ABSTRACT

SUMMARY OBJECTIVES To evaluate the epidemiological characteristics of acute pancreatitis (AP) and explore potential relationships between these factors and severity. METHODOLOGY Data-sets of 5,659 patients with AP from health statistics and the Information Center of Jiangsu province, between 2014 and 2016, were analyzed. A self-organizing map (SOM) neural network was used for data clustering. RESULTS Biliary acute pancreatitis (BAP) (86.7%) was the most frequent etiological factor. A total of 804 (14.2%) patients had severe acute pancreatitis (SAP). The mean age of patients was 53.7 + 17.3 (range 12~94y). Most of the AP patients were married (75.4%); 6% of mild /moderately severe AP (MAP/MASP) patients were unmarried, which was less than SAP patients (P=0.016). AP patients with blood type AB in the general population (8.8%) was significantly lower than that of AP cases (13.9%) (P=0.019) and SAP cases(18.7%) (P=0.007). The number of AP patients in southern Jiangsu was much higher than that in northern Jiangsu province, especially in Nanjing (1229, 21.7%). The proportion of acute alcoholic pancreatitis (AAP) in the north of Jiangsu (Xuzhou 18.4%) was much higher than that in southern Jiangsu (Suzhou 2.6%). The whole sample was divided into five classes by SOM neural network. If BAP patients were male, old, divorced, and blood type AB or B, they were more likely to develop SAP. Middle-age, unmarried or divorced male patients with blood type B/AB who suffered from HAP or AAP were also more likely to develop SAP. CONCLUSIONS The number of unmarried patients with MAP/MASP was smaller than that of SAP. Blood types AB and B were more frequent in AP, especially in SAP. The differences between southern Jiangsu and northern Jiangsu, in number of AP patients and the proportion of AAP, were significant. In class I and class IV, the ratio of SAP was much higher than in other classes and the whole sample.

ABSTRACT

Abstract Objective: Implantable cardioverter-defibrillator has become the first-line therapy for prevention of sudden cardiac death. Controversial results still exist regarding the effectiveness of implantable cardioverter-defibrillator (ICD) in non-ischemic heart failure. Methods: The PubMed, Embase, and Cochrane Central databases were searched for randomized trials comparing implantable cardioverter-defibrillator in combination with medical treatment versus medical treatment for non-ischemic heart failure. The primary endpoint was incidence of all-cause death. We derived pooled risk ratios with fixed-effects models. Results: Five studies enrolling 2573 patients were included. Compared with medical treatment, implantable cardioverter-defibrillator with medical treatment was associated with a significantly lower risk for all-cause mortality (Risk ratio: 0.83; 95% confidence interval 0.71 to 0.97). Conclusion: Compared with medical treatment only, implantable cardioverter-defibrillator in combination with medical treatment reduces all-cause mortality.

ABSTRACT

ABSTRACT Aim: The role of low-intensity extracorporeal shock wave therapy (LI-ESWT) in erectile dysfunction (ED) is not clearly determined. The purpose of this study is to investigate the short-term efficacy and safety of LI-ESWT for ED patients. Materials and Methods: Relevant studies were searched in Medline, Embase, Cochrane Library, China National Knowledge Infrastructure (CNKI), WANFANG and VIP databases. Effective rate in terms of International Index of Erectile Function-Erectile Function Domain (IIEF-EF) and Erectile Hardness Score (EHS) at about 1XSmonth after LI-ESWT was extracted from eligible studies for meta-analysis to calculate risk ratio (RR) of effective treatment in ED patients treated by LI-ESWT compared to those receiving sham-treatment. Results: Overall fifteen studies were included in the review, of which four randomized controlled trials (RCTs) were for meta-analysis. Effective treatment was 8.31 [95°/o confidence interval (CI): 3.88-17.78] times more effective in the LI-ESWT group (n=176) than in the sham-treatment group (n= 101) at about 1 month after the intervention in terms of EHS, while it was 2.50 (95% CI: 0.74-8.45) times more in the treatment group (n= 121) than in the control group (n=89) in terms of IIEF-EF. Nine-week protocol with energy density of 0.09mJ/mm2 and 1500 pluses seemed to have better therapeutic effect than five-week protocol. No significant adverse event was reported. Conclusion: LI-ESWT, as a noninvasive treatment, has potential short-term therapeutic effect on patients with organic ED irrespective of sensitivity to PDE5is. Owing to the limited number and quality of the studies, more large-scale, well-designed and longterm follow-up time studies are needed to confirm our analysis.

ABSTRACT

<p><b>OBJECTIVE</b>To investigate the effects of local administration of Zoledronate solution on the tooth movement and periodontal ligament.</p><p><b>METHODS</b>Orthodontic tooth movement of upper first molar was performed in 42 rats with coil spring. Zoledronate solution was injected into the palatal submucosal area adjacent to the left upper first molar in experimental group 3 days prior to the use of the appliance. In control group, same amount of 0.9% NaCl solution was injected into the palatal submucosal area adjacent to the left and right upper first molar. The injection was applied every third day. The application of mesial force lasted 0.3, 7, 14, 21 days respectively. After the rats were sacrificed, the distance of tooth movement was measured. Sections were stained and then observed with microscope.</p><p><b>RESULTS</b>1. The distance of tooth movement in the experimental group was significantly smaller than that in the control group. 2. The number of osteoclast on the pressure side in the experiment group was significantly smaller than that in the control group through the experimental period, but there was no distinct difference between experimental group and control group (except for 14 days) for the number of odontoclast in interradicular area. 3. The osteoclasts and odontoclasts were the main target cell of Zoledronate in periodontal tissue.</p><p><b>CONCLUSIONS</b>Zoledronate may be a useful agent for anchorage control and reducing the number of osteoclast on pressure side of alveolar bone.</p>

ABSTRACT

Periodontal ligament stem cells(PDLSCs) are not only the crucial type of cells in maintaining dynamic homeostasis and wound repair of periodontal tissues but also the basis for novel therapeutic strategy for periodontal regeneration.Although possessing the excellent proliferation and differentiation ability,PDLSCs behave differently under various conditions representative of several influential factors.Understanding of these influential factors will help us to exploit more about PDLSCs,and more importantly,lead a new modality in treating periodontal diseases based on stem cells.Here we review multiple important factors affecting function of PDLSCs and propose its use in future regenerative therapy of periodontal defects.

ABSTRACT

Objectives:To evaluate the effect of different teeth arrangement methods on the masticatory efficiency of complete dentures.Methods: Three complete dentures for each of ten edentulous patients were made respectively by using maxillary teeth arrangement,mandibular teeth arrangement and comprehensive teeth arrangement methods.After three months of wearing,the masticatory efficiency of the three complete dentures was tested by light absorption method,and was compared to that of dentulous subjects.Results:The masticatory stroke and masticatory efficiency in denture wearing group were fewer and weaker than those in dentulous group in either bilateral mastication or unilateral mastication. Good masticatory efficiency was gained after three months of wearing the complete dentures made by the three different teeth arrangement methods.There were no significant difference in the masticatory stroke and masticatory efficiency of complete dentures made by mandibular teeth arrangement and comprehensive teeth arrangement methods,but they were both higher than those made by maxillary teeth arrangement method.Conclusions:The complete dentures made by mandibular teeth arrangement method and comprehensive teeth arrangement method are feasible for restoration of masticatory efficiency of endentulous patients.
