As artificial intelligence technology rapidly advances, its deployment within the medical sector presents substantial ethical challenges. Consequently, it becomes crucial to create a standardized, transparent, and secure framework for processing medical data. This includes setting the ethical boundaries for medical artificial intelligence and safeguarding both patient rights and data integrity. This consensus governs every facet of medical data handling through artificial intelligence, encompassing data gathering, processing, storage, transmission, utilization, and sharing. Its purpose is to ensure the management of medical data adheres to ethical standards and legal requirements, while safeguarding patient privacy and data security. Concurrently, the principles of compliance with the law, patient privacy respect, patient interest protection, and safety and reliability are underscored. Key issues such as informed consent, data usage, intellectual property protection, conflict of interest, and benefit sharing are examined in depth. The enactment of this expert consensus is intended to foster the profound integration and sustainable advancement of artificial intelligence within the medical domain, while simultaneously ensuring that artificial intelligence adheres strictly to the relevant ethical norms and legal frameworks during the processing of medical data.

OBJECTIVE: To investigate the pathological features of blood stasis syndrome (BSS) in non-diabetic peripheral neuropathy. METHODS: Clinical data of 31 patients with non-diabetic peripheral neuropathy who had undergone nerve biopsy during December 2004 and December 2010 in Xuanwu Hospital Capital Medical University were retrospectively analyzed. According to Chinese medicine (CM) syndrome differentiation and signs, 26 patients were blood stasis type and 5 patients were non-blood stasis type. Clinical and pathological data were compared in detail. RESULTS: Clinically, although both groups shared similar symptoms of limb numbness, weakness and sensory disturbances, the prevalence of neuralgia was much grievous in BSS group (73.1%, 26/31) compared with the non-BSS group (0%, 0/5). As for signs, dermal nutrients disturbance (84.6%, 22/26), dark or purple tongue (100.0%, 26/26), and sublingual varices (80.7%, 21/26) were more common in the BSS group than the non-BSS group (0%, 60%, 20%, respectively). The prevalence of qi deficiency cases (19/26) in the BSS group was significantly higher compared with the non-BSS group (1/5). The unique histological manifestations of BSS were axonal degeneration (16/26 vs 2/5 in non-BSS group), which was the hallmark of ischemia. Cases with BSS had prominent microangiopathy (61.5%, 16/26), manifested as epineurium vasculitis (inflammatory cell infiltrated to the vessel wall, obliteration and recanalization, vascular proliferation, extravascular hemosiderin deposition), angiotelectasis, proliferation and hyaline degeneration of endoneurium capillary. In the BSS group, impaired blood-nerve barrier was indicated by sub-perineurial edema (46.2%, 11/26) and endoneurial edema (15.4%, 4/26). The Renaut body (15.4%, 4/26) and amyloid deposition (3.8%, 1/26) found in the BSS group were absent in the non-BSS group. CONCLUSIONS BBS was common in non-diabetic peripheral neuropathies. The nerves exhibited ischemic alteration of primary axon degeneration and secondary demyelination. The interstitial tissue revealed microcirculation impairment, blood-nerve barrier disturbance, amyloid deposition and proliferation changes. The high prevalence of qi deficiency also highlights the therapy of promotion of blood circulation and removal of blood stasis.

BACKGROUNDAtopic dermatitis (AD) is an inflammatory skin disease characterized by chronic recurrent dermatitis with profound itching. Most patients have personal and/or family history of atopic diseases. Several criteria have been proposed for the diagnosis of AD. Although the clinical features of childhood AD have been widely studied, there has been less large-scale study on adult/adolescent AD. The aim of this study was to investigate the clinical features of adult/adolescent patients with chronic symmetrical eczema/AD and to propose Chinese diagnostic criteria for adult/adolescent AD.

METHODSA hospital-based study was performed. Forty-two dermatological centers participated in this study. Adult and adolescent patients (12 years and over) with chronic symmetrical eczema or AD were included in this study. Questionnaires were completed by both patients and investigators. The valid questionnaires were analyzed using EpiData 3.1 and SPSS 17.0 software.

