Objective:To explore the clinical application value of 18F-FDG PET/CT radiomics in predicting B-cell lymphoma-2 (BCL-2)/immunoglobulin heavy chain (IgH) fusion gene expression status in follicular lymphoma (FL) patients. Methods:A retrospective analysis was conducted on the clinical and imaging data of 90 FL patients (46 males and 44 females, age (48.7±10.5) years) who underwent 18F-FDG PET/CT examinations at Henan Cancer Hospital from January 2016 to August 2023. According to the expression status, patients were divided into positive group and negative group. Patients were randomly divided into training set ( n=62) and validation set ( n=28) at a ratio of 7∶3. PET and CT radiomics features were extracted by LIFEx 7.3.11 software. After using least absolute shrinkage and selection operator (LASSO) regression and ten-fold cross-validation for feature selection, PET and CT radiomics models were constructed. Univariate and multivariate analyses were used to select important clinical features and construct clinical model. Finally, a combined model was established by combining the radiomics features with clinical features. ROC curve and AUC were used to evaluate the predictive performance of models, and Delong test was used to compare the differences in AUCs. Results:After features selection, a total of 3 PET radiomics features, 3 CT radiomics features and 2 clinical features were selected for the construction of radiomics model and clinical model respectively. Multivariate analysis of clinical data showed that pathological grade (odds ratio ( OR)=0.201, 95% CI: 0.052-0.699, P=0.014) and maximum diameter of the maximum lesion (D max) ( OR=1.033, 95% CI: 1.009-1.065, P=0.017) were associated with BCL-2/IgH expression status. In the training set, the AUCs of clinical model, PET radiomics model, CT radiomics model and combined model were 0.84, 0.80, 0.80 and 0.91 respectively. In the validation set, the AUCs of the four models were 0.55, 0.61, 0.66 and 0.71 respectively. The combined model exhibited a trend toward higher in AUC than other three models in both the training and validation sets ( z values: 0.50-1.71, P values: 0.087-0.620). Conclusion:It is valuable to predict BCL-2/IgH fusion gene expression status based on PET/CT radiomics combined with clinical features.

Objective:To explore the expressions of serum N-terminal osteocalcin (N-MID) and cytokeratin (CK) 5/6 in primary lung cancer patients with bone metastasis and their clinical significances.Methods:The clinical data of 96 patients with primary lung cancer admitted to Chengdu Second People's Hospital between February 2019 to February 2022 were retrospectively analyzed. All patients were divided into the bone metastasis group (38 cases) and the non-bone metastasis group (58 cases) according to whether bone metastasis occurred, and 45 healthy people who underwent physical examination during the same period were treated as the healthy control group. The expression levels of serum N-MID and CK5/6 in the bone metastasis group, the non-bone metastasis group and the healthy control group were compared. Logistic regression was used to analyze the factors affecting bone metastasis in patients with primary lung cancer; receiver operating characteristic (ROC) curve analysis was used to analyze the value of the expression levels of serum N-MID and CK5/6 in predicting bone metastasis in patients with primary lung cancer.Results:The composition ratio of patients with pathological stage Ⅲ-Ⅳ, serum bone-derived alkaline phosphatase and N-MID expression levels in the bone metastasis group were higher than those in the non-bone metastasis group (all P < 0.05). The expression level of serum N-MID in the bone metastasis group and non-bone metastasis group was higher than that in the healthy control group [(26.0±5.3) ng/ml, (15.3±3.1) ng/ml vs. (9.9±1.7) ng/ml, F = 224.27, P < 0.001], and there were statistically significant differences in the serum N-MID expression level of the pairwise comparison among the three groups (all P < 0.05). The expression level of serum CK5/6 in the bone metastasis group and the non-bone metastasis group was lower than that in the healthy control group [(3.6±0.7) ng/ml, (7.3±1.4) ng/ml vs. (10.6±2.4) ng/ml, F = 178.11, P < 0.001], and there were statistically significant differences in the serum CK5/6 expression level of the pairwise comparison among the three groups (all P < 0.05). Multivariate analysis showed that CK5/6, N-MID and bone-derived alkaline phosphatase were independent affecting factors for bone metastasis in patients with primary lung cancer ( OR = 4.088, 3.615, 2.892, all P < 0.05). ROC curve analysis showed that the optimal cut-off values of serum N-MID and CK5/6 expression levels for predicting bone metastasis in patients with primary lung cancer were 18.59 ng/ml and 4.71 ng/ml; the corresponding the area under the curve (AUC) was 0.881 and 0.862, respectively; and the specificity and AUC of the combination of serum N-MID and CK5/6 in predicting the bone metastasis in patients with primary lung cancer was 98.28% and 0.937 (95% CI 0.869-0.977), respectively; the AUC predicted by the combination of both was higher than that by serum N-MID or CK5/6 single (all P < 0.001). Conclusions:The expression levels of serum N-MID and CK5/6 in primary lung cancer patients with bone metastasis are abnormally changed. Clinical detection of serum N-MID and CK5/6 expression levels may be used as sensitive indicators for predicting the bone metastasis in patients with primary lung cancer.

