This paper summarizes professor YANG Chunbo's clinical experience in treating refractory constipation （RC） complicated with melanosis coli （MC） from the perspective of damp-heat theory. Internal accumulation of damp-heat is considered as the core pathogenesis of this condition， and the therapeutic principles should focus on clearing， transforming， tonifying， and resolving. Self-formulated Qinghua Beverage （清化饮） is developed to clear and transform damp-heat， regulate qi， and soothe collaterals. In clinical practice， RC complicated with MC is classified into damp-heat with qi stagnation syndrome and damp-heat with stasis obstruction syndrome. Qinghua Beverage is used as the base prescription with modifications according to syndrome differentiation. For damp-heat with qi stagnation syndrome， medicinals that promote qi movement and unblock the bowels， activate blood and clear collaterals are added， while for damp-heat with stasis obstruction syndrome， herbs that resolve stasis and unblock collaterals are incorporated， with simultaneous consideration of nourishing blood and supporting collaterals.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Diagnosis and treatment of refractory hydrocephalus are the keys in reflecting the overall level of diagnosis and treatment of hydrocephalus. However, there is currently no clear definition of refractory hydrocephalus; moreover, treatment of these patients is difficult, with high failure rate. This article focuses on the definition, common causes and classification of refractory hydrocephalus, the treatment strategies of infectious refractory hydrocephalus, the treatment dilemmas of negative pressure or low-pressure hydrocephalus, and treatment future directions of refractory hydrocephalus, in order to attract attention of clinicians to the diagnosis and treatment of refractory hydrocephalus.

Objective:To summarize the clinical and genetic characteristics of late-onset facioscapulohumeral muscular dystrophy type 1 (FSHD1) patients, and to compare the differences between late-onset and classic-onset FSHD1 patients.Methods:A retrospective analysis was conducted on the clinical and genetic data of genetically confirmed late-onset FSHD1 patients (age at onset30 years) between January 2007 and June 2024 from the Department of Neurology of Peking University First Hospital and the First Affiliated Hospital of Fujian Medical University. Classic-onset FSHD1 patients (10 yearsage at onset≤30 years) were matched 1∶1 according to sex and disease duration for comparison. The demographic information, the number of D4Z4 repeat units, the distal D4Z4 methylation levels, FSHD Clinical Score (CS), Clinical Severity Score (CSS), and Age-Corrected Clinical Severity Score (ACSS) of these patients were collected. Survival analysis was performed to compare the outcome of lower extremity involvement between late-onset and classic-onset FSHD1 patients. The correlation of the number of D4Z4 repeat units and D4Z4 methylation level with CS and ACSS was analyzed in late-onset FSHD1 patients.Results:A total of 61 patients with late-onset FSHD1 were enrolled, 33 (54.1%) of whom are female, with an age of 54.0 (46.0, 62.0) years and a disease duration of 14.0 (5.5, 22.5) years. Compared to classic-onset FSHD1 patients, late-onset patients exhibited significantly lower CS [7.0 (5.6, 8.4) vs 6.0 (4.4, 7.7), U=1 416.000, P=0.013], CSS [3.0 (2.8, 3.3) vs 3.0 (2.0, 4.0), U=2 352.000, P=0.010], and ACSS [189.2 (137.1, 241.3) vs 96.8 (61.3, 132.2), U=3 225.500, P0.001], and higher proportion of patients with limb girdle involvement but no facial muscle involvement [18.0% (11/61) vs 6.6% (4/61), χ2=3.725, P=0.054]. Kaplan-Meier survival analysis showed that the onset age of lower extremity involvement in late-onset patients (45 years, 95% CI 42-48 years) was significantly higher than that in classic-onset patients (24 years, 95% CI 21-27 years, χ2=61.012, P0.001). The duration from symptom onset to lower extremity involvement in late-onset patients (15 years, 95% CI 10-20 years) was significantly longer than that in classic-onset patients (8 years, 95% CI 3-13 years, χ2=9.105, P=0.003). Late-onset FSHD1 patients carried higher average distal D4Z4 methylation levels compared to those with classic-onset FSHD1 [46.68% (40.79%,52.57%) vs 41.02% (34.03%,48.00%), U=1 378.500, P=0.014]. Among late-onset FSHD1 patients, cytosine-phosphate-guanine 6 (CpG6) methylation levels were significantly negatively correlated with ACSS ( r=-0.278, P=0.025); the number of D4Z4 repeat units were significantly negatively correlated with ACSS ( r=-0.272, P=0.034);CpG6 methylation levels were significantly negatively correlated with CS ( r=-0.441, P=0.003), while no correlation was found between number of D4Z4 repeat units and CS ( r=-0.161, P=0.310). Conclusions:Compared with classic-onset FSHD1 patients, late-onset FSHD1 patients are associated with a higher degree of distal D4Z4 methylation, along with a milder muscle weakness phenotype, slower disease progression and a higher proportion of cases without facial muscle involvement. The age at onset can be used as a marker of the severity and prognosis in FSHD1.

