Objective To investigate the relationship between optic d isc hemorrhage and localized retinal never fiber layer defects (RNFLDs) in norma l-tension glaucoma. Methods In 83 patients with normal-tensi on glaucoma, the cumulative frequency and quadrantal distribution of optic disc hemorrhages were retrospectively analyzed. The neighboring relation between opti c disc hemorrhages and RNFLDs in a same quadrant and the changes of correspondin g retinal never fiber layer (RNFL) after the occurrence of optic disc hemorrhage s were observed by tridimensional photochromy of ocular fundus. Results (1) The occurrences and distribution of optic disc hemorrhages: 29 of 83(34.94%) patients (33 eyes) had totally 58 occurrences, including 39 in infer iotemporal area, 14 in superiotemporal area, and 5 in other area. (2) The relati onship of neighborhood between optic disc hemorrhages and RNFLDs: in the availab le tridimensional photochrome, 23 occurrences in 15 patients (16 eyes) were foun d with cuneiform RNFLDs in the same quadrant, in which 22 was near the border of cuneiform RNFLDs. (3) The changes of corresponding retinal never fiber layer (R NFL) after the occurrence of optic disc hemorrhages: the photochromes of 24 occu rrences in 20 patients (21 eyes) were kept well in the initial and the 2-year f ollow-up periods, while the changes of RNFL were found in each region correspon ding to the 19 occurrences (in inferiotemporal or superiotemporal area) in the i nitial photochrome, including 7 cuneiform defects with various sizes, and 12 dev eloped localized RNFLDs next to the initial hemorrhages in the optic disc. No ob vious localized RNFL corresponding to the other 5 occurrences (1 in inferiotempo ral, 1 in superiotemporal, and 3 in other areas) were found in the follow-up pe riod. Conclusion Optic disc hemorrhages in normal-tension gla ucoma occur mostly in inferiotemporal area, and secondly in superiotemporal area of optic disc, and the appearance of optic disc hemorrhages may suggest that th e localized RNFLDs would develop in the associated regions.

Objective To explore the difference in measurements of the same patients' bilateral ax-illary temperature during transfusion. Methods Bilateral axillary temperature 80 patients with normal temperature who underwent transfusion in hospital was measured before infusion, 30 to 35 minutes after in-fusion, and the experimental data went through statistical analysis. Results No significant difference ex-isted between both sides of the axillary temperature before transfusion, significant difference existed be-tween axillary temperature of the transfusion-side before transfusion and after transfusion, no significant dif-ference between axillary temperature of the no transfusion-side before transfusion and after transfusion, the mean values of both sides of the axillary temperature were significant after the transfusion compared with the normal values of human body in textbook,the axillary temperature of no-transfusion side was closer to the normal human axillary temperature in the textbook. Conclusions Transfusion affect axil-lary temperature,mainly on the transfusion side,so it is appropriate to take temperature in armpit side without transfusion.

This paper reviewed the studies on the effect of electroacupuncture in improving learning and memory functions in the past 10 years. It showed an overview of the mechanisms that how acupuncture worksed: promoting synaptic plasticity, regulation of microvascular injury and oxidative stress; slowing down the progress of brain cell apoptosis, inhibition of inflammatory response;regulating neurotransmitter release and protecting the ultrastructure of neurons. In addition, this paper puts forth the problems which left in the current studies.

This study was aimed to examine the expression of apoptosis-associated gene Fas in HeLa cell, explore the effects of the co-immobilized cytokines (tumor necrosis factor-alpha and interferon-gamma), and probe the potential mechanism of action. The preparation and application of the research couple IFN-gamma and TNF-alpha to the polystyrene cell culture plate were performed using the Photo-immobilization method, with different doses (20 ng/well and 200 ng/well) and synthesized optical active material. HeLa cells were treated with cytokines for two dose and 1, 3, 6 days. The result showed that the free cytokines induced HeLa apoptosis quickly, yet the HeLa apoptosis induced by co-immobilized cytokines had longer effect.

