Objective To study on the correlation of VEGF,HSP 70,NBNA score and neonatal asphysia. Methods Using ELISA to detect the expression level of VEGF,HSP 70 in mild asphyxia group,severe asphyxia group and control group. The expression level of VEGF ,HSP 70and the correlation between NBNA score and asphyxia were compared. Results The expression levels of VEGF ,HSP 70 in both mild and severe asphyxia groups were significantly statistically higher than the control group(P<0.05). The severe asphyxia group had even higher VEGF,HSP 70 levels than the mild asphyxia group(P<0.05).The expression level of VEGF,HSP 70 are negatively correlated with the 7 th,14 th,28th-day NBNA score (r=-0.712,-0.629,-0.493;r=-0.621,-0.506,-0.016 ;P < 0.05).The area curve(AUC)for VEGF,HSP 70 leves to predicted respectively were 0.873 (95%CI 0.771~0.892,P<0.05)and 0.815(95%CI 0.729~0.871,P<0.05). Conclusions VEGF,HSP 70 lev-els in umbilical cord blood are closely related to neonatal asphyxia.The more severe the asphyxia ,the higher the expression level of VEGF and HSP 70,and the lower the NBNA score.

Objective:To understand the current situation of mood disorders in patients with thoracic and lumbar osteoporotic fractures and to preliminarily explore its influencing factors.Methods:A cross-sectional survey method was used to select 212 patients with thoracic and lumbar osteoporotic fractures from Department of Orthopedics, West China Hospital, Sichuan University, from January 2018 to September 2020 as the research subjects. The general information questionnaire, Huaxi Emotional-distress Index, Pittsburgh Sleep Quality Index (PSQI) and pain Visual Analogue Scale (VAS) were used to investigate them.Results:The incidence of mood disorders in patients with thoracic and lumbar osteoporotic fractures was 10.38% (22/212). The results of multivariate regression analysis showed that age, days of injury, PSQI score and pain VAS score were the influencing factors of emotional disturbance in patients with thoracic and lumbar osteoporotic fractures ( t values were -3.72-7.66, all P<0.05). Conclusions:Patients with thoracic and lumbar osteoporotic fractures have mood disorders. Age, injury days, PSQI score and VAS score are related to the occurrence of mood disorders in patients with thoracic and lumbar osteoporotic fractures. More attention should be payed to the influencing factors of mood disorders in patients,and timely measures should be taken for individualized intervention.

Objective:To explore the surgical technique and efficacy of pure retroperitoneoscopic extravesical standardized seeable (P.R.E.S.S.) technique for bladder cuff excision (BCE).Methods:Ninety five patients with UTUC from five domestic centers (30 cases from Changzheng Hospital, 21 cases from Peking University First Hospital, 20 cases from Yuhuangding Hospital, 21 cases from Dalian Medical University affiliated No.2 Hospital and 3 cases from General Hospital of Eastern Theater Command)between August 2017 and December 2020 were retrospectively analyzed. There were 57 males and 38 females with a mean age of (67.7±10.0) years and median tumor size of 3.0 cm. All patients underwent pure retroperitoneoscopic radical nephroureterectomy with a single surgical position and four (36 cases) or five (59 cases) trocar layout according to the surgeon’s prefer habit and experience. The demographics of the two groups were the age of [(66.3±11.2)years vs. (68.6±9.1)years], male/female ratio of (25/11 cases vs. 32/27 cases), body mass index of [(25.0± 3.0)kg/m 2 vs. (24.8±3.4)kg/m 2], tumor maximum diameter of [2.8(1.6, 3.5)cm vs. 3.0(2.0, 4.0)cm], left/right side tumor of(19/17 cases vs. 34/25 cases), T 1-2/T 3-4/Tis stage of(25/10/4 cases vs. 49/10/0 cases), and multifocal tumors of(3 cases vs. 2 cases), and the difference was not statistically significant( P>0.05). On the other hand, the differences of hydronephrosis of the operated kidney(13 cases vs. 39 cases, P=0.004), and tumor location (in renal pelvis or calyx or upper/middle/lower ureter being 23/9/4 cases vs. 35/4/20 cases, P=0.005), were statistically significant. The umbilical artery cord was used as anatomical landmark in the process of P. R.E.S.S. bladder cuff excision. The pelvic floor and extraperitoneal space around the ureter were expanded, the bladder wall was opened to form pneumovesicum, and a sufficient bladder cuff resection and exact bladder cuff closure was performed. Perioperative outcomes and follow-up data were analyzed, and the clinical outcomes between the four and five trocars were compared to evaluate the impact of trocar layout on the surgical outcomes. Results:There were 91(95.8%) cases successfully undergoing P. R.E.S.S. BCE technique, with one case converted to open BCE due to bleeding and three cases converted to distal ureter Hem-o-lok clipping because of poor exposure. Median operative time was 180(125, 230)min, and estimated blood loss was 100(50, 100)ml. The overall complication rate was 10.5%(10/95), including 2 cases(2.1%) of intraoperative bleeding, with 1 case treated by transfusion (400 ml), the other case converted to open surgery without transfusion. There were 8 cases of postoperative complications(8.4%), including 7 cases of Clavien-Dindo grade Ⅱ(3 cases of secondary hemorrhage, one case for each of drug allergy, acute renal insufficiency, blood creatinine increased to 490 μmol/L, or lung infection with lymphatic leakage), 1 case of grade Ⅲa(intestinal obstruction treated with insertion of the intestinal obstruction catheter under local anesthesia), and all these patients were discharged smoothly. The difference between the four and five trocars was not statistically significant in the following variables, including the rate of surgical conversion(8.3% vs. 1.7%), estimated intraoperative blood loss(100 ml vs. 60 ml), ratio of intraoperative lymph node dissection (25.0% vs.20.3%), P. R.E.S.S. bladder cuff excision success rate(91.7% vs.98.3%), the incidence of intraoperative and postoperative complications (13.8% vs.8.5%), pT 1-2/pT 3-4/pTis stage(22/11/3 cases vs.37/19/3 cases) and the proportion of recurrence or metastasis(8.3% vs.3.4%)(all P>0.05). However, the differences in the operation time(190 min vs.170 min, P=0.011)and postoperative hospital stay(5 d vs.6 d, P=0.005) were statistically significant. Conclusions:P. R.E.S.S. bladder cuff resection technique is safe and feasible during the procedure of pure retroperitoneoscopic radical nephroureterectomy by a single surgical position and facilitates seeable adequate bladder cuff excision by establishing an enlarged pelvic lateral extraperitoneal space and pneumovesicum. Five-trocar technique is more suitable for patients with lower ureteral tumors but may be associated with a longer postoperative hospital stay compared with the four-trocar technique.

