Objective To assess patient ’ s fallopian tube function after laparoscopic salpingotomy for tubal ectopic pregnancy.Methods We observed the degree of pelvic adhesion and previous tubal patency by laparoscopic secondary exploration. The fallopian tube function were evaluated in 24 cases ( 26 fallopian tubes ) which had experienced laparoscopic salpingotomy. Results There were 4 cases of severe adhesions (16.7%), 4 cases of moderate adhesions (16.7%), 5 cases of mild adhesions (20.8%), and 11 cases of minor adhesions (45.8%).The status of fallopian tubes:tubal rapture and tissue absence were seen in 11 oviducts (42.3%), intact but obviously shortened oviduct with distal hydrops was seen in 11 oviducts (42.3%), and normal oviduct was recorded in 4 oviducts (15.4%).The methylene blue flow test was performed in the 26 tubes, showing 23 (88.5%) occluded and 3(11.5%) patent. Conclusions The fallopian tubes have incomplete shapes after laparoscopic tubal fenestration for ectopic pregnancy in most patients.We confirm that laparoscopic salpingotomy can not preserve the fertility effectively.

Objective To investigate the receptor involved in the TNF?induced HO-1 expression and the related signal transduction mechanisms in the brain microvessel endothelial cells.Methods TNF? receptor 1(TNFR1)knockout murine brain microvessel endothelial cells(BMVECs)in vitro culture were stimulated respectively by TNF?(5ng/ml).After 24 hours,the level of HO-1 gene mRNA were detected by semi-quantitative RT-PCR,the effect of TNF?on JNK 、ERK or transcription factor AP-1 were analyzed by Western blot,while ERK inhibitor(PD98059)or JNK inhibitor(SP600125)were used.Results Exposure of wild-type BMVECs and TNFR1(p55)knockout BMVECs [BVEC/TNF-RI(-/-)] to TNF?(5ng/ml,24 h)caused a marked increase in HO-1 mRNA expression.Furthermore,TNF? stimulation also lead to the activation of JNK,ERK and the transcription factor AP-1 in the BVEC/TNF-RI(-/-),However,incubation with the JNK inhibitor SP600125 but not the ERK inhibitor PD98095 attenuated the TNF?-induction of HO-1 in the BVEC/TNF-RI(-/-).Conclusions TNFR2 and JNK activation but not TNFR1 might be essential for mediating the TNF?-induction of the HO-1 in the endothelial cells.

Objective To observe the structural abnormalities of the painful shoulder in patients soon after stroke by M RI,and to identify the possible causes of post-stroke shoulder pain (PSSP).Methods Patients with hemiplegia following their first cerebrovascular accident were divided into 2 groups:PSSP group (32 patients) and post-stroke no shoulder pain (PSNSP) group (20 patients).Physical findings of affected shoulder and MRI findings of both affected and unaffected shoulders were evaluated.Results Shoulder subluxation was significantly more frequent in PSSP group than in PSNSP group (53％ vs 15％,P ＜0.05).In PSSP group,the incidence rate of rotator cuff injury,subacromial-subdeltoid bursa effusion,glenohumeral joint effusion,effusion of long head of biceps tendon was higher in affected side than that in unaffected side(63％ vs 13％,53％ vs 13％,75％ vs 31％,41％ vs 13％,respectively).In PSNSP group,the incidence rate of glenohumeral joint effusion was higher in affected side than that in unaffected side (70％ vs 17％).But compared with no pain hemiplegic shoulder,only rotator cuff injury and subacromial-subdeltoid bursa effusion were significantly higher in PSSP patients (63％ vs15％,53％ vs 25％,respectively),and there was significant difference between the two groups (P ＜0.05).Conclusion Rotator cuff injury was found to be a possible cause of PSSP.

Objective To investigate the current formaldehyde pollution levels in the decoration materials in Beijing. Methods Some of the detecting samples were collectted selectively by sampling and some were provided by the manufacturers voluntarily. The contents of formaldehyde in the samples were determined according to the National Standard Detecting Method for the threshold of harmful substances in decoration materials. Results The emission levels of formaldehyde in 15 of 27 man-made board samples were higher than 1.5 mg/L and the rate exceeding the national standard was 56%. The formaldehyde emission level from 1 of the 4 wall-dope samples was higher than the national standard. In 7 gooey samples,the content of formaldehyde in 1 sample was higher than the national standard. The detecting results of 3 wallpaper samples were all accorded with the national hygienic standard. Conclusion The results of this investigation indicated that some problems did exist in the current decoration materials made in our country. The relatively serious problem among them was that the emission level of formaldehyde from the man-made boards and its related products was much higher than the national standard.

Objective The purpose of this study was to investigate the effect of isoflurane on baroreflex sensitivity ( BRS ) during induced hypotension and to illucidate the mechanism of isoflurane-induced hypotension. Methods Fifteen female ASA I or II patients aged 13-16 yrs undergoing scoliosis surgery were studied. The patients were unpremedicated. Radial artery and internal jugular vein were cannulated for BP and CVP monitoring. EGG, BP and SpO2 were continuously monitored before and during anesthesia. Anesthesia was induced with midazolam 0.04 mg? kg-1 , fentanyl 2 ?g? kg-1 and propofol 2 mg? kg-1 . Tracheal intubation was facilitated with rocuronium 1 mg?kg-1 . Anesthesia was maintained with isoflurane inhalation and fentanyl infusion (0.4?g?kg-1?h-1). Nitroglycerin (NTG) was infused at 1 ?g?kg-1 ?min-1 at the beginning of surgery to control MAP at 55-65 mm Hg and esmolol 20 mg was given i. v. to control HR 0.8. BRS was measured before induction of anesthesia (T1), immediately after intubation (T2), when end-tidal concentration of isoflurane reached 0.7% (T3 , supine) (T4 , prone), when end-tidal concentration of isoflurane reached 1.3% (T5) , at 30 min after NTG infusion and esmolal bolus injection were stopped (T6) when end-tidal concentration of isoflurane was decreased to 0.7 % (prone, T7 ) and immediately after the patients were turned supine (T8 ) . Results When end-tidal isoflurane concentration reached 1.6%, the desired level of hypotension could be maintained without NTG infusion and esmolol injection. BRS gradually decreased with increasing end-tidal isoflurane concentration. BRS was the lowest at 30 min after termination of NTG infusion and esmolol bolus injection. Conclusion Isoflurane depresses BRS and BRS depression may be involved in the mechanism of isoflurane-induced hypotension.
