Analysis of Diagnostic Value of Electrogastrography for Parkinson's Disease and its Predictive Value for the Disease Progression.
The study aimed to evaluate the diagnostic and prognostic value of indexes detected by electrogastrography in Parkinson's disease patients. One hundred twenty early Parkinson's disease patients and 120 healthy controls were recruited, and underwent electrogastrography to detect dominant frequency (DF), instability coefficient of DF (ICDF), low frequency range (LFR), high frequency range (HFR), and normal frequency range (NFR). The receiver operating characteristic (ROC) curve was drawn for the diagnostic value analysis. ⋯ Preprandial ICDF value and TDI score had the ability to distinguish Parkinson's disease patients with the AUC of 0.874 and 0.859 respectively. The ICDF detected by electrogastrography has high clinical value in the early diagnosis of Parkinson's disease, and the combination of ICDF and TDI can improve the diagnostic sensitivity and specificity of a single indicator. High ICDF levels during the preprandial phase are related to the poor prognosis of Parkinson's disease patients after treatment.

Review Case ReportsTelitacicept for Recalcitrant Cutaneous Manifestations of Systemic Lupus Erythematosus: A Case Report and Review of the Literature.
Telitacicept is a novel humanized, recombinant transmembrane activator and calcium modulator and cyclophilin ligand interactor and the Fc portion (TACI-Fc) fusion protein, designed to neutralize the activity of both B-cell lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL). On March 9, 2021, telitacicept received its first approval in China for the treatment of adult patients with active, autoantibody-positive systemic lupus erythematosus (SLE). Additionally, on April 15, 2020, the U. ⋯ This is the first case that reports telitacicept successfully treated a SLE patient with refractory cutaneous involvement, which provides a potential therapeutic option for recalcitrant cutaneous manifestations of SLE. Furthermore, we review reported studies of BLyS targeted treatments for mucocutaneous lupus. Telitacicept appears to have activity in refractory cutaneous involvement of SLE and clinical trials are warranted to further assess this potential therapy.

Case ReportsSjögren's Syndrome Presenting with Temporary Hemiplegia Mimicking Transient Ischemic Attack.
Sjögren's syndrome manifests with a wide variety of neurologic symptoms. This case report presents a 53-year-old woman with Sjögren's syndrome associated with temporal hemiplegia, which was suspected to be a transient ischemic attack. After induction of immunosuppressive therapies [high-dose prednisolone (1 mg/kg/day) and intravenous cyclophosphamide (total 5 g)], the hemiplegia did not reappear and the blood flow abnormalities remarkably improved as depicted on electroencephalography and single photon emission computed tomography. This case suggests that temporal hemiplegia presenting with transient ischemia-like attack symptoms may be a neurologic manifestation of Sjögren's syndrome and responsive to immunosuppressive therapy.

Decreased Fertility in Women with Cesarean Scar Syndrome Is Associated with Chronic Inflammation in the Uterine Cavity.
Chronic inflammation in cesarean scar defect contributes to secondary infertility in women with cesarean scar syndrom; however, it remains unclear about the situation of inflammation in uterine cavity in women with cesarean scar syndrome. This ambidirectional cohort study aimed to explore the effect of inflammation in the uterine cavities of women with cesarean scar syndrome on infertility at a single university hospital. The frequency of chronic endometritis in infertile patients was retrospectively compared between the cesarean scar syndrome group and non-cesarean scar syndrome group. ⋯ Endometriosis was detected in 51 (70%) patients with laparoscopy. Tumor necrosis factor-α and interleukin-1β levels in the cesarean scar syndrome group were significantly higher than those in the control group (p = 0.0002 and p = 0.0217, respectively). Our findings suggest that one cause of secondary infertility in women with cesarean scar syndrome is embryo implantation failure-associated chronic endometritis, endometriosis, and chronic inflammation in the uterine cavity.

Total Glucosides of Paeony Attenuates Ulcerative Colitis via Inhibiting TLR4/NF-κB Signaling Pathway.
The therapeutic effects and mechanisms of action of total glucosides of paeony (TGP) in treating ulcerative colitis remain to be clarified. Mouse model of ulcerative colitis was treated with TGP and the indexes including scores of disease activity index, gross morphologic damage and histological damage, and inflammatory and oxidative stress markers were determined. Patients with ulcerative colitis received TGP capsule therapy and the indexes including efficacy of colonoscopy and histology, scores of Ulcerative Colitis Activity Index (UCAI) and Short Inflammatory Bowel Disease Questionnaire (SIBDQ), and inflammatory parameters were assessed. ⋯ The overall response rate of TGP capsule was significantly higher than that of routine therapy. TGP treatment significantly suppressed the expressions of TLR4 and NF-κB in colonic tissues of both mouse model and patients with UC. TGP shows a good therapeutic effect on ulcerative colitis in animals and human patients, and the underlying mechanisms may be related to the inhibition of TLR4/NF-κB signaling by TGP.
