Objective　To investigate the dynamic changes of psychological states and the results of delivery in pregnant women,simultaneously,study the effective way to reduce the rate of cesarean section.Methods　Through applying the self-compiled test paper,the self-evaluating state table(SCL-90)and the table of overall feeling of happiness,we assessed the psychological states of 89 pregnant women.The results were recorded at 35 and 38 weeks of gestation and 72 hours postpartum.Results　48 delivered vaginally(53.93%).4 were managed by cesarean section(46.07%),including 12 non-indicated cesarean section(29.27%).The mark of anxiety,terror and depression factors increased in the group of non-indicated cesarean section before and after dilivery compared with the group of vaginal delivery and indicated cesarean section.There was remarkable difference(P＜0.01).The value of overall feeling of happiness in the group of non-indicated cesarean section was less than that in the group of vaginal delivery.The difference was extremely significant(P＜0.001).The rdevant analysis showed that the feeling of happiness,the desire of labor and educational level were related negatively to the level of symptom during pregnancy(P＜0.01).The mode of delivery was related positively to the psychological state of pregnant women(P＜0.01).Conclusion　Non-indicated cesarean section is mainly interrelated to anxiety,terror and depression that proceed gradually during pregnancy and delivery.So it is suggested that the aimed psychological education be beneficial to decrease the rate of cesarean section.

Objective To analyze the clinical characteristics, treatments and prognosis of acute obstructive suppurative pancreatic ductitis ( AOSPD) , and to discuss its pathogenesis, diagnosis and treatment strategy. Methods 63 AOSPD cases reported in Chinese and foreign literature from June 1993 to January 2019 were collected. The sex, age of onset, etiology and potential risk factors, clinical manifestations, laboratory examinations, imaging findings, treatments and prognosis were recorded. Results The male to female ratio was 53 / 10, and the median age of onset was 59 years. The etiology and risk factors included chronic pancreatitis, pancreatic neoplasms, diabetes mellitus, history of endoscopic intervention and alcoholism before the onset of AOSPD. The main clinical manifestations were epigastric pain and fever, and sepsis and shock might occur in a few cases. The serum amylase was 13-1946 ( IU/L) at the early stage of onset and it decreased to varying degrees after treatments. Imaging examination showed that pancreatic duct dilatation was found in 54 patients and pancreatic duct stones were found in 42 patients. Pancreatic juice culture was bacteria-positive in more than 31 cases, and the common pathogenic bacteria were Enterococcus and Escherichia coli. Therapeutic methods included endoscopic pancreatic stent implantation ( n=36 ) , endoscopic nasopancreatic drainage (n=22), surgical operation (n=4) and antibiotic treatment, and the condictions in most of the patients were improved to some extent after treatments. Conclusions Older age, male, chronic pancreatic disease, history of endoscopic intervention and drinking, and diabetes mellitus were the main etiological factors of AOSPD. The clinical manifestations of AOSPD were nonspecific but could be complicated by severe complications. Imaging examination and pancreatic juice culture can help to confirm the diagnosis. Antibiotic therapy, timely endoscopic interventions and surgical procedures can improve the short-term prognosis.

Objective:To investigate the clinical efficacy of multi-point acupuncture and lavage on removing facial filling material.Methods:From May 2015 to May 2020, the Department of Plastic Surgery of Tianjin Time Plastic Aesthetic Clinic removed the filling materials from 38 patients (4 males, 34 females; 19-55 years, with average 28 years). During the operation, multi-point acupuncture were performed with an 18G needle to perforate different cavities of the fillers to press them out; with injection syringe flushing fluid was injected with a needle into the filling material area with repeated lavage through puncture points.Results:On average, 90% of the filling materials were recovered by this method, 5 cases were removed twice; follow-up for 6-12 months after operation showed that postoperative appearance was natural, and no scar and hyperpigmentation occurred; there were no cases of postoperative infection with ideal effects.Conclusions:Multi-point acupuncture and lavage treatment can remove more facial filling material; although there is also small amount of filling material left, it is not affect clinical efficacy. This method basically does not damage the surrounding normal tissue, and therefore it is worthy of clinical application.

