ObjectiveTo investigate the immunological characteristics of the patients with aplastic anemia （AA） and elevated hemogram parameters treated with Yiqi Yangxue prescription combined with Western medicine and the predictive effects of immunological indexes on elevated hemogram parameters， thus providing a reference for the prediction of the treatment efficacy and the adjustment of the treatment regimen. MethodA retrospective study was conducted， involving 77 AA patients treated with Yiqi Yangxue prescription combined with Western medicine for 6 months in 19 medical institutions including Xiyuan Hospital， China Academy of Chinese Medical Sciences from September 2018 to March 2021. The patients were assigned into two groups according to the elevations in hemogram parameters ［including hemoglobin （HGB）， white blood cell count （WBC）， platelet （PLT）， and absolute neutrophil count （ANC）］ after 6 months of treatment. One group had the elevation <50%， and the other group had the elevation ≥50% compared with the baseline. The clinical and immunological characteristics were compared between the two groups. Result① Compared with the group with HGB elevation<50%， the group with HGB elevation≥50% showed elevated level of CD3⁺ human leukocyte antigen-DR （HLA-DR）⁺ and increased proportion of patients with T-helper cell type 2 （Th2）<5%， CD8⁺≥50%， and CD3⁺HLA-DR⁺≥9% before treatment （P<0.05， P<0.01）. The multivariate Logistic regression analysis showed that CD8⁺≥50% before treatment was the independent influencing factor for HGB elevation ≥50% ［odds ratio （OR）=12.000， 95% confidence interval （CI） 2.218， 64.928， P<0.01］. ② Compared with the group with WBC elevation<50%， the group with WBC elevation≥50% showed increased proportion of patients with CD3⁺HLA-DR⁺<6% and T-box transcription factor （T-bet）≥200% before treatment （P<0.05）. The multivariate Logistic regression analysis showed that CD3⁺HLA-DR⁺<6% （OR=2.998， 95%CI 1.036， 8.680， P<0.05） and T-bet≥200% （OR=3.634， 95%CI 1.076， 12.273， P<0.05） before treatment were independent influencing factors for WBC elevation≥50%. ③ Compared with the group with PLT elevation<50%， the group with PLT elevation≥50% presented lowered Th1 and CD3⁺HLA-DR⁺ levels and increased proportion of patients with Th1<12%， CD4⁺≥6%， and CD3⁺HLA-DR⁺<5% before treatment （P<0.05， P<0.01）. The multivariate Logistic regression analysis showed that CD3⁺HLA-DR⁺<5% before treatment was the independent influencing factor for PLT elevation≥50% （OR=16.190， 95%CI of 3.430 to 76.434， P<0.01）. ④ Compared with the group with ANC elevation<50%， the group with ANC elevation≥50% showed no significant changes in the hemogram parameters before treatment. ConclusionAs for the AA patients with rapid elevation in HGB， Yiqi Yangxue prescription combined with Western medicine demonstrate significant effects in the patients with Th2<5% and CD3⁺HLA-DR⁺≥9%， especially those with CD8⁺≥50%. As for the AA patients with rapid elevation in WBC， the therapy was particularly effective in the patients with CD3⁺HLA-DR⁺<6% and T-bet≥200%. As for the AA patients with rapid growth in PLT， the therapy was particularly effective in the patients with Th1<12% and CD4⁺≥6%， especially those with CD3⁺HLA-DR⁺<5%.

