Diabetic retinopathy (DR),one of the most serious microvascular complications of diabetes mellitus,leads to the increasing blindness rate,which seriously affects the quality of life in diabetic patients.Although the actual mechanism of DR is not yet completely clear,mounting evidence suggests that the development of DR may be associated with inflammatory processes and inflammatory factors,such as C-reactive protein (CRP),chemotatic factor,adhesion molecule,interleukin,tumor necrosis factor-α (TNF-α),serum amyloid A (SAA).Usage of glucocorticoids,non-steroidal anti-inflammatory drugs(NSAIDs),minocycline and anti-inflammatory factors to inhibit inflammatory process would be a new approach to the treatment of DR.This article reviews the current studies about the effects of inflammatory reaction and inflammatory factor in the pathogenesis of DR,mechanism of suppressing inflammatory response and anti-inflammatory factor in the treatment of DR.

Objective: To observe the histomorphology/pathology changes and the expression of hypoxia inducible factor-1 alpha (HIF-1α) and vascular endothelial growth factor (VEGF) in drowning rats brain, in an attempt to explore new pathways for treatment of water drowning. Methods: The animal model of freshwater drowning was established with rats. The rats were randomly divided into the following groups: control group, drowning-to- death group and 2 min-drowning group (including 5 subgroups survived for 3, 6, 12, 24, and 40 hours after being drowned in water for 2 min [n=10]). Brain indices of rats in each group were detected and the pathological changes of cerebral tissues were observed; the expression of HIF-1α and VEGF were detected immunohistochemically and the correlation between them was analyzed. The dynamic blood oxygen saturation was detected in rats survived for 40 h after 2 min-drowning at different points. Results: Brain index of the drowning group and groups surviving for 24, 40 hours after drowning were obviously higher than that of the control group (P<0.05). Brain indices of the drowning-to-death group and the 24 h, 40 h survival groups were obviously higher than that of the control group; and those of the 3 h, 12 h survival groups were obviously lower than that of the drowning-to-death group but higher than that of the normal control group (P<0.05). The blood oxygen saturation was (59=5)% immediately after drowning and then gradually increased and reached the normal level after 12 h. The cerebral edema appeared 3 h after drowning and was gradually aggravated from 12 h to 24 h after drowning, then slightly relieved 40 h after drowning. There was no expression of HIF-1α in the control group and lower expression in drowning-to-death group; the expression of HIF-1α gradually increased with the increase of drowning period and reached peak 12 h after drowning(P<0.05); the expression of VEGF had a similar pattern to HIF-1α. The expression of HIF-1α was positively correlated with that of VEGF(r=0.629,P<0.05). Conclusion: Freshwater drowning can cause serious cerebral injury. The brain can be protected from oxygen deficiency by promoting synthesis of HIF 1α and subsequent upregulation of VEGF expression.

OBJECTIVE:To find suitable pharmaceutical care for our hospital. METHODS:The literature research and expert-consultation were adopted to determine the project of pharmaceutical care. Meanwhile,related information were analyzed by the questionnaire survey,statistical analysis interview and other methods in our hospital,such as the content,methods,level and quali-ty of pharmaceutical care. RESULTS:The determined project of the pharmaceutical care and five-point scale were as follows:pre-scription audit 4.53,medication consultation 4.21,prescription analysis 3.56,information about the medication for doctors and nurses 3.73,to establish medical records of hospitalized patients 3.14,ADR monitoring 4.33,drug therapy monitoring 4.31,to par-ticipate in clinical drug therapy 4.03,education about drug use 4.12,to design individualized dosing regimens 3.98,pharmaceutical research 3.58,to popularize pharmaceutical knowledge and education service 4.01. CONCLUSIONS:The hospital should empha-size clincal pharmacist work and software and hardware construction entirely;make the best of modern approach to carry out phar-maceutical care,mainly involving prescription audit and ADR monitoring. However,the problems are that the content of some pharmaceutical cares are not complete,and become a mere formality;clinical pharmacists do not receive systematic trained,the pharmaceutical researches have not been carried out systematically.

OBJECTIVE:To investigate the characteristics of ADR induced by psychotropic drugs in children and adolescent of our center,and to provide reference for clinical drug use. METHODS:ADR induced by psychotropic drugs in children and adoles-cent reported by our center from 2005 to 2015 were investigated and analyzed retrospectively. RESULTS:A total of 177 ADR were collected,of which the most cases were induced by antipsychotic drugs as risperidonal,olanzapine and quetiepine. The most com-mon ADR were central and peripheral nervous system disorders(117 cases,37.86%),followed by endocrine disorder(35 cases, 11.32%),heart rate and rhythm disorders(32 cases,10.35%)and liver and biliary system disorders(17 cases,5.50%). By the relative titer of haloperidol,most of ADR were induced by haloperidol with dose of 4 mg,6 mg and 8 mg once a day(34,29 and 53 cases). Most of cases occurred within a week(94 cases,53.11%). CONCLUSIONS:To develop and strengthen clinical applica-tion and ADR monitoring of psychotropic drugs in children and adolescents should be regarded as the key to ensure drug use safety.

Objective To observe the clinical efficacy of combining Yuan-Primary and Luo-Connecting points in treating insomnia due to imbalance between heart and kidney, for providing novel method and evidence for the treatment of insomnia with acupuncture-moxibustion.Method Totally 100 insomnia patients due to imbalance between heart and kidney were randomized into a treatment group and a control group, 50 in each. The treatment group was intervened by acupuncture at Yuan-Primary and Luo-Connecting points, while the control group was by conventional acupuncture. The Pittsburgh Sleep Quality Index (PSQI), self-rating anxiety scale (SAS), and self-rating depression scale (SDS) were observed before and after intervention for efficacy evaluation.Result The PSQI item scores were significantly changed after intervention in both groups (P<0.05). The SAS and SDS scores were significantly different from that before treatment in both groups (P<0.05). After treatment, the SAS and SDS scores of the treatment group were significantly different from that of the control group (P<0.05). The recovery rate and total effective rate were 26.0% and 92.0% in the treatment group versus 12.0% and 86.0% in the control group, and there was a significant difference in comparing the recovery rate (P<0.05).Conclusion Combining use of Yuan-Primary and Luo-Connecting points is an effective approach in treating insomnia due to imbalance between heart and kidney.
