Objective To investigate the expansion margins of the planning target volume (PTV) and the planning organ at risk volume (PRV) in nasopharyngeal carcinoma patients immobilized with Styrofoam and head-neck-shoulder mask. Methods A convenient sample of 33 nasopharyngeal carcinoma patients who received radiotherapy at Huanggang Central Hospital from January to October 2024 were selected as the research subjects. All patients underwent cone beam CT scans during the first three treatments and weekly thereafter. After registration and calibration, the setup errors in the X (LAT), Y (LNG), and Z (VRT) directions were recorded. Statistical analysis was performed on the setup errors in each direction to determine differences, and the expansion margins for PTV and PRV were calculated using empirical formulas. Results A total of 229 cone beam CT images were collected. Statistical analysis found that the setup errors (systematic error ± random error) of the patients in the X, Y, and Z directions were 1.05 ± 0.72, 1.30 ± 0.80, and 1.29 ± 0.82 mm, respectively. The expansion margins for PTV in the left-right, superior-inferior, and anterior-posterior directions were 1.40, 1.76, and 1.8 mm, respectively. The expansion margins for PRV in these directions were 0.83, 1.02, and 1.05 mm, respectively. Conclusion For patients immobilized using Styrofoam and head-neck-shoulder mask, it is recommended that the expansion margins for PTV and PRV be set at 2 mm and 1 mm, respectively, in the left-right, superior-inferior, and anterior-posterior directions, and the PRV margin for the spinal cord be set at 3 mm in all directions.

italic>Salvia miltiorrhiza, a commonly used traditional Chinese medicine, has been widely recognized for its blood-activating and stasis-removing properties in the clinical treatment of cardiovascular and cerebrovascular diseases. The synthesis and regulatory mechanism of tanshinones, the key active constituents of Salvia miltiorrhiza, have been a hot topic of research. The paper summarized the research findings on the regulation of tanshinone biosynthesis by transcription factors such as AP2/ERF, bHLH, MYB, bZIP, and WRKY in recent years. The review identifies the existing issues in the transcriptional regulation studies of Salvia miltiorrhiza and discusses the research direction of transcription factors in the regulation of tanshinone biosynthesis, providing a theoretical basis for the further discovery and utilization of functional genes involved in the regulation of tanshinone bioactive constituents.

[Objective] To summarize the clinical manifestations, pathological characteristics, treatment options and prognosis of the world's first case of prostate ductal adenocarcinoma (PDA) complicated with prostate mucinous adenocarcinoma (PMA). [Methods] The clinical and follow-up data of a patient with PDA and PMA treated in Zhongnan Hospital of Wuhan University were retrospectively analyzed, and relevant literature in PubMed and CNKI databases was retrieved. [Results] The patient sought medical attention due to dysuria, frequent urination, urinary urgency and urinary pain for more than half a year, and was admitted to hospital 3 times in total.The initial diagnosis upon the first admission was benign prostatic hyperplasia complicated with prostatic abscess.After 2 months, the patient was readmitted due to worsening symptoms, received transurethral bladder neck incision+ cystoscopy+ transurethral plasma resection of the prostate, and postoperative diagnosis confirmed PDA with local PMA.Three months after surgery, the patient had bleeding.After auxiliary examinations revealed extensive metastasis, he received hormonal therapy.After 9 months, the patient died due to multiple lung metastases. [Conclusion] Early diagnosis has a significant impact on the treatment and prognosis, but there have been no previous reports of PDA combined with PMA, so the lack of specific biomarkers in the early stage has led to missed diagnosis or misdiagnoses.There is no specific treatment for PDA with PMA. Radical prostatectomy was not satisfactory in the treatment of this case.

