Objective: To compare the cytotoxic activity of mammaglobin A-specific CD8+ cytotoxic T lymphocytes (CTLs) and cytokine-induced killers (CIKs) against breast cancer cells in vitro. Methods: PBMCs were isolated in vitro from the peripheral blood of healthy volunteers. Then DCs, CTLs and CIKs were isolated, induced and cultured from PBMCs in vitro. CD8+ CTLs were purified with immunomagnetic beads from CTLs. DCs were infected with recombinant adenovirus encoding mammaglobin A(Ad-MGBA). CTLs and CIKs were co-cultured with DCs being infected with Ad-MGBA. The cytotoxic activity of mammaglobin A-specific CD8+ CTLs and CIKs against breast cancer cells was compared by flow cytometry. Results: The apoptosis rate of breast cancer cell MDA-MB-415, which expressed MGBA was 63.07% by CD8+ CTL killing and 48.35% by CIK killing (P<0.05). The apoptosis rate of breast cancer cell MDA-MB-231, which could express MGBA was 14.62% by CD8+CTL killing and 29.29% by CIK killing (P<0.05). Conclusion: The cytotoxic activity of antigen-specific CD8+ CTLs for the same antigen-expressing oncology cells is higher than CIKs. However, for different antigen-expressing oncology cells, the cytotoxic activity of CD8+CTLs is lower than that of CIKs.

Mycotic vaginitis is a common and frequently-occurring gynaecopathia and easy to attack repeatedly, so painful to patients. In this study, the authors observed the clinical efficacy of Sophora gel combined with Fluconazole capsules in treating mycotic vaginitis, in order to seek an effective method for treating mycotic vaginitis. Totally 85 patients with mycotic vaginitis treated in our hospital between December 2012 and July 2014 were randomly divided into the treatment group (43 patients) and the control group (42 patients). The treatment group was given vaginally Sophora gel (one piece every night for 14 days) and orally Fluconazole capsules (150 mg, once every three days, four times in total); The control group was only administered with Fluconazole capsules. The total efficacy, cure rate, recurrence rate and clinical symptom improvements of the two groups were observed. The results show that the total efficacy, the cure rate and the recurrence rate of the treatment group vs. the control group were respectively 97.7%, 90.7% and 2.6% vs. 83.3%, 71.4% and 20.0%, with statistical significance in their differences (P < 0.05). The treatment group showed reduced leucorrhea, pruritus vulvae disappearance and earlier mucosal hyperemia disappearance than the control group, with statistical significance in their differences (P < 0.05). In conclusion Sophora gel combined with Fluconazole capsules can improve antifungal activity of drugs, relieve clinical symptoms, shorten the course of disease, enhance the cure rate and reduce the recurrence rate; So this therapy can be widely applied in clinic.

Objective To identify and characterize uveal melanoma associated protein variants with two-dimensional electrophore- sis and mass spectrometry.Design Experiment study.Participants 4 cases of specimens of uveal melanoma and 4 cases of normal con- tributed uveal tissue.Methods Proteins from uveal melanoma and normal urea were separated with two-dimensional eleetrophoresis (2-DE)and visualized with Coomassie G-250.Gels were analyzed by Image Master 5.0 software.The mass spectra were measured by matrix-assisted laser desorption/ionizatian time-of-flight mass spectrometry(MALDI-TOF MS)and searched against NCBI database using Mascot software.Main Outcome Measures Differential proteins.Results A set of 30 proteins were differentially expressed in uveal melanoma compared to nomal urea.Twenty-four types of protein only expressed in uveal melanoma.Five types of protein were up-regu- lated and 1 type of one down-regulated.These proteins can be subdivided into groups according to cellular function,such as enzyme, signal transduction,signal regulation,cytoskehton,immune,etc.Conclusions There is significant difference in protein profilings be- tween uveal melanoma and normal uvea.The differentially expressed proteins may be associated with the development of uveal melanoma.

