Objective To explore the clinical effect of high intensity focused ultrasound(HIFU)combined with transcatheter arterial chemoembolization(TACE)in the treatment of primary liver cancer.Methods A total of 106 patients with primary liver cancer were divided into two groups:50 cases were treated with TACE,and the other 56 were treated with combination of HIFU and TACE.The changes of AFP levels and the size of tumors after three months treatment were analyzed and compared with each other.The survival rates for one,two and three years were calculated with Kaplan-Meier method and compared between the two groups.Results In the two groups,AFP decreased significantly after treatment,but the combined group was superior to the other in AFP decrease.In the combined group,the 1-,2-and 3-year survival rates were higher than those in the TACE group with 82.3%,60.8%and 39.2% vs 68.0%,42.6%and 21.0%respectively(P＜0.01).No serious complications were seen,such as burn of skin,bleeding,gastrointestinal perforation. Conclusion The use of HIFU combined with TACE in the treatment of patients with primary liver cancers is feasible and safe.The combined group is superior to simple TACE for the management of primary liver cancers,and the former is more effective in decreasing AFP level and improving survival rates.

As China has not yet established a sound regional trauma treatment system and standardized trauma centers at all levels, the trauma treatment capability in China is poorer than that in the developed countries. At present, Shaanxi Province has not established a regional trauma treatment system and standardized trauma centers at all levels. Based on the analysis of the characteristics of geography, population and social environment in Shaanxi Province, the authors explore the concept of the trauma treatment system and the construction of trauma centers at all levels in Shaanxi Province on the platform of the trauma center of Shaanxi People's Hospital ( Grade I trauma center) . The authors clarify the respective hardware facilities, team structure, treatment process and quality control goals, training and management system of professional trauma teams in trauma centers at all levels, so as to provide reference for improving the overall level of trauma treatment in Shaanxi Province.

Objective:To investigate the curative effect of decompression with reserved superficial temporal artery for treatment of severe traumatic brain injury (sTBI).Methods:A retrospective case-control study was conducted to analyze the clinical data of 265 patients with sTBI who underwent decompressive craniectomy in Shaanxi Provincial People's Hospital from July 2016 to December 2019. Among them, 152 were males and 113 were females, with the age of 33-72 years [(50.1±12.8)years]. On admission, the Glasgow Coma Score (GCS) was 3-8 points [(5.7±1.4)points]. A total of 135 patients were treated with reserved superficial temporal artery decompression after admission (observation group) and 130 patients were treated with conventional decompression without deliberately preserving the superficial temporal artery (control group). The amount of intraoperative scalp bleeding, scalp healing time, cerebrospinal fluid incision leakage, healing degree and postoperative craniocerebral CT angiography (CTA) were compared between the two groups.Results:All patients were followed up for 7-15 days [(12.4±2.5)days]. The amount of intraoperative scalp bleeding was (15.4±4.5)ml in observation group and (65.2±4.7)ml in control group ( P<0.01). The healing time was (7.1±1.1)days in observation group and (9.5±2.3)days in control group ( P<0.01). There were 5 patients (3.7%) with cerebrospinal fluid incision leakage in observation group compared to 21 patients (16.2%) in control group ( P<0.01). There were 114 patients with Grade A healing in observation group compared to 91 patients in control group ( P<0.05). Based on the postoperative craniocerebral CTA, the superficial temporal artery was intact and the blood supply was normal in observation group, while the main trunk of the superficial temporal artery was disconnected from the zygomatic arch segment and the blood supply was incomplete in control group. Conclusions:For patients with sTBI, decompressive craniectomy with reserved superficial temporal artery can promote the healing of the scalp. Moreover, keeping the superficial temporal artery can significantly reduce the amount of bleeding during operation, reduce postoperative scalp healing time and incidence of cerebrospinal fluid incision leakage and assist cerebral blood perfusion.

