Abstract?AlM: To evaluate the efficacy of intravitreal injection with Ranibizumab combined with sub-Tenon injection with Triamcinolone acetonide ( TA ) for macular edema ( ME) due to central retinal venous occlusions ( CRVO) .?METHODS:Forty-six patients (46 eyes) were diagnosed ischemic CRVO with significant macular edema by fundus fluorescence-angiography ( FFA ) and optical coherence tomography ( OCT ) . All the patients had panretinal photocoagulation ( PRP ) , a week after the four times therapies. Twenty-three patients ( 23 eyes ) in group A were randomly chosen to receive intravitreal injection with ranibizumab ( lVR ) , another 23 patients ( 23 eyes ) in group B to treat with both lVR and sub-Tenon injection with TA ( PSTT ) . There was no significant difference on macular edema and best corrected visual activity ( BCVA) between the two groups. The changes in BCVA and central macular thickness ( CMT) before and 1wk; 1, 3, 6mo after treatments were analyzed.?RESULTS: One week after the treatment: the BCVA increased while the CMT decreased compared with that of pretreatment in groups A and B (P<0. 05). BCVA and CMT changes between two groups were statistically significant differences (P<0. 05). One month and three months after the treatment:the BCVA increased while the CMT decreased compared with that of pretreatment in group A and B (P<0. 05), the difference was significant between two groups ( P< 0. 05 ). Six month after the treatment:the BCVA increased while the CMT decreased compared with that of pretreatment in groups A and B. Compare BCVA difference between the groups was statistically significant change (P<0. 05), CMT difference was not statistically significant (P>0. 05).?CONCLUSlON:Not only lVR can decrease ME caused by CRVO and increase the BCVA, but also lVR combined with PSTT can. But combined therapies can be more rapidly and have more positive effect on decreasing the ME and protecting the visual function.

OBJECTIVETo observe the effect of Modified Yiqi Chutan Recipe (MYCR) on blood flow perfusion in treating mid-late stage non-small cell lung cancer (NSCLC) patients by using multislice CT perfusion (CTP) , and to assess the relationship between each CTP parameter and the prognosis as well.

METHODSTotally 87 mid-late stage NSCLC patients were randomly assigned to the treatment group (44 cases, Shenyi Capsule + MYCR +chemotherapy) and the control group (43 cases, chemotherapy alone) in the ratio of 1:1. And 21 days consisted of 1 therapeutic course, 4 courses in total. All of them underwent CTP of primary tumor and routine thoracic CT examination (plain CT and enhancement CT) 3 times (before therapy, after 2 and 4 cycles). CT findings were analyzed for tumor size and perfusion parameters [blood flow (BF), blood volume (BV), permeability surface (PS), mean transit time (MTT), and time to peak (TP) before and after treatment, and relationship between perfusion parameters and prognosis was also assessed.

RESULTSIn 87 cases, 7 dropped out and 80 cases were available, 40 in the treatment group and 40 in the control group. (1) The relief rate was 47.5% (19/40) and the total stable rate was 77.5% (31/40) in the treatment group, and they were 40.0% (16/40) and 65.0% (26/40) in the control group, with no statistical difference between the two groups (χ² = 0.672, 1.227; P > 0.05). (2) Compared with before treatment group in the same group, BF and PS decreased, and MTT increased in the two groups after 2 and 4 courses (P < 0.05); BE and PS decreased, and MTT increased in the control group after 2 courses (P < 0.05). Compared with the control group after 4 courses, BE decreased more significantly in the treatment group (P < 0.05). (3) After 4 courses, all patients were assigned to the remission group (35 cases) and the non-remission group (45 cases) according to the RECIST standard. Compared with before treatment in the same group, BF, BF, and PS all decreased, and MTT increased in the remission group after treatment (all P < 0.05); BF increased in the non-remission group after treatment (P < 0.05). (4) All patients were assigned to the BE increase group (34 cases) and the BE decrease group (46 cases) according to changed BE values after treatment. Results showed the mean survival rate was 246 days in the BF increase group (the 1-year accumulative survival rate being 13.0%) and 387 days in the BE decrease group (the 1-year accumulative survival rate being 53.1%). The life span was prolonged and the 1-year accumulative survival rate was elevated in the BE increase group, with statistical difference as compared with the BE decrease group (χ² = 19.057, P < 0.01).

CONCLUSIONSShenyi Capsule plus MYCR could reduce BE in mid-late stage NSCLC patients , improve vascular permeability, showing better synergistic effect with chemotherapy. CTP could not only reflect the change of tumor size, but also reflect vascular function of the tumor. Meanwhile, changes of CTP parameters were closely associated with prognosis. Patients with post-treatment decreased BE value had better prognosis and longer life span.

