Objective To study the relationship between pain symptoms and the clinico-pathological features of pelvic endometriosis (EM).Methods One hundred thirty patients with laparoseopic diagnosis of EM were studied retrospectively and the relationship between pain symptoms including dysmenorrhea, chronic pelvic pain(CPP),dyspareunia and dysehezia and the anatomical features of pelvic endometriosis were evaluated.Results One hundred (76.9%)patients with pain symptoms and 30 (23.1%)without were included in this study.The number of patients with mild,moderate and severe dysmenorrhoea was 27 (20.8%),41(31.5%),and 32 (24.6%),respectively.Patients with dyspareunia,CPP and dyschezia were 46(35.4%),45(34.6%) and 67(51.5%),respectively.Compared with patients without dysmenorrhea,the proportion of deep utero-sacral nodules (45.0% vs 13.3%,P=0.00),recto-vaginal nodules (16.0% vs 0,P=0.01),complete obliteration of eul-de sac (41.0% vs 10.0%,P=0.00),and lesions of DIE (51.0% vs 16.7%,P=0.00) was significantly increased in patients with dysmenorrhea. The severity of dysmenorrhea was positively correlated with nodules in uterosacral ligaments (P=0.005,r= 0.302),and invasive depth of uterosacral ligaments (P=0.016,OR=5.085).Among patients with endometrioma,significantly more moderate to severe adhesions were found in patients with dysmenorrhea , compared with those patients without dysmenorrhea(29.1% vs 8.3%,P=0.029).Patients with CPP had more nodules in the utero-sacral ligaments(51.1% vs 30.6%,P=0.018)and DIE lesions(57.8% vs 35.3%,P=0.011),compared with those without.More nodules in the utero-saeral ligaments(46,3% vs 28.6%,P=0.028),recto-vaginal nodules(19.4% vs 4.8%,P=0.01),complete obliteration of cul-de sac(44.8% vs 22.2%,P=0.005)and DIE lesions(53.7% vs 31.7%,P=0.01)were found in patients with dyschezia,compared with those without.Nodules in the recto-vaginal pouch were an independent risk factor of dyspareunia.Conclusion Pain symptoms including dysmenorrhea,dyspareunia, chronic pelvic pain,and dysehezia are remarkedly related to endometriotic nodules at the posterior part of the pelvis or those with deep invasions.

Background The construction of tissue-engineered corneal endothelium needs the functional seeding cells,so how to culture a large amount of functional corneal endothelial cells (CECs) is an urgent problem to be solved.Objective The aim of this study was to evaluate the role of aqueous humor on bovine CECs in vitro.Methods Aqueous humor of 1.2 ml was collected from the anterior chamber of bovine and sterilized,and the liquid supernatant was obtained.The bovine CECs were isolated from bovine cornea and then cultured in low glucose Dulbecco Modified Eagle Medium with 10％ fetal bovine serum (FBS) in vitro.Aqueous humor was added into the medium with the final concentration of 2.5％,5.0％,l0.0％,15.0％ and 20.0％,respectively,and no aqueous humor was added in the control group.Cell counting kit-8 (CCK-8) assay was used to detect the absorbency value of CECs for the evaluation of cell proliferation.Progression of the cell cycle was analyzed by flow cytometry (FCM).After confluence of the cells was reached,1 ml plastic spear tip was used to scratch the cell single layer,and the cells were incubated consequently in medium with 10％ FBS and with or without aqueous humor for 24 hours.Healing area of the cell single layer was measured.The cells were incubated at a density of 6 × 105 cells/ml and cultured using medium with or without 10.0％ aqueous human for 5 days,and the number of the cells was analyzed by DAPI fluorescence technique.Results Under the phase-contrast microscopy,the confluent CECs showed a slabstone-like and hexagonal appearance.CCK-8 assay revealed that the absorbance values of CECs was significantly different among the various culture groups (F=4.051,P =0.007),and the absorbance value in different concentrations of aqueous human culture groups was significantly higher than that in the control group (P ＜ 0.01).FCM showed that the percentage of the cells in S-G2 phases was (34.80-±3.13)％ in the 10.0％ aqueous humors group and (23.06±1.13)％ in the control group,showing a significant difference (t =-5.729,P=0.005).The scratch test showed that the healing area of the cell signal layer was (0.116±0.019) mm2 in the 10.0％ aqueous humors group and (0.358 ±0.049) mm2 in the control group,showing a significant difference (t =13.842,P =0.000).The density of cells in the 10.0％ aqueous humor group was (1439± 1 10)/field,which was more than (1162±45)/field in the control group (t =-11.020,P=0.000).Conclusions Aqueous humor at the concentration of 10.0％ promote the growth and proliferation of bovine CECs.The result suggests that 10.0％ aqueous humor can be used as a promoting agent during the culture of CECs.

