Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

Objective To analyze the epidemiological characteristics of hand, foot, and mouth disease (HFMD) in Shanxi Province from 2012 to 2024, and predict the incidence trend for 2025, and to provide a scientific basis for the formulation of prevention and control strategies. Methods Based on the surveillance data of HFMD in Shanxi Province from 2012 to 2024, the spatial and temporal distribution characteristics and time trends of the disease were analyzed. The ARIMA model was constructed and used to predict the incidence trend in 2025. Results From 2012 to 2024, a total of 254 028 HFMD cases were reported in Shanxi Province, with an average annual incidence rate of 54.17 per 100 000 population, a severe case rate of 0.56%, and a case fatality rate (CFR) of 12.60 per 100 000 population. Joinpoint regression analysis showed that the incidence rate, severe case rate, mortality rate, and case fatality rate all presented a downward trend. The epidemic exhibited obvious seasonal distribution characteristics, with the peak period from April to November, and two incidence peaks in June-July and October-November. The male-to-female incidence ratio was 1.41:1. Children aged 1-5 years accounted for 89.24% of the total cases, among which scattered children (58.48%) and nursery children (33.54%) were the high-risk groups. Linfen City (96.06 /100 000) and Taiyuan City (88.54 /100 000) had relatively high incidence rates. After 2017, the proportion of enterovirus A71 (EV-A71) decreased, while coxsackievirus A16 (Cox-A16) and other enteroviruses became the main epidemic strains. The ARIMA(1,0,1)(0,1,1)₁₂ model predicted that the incidence of HFMD in 2025 would remain at the level of 2023-2024, and the dual-peak characteristic would continue. Conclusion From 2012 to 2024, the overall HFMD epidemic in Shanxi Province generally shows a significant downward trend. The high-risk population includes scattered children and nursery children under 5 years old, with high-incidence areas concentrated in the central and southern regions, requiring focused attention. The seasonal ARIMA model can effectively fit the evolutionary trend of HFMD incidence in Shanxi Province and possesses short-term predictive capability.

Objective To investigate the effect of pneumoperitoneum pressure during robotic-assisted kidney transplantation (RAKT) on the function of the transplant kidney. Methods The data of 243 kidney transplant recipients were retrospectively analyzed and divided into open kidney transplantation (OKT) group (n=105) and RAKT group (n=138). The RAKT group was further divided into 13 mmHg group (n=67) and 7 mmHg group (n=71) based on pneumoperitoneum pressure. The donor information, recipient's preoperative general data, intraoperative data, and postoperative recovery of the three groups were compared. In the RAKT group, the renal artery, segmental artery, interlobar artery, and venous flow velocity of the transplant kidney were measured using laparoscopic ultrasound. Results There was a statistically significant difference in donor types among the groups (P<0.05), while other donor information and recipient's preoperative general data showed no statistically significant differences (all P>0.05). There were no statistically significant differences in serum creatinine and complications at 30 days and 1 year postoperatively among the groups (all P>0.05). The OKT group and 7 mmHg group had more intraoperative urine output than the 13 mmHg group. Both RAKT groups had less intraoperative blood loss and shorter hospital stays than the OKT group, and longer operation times than the OKT group (all P<0.05). There were no statistically significant differences in operation time, intraoperative blood loss, and hospital stay between the two RAKT groups (all P>0.05). The vascular flow velocity of the transplant kidney decreased at 13 mmHg compared to 7 mmHg pneumoperitoneum pressure, but the differences were not statistically significant (all P>0.05). Conclusions Controllable pneumoperitoneum pressure has a limited impact on the vascular flow velocity of the transplanted kidney. RAKT is a safe and effective surgical method under appropriate pneumoperitoneum pressure, and choosing a lower pneumoperitoneum pressure is more conducive to the early recovery of renal function postoperatively.

