RESUMO
Objective: To explore the feasibility of using ultrasonic convex array probe compressing abdominal wall to increase success rate of external cephalic version (ECV) without anesthesia in full-term and near-term pregnancy. Methods: Totally 190 singleton and non-cephalic presentation pregnant women in 36-39+4 weeks of gestation performed ECV from April 2019 to August 2023 in the First Affiliated Hospital of Nanjing Medical University were analyzed. According to whether use the ultrasound probe compressing fetal breech or not, the pregnant women were divided into two groups: 81 cases in the probe-compressing group (including primipara 61 cases and multipara 20 cases) and 109 cases in the non-probe-compressing group(including primipara 72 cases and multipara 37 cases). Clinical data, ECV related factors and complications were analyzed and compared between the two groups. Results: (1) The overall success rate of ECV was 64.2% (122/190). There was no significant difference in the success rate of ECV between probe-compressing group and non-probe-compressing group [69.1% (56/81) vs 60.6% (66/109), χ2=1.490, P=0.222]. The total vaginal delivery rate after successful ECV was 81.1% (99/122), while 71.1% (54/76) in primipara and 97.8% (45/46) in multipara, respectively. (2) Compare to the non-probe-compressing group, the success rate of ECV in primipara was significantly higher in the probe-compressing group [45.8% (33/72) vs 70.5% (43/61)], but the gestational age was shorter and the height was higher in the probe-compressing group (all P<0.05). The success rate of ECV of multipara in the probe-compressing group (65.0%, 13/20) was lower than that in the non-probe-compressing group (89.2%, 33/37), but there was no significant difference between the two groups (P>0.05). (3) Multivariate logistic regression analysis showed that abdominal wall compressed by ultrasound probe (OR=2.601, 95%CI: 1.113-6.075; P=0.027) and amniotic fluid index (AFI; OR=1.010, 95%CI: 1.001-1.020; P=0.028) were positive factors for the successful rate of ECV in primipara pregnant women. (4) The main complication of ECV was transient fetal heart rate reduction (8.9%,17/190), the incidence in the probe-compressing group was significantly higher than that in the non-probe-compressing group [14.8% (12/81) vs 4.6% (5/109); χ2=5.967, P=0.015]. No statistical differences were found in rates of complications between the ECV successful and unsuccessful pregnant women, and between probe-compressing and non-probe-compressing groups (all P>0.05). No adverse maternal and neonatal outcomes related to ECV were observed. Conclusions: The ultrasonic convex array probe compressing could significantly improve the success rate of ECV in primipara without increasing the incidence of adverse maternal and fetal outcomes. The success rate of ECV in primipara is influenced by AFI and operation mode.

The etiology of hemoptysis is diverse and complex, with aorta aneurysm being identified as a rare cause of cryptogenic hemoptysis. Here, we reported a 56-year-old male patient who experienced hemoptysis due to a thoracic aorta aneurysm that persisted despite stent implantation. Further investigation revealed the presence of a lateral thoracic artery-pulmonary artery fistula and an aortobronchial fistula, diagnosed by angiography and multidisciplinary consultation. Therefore, patients with recurrent hemoptysis after aortic surgery should be monitored for the possibility of an aortobronchial fistula.

