Objective:To evaluate the accuracy and safety profile of a novel cuboid orientation-guided frontal horn ventriculostomy technique in patients with large hemispheric infarction (LHI).Methods:It was conducted a retrospective cohort study of 48 consecutive LHI patients who underwent the innovative ventriculostomy procedure between time period. Primary outcomes included procedural accuracy (success rates, catheter positioning) and safety indicators (complication rates).Results:All the punctured ventricles were small or of normal size. The success rate of puncture was 100%, the success rate of one-time puncture was 87% (42/48), and the average number of puncture was 1.13 times per case. The ratio of well-positioned tube heads was 87.5% (42/48). The actual angle of the inward deviation of the puncture ranged from -2o to 5o, with an average of 0o±0.3o. The depth of puncture was 7.0-8.0 cm ( 7.3±0.3) cm. The incidence of bleeding around the puncture path was 1.3% (2/48 ) and no massive bleeding occurred. At the 6-month follow-up, one case (2.94%) among the 34 survivors had epilepsy.Conclusions:The cuboid orientation-guided frontal horn ventriculostomy technique demonstrates exceptional procedural accuracy and an excellent safety profile in LHI patients, with high first-pass success rates (87.5%) and minimal complications (4.2% minor hemorrhage). These findings support its clinical adoption for this patient population.

Objective:To explore the effect and safety of stereotactic aspiration of necrotic brain tissue for the patients≥61 years with malignant middle cerebral artery infarction (MMI).Methods:A total of 102 MMI patients aged≥61 years were enrolled retrospectively. All patients were subject to conservative medical treatment alone or in addition to stereotactic aspiration of necrotic brain tissue 24-72 hours after symptom onset. Perioperative outcomes and 6-month follow-up outcomes were observed and evaluated.Results:Baseline data characteristics were well balanced between the conservative treat group and aspiration group, except for the prevalence of hypertension. The incidence of early cerebral herniation (9.1% vs. 48.3%, χ2=17.843, P<0.001) and death (13.6% vs. 60.3%, χ2=22.707, P<0.001)in the aspiration group was significantly lower than that in the conservative group, and there was no significant difference in the incidence of cerebral hemorrhage ( P=0.726) and intracranial infection ( P=0.186) between the groups. At 6-month follow-up, compared with the conservative treatment group, the aspiration group had a higher proportion of favorable outcome (mRS 0-3) (38.6% vs. 3.4%, χ2 =20.438, P<0.001) and survival without severe disability (mRS 0-4) (68.2% vs. 22.4%, χ2=21.492, P<0.001). Comparison of clinical characteristics of favorable outcome (mRS 0-3) group and unfavorable (mRS 4-6) group showed that the proportion of patients treated with aspiration was significantly higher than that treated with medical therapy alone (89.5% vs. 10.5%, P<0.001). Multivariate logisitic regression used to adjust the confound factors such as atrial fibrillation, diabetes and smoking, the GCS and the NIHSS score of 24 hours after onset, etc, revealed that the treatment with aspiration was an independent association factor for the ratio of 6-month favorable outcome for the elderly patients with MMI ( OR=126.704, 95% CI: 7.236-2218.610, P<0.001). Conclusions:The stereotactic aspiration of necrotic brain tissue are effective and safe for the elderly patients with MMI.

