Objective To report a Chinese boy suffering from nephrotic syndrome associated with Schimke immuno-osseous dysplasia (SIOD). Methods The clnical data and pathological changes of renal biopsy were analyzed and associated literatures were reviewed. The clinicopathological features and diagnosis of SIOD were discussed. Results The first symptom of the patient was recurrent infections. Growth retardation, spondyloepiphyseal dysplasia accompanied by nephrotic syndrome and defective cellular immunity were seen as clinical features in this patient. Renal pathology showed focal segmental glomerulosclerosis. Conclusion Combining the clinical manifestation with renal pathology, the case is diagnosed as Schimke immuno-osseous dysplasia.

Objective To investigate the specific immune responses induced by DNA vaccine com-bined with recombinant adenovirus carrying major outer membrane protein ( MOMP) gene of Chlamydia trachom-atis (Ct) serovar E.Methods Recombinant eukaryotic expression plasmid pVAX 1-MOMP and recombinant adenovirus Ad-MOMP were constructed and purified .Four immunization strategies were designed including DNA immunization (DNA group), recombinant adenovirus immunization (Ad group), DNA prime-recombinant ade-novirus boost regimen ( DNA/Ad group ) and recombinant adenovirus prime-DNA boost regimen ( Ad/DNA group) .Two weeks after the final immunization , vaginal wash specimens , blood samples and spleens were col-lected from all mice for the evaluation of humoral and cellular immune responses .Results Th1 responses and mucosal responses were not found in DNA group .Ad group induced both Th 1 responses and local mucosal re-sponses , and its IgG and IgA levels were significantly higher than those in DNA group .DNA/Ad group and Ad/DNA group induced stronger Th 1 responses and humoral responses than DNA and Ad group .Serum antibodies and mucosal antibodies in DNA/Ad group were higher than those in Ad/DNA group, but Th1 responses in DNA/Ad group were impaired than those in Ad/DNA group.Conclusion The recombinant adenovirus could induce Th1 responses and genital mucosal responses .Combined immunization of DNA/Ad or Ad/DNA showed enhanced specific immune responses in comparison with the single immunization with DNA or Ad .The differ-ences between the two combination methods were that DNA /Ad group stimulated higher levels of specific anti-body responses , while Ad/DNA group produced stronger Th 1 responses .The study provided a reference for the enhancement and development of vaccines against Chlamydia trachomatis in further studies .

AIM: To investigate the role of CD134 (OX40) and NF-?B in the pathogenesis of lupus nephritis (LN). METHODS: Renal in situ CD134 and NF-?B expression were examined in 40 biopsy specimens from LN patients by immunohistochemistry and microwave-based immunohistochemistry, respectively. The relationship between expression of CD134 and NF-?B was analyzed. RESULTS: The expression of glomerular and tubular CD134 and NF-?B in LN were higher than that in normal control, especially in class Ⅳ LN, where there was intense staining of endothelial cell, distal tubules, and interstitial mononuclear cell. The CD134 expression of glomerular and tubular was closely related to NF-?B expression, respectively ( r=0.5542,P

AIM: To investigate the effect of retinoic acid on proliferation of renal interstitial myofibroblasts in a rat model of the left unilateral ureteal obstruction (UUO). METHODS: UUO model was established by unilateral ligation of ureter in 36 SD rats. Rats were divided into 2 groups: Retinoic acid-treated group and control group, each with 18 rats. UUO rats were treated with either daily subcutaneous injection of 10 mg/kg body weight of all trans-retinoic acid or vehicle alone two days before the operation until being sacrificed. Groups of 6 rats were killed on day 3, 7 and 12 after ligation of the left ureter. The percentage of renal tubular lesion, interstitial fibrosis score, the number of interstitial myofibroblasts, the number of proliferating myofibroblasts and the expression of TGF?-1 mRNA were determined. RESULTS: There were significant accumulation and local proliferation of myofibroblasts in the interstitium of the UUO rats. On day 7 of the UUO model, the percentage of tubular lesions and interstitial fibrosis score were significantly lower in the retinoic acid-treated group than those in control group [(15.9?2.0)% vs (27.3?2.2)% and (0.47?0.12) vs (1.65?0.18), P

Objective To investigate the off-label use status in obstetrics ward so as to provide references for carrying out obstetrics pharmaceutical care and promoting safe medication use in pregnant and parturient women. Methods The prescriptions for pregnant and parturient women from January to June, 2015 in obstetrics ward were investigated. According to drug instructions, the off-label drug use of prescriptions of all selected patients was analyzed in the following aspects:the category of off-label drug use, and drugs use information. In addition, a logistic regression was conducted that modeled the odds of receiving an off-label prescription as a function of the following possible risk factors:pregnant, parturient women and the rank of doctors. The clinical results including the unreasonable drug application, abortion rate and birth defect were compared between the off-label drug use and on-label drug use groups. Results Total of 384 patients were selected, and 5330 prescriptions involving 50 drugs were analyzed. The rate of off-label drug use was 68. 5%, 27. 7% and 24. 0% in patients, prescriptions and drug categories, respectively. The main categories of off-label drug use were super solvent use ( 76. 6%) and indication (14. 3%). The top 3 drugs of off-label use were those for urinary and reproductive (56. 2%), alimentary tract (46. 9%) and traditional Chinese medicine (43. 4%). In addition, there was no significant correlation between the risk of off-label drug use and maternal status and the level of doctors. And no significant difference between the two groups in the unreasonable drug application, abortion rate and birth defect was detected. Conclusion The off-label drug use in obstetrics ward is common in this hospital and most of them are supported by clinical evidence. Due to the lack of more authoritative evidence-based medication, the doctors are suggested to use the drug according to provisions of the drug instructions. When off-label drug use is really needed, it should be based on the surpport of evidence basde medicine,so as to ensure the drug safety for pregnant and parturient women and avoid professional risks.

