Objective: The relationship between serum uric acid (SUA) levels and glycemic indices, including plasma glucose (FPG), 2-hour postload glucose (2h-PG), and glycated hemoglobin (HbA1c), remains inconclusive. We aimed to explore the associations between glycemic indices and SUA levels in the general Chinese population. Methods: The current study was a cross-sectional analysis using the first follow-up survey data from The China Cardiometabolic Disease and Cancer Cohort Study. A total of 105,922 community-dwelling adults aged ≥ 40 years underwent the oral glucose tolerance test and uric acid assessment. The nonlinear relationships between glycemic indices and SUA levels were explored using generalized additive models. Results: A total of 30,941 men and 62,361 women were eligible for the current analysis. Generalized additive models verified the inverted U-shaped association between glycemic indices and SUA levels, but with different inflection points in men and women. The thresholds for FPG, 2h-PG, and HbA1c for men and women were 6.5/8.0 mmol/L, 11.0/14.0 mmol/L, and 6.1/6.5, respectively (SUA levels increased with increasing glycemic indices before the inflection points and then eventually decreased with further increases in the glycemic indices). Conclusion An inverted U-shaped association was observed between major glycemic indices and uric acid levels in both sexes, while the inflection points were reached earlier in men than in women.

Objective: To explore the effect of perioperative chemotherapy on the prognosis of gastric cancer patients under real-world condition. Methods: A retrospective cohort study was carried out. Real world data of gastric cancer patients receiving perioperative chemotherapy and surgery + adjuvant chemotherapy in 33 domestic hospitals from January 1, 2014 to January 31, 2016 were collected. Inclusion criteria: (1) gastric adenocarcinoma was confirmed by histopathology, and clinical stage was cT2-4aN0-3M0 (AJCC 8th edition); (2) D2 radical gastric cancer surgery was performed; (3) at least one cycle of neoadjuvant chemotherapy (NAC) was completed; (4) at least 4 cycles of adjuvant chemotherapy (AC) [SOX (S-1+oxaliplatin) or CapeOX (capecitabine + oxaliplatin)] were completed. Exclusion criteria: (1) complicated with other malignant tumors; (2) radiotherapy received; (3) patients with incomplete data. The enrolled patients who received neoadjuvant chemotherapy and adjuvant chemotherapy were included in the perioperative chemotherapy group, and those who received only postoperative adjuvant chemotherapy were included in the surgery + adjuvant chemotherapy group. Propensity score matching (PSM) method was used to control selection bias. The primary outcome were overall survival (OS) and progression-free survival (PFS) after PSM. OS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the last effective follow-up or death. PFS was defined as the time from the first neoadjuvant chemotherapy (operation + adjuvant chemotherapy group: from the date of operation) to the first imaging diagnosis of tumor progression or death. The Kaplan-Meier method was used to estimate the survival rate, and the Cox proportional hazards model was used to evaluate the independent effect of perioperative chemo therapy on OS and PFS. Results: 2 045 cases were included, including 1 293 cases in the surgery+adjuvant chemotherapy group and 752 cases in the perioperative chemotherapy group. After PSM, 492 pairs were included in the analysis. There were no statistically significant differences in gender, age, body mass index, tumor stage before treatment, and tumor location between the two groups (all P>0.05). Compared with the surgery + adjuvant chemotherapy group, patients in the perioperative chemotherapy group had higher proportion of total gastrectomy (χ(2)=40.526, P<0.001), smaller maximum tumor diameter (t=3.969, P<0.001), less number of metastatic lymph nodes (t=1.343, P<0.001), lower ratio of vessel invasion (χ(2)=11.897, P=0.001) and nerve invasion (χ(2)=12.338, P<0.001). In the perioperative chemotherapy group and surgery + adjuvant chemotherapy group, 24 cases (4.9%) and 17 cases (3.4%) developed postoperative complications, respectively, and no significant difference was found between two groups (χ(2)=0.815, P=0.367). The median OS of the perioperative chemotherapy group was longer than that of the surgery + adjuvant chemotherapy group (65 months vs. 45 months, HR: 0.74, 95% CI: 0.62-0.89, P=0.001); the median PFS of the perioperative chemotherapy group was also longer than that of the surgery+adjuvant chemotherapy group (56 months vs. 36 months, HR=0.72, 95% CI:0.61-0.85, P<0.001). The forest plot results of subgroup analysis showed that both men and women could benefit from perioperative chemotherapy (all P<0.05); patients over 45 years of age (P<0.05) and with normal body mass (P<0.01) could benefit significantly; patients with cTNM stage II and III presented a trend of benefit or could benefit significantly (P<0.05); patients with signet ring cell carcinoma benefited little (P>0.05); tumors in the gastric body and gastric antrum benefited more significantly (P<0.05). Conclusion: Perioperative chemotherapy can improve the prognosis of gastric cancer patients.

