RESUMEN
Objective:To analyze the clinical characteristics of long-term survival patients with advanced non-small cell lung cancer (NSCLC) treated with chemotherapy combined with primary tumor radiotherapy, and to establish a Nomogram prognostic model, aiming to provide a certain reference for making a decision about the treatment of advanced NSCLC.Methods:A retrospective analysis was made on the data of 260 NSCLC patients who participated in two prospective clinical studies from January 2003 to May 2012 and the data of 138 NSCLC patients admitted to the Affiliated Cancer Hospital of Guizhou Medical University from January 2014 to August 2020. The former 260 cases were used as a training set and the latter 138 cases were used as the validation set. The overall survival (OS) of ≥ 18 months was defined as long-term survival (LTS). The clinical characteristics of LTS patients were compared with those with OS less than 18 months. The clinical characteristics and treatment-related parameters between the two types of patients were compared using the χ2 test. A multivariate analysis was made using logistic regression, and a nomogram model was built using RStudio. Results:The median OS of the training set was 13.4 months (95% CI: 11.9-14.9), with 1-, 2-, and 3-year OS rates of 55.4%, 19.1%, and 11.9%, respectively. In the training set, 87 cases had LTS and were classified as the LTS group, while 173 cases had OS less than 18 months and were classified as the non-LTS group. The univariate analysis showed that the prognostic factors affecting LST included the KPS score, T status, the number of metastatic organs, the number of metastatic lesions, brain metastasis, bone metastasis, the number of chemotherapy cycles, the biologically effective dose (BED) to the primary tumor, hemoglobin level, platelet count, plasma D-dimer, fibrinogen level, lactate dehydrogenase, and lung immune prognostic index (LIPI; χ2=4.72-12.63, P < 0.05). The multivariable analysis showed that the independent prognostic factors of LTS included a number of chemotherapy cycles ≥ 4, BED ≥ 70 Gy, platelets ≤ 220×10 9/L, D-dimer ≤ 0.5 mg/L, and a good LIPI score ( P= 0.002, 0.036, 0.005, 0.008, and 0.002). A nomogram model was established using the meaningful parameters obtained in the multivariable analysis, determining that the training and validation sets had a consistency index (C-index) of 0.750 and 0.727, respectively. As shown by the analytical result of the corrected curves, for the advanced NSCLC patients treated with thoracic radiotherapy, their LTS probability predicted using the nomogram prognostic model was highly consistent with their actual LTS probability. Both the analytical result of the receiver operating characteristic (ROC) curves and the decision curve analysis (DCA) result showed that the composite prediction model was more beneficial than a single prediction model. Conclusions:For patients with advanced NSCLC treated with thoracic radiotherapy, the independent prognostic factors of LTS included the number of chemotherapy cycles, BED, platelet count, pre-chemotherapy D-dimer, and LIPI score. The Nomogram prognostic model built based on these prognostic factors is a convenient, intuitive, and personalized prediction model used to screen patients who can benefit from thoracic radiotherapy.
RESUMEN
Objective:To analyze the frequency and characteristics of polymyositis (PM) in idiopathic inflammatory myopathy (IIM), and to investigate whether PM is over-diagnosed.Methods:Patients diagnosed as IIM according to the Bohan & Peter criteria of IIM hospitalized in the Department of Rheumatology of China-Japan Friendship Hospital from 2008 to 2019 were involved in the study. Definite PM (dPM) was defined as typical clinical and pathological features including elevated creatine kinase (CK) level, muscle weakness and muscle biopsy findings with endomysial CD8 + T cell infiltration and expression of MHC-1 on sarcolemma. Meanwhile, dermatomyositis (DM), anti-synthase syndrome(ASS), immune-mediated necrotic myopathy(IMNM), sporadic inclusion body myositis(sIBM) and other myopathies were excluded according to the new classification criteria of IIM subtypes respectively. Statistical analysis was performed using SPSS software 24.0. The Kruskal-Wallis test and χ2 test were used to compare the clinical characteristics between the dPM group and other IIM subtypes. Results:A total of 1 259 patients with IIM including 1 015 (80.6%) DM and 244(19.4%) PM were enrolled in this study. According to the strict definition of PM criteria, only 0.5% of patients (6/1 259) in IIM could be diagnosed as dPM. Most PM patients were IMNM and ASS according to the new IIM subtypes criteria, of which 48.0% (117/244) were IMNM and 32.0% (78/244) were ASS. 66.7%(4/6) of dPM patients were women. One complicated with RA, and one was dPM overlaped with systemic sclerosis. All of them had muscle weakness, mild elevation of CK level [611(391,1 451) U/L], and were myositis-specific autoantibodies negative. Except one dPM patients who did not receive immunoregulatory therapy due to chronic obstructive pulmonary disease, the others were administrated with low or medium dose prednisone combined with or without immunosuppressive agents. After a median follow-up of (38±26) months, the muscle strength of dPM patients were improved.Conclusion:dPM is a very rare clinical subtype of IIM. PM is an over-diagnosed entity in clinical practice. Patients with dPM have mild symptoms and good outcome.

