·AlM: To investigate the distribution and related factors of corneal spherical aberration in the age-related cataract patients, and to provide a scientific basis for the application of aspheric intraocular lens ( lOL ) in cataract surgery patients.
· METHODS: Retrospective study of 509 age -related cataract patients of 610 eyes in our hospital. Corneal spherical aberration, corneal curvature, corneal astigmatism and corneal Q -value were examined by iTrace visual function analysis. Statistical software SPSS16.0 was used to analyze statistically.
· RESULTS: The range of corneal spherical aberration was 0 ~1.800μm. The mean coefficient of corneal spherical aberration was 0.266 ±0.010μm. Corneal spherical aberration was no significantly correlation with age, corneal curvature, corneal astigmatism ( r =0.71, 0.56, 0.93, P>0.05 ). There was positive correlation between corneal spherical aberration and Q-value ( r=0.086, P=0.03).
· CONCLUSlON: Corneal spherical aberration varied greatly among age-related cataract patients.The choice of asphericity intraocular lens should be a matter of personal choice.

OBJECTIVETo summarize and analyze the compatibility laws for acupoint selection of acupuncture in treating diabetic gastroparasis (DGP) in modern literatures of clinical researches.

METHODSRetrieved were literatures related to treating DGP by acupuncture or acupuncture combined other therapies from PubMed, CNKI, and WF from 1982 to 2014. Analyzed were frequency of acupoint use, meridians selected acupoints belonged to, regions selected, association laws of selected compatible acupoints.

RESULTSRetrieved were 35 with compatibility frequencies more than 15 listed as follows: compatibility frequency of Zusanli (ST36) and Zhongwan (CV12) was 33 (94.29%); compatibility frequency of Zusanli (ST36) and Neiguan (PC6) was 23 (65.71%), compatibility frequency of Zhongwan (CV12) and Neiguan (PC6) was 22 (62.86%), compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Neiguan (PC6) was 22 (62.86%); compatibility frequency of Zusanli (ST36) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zhongwan (CV12) and Sanyinjiao (SP6) was 16 (45.71%); compatibility frequency of Zusanli (ST36), Zhongwan (CV12), and Sanyinjiao (SP6) was 15 (42.86%). Meridians selected acupoints belonged to were sequenced as Foot Yangming Stomach channel, Ren channel, Foot Taiyang Bladder channel, and so on. Acupoints selected were mainly in lower limbs, chest and abdomen, waist and back. The compatibility of Zusanli (ST36) and Zhongwan (CV12) was the most often used with the highest frequency.

CONCLUSIONSThe compatibility laws for acupoint selection of acupuncture in treating DGP were mainly dominated as upper-lower selection, three regions selection, local selection, anterior-posterior selection. The compatibility laws for acupoint selection of acupuncture along meridians were mainly dominated as the convergence points and exterior-interior meridian points.

Objective To improve the awareness of fetal cardiac rhabdomyomas (CRs) and investigate a better model for prenatal diagnosis and treatment through analyzing imaging findings and prognosis.Methods A retrospective study was conducted on 23 cases of CRs which were diagnosed by ultrasound in Obstetrics and Gynecology Hospital of Fudan University from January 2008 to November 2015.General conditions,imaging features,prognosis and follow-up data of the 23 cases were described.Results The average gestational age of the 23 fetuses at diagnosis was (29.8±4.1) (22.4-35.7) weeks.Seventeen out of the 23 gravidas received prenatal multidisciplinary consultation.Among all 23 gravidas,three (13％) were lost to follow-up,12 (52％) decided to terminate the pregnancy,and the other eight (35％) continued to term pregnancy and their babies were followed up for three years.Of these eight cases,two cases received prenatal brain MRI and no tuberous sclerosis complex (TSC) was detected,no CRs was identified during the follow-up,and their physical and mental developments were both normal.One case was diagnosed with suspected subependymal nodules by prenatal brain MRI in our hospital,but the MRI images was normal when scanned in the other hospital,and follow-up data revealed neither CRs nor abnormal physical and mental developments.Four cases did not received prenatal brain MRI,but the MRI images of neonatal brains indicated TSC,besides,follow-up data showed that seizures were observed,physical developments were all normal,but three of the four cases had mental retardation;CRs disappeared in only two of the four cases.One case had neither prenatal nor neonatal MRI,but follow-up data showed that CRs had disappeared and physical and mental developments were both normal.Conclusions Prenatal diagnosis of fetal tuberous sclerosis is crucial to the prognosis of CRs.Prenatal ultrasonography in combination with cranial MRI improves the accuracy of prenatal diagnosis of CRs complicated with TSC and assists in clinical decision-making and prognosis analysis.

[ ABSTRACT] AIM:To investigate the effect of silencing cell division cycle 25a ( CDC25a) gene on the prolifera-tion of human hepatoma HepG2 cells.METHODS:CDC25a gene in human hepatoma HepG2 cells was silenced by RNA interference.Real-time PCR was applied to detect the expression of CDC25a, cyclin E and CDK2 at mRNA levels in the HepG2 cells.Western blotting was applied to detect the expression of CDC25a at protein level.In addition, MTT assay, Giemsa staining and flow cytometry were used to measure the proliferation of human hepatoma HepG2 cells.RESULTS:The expression of CDC25a at mRNA and protein levels in RNA silence group was lower than those in negative control group and normal control group (P<0.05).The mRNA expression of cyclin E and CDK2 in silence group was lower than that in negative control group and normal control group (P<0.05).The cell proliferation in silence group was lower than that in negative control group and normal control group ( P<0.05) .The results of flow cytometry revealed that the cells in silence group were blocked in G1 phase.CONCLUSION:Infection of LV-CDC25a-RNAi recombinant to the HepG2 cells effec-tively inhibits the CDC25a gene expression and the proliferation of human hepatoma cells, and arrests the cells in G1 phase, suggesting that CDC25a gene may be a key target for the treatment of liver cancer.

