?AlM: To discuss the differences in accommodative lag of different stimulation between the adolescent myopes who wore rigid gas permeable contact lens ( RGPCL ) and spectacles for one year.
?METHODS: Totally 85 myopes between 10-16y were enrolled in the study. Every subject was examined with the visual function test, medical optometry, corneal topography and ocular health check etc. of eyes. According to the above measurements and the compliance of children and their parents, 41 subjects were selected to wear RGPCL, 44 subjects were chosen to wear spectacles. Based on maximum plus to maximum visual acuity ( MPMVA) , accommodative lag was determined by dynamic retinoscopy method in two groups. The subjects were examined once every 3mo, accommodative lag was measured again using the same method for comparative analysis after one year. Wearing a year later, myopia progression of the two groups was measured and compared.
?RESULTS: There was no significant difference between two groups of initial accommodative lag (P>0. 05). After wearing one year, there was also no significant difference between the accommodative lag examined and the initial lag in RGPCL group (P>0. 05), the results demonstrate significant difference between the accommodative lag examined after wearing one year and the initial lag in spectacles group ( P < 0. 05 ). One year later, the differences were significant in accommodative lag between RGPCL and spectacles wearers stimulated by 2D, 3D and 4D ( P < 0. 05 ), and the accommodative lag increased with increasing stimulation in both groups. After wearing a year, the myopia progression of RGPCL group was less than spectacles wearers, and the differences were significant (P<0. 05).
?CONCLUSlON:After wearing RGPCL and spectacles one year in high accommodative stimulus, there is an obviously decreased in accommodative lag in RGPCL group, which suggests that RGPCL can control the progression of myopia in adolescents. The accommodative lag of the two groups increase obviously with increasing stimulation, which suggest that the adolescents need keeping good habits of reading.

Objective To investigate the imaging manifestations of metastasis in the nasal cavity and paranasal sinuses. Methods Twelve lesions of 10 patients with pathologically proved metastasis were retrospectively reviewed, including 6 renal clear cell carcinoma, 2 pulmonary adenocarcinoma, 1 colorectal carcinoma and 1 hepatic carcinoma. All the patients underwent CT and MRI scan.Among them,9 patients had contrast enhanced MRI scan and 5 patients had dynamic contrast-enhenced MRI as well. The location, bone changes, shape,margin,density,signal intensity, and enhancement characteristics of the lesions were observed. Results The metastasis involved spheno-ethmoid area(n=3), ethmoid sinus (n=2), maxillary sinus (n=2), nasal cavity(n=2), fronto-ethmoid area(n=2) and sphenoid sinus (n=1). All 12 metastatic lesions demonstrated bone destruction with tumor bone formation in 1 lesion. The CT displayed 10 metastases showed equal density, one mixed density was high, another form of low-density mixed. MR imaging showed equal signal in 9 lesions, while low-mixed signal in 3 lesions on T1WI compared with grey matter were found. On T2WI, 11 lesions showed high mixed signal and homogeneous low signal in 1 lesion. All 12 lesions demonstrated markedly heterogenous enhancement after intravenous administration of contrast media. Of 5 cases with dynamic contrast-enhanced MRI scanning, 4 lesions demonstrated wash-out time-signal intensity curve (TIC) pattern and 1 lesion demonstrated plateau pattern. Conclusions Renal carcinoma is the most common primary tumor for nasal cavity and paranasal sinuses metastasis. A typical imaging finding is located in the ethmoid sinuses, the soft tissue mass surrounded with rich blood supply multiple sinuses and significant bone destruction.

To explore the effect of Kudiezi injection on renal function in the real world, in order to provide the basis for the clinical medication safety. Patient aged between 18-80 were selected from 18 large hospitals information system (HIS) databases established by clinical research institute for basic traditional Chinese medicine of China academy of Chinese medical sciences. The patients who were treated with Kudiezi injection (24 225 cases) were defined as the exposed group, whereas those who were not treated with Kudiezi injection (14,191 cases) were defined as the non-exposed group. The propensity score method was used to balance the confounding factors. Classic logistic regression, GBM weighted propensity score logistic regression, GBM propensity score weighted logistic regression with covariate and sensitivity analysis were adopted to study the effect of Kudiezi injection on renal function. The results showed no significant difference in the possibility in abnormality in serum creatinine (Scr) (P = 0.940, 0.679, 0.834) and urea nitrogen (BUN) (P = 0, 0.045, 0.164) between both groups. Therefore, the existing data indicated no damage of Kudiezi injection on renal function. Because this study is a retrospective study based on the real world, there may be unknown confounding factors and potential bias. Therefore, further studies shall be conducted to monitor whether Kudiezi injection causes damage on renal function, in order to ensure the clinical medication safety.

OBJECTIVEThe present study was undertaken to design antisense oligodeoxynucleotides (AS-ODNs) of glial glutamate transporter-la (GLT-1a) and to evaluate the effectiveness of the designed AS-ODNs on the expression of GLT-1a.

METHODSFive sequences of GLT-1a AS-ODNs were designed according to the C terminus specific sequences of GLT-1a mRNA using antisense design software of IDT Com- pany. Western blot analysis was used to evaluate the inhibition effects of the five GLT-1a AS-ODNs on the expression of GLT-la.

RESULTSThe sequence of GLT-1a AS-ODNs with sequence of 5'-GGTTCTTCCTCAACACTGCA-3' could specifically inhibit the expression of GLT-1a in the hippocampal CA1 subfield of rats, while it had no effect on the expression of GLT-1b. This sequence showed similar inhibition on the expression of GLT-la in sham and ceftriaxone (Cef)-treated rats. It could also significantly inhibit the cerebral ischemic preconditioning (CIP)-induced up-regulation in the expression of GLT-1a. The magnitude of the inhibition in sham, Cef- or CIP-treated rats was similar by more than 60%.

CONCLUSIONFrom the designed five sequences of GLT-1a AS-ODNs, we obtained an effective sequence which can specifically inhibit the expression of GLT-1a.

This study aims to assess if adverse drug reactions (ADRs) to Kudiezi injection are allergic in origin. Hospital information system (HIS) data from 18 hospitals in China were used to carry out a nested case control design study. Included were patients who received dexamethasone for suspected allergic reactions after receiving Kudiezi injection. These were compared with non-allergic reaction people. Single factor logistic regression and multiple factor logistic regression were used to analyze data. Condition on admission, allergic history, dosage, disease status and drug combinations were taken into account in cases of suspected allergic reactions. After analysis in two subgroups we found that the condition on solvents had a significant effect, P values were 0.005 5 and < 0.000 1 on suspected cases of allergic reactions. For the first subgroup analysis, we found using other eight injections at the same time as Kudiezi injection could be risk factors in suspected cases of allergic reactions. For the second subgroup analysis combining using mannitol or fructose could increase risks. Based on this current research, condition on admission as well as the concomitant use of some other drugs may be the risk factors in suspected cases of allergic reactions. However, further research for verification is required. This study can provide guidance for safe clinical practice in using Kudiezi injection.