Objective To evaluate the efficacy and safety of epalrestat, an aldose reductase inhibitor, and epalrestat plus methylcobalamine on diabetic peripheral neuropathy, as compared with methylcobalamine. Methods A total of 444 subjects with diabetic neuropathy were enrolled in the study, and divided into methylcobalamine group ( n= 145 ) , epalrestat group ( n = 143 ) , and methylcobalamine combined with epalrestat group ( n = 156 ) . Therapeutic efficacay was assessed in terms of clinical symptoms and physical examinations by using Michigan Neuropathy Screening Instrument ( MNSI ) , and electrophysiological assessments. Results After 4 to 12-weeks′treatment, symptoms and signs of neuropathy ( using MNSI ) are significantly improved in the three groups ( P<0. 01). The mean changes of MNSI ( questionnaire) score from baseline were higher in epalrestat group and methylcobalamine combined with epalrestat group as compared with that of methylcobalamine group(P<0. 05), but no difference was detected in the change of MNSI ( physical examination ) score from baseline among three groups. After treatment for 12 weeks, motor nerve conduction velocity ( MNCV ) was significantly improved in epalrestat group and methylcobalamine combined with epalrestat group(P<0. 05), but no difference was detected in MNCV at 12 week among three groups(P>0. 05). Conclusion Epalrestat is effective and safe in the treatment of diabetic neuropathy. Furthermore, epalrestat is more efficacious in ameliorating symptoms and MNCV of neuropathy than methylcobalamine. However, while no improved efficacy is shown with the combined treatment.

Objective:To investigate the clinical features and risk factors of multiple organ dysfunction syndrome (MODS) caused by wasp sting.Methods:A retrospective cohort study was conducted to collect the general data of wasp sting patients who had a clear history of wasp sting disease and clinical manifestations from June 2016 to December 2020 and were first diagnosed as wasp sting in hospital. Patients with hematological diseases, malignant tumors, severe liver and kidney dysfunction, cardiac insufficiency, and patients who had received hormone therapy before admission were excluded. Patients who were unable to obtain effective laboratory results due to hemolysis or other reasons within 48 h of admission were also excluded. The white blood cell count (WBC), neutrophil count (NEU), lymphocyte count (LYM), hemoglobin count (HB), myoglobin (Mb/MYO), activated partial thromboplastin time (APTT), albumin (ALB), K, Na, and Cl of the blood samples collected within 48 h after admission were recorded. Patients were divided into the MODS group and non-MODS group according to whether MODS occurred during hospitalization. Uni- and multivariate analysis were used to analyze the factors affecting the occurrence of MODS in wasp sting patients during hospitalization, and the receiver operating characteristic (ROC) curve was plotted to evaluate the predictive effect of myoglobin level on the occurrence of MODS in wasp sting patients during hospitalization.Results:Mb, WBC, NEU, APTT and serum potassium in the MODS group [3890.00 (1416.90-4057.00) ng/mL, (21.99 ± 8.18) × 10 9/L, (19.61 ± 7.33)× 10 9/L, (93.75 ± 45.77) s, and (4.99 ± 0.95) mmol/L] were significantly higher than those in the non-MODS group [73.50 (34.30-264.20) ng/mL, (13.40 ± 4.14)× 10 9/L, (11.18±4.73)× 10 9/L, (37.00 ± 17.16) s, and (4.05 ± 0.56) mmol/L] (all P < 0.05); blood chlorine and ALB [(101.50 (98.25-105.00) mmol/L and (35.36 ± 6.44) g/L)] were significantly lower than those in the non-MODS group [(105.00 (103.00-107.00) mmol/L and (40.71 ± 5.48) g/L)] (all P < 0.05). Multivariate logistic regression analysis showed that NEU ( OR = 0.729, 95% CI: 0.542~0.981), Mb ( OR = 0.999, 95% CI: 0.998~1.000), and APTT ( OR = 0.951, 95% CI: 0.921~0.982) were independent risk factors for MODS in wasp sting patients. ROC curve analysis showed that NEU, Mb and APTT could be used to evaluate the occurrence of MODS in wasp sting patients. Among them, Mb had the highest predictive value (AUC = 0.950, 95 % CI: 0.891~0.982). The optimal cutoff value of Mb for predicting the occurrence of MODS in wasp sting patients was 515.30 ng/mL, and the corresponding sensitivity and specificity were 90.62% and 87.23%, respectively. Conclusion:Mb is an independent risk factor for MODS in wasp sting patients, which can be used as a good predictor of MODS in wasp sting patients.

