Objective To evaluate the efficiency of microsurgical methods for treatment of hypothalamic gliomas in children and the management of postoperative complications Methods Twenty-one tumors were classified into two types according to their location, size and extensive direction The tumors were removed with microsurgical technique by various approaches, such as transcallosal-interforniceal or translongitudinal fissure, transubfrontal methods Results Twenty-one cases of hypothalamic gliomas were verified by surgery and pathology The total and subtotal removal was 18 cases Partial removal was 3 cases There was no mortality in this series Major neurological complications included diabetes insipidus, electrolyte disorder and hyperthermia Surgical complications included subdural fluid collections, hydrocephalus, epilepsy Seventeen cases were followed up, and showed satisfying results Conclusion Microsurgical operations through appropriate approaches and reasonable management of complications are important methods for improving the outcome of hypothalamic gliomas in children

Objective To study the relationship between intrarenal arterial lesions(IAL)and carotid atherosclerosis(AS)in patients with renal glomerular disease.Methods 251 cases with IAL were selected and 129 age-,pressure-and eGFR-matched renal glomerular disease cases without IAL were randomly selected.The carotid intima-media thickness(IMT)was detected.Clinical and laboratory examination and renal histological characteristics were compared the two guoups.Results ①The detection rate of carotid AS was higher in patients with IAL than those without IAL(38.2%vs.20.2%),and higher in patients≥40 years than in patients＜40 years(51.3%vs.13.1%)(P<0.05 for each). ②The carotid AS group was older and had higher frequencey of fasting blood glucose,body mass index,smoking,and family history of hypertension,longer duration of established hypertension and renal glomerular disease,higher prevalence of hypertension,IAL and renal lesions,and had lower eGFR than the carotid normal group(all P＜0.05).Binary logistic regression analysis revealed that IAL and age emerged as an independent risk factor for carotid AS(OR=1.826 and 1.129,P=0.001 and 0.003).Conclusion The intrarenal arterial lesion is an independent risk factor for carotid atherosclerosis in patients with renal glomerular disease.Controlling blood glucose,blood pressure,weight,smoking quit and delaying progression of kidney disease have important significance in relieving or preventing atherosclerosis and intrarenal arterial lesions of patients with renal glomerular diseases.

[Objective] The present study aimed to determine the protective role of Melatonin (MT) against Acrylamide (AA)-induced testicular toxicity and the potential molecular mechanism.[Methods] The animals were randomly divided into three groups,the control group (n =12),the AA group (n =12) and the AA+MT group (n =12).The rats in the AA and AA + MT group were gavaged with AA at a dose of 15 mg/(kg · day) for 4 consecutive weeks.After 3 weeks of AA treatment,MT was intraperitoneally injected 30 minutes before AA treatment at 10 mg/(kg· day) for 1 week in the AA + MT rats.Subsequently,the mitochondrial membrane potential measurement,TUNEL assay,Western blot and electron microscopic techniques were applied in the present study.[Results] The results showed that AA could decrease the testis mitochondrial membrane potential (P ＜ 0.05) which could be recovered by MT (P ＜ 0.05).Moreover,MT induced down-regulation of Bax expression and up-regulation of Bcl-2 expression in the testis,compared with AA rats.The amelioration of testicular apoptosis was further confirmed by the TUNEL labeling.Western blot results suggested that the decreased ratios of Bcl-2/Bax and Bcl-xL/Bak in the AA group (both P ＜ 0.05) could be recovered by MT treatment (both P ＜ 0.05).The levels of Cyt-c,Casp-3,p53 and NF-κB in AA group were markedly elevated compared with the control (all P ＜ 0.05),and reduced in MT treatment group (all P ＜ 0.05).MT could relieve abnormal mitochondrial structures in the seminiferous tubule in the electron microscopic level.[Conclusion] MT may exert productive effect through its anti-apoptotic properties associated with mitochondria.

Purpose: Nurses play an important role in ensuring patient rehabilitation and are involved in all aspects of multidimensional rehabilitation.Therefore, strengthening rehabilitation nursing education is vital to ascertain high-quality rehabilitation and optimum outcomes. This study examined the effectiveness of a new teaching reform—a modified Six-Sigma-based training program—against a conventional educational program on rehabilitation specialist nurses’ core competencies, post-training performance, and satisfaction. Methods: A quasi-randomized controlled trial was conducted to assess the effectiveness of the modified training program. We recruited 56 learners from the 2020 training course at the Hunan Rehabilitation Specialist Nurse Training Base as the control group. Sixty learners from the base’s 2021 training course were recruited as the intervention group. Data were collected in a consistent manner from both groups after the training program was implemented. Results: Those who underwent the modified training program showed better improvement in all core competencies than those who underwent the conventional training program (p < .05); the scores for theoretical knowledge, clinical nursing lectures, reviews, and nursing case management improved significantly following the teaching reform (p < 0.05). Further, overall satisfaction as well as base management and theoretical teaching satisfaction improved significantly (p < .05). Conclusion The modified training program strengthens rehabilitation nurses’ base management abilities; enhances their core competencies; expands their interest in and breadth, depth, and practicability of theoretical courses; and updates the teaching methods.

In this paper, the domestic and international demand and development trend of clinical diagnostic radionuclides are analyzed, and the medium and high-energy cyclotrons, adequate and systematic facilities, and preparation techniques required for the production of medical radionuclides based on solid targets are introduced. This paper focuses on the research and development carried out by some important medical institutions and scientific research institutes in China over the years in the aspects of medium and high-energy cyclotrons, beam transmission lines, high-power irradiation target stations and new medical isotope production processes etc. It also looks forward to some new directions for the development of medical radionuclides in China during the 14th Five-Year Plan period.
