ObjectiveTo investigate the influence of foot bath with traditional Chinese medicine on physical recovery of patients after cesarean section,in order to prevent postoperative complications. Methods180 cases of parturients after cesarean section were divided into the control group and the experimental group with 90 cases in each group according to ward number and bed number.The experimental group began foot bath 6 hours postoperation,and in the next 3 to 5 days,took foot bath at 7:00 to 8:00 and 21:00 to 22:00 every day,20 minutes per time.The control group only received routine nursing.The anus exhaust time and independent ambulation time were observed. ResultsThe anal exhaust time for the first time,independent ambulation time of the experimental group was earlier than the control group. ConclusionsFoot bath with traditional Chinese medicine can promote gastrointestinal function recovery and early ambulation,improve appetite and sleep quality,reduce postoperative complication and promote physical recovery after surgery.

The PET tracer 5-([11C]methyloxy)-L-tryptophan (5-(11)CMTP) was prepared by nucleophilic fluorination and alkylation reaction via a two-step procedure in order to develop specific tumor probe. The biodistribution and microPET imaging of 5-(11)CMTP were executed. The results unveiled that the overall radiochemical yield with no decay correction was (14.6 ±7.2) %, the radiochemical purity was more than 95% and high uptake and long retention time of 5-(11)CMTP in liver, kidney and blood were observed but low uptake in brain and muscle were found, furthermore, high uptake of 5-(11)CMTP in tumor tissue was observed. It seems that 5-(11)CMTP will be a potential amino acid tracer for tumors imaging with PET.

Objective To assess the predictive value of serum uric acid levels to the incident nonalcoholic fatty liver disease(NAFLD)in a cohort of healthy population. Methods A prospective cohort study of NAFLD incidence was conducted in Xinjiang province, from 2012 to 2014. A cohort study was performed on 2 207 subjects with no evidence of fatty liver disease by liver ultrasound and with no major risk factors for liver disease at baseline. All participants were interviewed to carry out the epidemiological questionnaire survey, physical examination, abdominal ultrasonography, as well as blood biochemistry measurements. The hazard ratios of NAFLD were compared among groups with different uric acid levels. All subjects were classified according to serum uric acid (within normal range grouped by quartile: Q1-Q4 group; above the normal range: Q5 group). Results NAFLD was newly diagnosed in 13.72% subjects within the 3-year period. The incidence of NAFLD was increased with elevated serum uric acid quartiles(P<0.01). In multivariate logistic regression, after adjustment for gender, age, race, metabolic syndrome and its components, OR for incident fatty liver in Q2 to Q5 of serum uric acid concentration as compared to Q1 were 2.509, 3.172, 3.392, and 4.041 respectively. Conclusion Elevated serum uric acid concentrations may predict NAFLD in the subjects for a regular health checkup.

Objective To investigate the clinical effects of different doses of propranolol in treatment of infantile mixed and deep hemangioma,and to provid theoretical and experimental evidence for the treatment of hemangioma. Methods The selected 62 patients with mixed and deep hemangioma were divided randomly into low dose (1.5mg·kg-1 ·d-1 )and high dose (3.0 mg·kg-1 ·d-1 )of propranolol groups,3 times a day,6 months as a course,the changes in hemangioma size and the incidence of adverse reactions were recorded.Results The efficacy was evaluated using Achauer system.The total effective rate was 80.65% in low dose of propranolol group and 93.55% in high dose of propranolol group,including 6 cases of class Ⅰ (poor),9 cases of class Ⅱ (moderate), 11 cases of classⅢ (good),and 5 cases of class Ⅳ (excellent)in low dose propranolol group;while 2 cases of class Ⅰ (poor),4 cases of class Ⅱ (moderate),10 cases of class Ⅲ (good)and 15 cases of Ⅳ (excellent)in high dose of propranolol group.The efficacy in high dose of proprandol group was significantly better than that in low dose of proprandol group (P<0.05),there were no significant differences in the efficacies between different sites and different types (P>0.05)and there was no significant difference in the incidence of adverse reaction between two groups (P>0.05).Conclusion The efficacy of oral 3.0 mg·kg-1 ·d-1 propranolol in treatment of infantile mixed and deep hemangioma is increased significantly, and there is no significant adverse reactions after increasing doses.Therefore,high dose of propranolol should be recommended in order to improve the therapeutic effect.

