ObjectiveTo investigate whether Danggui Shaoyaosan (DSS) inhibits oxidative stress and alleviates inflammation via the Ras homolog family member A (RhoA)/Rho-associated coiled-coil containing protein kinase 1 (ROCK)/nuclear factor kappa-B (NF-κB) signaling pathway, thereby delaying the progression of diabetic kidney disease (DKD) and exerting a nephroprotective effect. MethodsEight db/m mice were assigned to the normal group, and forty 8-week-old db/db mice were randomly divided into the model group, DSS low-dose group (8.39 g·kg-1), DSS medium-dose group (16.77 g·kg-1), DSS high-dose group (33.54 g·kg-1), and irbesartan group (0.025 g·kg-1), with eight mice in each group. All groups were administered the corresponding treatment by gavage once daily for 12 weeks. The normal and model groups received an equal volume of saline. During administration, changes in body weight, fasting blood glucose (FBG), and 24 hour urinary protein (24 h UTP) were observed. After 12 consecutive weeks of administration, hematoxylin-eosin (HE) staining and Masson's trichrome staining were used to observe renal histopathological changes in each group. The levels of reactive oxygen species (ROS) in renal tissue were detected using the dihydroethidium (DHE) method. The expression levels of superoxide dismutase (SOD) and malondialdehyde (MDA) in renal tissue were determined. Serum interleukin-1β (IL-1β) and interleukin-6 (IL-6) levels were measured using enzyme-linked immunosorbent assay (ELISA). The mRNA expression levels of RhoA, ROCK1, and NF-κB p65 in renal tissues were detected by Real-time quantitative polymerase chain reaction (Real-time PCR). Protein expression levels of fibronectin (FN), Collagen Ⅳ(Col Ⅳ), transforming growth factor-β1 (TGF-β1), RhoA, ROCK, and NF-κB p65 in renal tissues were determined by Western blot. ResultsCompared with the normal group, the model group showed significantly increased body weight, FBG, and 24 h UTP levels (P<0.01), elevated serum IL-1β and IL-6 levels, enlarged glomerular volume, diffuse mesangial expansion, increased mesangial matrix, and marked collagen fiber proliferation in renal tissues. SOD activity was decreased, while MDA, ROS, RhoA, ROCK1, and NF-κB p65 mRNA expression levels were increased (P<0.01), and the protein expression levels of FN, Col Ⅳ, TGF-β1, RhoA, ROCK, and NF-κB p65 were also elevated (P<0.01). Compared with the model group, the DSS low-, medium-, and high-dose groups and the irbesartan group showed reductions in body weight, FBG, and 24 h UTP, decreased serum IL-1β and IL-6 levels, varying degrees of improvement in renal histopathology, increased SOD activity, decreased MDA levels, reduced ROS expression, and significantly downregulated RhoA, ROCK1, and NF-κB p65 mRNA expression (P<0.05, P<0.01), as well as reduced protein expression levels of FN, Col Ⅳ, TGF-β1, RhoA, ROCK, and NF-κB p65 (P<0.05, P<0.01). ConclusionDSS can alleviate oxidative stress and inflammation, reduce extracellular matrix deposition, and delay renal fibrosis progression in db/db mice. Its mechanism may be related to the inhibition of the RhoA/ROCK/NF-κB signaling pathway, thereby exerting a therapeutic effect on DKD.

The paper summarizes Professor YANG Jun's experience in treatment of refractory facial paralysis with the refined mode of acupuncture and moxibustion, so as to provide new ideas and methods for the disease treated with acupuncture and moxibustion. Professor YANG Jun puts forward the refined mode of diagnosis and treatment of acupuncture and moxibustion for refractory facial paralysis. On the basis of syndrome/pattern differentiation of TCM, combined with meridian theory and modern anatomy, the symptom differentiation and meridian differentiation are performed accurately. By selecting local acupoints (e.g. Touwei [ST8], Sibai [ST2], Cuanzhu [BL2] and Yangbai [GB14]), distal acupoints (e.g. Zusanli [ST36], Hegu [LI4] and Jinsuo [GV8]), specific acupoints (e.g.Qianzheng [EX-HN16] and Touqiaoyin [GB11]) and the acupoints for regulating the mind (e.g. Dazhui [GV14] and Shuigou [GV26]), the prescription is composed. The different needling techniques are delivered at the acupoints (e.g. point-to-point needling with long needle, stuck needling by lifting and dragging, and balance needling on the healthy side). Besides, the facial rehabilitation is considered as the adjuvant treatment. This mode of treatment obtains the precise diagnosis and treatment to achieve the utmost therapeutic effects.

