Objective: To retrospectively analyze the clinical data of 474 newborns with hyperbilirubinemia, and to investigate the clinical characteristics of hyperbilirubinemia caused by ABO hemolytic disease of the fetus and newborn (ABO-HDFN) and factors influencing the phototherapy duration. Methods: A total of 474 neonates with hyperbilirubinemia treated in the First Hospital of Lanzhou University from January 2019 to January 2023 were enrolled. Blood type identification and the standard serological tests (direct antiglobulin test, serum free antibody test, and antibody elution test) were performed for all neonates. Baseline clinical data were collected and analyzed. According to the results of the hemolysis tests, neonates were divided into hemolytic jaundice group and non-hemolytic jaundice group. Clinical indicators, including hemoglobin levels, length of hospital stay, and phototherapy duration, were compared between the two groups. A multiple linear regression model was used to explore clinical factors influencing the duration of phototherapy. Results: Among the 474 neonates with hyperbilirubinemia, 354 were diagnosed with ABO-HDFN (hemolytic group), while 120 were without ABO-HDFN (non-hemolytic group). The incidence of ABO-HDFN in neonates with blood type A (55.93%, 198/354) was significantly higher than those with blood type B (44.07%, 156/354) (P<0.05). Furthermore, neonates born to multiparous women had a significantly higher ABO-HDFN incidence (81.56%, 146/179) than first-born neonates (70.51%, 208/295) (P<0.05). Neonates in the hemolytic group had significantly lower hemoglobin levels (170.67±21.86 g/L vs 178.99±22.05 g/L, P<0.001), lower red blood cell counts (4.66±0.63×10 /L vs 4.89±0.59×10 /L, P<0.05), and lower hematocrit (50.05±6.56% vs 52.61±6.75%, P<0.05) compared to the non-hemolytic group. Additionally, the hemolytic group had significantly longer hospital stays (6 [5, 9] days vs 6 [4, 8] days), longer phototherapy duration (62 [38, 84.25] h vs 53 [34.25, 64.77] h), and higher frequency of jaundice episodes (9 [7, 13] times vs 8 [6, 12] times] compared to the non-hemolytic group (all P<0.05). Regression analysis indicated that a positive indirect Coombs test and multiparity were independent risk factors associated with prolonged phototherapy duration (P<0.05). Conclusion: ABO incompatibility is the leading cause of hemolytic disease in neonates, particularly in cases where the mother has blood type O and the neonate has blood type A. In such cases, close monitoring of bilirubin levels is strongly recommended. Multiparous pregnancies increase the risk of alloimmune hemolysis. Therefore, neonates born to multiparous women may require more frequent bilirubin monitoring and appropriate prenatal interventions when necessary. Additionally, changes in indicators such as hemoglobin level and red blood cell count should be closely monitored as early warning indicators for hemolytic anemia and bilirubin elevation.

Objective:This study aimed to explore the status of radiological Kashin-Beck disease (KBD) among school-aged children in Chamdo City, Tibet, through a 3-year monitoring survey, providing epidemiological evidence for prevention and control strategies.Methods:The target areas for this study were Luolong, Bianba, and Basu counties in Chamdo City, Tibet Autonomous Region, identified as having the most severe historical cases of KBD. Children aged 7-12 years attending school were enrolled as study subjects. Anteroposterior X-ray films of the right-hand were taken, and radiological diagnoses were made based on the "Diagnosis of Kashin-Beck Disease" criteria (WS/T 207-2010). Two experienced researchers independently reviewed the X-rays, and intra- and inter-group consistency were assessed using weighted Kappa values and percentage agreement. Cross-sectional surveys were conducted in 2017 and 2020 to describe the X-ray detection rates of KBD, and logistic regression analysis was employed to construct a predictive model of risk factors for radiological KBD cases.Results:In 2017, a total of 5,711 children aged 7-12 years in Chamdo City, Tibet, participated in the baseline cross-sectional survey (average age 9.2 years, 48.0% female), with 28 cases of radiological KBD. The age- and gender-standardized prevalence rate was 0.527%. In 2020, 6,771 participants (average age 9.3 years, 49.5% female) underwent a second cross-sectional survey, with 9 cases of radiological KBD and a standardized prevalence rate of 0.134%. Logistic regression analysis indicated that older age [ OR=2.439, 95% CI(1.299, 4.580), P=0.006] and female gender [ OR=8.157, 95% CI(1.016, 65.528), P=0.048] were independent risk factors for radiological KBD cases. Conversely, higher residential altitude, under the premise of Tibet's high altitude, was a protective factor [ OR=0.995, 95% CI(0.990, 0.999), P=0.032). Conclusion:The radiographically positive detection rate of KBD among school-aged children in Chamdo City, Tibet Autonomous Region, is at an extremely low level and showing a declining trend, reaching the historical standard in 2020. Considering the absence of positive signs in affected children, it suggests that local KBD has been effectively eliminated.

