Determination of zolpidem tartrate tablets after radiation by UHPLC / 药学实践杂志

Objective To establish a UHPLC method for the determination of zolpidem tartrate tablets after radiation, and to investigate the effect of different radiation doses on the content of zolpidem tartrate tablets. Methods Ultra high performance liquid chromatography was used. The content of zolpidem tartrate tablets irradiated by γ-ray was determined. Using C18 column, acetonitrile methanol-0.05 mol/L phosphoric acid solution (the pH value as 5.5 with triethylamine) (18∶26∶56) was used as the mobile phase. The flow rate was 0.7 ml/min, and the detection wavelength was 254 nm. Results The method validation showed good linearity in the concentration range of 5-80 μg/ml (r=0.999 6); The average recovery was 98.2%, RSD was 1.72%, and the repeatability was 0.87%. The contents of zolpidem tartrate were 105.1%, 106.4%, 102.7% and 105.4% under 0, 8, 25 and 80 kGy radiation. Conclusion UHPLC has accurate results with short analysis cycle in this study. It is suitable for the determination of zolpidem tartrate tablets after radiation. The content of zolpidem tartrate tablets remained basically unchanged after radiation.

Effect of perioperative hypothermia therapy on elderly patients with acute intestinal obstruction / 中国基层医药

Objective To investigate the effects of perioperative hypothermia therapy on immune function and nerve function recovery in elderly patients with acute intestinal obstruction. Methods From January 2010 to December 2015,80 elderly patients with acute intestinal obstruction in the Traditional Chinese Medicine Hospital of Beilun District were selected and randomly divided into two groups,with 40 cases in each group. The control group was given conventional symptomatic treatment during operation,the observation group was given intraoperative hypothermia therapy on the basis of the control group. The CD +4 ,CD +8 ,CD +4 / CD +8 changes of immunoglobulin were observed in the two groups,the ESS(NIHSS) and Barthel index(daily life ability score) were compared between the two groups. Results After intervention,the CD +4 ,CD +8 ,CD +4 / CD +8 levels in the observation group were (35. 1 ±2. 0)％ ,(30. 6 ± 1. 3)％ and (1. 9 ± 0. 3),respectively,which were higher than those in the control group[(26. 0 ± 0. 9)％ ,(24. 4 ± 1. 0)％ and (1. 6 ± 0. 2)],the differences between the two groups were statistically significant(t = 26. 242,23. 908, 5. 262,all P <0. 05). The IgM,IgG,IgA levels in the observation group were (1. 60 ± 0. 03)g/ L,(9. 50 ± 0. 12)g/ L, (3. 90 ± 0. 20) g/ L,respectively,which were higher than those in the control group[(1. 30 ± 0. 02) g/ L,(8. 80 ± 0. 10)g/ L,(1. 80 ± 0. 15)g/ L],there were statistically significant differences between the two groups(t = 52. 623, 28. 342,53. 126,all P < 0. 05). The ESS,Barthel index in the observation group were (78. 6 ± 8. 5),(77. 3 ± 6. 6), respectively,which were higher than those in the control group[(59. 6 ± 6. 1),(62. 6 ± 5. 4)],there were statistically significant differences between two groups(t = 11. 486,10. 902,all P < 0. 05). Conclusion Hypothermia treatment can effectively reduce the effect of surgery on immune function in elderly patients with acute intestinal obstruction, promote the recovery of the nervous system,and improve the quality of life of the patients.

Ultrasound measurement of detrusor wall thickness in equivocal bladder outlet obstruction / 中华泌尿外科杂志

Objective To estimate the application of ultrasound measurement of detrusor wall thickness (DWT) in the assessment of curative effect after operation. Methods Detrusor thickness was measured by linear ultrasound (7. 5 MHz) either at a filling volume of 50% of cystometric capacity or at 250 ml filling in 86 patients, who were diagnosed equivocal BOO, during a pressure-flow study. All patients accepted transurethral resection of the prostate. At 3 months post-surgery, the patients were divided into two groups according to curative effect after operation. The volume of the prostate, age and DWT were compared between the two groups. Results There was no difference in either age or volume of the prostate between the two groups. DWT was significantly higher (P＜0.01) in the more curative effect group (37 cases, DWT 2. 5±0.3 mm) compared to the less curative effect group (49 cases, 2.2±0. 3 mm). As a predictor of curative effect, DWT of 2. 8 mm or greater had a positive predictive value of 100%, a negative predictive value of 62%, specificity of 100% and sensitivity of 19%. Receiver operating characteristic analysis (ROC) revealed that DWT had a high predictive value for curative effect post-surgery with an AUC of 0. 84±0. 04. Conclusions In patients with equivocal BOO, ultrasonographically assessed detrusor thickness may have a predictive value for curative effect post-surgery. However, this cutoff value needs to be validated in a larger study population.

