ObjectiveTo observe the short-term and long-term efficacy of traditional Chinese medicine （TCM） surgical operations in treating mixed hemorrhoids. MethodsA multi-center retrospective cohort study was conducted， collecting clinical data from 17，831 mixed hemorrhoid surgery patients in 8 top-tier TCM hospitals in Jiangsu Province. Standardized and structured datasets were obtained through artificial intelligence models. Patients who underwent western surgical treatment were categorized into the western surgery group （11,646 cases）， and those receiving TCM surgical operations were categorized into the TCM surgery group （6185 cases）. Propensity score matching （1∶1 matching） was used to balance baseline data between groups. The primary outcome was the one-year recurrence rate， and secondary outcomes included the main symptoms （rectal bleeding， degree of prolapse） and secondary symptoms （anal distension， anal edema， wound secretion and exudation， anal stenosis， residual skin tags， perianal itching， and anal pain） measured on days 7， 28， and 60 after discharge. ResultsAfter matching， 2194 patients were included in each group. Symptom scores showed that at 28 days after discharge， the TCM surgical group had superior improvement in rectal bleeding ［OR=5.786， 95%CI （3.092，10.827）］， degree of prolapse ［OR=4.510， 95%CI （1.649，12.333）］， and anal edema ［OR=3.188， 95%CI （1.295，7.845）］ compared to the western surgical group. At 60 days post-discharge， the TCM group still showed advantages in improving rectal bleeding ［OR=5.237， 95%CI （1.077，25.464）］ and anal pain ［OR=11.697， 95%CI （1.186，115.336）］ （P＜0.05）. Long-term follow-up showed that the one-year recurrence rate in the TCM surgery group was 1.1% （8/726）， while that in the western surgery group was 2.3% （10/444）， with no statistically significant difference between the two groups （P＞0.05）. ConclusionBased on real-world data， TCM surgical treatment for mixed hemorrhoids shows significant short-term symptom improvement， particularly in terms of hemostasis， reducing swelling， and alleviating prolapse of anal masses.

ObjectiveTo explore the effects of Jingui Shenqiwan （JSW） and Liuwei Dihuangwan （LDW） on the reproductive ability and brain function of normal mice and compare the actions of the two medications. MethodsSeven groups of female and male mice were divided at a ratio of 2∶1. Except for the control group， the other six groups were as follows： a group of both males and females receiving JSW （3.0 g·kg^-1）， a group of both males and females receiving LDW （4.5 g·kg^-1）， a group of males receiving water and females receiving JSW， a group of males receiving water while females receiving LDW， a group of females receiving water while males receiving JSW， and a group of females receiving water while males receiving LDW. Each group was administered the drug for 14 days and then caged together at a 2∶1 （female∶male） ratio to detect the number of pregnant mice and calculate the pregnancy rate. Pregnant mice continued receiving the drug until they naturally gave birth， which was followed by the observation of newborn mice， calculation of their average number， and the measurement of the offspring's preference for sugar water and neonatal recognition index. At the end of the experiment， the weights of the thymus and spleen were measured to calculate the organ coefficients， and mRNA or protein expression was analyzed in the brain and testes or ovaries. A 1% sucrose solution was used to examine the euphoria of their brain reward systems， while novel object recognition test （NOR） was applied to assess their memory capabilities. mRNA expression was detected using real-time quantitative polymerase chain reaction （Real-time PCR） assay， and protein expression was analyzed with Western blot. ResultsCompared with the control group， oral administration of JSW to both male and female mice for 14 days significantly increased the pregnancy rate of female mice on day 2 after being caged together （P<0.05）， while LDW showed a trend but no statistical significance. Additionally， compared with the control group， JSW could upregulate the gene expression of gonadotropin-releasing hormone （GnRH） in the thalamus， as well as reproductive stem cell factor （SCF） and tyrosine kinase receptor （c-Kit） in the testes and reproductive stem cell marker mouse vasa homologue （MVH） in the ovaries， upregulate the expression of proteins influencing neuronal functional activity， such as brain-derived neurotrophic factor （BDNF）， in hippocampal neurons （P<0.05）， and enhance sucrose preference in male mice （P<0.05）. Compared with the control group， JSW significantly increased sucrose preference and novel object recognition index in offspring mice （P<0.05）， which was related to the upregulation of hippocampal dopamine D1 receptor （D1R） and N-methyl-D-aspartate receptor （Nmdar） gene expression. Compared with the control group， both JSW and LDW could upregulate the protein expression of glucocorticoid receptor （GR）， BDNF， and tyrosine kinase receptor B （TrkB） in the hippocampus of offspring mice （P<0.05）. ConclusionJSW significantly enhances the reproductive ability of normal mice， which is not only related to the release of gonadotropin but also associated with its regulation of brain function. Additionally， JSW has a certain regulatory effect on the brain function of the offspring mice.