Objective To investigate the prevalence and molecular features of Cryptosporidium in sheep and goats from Anhui Province and neighboring provinces. Methods A total 832 and 781 fresh fecal samples were collected from seven large-scale sheep farms and ten large-scale goat farms in Anhui Province and neighboring provinces of Henan, Jiangsu and Shandong. The prevalence and species of Cryptosporidium were investigated in the fecal samples from the sheep and goats in the study areas using nested PCR assay based on the Cryptosporidium-specific SSU rDNA gene, and the subgenotypes of C. parvum and C. ubiquitum were characterized by amplification and sequencing of the 60 kDa glycoprotein (gp60) gene. Results The overall prevalence of Cryptosporidium was 5.8% (48/832) in sheep and 8.7% (68/781) in goats in Anhui Province and neighboring provinces, respectively. The SSU rDNA gene-based PCR assay identified C. xiaoi and C. ubiquitum in sheep and C. parvum in goats, and subtyping revealed that all C. ubiquitum subgenotypes belonged to XIIa subtype 2 and C. parvum subgenotypes belonged to IIdA19G1. Conclusion The identification of zoonotic C. ubiquitum XIIa subtype 2 and C. parvum subtype IIdA19G1 suggests that sheep and goats may serve as a potential source for human Cryptosporidium infections.

OBJECTIVE: This study aimed to analyze the treatment for mandibular coracoid fractures retrospectively. METHODS: A retrospective study on 37 patients with mandibular coracoid fractures treated at Department of Traumatic and Plastic Surgery, West China Hospital of Stomatology, Sichuan University from January 2010 to December 2015 was conducted. Eleven patients were treated conservatively, and 26 patients underwent surgical restoration and internal fixation. Mouth opening and pain degree were used as indicators to analyze treatment results. RESULTS: The 37 cases of coracoid fractures accounted for 3.18% of the total mandibular fractures. The average age of patients was 38.05 years. Satisfactory results were obtained in both treatments. A considerable change in the degree of mouth opening before and after 6 months was found in the two groups. The pain degree before treatment and 1 day after operation, 1 day and 4 weeks after operation, and 4 weeks and 6 months after operation indicated that the two groups did not significantly differ. However, substantial changes between the two groups were found before treatment and 6 months after operation. CONCLUSIONS Conservative treatment is recommended for patients with linear, temporalis muscle-located, and non-displaced coracoid fractures. Surgical treatment is recommended for patients with large fractures and those with accompanying zygomatic arch and mandible fractures.

Brain magnetic resonance imaging (MRI) of the elderly often reveals white matter changes (WMCs) with substantial variability across individuals.Our study was designed to explore MRI features and site-specific factors of ischemic WMCs.Clinical data of consecutive patients diagnosed with ischemic cerebral vascular disease who had undergone brain MRI were collected and analyzed.Multi-logistic regression analysis comparing patients with mild versus severe WMCs was performed to detect independent associations.Analyses of variance (ANOVAs) were used to detect regionally specific differences in lesions.We found that lesion distribution differed significantly across five cerebral areas,with lesions being predominant in the frontal lobe and parieto-occipital area.To explore WMCs risk factors,after adjusting for gender,diabetes mellitus,and hypertension,only age (P＜0.01),creatinine (P=0.01),alkaline phosphatase (ALP) (P=0.01) and low-density lipoprotein cholesterol (LDL-C) (P=0.03) were found to be independently associated with severe WMCs.Age (P＜0.001) was strongly associated with WMCs in the frontal lobe while hypertension was independently related to lesions in the basal ganglia (P=0.048) or infratentorial area (P=0.016).In conclusion,MRI of WMCs showed that ischemic WMCs occurred mostly in the frontal lobe and parieto-occipital area.The infratentorial area was least affected by WMCs.Typically,age-related WMCs were observed in the frontal lobes,while hypertension-related WMCs tended to occur in the basal ganglia and infratentorial area.

OBJECTIVE: Adjuvant chemotherapy was introduced in patients with early-stage ovarian cancer (OC). The benefit of standard chemotherapeutic regimens including taxane has not been established. METHODS: Patients with early-stage OC from the National Health Insurance Research database of Taiwan who received platinum plus cyclophosphamide (CP) or platinum plus paclitaxel (PT) for 3–6 cycles were recruited, and the disease-free survival (DFS) and overall survival (OS) were determined. RESULTS: A total of 1,510 early-stage OC patients, including 841 who received CP regimen and 699 who received PT regimen, were included. The 2 groups had a similar estimated probability of 5-year DFS (PT vs. CP, 79.0% vs. 77.6%; p=0.410) and OS (84.6% vs. 84.3%; p=0.691). Patients >50 years of age who received the CP regimen had a lower 5-year DFS than the patients ≤50 years of age who received the CP (p<0.001) or PT regimens (p=0.001). Additionally, patients >50 years of age who received the CP regimen had a worse 5-year OS compared with the other 3 groups (p=0.019) (p=0.179 for patients >50 years of age in the PT group; p=0.002 for patients ≤50 years of age in the CP group; and p=0.061 for patients ≤50 years of age in the PT group). Patients with the CP or PT regimen for 3–5 cycles had a similar 5-year DFS and OS compared to 6 cycles (p>0.050). CONCLUSION: Chemotherapeutic regimens with taxane could be recommended for early-stage OC patients >50 years of age.

