OBJECTIVE: The aim of this study is to investigate the main active substances of Qilin pills by high performance liquid chromatogre-electrostatic field orbitrap mass spectrometry (HPLC-Q-Orbitrap /MS), and explore the mechanism of its action in the treatment of asthenozoospermia by combining network pharmacology and molecular docking. METHODS: (1) Qilin pills were quantitatively and qualitatively analyzed by HPLC-Q-Orbitrap /MS. (2) The top 100 compounds in Qilin pills were screened by content analysis and SwissADME, and their targets were predicted. The asthenozoospermia targets were searched through the database. And a "protein-protein interaction" (PPI) network was constructed. KEGG and GO analysis was performed using the DAVID database. And a "drug-target-pathway" network was constructed. (3) SailVina was used for molecular docking. RESULTS: (1) A total of 1 275 known components were found and ranked in Qilin pills by HPLC-Q-Orbitrap /MS analysis. (2) The top 100 compounds in Qilin pills predicted a total of 1 053 targets and 184 potential therapeutic targets for asthenozoospermia. KEGG pathway analysis and GO analysis showed that the treatment of asthenozoospermia by Qilin pills may be related to the steroid hormone synthesis pathway, the response to steroid hormones, the chromosomal region of cells and the activity of steroid hydroxylase. The mechanism of Qilin pills in treating asthenozoospermia may be related to regulating the synthesis, metabolism and reaction process of sex hormone in the body. (3) The molecular docking results of its key targets (CYP19A1, ESR1, HSP90AA1, p53, HIF1α and BCL2) showed that the key active ingredients M030, M039, M043, M050, M055 and M073 of Qilin pills had spontaneous binding. It had a binding energy of less than －5 kJ /mol. CONCLUSION The material basis of Qilin pills has been explored by this study. And the mechanism of action of Qilin pills in the treatment of asthenozoospermia is highly bound to the expression and response process of steroid hormones, which provides a theoretical basis for the clinical application of Qilin pills.

Objective: To investigate the clinicopathological features of perivascular epithelioid cell tumor (PEComa) of the lung. Methods: Eight PEComa cases of the lung diagnosed at the First Affiliated Hospital of Soochow University, Suzhou, China from July 2008 to December 2021 were collected and subject to immunohistochemical staining, fluorescence in situ hybridization and next generation sequencing. The relevant literature was reviewed and the clinicopathological features were analyzed. Results: There were 5 males and 3 females, aged from 18 to 70 years (mean 39 years). There were 3 cases of the right upper lung, 3 cases of the left lower lung, 1 case of the left upper lung and 1 case of the right middle lung. Seven cases were solitary and 1 case was multifocal (4 lesions). Seven cases were benign while one was malignant. The tumors were all located in the peripheral part of the lung, with a maximum diameter of 0.2-4.0 cm. Grossly, they were oval and well circumscribed. Microscopically, the tumor cells were oval, short spindle-shaped, arranged in solid nests, acinar or hemangiopericytoma-like patterns, with clear or eosinophilic cytoplasm. The stroma was rich in blood vessels with hyalinization. Coagulated necrosis and high-grade nuclei were seen in the malignant case, and calcification was seen in 2 cases. Immunohistochemically, the tumor cells were positive for Melan A (8/8), HMB45 (7/8), CD34 (6/8), TFE3 (4/7), and SMA (3/8). All cases were negative for CKpan and S-100. TFE3 (Xp11.2) gene fusion was examined using the TFE3 break-apart fluorescence in situ hybridization in 5 cases, in which only the malignant case was positive. The next generation sequencing revealed the SFPQ-TFE3 [t(X;1)(p11.2;p34)] fusion. Follow-up of the patients ranged from 12 to 173 months while one patient was lost to the follow-up. The malignant case had tumor metastasis to the brain 4 years after the operation and then received radiotherapy. Other 6 cases had no recurrence and metastasis, and all the 7 patients survived. Conclusions: Most of the PEComas of the lung are benign. When there are malignant morphological features such as necrosis, high-grade nuclei or SFPQ-TFE3 gene fusion, close follow-up seems necessary.

Objective: To explore the application of manual screening collaborated with the Artificial Intelligence TPS-Assisted Cytologic Screening System in urinary exfoliative cytology and its clinical values. Methods: A total of 3 033 urine exfoliated cytology samples were collected at the Henan People's Hospital, Capital Medical University, Beijing, China. Liquid-based thin-layer cytology was prepared. The slides were manually read under the microscope and digitally presented using a scanner. The intelligent identification and analysis were carried out using an artificial intelligence TPS assisted screening system. The Paris Report Classification System of Urinary Exfoliated Cytology 2022 was used as the evaluation standard. Atypical urothelial cells and even higher grade lesions were considered as positive when evaluating the recognition sensitivity, specificity, and diagnostic accuracy of artificial intelligence-assisted screening systems and human-machine collaborative cytologic screening methods in urine exfoliative cytology. Among the collected cases, there were also 1 100 pathological tissue controls. Results: The accuracy, sensitivity and specificity of the AI-assisted cytologic screening system were 77.18%, 90.79% and 69.49%; those of human-machine coordination method were 92.89%, 99.63% and 89.09%, respectively. Compared with the histopathological results, the accuracy, sensitivity and specificity of manual reading were 79.82%, 74.20% and 95.80%, respectively, while those of AI-assisted cytologic screening system were 93.45%, 93.73% and 92.66%, respectively. The accuracy, sensitivity and specificity of human-machine coordination method were 95.36%, 95.21% and 95.80%, respectively. Both cytological and histological controls showed that human-machine coordination review method had higher diagnostic accuracy and sensitivity, and lower false negative rates. Conclusions: The artificial intelligence TPS assisted cytologic screening system has achieved acceptable accuracy in urine exfoliation cytologic screening. The combination of manual screening and artificial intelligence TPS assisted screening system can effectively improve the sensitivity and accuracy of cytologic screening and reduce the risk of misdiagnosis.

