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.

Objective:To analyze the clinical efficacy of treatment of cement dislodgement after vertebral augmentation for osteoporotic vertebral fractures.Methods:A retrospective study was conducted to analyze the data of 13 patients who had been treated at Department of Orthopaedics, The First Affiliated Hospital of Soochow University for cement dislodgement after vertebral augmentation for osteoporotic vertebral fractures from July 2013 to July 2022. There were 4 males and 9 females, with an average age of (76.5±8.6) years and a T value of bone mineral density of -3.3±0.6. By the CT and MRI features of cement dislodgement, their conditions fell in 4 types: cement loosening in situ (4 cases), anterior cement moving (6 cases), anterior cement moving with posterior bone mass moving (2 cases), and posterior cement moving (1 case). They were treated by percutaneous vertebroplasty (3 cases), pedicle screw fixation combined with bone graft fusion and decompression (7 cases), and conservative therapy (3 cases). The curative effects for surgical patients were evaluated by comparing their visual analogue scale (VAS), Oswestry dysfunction index (ODI) and cobb angle of kyphosis at preoperation, 1 week and 1 month postoperation, and the last follow-up, and Frankel grading for nerve injury as well. The curative effects for patients undergoing conservative treatment were evaluated by observing their symptoms.Results:This cohort was followed up for 7 (5, 12) months after treatment. The VAS scores [5.0 (4.0, 5.0) points, 3.0 (2.0, 3.0) points, and 3.0 (2.0, 3.0) points] in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value [8.5 (8.0, 9.0) points] ( P<0.05); the VAS scores at 1 month postoperation and the last follow-up were also significantly improved compared with that at 1 week postoperation ( P < 0.05), but there was no significant difference between the last follow-up and 1 month postoperation ( P > 0.05). The ODIs (50.6%±4.2%, 37.8%±4.5%, and 29.3%±5.6%) in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value (93.2%±3.6%), showing significant differences in pairwise comparisons ( P<0.05). The cobb angles [10.0 (9.0, 11.0)°, 9.0 (9.0, 11.0)°, and 10.0 (9.0, 12.0)°] in the 10 surgical patients at 1 week and 1 month postoperation and the last follow-up were significantly improved compared with the preoperative value [12.5 (11.0, 14.0)°] ( P<0.05) , but there was no statistically significant difference between the time points after operation ( P>0.05). The Frankel grading was significantly improved in the 6 patients with nerve injury after operation. Of the 3 patients undergoing conservative treatment, the symptoms were cured in one, showed no change during follow-up in one, and aggravated in one. Conclusion:Surgical treatment can significantly relieve pain, improve spinal dysfunction and repair nerve injury in patients with bone cement dislodgement after vertebral augmentation.

Objective:To establish the common carotid artery aneurysm models of Wallstent double stent overlapping implantation in miniature pigs, and evaluate the safety and effectiveness of this procedure by observing the imaging and pathological changes.Methods:Sidewall aneurysm and fusiform aneurysm models in Bama miniature pigs were established surgically and 2 Wallstent stents were overlapped and implanted in situ. Aneurysm healing immediately after surgery and during 8 weeks of follow-up were evaluated according to 2D-DSA by O'Kelly-Marotta (OKM) grading scale and Kamran scale; degrees of stent adhesion immediately after surgery and status of stent endothelialization and aneurysm healing at 2, 4, and 8 weeks after surgery were observed by high resolution C-arm CT(HR-CBCT) and optical coherence tomography (OCT); and the changes of stent endothelialization were evaluated by comparing the HR-CBCT and OCT results with histopathology at 8 weeks after surgery. Perioperative adverse events were recorded.Results:After successful establishment of common carotid artery aneurysm models (including 4 sidewall aneurysms and 4 fusiform aneurysms with average diameter of [11.0±2.8] mm) in 8 miniature pigs, a total of 16 Wallstent stents (2 in each aneurysm) were implanted across the aneurysmal neck, with a technical success rate of 100%. No serious complications such as acute stent thrombosis, or aneurysm rupture and bleeding were observed in the perioperative period. The 2D-DSA immediately after surgery showed obvious intracranial contrast agent retention in 6 patients (1 patient in grading 1, 3 in grading 2, and 2 in grading 3) and aneurysm occlusion in 2 patients (grading 4). Eight weeks after follow-up, all 8 aneurysms had complete occlusions (grading 4); and 2 experimental pigs had in-stent restenosis, with stenosis rates of 52% and 67%, respectively. HR-CBCT and OCT immediately after surgery and during follow-up indicated that the stent metal braid was gradually covered by proliferating intima, with disappeared aneurysm. The cause of in-stent restenosis in 2 experimental pigs was local intima hyperplasia resulted from poor stent adhesion, and pathological findings indicated that the intima hyperplasia was mainly composed of smooth muscle cells and fibrous connective tissues.Conclusion:In animal models, Wallstent stent overlapping implantation is safe and effective in common carotid aneurysms, but intraoperative adverse adhesion of overlapping stent should be avoided.

