ABSTRACT

Objective@#The scientific community knows little about the long-term influence of coronavirus disease 2019 (COVID-19) on olfactory dysfunction (OD). With the COVID-19 pandemic ongoing worldwide, the risk of imported cases remains high. In China, it is necessary to understand OD in imported cases.@*Methods@#A prospective follow-up design was adopted. A total of 11 self-reported patients with COVID-19 and OD from Xi'an No. 8 Hospital were followed between August 19, 2021, and December 12, 2021. Demographics, clinical characteristics, laboratory and radiological findings, and treatment outcomes were analyzed at admission. We surveyed the patients via telephone for recurrence and sequelae at the 1-, 6-, and 12-month follow-up.@*Results@#Eleven patients with OD were enrolled; of these, 54.5% (6/11) had hyposmia and 45.5% (5/11) had anosmia. 63.6% (7/11) reported OD before or on the day of admission as their initial symptom; of these, 42.9% (3/7) described OD as the only symptom. All patients in the study received combined treatment with traditional Chinese medicine and Western medicine, and 72.7% (8/11) had partially or fully recovered at discharge. In terms of OD recovery at the 12-month follow-up, 45.5% (5/11) reported at least one sequela, 81.8% (9/11) had recovered completely, 18.2% (2/11) had recovered partially, and there were no recurrent cases.@*Conclusions@#Our data revealed that OD frequently presented as the initial or even the only symptom among imported cases. Most OD improvements occurred in the first 2 weeks after onset, and patients with COVID-19 and OD had favorable treatment outcomes during long-term follow-up. A better understanding of the pathogenesis and appropriate treatment of OD is needed to guide clinicians in the care of these patients.

ABSTRACT

Objective:To analyze current situation of hospice care in Jinshan District of Shanghai and provide recommendations for development of hospice care. Methods:This cross-sectional study included 8 hospice care institutions, their health staff and 316 patients during May-August, 2019. Results were analyzed by quantitative and qualitative methods. Results:There had 80 approved beds in Jinshan District, but only 53 beds were used for 189 inpatients in 2017. Hospice care institutions received financial supports from district government at the construction stage, but relied on their own for daily operation costs. The motivation of health staff to work in hospice care was not strong. Among the hospice care workers, 18% had no certification for hospice care, and only 5% of them had senior professional titles. Continued education for health workers in hospice care was weak and the workers were under heavy stress. Conclusion:The potential needs for hospice care were unmet while hospice care was under-utilization in Jinshan District. The development of hospice care was unbalanced, and the health workers lacked motivation. The resources of hospice care need to be strengthened.

ABSTRACT

BACKGROUND@#Inflammatory breast cancer (IBC) is an aggressive type of cancer with poor prognosis and outcomes. This study aimed to investigate clinicopathological features, molecular characteristics, and treatments among Chinese patients diagnosed with IBC.@*METHODS@#We collected data of 95 patients with IBC who were treated by members of the Chinese Society of Breast Surgery, from January 2017 to December 2018. The data, including demographic characteristics, pathological findings, surgical methods, systemic treatment plans, and follow-up, were obtained using a uniform electronic questionnaire. The clinicopathological features of different molecular types in patients without distant metastases were compared using the Kruskal-Wallis (H) test followed by post hoc analyses.@*RESULTS@#Lymph node metastasis was noted in 75.8% of all patients, while distant metastasis was noted in 21.4%. Pathological findings indicated invasive ductal and lobular carcinomas in 86.8% and 5.3% of cases, respectively. Hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) (41.5%) and HR-/HER2+ (20.1%) were the most common biologic subtypes, followed by HR+/HER2+ (19.1%) and HR-/HER2- (19.1%). Stage III IBC was treated via pre-operative neoadjuvant chemotherapy in 87.7% of the cases, predominantly using anthracycline and taxanes. A total of 91.9% of patients underwent surgical treatment. Among them, 77.0% of the patients underwent modified radical mastectomy, 8.1% of whom also underwent immediate breast reconstruction. The Kruskal-Wallis test revealed that the efficacy of chemotherapy significantly differed among those with HR+/HER2- and HR-/HER2- tumors (adjusted P = 0.008), and Ki-67 expression significantly differed in HR-/HER2+ and HR+/HER2+ molecular subtypes (adjusted P = 0.008).@*CONCLUSION@#Our study provides novel insight into clinicopathological characteristics and treatment status among patients with IBC in China, and might provide a direction and basis for further studies.@*TRIAL REGISTRATION@#chictr.org.cn, No. ChiCTR1900027179; http://www.chictr.org.cn/showprojen.aspx?proj=45030.

