Based on clinical epidemiological data， it is believed that qi deficiency constitution is closely related to allergic diseases. According to the fundamental principles of traditional Chinese medicine （TCM） constitution theory， the intrinsic connection between qi deficiency constitution and allergic diseases is analyzed from the perspectives of inherited endowment， life process， environmental restriction， and the interplay of form and spirit. This paper discusses the key points of regulating qi deficiency constitution to prevent allergic diseases in three stages， prevention before illness， prevention of disease progression， and prevention of recurrence after recovery. It also distinguishes the treatment directions for regulating qi deficiency constitution to treat allergic diseases based on different disease locations such as the lung， spleen， and kidney. This aims to expand new ideas for the research on qi deficiency constitution and allergic diseases as well as the prevention and treatment of allergic diseases.

ObjectiveRepetitive transcranial magnetic stimulation (rTMS) has demonstrated efficacy in enhancing neurocognitive performance in Alzheimer’s disease (AD), but the neurobiological mechanisms linking synaptic pathology, neural oscillatory dynamics, and brain network reorganization remain unclear. This investigation seeks to systematically evaluate the therapeutic potential of rTMS as a non-invasive neuromodulatory intervention through a multimodal framework integrating clinical assessments, molecular profiling, and neurophysiological monitoring. MethodsIn this prospective double-blind trial, 12 AD patients underwent a 14-day protocol of 20 Hz rTMS, with comprehensive multimodal assessments performed pre- and post-intervention. Cognitive functioning was quantified using the mini-mental state examination (MMSE) and Montreal cognitive assessment (MOCA), while daily living capacities and neuropsychiatric profiles were respectively evaluated through the activities of daily living (ADL) scale and combined neuropsychiatric inventory (NPI)-Hamilton depression rating scale (HAMD). Peripheral blood biomarkers, specifically Aβ1-40 and phosphorylated tau (p-tau181), were analyzed to investigate the effects of rTMS on molecular metabolism. Spectral power analysis was employed to investigate rTMS-induced modulations of neural rhythms in AD patients, while brain network analyses incorporating topological properties were conducted to examine stimulus-driven network reorganization. Furthermore, systematic assessment of correlations between cognitive scale scores, blood biomarkers, and network characteristics was performed to elucidate cross-modal therapeutic associations. ResultsClinically, MMSE and MOCA scores improved significantly (P<0.05). Biomarker showed that Aβ1-40 level increased (P<0.05), contrasting with p-tau181 reduction. Moreover, the levels of Aβ1-40 were positively correlated with MMSE and MOCA scores. Post-intervention analyses revealed significant modulations in oscillatory power, characterized by pronounced reductions in delta (P<0.05) and theta bands (P<0.05), while concurrent enhancements were observed in alpha, beta, and gamma band activities (all P<0.05). Network analysis revealed frequency-specific reorganization: clustering coefficients were significantly decreased in delta, theta, and alpha bands (P<0.05), while global efficiency improvement was exclusively detected in the delta band (P<0.05). The alpha band demonstrated concurrent increases in average nodal degree (P<0.05) and characteristic path length reduction (P<0.05). Further research findings indicate that the changes in the clinical scale HAMD scores before and after rTMS stimulation are negatively correlated with the changes in the blood biomarkers Aβ1-40 and p-tau181. Additionally, the changes in the clinical scales MMSE and MoCA scores were negatively correlated with the changes in the node degree of the alpha frequency band and negatively correlated with the clustering coefficient of the delta frequency band. However, the changes in MMSE scores are positively correlated with the changes in global efficiency of both the delta and alpha frequency bands. Conclusion20 Hz rTMS targeting dorsolateral prefrontal cortex (DLPFC) significantly improves cognitive function and enhances the metabolic clearance of β-amyloid and tau proteins in AD patients. This neurotherapeutic effect is mechanistically associated with rTMS-mediated frequency-selective neuromodulation, which enhances the connectivity of oscillatory networks through improved neuronal synchronization and optimized topological organization of functional brain networks. These findings not only support the efficacy of rTMS as an adjunctive therapy for AD but also underscore the importance of employing multiple assessment methods—including clinical scales, blood biomarkers, and EEG——in understanding and monitoring the progression of AD. This research provides a significant theoretical foundation and empirical evidence for further exploration of rTMS applications in AD treatment.

