Inflammatory bowel disease(IBD),the precise etiology of which remains unknown,is comprised of two forms of chronic intestinal inflammation,ulcerative colitis and Crohn's disease.Recent researches suggest that angiopoiesis plays an important role in the development of IBD.Many cytokines can enhance angiopoiesis,such as fibroblast growth factor-2,interleukin-8,platelet-derived growth factor,transforming growth factor-? and particularly vascular endothelial growth factor.This review summarizes the angiopoietic factors correlated with IBD.

Objective To evaluate influence of patient-controlled intravenous analgesia (PCIA) and patient-controlled epidural analgesia (PCEA) on expressions of serum inflammatory cytokines in elderly patients with hemi or whole hip replacement using cemented artificial joint. Methods Elderly patients undergoing hip replacement were selected and were divided into PCIA group and PCEA group. VAS scores were calculated at 12 h postoperatively. Patients whose VAS scores were not more than 2 at postoperative 12h were included. 30 cases in each group were finally included. Fifteen cases were randomly chosen in each group and underwent sample blood drawing for assays. Expressions of serum inflammatory cytokines were detected by ELISA , RT-PCR and Western-blot. Results Gene and protein expressions of TNF-a as well as IL-6 in group PCEA were lower and expression of IL-10 was higher than that in group PCIA. Serum level of TGb-β was higher in group PCEA detected by ELISA. There was no significant difference in expression of IL-8 between groups. Conclusions PCEA may better promote expressions of anti-inflammatory cytokines and inhibit expressions of proinflammatory cytokines. PCEA is superior in maintenance of inflammatory cytokine balance.

Objective To investigate the clinical and laboratory profiles of a patient with pustular psoriasis-like skin lesion and cerebral palsy due to biotinidase deficiency. Methods A 5 year and 4 month-old boy with biotinidase deficiency was confirmed by urinary organic acid analysis with gas chromatography/mass spectrometry (GC/MS)and biotinidase activity assay of peripheral blood. His clinical features, laboratory findings, treatment and outcome were studied. Results The boy showed difficulty in taking food after birth, gradually eczema and pustules appeared at the age of 2 months, and generalized erythema and intractable pustular psoriasis-like lesion at the age of 8 months. His intellectual development was normal with retardation of locomotor system. He had muscular dystonia at the age of 6 months. Physical examination showed generalized pustular psoriasis-like lesion, generalized paralysis, hypertonic contracture of extremities, sparseness of scalp hair and severe malnutrition. Routine laboratory tests showed a mild anemia, metabolic acidosis and elevation of plasma creatine phosphokinase. Increased excretion of urinary lactate, pyruvate, 3-OH-propionate, propionylglycine, and 3-methylcrontonylglycine were observed. Biotinidase activity of his peripheral blood was below 0.1 pmol/min/3mm (normal 6.3-9.3 pmol/min/3mm). Biotin (10 mg/day) supplementation led to a dramatic recovery of the skin lesion. After the treatment of rehabilitation, his muscle power was also improved gradually. Conclusions Dermatological and neurological manifestations are the main features of biotinidase deficiency. Early diagnosis and biotin administration can greatly improve the clinical symptoms. Generalized pustular psoriasis-like lesion and cerebral palsy of this boy have improved after the supplementation of biotin, but he may be remained wheelchair-dependent because of delayed diagnosis.