ABSTRACT

OBJECTIVE@#Epstein-Barr virus associated gastric cancer (EBVaGC) is different from the traditional gastric cancer (Epstein-Barr virus non-associated gastric cancer, EBVnGC), and has unique clinicopathological features. This study investigated the largest single center cancer series so as to establish the clinicopathological and molecular characteristics of EBVaGC in China.@*METHODS@#A retrospective analysis was conducted on EBVaGC and EBVnGC patients diagnosed at Peking University Cancer Hospital from 2003 to 2018 by comparing their clinicopathological features and prognosis. The gastric cancer (GC) dataset of public database was analyzed to obtain differentially expressed genes. The expression of important genes and their association with prognosis of GC were verified in GC tissues from our hospital.@*RESULTS@#In this study, 3 241 GC patients were included, and a total of 163 EBVaGC (5.0%) patients were identified. Compared with EBVnGC, EBVaGC was higher in male and younger patients, and positively associated with remnant GC, poorly differentiated adenocarcinoma, and mixed type GC. EBVaGC was inversely related to lymph node metastasis. The 5-year survival rate of EBVnGC and EBVaGC was 59.6% and 63.2% respectively (P<0.05). In order to explore molecular features of EBVaGC, the Cancer Genome Atlas (TCGA) dataset was analyzed (n=240), and 7 404 significant differentially expressed genes were obtained, involving cell proliferation, apoptosis, invasion and metastasis. The down-regulated invasion/metastasis gene SALL4 and the up-regulated immune checkpoint gene PD-L1 were important molecular features of EBVaGC. Validation of these two genes in large GC series showed that the majority of the EBVaGC was SALL4 negative (1/92, 1.1%, lower than EBVnGC, 303/1 727, 17.5%), and that PD-L1 was mostly positive in EBVaGC (81/110, 73.6%, higher than EBVnGC, 649/2 350, 27.6%). GC patients with SALL4 negative and PD-L1 positive were often associated with better prognosis.@*CONCLUSION@#EBVaGC is a unique subtype of GC with less metastasis and a good prognosis. It also has a distinct molecular background. The down-regulation of invasion/metastasis gene SALL4 and up-regulation of immune checkpoint gene PD-L1 are important molecular features.

