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.

ObjectiveThis study aims to identify cuproptosis-related gene biomarkers in Alzheimer's disease(AD) using bioinformatics and machine learning methods, validate them at the clinical specimen level, and predict potential traditional Chinese medicine(TCM). MethodsDifferentially expressed genes in the AD group and normal group were obtained using the Gene Expression Omnibus (GEO) database, and intersections were taken with reported cuproptosis-related genes to obtain differentially expressed cuproptosis-related genes. Machine learning methods were applied to identify core differential genes of cuproptosis in AD. Peripheral blood's single nucleated cells from clinical AD patients were collected, and the relative gene expression was clinically verified by real-time polymerase chain reaction(Real-time PCR). Potential TCM regulating cuproptosis for AD were predicted by COREMINE database. ResultsA total of 12 cuproptosis-related genes were obtained, mainly involved in pathways of tricarboxylic acid cycle, 2-oxocarboxylic acid metabolism, and carbon metabolism. Five core cuproptosis-related genes, dihydrolipoamide dehydrogenase (DLD), glutaminase (GLS), pyruvate dehydrogenase E1 subunit beta (PDHB), full name nuclear factor (erythroid-derived 2)-related factor 2 (NFE2L2), and dihydrolipoamide branched-chain transacylase E2 (DBT) were finally screened using four machine methods. Thirty cases each of normal and AD patients were collected clinically. Compared with those in the normal group, minimum mental state examination (MMSE) and Montreal cognitive assessment (MoCA) were significantly decreased in the AD group (P<0.01), Homocysteine(Hcy), interleukin(IL)-6, C-reactive protein(CRP) , and β amyloid protein(Aβ) indexes were significantly increased (P<0.01), and malondialdehyde(MDA) indexes were decreased (P<0.05). Superoxide dismutase(SOD) levels were significantly decreased (P<0.01). The mRNA relative expressions of NFE2L2 and DBT were up-regulated (P<0.05), and those of DLD, GLS, and PDHB were significantly down-regulated (P<0.01). The TCM regulating cuproptosis-related genes for the treatment of AD were mainly based on the four Qi such as warmth, calmness, and cold, and the five flavors including bitterness, sweetness, and pungency, and it was attributed to the meridians of the liver, spleen, stomach, and kidney, with the efficacy of tonifying Qi, activating blood, eliminating phlegm, and resoling dampness. ConclusionDLD, GLS, NFE2L2, PDHB, and DBT can be used as novel diagnostic molecular markers for AD cuproptosis-related genes, and the corresponding potential therapeutic TCM can provide new ideas for the treatment of AD by TCM.

OBJECTIVES:
To explore the mechanism of Gandou Fumu Decoction (GDFMD) for improving Wilson's disease (WD) in tx-J mice.
METHODS:
With 6 syngeneic wild-type mice as the control group, 30 tx-J mice were randomized into WD model group, low-, medium- and high-dose GDFMD treatment groups, and Fer-1 treatment group. Saline (in control and model groups) and GDFMD (3.48, 6.96 or 13.92 g/kg) were administered by gavage, and Fer-1 was injected intraperitoneally once daily for 14 days. Oil red and HE staining were used to observe lipid deposition and pathological conditions in the liver tissue; ALT, AST, albumin, AKP levels were determined to assess liver function of the mice. Western blotting and RT-qPCR were used to detect hepatic protein and mRNA expressions of GPX4, ACSL4, ALOX15, FTH1, FLT, TFR1, FAS, SCD1, and ACOX1, and Fe2+, MDA, ROS, SOD, GSH and 4-HNE levels were analyzed to assess oxidative stress.
RESULTS:
The mouse models of WD showed obvious fatty degeneration in the liver tissue significantly increased serum levels of ALT, AST and AKP, decreased albumin level, increased Fe2+, MDA, ROS, 4-HNE levels, decreased SOD and GSH levels (P<0.05), lowered protein expressions of ACOX1, GPX4, FTH1, FLT, FAS, and SCD1, and increased protein contents of TFR1, ACSL4 and ALOX15 in the liver. Treatment with GDFMD and Fer-1 improved liver histopathology and liver function of the mouse models, decreased the levels of Fe2+, MDA and ROS, increased SOD and GSH levels, and reversed the changes in hepatic protein expressions.
CONCLUSIONS
GDFMD improves liver steatosis in mouse models of WD possibly by inhibiting hepatocyte ferroptosis through the GPX4/ACSL4/ALOX15 signaling pathway.

