Objective To investigate the clinical value and effect of peripherally inserted central eatheter(PICC) in patients with tuberculous meningitis. Methods 56 patients with tuberculous meningi-tis were randomly divided into the treatment group and the control group with 28 cases in each group. The treatment group was medicated by PICC, while the patients of the control group were medicated through pe-ripheral superficial vein. The curing rate, degree of anxiety, infusion response, satisfaction with nursing and related expense were recorded. Results The curing rate and satisfaction with nursing of the treatment group were higher than those of the control group. The anxiety degree, infusion response and related ex-pense of the treatment group were lower than those of the control group.Their difference had statistical sig-nificance. Conclusions PICC has clinical value in patients with tuberculous meningitis,which is worth promoting.

Objective To assess the validity of the Oxford classification for pediatric patients with primary IgA nephropathy (IgAN) and to analyze the correlations between clinical characteristics at time of biopsy and the Oxford classification,which identified four definitive histological features:mesangial hypereellularity,endocapillary proliferation,segmental sclerosis and tubular atrophy/interstitial fibrosis.Methods Clinical and pathological characteristics of 35 children with primary IgAN were analyzed.The scoring sheet was based on the Oxford classification of IgAN,and four pathological variables,namely mesangial hypercellularity (M),endocapillary proliferation (E),segmental sclerosis (S),and tubular atrophy/interstitial fibrosis (T) were assessed.A total of 35 children with IgAN were grouped according to the scores(M,E,S,T):the M0 and M1 group,E0 and E1 group,S0 and S1 group,T0 and T1/T2 group.These groups were compared in terms of estimated glomeralar filtration rate (eGFR),mean artery pressure (MAP) and proteinuria at time of biopsy.Results We found that the Oxford classification was significantly negatively correlated with eGFR (Pearson's correlation coefficient r =-0.48).However,the Oxford classification was shown to be positively associated with initial proteinuria per day(Pearson's correlation coefficient r =0.35).The M,E,S,T scores were strongly associated with proteinuria at biopsy (P ＜ 0.05),and the lesion S was not correlated with eGFR (P ＞ 0.05).The lesion T was significantly associated with eGFR (P =0.001) and MAP (P =0.03) at biopsy.Conclusion We confirmed that the Oxford classification of IgA nephropathy was valid for children.In addition,our study indicated that the four histological lesions M,E,S and T were significantly associated with clinical features.

ObjectiveTo investigate the effects of ulinastatin postconditioning and combining ulinastatin postconditioning with pretreatment on myocardial inflammatory response in patients undergoing cardiac valve replacement under CPB.MethodsEighty NYHA class Ⅱ or Ⅲ patients of both sexes aged 21-59 yr undergoing cardiac valve replacement under CPB were randomly divided into 4 groups ( n =20 each): group control (group C) ; group ulinastatin pretreatment ( group U1 ) ; group ulinastatin postconditioning (group U2 ) and group ulinastatin pretreatment and postconditioning combined (group U3 ).Ulinastatin 20 000 U/kg was infused via central vein at 500-1000 U·kg-1 ·min-1 after tracheal intubation until 10 min before cross-clamping of ascending aorta in groups U1 and U3.Ulinastatin 10 000 U/kg was infused into root of aorta at 4000-5000 U· kg- 1 · min- 1 at 5-7 min before declamping of aorta in groups U2 and U3.Blood samples were obtained from radial artery before cross clamping of ascending aorta,at 40 min after aortic cross-clamping,at 45 min after declamping of aorta (T3) and at the end of operation for polymorphonuclear leukocyte (PMN) count,routine analysis of blood and determination of plasma concentrations of IL-10,TNF-α,IL-1 and IL-6 (by ELISA).Myocardial specimens were obtained at 45 min after declamping of aorta for determination of IL-1β and IL-6 expression by immune-histochemistry.Results Ulinastatin pretreatment and/or postconditioning significantly increased plasma IL-10 concentration and decreased plasma IL-1,IL-6,TNF-α concentrations and PMN count and myocardial IL-1β and IL-6 expression in groups U1,U2 and U3 as compared with group C.Plasma IL-10 concentration was significantly higher and plasma IL-1,IL-6 and TNF-α concentrations,PMN count and myocardial IL-1β and IL-6 expression were lower in group U3 than in groups U1 and U2.ConclusionUlinastatin postconditioning can inhibit myocardial imflammatory response in patients undergoing valve replacement under CPB.The protective effect can be augmented by combining ulinastatin postconditioning with pretreatment.