Objective: To investigate the situation of road traffic injuries (RTIs) among middle school students in Shaoxing City, Zhejiang Province, so as to provide the basis for implementation of interventions against RTIs among students. Methods: From 2021 to 2023, a multi-stage stratified cluster sampling method was used to select 82 junior high school classes and 89 senior high school classes in Shaoxing City as the survey population. Data on basic information, commuting travel, road safety behaviors and road safety knowledge awareness were collected through questionnaires, and the prevalence of RTIs in the past year was analyzed. Results: A total of 6 287 middle school students were surveyed, and 971 cases of RTIs were reported, with a reporting rate of 15.44%. The reporting rate of RTIs was higher in males than in females (17.68% vs. 13.34%, P<0.05). The reporting rate of RTIs was higher in high school students than in junior high school students (17.70% vs. 12.66%, P<0.05). The students who mainly walked to school (18.00%), walked 5 days a week (17.82%) and traveled with classmates (17.58%) had higher reporting rates of RTIs. Among those who walked for ≥20 minutes, the reporting rate of RTIs was higher in males than in females (P<0.05). Among different road safety behaviors, the reporting rate of RTIs was higher in males than in females who used electronic devices (P<0.05). The reporting rates of RTIs were relatively high among students who played for ≥10 minutes on the way (32.92%), crossed traffic lights directly when being late for school (41.54%) and crossed traffic barriers directly (30.67%). The reporting rate of RTIs among middle school students decreased with the increase of road safety knowledge scores (P<0.05). Conclusions Male students, high school students, students with road risky behaviors and with low awareness of road safety knowledge have higher reporting rates of RTIs. It is necessary to strengthen road safety knowledge education for students.

The incidence and detection rates of benign and low-grade malignant pancreatic tumors have risen yearly.For patients with such tumors,traditional radical resection procedures often result in excessive loss of normal pancreatic parenchyma,leading to complications such as postoperative insufficiency of both exocrine and endocrine functions.Studies have shown that functional-preserving surgeries,such as minimally invasive enucleation or partial resection surgeries,can maximize the protection of patients'pancreatic function and improve long-term quality of life.However,for some tumors deep within the pancreatic parenchyma,accurately locating the tumor and protecting the pancreatic duct pose challenges.Intraoperative ultrasound(IOUS)has become an ideal intraoperative imaging tool,often referred to as the surgeon's"third eye"because of its portability,ability to provide real-time high-resolution information,non-reliance on ionizing radiation,and the fact that it does not require special patient preparation.With advancements in technology,the application scope of IOUS has expanded beyond its initially limited diagnostic role to various surgical applications,including identifying non-palpable lesions,guiding surgical strategies,and staging tumors.In the current era of minimally invasive and precision surgery,the proficiency of surgeons in using IOUS has become an important issue.This article reviews the history of IOUS applications,summarizes the advantages and basic usage methods of robotic IOUS,and shares techniques for applying IOUS in robot-assisted precise resection of pancreatic tumors.

BACKGROUND: LY01005 (Goserelin acetate sustained-release microsphere injection) is a modified gonadotropin-releasing hormone (GnRH) agonist injected monthly. This phase III trial study aimed to evaluated the efficacy and safety of LY01005 in Chinese patients with prostate cancer. METHODS: We conducted a randomized controlled, open-label, non-inferiority trial across 49 sites in China. This study included 290 patients with prostate cancer who received either LY01005 or goserelin implants every 28 days for three injections. The primary efficacy endpoints were the percentage of patients with testosterone suppression ≤50 ng/dL at day 29 and the cumulative probability of testosterone ≤50 ng/dL from day 29 to 85. Non-inferiority was prespecified at a margin of -10%. Secondary endpoints included significant castration (≤20 ng/dL), testosterone surge within 72 h following repeated dosing, and changes in luteinizing hormone, follicle-stimulating hormone, and prostate specific antigen levels. RESULTS: On day 29, in the LY01005 and goserelin implant groups, testosterone concentrations fell below medical-castration levels in 99.3% (142/143) and 100% (140/140) of patients, respectively, with a difference of -0.7% (95% confidence interval [CI], -3.9% to 2.0%) between the two groups. The cumulative probabilities of maintaining castration from days 29 to 85 were 99.3% and 97.8%, respectively, with a between-group difference of 1.5% (95% CI, -1.3% to 4.4%). Both results met the criterion for non-inferiority. Secondary endpoints were similar between groups. Both treatments were well-tolerated. LY01005 was associated with fewer injection-site reactions than the goserelin implant (0% vs . 1.4% [2/145]). CONCLUSION: LY01005 is as effective as goserelin implants in reducing testosterone to castration levels, with a similar safety profile. TRIAL REGISTRATION ClinicalTrials.gov, NCT04563936.

