Objective To explore the efficacy of bilateral facial muscle training combined with visual electromyography biofeedback on facial nerve function recovery in patients with idiopathic facial nerve palsy. Methods Patients with idiopathic facial nerve palsy admitted to Shanghai Fifth People’s Hospital, Fudan University from July 2022 to July 2024 were selected and randomly divided into a control group and an intervention group. The control group received conventional physical factor therapy, while the intervention group received bilateral facial muscle training combined with visual electromyography biofeedback therapy based on the control group’s regimen. After 20 treatment sessions, the total effective rate, the House-Brackmann (H-B) facial nerve grading system, the Sunnybrook Facial Grading System (SFGS) score, and the average value ratio of maximal amplitudes of bilateral frontalis and zygomaticus muscles were compared between the two groups. Results A total of 90 patients were included, 45 in each group. After 20 treatment sessions, the total effective rate was significantly higher in the intervention group than in the control group (84.4% vs 75.6%, P＝0.003). Compared with the control group, the intervention group demonstrated a significantly lower H-B grade (P＝0.003) and a higher SFGS score (P＝0.001). The average value ratios of maximal amplitudes of the affected versus healthy side frontalis (P＝0.013) and zygomatic (P＝0.022) muscles were higher in the intervention group than in the control group. Conclusions Bilateral facial muscle training combined with visual electromyography biofeedback is an effective approach for treating idiopathic facial nerve palsy, effectively promoting the recovery of facial nerve function, and improving facial symmetry and facial muscle function.

Objective:To investigate the influencing of preoperative biliary drainage on surgery-related complications after pancreaticoduodenectomy.Methods:The retrospective case-control study was conducted. The clinical data of 267 patients with periampullary space-occupying lesion who were admitted to Beijing Friendship Hospital of Capital Medical University from January 2016 to July 2020 were collected. There were 166 males and 101 females, aged 61 (range, 54?84)years. Observation indicators: (1) comparison of preoperative situations in patients with and without preoperative biliary drainage; (2) comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage; (3) methods and efficacy of preoperative biliary drainage; (4) factors influencing surgery-related complications after pancreaticoduodenec-tomy. Measurement data with normal distribution were represented as Mean± SD, and comparison between groups was conducted using the t test. Measurement data with skewed distribution were represented as M(rang) or M( Q1, Q3), and comparison between groups was conducted using the Mann-Whitney U test. Count data were described as absolute numbers or percentages, and comparison between groups was conducted using the chi-square test. Univariate analysis was conducted using the corresponding statistical methods based on data type. Multivariate analysis was conducted using the Logistic stepwise regression model. Results:(1) Comparison of preoperative situations in patients with and without preoperative biliary drainage. Of the 267 patients, there were 104 cases with preoperative biliary drainage and 163 cases without preoperative biliary drainage. Cases with malignant tumor, cases with borderline tumor, cases with chronic pancreatitis were 89, 13, 2 in patients with preoperative biliary drainage, versus 111, 41, 11 in patients without preoperative biliary drainage, showing significant differences in pathology type between them ( χ2=10.652, P<0.05). (2) Comparison of intraoperative and postoperative situations in patients with and without preoperative biliary drainage. There was no significant difference in operation time, volume of intra-operative blood loss, postoperative complications, grade B pancreatic fistula, grade C pancreatic fistula, biliary leakage, abdominal or gastrointestinal bleeding, incidence of abdominal infection, white blood cell count at postoperative day 1, white blood cell count at postoperative day 3, neutrophil-to-lymphocyte ratio at postoperative day 1, neutrophil-to-lymphocyte ratio at postoperative day 3, C-reactive protein-albumin ratio at postoperative day 1, C-reactive protein-albumin ratio at post-operative day 3, duration of hospital stay between the 104 patients with preoperative biliary drainage and the 163 patients without preoperative biliary drainage ( P>0.05). (3) Methods and efficacy of preoperative biliary drainage. Of the 104 patients with preoperative biliary drainage, there were 40 cases receiving endoscopic nasobiliary drainage with drainage time as (12±2)days, there were 38 cases receiving percutaneous transhepatic cholangial drainage with drainage time as (7±1)days, and there were 26 cases receiving endoscopic retrograde biliary drainage with drainage time as (19±2)days. The total bilirubin, direct bilirubin, aspartate transaminase, alanine aminotrans-ferase in 104 patients were (223±18)μmol/L, (134±11)μmol/L, (112±10)U/L, (160±16)U/L before biliary drainage and (144±13)μmol/L, (84±8)μmol/L, (79±8)U/L, (109±12)U/L after biliary drainage, showing significant differences in the above indicators ( t=3.544, 3.608, 2.523, 2.509, P<0.05). (4) Factors influencing surgery-related complications after pancreatocoduodenectomy. Results of multi-variate analysis showed that operation time was an independent factor influencing surgery-related complications after pancreaticoduodenectomy ( odds ratio=1.005, 95% confidence interval as 1.002?1.008, P<0.05). Conclusions:Preoperative biliary drainage does not increase the incidence of complications related to pancreaticoduodenectomy in patients with periampullary space-occupying lesion. Operation time is an independent factor influencing postoperative surgery-related complications.

