Objective To investigate the quality of marriage and sexual function of cervical cancer patients following radical hysterectomy and vaginal extension.Methods Case-control and questionnairebased methods were used in this study.Forty patients of early-stage (Ⅰ b 1 ～ Ⅰ b2) cervical cancer who had undergone vaginal extension following classic radical hysterectomy were included in the observation group,while 40 patients with matching factors and radical hysterectomy only during the same period were included in the control group.The quality of marriage and sexual function were compared with OLSON marriage prolapse and incontinence sexual function questionnaire Shon Fonn (PISQ-12).Results The operation time and postoperative vaginal length in the observation group were higher than those in the control group (P ＜ 0.05 or P ＜ 0.01).The emotional,physical,and total scores during postoperation were lower than those during preoperation (P ＜ 0.01).The emotional,physical,and total scores in the control group were lower than those in the observation group (P ＜ 0.01).The marital satisfaction,husband and wife communication,conflict resolution methods,extracurricular activities and sex scores in the observation group were higher than those in the control group (P ＜ 0.05 or P ＜ 0.01).Conclusions Patients with peritoneovaginoplasty following radical hysterectomy had much longer vagina and less self-perceived short vagina.Vaginal extension following radical hysterectomy does not worsen the pelvic floor symptoms.

OBJECTIVE:To optimize the extraction conditions of volatile oil from Chrysanthemum indicum and the processing techniques of its ?-yclodextrin(?-CD) inclusion compound.METHODS:The extraction conditions of volatile oil from Chrysanthemum indicum was optimized taking soaking time,ultrasonic treatment time,water amount as influencing factors and with the yield of the volatile oil as index.The processing techniques of the ?-yclodextrin (?-CD) inclusion compound was optimized taking the ratio of ?-CD to volatile oil,the time and temperature of the inclusion process as indexes and with the yield of the inclusion compound and the inclusion rate of the volatile oil as indexes. RESULTS:The optimal process for oil extraction was as follows:the soaking time=1.5 h,the ultrasonic treatment time= 40 min,heating time=6 h,water amount=600 mL.The optimal processing conditions for(?-CD) inclusion compound of Chrysanthemum indicum were as follows: the ratio of ?-CD to volatile oil=8∶1,the inclusion time of the compound was 2 hours at 40 ℃.CONCLUSION:High extraction yield of vlatile oil and stable inclusion compound were obtained from the above method.

Most neonatal diabetes mellitus (NDM) is caused by genetic abnormality. Sulfonylurea (SU) has been successfully applied in NDM patients;The pathogenesis of NDM and mechanism of sulfonylurea on molecular level have been illuminated, and recent studies revealed that glycated albumin is a useful glycemic indicator. In this review, the research progress of NDM is summarized.

Objective To investigate the effect of transfusion of allogeneic apoptotic splenocytes on immunological tolerance to pancreatic islets transplantation in rat. Method Recipient SD rats were rendered diabetic mellitus by a single intraperitoneal injection of streptozotocin (STZ). The apoptosis of donor Wistar rat splenocytes was induced by X-irradiation with electron linear accelerator. Pancreatic islets were isolated by intraductal collagenase P, and were purified by Ficoll-400 discontinuous density gradient after culturing for 1-2 days from donor Wistar rat. The diabetic SD rats were randomly divided into 4 groups, and respectively received infusion of Hanks solution, donor normal splenocytes, donor apoptotic splenocytes, and donor necrotic splenocytes via dorsal veins of penis, and then they received pancreatic islets from the same donor rat underneath their renal subcapsular space 7 days later. Mixed lymphocyte reaction (MLR) was used as immunological parameter of transplantation tolerance besides the observation of blood glucose level and allograft survival time. Islet graft failure was defined as the presence of a plasma glucose concentration of at least 11.0mmol/L on 2 successive days. Results The pre-infusion of donor apoptotic splenocytes significantly prolonged the survival time of allograft as shown by the median survival time (MST) of graft of 31days, and the longest survival time of 42 day, and it apparently decreased the rejection response in recipient SD rat in one-way mixed lymphocyte culture. Conclusion Transfusion of donor apoptotic splenocytes could induce immunological tolerance of allogenic islets transplantation in rat.

