Objective To determine the optimal volume proportion of iodize d oil (Lipiodol)-ethanol mixture by comparing the clinical efficacy of transhepatic arterial embolization-ablation therapy using different volume proportion of Lipiodol-ethanol mixture in treating experimental rabbit models with VX 2 liver cancer. Methods VX2 tumor was implanted in eighteen adult male New Zealand white rabbits. The 18 VX 2 rabbit models were randomly and equally divided into the following six groups according to the Lipiodol-ethanol volume ratio ∶ group A (3 ∶ 1), group B (2 ∶ 1), group C (1 ∶ 1), group D (1 ∶ 2), group E (1 ∶ 3) and group F (1 ∶ 4). One week after the treatment, all the rabbits were sacrificed and their livers were removed and sent for pathologic examination. The tumor growth rate, the microvascular density, the apoptosis index (AI) of tumor tissues and the injury of the hepatic tissue adjacent to the tumor were evaluated. Results After the treatment, the tumor’s size was increased in group A, E and F. The tumor growth rate of group A was significantly higher than that of the other five groups , and the difference was statistically significant (P<0.05). The tumor’s size of groups B, C and D was decreased, although the difference was not significant when compared with the tumor’s size of groups E and F (P > 0.05). The proportion of ethanol in Lipiodol ∶ethanol mixture bore a negative relationship to the microvascular density counts (R2= 0.840, F = 89.432, P < 0.001). AI of group A was strikingly lower than that of groups C, D, E and F (P < 0.05). The difference in AI between group A and group B was not significant (P > 0.05), while the difference in AI between group B and group C or between group B and group F was statistically significant (P<0.05), and no significant difference in AI existed between each other among other groups (P > 0.05). The injury extent of the hepatic tissue adjacent to the tumor in group A and B was remarkably milder than that of other groups (P < 0.05). Conclusion When considered in terms of safety, the optimal volume proportion of Lipiodol-ethanol mixture should be 2 ∶ 1. Successful super-selective catheterization of the tumor feeding artery, strict and close fluoroscopic monitoring of the injection and proper increase in the proportion of ethanol can definitely improve the therapeutic efficacy.

Methods Divided 112 children with primary nocturnal ensuresis into the research group (40 cases) and the control group (72 cases). Routine treatment and nursing cares were used in the control group, while the psychological nursing was used in the research group in addition. Compared the treatment effect betweent the two groups. Results The efficient rate in the research group was 90.0%, which higher than that of in the control group significantly. Conclusions Psychological nursing intervention can effective promote the rehabilitation for children with primary nocturnal ensuresis.

Objective To assess efficacy, infection rate and recurrence rate of tacrolimus prescribed in infants with steroid-resistant nephrotic syndrome (SRNS). Method From August 2011 to August 2014, 22 cases of SRNS infants (treatment group) received oral tacrolinms treatment, 0.1 to 0.15 mg/ kg per day and once every 12 hours were enrolled in this retrospective longitudinal study and were compared with 23 cases infant SRNS (control group) treated with high-dose methylprednisolone pulse therapy. Followed up for 1 year we analysed the data of proteinuria, lymphocyte count, proteinuria relapse and complication (infection, hyperglycemia) of the two groups’ patients at every point time. Results The pathology of the patients maintains of MCD, MsPGN, FSGS and IgM nephropathy so on. Follow-up to 6 months, the total remission rate 95.45% of treatment group was significantly higher than that in control group (60.87%). Follow-up to 6 months , 24 h urinary protein of the treatment group were respectively 67.88 mg/(kg·d) which were remarkably lower than base line [657.5 mg/(kg·d)], meanwhile which were obviously lower than the 6th month point of control group [305.55 mg/(kg·d)]. Lymphocyte counts had been done during the initial and the destination in the treatment group. Follow-up to 12 months, the CD4+ 795.16/uL, CD8+ 496.85/uL, CD19+ 358.23/uL had decreased observably than when at origin what was 2697.45/uL, 2265.63/uL, 1579.34/uL. Followed-up 1 year, the person-time of infection of treatment group existed superior to the control groups; The recurrence rate was 71.43% in treatment group, which compared with control groups (60.87%) without no significant difference. The treatment group with BG and CCr maintained stably. Conclusion Tacrolimus show its own advantages of reliable effect and less side-effect on the infant with steroid-resistant nephrotic symdrome associated with genes , but it could not lessen the relapse of the disease, and it′s long-term prognosis is still not very clear.

