Objective:To retrospectively summarize the clinical characteristics and treatment of 49 patients with hyperthyroid cardiopath and to explore the diagnosis and treatment methods of hyperthyroid cardiopathy.Methods:A total of 49 patients with hyperthyroid cardiopath(HC group) who were successfully treated and followed up in the Department of Endocrinology, Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine, from January 2016 to December 2021 were collected, and 85 cases of Graves′ disease without heart disease were collected as the control group(GD group). The medical history, laboratory tests, and echocardiographic parameters of the two groups were compared. Differences in thyroid and cardiac indicators before and after treatment in the HC group were summarized, along with the dosage of β-receptor blockers used in treating different types of conditions(atrial fibrillation and heart failure.Results:Patients in the HC group were older and had a longer duration of hyperthyroidism than those in the GD group( P<0.001, P=0.002). There were no significant differences in thyroid hormone levels between the two groups except for reverse triiodothyronine(rT 3). Age and rT 3 were independent risk factors of hyperthyroid cardiopathy. rT 3 level was linearly positively correlated with brain natriuretic peptide, systolic pulmonary artery pressure, left artrium diamete (LAD) and left ventricular end-systolic diameter(LVDs; r=0.352, P<0.001; r=0.392, P=0.019; r=0.202, P=0.029; r=0.242, P=0.028). In patients of HC group, free triiodothyronine(FT 3) level returned to normal range after 2.87(1.63, 5.53) months of treatment with radioiodine(41/49) or antithyroid drugs(8/49), while brain natriuretic peptide, LAD, LVDs, and systolic pulmonary artery pressure declined after 5.00(1.25, 8.00) months of treatment. Non-selective β-receptor blockers were used for both hyperthyroid heart failure and atrial fibrillation, and there was no statistically significant difference in dosage[(86.52±47.83)mg vs(88.67±47.19)mg, P>0.05]. Conclusions:rT 3 may be a biomarker of hyperthyroid cardiopath and indicate the severity of hyperthyroidism. β-receptor blockers are crucial in treating patients with hyperthyroidism who develop atrial fibrillation and heart failure.

Purpose: This study compared the efficacy of heat insulation between 5% dextrose and 0.9% saline in radiofrequency ablation (RFA). Accordingly, temperature variations and maximum temperatures were assessed at identical distances and heat field distributions. Methods: Cubes of porcine liver tissue, measuring 10 mm across, were selected to precisely align the ablation boundary with the tissue boundary. An 18-gauge electrode with a 7-mm tip was inserted into each cube (10 per group) in a stainless-steel cup containing 40 mL of 5% dextrose or 0.9% saline. Fixed ablation was performed for 3 minutes using continuous mode at 30 W, simulating the typical thermal environment during thyroid RFA. Real-time temperature measurements were recorded by sensors positioned 0, 1, 3, and 5 mm from the cube’s edge. A comparative analysis was conducted to assess the maximum temperature, temperature variation, and duration of temperatures exceeding 42℃. Results: In both groups, the temperature curve declined with increasing distance from the edge of the ablated tissue. However, 0.9% saline exhibited higher maximum temperatures at 1, 3, and 5 mm compared to 5% dextrose (1 mm: 44.55°C±5.25°C vs. 34.68°C±3.07°C; 3 mm: 39.64°C±2.53°C vs. 29.22°C±2.21°C; 5 mm: 38.86°C±2.14°C vs. 28.74°C±2.51°C; all P<0.001). Considering a nerve injury threshold of 42°C, the 0.9% saline also displayed a greater proportion of samples reaching this temperature and a longer duration of temperatures exceeding it (P<0.05). Conclusion The heat insulation efficacy of 5% dextrose at 1-5 mm exceeds that of 0.9% saline at identical distances and in a common thermal environment during thyroid RFA.

