Objective:To study the regularity and characteristics of adverse drug reaction ( ADR) in our hospital. Methods: A retrospective analysis was conducted on 306 ADR reports collected in our hospital in 2013. The reports were statistically analyzed in re-spect of sex, age, route of drug administration, drug categories, organs/systems involved in ADR and clinical manifestations, classifi-cation of ADR, causality assessment, constituent ratio of the reporters etc. Results:In the 306 ADR reports, the incidence of ADR be-tween the age of 51 and 60 was the highest (20. 26%); the ratio of the ADR induced by intravenously drip administration was the highest in respect of the route of administrations (65. 58%);the radio of ADR induced by antibacterial agents was the highest in re-spect of drug types (20. 78%);digestive system was the maln lesion in ADR cases (23. 91%). The ADR cases were mostly reported by doctors (97. 71%). Conclusion:Our hospital should enhance the ADR monitoring and reporting, promote the clinical rational drug use, reduce or avoid the risk of ADR and protect medication safety of patients.

According to the 2010 Chinese pharmacopeia, salt processed and charcoal processed Eucommiae Cortex were pre- pared. HPLC-DAD analysis of the content of the bark and leaf of Eucommiae Cortex showed that the bark of Eucommiae Cortex mainly contained lignans such as pinoresinol glucose and iridoid including genipin, geniposide, geniposidic acid, while the leaf of Eucommiae Cortex consisted of flavonoids such as quercetin and phenolic compound such as chlorogenic acid. The content of pinoresinol diglucoside in the bark of Eucommiae Cortex was about 18 times more than that in the leaf of Eucommiae Cortex. The content of pinoresinol diglucoside in salted and charcoal processed Eucommiae Cortex decreased approximately by 30% and 85%, respectively. The content of genipin, geniposide and geniposidic acid in the bark of Eucommiae Cortex was about 3 times, 23 times, 28 times more than that in the leaf of Eucommiae Cortex. The content of genipin, geniposide and geniposidic acid in salted Eucommiae Cortex were reduced by 25%, 40% and 40%, respectively. The content of genipin, geniposide and geniposidic acid in charcoal processed Eucommiae Cortex were reduced by 98%, 70%, 70%, respectively. The content of caffeic acid in bark of Eucommiae Cortex was about 3 times more than that in the leaf of Eucommiae Cortex. The content of caffeic acid was decreased by about 50% in the salted Eucommiae Cortex. While the content of caffeic acid in charcoal processed Eucommiae Cortex was decreased approximately 75%; the content of chlorogenic acid in bark of Eucommiae Cortex was about 1/6 of that in the leaf of Eucommiae Cortex. The content of chlorogenic acid in salted and charcoal processed Eucommiae Cortex decreased by 40% and 75%, respectively; the content of quercetin in bark of Eucommiae Cortex was only 1/40 of that in the leaf of Eucommiae Cortex. The content of quercetin in salted and charcoal processed Eucommiae Cortex were reduced by 60% and 50%, respectively.

Objective To analyze the high resolution CT(HRCT)appearance and its clinical significance in patients with post-traumatic visual loss.Design Retrospective study.Participants 150 patients with post-traumatic visual loss.Methods The optic canal HRCT of 150 patients admitted from March to June of 2007 by Department of Emergency for post-traumatic visual loss were ana- lyzed retrospectively.Main Outcome Measures Pedilection sites and their incidence rates of optic canal and orbital apex region. Results Optic canal fractures were found in 78 patients,manifesting as rupture and displacement of optic canal wall,accompanied with or without adjacent structure fractures.(1)Among 88 sides of fractures,22 sides presented with single fracture,and 66 sides with multi- ple fractures,revolving several optic canal walls.(2)156 sites of fractures were displayed in 78 patients,and the most frequent types were displacement fractures(47.4%).(3)Accompanied adjacent structure fractures were found in 73 cases of the 78 patients,while 40 cases were found in 72 patients without optic canal fracture.Totally,283 sites of adjacent structure fractures were discovered with the most frequent sites of orbital apex region,accounting for 44.5%.Conclusion HRCT could well display optic canal fractures and accom- panied fractures of adjacent structures,providing important informations for diagnosis and intervention of traumatic visual loss.(Oph- thalmol CHN,2007,16:326-329)

