ObjectiveTo analyze the trend and influencing factors of low birth weight (LBW) among newborns in Chongming District of Shanghai from 2008 to 2022, so as to provide references for the development of intervention measures reducing the rate of LBW. MethodsBirth surveillance data of Chongming District of Shanghai from 2008 to 2022 were collected and organized, and the annual percentage change (APC) of LBW was calculated by using Joinpoint 5.0.2 software for trend change analysis. Logistic regression analysis was used to analyze the influencing factors of LBW. ResultsThe overall incidence of LBW was 3.71% in Chongming District, Shanghai from 2008 to 2022. Joinpoint trend analysis showed that the incidence of LBW in Chongming District had an upward trend (APC=5.49%, 95%CI: 3.31%‒7.72%, P<0.001).Multivariate logistic regression analysis showed that preterm birth, multiple births, female infants, birth defects, first pregnancy, primiparity, and a young father age (<20 years) were risk factors for LBW in Chongming District. Among the term infants, female infants, birth defects, and first pregnancy were risk factors for LBW (P<0.05). Female infants, birth defects, first pregnancy, primiparity, advanced maternal age (≥35 years), and a young father age (<20 years) were risk factors in singleton neonates. ConclusionThe incidence of LBW among newborns is on the rise in Chongming District of Shanghai. Therefore, high risk groups need to be identified, and prenatal check-ups and pregnancy care should be strengthened to reduce the risk of neonatal LBW.

Objective To analyze the prognosis and influencing factors of patients with acute myocardial infarction(AMI)complicated with cardiogenic shock(CS)under extracorporeal membrane oxygenation(ECMO)support.Methods Retrospective analysis of the clinical data of ECMO supported coronary angiography and percutaneous coronary intervention(PCI)treatment for AMI complicated with CS patients who visited the department of emergency medicine of the Second Hospital of Hebei Medical University from December 2018 to December 2021,including gender,age,body mass index(BMI),past history(smoking history,coronary heart disease,diabetes,hypertension,hyperlipidemia,cerebrovascular disease),acute physiological and chronic health evaluationⅡ(APACHEⅡ),vasoactive-inotropic score(VIS),the worst auxiliary examination indicators within 24 hours before ECMO[arterial lactate acid,white blood cell count(WBC),cardiac troponin I(cTnI),alanine transferase(ALT),total bilirubin(TBil),creatinine(Cr),serum potassium(K+),left ventricular ejection fraction(LVEF)],time from onset to PCI,coronary angiography results(involved anterior descending branch,circumflex branch,right coronary artery,three-vessel lesions,left main artery lesions),whether to use intra aortic-balloon counterpulsation(IABP)and continuous renal replacement therapy(CRRT).Patients were divided into survival and death groups based on the prognosis after 30 days of onset.Univariate analysis was used to compare the differences in the above indicators between the two groups with different prognoses,Logistic regression analysis was used to analyze the independent risk factors affecting the prognosis of AMI patients with CS under ECMO support coronary angiography and PCI treatment,and the receiver operator characteristic curve(ROC curve)was drawn to evaluate the predictive value of risk factors on patient prognosis.Results Out of 39 patients,21 cases(53.8%)survived and 18 cases(46.2%)died.Compared with the survival group,the VIS score,lactate acid,time from onset to PCI,involvement of the circumflex artery,three-vessel disease,and left main artery lesions significantly increased in the death group(all P＜0.05).Logistic regression analysis showed that lactate acid and three-vessel lesions were independent risk factors affecting the 30-day prognosis of AMI patients with CS[odds ratio(OR)and 95%confidence interval(95%CI)were 1.845(1.018-3.342)and 107.171(1.307-8 785.901),all P＜0.05].ROC curve analysis showed that lactate acid and three-vessel lesions has predictive value for the prognosis of AMI combined with CS patients undergoing ECMO supported coronary angiography and PCI treatment,the area under the ROC curve(AUC)were 0.756 and 0.752,95%CI were 0.601-0.911 and 0.588-0.916,P value were 0.007 and 0.008.When the cut-off value of lactic acid was 5 mmol/L,the sensitivity and specificity of predicting the prognosis of AMI combined with CS patients undergoing coronary angiography and PCI treatment were 94.1%and 57.1%,respectively.Conclusions The indications for using ECMO in critically ill patients with AMI combined with CS need to be further refined.VIS score,lactate acid,time from onset to PCI,three-vessel lesions,and left main artery lesions are risk factors for patient death.When using ECMO support for high lactate,high VIS score,and three-vessel lesions,caution should be exercised.Early ECMO support can improve the prognosis of appropriate patients by reducing lactate,reducing the use of vasoactive drugs,and shortening the time from onset to PCI.

