OBJECTIVETo explore the effect of Jianpi Qinghua Recipe (JQR) on renal functions of adriamycin-induced focal segmental glomerular sclerosis (FSGS) rats from the angle of activating fibroblasts to myofibroblast (MyoF).

METHODSTotally 56 rats were randomly divided into the normal control group (n=8), the sham-operation group (n =8), and the model group (n=40). The FSGS rat model was induced by nephrectomy of left kidney plus intravenous injection of adriamycin. Successfully modeled rats were further divided into 5 groups, i.e., the model group, the JQR group, the JPR (Jianpi Recipe) group, the QHR (Qinghua Recipe) group, and the NDQ (Niaoduqing) group, 8 in each group. Corresponding drugs were administered to rats in all groups, 2 mL each time, for 56 days. The effect of JQR on serum creatinine (SCr), urea nitrogen, 24-h urinary protein excretion, a-smooth muscle actin (alpha-SMA) mRNA, collagen type III (Col III) mRNA, fibronectin (FN) mRNA, and collagen type IV (Col IV) mRNA were observed.

RESULTSJQR could significantly lower SCr, urea nitrogen, and 24-h urinary protein excretion levels (P < 0.01), and significantly decrease mRNA levels of alpha-SMA, Col III, FN, and Col IV (P < 0.01). It was advantageous over the NDQ group. Compared with JPR, the relative expression levels of Col III mRNA and FN mRNA of JQR and QHR were significantly lower (P < 0.01).

CONCLUSIONSJQR could improve the renal function and renal fibrosis in the adriamycin-induced nephropathic model rats. Its efficacy was superior to that of NDQ. Its mechanisms might be linked with inhibiting activation of fibroblasts.

Objective To study the ultrasonographic characteristics of Wilms′tumor (WT), aims at elevating the diagnostic level.Methods We retrospectively studied sonographic features in 30 cases of WT proved by operation and pathology.Results The tumors with heterogeneous pattern of solid and cystic tissue were shown in 22 cases.Seven cases demonstrate predominantly echogenic tumor. A huge cystic mass with numerous septas was shown in 1 case. The tumor extended into renal pelvis in 4, into renal vine in 1.The tumor metastasized to lymphnod in 1, to bilateral lungs in 1. Among 30 cases, the tumor was huge and grew beyond the renal profile in 26 cases, in 3 cases the tumors took up the renal sinus and made its structure turbulence, the renal shape was approximately normal.One case was extrarenal WT,the tumor located in retroperitonemu.Conclusions Sonographically, typical WT is a large heterogeneous mass within or without cystic areas, it also can be a pure cyst. It is easy to diagnose. When the tumor is limited to renal outline, it is easy to confusion with renal cancer. In addition, there are bilateral WT and extrarenal WT. The sonographic characteristics is similar among WT, clear cell sarcoma of kidney, malignant rhabdoid tumor and congenital mesoblastic nephroma. It is difficult to distinguish them from ultrasonography.

Objective To summarize the sonographic characteristics of Peutz-Jeghers syndrome in children and investigate the diagnostic value of ultrasound.Methods Retrospective analysis of sonographic characteristics of 19 cases with pathologically-confirmed Peutz-Jeghers syndrome were conducted.ResultsExcept for one child,other 18 patients all had more than one polyp with the maximum of sixteen.The polyp with the smallest size of 0.8 cm×0.5 cm×0.8 cm was found in left colic flexure,while the largest one was found in superior rectal with a measurement of 7.6 cm×2.7 cm×3.6 cm.The polyps showed radiatiform echotexture.And hypoechoic and hyperechoic components were present alternately.Blood flow was easily identified within these polyps by color Doppler sonography.Intussusceptions were observed in 11/19 patients.Among them,10 cases were located at small intestine.The sonographic finding was a concentric structure with a polyp at the top.Conclusions The sonographic appearence of Peutz-Jeghers syndrome is characteristic.Before surgery,ultrasonographic examination could achieve a accurate diagnosis for Peutz-Jeghers syndrome.

