ObjectiveTaking classical herbal pair compatibility research as the entry point， this study aimed to deeply investigate the material basis and compatibility rules underlying the antidepressant effects of the traditional Chinese medicine （TCM） formula Zhizi Houpotang， and to elucidate its antidepressant mechanism， with a particular focus on its regulation of neuroinflammatory responses mediated by the NOD-like receptor protein 3 （NLRP3）/gasdermin D （GSDMD） signaling pathway and the consequent improvement of neuronal synaptic plasticity. MethodsC57BL/6J mice were randomly divided into a blank control group， a chronic unpredictable mild stress （CUMS） depression model group， a Zhizi Houpotang full-formula group （6 g·kg^-1·d^-1）， a Magnoliae Officinalis Cortex （MOC）-Aurantii Fructus Immaturus （AFI） herbal pair group （4.2 g·kg^-1·d^-1）， a Gardeniae Fructus （GF）-MOC herbal pair group （4.2 g·kg^-1·d^-1）， a GF-AFI herbal pair group （3.6 g·kg^-1·d^-1）， and a positive drug group （fluoxetine， 12 mg·kg^-1·d^-1）. Depressive-like behaviors in mice were evaluated using behavioral tests. Immunofluorescence staining was used to label and quantify the expression of the microglial marker ionized calcium-binding adaptor molecule 1 （Ibal） and the purinergic receptor P2X ligand-gated ion channel 7 （P2RX7） in the prefrontal cortex （PFC）. Enzyme-linked immunosorbent assay （ELISA） was applied to detect the levels of inflammatory cytokines interleukin-1β （IL-1β） and interleukin-18 （IL-18） in serum and PFC tissues. Western blot was employed to determine the expression of pannexin 1 （Panx1）， P2RX7， NLRP3， apoptosis-associated speck-like protein containing a CARD （ASC）， Caspase-1， GSDMD， postsynaptic density protein 95 （PSD95）， and the presynaptic protein Synapsin 1 in PFC tissues. Golgi staining was used to assess dendritic spine density of neurons in the PFC. ResultsCompared with the blank control group， the depression model group exhibited significant depressive-like behaviors. In addition， the immunofluorescence areas of Ibal and P2RX7 in the PFC were significantly increased （P<0.01）， the levels of IL-1β and IL-18 in serum and the PFC were significantly elevated （P<0.01）， and the protein expression levels of Panx1， P2RX7， NLRP3， ASC， Caspase-1， and GSDMD in the PFC were significantly upregulated （P<0.01）. In contrast， the protein expression levels of PSD95 and Synapsin 1 were significantly downregulated （P<0.01）， and neuronal dendritic spine density was significantly reduced （P<0.01）. Compared with the model group， the Zhizi Houpotang full-formula group and the GF-MOC herbal pair group showed significant improvement in all the above indicators （P<0.01）. The GF-AFI herbal pair group improved all the above indicators except P2RX7， Caspase-1， GSDMD， and PSD95 （P<0.05， P<0.01）. In contrast， the MOC-AFI herbal pair group showed no statistically significant improvement in any of the above indicators compared with the model group. ConclusionZhizi Houpotang and its key herbal pair， GF-MOC， can effectively ameliorate CUMS-induced depressive-like behaviors in mice. Its core antidepressant mechanism may involve inhibition of P2RX7/Panx1 signaling， thereby blocking the NLRP3/GSDMD-mediated pyroptosis pathway and significantly reducing the release of inflammatory cytokines IL-1β and IL-18. Simultaneously， it upregulates the expression of synapse-related proteins PSD95 and Synapsin 1 and increases dendritic spine density， promoting the recovery of synaptic plasticity. These results suggest that GF plays a key role in the antidepressant effects of this formula， and that the compatibility of GF with MOC may represent the principal herbal pair combination responsible for its core therapeutic action.