Objective:To reveal the primary mechanism of changing permeability in DENV-2 infected pHDMECs. Methods:pHDMECs was incubated by DENV-2 on the concentration of 103 TCID50 ,and the penetrability of the cell was detected by Transwell at 4,8,12,24,48 h,respectively. Then,the partial sequence of DENV-2 NS1 was analyzed by Real time-PCR,and NS1 protein was detected by immunofluorescence and flow cytometer (FCM). The apoptosis rate of pHDMECs was assayed by FCM. Finally,IL-6 and IL-8 secreted by pHDMECs were analyzed by Real time-PCR and double antibody sandwich ELISA. Results:The relative expression of NS1 gene was elevated but NS1 protein was not detected;the permeability of DENV-2 infected pHDMECs had dramatically increased both at 24,48 h,but the apoptosis rate has little changed even been influenced by DENV-2 at 72 h. However,the relative expression of IL-6/IL-8 mRNA was boosted at 8,24 h[(2. 49±0. 50) and (6. 82±1. 69) fold,respectively,P<0. 05]. In protein level,compared with control(869. 6±50. 70)pg/ml,IL-6 secreted by DENV-2 infected pHDMECs could reach by(1 248. 8±86. 9)pg/ml(P<0. 05),and IL-8 was(1 331. 0±86. 3)pg/ml(P<0. 05) while the control was (967. 6±156. 6)pg/ml. Conclusion:Indeed,pHDMECs can be infected by DENV-2;the increasing permeability of DENV-2 infected pHDMECs may not be caused by the pHDMECs′ apoptosis but the enhancing of pro-inflammatory cytokine IL-6 /IL-8.

Objective To investigate the effects of dengue type 2 virus(DENV-2)on the apopto-sis and autophagy of primary human hepatic sinusoidal endothelial cells(HHSECs)and the expression of ICAM-1 and Beclin-1 at mRNA level and to analyze the possible pathogenic mechanism of DENV-2. Meth-ods Immunohistochemistry(IHC)and flow cytometry analysis(FCM)were performed to identify HHSECs by detecting factor Ⅷ and CD31. The DENV-2 strain was identified by using PCR and HindⅢ. The 50%tissue culture infective dose(TCID50 )of DENV-2 was calculated after infecting C6 / 36 cells with DENV-2. Dynamic changes of DENV-2 NS1 were measured by real-time PCR after infecting HHSECs with DENV-2. CCK-8 was used to dynamically detect the cytotoxicity of DENV-2 to HHSECs. The transcriptional levers of Beclin-1 and ICAM-1 in DENV-2-infected HHSECs were detected by real-time PCR. FCM was performed to analyze the apoptosis of HHSECs and the expression of LC3B and ICAM-1. Results The cells in the exper-imental group were stained brown by DAB and the positive expression rate of CD31 reached 87. 1% . The TICD50 of DENV-2 to C6 / 36 cells was 10-6. 845 / 0. 1 ml. Compared with the uninfected cells,partial se-quences of NS1 gene were expressed in DENV-2-infected HHSECs. DENV-2 suppressed the cell activities of HHSECs. The suppression rates of DENV-2 to HHSECs at 12 h,24 h,36 h and 48 h were respectively (10. 90±1. 24)% ,(16. 40±0. 42)% ,(17. 00±0. 46)% and(29. 60±0. 26)%(P﹤0. 05). The tran-scriptional levels of Beclin-1 and ICAM-1 in HHSECs were significantly increased at the time point of 24 h after DENV-2 infection,the 2-△△Ct values of which were 46. 77±2. 55 and 40. 97±4. 91,respectively. The expression of LC3B and ICAM-1 in DENV-2-infected HHSECs were increased,the peaks of which were reached at 24 h(14. 7% )and 36 h(35. 5% ),respectively. The apoptosis of DENV-2-infected HHSECs was remarkably enhanced at 12 h with an apoptosis rate of 13. 17% . Conclusion HHSECs was susceptible to DENV-2. DENV-2 induced the upregulation of ICAM-1 and the activation of HHSECs. Moreover,autoph-agy and apoptosis of HHSECs could also be induced by DENV-2.

