Abstract
BACKGROUND Gastric Cancer (GC) characteristically exhibits heterogeneous responses to treatment, particularly in relation to immuno plus chemo therapy, necessitating a precision medicine approach. This study is centered around delineating the cellular and molecular underpinnings of drug resistance in this context. METHODS We undertook a comprehensive multi-omics exploration of postoperative tissues from GC patients undergoing the chemo and immuno-treatment regimen. Concurrently, an image deep learning model was developed to predict treatment responsiveness. RESULTS Our initial findings associate apical membrane cells with resistance to fluorouracil and oxaliplatin, critical constituents of the therapy. Further investigation into this cell population shed light on substantial interactions with resident macrophages, underscoring the role of intercellular communication in shaping treatment resistance. Subsequent ligand-receptor analysis unveiled specific molecular dialogues, most notably TGFB1-HSPB1 and LTF-S100A14, offering insights into potential signaling pathways implicated in resistance. Our SVM model, incorporating these multi-omics and spatial data, demonstrated significant predictive power, with AUC values of 0.93 and 0.84 in the exploration and validation cohorts respectively. Hence, our results underscore the utility of multi-omics and spatial data in modeling treatment response. CONCLUSION Our integrative approach, amalgamating mIHC assays, feature extraction, and machine learning, successfully unraveled the complex cellular interplay underlying drug resistance. This robust predictive model may serve as a valuable tool for personalizing therapeutic strategies and enhancing treatment outcomes in gastric cancer.

Abstract
Metastasis is responsible for at least 90% of colon cancer (CC)-related deaths. Lipid metabolism is a critical factor in cancer metastasis, yet the underlying mechanism requires further investigation. Herein, through the utilisation of single-cell sequencing and proteomics, we identified sulfotransferase SULT2B1 as a novel metastatic tumour marker of CC, which was associated with poor prognosis. CC orthotopic model and in vitro assays showed that SULT2B1 promoted lipid metabolism and metastasis. Moreover, SULT2B1 directly interacted with SCD1 to facilitate lipid metabolism and promoted metastasis of CC cells. And the combined application of SCD1 inhibitor CAY with SULT2B1- konockout (KO) demonstrated a more robust inhibitory effect on lipid metabolism and metastasis of CC cells in comparison to sole application of SULT2B1-KO. Notably, we revealed that lovastatin can block the SULT2B1-induced promotion of lipid metabolism and distant metastasis in vivo. Further evidence showed that SMC1A transcriptionally upregulated the expression of SULT2B1. Our findings unveiled the critical role of SULT2B1 in CC metastasis and provided a new perspective for the treatment of CC patients with distant metastasis.

Abstract
Gastric cancer stem cells (GCSCs) are strongly associated with the refractory characteristics of gastric cancer, including drug resistance, recurrence, and metastasis. The prognosis for advanced gastric cancer patients treated with multimodal therapy after surgery remains discouraging. GCSCs hold promise as therapeutic targets for GC patients. We obtained 26 sets of stem cell-related genes from the StemChecker database. The Consensus clustering algorithm was employed to discern three distinct stemness subtypes. Prognostic outcomes, components of the tumor microenvironment (TME), and responses to therapies were compared among these subtypes. Following this, a stemness-risk model was formulated using weighted gene correlation network analysis (WGCNA), alongside Cox regression and random survival forest analyses. The C2 subtype predominantly showed enrichment in negative prognostic CSC gene sets and demonstrated an immunosuppressive TME. This specific subtype exhibited minimal responsiveness to immunotherapies and demonstrated reduced sensitivity to drugs. Four pivotal genes were integrated into the construction of the stemness model. Gastric cancer patients with higher stemness-risk scores demonstrated poorer prognoses, a greater presence of immunosuppressive components in TME, and lower rates of treatment response. Subset analysis indicated that only the low-stemness risk subtype derives benefit from 5-fluorouracil-based adjuvant chemotherapy. The model's effectiveness in immunotherapeutic prediction was further validated in the PRJEB25780 cohort. Our study categorized gastric cancer patients into three stemness subtypes, each demonstrating distinct prognoses, components of TME infiltration, and varying sensitivity or resistance to standard chemotherapy or targeted therapy. We propose that the stemness risk model may help the development of well-grounded treatment recommendations and prognostic assessments.

