Objective We determined the proportion of doctors in Haidian community participating in the training of secondary prevention of ischemic cerebrovascular diseases related knowledge and the knowledge level of doctors so as to make a new targeted training plan,and assessed the effect of the training.Methods We enrolled 80 doctors,who filled out the questionnaire on secondary prevention of ischemic cerebrovascular diseases related knowledge,from 22 Haidian community center from March to July in 2014 in Beijing.The primary outcome was the proportion of doctors with the training of secondary prevention of ischemic cerebrovascular diseases related knowledge and the improvement rate of new training.Results Seventy (87.5％) community doctors didn't accept ischemic stroke secondary prevention system training.The understanding of Chinese Ischemic Stroke Subclassification and three cornerstones of secondary prevention of ischemic stroke(anti-hypertention,anti-lipidemia,antithrombotic) after the training was significant improvement (20％ vs.82.5％,P ＜ 0.05;31.25％vs.90％,P ＜ 0.05),while according to different causes classification subtype the doctors could make corresponding strategies of secondary prevention of ischemic cerebrovascular diseases.The rates of all community risk factors identification,community health education,lifestyle intervention,antihypertension,aspirin use,statin use,hypoglycemic treatment were both above 60％ no matter before the training or after the trainig.Conclusion Our results suggest that the community doctors in Haidian District lack corresponding knowledge of ischemic stroke secondary prevention.Further training of ischemic stroke secondary prevention is needed.

Objective To explore the efficacy and safety of the resection of prostate-tangerine techniquewith 980 nm diode laser benign prostatic chyperplasia(BPH).Methods Data of 60 patients with highvloum BPH treated with the resection of prostate-tangerine technique with 980 nm diode laser were reviewed.The age of the patients were 65-89 years old,and mean prostate volume was 74.5± 13 ml.The mean operative time,blood loss were oberseved and recored,the international prostate symptom score(IPSS),quality of life score (QOL),maximum urinary flow rate(Qmax) and residual urine volume (PVR) were collected and analyzed.Results The 60 cases were safe during the perioperative period.The average operation time was (70.2± 16.9) min,and there was no obvious bleeding during the operation and no blood transfusion cases.The time of remove the transurethral catheter was 2-5 d,and the mean time was (2.4±0.3) d.Follow up 1-3 months after operation,a significant reduction in IPPS was reported (P =0.000),significant durable improvements in Qmax,PVR before operation(P=0.000).Conclusion Transurethral vaporization of 980 nm diode laser could be a safe and effective treatment modality for BPH.

OBJECTIVE: To investigate the diagnostic value of transcranial Doppler ultrasound in early stage cerebral arteriosclerosis. METHODS: We selected 50 patients with early cerebral arteriosclerosis as the disease group. At the same time we selected another 50 patients as a control group with no significant symptoms in the nervous system. By 2 MHz pulse Doppler probe through double-temporal windows and pillow windows Basilar artery (BA), the bilateral middle cerebral artery (MCA) was detected. In the TCD spectrum, we selected the spectrum of a single-family cardiac cycle, identified the starting point (ts), pulse-incisure point (ti), end point (te), and the peak velocity (tp), measured the time of the spectrum starting point to the peak velocity (Tp) and calculated the time required for the peak velocity in the share of ventricular systolic (Tp/Ti), the time required for the peak velocity in the share of the whole cardiac cycle (Tp/T). Tp, Tp/Ti and Tp/T were respectively named as time to peak velocity (TPV), peak-time index-1 (PTI-1) and peak-time index-2 (PTI-2). All data were analyzed by SPSS13.0. RESULTS: There was no significant difference in blood vessel velocity, PI, RI and S/D of BA and RMCA (P>0.05) between the control group and the disease group. Compared with the control group, TPV of the BA, LMCA and RMCA significantly extended, PTI-1 and PTI-2 of BA, LMCA and RMCA increased significantly in the disease group (P<0.01). In the disease group, there was no significant correlation between peak time index and PI, S/D (P>0.05). CONCLUSION TPV, PTI-1 and PTI-2 are sensitive indicators of early stage cerebral arteriosclerosis.