Muscle-invasive bladder cancer (MIBC) is an aggressive cancer with a high recurrence risk due to micrometastases. Standard treatment, neoadjuvant cisplatin-based chemotherapy followed by radical cystectomy, is not suitable for all patients, with many being ineligible or experiencing recurrence, alongside significant toxicity concerns.Current Concepts: The introduction of immune checkpoint inhibitors (ICIs) into the perioperative setting —including neoadjuvant ICI use in cisplatin-ineligible patients, adjuvant ICI use in high-risk individuals, and chemoimmunotherapy in either the preoperative or postoperative period—has demonstrated promising clinical outcomes. Additionally, bladder preservation strategies are currently under investigation in select patients who exhibit favorable treatment responses, aiming to maintain quality of life without compromising oncologic outcomes. Nevertheless, challenges such as overtreatment, long-term toxicity, and immune-related adverse events remain significant, underscoring the necessity for precise patient selection.Discussion and Conclusion: To personalize perioperative management of MIBC, it is essential to develop and clinically implement robust predictive biomarkers. Assessment of molecular residual disease using circulating tumor DNA is emerging as a promising method to stratify risk, guide adjuvant treatment decisions, and monitor therapeutic response in real time. Future research should prioritize the validation of these biomarkers, refinement of patient selection criteria for bladder preservation strategies, and evaluation of novel therapeutic agents such as antibody-drug conjugates and fibroblast growth factor receptor inhibitors in the perioperative setting. Ultimately, adopting a precision oncology approach will be critical for balancing oncologic efficacy with toxicity management and achieving patient-centered outcomes.

This study aims to explore the effects and potential mechanisms of Modified Shuyu Pills in ameliorating depressive behaviors in the mouse model of vascular dementia(VaD). Seventy-two three-month-old male C57BL/6 mice were assigned into six groups: sham, model, low-, medium-, and high-dose Modified Shuyu Pills, and fluoxetine. The other five groups except the sham group underwent bilateral common carotid artery stenosis combined with chronic unpredictable stress. Depressive behaviors were assessed by the sucrose preference test and tail suspension test. Cerebral blood flow was measured by laser speckle imaging. Protein levels of low density lipoprotein receptor(LDLR), mitogen-activated protein kinase kinase(MEK), phosphorylated(p)-MEK, extracellular signal-regulated kinase(ERK), and p-ERK in the ventral tegmental area(VTA) and nucleus accumbens(NAc) were determined by Western blot. The fluorescence intensity of myelin basic protein(MBP) in the VTA and NAc were measured by immunofluorescence. Myelin sheath morphology in the VTA and NAc was observed by luxol fast blue staining, and the ultrastructure of myelin sheath in the VTA and NAc was examined by transmission electron microscopy. In the tail suspension test, the immobility time of the model group was longer than that of the sham group(P<0.01). In the sucrose preference test, the sucrose preference rate of the model group was lower than that of the sham group(P<0.01). After intervention with Modified Shuyu Pills, the immobility time in the tail suspension test was shortened(P<0.01), and the sucrose preference rate increased(P<0.01). Laser speckle imaging results showed that compared with the sham group, the model group showed reduced cerebral blood flow(P<0.01), and the reduction was reversed by medium-and high-dose Modified Shuyu Pills(P<0.01). Western blot results indicated that the relative expression levels of LDLR, p-MEK/MEK, and p-ERK/ERK in the VTA and NAc of the model group were lower than those in the sham group(P<0.01). Medium-and high-dose Modified Shuyu Pills reversed this trend(P<0.01). Immunofluorescence results showed that the fluorescence intensity of MBP in the VTA and NAc of the model group was lower than that of the sham group(P<0.01). The medium-and high-dose Modified Shuyu Pills groups showed increased fluorescence intensity of MBP in the VTA compared with the model group(P<0.01). In the NAc, the fluorescence intensity of MBP in all the groups of Modified Shuyu Pills increased to varying degrees compared with that in the model group(P<0.01). Luxol fast blue staining results showed that the model group presented lighter staining intensity and looser arrangement of myelin fibers than the sham group, indicating significant demyelination in the model group. However, after intervention with medium-and high-dose Modified Shuyu Pills, the staining intensity and myelin sheath structure in the VTA and NAc were improved. Transmission electron microscopy results revealed that the myelin sheath in the VTA and NAc of the sham group was intact and dense, while the model group exhibited extensive myelin loss, with myelin sheath degeneration and disintegration. After intervention with Modified Shuyu Pills, the myelin sheath loss in the VTA and NAc of mice was reduced, and the proportion of myelinated tissue increased. In summary, Modified Shuyu Pills may promote myelination via the VTA-NAc circuit by upregulating the LDLR/MEK/ERK signaling pathway, thereby ameliorating depressive-like behaviors in VaD mice.

