Hedysari polysaccharide (HPS) is the main component of hedysarum polybotrys. HPS can inhibit tumor cell proliferation, block the cell cycle in the G2-M period, modulate apoptosis via the mitochon drial pathway, and improve the red blood cell innate immunity and T lymphocyte immune function. HPS can relieve low immunity caused by chemotherapeutics.HPS plays anti-tumor effects by these ways mentioned above.

Objective To investigate the suitable mode of induced termination of pregnancy at second trimester for women with scarred uterus.Methods A retrospective study was performed in 120 cases of second trimester pregnant women with scarred uterus,who requested termination of pregnancy in Department of Obstetrics,Ruijin Hospital of Shanghai Jiaotong University from January 2010 to July 2016.The indications of termination of pregnancy were fetal anomaly,serious pregnant complication,intrauterine fetal deaths and personal factors.The interval time of previous operation to this pregnancy were recorded.It was ＜ 2 years in 35 cases and ≥2 years in 85 cases.The patients with normal hepatic function began to take mifepristone combined with ethacridine lactate (group A,62 cases).The method of mifepristone combined with misoprostol was used in the patients who failed to amniotomy to inject ethacridine lactatebecause of oligohydramnios or small gestational age (group B,58 cases).The detail information of every patient was recorded,including age,gestational weeks,gravidity,parity,the mode of previous operation,previous operation time and indication,the mode of induced labor inthis pregnancy,the interval time from administration to uterine contraction,delivery or not and the interval time from induction to delivery,postpartum hemorrhage,the successful rate of induce labor,and placental retention ratio.Results (1) It had no significant difference between groups A and B in age,gravidity,parity and the interval time of previous operation to this pregnancy (P ＞ 0.05).There was significant difference between two groups in gestational weeks of induction (P ＜0.01).(2) It had no significant difference between two groups in successful rate of induction and postpartum hemorrhage (P ＞ 0.05),but the time from induction to regular uterine contractionand delivery in group B was significant shorter than that of group A (P ＜ 0.01).The rate of delivery with 24 hours in group B was 89.66％.It was significant higher than that of group A (22.58％,P ＜0.01).(3) The rate of retained placenta in group A (19.23％,10/52) was significant lower than group B (4g.7g％,20/41),but the ratio of residual of placenta and membranes in group A (75％,39/52) was significant higher than that of group B (48.78％,20/41).It was no significant difference between the over 2 years group and the less 2 years group in the incidence rate of complications including placental retention,residual of placenta and membranes and postpartum hemorrhage.It had no significant difference between two groups in incidence of severe pain (P ＞ 0.05).Conclusions Both of methods of mifepristone combined with misoprostol and the mifepristone combined with ethacridine lactate are feasible to induce second trimester termination of pregnancy for women with scarred uterus.

Inflammation refers to the defensive reaction of living organisms with vascular systems against damage factors, and gets involved in the pathogenesis of many diseases. Uygur medicine is an important component of traditional Chinese medicine, as well as one of the four major ethnic medicines. It is widely applied in the clinical treatment of inflammatory diseases. In recent years, many domestic and foreign scholars have studied the anti-inflammatory effect and mechanism of effective components, effective fractions, extracts and compound preparations of Uygur medicine. In this paper, the authors summarized anti-inflammatory Uygur medicine, in the expectation of providing reference for discovering new anti-inflammatory drugs from Uygur medicine.

