Objective:To investigate the CD163 expression characteristics in intracranial aneurysm (IA) tissue and blood of patients with IA and its feasibility as an early clinical screening indicator for IA.Methods:A total of 28 patients with IA admitted to Department of Neurosurgery, First Affiliated Hospital of Xinjiang Medical University from January 2021 to November 2023 were selected as IA group, and 28 healthy subjects from Health Management Center, First Affiliated Hospital of Xinjiang Medical University at the same time period were selected as control group. Eight saccular IA tissues and 12 superficial temporal artery tissues were collected from patients from IA group accepted IA clipping, and real-time fluorescent quantitative PCR (RT-qPCR) was used to detect the CD163 mRNA expression in these tissues. RT-qPCR was also used to detect the CD163 mRNA expression in the blood of the 2 groups. Seven patients with IA and 7 control subjects from the above 2 groups were randomly selected, respectively; and plasma CD163 protein content was detected by enzyme-linked immunosorbent assay (ELISA). Multivariate Logistic regression was used to analyze the influencing factors for IA. Receiver operating characteristic (ROC) curve was used to analyze the diagnostic values of blood CD163 mRNA expression and plasma CD163 protein content in IA. Results:CD163 mRNA expression in IA tissues was significantly higher than that in superficial temporal artery tissues (41.870±20.355 vs. 6.080±5.444, P<0.05). CD163 mRNA expression in the blood of IA patients was significantly higher than that in the controls (1.969[1.124, 2.318] vs. 1.124[0.933, 1.379], P<0.05). CD163 mRNA expression in the blood of ruptured IA group, unruptured IA group, and control group was gradually decreased, with significant differences ( P<0.05). CD163 mRNA expression in the blood of female IA patients was not statistically different compared with that in male IA patients ( P>0.05). ELISA showed that the CD163 protein content in plasma of the IA group was significantly higher than that in the control group [10.537±1.879] ng/L vs. [8.598±0.885] ng/L, P<0.05). Multivariate Logistic regression analysis showed that age and CD163 mRNA expression in the blood were independent influencing factors for IA occurrence ( OR=0.844, 95% CI: 0.750-0.951, P=0.005; OR=0.111, 95% CI: 0.024-0.506, P=0.004). ROC curve showed that the area under the curve (AUC) of CD163 mRNA expression in blood in diagnosing IA was 0.759 (95% CI: 0.618-0.890, P=0.002), and that of CD163 protein content in plasma in diagnosing IA was 0.864 (95% CI: 0.610-1.000, P=0.035). Conclusion:CD163 mRNA expressions in blood and IA tissues and CD163 protein content in plasma are high in patients with IA; CD163 mRNA expression in blood is an independent risk factor for IA; CD163 protein in plasma can be used as a molecular marker for screening IA.

Objective:To evaluate endoscopic retrograde appendicitis therapy in treatment of children with acute uncomplicated appendicitis.Methods:Sixty children patients were admitted at the Affiliated Hospital of Zhengzhou University from Oct 2019 to Jun 2021 and were divided into ERAT group ( n=30) and LA group ( n=30). Results:All operations were successfully performed . ERAT children started oral feeding earlier [(6.8±2.0) h vs. (12.3±2.0) h, t=-10.636, P<0.001], postoperative hospital stay was shorter [(3.2±1.3) d vs. (5.0±1.3) d, t=-5.360, P<0.001]. After 14 months follow up, the recurrence rate in the ERAT group was 6%. The complication rate of LA was 10%. Conclusion:ERAT is a safe and effective therapy in treating children with acute uncomplicated appendicitis with low,acceptable recurrence rate.

