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 investigate the changes in serum levels of endothelin-1 (ET-1) and connective tissue growth factor (CTGF) in patients with atrial fibrillation (AF) and their value for predicting recurrence of AF after radiofrequency ablation (RFCA). METHODS: Sixty-six patients with paroxysmal AF (PaAF) and 72 with persistent AF (PaAF) admitted in our hospital were recruited as AF group and 80 patients with sinus rhythm as the control group, and in all the participants, serum levels of ET-1 and CTGF were measured using ELISA and Western blotting. From 6 patients with AF and 6 with sinus rhythm undergoing cardiac surgery in our hospital, tissue samples of the right atrial appendage were taken intraoperatively for observation of structural changes of the cardiomyocytes, myocardial fibrosis and expression of ET-1 and CTGF protein. In AF group, the patients receiving RFCA were followed up for 6 months following the procedure for assessment of the outcomes. RESULTS: Compared with the control patients, the patients with AF showed obvious damages of the cardiomyocyte structure and myocardial fibrosis. Serum levels of ET-1 and CTGF levels were significantly higher in PaAF and PeAF groups than in the control group, and were higher in PeAF group than in PaAF group. In the patients with AF, serum ET-1 and CTGF levels were positively correlated with left atrial diameter (LAD) (P < 0.05), and ET-1 was positively correlated with CTGF levels (P < 0.05). In patients with postoperative AF recurrence, the serum levels of ET-1 and CTGF were significantly higher than those in patients without recurrence; serum ET-1 and CTGF levels before and after the operation were positively correlated with the recurrence of PeAF, and elevated serum levels of ET- 1 and CTGF were identified by logistic regression analysis as independent risk factors for postoperative recurrence of PeAF. CONCLUSION Serum levels of ET-1 and CTGF are significantly elevated in AF patients in positive correlation with AF duration. ET-1 and CTGF levels are higher in AF patients with postoperative recurrence, and they both have predictive value for recurrence of PeAF following RFCA.

OBJECTIVES: To investigate the clinical treatment outcomes and the changes of the outcomes over time in extremely preterm twins in Guangdong Province, China. METHODS: A retrospective analysis was performed for 269 pairs of extremely preterm twins with a gestational age of <28 weeks who were admitted to the department of neonatology in 26 grade A tertiary hospitals in Guangdong Province from January 2008 to December 2017. According to the admission time, they were divided into two groups: 2008-2012 and 2013-2017. Besides, each pair of twins was divided into the heavier infant and the lighter infant subgroups according to birth weight. The perinatal data of mothers and hospitalization data of neonates were collected. The survival rate of twins and the incidence rate of complications were compared between the 2008-2012 and 2013-2017 groups. RESULTS: Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of severe asphyxia and smaller head circumference at birth (P<0.05). The mortality rates of both of the twins, the heavier infant of the twins, and the lighter infant of the twins were lower in the 2013-2017 group compared with the 2008-2012 group (P<0.05). Compared with the 2008-2012 group, the 2013-2017 group (both the heavier infant and lighter infant subgroups) had lower incidence rates of pulmonary hemorrhage, patent ductus arteriosus (PDA), periventricular-intraventricular hemorrhage (P-IVH), and neonatal respiratory distress syndrome (NRDS) and a higher incidence rate of bronchopulmonary dysplasia (P<0.05). CONCLUSIONS There is a significant increase in the survival rate over time in extremely preterm twins with a gestational age of <28 weeks in the 26 grade A tertiary hospitals in Guangdong Province. The incidences of severe asphyxia, pulmonary hemorrhage, PDA, P-IVH, and NRDS decrease in both the heavier and lighter infants of the twins, but the incidence of bronchopulmonary dysplasia increases. With the improvement of diagnosis and treatment, the multidisciplinary collaboration between different fields of fetal medicine including prenatal diagnosis, obstetrics, and neonatology is needed in the future to jointly develop management strategies for twin pregnancy.

OBJECTIVES: To assess the growth of preterm infants up to a corrected age of 24 months, and to understand the growth trend and pattern of preterm infants. METHODS: A preterm infant follow-up database was established based on the Internet Plus follow-up system. A total of 3 188 preterm infants who were born from April 2018 to April 2021 were enrolled. Their length, weight, and head circumference were recorded at birth and at the corrected ages of 1, 3, 6, 12, 18, and 24 months. The preterm infants were grouped by perinatal factors. The growth curves of these infants were plotted and compared with the International Fetal and Newborn Growth Consortium for the 21st Century (INTERGROWTH-21st) standard and World Health Organization (WHO) standard. RESULTS: The weight, length, and head circumference curves of each group of preterm infants grouped by various perinatal factors all rose rapidly within the corrected age of 6 months, but the growth rate slowed down after the corrected age of 6 months. Based on the actual age for the groups of preterm infants with different gestational ages (<28 weeks, 28-31 CONCLUSIONS The physical growth rate of preterm infants is faster within the corrected age of 6 months, and the growth rate slows down after the corrected age of 6 months. Preterm infants with a smaller gestational age need longer time to catch up in weight and head circumference. More attention should be paid to the physical growth of extremely preterm infants, extremely low birth weight infants, and small-for-gestational-age infants.