Ultrasonic measurement of intravesical prostatic protrusion in benign prostatic hyperplasia patients / 中华泌尿外科杂志

Objective To study a noninvasive method in evaluating the bladder outlet obstruc-tion (BOO) and bladder function in patients with benign prostatic hyperplasia (BPH) based on the transabdominal ultrasonic measurement of intravesical prostatic protrusion (IPP). Methods The da-ta of 206 first visit BPH patients with lower urinary tract symptoms (LUTS) were retrospectively re-viewed. Patients were divided into 2 groups based on the degree of IPP: the research group with IPP greater than 10 mm(n=78) and control group with IPP 10 mm or less(n=128). Clinical data and uro-dynamic findings of the 2 groups were analyzed to find the clinical significance of IPP. Resells In-creased prostate volume(73.7±35.9 ml vs 62.8±36.5 ml), serum prostate specific antigen(1.81± 0.67 ng/ml vs 1. 64±0.36 ng/ml), post-voiding residual urine volume (PVR)(290.2±217.2 ml vs 228.2±167.9 ml), incidence of acute urine retention(33.3% vs 18.0%)and bladder trabeculation (23.1% vs 11.7%)had signicant differences between the 2 groups (P<0.05). Positive correlation was found between IPP and prostate volume as well as PVR (r=0.401 and 0.342, respectively). In the urodynamic study, significantly lower peak flow rate (Qmax) (7.6±4.1 ml/s vs 9.1±3.6 ml/s), higher incidence of detrusor overactivity (82.1% vs 17.2%) and low bladder compliance (35.9% vs 12.5%)were found in research group (P<0.01). In addition, maximum detrusor pressure(109.8± 84.9 cm H2O vs 84.9±44.1 cm H2O) and BOO index (BOOI) (75.2±27.1 vs 65.9±34.6) were significantly higher in the research group (p<0.05). The correlation study showed that r between IPP and Qmax, Pdet. max and BOOI was-0.284, 0.252 and 0.456, respectively. The incidence of acute urinary intention recurrence was higher in research group than in control group (64.3% vs 23.5%) (P<0.05). Conclusions IPP is a useful predictor in evaluating BOO and detrusor function. BOO and impaired detrusor function in obvious IPP patients are more severe. The obvious IPP pa-tients, especially those presenting with acute urine retention, may benefit more from early surgical in-tervention.

Effects of active fractions L.F04 from ground part of Lycopus lucidus var.hirtus on platelet aggregation and thrombosis formation / 中草药

Object To study the effects of active fraction L.F04 from the ground part of Lycopus lucidus Turcz. var. hirtus Reg. on platelet aggregation and thrombosis formation and investigate its mechanisms of promoting blood circulation and removing blood stasis. Methods The effects of L.F04 on platelet aggregation induced by ADP in vivo, thrombosis of artery vein side road and thrombus formed in rotary loop in vitro were examined, the rat model of blood stasis made by injecting high molecular weight dextran (HMWD) was used. Results L.F04 0.408 and 0.204 g/kg evidently inhibited the ADP induced increase of platelet maximum aggregation rate in vivo in HMWD model, with a concentration dependent manner. Compared with the control group, the thrombus weight in rat model of blood stasis was increased significantly and the length of thrombus was shown an increasing trendency. L.F04 0.408 and 0.204 g/kg both shown the anti thrombosis effect. L.F04 0.408 g/kg showed better effects of lessening the thrombus dry weight and wet weight. Both L.F04 0.408 and 0.204 g/kg could inhibit the thrombosis of artery vein side road, the inhibition rates are separately 27.41% and 27.14%. Conclusion L. lucidus var. hirtus F04 could significantly inhibit platelet aggregation and thrombosis formation.