Objective:To investigate the value of the ultrasonography in the diagnosis of the white matter injury of premature infants based on gray-scale ultrasonography radiomics.Methods:A total of 256 premature infants in Huazhong University of Science and Technology Union Shenzhen Hospital and Shenzhen Hospital of Southern Medical University from August 2018 to April 2022 were analyzed retrospectively. The computer-generated random numbers were assigned to the training set and the verification set according to 6∶4 ratio. On the basis of standardized collection of craniocerebral ultrasound images, the radiomics features were extracted from imaging by Pyradiomics 3.0.1 software package, the Mann-Whitney U test and the least absolute shrinkage and selection operator (LASSO) and stepwise regression were used to select the optimal features. Then the Logistic regression was used to build radiomics model. According to MRI, ROC curve was utilized to evaluate the performance of the model. The craniocerebral ultrasound images in the validation set were independently diagnosed by a senior physician and a junior physician, and then the above two physicians diagnosed again with the help of the radiomics, and the diagnostic abilities of this model were compared with those of the junior and senior physicians with and without radiomics assist. Results:A total of 5 optimal features were selected to develop radiomics model. The sensitivity, specificity, accuracy and the area under the ROC curve (AUC) in the training and validation sets were 0.861, 0.775, 0.799, 0.818; 0.929, 0.824, 0.853, 0.876, respectively. The sensitivity, specificity, accuracy and AUC in the senior sonographer, the junior sonographer, and both of them with radiomics assist for the dagnosis in the validation set were 0.929, 0.892, 0.902, 0.910; 0.714, 0.743, 0.735, 0.729; 0.929, 0.919, 0.922, 0.924; 0.857, 0.824, 0.833, 0.841, respectively. Performance of radiomics model reached the level of the senior sonographer (AUC: 0.876 vs 0.910, P=0.284), which was significantly better than the performance of the junior sonographer(AUC: 0.876 vs 0.729, P=0.001). Performance of the junior sonographer with radiomics assist was significantly better than the performance of the junior sonographer(AUC: 0.841 vs 0.729, P=0.003). Performance of the senior sonographer with radiomics assist was comparable to that of the senior sonographer(AUC: 0.924 vs 0.910, P=0.156). Conclusions:The ultrasound diagnosis method based on radiomics technology shows good diagnostic performance for the white matter injury of premature infants. It is helpful to improve the diagnostic ability of junior sonographer. It is expected to assist the sonographers in diagnosis and provide objective, consistent and accurate results for clinical practice.