Abstract
(1) Background: This study aimed to establish a nomogram model for predicting the overall survival (OS) of medullary thyroid carcinoma (MTC) patients based on the Surveillance, Epidemiology, and End Results (SEER) database. (2) Methods: Patients with MTC in the SEER database from 2004 to 2015 were included and divided into a modeling group and an internal validation group. We also selected MTC patients from our center from 2007 to 2019 to establish an external validation group. Univariate and multivariate Cox regression analyses were used to screen for significant independent variables and to establish a nomogram model. Kaplan-Meier (K-M) curves were plotted to evaluate the influence of the predictors. The C-indexes, areas under the curves (AUCs), and calibration curves were plotted to validate the predictive effect of the model. (3) Results: A total of 1981 MTC patients from the SEER database and 85 MTC patients from our center were included. The univariate and multivariate Cox regression analyses showed that age, tumor size, N stage, and M stage were significant factors, and a nomogram model was established. The C-index of the modeling group was 0.792, and the AUCs were 0.811, 0.825, and 0.824. The C-index of the internal validation group was 0.793, and the AUCs were 0.847, 0.846, and 0.796. The C-index of the external validation group was 0.871, and the AUCs were 0.911 and 0.827. The calibration curves indicated that the prediction ability was reliable. (4) Conclusions: A nomogram model based on age, tumor size, N stage, and M stage was able to predict the OS of MTC patients.

Abstract
OBJECTIVE Hyperlipidemic acute pancreatitis (HLAP) remains one of the major digestive emergencies with increasing health risks. Oral refeeding tolerant (ORT) and enteral tube feeding tolerant (ETFT) are commonly used for nutritional management in HLAP. However, the differences between ORT and ETFT are yet to be characterized. PATIENTS AND METHODS This study included consecutive patients admitted to the Ordos Central Hospital between January 2019 and April 2023, with predefined inclusion criteria. RESULTS A total of 335 HLAP patients were recruited according to the inclusion criteria. 268 patients were diagnosed with moderately severe acute pancreatitis (MSAP), of which 193 were in the OFT group and 75 in the ETFT group. In the ETFT group, abdominal pain and abdominal distension were significantly higher than that in the OFT group. No significant result was identified in the laboratory data. However, the OFT group showed a higher hospitalization and cost, as well as exocrine insufficiency and newly onset diabetes, than the ETFT group. CONCLUSIONS Based on the incidence of HLAP retrieved in this study, MSAP is the major type with increasing clinical value. From the nutritional management sense, patients who received OFT showed higher hospitalization and cost, as well as lower exocrine insufficiency and newly onset diabetes.

Abstract
To solve the problems of poor stability and low monitoring precision in the online detection of rice moisture in the drying tower, we designed an online detection device for rice moisture at the outlet of the drying tower. The structure of a tri-plate capacitor was adopted, and the electrostatic field of the tri-plate capacitor was simulated using COMSOL software. A central composite design of three factors and five levels was carried out with the thickness, spacing, and area of the plates as the influencing factors and the capacitance-specific sensitivity as the test index. This device was composed of a dynamic acquisition device and a detection system. The dynamic sampling device was found to achieve dynamic continuous sampling and static intermittent measurements of rice using a ten-shaped leaf plate structure. The hardware circuit of the inspection system with STM32F407ZGT6 as the main control chip was designed to realize stable communication between the master and slave computers. Additionally, an optimized BP neural network prediction model based on the genetic algorithm was established using the MATLAB software. Indoor static and dynamic verification tests were also carried out. The results showed that the optimal plate structure parameter combination includes a plate thickness of 1 mm, plate spacing of 100 mm, and relative area of 18,000.069 mm2 while satisfying the mechanical design and practical application needs of the device. The structure of the BP neural network was 2-90-1, the length of individual code in the genetic algorithm was 361, and the prediction model was trained 765 times to obtain a minimum MSE value of 1.9683 × 10-5, which was lower than that of the unoptimized BP neural network with an MSE of 7.1215 × 10-4. The mean relative error of the device was 1.44% under the static test and 2.103% under the dynamic test, which met the accuracy requirements for the design of the device.

