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 explore the clinical application value of two longitudes three transverses method in the location of the perforator of thoracodorsal artery perforator and deep wound repair. Methods: The retrospectively observational study was conducted. From December 2018 to June 2020, 17 patients with deep wounds who were admitted to the Affiliated Hospital of Zunyi Medical University met the inclusion criteria and were included in this study, including 7 males and 10 females, aged 12 to 72 years. The wound areas of patients after debridement were 7 cm×3 cm to 11 cm×7 cm. Two longitudinal lines were located through the midpoint of the armpit, the posterior superior iliac spine, and the protruding point of the sacroiliac joint, and three transverse lines were located 5, 10, and 15 cm below the midpoint of the armpit between the two longitudinal lines, i.e. two longitudes three transverses method, resulting in two trapezoidal areas. And then the thoracodorsal artery perforators in two trapezoidal areas were explored by the portable Doppler blood flow detector. On this account, a single or lobulated free thoracodorsal artery perforator flap or flap that carrying partial latissimus dorsi muscle, with an area of 7 cm×4 cm to 12 cm×8 cm was designed and harvested to repair the wound. The donor sites were all closed by suturing directly. The number and location of thoracodorsal artery perforators, and the distance from the position where the first perforator (the perforator closest to the axillary apex) exits the muscle to the lateral border of the latissimus dorsi in preoperative localization and intraoperative exploration, the diameter of thoracodorsal artery perforator measured during operation, and the flap types were recorded. The survivals of flaps and appearances of donor sites were followed up. Results: The number and location of thoracodorsal artery perforators located before operation in each patient were consistent with the results of intraoperative exploration. A total of 42 perforators were found in two trapezoidal areas, with 2 or 3 perforators each patient. The perforators were all located in two trapezoid areas, and a stable perforator (the first perforator) was located and detected in the first trapezoidal area. There were averagely 1.47 perforators in the second trapezoidal area. The position where the first perforator exits the muscle was 2.1-3.1 cm away from the lateral border of the latissimus dorsi. The diameters of thoracodorsal artery perforators were 0.4-0.6 mm. In this group, 12 cases were repaired with single thoracodorsal artery perforator flap, 3 cases with lobulated thoracodorsal artery perforator flap, and 2 cases with thoracodorsal artery perforator flap carrying partial latissimus dorsi muscle. The patients were followed up for 6 to 16 months. All the 17 flaps survived with good elasticity, blood circulation, and soft texture. Only linear scar was left in the donor area. Conclusions: The two longitudes three transverses method is helpful to locate the perforator of thoracodorsal artery perforator flap. The method is simple and reliable. The thoracodorsal artery perforator flap designed and harvested based on this method has good clinical effects in repairing deep wound, with minimal donor site damage.

OBJECTIVETo analyze virulence genes and molecular characteristics of Vibrio parahaemolyticus isolated from sporadic cases with diarrhea in tow sentinel hospitals of Shanghai, 2010-2012.

METHODSA total of 2 729 stool samples were collected from two surveillance sentinel hospitals in Shanghai 2010-2012. Vibrio parahaemolyticus strains were isolated and identified from diarrhea out patients using TCBS agar plates and biochemical reactions. Thermostable direct hemolysingene (tdh), thermostable-related hemolysin gene (trh), hemolysin gene (tlh) were detected by multiplex PCR method. Isolates were analyzed by PFGE and MLST. The PFGE profiles were analyzed using BioNumerics software.

RESULTSA total of 30 clinical Vibrio parahaemolyticus strains isolated from 2 729 stool samples. The anually Vibrio parahaemolyticus isolation rate during 2010 to 2012 were 1.1%(11/973), 1.0%(11/1 120) and 1.3%(8/636) respectively. The PCR positive rates of virulence genes tlh, tdh and trh were 100%, 97% and 0 respectively. The Vibrio parahaemolyticus strains were divided into 13 PFGE types (P1-P13)and 3 ST types (ST-189, ST-799, ST-3). Among 13 PFGE types, P4 was the main PFGE type, accounting for 30%(9/30). P9, P10 were accounting for 12% (4/30) respectively, P1, P2, P12, P13 were accounting for 7%(2/30) respectively, the others types were 3%(1/30) respectively. MLST analysis results showed there are three ST types, ST3 was 84%(25/30), ST189 and ST799 were accounting for 13% (4/30) and 3% (1/30) respectively.

CONCLUSIONThe infection rate of Vibrio parahaemolyticus was not very high from 2010-2012 in Shanghai, all strains were positive for tlh and negative for trh. ST3 was the major type of Vibrio parahaemolyticus.