The aim of this study was to detect the localization and level of tyrosine phosphorylated proteins during in vitro capacitation of guinea pig sperm. Sperm from mature guinea pigs were incubated in modified TALP under 5% CO_2 in air at 37 ℃. The capacitation effect was assessed by chlortetracycline (CTC) staining. Western blotting and indirect immunofluorescence were used to analyze the level and localization of tyrosine phosphorylation. The results showed that guinea pig sperm underwent a time-dependent increase in protein tyrosine phosphorylation during the in vitro capacitation and the percentage of protein tyrosine phosphorylated sperm increased from 36% to 92% from the beginning of incubation to 7h incubation. Also, there was a shift in the site of phosphotyrosine-specific fluorescence from the head of sperm to both the head and the flagellum of sperm. Moreover, there were three proteins phosphorylated in this experiment. After 0 to 0.5h incubation, the protein of 40kDa was detected by anti-phosphotyrosine monoclonal antibody, and the intensity of this protein increased in the following incubation. Then, after 1h incubation, another protein of 80kDa was found and the level of this protein reached the highest point at 3h. Also, in 3h incubation, a protein of 45kDa was detected and the intensity of this protein increased in the following incubation.

A 19-year-old Chinese woman presented with progressive ulcers and recurrent fever for 1 year.The lesions originally began with purplish red maculopapules,then rapidly developed into ulcer with severe pain and spread to the trunk and extremities accompanied by intermittent fever.Histopathology revealed lymphoid infiltration of middle and large atypical T cells throughout the dermis and subcutaneous fat laver along with focal epidermotropism.The lymphoid infiltrates were positive for CD3,CD8,T-cell intercellular antigen(TLA)and T-cell receptor β(TCR-β).Gene analysis showed the rearrangement of T-cell receptor gene.According to the above findings,the patient was diagnosed as primary cutaneous aggressive epidermotropic CD8-positive cytotoxic T-cell lymphoma. Combined thempy with cyclophosphamide,vincristine,prednisone and bleomycin resulted in partial remission of skin lesions,but she eventually died 22 months after the onset of disease.

Objective:To establish the HPLC fingerprint detection method for gynecological lotion. Methods:Wondasil C18 (250 mm × 4. 6 mm,5 μm)was selected as the analytical column. The mobile phase was composed of acetonitrile-0. 3% phosphric acid and 0. 3% diethylamine solution with gradient elution at a flow rate of 1. 0 ml·min-1 . The detection wavelength was set at 284 nm and the column temperature was 30℃. Ten batches of gynecological lotion were detected by the HPLC fingerprint and evaluated by Chromato-graphic Fingerprint Evaluation System of Chinese Medicine (2004 edition). Results: The separated peaks were clear and 15 common peaks were identified in the fingerprint of 10 batches of gynecological lotion. Conclusion: The HPLC fingerprint is with good repeat-ability and stability, which can provide evidence for the quality control of gynecological lotion.

[Objective]To evaluate the incidence of chromosomal abnormalities and associated abnormalities in prenatally diag?nosed clubfoot,and to determine the prognostic factors as well.[Methods]A total of 89 fetuses with clubfoot diagnosed during Janu?ary 2010 to October 2015 in prenatal ultrasound scan and confirmed postnatally or by autopsy,were selected,within which 16 (18.0%)cases were without other abnormalities and 73(82.0%)cases were with other abnormalities. The associated abnormalities were identified ,the correlation with chromosomal abnormalities were analyzed with Fisher analysis and the factors affecting the outcomes were determined with Logistic regression analysis.[Results]Among associated abnormalities ,the skeletal abnormalities besides the clubfoot were the most frequently associated anomalies (35 ,47.9%),and the central nervous abnormalities followed secondly(30,41.1%). A chromosomal abnormality,with trisomy 18 being the most frequently detected,was identified in 34%(17/49)of the clubfoot fetuses with other anomalies ,whereas none of chromosomal abnormality was identified in 11 fetuses without other anomalies,a significant different rate of aberrant chromosome noted(P < 0.001). The survival rate of clubfoot fetuses without other anomalies was higher than that of clubfoot fetuses with other anomalies(50.0%vs 1.3%,P=0.03). The conditions of with or without associated anomalies were the independent prognostic factors (P = 0.01),the clubfoot fetuses associated with other anomalies had poor outcomes[OR=11.9(95%CI:1.8,80.1)].[Conclusion]Skeletal abnormalities besides the clubfoot were the most frequently associated anomalies. The condition of with or without associated anomalies is the independent prognostic index for fetuses with clubfoot. Aneuploidy were more commonly in clubfoot fetuses with associated abnormalities than in those without other abnormalities. No indication for karyotyping suggests for the clubfoot fetuses without other abnormalities due to the low incidence of associate chromo?somal anomalies.