To assess the efficacy and safety of a new traditional Chinese medicine called Naomaixin granules in the treatment of arterial cerebral infarction in convalescent. Methods: A randomized, double-blind and parallel controlled clinical study was carried out, and three sets of parallel controlled clinical design with the test group, positive drug group and placebo group were per-formed. The clinical efficacy of Naomaixin granules on arterial cerebral infarction in convalescent was confirmed based on the main ef-fective indicators including NIHSS scale score and the life state assessment for the patients. Meanwhile, the curative effect of Naomaixin granules on stroke disease with Qi deficiency and blood stasis ( QDBS) was observed. The safety of Naomaixin granules was evaluated as well. Results:The clinical design enrolled a total of 177 cases of patients, including 60 ones in Naomaixin granules group, 59 ones in Mailuotong granules group and 58 ones in the placebo group. After the 4-week treatment,NIHSS scale score, life skills, TCM syn-dromes efficacy and the curative effect of Naomaixin granules group and Mailuotong granules group were better than those of the placebo group(P<0. 01 or P <0. 05). Furthermore, compared with Mailuotong granules group, the curative effect of Maomaixin granules group was much better (P<0. 05). The incidence of adverse events of the test group, positive drug group and placebo group respec-tively was 1. 67%,1. 69% and 1. 72% without statistical significance (P>0. 05). No serious adverse events appeared during the ob-servation. Conclusion:Naomaixin granules are safe and effective in the treatment of atherosclerotic cerebral infarction in convalescen.

OBJECTIVETo explore the suppression effect of human cytomegalovirus (HCMV) on megakaryocytes and their precursors and study the antiviral effect of antisense phosphorothioate deoxyoligonucleotide (ASON) against HCMV.

METHODSCD34(+) cells were induced to proliferate and differentiate committedly to megakaryocytes in a semi-solid CFU-MK culture system. Cultured cells and ASON pretreated CD34(+) cells were infected by HCMV of AD169 strain. HCMV immediate early protein (IEP) DNA and mRNA and UL36 mRNA were detected by PCR and reverse transcription-polymerase chain reaction (RT-PCR). Cytotoxicity was evaluated by MTT assay.

RESULTSHCMV AD169 suppressed the proliferation of megakaryocytes significantly. Compared with the mock group, the CFU-MK yields were decreased by 21.6%, 33.8%, and 46.3%, respectively, in 3 different titers of virus infected groups (P < 0.05). The suppression was virus titer dependent. HCMV IEP DNA, HCMV IEP mRNA and UL36 mRNA were detected in the colony cells of viral infection group. Compared with the infected group by HCMV AD169, UL36Anti treatment at 0.08 micromol/L could recover the CFU-MK yields significantly (P < 0.05). In the infected MK, which was pretreated with UL36Anti at 0.08 micromol/L, HCMV UL36 mRNA was undetectable by RT-PCR. The oligonucleotide MM(1) containing a G-to-C substitution in UL36Anti was inactive at 0.08 micromol/L but active at 0.40 micromol/L. The concentration of UL36Anti necessary to significantly affect cell growth was 90.00 micromol/L.

CONCLUSIONSHCMV AD169 infection inhibits the proliferation and differentiation of megakaryocytes and their precursors. There are early transcriptions of HCMV IE and UL36 protein in infected CFU-MK. The specific ASON has a definite anti-HCMV activity.

OBJECTIVETo study the concentrations of IL-4 and IL-13 in bronchoalveolar lavage fluid (BALF) in neonates with respiratory distress syndrome (RDS) and concurrent ventilator-associated pneumonia (VAP).

METHODSSixty-eight neonates with RDS undergoing mechanical ventilation for over 48 hrs were enrolled. IL-4 and IL-13 levels in BALF were measured using ELISA 1, 72 and 96 hrs after mechanical ventilation. The results were compared between the neonates with concurrent VAP (n=37) and without (n=31).

RESULTSThe levels of BALF IL-4 96 hrs after ventilation in the VAP group (35.34+/-1.78 ng/mL) were significantly higher than those in the non-VAP group (13.69+/-2.47 ng/mL, P<0.05). The levels of BALF IL-13 96 hrs after ventilation in the VAP group (33.74+/-2.74 ng/mL) also increased significantly compared with those in the non-VAP group (13.50+/-3.81 ng/mL) (P<0.05). There were significant differences in BALF IL-4 and IL-13 levels between 1 hr and 96 hrs in the VAP group (P<0.05).

