Major depressive disorder (MDD) is a prevalent psychiatric condition characterized by high rates of prevalence and recurrence. Repetitive transcranial magnetic stimulation (rTMS) has been widely utilized in the acute phase treatment of MDD and has shown potential in maintenance therapy. However, the factors influencing the efficacy of rTMS during the acute phase and the sustainability of its long-term therapeutic effects remain incompletely understood. Additionally, a consensus on the optimal maintenance treatment protocol has yet to be established. This article reviews recent evidence on the application of rTMS in both acute and maintenance treatment of MDD, aiming to summarize current research progress and provide insights for the further promotion and application of rTMS in clinical practice.

ObjectiveTo investigate the protective effects and mechanisms of Bushen Zhuyun prescription （BSZY） on abortion rats with kidney deficiency-corpus luteum inhibition syndrome. MethodsAn abortion rat model with kidney deficiency-corpus luteum inhibition syndrome was constructed. Pregnant mice aged 8-10 weeks were randomly divided into a control group （Control）， a model group （Model）， low-dose BSZY （BSZY-L）， medium-dose BSZY （BSZY-M）， and high-dose BSZY （BSZY-H） groups （2.57， 5.14， 10.28 g·kg^-¹）， and a Zishen Yutai Pill （ZSYT） group （1.575 g·kg^-¹）. Hematoxylin-eosin （HE） staining was used to evaluate histopathological changes in ovarian and decidual tissue of rats in each group. Enzyme-linked immunosorbent assay （ELISA） was employed to measure levels of estrogen （E₂）， progesterone （P）， luteinizing hormone （LH）， prolactin （PRL）， and follicle-stimulating hormone （FSH） in serum. The candidate targets of BSZY were obtained from the Traditional Chinese Medicine System Pharmacology Platform （TCMSP） and Integrative Pharmacology-based Research Platform of Traditional Chinese Medicine （TCMIP） v2.0 databases， while disease targets for recurrent spontaneous abortion （RSA） were retrieved from GeneCards， DrugBank， Online Mendelian Inheritance in Man （OMIM）， and Therapeutic Target Database （TTD）. The intersection targets were identified by the Venny 2.1.0 platform. Pathway enrichment analysis was conducted based on the Metascape database to predict the potential mechanisms of BSZY. Additionally. Western blot was used to verify the effects of BSZY on the expression of estrogen receptor （ERα）， phosphatidylinositol 3-kinase （PI3K）， and protein kinase B （Akt） and explore its protective mechanism on RSA rats. ResultsCompared with the control group， the model group exhibited significantly decreased uterine， ovarian， and embryonic wet weights （P<0.05， P<0.01）， with an abortion rate of 57.18%. The ovarian tissue showed varying degrees of reduction in primordial follicles， primary follicles， mature follicles， and corpora lutea， along with a large number of atretic follicles. The endometrium was thinner， and decidual tissue exhibited cellular edema and disorganized arrangement. In contrast， compared with the model group， the BSZY groups at all doses and the ZSYT group demonstrated increased uterine， ovarian， and embryonic wet weights， along with a reduced abortion rate. The number of primordial follicles， primary follicles， mature follicles， and corpora lutea increased， while atretic follicles decreased. The endometrium thickened， and decidual tissue displayed normal cellular structure with tight arrangement. Additionally， the model group showed significantly decreased levels of E₂， P， PRL， and FSH in serum （P<0.05， P<0.01）， along with a decreasing trend in LH level. In contrast， the BSZY groups at all doses exhibited significantly elevated levels of E₂， P， LH， PRL， and FSH in serum （P<0.05， P<0.01）. Network pharmacology predictions suggested that BSZY may exert protective effects against abortion in rats by activating the ERα/PI3K/Akt signaling pathway. Western blot results confirmed that BSZY significantly upregulated the expression of ERα， PI3K， and p-Akt proteins （P<0.05， P<0.01）. ConclusionBSZY has a protective effect on the abortion rats with kidney deficiency-corpus luteum inhibition syndrome， possibly by activating the ERα/PI3K/Akt signaling pathway to reduce ovarian apoptosis and regulate endocrine function， thereby lowering the abortion rate.

