AIM: To observe the effect of mineral trioxide aggregate (MTA) combined with fibronectin as pulp capping agents. METHODS: The 48 pulps of 4 cats were exposed mechanically and then capped directly with MTA, MTA combined with fibronectin, calcium hydroxide, fibronectin and starch as control. After 12 weeks observation, the experimental teeth were extracted and observed with scanning electronic microscope. RESULTS: In calcium hydroxide group and MTA group, specimens showed irregular dentin bridge structures along the pulp-MTA interface. In MTA combined with fibronectin group, continuous and complete dentin bridge structures were found along the pulp-MTA interface, the crystalline-like structures were in direct contact with the dentin wall of pulp chamber, the exposed pulp sites were closed by the dentin bridge. In fibronectin and starch group, no reparative dentin was observed. CONCLUSION: The present experiment indicated that MTA combined with fibronectin was an effective pulp-capping material and may have potential for clinical application. [

Objective To observe the effect of team-based continuous nursing on improving the life function of children with cerebral palsy. Methods From March 2014 to March 2016, 35 children aged 18-36 months with cerebral palsy were selected as the experimental group;35 matched patients with the same age, same gender, same Gross Motor Function Classification System (GMFCS) and functionally similar were selected as the control group by matching design. Among them, 32 cases were followed up in the experimental group while 30 cases in the control group. In the control group, routine discharge education was adopted, but the experimental group was treated by team-based continuous nursing. The ability of daily living was evaluated by the Pediatric Evaluation of Disability Inventory (PEDI). Neuropsychological development was evaluated by the Gesell Development Scale and Body balance was evaluated by the Berg Balance Function Scale after discharge and also after 6 months follow-up. Results After the intervention for 6 months, the functional skill and assisting assistance of PEDI was (77.56 ± 23.58), (38.78 ± 13.96) points in the experimental group, and (65.12 ± 24.23), (30.35 ± 12.78) points in the control groups, there were significant differences between two groups(t=2.0485, 2.4750, P<0.05). The scores of Gesell Development Scale was (76.12 ± 18.35) points in the experimental group, and (71.85 ± 18.46) points in the control group, there were no significant differences between two groups(P>0.05) , but the experimental group was higher than the control group. The scores of Berg Balance Function Scale was(33.20 ± 4.12) points in the experimental group, and (29.67 ± 4.98) points in the control group, there were significant differences between two groups (t = 3.0488, P<0.05). Conclusions To improve the life function of children with cerebral palsy, the implementation of the team-based continuous nursing had a significant effect.

Objective:To observe the clinical effect of acupuncture therapy to support yang and consolidate the constitution for cervical spondylosis of vertebral artery type (CSA). Methods:A total of 72 patients with CSA were randomly divided upon the random digital table into an acupuncture- moxibustion group and an acupuncture group, 36 cases in each group. The acupuncture-moxibustion group was treated by electroacupuncture (EA) at bilateral Fengchi (GB 20) and C4-6 Jiaji (EX-B 2), in combination of moxibustion at Baihui (GV 20), Shenshu (BL 23) and Mingmen (GV 4) to support yang and consolidate constitution. The acupuncture group was given by routine EA at bilateral Fengchi (GB 20), cervical Jiaji (EX-B 2), Tianzhu (BL 10), Jianjing (GB 21), Houxi (SI 3), Hegu (LI 4) and Waiguan (TE 5). The treatment was given once every day and continuous six sessions made one course. After 2-course treatment, the improved situation of clinical symptoms and clinical effect were observed in the two groups. Results:The total effective rate was 91.7% in the acupuncture-moxibustion group and 61.1% in the acupuncture group. The difference of the total effective rate between the two groups was statistically significant (P<0.05). After treatment, the scores of the clinical symptoms in the two groups were obviously decreased than those of the same group before treatment (P<0.01). The differences in the scores between the two groups were statistically significant (P<0.05). Conclusion:Acupuncture-moxibustion treatment to support yang and consolidate constitution is better than the routine acupuncture therapy in the therapeutic effect for CSA.

