PURPOSE:
Septic shock is associated with high mortality and poor outcomes among sepsis patients with coagulopathy. Although traditional statistical methods or machine learning (ML) algorithms have been proposed to predict septic shock, these potential approaches have never been systematically compared. The present work aimed to develop and compare models to predict septic shock among patients with sepsis.
METHODS:
It is a retrospective cohort study based on 484 patients with sepsis who were admitted to our intensive care units between May 2018 and November 2022. Patients from the 908th Hospital of Chinese PLA Logistical Support Force and Nanchang Hongdu Hospital of Traditional Chinese Medicine were respectively allocated to training (n=311) and validation (n=173) sets. All clinical and laboratory data of sepsis patients characterized by comprehensive coagulation indexes were collected. We developed 5 models based on ML algorithms and 1 model based on a traditional statistical method to predict septic shock in the training cohort. The performance of all models was assessed using the area under the receiver operating characteristic curve and calibration plots. Decision curve analysis was used to evaluate the net benefit of the models. The validation set was applied to verify the predictive accuracy of the models. This study also used Shapley additive explanations method to assess variable importance and explain the prediction made by a ML algorithm.
RESULTS:
Among all patients, 37.2% experienced septic shock. The characteristic curves of the 6 models ranged from 0.833 to 0.962 and 0.630 to 0.744 in the training and validation sets, respectively. The model with the best prediction performance was based on the support vector machine (SVM) algorithm, which was constructed by age, tissue plasminogen activator-inhibitor complex, prothrombin time, international normalized ratio, white blood cells, and platelet counts. The SVM model showed good calibration and discrimination and a greater net benefit in decision curve analysis.
CONCLUSION
The SVM algorithm may be superior to other ML and traditional statistical algorithms for predicting septic shock. Physicians can better understand the reliability of the predictive model by Shapley additive explanations value analysis.

OBJECTIVE:
To observe the effect of Guilu Taohong Formula on semen quality in varicocele (VC) models of rats, and to explore its possible mechanism.
METHODS:
Forty-eight male SD rats were randomly divided into four groups (sham group, model group, Guilu Taohong Formula group and L-carnitine group). After the establishment of models, the rats were treated with intragastric administration for eight consecutive weeks. The general condition of the rats was observed. After the gavage, the testicular and epididymal indices were calculated. Semen quality was assessed using an automatic semen analyzer. Apoptosis of testicular cells was assessed by TUNEL staining. And the expression levels of B-cell lymphocytoma-2 (Bcl-2), Bcl-2-associated X protein (Bax) and cysteine aspartate protease-3 (caspase-3) in testicular tissue were detected by Western blot.
RESULTS:
Compared with the sham group, testicular index, epididymal index, sperm concentration, the percentage of progressive motility of sperm (PR%) and the expression level of Bcl-2 decreased in model group(P<0.01). An increased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins were observed in model group as well(P<0.01). Compared with the model group, the testicular index, epididymal index, sperm concentration, PR% and the expression level of Bcl-2 in Guilu Taohong Formula group increased significantly (P<0.05, P<0.01). A decreased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins were detected in Guilu Taohong Formula group as well(P<0.01). Similarly, the L-carnitine group showed increased testicular index, epididymal index, sperm concentration, PR% and the expression level of Bcl-2 protein (P<0.05, P<0.01), where showed decreased apoptosis rate of spermatogenic cells and the expression levels of Bax and caspase-3 proteins compared with model group (P<0.01, P<0.05).
CONCLUSION
Guilu Taohong Formula improves semen quality in VC model rats and reduces the apoptosis rate of spermatogenic cells in testicular tissue, which may be related to the promotion of Bcl-2 protein expression and the inhibition of Bax and caspase-3 protein expression levels.

BACKGROUND:
Modern acupuncture anesthesia is a combination of Chinese and Western medicine that integrates the theories of acupuncture with anesthesia. However, some clinical studies of acupuncture anesthesia lack specific descriptions of randomization, allocation concealment, and blinding processes, with subsequent systematic reviews indicating a risk of bias.
OBJECTIVE:
Clinical trial registration is essential for the enhancement of the quality of clinical trials. This study aims to summarize the status of clinical trial registrations for acupuncture anesthesia listed on the World Health Organization International Clinical Trials Registry Platform (ICTRP).
SEARCH STRATEGY:
We searched the ICTRP for clinical trials related to acupuncture anesthesia registered between January 1, 2001 and May 31, 2023. Additionally, related publications were retrieved from PubMed, Cochrane Library, Embase, China National Knowledge Infrastructure, China Science and Technology Journal Database, and Wanfang Data. Registrations and publications were analyzed for consistency in trial design characteristics.
INCLUSION CRITERIA:
Clinical trials that utilized one of several acupuncture-related therapies in combination with pharmacological anesthesia during the perioperative period were eligible for this review.
DATA EXTRACTION AND ANALYSIS:
Data extracted from articles included type of surgical procedure, perioperative symptoms, study methodology, type of intervention, trial recruitment information, and publication information related to clinical enrollment.
RESULTS:
A total of 166 trials related to acupuncture anesthesia from 21 countries were included in the analysis. The commonly reported symptoms in the included studies were postoperative nausea and vomiting (19.9%) and postoperative pain (13.3%). The concordance between the publications and the trial protocols in the clinical registry records was poor, with only 31.7% of the studies being fully compatible. Inconsistency rates were high for sample size (39.0%, 16/41), blinding (36.6%, 15/41), and secondary outcome indicators (24.4%, 10/41).
CONCLUSION
The volume of acupuncture anesthesia clinical trials registered in international trial registries over the last 20 years is low, with insufficient disclosure of results. Postoperative nausea and vomiting as well as postoperative pain, are the most investigated for acupuncture intervention.

