Objective To evaluate the advantages of sevoflurane inhalation anesthesia combined with lumbosacral plexus block for hip replacement in elderly patients. Methods Sixty patients of both se-xes, aged 65-85 yr, with body mass index of 18-25 kg∕m2, of American Society of Anesthesiologists physical statusⅠ-Ⅲ, scheduled for elective unilateral hip replacement, were divided into 2 groups(n=30 each)using a random number table: total intravenous anesthesia group(TIVA group)and GasMan software-guided sevoflurane inhalation anesthesia combined with lumbosacral plexus block group(SEV-B group). After the laryngeal mask airway was inserted, the patients were mechanically ventilated in both groups. Heart rate and mean arterial pressure(MAP)were recorded before anesthesia(T0), immediate-ly after insertion of laryngeal mask airway(T1), immediately after skin incision(T2), immediately after intramedullary reaming(T3), immediately after prosthesis implanting(T4), at the end of surgery(T5) and at 5 min after removal of the laryngeal mask airway(T6). The end-tidal concentration of sevoflurane at T2-5was also recorded in group SEV-B. The time for removal of the laryngeal mask airway, duration of stay in post-anesthesia care unit and first ambulation time were recorded. The consumption of anesthetics used during patient-controlled intravenous analgesia(PCIA), effective pressing times of PCIA, requirement for rescue analgesic and adverse reactions were also recorded at 24 h after surgery. The patient′s cognitive func-tion was assessed using Mini-Mental State Examination at 1 day before surgery and 1 and 3 days after surger-y, and the occurrence of postoperative cognitive dysfunction was recorded. Results Compared with group TIVA, heart rate at T1-6and MAP at T2-6were significantly decreased, and MAP at T1was increased in group SEV-B, and the time for removal of the laryngeal mask airway, duration of stay in post-anesthesia care unit and first ambulation time were significantly shortened, the consumption of anesthetics used during PCIA, effective pressing times of PCIA, requirement for rescue analgesic and incidence of adverse reac-tions were reduced at 24 h after surgery, the Mini-Mental State Examination scores were increased at 1 day after surgery, and the incidence of postoperative cognitive dysfunction was decreased at 1 day after surgery in group SEV-B(P<005). Conclusion GasMan software-guided sevoflurane inhalation anesthesia com-bined with lumbosacral plexus block can provide more accurate anesthesia management for hip replacement and promote rapid rehabilitation after surgery in elderly patients.

Objective:
To investigate the effect of early multi-dimensional cardiac rehabilitation (CR) nursing mode on patients after percutaneous coronary intervention (PCI).
Methods:
From August 2017 to July 2018, 100 patients with coronary heart disease (CHD) underwent PCI in the Department of Cardiology, the Third Affiliated Hospital of Sun Yat-sen University were selected as subjects. According to the random number table, the patients were divided into control group and observation group, 50 in each group. The control group received routine CR nursing intervention, and the observation group was given early multi-dimensional CR nursing mode for intervention. All patients were followed up for 6 months. The incidence of major cardiovascular adverse events (MACE) was observed 1 month and 6 months of follow-up. Patients with somatization were evaluated on the 2nd day after PCI and in the first month of follow-up using the Somatic Self-rating Scale (SSS). In the first month and the 6th month of follow-up, patient compliance was assessed using the 8-item Morisky Medication Adherence Scale (MMAS-8).
Results:
During the study period, 3 patients were detached from each group, and there were 47 patients in both groups who completed the study. The incidence of MACE in the control group in 1 month and 6 months was 8.51% (4/47) and 4.26% (2/47), respectively. The incidence of MACE in the observation group was 10.64% (5/47) and 4.26%, (2/47) respectively. There was no significant difference in the incidence of MACE between the two groups (

Objective To investigate the prevalence of Echinococcus infections in small rodents around human residential areas in Yushu City, Qinghai Province in 2023, so as to provide insights into precision echinococcosis control. Methods One or two quadrats, each measuring 50 m × 50 m, were randomly assigned in Shanglaxiu Township and Longbao Township, Yushu City, Qinghai Province on June 2023, respectively, and 300 plate-type mouse traps, each measuring 12.0 cm × 6.5 cm, were assigned in each quadrat. Small rodents were captured during the period between 10 : 00 and 18 : 00 each day for 4 days. Then, all captured small rodents were identified and dissected, and liver specimens with suspected Echinococcus infections were subjected to pathological examinations. The Echinococcus cytochrome c oxidase 1 (cox1) gene was amplified using PCR assay, and the sequence of the amplified product was aligned to that was recorded in the GenBank to characterize the parasite species. In addition, a phylogenetic tree of Echinococcus was generated based on the cox1 gene sequence using the neighbor-joining method. Results A total of 236 small rodents were captured in Shanglaxiu and Longbao townships, Yushu City, including 65 Qinghai voles and 51 plateau pikas in Shanglaxiu Township, and 62 Qinghai voles and 58 plateau pikas in Longbao Township, and there was no significant difference in the constituent ratio of small rodents between the two townships (χ2 = 0.294, P > 0.05). Seven plateau pikas and 12 Qinghai voles were suspected to be infected with Echinococcus by dissection, and pathological examinations showed unclear structure of hepatic lobules and disordered hepatocyte arrangement in livers of small rodents suspected of Echinococcus infections. PCR assay identified E. shiquicus DNA in 7 Qinghai voles, which were all captured from Shanglaxiu Township. Phylogenetic analysis showed that the cox1 gene sequence of Echinococcus in small rodents was highly homologous to the E. shiquicus cox1 gene sequence reported previously. Conclusion Plateau pika and Qinghai vole were predominant small rodents around human residential areas in Yushu City, Qinghai Province in 2023, and E. shiquicus infection was detected in Qinghai voles.