ABSTRACT

AIM:To investigate the effects of carbon monoxide-releasing molecule-2 (CORM-2) on intestinal barrier injury in cardiopulmonary resuscitation (CPR) rats.METHODS:The model of intestinal ischemia-reperfusion injury after cardiac arrest (CA) -CPR was established by intravenous injection of potassium chloride (4℃) combined with asphyxiation for 4 min, followed by artificial chest compression for 3 min.The SD rats (n=32) were randomly divided into 4 groups:sham group, CPR group, CORM-2 group and inactivated CORM-2 (i CORM-2) group, with 8 rats in each group.The rats in sham group were instrumented with catheter without experiencing cardiac arrest or CPR.The rats in other groups were inserted with the catheters and underwent CA-CPR.In CORM-2 group and i CORM-2 group, the rats were given CORM-2 at 4 mg/kg and i CORM-2 at 4 mg/kg by intraperitoneal injection at 12 h before CA-CPR.In sham group and CPR group, the rats were administrated with an equivalent volume of vehicle.The hemodynamic data were monitored for 4 h after resuscitation (or catheterization) in each group.The ileum tissues and blood samples were harvested at 4 h after resuscitation (or catheterization).Histopathological changes and ultrastructure of the ileum were observed by HE staining and transmission electron microscopy.The levels of intestinal fatty acid binding protein (I-FABP) in the blood was measured by ELISA.The protein expression of claudin-3, occludin, ZO-1 and proinflammatory factor tumor necrosis factor-α (TNF-α) in the ileum tissues was determined by Western blot.RESULTS:No significant difference of mean arterial pressure (MAP) immediately after catheterization between sham group and resuscitation groups was observed.In CPR group, CORM-2 group and i CORM-2 group, the MAP at each time point after resuscitation was obviously lower than that immediately after catheterization and this phenomenon continued until 4 h after resuscitation (P<0.05).The MAP at each time point after resuscitation in all resuscitation groups was prominently lower than that at the same time points in sham group (P<0.05).The MAP at each time point after resuscitation in CORM-2 group was higher than that in CPR group and i CORM-2 group (P<0.05).The histopathological changes and ultrastructural damage of ileum mucosa in CPR group were obvious.In CORM-2 group, the histopathological changes and ultrastructural integrity of ileum mucosa were significantly better than those in other resuscitation groups.Compared with sham group, the level of I-FABP in CPR group and i CORM-2 group was significantly increased (P<0.05).The level of I-FABP in CORM-2 group showed no statistically significant difference as compared with sham group.The level of I-FABP in CORM-2 group was notably lower than that in CPR group and i CORM-2 group (P<0.05).Compared with sham group, the expression of claudin-3, occludin and ZO-1 in ileum tissues was decreased in CPR group and i CORM-2 group (P<0.05) , but in CORM-2 group, only the expression of claudin-3 and ZO-1 were decreased (P<0.05).The levels of the above proteins in CORM-2 group were higher than those in CPR group and i CORM-2 group (P<0.05).Compared with sham group, the expression of TNF-αin ileum tissues was increased in CPR group and i CORM-2 group (P<0.05) , and the level of TNF-αin CORM-2 group showed no statistically significant difference as compared with sham group.The protein level of TNF-αin CORM-2 group was lower than that in CPR group and i CORM-2 group (P<0.05).CONCLUSION:Cardiac arrest-cardiopulmonary resuscitation causes severe damage of intestinal mechanical barrier in rats.CORM-2 may protect the intestinal barrier integrity in cardiopulmonary resuscitation rats by up-regulating the expression of tight junction proteins in the intestinal epithelium.

ABSTRACT

Phenolic compounds have multiple bioactivities, such as anti-oxidant, anti-tumor, anti-bacterial, and anti-inflammatory activities. Recent literatures have demonstrated that flavonoids have a significant anti-anxiety effect on the central nervous system. In addition, studies showed that flavonoids acted as pro-drugs, which were transformed into smaller phenols through intestinal microflora. The small phenolic metabolites were crucial for the anxiolytic effects of these flavonoids, indicating that natural small-molecule phenols(NSMP) generally have anxiolytic activities. In this paper, the supporting evidences (before June 2016) from SciFinder database have been summarized. Furthermore, NSMPs were classified according to chemical structures; their anxiolytic effects, mechanisms, and the structure-activity relationships were also discussed.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the relationship between the clinical and pathological findings in IgA nephropathy with or without IgG deposition in the glomerular mesangial area.</p><p><b>METHODS</b>The data were collected from 122 patients with a diagnosis of IgA nephropathy by renal biopsy in the Third Affiliated Hospital of Southern Medical University between November, 2009 and February, 2016. All the samples were examined by light microscopy, immunofluorescence and electron microscopy. According to the results of immunofluorescence assay, the patients were divided into IgA group (n=63) and IgA-IgG group (n=59). The pathological classification of IgA nephropathy was analyzed according to Oxford classification and Lee's classification. The clinical and pathological findings were compared between the two groups.</p><p><b>RESULTS</b>Compared with the patients with IgA nephropathy but without IgG deposition, patients with IgA nephropathy with IgG deposition had higher serum creatinine, higher 24-h urine protein, higher blood uric acid, higher triglyceride levels (P<0.05) and lower eGFR (P<0.05); more of these patients were in Lee's grade IV-V, had renal tubular atrophy and/or interstitial fibrosis, and had MEST scores more than 3 (P<0.05).</p><p><b>CONCLUSION</b>Patients with IgA nephropathy with IgG deposition in the glomerular mesangial have severer clinical symptoms and more serious pathological changes. Measures should be taken to control IgG deposition in patients with IgA nephropathy to delay the progress of the disease.</p>

