Objective::Patients with untreated severe aortic regurgitation (AR) have a high risk of mortality. Transfemoral transcatheter aortic valve replacement (TF-TAVR) is a treatment option for AR; however, the safety and efficacy of this technique have not been sufficiently established. This study aimed to evaluate the clinical and anatomical variables correlating with device success of TF-TAVR using a self-expanding valve system for pure AR.Methods::Patients with pure native severe AR who underwent TF-TAVR using a self-expanding valve system were registered at 5 Chinese centers. The primary endpoint was device success at 1 month after TAVR. The secondary endpoint was the composite of major adverse cardiovascular events (MACE) at 6 months, including all-cause death, ischemic stroke, emergency conversion to cardiac surgery, and permanent pacemaker implantation. Echocardiography was used to analyze the left ventricular function before the TAVR procedure and during follow-up. Multivariable logistic regression and Cox regression analyses were performed to find relevant independent risk factors.Results::Between September 2019 and February 2022, 79 patients with AR were enrolled in the study. At 1 month, device success was achieved in 60 (75.9%) patients. By 6 months, 29 (36.7%) patients had MACE. Echocardiography revealed improved left ventricular function after TAVR. Multivariate regression analysis demonstrated that the Society of Thoracic Surgeons risk score (odds ratio 0.760, 95% confidence interval (CI): 0.584-0.989; P = 0.041) and annulus perimeter (odds ratio 0.888, 95% CI: 0.796-0.992; P = 0.035) were 2 predictors of device success. Moreover, annulus perimeter (<80.2 mm), but not Society of Thoracic Surgeons risk score, was associated with a significant reduction in MACE at 6 months (hazard ratio 2.223, 95% CI: 1.060-4.659; P = 0.028). Conclusions::TF-TAVR using a self-expanding valve system appears to be a safe and feasible treatment for patients with pure native severe AR, particularly those with a less enlarged annulus.

OBJECTIVE: To observe the clinical efficacy of acupoint injection combined with Vitalstim electrical stimulation for post-stroke dysphagia. METHODS: A total of 98 patients with dysphagia after first stroke were randomized into an acupoint injection group (35 cases, 2 cases dropped off), an electrical stimulation group (31 cases, 3 cases dropped off) and a combination group (32 cases, 3 cases dropped off). Injection of mecobalamin into Tunyan point, Vitalstim electrical stimulation and the combination of injection of mecobalamin into Tunyan point and Vitalstim electrical stimulation were applied respectively in the 3 groups, once a day, 10 times as one course, 2 courses were required. Before and after treatment, the tongue muscle thickness and video fluoroscopic swallowing study (VFSS) score were observed in the 3 groups. RESULTS: After treatment, the tongue muscle thickness was decreased (P<0.05), the VFSS scores were increased (P<0.05) compared with before treatment in the 3 groups, and the variation of tongue muscle thickness and VFSS score in the combination group was greater than the acupoint injection group and the electrical stimulation group (P<0.05). CONCLUSION Both acupoint injection of mecobalamin and Vitalstim electrical stimulation have therapeutic effect on dysphagia after stroke, and the two have synergistic effect.

