Bilateral sequential cataract surgery is very common in clinical,but the ophthalmologists often ignore how to choose the timing of operation and whether the first eye can be used to improve the intraocular lens (IOL) power calculation for the second one.Despite the refinements in IOL selection with the use of third-generation IOL formulas,5％ of eyes still result in a postoperative refractive surprise of ± 1.00 D or more.This paper introduced the methods of using refraction error of the first eye to improve the IOL power calculation for the second eye,and the refractive error of the second eye can be improved by modifying the IOL power to correct up to 50％ of the error from the first eye in details.Because of the variation of the postoperative refractive surprise within a month,the interval of three to four weeks between two eyes cataract surgery is highly recommended.These conclusions may provide the advantageous guidance for us in the selection of IOL in bilateral cataract surgery.

OBJECTIVE: To characterize the pharmacokinetics of a single dose of 2.5 mg fondaparinux sodium in Chinese patients after thoracic surgery. METHODS: Thirteen patients were enrolled in the study and were given a single dose of 2.5 mg fondaparinux sodium via a subcutaneous injection. Plasma concentrations of fondaparinux sodium were measured throughout a 24 h period. The pharmacokinetic analysis was performed using WinNonlin software. RESULTS: The following pharmacokinetic parameters were derived; t1/2(7.92 ± 3.13) (4.21-15.89) h, tmax(2.52 ± 0.93) (1.38-4) h, p-1 (0.73 ± 0.18) (0.45-1.02) mg · L-1, AUClast(6. 56 ± 2.19) (3.07-9. 75)mg · h · L-1, Vz/F(3.54 ± 1.00) (2.24-5.73) L, CL/F(0.34 ± 0.14) (0.16-0.63) L · h-1, and MRTlast (6.98 ± 2.1) h. The pearson correlation coefficient, r was 0.7283(P = 0.005) between the serum creatinine(Scr) and mean residence time(MRTlast) of fondaparinux. CONCLUSION: The disposition of fondaparinux is highly variable in patients. A statistical significant correlation between Scr and MRTlast of fondaparinux was observed. Fondaparinux sodium administered by intravenous injection is well tolerated in patients.

MicroRNA is a type of endogenous noncoding small molecular RNA with a length of 19-25 nucleotides. MicroRNAs are involved in almost all key biological processes, such as cell proliferation, differentiation, apoptosis, and hematopoiesis, via repres-sion of target gene expression. Acute lymphoblastic leukemia (ALL) is the most common type of pediatric cancer. It is a heterogeneous disease with different clinical signs, morphology, immunophenotype, and cytogenetics. Currently, several microRNAs have implicated aberrant expression in ALL and play an important role in cancer initiation and development. MicroRNA expression pattern is associated with clinical feature, prognosis, and treatment. Therefore, microRNAs could act as a novel marker to help scientists learn about the pathogenesis of ALL and to provide more effective treatment options.

Chloasma is a kind of skin disease with pigmentation on the face, which can be frequently seen in child-bearing age women. The disease is caused by Zangfu dysfunction, Qi and blood deficiency. For women, the generation of chloasma is closely related to their menstruation. Regulating the menstrual function with traditional Chinese medicine and balancing the body's internal environment can be very useful for achieving the balance between Yin and Yang within Zangfu, and regulating Qi and blood, which will not only desalt pigment, but also can improve the symptom related to menstruation with low recurrence rate after drug withdrawal. This method can be used alone or with other methods in clinic, has achieved significant effect.

