OBJECTIVE: To investigate the effectiveness of endoscopic-assisted median nerve decompression with one-stage extensor indicis proprius (EIP) tendon transfer for reconstruction of thumb abduction in patients with severe carpal tunnel syndrome (CTS). METHODS: The clinical data of 12 patients with severe CTS who met the selection criteria between December 2019 and December 2024 were retrospectively analyzed. There were 2 males and 10 females with an average age of 55.4 years ranging from 35 to 67 years. The symptom duration of CTS was 12-120 months (mean, 48.7 months) and the thenar muscle atrophy duration was 6-48 months (mean, 13.4 months). The median nerve was released with the help of endoscope, and the EIP tendon was transferred to reconstruct the abduction function of the thumb. The operation time and complications were recorded. Two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, and pinch force of the thumb were measured and compared before operation and at last follow-up, and the effectiveness was evaluated by Kapandji score and Disabilities of the Arm, Shoulder and Hand (DASH) score. The satisfaction of the operation was evaluated at last follow-up. RESULTS: All surgeries were successfully completed with a mean operation time of 54 minutes (range, 45-68 minutes). All patients were followed up 6-50 months, with an average of 15.3 months. There was no complications such as wound infection, scar pain of wrist, or tendon rupture of transposition, and there were 3 cases of mild limitation of finger extension in the donor site of index finger. At last follow-up, two-point discrimination, palmar abduction angle of the thumb, radial abduction angle of the thumb, Kapandji score, and DASH score were significantly better than those before operation ( P<0.05), but there was no significant difference in thumb pinch force between pre- and post-operation ( P>0.05). The evaluation of surgical satisfaction showed that 7 cases were very satisfied and 5 cases were satisfied. CONCLUSION The combination of endoscopic-assisted median nerve decompression and one-stage EIP tendon transfer effectively improves hand function and quality of life in patients with severe CTS by restoring thumb abduction and alleviating neurological symptoms.

ObjectiveTo investigate the therapeutic effect of Dayuanyin on acute lung injury induced by H1N1 infection and decipher the potential mechanism. MethodThe constituents in Dayuanyin were analyzed by ultra-high performance liquid chromatography-quadrupole-exactive orbitrap mass spectrometry （UHPLC-Q-Exactive Orbitrap MS）. Forty-eight female BALB/c mice were randomized into normal， model， oseltamivir （19.5 mg·kg^-1）， and low-， medium-， and high-dose （2.73， 5.46， 10.92 g·kg^-1） Dayuanyin groups. The normal and model groups were administrated with deionized water by gavage， and the other groups were administrated with the corresponding drugs by gavage. On day 3 of drug administration， the normal group received nasal inhalation of normal saline， and the other groups were inoculated intranasally with A/RP/8/34 （H1N1） for the modeling of influenza virus infection. Mice were administrated with drugs continuously for 7 days and weighed daily. Sampling was performed 12 h after the last administration， and the lung tissue was weighed to calculate the lung index. Hematoxylin-eosin staining was performed to observe the pathological and morphological changes of the lung tissue and bronchi. The cytometric bead array （CBA） was used to measure the serum levels of interferon-gamma （IFN-γ）， C-X-C motif ligand 1 （CXCL1）， tumor necrosis factor-alpha （TNF-α）， chemokine ligand 2 （CCL2）， interleukin-12p70 （IL-12p70）， chemokine ligand 5 （CCL5）， interleukin-1β （IL-1β）， chemokine （C-X-C motif） ligand 10 （CXCL10）， granulocyte-macrophage colony-stimulating factor （GM-CSF）， interleukin-10 （IL-10）， interferon-beta （IFN-β）， interferon-alpha （IFN-α）， and interleukin-6 （IL-6）. According to the results of mass spectrometry and network pharmacology， we analyzed the mechanism of Dayuanyin in treating acute lung injury caused by H1N1. The protein levels of extracellular signal-regulated kinase 1/2 （ERK1/2）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor-kappa B （NF-κB）， and their phosphorylated forms were determined by Western blot. The mRNA levels of myeloid differentiation factor 88 （MyD88）， Toll-like receptor 3 （TLR3）， Toll-like receptor 7 （TLR7）， and Toll-like receptor 8 （TLR8） in the lung tissue were measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultA total of 57 compounds， including paeoniflorin and baicalein， were detected in Dayuanyin. Compared with the normal group， the model group showed decreased body weight （P<0.01）， lung edema and hemorrhage， increased lung index （P<0.01）， and elevated levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. Compared with the model group， Dayuanyin attenuated alveolar wall thickening， capillary congestion， and immune cell infiltration， reduced the alterations in body weight and lung index （P<0.01）， and down-regulated the protein levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. A total of 57 key genes were predicted by network pharmacological analysis， of which the MAPK signaling pathway was the main target signaling pathway. Compared with the normal group， the model group showed up-regulation in the protein levels of phosphorylation （p）-ERK1/2， p-p38 MAPK， and p-NF-κB （P<0.01） and the mRNA levels of TLR7， TLR8， MyD88， and TLR3 （P<0.05， P<0.01）. Compared with the model group， Dayuanyin lowered the phosphorylation levels of ERK1/2， p38 MAPK， and NF-κB p65 in a dose-dependent manner （P<0.01） and down-regulated the mRNA levels of TLR3， TLR7， TLR8， and MyD88 （P<0.01）. ConclusionDayuanyin can prevent and control H1N1 infection-induced acute lung injury by inhibiting the TLR/MAPK/NF-κB signaling pathway.

