Objective To evaluate the clinical efficacy of ultrasound-guided percutaneous pneumatic nephrolithotomy combined with ultrasonic lithotripsy in the treatment of renal calculi.Methods Fifty-nine patients with complicated renal calculi(ranged from 2.8 to 7.0 cm in diameter measured by KUB),including 36 patients with unilateral calculi and 23 patients with bilateral calculi,received percutaneous nephrolithotomy by using ultrasonic and pneumatic lithotripter(EMS Ⅲ),puncture hard wire,and mental dilator.A track from the skin surface into the kidney was established under the guidance of B ultrasonography.Results 82 tracks in the 59 patients were successfully established.The mean operation time was 90 minutes(45-150 minutes),and the management time of stones was 30-70 minutes.Residual stones were found in 15 kidneys and were removed by extracorporeal lithotripsy or two stage lithotripsy two weeks after operation.The clearance rate of stone in one session and two sessions was 82%(67/82) and 93%(14/15),respectively.Hospital stay was 5-15 days(mean,10 days).A follow-up of 1-6 months(mean,3.2 months) in 59 cases showed no severe bleeding,infections,and stone recurrence.Conclusions Ultrasound-guided percutaneous pneumatic nephrolithotomy combined with ultrasonic lithotripsy for complicated renal calculi is characterized by high efficiency,safety and minimal invasion.

The studying in the department of medical imaging is a vital part of the standardized training for resident,which is important to make appropriate and efficient training schedule for the improvement of residents' diagnostic capability.At present,the standardized training for resident doctors of traditional Chinese medicine is lack of enough attention and effective teaching plan.In view of the current situation of poor imaging basis,short rotation time and the lack of educational programs in clinical doctors of traditional Chinese medicine,we achieved significant training effect through a series of systematic training programs such as using the theory of teaching,PPT teaching,informatization teaching,individuation teaching and so on.

Graphene ( GN) and multiwalled carbon nanotubes ( MWCNT) composites were coated on glassy carbon electrode ( GCE ) and then poly ( nicotinic acid ) ( PNA ) was electrodeposited on the modified electrode. The electrochemical behavior of pyridoxine hydrochloride ( VB6 ) was investigated at the modified electrode by cyclic voltammetry ( CV ) and differential pulse voltammetry ( DPV ) . Results showed the oxidation current of VB6 at the GN-MWCNT/PNA/GCE was obviously larger than that at GCE, PNA/GCE and GN/MWCNT/GCE. The oxidation process of VB6 was an irreversible diffusion-controlled process involving one electron and two protons. The liner range between the peak current intensity of DPV and the concentration of VB6 was 0 . 05-200 μmol/L with a detection limit of 0 . 02 μmol/L ( S/N=3 ) . The modified electrode showed a good reproducibility with a relative standard deviation of 3 . 1% ( n=8 ) . The proposed method was applied to the analysis of vitamin B6 in vitamin B6 tablets and compound vitamin B tablets with recoveries between 96 . 1%-104 . 5%.

Objective To evaluate laparoscopic local resection for the treatment of gastric tumors. Methods The clinical data of 78 patients who received laparoscopic local resection at the PLA General Hospital from February 2006 to January 2010 were retrospectively analyzed. According to the tumor site and free range, total laparoscopic gastrectomy was applied to 45 patients, laparoscopic local resection was applied to 22 patients, laparoscopic and endoscopic tumor resection was applied to 11 patients. The efficacies of the surgical approaches were investigated. Results Laparoscopic local resection was successfully performed on the 78 patients without conversion to open surgery. The mean operation time and operative blood loss were 75 minutes (range, 45-120 minutes) and 60 ml (range, 35-90 ml), respectively. The mean diameter of the tumor was (2.5±1.3)cm (range, 0.7-4.8 cm). No mortality or morbidity occurred postoperatively. The bowel function recovery time and the duration of hospital stay were 35 hours (range, 25-42 hours) and 7.5 days (range, 6-9 days), respectively. The results of postoperative pathological examination verified that 63 patients were with gastric stromal tumor, 11 patients were with benign gastric diseases, including 5 with gastric heterotopic pancreas, 2 with inflammatory pseudotumor, 2 with hyperplastic polyp, 1 with schwannomas and one with angioma. Four patients were with carcinoid, 3 carcinoids were located in mucous layer and 1 invaded into muscular layer. The median time of follow-up was 26 months, and no anastomotic stenosis or port-site metastasis was observed. Of the 63 patients with gastric stromal tumor, 2 were treated with imatinib mesylate, 1 had tumor recurrence and received reoperation. Conclusion Laparoscopic local resection is safe and feasible for the treatment of benign gastric neoplasms, stromal tumor and early gastric tumors.

Objective To investigate the clinical influence about levetiracetam on cognitive function and emotional influence in the patients with partial epilepsy.Methods A total of 62 patients with partial epilepsy were divided into carbamazepine group (30 cases) and levetiracetam group (32 cases) by random digits table method,carbamazepine group was treated by carbamazepine while levetiracetam group was treated by levetiracetam.The patients were assessed before treatment and 4,8,12,16 weeks after treatment by the Montreal cognitive assessment scale (MoCA),self rating anxiety scale (SAS) and self rating depression scale (SDS).Results There was no significant difference in MoCA score between two groups before treatment and 4 weeks after treatment (P ＞ 0.05).MoCA score at 8,12,16 weeks after treatment in levetiracetam group was better than that in carbamazepine group [(22.6 ± 2.1) scores vs.(20.8 ± 2.6) scores,(23.5±2.7) scoresvs.(21.3± 2.8) scores,(24.6±4.7) scoresvs.(21.2±3.0) scores],the difference was statistically significant (P ＜ 0.05).There was no significant difference between SAS score,SDS score between two groups before and after treatment (P ＞ 0.05).Conclusion In the process of treating the patients with partial epilepsy by drug,levetiracetam is superior to carbamazepine on the improvement of cognitive function,but the mood improvement is not obvious.

OBJECTIVE: To investigate the expression and clinical pathological significance of PDCD4 in laryngocarcinoma tissue and its potential significance to clinic. METHOD: Western-blotting and immunohistochemistry ana lyse to measure the protein expression of PDCD4 in 54 cases of laryngocarcinoma tissues (studying group) and their paraneoplastic normal tissues (control group). The correlations of PDCD4 with clinical pathological parameters were analyzed. RESULT: PDCD4 protein was positively expressed in paraneoplastic normal tissue while which was lost or decreased in laryngocarcinoma tissue by Western blot and immunohistochemistry. Immunohistochemistry assay showed the location of PDCD4 protein in cells was different between the studying group and the control group. The expression level of PDCD4 was related to the pathological grades of the laryngocarcinoma. It's higher in the well-differentiated tumor group than that in the poorly differentiated ones. But the expressions of PDCD4 were no differences among other clinical parameters including sex, age, clinical classification, clinical stage and the cervical lymphonodus who had been metastases or not. CONCLUSION PDCD4 gene is anti-oncogene. It may play an important role in the pathogenesis and development of laryngeal carcinoma and it may be a new target of therapy for laryngo carcinoma.
