Objective To discuss the curative effect of hepatic arterial infusion chemotherapy(HAIC)combined with programmed death receptor-1(PD-1)inhibitors and anti-angiogenesis therapy for BCLC stage C hepatocellular carcinoma(HCC).Methods The patients with HCC of BCLC stage C,who received HAIC combined with PD-1 inhibitors and anti-angiogenesis therapy at the First Affiliated Hospital of Soochow University of China from January 2021 to December 2023,were collected for this study.The time from the start of treatment to complete remission(CR)of disease,the dynamic changes in alpha-fetoprotein(AFP)levels and the recurrence during follow-up period were analyzed.The relevant literature of the above triple regimen for HCC was searched from PubMed database and its curative effect was analyzed.Results Of the 214 HCC patients treated with triple therapy regimen,9(4.2％)achieved CR.The time from the start of treatment to CR was 2-10 months.The patients were followed up for 5-20 months.The time of AFP level returning to normal value was from 79 to 259 days.One patient developed recurrence 10 months after CR,and the other 8 patients maintained the CR status.A total of 12 articles were retrieved,the reported CR rates ranged from 0 to 16.5％.Conclusion A CR can be achieved in a few patients with advanced HCC treated with HAIC combined with PD-1 inhibitors and anti-angiogenesis therapy.

Objective To analyze the expression and clinical significance of stimulator of interfer-on genes(STING),C-C motif chemokine ligand 5(CCL5),interferon regulatory factor 3(IRF3)and programmed death ligand-1(PDL1)in squamous cell lung cancer.Methods A total of 56 pa-tients with squamous cell lung cancer were enrolled.Resected tumor tissues and adjacent non-tumor tissues(located more than 5 cm from the tumor margin)were collected.Immunohistochemical staining was performed to detect the expression of STING,CCL5,IRF3 and PDL1.The correlations of STING,CCL5,IRF3 and PDL1 with clinical data were analyzed.The relationship between the expression of STING,CCL5,IRF3 and PDL1 in lung squamous cell carcinoma tissues and prognosis was also evalua-ted.The prognostic factors of patients with lung squamous cell carcinoma were analyzed.Results The positive rate of STING expression in lung squamous cell carcinoma tissues was significantly lower than that in adjacent non-tumor tissues,whereas the positive rates of CCL5,IRF3 and PDL1 were significantly higher(P＜0.05).The expression levels of STING,CCL5,IRF3 and PDL1 were associated with tumor diameter,TNM stage,lymph node metastasis and differentiation degree(P＜0.05).The 3-year survival rate of STING positive expression patients was significantly higher than that of STING negative expression patients(P＜0.05).The 3-year survival rate of CCL5 positive,IRF3 positive and PDL1 positive expression patients was significantly lower than that of CCL5 negative,IRF3 negative and PDL1 negative expression patients(P＜0.05).STING,CCL5,IRF3 and PDL1 were identified as prognostic factors for patients with squamous cell lung cancer(P＜0.05).Conclusion In squamous cell lung cancer tissues,STING is expressed at low levels,while CCL5,IRF3 and PDL1 are ex-pressed at high levels.These findings have significant clinical value in assessing the prognosis of pa-tients with squamous cell lung cancer.

ObjectiveTo investigate the preventive and therapeutic effects of Tiaogan Huaxian pills combined with entecavir on hepatic fibrosis in chronic hepatitis B with liver Qi stagnation， spleen deficiency， and blood stasis syndrome and its effect on diffusion-weighted imaging （DWI）. MethodClinical data of 117 patients with liver disease who visited the Department of Hepatology at the First Affiliated Hospital of Guangxi University of Chinese Medicine from January 2021 to April 2022 were retrospectively analyzed. According to different treatment plans， they were divided into a control group （59 cases） and a treatment group （58 cases）. Both groups of patients received entecavir-based etiology treatment， and the treatment group added Tiaogan Huaxian pills on the basis of basic treatment. Both groups were treated for 24 weeks. Before and after treatment， the two groups were compared in terms of alanine aminotransferase （ALT）， advanced surgical technologies （AST）， total bilirubin （TBil）， hepatitis B virus （HBV）-DNA conversion rate， liver stiffness measurement （LSM）， four items of liver fibrosis （hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， and laminin）， the fibrosis index based on four factors （FIB-4）， the aspartate aminotransferase to platelet ratio index （APRI）， the apparent diffusion coefficient （ADC） value in magnetic resonance imaging （MRI）， and traditional Chinese medicine symptom scores， so as to analyze the efficacy of the two groups. ResultBefore treatment， there was no significant difference in ALT， AST， TBil， LSM， four items of liver fibrosis， FIB-4， APRI， HBV-DNA conversion rate， ADC value， and traditional Chinese medicine symptom scores between the two groups. After treatment， both groups of patients showed significant reductions in ALT， AST， TBil， LSM， hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， laminin， FIB-4， and APRI （P<0.05） and a significant increase in ADC value （P<0.05） and HBV-DNA conversion rate （P<0.01）. The traditional Chinese medicine symptom score of the treatment group decreased significantly （P<0.05）. Compared with the control group after treatment， the effective rate of clinical traditional Chinese medicine in the treatment group was 91.38% （53/58）， which was significantly higher than that of the control group （54.23%， 32/59） （Z=-4.325， P<0.01）. In the treatment group， ALT， AST， TBil， LSM， hyaluronidase， type Ⅲ pro-collagen， type Ⅳ collagen， laminin， FIB-4， APRI， and traditional Chinese medicine symptom scores all decreased significantly （P<0.05）， and the increase in ADC values was more significant （P<0.05）， while the difference in HBV-DNA conversion rate was not statistically significant. There were no serious adverse reactions or events in either group. ConclusionTiaogan Huaxian pills combined with entecavir have significant clinical efficacy in the treatment of hepatic fibrosis in chronic hepatitis B， which can reduce liver inflammation activity， delay hepatic fibrosis progression， and reduce traditional Chinese medicine symptom scores. It is worthy of clinical promotion and application.