Objective To evaluate the effects of ulinastatin on cardiac function in heart valve replacement patients with cardio-pulmonary bypass (CPB).Methods 120 patients received valve replacements were divided into 4 groups at random.Group U 1,preconditioning group:ulinastatin parenteral solution (20 000 U/kg) was injected into the central veins for 10 min before the ascending aorta was clamped.Group U2,postconditioning group:ulinastatin ( 10 000 U/kg) was injected into the aortic root for 5 min before the aortic clamp was opened.Group U3,combined the treatments of group U1 and group U2.Group C was served as control without using ulinastatin.The ST-T of ECG at different 8 time points was recorded from preanesthesia to the end of operation.The dosage of vasoactive agents in the 4 groups was recorded after the aortic clamp was opened.Blood samples were taken from the radial artery at 4 time points during 1O min before the ascending aorta was clamed to the end of operation for determining the serum concentration of H-FABP,IMA,CK-MB,MDA and SOD.The changes in myocardium were examined by microscope.Results The automatic reheating rate of heart in group U1,group U2,and group U3 were 70％,73％ and 90％ respectively,which were all higher than group C (33％) after the aortic clamp was opened in 3 -5 min.The scores of reperfusion arrhythmia,change of ST segments in ECG ( elevation or depression),the dosage of vasoactive drugs ( dopamine and adrenaline) and their using time,the concentration of MDA,H-FABP,IMA and CK-MB in group U1 and group U2 were ＜ than those of group C ( P ＜0.05 ),but was ＞ than those of group U3 ( P ＜0.05 ).The activity of SOD in group U1 and group U2 were ＞ than those of group C ( P ＜ 0.05 ),but was ＜ than those of group U3 ( P ＜ 0.05 ).There were no significant differences between group U1 and group U2( P ＞0.05 ).The myocardium in group C had focal coagulative necrosis.The damage of myocardium in group U3 was minor,the cytoplasm and nucleus was homogeneous,and the boundaries were distinct.Conclusion Ulinastatin parenteral solution preconditioning and postconditioning could improve heart function after valves replacement on CPB.The protective effects were not significantly different regarding ulinastati was administered into the central veins before the ascending aorta was clamped vs.it was injected into the aortic root before the aortic clamp opening.Combined these 2 administration methods and dosages could produce collaborative protection.

Severe pneumonia is a common disease in intensive care unit (ICU), which is characterized by acute onset, poor prognosis, and can cause multiple systems dysfunction. For critical ill patients, in a state of stress, catabolism is increased, and nutritional risk is extremely high. Proper nutrition treatment can reduce the decomposition of own tissues in the stress period and supplement the protein and energy needed by the body′s metabolism. Therefore, the nutritional treatment of severe pneumonia patients is particularly important. This paper mainly reviews the nutritional literatures of severe pneumonia and critical ill patients in recent years, in order to provide more appropriate nutritional treatment for severe pneumonia patients.

Objective To sum up and analyze the clinical and pathological characteristics in patients with both IgA nephropathy (IgAN) and diabetes mellitus. Methods A total of 500 patients were recruited, including 25 patients with both IgAN and diabetes mellitus, and 475 patients with IgAN only, who were diagnosed by renal-biopsy during Jan 2015 to Jan 2017 at the First Affiliated Hospital of Zhengzhou University. The clinical and pathological data were collected and analyzed using SPSS 22.0. Propensity Score Matching was used to match and select the patients in the both groups, and thereafter the depth of the basement membrane from the matched patients were compared using electron microscopy. The data of the patients whose follow - up time was ≥3 months were retrospectively collected, and Kaplan-Meier analysis was used to compare the difference of the prognosis. Results Compared to the patients with IgAN only, patients with both IgAN and diabetes mellitus were older [(46.36±13.49) years vs (34.00±13.80) years, P<0.001], had higher level of serum triglyceride [2.06(1.52, 3.11) mmol/L vs 1.51(1.01, 2.25) mmol/L, P=0.012] and thicker basement membrane [(384.33 ± 61.20) nm vs (346.72 ± 52.65) nm, P=0.044]. The patients with both IgAN and diabetes mellitus were more prone to reach the composite endpoint [4/7(57.14％) vs 25/265(9.33％), P<0.001] and had worse prognosis (Log-Rank test, P=0.004). Conclusions IgAN patients with diabetes mellitus have different clinical, pathological characteristics and prognosis from patients with IgAN alone. These patients need to be closely monitored and actively treated.

Objective:To investigate the effects of sedatives on the activity of the diaphragm assessed by ultrasound and the timing of extubation in elderly patients after elective surgery.Methods:All 60 eligible elderly patients were randomly divided into three groups: the propofol group, the midazolam group and the control group(n=20, each group). Remifentanil was used in the three groups to keep the Critical Care Pain Observation Tool(CPOT)score less than 3.Patients in the propofol and midazolam groups were given propofol and midazolam sedation respectively, and the Richmond Agitation Sedation Scale(RASS)score was maintained at -2.Diaphragmatic activity was measured, the time from the end of the operation to extubation was recorded, and delirium was evaluated, and the above results were compared with those of the control group, which did not receive sedatives.Results:The activity of the diaphragm was lower in the propofol and midazolam groups than in the control group[(1.10±0.12)cm, (1.17±0.30)cm vs.(1.63±0.25)cm, F=30.170, P=0.000], and there was no significant difference between the propofol group and the midazolam group( t=25.340, P=0.615). There was no significant difference in duration of extubation among the propofol, midazolam and control groups[(1.41±2.08)d, (1.25±1.53)d vs.(1.19±1.40)d, F=0.089, P=0.915]. The incidence of delirium was higher in the midazolam group than in the propofol and control groups[55.0%(11/20), 20.0%(4/20) vs.15.0%(3/20), χ2=5.230, P=0.022, χ2=7.030, P=0.008)], but the difference between the propofol group and control group was not statistically significant( χ2=0.170, P=0.677). Conclusions:The application of sedatives after elective surgery has an effect on the activity of the diaphragm in elderly patients, and the effects of propofol and midazolam are similar.However, propofol and midazolam have no influence on the duration of extubation in elderly patients after elective surgery.Compared with propofol, midazolam increases the incidence of delirium in elderly patients after elective surgery.
