Objective To investigate the effects of hyperuricemia on vascular endothelial function.Methods With high-resolution ultrasound,flow-and nitroglycerin induced dilation,the vasodilation of brachial artery was measured in 30 hyperuricemia male patients and 30 healthy male subjects(control group).Both serum NO and plasma endothelin-1(ET-1) levels were determined at the same time.Results In patients with hyperuricemia,flow-induced vasodilation was much reduced compared with that in the control subjects(P0.05).Plasma NO level in the hyperuricemia group was lower than that in the control group (P

Purpose To detect the expression of CD90 in invasive ductal breast carcinoma with different molecular subtypes and to explore its clinical significance.Methods The expression of CD90,ER,PR,Ki-67 and HER-2 were detected in 80 cases of invasive ductal breast carcinoma tissue and 20 cases of breast benign lesion with immunohistochemical method.The relationship between CD90 and clinicopathological parameters were analyzed.Results The positive expression rate of CD90 in invasive ductal breast carcinoma and breast benign lesion tissues were 62.5％ and 20.0％,respectively (P ＜0.001).The expression of CD90 in invasive ductal breast carcinoma was correlated with lymph node metastasis (P ＜ 0.05),but not with age,tumor size,TNM staging and histological grade (P ＞ 0.05).Among different molecular subtypes,CD90 expression level in Luminal A type was the lowest (40.0％),and the level in triple negative type was the highest (82.4％) (P ＜0.05).CD90 expression level was negatively correlated with ER (r=-0.342,P＜0.05) orPR (r=-0.374,P＜0.05) expression level,but not with Ki-67 (r =0.084,P ＞ 0.05).Condusion The over-expression of CD90 is related with molecular subtypes of breast carcinoma,and its high expression suggests a poor prognosis.

Objective To investigate the impact of initial dialysis dose on residual renal function of peritoneal dialysis patients. Methods Clinical data of 178 consecutive patients on initial peritoneal dialysis received follow-up for 3 months in our department were analyzed retrospectively. According to urinary volume after peritoneal dialysis, patients were divided into three groups: lower urine group (LU, n=97), decreased urine group (DU, n=19), and normal urine group (NU, n=62). Their dialysate volume, dialysate glucose content, uhrafiltration, weekly renal urea clearance normalized to total body water (Kt/V), body weight, edema degree and daily urinary volume were recorded and association among these parameters were examined. Results There were no significant differences in age, gender, serum albumin and total Kt/V among three groups. One month after dialysis, body weight and edema degree in DU group were significantly higher than those in LU and NU groups (all P<0.05); the dialysate volume, dialysate glucose content, ultrafiltration and renal Kt/V in DU group were significantly higher than those in LU group (all P<0.05), but were not significantly different from NU group. Three months after dialysis, in DU group, dialysate volume, ultrafiltration and urinary volume decreased significantly (P<0.05) as compared with LU and NU groups, but body weight and edema degree were still higher, and Kt/V decreased significantly as well. Conclusions The residual renal function (urinary volume and Kt/V value) of initial patients will be deteriorated by over ultrafihration in early stage of peritoneal dialysis. Excess uhrafiltration should be avoided for the initial peritoneal dialysis patients.

Objective An 80 years old man,suffered from cardiopulmonary arrest during swimming.After successfully cardiopulmonary resuscitation,he was sent to a hospital.After examination and inspection,he was diagnosed as cardiopulmonary arrest,aspiration pneumonia,hyperlipidemia,high level of creatine kinase.We prescribed a statin for the hyperlipidemia,but the level of creatine kinase was higher and higher.Finally he was diagnosed as hypothyroidism and lung cancer.We considered that severe weakness may be the reason of cardiopulmonary arrest in swimming pool.

