Objective To determine the influence and significance of combinative assessment of 64 multi-slice spiral computed tomography (MSCT) with serum amyloid A protein (SAA) or C-reactive protein (CRP) on the selection of operative procedures of rectal cancer under the multi-disciplinary team. Methods Prospectively enrolled patients diagnosed definitely as rectal cancer at West China Hospital of Sichuan University from February to August 2009 were randomly assigned into two groups. In one group named MSCT+SAA group, both 64 MSCT and SAA combinative assessment were made for the preoperative evaluation. In another group named MSCT+CRP group, both MSCT and CRP combinative assessment were made for preoperative evaluation. Furthermore, the preoperative staging and predicted operation procedures were compared with postoperative pathologic staging and practical operation procedures, respectively, and the relationship between the choice of operation procedures and clinicopathologic factors was analyzed. Results All 165 patients were randomly assigned into MSCT+SAA group (n=83) and MSCT+CRP group (n=82). The baseline characteristics of two groups were statistically similar (Pgt;0.05). For MSCT+SAA group, the accuracies of preoperative staging T, N, M and TNM were 74.7%， 68.7%, 100% and 66.3%, respectively. For MSCT+CRP group, the accuracies of preoperative staging T, N, M and TNM were 72.0%, 86.6%, 100% and 81.7%, respectively. There were statistically significant differences in the accuracies of N staging and TNM staging between two groups (P＜0.05). However, there was no statistically significant difference of the accuracy of prediction to operative procedures between two groups (90.4% vs. 95.1%, Pgt;0.05). The pathological T staging (P＜0.001), N staging (P＜0.001), TNM staging (P＜0.001), preoperative serum level of SAA (P=0.010), serum level of CRP (P=0.042), and distance of tumor to the dentate line (P=0.011) were associated with the operative procedures. Conclusion Combinative assessment of MSCT+CRP could improve the accuracy of preoperative staging and operative procedures prediction, which may be superior to MSCT+SAA.
Objective To determine the influence of combinative assessment of transrectal ultrasound (TRUS) and serum amyloid A protein (SAA) on the assessment of preoperative staging selection of operative procedures in the middle and lower rectal cancer. Methods Prospectively enrolled 130 patients, who diagnosed definitely as middle and lower rectal cancer at West China Hospital of Sichuan University from June 2008 to February 2009 were randomly assigned into two groups with 65 participants, respectively. In one group named TRUS combined SAA group, both TRUS and SAA combinative assessment were made for the preoperative evaluation. In another group named TRUS group, only the preoperative TRUS was made. The preoperative staging and predicted operative procedures were compared with postoperative pathologic staging and practical operation program, respectively.Results Of 118 patients with rectal cancer were actually included into TRUS combined SAA group (n=59) and TRUS group (n=59). The baselines of characteristics of two groups were basically identical. For TRUS combined SAA group， the accuracies of preoperative T and N staging were 79.7% (47/59) and 77.8% (42/54) respectively; For TRUS group the corresponding rates were 86.4% (51/59) and 57.7% (30/52), respectively. There was no statistically significant difference of the accuracy of preoperative T staging （P=0.609） while preoperative N staging had statistical difference (P=0.027) between two groups. There was a statistically significant difference of the accuracy of prediction to operative procedures in two groups 〔96.6% (57/59) vs. 83.1% (49/59), P=0.015〕. The preoperative T staging was related to the selection of operative procedures (P=0.037) when analyzing the relationship between the operative procedures and the multiple clinicopathological factors in middle and lower rectal cancer. ConclusionCombinative assessment of TRUS and SAA could improve the accuracy of preoperative staging in middle and lower rectal cancer, thus provide higher predictive coincidence rate to operative procedures for surgeon.
Objective To verify the association between admission serum phosphate level and short-term (<30 days) mortality of severe pneumonia patients admitted to intensive care unit (ICU) / respiratory intensive care unit (RICU). Methods Severe pneumonia patients admitted to the ICU/RICU of Quanzhou First Hospital Affiliated to Fujian Medical University from November 2019 to September 2021 were included in the study. Serum phosphate was demonstrated as an independent risk factor for short-term mortality of severe pneumonia patients admitted to ICU/RICU by logical analysis and receiver operator characteristic (ROC) curve. The patients were further categorized by serum phosphate concentration to explore the relationship between serum phosphate level and short-term mortality. Results Comparison of baseline indicators at admission between the survival group (n=54) and the non survival group (n=46) revealed that there was significant difference in serum phosphate level [0.9 (0.8, 1.2) mmol/L vs. 1.2 (0.9, 1.5) mmol/L, P<0.05]. Logical analysis showed serum phosphate was an independent risk factor for short-term mortality. ROC curve showed that the prediction ability of serum phosphate was close to pneumonia severity index (PSI). After combining serum phosphate with PSI score, CURB65 score, and sequential organ failure score, the predictive ability of these scores for short-term mortality was improved. Compared with the normophosphatemia group, hyperphosphatemia was found be with significantly higher short-term mortality (85.7% vs. 47.3%, P<0.05), which is absent in hypophosphatemia (25.8%). Conclusions Serum phosphate at admission has a good predictive value on short-term mortality in severe pneumonia patients admitted to the ICU/RICU. Hyperphosphatemia at admission is associated with a higher risk of short-term death.
