Objective To observe the value of ultrasound radiomics for distinguishing early and middle-late stage endometrial cancer(EC).Methods A total of 294 women with EC were retrospectively enrolled,including 196 in early stage and 98 in middle-late stage.The patients were randomly divided into training set(n=206)and validation set(n=88)at the ratio of 7∶3.Clinical data were compared between different stages,and a clinical model was constructed.Radiomics features were extracted and screened based on ultrasound data,and radiomics models were constructed with logistic regression(LR),random forest(RF),support vector machine(SVM),Gaussian naive Bayes(GNB)and extreme gradient boosting(XGBoost),respectively.Finally,a clinical-radiomics model was constructed.The value of each model for distinguishing early and middle-late stages EC was observed.Results Significant differences of age of consultation,menstrual disorders,abdominal pain and proportion of menopause were found between patients with early and middle-late stage EC(all P＜0.05).Among these 5 radiomics models,RF model had the highest area under the curve(AUC)for distinguishing early and middle-late stage EC.Pairwise comparison of clinical model,RF radiomics model and clinical-RF radiomics model showed that significant differences of AUC were found between each 2 models(all P＜0.05),and clinical-RF radiomics model had the highest AUC.Conclusion Ultrasound radiomics based on RF were helpful for distinguishing early and middle-late stage EC,and better diagnostic efficacy could be obtained through combining with clinical data.

As a narrow concept, the service target of psychotherapy is patients with mental disorders, hence, psychotherapy practice in clinical field should be carried out under the framework of psychiatric medicine. It needs to meet the characteristics of diagnosis basis, evidence basis, guideline recommendation, objective evaluation, and strong operability. Meanwhile, the development of psychotherapy is increasingly showing a trend of integration. This article proposes the concept of symptom-based psychotherapy decision-making under the framework of psychiatric medicine, using cognitive behavioral therapy skills as an example, aiming to improve the efficiency, efficacy, and standardization of clinical work, and fulfill the requirements of psychotherapy under the framework of psychiatric medicine. By this way, we expect to inspire professional readers to think and investigate more about psychotherapy decision-making.

Objective:To investigate the clinical effect of esophagofundostomy combined with pericardial devascularization in the treatment of upper gastrointestinal hemorrhage caused by portal hypertension.Methods:The clinical data of 108 patients with portal hypertension admitted to the Affiliated Hospital of Inner Mongolia Medical University from Feb 2009 to Feb 2015 were analyzed. Among them 42 patients underwent esophagofundostomy combined with pericardial devascularization as the study group, and 66 patients underwent pericardial devascularization only as the control group. All patients presented with splenomegaly or hypersplenism; the spleen was routinely removed during the operation.Results:The difference of operation time between the study group and the control group was statistically significant [(157±41) min vs. (143±27) min, t=2.81, P<0.05]. The improvement in the esophagogastric varices in the study group within 6 months was significantly better than that in the control group( Z=2.47, P<0.05). In addition, the rebleeding rates of varicose veins within 1, 3 and 5 years in the study group was 2%, 5% and 10%, while that in the control group was 15%, 21% and 26% (χ 2=5.49, 4.27, 4.31, all P<0.05). Conclusions:Esophagofundostomy combined with pericardia devascularization achieves complete devascularization and low rebleeding rate.

Objective To compare the scalp nerve block versus local infiltration of incision for in-tracranial aneurysm clipping under general anesthesia. Methods Fifty-seven American Society of Anesthe-siologists physical statusⅠorⅡpatients of both sexes, aged 18-64 yr, scheduled for elective intracranial aneurysm clipping under general anesthesia, were divided into 3 groups ( n=19 each) using a random num-ber table method:control group ( group C) , scalp nerve block group ( group S) and local infiltration of in-cision group ( group I) . Anesthesia was induced by intravenously injecting propofol, sufentanil and cisatra-curium. Bilateral supraorbital nerve (2 ml), supratrochlear nerve (2 ml), zygomaticotemporal nerve (2 ml), auriculotemporal nerve (2 ml), greater occipital nerve (3 ml), lesser occipital nerve (3 ml) and the third occipital nerve ( 1 ml) blocks were performed with 0. 75％ ropivacaine after tracheal intubation in group B. Local infiltration of incision was carried out with 0. 75％ ropivacaine 15 ml in group I. Anesthesia was maintained by intravenously infusing propofol and remifentanil to maintain bispectral index value at 40-60. The fluctuation range of mean arterial pressure and heart rate was not more than 20％ of the baseline, and vasoactive agents were administered when necessary. Oxycodone 0. 1 mg∕kg was intravenously injected at 30 min before the end of surgery to perform preemptive analgesia. When visual analogue scale score>3 with-in 48 h after surgery, oxycodone 2 mg was intravenously injected as rescue analgesic, and administration was repeated when necessary ( at an interval>15 min) . The intraoperative consumption of propofol, remifen-tanil and vasoactive agents was recorded. Arterial blood samples were collected before anesthesia induction and at 3, 12, 24, 48 and 72 h after surgery for determination of serum interleukin-6 ( IL-6) , IL-10 and C-reactive protein ( CRP ) concentrations by enzyme-linked immunosorbent assay. The time of the first postoperative requirement for oxycodone and consumption of oxycodone within 48 h after surgery were recor-ded. The development of adverse reactions such as postoperative fever, nausea and vomiting, dizziness, respiratory depression, pruritus, local anesthetic intoxication, subcutaneous hematoma, and scalp infec-tion was also recorded. Results Compared with group C, the intraoperative consumption of remifentanil and requirement for nicardipine were significantly decreased, the concentration of serum IL-6 was decreased at 3 h after surgery, the concentration of serum CRP was decreased at 12 h after surgery, the concentration of serum IL-10 was increased at 12 and 24 h after surgery, the time of the first postoperative requirement for rescue analgesia was prolonged, the consumption of oxycodone was reduced, and the incidence of nausea and vomiting was decreased in group B, and the intraoperative consumption of remifentanil was significantly reduced in group I (P<0. 05). Compared with group I, the intraoperative consumption of remifentanil was significantly reduced, the requirement for nicardipine was decreased, the concentration of serum IL-6 was decreased at 3 h after surger-y, the concentration of serum CRP was decreased at 12 h after surgery, the concentration of serum IL-10 was in-creased at 12 and 24 h after surgery, the time of the first postoperative requirement for rescue analgesia was pro-longed, the consumption of oxycodone was reduced, and the incidence of nausea and vomiting was decreased in group B (P<0. 05). Conclusion Compared with local infiltration of incision, scalp nerve block is helpful in carrying out anesthetic model of low-consumption opioids and in maintaining intraoperative hemodynamics stable and is more helpful in inhibiting perioperative inflammatory and pain responses when used for the patients under-going intracranial aneurysm clipping under general anesthesia.

