Objective To investigate the effects of subretinal fluid drainage combined with intravitreal anti-vascular endothelial growth factor (VEGF) drugs in the treatment of severe exudative retinal detachment Coats disease.Methods Thirteen patients (13 eyes) with 3B Coats' disease diagnosed at the Eye Center of Tongren Hospital were included in the study.The participants were aged from 1 year to 11 years with a mean age of (4.15 ± 2.99) years.The visual acuity was no light perception in 1 case,from light perception to counting finger in 7 cases,from 0.01 to 0.1 in 2 cases,and could not be measured due to young in 3 cases.Patients underwent retinal fluid drainage combined with intravitreal ranibizumab (IVR,0.5 mg,0.05 mL) at the pars plana of ciliary body,and with retinal laser photocoagulation or cryotherapy according to the retinal peripheral vascular activity.During the follow-up,the visual acuity,intraocular pressure,slit lamp,indirect ophthalmoscope and color ophthalmoscope were examined and observed.The abnormal blood vessel change,absorption of subretinal fluid,retinal reattachment and complication were observed.Results Two subretinal fluid drainage were performed in 3 cases,one subretinal fluid drainage in 10 cases.Six cases were combined with two intravitreal injections,4 cases with three intravitral injection,3 cases with intravitreal injection for more than three times.Five cases were treated with simple photocoagulation,3 cases with simple retinal cryotherapy,and 5 cases with laser combined with cryotherapy.In 13 patients,the visual acuity was improved in 2 cases,unchanged in 8 cases,and could not be measured due to young in 3 cases.Eight cases had complete retinal reattachment.No significant postoperative complications occurred during follow-up,such as endophthalmitis,retinal hole and vitreous hemorrhage.Conclusion Subretinal fluid drainage combined with intravitreal injection is an effective method for severe 3B stage Coats disease.

Collagen triple helix repeat containing 1 (CTHRC1) can repair the injured vessel by limiting the deposition of collagen and promoting cell migration.CTHRC1 is mainly regulated by Wnt-PCP signaling pathway,transforming growth factor (TGF)-bone morphogenetic protein (BMP) signaling pathway and extracellular signal-regulated kinase (ERK)-matrix metalloproteinase 9 (MMP9) signaling pathway.Recent studies have identified that CTHRC1 is aberrantly expressed in gastrointestinal cancers and associated with the occurring and development of cancers.

Objective To analyze the relationship between UDP-glucuronosyltransferase 1A1 (UGT1A1)gene polymorphism and delayed diarrhea caused by FOLFIRI treatment.Methods Two hundred and one blood samples were taken from patients with metastatic digestive tract tumor before chemotherapy by FOLFIRI and then the UGT1A1 * 28 genetic polymorphism was performed.All the cases treated with FOLFIRI were chosen to be observed and recorded by situation of the delayed diarrhea during chemotherapy,and to analyze the relationship between UGT1A1 * 28 genetic polymorphism and grade 3 and 4 delayed diarrhea.Results The distributions of the genotypes in 201 metastatic digestive tract tumor patients were as follows:UGT1A1 * 28 wild-type genotype TA6/6 (155,77.11％),heterozygous genotype TA6/7 together with homozygous genotype TA7/7 (46,22.89％).In the 201 cases,the incidences of grade 1 and 2 delayed diarrhea in the patients carrying wild-type genotype and mutant type were respectively 45.16％ (70/155),39.13％ (18/46).The incidences of grade 3 and 4 delayed diarrhea were respectively 9.68％ (15/155),19.57％ (9/46),with no statistical difference (x2 =3.318,P =0.190).Conclusion The UGT1A1 * 28 polymorphism TA6/7 or TA7/7 can not increase the risk of grade 3 or more severe delayed diarrhea for the patients with metastatic digestive tract tumor after receiving FOLFIRI treatment.

