Objective:To establish an HPLC method for the simultaneous determination of methionine, vitamin B1 and vitamin B2 in Lingzhi Erwei methionine capsules. Methods:The determination was performed on a Ultimate? AQ-C18 column(250 mm × 4. 6 mm, 5 μm,Welch Inc. ) with the detection wavelength at 220 nm. The mobile phase was composed of methanol and 0. 07 mol·L-1 sodium heptanesulfonate solution (14 ml triethylamine diluted with water to1 000ml, adjusting pH to 3. 5 with diluted orthophosphoric acid) with gradient elution, and the flow rate was 1. 0 ml·min-1. Results: Methionine, vitamin B1 and vitamin B2 was in good linearity within the range of 0.527 0-1.510 0 mg·ml-1 - (r =0.999 9), 0.045 52-0.136 56 mg·ml-1 (r =0.999 9) and 0.010 10-0. 060 58 mg·ml-1(r=0. 999 9), respectively. The mean recovery was 100. 5%, 97. 7% and 101. 5% with RSD of 0. 5%, 1. 0%and 1. 4%(n=9) accordingly. Conclusion:The method is simple, accurate, reliable and appropriate in the simultaneous determina-tion of methionine,vitamin B1 and vitamin B2 in Lingzhi Erwei methionine capsules.

Objective To research the relationship among the disc protrusion on MRI, sex, age, course and the clinical types. Methods MRI was performed for 102 patients. The disc protrusion was divided into three types. According to clinical types, the patients were divided into four types. Statistically, age, course, clinical type and protrusion on MRI were analyzed by SPSS13.0. Results The age was not related with the clinical types and disc protrusion on MRI. There were obvious relations between clinical types and course. There were obvious relations between clinical types and disc protrusion. Conclusion The clinical types are very important on diagnosis of disease stages and choice of therapy in treating lumbar disc protrusion.

Objective To approach the capacity of erythrocyte regulating IL-8 in patients with primary hepatocarcinoma (PHC) by a new experimental system of hemaimmune. Methods 0.2ml suspension of cancer cells (S180: 5?10~6/ml) or NS were added into 0.2ml anticoagulant suspension of whole blood cells or leukocytes and 0.3ml plasma, then incubated for 1 h at 37℃. The content of IL-8 was determined by ELISA. Results In the patients with PHC, the IL-8 levels (pg/ml) in experimental and control groups of whole blood cells, and in experimental and control groups of leukocytes were 376.35?243.96, 353.64?271.92, 461.27?277.11 and 424.97?278.93, respectively; while in the normal human, they were 11.36?6.93, 4.98?4.35, 29.41?30.66 and 20.77?24.20, respectively. In the patients with PHC, the activation rates of cancer cells in the experimental groups of both whole blood cell and leukocyte were 0.22?0.24 and 0.25?0.53, respectively; while in normal human, they were 2.49?2.33 and 0.75?0.21, respectively. In the patients with PHC, the IL-8 adsorption rate of erythrocyte in both experimental and control groups of whole blood cell were 0.22?0.18 and 0.17?0.33, respectively; while in normal human, they were 1.18?2.29 and 0.86?0.49, respectively. The IL-8 activated rates of erythrocyte in the patients with PHC was much lower than in the normal human (P

Objective To investigate the corrective effect of modified Brisson technique to treat concealed penis in children.Methods From July 2014 to July 2016,selected 12 patients (3-10 years old,mean 7.2 years old) with concealed penis were surgically treated with the modified Brisson technique in the Second Affiliated Hospital of Nanjing Medical University.Their clinical manifestations included the penis buried below the surface of prepubic skin which can be palpated and visualized through pushing the skin around the penis to the pubis and the short foreskin which was not attached to the penile corpus cavernosum.Patients with other conditions such as obesity and penial agenesis that caused buried penis were excluded from the study.The modified Brisson technique consisted of 4 steps.Ventral incision was used to gradually slit the narrow ring of the prepuce and to expose the glans followed by circumfe-rential inner foreskin incision made below the coronary sulcus of penis then the foreskin stripping released the corpus cavernosum.Finally the skin coverage was accomplished by posthioplasty.The operation time,blood loss,complications,postoperative treatments and followed-ups were retrospectively analyzed.Results For all the 12 patients,the operations were successful,lasting 40 to 60 minutes.The bleeding was about 5 to 10 mL and there was no operation-related complications like bleeding and infection of incision.Satisfactory cosmetic outcomes were obtained without retraction and the scars were similar to those of circumcision.All patients had penile lymphedema postoperatively which disappeared within 6 months after operation.Follow-up ranged from 6 months to 1 year,and there were no complications like skin necrosis and contracture or voiding difficulty.Conclusions The modified Brisson technique for concealed penis repair is technically easy and safe.In addition,it provides a good cosmetic appearance,functional outcomes and excellent postoperative satisfaction grades.

