Objective: To investigate the trends in incidence and mortality of lung cancer in Huangpu District, Shanghai Municipality from 2002 to 2019, so as to provide the evidence for formulating lung cancer prevention and control measures. Methods: Data of lung cancer incidence and mortality among residents in Huangpu District from 2002 to 2019 were collected through the Shanghai Cancer Registration and Reporting Management System. The crude incidence and mortality of lung cancer was calculated, and standardized by the data from the Chinese Fifth National Population Census in 2000 (Chinese-standardized rate) and the Segi's world standard population in 1960 (world-standardized rate). The trends in incidence and mortality of lung cancer among residents by age and gender were evaluated using annual percent change (APC). Results: A total of 12 965 cases of lung cancer were reported in Huangpu District from 2002 to 2019, and the crude incidence rate was 80.66/105, the Chinese-standardized incidence rate was 34.54/105, and the world-standardized incidence rate was 31.30/105, all showing upward trends (APC=4.588%, 2.933% and 3.247%, all P<0.05). A total of 10 102 deaths of lung cancer were reported, and the crude mortality rate was 62.30/105, showing an upward trend (APC=0.959%, P<0.05); the Chinese-standardized mortality was 25.93/105, and the world-standardized mortality was 22.05/105, both showing downward trends (APC=-1.282% and -1.263%, both P<0.05). The crude incidence and mortality rates of lung cancer in males were higher than those in females (101.39/105 vs. 60.52/105, 85.45/105 vs. 39.87/105, both P<0.05). The crude incidence and mortality rates of lung cancer showed upward trends with age (both P<0.05), reaching their peaks in the age groups of 80-<85 years (341.37/105) and 85 years or above (355.97/105), respectively. Conclusions The incidence of lung cancer showed an upward trend, while the mortality showed a downward trend in Huangpu District from 2002 to 2019. Elderly men were the high-risk group for lung cancer incidence and mortality.

Sialic acid-binding immunoglobulin-like lectins(Siglecs)are expressed on most white blood cells and play a key role in signal transduction of immune cells.Recent studies have shown that many bacterial pathogens regulate the host immune response through the interaction between sialic acid(Sia)and Siglecs,thereby influencing the occurrence and development of diseases.Understanding bacterial pathogenic mechanisms is essential to identify potential effective therapeutic targets and help manage bacterial infectious diseases.Herein,the structure,biological function,and research progress in Siglecs in bacterial in-fectious diseases are briefly reviewed.

Brucellosis is one of the most significant infectious diseases affecting both humans and animals.It poses a consid-erable risk to human health and the advancement of animal husbandry.Vaccination has emerged as a highly effective strategy for preventing and controlling brucellosis infection.Currently,numerous live attenuated vaccines for animals are available on the market.Despite the lack of a vaccine for human use,research in the fields of genetic engineering and molecular bioinformat-ics has led to the development of a number of subunit vaccines,including DNA vaccines,multi-epitope vaccines,recombinant protein vaccines,and vector vaccines.Vaccine adjuvants have been developed to address the varying requirements of different immune responses.This paper will review the research progress of brucellosis vaccines and introduce the commonly used vac-cine adjuvants,with a view to providing new ideas for the development of subsequent vaccines.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

As interstitial collagen,type Ⅲ collagen(Col Ⅲ)does not express in normal glomeruli.However,in Col Ⅲ nephropathy,a large amount of Col Ⅲ deposit in the mesangial and subendothelial area of the glomeruli.IgA nephropathy with Col Ⅲ deposition was extremely rare.In this article,we reported two cases of such disease.After treating with immunosuppressive agents or traditional Chinese medicine decoction,the renal function of the two patients remained stable and the urinary protein levels reduced significantly.