RESUMEN
During coronavirus disease 2019 epidemic, the treatment of severe trauma has been impacted. The Consensus on emergency surgery and infection prevention and control for severe trauma patients with 2019 novel corona virus pneumonia was published online on February 12, 2020, providing a strong guidance for the emergency treatment of severe trauma and the self-protection of medical staffs in the early stage of the epidemic. With the Joint Prevention and Control Mechanism of the State Council renaming "novel coronavirus pneumonia" to "novel coronavirus infection" and the infection being managed with measures against class B infectious diseases since January 8, 2023, the consensus published in 2020 is no longer applicable to the emergency treatment of severe trauma in the new stage of epidemic prevention and control. In this context, led by the Chinese Traumatology Association, Chinese Trauma Surgeon Association, Trauma Medicine Branch of Chinese International Exchange and Promotive Association for Medical and Health Care, and Editorial Board of Chinese Journal of Traumatology, the Chinese expert consensus on emergency surgery for severe trauma and infection prevention during coronavirus disease 2019 epidemic ( version 2023) is formulated to ensure the effectiveness and safety in the treatment of severe trauma in the new stage. Based on the policy of the Joint Prevention and Control Mechanism of the State Council and by using evidence-based medical evidence as well as Delphi expert consultation and voting, 16 recommendations are put forward from the four aspects of the related definitions, infection prevention, preoperative assessment and preparation, emergency operation and postoperative management, hoping to provide a reference for severe trauma care in the new stage of the epidemic prevention and control.
RESUMEN
Objective:To observe the efficacy of self-help cognitive behavioral therapy for insomnia (CBTI), trazodone hydrochloride and their combination in the treatment of depression and insomnia comorbidity in the elderly.Methods:90 elderly patients with insomnia and depression admitted to the 901th Hospital of the Joint Logistic Support Force from October 2019 to October 2021 were selected as the study subjects. They were divided into trazodone group, CBTI group and trazodone combined with CBTI group(combination group), with 30 cases in each group. Trazodone group was treated with oral trazodone hydrochloride, CBTI group was treated with self-help CBTI, and the combination group was treated with oral trazodone hydrochloride combined with self-help CBTI. All three groups were treated for 4 weeks. The sleep latency, total sleep time and sleep efficiency of each group were compared at the time of admission and after 4 weeks of treatment. Pittsburgh Sleep Quality Index (PSQI) and Epworth Sleepiness Scale (ESS) were used for sleep assessment before and after treatment, and Self-Rating Depression Scale (SDS) was used for depression assessment.Results:Before treatment, there was no significant difference among the three groups in terms of sleep latency, total sleep time, sleep efficiency, PSQI, ESS and SDS (all P>0.05). After treatment, the sleep latency of the three groups was shorter than that before treatment, and the total sleep time was longer than that before treatment (all P<0.05). The sleep efficiency of the trazodone group and the combination group was higher than that before treatment, with statistically significant difference (both P<0.05). The indexes of the combined group were better than those of the trazodone group and the CBTI group (all P<0.05). The sleep latency of the trazodone group was shorter than that of the CBTI group, and the total sleep time was longer than that of the CBTI group (all P<0.05), with statistically significant difference (all P<0.05). After treatment, the PSQI, except for the SDS of CBTI group, the ESS and SDS of the three groups were lower than those before treatment (all P<0.05). The PSQI, ESS and SDS of the combined group were lower than those of the trazodone group and the CBTI group, and the ESS and SDS of the trazodone group were lower than those of the CBTI group, with statistically significant difference (all P<0.05). Conclusions:For the elderly patients with depression and insomnia, the combination of self-help CBTI and trazodone can not only improve insomnia but also relieve depression symptoms, and the effect is better than that of trazodone and self -help CBTI alone.

