Objective To analyze the influence of different processing methods,including frying,ginger frying,and salt frying,on the volatile components of A.fructus.Methods The volatile components in different processed products of A.fructus were detected and analyzed by gas chromatography-mass spectrometry(GC-MS)based on multivariate statistical analysis.After OPLS-DA analysis,the different components were screened under the conditions of VIP＞1.5 and P＜0.05 and were qualitatively searched using the NIST 11 spectral library.Results A total of 49 different components were identified,with 14 components only changing in the seed mass and 22 components changing in the peel.The content of camphor could be significantly reduced in the seed mass after A.fructus was processed and the content of bornyl acetate significantly increased in the peel of frying A.fructus.Salt frying had a great influence on the alkanes in A.fructus,and ginger processing did not only increase the volatile components in ginger,which reflected the complexity of the processing mechanism.Conclusion At present,the specific processing mechanism is not clear,but the experimental results provide theoretical data for the "detoxification and efficiency enhancement" effect of A.fructus processing,reflecting the scientific nature of the processing,enriching the processing theory of A.fructus,and providing a reference for further in-depth research on the activity of different processed products of A.fructus.

Objective To investigate the causal relationship between walking pace(WP)with interver-tebral disc degeneration(IVDD)and low back pain(LBP)by using two-sample Mendelian randomisation(MR)analysis method.Methods A genome-wide association study database of WP,IVDD and LBP was ob-tained,and single nucleotide polymorphisms(SNP)strongly associated with exposure were obtained as the in-strumental variables.The two confounders of smoking and sedentary were conservatively removed,and the MR analyses were performed by inverse variance weighting(IVW),weighted median,and MR-Egger methods to assess the causal relationship between WP with IVDD and LBP.The consistency and accuracy of results were ensured by heterogeneity,diversity tests,MR-PRESSO and negative control.Results The I VW results showed a significant negative correlation between WP and IVDD(OR=0.348,95％CI:0.183-0.661,P=0.001)and vice versa(OR=0.972,95％CI:0.953-0.992,P=0.007).Meanwhile there was also a significant negative correlation between WP and LBP(OR=0.214,95％CI:0.119-0.385,P＜0.001),but no causal re-lationship was found between LBP and WP.Conclusion Faster WP could effectively prevent the occurrence of IVDD and LBP,and IVDD may contribute to the occurrence of slow walking.

Objective To study the causal association between depression with knee,hip,hand,spine and early osteoarthritis by using the Mendelian randomization(MR).Methods The public genome-wide asso-ciation study(GWAS)database was used to select the data of depression and OA(knee,hip,hand,spine and early stage),which had the precise diagnostic standards.When the exposure was set as depression and the out-come was multiple OA,it was positive analysis,and vice versa.The inverse variance weighted(IVW)served as the main outcome indicator,which was combined with the simple weighting model,MR-Egger intercept method,weighted median and weighted mode methods for conducting the results judgment.The analysis re-sults conducted the pleiotropy,heterogeneity,outliers and sensitivity tests to judge the robustness of the re-sults.Results The forward direction analysis:depression showed the causal association with knee OA(IVW:P=0.010,OR=1.65,95％CI:1.13-2.41),spine OA(IVW:P＜0.001,OR=2.92,95％CI:1.70-5.01)and early OA(IVW:P=0.002,OR=5.23,95％CI:1.83-14.90),no causal association was found between depression with hip OA and hand OA.The reverse direction analysis:the causal association between knee OA,hip OA and hand OA with depression was undefined.Due to the small number of instrumental variables(IVs)extracted from the spine and early OA at the time of exposure,the causal association between the two and depression was not investigated from the reverse direction analysis.The above analyses in the tests of plei-otropy,heterogeneity,outliers and sensitivity did not found the obvious abnormality,therefore the results were reliable.Conclusion There are significantly unidirectional positive causal association between depression with knee O A,spine OA and early OA.

Objective To investigate the safety and efficacy of photodynamic therapy (PDT) for malignant obstruction of the biliary tract. Methods We retrospectively analyzed the clinical data of patients with malignant biliary obstruction treated by PDT in our medical center. On the basis of different treatment plans, the patients were categorized into the photodynamic only group and the combined treatment group, in which additional interventional operations, targeted therapy, or immunotherapy were arranged. The alterations in liver function, duration of biliary patency, and postoperative complications that occurred within one month were closely monitored in both groups. Results A total number of 19 patients were enrolled in this study. The technical success rate of PDT was 100%. The deterioration of liver function was not observed in any patients within one month after PDT. Within a maximum of 17.7 months follow-up, the patency rates of the biliary tract were 100.0%, 89.5%, 72%, and 64% at 1, 3, 6, and 12 months after the procedure, respectively. The mean biliary patency time was 6.9±0.8 months (95%CI: 5.2-8.7 months). Specifically, the biliary patency times for Bismuth type Ⅲ and Ⅳ were 7.5±1.1 and 6.1±1.3 months, respectively. The biliary patency time was around 3.3±0.7 months in the photodynamic only group and 7.9±0.9 months in the combined treatment group (P=0.017). Conclusion PDT for Bismuth Ⅲ-Ⅳ malignant biliary obstruction is safe and effective. Moreover, the period of biliary patency is greatly extended when PDT is combined with systemic therapy.

Objective To evaluate the value of percutaneous transhepatic angioplasty in treatment of portal vein stenosis (PVS) after pediatric liver transplantation.Methods The data of 8 pediatric patients with PVS after liver transplantation were retrospectively evaluated.All cases were confirmed by portal vein angiography,and were treated with percutaneous transluminal angioplasty and/or percutaneous transluminal stent angioplasty.The effect of endovascular interventional therapy in 8 cases was analyzed.Results A total of 12 times of 8 patients received endovascular interventional therapy.The success rate was 66.67％ (8/12).The clinical success rate of the first treatment was 62.50％ (5/8).Three cases were treated with balloon dilation after the first balloon dilation,and there was no recurrence of PVS after operation in 2 cases.After the treatment of balloon dilation,stent angioplasty was performed in 1 case.There were no complications related to treatment in 8 cases.Conclusion Endovascular interventional treatment is a safe and effective way for PVS after pediatric liver transplantation.

Objective To study CT-guided localization of additional pulmonary nodules with microcoils prior to video-assisted thoracoscopic surgery (VATS) resection in patients with suspected lung cancer.Methods Eleven patients suspected lung cancer underwent preoperative microcoils localization towards additional small pulmonary nodules.The head of microcoil was pinpointed adjacent to the target nodule while its end tail remained above the visceral pleura.VATS were performed within 24 hours, and comprehensive assessments were conducted according to surgical and pathological outcomes of primary and additional lesions, and suitable surgical processes were followed.Results All 11 localizing pulmonary nodules (4-15 mm in diameter) were successfully removed after VATS, 9 microcoils'' end tails of which were placed above visceral pleural surface.There were no serious complications related with localizing procedure.Other 16 lesions including 11 primary ones were resected.The surgical and pathological outcomes for lung lesions were utterly assessed.Conclusion Microcoil preoperative localization provides helpful orientation for complete resection and assessment of multiple pulmonary lesions in patients with suspected lung cancer.