Objective:Compare the difference of Pharyngocutaneous fistula after total laryngectomy using thyroid gland flap and traditional strip muscle repair, find an effective way to reduce Pharyngocutaneous fistula after total laryngectomy. Methods:Sixty patients with locally advanced laryngeal malignancies were randomly divided into two groups with 30 cases in each group. After total laryngectomy, the experimental group was repaired with thyroid gland flap, and the control group was repaired with traditional strap muscle. Data of gender, age, intraoperative blood loss, operation time, neck lymph node dissection, combined diabetes mellitus, postoperative hypoproteinemia, tumor stage, repair mode and postoperative Pharyngocutaneous fistula were collected in the two groups. The incidence of Pharyngocutaneous fistula in the two groups was compared, and the independent risk factors of Pharyngocutaneous fistula after total laryngectomy were found by logistic regression analysis. Results:The incidence of Pharyngocutaneous fistula after total laryngectomy was 3.3%(1/30) in patients with thyroid gland flap repair and 26.7% (8/30) in patients with traditional strip muscle repair, with statistically significant difference(P<0.05). There was no significant correlation between gender, age, maximum tumor diameter, blood loss, operation time and Pharyngocutaneous fistula. Hypoproteinemia and repair mode were correlated with pharyngocutaneous fistula. Repair mode is an independent risk factor for Pharyngocutaneous fistula after total laryngectomy. Conclusion:The occurrence of Pharyngocutaneous fistula after total laryngectomy was decreased significantly by using pedicle thyroid flap compare to traditional surgery.The Pedicle thyroid flap can be considered as an effective clinical repairment to reduce postoperative Pharyngocutaneous fistula.

Abstract:Objective To improve the replication level of varicella⁃zoster virus(VZV)in human diploid cell line MRC⁃5
and increase the yield of VZV vaccine by reducing the expression of interferon(IFN)related genes via optimizing the cell
line MRC⁃5. Methods Interferon receptor 1(IFNAR1)silenced MRC⁃5 cell line(MRC⁃5IFNAR1⁃)was constructed by
CRISPR/Cas9 gene editing technology,which was determined for the relative expression of IFNAR1 mRNA,and for those
of mRNA of IFN related genes IFNβ and OAS1 after VZV infection by qRT⁃PCR to evaluate the effect of gene silencing.
Gene mutation sequences were further identified by sequencing of the silenced sites. The replication of VZV in MRC⁃5 and
MRC⁃5IFNAR1⁃ cell lines was compared 168 h after VZV infection by using qRT⁃PCR and plaque formation unit(PFU)assay,
to evaluate the effect of MRC⁃5IFNAR1⁃cell line on VZV replication. Results The growth status of MRC⁃5IFNAR1⁃ cell line wasconsistent with that of MRC ⁃ 5 cells,and the relative expression of IFNAR1 mRNA decreased by 73%;The relative
expressions of IFNβ and OAS1 mRNA in MRC⁃5IFNAR1⁃ cell line were 61% and 90% lower than those in MRC⁃ 5 cells
respectively after VZV infection;In addition,168 h after VZV infection,the level of DNA replication and the titer of VZV
increased by 5. 7 folds and 4 folds respectively. Conclusion The successful establishment of MRC⁃5IFNAR1⁃ cell line may be a
potential scheme to increase the yield of vaccines based on human diploid cells,and provided a reference for expanding
production of VZV vaccine.

ObjectiveTo assess the prognostic value of 18F-FDG PET/CT parameters for predicting therapeutic response in diffuse large B-cell lymphoma (DLBCL). MethodsWe retrospectively analyzed the clinical data and 18F-FDG PET/CT radiomics features of 81 DLBCL patients enrolled between June 2015 and October 2020. Multivariate logistic regression analysis was used to identify the predictive factors for therapeutic response of DLBCL, based on which a predictive model was developed accordingly. The performance of the model was evaluated by receiver operating characteristic (ROC) curves and calibration plots. ResultsDuring the two years after first chemotherapy, 23 patients (28.3%) developed relapse and 58 patients (71.7%) had progression-free survival (PFS). The analysis for the predictive capability of the binary logistic regression model incorporating the PET/CT features revealed that the imaging features of 18F-FDG PET/CT after chemotherapy were independent prognostic factors for PFS. Among them, SUVTHR-mean2 was the most important factor for predicting therapeutic response in DLBCL patients after chemotherapy, with a cutoff value of 2.00 (AUC=0.81). Conclusions18F-FDG PET/CT showed a valuable prognostic performance for PFS in DLBCL patients after chemotherapy, with the imaging feature after chemotherapy SUVTLR-mean2 being the optimal independent predictor. Our predictive model of imaging features might have an important prognostic value in assessing the risk of disease progression, guiding the treatment and follow-up protocol, improving therapeutic efficiency and cutting down the medical cost.