The transcription factor HOXB13 plays crucial roles in cancer development. HOXB13 is abnormally expressed in most cancers, which makes it a valuable therapeutic target for cancer therapy. The level of HOXB13 differs significantly between healthy and cancer tissues, which indicates that the level of HOXB13 is closely related to carcinogenesis. The regulatory network mediated by HOXB13 in cancer proliferation, metastasis, and invasion has been systematically investigated. Moreover, HOXB13 variants play distinct roles in different cancers and populations. By understanding the molecular mechanisms and mutation features of HOXB13, we provide a comprehensive overview of carcinogenesis networks dependent on HOXB13. Finally, we discuss advancements in anticancer therapy targeting HOXB13 and the roles of HOXB13 in drug resistance to molecular-targeted therapies, which serves as a foundation for developing HOXB13-targeted drugs for clinical diagnosis and cancer therapies.

ObjectiveTo investigate the features of liver histopathological damage in patients with indeterminate phase of chronic HBV infection， as well as the timing for initiating antiviral therapy in such patients. MethodsA retrospective screening was performed for the patients with chronic HBV infection who were hospitalized in The Fifth Medical Center of Chinese PLA General Hospital and underwent liver biopsy from March 2018 to April 2022， among whom the patients who met the criteria for indeterminate phase defined in Chinese guidelines for chronic hepatitis B prevention and treatment （2022 edition） were enrolled， and their clinical data were collected. Liver histopathological stage was determined using the Scheuer scoring system， with stages 0 — 4 for inflammation grade （G） and stages 0 — 4 for fibrosis degree （S）， and the patients were divided into groups based on the presence of significant necroinflammation （≥G2） and significant liver fibrosis （≥S2）. The independent samples t-test was used for comparison of normally distributed continuous data between two groups， and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups； the chi-square test or the Fisher’s exact test was used for comparison of categorical data between two groups. A Spearman’s rank correlation analysis was used to investigate the correlation between liver histopathology and clinical factors， and the Logistic regression model was used to identify the independent influencing factors for significant necroinflammation and liver fibrosis. ResultsA total of 271 patients with indeterminate phase of chronic HBV infection were enrolled， among whom 61 （22.5%） had significant necroinflammation （≥G2） and 124 （45.8%） had significant liver fibrosis （≥S2）. The Logistic regression analysis showed that alanine aminotransferase ≥30 U/L （for male patients） or ≥19 U/L （for female patients） （odds ratio ［OR］=2.69， 95% confidence interval ［CI］： 1.39 — 5.21， P=0.003）， HBV DNA ≥2 000 IU/mL （OR=2.75， 95%CI： 1.38 — 5.48， P=0.004）， and liver stiffness measurement （LSM） ≥6.0 kPa （OR=4.57， 95%CI： 2.17 — 9.62， P<0.001） were independent risk factors for significant inflammation. HBV DNA ≥2 000 IU/mL （OR=1.82， 95%CI： 1.01 — 3.32， P=0.049） and LSM ≥6.0 kPa （OR=2.06， 95%CI： 1.23 — 3.43， P=0.006） were independent influencing factors for significant liver fibrosis. ConclusionAmong the patients with indeterminate phase of chronic HBV infection， a substantial proportion of patients have significant liver histopathological damage. Antiviral therapy should be initiated in a timely manner for patients with high-risk factors.

