Objective To study the renal damage of patients with juvenile primary Sjgren's syndrome (pSS)and its clinical manifestations,pathologic characteristics with biopsy,treatment and prognosis.Methods Ten patients with juvenile pSS complicated with renal impairments were retrospectively analyzed.Data of these 10 patients were compared with those without renal impairments.Results Ten patients complicated with renal impairments in 24 patients with juvenile pSS,9 of them presented with type I renal tubular acidosis(RTA), 5 with hypokalemia paralysis,3 with calcification of the renal tissue,3 with positive urine protein.1 with dia- betes insipidus.There was no significant difference between patients with renal impairments and those without. Three patients underwent kidney biopsy that showed chronic interstitial nephritis(CIN)with extensive lymp- hoplasmie cell infiltration.Two patients had glomerular lesions and one of them was diagnosed as pSS over- laped with systemic lupus erythematosus(SLE).Steroid and immunosuppressive agents had significantly alle- viated symptoms and the hypergammaglobulinemia was significantly improved.Conclusion Renal impairment may be the major complication in juvenile pSS.The major clinical manifestations are RTA and the glomeruli are involved occasionally.Treatment with steroid anti immunnsuppressive agents should be given to those who have evidence of systemic involvement.

OBJECTIVETo comparatively study the curative effects of combined massage-smouldering-washing therapy (MSW) and mini-invasive surgery in treating knee osteoarthritis (KOA) of mild-moderate degree so as to provide a suitable therapeutic protocol.

METHODSSixty patients with KOA were assigned to two groups. The treatment group was treated with MSW once a day for 10 days as one course, and 4 courses were applied totally with an interval of 3 days between courses. The control group was treated with mini-invasive surgery by arthroscopic mopping, followed with post-operational intra-articular cavity injection with sodium hyaluronate injection, 20 mg every week for 5 times continuously. The therapeutic effect and the changes in scores of clinical symptoms and signs before and after treatment in the two groups were observed and compared.

RESULTSOutcome of 3-month follow-up showed the effective rate was 90% in the treatment group and 93.33% in the control group; scores of clinical symptoms and signs effectively improved in both groups, but the improvement on the 4 items (joint pain, swelling, soreness of loin and knee, and cold aversion of knee) was superior in the treatment group, while that on the other 4 items (pain during squatting or half-squatting, up stairs or down stairs, joint stiffiness and joint kinetic capacity) was superior in the control group (P < 0.05).

CONCLUSIONBoth MSW and mini-invasive surgery have definite curative effect on KOA but with different particularities.

Powder X-ray diffraction (PXRD) technology combined with cluster analysis method was used to classify 75 batches of crystalline ceftriaxone sodium into subtypes, the crystalline characteristics of each subtype were measured with scanning electron microscope (SEM). By comparing some parameters of these subtypes correlated to crystallization process of ceftriaxone sodium, such as salification rate, water content in different subtypes, as well as by studying different lattice stabilities, different compatibilities with rubber closures during accelerated stability tests, the key point to improve the quality of domestic ceftriaxone sodium was disclosed. The results of this paper indicated that the fine structure of the products could be controlled well by improving the salification and crystallization process. As a result, the subtype II of ceftriaxone sodium with high stability can be produced.

OBJECTIVETo investigate results of total knee arthroplasty using the long-stem tibial component combined with metallic wedge of knee prosthesis for the treatment of proximal defects.

METHODSFrom January 2011 to May 2013, 10 patients (11 knees) were treated with total knee arthroplasties using the long-stem tibial component with metallic tibial wedge of knee prosthesis. All the patients were female and the average age was 67 years old (ranged, 60 to 77 years old). All the patients were osteoarthritis. All the patients were classified as T2A style. The patients were evaluated according to knee score system (KSS).

RESULTSAll the patients were followed up for 12 months on average (ranged 3 to 29 months). The clinical outcome was assessed using KSS score, including knee pain score, knee stability score, knee range of motion score and knee walking score, knee stairs score. There were significantly differences at 6 weeks, 3 months, 6 months and 12 months between pre-and postoperative KSS score.

CONCLUSIONThe mechanical stability of tibial fixation in primary TKA is significantly increased by using the long-stem tibial component with metallic wedge of knee prosthesis, even in the presence of poor proximal bone.

OBJECTIVETo explore the possible effect of transforming growth factor-beta(1) (TGF -beta(1)) on the development of renal fibrosis in human mesengial proliferative glomerulonephritis (MsPGN).

