The human ovarian mucinous cystadenocarcinoma (hOMC) cells were co-cultured with antisense oligodeoxynucleotide (antisense ODN), nonsense ODN, and follicle-stimulating hormone (FSH) at different concentrations for the purpose of observing the effects of antisense ODN to FSH receptor (FSHR) on the proliferation and apoptosis of cultured hOMC cells in vitro. The inhibitory rates of growth were measured by using MTT method on the 2nd, 4th, 6th, 8th and 10th days after the interference of antisense ODN, nonsense ODN, and FSH, respectively. The apoptotic rates and the cell cycles were determined by means of flow cytometry, the apoptosis indexes were detected by using TUNEL, and the expression of caspase-3 was measured by using SP immunohistochemistry. Compared with that in the control group, the proliferative activity of hOMC cells was increased obviously in FSH groups (P<0.05 or P<0.01), decreased distinctly in antisense ODN groups (P<0.05 or P<0.01), and unchanged in nonsense ODN groups, respectively. Meanwhile, antisense ODN could significantly antagonize the FSH-promoted cell proliferative activity (P<0.01). Compared with those in the control group, the apoptotic rates and the expression of caspase-3 were dramatically increased in the mid-and high-dose antisense ODN groups (P<0.05 or P<0.01), while the number of cells in G(1)/G(0) phase was significantly decreased and that in S phase distinctly increased (P<0.01). There was no change in nonsense ODN groups (P>0.05). It was suggested that FSH may improve the development of hOMC cells. However, antisense ODN could inhibit proliferative activity and the FSH-promoted proliferative activity in hOMC cells, at the same time, antisense ODN could inhibit hOMC cell growth by inducing apoptosis.

Objective:To compare and analyse the clinical outcome, advantages and disadvantages of submental artery island flap (SAIF) and free anterolateral thigh flap (ALTF) in the repair and reconstruction of tongue after radical surgery of tongue cancer.Methods:From January, 2016 to December, 2018, a total of 40 patients received tongue repair and reconstruction with either SAIF or ALTF after radical resection of tongue cancer. There were 28 males and 12 females, with an average age of 51 years old. Eighteen patients received tongue repair and reconstruction with SAIF and 22 with ALTF. Postoperative follow-up were carried out and the clinical data were collected. Swallowing, speech and softness of the tongue between the 2 repair methods were compared and statistically analysed. P<0.05 indicated a significant statistical difference between 2 groups. Results:All flaps survived. One ALTF had a venous vascular crisis. The flap survived after the removal of thrombus at the anastomotic site. Functional recovery of tongue was analysed after the follow-up of 12-48 months. It was found that there was no significant difference in speech function between the 2 groups (SAIF vs ALTF: 13 vs 15, P=0.206). The swallowing dysfunction in SAIF group was significantly higher than that of the ALTF group (SAIF vs ALTF: 15 vs 7, P=0.014). Moreover, the average time of surgery in SAIF group (3.5 h) was significantly less than that of the ALTF group (6.8 h), which had statistically significance ( P<0.05). Conclusion:The SAIF and ALTF are ideal flaps for repairing the tongue defect caused by tongue cancer surgery. SAIF features a simple surgical procedure and a short time for flap taking. ALTF provides sufficient amount of tissue to cover the scars left by the surgery, reduce donor site complications, and benefit the recovery of swallowing and speech functions.

