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.

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.

OBJECTIVE:
To investigate the clinical manifestation, diagnosis, treatment of parathyroid occupying lesions.
METHOD:
The clinical data of 26 patients with parathyroid occupying lesions between January 2003 and October 2012 at Dalian Central Hospital were retrospectively analyzed.
RESULT:
There were 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma, 13 cases of parathyroid cysts in this study. All the cases,except 13 cases of cysts, are accompanied by symptoms of hyperparathyroidism. The symptoms were as follows:26 cases of neck lump, 11 cases of osteoporosis/osteitis fibrosa cystica,9 cases of urinary symptom, 8 cases of digestive symptom. Serum calciumion level and serum parathyroid hormone(PTH) level were examined qualitatively before operation. Ultrasonography, CT, MRI were used in diagnosing and locating parathyroid occupying lesion before operation. 2 cases of parathyroid cancer, 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts with preoperative and postoperative diagnosis coincidence rate was 0 (0/2), 91% (10/11), 69% (9/13). All patients were treated with operation. 2 cases of parathyroid cancer survived with out recurrence during follow up for 17 months and 27 months after operation. 11 cases of parathyroid adenoma and 13 cases of parathyroid cysts were treated with operation,achieved complete remission and the outcome was no recurrence.
CONCLUSION
There lack of specific clinical symptoms of parathyroid occupying lesions,neck lump are common manifestations. Examination of serum calcium and PTH level together with ultrasonography, CT, MRI, 99mTc-MIBI is helpful to diagnose parathyroid occupying lesions. Parathyroid cancer preoperative diagnosis is difficult . Parathyroid occupying lesions determine the diagnosis depends on pathology. Surgery should be done as primary treatment.
