Objective:To study the clinical and immunological features of two case of rare antisynthetase syndrome (ASS), so as to improve the level of diagnosis and treatment.Methods:Two cases with rare antisynthetase syndrome admitted to the First Affiliated Hospital of Zhengzhou University from July 2020 to August 2022 were collected.Results:The two rare ASS were anti-Zo antibody and anti-Ha antibody positive patients, both of which had interstitial lung disease (ILD) as the main clinical manifestation and positive anti-Ro52 antibody. Two rare antisynthetase autoantibodies manifested cytoplasmic ANA indirect immunofluorescence (IIF) staining pattern, but it is different from the cytoplasmic dense speckled pattern of several common ASS antibodies. After treatment with glucocorticoids and immunosuppressants, case 1 died of respiratory failure due to a long course of disease and late diagnosis, the lung lesions of case 2 improved significantly.Conclusion:When encountering the cytoplasmic ANA fluorescent pattern in ILD patients, especially with anti-Ro52 antibody, it is necessary to screen more myositis specific antibodies to rule out the possibility of rare ASS.

Dopamine D₃ receptor (D₃R) is implicated in multiple psychotic symptoms. Increasing the D₃R selectivity over dopamine D₂ receptor (D₂R) would facilitate the antipsychotic treatments. Herein, novel carbazole and tetrahydro-carboline derivatives were reported as D₃R selective ligands. Through a structure-based virtual screen, ZLG-25 (D₃R K_i = 685 nmol/L; D₂R K_i > 10,000 nmol/L) was identified as a novel D₃R selective bitopic ligand with a carbazole scaffold. Scaffolds hopping led to the discovery of novel D₃R-selective analogs with tetrahydro-β-carboline or tetrahydro-γ-carboline core. Further functional studies showed that most derivatives acted as hD₃R-selective antagonists. Several lead compounds could dose-dependently inhibit the MK-801-induced hyperactivity. Additional investigation revealed that 23j and 36b could decrease the apomorphine-induced climbing without cataleptic reaction. Furthermore, 36b demonstrated unusual antidepressant-like activity in the forced swimming tests and the tail suspension tests, and alleviated the MK-801-induced disruption of novel object recognition in mice. Additionally, preliminary studies confirmed the favorable PK/PD profiles, no weight gain and limited serum prolactin levels in mice. These results revealed that 36b provided potential opportunities to new antipsychotic drugs with the multiple antipsychotic-like properties.

Objective    To analyze the risk factors for acute kidney injury (AKI) after off-pump coronary artery bypass grafting (OPCABG). Methods     The PubMed, EMbase, The Cochrane Library, Web of Science, Wanfang data, CBM, VIP, CNKI were searched by computer for researches on risk factors associated with the development of AKI after OPCABG from the inception to March 2022. The meta-analysis was performed using RevMan 5.4 software. The Newcastle-Ottawa Scale (NOS) was used to evaluate the quality of included studies. Results    A total of 18 researches were included, involving 9 risk factors. The NOS score of all included studies was≥6 points. Meta-analysis results showed that age [OR=1.03, 95%CI (1.01, 1.06), P=0.020], body mass index (BMI) [OR=1.10, 95%CI (1.05, 1.15), P<0.001], history of hypertension [OR=1.45, 95%CI (1.27, 1.66), P<0.001], history of diabetes [OR=1.50, 95%CI (1.33, 1.70), P<0.001], preoperative serum creatinine level [OR=2.05, 95%CI (1.27, 3.32), P=0.003], low left ventricular ejection fraction [OR=4.51, 95%CI (1.39, 14.65), P=0.010], preoperative coronary angiography within a short period of time [OR=2.10, 95%CI (1.52, 2.91), P<0.001], perioperative implantation of intra-aortic balloon pump [OR=3.42, 95%CI (2.26, 5.16),  P<0.001], perioperative blood transfusion [OR=2.00, 95%CI (1.51, 2.65), P<0.001] were risk factors for AKI after OPCABG. Conclusion    Age, BMI, history of hypertension, history of diabetes, preoperative serum creatinine level, low left ventricular ejection fraction, preoperative coronary angiography within a short period of time, perioperative implantation of intra-aortic balloon pump, perioperative blood transfusion are risk factors for AKI after OPCABG. Medical staff should focus on monitoring the above risk factors and early identifying, in order to prevent or delay the onset of postoperative AKI and promote early recovery of patients.

Objective:To compare oxytocin combined with ergometrine with oxytocin alone in terms of primary prophylaxis for postpartum hemorrhage (PPH) at the time of cesarean section (CS).Methods:This was a multicenter double-blind randomized controlled interventional study comparing ergometrine combined with oxytocin and oxytocin alone administered at CS. From December 2018 to November 2019, a total of 298 parturients were enrolled in 16 hospitals nationwide. They were randomly divided into experimental group (ergometrine intra-myometrial injection following oxytocin intravenously; 148 cases) and control group (oxytocin intra-myometrial injection following oxytocin intravenously; 150 cases) according to 1∶1 random allocation. The following indexes were compared between the two groups: (1) main index: blood loss 2 hours (h) after delivery; (2) secondary indicators: postpartum blood loss at 6 h and 24 h, placental retention time, incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution; (3) safety indicators: nausea, vomiting, dizziness and other adverse reactions, and blood pressure at each time point of administration.Results:(1) The blood loss at 2 h after delivery in the experimental group [(402±18) ml] was less than that in the control group [(505±18) ml], and the difference was statistically significant ( P<0.05). (2) The blood loss at 6 h and 24 h after delivery in the experimental group were less than those in the control group, and the differences were statistically significant (all P<0.05). There were no significant differences between the two groups in the incidence of PPH, the proportion of additional use of uterine contraction drugs, hemostatic drugs or other hemostatic measures at 2 h and 24 h after delivery, the proportion requiring blood transfusion, and the proportion of prolonged hospital stay due to poor uterine involution (all P>0.05). (3) Adverse reactions occurred in 2 cases (1.4%, 2/148) in the experimental group and 1 case (0.7%, 1/150) in the control group. There was no significant difference between the two groups ( P>0.05). The systolic blood pressure within 2.0 h and diastolic blood pressure within 1.5 h of drug administration in the experimental group were higher than those in the control group, and the differences were statistically significant ( P<0.05), but the blood pressure of the two groups were in the normal range. Conclusion:The use of ergometrine injection in CS could reduce the amount of PPH, which is safe and feasible.