Objective To evaluate the effectiveness and security of Botulinum toxin type A (BTX-A) in treating interstitial cystitis /bladder pain syndrome,and also the effect of different site injection.Methods Sixty-nine consecutive BPS/IC patients from October 2011 to February 2016 were divided into three groups randomly,including control group (group A) and treatment group (group B and group C).There were 5 males and 64 females,with age from 23 to 66 years old (average 44.5 years old).Twentythree patients (1 male and 22 females,aged from 23 to 69 years old,with mean age of 44.6 years old) in control group (group A) underwent hydrodistention.Twenty-four patients (2 males and 22 females,aged from 27 to 65 years old,with mean age of 42.8 years old) in group B underwent BTX-A detrusor combined triangle injection plus hydrodistention.Twenty-two patients (2 males and 20 females,aged from 30 to 68 years old,with mean age of 44.3 years old) in group C underwent BTX-A triangle injection alone plus hydrodistention.The parameters such as daytime frequency,nocturia,visual analogue scale/score (VAS),functional cystemetric volume (FCV),post-void residual volume (PVR),QOL score,maximal bladder capacity (MBC),interstitial cystitis symtom index (ICSI),interstitial cystitisproblem index (ICPI),Qmax,and Hamilton anxiey scale (HAMA) score between pre-treatment and 1,3,6 and 9 months after therapy in the three groups were compared.Results There were no serious complications observed in the three groups.All parameters 1 month after therapy were obviously superior to that of pretreatment.The efficacy in control group decreased significantly 3 months after treatment except nocturia (3.0 vs.5.0),daytime frequency(7.0 vs.14.0)and Q (14.0 ml/s vs.13.0 ml/s).However,all parameters in research groups except PVR were still obviously superior to pretherapy.The parameters except Q and nocturia in group B had statistically significant difference from contemporaneous group A (all P ＜ 0.05).However,the parameters except Q nocturia and somatic anxiety score in group C had statistically significant difference from contemporaneous group A (all P ＜ 0.05).VAS (2.0 vs.3.0) and somatic anxiety score (6.0 vs.10.0) in group B were superior to group C (all P ＜ 0.05).When it came to 6 months after therapy,urinary frequence and urgency and pain symptoms were the same to pretherapy and all parameters had no statistically significant difference between pretherapy and after therapy in group A(all P ＞ 0.05).But all parameters except PVR in research group was still superior to pretherapy.the parameters except PVR,Q and QOL in group B had statistically significant difference from contemporaneous group A (all P ＜ 0.05).However,The parameters except PVR,Q MBC,ICSI and QOL in group C had statistically significant difference from contemporaneous group A (all P ＜ 0.05).Meanwhile,efficacy in group B was better than group C in term of ICPI (6.0 vs.8.0) and somatic anxiety score (7.0 vs.10.0) (all P ＜ 0.05).The efficacy decreased significantly 9 months after treatment in both group B and C,with no statistically significant difference compared with that of pretreatment.ICSI(10.0 vs.13.0),ICPI(9.0 vs.13.0),QOL(5.0 vs.6.0)in group B,and QOL(5.0 vs.6.0)in group C had statistically significant difference compared with the contemporary parameters in group A.ICSI(10.0 vs.12.0),MBC(285.0 ml vs.237.5 ml) in group B was better than that in group C (P ＜ 0.05).Conclusions Symptoms in IC/BPS patients can be alleviated significantly by detrusor BTX-A injection plus hydrodistention.Quality of life can be improved remarkably and HAMA scores can be reduced significantly after treatment.Thus,it's an effective therapeutic mnethod for IC/BPS,and detrusor combined triangle injection can provide a better effect than single triangle injection.

Fluorescence intraoperative cholangiography (IOC) is a potential alternative for identifying anatomical variation and preventing iatrogenic bile duct injuries by using the near-infrared probe indocyanine green (ICG).However,the dynamic process and mechanism of fluorescenceIOC have not been elucidated in previous publications.Herein,the optical properties of the complex of ICG and bile,dynamic fluorescence cholangiography and iatrogenic bile duct injuries were investigated.The emission spectrum of ICG in bile peaked at 844 nm and ICG had higher tissue penetration.Extrahepatic bile ducts could fluoresce 2 min after intravenous injection,and the fluorescence intensity reached a peak at 8 min.Inaddition,biliary dynamics were observed owing to ICG excretion from the bile ducts into the duodenum.Quantitative analysis indicated that ICG-guided fluorescence IOC possessed a high signal to noise ratio compared to the surrounding peripheral tissue and the portal vein.Fluorescence IOC was based on rapid uptake of circulating ICG in plasma by hepatic cells,excretion of ICG into the bile and then its interaction with protein molecules in the bile.Moreover,fluorescence IOC was sensitive to detect bile duct ligation and acute bile duct perforation using ICG in rat models.All of the results indicated that fluorescence IOC using ICG is a valid alternative for the cholangiography of extrahepatic bile ducts and has potential for measurement of biliary dynamics.