ObjectiveTo explore the predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating aplastic anemia （AA） in non-elderly adults， so as to provide a reference for predicting the prognosis of this therapy. MethodA retrospective study was conducted with the clinical data of non-elderly adult AA patients who visited 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 and were treated with Yiqi Yangxue Prescription combined with western medicine. According to the efficacy evaluation results at the 6^th month of treatment， the patients were assigned into effective and ineffective groups. The two groups were compared in terms of the gender， age， disease classification ［non-severe aplastic anemia （NSAA）/severe aplastic anemia （SAA）］， course of disease， family history， complications， history of drug allergy， baseline blood routine examination ［hemoglobin （HGB）， white blood cell （WBC）， neutrophil （ANC）， platelet （PLT）， and reticulocyte （Ret）］， T lymphocyte subsets， degree of proliferation of nucleated cells in bone marrow， and expression of T-bet and GATA-3. ResultA total of 101 non-elderly adult AA patients were enrolled in this study， including 81 in the effective group and 20 in the ineffective group. The effective group had a higher proportion of the patients without a history of drug allergy than the ineffective group （P<0.05）. The body height， body weight， gender， age， disease classification， course of disease， family history， and complications showed no significant differences between two groups. The effective group had higher levels of ANC and PLT before treatment （P<0.05） and higher proportion of patients with ANC≥1.6×10⁹/L and PLT≥25×10⁹/L （P<0.05， P<0.01） than the ineffective group. The baseline levels of WBC， HGB， and Ret showed no significant statistical differences between two groups. The levels of CD3⁺HLA-DR⁺T cells in the effective group before treatment was higher than that in the ineffective group （P<0.05）. The levels of CD3⁺CD19^-T cells， CD4⁺T cells， CD8⁺T cells， Th1 cells， Th2 cells， and CD3⁺CD25⁺T cells showed no significant statistical differences between two groups before treatment. The proportion of patients with active bone marrow nucleated cells proliferation in the effective group before treatment were significantly higher than that in the ineffective group, while the proportion of patients with reduced or extremely reduced proliferation were significantly lower than that in the ineffective group （P<0.05）. The expression levels of T-bet and GATA-3 genes had no significant differences between two groups before treatment. The multivariate binary logistic regression analysis showed that the ANC level before treatment and history of drug allergy were independent influencing factors for efficacy （P<0.05， P<0.01）， while other indicators were not influencing factors for efficacy. The receiver operating characteristic （ROC） curve was applied to analyze the predictive value of the ANC level before treatment in the treatment of AA in non-elderly adults with Yiqi Yangxue prescription combined with western medicine. The area under the curve was 0.679 （P<0.05）， with the critical value of 1.595×10⁹/L， the sensitivity of 0.42， and the specificity of 0.95. ConclusionThe history of drug allergy， pre-treatment ANC， PLT， CD3⁺HLA-DR⁺ T cell levels， and proliferation of nucleated cells in bone marrow before treatment are predictive factors for the efficacy of Yiqi Yangxue prescription combined with western medicine in treating AA in non-elderly adults. This therapy tends to be more effective for the patients with no history of drug allergy， higher ANC and PLT levels before treatment， especially those with ANC≥1.6×10⁹/L， PLT≥25×10⁹/L， and higher CD3⁺ HLA-DR⁺T cell levels and the more active proliferation of nucleated cells in bone marrow before treatment.

