Objective To investigate the expression and significance of Th9, Th17 and CD4+CD25+Foxp3+regulatory T (Treg) cells as well as the related cytokines (IL-9, IL-17, TGF-β) in peripheral blood of patients with adult primary immune thrombocytopenia ( ITP) . Methods Peripheral blood samples were collected from 47 patients with ITP and 39 age-and sex-matched healthy subjects. The percentages of Th9, Th17 and CD4+CD25+Foxp3+Treg cells in peripheral blood samples were detected with flow cytometry. The levels of IL-9, IL-17 and TGF-βin serum samples were detected by enzyme linked immunosorbent assay ( ELISA) . Results Compared with healthy subjects, the percentages of Th9 and Thl7 cells and the concen-trations of IL-9 and IL-17 in patients with ITP were significantly increased [(1. 27±0. 31)% vs (0. 71± 0. 26)%, P<0. 05;(2. 01±0. 42)% vs (0. 97±0. 32)%, P<0. 05. (26. 52±7. 48) ng/L vs (16. 16± 5. 27) ng/L, P<0. 05;(10. 97±3. 94) ng/L vs (7. 14±2. 73) ng/L, P<0. 05]. The percentages of CD4+CD25+Foxp3+ Treg cells and the concentrations of TGF-β in patients with ITP were lower than those in healthy subjects [(4. 69±0. 85)% vs (7. 16±1. 92)%, P<0. 05. (3. 76±1. 28) μg/L vs (6. 41±1. 83)μg/L, P<0. 05]. Moreover, the blood platelet counts in patients with ITP were negatively correlated with the percentages of Th9 and Th17 cells and the concentrations of IL-9 and IL-17 (γs=-0. 349, P=0. 037;γs=-0. 392, P=0. 031;γs=-0. 436, P=0. 014;γs=-0. 401, P=0. 027), but were positively correlated with the percentages of CD4+CD25+Foxp3+ Treg cells and the concentrations of TGF-β (γs=0. 411, P=0. 024;γs=0. 407, P=0. 026). Conclusion The imbalanced distribution of Th9, Th17 and Treg cells and the abnormal expression of related cytokines (IL-9, IL-17 and TGF-β) in patients with ITP might be the possible immunological pathogenesis of ITP.

Objective To evaluate the quality of life and influencing factors in patients with breast cancer after breast-conserving surgery, so as to provide theoretical support for preoperative health education and postoperative rehabilitative intervention for these patients. Methods 120 breast conserving surgery (BSC) and 140 modified radical mastectomy (MRM) patients were assessed with Functional Assessment of Cancer Therapy-Breast (FACT-B V4.0) one week after operation. Life quality was evaluated between the two groups, and the influencing factors were also analyzed. Results Postoperative breast cancer patients after breast conserving surgery were with good breast complementary attention, lower emotion state. The other scores of quality of life had no statistical difference. Influencing factors on the quality of life of breast cancer patients were anxiety state, relationship of family members, position of surgery and character type. Conclusions It suggests that nursing specialists should make out corresponding, scientific and reasonable nursing intervention schemes based on the characteristics of different groups of people to ease psychological burden, and elevate the quality of life effectively for postoperative breast conserving surgery patients.

Objective To evaluate the effect of electro-acupunctare at Zusanli on liver injury in a rat model of sepsis after scald.Methods Fifty SPF male Sprague-Dawley rats,weighing 200-250 g,aged 2-3 months,were randomly divided into 5 groups (n =10 each) using a random number table:control group (group C); sepsis after scald group (group SS); electro-acupuncture at Zusanli group (group E); electric stimulation of non-acupoint group (group NE); electro-acupuncture at Zusanli + α-bungarotoxin (α-BGT) group (group α-BGT).The rats were subjected to a third degree scald covering 20％ of the total body surface area (TBSA) and sepsis was induced with muramyl dipeptide (MDP) 5 mg/kg injected into the femoral vein immediately after scald.Electro-stimulation (3 V,2 ms,3 Hz) of bilateral Zusanli acupoints or non-acupoints was performed for 12 min every 8 h for 2 consecutive days starting from the time point immediately after MDP was injected in group E.In group NE,electro-stimulation was performed at the points 5 mm lateral to the acupoints of bilateral Zusanli and the method was similar to those previously described in group E.In group α-BGT,α-BGT 1.0 μg/kg (in normal saline 1 ml) was injected into the femoral vein before electric stimulation,then electro-stimulation was performed and the method was similar to those previously described in group E.After 48 h of continuous stimulation,liver specimens were obtained for microscopic examination of the pathological changes.The blood samples were obtained from the abdominal aorta for determination of the levels of serum ALT and AST,tumor necrosis factor-alpha (TNF-α),and high mobility group box-1 (HMGB1) (by ELISA),and expression of Nod-like receptor 2 (NLR2) mRNA (by RTPCR) and receptor-interacting protein 2 (RIP2) in the liver tissues (by Western blot).Results The serum ALT and AST,TNF-α and HMGB-1 levels and NLR2 mRNA and RIP2 expression in liver tissues were significantly higher in SS group than in C group.Compared with SS group,the serum ALT,AST,TNF-α and HMGB1 levels were significantly decreased and NLR2 mRNA and RIP2 expression was down-regulated in E group,and no significant changes were found in the parameters mentioned above in NE group.Compared with E group,the serum ALT,AST,TNF-α and HMGB1 levels were significantly increased,and NLR2 mRNA and RIP2 expression was up-regulated in α-BGT group.The pathological changes in liver tissues were significantly reduced in group EA as compared with SS,NE and α-BGT groups.Conclusion Electro-acupuncture at Zusanli can reduce liver injury in a rat model of sepsis after scald and inhibition of NLR2/RIP2 signaling pathway and activation of cholinergic antiinflammatory pathway mediated by α7 nicotinic acetylcholine receptors in liver tissues may be involved in the mechanism.