Objective: To investigate the clinicopathological characteristics of primary pulmonary NUT carcinoma. Methods: A total of 7 cases of primary pulmonary NUT carcinoma were collected from Fujian Provincial Hospital (n=5), Fuzhou Taijiang Hospital (n=1) and Binzhou City People's Hospital of Shandong Province (n=1) from January 2021 to April 2023. The clinical, histopathological, and immunohistochemical features were analyzed, and NUT rearrangement were detected by fluorescence in situ hybridization (FISH) with break-apart probes. Results: Seven cases were all male with age ranging from 32 to 73 years. The main clinical manifestations were cough, expectoration and chest tightness. Microscopically, NUT carcinoma was composed of monotonous proliferation of primitive-appearing small-to-medium round cells, with few eosinophilic cytoplasm, arranged in solid sheets, nests or clusters. Abrupt keratinization was typically observed in 4 cases (4/7), with high mitotic activities and necrosis. Immunohistochemistry (IHC) showed that the tumors were positive for NUT (7/7), CK7 (4/4), CK5/6 (5/6), p40 (6/7). Ki-67 index were 30%-80%. NUT gene segregation (7/7) was detected by FISH break probes. Conclusions: Primary pulmonary NUT carcinoma is rare and highly malignant. Diagnosis depends on histopathology and IHC, with molecular detection as an adjunct for diagnosis. Pathologists should be aware of the clinicopathological characteristics to avoid misdiagnosis.

Objective: To investigate the prevalence of anxiety and depression among inpatients with AIDS and its influencing factors, so as to provide the evidence for improving the psychological health among inpatients with AIDS. Methods: The inpatients with AIDS that were hospitalized in an infectious disease hospital in Chengdu City were recruited using the convenient sampling method. The demographic features, depression and anxiety were collected using a self-designed questionnaire, Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale ( SDS ), respectively, and factors affecting the development of depression and anxiety were identified using a multivariable linear regression model among inpatients with AIDS. Results: The 228 AIDS inpatients included 186 men (81.58%) and 42 women ( 18.42% ), and had a mean age of ( 48.04±16.03 ) years. There were 113 inpatients ( 49.56% ) with a CD4+T cell count of ≤200 cells/μL, and the mean SAS and SDS standardized scores were 35.87±8.01 and 42.07±11.08 among AIDS inpatients, which were both significantly greater than in normal populations ( P<0.05 ). The prevalence rates of anxiety, depression, and comorbid anxiety and depression were 5.26%, 16.23% and 4.82% among the participants, respectively. Multivariable linear regression analysis identified unemployment as a risk factor of anxiety ( β'=0.168, P<0.05 ), and CD4+T cell count as a risk factor of anxiety ( β'=-0.151, P<0.05 ) and depression ( β'=-0.238, P<0.05 ) among inpatients with AIDS. Conclusions Anxiety and depression are prevalent among inpatients with AIDS. Unemployment and a low CD4+T cell count may cause a rise in the risk of developing anxiety and depression among inpatients with AIDS.

OBJECTIVE：To understand the current management situation and problems of residual drugs in medical institutions in China ，evaluate the practice effect of corresponding control mode of our hospital and to explore the countermeasures to reduce the production of residual drugs and standardize its management. METHODS ：By random sampling ，30 third-level hospitals and 20 second-level hospitals in different regions were selected respectively during May 1st to 31st in 2019. For the pharmaceutical personnel，doctors，nurses and other non-pharmaceutical personnel ，a self-designed questionnaire on the status quo of residual drugs in medical institutions was issued. Excel 2010 software was used to count basic data of valid questionnaire ，and the causes ， management status ，disposal status and possible hazards of residual drugs in medical institutions were analyzed. A management mode of residual drugs was established and implemented （involving reducing the generation of sources ，implementing process management，and strictly implementing disposal ）. The effects of the model were evaluated ，then the countermeasures and suggestions were put forward . RESULTS & CONCLUSIONS：A total of 400 questionnaires were sent out ，and 311 valid questionnaires were collected with effective recovery rate of 77.75％. The causes of drug residual were complicated ，which included the“combination”of the same drugs ，the pre-order dispensing ，adverse drug reactions ，poor compliance of patients ，wrong order imput，sudden transfer ，discharge or death of patients ，wrong dispensing or nurse check error ，etc. The management status of residual drugs was chaotic ，the disposal methods lacked of standardization ，which may lead to harm such as deterioration ，illegal Δ 基金项目：重庆市技术预见与制度创新项目（No.cstc2018jsyj- recycling and pollution .

According to the operation management practice from Jan. to Oct. 2018，a total of more than 1 million yuan worth of residual drugs were recovered. The residual drugs that did not meet the recovery conditions should be destroyed according to the specified process ，and the case number of non-standard notification of ward management would significantly reduced. The whole-link mode management established by our hospital can effectively reduce the production of residual drugs and standardize their management and disposal. It is suggested that the state or province should issue special regulations on the management of residual drugs in medical institutions ，and each medical institution should formulate specific management measures suitable for its own unit. Meanwhile ，the management of residual drugs in medical institutions should be further standardized systematically by actively exploring the ways to reduce residual drugs ，formulating the corresponding financial account processing standards ， supporting incentive mechanism and other measures.
