Oral squamous cell carcinoma (OSCC) is a common head and neck malignancy. Approximately 50% to 60% of patients with OSCC are diagnosed at a locally advanced stage (clinical staging III-IVa). Even with comprehensive and sequential treatment primarily based on surgery, the 5-year overall survival rate remains below 50%, and patients often suffer from postoperative functional impairments such as difficulties with speaking and swallowing. Programmed death receptor-1 (PD-1) inhibitors are increasingly used in the neoadjuvant treatment of locally advanced OSCC and have shown encouraging efficacy. However, clinical practice still faces key challenges, including the definition of indications, optimization of combination regimens, and standards for efficacy evaluation. Based on the latest research advances worldwide and the clinical experience of the expert group, this expert consensus systematically evaluates the application of PD-1 inhibitors in the neoadjuvant treatment of locally advanced OSCC, covering combination strategies, treatment cycles and surgical timing, efficacy assessment, use of biomarkers, management of special populations and immune related adverse events, principles for immunotherapy rechallenge, and function preservation strategies. After multiple rounds of panel discussion and through anonymous voting using the Delphi method, the following consensus statements have been formulated: 1) Neoadjuvant therapy with PD-1 inhibitors can be used preoperatively in patients with locally advanced OSCC. The preferred regimen is a PD-1 inhibitor combined with platinum based chemotherapy, administered for 2-3 cycles. 2) During the efficacy evaluation of neoadjuvant therapy, radiographic assessment should follow the dual criteria of Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1 and immune RECIST (iRECIST). After surgery, systematic pathological evaluation of both the primary lesion and regional lymph nodes is required. For combination chemotherapy regimens, PD-L1 expression and combined positive score need not be used as mandatory inclusion or exclusion criteria. 3) For special populations such as the elderly (≥ 70 years), individuals with stable HIV viral load, and carriers of chronic HBV/HCV, PD-1 inhibitors may be used cautiously under the guidance of a multidisciplinary team (MDT), with close monitoring for adverse events. 4) For patients with a poor response to neoadjuvant therapy, continuation of the original treatment regimen is not recommended; the subsequent treatment plan should be adjusted promptly after MDT assessment. Organ transplant recipients and patients with active autoimmune diseases are not recommended to receive neoadjuvant PD-1 inhibitor therapy due to the high risk of immune related activation. Rechallenge is generally not advised for patients who have experienced high risk immune related adverse events such as immune mediated myocarditis, neurotoxicity, or pneumonitis. 5) For patients with a good pathological response, individualized de escalation surgery and function preservation strategies can be explored. This consensus aims to promote the standardized, safe, and precise application of neoadjuvant PD-1 inhibitor strategies in the management of locally advanced OSCC patients.

ObjectiveTo investigate the mechanism of Zuogui Wan (ZGW) in improving ovarian inflammatory microenvironment and stemness of ovarian germline stem cells (OSCs) for treating ovarian aging via the cyclic guanosine monophosphate/adenosine monophosphate synthase (cGAS)/stimulator of interferon genes (STING) signaling pathway. MethodsForty C57BL/6 female mice were randomly divided into a blank group, a model group, a low-dose ZGW group (2.7 g·kg-1), a high-dose ZGW group (5.4 g·kg-1), and an estradiol valerate group (0.15 mg·kg-1), with 8 mice in each group. Except the blank group, all other groups received a single intraperitoneal injection of cyclophosphamide at 120 mg·kg-1 to establish an ovarian aging mouse model. After successful modeling, each group was continuously administered for 4 weeks, once daily. The