[Objective] To approach the causes and managements of dislocation after total hip arthroplasty.[Methods]850 total hip arthroplasties were done in our department from 1996 to 2004,in which 7 cases experienced post-operative dislocation.Whith 4 males and 3 females,the average age was 67 years old.Causes and managements have been studied retrospectively through analysis of history,surgical approach,timing and direction of the dislocations and predisposing factors of the dislocations occurred.[Results]There wer 7 cases of dislocations of which 5 patients(71%)were primary cases and 2 patients(29%)were revision cases;4 patients(57%)had history of hip surgery;1 case had mental disorder after cerebral surgery.Direct lateral approach was used for all these patients,and only anterior dislocation was occurred in this group.Through study the AP X-rays postoperatively,the abduction angle were more than 55 degree in 2 of these cases.The time of dislocation was from right after operation to 27 months after operation;5 of them experienced their dislocation within 3 months after operation.Closed reduction and 6 weeks traction were selected for all these patients,and 6 of them were successful.Recurrent dislccation occurred twice in another one patient within 3 months after reduction,and the acetabular cup was loosened during closed reduction.A stable joint was achieved after revision and modifying the abduction angle of the cup.[Conclusion]Causative risk factors for dislocation after total hip arthroplasty include surgery history on the same hip,inability to comply with instructions of rehabilitation,approach of surgery and malposition of the prosthesis.Closed reduction and traction for 6-week afterwards are usually successful for most of the dislocated cases.Revision could be done in the base of analyzing the reasons for recurrent dislocation,and then stale joint could be achieved.

Background Optic neuritis is one of the common clinical neuro-ophthalmic diseases.Recurrent optic neuritis can cause irreversible axonal damage and visual impairment,and no prevention method is effective up to now.Its pathogenesis is considered to be associated with the body's immune imbalance.Objective This proposal tried to establish experimental autoimmune encephalomyelitis (EAE) and explore the immunomodulatory effects of T helper (Treg),Th17 cell in the model of optic neuritis.Make the immune mechanism of demyelinating optic neuritis clear.Methods EAE model was established to observe the clinical symptoms and visual electrophysiological changes of optical neuritis in mice;hematoxylin-eosin staining to observe the histological changes in the mouse models of EAE; immunohistochemical staining to detect optic nerve axon damage markers β-amyloid peptide precurso (β-APP) protein expression quantity changes;reverse transcription PCR (RT-PCR) to detect the dynamic expression of forkhead/winged helix transcription factor p3 (Foxp3),transforming growth factor-β (TGF-β),interleukin-1β (IL-1β),IL-17,IL-10 in optic nerve tissue.Results After immunization 11 days,neurological symptoms of EAE mice started to appear,hematoxylin-eosin staining showed optic nerve tissue infiltration of inflammatory cytokines; immunohistochemical staining showed enhancement of axonal injury markers β-APP positive staining; flash visual evoked potential(F-VEP) test showed 7,11,14,19,23,28 days,compared with the normal mice,P1 prepatents of model group were prolonged after modeling,the differences were statistically significant (t =4.487,15.203,16.364,11.540,11.959,16.163,all at P＜0.05).When 7 days after modeling,the difference of N1-P1 amplitude between normal group and model group was no statistical significance (t =-0.992,P =0.378); while 11,14,19,23,28 days after modeling,compared with normal mice,N1-P1 amplitudes of model mice were significantly lower,the differences were statistically significant(all at P＜ 0.05).The expressions of TGF-β,IL-1β,IL-17,Foxp3,IL-10 mRNA among different time points had stastistie significant differences (F =12.721,15.015,14.343,69.374,68.290,all at P =0.000),compared with the normal group,when 11 days,14 days after modeling,TGF-β mRNA levels were significantly increased ; 19 days,23 days after modeling,IL-1β mRNA levels were significantly increased;7 days,11 days after modeling,IL-17 mRNA levels were significantly increased ;7,11,14,19,23,28 days after modeling,Foxp3 mRNA levels were significantly lower; 19,23,28 days after modeling,IL-10 mRNA levels were significantly lower,the difference were statistically significant (all at P＜ 0.05).Conclusions Th17 cells launch demyelinating optic neuritis immune injury,and Th1 subgroup performs the function of maintaining inflammatory lesions,Treg cell subgroup is abnormal much earlier than that of the Th2 subgroup.The imbalance of Th17/Treg cell may be involved in the pathogenesis of demyelinating optic neuritis.