Objective: To investigate the clinical practicability and prognostic value of Helsinki CT score in patients with traumatic brain injury (TBI). Methods: A retrospective case series study was conducted to analyze the clinical data of 124 TBI patients admitted to First Affiliated Hospital of Xinjiang Medical University from September 2016 to October 2018. There were 91 males and 33 females, aged 14-84 years, with an average age of 49 years. Glasgow coma score (GCS) at admission ranged from 3-8 points in 45 patients, 9-12 points in 42 patients, and 13-15 points in 37 patients. According to Glasgow outcome scale (GOS) at 6 months after injury, 26 patients were classified into the poor prognosis group with GOS of 1-3 points and 98 patients were in the good prognosis group with GOS of 4-5 points. The prognosis-related risk factors were analyzed, and the role of Helsinki CT score to predict the adverse prognosis and mortality of TBI patients in the two groups was investigated. The sensitivity and specificity of Helsinki CT Score for 6-month poor prognosis were evaluated by receiver operation characteristic (ROC) curve and area under the curve (AUC). Results: Univariate analysis suggested that there were significant differences in terms of subdural hematoma, intracranial hematoma, extradural hematoma, hematoma volume >25 cm^3, intraventricular hemorrhage and suprasellar cistern pressure between the poor prognosis group and good prognosis group (P<0.05). Multivariate logistic regression analysis showed that the mortality and bad prognosis were related to the hemorrhage of ventricles, the pressure of suprasellar cistern and the disappearance of suprasellar cistern in the poor prognosis group and the good prognosis group (P<0.05), while intracranial hematoma and hematoma volume showed no association with mortality and poor prognosis (P>0.05). The Helsinki CT score could independently predict the adverse prognosis and mortality of TBI patients at 6 months (multivariate logistic regression: OR_death=1.21, OR_{adverse prognosis}=1.14). Helsinki CT score had a better predictive ability of 6-month mortality (AUC=0.85) than that of 6-month adverse prognosis (AUC=0.76), and had a predictive value for 6-month mortality and adverse prognosis. Conclusions Subdural hematoma, extradural hematoma, intraventricular hemorrhage and suprasellar cistern state (compression or disappearance) are the risk factors for the poor prognosis of TBI patients. Intraventricular hemorrhage and suprasellar cistern state are the main risk factors for predicting the mortality of 6 months. Helsinki CT score can independently predict the adverse prognosis and mortality of TBI patients at 6 months, and has relatively better value in predicting the mortality.

Objective: To summarize the experience of surgical treatment of 18 cases of severe aortic stenosis with ventricular septum hypertrophy. Methods: Clinical data of 18 patients with severe aortic stenosis admitted to the first affiliated hospital of zhengzhou university from January 2013 to December 2016 were collected. There were 7 males and 11 females. The mean age was (50.4±4.2) years old. All patients were diagnosed with severe stenosis of main artery valve by echocardiography before surgery, with mean aortic valve orifice area (0.57±0.11) cm^2, cardiac function (NYHA classification) grade Ⅱ in 4 patients, grade Ⅲ in 9 patients, and grade Ⅳ in 5 patients. There were 8 patients with mild aortic valve insufficiency, 4 patients with mild to moderate mitral valve insufficiency, 2 patients with moderate to severe aortic valve insufficiency, 3 patients with ascending aorta dilatation (ascending aorta inner diameter>4.5 cm), and 1 patient with atrial fibrillation. Interventricular septum thickness (15.82±2.04)mm, left ventricular posterior wall thickness (14.04±1.28)mm, ratio of interventricular septum thickness to left ventricular posterior wall thickness (IVS/LVPW) 1.12±0.91, inner diameter of left ventricular outflow tract (19.01±1.74)mm, cross-lobe differential pressure (102±8.40) mmHg (1 mmHg=0.133 kPa), left ventricular ejection fraction (LVEF) mean 0.49±0.05. Left ventricular end-diastolic diameter (LVEDD) (53.33±4.00) mm, left ventricular end-systolic diameter (LVESD) (27.11±1.99) mm, and left ventricular mass index (277.1±37.3) g/m². All patients underwent aortic valve replacement (AVR) and partial interventricular septum resection under general anesthesia and conventional extracorporeal circulation, 2 patients underwent mitral valve formation (artificial valve ring), 2 patients underwent ascending aorta formation, and 1 patient underwent ascending aorta wrapping. During the operation, the time of extracorporeal circulation, aortic occlusion, number of defibrillation during the operation, type of valve implantation and postoperative complications were recorded. Regular follow-up was conducted to analyze the changes of various indexes at different preoperative and postoperative time. Results: There was no death in the whole group. 2 patients were treated with temporary pacemakers. After drug treatment, sinus rhythm was restored on the 3rd and 6th day after surgery, and temporary pacemakers were removed. Echocardiography reexamination 1 week after the operation showed that all patients had a good artificial valve function and 2 patients had minor regurgitation of mitral valve. The difference in pressure across the valve, inner diameter of the left ventricular outflow tract, cardiac function classification, ventricular septum thickness, valve orifice area, and left ventricular mass index were significantly improved compared with the preoperative level (P<0.05). LVEF, LVEDD, and LVESD were compared with the preoperative level (P<0.05). After 6 months of follow-up, the difference in LVEF and LVEDD was statistically significant compared with the preoperative level (P<0.05). Conclusion Severe aortic stenosis combined with ventricular septum hypertrophy and partial ventricular septal muscle resection is a simple additional procedure in the AVR process, which does not increase the surgical risk and has a significant effect, and is conducive to postoperative left ventricular function recovery.

