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.

Objective To investigate the evaluation value of magnetic resonance spectroscopy (MRS) combined with S-100B protein in the severity and prognosis in patients with acute subdural hematoma ( ASDH).Methods Eighty cases of ASDH patients and 20 cases of healthy check-up were selected.MRS was used to test NAA/Cr, Cho/Cr, NAA/Cho, and Glx /Cr in thalamus and corpus callosum.The blood S-100B protein was detected in 72 h after injury.The relationships of those MRS detection indices with glasgow coma scale ( GCS) and glasgow prognostic score ( GOS) for 2 months after injury were analyzed .Results MRS detection in-dex and the S100B protein in ASDH were compared between each group relative to normal control group , all difference had statistical significance ( P <0.05).As aggravating the severity of traumatic brain injury , Cho/Cr, Glx/Cr ratio, and S-100B protein concentra-tion were elevated , and NAA/Cho and NAA/Cr were reduced .All differences were statistically significant among poor recovery , good recovery, and normal control groups ( P <0.05).For patients with traumatic brain injury, there were worse prognosis, the higher ra-tios of Cho/Cr and Glx/Cr, higher concentration of S-100B protein, and lower ratios of NAA/Cho and of NAA/Cr.GCS score and GOS scores were negatively correlated with Cho/Cr and Glx/Cr ratios of corpus callosum , and were positively correlated with NAA/Cho, NAA/Cr ratios of corpus callosum .S-100B protein was positively correlated with Cho/Cr and Glx/Cr, and was negatively correlated with NAA/Cho and NAA/Cr.MRS combined S-100B can improve the prognosis of patients with up to the accuracy of 81%.Conclu-sions MRS detection in the early stage after injury of ASDH patients has important value in assessment of the severity of the injury and its prognosis , the accuracy of assessment of prognosis is improved with a combination of MRS detection and blood S -100 B protein meas-urement.

To analyze the characteristic of urinary protein spectrum in patients with stage III diabetic nephropathy (DN) and its compliance with traditional Chinese medicine (TCM)symptom, for the sake of providing a basis for clarifying the rules of TCM syndrome differentiation in DN. Adopting the traditional epidemiological retrospective method, thirty-eight TCM syndromes and urinary protein with medium or low molecular weight, as well as urinary enzyme, including 24 h urinary protein (Upro), urinary albumin( UAlb), urinary retinal binding protein( URBP), urinary cystatin C (UCysC), urinary N-acetyl-beta-D-glucosaminidase (UNAG), were collected from 108 patients with stage III DN, and a multiple factor regression analysis between them was conducted. As the results, the levels of Upro, UAlb, URBP, UCysC, and UNAG were increased in 108 patients with stage III DN. Qi-Yin deficiency type was the major type. The level of UAlb in patients with Qi-Yin deficiency type was significantly higher than those without Qi-Yin deficiency type (P < 0.05). The elevation of Upro with the factors as swift digestion with rapid hungering, lassitude and lack of strength, weakness of waist and knees was complied, the elevation of UA1b with the factors as dry mouth with desire to drink, the elevation of URBP with the factors as numbness of extremities, shortness of breath, the elevation of UCysC with the factors as clear urine in large amounts, and the elevation of UNAG with the factors as frequent micturition, were complied respectively. In conclusion, for 108 stage III DN patients. The increase in urinary protein spectrum including UAlb, URBP, UCysC, and UNAG is the major characteristic. Shen and Pi are the major organs related to the appearance of urinary protein; Pi-Shen deficiency is the basic pathogenesis. The level of UAlb is taken as one of the objective syndrome factors for Qi-Yin deficiency type. The levels of UNAG and UCysC are possibly the objective syndrome factors for Shen-Qi deficiency type.

OBJECTIVETo summarize the therapeutic effect of multiple types of posterior interosseous artery flaps for repair of soft tissue defects in the upper extremities.

