Thyroid diseases are common clinical endocrine disorders， and their pathogenesis is generally considered to be closely related to genetic predisposition factors， immune system disorders， hormone levels， etc. Xiaoyaosan is widely used in the treatment of various thyroid diseases with excellent effects. This study summarized the relevant literature on the treatment of thyroid diseases with modified Xiaoyaosan prescriptions and their active ingredients from aspects such as theoretical analysis， clinical research， and mechanism research. Theoretical analysis revealed that Xiaoyaosan could not only disperse stagnated liver qi but also replenish deficient spleen Qi， which was consistent with the etiology and pathogenesis of thyroid diseases. Clinical studies found that Xiaoyaosan and its modified prescriptions could be widely used in the treatment of multiple thyroid diseases， such as hyperthyroidism， Hashimoto's thyroiditis， and thyroid nodules. Both the use of modified Xiaoyaosan alone and in combination with medications such as methimazole， propylthiouracil， and euthyrox could effectively improve patients' clinical symptoms. In the mechanism research， this study discovered that the whole formula of Xiaoyaosan and its modified prescriptions could inhibit inflammatory reactions， regulate immune balance， and delay liver damage during the treatment of thyroid diseases. The research on Xiaoyaosan for treating thyroid diseases mainly focused on thyroid cancer， autoimmune thyroiditis， hyperthyroidism， and hypothyroidism. The mechanisms of action mainly involved promoting cell apoptosis， inhibiting cell proliferation and migration， arresting the cell cycle， and regulating thyroid hormone levels. In conclusion， this study systematically combs and summarizes the research status of Xiaoyaosan in treating thyroid diseases through literature retrieval， aiming to provide new perspectives and new ideas for the prevention and treatment of thyroid diseases with traditional Chinese medicine.

BackgroundPerceived discrimination has been identified as a main risk factor for depression in maintenance hemodialysis patients. Chronic Illness Rejection and Discrimination Scale （CIRDS） is a measure for assessing perceived discrimination in individuals with chronic disease. However， the Chinese version of CIRDS for maintenance hemodialysis patients has not yet been established. ObjectiveTo translate CIRDS into Chinese version and evaluate its reliability and validity in maintenance hemodialysis patients， so as to provide an effective tool for assessing the perceived discrimination among maintenance hemodialysis patients. MethodsThe Brislin's model for translation， back-translation， cross-cultural adaptation and pre-experimentation was utilized to develop a Chinese version of CIRDS. A coherent of 250 maintenance hemodialysis patients attending Taihe Hospital Affiliated to Hubei Medical College， from July to October 2023 were selected as the research subjects. The formal scale was refined by employing item analysis， exploratory factor analysis and confirmatory factor analysis. The validity of the scale was evaluated using content validity and construct validity. The reliability of the scale was evaluated using Cronbach's α coefficient， test-retest reliability and split-half reliability. ResultsThe Chinese version of CIRDS consisted of 11 items， including 2 factors （perceived discrimination and perceived rejection）. The scale-level content validity index （S-CVI） value was 0.898 and the item-level content validity index （I-CVI） values ranged from 0.875 to 1.000. Two common factors were extracted by exploratory factor analysis and explained 65.41% of the total variance. Confirmatory factor analysis also indicated that the model provided a good fit for the data. The Cronbach's α coefficient of the scale was 0.910， with Cronbach's α coefficients of 0.835 and 0.912 for the perceived discrimination and perceived rejection， respectively. The split-half reliability of the scale was 0.803， and the test-retest reliability was 0.920. ConclusionThe Chinese version of CIRDS has excellent reliability and validity， which can be used to evaluate the perceived discrimination in maintenance hemodialysis patients.