Objective:To investigate the improvement effect of the freeze-dried garlic powder on acute myocardial ischemia and its effect on phosphatidylinositol 3 kinase/protein kinase B/nuclear factor erythroid 2-related factor 2 (PI3K/Akt/Nrf2) signaling pathway.Methods:SD rats were randomly divided into sham-operation group, model group, positive drug group, and garlic freeze-dried powder low-, medium-, and high-dosage groups using a random number table method, with 12 rats in each group. The garlic freeze-dried powder low-, medium-, and high-dosage groups were orally administered with 0.58, 1.16, and 2.32 g/kg of garlic freeze-dried powder solution, the positive reference drug group was orally administered with 0.26 g/kg of compound Danshen tablet solution, and the model group and sham-operation group were orally administered with equal volumes of distilled water once a day for 14 consecutive days. Except for the sham-operation group, all other groups were prepared with acute myocardial ischemia models in rats by ligating the left anterior descending coronary artery. Electrocardiogram testing was performed. The incidence of ventricular premature beats, ventricular tachycardia, and ventricular fibrillation in each group was counted. Myocardial infarction was observed through TTC staining, and the myocardial infarction rate was calculated; serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), LDH, cardiac troponin T (cTnT), total antioxidant capacity (T-AOC), SOD, MDA, IL-1β, TNF-α levels were detected, and Western blot was used to detect myocardial tissue p-PI3K, p-Akt, Nrf2, HO-1 and Keap1 proteins.Results:Compared with the model group, the incidence of premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation in rats in each treatment group was reduced. Compared with the model group, the positive drug group and garlic freeze-dried powder medium- and high-dosage groups showed a decrease in myocardial infarction rate in rats ( P<0.05); compared with the model group, the levels of serum T-AOC and SOD in each treatment group increased ( P<0.05 or P<0.01), while the level of MDA decreased ( P<0.05 or P<0.01); the levels of CK, LDH, cTnT, IL-1β, and TNF-α in the serum of rats in the positive drug group and garlic freeze-dried powder high-dosage group decreased ( P<0.05 or P<0.01), while the expressions of p-PI3K, p-Akt, Nrf2, and HO-1 proteins in myocardial tissue increased ( P<0.05 or P<0.01), and the expression of Keap1 protein decreased ( P<0.05 or P<0.01). Conclusions:Garlic freeze-dried powder can improve acute myocardial ischemia of rats by reducing the release of serum myocardial enzymes and exerting antioxidant and anti-inflammatory effects. The mechanism may be related to regulating PI3K/Akt/Nrf2 signaling pathway.

Objective To analyze the epidemiological patterns and pathogens of clusters of diarrhea in Xicheng Distract , Beijing during 2017-2022 , in order to update the policy of prevention. Mehods Between January 2017 and December 2022, stool samples of patients and partly cooks in clusters of diarrhea were collected and tested by Real-time PCR for Rotavirus, Norovirus, Adenovirus, Sapovirus and Astrovirus. Part of ORF1/ORF2 from Norovirus positive samples were amplified using RT-PCR. PCR products were sequenced and the genetypes were determined. Results Four hundreds and one clusters of diarrheas were reported. Among them , 369 were reported in kindergartens, primary schools and secondary schools. The morbidities were 4.14, 2.13 and 0.69 per thousand, respectively. Seventy four cooks in 15 clusters of diarrhea were Norovirus positive. The rate was 8.67%. Among these pathogens, Norovirus had the largest proportion , but the trend was declining. At least three kinds of genetype of GⅡ Norovirus were detected every year. Conclusion Clusters of diarrhea mainly occurred in kindergartens, primary schools and secondary schools. Result from the increasing proportions of unknown-cause clusters of diarrhea, the testing methods and scopes of pathogens should be extended. Diverse genetypes of Norovirus coexist and alternate in Beijing. So appearance of new genetypes and recombination of existed ones of Norovirus should be closely concerned.