Objective:To analyze the influencing factors of achieving textbook outcome (TO) after pancreaticoduodenectomy (PD) in patients with pancreatic ductal adenocarcinoma, and to construct a nomograph model to explore its predictive value in TO.Methods:The clinical data of 205 patients with pancreatic ductal adenocarcinoma treated by PD in Henan University People's Hospital from January 2019 to December 2022 were analyzed retrospectively, including 88 males and 117 females with the age of (61.3±9.8) years old. Patients were divided into two groups based on whether they achieved TO after surgery: TO group ( n=113) and non-TO group ( n=92). Clinical data such as age, gender, intraoperative blood loss, operation time, blood transfusion volume, pancreatic CT value, and tumor differentiation degree were collected. Logistic regression analysis screened the influencing factors of PD postoperative TO and built a nomogram model. The performance of the nomogram model was evaluated using receiver operating characteristic (ROC) curve, calibration diagram, and decision curve analysis. Results:Multivariate logistic regression analysis showed that the higher the degree of tumor differentiation was in patients with pancreatic ductal adenocarcinoma (high differentiation to medium differentiation: OR=7.20, 95% CI: 1.20-43.28; high differentiation to low differentiation: OR=16.55, 95% CI: 2.01-136.11), CT value>38.45 Hu ( OR=0.29, 95% CI: 0.13-0.65), blood transfusion volume ≤350 ml ( OR=8.05, 95% CI: 2.94-22.01) and operative time ≤407.5 min ( OR=10.88, 95% CI: 3.90-30.41), the easier it was to achieve TO after PD (all P<0.05). Based on the above influencing factors, a nomogram model of the postoperative effect of PD on TO was established, and the consistency index of this column graph model was 0.863 (95% CI: 0.816-0.911). The sensitivity and specificity of ROC curve were 0.804 and 0.752, respectively. The calibration diagram showed that the calibration curve fits well with the ideal curve, and the decision curve showed that the model had obvious positive net benefit. Conclusion:The degree of tumor differentiation, CT value, blood transfusion volume, and operation time are independent influencing factors for the achievement of TO after PD in patients with pancreatic ductal adenocarcinoma, and the nomogram model constructed based on which has good predictive performance for TO.

Objective:To analyze the effect of sarcopenia on the prognosis of patients with hepatocellular carcinoma (HCC) after laparoscopic radical resection.Methods:Clinical data of 165 patients with HCC undergoing laparoscopic radical resection in Henan University People's Hospital from January 2018 to December 2021 were retrospectively analyzed, including 122 males and 43 females, aged (55.5±11.4) years. Patients were divided into sarcopenia group ( n=79) and control group (non-sarcopenia, n=86) according to the skeletal muscle index. The survivals were analyzed using the Kaplan-Meier method, and were compared by the log-rank test. Univariate and multivariate Cox regression were utilized to analyze the effect of sarcopenia on the prognosis of HCC after laparoscopic radical surgery. Results:The 1- and 3-year cumulative survival rates of control group were 96.4% and 81.2%, which were higher than those of the sarcopenia group (83.2% and 48.9%, respectively, χ2=19.67, P<0.001). The 1- and 3-year recurrence-free survival (RFS) rates of control group were 88.4% and 66.1%, which were higher than those of sarcopenia group (70.9% and 37.7%, respectively, χ2=18.80, P<0.001). Multivariate Cox regression analysis showed that the risk of recurrence ( HR=1.35, 95% CI: 1.20-1.59, P<0.001) and the risk of death ( HR=2.21, 95% CI: 1.23-3.41, P=0.001) after laparoscopic radical resection for HCC in patients with sarcopenia rises compared to non-sarcopenic patients. Conclusion:Sarcopenia is a risk factor for the survival and recurrence of HCC after laparoscopic radical surgery.
