OBJECTIVETo analyze effects of fracture of processus styloideus ulnae on prognosis in the treatment of distal radial fracture of type C according to AO classification.

METHODSThis was a retrospective case-control study, and the information was got ten through case evaluation and follow-up, including sex, age, patient satisfaction, Gartland & Werley score and radiographic score. There were 76 patient treated with open reduction and plate fixation in People's Hospital Affiliated to Peking University from July 2006 to July 2011. All the patients were divided into two groups: no combination with fracture of processus styloideus ulnae (group A, 56 cases), combination with fracture of processus styloideus ulnae (group B, 20 cases). The patients in group A and B were treated with open reduction and internal fixation; however the fracture of processus styloideus ulnae was not fixed. The indexes such as clinical data, bone grafting, joint movement, Gartland & Werley score and radiographic score were compared between two groups.

RESULTSThe ulnaris pain of patients in group B was more obvious than that in group A. The local VAS, palmar and dorsal flexion degree of wrist joint, motion VAS, patients satisfaction score, radial and ulnar deviation degree, pronation and supination of forearm degree, Gartland & Werley score and radiographic score were separately 0.1 ± 0.1, (51.1 ± 1.9)°, (60.2 ± 1.9)°, 0.6 ± 0.1 (23.1 ± 0.9)°, (28.7 ± 1.3)° (81.5 ± 2.6)°, (68.2 ± 2.7)° 1.9 ± 0.3, 89.6 ± 12.3 in group A; and separately 0.3 ± 0.3, (51.4 ± 2.3)°, (66.6 ± 1.7)°, 0.5 ± 0.2, (24.5 ± 2.0)°, (26.9 ± 1.8)°, (80.3 ± 2.5)°, (70.3 ± 3.7)°, 1.2 ± 0.4, 92.5 ± 7.5 in group B; there were no statistical differences in above indexes between two groups.

CONCLUSIONWhether the distal radial fracture with a concomitant unrepaired ulnar styloid fracture or not exerts no influence on mainly outcomes including function, radiography and motion of the wrist.

Objective To explore the relationship between 1,25-dihydroxyvitamin D3(1,25-VD3)and alveolar fluid clearance(AFC)in mice in vivo,and investigate its effects in the process of lung fluid clearance. Methods KM male mice were treated with active vitamin D analogue parical-citol(daily i.p. injection)for 2 weeks,and then the in vivo AFC of these mice was measured by bovine serum albumin protein assays. western blot was applied to determine epithelial sodium channel protein levels in lungs of these mice. Results In vivo total AFC was 31.9%±3.8%in vitamin D-treated mice,and significantly lower in the vehicle-treated controls(19.7%±1.9%,P<0.05). Amiloride-sensitive AFC was increased approximate-ly 50%by vitamin D. western blot showed that the expression ofα-epithelial sodium channel was significantly elevated in paricalcitol-treated mouse lungs. Conclusion These observations suggest that vitamin D augments AFC in mice,which may be related to the augment of epithelial sodium channel protein expression. The clinical application of vitamin D therapy may ameliorate pulmonary edema of patients.

Methods: A total of 42 Chang-Bai piglets were divided into 7 groups: control group, 1, 2, 4, 8, 12, and 24 hours wound group. The model of intestinal perforations due to abdominal firearm wound was established in wound groups. Hepatic NF-?B activity was measured with immunohistochemical staining and image analysis in all groups. Hepatocyte apoptosis indexes and serum ALT levels were also determined. Results: Levels of hepatic NF-?B activity in wounded groups were significantly elevated compared with control group, and there were two peaks (1 and 8 hours group P

