Objective To explore the effects of long non-coding RNA LINC01772 on cell cycle,apoptosis and radiotherapy sensitivity of A549.Methods A549 cells were resuscitated and cultured for experimental pur-pose.The effects of LINC01772 knockdown on cell viability,cell cycle progression,and apoptosis were assessed using CCK-8 assays and flow cytometry,and apoptosis-related proteins were analyzed using western blotting.CCK-8 and clonogenic assays were used to measure the changes in the sensitivity of A549 cells to radiotherapy following various radiation doses,and flow cytometry to examine alterations in the cell cycle and apoptosis post-radiation treatment.Results Following lentiviral transfection that reduced LINC01772 levels in A549 cells,a significant decrease in cell viability(P<0.01)was observed alongside an increase in apoptosis(P<0.01).Notably,expres-sions of Bad and Cleaved Caspase-3 were significantly elevated(P<0.01),while Bcl-2 expression was markedly decreased(P<0.01).After exposure to different radiation doses,a dose-dependent reduction in A549 cell viability was noted(P<0.01),accompanied by a significant impairment of clonogenic ability(P<0.01),G2/M phase arrest within the cell cycle(P<0.01),and an increased incidence of apoptosis(P<0.01).Conclusion Inhibiting long non-coding RNA LINC01772 expression substantially diminishes cellular viability in A549 cells,enhances apoptotic processes,disrupts their cycling mechanisms,and augments their sensitivity to radiotherapy,suggesting that this non-coding RNA may serve as a potential target for enhancing lung cancer radiotherapy.

Objective:To analyze the current status of clinical trials of Chinese materia medica for the purpose of registration in China; To provide reference for the research and development of new TCM drugs.Methods:Clinical trials of Chinese materia medica/natural medicine registered in Drug Clinical Trial Registration and Information Disclosure Platform were retrieved from inception to December 31, 2024. Excel 2019 software was used to input and analyze the data such as the number of registered clinical trials, date of first publication, study status, field of indication, trial phases, sponsors, group leader, and design types.Results:A total of 1 137 Chinese materia medica clinical trials had been registered, accounting for 4.12% of the total number registered on the platform. Phase Ⅱ clinical trials accounted for the highest proportion (58.8%), and 99.7% of clinical trials conducted domestically. The sponsors were predominantly domestically pharmaceutical enterprises. These 1 137 clinical trials of Chinese materia medica clinical trials involved 752 drug categories, 28 dosage forms, and 796 varieties (the same class of drugs had different drug dosage forms), with capsules being the most common. The indications primarily focused on respiratory, digestive, cardio-cerebrovascular, neuropsychiatric, gynecological diseases. The group leader of clinical trials was distributed in 28 provinces, among which the First Teaching Hospital of Tianjin University of Traditional Chinese Medicine as the group leader, undertook the most clinical trials of TCM. 89.9% of the clinical trials adopted the randomized controlled trial design, and only 31.9% of the clinical trials purchased insurance for the subjects.Conclusion:The research and development of new TCM drugs has entered a phase of vigorous development. Further efforts are still needed in establishing systematic guidelines for Chinese materia medica clinical trials, accelerating the internationalization of TCM, exploring innovative dosage forms and indications, and strengthening the protection of participants' rights.

Ovarian cancer is the most lethal malignancy affecting the female reproductive system. Pharmacological inhibitors targeting CDK4/6 have demonstrated promising efficacy across various cancer types. However, their clinical benefits in ovarian cancer patients fall short of expectations, with only a subset of patients experiencing these advantageous effects. This study aims to provide further clinical and biological evidence for antineoplastic effects of a CDK4/6 inhibitor (TQB4616) in ovarian cancer and explore underlying mechanisms involved. Patient-derived ovarian cancer organoid models were established to evaluate the effectiveness of TQB3616. Potential key genes related to TQB3616 sensitivity were identified through RNA-seq analysis, and TRIM4 was selected as a candidate gene for further investigation. Subsequently, co-immunoprecipitation and GST pull-down assays confirmed that TRIM4 binds to hnRNPDL and promotes its ubiquitination through RING and B-box domains. RIP assay demonstrated that hnRNPDL binded to CDKN2C isoform 2 and suppressed its expression by alternative splicing. Finally, in vivo studies confirmed that the addition of siTRIM4 significantly improved the effectiveness of TQB3616. Overall, our findings suggest that TRIM4 modulates ubiquitin-mediated degradation of hnRNPDL and weakens sensitivity to CDK4/6 inhibitors in ovarian cancer treatment. TRIM4 may serve as a valuable biomarker for predicting sensitivity to CDK4/6 inhibitors in ovarian cancer.