Objective:To investigate the effectiveness of gastric-soleal turndown flap and knotless anchor bridging fixation via a modified incision in the treatment of chronic Achilles tendon rupture of Myerson type Ⅲ.Methods:A retrospective case series study was conducted to analyze the clinical data of the 18 patients who had been treated at Department of Minimally Invasive Orthopedics, Zhengzhou Orthopaedic Hospital from February 2020 to July 2023 for chronic Achilles tendon rupture of Myerson type Ⅲ by means of gastric-soleal turndown flap and knotless anchor bridging fixation via a modified incision. There were 15 males and 3 females, with an age of (37.2±6.8) years. All patients suffered from unilateral injury, involving 13 left sides and 5 right sides. Their body mass index was (22.6±2.5) kg/m 2. The operation time, blood loss, incision length, wound healing and complications were documented. The ankle dorsiflexion and plantar flexion at the last follow-up were compared between the affected side and the healthy side. The American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and Achilles tendon total rupture score (ATRS) before operation were compared with those at the last follow-up. Results:All the 18 patients were followed up for (18.0±5.5) months. Their operation time was (69.1±5.2) minutes, blood loss (71.6±9.2) mL, incision at the broken end of the Achilles tendon (12.4±2.6) cm and incision at the proximal end (2.5±0.4) cm. At the last follow-up, the ankle dorsiflexion was 12.7°±1.9° and the ankle plantar flexion 35.2°±2.0° at the affected side, showing no significant difference from those at the healthy side (13.0°±2.1° and 34.7°±1.8°) ( P>0.05). The AOFAS ankle-hindfoot score was (89.4±3.4) points and the ATRS (85.3±3.2) points for the affected side at the last follow-up, showing significant improvements compared with the preoperative values [(54.2±4.2) points and (51.1±4.6) points] ( P<0.05). All the incisions healed at one stage after operation, with no such complications as incision infection or re-rupture of the Achilles tendon. One patient experienced mild pain at the anchor insertion site, but the pain disappeared 6 months after operation without any treatment. One patient had the symptoms of sural nerve injury which responded to 3 months of oral neurotrophic medication. Conclusion:In the treatment of chronic Achilles tendon rupture of Myerson type Ⅲ, gastric-soleal turndown flap and knotless anchor bridging fixation via a modified incision can result in limited invasion, a low incidence of complications, and definite effectiveness.

Objective:To analyze and compare the reporting data of adverse events following immunization (AEFI) of influenza vaccines in Fujian Province from 2019 to 2023.Methods:Using the National Immunization Program Information Management System, the AEFI reports and vaccination data of influenza vaccines in Fujian Province from 2019 to 2023 were collected, and the reporting rates and clinical characteristics of AEFI of 6 types of influenza vaccines were compared. The 6 types of vaccines in the analysis were as follows: trivalent inactivated influenza vaccines (IIV3) for 6-35 months old people, IIV3 for ≥3 years old people, trivalent live attenuated nasal spray vaccine (LAIV3) for 3-17 years old people, quadrivalent inactivated influenza vaccines (IIV4) for 6-35 months old people, IIV4 for ≥6 months old people, and IIV4 for ≥3 years old people.Results:From 2019 to 2023, a total of 87 687.21 million doses of influenza vaccine were vaccinated in Fujian Province, and 510 cases of AEFI were reported, with a reporting rates of 5.82 per 100 000 doses. Among the 510 cases, 443 (86.86%) were general reactions, 56 (10.98%) were abnormal reactions, 1 (0.20%) was psychogenic reactions, and 10 (1.96%) were coincidence. There were no reports of vaccination accidents and vaccine quality accidents. The reporting rates of AEFI were relatively higher in 2019 and 2020 (18.38 and 18.00 per 100 000 doses, respectively), and lower in 2021, 2022 and 2023 (8.91, 10.68 and 2.30 per 100 000 doses, respectively); the differences were statistically significant (all P<0.05). The differences of reporting rates of AEFI between IIV3 for 6-35 months old people and IIV4 for 6-35 months old people, the injectable vaccines and nasal spray vaccines were not statistically significant. However, the reporting rates of overall AEFI, general reactions and abnormal reactions of IIV3 for ≥3 years old people were all higher than those of IIV4 for ≥3 years old people (7.77 per 100 000 doses vs. 3.88 per 100 000 doses, 6.18 per 100 000 doses vs. 3.59 per 100 000 doses, 1.41 per 100 000 doses vs. 0.19 per 100 000 doses). The reporting rates of overall AEFI and general reaction of IIV3 for 6-35 months old people were both higher than those of IIV3 for ≥3 years old (16.47 per 100 000 doses vs. 7.77 per 100 000 doses, 13.05 per 100 000 doses vs. 6.18 per 100 000 doses), and the differences were statistially significant (all P<0.05). The reporting rates of general abnormal reactions of IIV4 for 6-35 months old and ≥ 6 months old people were both higher than those of IIV4 for ≥3 years old people (14.73 per 100 000 doses and 9.52 per 100 000 doses vs. 3.88 per 100 000 doses); the reporting rates of general reactions and abnormal reactions of IIV4 for ≥6 months old people were both higher than those of IIV4 for ≥3 years old people (12.94 per 100 000 doses vs. 3.59 per 100 000 doses, 1.34 per 100 000 doses vs. 0.19 per 100 000 doses), the differences were statistcially significant (all P<0.05). In terms of clinical features, the reporting rates of fever (37.6-38.5 ℃ and ≥ 38.5 ℃), local redness and swelling (diameter 2.6-5.0 cm), and local induration (diameter ≤2.5 cm and 2.6-5.0 cm) after vaccination of IIV3 for ≥3 years old people were higher than those of IIV4 for ≥ 3 years old people (1.41 per 100 000 doses vs. 0.64 per 100 000 doses, 3.00 per 100 000 doses vs. 1.16 per 100 000 doses); the reporting rates of allergic rash and angioedema of IIV3 for ≥ 3 years old people were higher than those of IIV4 for ≥3 years old people (0.53 per 100 000 doses vs. 0.12 per 100 000 doses, 0.35 per 100 000 doses vs. 0); the differences were statistically significant (all P<0.016 7). Conclusions:The reporting rates of AEFI for influenza vaccines in Fujian Province from 2019 to 2023 was showing a downward trend. The AEFI was mainly general reactions. The reporting rates of AEFI were different among different influenza vaccines, but the overall safety was good.
