AlM:To observe clinical effects between the laser in situ keratomileusis ( LASlK ) surgery and the laser subepithelial keratomileusis ( LASEK ) surgery as the second operation after an unsuccessful LASlK surgery.METHODS:Forty-nine patients (98 eyes) with refractive regression after LASlK operation received the second surgery. All patients were divided into two groups:group A and B. Group A (48 eyes of 24 patients) received LASlK surgery and group B ( 50 eyes of 25 patients ) received LASEK surgery. lnspect the main parameters included visual acuity, refraction, corneal curvature, and the total value of high-aberration after 1wk, 1mo and 1a, t-test of groups was used as statistical analysis method.RESULTS: There was statistically significant (P<0. 05) between the two groups in visual acuity after 1wk. There was no statistically significant between the two groups in visual acuity after 1mo, and there was also no statistically significant between the two groups in visual acuity, average spherical equivalent refractive degree, average corneal curvature, and the total value of high-aberration after one year (P>0. 05). There developed one case of epithelium in growth after LASlK surgery, and one case of haze Ⅱ after LASEK surgery.CONCLUSlON: Both LASlK and LASEK surgery can obtain satisfactory therapeutic results after an unsuccessful LASlK surgery.

BACKGROUND:The effect of body mass index (BMI) on the outcomes ofin vitrofertilization (IVF) is controversial. Some scholars suggested that the higher BMI, the lower rate of pregnancy, and the higher rate of abortion. However, some others got the different results. To data, the effects of BMI on the pregnancy outcomes in females at different ages are rarely reported.
OBJECTIVE:To explore the effect of BMI on the pregnancy outcomes of IVF for infertile women atdifferent ages.
METHODS:A total of 902 cycles undergoing IVF were divided into two groups according to the age:≤ or> 35 years old groups. The patients in each group were then divided into four subgroups according to BMI: low weight, normal weight, excess weight, and obesity subgroups, respectively.
RESULTS AND CONCLUSION: With increasing BMI, the average dosage of gonadotropins was increased gradualy in two both of age groups (P < 0.05). In the≤ 35 years old, the levels of estrogens on the day of injecting human chorionic gonadotropin was significantly lower in obesity group than the other subgroups (P < 0.05); the rates of empty folicle in excess weight and obesity subgroups were significantly higher than that in normal weight subgroup (P < 0.008 23). The fertilization rate and clinical pregnancy rate of in obesity subgroup were significantly lower than those in the other subgroups (P < 0.05). In the > 35 years old group, the empty folicle rate in obesity subgroup was significantly higher than that in normal weight subgroup (P < 0.008 23). Fertilization rate in excess weight and obesity subgroups was significantly lower than that in the normal weight subgroup (P< 0.008 23). There were no significant differences in cleavage rate, cycle cancelation rate, implantation rate, biochemical pregnancy rate and abortion rate between four subgroups (P> 0.05). These findings suggest that in the females at the younger age, BMI not only affects the quality of folicles and fertilization rate; but with increasing BMI, clinical pregnancy rate is decreased obviously. However in the females at the older age, BMI only affects the folicular quality, embryo quality and fertilization rates; there are no significant differences in the outcomes of pregnancy in the four subgroups. BMI have effects on pregnancy outcomes of IVF, and the effects are much greater in the younger female group.

Objective To measure the renal cortex blood flow leVel in Patients with stage 3-4 chronic kidney disease, and to obserVe the effect of Probucol on renal cortex blood flow and renal function. Methods Twenty Patients with stage 3-4 chronic kidney disease in our hosPital were randomly diVided into treatment grouP ( 10 Patients ) and obserVation grouP ( 10 Patients). Ten healthy subjects were chosen as the control grouP. Dynamic sonograPhic tissue Perfusion measurement (DTPM) was used to eValuate the mean flow intensity (Imix),mean flow Velocity (Vmix) and tissue resistance index (TRI) in the three grouPs. Patients in the obserVation grouP were treated with standard theraPy;the treatment grouP was giVen Probucol 500 mg,twice daily in addition to standard theraPy for 6 months. The renal cortex blood flow leVel after treatment was measured in the treatment grouP and obserVation grouP. The serum BUN,SCr,TC,TG,LDL,HDL,hs_CRP,ox_LDL,PA,ALB before and after treatment were measured and comPared between the treatment grouP and obserVation grouP. Results Imix and Vmix were significantly lower,and TRI was significantly higher in the treatment grouP and obserVation grouP than in the control grouP (P<0. 01). After 6 months of treatment,Imix and Vmix in the treatment grouP were significantly increased and TRI significantly decreased as comPared with the baseline and the control grouP (P<0. 01). After treatment,Imix and Vmix were significantly decreased and TRI was significantly increased in the obserVation grouP (P<0. 05). In the treatment grouP,the serum BUN,SCr,TC,TG,LDL,hs_CRP and ox_LDL decreased and PA,ALB and HDL increased after treatment as comPared with the baseline and the obserVation grouP (P<0. 05 or P<0. 01). Conclusion The renal cortex blood flow leVel is significantly lower in Patients with stage 3-4 chronic kidney disease than in the healthy PeoPle. Probucol can imProVe the renal cortex blood flow leVel significantly,Protect the renal function, and imProVe microinflammatory state,nutrition status and dysliPidemia.

