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 analyze the attributable burden of active smoking on the deaths of cancer in inhabitants aged 30 years and above in Zhejiang Province.Methods:Comparative risk assessment approach in the Global Burden of Disease Study was used with the data from Zhejiang Adult Tobacco Surveillance System and Death Monitoring Surveillance System in 2020, and population attributable fraction (PAF), years of life lost (YLL), work of potential years of life lost (WPYLL) attributed to smoking on the deaths of cancer in inhabitants aged 30 years and above in Zhejiang Province were calculated with a linear regression model.Results:In 2020, there were 81 536 cancer deaths aged 30 years and above in the surveillance areas of Zhejiang Province, of which 24 518 were attributed to active smoking (PAF: 30.07%, attributable mortality rate: 55.04/100 000). The YLL was 553 078 person-years, with a standardized YLL rate of 12.40‰, and the WPYLL was 56 606 person-years. Among various cancer types, laryngeal cancer had the highest smoking-attributable PAF (44.75%), while lung cancer accounted for the most significant number of attributable deaths and life loss, with an age-standardized YLL rate of 4.65‰.Conclusions:Active smoking is a significant risk factor for cancer mortality in Zhejiang Province, with lung cancer posing the most significant disease burden. It is urgent to advance tobacco control legislation, strengthen targeted interventions, and promote early cancer screening to reduce the disease burden associated with smoking-related cancers effectively.

In recent years， NOD-like receptor protein 3 （NLRP3） inflammasome in tumors has become a research hotspot， especially in melanoma， colorectal cancer， lung cancer， and breast cancer， and more and more evidence has shown that inflammation plays a role in the development， progression， angiogenesis， and invasion of cancer. Hepatocellular carcinoma （HCC） is the most common type of primary liver cancer， and there are still controversies over the role of NLRP3 inflammasome in the development and progression of HCC. Therefore， this article reviews the potential impact of NLRP3 inflammasome in the progression of HCC and its mechanism of action in anticancer therapy， and it is believed that NLRP3 inflammasome can be used as an effective therapeutic target for HCC patients.

Traumatic supraorbital fissure syndrome (TSOFS) is a symptom complex caused by nerve entrapment in the supraorbital fissure after skull base trauma. If the compressed cranial nerve in the supraorbital fissure is not decompressed surgically, ptosis, diplopia and eye movement disorder may exist for a long time and seriously affect the patients′ quality of life. Since its overall incidence is not high, it is not familiarized with the majority of neurosurgeons and some TSOFS may be complicated with skull base vascular injury. If the supraorbital fissure surgery is performed without treatment of vascular injury, it may cause massive hemorrhage, and disability and even life-threatening in severe cases. At present, there is no consensus or guideline on the diagnosis and treatment of TSOFS that can be referred to both domestically and internationally. To improve the understanding of TSOFS among clinical physicians and establish standardized diagnosis and treatment plans, the Skull Base Trauma Group of the Neurorepair Professional Committee of the Chinese Medical Doctor Association, Neurotrauma Group of the Neurosurgery Branch of the Chinese Medical Association, Neurotrauma Group of the Traumatology Branch of the Chinese Medical Association, and Editorial Committee of Chinese Journal of Trauma organized relevant experts to formulate Chinese expert consensus on the diagnosis and treatment of traumatic supraorbital fissure syndrome ( version 2024) based on evidence of evidence-based medicine and clinical experience of diagnosis and treatment. This consensus puts forward 12 recommendations on the diagnosis, classification, treatment, efficacy evaluation and follow-up of TSOFS, aiming to provide references for neurosurgeons from hospitals of all levels to standardize the diagnosis and treatment of TSOFS.

Objective : To investigate the establishment of smoke-free environments in medical and healthcare institutions in Zhejiang Province, so as to provide the evidence for improving the implementation of the tobacco control policy in medical and healthcare institutions. Methods: Health administrative sectors and public health institutions at provincial, city and county levels, secondary and tertiary medical institutions, and community health service/township health centers in Zhejiang Province were enrolled. The status of institutional establishment of smoke-free environments was investigated through concealed photography and consulting medical service guides by the assigned the third-party professional investigation company in 2021. The layout of smoke-free environments and indoor smoking were assessed according to the Criteria for Scoring Smoking-free Medical and Healthcare Institutions. Results: Totally 547 medical and healthcare institutions were enrolled in this undercover investigation, including 102 health administrative sectors, 209 public health institutions, 146 secondary and tertiary medical institutions, and 90 community health service/township health centers. The gross mean scores of establishment of smoke-free environments were 83.41±12.19 among all medical and healthcare institutions, 82.02±10.73, 85.56±9.70 and 83.18±12.59 among province-, city- and county-level medical and healthcare institutions, respectively, and the gross mean scores of establishment of smoke-free environments were 82.60±12.27, 85.79±10.74, 80.89±13.85, 82.27±11.62 scores among health administrative sectors, public health institutions, secondary and tertiary medical institutions and community health service/township health centers, respectively. There were 315 institutions with no smoking signs at entrances (57.59%), 255 institutions posting no smoking signs ( 46.62% ), 245 institutions assigning two and more types of health education materials for tobacco control ( 44.79% ), 110 institutions with outdoor smoking areas ( 51.16% ), 66 secondary and tertiary medical institutions with smoking cessation clinics ( 45.20% ) and 354 institutions with carpet smoking bans in indoor places ( 64.72% ). Conclusions The overall establishment of smoke-free environments is satisfactory among medical and healthcare institutions in Zhejiang Province. Nevertheless, improving the coverage of no smoking signs and health education of tobacco control, promoting the standardized construction of smoking cessation clinics and establishing a long-action tobacco control mechanism are still needed.

