Objective:To explore the effects of multi-disciplinary nutrition support team on nutritional status and quality of life in lung cancer patients undergoing chemotherapy, so as to provide reference for the formulation of nutritional intervention plans for lung cancer patients undergoing chemotherapy.Methods:This was a quasi experimental study. A total of 74 patients with lung cancer undergoing chemotherapy in Jinshan Hospital of Fudan University from February 2021 to July 2022 were selected as the research object by convenient sampling method. They were divided into two groups according to their admission time, 37 cases of patients from February to August 2021 for the control group, using conventional nursing interventions, 37 cases of patients from September 2021 to July 2022 for the observation group, with multi-disciplinary nutrition support team. A follow-up was conducted for three chemotherapy cycles, serum nutrition indicators and quality of life were compared between the two groups.Results:There were 27 males and 10 females in the control group, aged (68.14 ± 6.82) years old. There were 30 males and 7 females in the observation group, aged (65.92 ± 9.17) years old. There was no significant difference in the serum nutrition indicators and quality of life before intervention between the two groups (all P>0.05). The serum total protein, albumin and prealbumin levels in the observation group were (69.41 ± 5.87), (38.11 ± 4.04) g/L, and (243.57 ± 67.58) mg/L, which were higher than those in the control group (65.54 ± 8.33), (35.78 ± 5.39) g/L, and (200.84 ± 60.84) mg/L, the differences were statistically significant ( t=-2.31, -2.10, -2.86, all P<0.05). After intervention, the observation group showed higher scores for emotional function and overall health/life quality, with (88.29 ± 16.72), (60.36 ± 13.24) points, compared to the control group with (76.80 ± 17.58), (46.40 ± 16.38) points. The scores for fatigue, nausea/vomiting, insomnia, and loss of appetite were (34.53 ± 22.19), (11.26 ± 8.83), (20.72 ± 16.39), (24.32 ± 18.67) points in the observation group, which were lower than the scores in the control group (45.65 ± 22.95), (25.68 ± 18.67), (36.94 ± 23.29), (40.54 ± 22.41) points, all the differences were statistically significant ( t values were -4.03-4.24, all P<0.05). Conclusions:During chemotherapy in lung cancer patients, the multidisciplinary nutrition support team has been shown to significantly improve the patients′ nutritional status and enhance their quality of life.

Objective:To explore the clinical characteristics and genetic variant of a patient with desminopathy manifesting with atypical symptoms.Methods:A patient who was admitted to the Department of Neurology of Jing′an District Central Hospital on February 24, 2021 was selected as the study subject. Clinical data, laboratory tests, muscle pathology, muscle magnetic resonance imaging (MRI) and genetic testing of the patient were retrospectively analyzed.Results:The patient had developed myalgia after lower limb activity, and gradually developed asymmetrical muscle weakness and atrophy of the lower limbs. Cardiac examination revealed atrioventricular block and decreased left ventricular diastolic function. Muscle MRI showed that semitendinosus, sartorius, gracilis, fibula, gastronemius and supinator muscles were selectively involved at the early stage. Muscle biopsy confirmed pathological changes of desmin positive myofibrils. Genetic testing revealed that the patient has harbored a c. 1024A>G (p.n342d) missense variant in exon 6 of the DES gene. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), the variant was rated as likely pathogenic (PS4_moderate+ PM2_supporting+ PP3_moderate+ PP1). Conclusion:Desmin disease has a great clinical heterogeneity. Postexercise myalgia of lower limbs is a rare clinical phenotype. For patients harboring the c. 1024A>G (p.n342d) variant of the DES gene, in addition to semitendinosus and fibula, Cardiac involvement is relatively insidious and easy to be ignored in clinic. Timely muscle MRI, muscle biopsy and gene detection will help the early diagnosis of the disease.

Objective:To explore the clinical, imaging, and genetic characteristics of an adult patient with sporadic Neuronal intranuclear inclusion disease (NIID).Methods:A patient who had visited the First People′s Hospital of Chenzhou on August 6, 2023 was selected as the study subject. Results of clinical examination, neuroimaging, and genetic testing were retrospectively analyzed along with a literature review. The number of GGC trinucleotide repeats in the 5′-untranslated region of the NOTCH2NLC gene was determined by GC-PCR. Results:The patient had presented with episodic encephalopathy, with enhanced magnetic resonance imaging showing enhancement features of the posterior cerebral cortex during the period of acute episode. Genetic testing revealed an increased number of GGC repeats ( n = 97) in the 5′- untranslated region of the NOTCH2NLC gene, which confirmed the diagnosis of NIID. Conclusion:Clinical attention should be paid to the enhanced MRI findings of patients with adult-onset NIID, for whom posterior cortical enhancement may be characteristic manifestation during the acute phase of encephalopathy-like episode.