ObjectiveHydrogen sulfide (HS), a gaseous signal molecule, plays a crucial role in many pathophysiologic processes in the cardiovascular system. Autophagy has been shown to participate in the occurrence of many cardiac diseases. Increasing evidences indicated that HS regulates myocardial structure and function in association with the altered autophagy and plays a "switcher" role in the autophagy of myocardial diseases. The aim of this review was to summarize these insights and provide the experimental evidence that HS targets cardiomyocyte autophagy to regulate cardiovascular function.

Data SourcesThis review was based on data in articles published in the PubMed databases up to October 30, 2017, with the following keywords: "hydrogen sulfide," "autophagy," and "cardiovascular diseases."

Study SelectionOriginal articles and critical reviews on HS and autophagy were selected for this review.

ResultsWhen autophagy plays an adaptive role in the pathogenesis of diseases, HS restores autophagy; otherwise, when autophagy plays a detrimental role, HS downregulates autophagy to exert a cardioprotective function. For example, HS has beneficial effects by regulating autophagy in myocardial ischemia/reperfusion and plays a protective role by inhibiting autophagy during the operation of cardioplegia and cardiopulmonary bypass. HS postpones cardiac aging associated with the upregulation of autophagy but improves the left ventricular function of smoking rats by lowering autophagy.

ConclusionsHS exerts cardiovascular protection by regulating autophagy. Cardiovascular autophagy would likely become a potential target of HS therapy for cardiovascular diseases.

BACKGROUND: Bioabsorbable biomaterials are of crucial importance in tissue engineering applications, and various factors affect their degradation. OBJECTIVE: To compare the degradation characteristics of concentrated growth factor (CGF) clot and CGF membrane in simulated body fluid (SBF) and simulated saliva fluid (SSF). METHODS: Fifteen volunteers were selected, and human blood samples were collected for the preparation of CGF clot or CGF membrane. All specimens from each subject were averagely divided into four groups: group A, CGF clot in SBF; group B, CGF clot in SSF; group C, CGF membrane in SBF; group D, CGF membrane in SSF. The specimens were subjected to the immersion test. The average daily rate of degradation of each group was calculated after the samples were thoroughly degraded, and weight loss ratio per unit time was also determined. RESULTS AND CONCLUSION: (1) The mean degradation time in groups A-D were (14.0±0.7), (9.7±0.9), (9.9±1.2) and (7.2±0.7) days, respectively. (2) By comparing CGF membrane with CGF clot in the same simulated fluid, the average daily degradation rate of CGF clot (groups A, B) was statistically significantly lower than counterparts of CGF membrane (groups C, D) (P < 0.05). By comparison between SBF and SSF, the average daily degradation rate in the SBF (groups A, B) was significantly lower than counterparts in the SSF (groups C, D) (P <0.05). Overall, the degradation rate of CGF membrane is higher than that of CGF clot under the same degradation environment; for CGF membrane or CGF clot, the degradation rate in SSF is higher than that in SBF.

Syncope is a common emergency of children and adolescents,which has serious influence on the quality of life.Neurally-mediated syncope,including postural tachycardia syndrome,vasovagal syncope,orthostatic hypotension and orthostatic hypertension,is the main cause of syncope in children and adolescents.The main manifestations of neurally-mediated syncope are diverse,such as dizziness,headache,chest tightness,chest pain,pale complexion,fatigue,pre-syncope and syncope.Although the clinical manifestations are similar,each subtype of syncope has its hemodynamic feature and optimal treatment option.The diagnosis rate of syncope in children has been greatly improved on account of the development of the diagnostic procedures and methods.In recent years,with the promotion of head-up tilt test and drug-provocated head-up tilt test,the hemodynamic classification of neurally-mediated syncope gets continually refined.In recent years,with the effort of clinicians,an appropriate diagnostic protocol for children with syncope has been established.The initial evaluation consists of history taking,physical examination,standing test and standard electrocardiography.After the initial evaluation,some patients could be diagnosed definitely,such as postural tachycardia syndrome,orthostatic hypotension,and situational syncope.Those with a specific entity causing syncope need selective clinical and laboratory investigations.Patients for whom the cause of syncope remained undetermined should undergo head-up tilt test.The precise pathogenesis of neurally-mediated syncope is not entirely clear.In recent years,studies have shown that neurally-mediated syncope may be related to several factors,including hypovolemia,high catecholamine status,abnormal local vascular tension,decreased skeletal muscle pump activity and abnormal neurohumoral factors.Currently based on the possible pathogenesis,the individualized treatment of neurally-mediated syncope has also been studied in-depth.Generally,the management of neurallymediated syncope includes non-pharmacological and pharmacological interventions.Patient education is the fundamental part above all.In addition to exercise training,the first-line treatments mainly include oral rehydration salts,beta adrenoreceptor blockers,and alpha adrenoreceptor agonists.By analyzing the patient's physiological indexes and biomarkers before treatment,the efficacy of medication could be well predicted.The individualized treatment will become the main direction in the future researches.