Objective:To establish a 10-year comparison table of cerebrovascular function score and first stroke risk, and to provide a new method for screening of high-risk population of stroke.Methods:In the beginning of 2003, a cohort for studing stroke risk factors in those aged 40 years and over was established in a community of Shanghai by cluster sampling. The common risk factors of stroke were investigated with a unified questionnaire, and the cerebrovascular function (cerebral vascular hemodynamic indexes, CVHI) was measured. The baseline study was completed from April to June 2003 and December 2004 to January 2005, respectively. The incident of first stroke and all cause of death were followed up year by year. The follow-up period was up to December 31, 2014. The 10-year incidence of first stroke was calculated according to the baseline score of cerebrovascular function, and the score-risk control table was established to estimate 10-year first stroke risk in each score group. The role of cerebrovascular function score in stroke was also estimated.Results:The follow-up term of 10 565 participants was (10.26±2.00) years, and 350 patients had first stroke during the follow-up. The trend 10-year incidence of first stroke both in men and women was significantly increased with the decrease of the score of cerebrovascular function (trend χ2=296.125, P<0.01). As the 10-year risk of first stroke was higher than 5% and higher than 10%, the corresponding CVHI score was lower than 70 and 40 points in males and lower than 30 and 20 points in females. When the scores of cerebral vascular function were divided by every 25 points, incidence of first stroke in each group from top to bottom was 1.9%, 4.7%, 10.8%, 15.2% in males and 1.6%, 4.4%, 4.8%, 11.4% in females, respectively. As compared to the top, the relative risk (95% CI) of first stroke in the lower groups was 2.61(1.67-4.07), 6.46(4.22-9.89), 9.74(6.53-14.52) for males and 2.82(1.93-4.12), 3.15(1.99-4.99), 8.12(5.65-11.68) for females, respectively. Multivariate analysis showed that the factors being selected into the regression equation were cerebrovascular function score, age, hypertension history, stroke family history and smoking history, among which the role of cerebrovascular function score was the strongest. Conclusion:The risk of first stroke increases significantly with the decrease of cerebrovascular function score, which can be used to assess the 10-year risk of first stroke.

Objective To investigate the severity of allogenic rejection after partial liver transplantation (PLTx) with different graft weight to recipient liver weight (GW/RLW).Methods The full-size liver transplantation (group A),GW/RLW ＞33％ PLTx (group B) and GW/RLW ＜ 30％ PLTx (group C) were set up using BN rats and Lewis rats as donors and recipients,respectively.All recipients were observed for 28 days.The Banff RAI grading,survival rate,jaundice and body weight recovery were evaluated to determine the severity of acute allogeneic rejection.Two PLTx groups,group B1 (GW/RLW＞33％) and group C1 (GW/RLW＜30％),were established to assess the mRNA level of IL-2,GranzymeB,Perforin and CD3 48 h and 7 days postoperatively.Additionally,the mRNA level of B7-H1,the ratio of Ki67 + hepatocytes and the liver enzymes were also assessed 7 days postoperatively.Results All recipients in group C died within 22 days postoperatively,presenting with severe lymphocytic infiltration and vascular endothelialitis.All recipients in group A and group B survived until the end of observation time.All recipients in group A survived and presented with a mild lymphocytic infiltration and rare vascular endothelialitis.Group B presented with moderate lymphocytic infiltration and moderate vascular endothelialitis.The Banff RAI grading in group C was significantly higher than that in group A and group B (P ＜ 0.05).In accordance with the result of histology and survival rate,group B and group C presented with earlier jaundice and lower body weight recovery than that of group A (P＜0.05).As compared with group B1,group C1 presented with higher mRNA levels of Perforin,GranzymeB,IL-2 and CD3,higher level of liver enzymes and heavier liver graft weights.Besides,the mRNA level of immunosuppresive molecule B7-H1 in group C1 was lower than that of group B1.However,there was no significant difference in the ratio of Ki67 + hepatocytes between group B1 and group C1.Conclusion The allogenic liver rejection may be enhanced by reducing the GW/RLW.

Objective: To compare the accumulative scores of cerebrovascular hemodynamic parameters (CVHP) in different populations and to analyze the relationship between the change of accumulative scores and the risk of stroke. Methods: A total of 10 565 participants aged 40 years and above were selected from a cluster sampling community-based population. Their risk factors were investigated and CVHP was evaluated. The CVHP scores were accumulated by a unified approach, and the incidence of stroke was followed up. The participants were grouped into health adult, single factor exposure, multiple-factor exposure, and newly developed stroke during the follow-up period. The differences of CVHP accumulative scores and the change law among the 4 groups were compared respectively according to age and sex. Results: The accumu-lative scores of the mean (SD) CVHP in the health adult, single factor exposure, multiple-factor exposure, and newly developed stroke groups were 86.44 (20.69), 72.07 (28.10), 60.82(34.64), and4.01 (29.36) in men respectively, and they were 83.95 (22.19), 67.97 (29.73),59.91 (31.34), and 42.64 (28.00) in women respectively, which had a tendency to gradually decrease. The accumulative scores of CVHP and their distributions at the same age stage in all the 4 groups had significant differences (P ＜ 0.01 ). The accumulative scores of CVHP and their distributions for the same factors between all age groups also had significant differences (P ＜0. 01). Conclusions: The accumulative scores of CVHP had a tendency to gradually decrease from the health adults, risk factor exposure to high risk status before stroke. The decrease of the accumulative scores is closely associated with the increase of stroke risk, which can be used as a predictor of stroke.
