Objective To observe the effectiveness of comprehensive rehabilitation on the recovery of motor function of patients with severe cerebral injury in recovery phase.Methods 72 cases with severe cerebral injury in recovery phase were randomly divided into rehabilitation group (n=38) and control group (n=34). Patients in control group were treated with routine method, and those in rehabilitation group with comprehensive rehabilitation treatment in addition.Results Motor function, activities of daily living (ADL) and complication of patients were evaluated at the first day and two months later after be in hospital. The effect of comprehensive rehabilitation treatment were better than that of control group(P<0.05,P<0.01). Conclusion Comprehensive rehabilitation is important to the patients with severe cerebral injury of recovering, not only in recovery of motor function but also in reducing the complication.

Polydatin is a monocrystaline compound isolated from Polygonum cuspidatum Sieb. et Zucc. (Polygonaceae) with biological properties, such as anti-inflammation, anti-oxidative and nephroprotective effects. Increasing number of studies have demonstrated the protective effect of polydatin on renal ischemia reperfusion injury. However, the possible mechanisms of this protection are not fully elucidated. This study aimed to investigate the effect of polydatin on ischemia-reperfusion induced expression of toll-like receptor4 (TLR4) in rat renal tubular epithelia cells (NRK-52E), and analyze the mechanism of polydatin on TLR4 signal pathway. The cultured NRK-52E cells were incubated in three gas incubators for a period of 6 h at hypoxia and 24h at reoxygenation to simulate the ischemia-reperfusion injury in vitro. TLR4 mRNA level was analyzed by real-time-PCR, and the protein expression of TLR4 and NF-κB by Western blotting, while TNF-α and IL-1β proteins expressions were detected by ELISA. Polydatin downregulated I/R induced mRNA and protein expressions of TLR4, and decreased the protein expression of NF-κB, TNF-α and IL-1β. The TLR4 blocker partially antagonized the effect of I/R on NF-κB signaling, and such inhibitory effect was markedly enhanced by polydatin. In the present study, polydatin protects NRK-52E cells from I/R injury possibly by relieving the inflammatory response through regulation of TLR4/NF-κB signaling pathway.

ObjectiveTo investigate the prevalence and distribution characteristics of dental fluorosis of children aged 8 - 12 in Wushan and Fengjie counties of Chongqing and to provide a scientific basis for prevention and control of the disease.MethodsTwenty townships(towns) in Fengjie county and 18 in Wushan county were selected as survey points by random cluster sampling in 2010.Dental fluorosis of all the children aged 8 - 12 was examined with Dean index.The detection rate of children's dental fluorosis,defect rate and dental fluorosis index were compared between the two counties.Results Totally 38 209 children aged 8 - 12 were investigated.The total detection rate of dental fluorosis was 43.09％( 16 466/38 209) in the two counties.The detection rates of dental fluorosis in Wushan and Fengjie were 48.98％ (9397/19 186)and 37.16％(7069/19 023),respectively,and the difference was statistically significant(x2 =544.03,P ＜ 0.01 ).Total detection rates of dental fluorosis of the five age groups(8,9,10,11,and 12-year-old age groups) were 32.52％(2157/6632),40.07％(2672/6668),43.67％(3420/7831 ),46.01％ (3861/8391) and 50.14％ (4356/8687),respectively,and the difference was statistically significant (x2 =510.50,P ＜ 0.01),Dental fluorosis indexes in Wushan and Fengjie were 0.713 and 0.485,respectively.Defect rates of dental fluorosis in Wushan and Fengjie were 4.05％ (777/19 186) and 1.57％(298/19 023),respectively.Conclusions The total detection rate of dental fluorosis of the two counties is still high,which gradually increases with age.Wushan is still an endemic area of dental fluorosis,and Fengjie is at the edge of the

Objective To analyze the fetus chromosome abnormalities in women with advanced maternal age under the universal two-child policy. Methods A total of 10607 women underwent prenatal diagnosis proce-dures from the year of 2015 to 2016,among which 3569 cases were with advanced maternal age. Cytogenetic karyotyping was conducted with chromosomal microarray analysis(CMA)in 854 cases. The ration of chromosome abnormalities in the two population groups(aged from 35~39 and over 40)were counted. The type of abnormali-ties were also analyzed. Results The ration of women with advanced maternal age in 10607 cases underwent pre-natal diagnosis between 2015 and 2016 was 33.6%. The respective rations were 27.2%and 37.9%. The detection rates of chromosome abnormalities were 7.9% and 10.8%,with significantly difference. The significant differences were also found in the detection rate of chromosome aneuploidies ,but no differences in other chromosome abnor- malities. CMA was benefit to detect the micro chromosome abnormalities. Conclusions In 2016,the number of prenatal diagnosis procedures increased under the two-child policy. The detection rate of chromosome abnormalities also significantly increased. The incidence of chromosome abnormalities was higher with the growing age of preg-nant women. Genetic counseling must be presented and prenatal diagnosis should be promoted in women with ad-vanced age.

Objective To explore the clinical significance of the blood lactic dehydrogenase(LDH), ?_2-microglobulin(?_2-MG),D-dimer measuring in the diagnosis and treatment of Non-Hodgkin lymphoma. Methods In 40 cases with NHL,LDH was measured by L-P continuous monitoring method,?_2-MG was measured by luminescent immunoassay,D-dimer was measured by immunoturbidimettic assay.Results The levels of the blood LDH,?_2-MG and D-dimer in patients with NHL were higher than those of in the controls(P 0.05).Con- clusion The levels of blood LDH,?_2-MG,D-dimer can be taken as an auxiliary clinical index to diagnose, classify the phase,evaluate the effectiveness of treatment and prognosis in the NHL patients,and have impor- tant clinical significance.

To evaluate the immunogenicity of inactivated SARS coronavirus (SARS-CoV), three groups of rabbits were immunized three times at 2-week intervals with inactivated vaccine + adjuvant, adjuvant,and normal saline respectively. Eight batchs of serum were sampled from the auricular vein at day 7 to day 51, and specific IgG antibody titers and neutralizing antibody titers were detected by indirect ELISA and micro-cytopathic effect neutralizing test. Antibody specificity was identified by proteinchip assay.Histopathological changes were detected by H&E staining. The results showed that, rabbits in the experimental group immunized with inactivated SARS-CoV all generated specific IgG antibodies with neutralizing activity, which suggested the inactivated SARS-CoV could preserve its antigenicity well and elicit an effective humoral immune responses. The peak titer value of specific IgG antibody and neutralizing antibody reached 1:40960 and 1:2560 respectively. In the experimental group, no obvious histopathological changes was detected in the H&E stained slides of heart, spleen, kidney and testis samples, but the livers had slight histopathological changes, and the lungs presented remarkable histopathological changes. These findings are of importance for SARS-CoV inactivated vaccine development.

OBJECTIVETo study the role of microfilament polymerization in menchanotransduction by human periodontal ligament fibroblast (hPDLFs).

METHODSIn tension-force group, hPDLFs were treated by tension-force values of 18% for 8 h, 16 h, 24 h. In tension-force and inhibitor group, the sample was treated with 5 microg/mL cytochalasin B before using tension-forece. Each sample was collected and the expression of cyclooxygenase-2 was measured by using immunohistoche staining.

RESULTSIn tension-force group, the expression of cyclooxygenase-2 enhanced with the extension of loading time. In tension-force and inhibitor group, cyclooxygenase-2 expression was depressed and had no relation with loading time.

CONCLUSIONTension-force induced cyclooxygenase-2 expression is mediated by microfilament, disruption of the microfilament polymerization will destroy mechanotransduction in hPDLFs.
