Objective To investigate the treatment effect of daily low dose of sildenafil treating interstitial cystitis .Methods 68 patients with interstitial cystitis in our hospital from June , 2012 to December, 2013 were divided into observation group and con-trol group by digital randomized method, 34 cases in each group.Observation group adopted daily dose of sildenafil 0.25 g treatment every day, and control group adopted the same dose of starch placebo every day.Two groups were treated for 3 months.Curative effect, micturition number a day before and after the treatment, the maximum bladder capacity, interstitial bladder inflammation shape index and problem index score ( ICSI, ICPI) , pelvic pain and urinary frequency score ( PUF) and quality of life scores ( QOL) of two groups were compared.Results The rate of significant curative effect and total effective rate of observation group were significantly higher than that of the control group, and the difference was statistically significant (p<0.01).Micturition number every day, the maximum bladder capacity, ICSI, ICPI, PUF and QOL scores of the two groups before treatment had no statistical significant differ-ences(p>0.05).Maximum bladder capacity and QOL scores of observation group after treatment were (265.44 ±43.85) ml and (44.15 ±4.69) respectively, which were higher than the (92.45 ±25.71) ml and (22.14 ±2.97) of the control group after treat-ment and (94.12 ±23.95)ml and (22.38 ±3.18) of observation group before treatment;Urine per day, ICSI, ICPI and PUF of ob-servation group after treatment is lower than that of the observation groups after treatment and that of the control group before treat-ment, and the difference had statistically significant (p<0.05).Conclusion Daily low dose of sildenafil for treating women with in-terstitial cystitis is worthy of clinical use for it can effectively relieve clinical symptoms and improve patient's life quality.

Objective To study the clinical features and diagnostic analysis of 30 cases with refractory myco-plasma pneumonia.Methods 60 patients with mycoplasma pneumonia treated in our hospital during 2012.03 to 2014.03 were selected, and 30 cases were diagnosed as normal mycoplasma pneumonia and the others as refractory mycoplasma pneumonia.The clinical manifestations, percentage of neutrophils, peripheral blood leukocytes , C -re-active protein (CRP) level, and chest radiographic were retrospectively analyzed , and the clinical judging indicators of refractory mycoplasma pneumonia were obtained by multivariate logistic regression analysis .Results Considering the time of fever, the difference between two groups was statistically significant (χ2 =12.27, p <0.01).The differ-ence of percentage of neutrophils , peripheral blood leukocytes and CRP between the two groups were all significant (p <0.05); Logistic regression analysis showed that time of fever >10 d, CRP >40 mg /L, appearance of large high -density lung opacities were the judging indicators of mycoplasma pneumonia refractory .Conclusion Time of fever, CRP level and imaging Findings are the judging indicators of mycoplasma pneumonia refractory .

The changes of the spinal cord blood flow(SCBF),the content of TXB2 and 6-keto-PGF1a of the injured segment of the cord and other neurological manifestations were observed on a rat model of spinal cord injury(SCI)established with Allen's weight drop(50g-cm)method and the effects of indomethacin on these changes were studied.It was found that SCBF was significantly reduced in the first 2 hours after SCI and further reduced in the 4th ~ 8th hour.Increase of TXB2 was observed in the 1st hour and reached the peak in the 4th hour.The level of 6-keto-PGF1a was also increased in the 1st hour and maintained at that level for 24 hours.The changes of TXB2/6-keto-PGF1a was similar to those of TXB2.There was a negative correlation of SCHF with TXB2 content and TXB2/6-keto-PGF1a ratio.The intravenous injection of 10mg/kg indomethacin could inhibit the increase of TXB2 content and increase 6-keto-PGF1a content relatively.It could also alleviate or retard the decrease of SCBF after SCI and improve the motar function of the hind limbs of the rats.These findings suggest that indomethacin can improve SCBF and promote the recovery of neurological functions through its regulatory effects on the levels of TXB2 and 6-keto-PGF1a

This study was aimed to establish an identification method between leaflets of Dimocarpus longan and leaflets of Litchi chinensis. The leaflet morphological-venation pattern (LMVP) and quantitative analysis were reliable identification method for Chinese herbs. The results showed that the main differences of leaflets of Dimocarpus lon-gan were the eucamptodromous camptodromous pinnate venation; the secondary veins gradually changed into little near margin and a few brochidodromous; the type of tertiary vein was percurrent or reticulate. The main differences of leaflets of Litchi chinensis were brochidodromous camptodromous pinnate venation; the course of the secondary veins was sinuous or zigzag, and abruptly curved then linked; the type of tertiary vein was reticulate. With three groups of key differences mentioned above, both plants can be successfully identified from each other. The accuracy of identification results (AC) was from 98.1% to 100%. The agreement rate for observation (ARO) was from 98.5% to 100%. And the Kappa value was from 0.97 to 1.00. It was concluded that the established LMVP is simple, rapid, e-conomic and reliable in the identification between leaflets of Dimoc arp us longan and leaflets of its confused herb Litchi chinensis.

