The solids acceleration length was investigated in a cold dense transport bed （0.10 m-IDx17 m-height） with three kinds of Silica sand. The solids circulation rate （Gs） was up to 954 kg/（m2s）. The effects of operating conditions, particle properties, and riser structures on the solids acceleration length were investigated under high Gs conditions, with the effect of riser height non-negligible. The solids acceleration length increased with the increase of the riser height. Based on the experimental data, an empirical correlation was proposed to predict the solids acceleration length. Predictions of the correlation were in good agreement with the experimental data in this work and those from the literature over a wide range of Gs （18~954 kg/（m2s））.

Patients who received endovascular therapy (EVT) for acute ischemic stroke with large vessel occlusion (AIS-LVO) and large-scaled core infarct volume in the time window were analyzed. Literature data were reviewed. Results showed that although EVT is the first choice to AIS-LVO, patients often have poor prognosis. Alberta stroke program early CT score (ASPECTS) based on computerized tomography angiography source image (CTA-SI) can reflect the real cerebral perfusion more truly, and it can assess the size of core infarct more quickly and accurately, thus enabling to judge prognosis.

Objective: To analyze the effect and advantages in analgesia and sedation of butorphanol tartrate combined with dexmedetomidine in severe cerebral hemorrhage for patients with mechanical ventilation. Methods: 120 patients with severe cerebral hemorrhage requiring analgesia and sedation were randomly selected and divided into two groups: the control group (dexmedetomidine treatment group) and the test group (dexmedetomidine combined with butorphanol tartrate). Two groups of patients with different drugs were analyzed. Results: The average dose of dexmedetomidine (microgram) and the total adverse events (Times) in the test group were significantly lower than those in the control group within 48 hours (P < 0.05);The dose of Butorphanol in the test group was small, and the patients in the control group used other opioid analgesics to pump more significantly. Conclusion: Using butorphanol tartrate combined with dexmedetomidine can achieve the same sedative effect and enhance the analgesic effect as using dexmedetomidine alone with less dose of dexmedetomidine, and the clinical effect is significant. It also solves the problem that adverse reactions such as blood pressure change and bradycardia are easy to occur when using large dose of dexmedetomidine and the infusion speed is fast in clinical application, and significantly reduces the incidence of adverse reactions. It is worthy of clinical application.

Case Reports in Clinical Medicine 2020年第8期9卷 223-227页

作者： Gang yang shaojun yang Junjie Lv Chenbing Wang Department of Neurosurgery Zhuji Affiliated Hospital of Shaoxing University Shaoxing China

Background: Patients with severe hypertensive brainstem hemorrhages have poor prognoses if they only receive conservative medical management. In contrast, aggressive operative interventions may decrease the morbidity and mortality in such patients. These operative treatments include craniotomy for evacuation of the hematoma, stereotactic positioning, and neuronavigational-guided hemorrhage puncture and drainage. Here, we report a novel and relatively simple procedure to achieve satisfactory outcomes in a patient with a brainstem pontine hemorrhage. Case Presentation: A 53-year-old man who was diagnosed with brainstem pontine hemorrhage. On hospital day 6, he underwent CT-guided, virtual stereotactic puncture and catheter drainage of this brainstem pontine hemorrhage. Medical treatments were continued after this procedure. On postoperative day 16 (hospital day 22), the patient was discharged from the hospital, awake and able to answer questions appropriately. Muscle strengths were grades V and IV for the left and right extremities, respectively. The patient was continued with active rehabilitation and achieved a Barthel index of 85 points at one month after the percutaneous drainage procedure. Conclusion: CT-guided, virtual stereotactic percutaneous transcranial puncture and catheter drainage for brainstem pontine hemorrhages has obvious potential advantages and offers a possible alternative to achieve the best outcomes with minimal operative trauma compared to open microcraniotomy.

OBJECTIVE: To investigate the efficacy of Cigu Xiaozhi pill(慈菇消脂丸, CGXZ) on non-alcoholic steatohepatitis(NASH)-associated lipoapoptosis through the stress-activated c-Jun N-terminal kinase(JNK)/stress-activated protein kinase signalling ***: Sixty male Sprague-Dawley rats were randomly divided into the following groups(10 rats each): blank control, model, low-dose CGXZ,medium-dose CGXZ, high-dose CGXZ, and positive control(treated with SP600125, a JNK inhibitor).The NASH model was established and the histomor-phological characteristics of haematoxylin and eosin-stained liver tissues were examined under a light microscope. Cell apoptosis in liver tissues was assessed via terminal deoxynucleotidyl transferase d UTP nick-end labelling assay. In addition, the m RNA and protein expression levels of p-JNK,p-c-Jun, caspase-8, Fas, and Fas-L were determined via fluorescence-based quantitative real-time PCR,immunohistochemical and Western blot ***: Histopathological examination of the liver showed that the model rats had moderate-to-severe steatosis with infiltration of inflammatory cells as well as significantly higher expression levels of the p-JNK, p-c-Jun, caspase-8, Fas, and Fas-L proteins, compared with those in the blank control group(P < 0.01). Hepatic lobules of the rats in the treatment groups showed significantly reduced vacuolar degeneration and steatosis as well as alleviated inflammatory cell infiltration. The high and medium-dose CGXZ groups exhibited significantly lower m RNA and protein expression levels of p-JNK, p-c-Jun, caspase-8, Fas, and Fas-L, compared with those in the model group(P < 0.05 or P <0.01).CONCLUSION: CGXZ pill inhibited the onset of hepatocyte apoptosis by regulating the expression of p-JNK, p-c-Jun, caspase-8, Fas, and Fas-L, thereby exerting therapeutic effects against NASH.

Background: Bilateral frontal lobes cerebral contusion and laceration is one unique brain injury in neurosurgery department. It is characteristic of recessive attacking and develops quickly. The unilateral cerebral falx incision is a new minimally invasive surgery that can solve bilateral frontal lobes cerebral contusion and laceration in one surgery. However, it has some limitations in removal of contralateral frontal hematoma and hemostasis due to the limited field of view under the microscope. The unilateral bone window cerebral falx incision of bilateral frontal lobes cerebral contusion and laceration under a neuroendoscopy can acquire a good illumination and field of view. This is beneficial to complete removal of contralateral hematoma, effective hemostasis and retaining brain tissue functions to the maximum extent. Case Presentation: The patient, a 55-year-old man, was hospitalized for “consciousness disorder by 12 h because of car accident”. Physical Examination: Coma, GCS score of E1V2M5, bilateral pupil diameter of 2 mm, presence of light response, contusion of scalp at the left top, peripheral dysphoria and bilateral Bartter syndrome negative. The patient has a history of non-traumatic cerebral stroke 3 years ago. Head CT: Longitudinal fracture of frontal parietal occipital bone, bilateral frontal lobes contusion and laceration, subarachnoid hemorrhage. Diagnosis: Bilateral frontal lobes contusion and lace
