Objective:To summarize the imaging features of severe unilateral transverse sinus and sigmoid sinus thromboses, and evaluate the efficacy and safety of intravascular interventional therapy in them.Methods:Thirty-seven patients with severe unilateral transverse sinus and sigmoid sinus thromboses clinically mainly manifested as intracranial hypertension and accepted endovascular intervention in Department of Interventional Radiology, First Affiliated Hospital of Zhengzhou University from June 2012 to September 2022 were chosen; their clinical data were retrospectively analyzed and imaging features were summarized. Short-term efficacy was evaluated according to blood flow restoration degrees and pressure gradient reduction in the occlusive sinus and modified neurological symptoms before and after endovascular intervention. Hospitalized complications were observed; safety and long-term efficacy were evaluated according to postoperative clinical follow-up and imaging results 6-12 months after endovascular intervention.Results:(1) Preoperative brain MRI and (or) CT showed different degrees of swelling of the brain tissues, with the affected side as the target; mixed signals/density shadow could be seen in the blocked transverse sinus and sigmoid sinus; venous cerebral infarction or post-infarction cerebral hemorrhage could be combined in some patients. MRV, CTV and DSA showed poor or completely occluded transverse sinus and sigmoid sinus while normal in the contralateral side; obvious thrombus filling-defect was observed in the occluded venous sinus after mechanical thrombolysis. (2) Occlusive sinus blood flow was restored in all patients after endovascular intervention, and pressure gradient of the occlusive segment decreased from (16.6±3.3) mmHg before to (2.8±0.8) mmHg after endovascular intervention. Before discharge, clinical symptoms of all patients were significantly improved (modified Rankin scale [mRS] scores of 0 in 30 patients, 1 in 5 patients, 2 in 1 patient and 3 in 1 patient), and 2 patients had unilateral limb movement disorder (muscle strength grading III and IV, respectively). All patients received clinical follow-up for (9.6±3.0) months. At the last follow-up, neurological function obviously improved compared with that before endovascular intervention, without new neurosystem-related symptoms (mRS scores of 0 in 30 patients, 1 in 6, and 2 in 1 patient). In 34 patients received MRV or DSA follow-up, 28 had complete recanalization of occlusive sinus and 6 had partial recanalization, without obvious stenosis or recurrent occlusion.Conclusions:Severe unilateral transverse sinus and sigmoid sinus thrombosis can cause local intracranial venous blood stasis, and then cause "increased regional venous sinus pressure", which is manifested as unilateral brain tissue swelling and even venous cerebral infarction or post-infarction cerebral hemorrhage. Early diagnosis and endovascular intervention can obviously improve the prognosis of these patients, enjoying good safety.

Pathological insulin resistance (IR) is closely related to gestational diabetes mellitus (GDM) and adverse pregnancy outcomes in women with GDM. Increasing studies have investigated the efficacy of IR indices, such as quantitative insulin sensitivity index, homeostasis model assessment of insulin resistance, triglyceride-glucose index and sex hormone-binding globulin, in predicting GDM and related complications in recent years. This article reviews the research progress in the above topics.

Objective:To implement an intervention with community-dwelling middle-aged and elderly people through a new science promotion approach, and to evaluate changes in the level of bone health awareness.Methods:From April 2017 to June 2017, 200 community-dwelling middle-aged and elderly people aged 50 years and over were randomly included.They were divided into the intervention group receiving a new science promotion intervention(n=100, with 50 males and 50 females)and the control group(n=100, with 50 males and 50 females). Baseline and follow-up assessments of bone health awareness were performed before and after the one-year intervention.A questionnaire survey on preferences for different types of science promotion articles in WeChat accounts was conducted.Differences in scores for intervention effects before and after intervention were compared between the two groups.Potential influencing factors for the scale score were examined by a multi-factor analysis.Results:After one year of intervention, scores for intervention effects were higher in the intervention group than in the control group( P<0.001). In the intervention group, scores were higher after intervention than before intervention( P<0.001). In the control group, scores after follow-up were slightly higher than those at baseline(29.4±11.4 vs.27.9±10.1, P<0.001). The increase in scores before and after intervention was greater in the intervention group than in the control group( P<0.001). Baseline score, group designation, history of drinking and diabetes impacted the scores in middle-aged and elderly women, while other factors did not.Most middle-aged and older people preferred texts illustrated with pictures, and older people were more receptive to videos. Conclusions:The new science promotion method is beneficial to bone health management, can improve bone health awareness in middle-aged and elderly people.

Objective To investigate the clinical value of antibody D5F3 and Survivin in patients with non small cell lung cancer.Methods 200 paraffin embedded specimens of patients with non small cell lung cancer tested by RT-PCR(including EML4-ALK mutant and wild type)from October 2012 to June 2014 were selected.The gene protein expression were tested by ALK new antibody D5F3 and the sensitivity and specificity were compared by negative and positive(+～3+).ResultsTest results show(+)the coincidence rate is 15.78％,(+ +)the coincidence rate is 27.27％and(+ + +)compliance rate was 87.5％,the difference was statistically significant(P<0.05).The expression of Survivin protein in NSCLC tissues was correlated with clinicopathological features.The positive rate of Survivin protein expression was correlated with the degree of differentiation(P<0.05),but not with other clinical and pathological features,with the decrease of differentiation,the positive rate of Survivin protein expression was significantly increased.Conclusion D5F3 and Survivin antibodies are highly sensitive and specific in patients with NSCLC,with the screening value,save social resources,for the majority of patients with lung cancer services.