Objective To investigate the clinical therapeutic effect of citicoline sodium combined with Shenxiong glucose in the treatment of senile hypertensive cerebral infarction in the elders.Methods 80 elderly patients with senile hypertensive cerebral infarctiontreated in our hospital were selected and randomly divided into the single treatment group and the combination treatment group,40 cases in each group.Both groups received the routine treatment.The single treatment group additionally received Shenxiong glucose injection (100 ml/d),while patients in the combination treatment group additionally received Shenqiong glucose injection combined with citicoline sodium intravenous infusion therapy (0.5 g/d),both groups were treated for 2 weeks.The levels of serum inflammatory factors,the neurological deficit score,the cognitive function score were compared and analyzed before and after treatment between two groups.Results After systemic treatment,the blood pressure and blood lipid levels of two groups were significantly improved,but there was no significant difference between the two groups (P ＞ 0.05);The serum levels of interleukin (IL)-6,IL-8 and tumor necrosis factor-α (TNF-α) of the combination treatment group improved more significantly (P ≤0.05).After treatment,the oxidative stress indexes were significantly improved in the two groups (P ≤ 0.05).The content of malondialdehyde (MDA) was decreased,while the superoxide dismutase (SOD) activity and nitric oxide (NO) content were increased significantly (P ≤ 0.05);and the improvement degree in the combination treatment group was better than in the single treatment group (P ≤0.05).The degree of improvement in the Modified Edinburgh-Scandinavia Stroke Scale (MESSS) and Hasegawa Dementia Scale (HDS) scores of the combination treatment group was more significant than those in the single treatment group (P ≤ 0.05).The total effective rate of the combination treatment group was 92.5％,which was significantly higher than that of the single group (75.0％),with statistically significant difference (P ≤ 0.05).No obvious adverse reactions happened in two groups during treatment.Conclusions Combination of citicoline sodium and shenxiang glucose on the basis of routine treatment can significantly reduce oxidative stress and inflammation levels,promote the recovery of neurological and cognitive functions,and improve the clinical efficacy and safety.It is worth popularizing and applying in the clinical treatment of senile hypertensive cerebral infarction.

The efficacy of decompressive craniectomy (DC) in reducing traumatic brain injury mortality has been affirmed,but there are also many serious complications.Syndrome of the trephined (ST) and paradoxical herniation (PH) are rare complications.ST is characterized by a series of neurological deterioration due to skin flaps subsidence from weeks to months after DC.These neurological impairments are closely related to the subsequent repair of skull defects.PH shows progressive decrease in consciousness on the basis of ST,changes in pupils on the side of skull defects,low touch pressure at the defect window,and obvious midline shift and brain stem compression on CT.ST and PH have common inducements in pathophysiology,including cerebrospinal fluid dynamics,atmospheric pressure,cerebral blood flow and brain material metabolism.There is no consensus on the diagnosis of ST and PH,and early cranioplasty is suggested in terms of treatment.This article reviews the clinical manifestations,pathophysiological changes,diagnosis and treatment of ST and PH after DC operation,so as to provide references for clinicians to further understand ST and PH.

Objective To explore the gender differences in the association between iron metabolism and bone turnover markers in elderly patients with fragility fracture.Methods A total of 271 patients admitted in our hospital from Aug 2014 to Oct 2017 with osteoporotic fractures were divided into two groups:109 males and 162 females,aged from 60 to 92 years.Both groups were further divided into 3 age groups(60 to 70,71 to 80,and ≥81 year group).Biochemical indicators,serum ferritin and bone turnover markers were detected eight hours after admission.Results In the male group,there were no statistical differences in serum ferritin and serum procollagen type Ⅰ Nterminal propeptide(PINP) among age groups (all P ＞ 0.05).Serum β-carboxy terminal telopeptide of collagen type Ⅰβ-CTX(β-CTX)was elevated with ageing.In the female group,serum ferritin,PINP,and β-CTX were elevated with ageing.There was a significant positive correlation between serum ferritin and β-CTX in two gender groups (all P ＜ 0.05)without gender difference.Gender difference was observed in the correlation between serum ferritin and PINP between two gender groups:a significant positive correlation in the female group (r =0.255,P =0.001)whereas a significant negative correlation in the male group(r=-0.207,P=0.031).Conclusions There are gender differences in correlations of serum ferritin with bone turnover markers.Increased iron accumulation in postmenopausal women is closely correlated with high bone turnover rate.

