Objective The purpose of the present study is to compare the pharmacokinetic and biodistribution properties of 99Tcm N-mercaptopyridine-N-oxide (99 Tcm N-MPO) with 99 Tcm-sestamibi (99 Tcm-MIBI) in normal dogs, and to investigate the potential of 99TcmN-MPO as a myocardial perfusion agent in canines with acute myocardial infarction. Methods Twelve healthy mongrel dogs were injected intravenously with 99TcmN-MPO (n = 6) or 99Tcm-MIBI (n = 6). Tracer kinetics in body fluids were determined by collecting blood of 1 ml via a femoral vein catheter at 30 s, 1,2,3,4,5, 10, 20, 30, 40, 60and 90 min post-injection (p. i.). The collected blood samples were weighed and counted for radioactivity in a γ-counter. Anterior and posterior planar γ-camera images were collected at 10, 20, 30, 60, 90, and 120 min after injection, with organ uptake quantified by region-of-interest (ROIs) analysis. For comparison, 99Tcm-MIBI was also evaluated in the same twelve dogs. Canine infarct models were set up by micro-invasive interventional embolization. SPECT images in the canine infarct model were collected 24 hours after myocardial infarction at 30 min and 60 min after the administration of 99Tcm N-MPO (n = 5) or 99Tcm-MIBI (n = 5). Results Both of 99Tcm N-MPO and 99Tcm-M1BI had a rapid blood clearance with less than 50% of initial radioactivity remaining at 1 min [99TcmN-MPO: (35. 77 ± 6. 31)% ID/mg ,99Tcm-MIBI (34. 46 ± 6. 83) % ID/mg] and less than 5% at 30 min p. i. [99Tcm N-MPO(3. 11 ± 1.44) % ID/mg,99Tcm-MIBI (2.93 ±0. 39)% ID/mg] . After injection, 99TcmN-MPO showed significant accumulation in the myocardium and prolonged retention. This rapid liver clearance of 99TcmN-MPO led to favorable heart-to-liver ratios, reaching values of 0. 54 ±0. 06 at 10 min, 1.02 ±0. 06 at 30 min, and 1.38 ±0. 06 at 60 min p. i.In contrast, the heart/liver ratio of 99Tcm-MIBI remained low at all time points (0. 46 ± 0. 03 at 10 min,0. 63 ±0. 03 at 30 min, and 0. 62 ± 0. 12 at 60 min p. i.). SPECT imaging studies in canines with acute myocardial infarction indicated that good visualization of the left ventricular wall and perfusion defects could be achieved at 30 min after administration of 99TcmN-MPO, but not 99Tcm-MIBI. Conclusion The combination of high heart uptake and rapid liver clearance makes 99TcmN-MPO a promising new radiotracer for myocardial perfusion imaging.

Glucagon-like peptide-1 (GLP-1) is a 30-amino acid peptide hormone that is mainly expressed in the intestine and hypothalamus. In recent years, basic and clinical studies have shown that GLP-1 is closely related to lipid metabolism, and it can participate in lipid metabolism by inhibiting fat synthesis, promoting fat differentiation, enhancing cholesterol metabolism, and promoting adipose browning. GLP-1 plays a key role in the occurrence and development of metabolic diseases such as obesity, nonalcoholic fatty liver disease, and atherosclerosis by regulating lipid metabolism. It is expected to become a new target for the treatment of metabolic disorders. The effects of GLP-1 and dual agonists on lipid metabolism also provide a more complete treatment plan for metabolic diseases. This article reviews the recent research progress of GLP-1 in lipid metabolism.

A 12-week-old baby with a vein of Galen aneurysmal malformation (VGAM) was successfully treated with performing transarterial microcatheter-directed embolization with Berenstein Liquid Coils and n-butyl cyanoacrylate in the feeding arteries. Post-procedure angiography showed a marked decrease of the blood flow into the dilated vein of Galen. Three months later, follow-up angiography showed that the vein of Galen aneurysmal malformation had totally disappeared, and the baby recovered very well without any sequelae. We report here on this interesting case along with a review of the relevant literature, and we aim to enhance physicians' awareness of the treatment for VGAMs.

TRESK is the most recently reported two-pore domain K+ channel, and different from other two-pore domain channels in gene, molecular structure, electrophysiological and pharmacological properties. Although the current knowledge of this potassium channel is inadequate, researches have demonstrated that TRESK is remarkablely linked to acute and chronic pain by activation of calcineurin. The fact that TRESK is sensitive to volatile anesthetics and localization in central nerve system implies that TRESK may play a very important role in the mechanism mediating general anesthesia. The further research of TRESK may contribute to explore the underlying mechanism of some pathological conditions and yield novel treatments for some diseases.