physiological status of the mice was observed, and the ovarian index was calculated. The estrus cycle of the mice was monitored. Hematoxylin-eosin (HE) staining was used to observe pathological changes in ovarian tissue. Enzyme-linked immunosorbent assay (ELISA) was used to detect serum sex hormone levels. Serum inflammatory factors interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), and mouse interleukin-6 (IL-6) levels were detected using kits. Western blot was used to detect the protein expression of ovarian cGAS, STING, p-STING, TANK-binding kinase 1 (TBK1), p-TBK1, interferon-induced transmembrane protein 3 (Fragilis), and Vasa homolog protein (MVH). Quantitative real-time polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of inflammatory factors in ovarian tissue. Immunofluorescence double labeling was performed to locate OSCs in ovarian tissues, and fluorescence intensities of OSCs markers MVH and octamer binding transcription factor 4 (Oct4) were calculated. ResultsCompared with the blank group, the model group showed reduced body weight, ovarian wet weight, and ovarian index (P<0.01) and a disordered estrus cycle (P<0.01). In addition, the levels of serum follicle-stimulating hormone (FSH), TNF-α, IL-6, and IL-1β were increased (P<0.01), while anti-Müllerian hormone (AMH) and estradiol (E2) levels were decreased (P<0.01). The protein expression of cGAS, p-STING/STING, and p-TBK1/TBK1 in ovarian tissue was increased (P<0.05, P<0.01), while that of OSCs stemness factors MVH and Fragilis was reduced (P<0.01). Immunofluorescence indicated a reduction in MVH and Oct4 expression in OSCs (P<0.01). The mRNA expression of inflammatory factors TNF-α, IL-6, and IL-1β in ovarian tissue was increased (P<0.05, P<0.01). Compared with the model group, the treatment groups exhibited improved body weight, ovarian wet weight, and ovarian index (P<0.05) and a reduced rate of estrus cycle disorder (P<0.05, P<0.01). The levels of serum FSH, TNF-α, IL-6, and IL-1β were decreased (P<0.05, P<0.01), while AMH and E2 levels were increased (P<0.01). The protein expression levels of cGAS, p-STING/STING, and p-TBK1/TBK1 in ovarian tissue were decreased (P<0.05), while the protein expression of MVH and Fragilis was increased (P<0.05), and the fluorescence intensities of MVH and Oct4 were increased (P<0.05, P<0.01). The mRNA expression of inflammatory factors in ovarian tissue was decreased (P<0.05). ConclusionZGW alleviate ovarian inflammatory response, regulate ovarian microenvironment homeostasis, and maintain stemness of OSCs in ovarian aging mice probably by modulating the cGAS-STING signaling pathway, thereby improving ovarian function and delaying ovarian aging.

ObjectiveTo explore the therapeutic mechanism of Buchong Tiaojing prescription for rats with diminished ovarian reserve (DOR) from the perspectives of nucleotide-binding oligomerization domain (NOD)-like receptor protein 3 (NLRP3) inflammasome and ferroptosis. MethodsA total of 48 female SD rats were randomly divided into a normal group, a model group, low, medium, and high dose groups of Buchong Tiaojing prescription, and an MCC950 group, with eight rats in each group. Except the normal group, all the other groups were injected subcutaneously on the back of the neck with D-galactose to prepare the DOR rat model. From the 15th day of modeling, the rats in the low, medium, and high dose groups of Buchong Tiaojing prescription were subjected to gavage daily at doses of 14.4, 28.8, 57.6 g·kg-1, respectively. Rats in the MCC950 group were injected intraperitoneally with MCC950 at a dose of 10 mg·kg-1, once every other day. The interventions of all the groups lasted for 4 weeks. The estrous cycle of the rats was observed with vaginal exfoliated cell smear. Hematoxylin-eosin (HE) staining was performed to observe the development of follicles and corpus luteum in the ovary. Enzyme-linked immunosorbent assay (ELISA) was performed to detect the levels of serum sex hormones and interleukin-1β (IL-1β). Real-time fluorescence quantitative polymerase chain