Trends in Mortality Related to Hepatitis B and C from 1990 to 2019in the Western Pacific Region

Background/Aims@#This study aimed to analyze the trends in mortality attributed to hepatitis B and C around the Western Pacific region from 1990 to 2019. @*Methods@#We used data from the Global Burden of Disease Study for a systematic analysis. The deaths related to hepatitis B and C were analyzed by age, sex, year, risk factors, geographical location, and Socio-demographic Index (SDI). @*Results@#From 1990 to 2019, the annual total deaths from hepatitis B decreased from 0.266 to 0.210 million and those from hepatitis C increased from 0.119 to 0.142 million in the Western Pacific region. The age-standardized mortality rate (ASMR) of hepatitis B and C decreased by 63.5% and 48.0%, respectively. The declines in the ASMR related to hepatitis B and C were only detected in 12 and two Western Pacific countries, respectively. As the major risk factors, the contribution of alcohol use to hepatitis B deaths was 52% and drug use to hepatitis C was 80%. In males and females, the ASMR attributed to hepatitis B decreased by 61% and 71%, respectively, and the ASMR attributed to hepatitis C decreased by 43% and 55%, respectively. The association between SDI and ASMRs suggested that hepatitis B and C, respectively, showed an overall decline and stable trends as the SDI improved in the Western Pacific region. @*Conclusions@#Although the mortality rate from hepatitis B and C decreased from 1990 to 2019, notable variation was observed among 27 Western Pacific countries. Efforts targeting hepatitis B and C prevention and treatment are still required in this region, especially for the pandemic countries.

Construction and evaluation of risk prediction model for renal injury in tumor patients receiving PD-1 inhibitor treatment / 解放军医学杂志

Objective To explore the risk factors for renal injury in tumors patients treated with programmed death receptor-1(PD-1)inhibitor,and further construct a column chart model to predict the likelihood of renal injury in patients.Methods The present study is a single center retrospective analysis.447 patients with tumors treated with PD-1 inhibitors in the Third Affiliated Hospital of Soochow University between January 2018 and January 2021 were included and followed up until January 2022.Kidney injury was defined as acute kidney disease(AKD).All patients were divided into AKD group(n=71)and non-AKD group(n=376 according to whether PD-1 inhibitor associated with AKD development at the end of follow-up.Basic information,disease and medication situation,laboratory indicators,and the incidence of extrarenal immune related adverse events(irAEs)during follow-up period were compared between the two groups.Univariate and multivariate logistic regression models were used to identify independent risk factors for PD-1 inhibitor associated AKD.The present study randomly divided all samples(n=447)into training set(n=313)and validation set(n=134)in a 7:3 ratio,built nomogram prediction models in the training set according to the screened independent risk factors,drawn the receiver operating characteristic(ROC)curves to evaluate the discrimination of the models,drawn calibration curves to evaluate the calibration of the models,and drawn clinical decision curve analysis(DCA)to explore the clinical validity and benefit rate of the models.Results The combination of antibiotics,diabetes,hypertension,extrarenal irAEs and cystatin C(Cys C)in AKD group were significantly higher than those in non-AKD group(P<0.05),but hemoglobin(Hb)was significantly lower than that in non-AKD group(P<0.05).Single factor logistic regression analysis showed that combination of antibiotics,diabetes,hypertension,extrarenal irAEs,lower Hb,estimated glomerular filtration rate(eGFR),higher blood urea nitrogen(BUN),serum creatinine(SCr),Cys C,fasting blood glucose(FBG),and alanine transaminase(ALT)were risk factors for PD-1 inhibitor related AKD(P<0.05).Multivariate logistic regression analysis showed that concomitant extrarenal irAEs,lower Hb,higher SCr,and direct bilirubin(DBIL)were independent risk factors for PD-1 inhibitor associated AKD(P<0.05).Based on the independent risk factors mentioned above,a column chart prediction model was further established and validated.The results showed that the area under the ROC curve(AUC)of the training and validation sets of the model were 0.703(95%CI 0.628-0.777)and 0.791(95%CI 0.671-0.911),respectively,indicating good discrimination.The calibration curves of both the training and validation sets hover around the ideal line of 45°,indicating that the model has good calibration.DCA shows that the constructed model curve is far away from the two polar lines(the curve with a net benefit of 0 and the curve with all samples being positive),indicating that the model has good clinical benefits.Conclusion The combination of extrarenal irAEs,lower Hb,higher SCr,and higher DBIL are independent risk factors for the occurrence of PD-1 inhibitor related AKD;The established column chart model has good discrimination and calibration,which can provide guidance for clinical practice.