Objective To investigate the protective effect of excretory-secretory protein (AES) from adult Trichinella spiralis on ovalbumin (OVA)-induced allergic rhinitis in mice. Methods Eighteen female BALB/c mice were randomly divided into three groups, including the blank control group (Group A), OVA-induced rhinitis group (Group B) and AES treatment group (Group C). Mice in Group A were given PBS. Mice in Group B were intraperitoneally injected with antigen adjuvant suspension for systemic sensitization, once every other day for seven times; then, local excitation was intranasally induced with 5% OVA solution once a day for seven times to establish a mouse model of allergic rhinitis. In addition to induction of allergic rhinitis, mice in Group C were given 25 μg AES at baseline sensitization and local excitation. Following the final challenge, mice were observed for 30 min in each group, and the behavioral score was evaluated. The serum levels of IFN-γ, IL-4, IL-5, IL-10 and TGF-β were determined using an enzyme-linked immunosorbent assay in mice, and the pathological changes of mouse nasal mucosa were observed under a microscope. Results There was a significant difference in the mouse behavioral scores among the three groups (F = 110.12, P < 0.01). The mouse behavioral score was significantly higher in Group B than in Group A (7.17 ± 0.75 vs. 1.33 ± 0.52, P < 0.01), and more remarkable pathological damages of mouse nasal mucosa were seen in Group B than in Group A, while the mouse behavioral score was significantly decreased in Group C than in Group B (P < 0.01), and the pathological damages of mouse nasal mucosa remarkably alleviated in Group C relative to Group B. There was a significant difference in serum IFN-γ level among the three groups (F = 7.50, P < 0.01) and the serum IFN-γ level in Group B was significantly lower than in group A and C (both P < 0.05). There were significant differences in serum IL-4 (F = 470.81, P < 0.01) and IL-5 levels (F =68.20, P < 0.01) among the three groups, and significantly greater serum IL-4 and IL-5 levels were detected in Group B than in Group A (P < 0.01), while significantly lower serum IL-4 and IL-5 levels were detected in Group C than in Group B (P < 0.01). There were significant differences in serum IL-10 (F = 174.91, P < 0.01) and TGF-β levels (F = 9.39, P < 0.01) among the three groups, and significantly greater serum IL-10 and TGF-β levels were seen in Group C than in Group B (both P < 0.05). Conclusion T. spiralis AES has a remarkable protective activity against OVA-induced allergic rhinitis in mice.

To explore famous veteran traditional Chinese medicine( TCM) doctors' medication rules in treating spermatorrhea based on the medical cases about spermatorrhea collected from Hundred TCM Clinical Doctors of Hundred Years in China and Proven Cases and National Medical Master Test Case. Researchers extracted such data as medicinal and therapies from these cases according to the inclusion and exclusion criteria. Then,Excle 2010,SPSS Clementine 12. 0 and SPSS 22. 0 were adopted respectively for frequency analysis,association rules analysis,cluster analysis and factor analysis. Cluster analysis was carried out by Ochiai algorithm of binary variable data,one of the systematic clustering methods. And principal component analysis was used for factor analysis. Finally,27 medical cases and 41 prescriptions were included in total. The frequency analysis showed that the most common therapy was the astringent therapy( n = 28),which was followed by the tonifying method,tranquilizing method,heat-clearing method,damp-dispelling method and Qiregulating method. The top three kinds of high-frequency traditional Chinese medicines were Poria,Ostreae Concha and Dioscoreae Rhizoma. The association rules analysis found out 11 association rules of medicine pairs,23 association rules of medicine combinations of the three kinds of herbs and 6 association rules of medicine combinations of five kinds of herbs. Among them,the representatives were Rubi Fructus→Fossilia Ossis Mastodi,Rehmanniae Radix Praeparata + Corni Fructus→Dioscoreae Rhizoma,and Pinelliae Rhizoma→Citri Reticulatae Pericarpium,which showed the therapeutic characteristics of astringing,tonifying the kidney and replenishing essence,fortifying the spleen and dispelling dampness. Moreover,7 medicine groups with relevance were extracted from the tree map generated by cluster analysis,including " Phellodendri Chinensis Cortex and Anemarrhenae Rhizoma" and " Angelicae Sinensis Radix,Rehmanniae Radix,Bupleuri Radix and Glycyrrhizae Radix et Rhizoma",which demonstrated the effects of nourishing Yin and purging fire,tonifying and soothing the liver. Besides,totally 12 common factors were obtained according to factor analysis,including 14 drug combinations,like " Amomi Fructus,Anemarrhenae Rhizoma and Phellodendri Chinensis Cortex" and " Nelumbinis Stamen,Moutan Cortex,Poria and Scrophulariae Radix",which indicated the compatibility characteristics of tonifying the spleen and purging fire,dispelling dampness and clearing heat. In conclusion,data mining techniques( including frequency analysis,association rules analysis,cluster analysis and factor analysis) were used to comprehensively analyze the famous veteran TCM doctors' medication rules in treating spermatorrhea,which was helpful for guiding the clinical practice of treating spermatorrhea in TCM.