OBJECTIVE To investigate the effect and potential mechanism of sodium ferulate （SF） on corneal endothelial dysfunction and corneal endothelial cell （CEC） injury. METHODS The male New Zealand rabbits were divided into control group， benzalkonium chloride （BAK） group and BAK+SF group， with 6 rabbits in each group. Except for control group， the other groups were given BAK into the anterior chamber to induce bullous keratopathy model， and BAK+SF group then given SF solution 200 mg/kg intraperitoneally the next day after surgery， twice a day， for consecutive 14 d. The transparency of corneal and edema of corneal stroma in each group of rabbits （before and on the 1st， 7th， and 14th day after surgery） were observed， and the corneal thickness （14th day after surgery） and intraocular pressure （1st to 14th day after surgery） were measured. On the 14th day after operation， the corneal endothelial structure was evaluated and the expressions of functionally related proteins [phalloidin， zonula occludens-1 （ZO-1）， Na+/K+-ATPase， Ki67] were detected. On the 14th day after surgery， the corneal tissue was collected in BAK group， the primary rabbit CECs were isolated and cultured， and they were divided into blank group and SF groups with different mass concentrations. The cell viabilities after being cultured for different time， and the protein expressions of Ras homologous gene family A （RhoA）， bone morphogenetic protein receptor 1A （BMPR1A） and BMRP2 were determined in each group. RESULTS Compared with BAK group， the transparency of corneal and edema of corneal stroma were gradually improved， and the corneal thickness was significantly decreased in BAK+SF group （P＜0.05）. The rabbit CECs in BAK+SF group were only damaged to zone B and showed a normal hexagonal endothelial cells structure. The protein expressions of phalloidin， ZO-1， Na+/K+-ATPase and Ki67 in BAK+SF group were significantly increased （P＜0.05）. When SF concentration was lower than and equal to 200 mg/L， it could promote the proliferation of rabbit CEC， in concentration manner （P＜0.05） and time-dependent trend. SF at concentrations of 50， 100， and 200 mg/L could up-regulate the protein expressions of RhoA， BMPR1A and BMPR2 in concentration-dependent manner （P＜0.05）. CONCLUSIONS SF can improve the transparency of corneal and edema of corneal stroma in bullous keratopathy model rabbits， reduce corneal thickness， maintain the integrity of corneal endothelium structure， and promote the recovery of corneal endothelial function； this compound can promote the proliferation of CEC， the mechanism of which may be related to the activation of RhoA-ROCK-BMP pathway.

Prunellae Spica is the dry ear of the labiaceae plant Prunella vulgaris， which is a traditional medicine and food plant with many functions. Prunellae Spica can clear liver-fire， improve eyesight， disperse knot detumescence. It owns hot and bitter flavors and cold property. It goes to the liver， gallbladder meridian， and is a kind of commonly-used antifebric. Prunellae Spica has been used in the treatment of mammary gland diseases since ancient times.The mammary abscess， mammary nodules， mammary carcinoma of traditional Chinese medicine all belong to breast disease， and the liver meridian is most closely related to these diseases. With the development of social life， breast disease has gradually become the most primary health problem for women. Modern pharmacological studies show that Prunellae Spica contains terpenoids， phenolic acids， flavonoids and other biological active components， which have anti-inflammatory， antibacterial， hormone regulation， anti-tumor and other effects. Prunellae Spica inhibits the p38 mitogen-activated protein kinase （p38 MAPK）/nuclear factor kappa-B （NF-κB） pathway to play an anti-mastitis role， interferes with the effects of estrogen receptors or regulates lipid levels to treat breast hyperplasia， and treats breast cancer through promoting the apoptosis of breast cancer cells， inhibiting the migration of breast cancer cells， regulating the division of breast cancer cells and other ways. While referring to the relevant literature， it was found that Prunellae Spica often exerted pharmacological effects through multi-channels and multi-target regulation， but most of the studies did not specify the specific target of its effect， which needs further study. In this review， the effects and mechanisms of Prunellae Spica in the treatment of various breast diseases were summarized， so as to provide a reference for further research on the wider clinical therapeutic effects of Prunella subtilis and its therapeutic effects on breast diseases.