Objective To evaluate the change of cellular immunity and its clinical significance in JRA.Methods 7 lymphocyte swbpopulation was analyzed by immunofluorescein and interleukin 2 (IL-2) produced by peripheral blood mononuclear cells in vitro by MTT colorimetric assay. 29 times of various stage with JRA were examined, including 14 clinically active patients, 8 posttreatment or 7 clinically inactive ones. There are 19 healthy children of similar age in control group.Results In active patients, the number of OKT8, OKT4, the ratio of OKT4/OKT8 and the level of IL-2 decreased significantly compared with normal controls. These changes recovered matkedly in remission patients though they did alter affective treatment for (2～4) weeks.Conclusion Patients with active JRA are characterised by aberration of cellular immunity and the aberration reverses obviously slow in comparision with the clinical manifestetions and the routine laboratory investigation.

Local maxima in multimodality image registration based on mutual information is discussed in this paper. Particle swarm optimization (PSO) and filter preprocessing based on hamming window is used to search the registration parameters. Simulations have been done to illustrate that after low-pass filter preprocessing local maxima is eliminated to a great extent. In most case the global maxima can be found by PSO. Simulations illustrate the efficiency and accuracy of this method in registration strategy.

Objective: To explore the relationship between expressions of estrogen (ER) and progesterone (PR) receptors and syndromes of traditional Chinese medicine (TCM) in gastric carcinoma and to establish prognostic indicators for gastric carcinoma. Methods: A total of 72 patients with gastric carcinoma were divided into six groups according to TCM syndrome differentiation. Specimens were collected after operation and ER and PR protein expressions were detected by EnVision immunohistochemical method. Results: The common syndromes in female patients with gastric carcinoma were disharmony between liver and stomach, yin impairment due to stomach heat, and insufficiency of both qi and blood; while in males, interior retention of stagnant toxin, interior retention of phlegm and dampness, and deficiency-cold in spleen and stomach were common. Different TCM syndromes were related with gender (P<0.01), pathology (P<0.01), cell differentiation (P<0.05), infiltration depth (P<0.01), lymphaden metastasis (P<0.05), distant metastasis (P<0.05), and TNM stage (P<0.01). Deficiency and excess syndromes were associated with gender (P<0.05), pathology (P<0.05), tumor location (P<0.01) and TNM stage (P<0.05). The deficiency syndromes were common in female patients. The total positive rates of ER and PR expressions were 8.33% and 37.5% respectively. There was a significant difference in PR expression among different TCM syndromes (P<0.01). PR expression was significantly higher in the syndrome of yin deficiency due to stomach heat than in the other syndromes. The PR expressions in deficiency syndromes were significantly higher than those in excess syndromes (P<0.01). No correlation was found between ER expression and different TCM syndromes. Conclusion: There is a correlation between PR expression and different TCM syndromes in gastric carcinoma.