AIM:To explore the application of 10g/L cyclopentolate chloride eye drops in children, and to compare the different effectiveness of cycloplegia between 10g/L cyclopentolate chloride and atropine in Chinese children.METHODS:A total of 236 eyes of 118 children aged 3~12 years old were enrolled in this study including 80 eyes of 40 children with myopia, 156 eyes of 78 children with hyperopia and 146 eyes of 73 children combined with astigmatism. 10g/L cyclopentolate chloride eye drops were used once per 5min for 3 times and refractive diopter was obtained 1h after the last drop of cyclopentolate. Three days after that, 10g/L atropine was then used 1 time per night for 1wk and optometry was performed again. The children were divided into 3 groups ( myopia, hyperopia and astigmatism group ) according to the refractive status, in which astigmatism was independent of the degree of separation of cylinder statistics. The results of retinoscope refraction were then compared between 10g/L cyclopentolate and 10g/L atropine.
RESULTS:The refractive diopter was -2. 25±1. 31D after 10g/L cyclopentolate eye drops and -2. 23±1. 32D after 10g/L atropine in myopic group. The refractive diopter was 1. 35±1. 19D and 1. 38±2. 00D in astigmastic group. No significant difference was found in myopic group and astigmastic group (P= 0. 109, P= 0. 374). While in the hyperopic group, the refractive diopter was 3. 76±2. 4D after 10g/L cyclopentolate eye drops, which was lower than that after 10g/L atropine 4. 39±2. 6D (P=0. 000).
CONCLUSION: The results of this study suggest that 10g/L cyclopentolate chloride eye drops can be used in myopia and astigmatism children, and 10g/L atropine should be used in hyperopia children.

OBJECTIVETo study the effects of rhynchophylline, isorhynchophylline, and rhynchophylla alkaloids on the vascular adventitial fibroblasts (VAF) apoptosis and proliferation in thoracic aorta of spontaneously hypertensive rats (SHR), and on the Bcl-2, Bax, c-Fos, c-Myc, laminin (LN), and fibronectin (FN).

METHODSForty 8-week old male SHR were randomly divided into five groups, i. e., the model group, the captopril group (17.5 mg/kg), the isorhynchophylline group (5.0 mg/kg), the rhynchophylline group (5.0 mg/kg), and the rhynchophylla alkaloids group (50.0 mg/kg), 8 in each group. In addition, eight 8-week old male Wistar rats were selected as the normal group. Equal volume of normal saline was given to rats in the normal group and the model group by gastrogavage. Rats in the rest groups were perfused with isovolumic medication solution (10 mL/kg), six days per week for eight successive weeks. The dosage of drugs was adjusted according to the change of body weight. The VAF apoptosis rate of the thoracic aorta was measured by Annexin V-FITC combined with PI dyeing and flow cytometry. The protein expressions of thoracic aortic Bcl-2, Bax, c-Myc, c-Fos, FN, and LN were detected by immunohistochemical assay. The adventitial transforming growth factor beta1 (TGF-beta1) mRNA expression in the thoracic aorta was detected by in situ hybridization method.

RESULTSCompared with the model group, the tail arterial systolic pressure decreased, the VAF apoptosis and the protein expression of Bax increased, Bcl-2, c-Fos, FN, LN, and TGF-beta1 mRNA all decreased in the thoracic aorta of SHR in each treatment group after 4-and 8-week of intervention. Rhynchophylline, isorhynchophylline, and rhynchophylla alkaloids could inhibit the protein expression of c-Myc with statistical difference (P<0.05, P<0.01). Compared with the captopril group, there was no statistical difference in decreasing the tail arterial systolic pressure, the protein expression of c-Fos and the mRNA expression of TGF-beta1 among the rhynchophylline group, the isorhynchophylline group, and the rhynchophylla alkaloids group (P>0.05). There was statistical difference in increased VAF apoptosis and decreased protein expressions of Bcl-2, c-Myc, and LN (P<0.05, P<0.01). There was statistical difference in increased protein expression of Bax between the rhynchophylline group and the isorhynchophylline group (P<0.05, P<0.01). There was statistical difference in decreased protein expression of FN in the isorhynchophylline group (P<0.05). There was no significant difference among the rhynchophylline group, the isorhynchophylline group, or the rhynchophylla alkaloids group (P>0.05).

CONCLUSIONSRhynchophylline, isorhynchophylline, and rhynchophylla alkaloids might promote the VAF apoptosis in the thoracic aorta of SHR by regulating the protein expressions of Bcl-2 and Bax. They might inhibit the VAF proliferation by restraining protein expressions of c-Fos, c-Myc, and TGF-beta1 mRNA. They also might improve the thoracic aorta wall reconstruction and decrease the tail arterial systolic pressure by down-regulating the protein expressions of FN and LN, and attenuating the deposition of extracellular matrix.
