Objective To analyze the urban drinking water quality and its influencing factors in Anhui Province from 2014 to 2022, and to provide a scientific basis for water quality improvement and protection. Methods The data were collected, saved and monitored according to the Standard Test Method for Drinking Water (GB/T5750-2006) and evaluated according to the Hygienic Standard for Drinking Water (GB 5749-2006). Results A total of 20 941 samples were collected, and the overall qualified rate was 84.26%. The qualified rate of urban drinking water increased from 76.9% in 2014 to 93.3% in 2022, and the qualified rate of water quality was on the rise (χ²=544.43, P＜0.01). From 2014 to 2022, the qualified rate of water quality in dry season was higher than that in wet season (χ²=35.98, P<0.001), the qualified rate of surface water was higher than that of ground water (χ²=4440.8, P<0.001), and the qualified rate of peripheral tap water was higher than that of factory water (χ²=145.1, P<0.001). Among all kinds of disinfection methods, chlorination disinfection had the highest qualified rate (χ²=1483.8, P<0.001). The qualified rate of water quality increased with the increase of the scale of water plant. Among the inspected indicators, the main unqualified indicators were chlorine dioxide (7.72%), fluoride (7.41%), free residual chlorine (3.90%), and total bacterial count (2.13%). Conclusion The passing rate of urban drinking water quality in Anhui Province is on an upward trend, and the quality of urban drinking water has improved. However, it is still important to pay attention to the problem of excessive microorganism and fluoride in water, and the quality of drinking water varies from place to place.

Objective To evaluate the surgical efficacy of unilateral pneumonectomy for the treatment of tuberculous destroyed lung, analyze the causes of severe postoperative complications, and explore clinical management strategies. Methods A retrospective analysis was conducted on the clinical data of patients with tuberculous destroyed lung who underwent unilateral pneumonectomy at the Public Health Clinical Center of Chengdu from 2017 to 2023. Postoperative severe complications were statistically analyzed. Patients were divided into a non-severe complication group and a severe-complication group, and the causes, management, and outcomes of complications were analyzed. Results A total of 134 patients were included, comprising 69 males and 65 females, with a mean age of 17-73 (40.43±12.69) years. There were 93 patients undergoing left pneumonectomy and 41 patients undergoing right pneumonectomy. Preoperative sputum smear was positive in 35 patients, all of which converted to negative postoperatively. There were 58 patients with hemoptysis preoperatively, and none experienced hemoptysis postoperatively. Postoperative incisional infection occurred in 8 (5.97%) patients, and postoperative pulmonary infection in 26 (19.40%) patients. Severe postoperative complications occurred in 17 (12.69%) patients, including empyema in 9 (6.72%) patients, bronchopleural fistula with empyema in 1 (0.75%) patient, severe pneumonia in 3 (2.24%) patients, postpneumonectomy syndrome in 1 (0.75%) patient, chylothorax in 1 (0.75%) patient, ketoacidosis in 1 (0.75%) patient, and heart failure with severe pneumonia in 1 (0.75%) patient. Perioperative mortality occurred in 2 (1.49%) patients, both of whom underwent right pneumonectomy. Multivariate logistic regression analysis revealed that a history of ipsilateral thoracic surgery, concomitant Aspergillus infection, and greater blood loss were independent risk factors for severe complications following unilateral pneumonectomy for tuberculous destroyed lung (P<0.05). Conclusion Unilateral pneumonectomy for patients with tuberculous destroyed lung can significantly improve the clinical cure rate, sputum conversion rate, and hemoptysis cessation rate. However, there is a certain risk of severe perioperative complications and mortality, requiring thorough perioperative management and appropriate management of postoperative complications.

Objective: To investigate the clinical characteristics, diagnostic approach, and multidisciplinary treatment strategy for a rare case of congenital defect presenting as a complex of hemifacial microsomia with cardiac and spinal deformities, in order to provide a reference for the clinical management of such cases Methods : The clinical data of a 9-year-old patient with hemifacial microsomia (HFM) complicated by post-operative Tetralogy of Fallot and scoliosis were retrospectively analyzed. A definitive diagnosis was established through specialized examinations, imaging studies, bone age assessment, and intellectual evaluation. The patient presented with right-sided HFM (with 3 accessory auricles, a transverse facial cleft, a microform median cleft of the upper lip, hypoplasia of the mandible and facial soft tissues, and agenesis of the right parotid gland and coronoid process), increased orbital distance, dental malalignment, congenital absence of one lateral incisor, and rampant caries in both primary and permanent dentition. The patient had undergone open-heart surgery for Tetralogy of Fallot with a patent foramen ovale four years prior and also presented with scoliosis and systemic developmental delay (bone age approximately 7 years). A retrospective analysis of the diagnosis and treatment of this type of case was conducted in conjunction with a literature review. Results: A multi-disciplinary treatment (MDT) model was adopted. The patient first received treatment for dental caries, followed by excision of the right accessory auricles, repair of the transverse facial cleft, and correction of the microform upper lip cleft under general anesthesia. A 6-month follow-up showed significant improvement in facial appearance and good recovery of oral function. The literature review indicated that hemifacial microsomia is a congenital disease characterized by the hypoplasia of multiple tissue structures on one side of the face. Its etiology may be related to impaired blood supply to the first and second branchial arches during early pregnancy. It often affects the craniofacial bones, ears, and soft tissues, leading to functional impairments in respiration, feeding, speech, and hearing, as well as psychological issues, severely impacting the quality of life in serious cases. The combination with cardiac and spinal deformities is relatively rare and requires individualized sequential treatment plans based on clinical evaluation and surgical indications. This typically includes cardiac surgical correction, spinal orthopedics, early soft and hard tissue reconstruction (e.g., distraction osteogenesis, facial cleft repair, and accessory auricle excision), orthodontic and dental management during the growth period, and final facial contouring in adulthood. Conclusion HFM can be associated with cardiac and spinal deformities, presenting with complex clinical manifestations. Early diagnosis, MDT collaboration, and sequential treatment plans are key to improving patients’ prognosis and quality of life.

