ObjectiveTo investigate the effect and underlying mechanism of the Wulao Qisun prescription on pathological new bone formation in ankylosing spondylitis （AS）. MethodsSynovial fibroblasts were isolated from the hip joints of AS patients and observed under a microscope to assess cell morphology. The cells were identified using immunofluorescence staining. The isolated AS fibroblasts were divided into blank group， low drug-containing serum group， medium drug-containing serum group， high drug-containing serum group， and positive drug group. After drug intervention， cell proliferation was measured using the cell counting kit-8 （CCK-8） assay to observe fibroblast growth and determine the optimal intervention time. Alkaline phosphatase （ALP） activity was measured using the alkaline phosphatase assay. Protein expression of osteocalcin （OCN）， osteopontin （OPN）， and runt-related transcription factor 2 （Runx2） was detected by Western blot. The mRNA expression levels of Wnt5a， β-catenin， and Dickkopf-1 （DKK-1） were measured by real-time quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， each drug-containing serum group of Wulao Qisun prescription and the positive drug group inhibited the proliferation of AS fibroblasts and reduced ALP expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription downregulated β-catenin mRNA expression （P<0.05）. The medium and high drug-containing serum groups and the positive drug group significantly downregulated Wnt5a and β-catenin mRNA expression （P<0.05， P<0.01）， with the positive drug group showing the most pronounced effect （P<0.01）. The high drug-containing serum group and the positive drug group significantly upregulated DKK-1 mRNA expression （P<0.01）. Compared with the blank group， the low drug-containing serum group of Wulao Qisun prescription inhibited the expression of OPN and Runx2 proteins （P<0.05， P<0.01）， while the medium and high drug-containing serum groups and the positive drug group inhibited the expression of OCN， OPN， and Runx2 proteins （P<0.05， P<0.01）. ConclusionThe Wulao Qisun prescription can inhibit the proliferation and osteogenic differentiation of AS fibroblasts， thereby delaying the formation of pathological new bone in AS. The possible mechanism involves the regulation of Wnt/β-catenin-related gene expression， further inhibiting the transcription of downstream target genes.

Objective To analyze the trends in the disease burden of schistosomiasis in China from 1992 to 2021, and to project the disease burden of schistosomiasis in China from 2022 to 2030, so as to provide insights into the elimination of schistosomiasis in China. Methods The prevalence, age-standardized prevalence, disability-adjusted life year (DALYs) rate and age-standardized DALYs rate of schistosomiasis, as well as the years lost due to disability (YLDs) rate and age-standardized YLDs rate of anemia attributable to Schistosoma infections in China, the world and different socio-demographic index (SDI) regions were captured from the Global Burden of Disease Study 2021 (GBD 2021) data resources, and the trends in the disease burden due to schistosomiasis were evaluated with estimated annual percentage change (EAPC) and its 95% confidence interval (CI). In addition, the age, period and cohort effects on the prevalence of schistosomiasis were examined in China using an age-period-cohort (APC) model, and the disease burden of schistosomiasis was predicted in China from 2022 to 2030 using a Bayesian age-period-cohort (BAPC) model. Results The age-standardized prevalence and DALYs rate of schistosomiasis, and the age-standardized YLDs rate of anemia attributable to Schistosoma infections were 761.32/10⁵, 5.55/10⁵ and 0.38/10⁵ in China in 2021. These rates were all lower than the global levels (1 914.30/10⁵, 21.90/10⁵ and 3.36/10⁵, respectively), as well as those in the medium SDI regions (1 413.61/10⁵, 12.10/10⁵ and 1.93/10⁵, respectively), low-medium SDI regions (2 461.03/10⁵, 26.81/10⁵ and 4.48/10⁵, respectively), and low SDI regions (5 832.77/10⁵, 94.48/10⁵ and 10.65/10⁵, respectively), but higher than those in the high SDI regions (59.47/10⁵, 0.49/10⁵ and 0.05/10⁵, respectively) and high-medium SDI regions (123.11/10⁵, 1.20/10⁵ and 0.12/10⁵, respectively). The prevalence and DALYs rate of schistosomiasis were higher among men (820.79/10⁵ and 5.86/10⁵, respectively) than among women (697.96/10⁵ and 5.23/10⁵, respectively) in China in 2021, while the YLDs rate of anemia attributable to Schistosoma infections was higher among women (0.66/10⁵) than among men (0.12/10⁵). The prevalence of schistosomiasis peaked at ages of 30 to 34 years among both men and women, while the DALYs rate of schistosomiasis peaked among men at ages of 15 to 19 years and among women at ages of 20 to 24 years. The age-standardized prevalence of schistosomiasis showed a moderate decline in China from 1992 to 2021 relative to different SDI regions [EAPC = -1.51%, 95% CI: (-1.65%, -1.38%)], while the age-standardized DALYs rate [EAPC = -3.61%, 95% CI: (-3.90%, -3.33%)] and age-standardized YLDs rate of anemia attributable to Schistosoma infections [EAPC = -4.16%, 95% CI: (-4.38%, -3.94%)] appeared the fastest decline in China from1992 to 2021 relative to different SDI regions. APC modeling showed age, period, and cohort effects on the trends in the prevalence of schistosomiasis in China from 1992 to 2021, and the prevalence of schistosomiasis appeared a rise followed by decline with age, and reduced with period and cohort. BAPC modeling revealed that the age-standardized prevalence and age-standardized DALYs rate of schistosomiasis, and age-standardized YLDs rate of anemia attributable to Schistosoma infections all appeared a tendency towards a decline in China from 2022 to 2030, which reduced to 722.72/10⁵ [95% CI: (538.74/10⁵, 906.68/10⁵)], 5.19/10⁵ [95% CI: (3.54/10⁵, 6.84/10⁵)] and 0.30/10⁵ [95% CI: (0.21/10⁵, 0.39/10⁵)] in 2030, respectively. Conclusions The disease burden of schistosomiasis appeared a tendency towards a decline in China from 1992 to 2021, and is projected to appear a tendency towards a decline from 2022 to 2030. There are age, period and cohort effects on the prevalence of schistosomiasis in China. Precision schistosomiasis control is required with adaptations to current prevalence and elimination needs.

