Objective To compare the clinical and MRI characteristics of pituitary macroadenoma between male and female patients. Methods Two hundred and thirty patients with pathologically diagnosed pituitary macroadenomas (104 mlaes and 126 females) were divided into two groups according to different gender. Patient age, the ratio of intratumoral hemorrhage and cavernous sinus invasion, and tumor volume were calculated in each group and compared between the two groups. The constitution of different pathological types was also compared. Results The age, ratio of intratumoral hemorrhage and cavernous sinus invasion, and tumor volume was (44.8±13.2) years old, 21.15% (22/104), 50.00% (52/104), and 6100.48 (mm3, median) in the male group and (44.8±11.9) years old, 28.57% (36/126), 48.41% (61/126) and 5037.05 (mm3, median) in the female group, respectiveluy. There was no statistical difference between the two groups regarding to patient age, the ratio of intratumoral hemorrhage and cavernous sinus invasion, tumor volume, and constitution of pathological types (P=0.972, P=0.197, P=0.811, P=0.189, P=0.093, respectively). Conclusion Pituitary macroadenomas show no gender preference in clinical and MRI characteristics.

Aim To observe the effect of 5-FU and L-Arg on the human liver carcinoma model in nude mice and study the mechanism.Methods We established the human liver carcinoma model in nude mice with BEL-7402 cell and gave normal saline,5-FU,5-FU+L-Arg by intraperitoneal injection. The tumor size was measured.The necrotic degree and range were observed by the microscope. Immunohistochemistry method and chemical colorimetry were performed to determine the expression and activity of iNOS. Nitrate reductase method was adopted to test the concentration of NO in the tumor tissue. The one-way ANOVA,Bonferroni and Kruskal-Wallis H tests were adopted for the statistical analysis.Results 5-FU combined with L-Arg promoted the tumor suppressive action apparently. The necrotic range enlarged. The expression and activity of iNOS increased. The production of NO also increased.Conclusions 5-FU combined with L-Arg has agonist effects on the inhibition of the growth of human liver carcinoma in nude mice.It may be related with inducing the synthesis of iNOS and the increase of NO.

Objective To investigate the clinical therapeutic effect of Shenqi Fuzheng injection for treatment of patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD).Methods A prospective clinical study was conducted. Fifty-eight consecutive patients with AECOPD were admitted in Departments of Respiratory Disease and Critical Care Medicine in Zhuozhou City Hospital of Hebei Province from January 2012 to December 2013. They were randomly divided into western medicine (WM) control group (28 cases, the routine treatment of WM) and integrated traditional Chinese medicine (TCM) with WM group (30 cases, on the basis of conventional therapy, Shenqi Fuzheng injection 250 mL intravenous drip was given once a day for a therapeutic course of 10 days). The duration of mechanical ventilation, the successful rate of weaning from ventilator, the rate of using ventilator again after weaning, the length of stay in intensive care unit (ICU), and mortality were recorded respectively in the two groups. Before and after treatment, the arterial blood gas analysis, acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, clinical pulmonary infection score (CPIS), pulmonary function and dyspnea score were evaluated. Results Compared with the WM control group, the duration of mechanical ventilation (hours: 104±16 vs. 125±24) and the length of stay in ICU (days: 6.3±2.1 vs. 7.2±3.6) were significantly shorter, the rate of successful weaning from ventilator was obviously higher [73.3% (22/30) vs. 60.7% (17/28)], and the rate of using ventilator again after weaning was remarkably lower [13.3% (4/30) vs. 28.6% (8/28)] in the combined TCM and WM group, the differences between the two groups being statistically significant (allP < 0.05); the mortality was lower in the combined group [10.0% (3/30) vs. 10.7% (3/28)], but there was no statistically significant difference (P > 0.05). Compared with those before treatment, the pH value, arterial partial pressure of oxygen (PaO2), forced expiratory volume in 1 second (FEV1), forced vital capacity(FVC) and the ratio of FEV1/FVC were all significantly higher in the two groups after treatment, while the partial pressure of arterial carbon dioxide (PaCO2), APACHE Ⅱ score, CPIS score, residual volume/total lung capacity (RV/TLC), and the dyspnea score were all lower in the two groups after treatment, the more obvious changes in levels being after 10 days of treatment in combined TCM and WM group [pH: 7.44±0.04 vs. 7.40±0.08, PaCO2 (mmHg, 1 mmHg = 0.133 kPa): 59.1±11.9 vs. 68.1±12.4, PaO2 (mmHg): 70.5±6.9 vs. 65.1±7.4, APACHE Ⅱ score: 14.5±4.2 vs. 17.4±2.2, CPIS score: 5.3±2.4 vs. 7.6±1.4, FEV1 (L): 1.60±0.47 vs. 1.54±0.34, FEV1/FVC: (65.33±2.65)% vs. (62.00±3.25)%, FVC (L): 1.72±0.21 vs. 1.66±0.21, RV/TLC: (42.13±1.67)% vs. (43.12±0.95)%, dyspnea scores: 1.71±0.54 vs. 2.32±0.65, allP < 0.05].Conclusion Shenqi Fuzheng injection possesses certain clinical value in treatment of patients with AECOPD, as it can obviously improve the pulmonary function and the data of arterial blood gas analyses, and effectively relieve the clinical symptoms.

Objective To explore the types, degree and distribution regularities of axial direction in astigmatism preschool children and the relationship of astigmatism and amblyopia. Methods Mydriasis optometry was performed for preschool children in our hospital outpatient reception from 2010 to 2011,and the astigmatism in 831 eyes of 477 cases were statistically analyzed. Results The compound hyperopic astigmatism was the most, accounting for 65.8%,followed by mixed astigmatism (13.8%),simple hyperopia astigmatism (9%),compound myopia astigmatism (8.7%) and simple myopia astigmatism (2.3%). Preschool children astigmatism degree distribution was distributed among 0.50 D and 2.00 D, accounting for 42%. For astigmatism axial, the astigmatism with rule, astigmatism against the rule and oblique astigmatism was accounted for 95.9%, 2.4% and 1.7%, respectively. Conclusion Compound hyperopic astigmatism is a main type of astigmatism in preschool children, and astigmatism is closely related to the formation of amblyopia.
