This paper summarizes Professor LU Fang's clinical experience in treating systemic lupus erythematosus （SLE） based on the differentiation and treatment of heat-toxin and blood-stasis in the collaterals. SLE is generally characterized by deficiency in origin with excess in manifestation. The core pathogenesis is heat-toxin obstructing the collaterals. During the acute active stage， the predominant pattern is blazing heat-toxin causing blood stasis， while in the chronic remitting stage， the main pattern is toxic stasis blocking the collaterals with qi and yin deficiency. Clinical treatment follows the basic principle that treat with salty-cold herbs， when heat invades internally and that assist with acrid-dispersing herbs when stasis obstructs the collaterals. The self-formulated Yimian Decoction （抑免汤） serves as the base formula and is applied in stages. During the acute active stage， it is often combined with herbs for clearing heat and detoxifying， cooling blood and resolving stasis， and unblocking the collaterals. In the chronic remitting stage， it is often combined with herbs for activating blood circulation and unblocking the collaterals， as well as tonifying qi and nourishing yin.

Forensic medicine has been designated as a first-level discipline,presenting new opportunities and challenges for the development of forensic medicine.Since the 1980s,the establishment of foren-sic medicine discipline and the cultivation of high-level forensic talents have become hot topics in the development of forensic medicine in China.Since the 13th Five-Year Plan,the forensic team of Shanxi Medical University has been aiming at the forefront,proposing the development goals of"Five First-class"and the discipline development path"Six Major Achievements".It has selected benchmark disci-plines,identified gaps in disciplinary development,unified thoughts,formulated completion timelines,concentrated superior resources,assigned tasks to individuals,and created an"Organized Fill-in-the-Blank Format"forensic medicine discipline construction model with the characteristics of the new era.The construction model of forensic medicine has achieved good results in the goals,discipline frame-work,scientific research,talent cultivation,discipline team and platform construction,forming a rela-tively complete discipline construction and management system,and accumulating valuable experience for the construction of first-level discipline and high-level talent cultivation of forensic medicine.

Metastatic dissemination is the major cause of death from breast-cancer (BC). Fusobacterium nucleatum (F.n) is widely enriched in BC and has recently been identified as one of the high-risk factors for promoting BC metastasis. Here, with an experimental model, we demonstrated that intratumoral F.n induced BC aggressiveness by transcriptionally activating Epithelial-mesenchymal transition-associated genes. Therefore, the F.n may be a potential target to prevent metastasis. Given the fact that cancer-associated fibroblasts (CAFs) are abundant in BC and located near blood vessels, we report an optogenetic system that drives CAF to in situ produce human antibacterial peptide LL37, with the characteristics of biosafety and freely intercellular trafficking, for depleting intratumoral F.n, leading to a 72.1% reduction in lung metastatic nodules number without affecting the balance of the systemic flora. Notably, mild photothermal treatment was found that could normalize CAF, contributing to synergistically inhibiting BC metastasis. In addition, the system can also simultaneously encode a gene of TNF-related apoptosis-inducing ligand to suppress the primary tumor. Together, our study highlights the potential of local elimination of tumor pathogenic bacteria to prevent BC metastasis.