Objectives:To investigate the association between normal-weight central obesity with new-onset cardiovascular disease and all-cause mortality risk. Methods:A prospective cohort study was conducted,selecting a total of 93885 participants from the Kailuan Study who had their first physical examination in 2006-2007.According to waist circumference (central obesity:male waist circumference ≥90 cm,female waist circumference ≥85 cm;no central obesity:male waist circumference<90 cm,female waist circumference<85 cm) and body mass index (BMI,normal weight:18.5 kg/m2≤BMI<24.0 kg/m2;overweight/obesity:BMI ≥24.0 kg/m2),the participants were divided into 4 groups:normal weight no central obesity group (G1 group),normal weight central obesity group (G2 group),overweight/obesity no central obesity group (G3 group) and overweight/central obesity group (G4 group);Using the Kaplan-Meier method,the cumulative incidence of new-onset cardiovascular diseases (including hemorrhagic stroke,ischemic stroke and myocardial infarction) and all-cause mortality in different groups was calculated,and the Log-rank test was used for intergroup comparisons.Furthermore,the associations between the different groups and the risk of new-onset cardiovascular diseases and all-cause mortality were analyzed using the multivariate Cox proportional hazard regression model. Results:After a median follow-up of 14.97 (14.55,15.17) years,the cumulative incidence of new-onset cardiovascular diseases in G1 group,G2 group,G3 group and G4 group was 7.62％,10.84％,8.67％,12.91％ respectively (log-rank P<0.05) and the cumulative incidence of all-cause mortality was 12.83％,19.72％,10.65％,16.33％ respectively (log-rank P<0.01).After adjusting for confounding factors,Cox regression analysis showed that the HR (95％CI) of new-onset cardiovascular diseases in G2 group,G3 group and G4 group were 1.14 (1.04-1.25),1.07 (1.01-1.14),1.27 (1.21-1.34),respectively compared with G1 group (all P<0.05).The HR (95％CI) of all-cause mortality were 1.06 (1.00-1.14),0.90 (0.85-0.95),0.97 (0.93-1.01) compared with G1 group,and P values were 0.07,<0.01,0.15,respectively.The results of sensitivity analysis were consistent with the above major studies after excluding overweight/obesity and cancer participants during follow-up. Conclusions:Normal-weight central obesity increases the risk of new-onset cardiovascular diseases and all-cause mortality.

Objective:To explore the strategy of how to select an effective flap for reconstruction of the surgical defect in clavicular region after resection of malignant tumour and care for the aesthetic appearance of the flap donor site.Methods:A retrospective observational study was conducted. Twenty-three patients with soft tissue malignant tumour in clavicle region were treated, from March 2017 to April 2023, in the Department of Burn and Plastic Surgery of Changde Hospital, Xiangya School of Medicine, Central South University (the First People’s Hospital of Changde). The patients were 13 males and 10 females, aged 21 to 72 years old. Ten patients were of dermatofibrosarcoma protuberans, 6 of fibrosarcoma, 3 of squamous cell carcinoma of skin, 3 of undifferentiated pleomorphic sarcoma and 1 of mucinous adenocarcinoma. Nine patients had the first surgery and 14 were with tumour recurrence and had previousely received one or more surgery in other hospitals. The tumour size ranged from 2.0 cm×4.5 cm×1.0 cm to 10.0 cm×16.0 cm×3.0 cm. After radical resection, the sizes of surgical defect ranged from 9.0 cm×12.0 cm to 16.0 cm×22.0 cm. All the clavicular soft tissue malignancies had radical resection, and the secondary surgical defects were further modified to reduce the short and long dimensions of the defects. Flaps were selected according to the short dimension, depth and skin elasticity of the flap donor site. Of the 23 patients, 3 were treated with free inguinal flaps, 9 with ipsilateral pedicled latissimus dorsi flaps or thoracodorsal artery perforator flaps, 5 with free deep inferior epigastric artery perforator flap (DIEPF), 5 with free anterolateral thigh flap (ALTF) and 1 with free rectus abdominis flap. The modified defects sized 5.0 cm × 11.0 cm-12.0 cm×19.0 cm after the suture of margin and base of the defects (defects were reduced and modified). The flap sizes were 7.0 cm×13.0 cm-14.0 cm×23.0 cm. After surgery, the wound healing was observed through the visits of outpatient clinic, and telephone and WeChat interviews. According to the nature of the tumours, the patients were regularly reviewed at outpatient clinic to determine the local recurrence and metastasis of the tumour.Results:One pedicled latissimus dorsi myocutaneous flap was found with a greater tension after surgery. After partial removal of sutures and dressing changes, the secondary suture was performed 1 week later and the wound healed smoothly. A postoperative venous crisis was discovered in a free ALTF. It was monitored and re-anastomosed within 24 hours after surgery, and the flap survived and the wound healed smoothly. Otherwise, the rest of flaps achieved good blood supply and the wounds at the recipient and donor sites healed in one stage. In the postoperative follow-up, all flaps in the clavicular region were found good in appearance with no obvious swelling, and the donor sites healed well without scar contracture or dysfunction. One patient with a squamous cell carcinoma died of lung metastasis at 13 months after surgery. The rest of patients were found no tumour recurrence and had completed postoperative follow-up.Conclusion:After radical resection of malignant soft tissue tumours in the clavicular region, appropriate flaps were selected according to the size (short diameter) and depth of the modified defects, as well as the skin elasticity and relaxation of the flap donor site, hence to facilitate the direct suture of the flap donor site. It not only effectively reconstructs the surgical defect in clavicular region, but also minimises the damage to the flap donor site and achieves an aesthetic appearance at the flap donor site.

