Chinese Journal of Postgraduates of Medicine 2011;34(35):23-25
Objective To study the microscopic anatomy of the facial nerve trunk,and provide some important morphometric data about facial-hypoglossal nerve anastomosis.Methods The cervical course and adjacent structures of the hypoglossal nerve were observed on 5 adult cadavers;the facial nerve trunk (from stem hole to fork of breast of facial nerve) and the distance from mastoidale to stem hole and sectional area of hypoglossal nerve frunk were measured.The operation was imitate on 5 cadavers.Results The length of the facial nerve trunk was ( 15.71 ± 1.97) mm,its diameter upon its emergence from the foramen was( 2.57 ± 0.60) mm.The distance between the bifurcation and the mastoidale was ( 18.20 ± 4.40)mm.The distance between the bifurcation and the mandibular angle was (39.91 ± 8.38) mm.The distance between the mastoidale and the stylomastoid foramen was (17.91 ±2.68) mm.The facial nerve trunk was monofascicular with across-sectional area of 4.6-5.7 (5.1 ± 0.2) mm2.The number of the fasciculus and the cross-sectional areas of the nerve trunk and the fasciculus were 1-4 ( 1.6 ± 0.8) bind,6.8-8.0 (7.5 ± 0.7)mm2,and 4.1-5.5 (4.7 ±0.6) mm2,rospectively,at the distance their number were 1-5 (3.6 ±0.5) bind,4.9-6.1 (5.6 ± 0.5) mm2.Conclusion Hypoglossal nerve and facial nerve anastomosis and facial-hypoglossal nerve anastomosis into the graft could be used in patients,and hypoglossal nerve function can be achieved to minimize the effect of the collapse.

Chinese Journal of Rehabilitation Theory and Practice 2006;12(8):712-713
ObjectiveTo observe the effect of Indapamide on the rehabilitation of cardiac function in patients with primary hypertension disease.Methods56 patients with primary hypertension disease were randomly divided into the Indapamide group and Hydrochlorothiazide group with 28 cases in each group, and treated with Indapamide and Hydrochlorothiazide respectively assisted with conventional non-drug treatment such as dietetic and weight control. The cardiac functions of patients in two groups were examined with echocardiography before and two months after treatment.ResultsAfter treatment, the left ventricular ejection fraction (LVEF) raised and relative wall thickness (RWT) declined in patients of two groups, but the effect of the Indapamide group was better than that of the Hydrochlorothiazide group ( P<0.05).ConclusionThe effect of Indapamide on cardiac function and structure is better than Hydrochlorothiazide.

Objectives To evaluate the therapeutic effect of argon laser photocoagulation combined with intravitreous injection of triamcinolone acetonide (TA) on ischemic central retinal vein occlusion (CRVO). Methods Argon laser photocoagulation combined with intravitreous injection of TA was performed on 17 patients (17 eyes) with CRVO between December 2003 and July 2004. Results During the follow-up of 4-10 months, the visual acuity improved in 16 patients, including alleviated or even disappeared cystoid macular edema (CME) in 5, and recurred macular edema in 5 with decreased visual acuity after 3 months. Six patients had increased ocular pressure after intra-ocular injection which alleviated after treated suitably. No neovascularization in angle or secondary neovascular glaucoma was found. Conclusion [WTBZ]Argon laser photocoagulation combined with intravitreous injection of TA may improve the visual acuity and reduce complications in ischemic CRVO, though macular edema may recur in some cases.