METHODSFrom March 2003 to June 2010, 42 cases with soft tissue defects in the upper limbs resulting from burn and traumatic injuries were treated using multiple types of posterior interosseous artery flaps, including retrograde flaps and composite flaps, antegrade flaps ,and free flaps. Flap size ranged from 2.5 cm x 2.0 cm-14.0 cm x 9.0 cm. The defects in the donor sites were closed directly or covered by skin graft.

RESULTSThe conventional retrograde posterior interosseous artery flaps were used in 11 cases, the modified retrograde posterior interosseous artery flaps were used in 13 cases, the retrograde posterior interosseous artery composite flaps incorporating partial extensors were used in 2 cases, the antegrade posterior interosseous artery flaps were used in 3 cases, the free posterior interosseous artery flaps were used in 7 cases, and the free perforator flap based on the radiodorsal septocutaneous perforator of the posterior interosseous artery were used in 6 cases. Partial necrosis happened in one case at the distal portion of the flap. Muscular branch of the posterior interosseous nerve was injured in one case with conventional reverse posterior interosseous artery flaps. All the other flaps survived uneventually with no complication. All wounds were primarily healed. 32 cases were followed up for 1 to 48 months with satisfactory aesthetic and functional results both in the donor sites and in the recipient areas. The color,texture and thickness of the flaps were satisfied as well.

CONCLUSIONSThe posterior interosseous artery flap has a constant vascular anatomy and a great flexibility, which is practical and suitable for repair of Soft tissue defect in the upper extremities arising from burn and traumatic injury.

The study of human new gene's function has become an increasingly active academic field basically relying on the gene knockout (KO) mouse. The construction of targeting vector economically and efficiently has turned into the key step to acquire a KO mouse because of the low efficiency of recombination with traditional constructed targeting vector. For study of the function of new gene-Resp18, we brought in a new DNA engineering platform-Red/ET recombination to construct Resp18 targeting vector. Red/ET recombineering differs from the conventional ways of vector construction (e.g., PCR, restriction enzyme digestion and ligation) and achieves genetic modification by acquisition, insertion, fusion or replacement of the target gene through small fragments mediated homologous recombination. Now Resp18 targeting vectors of three strategies were yielded successfully through two homologous recombination processes of retrieve and neo-targeting. Red/ET recombination has the advantage of getting longer homology regions without mutation, which makes it a new and reliable alternative to the construction of a targeting vector today.

AIMTo study the relationship of neurotoxicity of 6-hydroxydopamine (6-OHDA) and the function of glutamate transporter.

METHODSUsing in vivo microdialysis together with high performance liquid chromatography (HPLC) to detect the alteration of glutamate in the striatum and extracellular fluid of the PC12 cell. The rate of apoptosis and the activity of PC12 cells are read in a flow cytometer and a photometer for enzyme-labeled assays. The function of glutamate transporter is decided by detecting the ability of L-[3H]-glutamate uptake.

RESULTS6-OHDA was shown to induce apoptosis and decrease the activity of PC12 cells. Increased release of glutamate was also found in PC12 cells and the injured striatum of the PD rats. But glutamate uptake in PC12 cells and rat striatum synaptosomes are inhibited obviously.

CONCLUSIONThe neurotoxicity of 6-hydroxydopamine is associated with declined function of glutamate transporters, which may be one important pathogenesis mechanisms of Parkinson's disease.

OBJECTIVEThis study was to investigate an operation, in which removing breast cysts of foreign body resulted from augmentation with polyacrylamide hydrogel injection was performed simultaneously with silicone prosthesis implantation under SEPS endoscope in order to relieve tissue injury and increase the accuracy of clearance.

METHODSEight patients were included in this study. Preoperative type B ultrasound examination was performed to mark the mass. Through an axillary approach, the cysts of foreign body that were distributed in the subcutaneous tissue, breast or muscle were separated and ablated under SEPS endoscope. After removal of the foreign body, a silicone implant was located submuscularly for breast augmentation.