Objective:Chronic urticaria presents a chronic process of recurrent attacks,and its first-line treatment is second-generation antihistamine with limited treatment options.The efficacy of antihistamine varies among individuals and cannot meet the needs of all patients.This study aims to explore the clinical efficacy and safety of Zhiyang Xiaozhen granules combined with antihistamine in the treatment of chronic urticaria patients. Methods:We retrospectively analyzed the clinical data of patients with chronic urticaria who visited the Xiangya Hospital of Central South University from April 2020 to March 2021.The patients who received conventional second-generation antihistamine treatment were selected as a control group,while the patients who received combined treatment with Zhiyang Xiaozhen granules on the basis of conventional second-generation antihistamine treatment were selected as an observation group.The differences in the Weekly Urticaria Activity Score(UAS7)and Dermatology Life Quality Index(DLQI)between the 2 groups before and 4 weeks after treatment were compared.The Symptom Score Reduce Index(SSRI)was used to evaluate and compare the efficacy of the 2 treatment regimens. Results:After 4 weeks of treatment,the UAS7 levels in both groups were significantly reduced(P=0.001 and P<0.001,respectively).The effective rates of the control group and the observation group were 61.11%and 59.38%,respectively when converting UAS7 to SSRI for efficacy evaluation,and there was no statistically significant difference in efficacy between the 2 groups(P>0.05);however,when converting DLQI to SSRI for efficacy evaluation,the effective rates of the control group and the observation group were 33.33%and 46.88%,respectively,and the difference in efficacy between the 2 groups was statistically significant(P<0.001).There were 3 patients with adverse drug reactions related to drowsiness in both groups. Conclusion:The combination of Zhiyang Xiaozhen granules and second-generation antihistamine can effectively improve disease activity in patients with chronic urticaria,and the improvement in quality of life is better than that with the second-generation antihistamine alone.

Objective: To report the clinical manifestations and laboratory features of five patients with congenital thrombotic thrombocytopenic purpura (cTTP) and explore its standardized clinical diagnosis and treatment along with a review of literature. Methods: Clinical data of patients, such as age of onset, disease manifestation, personal history, family history, and misdiagnosed disease, were collected. Treatment outcomes, therapeutic effects of plasma infusion, and organ function evaluation were observed. The relationship among the clinical manifestations, treatment outcomes, and ADAMTS13 gene mutation of patients with cTTP was analyzed. Additionally, detection of ADAMTS13 activity and analysis of ADAMTS13 gene mutation were explored. Results: The age of onset of cTTP was either in childhood or adulthood except in one case, which was at the age of 1. The primary manifestations were obvious thrombocytopenia, anemia, and different degrees of nervous system involvement. Most of the patients were initially suspected of having immune thrombocytopenia. Acute cTTP was induced by pregnancy and infection in two and one case, respectively. ADAMTS13 gene mutation was detected in all cases, and there was an inherent relationship between the mutation site, clinical manifestations, and degree of organ injury. Therapeutic or prophylactic plasma transfusion was effective for treating cTTP. Conclusions: The clinical manifestations of cTTP vary among individuals, resulting in frequent misdiagnosis that delays treatment. ADAMTS13 activity detection in plasma and ADAMTS13 gene mutation analysis are important bases to diagnose cTTP. Prophylactic plasma transfusion is vital to prevent the onset of the disease.

Aim To explore the protective effect of Yishen Huashi Granule (YSHS) on streptozotocin (STZ) - indueed diabetes nephropathy (DN) in mice and its possible mechanism. Methods The STZ induced DN mice model was established, which was randomly divided into model group, YSHS group and YAP inhibitor Vertepofin group, and the eontrol group was also established. The intervention was started eight weeks after the successful modeling with the course of four weeks. Urine protein concentration before and after intervention in each group as well as serum creatinine (Scr) and blood urea nitrogen (Bun) levels after intervention were measured. After the treatment, the mice were sacrificed, and the pathological changes of glomeruli were observed by light microscope HE staining. The protein expression of YAP, p-YAP S127 and CTGF were detected by Western blot, and the mRNA expressions of YAP, CTGF and podocyte functional proteins nephrin, podophyxin and WT1 were detected by RT-PCR. Results The biochemical indexes of YSHS group were better than those of model group, and HE staining showed that the pathological injury of glomeruli was improved. In the model group the protein expression of YAP, p-YAP (S127) and CTGF as well as the mRNA expression of YAP and CTGF increased, while the mRNA expression of nephrin, podocalyxin and WT1 decreased. After YSHS treatment, the protein expression of YAP, p-YAP S127, CTGF and the mRNA expression of YAP and CTGF decreased, while the mRNA expression of nephrin, podocalyxin and WT1 increased. Conclusions YSHS can reduce urinary protein, protect renal function and alleviate glomerular pathological injury in DN mice. Its possible mechanism may be related to the down-regulation of YAP in renal tissue, the reduction of CTGF expression level and the up-regulation of podocyte protein mRNA expression.