Derris eriocarpa, a traditional Chinese medicine belonging to the family of Leguminosae, is widely distributed mainly over Yunnan, Guangxi and Guizhou of China. Modern pharmacological researches on this herb showed that it had extensive bioactivities, such as promoting urination, removing dampness and cough and reducing inspissated mucus and other biological activities. The extensive studies on the chemical constituents of this plant have resulted in the isolation of triterpenoids, steroids, fatty acid and others, but the flavone compounds haven't reported before. In our further research on the ethyl acetate of this plant, nine flavone compounds were obtained by column chromatography on silica gel, Sephadex LH-20, semi-prep HPLC, polyamide column chromatography and recrystallization for separation and purification. The structures were determined on the basis of extensive spectroscopic analysis, including MS, NMR experiments and comparison with spectroscopic data in the literature, respectively, as diosmetin (1), 3, 3'-di-O-methylquercetin (2), afromosin (3), 6, 3'-dihydroxy-7, 4'-dimethoxyisoflavone (4), odoratin (5), 7, 3'-dihydroxy-8, 4'-dimethoxyisoflavone (6), 6, 4'-dihydroxy-7, 3'-dimethoxyisoflavone (7), 5, 7, 4'-trihydroxy-3, 3', 5'-trimethoxyflavone (8), and alpinumisoflavone (9). All these compounds were isolated from Derris eriocarpa How for the first time. And the in vitro assays showed that compound 2 possessed moderate inhibitory activity against human cancer cells K562 and HEL.

The effect of low temperature storage on dormancy breaking, sprouting and growth after planting of Tulipa edulis was studied. The results showed that starch content and activity of amylases significantly decreased during 10 weeks of cold storage, soluble protein content raised at first then decreased, and the peak appeared at the 6th week. However, total soluble sugar content which in- creased slowly at first than rose sharply and reducing sugar content increased during the storage duration. The bulbs with cold storage treatment rooted in the 6th week, which was about 2 weeks earlier than room temperature storage, but there were less new roots in the late period of storage. After stored at a low temperature, bud lengths were longer than that with room temperature treatment. Cold storage treatment could promote earlier emergence, shorten germination time, prolong growth period and improve the yield of bulb, but rarely affect the emergence rate. It was not beneficial to flowering and fruiting. The results indicated that 6-8 weeks of cold storage was deemed to be the key period of dormancy breaking preliminary.

The study was conducted to explore the response of growth and yield of Tulipa edulis to flower bud removal and artificial pollination. And flower bud removal and artificial pollination were carried out in the squaring period and bloom stage respectively. The morphological index and biomass indicators were determined and the yield was counted in harvest time. Result showed that flower bud removal was beneficial to the growth of T. edulis, resulting in increasing growth index, biomass as well as the yield of bulb. The diameter and dry weight of T. edulis fruit by artificial pollination were increased significantly compared with the control. Seed setting percentage increased to 100%, and the number of seed as well as the single grain weight increased by 69.03% and 16.48%, respectively, which did not significantly affect the bulb production. In conclusion, Flower bud removal treatment accelerates bulb biomass increase, so as to improve its yield. Artificial pollination raised significantly seed setting percentage, seed number as well as the single grain weight.

OBJECTIVESTo analyze the long-term results of fibrin glue embolization to eliminate type I endoleaks after endovascular aneurysm repair (EVAR), and to assess the feasibility and durability of this technique.

METHODSFrom August 2002 to June 2010, among the 953 EVAR patients, 51 (5.4%) patients underwent intraoperative transcatheter fibrin glue sac embolization to resolve type I endoleak persisting after initial intraoperative maneuvers to close the leak or in necks too short or angulated for cuff placement. Computed tomographic angiography was performed to assess the outcome after 3, 6, and 12 months and annually thereafter. A retrospective study was conducted, and characteristics of the patients, intra-sac pressure, hospital course, and long-term outcomes were recorded.

RESULTSAmong the 51 patients, 19 (37.3%) patients had proximal necks long < 10 mm, and 6 (11.8%) patients had proximal neck angulation > 60°; 22 patients (3 additional iliac extension, 14 cuffs, and/or 8 stents) had been placed with additional devices. After fibrin glue injection, 50 (98.0%) of the 51 endoleaks were successfully resolved, and intra-sac pressure (including systolic, diastolic, mean pressures, pulse pressure, and the mean pressure indexes) decreased significantly in these cases. The patient who failed embolotherapy was converted to open surgery (2.0%); he died 2 months later from multiorgan failure. And other two (4.8%) patients died in the peri-operative period from myocardial infarction. The median of follow-up of 48 patients was 45 months (range 4 - 106 months). The mean maximal aneurysm diameter fell from the baseline (61.5 ± 15.2) mm to (48.8 ± 10.1) mm (P = 0.000). Three (6.2%) patients died in the follow-up duration (1 aneurysm-related, died of renal failure which was caused by the compromised renal artery). Cumulative survival was 97.9% at 1 year, 94.5% at 3 years, and 90.8% at 4 years. No recurrent type I endoleak or glue-related complications were observed in follow-up.

CONCLUSIONSFibrin glue embolization to eliminate type I endoleak after EVAR has yielded promising results in this study, and it can effectively and durable resolve the type I endoleaks. Balloon occlusion of the inflow of the endoleak must be done during glue injection, to enhance the safety and facilitate formation of a structured fibrin clot.