METHODSImmunohistochemistry method, sirius red staining polarization microscopy and the computer imaging analysis system were used to detect the expression of TGF-beta(1), the distribution of collagen I, collagen III and collagen IV.

RESULTIn MsPGN with renal fibrosis, collagen IV was increased markedly,and collagen I and collagen III appeared in the expanded mesengial matrix abnormally. Collagen III and collagen IV were increased markedly in tubulointerstitium. TGF-beta(1) expression was positively correlated with the expression of collagen I, collagen III and collagen IV in tubulointerstitium (r=0.82 0.92,P<0.01), and negatively correlated with I/III, I/IV and III/IV (r=-0.83,-0.92, P<0.001).

CONCLUSIONAbnormal increase of TGF-beta(1) may be one of the important factors associated with glomerular sclerosis and tubulointerstitial fibrosis through the increment and abnormal distribution of collagen I, collagen III and collagen IV.

Objective To evaluate the automatic synthesis of 18F-labeled cyclic RGD peptide c(RGDyK)and its biological distribution in the tumor-bearing mice. Methods N-succinimidyl-4-18 F-fluorobenzoate (18F-SFB) was automatically synthesized and then re-dissolved in acetonitrile (MeCN). The cyclic RGD peptide c(RGDyK) was mixed with an hydrous DMSO and N, N-diisopropyl ethylamine (DIPEA). 18F-FBRGD was obtained by the reaction of peptide solution with 18 F-SFB. The final product was purified by HPLC gradient separation system and solid-phase extraction method. The biodistribution study and competition test of N-4-18F- fluorobenzoyl-RGD (18F-FB-RGD) in the tumor-bearing mice was performed. Results The labeling yield of 18 F-FB-RGD was (33.6 ± 3.5)%. The synthesis time was 110 min. The radiochemical purity was more than 98%. The tumor uptake of 18F-FB-RGD was (3.43 ±0.15), (2.61 ±0.14), (2.11 ±0.13), and (1.79 ±0.18) %ID/g, respectively, at 30, 60, 90 and 120 min after injection. The ratio of tumor to muscle activity ranged from 4.26 ±0.69 to 5.80 ±0.78. The tumor uptake decreased dramatically after RGD blockage. The uptake was (0.46 ±0.21) %ID/g and (2.87 ±0.59) %ID/g in the blocked and unblocked mice, respectively, at 60 min after blockage. Conclusions 18 F-FB-RGD can be automatically synthesized and it may become a promising tumor imaging agent.

Objective To identify the differentially expressed gene profiles in myocardium of patients with heart failure using human whole genomic oligonucleotide microarray-assisted pathway analysis. Methods Phalanx whole genomic oligonucleotide microarrays were used to detect the gene expression profiles of myocardium in four patients died of heart failure and 4 brain died patients without heart diseases. The microarray findings were confirmed by real-time quantitative reverse transcriptase-polymerase chain reaction. The genes with a threshold of 1.2 times fold-change were selected and BioCarta Pathway and KEGG ( Kyoto Encyclopaedia of Genes and Genomes) pathway databases were used to identify functionally related gene pathways. Results A total of 2806 genes with differentially expression were detected between the failing and non-failing heart samples, expression changes of 399 genes were more than 2-folds. Eleven pathways were identified by BioCarta pathway database and sixteen athways were identified by KEGG PATHWAY Database. Conclusion Genomic microarray-assisted pathway analysis could help to identify gene expression profiles in failing heart.

OBJECTIVETo observe the dynamic expression of calcium-sensing receptor(CaSR) in myocardium of diabetic rats.

METHODSThirty male Wistar rats were randomly divided into 3 groups including control, diabetic-4 week and diabetic-8 week groups(n = 10). The type 2 diabetes mellitus models were established by intraperitoneal injection of streptozotocin (STZ, 30 mg/kg) after high-fat and high-sugar diet for one month. The cardiac morphology was observed by electron microscope. Western blot analyzed the expression of CaSR, phospholamban (PLN), a calcium handling regulator, and Ca+-ATPase(SERCA) in cardiac tissues.

RESULTSCompared with control group, the expressions of CaSR and SERCA were decreased, while the expression of PLN was significantly increased in a time-dependent manner in diabetic groups. Meanwhile diabetic rats displayed abnormal cardiac structure.

CONCLUSIONThese results indicate that the CaSR expression of myocardium is reduced in the progression of DCM, and its potential mechanism may be related to the imnaired intracellular calcium homeostasis.
