Objective To investigate the expressions of insulin-like growth factor receptor-1 (IGF-1R) and insulin-like growth factor binding protein-3 (1GFBP-3) and their correlations with clinicopathological parameters in the primary colon cancer,as well as their roles in lymph node metastasis of colon cancer.Methods The expressions of IGF-1R and IGFBP-3 in 78 cases of colon cancer tissues and 78 cases of normal colon mucosa tissues were detected by SP immunohistochemical technology and the correlations between the expressions and the clinical pathological parameters of colon cancer were analyzed.Results The positive rate of IGF-1R in colon cancer (66.7％,52/78) was significantly higher than that in control group (24.4％,19/78),x2 =28.150,P =0.000.The positive rate of IGFBP-3 in colon cancer (73.1％,57/78) was significantly lower than that in control group (89.7％,70/78),x2 =7.158,P =0.007.IGF-1R expression in colon cancer was significantly correlated with the invasion (x2 =5.804,P =0.016),TNM stage (x2 =5.246,P =0.022) and lymph node metastasis (x2 =12.955,P =0.000).IGFBP-3 expression in colon cancer was signi-ficantly correlated with the TNM stage (x2 =7.096,P=0.008),lymph node metastasis (x2 =5.893,P =0.015) and distant metastasis (P =0.003).Both with other factors had no significant correlation (P ＞ 0.05).1GF-1R expression and IGFBP-3 expression showed a negative correlation (r =-0.245,P =0.03).Conclusion The over expression of IGF-1R and low expression of IGFBP-3 are associated with TNM stage and lymph node metastasis in colon cancer.IGF-1R and IGFBP-3 may become new targets of the treatment of colon cancer.

Objective To discuss the clinical results of lateral locking plate combined with bone grafting in the treatment of distal femoral fractures in the elderly.Methods Between January 2006 and December 2013,112 senile patients with distal femoral fracture were treated at our department by lateral locking plate combined with bone grafting.They were 16 men and 96 women,aged from 67 to 85 years (average,76.1 years).By AO classification,48 cases were type 33-A1,11 type 33-A2,3 type 33-A3,7 type 33-B1,4 type 33-B2,32 type 33-C1,and 7 type 33-C2.All of them had a previous history of osteopenia.By the Singh index classification,22 cases were rated as grade Ⅰ,74 as grade Ⅱ,13 as grade Ⅲ,and 3 as grade Ⅳ.Postoperatively,the patients conformed to regular follow-up,accepted functional rehabilitation and continued medication for osteopenia.Radiographic examinations were conducted to observe fracture healing.At the last follow-up,the function of involved knee was assessed according to the criteria by Karlstrom and Olerud.Results All the 112 patients completed their follow-ups,ranging from 10 to 48 months (average,16 months).All fractures united primarily after an average of 4.2 months (range,from 3.5 to 5.0 months).According to the criteria by Karlstrom and Olerud,93 cases were rated as excellent,10 as good and 9 as fair,giving a good-to-excellent rate of 92.0％.No such complications as nonunion,malunion,plate breakage,or screw loosening were observed during the follow-ups.Conclusion Lateral locking plate combined with bone grafting is effective for the treatment of distal femoral fractures in the elderly,if followed by postoperative anti-osteopenia therapy and early functional exercises.

Objective To investigate the impacts of soluble dietary fiber (SDF) on gastric emptying,postprandial blood glucose and insulin in patients with type 2 diabetes mellitus (T2DM).Methods Totally 30 T2DM patients and 10 healthy subjects (control group) were randomized to receive SDF-free liquid (500 ml,2092 kJ) and isocalorie SDF liquid (at β-glucan 7.5 g,500 ml,2092 kJ) on two separate days based on a Cross-over order.Gastric emptying was monitored by ultrasomography at intervals of 30 min for 2 hours.Fasting and postprandial blood samples were collected at intervals of 30-60 min for 180 min to determine blood glucose and insulin.Results The proximal gastric emptying was delayed in SDF both in T2DM group (P =0.001)and control group (P =0.037).SDF significantly decreased the area under the curve of postprandial glucose (P =0.001) and insulin (P =0.001) in T2DM group.Postprandial glucose (r=-0.547,P =0.047) and insulin (r =-0.444,P =0.030) had negative correlation with distal emptying of SDF in T2DM patients.The distal gastric emptying was delayed significantly in T2DM patients with HbAlc≥6.5％ (n =13,P =0.021)by SDF.Conclusions SDF can improve the postprandial glucose level,which may be related with the delayed gastric emptying.T2DM patients with higher average blood glucose has remarkably delayed gastric emptying after the administration of SDF.

