Objective To investigate the effects of playful training on home environment and development in children with cerebral palsy. Methods89 children with cerebral palsy were divided into observation group (45 cases) and control group (44 cases). All children were treated with normal strengthen rehabilitation in hospital. The observation group received the training playfully. They were assessed with the Home Observation for Measurement of the Environment (HOME) and Bayley Scale of Infant Development (BSID) before and 6 months after treatment. ResultsAfter treatment, The HOME scores in observation group was significantly better than those before treatment and in control group （P<0.01）. The Psychomotor Dvelpment Index (PDI) of BISD was improved in both groups （P<0.01） with significant different between them（P<0.05）. The Mental Development Index (MDI) of BISD in observation group was significantly better than those before training and in control group （P<0.01）. ConclusionPlayful training can improve the development and home environment in children with cerebral palsy.

Objective To investigate the effect of apoptosis-related gene p53 on the apoptosis of retinal capillary cells in rats with spontaneously hypertensive (SHR) after ischemic reperfusion injury. Methods A total of 60 SHR rats were randomly divided into sham group (SHR-SH) and retinal ischemie reperfusion group (SHR-RIR), which were subdivided into 5 subgroups according to the time after RIR: 2, 6, 24, and 72 hours and 7 days, with 6 rats in each subgroup. Another 60 Wistar-Kyoto (WKY) rats were divided into the same groups as the SHR rats as the control. The RIR model was set up. The apoptosis of retinal capillary cells was detected by terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) methods and the expression of p53 was determined by streptavidin-perosidase (SP) immunohistochemistry. Results The apoptosis rate of retinal capillary cells in the 5 SHR-RIR groups was (8.64±0.56)%, (14.92±0.99)%, (24.72±2.98)%, (16.53±1.80)%, and (7.12±1.10)%,respectively. The expression of p53 in SHR-RIR groups increased at the 2nd hour after RIR, reached the peak at the 24th hour, kept the high level at the 72nd hour, and remained a little at the 7th day, which was significantly different from which in the SHR-SH groups (P<0. 01). The expression of p53 were higher in SHR-IR groups than that in the WKY-RIR groups (P<0. 01). Conclusions p53 may play a part in RIR injury by inducing or promoting apoptosis. The apoptosis of retinal capillary cells after RIR is more severe under the hypertension, and reaches the peak at the 24 hour after RIR.

The aim of this study was to establish an assessment method for determining α-Gal (α-1, 3-galactosyle) epitopes contained in animal tissue or animal tissue-derived biological materials with ELISA inhibition assay. Firstly, a 96 well plate was coated with Gal α-1, 3-Gal/bovine serum albumin (BSA) as a solid phase antigen and meanwhile, the anti-α-Gal M86 was used to react with α-Gal antigens which contained in the test materials. Then, the residual antibodies (M86) in the supernatant of M86-Gal reaction mixture were measured using ELISA inhibition assay by the α-Gal coating plate. The inhibition curve of the ELISA inhibition assay, the R2 = 0.999, was well established. Checking using both α-Gal positive materials (rat liver tissues) and α-Gal negative materials (human placenta tissues) showed a good sensitivity and specificity. Based on the presently established method, the α-Gal expression profile of rat tissues, decellular animal tissue-derived biological materials and porcine dermal before and after decellular treatment were determined. The M86 ELISA inhibition assay method, which can quantitatively determine the α-Gal antigens contained in animal tissues or animal tissue-derived biomaterials, was refined. This M86 specific antibody based-ELISA inhibition assay established in the present study has good sensitivity and specificity, and could be a useful method for determining remnant α-1, 3Gal antigens in animal tissue-derived biomaterials.

Objective: To compare the efficacy of postoperative adjuvant radiotherapy and non-radiotherapy in patients with extrahepatic cholangiocarcinoma and gallbladder carcinoma by a meta-analysis. Methods: The controlled clinical trials of postoperative adjuvant radiotherapy versus non-radiotherapy of extrahepatic cholangiocarcinoma and gallbladder carcinoma were searched from PubMed, EMbase, Cochrane Library, Wanfang database, CNKI, Chongqing VIP and CBM databases. The obtained data were analyzed using RevMan 5.3 and Stata 14.0 statistical software. The difference between two groups was estimated by calculating the odds ratio (OR) with 95% confidence interval (CI). Results: A total of 20 controlled clinical trials involving 1258 extrahepatic cholangiocarcinoma and gallbladder carcinoma patients were included in this meta-analysis. The meta-analysis demonstrated that the 5-year survival rate in the adjuvant radiotherapy group was significantly higher than that in the non-radiotherapy group (OR=1.67, 95%CI: 1.29-2.18, P=0.001). The 5-year survival rates in those with lymph node positive disease (OR=7.44, 95%CI: 1.24-44.72, P=0.03) and positive margins disease (OR=3.43, 95%CI: 1.56-7.75, P=0.002) were significantly enhanced by postoperative adjuvant radiotherapy. The local recurrence rate in the adjuvant radiotherapy group was significantly lower than that in the non-radiotherapy group (OR=0.56, 95%CI: 0.39-0.80, P=0.01), whereas the distant metastasis rate did not significantly differ between two groups (OR=1.22, 95%CI: 0.86-1.73, P=0.27). The incidence rates of acute toxicity and chronic toxicity of grade ≥3 caused by radiotherapy were 0-11.9% and 0-21.7%, respectively. Conclusion Compared with non-radiotherapy, postoperative adjuvant radiotherapy is a safer and more effective postoperative treatment for extrahepatic cholangiocarcinoma and gallbladder carcinoma.

Excessive levels of cadmium (Cd) in soil exert serious negative impacts on soil ecosystems. Microorganisms are a common component of soil and show great potential for mitigating soil Cd. This review summarizes the application and remediation mechanisms of microorganisms, microbial-plants, and microbial-biochar in Cd-contaminated soil. Microorganisms such as Bacillus, Acinetobacter, Pseudomonas, and arbuscular mycorrhizal fungi (AMF) can change the biological validity of Cd through adsorption, mineralization, precipitation and dissolution. Different factors such as pH, temperature, biomass, concentration, and duration have significant effects on Cd bioavailability by microorganisms. Pseudomonas, Burkholderia, and Flavobacterium can promote the uptake of Cd²⁺ by hyperaccumulator through promotion and activation. Biochar, a soil amendment, possesses unique physicochemical properties and could act as a shelter for microorganisms in agriculture. The use of combined microbial-biochar can further stabilize Cd compared to using biochar alone.
