OBJECTIVETo observe the effect of Kuntai Capsule (KC) on the number of retrieved oocytes, the quality of high-quality oocytes and embryos in in vitro fertilization of poor ovarian response (POR) patients.

METHODSTotally 70 POR patients preparing for in vitro fertilization-embryo transfer (IVF-ET) were randomly assigned to the observation group and the control group, 35 cases in each group. KC was administered to patients in the observation group in the preparation cycle (i.e., three menstrual cycles before IVF-ET) and during the superovulation process. Those in the control group took placebo during this period. Before and after medication the improvement of Shen yin deficiency syndrome (SYDS) was observed in the two groups. The basal follicle-stimulating hormone (bFSH), luteinizing hormone (LH), estradiol (E2), anti-Mullerian hormone (AMH), the ratio of FSH to LH, and antral follicle count (AFC) were observed. Besides, the E2 level of a single ovum on the day of HCG injection, the number of retrieved oocytes, the high-quality oocyte rate, and the high-quality embryos were observed.

RESULTSCompared with the control group, the SYDS, decreased bFSH and LH levels, increased ACF numbers, the E2 level of a single ovum on the day of HCG injection, the number of retrieved oocytes, high-quality oocytes, and high-quality embryos were superior in the observation group (P < 0.05). There was no statistical difference in the decreased FSH/LH level (P > 0.05). E2 and AMH increased after medication of KC in the observation group, while they decreased after administration of placebos in the control group. There was statistical difference in the post-pre treatment difference of E2 and AMH between the two groups (P < 0.05).

CONCLUSIONKC could increase the number of retrieved oocytes, and elevate the quality of occytes and embryos in the IVF-ET.

Objective To investigate the clinical value of endometrial receptivity detected by transvaginal color Doppler flow imaging(TV-CDFI) in patients treated with ovulation induction. Methods Fifty-three anovulation patients were divided into two groups at random, 28 cases (67 cycles) in the combined group treated with traditional Chinese medicine and human menopausal gonadotropin(HMG), and 25 cases(66 cycles) in the HMG group were treated with HMG alone. The endometrial thickness, patterns and the parameters of the uterine artery blood flow were detected by TV-CDFI. Results There were significant differences between the conception and non-conception group, and between the combined group and the HMG group in endometrial thickness, patterns and the parameters of the uterne artery blood flow on the day of HCG injection(P

Objective To investigate the effect of esmolol pretreatment on propofol injection pain..Methods Ninety patients undergoing breast cancer surgery under general anesthesia were ran-domly assigned into three groups (n=30 each).Group E were pretreated with 5 mg/ml(total 2 ml)es-molol group L with 20 mg/ml (total 2 ml)lidocaine and group N with 2 ml normal saline.After one minute,each group was administrated propofol intravenouly.The pain and hemodynamic data were re-corded.Results Compared with group N,propofol injection pain degree decreased obviously in groups E and L (P <0.05).propofol injection pain occurred in 25 (83.3%)in group N,was signifi-cantly higher than that of 12 (40.0%)in group E and 14 (46.7%)in group L (P <0.05),propofol injection pain had no significant difference between groups E and L.Compared with T1 ,SBP,DBP decreased in groups E and L at T2 ,SBP decreased in group N at T2 significantly (P <0.05).Com-pared with T2 ,DBP was significantly higher at T3 in group E (P <0.05).Conclusion Pretreatment with low dose esmolol was effective in attenuating pain during propofol injection.

Objective: To identify the mutation of human ether-a-go-go-related gene (hERG) and analyze the clinical characteristics of a Chinese family with long ST syndrome (LQTS). Methods: The electrocardiogram and DNA samples were obtained from a Chinese LQTS family of 26 members. Genotype was performed with polymorphic short tandem repeat (STR) markers at the known LQT1, LQT2, and LQT3 loci. SSCP analysis was used to find aberrant conformers. hERG mutation was confirmed by cloning and sequencing. Results: Three gene carriers were linked to chromosome 7q35-36, where the potassium channel gene hERG was encoded. A 19-base pair deletion was identified. The mutation was located at nucleotide position 1619-1637 between transmembrane domains S4 and S5. Furthermore, A1692G polymorphism was found both in the normal control and patients. Conclusion: A novel 19 bp deletion mutation of hERG is identified in a Chinese family. All gene carriers are demonstrated to be typical LQT2 ECG phenotype.

Objective To investigate the effect of hypercapnia on cerebral oxygen metabolism under propofol anesthesia during one-lung ventilation (OLV) in patients.Methods Forty ASA physical status [or Ⅱ patients,aged 53-63 yr,scheduled for elective lobectomy performed via video-assisted thoracoscope,were enrolled in the study.Anesthesia was induced with iv injection of midazolam,fentanyl and vecuronium and target-controlled infusion of propofol and maintained with target-controlled infusion of propofol and intermittent iv boluses of fentanyl and vecuronium.BIS value was maintained at 40-60 during surgery.At 15 min of OLV,hypercapnia was performed and PaCO2 was maintained at 50-55 mm Hg lasting for 15 min,and then respiratory rate was adjusted to maintain PaCO2 at 40-45 mm Hg.Immediately before OLV (T0),at 15 min of OLV and hypercapnia (T1,2),and at 15 min after the end of hypercapnia (T3),arterial and jugular bulb venous blood samples were obtained for determination of arterial partial pressure of oxygen (PaO2),arterial oxygen saturation (SaO2),jugular bulb venous oxygen partial pressure (PjO2) and hemoglobin saturation (SjO2).The arterial to venous oxygen content difference (Da-jO2) and cerebral extraction rate of oxygen (CERO2) were calculated.Results SaO2 and PaO2 at T1-3,SjO2 and PjO2 at T1 and T3 and Da-jO2 at T2 were significantly lower and CERO2 at T1 and T3 was higher than those at T0 (P ＜ 0.05).SjO2 and PjO2 were significantly increased and Da-jO2 and CERO2 were significantly decreased at T2(P ＜0.05) and no significant changes were found in the parameters of cerebral oxygen metabolism at T3 as compared with those at T1 (P ＞ 0.05).Conclusion Hypercapnia can improve cerebral oxygen metabolism under propofol anesthesia during OLV in patients.