Effect of Adding GnRH-a in Luteal Support of Fresh Embryo Transfer Cycles with GnRH Antagonist Protocol on Clinical Outcomes / 实用妇产科杂志

Objective:To compare the effect of luteal-phase support administration of gonadotrophin-releasing hormone agonist(GnRH-a)on the outcomes of fresh embryo transfer in GnRH antagonist cycles,and explore a more appropriate protocol of luteal-phase support.Methods:A retrospective analysis was performed on the infer-tility patients who receiving in vitro fertilization or intracytoplasmic sperm injection embryo transfer(IVF/ICSI-ET)in the Reproductive Medicine Center of our hospital from January 2018 to December 2021.Our study collected clini-cal data from 674 cycles of infertility patients undergoing fresh cycle transplantation using antagonist regimens.The patients were divided into the control group(n =348)and the observation group(n =326)according to if Gn-RH-a was added to the luteal phase.The patients in control group were given standard luteal support treatment,while the patients in observation group were given multiple-dose GnRH-a 0.1mg to standard luteal support treat-ment after egg retrieval.The general data,ovulation induction and clinical outcome were compared between the two groups.Results:Between the two groups of patients,there was no statistically significant difference in age,years of infertility,body mass index(BMI),basal follicle stimulating hormone(bFSH),days and total amount of gonadotropin(Gn),chorionic gonadotropin(HCG),luteinizing hormone(LH),estradiol(E2)and progesterone(P),the number of retrieved oocytes,MII oocytes,number of embryos,normal fertilization rate,moderate to se-vere ovarian hyperstimulation syndrome(OHSS)rate,abortion rate,live birth rate,multiple pregnancy rate,inci-dence of pregnancy complications,birth weight of offspring,preterm birth rate,and birth defect rate(P>0.05).The implantation rate and clinical pregnancy rate were significantly higher in the observation group compared with control group(P<0.05).Multivariate Logistic regression analysis indicated that age and number of transferred embryos could influence the clinical pregnancy rate(OR 0.958,95%CI 0.917-1.000;OR 1.857,95%CI 1.173-2.942).Conclusions:In fresh embryo transfer cycles with GnRH antagonist protocol,on the basis of conventional luteal support,multi-dose intermittent short-acting GnRH-a for luteal support can achieve a good clin-ical outcome,and may be a suitable luteal support scheme for GnRH antagonist protocol in fresh embryo transfer cycles.

Improvement in the establishment method for the type Ⅱ cardio-renal syndrome rat model / 中国实验动物学报

Objective To establish an improved type Ⅱ cardio-renal syndrome rat model and evaluate it.Methods Twenty male SD rats were randomly divided into sham and model groups with 7 rats in the sham group and 13 rats in the model group.The model group received the method of squeezing the heart under a small animal anesthesia machine to permanently ligate the left anterior descending branch of the coronary artery to cause myocardial infarction.One week later,unilateral nephrectomy(right nephrectomy)was performed.The rats underwent cardiac echocardiography,pathological staining,and blood and urine tests at 6 weeks to verify model establishment.Results Compared with the sham group,the cardiac function assessed by echocardiography and the endogenous creatinine clearance rate in the model group rats were significantly decreased(P<0.01),and the levels of brain natriuretic peptide,blood creatinine,urea nitrogen,and 24 h urine protein in the model group were significantly increased(P<0.01).HE staining revealed a disordered myocardial arrangement,glomerular atrophy,and inflammatory cell infiltration in model group rats.Picric acid-Sirius red staining showed a significant increase in myocardial collagen fibers,an irregular arrangement of renal tubules,and a large amount of collagen deposition in model group rats.The positive staining area ratio was also significantly increased(P<0.01).Conclusions This improved modeling method provided a typeⅡcardio-renal syndrome rat model with s simple operation,minimal surgical trauma,and low mortality rate.This model simulates the early onset of cardiac and renal function damage and pathological changes in type Ⅱ CRS,laying the foundation for systematic and in-depth research on the pathogenesis and pathological mechanism of type Ⅱ cardio-renal syndrome.

