Objective To explore the role of serum leucine-rich-alpha-2-glycoprotein1(LRG1),neopterin(NPT)and virus antibodies during the progression of viral meningitis(VM)and their value in evaluating the condition and predicting the prognosis of VM in children.Methods A total of 130 pediatric patients with VM admitted to Kaifeng Children's Hospital from August 2020 to February 2023 were selected as the observation group,and at the same time,another 130 pediatric patients with VM symptoms who were diagnosed as non central nervous system infectious diseases by lumbar puncture cerebrospinal fluid examination were selected as the control group.After admission,2 mL peripheral venous blood of children in the two groups was collected,and the levels of serum LRG1 and NPT were assessed by enzyme-linked immunosorbent assay.Before treatment,1 mL cerebrospinal fluid sample of children in the two groups was collected by lumbar puncture,and the host specific immuno-globulin G(IgG)against herpes simplex virus-I(HSV-I),cytomegalovirus(CMV),Epstein-Barr virus(EBV),and parain-fluenza virus(PIV)in cerebrospinal fluid was detected by enzyme-linked immunosorbent assay.The levels of serum LRG1 and NPT,as well as the positive rate of virus antibody IgG were compared between the two groups.The VM children were then divided into the severe group(n=54)and mild group(n=76)according to the disease severity,and they were divided into the good prognosis group(n=37)and poor prognosis group(n=93)based on the prognosis.The levels of serum IRG1 and NPT and the positive rate of virus antibody IgG were compared in children with different disease severity and prognosis.The correlation of serum LRG1,NPT and virus antibody with the disease severity or disease progression for pediatric VM was analyzed,and their interactive effects on the disease progression of children with VM were analyzed.The predictive value of serum LRG1,NPT and virus antibody for pediatric VM outcome was analyzed by the receiver operating characteristic(ROC)curve.Results The levels of serum LRG1 and NPT,as well as the positive rate of virus antibody IgG of children in the obser-vation group were significantly higher than those in the control group(P＜0.05);the levels of serum LRG1 and NPT,as well as the positive rate of virus antibody IgG of children in the severe group were significantly higher than those in the mild group(P＜0.05);the levels of serum LRG1 and NPT,as well as the positive rate of virus antibody IgG of children in the poor prognosis group were significantly higher than those in the good prognosis group(P＜0.05).High level of serum LRG1 with high positive rate of virus antibody IgG and high level of serum NPT with high positive rate of virus antibody IgG showed positive interactions in leading to poor prognosis in children with VM odds ratio(OR)=15.238,9.684).The submultiplicative models were applied for the high levels of serum LRG1 with high positive rate of virus antibody IgG(OR=15.238)and high levels of serum NPT with high positive rate of virus antibody IgG(OR=9.684).The area under the curve(AUC)for predicting poor prognosis in children with VM after 2 weeks of treatment by serum LRG1,NPT and virus antibody IgG were 0.786,0.794 and 0.919,respectively,and the AUC for the combined prediction of the three was 0.933;the AUC of LRG1,NPT and positive rate of virus antibody IgG for predicting poor prognosis in children with VM after 2 weeks of treatment was greater than that of the three alone(P＜0.05).Conclusion NPT and LRG1 may be involved in the development of VM.The levels of serum LRG1 and NPT are positively correlated with the severity and progression of VM.The levels of serum NPT and LRG1 and the positive rate of virus antibody IgG have certain value in the disease evaluation and prognosis prediction of VM,and the combination of the three has a higher predictive value for the prognosis of VM.There is a positive interaction between high LRG1 with high positive rate of virus antibody IgG,and high NPT with high positive rate of virus antibody IgG in children with VM.

