ObjectiveTo investigate the protective effects of Zuogui Wan （ZGW） decoction on nephrotic syndrome （NS） through the regulation of gut microbiota. MethodsThirty male Sprague-Dawley （SD） rats were randomly divided into five groups， with 6 rats in each group： The control group， model group， low-dose group， medium-dose group， and high-dose group. The NS rat model was induced by tail vein injection of 6.5 mg·kg^-1 doxorubicin. After successful modeling， the control and model groups were gavaged with normal saline （10 mL·kg^-1） twice daily， while the low- （50 mg·kg^-1）， medium- （100 mg·kg^-1）， and high-dose （200 mg·kg^-1） groups were gavaged with ZGW （10 mL·kg^-1） twice daily. All rats were administered at fixed intervals daily for 8 consecutive weeks. The therapeutic effects of ZGW on NS in rats were observed， and the optimal dose was screened. Renal and intestinal pathological changes in rats were examined. Fecal samples were collected， and 16S rDNA sequencing technology was used to detect the diversity and abundance of gut microbiota in each group. ResultsCompared with the control group， 24-hour urinary protein， serum creatinine， urea nitrogen， and cholesterol levels significantly increased in the model group （P<0.01）， while serum albumin levels decreased （P<0.01）. These changes were ameliorated in the treatment groups （P<0.05， P<0.01）. Renal pathology revealed intact and orderly arranged glomeruli and renal tubules in the control group. In the model group， glomerular atrophy， widened mesangial areas， podocyte swelling， disordered renal tubular arrangement， and numerous casts were observed. Varying degrees of glomerular atrophy and disordered renal tubular arrangement were seen in the treatment groups. Specific protein assays revealed increased serum levels of kidney injury molecule-1（KIM-1） and α1-microglobulin （P<0.01）， and significantly decreased levels of E-cadherin， Podocin， and Nephrin in renal tissues （P<0.01）， along with a significant increase in transforming growth factor-β（TGF-β） （P<0.01） in the model group. In the treatment groups， serum KIM-1 and α1-microglobulin levels decreased， E-cadherin levels significantly increased （P<0.01）， and TGF-β levels significantly decreased （P<0.01）. Podocin and Nephrin levels increased in the high-dose group （P<0.05）. Additionally， intestinal mucosal atrophy， epithelial cell edema， decreased goblet cells， and multiple inflammatory infiltrations were observed in the model group. The sequencing results of gut microbiota demonstrate that ZGW can significantly ameliorate intestinal dysbiosis in rats， restore the abundance of beneficial bacteria， and exert a profound influence on the compositional profile of gut microbiota. ConclusionZGW can alleviate renal injury in rats with nephrotic syndrome by improving gut microbiota and protecting the intestinal barrier.

Aromatherapy refers to the method of using the aromatic components of plants in appropriate forms to act on the entire body or a specific area to prevent and treat diseases. Essential oils used in aromatherapy are hydrophobic liquids containing volatile aromatic molecules， such as limonene， linalool， linalool acetate， geraniol， and citronellol. These chemicals have been extensively studied and shown to have a variety of functions， including reducing anxiety， relieving depression， promoting sleep， and providing pain relief. Terpenoids are a class of organic molecules with relatively low lipid solubility. After being inhaled， they can pass through the nasal mucosa for transfer or penetrate the skin and enter the bloodstream upon local application. Some of these substances also have the ability to cross the blood-brain barrier， thereby exerting effects on the central nervous system. Currently， the academic community generally agrees that products such as essential oils and aromatherapy from aromatic plants have certain health benefits. However， the process of extracting a single component from it and successfully developing it into a drug still faces many challenges. Its safety and efficacy still need to be further verified through more rigorous and systematic experiments. This article systematically elaborated on the efficacy of aromatic substances， including plant extracts and natural small molecule compounds， in antibacterial and antiviral fields and the regulation of nervous system activity. As a result， a deeper understanding of aromatherapy was achieved. At the same time， the potential of these aromatic substances for drug development was thoroughly explored， providing important references and insights for possible future drug research and application.

Objective To investigate the effect of genistein on the proliferation,migration and invasion of prostate cancer cells and its molecular mechanism.Methods Prostate cancer LNCaP and CWR22RV1 cells were divided into the control group(conventional culture)and the experimental group(50μmol/L genistein treatment).The effect of genistein on the proliferation of prostate cancer cells were analyzed by MTT assay.The effect of genistein on the migration and invasion of prostate cancer cells were analyzed by cell scratch assay and Transwell assay.The protein levels of epithelial interstital transformation(EMT)intermediate markers E-Cadherin,N-Cadherin,Vimentin,and tumor stem cell markers CD44 and Oct-4 were detected by Western blot assay.Results MTT assay showed that genistein could inhibit the proliferation of prostate cancer cells.The scratch closure rates of LNCaP and CWR22RV1 cells were significantly reduced in the experimental group compared with those in the control group,and the number of cells passing through the Transwell membrane was significantly reduced(P＜0.05).Western blot assay showed that genistein could down-regulate the expression levels of N-Cadherin,Vimentin,CD44 and Oct4 in prostate cancer cells,and up-regulate the expression of E-Cadherin in epithelial cells(P＜0.01).Conclusion Genistein reduces the dryness of prostate cancer cells by inhibiting the EMT process,thus reducing the proliferation,migration and invasion of prostate cancer cells.

BACKGROUND:Screw fixation of the fractured vertebral body can share the stress of implant, increase fixing strength, and help to maintain the stability of late fracture. However, whether it can assist reduction using fracture vertebral screw, but no relevant clinical reports were found at present. OBJECTIVE:To explore the effectiveness of self-designed screw-assisted reduction of fractured vertebrae. METHODS:161 cases of thoracolumbar fracture who had been hospitalized between June 2001 and June 2009 were enrol ed in this study, including 101 males and 60 females, at the age of 22-67 years, averagely 36 years. By Denis classification, 64 cases affected burst fractures and 97 flexion-compression fractures. Fracture levels involved T11 (9 cases), T12 (63 cases), L1 (74 cases) and L2 (15 cases). The self-designed method of reduction assisted with screw insertion was used. The efficacy of this reduction method was evaluated by operation time, intraoperative bleeding, fracture union time, height ratio of anterior borders of injured and normal vertebrae, sagittal Cobb’s angle, and reduction of fragments.
RESULTS AND CONCLUSION:The operation time ranged from 60 to 150 minutes, averaging 80 minutes. The intraoperative bleeding ranged from 67 to 750 mL, averaging 98 mL. The fol ow-up time ranged from 16 to 42 months in 161 patients. Fracture union time ranged from 10 to 18 weeks, averaging 12.6 weeks. The ratio of anterior heights and sagittal Cobb’s angle of fractured vertebrae were significantly improved from (54.39±9.60)%and (22.55±7.90)° respectively preoperati on to (82.80±6.63)%and (8.91°±5.85)° 12 months postoperation (P<0.05). The size of spinal canal was increased by (46.5±2.6)%postoperatively. CT scan revealed satisfactory fragment reduction and no deep infection appeared. These findings suggest that our self-designed screw-assisted reduction of the fractured vertebrae can improve the reduction quality in the treatment of thoracolumbar fractures.
