The research progress of the application of magnesium aluminum silicate in pharmaceutics was reviewed in this paper. We introduced the physiochemical properties and safety profile evaluations of magnesium aluminum silicate firstly. Then the research progress of the application of magnesium aluminum silicate was reviewed from the following five aspects: firstly, improving the fluidity of powder, increasing the hardness of tablets as well as preventingpowder from moisture caking; secondly, powdering oil-like drugs; thirdly, grinding poorly water-soluble crystalline drugs with magnesium aluminum silicate to form amorphous products, which can improve the dissolution rate of the drugs. In addition, the paper also reviewed the applications of magnesium aluminum silicate in solid dispersions, designing of sustained release formulations and so on.

·Hemophilia is a rare disorder that occasionally has visual symptoms after diagnosis. The authors present a case in which visual symptoms led to the initial diagnosis, a 22-year-old man who represented with spontaneous fundal haemorrhage. There is no history of bleeding and trauma. The fundal haemorrhage was absorbed significantly without any treatment after 3 months follow-up. Hemophilia A was found to be the causative disorder in this previously healthy man. The authors present a rare case in which unilateral visual complaints led to the diagnosis of hemophilia A. Thus, though uncommon, hemophilia should be considered in the differential diagnosis of otherwise unexplained fundal haemorrhages.

Objective To study the regulation of microRNA 199a (miR-199a) on adhesion,migration and invasion ability of human eutopic endometrial stromal cells (ESC) from patients with endometriosis.Methods ESC were transfected with miR-199a mimics or negative control (NC) RNA by lipofectamine 2000.The adhesion,migration and invasion ability of ESC were detected by cell adhesion assay,scratch assay,cell migration assay and matrigel invasion assay,respectively.Luciferase reporter assay was used to evaluate whether IKKβ was the target gene of miR-199a.The expression of ikappa B kinase beta (IKKβ),inhibitory kappa B alpha (IκB-α),phospho-IκB-α (p-IκB-α) and nuclear factor-kappa B (NF κB) protein were measured by western blot.Results ( 1 ) Adhesion potential:the adhesion inhibitory rates were ( 14 ± 4 )％ in miR-199a group and 0 in control group,which showed significant difference (P＜0.01 ).(2) Migration and invasion:in the scratch assay,ESC transfected with miR-199a exhibited a lower scratch closure rate than that of controls.In migration and invasion assays,the migration and invasion ability of miR-199a group were significantly decreased compared with those of NC group [ 130 ± 31 vs.247±36 (P＜0.01); 63 ± 15 vs.133 ± 17 (P＜0.01),respectively].(3) The luciferase activity of miR-199a group was significantly lowered than that of control group [ 0.160 ± 0.006 vs.0.383 ± 0.083 ( P ＜0.01 ) ].The protein levels of IKKβ,p-IκB-α,IκB-α and NF-κB of 0.350 ±0.195,0.443 ±0.076,1.970 ±0.486 and 0.454 ± 0.147 in miR-199a group were significantly different compared with the NC group in which the protein levels were set at 1.000 ( P ＜ 0.01 ).Conclusions miR-199a can inhibit the adhesion,migration and invasion of the ESC.IKKβ is the target gene of miR-199a in ESC.One of the mechanisms of the inhibition effect is probably that miR-199a inhibits the activation of NF-κB signaling pathway by targeting IKKβ gene.

Objective To investigate the diagnosis and treatment of primary hyperparathyroidism (PHPT) with urolithiasis.Methods The clinical data of 9 PHPT patients who were evaluated with simple metabolic evaluation in 881 urolithiasis from 2000 to 2005 were summarized and the references were reviewed.Results The level of serum calcium was (2.96±0.48)mmol/L before operation, (1.94±0.42) mmol/L after operation.The level of parathyroid hormone(PTH) was(1133.53±788.21)pmol/L before op-eration,(74.52±49.17)pmol/L after operation.The level of serum calcium and PTH changed significantly after the parathyroidectomy (P<0.01).Follow-up for 14 months to 6 years.the ureteral stones fragments with lithotripsy were clear after 3 months and followed without recurrence,although the renal stones without lithotripsy were followed with no significant change.Conclusions Increase of serum calcium or increase of PTH above double with normal serum calcium may be helpful for diagnosis of PHPT with urolithiasis.Ureteral stone with PHPT should be treated together.Renal stone with PHPT may be followed up after the parathv-roidectomy,and be treated until the complications were occurred.It suggests that the maidend diagnosed pa-tient with urolithiasis should be added with simple metabolic evaluation,including serum calcium, phospho-nium and PTH.

OBJECTIVETo analyze the reasons why anterior decompression and titanium mesh fusion for cervical spondylosis always show poor therapeutic effects, and to investigate the clinical effects of anterior revision surgery in these patients.

