Objective: To explore the relationship between non suicidal self injury (NSSI) behavior and serum lipid levels as well as thyroid function among college students with depression. Methods: A total of 169 college students with depression in the psychiatry departments of tertiary hospitals (grade 3A and 3B) in Ningbo from December 2023 to April 2025 were selected. The Adolescent Self injury Scale (ASIS) was used to assess the presence of NSSI, and participants were accordingly divided into a NSSI group ( n =51) and a non NSSI group ( n =118). General demographic data (including gender, age, and family situation) were collected from both groups. Blood tests were performed to measure lipid profiles [triglyceride (TG), total cholesterol (TC), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C)] and thyroid hormones [triiodothyronine (T3), thyroxine (T4), free triiodothyronine (FT3), free thyroxine (FT4), thyroid stimulating hormone (TSH)]. Multivariate Logistic regression was employed to analyze risk factors for NSSI, and receiver operating characteristic (ROC) curve analysis was used to evaluate the predictive value of serum lipid and thyroid hormone levels for NSSI occurrence in college students with depression. Results: The levels of TC, LDL-C, and TSH in the NSSI group were (4.02±0.73) mmol/L, (2.32±0.36) mmol/L, and (6.57±1.95) mU/L , which were significantly higher than those in the non NSSI group [(3.41±0.56) mmol/L, (2.00±0.27) mmol/L, and ( 4.48± 1.09) mU/L, respectively] ( t =5.32, 5.60, 7.20, all P <0.05). Logistic regression analysis revealed that college students from single parent/reconstituted families, those who had experienced school bullying, and those with higher levels of TC, LDL-C, and TSH had a significantly increased risk of engaging in NSSI ( OR =5.22, 6.12, 5.90, 83.64, 3.64, all P <0.05). ROC curve analysis demonstrated that the combined detection of TC, LDL-C, and TSH had high diagnostic efficacy for predicting NSSI in college students with depression, with a sensitivity of 86.3% and a specificity of 94.9%. Conclusions NSSI behavior in college students with depression is associated with serum lipid levels and thyroid function. These biomarkers may serve as useful reference indicators for assessing the conditions of these patients.

ObjectiveThis study aimed to investigate whether Bushen Tongluo prescription inhibits macrophage polarization by regulating the Wnt3a/β-catenin signaling pathway， thereby reducing epithelial-mesenchymal transition and excessive extracellular matrix deposition， in order to elucidate the anti-pulmonary fibrosis mechanisms of Bushen Tongluo prescription and provide a new theoretical basis for the clinical treatment of pulmonary fibrosis. MethodsFifty male Sprague-Dawley （SD） rats were randomly divided into a blank group， model group， pirfenidone group， and high- and low-dose Bushen Tongluo prescription groups. Except for the blank group， the pulmonary fibrosis model was established by intratracheal instillation of bleomycin. Intervention was initiated on day 28 after modeling. The high- and low-dose Bushen Tongluo prescription groups were administered Bushen Tongluo prescription at doses of 30.88， 15.44 g·kg^-1， respectively， by intragastric gavage. The pirfenidone group was administered pirfenidone capsules at 110 mg·kg^-1 by intragastric gavage. The blank and model groups were given an equal volume of normal saline by gavage， once daily for 90 days. After treatment， the level of transforming growth factor-β₁ （TGF-β₁） in bronchoalveolar lavage fluid （BALF） was detected by enzyme-linked immunosorbent assay （ELISA）. Morphological changes in lung tissue and the collagen volume fraction were compared. The protein distribution and expression of E-cadherin， cytokeratin 19， α-smooth muscle actin （α-SMA）， vimentin， collagen type Ⅰ （Col Ⅰ）， and collagen type Ⅲ （Col Ⅲ） in lung tissue were detected by immunohistochemistry. The protein distribution and expression of CD68， arginase-1 （Arg-1）， inducible nitric oxide synthase （iNOS）， Wnt3a， and β-catenin in lung tissue were detected by immunofluorescence. The protein expression of Wnt3a and β-catenin in lung tissue was detected by Western blot， and the mRNA expression of Wnt3a and β-catenin was detected by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultsCompared with the blank group， a large number of inflammatory cells infiltrated the airway walls， alveolar spaces， and interstitial tissue in the model group， with obvious fibrous tissue hyperplasia. The level of TGF-β₁ in BALF was significantly increased. The protein expression of E-cadherin and cytokeratin 19 in lung tissue was decreased， whereas the protein expression of α-SMA， Vimentin， Wnt3a， β-catenin， Col Ⅰ， and Col Ⅲ was increased. The fluorescence-positive area ratios of CD68， Arg-1， iNOS， Wnt3a， and β-catenin in lung tissue were increased. The protein and mRNA expression levels of Wnt3a and β-catenin in lung tissue were significantly increased （P<0.01）. Compared with the model group， all treatment groups showed varying degrees of improvement in inflammatory cell infiltration and fibrous tissue hyperplasia in the airway walls， alveolar spaces， and interstitial tissue， decreased TGF-β₁ levels in BALF， increased protein expression of E-cadherin and cytokeratin 19 in lung tissue， decreased protein expression of α-SMA， Vimentin， Col Ⅰ， and Col Ⅲ， decreased fluorescence-positive area ratios of CD68， Arg-1， iNOS， Wnt3a， and β-catenin in lung tissue， and decreased protein and mRNA expression levels of Wnt3a and β-catenin in lung tissue （P<0.05， P<0.01）. ConclusionBushen Tongluo prescription can improve bleomycin-induced pulmonary fibrosis in rats by inhibiting epithelial-mesenchymal transition and reducing excessive extracellular matrix deposition. The mechanism may be related to inhibition of the Wnt3a/β-catenin signaling pathway and the macrophage polarization mediated by this pathway.

