BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.

Autoimmune encephalitis（AE）is a group of inflammatory disorders within the central nervous system（CNS）triggered by autoimmune mechanisms. Most AE patients show good responses to first-line immunotherapies such as corticosteroids and intravenously injected immunoglobulin. Nevertheless，the adverse effects associated with extensive immunosuppression have become a difficult issue in treatment，and some patients with severe conditions or recurrence still require further intensive therapy. Therefore，it is urgently needed to search for novel treatment strategies with high efficiency，precision，and safety. In recent years，targeted immunotherapy and chimeric antigen receptor T-cell immunotherapy that specifically target immune cells or cytokines involved in the pathogenesis of AE have gradually become research hotspots，with good tolerability and safety，which provides new options for the clinical management of AE.

A case of idiopathic hypertrophic spinal pachymeningitis is reported. The patient was a middle-aged female, with the course of disease more than 1 year. Clinical manifestations included recurrent fever,headache and backache, and the magnetic resonance imaging showed diffuse enhancement and thickening of the spinal dura mater. Dural biopsy pathology finally confirmed hypertrophic spinal pachymeningitis. After treatment with surgery and immunotherapy, the patient′s clinical symptoms improved.

Rheumatoid arthritis (RA) and myasthenia gravis (MG) are two distinct autoimmune diseases. Compared with the general population, the incidence of RA is notably higher among patients with MG. Similarly, the rate of MG in patients diagnosed with RA is also significantly increased. In this report, we presented an elderly female patient with a history usage of long-term glucocorticoid and conventional synthetic disease-modifying antirheumatic drugs (csDMARDs), whose RA symptoms remained inadequately controlled. She later exhibited drooping of the right eyelid and double vision, leading to a diagnosis of ocular myasthenia gravis (OMG). Then, we made a literature review and found that the RA patients with co-existing MG were relatively more common in middle-aged and elderly women, and most of them did not have thymoma. Thymoma wasn ' t found in our patient, which was consistent with the cli-nical characteristics of RA complicated with MG reported in previous reports. In addition, there was li-mited treatment experience in patients with both RA and MG. The treatment stratergies for RA or MG included glucocorticoids and immunosuppressants. Among the 18 patients we analyzed, 8 patients expe-rienced relief after csDMARDs, while other 8 patients received biologics or targeted DMARDs, including tumor necrosis factor inhibitors (TNFi) in 5 cases, JAK inhibitors in 2 cases, and B-cell depletion therapy (rituximab) in 2 cases. What called for special attention was that one RA patient was diagnosed with MG after using 23 months of methotrexate and 6 weeks of etanercept (TNFi), with rituximab 1 000 mg for the first time, followed by 500 mg every 6 months, and finally both RA and MG were well controlled. For the patient in this study, MG symptoms improved with increased dosage of prednisone. In order to tapper the dose of glucocorticoid, it was necessary for more potent immunosuppressant for both RA and MG. Given her history of cardiac conditions, JAK inhibitors were not considered, and due to the uncertain efficacy of TNFi, we chose to administer low-dose rituximab (100 mg). Subsequent follow-up revealed stable conditions for both RA and MG, allowing for discontinuance of glucocorticoid after 5 months. It reflected the potential efficacy and cost-effectiveness of low-dose, long-interval rituximab in treating RA patients combined with MG, while it also minimized infection risks. However, the duration for subsequent infusions remained uncertain and required further observation. In conclusion, RA combined with MG is rare. For patients exhibiting poor responses to csDMARDs, low-dose, long-interval rituximab might be a promising treatment option.