Objective:To investigate the efficacy and safety of plasma exchange(PE) in the treatment of autoimmune hemolytic anemia in children.Methods:The data from 8 hospitals in China during November 2014 to April 2017 were collected, and the clinical characteristics of PE in children with AHA were analyzed retrospectively.Results:A total of 21 children with AHA were included in the study, including 17 cases from PICU and 4 cases from pediatric kidney ward, with 11 boys and 10 girls, and the median age was 3.64(0.25, 11.10)years old, and median hospital stay was 12(4, 45)days.There were 15 cases(71.4%) with infection, 2 cases(9.5%)with autoimmune diseases, 4 cases(19.0%) with unknown.Consciousness disturbance occurred in 4 patients before replacement and recovered to normal after PE.The volume of blood decreased in two cases(9.5%) and completely relieved.There were 20 cases of anemia (95.2%), 15 cases were normal after PE, and 5 cases were improved.Jaundice occurred in 18 cases (85.7%), 12 cases were normal after PE, 6 cases were improved.Hepatosplenomegaly was found in 11 cases, 10 cases were normal after PE, 1 case was improved.After PE, the hemoglobin and red blood cell count increased, while the total bilirubin, indirect bilirubin, urea nitrogen and lactate dehydrogenase decreased, there were significant differences between pre-and post-replacement ( P<0.05). Only 1 case had allergic reaction, which was improved after symptomatic treatment, and PE was continued.After PE, 2 cases (9.5%) had complete remission, 16 cases (76.2%) had partial remission and 3 cases (14.3%) had been discharged. Conclusion:PE therapy can obviously improve the clinical symptoms and laboratory indexes of children with AHA who have failed to respond to conservative treatment.It can be used as a treatment measure for children with severe AHA and has a good safety.

Objective To analyze the disease burden of multidrug-resistant tuberculosis (MDR-TB) in China and regions with different income levels in the world from 1990 to 2019. Methods Using the Global Burden of Disease Study 2019 (GBD2019) results, the changes of the disease burden of MDR-TB in China and regions with different income levels in the world were described and analyzed using the Joinpoint Regression Program 4.8.0.1 software. Results From 1990 to 2019, the age standardized incidence, mortality and DALY rates in China and other areas with different income levels in the world basically showed a trend of first rising and then decreasing at the turning point of the late 20th century and early 21st century, except for low-income areas where the age standardized incidence rate showed an overall upward trend. In 2019, the incidence rate, mortality and DALY rate of MDR-TB in China were 9 times, 6.67 times and 6.89 times higher than those in high-income areas, respectively. The incidence rate in China was 6 times lower than that in low and middle-income areas, while the mortality and DALY rate in China were 26 times and 32.53 times lower than those in low-income areas, respectively. The age standardized incidence, mortality rate and DALY rate of MDR-TB in men were higher than those in women. Risk factors for the burden of MDR-TB disease included alcohol consumption, smoking, and high fasting blood glucose. Conclusion From 1990 to 2019, there are significant regional and gender differences in the disease burden of multidrug-resistant tuberculosis in China and regions with different income levels in the world. Multidrug-resistant tuberculosis is still a major challenge for tuberculosis control in the world. It is necessary to develop more effective control strategies and health care systems to deal with multidrug-resistant tuberculosis.
