ObjectiveTo observe the effects of the Fuyuan Tongluo prescription （composed of Astragali Radix， Carthami Flos， Spatholobi Caulis， Liquidambaris Fructus， Lycopodii Herba， Centellae Herba， etc.） in the treatment of restenosis with collateral obstruction syndrome after interventional operation of lower limb arteriosclerosis obliterans， and its impact on the primary patency rate. MethodsA total of 88 patients with collateral obstruction syndrome after interventional surgery for lower limb arteriosclerosis obliterans were randomly divided into two groups. The control group （n₁=44） received dual antiplatelet therapy with aspirin and clopidogrel. The observation group （n₂=44） was treated with Fuyuan Tongluo prescription non-decocted granules in addition to aspirin and clopidogrel. Both groups received treatment for 24 weeks and were followed up for 36 weeks. The changes in primary patency rate， symptom scores， ankle-brachial index （ABI）， coagulation function， and inflammatory markers before and after treatment were compared between the two groups. ResultsFor primary patency rate， after 36 weeks of treatment， the observation group had a significantly better primary patency rate than the control group （χ²=4.14，P<0.05）. After 24 weeks of treatment， there was no significant difference in primary patency rate between the two groups. Clinical efficacy comparison： Based on symptom quantification scores， and using the Nimodipine method as a reference， the overall efficacy of the observation group was superior to that of the control group after 24 weeks of treatment （χ²=2.24，P<0.05）. ABI levels： The observation group had a higher ABI than the control group after 24 and 36 weeks of treatment （P<0.05）. Coagulation function indicators： After 24 and 36 weeks of treatment， D-dimer and fibrinogen levels in both groups were lower than before treatment （P<0.05）. Inflammatory markers： After 24 and 36 weeks of treatment， CRP levels in the observation group were lower than those in the control group （P<0.05）. There were no significant differences in white blood cell （WBC） and erythrocyte sedimentation rate （ESR） levels before and after treatment between the two groups. ConclusionAdding Fuyuan Tongluo prescription non-decocted granules to dual antiplatelet therapy can improve the primary patency rate of the affected vessels in patients with lower limb arteriosclerosis obliterans after interventional surgery. Longer use of Fuyuan Tongluo prescription can significantly improve clinical symptoms， demonstrating clinical application value.

ObjectiveTo clarify the anti-inflammatory and lung-protective effects of Yantiao prescription on lipopolysaccharide （LPS）-induced acute lung injury （ALI）， and to explore the impact of Yantiao prescription on the metabolic pathways of arachidonic acid （AA） in vivo. MethodsThirty male C57BL/6J mice were randomly divided into the following groups based on body weight： normal group， model group， dexamethasone group （2 mg·kg^-1）， low-dose Yantiao prescription group （18 g·kg^-1）， and high-dose Yantiao prescription group （36 g·kg^-1）， with 6 mice in each group. The ALI mouse model was established by intraperitoneal injection of LPS. The treatment groups received oral gavage once a day for 7 consecutive days， and serum and lung tissue were collected at the end of the experiment. The content of pro-inflammatory cytokines tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in serum was detected by enzyme-linked immunosorbent assay （ELISA）. Hematoxylin-eosin （HE） staining was used to assess lung tissue pathology. The wet/dry weight ratio （W/D） and myeloperoxidase （MPO） activity in lung tissue were measured. The content of AA metabolites in serum and lung tissue was measured by liquid chromatography triple quadrupole-mass spectrometry （LC-MS/MS）. ResultsCompared with the conditions in the normal group， the content of serum pro-inflammatory cytokines TNF-α， IL-1β， and IL-6 in the model group was significantly increased （P<0.01）. The alveolar structure in mice was severely damaged， with markedly thickened alveolar walls and extensive inflammatory cell infiltration. The W/D ratio and MPO activity in lung tissue were significantly increased （P<0.01）. The content of AA metabolites， including prostaglandin D₂ （PGD₂）， prostaglandin E₂ （PGE₂）， 11（S）-hydroxy-eicosatetraenoic acid ［11（S）-HETE］， and 5-hydroxy-eicosatetraenoic acid （5-HETE） in serum and lung tissue was significantly increased （P<0.05）， while the content of 11，12-epoxyeicosatrienoic