Objective To explore the clinical effects of enema combined with massage therapy on jaundice in premature infants.Methods Seventy-five premature infants with jaundice were randomly divided into 3 groups,enema combined message therapy group(group A),abdominal massage therapy group(group B),and double-side phototherapy group(group C).All 3 groups were received the same formula fee-ding,intravenous nutrition and identical drug treatment.Group A was given enema with mixed kaiselu and normal saline together with 60 times clockwise abdominal massage once a day for 2 weeks.Group B only received abdominal massage twice per day for 2 weeks.Transcutaneous bilirubin(TB) indexes of all the premature infants in the 3 groups were detected and transformed into total TB concentrations every morning,through version of MINOLTA JM-102 transcutaneous bilirubin radiometer made in Japan.When TB index counted more than 196.58 ?mol/L,group A and B were given single-side phototherapy for 24 hours.Neither enema nor abdominal massage was given to group C,and double-side phototherapy was applied when TB indexes were above 196.58 ?mol/L.Daily TB indexes,duration of jaundice and phototherapy,time of meconium exhaustion,defecation times in each day,incidence of constipation and feeding intolerance were recorded.Results Duration of jaunhospitalized and phototherapy were significantly shortened in group A compared with those of the other groups.In 34 premature infants who were hospital for at least 2 weeks,TB indexes in group C were lower than those in group B on the 9th day.On the 12th day and the 14th day,TB indexes in group A and C were lower than those in group B(Pa

Objective To assess the diagnostic value of CT spectral imaging using quantitative iodine-based material decomposition images in the evaluation of pulmonary embolism. Methods Fifty-three patients underwent CT angiography with spectral imaging mode on a GE Discovery CT750HD scanner. Iodine distribution in the lung parenchyma using the iodine-based material decomposition images was quantitatively measured by post-processing. Monochromatic CT angiographic images were reconstructed from the same data sets and thee images were reviewed for the identification and localization of pulmonary embolism as well as the degree ( partial or complete) of the embolic occlusion. The number and location of perfusion defects were recorded. The iodine content of perfusion defects and normal lung parenchyma on the iodine maps were measured by one reader using an ROI analysis. Comparative analyses were obtained using the Chi-square test for categorical data. Two independent samples rank test and 2 related samples signed-rank test were used to compare iodine densities between different groups. Results CT angiography showed no pulmonary embolism in 33 patients, and iodine distribution was homogeneous. A total of 93 clots with lobar ( n = 26), segmental (n = 54) and sub-segmental (n=13) distribution were detected in 19 patients; Fifty-one clots were occlusive and 42 clots were non-occlusive. The iodine-based material decomposition images of all occlusive clots showed lobar, segmental or sub-segmental iodine distribution defects; whereas eleven of 42 non-occlusive clots had evidence of iodine distribution defects. There was significant difference ( x2 = 39. 94,P＜0. 01 ) in the perfusion defects between occlusive and non-occlusive clots. There was a significant difference in iodine content between normal lung parenchyma [ (1.92 ±0. 54) g/L] and perfusion defects [ (0. 30 ± 0. 20)g/L] (Z= -5.63, P ＜ 0. 01 ). There was a significant difference in the iodine content of peffusion defects before [ (0. 26 ± 0. 23 )g/L] and after anticoagulation [ (0. 94 ± 0. 50 )g/L ] ( Z = -3.93,P ＜ 0. 01 ). Conclusion With the ability of iodine mapping, CT spectral imaging is areliable method in the evaluation of pulmonary embolism both qualitatively and quantitatively, and may be a useful tool in providing information regarding the severity of PE and monitoring therapeutic efficacy.

Objective To investigate the influence of probiotics on gastrointestinal motility and hormone secretion of rats with severe brain injury. Methods Severe brain injury rats were prepared. 54 Sprague-Dawley rats were randomized into three groups: group A ( sham-operation), group B ( standard enteral nutrition) and group C (standard enteral nutrition plus probiotics). Each group was equally divided into three subgroups on 1 d, 3d, 7 d, respectively. Gastric emptying rate, intestinal transmission rate, motilin ( MTL) and calcitonin gene related protein (CGRP) level in plasma were measured 1 d, 3 d, 7 d post trauma. Results Compared with group A, gastric emptying rate and intestinal transmission rate decreased significantly on 1 d post trauma(P <0. 01). They were still much lower in group B on 3 d post trauma(P < 0. 01), while they increased significantly in group C on 3 d post trauma(P <0.05). MTL and CGRP level in plasma increased significantly after severe brain injury; however, the levels in group B were much higher than those in group C on 1 d and 3d(P<0.01). There was no significant difference among the three groups regarding gastric emptying rate, intestinal transmission rate, and MTL and CGRP level. Conclusions Severe brain injury could induce disorder of gastrointestinal motility and dysfunction of hormone level. Early enteral nutrition supplemented with probiotics could improve gastrointestinal motility and transmission and regulate highly increased gastrointestinal hormone after severe brain injury.

