Objective To analyze the therapeutic effect and prognosis according to a new CT classification of traumatic posterior occipital epidural hematomas (POEH). Methods We classified the CT presentation of 104 patients with POEH by sinus transverses: type Ⅰ hematomas were defined as up-sinus transverses; type Ⅱ hematomas were defined as sub-sinus transverses and type Ⅲ hematomas were defined as straddling sinus transverses. The above types were divided into unilateral or bilateral subtypes. Bone flap craniotomy through a median posterior approach was performed in patients with unilateral hematoma adjacent to the midline. Bone flap craniotomy through a median suboccipital approach was adopted for patients with bilateral middle occipital hematoma. Results Type Ⅰ enjoyed mild symptoms, good curative effect and low mortality rate (7%). Type Ⅱ and Ⅲ had serious symptoms and high mortality rate (13.3%, 16.6%, respectively). Conclusion The classification of the CT presentation of POEH is helpful in confirming the diagnosis, drawing up the scheme of treatment and judging the prognosis.

OBJECTIVETo identify the relationship between coagulation factor V (FV) gene single nucleotide polymorphisms (SNPs) and venous thromboembolism (VTE).

METHODSThe FV clotting activity (FV: C) and FV antigen (FV: Ag) in plasma of VTE group (111 patients) and normal control (110 patients) were detected using one-stage clotting assay and ELISA, respectively. Five pairs of primers of the F V polymorphisms including Asp79His, Arg306The, Arg306Gly, Arg506Gln and Ile359The/His1299 Arg were synthesized and amplified by PCR. The PCR products were digested by restriction enzyme using PCR-RFLP. The detected polymorphisms were confirmed by direct sequencing. The samples containing the polymorphisms were screened for coding regions of all F V exons with direct sequencing.

RESULTSThe plasma levels of F V: C and F V: Ag of VTE group and normal control were (106.9 +/- 28.0)%, (110.4 +/- 33.3)% and (102.4 +/- 30.9)%, (102.1 +/- 24.1)%, respectively. The plasma level of FV: Ag was significantly different between VTE group and normal control. However, there was no difference in F V: C levels. Polymorphisms for the fore mentioned 5 primer pairs were not found in either patients or normal controls. Polymorphism of His1299Arg was identified in 5 patients with VTE and 3 normal controls. And these 5 cases also combined Met1736Val polymorphism, 3 of them combined another Asp2194Gly polymorphism.

CONCLUSIONThe higher plasma level of F V: Ag contribute to venous thromboembolism. There is no relationship between polymorphisms of Asp79His, Arg306The, Arg306Gly, Arg506Gln, Ile359The and venous thromboembolism in Chinese studied. Polymorphism His1299Arg is higher in VTE group than in normal control, but has no statistical difference. Polymorphisms of His1299Arg, Met1736Val and Asp2194Gly are linked disequilibrium in Chinese Han population.

OBJECTIVETo observe the therapeutic effect of Yishen Qingre Huashi Recipe (YQHR) in treating proteinuria of chronic glomerular disease patients with Pi-Shen deficiency complicated damp-heat syndrome (PSDCDHS).

METHODSTotally 121 stage 1 -2 primary chronic glomerular disease patients with PSDCDHS were randomly assigned to the treated group (85 cases) and the control group (36 cases) according to 2:1. All patients received conventional and symptomatic treatment. Patients in the treated group took YQHR additionally, while those in the control group took Losartan Potassium Tablet (50 mg each time, once per day) additionally. The therapeutic course for all was 6 months. Changes of 24 h urine protein, blood urea nitrogen (BUN), serum creatinine(SCr), and estimated glomerular filtration rate (eGFR) were observed at different time points. And the difference in therapeutic effects were compared between the two groups.

RESULTSCompared with the control group after 6 months of treatment, 24 h urine protein obviously decreased in the treated group (P <0. 05). There was no statistical difference in SCr, BUN, or eGFR between the two groups after 6 months of treatment (P >0. 05). The total effective rate after 2, 4, and 6 months of treatment in the treated group was 77. 6% (66/85 cases), 82. 4% (70/85 cases), and 89. 4% (76/85 cases), respectively. They were 47. 2% (17/36 cases), 55. 6% (20/36 cases), and 61. 1% (22/36 cases) in the control group, respectively. Compared with before treatment in the treated group, the total effective effect after 6 months of treatment was higher than that after 2 months of treatment (χ2=4. 28, P <0. 01). Compared with the control group at the same time points, the total effective rate in the treated group after 2, 4, and 6 months of treatment was higher (χ2=10. 87, 9. 53, 13.16, P <0. 01).

