Objective To investigate the accuracy and application value of the Tada formula in evalua-ting the meningioma volume based on 3D reconstruction technology.Methods The thin-slice magnetic reso-nance images of 297 patients with meningioma treated in the neurosurgery department of 940 Hospital of PLA Joint logistics Support Force from January 2014 to May 2022 were retrospectively analyzed.The meningioma volume was evaluated by the Tada formula method and three-dimensional reconstruction method respectively.The accuracy of the evaluation of meningeal tumor volume by the Tada formula was analyzed by grouping sta-tistics.Results In the whole sample and the concentrated sample,the obtained meningioma total volumes had no statistical difference between the two methods(P＞0.05),the Spearman correlation coefficients were 0.995 and 0.993 respectively,and the intragroup correlation coefficients(ICC)were 0.992 and 0.989,respec-tively.In the Bland-Altman plot,most of the data points were within the limit of uniformity.Compared with different groups,the Tada formula had a slightly lower accuracy in the volume assessment of meningiomas with higher degree of irregularity,and a better accuracy in the volume assessment of supratentorial meningio-mas than subtentorial meningiomas.Conclusion The Tada formula could accurately evaluate the volume of meningioma,and it could be used as a preliminary method to evaluate meningioma volume in clinic

Objective:To evaluate the reliability and validity of the Chinese version of HEMO-FISS-QoL(HF-QoL) questionnaire (HF-QoL-C) in the Chinese population with hemorrhoids.Methods:From November 2021 to November 2022, a self-constructed general information questionnaire, HF-QoL-C, and the 36-item short form health survey (SF-36), Goligher classification, and Giordano severity of hemorrhoid symptom questionnaire (GSQ) were used to conduct a questionnaire survey on 760 hemorrhoid patients in the anorectal department of six hospitals. The data was analyzed for reliability and validity using SPSS 21.0 and AMOS 26.0 software.Results:The Cronbach's α coefficient of HF-QoL-C and its dimension ranged from 0.831 to 0.960, and the split coefficient was 0.832-0.915. Four common factors were extracted through principal component exploratory factor analysis. Confirmatory factor analysis indicated acceptable structural validity( χ2/ df=8.152, RSMEA=0.097, CFI=0.881, IFI=0.881, NFI=0.867). HF-QoL-C was correlated with SF36 and GSQ( r=-0.694, 0.501, both P<0.01). There were differences in the total score and dimensional scores of HF-QoL-C between surgical and drug treated patients, different grades of Goligher classification for hemorrhoidal disease, and different ranges of hemorrhoid prolapse (all P<0.001). No ceiling effect was found in the total score and the scores of each dimension(0.3%-2.0%). There was a floor effect in both psychological function and sexual activity dimensions (16.7%, 35.1%). Conclusion:HF-QoL-C has good reliability and validity, which can be used to measure the quality of life of Chinese hemorrhoid patients.

Objective To analyze the correlation between serum 25-hydroxyvitamin D[25(OH)D]and inflammatory cytokines such as interferon γ(IFN-γ),C-reactive protein(CRP)and interleukin-2(IL-2)in neonatal pneumonia.Methods A total of 100 neonates admitted to First Hospital of Qinhuangdao from December 2018 to December 2020 were enrolled in this study.According to the serum 25(OH)D level,they were divided into deficiency group(≤15.0 μg/L,n=18),inadequate group(15.1-20 μg/L,n=42),and adequate group(＞20.0 μg/L,n=40).The general and clinical data such as gender,gestational age,serum 25(OH)D level,birth weight,mode of delivery and the levels of IFN-γ,CRP and IL-2 were compared among the three groups.The correlation between vitamin D deficiency and levels of IFN-γ,CRP and IL-2 was analyzed.Results There were no significant differences in gestational age,sex,birth weight,or delivery mode among the three groups(P＞0.05).Serum 25(OH)D levels in the three groups were as follows:deficiency group＜inadequate group＜adequate group,and there were significant differences in the serum 25(OH)D level between groups(P＜0.05).The levels of IFN-γ,CRP and IL-2 in the deficiency group were higher than those in the inadequate group and adequate group(P＜0.05),and the levels of IFN-γ,CRP and IL-2 in the inadequate group were higher than those in the adequate group(P＜0.05).The Pearson correlation analysis showed that serum 25(OH)D level was negatively correlated with IFN-γ,CRP and IL-2 levels in newborns(P＜0.05).Conclusion The lower the serum 25(OH)D in newborns,the more deficient the vitamin D and the higher the levels of IFN-γ,CRP and IL-2 are,indicating higher risk of pneumonia.

