This paper develops an application and appraisal system for new technologies and projects based on No.1 Military Medical Project. With this system, all application and appraisal work can be performed through network so that the appraisal efficiency is raised and the traditional management of scientific research is infused new energy.

Objective: To study the influence of negative electrets on apoptosis of fibroblast cells and to probe its mechanism. Methods: Fibroblast cell were treated with -300, -500 and -1 000V PTFE electrets for 24, 48 and 72 h, respectively, and the influence of negative electrets on cell apoptosis was studied by means of flow cytometry and transmission electron microscope. Results: Compared with control group, apoptosis cells increased from 0.5% to 10% (some even to 15%) after 24,48 and 72 h action of -300, -500 and -1 000 V electrets. After action of -500 V PTFE electrets for 48-72 h, fibroblast cells showed characteristic morphological features of apoptosis. These features included chromatin aggregation, nuclear and cytoplasmic condensation and partition of cytoplasm and nucleus into membrane bound-vesicles (apoptotic bodies). The effect of negative electrets on apoptosis was in proportion to the time and electric field intensity. Conclusion: Negative electrets can enhance apoptosis of fibroblast cells.

Objective To explore the feasibility and superiority of the simplified partial pressurized tourniquet used in bleeding or injured limbs in battlefield.Methods The tourniquet was composed of the disposable infusion bag,bulb for blood pressure apparatus,pressure gauge and heparin cap.The disposable infusion bag wrapped around the bottom of the cravat took the places of the balloon and the harness.The pressure on the upper and lower limbs were 180mmHg and 200mmHg respectively.Results The low-cost tourniquet,with easily adjustable pressure,was easy to operate and carry.It was efficient in hemostasis and had a low rate for complications.Conclusion The tourniquet can be applied to self and buddy aid,and thus the incidence of shock can be decreased.

OBJECTIVE To investigate the clinical efficacy of pramipexole combined with levodopa-benserazide in the treatment of Parkinson’s disease (PD). METHODS A total of 108 PD patients treated at the Fifth People’s Hospital of Wuhu City from January 1, 2021, to February 28, 2023, were randomly divided into observation group and control group, with 54 cases in each group. Patients in the control group were administered levodopa-benserazide (initial dose of 62.5 mg per dose), three times daily; after one month, the dose was increased to 250 mg per dose, four times daily. Patients in the observation group received the same treatment as the control group, with the addition of pramipexole (initial dose of 0.25 mg per dose) orally twice daily on an empty stomach; after 14 days, the dose was increased to 0.25 mg per dose, three times daily. Both groups were treated for 3 months. The short-term efficacy, safety and long-term prognosis of the two groups were compared. RESULTS After treatment, the observation group had significantly lower scores on the Unified Parkinson’s Disease Rating Scale part Ⅲ (UPDRS-Ⅲ), the Hamilton Depression Scale (HAMD), the Hamilton Anxiety Scale (HAMA), and the Parkinson’s Disease Questionnaire-39( PDQ- 39) compared to the control group; in contrast, the observation group had higher scores on the Montreal Cognitive Assessment (MoCA) scale, the Mini-mental State Examination (MMSE) scale, the Mattis Dementia Rating Scale (DRS), and the Quality of Life (QOL) scale (P<0.05). Both groups showed a significant reduction in UPDRS-Ⅲ and PDQ-39 scores, and a significant increase in DRS scores compared to baseline (P<0.05). However, only the observation group showed a significant increase in MoCA scale, MMSE scale, and QOL scores, and a significant decrease in HAMD and HAMA scores compared to baseline (P< 0.05). The total incidence of adverse drug reactions in both groups was not significantly different (P>0.05). The 12 months follow-up results showed that the incidence of dementia and mortality rates in the observation group were significantly lower than the control group (P<0.05). CONCLUSIONS Pramipexole combined with levodopa-benserazide significantly improves motor function, cognitive function, quality of life and symptoms of depression and anxiety in PD patients, and may reduce the long-term risk of dementia and mortality in these patients.
