Guided by the theory of "fire and original qi are restricted"， it is believed that original qi depletion is the root of the cutaneous immune-related adverse events （cirAEs） related to immune checkpoint inhibitors （ICIs）， and the yin fire exuberance is the branch. Among them， original qi depletion is the internal foundation of the disease， while the drug toxicity of ICIs harming original qi is the initiating factor， and exuberant yin fire is the key pathogenesis. In clinical practice， the general treatment principle advocates banking up original qi to consolidate the root and draining fire to raise yang. Buzhong Yiqi Decoction （补中益气汤） can be used to activate transportation of middle jiao （焦） and promote ascent and dispersion of clear yang， thereby restoring the balance of qi and fire， and medicinals such as Huangqin （Radix Scutellariae）， Huanglian （Rhizoma Coptidis） and Huangbai （Cortex Phellodendri Chinensis） can be supplementetd to clear and drain yin fire. At the same time， considering the accompanying symptoms such as dampness-stasis and fluids depletion， the methods of removing dampness and dispelling stasis， supplementing blood and nourishing yin should be added flexibly. This approach can provide a new perspective and treatment strategy for reducing ICIs-related cirAEs in malignant tumors.

Objective:To investigate the evaluation efficacy and predictive prognostic value of alpha-fetoprotein (AFP) response in tyrosine kinase inhibitors (TKIs) in combination with PD-1 inhibitors (α-PD-1) for intermediate-to-advanced hepatocellular carcinoma (HCC).Methods:The retrospective cohort study was conducted. The clinicopathological data of 205 patients with intermediate-to-advanced HCC who were admitted to 9 medical centers, including Mengchao Hepatobiliary Hospital of Fujian Medical University et al, from March 2020 to July 2022 were collected. There were 178 males and 27 females, aged (52±12)years. Based on AFP response at 6-8 weeks after treatment, patients were divided into the AFP response group (AFP level decreased by ≥50% compared to baseline) and the AFP no response group (AFP level decreased by <50% compared to baseline). Observation indicators: (1) AFP response evaluation of anti-tumor efficacy; (2) comparison of patient prognosis; (3) analysis of factors affecting patient prognosis. Measurement data with normal distrubution were represented as Mean± SD, and measurement data with skewed distribution were represented as M(range) and M( Q1, Q3). Count data were described as absolute numbers, and comparison between groups was conducted using the chi-square test. The Kaplan-Meier method was used to draw survival curve and calculate survival rate, and the Log-Rank test was used for survival analysis. The COX proportional risk model was used for univariate analysis and the COX stepwise regression model was used for multivariate analysis. Results:(1) AFP response evaluation of anti-tumor efficacy. Before treatment, all 205 patients were positive of AFP, with a baseline AFP level of 1 560(219,3 400)μg/L. All 205 patients were treated with TKIs in combination with α-PD-1, and the AFP level was 776(66,2 000)μg/L after 6 to 8 weeks of treatment. Of the 205 patients, 88 cases were classified as AFP response and 117 cases were classified as AFP no response. According to the response evaluation criteria in solid tumors version 1.1, the objective response rate (ORR) and disease control rate (DCR) were 42.05%(37/88) and 94.32%(83/88) in patients of the AFP response group and 16.24% (19/117) and 64.10% (75/117) in patients of the AFP no response group, showing significant differences between them ( χ2=16.846, 25.950, P<0.05). According to the modified response evaluation criteria in solid tumors, the ORR and DCR were 69.32% (61/88) and 94.32% (83/88) in patients of the AFP response group and 33.33% (39/117) and 64.10% (75/117) in patients of the AFP no response group, showing significant differences between them ( χ2=26.030, 25.950, P<0.05). (2) Comparison of patient prognosis. All 205 patients were followed up for 12.4(range, 2.4-34.0)months after treatment. The median progression free survival time and total survival time were 5.5 months and 17.8 months, respectively. The 1-year, 2-year progression free survival rates were 20.8% and 7.2%, and the 1-year, 2-year overall survival rates were 68.7% and 31.5%, respectively. The median progression free survival time, 1-year and 2-year progression free survival rates were 9.7 months, 39.6% and 14.2% in patients of the AFP response group and 3.7 months, 7.8% and 2.0% in patients of the AFP no response group, showing a significant difference in progression free survival between them ( χ2=43.154, P<0.05). The median overall survival time, 1-year and 2-year overall survival rates were not reached, 85.2% and 56.3% in patients of the AFP response group and 14.6 months, 56.3% and 14.5% in patients of the AFP no response group, showing a significant difference in overall survival between them ( χ2=33.899, P<0.05). (3) Analysis of factors affecting patient prognosis. Results of multivariate analysis showed that invasion of large blood vessels, extrahepatic metastasis, combined hepatic artery intervention therapy, and AFP response were independent factors influencing progression free survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1 ( hazard ratio=1.474, 1.584, 0.631, 0.367, 95% confidence interval as 1.069-2.033, 1.159-2.167, 0.446-0.893, 0.261-0.516, P<0.05), and Eastern Cooperative Oncology Group score, invasion of large blood vessels, extrahepatic metastasis, and AFP response were independent factors influencing overall survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1 ( hazard ratio= 1.347, 1.914, 1.673, 0.312, 95% confidence interval as 1.041-1.742, 1.293-2.833, 1.141-2.454, 0.197-0.492, P<0.05). Conclusions:AFP response at 6-8 weeks after treatment can effectively evaluate anti-tumor efficacy of TKIs in combination with α-PD-1 for intermediate-to-advanced HCC. AFP response is the independent factor influencing progression free survival and overall survival in patients with intermediate-to-advanced HCC who were treated with TKIs in combination with α-PD-1.