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 provide reference for improving TCM treatment of pulmonary nodule. METHODS ：The experience of famous TCM doctors in the TCM treatment of pulmonary nodule was searched by computer ，the formulations of the cases were sorted out ，and the data were recorded into the TCMISS V 2.5 for data analysis ，and the medicine frequency was counted. Apriori algorithm and association rules were used for statistical analysis of core combination of formulations （support degree was 16，confidence degree was 0.65）. Inner core combination and new combination were extracted according to the entropy clustering method of complex system （correlation was 6，penalty was 2）. RESULTS ：A total of 25 literatures were input ，including 64 formulations in total ，166 medicinal materials. For the prescriptions of pulmonary nodule ，the frequency of single ingredient from high to low was Bolbostemma paniculatum ，Glycyrrhiza uralensis ，Astragalus membranaceus ，Prunella vulgaris ，Ostrea gigas，Angelica sinensis ，Pinellia ternate ，Ligusticum chuanxiong ，Mori Corlex ，etc. The main compatibility of the drug model is to invigorate Qi ，dissipate phlegm ，invigorate Qi and activate blood circulation ，and promote Qi and softness ，such as “G. uralensis，B. paniculatum ”“A. membranaceus ，B. paniculatum ”“A. membranaceus ，G. uralensis ”，etc；10 core combinations of the drug were found out ， such as Begonia fimbristipula-Rhodiola rosea-Bupleurum Chinense ， Cervus elaphus Clematis chinensis-Buffalo Horn，etc. There were 5 new prescriptions ，i.e. B. fimbristipula-R. rosea-B. chinense-Setaria italic ，C. elaphus-C. chinensis-Buffalo Horn-French chalk ，A. sinensis-L. chuanxiong-Morus alba- Mori Corlex -P. vulgaris-Ganoderma lucidum ，Hedyotis diffusa-Prunus persica-Trichosanthes kirilowii-Achyranthes bidentata-Eupolyphaga sinensis- Cinnamomi Ramulus ，A. bidentata-E. sinensis-Ephedra sinica-Curcuma aromatica-Curcuma longa-Concretio silicea . CONCLUSIONS ：Most modern doctors believe that the interaction of phlegm and blood stasis is the main pathogenesis of pulmonary nodule ，and the treatment is mainly based on the treatment of lung ，spleen，liver and kidney ，focus on the elimination of symptoms and phlegm ，the elimination of blood stasis and the soft and hard treatment ，pay attention to the weak body of the patient. TCM treatment of pulmonary nodule has a good prospect.

In eukaryotes, protein phosphorylation is specifically catalyzed by numerous protein kinases (PKs), faithfully orchestrates various biological processes, and reversibly determines cellular dynamics and plasticity. Here we report an updated algorithm of Group-based Prediction System (GPS) 5.0 to improve the performance for predicting kinase-specific phosphorylation sites (p-sites). Two novel methods, position weight determination (PWD) and scoring matrix optimiza-tion (SMO), were developed. Compared with other existing tools, GPS 5.0 exhibits a highly com-petitive accuracy. Besides serine/threonine or tyrosine kinases, GPS 5.0 also supports the prediction of dual-specificity kinase-specific p-sites. In the classical module of GPS 5.0, 617 individual predic-tors were constructed for predicting p-sites of 479 human PKs. To extend the application of GPS 5.0, a species-specific module was implemented to predict kinase-specific p-sites for 44,795 PKs in 161 eukaryotes. The online service and local packages of GPS 5.0 are freely available for academic research at http://gps.biocuckoo.cn.

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.