acid （11，12-EET） and 14，15-epoxyeicosatrienoic acid （14，15-EET） in serum was significantly decreased （P<0.01）. Compared with the results in the model group， the content of serum pro-inflammatory cytokines TNF-α， IL-1β， and IL-6 in the dexamethasone group， low-dose Yantiao prescription group， and high-dose Yantiao prescription group was significantly reduced （P<0.05）. Mild thickening of alveolar walls， scattered inflammatory cell infiltration， and relatively intact tissue structure with improved alveolar architecture were observed. The W/D ratio and MPO activity in lung tissue were significantly reduced （P<0.01）. The content of AA metabolites PGD₂， PGE₂， 11（S）-HETE， and 5-HETE in serum from the dexamethasone group was significantly decreased （P<0.05）， while the content of 14，15-EET in serum significantly increased （P<0.01）， and the content of 5-HETE in lung tissue significantly decreased （P<0.01）. In the low-dose and high-dose Yantiao prescription groups， the content of AA metabolites PGD₂， PGE₂， 11（S）-HETE， and 5-HETE in serum and lung tissue was significantly decreased （P<0.05）， while the content of 11，12-EET in both serum and lung tissue was significantly increased （P<0.05）. ConclusionYantiao prescription has significant protective effects against LPS-induced ALI， which are related to its regulation of AA metabolic pathways in vivo.

ObjectiveTo investigate the analgesic effect of Tuina at the "Weizhong （BL 40）" on neuropathic pain in a rat model of chronic constriction injury （CCI） of the sciatic nerve and its potential central spinal mechanisms. MethodsThirty-two Sprague-Dawley rats were randomly divided into four groups （8 rats in each group）， sham-operated group， model group， Tuina group， and blockade group. The CCI model was established in the model group， Tuina group， and the blockade group by ligating the sciatic nerve with catgut， while the sham-operated group underwent only sciatic nerve exposure without ligation. From postoperative day 4 to day 14， rats in the Tuina group and the blockade group received Tuina manipulation at the "Weizhong （BL 40）" using a dynamic pressure distribution measurement system （5 N pressure， 2 Hz frequency， 10 min per session， once daily）. The blockade group also received intraperitoneal injections of the microglial inhibitor minocycline （10 mg/kg） once daily. The sham-operated and the model group underwent the same handling and fixation as the Tuina group without actual Tuina. Mechanical withdrawal threshold （MWT） and paw withdrawal latency （PWL） were measured before surgery and on day 3， 7， 10， and 14 post-surgery. Transmission electron microscopy was used to evaluate sciatic nerve injury and repair， measuring axon diameter and total myelinated fiber diameter to calculate the g-ratio. Western Blotting was performed to detect the protein levels of ionized calcium-binding adapter molecule 1 （Iba-1）， CD206， CD68， interleukin-10 （IL-10）， and β-endorphin （β-EP） precursor pro-opiomelanocortin （POMC） in the ipsilateral spinal dorsal horn. ResultsCompared with the sham-operated group， the model group showed significantly reduced MWT and PWL on day 3， 7， 10， and 14 （P＜0.01）. Compared with the model group， the Tuina group and the blockade group showed increased MWT and PWL on day 10 and 14 （P＜0.05）. Compared with the Tuina group， the blockade group exhibited higher MWT on day 7， 10， and 14， and higher PWL on day 10 （P＜0.05）. Sciatic nerve pathological morphology revealed intact and well-structured myelin in the sham-operated group， while the model group exhibited myelin collapse， distortion， and myelin ovoid formation. The Tuina group displayed partially irregular myelin with occasional myelin collapse， whereas the blockade group exhibited partial myelin irregularities and phospholipid shedding. Compared with the sham-operated group， the model group showed a decreased g-ratio and increased levels of Iba-1 and CD68 in the spinal dorsal horn （P＜0.05 or P＜0.01）. Compared with the model group， the Tuina group and the blockade group exhibited an increased g-ratio and reduced Iba-1 and CD68 levels. Additionally， the Tuina group showed elevated levels of CD206， IL-10， and POMC， whereas the blockade group had decreased CD206 levels （P＜0.05）. ConclusionTuina at "Weizhong （BL 40）" alleviates neuropathic pain in CCI rats， potentially by regulating microglial activation in the spinal cord， inhibiting M1 polarization while promoting M2 polarization， and activating the IL-10/β-EP pathway to exert analgesic effects.