MethodsA total of 72 DFU patients with damp-heat obstructing syndrome were randomly assigned to treatment group （36 cases） and the control group （36 cases）. Both groups received standard treatment and topical antibiotic bone cement for ulcer wounds， while the treatment group received oral Xiaozhong Zhitong Mixture （50 ml per time， three times daily） in additionally. Both groups underwent daily wound dressing changes for 21 consecutive days. Ulcer healing rate， serum levels of tumor necrosis factor-alpha （TNF-α）， interleukin-1 beta （IL-1β）， malondialdehyde （MDA）， superoxide dismutase （SOD）， C-reactive protein （CRP）， and white blood cell （WBC） count were observed before and after treatment， and visual analog scale （VAS） scores for wound pain， traditional Chinese medicine （TCM） syndrome scores， and the DFU Healing Scale （DMIST scale） were also compared. Liver and kidney function were evaluated before and after treatment， and adverse events such as allergic reactions， worsening ulcer pain were recorded. ResultsTotally 35 patients in the treatment group and 33 in the control group were included in the final analysis. The ulcer healing rate in the treatment group was （87.93±9.34）%， significantly higher than （81.82±12.02）% in the control group （P = 0.035）. Compared to pre-treatment levels， both groups showed significant reductions in serum CRP， WBC， MDA， IL-1β， and TNF-α levels， with an increase in SOD level （P＜0.05）. TCM syndrome scores， VAS， and DMIST scores also significantly decreased in both groups （P＜0.05）， with greater improvements in the treatment group （P＜0.05）. No significant adverse reactions were observed in either group during treatment. ConclusionXiaozhong Zhitong Mixture combined with antibiotic bone cement has significant advantages in promoting DFU healing， reducing inflammatory response， and alleviating oxidative stress in DFU patients with damp-heat obstructing syndrome， with good safety for DFU patients with damp-heat obstructing syndrome.

BACKGROUND:Lijin manipulation can promote skeletal muscle repair and treat skeletal muscle injury.However,the formation of fibrosis and scar tissue hyperplasia are closely related to the quality of skeletal muscle repair.To study the regulatory effect of Lijin manipulation on the formation of fibrosis and scar tissue hyperplasia is helpful to explain the related mechanism of Lijin manipulation to improve the repair quality of skeletal muscle injury. OBJECTIVE:To explore the mechanism of Lijin manipulation to improve the repair quality of skeletal muscle injury in rabbits,thereby providing a scientific basis for clinical treatment. METHODS:Forty-five healthy adult Japanese large-ear white rabbits were randomly divided into blank group,model group and Lijin group,with 15 rats in each group.Gastrocnemius strike modeling was performed in both model group and Lijin group.The Lijin group began to intervene with tendon manipulation on the 3rd day after modeling,once a day,and 15 minutes at a time.Five animals in each group were killed on the 7th,14th and 21st days after modeling.The morphology and inflammatory cell count of gastrocnemius were observed by hematoxylin-eosin staining,the collagen fiber amount was observed by Masson staining,the expression of interleukin-6 and interleukin-10 in gastrocnemius was detected by ELISA.The protein and mRNA expressions of paired cassette gene 7,myogenic differentiation factor,myoblastogenin,alpha-actin,transforming growth factor beta 1,and type Ⅰ collagen were detected by western blot and RT-PCR,respectively,and the expression of type Ⅰ collagen protein was detected by immunohistochemistry. RESULTS AND CONCLUSION:Hematoxylin-eosin staining and Masson staining showed that compared with the model group,inflammatory cell infiltration and collagen fiber content decreased in the Lijin group(P<0.01),and the muscle fibers gradually healed.ELISA results showed that compared with the model group,the expression of interleukin-6 in the Lijin group continued to decrease(P<0.05),and the expression of interleukin-10 increased on the 7th day after modeling(P<0.05)and then showed a decreasing trend(P<0.05).Western blot and RT-PCR results showed that compared with the model group,the protein and mRNA expressions of paired cassette gene 7,myogenic differentiation factor,myoblastogenin in the Lijin group were significantly increased on the 14th day after modeling(P<0.05),but decreased on the 21st day(P<0.05);the protein and mRNA expressions of alpha-actin,transforming growth factor beta 1,and type Ⅰ collagen in the Lijin group were significantly decreased compared with those in the model group(P<0.05).Immunohistochemical results showed that the expression of type Ⅰ collagen in the Lijin group was significantly lower than that in the model group(P<0.05).To conclude,Lijin manipulation could improve the repair quality of skeletal muscle injury by inhibiting inflammation,promoting the proliferation and differentiation of muscle satellite cells,and reducing fibrosis.

