Metabolic-associated fatty liver disease (MAFLD) and osteoporosis (OP) are two very common metabolic diseases. A growing body of experimental evidence supports a pathophysiological link between MAFLD and OP. MAFLD is often associated with the development of OP. Rutaecarpine (RUT) is one of the main active components of Chinese medicine Euodiae Fructus. Our previous studies have demonstrated that RUT has lipid-lowering, anti-inflammatory and anti-atherosclerotic effects, and can improve the OP of rats. However, whether RUT can improve both fatty liver and OP symptoms of MAFLD mice at the same time remains to be investigated. In this study, we used C57BL/6 mice fed a high-fat diet (HFD) for 4 months to construct a MAFLD model, and gave the mice a low dose (5 mg·kg^-1) and a high dose (15 mg·kg^-1) of RUT by gavage for 4 weeks. The effects of RUT on liver steatosis and bone metabolism were then evaluated at the end of the experiment [this experiment was approved by the Experimental Animal Ethics Committee of Institute of Medicinal Biotechnology, Chinese Academy of Medical Sciences (approval number: IMB-20190124D₃03)]. The results showed that RUT treatment significantly reduced hepatic steatosis and lipid accumulation, and significantly reduced bone loss and promoted bone formation. In summary, this study shows that RUT has an effect of improving fatty liver and OP in MAFLD mice.

OBJECTIVE: To explore the application effect of self-developed anatomical main nail insertion guide in proximal femoral nail antirotation (PFNA) internal fixation for the treatment of intertrochanteric fractures (IFF) in elderly patients. METHODS: A retrospective analysis was performed on 62 patients with AO31-A2 intertrochanteric fractures who underwent PFNA surgery and met the inclusion criteria from January 2022 to December 2024. They were divided into the conventional PFNA insertion group (conventional operation group) and the anatomical main nail insertion guide-assisted PFNA insertion group(guide group). The conventional operation group (PFNA) included 31 patients, 14 males and 17 females, the age ranged from 64 to 90 with an average of (75.2±11.6) years old;the guide group (PFNA) included 31 patients, 10 males and 21 females, the age ranged fron 67 to 97 with an average of (78.6±13.4) years old. The incision length of the main nail entry, the number of fluoroscopies from satisfactory reduction to before main nail insertion, operation time, intraoperative blood loss, 3-day postoperative VAS score, postoperative hip function Harris score, complications, etc. were observed and compared between the two groups. RESULTS: All patients were followed up for a period ranging from 4 to 12 months, with an average follow-up duration of (6.8±1.6) months. Compared with the guide group, the conventional operation group showed significant differences in the following parameters:the entrance length of the main screw was (6.74±3.77) cm vs. (5.13±1.31) cm, the number of fluoroscopies before the insertion of the main screw was (10.32±3.08) times vs. (7.71±2.41) times, the operation time was (150.45±53.47) minutes vs. (127.48±30.37) minutes, and the intraoperative blood loss was (196.77±121.06) ml vs. (140.97±86.00) ml, with P<0.05 indicating statistical significance.There was no statistically significant difference in 3-day postoperative VAS between the two groups (P>0.05). There was a statistically significant difference in the Harris scores between the conventional operation group and the guided operation group one month post-surgery (60.61±6.60) vs. (65.48±5.19) points (P<0.05). and there was no statistically significant difference in hip Harris scores between the two groups at 3 months after operation (P>0.05). During the 3-month follow-up after operation, neither group had incision infection, screw loosening, cutting, pressure sores, deep vein thrombosis, etc., and there was no statistically significant difference in the complication rate between the two groups. CONCLUSION It is quickly and accurately to implant PFNA assisted by the anatomical major nail implant guide in treatment of osteoporotic intertrochanteric fracture in the elderly.Compared with the traditional operation, it can shorten the operation time and reduce the surgical and X-ray trauma, and beneficial to the rapid rehabilitation of patients.