OBJECTIVE: To investigate the clinical effects of thread-dragging therapy on gangrene of non-ischemic diabetic foot ulcers (NIDFU). METHODS: A total of 136 patients with NIDFU were recruited from the Department of Peripheral Vascular Surgery, Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine between June 21, 2021 and February 1, 2023, and randomized into an intervention group and a control group, with 68 cases in each group. Both groups received basic treatment. The intervention group was treated with thread-dragging therapy, while the control group was treated with debridement combined with routine dressing changes after surgery. Both groups were treated continuously for 2 months. The amputation rates and changes in the ulcer area were compared between the groups. The inflammatory response index including peripheral white blood cells (WBCs), neutrophil percentage (NEUT%), C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), and interleukin 6 (IL-6) were compared between the two groups. RESULTS: After treatment, the ulcer areas in the intervention group were significantly smaller than that of the control group (8.50±3.88 cm² vs. 10.11±4.61 cm², P<0.05). The amputation rates of the two groups were not statistically significant (4.4% vs. 5.9%, P>0.05). Differences of WBCs count, CRP, and ESR before and after therapy in the intervention group were better than the control group (P<0.05). However, there were no significant differences in changes of NEUT%, PCT, and IL-6 between the two groups (P>0.05). CONCLUSION Thread-dragging therapy may be effective in the treatment of NIDFU, with the additional advantages of less tissue damage after healing. (Registration No. ChiCTR2100047496).

Objective: To investigate the effects of β-caryophyllene(BCP) on the browning of white adipose tissue in obese mice and the related mechanisms. Methods: An obese mouse model was establishedviaintraperitoneal injection of a high-fat diet supplemented with propylthiouracil saline solution [14.4 mg/(kg·d)] in male Kunming mice. Obesity model mice were randomly divided into a model group(Model group) and a BCP administration group(BCP-50 group); normal diet mice were set up as a control group(Control group), with 8 mice in each group. BCP administration was given by gavage at a dose of 50 mg/kg once in the morning and once in the evening in the BCP-administered group, while the rest of the group was administered by gavage with aqueous solution of Tween 80 for 4 weeks. The oral glucose tolerance test was performed at the end of 4-week administration, and mice were executed after overnight fasting at the end of the experiment, and blood samples and adipose tissues were rapidly collected for subsequent experimental tests. The kit was used to detect serological-related indexes; hematoxylin-eosin staining was conducted to observe the morphology of adipose tissue; immunohistochemical staining was carried out to observe the expression of uncoupling protein 1(UCP1) in adipose tissue; Western blot was employed to detect expression of peroxisome proliferator-activated receptor γ coactivator1-α(PGC1α), peroxisome proliferator-activated receptor γ(PPARγ), UCP1 and cannabinoid receptor 2(CNR2) proteins in epididymal white adipose(eWAT). Results: Compared with the model group, the body mass of obese mice in the BCP-50 group was significantly reduced(P<0.05), food intake was decreased(P<0.01), insulin resistance was improved(P<0.000 1), and the serum content of low-density lipoprotein cholesterol(LDL-C) and nonesterified fatty acid(NEFA) in the obese mice was significantly reduced(P<0.000 1 andP<0.01). Total cholesterol(TC), triglyceride(TG), and high-density lipoprotein cholesterol(HDL-C) contents did not change significantly. In addition, the adiposity coefficient and eWAT specific gravity of obese mice in the BCP-50 group were significantly decreased(P<0.05); the adipocytes in eWAT and BAT were reduced; and the expression of the UCP1 protein was significantly elevated(P<0.01 andP<0.05). In addition to UCP1, the expression levels of PGC1α, PPARγ, and CNR2 proteins in the eWAT of obese mice in the BCP-50 group were also significantly elevated(P<0.01,P<0.05, andP<0.001). Conclusion β-caryophyllene promotes white adipose tissue browning through up-regulating PPARγ/PGC-1α/UCP1 pathway expression, thus improving obesity.
