Objective:To compare the efficacy of body posture combined with pharmacotherapy and pharmacotherapy alone in the treatment of chronic subdural hematoma(CSDH).Methods:Firstly, retrospective case series study was conducted. Thirty cases of CSDH that had received body posture combined with pharmacotherapy at Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from December 2016 to October 2020 were studied retrospectively. Twenty-seven patients were male, and 3 patients were female. The age of patients ( M(IQR)) was 66(16) years (range:28 to 84). Nineteen patients had unilateral hematoma, and 11 patients had bilateral hematoma. All patients received pharmacotherapy and body posture therapy that was to raise their lower limbs 20 to 30 cm with leg lift pad and get abdominal compressed with customized abdominal belt in supine position. Patients were required to maintain the body posture as much as possible, with the maximum to 16 to 18 hours per day. Patients with unilateral hematoma should tilt the head to the affected side and avoid tilting it to the opposite side. For patients with bilateral hematoma, there was no need for head lateralization. Patient were treated with oral dexamethasone and atorvastatin simultaneously. The preliminary efficacy of body posture combined with pharmacotherapy was determined by hematoma improvement rate which was analyzed by Clopper-Pearson method. Then, the multi-center, prospective, randomized controlled trial had carried out in 9 medical centers from August 2020 to November 2021. The stratified block randomization method was adopted. Patients were randomized in a ratio of 1∶1 to either receive pharmacotherapy alone(the control group) or body posture combined with pharmacotherapy(the experiment group) for 3 months and followed up for 6 months. Effective treatment was defined as complete absorption of hematoma, or the hematoma volume decreased by more than 10 ml and Markwalder grading scale score had improved by more than 1 point compared to the baseline. The efficacy rate and surgery conversion rate at 3 months and recurrence at 6 months were observed. Comparison between groups was performed with paired sample t test, Mann-Whitney U test, χ2 test, corrected χ2 test, or Fisher exact probability method. Logistic regression was used to compare the effective rate and operation rate between the two groups. Results:In the respective study, 30 patients completed follow-up 13 to 353 days after treatment. At the last follow-up, the incidence of almost complete absorption or significantly absorption of hematoma (hematoma volume was significantly reduced accompanied by symptom improvement) was 93.3%. The 95% CI for the incidence that analyzed by the Clopper-Pearson method was 77.9% to 99.2%. One hundred and six patients were enrolled in the multicenter study. Fifty-five patients underwent body posture combined with pharmacotherapy. The age was 74(17) years (range:26 to 92). Thirty-nine patients were males and 16 were females. Fifty-one patients underwent pharmacotherapy alone. The age was 69(12) years (range:48 to 84). Thirty-seven patients were males and 14 were females. The length of body posture recorded in diary card was (15.7±2.3) hours(range:7.6 to 19.3 hours). The efficacy rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 83.6% (46/55) and 56.9% (29/51), respectively at 3 months. The result of the logistic regression analysis showed that the efficacy of body posture combined with pharmacotherapy group was better than that of pharmacotherapy alone group ( OR=3.88,95% CI:1.57 to 9.58, P=0.003). Surgery rate in the body posture combined with pharmacotherapy group and pharmacotherapy alone group were 5.5% (3/55) and 21.6% (11/51) respectively. The result of Logistic regression showed that the pharmacotherapy alone group was more likely to be converted to surgery ( OR=0.21,95% CI:0.05 to 0.80, P=0.023). At the 6 months, no recurrence of cases was found in the body posture combined with pharmacotherapy group. However, the recurrence rate of pharmacotherapy alone group was 6.3% (3/48), there was no significant difference between the two groups ( P>0.05). Conclusion:The effect of body posture combined with pharmacotherapy for chronic subdural hematoma is better than that of pharmacotherapy alone.

Objective:To compare the clinical characteristics of patients with cryptogenic cirrhosis and hepatitis B cirrhosis in order to provide a basis for the diagnosis of cryptogenic cirrhosis.Methods:A retrospective study was performed. The clinical data of inpatients with cryptogenic cirrhosis from 2010 to 2020 were collected from Peking University First Hospital. The clinical baseline data were analyzed. Patients with hepatitis B cirrhosis hospitalized during the same period were used as the control group, and 1:1 matching was performed according to the age range (±5 years) and the same year of admission. The basic clinical data between the groups were analyzed. The t-test, X2-test or Mann-Whitney U test was used for intergroup comparison.Results:A total of 232 cases with cryptogenic cirrhosis were collected. A total of 207 cases were collected after excluding cases with missing data, including 95 males (45.9%) and 112 females (54.1%), with a median age of 66 (57-76) years. A total of 182 pairs were matched according to the matching criteria for the control study. Compared with the hepatitis B cirrhosis group, the patients with cryptogenic cirrhosis had higher blood triglycerides (0.89 mmol/L vs. 0.80 mmol/L, P=0.002)and total cholesterol (3.73 mmol/L vs. 3.55 mmol/L, P=0.048), alanine transaminase (21.0 U/L vs. 24.5 U/L, P=0.003) and aspartate transaminase (29.5 U/L vs. 33.0 U/L, P=0.008) were lower, the prothrombin time was shorter (12.4 s vs. 13.0 s, P=0.003), and the INR was lower (1.18 vs. 1.21, P=0.015) with statistically significant differences ( P<0.05). The proportion of patients with cryptogenic cirrhosis combined with hepatocellular carcinoma (15.9% vs. 35.7%, P<0.001), hepatic encephalopathy (2.7% vs. 7.7%, P=0.034), and hepatorenal syndrome (1.6% vs. 5.5%, P=0.048),were relatively low, and the differences were statistically significant ( P<0.05). Conclusions:Cryptogenic cirrhosis at our hospital may be associated with metabolic syndrome and cannot be excluded as a cause of non-alcoholic fatty liver disease/non-alcoholic steatohepatitis in some of these patients.