BACKGROUND: Our understanding of the correlation between postdischarge cancer and mortality in patients with coronary artery disease (CAD) remains incomplete. The aim of this study was to investigate the relationships between postdischarge cancers and all-cause mortality and cardiovascular mortality in CAD patients. METHODS: In this retrospective cohort study, 25% of CAD patients without prior cancer history who underwent coronary artery angiography between January 1, 2011 and December 31, 2015, were randomly enrolled using SPSS 26.0. Patients were monitored for the incidence of postdischarge cancer, which was defined as cancer diagnosed after the index hospitalization, survival status and cause of death. Cox regression analysis was used to explore the association between postdischarge cancer and all-cause mortality and cardiovascular mortality in CAD patients. RESULTS: A total of 4085 patients were included in the final analysis. During a median follow-up period of 8 years, 174 patients (4.3%) developed postdischarge cancer, and 343 patients (8.4%) died. A total of 173 patients died from cardiovascular diseases. Postdischarge cancer was associated with increased all-cause mortality risk (HR = 2.653, 95% CI: 1.727-4.076, P < 0.001) and cardiovascular mortality risk (HR = 2.756, 95% CI: 1.470-5.167, P = 0.002). Postdischarge lung cancer (HR = 5.497, 95% CI: 2.922-10.343, P < 0.001) and gastrointestinal cancer (HR = 1.984, 95% CI: 1.049-3.750, P = 0.035) were associated with all-cause mortality in CAD patients. Postdischarge lung cancer was significantly associated with cardiovascular death in CAD patients (HR = 4.979, 95% CI: 2.114-11.728, P < 0.001), and cardiovascular death was not significantly correlated with gastrointestinal cancer or other types of cancer. CONCLUSIONS Postdischarge cancer was associated with all-cause mortality and cardiovascular mortality in CAD patients. Compared with other cancers, postdischarge lung cancer had a more significant effect on all-cause mortality and cardiovascular mortality in CAD patients.

Thoracic aortic aneurysm (TAA) significantly endangers the lives of individuals with Marfan syndrome (MFS), yet the intricacies of their biomechanical origins remain elusive. Our investigation delves into the pivotal role of hemodynamic disturbance in the pathogenesis of TAA, with a particular emphasis on the mechanistic contributions of the mammalian target of rapamycin (mTOR) signaling cascade. We uncovered that activation of the mTOR complex 1 (mTORC1) within smooth muscle cells, instigated by the oscillatory wall shear stress (OSS) that stems from disturbed flow (DF), is a catalyst for TAA progression. This revelation was corroborated through both an MFS mouse model (Fbn1 ^+/C1039G) and clinical MFS specimens. Crucially, our research demonstrates a direct linkage between the activation of the mTORC1 pathway and the intensity in OSS. Therapeutic administration of rapamycin suppresses mTORC1 activity, leading to the attenuation of aberrant SMC behavior, reduced inflammatory infiltration, and restoration of extracellular matrix integrity-collectively decelerating TAA advancement in our mouse model. These insights posit the mTORC1 axis as a strategic target for intervention, offering a novel approach to manage TAAs in MFS and potentially pave insights for current treatment paradigms.

Objective To investigate the risk factors for bronchopulmonary dysplasia(BPD)in twin preterm infants with a gestational age of<34 weeks,and to provide a basis for early identification of BPD in twin preterm infants in clinical practice.Methods A retrospective analysis was performed for the twin preterm infants with a gestational age of<34 weeks who were admitted to 22 hospitals nationwide from January 2018 to December 2020.According to their conditions,they were divided into group A(both twins had BPD),group B(only one twin had BPD),and group C(neither twin had BPD).The risk factors for BPD in twin preterm infants were analyzed.Further analysis was conducted on group B to investigate the postnatal risk factors for BPD within twins.Results A total of 904 pairs of twins with a gestational age of<34 weeks were included in this study.The multivariate logistic regression analysis showed that compared with group C,birth weight discordance of>25%between the twins was an independent risk factor for BPD in one of the twins(OR=3.370,95%CI:1.500-7.568,P<0.05),and high gestational age at birth was a protective factor against BPD(P<0.05).The conditional logistic regression analysis of group B showed that small-for-gestational-age(SGA)birth was an independent risk factor for BPD in individual twins(OR=5.017,95%CI:1.040-24.190,P<0.05).Conclusions The development of BPD in twin preterm infants is associated with gestational age,birth weight discordance between the twins,and SGA birth.

