OBJECTIVETo evaluate the status of cell differentiation in nasal NK/T cell lymphomas.

METHODSThe clinical data of 88 cases of NK/T cell lymphomas were collected. Antibodies to the following antigens were used in the immunohistochemical study: T cell differentiation antigens (CD3epsilon, CD5 and CD1a); NK cell associated antigens (CD56, CD57) and antibodies of CD34 and CD38.

RESULTS(1) Clinicopathology: clinically, frequently involved sites were the nasal cavity and the pharynx. Ulceration and erosion of the mucosa were common signs. Pathologically, diffuse infiltration of the tumor cells was observed in 68 of 88 (70.45%) cases of nasal NK/T cell lymphomas. In 71 (80.68%) cases infiltrated cells were predominantly medium to large sized; (2) Differentiation status of tumor cells: the tumor cells expressed CD3epsilon in 78/88 (88.64%); CD5 in 56/88 (63.63%), CD56 in 25/88 (28.41%) and no positivity for CD1a, CD57, CD34 and CD38.

CONCLUSIONStatus of tumor cell differentiation in nasal NK/T cell lymphoma may have passed the stage of progenitor cell differentiation but not yet to the stage of mature T or NK cells.

Objective To study the long-term effect of meridian exercises on life qualities of stoke patients. Methods A total of 200 stroke patients were divided in to two groups according to course of disease, test group (100 cases) and control group (100 cases). Meridian exercises on special points were done everyday along with the basic conventional care in stable condition after 48 hours, lasting 6 months. ADL( Activities of Daily Living Scale) and HAMD(Hamilton Depression Rating Scale)were tested, scores between test group and control group before and after treatment were compared. Results Stroke patients in test group had better mental station, self-care abilities and social adaptabilities than control group. (P < 0. 05). Conclusions Meridian exercises in early treatment could develop the physical, mental and social function of stroke patients and significantly improve the long-term prognosis.

Objective To observe the effect of ear acupuncture point treatment for insomnia patients of kidney deficiency. Methods A total of 91 cases of insomnia patients with kidney deficiency were randomly divided into two groups: 46 cases of treatment group and 45 cases of control group. Patients in treatment group underwent ear acupuncture point treatment for 1 months, two ears in turn, three days changed. While patients in control group only used warm water treatment. Results The effective rate of treatment group was significantly higher than that in control group ( P < 0. 01). Except for sleeping efficiency and daytime function factor of PSQI factor score, the other score in treatment group was significantly lower than that in control group (P < 0. 05). The SAS score of treatment group had significant difference, (P <0. 01). There was no significant difference in terms of the rate of adverse effect between groups (P >0. 05); The positive symptom of anxiety and depression in treatment group was significantly lower than that in control group. Conclusions The effect of ear acupuncture point treatment can improve sleep quality and psychological health of patients of kidney deficiency, its uncomfortable rates has no significant difference compared with that in hot water footbath therapy.

OBJECTIVETo detect changes of Foxp3 expression in the decidua in patients with preeclampsia and investigate the correlation of Foxp3-924 (rs2232365) polymorphisms with preeclampsia.

METHODSFrom October 2011 to December 2012, 252 normal pregnant women and 156 preeclampsia patients of Han nationality from the same geographic region were tested for Foxp3-924 genotypes by polymerase chain reaction with sequence-specific primer (PCR-SSP). Sixty-eight of the patients with preeclampsia (33 with mild and 35 with severe preeclampsia) and 30 of the normal pregnant women were also examined for Foxp3 expression in the decidua using immunohistochemical method.

RESULTSFoxp3 positive expression rates in the decidua was 51.52% in mild preeclampsia and 28.57% in severe preeclampsia cases, significantly lower than that in the control group (86.67%, P<0.05). In preeclampsia patients, the frequencies of Foxp3-924G/G, G/A, and A/A genotypes were 0.1346, 0.4615 and 0.4038, respectively, and the frequencies of Foxp3-924A and Foxp3-924 G were 0.6346 and 0.3654, respectively. The genotype frequencies of Foxp3-924G/G, G/A and A/A in the control group were 0.1508, 0.4087 and 0.4405, respectively, and the frequencies of Foxp3-924 A and Foxp3-924 G were 0.6448 and 0.3552, respectively. No significant differences were found in the gene frequencies of Foxp3-924G/A between preeclampsia patients and the control group (P>0.05).

CONCLUSIONThe expression level of Foxp3 in the placental tissue of preeclampsia patients is significantly lower than that in normal pregnant women, suggesting that lowered Foxp3 expression decreases the immunosuppressive function and causes imbalance of immune tolerance between maternal-fetal to induce preeclampsia. Foxp3-924 polymorphisms is not significantly correlated with the occurrence of preeclampsia.

OBJECTIVETo investigate the clinical features of invasive fungal disease (IFD) in children without underlying diseases.

METHODSThe clinical data of 49 children without underlying diseases who were diagnosed with IFD were retrospectively studied.

