BACKGROUND: Chinese traditional osteopathy is long in history, unique in manipulation and miraculous in therapeutic effect. But people understand it more m perception rather than in theory, more in application rather than in development. There is little research truly on the bioseience.OBJECTIVE: To probe into the macro-idea of Chinese traditional osteopathy, micro-mechanisms on characters and mathematics-physics models, aiming to provide new principles and approaches of treatment for the daily increased bone trauma, fracture and sport injury.SETTING: Physics and machine-electron college of a university, and its affiliated hospital.METHODS: Based on the natural concept of "integration between heaven and human being" and new concept of holistic medicine in Chinese traditional osteopathy, the macro-idea and characters of reduction and union of fracture are generalized from the characters of natural therapy and the biomechanical mechanisms and characters of reduction and union of fracture are summarized from the micro-reaction of bone repair and union so as to discover biomechanical mechanisms and characters of reduction and union of fracture and further to set up biomechanical models and mathematics-physics expressions during the treatment.RESULTS: Chinese traditional osteopathy envelopes macro-idea of "initiative reduction-functional union" in fracture and micro-mechanism on "stress adaptability-functional adaptability" of bone repair and union.CONCLUSION: Chinese traditional osteopathy compiles with the natural,green and non-traumatic therapy in bio-natural law of bone repair and union and supports the theme of "high thought and high skill".

PURPOSE: Respiratory syncytial virus (RSV) is the most frequent cause of lower respiratory infections in infants and young children. Early detection allows quarantining of infected inpatients to prevent nosocomial transmission and to choose a treatment. To achieve rapid reporting, to facilitate prompt antiviral therapy, and to avoid unnecessary use of antibiotics, an easy, rapid diagnostic method for RSV is needed. We evaluated a lateral flow immunochromatography (RSV Respi-Strip test) and EIA (Enzyme immuno assay) compared to RT-PCR. METHODS: From April 2007 to March 2008, 112 consecutive respiratory specimens (nasopharyngeal aspirates, throat swabs, tracheal aspirates, sputum) from patients who were suffering from the clinical signs and symptoms of respiratory tract infection were enrolled in Busan. A total of 112 patients were tested with RSV Respi-Strip (Corio-BioConcept, Belgium), EIA, and RT-PCR at the same time. RESULTS: Of the 112 specimens tested, the number of children who showed positive results at RT-PCR and Respi-Strip were 45 and 42, respectively. The Respi-Strip rapid antigen test had a sensitivity of 88% and a specificity of 94%. The positive and negative predictive values were 90% and 92%, respectively. The agreement was 83%. CONCLUSION: In our study, the rapid antigen test had as much sensitivity as any method for detection of RSV. The test has many advantages such as easy performance, simple interpretation, and rapid results. If the rapid antigen test is widely applied in the clinical setting, the may be useful for diagnostic and epidemiological studies of RSV infection.

BACKGROUND: Neointimal hyperplasia, as the most important mechanism of restenosis after intracoronary artery stenting, its severity is closely correlated with the degree of local inflammatory reaction initiated by vasular injury during stenting procedure. So, we proceeded this study to determine whether inflammatory markers such as CD11b/CD18 (Mac-1) adehsion molecules of neutrophils, sICAM-1 (soluble intercellular adhesion molecule-1), ESR, and CRP increase or not in the peripheral circulation after coronary artery stenting, and whether there is any association between these findings and the degree of later restenosis. METHOD: 32 patients (chronic stable angina 4, unstable angina 17, acute myocardial infarction 11) underwent single vessel coronary artery stenting were enrolled in our study. Blood samples were obtained from peripheral vein just before coronary artery stenting and 48 hours thereafter. The degrees of CD11b/CD18 expression on the surface of neutrophils were analyzed by flow cytometry with monoclonal antibodies, and sICAM-1 by ELISA method. At each times, ESR and CRP were also measured. Follow-up coronary artery angiography was performed with QCA analysis at least 6 months later. We compared the each 48 hours values with the baseline (just before procedure) values. Percentage increments (as a ratio 48 hours values to baseline) of CD11b/CD18 expression, sICAM-1, ESR, and CRP levels were also compared with the results of follow-up QCA analysis. RESULTS: Restenosis (diameter stenosis > or = 50%) occurred in 6 patients (19%) at follow up angiography. 48 hours values of CD11b/CD18 expression, sICAM-1, ESR, and CRP were significantly elevated from the baseline values (each p values, CD11b : < 0.0001, CD18 : 0.01, sICAM-1 : < 0.0001, ESR : 0.005, and CRP : 0.001). The percentage increments of CD11b/CD18 expression were more elevated in restenosis group than nonrestenosis group (CD11b : 341+/-215%/74+/-95%, CD18 : 84+/-60%/17+/-37%, each p < 0.001, 0.001). There was some positive correlation between the percentage increments in the expression of CD11b and the late loss index at the follow up angiography (r=.43, p<0.05). CONCLUSIONS: Through this study, we found that the activation of neutrophils was occurred, and that sICAM-1 level was increased after coronary artery stenting in the peripheral blood. There was some correlations between the degree of CD11b expression on the surface of neutrophils and the severity of late lumen loss of inserted stents. The measurements of increased neutrophil adhesion molecules of CD11b/CD18 levels at 48hrs after coronary stenting may have a value as the predictor of subsequent late restenosis.

