BACKGROUND: BK viral infection after renal transplantation influences the prognosis of BK virus-associated nephropathy in renal transplant recipients. The disease has been widely studied in foreign countries.OBJECTIVE: This study was designed to sum up the diagnosis and treatment of BK virus-associated nephropathy after renal transplantation.RETRIVAL STRATEGY: Using the terms "renal transplantation; BK virus" in the English language, manuscripts responsible for BK virus-associated nephropathy after renal transplantation that were published from January 2000 to January 2007 were retrieved from the PubMed database. A total of 206 manuscripts were obtained and primarily screened. Inclusion criteria: studies addressing BK virus-associated nephropathy after renal transplantation. Exclusion criteria: repetitive studies.LITERATURE EVALUATION: The included manuscripts were primarily from PubMed database. Manuscripts were primarily original and review studies.DATA SYNTHESIS: BK virus can be found in the urine of 3%-40% of adult renal transplant recipients. BK virus reactivation rate is very high, but the histological manifestations of BK virus associated nephropathy are found only in a small number of renal transplant recipients. The prognosis of BK virus associated nephropathy is very poor. BK virus associated nephropathy develops into renal failure, leading to transplant loss, in 30%-50% patients. BK virus-caused renal transplant disease must be diagnosed according to histological manifestations. Viral infection should be primarily confirmed, but serological measurements have no predominant effects. Electron microscopy should be involved in the assessment of renal graft biopsy, especially when renal failure factors are unknown, as through the use of electron microscope, viral particles in the nucleus, cytoplasm and outside of the cells could be detectable. Viral antigen in the urine sample of patients with BK viruria can be detected by nucleic acid hybridization method, immunofluorescence, and ELISA. Cidofovir is an effective medicine for treatment of BK virus-associated nephropathy, but its potential nephrotoxicity, proper dose, pharmacokinetics, safety, tolerance, anti-BK viral activities have not been confirmed. So fresher study should be required for aforementioned uncertainties.CONCLUSION: BK virus-associated nephropathy has poor prognosis and should be diagnosed according to histological examinations. BK virus-associated nephropathy has been treated primarily by symptomatic supportive treatment and reducing the dose of immunosuppressive agents.

In recent years, many versions of international standard terminologies on TCM have been established and enacted by different authoritative organizations worldwide. However, infantile tuina acupoints have never been included in them. The article illustrated the necessity of including infantile tuina acupoints in the international standard terminologies on TCM from the aspects of history, present state and specificity of these points. It also pointed out some problems of infantile tuina acupoints, such as different records of acupoints numbers, applications in the clinic and strategies applied in their English translation, and suggestions were provided accordingly, hoping that the infantile tuina acupoints can be included in the further revised versions of international standard terminologies on TCM.

Thirty-six cases of depression were mainlytreated by needling Shenmen ( HT 7), Sanyinjiao ( SP 6) and Zusanli (ST 36). In the case of liver-qi atagnation, Taichong ( LR 3) and Hegu ( LI 4) were added; in the case of phlegm-dampness accumulation, Fenglong ( ST 40) and Yinlingquan ( SP 9 ) were added; in the case of deficiency of both heart and spleen, Xinshu (BL 15) and Pishu (BL 20) were added. Fifteen cases were cured, 7 cases markedly improved, 8 cases improved and 6 cases failed.

In recent years,it has been reported that the osteopontin attracts great attention for its roles in tumor growth and metastasis.In many tumors,osteopontin plays an important role in promoting tumor growth,metastasis and enhancing adhesion and migration abilities.In particular,in hepatocellular carcinoma,osteopontin has very satisfactory sensitivity and specificity in early diagnosis and is relatively effective on prognosis prediction.Suppression osteopontin expression will inhibit liver cancer growth and metastasis,indicating that the osteopontin stays a new target for liver cancer treatment and possesses intangible clinical potential.

Objective: To detect the methylation status of DLEC1 promoter in the tissue and serum of colorectal cancer (CRC) patients and to evaluate its clinical relevance. Methods: Genomic DNA was extracted from the tissues (cancer tissue and. corresponding adjacent normal tissue) and sera of 71 CRC patients; serum genomic DNA was also obtained from 20 patients with benign gastrointestinal diseases and 20 healthy donors. Promoter methylation status of DLEC1 gene was detected by methylation-specific polymerase chain reaction (MSP). Results: The incidence of aberrant methylation of DLEC1 promoter was 45.1% (32/71) in CRC tissues, which was significantly higher than that in the adjacent normal tissues (7.1%, 4/56) (P< 0.001). The hypermethylation status of DLEC1 was not correlated with the clinicopathological features and CEA/CA19-9 levels of CRC patients. Moreover, DLEC1 promoter methylation was also found in 28 of 71 (39. 4%) CRC serum samples and only 1 (2.5%) of the other 40 cancer-free serum samples (P<0.001); the methylation was in accordance with that in the tumor tissues. Conclusion: Hypermethylation of DLEC1 promoter is frequently seen in CRC patients, suggesting it might be a promising biomarker for the early diagnosis of CRC.

