ObjectiveTo investigate the role and mechanism of Go-Ichi-Ni-San complex subunit 1 (GINS1) in the progression of hepatocellular carcinoma (HCC) and the development of chemotherapy resistance. MethodsThe tumor database GEPIA2 was used to analyze the differential expression of GINS1 between HCC patients and healthy individuals, and pathological tissue samples were collected from 40 HCC patients who were admitted to The Affiliated Tumor Hospital of Xinjiang Medical University and the First Affiliated Hospital of Xinjiang Medical University from May 2017 to January 2021. Immunohistochemical staining was used to measure the difference in the expression of GINS1 between HCC tissue and corresponding adjacent tissue, and the correlation between the expression level of GINS1 and the clinical TNM stage of HCC was analyzed. Western blot was also used to measure the difference in the expression of GINS1 between HCC Huh7/Hep3B/Li-7/MHCC97H cell lines and normal human QSG7701 hepatocytes. The method of lentivirus transfection was used to establish the MHCC97H cell line with stable GINS1 knockdown and its negative control cell line. CCK-8 assay and colony formation assay were used to measure cell proliferative capacity; scratch assay was used to measure cell migration ability; Transwell assay was used to measure cell invasion ability; cells were treated with oxaliplatin to measure their sensitivity to chemotherapy drugs. Nude mice were used to establish a tumor-bearing model and observe the effect of GINS1 knockdown on the growth of HCC in vivo. Western Blot was used to measure the expression levels of the proteins associated with the Notch pathway and the JAK/STAT pathway. The cells were treated with the Notch receptor agonist Jagged-1 to analyze the association between GINS1 and the Notch/JAK/STAT pathway. The independent-samples t test was used for comparison of continuous data between two groups; a one-way analysis of variance was used for comparison between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsThe expression of GINS1 was upregulated in HCC patients, HCC tissue, and HCC cell lines (all P<0.05), and the expression level of GINS1 was positively correlated with the clinical TNM stage of HCC (r=0.822, P=0.011). Compared with the negative control cells, the GINS1-knockdown MHCC97H cells showed significant reductions in proliferation, migration, and invasion activities (all P<0.01) and a significantly enhanced sensitivity to oxaliplatin (P<0.01). Compared with the nude mice in the control group, GINS1 knockdown caused significant inhibition of tumor weight and volume in vivo in nude mice (all P<0.001). Compared with the negative control cells, the GINS1-knockdown MHCC97H cells showed significant reductions in the expression levels of Notch1, Notch3, p-JAK2, and p-STAT3 (all P<0.05), while there were no significant differences in the overall expression levels of JAK2 and STAT3 (P>0.05). After Jagged-1 treatment, the GINS1-knockdown MHCC97H cells showed significant increases in proliferation, migration, and invasion activities and a significant reduction in sensitivity to oxaliplatin, as well as significant increases in the levels of p-JAK2 and p-STAT3 (all P<0.05). ConclusionGINS1 is upregulated in HCC and can promote HCC progression and chemotherapy resistance through the Notch/JAK2/STAT3 pathway.

[Objective]To investigate primary and secondary transfer of exfoliated cells from human hands on non-porous substrates such as plastic steering wheel or computer mouse.[Methods]DNA detection sensitivity and detection limit for mixed DNA profiling were examined to understand our laboratory's ability to test for trace DNA.Forensic swabs were used to collect samples from volunteers'one-hour-long unwashed hands,substrates touched by volunteers'immediately or 30 min following shaking hands,and individual A's daily-use substrates touched by individual B and then by individual A again.Simulations were conducted to assess the potential for introduction of another person's exfoliated cells from hands into routine casework samples.[Results]Our laboratory can obtain a full DNA profile from as little as 0.020 ng of DNA and detect minor components in a 1:9 mixed DNA sample.85%of samples from unwashed hands yielded a full DNA profile.Primary transfer of a full DNA profile was found in 77%of substrates touched by volunteers'dominant hand 30 min after hand washing,allowing differentiation between good and poor shedders,with no significant difference in genders and substrate types.75%of substrates touched 30 min after hand washing and then immediately following handshaking yielded the other individual's DNA profile(secondary transfer),with the number of short tandem repeat(STR)loci detected ranging from 0 to 23;the percentage and number decreased substantially when the substrates were touched 30 minutes later.No foreign DNA was detected in routine casework samples with introduced exfoliated cells from hands.When two individuals took turns touching items with their hands,the major contributor to the DNA profile was not always the individual who made the last contact.[Conclusions]Primary and secondary DNA transfer can be detected on non-porous substrates,and based on the deposit of hand exfoliated cells,individuals can be categorized as good or poor shedders,which is an important factor affecting detection of DNA transfer.Besides considering the laboratory's DNA detection sensitivity,if DNA is detected on substrates by hand contact,we need to take into account the potential for secondary transfer at different levels of activity when interpreting the results.