OBJECTIVES:
This study aims to investigate factors influencing dental arch development in patients aged 0-6 years with cleft palate after Sommerlad-Furlow (SF) palatoplasty.
METHODS:
A total of 183 patients who underwent primary SF repair for cleft lip and palate before 18 months of age were included. Follow-ups were conducted at different ages, and digital dental casts of the maxillary dental arch were obtained using 3-matic Research 12.0 software. The length and width of the dental arch and palate were measured to explore developmental changes in the maxillary dental arch of the patients after the procedure. The study also investigated the influence of gender, age, cleft palate type, and relaxation incision on maxillary dental arch development.
RESULTS:
After SF, maxillary dental arch measurements showed statistically significant differences between children aged 0-2 years and those aged 3-6 years (P<0.05). However, no statistically significant differences were observed among different age groups within the 3-6 years range. Statistically significant differences were detected between males and females, with males having greater width of the posterior dental arch and palate (P=0.001) and shorter length of the anterior dental arch and entire dental arch (P<0.05). The unilateral cleft lip and palate group had shorter dental arch length (P<0.01) and wider posterior palate (P<0.01) than the cleft palate only group. Maxillary dental arch measurements had no statistically significant differences between groups with or without a relaxing incision.
CONCLUSIONS
Gender and age influence the width of the maxillary dental arch in children aged 0-6 years after SF, while age and cleft palate type affect dental arch length.

In recent years, the exploration and development of artificial intelligence (AI) technology in clinical trials for liver diseases have promoted the continuous innovation of research methods and processes in this field. AI has gradually become an important technical tool for various links of clinical trial including patient selection, risk stratification, endpoint evaluation, and result interpretation. Nevertheless, the standardized integration of AI into clinical trials still faces the methodological challenges such as data quality control, model interpretability, and causal inference. From the perspective of methodology, this article systematically reviews the principal application scenarios of AI as an object under investigation (validation trials) and as a research tool (supportive trials) in clinical trials for liver diseases, as well as the major methodological challenges of AI-related clinical trials along and the corresponding solution strategies, in order to provide methodological guidance for promoting the scientific and standardized implementation of AI technologies.

Objective To investigate the synergistic therapeutic effects of HER2 antibody-drug conjugate(HER2-ADC)combined with anti-PD-1 antibody(anti-PD-1)on HER2-expressing bladder cancer and elucidate its regulatory mechanisms on the tumor immune microenvironment.Methods Orthotopic tumor models were established in 40 female C57BL/6 mice(6~8 weeks old,body mass 18~22 g)using MB49 bladder cancer cells overexpressing human HER2.When tumors reached 100 mm3,the mice were randomized into(n=10)control(intraperitoneal injection of 1.0 mL PBS),anti-PD-1(200 μg per mouse every 3 d),HER2-ADC(2.5 mg/kg once weekly),and combination groups(same regimens as above monotherapy).Tumor volume and body mass were measured every 3 d during 28-day treatment.Tumor growth kinetics and survival rates were analyzed.Post-treatment survival was monitored until natural death to determine median survival time(n=5).At day 28,blood and tumor samples(n=5)were collected to detect myeloid-derived suppressor cells(MDSCs;CD11b?Gr1?)and regulatory T cells(Tregs;CD4?CD25?FOXP3?)with flow cytometry,tumor-infiltrating CD3?T,CD8?T,and FOXP3?T cells with immunohistochemical assasy,and liver/kidney functions[alanine aminotransferase(ALT),aspartate aminotransferase(AST),blood urea nitrogen(BUN),creatinine(CRE)]and tissue damage indicators[lactate dehydrogenase isoenzyme(LDH-L)].Results In 28 d after treatment,the combination group obtained significantly smallest tumor volume than the control group and the 2 monotherapy groups(all P<0.01).The longest median survival was observed in the combination group(65 d,P<0.01),followed by the HER2-ADC group(55 d),anti-PD-1 group(53 d)and control group(41 d).After 28 d of treatment,the combination group exhibited obviously the smallest peripheral proportions of MDSCs/Tregs,most tumor-infiltrating CD3?T/CD8?T cells,and less FOXP3?T cells when compared with the 2 monotherapy groups and control group(all P<0.05).While,the 2 monotherapy groups had smaller MDSCs/Tregs proportions than the control group(P<0.05).No significant differences were observed among the 4 groups in serum ALT,AST,BUN,CRE,or LDH-L levels,and all of them were within normal ranges.Conclusion HER2-ADC combined with anti-PD-1 suppresses the growth of orthotopic bladder tumor,probably through their synergic effects on down-regulating MDSCs/Treg and enhancing CD8?T cell infiltration.

