AlM: To comprehensively evaluate of visual quality after epipolis laser in situ keratomileusis ( EPl-LASlK) in mild to moderate myopia.METHODS: Sixty cases ( 120 eyes ) undergone EPl-LASlK with equivalent diopter ( SE ) were divided into two groups:mild myopia group (60 eyes) and moderate myopia group ( 60 eyes ) . Objective visual acuity, aberration, contrast sensitivity and glare sensitivity were measured before and 1wk; 1, 6mo after operation, and made comparative analysis. RESULTS: Postoperative uncorrected visual acuity ( UCVA ) of two groups were better than that of preoperative(P<0. 05). Postoperative 6mo, there were significant differences on total high RMS between two groups ( P < 0. 05 ). Before operation and 6mo after operation, higher - order aberrations had statistically significant difference between two groups (P<0. 05). After 1wk and 1mo, there were statistical significances at the five frequencies between two groups (P<0. 05). After 6mo, the mild myopia group returned to preoperative levels, however, moderate myopia group in the high frequency region ( 18. 0c/d ) had significant difference with before surgery (P<0. 05). 1wk after surgery, there were statistically significant differences on the 3. 0, 6. 0, 12.0, 18. 0c/d frequency in both groups (all P<0. 05), 1mo after surgery, there were significant difference at 12.0, 18.0c/d frequencies (all P<0.05), after 6mo, both groups returned to preoperative levels, showed no significant difference.CONCLUSlON:Visual quality is poorer in mild myopia patients than that in moderate myopia at early stage after EPl-LASlK. Better visual quality is observed at mid-late stage.

Objective To explore the preventive and therapeutic effects of diminazene (DIZE) on pulmonary arterial hypertension (PAH) in rats.Methods Left pulmonary lobectomy combined with injection of monocrotaline was used to establish a rat model of pulmonary arterial hypertension.One hundred adult male Wistar rats were randomly divided into blank control group (group A,n=20),DIZE control group (group B,n=20),PAH model group (group C,n=20),PAH model plus DIZE group (group D,n=20) and PAH model plus DIZE and C-16 group (group E,n=20).Angiotensin-converting enzyme 2 (ACE2),IL-6 and IL-8 levels were determined by fluorescence resonance energy transfer (FRET) and enzyme linked immunosorbent assay (ELISA),and the mean pulmonary arterial pressure (mPAP) and right ventricular hypertrophy index (RVHI) were measured.The wall thickness (WT) and intimal hyperplasia score were calculated,and the pulmonary vascular lesions were analyzed using elastic fiber staining.Results RVHI,ACE2 enzyme activity and WT in the group A were significantly different from those of the groups C,D and E (P<0.05).Those of the group D and E were significantly different (P<0.05).The five groups showed significant differences in the overall analysis of each index (P<0.05).Conclusions Diminazene can increase the ACE2 enzyme activity,and decrease the mPAP,RVHI and WT,while reducing the pulmonary arterial medial hypertrophy,and inhibit intimal hyperplasia of pulmonary arterioles.The results of this study provide an experimental basis for the use of diminazene in the treatment of human pulmonary hypertension.

Objective To evaluate the curative effect of stereotactic radiotherapy in pancreatic cancer in the elderly. Methods Retrospectively analyzed 65 elderly patients with pancreatic cancer were treated with stereotactic radiotherapy. The ages of patients were 60 to 86, with mean age of 71 2. The numbers of treatment were 8 to 12 times according to the tumor size and patients condition Fractional dose were 3 to 6 Gy, total dose were 32 to 54 Gy. The curve of isodose was 50%～80% Results The patients average alive time was 9 3 months after stereotactic radiotherapy The clinical benefit response rate was 61 2%. The CR+PR was 38 4% Conclusions The stereotactic radiotherapy is safe and effective method for treating elderly pancreatic cancer

Objective To study the correlation between the blood selenium level and glutathione peroxidase(GSH-Px)with the occurrence of gestational diabetes mellitus(GDM).Methods Among 1 360 pregnant women in our hospital from January 2011 to December 2012,68 cases GDM were diagnosed as GDM (observation group)and other 113 non-GDM pregnant women were ran-domly selected from these 1360 pregnant women as the control group.The serum selenium level and GSH-Px activity were com-pared between the two groups.Results The selenium level and GSH-Px activity in the control group were higher than those in the observation group.The selenium level was (3.07±0.51)mmol/L in the control group and (2.06±0.41)mmol/L in the observa-tion group,respectively;the GSH-Px activity was (197.23±18.73)U in the control group and (151.35±19.67)U in the observa-tion group,the differences between the two groups were statistically significant (P <0.05).Conclusion The decrease of serum se-lenium level and GSH-Px activity may be one of the pathogenic causes of GDM.

