Chongqing Medicine 2015;(30):4229-4231
Objective To observe the change of protein levels of large conductance calcium activated potassium channel (BK‐Ca) in placental arteriole smooth muscle cells from hypertensive disorder complicating pregnancy and discuss its role .Methods Western blot analysis was used to examine protein expression of α subunit andβ1 subunit of BKCa channels in placental arteriole smooth muscle cells from hypertensive disorder complicating pregnancy .Results The relative protein expression level of α‐subunit in the HDCP group was 1 .001 2 ± 0 .169 8(n=15) ,and the NT group was 1 .028 2 ± 0 .180 6 (n=15) .There was no significant differences between the two groups (P> 0 .05);the relative protein expression level of β1 subunit in the HDCP group was 0 .418 1 ± 0 .080 8 (n=15) ,and the NT group was 1 .616 8 ± 0 .012 6 (n=15) ,theβ1‐subunit protein expression levels of HDCP group were significantly lower (P<0 .05) .Conclusion The protein expression ofβ1‐subunit ,but notα‐subunit ,was reduced in pla‐cental arteriole smooth muscle cells from hypertensive disorder complicating pregnancy .Therefore ,BKCa channel activity may have been involved in hypertensive disorder complicating pregnancy ;and the abnormal expression ofβ1 subunit maybe an important basis in hypertensive disorder complicating pregnancy .
2.Study and management for issues about patients with lupus nephritis after pregnancy
Chinese Journal of Practical Internal Medicine 2001;0(06):-
Systemic lupus erythematosus(SLE)is an autoimmune disease that affects primarily women,commonly in their reproductive years but does not influence fertility.More recent prospective studies indicate that pregnancy is safe for the majority of mothers if it is planned when SLE is quiescent.In pregnant women with lupus nephritis,the outcome of the fetal and maternal is strongly correlated with lupus activity,kidney function and the presence of aPL at the time of conception.To prevent renal complications,prednisone is given after conception,and reinforcement for a few days before the estimated delivery and for a week after delivery or miscarriage with rapid tapering to maintenance levels may be suggested.Treatment of flares includes corticosteroids,hydroxychloroquine,azothioprine and cyclosporin A.Blood pressure is controlled with methyldopa,labetalol nifedipine or hydralazine.

Objective To review published literatures comparing the safety and effectiveness of retroperitoneal laparoscopic partial nephrectomy (RLPN) with transperitoneal laparoscopic partial nephrectomy (TLPN) and provide reference for clinical work. Methods The search strategy was performed to identify relevant papers from the Cochrane Central Register of Controlled Trials, EMBASE, MEDLINE, Google Scholar, China Hospital Knowledge Database, Wangfang Chinese Periodical Database, and VIP Chinese Periodical Database. All papers comparing RLPN with TLPN were included from 2000 to 2015.Two to three reviewers independently screened, evaluated, and extracted the included papers. A Meta-analysis was executed by using Review Manager 5.3 software. The interesting outcomes were tumor size, operating time, estimated blood loss, warm ischaemia time, length of hospital stay, positive margin rate, open conversion rate, overall complication rate, and recurrence rate. Results The literature search obtained 378 papers, then 10 of them were ultimately met the inclusion criteria and included in the systematic review. Finally, 6 of the 10 papers were included in the Meta-analysis. RLPN had significantly less operating time [P= 0.01, mean difference (MD)=-33.68, 95% confidence interval (CI) within (-60.35,-7.01)] and shorter length of hospital stay [P< 0.0001,MD=-1.47, 95%CI within (-2.18,-0.76)] than TLPN. Significant differences were not found between RLPN and TLPN in other outcomes. Conclusions RLPN may be equally safe and be faster than TLPN. Each center can choose a modality according to your own operating habits and experience.

