Objective It was reported that p53 apoptotic peptide (N37) could inhibit p73 gene through being bound with iASPP, which could induce tumor cell apoptosis. To further explore the function of N37, we constructed the cloning plasmid of DNA fragment encoding p53 (N37) apoptotic peptide by using DNA synthesis and molecular biology methods. Methods According to human p53 sequence from the GenBank database, the primer of p53(N37) gene was designed using Primer V7.0 software. The DNA fragment encoding p53 (N37) apoptotic peptide was amplified by using self-complementation polymerase chain reaction (PCR) method and cloned into the pGEM-T Easy vector. The constructed plasmid was confirmed by endonuclease analysis and sequencing. Results The insertion of objective DNA fragment was confirmed by plasmid DNA enzyme spectrum analysis, p53 (N37) gene was successfully synthesized chemically in vitro. The sequencing result of positive clone was completely identical to the human p53(N37) sequence in GenBank using BLAST software (http://www. ncbi. him. nih. gov/cgi-bin /BLASTn). Conclusion The cloning of DNA fragment encoding p53(N37) apoptotic peptide was constructed by using DNA synthesis and pGEM-T Easy cloning methods. With the constructed plasmid, we could further investigate the function of N37 peptide.

Objective To assess the feasibility, safety and curative effect of permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy for the treatment of non-small cell lung carcinoma (NSCLC) in aged patients. Methods CT-guided permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy was performed in 46 patients with NSCLC, of whom 26 received primary treatment and 20 underwent renewed treatment. During the procedure, ~(125)I seeds were embedded into the tumor in all the patients. Three to five days after the implantation, GP scheme chemotherapy started. GEM (1 000 mg/m~2) was given (intravenously dripping for 30 min.) on the 1st, 8th and 15th day; DDP (30 mg/m~2) was employed on the 1st, 2nd and 3rd day, and recombinant human endostatin (Endostar, 7.5 mg/m~2) was administered (intravenously dripping for 3-4 hours) from the 1st to the 14th day. Every 28 days completed one treatment course. Two months after ~(125)I seed implantation, at this time the patient had received two courses of treatment, the short-term effect and the toxic side-effect were evaluated. Results Two months after the ~(125)I particles were embedded in the tumor, all the 46 cases were able to be evaluate for the curative effect. Of 46 patients, complete relief (CR) was seen in 12, partial relief (PR) in 24, stable (SD) in 6 and progression (PD) in 4, with an effective rate of 78.26%. Of 26 patients in the primary treatment group, CR was obtained in 7, PR in 15, SD in 3 and PD in 1, with an effective rate of 84.6%. Of 20 patients in the renewed treatment group, CR was seen in 5, PR in 9, SD in 3 and PD in 3, with an effective rate of 70.0%. Conclusion Permanent implantation of ~(125)I seeds combined with GP scheme chemotherapy is an effective, safe and feasible treatment for NSCLC in aged patients.

0.05).Conclusions The chemotherapeutic embedding radioactive particle 125Ⅰ combined with GP is safe,feasible,and effective to the therapy of senile-inoperable NSCLC.

OBJECTIVE To clarify the features of nosocomial infections for patients with multiple myeloma(MM).METHODS One hundred and seventy eight cases of MM treated in our hospital from Oct 1982 to Dec 2006 were analyzed retrospectively.RESULTS Eighty five patients(47.8%) suffered from nosocomial infections.The nosocomial infection took place more frequently on respiratory tract.Elder,granulocytopenia,hypoproteinemia,severe anemia,and diabetes were the risk factors.Totally 91 pathogens were isolated.Gram-negative bacilli accounted for 45.1%,and were the major pathogens.Fungi accounted for 37.4% and Gram-positives accounted for 17.6%.The ESBLs producing strains accounted for 31.6% in Klebsiella pneumoniae and Escherichia coli.Vancomycin resistant strains were found.The top one of fungi presented organism was the Candida albicans.CONCLUSIONS Nosocomial infections for patients with multiple myeloma has a high incidence.There are many risk factors.The resistance of commonly encountered bacteria to antimicrobial agents is a serious problem.Immunity protection and the rational use of antimicrobial agents should be emphasized.

ObjectiveTo explore the clinical effects of forearm cutaneous neurovascular flaps to be used on repairing remote wound.Methods17 cases of soft tissue defect of head and facial region and upper extremity were repaired with forearm cutaneous neurovascular flaps.Results The flaps of 16 cases were entirely survived, partial necrosis appeared in 1 case and healed after changing dressing.Following up for 3 to 6 months, the quality and shape of all the flaps and function recovery of all patients were satisfied.ConclusionsWith adequate blood supply, the survival rate of forearm cutaneous neurovascular flaps is high and the procedure to repair remote wound is easy, and it is one of best ways to repair the soft tissue defect in head and facial region and upper extremity with forearm cutaneous neurovascular flaps.

Objective To evaluate the effect of dexmedetomidine on noise-induced hearing loss in guinea pigs.Methods Twenty-four adult male guinea pigs,aged 3 months,weighing 400-500 g,were randomly divided into 3 groups (n =8 each) using a random number table:dexmedetomdine group (group D),noise-induced hearing loss group (group N) and dexmedetomidine + noise-induced hearing loss group (group DN).A loading dose of dexmedetomidine 5 μg/kg was infused over 5 min,followed by 135 min of infusion at a rate of 10 μg· kg-1 · h-1.The equal volume of normal saline was infused in group N.Groups N and DN were exposed to noise of 4 kHz center frequency and 118-122 dB SPL for 120 min starting from 20 min of administration.Mean arterial pressure (MAP) and cochlear blood flow (COBF) were recorded before administration and every 5 min during drug administration.The changing rate of COBF was calculated.Arterial blood samples were collected for determination of plasma concentration of noradrenaline (NE) by high performance liquid chromatography at 20 and 140 min of administration.Auditory brainstem response (ABR) threshold was recorded before administration and at 1 and 72 h and 10 days after the end of administration.Results Compared with group N,MAP was significantly decreased,the changing rate of COBF was increased at 5-10 min and 30-140 min of administration,ABR threshold was decreased at 1 and 72 h and 10 days after the end of administration,and the plasma concentration of NE was decreased at 140 min of administration in D + N group (P ＜ 0.05).Conclusion Dexmedetomidine can attenuate noise-induced hearing loss in guinea pigs possibly through inhibiting activation of sympathetic nerves and increasing COBF.