Patent foramen ovale(PFO)demonstrates significant comorbidity with migraine,but its causal relationship and the efficacy of transcatheter closure remain controversial.This systematic review examines potential biomarkers and relevant imaging assessments for PFO-associated migraine,aiming to provide a theoretical foundation for clinical diagnosis and treatment.Key biomarkers include platelet activation markers,calcitonin gene-related peptide,homocysteine,and platelet-to-lymphocyte ratio.Imaging evaluations encompass right-to-left shunt grading(transthoracic echocardiography,transcranial Doppler ultrasound),cerebrovascular breath-holding index,characteristics of white matter hyperintensities,alterations in resting-state functional magnetic resonance imaging(rs-f-MRI)brain networks,in-situ thrombi detected by optical coherence tomography,and electroencephalogram(EEG)power spectral features.Research indicates that integrating biomarkers with imaging technologies enhances diagnostic discrimination and treatment outcome prediction.Current challenges include unclear causal relationships and insufficient standardization of detection methods.Future efforts require multidisciplinary collaboration to establish personalized diagnostic and therapeutic frameworks through multimodal indicators,thereby advancing precise prevention and treatment strategies for PFO-related migraine.

Objective To investigate the correlation between the level of N-terminal pro-Brain natriuretic peptide(NT-proBNP)and cardiorespiratory fitness following acute exposure to high altitude.Methods Forty-six subjects were recruited from the Second Affiliated Hospital of Army Medical University in June 2022,including 19 males and 27 females.After completing cardiopulmonary exercise test(CPET),serological detection of myocardial cell-related markers,and multiple metabolites at a plain altitude(300 meters above sea level),all subjects flew to a high-altitude location(3900 meters above sea level).Biomarker testing and CPET were repeated on the second and third days after arrival at high altitude.Changes in serum biomarker and key CPET indicators before and after rapid ascent to high altitude were compared,and the correlation between serum levels of various myocardial cell-related markers and metabolites and high altitude cardiorespiratory fitness was analyzed.Results Compared with the plain altitude,there was a significant decrease in maximal oxygen uptake after rapid ascent to high altitude[(25.41±6.20)ml/(kg.min)vs.(30.17±5.01)ml/(kg.min),P<0.001].Serum levels of NT-proBNP,Epinephrine(E),plasma renin activity(PRA),angiotensin Ⅱ(Ang Ⅱ),angiotensin-converting enzyme 2(ACE2)and leptin(LEP)significantly increased,with all differences being statistically significant(P<0.05)after acute high altitude exposure.In contrast,no statistically significant differences were observed for creatine kinase MB(CK-MB),cardiac troponin I(cTnI),myoglobin(Myo)and norepinephrine(NE)(P>0.05).Correlation analysis showed a significant negative correlation between NT-proBNP at plain altitude(r=-0.768,P<0.001)and at high altitude(r=-0.791,P<0.001)with maximal oxygen uptake at high altitude.Multivariate linear regression analysis indicated that maximal oxygen uptake at plain altitude(t=2.069,P=0.045),NT-proBNP at plain altitude(t=-2.436,P=0.020)and at high altitude(t=-3.578,P=0.001)were independent influencing factors of cardiorespiratory fitness at high altitude.Conclusion Cardiorespiratory fitness significantly decreases after rapid ascent to high altitude,and the baseline NT-proBNP level at plain altitude is closely related to cardiorespiratory fitness at high altitude,making it a potential predictor indicator for high altitude cardiorespiratory fitness.

Objective To analyze the epidemiological patterns and pathogens of clusters of diarrhea in Xicheng Distract , Beijing during 2017-2022 , in order to update the policy of prevention. Mehods Between January 2017 and December 2022, stool samples of patients and partly cooks in clusters of diarrhea were collected and tested by Real-time PCR for Rotavirus, Norovirus, Adenovirus, Sapovirus and Astrovirus. Part of ORF1/ORF2 from Norovirus positive samples were amplified using RT-PCR. PCR products were sequenced and the genetypes were determined. Results Four hundreds and one clusters of diarrheas were reported. Among them , 369 were reported in kindergartens, primary schools and secondary schools. The morbidities were 4.14, 2.13 and 0.69 per thousand, respectively. Seventy four cooks in 15 clusters of diarrhea were Norovirus positive. The rate was 8.67%. Among these pathogens, Norovirus had the largest proportion , but the trend was declining. At least three kinds of genetype of GⅡ Norovirus were detected every year. Conclusion Clusters of diarrhea mainly occurred in kindergartens, primary schools and secondary schools. Result from the increasing proportions of unknown-cause clusters of diarrhea, the testing methods and scopes of pathogens should be extended. Diverse genetypes of Norovirus coexist and alternate in Beijing. So appearance of new genetypes and recombination of existed ones of Norovirus should be closely concerned.
