Objective:To compare the clinical efficacy of endoscopic posterior transforaminal lumbar interbody fusion (Endo-PTLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in the treatment of single-segment lumbar degenerative diseases.Methods:A retrospective analysis was conducted on the clinical data of 56 patients with single-segment lumbar degenerative diseases treated at Xiuzhou District People's Hospital between September 2020 and March 2023. Patients were divided into two groups based on the surgical approach: the Endo-PTLIF group (24 cases, 11 males and 13 females; mean age: 56.5±8.4 years, range: 43-72 years) and the MIS-TLIF group (32 cases, 10 males and 22 females; mean age: 54.5±10.4 years, range: 37-73 years). Perioperative parameters, visual analog scale (VAS) scores for pain, Oswestry disability index (ODI), lumbar lordosis (LL), disc height (DH), and dural sac cross-sectional area (DSCA) were compared between the two groups.Results:No significant differences were observed between the two groups in baseline characteristics, preoperative VAS, ODI, LL, DH, or DSCA ( P>0.05). However, the operative time in the Endo-PTLIF group (173.9±12.3 minutes) was significantly longer than in the MIS-TLIF group (136.5±19.5 minutes, P<0.05). Similarly, the Endo-PTLIF group required more fluoroscopy exposures (15.9±1.8) than the MIS-TLIF group (13.0±1.6, P<0.05). In contrast, intraoperative blood loss in the Endo-PTLIF group (68.9± 12.9 ml) was significantly lower than in the MIS-TLIF group (126.7±35.4 ml, P<0.05). Additionally, the Endo-PTLIF group had a shorter hospital stay [7.00 (6.25, 7.75) days] compared to the MIS-TLIF group [10.00 (9.25, 11.00) days, P<0.05]. At one week and one month postoperatively, the Endo-PTLIF group had significantly lower back pain VAS scores [2.00 (2.00, 3.00) and 2.00 (2.00, 2.00), respectively] and a lower ODI (25.83%±3.83%) compared to the MIS-TLIF group [3.00 (2.25, 4.00), 2.50 (2.00, 3.00), and 30.09%±4.02%, respectively; P<0.05]. Beyond one month postoperatively, there were no significant differences in leg pain VAS scores between the groups, and back pain VAS and ODI showed no significant differences after six months ( P>0.05). At the final follow-up, the excellent and good rates, according to MacNab criteria, were 95.8% in the Endo-PTLIF group and 93.8% in the MIS-TLIF group, with no significant difference ( P>0.05). At 12 months postoperatively, both groups showed significant improvements in LL, DH, and DSCA compared to preoperative values ( P<0.05), but there were no significant differences between the two groups ( P>0.05). The fusion rates were 96% in the Endo-PTLIF group and 94% in the MIS-TLIF group, with no significant difference ( P>0.05). Complications included one case of dural tear in the Endo-PTLIF group, and one case of dural tear and one case of incision infection in the MIS-TLIF group. Conclusion:Endo-PTLIF achieves comparable clinical efficacy to MIS-TLIF in the treatment of single-segment lumbar degenerative diseases, with the added advantages of reduced intraoperative blood loss and faster postoperative recovery.

Objective:To explore the clinical characteristics and healthcare burden in patients with McCune-Albright syndrome (MAS).Methods:A cross-sectional study was conducted at the Children′s Hospital, Zhejiang University School of Medicine. Clinical and healthcare burden data were systematically collected through structured questionnaires in 164 children with MAS from February 2022 to May 2023. According to the clinical characteristics, patients were categorized into 3 groups: monosymptomatic, bisymptomatic and trisymptomatic groups. Patients were also divided into 3 groups according to the age of <7, 7-<10 and 10-18 years. Comparative analyses of clinical characteristics and healthcare burden were conducted across age, sex, and symptom categories.Results:The cohort comprised 59 males (36.0%) and 105 females (64.0%) with an age of 4.6 (2.0, 7.4) years. Age stratification revealed 117 cases (71.3%) aged 0-<7 years, 29 cases (17.7%) aged 7-<10 years, and 18 cases (11.0%) aged 10-<18 years. Among monosymptomatic (67 cases, 40.9%), the cohort comprised 32 females (47.8%) and 35 males (52.2%), predominantly presenting with fibrous dysplasia (57 cases, 85.1%). This subgroup showed peak prevalence in the 0-<7 years age range (29 cases (50.9%)). The bisymptomatic cohort (56 cases, 34.1%) consisted of 39 females (69.6%) and 17 males (30.4%), predominantly manifesting fibrous dysplasia with skin hyperpigmentation (25 cases, 44.6%). Peak prevalence occurred in the 0-<7 years subgroup(16 cases (64.0%)). The trisymptomatic cohort (41 cases, 25.0%) consisted of 34 females (82.9%) and 7 males (17.1%), with peak prevalence occurring in the 0-<7 years subgroup (36 cases (87.8%)). The diagnostic journey analysis revealed 94 cases (57.3%) required 1-3 referrals, and 34 cases (20.7%) necessitated >3 referrals from symptom onset to definitive diagnosis. Healthcare expenditure analysis revealed 69 families (42.1%) incurred direct medical costs of 10 000-100 000 CNY, with 11 families (6.7%) exceeding >100 000 CNY. Direct non-medical costs reached of 10 000-100 000 CNY for 62 families (37.8%) and >100 000 CNY for 4 families (2.4%). Productivity loss affected 58 families (35.4%) at 10 000-100 000 CNY and 8 families (4.9%) above 100 000 CNY during the study period.Conclusion:MAS requires increased attention to skeletal manifestations, especially in children aged 0-<7 years. Moreover, the significant financial burden on families necessitates a society-wide support system.