BACKGROUND:Reperfusion injury salvage kinase (RISK) pathway plays an important role in protective mechanism against ischemia reperfusion injury (IRI) induced by both ischemic pre-and post-conditioning. Many researches have been carried out on RISK pathway mechanism underlying ischemic post-conditioning conferring cardioprotection against IRI;however, there is less research about its effect on IRI in the skeletal muscle.
OBJECTIVE:To investigate the protective effect of an optimized protocol of ischemic post-conditioning on IRI in rat skeletal muscle and its underlying mechanism.
METHODS:Eighteen male Sprague-Dawley rats were equivalently randomized into IRI, ischemic post-conditioning and control groups. Rats were given occlusion or disocclusion of the right femoral artery of the right lower limb. Subsequently, the IRI group rats were subjected to 24 hours of reperfusion;the ischemic post-conditioning group immediately given 4 cycles of 30 seconds reperfusion/30 seconds ischemia, followed by 24 hours of reperfusion;the control group given no intervention.
RESULTS AND CONCLUSION:Hematoxylin-eosin staining showed that in the ischemic post-conditioning group, the morphology of muscle fibers changed little, with fewer inflammatory lesions and milder edema compared with the IRI group. The infarct size with TTC staining in the ischemic post-conditioning group was smaller than that in the IRI group. Western blot analysis revealed that the expressions of phospho-Akt and phosphorylated endothelial nitric oxide synthase-S1177 were significantly increased, but the expression of phosphorylated type endothelial nitric oxide synthase-Thr495 was much decreased in the ischemic post-conditioning group compared with the IRI group. The measurement of mitochondrial permeability transition pore opening with Ca2+induction showed that the absorbance values in the ischemic post-conditioning group were significantly lower than those in the IRI group (P<0.05). These results indicate that ischemia-reperfusion injury can be improved by applying an optimal protocol of ischemic post-conditioning in rat skeletal muscle. The underlying mechanism may be associated with the activation of RISK signaling pathway to inhibit opening of mitochondrial permeability transition pore, thereby contributing to the enhanced tolerance to IRI in rat skeletal muscle.

Objective With multi?center investigation, to assess the life quality of patients with maintained hemodialysis (MHD) in Liaoning Province and to explore the relationship among the mineral metabolism, the life quality of the patients with MHD, and the repeated hospitalization within the latest three years. Methods 1192 patients with hemodialysis (at least 3 months) from January to March in 2015 at ten blood purification centers in Liaoning Province were selected for the cross?————————sectional survey. The Kidney Health?related Quality of Life (HRQOL) version 1.3 was used to evaluate the MHD patients' life quality. The total length of hospitalization was divided into four groups: 0 days, 3 to 15 days, 16 to 30 days and above 30 days. Results When serum calcium value ranged from 2.1 to 2.5 mmol/L, kidney?disease component summary (KDCS), mental component summary (MCS), physical component summary (PCS) and SF?36+KDCS corresponded to a higher value (P<0.05). When serum phosphorus value ranged from 1.13 to 1.78 mmol/L, KDCS and SF?36+KDCS corresponded to a higher value (P<0.05). When the calcium phosphorus product value ranged from 40.68 to 49.94, MCS corresponded to a higher value (P<0.05). KDCS showed a linear correlation with age (P<0.001), dialysis age, serum calcium (less than or equal to 2.5 mmol/L) (P<0.05); PCS showed a linear correlation with age (P<0.001) and dialysis age (P<0.05); SF?36+KDCS showed a linear correlation with age (P<0.001), and serum calcium (less than or equal to 2.5 mmol/L) (P<0.05), while age and dialysis age were negatively correlated. The hospitalization days showed a linear correlation with age, dialysis age (P<0.001) and serum phosphorus, calcium phosphorus product value (P<0.05), while dialysis age and calcium phosphorus product value were negatively correlated. Among different groups of total hospitalization days in three years, age, hemodialysis age, serum calcium, serum phosphorus, calcium?phosphorus product value and quality of life values were all statistically significant (P<0.05). Conclusions The life quality of patients with MHD were correlated with serum calcium, phosphorus, calcium and phosphorus product value, iPTH, dialysis age and age, while age and dialysis age were of negative correlation. The total number of hospitalization days in 3 years was closely linearly correlated with age and dialysis age, significantly correlated with serum phosphorus, calcium and phosphorus product value, while dialysis age, calcium and phosphorus product value were in a negative correlation. The total number of hospitalization in 3 years was correlated with the patients' age, dialysis age, serum calcium, serum phosphorus, calcium and phosphorus product value and quality of life.
