RESUMO
Background/Aims@#Functional dyspepsia (FD) overlapping with other gastrointestinal disorders are quite common. The characteristics of FD overlap in Chinese population with latest Rome IV criteria were unclear. This large-scale outpatient-based study assessed the characteristics of FD overlap in South China. @*Methods@#Consecutive FD patients visited the Gastroenterology Clinic at 2 tertiary medical centers in Hangzhou, China who fulfilled the Rome IV criteria were enrolled. Complete questionnaires related to the gastrointestinal symptoms (Rome IV criteria), Reflux Disease Questionnaire, anxiety and depression, quality of sleep and life, and demographic information were collected. @*Results@#Among the total of 3281 FD patients, 50.69% overlapped with gastroesophageal reflux disease, 21.46% overlapped with irritable bowel syndrome, 6.03% overlapped with functional constipation. FD overlap had higher proportion of single/divorced/widowed rate, high education level, being employed, drinking, night shift, unhealthy dietary habit than FD only (P < 0.05). They had higher frequency of consultation and economic burden, as well as lower scores in quality of life (P < 0.001). Multivariate logistic regression showed that increasing age, female, low body mass index, history of gastroenteritis, anxiety, depression, and poor sleep quality were independent risk factors for FD overlap. @*Conclusions@#FD overlap was quite common in China with high economic burden and poor quality of life, FD patients with history of gastroenteritis, anxiety, depression, and poor sleep quality were more likely to have overlap disorders. Awareness of the physical and psychosocial stressors in overlapping condition would help optimize the management of FD overlap in clinical practice.
RESUMO
ObjectiveThere are a few reports about the expression of SNHG3 in breast cancer and its effects. This study aimed to detect the expression of SNHG3 in breast cancer and paracancerous tissues, along with its relevance to clinicopathological parameters.MethodsSeventy-four patients with breast cancer were confirmed pathologically in our hospital from Jan. 2014 to Dec. 2017. The expression of SNHG3 was examined in breast cancer and paracancerous tissues by qRT-PCR. Correlations between the expression of SNHG3 and clinicopathological parameters were analyzed.Results SNHG3 expression was significantly downregulated in breast cancer tissues compared to paracancerous tissues, and the difference was of statistical significance (P<0.000). Low expression of SNHG3 was in negative correlation to Ki-67 (rs=-0.296, P=0.013).ConclusionThe expression of SNHG3 downregulated in breast cancer tissues, and its expression level is related to Ki-67, which may serve as a potential diagnostic molecular marker.

<p><b>OBJECTIVE</b>To observe the hemodynamic changes in patients undergoing pericardiectomy at different operational stages.</p><p><b>METHODS</b>Totally 16 consecutive patients receiving radical pericardiectomy were enrolled in this observational study. Hemodynamic variables were monitored continuously by pulse-indicated continuous cardiac output(PiCCO)system. Totally,three sets of intraoperative hemodynamic parameters were obtained at three different stages of pericardiectomy.</p><p><b>RESULTS</b>During the pericardiectomy,the cardiac index[CI,(1.9±0.6),(2.7±0.6),(3.0±0.5)L·min(-1)·m(-2);P<0.05]and stroke volume index[SI,(22.5±8.7),(29.9±8.5),(30.1±8.5)dyn·s·cm(-5)·m(2);P<0.05]showed significant improvement,whereas central venous pressure[CVP,(17.1±5.0),(13.3±3.9),(12.3±3.0)mmHg;P<0.05]decreased significantly. Global end-diastolic volume index[GEDVi,(533±156),(580±153),(559±144)ml·m(-2);P<0.05]increased and stroke volume variation[SVV,(15.6±6.1)%,(10.8±4.2)%,(9.4±5.4)%;P<0.05]decreased intra-operatively. The majority of the above-mentioned hemodynamic improvements occurred after the resection of pericardium over the left ventricular outflow tract(LVOT).</p><p><b>CONCLUSIONS</b>PiCCO system can serve as a reliable,less invasive hemodynamic monitoring method during pericardiectomy. Resection of the pericardium over the LVOT is the most important step of the pericardiectomy.</p>

<p><b>OBJECTIVE</b>To evaluate the influence of different tranexamic acid administration methods during and after cardiac surgery with cardiopulmonary bypass(CPB) on coagulation function and postoperative bleeding.</p><p><b>METHODS</b>Patients undergoing elective cardiac surgery with use of CPB (n=60) were randomized in a double-blind fashion to one of two treatment groups:group A(n=30) , administered with tranexamic acid 10 mg/kg (intravenous injection slowly before skin incision) , followed by infusion of normal saline until postoperative 12 hours;and group B(n=30) , administered with tranexamic acid 10 mg/kg(intravenous injection slowly before skin incision) , followed by infusion of tranexamic acid 1 mg/(kg·h) until postoperative 12 hours. Hemoglobin, platelet count, and coagulation function were assessed before anesthesia induction, after surgery, 8am next day and 24 hours after surgery. Bleeding, allogeneic blood transfusion, and fluid infusion during the postoperative 24 hours were recorded.</p><p><b>RESULT</b>No differences were found between groups in terms of coagulant function, postoperative bleeding, allogeneic blood transfusion, and fluid infusion(P>0.05) .</p><p><b>CONCLUSION</b>Compared with intraoperative administration alone, prolonged treatment with tranexamic acid after cardiac surgery shows no advantage because it can not further improve coagulant function, reduce bleeding, or reduce allogeneic blood transfusion.</p>