Objective To observe the effectiveness of dexmedetomidine on postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic cholecystectomy.Methods Seventy patients (17 males,53 females,aged 20-65 years,ASA grade Ⅰ or Ⅱ) undergoing laparoscopic cholecystectomy were randomized to receive either dexmedetomidine (group R,n=35) or dexamethasone (group D,n=35).The patients in the group R received 0.5 μg/kg bolus dose and maintenance dose at the rate of 0.5 μg·kg-1·h-1 of dexmedetomidine before intubation.The patients in the group D received 8 mg dexamethasone before intubation.The BP and HR were recorded at the following points: on arrival in the operating room (T1),before intubation (T2),5 minutes after intubation (T3),5 minutes after the beginning of the operation (T4),30 minutes after the beginning of the operation (T5),at the end of operation (T6) and 5 minutes after extubation (T7).The inhaling concentration of sevoflurane,extubation time,operation time and anesthesia time were recorded.The incidence of nausea and vomiting were recorded at 8,24,48 hours after operation.Results The incidence of nausea and vomiting at each point were similar between two groups.The HR at T2-T7 in group D was significantly lower.But MAP was similar between two groups.Conclusion 0.5 μg/kg bolus dose and maintenance dose at the rate of 0.5 μg·kg-1·h-1 of dexmedetomidine reduced the incidence of PONV in patients undergoing laparoscopic cholecystectomy,similar to dexamethasone.

OBJECTIVE: To investigate effects of antioxidant stress protein heme oxygenase-1 (HO-1) on lipopolysaccharide (LPS)-induced endoplasmic reticulum stress (ERS) of rat hepatocytes. METHODS: The BRL cells (rat hepatocyte cell line) were cultured. The hepatocytes were treated with LPS, LPS+HO-1 siRNA, HO-1 siRNA and PBS solution, respectively. The cell viability was measured by trypan blue exclusion test. The apoptosis cells were detected by the fluorescent dye Hoechst 33258. Expressions of GRP78, CHOP, caspase-12 and HO-1 were detected by Western blotting. RESULTS: LPS caused an increase of HO-1 protein expression of rat hepatocytes in a dose-dependent and time-dependent manner, a up-regulation of GRP78, CHOP and caspase-12, a decrease in cell viability, and an increase in apoptosis rate of hepatocytes. Pretreatment of HO-1 siRNA inhibited the up-regulation of LPS-induced HO-1, however, aggravated ERS and cellular injury. CONCLUSION HO-1 inhibites ERS-mediated cellular injury of rat hepatocytes induced by LPS.

Objective To study the CT and MRI findings of osteosarcoma in paranasal sinus and evaluate their clinical value.Methods All 9 cases of osteosarcoma were verified by histopathology.Imaging data were analyzed retrospectively.Results The lesion occurred in maxillary sinus in 5 cases,in ethmoid sinus in 3 cases and in sphenoid sinus in one case.Primary osteosarcoma was found in 7 cases.Secondary osteosarcoma occurred from fibrous dysplasia and ossifying fibroma each in one case.On CT,the involved areas revealed bony destruction associated with ill-defined and irregular soft tissue mass.The lesion showed heterogeneous density with minimal or massive tumor bone formation,cloud-like in 3 cases,ivory-like in 2 cases,spicule-like in 2 cases,cloud- and spicule -like in one case and spicule- and ivory-like in one case.Postcontrast CT showed mild to moderate inhomogeneous enhancement in 3 cases.On MR T_1 WI,the lesions showed hypointensity compared to brain in 5 cases and iso-intensity in 2 cases.On T_2WI,the lesions showed heterogeneous hyperintensity in 4 cases and isointensity in 3 cases with marked hypointense foci which corresponded to tumor bone on CT.Postcontrast MR imaging demonstrated moderate to marked inhomogeneous enhancement in these cases.MRI showed accurately the extent and associated changes of the lesions.The lesions invaded the orbit,pterygopalatine and infratemporal fossae,skull base and extensive craniofacial structures in 5,4,3 cases and 1 case,respectively.Conclusion CT is the optimal modality in showing tumor bone of osteosareoma in paranasal sinus.MRI can demonstrate optimally the invading extent of the lesions.Combined imaging modalities can provide more comprehensive information for diagnosis and therapy of osteosarcoma in paranasal sinus.