ObjectiveTo investigate the predictive indicators of early efficacy of Bushen Shengxue prescription combined with western medicine in the treatment of aplastic anemia， and provide prognosis indicators for the treatment of aplastic anemia （AA） with kidney-tonifying therapy in traditional Chinese medicine （TCM） combined with western medicine. MethodA total of 126 patients treated by Bushen Shengxue prescription combined with western medicine in 19 hospitals including Xiyuan Hospital of the China Academy of Chinese Medical Sciences from September 2018 to March 2021 were selected for a retrospective study. The therapy was proven to be effective after six months of treatment. According to the efficacy after 4 months of treatment， the patients were assigned into a 4-month effective group and a 4-month ineffective group. The age， sex， disease severity （including severe aplastic anemia and non-severe aplastic anemia）， course of disease， degree of bone marrow nucleated cell proliferation， baseline hemogram levels ［including white blood cell count （WBC）， absolute neutrophil count （ANC）， hemoglobin （HGB）， platelets （PLT）， and reticulocytes （RET）］， T lymphocytes subsets， and the expression levels of T-box transcription factor （T-bet） and GATA-binding protein-3 （GATA-3） were compared between the two groups before treatment. ResultThe proportions of patients within the age ranges of ［20， 40） and ［60， 80） were higher in the 4-month effective group （P<0.05）. The sex， disease severity， course of disease， and comorbidities had no significant differences between the two groups. The 4-month effective group had higher baseline levels of HGB， WBC， ANC， and PLT than the 4-month ineffective group （P<0.05）， and there was no significant difference in the RET level between the two groups before treatment. Binary Logistic regression analysis showed that the PLT level before treatment was an independent factor affecting the onset time， while other indicators did not affect the onset time. The receiver operating characteristic （ROC） curve was established to analyze the value of PLT level before treatment for predicting the onset time， and the area under the curve was 0.691. With the critical value of 40.5×10⁹/L， the sensitivity and specificity of the prediction that the therapy will take effect within 4 months were 0.569 and 0.893， respectively. The two groups of patients were graded according to age ｛（14， 20）， ［20， 40）， ［40， 60）， and ［60， 80）｝ and PLT level before treatment （PLT<40×10⁹/L， PLT≥40×10⁹/L）. The proportion of the patients with PLT≥40×10⁹/L before treatment in the 4-month effective group was significantly higher than that in the 4-month ineffective group （P<0.05）. The degree of bone marrow nucleated cell proliferation before treatment had no significant difference between the two groups. The level of total T lymphocytes in the 4-month effective patients was lower than that in the 4-month ineffective patients before treatment （P<0.05）. The levels of Th1 cells， Th2 cells， CD4⁺ T cells， and CD8⁺ T cells showed no significant differences between the two groups before treatment. The T-bet expression level in the 4-month effective group was higher than that in the 4-month ineffective group before treatment （P<0.05）， while the expression level of GATA-3 showed no significant difference between the two groups before treatment. ConclusionBushen Shengxue prescription combined with western medicine will achieve faster effect for the patients within the age ranges of ［20， 40） or ［40， 60）， with higher levels of HGB， WBC， ANC， and PLT （especially those with PLT≥40×10⁹/L）， lower level of total T lymphocytes， or higher T-bet expression level before treatment.