OBJECTIVE: To evaluate the effect of biodegradable magnesium alloy materials in promoting tendon-bone healing during rotator cuff tear repair and to investigate their potential underlying biological mechanisms. METHODS: Forty-eight 8-week-old Sprague Dawley rats were taken and randomly divided into groups A, B, and C. Rotator cuff tear models were created and repaired using magnesium alloy sutures in group A and Vicryl Plus 4-0 absorbable sutures in group B, while only subcutaneous incisions and sutures were performed in group C. Organ samples of groups A and B were taken for HE staining at 1 and 2 weeks after operation to evaluate the safety of magnesium alloy, and specimens from the supraspinatus tendon and proximal humerus were harvested at 2, 4, 8, and 12 weeks after operation. The specimens were observed macroscopically at 4 and 12 weeks after operation. Biomechanical tests were performed at 4, 8, and 12 weeks to test the ultimate load and stiffness of the healing sites in groups A and B. At 2, 4, and 12 weeks, the specimens were subjected to the following tests: Micro-CT to evaluate the formation of bone tunnels in groups A and B, HE staining and Masson staining to observe the regeneration of fibrocartilage at the tendon-bone interface after decalcification and sectioning, and Goldner trichrome staining to evaluate the calcification. Immunohistochemical staining was performed to detect the expressions of angiogenic factors, including vascular endothelial growth factor (VEGF) and bone morphogenetic protein 2 (BMP-2), as well as osteogenic factors at the tendon-bone interface. Additionally, immunofluorescence staining was used to examine the expressions of Arginase 1 and Integrin beta-2 to assess M1 and M2 macrophage polarization at the tendon-bone interface. The role of the phosphatidylinositol 3-kinase (PI3K)/protein kinase B (AKT) signaling pathway in tendon-bone healing was further analyzed using real-time fluorescence quantitative PCR. RESULTS: Analysis of visceral sections revealed that magnesium ions released during the degradation of magnesium alloys did not cause significant toxic effects on organs such as the heart, liver, spleen, lungs, and kidneys, indicating good biosafety. Histological analysis further demonstrated that fibrocartilage regeneration at the tendon-bone interface in group A occurred earlier, and the amount of fibrocartilage was significantly greater compared to group B, suggesting a positive effect of magnesium alloy material on tendon-bone interface repair. Additionally, Micro-CT analysis results revealed that bone tunnel formation occurred more rapidly in group A compared to group B, further supporting the beneficial effect of magnesium alloy on bone healing. Biomechanical testing showed that the ultimate load in group A was consistently higher than in group B, and the stiffness of group A was also greater than that of group B at 4 weeks, indicating stronger tissue-carrying capacity following tendon-bone interface repair and highlighting the potential of magnesium alloy in enhancing tendon-bone healing. Immunohistochemical staining results indicated that the expressions of VEGF and BMP-2 were significantly upregulated during the early stages of healing, suggesting that magnesium alloy effectively promoted angiogenesis and bone formation, thereby accelerating the tendon-bone healing process. Immunofluorescence staining further revealed that magnesium ions exerted significant anti-inflammatory effects by regulating macrophage polarization, promoting their shift toward the M2 phenotype. Real-time fluorescence quantitative PCR results demonstrated that magnesium ions could facilitate tendon-bone healing by modulating the PI3K/AKT signaling pathway. CONCLUSION Biodegradable magnesium alloy material accelerated fibrocartilage regeneration and calcification at the tendon-bone interface in rat rotator cuff tear repair by regulating the PI3K/AKT signaling pathway, thereby significantly enhancing tendon-bone healing.