Objective:To analyze the safety and efficacy of endovascular treatment in fusiform aneurysms at V4 segment of vertebral artery.Methods:Twenty-five patients with fusiform aneurysms at V4 segment of vertebral artery, accepted endovascular treatment in Department of Cerebrovascular Diseases, Second Affiliated Hospital of Kunming Medical University from May 2016 to January 2022 were chosen; their clinical data were retrospectively analyzed. The short-term (within one month of surgery) and long-term (>8 months of surgery) complications were evaluated, including aneurysm re-bleeding and ischemic stroke. All patients were followed up for 3-21 months; aneurysm recurrence and parent arteries were evaluated by DSA. The prognosis of patients was evaluated by modified Rankin scale (mRS) at the last follow-up (mRS scores of 0-2 as good prognosis).Results:Twenty-six aneurysms involved in 25 patients, including 13 ruptured aneurysms and 13 un-ruptured aneurysms; 7 aneurysms were located at the dominant vertebral artery and 7 aneurysms involved in the origin of posterior inferior cerebellar artery (PICA). In these 13 ruptured aneurysms, 6 (46.15%) were treated with parent artery sacrifice and 7 (53.85%) were with stent-assisted coil embolization; in 13 un-ruptured aneurysms, 9 (69.23%) were treated with stent-assisted coil embolization and 4 (30.77%) were with flow diversion devices (Tubridge). Seven aneurysms (43.75%) used multi-stent in these 16 aneurysms accepted stent-assisted coil embolization. No short-term and long-term re-bleeding or ischemic stroke were noted in all patients. Twenty patients completed DSA follow-up, with a median follow-up time of 8 months; 3 patients had recurrent aneurysms and one had asymptomatic stent occlusion. All 25 patients completed the last follow-up (telephone or outpatient follow-up) in May 2022, and 24 had good prognosis.Conclusion:According to characteristics of dominant vertebral artery and relations between aneurysms and PICA, individualized endovascular treatment can be safe and effective in fusiform aneurysms at V4 segment of vertebral artery.

Objective:To evaluate the safety and efficacy of bipolar plasmakinetic endoscopic enucleation of the prostate (BEEP) in the treatment of benign prostatic hyperplasia (BPH) in a day surgery mode.Methods:The clinical data of 162 BPH patients admitted to the First Affiliated Hospital of Anhui Medical University from January 2021 to June 2022 were analyzed retrospectively. The patients were divided into day group(80 cases) and conventional group(82 cases) according to hospitalization mode. In the day group, preoperative screening and anesthesia evaluation was completed during the pre-hospitalization period, and the patient was discharged within 24 hours. The two groups were treated with BEEP, the urethral mucosa was cut at a " Ω" 5 mm proximal to the external sphincter ring in front of the verumontanum. Following the standard of anatomical enucleation of the prostate, the gland tissue was cut out after enucleation. There were no significant differences in age [(63.6±8.9) years vs. (67.5±7.1) years], body mass index [(24.3 ±2.6) kg/m 2vs. (23.0±3.2) kg/m 2], prostate volume [(55.8±16.9) ml vs. (53.7±20.7) ml], preoperative prostate-specific antigen [3.8(1.2, 5.3)ng/ml vs. 3.5(2.1, 5.6)ng/ml], the international prostate symptom score (IPSS) [(25.9±5.2) vs. (26.3±5.9)], the quality of life score (QOL) [(5.0±0.7) vs.(5.0±0.6)], the maximum urine flow rate (Q max) [(8.2±4.5) ml/s vs. (7.9±4.1) ml/s] and residual urine volume (PVR) [49(0, 131) ml vs. 45(11, 106) ml] between the two groups ( P>0.05). The waiting time before admission was [(2.6±1.2) d vs. (5.3±1.5) d], and the difference between the two groups was statistically significant ( P<0.05). The perioperative efficacy indicators, total hospitalization expenses and short-term postoperative complications were compared between the two groups. Results:In this study, all patients successfully completed the operation. There were no statistical significances in the perioperative indicators between the day group and the conventional group including the operation time [(38.4±15.2) min vs. (40.4±13.9) min], enucleated tissue weight [(34.6±9.6) g vs. (35.4±10.8) g], the decrease value of hemoglobin [(13.0±2.5) g/L vs. (12.0±3.7) g/L] and the decrease value of blood sodium [(2.2±0.9) mmol/L vs. (2.4±1.3) mmol/L]( P>0.05). The significant differences were observed in bladder irrigation time [(16.9±2.1)h vs. (22.7±12.1)h], catheterization time [(18.8±5.1) h vs.(65.6±13.0)h], postoperative hospital stay [(16.8±2.4)h vs. (64.8±6.3)h] and the total hospitalization expenses [(13 282.2±2 236.3) yuan vs. (15 969.3±2 420.6) yuan] between the day group and the conventional group ( P < 0.01). In the day group, 1 case was transferred to the general ward for observation for 1 day. There were no significant differences in the incidence of complications as urinary retention [6.3% (5/80) vs. 3.7% (3/82)], temporary incontinence [2.5% (2/80) vs. 2.4%(2/82)], urethra stricture [7.5% (6/80) vs. 6.1% (5/82)], and hematuria for intervention [1.3% (1/80) vs. 1.2% (1/82)]between the day group and the conventional group ( P > 0.05). After 6 months of follow-up, there were no significant differences in IPSS[(6.7±2.8) vs. (6.1±2.5)], QOL[(1.8±0.9) vs. (2.0±0.8)], Q max [(26.4±5.5)ml/s vs. (25.8±4.6)ml/s] and PVR [7(2, 11)ml vs. 5(4, 8)ml] between the two groups at 6 months after operation ( P > 0.05), but there were significant improvements when compared with those items of preoperation ( P < 0.01). Conclusions:The treatment of BPH with BEEP in the day surgery mode is as safe and effective as that in the conventional surgery mode, with little bleeding, high resection efficiency, definite therapeutic effect and low incidence of complications. BEEP can shorten the length of hospital stay and reduce medical expenses in the day surgery mode, and can be carried out in hospitals with conditions.

