Breast cancer should be considered as a family of diseases which are significantly different from each other in molecule level rather than a single disease, and clinical heterogeneity of breast cancer origins from molecular heterogeneity. Gene-expression signatures have been developed based on gene expression profiling of breast cancer, such as the 70-gene signature, 21 -gene signature and intrinsic subtypes of breast cancer. These signatures are valuable and have a good prospect in prognosis predicting and clinical decision of breast cancer.

Evidence-based medicine was applied in the clinic teaching and ward inspection of superficial bladder cancer as far as no consensus was reached on its treatment.Some preferred to total cystectomy while others favored transurethral resection of bladder tumor and bladder instillation.In order to solve this problem,evidence-based medicine was applied in our clinic teaching procedure.Students were asked to read relative papers and draw the final conclusions with evidence-based medicine.Clinical guidance was provided for the students to promote clinical application.

The service behavior of medical staff is influenced by the organizational environment and management mode of the hospital. That is to say, the organization and management determine the standardization and sustainability of a hospital's humanistic services, and organizational driving force is also an important factor for the staff to innovate their services. Organization and management of a hospital' s humanistic services is composed of three factors: service operation management, service elements management and service performance management. These factors ensure a hospital's humanistic services to achieve whole-staff-participation, sustainability and standardization.

Objective To investigate the effect of Treg cells and Th17 cells on the pathogenesis of SLE in patients with SLE,by detecting levels of serum IL-10 and IL-17 in patients with systemic lupus erythematosus (SLE).Methods Selected 54 patients with SLE diagnosed in Suzhou Municipal Hospital Affiliated to Nanjing Medical University from July 2013 to July 2015 as subjects,and 19 healthy persons were selected as control group.Using double antibody sandwich method (ELISA) to detect the levels of IL-10 and IL-17 in two groups.Using indirect immunofluorescence and western blot method to detect ANA,dsDNA,RNP,Sm,SSA and SSB in patients with SLE.Then compared and correlation analysed the level of IL-10 and IL-17,the levels of IL-10 and IL-17 in ANA,RNP,Sm,SSA and dsDNA groups were analyzed simultaneously.Results The level of IL-10 and IL-17 in SLE were 63.7±89.0 pg/ml and 87.7±123.0 pg/ml,and control group were 20.8±8.9 pg/ml and 18.5 ± 111.6 pg/ml,with the statistically significant difference (trL10 =3.484,tIL-17 =4.076,P＜0.01).The level of positive group in SLE were 176.5±93.2 pg/ml and 237.2±107.5 pg/ml,and negative group were 16.2±5.7 pg/ml and 12.9 ±8.3 pg/ml,with the statistically significant difference (tIL-10 =6.875,tIL-17 =8.843,P＜0.01).The level of IL-10 was positively correlated with IL-17 level in SLE (r=0.96,P＜0.05).The level of IL-10 and IL-17 in ANA high titer group were 91.8±100.8 pg/ml and 135.5±140.9 pg/ml,ANA low titer group were 44.5±76.7 pg/ml and 54.4±98.5 pg/ml,with the statistically significant difference (tIL10 =2.215,tIL-17 =2.345,P＜0.05).The level of IL-10 and IL-17 in anti ds-DNA antibody positive group were 87.1 ± 101.1 pg/ml and 122.4 ± 137.1 pg/ml,negative group were 27.4± 50.1 pg/ml and 28.6 ± 61.6 pg/ml,with the statistically significant difference (tIL-10 =2.904,tIL-17 =3.443,P＜0.05).Conclusion The levels of IL-10 and IL-17 were significantly increased and there was positive correlation.It was explained that the anti-inflammatory and pro-inflammatory response existing at the same time in SLE patients and Treg cell and Th17 cell may also play an important role in the occurrence and development in SLE.