ObjectiveTo explore the effect of Shenge Bushen Capsules （SBC） on sexual development in normal 3-week-old mice. MethodsThe experiment consisted of two parts. In the first part， mice were divided into four groups： The control group and the low， medium， and high-dose SBC groups （234.7， 469.4， 938.7 mg·kg^-1， respectively）. In the second part， mice were divided into four groups： Control group， Pseudostellariae Radix polysaccharide （PRP） group， total flavonoids group， and SBC group， all receiving a dose of 469.4 mg·kg^-1. After 7 days of administration， the vaginal opening of female mice and the descent of testes and scrotum in male mice， as well as the ovarian and testicular organ indices， were observed. After 4 weeks of administration， female and male mice were housed together for 2 days， and the pregnancy rate of females was monitored. After delivery， the pregnant female mice continued receiving the treatment for 4 weeks， and the sexual development of their offspring， including vaginal opening， testicular descent， and organ indices of ovaries and testes， was observed. Serum sex hormones were measured by enzyme-linked immunosorbent assay （ELISA）， and the expression of gonadotropin-releasing hormone （GnRH） and growth hormone （GH） proteins in the hypothalamus was assessed by Western blot. ResultsCompared with the control group， there was no significant effect on the vaginal opening of female mice or the descent of testes in male mice after 7 days of SBC administration. After 4 weeks of administration， the pregnancy rate in the low-dose group was significantly reduced （P<0.05）， but no significant effects were observed in the other groups. The three doses of SBC did not significantly affect the ovarian or testicular organ indices， and there was no significant upregulation in the expression of GnRH or GH in the hypothalamus. The primary component of SBC， Pseudostellariae Radix polysaccharide， significantly reduced the vaginal opening in female mice after 7 days of administration （P<0.05）. After 4 weeks， the serum estradiol levels of non-pregnant female mice were decreased （P<0.05）， but there was no significant effect on the expression of GnRH or GH proteins in the hypothalamus of either male or female mice. Additionally， there were no significant effects on precocious puberty indicators， such as vaginal opening and testicular descent， in the offspring mice. ConclusionSBC does not significantly promote precocious puberty in young mice， and it does not have any noticeable effects on the pregnancy rate of adult mice or the sexual development of their offspring.

BACKGROUND:This study provided insight into the molecular mechanisms by which exogenous basic fibroblast growth factor(bFGF)promotes wound healing. OBJECTIVE:To investigate the effect of exogenous bFGF on macrophage phenotype transition and granulation regeneration during wound repair in rats. METHODS:(1)In vitro experiment:Cells were divided into normal control group,low-dose bFGF group,high-dose bFGF group,and bFGF+valproic acid group.100 and 200 μg/L bFGF was added into the cell culture medium of low-dose bFGF group and high-dose bFGF group,respectively,while 200 μg/L bFGF and 20 mmol/L valproic acid were added into the cell culture medium of valproic acid group.EdU test,scratch test and tubule formation test were used to detect the effects of bFGF on proliferation,migration and angiogenesis of human umbilical vein endothelial cells.(2)In vivo experiment:Sprague-Dawley rats were randomly divided into model group,low-dose bFGF group,high-dose bFGF group and bFGF+valproic acid group.The open wound model of full-thickness skin defect was established in low-dose bFGF group,high-dose bFGF group and bFGF+valproic acid group.Rats in the low-and high-dose bFGF groups were given 100 and 200 μg/L bFGF through subcutaneous injection,while those in the bFGF+valproic acid group received subcutaneous injection of 200 μg/L bFGF and intraperitoneal injection of 10 mg/kg valproic acid.The wound healing rate of rats was detected at 7 and 14 days of administration.TUNEL was used to detect the apoptosis of cells in wound tissue.Enzyme linked immunosorbent assay was used to detect the serum levels of malondialdehyde,superoxide dismutase,tumor necrosis factor-α and interleukin-10.Immunofluorescence detection was conducted to detect the phenotypic transformation of macrophages in wound tissue.Immunohistochemistry was used to detect the expression of proliferating cell nuclear antigen,platelet endothelial cell adhesion molecule-1(CD31)and vascular endothelial growth factor in wound tissue.Western blot was used to detect the expression of Notch1 and Jagged1 in wound tissue. RESULTS AND CONCLUSION:(1)Compared with the normal control group,bFGF could significantly promote the proliferation,migration and angiogenesis of human umbilical vein endothelial cells in a dose-dependent manner.(2)Compared with the model group,bFGF could significantly promote wound healing,downregulate the rate of apoptosis in wound tissue,decrease the levels of malondialdehyde and tumor necrosis factor-α in serum,increase the levels of superoxide dismutase and interleukin-10,promote the conversion of macrophages to type M2 in wound tissue,upregulate the expression of proliferating cell nuclear antigen,CD31 and vascular endothelial growth factor in wound tissue,and inhibit the expression of Notch1 and Jagged1 in a dose-dependent manner.Valproic acid could partially reverse the promoting effect of bFGF on wound healing.To conclude,bFGF can significantly promote wound healing and granulation regeneration and induce the conversion of macrophages to M2,which may be related to the regulation of Notch1/Jagged1 signaling pathway.