Objective:To evaluate the role of high frequency ultrasonography in diagnosis of closed volar plate injury of proximal interphalangeal joint.Methods:From May 2015 to may 2021, 41 patients with acute closed volar plate injury confirmed by Department of Hand and Foot Surgery of the Provincial Hospital Affiliated to Shandong First Medical University were examined by high frequency ultrasonography. The sonographic features were analyzed and classified.Results:High frequency ultrasonography could not only clearly show the thickness, shape and echo of volar plate, but also the degree of injury and avulsion fracture of volar plate, according to which the closed volar plate injury could be divided into three types: A, B and C. Type A(13 cases): Avulsion fracture of the middle phalangeal base was found with volar plate rupture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and avulsion fracture was found at the distal end of the volar plate. Type B(11 cases): Complete rupture of the volar plate attachment of the middle phalangeal base was found without avulsion fracture, the sonogram showed that the continuity of the volar plate attachment of the middle phalangeal base was interrupted, and the end of the volar plate contracted and thickened. Type C(17 cases): Tear of the volar plate was found, the sonogram showed enlarging volar plates, heterogeneous internal echo, and liquid dark area was visible in some cases. The average thickness of the three types of closed volar plate injury of the proximal interphalangeal joint measured by ultrasound was (0.33±0.05)cm, and the average thickness of the volar plate at the same position of the corresponding finger on the opposite side was (0.22±0.03)cm. There was significant difference between the two groups ( t=7.864, P=0.006). Conclusions:High frequency ultrasonography is the preferred imaging examination method for the diagnosis of closed volar plate injury in proximal interphalangeal joint, which has an important guiding significance for the selection of clinical treatment.

Objective: To investigate clinical characteristics of urodynamics in elderly male patients with indwelling urinary catheterization. Methods: Clinical urodynamics of 497 male patients with indwelling urinary catheterization aged 60 years and over from December 2010 to April 2019 in our center were retrospectively analyzed and divided into 3 groups: 60-69-year-old group(n=114), 70-79-year-old group(n=220), and 80-111-year-old group(n=163). According to the catheter indwelling time, the patients were divided into 3 groups: 1-2 weeks group(n=262), 2-4 weeks group(n=47)and over 4 weeks group(n=188). The cause of indwelling urinary catheterization, bladder outlet obstruction, acontractile detrusor and other indicators were observed. Results: The main cause of indwelling urinary catheterization in elderly men was acute urinary retention(55.1%, 274 cases), in that the most common diagnosis was benign prostatic hyperplasia(90.3%, 449 cases). No statistically significant difference in the different catheter indwelling time-related urodynamics between the different age groups was found(χ²=1.606, 0.199 and 2.477, all P>0.05). There were statistically significant differences both in the incidences of bladder outlet obstruction between the 1-2 weeks vs.2-4 weeks vs.over 4 weeks groups[56.9%(149/262)vs.55.3%(26/47) vs.42.6%(80/188), χ²=9.315, P<0.05)], and in the incidences of acontractile detrusor between the 1-2 weeks vs.2-4 weeks vs.over 4 weeks groups[15.6%(41/262)vs.12.8%(6/47)vs.29.8%(56/188), χ²=15.319, all P<0.05)]. There was no statistically significant difference in catheter indwelling time-related urodynamics between two groups with normal detrusor muscle function and weak detrusor muscle function(P>0.05). Clinical urodynamics had no statistically significant in different age groups(P>0.05). Conclusions Bladder outlet obstruction is the main cause of indwelling urinary catheterization in elderly men.Urodynamic examination can be performed 1-2 weeks after indwelling urinary catheterization.Age has no significant effect on the catheter indwelling time-related urodynamics.The duration of indwelling urinary catheterization has little effect on the urodynamic diagnosis in patients with normal or weak detrusor muscle contractile strength.The elderly patients may have acontractile detrusor if the duration of indwelling urinary catheterization is more than 4 weeks.

BACKGROUND AND PURPOSE: Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is the most common type of autoimmune encephalitis. This study aimed to explore the possible factors affecting the response to first-line treatments in patients with anti-NMDAR encephalitis. METHODS: We enrolled 29 patients who were diagnosed as anti-NMDAR encephalitis between January 1, 2015, and June 30, 2018. They were divided into the remission and nonremission groups according to their response to first-line treatments. The demographics, clinical manifestations, main ancillary examinations, follow-up treatments, and prognosis of patients were recorded. The symptoms reported on in this study occurred before treatments or during the course of first-line treatments. RESULTS: There were 18 patients (62.07%) in the remission group and 11 patients (37.93%) in the nonremission group. Compared to the remission group, a higher proportion of the patients in the nonremission group exhibited involuntary movements, decreased consciousness, central hypoventilation, lung infection, and hypoalbuminemia. The nonremission group had a high incidence of increased intracranial pressure and significant elevations of the neutrophil-to-lymphocyte ratio in peripheral blood (NLR), aspartate aminotransferase, and fibrinogen. Six patients (54.55%) in the nonremission group received second-line immunotherapy. Only one patient (3.45%) died, which was due to multiple-organ failure. CONCLUSIONS: Anti-NMDAR-encephalitis patients with more symptoms—especially involuntary movements, disturbance of consciousness, central hypoventilation, and accompanying hypoalbuminemia and pulmonary infection—may respond poorly to first-line treatments. Positive second-line immunotherapy therefore needs to be considered. Admission to an intensive-care unit, increased cerebrospinal fluid pressure, and increased NLR might be the significant factors affecting the response to first-line treatments.