Osteoporotic proximal humeral fracture (OPHF) is one of the common osteoporotic fractures in the aged, with an incidence only lower than vertebral compression fracture, hip fracture, and distal radius fracture. OPHF, secondary to osteoporosis and characterized by poor bone quality, comminuted fracture pattern, slow healing, and severely impaired shoulder joint function, poses a big challenge to the current clinical diagnosis and treatment. In the field of diagnosis, treatment, and rehabilitation of OPHF, traditional Chinese and Western medicine have accumulated rich experience and evidence from evidence-based medicine and achieved favorable outcomes. However, there is still a lack of guidance from a relevant consensus as to how to integrate the advantages of the two medical systems and achieve the integrated diagnosis and treatment. To promote the diagnosis and treatment of OPHF with integrated traditional Chinese and Western medicine, relevant experts from Orthopedic Expert Committee of Geriatric Branch of Chinese Association of Gerontology and Geriatrics, Youth Osteoporosis Group of Orthopedic Branch of Chinese Medical Association, Osteoporosis Group of Orthopedic Surgeon Branch of Chinese Medical Doctor Association, and Osteoporosis Committee of Shanghai Association of Integrated Traditional Chinese and Western Medicine have been organized to formulate Expert consensus on the diagnosis and treatment of osteoporotic proximal humeral fracture with integrated traditional Chinese and Western medicine ( version 2024) by searching related literatures and based on the evidences from evidence-based medicine. This consensus consists of 13 recommendations about the diagnosis, treatment and rehabilitation of OPHF with integrated traditional Chinese medicine and Western medicine, aimed at standardizing, systematizing, and personalizing the diagnosis and treatment of OPHF with integrated traditional Chinse and Western medicine to improve the patients ′ function.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Depression is a common mental illness in adolescents, and some patients do not respond well after medication, which may be partly related to vitamin D deficiency and insufficient calcium intake. This paper reports a 15-year-old patient with depression, whose condition was still unstable and the effect was not good despite routine use of antidepressant drugs and psychological intervention. After adequate supplementation of vitamin D and calcium, the patient's depression improved significantly, and the follow-up for 4 months, the condition was stable and did not recur.

Abstract: Objective To explore the distribution characteristics of protein gene product 9.5 (PGP9.5) in the proximal and distal lesions of liver tissue in patients with alveolar echinococcosis (AE), and to clarify the relationship between the positive nerve fiber density of PGP9.5 in the proximal lesion of liver tissue of patients with AE and clinical pathological features and biochemical indexes. Methods From July 2019 to July 2022, 59 patients with AE who were hospitalized in the Department of Hepatobiliary Surgery of the First Affiliated Hospital of Xinjiang Medical University were selected, and their liver tissues at the proximal and distal ends of the lesion were collected, and their clinicopathological data and biochemical index information were collected at the same time. Immunohistochemical method was used to detect the density of PGP9.5 positive nerve fibers in the proximal and distal liver tissues of 59 patients with AE, and to analyze the difference between the density of PGP9.5 positive nerve fibers in the proximal and distal liver tissues of patients with AE, and to further analyze the relationship between the density of PGP9.5 positive nerve fibers in the proximal liver tissues of patients with AE and clinicopathological features and biochemical indexes. Results The nerves in the proximal lesion of the liver tissue in patients with AE increased, mainly distributed in the outer layer of the fibrous capsule enclosing the lesion, and no obvious abnormalities were observed in the distal nerves. The density of PGP9.5 positive nerve fibers in the liver tissue of patients with AE was significantly higher than that in the distal part of the lesion, with statistical significance (Z=-4.237, P<0.05). The density of PGP9.5 positive nerve fibers in the liver tissue of patients with AE was correlated with the increase of liver volume (Z=-2.632, P<0.05). Conclusions The area of PGP9.5 positive nerve fibers in the proximal liver tissue of patients with alveolar echinococcosis increases, suggesting that PGP9.5 positive nerve is involved in the pathogenesis of AE, and its specific role needs further study.