OBJECTIVE: To evaluate the efficacy of an electro-mechanical film-based(EMFi) multi-parameter pressure sensitive sleep monitor(MPSSM)on clinical diagnosis and research significance of obstructive sleep apnea hypopnea syndrome(OSAHS). METHODS: Retrospective analysis was made of 58 test subjects at Peking University Third Hospital with suspected OSAHS who were simultaneously monitored by MPSSM and polysomnography(PSG). The PSG test results were used as the gold standard in evaluating the sensitivity and specificity of OSAHS diagnosis of MPSSM. The test result consistency of sleep apnea and hypopnea index(AHI)and total apnea time of the two methods was evaluated. Real-time waveform comparison of sleep respiratory events of a randomly selected patient diagnosed with OSAHS was performed. RESULTS: For 58 test subjects, 48 were male, 10 were female, with an average age of(40.6±12.2)years. Thirty-nine out of the 58 test subjects were diagnosed with OSHAS by PSG. The sensitivity of MPSSM for OSAHS diagnosis was 92.3%, with 95% confidence interval of 79.1%-98.4%, and the specificity of MPSSM for OSAHS diagnosis was 100%, with 95% confidence interval of 82.3%-100%. Kappa test k=0.887 (P < 0.001) showed OSAHS diagnosis results of the two methods were almost identical. The AHI measured by MPSSM [12.0(2.6-32.2) times/h] and PSG [13.4(3.1-38.8) times/h] were highly correlated (ρ=0.939, P < 0.001). The total apnea time measured by MPSSM [37.9(9.9-80.5) min] and PSG [32.3(8.6-93.0) min] were highly correlated(ρ=0.924, P < 0.001). Bland-Altman plot showed that the consistency between the test results of the two methods was very high. CONCLUSION: As a portable, non-contact, fully automatic monitoring device, MPSSM is reliable in the screening of OSAHS compared with PSG. It is suitable to be promoted and applied in primary medical institutions, nursing homes and domestic usage. However, further research is required in improving the analysis of different sleep phase and the differentiation of central sleep apnea syndrome respiratory events in order to effectively assist medical personnel in making an accurate sleep apnea diagnosis.

Objective: To evaluate the cost-effectiveness of anti-tumor associated antigen autoantibody (TAAb) for hepatocellular carcinoma (HCC) screening in cirrhosis population with chronic hepatitis B (CHB). Methods: A simulated cohort of 40-year-old patients with CHB cirrhosis was established with a sample size of 10 000. Using TAAb screening alone or TAAb and AFP screening in parallel (TAAb + AFP) as the research strategy, and liver ultrasound and AFP screening in parallel (liver ultrasound + AFP) as the control strategy, the decision analysis Markov model was constructed and the model validity was evaluated. The 6-month cycle was simulated using TreeAge Pro 2020 software. Cost and quality-adjusted life years (QALY) were calculated. Incremental cost-effectiveness ratio (ICER) was used to compare the two strategies, and sensitivity analysis was used to evaluate the uncertainty of results. Results: The Markov model had a total of 11 outcomes, of which 7 were natural outcomes and 4 wereclinical intervention outcomes, and the goodness of fit was 0.969. The lifetime screening cost of TAAb+AFP strategy for HCC screening was 249 612 yuan/case, and the QALY per capita was 7.704 years. Compared with liver ultrasound +AFP strategy (247 805 yuan/case), the total health cost increased by 1 807 yuan/case, and the QALY obtained was 0.014. The ICER was 127 635 yuan /QALY. When the TAAb screening fee was higher than 889.552 yuan, or the discount rate was higher than 0.068, or the antiviral treatment compliance was lower than 45.1%, ICER > 212 676 yuan /QALY. When the single TAAb screening fee was 400-600 yuan, the TAAB+AFP strategy had cost effective value. When the willingness to pay was 70 892, 141 784 and 212 676 yuan /QALY, the probability of cost-effectiveness of TAAb+AFP strategy was 70.6%, 75.3% and 77.8%, respectively. Conclusion: It is cost-effective to use TAAb+AFP for early screening of liver cancer in Chinese population with CHB cirrhosis.