Important measures to reduce mortality include curing the underlying diseases, emphasis on mornitoring fungal pathogen and susceptibility tests, early diagnosis and compliance medication principles.

AIM: To report the safety and effectiveness of LenSx femtosecond laser-assisted cataract surgery.
● METHODS: Sixty - seven patients ( 76 eyes ) were included in the study. All the cases underwent LenSx femtosecond laser-assisted cataract surgery between Jul. 2014 and Jul. 2015. The completion rate of anterior capsulotomy, lens fragmentation, intraocular lens implantation and corneal incisions, the best corrected distance visual acuity ( CDVA ) before and 1mo after femtosecond laser-assisted cataract surgery, the adverse events and equipment defect rate were recorded. The regression analysis of possible factors affecting the completion rate of corneal incision ( eye, age, location of incision, corneal diameter, peripheral corneal thickness, preoperative corneal astigmatism) was taken.
● RESULTS: All surgeries were uneventful. The completion rate of anterior capsulotomy, lens fragmentation, intraocular lens implantation and corneal incisions was 97%, 100%, 100% and 83%, respectively. No adverse events ( posterior capsule rupture, corneal edema, macular edema and retinal detachment ) and device defect occurred. The CDVA was significantly improved 1mo after surgery. Logistic regression analysis showed that there was a correlation between location of corneal incision and completion rate of corneal incision, and no correlation was found between eye, age, corneal diameter, peripheral corneal thickness, preoperative corneal and completion rate of corneal incision.
●CONCLUSION: The LenSx femtosecond laser-assisted methodis efficient and safe for cataract surgery.

Objective To explore the effects of microRNA(miR)-1283 on invasion,proliferation and apoptosis of HTR 8/SVneo cell line derived from human-trophoblast cells.Methods HTR-8/SVneo cells were divided into three groups,as-miR 1283 group was transfected with miR 1283 analogues,anti-miR-1283 group was transfected with miR-1283 inhibitors,and negative control group was transfected with non functional sequence.The levels of miR 1283 expression were detected by fluorescence quantitative polymerase chain reaction at 24 hours after transfection.The cell proliferation was measured by 3-(4,5)-dimethylthiazol-2-yl-(2,5)-diphenyl tetrazolium bromide assay at 24,48 and 72 hours after transfection.Apoptosis was evaluated by propidium iodide staining and flow cytometry at 48 hours after transfection.Transwell experiments were performed to evaluate cellular invasion abilities at 24 hours after transfection.Analysis of variance and Bonferroni method were applied as statistical methods.Results The level of miR 1283 in as miR 1283 group was higher than that in the negative control group with statistically significant difference (14.85±0.57 vs 7.08±0.20,P＜0.01).At 24,48 and 72 hours after transfection,the inhibitory rate of cell proliferation in as-miR-1283 group was (8.04 ± 0.27) ％,(32.47 ± 0.24) ％ and (9.23± 0.17) ％,higher than those in the negative control group [(0.72 ± 0.06) ％,(1.17 ± 0.04) ％ and (0.53 ± 0.05) ％] (P ＜ 0.01,respectively).Cell apoptosis rate was higher in as-miR 1283 group than in negative control group [(16.33 ± 0.40) ％ vs (9.39± 0.58) ％,P＜0.01].The transmembrane cell number was lower in as-miR-1283 group as comparing with the negative control group (7.25 ± 1.83 vs 16.33 ± 2.08,P＜0.01).miR-1283 expression,apoptosis and transmembrane cell number in anti-miR-1283 group had no statistical difference as compared to the negative control group (all P ＞ 0.05).Conclusions Up-regulated levels of miR-1283 could inhibit HTR-8/SVneo cell proliferation and invasion,but promote the cell apoptosis.

Objective: To acquire recombinant nematode anticoagulant peptide ( NAP) with high anticoagulant activity. Methods: Pichia pastoris GS115 strain was transformed with recombinant yeast expression vector pPICS. 5K-rNAP. Expression of rNAP was induced with methanol after the identification of positive strains. NAP expressed in the collected yeast culture supernatant was confirmed with SDS-PAGE and Western blot. The biological activity of the products was validated with PT (prothrombin time) , INR (international normalized ratio) and APTT (activated partial thromboplastin time) , respectively. Results: The yeast strains expressing NAP were identified. The rNAP was secreted into culture supernatant with a molecular weight of about 10 kDa due to glycosylation, which is a little bigger than that predicted (8.7kDa). The anticoagulant efficiency of rNAP was confirmed with the in vitro assays. Conclusion: The recombinant nematode anticoagulant peptide with high biological activity was successfully expressed in Pichia pastoris and can be used in the future development of novel anticoagulant agent.
