AIM:To explore and compare effect of coaxial micro-incision phacoemulsification and standard coaxial phacoemulsification in the treatment of cataract.
METHODS:A total of 88 patients(88 eyes) with senile cataract who underwent selective cataract ultrasonic emulsification resorption combined with intraocular lens implantation in the hospital from Aug. 2013 and Aug. 2015 were selected, they were divided randomly into the control group ( 44 cases, 38 cases completed, 6 cases dropped out ) and the observation group ( 44 cases, 40 cases completed, 4 cases dropped out ) . The control group received standard coaxial 3. 0mm small incision phacoemulsification, the observation group received coaxial 1. 8mm micro-incision phacoemulsification. All patients were combined with intraocular lens implantation. Intraoperative effective ultrasonic time, cumulative release energy, best corrected visual acuity before and after surgery in the two groups were recorded, corneal endothelium cell population, incision corneal thickness, percentage of cornea hexagon cell, corneal astigmatism changes before the operation, 1d, 7d, 30d after the operation were compared.
RESULTS: There was no significant difference in intraoperative effective ultrasonic time, cumulative release energy in the two groups(P>0. 05). There was no significant difference in postoperative best corrected visual acuity between the two groups(P>0. 05). Corneal endothelium cell population, percentage of cornea hexagon cell 1d, 7d, 30d after the operation in the two groups were significantly decreased compared with those before the treatment ( P < 0. 05 ), but there was no significant difference in the two groups ( P > 0. 05 ). Incision corneal thickness 30d after the operation in the observation group was significantly lower than the control group(P<0. 05). Degree of corneal astigmatism in the observation group 1d, 7d, and 30d after the operation were significantly lower than the control group (P<0. 05).
CONCLUSION: Coaxial micro - incision phacoemulsification and standard coaxial phacoemulsification can improve visual acuity of cataract patients, but the former can reduce degree of corneal astigmatism.

Objective To investigate the efficacy of losartan combined with amiodarone in cardioversion of atrial fibrillation(AF)and maint of sinus rhythm in patients with paroxysmal AF.Methods From January 2003 to October 2005,a total of 86 consecutive patients with paroxysmal AF in 421 Hospital of PLA were randomly dividid into two group:group A(amiodarone,n=44)and.group B(amiodarone plus losartan n=42).The conversion of atrial fibrillation in 24 h,3 d and 7 d after therapy was investigated.The left atrial diameter was measured with transthoracic echocardiogram at before and after 6,12-months of treatment andyzed up to 12 months.Results The rate of cardioversion of AF is significantly higher in group A than group B at 7 d(86.36% vs 95.23%,P

BACKGROUND:The rabbits were widely used as experimental animal models in the research on etiology and pathological mechanism of steroid-induced osteonecrosis of the femoral head. It is stil a valuable and realistic research topic to improve and to innovate the modeling technology nowadays. OBJECTIVE:To improve the modeling technology on osteonecrosis of the femoral head in rabbits induced by glucocorticoid combined with lipopolysaccharide, with the focus on its reduced mortality and the guaranteed successful rate of modeling. METHODS:A total of 28 New Zealand white rabbits were randomly divided into the control group (n=10) and improvement group (n=18). Models of steroid-induced osteonecrosis of the femoral head were established according to different methods. In the improvement group, rabbits were injected with sodium penicilin (5.0 mg/kg) and amikacin sulfate (1.63×104 U/kg) in the left gluteus muscle. Twenty-four hours later, al rabbits were injected with prednisolone acetate (20 mg/kg) in the right gluteus muscle. Forty-eighthours later, 5.0 μg/kg of lipopolysaccharide was intravenously injectedvia the ear. From then on, two injections of prednisolone acetate (20 mg/kg) were respectively performed alternately in the left and right gluteal muscle at an interval of each 24 hours. Sodium penicilin (5.0 mg/kg) and amikacin sulfate (1.63×104 U/kg) were intraperitonealy injected for 2 consecutiveweeks. In the control group, 10 μg/kg lipopolysaccharide was injectedvia the ear vein of rabbit. From then on, prednisolone acetate (20 mg/kg) was intramuscularly injected at an interval of each 24 hours, totaly three times. Benzylpenicilin sodium 20×104 U/rabbit was intramuscularly injected once a week. RESULTS AND CONCLUSION:Rabbit models of steroid-induced osteonecrosis of the femoral head were successfuly established in both groups. Compared with the control group, the mortality was significantly reduced after model establishment in the improvement group, and the bone lacuna and osteonecrosis of the femoral head were apparent. These findings indicated that the improved technology of model establishment of steroid-induced osteonecrosis of the femoral head could be used to aleviate the damage degree on the gluteal muscles, to guarantee the successful rate of modeling, and to noticeably reduce the mortality of rabbits.

OBJECTIVE: To obtain data related to clinical pharmacy services of Tertiary hospitals, find problems in the service system, based on which provide advice on policy formulation. METHODS: A face-to-face interview survey was conducted to collect data on management system construction, hardware & facility equipment and professional staffing, et al which was analyzed with descriptive statistics tools. RESULTS: Only 59.7% of the hospital within the sample established clinical pharmacist performance appraisal systems; 18.4% of the hospital's clinical pharmacy services were charged; 30.0% of the hospitals provided offices for clinical pharmacists; each 100 beds were equipped with an average of 5.6 technical professionals and an average 0.43 clinical pharmacists; most of the professionals' educational background were undergraduate (51.5%) and below undergraduate (28.7%), and most of the professionals' professional titles were primary (53.1%) and intermediate (33.4%); dispensing remained main duty of pharmaceutical professionals(67.4%).CONCLUSION: Management system construction, hardware & facility equipment and professional staffing of tertiary hospitals in China require further improvement.

Pulmonary fibrosis is a common pathological change in many chronic lung diseases, and its pathogenesis and characteristics are mainly caused by repeated lung alveolar injury leading to abnormal activation of fibroblasts and the accumulation of large amounts of extracellular matrix (ECM) deposition. Fibroblasts are not only responsible for constituting the interstitial structure of the lung but are also involved in the post-injury repairment in healthy lung tissue. In contrast, fibroblasts show a typical pro-fibrotic metabolic phenotype after differentiation into myofibroblasts during the development of pulmonary fibrosis. To synthesis large amount of collagen, the myofibroblasts have a strong metabolism characteristic of serine/glycine, glutamine, proline, and arginine. At the same time, the myofibroblast get the ability to resist cell apoptosis. As an important cell type for collagen degradation, fibroblasts reuse the amino acids of collagen to maintain cell metabolism. However, the myofibroblasts cannot degrade the ECM due to the suppression of autophagy activity, thus accelerating the progression of pulmonary fibrosis. This review attempts to summarize how amino acid metabolism of fibroblasts influence the pulmonary fibrosis.
