OBJECTIVE: To investigate the short-term effectiveness of uni-portal non-coaxial spinal endoscopic surgery (UNSES) via crossing midline approach (CMA) in the treatment of free lumbar disc herniation (FLDH). METHODS: Between March 2024 and June 2024, 16 patients with FLDH were admitted and treated with UNSES via CMA. There were 9 males and 7 females with an average age of 55.1 years (range, 47-62 years). The disease duration was 8-30 months (mean, 15.6 months). The pathological segments was L _{3, 4} in 4 cases, L _{4, 5} in 5 cases, and L ₅, S ₁ in 7 cases. The preoperative pain visual analogue scale (VAS) score was 6.9±0.9 and the Oswestry disability index (ODI) was 57.22%±4.16%. The operation time, intraoperative bleeding volume, postoperative hospital stay, and incidence of complications were recorded. The spinal pain and functional status were evaluated by VAS score and ODI, and effectiveness was evaluated according to the modified MacNab criteria. CT and MRI were used to evaluate the effect of nerve decompression. RESULTS: All 16 patients underwent operation successfully without any complications. The operation time was 63-81 minutes (mean, 71.0 minutes). The intraoperative bleeding volume was 47.3-59.0 mL (mean, 55.0 mL). The length of hospital stay after operation was 3-4 days (mean, 3.5 days). All patients were followed up 1-3 months, with 15 cases followed up for 2 months and 14 cases for 3 months. The VAS score and ODI gradually decreased over time after operation, and there were significant differences between different time points ( P<0.05). At 3 months after operation, the effectiveness was rated as excellent in 12 cases and good in 2 cases according to the modified MacNab criteria, with an excellent and good rate of 100%. CT and MRI during follow-up showed a significant increase in the diameter and cross-sectional area of the spinal canal, indicating effective decompression of the canal. CONCLUSION When using UNSES to treat FLDH, choosing CMA for nerve decompression has the advantages of wide decompression range, large operating space, and freedom of operation. It can maximize the preservation of the articular process, avoid fracture and breakage of the isthmus, clearly display the exiting and traversing nerve root, and achieve good short-term effectiveness.

The emerging biomedical industry has an increasing demand for the professional talents and puts forward higher requirements for the quality, especially the innovation ability of the talents. Exploring a new model for fostering the innovation ability of postgraduates majoring in biological and medical sciences based on the principle of integrating production, education and research is of practical significance for improving the quality of professional talents and empowering the bio-economic development. Taking the training of innovation ability of postgraduates majoring in biological and medical sciences at Jiangnan University as an example, this paper introduced a new training system of "six integration and six optimizations". This system included ideological guidance, discipline system, training program, faculty, research innovation platform, and communication and cooperation. Satisfactory cultivation results were achieved with this new system. This paper is expected to provide reference for the training of innovative talents in the biological and medical industry.

Objective:To explore the effectiveness and safety of tirofiban in patients with reocclusive ischemic stroke after intravenous thrombolysis with alteplase.Methods:Eighty-four patients with re-occlusive ischemic stroke after intravenous thrombolysis with alteplase, admitted to our hospital from January 2018 to May 2020, were prospectively chosen; these patients were divided into tirofiban group and routine (non-tirofiban) group ( n=42). In addition to thrombolysis, patients in the routine group received intensive lipid-lowering, collateral circulation improvement, blood glucose control, and early rehabilitation therapy; after thrombolysis for 24 h, patients without intracranial hemorrhage were given oral aspirin, 0.1 g/d, for 90 d. After thrombolysis and re-occlusion, patients in the tirofiban group were intravenously pumped with 0.4 μg/(kg·min), which was changed to 0.1 μg/(kg·min) after 30 min for 24 h; at 24 h after thrombolysis, brain CT was reexamined: tirofiban was discontinued for patients with intracranial hemorrhage, and intravenous pumping of tirofiban was continued for patients without intracranial hemorrhage for 24 h. Effectiveness was evaluated by comparing the general clinical data, National Institutes of Health Stroke Scale (NIHSS) scores 7 d after treatment, and modified Rankin Scale (mRS) scores 90 d after treatment between the two groups. Safety was assessed by comparing the intracranial hemorrhage, symptomatic intracranial hemorrhage, and mortality within 90 d of treatment between the two groups. Results:There were no significant differences in age, gender, underlying diseases, risk factors, baseline NIHSS scores, time from onset to start of treatment, infarction sites, and TOAST classification between the 2 groups ( P>0.05). NIHSS scores 7 d after treatment ([10.05±4.73] min vs. [7.93±4.68] min), mRS scores 90 d after treatment (3.48±1.48 vs.2.55±1.93), and good prognosis rate 90 d after treatment (21.4% vs. 42.9%) showed significant differences between the routine group and tirofiban group ( P<0.05). In terms of safety, there were no significant differences in intracranial hemorrhage rate (4.76% vs. 7.14%), symptomatic intracranial hemorrhage incidence (2.38% vs. 2.38%) and mortality (2.38% vs. 2.38%) between the 2 groups ( P>0.05). Conclusion:It is safe and effective for tirofiban in patients with re-occlusive ischemic stroke after intravenous thrombolysis with alteplase.

Objective: To analyze the characteristics of changes in serum cholesterol level in sepsis patients, and to explore its correlation with prognosis. Methods: A retrospective analysis was conducted. Two hundred and six patients with sepsis admitted in the Third People′s Hospital of Dalian from February 2015 to February 2019 were enrolled (observation group), and 206 patients without sepsis hospitalized in the same period were served as control group. The basic clinical data of the two groups were collected, and the results of total cholesterol (TC), low density lipoprotein cholesterol (LDL-C), high density lipoprotein cholesterol (HDL-C) and biochemical parameters were compared. The patients with sepsis were divided into death group and survival group, and risk factors influencing the prognosis of patients with sepsis were analyzed with Logistic regression analysis. Results: Compared with control group, the levels of serum TC [(2.49 ± 1.14) mmol/L vs. (3.40 ± 1.26) mmol/L, t=6.240] and HDL-C [(1.66 ± 0.89) mmol/L vs. (2.49 ± 0.81) mmol/L, t=5.532] in observation group were significantly lower (P<0.05), and that of LDL-C showed no statistically significant difference [(1.96 ± 0.91) mmol/L vs. (2.10 ± 0.72) mmo/L, t=0.940, P>0.05]. In observation group, the patients in death group (85 cases) were older than those of the survival group (121 cases)[(75.6 ± 8.6) years vs. (62.5 ± 6.0) years, t=4.565], serum creatinine (SCr) was higher than that of survival group [(246.2 ± 34.6) μmol/L vs. (165.4 ± 35.6) μmol/L, t=5.420], and the levels of serum TC [(2.15 ± 0.59) mmol/L vs. (2.89 ± 1.02) mmol/L, t= 5.475], HDL-C [(1.40 ± 0.42) mmol/L vs. (1.94 ± 0.52) mmol/L, t=4.856] and LDL-C [(1.73 ± 0.56) mmol/L vs. (1.97 ± 0.72) mmol/L, t=4.261] were significantly lower than those of survival group (P<0.05). Logistic regression analysis showed that age was the risk factor of death in sepsis patients (OR=1.256, 95% CI 1.006 -1.056, P=0.012), and TC was the protective factor for the prognosis of sepsispatients (OR=-0.758, 95%CI 0.579-0.867, P=0.014). Conclusions The levels of TC, HDL-C in sepsis patients are significantly lowered, and the levels of TC, HDL-C, LDL-C in death group are significantly lower than those in survival group. TC may be used as a clinical indicator to assess the outcome of sepsis patients.