BACKGROUND: Recently, a few studies have reported the correlation between transforming growth factor-α (TGF-α) and graft-versus-host disease (GVHD); however, the combination of TGF-α with other cytokines in patients with chronic or acute GVHD requires further study.OBJECTIVE: To analyze the changes of serum tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), and transforming growth factor-α (TGF-α) in leukemic patients after allogeneic hematopoietic stem cell transplantation (Allo-HSCT) and investigate the effects of these cytokines on different grades of GVHD.DESIGN: Case control study.SETTING: Department of Hematology, Organ Transplantation Center, the Second Affiliated Hospital, General Hospital of Chinese PLA; Department of Nuclear Medicine, the Second Affiliated Hospital, General Hospital of Chinese PLA.PARTICIPANTS: Forty-two leukemic patients (23 males and 19 females, 16-68 years old, mean age of 35 years) who underwent Allo-HSCT for the first time were selected from the Department of Hematology, Organ Transplantation Center, the Second Affiliated Hospital, General Hospital of Chinese PLA and Department of Transplantation, the 307 Hospital of Chinese PLA from June 2005 to June 2007. Twelve patients had acute granulocytic leukemia (AGL), fifteen patients had acute lymphocytic leukemia (ALL), and fifteen patients had chronic granulocytic leukemia (CGL). Among the 42 patients, 37 underwent peripheral blood transplantation and five received bone marrow transplantation. Twenty-one patients had acute GVHD (18 cases in grades Ⅰ-Ⅱ and three cases in grades Ⅲ-Ⅳ) after Allo-HSCT, but the other 21 patients did not. Fourteen patients had chronic GVHD (five cases of limited type and nine cases of extensive type), but the other 28 patients did not. An additional 30 healthy subjects (18 males and 12 females, 20-70 years old, mean age of 44 years) were collected as a normal control group. All patients provided confirmed consent, and the study was approved by the local ethics committee.METHODS: Levels of serum TNF-α, IL-4, and TGF-α in leukemic patients with Allo-HSCT and normal subjects were measured by radio-immuno-assay, the cytokines levels of the patients with/without acute GVHD, of those with/without chronic GVHD and of different grades of GVHD were compared.MAIN OUTCOME MEASURES: Comparisons of serum TNF-α, IL-4, and TGF-α among the groups.RESULTS: All 42 leukemic patients and 30 healthy subjects were included in the final analysis. Levels of TNF-α, IL-4, and TGF-α in patients with acute or chronic GVHD were significantly higher than those in the normal subjects (P<0.05-0.01). Levels of TNF-α and IL-4 in patients without acute GVHD were significantly higher than those in the normal subjects (P<0.01,0.05). Levels of TNF-α, IL-4, and TGF-α in patients with acute GVHD were significantly higher than those in patients without acute GVHD (P<0.05). Levels of TNF-α, IL-4, and TGF-α in patients with chronic GVHD were significantly higher than those in patients without chronic GVHD (P<0.05). Levels of serum TNF-α and TGF-α in patients with acute GVHD of grades Ⅲ-Ⅳ or chronic GVHD of extensive type were significantly higher than those in patients with acute GVHD of grades Ⅰ-Ⅱ or chronic GVHD of limited type (P<0.05-0.01).CONCLUSION: After Allo-HSCT, dynamically monitoring changes of levels of TNF-α, IL-4, and TGF-α may serve as a possible means of predicting the onset of acute or chronic GVHD and may contribute considerably to deciding clinical severity of GVHD.

To investigate the effects of Xuefu Zhuyu Oral Liquid, a compound traditional Chinese herbal medicine for resolving stagnation, on hemorheology in the patients with blood-stasis syndrome due to coronary disease and their relationship with human platelet antigen-3 (HPA-3) polymorphism of membrane glycoprotein IIb (GPIIb).

Objective To investigate the effects of electroacupuncture (EA) on the implementation of blind nasojejunal (NJ) tube placement and enteral nutrition (EN) in neurosurgical severe coma patients in intensive care unit (ICU).Methods Seventy-nine neurosurgical severe coma patients admitted to ICU were randomly divided into conventional group (blind NJ tube placement,n =40) and EA group (NJ placement and EA,n =39).EA was performed after NJ tube placement at bilateral acupoints Zusanli (ST36) and Hegu (L14) points using EA treatment instrument.The impelling distance of NJ tube were measured and the success rate of NJ tube placement were calculated.The postoperative complications were observed.Results The difference of NJ tube impelling distances at the 24th,48th,and 72th hours after surgery in EA group were significant longer than that in conventional group (P ＜ 0.05).The success rates of NJ tube placement at the 24th and 72nd hours after surgery in EA group were significantly better than that in conventional group (P ＜ 0.05).Their EN calories qualifiedness rate in 72 hours also increased significantly compared with conventional group and the proportion of patients assisted with parenteral nutrition decreased (P ＜0.05).The postoperative complications including alimentary tract hemorrhage,vomiting,and abdominal distension decreased remarkably in EA group compared with conventional group (P ＜ 0.05).Conclusions EA stimulation at acupoints could promote the gastrointestinal peristalsis of neurosurgical severe coma patients and elevate the success rate of blind NJ tube placement,so it is beneficial for the implementation of early enteral nutrition (EEN).

Objective To evaluate the clinical effects of medial patellofemoral ligament reconstruction using the semitendinosus tendon autograft for the treatment of the patellar dislocation.Methods From January 2007 to January 2010,16 cases of patellar dislocation were included in this group.Lysholm score was averaged preoperatively.Arthroscopic-assisted in the semitendinosus tendon autograft reconstruction of the medial patellofemoral ligament,the central graft were fixed on the inner edge of the patellar in the upper 1/3 and the mid-point location,the end were fixed on the channel of femoral epicondyle and adductor tubercle.Results All the patients that lined progressive knee rehabilitation after operation,returned to normal walking for 3 months,6 months could be sports.Followed up for 7-54( 26.36 ± 20.48 ) months,all of patients incision were healed as grade Ⅰ,knee function were normal.Postoperative Lysholm score (93.21 ± 4.68) scores compared with preoperative ( 76.53 ± 8.35 ) scores was significant difference (P ＜ 0.05 ).Conclusions Using the semitendinosus tendon autograft for the treatment of the patellar dislocation method is simple and can effectively restore normal patellar trajectory.At the same time,which is an effective surgical method to treat recurrentdislocation of the patellar.
