OBJECTIVES: To study the correlation of the expression of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue with hepatic fat content in rats with intrauterine growth retardation (IUGR). METHODS: Pregnant rats were given a low-protein (10% protein) diet during pregnancy to establish a model of IUGR in neonatal rats. The pregnant rats in the control group were given a normal-protein (21% protein) diet during pregnancy. The neonatal rats were weighed and liver tissue was collected on day 1 and at weeks 3, 8, and 12 after birth, and visceral adipose tissue was collected at weeks 3, 8, and 12 after birth. The 3.0T ¹H-magnetic resonance spectroscopy was used to measure hepatic fat content at weeks 3, 8, and 12 after birth. Real-time PCR was used to measure mRNA expression levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. Western blot was used to measure protein levels of Lipin2 in liver tissue and Lipin1 in visceral adipose tissue. A Pearson correlation analysis was performed to investigate the correlation of mRNA and protein expression of Lipin with hepatic fat content. RESULTS: The IUGR group had significantly higher mRNA and protein expression levels of Lipin1 in visceral adipose tissue than the control group at weeks 3, 8, and 12 after birth (P<0.05). Compared with the control group, the IUGR group had significantly lower mRNA and protein expression levels of Lipin2 in liver tissue on day 1 after birth and significantly higher mRNA and protein expression levels of Lipin2 at weeks 1, 3, 8, and 12 after birth (P<0.05). At week 3 after birth, there was no significant difference in hepatic fat content between the IUGR and control groups (P>0.05), while at weeks 8 and 12 after birth, the IUGR group had a significantly higher hepatic fat content than the control group (P<0.05). The protein and mRNA expression levels of Lipin1 were positively correlated with hepatic fat content (r=0.628 and 0.521 respectively; P<0.05), and the protein and mRNA expression levels of Lipin2 were also positively correlated with hepatic fat content (r=0.601 and 0.524 respectively; P<0.05). CONCLUSIONS Upregulation of the mRNA and protein expression levels of Lipin1 in visceral adipose tissue and Lipin2 in liver tissue can increase hepatic fat content in rats with IUGR and may be associated with obesity in adulthood.

Objective To investigate the effects of different time duration hip bathing with traditional Chinese medicine for rehabilitation of rats with anal edema, which can provide evidence for a best effective hip bathing method in the clinical application. Methods The rat model of anal edema was induced with carrageenan injection. Ninty six SD rats were divided into early intervene and latter intervene batches, every batches were randomly divided into six groups; normal control group 1, normal control group2, model matched groupl, model matched group2, hip bathing with TCM groupl, hip bathing with TCM group2. Hip bathing time duration were lOminutes and 20minutes. The rehabilitation of rats anal edema were observed. Results The comparison has been made among edema area, the ratio of dry/wet weight, microcirculation change, skin temperature, the difference is statistically significant in TCM early intervene hip bathing groups (P < 0. 05). There was a significant difference of edema proportion with 20 minutes duration between TCM hip bathing groups and model control groups (P < 0. 01 ). The comparison has been made among the ratio of dry/wet weight, microcirculation change, the difference is statistically significant in TCM latter intervene hip bathing groups(P< 0. 05). Histopathological examination showed local tissue inflammatory cell infiltration, the loosen degree of tissue space and capillary congestion of modle group were improved. Conclusions Hip bathing with traditional Chinese medicine in early intervene have obvious effect on rehabilitation of rats with anal edema, which can dispell anal edema, improving microcirculation could descend the temperature and promote the rehabilitation of anal edema, relieve inflammation and hyperemia. In the respect of edema proportion relieving, hip bathing with 20 minutes duration showed better effect than 10 minutes.

Background and Objective:Proton magnetic resonance spectroscopy(MRS) of the liver in vivo is in experimental phase. MRS observation on liver cancer after transcatheter arterial chemoembolization (TACE)has seldom been reported.This study was to investigate the value of MRS in assessing the metabolic changes of hepatocellular carcinoma(HCC) after TACE.Methods:Twenty-five consecutive patients with pathologically confirmed HCC received 1 H MRS of all hepatic lesions using 1.5T whole body MR scanner before TACE and at 3-10 days after TACE.Choline-to 1ipid(Cho/Lip), glycogen/gIucose-to-lipid(Glu/Lip), and glutamine/ glutamate-to-lipid(Gix/Lip)ratios were measured and analyzed statistically.Results:The Cho/Lip,Glu/Lip,and Gix/Lip ratios were 0.21±0.08.0.11± 0.05,and 0.28±0.10 before TACE,respectively,and were 0.10±0.08,0.07±0.07,0.18±0.12 after TACE, respectively, with significant differences(P<0.05).Conclusion: Using MRS can evaluate the early metabolic responses of HCC to TACE.

OBJECTIVETo explore the pathological basis of diffusion-weighted imaging (DWI) findings in hepatocellular carcinoma (HCC) after transcatheter arterial chemoembolization (TACE).

METHODSDWI was performed in 15 patients with HCC treated by TACE within 24 - 48 hours before II-phase operation. The DWI findings of the liver lesions were analyzed and correlated with pathological findings including macroscopic observation, HE staining and immunohistochemical staining for bFGF.

RESULTS(1) The viable tumor area showed mostly hypersignal intensity (12/15), whereas coagulative necrotic lesions showed hyposignal (8/15) or isosignal intensity (6/15). The ADC values of zones of viable tumor and necrosis in tumor were (1.42 +/- 0.16) x 10(-3) mm(2)/s and (1.58 +/- 0.18) x 10(-3) mm(2)/s, respectively. There was a significant difference of ADC values between the two zones (t = 2.618, P < 0.05). (2) There was a significant difference in ADC values of viable tumor between well and poorly differentiated tumors (t = -2.646, P < 0.05). The distinction of ADC values of the whole tumor was significant among tumors with different degree of necrosis (chi(2) = 7.236, P < 0.05). (3) A negative correlation was observed between bFGF protein expression index and ADC values of viable parts of the tumors in the study group (r = -0.552, P = 0.033).