Objective To study the effect and mechanism of paeonol(PAE)on renal interstitial fibrosis in rats.Methods The rats were randomly divided into sham operation(Sham)group,unilateral ureteral obstruction(UUO)group,PAE low dose(PAE-L)group,PAE medium dose(PAE-M)group,PAE high dose(PAE-H)group and irbesartan(IRB)group.Except for the Sham group,the UUO model was established in other groups.Each group was given a corresponding intervention for two weeks.Serum creatinine(Scr),blood urea nitrogen(BUN),serum 8-hydroxydeoxyguanosine(8-OHdG)levels,renal tissue superoxide dismutase(SOD),glutathione peroxidase(GPX)activities,α-smooth muscle actin(α-SMA),type Ⅰ collagen(Col-Ⅰ),fibronectin(FN),silent information regulator 1(SIRT1),nuclear factor E2-related factor 2(Nrf2)protein expression were detected;observe pathological changes of kidney tissue and calculate collagen volume fraction(CVF).Results Compared with the UUO group,the serum levels of Scr,BUN,and 8-OHdG in each dose group of PAE were decreased,the activities of SOD and GPX in kidney tissue were increased,the positive expressions of α-SMA,Col-Ⅰ and FN in kidney tissue were decreased,and the protein expressions of SIRT1 and Nrf2 were increased.Masson staining showed a decrease of CVF in renal tissue(all P<0.05),and HE staining showed a different degree of improvement in pathological changes such as inflammatory cell infiltration and tubular dilatation in renal tissue;PAE improves renal interstitial fibrosis in rats in a dose-dependent manner(P<0.05),and the effect of large dose PAE on renal interstitial fibrosis in rats was similar to that of IRB.Conclusion PAE can alleviate UUO-induced rat renal interstitial fibrosis and oxidative stress,and improve rat renal function.And this mechanism may be related to the activation of the SIRT1/Nrf2 signaling pathway.

Objective:To explore the clinical application value of rapid next-generation sequencing (NGS) strategy based on targeted amplicon sequencing in the diagnosis of myeloid neoplasms.Methods:In this observational study, both rapid NGS and conventional NGS on the bone marrow or peripheral blood samples of 682 patients were prospectively performed from February 2021 to August 2022 in First Affiliated Hospital of Soochow University. The sequencing results were analyzed using the local Ion Reporter software and our lab′s self-built bioinformatics platform, respectively. The timeliness of the two sequencing platforms was compared, and the Kappa consistency test was used to evaluate the consistency between the two sequencing platforms. Patients aged between 18 and 59 years with newly diagnosed acute myeloid leukemia (AML) underwent screening by rapid NGS combining multiplex RT-PCR and in situ fluorescence hybridization technique within 72 hours, from whom high-risk patients according to European LeukemiaNet (ELN) 2017 were screened for individualized induction therapy.Results:In terms of timeliness, the median time from sample receipt to report issuance were 3 (2, 4) days and 13 (11, 15) days under rapid NGS and conventional NGS testing, respectively, with a statistically significant difference ( Z=?22.636, P<0.001). Among 682 specimens with a total of 1 507 variants, rapid NGS detected a total of 1 499 variants, with a detection rate of 99.5% and 674 cases were accurate, with an accuracy rate of 98.8%; the conventional NGS detected 1 506 variants, with a detection rate of 99.9% and 681 cases were accurate, with an accuracy rate of 99.9%. In 682 specimens, there were 181 negative and 501 positive, in which 8 cases were missed under rapid NGS, and 1 case was missed under conventional NGS. The kappa value was 0.967 by Kappa consistency test, and P<0.001, suggesting good consistency and consistency between the two NGS platforms. From February 2021 to July 2022, 286 patients who were rapidly diagnosed of AML contained 78 patients screened as the ELN 2017 adverse-risk category, including 42 patients enrolled, with age 39 (33, 52) years old. After one cycle of venetoclax combined with decitabine induction therapy, 78.6%(38/42) of the patients achieved composite complete remission. Among the rest 104 additional myeloid neoplasms, rapid NGS detected mutations in 80 patients, with a detection rate of 76.9%, among which 89.0%(215/242) of the variants could serve as the basis for the diagnostic classification, prognostic evaluation, and target therapy of myelodysplastic syndromes (MDS), myeloproliferative neoplasms (MPN), and myelodysplastic/myeloproliferative neoplasms (MDS/MPN). Conclusion:The rapid NGS based on targeted amplicon sequencing is in good consistency with conventional NGS, and shorters the diagnostic time, whose sensitivity and detection range meets the need for diagnostic classification, prognostic stratification, and target therapy of myeloid neoplasms.