Objective:To summarize and compare the characteristics of oral microbiota in women during the preconception period and the third trimester.Methods:This retrospective cohort study involved 55 women who were recruited in the Preconceptional Offspring Trajectory Study (PLOTS) conducted by Fudan University and followed up to the third trimester in the Maternal and Child Health Care Hospital of Jiading District of Shanghai from September 2016 to December 2019. A total of 110 unstimulated saliva samples were collected in the preconception period ( n=55) and the third trimester ( n=55). Features of oral microbiota in the samples were analyzed by 16S rRNA gene-based sequencing. Moreover, the related factors were also analyzed. Paired t test or Wilcoxon matched-pairs signed-ranks test were used to analyze the differences in α-diversity during preconception and the third trimester; t test, analysis of variance (ANOVA), Kruskal-Wallis test and Mann-Whitney U test for comparison between groups with different characteristics and permutational multivariate analysis of variance (PerMANOVA) for β-diversity were used; Linear discriminant analysis (LDA) effect size (LEfSe 1.0) was used to identify the iconic oral flora. Results:(1) The Ace index of oral microbiota was significantly lower in the third trimester than that in the preconception period [661.14(578.15-752.85) vs 730.64 (632.40-911.00), T=1 077.00, P=0.010]. There was also a significance difference in β-diversity ( F=12.539, R2=0.104, P=0.001). Some species such as Saccharibacteria_TM7_G3, Prevotella_7, Absconditabacteria_SR1_G1, Porphyromonas, Ruminococcaceae_UCG_014, Prevotella, Peptostreptococcus, Prevotella_2, Alloprevotella, Parvimonas, Solobacterium and Eubacterium_nodatum_group in saliva were statistically more abundant in the third trimester than those in the preconception period (all P<0.05). (2) The third-trimester Shannon index was lower among those with lower income [5.44 (5.08-5.77) vs 5.75 (5.44-6.12), U=219.00, P=0.029] and those with gargle habit after meal or dessert [5.36 (4.91-5.48) vs 5.72 (5.44-6.05), U=374.00, P=0.046]. Conclusions:The features of oral microbiota vary in women during the preconception period and the third trimester. There is a significant increase in the abundance of oral pathogenic and opportunistic bacteria in the third trimester.

PURPOSE: A variety of biodegradable polymers have been utilized to fabricate matrices for engineering genitourinary tissues, Chitosan is a biosynthetic polysaccharide that is the deacetylated derivative of chitin. The aims were to investigate the characteristics of the newly developed porous chitosan-based biodegradable scaffolds and to reconstruct cavernosal smooth muscle structure in vivo. MATERIALS AND METHODS: To study the cytotoxicity of the newly developed scaffolds, cultured L929 murine fibroblasts were stained with PKH-26 and then cultured on culture plate or loaded in chitosan/hyaluronic acid polymers. For in vivo study, human corpus cavernosal smooth muscle cells were seeded on the scaffolds at concentration of 20*106 cells per cm3 .A total of 24 polymer scaffolds were implanted subcutaneously with cells in one side and without cells in the other side, respectively, in 12 athymic mice, Mice were scarificed 7, 14, 28 days after implantation, respectively. H-E stain and monoclonal anti-alpha smooth muscle actin stain were performed. RESULTS: Scanning electron micrographs of chitosan and 0.03% hyaluronic acid based scaffolds showed sheet-like porous structure. The cell division numbers of L929 murine fibroblasts sere significantly increased in scaffolds by chitosan/hyaluronic acid compared with chitosan alone, Histologically the retrieved polymers seeded with cavernosal smooth muscle cells showed organized smooth muscle structure 28 days after implantation. immunohistochemical analysis confirmed the smooth muscle phenotype. CONCLUSION: These results show that porous chitosan-based biodegradable scaffolds are new biomaterials for the reconstruction of cavernosal smooth muscle structure. However, further studies are needed to make cavernosal sinusoidal structure using this new scaffolds.

