Objective To evaluate the therapeutic efficacy for surgical treatments among patients with hepatic cystic echinococcosis in Gansu Province from 2006 to 2023, so as to provide insights into optimization of the diagnosis and treatment strategies against hepatic cystic echinococcosis. Methods The demographic and clinical data of all echinococcosis cases included in central government fiscal transfer payment program for echinococcosis control and undergoing surgical treatments in Gansu Province from 2006 to 2023 were captured. Hepatic cystic echinococcosis patients with complete medical records and follow-up data were included in the study, and patients’ characteristics, including hospital where patients received diagnosis and treatment, methods of case identification, year of surgery, classification of lesions, number of lesions, size of lesions, course of disease, surgical methods, and post-surgical follow-up data. The cure and recurrence of hepatic cystic echinococcosis were evaluated according to the Guidelines for Management of Echinococcosis Patients in the Central Government Fiscal Transfer Payment Program, and the cure and recurrent rates were calculated. Results Data were collected from 1 686 surgical patients with hepatic cystic echinococcosis. According to the inclusion and exclusion criteria, 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments were included during the period from 2006 to 2022, including 1 166 cured patients (95.42%) and 88 patients with postsurgical recurrence (7.20%), and the cure rate of surgical treatments appeared a tendency towards a rise among patients with hepatic cystic echinococcosis from 2008 to 2022 (χ²_trend = 19.39, P < 0.05). The cure rates of hepatic cystic echinococcosis were 100% (177/177), 94.81% (128/135) and 94.62% (861/910) among patients detected through regular physical examinations, screened by the central government fiscal transfer payment program for echinococcosis control, and those who passively sought healthcare services, respectively (χ² = 9.95, P < 0.05). The cure rates of hepatic cystic echinococcosis were 95.96% (1 046/1 090) among patients with a disease course of 2 years and less and 90.90% (120/132) among patients with a disease course of over 2 years (χ² = 6.87, P < 0.05), and there were significant differences in the cure rates among patients with hepatic cystic echinococcosis in terms of number of lesions (χ² = 24.44, P < 0.05) and surgical methods (P < 0.05). The cure rate of hepatic cystic echinococcosis patients was significantly higher following initiation of the central government fiscal transfer payment program for echinococcosis control (96.06%, 1 096/1 141) than before the program (86.42%, 70/81) (χ² = 16.06, P < 0.05), and the cure rate of hepatic cystic echinococcosis patients was significantly higher in designated hospitals (96.48%, 741/768) than in non-designated hospitals (93.37%, 366/392) (χ² = 5.78, P < 0.05). The median follow-up period was 4 (interquartile range, 7) years among 1 222 hepatic cystic echinococcosis patients undergoing surgical treatments. The recurrent rate of hepatic cystic echinococcosis appeared a tendency towards a decline from 2008 to 2022 (χ²_trend = 36.86, P < 0.05), with a reduction from 23.08% (9/39) in 2008 to 1.85% (1/54) in 2021, and the post-surgical recurrence rate of hepatic cystic echinococcosis was lower following initiation of the central government fiscal transfer payment program for echinococcosis control (5.87%, 67 / 1 141) than before the program (25.93%, 21/81) (χ² = 45.51, P < 0.05). In addition, the post-surgical recurrence rate of hepatic cystic echinococcosis was higher in non-designated hospitals (10.46%, 41/392) than in designated hospitals (5.60%, 43/768) (χ² = 9.12, P < 0.05), and there was a significant difference in the post-surgical recurrence rate among patients with hepatic cystic echinococcosis in terms of surgical methods (P < 0.05), with the highest recurrence rate (11.54%) seen among patients undergoing percutaneous fine-needle aspiration of cyst fluids-based surgical procedures (P < 0.05). Conclusion Since the initiation of the central government fiscal transfer payment program for echinococcosis control in Gansu Province in 2006, an increase in the surgical cure rate and a reduction in the recurrence of hepatic cystic echinococcosis had been found among patients with hepatic cystic echinococcosis, indicating a high overall therapeutic efficacy.

