Objective To introduce an innovative technique, the "balance-shaped sternal elevation device" and its application in the subxiphoid uniportal video-assisted thoracoscopic surgery (VATS) for anterior mediastinal masses resection. Methods Patients who underwent single-port thoracoscopic assisted anterior mediastinal tumor resection through the xiphoid process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from May to June 2024 were included, and their clinical data were analyzed. Results A total of 7 patients were included, with 3 males and 4 females, aged 28-72 years. The diameter of the tumor was 1.9-17.0 cm. The operation time was 62-308 min, intraoperative blood loss was 5-100 mL, postoperative chest drainage tube retention time was 0-9 days, pain score on the 7th day after surgery was 0-2 points, and postoperative hospital stay was 3-12 days. All patients underwent successful and complete resection of the masses and thymus, with favorable postoperative recovery. Conclusion The "balance-shaped sternal elevation device" effectively expands the retrosternal space, providing surgeons with satisfactory surgical views and operating space. This technique significantly enhances the efficacy and safety of minimally invasive surgery for anterior mediastinal masses, reduces trauma and postoperative pain, and accelerates patient recovery, demonstrating important clinical significance and application value.

Objective To compare the efficacy and safety of video-assisted thoracoscopic surgery (VATS) thymectomy for the treatment of thymoma through subxiphoid uniportal approach using double sternum retractors, and subxiphoid and subcostal arch approach. Methods We retrospectively analyzed the clinical data of the patients diagnosed with thymoma who underwent VATS thymectomy from June 2023 to June 2024 in West China Hospital. Patients were categorized based on the surgical approach into two groups: a subxiphoid uniportal VATS thymectomy (SUVT) group and a subxiphoid and subcostal arch VATS thymectomy (SASAT) group. Comparisons were made between the two groups regarding surgical duration, intraoperative blood loss, postoperative drainage, thymoma size and location, and postoperative pain assessed using the visual analogue scale (VAS). Results The SUVT group consisted of 20 patients, including 11 males and 9 females, with an average age of (51.5±14.3) years. The SASAT group comprised 40 patients, including 26 males and 14 females, with an average age of (50.0±13.0) years. Compared to the SASAT group, the SUVT group had significantly larger thymomas [ (5.9±2.7) cm vs. (4.2±2.1) cm, P=0.010] and a higher proportion of neoplasms located in the superior mediastinum (30.0% vs. 2.5%, P=0.007). Additionally, the VAS pain scores on postoperative days 3, 7, and 30 were significantly lower in the SUVT group compared to the SASAT group (P<0.05). There were no statistical differences between the two groups in demographic characteristics, operative time, intraoperative blood loss, duration and volume of postoperative drainage, length of postoperative hospital stay, or the VAS pain score on the first postoperative day. Conclusion SUVT using double sternum retractors significantly reduces postoperative pain and provides superior efficacy in the resection of larger thymomas or those situated in the superior mediastinum.

OBJECTIVE To investigate the effects of total glucosides of paeony （TGP） on enhancing efficacy and reducing toxicity of Tripterygium wilfordii polyglycoside （TWP） in the treatment of eczema. METHODS Totally 50 SD male rats were collected to establish eczema model by sensitizing with 2，4-dinitrofluorobenzene-acetone olive oil solution （volume ratio was 4∶1） on the abdominal area and provoking on the back and ear. Model rats were randomly divided into model group， loratadine group （0.9 mg/kg）， TWP group （9.45 mg/kg）， TGP group （162 mg/kg） and compatibility group （TWP 9.45 mg/kg+TGP 162 mg/kg）， with 10 rats in each group. Other 10 rats were collected to set as normal group. Three days after the first sensitization， administration groups were given relevant medicine intragastrically， and normal group and model group were given constant volume of 0.1% CMC-Na solution intragastrically， once a day， for consecutive 21 d. Twenty-four hours later after the final administration， the general condition of rats in each group was observed， and the eczema area and severity index （EASI） were scored； ear swelling degree of rats was measured， and the skinhistomorphology observation and pathological score were performed； protein expressions of p38 mitogen-activated 13938427612@126.com protein kinase （p38 MAPK）， phosphorylated p38 MAPK （p- MAPK） and phosphorylation level of p38 MAPK in rat skin tissue were detected； the levels of inflammatory indexes （interleukin-4， interferon- γ）， liver and kidney function indexes [glutamic-pyruvic transaminase （GPT）， glutamic-oxaloacetic transaminase （GOT）， serum creatinine （SCr） and blood urea nitrogen （BUN）] and oxidant stress indexes [total superoxide dismutase （T-SOD） and malondialdehyde （MDA）] were measured. RESULTS Compared with normal group， EASI score， ear swelling degree， pathological score， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation level of p38 MAPK， the levels of inflammatory indexes and BUN were all increased significantly in model group （P＜0.05）. Compared with model group， EASI scores， ear swelling degree， pathological scores， protein expressions of p38 MAPK and p-p38 MAPK， phosphorylation levels of p38 MAPK and levels of inflammatory indexes were all improved significantly in administration groups （P＜0.05）. The levels of GPT， GOT， SCr and BUN were increased significantly in TWP group， while the serum levels of GOT and SCr in TGP group and serum level of SCr in loratadine group were all decreased significantly （P＜0.05）. The levels of T-SOD in liver and kidney tissue were all decreased significantly in TWP group and compatibility group， while the levels of MDA were increased significantly （P＜0.05）. The compatibility group showed more obvious effect in improving the ear swelling degree， pathological score， p38 MAPK expression and its phosphorylation level and levels of inflammatory indexes， and could reverse the abnormality of liver and kidney indexes caused by TWP （P＜0.05）. CONCLUSIONS The combination of TGP and TWP has the effects of anti-inflammatory， synergistic and hepatorenal detoxification in eczema model rats. Its mechanism may be associated with down-regulating the expression of serum proinflammatory indexes and inhibiting the activation of p38 MAPK pathway.

Objective: To probe the feasibility of decitabine (DAC) combined with micro-transplantation as consolidation treatment for older patients with acute myeloid leukemia (AML). Methods: Between November 2012 and September 2015, 37 consecutive patients with AML ≥60 years of age were analyzed. Of them, 19 patients received consolidation therapy with DAC followed by micro-transplantation (microtransplant group). Another 18 ones (chemo group) were treated with DAC plus priming regimen as consolidation chemotherapy in the same period. Results: There were no significant differences in terms of age, WBC count, and disease status of onset between the microtransplant and chemo groups (P>0.05). The two regimens were well tolerated. There was no difference of CTC grade 3-4 nonhematologic toxicities between the microtransplant and chemo groups (36.8% vs 27.8%, χ²=0.347, P=0.728). The median recovery durations for neutrophil and platelet in the microtransplant group were similar to those in the chemo group (12 vs 13 days, z=1.599, P=0.110; 14 vs 12 days, z=-1.314, P=0.189, respectively). No graft-versus-host disease was observed in the microtransplant group. The 2-year leukemia-free survival and overall survival were better in microtransplant group (50.7% and 54.9%, respectively) than in chemo group (24.3% and 30.0%, respectively) (P=0.047 and P=0.071, respectively). Conclusion DAC combined with micro-transplantation as a consolidation regimen may be a safe and promising option for older patients with AML.