RESUMEN
【Objective】 To investigate the cell death-inducing effect of methyl rosmarinate (MR) on human hepatoma Hep-3B and SK-Hep1 cells and their potential mechanisms. 【Methods】 The effects of MR on the viability of Hep-3B, SK-Hep1 and MIHA cells were determined by cell counting kit-8 (CCK-8) assay. The morphological changes of three kinds of cells treated with different concentrations of MR were observed by optical microscopy. EdU assay and flow cytometry were used to detect the proliferation and apoptosis of Hep-3B and SK-Hep1 cells. Transwell assay was used to study the effects of MR on the migration and invasion of Hep-3B and SK-Hep1 cells. Western blotting was used to evaluate the protein expression levels of apoptosis, EMT and Akt/mTOR signaling pathways. 【Results】 After treated with different concentrations of MR (0~200 μmol/L) for 48 h, Hep-3B and SK-Hep1 cells activities were significantly decreased in a concentration-dependent manner (P<0.01), while there was no significant effect on MIHA cell activity (P>0.05), and the IC50 of Hep-3B and SK-Hep1 cells were 102.5 and 99.3 μmol/L, respectively. MR treatment (0-150 μmol/L) significantly inhibited the proliferation of Hep-3B and SK-Hep1 cells (P<0.05), while cell detachment and shrinkage were observed by optical microscopy on the Hep-3B and SK-Hep1 cells, while the morphology of MIHA cells was not changed. Compared with the control group, MR (100, 150 μmol/L) induced apoptosis in Hep-3B and SK-Hep1 cells, the expression levels of the pro-apoptotic proteins Bax and cleaved PARP were significantly increased (P<0.05), while the expression level of the anti-apoptotic protein Bcl-2 was significantly decreased (P<0.05). MR (100, 150 μmol/L) also inhibited the migration and invasion of HCC cells, significantly increased the expression of E-cadherin and decreased the expression of N-cadherin and Vimentin compared with the control group (P<0.05). Finally, Western blotting results showed that the expressions of p-Akt and p-mTOR in Hep-3B and SK-Hep1 treated by MR were significantly reduced in a dose-dependent manner, suggesting that MR may play an anti-cancer role by inhibiting Akt/mTOR signaling pathway. 【Conclusion】 MR can promote apoptosis in Hep-3B and SK-Hep1 cells, which may be closely related to the inhibition of Akt/mTOR signaling pathway.
RESUMEN
Objective To preliminarily study the effectiveness and safety of stereotactic ablative brachytherapy (SABT) for lung metastases from cervical cancer. Methods We analyzed the clinical data of 18 patients with cervical cancer with lung metastasis treated with SABT to compare gross tumor volume (VGTV) and squamous cell carcinoma (SCC) antigen before and after SABT. The clinical benefit rate (CBR) and adverse reactions were recorded. Results After SABT treatment, there were significant decreases in VGTV (t=1.708, P<0.05) and the SCC antigen level (t=1.704, P<0.05). CBR reached 94.4%. Adverse reactions of grades 3-4 did not occur in any patient. Fourteen patients had mild complications, including 1 case of bloody sputum and 1 case of a small pneumothorax. Ten cases developed mild radiation-induced lung injury, with grade 2 radiation pneumonitis in 4 cases. The Karnofsky performance status score and needle depth were not associated with the occurrence of adverse reactions, while the radius of GTV and interstitial lung disease were associated with the occurrence of adverse reactions. Conclusion SABT is a safe and effective alternative to the treatment of lung metastases from cervical cancer.
RESUMEN
Background/Aims@#In patients with acute nonvariceal upper gastrointestinal bleeding (ANVUGIB), the optimal timing of endoscopy is still a matter of dispute. We conducted a systematic review and meta-analysis to determine the clinical benefit of early endoscopy. @*Methods@#A literature search of the MEDLINE, Embase, and Cochrane databases was conducted to identify publications from inception to March 1, 2022. Eligible studies included observational cohort studies and randomized controlled trials that reported clinical outcomes of endoscopy in patients with ANVUGIB. ANVUGIB patients who underwent endoscopy within 24 hours of admission were considered to have had an early endoscopy. The primary outcome was the mortality rate in ANVUGIB patients who had early or nonearly endoscopy. @*Results@#The final analysis included five randomized controlled studies (RCTs) and 20 observational studies from the 1,206 identified articles. The mortality rate was not significantly reduced among patients who received endoscopy performed within 24 hours, whether in cohort studies nor in RCTs. For subgroup analysis, a higher mortality rate was found only among patients who received very early endoscopy within 12 hours (odds ratio, 1.66; p<0.001, I 2 =0) in cohort studies. No significant difference in mortality rates was found among patients at high risk of bleeding who received early versus nonearly endoscopy. @*Conclusions@#Early endoscopy within 24 hours does not appear to significantly reduce the mortality rates of patients with ANVUGIB. Further well-designed studies are warranted to address if very early endoscopy within 12 hours can provide a clinical benefit for patients at high risk of bleeding.
