Objective To summarize the application of endovascular treatment of the acute ruptured intracranial aneurysms with the new Trufill detachable coil system.Methods Thirty five patients with the acute ruptured intracranial aneurysms were treated with DCS or DCS Orbit within 72 hours. Results All 35 cases were successful with compact embolization in 29 aneurysms,95% in 3 aneurysms,90% in 2 aneurysms,80% in 1 anearysm.One case hemorrhaged during operation and 1 case had thrombosis after operation,but with good prognosis of both.One case died of pneurmonia.Thirty cases achieved clinic follow-up 1 to 15 months after operation with only one rebleeing.Sixteen cases achieved DSA follow-up 3 to 12 months after the operation.Partial recurrence of the occluded aneurysm was shown in 1 case.Conclusions Trufill DCS or DCS Orbit is a safe,reliable and effective therapy for the endovascular treatment of intracraranial aneurysms.

Objective To investigate the preliminary experience of mechanical thrombectomy with a tri-axial system of the Solitaire AB stent through a Neuro delivery catheter to treat intracranial large artery occlusion. Methods A tri-axial system was used to deliver the Solitaire AB stent through a Neuro delivery catheter to provide intracranial aspiration in close proximity to the stent. This technique was used in 1 case of acute middle cerebral artery occlusion and 1 case of acute basilar artery occlusion. Results Successful revascularization was achieved in these 2 cases. Thrombolysis in cerebral infarction (TICI)score was 3. The clot length of acute middle cerebral artery occlusion was 3 cm and the modified Rankin Scale (mRS)score of this case was 3 at 90 days follow-up. Another patient with acute bilateral vertebral occlusion was revealed successful recanalization by angiography. Conclusion The results suggest that this technique of a tri-axial system used of the Solitaire stent through a Neuro delivery catheter can effectively retrieve clots from the occlusive artery and minimize the chance of antegrade blood flow dislodging the thrombus.

OBJECTIVETo investigate the effect of total flavonoids of astragalus on the expression of endoplasmic reticulum chaperone, calumenin and connecxin 43 (CX43) in suckling mouse myocardium with myocarditis caused by coxsackievirus B3 (CVB3).
METHODSThe primary culture of suckling mouse myocardium cells were randomly divided into control group, CVB3 infected group and total flavonoids of astragalus group. Firstly, to confirm the identity of the suckling mouse myocardium, α-SMA was monitored by immunohistochemistry method. Then the protein expression changes of endoplasmic reticulum chaperone-glucose regulatory protein 78 ( GRP78), calumenin and CX43 were detected by Western blot.
RESULTS(1) Compared with that of the control group, the GRP78 expression level in CVB3 infected group was improved, the expression levels of calumenin and CX43 were all reduced. (2) Compared with that of CVB3 infected group, GRP78 expression level was decreased, and the expression levels of calumenin and CX43 were increased in total flavonoids of astragalus group.
CONCLUSIONCVB3 infection may cause endoplasmic reticulum stress of rat myocardium cells by increasing the expression of GRP78 and decreasing the expression of calumenin and CX43. On the other hand, total flavonoids of astragalus can reduce the expression of GRP78 and increase the expression of calumenin and CX43.The results of this experiment may be closely related to the effects of anti-arrhythmia with viral myocarditis caused by CVB3.

To investigate the cardioprotective effect of formononetin (FMN) on no-reflow (NR) after myocardial ischemia-reperfusion and its molecular mechanism based on integrated pharmacology and experimental verification, firstly, human breast cancer MCF-7 cells and myocardial NR rats were used to confirm the estrogenic activity and the effect of alleviating NR of FMN, respectively. Male SD rats were divided into Sham, NR, FMN (20 mg·kg-1) and sodium nitroprusside (SNP, 5.0 mg·kg-1) groups, which were administered once a day for one week, the experiment was approved by the Ethics Committee of Tianjin University of Traditional Chinese Medicine (TCM-LAEC2019095).

OBJECTIVETo find a convenient and exact method for evaluating acrosome reaction in human spermatozoa.
METHODSThe semen of the normal male was mixed and then divided into 6 groups. Coomassie brilliant blue (CBB) staining, chlortetracycline (CTC) fluorescence staining and acid phosphatase (ACP) detection were used for morphological observation and data analysis of the acrosome status of the human sperm treated with or without progesterone.
RESULTSThere were obvious morphological differences between the acrosome-reaction and acrosome-intact spermatozoa in CBB staining and CTC fluorescence staining, and significant differences were observed between the experimental and control spermatozoa by the three methods (P < 0.05).
CONCLUSIONAll the three methods can be used to assess acrosome reaction in human spermatozoa, but Coomassie brilliant blue (CBB) staining is much more convenient and stable.

OBJECTIVETo explore a new access for internal rigid fixation of mandibular mid-and-low condylar fracture.
METHODS16 patients of unilateral mid-and-low condylar fractures were treated with a 2cm mini-retromandibular approach. The subcutaneous tissues superficial to the superficial muscular aponeurotic system (SMAS) were dissected forward that parallel to the masseter muscle fiber bundles, aiming to the fracture. After exposing the fracture, the fracture segments were reduced and fixed under sufficient exposure.
RESULTSCorrect anatomic reduction and occlusion were achieved in all cases. Additionally, all patients showed normal articular function and the surgical scars were barely visible.
CONCLUSIONThe transmasseter approach by retromandibular access is one of the feasible methods for curing mid-and-low condylar fracture, which minimizeing the risk of facial nerve injury and reducing the visible scars.

The purpose of this study was to establish real-time based methods for detection of NPM1 gene mutation in acute myeloid leukemia (AML). Primers/probes were designed according to the clustered region of NPM1 mutations on exon 12. Two real-time PCR assays, including high resolution melting curve (HRM) and allele-specific PCR (AS-PCR), were developed and clinically evaluated with 89 AML samples, which were parallelly detected by capillary electrophoresis (CE) and sequencing. The results showed that a total of 17 mutation-positive samples were detected, including type A (15 cases), type B (1 case) and type Nm (1 case). HRM assay could detect all mutant types, and the analytical sensitivity was around 5%. In contrast, AS-PCR assay detected only 95% mutant types, but its sensitivity was as high as 0.01%. It is concluded that considering the characteristics of each method as well as the clinical evaluation results, HRM may be used for screening of NPM1 mutations at diagnosis, while the AS-PCR can be used for the MRD quantification during follow-up.

OBJECTIVETo observe characteristics of acupuncture in improvement of sleep quality in the patient of insomnia.
METHODSForty-six cases of primary insomnia were randomly divided into an observation group (n = 24) and a control group (n = 22). The observation group were treated by the needling method for regulating mental activity, with Baihui (GV 20), Shenting (GV 24), Shenmen (HT 7) selected as main points; the control group were treated with oral administration of Estazolam. The therapeutic effects and scores of Pittsburgh Sleep Quality Index Scale before and after treatment were compared between the two groups.
RESULTSThe total effective rate was 83.3% in the observation group and 72.7% in the control group, the observation group being better than the control group (P < 0.05). Estazolam was better than acupuncture treatment in prolonging sleeping time, and the acupuncture treatment was better than the control group in the improvement of somnipathy and the increase of daytime functional state (P < 0.05).
CONCLUSIONAcupuncture treatment has advantages of improving somnipathy and increasing daytime functional state.