Objective To screen the target genes that contribute to cisplatin resistance in ovarian cancer treatment. Methods Gene expression and methylation profiles of ovarian cancer cells that were sensitive or resistant to cisplatin with accession number GSE15709 were downloaded from GEO database. Differential expressed and methylated genes were identi?fied through associating packages in R. DAVID database to screen the enriched GO terms and pathways of the different ex?pressed genes between A2780 and A2780/DDP. Gene Set Enrichment Analysis (GSEA) of different gene was performed against DAVID database. Genes that exhibited difference in both expression and methylation profiles between the two types of ovarian cancer cells as well as genes that present contradictory profile between expression and methylation were verified via qRT-PCR. Results We found 416 different expressed genes and 281 methylated genes between the two types of ovari?an cancer cells respectively. These differential genes were rich in pathways of cell cycle, DNA replication, nucleus division , p53 signaling , and negative regulation of protein modification process etc. Four genes demonstrated contradictory profile be?tween expression and methylation in the two types of ovarian cancer cells and were verified by qRT-PCR. Conclusion Combination of bioinformatics and molecular biology is useful in the identification of target genes that contribute to resis?tance of cisplatin in ovarian cancer treatment and further reveal molecular mechanism behind it.

Corneal refractive surgery has been the major solution for the correction of ametropia.With the standardization of preoperative examination,intraoperative procedure and perioperative drugs,corneal refractive surgery has become much safer.Meanwhile,patients can get not only good visual acuity,but also favorable visual quality.However,the patient satisfaction has not been improved dramatically with the enhance of effectiveness and safety after surgery.Increase of the satisfaction degree to corneal refractive surgery is related to multiple factors such as experienced and highly skilled operation,operative safety,lessening operative complication,good postoperative visual and life quality of patients.Comprehensively analyzing existing problems in corneal refractive surgery in China and further obtain satisfaction of patient will be of an important significance for the healthy development of laser corneal refractive surgery.
9.Laparoscopic Myomectomy for Hysteromyoma in 82 Patients with the Uterus Larger than 14-week Gestational Size
Chinese Journal of Minimally Invasive Surgery 2001;0(03):-
Objective To analyze the feasibility, safety, and technique of laparoscopic myomectomy in patients with large hysteromyoma. Methods A total of 82 hysteromyoma patients with the uterus larger than 14-week gestational size were treated by laparoscopic myomectomy. The outcome of the operation were compared with that in 182 hysteromyoma cases with the uterus smaller than 14-week gestational size. Results In the 82 patients with the uterus larger than 14-week gestational size, 77 were treated successfully by laparoscopy, in which pneumoperitoneum was used in 68 cases and gasless laparoscopy in the other 9. One of the cases converted to open surgery, and small abdominal incision was made in 4 patients. Compared with the patients with the uterus smaller than 14-week gestational size, the 77 patients who had been successfully by laparoscopy had longer operation time [(157.6?89.7) min vs (35.3?26.2) min, t=16.926, P=0.000] and more blood loss [(218.0?108.2)ml vs (108.5?67.5)ml,t=9.904,P=0.000]. Conclusions Myomectomy can be performed under a laparoscope for patients with the uterus larger than 14-week gestational size. Highly skilled technique is important for the surgery.!Gasless laparoscopy is applicable to myomectomy for patients with the uterus smaller than 16-week gestational size.

Objective To study the effects of tri-ortho-cresyl phosphate(TOCP) on mitochondrial membrane permeability in hen's nerve tissues and investigate the mechanism of the organophosphorus ester-induced delayed neurotoxicity(OPIDN).Methods Adult Roman hens were randomly divided into four groups,including three treated groups and one control group(24 in each group).The hens in the experimental groups were treated with TOCP by gavage at the single dosages of 185,375 and 750 mg/kg respectively.TOCP was dissolved in corn oil and administered at 0.65 ml/kg.The control hens received an equivalent volume of corn oil by gavage.The hens were sacrificed on the 1st,5th,15th and 21st day after treatment and the cerebrum,cerebellum,spinal cord were dissected and homogenized in ice bath.The mitochondria in these nerve tissues were extracted to determine the changes of the membrane permeability and membrane potential.Results Compared with the control group,no significant increase of the mitochondrial membrane permeability in the cerebrum was observed in treated groups.In the cerebellum,the membrane permeability in the 185 mg/kg group had no significant changes,while in the 375 and 750 mg/kg groups it increased significantly on the 1st and 5th day after TOCP treatment(P
