To ensure the quality of care for inpatients in ophthalmic hospitals, address the complex and variable conditions of postoperative patients, and conduct more comprehensive, accurate and real-time monitoring of patients, an intelligent monitoring system based on computer vision and artificial intelligence has been designed. This system is employed for real-time monitoring of patient health conditions and intelligent care, with primary applications in medical monitoring, rehabilitation therapy, and inpatient care. It comprises intelligent data acquisition devices, smart cameras, continuous physiological data analysis algorithms, AI algorithms, and software. Given the complex and variable conditions of postoperative patients in ophthalmic hospitals, a comprehensive, accurate, and real-time monitoring of patients is required. Therefore, it is necessary to explore a monitoring technology that imposes low physiological and psychological burdens. The intelligent monitoring system can continuously collect patients' physiological parameter indicators and transmit the monitoring data to doctors' workstations or nurse stations after analysis using intelligent algorithms, providing new tools for patient monitoring, disease assessment, risk warning, and more. Furthermore, through the application of computer vision and artificial intelligence technologies, the system can analyze facial expressions, body postures, and other data to identify patients' emotional states and bedridden postures, enabling the timely detection of abnormal situations and implementation corresponding measures. This helps improving the daily work of medical staff, enhance the nursing safety in single-patient rooms in wards, and potentially find applications in the care of critically ill patients and elderly patients, thereby improving nursing efficiency and quality.

Increasing evidence shows that the early lesions of Parkinson's disease (PD) originate from gut, and correction of microbiota dysbiosis is a promising therapy for PD. FLZ is a neuroprotective agent on PD, which has been validated capable of alleviating microbiota dysbiosis in PD mice. However, the detailed mechanisms still need elucidated. Through metabolomics and 16S rRNA analysis, we identified glycoursodeoxycholic acid (GUDCA) was the most affected differential microbial metabolite by FLZ treatment, which was specially and negatively regulated by Clostridium innocuum, a differential microbiota with the strongest correlation to GUDCA production, through inhibiting bile salt hydrolase (BSH) enzyme. The protection of GUDCA on colon and brain were also clarified in PD models, showing that it could activate Nrf2 pathway, further validating that FLZ protected dopaminergic neurons through promoting GUDCA production. Our study uncovered that FLZ improved PD through microbiota-gut-brain axis, and also gave insights into modulation of microbial metabolites may serve as an important strategy for treating PD.

Although enteric glial cell (EGC) abnormal activation is reported to be involved in the pathogenesis of Parkinson's disease (PD), and inhibition of EGC gliosis alleviated gut and dopaminergic neuronal dysfunction was verified in our previous study, the potential role of gut microbiota on EGC function in PD still need to be addressed. In the present study, fecal microbiota transplantation revealed that EGC function was regulated by gut microbiota. By employing 16S rRNA and metabolomic analysis, we identified that 3-indolepropionic acid (IPA) was the most affected differential microbial metabolite that regulated EGC gliosis. The protective effects of IPA on PD were validated in rotenone-stimulated EGCs and rotenone (30 mg/kg i.g. for 4 weeks)-induced PD mice, as indicated by decreased inflammation, improved intestinal and brain barrier as well as dopaminergic neuronal function. Mechanistic study showed that IPA targeted pregnane X receptor (PXR) in EGCs, and inhibition of IL-13Rα1 involved cytokine-cytokine receptor interaction pathway, leading to inactivation of downstream JAK1-STAT6 pathway. Our data not only provided evidence that EGC gliosis was critical in spreading intestinal damage to brain, but also highlighted the potential role of microbial metabolite IPA in alleviating PD pathological damages through gut-brain axis.