Objective This study proposes to visually review the current situation and progress of standards sets by the International Organization for Standardization/Technical Committee on Traditional Chinese Medicine (ISO/TC 249). The review aims to explore the development strategies of the standards, which will exhibit the considerable impact on the economy, trade and exchanges, and cooperation in the area of traditional Chinese medicine (TCM). Methods ISO/TC 249 standards were searched on the ISO website, and their title, proposed time, current stage, scope, and classification were obtained for further summarization. Gephi was utilized to portray the co-occurrence network graph of the ISO/TC 249 standards subject. Results In ISO/TC 249, there were 116 standards, including 81 published standards and 35 developing standards by April 30, 2022. Two withdrawal standards were published after revision, which were not counted in the total standards. The number of published standards has been increasing since the first standard was published in 2014, whose title was “Sterile acupuncture needles for single use”. Among these standards, 17.24% (20/116) standards were in review, 56.03% (65/116) in publication, 3.45% (4/116) in approval, 5.17% (6/116) in enquiry, 3.45% (4/116) in committee, and 14.66% (17/116) in preparation, respectively. With 116 standards, most of the research focused on the medicament, as its classification of the International Classification for Standards (ICS) showed the proportion reaching 49.54%. The network analysis data revealed that the top five most frequent words were “materials” “root” “requirements” “products” and “system”, after removing the noise data, such as prepositions, conjunctions, and pronouns. Additionally, the word “system” co-exists with the terms “computerized” “coding” “image” “tongue” and “analysis”; the word “requirement” co-exists with “manufacturing” “decoction” “process” and “materials”; whereas the word “devices” co-exists with “pulse” “electric” “skin” and “measurement”. Conclusion With the increased diversification and complexity of problems, the development of standards is also oriented to multidisciplinary fields to cultivate the interdisciplinary talents, and especially the international standardization talents of compound TCM. Multi-angle analysis, formulation, and demonstration of standards, in line with industry needs in different disciplines, enhance the availability of standards and the ability to serve the industry.

Objective:To investigate the effect of pelvic packing on the control of intractable postpartum hemorrhage after emergency perinatal hysterectomy (EPH).Methods:Eleven cases with complete clinical data of pelvic packing due to failure of hemostasis after EPH were collected to evaluate the outcome, complications, hospital stay of pregnant women, and to analyze the factors affecting the effect of pelvic packing. The cases included patients who were admitted to the Third Affiliated Hospital of Guangzhou Medical University after pelvic packing treatment in the other hospital due to continuous bleeding after EPH or who were referred to our hospital for pelvic packing treatment due to continuous bleeding after EPH from January 2014 to August 2021.Results:The median gestational week of 11 pregnant women was 38.3 weeks(38.0-39.9 weeks) , and the methods of termination of pregnancy were cesarean section in 7 cases (7/11) and vaginal delivery in 4 cases (4/11). The median time between postpartum hemorrhage and pelvic tamponade was 10 hours (5-57 hours), the median amount of bleeding was 8 500 ml(4 800-15 600 ml) , the median number of pelvic tamponade was 3 pieces (2-7 pieces), and the median retention time of gauze pad was 6.0 days (3.0-6.0 days). The median frequency of laparotomy in this pregnancy was 3 times (2-3 times), with a maximum of 4 among the 11 cases, the first pelvic packing was successful in hemostasis in 9 cases, and the final successful treatment in all of the 11 cases. All parturients had hemorrhagic shock (11/11) and disseminated intravascular coagulation (11/11) before pelvic packing. Other common complications were multiple organ dysfunction syndrome (9/11), cardiac arrest (4/11), deep vein thrombosis (3/11), septic shock (3/11), and intestinal obstruction (1/11). All parturients took out the gauze after the coagulation function returned to normal and there was no active bleeding. The recovery time of coagulation function in 11 cases was 3 days (3-5 days), the retention time of gauze pad was 6 days (3-6 days), the median length of stay in intensive care unit was 14 days (11-26 days), and the median total length of stay was 22 days (16-49 days).Conclusions:Pelvic packing could be used as a temporary strategy for intractable postpartum hemorrhage after EPH, which provides a key time for injury control resuscitation for patients with unstable vital signs. This technology provides an opportunity for referral to superior medical institutions and further treatment.

Objective:To summarize the clinical features of special portal hypertension-Abernethy malformation reported at home and abroad.Methods:The relevant literature on Abernethy malformation published at home and abroad from January 1989 to August 2021 was collected. Patients'clinical features, imaging and laboratory test results, diagnosis, treatment, and prognosis were analyzed.Results:A total of 380 cases were included from 60 and 202 domestic and foreign literatures. Among them, there were 200 cases of type I, with 86 males and 114 females, and the average age was (17.08±19.42) years, while there were 180 cases of type II, with 106 males and 74 females, and the average was (14.85±19.60) years. The most common reason for the first visit of an Abernethy malformation patient's was gastrointestinal system symptoms such as hematemesis and hematochezia caused by portal hypertension (70.56%). Multiple malformations were present in 45.00% of type Ⅰ and 37.80% of type Ⅱ patients. The most prevalent condition was congenital heart disease (62.22%, and 73.53%). Complications related to Abernethy malformation was occurred in 127 and 105 cases with type I and type II, respectively, with liver lesions in 74.02% (94/127) and 39.05% (42/105) and hepatopulmonary syndrome of 33.07% (42/127) and 39.05% (41/105), respectively. The imaging diagnosis of type I and type II Abernethy malformations were mainly based on abdominal computed tomography (59.00%, and 76.11%). Liver pathology was performed in 27.10% of patients. Blood ammonia increased by 89.06% and 87.50%, and AFP increased by 29.63% and 40.00% in laboratory findings. 9.76% (8/82) and 6.92% (9/130) died, while 84.15% (61/82) and 88.46% (115/130) had improved conditions after medical conservative, or surgical treatment.Conclusion:Abernethy malformation is a rare disease in which congenital portal vein development abnormalities lead to significant portal hypertension and portasystemtic shunt. Patients often seek medical treatment for gastrointestinal bleeding and abdominal pain. Type Ⅰ is more common in women, often associated with multiple malformations, and prone to secondary intrahepatic tumors. Liver transplantation is the main treatment method. Type Ⅱ is more prevalent in males, and shunt vessel occlusion is the first treatment choice. Overall, type Ⅱ has a better therapeutic impact than type Ⅰ.
