BACKGROUND: The American Heart Association recently released a new cardiovascular health (CVH) metric, Life's Essential 8 (LE8), for health promotion. However, the association between LE8 scores and the risk of chronic kidney disease (CKD) remains uncertain. We aimed to explore the association of LE8 scores with new-onset CKD and examine whether socioeconomic deprivation and genetic risk modify this association. METHODS: A total of 286,908 participants from UK Biobank and without prior CKD were included between 2006 and 2010. CVH was categorized using LE8 scores: low (LE8 scores <50), moderate (LE8 scores ≥50 but <80), and high (LE8 scores ≥80). The study outcome was new-onset CKD, ascertained by data linkage with primary care, hospital inpatient, and death data. Cox proportional hazard regression models were used to investigate the association between CVH categories and new-onset CKD. RESULTS: During a median follow-up of 12.5 years, 8857 (3.1%) participants developed new-onset CKD. Compared to the low CVH group, the moderate (adjusted hazards ratio [HR], 0.50; 95% confidence interval [CI]: 0.47-0.53) and high CVH (adjusted HR, 0.31; 95% CI: 0.27-0.34) groups had a significantly lower risk of developing new-onset CKD. The population-attributable risk associated with high vs. intermediate or low CVH scores was 40.3%. Participants who were least deprived ( vs.  most deprived; adjusted HR, 0.75; 95% CI: 0.71-0.79) and with low genetic risk of CKD ( vs.  high genetic risk; adjusted HR, 0.89; 95% CI: 0.85-0.94) had a significantly lower risk of developing new-onset CKD. However, socioeconomic deprivation and genetic risks of CKD did not significantly modify the relationship between LE8 scores and new-onset CKD (both P -interaction >0.05). CONCLUSION Achieving a higher LE8 score was associated with a lower risk of developing new-onset CKD, regardless of socioeconomic deprivation and genetic risks of CKD.

Objective To analyze the predictive value of serum levels of procalcitonin(PCT)and cytokines on the prognosis of patients with COVID-19 at admission.Methods From November 2022 to February 2023,patients diagnosed with COVID-19 who were admitted to Beijing Chest Hospital were enrolled.Chemiluminescence was used to detect serum PCT levels,and flow microsphere array was used to detect serum cytokines IL-1β,IL-2,IL-4,IL-5,IL-6,IL-8,IL-10,IL-12p70,IL-17A,IL-17F,IL-22,TNF-α,TNF-β,IFN-γ level.ICU admission,mechanical ventilation and in-hospital death were defined as poor prognosis.After excluding patients with bacterial infection,the relationship between serum PCT and cytokine levels at admission and the prognosis of COVID-19 patients was analyzed.After excluding patients with bacterial infection,the relationship between serum PCT and cytokine levels at admission and the prognosis of COVID-19 patients was analyzed.Results A total of 176 patients with complete data were included,including 134 in the PCT-normal group and 42 in the PCT-elevated group,with a median age of 71.50 years and 71.59%males.Patients in the PCT elevated-group had significantly higher rates of ICU admission(38.41%vs.13.11%,P<0.05),mechanical ventilation(76.92%vs.24.59%,P<0.001)and in-hospital mortality(38.46%vs.6.56%,P<0.001)were significantly higher than those in the PCT-normal group.Serum levels of cytokines IL-6(7.40 pg/mL vs.4.78 pg/mL,P = 0.033 4)and IL-8(10.97 pg/mL vs.5.92 pg/mL,P<0.001)were significantly higher in patients with poor prognosis than in those with good prognosis.The area under the curve for PCT,IL-6,and IL-8 to predict poor prognosis in COVID-19 patients was 0.687,0.660,and 0.746,respectively;sensitivity was 52.78%,55.17%,and 72.41%,respectively;and specificity was 81.58%,74.19%,and 74.19%,respectively,as calculated from the ROC curve.When PCT,IL-6 and IL-8 jointly predict the prognosis of COVID-19 patients,the area under the curve is 0.764,the sensitivity is 70.00%,and the specificity is 80.00%.Conclusion Serum PCT and cytokines IL-6 and IL-8 could be used as predictive markers for poor prognosis in patients with COVID-19.

Objective To study changes in immune cells and cytokines during the reactivation stage of varicella-zoster virus(VZV)in patients with herpes zoster.Methods A total of 50 patients with herpes zoster and 30 healthy individuals were selected from Xi'an Ninth Hospital between May 2022 and October 2022.Flow cytometry was used to detect the proportion of peripheral blood CD3+cells,CD4+cells,CD8+T cells,B cells and NK cells,as well as levels of cytokines IL-2,IFN-γ,IL-10 and IL-6.We analyzed the immune mechanism of VZV reactivation stage in herpes zoster patients.Results Compared with the healthy control group,the proportion of CD3+cells and CD4+T cells in herpes zoster patients decreased significantly;the proportion of NK cells significantly increased;the levels of IFN-γ,IL-10 and IL-6 significantly increased;the proportion of CD8+T cells,B cells and IL-2 content showed an increasing trend,but there was no significant difference.In addition,the severity of neurological involvement in herpes zoster patients might affect changes in cytokine levels.Conclusion During the reactivation period of VZV,changes in the proportion of immune cells and cytokine expression levels are closely related to the occurrence and development of herpes zoster.