Objective To establish a chronic rejection (CR) model of mouse heart transplantation and analyze its characteristics. Methods Allogeneic BALB/c and C57BL/6 mice were used as donor and recipient for heart transplantation, and intraperitoneal injection of cytotoxic T lymphocyte-associated antigen 4-immunoglobulin (CTLA4-Ig) was given 1 and 2 days after surgery. Graft survival time, donor specific antibody (DSA) level, graft pathology and inflammatory cell infiltration were observed. Results In allogeneic transplantation model, graft survival time was prolonged after CTLA4-Ig treatment [(28.2±4.1) d vs. (7.0±0.7) d, P < 0.01]. The level of serum DSA-IgG increased at 2, 3 and 4 weeks after surgery, while the level of DSA-IgM remained unchanged. Myocardial cell injury, inflammatory cell infiltration, interstitial fibrosis and C4d deposition in capillaries were aggravated 3 weeks after operation and worsened 4 weeks after operation. The infiltrated immune cells were mainly macrophages, T cells and plasma cells. Conclusions Mouse allogeneic heart transplantation combined with CTLA4-Ig successfully establishes a CR model, which provides a basis for subsequent studies on the pathogenesis and intervention of CR.

OBJECTIVE To investigate the effects of Estradiol tablet/Estradiol and dydrogesterone tablet combined with Dan’e fukang decoction on postoperative recovery， sex hormone levels， uterine artery blood flow， and endometrium in patients with high risk of endometrial basal layer injury after induced abortion， and evaluate the safety of drug use. METHODS A retrospective analysis was conducted on the clinical data of 244 patients with high risk of endometrial basal layer injury who underwent artificial abortions in our hospital between January 2022 and December 2023. They were divided into control group （120 cases） and observation group （124 cases） according to postoperative medication plan. All patients received anti-infective treatment after induced abortion. Based on it， control group was given Estradiol tablet/Estradiol and dydrogesterone tablet， and observation group was given Estradiol tablet/Estradiol and dydrogesterone tablet+Dan’e fukang decoction， for consecutive 28 d. The time of vaginal bleeding， abdominal pain， return of menstruation， and vaginal bleeding volume were observed in 2 groups； serum sex hormone levels [serum follicle stimulating hormone （FSH）， luteinizing hormone （LH）， estradiol， and progesterone]， uterine artery blood flow parameters [peak systolic blood flow velocity （PSV）， pulsatility index （PI）， and resistance index （RI）] and endometrial thickness were compared between the two groups before and after treatment. The occurrence of complications and adverse reactions in patients were recorded. RESULTS After treatment， the duration of vaginal bleeding， vaginal bleeding volume， duration of abdominal pain， and menstrual cycle recovery time in observation group were significantly shorter or less than the control group （P＜0.05）. After treatment， both groups exhibited a significant increase in endometrial thickness， serum FSH and LH levels， and PSV， compared to before treatment， and the observation group was significantly thicker/higher than the control group （P＜0.05）； the levels of estradiol and progesterone， as well as the values of PI and RI， were significantly lower than those before treatment， and the observation group was significantly lower than the control group （P＜0.05）. The total incidence of postoperative complications in observation group was significantly lower than control group （P＜0.05）， but there was no significant difference in the total incidence of adverse reactions between the 2 groups （P＞0.05）. CONCLUSIONS Estradiol tablet/Estradiol and dydrogesterone tablet combined with Dan’e fukang decoction can accelerate the postoperative recovery of patients with high risk of endometrial basal layer injury after induced abortion， promote endometrial growth， regulate serum sex hormone levels， improve uterine artery blood flow， reduce postoperative complications， and have good safety.

Objective: To investigate the distribution characteristics of CD36 antigen in healthy individuals in Xinjiang, China and analyze the molecular mechanisms underlying CD36 deficiency. Methods: Flow cytometry was used to assess CD36 antigen expression on platelets from 881 healthy individuals who underwent physical examinations between June and August 2023. Differences in CD36 antigen distribution among ethnic groups were compared, and genotyping and third-generation sequencing were conducted on samples with CD36 deficiency. Results: Among the 881 samples, 4 cases (0.5%) of CD36 type Ⅱ deficiency were identified. The deficiency frequency was 0.7% (3/430) in Han individuals and 0.3% (1/363) in Uygur individuals, with no statistically significant difference between the two groups (P>0.05). No mutations were detected in the coding regions of the deficient samples. Two samples exhibited a (TG)11 in intron 3. Among the 12 linked mutation sites, g. 55589 G>A was mutated to g. 55589G Del, while g. 55593 A del did not occur; however, g. 55591A>T was observed nearby. Additionally, 52742insGAAAA was present in 100% of the (TG)11 haplotypes, potentially representing a novel linked mutation. Conclusion: This study indicates that the positive frequency of CD36 antigen in Xinjiang is relatively high, suggesting a low risk of alloimmune diseases in clinical practice. The (TG)11 in intron 3 is not universally present in all CD36 type Ⅱ deficiency cases, and the number of linked mutation sites extends beyond the previously reported 12.