reaction (Real-time PCR) and Western blot assay were performed to detect the mRNA and protein expression of NLRP3 inflammasome, acyl-CoA synthetase long-chain family member 4 (ACSL4), transferrin receptor 1 (TFR1), and glutathione peroxidase 4 (GPX4), and oxidative stress kits were used to detect ovarian superoxide dismutase (SOD) and malondialdehyde (MDA) levels. ResultsDuring the experiment, one rat died in the high dose group of Buchong Tiaojing prescription, and a total of 47 rats were finally included in the index tests and statistics. Compared with those in the normal group, rats in the model group had significantly disturbed estrous cycles, increased number of atretic follicles, and significant disorder of serum sex hormones. The mRNA and protein expression of NLRP3 inflammasome, ACSL4, and TFR1 in ovarian tissue was up-regulated (P<0.01), while that of GPX4 was significantly down-regulated (P<0.01). The SOD content in the ovary was decreased significantly, while the MDA level was increased (P<0.01). After drug intervention, the estrous cycle of rats was basically resumed, and the follicles at all levels were more structurally intact and significantly increased in number. Additionally, the levels of serum sex hormones and IL-1β were significantly improved. The mRNA and protein expression of NLRP3 inflammasome, ACSL4, and TFR1 were down-regulated, while that of GPX4 was significantly up-regulated, and the ovarian oxidative stress was alleviated (P<0.05, P<0.01), especially in the high dose group of Buchong Tiaojing prescription and the MCC950 group. ConclusionInflammatory injury and ferroptosis occur in the ovaries of DOR rats, and the Buchong Tiaojing prescription is able to inhibit ovarian NLRP3 inflammasome, alleviate the degree of ovarian ferroptosis, and improve ovarian reserve.

Intraoperative cell salvage (IOCS) has been widely applied as an important blood conservation measure in surgical operations. However, there is currently a lack of clinical practice guidelines for the implementation of IOCS in patients with malignant tumors. This report aims to provide clinicians with recommendations on the use of IOCS in patients with malignant tumors based on the review and assessment of the existed evidence. Data were derived from databases such as PubMed, Embase, the Cochrane Library and Wanfang. The guideline development team formulated recommendations based on the quality of evidence, balance of benefits and harms, patient preferences, and health economic assessments. This study constructed seven major clinical questions. The main conclusions of this guideline are as follows: 1) Compared with no perioperative allogeneic blood transfusion (NPABT), perioperative allogeneic blood transfusion (PABT) leads to a more unfavorable prognosis in cancer patients (Recommended); 2) Compared with the transfusion of allogeneic blood or no transfusion, IOCS does not lead to a more unfavorable prognosis in cancer patients (Recommended); 3) The implementation of IOCS in cancer patients is economically feasible (Recommended); 4) Leukocyte depletion filters (LDF) should be used when implementing IOCS in cancer patients (Strongly Recommended); 5) Irradiation treatment of autologous blood to be reinfused can be used when implementing IOCS in cancer patients (Recommended); 6) A careful assessment of the condition of cancer patients (meeting indications and excluding contraindications) should be conducted before implementing IOCS (Strongly Recommended); 7) Informed consent from cancer patients should be obtained when implementing IOCS, with a thorough pre-assessment of the patient's condition and the likelihood of blood loss, adherence to standardized internally audited management procedures, meeting corresponding conditions, and obtaining corresponding qualifications (Recommended). In brief, current evidence indicates that IOCS can be implemented for some malignant tumor patients who need allogeneic blood transfusion after physician full evaluation, and LDF or irradiation should be used during the implementation process.