AIM:To evaluate the changes in corneal biomechanics of patients with moderate refractive error after receiving small-incision lenticule extraction(SMILE)and femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)using the corneal visualization Scheimpflug technology(Corvis ST).METHODS:Prospective cohort study. A total of 65 moderate myopia patients(65 eyes)who were scheduled to undergo refractive surgery at the Ophthalmic Refractive Surgery Center of the Ningxia Eye Hospital from November 2020 to November 2021 were included in the study, and there were 30 eyes in the SMILE group and 35 eyes in the FS-LASIK group. The changes in corneal biomechanical parameters, including integrated radius(IR), inverse concave radius(ICR), deformation amplitude ratio 2mm(DAR2), stiffness parameter at first applanation(SP-A1), ambrosio relational thickness(ARTh)and the central curvature radius at highest concavity(HC-Radius)were observed by Corvis ST between both groups preoperatively and 1 and 3mo postoperatively.RESULTS: There were no statistical significance in biomechanical parameters between two groups of patients 1 and 3mo postoperatively(P>0.05). IR, ICR and DAR2 of each groups of patients 1 and 3mo postoperatively were significantly increased than those preoperatively, and SP-A1, ARTh and HC-Radius were significantly decreased than those preoperatively(all P<0.05). The biomechanical parameters at 1mo and 3mo postoperatively showed no statistical significance(P>0.05). In addition, a positive correlation was found between central corneal thickness(CCT)and ARTh and SP-A1 of the two groups of patients at 3mo postoperatively(FS-LASIK group: r=0.727, 0.819, SMLIE group: r=0.683, 0.434, all P<0.05), while a negative correlation was found between CCT and IR and ICR at 3mo postoperatively.(FS-LASIK group: r=-0.697, -0.622, SMLIE group: r=-0.447, -0.491, all P<0.05).CONCLUSION:For patients with moderate myopia, both SMILE and FS-LASIK can reduce corneal biomechanical stability. Both surgeries showed no significant differences in the effect on biomechanical, and the biomechanical has been stabilized at 1mo postoperatively. A correlation was found between postoperative CCT and ARTh, SP-A1, IR and ICR.

ObjectiveTo observe the effects of Scutellariae Radix （SR）-Paeoniae Radix Rubra （PRR） combination of different proportions on the expression of the Toll-like receptor 4 （TLR4）/myeloid differentiation factor 88 （MyD88）/nuclear transcription factor κB （NF-κB） and phosphatidylinositol kinase （PI3K）/protein kinase B （Akt）/mammalian target of rapamycin （mTOR） signaling pathways in liver tissues of rats with hepatic fibrosis and explore the mechanism against hepatic fibrosis. MethodSixty male SD rats of SPF grade were randomly divided into a normal group， a model group， a positive control （silymarin） group， and SR-PRR 1∶1， SR-PRR 1∶2， and SR-PRR 1∶4 groups， with 10 rats in each group. The hepatic fibrosis model was induced in rats except for those in the normal group by intraperitoneal injection of 40% tetrachloromethane （CCl₄）-olive oil solution at 3 mL·kg^-1， 5 mL·kg^-1 for the first time， for 8 weeks， twice per week. After 4 weeks， rats were treated correspondingly at 10 mL·kg^-1 by intragastric administration， and the body weight of rats in each group was weighed for 8 weeks. After administration， histopathological changes in the liver were observed. Serum alanine aminotransferase （ALT）， aspartate aminotransferase （AST）， hyaluronic acid （HA）， laminin （LN）， albumin （ALB）， alkaline phosphatase （AKP）， and superoxide dismutase （SOD） activities， malondialdehyde （MDA）， and hydroxyproline （HYP） content in liver tissues were detected. The mRNA expression levels of TLR4， MyD88， NF-κB， PI3K， Akt， and mTOR in the liver of rats were detected by real-time fluorescence-based quantitative polymerase chain reaction （Real-time PCR）. ResultCompared with the model group， SR-PRR combination of different proportions could recover the body weight and improve the pathological injury of the liver. As revealed by enzyme linked immunosorbent assay （ELISA） results， compared with the normal group， the model group showed increased ALT， AST， HA， LN， AKP， MDA， and HYP levels to different degrees （P<0.05）. Compared with the model group， the groups with drug intervention showed decreased levels of ALT， AST， HA， LN， AKP， MDA， and HYP， potentiated SOD activity， and increased level of ALB （P<0.05）. As revealed by Real-time PCR results， compared with the normal group， the model group showed increased mRNA expression of TLR4， MyD88， NF-κB， PI3K， Akt， and mTOR （P<0.05）. Compared with the model group， the groups with drug intervention showed reduced mRNA expression of TLR4， MyD88， NF-κB， PI3K， Akt， and mTOR in the liver of rats （P<0.05）. ConclusionSR-PRR combination of different proportions can improve the histopathological injury in liver tissues caused by CCl₄， with the optimal effect observed in the SR-PRR 1∶4 group. SR-PRR may inhibit the development of liver fibrosis by inhibiting the expression of TLR4/MyD88/NF-κB and PI3K/Akt/mTOR signaling pathways， thereby alleviating chemical-induced liver injury.
