Selective salpingogram(SSG)and hysterosalpingography(HSG)have achieved fairly reliable diagnostic value. SSG and transcervical fallopian tube recanalization(T-FTR)possess rather credible therapeutic value,long-term effect and low risk. Recanalization rate and pregnancy rate,combining with the measurement of tubal perfusion pressures(TPP)and development of ultrasonic technology,can evaluate the therapeutic effect and safety more generally and objectively. Researches in the future should lay emphasis on developing non-radiologic technique,promoting diagnostic veracity,reducing side effects,and establishing randomly control trials together with consolidating the standardized evaluation criteria.(J Intervent Radiol,2007,16: 714-717)

Objective:To study the curative effect of hydrotalcite combined with omeprazole in the treatment of gastric ulcer with gastric bleeding. Methods:Seventy-six patients with gastric ulcer and bleeding in the stomach were selected and randomly divided into two groups. Thirty-two patients in the control group were treated with omeprazole alone while 44 patients in the observation group were treated with hydrotalcite combined with omeprazole. The therapeutic effects were compared between the two groups. Results:The total effective rate in the observation group was 100% while that was 87. 5% in the control group,and the difference between the two groups was statistically significant(P<0. 05). The comprehensive score of symptoms of the patients in the observation group was(4. 2 ± 1. 2)while that was(6. 2 ± 1. 4)in the control group,and the difference was significant(P<0. 01). The abdominal pain,abdominal distention and belching remission time in the observation group were slightly shorter than those in the control group(P<0. 05)and the time of hematemesis and hemafecia remission was significantly shorter than that in the control group(P<0. 05). After the 3-month treatment,the re-bleeding rate in the observation group was 6. 82%,which was slightly better than that in the control group,and the difference had no statistical significance(P<0. 05). The incidence of adverse reactions in the observation group was 9. 09% while that was 6. 25% in the control group,and there was no significant difference between the two groups(P>0. 05). Conclusion:Hydro-talcite combined with omeprazole in the treatment of gastric ulcer with gastric bleeding is effective and safe.

ObjectiveTo study specific allergic IgG antibody test and its impact factors.MethodsA total of 1770 Qingdao residents were recruited in this cross-sectional study from January to October 2011.ELISA was used to test specific allergic IgG antibodies.Logistic regression was used for multifactor analysis.Results Of 1770 participants,9 individuals had insufficient data,resulting in a response rate of 99.5％.Identification rate of specific allergic IgG antibody was 60.0％ (1056/1761 ),and the most commonly seen allergic foods were crab (49.4％ ),egg (44.80％ ),ling (38.0％ ),shrimp ( 30.4％ ) and soy ( 22.2％ ).Intolerance to crab,egg,shrimp,creamery,com,and tomato showed gender difference ( x2 =18.978,P＜0.05 ).Serum level of allergic IgG antibody was increased with age [20 - 40 years:( 118.61 ±45.67) U/ml; 41-60 years:(166.57 ±55.82) U/ml; ＞60 years:(183.67 ±49.34) U/ml; x2=13.597,P＜0.01].In logistic regression,difference between individuals with normal body weight and obesity population ( OR =1.897,95％ CI 1.215 - 2.578 ) or between those with or without allergic history ( OR =0.780,95％ CI 0.648 - 0.912) was found.Conclusions Impact factor of food intolerance includes gender,age,constitution and body mass index.Six kinds of food intolerance are more common in women.41 -60 year group shows peak of food intolerance.No exposure to allergic food and antianaphylaxis may reduce the risk of food intolerance.

Objective To explore relevant factors of hyperthyroidism with periodic paralysis of hypokalemic (TPP).Methods The clinical data of 112 cased with hyperthyroidism complicated periodic paralysis of hypokalemic were retrospectively analyzed and to analyze the relevant factors. Results Compared to control group, the hyperthyroidism with periodic paralysis group had no obvious differences in general factors ( P ＞ 0. 05 ), but had obvious difference in Gender( P ＜0. 05 ) ;Compared to control group, the hyperthyroidism with periodic paralysis group had obvious differences in induction factors(P ＜ 0. 05);Compared to recurrent group, the incipient group had no obvious differences in several factors( P ＞0. 05) ,but had obvious difference in hyperthyroidism medical history over one year( P ＜0. 05) ; Hyperthyroidism with periodic paralysis was strongly associated with hypokalemia, age, gender, tiredness, getting a cold, satiation and hyperthyroidism genetic history ( P ＜ 0. 01 ). Conclusion The relevant factors of hyperthyroidism with periodic paralysis were hypokalemia, gender, tiredness, getting a cold, intemperance, satiation and hyperthyroidism medical history.

