Objective To explore the potential categories of frailty development trajectories in patients undergoing cardiac surgery from pre-operation to 6 months post-operation,and analyze the influencing factors.Methods By a longitudinal study design,patients undergoing elective heart valve replacement surgery or coronary artery bypass grafting in a tertiary general hospital in Zunyi City from August 2022 to June 2023 were selected by the convenience sampling method.Tilburg frailty scale was used to investigate the frailty level of cardiac surgery patients 1 day before surgery(T0),1 month(T1),3 months(T2)and 6 months after surgery(T3).The growth mixture model was used to identify the trajectory categories,and the influencing factors of different frailty trajectories were analyzed by binary Logistic regression.Results 261 patients were enrolled at T0,with 22,9,and 3 patients lost at T1 to T3,and 227 patients were finally included in the analysis.There were 2 types of trajectories being identified as the low frailty decline group and the high frailty maintenance group.Age,use of sedative and analgesic drugs,pace,and depression were the factors influencing the frailty in cardiac surgery patients(P＜0.05).Conclusion There are 2 kinds of frailty development trajectories in patients undergoing cardiac surgery.Medical staff should fonnulate precise interventions and nursing measures according to the factors influencing frailty,so as to improve frailty degree and quality of life of patients undergoing cardiac surgery.

Objective:To improve the prevention and treatment of venomous snake bites by analyzing the epidemiological characteristics of venomous snake bite in Wuzhou City, Guangxi Zhuang Autonomous Region.Methods:A retrospective analysis was conducted. The medical records of 1 091 patients with venomous snake bites admitted to the department of snake wound of Wuzhou Hospital of Traditional Chinese Medicine from January 2014 to December 2020 were collected, including snake species, gender and age of patients, bite time, bite site and local symptom.Results:The medical records of 952 patients with a definite clinical diagnosis of snake bite were enrolled. Among the 952 patients with venomous snake bites, the main bites were from Ovophis (32.98%), Trimeresurus (27.84%) and Naja (26.26%), followed by Bungarus multicinctus (6.51%), Ophiophagus Hannah (3.15%) and Agkistrodonhalys (1.58%), and few bites were from Rhabdophis subminiatus (0.73%), Bungarus fasciatus (0.42%), viper (0.32%) and Agkistrodon (0.21%). Of the 952 patients with venomous snake bites, there were almost twice as many males as females [647 cases (67.96%) vs. 305 cases (32.04%), with male to female ratio of 2.12∶1]. The age of patients ranged from 0.8 to 87.0 years old, with 40-59 years old as the majority (42.44%), followed by ≥ 60 years old (27.31%). Snake bites mainly occurred from April to November (93.59%), with a peak in October (16.39%). The incidence time was mainly afternoon (12:00-17:59, 30.88%) and evening (18:00-23:59, 33.30%), followed by morning (06:00-11:59, 24.69%), and early in the morning (00:00-05:59, 11.13%). The incidence time of Ovophis and Bungarus multicinctus mainly concentrated in 18:00-23:59, the time of Trimeresurus was in 06:00-11:59, and that of Naja and Ophiophagus hannah was in 12:00-17:59. Most cases of snake bite were on limbs (98.53%), and mainly on the right limbs (53.57%). The lower limbs mainly were bitten by Ovophis, while the upper limbs mainly were bitten by Naja and by Ophiophagus hannah. The local symptoms of the bite of Ovophis and Trimeresurus were similar, mainly including pain, swelling, tenderness, high temperature of skin around the wound, bleeding and exudation, etc. And the local symptoms of the bite of Naja were pain, swelling, bruising, tenderness, bleeding and exudation, red skin, etc. Numbness and mild pain were the main symptoms of the bite of Bungarus multicinctus and Bungarus fasciatus, but other local characteristics were not obvious.Conclusions:The majority of venomous snake bite patients in Wuzhou City of Guangxi were middle-aged and elderly males, and the majority of venomous snakes were Ovophis, Trimeresurus, and Naja. Most venomous snake bite occurs from April to November, and the incidence time was concentrated between 12:00 and 23:59. The majority of venomous snake bite was limb bites. The local symptoms were pain, swelling, tenderness, high temperature of skin around the wound, bruising, etc. To reduce the incidence rate, disability rate and mortality of snake bite disease, a snake bite prevention system should be established, the education and publicity of snake bite prevention knowledge should be strengthened, the awareness of snake bite prevention should be improved, and clinical diagnosis and treatment should be assisted, based on the epidemiological characteristics of snake bite in Wuzhou area.

OBJECTIVE: To provide reference for the improvement of management quality of high-alert medications in ward area. METHODS: Risk management was used to estimate risk factor of commonly used high-alert medications in ward area. Then the homologous management measures were formulated based on potential risk. RESULTS: With enforcement of risk management, risk awareness of relevant responsible person was strengthened. They knew more knowledge about high-alert medications and its rate increased from 60% to 96%. The phenomena such as nonstandard storage and placement of drugs, unclear identification had never happened again. CONCLUSION: The application of risk management in high-alert medications contributes to improve anti-distress awareness of relevant responsible person, guarantee safety of drug use and enhance the quality of care.

Objective To study the result of DSA for 56 cases with large liver cancer that there is bloody supply from arteria musculophrenica right and the clinical value of super selective interventional embolization,so that to improve the clinical curative effects of interventional therapy. Methods Employ 4F, 3F catheter super selectively into arteria musculophrenica that supply blood to cancer. Result 56 cases(21.7% )were discoverod that there was bloody supply from arteria musculphrenica right to cancer in 258 cases with large liver cancer, liver neoplastic size of all cases wasin 5～15cm,22 cases(8.6% ) were discovered in the first interventional operation,34 cases ( 13.3% )were discovered in the second or the third interventional operation. Obvious tumor shrinking in all cases: the 6month survival as 56 cases(100 % ), the 1-year survival as 45 cases (80.4%), the 2-year survival as 21 cases(37.5%). Conchssion Arteria musculophrenica right supply blood to cancer is common in large liver cancer eases, super selectively embolized the supply blood from the arteria musculophrenica right is very important for acquiring success by interventional operation.
