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.

Ischemic stroke (IS) is a globally life-threatening disease. Presently, few therapeutic medicines are available for treating IS, and rt-PA is the only drug approved by the US Food and Drug Administration (FDA) in the US. In fact, many agents showing excellent neuroprotection but no blood flow-improving activity in animals have not achieved ideal clinical efficacy, while thrombolytic drugs only improving blood flow without neuroprotection have limited their wider application. To address these challenges and meet the huge unmet clinical need, we have designed and identified a novel compound AAPB with dual effects of neuroprotection and cerebral blood flow improvement. AAPB significantly reduced cerebral infarction and neural function deficit in tMCAO rats, pMCAO rats, and IS rhesus monkeys, as well as displayed exceptional safety profiles and excellent pharmacokinetic properties in rats and dogs. AAPB has now entered phase I of clinical trials fighting IS in China.

Objective: To identify the spatio-temporal clustering analysis of mumps in Wenzhou City, Zhejiang Province from 2010 to 2023, so as to provide the basis for improving mumps prevention and control strategies. Methods: Data of mumps cases in Wenzhou City from 2010 to 2023 were collected from the Monitoring and Reporting Management System of Chinese Disease Prevention and Control Information System. The spatio-temporal clustering characteristics of mumps incidence were identified using spatial autocorrelation analysis and spatio-temporal scan analysis. Results: A total of 20 455 mumps cases were reported in Wenzhou City from 2010 to 2023, with an average annual incidence of 17.54/105. There were 12 919 male and 7 536 female cases, with a male-to-female ratio of 1.71∶1. The children aged 5-<10 years had the highest incidence of mumps at 135.29/105. The incidence of mumps showed a downward trend from 46.82/105 in 2010 to 3.59/105 in 2023 (P<0.05). The incidence of mumps peaked from May to July and from November to January during 2010 and 2012, the winter peak became less evident after 2013, and no seasonal trends were observed after 2020. Spatial autocorrelation analysis showed there was a positive spatial correlation of mumps of other years, with the exception of 2018 (all Moran's I >0, all P<0.05). Lucheng District, Longwan District, Ouhai District, Cangnan County and Rui'an City were high-high clustering sites. Spatio-temporal scan analysis showed that the primary clustering area was centered in Nanbaixiang Street, Ouhai District, covering 50 towns (streets), with the clustering time from April 2010 to August 2013; the secondary clustering area was centered in Zaoxi Town, Cangnan County, covering 24 towns (streets), with the clustering time from January 2010 to June 2013. Conclusions The incidence of mumps in Wenzhou City from 2010 to 2023 showed a downward trend. The urban areas, Cangnan County and Rui'an City were the clustering areas.

Objective:To compare the outcomes between the arthroscopic en masse repair and the modified separate repair for type Ⅰ delaminated rotator cuff tears.Methods:This retrospective study analyzed the clinical data of 46 patients who had been treated for delaminated rotator cuff tears at Department of Sports Medicine, The Second People's Hospital of Fujian Province from January 2021 to January 2023. This cohort consisted of 15 males and 31 females, with an age of (58.2±9.0) years. Their delaminated rotator cuff tears were all classified as typeⅠ according to Choo et al. According to different surgical methods, they were divided into 2 groups: group A (22 cases) was treated by arthroscopic en masse repair while group B (24 cases) by arthroscopic modified separate repair. The 2 groups were compared in terms of forward flexion, external rotation, internal rotation, visual analogue scale (VAS) for pain, American Shoulder and Elbow Surgeons (ASES) score, and Constant-Murley score at preoperation and the last follow-up. MRI was used to evaluate the healing status of rotator cuff at the last follow-up.Results:There was no significant difference in the baseline data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for 26.0 (24.0, 28.0) months. At the last follow-up, the external rotation (57.3°±15.7°), ASES score [(97.5±3.6) points] and Constant-Murley score [(93.7±3.0) points] in group B were significantly better than those in group A [40.9°±17.7°, (85.5±18.3) points, and (78.6±22.7) points] ( P<0.05), but the differences in forward flexion, internal rotation or VAS pain score were not significantly different between the 2 groups ( P>0.05). In both groups A and B, significant improvements were achieved at the last follow-up in forward flexion, external rotation, internal rotation, VAS pain score, ASES score, and Constant-Murley score compared with the preoperative period ( P<0.05). At the last follow-up, in group A and group B respectively, the rotator cuff was completely healed in 9 and 18 cases, partially healed in 10 and 6 cases, and re-torn in 3 and 0 cases, showing significant differences in the healing status between the 2 groups ( P<0.05). Conclusion:In the treatment of type Ⅰ delaminated rotator cuff tears, the modified separate repair can obtain significantly better external rotation, ASES score, Constant-Murley score, and healing status of rotator cuff than the arthroscopic en masse repair.

