The Journal of Practical Medicine 2016;32(1):73-75
Objective To detect the effect of insulin-like growth factor-1 (IGF-1) at varied levels in pregnancy maternal serum and cord serum of patients with the polycystic ovary syndrome (PCOS) on pregnancy outcomes, and explore whether IGF-1 could be used as a diagnostic marker for PCOS. Methods From January 2012 to December 2013, pregnancy maternal and cord serums were collected from 120 PCOS patients and 120 normal pregnant women in the Department of Obstetrics and Gynecology of our hospital. ELISA was used to detect the levels of IGF-1, and analyze the levels of IGF-1 in different pregnancy outcomes between normal pregnant women and PCOS patients. Results Compared with the control group, the levels of IGF-1 in pregnancy maternal and cord blood were increased significantly in patients with PCOS (P< 0.05). The incidence of stillbirth, premature delivery and macrosomia was significantly higher in PCOS patients. The levels of IGF-1 in pregnancy maternal and cord serum were significantly higher in all PCOS patients with adverse pregnancy outcomes compared with the control group (P < 0.05). Conclusion IGF-1 could be used as a risk prediction marker for pregnancy outcome in patients with PCOS.

The Journal of Practical Medicine 2017;33(10):1608-1611
Objective To analysisthe evaluation clinical effects and complications of retrograde peroneal artery perforators and retrograde posterior tibial artery fascia pedicle flap perforators fascia pedicle flap for the re-pair of the leg and foot skin defect effect. Methods In January 2010 to January 2015,patients with leg and foot skin defect effect in our hospital administrated withperoneal artery perforators and retrograde posterior tibial artery fascia pedicle flap perforators fascia pedicle skin flap were retrospectively analyzed.Flap survival,necrosis rate, the function of the skin flap and complications were analyzed. Results The one stage flap survival rate of peroneal artery group(84.6%)is higher than the posterior tibial artery group(57.69%),the difference was statistically sig-nificant(P < 0.05). There were no significant difference between the flap function index(pain,activity limita-tion,wearing shoes,functional recovery satisfaction)score and posterior tibial artery group(P>0.05). The occur-rence of hyperplastic scar,itching,pigmentation,skin graft,numbness,skin graft abnormal pain complication rates inperoneal artery group were significantly lower than the posterior tibial artery ,and the difference was statisti-cally significance(P < 0.05). Conclusion Retrograde peroneal artery perforators and retrograde posterior tibial artery fascia pedicle flap perforators fascia pedicle flap can effectively repair skin and soft tissue defect ,retrograde peroneal artery perforators shows with higher survival rate and less complication.

5.Application and biocompatibility of pedicle screws for the internal fixation of thoracolumbar vertebra fracture
Chinese Journal of Tissue Engineering Research 2007;0(43):-
OBJECTIVE:To study the application and development of pedicle screws for the internal fixation of thoracolumbar vertebra fracture and to evaluate the biocompatibility. METHODS:A computer-based online search was conducted in Medline database and CNKI with the OBJECTIVE:To study the application and development of pedicle screws for the internal fixation of thoracolumbar vertebra fracture and to evaluate the biocompatibility. METHODS:A computer-based online search was conducted in Medline database and CNKI with theof "pedicle screws,thoracolumbar,fractures,biocompatibility" in both Chinese and English from 1989 to June 2009. A total of 32 out of 57 articles were included according to inclusion and exclusion criteria to summarize the treatment of thoracolumbar vertebra fracture using pedicle screws and the complication prevention and cure of pedicle screws,and to investigate clinical application,biocompatibility,and prevention of interruption of pedicle screws. RESULTS:Internal fixation of posterior pedicle screws was an effective method to treat thoracolumbar vertebra fracture; however,breakage of pedicle screws was easily caused following internal fixation. Pedicle screws combined with implantation of autogenous bone or artificial materials into cavity of injured vertebra could effectively relieve loosening and interruption of implants; however,the price was expensive. Sufficient bone graft for internal fixation and implant dislodgment following bone fracture healing might effectively prevent interruption of internal fixation device. Pedicle screw intension of stainless steel materials was strong,but the biocompatibility was poor. While,the biocompatibility of titanium materials was great,but the intension was weak,thus the pedicle screws were easily broken. CONCLUSION:Internal fixation of pedicle screws is an effective method to treat thoracolumbar vertebra fracture. However,the biocompatibility still needs to be improved. Titanium pedicle screws have a good biocompatibility but poor intension; however,stainless steel pedicle screws have a good intension but poor biocompatibility.

AIM: To evaluate the efficacy, safety and effects on changes of T lymphocyte subsets of mycobacterium phlei and cisplatin in treatment of patients with malignant pleural effusion (MPE). METHODS: 62 patients of MPE were randomly assigned to two groups. The test group was treated once a week lasting for 1-3 weeks with NS 20 ml + mycobacterium phlei 8.6 ?g + cisplatin 40 mg, while the control one with NS 20 ml + cisplatin 40 mg only. The efficacy and changes of T lymphocyte subsets before and after therapy were analyzed separately. RESULTS: The overall response rate in the test group was 87.5 %, which meant significantly higher than that in the control group (P

Objective To explore the silence of B-cell specific Moloney murine leukaemia virus insertion site 1(Bmi-1)by RNA interference on the proliferation of human leukemia cell line K562 and its mechanisms.Methods Small interfering RNA(siRNA)targeting Bmi-1 gene was designed and double-stranded siRNA was chemically synthesized.After double-stranded siRNA was transfected into K562 cells with Lipofectamine 2000,the proliferation of K562 cells was detected by MTT colorimetry,cell cycle was determined by flow cytometry,and the expression of Bmi-1 and P16 were analyzed by Western blotting.Results The siRNA targeting human Bmi-1 gene effectively prolonged the double time of K562 cells,increased the percentage of cells at G1 phase,and the expression of Bmi-1 was significantly down-regulated but the expression of P16 was up-regulated.Conclusion The siRNA targeting human Bmi-1 gene inhibits the proliferation of K562 cells,and up-regulates the expression of P16 in the cells.

0.05) during spinal cord monitoring. The values of SEP amplitudes at the 2nd stage was higher in comparison with that of the 1st stage(P0.05). There were 5 patients false-positive(3.2% ) when the values of SEP at pre-incision was used as baseline, while no false-positive case was found in spine exposure baseline. Conclusion Some variability of latencies and amplitudes during different stages of scoliosis surgery is normal. The study results suggest that to determine the SEP after spine exposure as the reference baseline is more reliable for intraoperative spinal cord monitoring.

10.Susceptibility genes for diabetic retinopathy
International Eye Science 2008;8(2):234-239
Diabetic retinopathy (DR) is a sight-threatening chronic complication of diabetes mellitus and is the leading cause of acquired blindness in adults. Long-term exposure to the hyperglycemia of diabetes patients leads to the development of DR. Several studies have provided evidence that good diabetes control is important to prevent DR. However, emerging evidence suggests that genes are a significant contributor to an individual's risk of retinopathy. This evidence is from evaluations of familial aggregation and different incidence of DR in racial and ethnic groups. Some groups of patients develop DR despite good control and some escape retinopathy despite poor control. This suggests that the genes are involved in the susceptibility to DR. Genes suggested as having a role include those encoding aldose reductase, nitric oxide synthase, receptor for advanced glycation end products, angiotensin converting enzyme, vascular endothelial growth factors and pigment epithelium-derived factor. An understanding of the role of susceptibility genes will ultimately allow the development of novel therapeutic strategies. This article reviews the role of genetic factors in the etiology and progression of DR.
