The effects of different concentrations of enflurane and enflurane/nitrous oxide on EEG in 20 patients (ASA grade Ⅰ) were studied during elective surgery. They were divided randomly into two groups:enflurane (E) group (n=10) and enflurane/nitrous oxide (EN) group (n= 10). Anesthesia was induced by inhaling enflurane or enflurane/60% nitrous oxide. After intubation patients were venti lated mechanically to maintain P_(ET)CO_2 4.27—4.93 kPa, Two-leads EEG monitor was used during operation. 95% spectral edge frequency (SEF),MAP and HR were recorded in group E at 0.5,0.8,1.0,1.3 and 1.5 MAC, and in group EN at 0.8,1, 0,1.3,1.5,1.8 and 2.0 MAC. SEF decreased in linear manner,but MAP insignificantly changed as enflurane level increased. SEF was smaller in group E than that in group EN under the same additive MAC value, In raw EEG,patients in group E had spike wave at more than Ⅰ.0 MAC,but there was no spike wave in group EN. So enflurane/nitrous oxide anesthesia is more proper because nitrous oxide diminishs the undesirable effects of enflurane on brain during deeper anesthesia. The simple additive MAC value may not reflect the exact anesthesia level when nitrous oxide is used in combination, but SRF can do it.

Objective To explore the relation among the quality of the Paridis polyphylla and different species and growth conditions, and help to provide scientific foundation for introduction and cultivation of Paridis polyphylla.Methods The samples of Paridis polyphylla were collected by different varieties, different growth years, different harvest seasons and different altitude habitats. The content of saponins in Paridis polyphylla was measured by HPLC method according to the Chinese Pharmacopoeia 2015. The chromatographic column was ACQUITY UPLC? HSS T3 (3.0 mm× 100 mm, 1.8μm), the mobile phase was acetonitrile and water (gradient elution), with flow rate of 0.5 ml/min, detection wavelength was 203 nm and column temperature at 35℃.Results Total saponin content ranged from 1.35% to 3.89% among the varieties studied. The content of each components were listed as:Paris polyphylla Smith(PS) >Paris polyphylla Smith var. yunnanensis(Franch.) Hand.-Mazz. (PY) >Paris polyphylla Smith var. chinensis(Franch.) Hara (PC). From 3 to 10 years old of PC, the longer the growth years made the higher the total saponin content. Furthermore, total saponin content of PC increased gradually with the altitudes rising from 400 to 800 meters. The total saponin content of PY harvesting in spring was much higher than that of other seasons.Conclusions The Results showed the importance for introducing and cultivating of Paridis polyphylla.

Objective To investigate the causes and outcome of different treatment methods of iatrogenic rectovaginal fistula. Methods Clinical data of 52 patients with iatrogenic rectovaginal fistula were analyzed retrospectively. Results Twenty-two fistulae occurred after gynecological operation (42.3%), fourteen after obstetric injury (26.9%), thirteen after colorectal operation (25.0%) and three due to miscellaneous causes (5.8%). The fistulae were located in the lower rectum in 27 cases(51.9%), mid rectum in 10 cases(19.2%) and upper rectum in 15 cases(28.9%). They were treated by non-surgical treatment in 9 cases(17.3%), permanent diverting stoma(loop transverse colostomy) in 8 cases(15.4%), and surgical repair by various approaches in 35 cases(67.3%). The fistulae of all nine patients who received non-surgical treatment failed to heal. Eight patients who received permanent diverting stoma had symptomatic improvement without fistula healing. The overall cure rate of surgical repairs in 35 cases was 77.1%(27/35). The cure rates of trans-sphincteric (Mason′s operation), transanal, transabdominal, transperineal and transvaginal approaches were 100%(8/8), 100%(2/2), 83.3%(5/6), 0%(0/1) and 66.7%(12/18), respectively. The cure rate of Mason′s operation for the mid and lower rectovaginal fistulae was higher than that of transvaginal approach (100% vs 66.7%). Conclusions Iatrogenic rectovaginal fistula is caused by obstetric injury or injury of rectovaginal septum due to surgical mismanagement. Surgical repair is the only method that can cure rectovaginal fistulae. Mason′s operation is a favorable treatment method for the mid and lower (especially mid) rectovaginal fistulae.

