The clinical diagnosis value and significance of serum sH2a level on early hepatic fibrosis degree / 中华实验和临床病毒学杂志

Objective@#We aimed, in our prospective study, to assess the predictive value of serum non-invasive and biochemical markers for clinical diagnosis of significant fibrosis (including early stages).@*Methods@#We measured sH2a levels in serum, comparing with routine liver function markers. We compared blindly pretreatment serum samples from a cohort of hepatitis B patients without non-alcoholic fatty liver disease(NAFLD), which had histological grades of liver fibrosis, with NAFLD individuals and CHB with NAFLD patients. Statistical analysis was by Student′s t test, and receiver-operating characteristic (ROC) curves were drawn.@*Results@#ROC curves showed that serum sH2a had greater diagnostic performance than routine liver function markers compared with histological grades of liver fibrosis(S0, S1-2, S3-4). ROC curves showed that using a sH2a cut-off point of 0.79 was with highest sensitivity as 63% and highest specificity as 80%. And sensitivity as 96.7% and specificity as 75.5% when using a sH2a cut-off point of 0.77.@*Conclusions@#sH2a has the potential to be a uniquely sensitive and specific novel marker for liver fibrosis and function.

Effects of Compound Ligusticum chuanxiong Drop Pill on Hemorheology and Blood Gas in Model Rats with Diabetic Nephropathy / 中国药房

OBJECTIVE:To explore the effects of Compound Ligusticum chuanxiong drop pill on hemorheology and blood gas in model rats with diabetic nephropathy(DN). METHODS:60 rats were randomly divided into normal control group,model group, positive control group [Irbesartan tablet,0.013 g/(kg·d)] and Compound L. chuanxiong drop pill high-dose,medium-dose,low-dose groups [0.4,0.2,0.1 g/(kg·d)],10 in each group. Except for normal control group,rats in other groups were given high-sugar high-fat feed and intraperitoneally injected streptozotocin to reduce DN model. After 7 d modeling,rats in each group received relat-ed drugs intragastrically,once a day,10 mL/kg;normal control group and model group received equal volume of purified water in-tragastrically. After 64 d,hemorheology indicators [whole blood viscosity(high-shear,medium-shear and low-shear),plasma viscosi-ty,whole blood reduced viscosity] and blood gas indicators(carbon dioxide partial pressure,oxygen partial pressure,hemoglobin content,oxygen saturation,ratio of oxygenated hemoglobin to total protein) of rats were determined,hematoxylin-eosin staining was used to observe the pathological changes in kidney tissue. RESULTS:Compared with normal control group,hemorheology indi-cators and carbon dioxide partial pressure in model group were significantly increased(P<0.05 or P<0.01),oxygen partial pres-sure,hemoglobin content,oxygen saturation,ratio of oxygenated hemoglobin to total protein were significantly decreased(P<0.05 or P<0.01),with severe kidney damage. Compared with model group,except the improvement of carbon dioxide partial pressure, oxygen partial pressure,hemoglobin content in rats were not significant in Compound L. chuanxiong drop pill low-dose group,the above-mentioned indicators in other medicine groups were significantly improved(P<0.05 or P<0.01);the kidney tissue damage was improved to varying degree. CONCLUSIONS:Compound L. chuanxiong drop pill can significantly improve the hemorheology indicators of DN model rats,reduce blood viscosity,improve microcirculation and capacity of the blood to transport oxygen,and has certain improvement effect on kidney tissue morphology of DN rats.

Mycobacterium Tuberculosis in Spinal Tuberculosis

Even in an era of remarkable medical advances, there is an issue of why tuberculosis remains in the list of disastrous diseases, afflicting humans and causing suffering. There has not been a plausible answer to this, and it has been suggested that clinicians and medical scientists could presently not win the war against the tubercle bacilli. With regards to this issue, based on the authors' own clinical and research experiences, in this review, the available literature was revisited in order to address the raised questions and to provide recent information on characteristics of tubercle bacilli and possible ways to more effectively treat tuberculosis.