Objective:To evaluate the value of 18F-FDG PET/CT in the diagnosis and treatment of primary breast lymphoma (PBL). Methods:Clinical data and 18F-FDG PET/CT imaging data of 6 patients (all females, age 46-79 years) with pathologically diagnosed primary breast diffuse large B cell lymphoma (PB-DLBCL) in Xishan People′s Hospital of Wuxi City and Affiliated Hospital of Jiangnan University from July 2015 to October 2021 were analyzed retrospectively. A total of 10 18F-FDG PET/CT scans were done for primary staging (6 scans of 6 patients), evaluation of treatment response (3 scans of 2 patients), and recurrence detection (1 scan of 1 patient). 18F-FDG PET/CT image analysis was performed qualitatively (visually) and semi-quantitatively (SUV max). Treatment response was evaluated by Deauville scores. Results:All 6 patients were diagnosed pathologically as PB-DLBCL (3 patients by core needle biopsy, 3 patients by biopsy after lumpectomy). All 6 patients were staged using baseline 18F-FDG PET/CT before chemotherapy. For 3 patients diagnosed by core needle biopsy, baseline 18F-FDG PET/CT showed unilateral breast lesion with high FDG uptake (SUV max: 23.0, 52.9, and 33.6). For 3 postoperative patients, baseline 18F-FDG PET/CT showed flocculent soft tissue density in the operative area with low FDG uptake (SUV max: 3.4, 2.2 and 2.0). Patient No.2 showed a large left breast mass with left axillary lymph node involvement by baseline PET/CT, and multiple nodular uptakes in bilateral breast (Deauville score of 4) after 4 courses of chemotherapy and negative result (Deauville score of 1) after 3 courses of new chemotherapy regimens by PET/CT. Patient No.4 showed right breast lesion and right axillary lymph nodes by routine preoperative imaging examination, but left breast lesion by postoperative PET/CT. According to the results of 18F-FDG PET/CT, patient No.4 was with complete response (Deauville score of 1) after treatment, but recurrence (Deauville score of 5) occurred after 7 months follow-up. Conclusion:18F-FDG PET/CT can play an important role in every step of management (diagnosis and staging, treatment response evaluation and detection of recurrence) in patients with PB-DLBCL.

Objective:To explore the application and preliminary evaluation of multidisciplinary rounds (MDRs) in the clinical teaching of urology.Methods:A total of 20 pediatrics medical students in the clinical medicine were selected as the control group, and the traditional single department teaching rounds were used. Another 20 clinical medical students in the same grade were taken as the experimental group, and MDRs were used. The teaching officer of urology served as the general ward round teacher, combined with nephrology physicians and imaging ultrasound physicians to conduct bedside teaching rounds, and the length of the rounds was about 60 to 90 minutes. Through the teaching evaluation form and the test scores, the effect of teaching ward rounds was evaluated. SPSS 21.0 was used for statistical evaluation data, and the unpaired t-test was performed to make comparison between groups. Results:In terms of theoretical test, the average score of students in the experimental group was (92.15±0.60), which was higher than that in the control group (90.05±0.71), and the difference was statistically significant ( P=0.030). In the experimental group, 95.0%(19/20) of the medical students affirmed the MDRs model, and 100% of them thought it was necessary to introduce this model in clinical teaching. Conclusion:MDRs are patient-centered, emphasize interdisciplinary cooperation, and are operable, which deepens the understanding of medical students on urological diseases, promotes the exchange of clinical teaching experience between urology and interdisciplinary research, and improves the quality of teaching.

Objective:To study the correlation between type 2 innate lymphocyte (ILC2) and Treg/Th17 ratio in the peripheral blood of patients at different stages of Mycobacterium tuberculosis ( Mtb) infection. Methods:This study recruited 30 individuals with active tuberculosis (ATB group), 26 with treated tuberculosis (RTB group), 22 with latent tuberculosis infection (LTBI group) and 17 negative for tuberculin skin test (TST-negative group). Flow cytometry was used to detect the proportion of ILC2 in CD45 + cells, and that of Th17 and Treg cells in CD4 + T lymphocytes in the peripheral blood of patients in each group. Expression of Foxp3 and RORγt at mRNA level was detected by real-time fluorescence quantitative PCR. Pearson method was used to analyze the correlation between Th17 and Treg, and that between ILC2 and Treg/Th17 ratio in the peripheral blood of patients with ATB and RTB. Results:The proportions of ILC2 in RTB and ATB groups were significantly higher than those of LTBI and TST-negative groups, and the proportion of ILC2 in RTB group was significantly higher than that of ATB group ( P<0.05). The proportion of Th17 in RTB group was lower than that of ATB group ( P<0.05), and the proportions of Th17 in ATB and RTB groups were lower than those of LTBI and TST-negative groups. The proportion of Treg in RTB group was lower than that of ATB group ( P<0.05), and close to that of LTBI group and TST-negative group, but the Treg/Th17 ratios in ATB and RTB groups were higher than those of LTBI and TST-negative groups. There was no significant difference in Treg/Th17 ratio between ATB and RTB groups ( P>0.05). The expression of Foxp3 and RORγt at mRNA level and Foxp3/RORγt ratio changed accordingly. Meanwhile, there was no correlation between Th17 and Treg in ATB or RTB group ( r=0.023, P=0.444; r=0.428, P=0.150). There was a positive correlation between ILC2 and Treg/Th17 ratio in ATB group ( r=0.794, P=0.000), while no correlation was found between ILC2 and Treg/Th17 ratio in RTB group ( r=0.197, P=0.297). Conclusions:In this study, the proportion of ILC2 was increased in the peripheral blood of TB patients, and the proportion of ILC2 in RTB group was higher than that of ATB group. In RTB group, Th17 accounted for a low proportion in the peripheral blood and was involved in inflammatory reactions, while Tregs were not involved in inflammatory reactions, but might have a certain inhibitory effect in patients with ATB. Further studies found that Th17-involved inflammatory reactions were not regulated by Tregs. ILC2 was involved in Treg/Th17 imbalance in ATB patients, but not in RTB patients.

