This article systematically reviews the current research status as well as diagnosis and treatment strategies of traditional Chinese medicine （TCM） for gastroesophageal reflux disease （GERD）. Studies demonstrate that TCM， based on the "disease-syndrome combination" approach， exhibits multi-target advantages in alleviating symptoms of various GERD subtypes， promoting mucosal repair， regulating emotions， and facilitating the reduction of western medication. To address clinical challenges such as symptom overlap and limited therapeutic efficacy， strategies have been proposed including "treating different diseases with the same method" and integrated regulation based on viscera correlation. Future efforts should focus on elucidating the mechanisms of compound prescriptions， promoting TCM drug development under the "three-combination" evaluation framework that integrates TCM theory， human experience and clinical trial evidence， and optimizing integrated traditional and western medicine models to enhance GERD management.

Objective To introduce the causes of accidents and the diagnosis and treatment of two patients with radiation-induced skin injury admitted to our hospital in 2023, and to provide a reference for the clinical treatment of subsequent radiation-induced skin injury. Methods The clinical treatment process of two patients with acute skin injury caused by external radiation exposure were summarized and analyzed. Results The exposure history of the two patients was reconstructed, the flaw detection scenario was simulated, the biological dose and hand skin exposure dose were estimated, and the infrared thermal imaging device was used for dynamic monitoring. A comprehensive analysis was conducted based on clinical manifestations and other data. The diagnosis of “Xie” was excessive exposure combined with acute radiation-induced skin injury on both hands (Grade IV for the right hand palm, index finger, and middle finger and Grade II for the left hand little finger). The diagnosis of “Hao” was acute radiation-induced skin injury on both hands (Grade I). The two patients received different clinical treatment measures: “Xie” was treated with both local and systemic therapies, while “Hao” was mainly treated with systemic therapy. Conclusion After systematic and effective treatment, the radiation-induced skin injuries healed in both patients.

To explore the advantages of traditional Chinese medicine （TCM） and integrative TCM-Western medicine approaches in the treatment of diabetic microvascular complications （DMC）， refine key pathophysiological insights and treatment principles， and promote academic innovation and strategic research planning in the prevention and treatment of DMC. The 38th session of the Expert Salon on Diseases Responding Specifically to Traditional Chinese Medicine， hosted by the China Association of Chinese Medicine， was held in Beijing， 2024. Experts in TCM， Western medicine， and interdisciplinary fields convened to conduct a systematic discussion on the pathogenesis， diagnostic and treatment challenges， and mechanism research related to DMC， ultimately forming a consensus on key directions. Four major research recommendations were proposed. The first is addressing clinical bottlenecks in the prevention and control of DMC by optimizing TCM-based evidence evaluation systems. The second is refining TCM core pathogenesis across DMC stages and establishing corresponding "disease-pattern-time" framework. The third is innovating mechanism research strategies to facilitate a shift from holistic regulation to targeted intervention in TCM. The fourth is advancing interdisciplinary collaboration to enhance the role of TCM in new drug development， research prioritization， and guideline formulation. TCM and integrative approaches offer distinct advantages in managing DMC. With a focus on the diseases responding specifically to TCM， strengthening evidence-based support and mechanism interpretation and promoting the integration of clinical care and research innovation will provide strong momentum for the modernization of TCM and the advancement of national health strategies.

ObjectiveTo investigate the first-diagnosed reporting rate and annual changing trends of chronic obstructive pulmonary disease (COPD) among adult residents in Changzhou City from 2020 to 2024, and to provide a scientific basis for the prevention and control of COPD in this region. MethodsData on first-diagnosed cases of COPD from 2020 to 2024 were collected from the Changzhou Health Data Management Platform, along with resident population data stratified by age group and sex for the corresponding years. Stratified analyses were conducted by diagnosis year, sex, and age group to calculate crude first-diagnosed reporting rate and age-specific first-diagnosed reporting rate. The age-standardized first-diagnosed reporting rate (ASFDRR) was calculated using data from the Seventh National Population Census of China (2020) as the standard population. A logarithmic-linear model was employed to estimate the average annual percentage change (AAPC) in ASFDRR, along with its 95%CI and P-value. ResultsFrom 2020 to 2024, a total of 12 925 first-diagnosed COPD cases of adult residents were reported in Changzhou City. The overall crude first-diagnosed reporting rate increased from 37.91/100 000 in 2020 to 100.68/100 000 in 2024. The overall ASFDRR rose from 116.83/100 000 in 2020 to 274.59/100 000 in 2024, with an AAPC of 26.55% (95%CI: 5.98%‒51.11%). Among these,9 831 new cases were male, with the crude first-diagnosed reporting rate increasing from 57.07/100 000 to 159.29/100 000, and the ASFDRR increasing from 92.54/100 000 to 223.82 / 100 000, with an AAPC of 27.58% (95%CI: 6.21%‒53.26%). There were 3 094 new female cases, with the crude first-diagnosed reporting rate rising from 19.53/100 000 to 45.39/100 000, and the ASFDRR increasing from 26.01/100 000 to 55.33/100 000, with an AAPC of 22.90% (95%CI: 5.19%‒43.59%). Both crude and age-standardized first-diagnosed reporting rates of COPD for the total population and different gender groups showed a statistically significant upward trend as age increased (all P<0.05). The reporting peaks were primarily concentrated in the 80 years old age group. ConclusionThe age-standardized first-diagnosed reporting rate of COPD in Changzhou City exhibited a rapid upward trend from 2020 to 2024. ASFDRR was higher in males than that in females, and the elderly population constituted the main reported group. This trend warrants close attention, emphasizing the need to strengthen screening, early intervention, and standardized management for high-risk populations.