Objective Network pharmacology and animal experiments were performed to study and verify the therapeutic effect of Rhizoma Chuanxiong volatile oil on angina pectoris.Methods Volatile oil components were screened using steam distillation,gas chromatography-mass spectrometry,and oral bioavailability.Targets of these components were identified using Pubchem,SwissTarget,DisGeNET,and DrugBank databases as well as R language.Angina pectoris-related targets and intersection targets were obtained.Protein-protein interactions were analyzed using the STRING database.The ClusterProfiler package in R was used to analyze the gene ontology and Kyoto Encyclopedia of Genes and Genomes enrichment of the intersecting targets,and Cytoscape was used to construct herbal-component-target-pathway networks.Molecular docking analysis was conducted using AutoDock Vina 1.2.3,Pymol 3.0,and Discovery Studio 2016 software to evaluate the affinity between key targets and the main volatile oil components.Finally,the therapeutic effect of Rhizoma Chuanxiong volatile oil on angina pectoris was verified by animal experiments.Results In total,10 volatile oil components and 22 key targets were identified.They were closely related to neurotransmitters,receptors on synaptic membranes,material metabolism,neuroactive ligand-receptor interaction,retinol metabolism,and drug metabolism-cytochrome P450 pathways.The molecular docking result showed that 3-butylidenephthalide,alpha-selinene,trans-ligustilide,and other volatile oil components combined with several key targets play therapeutic roles.Animal experiments showed that the volatile oil of Rhizoma Chuanxiong can regulate the ejection fraction,fractional shortening,stroke volume,and left ventricular internal diameter in systole and the activities of lactate dehydrogenase,creatine kinase and aspartate aminotransferase;promote the expression of ADRA1A and CHRM5 proteins in damaged cardiomyocytes;improve the state of myocardial fibers;reduce intercellular space;and reduce inflammatory cell infiltration.Conclusions The volatile oil of Ligusticum wallichii can effectively protect damaged myocardial tissue and thus has a role in treating angina pectoris.

Objective:To evaluate the effect of intermittent fasting on postoperative cognitive function in aged rats and the role of Janus kinase 2/signal transducer and activator of transcription 3 (JAK2/STAT3) signaling pathway in it.Methods:Eighty SPF healthy male Sprague-Dawley rats, aged 20 months, weighing 600-650 g, were divided into 4 groups ( n=20 each) using a random number table method: control group (group C), postoperative cognitive dysfuction (POCD) group (group P), intermittent fasting + POCD group (group IF+ P), and intermittent fasting+ JAK2/STAT3 signaling pathway agonist C-A1+ POCD group (group IF+ A+ P). IF+ P group and IF+ A+ P group underwent a 4-week intermittent fasting procedure: fasting for 24 h followed by free eating for 24 h, without limiting water intake throughout the entire process, in addition C-A1 100 μg/kg was intraperitoneally injected daily during intermittent fasting in IF+ A+ P group. Rats underwent exploratory laparotomy under sevoflurane anesthesia to prepare POCD models in P group, IF+ P group and IF+ A+ P group. Three days after surgery, open field tests were conducted to evaluate the autonomous motor function of rats, and Morris water maze tests were conducted to evaluate the cognitive function of rats on 3-7 days after surgery. After the Morris water maze tests, the rats were sacrificed and the hippocampal CA1 area was removed for determination of the expression of JAK2, phosphorylated JAK2 (p-JAK2), STAT3, and phosphorylated STAT3 (p-STAT3) (by Western blot) and contents of interleukin-6 (IL-6), IL-1β and tumor necrosis factor-alpha (TNF-α) (by enzyme-linked immunosorbent assay) and for microscopic examination of pathological changes of hippocampal CA1 region (using HE staining). Results:There was no statistically significant difference in the speed, distance and duration of stay at the center of the open field test among the four groups ( P>0.05). Compared with group C, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and contents of IL-6, IL-1β and TNF-α in the hippocampal CA1 region were increased ( P<0.05), and the pathological damage occurred in the hippocampal CA1 region in group P. Compared with P group, the escape latency was significantly shortened, the number of crossing the original platform was increased, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and contents of IL-6, IL-1β and TNF-α in the hippocampal CA1 region were decreased ( P<0.05), and the pathological damage in the hippocampal CA1 area was significantly alleviated in IF+ P group. Compared with IF+ P group, the escape latency was significantly prolonged, the number of crossing the original platform was reduced, and the p-JAK2/JAK2 ratio, p-STAT3/STAT3 ratio and contents of IL-6, IL-1β and TNF-α in the hippocampal CA1 region were increased ( P<0.05), and the pathological damage in the hippocampal CA1 area was aggravated in group IF+ A+ P. Conclusions:Intermittent fasting can improve postoperative cognitive function in aged rats, and the mechanism may be related to inhibiting the JAK2/STAT3 signaling pathway and reducing the neuroinflammatory responses in the hippocampal CA1 region.

