To characterize the CD45RA+and CD45RO+T lymphocyte subsets in the peripheral blood of patients with cGVHD induced by allogeneic haematopoietic stem cell transplantation ( allo-HSCT ) and to explore their relations with the disease.Methods:The peripheral blood was collected from 64 patients after allo-HSCT,including 21 non-cGVHD patients,15 light grade cGVHD patients,18 mild grade cGVHD patients and 10 severe grade cGVHD patients,then CD4+CD45RA+,CD4+CD45RO+, CD8+CD45RA+and CD8+CD45RO+T lymphocyte subsets were detected by flow cytometry ( FCM).Results: Compared with the control,the percent of CD4+CD45RA+T lymphocyte in patients with light,mild and severe grade cGVHD decreased markedly (P<0.05),the percent of CD4+CD45RO+T lymphocyte increased markedly (P<0.05).But there were not obviously change in the patient with different grade cGVHD.The percent of CD8+CD45RA+,CD8+CD45RO+T lymphocyte did not change obviously.Conclusion:CD4+CD45RA+and CD4+CD45RO+may play an important role in the pathogenesis of cGVHD.

Objective:To understand the management status of breast cancer-related lymphedema, and to provide a basis for the formulation of prevention and treatment plans for breast cancer-related lymphedema.Methods:Using accidental sampling, a questionnaire designed by the research team was used to survey nurses in 58 hospitals in Jiangsu Province.Results:This study surveyed a total of 58 hospitals, of which 53 were general hospitals and 5 specialized hospitals. Only 11 hospitals (18.97%) had treatment rooms dedicated to conservative treatment of lymphedema, 9 hospitals (15.52%) had opened lymphedema clinics, and 15 hospitals (25.86%) had professional international lymphedema therapists. All the 58 hospitals had different degrees of prevention and management of breast cancer-related lymphedema.Conclusions:The comprehensive management of lymphedema has not yet been achieved, and the management standards of lymphedema also need to be further improved. It is important to establish a unified and standardized management plan and practice standards.

Objective To evaluate the feasibility of MRI-guided vacuum-assisted breast biopsy in domestic clinical prac tice.Methods A total of 45 patients with 45 suspicious breast lesions were examined with MRI-guided vacuum assisted bi opsy.The complications were observed.And the followed-up was performed.Results In 45 suspected breast lesions,43 lesions (43/45,95.56％) were successfully sampled under MRI-guided vacuum-assisted biopsy and the pathologic diagnosis was obtained.For another 2 lesions (2/45,4.44％),the pathology diagnosis were not obtained.The time to perform MRI-guided biopsy was (45.87±8.41)min for one lesion.The 5 malignant lesions (5/45,11.11％) confirmed by biopsy pathology were consistent with postoperative pathological results.For the 38 benign lesions (38/45,84.44％) confirmed by biopsy pathology,there was no malignant performance found in MRI follow-up for 6 months.Because of successful MR imaging-guided core biopsy findings,the clinic treatments were changed in 14 patients (14/45,31.11％).Five cases (5/45,11.11％) with malignant tumors were diagnosed early.The surgical biopsy was avoided in 9 benign cases (9/45,20.00 ％) who suspected as malignant.In all 45 patients,no complications occurred,such as hematoma and infection.Con clusion MRI-Guided vacuum-assisted breast biopsy is sufficient and safe for obtaining histologic proof of lesions,and plays an important role in guiding clinic treatment of some lesions visible only by MRI.