CONCLUSIONYQHR could significantly lower proteinuria in chronic glomerular disease patients with PSDCDHS, improve the clinical effect, thereby providing clinical evidence for treating chronic glomerular disease proteinuria from resolving dampness and clearing heat.

OBJECTIVETo establish a mice model with selective inactivation adenosine A2A receptors (A2ARs) in peripheral white blood cells (PWBC).

METHODSA2ARs were selectively inactivated in PWBCs by transplanting bone marrow cells (BMCs) from A2AR knockout (KO) mice into their wild type (WT) littermates after a single total body irradiation of 9.5 Gy or fractionated total body irradiation of 6.2 Gy x 2. The efficiency of reconstitution of bone marrow-derived cells in chimeric mice was assessed.

RESULTSPCR band patterns changed from the recipient pattern (one band of 330 bp) to the donor (two bands of 300 and 330 bp) pattern. Immunohistochemistry analysis showed that 10.21% of cells were A2AR+ in PWBCs in KO--> WT mice, whereas 96.72% of cells were A2AR+ in WT mice. The survival rates of mice irradiated with 6.2 Gy x 2 and transplanted with more than 6 x 10(6) BMCs were about 91%.

CONCLUSIONA murine model of selective inactivation adenosine A2A receptors in PWBCs was established successfully.

Recently, activation of the adenosine A2A receptors has been shown to exert protection against peripheral tissue injuries but aggravation in the central nervous system (CNS) injuries. To explore the different effects of adenosine A2A receptors and try to perform some new treatment strategies for peripheral tissue and CNS traumas, we constructed the mouse models of skin trauma, skin combined radiation-impaired wound and traumatic brain injury (TBI), respectively. Wild type mice and A2A receptor gene knockout mice were both used in the experiments. In skin trauma and combined radiation-impaired wound models, the time of wound healing was observed, while in TBI model, neurological deficit scores, water content in injured brain and glutamate concentration in cerebral spinal fluid (CSF) were detected at 24 h after TBI. The results showed that in skin trauma and combined radiation-impaired wound models, CGS21680 (an agonist of the A2A receptors) promoted while A2A receptor gene knockout delayed the course of skin wound healing. On the contrary, in TBI model, A2A receptor gene knockout, not CGS21680, showed a protective role by inhibition of glutamate release. These data further indicate that promoting glutamate release may account for the different effects of A2A receptor activation in CNS injury and peripheral tissue injury models. These findings may provide some experimental evidence and a new strategy for clinical treatment of peripheral tissue damages by agonists of A2A receptors, while treatment of CNS injuries by antagonists of A2A receptors.

OBJECTIVETo explore the prevalence of vision, mental, audibility, language, psychiatry, extremity, and influence factors in the 0 - 7 year olds.

METHODSA total number of 77,727 0 - 7 year old children living in Shenzhen city were tested with tree phase screening under the Chinese standard of evaluation in disabilities.

RESULTSThe prevalence of all disabilities was 5.59 per thousand (adjusted rate was 8.49 per thousand with a false negative of 3.1 per thousand ). The prevalence of mental disease was the highest (1.88 per thousand, with adjusted rate 3.43 per thousand ), the prevalence of language disability was 1.88 per thousand (including retarded language development, with adjusted rate 3.43 per thousand ). The prevalence rates of psychiatry, extremity and audibility disability were 1.59 per thousand, 1.56 per thousand, 1.11 per thousand respectively with of vision the lowest (0.37 per thousand ). The prevalence of all disabilities, audibility, language and mental was on the increase with age. The difference was statistically significant. Among all different age groups regarding psychiatric disease, the highest fell in the 2 - 4 year olds. The prevalence of extremity was not statistically different among age groups. The suspected agents of disease which occurred before or during pregnancy took up 45.7%.

CONCLUSIONThe prevalence of six kinds disabilities in Shenzhen was about 10 per thousand lower than that of the samples of the nation in 1989, but two times higher than that of similar studies in Japan. The prevalence rates of language and psychiatric disease were higher than that of the nation in 1989. The causation should be further studied.
