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 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.

OBJECTIVE:To investigate the risk,advantages and disadvantages and countermeasures of new drugs,generic drugs and imported drugs in different transfer opportunities,and to provide basis for improvement of development strategy for phar-maceutical enterprises. METHODS:The analysis was done in accordance with relevant regulations on transferable projects in the process of applying for registrations of new drugs,generic drugs and imported drugs. The transfer period and risk were explored and countermeasures were put forward. RESULTS & CONCLUSIONS:Transferable projects included intellectual property rights (patents,patent application,technical secrets,application information,non-disclosed data,etc.)and ownership rights(clinical tri-al approvals,new drug certificates,drug approval number,pharmaceutical product registration certificates,imported product regis-tration certificates,etc.)in the process of applying for registrations. There are 4 opportunities for drug technology transfer,opportu-nity 1 is before applying clinical trial approvals after the completion of non-clinical research such as pharmacology,toxicology;op-portunity 2 is ahead of clinical trial after the acquirement of clinical trial approvals;opportunity 3 is new drug technology transfer;opportunity 4 is production technology transfer. The new drugs have 4 transfer opportunities,generic drugs and imported drugs can transfer in opportunity 1,2,4. Different transfer opportunities present different risks and profits. The risk gradually decreases with the further promotion of drug registration process,while the innovation decreases at the same time. Pharmaceutical enterprises should combine with the policy,market and their own features to select a suitable transfer period.

Objective · To explore the change of metabolomic profiling after erlotinib (anepithelial growth factor receptor tyrosine kinase inhibitor)resistance of lung adenocarcinoma cells (PC9-ER), and find the differential metabolome associated witherlotinib resistance. Methods · Metabolic profiling of PC9-ER cells and homologous parent PC9 cells was acquired by the ultraperformance liquid chromatography tandem quadrupole time-of-flight mass spectrometry (UPLC-QTOF/MS). The data were analyzed by multi-dimensional statistical methods, such as partial least squares projection to latent structures-discriminant analysis (PLS-DA), to select and identify differential metabolites associated with erlotinib resistance. Results · A total of 14 differential metabolites were identified in PC9-ER cells. Seven up-regulated metabolites included N-acetylspermidine, phosphatidylethanolamine, AMP, pantothenic acid,proline, glutamate, and histidine, while seven down-regulated metabolites included citrulline, phosphorylcholine, glutathione, cysteinylglycine, glutathione oxidized, NAD, and S-adenosylmethionine, mainly participating in glutathione metabolism, glutamate metabolism, ammonia recycling, and protein biosynthesis. Conclusion · Metabolic profiling of erlotinib-resistant lung adenocarcinoma cells was changed. The information of differential metabolites associated with erlotinib resistance could provide clues for new resistance mechanisms and potential metabolism-related drug targets.