Abstract
Alzheimer's disease (AD) is one of the major worldwide causes of dementia that is characterized by irreversible decline in learning, memory loss, and behavioral impairments. Mitophagy is selective autophagy through the clearance of aberrant mitochondria, specifically for degradation to maintain energy generation and neuronal and synaptic function in the brain. Accumulating evidence shows that defective mitophagy is believed to be as one of the early and prominent features in AD pathogenesis and has drawn attention in the recent few years. APOE ε4 allele is the greatest genetic determinant for AD and is widely reported to mediate detrimental effects on mitochondria function and mitophagic process. Given the continuity of the physiological process, this review takes the mitochondrial dynamic and mitophagic core events into consideration, which highlights the current knowledge about the molecular alterations from an APOE-genotype perspective, synthesizes ApoE4-associated regulations, and the cross-talk between these signaling, along with the focuses on general autophagic process and several pivotal processes of mitophagy, including mitochondrial dynamic (DRP1, MFN-1), mitophagic induction (PINK1, Parkin). These may shed new light on the link between ApoE4 and AD and provide novel insights for promising mitophagy-targeted therapeutic strategies for AD.

Abstract
Objective To probe into the role of pyroptosis-related genes in gastric cancer. Methods To establish pyroptosis-related genes, observe their expression in gastric cancer, and analyze the prognosis of pyroptosis-related genes in gastric cancer by single-factor COX, which showed that only GSDME had prognostic significance in gastric cancer. The mRNA expression profiles and lncRNA expression profiles of gastric cancer downloaded from the Cancer Genome Atlas were combined for weighted gene regulatory network analysis, after which the lncRNA nodes of the module to which GSDME belongs were extracted to obtain the lncRNAs−GSDME interactions, which were visualized with Cytoscape network plots. Finally, the effects of GSDME on the proliferation, migration, and apoptosis of gastric cancer cells were observed with CCK8, and flow cytometry. Results Our results show that only GSDME has prognostic significance in gastric cancer, and show that it has an important role in a variety of tumors. In addition, our results show that 16 lncRNAs have a significant interaction with GSDME. Finally, the experimental analysis showed that knocking down the expression level of GSDME could affect the growth as well as apoptosis of gastric cancer cells. Conclusion The significant prognostic significance of GSDME in gastric cancer and the fact that affecting GSDME expression inhibits gastric cancer cell growth suggest that GSDME can be used as a predictive biomarker.

Abstract
Background Globally, lung cancer is one of the most malignant tumors, of which lung adenocarcinoma (LUAD) is the most common subtype, with a particularly poor prognosis. Ciclopirox olamine (CPX) is an antifungal drug and was recently identified as a potential antitumor agent. However, how CPX and its mechanism of action function during LUAD remain unclear. Methods The effects of CPX on cell proliferation, cell cycle, reactive oxygen species (ROS) levels, and apoptosis were assessed using the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-2H-tetrazolium bromide (MTT) assay, colony formation, western blotting, flow cytometry assays, and immunohistochemistry. Global gene expression levels were compared between control and CPX-treated LUAD cells. A LUAD xenograft mouse model was used to evaluate the potential in vivo effects of CPX. Results We observed that CPX displayed strong antitumorigenic properties in LUAD cells, inhibited LUAD proliferation, induced ROS production, caused DNA damage, and activated the ATR-CHK1-P53 pathway. Topoisomerase II alpha (TOP2A) is overexpressed in LUAD and associated with a poor prognosis. By analyzing differentially expressed genes (DEGs), TOP2A was significantly down-regulated in CPX-treated LUAD cells. Furthermore, CPX treatment substantially inhibited in vivo LUAD xenograft growth without toxicity or side effects to the hematological system and internal organs. Conclusions Collectively, for the first time, we showed that CPX exerted tumor-suppressor effects in LUAD via TOP2A, suggesting CPX could potentially function as a promising chemotherapeutic for LUAD treatment.