Autologous ozonized blood transfusion(AOBT) is a therapy of re-transfusion of 100-200 mL of autologous blood after shaking and agitation with appropriate amount of oxygen-ozone in vitro. The oxidation of blood through the strong oxidation of ozone can enhance the non-specific immune response of the body, regulate the internal environment and promote health. This therapy has been increasingly applied in clinical practice, while no unified standard for the operation process in terms of ozone concentration, treatment frequency and treatment course had been established. This operation process of AOBT is primarily explored in order to standardize the operation process and ensure its safety and efficacy.

Objective To study the effects of aneurysmal neck angle on stent displacement after endovascular repair of abdominal aortic aneurysm (AAA). Methods The CT images of 28 patients were selected to establish preoperative AAA model, postoperative AAA model and covered stent model respectively, and the models were divided into non-severe angulation group ( n = 14) and severe angulation group ( n = 14) according to the preoperative angle of tumor neck. The geometric shape of each model was measured, and the changes of AAA geometric parameters and postoperative stent displacements before and after surgery were analyzed. The displacement force of the model during the first follow-up was calculated by hemodynamic simulation. Results Significant differences were found in tumor length, maximum diameter, displacement force, tumor neck length and tumor volume between two groups of patients (P<0. 05), while there was no significant difference between COG (the center of gravity) displacement and proximal displacement (P> 0. 05). For the incidence of internal leakage, there were 2 cases in non-severe angulation group and 4 cases in severe angulation group (P>0. 05).Conclusions Severe neck angulation can lead to a significant increase in support displacement force and decrease in proximal anchorage zone, and thus increase the possibility of support displacement. It is suggested that doctors should strengthen postoperative follow-up for patients with severe neck angulation and be vigilant of the occurrence of long-term internal leakage in clinic.

OBJECTIVES: To evaluate the feasibility and safety of bipolar-plasmakinetic transurethral enucleation and resection of the prostate (B-TUERP) in day surgery. METHODS: From January 2021 to August 2022, 34 patients with benign prostatic hyperplasia (BPH) underwent B-TUERP in day surgery in the First Affiliated Hospital of Anhui Medical University. Patients completed the screening and anesthesia evaluation before admission and received the standard surgery which implements "anatomical enucleation of the prostate" and "absolute bleeding control" on the same day of admission, and by the same doctor. Bladder irrigation was stopped, catheter was removed and the discharge evaluation was performed on the first day after operation. The baseline data, perioperative conditions, time of recovery, treatment outcomes, hospitalization costs, and postoperative complications were analyzed. RESULTS: All operations were successfully conducted. The average age of the patients was (62.2±7.8) years, average prostate volume was (50.2±29.3) mL. The average operation time was (36.5±19.1) min, the average hemoglobin and blood sodium were decreased by (16.2±7.1) g/L and (2.2±2.0) mmol/L, respectively. The average postoperative length of hospital stay, and total length of hospital stay were (17.7±2.2) and (20.8±2.1) h, respectively, and the average hospitalization cost was (13 558±2320) CNY. All patients were discharged on the day after surgery except for one patient who was transferred to a general ward. Three patients received indwelling catheterization after catheter removal. The 3-month follow-up results showed a substantial improvement in the International Prostate Symptom Score, quality of life score and maximum urinary flow rate (all P<0.01). Three patients experienced temporary urinary incontinence, 1 patient experienced urinary tract infection, 4 patients were diagnosed with urethral stricture and 2 patients experienced bladder neck contracture. No complications above Clavien grade Ⅱ occurred. CONCLUSIONS The preliminary results showed that B-TUERP ambulatory surgery is a safe, feasible, economical and effective treatment for appropriately selected patients with BPH.

