OBJECTIVE: To explore the effectiveness of primary interventional revascularization combined with secondary perforator composite flap in the treatment of peripheral arterial disease (PAD) accompanied by soft tissue defects around the ankle. METHODS: Between January 2022 and January 2025, 12 patients with PAD and soft tissue defects around the ankle were admitted. Among them, there were 9 males and 3 females; their ages ranged from 52 to 82 years, with an average of 68.9 years. The causes of injury included 4 cases of traffic accident, 5 cases of falls, 1 case of falling from height, 1 case of foreign body puncture injury, and 1 case of electric shock injury. The infection duration ranged from 1 month to 35 years, with a median duration of 3.5 months. The wound size ranged from 5.5 cm×3.0 cm to 15.0 cm×9.0 cm. The ankle-brachial index (ABI) was 0.32±0.12. The visual analogue scale (VAS) score for pain was 3.3±0.5. Preoperative vascular stenosis assessment was performed in all patients, with primary intervention to dredge large and medium-sized arteries, followed by secondary repair of the wound using a perforator composite flap. The flap size ranged from 6.5 cm×4.0 cm to 16.0 cm×10.0 cm. The donor sites were sutured directly or repaired with skin grafts. After two stages of treatment, the effectiveness was evaluated by measuring ABI, observing flap survival and wound healing, assessing VAS scores, and American Orthopedic Foot and Ankle Society (AOFAS) scores. RESULTS: All 12 cases completed two stages of treatment; all patients were followed up after the second-stage treatment, with a follow-up period ranging from 7 to 28 months, with an average of 16.8 months. After the first-stage treatment, the skin temperature around the ankle was significantly higher than that before treatment, and the ABI increased to 0.71±0.07, with a significant difference ( t=9.918, P<0.001). After the second-stage treatment, the blisters on the distal end of the skin flap occurred in 3 cases. The flaps survived and the wounds healed, with a healing time ranging from 10 to 14 days (mean, 11.8 days). The incisions at the donor site healed by first intention, and the skin grafts survived. The VAS score was 0.5±0.5 at 3 weeks, which was significantly lower than that before treatment ( t=13.675, P<0.001). No infection recurrence occurred during follow-up. At 6 months after the second-stage treatment, the AOFAS score of the ankle joint ranged from 92 to 97, with an average of 94.7, all reaching excellent. CONCLUSION Interventional revascularization combined with perforator composite flap for staged treatment of PAD with ankle soft tissue defects can obtain good effectiveness, by unclogging the main blood vessels, improving lower limb blood supply, and improving the survival rate of the skin flap.

OBJECTIVE To evaluate the efficacy of immune checkpoint inhibitors （ICIs） in the treatment of non-small cell lung cancer （NSCLC） with different KRAS genotypes. METHODS Retrieved from PubMed， the Cochrane Library， Web of Science， Embase， CNKI， Wanfang data and VIP， randomized controlled trials （RCTs） about ICIs alone， combined use of various ICIs or ICIs combined with traditional chemotherapy （trial group） versus traditional chemotherapy （control group） for NSCLC were collected from the inception of the databases to April 1， 2023. After screening literature， extracting data and evaluating quality， meta-analysis， sensitivity analysis and publication bias analysis were conducted by using RevMan 5.4 software. RESULTS A total of 7 RCTs involving 5 980 patients were included. The results of the meta-analysis showed that overall survival （OS） [HR＝ 0.79， 95%CI （0.72， 0.87）， P＜0.000 01] and progression-free survival （PFS） [HR＝0.63， 95%CI （0.50， 0.80）， P＝0.000 2] of trial group were significantly longer than those of control group； furthermore， the OS of KRAS mutant type [HR＝0.63， 95%CI （0.53， 0.75）， P＜0.000 01] and KRAS wild type [HR＝0.87， 95%CI （0.78， 0.98）， P＝0.02]， PFS of KRAS mutant type [HR＝ 0.58， 95%CI （0.43， 0.78）， P＝0.000 3] and KRAS wild type [HR＝0.68， 95%CI （0.47， 0.99）， P＝0.04] in the trial group were all significantly longer than in the control group. Subgroup analysis by different treatment regimens showed that the OS of KRAS mutant type patients receiving first- and second-line treatment regimens， using ICIs alone and those receiving ICIs combined with traditional chemotherapy as well as PFS of KRAS mutant type and wild type patients receiving first-line treatment regimens in the trial group were all significantly longer than in the control group （P＜0.05）. Sensitivity analysis results indicated that the findings of this study were robust. Publication bias results showed that the possibility of publication bias in this study was small. CONCLUSIONS ICIs show significant efficacy in NSCLC patients， and NSCLC patients benefit equally regardless of whether KRAS mutations occur.

