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.

The effect of topical propranolol gel on the levels of plasma renin, angiotensin II (ATII) and vascular endothelial growth factor (VEGF) in superficial infantile hemangiomas (IHs) was investigated. Thirty-three consecutive children with superficial IHs were observed pre-treatment, 1 and 3 months after application of topical propranolol gel for the levels of plasma renin, ATII and VEGF in Department of General Surgery of Dongfang Hospital from February 2013 to February 2014. The plasma results of IHs were compared with those of 30 healthy infants of the same age from out-patient department. The clinical efficiency of topical propranolol gel at 1st, and 3rd month after application was 45%, and 82% respectively. The levels of plasma renin, ATII and VEGF in patients pre-treatment were higher than those in healthy infants (565.86 ± 49.66 vs. 18.19 ± 3.56, 3.20 ± 0.39 vs 0.30 ± 0.03, and 362.16 ± 27.29 vs. 85.63 ± 8.14, P < 0.05). The concentrations of VEGF and renin at 1st and 3rd month after treatment were decreased obviously as compared with those pre-treatment (271.51 ± 18.59 vs. 362.16 ± 27.29, and 405.18 ± 42.52 vs. 565.86 ± 49.66 P < 0.05; 240.80 ± 19.89 vs. 362.16 ± 27.29, and 325.90 ± 35.78 vs. 565.86 ± 49.66, P < 0.05, respectively), but the levels of plasma ATII declined slightly (2.96 ± 0.37 vs. 3.20 ± 0.39, and 2.47 ± 0.27 vs. 3.20 ± 0.39, P > 0.05). It was indicated that the increased renin, ATII and VEGF might play a role in the onset or development of IHs. Propranolol gel may suppress the proliferation of IHs by reducing VEGF.

BACKGROUNDVentricular septal rupture (VSR) remains an infrequent but devastating complication of acute myocardial infarction (AMI). The best time to undergo surgical repair is controversial and there is currently no risk stratification for patients with VSR to guide treatment. The purpose of this study was to review the clinical outcomes of 70 patients with VSR, to analyze the short-term prognosis factors of VSR following AMI, and to make a risk stratification for patients with VSR.

METHODSA total of 70 consecutive VSR patients following AMI treated in our hospital from January 2002 to October 2010 were enrolled in this study retrospectively. The difference of clinical characteristics were observed between patients with VSR who survived ≤30 days and survived >30 days. We analyzed the short-term prognosis factors of VSR and established the short-term prognosis index of VSR (SPIV) based on the Logistic regression analysis to stratify patients with VSR.

RESULTSAmong 12 354 patients with acute ST-segment elevation myocardial infarction, 70 (0.57%) patients (33 males and 37 females) were found to have VSR. The average age was (68.1±8.5) years. Fifty-four (77.1%) patients were diagnosed with an acute anterior infarction. Patients with VSR selected for surgical repair had better outcomes than patients treated conservatively; 1-year mortality 9.5% versus 87.8%, P < 0.005. Logistic regression analysis revealed that female (P = 0.013), anterior AMI (P = 0.023), non-ventricular aneurysm (P = 0.023), non-diabetes (P = 0.009), Killip class 3 or 4 (P = 0.022) and time from AMI to VSR less than 4 days (P = 0.027) were independent risk determinants for shortterm mortality. SPIV ≥9 indicates a high risk as the 30-day mortality is 77.4%; SPIV <8 indicates a low risk as the 30-day mortality is 28.6%; SPIV between 8 and 9 indicates a moderate risk.

CONCLUSIONSVSR remains a rare but devastating complication of AMI. The independent risk determinants for short-term mortality of VSR were female gender, anterior AMI, non-ventricular aneurysm, non-diabetes, Killip class 3 or 4, and the time from AMI to VSR less than 4 days. It is reasonable to take more active treatments for the patients at high risk to save more lives.

OBJECTIVETo investigate clinical characteristics and predictive factors of refractory Mycoplasma pneumoniae pneumonia (RMPP) in children so as to recognize and treat the disease earlier.

METHODThe data including febrile time, inflammatory markers (WBC, neutrophil, CRP) and radiological features of 213 children hospitalized with Mycoplasma pneumoniae pneumonia (MPP) (72 with refractory MPP and 141 with mild MPP were retrospectively analyzed). The primary diagnostic criteria of refractory MPP: the patient's condition still deteriorates after treatment with macrolides for more than 5 days. The independent variables which had significant difference in univariate analysis was analyzed by multivariate logistic regression analysis. The predictive criteria of RMPP were further applied in 100 other patients prospectively. Kappa test was used to evaluate the accuracy rate.

RESULTRefractory MPP patients: febrile time was more than 10 days, white blood cell (WBC) count was (3.8 - 18.5)×10(9)/L in peripheral blood routine test, CRP was 38 mg/L - > 160 mg/L, large lobar consolidation with high density (> 2/3 pulmonary lobe, CT value 40 - 50 HU, without air bronchogram). Mild MPP patients: febrile time was less than 10 days, CRP was often less than 40 mg/L. Independent risk factors for RMPP were febrile time, CRP, large consolidation area with high density in lungs with or without pleural effusion (OR = 1.586, P = 0.017; OR = 4.344, P = 0.001; OR = 2.660, P = 0.012), CT value 40 - 50 HU which were demonstrated by logistic regression analysis. The specificity, sensitivity and Youden index for this diagnostic test were respectively 0.96, 0.94 and 0.90 at a CRP cut off of 40 mg/L. The sensitivity, specificity, and Kappa value for the above criteria to diagnose RMPP were respectively 0.96, 0.94 and 0.9.

