Diagnostic value of superb microvascular imaging and CTA combined with serum sdLDL-C for hypertension patients with ACI / 中华老年心脑血管病杂志

Objective To investigate the diagnostic value of superb microvascular imaging(SMI)grading,CT angiography(CTA),and serum small and dense low-density lipoprotein cholesterol(sdLDL-C)in elderly hypertension patients with acute cerebral infarction(ACI).Methods A ret-rospective study was conducted on 180 elderly hypertension patients admitted to our hospital from June 2021 to June 2023,and those admitted due to ACI were assigned into ACI group(95 cases)and those without into non-ACI group(85 cases).The SMI grade,CTA,and serum sdLDL-C level were compared between the two groups.ROC curve was plotted to analyze the diagnostic value of SMI grading and CTA combined with serum sdLDL-C for ACI in patients with hyperten-sion.Multivariate logistic regression analysis was employed to analyze the factors affecting the oc-currence of ACI in the patients.Results The ACI group had significantly larger proportion of hy-perlipidemia,and higher DBP,SBP,and HDL-C,and LDL-C than the non-ACI group(P＜0.05).The proportion of SMI grade 2 and grade 3 and serum sdLDL-C level were also greatly higher[35.79％vs 10.59％,43.16％vs 8.24％,(1.62±0.25)mmol/L vs(1.35±0.19)mmol/L,P＜0.01],and the proportion of SMI grade 0 and grade 1 was lower(11.58％vs 51.76％,9.47％vs 29.41％,P＜0.01)in the ACI group than the non-ACI group.ROC curve analysis showed that the AUC value of SMI grade and CTA combined with serum sdLDL-C in diagnosing ACI in patients with hypertension was 0.934(95％CI:0.897-0.972).Multivariate logistic regression analysis in-dicated that SMI grade,CTA,and sdLDL-C were risk factors for ACI in hypertensive patients(P＜0.01).Conclusion Combination of carotid artery plaque SMI grading,CTA,and serum sdLDL-C has high auxiliary diagnostic value for elderly hypertension patients with ACI.

Application experience of prelacrimal recess combined with septotomy in resection of recurrent inverted papilloma / 临床耳鼻咽喉头颈外科杂志

Objective:To investigate the effectiveness of nasal endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum in resecting recurrent nasal inverted papilloma. Methods:Patients with recurrent nasal inverted papilloma who underwent reoperation in our hospital during the past 2 years were included . The nasal septum may hinder full access to and effective treatment of the lesions at the anterior and medial wall of the maxillary sinus by endoscope, aspirator and surgical instrument in the narrow aperture of the prelacrimal recess, although these lesions could be observed by 70° nasal endoscope. Results:The nasal septum is temporarily opened on the basis of the prelacrimal recess approach, and the nasal endoscope and instrument was introduced through trans-septal window, so as to provide a better view of the operative field and the angular range of the instrument's movement. Conclusion:The recurrent nasal inverted papilloma could be successfully managed by re-endoscopic anterior lacrimal recess approach combined with temporary fenestration of the nasal septum, and no recurrence was observed during the 2-year follow-up. This surgical approach is recommended for the inverted papilla which originates from the anterior medial wall of the maxillary sinus, as the tumor can be removed completely using this surgical approach.

Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture (version 2023) / 中华创伤杂志

Femoral neck fracture (FNF) in the elderly patients is currently a major health challenge worldwide, with excessive consumption of medical resources, high incidence of complications as well as suboptimal outcome and prognosis. Hip joint arthroplasty (HJA) has been the mainstream treatment for FNF in the elderly, but the conventional surgical approaches and techniques are still confronted with a series of bottlenecks such as dislocation, limp and limb length discrepancy. In recent years, direct anterior approach (DAA) for HJA (DAA-HJA) has been a major new choice in the field of joint replacement, which achieves improved clinical effectiveness of HJA in the treatment of elderly FNF, due to the fact that DAA approach involves the neuromuscular interface and accords with the idea of soft tissue retention and enhanced recovery after surgery. However, there is still a lack of unified understanding of standard technique and procedure of DAA-HJA in the treatment of elderly FNF. Therefore, relevant experts from the Hip Joint Group of Chinese Orthopedics Association of Chinese Medical Association, Youth Arthrology Group of Orthopedic Committee of PLA, Orthopedic Committee of Chongqing Medical Association, Branch of Orthopedic Surgeons of Chongqing Medical Doctor Association and Sport Medicine Committee of Chongqing Medical Association were organized to formulate the " Chinese expert consensus on the technical standard of direct anterior hip arthroplasty for elderly femoral neck fracture ( version 2023)" based on evidence-based medicine. This consensus mainly proposed 13 recommendations covering indications, surgical plans, prosthesis selections, surgical techniques and processes, and postoperative management of DAA-HJA in elderly patients with FNF, aiming to promote standardized, systematic and patient-specific diagnosis and treatment to improve the functional prognosis of the patients.

Prevention and treatment strategies of postoperative infection after liver resection / 中华消化外科杂志

Liver resection is an important method for the treatment of benign and malig-nant hepatobiliary diseases. Due to severe surgical injury, complicated surgical procedures and operation difficulty, the postoperative complications are relatively more common, and infections are the frequent complications. Postoperative infection not only increases the economic burden and treatment difficulty of patients, but also affects the prognosis. There are many risk factors leading to postoperative infection. Controlling and improving these factors are effective measures to reduce or avoid postoperative infection. By reviewing the domestic and abroad literatures, and combined with the clinical experiences, the authors discuss the types of postoperative infection, the related risk factor and the corresponding prevention and treatment strategies after liver resection.