Transient central nervous system symptoms and reversible white matter lesions have been rarely reported in X-linked Charcot-Marie-Tooth disease type 1.We reported two cases of X-linked CharcotMarie-Tooth disease type 1 associated with reversible white matter lesions.Patient 1 is a 15-year old boy who presented with paroxysmal speech disorders and limb weakness at the beginning of the illness.He still walked unsteadily after discharge.Patient 2 is a 13-year old girl with transient numbness and weakness in her left extremities and slurred speech.She completely recovered.Both of them presented pes cavus without obvious family history or personal history.Both of them showed primary symptom of central nervous system with MRI abnormal findings in corpus callosum and periventricular areas.The electrophysiological studies showed a mixed demyelinating and axonal sensorimotor neuropathy in patient 1 but no significant abnormalities in patient 2.The genetic analysis of both patients showed a pathogenic mutation in GJB1 gene.Clinicians should improve the recognition of X-linked Charcot-Marie-Tooth disease type 1.This type of disorders can behave as symptoms of nervous system firstly even if there is no other typical characteristics,such as peripheral nervous system involvement.

The severe fever with thrombocytopenia syndrome virus (SFTSV),a new RNA virus,was discovered in recent years,which can lead to fever,thrombocytopenia and multiple organ dysfunction.Picks is the main media A case of a SFTSV-related encephalitis diagnosed by second-generation gene sequencing was reported here.The patient had fever,disturbance of consciousness,convulsions,with thrombocytopenia and enzymatic indicators increased significantly.After active anti-virus and supportive treatment,the prognosis was good.It is our aim to suggest that,in the epidemic season,when you meet thesimilar patients like this,you should consider the possibility of SFTSV-related encephalitis.Virus nucleic acid detection and second-generation gene sequencing technology are helpful for timely diagnosis and treatment and reducing mortality of the disease.

Objective To analyze the role of telehealth?based dialysis registration systems in real?time and dynamic reflection of renal anemia in hemodialysis (HD) patients, and discuss the prospect of its application in dialysis registration management. Methods The Red China project was to build up a dialysis registration system based on the WeChat mobile terminal platform. Demographic and baseline laboratory parameters such as age, gender, primary disease, dialysis age, creatinine were recorded in this system. Hemoglobin (Hb) level was monthly recorded. The platform generated Hb statistics report for each HD center monthly, including the detection rate, target rate and the distribution level of Hb, and released it to physicians through the WeChat terminal of mobile phone. After that, physicians could change the treatment of anemia individually on basis of this report. Here the demographic and baseline laboratory parameters, the detection rate, target rate, the average level and the distribution of Hb from June 2015 to October 2017 after the project launched were analyzed. Results From June 2015 to October 2017, 8392 maintenance HD patients from 28 HD centers in Shanghai were enrolled, of whom 5059(60.3％) were male.The average rate age was (60.5 ± 13.7) years old. Baseline average Hb was (108.3±16.0) g/L. Baseline detection rate and target rate were 54.2％and 47.5％, respectively. After 28 months follow?up, the detection rate of Hb increased from 54.2％ to 73.6％ (P<0.001), the target rate of Hb increased from 47.5％ to 56.1％ (P<0.001), and the level of average Hb rose from (108.3±16.0) g/L to (110.7±16.0) g/L. The difference between average Hb in two consecutive months was less than 1.3 g/L. Conclusions The telehealth?based dialysis registration system can timely report the anemia situation of HD patients, which may improve the awareness rate of anemia, the degree of attention and the compliance of anemia monitoring, so as to improve the detection rate and target rate of Hb and reduce the fluctuation of Hb, which helps to maintain the HD patients to correct anemia in a timely, stable and long?term way. The telehealth?based dialysis registration system, as an improved mode of dialysis registration is a promising way for long?term management of renal anemia in dialysis patients.