ObjectiveTo investigate the efficacy of Bushen Shengxue prescription and Yiqi Yangxue prescription in the treatment of chronic aplastic anemia and the effect on T cell subsets and the expression of T-box expressed in T cells （T-bet） and GATA binding protein 3 （GATA3）. MethodA total of 585 patients with chronic aplastic anemia who were treated in 19 hospitals in China from May 2018 to June 2021 were enrolled. With the prospective， double-blind and randomized control methods， the patients were randomized into three groups： kidney deficiency group， Qi and blood deficiency group， and control group. The three groups were respectively treated with Bushen Shengxue prescription granule， Yiqi Yangxue prescription granule， and Placebo （half the dose of Bushen Shengxue formula granules）. In addition， all of them were given oral cyclosporin and androgen. The treatment lasted 6 months， with 3 months as a course. The blood routine indexes， T cell subsets， and fusion genes T-bet and GATA3 before and after treatment were analyzed， and the safety indexes were monitored. ResultDuring the observation， a total of 75 cases dropped out and 18 were rejected. Finally， 161 cases in the kidney deficiency group， 164 in the Qi and blood deficiency group， and 167 in the control group were included. After 6 months of treatment， the total effective rate was 98.8% （159/161） in the kidney deficiency group， which was higher than the 79.9% （131/164） in the Qi and blood deficiency group （χ²=30.135， P<0.01） and the 61.7% （103/167） in the control group （χ²=70.126， P<0.01）. The total effective rate was higher in the Qi and blood deficiency group than in the control group （χ²=13.232， P<0.01）. After treatment， the hemoglobin （HGB） content increased significantly in three groups （P<0.05） as compared with that before treatment， particularly the kidney deficiency group （P<0.01）. After treatment， the white blood cell （WBC） count and platelet （PLT） count in the kidney deficiency group and the control group increased compared with those in the Qi and blood deficiency group （P<0.01）. There was no specific difference in neutrophils （ANC） after treatment among the three groups. At the same time point， the level of T helper type 1 （Th1） cells， Th1/Th2 ratio （P<0.05）， level of CD4⁺， and CD4⁺/CD8⁺ ratio （P<0.05） were significantly low in the kidney deficiency group among three groups. There was no significant difference in CD19^-， HLA/DR⁺， and CD25⁺ between the kidney deficiency group and the other two groups， but the T-bet of the kidney deficiency group and the control group was lower than that of the Qi and blood deficiency group （P<0.05）. ConclusionBushen Shengxue prescription exerts therapeutic effect on the aplastic anemia by improving the immunoregulatory mechanism， inhibiting the activity of immune system， modulating T cell subsets， suppressing Th1 and CD4⁺， and promoting bone marrow hematopoiesis. Moreover， it is safe with little side effects， which is worthy of further promotion.