ObjectiveTo determine the impact of lupus flares on maternal and fetal outcomes in pregnant patients with systemic lupus erythematosus(SLE).MethodsData was obtained from 46 pregnancies of 44 pregnant women with SLE.The relationship between lupus flares and pregnant outcomes,and the risk factors for adverse maternal and fetal prognosis were analyzed.T-test,X2 test or Fisher's exact test and Logistic regression were used for statistical analysis.Results① Lupus flares occurred in19(41％)pregnancies(group A) and stable lupus disease was observed in 27(59％) pregnancies(group B) during pregnancy.Compared to pregnancies in patients with stable lupus disease at the conception(n=32),pregnancies in patients with unstable lupus disease at the conception(n=8) had higher lupus flare during pregnancy( 100％ vs 16％,P＜0.05).(②) The common manifestations of lupus flares during pregnancy were lupus nephritis (LN) (11 cases),skin rashes (10 cases),arthritis (7 cases),and the common complication was infection ( 11 cases).(③) The incidence of premature labor,fetal growth retardation (FGR) and fetal loss in group A was 42％,47％ and 26％ respectively,which was significantly higher than that of the group B (7％,15％ and 0 respectively)(P＜0.05).There was no difference in the incidence of preeclampsia,fetal distress and neonatal asphyxia between the two groups ( 16％ vs 7％,16％ vs 19％,5％ vs O,respectively,P＞0.05).The incidence of premature labor and FGR in patients with active LN was higher than that of patients without active LN (55％ vs 11％,64％ vs 17％,respectively,P＜0.05).(④)The binary Logistic regression analysis showed that renal impairment,hypocomplementemia,aPL and serum urea nitrogen level were independent risk factors for premature delivery,FGR,fetal loss and fetal distress.Conclusion(①) Lupus flares during pregnancy increase the incidence of premature labor,FGR and fetal loss.Active LN during pregnancy can increase the incidence of premature labor and FGR.② Renal impairment,hypocomplementemia,aPL and serum urea nitrogen level are associated with adverse fetal outcomes in pregnant patients with SLE.

Objective To improve the safety of surgery,the application of indocyanine green fluorescein(ICG)angiography in intracranial aneurysm surgery was investigated.Methods Fifty cases of intracranial aneurysms were retrospectively analyzed.All the patients were received ICG angiography before and after intracranial aneurysm clipping.The efficiency of the surgery was evalu-ated with CT angiography(CTA)and(or)digital subtraction angiography(DSA).The postoperative follow-up was conducted using Glasow outcomes score(GOS).Results Of the 50 patients,3 cases of aneurysmal neck remnant,one case of parent arteries steno-sis,one case of nearby branch stenosis and two cases of “false-negative”were observed after ICG angiography.The clips were adjus-ted until the satisfactory blood flew was restored.Postoperative CTA and(or)DSA confirmed the results of intraoperative ICG an-giography.Of the 40 patients underwent follow-up,GOS score was 5 in 30 cases,4 in 7 case,3 in 2 case and 2 in 1 case.Conclusion ICG angiography is a useful way to assess the clipping of aneurysms,blood flew of parent arteries and nearby branches during the aneurysm surgery.It could raise the safety of surgery and further improve the clinical outcomes of intracranial aneurysms.