Objective:To analyze the influence of different factors on the entropy and grayscale values extracted from the ultrasonic original radio-frequency signals of normal human gastrocnemius.Methods:The ultrasonic original radio-frequency signals of 10 healthy men and 10 healthy women admitted to the Department of Ultrasound of First Affiliated Hospital of Nanjing Medical University from October to December 2019 in natural ankle joint position, maximum plantar flflexion and maximum dorsiflflexion position were collected, and the entropy and grayscale values were obtained by processing these signals with MATLAB software to analyze the differences of parameters in different positions and sections, and to discuss the influence of age, gender and BMI on them.Results:Comparison of the values between different sections: the differences between longitudinal extraction entropy values and transverse extraction entropy values at the maximum dorsiflexion position were statistically significant ( P<0.05), the differences between longitudinal extraction grayscale values and transverse extraction grayscale values at the natural position were statistically significant ( P<0.05) and both of values extracted in the longitudinal plane were higher than those extracted in the transverse plane. Comparison of the values among different positions of the ankle joints: the values of the maximal metatarsal flexion were statistically different from those of the natural position and the maximal dorsiflexion ( P<0.05), and the values of the maximal metatarsal flexion were the lowest, while the entropy and gray values of the natural position and the maximal dorsiflexion were not statistically different ( P>0.05). There was no significant difference in ultrasonic characteristic parameters between different genders and different age groups ( P>0.05). There was no correlation between BMI and characteristic parameters ( P>0.05). Conclusions:The entropy and grayscale values extracted from the original radio-frequency ultrasonic signals of healthy persons′ gastrocnemius can quantitatively reflect the difference in muscle structure from different positions and setions. As a result, this method can be considered in the quantitative evaluation of neuromuscular diseases.

The aim of this study was to conduct the preparation and pharmaceutical characterization of a new type of terbinafine hydrochloride bioadhesive film-forming gel. The viscosity of the gel of(13 299±51)mPa ·s, pH of 3. 50±0. 50, and the shearing viscosity of(196±4)g/cm2 was found. This new gel turned out to be a layer of solid film on the application site in a very short time. The remaining solid ratio of the resulting film was estimated to be(50. 74±2. 81)%; the tensile strength was(1. 17±0. 21)MPa; and the breaking elongation was(21. 42±3. 24)%. In vitro release behavior of terbinafine hydrochloride from the film was investigated according to the paddle over disk method in ChP2010. Terbinafine hydrochloride released continuously for 10 h from the film. Improved Franz type diffusion cells were used in vitro transdermal studies by the application of excised minipigs skins. No penetration of drug into the receptor medium across the skin existed and so it could imply the safety for local application. It was found that(93. 05±5. 66)% of drug stayed on the skin surface while(1. 15±0. 85)% entered into the skin, which was beneficial for the treatment of superficial skin fungal infection.

Objective To investigate the clinical effect of five-step sequential method for hemorrhagic radiation cystitis.Methods From April 2015 to April 2018,512 cases of hemorrhagic radiation cystitis patients in 6 provincial tumor hospital were retrospectively analyzed.12 cases were male patients,and 497 cases were female.Patients'average age was (60.1 ± 8.2) years (53-71 years).Hematuria appeared in 2.9 years on average after radiotherapy(ranged 0.5 to 13 years).According to the severity of hematuria,480 patients were classified as mild and 32 patients as severe.The step 1 was drug conservative symptomatic treatment.Thrombin solution or sodium hyaluronate was used for bladder perfusion in step 2.The step 3 was transurethral electrocoagulation.The step 4 was interventional embolization.The step 5 was hyperbaric oxygen therapy.Mild patients were treated from the first step,and the severe patients were treated rom step 3,and combined with step 1.Overactive bladder symptom score (OABSS) was used to assess the improvement of patients'symptoms.Results No obvious complications occurred in step 1,2,3,5.Mild hip pain occurred at step 4.Recurrent hemorrhage rate were 6.7％ (2/30) in mild patients group and 10.5％ (2/19) in severe respectively in step 4.The total effective rate of step 1 in mild patients group was 65.2％ (313/480),step 1 + 2 was 84.2％ (404/480),step 1 + 2 + 3 was 95.6％ (459/480),step 1 + 2 + 3 + 4 was 98.3％ (472/480),and step 1 +2 +3 +4 +5 was 100％ (480/480).The effective rate of step 3 + 1 treatment was 59.4％ (19/32) in severe patients group,step 3 + 1 + 4 was 68.8％ (22/32),and step 3 + 1 +4 +5 was 100％ (32/32).The OABSS scores of mild and severe patients decreased after treatment (P＜0.01).Condusion Five-step sequential therapy could be an effective method for the treatment of hemorrhagic radiation cystitis.