Objective To analyze the causes of HIV-2 specific bands in the Western blot (WB) tests and to understand previous HIV-2 infection status in this city. Methods A total of 68 samples with HIV-2 specific bands in WB were analyzed using two confirmatory reagents. The test results were further analyzed in combination with epidemiological data, nucleic acid testing and gene sequencing. Results When tested with MP reagent, 66 samples (97.06%) were found to be positive for HIV-2 antibody, while the other two were negative or undetermined for HIV-2 antibody. When tested with MIKROGEN reagent, 67 samples (98.53%) were found to be positive for HIV-1 antibody, and one sample was negative for HIV-1 antibody. Further HIV-1 nucleic acid testing was conducted on these samples, and all 68 samples tested positive for HIV-1 RNA, with the results all exceeding 5,000 copies/ml. After BLAST comparison, it was found that the homology similarity of 68 samples to the HIV-1 reference strain sequence was >90%, but there was no similarity with the HIV-2 reference strain sequence. Conclusion The results of the serological test, nucleic acid test and gene sequencing of the 68 samples all have indicated HIV-1 infection. Combined with the epidemiological data, it can be concluded that the double reaction of HIV-1 and HIV-2 antibodies in WB tests of these 68 samples is very likely to be a non-specific cross-reaction rather than HIV-2 infection. This study indicates that no HIV-2 infection cases have been found in Chengdu so far.

Objective To investigate the prevalence of Schistosoma japonicum infections in wild rodents in schistosomiasis-endemic areas of China, so as to provide insights into formulation of technical guidelines for monitoring of and the precise control strategy for S. japonicum infections in wild rodents during the elimination phase. Methods Two administrative villages where schistosomiasis was historically highly prevalent were selected each from Dongzhi County, Anhui Province, and Duchang County, Jiangxi Province as study villages. Wild rodents were captured from study villages with baited traps or cages at night in June and September, 2021. The number of rodents captured was recorded, and the rodent species was characterized based on morphologi-cal characteristics. Liver tissues were sampled from captured rodents for macroscopical observation of the presence of egg granu- lomas, and S. japonicum infection was detected simultaneously using liver tissue homogenate microscopy, examinations of mesenteric tissues for parasites, and modified Kato-Katz thick smear technique (Kato-Katz technique). A positive S. japonicum infection was defined as detection of S. japonicum eggs or adult worms by any of these methods. The rate of wild rodent capture and prevalence of S. japonicum infections in wild rodents were compared in different study villages and at different time periods, and the detection of S. japonicum infections in wild rodents was compared by different assays. Results The overall rate of wild ro- dent capture was 8.28% (237/2 861) in Dongzhi County, and the wild rodent capture rates were 9.24% (133/1 439) and 7.31% (104/1 422) in two study villages (χ2 = 3.503, P = 0.061), and were 8.59% (121/1 409) and 7.99% (116/1 452) in June and September, 2021, respectively (χ2 = 0.337, P = 0.561). The overall rate of wild rodent capture was 3.72% (77/2 072) in Duchang County, and the wild rodent capture rates were 6.91% (67/970) and 0.91% (10/1 102) in two study villages (χ2 = 51.901, P < 0.001), and were 4.13% (39/945) and 3.37% (38/1 127) in June and September, 2021, respectively (χ2 = 0.815, P = 0.365). Rattus norvegicus was the predominant rodent species captured in both counties, accounting for 70.04% (166/237) of all captured wild rodents in Dongzhi County and 88.31% (68/77) in Duchang County. No S. japonicum infection was detected in wild rodents captured in Duchang County. Nevertheless, the overall prevalence of S. japonicum infections was 51.05% (121/237) in wild rodents captured in Dongzhi County, with prevalence rates of 50.38% (67/133) and 51.92% (54/104) in two study villages (χ2 = 0.098, P = 0.755), and 54.31% (63/116) and 47.93% (58/121) in September and June, 2021, respectively (χ2 = 0.964, P = 0.326). Of 237 wild rodents captured in Dongzhi County, there were 140 (59.07%) rodents with visible hepatic egg granulomas, 117 (49.47%) tested positive for S. japonicum eggs by liver tissue homogenate microscopy, 34 (14.35%) tested positive for S. japonicum eggs with Kato-Katz technique; however, no adult S. japonicum worms were detected in mesenteric tissues. In addition, hepatic egg granulomas were found in all wild rodents tested positive for S. japonicum eggs with liver tissue homogenate microscopy. Conclusions The rate of wild rodent capture and prevalence of S. japonicum infection in wild rodents vary greatly in schistosomiasis-endemic areas of China, and the prevalence of S. japonicum infection is slightly higher in wild rodents captured in autumn than in summer. Liver tissue is recommended as the preferred sample for surveillance of S. japonicum infection in wild rodents, and a combination of macroscopical observation of hepatic egg granulomas and liver tissue homogenate microscopy may be a standard method for surveillance of S. japonicum infection in wild rodents.

