Objective To investigate the clinical effect of treatment with local skin flap after primary surgical resection of non melanoma skin cancer.Methods A total of 176 patients with head and facial skin cancer who were admitted into our hospital from September 2008 to September 2015 were divided into three groups according to different repair plans.Namely,the suture group (41 cases),the local skin flap group (81 cases) and the skin graft group (54 cases).The repair effect of the three groups were compared after the operation.Results The good rate was 68.39%(28/41) in the suture group,98.77%(80/81) in the local skin flap group,and 83.33%(45/54) in the skin graft group,and it was significantly higher than any of the other two groups with statistically significant difference(P<0.05).The satisfaction rate of the local skin flap group was significantly better than that of the suture group,and the difference was statistically significant(P<0.05).But there was no significant difference in the satisfaction rate when compared with the skin graft group(P>0.05).The 3 groups were followed up for a period of 1 year,as a result,there was no recurrence and distant metastasis.Conclusion For patients with head and facial non melanoma skin cancer,repaired with local skin flap healing treatment after primary surgical resection can not only get high healing rate but also significant improvement of patient satisfaction rate.In addition,it can lower the rate of recurrence and distant metastasis after operation.

OBJECTIVETo explore the effect of Jingui Shenqi pill (JGSQP) with various concentrations at different time points on pituitary adrencorticotropic hormone (ACTH) gene expression level in Shen-Yang deficiency rats.

METHODSThe Shen-Yang deficiency rats were randomly divided into the model control group and the high, medium and low dosage of JGSQP groups. Reverse transcriptase polymerase chain reaction was used to observe the effect of JGSQP on the ACTH mRNA of pituitary tissue in rats treated at different time points (10 d, 20 d, 30 d).

RESULTSAs compared with that in the model group, the ACTH gene expression level was significantly higher in the high dose JGSQP group (P < 0.05), and the increment in the medium dosage group was significantly higher in comparing with that in the high and low dosage groups (P < 0.05 or P < 0.01).

CONCLUSIONThrough up-regulation on ACTH gene expression is possibly one of the mechanisms of JGSQP in treating Shen-Yang deficiency.

Objective To observe the effects of an enriched environment (EE) on cognitive functioning and the synaptic plasticity of mice modeling post-stroke cognitive impairment (PSCI) and explore the possible mechanisms involved.Methods Mice modeling PSCI and sham-operated mice were randomly divided into 3 groups:sham-operated mice in a standard environment (the Sham+SE group),PSCI mice in a standard environment (the PSCI+SE group) and PSCI mice in an enriched environment (the PSCI+EE group).The cognitive functioning of all of the mice was quantified using a Morris water maze and their hippocampal long-term potentiation (LTP) was recorded using an electrophysiological method.The level of synaptophysin was detected using Western blotting.Synaptic ultrastructure in the hippocampus was imaged using electron microscopy.Results Compared with the Sham +SE group,the PSCI+SE group showed significantly poorer water maze performance and failed induction of contralateral LTP.Their average level of synaptophysin was significantly lower,and significant adverse changes in the synaptic ultrastructure of the hippocampus were observed,including a decreased number of synapses.The average width of the synaptic cleft,postsynaptic density and the interface curvature of the synapses were all less desirable.All of the measurements of the PSCI+EE group improved significantly compared to those of the PSCI+SE group,but were still significantly poorer than those of the Sham+SE group.Conclusions An enhanced environment can improve the cognitive functioning of mice modelling PSCI.It may be that an EE can improve synaptic plasticity in the hippocampus contralateral to the stroke.

To develop a LC-MS/MS method for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials, the column was Agilent ZORBAX Eclipse plus C18 (3.0 mm x 50 mm, 1.8 µm), and the mobile phase consisted of methanol-water (containing 0.2% formic acid) (95:5) at a flow rate of 0.5 mL · min(-1). The multiple reaction ion monitoring (MRM) with an ESI interface in the negative ion mode was selected. The results showed that the linear ranges of five kinds of ginkgolic acids were in the range of 0.2-36.0 µg · L(-1) (r ≥ 0.999 5). The lowest limit of quantification (LOQ) of ginkgo acid C13: 0, C15:1, C17:2, C15:0 and C17:1 were 0.18, 0.18, 0.21, 0.10 and 0.20 µg · L(-1), respectively. The average recovery was between 73.28% and 87.56%, and the average content of total ginkgolic acids in three batches of samples was in the range of 0.023-0.028 µg · g(-1), which was much lower than 2 µg · g(-1) prescribed in drug registration standards. This method is simple and rapid with high sensitivity, which can be used for the determination of five kinds of trace ginkgolic acids in diterpene ginkgolides meglumine injection materials.

BACKGROUND: Long-term use of flexible denture prosthesis will increase the incidence of caries and periodontal disease, and partial denture stomatitis. The addition of fluoride in the prosthesis material can prevent and reduce the incidence of these diseases. Currently, increasing research addresses the addition of fluoride into dental materials at home and abroad, but little is reported on the addition of sodium monofluorophosphate (Na2(PO3)F into flexible denture materials and on the relevant mechanical performance.OBJECTIVE: To evaluate the mechanical properties of flexible denture materials containing different fluoride concentrations.METHODS: Totally 180 elastic denture samples were made at the three different sizes of 80 mm×51 mm×1 mm (n=60), 20 mm×5 mm×5 mm (n=60), 25 mm×2 mm×2 mm (n=60). Then, elastic denture samples containing Na2(PO3)F 0 (control), 3%, 5%, 10%, 15%, 20% were prepared in each size groups. The tensile strength, flexural strength and Shore A hardness of the samples were tested.RESULTS AND CONCLUSION: When the mass ratio of fluoride was up to 10%, the tensile strength and flexural strength reduced a little (P > 0.05). When the mass ratio of fluoride was up to 15%, the tensile strength and flexural strength were significantly lower than those of non-fluoride samples (P < 0.05). When the mass ratio of fluoride was up to 20%, the tensile strength, flexural strength and Shore A hardness were significantly lower than those of non-fluoride samples (P < 0.05). To conclude, Na2(PO3)F content has a significant effect on the tensile strength, flexural strength and Shore A hardness, and 10% is the best proportion of Na2(PO3)F. The mechanical properties of fluoride-containing flexible denture materials will be changed if the mass ratio of fluoride is higher than 10%.
