By selecting stable and detectable drug prototypes or metabolites in sewage samples, near real-time detection of disease conditions can be achieved. This study selected oseltamivir carboxylate, the primary metabolite of first-line antiviral oseltamivir, as a biomarker. Based on the concentration of oseltamivir carboxylate in wastewater, the consumption and usage rate of oseltamivir were calculated by reverse engineering. Quarterly sampling was conducted at 46 urban sewage treatment plants in representative 5 cities in the middle and lower reaches of the Yangtze River, from November 2022 to December 2023. The concentration range of oseltamivir acid in sewage samples is 1.270−1 279 ng/L, the daily mass load of oseltamivir per 1 000 inhabitants in the surveyed cities ranged from 9.560 to 544.7 mg/d, and the average utilization rate is 0.06‰−3.63‰. The research results indicate that in March 2023, Wuxi City experienced a spring influenza peak, while Bengbu, Tongling, Suzhou, and Changzhou City experienced a small summer influenza peak in May. In November and December 2023, Wuxi, Changzhou, and Bengbu City experienced a winter influenza peak, the results are consistent with the official statistics of the National Center for Disease Control and Prevention and the National Influenza Center, which reflect the influenza epidemic situation in southern cities. The integration of this methodology with clinical diagnostic rates could provide near real-time data support for future influenza prevention and control strategies.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Background:Super-responders (SRs) to cardiac resynchronization therapy (CRT) regain near-normal or normal cardiac function.The extent of cardiac synchrony of SRs and whether continuous biventricular (BIV) pacing is needed remain unknown.The aim of this study was to evaluate the cardiac electrical and mechanical synchrony of SRs.Methods:We retrospectively analyzed CRT recipients between 2008 and 2016 in 2 centers to identify SRs,whose left ventricular (LV) ejection fraction was increased to ≥50％ at follow-up.Cardiac synchrony was evaluated in intrinsic and BIV-paced rhythms.Electrical synchrony was estimated by QRS duration and LV mechanical synchrony by single-photon emission computed tomography myocardial perfusion imaging.Results:Seventeen SRs were included with LV ejection fraction increased from 33.0 ± 4.6％ to 59.3 ± 6.3％.The intrinsic QRS duration after super-response was 148.8 ± 30.0 ms,significantly shorter than baseline (174.8 ± 11.9 ms,P =0.004,t=-3.379) but longer than BIV-paced level (135.5 ± 16.7 ms,P =0.042,t =2.211).Intrinsic LV mechanical synchrony significantly improved after super-response (phase standard deviation [PSD],51.1 ± 16.5° vs.19.8 ± 8.1°,P ＜ 0.001,t =5.726;phase histogram bandwidth (PHB),171.7±64.2° vs.60.5 ±22.9°,P＜ 0.001,t=5.376) but was inferior to BIV-paced synchrony (PSD,19.8 ± 8.1° vs.15.2 ± 6.4°,P =0.005,t =3.414;PHB,60.5 ± 22.9° vs.46.0 ± 16.3°,P =0.009,t =3.136).Condusions:SRs had significant improvements in cardiac electrical and LV mechanical synchrony.Since intrinsic synchrony of SRs was still inferior to BIV-paced rhythm,continued BIV pacing is needed to maintain longstanding and synchronized contraction.

OBJECTIVE: To explore the role of γδT cells against bladder cancer and to detect the expression of stress proteins MICA/B recognized by γδT cells in bladder cancer. METHODS: γδT cells from peripheral blood drawn from 6 bladder cancer patients with pamidronate stimulating were expanded. Flow cytometry was used to detect the purity and expansion folds of γδT cells, and the expression of CD107a on γδT cells after PMA/ionomycin stimulated. The cytotoxicity assay was carried out to test the cytotoxicity of γδT cells against human bladder cancer cell lines. The expression of MICA/B on bladder cancer cell lines and in bladder cancer tissues were detected through flow cytometry and immunohistochemistry respectively. RESULTS: γδT cells from peripheral blood drawn from 6 bladder cancer patients were successfully expanded. The purity was 75%-94% and the expansion folds were 109-371 times. After being stimulated by PMA/ionomycin, the proportion of CD107a+ γδT cells increased significantly, reaching 40%-82%. γδT cells from the 6 bladder cancer patients showed obvious cytotoxic effects on 3 human bladder cancer cell lines which was enhanced as the effector: the target ratio increased. MICA/B were detected both in 3 bladder cancer cell lines and in 26 bladder cancer tissues. The staining score of MICA/B in invasive bladder cancer was slightly higher than that in non-invasive bladder cancer, and in advanced bladder cancer was higher than that in low grade bladder cancer, but the statistical analysis showed that the staining score of MICA/B was no significant correlation between the tissue and the tumor stages and grades. CONCLUSION γδT cells from the peripheral blood of the bladder cancer patients could be successfully expanded in vitro, and showed significant anti-bladder cancer effect. MICA/B were detected both in bladder cancer cell lines and in bladder cancer tissues. The statistical analysis showed that there was no significant correlation between the staining scores of MICA/B in the tissue and the tumor stages and grades.

BACKGROUNDUnderstanding the characteristics of Chinese dialysis patients and the current practice trends is the first step to evaluate the association between practice pattern and outcome in these populations. In the present study, we evaluated the status of medical treatment and characteristic features of chronic dialysis patients in China.

METHODSThrough a clustering sampling, we selected 9 centers from the largest dialysis facilities in 6 cities around China. All adult undergoing dialysis in the selected units were screened. A total of 2388 (1775 on hemodialysis (HD) and 613 on peritoneal dialysis (PD)) patients were finally enrolled. All data were collected at enrollment on the bases of review of medical records.

RESULTSIn this cohort, 1313 (55.0%) were male. The mean age was 54 years old. The median time for dialysis was 26 months (12 - 51 months). Seventy-five percent of patients were on HD and 25.0% on PD. Among PD patients, about 21% patients did not receive dialysis adequacy. For HD patients, about 14.0% of them did not achieve dialysis adequacy when the target of kt/V was set as 1.2. Only 44.7% of patients achieved blood pressure target of 140/90 mmHg. About 60% of patients did not reach the hemoglobin target of 110 g/L even though 85.0% of them were treated with erythropoietin. In addition, 48.5% of the patients had uncontrolled mineral metabolism revealed by the high calcium-phosphate product. Compared with HD patients, higher level of serum glucose, triglyceride, and total and low density lipoprotein cholesterol were more common in PD patients.

CONCLUSIONSThis observational study suggests that many Chinese dialysis patients did not achieve the therapeutic target, particularly in blood pressure control, anemia correction, and mineral balance. PD patients were more likely to suffer metabolic disturbance.