RESULTSThe operations were completed without hematoma and infection. Follow-up of the eight patients for 3 to 12 months showed that preoperative symptoms relating to the injected material, such as breast pain, lump and asymmetry, have no longer existed. The shapes of the breasts were satisfactory.

CONCLUSIONSWe believe that endoscope-assisted mammoplasty offers more satisfactory clinical results with less injury, less morbidity, less scars, more accuracy and greater patient acceptance.

OBJECTIVETo identify the predictors of the positive results of transrectal ultrasound (TRUS)-guided biopsy for prostate cancer.

METHODSWe performed univariate and multivariate logistic regression analyses on the relevant data on 385 male patients that underwent TRUS-guided biopsy for prostate cancer, including such potential predictors as age, body mass index (BMI), symptoms, results of digital rectal examination (DRE), tPSA, fPSA, free/total PSA ratio (f/tPSA), prostate volume (PV), and PSA density (PSAD) for identification of the risk factors related to the positive rate of biopsy. Then we constructed a scoring system as a tool for predicting prostate cancer in repeat biopsies and determined the sensitivity of the system by calculating the false positive rate using the receiver operating characteristic curve.

RESULTSAmong the 385 patients, 139 (36.1%) were diagnosed with prostate cancer. On multivariate analysis, age (P < 0.01), DRE (P < 0.01), tPSA (P < 0.01), fPSA (P < 0.01), f/tPSA (P < 0.01), PV (P < 0.01), and PSAD (P < 0.01) were all significant predictors of prostate cancer. Multivariate logistic regression analysis showed age, tPSA, f/tPSA, PV, and PSAD to be independent predictors, with ORs and 95% CIs of 1.07 (1.05-1.16), 1.05 (1.02-1.15), 0.97 (0.86-0.99), 0.98 (0.87-0.96), and 1.79 (1.48-2.06), respectively. Moreover, patients with the risk score of 3-5 had a significantly higher rate of prostate cancer than those with 0-2 (64% vs 11%, P < 0.001).

CONCLUSIONThe scoring system on the key predictors of prostate cancer can help urologists to identify the men in need of prostatic biopsy.

OBJECTIVETo observe the effects of Dureping Injection on the contents of matrix metalloproteinase-9 (MMP-9) and tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) in the lung tissue of mice with pneumonia of influenza virus infection.

METHODSSixty-six ICR mice were randomly divided into the normal group, the model group, the low, middle, and high dose Dureping Injection groups (0.435, 0.870, and 1.740 mg/d, respectively), and the positive control group (Ribavirin, 2.500 mg/d), 11 in each. The pneumonia of mice with influenza virus infection model was established using influenza virus strain FM1. Mice were intraperitoneally injected with 0. 3 mL FM1 starting from the infection day, once daily. Five days later mice were killed to calculate the lung index. The pathomorphological changes of the lung tissue were observed using routine HE stained sections. The contents of MMP-9 and TIMP-1 in the homogenate of the lung tissue were detected by ELISA double antibody sandwich method.

RESULTSCompared with the normal group, obvious inflammation occurred in the lung tissue of mice in the model group. The lung index, the content of MMP-9, and the value of MMP-9/TIMP-1 increased significantly in the model group (P < 0.01) , while the content of TIMP-1 was not significantly different (P > 0.05). Compared with the model group, the content of MMP-9 in the low and middle dose Dureping Injection groups, and the positive control group was significantly lowered (P < 0.01). The content of TIMP-1 in the low, middle, and high dose Dureping Injection groups, as well as the positive control group significantly increased (P < 0.01) and the value of MMP-9/TIMP-1 decreased (P < 0.01).

CONCLUSIONDureping Injection could alleviate the inflammatory injury of the lung tissue through decreasing the content of MMP-9, elevating the content of TIMP-1 in the lung tissue, and regulating the value of MMP-9/TIMP-1 of mice with pneumonia of influenza virus infection, thus alleviating the inflammatory injury of the lung tissue.
