Objective To observe the value of gastric filling ultrasound(GFUS)for diagnosing dysphagia after surgical operation of hiatal hernia(HH).Methods Totally 71 HH patients who underwent laparoscopic HH repair and fundoplication surgery were retrospectively enrolled and divided into dysphagia group(n=23)and non dysphagia group(n=48)according to postoperative Saeed scores.GFUS parameters,including inner diameter of esophageal hiatus lumen(IDE),wall thickness of abdominal esophageal(WTE)and inner diameter of the esophageal lumen at the fold(FIDE)were compared between groups,and their value of diagnosing postoperative dysphagia were analyzed.Results In dysphagia group,IDE and FIDE were lower,while WTE was higher than those in non dysphagia group(all P＜0.05).Low IDE and high WTE were both independent risk factors of postoperative dysphagia in HH patients.The sensitivity,specificity and area under the curve(AUC)of IDE for diagnosing dysphagia after surgical operation of HH was 82.64％,66.69％and 0.773,of WTE was 82.59％,68.73％and 0.793,of their combination was 88.89％,77.59％and 0.843,respectively.The AUC of the combination of IDE and WTE was higher than that of IDE and WTE alone(Z=1.328,1.364,P=0.044,0.043).Conclusion Combination of GFUS parameters IDE and WTE was valuable for diagnosing dysphagia after surgical operation of HH.

The clinical practice guidelines of traditional Chinese medicine （TCM） have problems such as limited clinical application and unclear implementation effects， which may be related to the lack of clinical practice evidence. To provide reliable and precise evidence for clinical practice， this article proposes a model of combining TCM guidelines with real-world study， which includes 4 steps. Firstly， during the implementation process of the guidelines， a high-quality research database is established. Secondly， the recommendations in the guidelines are evaluated based on the established database in multiple dimensions， including applicability， effectiveness， safety， and cost-effectiveness， and thus their effectiveness in practical applications can be determined. Thirdly， based on the established database， core prescriptions are identified， and the targeted populations and medication plans are determined. That is， the best treatment regimen is established based on the analysis of abundant clinical data regarding the effects of different medication frequencies， dosages， and duration on efficacy. Fourthly， the guidelines are updated according to the real-world evidence. The research based on this model can provide real-world evidence for ancient and empirical prescriptions， improving their application in clinical practice. Moreover， this model can reduce research costs and improve research efficiency. When applying this model， researchers need to pay attention to the quality of real-world evidence， ensuring that it can truly reflect the situation in clinical practice. In addition， importance should be attached to the clinical application of guideline recommendations， ensuring that doctors can conduct standardized diagnosis and treatment according to the guidelines. Finally， full-process participation of multidisciplinary experts is encouraged to ensure the comprehensiveness and scientificity of the study. In conclusion， the application of this model will contribute to the development of TCM guidelines responsive to the needs of clinical practice and achieve the goal of promoting the homogenization of TCM clinical diagnosis and treatment.

As a supplement to randomized controlled trials， observational studies can provide evidence for the effectiveness of traditional Chinese medicine （TCM） treatment measures. They can also study influencing factors of diseases， etiology， and prognosis. However， there is a confounding effect due to the lack of randomization， which seriously affects the causal inference between the study factors and the outcome， resulting in confounding bias. Therefore， identifying and controlling confounding factors are key issues to be addressed in TCM observational studies. According to the causal network and the characteristics of TCM theory， confounding factors can be categorized into measured and unmeasured confounding factors. In addition， attention must be paid to identifying confounding factors and intermediate variables， as well as the interaction between confounding factors and study factors. For methods of controlling confounding factors， measured confounding factors can be controlled by stratification， multifactor analysis， propensity scores， and disease risk scores. Unmeasured and unknown confounding factors can be corrected using instrumental variable methods， difference-in-difference methods， and correction for underlying event rate ratios. Correcting and controlling confounding factors can ensure a balance between groups， and confounding bias can be reduced. In addition， methods such as sensitivity analysis and determination of interactions make the control of confounding factors more comprehensive. Due to the unique characteristics of TCM， observational studies of TCM face unique challenges in identifying and controlling confounding factors， including the ever-changing TCM treatment measures received by patients， the often-overlooked confounding effects in the four diagnostic information of TCM， and the lack of objective criteria for TCM evidence-based diagnosis. Some scholars have already conducted innovative explorations to address these issues， providing a methodological basis for conducting higher-quality TCM observational studies， so as to obtain more rigorous real-world evidence of TCM and gradually develop quality evaluation criteria for OS that are consistent with the characteristics of TCM.

The classification of traditional Chinese medicine （TCM） syndromes is one of the core technical elements in the industry standard of Specification of Diagnosis and Therapeutic Effect Evaluation of Diseases and Syndromes in TCM. In the past，when clinical standards for TCM were formulated，the determination of TCM syndrome classification relied heavily on textbooks and expert experience，lacking systematic research. This approach thus failed to reflect the advancement and scientificity of the standards，thereby affecting their implementation and application. This article reviewed the presentation forms and technical methods of TCM syndrome classification，including the two-tier syndrome classification model with primary and secondary symptoms，as well as the application of modern literature research，ancient literature research，Delphi method，in-depth expert interviews，consensus conferences，and real-world research. When syndrome classification standards are developed，it is necessary to build upon modern literature research，adopt a mixed approach combining qualitative research and quantitative analysis results，and reach expert consensus through consensus conferences. Through systematic research，the scientificity，applicability，and coordination of TCM syndrome classification standards can be enhanced，providing guidance for the standardization of TCM.