OBJECTIVE:At present,there are many reports on the related factors associated with the incidence of cervical spine instability in patients with rheumatoid arthritis,but there are problems such as small sample size and many confounding factors,and the research results of various studies on the same related factors are also different.This article analyzed the factors related to cervical spine instability in patients with rheumatoid arthritis by means of a systematic review. METHODS:Articles related to cervical spine instability in patients with rheumatoid arthritis were collected by searching both Chinese and English databases until March 2023.The outcome of cervical spine instability in patients with rheumatoid arthritis was used as the grouping criterion to abstract basic information,baseline patient characteristics,laboratory-related tests,medication use,and other relevant risk factors.Meta-analysis was done using Stata 14.0 software. RESULTS:(1)Sixteen relevant studies,all of moderate or above quality,were included,including seven studies with case-control studies and nine with cross-sectional studies.The overall incidence of cervical spine instability in patients with rheumatoid arthritis was 43.08%.(2)Meta-analysis showed:Related risk factors included female(OR=0.60,95%CI:0.44-0.82,P=0.002);age at disease onset(SMD=-0.52,95%CI:-0.86 to-0.18,P=0.003);duration of disease(SMD=0.58,95%CI:0.14-1.02,P=0.01);body mass index(OR=0.74,95%CI:0.63-0.88,P=0.001);rheumatoid factors positive univariate analysis subgroup(OR=1.33,95%CI:1.02 to 1.72,P=0.04),C-reactive protein(SMD=0.26,95%CI:0.16-0.35,P=0.00),erythrocyte sedimentation rate(SMD=0.15,95%CI:0.002-0.29,P=0.047),anti-cyclic-citrullinated peptide antibodies(OR=1.73,95%CI:1.19-2.51,P=0.004),28-joint Disease Activity Score(SMD=0.20,95%CI:0.04-0.37,P=0.02),destruction of peripheral joints(OR=2.48,95%CI:1.60-3.85,P=0.00),and corticosteroids(OR=1.91,95%CI:1.54-2.37,P=0.00)were strongly associated with the development of rheumatoid arthritis-cervical spine instability.Female and corticosteroid use were independently associated with the occurrence of rheumatoid arthritis-cervical spine instability. CONCLUSION:Based on clinical evidence from 16 observational studies,the overall incidence of rheumatoid arthritis-cervical spine instability was 43.08%.However,the incidence of cervical spine instability in rheumatoid arthritis patients varied greatly among different studies.Gender(female)and the use of corticosteroids were confirmed as independent correlation factors for the onset of cervical spine instability in patients with rheumatoid arthritis.The results of this study still provide some guidance for early clinical recognition,diagnosis,and prevention of rheumatoid arthritis-cervical spine instability.

Objective:To investigate syphilis infection and related factors among HIV-infected patients being followed up for more than one year in Zhejiang Province.Methods:Data were collected from the China Disease Control and Prevention Information System, and information such as demographic characteristics, viral load levels, and syphilis serologic test results was collected from HIV-infected persons who were diagnosed with HIV more than 1 year, aged ≥15 years with a current address in Zhejiang Province through December 31, 2022. The logistic regression model analyzed the prevalence of syphilis and the related factors. The SPSS 19.0 software was used for statistical analysis.Results:A total of 33 734 HIV-infected patients, with the prevalence of syphilis was 5.6% (1 879/33 734). Among the syphilis cases, the prevalence of syphilis was 6.4% (1 774/27 934) of males, 7.5% (640/8 543) of 25-34 years old age group, 7.6% (1 025/13 423) of unmarried, 8.3% (1 239/14 862) of homosexual transmission, 6.9% (214/3 080) with a non-local registered residence and 9.6% (602/6 267) with a history of STD before the HIV diagnosis. Multivariate Logistic regression analysis showed that participants who were male (a OR=2.19, 95% CI:1.77-2.72), 25-34 years old age group (a OR=1.80, 95% CI:1.47-2.20), homosexual transmission (a OR=1.67, 95% CI:1.49-1.88), with other provinces registered residence (a OR=1.26, 95% CI:1.09-1.47), and with a history of sexually transmitted disease (STD) before the HIV diagnosis (a OR=1.98, 95% CI:1.78-2.20) were associated with increased risk of syphilis. Being married (a OR=0.79, 95% CI:0.68-0.92) was associated with a decreased risk of syphilis. Conclusions:Syphilis infections were high in HIV-infected patients followed up more than one year in Zhejiang Province. It is recommended that syphilis surveillance and screening frequency should be strengthened among HIV-infected persons with characteristics such as male, homosexual transmission, and STD history.