Methods Immunohistochemistry and Western blotting for the expression of FGF-2 and FGFR-4 were performed in 89 cases of PTC and 30 cases of normal thyroid tissues ( NTT) adjacent to the tumors .Results Immunohistochemistry results showed that , FGF-2 and FGFR-4 expressions were high in thyroid carcinoma (P<0.01,P<0.01) in contrast to that in the normal thyroid tissues, and the difference was statistically significant;There was a positive linear correlation between expressions of FGF-2 and FGFR-4 and lymph node metastasis (χ2 =14.798,P<0.01;χ2 =7.27,P<0.01)and differentiation degree (χ2=13.824,P<0.01;χ2 =16.921, P<0.01) in papillary thyroid carcinoma ,while there was no difference in gender ,age and tumor size(P>0.05).Analyzed by Western blotting technique ,FGF-2 and FGFR-4 expressions in thyroid carcinoma were significantly higher than that in normal tissue ,with decrease of cancer degree of tissue differentiation and significantly up regulated expression (P<0.05).Expressions of FGF-2 and FGFR-4 were in a positive linear correlation in the disease (rs=0.434,P<0.01).Conclusion The expressions of FGF-2 and FGFR-4 are correlated with papillary thyroid cancer and they participated in the process of invasion and metastasis , both of which have a positive synergistic effect .The degree of malignancy and biological behavior are meaningful and comprehensive indicators ,which provide a theoretical basis for the subsequent experimental studies of cellular and molecular biology .

Objective To explore the value of amplitude integrated electroencephalography ( aEEG) in diagnosis and prognosis in neonates with acute hypoglycemic brain injury. Methods A total of 47 cases of neonatal hypoglycemic brain injury were prospectively enrolled in the study from January 2011 to July 2015. The aEEG traces were classified according to background activity ( normal,moderate,or severely abnormal) , presence of seizures and sleep-wake cycling ( SWC) . The neuromotor development of survivors with neonatal hypoglycemic brain injury was assessed by using the 0-6 years old children′s neurological and psychological development scale of China Capital Institute of Pediatrics. Clinical data were collected and compared with the result of aEEG. Results The characteristic of aEEG tracings in 47 infants showed continuous normal voltage (CNV)(n=9),discontinuous voltage(DC)(n=29),continuous low voltage(CLV)(n=3),burst-suppres-sion(BS)(n=6);mature sleep-wake cycling(SWC)(n=9),immature SWC(n=17),no SWC (n=21);39 infants(83. 0%) had electrical seizures:single seizure(n=11),repetitive seizures(n=20),and status ep-ilepticus (SE)(n=8). aEEG of 23 infants who had poor outcome showed CLV(n=3),BS/SE(n=4),BS/repetitive seizures( n =2 ) , DC/SE ( n =4 ) , DC/repetitive seizures ( n =10 ) . By chi-square analysis and Spearman rank correlation analysis,the results of aEEG classification,background pattern and SWC were cor-related with outcome of these infants with hypoglycemic brain injury. Conclusion Amplitude integrated electroencephalography can provide important information of the status of cerebral function in neonates with acute hypoglycemic brain injury and help to predict their outcome.