Objective: To explore the urgent management strategy for quadriplegia following China Wenchuan earthquake under filed condition. Methods: The 57-year-old male patient was sent to the earthquake relief team of Changzheng Hospital, Second Military Medical University. He was hit by heavy object during the Sichuan earthquake 6 days ago. Physical examination revealed cervical spinal cord injury accompanied by incomplete paralysis. The patient underwent cervical 3-7 laminectomy under general anesthesia. Results: After surgery the muscle strength of lower limbs recovered to grade four from grade one; the muscle strength of upper limbs recovered to grade five from grade three. Sensory loss was found below the nipple level and totally recovered after operation. Conclusion: Early surgery for quadriplegia following earthquake trauma can timely relieve compression to the spinal cord and therefore improve prognosis of patients. Under field condition where facilities are not readily available, decompression of spinal cord can be achieved by laminectomy via posterior approach. The key to successful operation is correct diagnosis and skillful manipulation.

Objective To explore the neuroprotective effect of ginsenoside Rg1 against PC12 cell apoptosis inducedby 1-methyl-4- phenylpyridinum (MPP+). Methods MPP+-induced apoptosis in PC12 cells, with the characteristics of dopaminergic neuron, were taken as the model of Parkinson disease in vitro. The cells were divided into control group, MPP+ group and 3 ginsenoside Rg1 pretreatment groups (concentrations 10, 20, and 50 μmol/L). MTT assay was used for detecting the cell viability, FCM for apoptosis ratio, TUNEL enzyme labelling for DNA fragment of the cell nuclear, and Western blotting analysis for cytochrome C protein. Results Ginsenoside Rg1 (10, 20, and 50 μmol/L) showed protective effect against MPP+-induced PC12 cells injury. Compared with MPP+-treated cells([52±4. 7]%), pretreatment with 10, 20, and 50 |imol/ L ginsenoside Rg1 increased the cell viability to (64 ± 3. 4) %, (72 ± 5. 2) % and (83±6.2)%, respectively (P<0. 05 or P< 0. 01). FCM analysis indicated that apoptosis rates decreased by ginsenoside Rg1 pretreatment, with the apoptosis rates in the control, MPP+ and 3 ginsenoside Rg1 groups (10, 20, 50 μmol/L) being 1. 8%, 44. 5%, 32. 9%, 21. 1% and 14. 2%, respectively. We also found that ginsenoside Rg1 pretreatment greatly decreased DNA fragment of PC12 cells. Western blotting analysis indicated that the cytochrome C was depressed by the ginsenoside Rg1 pretreatment. Conclusion Ginsenoside Rg1 can protect PC12 cells against MPP+-induced apoptosis in a concentration-dependent manner, which may be closely related to down-regulation of cytochrome C over-expression in the mitochondria.

Objective To explore the neuroprotective effect of ginsenoside Rg1 against PC12 cell apoptosis induced by 1-methyl-4-phenylpyridinum (MPP++). Methods MPP++-induced apoptosis in PC12 cells, with the characteristics of dopaminergic neuron, were taken as the model of Parkinson disease in vitro. The cells were divided into control group, MPP++ group and 3 ginsenoside Rg1 pretreatment groups (concentrations 10, 20, and 50 μmol/L). MTT assay was used for detecting the cell viability, FCM for apoptosis ratio, TUNEL enzyme labelling for DNA fragment of the cell nuclear, and Western blotting analysis for cytochrome C protein. Results Ginsenoside Rg1 (10, 20, and 50 μmol/L) showed protective effect against MPP++-induced PC12 cells injury. Compared with MPP++-treated cells([52±4.7]%), pretreatment with 10, 20, and 50 μmol/ L ginsenoside Rg1 increased the cell viability to (64 ± 3. 4) %, (72 ± 5.2) % and (83±6.2)%, respectively (P<0.05 or P< 0.01). FCM analysis indicated that apoptosis rates decreased by ginsenoside Rg1 pretreatment, with the apoptosis rates in the control, MPP++ and 3 ginsenoside Rg1 groups (10, 20, 50 μmol/L) being 1.8%, 44.5%, 32.9%, 21.1% and 14.2%, respectively. We also found that ginsenoside Rg1 pretreatment greatly decreased DNA fragment of PC12 cells. Western blotting analysis indicated that the cytochrome C was depressed by the ginsenoside Rg1 pretreatment. Conclusion Ginsenoside Rg1 can protect PC12 cells against MPP++-induced apoptosis in a concentration-dependent manner, which may be closely related to down- regulation of cytochrome C over-expression in the mitochondria.