Objective To determine the planning target volume margins of head and neck cancers treated by image guided radiotherapy (IGRT).Methods 464 sets cone beam computed tomography (CBCT) images before setup correction and 126 sets CBCT images after correction were obtained from 51 head and neck cancer patients treated by IGRT in our department.The systematic and random errors were evaluated by either online or offline correction through registering the CBCT images to the planning CT.The data was divided into 3 groups according to the online correction times.Results The isocenter shift were 0.37 mm±2.37 mm, -0.43 mm±2.30 mm and 0.47 mm±2.65 mm in right-left (RL), anterior-posterior (AP) and superior-inferior (SI) directions respectively before correction, and it reduced to 0.08 mm±0.68 mm, -0.03 mm±0.74 mm and 0.03 mm±0.80 mm when evaluated by 126 sets corrected CBCT images.The planning target volume (PTV) margin from clinical target volume (CTV) before correction were:6.41 mm,6.15 mm and 7.10 mm based on two parameter model, and it reduced to 1.78 mm,1.80 mm and 1.97 mm after correction.The PTV margins were 3.8 mm,3.8 mm,4.0 mm;4.0 mm,4.0 mm,5.0 mm and 5.4 mm,5.2 mm,6.1 mm in RL, AP and SI respectively when online-correction times were more than 15 times, 11-15 times,5-10 times.Conclusions CBCT-based on online correction reduce the PTV margin for head and neck cancers treated by IGRT and ensure more precise dose delivery and less normal tissue complications.

Objective To discuss the influence of respiratory training and prompting effective discharging of sputum for chronic obstructive pulmonary disease (COPD) patients in acute aggravation period. Methods 50 patients were randomized into the intervention group and the control group with 25 cases in each group.The intervention group received respiratory training and prompting effective discharging of sputum while the control was only given routine treatment and nursing.The ratio of first second expiration volume to forced vital capacity, oxygen partial pressure (PaO2),carben dioxide partial pressure (PaCO2) ,blood oxygen saturation (SpO2)and the in-hospital days were compared between the two groups. Results The clinical effect in the intervention group was superior to that of the control group with shorter in-hospital days (P<0.01).Conclusion Better results could be obtained by application of respiratory training and prompting effective discharging of sputum for COPD patients in acute aggravation period.

Objective To discuss the necessity and methods of combined reconstruction of the injured posterior cruciate ligament(PCL)and posterolateral complex(PLC)of the knee. Methods From January 2001 to December 2006,28 patients with injury of both PCL(≥Ⅱ°b)and PLC(＞Ⅱ°)of the knee were treated operatively in our department.Eight patients received arthroscopic PCL reconstruction with single bundle of 5-6 strands of hamstring and conservative treatment of PLC during January 2001 to December 2003.Twenty Datients received arthroscopic PCL reconstruction followed by open operative repair of PLC with median 1/3 femoral biceps tendon and gracilis during January 2002 to December 2006. Results All the patients were followed up for 6 to 24 months postoperatively (mean,15 months).By Lysholm scoring,3 cases obtained good results and 5 poor in the first group,while 19 excellent and 1 good in the second group.The mean Lysholm scores were 47.1±8.2 and 86.7±7.2 respectively(P＜0.05).According to IKDC scale,3 patients(37.5%)in the first group and 19 patients (95.0%)in the second group were graded normal or nearlv normal(t=19.277,P＜0.05). Conclusion Arthroseopic PCL reconstruction with single bundle of 5-6 strands of hamstring plus PLC reconstruction with 1/3 femoral biceps tendon and gracilis is more reliable to restore the stability of the knee than PCL reconstruction only.
