OBJECTIVE: To prepare paclitaxel loaded D-α-tocopheryl polyethylene glycol 1000 succinate(TPGS)-modified carboxymethyl chitosan-rhein polymeric micelles (PTX/TPGS-CR PMs) and preliminarily evaluate their performance. METHODS: PTX/TPGS-CR PMs was prepared by dialysis method, and the preparation procedure of PTX/TPGS-CR PMs was optimized by single factor with the drug loading, encapsulation rate and particle size as the indicators, then the optimized preparation procedure was verified. The safety of PTX/TPGS-CR PMs was initially investigated by the hemolysis test and the vascular irritation test. The cytotoxicity of PTX/TPGS-CR PMs in Hela cells was studied by MTT assay. Cell uptake experiments were performed by laser confocal microscopy and flow cytometry to investigate the uptake of PTX/TPGS-CR PMs by Hela cells. RESULTS: The particle size and PDI of PTX/TPGS-CR PMs prepared by the optimized preparation were (197.3±4.4) nm and (0.131±0.021), respectively. The Zeta potential was (-31.8±0.5) mV. The drug loading and encapsulation efficiency were (48.20±3.03)% and (87.26±4.91)%, respectively. The hemolytic test results showed that the hemolysis rate was less than 1.71%. No obvious irritation was observed after intravenous injection. The cytotoxicity of PTX/TPGS-CR PMs in Hela cells was concentration-and time-dependent. Cell uptake experiments showed that PTX/TPGS-CR PMs could be efficiently uptake by Hela cells. CONCLUSION: The PTX/TPGS-CR PMs has high drug loading and encapsulation efficiency, good safety. And they exhibite slightly better antitumor activity in vitro than Taxol®.

Objective To explore the relationship between age and refractive predictability of excimer laser in situ keratomileusis (LASIK)for the correction of myopia.Design Retrospective case series.Participants 362 patients(703 eyes)who had performed LASIK.Methods According to the age,patients were divided into four groups(≤30y,31～34y,35～39y and≥40y).Their preoperative and postoperative refractive powers examined with automatic refactor as well as manifest optometry were analysed and followed up from 6 months to 2 years.According to pre-operative refractive power,patietns were divided into low and moderate myopia group(≤-6.00D), high myopia group(-6.25～-12.00D)and super-high myopia group(≥-12.25D).The eyes with refractive power at post-operative 2 years≥-1.00D were regressive eyes.Main Outcome Measures Refractive error before surgery,intended residual refractive power and 3,6, 12, 24 months post-operative refractive powers.Results There were no significant differences between intended residual refractive powers and refractive powers at post-operative 6 month in 3 groups(

Objective In order to cure some patients with the following characteristics which appear only when smiling: elevation and shortening of the upper lip, a transverse furrow below the co-lumella, and increased exposure of the maxillary gums, we reported a new surgical procedure to cor-rect this deformities. Methods By means of a transfixion incision extended laterally along the vestibu-lar or the upper gingivolabial sulcus incision, part of the depressor septi and orbicularis muscle were excised, and extensive separation were made to lower the upper lip. Results 27 cases of short upper lip were treated. Among the total, the transfixion incisions were made in 9 cases, and the upper gingi-volabial sulcus incisions were made in 18 cases. These procedures achieved lowering the upper lip, lighting or disappearing the transverse furrow, and covering the exaggerated exposure of the gums when patients smiled. At the same time the rhinoplasties were done in 6 cases. Through the above-mentioned we were able to correct the deformities on rhino-gingivolabial part only when the faces moved, achieved some kind of beauty for patients, and obtained satisfactory results. Conclusions Some patients have added defects .that are exported only when they begin to make facial movements. The cause of these characteristics is hypertrophy of the depressor septi nasi muscles. We describe the technique that is not only to correct the defects but also to enhance the patient's smile. It is worth to recommend for clinical application.

Objective To investigate the clinicopathological significances of LDHA/mutant p53 co-expres-sion in gliomas. Methods According to the 2016 WHO CNS,archived 68 gliomas were collected and analyzed retrospectively. The co-expression of LDHA/mutant p53 was detected by immunohistochemical staining. Results High expression of LDHA alone was always found in high grade gliomas(48.5%). Mutant p53 high expression was usually observed in glioblastomas (26.5%). There was a close relationship between co-expression of LDHA/mutant p53 in glioblastoma(27.9%,P = 0.005),or gliomas with high histological grading(27.9%,P = 0.002). Conclusions Co-expression of LDHA/mutant p53 in tumor cells might be a specific immunohistochemical pheno-type of gliomas,and may help for distinguishing glioblastoma and other high grade gliomas from low grade gliomas.