Objective: To evaluate the expression of LEF1 protein in lymphoblastic lymphoma/acute lymphoblastic leukemia (LBL/ALL) and small B-cell lymphomas, and its value in pathologic diagnosis and differential diagnosis of LBL/ALL. Methods: 53 cases of LBL/ALL were collected at shanghai Tongji Hospital from January 2012 to December 2019. The protein expression of LEF1 and TdT was detected by immunohistochemistry in 53 paraffin-embedded tissue samples of LBL/ALL. The specificity and sensitivity of LEF1 and TdT in the diagnosis of LBL/ALL were compared. The expression of LEF1 protein in 77 cases of small B-cell lymphomas including chronic lymphocytic leukemia/small lymphoid lymphoma (CLL/SLL), follicular lymphoma, mantle cell lymphoma, marginal zone lymphoma and Waldenstrom's macroglobulinemia/lymphoplasmacytic lymphoma was studied. The correlation between LEF1 expression and overall survival (OS) and progression-free survival (PFS) was performed by univariate analysis. Results: The expression of LEF1 in LBL/ALL was 100% (53/53), the median value was 90%; the expression of TdT was 84.9% (T-LBL/ALL 78.1%, B-LBL/ALL 95.2%), the median value was 80%; the expression rate and median value of LEF1 and TdT were significantly different (P=0.008 and 0.001 respectively). The expression of LEF1 in CLL/SLL was 14/18, the median value was 45%; LEF1 was not expressed in follicular lymphoma (0/16), mantle cell lymphoma (0/16), marginal zone lymphoma (0/19), and Waldenstrom's macroglobulinemia/lymphoplasmacytic lymphoma (0/8). LEF1 expression was significantly different between B-LBL/ALL and small B-cell lymphomas. The median follow-up time of LBL/ALL cases in this group was 16 months. There was no statistical difference between LEF1 expression and the OS and PFS in LBL/ALL patients. Conclusions: Immunohistochemical staining of LEF1 has high sensitivity and good specificity in the diagnosis of LBL/ALL, and its combination with TdT can improve the diagnostic rate of LBL/ALL.

Objective: To analyze retrospectively the clinical characteristics of pathologically confirmed benign pulmonary nodules post-surgery, and therefore to provide evidence for the diagnosis of benign pulmonary nodules. Methods: 288 cases of pulmonary nodules were selected in the Ruijin Hospital from 1st January 2017 to 31st October 2019. All the lesions of these patients were confirmed by surgery and had definite pathological diagnosis. The clinical data were collected, including demography, clinical data, radiological features. Features that indicated benign pulmonary nodules were summarized. Results: The main etiologies of benign pulmonary nodules were granulomas, hamartomas, cryptococcus infection, organizing pneumonia and non-specific inflammation. In our cohort, we found that the radiological characteristics of benign nodules were single, solid, less than 10 mm in average diameter, with well-defined margins, absence of vacuole sign or vascular convergence , and negative functional imaging. Conclusion: The most common etiologies of post-surgical benign nodules were granulomas, hamartomas, and cryptococcus infection, characterized by being single, solid and with well-defined margins. Caution should be taken before considering surgery for such nodules.

Melatonin receptor type 1 (MTNR1A or MT1) is known to play an important role in cancer progression; however, its prognostic value for resected gastric adenocarcinoma (RGA) is unknown. In this study, we examined the potential of MT1 as a prognostic biomarker for RGA. The expression of the MT1 was evaluated in 67 patients with RGA by immunohistochemistry, and the relationship between MT1 levels and RGA prognosis was analyzed by Chi-square test, multivariate Cox regression, Kaplan-Meier method, and log-rank test. High MT1 expression was associated with a poor survival rate (29.0%, p=0.002) and the occurrence of metastasis (62.9%, p=0.004). Kaplan-Meier survival analysis and log rank tests revealed that patients with high expression of the MT1 had significantly shorter median overall survival compared to those with low expression (33.0 vs. 65.0 months, respectively; p=0.02). Multivariate Cox analysis indicated that the calculated death risk (hazard ratio [HR]) in patients with high expression levels of the MT1 increased to 2.68 (95% confidence interval [CI] 1.21-5.94, p=0.015), which was higher compared to those with low levels. HR of death was also high in patients with advanced T stage (2.51; 95 % CI 1.00-6.26, p=0.049) and metastasis (5.02; 95% CI 1.94-13.03, p=0.001). Our results showed that high MT1 expression in primary gastric adenocarcinoma tissues was associated with the occurrence of metastasis and poor prognosis. It may have prognostic significance as a potential biomarker in patients with RGA.