Objective To use chromosome microarray analysis(CMA)technology to detect and analyze spontaneous abortion tissues,and explore the genetic factors that contribute to the occurrence of spontaneous abortion.Methods The abortion tissues of totally 1 038 patients with spontaneous abortion who came to the hospital for treatment from January 1,2019 to December 31,2021 were collected.CMA technology was used to detect the tissues,and the results were analyzed for genetic etiology.Results Among 1 038 cases of spontane-ous abortion patients,901 cases were qualified for sampling and 901 cases were actually tested.There were 443 cases of chromosomal abnormalities and(or)copy number variations(CNV)with unknown significance de-tected by CMA,with an abnormality rate of 49.17％.There were 41 cases of pathogenic CNV,accounting for 9.26％of the total abnormalities.There were statistically significant differences in the total chromosome ab-normality rate(x2=17.37)and chromosome number abnormality rate(x2=26.43)of aborted fetuses among different age groups of pregnant women(P＜0.001).There were statistically significant differences in the to-tal chromosome abnormality rate(x2=19.63)and chromosome number abnormality rate(x2=22.66)of dif-ferent miscarriage tissues during pregnancy(P＜0.001).Conclusion The application of CMA technology to detect the miscarriage tissue of patients with spontaneous abortion can improve the detection rate of chromo-somal abnormalities in miscarriage embryos,discover potential genetic factors,and provide genetic guidance for patients' next pregnancy.

TCM believes that the main pathogenesis of gastrointestinal dysfunction (GD) after laparoscopic cholecystectomy (LC) is spleen and stomach weakness, liver and stomach disharmony, liver depression and spleen deficiency, and intestinal depression. Moxibustion in the treatment of GD after LC can avoid the aggravation of gastrointestinal burden caused by oral drugs. The intervention methods mainly include suspension moxibustion, umbilical moxibustion, heat sensitive moxibustion, thunder fire moxibustion, warm acupuncture, partition moxibustion, etc. Moxibustion is often performed on the acupoints in liver meridian, spleen meridian, stomach meridian, small intestine meridian, large intestine meridian and Conception Vessel, such as Taichong (LR3), Ganshu (BL18), Yinlingquan (SP9), Zusanli (ST36), Tianshu (ST25), Wangu (SI4), Hegu (LI4), Zhongwan (CV12), Shenque (CV8) and Qihai (CV6). At present, most studies combined with moxibustion on the basis of conventional Western medicine treatment can significantly improve the efficacy, and have certain advantages in improving gastrointestinal motility decline, intestinal flora imbalance, first exhaust time, gastrointestinal hormone level disorder and intestinal mucosal barrier dysfunction. However, there are still some problems in the existing research: small sample size of clinical research, not perfect scoring scale, not unified treatment plan and operation standard, relatively scarce basic research, relatively simple acupoint research, lack of biochemical evaluation indicators, and the research of national moxibustion needs to be explored and improved in the future.

Pulmonary sarcoidosis is an immune system disease with an unclear etiology. Guided by the yang-reinforcing method， it is believed that the fundamental pathogenesis of pulmonary sarcoidosis lies in the disharmony between water and fire and the reckless movement of the ministerial fire. The failure of the spleen and stomach to maintain warmth， leading to the production of phlegm and blood stasis， is an important pathogenesis. The invasion of external pathogenic toxins， deeply penetrating into the interior， is considered a triggering factor for the disease. The treatment focuses on supplementing the yang， consolidating the kidney， drawing fire back to its source， warming the yang， benefiting the kidney， and nourishing the spleen to generate metal. It also emphasizes unblocking the yang， transforming turbidity， and eliminating phlegm and blood stasis.