Objective To evaluate the safety and efficacy of a self-developed micro-normothermic machine perfusion (NMP) system (micro-perfusion device) for preserving isolated porcine limbs. Methods Five healthy Landrace pigs were selected, and their left and right forelimbs were randomly divided into the NMP group and static cold storage (SCS) group. The NMP group was perfused with the self-developed micro-perfusion device and polymerized hemoglobin perfusate for 32 hours at normothermia, while the SCS group was preserved at 4 ℃. Hemodynamic parameters such as perfusion pressure and flow were monitored. The pH value, partial pressure of oxygen (PO₂), lactic acid (Lac), creatine kinase (CK) and lactate dehydrogenase (LDH) in the perfusate were measured. Hematoxylin-eosin staining was used to assess the muscle tissue structure, terminal deoxynucleotidyl transferase-mediated dUTP nick-end labeling was employed to evaluate muscle cell apoptosis, and immunohistochemistry staining was applied to detect the expressions of tumor necrosis factor (TNF)-α and interleukin (IL)-6. A mixed-effects model was used to analyze the effects of time and treatment methods on tissue structure, cell apoptosis and inflammatory factors. Results The device could stably maintain a perfusion pressure of (69±15) mmHg and a flow rate of (117±42) mL/min. The pH value and electrolytes of the perfusate were generally stable, with PO₂ maintained at a high level. Lac was maintained at 5.38(3.81, 6.45) mmol/L, while CK and LDH increased over time. After 32 hours of perfusion in the NMP group, both the myocyte spacing and apoptosis rate were better than those in the SCS group. Mixed-effects model analysis showed that there were statistically significant differences in the effects of NMP treatment and SCS treatment on myocyte spacing and apoptosis rate per unit time (both P < 0.05). There were no statistically significant differences in TNF-α and IL-6 between the two groups, and mixed-effects model analysis showed no statistically significant differences in the effects of NMP treatment and SCS treatment on TNF-α and IL-6 per unit time (both P > 0.05). Conclusions The micro-perfusion device used in this study may achieve 32-hour normothermic preservation in a porcine limb amputation model, maintain basic metabolism and ionic homeostasis, reduce muscle structural damage and cell apoptosis without inducing additional inflammatory responses. This technology is expected to significantly extend the time window for replantation of amputated limbs in disaster rescue and long-distance transportation, providing an important technical basis for clinical translation and subsequent replantation research.

