OBJECTIVETo explore the relationship between ulcerative colitis (UC) and lung injuries by assessing their clinical manifestations and characteristics.

METHODSFrom July 2009 to April 2012, 91 UC patients presenting to Longhua Hospital who met the established inclusion and exclusion criteria were enrolled in this retrospective study. According to the scores of disease activity index, the patients were divided into the mild, moderate, and severe groups. Meanwhile, the records of pulmonary symptoms, chest X-ray image, and pulmonary function were reviewed.

RESULTSSixty-eight (74.7%) patients had at least 1 pulmonary symptom, such as cough (38.5%), shortness of breath (27.5%), and expectoration (17.6%). And 77 (84.6%) had at least 1 ventilation abnormality. Vital capacity value was significantly lower in the severe group than that in the mild group (91.82%±10.38% vs. 98.92%±12.12%, P<0.05).

CONCLUSIONSLung injury is a common extraintestinal complication of UC. According to the theory in Traditional Chinese Medicine that the lung and large intestine are related, both the lungs and large intestine should be treated simultaneously.

Objective To explore the effects of Kangshuaiyizhi capsule on ChAT/AchE and NE, DA and 5-HT levels in the brain tissue of aging model rats, and explore its effect of protecting cerebral function. Methods Totally 72 rats were randomly divided into normal group and model group. The subacutely aging model rats were made by injecting D-gal (0.125 g/kg) into abdominal cavity continually, then aging rats were divided by random number table into model group, Naofukang group and Kangshuaiyizhi high-, low-dose group. After intervented with correspongding drugs for 60 days, activity of ChAT and AchE, cerebral cortex NE, DA, and 5-HT levels were detected. Results Activity of AchE was much higher (P<0.05), but level of ChAT, NE, DA and 5-HT in model group were significantly downregulated compared with normal group (P<0.05). After treated with Kangshuaiyizhi capsule, activity of AchE was downregulated, ChAT, NE, DA and 5-HT levels were significantly upregulated (P <0.01, P <0.05). Conclusion Kangshuaiyizhi capsule can regulate cholinergic and monoamine neurotransmitter levels in the brain tissue of aging model rats, and play a very important role in protecting cerebral function.

Objective To investigate the effect of solute cartier organic anion transporter family, member 1B1 (SLCOIBI) gene variants on the response to therapy with repaglinide in type 2 diabetes. Methods 100 newly-diagnosed type 2 diabetic patients were treated with repaglinide during a course of 48 weeks. Anthropometrie parameters and indices related to glucose metabolism were measured periodically. Genotypes of SLCO1B1 D130N and V174A were detected by PCR-restriction fragment length polymorphism (RFLP) and sequencing respectively. Results Eighty-nine patients accomplished the 48-week follow-up visits. D130N variant in SLCO1B1 gene was associated with repaglinide treatment, DD genotype had better HbA1C lowering effect than N allele carrier [△HbA1C: (-2.29±0.23) % vs (-1.49±0.21)%, P<0.05]. No association was detected between D130N and the other effects of repaglinide on glucose metabolism related phenotypes. Conclusion D130N variant in SLCO1B1 gene is associated with the response to repaglinide treatment in patients with type 2 diabetes. DD homozygotes had a better effect than N allele carriers.

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 roles of different effective dosages of morphine on incision pain in rats.Methods Clean-degree male SD rats were randomly allocated to three groups(n=11): normal saline group(NS group),low-dose morphine group(LM group,0.6 mg/kg) and high-dose morphine group(HM group,6 mg/kg).After administration of morphine twice at 30 min interval,the incision pain models of rats were prepared according to the Brennan's method.Morphine was administered once again following the operation,while the NS group was administrated isovolumic normal saline.Then the mechanical threshold of rats was detected with von Frey filaments from the pre-operation to the 8th postoperative day,and the hyperalgesia induced by morphine on the praxiology level was explored. ResultsThe values of mechanical threshold postoperation in each group were significantly lower than those of the baseline.The mechanical threshold of HM group was significantly higher than the NS group on the second day postoperation(P

Objective To explore the changes in inflammatory reactions in tail-suspension mice infected by Klebsiella pneumoniae from spaceflight.Methods Tail suspension was used to simulate the physiological effects of microgravity.C57BL/6 mice were randomly divided into control (Con),control+K.pneumoniae T16-169 (Con+T16-169),tail suspension (TS) and tail suspension+K.pneumoniae T16-169 (TS+T16-169) groups.The level of inflammatory cytokines TNF-α,IL-6 and IL-1β mRNA in lung tissue and the plasma cytokine concentration were detected by RT-qPCR and xMAP technology,and HE staining was used to represent the morphological changes in lung tissue.Results Compared with the control group,the expression of inflammatory cytokines in lung tissue and plasma concentrations of all experimental groups were increased,and the difference in TS+T16-169 group was the most significant (P<0.01 or P<0.001).HE staining showed that the lung tissues in Con+T16-169 and TS+T16-169 groups were damaged in different degrees,and the damage of TS+T16-169 group was the most serious.Conclusion The K.pneumoniae from spaceflight significantly increases the expression of inflammatory cytokines in lung tissue and plasma concentrations after infecting tail-suspension mice,and induces more serious damages to the lung tissue,which suggests that inflammatory reactions can be increased in tail suspension mice infected by K.pneumoniae from spaceflight.