Objective The aim of this study is to evaluate the safety and efficacy of partial pancreatectomy as part of primary cytoreductive surgery in advanced epithelial ovarian cancer (EOC). Methods A total of 8 patients were recruited in this study who underwent partial pancreatectomy during the primary cytoreductive surgeries for advanced EOC in Fudan University Shanghai Cancer Center from April 2009 to July 2015. Their clinicopathological characteristics, diameter of metastatic tumors, the scope of cytoreductive surgeries, residual diseases after cytoreductive surgeries, postoperative complications and survival situation were retrospective analyzed. Results (1) Clinicopathological characteristics:the median age of these patients was 58 years old(range: 39-63 years old). The median value of preoperative serum CA125 was 1 688 kU/L(range: 119-5 000 kU/L). The median diameter of metastatic tumors involved in pancreatic body or tail was 4.5 cm (range:3-10 cm). All the tumors from the 8 patients were confirmed to be high-grade serous carcinoma. Four patients were staged as International Federation of Gynecology and Obstetrics (FIGO)Ⅳ, and the other 4 patients were staged as FIGOⅢc. (2) Tumor metastases and the scope of cytoreductive surgeries:all of these 8 patients had widely disseminated ovarian cancer, with involvement of upper abdominal, middle abdominal and pelvic cavity. Each patient underwent extensive intra-abdominal cytoreductive surgeries, including hysterectomy, bilateral salpingo-oophorectomy, omentectomy, pelvic periton-ectomy, splenectomy, partial pancreatectomy. Each patient had cytoreductive surgeries of 9.6 different sites on average. Of all 8 patients who underwent partial pancreatectomy, 7 patients had pancreatic tails removed;the other 1 patient had pancreatic body and tail removed. The median volume of blood loss during surgery was 1 350 ml(range:300-3 500 ml), blood transfusion was performed in 7 patients with the median volume of 1 150 ml (range: 500-1 800 ml). (3) Residual diseases after cytoreductive surgeries: optimal cytoreduction was achieved in all patients, with microscopic residual disease in 3 patients, residual tumors diameter < 0.5 cm in 3 patients, and residual tumors diameter between 0.5 and 1 cm in 2 patients. (4) Postoperative complications: 4 patients suffered from complications including pancreatic leakage (2/8), intraperitoneal hemorrhage (1/8) and pancreatic pseudocyst accompanied by infection (1/8). These complications were treated successfully by conservative managements. (5) Survival situation: during the median follow-up duration of 17 months (ranged from 2 to 46 months), 5 patients were still alive until the end of follow-up, including 4 cases under treatment and 1 case survived 29 months without relapse after treatment. Three patients were respectively died in 5, 20 and 46 months after surgery. Conclusion There is a higher risk of postoperative complications of pancreas resection as part of primary cytoreductive surgery in advanced epithelial ovarian cancer, but the resection of pancreatic metastases and part of the pancreas is feasible and necessary.

Objective To investigate the associations of baseline serum uric acid, bilirubin levels with short-term outcome in patients with acute ischemic stroke. Methods The clinical data in successive patients with acute ischemic stroke were colected, including the serum levels of uric acid and bilirubin on admission, the National Institutes of Health Stroke Scale (NIHSS) score, and the modified Rankin scale (mRS) score at discharge or at day14 (mRS 0-2 was defined as good outcome, > 2 was defined as poor outcome). Results A total of 162 patients with ischemic stroke were enroled, including 114 in the good outcome group and 48 in the poor outcome group. There were significant differences in proportions of the patients with diabetes melitus (51. 75% vs. 75. 00% ; χ2 = 7. 526, P = 0. 006), previous history of stroke or transient ischemic attack (TIA) (18. 42% vs. 50. 00% ; χ2 = 17. 790, P = 0. 001), as wel as the baseline diastolic blood pressure (87. 061 ± 12. 245 mmHg vs. 82. 375 ± 10. 949 mmHg; t = 2. 293, P = 0. 023; 1 mmHg =0. 133 kPa), high-density lipoprotein cholesterol (1. 604 ± 0. 299 mmol/L vs. 1. 265 ± 0. 206 mmol/L; t =3. 227, P = 0. 002), fasting glucose (2. 875 ± 0. 438 mmol/L vs. 8. 160 ± 0. 592 mmol/L; t = - 4. 761, P <0. 001), uric acid (289. 365 ± 77. 168 μmol/L vs. 248. 206 ± 66. 206 μmol/L; t = 3. 111, P = 0. 002), total bilirubin (14. 673 ± 2. 213 μmol/L vs. 10. 395 ± 2. 714 μmol/L; t = 3. 779, P = 0. 001 ), direct bilirubin (6. 036 ± 1. 392 μmol/L vs. 4. 956 ± 1. 379 μmol/L; t = 2. 088, P = 0. 038), and indirect bilirubin (8. 634 ± 2. 307 μmol/L vs. 5. 439 ± 1. 223 μmol/L; t = 4. 219, P < 0. 001) levels between the 2 groups. Multivariate logistic regression analysis showed that the previous history of stroke or TIA (odds ratio [ OR ] 3. 751, 95% confidence interval [CI ] 1. 395-10. 091; P = 0. 009) and baseline NIHSS score (OR 2. 723, 95% CI 1. 093-6. 783; P = 0. 031) were the independent risk factors for poor outcome of ischemic stroke; while uric acid (OR 0. 357, 95% CI 0. 141-0. 900; P = 0. 029), high-density lipoprotein (OR 0. 262, 95% CI 0. 079-0. 870; P = 0. 029), and indirect bilirubin (OR 0. 117, 95% CI 0. 025-0. 539; P = 0. 006) were independently correlated with good outcome. Conclusions The increased baseline uric acid and indirect bilirubin levels are the favorable factors for good outcome in patients with acute ischemic stroke.