Objective To understand the reliability of caloric test results through the analysis of the pod shape dia-gram types of caloric test and to provide a more accurate and reliable basis for vestibular system function evaluation.Meth-ods The results of caloric test in 528 patients from July 2021 to May 2022 in vertigo diagnosis and treatment center were analyzed.According to pod pattern and unilateral weakness(UW),the patients were divided into five groups:cold and warm test symmetrical group,left and right side asymmetry group,single value significant abnormal group,bilateral hypo-plasia group and pod morphology unable to be classified group.Unreliable data can be identified by comparing,explaining,and summarizing the results of UW of different groups,so as to reduce the interference of unreliable data to clinical diagno-sis and treatment.Results Cold and warm test symmetric group(n=439)included patients with symmetry of bilateral vestibular function(n=273)and decreased vestibular function of one side(n=166).Left and right symmetrical groups in-eluded pationts with bilateral symmetric vestibular function(n=11)and unilateral reduction(n=13).Single value signifi-cant abnormal group showed cases with unilateral vestibular function reduction(n=25)and bilateral symmetric vestibular function(n=11).Bilateral hypolasion group showed cases with bilateral symmetric vestibular function(n=25)and unilat-eral reduction(n=9).Pod morphology unclassified group(n=5)suggested varions interference factors.Conduson When the function of the peripheral vestibular is symmetrical and normal,we should be alert to the existence of temperature effect,and should consider the inspection of the perfusion apparatus and the calibration of the irrigation temperature.When the function of the peripheral vestibular shows unilateral weakness,repeating the irrigation is recommended when the single value of the caloric test significantly increases or decreases.If there is no change,repeating the irrigation at the same tem-perature in the other ear or even repeating the whole caloric test are recommended.The UW value could not truly reflect the state of peripheral vestibular function when the caoric test produces bilateral weakness.Therefore,water irrigation could be used to make a correct judgment based on the medical history and other auxiliary examinations.It is of great significance to judge the effectiveness of caloric test comprehensively by combining the morphology of pod diagram with UW value.

