Chaihu Guizhi Ganjiangtang （CGG）is a classic prescription in the Treatise on Cold Damage，which has the effects of clearing and relieving stagnation heat in Shaoyang，warming and dissolving water drink，and relieving the pivot mechanism. It is a classic prescription for treating spleen deficiency and liver depression and stopping internal stagnation caused by water drink. The formula is exquisite and well-matched and is often modified and used by ancient and modern medical practitioners to treat various miscellaneous diseases of internal and external medicine，with significant therapeutic effects. In recent years，with the rapid development of modern pharmacology，research on the micro mechanism of CGG has been continuously developed and deepened，providing new ideas for the treatment of diseases with CGG. Therefore，the authors systematically searched databases such as China National Knowledge Infrastructure，Wanfang Data Knowledge Service Platform，VIP Database， and PubMed for literature on the clinical application and pharmacological mechanism of CGG published by Chinese and foreign scholars in recent years. This article summarized the literature from two aspects：the modern clinical application and mechanism of action of CGG and elaborated on the diseases treated by CGG in modern literature，involving digestive system，respiratory system，nervous system，endocrine system，circulatory system，urinary system，gynecology，as well as its application in reducing the side effects of radiotherapy and chemotherapy， gynecology， dermatology， ophthalmology， and orthopedics. At the same time，the mechanism of CGG in treating diseases may be related to anti-inflammatory，anti-oxidative stress， regulation of immunity， anti-fibrosis， anti-tumor， improvement of gastrointestinal flora and motility， protection of liver tissue， reduction of blood lipids and blood sugar， and regulation of hormone levels.

ObjectiveTo investigate the mechanism of the modified of Bazhentang combined with Guishentang in improving pregnancy outcomes in mouse models of embryo implantation dysfunction by regulating T helper 1/T helper 2 （Th1/Th2） immune balance. MethodsEighty ICR female mice were randomly divided into four groups （n=20 per group） on gestational day 1 （GD1）： control， model， western medicine， and traditional Chinese medicine （TCM） groups. Except for the control group， all mice received mifepristone solution （0.2 mg/mouse） via oral gavage on GD4 to induce embryo implantation dysfunction. The TCM group received a water decoction of the modified of Bazhentang combined with Guishentang （20.8 g·kg^-1）， with the western medicine group administered dydrogesterone （3.9 mg·kg^-1）， and the control/model groups given equal volumes of saline. All treatments were administered once daily from GD1 until one day before sample collection. Outcomes included implantation site counts （macroscopic observation）， pregnancy rates， body weight， endometrial histopathology （hematoxylin-eosin staining）， uterine expression of T-box expressed in T cells （T-bet）， GATA-binding protein 3 （GATA3）， interferon gamma （IFN-γ）， and interleukin-4 （IL-4） at protein （Western blot） and mRNA （real-time polymerase chain reaction， Real-time PCR） levels， serum IFN-γ and IL-4 levels （enzyme-linked immunosorbent assay， ELISA）， and Th1/Th2 immune balance evaluated by calculating T-bet/GATA3 and IFN-γ/IL-4 ratios. ResultsCompared to the control group， the model group showed no significant change in pregnancy rate but exhibited a marked reduction in average implantation sites and body weight （P<0.01）. Histopathological analysis revealed endometrial abnormalities， including decreased glandular density， stromal compaction， and absence of nucleolar vacuoles. At the molecular level， uterine tissue in the model group demonstrated significantly upregulated expression of T-bet and IFN-γ （P<0.05， P<0.01）， alongside markedly downregulated GATA3 and IL-4 expression （P<0.05， P<0.01）. Serum analysis confirmed markedly elevated IFN-γ （P<0.01） and reduced IL-4 levels （P<0.01）， resulting in significantly increased T-bet/GATA3 and IFN-γ/IL-4 ratios （P<0.01）. Compared to the model group， pregnancy rates in all treatment groups showed no significant change. Implantation sites and body weight increased substantially （P<0.01）， with restored endometrial morphology characterized by enhanced glandular density， stromal edema， and reappearance of nucleolar vacuoles. Significant downregulation of T-bet and IFN-γ （P<0.01） and upregulation of GATA3 and IL-4 （P<0.05， P<0.01） in uterine tissue were observed. Serum IFN-γ levels were significantly reduced （P<0.05， P<0.01）， while IL-4 levels were significantly elevated （P<0.05）. The Th1/Th2 ratios were significantly decreased （P<0.01）. ConclusionThe modified of Bazhentang combined with Guishentang significantly enhances the number of embryo implantation sites in mice with embryo implantation dysfunction， potentially through modulating T-bet/GATA3 expression， restoring Th1/Th2 immune balance， and improving endometrial receptivity.

Objective To systematically analyze the medical radiation exposure levels in a district of Ningbo City and to provide a scientific basis for the reasonable and effective control of medical radiation exposure. Methods Based on the radiological diagnosis frequency and dose information system, basic medical radiation exposure data were collected, such as radiation doses received by patients in various X-ray diagnostic examinations, from all 13 public medical institutions in a district of Ningbo City from January 1 to December 31, 2020. The data were analyzed for the percentage and collective effective dose of various diagnostic examinations, the distribution of examinations by sex and age, and the number of patients undergoing two or more examinations and their cumulative doses within multiple time intervals. Results Among medical X-ray diagnostic examinations in the district, the percentages of CT examination and routine photography examination were 50.88% and 47.93%, respectively, and the collective effective dose of CT examination accounted for 97.75%. By age and sex, the frequency of examination was the highest in the age group of 45-54 years, and the frequency of examination in the male was higher than that in the female before age 55. The annual effective dose for two patients exceeded 100 mSv. Conclusion In this study, CT examination accounted for up to 50.88% of all medical X-ray diagnostic examinations, and contributed 97.75% of the collective effective dose, highlighting the need for particular attention to the justification of medical radiation exposure from CT.