[Objective] To observe the effects of Oysters, Abalone shel , Concha arcae, Mother-of-pearl, Concha cypraeae, Clamshel , these six testacean TCM on the goiter rats. [Method] 72 healthy SD rats were randomly divided into nine groups:normal group, model group, positive group and six testacean TCM groups. Rats were given daily propylthiouracil (0.15 g·kg-1), continuous modeling for 10d, weighing thyroid wet weight,assaying T3, T4 and TSH contents in serum by ELISA, observing the morphological changes of thyroid under light microscope. [Result] Rats in the model group compared with normal group in-creased the relative weight of thyroid, reduced the content of T3,T4, and there was a significant difference( P<0.01), thyroid fol icular epithelial cellhyperplasia was obvious;compared with the model group, Oysters and Clamshel group made the content of T3,T4 in rat rebound, and there was a significant difference (P<0.05);Oyster and Clamshel group’s thyroid fol icular cellhyperplasia were not obvious, while the hyperplasia had different levels for the other 4 kinds of testacean TCM. [Conclusion] Oysters and Clamshel were better to improve the thyroid function of the goiter model rats.

OBJECTIVE: To explore the pathological changes of lower extremity arteries of patients with metabolic syndrome. METHODS: Fifty patients with metabolic syndrome (MS) and 30 normal volunteers were included in this study. The inner diameters, peak systolic velocities and intima-media thicknesses of the lower extremity arteries, and the sizes and numbers of the plaques in the lower extremity arteries were obtained with color Doppler ultrasound (CDU). RESULTS: In the fifty MS patients, the intima-media thicknesses of forty-one were thicker than 1.1 mm and thirty-three had plaques which had brought stenosis in different degrees. The intima-media thicknesses of the common femoral, popliteal and posterior tibial arteries in the MS patients were significantly thicker than those in the normal volunteers (P<0.01 or P<0.05), and a greater number of plaques in the lower extremity arteries were observed in the patients, as compared with the normal volunteers (P<0.01). CONCLUSION: Various pathological changes had taken place in the lower extremity arteries of the MS patients. The sites and degrees of the lower extremity arterial diseases in MS patients can be definitely detected with CDU.

Objective To analyze the curative effects of total knee arthroplasty(TKA)for severe genu varus combined with flexion deformity.Methods The clinical data of 25 patients(36 knees),who had undergone TKA for severe genu varus combined with flexion deformity from January 2005 to October 2010,were retrospectively analyzed.There were 7 males and 18 females,aged from 55 to 80 years(average 70.5 years).The primary diseases were osteoarthritis in 22 cases and rheumatoid arthritis in 3 cases.HSS knee score was used before and after the operation to assess the efficacy of the TKA.Results All of the patients were followed up for 4 to 9 years(average 6 years).The degree of flexion deformity was reduced from (21 ±63)°to(1.1 ±2.3)°;the degree of the varus decreased from(210 ±4.8)°to(175.6 ±2.1)°;range of motion of the knee joint increased from(70.5 ±20.5)°to(115.1 ±5.3)°;knee score augmen-ted from(33.2 ±10.5)to(90.7 ±8.5);function score added from(35.5 ±14.2)to(85.6 ±10.5);there were 21 cases(8 knees)rated as excellent,2(3 knees)as good and 2(3 knees)as fair,and the excel-lent and good rate was 86%.Most of the patients had normal force line of the knee joint,but 2 patients re-mained varus deformity of 5°~10°.Conclusion Satisfying outcome can be achieved by TKA in treating severe genu varus combined with flexion deformity of the knee.