Objective:To investigate the effect of the duration of preoperative biliary drainage on postoperative complications after pancreaticoduodenectomy.Methods:The clinical data of 102 patients with benign and malignant hepatopancreatic ductal periampullary tumors who underwent pancreaticoduodenectomy and preoperative biliary drainage in Beijing Friendship Hospital, Capital Medical University from January 2016 to July 2020 were retrospectively analyzed. According to the median duration of preoperative biliary drainage, the patients were divided into short-term drainage group (≤ the median duration of biliary drainage) and long-term drainage group (> the median duration of biliary drainage). The general data, the effect of biliary drainage, inflammation-related indicators and postoperative complications were compared between the two groups. Multivariate logistic regression was used to screen the risk factors related to the postoperative severe complications.Results:Of the 102 patients, 68 (66.7%) were males and 34 (33.3%) were females, with a median age of 63 years (43-80 years). The median duration of preoperative biliary drainage was 14 d. There were 68 patients in short-term drainage group and 34 patients in long-term drainage group. There were no statistically significant differences in age, gender, body mass index (BMI), hypertension, diabetes mellitus, surgery history of upper abdominal, American Society of Anesthesiologists (ASA) grade, carcinoembryonic antigen, carbohydrate antigen 125, alpha-fetoprotein, prothrombin time, pancreaticojejunostomy method, operation time, and pathological type between the two groups (all P > 0.05). However, patients in long-term drainage group had higher conversion rate, more blood loss and longer hospital stay compared with those in short-term drainage group (all P < 0.05). Before biliary drainage, alanine aminotransferase (ALT) level in short-term drainage group was higher than that in long-term drainage group ( Z = -2.59, P = 0.009), and there were no statistically significant differences in aspartate aminotransferase (AST), albumin (ALB), total bilirubin (TB) and direct bilirubin (DB) levels between the two groups before biliary drainage (all P > 0.05). After biliary drainage, DB in short-term drainage group was higher than that in long-term drainage group ( Z = -3.34, P = 0.001), and there was no statistically significant difference in ALT, AST, ALB, TB levels between the two groups (all P > 0.05). There were no statistically significant differences in the levels of white blood cells, neutrophils, lymphocytes and the ratio of neutrophils to lymphocytes between the two groups on the 1st and 3rd day after the operation (all P > 0.05). The total incidence of postoperative related complications in short-term drainage group and long-term drainage group was 63.2% (43/68), 70.6% (24/34), respectively, and the difference was statistically significant ( χ2 = 0.54, P = 0.461); the incidences of bile leakage, abdominal or gastrointestinal bleeding, intra-abdominal infection, delayed gastric emptying, all grades of pancreatic leakage, grade B and C pancreatic leakage were not statistically different between the two groups (all P > 0.05); the incidence of severe postoperative related complications in short-term drainage group was higher than that in long-term drainage group [27.9% (19/68) vs. 8.8% (3/34), χ2 = 4.90, P = 0.027]. Multivariate logistic regression analysis showed that the long-term preoperative biliary drainage was an independent protective factor for postoperative severe complications (long-term drainage vs. short-term drainage: OR = 0.253, 95% CI 0.066-0.975, P = 0.046), while BMI ( OR = 1.174, 95% CI 0.986-1.398, P = 0.071) and pathological type (benign or borderline vs. malignant tumor: OR = 0.247, 95% CI 0.043-1.419, P = 0.117) were not independent influencing factors for postoperative severe complications. Conclusions:Short-term biliary drainage (≤14 d) is a risk factor for postoperative severe complications in patients with hepatopancreatic ductal periampullary tumor undergoing preoperative biliary drainage. Preoperative biliary drainage time is not associated with postoperative total complications, pancreatic leakage, bile leakage, abdominal or gastrointestinal bleeding, intra-abdominal infection, delayed gastric emptying.

Objective To study the relationship between behavioral problems and family environment in preschool-age children. Methods Children between 4-6 years of age in the kindergartens of Zhongshan city were randomly selected. Child Behavior Checklist (CBCL) was used to assess the behavioral problems in children, and self-designed general situation question-naire and Family Environment Scale-Chinese Version (FES-CV) were applied to evaluate the family environment. Results A total of 3445 children were enrolled and 29.87%children showed behavioral problems. There were signiifcant differences in the scores of feeling expression, family conlfict, intelligence, recreation, organization and control between children with and without behavior problems (P<0.001). The scores of feeling expression, intelligence, recreation, organization and control were signiif-cantly higher and the score of family conlfict was lower in healthy children in comparison with children with behavior problems. Through multivariate logistic regression, it was suggested that female (OR=2.04), non-urban population (township OR=1.45, rural OR=1.51), non-local Zhongshan resident (OR=1.39), father’s low educational level (technical secondary school OR=1.77, junior high school OR=2.17, primary school and below OR=3.24), discipline styles (indulgent OR=1.47, mixed OR=1.37), family conlfict (OR=1.13) were independent risk factors for behavioral problems (P<0.05). Mother’s age over 30 (OR=0.74) or over 40 (OR=0.46), feeling expression (OR=0.94) and intelligence (OR=0.87) were independent protective factors for behavioral prob-lems (P<0.05). Conclusions Behavioral problems in preschool-age children are closely related to family environment, which needs to be paid more attention.