Maternal health during pregnancy has a direct impact on the risk and severity of neurodevelopmental disorders (NDDs) in the offspring, especially in the case of drug exposure. However, little progress has been made to assess the risk of drug exposure during pregnancy due to ethical constraints and drug use factors. We collected and manually curated sub-pathways and pathways (sub-/pathways) and drug information to propose an analytical framework for predicting drug candidates. This framework linked sub-/pathway activity and drug response scores derived from gene transcription data and was applied to human fetal brain development and six NDDs. Further, specific and pleiotropic sub-/pathways/drugs were identified using entropy, and sex bias was analyzed in conjunction with logistic regression and random forest models. We identified 19 disorder-associated and 256 regionally pleiotropic and specific candidate drugs that targeted risk sub-/pathways in NDDs, showing temporal or spatial changes across fetal development. Moreover, 5443 differential drug-sub-/pathways exhibited sex-biased differences after filling in the gender labels. A user-friendly NDDP visualization website ( https://ndd-lab.shinyapps.io/NDDP ) was developed to allow researchers and clinicians to access and retrieve data easily. Our framework overcame data gaps and identified numerous pleiotropic and specific candidates across six disorders and fetal developmental trajectories. This could significantly contribute to drug discovery during pregnancy and can be applied to a wide range of traits.

Ankylosing spondylitis （AS） is an inflammatory autoimmune disease with chronic low back pain as the main clinical manifestation， which mainly affects the axial joints， peripheral joints and various organs. In severe cases， the spine is stiff or deformed， which affects the quality of life and health of patients. The pathogenic factors of AS are complex， which are related to heredity， immunity and intestinal flora. The pathogenesis of AS is not clear yet. Among them， inflammatory reaction， bone destruction and heterotopic ossification are the main pathological features of AS， which play an important role in the disease process of AS. Traditional Chinese medicine has multi-target， multi-channel and multi-component pharmacological effects， which can prevent and treat AS by anti-inflammation， inhibiting bone destruction and preventing heterotopic ossification， and the clinical effect is remarkable， but there is no relevant literature report. Therefore， this review expounds the relationship between inflammatory reaction， bone destruction and heterotopic ossification and the occurrence and development of AS， and summarizes the latest research reports of traditional Chinese medicine in treating AS from anti-inflammatory， inhibiting bone destruction and preventing heterotopic ossification， aiming at providing reference and new ideas and directions for further research on the prevention and treatment of AS by traditional Chinese medicine.