Objective To analyze the characteristics and malignancy of red-patch like lesion(RPL)during cystoscopy,and to explore the significance of RPL biopsy.Methods Clinical data of patients who had RPL detected in our hospital during Jan.2019 and Jun.2023 were retrospectively analyzed,including gender,age,cause of examination,presence of scars,complications and biopsy pathology.The patients were divided into the benign and malignant groups,and their clinical and RPL characteristics were analyzed.Results A total of 521 cases of RPL were enrolled including 416(79.8％)benign cases,and 105(20.2％)malignant cases.The averae age of the malignant group was higher than the benign group's[(66.8±12.2)years vs.(62.8±12.9)years,P=0.005].The malignant detection rate of RPL in postoperative follow-up patients,those with hematuria and those with lower urinary tract symptoms was 23.7％(92/389),19.6％(9/46),4.7％(4/86),respectively.According to direct observation and experience,the detection rate of pathological malignancy in the three groups of patients with high suspicion of RPL malignancy,mild suspicion of RPL malignancy and high probability of benign was 56.9％(37/65),37.0％(30/81)and 10.1％(38/375),respectively.Conclusion Once RPL is detected during cystoscopy,active biopsy should be performed.For elderly male patients undergoing postoperative follow-up,RPL biopsy is particularly important,especially when the lesion is located on or near the scar surface.

Background/Aims: The histological characteristics and natural history of precirrhotic primary biliary cholangitis (PBC) with portal hypertension (PH) are unclear. Our aim was to clarify the prevalence, risk factors, and histological characteristics of precirrhotic PBC patients with PH. Methods: This retrospective study compared the clinical features, histological characteristics, and response to ursodeoxycholic acid (UDCA) between the PH and non-PH groups of precirrhotic PBC patients. Results: Out of 165 precirrhotic PBC patients, 40 (24.2%) also had PH. According to histological stage 1, 2 and 3 disease, 5.3% (1/19), 17.3% (17/98), and 45.8% (22/48) of patients also had PH, respectively. Precirrhotic PBC with PH was significantly positively correlated with bile duct loss, degree of cytokeratin 7 positivity, and degree of fibrosis in the portal area, but significantly negatively correlated with lymphoid follicular aggregation. Compared to the non-PH group, patients in the PH group showed a higher prevalence of obliterative portal venopathy, incomplete septal fibrosis, portal tract abnormalities and non-zonal sinusoidal dilatation (p<0.05). In addition, patients with PH were more likely to present with symptoms of jaundice, ascites, epigastric discomfort, a poorer response to UDCA, and more decompensation events (p<0.05). High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values were risk factors for precirrhotic PBC with PH. Conclusions Approximately 24.2% of precirrhotic PBC patients have PH, which is histologically related to the injury of bile ducts. High alkaline phosphatase levels, low white blood cell counts, high Mayo scores, and high FIB-4 index values are associated with increased risk of precirrhotic PBC with PH.

The application of new-generation information technologies such as big data, the internet of things(IoT), and cloud computing in the traditional Chinese medicine(TCM)manufacturing industry is gradually deepening, driving the intelligent transformation and upgrading of the TCM industry. At the current stage, there are challenges in understanding the extraction process and its mechanisms in TCM. Online detection technology faces difficulties in making breakthroughs, and data throughout the entire production process is scattered, lacking valuable mining and utilization, which significantly hinders the intelligent upgrading of the TCM industry. Applying data-driven technologies in the process of TCM extraction can enhance the understanding of the extraction process, achieve precise control, and effectively improve the quality of TCM products. This article analyzed the technological bottlenecks in the production process of TCM extraction, summarized commonly used data-driven algorithms in the research and production control of extraction processes, and reviewed the progress in the application of data-driven technologies in the following five aspects: mechanism analysis of the extraction process, process development and optimization, online detection, process control, and production management. This article is expected to provide references for optimizing the extraction process and intelligent production of TCM.