Objective:To report one case of diabetic ketoacidosis complicated by acute myocardial infarction and upper gastrointestinal bleeding, and make a certain summary to its diagnosis and treatment in order to improve the treatment of these critically ill patients.Methods:One patient was admitted to Guizhou Aerospace Hospital on November 14, 2021 due to fatigue and vomiting for 2 days, and worsened symptoms accompanied by poor consciousness for 1 day. The patient was diagnosed with diabetic ketoacidosis complicated by acute myocardial infarction and upper gastrointestinal bleeding. The clinical symptoms, signs, laboratory examinations, and follow-ups of the patient were analyzed systematically and retrospectively.Results:After volume state assessment using a combined way, the patient was treated with appropriate fluid replacement, hypoglycemic, antiplatelet, anticoagulant, and acid inhibition strategies. After treatment, ketoacidosis and upper gastrointestinal bleeding were corrected, blood glucose gradually stabilized, and myocardial necrosis markers troponin and N-terminal brain natriuretic peptide precursor became normal.Conclusion:Treatments of diabetic ketoacidosis, acute myocardial infarction, and upper gastrointestinal bleeding are contradictory. Therefore, analyzing this patient's diagnosis and treatment is of great significance for improving treatment and reducing the mortality of these critically ill patients.

Application of network pharmacology in traditional Chinese medicine (TCM) will be benefit for clarifying active components and mechanism of action of TCM and increase the study level of new drug of Chinese medicine. ADME process can identify drug components from TCM and obtain the possible metabolites which can clarify active components in vivo. For the complexity of active constituents of TCM, it indicated that the ADME process will be the precondition for application of network pharmacology in TCM. This paper introduced the study ideas of the combination of ADME process in vivo and network pharmacology.

Objective To observe the effect of epidural analgesia after cesarean section on the function of lactation. Methods 100 primi-parous women were selected from our hospital,randomly divided into observation group(PCEA) and control group(muscle injection pethidine hydrochloride). The changes of vital signs ,analgesia and lactation were observed. Results The VAS of observation group was significantly lower than that of control group(P < 0.01). The quantity of lactation in observation group was significantly more than that of control group(P < 0.05). Conclusion Postoperative analgesia with epidural analgesia after cesarean section can increase the quantity of lactation and promote the time of colostrum.

Objective To investigate the effects of psychological intervention on relieving the emotional state and improving life quality for patients with leukemia during clinical nursing.Methods A total of 120 cases of leukemia were collected to follow up one year,and were divided into routine treatment group (60 cases) and psychological intervention group (60 cases) respectively.The emotional states of both groups were compared using hospital anxiety and depression scale (HADS),while the life quality of patients was assessed andcompared by quality of life questionnaire (EORTC-QLQ).Results Mter one year of follow-up,the mean HADS score of routine treatment group was (8.3 ± 3.2),whereas that of psychological intervention group was (6.2 ± 4.1) with significant difference between two groups (P ＜ 0.05).The assessments of overall health status,role function,emotional function and social function from EORTC-QLQ for both groups patients were significantly different after one-year follow-up (P ＜ 0.05).The HADS scores of patient with different types of leukemia varied statistically as well (P ＜ 0.01).Conclusions Psychological intervention for patients with leukemia during treatment can relieve the symptoms of depression significantly and improve the quality of life,which is prognosis favorable.

Novel reassortant H3N2 swine influenza viruses (SwIV) with the matrix gene from the 2009 H1N1 pandemic virus have been isolated in many countries as well as during outbreaks in multiple states in the United States, indicating that H3N2 SwIV might be a potential threat to public health. Since southern China is the world's largest producer of pigs, efficient vaccines should be developed to prevent pigs from acquiring H3N2 subtype SwIV infections, and thus limit the possibility of SwIV infection at agricultural fairs. In this study, a high-growth reassortant virus (GD/PR8) was generated by plasmid-based reverse genetics and tested as a candidate inactivated vaccine. The protective efficacy of this vaccine was evaluated in mice by challenging them with another H3N2 SwIV isolate [A/Swine/Heilongjiang/1/05 (H3N2) (HLJ/05)]. Prime and booster inoculation with GD/PR8 vaccine yielded high-titer serum hemagglutination inhibiting antibodies and IgG antibodies. Complete protection of mice against H3N2 SwIV was observed, with significantly reduced lung lesion and viral loads in vaccine-inoculated mice relative to mock-vaccinated controls. These results suggest that the GD/PR8 vaccine may serve as a promising candidate for rapid intervention of H3N2 SwIV outbreaks in China.
