Discogenic low back pain is the common type of chronic low back pain. However,its mechanism has not been completely clarified. Considerable evidence shows that neurotrophins play an important role in discogenic low back pain. The paper summarizes the mechanism of neurotrophins on discogenic low back pain according to the pain transfer pathway of neurotrophins in intervertebral disc, dorsal horn ganglia and spinal trigeminal nucleus. Changing the pain transmission by regulating neurotrophins and its receptor will provide a new way for the treatment of discogenic low back pain.

Background Clinical effectiveness of intavitreal injection of glucocorticosteroid for macular edema has been verified,especially triamcinolone acetonide(TA).However,the efficacy and safety of combination of TA with macular laser grid photocoagulation for macular edema is concerned. Objective This clinical trial was to evaluate the efficacy and safety of intravitreal injection of TA combined with macular laser grid photocoagulation in the treatment of macular edema. Methods A case-cohort study was designed.One hundred and twenty eyes of 120 patients with macular edema from diabetes or retinal vein occlusion were included in this study.The patients were randomized into trial group and control group,with the matched age,course,visual acuity,intraocular pressure (IOP).The patients of the trial group received intravitreal injection of TA combined with macular laser grid photocoagulation,and those of the control group were managed with macular laser grid photocoagulation only.Best corrected visual acuity ( BCVA),optical coherence tomography(OCT),fundus fluorescein angiography(FFA) and IOP were examined before TA injection and 1 week,1 month,3 months,6 months after treatment and compared among different time points between two groups.Written informed consent was obtained from each patient prior to entering this trial. Results Compared with TA injection before,the BCVA was significantly elevated in the trial group 1 week,1 month,3 months and 6 months after TA injection( all P=0.000),however,no obvious improvement of visual acuity was found in the control group before and after treatment at any time point (P＞0.05 ).At various time points,the visual acuity was significantly improved in the trial group than the control group (P =0.037,0.000,0.002,0.046 ).Macular thickness was significantly decreased at various time points after TA injection in comparison with before TA injection in the trial group(all P=0.000),but no significant change in macular thickness in the control group between before and after treatment at any time point( P＞0.05 ).Macular thickness was lower in the trial group compared with the control group at various time points after treatment ( P＜0.05 ).Recurrence of macular edema was seen in 7 eyes ( 1 1.67％ ) 4-6 months,and the IOP raise( ＞21 mmHg)was found in 11 eyes( 14.1％ )after TA injection in the trial group.Conclusions Intravitreal injection of TA combined with macular laser grid photocoagulation can be an effective method in the treatment of macular edema.However,recurrence of macular edema or increase of IOP may occur in a few patients within 6 months after TA injection.A long-term follow-up should be performed for the evaluation of efficacy and safety after intravitreous injection of TA.

To investigate the effect and possible mechanism of echinacoside-containing serum on the osteogenic differentiation in rat bone marrow mesenchymal stem cells. Rat bone marrow mesenchymal stem cells were cultivated by the whole bone marrow adherence method. The 3rd generation of cells were divided into 3 groups: the blank control group, the classic osteogenic-induced group and the 10% echinacoside-containing serum group. The expression of alkaline phosphatase and osteocalcin were detected by ELISA. The ex- pression of ZHX, protein was detected by Western blot technique. RT-PCR technique was used to detect the expression of ZHX₃mRNA. According to the result, the expressions of the alkaline phosphatase and osteocalcin in the classic osteogenic-induced group and the 10% echinacoside-containing serum group were significantly higher than that of the blank control group (P <0. 01). And expressions of the alkaline phosphatase activity and osteocalcin in the 10% echinacoside-containing serum group were significantly higher than that in the classic osteogenic-induced group (P < 0.01). Meanwhile, the classic osteogenic-induced group and the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the black control group, with significant differences (P < 0.01); the 10% echinacoside-containing serum group showed obviously higher ZHX₃ protain and mRNA expression than that of the classic osteogenic-induced group, with a significant difference (P < 0.01). In conclusion, 10% echinacoside-containing serum can promote the differentiation of the bone marrow mesenchymal stem cells cultured in vitro. Its mechanism may be correlated with the increase in the ZHX₃expression.

Objective To analyze the outcome of patients receiving intrauterine insemination with husband sperm,in order to evaluate the effect of relative factors on pregnancy rate after intrauterine insemination. Methods Ninety-eight infertile couples who received intrauterine insemination in the Affiliated Hospital of Nantong University from March 2013 to May 2014 were selected as our subjects and 181 cycles were included. The information including clinical factors including maternal age,infertile time,infertile causes, ovulation induction protocol,time of insemination and postwash total motitle sperm(TMS)and pregnancy rate were recorded. Results (1)Totally 26 patients received clinical pregnancies,and clinical pregnancy rate(CPR) was 14. 36% per cycle. With age increase pregnancy rate decreased( χ2 = 1. 654 9,P = 0. 647).(2)The pregnancy rate of the patients was the same within the infertile time( χ2 = 1. 588 5,P = 0. 662).(3)The pregnancy rate of the patients with secondary infertility was lower than that of the patients with primary infertility,but there was no significant difference(χ2 = 0. 923 3,P = 0. 337).(4)The pregnancy rate of ovulation induction cycles was lower than that of nature cycles,but there was no significant difference(χ2 = 2. 222 0,P= 0. 136).(5)Postwash TMS was showed the same trend(χ2 = 0. 643 4,P = 0. 422). Conclusion In terms of intrauterine insemination with husband sperm,age,infertile time,infertile types,ovulation induction protocol and posrwash TMS can affect pregnancy rate,and the effects of various factors should be considered comprehensively in the process of therapy.

Objective To explore the behaviors caused by fear of hypoglycemia in type 2 diabetic patients, and deeply analyze the causes of these behaviors, providing help for medical staff to fully understand the inner demands of diabetic patients with hypoglycemia, so as to manage the blood glucose effectively, laying the foundation of Hypoglycemia Fear Survey-behavior scale suitable for domestic type 2 diabetic patients. Methods The interpretative phenomenological analysis method was used guided by the knowledge-attitude-belief-practice and social cognitive theory, 33 patients with hypoglycemia from 5 hospitals with different levels were interviewed by semi-structured interview. Results Four themes were extracted, including excess sensitivity, caution, avoidance and compromise. The theme excess sensitivity contained three kinds of behaviors, that were meal with sensitive alertness, drug sensitivity and excessive response to the hypoglycemia, while the theme caution contained two kinds of behaviors, that were strive to blood sugar stable and must prepare food.