Objective To investigate the clinical efficacy of Jianpi Qushi Method(a spleen-invigorating and dampness-removing approach)combined with Chinese herbal fumigation therapy in treating seborrheic alopecia of spleen deficiency with dampness-accumulation type and to observe its influence on hormone levels.Methods The observation was carried out in 104 patients with spleen deficiency with dampness-accumulation type of seborrheic alopecia,who admitted to the Department of Dermatology at Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine from January 2023 to February 2024.The patients were equally randomized into a trial group and a control group,with 52 cases in each group.The control group received oral administration of Finasteride Tablets,while the trial group was additionally treated with Jianpi Qushi Method combined with Chinese herbal fumigation therapy for 3 months.Serum hormone levels,hair loss scores,clinical symptom scores(including greasy hair,pruritus,scaling,and growth of new hair),and trichoscopic parameters of the hair in the two groups were assessed before and after treatment.After treatment,the clinical efficacy and adverse reactions in the two groups were also evaluated.Results(1)After 3 months of treatment,the total effective rate in the trial group was 94.23％(49/52)and that in the control group was 73.08％(38/52).The trial group demonstrated significantly superior efficacy compared to the control group(tested by chi-square test,P<0.01).(2)After treatment,both groups exhibited a significant decrease in serum testosterone level(P<0.05)and a significant increase in serum estradiol level(P<0.05)compared to those before treatment.Notably,the trial group showed a more pronounced reduction in testosterone and a greater elevation in estradiol than the control group(P<0.01).(3)Both groups displayed a significant reduction in hair loss scores after treatment(P<0.05),and the trial group achieved a markedly greater decrease than the control group(P<0.01).(4)After treatment,the clinical symptom scores for greasy hair,pruritus,scaling,and growth of new hair significantly decreased in both groups compared to those before treatment(P<0.05).And the trial group exhibited significantly greater improvements in the scores of all symptoms than the control group(P<0.01).(5)After treatment,both groups showed a significant increase in hair density(hairs/cm2)and count of upright regrowing hair(P<0.05),along with a significant decrease in vellus hair count,hair count in the single hair follicle,and count of perifollicular keratosis(P<0.05).The trial group demonstrated significantly superior improvements in all trichoscopic parameters compared to the control group(P<0.01).(6)No significant adverse reactions were observed in either group during the treatment period,indicating a favorable safety profile for both therapeutic approaches.Conclusion Jianpi Qushi Method combined with Chinese herbal fumigation therapy exerts significant efficacy in treating seborrheic alopecia of spleen deficiency with dampness-accumulation type.The combined therapy is effective on regulating hormone levels,promoting hair regeneration,and alleviating symptoms such as greasy hair and pruritus,and demonstrates favorable safety.

Therefore, recent research literature on the genes, proteins, and molecular substances involved in lipid metabolism during the pathogenesis of gallstones has been conducted. This study aimed to determine the role of lipid metabolism in the pathogenesis of gallstones and provide insights for future studies using previous research in genomics, metabolomics, transcriptomics, and other fields.

Objective To evaluate the value of high-resolution computed tomography(HRCT)signs combined with artificial intelligence(AI)quantitative indexes in differentiating mycoplasma pneumoniae pneumonia(MPP)from bacterial pneumonia(BP)in adults.Methods A total of 100 patients with adult MPP and 100 with adult BP were selected.Univariate and multivariate logistic regression analyses were used to identify independent factors that contribute to the differentiation of these two types of pneumonia.The receiver operating characteristic(ROC)curve and area under the curve(AUC)were employed to evaluate the discrimination ability of the two types of pneumonia.Results A comparison of gender and age between the two groups revealed statistically significant differences(P＜0.05).A comparison of bronchial wall thickening,bud sign,and solid shadows between the two groups yielded statistically significant differences(P＜0.05),while small nodules did not(P＞0.05).AI-based quantification revealed significant differences in distribution of inflammatory foci,consolidation/total lesion ratio,ground-glass opacity(GGO)/total lesion ratio,consolidation density,and GGO density(P＜0.05).Univariate and multivariate logistic regression analyses revealed that left upper lobe(％),left lower lobe(％),right upper lobe(％),right middle lobe(％),and right lower lobe(％)were independent factors that contributed to the identification of the two types of pneumonia.The AUC for HRCT signs alone,AI quantitative indexes alone,and HRCT signs combined with AI quantitative indexes in differentiating the two types of pneumonia were 0.715[95％confidence interval(CI)0.643-0.787],0.822(95％CI 0.764-0.881),and 0.853(95％CI 0.801-0.905),respectively.The utilization of HRCT signs combined with AI quantitative indexes had been demonstrated to possess a substantial capacity to accurately identify two types of pneumonia.Conclusion HRCT signs combined with AI quantitative indexes can improve the accuracy of differentiating MPP from BP in adults.