To investigate the relationship between the expression of early growth response gene 1 (EGR-1) and p38MAPK pathway in the paclitaxel resistance of ovarian carcinoma cells, the effect of p38MAPK inhibitor SB203580 on cell apoptosis was examined by using Hoechst 33258 staining. The intracellular Rh123 (Rhodamine 123) accumulation was detected by the flow cytometry (FCM). The 50% inhibition concentration (IC50) of paclitaxel for A2780/Taxol cells was determined by MTT method. Electrophoretic motility shift assay (EMSA) was employed to examine the EGR-1DNA binding activity. MDR1 and EGR-1 mRNA were assessed by RT-PCR. The expressed of p-gp, phosphorylated p53 and p38 were detected by Western blotting. SB203580 could remarkably promote the apoptosis of A2780/Taxol cells, and the cell apoptosis was in a time-dependent manner. Cellular Rh123 accumulation was increased, and the IC50 of paclitaxel for A2780/Taxol cells was decreased significantly. A2780/Taxol cell line after SB203580 treatment was shown to have a significantly higher level of EGR-1 DNA binding activity. SB203580 down-regulated the activity of p38MAPK pathway, but up-regulated EGR-1 expression. SB203580 significantly increased the level of cellular phosphorylated p53 protein, but decreased the p-gp protein level and MDR1 mRNA level in A2780/Taxol cells. There existed a close relationship between p38MAPK pathway and the paclitaxel resistance of ovarian carcinoma cells. The expression of EGR-1 mediated by p38MAPK pathway plays a critical role in paclitaxel resistance of ovarian carcinoma cells.

Objective To study the possibility of inducing human umbilical cord blood mesenchymal stem cells(MSCs) to differentiate into neuron-like cells by lithium chloride(LiCl) in vitro.Methods Human umbilical cord blood was collected from mature neonates.All samples were obtained sterilely with 20 U/ml heparin.The cord mononuclear cells were isolated with lymphocyte separation medium(density 1.077 g/ml), then purified by wall sticking screening and expanded with slight sugar DIEM containing 15% FBS.The third passage of the expanded MSCs were pre-inducted with DIEM containing 15% FBS and 20 ng/ml bFGF for 24 hours, then induced with DIEM without serum but 3 mol/L LiCl for 6 days in group A.The MSCs were induced with DIEM containing 3 mol/L Licl for 7 days in group B.The MSCs were normally cultured with DIEM containing 15% FBS in group C.The morphological changes of the cells were observed under phase contrast microscope.The neuron specific markers containing neuron specific enolase(NSE), microtubule associated protein2(MAP2) and glial fibrillary acid protein(GFAP) were evaluated by indirect immunocyto-chemistry staining.Results After inducted for 3 days, morphological changes were observed obviously in group A and B.6 days later, the differentiated cells showed typical neuronal morphology.The expression of NSE and MAP2 were positive for the majority cells in group A and B, and that of group A[(73.6 ± 7.8)%, 75.5 ± 8.5)% respectively]were obviously higher than group B[(31.0 ± 4.3)%,(33.5 ± 5.0)% respectively], few expressed GFAP in both groups.Conclusion The combination of LiCl and growth factor may induce the human umbilical cord blood MSCs into neuron-like cells in vitro.

OBJECTIVETo dynamically assess drug targeting of Yougui Pill (YP) and Zuogui Pill (ZP) using infrared thermography.

METHODSIn this self-control experiment, five healthy volunteers were recruited. By using infrared thermography 10 to 11 thermal images of different body locations were taken from each participant after they took warm water, YP, ZP, and their dissembled prescriptions at 30, 70, 100, 130, and 160 min, respectively. The heat values in the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) were statistically analyzed after scanning for 125 times.

RESULTSAdministration of YP and its disassembled prescriptions enhanced the heat value of the locations of the Du channel and Shenque (CV8), but did no enhance the heat value of the lower quadrant abdomen at 30 min. Administration of ZP and its disassembled prescriptions reduced the heat value in the locations of the lower quadrant abdomen, uterus, Du channel, and Shenque (CV8) at each time point.

