Objective:To investigate the computed tomography (CT) imaging features of patients with chronic hydrocephalus after intracerebral hemorrhage surgery and the difference between endoscopic third ventriculostomy (ETV) and ventricular peritoneal shunt (VPS).Methods:A total of 158 patients with intracerebral hemorrhage who received surgical treatment in the Department of Neurosurgery of the People′s Hospital of Jinan from January 2021 to June 2023 were retrospectively selected as the study objects, including 78 patients with chronic hydrocephalus after surgery as the hydrocephalus group, and 80 patients with no hydrocephalus after surgery as the non-hydrocephalus group, and the CT imaging data of the patients were statistically analyzed. Hydrocephalus group was divided into ETV group (42 cases) and VPS group (36 cases) according to different treatment methods. The efficacy and quality of life of the two groups were compared, and the incidence of complications in the two groups were counted.Results:There was no significant difference between hydrocephalus group and non-hydrocephalus group in the site of cerebral hemorrhage, hematoma morphology and the proportion of patients with mixed signs, lobular signs and black hole signs (all P>0.05). The proportion of patients with ventricular dilation and hematoma enlargement in hydrocephalus group was significantly higher than that in non-hydrocephalus group (all P<0.05). The National Institute of Health Stroke Scale (NIHSS) scores of hydrocephalus patients in the two groups were measured continuously at different time points, and there was no significant difference in NIHSS scores between the ETV group and the VPS group before treatment, at 2 weeks and 4 weeks of treatment (all P>0.05). There was no significant difference between the ETV group and the VPS group ( P>0.05). The recurrence rate of the ETV group was lower than that of the VPS group ( P<0.05). The quality of life scores of patients in ETV group were higher than those in the VPS group at 3 months and 6 months after surgery ( P<0.05). Conclusions:CT examination of patients with chronic hydrocephalus after intracerebral hemorrhage will show obvious characteristics of hematoma enlargement and ventricle enlargement. The efficacy of ETV and VPS in the treatment of chronic hydrocephalus after intracerebral hemorrhage surgery is similar, but the former has a lower recurrence rate and a higher postoperative quality of life.

Objective:To explore the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in ruptured anterior communicating wide-necked aneurysms.Methods:Thirty-two patients with ruptured anterior communicating wide-necked aneurysms accepted Neuroform Atlas stent assisted coil embolization in Department of Neurosurgery, People's Hospital Affiliated to Shandong First Medical University from January 2022 to June 2023 were chosen. DSA was performed immediately after surgery, and aneurysm embolization was assessed using Raymond grading. Prognoses were assessed by modified Rankin Scale (mRS, mRS scores≤2 as good prognosis and mRS scores>2 as poor prognosis) at last follow-up. DSA was performed again 6 months after surgery to assess the aneurysm healingResults:Neuroform Atlas stents were successfully implanted in all 32 patients; Postoperative DSA showed that aneurysm embolization reached Raymond grading I in all 32 patients(100%). No such complications as in-stent thrombosis, cerebral vasospasm, or poor opening of the stent were noted excepted for one with intraoperative aneurysm rupture hemorrhage. At the last follow-up, 31 patients had good prognosis and 1 had poor prognosis; in 22 patients underwent DSA re-examination, Raymond grading I was noted in 20 patients (90.91%) and grading II in 2 (9.09%).Conclusion:Neuroform Atlas stent-assisted coil embolization for ruptured anterior communicating wide-necked aneurysms seems safe and effective.

Objective:To analyze the disease burden of Parkinson's disease (PD) in China from 1990 to 2021 and predict the disease burden of PD from 2022 to 2030.Methods:Based on the data of PD incidence in China from the Global Burden of Disease Study 2021 (GBD 2021), changes in PD disease burden from 1990 to 2021 were analyzed. Age-period-cohort model was used to analyze the independent influences of age, period and cohort in PD incidence (according to age group of 5 years, patients were divided into 15 groups: group of 20-24 years, group of 25-29 years..., and group of 90-94 years; according to a 5-year period, patients were divided into 6 groups: group of 1992-1996, group of 1997-2001..., and group of 2017-2021; because of birth cohort=period-age, patients were divided into 20 birth cohorts: birth cohort of 1897-1906, birth cohort of 1902-1911..., and birth cohort of 1992-2001). Nordpred model was used to predict the disease burden of PD from 2022 to 2030.Results:(1) From 1990 to 2021, number of PD patients, and PD incidence and standardized incidence in China showed upward trends. The standardized incidence increased by 89.68% for the total population, 89.71% for males, and 77.64% for females. (2) PD incidence was low in young subjects and increased obviously in subjects aged 60 years. PD incidence in subjects aged 20-24 years or 90-94 years was 0.07/100 000 and 643.31/100 000, respectively. Compared with female subjects, male subjects aged 60-94 years had higher PD incidence. (3) The onset relative risk increased from 0.71 (95% CI: 0.69-0.73) in group of 1992-1996 to 1.17 (95% CI: 1.16-1.19) in group of 2017-2021 in the total population, increased from 0.68 (95% CI: 0.66-0.70) to 1.18 (95% CI: 1.16-1.21) in males, and increased from 0.75 (95% CI: 0.73-0.77) to 1.14 (95% CI: 1.12-1.16) in females. (4) Onset relative risk was 0.40 (95% CI: 0.33-0.48) in the earliest birth cohort (1897-1906), which increased to 1.81 (95% CI: 0.95-3.43) in the latest birth cohort (1992-2001). (5) Number of PD patients in males, females and total population in China would increase to 455 010, 301 173 and 756 183, respectively, and the standardized incidence would increase to 56.45/100 000, 32.28/100 000 and 43.40/100 000, respectively, till 2030. Conclusion:PD disease burden in China from 1990 to 2021 is severe, particularly among males and the elderly; the disease burden is projected to continue rising up till 2030.