Abstract
BACKGROUND Numerous common oncogenic driver events have been confirmed in non-small cell lung cancer (NSCLC). Although targeted therapy has revolutionized NSCLC treatment, some patients still do not respond. NCAPG, also known as non-SMC condensin I complex subunit G, was positively associated with proliferation and migration in several tumor types. METHODS We used transcriptional sequencing and TCGA database analysis to identify NCAPG as a new therapeutic target for NSCLC. The oncogenic roles of NCAPG in NSCLC tumor growth and metastasis were detected in vitro and in vivo. Ncapg+/+ or Ncapg+/- mice with urethane treatment were analyzed for oncogenesis of NSCLC. RESULTS We investigated NCAPG as a new oncogenic driver which promoted NSCLC tumorigenesis and progression. We used transcriptome sequencing and the Cancer Genome Atlas (TCGA) database analysis to screen and found that NCAPG was negatively correlated with NSCLC survival. Using immunohistochemistry, we demonstrated that NCAPG overexpression was an independent risk factor for NSCLC survival. Functionally, NCAPG knockdown inhibited proliferation, migration, and invasion of NSCLC cells in vitro and in vivo. We exposed wildtype or Ncapg+/- mice to urethane and discovered that urethane-induced lung tumors were reduced in Ncapg+/- mice. Mechanistically, the function of NCAPG in promoting initiation and progression of NSCLC was closely related to LGALS1, which was also upregulated in NSCLC and might interact directly with NCAPG. CONCLUSIONS This study indicates that NCAPG is one of the essential factors for NSCLC oncogenesis and progression, providing a new target for prognosis prediction and treatment of NSCLC.

Abstract
Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers, with a poor 5-year survival rate of approximately 6%, mostly due to poor treatment response and early progression. The S100 gene family participates in various pathophysiological processes in various malignancies. S100A16 is a member of the S100 family, which is abnormally expressed in PDAC; however, its biological functions and mechanisms of action remain unclear. We analysed the Gene Expression Omnibus (GEO) public database and the gene ChIP data collected in our previous study of human PDAC cell line PANC-1 cocultured with M2 macrophages to identify differentially expressed genes (DEGs). Twenty-three overexpressed genes were identified by screening. Then, the selected genes were analysed using The Cancer Genome Atlas (TCGA) database to assess whether they have significant impact on the overall survival (OS) of PDAC patients. Of the 14 DEGs identified, S100A16 was associated with poor prognosis and was selected for further investigation; the results indicate that S100A16 is positively correlated with epithelial-mesenchymal transition (EMT)-related genes in the TCGA dataset. Subsequent in vitro and in vivo experiments demonstrated that S100A16 induces the EMT to promote the metastasis of human PDAC cells and that the effect is mediated by the enhanced expression of TWIST1 and activation of the STAT3 signalling pathway. The antitumour effect of gemcitabine (GEM) was enhanced in combination with S100A16 downregulation. In conclusion, our findings suggest that S100A16 is a novel potential therapeutic target for human PDAC treatment.

Abstract
BACKGROUND It is known that there are insufficient prognostic factors for non-small cell lung cancer (NSCLC). It was reported that PD-L1 was a prognostic factor for NSCLC,and c-Myc regulated the expression of PD-L1. Herein, we investigated c-Myc and PD-L1 expression and their association with overall survival (OS) in NSCLC. METHODS Formalin-fixed paraffin-embedded specimens were obtained from 128 patients with surgically resected primary NSCLC. Immunohistochemistry was used to assess the expression of PD-L1 and c-Myc in this study. Pearson's Chi squared test or Fisher's exact test was used to analyze the correlation of the expression of PD-L1 and c-Myc with clinicopathologic features. The relationship between OS and the expression of PD-L1 and c-Myc was evaluated by the Kaplan-Meier method and Cox proportional hazards model, respectively. RESULTS Positive expression of PD-L1 was detected in 59 patients (46.1%). Patients with negative expression of PD-L1 had remarkably longer OS than those with positive expression of PD-L1. The positive expression rate of c-Myc in NSCLC accounted for 58.6% (75/128) and its expression was significantly more frequent in males (p = 0.002) and patients with lymph node metastasis (p = 0.029). PD-L1 expression was positively correlated with c-Myc expression (r = 0.459, p < 0.001). The PD-L1 and c-Myc double-positive group had a worse prognosis than other subgroups (p < 0.05), and the PD-L1 and c-Myc double-negative group had a better OS than other subgroups (p < 0.05). CONCLUSION Conjoint analysis of the expression of PD-L1 and c-Myc was a better prognostic approach for NSCLC patients.