Objective: To investigate the incidence and treatment of perioperative anemia in patients with gastrointestinal neoplasms in Hubei Province. Methods: The clinicopathological data of 7 474 patients with gastrointestinal neoplasms in 62 hospitals in 15 cities (state) of Hubei Province in 2019 were collected in the form of network database. There were 4 749 males and 2 725 females. The median age of the patients was 62 years (range: 17 to 96 years). The hemoglobin value of the first time in hospital and the first day after operation was used as the criterion of preoperative anemia and postoperative anemia. Anemia was defined as male hemoglobin <120 g/L and female hemoglobin <110.0 g/L, mild anemia as 90 to normal, moderate anemia as 60 to <90 g/L, severe anemia as <60 g/L. The t test and χ² test were used for inter-group comparison. Results: The overall incidence of preoperative anemia was 38.60%(2 885/7 474), and the incidences of mild anemia, moderate anemia and severe anemia were 25.09%(1 875/7 474), 11.37%(850/7 474) and 2.14%(160/7 474), respectively. The overall incidence of postoperative anemia was 61.40%(4 589/7 474). The incidence of mild anemia, moderate anemia and severe anemia were 48.73%(3 642/7 474), 12.20%(912/7 474) and 0.47%(35/7 474), respectively. The proportion of preoperative anemia patients receiving treatment was 26.86% (775/2 885), and the proportion of postoperative anemia patients receiving treatment was 14.93% (685/4 589). The proportions of preoperative anemia patients in grade ⅢA, grade ⅢB, and grade ⅡA hospitals receiving treatment were 26.12% (649/2 485), 32.32% (85/263), and 29.93% (41/137), and the proportions of postoperative anemia patients receiving treatment were 14.61% (592/4 052), 22.05% (73/331), and 9.71% (20/206). The proportion of intraoperative blood transfusion (16.74% (483/2 885) vs. 3.05% (140/4 589), χ²=434.555, P<0.01) and the incidence of postoperative complications (17.78% (513/2 885) vs. 14.08% (646/4 589), χ²=18.553, P<0.01) in the preoperative anemia group were higher than those in the non-anemia group, and the postoperative hospital stay in the preoperative anemia group was longer than that in the non-anemia group ((14.1±7.3) days vs. (13.3±6.2) days, t=5.202, P<0.01). Conclusions: The incidence of perioperative anemia in patients with gastrointestinal neoplasms is high. Preoperative anemia can increase the demand for intraoperative blood transfusion and affect the short-term prognosis of patients. At present, the concept of standardized treatment of perioperative anemia among gastrointestinal surgeons in Hubei Province needs to be improved.

To clarify the content characteristics of mineral elements in different Artemisia argyi germplasm resources and their relationship with the quality properties of Artemisiae Argyi Folium, this study measured the content of 10 mineral elements including nitrogen(N), phosphorus(P), potassium(K), calcium(Ca), magnesium(Mg), aluminum(Al), manganese(Mn), iron(Fe), copper(Cu), and zinc(Zn) in 100 Artemisia argyi germplasm samples. Besides, their relationship with the quality properties of Artemisiae Argyi Folium was explored by correlation analysis, path analysis, and cluster analysis. The results demonstrated that the variation coefficient of the 10 mineral elements in Artemisiae Argyi Folium ranged from 12.23% to 64.38%, and the genetic diversity index from 0.97 to 3.09. The genetic diversities of N, P, and Zn were obvious. As revealed by the correlation analysis, N, P, and K showed strong positive correlations with each other. Except that Mg and Al were negatively correlated, Ca, Mg, Al, Mn, Fe, Cu, and Zn were positively correlated. The correlation analysis of mineral elements with the quality properties of Artemisiae Argyi Folium proved the significant correlations of 17 pairs of characters. According to the path analysis, P, K, Ca, and Mn greatly affected the yield of Artemisiae Argyi Folium, P, K, and Mg the output rate of moxa, N, P, and K the content of total volatile oil, P and K the content of eucalyptol, and P, K, and Ca the content of eupatilin. The 100 germplasm samples were clustered into three groups. Specifically, in cluster Ⅰ, the enrichment capacity of P, K, and Mg elements was strong, and the comprehensive properties of mineral elements were better, implying good development potential. Ca, Mn, Fe, and Zn elements in cluster Ⅱ and N and Al in cluster Ⅲ displayed strong enrichment capacities. This study has provided new ideas for resource evaluation and variety breeding of A. argyi and also reference for fertilizer application.