ObjectiveTo investigate the efficacy and mechanism of saffron floral bio-residues（SFB） in the treatment of hyperuricemia（HUA） combined with gouty arthritis（GA） in a compound compatibility setting. MethodScreening candidate control Chinese medicines for compound and SFB based on network target distance calculation and data analysis. After adaptive feeding of 80 SD rats for 7 days， 10 rats were randomly selected as the blank group， while the remaining 70 rats were intraperitoneally injected with 3% potassium oxonate and orally administered with 1% adenine for 14 consecutive days. On the 13^th day， rats were injected with 2.5% sodium urate solution into the right ankle joint cavity to induce swelling of the joint capsule on the opposite side， inducing a HUA combined with GA model. At the same time， the modeling rats were randomly divided into 7 groups， including the model group， benzbromarone group（positive drug， 0.02 g·kg^-1）， Tongfengshu tablets group（9 g·kg^-1）， Tongfengshu granules group（9 g·kg^-1）， SFB granules group（3.6 g·kg^-1）， Plantaginis Semen granules group（3.6 g·kg^-1）， and new formula group（SFB replacing Plantaginis Semen in Tongfengshu granules， 9 g·kg^-1）， with 10 rats in each group. Each treatment group was orally administered with the corresponding drugs according to body weight， while the control and model groups were given equal volume of distilled water by gavage once a day for 14 consecutive days. After 14 days of synchronous administration and modeling， changes in gait， ankle joint swelling and mechanical pain threshold in rats were observed， and serum uric acid， creatinine， urea nitrogen and xanthine oxidase（XOD） were measured. Enzyme-linked immunosorbent assay（ELSIA） was used to detect the levels of tumor necrosis factor（TNF）-α， interleukin（IL）-1β and IL-6 in rat serum， hematoxylin-eosin（HE） staining was used to observe the pathological changes in the liver， kidney and ankle joints of rats， Western blot was used to detect the expression levels of uric acid transporter 1（URAT1）， glucose transporter 9 （GLUT9）， organic anion transporter 1（OAT1）， adenosine triphosphate（ATP） binding cassette transporter G2（ABCG2）， and liver XOD proteins. ResultThrough network pharmacology analysis， Plantaginis Semen was selected as a candidate control herb， and Tongfengshu tablets was used as a compound compatibility environment to explore the efficacy of SFB in reducing blood uric acid levels and treating GA. Animal experiments showed that compared with the blank group， the gait score and joint swelling degree of the model group were significantly increased， and the mechanical pain threshold was significantly decreased（P<0.01）. Compared with the model group， the gait score， joint swelling degree and mechanical pain threshold of rats in each medication group were improved to varying degrees. Biochemical indicators showed that compared with the blank group， the serum uric acid， creatinine， urea nitrogen and XOD levels of the model group were significantly increased（P<0.01）. Compared with the model group， the serum uric acid and XOD levels of rats in each treatment group were significantly decreased（P<0.01）. ELISA results showed that compared with the blank group， the levels of serum TNF-α， IL-1β and IL-6 in the model group were significantly increased（P<0.01）. Compared with the model group， the levels of TNF-α， IL-1β and IL-6 in the benzbromarone group， Tongfengshu tablets group， Tongfengshu granules group and new formula group were significantly reduced（P<0.05，P<0.01）. Western blot results showed that compared with the blank group， the expression levels of URAT1 and GLUT9 proteins in renal tissue and OXD protein in liver tissue of the model group were significantly increased， while the expression levels of renal OAT1 and ABCG2 were significantly decreased（P<0.01）. Compared with the model group， the expression levels of renal URAT1 and GLUT9 in the SFB granules group， Tongfengshu granules group and new formula group were significantly decreased， while the expression levels of renal OAT1 and ABCG2 were significantly increased， and the expression of XOD protein in liver tissue was significantly decreased（P<0.05， P<0.01）. Pathological analysis showed that focal infiltration of neutrophils， cell necrosis and nuclear fragmentation were observed in the liver tissue of the model group， sodium urate deposition crystals and tubular dilation appeared in renal tissue， synovial hyperplasia and inflammatory cell infiltration appeared in ankle joint. Compared with the model group， the abnormal degrees of liver， kidney and ankle joint tissue of rats in each treatment group were alleviated. ConclusionThe new formula of SFB replacing Plantaginis Semen has the same effect in the treatment of HUA combined with GA. This study proposes a new strategy to investigate the efficacy of new resources of Chinese medicine in a compound compatibility environment， which can provide a new demonstration for the research and development of new resources of Chinese medicine.

