Compared to traditional suturing, lung stapling using automatic staplers offers advantages such as smaller trauma, faster wound healing, ease of operation, and lower complication rates, making it widely used in clinical practice. However, there are significant differences in bronchial tissue thickness at different anatomical locations, and the market is flooded with various types of staplers. Currently, there is a lack of recommended stapling schemes for bronchial staplers at different anatomical locations. This article reviews the development and application of automatic staplers and summarizes some types of staplers that are currently used in clinical practice, with the aim of promoting the formation of individualized stapler selection protocols for minimally invasive thoracic surgery based on the Chinese population.

The liver regenerative capacity is crucial for patients with end-stage liver disease following partial hepatectomy (PHx). The specific bacteria and mechanisms regulating liver regeneration post-PHx remain unclear. This study demonstrated dynamic changes in the abundance of Parabacteroides distasonis (P. distasonis) post-PHx, correlating with hepatocyte proliferation. Treatment with live P. distasonis significantly promoted hepatocyte proliferation and liver regeneration after PHx. Targeted metabolomics revealed a significant positive correlation between P. distasonis and β-hydroxybutyric acid (BHB), as well as hyodeoxycholic acid and 3-hydroxyphenylacetic acid in the gut after PHx. Notably, treatment with BHB, but not hyodeoxycholic acid or 3-hydroxyphenylacetic acid, significantly promoted hepatocyte proliferation and liver regeneration in mice after PHx. Moreover, STAT3 inhibitor Stattic attenuated the promotive effects of BHB on cell proliferation and liver regeneration both in vitro and in vivo. Mechanistically, P. distasonis upregulated the expression of fatty acid oxidation-related proteins, and increased BHB levels in the liver, and then BHB activated the STAT3 signaling pathway to promote liver regeneration. This study, for the first time, identifies the involvement of P. distasonis and its associated metabolite BHB in promoting liver regeneration after PHx, providing new insights for considering P. distasonis and BHB as potential strategies for promoting hepatic regeneration.

Calorie restriction has garnered significant attention in the prevention and treatment of metabolic diseases. During calorie restriction, various appetite-regulating hormones undergo changes, including a decrease in leptin, insulin, and amylin, along with an increase in peptide YY, glucagon-like peptide 1, and pancreatic polypeptide. These hormonal changes play a crucial role in regulating the body's feeding processes, improving glucose and lipid metabolism, and maintaining energy balance. In this paper, we discuss the effects of dietary restriction therapy on appetite-regulating hormones and the mechanisms by which this therapy aids in the treatment of metabolic diseases. Our goal is to provide insights for the prevention and long-term management of metabolic disorders such as obesity and type 2 diabetes.

Objective:To investigate the alteration in iodine nutritional status and influence on thyroid function in the elderly aged≥65 years following water source modification in high iodine areas.Methods:Data from Yaoji Town, Xuzhou, Jiangsu(an area with high iodine due to water sources) of the national epidemiological survey on thyroid diseases, iodine nutrition, and diabetes(TIDE study) in 31 provinces and cities in China from 2015 to 2017 were utilized. Additionally, data from the screening, monitoring, and intervention on thyroid diseases(TOPS study) in the elderly(≥65 years) in Shunhe Town, Suqian, Jiangsu(an area with iodine levels exceeding the recommended amount), and Yaoji Town, Xuzhou from May to August 2021, are included. Each subject completed a questionnaire, physical examination, laboratory tests and thyroid ultrasound examinations. A total of 2 717 subjects aged≥65 years were included, including group 1, 258 subjects in TIDE study; Group 2, 1 313 subjects in TOPS Xuzhou area; Group 3, 1 146 subjects in TOPS Suqian area.Results:The urinary iodine concentration(UIC) in group 2 was significantly lower than that in group 1 [(235.16±67.09)μg/L vs (491.58±384.93)μg/L, P<0.001], but no significant difference compared with group 3 [(235.16±67.09) μg/L vs(231.62±66.11) μg/L, P>0.05]. The serum TSH level in group 2 was significantly lower than that in group 1 [(2.92±5.14)μIU/mL vs (4.15±9.19)μIU/mL, P<0.001]. Compared with group 2 and 3, the prevalence of subclinical hypothyroidism in the elderly in group 1 was the highest(22.48% vs 10.13% and 8.12%, P<0.001). TSH levels were linearly correlated with age in both excessive iodine and more than adequate iodine nutrition areas. TSH level was gradually increased with age. Conclusion:The alteration in TSH levels among the elderly is notably linked to both aging and iodine status. The prevalence of hypothyroidism in the elderly can be significantly reduced when the iodine nutrition status of the elderly returns to normal.

