ObjectiveTo investigate the children with cerebral palsy (CP) in rehabilitation, their families and need of society support. Methods150 children with CP in rehabilitation participated in this study. A questionnaire was designed to investigate their basic situation, family status, society concern and requirements for society support, which completed by their parents. Results150 questionnaires were completed efficiently. 75 children were firstly treated before 1 year old. The rehabilitation treatments were effective to 130 children. 126 children appeared some disorder in emotion and personality. Home education was the main rehabilitation way in 133 children. The educational background of 59.4% mothers were senior high school or below. The income was less than 60 thousand yuan in 76.7% families, but spent more than 40 thousand yuan per year on treatment in 54.7% families. One or both parents in 119 families were forced to stop working. 93.3% of them suffered emotion pressure and 56.7% lacked the knowledge about CP. 81% families thought that more social support should be offered in 6 aspects including government welfare, social security, medical institutions, psychotherapy, community services and legal aid. ConclusionAll society should pay more attention on the children with CP and provide a good rehabilitation environment for them.

Objective To investigate the molecular mechanism of bone marrow mesenchymal stem cells (BM-MSCs) in repairing cisplatin-induced acute renal injury.Methods The rats were injected 6 mg/kg of cisplatin intraperitoneally,and bone marrow mesenchymal stem cells (BM-MSCs group) or PBS (PBS group) were injected respectively via tail vein after 24 hours.The rats without injecting cisplatin were selected as a normal control group.The repair effect of BM-MSCs on renal injury was observed by HE staining and immunohistochemistry.In addition,NRK-52E cells were cultured in vitro and treated with cisplatin for 6 hours.Then,NRK-52E cells were continued to culture for 48 hours or co-cultured with BM-MSCs for 48 hours,and NRK-52E cells untreated with cisplatin were used as a control.The expression levels of miR-92b and its target gene PTEN were detected by qRT-PCR,and the expression level of p-Akt by western blot.Results HE staining showed that the tubular protein casts in BM-MSCs group were significantly less than that in PBS group,and that the renal tubular structure was significantly improved in BM-MSCs group.Immunohistochemical staining indicated that the number of cells expressing proliferating cell nuclear antigen (PCNA) in BM-MSCs group (131.0 ± 14.4) was significantly higher than that in PBS group (42.2 ±6.1,t =11.28,P ＜0.01).qRT-PCR results showed that in the vivo experiment,compared with the expression level of miR-92b and PTEN in the normal control group (1.11 ± 0.78,1.01 ± 0.21),PBS group were (4.64 ± 1.06) and (0.61 ± 0.2),respectively (all P ＜ 0.05);BM-MSCs group were (2.27 ± 0.81) and (1.1 ± 0.1),respectively (all P ＜ 0.05).In vitro experiment,compared with the expression level of miR-92b and PTEN in the negative control group (1.12 ± 0.77,1.02 ± 0.13),cisplatin group were (7.64 ± 0.72) and (0.58 ± 0.2),respectively (all P ＜ 0.05),cell group were (4.38 ± 0.50) and (1.15 ± 0.23),respectively (all P ＜ 0.05).Western blot results showed that compared with the expression level of p-Akt in cisplatin group (0.96 ± 0.18),p-Akt expression in cell group was (2.11 ± 0.11,P ＜ 0.01).Conclusion BM-MSCs may repair the cisplatin-induced acute renal injury via down-regulating the expression level of miR-92b.

0.05). Conclusion When TOFR recovers to 0.55,antagonism of residual neuromuscular blockade is still necessary.Different doses of neostigmine may antagonize vecuronium-induced residual neuromuscular blockade,and lower dose of neostigmine(10-20 ?g/kg) is recommended.

Objective To investigate the clinical effect of systemic rehabilitation on stiffness of finger joints after hand injury. Methods A total of 213 stiff fingers were observed in patients with hand injury. All the patients were administered with therapeutic exercise, physical modalities and splinting. The improvement of the patients in terms of active range of motion (AROM) and passive range of motion (PROM) of their fingers was graded as excellent, good, adequate or poor according to the standard the authors set. Results With regard to their AROM and PROM, 82.2% and 94.8% of the patients got excellent improvement, 97.7% and 100% of the patients got excellent to adequate improvement, respectively. The finger function was increased from 17% to 56%. Conclusion Systemic rehabilitation can increase the AROM and PROM of stiff finger effectively and improve the patients' hand function.

Objective To observe the value of contrast-enhanced ultrasonography (CEUS) in quantitatively evaluating the evolution of the blood supply of rabbit liver VX2 tumor models in early stage. Methods Eighteen liver VX2 tumor models of rabbits were divided into 3 groups randomly (each n=6). CEUS was performed on the 10th, 15th and 20th day group after establishemnt, resepectively. Time intensity curve (TIC) was plotted, the rabbits' liver tumor and surrounding normal liver tissue were resected for immuno-histochemistry and microvessel density (MVD) count. Results CEUS showed that the rabbit liver VX2 tumor present a typical malignant tumor imaging fast-in and fast-out in early stage. TIC showed that the time to peak (TTP) of hepatic tumor is shorter than that of surrounding normal liver tissue in all three groups (P＜0.01), no statistical difference of tumor's TTP was detected among three groups (P>0.05). Absolute enhanced intensity (AEI) and MVD reduced in turn of 10th, 15th and 20th day group. MVD of tumor was higher in 10thday group than surrounding normal liver tissue (P＜0.01), while was equal in 15th day group (P>0.05) and lower in 20th day group (P＜0.01). AEI of liver tumor had positive correlation with MVD (r=0.83, P＜0.05). Conclusion AEI of TIC can be used to quantitatively assess the evolution of the blood supply in rabbit liver VX2 tumor models. The blood supply in early stage of rabbit liver VX2 tumor models shows a gradual descent process from abundant blood supply to medium blood supply and then low blood supply.