Objective:To explore the therapeutic characteristics of population with gout achieving treat-to-target (T2T) indicators through real-world research and evaluate their safety.Methods:A total of 3 287 patients diagnosed with gout by rheumatologists in 21 first-class tertiary hospitals in 10 provinces, municipalities, and autonomous regions in China from January 2015 to December 2021 were included in this polycentric cross-sectional study. The database included patients′ general information, disease characteristics, and clinical application of traditional Chinese and Western medicine treatment measures. SPSS and Excel software were used for data analysis. Frequency analysis, cluster analysis, and factor analysis were used to summarize the characteristics and rules of treatment measures for patients with gout who achieved the target after treatment. The occurrence of adverse events (AE) was recorded during treatment.Results:After treatment, 691 visits (7%) achieved the serum urate (SUA) target, and the most frequent use of urate-lowering therapy (ULT) was febuxostat, followed by benzbromarone. The most common treatment options were following: GroupⅠ: traditional Chinese medicine (TCM) decoction-TCM external treatment-physical exercise-proprietary Chinese medicine; GroupⅡ: ferulic acid-nonsteroidal anti-inflammatory drugs (NSAIDs); Group Ⅲ: allopurinol-sodium bicarbonate-benzbromarone; Group Ⅳ: glucocorticoid-colchicine; Group Ⅴ: febuxostat. A total of 5 898 visits (60%) chieved manifestations of joint pain VAS scores target, and the most frequently used drug to control joint symptoms was NSAIDs. The frequency of use of drugs to control joint symptoms were 2 118 times (usage rate reached 35.9%), while the frequency of ULT were 2 504 times (usage rate reached 42.5%), which was higher than the joint symptom control drug. The most common treatment options were following: Group Ⅰ: proprietary Chinese medicine-TCM decoction-TCM external treatment-physical exercise; Group Ⅱ: NSAIDs-colchicine hormones; Group Ⅲ: allopurinol, Group Ⅳ: benzbromarone; Group Ⅴ: febuxostat. A total of 59 adverse events occurred during treatment.Conclusion:The proportions of gout patients who reach target serum urate level & good control of joint symptoms are both very low, and ULT and anti-inflammatory prescription patterns are very different from international guidelines, so it is necessary to strengthen the standardized management of gout patients. At the same time, life intervention measures account for a certain proportion of the treatment plans for the T2T population, and further exploration is needed.

Objective:In general, patients with seropositive rheumatoid arthritis (RA) are considered to show an aggressive disease course. However, the relationship between the two subgroups in disease severity is controversial. Our study is aimed to compare the clinical characteristics and prognosis of double-seropositive and seronegative RA in China through a real-world large scale study.Methods:RA patients who met the 1987 American College of Rheumatology (ACR) classification criteria or the 2010 ACR/European Anti-Rheumatism Alliance RA classification criteria, and who attended the 10 hospitals across the country from September 2015 to January 2020, were enrolled. According to the serological status, patients were divided into 4 subgroups [rheumatoid factor (RF)(-) anti-cyclic citrullinated peptide (CCP) antibody (-), RF(+), RF(+) anti-CCP antibody(+), anti-CCP antibody(+)] and compared the disease characteristics and treatment response. One-way analysis of variance was used for measurement data that conformed to normal distribution, Kruskal-Wallis H test was used for measurement data that did not conform to normal distribution; paired t test was used for comparison before and after treatment within the group if the data was normally distributed else paired rank sum test was used; χ2 test was used for count data. Results:① A total of 2 461 patients were included, including 1 813 RF(+) anti-CCP antibody(+) patients (73.67%), 129 RF(+) patients (5.24%), 245 RF(-) anti-CCP antibody(-) patients (9.96%), 74 anti-CCP antibody(+) patients (11.13%). ② Regardless of the CCP status, RF(+) patients had an early age of onset [RF(-) anti-CCP antibody(-) (51±14) years old, anti-CCP antibody(+) (50±15) years old, RF(+) anti-CCP antibody(+) (48±14) years old, RF(+)(48±13) years old, F=3.003, P=0.029], longer disease duration [RF(-) anti-CCP antibody(-) 50 (20, 126) months, anti-CCP antibody(+) 60(24, 150) months, RF(+) anti-CCP antibody(+) 89(35, 179) months, RF(+) 83(25, 160) months, H=22.001, P<0.01], more joint swelling counts (SJC) [RF(-) anti-CCP antibody(-) 2(0, 6), Anti-CCP antibody(+) 2(0, 5), RF(+) anti-CCP antibody(+) 2(0, 7), RF(+) 2(0, 6), H=8.939, P=0.03] and tender joint counts (TJC) [RF(-) anti-CCP antibody(-) 3(0, 8), anti-CCP antibody(+) 2(0, 6), RF(+) anti-CCP antibody(+) 3(1, 9), RF(+) 2(0, 8), H=11.341, P=0.01] and the morning stiff time was longer [RF(-) anti-CCP antibody(-) 30(0, 