoperative opioid consumption and improve the patient's outcomes.

The historical artifacts displayed in the Museum of Western study on Chinese Medicine at Yunnan University of Chinese Medicine came from a variety of Chinese medical schools in America and European countries. They are in the memorial galleries for some well-known figures, such as George Soulié de Morant (Su Lie), Jacques-André Lavier (La Wei Ai), Felix Mann (Man Fu Li) and Manfred Porkert (Man Xi Bo), representing the development and status of respective Chinese medical schools in America and European countries. The displayed artifacts are nearly 3,000 photos, manuscripts, documents and more than 500 hours of audiovisual materials, including instruments for acupuncture and moxibustion, books, passports, letters and even supplies for their life. The displayed artifacts demonstrate the process and the access of people in the western societies to know, learn and take use of Chinese medicine.

Objective: To discuss the techniques and repairing methods of various degree of compound tissue defects in the auriculotemporal region. Methods: Retrospective analysis was conducted on three cases of different repairing methods for huge compound tissue defects in different degrees in the auriculotemporal region after the resection of the malignant tumor or sinus tract due to repeated infection in our hospital. Results: Following total removal of the tumors or sinus tract in all patients, we applied retroauricular lingual flap transfer repairing, latissimus dorsi flap free transfer repairing and vascular anastomosis, scalp tissue expansion in stage â , then repairing the lesion with expanded scalp and filling the huge mastoid cavity with abdominal fat in stage â ¡, respectively, according to the characteristics of compound tissue defects in the auriculotemporal region. All free flaps survived well. Conclusions: The anatomy of the auricular-temporal area is complex and involves important vascular and neural structures of head and neck and lateral skull base. The huge composite tissue defect following auriculotemporal region surgery, which is composed of skin, muscle and bone tissue, needs to be repaired in one stage. Therefore, flexible repairing methods should be chosen based on different situations, for attaining the goal of completely removing tumor and lesions, and then, covering the operation cavity.

Objective: To investigate the clinicopathological features of pulmonary epithelioid hemangioendothelioma (PEHE). Methods: Eighteen cases of PEHE were collected from August 2011 to December 2018 at the First Affiliated Hospital of Zhengzhou University. All cases were retrospectively studied by hematoxylin and eosin staining and immunohistochemistry (IHC). The clinicopathological features were reviewed; the status of CAMTA1 and TFE3 gene was analyzed and patients' outcome was followed up. Results: Of the 18 cases, there were 11 males and 7 females with a male to female ratio of 1.6 to 1.0. The patients' age ranged from 36 to 68 years (mean 52 years). Twelve cases (12/18) showed a single nodule and six cases (6/18) showed multiple bilateral nodules. Seven cases (7/18) involved other organs besides lung. Seventeen (17/18) patients presented with respiratory symptoms and one patient (1/18) presented with abdominal pain. Grossly, the tumors were greyish-white nodules with indistinct borders. Microscopically the tumor cells were epithelioid and arranged in strands and nests, and cytoplasmic vacuoles were commonly noted. The stroma was myxochondroid or hyaline. By IHC, the tumor cells were positive for CD31(18/18), CD34 (16/18), ERG (18/18) and Fli-1 (18/18); CKpan was focally positive in 5 cases (5/18). TFE3 was positive in 3 cases (3/18), and Ki-67 index ranged from 5% to 30%. FISH analysis showed seventeen cases (17/18) had CAMAT1 rearrangement, one case had TFE3 rearrangement displaying a split signal. Eight patients (8/18) had surgical excision, three patients (3/18) had surgery and chemotherapy, and seven patients (7/18) had chemotherapy only. Four patients (4/18) died of the disease. Conclusions: Patients with PEHE have non-specific symptoms, and correct diagnosis depends on pathologic biopsy and the exclusion of other tumors with epithelioid morphology. Some patients with PEHE have poor prognosis, particularly in those who have multiple nodules, peripheral invasion or metastasis.

OBJECTIVE: In December 2019, a new type of coronavirus-infected pneumonia broke out in Wuhan and spread rapidly to other parts of the country. The purpose of this study was to investigate the clinical features of coronavirus disease 2019 (COVID-19). MATERIALS AND METHODS: A retrospective analysis was performed on the confirmed cases of COVID-19, who were admitted to the North Hospital of Changsha first Hospital (Changsha Public Health treatment Center) from January 17 to February 7, 2020. RESULTS: The median age of COVID-19 patients was 45 years (range 33.5-57). The male patients accounted for 49.7%, 64.6% of the patients had a history of exposure in Wuhan, and 31.7% had family aggregation. The median days of onset were six, and the incidence of severe illness was 18.6%. Compared with the non-severe group, the severe group showed statistical significance in older age, hypertension, bilateral lung plaque shadow, decrease in lymphocyte count, increase in C-reactive protein (CRP), aspartate aminotransferase (AST), lactate dehydrogenase, and creatine kinase. CONCLUSIONS: Age, combined hypertension, oxygenation index, double lung patch, decreased lymphocyte count, and elevated levels of C-reactive protein, aspartate aminotransferase, lactate dehydrogenase, and creatine kinase can be used as predictors of the disease severity.