Objective To analyze the peculiarity of infants steroid-resistant nephrotic syndrome (SRNS) and to assess the efficacy,side-effect and relapse of various of Tacrolimus prescribed in infants SRNS.Methods A total of 76 case of infant SRNS from August 2012 to August 2015 in Guangzhou Weman and Children's Medical Center grouped into oral Tacrolimus (TAC group),Methyprenisolone pulse therapy (MP group) and Methyprenisolong combined Cyclophosphamide(CTX) pulse therapy(MP + CTX group),were observed for 1 year,and the urine protein excretion,renal function (CCr),blood glucose (B G),urine retinal-binding-protein (URBP),lymphocyte count etc.were recorded and the situation of infection and relapse regularly were monitored regularly.The data were retrospectively analyzed by the statistical method.Results All SRNS children underwent kidney biopsy,and 36 cases of minimal change disease,32 cases of mesangial proliferative glomerulonephritis and 8 cases of focal segmental glome-rulosclerosis were contained in the patients.The pathological constituent ratios were not obviously different among these 3 groups.By 6-month follow-up,the complete remission ratio of TAC group was 63.64％,the total remission ratio was 95.45％,which were remarkably higher than those of MP group (26.09％,60.87％) and MP + CTX group (41.94％,74.19％);the urine protein excretion of TAC group [(7.8 ± 8.6) mg/(kg · d)] was distinctly lower than that of pretreatment and lower than that of MP group [(144.2 ± 118.3) mg/(kg · d)],and lower than that of MP + CTX group [(91.3 ± 87.4) mg/(kg · d)],and the difference was significant (F =22.69,P ＜ 0.05).The remission time of TAC group was about 2 months,that of other two groups was about 3 months.By 1-year follow-up,the lymphocyte counts including total T-cell (CD3 +),the helper T-cell (CD4 +) and the inhibited T-cell (CD8 +) of TAC group decreased obviously(all P ＜ 0.01),which were extremely lower than those of the M P group and MP + CTX group,and there were significant differences (all P ＜ 0.05).By 1-year follow-up,the person-time of infection existed superior to the other 2 groups,TAC group was compared with MP plus group,the rank sum was 348.5 (U =-3.69,P ＜ 0.01);compared with MP + CTX plus group,the rank sum was 369.5 (U =-4.18,P ＜ 0.01).During the observation the URBP of TAC group was distinctly higher than that of the MP group and the MP + CTX group [(13.77 ± 19.19) mg/L vs.(2.50 ± 1.77) mg/L,(2.06 ±3.63) mg/L],and the differences were significant(t =3.16,2.99,all P ＜0.05);the TAC group with BG and CCr maintained stably.Conclusions Tacrolimus shows its own advantages of more reliable effect and less side-effect in the infants with SRNS over MP therapy and MP combined CTX therapy,but it could not lessen the recurrence of the disease,and its long-term prognosis is still not very clear.