OBJECTIVES: To investigate the effects of dihydroartemisinin (DHA) combined with doxorubicin (DOX) on proliferation and apoptosis of triple-negative breast cancer cells and explore the underlying molecular mechanism. METHODS: MDA-MB-231 cells were treated with 50, 100 or 150 μmol/L DHA, 0.5 μmol/L DOX, or with 50 μmol/L DHA combined with 0.5 μmol/L DOX. The changes in proliferation and survival of the treated cells were examined with MTT assay and colony-forming assay, and cell apoptosis was analyzed with flow cytometry. Western blotting was performed to detect the changes in protein expression levels of PCNA, cleaved PARP, Bcl-2, Bax, STAT3, p-STAT3, HIF-1α and survivin. RESULTS: The IC₅₀ of DHA was 131.37±29.87 μmol/L in MDA-MB-231 cells. The cells with the combined treatment with DHA and DOX showed significant suppression of cell proliferation. Treatment with DHA alone induced apoptosis of MDA-MB-231 cells in a dose-dependent manner, but the combined treatment produced a much stronger apoptosis-inducing effect than both DHA and DOX alone. DHA at 150 μmol/L significantly inhibited clone formation of MDA-MB-231 cells, markedly reduced cellular expression levels of PCNA, p-STAT3, HIF-1α and survivin proteins, and obviously increased the expression level of cleaved PARP protein and the Bax/Bcl-2 ratio, and the combined treatment further reduced the expression level of p-STAT3 protein and increased the Bax/Bcl-2 ratio. CONCLUSIONS DHA combined with DOX produces significantly enhanced effects for inhibiting cell proliferation and inducing apoptosis in MDA-MB-231 cells possibly as result of DHA-mediated negative regulation of the STAT3/HIF-1α pathway.

Objective To investigate the clinical efficacy of the Lower Limb Detumescence Formula(derived from Taohong Siwu Decoction)in treating lower limb swelling in patients with qi stagnation and blood stasis syndrome after total knee arthroplasty(TKA),and to analyze the changes in traditional Chinese medicine(TCM)syndrome types before and after surgery.Methods A total of 60 patients diagnosed with knee osteoarthritis and lower limb swelling with qi stagnation and blood stasis syndrome after TKA,hospitalized in the Department of Artificial Joints and Knee Surgery,The First Affiliated Hospital of Guangzhou University of Chinese Medicine between November 2024 and January 2025,were selected.Based on patients' preferences and postoperative medication,the patients were divided into three groups:the Chinese medicine Group(25 cases),the Lishang Group(15 cases),and the Aescuven Forte Group(20 cases).Changes in limb circumference on the affected side were used to describe knee volume changes,and were measured preoperatively and on postoperative days 1,3,and 30.Results(1)Regarding lower limb swelling,the calf and thigh circumferences of the affected side in all three groups showed a trend of early exacerbation(on postoperative days 1 and 3)followed by later relief(on postoperative day 30).Peak swelling occurred on postoperative day 3,with statistically significant differences compared to preoperative measurements(P＜0.05).Subsequently,swelling gradually alleviated,and the calf and thigh circumferences of the affected side progressively decreased,the circum ferences on postoperative day 30 differed from those on postoperative days 1 and 3(P＜0.05).However,there were no statistically significant differences in improving calf and thigh circumferences among the three groups(P＞0.05).(2)In terms of adverse reactions,the Lishang Group and the Aescuven Forte Group each reported two adverse events,including postoperative wound bleeding,subcutaneous ecchymosis,pulmonary infection,and constipation.The Chinese medicine group reported no gastrointestinal adverse events,and patient treatment compliance was better than that in the Lishang Group and the Aescuven Forte Group.(3)Regarding TCM syndrome differentiation,each patient received four assessments at different time points(preoperatively and on postoperative days 1,3,and 30),resulting in 240 valid data entries.Among these,qi stagnation and blood stasis syndrome was the most common(170 cases,70.83％),followed by liver and kidney deficiency syndrome(64 cases,26.67％),and qi and blood deficiency syndrome was the least common(6 cases,2.50％).(4)Comparison of the relationship between different groups and syndrome types revealed no significant association between group distribution and syndrome type(P＞0.05).Further generalized estimating equation analysis showed that grouping had no significant effect on TCM syndrome differentiation(P＞0.05).(5)Comparison of the relationship between different time points and syndrome types revealed that preoperative syndromes predominantly consisted of liver and kidney deficiency(96.67％),while on postoperative days 1 and 3,all cases were classified as qi stagnation and blood stasis syndrome(100.00％).On postoperative day 30,qi stagnation and blood stasis syndrome remained the most common(80.00％).There was a significant association between time points and syndrome distribution(P＜0.05).Further generalized estimating equation analysis indicated that time points significantly influenced TCM syndrome differentiation(P＜0.001).Conclusion The Lower Limb Detumescence Formula demonstrates efficacy comparable to Lishang Xiaozhong Oral Liquid and Aescuven Forte Tablets in improving lower limb swelling in patients with qi stagnation and blood stasis syndrome after TKA.By promoting blood circulation,resolving stasis,strengthening the spleen,and eliminating accumulation,this formula reduces the incidence of adverse reactions such as postoperative wound bleeding,subcutaneous ecchymosis,and constipation.It provides a new pharmacological option for treating lower limb swelling after TKA,and is particularly suitable for patients with qi stagnation and blood stasis syndrome accompanied by spleen deficiency.