ABSTRACT

Objective: To assess if prophylactic thoracic duct ligation during oesophagectomy influences the absorptive function of oesophageal cancer patients


Study Design: Randomized controlled trial


Place and Duration of Study: Department of Thoracic Surgery, Tai'an City Central Hospital, Tai'an, from August 2014 to December 2015


Methodology: Based on the management of the thoracic duct during oesophagectomy, 60 patients were randomized into two groups. D-xylose absorption test was used to evaluate the absorptive function. The two-independent-samples t-test was employed for statistical analysis with statistical significance at p < 0.05


Results: The serum D-xylose concentration of ligation-group was significantly lower than that of no-ligation group on the first day after operation, [t=2.82, p=0.0066]. However, there was no significant differences between them even before operation [t=1.34, p=0.1849]


Conclusion: Ligation of the thoracic duct during oesophagectomy immediately affected the absorption of D-xylose, which may lead to malabsorption in the long run

ABSTRACT

<p><b>BACKGROUND</b>Despite its high prevalence, morbidity, and mortality, sepsis-associated encephalopathy (SAE) is still poorly understood. The aim of this prospective and observational study was to investigate the clinical significance of calcium-binding protein A8 (S100A8) in serum and tumor necrosis factor receptor-associated factor 6 (TRAF6) in peripheral blood mononuclear cells (PBMCs) in diagnosing SAE and predicting its prognosis.</p><p><b>METHODS</b>Data of septic patients were collected within 24 h after Intensive Care Unit admission from July 2014 to March 2015. Healthy medical personnel served as the control group. SAE was defined as cerebral dysfunction in the presence of sepsis that fulfilled the exclusion criteria. The biochemical indicators, Glasgow Coma Scale, Acute Physiology and Chronic Health Evaluation score II, TRAF6 in PBMC, serum S100A8, S100β, and neuron-specific enolase were evaluated in SAE patients afresh. TRAF6 and S100A8 were also measured in the control group.</p><p><b>RESULTS</b>Of the 57 enrolled patients, 29 were diagnosed with SAE. The S100A8 and TRAF6 concentrations in SAE patients were both significantly higher than that in no-encephalopathy (NE) patients, and higher in NE than that in controls (3.74 ± 3.13 vs. 1.08 ± 0.75 vs. 0.37 ± 0.14 ng/ml, P < 0.01; 3.18 ± 1.55 vs. 1.02 ± 0.63 vs. 0.47 ± 0.10, P < 0.01). S100A8 levels of 1.93 ng/ml were diagnostic of SAE with 92.90% specificity and 69.00% sensitivity in the receiver operating characteristic (ROC) curve, and the area under the curve was 0.86 (95% confidence interval [CI]: 0.76-0.95). TRAF6-relative levels of 1.44 were diagnostic of SAE with 85.70% specificity and 86.20% sensitivity, and the area under the curve was 0.94 (95% CI: 0.88-0.99). In addition, S100A8 levels of 2.41 ng/ml predicted 28-day mortality of SAE with 90.00% specificity and 73.70% sensitivity in the ROC curve, and the area under the curve was 0.88. TRAF6 relative levels of 2.94 predicted 28-day mortality of SAE with 80.00% specificity and 68.40% sensitivity, and the area under the curve was 0.77. Compared with TRAF6, the specificity of serum S100A8 in diagnosing SAE and predicting mortality was higher, although the sensitivity was low. In contrast, the TRAF6 had higher sensitivity for diagnosis.</p><p><b>CONCLUSIONS</b>Peripheral blood levels of S100A8 and TRAF6 in SAE patients were elevated and might be related to the severity of SAE and predict the outcome of SAE. The efficacy and specificity of S100A8 for SAE diagnosis were superior, despite its weak sensitivity. S100A8 might be a better biomarker for diagnosis of SAE and predicting prognosis.</p>