Objective:To investigate the differences in dosimetric parameters for target volumes and organs at risk (OARs), radiation doses to reconstructed tissues, and beam-on time in radiotherapy among helical tomotherapy (HT), volumetric modulated arc therapy (VMAT), and fixed-field intensity-modulated radiotherapy (F_IMRT) following immediate breast reconstruction for breast cancer, thereby providing a reference for the selection of clinical radiotherapy techniques.Methods:This study retrospectively investigated 15 breast cancer patients who underwent radiotherapy following modified radical mastectomy and immediate breast reconstruction at the Liuzhou Worker′s Hospital from August 2018 to July 2023. During target volume delineation, precautions were taken to avoid the reconstructed tissues, which were delineated separately. Customized HT, VMAT, and F_IMRT treatment plans were designed for each patient. The plans were categorized into the HT, VMAT, and F_IMRT groups based on different radiotherapy techniques employed. They were comparatively analyzed through one-way analysis of variance (ANOVA), with multiple comparisons further conducted in the case of significant differences.Results:Statistical analyses reveal significant differences in various parameters of target volumes among the three groups of plans ( F = 38.73, 14.95, 37.01, 48.05, 35.55, 22.56, 34.30, P < 0.05). Pairwise comparisons indicate that the maximum dose ( D2%), minimum dose ( D98%), mean dose ( Dmean), and the proportion of high-dose volumes within the target volume ( V107%and V110%) in both the HT and VMAT groups were significantly better than those in the F_IMRT group. The HT group demonstrated the optimal conformity index (CI), while the VMAT group displayed the superior homogeneity index (HI) compared to the other two groups. In terms of OAR, the V20 of the ipsilateral lung was the lowest in the HT group ( F = 14.31, P < 0.05) and the highest in the F_IMRT group ( F = 14.31, P < 0.05). However, the V5 and Dmean for both the ipsilateral and contralateral lungs in the HT group significantly surpassed those of the other groups ( F = 39.16, 31.91, P < 0.05). The mean dose Dmean ( F = 5.57, P < 0.05) of the contralateral breast was significantly reduced in the VMAT group compared to the other two groups. No statistically significant differences were observed for other OARs, including the heart, spinal cord PRV, thyroid, and humeral head ( P > 0.05). The radiation doses to reconstructed tissues ( Dmax, V53.5, Dmean) ascended in the order of HT, VMAT, and F_IMRT groups ( F = 17.69, 17.53, 15.11, P < 0.05). The HT and F_IMRT groups showed similar beam-on times ( P > 0.05), both exceeding that of the VMAT group by several folds ( F = 28.72, P < 0.05). Conclusions:The comparative analysis indicates that the three radiotherapy techniques exhibit distinct advantages and limitations, with F_IMRT demonstrating the least comprehensive advantage. HT can enhance the conformity of target volumes while reducing the overall radiation doses to reconstructed tissues and the crucial indicator V20 in the ipsilateral lung. VMAT demonstrates the highest treatment efficiency, yielding improved dose uniformity in the target volume and reduced radiation doses to the contralateral breast. It is advisable to prioritize HT or VMAT based on actual clinical conditions.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results.

Cardiac arrest (CA) is a serious cardiac event, which has a high incidence and low survival rate at home and abroad. In order to predict the risk of CA in advance, a large number of studies have been conducted by relevant researchers. This paper mainly summarizes the characteristics and research status of the existing analysis and prediction of CA from three aspects: the risk prediction factors of CA, the evaluation index of risk prediction of CA and the early warning scoring system of CA. We hope it can help medical staff to understand the current progress in this field, and provide new ways and methods for predicting the risk of CA.

ObjectiveTo investigate the effect of modified Baduanjin exercise, as an rehabilitation exercise, on cardiopulmonary function, motor function and activities of daily living in patients with stroke. MethodsFrom January to September, 2023, 42 stroke patients in the Nanjing Qixia District Hospital were randomly divided into control group (n = 21) and experimental group (n = 21). The control group received routine rehabilitation, and the experimental group received modified Baduanjin exercise in addition, for four weeks. They were assessed with peak oxygen uptake (VO_2peak), anaerobic threshold (AT), peak oxygen pulse (VO_2peak/HR), forced vital capacity (FVC), forced expiratory volume in the first second (FEV₁), peak expiratory flow (PEF), Fugl-Meyer Assessment-upper extremities (FMA-UE), Berg Balance Scale (BBS) and modified Barthel Index (MBI) before and after intervention. ResultsVO_2peak, AT, and the scores of FMA-UE, BBS and MBI improved in the control group after intervention (|t| > 2.256, |Z| > 2.936, P < 0.05); while VO_2peak, AT, VO_2peak/HR, FVC, FEV₁, PEF, and the scores of FMA-UE, BBS and MBI improved in the experimental group (|t| > 4.390, |Z| > 3.451, P < 0.001); and all the indexes were better in the experimental group than in the control group (|t| > 4.136，|Z| > 2.751，P < 0.01), except the scores of BBS and MBI. ConclusionModified Baduanjin exercise can improve the cardiopulmonary function and upper limb motor function for stroke patients.