CONCLUSIONSBALF IL-4 and IL-13 levels increase in neonates with RDS and concurrent VAP. IL-4 and IL-13 may involve in the regulation of the inflammatory immune response.

Objective To investigate the role of mitochondrial permeability transition pore (mPTP) of hippocampal neurons in process of hydrogen-rich saline attenuating global cerebral ischemia-reperfusion (I/R) injury in rats.Methods Seventy-two male Sprague Dawley rats,weighing 250-300 g,were randomly divided into six groups ( n =12 each):sham operation group (group S),cerebral ischemia-reperfusion group (group IR),normal saline group (group NS),hydrogen-rich saline group (group H),atractyloside group (group A) and hydrogen-rich saline + atractyloside group (group HA).Global cerebral I/R injury was produced by four-vessel occlusion method.Bilateral vertebral arteries were cauterized.Then bilateral common carotid arteries were occluded for 15min and followed by reperfusion.In groups H and HA,hydrogen-rich saline 5 ml/kg was injected intraperitoneally immediately after reperfusion,while equal volume of normal saline was injected in the other four groups.The rats in groups A and HA received intracerebroventricular injection of atractyloside 15 μl 10 min before reperfusion,while groups NS and H received intracerebroventricular injection of equal volume of normal saline.After the neurological behavior was evaluated at 24 h of reperfusion,8 rats in each group were sacrificed and the hippocampi were immediately isolated and homogenized followed by density gradient centrifugation.The opening degree of mPTP was assayed with spectrophotometry and the mitochondrial membrane potential (MMP) was detected with Rhodamine 123 method.Four rats in each group were killed at 72 h of reperfusion and the brains were removed for microscopic examination of the area CA1 of the hippocampus and determination of the number of normal pyramidal neurons.Results Compared with group S,the neurological behavior was compromised,MMP was decreased and mPTP opening degree was enhanced in the other five groups ( P ＜ 0.05).The neurological behavior was better,MMP was increased and mPTP opening degree was decreased in groups H and HA as compared with group IR ( P ＜ 0.05).Compared with group H,the neurological behavior was compromised,MMP was decreased and mPTP opening degree was enhanced in group HA ( P ＜ 0.05).Compared with group IR,the number of normal pyramidal neurons at 72 h of reperfusion in the CA1 region of the hippocampus was higher in group HA ( P ＜0.05).The injury of the CA1 region of the hippocampus at 72 h of reperfusion was attenuated in group H as compared with groups IR,NS,A and HA.Conclusion Hydrogen-rich saline can attenuate global cerebral I/R injury throngh inhibiting the mPTP opening and reducing the dissipation of MMP,thus maintaining the mitochondrial function.

?AlM: To investigate the outcome and safety of Ahmed glaucoma valve implantation treatment in uncontrolled primary congenital glaucoma ( PCG) .
? METHODS: Twenty - two eyes in 22 children with uncontrolled PCG were reviewed retrospectively and underwent Ahmed glaucoma valve implantation treatment from January 2011 to December 2014. Main checking index included intraocular pressure ( lOP ) before and after operation, corneal diameter and complications.
?RESULTS: Preoperative mean age was 3. 74±2. 24y, and 2. 59 ± 1. 78y apart from the last operation. Postoperative average lOP was 35. 22 ± 6. 36mmHg. Average corneal diameter was 12. 79 ± 0. 75mm. Mitomycin C ( 0. 3 - 0. 5mg/mL ) was used in all operations for 3-5min. Glaucoma valves were implanted in the temporal or nose above the equator sclera. Postoperative lOP was 11. 4±4. 45mmHg at 1wk, and 16. 73± 7. 23mmHg after 12mo. As lOP< 21mmHg for success criteria, lOP of 16 eyes ( 73%) were controlled after 12mo. Preoperative 6 cases had shallow anterior chamber, recovered spontaneously. No serious complication was recorded, such as rejection of glaucoma valve, endoophthalmitis and corneal decompensation.
?CONCLUSlON:Ahmed glaucoma valve implantation in uncontrolled PCG is a safe and viable treatment.
