Objective     To evaluate the effect of intraoperative fluid infusion volume on postoperative pulmonary complications (PPCs) in patients after minimally invasive endoscopic esophageal carcinoma resection. Methods     From June 2019 to August 2021, 486 patients undergoing elective minimally invasive endoscopic esophagectomy for esophageal cancer were retrospectively screened from the electronic medical record information management system and anesthesia surgery clinical information system of West China Hospital of Sichuan University. There were 381 males and 105 females, with a median age of 64.0 years. Taking the incidence of pulmonary complications within 7 days after operation as the primary outcome, the correlation between intraoperative fluid infusion volume and the occurrence of PPCs within 7 days was clearly analyzed by regression analysis. Results    The incidence of pulmonary complications within 7 days after surgery was 33.5% (163/486). Regression analysis showed that intraoperative fluid infusion volume was correlated with the occurrence of PPCs [adjusted OR=1.089, 95%CI (1.012, 1.172), P=0.023], especially pulmonary infection [adjusted OR=1.093, 95%CI (1.014, 1.178), P=0.020], and pleural effusion [adjusted OR=1.147, 95%CI (1.007, 1.306), P=0.039]. Pulmonary infection was significantly less in the low intraoperative fluid infusion group [<6.49 mL/(kg·h), n=115] compared with the high intraoperative fluid infusion group [≥6.49 mL/(kg·h), n=371] (18.3% vs. 34.5%, P=0.023). Intraoperative fluid infusion volume was positively associated with death within 30 days after surgery [adjusted OR=1.442, 95%CI (1.056, 1.968), P=0.021]. Conclusion     Among patients undergoing elective minimally invasive endoscopic esophageal cancer resection, intraoperative fluid infusion volume is related with the occurrence of PPCs within 7 days after the surgery, especially pulmonary infection and pleural effusion, and may affect death within 30 days after the surgery.

Objective     To evaluate the association between pressure-controlled ventilation-volume guaranteed (PCV-VG) mode and volume-controlled ventilation (VCV) mode on postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung resection. Methods     A retrospective cohort analysis of 329 patients undergoing elective thoracoscopic lung resection in West China Hospital of Sichuan University between September 2020 and March 2021 was conducted, including 213 females and 116 males, aged 53.6±11.3 years. American Society of Anesthesiologists (ASA) grade wasⅠ-Ⅲ. The patients who received lung-protective ventilation strategy during anesthesia were divided into a PCV-VG group (n=165) and a VCV group (n=164) according to intraoperative ventilation mode. Primary outcome was the incidence of PPCs during hospitalization. Results     A total of 73 (22.2%) patients developed PPCs during hospitalization. The PPCs incidence of PCV-VG and VCV was 21.8% and 22.6%, respectively (RR=0.985, 95%CI 0.569-1.611, P=0.871). Multivariate logistic regression analysis showed that there was no statistical difference in the incidence of PPCs between PCV-VG and VCV mode during hospitalization (OR=0.846, 95%CI 0.487-1.470, P=0.553). Conclusion     Among patients undergoing thoracoscopic lung resection, intraoperative ventilation mode (PCV-VG or VCV) is not associated with the risk of PPCs during hospitalization.

Objective To evaluate biomechanical strength of locking compression plate (LCP) for fixation of periprosthetic proximal femur fractures (PPFF). Methods Eight matched pairs of Vancouver type B1 adult cadaveric PPFF specimens were fixed with the LCP and the inverted distal femoral less invasive stabilization system (LISS), respectively. Four bicortical locking screws (LCP group) and four unicortical locking screws were used to the length of prosthesis stem, and four double cortical locking screws were used to fix the distal end of the fracture in two groups, the distance from the locking screws to the fracture were also equal. The maximum bending load, maximum bending displacement, bending stiffness, maximum torque, maximum torsional angle and torsional stiffness of two groups in four-point bending test and torsion test were compared and analyzed. Results The maximum bending load, maximum bending displacement and bending stiffness of LCP group were all larger than those of LISS group, but the difference was not statistically significant (P>0.05). The maximum torque, maximum torsional angle and torsional stiffness of LCP group were obviously larger than those of LISS group，and there was a statistical difference between two groups (P<0.05). Conclusions The stiffness of anti-torsion with LCP is significantly better than that with LISS. Consequently, LCP has better biomechanical stability for PPFF.