Objective: To investigate the application and efficacy of the one-stage total knee arthroplasty (TKA) of intra-articular compensation osteotomy in knee osteoarthritis(KOA) patients with extra-articular deformity (EAD). Methods: A retrospective study of 9 patients with end-stage KOA and EAD undergoing one-stage TKA from January 2014 to December 2017 in the First Affiliated Hospital of Zhejiang Chinese Medical University was performed. There were 3 males and 6 females with an average age of 56 years(range, 19-77 years);5 cases of simple coronal deformity (varus 10°-27°, mean 18.2°), 3 cases of sagittal deformity (recurvatum15°-35°, mean 22.6°), 1 case combined with coronal and sagittal deformity (varus 16°, recurvatum 31°); hemophilia dysplasia in 1 case, fracture malformation in 8 cases. Main outcome measures included the mechanical axis, range of motion (ROM) and Hospital for Special Surgery Knee Score (HSS). Results: The mean follow-up period was 33.2 months (range, 25-47 months). The mechanical axis angle was restored from 12.4°±4.1°to 1.4°±0.9°(t=7.954, P<0.01). The HSS was improved from 28±14 preoperatively to 87±7 postoperatively (t=-11.174, P=0.013). The ROM increased from 56°±22°to 99°±8° (t=-5.480, P=0.010). There was no complications such as joint instability, infection, fracture, common peroneal nerve injury and early prosthesis loosening. Conclusions: For KOA patients with femoral EAD, one-stage TKA with intra-articular compensatory osteotomy can effectively restore the mechanical axis and obtain satisfying joint function. Through a series of measures such as preoperative measurement, soft tissue evaluation and 3D printing, the accuracy of surgery can be improved and the difficulty of surgery can be reduced.

Objective: To analyze the clinical characteristics of 34 COVID-19 cases and to provide the basis for the prevention and control of the epidemic disease. Methods: Thirty-four COVID-19 patients diagnosed with RT-PCR in the isolation ward of the Fourth People's Hospital of Ningxia Hui autonomous region (infectious diseases hospital) from the January 22 to February 4, 2020 were selected as the research subjects. The clinical data were collected. Excel was used to describe the relationship between clinical classification and age distribution, contact history and date of onset. SPSS 25.0 statistical software was used for analysis. The general information, clinical symptoms, blood test, virus nucleic acid test results, epidemiology, CT imaging, treatment and prognosis were analyzed. Results: There were 5 mild cases (5/34), 24 ordinary cases (24/34), 5 severe cases (5/34). The elderly was more common in severe patients. The main clinical symptoms were fever (27/34)and dry cough(26/34). The peripheral blood showed normal or decreased leukocyte count (33/34), decreased lymphocyte count (12/34). The increase of C-reactive protein (CRP) and D-dimer was related to the severity of the disease. Some patients had mild liver and kidney damage. Six patients were diagnosed through 3 or more times of nucleic acid tests. Sixteen cases had Wuhan related history,13 cases were close contacts, 5 cases had no confirmed route. The clustered infections were found in 6 families. In typical cases, CT showed single or multiple patchy ground glass shadow with thickening of interlobular septum. In severe cases, diffuse lesions of both lungs were found, with ground glass shadow, consolidation shadow and strip shadow coexisting. Thirty-four patients were treated with interferon-α and Lopinavir/Ritonavir with good prognosis. Conclusions: The clinical characteristics of COVID-19 were similar to that of general viral pneumonia but with strong infectivity. Close contact and family aggregation caused disease outbreaks. COVID-19 could not be excluded if two nucleic acid tests were negative and high-resolution CT was helpful for differential diagnosis. Early detection, early isolation, early diagnosis and early treatment are important for good prognosis. The effectiveness of antiviral drugs needs to be further verified.