ABSTRACT

<p><b>BACKGROUND</b>Open reduction and internal fixation with plate and screws are the gold standard for the surgical treatment of humeral shaft fractures, this study was to compare the mechanical properties of anteromedial, anterolateral, and posterior plating for humeral shaft fractures.</p><p><b>METHODS</b>A distal third humeral shaft fracture model was constructed using fourth-generation sawbones (#3404, composite bone). A total of 24 sawbones with a distal third humeral shaft fracture was randomly divided into three Groups: A, B, and C (n = 8 in each group) for anteromedial, anterolateral, and posterior plating, respectively. All sawbones were subjected to horizontal torsional fatigue tests, horizontal torsional and axial compressive fatigue tests, four-point bending fatigue tests in anteroposterior (AP) and mediolateral (ML) directions and horizontal torsional destructive tests.</p><p><b>RESULTS</b>In the horizontal torsional fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 6.12°, 6.53°, and 6.81°. In horizontal torsional and axial compressive fatigue tests, the mean torsional angle amplitude in Groups A, B, and C were 5.66°, 5.67°, and 6.36°. The mean plate displacement amplitude was 0.05 mm, 0.08 mm, and 0.10 mm. Group A was smaller than Group C (P < 0.05). In AP four-point bending fatigue tests, the mean plate displacement amplitude was 0.16 mm, 0.13 mm, and 0.20 mm. Group B was smaller than Group C (P < 0.05). In ML four-point bending fatigue tests, the mean plate displacement amplitude were 0.16 mm, 0.19 mm, and 0.17 mm. In horizontal torsional destructive tests, the mean torsional rigidity in Groups A, B, and C was 0.82, 0.75, and 0.76 N·m/deg. The yielding torsional angle was 24.50°, 25.70°, and 23.86°. The mean yielding torque was 18.46, 18.05, and 16.83 N·m, respectively.</p><p><b>CONCLUSIONS</b>Anteromedial plating was superior to anterolateral or posterior plating in all mechanical tests except in AP four-point bending fatigue tests compared to the anterolateral plating group. We can suggest that anteromedial plating is a clinically safe and effective way for humeral shaft fractures.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To explore the relationship between waist-to-hip ratio (WHR) and chronic kidney disease (CKD) in non-diabetic subjects and compare the difference between male and female subjects.</p><p><b>METHODS</b>We performed a cross-sectional survey among 2142 community-based southern Chinese participants without diabetes from June to October 2012. We divided all the participants into 4 groups according to the gender-specific quartiles of WHR. Logistic regression models were used to explore the associations of WHR with CKD in these subjects.</p><p><b>RESULTS</b>In the unadjusted model, WHR was significantly associated with CKD in women (OR=7.29, 95% CI: 3.56-16.32, P<0.001), and the association was still significant (OR=6.13, 95% CI: 2.56-15.20, P=0.003 ) after adjustment for the potential confounders (including age, history of hypertension, coronary heart disease, current smoker, physical inactivity, education level, systolic blood pressure, diastolic blood pressure, serum triglyceride, serum high density lipoprotein, blood glucose, and BMI). The odds ratio (OR) for having CKD in the highest versus lowest quartile of WHR levels was 2.44 (95% CI: 0.98-4.97, P=0.103) in men in the unadjusted model.</p><p><b>CONCLUSION</b>WHR levels are associated with CKD in non-diabetic women but not in non-diabetic male subjects.</p>