Gut microbiota controls the development of chronic pancreatitis: A critical role of short-chain fatty acids-producing Gram-positive bacteria

Chronic pancreatitis (CP) is a progressive and irreversible fibroinflammatory disorder, accompanied by pancreatic exocrine insufficiency and dysregulated gut microbiota. Recently, accumulating evidence has supported a correlation between gut dysbiosis and CP development. However, whether gut microbiota dysbiosis contributes to CP pathogenesis remains unclear. Herein, an experimental CP was induced by repeated high-dose caerulein injections. The broad-spectrum antibiotics (ABX) and ABX targeting Gram-positive (G+) or Gram-negative bacteria (G-) were applied to explore the specific roles of these bacteria. Gut dysbiosis was observed in both mice and in CP patients, which was accompanied by a sharply reduced abundance for short-chain fatty acids (SCFAs)-producers, especially G+ bacteria. Broad-spectrum ABX exacerbated the severity of CP, as evidenced by aggravated pancreatic fibrosis and gut dysbiosis, especially the depletion of SCFAs-producing G+ bacteria. Additionally, depletion of SCFAs-producing G+ bacteria rather than G- bacteria intensified CP progression independent of TLR4, which was attenuated by supplementation with exogenous SCFAs. Finally, SCFAs modulated pancreatic fibrosis through inhibition of macrophage infiltration and M2 phenotype switching. The study supports a critical role for SCFAs-producing G+ bacteria in CP. Therefore, modulation of dietary-derived SCFAs or G+ SCFAs-producing bacteria may be considered a novel interventive approach for the management of CP.

Renal thrombotic microangiopathy induced by targeted therapy combined with immunotherapy: a case report / 中华肾脏病杂志

Targeted therapy and immunotherapy have achieved great success in treating various solid and non-solid tumors, but the incidence of drugs-related adverse events is relatively high. The paper reports a case of renal thrombotic microangiopathy in an intrahepatic cholangiocarcinoma patient who underwent targeted therapy combined with immunotherapy. During the treatment, the tumor burden relieved continuously, but the patient developed proteinuria, edema and hypertension. The ADAMTS13 activity and inhibitors were normal, while the antiphospholipid antibody was positive. The patient was finally diagnosed as glomerular thrombotic microangiopathy with immune complex deposition by renal biopsy. After the cease of the antineoplastic agents and treatment with "cordyceps preparations" and "α-keto acids", the patient's blood pressure dropped to normal, her urine protein turnned to weakly positive, and her renal function remained stable.

Changes in retinal peripheral refractive status and aberrations before and after femtosecond laser-assisted laser in situ keratomileusis and small incision lenticule extraction / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe and compare the changes in retinal peripheral refraction and aberrations after femtosecond laser-assisted laser in situ keratomileusis(FS-LASIK)versus small incision lenticule extraction(SMILE)for myopia correction.METHODS: A total of 71 patients(71 eyes)with myopia who underwent FS-LASIK from October 2022 to April 2023 in our hospital were selected as the FS-LASIK group, and 80 patients(80 eyes)with myopia who underwent SMILE were selected as the SMILE group. All patients underwent corneal wavefront aberration measurement and multispectral refractive topography preoperatively and 3mo postoperatively, as well as refraction difference value(RDV)in the range of 0°～10°, 10°～20°, 20°～30°, 30°～40°, and 40°～53° in the annulus of the retina, which were recorded as RDV-(0°～10°), RDV-(10°～20°), RDV-(20°～30°), RDV-(30°～40°), and RDV-(40°～53°). The results of two groups of patients were compared.RESULTS: No significant differences were observed in RDV-(0°～10°), RDV-(10°～20°), RDV-(20°～30°), RDV-(30°～40°), RDV-(40°～53°)between the two groups at 3mo post-operation(all P&#x003E;0.05). Furthermore, the RDV-(20°～30°), RDV-(30°～40°)and RDV-(40°～53°)of the two groups at 3mo postoperatively were all significantly lower than those preoperatively(all P&#x003C;0.05). The changes in coma(horizontal)and spherical aberration(SA)at 3mo postoperatively were smaller in the SMILE group [0.106(0.056, 0.171)and 0.115(0.081, 0.182)μm] than in the FS-LASIK group [0.206(0.104, 0.355)and 0.197(0.128, 0.254)μm](Z=-4.170, -5.016, all P&#x003C;0.05). A negative correlation was found between postoperative SA and postoperative RDV-(10°～53°)(rs=-0.205, -0.181, -0.226, -0.244, all P&#x003C;0.05).CONCLUSION: Both FS-LASIK and SMILE reduced retinal hyperopic defocus in the peripapillary macular range of 20°～53° eccentricity, and the postoperative changes in coma(horizontal)and SA were smaller with SMILE than with FS-LASIK. There was a certain correlation between postoperative SA and postoperative retinal peripheral defocus.