ObjectiveTo observe the clinical efficacy of Danzhi Jiangtang capsules with the functions of replenishing Qi， nourishing Yin， and dredging collaterals on patients with type 2 diabetes mellitus （T2DM） combined with lower-extremity macroangiopathy and serum levels of homocysteine （Hcy） and cystatin C （Cys C）. MethodA total of 80 eligible patients who were treated in the department of endocrinology of the First Affiliated Hospital of Anhui University of Chinese Medicine from May 2017 to December 2019 were randomized into the treatment group （40 cases） and control group （40 cases）. Both groups received the basic therapies for diabetes and Danzhi Jiangtang capsules （oral） was added to the treatment group. The levels of glycosylated hemoglobin A1c （HbA1c）， fasting plasma glucose （FPG）， 2-hour postprandial glucose （2 hPG）， fasting C-peptide （C-P）， and 2-hour postprandial C-peptide （2 hC-P）， triglycerides （TG）， total cholesterol （TC）， high density lipoprotein cholesterol （HDL-C）， and low density lipoprotein cholesterol （LDL-C） and serum levels of Hcy and Cys C were measured and the traditional Chinese medicine（TCM） syndrome scores were calculated before and after treatment in the two groups. ResultAfter 12 weeks of treatment， levels of HbA1c， FPG， and 2 hPG were lower than those before treatment in the two groups （P<0.05）. Levels of C-P （P<0.05） and 2 hC-P were higher than those before treatment in the two groups. After treatment， levels of HbA1c， FPG， and 2 hPG in the treatment group were lower than those in the control group （P<0.05）， while levels of C-P and 2 hC-P showed no significant difference between two groups. After treatment， the levels of TG， TC， and LDL-C were lower than those before treatment （P<0.05） and HDL-C level was higher than that before treatment （P<0.05） in both groups. After treatment， levels of TG and LDL-C in the treatment group were lower than those in the control group （P<0.05）， and levels of TC and HDL-C demonstrated no significant difference between two groups. After the treatment， the TCM syndrome score was lower than that before the treatment in both groups （P<0.05） and lower in the treatment group than in the control group （P<0.05）. The overall effective rate of the treatment group was higher than that of the control group （χ^２=7.585， P<0.05）. The levels of Cys C and Hcy were lower than those before treatment in the two groups （P<0.05） and lower in the treatment group than in the control group （P<0.05）. Doppler echocardiography of the lower limbs showed no obvious improvement in the control group after treatment. However， for the treatment group， slight decrease in intima-media thickness of the lower limb arteries and a slight reduction in the plaque area were observed， but the difference was not statistically significant. ConclusionDanzhi Jiangtang capsules has definite therapeutic effect on T2DM combined with lower-extremity macroangiopathy， which can improve glucolipid metabolism and reduce serum levels of Hcy and Cys C. This study can serve a reference for the prevention and treatment of T2DM combined with macroangiopathy.

Objective:To explore the clinical and imaging characteristics of patients with unruptured intracranial aneurysms accompanied by sentinel headache.Methods:Forty patients with unruptured intracranial aneurysms confirmed by DSA/CTA and accompanied by sentinel headache admitted to Department of Neurology, First Affiliated Hospital of Xiangnan University from January 2018 to August 2023 were selected as the study subjects; the clinical and imaging characteristics of these patients were summarized. Forty-four patients with unruptured intracranial aneurysms without sentinel headache and 40 patients with subarachnoid hemorrhage caused by ruptured intracranial aneurysms admitted to the hospital at the same period were selected as controls. The differences in aneurysm length (maximum diameter), morphology, tumor length (maximum diameter)/neck width (AR), and risk score for rupture of intracranial aneurysms (scores of population, hypertension, age, size of aneurysm, earlier aneurysm rupture, site of aneurysm [PHASES]) among the 3 groups were analyzed.Results:Among the 40 patients with unruptured intracranial aneurysms accompanied by sentinel headache, 20 (50%) presented with pain localized at the lateral frontal and orbital regions, 3 (7.5%) with pain at the posterior neck region, and 17 (42.5%) with irregular headache sites; 34 (85%) had new onset headache, and 6 (15%) had changes in headache nature besides chronic headache; 24 patients (60%) had posterior communicating artery aneurysm, 12 (30%) had internal carotid artery aneurysm, 1 (2.5%) had middle cerebral artery aneurysm, and 3 (7.5%) had vertebral artery dissection aneurysm; 36 (90%) had irregular aneurysm morphology. Compared with patients with unruptured intracranial aneurysms without sentinel headache, patients with unruptured intracranial aneurysms accompanied by sentinel headache and those with subarachnoid hemorrhage caused by ruptured intracranial aneurysms had larger aneurysm length (maximum diameter), higher proportion of irregular morphology, higher AR value, and higher PHASES scores, with significant differences ( P<0.05). Compared with patients with subarachnoid hemorrhage caused by ruptured intracranial aneurysms, patients with unruptured intracranial aneurysms accompanied by sentinel headache had larger aneurysm length (maximum diameter) and higher PHASES scores, with significant differences ( P<0.05). Conclusion:Sentinel headache is common in patients with unruptured posterior communicating artery aneurysms, and the relatively specific headache pattern is sudden periorbital pain or posterior neck pain; patients with unruptured intracranial aneurysms accompanied by sentinel headache have a higher rupture risk due to the larger size, more irregular shape, higher AR value of the aneurysm, therefore, same attention should be payed to these patients as those with ruptured aneurysms in clinical practice.

