This study was aimed to optimize the uniform design for effective constituents in water-soluble extractives D, E, F of traditional Chinese medicine (TCM) in Qi-Xue Bing-Zhi Fang (QXBZF) for the further validation of the ratio of different compatibility. A total of 100 SD rats were used in the study. Among them, 90 rats were given high fat feeding for 7 days. Then, stratified randomization was used. The rats were divided into the all-party group; D, E original prescription group; D, E optimized compatible group; D, E between optimized and original group; D, E optimized but anti-compatibility group; all-party group adding F; optimized compatible group adding F; QXBZF with mainly paeoniflorin accounted for 49.12% as component D, total flavonoids accounted for 30.0% as component E, total acids accounted for 32.07% in component F; the positive drug control group (Xue-Zhi-Kang, 0.108 g/kg); and the high fat model group. In addition, a blank control group (with normal diet) was set. Each group was treated with gastric perfusion according to drug compatibility proportion for 14 days. Rats were sacrificed to take blood samples for the detection of serum lipid, platelet aggregation, vasoactive substance, and inflammation level. The results showed that compared with the model group, the QXBZF D, E original prescription group and D, E optimized compatible group had significant decreasing effects on TC (P< 0.05). The lowest level of TC decreased by optimized compatible group was (3.49 ± 0.86) mmol/L. The all-party group, D, E original prescription group and optimized compatible group can inhibit the platelet with maximum aggregation rate effectively(P< 0.05, P< 0.01); while the D, E optimized but anti-compatibility group (with D, E inverse proportion) had no effect on it. All-party group and the D, E original group adding F had significant inhibition on IL-6 and IL-8 (P < 0.05, P < 0.01). The D, E original prescription group, D, E optimized compatible group and D, E between optimized and original group can ascend 6-Keto-PGF1α significantly (P< 0.05). ET-1 was decreased in the D, E optimized compatible group (P< 0.05). Other groups had no obvious effect on vascular active substances. It was concluded that different effects between the QXBZF D, E original prescription group and the D, E optimized compatible group were observed in action segment and strength. When F parts added, inhibitions of inflammation levels were enhanced at certain level.

Objective:To investigate the risk factors for delirium after intertrochanteric fracture surgery in the elderly.Methods:The data of 423 elderly patients with femoral intertrochanteric fracture were retrospectively analyzed who had been treated by closed reduction and internal fixation with proximal femoral nail antirotation (PFNA) at Department of Orthopedics, The Second Central Hospital of Baoding from December 2010 to April 2018. They were 205 males and 218 females, aged from 70 to 98 years (mean, 78.6 years). By AO classification, 239 fractures were type 31-A1, 141 ones type 31-A2, and 43 ones type 31-A3. Of them, 362 were complicated with disease of internal medicine. The interval from injury to surgery ranged from 4 to 72 hours with an average of 46.6 hours. The incidence of postoperative delirium was recorded. The risk factors were screened by univariate analysis from the hidden blood loss, gender, age, body mass index, complications, anesthesia method, preoperative preparation time and electrolyte disturbance; multivariate logistic regression analysis was used to determine the independent risk factors from the factors with P< 0.05. Results:Post-operative delirium occurred in 49 of the 423 patients (11.58%) (29 cases on the first postoperative day and 20 ones on the second postoperative day). It was not observed in the other 374 (88.42%) patients. Univariate analysis showed significant differences in the interval from injury to surgery, hidden blood loss and electrolyte disturbance between the patients with and without postoperative delirium ( P<0.05). Multivariate logistic regression analysis showed that the interval from injury to surgery >48 hours ( OR=3.386, 95% CI: 1.362 to 6.638), hidden blood loss>600 mL ( OR=10.292, 95% CI: 1.244 to 35.091) and electrolyte disturbance ( OR=4.157, 95% CI: 1.595 to 7.626) were the independent risk factors for postoperative delirium in elderly patients with intertrochanteric fracture. Conclusion:Long preoperative preparation, a large amount of hidden blood loss and postoperative electrolyte disturbance may be the risk factors for post-operative delirium in elderly patients with intertrochanteric fracture afterinternal fixation.