Objective:To explore the clinical effect and safety of intrinsic-nourishing exercise and oral Chinese medicine combined with conventional western medicine therapy in the treatment of perimenopause with insomnia.Methods:Prospective cohort study. A total of 60 perimenopause with insomnia visiting the Hebei Medical Qigong Hospital were enrolled as the research objects between June 2019 and June 2021. According to random number table method, they were divided into the control group and the observation group, 30 in each group. The control group was treated with oral estazolam tablets, while the observation group was treated with intrinsic-nourishing exercise combined with oral Chinese medicine on basis of the control group. All the patients were treated for 4 weeks as a course, and totally 2 courses. The levels of serum estradiol (E 2), FSH, and LH were detected by automatic chemiluminescence immunoassay analyzer. Pittsburgh sleep quality Index (PSQI) was used to evaluate sleep quality, and the quality of life was evaluated by the MOS 36-item Short Form Health Survey (SF-36). And the responsive rates, sleep quality, scores of TCM symptoms, and adverse reactions were compared before and after treatment. Results:The total response rate of observation group was significantly higher than that of the control group (90.0% vs. 66.7%; χ2=4.81, P<0.05). After treatment, PSQI scores of sleep quality, time to fall asleep, sleep duration, sleep efficiency, sleep disturbance, use of hypnotics, and daytime function in the observation group were significantly lower than those in the control group ( t=14.11, 12.49, 9.88, 13.54, 9.47, 14.11, 17.91, P<0.01). After treatment, the TCM symptom scores of insomnia with more dreams, waist and knee soreness, five upsets, fatigue and forgetfulness in the observation group were significantly lower than those in the control group ( t=9.51, 13.08, 16.17, 12.81, P<0.01). After treatment, the E 2 [(35.16±3.61) mmol/L vs. (31.06±3.12) mmol/L, t=4.71] in the observation group was significantly higher than that of the control group ( P<0.01), while the FSH [(69.61±6.04) U/L vs. (73.26±7.41) U/L, t=2.09], and LH [(32.21±3.35) U/L vs. (36.04±3.49) U/L, t=4.34] in the observation group were significantly lower than those in the control group ( P<0.05 or P<0.01). At 4 and 8 week after treatment, the SF-36 scores in the observation group were significantly higher than those in the control group ( t=6.30, 4.36, P<0.01). During treatment, 16.7% (5/30) adverse reaction happened in the observation group, while 10.0% (3/30) in the control group, but there was no statistical significant difference between two groups ( χ2=0.56， P=0.448). Conclusion:The intrinsic-nourishing exercise and oral Chinese medicine combined with conventional western medicine therapy can significantly improve clinical curative effect, improve sleep quality and TCM symptoms, regulate hormones and quality of life in perimenopause with insomnia.

OBJECTIVETo compare the difference of therapeutic effects between vessel pricking therapy and Prednisone for treatment of Henoch-Schonlein purpura nephritis.

METHODSSeventy cases of acute purpura nephritis syndrome were randomly divided into an observation group (40 cases) and a control group (30 cases). Patients in observation group were differentiated into sthenia and asthenia syndromes. Vessel pricking therapy was applied at Hegu (LI 4), Quchi (LI 11), Xuehai (SP 10) etc. by triangular needle for sthenia symptom; shallow needling was used at Pishu (BL 20), Shenshu (BL 23), Zusanli (ST 36) etc. by filiform needle. The control group was treated with oral admi-nidtration of Prednisone. The symptom score of TCM, 24 h urinary protein, red blood cell count of urinary sediment of both groups were observed before and after treatment and therapeutic effects were compared.

RESULTSThe total effective rate of 92.5% (37/40) in observation group was superior to that of 80.0% (24/30) in control group, and there was a significant difference between two groups (P < 0.05); the symptom score of TCM, 24 h urinary protein, red blood cell count of urinary sediment were all improved in both groups after treatment (all P < 0.05), and moreover, the improvement in observation group was superior to that of control group (all P < 0.05); after treatment, the symptom score of TCM of sthenia syndrome was lower than that of asthenia syndrome in observation group (P < 0.05).

CONCLUSIONVessel pricking therapy has a significant therapeutic effect for treatment of Henoch-Schonlein purpura nephritis, superior to that of oral administration of Prednisone, and the therapeutic effect is better for treating sthenia syndrome than for asthenia syndrome.

OBJECTIVETo identify the ETV6 gene rearrangement in patients with myelodysplastic syndromes (MDS) and explore its relationship with prognosis and disease stages.

METHODSETV6 rearrangement in 58 MDS cases were detected by conventional cytogenetics and Split-signal FISH. RT-PCR was used to detect 9p24-12p13 balance translocation with special designed primers ETV6F1/F2 and JAK2R1/R2. The relationship between ETV6 rearrangement and prognosis and disease staging in MDS patients was analyzed.

RESULTSETV6 rearrangement were found in 4 (6.9%) of 58 cases, among which ETV6/JAK2 fusion was identified by RT-PCR in 1 (1.7%) case. The mean follow-up duration was 12 months. All 4 patients (100%) with rearrangement transformed into acute leukemia, with a median survival time (MS) of 7 months; while 10 patients (17%) in the non-translocation group transformed to acute leukemia, with a MS of 28 months. In addition, all 4 patients (100%) with rearrangement were in advanced stage of MDS( RAEB), while 17 cases (31.5%) in non-rearrangement group were in that stage.

CONCLUSIONSETV6 rearrangement has higher expression rate (6.9%), and is closely associated with disease stage and prognosis in MDS.