Objective·To investigate the application effects and benefits of full-neuroendoscopic technique in the surgical treatment of posterior cranial fossa lesions.Methods·A retrospective analysis was conducted on the clinical data of 105 patients with posterior cranial fossa lesions who underwent surgery using full-neuroendoscopic techniques at the Department of Neurosurgery,Renji Hospital,Shanghai Jiao Tong University School of Medicine,between January 2021 and December 2023.The data included patients'gender,age,lesion locations,nature of lesions,surgical procedures,and postoperative recovery.Follow-up with contrast-enhanced MRI was performed one month postoperatively,with subsequent follow-ups every three months on average,depending on the nature of the lesions.Results·Among the 105 patients,there were 45 males with an average age of(56±17)years and 60 females with an average age of(62±12)years.Lesions were predominantly located in the cerebellopontine angle area(78 cases),with others in the petrous bone area(7 cases),cerebellum(10 cases),and brainstem(10 cases).The nature of lesions included vestibular schwannoma(11 cases),meningioma(7 cases),glioma(7 cases),brain metastases(7 cases),hemangioblastoma(6 cases),cyst(1 case),and neuropathic conditions such as trigeminal neuralgia(43 cases),hemifacial spasm(22 cases),and glossopharyngeal neuralgia(1 case).All patients successfully underwent resection or biopsy of their lesions or microvascular decompression under full-neuroendoscopy.The follow-up period ranged from 3 months to 3 years.Enhanced MRI confirmed complete resection in 34 tumor cases(87.2％),near-total resection in 3 cases(7.7％),and biopsy in 2 cases(5.1％).Three deaths occurred during follow-up.Among the patients with vascular neuropathic diseases,two with trigeminal neuralgia experienced incomplete pain relief postoperatively.The resolution rates for hemifacial spasm and glossopharyngeal neuralgia were 100％.Postoperative complications occurred in 3 cases,with 2 cases of hydrocephalus that were managed with ventriculoperitoneal shunting,and 1 case of poor wound healing.Conclusion·Full-neuroendoscopic technique demonstrates potential in the surgical treatment of posterior cranial fossa lesions.

Objective To investigate the effect and mechanism of Taxilli Herba decoction in preventing miscarriage in rats with threatened abortion.Methods Seventy-two SPF-grade SD rats were co-housed at a male-to-female ratio of 2∶1.Forty-eight pregnant rats were subsequently divided into a normal group,a threatened abortion model group,a positive control group,as well as Taxilli Herba decoction low/medium/high dose groups(n=8 rats per group).Rats in the positive control group received 3.02 mg/kg dydrogesterone intragastrically,and rats in the low-,medium-,and high-dose Taxilli Herba decoction groups received 2.5,5,and 10 g/kg Taxilli Herba decoction intragastrically,respectively.The normal and model groups received intragastric distilled water once a day for 10 consecutive days.On day 10 after administration of the corresponding treatment,rats in all groups except the normal group received intragastric administration of 3.75 mg/kg mifepristone suspension.The effects of Taxilli Herba on the vaginal bleeding rate and abortion rate were observed.Serum levels of follicle-stimulating hormone(FSH),luteinizing hormone(LH),estrogen(E),progesterone(P),vascular endothelial growth factor(VEGF),testosterone(T),and aromatase and E and P levels in the ovary in pregnant rats were detected by enzyme-linked immunosorbent assay.Expression levels of E receptor(ER),P receptor(PR),VEGF receptor 2(VEGFR2),and platelet endothelial cell adhesion molecule-1(CD31)in the uterine decidua in pregnant rats were detected by immunofluorescence staining,and semi-quantitative analysis was performed.Results Mifepristone significantly increased the vaginal bleeding rate and abortion rate in pregnant rats,but these were effectively reduced by treatment with Taxilli Herba water decoction.Taxilli Herba water decoction also increased serum E,P,and VEGF,and ovary levels of E and P(P＜0.05).The treatment also decreased serum LH,maintained the secretion of FSH,and enhanced ER,PR,VEGFR2,and CD31 expression in decidual tissue.Conclusions Taxilli Herba demonstrated effective miscarriage-prevention effects in a rat model of threatened abortion.Its mechanism of action involves regulating the normal physiological function of the hypothalamic-pituitary-gonadal axis upstream of the uterus,and enhancing the expression of the downstream P/PR/VEGF/VEGFR2 and E/ER/VEGF/VEGFR2 pathways.

Objective To explore the relevant relationship and specificity between the implicit and explicit loyalty of military cadets in order to provide a theoretical basis and objective indicators for a more comprehensive and objective assessment for individual loyalty.Methods E-Prime 2.0,a classic implicit association paradigm was employed to construct an implicit association loyalty test for 64 military cadets.Simultaneously,an explicit loyalty measurement was conducted using the Chinese Military Personnel Loyalty Scale.Results ① Significant implicit effect was observed in the loyalty assessment of military cadets,indicating a general tendency to perceive higher levels of personal loyalty and lower levels of loyalty to external entities.② Explicit loyalty assessment revealed that the participants had the highest loyalty score towards the Party,the Nation,and the People(4.79±0.34),followed by the loyalty score to their profession(4.38±0.53),and the relatively lower loyalty score towards the unit and leaders(4.03±0.83).Among the 3 dimensions of loyalty,the normative loyalty score ranked highest,while continuance loyalty score took lower.③ There were no correlations among the scores of loyalty to the Party,the Nation,and the People(r=-0.030,P=0.823),to the profession(r=-0.047,P=0.728),to the unit(r=0.050,P=0.710),or to the leaders(r=0.043,P=0.749).Conclusion The implicit effect in the loyalty assessment is significant in military cadets,and there is no significant correlation between explicit and implicit loyalty measurements.Thus,we cannot rely solely on explicit measurements to assess their loyalty attitudes.