A new form of familial platelet disorder caused by germline mutations in RUNX1 in a pedigree / 中华内科杂志

Objective: To investigate the clinical and biological characteristics of familial platelet disorder (FPD) with germline Runt-related transcription factor (RUNX) 1 mutations. Methods: Patients diagnosed with myelodysplastic syndrome (MDS) or acute myeloid leukemia (AML) with RUNX1 mutations from February 2016 to December 2021 in Wuhan No.1 Hospital underwent pedigree analysis and were screened for gene mutations (somatic and germline). Patients diagnosed with FPD with germline RUNX1 mutations were enrolled and evaluated in terms of clinical characteristics and biological evolution. Bioinformatics analysis was used to assess the pathogenicity of mutations and to analyze the effect of mutated genes on the function of the corresponding protein. Results: Germline RUNX1 mutations were detected in three out of 34 patients suffering from MDS/AML who had RUNX1 mutations. A pedigree of FPD with RUNX1 (RUNX1-FPD) c.562A>C and RUNX1 c.1415T>C mutations was diagnosed, and the mutations were of patrilineal origin. Bioinformatics analysis indicated that the locus at positions 188 and 472 in the AML-1G type of RUNX1 was highly conserved across different species, and that variations might influence functions of the proteins. The mutations were evaluated to be highly pathogenic. Of the nine cases with germline RUNX1 mutations: two patients died due AML progression; one case with AML survived without leukemia after transplantation of hemopoietic stem cells; four patients showed mild-to-moderate thrombocytopenia; two cases had no thrombocytopenia. During the disease course of the proband and her son, mutations in RUNX1, NRAS and/or CEBPA and KIT appeared in succession, and expression of cluster of differentiation-7 on tumor cells was enhanced gradually. None of the gene mutations correlated with the tumor were detected in the four cases not suffering from MDS/AML, and they survived until the end of follow-up. Conclusions: RUNX1-FPD was rare. The mutations c.562A>C and c.1415T>C of RUNX1 could be the disease-causing genes for the family with RUNX1-FPD, and these mutations could promote malignant transformation. Biological monitoring should be carried out regularly to aid early intervention for family members with RUNX1-FPD.

Effect of eccentricity of optical treatment zone on retinal defocus after wearing orthokeratology lens / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To observe the effect of eccentricity of the optical treatment zone on retinal defocus after wearing orthokeratology lens for 12mo.METHODS: In this case-control study, a total of 120 myopic patients(120 eyes)who completed the fitting in our hospital from March 2021 to September 2021 and insisted on wearing orthokeratology lenses for 12mo were selected. According to the eccentricity after wearing lenses for 12mo, they were divided into the low eccentricity group(&#x003C;0.5mm, 58 cases, 58 eyes)and the moderate and high eccentricity group(≥0.5mm, 62 cases, 62 eyes). The optical treatment zone diameter(OTZD), eccentricity, axial length(AL), pupil diameter(PD)and refraction difference value(RDV)were evaluated after 12mo of wearing orthokeratology lenses, and the correlation between RDV and eccentricity was analyzed.RESULTS: After wearing orthokeratology lenses for 12mo, AL growth and RDV at 30°～40° and 40°～53° from the fovea were significantly lower in the moderate and high eccentricity group than in the low eccentricity group(all P&#x003C;0.05). In all patients, RDV at 40°～53° from the fovea was positively correlated with AL growth and OTZD(rs=0.544, 0.333, both P&#x003C;0.01), and negatively correlated with eccentricity(rs=-0.224, P=0.014).CONCLUSION: Peripheral retinal defocus is related to eccentricity and OTZD after wearing orthokeratology lenses. The greater eccentricity and the smaller OTZD within a certain range can induce more peripheral retinal myopic defocus, leading to a better control of AL growth.