Objective To understand the incidence.mortality and risk factors of ventilator -associated pneu-monia(VAP)in surgical intensive care unit among elderly patient,in order to direct the clinical prevention and treat-ment of VAP.Methods Retrospective analysis was used on 65 cases of mechanical ventilation elderly patients in our hospital nearly 3 years.Results The incidence of VAP was 66.2%.The mortality of VAP was 67.4%.The factors of long-term mechanical ventilation,high APACHE Ⅱ score,low Glasgow score and inappropriate initial antimicrobial therapy were influenced the prognosis of VAP.Conclusion The incidence of VAP can be decreased and the cure rate can be increased by some effective measures in SICU.

Objective:To investigate whether transplantation of mesenchymal stem cells(MSCs)through renal arteries can protect kidney from acute tubular necrosis(ATN),so as to lay a foundation for MSC transplantation in treatment of ATN.Methods:Five-week-old nude mice were randomly divided into three groups:normal control group(n=10),acute tubular necrosis(ATN)model group without(n=10)and with MSCs treatment group(n=11).ATN nude mice were induced with 50% glycerin.MSCs labeled with enhanced green fluorescent proteins(EGFP)were injected into kidney through renal arteries.Serum creatinine was determined in all groups and pathological changes of renal tissues were detected using H-E staining.The amount and distribution of the EGFP-marked MSCs in renal tissues were determined with fluorescence microscope.Results:Degeneration and exfoliation of renal tubular epithelial cells,and even renal tubular tamponade with cast-off cells were observed in the ATN group;these pathological changes were mainly located at renal cortex and juncture of renal cortex and medulla.The damages were greatly alleviated in the ATN+MSCs transplantation group,with no swelling of epithelial cells,nuclear condensation or edema.Fourteen days after MSCs transplantation,EGFP positive cells were increased in renal tubules of recipient mice.Conclusion:The MSCs transplantation via renal artery can locate in renal tubular epithelium,and promote the repair of injured renal tubular epithelial cells.

AIM:To explore the roles of Akt ( also called protein kinase B ) and active caspase-3 in the leptin-mediated chronic morphine antinociceptive tolerance in rats .METHODS: A model of chronic morphine antinociceptive tolerance was established in the SD rats .The protein levels of spinal Akt and cleaved caspase-3 were tested by Western blotting.The technique of immunohistochemical staining was used to detect the immunoreactivity positive cells of phospho -rylated ( p)-Akt and cleaved caspase-3 in the spinal cord .Double staining of immunohistochemistry was used to examine the cellular location of the p-Akt and cleaved caspase-3 positive cells.RESULTS: The chronic intrathecal injection of morphine (15 μg) for 7 d markedly upregulated the spinal protein levels of p-Akt and cleaved caspase-3 in the rats.Thirty min before injection of morphine , intrathecal injection of leptin antagonist (3μg) for 7 d significantly attenuated the upreg-ulation of the protein levels of p-Akt and cleaved caspase-3 induced by chronic morphine treatment .The p-Akt was exclu-sively observed in the spinal neurons .The cleaved caspase-3 was only localized with the spinal astrocytes .Intrathecal injec-ting the inhibitors of leptin , Akt and caspase-3 ameliorated the chronic antinociceptive tolerance .CONCLUSION: The spinal Akt pathway and active caspase-3 are involved in the leptin-mediated chronic morphine antinociceptive tolerance in rats.