OBJECTIVE:
To observe the effects of moxibustion at "Xinshu" (BL15) and "Feishu" (BL13) on myocardial transferrin receptor 1 (TfR1), ferroptosis suppressor protein 1 (FSP1), atrial natriuretic peptide (ANP), and typeⅠcollagen myocardial collagen fibers (CollagenⅠ) in rats with chronic heart failure (CHF), and to explore the mechanism of moxibustion for ameliorating myocardial fibrosis and improving cardiac function in CHF.
METHODS:
Fifty SD rats were randomly divided into a normal group (n=10) and a modeling group (n=40). The CHF model was established in the modeling group by ligating the left anterior descending coronary artery. After successful modeling, the rats were randomly divided into a model group (n=9), a moxibustion group (n=8), a rapamycin (RAPA) group (n=9), and a moxibustion+RAPA group (n=9). In the moxibustion group, moxibustion was delivered at bilateral "Feishu"(BL13) and "Xinshu" (BL15), 15 min at each point in each intervention, once daily, for 4 consecutive weeks. In the RAPA group, RAPA solution was administered intraperitoneally at a dose of 1 mg/kg, once daily for 4 consecutive weeks. In the moxibustion+RAPA group, RAPA solution was administered intraperitoneally after moxibustion. Ejection fraction (EF) and left ventricular fractional shortening (FS) were measured after modeling and intervention. After intervention, morphology of cardiac muscle was observed using HE staining and Masson's trichrome staining. Total iron content in myocardial tissue was detected using a colorimetric method. Western blot and qPCR were adopted to detect the protein and mRNA expression of TfR1, FSP1, ANP, and CollagenⅠ in myocardial tissue.
RESULTS:
Compared with the normal group, the EF and FS values decreased (P<0.01); necrosis, edema, degeneration, and arrangement disorder were presented in cardiomyocytes; inflammatory cells were obviously infiltrated, the structure of myocardial fibers was disarranged, the collagen fibers were obviously deposited and fibrosis increased (P<0.01); the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue were elevated (P<0.01), while the protein and mRNA expression of FSP1 were reduced (P<0.01) in the model group. Compared with the model group, the moxibustion group showed that EF and FS increased (P<0.01); myocardial cell morphology was improved, and myocardial fibrosis was alleviated (P<0.01); the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue decreased (P<0.01), while the protein and mRNA expression of FSP1 increased (P<0.01, P<0.05). Compared with the model group, the myocardial fibrosis was increased (P<0.05); the total iron content and the protein and mRNA expression of TfR1, ANP, CollagenⅠ in myocardial tissue were increased (P<0.01), while protein and mRNA expression of FSP1 decreased (P<0.01) in the RAPA group. When compared with the RAPA group and the moxibustion + RAPA group, EF and FS were elevated (P<0.01, P<0.05); myocardial cells were improved in morphology, the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue decreased (P<0.01), while protein and mRNA expression of FSP1 increased (P<0.01) in the moxibustion group. In comparison with the moxibustion + RAPA group, the RAPA group showed the decrease in EF and FS (P<0.01), the worsened myocardial fibrosis (P<0.01), the increase in the total iron content and the protein and mRNA expression of TfR1, ANP, and CollagenⅠ in myocardial tissue (P<0.01), and the decrease in the protein and mRNA expression of FSP1 (P<0.01).