They were randomly divided into control group and experimental group. A total of 33 patients(66 eyes)in the control group were treated with sodium hyaluronate combined with IPL, and 31 patients(62 eyes)in the experimental group were treated with diquafosol sodium combined with IPL. Ocular symptom scores were performed before each IPL treatment in both groups to examine non-invasive tear breakup time(NIBUT), tear meniscus height, lipid layer grade of tear film, meibomian gland deletion rate and uncorrected visual acuity.RESULTS:After IPL treatment, ocular symptom scores and meibomian gland deletion rate score of two groups were decreased continuously. NIBUT, tear meniscus height and lipid layer grade of tear film were increased continuously, and there was no significant change in uncorrected visual acuity. NIBUT of patients in the experimental group was better than that in the control group before the third IPL treatment(6.24±0.27s vs. 5.51±0.24s, P=0.046).CONCLUSIONS:Both diquafosol sodium and sodium hyaluronate combined with IPL showed good therapeutic effect on MGD dry eye, but there was no significant difference in the short-term efficacy between the two groups.

Comparison of visual quality after refractive surgery between smart pulse technology-assisted transepithelial photorefractive keratectomy of 1 050Hz ablation frequency and small incision lenticule extraction / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the visual quality between smart pulse technology-assisted(SPT)transepithelial photorefractive keratectomy(TransPRK)of 1 050Hz ablation frequency and small incision lenticule extraction(SMILE)for myopia and astigmatism.METHODS: A total of 138 cases(248 eyes)who received corneal refractive surgery in the Eye Hospital of Chengdu University of TCM were enrolled from July 2020 to January 2021. The patients were divided into TransPRK group(64 cases, 123 eyes)and SMILE group(74 cases, 125 eyes)according to the surgical method. The follow-up duration was 6mo. Strehl ratio(SR)and high-order aberration at 6mm pupil diameter measured by Sirius anterior segment integrated analyzer and LogMAR visual acuity were recorded at different preoperative and postoperative time points.RESULTS: The uncorrected visual acuity(UCVA)of TransPRK group was worse than SMILE group at 1wk and 1mo after surgery(all P<0.05), but UCVA was better in TransPRK group at 6mo after surgery(P<0.05). SR in TransPRK group was lower than that in SMILE group at 1wk and 1mo after surgery(all P<0.05). There was no significant difference in SR between the two groups at 3 and 6mo after surgery(P=0.968, 0.433). At 1wk after surgery, there was no significant difference in coma between the two groups(P=0.554). At 1, 3, and 6mo after surgery, coma in the TransPRK group was lower than that in SMILE group(all P<0.05). At 1wk, 1 and 3mo after surgery, the trefoil aberration in TransPRK group was higher than that in SMILE group(all P<0.05). At 6mo after surgery, there was no significant difference in trefoil aberration between the two groups(P=0.167). At 6mo after surgery, UCVA of TransPRK group and SMILE group were -0.13±0.05 and -0.11±0.08, respectively, which were better than the best corrected visual acuity(BCVA)before surgery(-0.07±0.05 and -0.07±0.05; all P<0.05). Furthermore, the SR of both groups was higher than that before surgery(all P<0.05).CONCLUSION: Both SPT-assisted TransPRK of 1 050Hz ablation frequency and SMILE can achieve better visual acuity after refractive surgery, while SMILE has better visual quality at 1wk and 1mo after surgery. However, SPT-assisted TransPRK of 1 050Hz ablation frequency has better visual acuity at 6mo after surgery than SMILE, and the coma is smaller.