The set of guidelines for the diagnosis and treatment of thyroid nodules and differentiated thyroid cancer (the second edition) was published in 2023 in China. Based on the first (2012) edition, the current set was revised jointly by nearly 100 experts in endocrinology, thyroid surgery, oncology, nuclear medicine, ultrasound medicine, and pathology from seven national societies for one year. The new version of the guideline is still divided into two parts, namely, thyroid nodules and differentiated thyroid cancer. The writing mode of asking clinical questions, explaining and giving recommendations is adopted, and a total of 117 recommendations are provided. This article aims to compare the variations in the differentiation of benign and malignant thyroid nodules and surgical treatment of differentiated thyroid cancer between the new and old versions from the perspective of surgery. The author's own understanding and experiences are also discussed.

Objective:To explore the clinical characteristics and related socio-demographic factors of schizo-phrenia patients with different ages of onset.Methods:Totally 2 016 patients with schizophrenia aged 15 to 70 were selected according to the diagnostic criteria for schizophrenia in the Diagnostic and Statistical Manual of Mental Disorders,Fifth Edition.All of the patients were interviewed by psychiatrists using the Mini International Neuropsy-chiatric Interview to diagnose schizophrenia,Clinical-Rated Dimensions of Psychosis Symptom Severity(CRDPSS)and the Positive and Negative Syndrome Scale(PANSS)to assess symptoms.The cut-off points were 18 and 25 years old for three age groups,i.e.early onset(EOS),youth onset(YOS)and adult onset(AOS).Statistical analy-ses were performed by analysis of variance Pearson correlation analysis,and multivariate linear regression.Results:The early-onset patients had the highest total PANSS score(73.8±28.0)and CRDPSS score(11.7±5.4).Fe-male gender,high education level,Han ethnicity,early onset age,and slower onset of illness were negatively corre-lated with the total and dimension score of PANSS scale and CRDPSS scale(standardized regression coefficient:0.04-0.47),and income level and smoking were negatively correlated with those score(standardized regression coefficient:-0.04--0.14).Conclusion:Early-onset schizophrenia patients have more severe symptoms,and fe-male,high education level,early-onset disease,and chronic onset are the risk factors of symptom severity in patients with schizophrenia.

Objective To observe the effects of wheat grain moxibustion for"Huantiao"on sciatic nerve function,pathological morphology of sciatic nerve stem and expressions of TLR4/MyD88/NF-κB signaling pathway expression in spinal cord tissue of rats with sciatic nerve injury(SNI);To explore the possible mechanism of wheat grain moxibustion for the treatment of SNI.Methods Totally 24 SD male rats were randomly divided into blank group,sham-operation group,model group and wheat grain moxibustion group,with 6 rats in each group.The model group and the wheat grain moxibustion group used a rat model with sciatic nerve clamping injury.From the 7th day after modeling,the rats were treated with moxibustion on the affected side of"Huantiao"for 6 strokes each time,once a day,for consecutive 10 days.The sciatic nerve function index(SFI)of rats on the 7th day after modeling and after intervention were observed,mechanical withdraw threshold(MWT)in rats were measured using a fiber optic pain gauge,ELISA was used to detect NO and iNOS content in spinal cord tissue,HE staining was used to observe the morphology of sciatic nerve stem,the expression of TLR4,NF-κBp65,p-NF-κBp65,MyD88,IκBα and p-IκBα in spinal cord tissue were detected by Western blot.Results Compared with the sham-operation group,the SFI and MWT of the rats in the model group significantly decreased(P<0.01),the arrangement of nerve fibers in sciatic nerve stem was disordered,with a significant increase in the number of Schwann cells and a large number of vacuolar degeneration,the content of NO,iNOS and the expression of TLR4,p-NF-κBp65,MyD88,p-IκBα protein in spinal cord tissue significantly increased(P<0.01).Compared with the model group,the SFI and MWT of the rats in the wheat grain moxibustion group increased significantly(P<0.01),the damage of sciatic nerve stem was reduced,with orderly cell arrangement,a decrease in the number of Schwann cells,and a decrease in axonal demyelination and cellular vacuolar degeneration,the content of NO,iNOS and the expression of TLR4,p-NF-κBp65,MyD88,p-IκBα in spinal cord tissue significantly decreased(P<0.05).Conclusion Wheat grain moxibustion for"Huantiao"can down-regulate TLR4,p-NF-κBp65,MyD88 and p-IκBα protein expressions in spinal cord tissue of SNI rats,reduce the secretion of NO and iNOS,thereby relieve pain and damaged nerve tissue inflammation response.