Objective To study the clinical effect of Shengjin Yiwei Decoction on chronic heart failure(CHF)complicated with gastrointestinal dysfunction in patients with deficiency of stomach Yin.Methods Totally 68 patients with stomach Yin deficiency syndrome CHF complicated with gastrointestinal dysfunction in our hospital were selected.On the basis of active treatment of heart failure,the control group was treated with omeprazole enteric-soluble capsule,domperidone tablet and pancrease enteric-soluble capsule,and the experimental group was treated with Shengjin Yiwei Decoction.The clinical efficacy of the two groups was compared.traditional Chinese medicine symptom quantification score,gastrointestinal function quantification score,serum gastrin(GAS),plasma motilin(MTL),interleukin(IL)-6 and tumor necrosis factor(TNF)-α levels.Results The effective rate of experimental group was significantly higher than that of control group(χ2=13.73,P<0.05).After treatment,the quantitative score of gastrointestinal dysfunction,quantitative score of TCM symptoms,serum IL-6 and serum TNF-α levels in 2 groups were significantly lower than before treatment,and the above indexes in test group were significantly lower than control group(P<0.05).The levels of serum GAS and plasma MTL in 2 groups were significantly higher than before treatment,and the above indexes in test group were significantly higher than those in control group(P<0.05).Conclusion Shengjin Yiwei Decoction has obvious curative effect on stomach and Yin deficiency syndrome CHF complicated with gastrointestinal dysfunction,can improve clinical manifestations,adjust the level of gastrointestinal hormones and inflammatory factors,and is worthy of clinical application.

Objective:To investigate the image quality, radiation dose, and diagnostic efficiency of the regimen of GE 256-slice Revolution CT low-dose scanning, combined with an individualized contrast agent, in the assessment of coronary in-stent restenosis.Methods:A total of 120 patients (with 142 stents) treated with coronary stent implantation at the Beijing Renhe Hospital from August 2020 to August 2022 were enrolled in this study. They were randomly divided into an observation group (60 cases with 70 stents) and a conventional group (60 cases with 72 stents) using the random number table method. Both groups received GE 256-slice Revolution CT examinations. Patients in the conventional group were injected with 70 ml of iopromide as a contrast agent each, while those in the observation group were given individualized doses based on their body mass indices (BMIs). A tube voltage of 120 kV and a tube current of 534 mA were applied to the conventional group, whereas the tube voltage and current for the observation group were adjusted within the ranges of 80-120 kV and 150-534 mAs based on patients’ BMIs. Both groups received coronary angiography 7-14 d after coronary computed tomography angiography (CCTA). Finally, the CT image quality, radiation dose, iodine intake, and diagnostic efficiency were compared between the two groups.Results:Both groups exhibited no significant differences in CT values, contrast-to-noise ratios, blooming artifacts, and stent diameters of the left main coronary artery ( P > 0.05). The conventional group manifested higher CT dose index, CT dose length product, effective dose, and iodine intake compared to the observation group ( t = 10.30, 8.75, 10.27, 4.60, P < 0.05). With coronary angiography result as the gold standard, the observation and conventional groups yielded Kappa values of 0.904 and 0.879, respectively, suggesting high consistency in diagnostic performance. Additionally, the two groups demonstrated nonsignificant differences in sensitivity and specificity ( P > 0.05). Conclusions:The regimen of GE 256-slice Revolution CT low-dose scanning, combined with an individualized contrast agent, yielding image quality and diagnostic efficiency equivalent to those of the conventional regimen, can effectively reduce radiation dose and iodine intake. Therefore, this regimen merits wide applicability.