Objective:To investigate the clinical and imaging features of spontaneous convexal subarachnoid hemorrhage (cSAH) with acute cerebral infarction.Methods:Nine patients with cSAH complicated with acute cerebral infarction, admitted to our hospital from January 2018 to October 2021, were selected. The clinical data and efficacy of these patients were retrospectively analyzed.Results:The time from cSAH to the onset of acute cerebral infarction was 5-144 h, with median time of 2 d. The most common bleeding site of cSAH was the parietal lobe ( n=6); cSAH in the ipsilateral side of acute cerebral infarction was noted in 4 patients. Six patients had middle cerebral artery stenosis or occlusion, and 2 patients had anterior cerebral artery stenosis or occlusion. Hypertension ( n=7) was the most common primary disease; 7 patients were treated with antiplatelet drugs, anticoagulants and/or stents. The follow-up at 3 months after cSAH showed that 6 patients had good prognosis and one had poor prognosis. Conclusions:The cSAH often occurs 2 d after acute cerebral infarction; intracranial artery stenosis or occlusion may be the main cause of the disease. In patients complicated with cSAH, active antiplatelet, anticoagulation and/or stent therapy do not increase the risk of bleeding, and the prognosis is good.

Objective:To investigate the diagnostic value of contrast-enhanced ultrasonography (CEUS) in evaluating the severity of renal artery stenosis.Methods:Eighty six patients with suspected renal artery stenosis admitted to Shanxi Provincial People′s Hospital from January 2018 to July 2021 were enrolled in the study. All patients underwent digital subtraction angiography (DSA), Doppler ultrasonography (DUS) and CEUS examinations. With DSA results as gold standard the sensitivity, specificity, accuracy, positive predictive value (PPV) and negative predictive value (NPV) of CEUS and DUS in the diagnosis of renal artery stenosis were analyzed. The consistency between CEUS and DSA in the diagnosis of renal artery stenosis was evaluated. The accuracy of DUS and CEUS in diagnosis of renal artery stenosis was assessed by the area under receiver operating characteristic (ROC) curve (AUC) and compared between groups.Results:Among 153 renal arteries from 86 patients examined by DSA, 101 showed the stenosis ≥30% (49 left and 52 right renal arteries), and there were 31, 45, 20 and 5 renal arteries with grade I, II, III and IV stenosis. The sensitivity and specificity of DUS in the diagnosis of renal artery stenosis were 74.3% (75/101) and 76.9% (40/52),respectively. DUS showed 21, 42, 20 and 4 renal arteries with grade Ⅰ, Ⅱ, Ⅲ and Ⅳ stenosis, respectively. The sensitivity and specificity of CEUS in the diagnosis of renal artery stenosis were 88.1% (89/101) and 86.5%(45/52), respectively. CEUS showed 26, 43, 23 and 4 renal arteries with grade Ⅰ, Ⅱ, Ⅲ and Ⅳ stenosis, respectively. There was a significant difference between DUS and DSA in grading of renal artery stenosis (χ2=4.447, P=0.03),and there was a moderate consistency between DUS and DSA ( Kappa=0.480). There was no significant difference between CEUS and DSA in grading renal artery stenosis (χ2=0.842, P=0.36) with a good consistency ( Kappa=0.730). The AUC of CEUS in diagnosis of renal artery stenosis was higher than that of DUS [0.873 (95% CI: 0.808-0.938) vs. 0.756 (95% CI:0.673-0.839); Z=4.361, P<0.01]. Conclusion:The study suggests that contrast-enhanced ultrasonography may be used as a diagnostic method for grading renal artery stenosis.