ABSTRACT

<p><b>OBJECTIVE</b>This review examines the evidence that deep brain stimulation (DBS) has extensive impact on nonmotor symptoms (NMSs) of patients with Parkinson's disease (PD).</p><p><b>DATA SOURCES</b>We retrieved information from the PubMed database up to September, 2015, using various search terms and their combinations including PD, NMSs, DBS, globus pallidus internus (GPi), subthalamic nucleus (STN), and ventral intermediate thalamic nucleus.</p><p><b>STUDY SELECTION</b>We included data from peer-reviewed journals on impacts of DBS on neuropsychological profiles, sensory function, autonomic symptoms, weight changes, and sleep disturbances. For psychological symptoms and cognitive impairment, we tried to use more reliable proofs: Random, control, multicenter, large sample sizes, and long period follow-up clinical studies. We categorized the NMSs into four groups: those that would improve definitively following DBS; those that are not significantly affected by DBS; those that remain controversial on their surgical benefit; and those that can be worsened by DBS.</p><p><b>RESULTS</b>In general, it seems to be an overall beneficial effect of DBS on NMSs, such as sensory, sleep, gastrointestinal, sweating, cardiovascular, odor, urological symptoms, and sexual dysfunction, GPi-DBS may produce similar results; Both STN and Gpi-DBS are safe with regard to cognition and psychology over long-term follow-up, though verbal fluency decline is related to DBS; The impact of DBS on behavioral addictions and dysphagia is still uncertain.</p><p><b>CONCLUSIONS</b>As the motor effects of STN-DBS and GPi-DBS are similar, NMSs may determine the target choice in surgery of future patients.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the influences of mobile phone radiation on the quality and DNA methylation of human sperm in vitro.</p><p><b>METHODS</b>According to the fifth edition of the WHO Laboratory Manual for the Examination and Processing of Human Semen, we randomly selected 97 male volunteers with normal semen parameters and divided each semen sample from the subjects into two equal parts, one exposed to mobile phone radiation at 1950 M Hz, SAR3. 0 W/kg for 3 hours while the other left untreated as the control. We obtained routine semen parameters as well as the acrosomal reaction ability, apoptosis and DNA methylation of sperm, and compared them between the two groups.</p><p><b>RESULTS</b>Compared with the control, the radiation group showed significantly decreased progressive sperm motility ([36.64 ± 16.93] vs [27.56 ± 16.92]%, P < 0.01) and sperm viability ([63.72 ± 16.35] vs [54.31 ± 17.35]%, P < 0.01) and increased sperm head defects ([69.92 ± 4.46] vs [71.17 ± 4.89]%, P < 0.05), but no significant differences in sperm acrosomal reaction ([66.20 ± 6.75] vs [64.50 ± 3.47]%, P > 0.05). The early apoptosis rate of sperm cells was remarkably higher in the radiation group ([6.89 ± 9.84]%) than in the control ([4.44 ± 5.89]%) (P < 0.05). However, no statistically significant differences were found between the control and radiation groups in the DNA methylation patterns of the paternal imprinting gene H19 ICR ([0.60 ± 0.02] vs [1.40 ± 0.03]%, P > 0.05) or the maternal imprinting gene KvDMR1 ([0.00 ± 0.00] vs [1.80 ± 0.031%, P > 0.05).</p><p><b>CONCLUSION</b>Mobile phone radiation reduces the progressive motility and viability of human sperm and increases sperm head defects and early apoptosis of sperm cells.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of the magnesium isoglycyrrhizinate plus nucleoside analogues (MGL + NA) combination therapy in patients with chronic hepatitis B using a meta-analysis approach.</p><p><b>METHODS</b>The Chinese Biochemical literature on Disc (CBMDisc) and the Chinese Scientific Journal database, CNKI, were searched for randomized controlled trials (RCTs) of MGL+NA in patients with chronic hepatitis B published between 1995 and 2013. Data related to treatment type (combination therapy vs. mono-therapy) and outcome (markers of efficacy and safety, including levels of hepatitis B virus (HBV) DNA, hepatitis B e antigen (HBeAg), alanine aminotransferase (ALT) and aspartate aminotransferase (AST)). Weighted mean differences (WMD) were calculated and the Peto method was used to determine the relative risk (RR), both with 95% confidence intervals (CIs).</p><p><b>RESULTS</b>Meta-analysis of the six included RCTs of MGL + NA, representing a 704 patients with chronic hepatitis B, showed WMDs for ALT of -12.98 (95% CI: -18.24 to -7.71, P less than 0.01) and for AST of -9.49 (95% CI: -14.53 to -4.45, P = 0.0002) and RRs for HBeAg of 1.79 (95% CI: 1.17 to 2.76, P = 0.008) and for HBV DNA of 1.35 (95% CI: 1.05 to 1.74, P = 0.02). The therapeutic efficacy of MGL+NA combination therapy was better than that of NA mono-therapy (P less than 0.01).</p><p><b>CONCLUSION</b>For patients with chronic hepatitis B, MGL combination therapy may enhance the antiviral efficacy of NA treatment and help to improve liver function during treatment.</p>