Objective:To explore the relations of changes in the cognitive function with brain structure network in patients with cerebellar infarction.Methods:Thirty-six patients with cerebellar infarction at the posterior lobe, admitted to our hospital from July 2016 to October 2019, were chosen as cerebellar infarction group; and 30 healthy subjects matched with age, gender, and education level at the same time period were used as control group. Neurocognitive and behavioral tests were performed on both groups to assess the cognitive functions, and MR imaging was performed to obtain diffusion tensor imaging (DTI) data. Deterministic tractography and graph theory were used to obtain the structural brain network and network parameters of all subjects. The differences of clinical data and brain network topological characteristic parameters between the two groups were compared, and the correlation between the subjects' brain structural network characteristic parameters and cognitive function was analyzed.Results:As compared with the control group, patients in the cerebellar infarction group had significantly lower Mini-mental State Examination (MMSE), Montreal Cognitive Scale (MoCA), Rey Auditory Verbal Learning Test (RAVLT), Digit Span Test (DST), Clock Drawing Test (CDT) and Berg Balance Scale (BBS) scores, and significantly longer Trail Making Test (TMT) time-consuming ( P<0.05). As compared with the control group, the cerebellar infarction group showed significantly decreased global efficiency (Eglob) and local efficiency (Eloc) in the brain network, and significantly increased clustering coefficient (Cp) and length of path (Lp, P<0.05). As compared with the control group, the cerebellar infarction group had significantly reduced nodal efficiency in 14 brain regions ( P<0.05), including bilateral median cingulate and paracingulate gyri (DCG), left inferior frontal gyrus-opercular part (IFGoperc), bilateral supplementary motor area (SMA), bilateral precuneus (PCUN), left inferior frontal gyrus-orbital part (ORBinf), left temporal pole-superior temporal gyrus (TPOsup), left temporal pole-middle temporal gyrus(TPOmid), left inferior parietal-supramarginal and angular gyri (IPL), bilateral posterior cingulate gyrus (PCG), left inferior frontal gyrus-triangular part (IFGtriang). MoCA scores were significantly negatively correlated with Lp ( r=-0.388, P=0.019), and were significantly positively correlated with Eglob ( r=0.350, P=0.036), and efficiencies in the right DCG ( r=0.428, P=0.009), left DCG ( r=0.359, P=0.031) and right PCG ( r=0.350, P=0.037) in the cerebellar infarction patients. The RAVLT scores showed a significantly positive correlation with Eglob ( r=0.338, P=0.044). The TMT-A time-consuming and left DCG had significant negative correlation ( r=0.357, P=0.032). TMT-B time-consuming was significantly negatively correlated with right DCG ( r=-0.432, P=0.008), right PCUN ( r=-0.350, P=0.036) and left DCG ( r=-0.398, P=0.016), and positively correlated with Lp ( r=0.406, P=0.014). Conclusions:There is cognitive dysfunction in multiple domains after acute cerebellar infarction, including memory, executive function, visuospatial ability and attention. At the same time, there are reduced efficiency of information transmission in bilateral PCUN, PCG and DCG, and the frontal temporal lobe; among them, the abnormal changes of the right PCG, bilateral DCG, and right PCUN may play key roles in cognitive dysfunction.

Objective: To investigate the expression of LIM domain binding 2 (LDB2) in lung cancer tissues and its correlation with sphingosine-1 phosphate receptor 1 (S1PR1). Methods: Lung cancer tissues and the corresponding adjacent tissues from 52 patients in Nantong Tumor Hospital during April 2010 and May 2011 were collected as the experimental group and the control group, respectively. The expression levels of LDB2 and S1PR1 were detected by the real-time PCR (qRT-PCR). The expression results of LDB2 gene were further verified by the Oncomine database, and its correlations with clinicopathological parameters were analyzed. The ROC curve was drawn to evaluate the diagnosis value of LDB2 expression in lung cancer. The correlation of LDB2 expression with the prognosis of lung cancer was analyzed by the “Kaplan-Meier Plotter” database. In addition, the relationship between LDB2 and S1PR1 was also analyzed. Results: The expression levels of LDB2 in lung cancer tissues (0.158 [0.062,0.383]) were significantly lower than that in the adjacent tissues (0.403 [0.261,0.711], U=700.0, P＜ 0.01). A total of 9 eligible studies were retrieved from the Oncomine database, and their expressions of LDB2 were also low (P＜0.01). The expressions of LDB2 in lung cancer tissues were not related to gender, age, smoking history, pathological type, tumor size, TNM staging and lymphatic metastasis (P＞0.05). The results of ROC curve showed that when the area under the ROC curve (AUC ROC ) was 0.741 (95% CI:0.643-0.839) and the cut-off value was 0.247, the sensitivity and specificity of LDB2 in the diagnosis of lung cancer were 80.8% and 61.5%, respectively. The Kaplan-Meier survival analysis showed that the 5-year overall survival time of the patients with low expression of LDB2 was shorter than that of the patients with high expression of LDB2(P＜0.01). In addition, the expression levels of S1PR1 in lung cancer tissues (0.710[0.337,1.523]) were significantly lower than that in the adjacent tissues (1.582[0.913,3.533],U=780.0, P＜0.01), and the expression levels of S1PR1 in lung cancer tissues were positively correlated with that of LDB2(r=0.827,P＜0.01). Conclusion The expressions of LDB2 and S1PR1 in lung cancer tissues are down-regulated, and have a positive correlation, and they may play an important role in the occurrence and development of lung cancer.