Objective:To investigate the hemodynamic changes of internal jugular veinï¼IJVï¼ in patients with pulsatile tinnitusï¼PTï¼ detected by color doppler sonographyï¼CDSï¼. To explore the correlation of PT with IJV drainage dominance and the value of CDS in the diagnosis of PT. Method:Two hundred and twenty-one patients with PT were examined with the CDS and IJV compression test. The hemodynamic data of the upper, middle and lower IJV were compared with both PT side and unaffected side. The correlation of the PT with the IJV drainage dominance was analyzed. Result:A total of 125 casesï¼56.6%ï¼ of 221 patients with PT underwent ultrasonic IJV compression test with positive results, 96 casesï¼43.3%ï¼ with negative results. In the positive compression test group, the tinnitus disappeared after IJV being completely compressed in 109 casesï¼87.2%ï¼, and in 16 casesï¼12.8%ï¼ after IJV being partial closure. The extent of sectional area reduction was: upper jugular veinï¼75.41 ±9.39ï¼%, middle jugular veinï¼80.25±13.16ï¼%, lower jugular veinï¼86.58± 7.53ï¼%. The blood flow volume on the tinnitus side was obviously higher than that on the unaffected sideï¼P=0.001ï¼. In the negative compression test group, there was no significant difference in blood flow volume between tinnitus side and unaffected side. In the IJV positive compression test group, 54 casesï¼43.2%ï¼ were IJV drainage dominance combined, and 71 casesï¼56.8%ï¼ were non-dominant combined. In the IJV negative compression test group, 24 casesï¼25%ï¼ were IJV drainage dominance combined, and 72 casesï¼75%ï¼ were non-dominant combined. Conclusion:The positive result of IJV compression test using CDS and the flow volume of IJV on the affected side significantly higher than that on the unaffected side contributed to the diagnosis of venous PT. In this study, the IJV non-dominant side was more common in the venous PT.

BACKGROUND: Previous mass screening studies have shown that IgA antibodies against Epstein-Barr Virus (EBV) can facilitate early detection of nasopharyngeal carcinoma (NPC), but the impact of EBV-antibody screening for NPC-specific mortality remains unknown. PATIENTS AND METHODS: A prospective, cluster randomized, controlled trial for NPC screening (PRO-NPC-001) was conducted in 3 selected towns of Zhongshan City and 13 selected towns of Sihui City in southern China beginning in 2008. Serum samples of the screening group were tested for two previously selected anti-EBV antibodies. Subjects with serological medium risk were subsequently retested annually for 3 years, and those with serological high risk were referred to otorhinolaryngologists for diagnostic check-up. An interim analysis was carried out to evaluate the primary end points of the NPC-specific mortality and the early diagnostic rate, and the secondary end point of the NPC incidence, through linkage with the database of Zhongshan City. RESULTS: Among 70 296 total subjects, 29 413 screened participants (41.8% of the total subjects) in the screening group and 50 636 in the control group, 153 (43.3 per 100 000 person-year), 62 (55.3 per 100 000 person-year) and 99 (33.1 per 100 000 person-year) NPC cases were identified. The early diagnostic rates of NPC were significantly higher in the participants (79.0%, P < 0.0001) and the screening group (45.9%, P < 0.0001) compared with the control group (20.6%). Although no differences were found between NPC-specific mortality of the screening group and the control group [relative risk (RR)= 0.82, 95% confidence interval (CI) 0.37-1.79], lower NPC-specific mortality was noticed among participants from the screening group versus the control group (RR = 0.22, 95% CI 0.09-0.49). CONCLUSION: IgA antibodies against EBV can identify high-risk population and was effective in screening for early asymptomatic NPC. Although the mortality reduction was not significant in the primary end point, we noted encouraging evidence of a mortality reduction in screening participants in this interim analysis. CLINICAL TRIAL NUMBER: NCT00941538.

Objective: To investigate the clinical symptoms, imaging features, pathologic manifestations and diagnosis of tracheobronchopathia osteochondroplastica (TO). Methods: The clinical data, imaging and pathologic features and outcome of 18 TO patients diagnosed at the First Affiliated Hospital of Zhengzhou University from August 2011 to August 2018 were collected and analyzed. Results: The 18 TO patients included 10 males and 8 females; patients' age range was 31 to 64 years (mean 52 years). Six patients (6/18) were smokers. The main presenting clinical symptoms included cough in 15 cases, expectoration in eight cases (8/18), hemoptysis in five cases (5/18), chest tightness in four cases, wheezing in three cases and chest pain in two cases. The time interval between the initial symptoms and diagnosis was 1.5 to 360.0 months, and the average time interval was 45.2 months. Blood calcium and phosphorus were normal in 18 patients (18/18). Chest X-ray showed no direct evidence of TO. Six patients (6/18) showed irregular changes in the trachea or bronchial wall by chest CT scan. Three patients (3/18) had mild ventilatory obstruction. TO was classified as: 10 cases (10/18) were scattered type, seven cases (7/18) were diffuse type and one case (1/18) was confluent type. Epithelial squamous metaplasia, submucosal cartilage, submucosal ossification and hematopoietic bone marrow within the ossified areas were the characteristic histopathologic findings of TO. Conclusions: TO is a rare benign disorder that shows atypical presentation. CT scan is insensitive, the histopathology shows submucosal cartilage or ossification. TO should be diagnosed by comprehensive consideration of clinical symptoms, imaging and pathology.
