Objective To assess the clinical value of a novel surgical technique—Tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device in the resection of anterior mediastinal masses. Methods Patients who underwent tubeless subxiphoid uniportal video-assisted thoracoscopic surgery via balance-shaped sternal elevation device in anterior mediastinal masses process at the Department of Thoracic Surgery, West China Hospital, Sichuan University from March to April 2025 were included, and their clinical data were analyzed. Results A total of 4 patients were included, with 2 males and 2 females, aged 58-75 years. The diameter of the tumor was 2.5-3.0 cm. The operation time was 60.0-150.0 min, intraoperative blood loss was 5-10 mL, pain score on the 3rd day after surgery was 0 points, and postoperative hospital stay was 2-3 days. All patients achieved complete resection of the masses and thymus without perioperative complications. Conclusion The tubeless subxiphoid uniportal video-assisted thoracoscopic surgery with percutaneous suspension technique via balance-shaped sternal elevation device technique optimizes surgical visualization and instrument maneuverability while avoiding complications related to conventional anesthesia and tubing, thereby markedly enhancing the minimally invasive profile of anterior mediastinal masses resections. In addition to maintaining procedural safety, this approach effectively reduces postoperative pain and accelerates patient recovery, highlighting its potential for widespread clinical adoption.

Objective This study aims to compare the efficacy of video stylets and video laryngoscopes in facilitating nasotracheal intubation during oral surgery.Methods A total of 80 patients,aged between 18 and 70 years old,with ASA grade Ⅰ or Ⅱ,scheduled for elective oral surgery under general anesthesia,were randomly assigned to either the video stylet group(Group N)or the video laryngoscope group(Group C),with 40 patients in each group.In Group N,a video stylet was used to shape the tracheal tube at a 90-degree angle,with the shaping position being the vertical distance from the Adam's apple to the nostril.The tube was inserted from the nasal cavity into the throat under direct visualization,and positioned behind the glottis.In Group C,the tube was initially blindly inserted into the nasal cavity without a core.Upon reaching the throat,a video laryngoscope was employed to lift the epiglottis and expose the glottis from the mouth.The tube was then inserted with the aid of intubation forceps or cuff inflation.The primary outcome measure was the intubation time.Additional measures included the time taken for nasal passage,glottis exposure,and the number of intubation attempts and assistant interventions required.Vital signs,including MAP and HR,were recorded at five minutes of quiet rest upon entering the room(T0),during glottis exposure(T1),upon passage of the tube through the glottis(T2),and one minute after the tube entered the trachea(T3).Complications such as epistaxis,oral mucosal bleeding,loose incisors,and postop-erative sore throat were also documented.Results The intubation time and nasal passage time in Group N were significantly shorter than those in Group C(P<0.05).The number of cuff inflations and intubation forceps assisted cases in Group N was significantly lower than in Group C(P<0.05).There were no significant differences between the two groups in terms of glottis exposure time,first successful intubation times,C-L glottis classification,and mandibular lift-assisted intubation(P>0.05).The increase in MAP and HR in Group N at T1 and T2 was signifi-cantly less than in Group C(P<0.05).The number of cases with mild epistaxis in Group N was significantly lower than in Group C(P<0.05).Similarly,the number of cases with loose incisors and oral mucosal bleeding in Group N was significantly less than in Group C(P<0.05).Conclusion Compared to the video laryngoscope,the video stylet-guided nasotracheal intubation results in a shorter intubation time,less damage to the oronasopharynx,eliminates the need for intubation forceps,and reduces the patient's stress and vascular stress response during intubation.