CONCLUSIONThe predictive factors for RMPP are febrile time (> 10 days), CRP (> 40 mg/L), large lobar consolidation with high density (> 2/3 pulmonary lobe, CT value > 40 HU with or without pleural effusion) for the purpose of treating earlier.

OBJECTIVETo discuss the safety and feasibility of aneurysm repair in vitro and renal revascularization and renal autogenous transplantation for complex renal artery aneurysm in solitary kidney.

METHODSA complex hilar renal artery aneurysm involving the bifurcation of renal artery and its branches in a solitary left kidney was diagnosed by computed tomography angiography (CTA). After temporary nephrectomy, aneurysm repair in vitro and renal revascularization were done with the kidney protected by hypothermia and continuous perfusion with preservation solution, and then the kidney was replanted into the right iliac fossa.

RESULTSThe operation was done successfully and there were no significant perioperative complications. Although a serum creatinine level temporarily exceeded above 200 micromol/L after the surgery, it recovered gradually within half a month. CTA two weeks later demonstrated patent reconstructed renal arteries and its branches and patent renal vein in the right iliac fossa, and also a patent reconstructed ureter.

CONCLUSIONSThis technique is safe and feasible to manage complex renal artery aneurysm in solitary kidney and provide an alternative for similar complex renal diseases.

OBJECTIVETo investigate the changes in the systemic inflammatory response and T cell induced immunity after systemic administration of recombinant human growth hormone (rhGH) during early postburn stage.

METHODSForty Sprague-Dawley (SD) rats were randomly divided into three groups for the study. The rats in control group (C, n = 6) were only used for the determination of plasma levels of the cytokines, such as TNFalpha, IL-2, IL-6 and CD4(+) and CD8(+) cells. The SD rats in burn with rhGH treatment group (BT, n = 18) and burn without treatment group (B, n = 18) were inflicted with III degree scalding injury on the back. rhGH was injected subcutaneously on the abdomen of the rats in a dose of 6 IU/kg for 10 days in BT group. The blood samples were harvested from the rats in the two groups for the evaluation of the above indices.

RESULTSThe plasma levels of TNFalpha, IL-2, IL-6 and CD4(+) and CD8(+) cells were increased on the 3(rd) postburn day (PBD) and decreased on the 6(th) PBD in B group, while the CD4(+) and CD8(+) cells were increased significantly and the plasma levels of TNFalpha, IL-2, IL-6 decreased obviously on the 3(rd) PBD in BT group. And the plasma levels of IL-2 and IL-6 in BT group on the 6(th) PBD showed no difference from those in C group. But the plasma TNFalpha level in BT group was evidently higher than that in B and C group on the 6(th) PBD. Furthermore, the plasma levels of TNFalpha, IL-2 and IL-6 in BT group were still increased gradually on the 10(th) PBD, while the IL-2 and IL-6 levels were decreased obviously in B group, but the TNFalpha level was increased.

CONCLUSIONSystemic administration of rhGH during different states of stress exerted different effects on T cell induced immunity and systemic inflammatory response.

Objective To investigate the relationship between quality of life and liver function in patients with chronic viral hepatitis B.Methods Psychological condition was investigated in 536 patients of chronic viral hepatitis B and 200 normal volunteers with self-administered 36-item short-form health survey questionnaire.These patients were divided into four groups based on their liver fuction normal,mild, moderate and severe damage,based on their serum activity of alanine aminotransferase(ALT)and serum level of bilirubin at the time of investigation.The patients with abnormal liver function at the beginning of the study would be retested when liver function recovered to normal level.Before and after comparison was made for those with abnormal liver function by Wilcoxon signed rank test.Trend test for the changes in liver function was performed by Jonckheere-Terpstra test.Results There was significant difference in physical functioning,role limitation due to physical health,bodily pain,general health perception,vitality,social functioning,role limitation due to emotional problems and mental health between patient with chronic viral hepatitis B and healthy volunteers.It was positively correlated with the degree of liver function damage. Scores of general health perception,role limitation due to physical health,role limitation due to emotional problems and vitality were relatively low in patients with chronic viral hepatitis B.Conclusions Quality of life in patients with chronic viral hepatitis B was far worse than that in healthy normal people,which related with their liver function.The more damage to liver function,the worse quality of life.Additional psychological treatment will be helpful for the patients with chronic viral hepatitis B other than drug treatment.

Objective To explore the approach and early effects of endovascular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Methods Six cases with portal vein stenosis of cancerous thrombus,which caused by primary hepatic carcinoma(5 cases)and eholangiocarcinoma(1 case)and the severity of stenosis showed on contrast enhanced CT were more than 75% or occluded,were performed percutaneous transhepatie or transsplenic portography.FLUENCY~(TM) endovascular stent-graft(10 mm diameter)was placed at the position of stenosis after gastroesophageal varices embolization.Portal pressure was measured pre-and post-deployment.Results Stents were successfully placed in all patients.The average portal pressure decreased from 50.7 cm H_2O(1 cm H_2O = 0.098 kPa)to 41.3 cm H_2O after endovascular stent-graft deployment.The restenosis were found in 2 cases after one month.Haematemesis and refractory aseites appeared in one case respectively,the other 4 cases showed no significant symptoms above caused by portal hypertension.Conclusion It is safe and feasible for endovaseular stent-graft deployment in the treatment of portal stenosis of cancerous thrombus.Selecting the suitable indications,the symptoms of portal hypertension can be controlled effectively.
