In this review, we summarize up-to-date findings on the usefulness of A2AR antagonists and GLP1R agonists in PD management. We explain the molecular mechanisms of these medications and their interactions with other neurotransmitter receptors. Furthermore, we discuss the efficacy and limitations of A2AR antagonists and GLP1R agonists in clinical practice.
The three major gynecologic cancers are cervical, endometrial, and ovarian cancer. This study aimed to describe the 19-year trends and survival rates in cervical, endometrial, and ovarian cancer in a Korean female population.

We searched the Korea Central Cancer Registry to identify patients with gynecologic cancer between 1999 and 2017. Age-standardized rates and annual percent changes were calculated. The relative survival rate (RSR) was reported by histology, age, and stage for each gynecological cancer.

The total number of cervical, endometrial, primary peritoneal, ovarian epithelial, fallopian tube (POFT) cancer was 134,863, with the number of cases increasing every year 6,077 in 1999 to 8,011 in 2017. click here The incidence of cervical cancer has decreased; however, that of POFT and endometrial cancer has increased. The 5-year RSR of cervical, POFT, and endometrial cancer was reported to be 80.8%, 61.4%, and 88.1%, respectively. In the case of cervical cancer, squamous cell carcinoma showed better survival than other histology (82.8% vs. 73.5%). Furthermore, in the case of endometrial cancer, endometrioid histology had substantially better 5-year RSR than the others (93.2% vs. 76.5%). Contrastingly, in the case of ovarian cancer, serous carcinoma had worse 5-year RSR than other types of histology.

The incidence rates for gynecologic cancers increased from 2005 to 2017, with an annual increase of 2.76 per year until 2017. Endometrial cancer had the highest RSR, while ovarian cancer had the lowest. Active cancer screening and the introduction of effective treatments might have contributed to the improved RSRs of gynecologic cancers.