Objective:To evaluate the pathological features of a heart failure with preserved ejection fraction(HFpEF) model, which is established by spontaneously hypertensive rats (SHR) through high-fat diet and diabetic factors.Methods:Twenty specific pathogen-free grade(SPF grade) and 14-week-old SHR rats were randomly divided into SHR group (normal diet) and HFpEF group [high-fat diet combined with intraperitoneal injection of streptozotocin (STZ, 25 mg/kg) were used to create a diabetic complex model] with 10 rats in each group. Ten SPF and 14-week-old WKY rats with the same genetic background were set as blank control group (WKY group). All rats were fed for 8 weeks. Echocardiography was performed to measure cardiac parameters: peak velocity of early diastolic mitral inflow(E), peak velocity of late diastolic mitral inflow(A), and the early diastolic mitral annulus e′ in the same cardiac cycle, left atrial ejection fraction (LAEF), left ventricular ejection fraction (LVEF), left atrial diameter, right atrial diameter and interventricular septal thickness(IVST). Serological testing included glucose (GLU) and glycosylated serum protein (GSP); Enzyme-linked immunoassay (ELISA) testing included insulin (INS), glucagon (PG), C-peptide (CP), leptin (LEP), atrial natriuretic peptide (ANP) and B-type brain natriuretic peptide (BNP). The rat heart tissue was stained with HE, and the morphological changes of atrial/ventricular tissue were observed under an optical microscope.Results:The pathological characteristics of HFpEF was established in SHR rats fed with high fat and diabetes. Echocardiography showed that compared with the WKY group, the values of E, E/A and E/e′ in the HFpEF group were significantly increased (all P<0.01), and e′and LAEF were significantly reduced (all P<0.01). In the HFpEF group, the anteroposterior and tranverse dimensions of the left atrium and the long-axis dimension of the right atrium increased to varying degrees (all P<0.05), and the IVST was also significantly increased ( P<0.01). At the same time, atrial wall was thickened obviously, myocardial cells were disordered, and myocardial fibers were broken. Compared with the WKY group, the levels of serum markers ANP and BNP in HFpEF group were significantly increased (all P<0.01), and the levels of serum insulin-related indicators INS, PG, CP, LEP, GSP, and GLU increased to varying degrees (all P<0.01). Conclusions:The composite model established by SHR rats through high-fat diet and diabetic factors can simulate the Doppler echocardiographic changes and pathological features of HFpEF, as well as abnormal changes in serum related markers and insulin indicators.

Objective:To examine the occurrence of complications in elderly patients who have undergone radical surgery for colorectal cancer.Additionally, this study aims to identify the various risk factors associated with these complications.Methods:This study included elderly patients with colorectal cancer who underwent radical surgery at Beijing Hospital between January 2013 and December 2020.These patients were divided into two groups based on their age.In this study, we examined a total of 906 patients who underwent surgery, with 695 patients under the age of 80 and 211 patients aged 80 and above.We classified postoperative complications into two categories: medical and surgical complications.Our analysis compared comorbidities, clinicopathological factors, perioperative variables, and postoperative morbidity and mortality between the two age groups.We utilized both univariate and multivariate analyses to identify any potential risk factors for postoperative morbidity.Results:When comparing patients under 80 years old to those aged 80 or older, it was found that the latter group had a lower body mass index, worse ASA scores, and more comorbidities.Additionally, the proportion of elderly patients with right colon cancer, pT3-4, and pN+ disease was higher compared to those under 80 years old.Furthermore, the elderly patients aged 80 or older had a lower rate of laparoscopic surgery compared to those under 80 years old.The study found that elderly patients aged 80 years and older had significantly shorter operation times compared to those younger than 80 years[(191.0±70.6)min vs.(214.0±83.3)min, t=3.642, P<0.001]. However, the overall complication rate was higher in the elderly group(32.7%)than in the younger group(22.6%)( χ2=8.839, P=0.004). Upon further analysis, it was found that medical complications increased significantly(20.9% vs.7.5%, χ2=30.547, P<0.001), whereas the rate of surgical complications did not show any statistical difference(15.6% vs.16.4%, χ2=0.069, P=0.832). The mortality rate during the perioperative period was found to be significantly higher in elderly patients aged 80 years and above compared to those below 80 years(1.9% vs.0.3%, χ2=6.316, P=0.029). Further analysis revealed that age was an independent risk factor for medical complications( HR=2.822, 95% CI: 1.804-4.414, P<0.001). Laparoscopic surgery has been shown to significantly decrease surgical complications( HR=0.475, 95% CI: 0.317-0.711, P=0.001). However, if the operation time exceeds 200 minutes, there is a significant increase in surgical complications( HR=1.942, 95% CI: 1.278-2.888, P=0.002). Conclusions:The incidence of postoperative medical complications in very elderly patients with colorectal cancer who undergo radical surgery has risen, although the rate of surgical complications has remained steady.Radical surgery for elderly patients with colorectal cancer is both safe and feasible, but it is important to prioritize the prevention and management of medical complications.
