BACKGROUND: Controversy exists as to the optimal treatment approach for ostial left anterior descending (LAD) or ostial left circumflex artery (LCx) lesions. Drug-coated balloons (DCB) may overcome some of the limitations of drug-eluting stents (DES). Therefore, we investigated the security and feasibility of the DCB policy in patients with ostial LAD or ostial LCx lesions, and compared it with the conventional DES-only strategy. METHODS: We retrospectively enrolled patients with de novo ostial lesions in the LAD or LCx who underwent interventional treatment. They were categorized into two groups based on their treatment approach: the DCB group and the DES group. The treatment strategies in the DCB group involved the use of either DCB-only or hybrid strategies, whereas the DES group utilized crossover or precise stenting techniques. Two-year target lesion revascularization was the primary endpoint, while the rates of major adverse cardiovascular events, cardiac death, target vessel myocardial infarction, and vessel thrombosis were the secondary endpoints. Using propensity score matching, we assembled a cohort with comparable baseline characteristics. To ensure result analysis reliability, we conducted sensitivity analyses, including interaction, and stratified analyses. RESULTS: Among the 397 eligible patients, 6.25% of patients who were planned to undergo DCB underwent DES. A total of 108 patients in each group had comparable propensity scores and were included in the analysis. Two-year target lesion revascularization occurred in 5 patients (4.90%) and 16 patients (16.33%) in the DCB group and the DES group, respectively (odds ratio = 0.264, 95% CI: 0.093-0.752, P = 0.008). Compared with the DES group, the DCB group demonstrated a lower major adverse cardiovascular events rate (7.84% vs. 19.39%, P = 0.017). However, differences with regard to cardiac death, non-periprocedural target vessel myocardial infarction, and definite or probable vessel thrombosis between the groups were non-significant. CONCLUSIONS The utilization of the DCB approach signifies an innovative and discretionary strategy for managing isolated ostial lesions in the LAD or LCx. Nevertheless, a future randomized trial investigating the feasibility and safety of DCB compared to the DES-only strategy specifically for de novo ostial lesions in the LAD or LCx is highly warranted.

OBJECTIVE: To compare the therapeutic effect between Fanzhen Jieci (warming acupuncture plus fast needling) combined with conventional acupuncture and simple conventional acupuncture on discogenic sciatica. METHODS: A total of 76 patients with discogenic sciatica were randomized into a Fanzhen Jieci group and a conventional acupuncture group, 38 cases in each one. Conventional acupuncture was applied at Shenshu (BL 23), Dachangshu (BL 25), L₁-L₅ Jiaji (EX-B 2) and Huantiao (GB 30) on the affected side, etc. in the conventional acupuncture group. On the basis of the treatment in the conventional acupuncture group, Fanzhen Jieci was applied at L₁-L₅ Jiaji (EX-B 2) and Huantiao (GB 30) on the affected side in the Fanzhen Jieci group, i.e. warming acupuncture was applied at L₁-L₅ Jiaji (EX-B 2), and fast needling was applied at Huantiao (GB 30) on the affected side for a depth of 40-60 mm, so as to introduce a sensation of electric shock transmitting to lower limb, and then the needle was immediately withdrawn. The treatment was given once every other day, 3 times a week for 3 weeks in both groups. The visual analogue scale (VAS) score of leg and low back pain, the Oswestry disability index (ODI) score and the 36-item short form health survey (SF-36) score before and after treatment were compared between the two groups. RESULTS: Compared before treatment, the VAS scores of leg and low back pain and the ODI scores after treatment were decreased in both groups (P<0.001), the changes of the VAS scores of leg and low back pain in the Fanzhen Jieci group were larger than those in the conventional acupuncture group (P<0.05). After treatment, except for the role emotional and health transition scores, the various scores of SF-36 were increased compared before treatment in the Fanzhen Jieci group (P<0.01); except for the role physical, role emotional and health transition scores, the various scores of SF-36 were increased compared before treatment in the conventional acupuncture group (P<0.01). After treatment, the physical functioning, role physical, bodily pain, mental health and general health scores of SF-36 in the Fanzhen Jieci group were higher than those in the conventional acupuncture group (P<0.05). CONCLUSION Fanzhen Jieci combined with conventional acupuncture can effectively relieve the pain and improve the mental state in patients with discogenic sciatica, its therapeutic effect is superior to simple conventional acupuncture.