<p><b>OBJECTIVE</b>To examine the analgesic effect of calpain inhibitor ALLN on the zymosan-induced paw inflammatory pain and its effect on the expression of cyclooxygenase-2 (COX-2) in the spinal dorsal horn.</p><p><b>METHODS</b>Forty-eight Sprague-Dawley rats were equally divided into three groups: control group, sham-operated group, and zymosan group. According to Meller's method, zymosan (1.25 mg) was injected intraplantarly to induce paw inflammation in zymosan group; an equal volume of PBS was administered in the sham-operated group. Mechanical withdrawal threshold (MWT) and maximum thickness of paw were tested or measured before and 0.5, 1, 2, 4, 8, and 24 hours after injection. All rats were killed at different occasions following surgery to examine calpain activity in the spinal dorsal horn with Western blot analysis. Another sixty-four Sprague-Dawley rats were divided into three groups: sham-operated group, zymosan-induced paw inflammation with intraperitoneal dimethyl sulphoxide (DMSO) treatment group, and zymosan-induced paw inflammation with intraperitoneal calpain inhibitor ALLN treatment group. MWT and maximum thickness of paw were tested or measured before and 0.5, 1, 2, 4, 8, and 24 hours after injection. All rats were killed at different occasions following surgery to examine the COX-2 expression in the spinal dorsal horn with Western blot analysis.</p><p><b>RESULTS</b>MWT significantly decreased in the rats with zymosan-induced paw inflammation, while the maximum thickness of paw significantly increased, compared with control and sham-operated rats (P < 0.05). Calpain in the ipsilateral spinal dorsal horn was dramatically activated after zymosan injection (P < 0.01). Intraperitoneal ALLN injection significantly increased zymosan-induced MWT and decreased paw edema at the same time points after zymosan injection compared with DMSO treatment group (P < 0.05). Meanwhile, calpain inhibitor ALLN treatment significantly decreased the COX-2 expression in the spinal dorsal horn compared with DMSO treatment (P < 0.01).</p><p><b>CONCLUSION</b>Administration of calpain inhibitor ALLN is effective to attenuate zymosan-induced paw inflammatory pain. Calpain activation may be one aspect of the signaling cascade that increases the COX-2 expression in the spinal cord and contributes to mechanical hyperalgesia after peripheral inflammatory injury.</p>

<p><b>OBJECTIVE</b>To investigate the intracellular calcium ion release and the system of calcium channel by 1,25 (OH)2D3 stimulus, and the effect of mechanical pressure on it in rabbit mandibular condylar chondrocytes (MCC) in vitro.</p><p><b>METHODS</b>In vitro cultured MCC from two-week-old New Zealand rabbits were incubated under 20 g/L heparin, 1 g/L procaine, continuous pressure of 90 kPa for 60 min and 360 min in a hydraulic pressure controlled cellular strain unit. With the Fluo-3/AM probe loaded, 1,25(OH)2D3 was added to the medium and then the intracellular calcium level was detected by a laser confocal scanning microscope.</p><p><b>RESULTS</b>Intracellular calcium concentration increased in MCC treated with 1,25(OH)2D3, 1,25(OH)2D3 and procaine, while it didn't change in heparin treated group. Calcium in group under continuous pressure of 90 kPa for 60 min was also increased, even higher than the group stimulated only with 1,25(OH)2D3. Intracellular calcium in group treated with continuous pressure of 90 kPa for 360 min showed no significant difference compared to the control and even decreased at the end of the recording period.</p><p><b>CONCLUSION</b>1,25(OH)2D3 could stimulate the intracellular calcium release channel of inositol triphosphate (IP3) receptor open in MCC in vitro and increases the level of intracellular calcium concentration. Pretreatment of definite mechanical pressure could modulate the sensitivity of IP3 channel to 1,25(OH)2D3 stimulus.</p>

<p><b>OBJECTIVE</b>To observe the effectiveness of using cell saver (CS) during surgery on blood sparing and its impact on patient's hematology and coagulation function.</p><p><b>METHODS</b>One-hundred and thirty-eight patients undergoing elective surgery were recruited for intraoperative blood salvage using CS. Blood routine, blood chemistry and coagulation function were measured before surgery, after infusion of salvaged blood and postoperative day 1, respectively.</p><p><b>RESULTS</b>In total, 112,056 ml of packed red blood cells were collected, with a mean value of 812 ml per patient. The percentage of autologous blood transfusion volume to the total blood transfusion volume was from 48% to 89%. Allogenic blood transfusion rate was from 5% to 100%. Compared with the values before surgery, the hemoglobin concentration, platelet count, plasma total protein and fibrinogen concentration decreased significantly after the transfusion of salvaged blood and the first postoperative day (P < 0.05 or P < 0.01), while the prothrombin time was significantly prolonged (P < 0.05).</p><p><b>CONCLUSIONS</b>The use of CS during surgery can, to a certain extent, reduce the requirement of allogenic blood. However, reinfusion of large amount of salvaged blood may affect coagulation function.</p>