Objective To explore the effect of urine neutrophil gelatinase-associated lipocalin(uNGAL) and urine interleukin-18(uIL-18) on the ill condition and prognosis in critically ill patients with acute kidney injury (AKI) at inception of continuous veno-venous hemofiltration (CVVH).Methods Children came from Department of Nephrology,PICU and health examination center in Guangzhou Women and Children's Medical Center were divided into 4 groups:critically ill patients with AKI receiving CVVH group(group A),critically ill patients with non-AKI receiving CVVH group(group B),critically ill patients with AKI didn't recevie CVVH group(group C),and healthy control group(group D).Serum creatinine(SCr),uNGAL and uIL-18 in all patients were analyzed.Results The uNGAL in group A and group C [(161.56 ± 71.44) μg/L,(153.69 ±51.33) μg/L] increased obviously when compared with group B and group D [(33.50 ± l 0.76) μg/L,(16.37 ± 6.20) μg/L] (all P ＜ 0.05).The uIL-18 in group A and group C[(4.16 ±1.13) μg/L,(3.81 ± 1.05) μg/L] was higher than that in group B and group D [(0.25 ± 0.04) μg/L,(0.19 ± 0.15) μg/L] (all P ＜ 0.05).There was no significance of uNGAL and uIL-18 between group B and group D(all P ＞ 0.05).The peak level of uNGAL[(241.76 ± 53.60) μg/L vs (196.32 ± 39.28) μg/L] and uIL-18[(5.15 ±0.78) μg/L vs (4.30 ±0.89) μg/L] in critically ill patients with AKI was higher in renal recoveries than in renal non-recoveries(P ＜0.05).The levels of uNGAL and uIL-18 critically ill patients at initiation of CVVH were higher in non-survivors when compared with survivors [(213.50 ± 104.78) μg/L vs (79.91 ± 55.81) μg/L,P ＜ 0.05],[(4.48 ± 2.32) μg/L vs (1.94 ± 1.88) μg/L,P ＜ 0.05].The levels of uNGAL and uIL-18 of critically ill patients with AKI at initiation of CVVH were higher in non-survivors than in survivors [(256.99 ± 49.33) μg/Lvs (127.11 ±38.99) μg/L,P＜0.05],[(5.48±0.67) μg/Lvs (3.65 ±0.98) μg/L,P＜0.05].The levels of uNGAL and uIL-18 at the first diagnosis time of AKI were higher in non-survivors than in survivors (P ＜ 0.05).Conclusions uNGAL and urine IL-18 at commencement of CVVH predicts short-term prognosis in critically ill patients with AKI.uNGAL and urine IL-18 can be as a prognostic value in the prediction of the need for renal replacement therapy initiation or mortality in critically ill patients with AKI.

OBJECTIVETo probe the risk of colorectal polyp, colon and rectal carcinoma and the intake of NSAIDs.

METHODSCase-control study participants were from patients who underwent colonoscopy at different hospitals, the persons with the above disease was as cases, and those without the above diseases was as controls. Use of NSAIDs was assessed by interviewing the participants with a questionnaire which include a list of NSAIDs and related dietary and life style factors and family history.

RESULTSThere are 37 cases of colorectal polyp, 105 cases of colon carcinoma and 142 cases of rectal carcinoma and 66 controls. Adjusted for potential confounders, the risk of colorectal polyposis, colon carcinoma and rectal carcinoma were markedly reduced by NSAIDs. The OR values were 0.21 (95% CI 0.07-0.65, P = 0.007), 0.13 (95% CI 0.05-0.35, P < 0.001), 0.15 (95% CI 0.11-0.58, P < 0.001) respectively. The risk of the above diseases were also reduced markedly by aspirin, the OR values were 0.265 (95% CI 0.07-0.96, P = 0.044), 0.10 (95% CI 0.03-0.35, P < 0.001), 0.15 (95% CI 0.04-0.49, P = 0.002) respectively. The risk of colon carcinoma was also reduced by profen, with the OR being 0.11 (95% CI 0.02-0.64, P = 0.014).

CONCLUSIONSAspirin and other NSAIDs could reduced the risk of colorectal polyp, colon carcinoma and rectal carcinoma markedly. Aspirin was the most prospective chemopreventive agents for colorectal polyp, colon and rectal carcinoma for its capability of reducing the risk of cardio-cerebral vascular disease as well.