A 19-year-old female patient received risperidone 3 mg twice daily for schizophrenia. She did not have nipple discharge before taking the drug. After taking the drug, nipple discharge occurred intermittently. One year later, a mass with pain in the right breast was found, which could not be alleviated after treatments with Rupi Sanjie capsules (乳癖散结胶囊), cefdinir, ibuprofen, rifampicin, and isoniazid and continued to increase, accompanied by bilateral knee pain, nodular erythema and tenderness of lower limbs. Laboratory tests showed white blood cell count 18.4×10 9/L and serum prolactin 37.42 μg/L. Ultrasonography of the right breast showed a 13.2 cm×11.0 cm×3.0 cm area low echo with unclear boundary, local fluidity, and abundant blood flow signals around. Granulomatous lobular mastitis of right breast (abscess stage) and hyperprolactiemia was diagnosed. After excluding physiological and pathological reasons, it was considered that risperidone caused hyperprolactinemia, which then induced granulomatous mastitis. However, risperidone could not be stopped without the guidance of a specialist, so only abscess incision, drainage, debridement, anti-infection, and anti-inflammatory were given. Purulent secretions gradually decreased, pain alleviated, and erythema of lower limbs partially subsided. Then risperidone dose was adjusted to 2 mg twice daily under the guidance of her psychiatrist. The serum prolactin level decreased (28.36 μg/L). At 1 year of follow-up, granulomatous mastitis did not recur.

Objective:To investigate the effect and mechanism of bone marrow mesenchymal stem cell (BMSC)-derived exosomal microRNA-1297 (miR-1297) on hippocampal neuron damage in depressed rats.Methods:BMSCs and BMSCs-derived exosomes were prepared and identified. Rats were first injected with corticosterone to establish the model of depression, and then injected with BMSCs-derived exosomes. Superoxide dismutase (SOD), malondialdehyde (MDA), lactate dehydrogenase (LDH), TNF-α and IL-1β in rat serum samples, hippocampal tissues and neurons were detected. Expression of miR-1297 in hippocampal tissues and neurons was detected by RT-qPCR. A rat hippocampal neuron injury model was established to investigate the role of BMSC-derived exosomes and miR-1297 in neuronal apoptosis and proliferation. The targeting relationship between miR-1297 and connective tissue growth factor (CTGF) was analyzed using dual luciferase reporter genes.Results:In the hippocampus of depressed rats, the expression of miR-1297 was low, while the expression of CTGF was elevated. Exosomes derived from BMSCs can inhibit the expression of CTGF by up-regulating the level of miR-1297, thereby inhibiting neuronal cell apoptosis in the hippocampus of depressed rats, while increasing the level of SOD, and reducing inflammatory damage, and ultimately improving the behavioral function of depressed rats.Conclusions:Depressed rats showed decreased expression of miR-1297 and increased expression of CTGF. BMSC-derived exosomes inhibited CTGF expression through up-regulating miR-1297, thereby improving hippocampal neuron damage in rats with depression.

OBJECTIVETo construct a personalized full-length fully human antibody mammalian display library for children with systemic lupus erythematosus (SLE).

METHODSThe total RNA was isolated from the PBMCs of SLE children. The heavy chain variable region and kappa light chain (VH and LCκ) of the antibody genes were amplified by RT-PCR and inserted into the pDGB-HC-TM vector separately to construct the heavy chain and light chain libraries. The library DNAs were transfected into 293T cells and the expression of full-length fully human antibody on the surface of 293T cells was analyzed by flow cytometry.

RESULTSUsing 0.8 µg total RNA as the template, the VH and LCκ were amplified and the full-length fully human antibody mammalian display library was constructed. The VH and LCκ gene libraries had a size of 9.4×10(4) and 8.4×10(4), respectively. Sequence analysis of 10 clones randomly selected from the VH and LCκ gene libraries each showed that 8 heavy chain clones and 7 light chain clones contained correct open reading frames, and flow cytometry demonstrated that all the 15 clones express full-length antibodies on 293T cell surfaces. 293T cells co-transfected with the VH and LCκ gene libraries expressed the full-length antibodies on the cell surface.

CONCLUSIONThe personalized full-length fully human antibody library for SLE children constructed allows display of the full-length antibodies on mammalian cell surfaces, thus providing a valuable platform for analyzing the autoantibodies, their etiological role, and their clinical implications in SLE.