Positron emission tomography (PET) is a powerful non-invasive molecular imaging technique for the early detection, characterization, and "real-time" monitoring of disease, and for investigating the efficacy of drugs (Phelps, 2000; Ametamey et al., 2008). The development of molecular probes bearing short-lived positron-emitting radionuclides, such as ¹⁸F (half-life 110 min) or ¹¹C (half-life 20 min), is crucial for PET imaging to collect in vivo metabolic information in a time-efficient manner (Deng et al., 2019). In this regard, one of the main challenges is rapid synthesis of radiolabeled probes by introducing the radionuclides into pharmaceuticals as soon as possible before injection for a PET scan. Although many potential PET probes have been discovered, only a handful can satisfy the demand for a highly efficient synthesis procedure that achieves radiolabeling and delivery for imaging within 1-2 radioisotope half-lives. Only a few probes, such as 2-deoxy-2-[¹⁸F]fluoro-D-glucose (¹⁸F-FDG) and [¹⁸F]fluorodopa, are routinely produced on a commercial scale for daily clinical diagnosis (Grayson et al., 2018; Carollo et al., 2019).

In the present study, four new sesquiterpenoids, chimonols A-D (compounds 1-4), together with four known compounds (5-8) were isolated from the EtOAc extract of Chimonanthus praecox Link. The structures of these new compounds were elucidated on the basis of spectroscopic techniques (UV, IR, MS, and 1D and 2D NMR), and their absolute configurations were established by comparing experimental and calculated electronic circular dichroism (ECD) spectra. Compounds 1-8 were evaluated for antimicrobial activities and the minimum inhibitory concentrations (MICs) were determined by the broth microdilution method in 96-well culture plates. Compounds 1, 2, and 7 exhibited weak antibacterial effects for S. aureus (ATCC 6538), E. coli (ATCC 11775), and P. aeruginosa (ATCC 10145) with MIC values being 158-249 µg·mL. Compounds 3-7 showed activities against C. glabrata (ATCC 2001) and S. aureus (ATCC 43300) with MIC values being 128-197 µg·mL. Compounds 1-4 showed activity against S. aureus (ATCC 25923) with MIC values being 162-254 µg·mL. The present study provided a basis for future evaluation of these compounds as antibacterial agents.

To analyze the medication features and the regularity of prescriptions of traditional Chinese medicine in treating patients with Qi-deficiency and blood-stasis syndrome of chronic heart failure based on modern literature. In this article, CNKI Chinese academic journal database, Wanfang Chinese academic journal database and VIP Chinese periodical database were all searched from January 2000 to December 2015 for the relevant literature on traditional Chinese medicine treatment for Qi-deficiency and blood-stasis syndrome of chronic heart failure. Then a normalized database was established for further data mining and analysis. Subsequently, the medication features and the regularity of prescriptions were mined by using traditional Chinese medicine inheritance support system(V2.5), association rules, improved mutual information algorithm, complex system entropy clustering and other mining methods. Finally, a total of 171 articles were included, involving 171 prescriptions, 140 kinds of herbs, with a total frequency of 1 772 for the herbs. As a result, 19 core prescriptions and 7 new prescriptions were mined. The most frequently used herbs included Huangqi(Astragali Radix), Danshen(Salviae Miltiorrhizae Radix et Rhizoma), Fuling(Poria), Renshen(Ginseng Radix et Rhizoma), Tinglizi(Semen Lepidii), Baizhu(Atractylodis Macrocephalae Rhizoma), and Guizhi(Cinnamomum Ramulus). The core prescriptions were composed of Huangqi(Astragali Radix), Danshen(Salviae Miltiorrhizae Radix et Rhizoma) and Fuling(Poria), etc. The high frequent herbs and core prescriptions not only highlight the medication features of Qi-invigorating and blood-circulating therapy, but also reflect the regularity of prescriptions of blood-circulating, Yang-warming, and urination-promoting therapy based on syndrome differentiation. Moreover, the mining of the new prescriptions provide new reference and inspiration for clinical treatment of various accompanying symptoms of chronic heart failure. In conclusion, this article provides new reference for traditional Chinese medicine in the treatment of chronic heart failure.