BACKGROUND:Medial open wedge high tibial osteotomy is an effective procedure for preserving the knee joint in patients with medial compartmental osteoarthritis.Previous studies have demonstrated that the forgotten joint score provides a lower ceiling effect and consistency of medial open wedge high tibial osteotomy outcomes compared to traditional assessment tools. OBJECTIVE:To identify predictive factors associated with the occurrence of a forgotten joint after medial open wedge high tibial osteotomy. METHODS:117 patients with medial open wedge high tibial osteotomy who were treated at First Affiliated Hospital of Guangzhou University of Chinese Medicine were selected,including 35 males and 82 females,with an average age of 61 years.They were followed up for at least 2 years.Patients were divided into a forgotten joint group(n=28)and a non-forgotten joint group(n=89)by evaluating whether they achieved forgotten joint after surgery.Univariate and multivariate logistic regression analyses were performed with preoperative patient characteristics and surgery-related factors as potential predictors. RESULTS AND CONCLUSION:(1)There were significant differences in the proximal medial tibial angle between the two groups before surgery(P<0.05).There were significant differences in the forgotten joint score,Knee Injury and Osteoarthritis Outcome Score,knee society knee score,function score,and patients joint perception between the two groups after surgery(P<0.05).There was a significant difference between the hip-knee-ankle angle and the medial proximal tibial angle after operation(P<0.05).(2)Univariate Logistic regression analysis showed that the medial proximal tibial angle had a significant influence on the forgotten joint before operation[OR=0.755,95%CI(0.635-0.897),P<0.001].There were significant effects on the forgotten joint of hip-knee-ankle angle and medial proximal tibial angle[OR=1.546,95%CI(1.242-1.924),P<0.001;OR=0.815,95%CI(0.713-0.931),P=0.003].(3)Multivariate logistic regression analysis showed that preoperative K-L grade 1 was a favorable factor for obtaining forgotten joints.Preoperative medial proximal tibial angle and postoperative hip-knee-ankle angle were independent predictors of forgetting joints,and they had a curvilinear relationship with the probability of achieving forgetting joints.When preoperative medial proximal tibial angle increased by 1°,the probability of achieving a forgotten joint decreased by 27.7%[OR=0.723,95%CI(0.593-0.882),P<0.001].Conversely,when postoperative hip-knee-ankle angle increased by 1°,the probability of achieving a forgotten joint increased by 46.4%[OR=1.464,95%CI(1.153-1.860),P=0.002].(4)The results showed that patients with preoperative knee osteoarthritis K-L grade 1,small medial proximal tibial angle(<85.5°),and large postoperative hip-knee-ankle angle(>176.0°)were predictors of forgotten joint.