Objective To study the cognitive impairment in SD rats after intermittent hypoxia (IH),and explore the relation of miR-26b up-regulated expression and neuron apoptosis in the hippocampus of SD rats after IH.Methods Eight-week-old male SD rats (n=20,each weighing approximately 300±10 g) were randomly divided into normal oxygen control group,IH 1-week group,IH 2-weeks group and IH 4-weeks group (n=5).Rats in the later three groups were given IH for different times,and rats in the normal oxygen control group were given normal oxygen.The spatial learning and memory abilities were detected by Morris Water Maze (MWM) in the normal oxygen control group and IH 4-weeks group.The levels of apoptosis proteins Caspase3 and Bax and anti-apoptosis protein Bcl-2 in the hippocampus of 4 groups were detected by Western blotting.The miR-26b expression level in the 4 groups was detected by real time-PCR.Results (1) The results of MWM revealed that the mean escape latency in the IH 4-weeks group was significantly prolonged as compared with that in the normal oxygen control group (P＜0.05);the time entering into the target quadrant in the IH 4-weeks group ([22.0±6.7] s) was significantly shorter than that in the normal oxygen control group ([39.8±8.8] s,P＜0.05).(2) Western blotting indicated that up-regulated expressions of apoptosis proteins Bax and Casepase3 and down-regulated expression of anti-apoptosis protein Bcl-2 in the IH 1-week group,IH 2-weeks group and IH 4-weeks group were noted as compared with those in the control group,with significant differences (P＜0.05);significantly higher apoptosis protein Bax and Casepase3 expressions in the IH 1-week group were noted as compared with those in the IH 2-weeks group and IH 4-weeks group (P＜0.05),while significantly decreased Bcl-2 expression in the IH 1-week group was noted as compared with that in the IH 2-weeks group and IH 4-weeks group (P＜0.05).(3) The results of real time-PCR revealed that the miR-26b expression level in the hippocampus was up-regulated in the IH 1-week group,IH 2-weeks group and IH 4-weeks group as compared with that in the control group,with significant differences (P＜0.05);miR-26b expression level in the IH 1-week group was significantly higher as compared with that in the IH 2-weeks group and IH 4-weeks group (P＜0.05).Conclusion The miR-26b up-regulated expression in the hippocampus might refer to Bax /Bcl-2-related mitochondrial apoptotic signaling pathway after IH brain injury;miR-26b could be a potential mean ofgene therapy after IH brain injury.

Objective To investigate the changes of microglia cell phenotypes in the injured brains of rats following repetitive mild traumatic brain injury (rmTBI).Methods Sixty male SD rats were randomly divided into sham-operated group,injury of one-week group,injury of two-week group,injury of four-week group,and injury of six-week group (n=12).Rats in the injury groups were induced rmTBI models by controlled cortical impact (CCI),and rats in the sham-operated group were only performed bone window opening without hitting.Six rats from each group were sacrificed;immunofluorescent staining was used to detect the Iba-1 positive microglial cells in the injured cortex and changes ofmicroglia subsets in the injured brain after rmTBI were analyzed by flow cytometry.Results As compared with the sham-operated group,the injury of one-week group and injury of six-week group had significantly increased percentages of Iba-1 positive microglial cells in the injured cortex (19％ and 12％,P＜0.05).flow cytometry indicated that CD451ow/CD11b+ cells were the microglial cells,accountting for 90％ ofCD11b+ cells;as compared with the sham-operated group,the injury of one-week group,injury of two-week group,injury of four-week group,and injury of six-week group had significantly increased M1 type microglial cells (P＜0.06),with injury of six-week group enjoying the highest level;as compared with the sham-operated group,the injury of one-week group,injury of two-week group and injury of four-week group had significantly increased M2 type microglial cells (P＜0.06),with injury of two-week group enjoying the highest level.Conclusion Dynamic changes ofmicroglia subsets after rmTBI are noted,which reveals that different subsets of microglia phenotypes might play their unique roles in the acute or chronic phases after rmTBI.

Schizophrenia is a serious mental disease. The diagnosis of schizophrenia so far relies heavily on subjective evidence, including self-reported experiences by patients, manifestations described by relatives, and abnormal behaviors assessed by psychiatrists. The diagnosis, monitoring of the disease progression and therapy efficacy assessment are challenging due to the lack of established laboratory biomarkers. Based on the current literature, clinical consensus, guidelines, and expert recommendations, this review highlighted evidence-based potential laboratory biomarkers for the diagnosis of schizophrenia, including genetic biomarkers, neurotransmitters, neurodevelopmental-related proteins, and intestinal flora, and discussed the potential future directions for the application of these biomarkers in this field, aiming to provide an objective basis for the use of these biomarkers in the early and accurate diagnosis, treatment, and prognosis and rehabilitation assessment of schizophrenia.
