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.

BACKGROUND:The occurrence and development of various ophthalmic diseases are closely related to excessive oxidative stress,and the inhibition of oxidative stress response may produce preventive and therapeutic effects. OBJECTIVE:To explore the role of Pax6 gene expression on hydrogen peroxide-induced aging of mouse bone marrow mesenchymal stem cells(BM-MSCs). METHODS:Resuscitated BM-MSCs,Pax6/BM-MSCs,and shPax6/BM-MSCs were treated with hydrogen peroxide for 24 hours,and then β-galactosidase staining was performed.The proliferation index Ki67 expression and apoptosis were detected by flow cytometry.The expression of senescence-associated molecules(Wnt7a,p21,and p53)was detected by RT-PCR. RESULTS AND CONCLUSION:(1)After hydrogen peroxide treatment,the cells of the three groups showed senescence phenotype and β-galactosidase staining was positive.Compared with BM-MSCs group,the expression of positive cells in Pax6/BM-MSCs group was less and that in the shPax6/BM-MSCs group was more,and the difference was statistically significant(P<0.05).(2)The results of flow cytometry showed that compared with BM-MSCs group,the positive expression of Ki67 in the Pax6/BM-MSCs group increased and the level of apoptosis decreased,while the positive expression of Ki67 decreased and the level of apoptosis increased in the shPax6/BM-MSCs group;the difference was significantly different(P<0.05).(3)RT-PCR showed that compared with the BM-MSCs group,the expression of Wnt7a,p53,and p21 decreased in the Pax6/BM-MSCs group,while the expression of Wnt7a,p53,and p21 increased in the shPax6/BM-MSCs group;the difference was significantly different(P<0.05).(4)These findings indicate that overexpression of Pax6 can antagonize the aging progression of BM-MSCs induced by hydrogen peroxide,which may be related to Wnt signaling pathway.

Objective To explore the effect of applying comprehensive interventions on promoting pathogen detec-tion before antimicrobial therapy in hospitalized patients.Methods Hospitalized patients who received therapeutic use of antimicrobial agents in a tertiary first-class hospital from January 2020 to December 2021 were selected as the research subjects.Comprehensive intervention measures were implemented from January 2021.The pathogen detec-tion rates,detection classification,and detection rates of key monitored departments before antimicrobial therapy were compared between the pre-intervention group(January-December 2020)and the post-intervention group(Janu-ary-December 2021).Results A total of 10 239 hospitalized patients who received therapeutic use of antimicrobial agents were included in analysis,4 526 cases were in the pre-intervention group and 5 713 cases in the post-interven-tion group.The pathogen detection rates before antimicrobial therapy,before restricted grade antimicrobial therapy,and before special grade antimicrobial therapy after intervention were 94.56％,94.72％,and 96.03％,respective-ly,which were higher than 83.74％,84.47％,and 84.95％before intervention,with statistical significance(all P＜0.05).The detection rate of targeted pathogens after intervention was 64.87％,higher than that before interven-tion(28.04％),with statistically significant difference(P＜0.05).The pathogen detection rates before therapeutic use of antimicrobial agents in departments of critical care medicine,pulmonary and critical care medicine,pediatrics,neurosurgery,and general surgery after intervention were 93.20％,91.17％,92.20％,94.12％,and 91.15％,re-spectively,higher than the rates before intervention,namely 85.00％,82.19％,83.20％,83.33％,and 83.03％,respectively,with statistical significance(all P＜0.05).Conclusion The application of comprehensive intervention measures can improve the pathogen detection rate before antimicrobial therapy of hospitalized patients.Close atten-tion should be paid to the pathogen detection indicators related to healthcare-associated infection diagnosis and for the detection of sterile body fluid.