Objective To understand the epidemiological characteristics of Chlamydia trachomatis infection in Hubei province, and to provide scientific basis for prevention and control. Methods The data of Chlamydia trachomatis infection cases reported through the China Information System for Disease Control and Prevention from 2008 to 2022 were collected for epidemiological statistical analysis. Results The incidence of Chlamydia trachomatis infection in Hubei Province showed an increasing trend from 2008 to 2022, with an average annual reported incidence of 2.26/100 000. The top three reported incidence areas were Shiyan (6.04/100 000), Yichang (5.62/100 000) and Shennongjia (3.47/ 100 000). The reported incidence in southeast area was significantly higher than that in other areas (χ²=2869.603 , P < 0.001). The high incidence age group was 20-39 years old, accounting for more than 70%. The reported incidence in females was higher than that in males (χ²=1429.27 , P < 0.001). Housework and unemployment were the most common professions (43.54%). The case reporting institutions were mainly comprehensive hospitals (87.29%). Conclusion To effectively control the infection and transmission of Chlamydia trachomatis, it is necessary to strengthen the health popularization of STD knowledge, intervention and early active screening of high-risk groups.

Postoperative pain seriously affects the recovery process of patients, resulting in prolonged hospital stay and increased care costs. Appropriate application of patient-controlled analgesia devices can effectively relieve perioperative acute pain. In 1994 patient-controlled analgesia began to be used in Peking Union Medical College Hospital, and the Acute Pain Service Working Group was established in 2004. With the cooperation of anesthesiologists and specialist nurses, the group jointly has implemented the whole process and standardized management based on patient-controlled analgesia, and constantly improved and innovated working methods, laying a solid foundation for the development of postoperative pain management. This paper systematically reviews and summarizes the work from the aspects of clinical focus, nursing management experience, promotion and dissemination of pain treatment concepts, and development of acute pain service model under the new situation, with the hope of providing valuable reference for comprehensively strengthening pain management in the process of diagnosis and treatment, and enhancing patients' satisfaction with perioperative analgesia services.

OBJECTIVE To investigate the role of the complement C3/C3aR signaling pathway in the prefrontal cortex and colon neuroglia cell interactions during meth-amphetamine(METH)addiction,to observe the effects of TLR4 inhibitors as well as complement C3 elimination on METH reward and relapse behavior,and to explore the neuroinflammatory mechanisms of complement C3 acti-vation in METH addiction.METHODS ①A 14 d and 28 d rat METH addiction model was established to observe the effects of TLR4 antagonist ibudilast 3 mg·kg-1 and 10 mg·kg-1 on self-administration,reward motivation,relapse,and natural reward behavior in METH-trained 14 d rats and the effects of 0.02 mg·kg-1 complement C3 antago-nist on self-administration behavior in METH-trained 28 d rats.② Differences in the expression of TLR4,NF-κB,GRP94,C3,cathepsin L,CD68,and GFAP in the pre-frontal cortex of each group were examined using West-ern blotting.③ In addition,the expression of ATF6 in the prefrontal cortex of each group and the effects on neuro-nal and microglia/macrophage INOS,CD206 GRP94,and complement C3/C3aR.RESULTS ① Endoplasmic reticulum stress occurred in neurons and microglia after METH exposure depending on GRP94 and unfolded pro-tein responses to the ATF6 pathway.In addition,it acti-vates the TLR4-NF-κB pathway.② Microglia with high complement C3/C3aR expression in the prefrontal cortex were recruited to synaptic pruning and phagocytic responses around neurons with high GRP94,comple-ment C3/C3aR expression and these effects were blocked by complement C3 antagonists.③ In the rec-tum,GRP94 functions as a molecular chaperone for com-plement C3 and cathepsin L.Crosstalk occurs between enteric neurons high in GRP94,complement C3,and macrophages high in C3aR,located in the submucosa,lamina propria,and muscular,respectively,and all of these effects are blocked by complement C3 antago-nists.④ Treatment with the TLR4 antagonist ibudilast inhibits self-administration,reward motivation,and cue-or METH-priming in METH-trained 14 d rats,but fails to affect natural reward behavior.Ibudilast treatment attenu-ates the TLR4-NF-κB inflammatory pathway and comple-ments C3/C3aR pathway in the prefrontal cortex.CON-CLUSION Activation of the complement C3/C3aR signal-ing pathway by TLR4-NF-κB inflammatory signaling in the prefrontal cortex mediates the METH addiction pro-cess,providing an experimental basis for the clinical treatment of METH addiction,and targeting TLR4/NF-κB inflammatory signaling and complement C3/C3aR may be a new way to intervene in METH addiction.
