ObjectiveTo explore the central neuroregulation mechanism of heat-sensitive moxibustion for knee osteoarthritis on pain relief. MethodsThirty patients who did not have experience of Deqi （得气） during heat-sensitive moxibustion treatment were assigned to the "non-Deqi group"， while another 30 patients who had experience of Deqi were assigned to the "Deqi group". Both groups received moxibustion at the left Heding （EX-LE2） acupoint. In the Deqi group， after the patients experienced sensation of Deqi at the acupoint， moxibustion was applied at approximately 3 cm from the skin for 10 minutes； in the non-Deqi group， moxibustion was also applied at approximately 3 cm from the skin for 10 minutes. Both groups received treatment once daily for 10 consecutive days. Knee joint pain was assessed before and after treatment using the visual analog scale （VAS）. Resting-state functional magnetic resonance imaging （rs-fMRI） scans were performed on all participants before the first treatment session and after the final session on the 10th day. The fractional amplitude of low-frequency fluctuations （fALFF） maps before and after treatment were processed using the SPM12 module by MATLAB. ResultsAfter treatment， VAS scores in both groups were significantly lower than before treatment （P＜0.05 or P＜0.01）， with the Deqi group showing significantly lower VAS scores than the non-Deqi group （P＜0.01）. Compared to before treatment， the Deqi group exhibited significant activation in the prefrontal cortex （t = 6.28）， white matter （t = 6.36）， and left temporal lobe （t = 9.33）， while significant inhibition was observed in the occipital lobe （t = -9.86） and right cerebrum （t = -4.54， P＜0.01）； in the non-Deqi group， significant changes after treatment were observed in the left occipital lobe （t = -6.42）， left medial frontal gyrus （t = -4.35）， left middle frontal gyrus （t = -4.74）， right superior frontal gyrus （t = -4.82）， right superior temporal gyrus （t = -6.61）， and right cerebellar posterior lobe （t = -8.64）， all of which were in inhibited states （P＜0.01）. Compared to the non-Deqi group， the Deqi group exhibited significant activation after treatment in the external nucleus （t = 5.77）， white matter （t = 3.58）， right cerebrum （t = 5.84）， left cerebellum （t = 5.35）， and left cerebrum （t = 4.32）， while significant inhibition was observed in the prefrontal cortex （t = -4.16）， occipital lobe （t = -4.87）， and precentral gyrus （t = -4.46， P＜0.01）. ConclusionsHeat-sensitive moxibustion provides better analgesic effects for knee osteoarthritis under state of Deqi. Its central neuroregulation mechanism may be related to the involvement of the frontal lobe， temporal lobe， occipital lobe， external nucleus， white matter， right cerebrum， left cerebellum， left cerebrum， and precentral gyrus in modulating pain signals.

OBJECTIVES: Whether vortioxetine has a utility as an adjuvant drug in the treatment of bipolar depression remains controversial. This study aimed to validate the efficacy and safety of vortioxetine in bipolar depression. METHODS: Patients with bipolar Ⅱ depression were enrolled in this prospective, two-center, randomized, 12-week pilot trial. The main indicator for assessing treatment effectiveness was a Montgomery-Asberg Depression Rating Scale (MADRS) of ≥50%. All eligible patients initially received four weeks of lurasidone monotherapy. Patients who responded well continued to receive this kind of monotherapy. However, no-response patients were randomly assigned to either valproate or vortioxetine treatment for eight weeks. By comprehensively comparing the results of MADRS over a period of 4‍‒‍12 weeks, a systematic analysis was conducted to determine whether vortioxetine could be used as an adjuvant drug for treating bipolar depression. RESULTS: Thirty-seven patients responded to lurasidone monotherapy, and 60 patients were randomly assigned to the valproate or vortioxetine group for eight weeks. After two weeks of combined valproate or vortioxetine treatment, the MADRS score in the vortioxetine group was significantly lower than that in the valproate group. There was no difference in the MADRS scores between the two groups at 8 and 12 weeks. The incidence of side effects did not significantly differ between the valproate and vortioxetine groups. Importantly, three patients in the vortioxetine group appeared to switch to mania or hypomania. CONCLUSIONS This study suggested that lurasidone combination with vortioxetine might have potential benefits to bipolar II depression in the early stage, while disease progression should be monitored closely for the risk of switching to mania.

