Objective:To observe the effect of acupuncture plus medium-frequency electric stimulation on bladder function after radical hysterectomy for cervical cancer. Methods:A total of 170 patients confirmed by biopsy and surgical pathology and treated with radical hysterectomy for cervical cancer were randomly divided into an acupuncture group, an observation group and a control group by random digital table. Fifty-six cases in the acupuncture group were treated with acupuncture after surgery, one session each day, till the extubation day; 58 cases in the observation group were treated with acupuncture plus medium-frequency electric stimulation after surgery, one session each day, till the extubation day; and 56 cases in the control group didn't receive any intervention, and the catheter was retained till the extubation day. On the postoperative day 14, all groups were dealt with catheterization to determine the residual urine volume, in order to observe the occurrence rate of urinary retention and the recovery of bladder function and to compare the differences of the therapeutic effects among the groups. Results:The occurrence rates of urinary retention were respectively 16.1%, 20.7% and 46.4% in the acupuncture group, observation group and control group, with significant differences (P<0.05). When comparing the acupuncture group and the observation group with the control group, there were significant differences (bothP<0.05). In comparison between the acupuncture group and the observation group, there was no significant difference (P>0.05). The recovery rates of bladder function in the three group were respectively 42.9%, 60.3% and 41.1% without significant differences (P>0.05). Moreover, there were no significant between-group differences (P>0.05), but acupuncture plus medium-frequency electric stimulation showed a better tendency. Conclusion: The single application of acupuncture therapy is effective and able to prevent urinary retention after radical hysterectomy for cervical cancer. Acupuncture plus medium-frequency electric stimulation can effectively enhance the recovery of bladder function and reduce the residual urine volume in the bladder to the maximum.

OBJECTIVETo compare the effectiveness and safety of transurethral resection of the prostate (TURP) and transurethral enucleative resection of the prostate (TUERP) in the treatment of benign prostate hyperplasia (BPH).

METHODSA total of 630 BPH patients with indication of surgery were randomly assigned to receive TURP (n = 305) and TUERP (n = 325), respectively. There were no significant differences preoperatively in age, prostate volume, International Prostate Symptom Score (IPSS), and Qmax between the two groups (P > 0.05). The prostate resection rate, operation time, postoperative complications, and quality of life (QOL) of the patients were recorded and statistically analyzed.

RESULTSCompared with TURP, TUERP showed a significantly higher rate of prostate resection ([47.0 +/- 13.3] vs [60.1 +/- 12.3]%, P < 0.05), shorter operation time ([57.9 +/- 15.9] vs [40.4 +/- 14.2] min, P < 0.05), and shorter bladder irrigation time ([2.7 +/- 0.6] vs [2.2 + 1.1] d, P < 0.05). Significant differences were found between the pre- and post-operative levels of serum sodium and hemoglobin in the TURP group ([141.2 +/- 3.5 ] vs [136.9 +/- 4.7] mmol/L, P < 0.01; [137.6 +/- 8.8] vs [124.8 +/- 9.6] g/L, P < 0.01), but not in the TUERP group. Three months after operation, IPSS, QOL, and Qmax were all markedly improved in both groups (P < 0.01), but with no significant differences between the two groups (P >0.05).

CONCLUSIONTUERP is better than TURP in the treatment of BPH for its advantages of higher resection rate of the prostate, shorter operation time and bladder irrigation time, less intraoperative blood loss, fewer postoperative complications, and faster recovery.

Objective To study the adverse effect of house indoor air pollution on children respiratory system health in Lanzhou city.Methods A retrospective questionnaire investigation on 1 700 children respiratory health was carried out in three kindergartens,three elementary schools involving lower grade pupils in three districts in Lanzhou city.At the same time,the information about the home environment of the children and family background was collected.Applying logistic regression model, the influencing factors were analyzed.Results The over-standard rates of indoor air quality were from 12.4% to 43.8% in Lanzhou.In the non-heating period,the over-standard rates of formaldehyde,benzene,SO_2,NO_2,CO and PM10 in indoor air were 22.6%,14.5%,13.3%,12.4%,0% and 23.3% respectively.In the heating period,the over-standard rates of the pollutants were 27.3%,16.4%,34.6%,28.5%,32.3% and 43.8% respectively.Indoor air pollution was statistically associated with children respiratory symptoms and diseases,the related risk factors were someone smoking in home,house decorated,opening windows, ventilation,heating in winter,sharing bedroom and maternal education.The outdoor air pollution was one of the influencing factors. Conclusion Children respiratory diseases and symptoms are related to many air pollution factors,such as outdoor and indoor air pollution,personal characteristic and family factors,so to prevent and control indoor air pollution,a comprehensive way should be taken in Lanzhou city.

In order to solve the problems of erratic drug absorption and low bioavailability after oral administration for poorly-water soluble drugs due to low solubility, a series of novel pharmaceutical dosage forms as solid dispersion, liposome, microemulsion, vesicle, cyclodextrin inclusion complexes and drug nanocrystal have been developed in recent years. Among which drug nanocrystal attracts more attentions for its simpler preparation method, higher drug loading and easier manufacturing technology in the design of dosage forms suitable for different administration routes. In this paper, the nanocrystals of the poorly-water soluble drugs prepared based on bottom-up and top-down technologies were introduced. The characteristics and applications of the nanocrystal-based dosage forms as suspension, tablet and capsule were also introduced and carefully evaluated with the focus on their pharmacokinetics, pharmacodynamics and tissue targeted drug distribution after delivery by oral administration, intravenous injection and pulmonary inhalation. The advantages of drug nanocrystals in their therapeutics effects over the bulk drugs were discussed together with the inherent mechanism. Finally, the problems existing in basic research and scaled-up manufacture of drug nanocrystal as well as the possible ways of solution were listed out so as to make the nanocrystal-based preparations exert their maximum therapeutic effect after clinical application.

Objective To investigate the dynamic changes of serum levels of neuron-specific enolase(NSE),endothelin(ET)and calcitonin gene-related peptide(CGRP)and their clinical significance in the elderly patients with acute cerebral infarction.Methods One hundred and twenty elderly patients with acute cerebral infarction(ACI),60 elderly patients with lacunar infarct,60 elderly patients with hypertension and 60 elderly patients with cerebral artherosclerosis were enrolled. The areas of infarction were measured and the venous blood samples at different times were collected after cerebral infarction to determine the concentrations of NSE,ET and CGRP by radioimmunoassay. Results There were dynamic changes of the plasma levels of NSE,ET and CGRP.In the early time the plasma levels of NSE and ET of the elderly patients with acute cerebral infarction were significantly higher than those of the elderly patients with cerebral artherosclerosis,or with hypertension,or with lacunar infarct(P＜0.01,P＜0.01,P＜0.05,respectively),and were gradually declined along with timing.In ACI group,the level of NSE began to increase gradually after 24 hours,reached the highest in 2 days,and decreased to normal after 14 days,but the level of ET was always higher than those in the cerebral artherosclerosis and hypertension groups.The ET levels in lacunar infarct and hypertension groups were also significantly higher than in the cerebral artherosclerosis group(P＜0.01).However,when compared with the cerebral artherosclerosis and hypertension groups,the plasma concentrations of CGRP in cerebral infarction and lacunar infarct groups were obviously lower(P＜0.01),and increased gradually.We also found the larger the infarction area,the lower the level of CGRP.Conclusions The NSE,ET and CGRP concentrations are associated closely with acute cerebral infaction.Monitoring the level of NSE is applicable for early diagnosis of cerebral infarction.