Objective: To investigate the correlation between the histogram parameters of apparent diffusion coefficient (ADC) with clinico-pathological characteristics of rectal adenocarcinoma. Methods: The preoperative magnetic resonance imaging data of 64 patients diagnosed by pathology as rectal adenocarcinoma were collected. OmniKinetics software was employed to draw the outline of the ADC image on each layer of the tumor. The whole-volume ADC histogram parameters were automatically calculated with the post-processing software, including the minimum (ADCmin), maximum (ADCmax), median (ADCmedian), mean (ADCmean), 10th percentile (ADC10), 25th percentile (ADC25), 75th percentile (ADC75), 90th percentile (ADC90), skewness, and kurtosis. The differences in ADC parameters of tumor markers, immunohistochemical index, tumor size and lymph node metastasis were compared, and multiple linear regression was performed to analyze the correlation between the ADC histogram parameter and the clinico-pathological characteristics of rectal adenocarcinoma. Results: The ADC25 values were significantly lower in the groups of lymph node metastasis, Ki-67 ≥50%, CA199 ≥37 U/ml and CA72-4 ≥8.2 U/ml than those in the groups of lymph node non-metastasis, Ki-67 <50%, CA199 <37 U/ml and CA72-4 <8.2 U/ml (P<0.05 or P<0.01). The ADC75 values were lower in CD31 positive group and CD56 positive group than those in their negative groups (P<0.05). There was no correlation between skewness and clinical pathological features (P>0.05). Multiple linear regression analysis reveled that positive CD31 was significantly correlated with ADCmean, ADC25 and ADC75 (P<0.05), and the ADC25 showed the greatest effect on CD31 positive (standard regression coefficient was 0.210). Conclusion: ADCmax, ADCmean, ADCmedian, ADC10, ADC25 and ADC75 possess high reliability in diagnosis of rectal adenocarcinoma. Among them, ADCmean, ADC25 and ADC75 have higher correlation with tumour markers and immunohistochemical indicators, may be used as important imaging biomarkers for evaluating the prognosis of rectal adenocarcinoma.

Objective To establish a RP-HPLC method for the determination of the blood concentration of paeoniflorin which was produced by seven kinds of warming-inside drugs (WID) being used with the promoting-blood drugs (PBD) individually and to explore the mechanism of PBD and WID compound prescription. Methods The blood concentration of peaoniflorin in mouse plasma was determined by HPLC after ig seven kinds of WID being compatible with Radix Paeoniae Rubra (RPR) to mice separately. Results Fructus Piperis (FP), Cortex Cinnamoni (CC), Fructus Evodiae (FE), Fructus Foeniculi (FF), and Pericarpium Zanthoxyli (PZ) compound prescription with RPR can increase the blood concentration of paeoniflorin in different degrees (P

To retrospectively analyze the clinical data of a child with congenital broncho-bile duct fistula(CBBF) in Guiyang Children′s Hospital in June 2019.A female, aged 7 years and 6 months old, patient presented cough with a large amount of yellow green mucus.The main clinical manifestation was recurrent pulmonary infection after birth.After the fistula was found by electronic bronchoscope, doctors cooperated with imaging department, anesthe-siology department and pediatric surgery department.After treatment, the child recovered and discharged.There are few reports on CBBF.This study suggested that, in view of the refractory pneumonia with recurrent pulmonary infection and yellow green sputum after birth, and that the effect of anti-infection treatment was poor, clinicians should pay attention to the CBBF, take bronchoscopy as soon as possible, and make early diagnosis by combining with imaging technology, thus formulating a reasonable diagnosis and treatment plan under multidisciplinary cooperation, so as to improve the diagnosis and treatment of this rare disease clinical diagnosis and treatment level, and reduce missed diagnosis and misdiagnosis as well.

Objective To compare the differences of metabolic syndrome (MS) prevalence by using four working definitions and their relationship with obesity-related indicators in first-degree relatives of type 2 diabetes mellitus pedigrees. Methods Totally, 2 372 first-degree relatives from 715 type 2 diabetic pedigrees were selected in this study. Complete laboratory data, including blood pressure, lipid profile and plasma glucose, were collected. The prevalence rates of MS and obesity of four definitions, as defined by National Cholesterol Education Program Adult Treatment Panel Ⅲ (ATPⅢ) in 2005, International Diabetes Federation (IDF) in 2005,Chinese Diabetes Society (CDS) in 2004 aml Joint Committee for Developing Chinese Guidelines on Prevention and Treatment of Dyslipidemia in Adults (JCDCG) in 2007,were analyzed. Results (1)The prevalence rates of MS were 45.40% ,38.74% ,25.08% and 39.29% aecording to four definitions respectively. The prevalence rates of MS were higher in females than in males by using ATPⅢ and IDF definitions (both P<0. 01). (2)The common comhinations of metabolic abnormality was dyslipidemia, hypertension, obesity and hyperglycemia by using four definitions,except in females by using CDS definition. (3)The prevalence rates of obesity were 58.18% ,58.18% ,33.90% and 42.96% acconling to the four definitions respectively. The prevalence rates of MS in obese subjects were 66.59% ,66.59% ,54.85% and 68.99% according to four definitions respectively. (4) Applying the cutoff point for abdominal obesity according to ATPⅢ, IDF and JCDCG definitions, the prevalence rates of abdominal obesity in subjects with body mass index (BMI) <25 kg/m2 were respectively 28.58% and 16.78%, being higher in females than in males(38.90% vs 15.02% ,21.01% vs 11.22% ,both P<0. 01). Conclusion (1)There is significant familial aggregation of MS and obesity,and the first-degree relatives of type 2 diabetic patients are high risk populations. (2) Waist circumference rather than BMI taken as a discriminating component of obesity in MS seems to be clinically more helpful to the early identification and prevention of MS.
