Objective To evaluate effects of different types of gingival flap suture on the quality of life in patients after removal of mandibular third molar. Methods A randomized, controlled clinical trial design was adopted. Sixty-two patients in oral surgery department, Stomatology Hospital of Tianjin Medical University were selected. Patients were required removal of bilateral symmetry impacted mandibular third molars, and enclosed suture (primary suture) was used in one side, open drainage suture (secondary suture) was used in the other side. The postoperative symptom severity scale (PoSSe scale) was used to evaluate the quality of life in patients after removal of mandibular third molar. The evaluation was completed 7 days after surgery, and the scale was compared between two groups. Results A total of 57 cases of clinical data were enrolled in the final analysis. The operative time for primary suture group was (17.7±4.6) min, and the operative time for secondary su?ture group was (16.3 ± 5.1) min, the difference was not statistically significant (t=1.539, P>0.05). The PoSSe score was sig?nificantly higher in primary suture group (26.348 ± 12.414) than that of secondary suture group (21.633 ± 11.382, P<0.05). Conclusion Secondary suture reduces the influence of teeth removal on quality of life in patients through relieving pain and swelling, and which is suitable for clinical application.

OBJECTIVE:To study the pharmacokinetic characteristics of Puerarin solid self-microemulsion capsules in rats in vi-vo. METHODS:The rats were randomly divided into two groups with 18 rats in each group. They were given Puerarin solid self-mi-croemulsion capsules(S-SMEDDS capsules)and commercially available Yufeng ningxin tablet,with the dose of 158.15 mg/kg puer-arin. The 0.2 ml blood samples were collected from tail vein 0,5,10,20,40,60,90,120,180,240,360,480,600 min after medication,respectively. The blood concentration of puerarin was determined by HPLC,and pharmacokinetic parameters and rela-tive bioavailability were calculated by using 3p87 software. RESULTS:The metabolism of puerarin was one-compartment model in rats. Pharmacokinetic parameters of S-SMEDDS capsules and Yufeng ningxin tablet were as follows as cmax of (1.032 0 ± 0.020 6) and(0.587 3±0.011 7)μg/ml,t1/2ke of(116.431 4±2.166 0)and(88.222 6±1.752 4)min,AUC0-t of(261.532 2±1.464 0)and (102.835 5±1.957 4)μg·min/ml. Relative bioavailability was 238.77%. CONCLUSIONS:Compared with Yufeng ningxin tablet, S-SMEDDS capsules are absorbed more completely and removed faster.

This study was aimed to observe the effect ofZi-Bu Pi-Yin Recipe (ZBPYR) on the mRNA expressions of NMDA receptor subunits NR1, NR2A, NR2B in different brain regions of spleen-yin deficiency Alzheimer's Disease (AD) model rats. The levels of NR1, NR2A, NR2B mRNA expressions were detected by using RT-PCR method. The results showed that the levels of NR1, NR2A, NR2B mRNA expressions of AD group and spleen-yin deficiency AD group decreased significantly (P < 0.05). The levels of NR1, NR2A, NR2B mRNA expressions of ZBPYR treatment group increased significantly (P < 0.05). It was concluded that the expression levels of NMDAR mRNA in different brain regions of the ZBPYR treatment group increased significantly, which indicated that ZBPYR may up-regulate the protein expressions of NMDAR by increasing the expression levels of NMDAR mRNA, thereby to play the anti-dementia effect.

Objective To prepare a targeted antitumor drug delivery system using large-inner-diameter multi-walled carbon nanotubes (LID-MWCNTs) for sustained release and to study its performance. Methods LID-MWCNTs were puri?fied and oxidized,then use nanocarriers and USTs as homologous blockers. Folic acid and fluorescent labels were conjugat?ed onto the external surfaces of nanocarriers. CDDP (cisplatin) was encapsulated and ultrashort tubes (USTs) were employed to block the drug entry/exit paths. The microstructure of resulted drug delivery system (DDS) was observed, while drug load?ing efficiency and drug release profile in vitro were determined. The tumor-targeting property and cytotoxicity of DDS were also assessed. Results LID-MWCNT based sustained release targeted drug delivery system was established. Drug loading efficiency of CDDP@UST-FA-LID-MWCNTs was as high as 70.97%. A typical biphasic sustained release pattern was dem?onstrated, and the accumulating release time was 18 h. DDS exhibited a certain kind of tumor-targeting property, and inhibit?ed proliferation of tumor cells in a dose-dependent manner. Conclusion CDDP@UST-FA-LID-MWCNT drug delivery system exhibited an improved drug loading efficiency and a sustained drug release profile. It could specifically target the tu?mor cells and had a significant antitumor effect.

Objective To analyze the effects of acute depletion of liver-specific insulin signaling on secretion of apolipoprotein B (apoB) and triglyceride (TG).Methods Based on Cre-LoxP principle,a promoter of hepatic tissue specific albumin gene was inserted into upstream of the cre recombinase gene.Albumin-Cre adenovirus (Ad-CRE) and GFP adenovirus (Ad-GFP) were amplified in 293A cells and purified before intravenous administration to mice.After adenovirus infection for 2 days,4 days and 6 days,blood samples from mice were collected and hepatic tissues were frozen.The secretion rates of hepatic newly synthesized apoB and very low density lipoprotein (VLDL)-TG were determined by injection of Triton WR-1339.The levels of plasma cholesterol (TC) and TG were measured.The expressions of insulin receptor and other lipoprotein metabolism related proteins in hepatic tissues were analyzed by Western blot.Results After 2 d,4 d and 6 d of the Ad-CRE injection into mice,insulin receptor expression was reduced by 30.50% (P<0.05),60.12% (P< 0.01) and 99.54% (P<0.001),and VLDL-TG secretion rate was decreased by 20.43% (P<0.05),33.63% (P<0.05) and 44.21% (P<0.01),respectively.Expressions of sterol regulatory binding proteins 1,fatty acid synthase,and the related proteins of VLDL-formation were decreased,but there were no changes in hepatic secretion of apoB100 and hepatic lipids.The hepatic secretion of apoB48 was increased by 35.07% (P<0.05) 6 d after Ad-CRE injection.Conclusions Acute depletion of hepatic insulin receptor might reduce VLDL-TG secretion in manner of time-dependent,and increase the assembly and secretion of smaller apoB-containing lipoproteins in mice liver,which is probably associated with decreased lipogenesis.
