RESUMEN
Objectives: To investigate the efficacy and safety of endotracheal intubation combined with deep analgesia and sedation in the prevention of preoperative dissection rupture in acute Standford type A aortic dissection. Methods: This study evaluated the impact of preoperative endotracheal intubation combined with deep analgesia and sedation on acute Stanford Type-A aortic dissection. Conducted at the First Affiliated Hospital of the University of South China's cardiac intensive care unit from June 2018 to December 2021, 134 diagnosed patients participated. They were divided into experimental (n=42) and control (n=92) groups. Data collected included clinical details, biochemical markers, VAS and SAS scores, and preoperative dissection rupture occurrences. Criteria involved acute Stanford Type-A aortic dissection diagnosis and complete data. Exclusions encompassed rupture, vital sign instability after vasoactive drugs, or prolonged coma. Standardized methods were used for sample collection and analysis. The study's design, duration, and location ensured comprehensive evaluation of the intervention's effects on patients. Results: The experimental group showed significantly fewer deaths due to dissection rupture compared to the control group (P < 0.05). Initial VAS and SAS scores (T0) were similar between groups (P > 0.05), indicating good comparability. However, at T1, T2, and T3, analgesia and sedation were significantly better in the experimental group (P < 0.05). By T4, patient numbers were too low in both groups for a significant difference (P > 0.05). Conclusion: Preoperative endotracheal intubation combined with deep analgesia and sedation in patients with acute Stanford Type-A aortic dissection can produce good analgesic and sedative effects, effectively reduce the incidence of preoperative dissection rupture, and create conditions for subsequent surgical treatment of patients.
RESUMEN
Background: Zoster-associated pain (ZAP) is often refractory to conventional treatments and can seriously affect patients' physical and mental health. High-voltage pulsed radio frequency (H-PRF) is a new method for treating ZAP with pulse voltages above 60 V or even up to 100 V. The purpose of this paper was to conduct a systematic review and meta-analysis to evaluate the efficacy of H-PRF in the management of ZAP. Methods: PubMed, Embase, and the Cochrane library were searched from their inception to June 2022 to identify controlled trials which evaluated the effectiveness of H-PRF compared with standard PRF and sham operations. The primary outcome was pain scores at different treatment times. The secondary outcomes included SF-36 scores, rescue analgesic dose, and side effects. Results: We reviewed 6 randomized controlled trials involving 428 patients. There was no significant difference between the H-PRF and standard PRF pain scores at 1 week after surgery and the sham operation group at 1 month. At 1, 3, and 6 months, the H-PRF group had better pain score than the standard PRF group, and at 3 months, the pain score was better than the sham operation group. The H-PRF group showed improvement in the SF-36 score, and there were no significant complications in the H-PRF group. Conclusions: H-PRF is an effective and safe treatment method that has better effects in relieving pain and improving the quality of life and physical and mental health. Although H-PRF provides pain relief rates comparable to those of the control group in the early stages, it remains the preferred and alternative treatment for relieving herpes zoster-related pain.

Objective To study the prevalence of hyperuricemia and its risk factors in elderly people of Yiyang District,Hunan Province,China.Methods A total of 1363 elderly people undergoing physical examination in our hospital were divided into hyperuricemia group (n=245) and control group (n=1118).Their general clinical data were recorded and compared.The risk factors for hyperuricemia were analyzed.Results The age was significantly older,number of males was significantly larger,the serum TG,LDL-C,urea,UA levels and body height,BMI,SBP were significantly higher while the serum TC and HDL-C levels and Cr clearance rate were significantly lower in hyperuricemia group than in control group (P＜0.05,P＜0.01).Pearson correlation analysis showed that serum UA level was positively related with age,serum TG and urea level,BMI,SBP and DBP,but negatively related with Cr clearance rate and serum TC,LDL-C,HDL-C levels (P＜ 0.01).Binary logistic regression analysis showed that age,male gender,hyperlipidemia,and obesity were the independent risk factors for hyperuricemia after adjustment of age (OR=1.857,95 ％ CI:1.302-2.649,P=0.001;OR=1.866,95％CI:1.363-2.555,P=0.000;OR=2.214,95％ CI:1.716-2.856,P=0.000).However,serum HDL-C level and Cr clearance rate were the protective factors for hyperuricemia (OR =0.388,95 ％ CI:0.242-0.623,P =0.000;OR =0.948,95％CI:0.937-0.959,P=0.000).Conclusion The prevalence of hyperuricemia is rather high in elderly people of Yiyang Distric,Hunan Province,China,suggesting that the lifestyle of elderly people should be improved and hyperuricemia should be treated with appropriate drugs.
RESUMEN
Objective To compare and explore the morphological characteristics of mast cells in different tissues of 6 types of common laboratory animals.Methods Ten healthy adult SPF Kunming mice, 10 SD rats, 10 Hartley guinea pigs, 10 New Zealand rabbits, 6 beagle dogs and 6 Macaca mulata ( male:female=1:1, for all) were used in this study. The animals were sacrificed by euthanasia, samples of the skin, lung, spleen and sigmoid colon were taken from mouse, rat, guinea pig, rabbit, dog and monkey, and fixed in formalin and Bouin’ s solution.Paraffin sections were stained with toluidine blue and Alcian blue-safranin O, respectively.The mouse skin and dog spleen were immunohistochemically stained for substance P.A color pathological image analysis system was used to conduct the analysis of morphometric pa-rameters of mast cells.Samples of the skin of these animals were also fixed in glutaraldehyde for the electron microscopic observation and comparison of the mast cells.Results Mast cells in different types of animals were distinctive in distribu-tion, morphology, size, metachromasia and staining properties.Density and morphometric parameters of the mast cells had significant differences among the 6 types of animals ( P＜0.05 ) .Characteristic granules were contained in the skin mast cells of guinea pig, dog and monkey.Mast cells in the mouse skin, dog spleen and nerves in the mouse skin showed immu-noreactive substance P.Conclusions Mast cells in the 6 types of laboratory animals showed histochemical and morphologi-cal heterogeneity, which have important reference values in animal experimental research on mast cell function.

Objective To investigate the clinical efficacy of fire needling in treating endometriosis.Method Fifty-eight endometriosis patients were randomly allocated to treatment and control groups. The treatment group received fire needling at specific points. The treatment was given at one week before menstruation until the end of it, twice a week, three months as a course. The control group took gestrinone 2.5 mg from the first day of menstruation, twice a week, for three consecutive months. The therapeutic effects were evaluated in both groups at three months after the end of treatment.Result The cure rate and the efficacy rate were significantly higher in the treatment group than in the control group (P＜0.05). The pregnancy rate was also higher in the treatment group than in the control group (P＜0.05).Conclusion Fire needling treatment for endometriosis has the advantages of good therapeutic effect, high cure rate and no influence on pregnancy.