OBJECTIVE To analyze the peak wideband acoustic immittance(WAI)values reflecting the tympanic membrane absorption characteristics during the measurement process in patients with congenital middle ear malformation.METHODS We selected 36 patients diagnosed with congenital middle ear malformation by CT as subjects and evaluated their tympanic membrane absorption characteristics by measuring their acoustic impedance peak pressure.Then,we divided these data into two groups based on the pathological malformation obseved during the surgical process,namely the auditory ossicular chain soft connection group and the auditory ossicular chain fixation group.Calculate the absorption rate values of the tympanic membrane at each frequency corresponding to the peak pressure value of the tympanogram,and the relative area of absorption rate.By conducting independent t-tests,we compared two groups-normal children and patients who had undergone ossicular chain fixation surgery-to analyze the absorption area and peak absorption rate of their tympanic peak pressure values.RESULTS Under peak pressure,there were significant differences(P<0.001)in the full frequency range tympanic membrane absorption rate and peak absorption rate between the group with fixed ossicular chain and the normal group.However,there was no difference in the full frequency range tympanic membrane absorption rate and peak absorption rate between the group with soft ossicular chain and the normal group.Under peak pressure,the absorption area of the ossicular chain fixation group was significantly lower than that of the normal group in the low frequency range of 226-1 000 Hz(P<0.001),while the absorption area of the ossicular chain soft connection group was significantly higher than that of the normal group in the low frequency range of 226-1 000 Hz(P<0.001).CONCLUSION When conducting broadband acoustic impedance test,there is a significant difference in the relative area of tympanic membrane absorption rate of acoustic impedance peak pressure between the auditory ossicular chain soft connection group and the auditory ossicular chain fixation group across 226-1 000 Hz.It has application value as a clinical rapid screening and diagnostic tool for middle ear malformations.

Childhood primary renal tubular diseases are chronic kidney diseases characterized by impaired renal tubular reabsorption. Primary renal tubular disease has diverse clinical manifestations and lacks of specificity. Laboratory tests are limited,making it prone to missed diagnosis and misdiagnosis. Based on the current knowledge of renal tubular diseases,authors propose early warning signals of renal tubular diseases such as family history of primary tubular diseases,unexplained polyhydramnios during pregnancy,polydipsia,polyuria,delayed growth and development or rickets,decreased muscle strength and tone,unexplained electrolyte disturbance,hyperuricemia,acid-base disturbance,positive urine sugar test,renal tubular proteinuria,urinary imaging examination suggesting kidney stones,calcium deposition,renal cysts and early onset of eye,ear,joint and neuron injury.Meanwhile,some universal management strategies for primary renal tubular disease are proposed,emphasizing the importance of multidisciplinary collaboration,genetic testing and individualized intervention to improve the long-term prognosis of childhood primary renal tubular diseases.

Objective To investigate the correlation between serum homeodomain interacting protein ki-nase 2(HIPK2),annexin A5(ANXA5)and coronary stenosis and prognosis in patients with acute myocardial infarction(AMI).Methods A total of 277 AMI patients who received interventional treatment in this hospi-tal from January 2021 to July 2023 were selected as the AMI group,and another 140 cases with normal or very mild stenosis in coronary angiography during the same period were selected as the control group.According to the degree of coronary artery stenosis(Gensini score),the AMI patients were divided into mild coronary arter-y stenosis group(86 cases),moderate coronary artery disease group(111 cases)and severe coronary artery disease group(80 cases).According to the prognosis,they were divided into poor prognosis group(80 cases)and good prognosis group(197 cases).Enzyme-linked immunosorbent assay was used to detect the serum HIPK2 and ANXA5 levels.Spearman correlation analysis was used to analyze the correlation between serum HIPK2 and ANXA5 levels and Gensini score in patients with AMI.Multivariate unconditional Logistic regres-sion was used to determine the relationship between serum HIPK2 and ANXA5 levels and prognosis of AMI patients.Receiver operating characteristic(ROC)curve was used to analyze the predictive efficiency of serum HIPK2 and ANXA5 levels on prognosis of AMI patients.Results Compared with the control group,the ser-um HIPK2 level in the AMI group increased and the ANXA5 level decreased,and the differences were statisti-cally significant(P<0.05).The serum HIPK2 levels in the mild coronary artery stenosis group,moderate coronary artery stenosis group and severe coronary artery stenosis group increased successively,while the ANXA5 levels decreased successively,and the differences were statistically significant(P<0.05).Gensini score was positively correlated with serum HIPK2 level and negatively correlated with serum ANXA5 level in AMI patients(P<0.05).The Gensini score of AMI patients was positively correlated with the serum HIPK2 level(r=0.785,P<0.05),and negatively correlated with the serum ANXA5 level(r=-0.798,P<0.05).Compared with the good prognosis group,the serum HIPK2 level in the poor prognosis group increased(P<0.05),and the ANXA5 level decreased(P<0.05).After adjusting for confounding factors,high HIPK2 was an independent risk factor for poor prognosis in AMI patients(P<0.05),and high ANXA5 was an independ-ent protective factor(P<0.05).The area under the curve of the combined prediction of serum HIPK2 and ANXA5 levels for the prognosis of AMI patients was 0.875,which was greater than 0.778 and 0.784 predic-ted by serum HIPK2 and ANXA5 levels alone(P<0.05).Conclusion The serum HIPK2 level is increased and the ANXA5 level is decreased in patients with AMI,which is related to the aggravation of coronary steno-sis and the poor prognosis.The combination of serum HIPK2 and ANXA5 levels is more effective in predic-ting the prognosis of patients with AMI.