Objective: To investigate the protective effect of dulaglutide on lipopolysaccharide (LPS)-induced inju- ry in MLE-12 cells. Methods: An in vitro model of acute lung injury was established by inducing MLE-12 cells with LPS ( 1 μg/mL) , followed by treatment with dulaglutide for 24 hours. The cells were divided into four groups : CON group , LPS group , LPS + 100 nmol/L dulaglutide group , and LPS + 200 nmol/L dulaglutide group. Protein and RNA were extracted from each group. The mRNA levels of inflammatory factors , including interleukin (IL)-6 , tumor necrosis factor-α (TNF-α ) , IL-1β , monocyte chemotactic protein 1 (CCL2) , C-X-C motif chemokine lig- and (CXCL) 1 and CXCL2 , were detected by qRT-PCR. Cell apoptosis was assessed by TUNEL assay , and the expression levels of phosphorylated protein kinase B (P-Akt) and phosphorylated extracellular signal-regulated ki- nase (P-Erk) were measured by Western blot. Results: Compared with the CON group , the LPS group showed in- creased mRNA levels of inflammatory mediators (TNF-α , IL-6 , IL-1β , CCL2 , CXCL1 , and CXCL2) , increased TUNEL-positive cells , and elevated expression of P-Akt and P-Erk proteins. Compared with the LPS group , the LPS + 100 nmol/L dulaglutide treatment group exhibited reduced mRNA levels of TNF-α , IL-6 , IL-1β , CCL2 , CXCL1 , and CXCL2 , decreased TUNEL-positive cells , and downregulated expression of P-Akt and P-Erk pro- teins. However, the LPS + 200 nmol/L dulaglutide treatment group showed less pronounced improvement in inflam- matory factors compared to the LPS + 100 nmol/L dulaglutide group. Conclusion Dulaglutide has a protective effect on LPS-induced injury in MLE-12 cells , potentially through inhibiting Akt and Erk phosphorylation , thereby reducing the expression of inflammatory mediators and alleviating inflammatory damage , ultimately protecting the lungs.

Objective To explore the clinical and imaging manifestations of posterior tibial tendon dysfunction(PTTD).Methods A retrospective selection was conducted on 61 patients with clinically diagnosed PTTD.According to the classification criteria of Johnson and Strom,8 patients were classified as stage 1,17 as stage 2,20 as stage 3,and 16 as stage 4.The clinical manifestations and imaging features of patients were summarized at each stage.Results Among the 8 patients with stage 1 PTTD,no abnormalities were found on X-ray examination of the weight-bearing foot,while MRI revealed posterior tibial tendon(PTT)tendinitis in 4 cases(50.0％).For stage 2 patients(n=17),X-ray examination of the weight-bearing foot showed a decrease in the longitudinal arch of the foot in 15 patients(88.2％).MRI mainly revealed PTT degeneration in 12 cases(70.6％),PTT tears in 2 cases(11.8％),and other structural injuries in 5 cases(29.4％).For stages 3-4 patients(n=36),X-ray examination of the weight-bearing foot showed flatfoot in all cases.MRI mainly revealed PTT degeneration in 12 cases(33.3％),PTT tears in 24 cases(66.7％),spring ligament injuries in 33 cases(91.7％),and deltoid ligament injuries in 23 cases(63.9％).Conclusion Patients with stage 1 PTTD often have a normal foot longitudinal arch and may present with PTT tendinitis.Middle-aged females are more commonly affected by advanced PTTD,which is characterized by gradual decrease and collapse of the foot arch,accompanied by varying degrees of PTT degeneration and tears.The spring ligament injuries and deltoid ligament are frequently involved in structural injuries associated with PTTD.