ObjectiveTranscranial magneto-acoustic stimulation (TMAS) is an emerging non-invasive neuromodulation technique that may provide a novel non-pharmacological intervention strategy for Parkinson's disease (PD). PD is characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra pars compacta (SNc), leading to motor impairments such as bradykinesia, tremor, and rigidity. Increasing evidence indicates that mitochondrial dysfunction and impaired mitochondrial quality control are central mechanisms underlying dopaminergic neuronal loss. In particular, abnormalities in mitophagy and mitochondrial fission-fusion balance contribute substantially to oxidative stress, energy metabolic failure, and neuronal injury. At present, most clinical treatments for PD mainly alleviate symptoms but do not effectively halt disease progression. Therefore, exploring new interventions targeting the core pathological mechanisms is of considerable significance. This study aims to investigate whether TMAS can improve neural damage and motor dysfunction in PD mice by regulating mitophagy and the fission/fusion dynamic balance, thereby providing theoretical and experimental support for its application in PD treatment. MethodsMale C57BL/6 mice were used in this study. A PD model was established by intraperitoneal injection of 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) for 7 consecutive days. After model induction, mice in the intervention group received TMAS once daily for 14 consecutive days, whereas the corresponding control group received sham stimulation. The stimulation target was positioned over the primary motor cortex (M1). Motor performance was evaluated using the pole test and the open-field test. To verify the activation effect of TMAS on the target cortical region, c-Fos immunohistochemistry was performed in the M1. To assess nigral dopaminergic neuronal injury, tyrosine hydroxylase (TH) immunohistochemistry was used to quantify TH-positive neurons in the SNc. Mitochondrial function was evaluated by measuring reactive oxygen species (ROS) levels and adenosine triphosphate (ATP) content in the SNc. Western blot was further performed to determine the expression of mitophagy-related proteins, including PINK1, Parkin, LC3-II, and p62, as well as mitochondrial dynamics-related proteins, including Drp1 and Opa1. ResultsTMAS significantly increased the number of c-Fos-positive cells in M1 (P<0.000 1), indicating effective activation of neurons in the targeted cortical region. Compared with the control group, MPTP-treated mice exhibited marked motor dysfunction, including a significant reduction in total distance traveled in the open-field test (P<0.000 1) and mean speed (P=0.000 1), as well as significant prolongation of turn time and total climbing time in the pole test (P<0.000 1). These behavioral impairments were accompanied by a substantial loss of TH-positive dopaminergic neurons in the SNc, whereas TMAS significantly increased TH-positive neuron survival (P<0.000 1). In parallel, MPTP induced a pronounced increase in ROS levels and a significant reduction in ATP content, indicating severe mitochondrial dysfunction and energy metabolism impairment (P<0.01). TMAS treatment significantly improved motor performance, as reflected by the reversal of MPTP-induced impairment in the open-field and pole tests, and significantly reduced ROS accumulation (P<0.01) while restoring ATP production (P<0.001). At the molecular level, MPTP markedly downregulated PINK1 and Parkin, decreased p62 expression, increased LC3-II accumulation, elevated Drp1 expression, and reduced Opa1 expression, whereas TMAS significantly reversed these abnormalities, suggesting restoration of mitophagy-related mitochondrial quality control and re-establishment of mitochondrial fission-fusion balance. Collectively, these findings indicate that TMAS ameliorates MPTP-induced neurotoxicity and restores mitochondrial homeostasis and energy metabolism. ConclusionTMAS effectively attenuates neural damage and improves motor dysfunction in MPTP-induced PD mice. Its neuroprotective effects are closely associated with multidimensional regulation of the mitochondrial quality control system, including restoration of PINK1/Parkin-mediated mitophagy and rebalancing of Drp1/Opa1-related mitochondrial dynamics. Rather than acting only as a symptomatic neuromodulatory intervention, TMAS may influence a key pathological axis of PD by improving mitochondrial homeostasis in SNc and protecting nigral dopaminergic neurons. These findings provide experimental evidence supporting TMAS as a promising non-invasive physical intervention for PD.

Objective:To investigate the clinical characteristics and prognosis of patients with locally advanced or metastatic pulmonary neuroendocrine tumors(NETs).Methods:The clinical records of patients with locally advanced or metastatic pulmonary NETs in Peking Uni-versity Cancer Hospital&Institute were selected from January 2014 to June 2024.The clinical characteristics,treatment,and survival pro-gnosis were then analyzed.Results:There were 32 patients,of which 18 were male and 14 female.The median age was 56 years.Nine pa-tients had typical carcinoid and 23 had atypical carcinoid,with six in stage Ⅲ and 26 in stage Ⅳ.The common metastatic sites included the bones(18 cases),lungs(8 cases),pleura(7 cases),and liver(7 cases).The median length of the measurable primary tumor was 5.2 cm,which was mostly located centrally(22 cases).Five among the 16 patients who underwent somatostatin receptor(SSTR)imaging had high SSTR ex-pression.The initial symptoms mainly included respiratory symptoms,and none of them were combined with carcinoid syndrome.For the first-line treatment,19 patients were treated with chemotherapy,seven were treated with targeted therapy,four were treated with soma-tostatin analogs(SSAs),and two were treated with surgery.The best efficacy was evaluated as a partial response in one case(3.1%),stable disease in 23 cases(71.9%),and non-evaluable or unknown in eight cases(25%)in the first-line treatment.The median progression-free sur-vival(mPFS)of patients who received first-line treatment was 5.2 months(95%CI:0.0-13.9).The PFS of targeted therapy was the longest(11.0 months,95%CI:0.0-29.6),but there was no significant difference compared with the PFS of chemotherapy and SSA groups(P>0.05).The longest PFS(24.5 months,95%CI:0.0-58.7)was found in patients treated with chemotherapy combined with radiotherapy,but there was no significant difference compared to the PFS of the combined immunotherapy and combined anti-angiogenesis groups(P>0.05).The survival rates at 1,3,and 5 years were 79.1%,65.5%,and 58.9%,respectively.Cox regression analysis did not identify independent risk factors for prognosis.Conclusions:The initial symptoms of patients with locally advanced or metastatic NETs were mainly respiratory symp-toms but without specific manifestations.Some of them were accompanied by high SSTR expression,and there was generally no carcinoid syndrome.The first-line systemic therapy mainly included chemotherapy and target therapy,with relatively low objective response and high disease control rates.Targeted therapy and combined radiotherapy have longer PFS than that of chemotherapy.The overall survival of pa-tients with pulmonary NETs was good.