Objective:To evaluate the application of a multi-task learning-based light-weight convolution neural network (MTLW-CNN) for the automatic segmentation of organs at risk (OARs) in thorax.Methods:MTLW-CNN consisted of several layers for sharing features and 3 branches for segmenting 3 OARs. 497 cases with thoracic tumors were collected. Among them, the computed tomography (CT) images encompassing lung, heart and spinal cord were included in this study. The corresponding contours delineated by experienced radiation oncologists were ground truth. All cases were randomly categorized into the training and validation set ( n=300) and test set ( n=197). By applying MTLW-CNN on the test set, the Dice similarity coefficients (DSCs) of 3 OARs, training and testing time and space complexity (S) were calculated and compared with those of Unet and DeepLabv3+ . To evaluate the effect of multi-task learning on the generalization performance of the model, 3 single-task light-weight CNNs (STLW-CNNs) were built. Their structures were totally the same as the corresponding branches in MTLW-CNN. After using the same data and algorithm to train STLW-CNN, the DSCs were statistically compared with MTLW-CNN on the testing set. Results:For MTLW-CNN, the averages (μ) of lung, heart and spinal cord DSCs were 0.954, 0.921 and 0.904, respectively. The differences of μ between MTLW-CNN and other two models (Unet and DeepLabv3+ ) were less than 0.020. The training and testing time of MTLW-CNN were 1/3 to 1/30 of that of Unet and DeepLabv3+ . S of MTLW-CNN was 1/42 of that of Unet and 1/1 220 of that of DeepLabv3+ . The differences of μ and standard deviation (σ) of lung and heart between MTLW-CNN and STLW-CNN were approximately 0.005 and 0.002. The difference of μ of spinal cord was 0.001, but σof STLW-CNN was 0.014 higher than that of MTLW-CNN.Conclusions:MTLW-CNN spends less time and space on high-precision automatic segmentation of thoracic OARs. It can improve the application efficiency and generalization performance of the models.

Objective:To explore a three-dimensional dose distribution prediction method for the left breast cancer radiotherapy planning based on full convolution network (FCN), and to evaluate the accuracy of the prediction model.Methods:FCN was utilized to achieve three-dimensional dose distribution prediction. First, a volumetric modulated arc therapy (VMAT) plan dataset with 60 cases of left breast cancer was built. Ten cases were randomly chosen from the dataset as the test set, and the remaining 50 cases were used as the training set. Then, a U-Net model was built with the organ structure matrix as inputs and dose distribution matrix as outputs. Finally, the model was adopted to predict the dose distribution of the cases in the test set, and the predicted 3D doses were compared with actual planned results.Results:The mean absolute differences of PTV, ipsilateral lung, heart, whole lung and spinal cord for 10 cases were (119.95±9.04) cGy, (214.02±9.04) cGy, (116.23±30.96) cGy, (127.67±69.19) cGy, and (37.28±18.66) cGy, respectively. The Dice similarity coefficient (DSC) of the prediction dose and the planned dose in the 80% and 100% prescription dose range were 0.92±0.01 and 0.92±0.01. The γ rate of 3 mm/3% in the area of 80% and 10% prescription dose range were 0.85±0.03 and 0.84±0.02. Conclusion:FCN can be used to predict the three-dimensional dose distribution of left breast cancer patients undergoing VMAT.