Erosive pustular dermatosis of the scalp (EPDS) is a rare superficial skin inflammatory disease that occurs on the scalp, and its pathogenesis is still unclear. Its clinical manifestations are similar to those of infective inflammation and malignant tumors, and its diagnosis is highly dependent on non-specific pathological changes, so the diagnosis is relatively difficult. Clinically, topical glucocorticoids are the main treatment method, but treatment outcomes vary greatly among individuals, and patients with refractory EPDS need other treatment methods. EPDS generally requires long-term topical glucocorticoid therapy, and adverse drug reactions are common. This review summarizes research progress in EPDS in recent years, in order to improve clinicians' understanding of this disease.

Congenital triangular alopecia is a kind of non-inflammatory and non-cicatricial alopecia, and most cases develop this disease at the ages of 2 - 9 years. The pathogenesis of congenital triangular alopecia is still unclear, and there is a lack of effective treatments. Congenital triangular alopecia is rather liable to be misdiagnosed and erroneously treated, and dermoscopy helps confirm the diagnosis. This review summarizes the progress in the epidemiology, pathogenesis, clinical diagnosis, and treatment of congenital triangular alopecia.

Objective To compare the clinical and functional differences between transoral and submandibular approach in mandibu-lar segmental resection and reconstruction with free fibula flaps(FFFs).Methods Patients who underwent mandibular segmental re-section and FFFs reconstruction in the Department of Oral and Maxillofacial Surgery of the Affiliated Stomatological Hospital of Nanjing Medical University from January 2015 to March 2023 were retrospectively analyzed.All cases were divided into transoral approach and submandibular approach groups.Clinical characteristics of the patients were recorded including age,gender,follow-up time,pathologi-cal diagnosis,body mass index(BMI),American Society of Anesthesiologists(ASA)classification,James Brown classification of mandibular defect and number of fibular segments.The perioperative indexes,such as average operation time,average bleeding vol-ume,average blood transfusion volume,average drainage volume,average hospitalization time and postoperative complications such as malocclusion,fistula,infection,flap failure,and restriction of mouth opening were compared between the two groups.The University of Washington Quality of Life Questionnaire was used to investigate the appearance,function of swallow and speech more than 6-month postoperatively.Results The average intraoperative bleeding and postoperative drainage were significantly lower in the transoral ap-proach group than in the submandibular approach group(P=0.013 9,P=0.001 9).The appearance score was significantly higher in the transoral approach group than in the submandibular approach group(83.52±12.37)vs.(67.19±13.64)(P＜0.000 1).The differ-ences between the two groups in other variables were not statistically significant.Conclusion Cases of transoral approach had signifi-cantly better aesthetic outcomes compared with those of submandibular approach.

Depressive disorder is a common psychiatric condition clinically characterized by impaired cognitive function， which profoundly affects patients' daily living and social functioning. Despite extensive research on the mechanism underlying the interaction between ghrelin and depressive disorder， comprehensive reviews， summary， and systematic organization of these findings remain lacking. To address this gap， this study aims to conduct a systematic evaluation of the effects and mechanisms of ghrelin on cognitive function in patients with depressive disorder， thereby providing references for targeted clinical interventions. On October 20， 2024， literature exploring the role and mechanisms of ghrelin in improving cognitive function in depressive disorder was sourced from the CNKI， PubMed and Web of Science databases， covering the period from the inception of the database till October 20， 2024. Two researchers independently conducted literature screening and data extraction. Ultimately， 9 articles were included in this review. The findings suggest that ghrelin improves cognitive function in patients with depressive disorder through multiple mechanisms， including mitigating inflammatory responses， modulating oxidative stress， and activating the cyclic adenosine monophosphate response element binding protein-brain-derived neurotrophic factor （CREB-BDNF） signaling pathway.
