Objective To investigate the clinical characteristics and chronological change of ulcerative colitis(UC) in the Chinese PLA General Hospital in near 16 years. Methods Patients diagnosed with UC during the period from 1994 to 2009 in the Chinese PLA General Hospital were registered and their clinical profiles were analyzed. Results From 1994 to 2009, of 525 patients diagnosed with UC, with a median onset age of 42 years. The predominant form of UC was extensive colitis, which affected almost 33.3% (175/525), left-sided colitis was present in 21.3% (112/525) and rectum was present in 12.4%(65/525). The chronic relapsing type of UC was the most common (69.0%, 362/525 ), followed by the initial onset type (18. 1%, 95/525 ), chronic continuous type with intermittent exacerbations (9.7%,51/525), and acute fulminant type (3. 2%, 17/525 ). Two hundred and twenty-one patients (42. 1%,221/525) were graded as mild, 162 (30.9% , 162/525) as moderate, and 142(27.0%, 142/525) as severe UC. The proportion of mild colitis and rectum was significantly higher in patients with an onset age of over 60 years, compared with those with an onset age of less than 30 years( P ＜0. 05 ). The proportion of UC patients with old age onset ( P ＜ 0. 05 ), male sex ( P ＜ 0. 01 ), mild colitis ( P ＜ 0. 01 ), rectum ( P ＜0. 01 ) , relapse-free type ( P ＜ 0. 01 ) demonstrated a chronological increase from 1994 to 2009.Conclusions The distinctive clinical features and chronological change were seen in UC patients in recent years. Compare to those with an onset at less than 30 years, the proportion of mild colitis and rectum was significantly larger in patients with an onset at over 60 years of age, and the proportion of UC patients with old age onset, male sex, mild colitis, rectum, relapse type were less.

Background The tissue-engineered cornea is becoming the hot spot in the ophthalmologic field,while the research of corneal substitute is in the ascendant,because it is more similar to the corneal morpha and easy to survive in vivo.Objective This study was to investigate the biocompatibility of recombinant human type-Ⅲ collagen/poly9 ( 3-( methacryloylamino ) propyl dimethyl ( 3-sulfopropyl ) ammonium hydroxide ) ( PMPDSAH ) interpenetrating polymer network (IPN) (RHC-Ⅲ/PMPDSAH IPN) hydrogel as a tissue-engineered cornea in rabbit eye and its feasibility as the corneal substitute.Methods One hundred and eight rabbits were randomly divided into experimental group( 90 rabbits) and normal control group ( 3 rabbits),and 15 rabbits ( 30 eyes ) used as the donor corneas.RHC-Ⅲ/PMPDSAH IPN,NGF PMPDSAH IPN and corneal grafts were lamellarly transplanted into the right eyes in RHC-Ⅲ/PMPDSAH IPN group,NGF PMPDSAH IPN group and allograft group respectively.The corneal transparency and neovascularization were examined and scored under the slim lamp and compared among three groups using Kraskal-Wallis H test.The corneal epithelization time was observed and compared among these three groups using one way analysis of variance and LSD-t test.The histological examination of corneas was performed at the 3rd day,1st and 2nd week,1 st,3rd and 6th month after the surgery.The immunohistochemistry was used to detect the expression of K3 in cornea at the 6th month.Results The grafts were well attached in RHC-Ⅲ/PMPDSAH IPN group,NGF PMPDSAH IPN group and allograft group,and no rejection reaction was found throughout 6-month following up.Compared with normal control group,no significant differences were found in the scores of corneal opacification and neovescularization in these three groups (x2 =4.34,P =0.23 ;x2 =2.60,P =0.46 ) at the 6th month.NGF PMPDSAH IPN group achieved reepithelialization in (4.97±0.63) days and was obviously shorted than that in RHC-Ⅲ/PMPDSAH IPN group and allograft group ( t =11.97,P =0.00; t =5.80,P =0.00).The re-epithelialization time in RHC-Ⅲ/PMPDSAH IPN was (6.86±0.71) days,and that of allograft group was (5.87±0.43 ) days,showing a significant difference ( t =6.32,P =0.00).Hematoxylin-eosin staining results demonstrated that implanted materials integrated into the host corneal tissue well and support corneal epithelialization.Part of the material degraded at the 2nd week and degraded completely 1 month later.Regular alignment and distribution of collagen fibers were seen in the regenerated cornea and were similar to those of the normal stroma in 6 months.Immunohistochemistry showed the positive expression of keratin-3 in corneal epithelial cells.Conclusions RHC-Ⅲ/PMPDSAH IPN has a good biocompatibility without toxicity to corneal tissue.Furthermore,NGF can promote the corneal wound-healing and re-epithelialization.The material can be used as safe and reliable corneal substitute after improving the mechanical strength.