Refractory chronic cough belongs to the category of "refractory cough" in traditional Chinese medicine， and it is believed that the root cause of intractable chronic cough is wind lodging in the spleen collaterals， with poor spleen yang and deficient kidney essence as the pathologic basis of the disease， which is present throughout the disease. The method advocated is to search the spleen collaterals and eliminate latent wind， warm the spleen yang and smooth the middle jiao， cultivate the kidney essence and consolidate the root， prescribed with modified Fuzi Lizhong Decoction （附子理中汤） plus Erxian Decoction （二仙汤） as the basis. The Fuzi Lizhong Decoction can warm yang and fortify the middle， and smooth the middle jiao， and the Erxian Decoction can cultivate the kidney essence and consolidate the innate. The two prescriptions could combine with Suye （Perilla frutescens）， Jingjie （Dysphania ambrosioides）， Fangfeng （Carum carvi） and other medicinals of cleaning characteristic， or combine with Gouteng （Uncaria rhynchophylla）， Chuanshanlong （Dioscorea nipponica）， Dilong （Kummerowia striata） and other medicinals of worm or cane category， to find the wind and expel pathogen， smooth spleen collaterals.

This article is based on ZHANG Jingyue's theory of yin-yang holism to explore the etiology， pathogenesis， and treatment of acute exacerbation of rheumatoid arthritis-associated interstitial lung disease （RA-ILD）. It is believed that the foundation of acute exacerbation of RA-ILD lies in real yin insufficiency and yin fail to control yang； external pathogen attacking is a common cause of acute exacerbation of RA-ILD. For treatment， it is important to first suppress ministerial fire by prescribing modified Yinhuo Decoction （引火汤）； if ministerial fire submerged， focus should be on nourishing both yin and yang； if real yin deficiency is the main issue， modified Zuogui Pill （左归丸） should be used； if real yang deficiency is prominent as well， modified Yougui Pill （右归丸） can be chosen. When yin and yang balanced， the disease could be solved.

Objective To investigate the value of anti-Müllerian hormone(AMH)in serum and cervical mucus,matrix metalloproteinases(MMPs)/tisszle inhibitor of metalloproteinase(TIMPs)combined with transvaginal ultrasound in evaluating ovarian reserve function in women preparing for a second child.Methods A total of 76 women who underwent pre-pregnancy examination and second pregnancy preparation in the Dongguan Shijie Hospital from November 2021 to September 2022 were included in the study.All the subjects underwent transvaginal ultrasound examination,and they were divided into normal group(n=32,normal ovarian function,antral follicle count≥5)and low group(n=44,ovarian hypofunction,antral follicle count<5)according to the number of sinus follicles.The transvaginal ultrasound parameters,AMH in serum and cervical mucus,and MMPs/TIMPs were compared between the two groups.Pearson linear correlation was used to analyze the relationships between ultrasound parameters,AMH in serum and cervical mucus,MMPs/TIMPs and antral follicle count.The receiver operating characteristic(ROC)curve was used to analyze the diagnostic efficacies of transvaginal ultrasound parameters,AMH in serum and cervical mucus,MMP/TIMP alone and their combination for ovarian hypofunction.Results The endometrial thickness and ovarian volume of the low group were(3.83±1.17)mm and(5.59±1.34)cm3,respectively,which were lower than those of the normal group([4.54±1.52]mm,[7.62±2.41]cm3,both P<0.05).Serum AMH level in the low group was lower than that in the normal group([2.11±0.65]ng/ml vs[4.65±3.78]ng/ml,P<0.05).There was no significant difference in the cervical mucus AMH between the two groups(both[0.08±0.02]ng/ml,P>0.05).The MMPs/TIMPs in serum and cervical mucus of the low group were 1.19±0.65 and 1.34±0.32,which were higher than those of the normal group(1.07±0.09 and 1.10±0.27,both P<0.05).Pearson correlation analysis showed that antral follicle count was positively correlated with endometrial thickness,ovarian volume and serum AMH level,and was negatively correlated with MMPs/TIMPs in serum and cervical mucus(all P<0.05).ROC curve analysis showed that the area under the curve of the combination of transvaginal ultrasound parameters,serum AMH,serum and cervical mucus MMPs/TIMPs in the diagnosis of ovarian dysfunction was 0.869,which was higher than that of each index alone(all P<0.05).Conclusion The combined application of serum AMH,serum and cervical mucus MMPs/TIMPs and transvaginal ultrasound is of great value in the evaluation of ovarian reserve function in women preparing for a second child.