Objective To investigate the CT and MRI findings of cavernous hemangioma in paranasal sinus so as to promote the diagnostic accuracy.Methods All 30 cases of cavernous hemangioma in paranasal sinus were verified with pathological examinations.The CT and MRI findings were analyzed retrospectively.Results The lesions occurred in the maxillary sinus in 25 cases,in the anterior ethmoid sinus in 3 cases and in the sphenoid sinus in 2 cases.The lesions extended and compressed adjacent structures.MRI showed the extent and the associated changes of the lesions more clearly compared to CT. On CT,all the involved paranasal sinuses invariably expanded.The bony walls of paranasal sinuses were compressed and remodeled with focal defect in 28 cases,mostly in the medial wall of the maxillary sinus (21 cases).Bony scelerosis of the residual walls of paranasal sinus were found in 8 cases.The lesions demonstrated well-defined margin and heterogeneous density with phlebolith in 10 cases.Postcontrast CT showed marked inhomogeneous enhancement in 16 cases.On MR T_1WI,canernous hemangioma showed hypointense signal compared to brain in 4 cases and isointense signal in 14 cases.On T_2WI,the lesions revealed heterogeneous hyperintense singal in 16 cases and isointense signal in 2 cases with multiple hypointense foci.Postcontrast MR imaging demonstrated marked inhomogeneous enhancement in these cases,honeycomb-like appearance in 8 cases and variegated appearance in 10 cases.The feature of progressive enhancement was found on dynamic contrast enhancement of MRI in 8 cases.Conclusions The characteristic bony change together with phlebolith can suggest the diagnosis of cavernous hemangioma in paranasal sinus on CT.The heterogeneous hyperintense singal on MR T_2WI,progressive enhancement and honeycomb-like or variegated appearance on postcontrast MRI were also the characteristic findings of cavernous hemangioma in paranasal sinus.Combination of CT and MRI findings can provide more accurate information for the diagnosis and therapy of cavernous hemangioma in paranasal sinus.

OBJECTIVETo study the therapeutic efficacy of Lixue Xiaoyin Decoction (LXD) in treating psoriasis and its effect on plasma endothelin (ET).

METHODSTwo hundred and twenty patients were divided into two groups. LXD was taken orally by the 118 patients in the treated group, while Compound Qingdai Capsule (CQC) taken orally by the 102 patients in the control group. The therapeutic efficacy was evaluated after 8 weeks of treatment. The ET content was determined by radioimmunoassay before and after treatment.

RESULTSThe total effective rate was 73.72% in the treated group and 54.90% in the control group with significant difference (chi2 = 8.52, P < 0.01). The plasm ET level in patients was significantly higher than that in the healthy subjects. ET in both groups was all lowered after treatment, but the decrement was more obvious in the treated group, showing significant difference when compared with that in the control group (P < 0.01).

CONCLUSIONLXD shows good therapeutic efficacy in the treatment of psoriasis. It can improve the microcirculation, inhibit the division of epithelial cells, promote the epidermic cell differentiation, and shows regulative effect on plasma ET.