Objective:To observe the protective effects of Zhiganqing Prescription on the liver of C57BL/6J non-alcoholic fatty liver disease (NAFLD) mice induced by high fat diet and its effects on PI3K/Akt/FoxO1 signaling pathway, insulin resistance (IR) and gluconogenesis.Methods:A total of 48 8-week-old male C57BL/6J mice were divided into control group ( n=8) and modeling group ( n=40) according to random number table method. The control group was fed with ordinary diet, and the model group was fed with high-fat diet. The NAFLD model was established after 8 weeks of feeding. The modeling group was divided into model group, Pioglitazone group, Zhiganqing Prescription low-, medium-, and high-dosage group ( n=8 in each group) according to random number table method, and drug intervention lasted for 8 weeks. The body mass of mice was measured regularly during administration. Fasting blood glucose (FBG) levels were measured at 0 and 8 weeks of administration, and oral glucose tolerance tests (OGTT) were conducted. After the experiment, serum levels of GPT, GOT, TC, TG, LDL-C, HDL-C, FINS and C-P were detected and HOMA-IR was calculated. The pathological morphology of liver was observed by HE and PAS staining. The expression levels of PI3K and p-Akt were detected by IHC staining. The protein expression levels of PI3K, Akt, p-Akt, FoxO1, p-FoxO1, G6PC and PCK1 were detected by Western blot. Results:Compared with model group, the body weight of mice in each administration group decreased at 4, 6 and 8 weeks ( P<0.05 or P<0.01). At the 8th week of administration, the levels of FBG and OGTT AUC in each administration group decreased ( P<0.05 or P<0.01), the levels of GPT, TC, TG and LDL-C decreased ( P<0.01), and the GOT levels in Zhiganqing Prescription medium- and high-dosage groups decreased ( P<0.01). The HDL-C level in Zhiganqing Prescription medium-dosage group decreased ( P<0.05 or P<0.01), and the HOMA-IR level in Zhiganqing Prescription low- and medium-dosage groups decreased ( P<0.05 or P<0.01). The levels of FINS and C-P in each administration group increased ( P<0.05 or P<0.01), and the expressions of PI3K protein and p-Akt/Akt, p-FoxO1 /FoxO1 protein in liver tissues increased ( P<0.05 or P<0.01). The protein expressions of G6PC and PCK1 decreased ( P<0.05 or P<0.01). Conclusion:Zhiganqing Prescription can effectively control the body mass, blood glucose, liver function and blood lipids of NAFLD mice, improve IR and gluconeogenesis, the mechanism of which may be related to the activation of PI3K/Akt/FoxO1 signaling pathway.

Thalamocortical circuitry has a substantial impact on emotion and cognition.Previous studies have demonstrated alterations in thalamocortical functional connectivity(FC),characterized by region-dependent hypo-or hyper-connectivity,among individuals with major depressive disorder(MDD).However,the dynamical reconfiguration of the thalamocortical system over time and potential abnormalities in dynamic thalamocortical connectivity associated with MDD remain unclear.Hence,we analyzed dynamic FC(dFC)between ten thalamic subregions and seven cortical subnetworks from resting-state functional magnetic resonance images of 48 patients with MDD and 57 healthy controls(HCs)to investigate time-varying changes in thalamocortical FC in patients with MDD.Moreover,dynamic laterality analysis was conducted to examine the changes in functional lateralization of the thalamocortical system over time.Correlations between the dynamic measures of thalamocortical FC and clinical assessment were also calculated.We identified four dynamic states of thalamocortical circuitry wherein patients with MDD exhibited decreased fractional time and reduced transitions within a negative connectivity state that showed strong correlations with primary cortical networks,compared with the HCs.In addition,MDD patients also exhibited increased fluctuations in functional laterality in the thalamocortical system across the scan duration.The thalamo-subnetwork analysis unveiled abnormal dFC variability involving higher-order cortical networks in the MDD cohort.Significant correlations were found between increased dFC variability with dorsal attention and default mode networks and the severity of symptoms.Our study comprehensively investigated the pattern of alteration of the thalamocortical dFC in MDD patients.The heterogeneous alterations of dFC between the thalamus and both primary and higher-order cortical networks may help characterize the deficits of sensory and cognitive processing in MDD.

Objective To explore the clinical characteristics of patients with drug-induced liver injury(DILI),so as to provide references for its diagnosis and treatment.Methods The clinical data of inpatients diagnosed as DILI in The Third Affiliated Hospital of Naval Medical University(Second Military Medical University),from Jan.2017 to Dec.2021 were retrospectively analyzed,including basic information,underlying diseases,drug use history,clinical manifestations,laboratory indexes,severity and prognosis of DILI.Results Among 145 patients with DILI,112 cases(77.24％)were hepatocellular type,25 cases(17.24％)were cholestatic type,and 8 cases(5.52％)were mixed type.The types of drugs causing DILI mainly included traditional Chinese medicine,proprietary Chinese medicine and anti-infective drugs,and the proportions were 48.72％(76/156),16.03％(25/156),and 10.26％(16/156),respectively.The common clinical manifestations of DILI patients were jaundice(76.55％),poor appetite(52.41％),and fatigue(49.66％).The levels of alanine transaminase(ALT),aspartate transaminase,alkaline phosphatase(ALP),total bilirubin(TBil),γ-glutamyl transferase and albumin(ALB),as well as the length of hospital stay and severity distribution were significantly different among different types of liver injury(all P＜0.05).The levels of ALT and ALB in the good prognosis group were significantly higher than those in the poor prognosis group,while the levels of TBil and international normalized ratio in the good prognosis group were significantly lower than those in the poor prognosis group(all P＜0.05).Multivariate analysis showed that INR was an independent predictor of the prognosis of DILI(P＜0.05).Conclusion Serum biochemistry indicators can help to identify the clinical classification and prognosis of DILI.Traditional Chinese medicine,proprietary Chinese medicine and other drugs can cause DILI.Medical staff should pay attention to it and strengthen public health education.