Objective:To investigate the incidence, clinical characteristics, and impact of spontaneous portosystemic shunt (SPSS) in patients with liver cirrhosis combined with hepatic encephalopathy (HE).Methods:The basic clinical and follow-up data were retrospectively analyzed for patients diagnosed with cirrhosis combined with HE at Mengchao Hepatobiliary Hospital of Fujian Medical University from January 2017 to December 2022. The patients were divided into large and small SPSS groups and a control group based on the results of abdominal enhanced CT or MRI.The clinical characteristics and outcome differences were compared among the three groups. Kaplan-Meier survival curves were used to compare HE-free survival time and overall survival time among the three groups. The log-rank test was used to compare the differences between groups. Cox regression analysis was used to identify the relevant risk factors affecting HE-free survival time and overall survival time.Results:A total of 223 cases with liver cirrhosis combined with HE were enrolled, including 150 in the SPSS and 73 in the control groups. The incidence rate of SPSS was 67.3% (150/223). The group was divided into small SPSS (79/150, 52.7%) and large SPSS group (71/150, 47.3%) according to the cross-sectional area of the diversion channel. The HE-free survival was shorter in the small and large SPSS groups compared with the control group (35.5 months in the small SPSS group and 21.3 months in the large SPSS group; P<0.001). The HE-free survival time was shorter in the large SPSS than with small SPSS group ( P=0.003). The overall survival time in the small SPSS group and the large SPSS group was shorter compared with the control group (small SPSS group: 39.4 months, large SPSS group: 52.9 months; P<0.001). There was no statistically significant difference in overall survival time between the small SPSS and large SPSS groups ( P=0.700). Cox regression analysis showed that SPSS was an independent risk factor affecting patients' HE-free survival time and overall survival time ( P<0.05). Conclusion:SPSS is more common in patients with liver cirrhosis combined with HE. Patients who combined with SPSS showed significant reductions in both HE-free survival time and overall survival time, especially evident in those with combined large SPSS.

Hepatic encephalopathy (HE) is a kind of neuropsychiatric syndrome caused by acute or chronic liver failure or portosystemic venous shunt (hereinafter referred to as portosystemic shunt), which can lead to the occurrence of functional impairment, personality and behavioral abnormalities, coma, and even death. Most patients with cirrhosis combined with HE have spontaneous portosystemic shunt (SPSS), especially those with recurrent or persistent HE. Internal medicine's current standard of treatment for HE associated with SPSS in cirrhotic patients is unsatisfactory, and even after treatment, recurrent HE episodes may still occur. Although interventional therapy has shown significant results and has been applied in clinical practice for many years for SPSS-associated HE, the number of treatment-related cases is relatively small, and there is a lack of large samples and well-designed research. Currently, interventional therapy for SPSS-associated HE in patients with cirrhosis is still under continuous exploration.

This study retrospectively analyzed data from 25 patients with paroxysmal nocturnal hemoglobinuria (PNH) admitted to Peking Union Medical College Hospital and Dongfang Hospital of Beijing University of Chinese Medicine from January 2023 to June 2024. Patients receiving sufficient eculizumab treatment for at least 3 months and who completed hemolytic complex (CH50) level testing pre- and post-treatment for 3 and 6 months were selected. Blood routine, biochemistry, and the 50% CH50-related indicators were monitored pre- and post-treatment. Among these patients, 24 completed 6 months of treatment and CH50 testing. After 3 and 6 months of eculizumab treatment, all patients with PNH showed significant improvement in symptoms, with lactate dehydrogenase (LDH) levels decreasing from a baseline of (1 814.4 ± 924.8) U/L to (248.5 ± 61.0) U/L and (239.3 ± 44.8) U/L. Hemoglobin levels increased from a baseline of (73.9±14.4) g/L to (99.9 ± 21.3) g/L and (99.6 ± 19.8) g/L. The baseline CH50 level was (32.4±14.7) %, which decreased to 2.0% (1.0% –8.0% ) and 1.0% (1.0% –4.0% ) at 3 and 6 months posttreatment, respectively. At baseline, a linear correlation was found between CH50 and LDH levels ( P<0.001), and the trend of CH50 changes was significantly lower than LDH at 3 and 6 months post-treatment with eculizumab, with similar trends. However, no linear correlation was observed between CH50 and LDH levels or other parameters at 3 and 6 months of medication. Our case demonstrates that eculizumab is effective for PNH hemolysis treatment. The serum CH50 level may be a biomarker for complement blockade induced by eculizumab, which can, to some extent, reflect the intravascular hemolysis of PNH and the efficacy of eculizumab.