Objective To investigate the clinical safety of Chinese medicine combined with immune checkpoint inhibitors(ICIs)for the treatment of non-small cell lung cancer(NSCLC)at stage Ⅲ-Ⅳ,and to explore the influencing factors of immune-related adverse events(irAEs)in the treatment of stage Ⅲ-Ⅳ NSCLC with ICIs.Methods A retrospective analysis was carried out for the investigation of the distribution of traditional Chinese medicine(TCM)syndromes,related medication information and the occurrence of irAEs in the hospitalized patients diagnosed as stage Ⅲ-Ⅳ NSCLC and treated with Chinese medicine combined with ICIs in the Oncology Department of Guangdong Provincial Hospital of Chinese Medicine(University-town Branch)from September 1,2019 to August 31,2022.And the levels of adverse reactions and their possible influencing factors were analyzed.Results(1)The treatment for the 90 NSCLC patients involved 4 regimens,namely ICIs monotherapy,ICIs combined with chemotherapy,ICIs combined with anti-angiogenic drugs,and ICIs combined with chemotherapy and anti-angiogenic drugs.Among them,ICIs combined with chemotherapy and anti-angiogenic drugs were used most frequently for 52 cases(49.1%).A total of 8 kinds of ICIs drugs were used,of which Tislelizumab accounted for the highest proportion(43 cases,40.6%).(2)All of the patients were classified into 5 syndrome types,namely qi deficiency and phlegm-stasis syndrome,phlegm-stasis obstructing the collateral syndrome,qi and yin deficiency syndrome,qi and blood deficiency syndrome,and phlegm-heat accumulation syndrome.Among them,qi deficiency and phlegm-stasis syndrome was the most common type(80 cases,88.9%).(3)The overall incidence of irAEs was 38.9%(35/90),and irAEs being or above grade 3(G3)level in the patients only accounted for 5.6%(5/90).The initial irAEs usually occurred at the immunotherapy course 1-3(17 cases,48.6%).The incidence of irAEs being or above G3 level in the patients treated with ICIs monotherapy was higher than that in the patients treated with the combined therapy(33.3%vs 3.6%).(4)The Eastern Cooperative Oncology Group(ECOG)performance status(PS)score of 0-1(OR=8.218,95%CI:1.607-42.023,P = 0.011)and adrenal metastasis(OR=4.497,95%CI:1.237-16.354,P=0.022)were the independent risk factors for irAEs in patients with stageⅢ-Ⅳ NSCLC treated by ICIs(P＜0.05).Conclusion Chinese medicine has the potential to reduce the incidnence of adverse reactions of ICIs in the treatment of stage Ⅲ-Ⅳ NSCLC.PS score of 0-1 and adrenal metastasis may be the independent risk factors for irAEs in patients with stage Ⅲ-Ⅳ NSCLC treated by ICIs.

Aim To investigate the effects of Radix Angelica Sinensis and Radix Hedysari ultrafiltration(RAS-RH)on oxidative stress and inflammatory injury of human umbilical vein endothelial cells(HUVECs)induced by ionizing radiation.Methods The model of HUVECs damage induced by 6 Gy X-rays was estab-lished.HUVECs were treated with different concentra-tions of RAS-RH(100,200,400 μg·L-1).The proliferative activity of HUVECs was detected by CCK-8 method,the structural changes of mitochondria were observed by transmission electron microscope,the level of ROS was detected by DCFH-DA probe,the change of intracellular mitochondrial membrane potential was detected by JC-1 kit,and the apoptosis and cycle were detected by flow cytometry.The contents of IL-6 and TNF-α in cells were detected by ELISA.The activities of MDA,CAT,SOD and GSH-PX were detected by biochemical kit.The gene expression levels of Nrf2,HO-1,NF-κB,eNOS and IL-6 were detected by qRT-PCR,and the expression levels of Nrf2,HO-1,eNOS,NF-κB,p-NF-κB and IL-6 protein were detected by Western blot.Results Compared with the model group,RAS-RH could increase the activity of HUVECs induced by ionizing radiation,decrease the rate of ap-optosis,decrease the level of intracellular ROS,re-duce the injury of intracellular mitochondria,increase the level of mitochondrial membrane potential,promote the expression of Nrf2,HO-1 and eNOS,and inhibit the expression of NF-κB and IL-6.Conclusions RAS-RH has anti-radiation,antioxidant and anti-in-flammatory effects,which may reduce the oxidative stress and inflammatory damage of HUVECs induced by ionizing radiation by activating the activity of Nrf2/HO-1 signal pathway,thus promoting the activity of cell proliferation.