RESUMEN
Objective:To investigate the potential function and related mechanism of microRNA-223 (miRNA-223) in the podocyte pyroptosis of hepatitis B virus (HBV)-associated glomerulonephritis induced by HBV X protein (HBx).Methods:HBx-overexpressing lentivirus was transfected into human renal podocytes to mimic the pathogenesis of HBV-GN. Real-time fluorescence quantitative PCR and Western blotting experiments were used to detect the mRNA and protein expression of pyroptosis-related proteins [nucleotide-binding oligomerization domain-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC) and caspase-1], and inflammatory factors (interleukin-1β and interleukin-18), respectively.TUNEL staining and flow cytometry were used to detect the number of pyroptosis cells. Immunofluorescence staining was used to detect the expression of podocytes biomarkers desmin and nephrin; Hoechst 33342 staining was used to observe the morphological and quantitative changes of podocyte nuclei. Enzyme-linked immunosorbent assay was used to measure caspase-1 activity. The dual luciferase reporter gene assay was used to verify the downstream target of miRNA-223. Podocytes were divided into the following nine groups: control group (no special treatment), empty plasmid group (transfected with empty plasmid), HBx overexpression group (transfected with HBx overexpression lentivirus), HBx overexpression+miRNA-223 mimic group (transfected with HBx overexpression lentivirus and miRNA-223 mimic), HBx overexpression+miRNA-223 inhibitor group (transfected with HBx overexpression lentivirus and miRNA-223 inhibitor), HBx overexpression+miRNA-223 mimic+NLRP3 group (transfected with HBx overexpression lentivirus, miRNA-223 mimic and NLRP3 overexpression plasmid), HBx overexpression+miRNA-223 mimic+ NLRP3 siRNA group (transfected with HBx overexpression lentivirus, miRNA-223 mimic and NLRP3 siRNA), HBx overexpression+miRNA-223 inhibitor+NLRP3 group (transfected with HBx overexpression lentivirus, miRNA-223 inhibitor and NLRP3 overexpression plasmid), HBx overexpression+miRNA-223 inhibitor+NLRP3 siRNA group (transfected with HBx overexpression lentivirus, miRNA-223 inhibitor and NLRP3 siRNA).Results:miRNA-223 was down-regulated in HBx overexpression group compared with the control group ( P < 0.05). TUNEL and immunofluorescence staining showed that NLRP3 knockdown attenuated podocyte injury and pyroptosis induced by HBx overexpression ( P < 0.05). Dual luciferase reporter gene assay demonstrated that NLRP3 was one of the downstream targets of miRNA-223. Rescue experiments revealed that NLRP3 overexpression weakened the protective effect of miRNA-223 in podocyte injury ( P < 0.05). The addition of miRNA-223 mimic and NLRP3 siRNA decreased the expression of NLRP3 inflammasome and cytokines, and reduced the number of pyroptosis cells induced by HBx overexpression (all P < 0.05); The addition of miRNA-223 inhibitor and NLRP3 overexpression plasmid significantly increased the expression of NLRP3 inflammasome and cytokines, caspase-1 activity, and the number of pyroptosis cells (all P < 0.05). Conclusion:HBx may promote podocyte pyroptosis of HBV-GN via downregulating miRNA-223 targeting NLRP3 inflammasome, suggesting that miRNA-223 is expected to be a potential target for the treatment of HBV-GN.