The incidence of osteoporotic thoracolumbar vertebral fracture (OTLVF) in the elderly is gradually increasing. The kyphotic deformity caused by various factors has become an important characteristic of OTLVF and has received increasing attention. Its clinical manifestations include pain, delayed nerve damage, sagittal imbalance, etc. Currently, the definition and diagnosis of OTLVF with kyphotic deformity in the elderly are still unclear. Although there are many treatment options, they are controversial. Existing guidelines or consensuses pay little attention to this type of fracture with kyphotic deformity. To this end, the Lumbar Education Working Group of the Spine Branch of the Chinese Medicine Education Association and Editorial Committee of Chinese Journal of Trauma organized the experts in the relevant fields to jointly develop Clinical guidelines for the diagnosis and treatment of osteoporotic thoracolumbar vertebral fractures with kyphotic deformity in the elderly ( version 2024), based on evidence-based medical advancements and the principles of scientificity, practicality, and advanced nature, which provided 18 recommendations to standardize the clinical diagnosis and treatment.

Objective:To evaluate the effect of autologous hematopoietic stem cell transplantation (ASCT) on the treatment of relapsed/refractory multiple myeloma (RRMM) with chimeric antigen receptor T cell (CAR-T) therapy.Methods:A retrospective cohort study. The clinical data of 168 patients with RRMM who underwent CAR-T therapy at the Department of Hematology, Xuzhou Medical University Hospital from 3 January 2020 to 13 September 2022 were analyzed. Patients were classified into a transplantation group (TG; n=47) and non-transplantation group (NTG; n=121) based on whether or not they had undergone ASCT previously. The objective response rate (ORR), progression-free survival (PFS), overall survival (OS) and the levels of CD3, CD4, CD8, CD19, CD56 and natural killer (NK) cells before CAR-T infusion were analyzed by χ2 test, Kaplan-Meier method and independent sample t-test. Results:Among 168 patients with RRMM, 98 (58.3%) were male. The median age of onset was 57 (range 30-70) years. After CAR-T therapy, the ORR of patients was 89.3% (92/103) in the NTG and 72.9% (27/73) in the TG. The ORR of the NTG was better than that of the TG ( χ2=5.71, P=0.017). After 1 year of CAR-T therapy, the ORR of the NTG was 78.1% (75/96), and that of the TG was 59.4% (19/32). The ORR of the NTG was better than that of the TG ( χ2=4.32, P=0.038). The median OS and PFS in the NTG were significantly longer than those in the TG (OS, 30 vs. 20 months; PFS, 26 vs. 12 months; both P<0.05). The CD4 level before CAR-T infusion in the TG was significantly lower than that in the NTG (25.65±13.56 vs. 32.64±17.21; t=-2.15, P=0.034), and there were no significant differences in the counts of CD3, CD8, CD19, CD56, and NK cells between the TG and NTG (all P>0.05). Conclusion:Among patients suffering from RRMM who received CAR-T therapy, patients who did not receive ASCT had significantly better outcomes than those who had received ASCT previously, which may have been related to the CD4 level before receiving CAR-T therapy.