Body weight abnormalities, including overweight, obesity, and underweight, have become a dual public health challenge in Chinese adults: overweight and obesity lead to a variety of chronic complications, while underweight increases the risks of malnutrition, sarcopenia, and organ dysfunction. To systematically address these issues, multidisciplinary experts in endocrinology, sports science, nutrition, and psychiatry from various regions have held multiple weight management seminars. Based on the latest epidemiological data and clinical evidence, they expanded the guideline to include assessment and intervention strategies for underweight, in addition to the core content of obesity management. This guideline outlines the etiological mechanisms, evaluation methods, and multidimensional management strategies for overweight and obesity, covering key areas such as diagnosis and assessment, medical nutrition therapy, exercise prescription, pharmacological intervention, and psychological support. It is intended to provide a scientific and standardized approach to weight management across the adult population, aiming to curb the rising prevalence of obesity, mitigate complications associated with abnormal body weight, and improve nutritional status and overall quality of life.

Paraganglioma（PGL）is an extra-adrenal catecholamine-secreting endocrine tumor. We reported a young female patient who was admitted to the hospital with right flank pain and diagnosed with right retroperitoneal PGL with Mayo Ⅳ inferior vena cava tumor thrombus（double tumor thrombus）. After multidisciplinary consultation，right retroperitoneal PGL resection，right nephrectomy，inferior vena cava Mayo Ⅳ tumor thrombus resection and reconstruction were performed. Postoperative pathology showed that the primary tumor and inferior vena cava tumor thrombus was consistent with PGL. Genetic testing revealed a heterozygous germline nonsense mutation at c.69_70delinsTT（p.Q24*）locus of the SDHB gene in the patient. His mother was a carrier of the gene，but his father and sister did not carry the mutation. The patient recovered smoothly after surgery.

This study aimed to explore the pharmacological mechanism of Yourenji Capsules(YRJ) in improving osteoporosis by combining network pharmacology and proteomics technologies. The SD rats were randomly divided into a blank control group and a 700 mg·kg~(-1) YRJ group. The rats were subjected to gavage administration with the corresponding drugs, and the blank serum, drug-containing serum, and YRJ samples were compared using ultra performance liquid chromatography-quadrupole time-of-flight tandem mass spectrometry(UPLC-Q-TOF-MS/MS) to analyze the main components absorbed into blood. Network pharmacology analysis was conducted based on the YRJ components absorbed into blood to obtain related targets of the components and target genes involved in osteoporosis, and Venn diagrams were used to identify the intersection of drug action targets and disease targets. The STRING database was used for protein-protein interaction(PPI) network analysis of potential target proteins to construct a PPI network. Gene Ontology(GO) functional enrichment and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment were performed using Enrichr to investigate the potential mechanism of action of YRJ. Ovariectomy(OVX) was performed to establish a rat model of osteoporosis, and the rats were divided into a sham group, a model group, and a 700 mg·kg~(-1) YRJ group. The rats were given the corresponding drugs by gavage. The femurs of the rats were subjected to label-free proteomics analysis to detect differentially expressed proteins, and GO functional enrichment and KEGG pathway enrichment analyses were performed on the differentially expressed proteins. With the help of network pharmacology and proteomics results, the mechanism by which YRJ improves osteoporosis was predicted. The analysis of the YRJ components absorbed into blood revealed 23 bioactive components of YRJ, and network pharmacology results indicated that key targets involved include tumor necrosis factor(TNF), tumor protein p53(TP53), protein kinase(AKT1), and matrix metalloproteinase 9(MMP9). These targets are mainly involved in osteoclast differentiation, estrogen signaling pathways, and nuclear factor-kappa B(NF-κB) signaling pathways. Additionally, the proteomics analysis highlighted important pathways such as peroxisome proliferator-activated receptor(PPAR) signaling pathways, mitogen-activated protein kinase(MAPK) signaling pathways, and β-alanine metabolism. The combined approaches of network pharmacology and proteomics have revealed that the mechanism by which YRJ improves osteoporosis may be closely related to the regulation of inflammation, osteoblast, and osteoclast metabolic pathways. The main pathways involved include the NF-κB signaling pathways, MAPK signaling pathways, and PPAR signaling pathways, among others.