BACKGROUND: Fish oil is one of mainly natural resources of n-3 fatty acids, which can inhibit cardiac allograft vasculopathy (CAV) and prolong the survival of cardiac allograft. But, the mechanism is unclear. Recent in vitro data suggested that n-3 fatty acids could inhibit the release of inflammatory transmitter by the activation of peroxisome proliferator-activated receptor-y (PPARy). OBJECTIVE: To test the hypothesis that n-3 fatty acids from fish oil ameliorates CAV development via activating PPARy. METHODS: A total of 6 Lewis rats and 18 Fisher344 rats were randomly selected as heart donors. An additional 24 Lewis rats were randomly and equally divided into 4 groups. In isograft group, heart transplantation was performed among Lewis rats, without any drug. In low-dose fish oil-treated group, F344→Lewis transplantation was performed. At 1 day following surgery, 0.03 mL/kg fish oil was treated by gavage for 8 weeks. In high-dose fish oil-treated group, F344→Lewis transplantation was conducted. At 1 day following surgery, 0.06 mL/kg fish oil was treated by gavage for 8 weeks. In control group, F344→Lawis transplantation was conducted. Cyclosporine A was administrated by gavage for 8 weeks. In the low-dose and high-dose fish oil-treated groups, cyclosporine A (1.5 mg/kg) was given daily by intramuscular injection for 2 weeks following surgery. CAV was evaluated by histological examination. Activity of nuclear factor (NF) k-B and PPARy was assessed in homogenate. Contents of monocyte chemoattractant protein-1 and interferon-inducible protein 10 were measured by enzyme-labeled immunosorbent assay (ELISA). Chemokine receptor CCR2 and CXCR3 expression was determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). RESULTS AND CONCLUSION: All 24 receptor Lewis rats were survived following surgery. The donor heart could regularly beat at 8 weeks following transplantation. Compared with the isograft group, severe CAV was detected in the control group al 8 weeks. Compared with the control group, CAV was significantly relieved, the activity of PPARy was significantly elevated, the activity of NF k-B was significantly decreased, levels of intragraft monocyte chemoattractant protein-1 and interferon-inducible protein-10 were significantly reduced in the low-dose and high-dose fish oil-treated groups (P < 0.001, P < 0.05), especially in the high-dose fish oil-treated group (P < 0.05). There was no significant difference in expression of chemokine receptors CXCR3 in the low-dose and high-dose fish oil-treated groups and control group. Our results demonstrated that n-3 fatty acids from fish oil can attenuate CAV development, possibly through activating PPARy and subsequently inhibiting the NF-kB activation, the chemokines secretion and its receptor expression in a dose-dependent fashion in rat models.

Objective To investigate the diagnostic value of DNA ploidy analysis combined with immunocytochemistry p16/ki-67 double staining in cervical high grade squamous intraepithelial neoplasia(HSIL) and cervical squamous cell carcinoma(SCC).Methods A total of 73 cases of cytological tests were randomly collected.Among them,53 cases were small DNA ploidy abnormal cells and 20 cases were DNA ploidy negative.The p16/Ki-67 results were detected by immunocytochemistry double staining.With the pathological results as the golden standard,the diagnostic values of DNA ploidy analysis and DNA ploidy analysis combined with p16/Ki-67 double staining in HSIL + was contrastively analyzed by pathologic results.Results Among 20 samples of DNA ploidy negative,the p16/Ki-67 double staining results all were negative.The positive predictive value of DNA ploidy analysis for HSIL + was 34.62％.The sensitivity of DNA ploidy analysis combined with p16/Ki-67 double staining for HSIL + was 84.62％,and its specificity was 92.31％,the positive predictive value was 78.57％ and the negative predictive value was 94.74％,which were significantly higher than those of DNA ploidy analysis(P＜0.05).Conclusion p16/Ki-67 double staining can significantly im prove the prediction value of HSIL.The DNA ploidy analysis combined with p16/Ki-67 double staining is an effective method for predicting HSIL +,which is suitable for the implementation in the areas with lack of medical resources.

Objective To investigate the distribution of Leptotrombidium deliense among different small mammal hosts in some areas of Yunnan province. Methods A field survey was carried out in some counties of Yunnan province and the small mammal hosts were captured, using mouse cages and traps with baits. Chigger mites on the surface of two auricles were scraped off by a bistoury, and then preserved in 70% ethanol. Every specimen of the chigger mites on the slides was finally identified into species under a microscope. Some conventional statistical methods were adopted to calculate all the collected chigger mite species and the constituent ratios of Leptotrombidium deliense in different areas and on different hosts, together with its prevalence and mean abundance on different hosts. Results A total of 10 222 small mammal hosts were captured from 19 counties and identified as 11 families, 34 genera and 62 species in 5 orders, and 92 990 individuals of chigger mites were collected from the body surface of these small mammal hosts. All the collected chigger mites were identified as 3 subfamilies, 22 genera, and 225 species. Meanwhile, Leptotrombidium deliensee only accounted for 1.659% of the total. The host specificity of Leptotrombidium deliense was very low and 1544 individuals of Leptotrombidium deliense collected from 8518 small mammal hosts belonged to 6 families, 13 genera and 19 species in 3 orders. Our results showed that Leptotrombidium delienses were mainly collected from Insectivora and Rodentia. Leptotrombidium deliense had long been considered as the dominant species of chigger mites and the main vector of tsutsugamushi disease in Yunnan province of China, but our results seemed not thoroughly supporting this point of view. Conclusion Traditionally, Leptotrombidium deliense was the dominant species and the main vectors of scrub typhus in Yunnan province. However, based on our results, the above view might be true in some local places and the composition of chigger mites and the main vector of tautsugamushi disease might be different in regions and habitats in Yunnan province.