Objective:To explore the value of contrast enhanced ultrasonography(CEUS) combined with shear wave elastography (SWE) in the diagnosis of urethral stricture.Methods:One hundred and twenty patients with urethral stricture were recruited, and preoperative retrograde urography, common urethral ultrasound, and CEUS were used to measure the length of the stricture site, and SWE was used to detect the elasticity value of the stricture site and its nearby spongiosum. Intraoperative urethral stricture lesion site measurements were performed to confirm the actual lesion location and length during surgery and to compare them with the lengths measured in the preoperative examination;4 months after surgery, SWE was used to detect the stiffness of the surgical site and to assess the surgical efficacy and prognosis.Results:The stenosis length measured by CEUS and intraoperative measurement had no statistical difference: (4.41 ± 1.47) cm vs. (4.37 ± 1.36) cm, t = 0.22, P>0.05. The elastic value in urethra stenosis in SWE was higher than that in normal urethra: (33.1 ± 6.7) kPa vs. (23.3 ± 4.1) kPa, there was statistical difference ( t = 13.67, P<0.05). The elastic value of unobstructed urethra and that of normal urethra after reconstruction had no statistical difference ( t = 0.95, P>0.05). Conclusions:CEUS combined with SWE is a safe, accurate and effective method to evaluate urethral stricture. SWE can be used to measure postoperative outcomes and recurrence.

Objective:To evaluate the feasibility and safety of endoscopic retrograde cholangiopancreatography (ERCP) combined with peroral cholangioscopy in the treatment of gallbladder stones with common bile duct stones.Methods:Clinical data of 19 patients with gallbladder stones and common bile duct stones admitted to the Digestive Endoscopy Center, Jilin People’s Hospital from July 2019 to November 2024 were retrospectively analyzed, including 13 males and 6 females, aged (68.2±14.2) years. All patients underwent ERCP combined with peroral cholangioscopy. Perioperative data, including the long diameter of the common bile duct stone, the long diameter of the gallbladder stone, the number of stones, ERCP operative time, gallbladder stone extraction time, stone clearance status, hospitalization duration, and complications, were recorded. Postoperative follow-up was conducted through outpatient visits or telephone consultations to monitor recurrence.Results:The long diameter of the common bile duct stones was (9.55±2.86) mm, and the long diameter of the gallbladder stones was 4.0(3.0, 5.5) mm. Among the 19 patients, 5 had single gallbladder stones, and 14 had multiple stones. The ERCP operative time was (49.0±18.4) min, and the gallbladder stone extraction time was (25.0±11.7) min. The methods used for handling the gallbladder neck were as follows: two cases involved stone removal after 6 mm balloon dilation; six cases involved stone removal after metal stent placement; three cases involved the placement of a plastic stent in the gallbladder for three months, followed by stone extraction using ERCP combined with peroral cholangioscopy; eight cases were treated directly for stone removal without specific procedures. Among the 19 patients, 11 completed stone removal within one treatment, while eight required a second treatment. All patients had complete clearance of both common bile duct and gallbladder stones under direct peroral cholangioscopy. No severe complications occurred postoperatively, although two cases developed post-ERCP pancreatitis. The postoperative hospitalization time was 8.0 (6.0, 10.0) d. The follow-up duration for the 19 patients was 14.0 (8.5, 20.0) months. One patient had a recurrence of gallbladder stones 12 months postoperatively, while no other patients had recurrence at the final follow-up.Conclusion:ERCP combined with peroral cholangioscopy is a safe and feasible approach for treating gallbladder stones with common bile duct stones.

Objective:To explore the effect of Lactobacillus reuteri on testicular injury in mice exposed to neonicotinoid insec-ticides(NNI).Methods:Fifteen C57BL/6 male mice were randomly divided into control group(CTRI.group),exposure group(NNI group)and Lactobacillus intervention group(NNI-L group).The mice in CTRL group were given 0.02ml/g of 0.5％carboxym-ethyl cellulose sodium solution by gavage for 14 days.The mice in NNI group were given 0.02 ml/g of NNI mixture by gavage for 14 days.The mice in NNI-L group were given 0.02 ml/g of NNI mixture by gavage and 5 × 108cfu/ml of Lactobacillus reuteri powder so-lution for 14 days.Then,the histomorphology and function of testicle were evaluated by hematoxylin-eosin staining,immunofluores-cence staining and RNA sequencing.Results:Compared with CTRL group,the thickness of testicular seminiferous epithelium in the NNI group was significantly thinner.And the decline in the number of spermatogenic cells and sperm was observed.And the expression of spermatogonial stem cell marker UCHL1 was down-regulated which was significantly improved in NNI-L group compared with the NNI group.The abnormal expressions of hormone and sperm methylation related genes in testis of NNI group were detected by RNA sequen-cing,with significant down-regulation being found in NPFF and IGF2.While the expression of HSD3B8 was significantly up-regulated.The abnormal expression of these genes could be significantly improved after oral administration of Lactobacillus reuteri.Conclusion:Testicular spermatogenesis and endocrine function can be damaged by NNI exposure.And oral administration of Lactoba-cillus reuteri protects testis from the adverse effects of NNI toxicity.

