Primary hepatic carcinoma is one of the high incidence malignant tumors and the mortality ranked the second in the death caused by malignant tumors in China. The research progress on the epidemiology of primary hepatic carcinoma, the related environmental factors(virus, parasite, bacterium infected, aflatoxin ingested, drinking water pollution, smoking and drinking alcoholic beverages) and genes were reviewed and the mechanism of primary hepatic carcinoma was discussed in the present paper.

?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 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.

Objective To assess the serum CA125 in literatures of ovarian neoplasms based on evidence-based medicine.Methods The relating reports published in the years of 1996—2003 were collected and evaluated according to the evidence-based medicine principles. Main outcomes include design methods,sample screening,establishment of control group,blind method,criteria of diagnostic trials.Results In the reports collected, gold standard was adopted in 62 reports and independent blind method was adopted in 23 reports, criteria of diagnostic trials such as sensitivity, specificity and likelihood ratio were incomplete and there was no descriptions okf potential bias controlling. As for the literatures sharing the same method ,their conclusion did not totally accord with each other.Conclusion There is no evidence to implicate that serum CA125 was considered an independent predictor of the diagnosis of ovarian cancer.

Objective To evaluate the clinical efficacy of China-made expanded polytetrafluoroethylene (ePTFE) in the treatment of facial defects and hollow deformities on the face. Methods Facial augmentation was performed in different sites as the forehead, temple, nose, chin, nosal base and maxilla, respectively, to correct the facial defects and hollow deformities, by using either China-made ePTFE (Experimental Group) or imported ePTFE (Control Group). Postoperative parameters between the two groups were compared. Results The Experimental Group included 16 patients (18 sites), in whom the postoperative follow-up was conducted for 6~9 months. In this group, a secondary infection (in the nose) occurred in 1 patient because the implant was placed too superficially and too close proximity to the incision, and the implant was removed out. Delayed healing of the incision (in the chin) with uncovered implant was found in 1 patient, who was cured by the change of dressing. In the rest of the patients, no obvious allergic, inflammatory or rejection reaction was seen and a good cosmetic result was achieved. The satisfactory rate of this group was 94.4%(17/18). The Control Group included 10 patients (20 sites). The implant was found bared and then removed in 1 patient (in the nose). The satisfactory rate of this group was 91.7%(11/12). There were no statistical differences between the two groups in the wound healing ( ? 2 =1 109, P =0 574), the adverse reaction ( P =1 000), and the clinical efficacy ( P =1 000). Conclusions China-made ePTFE gives histocompatibility as good as imported one. It is suitable for filling the soft tissue and can be used as a safe and economical alternative.

Aim To assess the effect of heat shock factor-1(HSF1)and heat shock protein 70(HSP70)to tachyphylaxis by bradykinin in the opening blood-tumor barrier(BTB).Methods The C6 rat intracerebral glioma model was constructed by stereotactic implantation technique.Using western blotting method to continue monitoring the protein expression of HSF1 and HSP70 in tumor tissue after bradykinin acted on animals.The expression of occludin in tumor tissue were detected by immunohistochemistry method.Using Evans blue and electron microscope,respectively,detected the permeability and pathology of BTB after intracarotid infusion of bradykinin in C6 rats.Results Bradykinin increased the tight junction opening and the permeability of BTB in C6 animals,and the relative increments of EB were 5.19 ?g?g-1(0 min),5.06 ?g?g-1(5 min),11.35 ?g?g-1(10 min,P

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.