Methods A CRKP (designated K. pneumoniae C35) was isolated from a stool sample. The minimal inhibitory concentrations of antimicrobial agents were determined using the broth microdilution method. Whole-genome sequencing and genome analysis were performed to identify the antibiotic resistance and virulence genes. The genetic relationship among K. pneumoniae C35 and other CRKP isolates from our hospital was analyzed by single nucleotide polymorphism (SNP) typing of core genomes. Conjugation experiments were carried out by filter mating to evaluate the transferability and efficiency of resistance genes. The virulence phenotype was determined by Galleria mellonella infection model. Results K. pneumoniae C35 exhibited resistance to the majority of tested antibiotics, especially carbapenems, sulbactam, and polymyxins. SNP typing showed that K. pneumoniae C35 shared a high degree of sequence homo CR-hvKP. The emergence of such strain should be alerted and active surveillance is warranted.Objective To establish a nomogram model for hematoma expansion (HE) prediction after intracerebral hemorrhage (ICH) and evaluate its performance in a multidimensionally way. Methods A total of 348 ICH patients who were firstly diagnosed and hospitalized in the Second Affiliated Hospital of Soochow University from January 2017 to December 2019 were collected retrospectively. There were 236 males and 112 females, and their age ranged from 18 to 94 (62.0±14.6) years. All patients were divided into HE group (n=121) or non-HE group (n=227) according to the presence or absence of HE. The clinical and imaging features were compared between the two groups. Multivariate logistic regression analysis was performed for determining the independent predicting factors for HE prediction and a Nomogram model was established by using these factors. Receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis (DCA) were used to evaluate the prediction effectiveness, accuracy and clinical practicch demonstrated that the model has an ideal prediction effectiveness. The calibration curve showed that the prediction probability of HE of the model fits well with the actual probability, and with high calibration. DCA showed relatively wide range of optional threshold probability of the model (ranging from 14% to 72%), the clinical practicability of this model was high. The internal validation results showed a C-index of 0.703, indicated a good discrimination power. Conclusion The established Nomogram model can predict the HE of ICH with good prediction effectiveness, discrimination power and with good clinical practicability, which can be capable of providing an intuitive and visual guidance tool for timely identifying ICH patients who may have HE.Objective To establish the standard operation procedure (SOP) for detection of oligoclonal band (OCB) in cerebrospinal fluid (CSF) and verify consistency by using this SOP in different laboratories. Methods The SOP for detection of CSF-OCB fluid was successfully established by an expert feedback approach. Neuroimmunology laboratories in 3 representative Chinese three-tier research hospitals were selected for this study, and commercially available protein electrophoresis automation systems and detection SOP were set up. The quality control product was provided by the College of American Pathologists (CAP) and Sebiacompany were used for interior quality and compared to each other, respectively. Seventeen serum and CSF paired samples were tested and compared using the same SOP. Kappa test or Kendall W test were adopted to evaluate the inter-laboratory consistency among different hospitals. Results The results of repeated testings in a single hospital suggested that the 2-and 4-fold dilution for CSF-OCB were reported as positive, while 64-and 128-fold dilution were reported as negative. Positive or negative inconsistencies were reported in 8-, 16-, and 32-fold dilution. After increasing the number of repetitions, the results showed that both 16-and 32-fold dilution were reported as negative, and 8-fold dilution exhibited negative results (2 positive results for 40 repetitions, coincidence rate=95%).The results of multi-center inter-laboratory quality assessment showed that the detection consistency rate among 3 hospitals was 100% (Kappa value =1). Conclusions The SOP to detect CSF-OCB established in this study demonstrates a good repeatability and stability. Therefore,such SOP would be a good reference for diagnostic laboratories to detect CSF-OCB in China.Objective To quantitatively analyze the reticulin fiber intensity density (RFD) in patients with myelodysplastic syndrome (MDS) by using the computer-aided grid point method, and preliminarily explore its correlation with the prognosis of MDS patients. Methods Bone marrow (BM) slices from 32 primary MDS patients treated in Tongren Hospital Shanghai Jiao Tong University School of Medicine from February 2017 to December 2019 were observed. Images were taken by the optical microscope imaging system after the Gomori staining. The computer grid marking software was developed according to the principle of the mesh micrometer to assess RFD, meanwhile, the artificial semi-quantitative were used to assess the fibrosis of bone marrow. The co-relation between the above two methods was evaluated, and the relationship between RFD and prognosis of MDS patients were further investigated with Cox regression analysis. Results Of the patients, there were 17 males and 15 females with a median age of 69 years (32-91 years). The RFD quantitatively analyzed by the computer-based method was positively correlated with the myelofibrosis grade by the artificial semi-quantitative analysis (r=0.497, P=0.004). The RFD in patients diagnosed with MDS complicated with excess blasts (MDS-EB) was significantly higher than that in the non-MDS-EB group((9.55%±0.75%) vs (1.71%±0.23%), P9.81% was significantly shorter than that in patients with RFD≤9.81% (P=0.003). Conclusion Abnormal proliferative fibrosis of bone marrow is a potential high-risk factor for poor prognosis of MDS patients.Objective To analyze the clinical manifestations and gene mutations of patients with Alagille Syndrome (ALGS) to improve diagnosis and provide a boarder spectrum of gene mutagenesis. Methods A retrospective study was performed in 18 ALGS patients admitted to Xi'an Children's Hospital from January 2016 to January 2020. Clinical characteristics, biochemical parameters, gene mutations and prognosis were collected and analyzed. Next-generation sequencing of liver disease-related gene panels or the whole exome was carried out for the probands. Mutations of candidate genes were verified by Sanger sequencing in their family members. Based on the comparison with a well-known database of disease, the harmfulness and structures of proteins with novel mutations were predicted, and the pathogenicity was evaluated. Results There were 9 males and 9 females with ALGS in this study, and the age of initial diagnosis was 2.5 (1.9, 6.8) months. All patients initially presented with cholestasis, with other symptoms including 15 help diagnosis. The JAG1 and NOTCH2 genes showed a wide array of mutations, with many novel mutations identified in this study.Objective To investigate the diagnostic value of serum lipoprotein associated phospholipase A2 (Lp-PLA2), amyloid A (SAA) and immunoglobulin E (IgE) in patients with type 2 diabetes (T2DM) mellitus complicated with atherosclerotic disease. Methods From June to December 2019, 224 patients with T2DM in the Second Hospital of Lanzhou University were selected, including 144 males and 80 females, aged (61±11) years. According to the results of imaging examination, the patients were divided into T2DM with AS group (T2DM-AS group, n=160) and T2DM group (n=64); Healthy subjects in the same period were selected as healthy control group (n=160). Lp-PLA2, IgE, SAA, hs-CRP, TC, TG, HDL-C, LDL-C and Hcy were detected in all patients and healthy controls. The correlation between the above indexes, gender, age and T2DM with AS was analyzed; Multivariate logistic regression was used to analyze the risk factors of T2DM with AS. Results Compared with the healthy control group, the levels of IgE and Lp-PLA2 in T2DM-AS group ande diagnostic efficiency of T2DM patients with AS.Objective To investigate the characteristics of low frequency repetitive nerve stimulation (RNS) in patients with myasthenia gravis (MG) and analyze the correlation between RNS results and clinical characteristics. Methods The clinical and electrophysiological data of 107 MG patients who were admitted to Guangdong Provincial People's Hospital and underwent electromyography (EMG) between September 2015 to September 2020 were retrospectively reviewed. The characteristics of low frequency RNS in ocular MG and generalized MG patients were analyzed. Patients were divided into RNS-negative group and RNS-positive group according to the RNS results. The clinical features, serological and thymic CT findings, thymic pathology were collected and compared. Binary logistic regression analysis was used to analyze the related factors of low frequency RNS. Results Generalized MG (73.0%, 46/63) showed a lower positive rate of low frequency RNS compared to ocular MG (34.1%, 15/44) (P less then 0.001). In generalized MG, the positive rate of low frequency RNS in accessory nerve (68.