Objective:To study the in vitro construction of functional and self-renewing cartilage organoids based on cartilage acellular extracellular matrix (ECM) microcarriers.Methods:Fresh porcine articular cartilage was taken. The merely crushed cartilage particles were set as natural cartilage group and ECM microcarriers of appropriate particle size, which were prepared by the acellular method of combining physical centrifugation and chemical extraction, were set as microcarrier group. Cartilage organoids were constructed by loading human umbilical cord mesenchymal stem cells (hUCMSCs) and human chondrocytes (hCho) with a ratio of 3∶1 with microcarriers through a rotating bioreactor. The organoids with different induction times were divided into 0-, 7-, 14-, and 21-day induction groups. The cell residues of the microcarrier group and natural cartilage group were evaluated by 4′, 6-diaminidine 2-phenylindole (DAPI) fluorescence staining and DNA quantitative analysis. The retention of microcarrier components was observed by Safranin O and toluidine blue stainnings, and the collagen and glycosaminoglycan (GAGs) levels in the microcarrier group and the natural cartilage group were determined by colorimetric method and dimethyl-methylene blue (DMMB) method. The microcarriers were further characterized by scanning electron microscopy and energy dispersive spectroscopy. The hUCMSCs cultured with Dulbecco′s Modified Eagle′s Medium (DMEM) supplemented with fetal bovine serum (FBS) in a volume fraction of 10% was used as the control group and the hUCMSCs cultured with the microcarrier extract was used as the experimental group. Subgroups of hUCMSCs cultured at 3 time points: 1, 3 and 5 days were set up in the two groups separately. Cell Counting Kit 8 (CCK-8) was used to detect the biocompatibility of the two groups. The cellular activity of the organoids of the 0-, 7-, 14-, and 21-day induction groups was detected by live/dead staining and the self-renewal ability of the cartilage organoids of the 14-day induced group was identified by Ki67 fluorescence staining. The organoids of the 7-, 14-, and 21-day induction groups were detected by RT-PCR in terms of the expression levels of chondrogenesis-related marker aggrecan (ACAN), type II collagen (COL2A1), SRY-related high mobility group-box gene-9 (SOX9), cartilage hypertrophy-and mineralization-related marker type I collagen (COL1A1), Runt-related transcription factor-2 (RUNX2), and osteocalcin (OCN). Colorimetric and DMMB assays were performed to determine the ability of organoids in the 0-, 7-, 14-, and 21-day induction groups to secrete collagen and GAGs.Results:The results of DAPI fluorescent staining showed that the natural cartilage group had a large number of nuclei while the microcarrier group hardly had any nuclei. The DNA content of the microcarrier group was (7.8±1.8)ng/mg, which was significantly lower than that of the natural cartilage group [(526.7±14.7)ng/mg] ( P<0.01). Saffranin O and toluidine blue staining showed that the microcarrier was dark- and uniform-colored and it kept a lot of cartilage ECM components. The collagen and GAGs contents of the microcarrier group were (252.9±1.4)μg/mg and (173.4±0.8)μg/mg, which were significantly lower than those of the natural cartilage group [(311.9±2.2)μg/mg and (241.3±0.7)μg/mg] ( P<0.01). Scanning electron microscopy showed that the surface of the microcarriers had uneven and interleaved collagen fiber network. The results of energy spectrum analysis showed that elements C, O and N were evenly distributed in the microcarriers, indicating that the composition of the microcarrier was uniform. The microcarrier had good biocompatibility and there was no statistical significance in the results of CCK-8 test between the control group and the experimental group after 1 and 3 days of culture ( P>0.05). After 5 days of culture, the A value of the experimental group was 0.53±0.02, which was better than that of the control group (0.44±0.03) ( P<0.05). In the 0-, 7-, 14-, and 21-day induction groups, hUCMSCs and hCho were attached to the surface of the microcarriers, with good cellular activity, and the live/death rates were (70.6±1.1)%, (80.5±0.6)%, (94.5±0.9)%, and (90.8±0.5)% respectively ( P<0.01). There were a large number of Ki67 positive cells in cartilage organoids. RT-PCR showed that the expression levels of ACAN, COL2A1, SOX9, COL1A1, RUNX2 and OCN were 1.00±0.09, 1.00±0.24, 1.00±0.18, 1.00±0.03, 1.00±0.06 and 1.00±0.13 respectively in the 7-day induction group; 4.16±0.28, 5.09±1.25, 5.65±1.05, 0.47±0.01, 1.68±0.02 and 0.21±0.06 respectively in the 14-day induction group; 13.42±0.92, 3.07±0.21, 1.84±1.08, 2.72±0.17, 2.91±0.18 and 3.32±1.20 respectively in the 21-day induction group. Compared with the 7-day induction group, the expression levels of ACAN, COL2A1, SOX9 and RUNX2 in the 14-day group were increased ( P<0.05), but COL1A1 expression level was decreased ( P<0.05), with no significant difference in OCN expression level ( P>0.05). Compared with the 7-day induction group, the expression levels of ACAN, COL1A1 and RUNX2 in the 21-day induction group were significantly increased ( P<0.01), with no significant differences in the expression levels of COL2A1, SOX9 and OCN ( P>0.05). Compared with the 14-day induction group, the expression levels of ACAN, COL1A1, RUNX2 and OCN in the 21-day group were increased ( P<0.05 or 0.01), with no significant difference in the expression level of COL2A1 ( P>0.05), but the expression level of SOX9 was decreased ( P<0.05). The contents of collagen in 0-, 7-, 14-and 21-day induction groups were (219.15±0.48)μg/mg, (264.07±1.58)μg/mg, (270.83±0.84)μg/mg and (280.01±0.48)μg/mg respectively. The GAGs contents were (171.18±1.09)μg/mg, (184.06±1.37)μg/mg, (241.08±0.84)μg/mg and (201.14±0.17)μg/mg respectively. Compared with the 0-day induction group, the contents of collagen and GAGs in 7-, 14-, and 21-day induction groups were significantly increased ( P<0.01), among which the content of collagen was the lowest in 7-day induction group ( P<0.01) but the highest in the 21-day induced group ( P<0.01); the content of GAGs was the lowest in the 7-day induced group ( P<0.01) but the highest in the 14-day induction group ( P<0.01). Conclusions:The microcarriers prepared by combining physical and chemical methods are decellularized successfully, with more matrix retention, uniform composition and on cytotoxicity. By loading microcarriers with hUCMSCs and hCho, cartilage organoids are successfully constructed in vitro, which are characterized by good cell activity, self-renewal ability, strong expression of genes related to chondrogenesis and secretion of collagen and GAGs. The cartilage organoids constructed at 14 days of induction have the best chondrogenic activity.