It was reported in this article that a preparation of acid/heat-stable peptides (AHSP) from pig serum with a molecular-weight less than 18 ku a without antigenity and toxicity could exert enhancement effect on wound healing. Two pieces of polyvinyl alcohol (PVA) sponge implanted in rat dorsal subcutaneous pouchs of 20 mice were selected as the wound model. The subcutaneous pouch having one piece of sponge was taken as the experimental group and the other as the control. Injection of 50 microliters of such peptide preparation into the test sponge was performed once a day from the time of injury on for 5 consecutive times, while 50 microliters of BSA (5 mg/ml) into the control sponge in the same way. The levels of total DNA, protein and hydroproline in AHSP-treated sponge were observed significantly higher than those in the control sponge on the 7th and 10th days after wounding (P lt; 0.05). No significant difference was seen on the 14th postinjury day (P gt; 0.05). The effect of AHSP on proliferation of wound fibroblast cultured in vitro was also detected. In conclusion, such peptides derived from pig serum had the activity to accelerate wound healing without resultant excessive healing and its direct stimulation of the proliferation of wound fibroblast was probably one of the way which AHSP exerted its action.
【Abstract】Objective To search for valuable serum tumor markers in diagnosis and prognosis of pancreatic carcinoma. Methods Seven kinds of serum tumor markers including AFP,CEA,CA50, CA15-3,CA19-9,CA72-4 and CA125 were detected in 62 patients with pancreatic carcinoma by Auto DELFIA and IRMA, 16 patients with other gastrointestinal tumors and 16 patients with benign diseases served as control. And 19 patients after pancreatectomy were followed up. Results Among these 7 kinds of tumor markers, CA19-9,CA50 and CA125 were valuable in diagnosis of pancreatic carcinoma. CA19-9 was the most valuable one, whose sensitivity and specificity were 90.6% and 86.7% respectively. After resection of the tumor, the 3 markers tended to decrease significantly. Conclusion Serum CA19-9,CA50 and CA125 were valuable in diagnosis and following up of pancreatic carcinoma.
Objective To discuss the influence of combination of 64 multi-slice spiral computer tomography (MSCT) and serum amyloid A protein (SAA) for preoperative assessment on colon cancer surgery strategy. Methods Ｔhe examination data of 110 patients diagnosed definitely as colon cancer in the West China Hospital of Sichuan University from Nov. 2007 to Nov. 2008 were studied prospectively, and randomly assigned into the MSCT+SAA group and MSCT group, respectively. Both MSCT and SAA combinative assessment were made for preoperative evaluation in MSCT+SAA group, while only MSCT was made preoperatively in MSCT group. Furthermore, the preoperative staging and prediction of operative procedures were compared with postoperative pathologic staging and practical of operative procedures, respectively. Results According to the inclusion criteria, 99 colon cancer patients were actually included into MSCT+SAA group (n=49) and MSCT group (n=50). The baseline characteristics of two groups were statistically identical. For MSCT+SAA group, The accuracies of preoperative staging T, N, M and TNM were 81.6%, 79.6%, 100% and 77.6%, respectively. For MSCT group, the corresponding rates were 82.0%, 60.0%, 98.0% and 62.0%, respectively. The difference of accuracies on staging N between two groups was observed statistically (χ2=4.498, P=0.034). There was also a statistically significant difference of the accuracy of prediction of operative procedures in MSCT+SAA group and MSCT group (95.9% vs. 82.0%, χ2=4.854, P=0.028). The preoperative staging N (P=0.008), M (P=0.010), TNM (P=0.009) and level of SAA (P=0.004) were related to the selection of operative procedures when analyzed the relationship between the operative procedures and multiple clinicopathologic factors in colon cancer. Conclusion The strategy of the combinative assessment of MSCT and SAA could advance the accuracy of preoperative staging, thus serve surgeon the more accurate prediction to surgery strategy in colon cancer.
ObjectiveTo explore the influence factors of gallstone. MethodsClinical data of 511 patients who were admitted to our hospital from Apr. 2015 to Apr. 2016 were retrospectively analyzed. ResultsOf 511 patients, there were 274 patients with gallstone (gallstone group) and 237 patients without gallstone (control group). Univariate analysis results showed that, no significant difference of age, gender, and diabetes was found between gallstone group and control group (P > 0.050), but the levels of serum total cholesterol (TC), triglyceride (TG), low density lipoprotein (LDL-C), and fasting blood glucose (FBG) were significantly higher in patients of gallstone group (P < 0.050), but the level of serum high density lipoprotein (HDL-C) was significantly lower in patients of gallstone group (P=0.001). Logistic regression results showed that four factors including diabetes〔OR=4.491; 95% CI is (2.021, 9.976); P < 0.001〕, the serum TC〔OR=2.548; 95% CI is (1.944, 3.338); P < 0.001〕, HDL-C〔OR=0.115; 95% CI is (0.056, 0.237); P < 0.001〕, and FBG〔OR=1.277; 95% CI is (1.086, 1.502); P=0.003〕 entered the final regression model after controlling confounding factors. The results showed that patients who combined with diabetes, high levels of serum TC and FBG, and low level of serum HDL-C, had higher ratio of galls-tone. ConclusionDiabetes, high-level of serum TC and FBG, low-level of serum HDL-C were risk factors of gallstone.