Objective To understand the individual radiation dose levels and changes of occupational external exposure among radiation workers in a steel group from 2020 to 2023, and to provide a basis for strengthening radiation protection in the group. Methods According to the Specifications for individual monitoring of occupational external exposure (GBZ 128-2019), individual monitoring was conducted using a thermoluminescent dosimeter, with each monitoring cycle lasting 90 days, totaling four cycles per year. Individual monitoring data of occupational external exposure among radiation workers in the steel group from 2020 to 2023 were collected for statistical analysis. Results A total of 5889 monitoring records were collected from radiation workers across 37 affiliated units of the steel group during the period of 2020-2023. The average annual effective dose was 0.150 mSv, the maximum annual effective dose was 3.84 mSv, and 0.3% monitored workers showed annual effective doses exceeding 1 mSv. The average annual effective dose in 2023 was 0.146 mSv, which was lower than in 2020 but higher than in 2021 and 2022 (Z = −6.657 to 14.129, P < 0.001). The number of monitored workers in industrial and medical sectors accounted for 86.9% and 13.1%, respectively. Their average annual effective doses were 0.152 mSv and 0.140 mSv, respectively, and the difference was statistically significant (Z = −7.969, P < 0.001). In the industrial sector, the average annual effective dose for the monitored workers in industrial radiography was significantly higher than other occupations (Z = −8.094, P < 0.001). There was a significant difference in average annual effective dose among workers of different occupational categories in the medical sector (H = 67.040, P < 0.001). The average annual effective doses were relatively high for diagnostic radiology and nuclear medicine. Additionally, the average annual effective doses for male and female radiation workers were 0.150 mSv and 0.152 mSv, respectively (P > 0.05). Conclusion The average annual effective dose of radiation workers in the steel group was at low levels for four consecutive years, which meet the requirements of the national standard. However, to maintain the individual radiation dose levels of radiation workers as low as reasonably achievable, it remains necessary to strengthen radiation protection management in the steel group.

Objective To investigate the levels and influencing factors for eye lens dose of interventional radiology workers, and to provide a basis for reasonable and scientific radiation protection. Methods Thermoluminescent eye lens dosimeters were used to monitor the left and right eye lens doses of interventional radiology workers in real time during different surgical positions and varying eye protection conditions. The annual eye lens doses for the operators were estimated based on their yearly workload. The differences in eye lens doses under different conditions were analyzed and the influencing factors were identified. Results For individual interventional operations, the range of personal dose equivalent H_p(3) of the left eye of interventional radiology workers was ( < MDL ~ 418.33) μSv, the median (Q₁, Q₃) was 9.29 ( < MDL, 40.79) μSv, and the mean was 40.79 ± 70.36 μSv. The estimated annual eye lens doses were 4.05 mSv and 17.80 mSv based on the median and mean values of the eye lens dose of a single operation multiplied by average annual frequency of operations per person, respectively. The left eye lens dose was higher than the right eye lens dose of the same operator (Z = −4.24, P < 0.05), and the dose of the right eye lens was strongly positively correlated with that of the left eye lens. The left eye lens dose of the first surgeon was higher than that of the second surgeon in the same operation (Z = −3.10, P < 0.05). The eye lens dose was influenced by operator position (χ² = 9.149, P = 0.002, OR = 8.343), eye protection (χ² = 4.619, P = 0.032, OR = 4.352), and air kerma area product (χ² = 8.032, P = 0.005, OR = 5.488). Conclusion According to the results of this study, a significant portion of interventional operators have eye lens doses that approach or exceed international occupational dose limits. It is recommended to pay attention to the operation frequency of the first operator and the air kerma area product of interventional operation, and strengthen radiation protection and dose monitoring for the eye lens of interventional radiology workers.

Objective: To analyze the association of mother-child interaction and screen exposure of preschool children with psychological and behavioural problems, so as to provide guidance for promoting the psychological development of preschool children. Methods: From November to December 2024, a convenience cluster sampling method was used to survey 2 977 mothers of preschool children in Daguan and Yingjiang districts of Anqing City. The Chinese Parent-Child Interaction Scale (CPCIS) was applied to evaluate the quality of mother-child interaction, and the Conners Parent Symptom Questionnaire (PSQ) was used to assess the psychological and behavioral problems of preschool children. Binary Logistic regression was applied to analyze the association of mother-child interaction, screen exposure and their combined effect on psychological and behavioral problems among preschool children. Results: The detection rate of psychological and behavioral problems among preschool children was 13.9%. Binary Logistic regression results showed that low scores of mother-child interaction ( OR=2.31, 95%CI =1.72-3.11) and high screen exposure ( OR= 1.52 , 95%CI =1.23-1.88) were higher risks for psychological and behavioral problems in preschool children; the results of the combined effect showed that preschool children in low scores of mother-child interaction and low screen exposure group ( OR=2.18, 95%CI =1.46-3.28), low scores of mother-child interaction and high screen exposure group ( OR=3.13, 95%CI =2.10- 4.65 ) had significantly higher risks of abnormal detection in psychological and behavioral problems, compared to those in the high scores of mother-child interaction and low screen exposure group respectively (all P <0.05). Conclusions Both screen exposure and mother- child interaction are associated with psychological and behavioral problems in preschool children. High quality mother-child interaction can relieve the adverse effects of screen exposure on preschool children s psychological and behavioral development.