Clinical features and prognosis of conjunctival lymphoid hyperplasia / 中华实验眼科杂志

Background Primary conjunctival lymphoid hyperplasia exhibit atypical clinical symptoms and easy to cause misdiagnosis and mistreatment.Understanding the clinical characteristics of primary conjunctival lymphoid hyperplasia is of an important clinical significance.Objective This study was to analyze the clinical characteristics and therapeutic outcome of patients with primary conjunctival lymphoid hyperplasia.Methods The medical records of 20 patients with primary conjunctival lymphoid hyperplasia who was treated in Beijing Tongren Hospital from January 2012 to December 2014 were retrospectively analyed.The age,symptoms,therapy,prognosis,histopathological features and immonochemistry results were reviewed,and the treating approach targeting to different types of conjunctival lymphoid hyperplasia was evaluated.The fellow-up duration was 1-2 years.Results Age of the patients ranged from 27 to 83 years old.The lesions were classified as benign lymphocytic hyperplasia,atypical lymphoid hyperplasia and lymphoma.Majority of lesions located in fornix conjunctiva tissue (90％).Follicle-like appearance was seen in the benign lymphocytic hyperplasia,and pink elavation was exhibited at the bulbar conjunctiva in the atypical lymphoid hyperplasia.A diffuse salmon fish like appearance in conjunctiva was the primary feature of conjunctival lymphoma.Histopathological examination showed that conjunctival benign lymphocytic hyperplasia had follicle-like tissue in lesions,atypical lymphoid hyperplasia exhibited diffuse lymphocyte filtration,and conjunctival lymphoma appeared monocyte filtration.The 3 tpyes of lesions also could be differentiated by immunochemistry.The medicine was applied in the eyes with benign lymphocytic hyperplasia,and the combination of resection of lesions with conjunctival tissue or amniotic membrane transplantation was used for the atypical lymphoid hyperplasia or lymphoma eyes.No recurrence of the lesions was found during fellow-up duration.Conclusions The clinical manifestations of conjunctival lymphoid hyperplasia lesions are varied,and it is easy to be confused with chronic ocular surface diseases.Pathology and immunochemistry are helpful for the differential diagnosis.The treating regimen is dependent on the lesion type.Most patients have a favorable prognosis with treatment.

Effect of recombinant human interferon α1b on lung tissue pathology and Janus kinase(JAK)/signal transducer and activator of transcription (STAT) signal pathway in mice infected by respiratory syncytial virus / 中华实用儿科临床杂志

Obgective To investigate the impact of different ways and doses of recombinant human interferon o1b(rhIFN-α1b) on antiviral effect on respiratory syncytial virus(RSV)-effected mice and signal pathway of JAK/ STAT.Methods Forty-eight mice were divided randomly into 6 groups,negative control group,RSV-infection model group,12.5,25.0,50.0 μg rhIFN-α1 b atomization inhalation of intervention group,and 12.5 μg rhIFN-α 1 b injection of intervention group.After continuous drug therapy for 5 days,the left lung tissues of mice were aseptically dissected in the sixth day.Then it were observed lung tissue pathology changes by optical microscope,and expression of STAT1 and STAT2 protein with laser scanning confocal microscopy.Results It was observed that RSV-infection model mice's lungs had significant inflammatory injury under light microscope.After treatments of rhIFN-α 1b,it showed that the mice lung tissue had recovery of inflammation on different degrees.The group of inhaled rhIFN-o1b 50.0 μg was damaged on lightest degree.There were statistically significant differences between each group (all P ＜ 0.05).The expression of STAT1 and STAT2 protein in RSV-infection model mice's lungs decreased remarkably under fluorescene microscopy.Treatments of rhIFN-α 1b increased the expression of STAT1 and STAT2 inhibited by RSV-infection.The expression of STAT1 and STAT2 protein of the inhaled rhIFN-α1b 50.0 μg group increased significantly.The differences between groups were statistically significant(all P ＜ 0.05).Conclusions rhIFN-α 1 b played an important role in anti-RSV effects,simultaneously,it could improve the activity of JAK/STAT signal pathway inhibited by RSV-infection.The treatment effect of rhIFN-α 1b deliveried by atomization inhalation was better than that of intraperitoneal injection.And curative effect is proportional to the atomization inhalation dose within a certain range.