With the increasing proportion of human papilloma virus(HPV)infection in the pathogenic factors of oro-pharyngeal cancer,a series of changes have occurred in the surgical treatment.While the treatment mode has been im-proved,there are still many problems,including the inconsistency between diagnosis and treatment modes,the lack of popularization of reconstruction technology,the imperfect post-treatment rehabilitation system,and the lack of effective preventive measures.Especially in terms of treatment mode for early oropharyngeal cancer,there is no unified conclu-sion whether it is surgery alone or radiotherapy alone,and whether robotic minimally invasive surgery has better func-tional protection than radiotherapy.For advanced oropharyngeal cancer,there is greater controversy over the treatment mode.It is still unclear whether to adopt a non-surgical treatment mode of synchronous chemoradiotherapy or induction chemotherapy combined with synchronous chemoradiotherapy,or a treatment mode of surgery combined with postopera-tive chemoradiotherapy.In order to standardize the surgical treatment of oropharyngeal cancer in China and clarify the indications for surgical treatment of oropharyngeal cancer,this expert consensus,based on the characteristics and treat-ment status of oropharyngeal cancer in China and combined with the international latest theories and practices,forms consensus opinions in multiple aspects of preoperative evaluation,surgical indication determination,primary tumor re-section,neck lymph node dissection,postoperative defect repair,postoperative complication management prognosis and follow-up of oropharyngeal cancer patients.The key points include:① Before the treatment of oropharyngeal cancer,the expression of P16 protein should be detected to clarify HPV status;② Perform enhanced magnetic resonance imaging of the maxillofacial region before surgery to evaluate the invasion of oropharyngeal cancer and guide precise surgical resec-tion of oropharyngeal cancer.Evaluating mouth opening and airway status is crucial for surgical approach decisions and postoperative risk prediction;③ For oropharyngeal cancer patients who have to undergo major surgery and cannot eat for one to two months,it is recommended to undergo percutaneous endoscopic gastrostomy before surgery to effectively improve their nutritional intake during treatment;④ Early-stage oropharyngeal cancer patients may opt for either sur-gery alone or radiation therapy alone.For intermediate and advanced stages,HPV-related oropharyngeal cancer general-ly prioritizes radiation therapy,with concurrent chemotherapy considered based on tumor staging.Surgical treatment is recommended as the first choice for HPV unrelated oropharyngeal squamous cell carcinoma(including primary and re-current)and recurrent HPV related oropharyngeal squamous cell carcinoma after radiotherapy and chemotherapy;⑤ For primary exogenous T1-2 oropharyngeal cancer,direct surgery through the oral approach or da Vinci robotic sur-gery is preferred.For T3-4 patients with advanced oropharyngeal cancer,it is recommended to use temporary mandibu-lectomy approach and lateral pharyngotomy approach for surgery as appropriate;⑥ For cT1-2N0 oropharyngeal cancer patients with tumor invasion depth＞3 mm and cT3-4N0 HPV unrelated oropharyngeal cancer patients,selective neck dissection of levels ⅠB to Ⅳ is recommended.For cN+HPV unrelated oropharyngeal cancer patients,therapeutic neck dissection in regions Ⅰ-Ⅴ is advised;⑦ If PET-CT scan at 12 or more weeks after completion of radiation shows intense FDG uptake in any node,or imaging suggests continuous enlargement of lymph nodes,the patient should undergo neck dissection;⑧ For patients with suspected extracapsular invasion preoperatively,lymph node dissection should include removal of surrounding muscle and adipose connective tissue;⑨ The reconstruction of oropharyngeal cancer defects should follow the principle of reconstruction steps,with priority given to adjacent flaps,followed by distal pedicled flaps,and finally free flaps.The anterolateral thigh flap with abundant tissue can be used as the preferred flap for large-scale postoperative defects.

