Epidemiological studies have suggested that the increase of uric acid level has a direct correlation with the risk of ischemic stroke. However,the significance of this correlation remains controversy. Most findings have suggested that hyperuricemia is a risk factor for stroke and poor outcome after stroke.Very few studies have suggested that hyperuricemia has protective effect on acute ischemic stroke.Although the effect of hyperuricemia on pathophysiological mechanisms of stroke remains uncertain, the interventional strategy by lowering the levels of blood uric acid for preventing ischemic stroke is worth to be considered. This article mainly reviews the recent clinical trials data and related mechanisms.

Objective To evaluate the effect of implantation of chitosan membrane with triamcinolone(TA) into perichoroidal space combined with intraocular vancomycin injection on the protection of retina in rabbit endophthalmitis.Methods The drug membrane was made of gelatin-chitosan.The right eyes of 30 normal pigment rabbits were inoculated intravitreally with 0.1 ml mixture of 105 CFU standard strain Staphylococcus aureus(ATCC 25923).Twenty-four hours later,rabbits were equally randomized to intravitreal vancomycin group(Group A),intravitreal vancomycin and TA eye dropping(Group B),and intravitreal vancomycin combined with TA membrane implantation(Group C).Clinical observation of ocular fundus was done every day with indirect ophthalmofundoscope.B ultrasound examination was carried out in 24 h after inoculation and on the 14th day after therapy.Electroretinogram(ERG) was done before therapy and the 14th day after therapy.Histopathologic grading and electron microscopy were carried out at the 14th day.Results After implanting the drug membrane into perichoroidal space,the inflammation in group C was markedly less than the other 2 groups,and its inflammation score was significantly lowest(P

AIM: To investigate the effect of urokinase plasminogen activator (uPA) on metastasis inhibition of gastric cancer SGC7901cells induced by parthenolide. METHODS: The changes of SGC7901 cells reproductive activity were analyzed by MTT. Light microscope was used to observe the cell morphological changes. The effects of parthenolide on migration and invasion capacity of SGC7901 cells were determined by using matrigel and transwell system. The expression of uPA was detected by Western blot and RT-PCR assays. RESULTS: Parthenolide inhibited the proliferation of SGC7901 cells in a time-and concentration -dependent manner ranging from 100 to 200 ?mol/L. Light microscopy showed the suppressing effect on growth of SGC7901 cells. After exposed to parthenolide, the migration and invasion capacity of SGC7901 cells were significantly decreased, the number of cells gradually decreased through the basement membrance. The Western blot assay showed that the expression of uPA protein declined gradually after exposed to parthenolide for various period of time. CONCLUSION: Parthenolide can inhibit the growth and metastasis activity of SGC7901 cells, and uPA played an important role in the latter process.

Objective To evaluate the efficacy of isolated ultrafiltration (IUF) for patients with cardiac insufficiency after acut emyocardial infarction (AMI).Methods The acut emyocardial infarction patients admitted from August 2010 to August 2014 were recruited for study.After primary percutaneous coronary intervention (PCI),102 patients presented cardiac insufficiency taking the form of hypotension and acute left heart failure.All heart failure patients dealt with routine medications at first,and were then randomly (random number) divided into two groups,group A was routine medication group and group B was isolated ultrafiltration after routine medication group.Data recorded at different intervals in the same group were analyzed by ANOVA.Data recorded from two groups at the same intervals were analyzed by t test.Data of mortality in the two groups were analyzed by x2 test.P value less than 0.05 was considered statistically significant.Results Of them,51 patients were treated with routine medication resulting in gradual improvement of cardiac function,but the improvement was slower compared with the isolated ultrafiltration group.Other 51 patients were treated with isolated ultrafiltration,and isolated ultrafiltration was discontinued in 2 patients owing to progressive thrombocytopenia and in another one patient owing to systolic blood pressure below 90 mmHg,with clinical manifestations of organ hypoperfusion,poor peripheral circulation,cool clammy skin and oliguria.In the rest of 48 patients in the isolated ultrafiltration group,vital signs were stable,and heart failure symptoms and serum electrolytes improved significantly (P ＜0.05).After one week of using isolated ultrafiltration,left ventricular ejection fraction (LVEF) also improved (P ＜ 0.05).The differences in mortality within one month,the mean ICU stay,the mean hospitalized stay,and the rate of recurrent heart failure were significant between the two groups (P ＜ 0.05)Conclusions The isolated ultrafiltration is a relatively safe and effective strategy for patients with cardiac insufficiency and hypotension after acut emyocardial infarction.

