METHODS: Based on the drug shortage condition in our hospital in recent years, we analyzed the reasons for drug shortage, put forward the solution and summarized the clinically indispensable categories. RESULTS & CONCLUSIONS: We should draw experiences from US by solving shortage problem of certain drugs through the co-efforts of government, manufactures and medical institutions to satisfy patients' needs of disease prevention and treatment.

OBJECTIVE:To prepare hydrocortisone lotion and establish its quality control method. METHODS: The lotion was prepared with hydrocortisone, and the content of hydrocortisone was determined by ultravidet spectrophotometry. The stability of the prepartion and its skin stimulus were investigated as well. RESULTS: The preparation was colorless limpid liquid and up to the standard specified in Chinese Pharmacopeia (2005 Edition) in the related test. The linear range of hydrocortisone was 5.0～30 ?g?mL-1(r=0.999 0) and the average recovery was 100.09% (RSD=0.17%). After storing for 3 and 6 months, respectively, no obvious change was noted for the preparation. The skin stimulus experiment showed that it caused no side effects such as erythema on skin or edema etc. CONCLUSION: This lotion is simple in preparing process, and its quality is stable and controllable.

Long noncoding RNA (lncRNA) refers to RNA transcripts with more than 200 nucleotides in length, which plays regulatory roles directly in the form of RNA. Their functions are affected by their secondary structures, post transcriptional modification and so on. LncRNA can be classified to various subtypes with complicated mechanisms. In human-induced-pluripotent stem cells (iPSCs) and embryonic stem cells (ESCs), dynamic expression of some lncRNAs is detected during the neuronal differentiation, and a series of lncRNAs associated closely with the development process of the central nervous system (CNS) are found. This review summarizes the molecular biological properties of lncRNA and their regulatory functions in the development of the CNS, which is helpful to reveal the mechanisms of the pathogenesis and progression of certain neurological diseases and results in innovation of their diagnosis and treatment.

Objective To evaluate the effects of geraniol(GOH) on neointima hyperplasia in rat carotid artery balloon injury model, and explore the potential molecular mechanisms associated with this effect. Methods Totally 20 male Sprague-Dawley (SD) rats were randomly divided into sham operation group (without balloon injury), control group (with balloon injury), low concentration group (with 50 mg/kg GOH intervention after balloon injury) and high concentration group (with 200 mg/kg GOH intervention after balloon injury). The intima to media (I/M) area ratio of neointima was measured by hematoxylin- eosin (HE) staining. The expression of proliferating cell nuclear antigen (PCNA) was measured by immunohistochemical staining at 14th day after operation. As the marker of oxidative stress, the levels of 8-hydroxy-2’-deoxyguanosine (8-OHdG) and malondialdehyde (MDA) were measured by enzyme linked inmmnosorbent assay (ELISA). Results The I/M ratio, IOD, 8-OHdG and MDA values were increased in control group compared with those of sham group. The I/M ratio, IOD and 8-OHdG values were reduced in low concentration group compared with those of control group. But there was no significant difference in MDA level between low concentration group and control group. The I/M ratio, IOD, 8-OHdG and MDA values were significantly reduced in high concentration group compared with those of control group, which showed a more significant inhibitory effect than that of low concentration group (P<0.05). Conclusion GOH could attenuate balloon iniury induced neointima hyperplasia, which might be related to its effect on inhibiting expression of PCNA and decreasing oxidative stress.

Objective To investigated the analgesic effect of processed Aconiti tuber(PAT) in rats with a sciatic nerve chronic constriction injury(CCI) .Methods The study was conducted in two parts. CCI model was developed with four ligatures placed around the right sciatic nerve and tied without obstructing the blood supply of the nerve. In part Ⅰ, forty rats were randomly divided into five groups(n = 8) . In group Ⅰ normal saline 1 ml , In group Ⅱ-Ⅴ PAT 0.5 ,1, 2 ,or 4 g/kg was administered orally 14 days after CCI respectively. In part Ⅱ , thirty-two rats were randomly divided into four groups (n = 8) . In group Ⅰ oral normal saline 1 ml, in group Ⅱ oral PAT 2 g/kg, in group Ⅲ oral PAT 2 g/kg + intraperitoneal nor-binaltorphimine (nor-BNI) 2 mg/kg, in group Ⅳ oral PAT 2 g/kg + intrathecal nor-BNI 100 ?g was administered 14 days after CCI. As indicators of mechanical and heat hyperalgesia, the paw withdrawal pressure threshold (PWPT) in response to a graded pressure stimulus with a filament and the paw withdrawal latency (PWL) in response to radiant heat were measured in both hind paws before and after drugs administration.Results In part Ⅰ, in group Ⅲ-Ⅴ PWL was prolonged significantly and in group Ⅳ - Ⅴ PWPT were significantly increased compared with those in group I . There was no significant difference in PWL and PWPT between group Ⅰ and group Ⅱ . In part Ⅱ , in group Ⅲ, Ⅳ PWPT and PWL were significantly lower than those in group Ⅱ . There was no significantly difference in PWL and PWPT between group Ⅰ and group Ⅲ, Ⅳ . Conclusion In rat with neuropathic pain processed Aconiti tuber exerts analgesic effect via the spinal ?-opioid receptor activation.

This study was set up to observe the changes in stress and immune functions in upper abdominal surgery after general anesthesia.In thirty elective upper abdominal operation patients,general anesthesia was induced with propofol,fentanyl,scoline and maintained with isoflane and atrumium. Catecholamines(CA),cortisol,interleukin-2(IL-2) and soluble interleukin-2 receptor(sIL-2R) were measured before anesthesia,after induction of anesthesia,at the end of operation,and on the first and third postoperative days.The results showed that epinephrine(E),norepinephrine(NE) concentration increased at the end of operation and on the first postoperative day(P<0.01)，Cortisol concentration decreased after anesthesia induction(P<0.05)，IL-2 concentration decreased at the end of operation(P<0.05)，and sIL-2R lever did not change.The investigation suggested that general anesthesia with propofol,fentanyl and isoflane can suppress CA and cortisol increase resulting from induction of anesthesia. There was no change in IL-2 level.However it can not suppress the increase of stress hormones and decrease of IL-2 due to operation.The stress response correlate with immune functions.