60) min, anti-CCP antibody(+) 20(0, 60) min, RF(+) anti-CCP antibody(+) 30(10, 60) min, RF(+) 30(10, 60) min, H=13.32, P<0.01]; ESR [RF(-) anti-CCP antibody(-) 17(9, 38) mm/1 h, anti-CCP antibody(+) 20(10, 35) mm/1 h, RF(+) anti-CCP antibody(+) 26(14, 45) mm/1 h, RF(+) 28(14, 50) mm/1 h, H=37.084, P<0.01] and CRP [RF(-) anti-CCP antibody(-) 2.3 (0.8, 15.9) mm/L, Anti-CCP antibody(+) 2.7(0.7, 12.1) mm/L, RF(+) anti-CCP antibody(+) 5.2(1.3, 17.2) mm/L, RF (+) 5.2(0.9, 16.2) mm/L, H=22.141, P<0.01] of the RF(+)patients were significantly higher than RF(-) patients, and RF(+) patients had higher disease severity(DAS28-ESR) [RF(-) anti-CCP antibody(-) (4.0±1.8), anti-CCP antibody(+) (3.8±1.6), RF(+) anti-CCP antibody(+) (4.3±1.8), RF(+) (4.1±1.7), F=7.269, P<0.01]. ③ The RF(+) anti-CCP antibody(+) patients were divided into 4 subgroups, and it was found that RF-H anti-CCP antibody-L patients had higher disease severity [RF-H anti-CCP antibody-H 4.3(2.9, 5.6), RF-L anti-CCP antibody-L 4.5(3.0, 5.7), RF-H anti-CCP antibody-L 4.9(3.1, 6.2), RF-L anti-CCP antibody-H 2.8(1.8, 3.9), H=20.374, P<0.01]. ④ After 3-month follow up, the clinical characteristics of the four groups were improved, but there was no significant difference in the improvement of the four groups, indicating that the RF and anti-CCP antibody status did not affect the remission within 3 months. Conclusion:Among RA patients, the disease activity of RA patients is closely related to RF and the RF(+) patients have more severe disease than RF(-) patients. Patients with higher RF titer also have more severe disease than that of patients with low RF titer. After 3 months of medication treatment, the antibody status does not affect the disease remission rate.

Objective:To investigate the value of quick sequential organ failure assessment (qSOFA) score in early identification for sepsis patients of different ages.Methods:A retrospective study was conducted. The clinical data of 1 529 patients with suspected infection in emergency department of Changshu No.2 People's Hospital from September 2017 to March 2020 were collected. All patients were assessed for qSOFA score, and the diagnosis and treatment were recorded. Sepsis-3 was defined as the diagnostic criteria for sepsis. All the patients were divided into five groups according to age, youth group (< 45 years old), middle-aged group (45-59 years old), presenile group (60-74 years old), elderly group (75-89 years old), and longevity group (≥90 years old). The patients' examination results, diagnosis and treatment status were collected. The distribution of different scores of qSOFA was analyzed to calculate the sensitivity, specificity, positive predictive value and negative predictive value of different qSOFA scores for the diagnosis of sepsis in patients with suspected infection of different ages. The receiver operator characteristic curve (ROC curve) was drawn to analyze the diagnostic value of qSOFA score for sepsis in patients with suspected infection at different ages.Results:Of 1 529 suspected infection patients, there were 67 patients in youth group, 129 patients in middle-aged group, 465 patients in presenile group, 778 patients in elderly group and 90 patients in longevity group. There were significant differences in lactic acid (Lac), total bilirubin (TBil), creatinine (Cr), qSOFA score and the increased value of SOFA score compared with the basic value (ΔSOFA) among the suspected infection patients at different ages. Among suspected infection patients at different ages, the patients with qSOFA score ≥ 1 were the most, and the proportion of sepsis patients was larger. Further analysis showed that qSOFA score ≥1 had a high diagnostic sensitivity in patients with suspected infection at different ages. In the youth group, the sensitivity was 84.4%, and the specificity was the highest (74.3%). Although qSOFA score ≥ 2 had a high specificity in the diagnosis of sepsis (all > 97%), its sensitivity was very low (all < 44%). In this study, all patients with a qSOFA score of 3 were sepsis, and the positive predictive value of the diagnosis of sepsis in each group was 100%. ROC curve analysis showed that the area under ROC curve (AUC) of qSOFA score for the diagnosis of sepsis in all suspected infection patients was 0.771 [95% confidence interval (95% CI) was 0.747-0.794], when the best cut-off value was 0.5, the sensitivity was 93.4% and the specificity was 45.6%. Among suspected infection patients of all ages, the accuracy of qSOFA score in the diagnosis of sepsis in the youth group and the longevity group was relatively high, with AUC (95% CI) of 0.825 (0.724-0.927) and 0.837 (0.756-0.917), respectively; when the best cut-off value was 0.5, the sensitivity was 84.4% or 92.2%, and the specificity was 74.3% or 56.4%, respectively. Conclusions:qSOFA score has an early diagnosis value for sepsis, especially in the patients aged < 45 years old or ≥ 90 years old. Using qSOFA score ≥2 to screen patients with suspected infection is likely to cause missed diagnosis.