Objective:To evaluate the effect of preoperative mild cognitive impairment (MCI) on the potency of sevoflurane in inhibiting body movement responses during skin incision in aged female patients.Methods:This was a prospective study. Female American Society of Anesthesiologists Physical Status classification Ⅰ or Ⅱ patients, aged 60-75 yr, with body mass index of 18.5-23.9 kg/m 2, scheduled to undergo radical mastectomy between January 2022 and March 2023 in our hospital, were selected. The patient′s cognitive function was assessed using Mini-Mental State Examination and Montreal Cognitive Assessment. The patients were divided into 2 groups based on whether they had MCI or not before operation: normal group (group N) and MCI group (group M). General anesthesia was induced by inhaling 8% sevoflurane, and the laryngeal mask airway was inserted after they lost consciousness and their jaws relaxed. According to the Dixon′s up-and-down method, the end-tidal concentration of sevoflurane in the first patient was set at 2%. If the body movement response occurred, the concentration was increased by 2% in the next patient, otherwise the concentration was decreased by 2% in the next patient. The MAC and 95% confidence interval ( CI) of sevoflurane were calculated using the probability regression method. Results:The minimum alveolar concentration of sevoflurane was 1.60% (95% CI 1.48% -1.70%) in group N and 1.38% (95% CI 1.25%-1.49%) in group M, and there was statistically significant difference ( P<0.05). Conclusions:Preoperative MCI can increase the potency of sevoflurane in inhibiting body movement responses during skin incision in aged female patients.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To analyze the influencing factors of coronary artery lesions in patients with Ka-wasaki disease(KD)in Xinjiang.Methods A total of 1 500 KD patients who were treated in the First Affilia-ted Hospital of Xinjiang Medical University from December 2020 to December 2022 were selected as the re-search objects.According to whether coronary artery disease occurred,they were divided into two groups.886 patients with coronary artery lesions were included in the experimental group,and 614 patients without coro-nary artery lesions were included in the control group.Univariate and multivariate logistic regression analysis was used to analyze the risk factors of coronary artery lesions.Results The results of logistic regression anal-ysis showed that the duration of fever(＞10 d),high Gensini score,high level of N-terminal pro-brain natri-uretic peptide(NT-proBNP),C-reactive protein(CRP),total cholesterol(TC),low-density lipoprotein cho-lesterol(LDL-C)and triglycerides(TG)may be risk factors for coronary artery lesions(P＜0.05).Conclusion In clinical diagnosis and treatment,targeted intervention should be given as early as possible to prevent the occurrence of coronary artery lesions.

Objective To analyze the problems of review of anti-tumor drug prescriptions and medical orders assisted by an information system to improve the review rules,and to provide a reference for improving review quality of anti-tumor drug prescription.Methods The problem with the pre-review of anti-tumor drug prescriptions and medical orders assisted by the information system in Sichuan Cancer Hospital during 2020-2022 were collected.The data came from the MEDICOM PASS system in Sichuan Cancer hospital.Clinical pharmacists made comments on relevant problems and analyzed the results.Results A total of 9 325 antitumor drug pre-approval problems,including 6 279 outpatient prescriptions(67.3%)and 3 046 inpatient orders(32.7%),among which 6 153(66.0%)were unsuitable indications,1 933(20.7%)were drug contraindications,449(4.8%)were problematic routes of administration,345(3.7%)were unsuitable drug compatibility,177(1.9%)were inappropriate drug frequency,133(1.4%)were problematic drug populations,74(0.8%)were unsuitable single doses,39(0.4%)were unacceptable drug interactions,22(0.2%)were unsuitable drug total.The results of clinical pharmacists'comments were 4 459 reasonable cases,with a false positive rate of 47.8%.The false positive problems included 2 264(50.8%)cases of unsuitable indications,1 933(43.3%)cases of drug contraindications,231(5.2%)cases of problematic routes of administration,and 31(0.7%)cases of unsuitable populations.Conclusion The review of anti-tumor drug prescriptions assisted by an information system can effectively intercept irrational drug use and improve the review quality of prescriptions and medical orders.However,the evidence-based medicine date of antitumor drugs is updated quickly.Pharmacists should constantly improve the prescription review rules based on the latest evidence-based medicine data.