BACKGROUND:From the biological structure, the posterior cruciate ligament is surrounded by the synovial folds of posterior capsule, arising from the inner side of the medial femoral condyle to the posterior part of tibial intercondyloid spine. The main traditional treatment method for posterior cruciate ligament tibial avulsion fracture is open operation, but it is difficult in anatomic reduction, cannot ful y restore knee joint stability and has a great negative impact on the normal function of posterior cruciate ligament. OBJECTIVE:To investigate the effects of arthroscopic implant internal fixation in the treatment of tibial avulsion fracture of the posterior cruciate ligament. METHODS:120 patients with tibial avulsion fracture of the posterior cruciate ligament were randomly assigned into treatment group and control group, with 60 cases in each group. The control group was given the traditional open surgery, and the treatment group was given the arthroscopic surgery. After 3 months, International Knee Documentation Committee (IKDC) scores and Lysholm scores were detected in the two groups;the knee joint range of motion was determined before and 3 months after treatment. RESULTS AND CONCLUSION:Wounds were healed at stage I in al patients with no serious complications. There was no difference in the knee joint range of motion between the two groups before treatment, but the range of motion was increased significantly in both two groups at 3 months after treatment (P<0.05), meanwhile which was higher in the treatment group than the control group (P<0.05). At 3 months after treatment, the excel ent knee function rate was significantly higher in the treatment group (97%) than the control group (88%) according to the Lysholm scores;the IKDC scores were significantly higher in the treatment than the control group in terms of claudication, support, pain, swel ing, and squat (P<0.05). These results indicate that the arthroscopic implant fixation of tibial avulsion fracture of the posterior cruciate ligament has better short-term effects to promote recovery of knee joint function, but no serious complications.

Objective To investigate the correlation between enlarged perivascular space (EPVS) and post-stroke depression (PSD) in patients with ischemic stroke. Methods Consecutive patients with acute cerebral infarction admitted to hospital from March 2010 to March 2014 were enroled prospectively. The patients completed head MRI examination after admission and performed EPVS grading. At 3 months after symptom onset, they performed PSD assessment according to Hamilton Depression Scale (HAMD) and Classification and Diagnostic Criteria of Mental Disorders in China, 3rd edition (CCMD-3). The relationship between EPVS and PSD was analyzed. Results A total of 249 patients were enroled; including 62 patients (4. 9% ) experienced PSD at 3 months. There were significant differences in the proportions of the EPVS classification patients of the baseline National Institutes of Health Stroke Scale score ( the median [interquartile range]; 4 [3 - 6] vs. 3 [2 - 5]; Z = - 2. 950, P = 0. 003), centrum semiovale (χ2 = 14. 370, P = 0. 001), and periventricular (χ2 = 11. 590, P = 0. 003)between the PSD group and the non-PSD group. Multivariable logistic regression analysis showed that centrum semiovale EPVS grade 2 (odds ratio [OR] 3. 89, 95% confidence interval [ CI] 1. 59 - 9. 56) and grade 3 (OR 3. 28, 95% CI 1. 04 - 10. 33) were significantly correlated with PSD; periventricular EPVS grade 2 (OR 0. 72, 95% CI 0. 27 - 1. 91) and grade 3 (OR 2. 24, 95% CI 0. 68 - 7. 37) were not correlated with PSD. Conclusions Centrum semiovale EPVS is independently associated with PSD, and periventricular EPVS is not.

Objective Comparing the dosimetric characteristics of volumetric modulated arc therapy (VMAT) and constant dose rate intensity modulated arc therapy (IMAT) in esophagus cancer to evaluate the performance of the two different arc therapy delivery techniques.Methods 22 cases of esophageal cancer patients were selected for the planning comparison study.All plans were done for IMAT and VMAT treatment plans on Oncentra 4.1 treatment planning system,prescription dose of 2 Gy in total 30 fractions.Planning objectives for PTV were at least 95％ reached the prescription dose and V110 no more than 10％.The maximum dose of spinalcord below 45 Gy and double lung dose V20 ≤ 28％,V30 ≤ 18％ were constrained.Plans were evaluated based on the ability to meet the dose volume histogram.The dose homogeneity index (HI),radiation conformity index (CI),radiation delivery time,monitor units and γ pass rate were also compared.SPSS 19.0 software paired ttest analysis was carried out on the two sets of data.Results The results showed that the IMAT plans in terms of the PTV's CI (t =3.35,P=0.003),D2(t =-2.27,P=0.034) lung's V30(t =-2.46,P=0.023) were better than that of VMAT group.But the VMAT plans spinal's V40 (t =2.37,P =0.027),lung's V5 (t =2.43,P =0.024) were superior to that of IMAT plans.There were no significant differences between IMAT and VMAT plans in the average dose of PTV,CTV,GTV,heart,spinal cord,double lung and the γpass rate.Conclusion IMAT presents a slight improvement in the OAR sparing in high dose with shorter treatment time when compared to VMAT.While in terms of delivered MU and tissue of low dose irradiated area is higher than that of in VMAT.These two treatment methods all can meet the clinical demand,which should be selected according to the actual situation of the patient.