BACKGROUND: The onset and clinical presentation of systemic lupus erythematosus (SLE) are sex-related. Few studies have investigated the distinctions in clinical characteristics and treatment preferences in male and female SLE patients in the initial cohort. This study aimed to improve the understanding of Chinese SLE patients by characterizing the different sexes of SLE patients in the inception cohort. METHODS: Based on the initial patient cohort established by the Chinese SLE Treatment and Research Group, a total of 8713 patients (795 men and 7918 women) with newly diagnosed SLE were enrolled between April 2009 and March 2021. Of these, 2900 patients (347 men and 2553 women) were eligible for lupus nephritis (LN). A cross-sectional analysis of the baseline demographic characteristics, clinical manifestations, laboratory parameters, organ damage, initial treatment regimens, and renal pathology classification was performed according to sex. RESULTS: In the SLE group, as compared to female patients, male patients had a later age of onset (male vs. female: 37.0 ± 15.8 years vs. 35.1 ± 13.7 years, P  = 0.006) and a higher SLE International Collaborative Clinic/American College of Rheumatology damage index score (male vs. female: 0.47 ± 1.13 vs. 0.34 ± 0.81, P  = 0.015), LN (male vs. female: 43.6% vs. 32.2%, P < 0.001), fever (male vs. female: 18.0% vs. 14.6%, P  = 0.010), thrombocytopenia (male vs. female: 21.4% vs. 18.5%, P  = 0.050), serositis (male vs. female: 14.7% vs. 11.7%, P  = 0.013), renal damage (male vs. female: 11.1% vs. 7.4%, P < 0.001), and treatment with cyclophosphamide (CYC) (P < 0.001). The frequency of leukopenia (male vs. female: 20.5% vs. 25.4%, P  = 0.002) and arthritis (male vs. female: 22.0% vs. 29.9%, P < 0.001) was less in male patients with SLE. In LN, no differences were observed in disease duration, SLE Disease Activity Index score, renal biopsy pathological typing, or 24-h urine protein quantification among the sexes. In comparisons with female patients with LN, male patients had later onset ages (P  = 0.026), high serum creatinine (P < 0.001), higher end-stage renal failure rates (P  = 0.002), musculoskeletal damage (P  = 0.023), cardiovascular impairment (P  = 0.009), and CYC use (P  = 0.001); while leukopenia (P  = 0.017), arthritis (P  = 0.014), and mycophenolate usage (P  = 0.013) rates were lower. CONCLUSIONS Male SLE patients had more severe organ damage and a higher LN incidence compared with female SLE patients; therefore, they may require more aggressive initial treatment compared to female patients.

CONCLUSIONS ：The weighting recheck management improves the accuracy and safety of PIVAS preparation，effectively improves error detection rate ，reduces the occurrence of external error ，but prolongs the time of checking ， which are urgent to be solved by information and automation means.

Objective To investigate the prevalence of iron deficiency(ID)and iron deficiency anemia (IDA) in pregnant women in urban areas of China. Methods The study was a national cross-sectional survey conducted from September 19th, 2016 to November 20th, 2016. According to the classification of the National Bureau of Statistics, all survey sites were set up in 6 regions of the country. Pregnant women were continuously selected using multistage stratified sampling. A total of 12 403 pregnant women were collected and examined for serum ferritin and hemoglobin levels. Results The median serum ferritin level during pregnancy was 20.60 μg/L(11.78-36.98 μg/L), the hemoglobin level was(118±12)g/L. With the progress of pregnancy, the levels of serum ferritin and hemoglobin decreased gradually. The median serum ferritin levels in the first, second trimester and third trimester were 54.30 μg/L(34.48-94.01 μg/L), 28.60 μg/L(16.40-50.52 μg/L), and 16.70 μg/L(10.20-27.00 μg/L)respectively(P<0.01). The mean hemoglobin levels were(127 ± 10)g/L,(119 ± 11)g/L and(117 ± 11)g/L respectively(P<0.01). The prevalence of ID in urban pregnant women was 48.16%(5 973/12 403), and IDA prevalence was 13.87% (1 720/12 403). The prevalence of IDA in the first, second trimester and third trimester were 1.96% (20/1 019), 8.40%(293/3 487)and 17.82%(1 407/7 897), respectively(P<0.01). The prevalence of standardized ID and IDA were significantly different in various regions of China(P<0.01). The standardized prevalence of ID were relatively higher in East China and Northeast China, 57.37% and 53.41% respectively, while it was the lowest in Southwest China, 30.51%. The standardized prevalence of IDA in South Central, Northwest, and East China were relatively high, 21.30%, 16.97% and 17.53% respectively, and the standardized prevalence of IDA in Southwest China was the lowest, 5.44%,the differents in various regions were significant(all P<0.01). Conclusion The current phenomenon of ID and IDA in pregnant women is still very common,and nutrition and health care during pregnancy should be strengthened.