Objective: To investigate the guiding significance of Daping orthopedics operative risk scoring system for senile patient (DORSSSP) for stratified treatment of elderly patients with severe hip fractures. Methods: A retrospectively case-control study was performed for data of 440 elderly patients with hip fracture admitted to Second Affiliated Hospital of Soochow University from January 2014 to January 2018, including 130 male and 310 female patients aged 60-98 years [(79.3±6.3)years]. According to the DORSSSP scoring system, the patients were divided into low risk group (Group A, n=208), medium risk group (Group B, n=157) and high risk group without SICU transfer after operation (Group C, n=23) and high risk group with SICU transfer after operation (Group D, n=52). The risk prediction results of each group were recorded and compared with the actual complications and mortality. Results: (1)According to the prediction of DORSSSP, the number of postoperative complications in Groups A, B, C and D were 52, 60, 14 and 31, respectively, while the number of actual complications after operation was 45, 55, 13 and 16. There was significant difference between the predicted value and the actual value of postoperative complications in Group D (P<0.01), which was not found in other three groups (P>0.05). The incidence of postoperative complications in Group D was lower than that in Group C (P<0.05). (2) According to the prediction of DORSSSP, the number of postoperative death in Groups A, B, C and D were 0, three, two and four, respectively, while the number of actual death after operation was 0, one, two and one, respectively. The predicted value and the actual value of death were significantly different in Group D (P<0.05), but were not in other three groups (P>0.05). The incidence of postoperative death in Group D was lower than that in Group C (P>0.05). Conclusions There is a good correlation between DORSSSP score and postoperative complications and mortality. Based on DORSSSP score for stratified treatment, the interventional treatment of elderly patients with severe hip fracture after operation into SICU can better reduce the incidence of complications.

Purpose: RIOK1 has been proved to play an important role in cancer cell proliferation and migration in various types of cancers—such as colorectal and gastric cancers. However, the expression of RIOK1 in breast cancer (BC) and the relationship between RIOK1 expression and the development of BC are not well characterized. In this study, we assessed the expression of RIOK1 in BC and evaluated the mechanisms underlying its biological function in this disease context. Materials and Methods: We used immunohistochemistry, western blot and quantitative real-time polymerase chain reaction to evaluate the expression of RIOK1 in BC patients. Then, knockdown or overexpression of RIOK1 were used to evaluate the effect on BC cells in vitro and in vivo. Finally, we predicted miR-204-5p could be a potential regulator of RIOK1. Results: We found that the expression levels of RIOK1 were significantly higher in hormone receptor (HR)–negative BC patients and was associated with tumor grades (p=0.010) and p53 expression (p=0.008) and survival duration (p=0.011). Kaplan-Meier analysis suggested a tendency for the poor prognosis. In vitro, knockdown of RIOK1 could inhibit proliferation, invasion, and induced apoptosis in HR-negative BC cells and inhibited tumorigenesis in vivo, while overexpression of RIOK1 promoted HR-positive tumor progression. MiR-204-5p could regulate RIOK1 expression and be involved in BC progression. Conclusion These findings indicate that RIOK1 expression could be a biomarker of HR-negative BC, and it may serve as an effective prognostic indicator and promote BC progression.