Objective To investigate the clinical efficacy of intracranial pressure monitoring in ventricular puncture for patients with posttraumatic diffuse brain swelling under guidance of real-time intraoperative ultrasound. Methods Sixty-seven patients with posttraumatic diffuse brain swelling, admitted to and accepted intracranial pressure monitoring in ventricular puncture under real-time intraoperative ultrasound in our hospital from January 2015 to December 2017, were chosen as experimental group; and other 71 patients with posttraumatic diffuse brain swelling, admitted to and accepted traditional intracranial pressure monitoring in ventricular puncture in our hospital from January 2012 to June 2014, were chosen as control group. The clinical data were retrospectively analyzed, and the success rate of primary puncture and complications were compared between the two groups. Results The success rate of primary puncture in the experimental group was 100％ (67/67), and that in the control group was 77.5％ (55/71), with significant difference (P<0.05). No catheter-related infection was noted in either group. Only one patient in study group had puncture tract bleeding, while 9 patients in the control group had puncture tract bleeding; abnormal puncture location was noted in 8 patients of the control group, including 5 failing to be punctured in the ventricle, one puncturing to the contralateral ventricle, and two having excessive puncture depth; occurrence of postoperative complications in study group was significantly lower than that in control group (P<0.05). Conclusion Real-time intraoperative ultrasound-guided puncture ventricle drainage is superior to conventional bind-puncture in traumatic patients with diffuse brain swelling, and can be widely used in clinical practice.

BACKGROUND: In animal experiments, ultrasound-mediated microbubbles can promote the homing of transplanted stem cells to the ischemic area, enhance angiogenesis and small arterial formation, improve local blood flow in the ischemic myocardium and restore myocardial contractility.OBJECTIVE: To investigate the effect of ultrasound-mediated microbubbles on intravenously transplanted bone marrow mesenchymal stem cell (BMSC) homing and the therapeutic efficiency on ischemic stroke. METHODS: A middle cerebral artery occlusion (MCAO) model was induced by plug wire preparation. At 72 hours after MCAO, model rats were randomized into four groups: PBS group (n=15), BMSCs group (n=18), ultrasound+BMSCs group (n=18), ultrasound+microbubble+BMSCs group (n=18). Corresponding treatment was done in each group: 2 mL of PBS was injected via tail vein in the PBS group; about 3×106 BMSCs diluted by 2 mL of PBS were injected via tail vein slowly in the BMSCs group; after skull ultrasound radiation (1 MHz, 2 W/cm2) for 120 seconds, BMSCs were injected via tail vein slowly in the ultrasound+BMSCs group; the same process as the ultrasound+BMSCs group was done following intravenous injection of 0.1 mL/kg microbubbles in the ultrasound+microbubble+BMSCs group.RESULTS AND CONCLUSION: (1) Forty-eight hours after BMSCs transplantation, the BMSCs homing rate in the brain was significantly higher in the ultrasound+microbubble+BMSCs group than the other two groups (P < 0.05). (2) Twenty-eight days after MCAO, nerve damage was significantly milder in the ultrasound+microbubble+BMSCs group than the other two groups (P < 0.05). (3) Seven days after transplantation, the water content in the brain tissue was significantly lower in the ultrasound+microbubble+BMSCs group than the other two groups (P < 0.05). (4) Seven days after transplantation, the cerebral infarction volume was significantly reduced in the ultrasound+microbubble+BMSCs group compared with the other two groups (P < 0.05). To conclude, ultrasound-mediated microbubbles can enhance the homing effect of intravenously transplanted BMSCs, reduce cerebral edema and cerebral infarction volume, improve the neurological function, and increase the therapeutic effect of BMSCs transplantation on ischemic stroke.

Objective To evaluate the association between bradycardia and neurological sequel in patients with restoration of spontaneous circulation (ROSC) after cardiopulmonary resuscitation (CPR) during targeted body temperature management (TTM).Methods Forty-three unconscious patients with ROSC after CPR were treated with TTP.The patients were cooled with therapeutic hypothermia to body temperature target range (32-34°C) after cardiac arrest and divided into bradycardia and control groups depending on the lowest heart rate less than 50 beats/min and more than or equal to 50 beats/min respcetively at that time.The bispectral index (BIS) and the neuron-specific enolase (NSE) values were respectively recorded at the following intervals,0h (h0)、24h (h24)、48h (h48)、72h (h72) after ICU admission.Neurological outcome was defined according to the Pittsburgh cerebral performance category (CPC) at 3 months after ICU discharge.Results Compared with the control group,during TTM the bispectral index levels were significantly higher in the bradycardia group at h0,h48,h72 after admission,(h0 bradycardia group 73.0 ± 12.3;control group 58.0 ± 18.6,P ＜0.01)、(h48 bradycardia group 71.4 ± 21.2;control group 46.3 ± 18.9,P ＜ 0.01)、(h72 bradycardia group 78.6 ± 24.6;control group 51.8 ± 24.1,P =0.01).The neuron-specific enolase level in bradycardia group was significantly lower than that in control group on day3 (118.8 ± 118.8 ng/mL vs.248.3 ± 191.9 ng/mL,P =0.02).The level of CPC in the bradycardia group was significantly higher than that in the control group (P =0.046).Conclusions Patients with bradycardia during TTM had favorable neurological outcome,which could provide evidence for clinical treatment and prognostic evaluation of the patients.