Objective:To explore the repair methods and effects of refractory wounds in patients after spinal internal fixation operation .Methods:The study was a retrospective observational study. From November 2020 to October 2023, 10 patients with refractory wounds after spinal internal fixation operation were admitted to the Department of Burns and Plastic Surgery of Changde Hospital of Xiangya School of Medicine of Central South University. They were 3 males and 7 females, aged 35 to 68 years. There were 6 cases of thoracolumbar tuberculosis, 3 cases of thoracolumbar fracture, and 1 case of recurrent sacrococcygeal chordoma with skin, soft tissue, and bone defects after radical resection. The wound areas after debridement were 6.0 cm×1.5 cm to 27.0 cm×6.5 cm. The wound repair operation was decided to perform in the primary stage or in the secondary stage according to the wound situation. Two patients with type Ⅰ wounds were treated with debridement, direct suture, and continuous irrigation and drainage with catheter after operation. Eight patients with type Ⅱ wounds were repaired with local flaps (including rotation flap with dermis-fat flap at the end), muscle flaps, or muscle flaps combined with local flaps. The flap sizes were 10.0 cm×5.0 cm to 27.0 cm×14.0 cm, and the sizes of muscle flap were 8.0 cm×5.0 cm×4.0 cm to 17.0 cm×9.5 cm×2.0 cm. The wounds in flap donor areas were sutured directly. The wound treatment methods of patients with type Ⅱ wounds were recorded. The wound healing was observed after operation. The infection and recurrence of wounds, the retention of internal fixation materials, and spinal motor function were observed during follow-up.Results:Among patients with type Ⅱ wounds, there were 3 cases applied with local flaps (including 1 case with rotation flap with dermis-fat flap at the end), 3 cases with muscle flaps (including 1 case with latissimus dorsi muscle flap and 2 cases with erector spinal muscle flaps), and 2 cases with muscle flaps (1 case with latissimus dorsi muscle flap and 1 case with erector spinal muscle flap) combined with local flaps. Only 1 case with secondary defects after radical surgery of sacrococcygeal chordoma had poor wound healing which healed after dressing change, and the wounds of the remaining 9 cases all healed well. During the follow-up of 4 to 18 months, no infection or recurrence of local wounds developed in 10 patients, the internal fixation materials were not loosening, and there was no significant limitation in spinal motor function.Conclusions:For refractory wounds after spinal internal fixation operation, according to the wound type of patients, debridement, suture, irrigation, and drainage in the primary stage, or transplantation of local flaps, muscle flaps, muscle flaps combined with local flaps are performed in the primary stage or in the secondary stage. These methods are proved to have reliable therapeutic effects, not only repairing the wounds, but also retaining the internal fixation materials.

Hepatic fibrosis is a pathological process of chronic liver injury. Without timely intervention and treatment， liver fibrosis may eventually lead to liver cirrhosis and cancer. Janus kinase （JAK）/signal transducer and activator of transcription （STAT） signaling pathway is closely associated with the occurrence and development of liver fibrosis. Based on this， this paper summarized and analyzed the mechanism and effects of active ingredients and compounds of traditional Chinese medicine improving liver fibrosis based on JAK/STAT signaling pathway. It is found that the active ingredients and compounds of traditional Chinese medicine that promote blood circulation and remove blood stasis （ingredients such as ethanol extract of Euonymus alatus and paclitaxel， as well as compounds such as Ershiwuwei songshi pill and Ganfukang）， clear away heat and toxic material （ingredients such as betulinic acid， total flavonoids from Persicaria perfoliata， as well as compounds such as Pianzaihuang and Kehuang capsules）， and sooth the liver and promote qi circulation （ingredients such as fraxetin and cucurbitacin B， as well as compounds such as Chaihu shugan powder and Xiaochaihu decoction） can all relieve liver fibrosis by inhibiting the activity of the JAK/STAT signaling pathway， reducing inflammatory reactions， and inhibiting the proliferation of hepatic stellate cells.

Objective To establish normal reference values for left ventricular trabecular and papillary muscle mass(TPMM)in Chinese adults using MRI and to explore its impact factors.Methods A total of 168 healthy Chinese adults were retrospectively included,and compacted and total left ventricular myocardial mass(LVM)were measured using traditional and dedicated methods,respectively.TPMM was calculated from the difference between total and compacted LVM.Independent sample t-tests and analysis of variance were used to explore the differences in TPMM among genders and age groups,while multiple linear regression was used to explore the independent correlation between TPMM and age,gender,heart rate,systolic blood pressure(SBP),fasting blood glucose(FBG),and body mass index(BMI).Results TPMM for men was significantly larger than that for female(P<0.001).TPMM in the elderly group was significantly larger in female(P<0.05),but not in men.Multiple linear regression showed that BMI and SBP were both independently positively correlated with TPMM,and female and heart rate were independently negatively correlated with TPMM(P<0.05).Conclusion This study provides age-and gender-specific normal reference values for TPMM in Chinese adults.Gender,heart rate,BMI,and SBP are all independently associated with TPMM.