Objective:To explore the force distribution on the maxillary dentition when the first and second molars distalized simultaneously with different step sizes using clear aligners in vitro in order to provide a theoretical basis for the rational design of molar distalization. Methods:Clear aligners were designed to simultaneously distalize the maxillary first and second molars bilaterally, with rectangular attachments placed on the buccal surfaces of the first and second premolars, as well as the second molars. Based on different step sizes, the aligners were divided into three groups: Group A (0.15 mm per step), Group B (0.20 mm per step), and Group C (0.25 mm per step). Ten aligners were fabricated for each group using 0.76 mm thick polyethylene terephthalate glycol (PET-G) sheets. A three-dimensional force measurement system was used to measure the forces exerted on each tooth by the aligners, the first and second molars served as the target teeth and the remaining teeth as anchorage teeth. The three-dimensional force data were compared among the three groups.Results:In the mesiodistal direction, the forces on the central and lateral incisors were relatively small among all three groups, with no statistically significant differences ( P>0.05). However, significant differences were observed in the forces on the canines, first premolars, second premolars, first molars, and second molars ( P<0.05). The distal forces on the second molars in Groups B and C were (6.13±1.45) N and (6.83±1.58) N, respectively, significantly higher than that in Group A [(3.51±1.01) N] ( P<0.05). The distal force on the first molars in Group C [(6.62±0.89) N] was significantly higher than that in Groups A and B ( P<0.05). The mesial reactive forces on the first and second premolars in Groups B and C were significantly higher than those in Group A ( P<0.05). The mesial reactive force on the canines in Group C [(-2.98±1.33) N] was significantly higher than that in Group A [(-1.69±0.68) N] ( P<0.05), while there were no significant differences between Groups B and C in the forces on the canines, first premolars, and second premolars ( P>0.05). In the buccolingual direction, there were no statistically significant differences in the forces on the central and lateral incisors among three groups ( P>0.05), but significant differences were observed in the forces on the canines, second premolars, and second molars ( P<0.05). The buccolingual forces on the canines, second premolars, and second molars in Group B were (-0.56±0.54), (-2.07±0.95), (1.13±0.55) N, respectively, significantly higher than those in Group A ( P<0.05), but there were no significant differences compared to Group C ( P>0.05). Compared to the mesiodistal and buccolingual forces, the vertical forces on the target and anchorage teeth were relatively small in all three groups. Conclusions:When using 0.76 mm thick PET-G sheets to fabricate clear aligners for simultaneous molar distalization, a step size of 0.20 mm per step is recommended. To prevent buccal tipping of the molars during distalization, it is advisable to design lingual displacement for the molars and buccal displacement for the adjacent anchorage teeth to counteract the unfavorable forces, with attachments placed on the primary anchorage teeth.

Objective: To prepare an inactivated hepatitis A vaccine using a attenuated strain of hepatitis A virus (HAV) H2 and to analyze its immunizing dose, so as to provide the reference for development and production of inactivated hepatitis A vaccines. Methods: Human embryonic lung diploid cells (KMB17) were infected with attenuated HAV H2 strain to proliferate the virus, then the cells containing viruses were harvested, extracted and purified. The obtained virus concentrate was prepared into vaccine bulk and test vaccines with 1 280 EU/mL antigen content. Vaccine testing was carried out according to the inactivated hepatitis A vaccine standards specified in the Part Ⅲ of the Pharmacopoeia of the People's Republic of China (2020 edition). A total of 110 mice were randomly divided into 11 groups, including 5 dose groups (80, 160, 320, 640 and 1 280 EU/dose) of the test vaccine and the reference vaccine, as well as the adjuvant control group. Mice were immunized twice by intraperitoneal injection, their serum HAV antibodies were detected, and the geometric mean titer (GMT) and positive conversion rate of antibodies were analyzed to evaluate the immunising dose of the vaccine. Results: The antigen content and viral titer of the virus harvest solution were 5 120 EU/mL and 8.33 lgCCID50/mL, respectively. The removal rate of foreign protein reached 98.05% and the recovery rate of antigen was 66.25%. The test vaccine met the requirements of Part Ⅲ of the Pharmacopoeia of the People's Republic of China (2020 edition). The GMTs of HAV antibodies in the test vaccine and the reference vaccine dose groups after the second immunization were more than twice higher than those after the first immunization. Regardless of primary immunization or secondary immunization, the GMTs (log2) of HAV antibodies in the test vaccine groups with doses of 160 EU/dose and above were higher than those in the 80 EU/dose group (all P<0.05), while there was no statistically significant differences between the dose groups of 160 EU/dose and above (all P>0.05). The antibody positive conversion rate of 160 EU/dose and above of the test vaccine was 100.00% after the secondary immunization. Conclusions The inactivated hepatitis A vaccine of attenuated H2 strain tested in this study demonstrates strong immunogenicity in mice, suggesting its potential as a candidate vaccine. The preliminary analysis indicates an immunizing dose of 320 EU/dose for children and 640 EU/dose for adults.