Quality management of helicopter emergency medical service for critically ill patients / 中国基层医药

Public health emergencies have occurred frequently in recent years, with the characteristics of difficult rescue and a complex environment. Helicopter emergency medical service is an effective way to deal with catastrophic events. The service can effectively shorten the transfer time taken for patient transfer between hospitals, directly send patients to the hospitals that meet requirements for clinical treatment, and avoid the possible delayed treatment caused by a secondary transfer. Helicopter emergency medical service in China is still in its infancy, and there are various problems in the actual operation. Strict whole process quality management is needed to achieve the expected outcome. The paper reviews the current situation of helicopter rescue for critically ill patients in China and suggests a set of quality management schemes (including base construction, rescue equipment allocation, rescue personnel selection, rescue system construction, and on-site rescue procedure standardization). Findings from this paper hope to provide evidence for the development of aviation rescue in China. This study is innovative and scientific.

Application of the Laennec capsule approach in laparoscopic anatomical sectionectomy / 中华消化外科杂志

Laparoscopic anatomic hepatectomy (LAH) has been widely approved as an essential procedure for safety and availability, and has gradually become the mainstream method of hepatec-tomy. Through a renewed understanding of the Laennec capsule, the authors have found that there exists a natural gap between the Laennec capsule and the adjacent tissues, such as Glisson pedicles and hepatic veins. Consequently, Laennec capsule can serve as the anatomical approach for LAH. The left lobe, right anterior lobe and right posterior lobe has an independent Glisson pedicle respectively, which can be used to perform Glisson pedicle transection sectionectomy via Laennec capsule approach without damaging the liver parenchyma. The exposure of hepatic veins on the detached plane can also be achieved through this approach. Laennec capsule approach provides a new idea for laparoscopic anatomic liver sectionectomy, which is safe, reliable, convenient and highly repeatable.

Expressions and Significance of Occludin and Zonula Occluden-1 in Chronic Gastritis / 胃肠病学

Background:In the pathogenesis of chronic gastritis,the changes of biological factors can affect the physiological barrier of gastric mucosa,increase the risk of injury of intercellular junctions,leading to disruption of mucosal barrier. Aims:To investigate the expressions of occludin and zonula occluden-1 (ZO-1)in chronic gastritis and their significance. Methods:A total of 82 patients with chronic gastritis from October 2014 to October 2017 at the First People's Hospital of Xiaochang were enrolled and divided into chronic non-atrophic gastritis (CNAG)group and chronic atrophic gastritis (CAG)group according to the endoscopic biopsy pathology. Forty healthy subjects were served as normal controls. Expressions of occludin and ZO-1 were examined by immunohistochemistry. Patients positive for Helicobacter pylori (Hp) infection received eradication therapy,and expressions of occludin and ZO-1 were reexamined after Hp eradication. Results:The positivity rates of occludin and ZO-1 proteins in CNAG and CAG groups were significantly lower than those in normal control group (P＜0.05). The positivity rates of occludin and ZO-1 proteins in CNAG group were significantly higher than those in CAG group (P＜0.05). The positivity rates of occludin and ZO-1 proteins in Hp-positive CNAG patients were significantly lower than those in Hp-negative CNAG patients (P＜0.05). The positivity rate of ZO-1 protein in Hp-positive CAG patients was significantly lower than that in Hp-negative CAG patients (P＜0.05). Expressions of occludin and ZO-1 proteins showed a linear trend correlation with activity of gastric inflammation (P ＜0.05);their expressions decreased significantly with the increase in activity of inflammation. The positivity rates of occludin and ZO-1 proteins in CNAG patients increased significantly after Hp eradication (P＜0.05). Conclusions:Expressions of occludin and ZO-1 are decreased in chronic gastritis,especially in CAG,and are correlated with Hp infection and activity of gastric inflammation.

The influence of autophagy-related genes about X-Ray on nasopharyngeal carcinoma CNE2 and CNE2/DDP cells / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the relationship between the radiotherapy resistance and autophagy. To provide a theoretiacal basis for drugs that regulate autophagy to improve radiotherapy sensitivity.@*METHOD@#Flow cytometry (FCM) was performed to analyze the distribution of the cell cycle of CNE2 and CNE2/DDP cells under the action of X radiation. The expression of autopagy-specific gene Beclin1 and microtubule-associated protein light chain 3β (MAPLC3β) in CNE2 and CNE2/DDP cells was determined by real time PCR and Immumofluorescence staining.@*RESULT@#CNE2/DDP and their parental CNE2 cells produced the G2-M phase arrest under the action of X radiation. With the radiation dose increasing,The cells which in the G2-M phase were more and more (P<0. 05). The G2-M phase arrest in CNE2/DDP cells was more obvious than in CNE2 cells (P<0. 05). The expression of Beclin1 and MAPLC3β in CNE2 and CNE2/DDP cells increased under the action of X radiation. What's more, the raise was more and more obvious with the increase of the irradiation dose(P<0. 05). The expression levels of Beclin1 and MAPLC3β in CNE2/DDP was lower than that in CNE2 cells (P<0. 05).@*CONCLUSION@#Autophagic cell death may be the one manner of death in nasopharyngeal carcinoma CNE2 and CNE2/DDP cells under the action of X radiation. The radiation resistance of CNE2/DDP cells may be related to the low expression of autophagy-related genes.