Objective To measure the expression of protein kinase D1 (PKD1),tyr463-phosphorylaed PKD1 (pPKD1-tyr463) and ser916-phos-phorylaed PKD1 (pPKD1-ser916) in squamous cell carcinoma (SCC),Bowen's disease (BD) and actinic keratosis (AK),and to explore their significance.Methods Fresh tissue samples were resected from lesions of patients with SCC (SCC group),BD (BD group) and AK (AK group),as well as from normal skin of healthy human controls (control group),and each group had a sample size of 10.Real-time RT-PCR was performed to measure the mRNA expression of protein kinase D1 gene (PRKD1),and Western blot analysis to determine the protein expression of PKD1,pPKD1-tyr463 and pPKD1-ser916.In addition,immunohistochemical study was conducted to determine the expression of PKD1,pPKD1-tyr463 and pPKD1-ser916 in another 50 paraffin-embedded skin samples of SCC,20 samples of BD,20 samples of AK and 10 normal skin samples.Results PRKD1 mRNA expression significantly differed among the control group (0.64 ± 0.09),SCC group (5.37 ± 1.06),BD group (2.69 ± 0.72) and AK group (2.43 ± 0.46) (F =21.37,P ＜ 0.05),and was significantly higher in the SCC,BD and AK groups than that in the control group (P ＜ 0.05),as well as in the SCC group than that in the AK and BD groups (both P ＜ 0.05).However,no significant difference in the PRKD1 mRNA expression was observed between the BD group and AK group (P ＞ 0.05).Immunohistochemical study showed that the total PKD1 protein and pPKD1-tyr463 in the SCC and BD groups were mainly expressed in the cytoplasm and cell membrane of spinous layer cells and atypical cells,and their expression rates were significantly higher than those in the AK group and control group (all P ＜ 0.01).The pPKD1-ser916 was only slightly expressed in some cancer nests of well-differentiated SCC tissues,but not in poorly-differentiated SCC,AK,BD tissues and normal skin tissues.In the SCC group,the expression rate of PKD1 increased with the increase of the pathological grade of SCC,and the PKD1 expression was positively correlated with pPKD1-tyr463 expression (rcc =0.479,P ＜ 0.05).Western blot results were consistent with immunohistochemical findings.Conclusion PKD1 and pPKD1-tyr463 may be involved in the development and differentiation of skin tumors derived from stratified squamous epithelium,and PKD1 may exert promotive effects on the formation of cutaneous SCC by activating the Tyr463 phosphorylation site.

AIM:Toinvestigatetheeffectofnicotinicacidamide(NAA)ontheinfusiondamageofhuman umbilical cord mesenchymal stem cells ( hUC-MSCs) under the condition of instant blood-mediated inflammatory reaction ( IBMIR) .METHODS:Normal peripheral blood without anticoagulant at volume of 2.7 mL was mixed with 0.3 mL phys-iological saline (as blank group), CFSE labeled hUC-MSCs (1 ×106 cells in 0.3 mL as MSC group) and CFSE labeled hUC-MSCs (1 ×106 cells in 0.3 mL) preprocessed with NAA at concentration of 10 mmol/L for 24 h ( as MSC+NAA group) , respectively.The mixture was immediately injected into the improved Chandler Loop model, placed in 37℃water bath, and then started the peristaltic pump at the speed of 20 mL/min for 1 h.The number of CFSE labeled hUC-MSCs, platelets, white blood cells were counted and the concentration of complement C3a was measured before and after cycling, respectively.RESULTS: After 1 h circulation, the platelet dissipation rate were ( 29.96 ±10.88 )% in blank group, (77.76 ±19.29)% in MSC group all and (50.13 ±18.10)% in MSC +NAA group; and the leukocyte counts were (37.82 ±13.81)%in blank group, (64.57 ±17.08)% in MSC group and (41.52 ±17.26)% in MSC+NAA group. Compared with blank group, the differences of the dissipation rates in MSC group and MSC+NAA group all had statistical significance.The hUC-MSCs relative survival rate in MSC+NAA group was higher than that in MSC group.C3a concentra-tions in blank group, MSC group and MSC+NAA group were (206.27 ±58.10), (230.47 ±39.61) and (208.37 ± 40.66) μg/L, respectively.CONCLUSION:Co-circulating the mixture of hUC-MSCs with normal peripheral blood with-out anticoagulant in the improved Chandler Loop for 1 h depletes a large number of hUC-MSCs and blood components, and increases C3a, suggesting that this model can induce IBMIR.NAA has a protective effect on the hUC-MSCs in the infusion damage by inhibiting IBMIR, reducing the wastage of the blood components and enhancing the survival rate of the hUC-MSCs.