BACKGROUND@#Ovarian cancer is one of the most widespread malignant diseases of the female reproductive system worldwide. The plurality of ovarian cancer is diagnosed with metastasis in the abdominal cavity. Epithelial-mesenchymal transition (EMT) exerts a vital role in tumor cell metastasis. However, it remains unclear whether long non-coding RNA (lncRNA) are implicated in EMT and influence ovarian cancer cell invasion and metastasis. This study was designed to investigate the impacts of lncRNA AC005224.4 on ovarian cancer.@*METHODS@#LncRNA AC005224.4, miR-140-3p, and snail family transcriptional repressor 2 ( SNAI2 ) expression levels in ovarian cancer and normal ovarian tissues were determined using real-time quantitative polymerase chain reaction (qRT-PCR). Cell Counting Kit-8 (CCK-8) and Transwell (migration and invasion) assays were conducted to measure SKOV3 and CAOV-3 cell proliferation and metastasis. E-cadherin, N-cadherin, Snail, and Vimentin contents were detected using Western blot. Nude mouse xenograft assay was utilized to validate AC005224.4 effects in vivo . Dual-luciferase reporter gene assay confirmed the targeted relationship between miR-140-3p and AC005224.4 or SNAI2 .@*RESULTS@#AC005224.4 and SNAI2 upregulation and miR-140-3p downregulation were observed in ovarian cancer tissues and cells. Silencing of AC005224.4 observably moderated SKOV3 and CAOV-3 cell proliferation, migration, invasion, and EMT process in vitro and impaired the tumorigenesis in vivo . miR-140-3p was a target of AC005224.4 and its reduced expression level was mediated by AC005224.4. miR-140-3p mimics decreased the proliferation, migration, and invasion of ovarian cancer cells. SNAI2 was identified as a novel target of miR-140-3p and its expression level was promoted by either AC005224.4 overexpression or miR-140-3p knockdown. Overexpression of SNAI2 also facilitated ovarian cancer cell viability and metastasis.@*CONCLUSION@#AC005224.4 was confirmed as an oncogene via sponging miR-140-3p and promoted SNAI2 expression, contributing to better understanding of ovarian cancer pathogenesis and shedding light on exploiting the novel lncRNA-directed therapy against ovarian cancer.

Objective To investigate the epidemic situation of measles in Yichang from 2009 to 2021, and to provide scientific evidence for the control and elimination of measles. Methods Descriptive epidemiological methods were used to analyze the case data of measles cases reported by the notifiable infectious disease reporting system and measles surveillance system in Yichang from 2009 to 2021. Results A total of 364 cases of confirmed measles were reported in Yichang from 2009 to 2021, with an average annual incidence rate of 0.68/100 000. During these years, the incidence rates fluctuated from 0.5 to 28.87/100 000. The epidemic peak of measles was from January to July. Most cases were concentrated in five regions including Xiling, Wujiagang, Yiling, Dangyang and Yidu, accounting for 66.48% of all cases. More male cases were reported. The age of these patients ranged from < 1 month to 68 years, in which a great majority were infants (32.14%) and adults between 20 and 49 years old (48.08%). The five most common occupations of measles patients were scattered children, farmers, housekeeping or unemployed, workers and students, with the scattered children being the highest proportion accounting for 42.58%. There were 72 cases (19.78%) with the history of measles vaccine immunization, 113 cases (31.04%) without the immunization history, and 179 cases (49.18%) with unknown immunization history. Conclusion Incidence rates of measles in Yichang remains at a low level from 2009 to 2021. Young age groups and adults are the key groups for measles prevention and control. Strategies and measures such as immune strengthening for key areas and key populations will help improve the effect of measles prevention and control.

Two evaluators independently screened and extracted the obtained literature according to the inclusion and exclusion criteria, and used the Newcastle-Ottawa Scale for quality evaluation. Meta-analysis was conducted by RevMan 5.3 software and Stata SE/MP(14.0 version).Results:A total of 13 studies were included, including 23 related risk factors. Among them, prolonged use of catheters, palliative treatment, hematological tumors, neutropenia, hospitalized patients, and chemotherapy were risk factors for implantable venous access port-related bloodstream infections in tumor patients, with statistically significant differences ( OR values ranging from 0.26 to 8.77, all P<0.05). Conclusions:The long time of catheter use, palliative treatment, hematological tumor, neutropenia and chemotherapy were the risk factors of implantable venous access port-related bloodstream infection in patients with tumor, Medical personnel should make a good assessment and strengthen health education to minimize the chances of infection and effectively reduce the incidence of infection related to the infusion port.