RESULTSA total of 2662 valid questionnaires were collected (1369 male and 1293 female). Of all 2662 patients, 2062 (77.5%) patients had the disease after 12 years old, while only 600 (22.5%) patients had the disease before 12 years old, suggesting late-onset eczema/AD is common. Two thousand one hundred and thirty-nine (80.4%) patients had the disease for more than 6 months. One thousand one hundred and forty-four (43.0%) patients had a personal and/or family history of atopic diseases. One thousand five hundred and forty-eight (58.2%) patients had an elevated total serum IgE and/or eosinophilia and/or positive allergen-specific IgE. Based on these clinical and laboratory features, we proposed Chinese criteria for adult/adolescent AD. Of all 2662 patients, 60.3% were satisfied with our criteria, while only 48.2% satisfied with Hanifin Rajka criteria and 32.7% satisfied with Williams criteria, suggesting a good sensitivity of our criteria in adult/adolescent AD patients.

CONCLUSIONLate-onset of eczema or AD is common. The clinical manifestations of AD are heterogeneous. We have proposed Chinese diagnostic criteria for adolescent and adult AD, which are simple and sensitive for diagnosis of adult/adolescent AD.

OBJECTIVETo explore the distribution laws of TCM syndrome types and to analyze the distribution of dynamic blood pressure curve, atherosclerosis, and age in senile hypertension patients.

METHODSTotally 1 131 senile hypertension patients were recruited from 7 provinces and municipal cities. Features of TCM syndromes, classification and distribution curves, and syndrome distribution laws were observed. The distribution curves of dynamic blood pressure, carotid atherosclerosis, and age were compared in each TCM syndrome types.

RESULTSThere were four main syndrome types in 736 cases (56.15%), i.e., excessive accumulation of phlegm-dampness syndrome (210 cases, 16.02%), yin deficiency and hyperactivity of yang syndrome (177 cases, 13.50%), Gan-Shen yin deficiency syndrome (79 cases, 6.03%), and deficiency of qi and yin syndrome (252 cases, 19.22%). Besides, there were two more sub-types, i.e., collateral obstruction by blood stasis syndrome and collateral obstruction by phlegm and stasis. Circadian blood pressure monitor was completed in 211 cases. Of them, abnormal circadian blood pressure occurred in 152 cases (accounting for 72. 38%); yin deficiency and hyperactivity of yang syndrome, excessive accumulation of phlegm-dampness syndrome, deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome were most often seen. Color ultrasound of carotid artery was performed in 660 patients of main syndromes. The incidence was quite higher in those of excessive accumulation of phlegm-dampness syndrome (182 cases, 27. 58%), deficiency of qi and yin syndrome plus collateral obstruction by blood stasis syndrome or collateral obstruction by phlegm and stasis (322 cases, 48.79%). Yin deficiency and hyperactivity of yang syndrome was dominant in patients 60 -79 years old, while deficiency of qi and yin syndrome and Gan-Shen yin deficiency syndrome were dominant in patients older than 80 years.

CONCLUSIONSExcessive accumulation of phlegm-dampness syndrome, yin deficiency and hyperactivity of yang syndrome, Gan-Shen yin deficiency syndrome, and deficiency of qi and yin syndrome were main syndrome types in senile hypertension patients. There was statistical difference in the distribution curves of blood pressure, atherosclerosis, and age of various TCM syndrome types.

OBJECTIVETo evaluate whether garlicin can prevent reperfusion no-reflow in a catheter-based porcine model of acute myocardial infarction (AMI).

METHODSTwenty-two male Chinese mini swines were randomized into 3 groups: sham-operation group (n=6), control group (n=8), and garlicin group (n=8). The distal part of left anterior descending coronary artery (LAD) in swines of the latter two groups was completely occluded by dilated balloon for 2 h and a successful AMI model was confirmed by coronary angiography (CAG) and electrocardiograph (ECG), which was then reperfused for 3 h. In the sham-operation group, balloon was placed in LAD without dilatation. Garlicin at a dosage of 1.88 mg/kg was injected 10 min before LAD occlusion until reperfusion for 1 h in the garlicin group. To assess serial cardiac function, hemodynamic data were examined by catheter method before AMI, 2 h after occlusion and 1, 2, and 3 h after reperfusion. Myocardial contrast echocardiography (MCE) and double staining with Evans blue and thioflavin-S were performed to evaluate myocardial no-reflow area (NRA) and risk area (RA).