To explore the characteristics of hematological abnormalities in patients with systemic lupus erythematosus (SLE) through retrospective analysis.A total of 445 SLE patients were recruited and divided into 5 groups of low white blood cell,immune thrombopenic purpura,anemia,pancytopenia and control without hematological abnormalities.Among them,351 (78.9％) had hematological abnormalities and 94 (21.1％) without hematological abnormities.The prevalence of anemia,leucocytopenia,thrombocytopenia and pancytopenia were 56.0％ (246/445),27.6％ (123/445),13.5％ (60/445) and 8.5％ (38/445) respectively.The incidence of renal damage in anemia group was significantly higher than that in control group (P ＜ 0.01).SLE patients with hematological abnormalities had lower complement C3 levels (P ＜ 0.05) and higher systemic lupus erythematosus disease activity index (SLEDAI) (P ＜ 0.01).Anemia is the most common findings in SLE patients with hematological abnormalities who have lower complement C3 levels and higher SLEDAI.

New antibiotics with novel modes of action and structures are urgently needed to combat the emergence of multidrug-resistant bacteria. Bacterial signal peptidase I (SPase I) is an indispensable enzyme responsible for cleaving the signal peptide of preprotein to release the matured proteins. Increasing evidence suggests that SPase I plays a crucial role in bacterial pathogenesis by regulating the excretion of a variety of virulent factors, maturation of quorum sensing factor and the intrinsic resistance against beta-lactams. Recently, breakthrough has been achieved in the understanding of three-dimensional structure of SPase I as well as the mechanism of enzyme-inhibitors interaction. Three families of inhibitors are identified, i.e. signal peptide derivatives, beta-lactams and arylomycins. In this article, we summarize the recent advance in the study of structure, activity and structure-activity relationship of SPase I inhibitors.

Purpose To explore the value of three vessels and trachea view in rapid screening of aortic arch malformations. Materials and Methods 51 fetal subjects who were prenatally diagnosed with aortic arch abnormalities were enrolled, and their diagnoses were confirmed by postnatal echocardiography or autopsy results after induction. Targeted fetal cardiac examinations were conducted under obstetric ultrasound examination conditions, ultrasound images were restored and compared with sonographic features of normal aorta. Results Among the 51 fetus cases with aortic arch anomalies, right-oriented aortic arch with left subclavian artery vagus was shown in 17 cases, left-oriented aortic arch with right subclavian artery vagus in 2 cases, double aortic arch in 2 cases, aortic arch disarticulation in 6 cases, and aortic arch coarctation in 24 cases. Diagnostic accuracy of ultrasound was 94.1%. Sonographic changes were displayed in three-vessel or three vessels and trachea view in all cases. Conclusion Three vessels and trachea view plays an important prompt role in ultrasound diagnosis for fetal aortic arch abnormalities. But when it is manifested as the“1oo”sign, it will be rather difficult for the differential diagnosis of aortic arch disarticulation and severe aortic arch coarctation.

Objective To evaluate the biologic characteristics of a new type femoral stems either coated with gradient hydroxyapatite (HA) or additionally loaded with rhBMP-2. Methods Fifteen dogs were divided into 3 groups according to the implanted hip prosthesis. Each animal received hemiarthroplasty in the right hip with prosthesis made of pure Ti-6Al-4V femoral stem (Ti group), the new gradient HA-coated femoral stem (HA group) with 100 to 150 ?m hydroxyapatite coating, and the new gradient HA-coated femoral stem loaded with rhBMP-2 of 9 mg (BMP-HA group) respectively. The dogs were sacrificed at 12 weeks after operation, and labeled with tetracycline 3 of 30 mg/kg days prior to sacrifice, and then the histological changes of the tissue surrounding the prosthesis were evaluated. The radiographic examinations were taken before and after sacrifice. Results On radiographic examination, local radiolucent line around the prosthesis was observed only in one specimen in Ti group. The new bone formation was found both in HA group and BMP-HA group more obviously than in Ti group. Under microscopy, it was noted that this new gradient HA-coating was intact and no obvious biodegradation in most section, whereas a fibrous membrane was found in Ti group. The average rates of interface osteointergration in Ti group, HA group and BMP-HA group were 4.05%?7.66%, 71.04%?9.81% and 88.86%?6.56%, respectively, those of HA and BMP-HA group were significantly higher than that of Ti group (P