Objective Inflammation is a defensive reaction of body , but excessive inflammatory response can lead to physi-cal injury.The aim of this study was to explore the effects of luteolin on the secretion of inflammatory cytokines from lipopolysaccharide (LPS) and interferon-g(IFN-γ) activated RAW264.7 cells. Methods RAW264.7 cells were divided into 5 groups: control group (without any medicine), M1 group (polarized M1 cells activated by final concentration of 10 ng/mL LPS+20 ng/mL IFN-γ), M1+5L group (simultaneous activation of LPS and IFN-γplus final concentration of 5μmol/L luteolin), M1+10L group(simultaneous activa-tion of LPS and IFN-γplus 10μmol/L luteolin), M1+20L group(simultaneous activation of LPS and IFN-γplus 20μmol/L luteolin). The cell morphological transformation was observed by laser confocal microscope ;the mRNA levels of iNOS , IL-1βand IL-6 were test-ed by real-time quantitative PCR respectively;the secretion levels of TNF-αand IL-6 in culture supernatant were detected by ELISA;the changes of p-STAT3 (ser727) protein pathways were examined by western blot. Results Cellular morphology of activated RAW 264.7 cells changed obviously .Compared with the control group , the mRNA levels of iNOS, IL-1βand IL-6 decreased significantly in the other 4 groups(P<0.05).The iNOS level in M1+20L group significantly de-creased compared with M1 group[(29.52±3.07) vs (98.91±10.65), P<0.01].As to IL-1βlevel, it decreased significantly in M1+10L group(78.38±8.65) and M1+20L group(41.59±6.80) compared with M1 group(110.69±4.12)(P<0.05).While the IL-6 levels decreased significantly in M1+5L group(177.51±19.28), M1+10L group (106.14±5.63), M1+20L group(27.15±1.26), compared with M1 group(394.10±33.47)(P<0.05).LPS+IFN-γcould induce in-creased p-STAT3 (ser727) expression in M1 phenotype of RAW264.7 cells which was proved by its significant increase in M 1 group, M1+5L group and M1+10L group compared with control group (P<0.05).In comparison to M1 group, p-STAT3-ser expression in M1 phenotype downregulated in M1+5L group, M1+10L group, M1+20L group(P<0.05), along with dose-dependent characteristic.Com-pared with control group, the levels of IL-6 and TNF-αincreased significantly in M1 group, M1+5L group and M1+10L group.Com-pared with M1 group, the levels of IL-6 and TNF-αdecreased significantly in M1+5L group, M1+10L group and M1+20L group(P<0.05) , in which IL-6 showed concentration independence and TNF-αshowed no concentration independence . Conclusion Luteolin inhibits the secretion of pro-inflammatory cytokines through the down-regulation of p-STAT3 so as to exert anti-inflammatory effects .

Purpose To investigate the role of PTEN in podocyte injury in patients with diabetic nephropathy ( DN) . Methods Uri-nary samples from 30 patients with DN and 10 healthy volunteers were collected to detect the level of PCX by ELISA. Renal biopsies were reviewed to observe the morphological changes. All patients with DN were divided into three groups by glomerular lesion. The ex-pression of p-Akt and PTEN in glomeruli was detected by immunohistochemistry. Results The levels of PCX in the urine were signifi-cantly higher in patients with DN compared with those in healthy volunteers, and gradually increased along with glomerular lesion aggra-vating. The expression of p-Akt and PTEN increased in patients with DN compared with healthy volunteers. Although the expression of p-Akt and PTEN decreased with the aggravation of glomerular lesion, they were still higher than that in volunteers. There were obvious-ly positive correlation between the level of PCX and 24-h urinary protein and negative correlation between the level of PCX and the ex-pression level of p-Akt and PTEN. Conclusion PTEN down-regulation may be associated with podocyte injury in DN, which may be associated with the phosphorylation of Akt.

Aim To investigate the time-dependent effect of insulin on the expression of SREBP-1(sterol regulatory element binding protein-1),FAS(fat acid synthase)and lipid droplet formation in HKC cells(human renal proximal tubular epithelial cells line).MethodsHKC cells were respectively treated with 100 nmol·L~(-1) insulin for 0,2,4,6,12 h and 24 h.The analysis of SREBP-1 and FAS mRNA was performed by RT-PCR and the expression of SREBP-1 protein was detected by Western blot and immunocytochemistry.Furthermore,Oil Red O staining was used to determine cellular lipid droplet formation.ResultsCompared with HKC cells of 0 h group,there was no difference of SREBP-1 and FAS mRNA in HKC cells of 2 h group.However,the expression of SREBP-1 and FAS mRNA was significantly increased in HKC cells of 4,6 h and 12 h group.Further,the most expression of SREBP-1 and FAS mRNA was at 6 h group and was respectively increased by 3.578 and 4.272 times compared with 0 h group.The results of Western blot showed that the precursor and mature segments of SREBP-1 protein in 4,6 h and 12 h group HKC cells were increased and those of 6 h group HKC cells were the highest and about 4.106 and 5.167 times than those of 0 h group HKC cells.Immunocytochemistry presented the result that SREBP-1 protein was located in the plasma and the expression of 4,6 h and 12 h group HKC cells was significantly higher than that of 0,2 h and 24 h group HKC cells.The result of Oil Red O staining showed that lipid droplet markedly deposited in 6 h group HKC cells,contrarily,no lipid droplet was found in HKC cells of other groups.ConclusionAbove results suggested that insulin up-regulated SREBP-1 and FAS in time-dependent manner that led to cellular lipid droplet deposit,which may play an important role in the pathogenesis of renal lipid accumulation in metabolism syndrome.