Objective To find out the importance of human bocavirus (HBoV) as an infectious agent for population in Beijing, China. Seroprevalence study was conducted by using expressed recombinant major capsid VP2 protein as an antigen.Methods Serum specimens collected from infants and children who visited the Children's Hospital Affiliated to the Capital Institute of Pediatrics for health check-up and adults visiting the Xuanwu Hospital, Beijing for diseases other than respiratory infections from April 1996 to March 1997 were used for the investigation. The major capsid protein VP2 from HBoV was expressed in E. coli strain BL21 (DE3) with the transformed PET30b vector inserted with full-length VP2 gene of HBoV and the specific antigenicity of this expressed protein was validated by previous study. Western blotting was used to detect specific IgG antibody against HBoV in collected serum specimens diluted to 1:200. Mock expressed protein was E. coli cells strain BL21 (DE3) with the transformed PET30b vector without insert. Anti-His monoclonal antibody and rabbit anti-HBoV VP2 polypeptides hyper-immune serum were used as positive control for antibody detection.Results Out of 677 serum specimens tested, 400 (59.1% ) were positive for HBoV by Western blotting. About 45.3% (34/75) of the newborns under 1 month of age had anti-HBoV antibodies, and antibody positive rates were decreased in age groups of 1 and 2 months (41.4% and 31.3%, respectively) then increased in the following ages from 6 months to 7 years old ( from 45.6% to 69.7% ). The antibody positive rates were maintained at a relatively constant level ( about 70% ) in the age groups from 7 years to 40 years of age and became lower ( 61.8% - 62. 8% ) in those over 50 years.Conclusions The high seroprevalence of antibody against recombinant HBoV VP2 protein and early age antibody acquisition indicate that HBoV has been circulating in population of Beijing, China as early as in 1996 and most of children had been exposed to HBoV by the age of 7 years. Infants under the age of 6 months were susceptible to this virus.

Spleen kidney Yang deficiency (SKYD) diarrhea is a common syndrome in tranditional Chinese medicine (TCM). Until now, there is not an ideal SKYD diarrhea rat model for the research. In this study, we compared single factor way (method I, injecting hydrocortisone and gavaging Sennae Folium) with compound factors way(method II, gavaging adenine, improper diet, exhaustion, and gavaging Sennae Folium) on establishing SKYD diarrhea rat model. After modelling, diarrhea index, D-xylose excretory rate, NOS/cGMP signal transduction system, organ index and histopathology examination were used to evaluate the two ways. The results showed that, compared with health group, all the assessment criterias of method I and method II had significant differences (P < 0.01, 0.05). In addition, the index such as diarrhea index, NOS/cGMP signal transduction system, organ index (kidney, testis and thymus) and histopathology examination had significant differences (P < 0.01, 0.05) between method I and method II. In conclusion, the compound factors modelling method better conforms to the symptom of diarrhoea model caused by SKYD. This new modelling method provides a basis for studying on TCM astringents warming and tonifying the spleen and kidney, relieving diarrhea.

OBJECTIVETo evaluate the effectiveness and safety of the meridian three-combined therapy for treatment of ordinary psoriasis.

METHODSA multi-central, randomized and positive drug controlled trial was adopted, and 233 cases were divided into an observation group of 116 cases and a control group of 117 cases. The observation group was treated with thread embedding at points, blood-letting puncture on the back of ear and auricular point pressing (i.e. meridian three-combined therapy). For thread embedding, 3-4 local points such ear points as Fei (CO14), Gan (CO12), Pizhixia (AT4), Shenmen (TF4) , cephalic and symmetric points of severe parts of the limb skin were selected according to the skin lesion position, and the treatment was given once each two weeks. For ear point tapping and pressing, 3-5 points were selected in each session. And the control group was treated with oral administration of Di yin Tablets, 5 tablets each time, twice each day. After treatment of 6 weeks, the clinical therapeutic effects, the score of skin lesion area, the scores for skin lesion severity and safety were compared in the two groups.

RESULTSThe markedly effective rate was 57.8 % in the observation group and 51.3% in the control group with no significant difference between the two groups (P>0.05); after treatment the scores for both the skin lesion area and the skin lesion severity were significantly decreased in the two groups compared with those before treatment (P<0.01), and with a significant difference between the two groups (P>0.05). And the incidence rate of the adverse reaction in the observation group was significantly lower than that in the control group.

CONCLUSIONThe meridian three-combined therapy is effective and safe for treatment of ordinary psoriasis.