Osteoarthritis (OA), a chronic joint degenerative disease, is the significant cause of the loss of joint function in middle-aged and older people. Bone destruction, synovial hyperplasia, osteophyte formation, and subchondral bone sclerosis are the main features of osteoarthritis, and the typical symptom is severe joint pain. Consequent to unprecedented global population aging, osteoarthritis remains a leading cause of disability, and the treatment often comes at a high cost. With an in-depth understanding of related research, osteoarthritis is proven to be a multifactorial disease whose onset is not simply a cartilage lesion, and the immune plays an essential role in the development of the disease. Some studies proposed that chondrocytes are capable of altering gene expression and mediating osteoarthritis progression by regulating immune responses. Previous studies showed that the extent of immune dysregulation significantly correlates with the severity of osteoarthritis, revealing an association between immunity response and clinical manifestations. The study of immune infiltration, genetic alterations, and pathogenesis of osteoarthritis may provide new perspectives and methods for the treatment of osteoarthritis in the future. Therefore, this review, combined with the recent decade of literature, provides an overview of the research progress of the main immune cells and related cytokines in OA, which may provide a new direction of thinking for diagnosing and preventing this disease.

Objective: To study the effect of low-to-moderate dose glucocorticoid therapy on viral clearance time in patients with COVID-19. Methods: A total of 72 patients diagnosed with COVID-19 from January 19 to February 17, 2020 at the First Affiliated Hospital, School of Medicine, Zhejiang University were recruited. All patients received oral abidol and/or combined lopinavir/ritonavir, darunavir antiviral, and symptomatic supportive care. Among them, 51 patients received methylprednisolone (0.75-1.50 mg·kg^-1·d^-1) (glucocorticoid treatment group), and 21 patients who did not use glucocorticoid were the control group. The time of stable virologic conversion insputumand the time of radiologic recovery in lungsince onset were compared between the two groups and among the normal patients.The Kruskal-Wallis test or Fisher exact test was used to compare the difference between groups. Results: The median ages of the glucocorticoid group and the control group were 52 [interquartile range (IQR):45, 62] years and 46 (IQR: 32, 56)years, and the differences were significant (P<0.05). The clinical conditions at hospital admission were different between the two groups (P<0.01). There were 52.0% critical ill patients in the glucocorticoid treatment group, compared to that of 71.4% normal patients in the control group. The median times from the onset tostable virologic conversion to negative in the two groups were 15 (IQR:13,20) days and 14 (IQR:12,20) days (P>0.05), and the difference was no statistically significant. The median times from onset to radiologic recovery were 13 (IQR: 11,15) days and 13 (IQR:12,17) days in the two groups, and there was no difference (P>0.05). In ordinary patients, the median timesfrom the onset tostable virologic conversion insputum were no difference (P>0.05), with 13 (IQR:11,18) days in the glucocorticoid group and 13 (IQR:12,15) days in the control group; The median times from onset to radiologic recovery in lungwere also no difference (P>0.05), with 12 (IQR: 10,15)days in the glucocorticoid group and 13 (IQR: 12,17) days inthe control group. Conclusions Low-to-moderate glucocorticoid treatment has no effect on the time of virus clearance in patients with different clinical types of COVID-19. The glucocorticoid is not recommended since no effectiveness on accelerating the improvement of radiologic recovery in lung has been observed.

All patients received oral arbidol and combination of lopinavir/ritonavir or darunavir/cobistitat for antiviral therapy, and symptomatic supportive care. Among them, 51 patients received methylprednisolone (0.75-1.50 mg·kg -1·d -1) (glucocorticoid treatment group), and 21 patients did not use glucocorticoid (control group). The time of virologic negative conversion in sputum and the time of radiologic recovery in lung since onset were compared between the two groups. The Kruskal-Wallis test or Fisher exact test was used to compare the difference between groups. Results:The median ages of the glucocorticoid group and the control group were 52 (45, 62) and 46 (32, 56) years ( χ2=4.365, P<0.05). The clinical conditions at hospital admission were different between the two groups ( P<0.01). The severe cases accounted for 52.0%, while moderate cases in the control group accounted for 71.4%. The median times from the onset to virologic negative conversion in the two groups were 15 (13, 20) and 14 (12, 20) days ( P>0.05). The median times from onset to radiologic recovery were 13 (11, 15) and 13 (12, 17) days in the two groups ( P>0.05). In moderate cases, the median times from the onset to virologic conversion in sputum were 13 (11, 18) days in the glucocorticoid group and 13 (12, 15) days in the control group ( P>0.05). The median times from onset to radiologic recovery in lung were 12 (10, 15) and 13 (12, 17) days, respectively ( P>0.05). Conclusions:Low-to-moderate glucocorticoid treatment has no effect on the time of virus clearance in patients with different clinical types of COVID-19, and also no effect on accelerating radiologic recovery in lung, so it is not recommended.