Objective:To treat the mixed and deeper infantile hemangioma with ladder dosage propranolol, and to explore its efficacy and safety.Methods:A total of 98 infants with hemangioma were treated by ladder treatment of propranolol.Before treatment,comprehensive assessments of electrocardiogram(ECG),heart color ultrasound, blood glucose,liver function,kidney function,myocardial enzymes and blood routine were conducted.After excluding contraindications,the dose of propranolol incrementally doubled from 0.5 mg·kg-1·d-1 to 4.0 mg·kg-1·d-1.Propranolol was taken 3 times a day.Before and after medication for 1 and 2 h,ECG was monitored.The changes of tumor size,texture,color and other changes or an onset of adverse reactions were dynamicly observed.The infants were visited every month.The efficacy was evaluated using Achauer system.Results: After medication,98 cases had different degrees of color changes or tumor consistency softening.After the dosage of propranolol was increased to 4.0 mg·kg-1·d-1,the change of tumor was the fastest.According to the 4-grade method, there were 84 cases(85.71%) as gradeⅣ (excellent),2 cases (2.04%) as grade Ⅲ (good),4 cases (4.08%) as gradeⅡ (medium)and 8 cases (8.16%) as gradeⅠ (poor).The curative effect of mixed hemangioma was better than that of deeper hemangioma(P<0.05).The recovery time of 74 cases of hemangiomas was 6 months.The major adverse reactions were heart rate decline(5/98,5.10%),drowsiness(3/98,3.06%),diarrhea(7/98,7.14%),loss of appetite (1/98,1.02%), and convulsions (2/98,2.04%).After treatment,all adverse reactions disappeared.Two months after drug withdrawal there were 4 cases of recurrence,and they were continously treated with propranolol.Conclusion: The efficacy of oral ladder dosage propranolol in treatment of mixed and deeper infantile hemangioma is increased significantly and there are no significant adverse reactions.

Aim To investigate the effects of irbesartan on Wnt/β-catenin signaling pathway in tubular epithelial-mesenchymal transition(EMT)in HKCs induced by high-glucose.Methods Human kidney proximal tubular epithelial cell line(HKCs)cultured in vitro was divided into four groups:normal-glucose group,mannitol control group,high-glucose group and high-glucose plus irbesartan group.Immunocytochemistry staining was used to observe the expression of β-catenin;the protein expression of Wnt4,β-catenin,E-cadherin and α-SMA was assessed by Western blot;Wnt4 and β-catenin mRNA were detected by reverse transcription-polymerase chain reaction(RT-PCR).Results Compared with normal-glucose and mannitol control group,both the protein and the mRNA of Wnt4 were up-regulated in HKCs stimulated by high-glucose.α-SMA expression significantly increased but E-cadherin decreased in HG group.The cytoplastic and nuclear fraction of β-catenin enhanced with highglucose stimulation.But no difference of the total protein and mRNA of β-catenin was observed between highglucose-treatment and control groups.Highglucose induced Wnt4 and β-catenin expression in a time-dependent manner,both peaking at 24 h.Irbesartan reduced the promotional effect of HG on Wnt4 and α-SMA expression,and nuclear translocation of β-catenin.HG-mediated inhibition of E-cadherin was also restored by irbesartan.Conclusion These data supported a functional role for Wnt/β-catenin signaling pathway during epithelial-mesenchymal transition of HKCs induced by high glucose and suggested that irbesartan might reverse tubular EMT by regulating activity of Wnt/β-catenin pathway.

Objective To evaluate the efficacy of long-pulsed tunable Nd: YAG laser on capillary hemangioma and to analyse its influencial factors. Methods A retrospective review was conducted on 124 patients with 135 vascular lesions treated with long-pulsed tunable Nd:YAG laser from February, 2007 to January, 2008. Working parameters, including spot size (3-5 mm), pulse duration (10-30 ms) and fluence (120-200 J/cm2) were determined based on the size, color and depth of lesions and adjusted according to the immediate reaction of lesions. The interval of two treatments was 1 month. Results Of the 135 lesions, 100 experienced a more than 95% subsidence, 22 achieved 60%-94% subsidence, 11 got 30% -59% subsidence, and 2 reached less than 30% subsidence. The cure rate and effective rate were 74.07% and 90.37% respectively. Smaller lesions showed a better response to the treatment than larger ones (P<0.0001), whereas the sites and depth of lesions had no effect on the efficacy (both P>0.05). Atrophy scar occurred in 4 (2.96%) lesions, and blisters in 12 (8.89%) lesions after the treatment. No purpura or pigmentary changes occurred. Conclusion The long-pulsed tunable Nd:YAG laser is an effective treatmnt for capillary hemangioma with fast action and few side reactions.