Objective To investigate the detection rate and grading diagnostic value of ultra-wide field swept-source optical coherence tomography angiography(UWF SS-OCTA)combined with ultra-wide field scanning laser ophthalmoscopy(UWF SLO)in diabetic retinopathy(DR)lesions.Methods In this cross-sectional study,diabetic patients attending the Ophthalmology Department of Sichuan Provincial Peoples Hospital were recruited.All participants underwent UWF SS-OC-TA,UWF SLO and fundus fluorescein angiography to detect DR lesions,including microaneurysms(MA),intraretinal hem-orrhages(IRH),nonperfusion areas(NPAs),intraretinal microvascular abnormalities(IRMAs),venous beading(VB),neovascularization elsewhere(NVE),neovascularization of the optic disc(NVD),and vitreous hemorrhage(VH).The re-sults of the combination of three imaging examinations(triple imaging)were used as the standards,evaluating the detec-tion rate and severity grading consistency in DR lesions of pairwise combinations of different imaging modalities.Results A total of 101 patients(175 eyes)were included.Compared with the triple imaging results,the detection rates of UWF SS-OCTA combined with UWF SLO for MA,IRH,NPAs,IRMAs,NVE,NVD and VH were 91％,83％,77％,69％,27％,10％and 12％,respectively,with Kappa values of 0.812,1.000,1.000,1.000,0.986,0.970 and 1.000.Compared with the triple imaging results,the combination of UWF SS-OCTA and UWF SLO demonstrated excellent consistency in grading the severity of DR(Kappa=0.943).Conclusion UWF SS-OCTA combined with UWF SLO can accurately identify MA,IRH,NPAs,IRMAs,NVE,NVD and VH,demonstrating high accuracy in DR screening and grading diagnosis,making it suitable for large-scale screening and management of DR in clinical practice.

[Objective]To analyze the value of grey-scale reversed T1-weighted(rT1)MRI in the detection of structur-al lesions of the sacroiliac joint(SIJ)in patients with axial spondyloarthritis(ax-SpA).[Methods]Fifty-two ax-SpA pa-tients who underwent both MRI and CT in our hospital within a week from February 2020 to December 2022 were retrospec-tively included.Both sacral and iliac side of each SIJ on oblique coronal images were divided into anterior,middle and pos-terior portion.Two radiologists reviewed independently three groups of MRI including T1-weighted imaging(T1WI),rT1 and T1WI+rT1 images to evaluate the structural lesions like erosions,sclerosis and joint space changes in each of the 6 re-gions of the SIJ.One of the radiologist did the evaluation again one month later.CT images were scored for lesions by a third radiologist and served as the reference standard.Intra-class correlation coefficients(ICC)were calculated to test the inter-and intra-reader agreement for the assessment of SIJ lesions.A Friedman test was performed to compare the lesion results of MRI and CT image findings.We examined the diagnostic performance[accuracy,sensitivity(SE)and specifici-ty]of different groups of MRI in the detection of lesions by using diagnostic test.A McNemar test was used to compare the differences of three groups of MRI findings.[Results]CT showed erosions in 71 joints,sclerosis in 65 and joint space changes in 53.Good inter-and intra-reader agreements were found in three groups of MRI images for the assessment of le-sions,with the best agreement in T1WI+rT1.There were no difference between T1WI+rT1 and CT for the assessment of all lesions,nor between rT1 and CT for the assessment of erosions and joint space changes(P>0.05).T1WI+rT1 yielded better accuracy and SE than T1WI in detection of all lesions(Accuracy erosions:90.3%vs 76.9%;SE erosions:91.6%vs 76.1%;Accu-racy sclerosis:89.4%vs 80.8%;SE sclerosis:84.6%vs 73.9%;Accuracy joint space changes:86.5%vs 73.1%;SE joint space changes:84.9%vs 60.4%;P<0.05).rT1 yielded better accuracy and SE than T1WI in detection of erosions and joint space changes(Accuracy erosions:87.5%vs 76.9%;SE erosions:88.7%vs 76.1%;Accuracy joint space changes:85.6%vs 73.1%;SE joint space changes:83.0%vs 60.4%;P<0.05).[Conclusions]In the detection of SIJ structural lesions in ax-SpA,rT1 improves the diagnostic perfor-mance and T1WI+rT1 is more superior to others.