BACKGROUND: Post-operative pneumonia (Pop) following meningioma surgery is the dominant systemic complication which could cause serious threats to patients. It is unclear whether hematological biochemical markers are independently associated with the Pop. This study attempted to perform a more comprehensive study of taking both clinical factors and hematological biomarkers into account to promote the management of patients after meningioma surgery. METHODS: We collected clinical and hematological parameters of 1156 patients undergoing meningioma resection from January 2009 to January 2013. According to whether the symptoms of pneumonia had manifested,patients were divided into the Pop group and the Non-Pop group. We analyzed the distinctions of clinical factors between the two groups. We successively performed univariate and multivariate regression analysis to identify risk factors independently associated with the Pop. RESULTS: 4.4% patients infected with the Pop (51 of 1156). The median age at diagnosis of the Pop patients was significantly older than the Non-Pop group (p = 0.002). There were strike distinctions of post-operative hospital stays between two groups, with 21 days and 7 days each (p < 0.001). On multivariate analysis, tumor relapse (p < 0.001), skull base lesions (p = 0.001), intra-operative blood transfusion (p = 0.018) and cardiovascular diseases (p = 0.001) were linked with increased risk of the Pop following meningioma resection. For hematological biochemical markers, it was the factor of Red blood cell distribution width-standard deviation (RDW-SD) (OR 5.267, 95%CI 1.316, 21.078; p = 0.019) and Neutrophils lymphocytes ratio (NLR) (OR 2.081, 95%CI 1.063, 4.067; p = 0.033) that could appreciably predict the Pop. CONCLUSIONS: Apart from tumor recurrence, localizations, intra-operative blood transfusion and cardiovascular diseases are independent risk factors for the Pop. We initially found hematological RDW-SD and NLR are also important predictors.

OBJECTIVES: A randomized controlled study was conducted with 422 homeless, stimulant-using gay/bisexual (G/B) men and 29 transgender women (n = 451) to assess two community-based interventions to reduce substance abuse and improve health: (a) a nurse case-managed program combined with contingency management (NCM + CM) versus (b) standard education plus contingency management (SE + CM). STUDY DESIGN: Hypotheses tested included: a) completion of hepatitis A/B vaccination series; b) reduction in stimulant use; and c) reduction in number of sexual partners. METHODS: A deconstructive cost analysis approach was utilized to capture direct costs associated with the delivery of both interventions. Based on an analysis of activity logs and staff interviews, specific activities and the time required to complete each were analyzed as follows: a) NCM + CM only; b) SE + CM only; c) time to administer/record vaccines; and d) time to receive and record CM visits. Cost comparison of the interventions included only staffing costs and direct cash expenditures. RESULTS: The study outcomes showed significant over time reductions in all measures of drug use and multiple sex partners, compared to baseline, although no significant between-group differences were detected. Cost analysis favored the simpler SE + CM intervention over the more labor-intensive NCM + CM approach. Because of the high levels of staffing required for the NCM relative to SE, costs associated with it were significantly higher. CONCLUSIONS: Findings suggest that while both intervention strategies were equally effective in achieving desired health outcomes, the brief SE + CM appeared less expensive to deliver.

Objective: To edentify the increased cost, the decreased benefits and effectiveness of hepatitis B vaccine event reported by media in 2013 in China both in Chinese nationwide and in Shenzhen. Methods: The decision analytic-Markov models were constructed. The cohort born in 2013 in nationwide and in Shenzhen were respectively introduced to the models. The vaccination coverage and the rates of antibody to hepatitis B surface antigen were determined as major parameters. The average costs and benefits per case, the effectiveness which included the numbers of hepatitis B virus (HBV) infection and the patients with HBV-related diseases, the average quality-adjusted life years (QALYs) per case were calculated from the medical-care and societal perspectives. The benefit cost ratio (BCR), ratio of the total costs and the net QALYs were as indicators of cost-benefit and cost-effectiveness analysis, respictively. Results: In nationwide, the BCRs decreased from 9.10 and 8.58 to 2.48 and 2.43, respectively, because the average costs increased to 6 796.60 yuan (RMB) and 8 451.45 yuan, and average benefits decreased to 6 799.57 yuan and 8 484.41 yuan, respectively, from the medical-care and societal perspectives. In Shenzhen, the BCRs decreased from 16.21 and 14.51 to 3.11 and 3.04 with the average costs of 5 244.88 yuan and 8 937.64 yuan, and average benefits of 5 248.11 yuan and 8 977.27 yuan. Totally, the increase of 2.1314 million and 181 hundreds of the HBV infectors occurred for the event in nationwide and in Shenzhen, respectively. Of all the infectors increased the most, the numbers of acute and chronic hepatitis B were 1 904 hundreds and 807 hundreds in nationwide, 794 and 395 in Shenzhen, espectively. The decreases of average QALY per case were 0.119 8 in nationwide and 0.090 6 in Shenzhen. The costs per averted a QALY increased from 6 231.90 yuan to 22 883.51 yuan in nationwide, from 3 567.25 yuan to 1 8571.49 yuan in Shenzhen (for medical-care perspective), from 8 252.79 yuan and 6 807.45 yuan to 29 091.92 yuan and 32 553.60 yuan (for societal perspective). Conclusion: The hepatitis B vaccine event reported by media in 2013 in China caused the costs increased, both benefits and the economic values obviously decreased.

