AIM: To report a case of late onset diffuse lamellar keratitis (DLK) after laser in situ keratomileusis(LASIK) in 11 months due to corneal trauma. ·METHODS: A 22-year-old female patient underwent uneventful bilateral LASIK using a laserSight SLX excimer laser and Moria II microkeratome. No complications were observed during the operation and the early postoperative period.·RESULTS: 11 months after LASIK, grade I DLK was diagnosed after the book paper hurt the right corneal epithelium. The DLK responded rapidly to topical corticosteroid therapy, and healed in 2 weeks without complication. ·CONCLUSION: Although DLK Wpically develops in the early postoperative period, it could occur months after surgery. Treatment should begin as soon as DLK is diagnosed.

Objective: To observe the effect of flavonoid from Glycyrrhizae Radix (FGR) on the migration of small intestinal epithelial cells (IEC-6) and intracellular polyamines content. Methods: The cell migration model was constructed by scratch method. Under the intervention of α-difluoromethylornithine (DFMO), the specific inhibitor of polyamine synthesis, or 4-aminopyridine (4-AP), the specific inhibitor of potassium channel, the effect of FGR on cell migration was observed. The intracellular polyamine content being cultured for 12 or 24 h in normal and DFMO intervention condition was detected by precolumn derivatization-HPLC. Results: FGR could reverse the inhibitory effects of DFMO and 4-AP on cell migration, increase the intracellular content of polyamines after 12 or 24 h treatment, and reserve the decrease of polyamine content caused by DFMO. Conclusion: FGR could affect the polyamine-dependent signaling pathway, which may be related to the mechanisms for FGR promoting cell migration.

ObjectiveTo study changes of bone measured with quantitative ultrasound (QUS) in women of Guangzhou area and provide scientific basis for prevention and treatment of osteoporosis (OP).MethodsCalcaneus measurement was done with QUS in 647 women of Guangzhou area, and measurement data was analyzed.ResultsIn menopause and aged women, broadband ultrasound attenuation (BUA) showed a significantly decrease (P<0.01), whereas it decreased only slightly in early postmenopausal women (P>0.05). After the peak of BMD, speed of sound (SOS) showed a stepwise decline, and significantly decrease in menopause (P<0.01), but not significant over eighties (P>0.05). In contrast, stiffness index (STI) significantly decreased from the menopause, and it was a better indicator than BUA or SOS.ConclusionQUS can not only test bone mass but also assess microarchitecture, and it is nonradioactive, cheaper, easier to use, and may play a important role in diagnosis of osteoporosis and women and senile health.

Objective To investigate the profit-loss of the hospital's DRGs pilot and its reasons.Methods An investigation of the profit-loss situation of 9 225 cases of a hospital in Beijing,who have been discharged from December 2011 to December 2013 and grouped into 105 DRG pilot groups.Results As shown in the medical records of 9 225 cases,96.54％ are covered by urban employee basic medical insurance,and 3.46％ by urban residents' medical insurance; 78 DRGs groups were recorded as with profit(74.29 ％),while 27 recorded as with a loss(25.71％) ;average length of stay as 9.37 days,average expense per hospitalization per person as 18 032.27 yuan,average quota standard as 17 337.53 yuan,average out-of-pocket cost as 829.47 yuan,average second charge as 2 448.57 yuan,average profit as 2 583.29 yuan,average sum of out-of-pocket payment ratio and second charge ratio as 12.46％.Conclusion The current DRGs pilot model shows the hospital as profit making in general,with no significant impact on the hospital.

BACKGROUND: Repeated blood transfusion and recombinant human erythropoietin (rhEpo) have been previously used to improve anemia following chronic renal failure; however, their clinical applications are extremely limited by various side effects. OBJECTIVE: To investigate the therapeutic effect of allograft renal transplantation with rhEpo on anemia following chronic renal failure via verieying quality and quantity of some examines. DESIGN, TIME AND SETTING: A randomized grouping animal study was performed in Laboratory of Physiology. Shanxi Medical University from June 2004 to March 2005.MATERIALS: Eighty healthy adult male Wistar rats collected as receptors were injected with doxorubicin hydrochloride (6.5 mg/kg)into caudal vein three times per week for six weeks in total. Right kidney was then exsected to establish model of chronic renal failure. Another 20 newborn Wistar rats (3-4 days old, of both Sexes) were selected as donor. RhEpo (2000 U/mL) was provided by Shangdong Ahua Pharmaceutical Company (batch number-99435). METHODS: 20 adult rats in the control group did not undergo any treatments, and then other 60 adult rats were randomly divided into three groups of 20 rats per group after chronic renal failure modeling. Adult rats in the transplantation group underwent multidrop wansplantation of renal tissue into renal envelop; adult rats in the rhEpo group were intraperitoneally injected with rhEpo (30U/kg) three times Der week for six successive weeks in total; adult rats in the model group did not undergo any treatrnents. MAIN OUTCOME MEASURES: SABC assay was used to detect expression and distribution of rhEpo in reDal tissue and graft. ELISA was used to directly measure level of serum rhEpo in angular vein, routine assay was used to measure level of hemoglobin, and the corresponding kits were used to measure content of Na+-K+ATPaSe. activity of superoxide dismutase (SOD).and level of malondialdehyde (MDA)in erythrocyte membrane. RESULTS: rhEpo-antigen positive reaction showed a strongly positive expression in the control group. a weakly positive or an absent expression in the model group, and a strongly positive expression in the transplantation group. There were significant differences in the model group as compared to other two groups(P＜0.01).After 30,45,and 60 days, rhEpo level and numbers of hemoglobin and erythrocytes were higher in the rhEpo group and transplantation group than those in the model group(P＜0.05-0.01).After 60 days,rhEpo level in the rhEpo group was higher than that in the transplantation group (P＜0.05).On the other hand,after 30,45,and 60 days,MDA content in the rhEpo group and transplantation group was lower than that in the model group(P＜0.05).but there were no significant difeerences between rhEpo group and transplantation group(P＞0.05).Changes of SOD and Na+-K+ATPase were opposite to MDA among these groups.CONCLUSION:Renal transplantation can increase quality and quantity of erythrocytes of rats with anemia caused by chronic renal failure.The eflfect is equivalent to rhEpo.

Objective To investigate the efficacy and safety of using adsorption method combined with warm saline in heparin- free dialysis for patients with high risk bleeding tendency in order to reduce blood ag-glutination in the dialyzer and pipeline. Methods 60 patients with high risk bleeding tendency who were to undergo long- term hemodialysis (HD) were divided into the experimental group and the control group with 30 eases in each group,they both adopted heparin- free dialysis.The control group used saline washing of room temperature, while the experimental group adopted adsorption method combined with warm saline during washing. The completion of dialysis as well as the agglutination in the dialyzer and pipeline were ob-served. Results Number of patients who completed the dialysis were more, the completion rate of dialysis was higher and agglutination of dialyzer and pipeline decreased in the experimental group than those in the control group. Conclusions Agglutination of dialyzer and pipeline can be reduced and the aim of safe and effective heparin- free dialysis can be reached when using adsorption method combined with warm saline.

The pharmaceutical properties, including the physical and chemical properties, and the bioavailability are greatly influenced by their polymorphism. In this paper the polymer heteronuclei were used to produce the gabapentin polymorphs that were characterized by X-ray powder diffraction, FT-IR and DSC. The results indicated that the polymer heteronuclei are an effective method to control and select the gabapentin polymorphism. One new polymorph of gabapentin was found besides all known gabapentin polymorphs.
