Effect of Yinqi Ointment on Wound Morphology and Growth Factor in Treating Diabetic Foot Ulcer

Objective: To investigate the effect of Yinqi ointment on wound morphology and growth factor in treating diabetic foot ulcer(DFU).Methods: From December 2016 to December 2017, 92 cases of DFU with deficiency of both Qi and Yin syndrome were randomly divided into treatment group and control group(44 cases in each group). The treatment group was treated with Yinqi ointment, while the control group was treated with mupirocin ointment. After 4 weeks of treatment, the ulcer healing effect, ulcer area, granulation tissue, epithelial tissue coverage,pain score, and dynamic analysis of vascular endothelial growth factor(VEGF), epidermis growth factor(EGF), and basic fibroblast growth factor(bFGF) in local granulation tissue were statistically analyzed before and after treatment in both groups. Results: The total effective rate was 88.37% in the treatment group and 74.42% in the control group. The wound reduction rate, epithelial tissue coverage rate, granulation tissue growth rate, and local pain relief rate in the treatment group were significantly superior to those in the control group(P 0.05). Through the local granulation detection, the treatment group and the control group have increased VEGF, EGF, and bFGF, but the treatment group increased the role of growth factor than the control group. Conclusion: Yinqi ointment can promote the healing of DFU, and its mechanism may be related to the increase of the content of growth factor in granulation tissue.

??Objective    To observe the effects of lithium chloride pretreatment on cognitive ability of aged rats after oral and maxillofacial surgery. Methods    A total of 48 aged male SD rats??18 ~ 20 months old??weight 550 ~ 700 g?? were bought from the Experimental Animal Center of China Medical University . These rats were randomly divided into three groups??including the normal control group??group C??n=16????surgery and anesthesia group??group O??n=16????and lithium chloride preconditioning group??group L??n=16??.Rats in each group were randomly divided into two parts??one part was given Morris water maze test three days after the surgery and its characteristics of behavior tested. Another part was decapitated 24 h after the surgery and extracted and the hippocampus brain separated at the same time. Test expression content of IL-1β GSK-3β p-GSK-3β??ser9??in the hippocampus by Elisa and Western blotting detection method respectively. Results    Morris water maze test showed that??the first day after surgery??latencies of group L and O were significantly longer than group C??compared with group C in swimming distance?? latency and swim distances of group L were shorter than group O. With the comparison of multiple analysis of variance??differences were statistically significant??P??0.05??. Groups L and O in the second day were slightly shortened compared to the first day??on the third day after surgery it has also improved over the second day. Space exploration experiments in rats showed that??the dwell time of group C was significantly longer in the platform quadrant and the frequency of crossing the platform also increased compared with groups L and O. In addition??group L and group O were higher in IL-β levels than group C??the difference being statistically significant by analysis of variance??P??0.05????but group L was significantly lower compared with group O??the difference being statistically significant??P??0.05??. The content of GSK-3β of three groups were of no significant difference??P > 0.05????but p-GSK-3β??ser9??content was significantly lower in group L and O than in group C. The content of GSK-3β of group L was higher than in group O??the difference being statistically significant??P??0.05??. Conclusion    Pretreatment with lithium chloride in postoperative aged rats can inhibit the expression of inflammatory cytokines and increase GSK-3β phosphorylation in the hippocampus cells??so p-GSK-3β??ser9??upregulates and inhibites  the apoptosis of brain cells??thereby improved cognitive abilities after the cavity and maxillofacial surgery.     

Incidence of pressure ulcers in intensive care units and direct costs of treatment: Evidence from Iran

Background and objective

Pressure ulcer (PU) is one of the important and frequent complications of hospitalization, associated with high treatment costs. The present study was conducted to determine the incidence of PU and its direct treatment costs for patients in intensive care unit (ICU) in Iran.

Management of recurrent urinary tract infections in adults

Many women will experience one or more urinary tract infection (UTI) during their life. The most unfortunate will have many. Men presenting with infections, and women with recurrent episodes, require further investigation. A diagnosis of a UTI is often based on a typical spectrum of symptoms, with confirmatory urine cultures lagging a few days behind. Unfortunately, symptoms of a UTI may not be typical, and other conditions can manifest similarly. Treatment of UTI with antibiotics is usually required, but there is increasing awareness of the need for antimicrobial stewardship to avoid the misuse and overuse of antibiotics, even as patients are increasingly reluctant to take them. Recurrent UTI can cause significant morbidity and disruption to daily activities yet investigations rarely demonstrate a reversible cause. There are a host of different antibiotic and non-antibiotic interventions that aim to lower the risk of further infections. However, these are not reliably effective, bring side effects of their own and are often proposed to this desperate population of patients on the back of weak evidence of efficacy.     

Quality of oral anticoagulation control in Chinese patients with non-valvular atrial fibrillation: a prospective controlled study

Abstract

Objective

The sex, age, medical history, treatment, tobacco use, race risk (SAMe-TT₂R₂) Score; the sex, age, medical history, treatment, tobacco use, genotype combination (SAMe-TT₂G₂) Score; and the so-called modified SAMe-TT₂R₂ scores have been proposed to predict the anticoagulation quality for patients with non-valvular atrial fibrillation (NVAF). The data from a prospective controlled study is used to validate the SAMe-TT₂R₂ and SAMe-TT₂G₂ scores in Chinese NVAF patients treated with warfarin and to evaluate the association of factors with time in therapeutic range (TTR) to predict the quality of oral anticoagulation control.     

Current status of peptic ulcer disease in Port Harcourt metropolis,Nigeria

BackgroundEpidemiological studies on peptic ulcer disease (PUD) have shown a recent decrease in hospital admissions in Western countries.ObjectiveThis paper aimed to study the current status and risk factors of PUD in a Nigerian metropolis.MethodsA cross-sectional study of symptomatic patients at upper gastrointestinal (GI) endoscopy diagnosed with PUD from February 2014 to September 2019 at a referral endoscopy facility in Port Harcourt, Niger delta region of Nigeria. The variables studied included demographics, symptoms and duration, blood group, chronic non-steroidal anti-inflammatory (NSAID) use, smoking, endoscopic and histology findings. Statistical analysis was performed using SPSS version 20.ResultsA total of 434 upper GI endoscopies were performed during the study period with thirty-one diagnosis of PUD made. The mean age of gastric ulcer (GU) and duodenal ulcer (DU) cases were 54.4 ± 20.2yrs and 48.1 ± 14.5yrs respectively (p = 0.367). GU to DU ratio was 1.4:1. H. pylori infection, chronic NSAID use and blood group O were seen in 7(22.5%), 8(25.8%) and 18(72.0%) respectively. Major indication in 21(67.7%) cases was gastrointestinal bleeding.ConclusionThere is a low diagnostic rate of PUD (6.7%) with pre-pyloric antral gastric ulcers as most common type and multifactorial aetiology.