Objective:To investigate the sleep status of preschool children with a coordination development disorder (DCD).Methods:Implementing stratified cluster sampling, 38, 900 questionnaires were distributed in 1000 classes of 200 kindergartens randomly selected in 11 prefecture-level cities of China′s Zhejiang Province. A total of 35, 464 valid responses were returned. On the basis of the responses, 2251 of the children were of (6.35%) were deemed DCD-positive, while the rest formed a DCD-negative group. The Children′s Family Social Environment and Sleep Health Questionnaire (1-6 years old) and the children′s sleep habits questionnaire were employed to investigate their sleep status.Results:①Regular sleeping time and duration, and falling asleep within 20 minutes were significantly less common in the DCD-positive group. In the negative group, shifting sleep place at night, finding it hard to sleep in strange environments, waking up ≥2 times a night, being awoken by others in the morning, difficulty in waking up and getting up in the morning, and bad mood after waking were significantly less frequent. ②In addition to delayed bedtime, the incidence of refusal to go to bed, fear of sleeping in the dark or alone, bedwetting, restless sleep, sleepwalking, talking in sleep, being awakened by nightmares, teeth grinding, loud snoring, apnea, dyspnea, crying and sweating after waking up at night, and insufficient sleep were all significantly higher in the DCD-positive group. ③The DCD-positive group also reported more sleeping in the daytime on weekends, more time on playing electronic products along with shorter sleep duration at night. There was, however, no significant difference between the two groups in sleep duration on school days and all day on weekends.Conclusion:Preschool children with a DCD have different sleep habits from those developing normally. They are more likely to suffer from sleep problems which affect their sleep duration.

Objective To investigate the efficacy of continuous hepatic arterial infusion chemotherapy (HAIC) with the FOLFOX regimen and its multimodality therapeutic regimen in the treatment of patients with advanced hepatocellular carcinoma, as well as the influencing factors for prognosis. Methods A retrospective analysis was performed for the clinical data of 66 patients with advanced hepatocellular carcinoma who received continuous HAIC with FOLFOX regimen in Nanfang Hospital, Southern Medical University, from September 2018 to November 2021. The patients were observed in terms of objective response rate (ORR), disease control rate (DCR), median progression-free survival (mPFS), and median overall survival (mOS) after treatment, and treatment-related adverse reactions were recorded. For the patients with portal vein tumor thrombus, the effect of the treatment on portal vein tumor thrombus was assessed. The Kaplan-Meier method was used for survival analysis, and the Cox regression analysis was used to investigate the influencing factors for prognosis. Results According to the RECIST1.1 criteria, FOLFOX-HAIC and its multimodality therapeutic regimen achieved an ORR of 33.3% (22/66) and a DCR of 86.4% (57/66) in the treatment of 66 patients with advanced hepatocellular carcinoma, with an mPFS time of 8.2 months and an mOS time of 22.1 months. Among the 39 patients with portal vein tumor thrombus, 2 achieved complete remission, 8 achieved partial remission, 24 achieved stable disease, and 5 had disease progression, with an ORR of 25.6% (10/39) and a DCR of 87.2% (34/39). The main adverse reactions included gastrointestinal reactions (16.7%, 11/66), pyrexia (12.1%, 8/66), liver area pain (10.6%, 7/66), bone marrow suppression (3.0%, 2/66), and contrast agent allergy (3.0%, 2/66), and there were no grade > Ⅳ toxic or side effects or deaths caused by such complications. The Cox regression analysis showed that extrahepatic metastasis (hazard ratio [ HR ]=2.668, 95% confidence interval [ CI ]: 1.357-5.245, P < 0.05) and prothrombin time (PT) ( HR =1.282, 95% CI : 1.080-1.630, P < 0.05) were independent risk factors for PFS, and aspartate aminotransferase level ( HR =1.008, 95% CI : 1.002-1.013, P < 0.05) and PT ( HR =1.303, 95% CI : 1.046-1.630, P < 0.05) were independent risk factors for OS. Conclusion FOLFOX-HAIC and its multimodality therapeutic regimen has a certain clinical effect with controllable adverse reactions in the treatment of advanced hepatocellular carcinoma.