Objective:To observe the efficacy and safety of Tofacitinib in treating elderly rheumatoid arthritis(RA), in order to provide clinical evidence.Methods:In the randomized control trial, a total of 90 elderly RA patients admitted to the Department of Rheumatology of the First Affiliated Hospital of Soochow University from January 2019 to January 2021 were selected and divided into Methotrexate group(MTX group, MTX 10mg, qw, n=45)and Tofacitinib group(TOF group, oral 5mg, bid, n=45). The efficacy and safety of the two groups were evaluated at week 12.The primary endpoint was the proportion of patients meeting the American College of Rheumatology 50%(ACR50)improvement response criteria at week 12.Secondary endpoints included ACR20/70 improvement response, proportion of patients who met treat-to-target(T2T)criteria, including Disease Activity Score in 28 joints using erythrocyte sedimentation rate(DAS28-ESR), Disease Activity Score in 28 joints using C-reactive protein level(DAS28-CRP), clinical disease activity index(CDAI), and simplified disease activity index(SDAI), and patient-reported outcomes(PROs)which included changes compared to baseline in pain visual analog scale(VAS)and Health Assessment Questionnaire Disability Index(HAQ-DI)score, at week 12.Safety outcomes including drug-related adverse events, serious adverse events, dropping out due to adverse events, and deaths were assessed throughout.Results:Five patients in each group withdrew from the trial due to adverse events, and the number of patients who finally completed the observation was 40 in each group.At week 12, the ACR50 response rate was higher in TOF group than in MTX group[35%(14/40) vs.12.5%(5/40), χ2=5.591, P=0.018)], achieving the primary endpoint.When comparing TOF vs.MTX group, the ACR20 response rate[55%(22/40) vs.25%(10/40), χ2=7.500, P=0.006]and ACR70 response rate[25%(10/40) vs.7.5%(3/40), χ2=4.501, P=0.034], and proportions of indexes of disease remission including DAS28-ESR<2.6[25%(11/40) vs.7.5%(3/40), χ2=4.501, P=0.034], or DAS28-CRP<2.6[27.5%(11/40) vs.7.5%(3/40), χ2=5.541, P=0.019], or CDAI≤2.8[30%(12/40) vs.10%(4/40), χ2=5.000, P=0.025], or SDAI≤3.3[27.5%(11/40) vs.7.5%(3/40), χ2=5.541, P=0.019], and the proportions of patients with low disease activity including DAS28-ESR≤3.2[32.5%(14/40) vs.12.5%(5/40), χ2=5.591, P=0.018], or DAS28-CRP≤3.2[32.5%(14/40) vs.12.5%(5/40), χ2=5.591, P=0.018], or CDAI≤10[37.5%(15/40) vs.17.5%(7/40), χ2=4.013, P=0.045], or SDAI≤11[37.5%(15/40) vs.15%(6/40), χ2=5.230, P=0.022], as well as changes compared to baseline data in pain VAS[(26.51±8.32)scores vs.(14.16±4.39)scores, t=8.371, P<0.001]and in HAQ-DI score(0.65±0.24 vs.0.32±0.06, t=9.387, P<0.001)were all better in the TOF group than in the MTX group at week 12.During the 12-week observation period, the number of patients with infection and hyperlipidemia was higher in TOF group than in MTX group, while the number of patients with abnormal blood cell count and liver function was lower than that in MTX group, but the differences were not statistically significant(all P<0.05). Conclusions:Tofacitinib has good efficacy and safety in the elderly RA.In patients over 70 years of age who are at high risk of infection, tofacitinib should be used with caution.

Objective: : The surgical management of trigeminal neuralgia (TN) caused by petrous apex meningioma (PAM) is still a challenge because of the lesion’s deep location and the surrounding complex structures. The authors describe the intradural anterior transpetrosal approach (ATPA) and its effect on the treatment of TN secondary to PAM. Methods: : A retrospective analysis of 15 patients with TN secondary to PAM who underwent surgery via the intradural ATPA was conducted. The key techniques, which included drilling off the petrosal apex (PA) and opening the upper wall of Meckel’s cave (MC), are described in detail. Results: : Total removal of the tumor and complete pain relief (Barrow Neurological Institute I) were achieved in all 15 patients without significant morbidity. Five patients developed new facial numbness postoperatively, which disappeared within three months after surgery. The postoperative magnetic resonance imaging showed temporal lobe swelling in three patients, but no clinical symptoms. One patient had cerebrospinal fluid leakage and was managed with bed rest and temporary lumbar drainage. One patient had an intracranial infection and was treated with antibiotics. By the last follow up, no patients had pain relapse or/and tumor recurrence. It is worth noting that the vascular compression at the root of the trigeminal nerve was found in one patient during the operation. Conclusion : Our experience suggests that drilling off the PA and opening the upper wall of the MC are key elements for a good outcome of the treatment of TN secondary to PAM. The intradural ATPA has the advantages for both tumor resection and pain relief.

ObjectiveTo investigate the abnormal changes of gray matter structure covariant network in post-stroke aphasia (PSA) patients. MethodsFrom June, 2019 to March, 2022, 15 PSA patients (patient group) from Dongzhimen Hospital, Beijing University of Chinese Medicine and Beijing Bo'ai Hospital were recruited, as well as 15 healthy subjects (control group). Their brain structure magnetic resonance imaging data were collected. The brain covariant network was constructed based on gray matter volume correlation, and graph theory analysis method was used to evaluate the global and node network level topology properties of structural covariant network. The differences of gray matter covariant network properties between patients and controls were compared. ResultsThere was no significant difference in the global network level topology properties between two groups (P > 0.05). At the nodal level, compared with the control group, the betweenness decreased in the right middle frontal gyrus, right posterior cingulate gyrus, right amygdala, left middle occipital gyrus, and increased in the right inferior frontal gyrus and the right suboccipital gyrus of the insula operculum (P < 0.05); the node degree decreased in the left superior frontal gyrus, left anterior cingulate and paracingulate gyrus, left hippocampus and left amygdala, while it increased in the right inferior frontal gyrus, left supplementary motor area, right superior occipital gyrus, right inferior occipital gyrus, and right lentiform pallidus (P < 0.05); the node efficiency decreased in the left anterior cingulate and paracingulate gyrus, left hippocampus, left amygdala, left temporal pole: superior temporal gyrus, and increased in the inferior frontal gyrus of right insula, left supplementary motor area and right suboccipital gyrus (P < 0.05). ConclusionThe abnormal reduction of node network properties in some brain regions in the left hemisphere of PSA patients may be a characteristic structural covariation pattern, and there may be some compensation in the right hemisphere of the structural network in some brain regions.