Objective To investigate the effect of liraglutide combined with glargine insulin in treating the patients with newly diagnosed type 2 diabetes mellitus (T2DM).Methods Sixty-one cases of newly diagnosed T2DM in the endocrinology department of Affiliated Chaozhou Central Hospital of Southern Medical University,from August 2014 to December 2015 were selected and divided into two groups according to the random number table.The observation group (29 cases) was treated with liraglutide combined with glargine insulin and the control group (32 cases) was given the intensive insulin therapy.The curative effects before and after treatment were analyzed and compared between the two groups.Results The fast plasma glucose(FPG),postprandial 2 h blood glucose(PPG),glycosylated hemoglobin(HbA1c),fasting C peptide(FCP),postprandial 2 h C peptide(PCP),insulin resistance index(HOMA-IR),blood lipid indicators and body mass index after 12-week treatment were decreased in the treatment and follow up periods,while pancreatic β cell function index (HOMA-β) and HDL-C were increased,indicating that the two kinds of treatment method all were effective.The effect onset in the observation group was faster,the above indexes after 4-week treatment were significantly improved compared with before treatment.The above indexes after 4-,12-week treatment in the observation group were significantly superior to those in the control group,the difference was statistically significant(P<0.05).Conclusion Liraglutide combined with glargine insulin has better effect in the aspects of reducing blood glucose,regulating blood lipid,decreasing the body mass and islet function recovery than the intensive insulin treatment and is worthy of clinical promotion and application.

Objective: To investigate the efficacy and safety of the new investigational drug pegylated interferon α-2b (Peg-IFN-α-2b) (Y shape, 40 kD) injection (180 µg/week) combined with ribavirin in the treatment of patients with genotype 1/6 chronic hepatitis C (CHC), with standard-dose Peg-IFN-α-2a combined with ribavirin as a positive control. Methods: A multicenter, randomized, open-label, and positive-controlled phase III clinical trial was performed. Eligible patients with genotype 1/6 CHC were screened out and randomly divided into Peg-IFN-α-2b(Y shape, 40kD) group and Peg-IFN-α-2a group at a ratio of 2:1. The patients in both groups were given oral ribavirin for 48 weeks in addition and then followed up for 24 weeks after drug withdrawal. Abbott Real Time HCV Genotype II was used to determine HCV genotype, and Cobas TaqMan quantitative real-time PCR was used to measure HCV RNA level at 0, 4, 12, 24, 48, and 72 weeks. Adverse events were recorded in detail. The primary efficacy endpoint was sustained virological response (SVR), and a non-inferiority test was also performed. Results: A total of 561 patients with genotype 1/6 CHC were enrolled, among whom 529 received treatment; 90.9% of these patients had genotype 1 CHC. The data of the full analysis set showed that SVR rate was 69.80% (95% CI 65.00%-74.60%) in the trial group and 74.16% (95% CI 67.73%-80.59%) in the control group (P = 0.297 0). The data of the per protocol set (PPS) showed that SVR rate was 80.63% (95% CI 76.04%-85.23%) in the trial group and 81.33% (95% CI 75.10%-87.57%) in the control group (P = 0.849 8), and the 95% CI of rate difference conformed to the non-inferiority standard. The analysis of the PPS population showed that of all subjects, 47.9% achieved rapid virologic response, with a positive predictive value of 93.8%. The incidence rate of adverse events was 96.30% in the trial group and 94.94% in the control group, and the incidence rate of serious adverse events was 5.13% in the trail group and 5.06% in the control group. Conclusion In the regimen of Peg-IFN-α combined with ribavirin for the treatment of genotype 1/6 CHC, the new investigational drug Peg-IFN-α-2b(Y shape, 40 kD) has comparable clinical effect and safety to the control drug Peg-IFN-α-2a.

Objective To develop kinesthetic and visual imagery questionnaires applicable to Chinese stroke survivors and evaluate their test-retest reliability,inter-rater reliability and internal consistency.Methods The English version of a kinesthetic and visual imagery questionnaire (KVIQ) was translated into Chinese using wellaccepted questionnaire translation procedures.Thirty stroke survivors were each assessed twice using two versions of the translation (the KVIQ-20 and the KVIQ-10) by two experienced raters with an interval of 7 days between the tests.The test-retest reliability,inter-rater reliability and internal consistency of the visual imagery score (visual imagery subscale),the kinesthetic imagery score (kinesthetic imagery subscale) and the total scores for the KVIQ-20 and KVIQ-10 versions were analyzed.Results The test-retest coefficients,the inter-rater reliability correlation coefficients and Cronbach's alphas for the KVIQ-20 version ranged from 0.879 to 0.945,from 0.894 to 0.936 and from 0.867 to 0.919,respectively.The corresponding measurements for the KVIQ-10 vcrsion were 0.914 to 0.953,0.852 to 0.900 and 0.827 to 0.878.Conclusion Both the KVIQ-20 and KVIQ-10 Chinese instruments have shown good testretest and inter-rater reliability and good internal consistency in assessing stroke survivors.Either is an effective tool for assessing their motor imagery ability.