Objective: To analyze the correlation between refractive errors and physical development indicators among primary school students aged 6 to 9, so as to provide a scientific basis for the development of effective prevention and control measures. Methods: A stratified cluster random sampling method was used to recruit 2 833 elementary school students aged 6 to 9 from Guangdong Province for vision screening, ocular biometry, and physical examinations in Octorber, 2020. The Chi square test, t-test, and ANOVA were employed to compare myopia rates and indicator values across different groups. Multiple linear regression models were used to analyze the correlations between height, weight, and body mass index (BMI) with refractive development indicators. Results: The screening myopia rate among primary school students aged 6 to 9 was 16.7%, and the myopia rate increased with age ( χ 2= 51.58 , P <0.01). The height and weight of the myopic group [(126.96±7.41)cm, (26.59±6.45)kg] were higher than those of the non myopic group [(124.76±7.77)cm, (25.42±5.87)kg] ( t =5.84, 3.65, P <0.01). The mean values of spherical equivalent (SE), axial length (AL), anterior chamber depth (ACD), and AL/corneal curvature radius (CR) ratio for students aged 6 to 9 were (-0.17±1.04)D, (22.96±0.78)mm, (3.38±0.24)mm, and (2.95±0.08), respectively, with statistically significant differences across different age and myopia severity groups ( t =37.08, 119.20, 41.54, 133.60; 935.30, 184.10, 73.95, 498.50, P < 0.01). After adjusting for gender, age, and residence, the multiple linear regression model showed that height was positively correlated with AL and CR, weight was positively correlated with ACD, and BMI was positively correlated with AL and ACD ( β = 0.191 , 0.070, 0.035, 0.013, 0.007, P <0.05). When stratified by myopia status, results for the non-myopic group were similar to the overall results, whereas in the myopic group, the correlations between height, BMI, and AL were not statistically significant ( P > 0.05). Conclusions Among primary school students aged 6 to 9, height and BMI are positively correlated with AL in the non myopic group but no similar correlation is observed in the myopic group, indicating that factors other than physical development, such as environmental and behavioral factors, should be considered for their impact on refractive development.

Based on the theory of "one qi circulation" founded by HUANG Yuanyu， the core disease mechanism of colorectal cancer is the innate spleen deficiency and stomach qi failing to bear downward， which leads to the turbidity assemble in large intestine， forming the carcinoma toxin， and ultimately transforms into colorectal cancer. The treatment should base on recovering the circulation of qi， Huangya Decoction （黄芽汤） as the basic formula， the circulation of qi ascending and descending as the base， adjusting ascending and descending together with Xiaqi Decoction （下气汤）， and differentiating the syndrome on yin-yang excess-deficiency； for spleen-kidney yang deficiency syndrome， treated with Tianhun Decoction （天魂汤） to supplement liver， kidney and assist yang； for liver-kidney yin deficiency syndrome， treated wtih Dipo Decoction （地魄汤） to supplement lung， kidney， and assist yang. They jointly prompt one qi circulation to provide the thoughts for the treatment of colorectal cancer by traditional Chinese medicine.