OBJECTIVE To conduct a literature review of one case of follicular lymphoma complicated with iliac bone Cryptococcus neoformans infection so as to raise the understanding of such pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.METHODS The clinical data were collected from one case of follicular lymphoma patient complicated with C.neoformans infection who was treated in Xinrui Hospital of Xin-wu District,Wuxi City on Feb.24,2023 and retrospectively analyzed.All of relevant literatures regarding to the subject were retrieved in Pubmed,CNKI,Wanfang and VIP databases,and the clinical data of the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma with C.neoformans infection were screened out and summa-rized.RESULTS The case was a 28-year-old male and had the underlying disease of follicular lymphoma.The C.neoformans was detected by iliac bone histopathology and metagenome next generation sequencing(mNGS).The condition of the patient improved after the treatment with amphotericin B cholesterol sulphate com-pound and fluconazole.A total of 28 patients,with this case included,were involved in the literature review,23 of whom were male,and 5 were female,and the age ranged between 16 and 79 years old.With respect to major in-fection sites,there were 15(53.57％)cases of cerebral infection,9(32.14％)cases of blood infections,7(25.00％)cases of pulmonary infection,4(14.285％)cases of skin infections,2(7.14％)cases of muscle tis-sue infections,2(7.14％)cases of pleural effusion infections,2(7.14％)cases of bone infections and 1(3.57％)case of bone marrow infection.Totally 11 patients had disseminated Cryptococcus infection,accounting for 39.28％.CONCLUSIONS The C.neoformans infection is seldom detected in the patients with HIV-negative Hodgkin's/non-Hodgkin's lymphoma.The brain is the major infection site with the high probability of dissemina-ted infection.It is necessary for the hospital to deepen the understanding of the pathogen in the field of HIV-negative Hodgkin's/non-Hodgkin's lymphoma.

Objective To explore the influence of low-frequency repetitive transcranial magnetic stimulation(rTMS)combined with brain-computer interface rehabilitation robot in patients with upper limb motor dysfunction after stroke.Methods A total of 126 patients with upper limb motor dysfunction after stroke were divided into the combined group(61 cases,low-frequency rTMS combined with brain-computer interface rehabilitation robot on the basis of routine rehabilitation treatment)and the magnetic stimulation group(65 cases,low-frequency rTMS on the basis of routine rehabilitation treatment)according to different treatment methods,and both groups were continuously treated for 3 weeks.The upper limb motor function[upper-extremity Fugl-Meyer scale(UFMA),action research arm test(ARAT)],hand Brunnstrom staging,upper limb surface electromyography indicators[root mean square(RMS)and integrated electromyography(iEMG)of biceps brachii,triceps brachii,deltoid anterior bundle and deltoid middle bundle],cerebral artery hemodynamics[systolic blood flow velocity(Vs),resistance index(RI),mean blood flow velocity(Vm)]and ratio of fractional anisotropy(FA)of central region of brain lesion and FA of mirror-image region of healthy cerebral hemisphere(rFA)were observed before and after treatment in the two groups.Results Compared with the magnetic stimulation group,the UFMA score,ARAT score,hand Brunnstrom staging,Vs,Vm and rFA were higher after treatment in the combined group(P＜0.05).The RMS and iEMG of biceps brachii,triceps brachii,deltoid anterior bundle and deltoid middle bundle were higher in the combined group compared with those of the magnetic stimulation group(P＜0.05),while the RI was lower(P＜0.05).Conclusion Combined treatment can more effectively improve the upper limb motor function of patients,enhance hand activity ability,promote the recovery of upper limb muscle and nerve function,and regulate the hemodynamics of cerebral arteries.