Two short interfering RNAs (siRNA-RdRp1286, siRNA-RdRp1441) and one short interfering RNA (siRNA-OCP117), targeted to the RNA dependent RNA polymerase (RdRp) gene and outer capsid protein (OCP) gene of Grass carp reovirus (GCRV) respectively, were chemically synthesized and transfected into the CIK cells by lipofectamine 2000. 6 hours after transfection, the transfected CIK cells were challenged with GCRV. The culture media were collected at 48h post challenge and the virus was titrated in microculture system to evaluate the inhibition effect on GCRV replication mediated by siRNAs. Referring to the mRNA level of housekeeping gene beta-actin, RT-PCR was applied to detect the level of GCRV mRNA in transfected and challenged CIK cells. The results showed that the viral titer (lgTCID50/0. 1mL) in siRNA-RdRp1286, siRNA-RdRp1441 and siRNA-OCP117 transfected CIK cells were 4.41 +/- 0.16, 3.83 +/- 0.44 and 1.94 +/- 0.42 respectively, which were significantly lower than that in virus infection positive control (7.92 +/- 0.52) (P < 0.01). No significant change in viral titer was observed in the group transfected with siRNA negative control after challenged with GCRV (7.50 +/- 0.17, P > 0.05). Compared with the mRNA transcriptional level of beta-actin gene in virus infection positive control, the mRNA levels of GCRV in siRNA-RdRpl 286, siRNA-RdRp1 441 and siRNA-OCP117 transfected CIK cells were reduced significantly and the inhibition rate reached to (82.08 +/- 2.15)%, (89.19 +/- 1.14).% and (92.62 +/- 0.17)%, respectively. The mRNA level of GCRV in the siRNA negative control group had no noticeable change (P > 0 05).

OBJECTIVETo investigate the distribution of constitution types of Chinese medicine (CM) in the elderly living at home in Beijing downtown, and to explore its relationship with life habits.

METHODSA total of 3894 senile more than 60 years old were enrolled in this study. Their constitution types of CM were typed using CM constitution questionnaire. Meanwhile, their demographic features, disease condition, diet habits, exercise habits, sleep habits, and so on were investigated. Multivariate Logistic regression analysis was used to evaluate the relationship between life habits and constitution types of CM.

RESULTSThe number of mild type constitution senile was 1111 (28.53%) and the number of biased constitutions 2783 (71.47%). Biased constitutions of the top three were qi deficiency constitution (662, 17.00%), yang deficiency constitution (445, 11.43%), and blood stasis constitution (363, 9.32%). Univariate analysis showed that different habits of diet, exercise, and sleep exist among the senile of different constitutions (P < 0.05). By taking mild type constitution, multivariate Logistic regression analysis (except demographic indices and chronic history) showed that significantly positive correlation existed between qi deficiency constitution and favor for hot food (OR = 1.349, P = 0.015), yang deficiency constitution and favor for hot food (OR = 2.448, P < 0.01), phlegm-wetness constitution and favor for barbecue food (OR = 2.144, P = 0.003), wet-heat constitution and favor for sweet food (OR = 1.355, P = 0.032), wet-heat constitution and favor for tea (OR = 1.359, P = 0.047), blood stasis constitution and favor for hot food (OR = 1.422, P = 0.017), and qi depression constitution and favor for hot food (OR = 1.446, P = 0.031). Regular exercise had negative correlation with qi deficiency constitution (OR = 0.397, P < 0.01), yang deficiency constitution (OR = 0.522, P < 0.01) , phlegm-wetness constitution (OR = 0.475, P < 0.01), wet-heat constitution (OR = 0.647, P = 0.015), blood stasis constitution (OR = 0.608, P = 0.001), qi depression constitution (OR = 0.541, P = 0.001), and special diathesis constitution (OR = 0.466, P < 0.01). Early sleep and rise habit had negative with phlegm-wetness constitution (OR = 0.414, P < 0.01), wet-heat constitution (OR = 0.536, P = 0.015), blood stasis constitution (OR = 0.515, P = 0.004), and special diathesis constitution (OR = 0.526, P = 0.039).

CONCLUSIONSDifferent constitution types of CM might be highly related to specific life habits. Cultivating better life habits can improve biased constitutions of CM.