RESUMEN
Cancer-associated fibroblasts (CAFs) is considered as a key factor for the severely limited efficacy in tumor radiotherapy. CAFs, as the primary stromal cells in the tumor microenvironment, can lead to tumor radiotherapy resistance by secreting a series of pro-tumor cytokines and nutrients, inhibiting anti-tumor immune response and remodeling extracellular matrix. Some progress has been made in the study of targeted CAFs sensitization radiotherapy, but the relevant study system is still imperfect. Therefore, a systematic exploration of the role of CAFs in tumor radiotherapy resistance and CAFs targeted therapy strategies can provide a basis for improving the current status of tumor radiotherapy resistance.
RESUMEN
Gastroesophageal reflux disease (GERD) is one of the most common digestive diseases with high incidence, complicated clinical symptoms, difficulties in standard treatment, and heavy medical burden. At present, some GERD-relevant clinical practice guidelines (CPGs) have been issued by different countries and academic organizations, but some recommendations were inconsistent, which has caused some problems for the current clinical whole-course management of GERD. To summarize the relevant evidence among the CPGs on GERD and formulate the whole- course management strategies, we included GERD-relevant CPGs published or updated after 2010 by searching websites of guidelines, relevant professional societies, and electronic databases. We extracted the recommendations and summarized the evidence from the aspects of symptoms, epidemiology, diagnosis and treatment, which was presented in the form of evidence mapping. We included 24 CPGs, including three in Chinese and 21 in English. The clinical practice management strategies of GERD were formulated based on the evidence from the aspects of clinical symptoms, diagnostic methods, medical treatment, anti-reflux surgery and endoscopic treatment, psychological treatment, and traditional Chinese medicine treatment.

BackgroundGender and age differences in the clinical manifestations of patients with bipolar disorder can affect the clinical diagnosis and treatment process. The current treatment effect of bipolar disorder in adolescents is not ideal， which has become the main reason for disability during the learning period. ObjectiveTo analyze the clinical features and medication therapy status of bipolar disorder in adolescents， and to provide references to support for personalized diagnosis and treatment. MethodsOn January 16， 2023， 1 169 patients with bipolar disorder who were hospitalized at Beijing Anding Hospital Affiliated Capital Medical University from January 1， 2014 to December 31， 2017 were retrospectively enrolled. Medical records were collected and analyzed to compare the clinical features among patients of different gender and age groups， and to explore the differences in medication use among patients of different genders in different types of seizures. ResultsMale patients reported a larger proportion of manic episodes， and a smaller proportion of depressive episodes than female patients （P<0.05）.Female patients reported a larger proportion of non-suicidal self-harm behaviors than male patients （χ2=7.761， P<0.01）.And patients in low-age group featured a larger proportion of mixed seizures， impulsive behaviors and family history of bipolar disorders along with a smaller proportion of manic episodes than those in high-age group （P<0.05 or 0.01）. High-age group had a longer average length of hospital stay than low-age group （t=-2.930， P<0.01）. In manic episode patients， males were found to have a larger proportion of valproate and atypical antipsychotic drug administration than females （P<0.01）. Among atypical antipsychotic drugs， males accounted for a larger proportion of administration of risperidone and olanzapine （χ2=26.957） than females （P<0.05 or 0.01）， while females constituted a larger proportion of administration of quetiapine （χ2=14.865） and aripiprazole than males （P<0.01）. In depressive episode patients， females had a larger proportion of administration of olanzapine than males （P<0.01）. In patients with mixed seizures， females occupied a larger proportion of administration of lithium carbonate than males （χ2=9.253， P<0.01）， and males exhibited a larger proportion of administration of valproate than females （P<0.05）. ConclusionDifferences have been shown in diagnostic classification and concomitant symptoms among adolescent bipolar disorder of different genders and ages. Furthermore， medications of lithium carbonate， valproate， atypical antipsychotic and other drugs differ by gender among adolescents of different subtypes of bipolar disorder. ［Funded by Key Special Project of the National Key R&D Program of the Ministry of Science and Technology for "Major Chronic Non communicable Disease Prevention and Control Research" （number， 2017YFC1311101）］