Objective To evaluate the analgesia effect of nalbuphine combined with transversus abdominis plane block(TAPB)multimodal analgesia on patients after radical resection of liver cancer,and to observe its safety.Methods The clinical data of patients who underwent radical resection of liver cancer were retrospectively collected.According to different postoperative anesthesia regimens,they were divided into control group and treatment group by the cohort method.The control group was treated with TAPB combined with 2 μg·kg-1 sufentanil+ondansetron 16 mg for patient-controlled intravenous analgesia(PCIA),while the treatment group was given TAPB combined with 2 mg·kg-1 nalbuphine+ondansetron 16 mg for PCIA.The perioperative anesthetic dosage,heart rate(HR),anesthesia effect,postoperative visual analogue scale(VAS)and Bruggman comfort score(BCS)were compared,and the total number of analgesia pump compressions,the number of effective compressions,remedial analgesia rate,postoperative ambulation time,postoperative exhaust time and occurrence of drug-related adverse reactions were recorded in the two groups.Results 57 cases in control group and 53 cases in treatment group were included for analysis.The HR values at 5 min after tracheal extubation in treatment group and control group were(66.38±7.65)and(70.74±8.12)beat·min-1,VAS scores at 48 h after surgery were(1.14±0.36)and(1.75±0.69)points,BCS scores were(2.51±0.45)and(2.30±0.55)points,the total number of analgesia pump compressions after PCIA were(6.89±1.75)and(12.61±2.39)times,the number of effective compressions were(3.64±0.91)and(8.27±1.15)times,the remedial analgesia rates were 5.66％(3 cases/53 cases)and 19.30％(11 cases/57 cases),the incidence rates of nausea and vomiting were 5.66％(3 cases/53 cases)and 19.30％(11 cases/57 cases),respectively(all P＜0.05).The overall excellent and good rates of anesthesia in treatment group and control group were 96.23％(51 cases/53 cases)and 89.47％(51 cases/57 cases),the total incidence rates of adverse drug reactions were 11.32％(6 cases/53 cases)and 22.81％(13 cases/57 cases),respectively(all P＞0.05).Conclusion Nalbuphine combined with TAPB multimodal analgesia has good analgesia effect after radical resection of liver cancer,and it is beneficial to reducing the occurrence of postoperative nausea and vomiting,and it is safe and effective.

Objective To explore the influence of intravenous injection of cis-atracurium during anesthesia induction on QT interval(QTc),hemodynamics and oxidative stress level in patients undergoing hysteroscopic surgery.Methods Patients undergoing hysteroscopic surgery were classified into control group and treatment group.The treatment group was given intravenous injection of 2 mg·kg-1 of propofol emulsion injection+3 μg·kg-1 of fentanyl+0.15 mg·kg-1 of cis-atracurium besylate for injection,while the control group was given intravenous injection of 2 mg·kg-1 of propofol emulsion injection+3 μg·kg-1 of fentanyl+the same amount of 0.9％NaCl as treatment group.Laryngeal mask was placed in the two groups after 3 min,and laryngeal mask ventilation was given for general anesthesia.QTc value and hemodynamics[mean arterial pressure(MAP)]were detected before entering the room(T0),after 1 min of propofol+fentanyl intravenous injection(T1),after 1 min of cis-atracurium besylate for injection/0.9％NaCl(T2),immediately after laryngeal mask insertion(T3)and after 3 min of laryngeal mask insertion(T4).The anesthetic effect,postoperative dynamic pain visual analogue scale(VAS)score and sore throat were counted.The levels of serum oxidative stress indicators[superoxide dismutase(SOD),malondialdehyde(MDA)]at T0 and at the end of surgery(T5)were detected,and the safety was assessed.Results Fifty-two cases in treatment group and forty-four cases in control group were included.There was no statistical difference in QTc value between treatment group and control group at T0-T4(all P＞0.05).The MAP values in treatment group and control group at T3 were(84.22±5.96)and(86.78±6.11)mmHg,respectively,with a statistical difference(P＜0.05).The laryngeal mask insertion times in treatment group and control group were(17.02±2.47)and(19.52±2.34)s;the spontaneous breathing recovery times were(8.51±1.84)and(6.18±1.15)min;the eye opening time were(10.49±2.42)and(9.53±2.17)min;the laryngeal mask removal time were(11.16±2.16)and(10.21±2.34)min;the incidence rates of postoperative sore throat were 13.46％and 31.82％,and the differences were statistically significant(all P＜0.05).The levels of SOD in treatment group and control group at T5 were(36.63±4.17)and(33.26±4.86)nU·mL-1;the levels of MDA were(7.42±2.14)and(8.59±2.83)mmol·L-1(all P＜0.05).The adverse drug reactions in treatment group were mainly nausea and vomiting,respiratory depression and hypotension,and the adverse drug reactions in control group were mainly nausea and vomiting and respiratory depression.The incidence rates of adverse reactions in treatment group and control group were 13.46％and 11.36％,respectively(P＞0.05).Conclusion Cis-atracurium intravenous injection during anesthesia induction has no influence on QTc in patients undergoing hysteroscopic surgery,and has advantages in stabilizing intraoperative hemodynamics,reducing postoperative sore throat and improving serum oxidative stress indicators.