Objective: Microtia is a relatively common birth defect, and its etiology is still unclear. In this paper, Phenolyzer, a kind of phenotype-based gene analyzer, was used to prioritize candidate genes involved in microtia. Methods: The search term " Microtia" was entered in the Phenolyzer interface. Through the steps of disease matching, gene query, gene scoring, seed gene expansion, the genetic information results of microtia were finally generated. This article traced 10 candidate genes in detail. Results: There were 13485 genes associated with microtia or related syndromes, of which 130 were seed genes. Each gene had a corresponding score, and the higher the score, the greater the correlation with the microtia. Among them, the top 10 genes included HOXA2, CHD7, CDT1, CDC6, ORC1, ORC4, ORC6, SMAD4, GLI3 and MED12. Conclusions Phenolyzer provides a detailed summary of candidate genes for microtia, providing accurate research directions for screening high-throughput sequencing results and subsequent studies.

Hepatic artery thrombosis (HAT) is the most frequent vascular complication following with liver transplantation,whichis the foremost cause of primary graft nonfunction,graft loss and recipient's death.Hepatic artery thrombosis after liver transplantation wasdivided into early hepatic artery thrombosis (E-HAT) and late hepatic artery thrombosis (L-HAT).And the etiologywascomplex,clinical presentations were diversity,treatment effects were controversial,therefore,the early detection,early diagnosis and early treatment of hepatic artery thrombosis after liver transplantation are very important.In this paper,the progress in the diagnosis and treatment of hepatic artery thrombosis after liver transplantation were reviewed.

Objective To systematically review the effect of donor ischaemic preconditioning in liver transplantation.Methods Databases including the Cochrane Library,PubMed,EMbase,CNKI,VIP and WanFang database were searched up to June 2016 for studies which involved donor ischaemic preconditioning (IPC) in liver transplantation.The data retrieved included 1-year mortality,incidence of Primary Graft Non-Functioning (PGNF),intensive therapy unit (ICU) hospitalization and liver function tests which were used to evaluate the treatment outcomes.The data were analyzed using both the fixed-effect and the random-effects models.For categorical outcomes,risk ratio (RR) with 95％ confidence intervals (CI) were calculated.For continuous outcomes,the mean difference (MD) with 95％ CI were calculated.The metaanalysis was performed using Review Manager 5.2 software.Results Six clinical studies with 322 patients were qualified for this meta-analysis.There were no significant differences in the 1-year mortality (OR =0.51,95％ CI 0.24 ～ 1.05,P ＞ 0.05),PGNF (OR =0.33,95％ CI 0.08 ～ 1.40,P ＞ 0.05) and ICU hospitalization (OR =-0.17,95 ％ CI-2.72 ～ 2.38,P ＞ 0.05) between the donor ischaemic preconditioning and the control groups.There were also no significant differences in the transaminase and bilirubin levels on postoperative day 1,3 and 7 between the two groups.Conclusion There is currently not enough evidence in evidenced based medicine to recommend the routine use of ischaemic preconditioning in donor liver retrieval.

Objective To study the correlation between the sonographic features of papillary thyroid microcarcinoma (PTMC) and high volume lymph node metastasis. Methods Medical records of 463 PTMC patients were reviewed. Cases of all patients are completed with lymph node metastasis identified by histopathology. Sonographic features such as lesion number, lesion size, echogenicity, calcification, envelope and vascularity of papillary microcarcinoma are recorded. Univariate and multivariate analysis was performed to investigating relationship between sonographic features and high volume lymph node metastasis. Results Twenty four patients have high volume central lymph node metastasis (5.2%, 24/463), in univariate analysis,sex(11.2% in male vs 3.4% in female),age(8.3% in<45 years vs 2.4% in≥45 years),calcification(8.3% in micro vs 0.0% in coarse, 3.2% in mixed and 0.7% in non) , extracapsular invasion (9.3% with vs 3.2% without)and size(9.2% in ≥7 mm vs 2.5% in <7 mm)showed significant difference;multiple logistic regression analysis showed that male(OR=3.205,P=0.009),age<45 years(OR=2.923,P=0.031), microcalcification(OR=9.380,P=0.031)and tumor size≥7mm(OR=3.272,P=0.013)is independent risk factor for high volume lymph node metastasis in the central compartment of PTMC. 10 patients have high volume lateral lymph node metastasis(2.2%,10/463),in univariate analysis,age(4.1% in<45 years vs 0.4% in≥45 years),number of lesions(5.3% in multiple vs 0.9% in single)showed significant difference;multiple logistic regression analysis showed that age < 45 years (OR=11.939,P=0.024) and multiple lesion (OR=7.247, P=0.007) is independent risk factor for high volume lymph node metastasis in the lateral compartment of PTMC. Conclusion Sonographic features of primary papillary microcarcinoma of the thyroid has correlation with high volume lymph node metastasis.