OBJECTIVE:
To evaluate the effect of palliative care on drug use, medical service utilization and medical expenditure of patients with advanced cancer.
METHODS:
A cohort of patients including pal-liative care and standard care was constructed using the medical records of the patients in Peking University Cancer Hospital from 2018 to 2020, and coarsened exact matching was used to match the two groups of patients. The average monthly opioid consumption, hospitalization rate, intensive care unit (ICU) rate and operation rate, and the average monthly total cost were selected to evaluate drug use, medical service utilization and medical expenditure. Chi-square test and Wilcoxon signed rank test were used to compare the differences between the two groups before and after exposure and the change in the palliative care group. The net impact of palliative care on the patients was calculated using the difference-in-differences analysis.
RESULTS:
In this study, 180 patients in the palliative care group and 3 101 patients in the stan-dard care group were finally included in the matching, and the matching effect of the two groups was good (L1 < 0.1). Before and after exposure, the average monthly opioid consumption in the palliative care group was significantly higher than that in the standard care group (Before exposure: 0.3 DDD/person-month vs. 0.1 DDD/person-month, P < 0.01; After exposure: 0.7 DDD/person-month vs. 0.1 DDD/person-month, P < 0.01; DDD refers to defined daily dose), palliative care significantly increased the average monthly opioid consumption in the patients (0.3 DDD/person-month, P < 0.01). The hospitalization rate (48.9% vs. 74.3%, P < 0.01) and operation rate (3.9% vs. 8.8%, P < 0.01) of the patients in palliative care group were significantly lower than those in standard care group, and the ICU rate became similar between the two groups (1.1% vs. 1.6%, P=0.634). Palliative care significantly reduced the patients ' hospitalization rate (-25.6%, P < 0.01), ICU rate (-4.9%, P < 0.01) and operation rate (-14.5%, P < 0.01). Before and after exposure, the average monthly total costs of pal-liative care group were slightly higher than those of standard care group (Before exposure: 20 092.3 yuan vs. 19 132.8 yuan, P=0.725; After exposure: 9 719.8 yuan vs. 8 818.8 yuan, P=0.165). Palliative care increased the average monthly total cost by 2 208.8 yuan, but it was not statistically significant (P=0.316).
CONCLUSION
Palliative care can increase the opioid consumption in advanced cancer patients, reduce the rates of hospitalization, ICU and surgery, but has no significant effect on medical expenditure.

Given that ovarian stimulation is vital for assisted reproductive technology (ART) and results in elevated serum estrogen levels, exploring the impact of elevated estrogen exposure on oocytes and embryos is necessary. We investigated the effects of various ovarian stimulation treatments on oocyte and embryo morphology and gene expression using a mouse model and estrogen-treated mouse embryonic stem cells (mESCs). Female C57BL/6J mice were subjected to two types of conventional ovarian stimulation and ovarian hyperstimulation; mice treated with only normal saline served as controls. Hyperstimulation resulted in high serum estrogen levels, enlarged ovaries, an increased number of aberrant oocytes, and decreased embryo formation. The messenger RNA (mRNA)-sequencing of oocytes revealed the dysregulated expression of lysine-specific demethylase 6b (Kdm6b), which may be a key factor indicating hyperstimulation-induced aberrant oocytes and embryos. In vitro, Kdm6b expression was downregulated in mESCs treated with high-dose estrogen; treatment with an estrogen receptor antagonist could reverse this downregulated expression level. Furthermore, treatment with high-dose estrogen resulted in the upregulated expression of histone H3 lysine 27 trimethylation (H3K27me3) and phosphorylated H2A histone family member X (γ-H2AX). Notably, knockdown of Kdm6b and high estrogen levels hindered the formation of embryoid bodies, with a concomitant increase in the expression of H3K27me3 and γ-H2AX. Collectively, our findings revealed that hyperstimulation-induced high-dose estrogen could impair the demethylation of H3K27me3 by reducing Kdm6b expression. Accordingly, Kdm6b could be a promising marker for clinically predicting ART outcomes in patients with ovarian hyperstimulation syndrome.