OBJECTIVETo estimate prevalence of HIV/AIDS among children and the transmission routes in a highly endemic villages of AIDS.
METHODSTotally 208 high-risk women of child bearing age and 159 of their children aged 0 - 14 years were investigated. Their medical histories of blood donation or transfusion were collected, blood samples were taken and sera were separated for HIV test. Enzyme-linked immunosorbent assay (ELISA) and Western blot assay were performed for HIV antibody. The Nested-polymerase chain reaction (PCR) assay amplifying gag gene p17 was performed on samples of children aged less than 18 months.
RESULTSThirty-seven HIV infected cases were found among 159 children aged 0 - 14 years of whom 33 were infected by mother-to-child transmission (89.2%, 33/37), 3 by blood transfusion (8.1%, 3/37) and one by iatrogenic route (2.7%, 1/37). Sixty seven mothers who were seropositive for HIV and their 86 children who were born after 1992 were investigated, 33 cases of them were infected with HIV. The rate of vertical transmission was 38.4% (33/86). The HIV vertical transmission rate among mothers with AIDS (68.8%, 22/32) was significantly greater than that among mothers with asymptomatic HIV infection (20.4%, 11/54, P < 0.05). The number of children infected with HIV through vertical transmission increased from 1993 to 2001. Among 37 children infected with HIV, 12 cases developed AIDS and 4 of them died, of whom 2 cases died from tuberculosis. The morbidity of AIDS was 27.3% (9/33). Ninety three point nine percent (31/33) of infected mothers didn't know their HIV seropositive status before pregnancy and delivery. Of 8 pregnant women infected with HIV, one had aggravation of AIDS, 2 miscarried, 2 terminated their pregnancy and 3 continued their pregnancy.
CONCLUSIONMother-to-child transmission of HIV was the major route of HIV/AIDS transmission to the children. The main reason leading to HIV infection in children was the lack of prenatal HIV counseling and testing for the high-risk women of childbearing age and lake of interventions. The countermeasures must be taken to control the further transmission of AIDS in order to protect the health of women and children in the highly endemic areas of AIDS.

PURPOSE: To report two cases of temporary severe neurogenic blepharoptosis after successful reconstruction of orbital medial wall fracture. CASE SUMMARY: A 36-year-old woman and a 52-year-old man received orbital medial wall reconstruction with Medpor(R) for large fractures. Before the operation, the patients had only moderate swelling of the lid and periorbital ecchymosis. There were no limitations of extraocular muscles or ptosis. The operations were successful, although the patients developed unilateral complete ptosis with totally impaired levetor muscle function immediately after recovering from anesthesia. There were no anisocoria or limitations of the extraocular muscles. After oral steroid therapy, the patients began to improve on postoperative day 4 and after one month, respectively, and recovered to normal lid height and levator function after two months. CONCLUSIONS: Blepharoptosis after orbital medial wall reconstruction may result from ischemic damage at the end of the superior branch of the oculomotor nerve in the orbit due to compressive and tractional manipulation. Although very rare and temporary, this complication should be considered important because the occurrence can be unpredictable and may cause dissatisfaction to the surgeon and the patient after a successful operation.

The pregnancy-associated breast cancer is one of the most common malignancy developed during pregnant period and occupies 1-2% of the all breast cancer patients. There is no evidence to implicate pregnancy or lactation in either the etiology and the progression of breast cancer. Careful breast examination early in the pregnancy is very important to find solid masses before breast engorgement hides them. But unfortunately, delay in the diagnosis is common and most of patients with operable primary lesions have positive axillary lymph nodes. The treatment of choice is the modified radical mastectomy and adjuvant chemotherapy. The authors report a patient of breast cancer diagnosed and treated during pregnancy with review of literature.