Objective:To investigate the stability and feasibility of using absorbable screws during Bernese periacetabular osteotomy.Methods:A retrospective analysis was conducted on a 36 year-old woman diagnosed with developmental dysplasia of the hip, who had undergone Bernese periacetabular osteotomy. Finite element analysis was used to simulate the stability of the acetabulum under loads of 10%, 20%, 50%, and 100% of the patient's weight. The structural stiffness of the pelvis and the maximum equivalent stress on the absorbable screws were observed under different conditions, including whether the acetabular bone block and the ilium were in contact, whether 3 or 4 screws were used, and whether a graft (including fibular cortical bone and PEEK grafts) was used.Results:The structural stiffness of the pelvis fixed with four screws increased by 67%-94% compared to that with three screws. After using a graft, the structural stiffness of the pelvis increased by 50%-83%. As the load increased, the maximum equivalent stress on the screws also increased. When the acetabular bone block and the ilium had no contact, no graft was used, and only three screws were used for fixation, the maximum equivalent stress could reach 518.9 MPa, while this value dropped to 61% when four screws were used (318.7 MPa). When the acetabular bone block and the ilium were in contact, the maximum equivalent stress was about 12% of that when there was no contact, regardless of the number of screws used. When a cortical bone graft or a PEEK graft was used, the maximum equivalent stress could drop to 21%-26% of that without a graft. When the screw strength was 130 MPa, a load of 20% of body weight was applied, and only three screws were used without a graft, the equivalent stress could exceed the strength of the screw; if four screws were used, the equivalent stress was slightly higher than the strength of the screw when a load of 50% of body weight was applied. However, when a graft was used (either cortical bone or PEEK), even when a load of 100% of body weight was applied, the equivalent stress was slightly lower than the strength of the screw.Conclusion:Absorbable screws can provide sufficient stability for Bernese periacetabular osteotomy. The contact between the acetabular bone block and the ilium, an increase in the number of screws, and the use of grafts (cortical bone and PEEK grafts) can further improve stability. Therefore, absorbable screws have broad application prospects in Bernese periacetabular osteotomy.

Objective:To explore the value of ultrasound measuring gastric sinus cross-sectional area (CSA) to guide early individualized enteral nutrition implementation strategies in sepsis patients.Methods:Thirty septic patients admitted to the EICU and comprehensive ICU of The Second Affiliated Hospital of Nanjing University of Chinese Medicine between January 2021 and December 2022 each were included. EICU patients used bedside ultrasound for gastric sinus CSA to guide the implementation of early enteral nutrition in septic patients, and a routine nutritional support strategy was adopted in the integrated ICU. The correlation of CSA and feeding intolerance in patients with septic gastrointestinal dysfunction, the ROC curve and other relevant indicators of gastrointestinal dysfunction gastrointestinal dysfunction score, SOFA score, APACHEⅡ score, intra-abdominal pressure (IAP), serum protein (PA), [albumin (Alb)]. By comparing the indicators related to inflammation, nutritional status and days of ICU stay after different strategies of the two groups, the advantages of different strategies were analyzed.Results:The baseline data of the two groups were balanced and comparable; the incidence of feeding intolerance was significantly higher (36.67%) than the conventional group (10.00%), with aggressive and early individualized treatment, the incidence rate on the third day was only 10.00%, significantly lower than that in the conventional treatment group (40.00%). Treatment up to the 5th day, the related function scores (gastrointestinal dysfunction score, APACHEⅡ score, SOFA score, IAP), nutritional status indicators (5 d hot card reaching the standard rate, PA, Alb) and inflammation indicators (WBC, PCT, hs-CRP) were significantly improved compared with admission, and is better than the conventional treatment group. In addition, the ICU hospital days and the incidence of aspiration were lower in the ultrasound treatment group ( P <0.05). CSA showed favorable correlation with gastrointestinal dysfunction score, APACHEⅡ score, SOFA score, IAP, PA and Alb, correlation coefficients were 0.79、0.60、0.66、0.71、-0.6 and -0.64( P <0.05). The ROC curve for predicting feeding intolerance by CSA showed the AUC was 0.828, 95% CI was 0.737-0.919, its optimal cutoff value for predicted feeding intolerance was 7.835 cm 2, the sensitivity and specificity were 88.20% and 71.80%. Conclusions:Ultrasound measuring CSA can early and effectively found the feeding intolerance in the patients with sepsis , via giving individualized enteral nutrition implementation strategy, significantly improve the organ function score, nutritional status and inflammation index, reduce the ICU hospital days and aspiration, and correlate with the conventional evaluation index, and sensitivity and specificity are high, worthy of the clinical further promotion.