ABSTRACT

To investigate the prevalence and distribution of metabolic syndrome [MetS] and the impact of exercise, smoking, and educational level on the risk of MetS in a southern Chinese population. A cross-sectional study was conducted in Zhuhai City, China from June to August 2012. Data on exercise, smoking, and educational level, anthropometric parameters, blood pressure, lipid, and glucose levels were collected. The prevalence of MetS [as defined by the International Diabetes Federation] was determined. Data necessary to evaluate MetS, the socio-economic characteristics, and lifestyle were obtained for 4645 subjects aged 18-75 years old. A total of 19.8% of the participants had MetS. The adjusted odds of having MetS were lower among males [adjusted odds: 0.75; 95% confidence interval [CI]: 0.57-1.01] compared with females. Those participants who currently smoked had a higher risk of developing MetS compared with non-smokers [adjusted odds: 1.61; 95% CI: 1.13-2.50]. Those who had no physical exercise had a higher risk of developing MetS compared with those who physically exercised more than 60 minutes/day [adjusted odds: 1.51; 95% CI: 1.12-2.23;]. Compared with those with no education, every category of attained educational level had a lower risk of developing MetS [P<0.001]. The findings in this study revealed that current smokers had a greater risk of developing MetS compared with non-smokers. Increased physical activity and higher levels of education attained served as protective factors for the population

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the plasma amino acid spectrum in infants more than 1-year-old with neonatal intrahepatic cholestasis caused by citrin deficiency (NICCD) in order to identify potential diagnostic markers of NICCD.</p><p><b>METHODS</b>Infants less than 1 year of age who had been referred to our hospital for investigation of suspected conjugated hyperbilirubinemia between June 2003 and June 2009 were eligible for enrollment. A total of 182 infants were enrolled and divided into three groups: infants diagnosed with NICCD (n = 24), according to gene testing and/or western blotting results; infants diagnosed with biliary atresia (BA; n = 20), according to intra-operative cholangiography findings; and infants diagnosed with idiopathic neonatal intrahepatic hepatitis (INH; n = 138), according to exclusionary findings for diseases affecting the extrahepatic biliary system and no positive serology results to indicate infections with hepatitis B, C, A or E, toxoplasmosis, rubella, herpes simplex, human immunodeficiency virus-1, or syphilis. The plasma amino acid spectrum of each infant was analyzed by tandem mass spectrometry (MS/MS). The concentrations of 18 amino acids, as well as the ratio of each amino acid to total amino acids, were compared among the three groups. Selected ratios of amino acids were analyzed by receiver operating characteristic (ROC) curve analysis.</p><p><b>RESULTS</b>Compared with the BA and INH groups, the NICCD group had significantly lower levels of alanine (Ala; 175.7 and 205.7 vs. 136.3 mumol/L, P = 0.0001), aspartic acid (Asp; 47.5 and 43.1 vs. 31.55 mumol/L, P = 0.0041), glutamic acid (Glu; 276.16 and 263.24 vs. 175.71 mumol/L, P = 0.0075) and tryptophan (Trp; 41.90 and 47.97 vs. 28.51 mumol/L, P = 0.0003), but significantly higher levels of methionine (Met; 28.24 and 29.35 vs. 71.40 mumol/L, P = 0.0390), tyrosine (Tyr; 55.8 and 57.02 vs. 116.81 mumol/L, P = 0.0072) and citrulline (Cit; 15.09 and 15.65 vs. 97.42 mumol/L, P = 0.0001). The ratio of each amino acid to total amino acids showed the same trends for the NICCD group. The calculated areas under the ROC curves of the ratios of Cit, Tyr, and Met to the total amino acids were 0.874 (95% CI: 0.752 - 0.996), 0.814 (95% CI: 0.706 - 0.923), and 0.705 (95% CI: 0.535 - 0.875) respectively. The calculated area under the ROC curve of the ratio of Cit to Ala was 0.893 (95% CI: 0.781 - 1.005), and when the cut-off value of the ratio of Cit to Ala was 0.14 for diagnosis of NICCD, the sensitivity and specificity were 75% and 95% respectively.</p><p><b>CONCLUSION</b>The plasma amino acid spectrum may represent a diagnostic indicator for NICCD, particularly the ratio of Cit to Ala.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To detect the expression of S100A6 in gastric cancer, and to investigate the regulation mechanism of S100A6 in invasion and metastasis of gastric cancer.</p><p><b>METHODS</b>Expression of S100A6 protein in gastric cancer specimens, tissue adjacent to cancer, liver and lymph node metastasis tissue specimens was detected by immunohistochemical staining in 166 patients with gastric cancer from January 1995 to December 2001. Their association with clinicopathological factors was analyzed. Chromatin Immunoprecipitation-chip was used to detect the downstream factors potentially regulated by S100A6 in gastric cancer cell lines KATO3. S100A6 gene was transfected into gastric cancer cell line AGS, and cell invasion experiment and real time Q-polymerase chain reaction(RT Q-PCR) were used to detect the cell invasive ability and the mRNA expression of invasion-related factors (CDK5 and FLJ12438) in transfection group, negative control group and blank control group, respectively.</p><p><b>RESULTS</b>Low expression of S100A6 protein was found in cytoplasm of peritumoral tissues. In gastric cancer, liver and lymph node metastasis tissues, S100A6 protein expression was up-regulated in cytoplasm and (or) nuclei, especially in the tumor cells of invasive edge. The expression rates of gastric cancer, liver and lymph node metastasis tissues were 67.5%(112/166), 92.9%(26/28) and 100% (30/30) respectively. The high expression of S100A6 was associated with tumor local invasion, lymph node metastasis, cancer embolus, distant metastasis and TNM stages(all P<0.05). The transmembrane cell number was 31.3±5.5 in the S100A6 transfection group, significantly higher than that in negative control group (7.7±1.5) and blank control group (9.3±2.1)(both P<0.05), indicating an increase of cell invasion after S100A6 transfection. In transfection group, CDK5 mRNA expression was significantly higher than that in negative control group and blank control group(P<0.05). While FLJ1243 mRNA expression was similar among the three groups(P<0.05).</p><p><b>CONCLUSION</b>S100A6 may affect the malignant biological behavior of gastric cancer cells by regulating the expressions of down-stream invasion-associated factors, such as CDK5.</p>