Objective:To analyze the clinical and pathological characteristics of chronic hepatitis B (CHB) patients with normal alanine aminotransferase (ALT) and not receiving antiviral therapy.Methods:This study retrospectively included CHB patients diagnosed by liver biopsy at the Third Hospital of Hebei Medical University from January 2008 to December 2022. According to the HBV DNA and HBeAg status of "immune tolerance period and immune control period", these patients were divided into three groups: chronic HBV carrier group, inactive HBsAg carrier group and indeterminate group including the patients that did not meet the inclusion criteria of the above two groups. Kruskal-Wallis H test was used for comparison of continuous data between multiple groups. Mann-Whitney U test was used for comparison of continuous data and ordered categorical data between two groups. Chi-square test or Fisher′s exact test was used for comparison of categorical data between two groups. Results:A total of 284 CHB patients with normal ALT were enrolled. There were 64, 88 and 132 cases in the chronic HBV carrier group, inactive HBsAg carrier group and indeterminate group, respectively. Histopathological analysis revealed that there were 182 (64.08%) cases with pathological inflammation grade (G) and/or fibrosis stage (S)≥2, 155 (54.58%) with S≥2 and 120 (42.25%) with G≥2. The proportion of patients with G and/or S≥2 in the indeterminate group [70.45% (93/132)] was higher than that in the chronic HBV carrier group [48.44% (31/64)] and inactive HBsAg carrier group [65.91% (58/88)] (both P<0.05). Patient′s age and the ratio of patients with S≥2 in the chronic HBV carrier group [33 years old, 39.06% (25/64)] were smaller than those in the inactive HBsAg carrier group [39 years old, 56.82% (50/88)] and the indeterminate group [39 years old, 60.61% (80/132)] (all P<0.05). Patients in the inactive HBsAg carrier group (19 U/L) had lower ALT levels than those in the chronic HBV carrier group (26 U/L) and the indeterminate group (23 U/L) (both P<0.05). The proportion of patients with cytoplasmic/cytoplasmic nuclear-type HBcAg was higher in patients with G and/or S≥2 than in patients with G and S<2 [73.08% (57/78) vs 32.08% (17/53), P<0.05], and the proportion of patients with cytoplasmic/cytoplasmic nuclear-type HBcAg increased gradually with age. The proportion of patients with cytoplasmic/cytoplasmic nuclear-type HBcAg was higher in patients with G and/or S≥2 than in patients with G and S<2 in the chronic HBV carrier status and indeterminate groups [93.33% (28/30) vs 43.33%(13/30), P<0.05; 59.46% (22/37) vs 12.50% (2/16); both P<0.05]. There was a statistically significant difference in the incidence of significant liver injury between patients≤ 30 years old and >30 years old [52.7% (39/74) vs 68.1% (143/210), P<0.05]. Conclusions:Significant liver injury occurred in 64.08% (182/284) of CHB patients with normal ALT not receiving antiviral therapy, which required the attention of clinicians. Among CHB patients with normal ALT, the expression site of HBcAg in hepatocytes was related to the occurrence of significant liver injury and could be expected to serve as an important indicator for predicting the patient′s status and the necessity of antiviral treatment. CHB patients with positive HBV DNA who were older than 30 years required antiviral treatment, and CHB patients≤30 years with normal ALT and significant hepatic tissue damage also required antiviral treatment.

Hyperuricemic nephropathy （HN）， a secondary renal damage common in clinical practice， is characterized by early concealing and continuous progression. The understanding of HN in traditional Chinese medicine （TCM） is from a macroscopic perspective. According to the TCM theory， HN is caused by the combination of external pathogens and internal injuries， with the main pathogenesis being root deficiency combined with superficial excess and deficiency-excess in complexity. In western medicine， the understanding of HN is from the microscopic perspective， which holds that the occurrence of HN is the result of inflammation， oxidative stress， renin-angiotensin-aldosterone system （RAAS） activation， and metabolic abnormalities. The TCM syndromes of HN include internal dampness and heat， obstruction in dampness and turbidity， deficiency of spleen and kidney， and deficiency of kidney yin. Accordingly， the prescriptions should clear heat and dampness， remove dampness and turbidity， tonify spleen and kidney， and nourish kidney yin， respectively. In addition to TCM prescriptions， single herbal medicines and their extracts， Chinese patent medicines， and external applications of Chinese medicines have played a significant role in the treatment of HN， promoting the application of TCM in the treatment of HN. Moreover， the integrated traditional Chinese and western medicine has also played a role in the treatment of HN， enriching the treatment schemes of HN. Different from common kidney diseases such as acute and chronic glomerulonephritis and nephrotic syndrome， HN with particularity should be carefully differentiated in clinical practice. This article systematically summarizes the research progress in the treatment of traditional Chinese medicine and integrated traditional Chinese and western medicine on hyperuricemic nephropathy with TCM and integrated traditional Chinese and western medicine， aiming to enrich the system and theory of HN treatment and further guide the clinical practice.