Objective To observe the effect ofDanhuai-Yinxie condensed pill on the expression of VEGF and its receptors in the model rabbits with psoriasis.Methods Fourty-two healthy Japanese white rabbits were randomly divided into the control group, the model group, the Acitretin group, and the low-, medium- and high-doses ofDanhuai-Yinxie condensed pill groups. The backs of rabbits’ ears were wiped with 5% propranolol for 4 weeks in the latter four groups, while with saline for the same period in the control group. The rabbits in the Acitretin group were intragastric administrated with 1% Acitretin one day since the models of psoriasis were successed, while the rabbits in the low-, medium- and high-doses ofDanhuai-Yinxie condensed pill groups were intragastric administrated withDanhuai-Yinxie suspension 20, 40, 80 mg/kg daily, respectively. The rabbits in the control and model groups were intragastric administrated with equal-volume saline daily.

BACKGROUND:18-Alkylated-chitosan has been proved to exhibit a good coagulation capacity through hydrophobic modification. OBJECTIVE:To improve the adhesion between the material and the wound through the introduction of alkylated-chitosan molecules. METHODS:The alkyl group was introduced in the chitosan by potentiodynamic method to prepare the alkylated-chitosan with different substitution degrees (7%,16%, 26%and 40%), and then their structure, viscosity, porosity, water absorption, contact angle and in vitro coagulation capacity were detected. Thirty New Zealand rabbits were enrol ed, modeled into the left femoral artery hemorrhage, and randomized into six groups, including four experimental groups, positive control and control groups, fol owed by treated with alkylated-chitosan sponges with different degrees of substitution, absorbable hemostatic gauze and chitosan sponge, respectively. Afterwards, the blood loss and clotting time were observed. RESULTS AND CONCLUISON:With the degree of substitution increased, the viscosity of alkylated-chitosan increased firstly and then decreased, the porosity and water absorption decreased gradual y, and the contact angle on a rise. Compared with chitosan, different alkylated-chitosans showed a better henostatic effect in vitro, especial y the alkylated-chitosan with 16%substitution degree. The blood loss and clotting time in the experimental groups except that the alkylated-chitosan with 7%substitution degree were significantly lower than those in the control group (P<0.05);the bold loss in the alkylated-chitosan with 40%substitution degree group was significantly lower than that in the positive control group (P<0.05). These findings suggest that the alkylated-chitosan with 40%substitution degree exhibits the best hemostatic effect in vivo.

AIM: This study was aimed to assess the effect of mineral trioxide aggregate (MTA) combined with fibronectin on reparative dentinogenesis and odontoblast differentiation, investigate the possible mechanism underlying traumatized pulp repair, which would facilitate the choosing of ideal pulp capping agents. METHODS: 192 teeth from 16 adult cats were used. Class V cavties were prepared on the facial surface. The pulps of cats were exposed mechanically and then capped directly with MTA, MTA combined with fibronectin, calcium hydroxide, fibronectin and starch as control. The pulpal tissue reactions were assessed by light microscopy at healing interval of 1 and 4 weeks.RESULTS: 1 week after pulp capping, no reparative dentin formation was observed in each group. 4 weeks after pulp capping, the dental pulps capped with MTA/fibronectin showed no or slight cellular inflammatory responses and odontoblast differentiation with tublar dentin bridge on the exposed sites. In MTA group, the dental pulps showed slight to moderate cellular inflammatory responses with osteodentin formation. In calcium hydroxide group, the pulps showed moderate to severe inflammatory responses with calcified matrix. In fibronectin and starch group, no dentin bridge formation was observed, the pulps showed severe cellular inflammatory responses.CONCLUSION: (1) MTA combined with fibronectin induced to form complete and tublar dentin bridge. In MTA group, most of the formed dentin bridge was irregular and osteodentin. (2) MTA combined with fibronectin is a bioactive pulp-capping agent and has a great worth in vital pulp therapy.