Objective:To evaluate the effect of vacuum disk(VD) for non-invasive treatment of recurrent and acquired pectus excavatum(PE).Methods:From June 2017 to June 2019, 29 patients recruited from our outpatient clinic were included in this retrospective study and followed-up every 3 month according to the schedule. The patients were distributed into three groups(group 1 treated ≤6 months; group 2 treated from 6 months to 12 months; group 3 treated >12 months). The device should be applied regularly for more than 2 hours daily. The deformity chest wall was scanned by three-dimensional(3D)scanner at clinic, and the 3D-depth(3D-DE) and 3D-Haller index(3D-HI) of PE were calculated through Geomagic software.Results:In this cohort, 29 patients were eligible, 18 symmetrical PE and 11 asymmetric PE. The application time ranged from 3 months to 15 months(average 7.6 months). 4 paitents was lifted to a normal level, 23 patients were differently improved. However, 2 paitents had no improvement. The average of the depth and 3D-HI of all patients were improved from 17.7 mm to 11.6 mm and 1.739 to 1.598, respectively. It’s no statistically significant difference for the elevation of 3D-DE and 3D-HI between symmetrical and asymmetric PE( t=-2.821, P=0.558; t=0.074, P=0.068). When comparing the improvement of 3D-DE or 3D-HI of PE to the patient's treatment time, a statistically significant difference was proved between the group 2 and group 1( t=-2.261, P=0.014; t=-0.436, P=0.043), but not between the group 3 and group 2( t=-1.240, P=0.139; t=0.622, P=0.568). The main side effects include moderate subcutaneous hematoma(84%), petechial bleeding(27%), thoracalgia(32%) and chest tightness(17%), no other side effect appear till now. Conclusion:VD for treatment of recurrent and acquired PE is convenient, safe and noninvasive, which can be an alternative treatment for recurrent and acquired PE, However, long term of efficacy evaluation is still needed.

OBJECTIVETo study the effects of modified Huopo Xialing Decoction (HXD) in treating patients of Pi-Wei dampness-heat syndrome (PWDHS) and its impact on epithelial cell apoptosis of tongue.

METHODSFifty patients with PWDHD were randomized depending on their visiting sequence into two groups, the 30 patients in the treatment group treated with HXD and the 20 in the control group treated with Domperidone. The therapeutic course for both groups was 2 weeks. Besides, a normal control group consisting of 30 healthy volunteers was set up. The changes of tongue fur, grade of major syndromes in different groups were observed and scored before and after treatment to evaluate the therapeutic effectiveness, and the apoptotic index (AI) was estimated using TUNEL technique.

RESULTSAI in the two patient groups before treatment was obviously lower than that in the normal group (P < 0.01 or P < 0.05); after treatment, AI in the treatment group increased significantly (P < 0.01), with no difference from that in the normal group (P > 0.05), while in the control group, it only showed a slight trend of increasing. Similar outcome of tongue fur grades was seen in the two groups, it was improved significantly (P < 0.01) in the treatment group but insignificantly in the control group (P > 0.05). After treatment, syndrome scores were both lower in the two groups (P < 0.01), but the decrement in the treatment group was more significant than that in the control group (P < 0.01). Comparison between groups showed that the total effective rate in the treatment group was significantly superior to that in the control group (90% vs 65%, P < 0.01).

CONCLUSIONHXD has good clinical efficacy in treating PWDHS, and has good effect in alleviating the greasy yellow tongue fur in patients with PWDHS by accelerating the tongue epithelial cell apoptosis.

OBJECTIVETo investigate whether WASP/Verprolin homologous protein 1 (WAVE1) plays a role in the pathogenesis of childhood acute lymphoblastic leukemia (ALL).

METHODSWAVE1 mRNA and protein expression in bone marrow mononuclear cells (BMMCs) was measured by RT-PCR and Western blotting respectively in 4 children with ALL relapse, 15 children with ALL in complete remission (CR) and 40 children with newly diagnosed ALL. Ten normal bone marrow samples were used as controls. Jurkat cells were treated with different concentrations of adriamycin (ADM). The cell proliferation was detected with MTT. The apoptosis rate was measured by flow cytometry. WAVE1 mRNA and protein expression of Jurkat cells treated with ADM was detected by RT-PCR and Western blotting respectively.

RESULTSWAVE1 was not expressed or weakly expressed in BMMCs from normal controls and patients with ALL in CR. Higher WAVE1 mRNA and protein expression was found in BMMCs from patients with newly diagnosed ALL and patients with relapse ALL when compared with the controls and the patients in CR (P<0.01). ADM significantly inhibited the proliferation of the Jurkat cells and the inhibitory effect was dose-and time-dependent (P<0.05). After ADM treatment for 24 hrs, the percentage of apoptosis cells increased significantly and WAVE1 mRNA and protein expression of Jurkat cells decreased significantly when compared with the untreated controls (P<0.05).

CONCLUSIONSThe WAVE1 expression increased in children with ALL. WAVE1 may be related to the development of ALL and may be severed as a marker for the evaluation of the severity of ALL in children.
