Chinese Journal of Postgraduates of Medicine 2010;33(26):26-28
Objective To compare the long-term effects between procedurefor prolapse and hemorrhoids(PPH) and Milligan-Morgan hemorrhoidectomy( MMH ) in the treatment of Ⅲ and Ⅳ degree of hemorrhoids. Method The clinical data of 43 cases with Ⅲ and Ⅳ degree hemorrhoids received PPH (PPH group)and 71 cases received MMH (MMH group) were analyzed retrospectively from October 2001 to July 2003. Results Late bleeding in 5 cases of PPH group and no one of MMH group (P <0.05).Hemorrhoidal recurrence prolapsed in 9 cases of PPH group and 5 cases of MMH group (P < 0.05). The rectal neck pressure preoperative,after 6 months, 1 year and 3 years were (122.0 ± 11.3), (90.0 ± 10.4),(103.0 ± 13.8) and (113.0 ± 11.2) cm H2O (1 cm H2O =0.098 kPa) of PPH group,after 6 months was decreased obviously than preoperative (P<0.05),and they were ( 126.0 ± 13.5), (91.0 ± 12.4), (78.0 ±9.8) and (81.0 ± 7.5 ) cm H2O of MMH group,after 6 months, 1 year and 3 years were decreased obviously than preoperative (P < 0.05). Conclusion PPH is safety and effect at short time,but it brings more late bleeding and anal pain,and its rate of prospective hemorrhoidal recurrence is more higher than MMH.

4.Corneal high order aberrations in adults with myopia:correlations with myopic degree and keratometry
International Eye Science 2016;16(6):1043-1047
?AIM: To investigate the corneal high order aberrations in adults with myopia and to study its correlations with myopic degree and keratometry.?METHODS: A total of 63 patients ( 126 eyes ) from the ophthalmology department of our hospital were included in this study during May 2014 to June 2015. Visual acuity, intraocular pressure ( IOP ) , diopter, slit lamp examination, central corneal thickness ( CCT ) , funduscopic examination, corneal topography and corneal total higher order aberrations ( THOAs ) were recorded. Right eye was selected. According to the spherical equivalence ( SE) , 63 eyes were divided into two groups, the mild to moderate myopia group (M-M group, SE<-6. 00D) and the high myopia group (H group, SE≥-6. 00D). The correlations of corneal THOAs with diopter, keratometry, IOP and CCT were analyzed. Kolmogorov-Smirnov Test was used for normality test. Independent-samples t test was used for comparison between two groups. Pearson correlation analysis was for comparison between two continuous variables.?RESULTS: Z44 was found a statistic difference between the M-M group and H group (t=2. 51,P=0. 02). IOP was negatively correlated with Z5-3(r= -0. 52,P=0. 01), and CCT was positively correlated with Z4-4(r=0. 43,P=0. 03) in H group. There was no correlation between higher order aberrations and SE in M-M group ( all P>0. 05 ) Total coma aberration ( TCA ) was negatively correlated with SE (r=-0. 57,P=0. 002) and spherical degree (Sph, r=-0. 55,P=0. 003) in H group. Z40 was positively correlated with average K (AK) (M-M group:r=0. 40,P=0. 02. H group:r=0. 55, P=0. 03), K steep (Ks) (M-M group:r=0.39, P=0.02. H group:r=0.51, P=0.01) and K flat (Kf) ( M-M group:r=0. 40, P=0. 02. H group:r=0. 57, P=0. 01) in both groups. Z53was negatively correlated with Ks(r=-0.4, P=0. 04) in H group.?CONCLUSION: The THOAs parameters are influenced by diopter and keratometry. TCA is negatively correlated with SE and Sph in patients with high myopia, and spherical aberration is positively correlated with keratometry.

Objective To evaluate the effect of TBL (team-based learning) method in pharmacology teaching for the foreign students of clinical medicine. Methods In the course of pharmacology teaching of the foreign students of clinical medicine, TBL method was performed in the 2012-year students and tradi-tional teaching method was performed in the 2011-year students. After the teaching, students' grades in the ordinary performance, their final exam scores and their evaluation of the two teaching methods were com-pared. Graph pad 5 was used to analyze the data and the t test was performed. Results The average ordi-nary performance of the students with TBL was significantly higher than that with the traditional teaching [(84.94 ±12.66) vs. (72.30 ±4.90), P=0.000] and the final examination scores were significantly im-proved [(74.00±6.76) vs. (69.00±6.20), P=0.023]. The survey showed students were more satisfied with the TBL teaching mode than traditional teaching mode [(8.40±0.71) vs. (7.12±1.07), P=0.000]. Conclusion TBL teach-ing mode can effectively improve the pharmacology teaching effect of foreign students.

Objective To observe the expression of TGF?RⅠ,TGF?RⅡ and Smad7 in oxazolone-induced colitis of mice and to investigate the role of the TGF? signal transduction on pathogenesis of colitis. Methods Balb/c mice were pre-sensitized by skin painting with 0.2 ml 3% oxazolone on day 0 and 1 followed by intrarectal administration of 0.15 ml 1% oxazolone on day 7. The mice were sacrificed after 3 days. Colitis was evaluated by macroscopic and microscopic examination. The expressions of TGF?RⅠ, TGF?RⅡ and Smad 7 were examined by immunohistochemical study and Western blot respectively. All the results were compared with the controls. Results Twenty-four hours after intrarectal administration of oxazolone, the mice presented anorexia, less moving, loose stool, hematochezia or occult blood(+) and weight loss. The macroscopic and microscopic scores in two groups were 0.17?0.41, 2.67?1.03 and 2.33?0.52, 8.17?0.75, respectively. In the normal intestine, TGF?RⅠ, TGF?Ⅱ and Smad7 were mainly co-localized on the upper part of the villus. However, their expression was not only throughout the villus including fundus of crypts, but also in the mononuclear cells of the lamina propria and submucosa in the experimental intestine. The amounts of TGF?RⅠ, TGF?Ⅱ, Smad7 and the ratio of TGF?RⅠ/Ⅱ in control and colitis groups were 3.40?1.25, 21.71?6.97, 8.95?2.12, 0.16?0.01 and 6.49?3.18, 4.40?3.34, 17.92?6.80, 2.14?1.61, respectively. Conclusions Decreased TGF?RⅡ and increased Smad7 expressions indicate the abnormality of TGF? signal transduction in oxazolone-induced colitis. These pathologic and immunologic characteristics may resemble human ulcerative colitis.