Objective:To investigate the correlation between bronchial wall thickness that was determined by high-resolution computed tomography(HRCT)on lung,and pulmonary function and curative efficacy of patients with chronic obstructive pulmonary disease(COPD).Methods:From January 2020 to December 2022,a total of 154 COPD patients were retrospectively selected as the observation group.According to the indicator of the percentage of forced expiratory volume in the first second(FEV1%),the patients were divided into high-risk group(grade Ⅰ,n=51),mild group(grade Ⅱ,n=45),moderate group(grade Ⅲ,n=35)and severe group(grade Ⅳ,n=23)as the 2023 global initiative for chronic obstructive lung disease(GOLD)scale.At the same time,67 healthy subjects were selected as healthy control group.All of them underwent HRCT scan on their chest,and the thickness of the bronchial wall at the opening of the bronchus of bilateral lung apex was measured.The percentage of forced expiratory volume at the first second(FEV1%),forced expiratory volume at the first second(FEV1)and FEV1/forced vital capacity(FEV1/FVC%)(percentage of forced vital capacity)were measured by the pulmonary function apparatus.Pearson correlation analysis software was used to analyze the correlation between bronchial wall thickening and lung function and curative efficacy.Results:The left bronchial wall thickness(1.49±0.21)mm and the right bronchial wall thickness(1.52±0.24)mm in the observation group were higher than those in the healthy control group(t=18.041,15.504,P<0.05),respectively.In the observation group,the higher GOLD grading of the subgroup has higher thickness at the left and right sides of bronchial walls,and there were also significant differences at the thicknesses of bilateral bronchial walls among different grading groups(F=13.888,25.841,P<0.05),respectively.The FEV1(1.82±0.32),FEV1/FVC%(63.09±5.26)and FEV1%(63.36±6.03)in COPD patients of the each subgroup of observation group were lower than those of healthy control group,and the differences were statistically significant(t=6.693,15.392,7.944,P<0.05),respectively.In the observation group,patients with higher GOLD grade has lower decreasing level of the FEV1,FEV1/FVC%and FEV1%,and there were statistically significant differences in pulmonary function levels among the subgroups of the observation group(F=166.541,141.751,57.120,P<0.05),respectively.The results of Pearson correlation analysis showed that the left and right sides of bronchial wall thickening of HRCT scan on COPD patients were positively correlated with FEV1,FEV1/FVC%and FEV1%levels of pulmonary function in COPD patients(r=0.451,0.503,0.498,0.531,0.488.0.515,P<0.05),respectively.Conclusion:The thickness of bronchial wall of HRCT scan images on lung appears high expression in COPD patients,and its expression level can reflect the severity of patients'disease,and has a strong correlation with pulmonary function.

Objective:To investigate the efficacy and safety of atorvastatin combined with indobufen in the treatment of elderly patients with diabetic kidney disease (DKD) complicated with large atheromatous ischemic stroke (LAA-IS) during convalescence.Methods:The clinical data of 102 elderly patients with DKD complicated with LAA-IS during convalescence from September 2018 to April 2022 in Baoding Second Central Hospital were retrospectively analyzed. Among them, 51 patients were treated with atorvastatin combined with indobufen (observation group), 51 patients were treated with atorvastatin combined with aspirin (control group), and both groups were treated continuously for 6 months. The prethrombotic state indexes, neurological function and quality of daily life, carotid artery ultrasound indexes, renal fibrosis indexes before treatment and after treatment were compared between two group. The prethrombotic state indexes included arachidonic acid (AA) and adenosine diphosphate (ADP) induction platelet aggregation rate, fibrinogen (FIB), protein C; the National Institutes of Health Stroke Scale (NIHSS) was used to evaluate the neurological function, and the modified Barthel index (MBI) was used to evaluate the quality of daily life; carotid artery ultrasound indexes included carotid artery intima-media thickness (IMT) and maximum plaque area; the renal fibrosis indexes included transforming growth factor-β 1 (TGF-β 1), matrix metalloproteinase-9 (MMP-9), hyaluronic acid and platelet derived growth factor-BB (PDGF-BB). The adverse reactions were recorded. Results:There were no statistical differences in the all indexes before treatment between two groups ( P>0.05). In two groups, compared before treatment, the AA induction platelet aggregation rate, ADP induction platelet aggregation rate, FIB, NIHSS score, IMT and maximum plaque area after treatment were significantly lower, the protein C and MBI score were significantly higher, and there were statistical differences ( P<0.01); but there were no statistical differences after treatment between two groups ( P>0.05). The TGF-β 1, MMP-9, hyaluronic acid and PDGF-BB after treatment in two groups were significantly lower than before treatment, and the indexes in observation group were significantly lower than those in control group: (39.46 ± 6.89) μg/L vs. (45.04 ± 8.20) μg/L, (278.46 ± 49.39) μg/L vs. (327.30 ± 57.28) μg/L, (102.37 ± 20.62) μg/L vs. (116.84 ± 24.97) μg/L vs. (25.26 ± 4.45) μg/L vs. (28.13 ± 5.08) μg/L, with statistically significant differences( P<0.01). The incidence of adverse reactions in observation group was significantly lower than that in control group: 7.84% (4/51) vs. 23.53% (12/51), and there was statistical difference ( P<0.05). Conclusions:Compared with atorvastatin combined with aspirin, atorvastatin combined with indobufen in elderly patients with DKD complicated with LAA-IS during convalescence has the same effect in improving the related indicators of prethrombotic state, reducing neurological function deficit, improving the ability of daily living, and reversing carotid atherosclerosis. However, atorvastatin combined with indobufen can further protect renal function with higher safety.

