National Journal of Andrology 2014;20(3):249-252
OBJECTIVETo investigate the feasibility and effect of early removal of the urethral catheter after transurethral plasma kinetic resection of the prostate (PKRP) in the treatment of benign prostatic hyperplasia (BPH).
METHODSWe equally randomized 128 BPH patients treated by PKRP to an experimental group and a control group, urethral catheters removed at 1 -2 days for the former and at 5 -7 days for the latter. We compared the relevant indexes and clinical effects between the two groups.
RESULTSThe baseline data were not significantly different between the two groups. Compared with the controls, the experimental group showed a significantly shorter postoperative hospital stay ([6.8 +/- 1.9] d vs [3.7 +/- 1.5] d, P < 0.05) and lower infection rate (25.0% vs 10.9%, P < 0.05). All the patients were followed up for 3 -6 months postoperatively. At 3 months after surgery, both the experimental and the control groups showed remarkable improvement in the International Prostatic Symptoms Scores (4. 9 +/- 2. 2 vs 5. 3 +/- 2. 3), maximum urine flow rate ([21.5+/- 5.6 ] ml/s vs [19.1 +/-4.9 ] ml/s) , and residual urine ( [ 16.8+/- 10.3 ] ml vs [18.9 +/- 12.3 ] ml), but with no significant differences between the two (P > 0.05) , and no significant differences were observed in postoperative complications (P >0.05).
CONCLUSIONEarly removal of the urethral catheter after PKRP, with its advantages of shorter postoperative hospital stay, lower infection rate, and no influence on the long-term effect, deserves to be recommended as a routine method in the treatment of BPH.

Objective To evaluate the damaging degree of hepatic cell in the patients with hepatocirrhosis. Methods 25 cases of hepatocirrhosis and 13 eases of normal controls were performed the dynamic imaging with 99mTc-EHIDA.By the three compartmental model configurations,the time-activity curers of the liver cell,and the function indexes liver cell extraction and excretion were calculated.Results The peak time and mean residence time in the hepatocirrhosis group were higher than those in the normal controls(P<0.01).Compared to normal controls, the peak value,index of uptake,take slope,and excretion slope of the hepatocirrhosis were all lower(P<0.01).Con- clusion Liver cell imaging is a better method for reflecting the change of liver cell function,and may be used to analyse the degree of hepatocirrhosis.

Glioma is the most common form of brain cancer. Despite recent advances in the treatment of solid tumors, there are few effective treatments for malignant gliomas due to its infiltrative nature. It has important significance to improve the treatment of glioma through in-depth understanding the intracerebral metabolic characteristics and pharmacokinetics of chemotherapeutics. Brain microdialysis (B-MD), an effective method to monitor central nervous system anticancer drug disposition, conditions of drugs through the blood-brain barrier, basic pathophysiologic metabolism, bioactive compounds and the changes of neurotransmitter in brain, provides the unique opportunity to allow the simultaneous determination of unbound concentrations of drugs in several tissues, and directly measure gliomas biochemistry continuously. B-MD has been able to monitor the change of brain drugs, metabolites and neurotransmitters, dynamic analysis of the drug concentration and pharmacological effect after administration, pharmacodynamic interaction between drugs, receptor mechanism of drug transport, as well as feedback information of internal environment. B-MD is expected to provide reference for clinical individual chemotherapy of glioma, but also provide powerful tools for the evaluation of new anticancer drugs in vivo. In this review, a comprehensive overview of B-MD for studies on glioma is elucidated with special emphasis on its application to neurochemistry and pharmacokinetic studies.

To study the chemical constituents from Zanthoxylum simulans and their anti-inflammatory activity. The constituents of Z. simulans were isolated and purified using various column chromatographies. Their chemical structures were elucidated using extensive spectroscopic methods. The compounds were assayed inhibitory activity against NO production in LPS stimulated RAW 264.7 cells. Four compounds were obtained from the ethanol extract of Z. simulans and determined to be isozanthpodocarpin B(1), kobusin (2), (+)-fargesin (3), and epieudesmin (4). Compound 1 exhibited NO production inhibitory effect with IC50 value of 14.49 µmol · L(-1). Compound 1 is a new dimeric lignan and may be serve as potential anti-inflammatory agent in the future.

Objective To analysis the long-term retention rate of Levetiraceram (LEV) monotherapy or combination therapy of infant epilepsy. Methods The clinical data of patients with infant epilepsy treated by LEV had been retrospectively analyzed from July 2006 to June 2007. Results Sixty patients with infant epilepsy treated by LEV had been recruited, 20 cases with partial seizures, 19 cases with generalized seizures, 21 cases with epilepsy syndrome. Among them 21 cases was intractable epilepsy. The retention rates of LEV in 6-month, 1-year, 2-year, 3-year and 4-year were 95.5%, 75.0%, 60.0%, 51.7%, and 38.3%. The most common reason for withdrawal was lack of effect (43.2%). COX regression model suggested that duration>1 month (RR=2.91, 95%CI:1.16~7.30) and refractory epilepsy (RR=2.30, 95%CI:1.22~4.32) were risk factors of withdrawal (all P<0.05). After treatment, the seizure frequency signiifcantly reduced compared with baseline (P<0.01). To the end of the follow-up, the efifciency was 100%and the complete remission rate was 69.57%in 23 cases continued treatment. The main side effect were fatigue (56.0%), and sleep increased, irritability, and so on. Conclusions LEV monotherapy or combination therapy has well long-term retention rate, maintains well efifcacy and tolerability in infant epilepsy.