Objective To evaluate the clinical features and treatment of pelvi-ureteric junction obstruction (PUJO) in a duplex kidney. Methods From 1993 to 2010, 752 patients were diagnosed as PUJO in our hospital and 18 patients (2.4%) with PUJO in duplex kidneys. Three patients had obstruction in the complete duplicated systems and 15 in the incomplete duplicated systems. Five patients had obstruction of the upper moiety and 13 of the lower moiety. All of the 18 patients underwent B-ultrasonography, with 15 enhanced CT scan, 11 intravenous urography and 10 retrograde pyelography.All patients had serum creatinine test after admission and during the follow-up. Results Sixteen patients underwent operations and 2 patients were treated conservatively. Nine patients underwent pyeloplasty and 7 patients underwent heminephroureterectomy. Pathology shows derangement of the lamina muscularis at pelvi-ureteric junction and infiltration of inflammatory cells in mesenchymal. They were followed up from 6 months to 3 years with a mean of 24 months. The clinical symptoms of patients who underwent surgery were cured in all cases. B-ultrasound and IVU showed that hydronephrosis was obviously relieved and the levels of serum creatinine remained the same or decreased. The hydronephrosis and serum creatinine of patients who underwent conservative treatment remained stabilized. Conclusions PUJO in duplicated system is a rare condition. Careful preoperative evaluation is needed to reach the final diagnosis and retrograde pyelography has high specificity. Treatment should be individualized according to split and partial renal function.

AIM　To discuss the intraspecific relationship in Magnolia officinalis and the genuineness of Cortex Magnoliae officinalis, and to find some DNA characters of certified “Houpo”. METHODS　Thirty-three samples from eleven locations, which can represent most of the distribution of M.officinalis, were selected. The total DNA was extracted. Severty-four random primers were tried to get good amplification. RESULTS One hundred and sixteen bands amplified from seventeen primers, were clustered by NTSYS-pc software. Three branches were obtained. Some distinctive primers and bands, which represent certified species or fine breed, were obtained also. CONCLUSION　1) M.officinalis should be divided into three geographic clans instead of two subspecies or varieties, they are, a) typical officinalis, b) typical biloba and c) Middle type. This conclusion agrees with the leaf form and other characters. 2) The genetic difference between “Chuanpo” and “Wenpo” is evident and the difference is in correspondence with the quantities of their chemical constituents. So, the genetic difference is the main reason of the genuineness of Cortex Magnoliae officinalis. 3) These results may be used to establish DNA database for identification of Cortex Magnoliae officinalis.

A liquid chromatography-tandem mass spectrometry (LC-MS/MS) method was developed and validated for the determination of butoconazole in human plasma. Human plasma samples of 0.2 μL were pretreated by a single step protein precipitation procedure and analyzed using a high performance liquid chromatography (HPLC) electrospray tandem mass spectrometer system. The compounds were eluted isocratically on an Inertsil ODS-SP column (100 mm×2.1 mm, 3 μm), ionized using a positive ion atmospheric pressure electrospray ionization source and analyzed using multiple reaction monitoring (MRM) mode. The ion transitions monitored were m/z 412.8→165.1 for butoconazole and m/z 453.4→230.3 for the internal standard. The chromatographic run time was 3.5 min per injection, with retention time of 2.47 min and 2.15 min for butoconazole and repaglinide, respectively. The method was validated to be linear over the range of 20 to 8000 pg/mL (r>0.999) by using a weighted (1/x(2)) quadratic regression. The mean recovery rate was more than 86.7%, and the intra- and inter-day precision of the quality control samples (QCs) was less than 8.3% and the accuracy ranged from 96.0% to 110.2%, which indicated that the quantitative method was reliable and accurate. The method is simple, rapid, and has been applied successfully to a pharmacokinetics study of butoconazole nitrate suppositories in healthy Chinese females.