OBJECTIVE: To compare the clinical efficacy of acupuncture with different frequencies in the treatment of patients with functional dyspepsia (FD). METHODS: A total of 90 patients with FD were randomly divided into a 3-time acupuncture treatment per week group (3-A group, 31 cases, 2 cases dropped off), a 1-time acupuncture treatment per week group (1-A group, 30 cases, 2 cases dropped off) and a control group (29 cases, 2 cases dropped off). In the two acupuncture groups, the acupoints were Zhongwan (CV 12) and bilateral Tianshu (ST 25), Neiguan (PC 6), Liangqiu (ST 34), Yanglingquan (GB 34), Zusanli (ST 36) and Taichong (LR 3), stimulated 3 times a week and once a week, respectively; and the treatment was given consecutively for 4 weeks. In the control group, no intervention was adopted, but the compensatory therapy was provided after the end of follow-up. The scores of the symptom index of dyspepsia (SID), self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were compared among the 3 groups before treatment, after 4 weeks of treatment and in 4 and 8 weeks after treatment completion separately. The score of Nepean dyspepsia life quality index (NDLQI) was evaluated before treatment, after 2 and 4 weeks of treatment and in 4 and 8 weeks after treatment completion. RESULTS: After 4 weeks of treatment and in 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS were all reduced in the 3-A group and the 1-A group when compared with the scores before treatment (P<0.000 1, P<0.05). After 4 weeks of treatment, the scores of SID, SAS and SDS in the two acupuncture groups were lower than those in the control group (P<0.000 1). After 2 and 4 weeks of treatment, the increased values of NDLQI score in the two acupuncture groups were all higher than those in the control group (P<0.05). In 4 and 8 weeks after treatment completion, the scores of SID, SAS and SDS in the 3-A group were lower than those in the 1-A group (P<0.001, P<0.05), and the increased values of NDLQI score in the 3-A group were higher than those in the 1-A group (P<0.000 1). CONCLUSION Acupuncture given 3 times per week is superior to the treatment given once per week in the aspects of relieving the clinical symptoms, improving the quality of life and regulating the emotional state in patients with FD. This efficacy is persistent for 8 weeks after treatment completion.

Objective:To observe any effect of supplementing conventional rehabilitation training with repeated transcranial magnetic stimulation (rTMS) in the treatment of lumbar disc herniation (LDH).Methods:Seventy-two LDH patients were randomly divided into an rTMS group ( n=24), a training group ( n=24), and a combined group ( n=24). The rTMS group received 2Hz rTMS at an intensity of 80% resting motor threshold with a total of 1000 pulses, the training group was given Mackenzie therapy and lumbar core muscle stability training, while the combined group was provided with both. Each group was treated once a day, 6 times a week for 8 weeks. The participants rated their pain using a visual analog scale (VAS), and the Oswestry dysfunction index (ODI) was also used to evaluate the degree of pain and dysfunction in all three groups before and right after the treatment, as well as 8 weeks later. After the treatment, its therapeutic effect was evaluated using the improved Macnab standard. Each patient was followed up for 12 months and any recurrence was recorded. Results:Before treatment there was no significant difference in average VAS ratings or ODI scores among the three groups. Afterward, pain and dysfunction were relieved significantly in all three groups. Compared with the rTMS group, the average VAS rating in the training group was significantly higher and the average ODI score was significantly lower after the treatment and during the follow-up. Moreover, the average VAS rating and ODI score of the combined group were significantly lower than those in the other two groups after the treatment and during follow-up. The total effectiveness rate in the rTMS group was assessed as 62.5% compared with 95.8% in the training group and 100% in the combined group-a significant difference for the rTMS group. Follow-up showed that the recurrence rates of the rTMS group, training group and combined group were 37.5%, 25% and 8.3%, respectively-a significant difference in the case of the combined group.Conclusion:rTMS combined with rehabilitation training can relieve pain, improve lumbar function and reduce the recurrence of LDH.