Neuropathic pain (NP) is a common complication following spinal cord injury, with an incidence rate ranging from 38% to 70%. NP typically presents as sensation of burning, electric shocks, tingling or squeezing pain resulting from somatosensory nerve damage, which exerts a negative impact on patients′ physical and psychological well-being. After spinal cord injury, glial cells are activated to induce inflammatory cascade. Accordingly, various inflammatory mediators that may disrupt the neuronal function are released to promote abnormally increased neuronal excitability and pain signal transduction. Additionally, spinal cord injury can disrupt the release of neurotransmitters and neurotrophic factors, alter ion channel activity, and thereby impair the normal pain regulatory mechanisms and further increase pain perception. The interaction of these mechanisms contributes to the occurrence and persistence of NP after spinal cord injury. However, the precise pathogenesis of NP remains incompletely elucidated, making its therapeutic efficacy uncertain and clinical management difficult. It is of great significance to thoroughly understand the underlying pathophysiological mechanisms of NP following spinal cord injury for its treatment. For this reason, the authors reviewed the research progress on the characteristics and pathophysiological mechanisms of NP following spinal cord injury, aiming to serve as a reference for further research and development of more effective targeted therapies and management strategies.

Objective To investigate the effects of gemstone energy spectrum CT atomic number method and infrared spec-troscopy for analyzing the composition of urinary calculi and to compare their values in qualitative diagnosis of urinary calculi .Meth-ods Two hundreds and sixty cases of urinary tract stones were performed the gemstone spectrum CT urinary scanning and the stone composition was identified by atomic number method .After removing stone ,the stone composition analyzed by infrared spec-troscopy served as the gold standard .Then the consistency identified by the two methods was analyzed .Results The Kappa consis-tency test results showed that the two kinds of method for identifying stone type had good consistency (Kappa=0 .787 ,P<0 .01) . The paired chi square test results showed that the difference of the two methods for identifying the stone type had no statistical sig-nificance(χ2 =6 .581 ,P=0 .254) .The stone crystal composition types measured by gemstone energy spectrum CT atomic number method were less than those measured by infrared spectroscopy .The precise quantification of the stones with different crystal struc-tures was not as accurate as that of infrared spectroscopy (calcium oxalate monohydrate and calcium oxalate dihydrate ) .Conclusion The two methods for analyzing theurinary stone composition all have clinical significance ,the stone analysis method should be se-lected according to the actual situation .

Objective:To explore the clinical characteristics of neurological syndrome associated with anti-glutamic acid decarboxylase (GAD) antibodies (Abs).Methods:Six patients with neurological syndrome associated with anti-GAD-Abs admitted to Department of Neurology, Henan Provincial People's Hospital from January 2019 to October 2022 were chosen. The clinical manifestations, imaging and laboratory results, therapeutic schedules, and follow-up prognoses of these patients were collected and summarized.Results:Three females and 3 males were included, with onset age of (54.3±17.7) years. Three patients had stiff-person syndrome (SPS), 1 had limbic encephalitis+generalized epilepsy, 1 had extralimbic encephalitis+occipital epilepsy, and 1 had cerebellar ataxia who was diagnosed with paraneoplastic syndrome associated with small cell lung cancer. Four patients had elevated level of thyroid peroxidase antibodies, and 1 patient was positive for overlapping anti-gamma aminobutyric acid B receptor antibodies and Amphiphysin antibodies. Two patients with SPS had failed lumbar puncture; 1 had slightly increased white blood cells and proteins in cerebrospinal fluid (CSF); the remaining 3 patients were basically normal. Specific oligoclonal bands in CSF were observed in 2 patients. Brain MRI showed abnormal signals in the bilateral occipital lobes in 1 patient, and no specific inflammatory lesions in other patients. All patients accepted corticosteroids and intravenous immunoglobulin/plasma exchange therapies; except for the one with paraneoplastic syndrome associated with small cell lung cancer, the remaining 5 patients had improved modified Rankin scale (mRs) scores at discharge and received long-term immunotherapy. Two patients with SPS had gradually aggravated symptoms, and mRs scores reached 5 at the last follow-up (one for 3 years and the other one for 2 years).Conclusions:The clinical manifestations of patients with neurological syndrome associated with anti-GAD-Abs include SPS, limbic encephalitis, extralimbic encephalitis, epilepsy and cerebellar ataxia; some of these patients have paraneoplastic syndromes. Immunotherapies are effective except for these patients with paraneoplastic syndromes. Some patients with SPS tend to have a chronic course and a poor prognosis.