Objective To investigate the role of interstitial collagenase in the pathogenesis of acute lung injury induced by hyperoxia outside of sealed cages and breath room air,and to study the mechanism of The severity of lung injury.Methods Seventy-two C57BL/6 mice were divided into normal control group,hyperoxia for 24 hours group,hyperoxia for 48 hours and hyperoxia for 72 hours group randomly,18 mice in each group.The hyperoxia group exposedin sealed cages with＞95%oxygen,and the control group were put in the inspiratory room.The expression of interstitial collagenase mRNA and protein in lung tissues was studied by reverse transcript-polymerase chain reaction(RT-PCR)and immunohistochemistry.Results Hyperoxia caused acute lung injury in mice.by The expression of interstitial collagenase mRNA in lung tissues was increased after 24 hours of hyperoxia compared with their control group[0.59±0.11 vs 0.07±0.01,q=3.t5 P＜0.01],the expression was higher at 72 hours of hyperoxia(0.68±0.12,q=3.78 P＜0.01).Immunohistochemistry study showed interstitial collagenase protein was mainly expressed in cytoplasm of airway epithelial cells,while Ⅱ type alveolar epithelial cells mainly and vascular smooth muscle cells in hyperoxia mice.The expression of interstitial collagenase protein in airway epithelium significantly increased at 24 hours of hyperoxia compared with their control group[(28.54±9.60) vs (13.48±4.32)q=2.62 P＜0.05],and the expression level was lower after 48 and 72 hours of hyperoxia(20.32±5.68) vs, (15.24±4.65).Conclusion Hyperoxia cause acute lung injury in mice;interstitial collagenase play an important role in the development of hyperoxia-induced lung injury in mice.

Objective To assess the surgical effectiveness of pelvic endometriosis (EMS) by Laparoscopic. Methods Retrospective analysis was performed in 1272 pelvic EMS patients underwent laparoscopic surgical treatment. All patients were classified into four groups according to the R-AFS,63 patients of Ⅰ stage,44 patients of Ⅱ stage,475 patients of Ⅲ stage and 690 patients of Ⅳ stage. Symptoms of EMS,surgical effect and follow-up outcomes were compared. Results In all stages, there were no significant differences on moderate to severe dysmenorrhea,increase in CA125 and infertility (Ps ＞ 0. 05 ). In the EMS patients combined with AM or/and DIE, the rates of the moderate to severe dysmenorrhea, CA125 increase and infertility were 84.6% (11/13 ) ,92.3 %(12/13) and 53.8% (7/13)in stage Ⅰ ,81.8% (9/11) ,90. 9% ( 10/11 )and 54.5% (6/11) in stage Ⅱ ,84.8%(173/204) ,93. 1% (190/204) and 47.1% (96/204) in stage Ⅲ ,and 81.6% (213/261) ,91.2% (238/261) and 46.4% ( 121/261 ) in stage Ⅳ, respectively. The rates in non-consolidated AM or/and DIE patients were 46.0%(23/50),62.0% (31/50) and 22.0% ( 1 1/50) in stage Ⅰ ,45.5 % ( 15/33 ),54.5% ( 18/33 ) and 18.2% (6/33)in stage Ⅱ ,41.7% ( 113/271 ) ,62.7% ( 165/271 ) and 23.6% (64/271) in stage Ⅲ ,and 47.3% (203/429),60.1% (248/429) and 21.7% (93/429). The difference between the two groups with and without consolidated AM or/and DIE had statistical significance( P ＜ 0.05 or P ＜ 0.01 ). After the treatment, the scores of life's energy, ache,emotion,sleep,social activity and body movement of NHP were significantly superior than those before treatment in all patients ( P ＜ 0.01 ). The surgery time-consuming of Ⅲ and Ⅳ stage patients were (64.5 ± 18.4) min and (61.7 ± 17.1 ) min respectively, which were significantly higher than that of Ⅰ and Ⅱ stage ( ( 31.9 ± 12.3 ) min and (40.3 ± 10. 6) main ] ( t = 20.25, P ＜ 0.01 ). The massive hemorrhages and the internal damage organs occurred in Ⅲ and Ⅳ stage surgery [2.9% and 3.5% ,respectively] ,whereas much less in Ⅰ and Ⅱ stage (0.8% and 1.4% ) ,with no significant difference(P ＞0. 05). After treatment,the rate of symptoms recurrence of Ⅲ and Ⅳ stage patients respectively were 21.4% ,which were higher than that of Ⅰ and Ⅱ stage patients ( 2.3% ) (P ＜ 0.05 )The rate of pregnancy in Ⅲ and Ⅳ stage patients ( 15.4% ) were lower than that of Ⅰ and Ⅱ stage patients (69. 6% ) ( P ＜ 0. 01 ). Conclusions Pelvic EMS decreased the quality of life. EMS patients combined with adenomyosis or/and deep infiltrating EMS have more severe pelvic pain symptoms, less surgical effectiveness and more serious complications. Ⅲ and Ⅳ stage patients are more liable to symptoms recurrence and lower pregnancy rate.