[Objective]To explore the possible effects of the apolipoprotein A5(APOA5)gene rs2075291 and rs3135507 poly-morphisms on plasma lipid levels and the severity of coronary stenosis in patients with coronary heart disease(CHD)in Chinese Han people.[Methods]Polymerase chain reaction-restriction fragment length polymorphism method(PCR-RFLP)was used to identify the genotypes of the rs2075291 or rs3135507 polymorphism for the 324 patients with CHD and the 152 CHD-free controls,and the lipid levels between the genotypes were compared. The severity of coronary stenosis was assessed by the Gensini scoring system ,and the associations of the rs2075291 and rs3135507 polymorphisms as well as other factors with the Gensini scores were analyzed by mul-tivariate linear regression.[Results]The CHD patients had higher prevalence of hypertension ,and higher levels of triglycerides (TG),total cholesterol(TC),apolipoprotein B100(APOB100),lipoprotein(a)[Lp(a)],TG/high-density lipoprotein cholesterol (HDL-C),TC/HDL-C,low-density lipoprotein cholesterol(LDL-C)/HDL-C and APOB100/apolipoprotein AI(APOAI),and low-er levels of HDL-C and APOAI than the controls(P < 0.05 for all). The rs2075291 or rs3135507 allele and genotype frequencies were similar between the CHD group and the control group. The subjects with the rs2075291 GT genotype had higher levels of TG and TG/HDL-C,and lower levels of HDL-C than the subjects with the GG genotype in controls(P < 0.05 for all). In CHD patients, those with the rs2075291 GT genotype had higher levels of TG/HDL-C and TC/HDL-C than the patients with the GG genotype(P<0.05 for both). Regarding the rs3135507 polymorphism,the A allele carriers had lower level of APOB100 than the patients with the GG genotype(P<0.05). No significant association between the rs2075291 or rs3135507 polymorphism and the Gensini scores were detected by multivariate linear regression(P > 0.05).[Conclusion]The APOA5 rs2075291 polymorphism had significant effects on plasma lipid levels,but no effects on the occurrence and development of CHD. Further multicenter case-control studies with large samples are needed to validate these findings.

Objective: To observe the effect of acupuncture plus thunder-fire moxibustion on the expressions of matrix metalloproteinase-3 (MMP-3), tissue inhibitor of metalloproteinase-1 (TIMP-1) and transforming growth factor-β1 (TGF-β1) in cartilage of knee osteoarthritis (KOA) rats, and to explore the mechanism of acupuncture plus thunder-fire moxibustion in the treatment of KOA. Methods:Thirty Sprague-Dawley (SD) rats were randomly divided into a blank control group, a model group and an acupuncture-moxibustion group by random digits table, 10 rats in each group. Rats in the model group and the acupuncture-moxibustion group were injected with papain in the right posterior knee joint to prepare the models. The levels of MMP-3 and TIMP-1 in rat synovium of each group were measured by enzyme-linked immunosorbent assay (ELISA) after 2 weeks of treatment. The level of TGF-β1 was determined by Motic B5 Micro-camera system. Results:The levels of MMP-3 and TIMP-1 in the cartilage of the model group were significantly higher than those in the blank control group (allP<0.01); the levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were lower than those in the model group, and the between-group differences were statistically significant (all P<0.05). The levels of MMP-3 and TIMP-1 in the acupuncture-moxibustion group were higher than those in the blank control group, and the differences were statistically significant (all P<0.05). The level of TGF-β1 in cartilage tissues of the model group was significantly lower than that in the blank control group (P<0.01); the level of TGF-β1 in the acupuncture-moxibustion group was higher than that in the model group (P<0.05), but it was lower than that in the blank control group, and the between-group difference was statistically significant (P<0.05). Conclusion: Acupuncture plus thunder-fire moxibustion can effectively recover the abnormal expressions of MMP-3 and TIMP-1 in KOA model rats and somewhat up-regulate TGF-β1, which may be one of its mechanisms of acupuncture plus thunder-fire for KOA.
