Objective Feasibility application of microelectrode recording(MER)during sub thalamic nucleus deep brain stimulation(STN-DBS)implantation under desflurane general anesthesia(GA)in patients with Par-kinson's disease(PD).Methods A prospective cohort of 20 PD patients undergoing STN-DBS under desflurane general anesthesia were enrolled.Intraoperative MER quality,pos-operative acute pain,cognitive function,anxi-ety/depression status,quality of life,and clinical efficacy of DBS were evaluated.Results Among the patients,14 were male with average PD duration of(8.1±3.6)years.Hoehn-Yahr staging averaged 2.8±0.5 in"on"state and 2.3±0.5 in"off"state.The mean DBS surgery duration was 87.4 minutes.Highly normalized root-mean-square(NRMS)signals were successfully recorded in all cases,with remedial measures applied in 4 pa-tients to achieve satisfactory MER signals.Post-operative Visual Analogue Scale(VAS)pain scores on days 1,2,and 3 were 3.7±2.2,2.8±1.6,and 1.8±2.0,respectively.Montreal Cognitive Assessment(MoCA)scores showed no statistical difference during hospitalization as compared to pre-operative values,but significantly de-creased at 6-month follow-up(24.3±4.1 vs.21.5±3.5,P＜0.05).All patients demonstrated significant reduc-tion in Hamilton Anxiety Scale(HAMA),Hamilton Depression Rating Scale(HAMD),and Parkinson's disease Questionnaire-39(PDQ-39)scores at 6-month follow-up.The unified Parkinson's disease rating scale(UPDRS-Ⅲ)improvement rates were 51.4%±39.2%(medication-on)and 61.6%±26.8%(medication-off)respectively with Levodopa Equivalent Daily Dose(LEDD)improvement rate of 48.6%±23.0%.Conclusions Desflurane general anesthesia is safe and feasible for electrods implantation in STN-DBS of PD patients,without interfering with intra-operative MER or postoperative outcomes.

The incidence of thyroid cancer has been increasing,and early diagnosis and treatment are crucial for improving patient prognosis.With the advancement of artificial intelligence(AI)technology,significant progress has been made in its application in the diagnosis and treatment of thyroid cancer.AI technology has notably enhanced the diagnostic accuracy of thyroid cancer.By optimizing imaging examinations such as ultrasound and CT scans,it can more precisely identify malignant features of thyroid nodules.In fine-needle aspiration biopsy,the integration of AI with genetic testing technologies has improved both the accuracy and efficiency of diagnosis.In terms of treatment,AI assists in intraoperative functional preservation,reducing the risk of surgical trauma.For instance,it can accurately identify the locations of the recurrent laryngeal nerve and parathyroid glands.Additionally,AI is capable of predicting the efficacy of 131I treatment and the risk of complications,thereby guiding postoperative follow-up and management.The core strength of AI technology lies in its powerful data processing and analytical capabilities,enabling it to uncover latent patterns within data and provide a scientific basis for treatment decision-making.Looking ahead,with continuous technological advancements,AI is expected to propel the diagnosis and treatment of thyroid cancer towards greater intelligence and precision.However,challenges such as data privacy and algorithm transparency need to be addressed.This article provides a review of the research progress of AI technology in the fields of diagnosis,treatment,and prognosis prediction of thyroid cancer,explores the current strengths and weaknesses of AI technology,and looks forward to its future development directions while acknowledging challenges like data privacy and algorithm transparency.

Mesh-related visceral complications caused by mesh erosion after tension-free inguinal hernia repair are one kind of rare long-term complications, but they are easily neglected. Interval time from initial hernia repair to mesh-related visceral complications by preperitoneal and laparoscopic repair is short. Rutkow and transabdominal preperitoneal repair have the highest reported rate. Lichtenstein has the longest interval time and the lowest reported rate. The most frequently eroded organs are sigmoid colon, bladder and small intestine. The common clinical manifestations of sigmoid colon erosion are hematochezia, abdominal wall fistula and colitis, hematuria and recurrent urinary tract infection in bladder erosion cases, intestinal obstruction and abdominal wall fistula in intestinal erosion case, sigmoid-bladder fistula and intestinal-bladder fistula in multiple organ erosion cases. Resection or repair of corresponding organs with mesh removal have good efficacies in most patients. The authors summarize and analyze researches on mesh-related visceral complications after tension-free inguinal hernia repair from 1994 to 2021, review their advances, in order to raise awareness of such complications in clinicians.