ObjectiveTo investigate the relationship between admission serum potassium level and long-term prognosis in patients with unstable angina. MethodsWe studied the data of 1 412 patients with unstable angina who received coronary angiography examinations and completed the follow-up between July 2008 and September 2012. Serum potassium level within the first 24 hours after admission was collected. According to the serum potassium level, the patients were divided into three groups:those with a serum potassium level lower than 3.5 mmol/L, those with a level between 3.5 and 5.0 mmol/L and those with a level higher than 5.0 mmol/L. Then, we analyzed the relationship between admission serum potassium level and long-term prognosis in patients with unstable angina. ResultsThere was a U-shaped relationship between admission serum potassium level and long-term mortality that persisted after multivariable adjustment in patients with unstable angina. The all-cause mortality risk was the lowest in the group of patients with a potassium level of 3.5 to 5.0 mmol/L, whereas mortality was higher in patients with potassium level lower than 3.5 mmol/L and higher than 5.0 mmol/L [HR=1.89, 95%CI (1.13, 3.17), P=0.016; HR=1.64, 95%CI (0.40, 6.77), P=0.493]. Compared with patients with a serum potassium level between 3.5 and 5.0 mmol/L, the cardiovascular mortality risk was significantly higher in those patients with a potassium level lower than 3.5 mmol/L [HR=1.99, 95%CI (1.01, 3.94), P=0.048]. ConclusionThere is a U-shaped relationship between admission serum potassium level and long-term all-cause mortality rate, and the all-cause mortality rate and cardiovascular mortality risk was the lowest in patients with a potassium level between 3.5 and 5.0 mmol/L.
ObjectivesTo systematically review the association between serum high sensitivity C-reactive protein (HS-CRP) and nonalcoholic fatty liver disease (NAFLD).MethodsPubMed, EMbase, The Cochrane Library, CNKI, SinoMed and WanFang Data databases were electronically searched to collect case-control studies on the association between HS-CRP and NAFLD from inception to October, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 software.ResultsA total of 22 case-control studies involving 5 825 subjects were included. The results of meta-analysis showed that HS-CRP levels in NAFLD group were higher than non-NAFLD group (SMD=1.25, 95%CI 0.81 to 1.68, P<0.000 01). The results of subgroup analysis showed that, HS-CRP levels in NAFLD group were higher in Asian region (SMD=1.32, 95%CI 0.82 to 1.83, P<0.000 01), however not in American region (SMD=0.48, 95%CI ?0.02 to 0.98, P=0.06). HS-CRP levels in NAFLD group were higher in BMI≥30 kg/m2 group (SMD=0.37, 95%CI 0.19 to 0.54, P<0.000 1), however not in BMI<30 kg/m2 group (SMD=1.19, 95%CI ?0.28 to 2.66, P=0.11). Additionally, HS-CRP levels in NAFLD group were higher with or without diabetes (SMD=0.86, 95%CI 0.49 to 1.24, P<0.000 01; SMD=1.47, 95%CI 0.84 to 2.10, P<0.000 01).ConclusionsCurrent evidence shows that NAFLD patients have higher levels of HS-CRP than non-NAFLD patients, and are affected by high levels of BMI and geographical regions. Therefore, HS-CRP may play important roles in the non-invasive field of NAFLD detection. Due to limited quality and quantity of the included studies, more high quality studies are required to verify above conclusions.
ObjectiveTo explore the correlation of serum levels of 5-hydroxytryptamine (5-HT) and 5-HT2A receptor gene T102C polymorphism with suicidal behavior by poison in non-depressive patients, in order to diagnose and intervene the suicidal behavior of patients as early as possible. MethodsSixty-two non-depressive patients with the behavior of suicide by poison treated between January 2013 and June 2014 were selected as patient group, and other 66 healthy persons were selected as control group. Peripheral blood in the two groups of patients were collected to test the serum levels of 5-HT with enzyme linked immunosorbent assay, and the 5-HT2A receptor gene T102C polymorphism was detected by polymerase chain reaction-restriction fragment length polymorphism. The data were analyzed by SPSS 19.0 statistically. ResultsThe serum level of 5-HT in the patient group was significantly lower than that in the control group (P<0.001), and the frequency of T102C genotype in the patient group was higher than the control group (χ2=5.533, P=0.013). The distribution of genotype was different, and homozygous mutations of CC in the patient group were higher than the control group (χ2=5.648, P=0.017). ConclusionThe serum levels of 5-HT and 5-HT2A receptor gene T102C polymorphism, and the frequency of T102C genotype may be related to suicidal behavior by poison in non-depressive patients.