Objective:To explore the efficacy and safety of TiRobot combined with three-dimensional imaging in the minimally invasive surgery for pelvic fractures.Methods:A retrospective analysis was conducted of the 40 patients with pelvic fracture who had been treated by fixation with S1 and S2 sacroiliac screws at Department of Orthopaedics and Traumatology, Yangjiang People's Hospital from January 2019 to May 2021. They were divided into 2 groups according to their treatment methods. In the TiRobot group of 20 cases subjected to percutaneous sacroiliac screw fixation assisted by TiRobot combined with three-dimensional imaging, there were 13 males and 7 females with an age of (38.2 ± 8.8) years. In the manual group of 20 cases subjected to fixation with manual placement of sacroiliac screws under conventional C-arm fluoroscopy, there were 11 males and 9 females with an age of (37.3 ± 9.2) years. The 2 groups were compared in terms of fluoroscopy time for screw placement, guide needle adjustment, operation time, intraoperative blood loss, visual analogue scale (VAS) 72 hours after operation, postoperative hospital stay, time to ambulation, excellent to good rate of screw placement, complication rate, fracture union time, Majeed score at 6 months after operation, and excellent to good rate of functional evaluation.Results:There was no significant difference between the 2 groups in their preoperative general data, showing they were comparable ( P > 0.05). In the TiRobot group, fluoroscopy time for screw placement [(8.2 ± 2.9) s], guide needle adjustment [(0.4 ± 0.2) times], operation time [(67.4 ± 5.5) min], and intraoperative blood loss [(36.5 ± 8.0) mL] were significantly less than those in the manual group [(40.4 ± 4.5) s, (8.6 ± 0.7) times, (78.4 ± 7.2) min, and (41.6 ± 7.8) mL], postoperative VAS [3.0 (4.0, 5.0) points] was significantly lower than that in the manual group [4.0 (5.0, 6.0) points], the excellent to good rate of screw placement (100%, 40/40) was significantly higher than that in the manual group (85.0%, 34/40), and the complication rate (5.0%,1/20) was significantly lower than that in the manual group (35.0%, 7/20) (all P < 0.05). There was no significant difference between the 2 groups in postoperative hospital stay, time to ambulation, fracture union time, Majeed score, or excellent to good rate of functional evaluation ( P > 0.05). Conclusion:In the minimally invasive surgery for pelvic fractures, TiRobot combined with three-dimensional imaging leads to positive outcomes, because it can reduce operation time and radiation exposure, improve accuracy of screw placement, and increase safety.

Objective:To analyze and compare VP1 and VP4 genetic characteristics of human enterovirus 71(EV71) isolated from children with severe and mild hand-foot and mouth disease(HFMD).Methods:EV71 strains isolated from severe HFMD patients (6 cases) and mild HFMD patients (6 cases) in Taizhou district, Zhejiang province were included during 2016.Total virus RNA was extracted by Viral RNA Mini Extraction Kit, and reverse transcription polymerase chain reaction(RT-PCR) was used to amplify the sequence of the VP1 and VP4 genes of EV71.And then the sequencing results were compared with those of A, B, C genotype reference EV71 strains from GenBank by nucleotide alignment and amino acid alignment analysis.Results:There were no statistically significant differences in sex and age between the two groups(χ 2=14.51, t=2.82, all P<0.05). The homogeneity between EV71 strains from severe patients and mild patients was 95.8%~99.6% and 99.1%~100.0% for VP1 nucleotide sequences and amino acid sequences, respectively, while 95.0%~99.9% and 99.0%~100.0% for VP4 nucleotide sequences and amino acid sequences, respectively.The twelve EV71 strains isolated from HFMD patients in Taizhou shared the highest identity with EV71-genotype C, especially genotype C4a.In addition, compared with the mild patients, three respective strains from severe HFMD patients showed mutations at the residue 170 in the VP1 protein(V→L), residue 293 in the VP1 protein(A→S) and residue 7 in the VP4 protein(T→A). Conclusion:All EV71 strains isolated from severe and mild HFMD patients in Taizhou district share high homology of nucleotide and amino sequence, and all of them belong to subgenogroup C4a.The mutations in the VP1 and VP4 of EV71 might be related to HFMD disease severity.

OBJECTIVE: To evaluate the efficacy of endoscopic minitrephination combined with endoscopic frontal sinusotomy in the management of complex chronic frontal sinusitis. METHOD: Twenty-six patients suffering from chronic frontal sinusitis with complex frontal drainage approach were analyzed. Eleven patients (13 sides) received endoscopic minitrephination combined with endoscopic frontal sinusotomy, while the other 15 patients (18 sides) received endoscopic frontal sinusotomy only. Postoperatively all cases were followed up to evaluate the efficacy. RESULT: The ostia of frontal sinus were successfully opened in the group of patients received endoscopic minitrephination combined with endoscopic frontal sinusotomy without any complications. In the endoscopic frontal sinusotomy only group, three cases of complications were observed, one with the injury of anterior ethmoidal artery and the other two with the injury of papyraceous lamina. After 10 to 24 months of follow up postoperatively, the symptoms were relieved in all cases without recurrence. The combined surgery group with endoscopic minitrephination showed an endoscopic frontal sinus patency rate of 85%, and the endoscopic frontal sinusotomy only group exhibited an endoscopic frontal sinus patency rate of 83%. CONCLUSION Endoscopic minitrephination combined with endoscopic frontal sinusotomy is a simple, convenient, safe and effective method for management of complex chronic frontal sinusitis.