RESULTSFungal pathogens were detected in 37 (76%) out of 49 patients, including Cryptococcus neoformans (17 children, 46%), Candida albicans (10 children, 27%), Aspergillus (3 children, 8%), and Candida parapsilosis (3 children, 8%). Fungal pneumonia (17 children, 46%) was the most commonly seen disease, with Candida albicans as the major pathogen (9 children, 53%). The 49 children had at least one high-risk factor for infection, including the use of antibiotics, a long length of hospital stay, and invasive procedures. Of all the children, 82% did not respond well to antibiotic treatment or experienced recurrent pyrexia. Among the 24 children who underwent G tests, 17 (71%) showed positive results. All the children were given antifungal therapy, and among these children, 37 (75%)were cured, 3 (6%) were still in the treatment, 5 (10%) died, and 4 (8%) were lost to follow-up.

CONCLUSIONSIn IFD children without underlying diseases, Cryptococcus neoformans and Candida are the main pathogens, and lung infection is the most common disease. Long-term use of high-dose antibiotics may be an important risk factor for fungal infection. The IFD children without underlying diseases are sensitive to antifungal drugs and have a satisfactory prognosis.

OBJECTIVETo analyze the therapeutic effect and the influencing factors of event-free survival (EFS) of childhood acute lymphoblastic leukemia (ALL) in Xiangya Hospital of Central South University and the First Affiliated Hospital of Guangxi Medical University.

METHODSAll the patients adopted chemotherapy according to therapeutic guideline revised by the Subspecialty Group of Hematology, The Society of Pediatrics, Chinese Medical Association for the second-time in 1998 (the Rongcheng ALL-98 Protocol). Kaplan-Meier method was used to estimate the survival rates of 188 patients who received therapy with good compliance. The differences of EFS between groups were assessed by Log-rank test. The independent influencing factors on EFS were analyzed by the Cox proportional hazards regression model.

RESULTSAfter receiving inductive treatment, 354 of 374 (93.6%) patients demonstrated a complete remission; 188 patients who received complete courses of treatment with good compliance showed (68.1 +/- 5.6)% five-year EFS. Meanwhile, the five-year EFS in standard-risk (SR) group and high-risk (HR) group were (75.2 +/- 6.0)% and (47.6 +/- 11.6)%, respectively. The total relapse rate was 10.6% and the median time to relapse was 13 months. Twenty-nine of 188 patients (15.4%) were dead, and 13 patients (7.0%) died from treatment-related complications. Independent adverse prognostic factors included risk grouping, t (9; 22)/bcr-abl gene and leukocyte count.

CONCLUSIONSThe total EFS of childhood ALL patients treated with Rongcheng ALL-98 Protocol in two hospitals was close to 70%. Therefore, it is necessary to evaluate risk factors and consider the grouping in more detail to reduce the treatment-related mortality and to increase the compliance of treatment which can ultimately improve the EFS.

OBJECTIVETo study the relationship between nasal carriage and Staphylococcus aureus (S. aureus) infection in hospitalized children.

METHODSFifty-six hospitalized children infected with S. aureus were recruited in this study. Nasal swabs were collected and cultured, and the nasal carriage rate of S. aureus was examined. PVL virulence gene and mecA resistance gene were both detected in clinical strains and nasal carriage strains by PCR.

RESULTSTwenty-two (39%) of the 56 children had nasal carriage of S. aureus, and most of them (18 cases) were younger than one year. Among these 22 children, 11 (50%) had previous hospitalization over the past year. In the infected strains, the rate of methicillin-resistant S. aureus (MRSA) was 29% (16/56), while it was 32% (7/22) in carriage strains. The mecA positive results in clinical strains were consistent with the results in nasal carriage strains. Among 5 PVL-positive nasal carriage strains, 4 (90%) could be matched with their clinical strains, all of which were MRSA.

CONCLUSIONSNasal carriage is a potential risk factor for S. aureus infection. Nosocomial transmission may lead to nasal carriage, which can cause S. aureus infection. The isolation rate of MRSA is high in hospitalized children infected with S. aureus, which implies that more attention is needed for this situation. The isolates from noses may be clonally identical to the isolates from clinical secretions, and the homology between them needs to be confirmed by multi-locus sequence typing.

Membrane-type 1 matrix metalloproteinase (MT1 MMP/MMP 14) plays crucial roles in tumor cell growth, invasion, and angiogenesis. To clarify whether the endogenously expressed MT1-MMP in metastatic human ovarian carcinoma cell lines SKOV3 plays a critical role in tumor cell invasiveness, antisense MT1-MMP cloned in eukaryotic expression vector pMMP14as was transferred into SKOV3 cells. 48h after transfection, decreased expression of endogenous MT1-MMP protein was detected in pMMP14as transfected SKOV3 cells and the activation of pro MMP2was inhibited markedly. The mean percentage of invasive cells was (62. 50 ±5. 30) % in pMMP14as-transfected cells, which was obviously less than that (97.20±6.90) % in the control.Thus, antisense MT1 MMP effectively inhibited the endogenous MT1 MMP expression and the invasiveness in SKOV3 cells, suggesting that MT1-MMP may be a therapeutic target molecule for human invasive ovarian cancers.