Ras association domain family member 5 (RASSF5), a member of the Ras association domain family, induces cell apoptosis by phosphorylating FOXO3a, which triggers target gene BIM (pro-apoptotic factor) activation. MiR-214 is overexpressed in oral cancer tissue, indicating its possible involvement in oral cancer pathogenesis. Bioinformatics analysis has revealed a complimentary sequence between miR-214 and the 3'-UTR of RASSF5 mRNA. However, whether miR-124 regulates RASSF5 in oral cancer remains poorly understood. We aimed to investigate the role of miR-214 in RASSF5 expression regulation in oral cancer. Tumor and paracarcinoma tissues were obtained from 48 oral cancer patients to examine miR-214 and RASSF5 expression. The relationship between miR-214 and RASSF5 was investigated by dual luciferase reporter gene assay. Oral cancer KB cells were cultured in vitro and divided into inhibitor NC, miR-214 inhibitor, Scramble-pMD18, RASSF5-pMD18, and miR-214 inhibitor + RASSF5-pMD18 groups. Caspase 3 activity, cell apoptosis, and total protein expression were measured by spectrophotometry, flow cytometry, and western blot, respectively. MiR-214 expression was significantly increased, while that of RASSF5 decreased in oral cancer tumor tissues compared to paracarcinoma tissues. Luciferase assay showed that miR-214 suppressed RASSF5 expression by targeting its 3'-UTR. Down-regulation of miR-214 and/or enhancement of RASSF5 expression markedly increased FOXO3a phosphorylation, BIM expression, caspase 3 activity, and apoptosis. In conclusion, miR-214 expression was elevated and RASSF5 was down-regulated in oral cancer. Moreover, miR-214 regulated KB cell apoptosis through targeted inhibition of RASSF5 expression, FOXO3a phosphorylation, and BIM expression, suggesting its possible application as a novel therapeutic oral cancer target.

STUDY DESIGN: This is a randomized controlled prospective trial with two parallel groups. OBJECTIVES: The objective of this study was to determine whether early application of tail nerve electrical stimulation (TANES)-induced walking training can improve the locomotor function. SETTING: This study was conducted in SCS Research Center in Colorado, USA. METHODS: A contusion injury to spinal cord T10 was produced using the New York University impactor device with a 25 -mm height setting in female, adult Long-Evans rats. Injured rats were randomly divided into two groups (n=12 per group). One group was subjected to TANES-induced walking training 2 weeks post injury, and the other group, as control, received no TANES-induced walking training. Restorations of behavior and conduction were assessed using the Basso, Beattie and Bresnahan open-field rating scale, horizontal ladder rung walking test and electrophysiological test (Hoffmann reflex). RESULTS: Early application of TANES-induced walking training significantly improved the recovery of locomotor function and benefited the restoration of Hoffmann reflex. CONCLUSION: TANES-induced walking training is a useful method to promote locomotor recovery in rats with spinal cord injury.

