Objective To investigate mRNA expression levels of cathepsin B,cathepsin L and uPA in non-Hodgkin lymphoma (NHL) samples,and analyze the relationship between three genes and clinicopathological factors.Methods Real-time fluorescence quantitative RT-PCR was used to quantify the relative expression levels of cathepsin B,cathepsin L and uPA mRNA in 39 NHL patients without chemotherapy or radiotherapy and 15 patients with lymph node reactive hyperplasia.Relationship between their expression and clinico-pathological factors was analyzed.Results mRNA expression levels of cathepsin B,cathepsin L and uPA in NHL group were significantly higher than those in the control group (0.403 vs 0.128,0.209 vs 0.057,0.459 vs 0.031,all P ＜ 0.05).The mRNA expression levels of cathepsin B,cathepsin L and uPA were correlated with each other in NHL.The mRNA expression levels of cathepsin B,cathepsin L and uPA in advanced staged NHL were markedly higher than those in early staged NHL (0.453 vs 0.341,0.204 vs 0.085,0.372 vs 0.196,all P ＜ 0.05).mRNA levels of cathepsin B,cathepsin L and uPA were higher in NHL patients sensitive to chemotherapy than in those resistant to chemotherapy(0.401 vs 0.556,0.085 vs 0.205,0.316 vs 0.499,all P ＜ 0.05).Conclusions The high expression of cathepsin B,cathepsin L and uPA could be detected in NHL,and their expression has a close relationship with the biological behavior characters of NHL.The dynamic examination of cathepsin B,cathepsin L and uPA may be used as clinical auxiliary diagnosis and prognosis of NHL.

Objective To investigate whether efflux mechanism is involved in azole resistant Candida albicans strains isolated in China. Methods We compared rhodamine 6G uptake and glucose induced efflux between azole sensitive and azole resistant strains to elucidate resistance to azole due to efflux pump, then measured mRNA level of efflux gene cdr1 and cdr2 by reverse transcriptase polymerase chain reaction (RT PCR). Results Rhodamine 6G moved from extra into the intracellular compartment in both azole resistant and azole sensitive strains quickly when in glucose free incubation condition. However, efflux of rhodanmine 6G was enhanced significantly in azole resistant strains and decreased in azole sensitive strains while adding glucose in the media. The mRNA level of efflux gene cdr1 and cdr2 was higher in clinical azole resistant strains and fluconazole induced resistant strains than strains reverted from resistance to sensitivity. However, all such strains had higher efflux gene expression than azole sensitive strains. Conclusions Efflux mechanism is associated with the resistance to azole in Candida albicans strains isolated in China. Fluconazole can induce efflux pumps expression leading to resistance to azole but the resistance to azoles can be reversed after withdrawing fluconazole.

MicroRNA is a type of endogenous noncoding small molecular RNA with a length of 19-25 nucleotides. MicroRNAs are involved in almost all key biological processes, such as cell proliferation, differentiation, apoptosis, and hematopoiesis, via repres-sion of target gene expression. Acute lymphoblastic leukemia (ALL) is the most common type of pediatric cancer. It is a heterogeneous disease with different clinical signs, morphology, immunophenotype, and cytogenetics. Currently, several microRNAs have implicated aberrant expression in ALL and play an important role in cancer initiation and development. MicroRNA expression pattern is associated with clinical feature, prognosis, and treatment. Therefore, microRNAs could act as a novel marker to help scientists learn about the pathogenesis of ALL and to provide more effective treatment options.

Heart disease is the major disease that threaten human health. ECG is an important tool for the diagnosis of cardiac disease. As traditional ECG measurement devices have many disadvantages, a non-contact ECG measurement system was designed. With the non-contact electrode based on capacitive coupling, the signals were collected and then they were amplified and filtered. The conditioned analog signal was converted to digital data which was sent to the mobile terminal through bluetooth. Finally, the ECG data was analyzed to extract the key ECG parameters. The results showed that the precise ECG signals can be got with the non-contact electrode and the key ECG parameters can be acquired accurately.

Objective To construct radiation inducible-specific hytk gene therapy vector using radiation inducible gene Egr-1 promoter,and to determine its feasibility in bladder carcinoma gene therapy. Methods A radiation inducible-specific hygromycin phosphotransferase-thymidine kinase fusion gene(hytk)vector was constructed by subcloning hytk gene into pCIneo/Egr-1 vector, which was carrying Egr-1 promoter.Then the vector was transferred into bladder carcinoma cells lines EJ with FuGENE TM 6.Antitumor effects were observed after irradiation with 60 Co-rays as well as gancyclovir(GCV) treatment. Results The new cell line,EJ/Egr-1-hytk,incorporated and expressed the hytk gene,which was proved by RT-PCR and Western blotting.Egr-1 promoter actively drived hytk gene expression in the presence of ?-rays in the EJ cells, while lower hytk expression was detected without ?-rays.Antitumor effects were observed after ?-rays irradiation with 60 Co rays and GCV treatment. Conclusions Hytk-based vector harboring Egr-1 promoter is a novel ideal candidate vector for bladder carcinoma gene therapy.

Objective To evaluate the safety and efficacy of microsurgical resection of large acoustic neurinoma via the suboccipital retrosigmoid approach.Methods Forty-nine patients with large acoustic neurinoma(≥4 cm) underwent microsurgical resection through suboccipital retrosigmoid approach.The craniotomy was performed by way of an unilateral S-shaped suboccipital incision.With microsurgical techniques the outmost layer of the arachnoid membrane was preserved in order to avoid damaging to the surrounding vital structures.The tumor was resected intracapsularly from the superior pole and the internal auditory meatus was finally opened.The last pieces of tumor were removed by sharp dissection from the facial nerve bidirectionally,and were resected cautiously in a piecemeal fashion.Results Of the 49 patients,45 patients(92%) received a total resection of the tumors,and 4 patients(8%) subtotal resection.No patients died.The facial nerve was preserved anatomically in 42 patients(86%) and functionally in 36 patients(73%).The acoustic nerve was preserved anatomically in 7 patients(14%) and functionally in 3 patients(6%).One patient experienced a postoperative haematoma,and a re-operation was required.No recurrence was seen in 37 patients during a follow-up for 6 months ～ 5 years(mean,2.8 years).These patients had recovered for normal work and daily activities.Conclusions Microsurgical operation through suboccipital retrosigmoid approach is a favorable treatment for large acoustic neurinomas.The procedure can improve the rate of total resection,decrease the morbidity and mortality,and effectively protect the function of the acoustic and facial nerves.

Objective To explore the outcomes of endoscopic minimally invasive surgery as a new technique for the treatment of glossopharyngeal neuralgia.Methods From January 2000 to May 2008,16 cases of primary glossopharyngeal neuralgia were treated by endoscopic minimally invasive surgery through suboccipital retrosigmoid approach in our hospital.We made a 6-to 8-cm vertical incision within the inner hairline to drain the cerebrospinal fluid from the cerebellopotine angle cistern(CPA) so that to form an operational path.And then,the adherent arachnoid membrane was freed and the structure of the glossopharyngeal nerve and local arteries were detected.Results After the endoscopic surgery,pharyngeal pain disappeared in all of the 16 cases.Follow-up was available for 3 months to 8 years in the patients(1-3 years in 4 cases,and 3-8 years in 2 cases).Two patients had hoarse voice after the operation.No one had dysphagia or recurrence during the follow-up.Conclusion Endoscopic surgery through suboccipital retrosigmoid approach is a minimally invasive method for primary glossopharyngeal neuralgia with good outcomes,mild surgery-related complications,and quick post-operative recovery.
