OBJECTIVE@#To investigate the clinical effect of aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban for lower extremity venous thrombosis after total knee arthroplasty and the influence on hypercoagulation.@*METHODS@#Seventy-three patients of knee osteoarthritis with lower extremity venous thrombosis after total knee arthroplasty (KOA) were randomly divided into an observation group (37 cases, 2 cases dropped off) and a control group (36 cases, 1 case dropped off). The patients in the control group took orally rivaroxaban tablets, 10 mg a time, once a day. On the basis of the treatment as the control group, the aconite-isolated moxibustion was applied to Yongquan (KI 1) for the patients of the observation group, once daily and 3 moxa cones were used in each treatment. The duration of treatment was 14 days in both groups. Before treatment and 14 days into treatment, the ultrasonic B test was adopted to determine the conditions of lower extremity venous thrombosis in the two groups. Before treatment, 7 and 14 days into treatment, the coagulation indexes (platelet [PLT], prothrombin time [PT], activated partial prothrombin time [APTT], fibrinogen [Fib] and D-dimer[D-D]), the blood flow velocity of the deep femoral vein and the circumference of the affected side were compared between the two groups separately, and the clinical effect was evaluated.@*RESULTS@#Fourteen days into treatment, the venous thrombosis of the lower extremity was relieved in both groups (P<0.05), and that of the observation group was better than the control group (P<0.05). Seven days into treatment, the blood flow velocity of the deep femoral vein was increased compared with that before treatment in the observation group (P<0.05), and the blood flow rate in the observation group was higher than that in the control group (P<0.05). Fourteen days into treatment, PT, APTT and the blood flow velocity of the deep femoral vein were increased in the two groups compared with those before treatment (P<0.05); and PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all reduced in the two groups (P<0.05). Compared with the control group 14 days into treatment, the blood flow velocity of the deep femoral vein was higher (P<0.05), PLT, Fib, D-D and the circumference of the limb (knee joint, 10 cm above the patella and 10 cm below the patella) were all lower in the observation group (P<0.05). The total effective rate was 97.1% (34/35) in the observation group, higher than 85.7% (30/35) in the control group (P<0.05).@*CONCLUSION@#Aconite-isolated moxibustion at Yongquan (KI 1) combined with rivaroxaban can effectively treat lower extremity venous thrombosis after total knee arthroplasty, relieve hypercoagulation, accelerate the blood flow velocity and alleviate swelling of the lower extremity in the patients with knee osteoarthritis.

Development of General Practice in Communities From the Perspective of Supply and Demand / 中国医学科学院学报

Objective To put forward suggestions for improving the scheme of general practice for functional communities from the perspective of supply and demand,guide the efficient use of the resources of general practice by the communities,and incorporate the general practice of communities into hierarchical diagnosis and treatment management. Methods In July 2021,stratified random sampling was employed to conduct the questionnaire surveys of the young and middle-aged (demand side) and the general practitioners (supply side),respectively.SPSS 20.0 was used for data analysis. Results The two sides had the same cognition about the main reasons for not signing a contract with a family doctor,which were the lack of knowledge about general practitioners and the lack of face-to-face communication opportunities.They had the same response about the form of services,with high acceptance of medical services via WeChat,outpatient consultation,and the internet.There were differences in service content between the two sides.The top three demands of the young and middle-aged were appointment registration and referral in superior hospitals,medication guidance,and massage,acupuncture,and moxibustion.The top service self-rated by general practitioners was personalized guidance and report interpretation of physical examination,and the bottom was massage,acupuncture,and moxibustion. Conclusions The general practice varies between the demand and supply sides.General practitioners should be encouraged to enter and learn functional communities and provide personalized services,thus improving the general medical service in functional communities.

Preparation and Application of Monoclonal Antibody Against Human von Willebrand Factor Propeptide / 中国实验血液学杂志

OBJECTIVE@#To develop monoclonal antibodies that can specifically recognize human von Willebrand factor (VWF) propeptide (VWFpp) in plasma, and establish a rapid and reliable method for the detection of VWFpp antigen in plasma by using the double-antibody sandwich ELISA with the obtained anti-VWFpp monoclonal antibody.@*METHODS@#The recombinant human VWFpp (D1 and D2 regions) protein expressed in eukaryotic cells was used as immunogen to immunize BALB/c mice with routine method, so as to obtain clones of fusion cells. After screening and identification, hybridoma cell lines secreting monoclonal antibodies against VWFpp were selected, and then double-antibody sandwich ELISA assay was used to construct VWFpp antigen detection kit for the determination of VWFpp in human plasma. The levels of VWFpp antigen in plasma of 12 leukemia patients who underwent bone marrow transplantation were dynamically detected.@*RESULTS@#Two hybridoma cell lines that can be subcultured continuously and secrete monoclonal antibodies against VWFpp were obtained and named SZ175 and SZ176 respectively. Identified by ELISA and Western blot, the antibodies could both specifically recognize VWFpp but couldn't recognize mature VWF (without propeptide). Based on the principle of double-antibody sandwich ELISA, monoclonal antibodies SZ175 and SZ176 were successfully made into a kit for detecting VWFpp antigen. The plasma VWFpp levels of leukemia patients before and after bone marrow transplantation were dynamically detected. The results showed that the plasma VWFpp levels of the patients after transplantation were significantly higher than those before transplantation.@*CONCLUSION@#Two monoclonal antibodies against VWFpp were successfully prepared, and a double-antibody sandwich ELISA detection kit for VWFpp antigen was constructed, which provides a powerful tool for further study on the biological function of VWFpp, the clinical diagnosis and classification of von Willebrand disease (VWD), and the prognostic monitoring of endothelial injury-related diseases.