Objective:To investigate the clinical efficacy of butylphthalide combined with hyperbaric oxygen therapy on post-stroke cognitive impairment in patients with acute ischemic stroke.Methods:A total of 90 patients with post-stroke cognitive impairment who were hospitalized within 72 hours of onset in Suining County People's Hospital from December 2019 to November 2020 were included in this study. They were randomly divided into a control group and an observation group ( n = 45/group). The control group was given conventional treatment and the observation group was given butylphthalide combined with hyperbaric oxygen therapy in addition to conventional treatment. The National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score were compared between the two groups before and after treatment. Results:Before treatment, there were no significant differences in the National Institutes of Health Stroke Scale score, Montreal Cognitive Assessment score, and Activities of Daily Living score between the two groups (all P > 0.05). At 14 days and 1 month after surgery, the National Institutes of Health Stroke Scale scores in the observation group were (4.02 ± 2.18) points and (3.21 ± 2.03) points, which were significantly lower than (5.21 ± 2.24) points and (4.62 ± 2.68) points in the control group ( t =2.55, 2.81, both P < 0.05). At 1 and 3 months after treatment, the Montreal Cognitive Assessment score in the observation group were (19.79 ± 5.67) points and (23.69 ± 2.67) points, which were significantly higher than (16.88 ± 5.12) points and (19.74 ± 2.29) points in the control group ( t = 2.56, 7.53, both P < 0.05). At 1 and 3 months after treatment, Activities of Daily Living scores in the observation group were (54.85 ± 5.69) points and (74.38 ± 4.98) points, which were significantly higher than (46.78 ± 6.24) points and (63.21 ± 5.24) points in the control group ( t = 6.41, 9.76, both P < 0.05). Conclusion:Butylphthalide combined with hyperbaric oxygen therapy for the treatment of post-stroke cognitive impairment in patients with acute ischemic stroke can alleviate neurologic deficits, and improve cognitive function and the ability of daily life.

Rheumatic diseases, a typical kind of autoimmune disease, are often treated with glucocorticoids, immunosuppressants, biological agents, and small-molecule targeted drugs, which often leads to immune dysfunction in patients and increases the risk of activation of latent tuberculosis infection. To regulate the screening, diagnosis, and prophylactic treatment of latent tuberculosis infection in patients with rheumatic diseases, reduce the risk of developing active tuberculosis and improve the prognosis, Peking University Shenzhen Hospital, Shenzhen Third People′s Hospital and Peking Union Medical College Hospital jointly organized domestic experts in the field of rheumatology and tuberculosis to establish the expert consensus on the diagnosis and treatment of latent tuberculosis infection in patients with rheumatic diseases. This consensus focuses on epidemiology, the importance of screening, screening methods, and prophylactic anti-tuberculosis treatment strategies for latent tuberculosis infection combined with rheumatic diseases.

ObjectiveTo explore the characteristics of eye collaterals of patients with hepatic Wilson's disease (WD) and intervention effect of Gandouling (GDL) based on digital diagnosis information on eyes, in order to provide references for the clinical efficacy of GDL in the treatment of patients with hepatic WD. MethodEighty-two patients with hepatic WD (WD group) and 68 healthy volunteers (normal control group, NC) were enrolled. Eye images of all subjects were collected by the ophthalmoscope, followed by digital extraction of eye collateral characteristics. Differences in main eye collateral characteristics between the WD group and the NC group were analyzed. Pearson correlation test was used to analyze the eye collateral characteristics, serological indexes of liver damage [alanine aminotransferase (ALT),aspartate transaminase (AST),and albumin (ALB)], and Child-Pugh score in patients with hepatic WD. The 82 patients with hepatic WD were divided into a treatment group (42 cases) and a control group (40 cases). All patients were treated with sodium 2,3-dimercapto-1-propane sulfonate (DMPS), while those in the treatment group received additional GDL Tablets. One course of treatment contained eight days, and the treatment lasted six courses. The effects of GDL intervention on the levels of ALT,AST, and ALB,as well as the eye collateral characteristics score and Child-Pugh score were evaluated. Result① Compared with the NC group,the WD group had higher scores of "Qiu" (P<0.05) and "Xuemai" (P<0.05),which are the characteristics of eye collaterals. ② The levels of ALT and AST, and Child-Pugh score in patients with hepatic WD were positively correlated with the scores of "Qiu" and "vessel",while the ALB level was negatively correlated with the "bulge" and "Xuemai" scores. ③ Compared with the conditions before treatment,the serum ALT and AST levels,Child-Pugh score,and the "Qiu" and " Xuemai " scores of the two groups were reduced (P<0.01),and the ALB levels were increased (P<0.01). ④ Compared with the control group after treatment,the treatment group showed improved levels of ALT and ALB and the scores of "Qiu" and "Xuemai" (P<0.05)and better Child-Pugh score (P<0.01). There was no significant difference in AST between the two groups. ConclusionCompared with healthy people,hepatic WD patients showed higher scores of "Qiu" and "Xuemai", indicating that patients with hepatic WD were mainly characterized by dampness and heat,and the scores of "Qiu" and "Xuemai" were positively correlated with the severity of liver damage. Meanwhile,copper-expelling therapy combined with GDL can significantly improve the liver function of WD patients and improve the clinical efficacy.