Objective To investigate the role of erythrocyte complement receptor type 1 (CR1) in the pathogenesis of chronic urticaria.Methods Venous blood samples were collected from 59 patients with chronic urticaria (including 14 cases of dermatographism and 45 chronic idiopathic urticaria) and 29 healthy human controls.Flow cytometry was carried out to quantify the expression level of CR1,and double-antibody sandwich enzyme-linked immunosorbent assay to determine the serum level of immunoglobulin E (IgE),complement C3,C4 and 50％ complement hemolytic activity (CH50).Differences in these parameters were analyzed by one-way ANOVA and independent samples t-test,and correlation between these paramenters by Pearson correlation analysis.Results The expression level (expressed as mean fluorescence intensity per 10 000 erythrocytes) of CR1 was significantly higher in patients with dermatographism and chronic idiopathic urticaria than in the healthy controls (35.06 ± 2.06 and 29.17 ± 1.53 vs.20.46 ± 2.57,t =4.20 and 3.33,both P ＜ 0.05),while no statistical difference was observed between the patients with dermatographism and chronic idiopathic urticaria (P ＞ 0.05).Increased total serum IgE levels were observed in patients with dermatographism and chronic idiopathic urticaria compared with the healthy controls ((769.89 ± 123.0) μg/L and (340.09 ± 29.74) μg/L vs.(107.63 ± 88.79) μg/L,t =5.58,5.85,both P ＜ 0.05),and in patients with dermatographism compared with those with chronic idiopathic urticaria (t =3.49,P ＜ 0.05).For patients with chronic urticaria,there was a statistical difference in the expression level of CR1 between individuals (n=22) with total serum IgE levels ranging from 0 to 240 μg/L and those (n =17) higher than 500 μg/L (24.45 ± 10.83 vs.33.09 ± 11.86,t =3.33,P＜ 0.05).The total serum IgE levels were positively correlated with the level of CR1 (r =0.27,P ＜ 0.05),but uncorrelated with that of complement C3 (r =0.16,P ＞ 0.05) or C4 (r =-0.08,P＞ 0.05).The level of complement C3 was positively correlated with that of C4 (r =0.54,P ＜ 0.01).One-way ANOVA revealed no significant difference in the serum levels of complement C3,C4,or CH50 between the patients with dermatographism,patients with chronic idiopathic urticaria and healthy controls (all P ＞ 0.05).Conclusion CR1 is abnormally expressed in patients with chronic urticaria.

BACKGROUND:Retinal diseases are caused by damage or apoptosis of the retinal cel s and lack of ideal treatment. Induced pluripotent stem cel s have self-renewal ability and differentiation potential. A new potential source from which to produce stem cel s as a therapeutic platform for the treatment of retinal diseases and avoid ethics issues is the research focus currently.
OBJECTIVE:To review recent advancement of induced pluripotent stem cel s and the potential utility for retinal diseases.
METHODS:The first author searched related articles published from 2006 to 2011 by computer retrieval in PubMed database using the keywords of“induced pluripotent stem cel s, retinal, photoreceptor, retinal pigment epithelium, retinal ganglion cel”in English. Final y, total y 42 papers were involved.
RESULTS AND CONCLUSION:Induced pluripotent stem cel s can be induced to differentiate into retinal cel s which have a possibility to be used as donor cel s for transplantation therapies. Patient-derived induced pluripotent stem cel s can be used as disease models for mechanistic studies and drug screening. It is a promising therapy for retinal degenerative diseases. However, some problems stil remain, such as risk of teratoma formation and low efficiency of somatic cel s to be successful y induced into induced pluripotent stem cel s. It stil requires further more studies.