We performed an extensively targeting metabolomic detecting using ultra-performance liquid chromatography-mass spectrometry (UPLC-MS/MS) to compare the secondary metabolites in Dang shen [Codonopsis pilosula (Franch.) Nannf.] from Shanxi and Gansu provinces. The findings showed that 161 secondary metabolites in 6 groups (phenolic acids, flavonoids, lignans and coumarins, alkaloids, terpenoids, others) were found from Dang shen in Changzhi city of Shanxi province and Dingxi city of Gansu province. There were 98 secondary metabolites which is differed significantly. In comparison to Dingxi city, 33 different secondary metabolites of Dang shen in Changzhi city had a greater relative content, whereas relative content of 65 different metabolites in Dingxi city was higher. Metabolic pathway enrichment analysis revealed that phenolic acids and flavonoids were significantly different in the secondary metabolites of Dang shen from different producing places. This may be one of the reasons for the difference in the quality of Dang shen in Shanxi and Gansu provinces. This work compared and analyzed the secondary metabolites of Dang shen from Dingxi city in Gansu province and Changzhi city in Shanxi province for the first time, which lays the foundation for further study on the quality of Dang shen.

Predictors of efficacy of corticosteroid switching from abiraterone plus prednisone to dexamethasone in patients with metastatic castration-resistant prostate cancer / 亚洲男科学杂志(英文版)

Corticosteroid switching can reverse abiraterone resistance in some patients with metastatic castration-resistant prostate cancer (mCRPC). Here, we investigated the potential biomarkers for predicting the efficacy of corticosteroid switching during treatment with abiraterone acetate (AA). We retrospectively analyzed 101 mCRPC patients receiving corticosteroid switching from West China Hospital and Sun Yat-Sen University Cancer Center between January 2016 and December 2018. All cases received AA plus prednisone as first-line therapy during mCRPC. Primary end points were biochemical progression-free survival (bPFS) and overall survival (OS). The risk groups were defined based on multivariate analysis. A total of 42 (41.6%) and 25 (24.8%) patients achieved 30% and 50% decline in prostate-specific antigen (PSA), respectively, after corticosteroid switching. The median bPFS and median OS on AA plus dexamethasone were 4.9 (95% confidence interval [CI]: 3.7-6.0) months and 18.8 (95% CI: 16.2-30.2) months, respectively. Aldo-keto reductase family 1 member C3 (AKR1C3) expression (hazard ratio [HR]: 2.15, 95% Cl: 1.22-3.80, P = 0.008) and baseline serum alkaline phosphatase (ALP; HR: 4.95, 95% Cl: 2.40-10.19, P < 0.001) were independent predictors of efficacy before corticosteroid switching in the multivariate analysis of bPFS. Only baseline serum ALP >160 IU l-1 (HR: 3.41, 95% Cl: 1.57-7.38, P = 0.002) together with PSA level at switch ≥50 ng ml-1 (HR: 2.59, 95% Cl: 1.22-5.47, P = 0.013) independently predicted poorer OS. Based on the predictive factors in multivariate analysis, we developed two risk stratification tools to select candidates for corticosteroid switching. Detection of serum ALP level, PSA level, and tissue AKR1C3 expression in mCRPC patients could help make clinical decisions for corticosteroid switching.