Objective To investigate the correlation between the inflammatory-nutritional index (INI) and recurrence and prognosis in patients with gastric cancer. Methods A total of 78 cases patients of gastric cancer with recurrence and 64 cases without recurrence were enrolled. INI was calculated by the ratio of serum albumin and C-reactive protein. The value of INI predicting recurrence was analyzed using receiver operating characteristic curve (ROC). According to this value, the Kaplan-Meier curves and Cox regression analysis were used to evaluate the effect of INI on prognosis. Results Compared with the control group, the recurrence group showed smaller INI, larger tumors, lower degree of differentiation, deeper invasion and higher TNM stage, the differences were statistically significant (all P < 0.01); The INI significantly predicted the recurrence of gastric cancer, with a sensitivity of 62.5%, specificity of 79.5% and critical value of 0.36 (P < 0.01); Additionally, The pathological features were worse in the low INI group than the high INI group , the differences were statistically significant (P < 0.01); The INI significantly predicted the prognosis of gastric cancer, with a sensitivity of 65.9%, specificity of 66.8% and the critical value of 0.34 (P < 0.01); Obviously, the survival rate was lower in the low INI group than the high INI group (48.8% vs 25.0%, P < 0.01). Furthermore, INI was an independent risk factor for prognosis of gastric cancer (OR = 1.78, 95% CI: 1.34 ~ 2.59, P < 0.01). Conclusion The INI is closely related to the characteristics of gastric cancer, it is an effective marker to predict recurrence and prognosis of gastric cancer.

Inflammatory bowel disease( IBD)is a chronic and nonspecific intestinal inflammatory disease caused by multiple factors such as environment,genetic susceptibility and immune disturbance. Autophagy plays an important role in cellular homeostasis and immune. Autophagy abnormalities may be involved in the pathogenesis of IBD. Genome-wide association studies(GWAS)have provided compelling evidence that autophagy related genes,including ATG16L1,IRGM and NOD2,are significantly associated with IBD. This article reviewed the abnormal autophagy in pathogenesis of IBD.

The aim of the study was to optimize the coating formulation of sustained release pellets of loxoprofen sodium by the central composite design-response surface methodology(RSM plus CCD).In the formulation design using RSM plus CCD,independent variables were the ratio of HPMC to EC(X_1) in the sustained coating formulation and polymer load(weight gain,X_2) were selected as in dependent variables,and in vitro accumulated releases from the pellets at 1,4,and 8 h were dependent variables.Multilinear,two and three order quadratic models were used to estimate the relationship between the dependent and the independent variables,and to delineate RSM and overlay contour plots in order to select the optimal formulations in compliance to the hypothesized in vitro releases (%) at 1,4,and 8 h.The results showed that the relationship between dependent and independent variables was best fitted to three-order quadratic equation.The regression equation generated for the hypothesized in vitro cumulative releases(%) at 1,4,and 8 h were Q_(1h) =227.699 2-30.785 9X_1-43.395 4X_2 + 0.917 4X_1~2 +1.820 3X_2~2 +6.803 9X_1X_2-0.131 5X_1~2X_2-0.268 2X_1X_2~2,Q_(4h) =408.254 0-47.427 8X_1-75.229 2X_2 +3.304 0X_2~2 +12.357 3X_1X_2-0.111 8X_1~2X_2-0.5425X_1X_2~2,Q_(8h) =303.539 0-30.417 6X_1-45.114 0X_2 +2.064 4X_2~2 +6.865 0X_1X_2-0.3341X_1X_2~2,respectively.In the optimized coating formulation,the ratio of HPMC to EC was 4.0% and the polymer load 9.0%.Bias between observed and predicted values in vitro accumulated releases were negligible,indicating the high predictability of the selected models.Therefore,RSM plus CCD is applicable in the optimization of the coating formulation of loxoprofen sodium sustained-release pellets.

Objective To study the effect of different draining way in the surgical treatment of chronic subdural haematoma (CSDH). Methods 126 patients with CSDH diagnosed by CT scanning or MRI were enrolled. The burr-hole was made at the site of the maximal hematoma thickness. A drainage tube was placed towards either the occipital (group A) or frontal ( group B) region as far as possible respectively, and for the latter, a lateral aperture was made about 2 cm far from the burr-hole on the side of the tube. The surgical complication (such as pneumocephalus, brain injury and recurrent hematoma et al.) and therapeutic efficacy of the two treatments were compared and analyzed to evaluate an optimal surgical technique. Results After treatment, complication rate in group A is 30%, the occurrence of complications in group B rate is 2% (P <0.05); operation time and hospitalization time in group B was significantly shorter than that in group A (P <0.05). Conclusion In the surgical treatment of CSDH, improved drainage pathway is safe and effective, which could improve the treatment efficacy and is worthy of clinical promotion.