Objective:To evaluate the short-term safety of Nirsevimab injection for preventing respiratory syncytial virus infections in infants through a physician-nurse-pharmacist collaborative model.Methods:This prospective observational study enrolled infants receiving single-dose Nirsevimab at Peking University Third Hospital from September 2024 to August 2025. A multidisciplinary team comprising pediatricians, nurses, pharmacists, and obstetricians was established to develop standardized protocols for medication management, injection procedures, follow-up processes, and safety assessment forms. Descriptive statistics analyzed on-site observations within 30 minutes post-injection and all adverse events, with causality assessment conducted.Results:Among 331 participants [171 males (51.7%), 160 females (48.3%)], 225 (68.0%) received outpatient injections and 106 (32.0%) inpatient injections. Successful administration was achieved in 330 cases (99.7%), including 207 (62.7%) receiving 50 mg/vial and 123 (37.3%) receiving 100 mg/vial formulations; one child (3 years 11 months, 19.0 kg) received two 100 mg doses. During the 30-minute observation, 11 cases (3.3%) experienced adverse events, all presenting as injection site erythema following 100 mg/vial administration, with no systemic or serious adverse events observed. All symptoms resolved spontaneously within 30 minutes. Multidisciplinary review suggested potential associations with insufficient rewarming time, larger injection volumes, or post-injection compression pressure.Conclusion:Nirsevimab demonstrated favorable short-term safety profiles in Chinese infants following single-dose administration, with feasible multidisciplinary standardized protocols, though larger sample sizes and extended follow-up are warranted for monitoring medium-to-long-term safety and special populations.

Objective To investigate the safety and effectiveness of endovascular treatment in patients with acute ischemic stroke due to large vessel occlusion(AIS-LVO)over 24 h after onset.Methods The clinical data of AIS-LVO patients who received endovascular treatment in Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2022 were retrospectively analyzed,including baseline characteristics,imaging findings,treatment,degree of vascular recanalization(modified thrombolysis in cerebral infarction grade 2b and 3 for successful recanalization)and prognosis.Results A total of 57 patients were included,including 42 males and 15 females,aged from 30 to 84 years old.The most common risk factors were hypertension(39 cases,68.4%),followed by smoking history(24 cases,42.1%),diabetes mellitus(17 cases,29.8%),previous stroke history(16 cases,28.1%),and atrial fibrillation(9 cases,15.8%).Before treatment,the National Institutes of Health stroke scale score was 12.84±7.04,and the Alberta Stroke Program early computed tomography score was 9.00(7.00,10.00).Vascular occlusion sites included middle cerebral artery occlusion in 27(47.4%)cases,internal carotid artery occlusion in 24(42.1%)cases,and tandem lesions in 6(10.5%)cases.The time from onset to femoral artery puncture was 38.30(28.17,53.71)h,and the time from femoral artery puncture to vascular recanalization was 52.00(38.50,92.50)min.General anesthesia was the main anesthesia method,accounting for 64.9%(37/57).The etiological types of stroke were mainly large artery atherosclerosis(38 cases,66.7%),cardiogenic embolism(9 cases,15.8%),unknown causes(6 cases,10.5%),and other clear causes(4 cases,7.0%).Mechanical thrombectomy was the first choice in 41(71.9%)cases,balloon dilatation/stenting was used in 35(61.4%)cases,of which 15(26.3%)cases were the first choice.Finally,53(93.0%)cases were recanalized successfully.In terms of complications,1(1.8%)case had symptomatic intracranial hemorrhage.The 90-d prognosis rate was 59.6%(34/57),and 3(5.3%)cases died.Conclusion Endovascular treatment for AIS-LVO patients over 24 h after onset has high recanalization rate and good safety,but it still needs to be further verified by randomized controlled trials.

Objective:To investigate the effects of Zhuanggu Zhitong Capsules on JNK signaling molecules and their phosphorylated proteins in postmenopausal osteoporosis model female mice.Methods:The rats were divided into sham-operation group, blank group, model group, positive drug group, and Zhuanggu Zhitong Capsules group according to the random number table method, with 10 rats in each group. The model group, the positive drug group and the Zhuanggu Zhitong Capsules group were prepared by bilateral ovarian detomy to prepare a female mouse model of postmenopausal osteoporosis. The positive drug group was given 0.9 mg/kg of alendronate sodium, the Zhuanggu Zhitong Capsules group was given was Zhuanggu Zhitong Capsules 1.944 g/kg for gavage, and the blank group, sham-operation group, and model group were given the same volume of normal saline for gavage, once a day for a total of 13 weeks. Rat vaginal exfoliated cells were stained with Wright's staining; serum Omentin-1 and 25(OH)D 3 levels were determined by ELISA; renal tissue and femoral structure were observed by HE staining; JNK and p-JNK protein expressions were detected by immunohistochemical staining; JNK mRNA levels were detected by PCR. Results:Compared with the model group, the serum levels of 25(OH)D3 and Omentin-1 in the Zhuanggu Zhitong Capsules group and the positive drug group increased ( P<0.01), the mean gray values of JNK and p-JNK protein in bone and kidney tissues decreased ( P<0.01), and the mRNA levels of JNK in bone and kidney tissues decreased ( P<0.01). Conclusion:Zhuanggu Zhitong Capsules can effectively improve the bone microstructure of postmenopausal osteoporotic rats, and its mechanism may be related to the regulation of JNK signaling pathway.