The mode of long-chain alkane uptake by Pseudomonas aeruginosa (CGMCC 1.1785) was studied. P. aeruginosa 1.1785 is capable of using solid long-chain alkane as sole carbon source and producing surface active compound as metabolite. The mass transfer limitation in uptake of alkane was confirmed from the observation that interfacial area of eicosane with water dominates the growth rate of this strain. The enhancement of eicosane uptake by rhamnolipid was mainly caused by increase of interfacial area, since the pseudosolubilized alkane can not support the growth of P. aeruginosa 1.1785. Cell surface hydrophobicity was increased dramatically at the initial phase of growth and followed by a gradual decrease, which indicates that different modes are employed by P. aeruginosa 1.1785 at different growth phase. Therefore, the surfactant mediated mode can be negligible in the uptake process, while the directly attachment mode may not work throughout the growth of P. aeruginosa 1.1785. We proposed a novel uptake mode, in which the chemotaxis of this strain plays an important role.

Objective To explore the tubal patency after laparoscopic salpingotomy and embryo removal for tubal ectopic pregnancy. Methods A retrospective analysis was made on 28 patients receiving laparoscopic salpingotomy at other hospitals from September 2013 to September 2014.Within their 6 postoperative months, these patients were given hysterosalpingography in this gynecological minimally invasive center to evaluate the tubal patency. Results There were 6 cases of ipsilateral tubal patency (21.4%) and 22 cases of tubal obstruction or dropsy (78.6%), while 19 cases of contralateral tubal patency (67.9%) and 9 cases of tubal obstruction or dropsy (32.1%).Bilateral tubal embryo removal was carried out in 3 cases, with hysterosalpingography showing bilateral tubal obstruction in 2 cases and bilateral tubal dropsy in 1 case.One patient had ipsilateral tubal obstruction after tubal embryo patency and developed contralateral tubal patency after conservative treatment.Follow-up of the 28 cases for 6-15 months showed 4 cases of intrauterine pregnancy, 4 cases of examination of ovulation, 7 cases of preparation of assisted reproduction, 3 cases of laparoscopic salpingoplasty 1-2 months after hysterosalpingography, 1 case of endocrine regulation monitoring ovulation, 1 case of abnormal uterine bleeding 13 months later ( hysteroscopic examination showed endometritis and diagnostic curettage found proliferative phase endometrium that consistent with the menstrual cycle), and 8 cases without further treatment. Conclusion Laparoscopic salpingotomy for tubal ectopic pregnancy does not improve patient’ s tubal patency.
9.An experimental study on the central effects of procaine.
Chinese Journal of Anesthesiology 1994;0(04):-
The analgesic, sedative and convulsive effects of procaine were determined by animal experiments. The analgesic ED50 of procain were 21.7mg/kg or 52.8ug/ each (iv or icv, hot plate) and 29.2mg/kg or 52.2ug/ each (iv or icv,electral stimulation) in mice.Procaine In subthreshold dose had additive hypnotic effect of phenobarbital in mice and rabbits, but could not de crease spontaneous activity in mice.The convulsive ED50 of procaine were 13.5mg/kg (iv) or 2.4mg/each (icv) in rabbits.There was no influence on the righting reflex in all the experiment animals when iv or icv procaine was given alone.These results suggest that the analgesic and sedative effects of procaine are weak, but may be potentiated when administered concomitantly With other potent drugs.
10.Effects of sodium oxybate on pharmacodynamics of ketamine in animals
Chinese Journal of Anesthesiology 1996;0(08):-
The interaction between sodium oxybate and ketamine were studied in conscious animals. Sodium oxybate increased the LD_(50) of ketamine, increased the incidence of sleep caused by ke tamine and prolonged the sleep duration and potentiated analgesic action of ketamine. Sodium Oxybate didn't effect the respiratory and circulatory function in rabbits. The results showed sodium oxybate po tentiated the anesthetic action of ketamine and reduced the side effect of ketamine. So It is suggested that sodium oxybate has the anesthetic synergism with ketamine in animals.