Objective:To investigate the incidence of postoperative complications in Chinese patients with gastric or colorectal cancer, and to evaluate the risk factors for postoperative complications.Methods:This was a national, multicenter, prospective, registry-based, cohort study of data obtained from the database of the Prevalence of Abdominal Complications After Gastro- enterological Surgery (PACAGE) study sponsored by the China Gastrointestinal Cancer Surgical Union. The PACAGE database prospectively collected general demographic characteristics, protocols for perioperative treatment, and variables associated with postoperative complications in patients treated for gastric or colorectal cancer in 20 medical centers from December 2018 to December 2020. The patients were grouped according to the presence or absence of postoperative complications. Postoperative complications were categorized and graded in accordance with the expert consensus on postoperative complications in gastrointestinal oncology surgery and Clavien-Dindo grading criteria. The incidence of postoperative complications of different grades are presented as bar charts. Independent risk factors for occurrence of postoperative complications were identified by multifactorial unconditional logistic regression.Results:The study cohort comprised 3926 patients with gastric or colorectal cancer, 657 (16.7%) of whom had a total of 876 postoperative complications. Serious complications (Grade III and above) occurred in 4.0% of patients (156/3926). The rate of Grade V complications was 0.2% (7/3926). The cohort included 2271 patients with gastric cancer with a postoperative complication rate of 18.1% (412/2271) and serious complication rate of 4.7% (106/2271); and 1655 with colorectal cancer, with a postoperative complication rate of 14.8% (245/1655) and serious complication rate of 3.0% (50/1655). The incidences of anastomotic leakage in patients with gastric and colorectal cancer were 3.3% (74/2271) and 3.4% (56/1655), respectively. Abdominal infection was the most frequently occurring complication, accounting for 28.7% (164/572) and 39.5% (120/304) of postoperative complications in patients with gastric and colorectal cancer, respectively. The most frequently occurring grade of postoperative complication was Grade II, accounting for 65.4% (374/572) and 56.6% (172/304) of complications in patients with gastric and colorectal cancers, respectively. Multifactorial analysis identified (1) the following independent risk factors for postoperative complications in patients in the gastric cancer group: preoperative comorbidities (OR=2.54, 95%CI: 1.51-4.28, P<0.001), neoadjuvant therapy (OR=1.42, 95%CI:1.06-1.89, P=0.020), high American Society of Anesthesiologists (ASA) scores (ASA score 2 points:OR=1.60, 95% CI: 1.23-2.07, P<0.001, ASA score ≥3 points:OR=0.43, 95% CI: 0.25-0.73, P=0.002), operative time >180 minutes (OR=1.81, 95% CI: 1.42-2.31, P<0.001), intraoperative bleeding >50 mL (OR=1.29,95%CI: 1.01-1.63, P=0.038), and distal gastrectomy compared with total gastrectomy (OR=0.65,95%CI: 0.51-0.83, P<0.001); and (2) the following independent risk factors for postoperative complications in patients in the colorectal cancer group: female (OR=0.60, 95%CI: 0.44-0.80, P<0.001), preoperative comorbidities (OR=2.73, 95%CI: 1.25-5.99, P=0.030), neoadjuvant therapy (OR=1.83, 95%CI:1.23-2.72, P=0.008), laparoscopic surgery (OR=0.47, 95%CI: 0.30-0.72, P=0.022), and abdominoperineal resection compared with low anterior resection (OR=2.74, 95%CI: 1.71-4.41, P<0.001). Conclusion:Postoperative complications associated with various types of infection were the most frequent complications in patients with gastric or colorectal cancer. Although the risk factors for postoperative complications differed between patients with gastric cancer and those with colorectal cancer, the presence of preoperative comorbidities, administration of neoadjuvant therapy, and extent of surgical resection, were the commonest factors associated with postoperative complications in patients of both categories.