Objective:To study the migration of polyploid tumor cells induced by docetaxel, the characteristics of epithelial-mesenchymal transition, and the killing effect of immune cells on them, in order to explore the potential role of polyploid tumor cells in tumor recurrence.Methods:The human non-small cell lung cancer A549 cells were treated with 1 μmol/L docetaxel for 24 h, and the cells were collected as Doc 1 d group. After drug removal, the cells were cultured in fresh and complete medium for 3 or 5 days, then the cells were collected as Doc 3 d group or Doc 5 d group respectively. The A549 cells were treated with DMSO for 24 h as control group. Immunofluorescence staining was used to detect cell morphology, flow cytometry was used to analyze cell ploidy, scratch test was used to detect cell migration, Western blotting was used to detect the expression of epithelial-mesenchymal transition related proteins, and lactate dehydrogenase release method was used to evaluate the killing activity of cytokine-induced killer (CIK) cells.Results:Compared with the control group, most of the cells in the Doc 1 d group, Doc 3 d group and Doc 5 d group were apoptotic, a few of the surviving cells were significantly larger, and the nucleus was polynuclear. The proportions of polyploid cell subset (DNA content > 4N) in the control group, Doc 1 d group, Doc 3 d group and Doc 5 d group were (1.93±0.55)%, (22.97±2.37)%, (51.30±12.51)% and (67.87±8.31)% respectively, and the difference among the four groups was statistically significant ( F=26.521, P<0.001). The proportion of polyploid cell subset in Doc 1 d group, Doc 3 d group and Doc 5 d group was significantly higher than that in the control group (all P<0.001). With the prolongation of withdrawal time, the proportion of polyploid cell subset in Doc 3 d group and Doc 5 d group was significantly higher than that in Doc 1 d group ( P=0.009; P=0.004). After 24 h and 48 h culture, the wound healing rates of the control group were both 100%, and the wound healing rates of the Doc 3 d group were (39.10±2.12)% and (46.13±5.32)% respectively, with no significant difference ( t=2.126, P=0.051). Compared with the control group at 24 h and 48 h, the cell migration abilities of Doc 3 d group were significantly lower ( t=49.756, P<0.001; t=30.825, P<0.001). Compared with the control group, the expression of E-cadherin protein decreased gradually in the Doc 1 d group, Doc 3 d group and Doc 5 d group, the expression of Vimentin protein increased gradually, and the expressions of Snail protein and N-cadherin protein did not change significantly. The killing efficiencies of CIK cells against the cells of the control group, Doc 3 d group and Doc 5 d group were (27.27±1.91)%, (17.87±2.35)%, (9.47±0.51)% respectively, and the difference was statistically significant ( F=11.294, P<0.001). The killing efficiency of Doc 3 d group and Doc 5 d group was significantly lower than that of the control group ( P=0.004; P<0.001). The killing efficiency of Doc 5 d group was significantly lower than that of Doc 3 d group ( P=0.003). Conclusion:The migration ability of polyploid tumor cells induced by docetaxel is weakened, but epithelial-mesenchymal transition is likely to occur, and the killing effect of immune cells on them is reduced.

Objective To investigate the effects of transcutaneous electrical acupoint stimulation (TEAS) and electro-acupuncture (EA) combined with local anesthesia on cerebral blood flow (CBF) and Brain function in CAS patients.Methods Eighty cases of CAS were randomly as signed into EA group (group A),TEAS group (group T) and sham group (group C).Patients in group A received EA at acupoints of Shuigou (GV26) and Baihui (GV20),Hegu (L14) and Waiguan (TE5) at the same side of the stenting before 30 min of operation.Patients in group T received TEAS at the same acupoints through self-adhesive skin electrodes.In group T and group A,stimulations were continued until the end of the operation.The patients in group C did not received EA or TEAS.Blood pressure (BP) and heart rate (HR) were maintained at + 10％-20％ of baseline.Preoperative and postoperative average Vm,PI,RI of middle cerebral artery were measured.The occurrence of hyperperfusion and preoperative and postoperative scores at 1 week,1 month,3 months National Institute of Health Stroke Scale and Global Assessment Scale were recorded.Results The Vm of groups A and T was significantly less than group C (P＜0.05).The incidence of hyperperfusion of groups A and T were 3.7％,0％ and 25.0％ respectively (P＜0.05).NIHSS score of group A and group T were lower than those of group C during postoperative 1 week,1 month,3 month (P＜0.05),while the difference between groups A and T had no statistical significance.GES score of group A and group T during postoperative 1 week improved significantly than that of group C (P＜0.05).Conclusion Both TEAS and EA combined with local anesthesia in CAS operation could reduce the increase of postoperative cerebral blood flow and the incidence of postoperative hyperperfusion,and obviously improve brain function during postoperative 1 week.Both TEAS and EA combined with local anesthesia could be a worthwhile anesthesia method in CAS patients.