Qualitative evaluation of Forsythia suspensa by HPLC-PDA fingerprint combined with UFLC-Q-TOF-MS qualitative identification / 中国中药杂志

The analysis of Forsythia suspensa was performed on Waters Symmetry C18 column( 4. 6 mm×250 mm,5 μm) and mobile phase was methanol( A)-0. 1% formic acid aqueous solution( B) with the elution gradient. Column temperature was maintained at 30℃,and the flow rate was 1. 0 m L·min-1 with detection wavelength 265 nm. The HPLC-PDA fingerprint of F. suspensa was optimized.Chemical constituents in F. suspensa were analyzed by UFLC-Q-TOF-MS in positive and negative ion mode. The quality of 48 batches of F. suspensa from different habitats,processing methods and specifications was evaluated by similarity evaluation and cluster analysis.The 18 common peaks were confirmed. The similarity of F. suspensa from different habitats was more than 0. 98,and 56 chemical constituents were identified. Different processing methods had great influence on the quality of F. suspensa. Compared with boiled and direct drying,the quality of F. suspensa processed by sun-drying was obviously decreased. The similarity was about 0. 58. Different specifications of F. suspensa also had obvious distinction,and the similarity was about 0. 78. The effective components of grown F. suspensa,such as forsythoside A and phillyrin,were significantly reduced. The results of cluster analysis were basically consistent with the results of similarity evaluation. The establishment of fingerprint and the recognition of chemical pattern of F. suspensa can provide a more comprehensive reference for the quality control of herbs.

Comparison of diagnostic efficacy between transrectal and transperineal prostate biopsy: A propensity score-matched study / 亚洲男科学杂志(英文版)

This study compared the diagnostic efficacy of transrectal ultrasound (TRUS)-guided prostate biopsy (TRBx) and transperineal prostate biopsy (TPBx) in patients with suspected prostate cancer (PCa). We enrolled 2962 men who underwent transrectal (n = 1216) or transperineal (n = 1746) systematic 12-core prostate biopsy. Clinical data including age, prostate-specific antigen (PSA) level, and prostate volume (PV) were recorded. To minimize confounding, we performed propensity score-matching analysis. We measured and compared PCa detection rates between TRBx and TPBx, which were stratified by clinical characteristics and Gleason scores. The effects of clinical characteristics on PCa detection rate were assessed by logistic regression. For all patients, TPBx detected a higher proportion of clinically significant PCa (P < 0.001). Logistic regression analyses illustrated that PV had a smaller impact on PCa detection rate of TPBx compared with TRBx. Propensity score-matching analysis showed that the detection rates in TRBx were higher than those in TPBx for patients aged >- 80 years (80.4% vs 56.5%, P = 0.004) and with PSA level 20.1-100.0 ng ml-1 (80.8% vs 69.1%, P = 0.040). In conclusion, TPBx was associated with a higher detection rate of clinically significant PCa than TRBx was; however, because of the high detection rate at certain ages and PSA levels, biopsy approaches should be optimized according to patents' clinical characteristics.

Bladder maximum volume, bladder residual urine volume and urinary tract infection before and after treatment were compared, and the clinical efficacy was evaluated in the two groups.@*RESULTS@#The total effective rate in the observation group was 88.2% (30/34), which was better than 64.7% (22/34) in the control group (<0.05). The increase of bladder maximum volume and decrease of bladder residual urine volume in the observation group were significantly better than those in the control group (<0.01). At the 4th, 6th and 8th weeks for treatment, the improvement of urinary tract infection in the observation group was better than that in the control group (<0.05).@*CONCLUSION@#At the same time of bladder function training, herbal cake-separated moxibustion with new-type moxibustion device could improve urinary retention after spinal cord injury.

Prior switching to a second-line nonsteroidal antiandrogen does not impact the therapeutic efficacy of abiraterone acetate in patients with metastatic castration-resistant prostate cancer: a real-world retrospective study / 亚洲男科学杂志(英文版)

Even in the era of novel targeted agents, switching to a second-line nonsteroidal antiandrogen (NSAA) is still widely used in treating metastatic castration-resistant prostate cancer (mCRPC), especially in undeveloped countries. However, whether prior treatment with a second-line NSAA would impact the efficacy of abiraterone acetate (Abi) remains uncertain. In the current study, 87 mCRPC patients treated with Abi were analyzed. Among them, 21 were treated with a second-line NSAA (from bicalutamide to flutamide) before receiving abiraterone, while the remaining 66 received Abi directly. Therapeutic efficacy of Abi was compared between those with and without prior second-line NSAA using Kaplan-Meier curves, log-rank test, and Cox regression models. The therapeutic efficacy of Abi was similar between those with or without the prior switching treatment of flutamide, in terms of either prostate-specific antigen progression-free survival (PSA-PFS, 5.5 vs 5.6 months, P = 0.967), radiographic progression-free survival (rPFS, 12.8 vs 13.4 months, P = 0.508), overall survival (OS, not reached vs 30.6 months, P = 0.606), or PSA-response rate (71.4% [15/21] vs 60.6% [40/66], P = 0.370). This is the first time that the impact of prior switching of treatment to a second-line NSAA on the efficacy of Abi in mCRPC patients has been addressed. Our data support that, use of prior sequential bicalutamide and flutamide does not seem to preclude response to abiraterone, although larger cohort studies and, ideally, a randomized controlled trial are needed. These findings will facilitate doctors' decision-making in the treatment of mCRPC patients, especially for those with previous experience of switching NSAA second-line treatments in the clinic.