Objective To determine the optimum dose of oxycodone inhibiting responses to tracheal intubation with a double-lumen endobronchial tube in patients undergoing one-lung ventilation (OLV).Methods Sixty adult patients aged 55-64 yr, weighing 60-80 kg, with American Society of Anesthesiologists physical status Ⅰ or Ⅱ, scheduled for elective thoracic surgery requiring OLV, were randomly divided into 3 different doses of oxycodone groups (O1-3 groups, n =20 each).Anesthesia was induced with iv midazolam 0.05 mg/kg, oxycodone 0.30, 0.35 and 0.40 mg/kg (O1.3 groups, respectively) , propofol 1.5 mg/kg and rocuronium 0.9 mg/kg.The patients were tracheally intubated using a double-lumen endobronchial tube and mechanically ventilated.Before anesthesia induction (T0) , immediately before and after intubation (T1,2) , and 1 and 5 min after intubation (T3.4) , arterial blood samples were taken to determine the concentrations of serum norepinephrine (NE) and epinephrine (E) using high-performance liquid chromatography.The occurrence of bucking, body movement, hypertension, and tachycardia were observed.Results The concentrations of serum NE and E were significantly increased at T2,3 than at T1 in group O1 (P＜0.05).Compared with group O1 , the concentrations of serum NE and E were significantly decreased at T2,3 , and the incidence of bucking, body movement, hypertension, and tachycardia was decreased in O2 and O3 groups (P＜0.05).There was no significant difference in the parameters mentioned above between O2 and O3 groups (P ＞ 0.05).Conclusion The optimum dose of oxycodone inhibiting responses to tracheal intubation with a double-lumen endobronchial tube is 0.35 mg/kg in patients undergoing OLV.

Objective To summerize the clinical experience of 23 cases of carotid cavernous fistula(CCF) and discuss the treatment strategy. Methods Retrospectively analyzed 23 patients(11 males and 12 females) of CCF,including 14 patients with Barrow type A,1 with type B,1 with type C and 7 with type D. Results Vascular approach for embolization was undertaken in 20 cases by transarterial access and 2 via venous route while 1 case was given up. Among them,9 cases obtained complete occlusion by simple balloon embolization and 5 were treated by direct occlusion of internal carotid artery. Another 5 cases used NBCA glue for the occlusion,1 case was embolized by gelatin-sponge particulates combined with compression of carotid artery,2 cases were treated by coil embolization of cavernous sinus and 1 case was only managed by carotid compression maneuver. We achieved satisfactory clinical results with 21 patients cured and 2 patients improved. Conclusion Complexity and refractory are the characteristic of CCF,and endovascular treatment should be the major choice of treatment. (J Intervent Radiol,2006,15: 323-326)

ObjectiveTo explore the role of autofluorescence bronchoscopy in lung cancer operation and the meaning of choice lung cancer operation mode.MethodsTo retrospectively analyze 32 non-small cell lung cancer patients.Before lung cancer operation,white light bronchoscopy (WLB) and autofluorescence bronchoscopy (AFB) had been done routinely.Compared the different invasive tumor conditions by WLB and AFB,operation modes were decided by the edge of the tumor which were proved by biopsy pathology.ResultsIn 32 cases,19 cases underwent pulmonary lobectomy.One case underwent carinal resection and reconstruction.8 cases underwent sleeve lobectomy.4 cases underwent other therapy because of tumor airway metastasis.In 8 cases which underwent sleeve lobectomy,3 ca ses were found by WLB and AFB together,5 cases were found only by AFB.In 4 cases who had no operation chance,2 cases were found by WLB and AFB together,2 cases were only by AFB.The sensitivity for the detection of bronchial premalignant lesions was extremelyhigher withthe addition of AFB than WLBalone ( P ＜ 0.05 ).ConclusionAutofluorescence bronchoscopy is a safe and efficient technique which could improve the sensitivity of diagnosis in lung cancer than WLB.It is important to select operation mode.

OBJECTIVETo study 3 different strategies of urine drainage following hypospadias urethroplasty, the clinical nursing in their application, and their effects.

METHODSWe retrospectively analyzed the clinical data of 595 cases of hypospadias treated by urethroplasty. After surgery, 133 of the patients underwent urine drainage by suprapubic cystostomy (group A), 202 by urethral stent- tube indwelling (group B), and 260 by early initiative micturition with the urethral stent-tube (group C). All the patients received routine postoperative nursing care required for hypospadias repair.

RESULTSOperations were successfully completed in all the cases. Group C showed a remarkably shorter hospital stay and lower incidence rates of urinary fistula and urethral stricture than groups A and B (P<0.05), but there were no significant differences in the three indexes between A and B (P<0.05).

CONCLUSIONFor urine drainage following hypospadias repair, early initiative micturition with the urethral stent-tube can significantly reduce postoperative complications, decrease difficulties and workload of nursing care, and shorten the hospital stay of the patient.