【Objective】 To explore the effects and mechanism of p38 mitogen activated protein kinase (MAPK) pathway on the formation of calcium oxalate (CaOx) kidney stones in rats,so as to provide new ideas for the treatment of kidney stones. 【Methods】 A total of 40 rats were divided into control, SB203580, CaOx and SB203580+CaOx groups, with 10 rats in each group.Intragastric administration of a mixture of 1% ethylene glycol and 1% ammonium chloride was given to the CaOx and SB203580+CaOx groups to construct CaOx models, while intragastric administration of drinking water was given to the control and SB203580 groups.After molding, SB203580 and SB203580+CaOx groups were injected with 5 mg/kg SB203580 peritoneally once a day for 14 days, while the control and CaOx groups were injected with equal volume of normal saline.The renal mass of rats was measured and the renal coefficient was calculated; the serum levels of blood urea nitrogen (BUN) and serum creatinine (SCr) were measured with an automated biochemical analyzer; the urinary levels of neutrophil gelatinase-associated lipid carrier protein (NGAL) and kidney injury molecule-1 (KIM-1) were determined with enzyme-linked immunosorbent assay (ELISA); the crystal deposition and tissue damage in renal tissues were observed with Von Kossa staining; the apoptosis of renal tubule cells was observed with TUNEL; the expressions of autophagy markers in kidney tissues were detected with immunohistochemical staining; the molecular expressions of autophagy-endoplasmic reticulum stress related pathways in renal tissues were determined with RT-qPCR and Western blot. 【Results】 Compared with the CaOx group, the SB203580+CaOx group had increased body mass after molding (P<0.05); decreased kidney mass, kidney coefficient, BUN, SCr, NGAL and KIM-1 levels (P<0.05); alleviated pathological damage of kidney tissues; significantly reduced black crystal; down-regulated proportion of positive TUNEL cells, positive expression area of LC3B and Beclin-1, mRNA expressions of LC3B, Beclin-1, CHOP and GRP78, protein ratio of LC3-Ⅱ/LC3-Ⅰ, and protein expressions of Beclin-1, CHOP and GRP78 (P<0.05); but up-regulated mRNA and protein expressions of p62 (P<0.05). 【Conclusion】 The p38 MAPK pathway is involved in the formation of CaOx kidney stones in rats.Inhibition of this pathway can reduce the formation of kidney stones, which may be related to the regulation of autophagy and endoplasmic reticulum stress.

Objective To study the application of serum microRNA(miR)-338-3p and miR-495-3p levels in the diagnosis and disease evaluation of severe adenovirus pneumonia in children.Methods A total of 130 chil-dren with adenovirus pneumonia who were treated in Cangzhou Central Hospital from November 2020 to No-vember 2022 were enrolled as an observation group.According to the severity of the disease,the children were divided into a mild pneumonia group with 90 children and a severe pneumonia group with 40 children.A total of 130 healthy children who were examined in Cangzhou Central Hospital during the same period were en-rolled as the control group.The observation and control groups and the children with different disease severity were compared in terms of the serum levels of miR-338-3p and miR-495-3p.Receiver operating characteristic(ROC)curve was used to analyze the diagnostic value of serum miR-338-3p and miR-495-3p for severe adeno-virus pneumonia.Multivariate Logistic regression was used to analyze the influencing factors of severe adeno-virus pneumonia.Results The observation group had a significantly lower serum level of miR-338-3p and a significantly higher serum level of miR-495-3p than the control group(P＜0.05).There were significant differences in electrolyte disturbance,circulatory system complications incidence,miR-338-3p level,miR-495-3p level,sequential organ failure score and Murray lung injury score between the mild pneumonia group and the severe pneumonia group(P＜0.05).ROC curve analysis showed that the area under the curve(AUC)of serum miR-338-3p and miR-495-3p in the auxiliary diagnosis of severe adenovirus pneumonia were 0.745(95％CI 0.662-0.828)and 0.774(95％CI 0.685-0.863),respectively.And the AUC of the combination of the two was 0.884(95％CI 0.821-0.946),which was better than that of each index alone(Z=2.593,1.963,P＜0.05).Conclusion The level of serum miR-338-3p is decreased and the level of serum miR-495-3p is increased in children with severe adenovirus pneumonia.The combined detection of miR-338-3p and miR-495-3p has a certain value in the diagnosis of severe adenovirus pneumonia and can be used as a serum indica-tor to evaluate the severity of severe adenovirus pneumonia.