CONCLUSION
Moxibustion at "Feishu" (BL13) and "Xinshu" (BL15) can slow down the process of myocardial fibrosis and improve cardiac function in CHF rats. The mechanism of moxibustion may be related to inhibiting ferroptosis through regulating autophagy.

OBJECTIVE:
To observe the effect of moxibustion on small intestinal mucosal immune barrier in rats with diarrhea-predominant irritable bowel syndrome (IBS-D) and explore its underlying mechanisms.
METHODS:
Of 38 newborn rats from 4 healthy SPF pregnant rats, 12 neonatal rats were randomly selected in a normal group. IBS-D model was prepared by the combined measures for the rest rats, including neonatal maternal separation, acetic acid enema and chronic restraint stress. Twenty-four successfully-modeled rats were randomized into a model group and a moxibustion group, 12 rats in each one. In the moxibustion group, suspending moxibustion was delivered at bilateral "Tianshu" (ST25) and "Shangjuxu" (ST37), 20 min each time, once daily and for 7 consecutive days. Separately, before acetic acid enema (aged 35 days), after modeling (aged 45 days) and after intervention (aged 53 days), the body mass, loose stool rate (LSR) and and the minimum volume threshold when abdominal withdrawal reflex (AWR) scored 3 were observed in the rats of each group. After intervention (aged 53 days), using HE and PAS staining, the morphology of duodenum was observed, the length of villus and the depth of crypt were measured, the ratio of the length of villus to the depth of crypt was calculated; and the numbers of mucosal intraepithelial lymphocytes (IELs) and goblet cells were counted. With ELISA adopted, the contents of γ-interferon (IFN-γ), interleukin-4 (IL-4) and secretory immunoglobulin A (sIgA) in duodenal mucosa of rats were detected. The proportion of T cell subsets in duodenal mucosa was detected using flow cytometry. The microvilli and tight junctions of duodenal mucosal epithelial cells were observed by transmission electron microscopy, and the integrity of duodenal mucosa observed by scanning electron microscopy.
RESULTS:
Compared with the normal group, for the rats in the model group, the body mass, the minimum volume threshold when AWR scored 3, the length of duodenal villus and the the ratio of the length of villus to the depth of crypt, as well as the proportion of CD8+ T subset were all reduced (P<0.01, P<0.05), the counts of goblet cells in duodenal mucosa decreased (P<0.01); LRS, the proportion of CD4+ T subset and CD4+/CD8+, as well as the contents of IFN-γ, IL-4 and sIgA in duodenal mucosa and IFN-γ/IL-4 were all elevated (P<0.01); and the numbers of IELs rose (P<0.01). The morphology of duodenal mucosa was irregular, the villi got shorter, sparse and scattered, with uneven density. The morphology of epithelial cells was destroyed and the tight junctions damaged, with larger spaces. When compared with the model group, in the moxibustion group, the body mass, the minimum volume threshold when AWR scored 3, the length of duodenal villus and the ratio of the length of villus to the depth of crypt, as well as the counts of goblet cells in duodenal mucosa increased (P<0.01); LRS, the proportion of CD4+ T subset, and CD4+/CD8+, as well as the contents of IFN-γ, IL-4 and sIgA in duodenal mucosa and IFN-γ/IL-4 were reduced (P<0.01); and the numbers of IELs was dropped (P<0.01). The morphology of duodenal mucosa was more regular, the villi were grew, got longer and arranged regularly, with even density. The morphology of epithelial cells was slightly destroyed, and the tight junctions partially damaged.
CONCLUSION
Moxibustion at "Tianshu" (ST25) and "Shangjuxu" (ST37) can reduce visceral hypersensitivity in IBS-D rats and relieve abdominal pain, diarrhea and other symptoms. Its effect mechanism may be related to the repair of small intestinal mucosal immune barrier and the improvement in the immune function in IBS-D.