Objective To describe the sonographic appearance of mesenchymal hamartoma of the liver(MHL)and to analyze the diagnostic value of ultrasound.Methods Eleven surgically and pathologically confirmed cases of MHL from January 2005 to May 2011 in the Beijing Children′s Hospital were retrospectively reviewed.Results Ultrasound examinations showed 9 cystic hamartomas,including 7 multiseptate cystic and 2 monocystic lesions.Of the 7 multiseptate cystic hamartomas,4 had a honeycomb appearance and 3 had irregularly-distributed multiple cysts with varied septations.Of the 2 monocystic hamartomas,1 had a large cystic portion while the other was mainly solid with approximately 4% cystic portion of the tumor.Two cases in this group were solid,presenting with a well-defined homogenous mass.Conclusions Ultrasonography is an effective imaging modality for the diagnosis for MHL.A mixed or a mainly-cystic liver mass found in a child less than 2 years old should be suspicious for MHL.

Objective To establish the proper review rules for the microscopic screening of urine samples tested by automatic urinalysis work station.Methods A total of 3 154 random urine samples were enrolled to establish and validate review rules .All the samples were collected from the inpatients and outpatients of Shanghai First People′s Hospital from March to May 2013 and tested by urinalysis work station.Three thousands one hundred and fifty four urine samples were firstly tested by urinalysis work station,including both urine dry chemical analyzer and urine sediments analyzer .Then each urine sample was examined microscopically by two technicians-in-charge using double-blind method.The average results from the two technicians were used as review results .Compared with review results ,the review rules were set up.According to different test methods by automatic urinalysis work station , four microscopic review protocols were defined:(1)Protocol 1:based on chemistry results only ,microscopy review was performed when any of WBC,RBC,PRO and NIT was positive;(2)Protocol 2:based on urine sedimental analysis only ,microscopy review was performed when any of WBC ,RBC and CAST count was over upper limit of the reference range;(3)Protocol 3:if any of BLD ,RBC,LEU,WBC was different between two systems ,or quantitative results had two or more than two gradient differences ,microscopy review was performed;(4) Protoco1 4:if any of BLD, RBC,LEU ,WBC was different between two systems , or CAST was over upper limit of the reference range , or alarm appeared , microscopic review was performed .400 randomly selected urine samples were tested to validate the review rules .Omission diagnostic rate and review rate were used to evaluate the rules .Results According to the review rules,the positive samples rate was 43.47%(1 371/3 154) and the negative rate was 56.53%( 1 783/3 154 );Positive samples were composed of RBC ( 55.58%) , WBC ( 59.66%) and CAST(6.42%).The review rates of four protocols were 44.48%(1 403/3 154),45.69%(1 441/3 154), 26.09%(823/3 154),28.95%(913/3 154),respectively.The false negative rates (omission diagnostic rates)were 7.13%(225/3 154),4.53%(143/3 154),2.73%(86/3 154) and 1.02%(32/3 154), respectively .Protocol 4 was selected as an ideal plan.Additional 400 urine samples were tested using protocol 4 in order to confirm the review rule.The review rate, false negative rate were 26.25%(105/400), 0.75%( 3/400 ), respectively.After image review revised, the review rate was 14.50%(58/400).Conclusion This study formulates that the automatic urine analysis workstation review rules have clinical maneuverability and validity.

OBJECTIVETo study the anti-immune inflammation efficacy and toxicity of Tripterygium wilfordii decoction, in order to provide experimental basis for studies on its "efficacy-toxicity" correlation.

METHODThe delayed hypersensitivity model was established by dinitrofluorobenzene in mice. Different doses of T. wilfordii decoction was administered for 5 consecutive days. The ear swelling inhibition ratio and the toxic action were observed. After the final administration, the biochemical indexes of PGE2, TNF-α, IL-2, ALT, AST, PA, TBA, TBIL in serum were detected, and the visceral indexes of heart, liver, spleen and kidney were measured.

RESULTThe DNFB-induced ear swelling could be notably inhibited by multiple oral administration of T. wilfordii decoction, with the ED50 and its 95% confidence limit of 0.34 (0.21-0.42) g x kg(-1). The contents of PGE2, TNF-α, IL-2 in serum decreased in a dose-dependent manner. The activities of serum AST, ALT, TBA, TBIL and the PA content reduced.

CONCLUSIONT. wilfordii decoction shows a significant anti-immune inflammation efficacy within the dosage range between 0.59 and 2.34 g x kg(-1) in a dose-dependent manner. With a certain hepatotoxicity, high dose (2.34-4.68 g x kg(-1)) of T. wilfordii decoction can cause substantial liver injury, with a dose dependence in liver function index. Therefore, the efficacy and toxicity of T. wilfordii is dose dependent, which provides reference for preventing adverse drug reactions in clinic and developing early-warning schemes and ensure the clinical medication safety of T. wilfordii.