Objective:To compare the short-term efficacy and the safety of microwave ablation (MWA) and radiofrequency ablation (RFA) in the treatment of benign thyroid nodules (BTNs).Methods:This prospective randomized controlled trial, performed from December 2019 to September 2021, included 36 patients with solid or predominantly solid BTNs who met the eligibility criteria and provided written informed consent at the Nanjing sub-center (Affiliated Hospital of Integrated Traditional Chinese and Western Medicine, Nanjing University of Chinese Medicine). Patients were assigned to either the MWA group or the RFA group (18 patients in each group) at a ratio of 1∶1 using a block randomization design and allocation concealment using sealed envelope randomization. The independent-sample t-test and χ2 test were used to compare the volume reduction rates (VRRs), effective rates (VRRs≥50%), cosmetic scores, and complication rates at 1, 3, and 6 months after treatment between the two groups. Results:The clinical characteristics of the two groups of patients were comparable. After ablation, the nodule volume was significantly reduced in both groups. At 1, 3, and 6 months, there was no significant difference in the volume between the two groups (all P>0.05). At 3 months, the RFA group had a larger VRRs than that in the MWA group (62.08%±12.46% vs. 46.90%±23.16%, t=-2.45, P=0.021). However, at 1 and 6 months, no statistical significance was observed (both P>0.05). No significant difference was observed in the effective rates at the last follow-up (14/18 vs. 18/18, P=0.104). However, the RFA group had a lower cosmetic score than that in the MWA group (1.78±0.43 vs. 2.17±0.51, t=-2.47, P=0.019). There was no statistically significant difference in the complication rates between the two groups (all P>0.05). Conclusions:Both MWA and RFA were effective and safe treatments for BTNs, with no significant differences in short-term efficacy and safety. In addition, the RFA group showed slightly more favorable outcomes than the MWA group in terms of cosmetic improvement.

Objective:To observe the effects of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor combined with rosuvastatin on lipid levels and short-term prognosis in patients with acute ischemic stroke, and to explore the optimal therapeutic regimen in terms of efficacy and safety, so as to provide a basis for clinical practice.Methods:Consecutive patients with acute cerebral infarction within 72 hours of onset and lipids≥2.6 mmol/L admitted to Xuzhou Central Hospital from April 2022 to March 2023 were included in the study, and the randomized numeric table method was used to divide them into 3 groups of different treatment regimens, group A (rosuvastatin 20 mg, once a day), group B (rosuvastatin 10 mg, once a day+alirocumab 75 mg, once 2 weeks) and group C (rosuvastatin 20 mg, once a day+alirocumab 75 mg, once 2 weeks). General baseline data, National Institutes of Health Stroke Scale score, modified Rankin Scale score on day 90 and the occurrence of adverse events and serious adverse events were collected from the 3 groups. The primary efficacy outcome was the degree of reduction in low density lipoprotein-cholesterol (LDL-C) from baseline on day 90. The secondary efficacy outcomes were recurrence rate and time to recurrence in stroke patients within 90 days,etc. The primary safety outcome was hepatic insufficiency (transaminase elevation≥3 times normal) within 90 days. The secondary safety outcomes were death due to stroke within 90 days and fatal and nonfatal myocardial infarction.Results:A total of 501 patients were included, 166 patients in group A, 167 patients in group B, and 168 patients in group C. The differences in the baseline data of the 3 groups were not statistically significant (all P>0.05). LDL-C was reduced from baseline on day 90 in groups A, B, and C, with the differences of -1.5 (-1.7, -1.4) mmol/L, -2.2 (-2.5, -2.1) mmol/L and -2.2 (-2.6, -2.1) mmol/L, respectively, with statistically significant differences among the 3 groups ( H=1.497, P<0.001); the differences between the group A and group B, and between the group A and group C, were statistically significant ( Z=-11.125, P=0.006; Z=-9.475, P=0.012), while the difference between the group B and group C was not statistically significant ( Z=1.650, P=0.946). The numbers of 90-day stroke recurrence cases (recurrence rate) in patients in the groups A, B, and C were 12 (7.2%), 4 (2.4%), and 5 (3.0%), respectively, without statistically significant difference among the 3 groups ( χ 2=5.773, P>0.05); the recurrence time of patients in the groups A, B and C was (43.0±7.4) d, (66.0±8.3) d and (62.2±5.6) d, respectively, and the differences among the 3 groups were statistically significant ( F=14.096, P=0.001). Compared with the group A, patients in the groups B and C had a prolonged time to stroke recurrence within 90 days ( Z=-3.108, P=0.002; Z=-2.871, P=0.004), whereas the difference in the time to stroke recurrence within 90 days between patients in the groups B and C was not statistically significant ( Z=0.397, P=0.692). The time to stroke recurrence within 90 days was positively correlated with the level of LDL-C on day 90 ( β=0.850, P=0.031). Ten patients (6.0%) in the group A developed hepatic insufficiency, 1 patient (0.6%) in the group B, and 9 patients (5.4%) in the group C. The differences among the 3 groups were statistically significant (χ 2=7.622, P=0.022); and the difference between the group B and group C was statistically significant ( P=0.011). The differences of secondary safety endpoints, death due to stroke within 90 days [1 case (0.6%) in the group A, 0 case (0) in the group B, and 1 case (0.6%) in the group C], fatal and nonfatal myocardial infarction within 90 days [3 cases (1.8%) in the group A, 1 case (0.6%) in the group B, and 1 case (0.6%) in the group C], were not statistically significant among the 3 groups (all P>0.05). Conclusions:In patients with acute ischemic stroke, PCSK9 inhibitor combined with rosuvastatin (both medium and high doses) significantly reduced LDL-C levels compared with baseline, and at the same time prolonged the time to stroke recurrence, reduced adverse effects such as hepatic insufficiency, and had a high degree of safety. PCSK9 inhibitor combined with medium-dose rosuvastatin had a better effect.