OBJECTIVE: To explore the expression level and location of hypoxia-inducible factor 1α (HIF-1α) in gastric cancer (GC) tissues and their relationship with clinicopathological features and clinical outcomes. METHODS: From July to September 2015, 27 pairs of fresh paired GC tissues and adjacent normal tissues were gathered from the Eighth Department of General Surgery of the First Affiliated Hospital of Anhui Medical University. Quantitative real-time PCR (qRT-PCR) and Western blot were performed to detect the expression of HIF-1α mRNA and protein in these tissues. A total of 191 GC tissues and 46 randomly selected adjacent normal gastric tissues were consecutively collected between December 2006 and September 2008 from Department of General Surgery of the same hospital. Immunohistochemistry were performed on them to detect the expression of HIF-1α and CD34[described in terms of microvessel density (MVD)], and correlation of different locations of HIF-1α (in cytoplasm or nucleus) with MVD, clinicopathological features, and clinical prognosis was analyzed. RESULTS: The average relative expression level of HIF-1α mRNA in GC tissues (0.625±0.170) was significantly higher than in normal adjacent tissues (0.218±0.036, t=2.336, P=0.023) by qRT-PCR. From the results of Western blot, the expression level of HIF-1α protein increased in GC tissues compared with its corresponding normal tissues. Immunohistochemistry results revealed that positive HIF-1α staining was observed in 67.54% GC tissues and 45.65% normal tissues, with significant difference (P=0.006). And 35.08% in GC and 45.65% in normal tissues were cytoplasmic positive (P=0.138); while 37.17% in GC and only 2.17% in normal tissues were nuclear positive, with significant difference (P<0.001). High differentiation group and TNM clinical early stage (â + â ¡) group had significantly higher cytoplasmic HIF-1α expression positive rate compared with low differentiation group (P=0.008) and TNM clinical intermediate-advanced stage (â ¢+ â £) group (P=0.019); whereas low differentiation group had significantly higher nuclear HIF-1α expression positive rate compared with high differentiation group (P=0.043). The mean MVD in the nuclear HIF-1α positive GC group (115.6 ± 7.8) was higher than that in the cytoplasmic HIF-1α positive GC group (93.1±7.5, t=2.077, P=0.040). The median follow-up time was 56(3-81)months. Kaplan-Meier survival analysis and Log-Rank test results showed that nuclear HIF-1α positive patients had a shorter survival time (median 45 months) than cytoplasmic HIF-1α positive patients (median 64 months, P<0.001). Multivariate Cox regression analysis revealed that differentiation (HR=1.713; 95% CI: 1.019-2.882), depth of invasion (tumor stage, HR=6.137; 95% CI: 1.832-20.556) and lymph node metastasis (HR=2.788; 95% CI: 1.313-5.920) were independent prognostic factors for GC (all P<0.05). CONCLUSION: Different location of HIF-1α protein may be realted to the tumorigenesis and progression of GC, and may become a potential prognostic indicator of GC.

BACKGROUND: Sleep fragmentation (SF) increases food intake and the risk of obesity, and recruits macrophages to visceral white adipose tissue (VWAT) promoting tissue inflammation and insulin resistance. Administration of resveratrol (Resv) has been associated with significant improvements in high-fat diet-induced obesity, inflammation and insulin resistance. METHODS: Male mice were subjected to SF or sleep control conditions for 8 weeks, and treated with either Resv or vehicle (Veh). Fasting plasma levels of glucose, insulin and leptin were obtained and VWAT insulin sensitivity tests were performed (phosphorylated AKT/total AKT), along with flow-cytometric assessments for VWAT macrophages (M1 and M2) and T-cell lymphocytes (CD4+, CD8+ and T regulatory cell (Treg)). RESULTS: SF-Veh and SF-Resv mice showed increased food consumption and weight gain. However, although SF-Veh mice exhibited increased fasting insulin and leptin levels, and reduced VWAT p-AKT/AKT responses to insulin, such alterations were abrogated in SF-Resv-treated mice. Increases in M1, reduced M2 counts and increased tumor necrosis factor-α release emerged in SF-Veh macrophages compared with all other three groups. Similarly, increased CD8+ and reduced Treg lymphocyte counts were apparent in SF-Veh. CONCLUSIONS: Resveratrol does not reverse the SF-induced increases in food intake and weight gain, but markedly attenuates VWAT inflammation and insulin resistance, thereby providing a potentially useful adjunctive therapy in the context of sleep disorders manifesting metabolic morbidity.