Abstract
Melanoma is a rare malignancy that invades the skin and the mucosa. Research has been conducted on melanoma incidence and the survival of patients with melanoma; however, no studies in melanoma incidence and the survival spanning 40 years and based on a large population have thus far been reported. We obtained data on patients with melanoma for each decade from 1974 to 2013 from the Surveillance, Epidemiology, and End Results (SEER) database. Disparities in survival by decade, age group, gender, race, site, and socioeconomic status (SES) within the aforementioned period were analyzed by comparison of Kaplan-Meier curves. We collected data on 133,996 melanoma patients in 18 SEER registry regions for the period 1974-2013. Our study found that the melanoma incidence increased continuously for the total population as well as for most age groups. The survival of patients with melanoma (except mucosal melanoma) also increased. This study showed increases in incidence and survival in melanoma across four decades in a large sample; meanwhile, the survival rates for mucosal melanoma decreased in the latter three decades, suggesting the need to improve melanoma diagnosis, broaden melanoma awareness among health care providers, and initiate the development of more effective treatments than the existing ones.

Abstract
We discuss the design, fabrication, and testing of prototype horn-coupled, lumped-element kinetic inductance detectors (LEKIDs) designed for cosmic microwave background studies. The LEKIDs are made from a thin aluminum film deposited on a silicon wafer and patterned using standard photolithographic techniques at STAR Cryoelectronics, a commercial device foundry. We fabricated 20-element arrays, optimized for a spectral band centered on 150 GHz, to test the sensitivity and yield of the devices as well as the multiplexing scheme. We characterized the detectors in two configurations. First, the detectors were tested in a dark environment with the horn apertures covered, and second, the horn apertures were pointed towards a beam-filling cryogenic blackbody load. These tests show that the multiplexing scheme is robust and scalable, the yield across multiple LEKID arrays is 91%, and the measured noise-equivalent temperatures for a 4 K optical load are in the range 26±6 μK√s.

Abstract
BACKGROUND To explore the feasibility and toxicity of preoperative neoadjuvant chemotherapy followed by surgery in the treatment of stage III NSCLC and to evaluate its effects on tumor response, resection rate, tumor downstaging, and survival rate. METHODS From Jan. 1990 to Jan. 2001, 624 patients were randomly devided into group A ( preoperative neoadjuvant chemotherapy group) and group B ( control group, without neoadjuvant chemotherapy) . Group A had 314 patients and group B had 310 cases. The patients in group A were give 2 cycles of neoadjuvant chemotherapy, and operations were performed in 4 weeks after finishing the last chemotherapy. Twenty-one patients were given bronchial artery intervensional chemotherapy. The other 293 cases were given intravenous chemotherapy. The regimens included MVP in 68 cases, CAP in 36 cases, EP in 67 cases, VIP in 20 cases, Gem+ DDP in 30 cases, NVB+ DDP in 32 cases, Taxol+ NVB in 30 cases, and Taxol+ DDP in 10 cases. The patients in group B were firstly operated. Thoracic radiation therapy of 50-55 Gy was g iven in the patients with N1 and N2 disease both in group A and group B. RESULTS The tumor response to induction chemotherapy was 73. 57%( 231/ 314) in group A. The tumor downstaging was 43. 63%( 137/ 314) . The histological complete response was 15. 92%( 50/ 314) . The resection rate was 97. 69% in group A, and 91. 94% in group B. No significant differences of blood loss, operative complications and mortality were observed between the group A and group B. The 1-, 3-, 5- and 10-year survival rates were 89. 35%, 67. 46% , 34. 39% and 29. 34% in group A, and 87. 53%, 51. 54%, 24. 19% and 21. 64% in group B respectively. The long-term survival rate in group A was remarkably higher than that in group B ( P < 0. 01) . CONCLUSIONS The results demonstrate that the preoperative neoadjuvant chemotherapy is safe and effective. It is helpful to decrease the tumor staging , to increase the resection rate of the tumor, and to improve the long-term survival rate and life qualities of patients with stage III NSCLC.