OBJECTIVETo explore efficacy of imatinib for patients with chronic myeloid leukemia(CML) and its resistance-related factors during the treatment.

METHODSThe clinical data of 214 CML patients received imatinib were analyzed respectively in our hospital from April 2005 to December 2010. The therapy history and efficacy of regular follow-up and factors influencing drug resistance were analyzed. COX regression analysis was used to perform the univariate and multivariate analysis.

RESULTSUntil the end of follow up, thirty-one patients (14.5%) occurred drug resistance. One of them was in accelerated phase(AP), and two in blast phase(BP); 69.2% of patients achieved a complete cytogenetic response(CCyR), and 31.3% of patients achieved a major molecular response(MMR). COX analysis was performed in 207 chronic phase(CP) patients. Univariate analysis showed that the course of disease before treatment, the hemoglobin count, the white blood cell count, whether achieved CCyR or not and whether achieved MMR or not were the influencing factors for imatinib resistance. Multivariate analysis showed that whether achieved CCyR or not was the independent factor for drug resistance.

CONCLUSIONWhether achieved CCyR or not is an independent factor and also a protective factor for imatinib resistance in patients with CML.

OBJECTIVETo investigate the effects of clearing the Governor Vessel and refreshing the mind needling in neural development and remediation of children with cerebral palsy.

METHODSA total of 200 cases of children with cerebral palsy were randomly assigned to the treatment group (100 patients) and the control group (100 patients). The treatment group was given the combined therapy of acupuncture and rehabilitation training, and the chosen acupoints were 13 points of the Governor Vessel, Shenshu (BL 23), Taixi (KI 3), Yanglingquan (GB 34), Zusanli (ST 36) and Sanyinjiao (SP 6), and points of refreshing the mind were also selected, which included puncturing Shenting (GV 24) toward Qianding (GV 21), puncturing Qianding (GV 21) toward Baihui (GV 20), puncturing Baihui (GV 20) toward Naohu (GV 17) and Sishencong (Ex-HN 1). The control group was only treated with rehabilitation training. A contrastive analysis of the therapeutic effect between acupuncture combined with rehabilitation training and rehabilitation training alone was made after a treatment course of 3 months. The Gross Motor Function Measure (GMFM) and Beijing Gesell Developmental Scale were adopted to assess the neural development and rehabilitation outcomes of the two groups. In addition, skull CT/MRI was adopted to evaluate the plerosis of injured cerebral nerve after treatment.

RESULTSThe total effective rate in treatment group was 87% (87/100), significantly higher than the 55% (55/100) in the control group. The children's development quotient (DQ) tested by Gesell Developmental Scale and scores tested by GMFM in the treatment group were obviously higher than those in the control group (P<0.01). The improving and curing rates presented by skull CT/MRI in the treatment group were higher than those in the control group (P<0.01).

CONCLUSIONSClearing the Governor Vessel and refreshing the mind needling could accelerate the recovery of injured brain nerve and the reconstruction of brain function. The acupuncture therapy could ameliorate both the motor development and cognitive development. On the other hand, the forward curative effect of acupuncture combined with rehabilitation training was significantly better than the rehabilitation training alone.