Objectives:To compare the effects of 3D-printed personalized guiding template and robot-assisted pedicle screw placements in orthopedic surgery for adult degenerative scoliosis(ADS).Methods:Retrospective analysis was conducted on 18 ADS patients hospitalized and treated with corrective surgery in the department between January 2020 and December 2022.There were 3 males and 15 females,aged 46-73(63.2±8.2)years old.A total of 236 pedicle screws were placed,and the patients were divided into two groups according to the auxiliary screw placement methods:the 3D-printed personalized guiding template group(3D-printed group,1 1 cases,142 pedicle screws were placed)and robot-assisted screw placement group(Robot group,7 cases,94 pedicle screws were placed).The patients were followed up for 6 months and more.The vertex rotation angle and scoliosis Cobb angle were measured and compared between groups before operation.All pedicle screws were classified by Gertzbein-Robbins classification standard at 1 week after operation,and the accuracy and satisfaction of screw placement in the two groups were compared;And the operative time and incidence of complications were also analyzed and compared between the two groups.Re-sults:The 3D-printed group was not statistically different from the robot group in terms of age(63.6±9.0 years vs.62.6±7.3 years),gender ratio(male/female:2/9 vs.1/6),number of screws placed(12.91±3.83 vs.13.43± 3.60),Cobb angle(40.36°±1 1.82° vs.38.14°±12.84°),and vertex rotation angle(30.27°±7.25° vs.29.86°±9.65°),respectively(P＞0.05).The robot group was longer in operative time than that of 3D-printed group(354.29± 53.73min vs.282.27±73.87min,P＜0.05).Of the total 142 pedicle screws placed in the 3D-printed group,128 screws were of class A,10 were of class B,and 4 were of class C;Of the total 94 pedicle screws placed in the robot group,86 screws were of class A,5 were of class B,and 3 were of class C;No class D or E screws in the two groups.The accuracy rate of screw placement(90.14％)and satisfaction rate(97.18％)of the 3D-printed group were not statistically different from the accuracy rate(91.49％)and satisfaction rate(96.81％)of the robot group,respectively(P＞0.05).The incidence of complications in the 3D-printed group(36.36％)was not significantly different from that in the robot group(57.14％,P＞0.05).Conclusions:Both auxiliary screw placement methods can assist spinal surgeons to accurately place screws in ADS patients,but 3D-printed personalized guiding template needs less time in screw placement.