Objective:To investigate the efficacy and safety of fluoroscopically-guided percutaneous gastrostomy (FGPG) for establishing enteral nutrition access in the treatment of esophageal fistula after radiotherapy for cervical esophageal cancer (CEC).Methods:A retrospective analysis was conducted on the clinical data of 54 patients who underwent FGPG due to esophageal fistula after radiotherapy for CEC at our department from November 2009 to August 2019. All patients received endoscopy before radiotherapy, and CEC was pathologically confirmed. Enteral nutrition support was offered through a gastrostomy tube postoperatively. The success rate of FGPG, complications, and healing of perforation were recorded and analyzed.Results:FGPG was successfully performed in all 54 patients (100%). During the 12-month follow-up, 50 patients (92.6) survived while four (7.4%) died. Among 36 patients with esophagomediastinal fistula, 32 (88.9%) healed in a median of 12 weeks; of 18 patients with esophagotracheal fistula, 8 (44.4%) healed in a median of 18 weeks. Thus, patients with esophagomediastinal fistula had a significantly higher healing rate ( P<0.01) and shorter healing time ( P=0.017). Gastrostomy tube-related complications were minimal, and no serious complication was noted. Conclusions:FGPG is effective for the treatment of esophageal fistula after CEC radiotherapy and may be an alternative treatment for esophageal fistula.

Objective To explore the effect of transcutaneous auricular vagus nerve stimulation(taVNS)on postoperative recovery of gastrointestinal function in gynecological laparoscopic surgery patients.Methods Ninety-six patients who underwent elective laparoscopic total hysterectomy were selected.According to the random number table method,patients were divided into the taVNS group(group T)and the sham stimulation group(group F)with 48 patients in each group.The conventional general anesthesia method was used in both groups.The group T received taVNS once before surgery and once in the anaesthesia recovery room with 30 min per stimulation,while the group F was given sham stimulation for 30 min each.Postoperative recovery time of anal gas and defecation,the I-FEED scores on the 1st,2nd and 3rd postoperative days,the GSRS score on the 3rd postoperative day were recorded.The NRS scores on the 1st and 2nd postoperative days,postoperative remedial analgesia,occurrence of postoperative adverse effects and duration of postoperative hospitalization were recorded.Results Compared with the group F,the time to first postoperative anal exhaust and defecation was significantly shorter in the group T.The I-FEED scores on the 1st,2nd and 3rd postoperative days,and the GSRS score on 3rd postoperative day were significantly decreased in the group T.The proportion of patients with postoperative gastrointestinal intolerance and postoperative gastrointestinal dysfunction were reduced in the group T(P＜0.05).NRS scores at postoperative days 1,and 2 were decreased and the incidence of postoperative nausea was lower(P＜0.05).There were no significant differences in postoperative remedial analgesia,the occurrence of postoperative vomiting,dizziness,bradycardia and hypotension,and duration of postoperative hospitalization in the two groups of patients(P＞0.05).Conclusion taVNS can improve the recovery of postoperative gastrointestinal function,reduce postoperative nausea and alleviate postoperative pain in laparoscopic total hysterectomy patients.

With the continuous development of minimally invasive technique and people's increasing health awareness, the demand for minimally invasive hallux valgus surgery has continued to rise in recent years. Minimally invasive hallux valgus surgery techniques have also evolved from mere bone grinding advertised by informal healthcare institutions in the early years, to continuous development, improvement, and iteration. From the first generation of osteotomies without internal fixation, to the second generation of linear osteotomies with intramedullary fixation using Kirschner's pins inserted into the proximal metatarsal after pushing the metatarsal head laterally, to the third generation, which utilizes milling drills for minimally invasive Chevron osteotomy, employing a lever for reduction and strong fixation with cannulated screws, their correction capability has been continuously improved, their strength of internal fixation has gradually increased, and the balance of soft tissues has also been improved. Notably, there are also certain complications of minimally invasive hallux valgus surgery, such as malunion, recurrence, vascular nerve injury, and hallux varus, etc. Furthermore, it is more difficult to control the metatarsal head position and the metatarsophalangeal joint congruency under the minimally invasive incision, and the special minimally invasive instruments require certain experience to use, which makes minimally invasive hallux valgus surgery have a learning curve. Many scholars have introduced their own experiences and tips during their practice, such as recommendations on osteotomy direction, recommendation of using a Kirschner pin to assist metatarsal head three-dimensional correction, and optimization of percutaneous screw placement, which will help more doctors better carry out this surgery, and also promote further technical improvement to serve more patients.