Objective To evaluate the value of Multi-slice spiral CT angiography for spinal cord vessels.Methods 11 adult subjects with suspected of myelopathy were performed with Multi-slice spiral CT angiography,An iodine contrast agent was injected at 3.5 ml/s,for total 100 ml.The parameters were axial 16 slice mode,0.625 mm slice thickness,0.8 s rotation,delay time depending on smartprep (15—25 s), multi-phase scan.The coronal and sagittal MPR and SSD were generated on a workstation compared with spinal digital subtraction angiography (DSA) to analyze normal or abnormal spinal cord vessels.Results Normal findings at spinal CTA and digital subtraction angiography in six adult normal subjects and spinal cord vascular malformations( 1 intradural extramedullary AVF,4 dural AVFs) in five cases,Recognizable intradural vessels corresponding to anterior median (midline) veins and/or anterior spinal arteries were show in six adult normal subjects.Abnormal intradural vessels were detected in all five spinal cord vascular malformation with CT angiography ,in comparison with digital subtraction angiography these vessels were primarily enlarged veins of the coronal venous plexus on the cord surface,radiculomedullary-dural arteries could not be clearly shown in four dural AVF,only one anterior spinal artery was detected in one patient with intradural medullary AVF,which direct shunt between anterior spinal artery and perimedullary vein with tortuous draining vessel.Conclusion Multi-slice CT angiography is able to visualize the normal or abnormal spinal cord vessels.It could be used as a noninvasive method to screen the spinal cord vascular disease.

Background Refractive lens exchange is one of corrective surgeries for high myopic eyes and is concerned in clinic recently. Its clinical value is worthy of consideration. Objective This study was to investigate the efficacy and safety of refractive lens exchange for high myopic eyes. Methods Phacoemulsification and intraocular lens implantation was performed on 124 eyes of 65 patients with high myopia. The mean age of these patients was 51. 4±8. 57 years old,and the preoperative corrected visual acuity was 4. 11±0. 51. The mean spherical equivalent was ( -20. 17±5. 34) D. The mean axial length was (31. 33±2. 08) mm and intraocular lens power 2. 88 D. The follow-up time was 31 months. The uncorrective visual acuity, best corrective visual acuity, the spherical equivalent lens and complications were observed after operation. Written informed consent was obtained prior to the surgery. Results The uncorrective visual acuity improved after the operation in all the eyes. The uncorrective visual acuity was ≥0.5 in 15 eyes(12% ). The best corrected visual acuity improved in 114 eyes (92% ) following the surgery and that of 64 eyes (51. 6% ) was 2s 0. 5. The mean postoperative spherical equivalent was ( -2. 57 ± 1. 76 ) D in the entire follow-up duration. Posterior capsular opacification was found in 58 eyes (46. 7% ) and received laser capsulotomy. Retinal detachment occurred in 4 eyes throughout the follow-up period. Conclusion Refractive lens exchange is an effective and safe method for high myopic eyes. But preoperative fundus examination and long-term postoperative follow-up should be carried out to prevent the complications.

Objective To investigate the effect of clinical pathway on inpatients for rehabilitation. Methods The hospital expense, the ex-pense for medicine and length of stay in hospital were compared in patients with cerebral hemorrhage, cerebral infarction, spinal cord injury and spastic cerebral palsy before (January 1st, 2012 to April 30th, 2013) and after (May 1st, 2013 to December 31st, 2015) clinical pathway implementation, 50 inpatients for each disease, totally 200 patients. Results The length of stay in hospital reduced after of clinical pathway implementation, in all the diseases (t>5.226, P<0.001), with the decrease of hospital expense for cerebral infarction (t=3.327, P<0.001). There was no significant increase in any expense in the disease (t<1.777, P>0.05). Conclusion The implementation of rehabilitation clinical pathway can reduce the length of stay in hospital for the patients rehabilitation in hospital, without increasing their cost.