BACKGROUND:At present,most of the experiments on the treatment of skin wound by mesenchymal stem cells have been performed in rats,mice and rabbits,while the research on skin wound treatment by canine bone marrow mesenchymal stem calls is less reported.OBJECTIVE:To observe the effect of canine bone marrow mesenchymal stem calls on skin wound healing.METHODS:A 3 cmx3 cm wound was made on the both sides of the scapula and buttocks of the dog,with the right side as experimental group and the left side as control group.After the wound was made,allogeneic canine bone marrow mesenchymal stem calls suspension was injected subcutaneously around the wound in the experimental group on the 1st and 3rd days.The control group was injected subcutaneously around the wound with mesenchymal stem call culture medium on the 1st and 3rd days after the wound was made.Wound healing was observed dynamically in both groups.RESULTS AND CONCLUSION:In the 1st week,there were pale yellow inflammatory substances in the wound of two groups indicating obvious inflammations.Compared with the control group,the inflammatory substances were fewer and the growth rate of the granulation tissue was faster in the experimental group.From the 2nd week until the wound healing,epithelialization on the wound became obvious following the formation of the granulation tissue,which was mainly displayed by the formation of fresh epithelial tissues from the surrounding to the wound center.The epithelialization time of the experimental group was earlier than that of the control group,and the wound area of the experimental group was smaller than that of the control group.In the 3rd week,the wound in the experimental group healed completely,and became smoother than that in the control group.The wound area of the experimental group was slightly smaller than that of the control group on the 8th and 12th days after cell transplantation,and the healing speed of the experimental group was slightly faster than that of the control group,but there was no significant difference between the two groups.Our findings indicate that the transplantation of canine bone marrow mesenchymal stem cells has the possibility or trend to promote skin wound healing.

Objective: To observe the synergistic effect of Qilan Capsules in the treatment of the patient with Qi-deficiency blood-stasis type of prostate cancer receiving androgen-deprivation therapy after castration. METHODS: This randomized controlled double-blind study included 246 cases of Qi-deficiency blood-stasis type of prostate cancer after castration, which were randomly divided into an experiment and a control group of equal number to be treated with Qilan Capsules + androgen-deprivation and placebo + androgen-deprivation, respectively. After 6 months of treatment, we compared the International Prostate Symptoms Scores (IPSS), TCM Symptoms Scores (TCMSS), maximal urine flow rate (Qmax), and the level of serum prostate-specific antigen (PSA) between the two groups of patients. RESULTS: Statistically significant differences were observed between the experiment and control groups in the syndrome classification-based efficacy (87.7% vs 67.9%, P <0.05) and total effectiveness rate (86.0% vs 71.6%, P <0.05). Compared with the baseline, the experiment group showed remarkable improvement after treatment in TCMSS (17.1±5.1 vs 8.3±4.0, P <0.05), IPSS (17.7±7.5 vs 11.4±4.6, P <0.05), and Qmax (［10.9±4.3］ ml/s vs ［14.7±3.7］ ml/s, P <0.05), and so did the control group (16.8±5.2 vs 11.5±5.2, 17.8±6.7 vs 14.6±5.8, and ［11.0±4.3］ ml/s vs ［12.0±4.1］ ml/s, P <0.05). The above three parameters were even more markedly improved in the former than in the latter group (P <0.05). However, there was no statistically significant difference between the two groups in the improvement of the PSA level after treatment (P >0.05). CONCLUSIONS Qilan Capsules can significantly enhance the effect of androgen-deprivation therapy in the treatment of Qi-deficiency blood-stasis type of prostate cancer after castration though cannot obviously improve the PSA level.

Objective: To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA. Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system. Results:The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (allP<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05). Conclusion: Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.