Objective:To observe the clinical efficacy of the modified crowbar-assisted minimally invasive Chevron osteotomy for the treatment of hallux valgus.Methods:A total of 42 patients with hallux valgus who underwent modified crowbar-assisted minimally invasive Chevron osteotomy at Huashan Hospital of Fudan University for hallux valgus from January 2019 to July 2022 were retrospectively analyzed. There were 3 males and 39 females, aged 42.3±8.7 years (range, 26-60 years); 18 left-sided and 24 right-sided, with body mass index 22.9±2.3 kg/m 2. According to the size of the hallux valgus angle (HVA), 26 patients were divided into the mild group (15°≤HVA<20°) and 16 patients were divided into moderate group (20°≤HVA≤40°). All patients were treated with modified crowbar-assisted Chevron osteotomy. The preoperative and postoperative HVA, intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society metatarsophalangeal interphalangeal scale (AOFAS Hallux MTP-IP scale) were compared. Results:All patients successfully completed the operation and were followed up for an average of 22.3±6.5 months (range, 18-30 months). The HVA, IMA, and DMAA in the mild group at the last follow-up were 6.6°±1.8°, 8.1°±1.8°, and 4.3°±1.1°, respectively, which were significantly lower than those before operation 17.8°±1.4°, 12.5°±1.5°, and 7.6°±2.4° ( P<0.05). The HVA, IMA, and DMAA in the moderate group at the last follow-up were 7.6°±2.1°, 8.8°±1.6°, and 4.8°±2.9°, respectively, which were significantly lower than those before operation 32.3°±3.5°, 14.8°±3.5°, and 12.7°±5.4° ( P<0.05). At the last follow-up, there was no significant difference in HVA, IMA, or DMAA between the two groups ( P>0.05). The differences of HVA, IMA, and DMAA before and after operation in the moderate group were 24.7°±2.6°, 6.0°±2.3°, and 7.9°±3.8°, respectively, which were greater than those in the mild group 11.2°±1.7°, 4.4°±1.6°, and 3.3°±1.6°, and the differences were statistically significant ( P<0.05). At the last follow-up, the VAS score of the mild group decreased from 2.6±2.0 before surgery to 0.4±0.2, and the difference was statistically significant ( t=6.014, P<0.001). The VAS score of the moderate group decreased from 3.2±2.2 before surgery to 0.4±0.3, the difference was statistically significant ( t=8.777, P<0.001). The preoperative AOFAS Hallux MTP-IP scale of the toe metatarsal joint in the mild group and the moderate group were 71.6±5.9 and 64.3±7.8, respectively, which increased to 93.3±6.0 and 92.3±6.0 at the last follow-up, and the difference was statistically significant ( P<0.05). At the last follow-up, there was no significant difference in AOFAS Hallux MTP-IP scale between the two groups ( P>0.05). Twenty-two of the 26 patients in the mild group were satisfied, and 14 of the 16 patients in the moderate group were satisfied, and the difference in satisfaction between the two groups was not statistically significant ( P>0.05). Conclusion:The clinical efficacy of the modified crowbar-assisted minimally invasive Chevron osteotomy in the treatment of hallux valgus is satisfactory, and it can effectively correct the hallux valgus deformity and improve the function of the metatarsophalangeal joint.