METHODSFrom January 2004 to December 2011, 16 patients underwent anterior decompression and titanium mesh fusion for cervical myelopathy were treated with anterior revision surgery. There were 7 males and 9 females with an average age of 61 years old (ranged from 46 to 75 years), including 11 cases with cervical spondylotic myelopathy, 2 cases with nerve root cervical spondylosis and 3 cases with mixed type cervical spondylosis. Average duration from the first operation to reoperation was 7 years(ranged from 4 to 12 years). In the first operation, titanium mesh segment located in C3-C5 (2 cases), C4-C6 (8 cases), C4-C7 (2 cases), C5-C7 (4 cases), and one of them, titanium mesh implantation in C4 and C5,6 intervertebral disk removal and cage fusion. After the first operation, symptom of 13 patients recurred after improvement or disappearance, 2 patients did not show obvious improvement, and 1 patient aggravated. Cervical spine radiography, CT scan and MRI were performed in all patients before re-operation. There were 12 patients with compression of the spinal cord or nerve root caused by degenerative changes in adjacent segments of fusion segments, 4 cases in upper segments, and 8 cases in lower segments; 3 patients with compression of the spinal cord or nerve root caused by vertebral posterior osteophyte of decompressed segments; 1 patient with compression of the spinal cord caused by incomplete anterior decompression. JOA, NDI and Odom classification were used to assess the clinical effects.

RESULTSAll anterior revision surgery were successful with a mean time of 110 min (80 to 150 min) and mean bleeding of 160 ml (30 to 200 ml). There was 30 ml clear drainage fluid in 1 patient suspected of cerebrospinal fluid leakage. But the 2nd day after operation, the tube was removed and the drainage opening was sutured, and the suture incision healed in grade A after 10 days. Other patients had no complications such as dysdipsia, hoarseness, and laryngeal edema, etc. All patients were followed up for 12 to 28 months with an average of 16 months. Two months after operation and at last follow-up, JOA scores and ODI index had obviously improved than preoperation (P < 0.01), and there was significant difference between postoperative 2 months and last follow-up (P < 0.01). At the final follow-up, improvement rate of JOA was (72.9 +/- 0.2)%. According to the standard of Odom, 12 cases got excellent results, 3 good, 1 fair.

CONCLUSIONAfter surgery of cervical decompression and bone graft fusion with titanium mesh, the patients need re-operation because of incomplete decompression, degenerative changes in adjacent segments or newly formed compression factors, and complications caused by implants. Anterior revision surgery can obtain good clinical effects.

Total 149 strains of endophytic bacteria were isolated from different healthy organisms of Glycyrrhiza inflata Bat. from Xinjiang. The fermented liquids of these strains were screened by TLC and analysed by HPLC, and the glycyrrhizinic acid monoammonium salt was taken as standard control at the same time. Only one endophtytic bacterial stain of Bacillus subtilis could produce Glycyrrhizinic acid monoammonium salt analogue.

Objective To investigate the expression of slit diaphragm proteins of glomerular podocyte,such as NEPH1 and Nephrin in type Ⅴ lupus nephritis (V-LN). Methods Twenty-five patients with V-LN and 18 patients with idiopathic membranous nephritis (IMN) were enrolled into the study, and 5 normal renal samples were the normal control group. Twenty-four hours urine protein excretion, serum albumin, creatinine, triglyceride, total cholesterol, serum C3, C4, urine C3 and NAG were tested respectively.Glomerular lesions were measured by light microscopy. The expressions of NEPH1 and Nephrin were determined by indirect immunofluorescent staining. The statistical treatment was used t-test. Results Compared to the IMN group, the 24 hours urine protein excretion and the concentrations of serum albumin, creatinine, urine C3 were not significantly different while the triglyceride, total cholestorel, serum C3, C4 were significantly decrease in the V-LN group (P<0.05). Urine NAG was increased in the V-LN group (P<0.01). By indirect immuno-fluorescent histochemitry examination, the glomerular expressions of NEPH1 and Nephrin were significantly decreased in both V-LN and IMN. Compared with the IMN group, the decrease of NEPH1 and Nephrin expression was more remarkable in the V-LN group. Conclusion The expression changes of NEPH1 and Nephrin may play an important pathogenic role in proteinuria of Ⅴ lupus nephritis. Renal tubular epithelial cell damage may play a role in proteinuria of V-LN.

Its basic pathological lesions are characterized by necrotizing vasculitis. We present a case of propylthiouracil-induced APV, with regard to its pathogenesis, clinical manifestation, diagnosis, treatment, and outcomes for futher understanding this disease.

In clinic, some urinary protein makers can dynamically and noninvasively reflect the degree of renal tubular injury in patients with diabetic nephropathy (DN). These urinary biomarkers of tubular damage are broadly divided into two categories. One is newfound, including kidney injury molecule-1 (Kim-1), neutrophil getatinase-associated lipocalin (NGAL), liver-type fatty acid-binding protein (L-FABP) and cystatin C (CysC); the other one is classical, including beta2 microglobulin (beta2-MG), retinal binding protein (RBP) and N-acetyl-beta-D-glucosaminidase (NAG). It is reported that, the increases in urinary protein markers are not only closely related to the damage of tubular epithelial cells in DN patients, but also can be ameliorated by the treatment with Chinese herbal compound preparations or Chinese herbal medicine. Recently, although urinary proteomics are used in the protein separation and identification, the traditional associated detection of urinary protein markers is more practical in clinic. At present, it is possible that the associated detection of urinary biomarkers of glomerular and tubular damages may be a feasible measure to reveal the clinical significance of urinary protein markers in DN patients and the interventional effects of Chinese herbal medicine.