Abstract
The aim of this study was to retrospectively review our experience of performing simultaneous operations on concomitant diseases in the esophagus and lungs. From January 1998 to July 2009, simultaneous operations were performed on 13 patients with concomitant esophageal and pulmonary diseases, using coordinated surgical approaches. Among the 13 patients, six had primary cancers in the esophagus and lungs, five had primary esophageal cancer accompanied by a benign pulmonary disease, one had benign diseases in both esophagus and lung, and one had primary esophageal cancer with metastasis to the left lower lung. All patients survived the operations. Two major complications occurred postoperatively. One complication was bronchopleural fistula and the other was intrathoracic gastric laceration. Both patients recovered after additional treatments. Simultaneous operation of concomitant diseases in the esophagus and lungs is feasible and safe in selected patients who have received careful preoperative assessment, well-designed surgical approach, and proper perioperative management.

Abstract
A 23-year-old female patient was treated for a posterior mediastinal tumor of unknown histology. Her systemic blood pressure increased rapidly to a critical level immediately after starting surgical manipulation of the tumor, which was suggestive of a hyperfunctioning pheochromocytoma. The tumor was removed after controlling the blood pressure and was histologically diagnosed as an extra-adrenal pheochromocytoma. Further postoperative investigations showed the tumor to be a sporadic type through further postoperative investigations and the patient had subsequently an uneventful course.

Abstract
Nm23 is a metastasis suppressor gene. In this report, we transfected nm23-H1 cDNA into L9981, a human large cell lung cancer cell line with nm23 negative expression, and made a stable transfectant. L9981-nm23-H1 cells exhibited lower cells proliferation rate, more G0/G1 phase growth and an increase in apoptosis with a dramatic decreased in the tumor cells ability to metastasize. L9981-nm23-H1 cells also demonstrated a significantly reduced lymph node and pulmonary metastatic capacity in vivo when injected into the nude mice. Furthermore, we used DNA microarray analysis to explore the change in expression of the metastasis-related genes in L9981-nm23-H1 cells. We found that the expression of beta-Catenin, E-Cadherin and TIMP-1 were significantly increased while expression MMP-2, CD44v6, and VEGF was dramatically decreased in L9981-nm23-H1, as confirmed by RT-PCR and western blot. These results demonstrated that nm23-H1 can suppress the mobility and metastatic capacity of cancer cells and the molecular mechanism by which nm23-H1 suppresses tumor metastasis may be via increasing the expression of metastasis-related genes such as beta-Catenin, E-Cadherin and TIMP-1 and decreasing the expression of MMP-2, CD44V6 and VEGF.

Abstract
BACKGROUND To explore the relationship between VEGF and mutant p53 ( mtp53) expression and its relation to the physiopathological characteristics of lung neoplasms. METHODS The expression of VEGF and mtp53 was detected in 120 lung cancer lesions, paracancerous lesions and 40 benign pulmonary lesions by immunohistochemical staining ( LSAB methods) . RESULTS VEGF and mtp53 gene expressions in lung cancer tissues were significantly higher than those in paracancerous and benign pulmonary tissues ( P < 0. 01) . VEGF and mtp53 expression was closely related to the size of primary cancer, lymph node status, P-TNM stages, cell differentiation grade of lung cancer ( P < 0. 01) . A highly positive relation was found between VEGF and mtp53( P < 0. 01) . CONCLUSIONS The results suggest that expression of VEGF and mtp53 gene may plays an important role in the oncogenesis and development of lung cancer and may be served as a tumor marker to evaluate the biological behavior of lung cancer.