Objective:To introduce the early results of total aortic arch replacement (TAA) without cardiopulmonary bypass (CPB) and without interruption of cerebral blood supply, using the technique of arch branches preferential reconstruction and whole brain perfusion for brain protection.Methods:Between June 2020 and March 2021, a total of 9 Stanford type A aortic dissection patients we performed total arch replacement by using the technique of arch branches preferential reconstruction and whole brain perfusion without cardiopulmonary bypass and without interruption of blood supply to the brain. The method of this reconstruction technique is as follows: A 24F aortic cannula was inserted into the true lumen at the root of the transverse innominate artery (IA) to connect one end of the artery for cardiopulmonary bypass. The access was connected to 14F artery via Y-connector and inserted into IA cavity to maintain blood supply to brain. Without cardiopulmonary bypass, the 10 mm branch of the four branch artificial blood vessel was anastomosed with the innominate artery IA. The perfusion collateral was connected to the second end of the artery of CPB (single pump and double tubes) to continue to supply blood for IA. The left common carotid artery (LCA) and left subclavian artery (LSCA) were reconstructed by the same method. When IA and LCA were anastomosed, the distal blood supply was not interrupted. After the three branches of the aortic arch were anastomosed, we started to turn the machine, then cooled down and blocked the ascending aorta to further complete the operation of the aortic root and arch. During the period of lower body circulatory arrest, the whole brain was perfused with low flow.Results:No intraoperative death or perioperative complications occurred in all patients, and they were discharged smoothly. The cardiopulmonary bypass time was (192.4±58.1) min, the aortic clamping time was (128.3±52.4) min, the lower body circulatory arrest time was (29.1±1.3) min, and the postoperative awake time was (8.2±3.7) h.Conclusion:Off-pump arch branches preferential reconstruction can provide physiological whole brain perfusion, shorten the cardiopulmonary bypass time and aortic occlusion time, and the operation is safe and effective.

Objective To investigate the effect of Santong electroacupuncture (EA) on mRNA and protein expression of p75 neurotroph-in receptor (p75NTR) in rats with spinal cord injury (SCI). Methods A total of 72 female Sprague-Dawley rats were randomly assigned to sham operation group (group A, n=8) and model group (n=64). In the model group, Allen's method was used to make SCI rats model, in which 48 survived model rats were further subdivided into model control group (group B, n=12), EA group (group C, n=12), inhibitor Nogo extra cellular peptide residues 1-40 (NEP1-40) group (group D, n=12) and EA+inhibitor NEP1-40 group (group E, n=12) according to de-sign proposal. The treatment groups were electroacupunctured on Dazhui (GV14) and Yaoyangguan (GV3), bilateral Ciliao (BL32) and Zu-sanli (ST36) with loose-tight wave, for 20 minutes every day. After 7 and 14 days of treatment, injured spinal cord tissue was extracted for detecting. The mRNA and protein expression of p75NTR was detected by real-time fluorescent quantitative PCR, in situ hybridization and Western blotting respectively. The hind limb motor function was assessed with Basso-Beattie-Bresnahan (BBB) score. Results The BBB score increased in the treatment groups compared with group B, and was higher in group E than in groups C and D (P<0.05), as well as on the 14th day than on the 7th day in all the treatment groups (t>2.623, P<0.05). The mRNA and protein expression of p75NTR in spinal cord tissues decreased in the treatment groups compared with group B (P<0.05), and no significant difference was found among the treatment groups (P>0.05). Conclusion Santong elerctroacupuncture treatment could improve the hind limb motor function, which may associate with inhibition of the mRNA and protein expression of p75NTR in rats after SCI.

Objective To investigate the efficacy of Atorvastatin in reducing the recurrence rate of chronic subdural hematoma (CSDH) after single burr hole drainage and irrigation.Methods Between January 2000 and May 2005 and between January 2013 and December 2015,122 patients with CSDH admitted to the Neurosurgery Department,Lanzhou General Hospital were treated with single burr hole drainage and irrigation under local anesthesia.All patients were classified into two groups.Patients in the treatment group (n=67) took Atorvastatin after operation and those in the control group (n=55) did not take Atorvastatin.Patient demographics,clinical characteristics,imaging data,Markwalder's Grading Scale (MGS) and recurrence rates were assessed.Results Preoperative clinical characteristics and MGS levels at discharge were similar between the two groups (all P＞0.05).The recovery rate of CSDH was 98.5％ in the treatment group,without recurrence or death.The recovery rate of CSDH was 96.4％ in the control group,with four cases of relapse,making up a recurrence rate of 7.3 ％ (4/55).As a result,the recurrence rates were statistically significantly different between the two groups (x2 =5.038,P =0.039).Conclusions Atorvastatin can significantly reduce the recurrence rate of CSDH after single burr hole drainage and irrigation.

OBJECTIVETo investigate the role of left atrial appendage (LAA) closure for cerebral ischemic stroke prevention following mitral valve replacement.