Objective To explore the diagnostic value of exhaled volatile organic compounds (VOCs) for cystic fibrosis (CF). Methods A systematic search was conducted in PubMed, EMbase, Web of Science, Cochrane Library, CNKI, Wanfang, VIP, and SinoMed databases up to August 7, 2024. Studies that met the inclusion criteria were selected for data extraction and quality assessment. The quality of included studies was assessed by the Newcastle-Ottawa Scale (NOS), and the risk of bias and applicability of included prediction model studies were assessed by the prediction model risk of bias assessment tool (PROBAST). Results A total of 10 studies were included, among which 5 studies only identified specific exhaled VOCs in CF patients, and another 5 developed 7 CF risk prediction models based on the identification of VOCs in CF. The included studies reported a total of 75 exhaled VOCs, most of which belonged to the categories of acylcarnitines, aldehydes, acids, and esters. Most models (n=6, 85.7%) only included exhaled VOCs as predictive factors, and only one model included factors other than VOCs, including forced expiratory flow at 75% of forced vital capacity (FEF75) and modified Medical Research Council scale for the assessment of dyspnea (mMRC). The accuracy of the models ranged from 77% to 100%, and the area under the receiver operating characteristic curve ranged from 0.771 to 0.988. None of the included studies provided information on the calibration of the models. The results of the Prediction Model Risk of Bias Assessment Tool (PROBAST) showed that the overall bias risk of all predictive model studies was high, and the overall applicability was unclear. Conclusion The exhaled VOCs reported in the included studies showed significant heterogeneity, and more research is needed to explore specific compounds for CF. In addition, risk prediction models based on exhaled VOCs have certain value in the diagnosis of CF, but the overall bias risk is relatively high and needs further optimization from aspects such as model construction and validation.

Objective To explore the correlation of bilateral knee joint strength asymmetry with balance,walking ability,and motor function in hemiplegic stroke patients,providing a reference for clinical assessment of stroke patients.Methods A total of 46 hemiplegic stroke patients admitted to the Rehabilitation Medicine Department of People's Hospital of Shijiazhuang from February to December 2023 were selected.According to the Berg Balance Scale(BBS)scores,patients were divided into Group A(BBS score≤20,n=23)and Group B(BBS score>20,n=23).The peak torque and differences of bilateral knee flexors and extensors were compared between two groups.Isokinetic technology was used to assess the differences in peak torque of bilateral knee joints at 60°/s and 120°/s.BBS,Functional Ambulation Classification(FAC),and Fugl-Meyer Assessment of Lower Extremity(FMA-LE)were used to evaluate patients'balance,walking ability,and lower limb motor function.The correlation between bilateral knee joint peak torque and its difference with the scores of three functional scales was analyzed.Results The peak torque of knee flexors and extensors at 60°/s in group A was significantly lower than that in group B(P<0.05).At both 60°/s and 120°/s the differences in peak torque between the healthy and affected sides of knee flexors and extensors were greater than those in group B(P<0.05).At 60°/s,the difference in peak torque of bilateral knee extensors in hemiplegic stroke patients was negatively correlated with the scores of BBS,FAC,and FMA-LE(r=-0.569,-0.582,-0.606,P<0.01),as did the knee flexors(r=-0.534,-0.386,-0.458,P<0.05).At 120°/s,similar negative correlations were observed for both knee extensors(r=-0.304,-0.304,-0.443,P<0.05)and flexors(r=-0.337,-0.349,-0.370,P<0.05).Conclusions Bilateral knee joint strength asymmetry in hemiplegic stroke patients is negatively correlated with balance and walking ability.The difference in strength between the two sides of knee joint may be one of the clinical indicators for evaluating the motor function of stroke patients.