Objective To explore the treatment of children with EB virus infection accompanied by facial paralysis. Method The clinical data of a child with EB virus infection accompanied by facial paralysis was analyzed retrospectively, and the related literature were reviewed. Results A 2-year-old boy was admitted to hospital due to fever and mouth askew for 4 days. After admission, he was confirmed to have EB virus infection and viremia by serology and polymerase chain reaction, and then treated with acyclovir. The symptoms of facial paralysis and EB viremia disappeared completely 14 days after antiviral treatment. There was no recurrence in the short-term follow-up. Interestingly, the literature analysis shows that there is still limited evidence for the antiviral treatment by acyclovir in children with acute infection of EB virus associated with facial paralysis. Conclusion Antiviral treatment may be beneficial to EB viremia with facial paralysis.

Objective To study the clinical and the epidemiological features of hospitalized children with influenza virus infection. Methods Two hundred and fifty-three inpatients with laboratory-confirmed influenza virus infection from 1999 to 2008 were reviewed for analyzing the clinical and epidemiological characteristics. Type A and B influenza viruses in the nasopharyngeal aspirates were detected by immunofluorescence assay. Mann-Whitney U test were performed for comparing the median age and the length of hospitalization. Chi-square test was performed for comparing the proportion of patients with fever and cough. Results Among 253 hospitalized children aged between 5 days and 127 months, 182 (71.9%) were boys and 71 (28. 1%) were girls. The median age was 18 months. Fifty-three cases were infants younger than 6 months. 95 cases were children aged between 6 months and 2 years, 85 cases were aged between 2 years and 5 years and 20 cases were older than 5 years. The diagnosis of influenza-related admission included pneumonia (190 cases), bronchitis (49 cases) and upper respiratory tract infection (14 cases). Eleven cases developed febrile convulsion, 6 cases had acute exacerbation of asthma and 3 cases had concomitant viralencephalitis. Twenty-nine cases had basic diseases. Cough and fever were the most common symptoms. Two hundred and thirty-eight cases presenting cough and 209 case presenting fever. Sixty-seven percent (140/209) had high fever with body temperature higher than 39 ℃. The average duration of fever was (5. 0 ±2. 9) days. Fever and cough were both more common in children older than6 months (X2 = 22. 895,P<0. 01; X2 = 16. 992,P<0. 01, respectively). Febrile convulsion occurred in children older than 2 years. Fifteen point five (39/251) developed leukocytopenia. Conclusions Children younger than 5 years old are at high risk of influenza-related hospitalization. We should emphasize influenza vaccination in previously healthy children aged between 6 months and 5 years and children with underlying diseases.

Objective To observe the effect of platelet-rich plasma(PRP)gel on tendon-bone healing following tendon allograft reconstruction of anterior cruciate ligament(ACL).Methods Bilateral ACL reconstructions using Achilles tendon allografts were performed in 24 New Zealand white rabbits matured skeletally.One knee joint was pretreated with the allograft PRP gel(served as experimental group),while the contralateral knee joint was free from treatment with PRP(served as control group).The reconstructions were assessed histologically,immunohistochemically and biomechanically at 2,6 and 12 weeks.Results At 2 and 6 weeks,Burak scores of experimental group were higher than control group.At 12 weeks,the grafts showed a mature zone of fibrocartilage in experimental group but mature scar tissues on the tendon-bone surface.Immunohistochemistry demonstrated early higher expression of VEGF in experimental group than control group and continually higher expression of TGF-β1 in experimental than control group.In contrast,the grafts of the controls group revealed the development of mature scar tissue resembling Sharpey fibers spanning the tendon-bone interface.At 2 and 6 weeks,the biomechanical analysis revealed the limit load of(15.3±2.9)N and(33.2±6.9)N respectively in experimental group,which were significantly higher than(7.9±1.4)N and(23.7±4.9)N in control group (P ＜ 0.05).Conclusion Application of PRP is the potential means to enhance the earlier healing of the allograft tendon-bone.