RESULTSLeft ventricular systolic pressure and left ventricular end-diastolic pressure significantly improved in the garlicin group after reperfusion compared with the control group P<0.05) and 2 h after AMI (P<0.05). MCE showed garlicin decreased reperfusion NRA after AMI compared with the control group (P <0.05). In double staining, NRA/RA in the garlicin group was 18.78%, significantly lower than that of the control group (49.84%, P<0.01).

CONCLUSIONSGarlicin has a preventive effect on the porcine model of myocardial infarction reperfusion no-reflow by improving hemodynamics and decreasing NRA.

BACKGROUND: Acute liver failure (ALF) caused by viral and non-viral hepatitis is often accompanied with severe metabolic disorders, the accumulation of toxic substances and continuous release and accumulation of a large number of endogenous toxins and inflammatory mediators. The present study aimed to investigate the effects of various combined non-biological artificial liver treatments for patients with acute liver failure (ALF) complicated by multiple organ dysfunction syndrome (MODS). METHODS: Thirty-one patients with mid- or late-stage liver failure complicated by MODS (score 4) were randomly divided into three treatment groups: plasmapheresis (PE) combined with hemoperfusion (HP) and continuous venovenous hemodiafiltration (CVVHDF), PE+CVVHDF, and HP+CVVHDF, respectively. Heart rate (HR) before and after treatment, mean arterial pressure (MAP), respiratory index (PaO2/FiO2), hepatic function, platelet count, and blood coagulation were determined. RESULTS: Signifi cant improvement was observed in HR, MAP, PaO2/FiO2, total bilirubin (TBIL) and alanine aminotransferase (ALT) levels after treatment (P<0.05). TBIL and ALT decreased more signifi cantly after treatment in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.01). Prothrombin time (PT) and albumin were signifi cantly improved only in the PE+CVVHDF and PE+HP+CVVHDF groups (P<0.05). TBIL decreased more significantly in the PE+HP+CVVHDF group than in the HP+CVVHDF and PE+CVVHDF groups (P<0.05). The survival rate of the patients was 58.1％ (18/31), viral survival rate 36.4％ (4/11), and non-viral survival rate 70％ (14/20). CONCLUSION: Liver function was relatively improved after treatment, but PE+HP+CVVHDF was more efficient for the removal of toxic metabolites, especially bilirubin. The survival rate was significantly higher in the patients with non-viral liver failure than in those with viral liver failure.

OBJECTIVETo observe whether garlicin could ameliorate pressure overload induced myocardial fibrosis in rats through partial inhibiting transforming growth factor beta1 (TGF-beta1) mediated Smads signal.

METHODSForty male SD rats were randomly divided into 4 groups, i. e., the sham-operation group, the model group, the garlicin group, and the Tetramethylpyrazine (TMP) group, 10 in each group. The pressure overload induced myocardial fibrosis rat model was prepared using coarctation of aorta. Three days after modeling 5.0 mg/kg garlicin injection was administered to rats in the garlicin group, 20 mg/kg TMP injection to rats in the TMP group by peritoneal injection, while normal saline was peritoneally injected to rats in the sham-operation group and the model group. Four weeks after medication, the changes of myocardial collagen were observed by picrosirius red staining. The myocardial collagen volume fraction (CVF) and perivascular collagen areas (PVCA) were calculated. The serum transforming growth factor beta1 (TGF-beta1) expression was detected using ELISA. The TGF-beta1 protein expression in the myocardial tissue was observed using immunohistochemical assay. The changes of myocardial Smad2 and Smad7 mRNA expressions were detected using Real-time RT-PCR. The effects of garlicin on TGF-beta1 mediated Smad Signaling through luciferase assay were further verified using Mv1 Lu-(CAGA) 12-Luc cell line response to TGF-beta1.

RESULTSCompared with the sham-operation group, the myocardial levels of CVF and PVCA, the serum TGF-beta1 level, and the TGF-beta1 protein expression in the myocardial tissue obviously increased in the model group (P < 0.05, P < 0.01). Compared with the model group, the PVCA level, the serum TGF-beta1 level, and the TGF-beta1 protein expression in the myocardial tissue of the garlicin group and the TMP group obviously decreased (P < 0.05, P 0O 01). The Smad2 mRNA expression was up-regulated while Smad7 mRNA expression down-regulated in the model group. The Smad2 mRNA expression was obviously down-regulated in the garlicin group and the TMP group (P < 0.05). The Smad7 mRNA expression was obviously up-regulated in the TMP group (P > 0.05). One to 2 microg/mL garlicin could obviously inhibit the luciferase activities of corresponding TGF-beta1, under the stimulation of 2 ng/mL TGF-beta1 (P < 0.05).