Objective:To investigate the activation level of neutrophil extracellular trap (NET) in the bile of patients with choledocholithiasis and its clinical significance.Methods:From May 2021 to October 2022, 130 patients underwent endoscopic retrograde cholangiopancreatography (ERCP) at the Department of Gastroenterology, the First Affiliated Hospital of Anhui Medical University were enrolled. The patients were divided into choledocholithiasis group (90 cases) and non-choledocholithiasis group (40 cases), and the choledocholithiasis group was further divided into large stone group (maximum diameter >1 cm, 36 cases) and small stone group (maximum diameter≤1 cm, 54 cases). The bile samples were collected from 130 patients during operation and 16 choledocholithiasis patients with nasobiliary drainage at 24 h after operation.The levels of myeloperoxidase(MPO), neutrophilelastase(NE), and citrullinated histone H3(CitH3) in bile were detected by enzyme-linked immunosorbent assay.The levels of MPO, NE, and CitH3 were compared between choledocholithiasis group and non-choledocholithiasis group, between large stone group and small stone group, as well as between choledocholithiasis patients before ERCP and after ERCP. Mann-Whitney U test and Wilcoxon signed rank test were used for statistical analysis. Results:The levels of MPO, NE and CitH3 in the bile of choledocholithiasis group were 32.6 U/L(28.5 U/L), 30.6 ng/L(35.2 ng/L) and 0.37 μg/L(0.73 μg/L), respectively, which were all higher than those of non-choledocholithiasis group (19.9 U/L(36.4 U/L), 18.2 ng/L(27.4 ng/L), and 0.10 μg/L(0.25 μg/L)), and the differences were statistically significant ( Z=2.91, 3.20 and 3.34; P=0.004, 0.001 and 0.001). The levels of MPO, NE and CitH3 of large stone group were 47.0 U/L(49.4 U/L), 48.4 ng/L(39.5 ng/L) and 0.83 μg/L(1.08 μg/L), respectively, which were all higher than those of small stone group (29.3 U/L(17.5 U/L), 24.0 ng/L(25.8 ng/L), and 0.27 μg/L(0.45 μg/L)), and the differences were statistically significant ( Z=2.01, 3.58 and 3.63; P=0.044, <0.001 and <0.001). The levels of MPO, NE and CitH3 in the bile of choledocholithiasis patients after ERCP significantly decreased compare with those before ERCP (19.4 U/L(19.8 U/L) vs. 33.6 U/L(36.7 U/L), 12.7 ng/L(15.1 ng/L) vs. 22.7 ng/L(25.9 ng/L), 0.05 μg/L(0.12 μg/L) vs. 0.14 μg/L(0.27 μg/L)), and the differences were statistically significant ( Z=3.52, 3.30 and 3.18; all P<0.001). Conclusion:The activation level of NET in the bile of patients with choledocholithiasis increase, while the activation level of NET decrease after ERCP, which indicate that NET may be involved in the formation of choledocholithiasis.