Objective: To investigate the distribution characteristics of Kidd blood group antigens, phenotypes and genotypes in Xinjiang and their influence on the risk of coronary heart disease. Methods: Samples from 7 981 patients treated at People's Hospital of Xinjiang Uygur Autonomous Region from August 1, 2023 to May 31, 2024 were collected for Jk(a-b-) phenotype screening via urea hemolysis test, followed by the third-generation sequencing (TGS). Kidd blood group Jk and Jk antigens in 1 081 patients with coronary heart disease and 1 021 healthy people were detected, and their phenotype frequency distribution was analyzed and corresponding gene frequencies were calculated. Correlation analysis and logistic regression were used to evaluate the influence of Kidd blood group antigen expression on coronary heart disease risk. Results: Two Jk(a-b-) phenotype samples were detected, both resulting from novel gene mutation combinations. Comparative analysis of two groups revealed a higher proportion of the Jk(a-b+) phenotype in the case group (22.5%, 243/1 081) than in the control group (18.5%, 189/1 021). Moreover, Kidd blood group phenotype distribution varied significantly across all ethnic groups in the case group (P<0.05). In the control group, the Hui ethnic group exhibited the highest JK JK genotype frequency 64.15% (34/53). In the case group, the highest JK allele frequency was observed in Mongol ethnic group 56.31% (125/222), and the lowest in Han patients 45.71% (341/746). The expression of Jk antigen was negatively correlated with coronary heart disease (P<0.05). Conclusion: The distribution of Kidd blood group system varied across ethnic groups in Xinjiang. The expression of Jk antigen may have protective effect on coronary heart disease, which provides a basis for future clinical blood transfusion treatment and the mechanism study of the correlation between Kidd blood group and coronary heart disease.

Bronchial asthma （asthma） is a heterogeneous disease characterized by airflow limitation， airway remodeling， and recurrent symptoms such as wheezing， shortness of breath， chest tightness， and cough. Its prevalence is gradually increasing， and a portion of patients are still poorly controlled， leading to a serious social and medical burden. Modern studies have proposed the concept of the "lung-gut axis"， which is based on the crosstalk between microorganisms and their metabolites in the lungs and large intestine， and have indicated that microbial dysbiosis in these organs may affect the onset and progression of asthma. Traditional Chinese medicine （TCM） has found the phenomenon of lung-intestinal comorbidity and put forward the importance of "lung-intestinal coordination therapy" in the treatment of lung-related diseases. It has been found that intestinal flora and their metabolites can modulate immune responses through the lung-gut axis， demonstrating great potential for predicting asthma susceptibility， anticipating phenotypes， assessing asthma severity， and guiding treatment. TCM comopunds that embody lung-intestinal coordination therapy， including herbal formulas， single herbs， acupuncture， moxibustion， acupoint application， and spinal pinching therapy， has been shown to regulate intestinal flora， improve metabolism， regulate immunity， alleviate lung inflammation， reduce mucus secretion， inhibit airway remodeling， effectively alleviate symptoms， and delay lung function decline. Based on "lung-intestinal coordination therapy"， this paper used intestinal flora as the entry point to summarize the underlying mechanisms of TCM in asthma treatment and highlighted the pivotal role of intestinal flora in asthma， providing a new idea for its clinical treatment through the intestinal flora .

Objective To compare the cost-effectiveness between sodium valproate and levetiracetam in the treatment of childhood epilepsy and provide an economic basis for clinical medication choices. Methods A cost-effectiveness analysis was conducted using a decision tree model to compare the effectiveness and drug costs of sodium valproate and levetiracetam in treating childhood epilepsy. Single-factor sensitivity analysis and probabilistic sensitivity analysis were used to assess the impact of parameter variations on the study results. Results The treatment cost of levetiracetam was significantly higher than that of sodium valproate. The incremental cost-effectiveness ratio （ICER） of levetiracetam compared to sodium valproate was ¥8 628.43. Sensitivity analysis results were consistent with the base-case analysis. The probabilistic sensitivity analysis showed that, over a 6-month treatment period, levetiracetam became a more cost-effective option when the willingness-to-pay （WTP） threshold was ¥9,000 or higher. One-way sensitivity analysis revealed that the price of levetiracetam was the most influential factor affecting the ICER. Conclusion When the WTP per effective pediatric epilepsy case is ¥9,000 or higher, levetiracetam demonstrates a cost-effectiveness advantage.