Objective To compare the safety and efficacy of direct and remedial rotational atherectomy in the treatment of heavily calcified coronary artery lesions.Methods We retrospectively reviewed 58 patients admitted in the Shanghai Chest Hospital and Liaocheng People Hospital from May 2012 to July 2015 who had received stent implantation and rotational atherectomy.The 58 patients were divided into two groups which were the direct atherectomy group (n =27) and the remedial atherectomy group (n =31).General clinical date,lesion and procedural characteristics,intraoperative complications,in-hospital and follow-up MACCE were compared between the two groups.Results There were no differences between the two groups in general clinical date intraoperative complications,amount of contrast agent used,proceduraltime,rates of in-hospital and follow-up MACCE.Nevertheless,compared with the direct artherectomy group,the remedial group had more number of balloon dilations during procedure [3 (1,5) vs.2 (1,2),P ＜ 0.001] and higher peak cardiac troponin levels [1.1 (0.3,3.0) μg/L vs.0.5 (0.1,2.3) μg/L,P =0.032].Conclusions Remedial rotational atherectomy with drug-eluting stent had the same safety and efficacy as direct atheretomy with drug-eluting stent in treating patients with heavily calcified coronary lesions.It is reasonable and safe to transform routine PCI to remedial rotational atherectomy when the 2.0 mm semi compliant balloon or/and 2.5 mm non-compliant balloon cannot pass through or dilate the lesions.

Abnormal uric acid metabolism is closely associated with the development and progression of nonalcoholic fatty liver disease (NAFLD). This article describes the relationship between uric acid and the prevalence and severity of NAFLD, and point out that uric acid metabolic disorders directly affect the development and progression of NAFLD through complicated pathways such as insulin resistance, oxidative stress, direct influence on the expression of lipid synthetase, and inflammatory response. Control of uric acid is expected to become one of the multimodality therapies for NAFLD.

Objective To observe the effect of Jianpi Buxue Decoction on the protein expression of neurokinin 1 receptor (NK1R) and CD34 in C57BL/6 mice of lung cancer after chemotherapy, and to explore the improvement of chemotherapy-induced nausea and vomiting and myelosuppression treated with Jianpi Buxue Decoction. Methods Forty C57BL/6 mice were transplanted with Lewis lung cancer cells in the armpit of left anterior limb after being fed for 7 days, and then were randomly divided into lung cancer group, model group, and high-, middle- and low-dose Chinese medicine groups. Model group and Chinese medicine groups were injected intraperitoneally with cyclophosphamide (80 mg/kg) for one day. Lung cancer group and model group were given normal saline. Chinese medicine groups were administered with high-, middle- and low-dose of Jianpi Buxue Decoction (25, 12.6, 6.25 g/kg respectively) for 14 days. After the modeling, all of the mice were sacrificed, and then the brains and spleens were sampled. Western blotting method was used to detect the protein expression of NK1R and CD34. Results Compared with lung cancer group, the protein expression of cerebral NK1R and splenic CD34 in the model group was increased significantly ( P<0.01) . Compared with the model group, the protein expression of NK1R in mice brain tissues of high-, middle- and low- dose Jianpi Buxue Decoction groups was decreased significantly (P<0.01) , while the protein expression of CD34 in spleen tissues of middle-and low-dose Jiangpi Buxue Decoction groups was increased obviously ( P<0.05) . Conclusion Jianpi Buxue Decoction has an effect on down-regulating the protein expression of NK1R in brain tissues and on up-regulating the protein expression of CD34 in spleen tissues of C57BL/6 mice with lung cancer after chemotherapy, indicating that Jianpi Buxue Decoction probably can relieve chemotherapy-induced nausea and vomiting, and can improve the myelosuppression after chemotherapy.

Objective To evaluate the utility of multi-slice computed tomography (MSCT) in assessing acute non-reperfused myocardial infarct size. Methods Seven domestic pigs (mean weight 17.3 ± 1.9 kg) underwent ligation of the distal left anterior descending artery to establish a model of acute myocardial infarction (MI). MSCT and triphenyltetrazolium chloride (TTC) staining were performed two hours later. The following data were acquired and analyzed:MI volume (%), CT values of the infarcted region, left ventricular cavity and normal cardiac tissue at various scanning time-points (1, 5, 10, 15, 20 min after contrast injection). Results Using MSCT, the overall MI volume showed a time-dependent decrease, with a reduction of 28.87%after 20 min. The greatest reduction occurred at the 5 min time-point. In TTC staining, MI volume was 9.87%± 2.44%. When MI size, as determined by MSCT, was compared with that by TTC staining in Bland-Altman plots, there was a better agreement at 5, 10, and 15 min time-points at 1 and 20 min. Conclusions The study indicates that double-phase scanning examination using MSCT is a useful tool to assess MI size, and the optimal late-phase scanning time-point set within 5-15 min of contrast injection.