AIM:To evaluate the efficacy,safety,and economy of camrelizumab(CAM)combined with platinum-containing chemotherapy(CT)for the first-line treatment of locally advanced/meta-static non-small cell lung cancer(NSCLC).METH-ODS:Chinese and English databases such as Pubmed,the Cochrane Library,China Knowledge Network,Wanfang Data,and other related web-sites were systematically searched.After literature screening,quality assessment,and data extraction of the literature according to the inclusion and ex-clusion criteria,two researchers conducted a rapid health technology assessment(HTA).RESULTS:A total of 7 systematic evaluations/Meta-analyses and 17 economics evaluations were included.In terms of effectiveness,compared to docetaxel che-motherapy,CAM+CT significantly prolonged the overall survival(OS),progression-free survival(PFS),and improved the objective remission rate(ORR)of mutation-negative patients with locally ad-vanced/metastatic NSCLC.Compared with CT and pembrolizumab(PEM),CAM+CT significantly pro-longed the PFS,and improved the ORR of mutation-negative patients with locally advanced/metastatic NSCLC.Subgroup analysis showed that CAM+CT significantly prolonged PFS in patients with PD-L1 ≥1％and PD-L1 ≥ 50％compared with CT.Compared with CT,CAM+CT significantly prolonged the OS and PFS of mutation-negative patients with locally advanced/metastatic squamous NSCLC.Compared with sintilimab(SIN),CAM+CT significantly pro-longed the PFS of mutation-negative patients with locally advanced/metastatic squamous NSCLC.Sub-group analysis showed that CAM+CT significantly prolonged OS in patients with PD-L1＜1％com-pared with CT.In terms of safety,CAM+CT was comparable in terms of the occurrence of all grades of adverse events,but the incidence of grade 3 or higher treatment-related adverse events was significantly increased compared with CT and PEM for mutation-negative locally advanced/meta-static NSCLC patients.CAM+CT was significantly in-creased the occurrence of all grades of adverse events compared with CT,but was comparable in terms of the occurrence of grade 3 or higher treat-ment-related adverse events.In terms of economy,CAM+CT has a cost-effectiveness advantage over CT for patients with mutation-negative advanced/metastatic squamous NSCLC.CAM+CT has a cost-effectiveness advantage over CT and PEM+CT;and CAM+CT does not have a cost-effectiveness ad-vantage over SIN+CT for patients with mutation-negative locally advanced/metastatic non-squa-mous NSCLC.CONCLUSION:CAM+CT has good ef-ficacy and cost-effectiveness for the first-line treat-ment of locally advanced/metastatic NSCLC,and the safety aspect is compared with CT,PEM or slightly worse.

Objective To assess the association between Metformin use and the risk of dementia in patients with type 2 diabetes mellitus(T2DM).Methods The research data came from the big medical data platform of Yinzhou District,and we constructed a cohort of T2DM patients who had initiated treatment of Metformin or sulfonylurea since January 1,2009.The inverse probability of treatment weighting(IPTW)was used to control the baseline confounding factors,and the Cox regression model was used to estimate the HR(95%CI)of the association between Metformin use and dementia risk.Results The incidence rate of dementia in new users of Metformin(41181 persons)and sulfonylureas(38092 persons)was 128.4 per 100000 person years and 142.3 per 100000 person years respectively.Compared with sulfonylureas,the crude analysis with no adjustment for confounding factors showed that there was a negative association between the use of Metformin and the incidence of dementia,with an HR(95%CI)0.930(0.800～1.090).After adjusting for potential confounders with IPTW,Metformin was not significantly associated with the risk of dementia HR(95%CI)1.040(0.890～1.220).The subgroup analysis results for different baseline characteristics were consistent with the primary analysis results,and there were no statistically significant associations between Metformin and dementia incidence risk in all subgroups.Conclusions There is no significant association between the use of Metformin and the risk of dementia in T2DM patients in the Yinzhou District.