Objective To explore the effects of Emotional Freedom Techniques combined with PERMA model intervention on fear of disease progression and quality of life in postoperative liver cancer patients.Methods A total of 58 liver cancer patients admitted from September 2023 to February 2024 were randomly divided into the experimental group(n=29)and the control group(n=29)using a random number table method.The experimental group received Emotional Freedom Techniques combined with PERMA-based positive psychological intervention,while the control group received the holistic nursing and routine psychological guidance.Both groups underwent the continuous intervention for 8 weeks.Outcomes were assessed using the Fear of Progression Questionnaire-Short Form(FoP-Q-SF),Distress Thermometer(DT),Self-Rating Anxiety Scale(SAS),Self-Rating Depression Scale(SDS),Cancer Fatigue Scale(CFS),Athens Insomnia Scale(AIS)and Index of Well-Being(IWB).Results After the intervention,the experimental group showed the significantly lower scores than those in the control group in FoP-Q-SF(24.97±2.34/34.10±8.46),DT(2.24±0.95/2.93±1.33),SAS(49.55±1.35/58.55±4.60),SDS(51.86±1.58/61.79±4.00),CFS(4.03±0.94/5.10±1.18),and AIS(2.45±1.12/4.07±0.96)(all P<0.05),while the IWB score(10.56±1.74/7.39±2.05)was significantly higher than that in the control group(P<0.05).Conclusion The combination of Emotional Freedom Techniques and PERMA model intervention can effectively alleviate the disease-related fears,improve the negative emotions,reduce the physical symptoms and enhance the subjective well-being in postoperative liver cancer patients,and it has a significant clinical application value.

Objective To analyze the imaging features of cerebral small vessel disease in patients with type 2 diabetes mellitus by multimodal MRI.Methods The clinical data of 160 patients with cerebral small vessel disease admitted to our hospital from January to December 2020 were retrospectively analyzed.According to whether they were complicated with type 2 diabetes mellitus,they were divided into the diabetic group and the non-diabetic group,with 80 cases in each group.Both groups underwent multimodal MRI scans.And the severity of lacunar infarction,the severity of subcortical and periventricular white matter lesions,white matter integral and cerebral microbleeds of patients in the two groups were compared.Results The severity of lacunar infarction(χ2=34.076,P=0.001),subcortical white matter lesions(χ2=25.000,P=0.001),periventricular white matter lesions(χ2=22.895,P=0.001)and white matter integral(t=12.370,P=0.001)of patients in the diabetic group were significantly higher than those in the non-diabetic group.No cerebral microbleeds were detected in either group of patients.Conclusion Patients with cerebral small vessel disease and type 2 diabetes mellitus show characteristic multimodal MRI changes.The increase in the number of lacunar infarction lesions and the aggravation of white matter lesions can be used as the characteristic imaging basis for the diagnosis of type 2 diabetes mellitus related cerebral small vessel disease.

Osteoarthritis(OA)is a common joint disease in clinical practice,and cartilage damage is a typical pathological change.The pathogenesis of OA is complex,and various adverse factors can lead to the occurrence of OA.Mitochondria are im-portant organelles within cells and play important roles in cellular physiological and pathological activ-ities.Mitochondrial quality control is an important regulatory mechanism in the body to maintain nor-mal mitochondrial structure and function,mainly including mitochondrial biogenesis,mitochondrial dynamics,mitochondrial autophagy,mitochondrial oxidative stress,and other forms.The imbalance of mitochondrial quality control in chondrocytes is closely related to the occurrence and development of osteoarthritis,and regulating the balance of mi-tochondrial quality control is a potential therapeu-tic point for osteoarthritis.The author reviewed rel-evant research literature in recent years to provide a review of the relationship between mitochondrial quality control and the occurrence and develop-ment of osteoarthritis,in order to provide new ideas and directions for the research and diagnosis and treatment strategies of osteoarthritis.