CONCLUSIONGarlicin ameliorated pressure overload induced myocardial fibrosis in rats through partial inhibiting TGF-beta-Smads signal pathway.

Multiple primary malignant neoplasms (MPMNs) are rarely reported and it is important to give early diagnosis and proper therapy for these patients. Here reported a case of 62-year-old man with concomitant three early stage cancer lesions in upper gastrointestinal tract, all of which were detected by endoscopy. The first one was an IIc-type lesion at angular part of stomach under endoscopy, which was histologically confirmed to be a mucosal well-differentiated adenocarcinoma. The patient underwent a standard radical gastrectomy for the lesion after the failure of endoscopic treatment. The other two neoplasms were observed during follow-up and were indicated as early stage lesions by synthesizing information from endoscopy, endoscopic ultrasonography, computed tomography and biopsy. One displayed as a hyperemic patch (3 cm×4 cm in size) located at the part of esophagus 27 cm away from the incisor teeth and was proved to be moderately differentiated squamous cancer by histopathological examination. The other was an IIc-type lesion (3.0 cm×3.5 cm in size) located at the part of esophagus 36 cm away from the incisor teeth, and the biopsy result showed a poorly differentiated squamous carcinoma. Both the two lesions were treated with radical radiation because the patient refused surgery management. No recurrence of former lesions or occurrence of novel lesions were observed during post-treatment follow-up, suggesting radical radiation might be effective for this patient.

In China there exist "three high", "three low" and "three no" phenomena in hypertension, so the task of prevention and treatment of hypertension is urgent and difficult. Practices show that treatment by integrative medicine is the best way to prevent and treat hypertension. In clinics several key points should be noticed: holding the difference of therapy philosophy between Chinese medicine and Western medicine, objectively evaluating the curative efficacy of Chinese medicine and Western medicine, insisting on compatible application of Chinese herbs and Western drugs, stressing the combination of disease identification and syndrome typing, preventing and treating target organs' damage in a scientific way, and paying attention to non-drug treatment of hypertension.

BACKGROUNDPrior research about N400 has been mainly based on English stimuli, while the cognitive processing of Chinese characters is still unclear. The aim of the present study was to further investigate the semantic processing of Chinese idioms.

METHODSEvent related potentials (ERP) component N400 was elicited by 38 pairs of matching (congruent) and mismatching (incongruent) ended Chinese idioms: ending words with same phoneme but different shape and meaning (sPdSdM), with similar shape but different phoneme and meaning (sSdPdM), with same meaning but different phoneme and shape (sMdPdS), and words with different phoneme, shape and meaning (dPdSdM) and recorded by Guangzhou Runjie WJ-1 ERP instruments. In 62 right-handed healthy adults (age 19 - 50 years), N400 amplitudes and latencies were compared between matching and mismatching conditions at Fz, Cz and Pz.

RESULTSN400 showed a midline distribution and could be elicited in electrodes Fz, Cz and Pz. The mean values of N400 latencies and amplitudes were obtained for matching and mismatching ending words in healthy adults. Significant differences were found in N400 latencies and amplitudes in matching and mismatching ending-words idioms in healthy adults (P < 0.05). Compared with matching ending-words idioms, N400 latencies were prolonged and the amplitudes were increased in mismatching ones. N400s elicited by different types of stimuli showed different latencies and amplitudes, and longest N400 latency and largest N400 amplitude were elicited by ending-words with dPdSdM. No gender difference was found of N400 latency and amplitude in this study (P > 0.05).

CONCLUSIONSCompared with English stimuli, Chinese ideographic words could provide more flexible stimuli for N400 research in that the words have 3-dimension changes - phoneme, shape and meaning. Features of N400 elicited by matching and mismatching ending words in Chinese idioms are mainly determined by the meaning of the word. Some issues of N400 elicited by Chinese characters deserve further research.
