Percutaneous coronary intervention(PCI),as one of the primary approaches for revascularization,still faces complications such as restenosis,myocardial ischemia-reperfusion injury and no-reflow/slow-flow phenomena,with no currently effective interventions ensuring long-term efficacy.Based on Li Dongyuan's theory that"fire and original qi cannot coexist",this article inherited Academician Chen Keji's academic perspective on"toxin-stasis pathogenesis"and the hemodynamic characteristics of coronary arteries to propose a"four-stage pathological progression"in post-PCI patients,namely spleen-stomach impairment-original qi deficiency-endogenous yin-fire-toxin-stasis accumulation.It emphasized that the heart vessels rely on qi and blood for nourishment and patency for function,elucidated the therapeutic rationale of Danggui Buxue Decoction,and presented the self-formulated Yixin Hemai Prescription,modified through syndrome differentiation,and performed simultaneous reinforcement and dredging,in order to provide diagnosis and treatment ideas for coronary heart disease after PCI treated with TCM.

The birth weight of newborns in plateau areas was lower than that in plain areas，and showed a downward trend with the increase of altitude.The average birth weight of newborns would decrease by about 100 grams for every 1 000 meters increase in altitude.The mechanism is mainly related to maternal physiological changes caused by hypoxia at high altitude，such as reduced uterine arterial blood flow，changes in placental structure and decreased nutrient transport capacity.Studies have shown that gestational age，altitude，ethnicity，maternal age and the number of prenatal visits are the main factors affecting the birth weight of newborns.The genetic adaptation mechanism of native plateau nationalities（such as Tibetans）can partially alleviate the restriction of fetal growth caused by hypoxia，but its role in ultra-high altitude（>4 500 m）needs further study.Young or advanced maternal age（≥35 years old）and inadequate prenatal care would increase the risk of low birth weight.It is suggested to strengthen health education in plateau area，promote regular prenatal examination，and explore the genetic mechanism of plateau adaptation in order to improve pregnancy outcomes.

Objective:To investigate the clinical value of dynamic AI ultrasonic intelligent assisted diagnosis system for preoperative evaluation of thyroid nodules with diameter ≤1.0 cm.Methods:From Apr. 1, 2023, to Dec. 30, 2023, 742 thyroid nodules with diameter ≤1.0 cm were removed from 532 patients with thyroid nodule disease who received surgical treatment in the Department of Thyroid (hernia) of the First Medical Center of the Chinese People’s Liberation Army General Hospital. Among them, 423 were d≤0.5 cm. 319 cases (235 males and 507 females) with 0.5

Objective:To investigate factors influencing 18F-FDG PET/CT SUVmax,T/MB ratio and Ki-67 expression in non-Hodgkin's lymphoma(NHL),to analyze their correlations with lymphoma aggressiveness and their potential advantages in predicting therapeutic efficacy.Methods:A retrospective analysis was conducted to investigate correlations between tumor SUVmax,T/MB ratio,and Ki-67 expression with NHL aggressiveness and clinical characteristics in 99 patients;whether SUVmax,T/MB ratio and Ki-67 served as independent prognostic factors influencing therapeutic efficacy was examined,and potential utility of ΔSUVmax and ΔT/MB as biomarkers for treatment response assessment were evaluated.Results:Aggressive NHL demonstrated significantly higher SUVmax,T/MB ratio and Ki-67 level compared to indolent NHL and aggressive/indolent NHL(P<0.05).A pretreatment SUVmax≥9.05,T/MB≥5.115 or Ki-67≥55%could predict clinical remission in NHL patients post-treatment,while post-treatment reductions of ΔSUVmax≥22.65%or ΔT/MB≥34.85%were associated with achieved clinical remission.Conclusion:SUVmax,T/MB ratio and Ki-67 are closely associated with aggressiveness of NHL,which can be predicted whether NHL will be relieved after treatment.ΔSUVmax and ΔT/MB can assess whether NHL has been relieved after treatment.

Objective Investigate the clinical efficacy and application value of gasless trans-subclavian approach endoscopic surgery(GTAES)for the treatment of primary hyperparathyroidism(PHPT).Methods 55 PHPT patients who underwent unilateral parathyroid adenoma resection from January 2023 to October 2024 were absorbed.Based on surgical approaches,31 patients were divided into the traditional low-collar arc incision open surgery group(open group)and 24 patients were divided into gasless trans-subclavian approach endoscopic surgery group(endoscopic group).The perioperative data,anterior neck function recovery,and incision healing were compared between two groups.Results There were no significant differences in operation time,intraoperative blood loss,postoperative drainage volume and postoperative hospital stay between the two groups(P＞0.05).The preoperative blood calcium levels of the endoscopic group and the open group were(2.68±0.10)mmol/L and(2.63±0.16)mmol/L,respectively.The blood calcium levels on the first day after surgery were(2.39±0.12)mmol/L and(2.36±0.16)mmol/L,respectively.Preoperative parathyroid hormone(PTH)was 27.55(110.05,155.75)pg/ml in endoscopic group and 137.00(107.00,210.30)pg/ml in open group,respectively.PTH on the first day after surgery was 18.98(12.64,23.53)pg/ml and 13.85(7.36,23.23)pg/ml,respectively.Blood calcium and PTH in each group 1 day after surgery decreased compared with that before surgery,and the difference was statistically significant(P＜0.05).There were no postoperative complications such as hoarseness,bleeding and incision infection in both groups.Postoperative hand and foot numbness:5 cases(20.8％)in endoscopic group and 8 patients(25.8％)in the open group,there was no significant difference between the two groups(P=0.667).There was no significant difference in the score of neck pain 3 days after surgery between the two groups(P＞0.05).The score of swallowing tension[(1.92±1.06)points compared with(2.77±1.38)points,P=0.015]and the score of anterior neck discomfort[(1.63±0.88)points compared with(2.35±1.33)points,P=0.018]in the endoscopic group one month after surgery were better than those in the open group.There was no significant difference in the score of neck scar scale between the two groups 3 months after surgery(P＞0.05).VAS score of incision satisfaction was(9.08±0.88)in endoscopic group and(8.19±1.30)in open group,and the endoscopic group was better than the open group,the difference was statistically significant(P=0.004).Conclusion For PHPT patients caused by unilateral parathyroid adenoma confirmed through preoperative localization examination,GTAES is a safe and effective surgical approach,which offers unique advantages in intraoperative lesion identification,cosmetic outcomes of the incision,and preservation of anterior neck function,providing a new surgical option for PHPT patients.