Objective To investigate the attitude of clinical nurses to the practice of holistic nursing and provide basis for establishing harmonious relationships between patients and nurses.Methods primary nurses were randomly selected and underwent investigations on quality check of nursing work quarterly by serf-designed inventory.Results 24 nurses considered it necessary to carry out holistic nursing but 70 of them were reluctant to undertake it.They thought it boring because of the high requirement of holistic nursing and much literal document in practice.Conclusion Nursing services calls out seeking truth and dealing with concrete matters at present.The holistic nursing is not equipped with professional title since serious shortage of nursing staff.The emaphasis should be focused on the health education according to different situations in hospitals.Besides we should practice holistic nursing step by step instead of by the modality.

Objective To discuss the methods and effects of replantation to treat complex thumb severance. Methods 56 cases of complex thumb severance combined with soft tissue defects were treated with simple vessel transplantation, veno flap transplantation, dorsal index digital island flap transplantation, digital artery transfer, transfer of radial index digital artery pedicled island flap, or veno arteriolization. The soft defects were repaired by the transfer of extensor index finger tendon and superficial ring finger flexor tendon. Results 50 cases survived and 6 cases failed, with the survival rate being 89%. 42 cases were followed up for 5 to 25 months. The function of the treated thumbs was assessed as excellent in 10, good in 25 and bad in 7. The excellent and good rate was 83%. Conclusion Complex thumb severance can be treated by unconventional replantation so as to achieve good effects.

Objective To investigate the association of human papilloma virus (HPV) typing and p53 expression with radiosensitivity in patients with cervical cancer.Methods A total of 80 patients with cervical cancer from 2014 to 2016 were enrolled,and among these patients,40 had stage Ⅰ B+ Ⅱ A disease and 40 had stage Ⅱ B +ⅢA disease.HPV genotype was identified and p53 expression was measured.All the patients underwent external and internal pelvic irradiation alone,and the correlation between short-term therapeutic effect and HPV typing/p53 expression was analyzed.The chi-square test or the Fisher's exact test was used for statistical analysis,and Spearman rank correlation analysis was also performed.Results The radiotherapy-insensitive (stable disease+progressive disease) group had higher p53 positive rates than the radiotherapy-sensitive (complete response+partial response) group (stage Ⅰ B+ Ⅱ:100％ vs.80.0％,P=0.044;stage Ⅱ B+ⅢA:100％ vs.90.0％,P=0.013).The expression of p53 was negatively correlated with radiosensitivity (r =-0.427,P =0.000).In the radiotherapy-insensitive group of patients with stage I B + Ⅱ and Ⅱ B +Ⅲ A,the rate of HPV multiple infections was higher than that of single subtype infection (65.0％/95.0％ vs.35.0％/5.0％,P=0.004 and 0.003),while in the radiotherapy-sensitive group,the rate of single subtype infection was higher than that of multiple infections (85.0％/60.0％ vs.15.0％/40.0％,P=0.004 and 0.003).The highest detection rate of HPV16 was 66.3％ in all patients,and the highest detection rate of HPV18 was 60.0％ in the radiotherapy-insensitive group.Conclusions High expression of p53 is associated with radioresistance in patients with cervical cancer.Patients with HPV muhiple infections have poor radiosensitivity,and HPV16 is the most common subtype in dual infection.Among patients who do not achieve remission after radiotherapy,HPV multiple infections with HPV18 as the main pathogen has the highest detection rate.

Objective To study the effect of nonylphenol (NP) on the fertility of mice,and assess its reproductive and developmental toxicity.Methods 128 mature KM mice weighed 22-26 g were randomly divided into three experimental groups (24,60 and 120 mg nonylphenol/kg bw respectively) and the control group (earthnut oil ),16 in each.Fertility tests were performed according to the procedure commended by EPA.Results Sperm number,sperm vitality,fertility index and pregnancy rate decreased,while rate of deformed sperm increased in dose-dependent manner at dose of 60 and 120 mg/kg bw (P

OBJECTIVE To investigate the knowledge about hand hygiene among the outpatients and then take some valid methods to enhance their understanding about hand hygiene.METHODS By randomly asking patients from two departments in a level A of the tertiary hospital,one was a digestion and the other was a non-digestion department question designed by ourselves.The data were generally described by percentage and ?2 test with SPSS 6.0.RESULTS All the patients had not enough and correct hand hygiene knowledge from both two groups.The patients from digestion department paid more attention on their hand hygiene than from non-digestion one.The most patients from both two groups thought they needed to know more about hand hygiene and hospital should equipped with some fast hands cleaning instruments.CONCLUSIONS It is a very important duty for nurses to explain and publicize more about general hygiene and show patients how to clean their hands in order to decrease hospital infection.