Aim To explore the mechanism of process¬ing and increasing efficiency of Arisaematis rhizomz preparatum. Methods UPLC-Q-TOF-MS/MS tech¬nology was used to detect the chemical components be¬fore and after processing of Arisaematis rhizomz prepara¬tum, and its mechanism of action was analysed in the treatment of 44 asthma and phlegm " by using network pharmacology. A rat model of allergic asthma was es- tablished to compare the efficacy of Arisaematis rliizoma before and after processing. Results A total of 27 chemical components were identified, among which cur- cumin ,6-gingerol and other components increased after processing. Combined with the database prediction, the action mechanism of the 36 chemical components in the treatment of 44 asthma and phlegm" diseases was dis¬cussed and predicted through network pharmacology. The results of animal experiments showed that the effect of processed Arisaematis rhizoma on allergic asth¬ma was better than that of Arisaematis rhizoma, but there was no significant difference. Conclusions The addition of curcumin, 6-gingerol, camphor, demethyl- curcumin and other components after the processed Ari¬saematis rhizomz preparatum may be the reason for the synergistic effect of Arisaematis rhizomz preparatum in the treatment of allergic asthma.

Objective: To analyze the risk factors for complications of endoscopic full-thickness resection (EFTR) of upper gastrointestinal submucosal tumors (SMTs). Methods: This was a retrospective observational study. The indications for EFTR included: (1) SMTs originating from the muscularis propria layer and growing out of the cavity or infiltrating the deep part of the muscularis propria layer; (2) SMTs diameter <5 cm; and (3) tumor identified as closely adherent to the serous layer during endoscopic submucosal dissection or endoscopic mucosal resection. This study included patients with SMTs originating from the muscularis propria layer in upper digestive tract, diagnosed preoperatively by endoscopic ultrasonography or computed tomography, who were successfully treated with EFTR. Those with incomplete clinical data were excluded. The clinical data of 154 patients with upper gastrointestinal SMTs who underwent EFTR at the Department of Gastroenterology, First Affiliated Hospital of Soochow University from January 2016 to January 2022 were retrospectively analyzed. Post-EFTR complications (such as delayed perforation, delayed bleeding, and postoperative infection, including electrocoagulation syndrome) were monitored and the risk factors for them were analyzed. Results: Among the 154 study patients, 33 (21.4%) developed complications, including delayed bleeding in three (1.9%), delayed perforation in two (1.3%), and postoperative infection in 28 (18.2%). One patient with bleeding was classified as having a major complication (hospitalized for more than 10 days because of complication). According to univariate analysis, complication was associated with tumor diameter >15 mm, operation time >90 minutes, defect closure method(purse string suture), and diameter of resected specimen ≥20 mm (all P<0.05). Multivariate logistic regression analysis showed that operation time >90 minutes (OR=6.252, 95%CI: 2.530-15.446, P<0.001) and tumor diameter >15 mm (OR=4.843, 95%CI: 1.985-11.817, P=0.001) were independent risk factors for complications after EFTR in patients with upper gastrointestinal SMTs. The independent risk factors for postoperative infection in these patients were operation time>90 minutes (OR=4.993, 95%CI:1.964-12.694, P=0.001) and purse string suture (OR=7.142, 95%CI: 1.953-26.123, P=0.003). Conclusion: Patients with upper gastrointestinal SMTs undergoing EFTR with tumor diameter >15 mm or operation time >90 minutes have a significantly increased risk of postoperative complications. Postoperative monitoring is important for these patients with SMTs.

OBJECTIVES: To investigate the incidence of extrauterine growth retardation (EUGR) and its risk factors in very preterm infants (VPIs) during hospitalization in China. METHODS: A prospective multicenter study was performed on the medical data of 2 514 VPIs who were hospitalized in the department of neonatology in 28 hospitals from 7 areas of China between September 2019 and December 2020. According to the presence or absence of EUGR based on the evaluation of body weight at the corrected gestational age of 36 weeks or at discharge, the VPIs were classified to two groups: EUGR group (n=1 189) and non-EUGR (n=1 325). The clinical features were compared between the two groups, and the incidence of EUGR and risk factors for EUGR were examined. RESULTS: The incidence of EUGR was 47.30% (1 189/2 514) evaluated by weight. The multivariate logistic regression analysis showed that higher weight growth velocity after regaining birth weight and higher cumulative calorie intake during the first week of hospitalization were protective factors against EUGR (P<0.05), while small-for-gestational-age birth, prolonged time to the initiation of total enteral feeding, prolonged cumulative fasting time, lower breast milk intake before starting human milk fortifiers, prolonged time to the initiation of full fortified feeding, and moderate-to-severe bronchopulmonary dysplasia were risk factors for EUGR (P<0.05). CONCLUSIONS It is crucial to reduce the incidence of EUGR by achieving total enteral feeding as early as possible, strengthening breastfeeding, increasing calorie intake in the first week after birth, improving the velocity of weight gain, and preventing moderate-severe bronchopulmonary dysplasia in VPIs.