Neurocritical care (NCC) is not only generally guided by principles of general intensive care, but also directed by specific goals and methods. This review summarizes the common pulmonary diseases and pathophysiology affecting NCC patients and the progress made in strategies of respiratory support in NCC. This review highlights the possible interactions and pathways that have been revealed between neurological injuries and respiratory diseases, including the catecholamine pathway, systemic inflammatory reactions, adrenergic hypersensitivity, and dopaminergic signaling. Pulmonary complications of neurocritical patients include pneumonia, neurological pulmonary edema, and respiratory distress. Specific aspects of respiratory management include prioritizing the protection of the brain, and the goal of respiratory management is to avoid inappropriate blood gas composition levels and intracranial hypertension. Compared with the traditional mode of protective mechanical ventilation with low tidal volume (Vt), high positive end-expiratory pressure (PEEP), and recruitment maneuvers, low PEEP might yield a potential benefit in closing and protecting the lung tissue. Multimodal neuromonitoring can ensure the safety of respiratory maneuvers in clinical and scientific practice. Future studies are required to develop guidelines for respiratory management in NCC.

Objective:To investigate the clinical characteristics and possible mechanisms of remote intracranial hematoma (RIH) in patients with intracranial aneurysm after interventional embolization.Methods:Six patients with RIH from a series of 58 consecutive patients with intracranial aneurysm, admitted to and performed interventional embolization in our hospital from January 2016 and December 2018, were chosen in our study. Their clinical data were analyzed retrospectively and compared with those without RIH at the same period.Results:In these 6 patients, 4 had history of hypertension, 5 had aneurysm located in the internal carotid artery, 5 were treated with stents combined with postoperative routine anticoagulation treatment. The remote intracranial hematoma occurred within 7 d of interventional embolization, and the hematoma was located in the cerebral hemisphere on the same side of the aneurysm; 4 patients underwent intracranial hematoma puncture catheter drainage; 1 patient was treated conservatively, and one was treated by craniotomy. After treatment, 1 patient recovered (modified Rankin scale [mRS] score of 1), 1 patient had poor prognosis (mRS scores of 5) and discharged automatically, and the rest 4 patients (mRS scores of 3-5) left some degrees of neurological dysfunction. As compared with 52 patients without RIH, 6 patients with RIH had significantly higher percentages of patients used stents and postoperatively used anticoagulation, and higher percentages of patients with poor clinical outcomes at discharge ( P<0.05). Conclusion:Stent-assisted coil embolization in patients with internal carotid artery aneurysm combined with hypertension should be highly vigilant about the possibility of RIH.

Objective:To explore the influence of multidimensional integration and 360° support on the function of family and marriage, and quality of life in women patients with systemic lupus erythematosus.Methods:Totally 196 patients with systemic lupus erythematosus from Department of Rheumatology and Immunology, The Second Affiliated Hospital of the Air Force Medical University from August 2016 to November 2017 were included. According to random number table method, these patients were divided into observation group and control group as 98 cases each. Conventional care and hospital discharge were used for control group. On the basis of this, multidimensional integration and 360° support were used for patients of observation group. The function of family and marriage, quality of life in patients were assessed before and after 3 months of the intervention. The treatment adherence was evaluated in 3 months and 6 months after intervention.Results:Before intervention, the marriage family function score, marital satisfaction, conflict resolution methods and the relationship with friends and family, husband and wife exchange scores of the observation group were (2.3 ± 0.5), (24.6 ± 6.1), (25.7 ± 7.1), (28.2 ± 6.9), (28.8 ± 6.9) points, respectively. Three months after intervention, these scores were (2.5 ± 0.7), (31.6 ± 5.0), (31.7 ± 5.3), (28.1 ± 6.8), (29.0 ± 7.1) points, respectively. There was statistically significant difference between before and after the intervention ( t values were -2.371 - 8.631, P < 0.01). These scores of control group before the intervention were (2.3 ± 0.6), (24.5 ± 6.2), (25.2 ± 7.2), (32.5 ± 6.0), (33.9 ± 6.3) points, respectively. Three months after intervention, these scores were (2.3 ± 0.4), (24.5 ± 6.2), (26.1 ± 6.9), (29.1± 4.8), (28.5 ± 7.2) points. Significant differeces were found between before and after the intervention in control group ( t values were -3.878-6.323, P < 0.05 or 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 2.675-8.631, P<0.01). As for observation group, planning (62.8 ± 27.2 vs. 75.5 ± 25.4) and intimate relationship (62.8 ± 25.2 vs. 78.2± 24.9) in quality of life were obviously difference before and after 3 months of intervention ( t values were 3.050, 3.639, P < 0.01). As for control group, planning (62.5 ± 27.6 vs. 65.7 ± 24.9) and intimate relationship (65.8 ±25.2 vs. 63.5 ± 23.8) in quality of life were obviously difference before and after 3 months of intervention ( t values were 2.375, 3.132, P < 0.01). There was statistically significant difference between the two groups after the intervention ( t values were 3.050, 3.639, P < 0.01). The treatment adherence of observation group was significant better than control group. After 6 months intervention, the treatment adherece of observation group was 83.67% (82/98), while the treatment adherece of control group was 44.89% (44/98), significant differences were found btween the two groups ( χ2 value was 0.511, P < 0.01). Conclusion:Multidimensional integration and 360° support obviously improved function of family and marriage, improved the understanding of disease, and self-management ability of patients. Therefore, it can increase the treatment adherence and improve quality of life in SLE patients.
