OBJECTIVE To discuss the factors and control steps of hospital infection in ophthalmology and to reduce it.METHODS To aim at the cause of hospital infection in ophthalmology,corresponding management countermeasures were taken.RESULTS The hospital infection in ophthalmology was avoided by strengthening knowledge training to increase full cognition;establishing sanity bylaw;strengthening cleanliness and antisepsis of environment,preventing air pollution;strengthening the management of operating room and patient;and insuring the application of unified method,which including cleaning,antisepsis,and sterilization quality for diagnostic and therapeutic devices.CONCLUSIONS Hospital infection in ophthalmology could be effectively prevented by establishing and carrying out seriously the bylaw and measure adapting to the ophthalmology specialty and the control of the hospital infection.

Objective:To investigate the effect of the ERK1/2 signal-transduction pathway on differentiation of rat mesencephalic neural stem cells(NSCs)in presence of bone marrow stromal cell-conditioned medium(BMSCs-CM)in vitro.Methods:NSCs were cultured on poly-L-lysine(PLL)coated 35 mm dishes.The neurospheres adhered to the bottom 30 min later;then the culture medium of natural differentiation group was replaced by neurobasal medium containing 2% B27;the control group was replaced with BMSCs- CM;and the inhibition group was replaced with BMSCs-CM containing PD98059(5?mol/L).The proportions of neurons and astrocytes and their morphological difference were observed by immunocytochemistry technique 7 d later.Results:We successfully cultured NSCs from adult rat BMSCs-CM.The proportion of neurons in the natural differentiation group(15.70?10.3)% was lower than that in the control group([51.17?10.30]%,P

Objective To investigate the causes of the postoperative complications from partial splenic cmbolization (PSE) and make the nursing measures.Methods 18 patients with secondary hypersplenism due to posthepatitic cirrhosis and portal hypertension,5F RH type or Cobra catheter was placed selectively into splenic artery through femoral artery by DSA fluoroscopy.60～120 masses of 1 mm×1 mm×1 mm gelfoam mixed with antibiotic and conmist medium were injected fractionally.The routine blood test,hepatic function,serum amylase,urinary amylase,Bmode ultrasonic or CT scan on spleen were tested regularly in week 1,week 2,week 3,week 4 and half-year after PSE.Results The Postoperative Complicatiorm iuchded fever,abdom inal pain,pleural effusion,ascites pertinacions hiccup,splenic abscess impairment of liver and renal function,portal thrombosis left-lower pneumonia and so on.Conclusion Mastering the causes of the complications related to PSE and giving accurate nursing in time may decrease or avoid the incidence of complications and increase the succeas ratio of operation.

In order to further the progress of the quality of adult medical education,several factors need to be considered.We should take into account individualized teaching in accordance to the different knowledge base.We should also consider the different learning abilities of adult students by analyzing their features in medical colleges setting.

Episodic tension-type headache is the most common headache in the general population and is usually self managed.Chronic tension-type headache may be highly disabling and often prompts medical consultation.Diagnosis is clinical,based on widely accepted and validated criteria and algorithm.Peripheral factors are implicated in episodic tension-type headache,whereas central factors probably underlie chronic tension-type headache.Simple analgesics,such as aspirin,are used for acute treatment.Amitriptyline and biofeedback assisted relaxation training have the best evidence of effectiveness for headache prevention.

OBJECTIVE To find standard for the management of the medical waste through the plan,do,check and action(PDCA) loop method. METHODS Four steps of PDCA were done to treat the medical wastes. RESULTS Establishment of the effective management of organization and the feasible rules and regulations was an important pledge.Training,propaganda and education for enhancing every-one′s management consciousness were a considerable element.Matching institutions for treating medical waste was the most important basis.Examinations according to the formulated quality specification were the artifice. CONCLUSIONS PDCA loop method is one of the scientific management for treating the medical wastes.

Objective:To observe the clinical efficacy and safety of traditional Chinese medicine Xiaozuo decoction combined with 0. 025% vitamin A for external use in the treatment of acne vulgaris. Methods:Totally 86 patients with acne vulgaris were randomly di-vided into the treatment group and the control group with 43 ones in each. The treatment group was treated with Xiaocuo dcoction, 1 dose/day, and the control group was orally treated with erythromycin ethylsuccinate, 0. 25g per time, 3 times per day. The treatment course was 6 weeks, and both groups were treated with 0. 025% tretinoin cream once every night. The clinical efficacy and adverse drug reactions were compared between the two groups. Results:The obvious effective rate of the treatment group and the control group was 69. 77% and 41. 86%, respectively, and the total effective rate was 88. 37% and 69. 77%, respectively. There was significant difference in the obvious effective rate between the two groups (P<0. 01), while there was significant difference in the total effective rate between the two groups (P<0. 05). Recurrence rates of two groups were 10. 00%and 22. 22%,respectively,and there was no sig-nificant difference (P>0. 05). There were no serious adverse reactions in the two groups. Conclusion: Xiaocuo decoction combined with 0. 025% tretinoin in the treatment of acne vulgaris has promising clinical efficacy with high safety.

Objective To investigate and analyze the prevalence of metabolic syndrome and its components among staffs of Guangdong. Methods One thousand six hundred and fifteen persons were enrolled in this survey. The medical check up data from the physical examination were analyzed. Results The prevalence of metabolic syndrome, obesity, hyper-triglyceridemia, hypo-HDL-C, hypertension, glucose metabolic disorder were 16.3% ,27.6% ,22.7%, 15.0% ,51.8%, 10.7% respectively. The MS prevalence was increased with aging. Prevalences of 0-5 MS components were 31.5% ,31.2% , 22.2% , 10.0% ,4.7%,0.3% respectively. It was significant difference between 2 groups that UA, ALT, AST, CHOL, LDL-ch (t value is 6. 473,4. 238,7. 406,6.810,8. 350, seperatly, P<0.01). Conclusions The prevalence of MS is high in the staffs of Guangdong. The blood pressure increasing prevalence was maximal. The other components prevalences were high too. MS tends to be a many data abnormality disease, early detection and intervention are important.