The chigger mite Leptotrombidium sialkotense is one of the 6 main vectors of scrub typhus in China. Before present study, L. sialkotense was found in some parts of Hunan province, China with a narrow geographical distribution. During field investigation 2016-2017, we found L. sialkotense in Jingha, southern Yunnan, China. Of 15 small mammal host species, L. sialkotense were collected from 6 species of the hosts. Rattus brunneusculus was a dominant host of L. sialkotense, from which 98.3% of the mites were collected. The chigger mite showed a relatively high infestation prevalence (PM=11.7%) and mean abundance (MA=0.5) in comparison with the rest 5 host species. These results reveal a certain host specificity of L. sialkotense to a rat R. brunneusculus. The mite L. sialkotense showed an aggregated distribution on the host (P<0.05). A positive correlation observed between L. sialkotense and the body length of hosts. There was a positive interspecific association between L. sialkotense and 2 other dominant vectors, L. deliense and L. scutellare.

To evaluate the clinical efficacy and safety of tripterygium glycosides (TG) in the treatment of henoch-schonlein purpura nephritis(HSPN). Seven English and Chinese databases (up to Nov. 9, 2017), were searched to collect the RCTs on TG for HSPN. Two researchers independently screened the literature according to inclusion criteria and exclusion criteria, extracted data, and evaluated the quality of the literature. After completion, cross-checking was performed and Meta-analysis was performed using RevMan 5.3 software. At the same time, different outcomes of the interventions were analyzed subgroupically. A total of 46 RCTs were included, with 1 659 in the experimental group and 1 596 in the control group. All the clinical studies showed a low quality. In terms of complete remission rate, the group with TG performed better than the group with conventional therapy or GC（RR=1.82，95%CI[1.39，2.39];RR=2.03，95%CI[1.37，2.99]），the group with TG+GC performed better than the group with GC（RR=1.46，95%CI[1.32，1.60]），and the group with CTX+GC performed better than the group with TG+GC（RR=0.35，95%CI[0.16，0.75]）. In terms of total effective rate, the group with TG performed better than the group with conventional therapy or GC（RR=1.44，95%CI[1.19,1.74];RR=1.30，95%CI[1.16，1.46]），the group with TG+GC performed better than the group with GC（RR=1.27，95%CI[1.21，1.34]），and the group with CTX+GC performed better than the group with TG+GC（RR=0.60，95%CI[0.43，0.85]）. No significant difference was found between the group with TG+GC and LEF+GC（RR=0.68，95%CI[0.30，1.53]）. In terms of urinary protein, urine occult blood negative time，the group with TG performed better than the group with conventional therapy（MD=-9.00，95% CI[-11.99，-6.01];MD=-12.00，95%CI[-16.13，-7.87]），the group with TG+GC performed better than the group with GC（MD=-8.86，95%CI[-10.08，-7.64];MD=-16.24，95%CI[-23.80，-8.67]）. In terms of recurrence rate, the group with TG+GC was lower than the group with GC（RR=0.13，95%CI[0.06，0.25]）, but there were no significant difference between the group with TG and conventional therapy（RR=0.43，95%CI[0.15，1.19]）. In adverse reactions, the common adverse effects of TG were gastrointestinal discomfort, liver damage and leucopenia. TG for the treatment of HSPN can improve clinical efficacy, reduce recurrence, and the adverse reactions are relatively safe. Due to the generally low methodological quality of the included studies, which affected the accuracy and reliability of the result. Therefore, more high-quality, large samples and multi-center randomized controlled trials are necessary for further evidence.