Objective:To summarize the clinical manifestations, neuroelectrophysiological characteristics and prognoses of Movan syndrome (MoS), and provide references for early diagnoses and prognoses.Methods:A retrospective analysis was performed. The clinical data, such as clinical symptoms, treatments and prognoses, laboratory test results and electrophysiological test results, of 13 patients with confirmed MoS in Department of Neurology, He'nan Provincial People's Hospital from January 2018 to October 2023 were collected.Results:Ten male MoS patients and 3 female ones were included. Main clinical manifestations of 13 patients with MoS included myokymia, pain, numbness of limbs, itching all over the body, hyperhidrosis, urinary and defecation disorder, tachycardia, insomnia, anxiety and depression. Ten patients completed the autoimmune encephalitis antibody detection: 3 only had positive anti-contactin-associated protein-like 2 (CASPR2) antibody, 2 only had positive anti-leucine-rich glioma-inactivated protein1 (LGI1) antibody, and 2 had both positive anti-CASPR2 antibody and anti-LGI1 antibody. Eleven patients completed tumor screening and 4 tumors (thymoma [ n=2], lung squamous cell carcinoma [ n=1] and adrenal non-Hodgkin's lymphoma [ n=1]) were noted. Ten patients completed electrocardiogram, including 3 patients with resting tachycardia and 2 patients with ST segment elevation. All patients completed the electromyographic examination; 12 patients showed abnormal motor unit potential, including myokymia potential, fasciculation potential and neuromyotonic potential; F-wave and/or M-wave post-discharge potentials were found in all patients. Follow up was performed for 1-12 months; in 9 non-tumor patients, 5 were improved in 6 patients accepted immunotherapy and one was improved in 3 patients received symptomatic treatment; in 4 tumor patients, only one was improved in 3 received immunotherapy. Conclusion:Myokymia, pain, urinary and defecation disorder, and severe insomnia are typical symptoms for MoS patients; serum anti-CASPR2/LGI1 antibody and electromyography results provide evidences for MoS diagnosis; early immunotherapy can improve the MoS prognosis, and MoS patients combined with tumors have poor clinical prognosis.

OBJECTIVE: To investigate accuracy of the currently used strategies for intraocular pressure measurements for reflecting actual 24-hour intraocular pressure fluctuations. METHODS: From September, 2018 to January, 2019, the patients with a suspected diagnosis of primary open angle glaucoma at our hospital were prospectively enrolled to receive 24-hour intraocular pressure monitoring using a Goldmann tonometer. With the intraocular pressure measurements at 0:00, 2:00, 5:00, 7:00, 8:00, 10:00, 11:00, 14:00, 16:00, 18:00, 20:00, and 22:00 as the gold standard (strategy 1), we compared the measurements taken at 5:00, 7:00, 10:00, 14:00, 18:00, and 22:00 (strategy 2) and at 8:00, 11:00, 14:00, and 16:00 (strategy 3) for their accuracy in reflecting 24-h intraocular pressure fluctuations. RESULTS: A total of 41 patients (82 eyes) were enrolled in this study. The peak intraocular pressures measured using the 3 strategies were 21.09±4.15 mmHg, 20.54±4.10 mmHg, and 19.91±4.38 mmHg, respectively, showing significant differences among them ( CONCLUSIONS For suspected cases of glaucoma, intraocular pressure measurements at 4 and 6 time points of a day can not precisely reflect the actual range of intraocular pressure fluctuations, and may lead to a missed diagnosis of glaucoma.