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the current situation of treatment for acute chemical poisoning in the emergency departments and occupational disease departments of some general hospitals and to provide a basis for improving the ability of general hospital to deal with acute chemical poisoning.</p><p><b>METHODS</b>Four hospitals from Shandong Province, Beijing City, and Shanxi Province, China were selected in the study. They included two first-class hospitals located in the downtown, where the patients with acute chemical poisoning from urban and suburban areas were admitted to the occupational disease departments, and two second-class hospitals located in the suburban area or county, where the patients with acute chemical poisoning from the suburban area were admitted to the emergency departments. A questionnaire survey was conducted in 141 medical workers (51 persons in the emergence department group and 90 persons in the occupational disease department group) that were engaged in the treatment of acute chemical poisoning in the four hospitals; 1999 medical records were analyzed. Individual in-depth interviews, questionnaire investigation, and field observation were used to compare the emergency department group and occupational disease department group in terms of the ability to deal with acute chemical poisoning and the training on treatment for acute chemical poisoning.</p><p><b>RESULTS</b>The emergency department group had significantly higher proportion of pesticide poisoning cases than the occupational disease department group (P<0.01). Thirty-seven of the patients in occupational disease department group died, with a fatality rate of 2.7%, and 14 of the patients in emergence department group died,with a fatality rate of 2.2%, so there was no significant difference between the two groups in this regard (P>0.05). There were significantly more cases treated without emergency plan in the emergency department group than in the occupational disease department group ( 37.3% vs. 10.0%, P <0.0 1). The occupational disease department group had significantly higher score of knowledge about the treatment for acute chemical poisoning than the emergence department group (7.2±1.3 vs. 5.2±0.9, P<0.01 ). There were significantly lower proportions of medical staff who had received training on the knowledge about acute chemical poisoning and on the emergency disposal of acute chemical poisoning in the emergency department group than in the occupational disease department group (P<0.05).</p><p><b>CONCLUSION</b>There is a lack of the knowledge about treatment for acute chemical poisoning and protective measures during treatment among the medical staff in general hospitals, and related training and emergency plan are needed.</p>