Objective To forecast the future burden and its attributable risk factors of infective endocarditis (IE). Method We analyzed the disease burden of IE and its risk factors from 1990 to 2019 using the Global Burden of Disease 2019 database and projected the disease burden from 2020 to 2030 using a Bayesian age-period-cohort model. Results By 2030, the incidence of IE will increase uncontrollably on a global scale, with developed countries having the largest number of cases and developing countries experiencing the fastest growth. The affected population will be predominantly males, but the gender gap will narrow. The elderly in high-income countries will bear the greatest burden, with a gradual shift to middle-income countries. The incidence of IE in countries with middle/high-middle social-demographic indicators (SDI) will surpass that of high SDI countries. In China, the incidence rate and the number of IE will reach 18.07 per 100,000 and 451,596 in 2030, respectively. IE-associated deaths and heart failure will continue to impose a significant burden on society, the burden on women will increase and surpass that on men, and the elderly in high-SDI countries will bear the heaviest burden. High systolic blood pressure has become the primary risk factor for IE-related death. Conclusions This study provides comprehensive analyses of the disease burden and risk factors of IE worldwide over the next decade. The IE-associated incidence will increase in the future and the death and heart failure burden will not be appropriately controlled. Gender, age, regional, and country heterogeneity should be taken seriously to facilitate in making effective strategies for lowering the IE disease burden.

Objective To analyze the positive results of HIV antibody screening in the laboratory of AIDS confirmation center of Hubei Provincial Center for Disease Control and Prevention from 2014 to 2020, and to provide a basis for improving detection strategies. Methods A total of 2 728 primary screening positive specimens received by the laboratory of Hubei confirmation center from 2014 to 2020 were retested with two reagents. Specimens with at least one reactive result were confirmed with western blot (WB). The samples with uncertain or negative WB results were further confirmed by nucleic acid quantitative detection. The test results were analyzed retrospectively. Results A total of 2 297 specimens with positive retest results were confirmed by WB, with a positive rate of 93.47%. The highest proportion of patients was from medical institutions. The positive rate detected by 4 diagnostic kits was apparently higher in S/CO＞10 cases than that in S/CO≤10, and the difference was statistically significant (P < 0.05). Of the 19 samples with inconsistent results in ELISA, 1 was confirmed as positive by WB, while 12 were negative both by WB and nucleic acid detection. Among 68 samples with uncertain WB results, 49 cases had nucleic acid quantitative results > 5 000cps / ml, and 12 cases were TND. 13 of the 30 WB negative samples had nucleic acid test results＞5 000CPs/mL . Conclusions The coverage of HIV screening laboratories in hospitals at all levels should be further increased to find more HIV infected persons. The anti-HIV ELISA S/CO ratio is correlated with the positive results confirmed by western blot. Therefore, ELISA S/CO ratio can be used to predict anti-HIV antibody positivity. For samples with uncertain or negative WB detection, supplemental nucleic acid test should be carried out timely for early diagnosis.

[Abstract] Objective: To investigate the miR-423-5p expression in brain glioma tissues and cell lines, and its promotive effect on temozolomide (TMZ) chemoresistance by targeting PDCD5 (programmed cell death protein 5). Methods: Tumor tissues and matched peritumoral tissues were collected from 20 brain glioma patients who were surgically treated in the Department of Neurosurgery, Affiliated Hospital of Beihua University between January 2017 and December 2018. Glioblastoma cell lines (U251, U87, SHG-44) and human normal glial cell line HMC-3 were also used in the study. The relative expression of miR-423-5p and PDCD5 in brain glioma and peritumoral tissues and cell lines was detected by qPCR. The synthesized miR-423-5p mimics and miR-NC were respectively transfected into U251 and U87 cells; meanwhile, TMZ at different concentrations (50, 100, 150 and 200 μmol/L) were also used to treat the cells. Then, the chemoresistance of cells to TMZ were determined. MTT assay and colony formation assay were used to examine the proliferation of U251 and U87 cells, andWestern blotting was used to detect the expression of c-caspase 3, Bcl-2 and PDCD5 proteins in U251 and U87 cells. The targeting relationship between PDCD5 and miR-423-5p was validated through Dual luciferase reporter gene assay. Results: miR-423-5p was highly expressed in glioma tissues and glioma cell lines (all P<0.01). As compared with the miR-NC group, the proliferation and TMZ-chemoresistance of U251 and U87 cells in miR-423-5p mimics group significantly increased (all P<0.01). Dual luciferase reporter gene assay validated that miR-423-5p could bind with PDCD5 3' UTR to suppress the expression of PDCD5. Conclusion: High expression of miR-423-5p enhances the chemoresistance of glioma cells to TMZ, and miR-423-5p may serve as a potential therapeutic target in the treatment of brain glioma.