CONCLUSIONThe drug targeting of ZP and YP focused on the locations of the Du channel and Shenque (CV8), not on the locations of the lower quadrant abdomen or uterus.

Objective To compare the effect of kidney-tonifying blood-activating recipe (KBR) and Aescuven Forte Tablets ( AFT) in improving the sperm quality of varicocele-induced male sterility, thus to optimize the therapeutic therapy for varicocele-induced male sterility. Methods A total of 102 varicocele-induced male sterility with abnormal sperm parameters after conservative treatment were randomized into KBR group (N=53) and AFT group ( N=49) . KBR group was given KBR plus natural vitamin E and AFT group was given AFT plus natural vitamin E, and the treatment lasted for 8 continuous weeks. Before and after treatment, the quality of seminal fluid was analyzed, sperm quantization parameters such as total number of sperm (TNS) , total number of progressive motility sperm ( TNPS) , total number of normal form sperm ( TNNS) and total number of nor mal form and progressive motility sperm ( TNNPS) were observed, and the improvement rate of sperm quantization parameter was compared. Results (1) Before treatment, the differences of TNS, TNPS, TNNS and TNNPS were insignificant between the two groups ( P>0.05) . After treatment, TNNS was not improved in AFT group ( P>0.05) , but TNS, TNPS, TNNPS were much improved in both groups ( P<0.01 compared with those before treatment) . The improvement of KBR group was superior to that of AFT group ( P<0.05) . ( 2) The improvement rate for TNS, TNPS, TNNS, TNNPS was 90.57%, 79.25%, 67.92%, 77.36%in KBR group, and was 75.51%, 73.47%, 28.57%, 61.22% in AFT group respectively. The improvement rate for TNS and TNNS in KBR group was superior to that in AFT group ( P<0.05 or P<0.01) . Conclusion Varicocele-induced male sterility patients usually have the syndrome of kidney deficiency and blood stasis, so KBR, which has the function of tonifying kidney and activating blood, has synergistic action on the effect of AFT in improving sperm quality of varicocele-induced male sterility patients.

Objective: To observe the clinical efficacy of herbal cake-partitioned moxibustion for dysmenorrhea due to deficiency cold. Methods: A total of 70 patients with dysmenorrhea who met the inclusion criteria were randomized into a mild moxibustion group and a herbal cake-partitioned moxibustion group by the random number table, with 35 cases in each group. Shenque (CV 8), Zhongji (CV 3) and bilateral Zigong (EX-CA 1) were selected for both groups. The treatment continued for 3 menstrual cycles. The visual analog scale (VAS) and COX menstrual symptom scale (CMSS) were scored in both groups before treatment, after treatment and at the end of the 3rd menstrual cycle after treatment. The clinical efficacy was evaluated at the end of the 3rd menstrual cycle after treatment. Results: After treatment, the clinical efficacy of the herbal cake-partitioned moxibustion group had the tendency to be superior to that of the mild moxibustion group, while there was no statistically significant difference in the overall efficacy between the two groups (P>0.05). The VAS and CMSS scores after treatment and at the follow-up were significantly lower than those before treatment in both groups (all P<0.05). At the follow-up, the VAS scores in both groups had no significant intra-group differences from those after treatment (both P>0.05). The CMSS scores in both groups were significantly lower than those after treatment (both P<0.05). The VAS scores at the follow-up of both groups had no statistical differences from those after treatment (both P>0.05). After treatment, the CMSS score in the herbal cake-partitioned moxibustion group was significantly lower than that in the mild moxibustion group (P<0.05). At the follow-up, there were no statistical differences in the CMSS score between the two groups (P>0.05). Conclusion: The herbal cake-partitioned moxibustion has the same therapeutic efficacy for dysmenorrhea as the mild moxibustion; the two moxibustion methods can significantly improve the concomitant symptoms of dysmenorrhea, and the herbal cake-partitioned moxibustion is little better.