METHODSRetrospective data on 860 consecutive adult patients undergoing mitral valve replacement between January 2008 and January 2013 were analyzed. There were 414 male and 446 female patients, with a mean age of (53 ± 12) years. The patients were divided into two groups according to whether the left atrial appendage was closed during operation: LAA closure group (n = 521) and non-LAA closure group (n = 339).Early mortality, postoperative cerebral ischemic stroke and the risk factors for cerebral ischemic stroke were assessed. Multivariate analysis was performed using logistic regression analysis.

RESULTSCompared with non-LAA closure group, LAA closure group had higher proportion of female gender, higher percentage of patients with cardiac insufficiency, pulmonary hypertension and left atrial thrombus, higher incidence of mechanical valve implantation and concurrent tricuspid surgery, and larger preoperative diameter of left atrium, but lower proportion of hypertension and patients undergoing coronary artery bypass surgery, and shorter aorta cross clamping time (χ² = 6.807 to 122.576, t = -2.818 and 3.756, all P < 0.05). There were no differences in exploratory thoracotomy for bleeding and in-hospital mortality between the two groups. Postoperative cerebral ischemic stroke occurred in 12 patients (1.4%). The incidence of cerebral ischemic stroke in LAA closure group was significantly lower than in non-LAA closure group (0.6% vs.2.7%, χ² = 6.452, P = 0.011).Logistic regression analysis showed that LAA closure was a significant protective factor for postoperative cerebral ischemic stroke (OR = 0.189, 95% CI: 0.039 to 0.902, P = 0.037) while history of cerebrovascular disease (OR = 4.326, 95% CI:1.074 to 17.418, P = 0.039) and preoperative diameter of left atrium (OR = 1.509, 95% CI: 1.022 to 1.098, P = 0.002) being the independent risk factors for postoperative cerebral ischemic stroke. The subgroup analysis showed that, for atrial fibrillation patients, LAA closure was a strong protective factor (OR = 0.064, 95% CI: 0.006 to 0.705, P = 0.025), but LAA closure was not a significant predictive factor (OR = 1.902, 95% CI: 0.171 to 21.191, P = 0.601) in non-atrial fibrillation patients.

CONCLUSIONConcurrent LAA closure during mitral valve replacement is safe and effective to reduce the early postoperative risk of cerebral ischemic stroke in atrial fibrillation patients.

OBJECTIVETo analysis the influence of surgical revascularization on different timing after ST-elevation myocardial infarction (STEMI) on patients with coronary artery disease and left ventricular dysfunction.

METHODSClinical data of 225 patients admitted from January 2003 to July 2012 with history of STEMI and left ventricular dysfunction (ejection faraction<50%) who underwent isolated coronary artery bypass grafting was retrospectively reviewed. There were 186 male and 39 female patients. According to the timing of surgical revascularization after STEMI, the patients were divided into early revascularization group (ER group, <21 days), mid-term revascularization group (MR group, 21 to 90 days) and late revascularization group (LR group, >90 days). There were 20 male and 9 female patients in ER group with mean age of (63 ± 10) years, 48 male and 16 female in MR group with mean age of (63 ± 8) years, 118 male and 14 female in LR group with mean age of (62 ± 10) years, respectively. Thirty-day post-operative mortality and major complications were determined as the endpoints to evaluate the early results of operation.

RESULTSThe 30-day post-operative mortality were 3.4%,0 and 2.3% among three groups respectively and there was no statistic difference between groups (χ(2) = 2.137, P = 0.330).Low cardiac output syndrome mortality were 13.8%, 3.1% and 2.3% among three groups respectively and there was statistic difference between groups (χ(2) = 8.344, P = 0.015). The ejection fractions was significantly improved in all the three groups from 42% ± 6%, 41% ± 6% and 42% ± 6% preoperatively to 46% ± 7%, 45% ± 10% and 45% ± 9% postoperatively (t = -3.378 to -2.339, all P < 0.05). The left ventricular end diastolic dimension were significantly reduced in MR group and LR group from (54 ± 6) mm and (55 ± 6) mm preoperatively to (47 ± 8) mm and (49 ± 9) mm postoperatively (t = 5.634, 5.885; P = 0.000). There was no significant change in ER group pre- and postoperatively ((51 ± 6) mm vs.(49 ± 7) mm, t = 1.524, P = 0.133).

CONCLUSIONSThe patients with coronary artery disease and left ventricular dysfunction can benefit from surgical revascularization on different timing after STEMI, presenting as the reverse of left ventricle remodeling and the improvement of left ventricle function. The short-term results are mainly determined by the patients' condition, surgical technique and the level of perioperative management.It is recommended for this patient cohort to accept surgical revascularization three weeks after STEMI.