Yigongsan， derived from QIAN Yi’s Key to Therapeutics of Children’s Diseases in the Song Dynasty， is a classic pediatric prescription that is included in the Catalogue of Ancient Classic Prescriptions （the Second Batch of Pediatrics） released by the National Administration of Traditional Chinese Medicine in 2022. This paper verifies and analyzes the historical origin， composition， dosage， processing， decoction method and efficacy of Yigongsan by systematically combing ancient books and modern documents. As a result， Yigongsan is composed of five herbs： Panax ginseng， Poria cocos， Atractylodes macrocephala， Citrus reticulata and Glycyrrhiza uralensis， of which P. cocos should be peeled， A. macrocephala is fried with soil， G. uralensis is roasted with honey while P. ginseng and C. reticulata are raw products. According to the dosage of ancient and modern times， each medicinal herb must be ground into fine powder， 1.6 g for each， added with 300 mL of water， 5 pieces of Zingiber officinale， and 2 Ziziphus jujuba， decocted together to 210 mL， and taken before meals. In ancient books， Yigongsan is used to treat vomiting， diarrhea， spleen and stomach deficiency， chest and abdominal distension， and lack of appetite， etc. Modern research showed that Yigongsan could also be used in the diseases of immune system， respiratory system， blood system， etc.， involving infantile anorexia， asthma， anemia， tumors and so on.

Objective:To construct a column-line diagram diagnostic model based on serum and joint fluid inflammatory markers for the diagnosis of periprosthetic joint infections (PJI) after joint arthroplasty and to validate its predictive ability.Methods:The clinical data of 181 patients diagnosed with PJI or aseptic loosening in the Department of Orthopedics of the First Affiliated Hospital of Chongqing Medical University from January 2015 to June 2020 were retrospectively collected as a modeling group. The best indicators for diagnosing PJI were screened by lasso regression, single-factor and multifactor analysis. By comprehensively considering the weights and intrinsic connections of the indicators, a column-line diagram diagnostic model was constructed and used to develop a clinical decision support system (CDSS). Prospectively, the clinical data of patients diagnosed with PJI or aseptic loosening in the Department of Orthopedics of the First Hospital of Chongqing Medical University from July 2020 to December 2022 were collected as a validation group, and the diagnostic performance of the column-line diagram model was externally validated by methods such as receiver operating characteristic curve (ROC).Results:There were 85 cases of PJI in the 181 cases modeling group and 23 cases of PJI in the 49 cases validation group. Among the 27 potential factors analyzed by lasso regression analysis, body mass index (BMI), blood tests including platelet (PLT), absolute lymphocyte value, interferon γ (IFN-γ), ESR, IL-6, C-reactive protein, D-dimer, and joint fluid tests including C-reactive protein, IL-1, IL-4, IL-6, percentage of multinucleated neutrophils (PMN%), and CD64 may be potential indicators for the diagnosis of PJI. Univariate found significant differences between hematologic tests including sedimentation, C-reactive protein, IL-6, D-dimer and joint fluid tests including C-reactive protein, joint fluid CD64 index, C-reactive protein, IL-1, IL-4, IL-6, PMN%( P<0.05). Further multifactorial regression analysis screened serum IL-6, D-dimer, joint fluid CD64 index, C-reactive protein, IL-1, IL-4, IL-6, and percentage of multinucleated neutrophils, and based on that, the column-line graph model and CDSS system were constructed. The area under the ROC in the validation group was 0.978, and the AUC in the internal validation was 0.995; the C-index of the calibration curve was 99.50%, and the C-index of the internal validation was 99.53%, suggesting that the column-line diagram model has a good predictive ability. Conclusions:The column-line diagram for diagnosing PJI based on multiple diagnostic indicators showed good diagnostic performance. The CDSS system constructed by column-line diagrams could assist clinicians in diagnosing PJI and making reasonable strategies in time.

The development of inflammatory bowel diseases (IBD) is associated with genetics, environment, immune abnormalities, and intestinal flora, including ulcerative colitis (UC) and Crohn′s disease (CD). Hypoxia-inducible factor-1α (HIF-1α) is a transcription factor that promotes the expression of multiple genes in response to the hypoxic environment, and its roles in regulating intestinal barrier function, intestinal metabolism, and inflammatory and immune responses are research hotspots. This article reviews the role of HIF-1α in IBD by analyzing the relationships between HIF-1α and intestinal epithelial barrier and inflammatory response to provide new ideas for the clinical treatment of IBD.