OBJECTIVE: To evaluate the clinical efficacy of modified high tibial osteotomy combined with platelet-rich plasma in the treatment of moderate to severe knee osteoarthritis. METHODS: From January 2021 to March 2022, the clinical data of 60 patients with moderate to severe knee osteoarthritis admitted to the Third Affiliated Hospital of Beijing University of Chinese Medicine were analyzed. Among them, 30 patients were treated with modified tibia high osteotomy combined with platelet-rich plasma as the observation group, including 12 males and 18 females, aged from 51 to 74 years old, with an average age of (64.37±5.72) years old. The course of disease ranged from 1 to 7 years with an average of(3.43±1.41) years. Thirty patients were treated with modified high tibial osteotomy combined with sodium hyaluronate as control group, including 10 males and 20 females, aged from 50 to 78 years, with an average age of (64.33±8.18) years. The course of disease was 1 to 7 years with an average of(3.30±1.39) years. Knee X-rays were taken before surgery and at the last follow-up, and the changes of lower limb bearing-line ratio (WBLR), proximal medial tibial Angle (MPTA), femoro-tibial angle (FTA) and posterior tibial slope (PTS) were compared between the two times. Visual analogue scale (VAS), Western Ontario and McMaster University Osteoarthritis Index (WOMAC) and Lysholm score were used to evaluate knee pain and functional changes before surgery and at 1, 3, and 6 months after surgery. RESULTS: The wounds of all patients healed in stage I after surgery. All 60 patients completed treatment and follow-up, with an average follow-up duration of (8.08±1.75) months, ranged from 6 to 12 months. No serious adverse events or complications occurred. At the last follow-up, WBLR, MPTA and FTA were significantly improved in both groups (P<0.05). At the last follow-up, there was no significant difference in PTS between the two groups compared with pre-operation(P>0.05). At the last follow-up, there were no significant differences in WBLR, MPTA, FTA and PTS between the observation group and the control group (P>0.05). The VAS scores, WOMAC scores and Lysholm scores of both groups were significantly Modified with time after operation (P<0.05). At 1, 3 and 6 months after operation, VAS score, WOMAC score and Lysholm score of the observation group were significantly better than those of the control group, with statistical significance (P<0.05). CONCLUSION For patients with moderate and severe knee osteoarthritis, modified high tibial osteotomy can significantly correct lower limb alignment, and combined with platelet-rich plasma therapy can further significantly relieve knee pain and improve knee function, the effect is better than combined with sodium hyaluronate.

OBJECTIVE: To compare clinical efficacy of tibial transverse transport (TTT) microcirculation reconstruction and periosteal distraction in treating patients with early diabetic foot(DF). METHODS: From June 2021 to June 2024, 60 patients with DF were admitted and divided into bone transport group and stretch group according to different treatment methods. There were 30 patients in bone transport group, including 16 males and 14 females;aged from 48 to 65 years old with an average of (55.59±3.78) years old;the course of disease ranged from 2 to 9 months with an average of(5.95±1.32) months;TTT microcirculation reconstruction surgery was performed. There were 30 patients in distraction group, including 17 males and 13 females;aged from 47 to 67 years old with an average of (55.24±3.81) years old;the course of disease ranged from 2 to 10 months with an average of (5.68±1.54) months;periosteal distraction surgery was performed. The skin temperature of the affected feet, the time of getting out of bed and walking after operation, the time of full weight-bearing, the wound healing time and complications were compared between two groups;the pain was evaluated by visual analogue scale (VAS) before operation and one month after operation respectively;the changes of blood flow velocity of dorsal foot arteries, ankle brachial index(ABI), epidermal growth factor (EGF), and basic fibroblast growth factor (bFGF) before and after operation at 3 months were compared between two groups. RESULTS: All patients were followed up for 3 to 4 months with an average of (3.52±0.12) months. There were no statistically significant differences in comparison of foot skin temperature, postoperative walking time, full weight-bearing time and complications between two groups (P>0.05). The wound healing time of bone transport group (61.26±7.31) days was shorter than that of distraction group (70.17±7.15) days, and the difference was statistically significant (P<0.05). Postoperative VAS at 1 month of bone transport group (2.19±0.21) was lower than that of distraction group (2.55±0.20), and the difference was statistically significant (P<0.05). At 3 months after operation, the blood flow velocity of dorsal foot artery, ankle-brachial index, EGF and bFGF in bone transport group were(34.73±4.18) cm·s^-1, (0.95±0.13), (716.61±71.13) pg·ml^-1 and (175.69±31.28) pg·ml^-1, respectively;which were higher than that of distraction group (31.86±3.23) cm·s^-1, (0.84±0.11), (677.37±70.21) pg·ml^-1, (149.26±30.13) pg·ml^-1, and the differences were statistically significant (P<0.05). There was no recurrence of ulcers in situ or at other sites in both groups during follow-up. CONCLUSION Compared with periosteal distraction, TTT microcirculation reconstruction surgery has a definite effect in the treatment of early DF. It could effectively reduce pain level, improve blood flow indicators and vascular endothelial function of the foot, and has a relatively high safety.