CONCLUSIONDWI shows certain characteristic features of the HCC after TACE, and can be used to distinguish viable and necrotic tumor tissues in HCC after TACE.

Objective:To investigate the safety and effectiveness of Neuroform Atlas stent-assisted coiling in the endovascular treatment of intracranial aneurysms.Methods:This was a retrospective, single-center observational study of 77 patients who underwent endovascular treatment of intracranial aneurysms using the Neuroform Atlas device at the Department of Neurology, People′s Liberation Army General Hospital from July 2020 to May 2022. There were 34 males and 43 females, with a median (range) age of 59 (23-81) years. The degree and effect of aneurysm embolization were evaluated by modified Raymond grading post procedure and after 6 months. Complications occurring during the perioperative period were recorded. Vaso computed tomography was performed immediately after the operation to assess stent opening and adherence. Digital subtraction angiography was performed 6 months after discharge and the aneurysm was classified as cured, stable, or recurrent.Results:A total of 87 Atlases were successfully released in 77 cases. Angiography performed immediately after the embolization revealed 19 (24.7%) modified Raymond grade Ⅰ, 10 (13.0%) grade Ⅱ, and 48 (62.3%) grade Ⅲa cases. Three perioperative complications were observed including thrombotic events in 2 cases and stent migration in 1 case. A follow-up angiogram was available for 47 aneurysms, and showed that modified Raymond grade Ⅰ occlusion was achieved in 38 (80.9%) cases, grade Ⅱ in 2 (4.3%) cases, and grade Ⅲa in 7 (14.9%) cases. At the 6-month follow-up, 38 patients were cured and 7 were stable, whereas 2 patients experienced a recurrence of aneurysm. Stenosis of the parent artery occurred in 3 (6.4%) cases, including 2 at the head and 1 inside the stent.Conclusions:The results of this preliminary study suggest that Neuroform Atlas stent-assisted coiling has a high occlusion rate and low incidence of complications in the endovascular treatment of aneurysms. However, the effectiveness of this procedure for large aneurysms and long-term outcomes require further investigation.

Objective To report and study a case of sporadic family fatal insomnia(SFFI)on its. Methods Investigate clinical characteristics and family disease history of a suspect FFI patient His clinical characteristic was analyzed, he and his 14 family members genomic DNA was extracted by standard techniques from their and blood detected with polymersse chain reaction(PCR) method and DNA sequencing to find out his prion protein (PrP)gene mutation. The patient's CSF was detected with Western-Blot method for 14-3-3 brain protein. Results The patient was diagnosed as an sporadic FFI by his developed sleep disturbance and changes in sleep-awake rhythm, motor abnormalities, mental disorder, dementia, autonomic dysfunction ; his family history ; his 14-3-3 brain protein-positive (CSF) and analysis results of his PrP gene (codon point mutation D178N and methionine homozygosity at position 129M/M). Suggesting that in the future to identify CJD and FFI patients, screening should focus on clinical symptoms and laboratory results. The PrP gene of 14 family members did not appear Mutation, and there is no person suffering from the same disease. Conclusions The case was diagnosed as a sporadic familial fatal insomnia. Analysis of suspicious patients' genomic DNA for PrP gene mutation might be very important for FFI diagnosis because there exist many difficulties in clinical laboratory evaluation. This patient might be the first SFFI patient reported in China and the case finding might have momentousness in clinical and basical study.

Objective:To investigate the perioperative adverse events and complications of flow-diverter devices in the treatment of unruptured intracranial aneurysms.Methods:This is a retrospective case series study. The clinical and imaging data of 174 patients with unruptured intracranial aneurysms treated with flow-diverter devices in the Department of Neurointervention, Department of Neurology, the First Medical Center of Chinese People′s Liberation Army General Hospital from January 2020 to January 2024 were retrospectively analyzed. There were 63 males and 111 females, with an age of (53.9±11.4) years (range:23 to 76 years).The occurrence, development and outcome of perioperative complications and related adverse events during treatment were collected and analyzed. The degree of aneurysm embolization was evaluated using the O′Kelly-Marotta (OKM) grading system,with OKM grade C and D as successful occlusion.Results:A total of 187 flow-diverter devices (from 7 different brands) were implanted in 174 patients (with 294 aneurysms). Of these, 151 cases involved standalone stent embolization, 26 cases involved stent embolization combined with coil assistance, and 5 cases involved the use of two flow-diverter devices simultaneously. Twenty-nine cases (16.7%,29/174) suffered intraoperative adverse events, including 10 cases of poor stents deployment, 3 cases of stents migration into the aneurysm sac, 1 cases of abnormal guidewire movement, 4 cases of ischemic events. Complications occurred in 10 patients (5.7%, 10/174), and neurological deficits occurred in 5 patients (2.9%, 5/174). A total of 129 patients completed follow-up for more than 12 months after surgery. There were 117 aneurysms with OKM grade D and 22 with OKM grade C, showing a satisfactory healing rate of 77.7% (139/179).Conclusion:The effect of flow-diverter devices in the treatment of intracranial aneurysms is satisfactory, but complications and adverse events cannot be ignored, especially the relatively high incidence of perioperative adverse events, which requires neurointerventional physicians to be vigilant.