Objective To investigate the role of Notch signaling in the progression of peritoneal fibrosis in a rat model induced by high glucose dialysate. Methods Male Sprague Dawley rats were subjected to daily peritoneal dialysis (PD) with a lactate-buffered solution containing 4.25% glucose. They were sacrificed at 2 and 4 weeks after PD. The parietal thickness was measured with Masson staining. The expression of TGF-β1, E-cadherin, α-SMA and collagen Ⅰ was examined by immunoblotting. The expression of Notch ligand Jagged-1 and the negative Notch signaling regulato--Numb was analyzed by both immunoblotting and RT-PCR. The expression of a Notch nuclear target gene Hcs-1 was examined by RT-PCR. Results Both HE and Masson trichrome staining revealed an increase in peritoneal thickness with a loss of mesothelial cells and a rich of collagen matrix deposition in the submesothelial zone was evident at 4 weeks after PD. Meanwhile, compared to healthy rats, the expression of TGF-β1, ct-SMA and collagen Ⅰ was significantly increased, but the expression of E-cadherin was decreased in peritoneum after PD treatment. It was difficult to detect the Jagged-1 and Hes-1 expression in normal peritoneum, but their expression was graduaUy increased after PD. In contrast, the expression level of Numb, a negative regulator of Notch signaling, was dramatically decreased after PD. Conclusions Notch signaling is activated during the process of PD-induced peritoneal fibrosis and the activation of Notch signaling is associated with the loss of negative regulation of Notch signaling via decreased expression of Numb. Inhibition of Notch signaling via overexpression of its negative regulators such as Numb may be a novel therapeutic approach for peritoneal fibrosis in PD patients.

Objective To improve clinicians’ understanding of post transplant lymphoproliferative disorder (PTLD) after renal transplantation,a rare case of this disease was reported and literature was reviewed.Method The clinical data and pathological changes of the allograft,immunohistochenmistry (IHC) and in situ hybridization (ISH) were analyzed.In addition,the relevant literature was reviewed.The clinicopathological features and differential diagnoses of PTLD were discussed.Result A renal mass (5.6 cm × 5.4 cm),which was suggestive of primary renal malignancy,had been detected on the patient after received renal transplantation for a year and a half.Grossly,the mass was 7cm in diameter,with fleshy texture.Microscopically,the renal parenchyma was destructed and infiltrated with massive inflammatory cells,mostly lymphoid cells and occasionally Reed-Steruberg-like cells.IHC showed CD20 and CD79a were predominantly expressed in lymphoid cells.ISH showed diffused Epstein-Barr virus encoded RNAs (EBERs) positivity.The above findings were consistent with PTLD,polymorphic B cell hyperplasia (polymorphic PTLD),with concurrent EpsteinBarr virus infection.Conclusion Lymphoid infiltration in a renal allograft needs to be differentiated from T-cell rejection,viral infection,nephropyelitis,as well as PTLD.Early detection and proper management of PTLD may help improve the graft survival rate.

Objective:To analyze the hemostatic drugs use for orchidopexy in children during the perioperative period to promote the rational use of hemostatic drugs for orchidopexy in children. Methods:The perioperative prophylactic use of hemostatic drugs for orchi-dopexy in 138 children from June 2015 to December 2016 was retrospectively analyzed. The difference of clinical data and outcome indica-tors were compared between hemostatic drugs group(drug group) and without hemostatic drugs group (control group),and the rational use of hemostatic drugs in the drug group was analyzed. Results:The operation time,amount of bleeding and the length of hospital stay showed no statistical differences between the groups during the perioperative period in our hospital. There were 44.9% of children under-going orchidopexy treated with hemostatic drugs,and the unreasonable rate was 51.6% in the drug group. Among them,35.5% of chil-dren were with too long medication time,11.3% of children were with unreasonable initial treatment time, and 4.8% of children were with single overdose. Conclusion:The perioperative hemostatic drugs use for orchidopexy in children still has several problems, inclu-ding excessive medication duration,inappropriate administration time and single overdose etc,and clinicians should pay attention to above situations.

Objective To investigate the value of depth of invasion(DOI)and pattern of inva-sion(POI)in predicting recurrence and evaluating prognosis of early oral squamous cell carcinoma(OSCC).Methods Data of 109 patients with primary OSCC were retrospectively collected.The chi-square test was used to compare categorical variables of clinical data.Univariate and multivariate Logistic regression analyses were used to analyze the correlation between clinical data and tumor re-currence.Cox regression analysis was used to analyze the correlation between clinical data and overall survival of patients.Results Univariate analysis showed that POI,DOI and pathological grade were correlated with recurrence and poor prognosis of early OSCC.Multivariate Logistic regression analysis indicated that DOI was an influencing factor for OSCC recurrence(OR=4.515,95％CI,1.283 to 15.894,P＜0.05)and prognosis(HR=2.993,95％CI,1.225 to 7.317,P＜0.05).There was a high correlation between POI and DOI of OSCC.Conclusion DOI ≥5 mm is considered as a rele-vant factor for recurrence and poor prognosis of early OSCC.