Objective:To investigate the application value of triangular modal construed for planning approach of laparoscopic local resection of liver tumors located in superior part of central liver lobe.Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 10 patients who underwent local laparoscopic resection of liver tumors located in superior part of central liver lobe at the Affiliated Hospital of Qingdao University from January to June 2020 were collected. There were 6 males and 4 females, aged from 41 to 63 years, with a median age of 54 years. Preoperative triangular model was constructed for all patients to plan approach of laparoscopic local resection of liver tumors located in superior part of central liver lobe. Observation indicators: (1) preoperative general situations of patients; (2) surgical situations; (3) follow-up. Follow-up was conducted by outpatient examination or telephone interview to detect tumor recurrence and survival of patients up to February 2021. Measurement data with normal distribution were expressed as Mean± SD. Count data were expressed was absolute numbers. Results:(1) Preoperative general situations of patients: hepatocellular carcinoma was found in 7 cases, inthahepatic cholangiocarcinoma was found in 2 cases and ovarian cancer with liver metastasis was found in 1 case. Three cases had tumors located in S4a segment, 2 cases had tumors located in ventral subsegment of S8 segment, 2 cases had tumors located in dorsal subsegment of S8 segment, and 3 cases had tumors across the ventral segment of S4a+S8. The diameter of tumors was (3.4±1.0)cm. (2) Surgical situation: all the 10 patients underwent R 0 resection successfully, with no intraoperative blood transfusion or conversion to open surgery. The operation time of 10 patients was (149±59)minutes, the volume of intraoperative blood loss was (294±163)mL, the minimum surgical margin of specimen was (1.1±0.2)cm. The alanine aminotransferase was (324±151)U/L on the postoperative first day, the aspartic aminotransferase was (401±113)U/L on the postoperative first day, and the duration of postoperative hospital stay was (9±4)days. No bile leakage, hemorr-hage, reoperation or other complications occurred in all patients. (3) Follow-up: 10 patients were followed up for 7?13 months, with a median follow-up time of 11 months. All patients had no margin recurrence or distant metastasis. Conclusion:It is safe and feasible to construct triangular modal for planning approach of local laparoscopic resection of liver tumors located in superior part of central liver lobe.

Objective:To investigate the risk factors for recurrence of Graves′ disease after withdrawal of antithyroid drugs (ATD).Methods:This prospective study recruited 285 patients with newly onset Graves′ disease taking ATD from 2012 to 2018 at Department of Endocrinology, Affiliated Hospital of Integrated Traditional Chinese and Western Medicine. A total of 121 patients who completed follow-up were enrolled and were divided into relapse and remission group according to whether hyperthyroidism reoccurred within 2 years after ATD with drawal. Demographics, clinical manifestations, thyroid serological characteristics, and thyroid color doppler ultrasound at baseline and withdrawal were compared between the two groups. Cox regression analysis was used to analyze the correlation between above factors and recurrence of Graves′ disease.Results:Sixty-five patients relapsed within 2 years after drug withdrawal. Patients with early recurrence were characterized by Graves′ disease genetic history and high baseline thyrotrophin receptor antibody (TRAb) levels. Family history, higher serum FT 3(≥18.1 pmol/L), FT 4(≥49.8 pmol/L), and TRAb(≥16.1 mIU/mL) levels, larger goiter(Ⅱ-Ⅲ) and thyroid volume(≥28.6 cm 3), higher peak velocity of superior thyroid artery (STA-PV; ≥0.6 m/s) before treatment, and higher TRAb(≥0.8 mIU/mL) level after ATD withdraw were risk factors for Graves′ disease recurrence. Higher 25-hydroxy vitamin D(≥14.7 ng/mL) level at baseline, as well as high level of TSH(1.4 μIU/mL) at withdrawal may reduce the risk of relapse. Conclusions:Family history of Graves′ disease, clinical manifestations, thyroid serological indicators and imaging characteristics of severe Graves′ disease before treatment all increased the risk of Graves′ disease recurrence. Patients with aforementioned factors should be actively evaluated in order to choose treatment modalities reasonably. We recommended to maintain lower TRAb titer within normal reference range and TSH level between 1.4 μIU/mL and upper limits of normal reference range at ATD withdrawal to reduce the recurrence rate of Graves′ disease.