OBJECTIVE To analyse the prognosis and laryngeal function retention of patients undergoing minimally invasive and open surgery after induction chemotherapy.METHODS The clinical data of 54 hypopharyngeal carcinoma patients who received induction chemotherapy and underwent laryngeal preservation surgery in Beijing Tongren Hospital from 2016 to 2022 were retrospectively analyzed.The laryngeal function recovery and survival rate were compared between the two groups.RESULTS Twenty-eight patients underwent transoral minimally invasive surgery and 26 patients underwent partial laryngectomy and/or partial laryngectomy via external cervical approach.The 3-year survival rates of the two groups were 63%and 59%,respectively,and the difference was not statistically significant(P＞0.05).The differences were statistically significant(P＜0.05).CONCLUSION In patients with downstaged hypopharyngeal carcinoma after induction chemotherapy,the survival rate of transoral minimally invasive surgery is similar to that of open surgery,and the laryngeal function recovery of transoral minimally invasive surgery is better.

At present, there is still no stomatology specialty in the training system of clinical pharmacists in China and the relevant research is still blank. The development of stomatological clinical pharmacy is also slow due to the lack of clinical pharmacists. By analyzing the national oral health policies, the characteristics of oral diseases and the clinical needs of stomatology, this paper provides theoretical basis for the setting of clinical pharmacist training specialty of stomatology specialty in China. This paper also makes a preliminary discussion on the construction of the training system of clinical pharmacists in the specialty of stomatology, so as to provide advice and references for the design and specific plan of the training system in the specialty of stomatology.

Hypervirulent Klebsiella pneumoniae (HvKP) is a new variant of Klebsiella pneumoniae. It is characterized by strong virulence and easy dissemination. It mainly causes liver abscess with multiple invasive infections, including eye, lung and central nervous system, with a high fatality rate. A case of severe intracranial infection caused by HvKP was reported. The patient was a 44-year-old formerly healthy man. He had acute onset of fever, headache, and disturbance of consciousness, which rapidly progressed to intracranial hypertension and respiratory failure. Cerebrospinal fluid examination suggested purulent infection, and bacterial culture suggested Klebsiella pneumoniae, which was sensitive to other commonly used antibiotics except ampicillin. Brain magnetic resonance imaging showed multiple abnormal signals in bilateral frontal, parietal and temporal lobes, right centrum semiovale, bilateral corona radiata, basal ganglia, thalamus and insula, as well as enhancement of meningeal and ependymal membrane, and swelling of brain tissue. During hospitalization, the patient developed a blood stream infection of pan-drug-resistant Klebsiella pneumoniae and was in critical condition. After aggressive treatment, the patient was cured and discharged from the hospital. After half a year follow-up, his prognosis was good and his social function was restored. The clinical data, diagnosis and treatment of the patient were reported and the literature was reviewed to provide clinical reference for the disease.

Objective: To explore imaging characteristics of children with 2019 novel coronavirus (2019-nCoV) infection. Methods: A retrospective analysis was performed on clinical data and chest CT images of 15 children diagnosed with 2019-nCoV. They were admitted to the third people’s Hospital of Shenzhen from January 16 to February 6, 2020. The distribution and morphology of pulmonary lesions on chest CT images were analyzed. Results: Among the 15 children, there were 5 males and 10 females, aged from 4 to 14 years old. Five of the 15 children were febrile and 10 were asymptomatic on first visit. The first nasal or pharyngeal swab samples in all the 15 cases were positive for 2019-nCoV nucleic acid. For their first chest CT images, 6 patients had no lesions, while 9 patients had pulmonary inflammation lesions. Seven cases of small nodular ground glass opacities and 2 cases of speckled ground glass opacities were found. After 3 to 5 days of treatment, 2019-nCoV nucleic acid in a second respiratory sample turned negative in 6 cases. Among them, chest CT images showed less lesions in 2 cases, no lesion in 3 cases, and no improvement in 1 case. Other 9 cases were still positive in a second nucleic acid test. Six patients showed similar chest CT inflammation, while 3 patients had new lesions, which were all small nodular ground glass opacities. Conclusions The early chest CT images of children with 2019-nCoV infection are mostly small nodular ground glass opacities. The clinical symptoms of children with 2019-nCoV infection are nonspecific. Dynamic reexamination of chest CT and nucleic acid are important.

Cervicitis is a common infectious disease of female reproductive system. As a portal to the uterus and pelvic cavity, cervical tube has a certain protective effect. When the inflammation spreads upward, it can not only affect the normal pregnancy and cause many adverse pregnancy outcomes, such as infertility, abortion, premature birth, premature rupture of membranes and reproductive failure, but also can cause neonatal infection, even neonatal death. The clinical treatment of cervicitis can improve pregnancy, mainly about physical therapy and drug therapy, but the prognosis and potential impact of various intervention methods on female cervical infection are not the same. Therefore, it is particularly critical to adopt active and appropriate treatment. This paper discusses the effects of cervicitis and different treatment methods on pregnancy outcome and assisted reproduction technology as to provide reference for the treatment of related diseases in clinic.