Objective:To record stereoelectroencephalography (SEEG) data and to induce cortical electrical stimulation in children with tuberous sclerosis complex (TSC), thus exploring the epileptogenicity of different types of cortical tubers.Methods:The SEEG recording and cortical electrical stimulation data of 50 children with TSC who underwent preoperative evaluation for drug-resistant epilepsy at Epilepsy Center, Tsinghua University Yuquan Hospital from November 2016 to September 2022 were retrospectively analyzed, involving 27 boys and 23 girls with the age of (5.5±3.4) years.According to the results of 3.0T magnetic resonance imaging (3T-MRI) and computed tomography(CT), cortical tubers were classified.The incidences of electroclinical seizures, electrical seizures and seizures induced by cortical electrical stimulation in different types of tubers recorded by SEEG were analyzed, and the differences in the proportion of the above seizures among different types of tubers were compared using the Fisher′ s exact test. Results:A total of 303 cortical tubers were explored using SEEG in 50 patients.The tubers were divided into 6 types, including Type A, B, C, D and E, and focal cortical dysplasia like (FCD-like) type, among which Type E was for the first time proposed in the world.Among these explored tubers, 7 tubers had electrical seizures, and 57 tubers had electroclinical seizures.A total of 64 tubers (21.1%) were epileptogenic.The incidence of epileptogenic tubers in Type A-E and FCD-like type were 3.6%, 1.4%, 19.0%, 77.8%, 77.5%, and 90.0%, respectively. Fisher′ s exact test and Bonferroni correction were performed for pairwise comparisons( P<0.003). There was no significant difference in the incidence of epileptogenic tubes among Type A, B and C. There was significant difference in the incidence of epileptogenic tubes between Type A-C with Type D, Type E and FCD-like type, respectively.There was no significant difference in the incidence of epileptogenic tubes between Type D, Type E and FCD-like like.Electrical stimulation-induced seizures occurred in 36 cortical tubers (11.9%). The positive rate of electrical stimulation seizures in Type A-E and FCD-like type were 0.7%, 1.4%, 4.8%, 44.4%, 45.0%, and 70.0%, respectively.There was significant difference in the positive rate of electrical stimulation seizures between Type A-B and Type D, Type E and FCD-like type, respectively, so as that between Type C versus Type E and FCD-like type.No significant difference in the positive rate of electrical stimulation seizures was found between other pairwise comparisons. Conclusions:This study proposed a new classification of cortical tubers in TSC patients, and Type E is proposed for the first time in the world.SEEG records confirmed great differences in epileptogenicity indifferent types of cortical tubers.Type D, Type E and FCD-like type have higher epileptogenicity, which is of great value for the preoperative evaluation of TSC epilepsy surgery and the placement strategy of SEEG electrodes.

ObjectiveTo investigate the difference in the level of biliary calprotectin between patients with cholangiocarcinoma and those with choledocholithiasis. MethodsClinical data and bile samples were collected from 34 patients with cholangiocarcinoma and 78 patients with choledocholithiasis who were diagnosed and treated with endoscopic retrograde cholangiopancreatography in The First Affiliated Hospital of Anhui Medical University from May 2021 to September 2022. Fluorescence lateral flow immunoassay was used to measure the levels of calprotectin， hemoglobin， and lactoferrin in bile. The Mann-Whitney U test was used for comparison of continuous data between two groups， and the chi-square test was used for comparison of categorical data between two groups； the Spearman correlation test was used for correlation analysis； the DeLong test was used for comparison of the area under the ROC curve （AUC）. ResultsCompared with the choledocholithiasis group， the cholangiocarcinoma group had significant increases in the levels of calprotectin ［4 795.50 （2 286.79‍ ‍—‍ ‍20 179.73） ng/mL vs 411.16 （67.03‍ ‍—‍ ‍1 991.88） ng/mL， Z=5.572， P<0.001］ and fluoride ［115.70 （109.10‍ — ‍125.50） mmol/L vs 106.60 （98.60‍ ‍—‍ ‍114.40） mmol/L， Z=2.702， P=0.007］. The patients with cholangiocarcinoma were further divided into high cholangiocarcinoma group and low cholangiocarcinoma group， and there was no significant difference between the two groups in the level of calprotectin ［3 867.71 （2 235.66‍ — ‍26 407.40） ng/mL vs 4 795.50 （2 361.15‍ — ‍13 070.53） ng/mL， Z=0.129， P>0.05］. Biliary calprotectin level was correlated with white blood cell count， hemoglobin concentration， and lactoferrin concentration in bile （r=0.316， 0.353， and 0.464， all P<0.05）. The ROC curve analysis showed that biliary calprotectin （with a sensitivity of 79.4% and a specificity of 75.6%）， blood CA19-9 （with a sensitivity of 82.4% and a specificity of 78.2%）， and their combination （with a sensitivity of 88.2% and a specificity of 73.1%） had good sensitivity and specificity in the diagnosis of cholangiocarcinoma. ConclusionThere is an increase in the level of biliary calprotectin in patients with cholangiocarcinoma， and therefore， it might become a biomarker for the diagnosis of cholangiocarcinoma.