Abstract
BACKGROUND To explore the role of the allelic deletion and mutation of FHIT gene on the carcinogenesis and development of lung cancer. METHODS The allelic alterations of FHIT gene and microsatellites D3S1300, D3S1312,D3S1313 were detected in 35 cancer samples of NSCLC, their corresponding normal tissues, and 4 lung cancer cell lines, and 10 lung tissues of benign pulmonary lesions as control by PCR-SSCP and DNA sequence. RESULTS Loss of heterozygosity (LOH) affecting at least one locus of FHIT gene was observed in 22 out of 35 tumors, with a LOH rate of 62.86%. LOH of FHIT gene in squamous cell carcinoma (88.24%) was significantly higher than that in adenocarcinoma (38.89%) (P<0.01). The LOH rate of FHIT gene in smoking patients (76.19%) was also significantly higher than that in non-smoking patients (42.86%)(P<0.05).No significant relationship was found among the LOH of FHIT and cell differentiation, P-TNM stages, size of primary tumor, location of cancer and age of the patients (P>0.05). LOH of FHIT was also detected in Lewis lung cancer and A549 cell lines. Mutation of microsatellite D3S1312 was observed in 4 lung cancer tissues. DNA sequence showed that C->T mutation occurred in the 87 codon of microsatellite D3S1312. CONCLUSIONS The alteration of FHIT gene is mainly allelic loss and the frequency of allelic mutation is rare. FHIT gene alterations preferentially occur in squamous cell carcinoma patients and smokers, and FHIT gene may be a candidate molecular target of carcinogenesis in tobacco smoker. Allelic deletion of FHIT gene might be an early molecular event in smoking-related lung cancer.

Abstract
The purpose of this study was to evaluate the preliminary results after prosthetic valve replacement of preserving the subvalvular apparatus with artificial chorade for mitral stenosis. 20 patients had received operation with expanded polytetrafluoroethylene(e-PTFE) as artificial chordade. The patients were followed up by means of echocardiography. The time of follow-up study varied from 4 to 18 months with a mean of 6 months. The left atrial, ventricular dimension as well as ventricular function were assessed. In addition, the length of artificial chorade and obstruction of left ventricular outflow track were observed. The results showed that left atrial diameter (LAD, from 57.59 +/- 13.51 mm to 47.05 +/- 9.55 mm), left ventricular end-diastolic dimension (LVEDD, from 46.23 +/- 12.56 mm to 42.41 +/- 10.86 mm), left ventricular end-systolic dimension (LVESD, from 33.50 +/- 10.20 mm to 29.68 +/- 8.40 mm) decreased (P < 0.01), and ejection fraction (EF, from 52.59 +/- 11.89% to 58.36 +/- 8.03%) increased (P < 0.05) after operation. There were no significant changes of fractional shortening (FS, from 29.23 +/- 8.99% to 31.05 +/- 6.08%). The length of artificial chorade ranged from 2.6 cm to 4.3 cm (the mean, 3.2 cm). There was no case of obstruction of left ventricular outflow track. It is believed that the result of preliminary echocardiographic observation on prosthetic valve replacement of preserving the subvalvular apparatus with artificial chorade for mitral stenosis is satisfactory.

Abstract
BACKGROUND To analyze the risky factors of post-operative respiratory failure in patients with lung cancer. METHODS Thirty-six cases of lung cancer with post-operative respiratory failure and 72 controls were analyzed by Chi-Square analysis and Logistic Regression. RESULTS MVV , RV/ TLC , FEV1 , BR , V25 , MMEF and DLCO in respiratory failure group were all significantly lower than those in control group ( P < 0. 05) . The post-operative chest drainage and perioperative intravenous perfussion in respiratory failure group were significantly more than those in control group ( P < 0. 05) . The odds of respiratory failure was much lower in sleeve resection and lobectomy group than in pneumonectomy group. CONCLUSIONS Severe obstruction of small airway , diffusion capacity and large amount perioperative intravenous infusion are the risky factors of post-operative respiratory failure in lung cancer patients , and bronchoplastic or/ and pulmonary artery reconstruction as a curative operation can significantly prevent the post-operative respiratory failure.