Objective:To evaluate the efficacy between pedicle screws combined with vertebroplasty (PSV) and pedicle screws combined with intermediate screws (PSIS) for the treatment of osteoporotic thoracolumbar fracture (OTLF).Methods:PubMed, Cochrane Library, Web of Science, CNKI, VIP and Wanfang database were searched for all randomized controlled trial (RCT) or case-control trial (CCT) studies that comparing PSV and PSIS for the treatment of OTLF. Two reviewers independently screened the studies in the light of the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. The Meta-analysis was performed using the RevMan 5.4 software. The subjects were divided into PSV group and PSIS group according to different treatment methods. Operation time, intraoperative blood loss, postoperative incision infection rate, postoperative short-, mid- and long-term visual analogue scale (VAS) score, postoperative short- and mid-term Oswestry disability index (ODI), hospitalization time, postoperative short-, mid- and long-term Cobb angle, postoperative short-, mid- and long-term anterior vertebral height ratio (VBH) and implant failure rate were compared between the two groups.Results:A total of 12 studies were enrolled for review, involving 870 subjects (433 in PSV group and 437 in PSIS group). The results showed insignificant difference between the two groups in operation time ( WMD=7.07, 95% CI -4.00, 18.13, P>0.05), intraoperative blood loss ( WMD=0.62, 95% CI -7.19, 8.43, P>0.05), postoperative incision infection rate ( OR=0.65, 95% CI 0.10, 4.08, P>0.05), postoperative short-term Cobb angle ( WMD=-0.19, 95% CI -0.43, 0.05, P>0.05) and postoperative short-term VBH ( WMD=0.91, 95% CI -1.30, 3.13, P>0.05). However, there was significant difference between the two groups in postoperative short-term VAS score ( WMD=-0.59, 95% CI -1.02, -0.15, P<0.05), mid-term VAS score ( WMD=-0.41, 95% CI -0.65, -0.16, P<0.05), long-term VAS score ( WMD=-0.51, 95% CI -0.59, -0.43, P<0.05), postoperative short-term ODI ( WMD=-6.26, 95% CI -9.65, -2.87, P<0.05), postoperative mid-term ODI ( WMD=-2.44, 95% CI -3.43, -1.45, P<0.05), hospitalization time ( WMD=-2.65, 95% CI -4.61, -0.68, P<0.05), postoperative mid-term Cobb angle ( WMD=-1.40, 95% CI -2.41, -0.39, P<0.05), postoperative long-term Cobb angle ( WMD=-1.06, 95% CI -1.59, -0.52, P<0.05), postoperative mid-term VBH ( WMD=3.06, 95% CI 1.31, 4.81, P<0.05), postoperative long-term VBH ( WMD=4.11, 95% CI 2.44, 5.77, P<0.05) and implant failure rate ( OR=2.06, 95% CI 0.11, 0.59, P<0.05). Conclusion:Compared with PSIS, PSV can not reduce the operation time, intraoperative blood loss and incision infection in the treatment of OTLF, but it can significantly relieve pain, improve function, decrease reduce hospitalization time, help to maintain Cobb angle and anterior vertebral height after operation, and reduce implant failure rate.

Objective:To compare the efficacy of percutaneous vertebroplasty (PVP) in the treatment of osteoporotic lumbar compression fracture (OLCF) via the approach through midpoint transverse process-transition zone of articular process and the unilateral transpedicular approach.Methods:A prospective cohort study was conducted to analyze the clinical data of 794 patients with OLCF treated in Honghui Hospital affiliated to Xi′an Jiaotong University School of Medicine from January 2017 to December 2019. The patients were divided into transitional-zone puncture group (400 patients, 400 vertebrae) and pedicle puncture group (394 patients, 394 vertebrae) according to the envelope method. The transitional-zone puncture group was treated with PVP via the approach through midpoint transverse process-transition zone of articular process, and the pedicle puncture group was treated with PVP via the unilateral transpedicular approach. The operation time and radiation dose were documented. The visual analogue score (VAS) and Oswestry dysfunction index (ODI) were evaluated before operation and at 1 day, 3 months, 1 year after operation. The cement distribution and the incidence of complications such as cement leakage, re-fracture of the injured vertebra, spinal cord nerve injury and facet joint injury were detected.Results:The patients were composed of 270 males and 524 females, at the age of 68.9-78.5 years [(73.7±4.8)years]. All patients were followed up for 12-14 months [(13.4±0.8)months]. The operation time and radiation dose in transitional-zone puncture group were reduced compared with pedicle puncture group ( P<0.01). There was no significant difference in VAS and ODI between the two groups before operation (all P>0.05). The VAS between transitional-zone puncture group [(2.1±0.9)points, (2.3±1.1)points, (2.7±1.3)points] and pedicle puncture group [(2.3±0.7)points, (2.5±0.9)points, (2.9±1.1)points] was obviously reduced from that before operation (all P<0.01), significantly different at 1 day, 3 months, 1 year after operation ( P<0.05 or 0.01). The ODI between transitional-zone puncture group (14.3±1.8, 13.6±3.4, 11.3±4.4) and pedicle puncture group (25.5±5.7, 20.7±6.3, 20.6±6.9) was significantly different at 1 day, 3 months, 1 year after operation (all P<0.01), and all were obviously reduced from that before operation (all P<0.01). With regard to the cement distribution, the number of bilaterally cemented vertebrae in transitional-zone puncture group (324) was more than that in pedicle puncture group (94) ( P<0.01). The incidence of cement leakage, re-fracture of the injured vertebra and facet joint injury was 8.25%(22/400), 0.00%(0/400) and 3.25%(13/400) in transitional-zone puncture group, significantly different from 20.81%(82/394), 2.03%(8/394) and 9.90%(39/394) in pedicle puncture group ( P<0.05 or 0.01). There was no significant difference in spinal cord nerve injury between the two groups ( P>0.05). Conclusion:For OLCF, PVP via the approach through the midpoint transverse process-transition zone of articular process and the unilateral transpedicular approach are both effective, but the former has advantages of shorter operation time, smaller radiation dose, greater dispersion of bone cement and lower incidence of cement leakage, re-fracture of the injured vertebra and facet joint injury.
